A, PREFACE TO THE THIRD EDITION This edition has been prepared with the assistance of my former asso- ciate, Dr. Gaylord Willis Graves, who will hereafter be connected with the work as co-author. The book has been largely rewritten, with the addition of much new material both in the form of text and illustrations. In particular the additions comprise consideration of the following subjects: Growth and Development, Methods of Infant Feeding, Developmental Gastro-intestinal Abnormalities as Shown by z-Ray, Scurvy, Rickets, Asthma, Pneumonia, Influenza, Endocrine Disorders, Nephritis, Tetany, Hydrocephalus, Epi- demic Meningitis, Encephalitis Lethargica, Smallpox, Measles, Diphtheria, Scarlet Fever, Acidosis and Alkalosis, Diabetes Mellitus, Acrodynia, Defective Bodily Mechanics, Foreign Bodies, Diagnostic Methods, and Special Therapeutic Procedures. A number of the older articles and illustrations have been omitted as no longer essential. With the incorporation of new material the foot-note references have been greatly supplemented. The authors desire to express their indebtedness to Dr. Howard Reid Craig for valued assistance in the preparation of the work, and to acknowl- edge helpful courtesies from the staff of the Children’s Medical Division of Bellevue Hospital.

NUTRITION—GROWTH—DEVELOPMENT Nutrition and Growth The fundamental principles in the life of the young of all animals are growth and development. This statement applies to the young of the lower animals as well as to man. Nature has fixed and definite laws in accordance with which this growth and development proceed. The type of animal produced depends in no small degree upon the way in which we comply with these laws. Heredity.—Inheritance is, of course, an important factor, but environ- ment counts for more. The young of the lower animals or of man may possess all that can be desired in the way of heredity, but if manage- ment during growth is faulty, the adult is almost certain to fall short of the normal. On the other hand, an individual without the benefits of good heredity, when given the advantages of faithful scientific care may develop into an adult decidedly superior in all respects to those more fortunate in birth. Environment.—One who carefully watches the growth and develop- ment of animals will observe that under care as to feeding, housing, ventilation, cleanliness, and exercise, those which promise but little at birth develop into perfect specimens of their kind. Similarly, prolonged intimate association with thousands of infants and growing children in private, in hospital, and in out-patient work inevitably impresses upon a physician the possibilities of growth under good management even when little has been expected, judging from the original condition of the patient. The child is here through no choice of his own. He is to have a future. Because his health, vigor, powers of resistance, happiness, and usefulness as a citizen are determined in no small degree by the nature of his care during the first fifteen years of life, he has a right to demand that such care be given him as will be conducive at least to a sound, well-developed body, and this should be our first thought and object regarding him. Consider for a moment the number of occupations, other than those of the army and the navy, that require physical fitness before a candidate is accepted. Competition is keen at the present time and will be keener in the future. Employers of men and women, whether in the office, the factory, or on the farm, cannot afford to utilize the physically weak. Care and Feeding.—The most important physical factor in the making of men and women is nutrition. No great power of reasoning is required to appreciate the fact that the child who is fed on suitable food will become 17 18 THE PRACTICE OF PEDIATRICS a more vigorous, better developed adult than one who, beginning at birth and continuing throughout the entire period of growth, is given only food possessing indifferent qualities for tissue building. Next in importance to food, and following in close correlation, are fresh air, cleanliness, cheerful surroundings, and healthful amusements, together with an absence of school work or service of an arduous nature. That the offspring of man suffers more from nutritional errors due to the lack of suitable care than do the young of the lower animals is lamentable, but nevertheless a fact. The absence of thought and care and of knowledge relating to children is due to the fact that the child as such has apparently no intrinsic value in dollars and cents, whereas the young of the lower animals represent no small part of their owner’s material possessions. Another factor having a deterrent influence upon the development of children is their unfavorable start during the first year. Positive success in the management demands daily attention to detail. Feeding the child properly one or two months out of the year is of little value. He should be fed properly every day in the year, for under normal conditions every day is a day of growth. Unfortunately, many mothers cannot supply to the infant the requisite nourishment. This brings us to the matter of substitute feeding, fraught with per- plexities and uncertainties in the most competent hands, and with dan- gers and disasters in the hands of the incompetent and inefficient. In the section on Artificial Feeding of infants their nutrition is considered in detail. It is sufficient to remark here that nature has provided for the baby a food which contains the nutritional elements, fat, sugar, and protein, in fairly definite proportions and in peculiar forms. Success in substitute feeding depends upon our ability to supply in suitable forms, and the child’s ability to assimilate, a food containing the nutritive elements in approximately the quantities found in human milk. An exact reproduction of mother’s milk by the use of cow’s milk or other food is, of course, impossible. We can imitate human milk, however, with sufficient accuracy to make acceptable and sufficient food for most children who are deprived of the breast. After the nursing or the bottle age the feeding must not be left to the family judgment, for at this period of rapid growth suitable nutrition is most important. Left to the family, the diet during the second year too frequently consists of milk, which in large cities is often of uncertain nutritive value, together with insuffi- ciently cooked cereals, boxed breakfast foods, bread-stuffs, crackers, and cake—often procured at the grocer’s or baker’s. At the Out-patient Departments of the New York Babies’ Hospital and the New York Poly- clinic Medical School only 20 per cent, of a large group of the children treated who were over one year of age were found to be of normal de- velopment. In those under one year of age only 35 per cent, were nor- mal. While these groups are not to be considered as representing the country as a whole, still they do represent a large part of the population of our larger cities, the offspring of day-laborers, drivers, waiters, and small-wage earners generally. Such children were fed in the manner above described, not because of poverty, but because of an absence of the slightest knowledge on the part of the parents regarding suitability of foods. The children were not hungry, and were fed to satisfy taste FOOD PROPERTIES AND PHYSIOLOGIC REQUIREMENTS 19 rather than true appetite; when that was accomplished the parents considered their duty done. To feed with a definite purpose—with a view solely to the physical development of their children—had never entered the minds of the parents, yet most of them could read and write and possessed a fair degree of general intelligence. They were conversant with affairs and had attended the public schools, but were absolutely untaught as to how they should live. FOOD PROPERTIES AND PHYSIOLOGIC REQUIREMENTS Substances used as foods, regardless of the animal which they may nourish, possess the common property of being composed of fat, protein, carbohydrate, mineral substances, and water in varying proportions. The purposes that these serve in the animal economy are essentially the same in all forms of animal life. In order to determine the food value of any substance a chemical analysis which shows the quantities of these nutritional elements is required. It will be found that foods varying widely in appearance and physical properties are still similar in that they are composed of the same food elements, although in different proportions. Foods used to sustain animal life of any kind must contain the in- gredients needed by all animals, and in a form suited to the particular kind of animal to be fed, whether it is man or one of the lower animals. The Ingredients of Foods.—While all foods are composed of fat, carbohydrate, protein, mineral substance, and water, these elements exist in widely differing forms. Fat may be supplied in meat, egg, milk, butter, oleomargerine or butterine, lard, olive oil, cod-liver oil, linseed oil, cottonseed oil, etc. Carbohydrates may be furnished in the form of cane-sugar, milk-sugar, maltose and dextrose, soluble products derived from starch, cornstarch, wheat or other flour, oatmeal, rice, hominy, bread, potatoes, etc. Proteins are secured in the form of lean beef, lamb or pork, chicken, fish, the gluten of such cereals as wheat and oats, in large quantities from peas, beans, lentils, and other legumes, from the curd of milk, and also from eggs. The mineral substances of food are found combined with the other ingredients in the form of lime, phosphates, magnesium, iron, etc. The Function of the Food Elements.—The proteins of the food are used to form the bodily structures and to replace tissue consumed by the vital processes and excreted as urea. The vital processes, such as the circulation of the blood, respiration, and contractions of the muscles, call for energy, and this together with bodily heat must be supplied by the fats and carbohydrates. The mineral substances are used in the formation of bone and teeth, while the water serves to dissolve the food elements after they have been digested and to carry off waste products. As the demands made are variable and directly dependent upon numerous changing conditions both within and without the body, food must be varied in amount and character to meet the altering demands. Exercise, variations in external temperature, lowered digestive capacity, illness accompanied by fever, growth, and repair all have to be considered apart from the conditions attendant upon the so-called basal metabolism of the resting organism. Thus meat, with its abundance of protein, serves as the chief food of the laborer expending muscular energy, fat 20 THE PRACTICE OF PEDIATRICS serves as the reserve store of the Eskimo, and carbohydrate, by reason of its easy digestibility and ready availability as fuel to spare tissue waste, is of great value in disease states associated with fever. When one thus considers food in the light of its component elements more detailed knowledge is seen to be essential to any mastery of the subject of nutrition of the growing body. Proteins.—These are commonly called nitrogenous foods because of the characteristic presence of nitrogen in the complex protein molecule. The nitrogen component makes the protein element in food invaluable for tissue growth and repair, while the carbon available in protein supplies heat and energy. Protein is thus the one complete food, but it has the disadvantages of being less concentrated in caloric value and less stable under the influence of physical and chemical agencies, including bacterial, action, than many forms of carbohydrate and fat, while the difficulty of absorption and elimination of some forms of protein has also to be reckoned with in the problem of diet. Not to be forgotten is the fact that the most expensive foods are usually those high in protein, and that protein sus- ceptibility or anaphylaxis exceptionally constitutes a contraindication to the use of certain foods by certain individuals. Of the numerous amino-acids into which the protein foods are event- ually broken down in the digestive canal, lysin, cystin, and tryptophan are of greatest value for growth. Fat.—For purposes of nutrition, fat is of value as a protein sparer of very high caloric value. In spite of its relatively slow digestibility it is largely absorbed, and besides serving as a fuel of slow combustion is readily stored up. The unoxidized intermediate products of fat metabolism may lead to acidosis, particularly if there is not enough available carbohydrate to “make fire” for their complete oxidation. Calcium and other mineral substances are ordinarily stored more readily in the body when the fat intake is adequate. This is illustrated by the rapid lowering of calcium excretion in rachitic subjects when cod- liver oil is added to a previously deficient diet. Carbohydrates.—These not only serve as protein sparers, but are im- mediately available for combustion. When stored as glycogen, carbohy- drates may be transformed into fat. Of the two chief forms of carbohydrate, the sugars and starches, the former are absorbed most readily, but by reason of their ready fer- mentability not infrequently contribute to vomiting and diarrhea. To safeguard against this possibility we employ mixtures of starch and sugar in order that absorption may take place at more than one level in the digestive tract, thus entailing less risk of fermentation than would exist if the stomach were required to do all the work. Starch after being converted into dextrin and then maltose eventually breaks down into two molecules of dextrose; cane-sugar is split into dex- trose and levulose, and lactose into dextrose and galactose. The argument as to what is the best form of carbohydrate to ad- minister in a given case always evokes controversy, but in general one has only to remember the following facts: Lactose, the natural milk sugar, ferments more readily in the intes- tine than in the stomach and is more slowly absorbed than maltose. FOOD PROPERTIES AND PHYSIOLOGIC REQUIREMENTS 21 Cane-sugar has the great advantage of cheapness and availability. Maltose is readily absorbed, but not infrequently conduces to gastric fermentation. Dextrin derived from starch has a protective colloid action, and undergoing slow change to maltose does not readily contribute to sugar excess in the intestine. This subject will receive further consideration under the discussion of Artificial Feeding of infants, p. 69. The Mineral Substances.—A discussion under this heading leads one immediately into the chemistry of bodily structure as well as that of function, and the problem involved belongs to a special sphere of medi- cine. We may remind ourselves, however, that in milk we have relatively large amounts of the calcium, phosphorus, and magnesium salts necessary for bone development, whereas we are confronted with a lack of iron so essential to the blood. At an early age the requirements of the infant must therefore be met by the use of supplementary foods, particularly iron containing vegetables, meat juice, and egg. Vitamins.-—A definition of these substances may hardly be made specific. In general, vitamins are accessory elements in raw foods, of little or no caloric value, but of vital importance even in minute quan- tities to the maintenance of health and nutrition. Vitamin A, or the fat-soluble vitamin, is found in cream, egg yolk, and cod-liver oil, but is lacking in vegetable oils. It is not appreciably affected by heat. Vitamin A has been called the antirachitic vitamin because of the demonstrable value of the substances which contain it, particularly cod-liver oil, in the prevention and cure of rickets. Whether the term “vitamin” really belongs to the “antirachitic principle” in the cod-liver oil remains to be proved. Vitamin B, a water-soluble vitamin, occurs in yeast, husks of grains, milk sugar, and a large range of vegetable foods. It is affected, but not rendered inadequate by heat. By reason of its preventive and curative value in polyneuritis and beriberi vitamin B is called antineuritic. Vitamin C, water soluble, is found in fruit and vegetable juices, par- ticularly oranges, lemons, tomatoes, and potatoes. It is present also in small amount in raw milk. This vitamin is destroyed by heat. Its absence for a long period from the diet may lead to the development of scurvy. For this condition, moreover, it is specifically curative, consequently bearing the name antiscorbutic vitamin. Water, the remaining food constituent, comprises about 87 per cent, of milk and is present in large amounts in a wide variety of natural foods. In health its importance is not likely to be forgotten. Nevertheless, wrong notions on the part of the laity sometimes preclude adequate fluid intake in illness. For the digestion of food, the radiation of heat, the dilution of toxins in the circulation, and the proper functioning of the bowel and kidneys the administration of water by at least some avenue of entrance to the body must always be maintained. The Advantage of a Knowledge of the Composition of Foods.— Inasmuch as each food element has a special function to perform, and 22 THE PRACTICE OF PEDIATRICS since growth is impossible without a sufficient supply of these nutri- tional elements, particularly the protein, it is essential to know within reasonable limits the composition of a food, because if the elements are not present in proper proportions, disappointing results may be obtained from its use. Difficulty which may appear inexplicable will readily be accounted for if we know what element of the food is at fault. For these reasons it is coming to be the practice, in infant feeding especially, to speak of the percentage composition of the milk foods, as, for example, a food containing 4 per cent, fat, 7 per cent, carbohydrate, 2 per cent, protein, and 0.35 per cent, mineral substances. Knowing from wide experience the percentages of these ingredients generally needed in a food if it is properly to nourish a child, the physician can determine in an instant whether an infant is having a food of suitable nutritive value by com- paring its known composition with that established, by experiment, as requisite. Values of Common Foods.—The following table shows the average chemical composition of a few of the more common American foods1: Food material. Water, per cent. Protein, per cent. Fat, per cent.

FOOD PROPERTIES AND PHYSIOLOGIC REQUIREMENTS 23 The One Hundred Calorie Portion.—For rough computation one may base estimates on the 100 calorie portion into which many articles of food naturally fall.1 Examples of food portions containing about 100 calories are as follows: Milk 5 ounces Meat 2 ounces (1 chop) Fish 3 ounces Bread 1 slice (3x3x1 inch) Potato 1 medium Sugar 2 tablespoonfuls Apple, orange 1 of good size Egg H Caloric Requirements.—The actual requirement in calories per diem depends on many factors, not the least important of which is the age of the individual whose needs are to be met. During infancy the caloric requirement usually accepted is 100 per kilogram or 45 calories per pound of body weight. During the first few weeks of life the requirement ranges from 25 to 35 calories per pound of body weight. The following table gives the calories per day required by children of different ages, as estimated by Miss Gillett.2 FOOD ALLOWANCES FOR CHILDREN (GILLETT) Age, years. Calories per day: Boys. Girls.

Holt and Fales3 found that the average for three of the component factors which go to make up the total requirements (i. e., basal metabolism, growth, and excretion) is nearly uniform for children of the same weight under similar living conditions, but that the requirement for activity 1 Vide Fisher’s Table of One Hundred Calorie Portions, Jour. Amer. Med. Assoc., 1907, xlviii, 1320. 2 Food Allowances for Healthy Children, Pub. 115, New York Assoc, for Improving the Conditions of the Poor, 1917. s Amer. Jour. Dis. Child., January, 1921. 24 THE PRACTICE OF PEDIATRICS varies markedly. According to these writers the following is the average caloric requirement for children: At one year, 100 calories per kilo. At six years (for children weighing 20 kilos), 80 calories for boys, 76 calories for girls. At ten to fifteen years, 80 calories for both sexes. After fifteen years for those weighing at least 50 kilos, about 48 calories. These investigations confirmed Benedict’s statement that a most lib- eral diet is desirable for children, since evidence indicates that children receive too little rather than too much food. The Value of Caloric Feeding.—The caloric standard in its application to infant feeding is further considered in a later section (p. 67). The method has been severely criticized and there is little doubt that its value is greater as a check than as a guide for the dietitian. Computations based upon weight alone are misleading and are being replaced by those which take into account the relation between body surface and basal metabolism. Upon this subject the work of DuBois, Benedict, Harris, Gephart, and others has been in the front rank. The Feeding Method of the Von Pirquet School.—This method was a direct outgrowth of needs existing in Vienna as a result of the World War. The founder concluded that the square surface of the intestinal canal was the best measure of the amount of food one required as a daily allowance, and he estimated this surface as equal to the square of the individual’s sitting height. He further coined the word “nem” (“nahrungs einheit milch,” nutritional unit milk) to express the value in energy of 1 gram of mother’s milk. This was selected as the basic food in terms of which all diets were calculated with due allowance for the factors of age, activity, and illness. In the feeding of large numbers this ingenious method as applied abroad proved of great value. The system, however, has as yet not been generally adopted in this country, and whether the “nem” will re- place the calorie in our computations remains to be proved. The Selection of Food.—In a review of analyses of foods many sub- stances will be noticed which, according to their chemical composition, have the same food value, but which obviously are not interchangeable. For instance, no one would attempt to feed to a human being cracked oats unless thoroughly cooked, but he would give them raw to the lower animals. Oats will nourish a man or the animal equally well, but for man they must be prepared, while the horse, for example, can utilize them in their original state. This illustrates the importance of adapting food to the consumer. Often the question in feeding is not so much, Is the food nutritious? as, Can the patient assimilate it? Thus, success in infant feeding lies in the physician’s ability to discover a form of fat, carbohy- drate, and protein which the infant can assimilate. In the following pages feeding measures for temporary use will be described which may not conform to what may seem strictly scientific principle, yet often give brilliant results. Looking a little below the surface one will discover that the measures suggested are not unscientific, and that the results are due to applying the fixed principles of nutrition in perhaps novel or unusual AIDS TO NUTRITION 25 ways. It is usually best to follow the most direct route to any place, but when this is badly blocked it is better to go another way, if there is one, rather than not to arrive at one’s destination. General Properties of Milks.—When most young animals are born their digestive organs are in a more or less embryonic condition, and it is several months before they entirely outgrow this state. During this period the nourishment is supplied by the mother through her mammary glands, first as colostrum and later as milk. When these secretions are analyzed they are found to consist of fat, carbohydrate, protein, mineral substances, and water, and in this respect they do not differ from other foods. But the elements exist in the secretion in peculiar forms, and the natural inference is that in some way this food must be particularly suited to animals whose digestive organs are still undeveloped. The digestive secretions of the stomachs of all known animals contain pepsin and hydrochloric acid. In the very young these secretions are feeble, but as development proceeds they are much more abundant. To understand milk as a food one must know the effect upon it of pepsin and acid. When pepsin is added to tepid cow’s milk it causes the milk to solidify, with the formation of curd or junket. If the milk is slightly acidified or soured, the curd formed is dense and solid and more difficult of digestion. When the milk of the cow, of the ass, and human milk are separately treated with pepsin and acid in exactly the same way, curds totally different are formed, and as the human digestive organs are different from those of the cow or the ass, it is believed that these differences in the digestive properties of milks are for the purpose of mak- ing the milks suitable for the different kinds of digestive tracts. Milks may be regarded as special forms of food which require greater digestive effort as the digestive secretions of the stomach become stronger, and thus solid food is furnished to the developing stomach. It is that portion of the protein of the milk called “casein” that is changed into a solid by the pepsin of the stomach. The term “casein,” however, has been loosely applied to all the proteins of all milks. The caseins of all milks are not alike in their digestive properties and the mistake of so considering them should be guarded against. A consideration of such a modification and adaptation of cow’s milk as will make not only the protein but the other ingredients acceptable to the infant’s digestive capacity will be found in the chapters dealing with Substitute Feeding. Aids to Nutrition Fresh Air.—Doubtless the next most important factor after food and the means of giving it is good air. It is a just criticism of the average American that he is afraid of fresh air not only by night but by day. Ventilation is one of the most difficult features of a child’s management with which the physician has to deal. Mothers will feed the children in detail according to instruction and will bathe them and follow out to our satisfaction every order and direction. The stumbling-block is the open window. It is to be hoped that a knowledge of the means and results of treating tuberculosis by open-air methods, and the recent agitation concerning the treatment of pneumonia and other infectious diseases 26 THE PRACTICE OF PEDIATRICS along similar lines, may so permeate the minds of the masses as to quiet their fears regarding dangers of outdoor air. While the child is out of the living-room or nursery the room should be ventilated by opening all the windows, when family conditions allow, the nursery always being aired in this way. The sleeping-room should always be aired for one hour before the child is put to bed. Indoor airing for which the child is dressed as for going out, placed in his carriage or cart, and wheeled up and down the room for an hour or two with the windows wide open regardless of the weather, is most satisfactory in treating very young and delicate children, and promoting convalescence from illness. On.inclement days the well child accustomed to his daily outing will be greatly benefited by the indoor airing. It is fully ap- preciated that such a course of management is impossible in many house- holds. The scheme is the ideal one, however, and should be followed out as closely as possible. The Window-board.—A convenient and simple means for ventilating the living-room, sleeping-room, or sick-room of a child in cold weather is what is known as the window-board. A plain inch board is sawed the width of the window-frame and placed under the raised window in the lateral frame groove, resting upon the sill. This raises the top of the lower sash above the bottom of the upper one, leaving a space between through which the air enters with the current directed upward. The board may be of any width—4, 6, or 8 inches. A width of 6 inches is commonly used. There are various ventilating devices in the market. Those that are of value are expensive, and their effectiveness over the simple means above suggested does not always warrant the expenditure. Sunlight.—Long before Rollier, who has been called the High Priest of Modern Sun Worshipers, opened his first clinic at Leysin in 1903, the value of sunlight had been appreciated. As heliotherapy is developed more highly and the relative value of the different component rays of the spectrum is being accurately determined, knowledge that had been only empirical is being established as scientific truth. “Who would have guessed,” wrote Saleeby,1 “that a few minutes’ exposure to sunlight will double the quantity of phosphorus in a baby’s blood in a fort- night.” Dick, writing of the geographic distribution of rickets, has shown a direct relationship between its incidence and the amount of sunlight available to the inhabitants of a country. Recently the fact that sunlight which traverses window glass is deprived of its actinic rays and is no longer appreciably curative has been established. In detail the effects of sunlight are to promote a rise in body tem- perature, surface pigmentation, better nutrition of skin and muscles, and increased reaction against disease foci, such as those of tuberculosis. Vari- ous skin diseases, tuberculosis, rickets, arthritis, lymphatic gland diseases, and even leukemia have all been benefited by the solar rays. To the growing child outdoor sunlight is a first essential. Suitable Clothing.—If this problem were submitted to the best ex- ponents of heliotherapy, the answer would be no clothing; for their work has shown conclusively that the body is soon inured to temperature 1 Rollier, Heliotherapy, 1923, p. 17. AIDS TO NUTRITION 27 changes, and even when undergoing the depletion of actual disease, such as tuberculosis, may show most rapid recuperation if the surface is com- pletely exposed to light and air. Practically, however, the overheated modern apartment, on the one hand, and the slush-filled, wind-exposed street on the other, make for a situation that must be met by individual care. Particularly in the case of the delicate child proper clothing thus becomes a chief aid to nutrition. A mixture of silk and wool or linen mesh next the skin is uniformly desirable. For the infant the circular abdominal band is a physiologic asset, and this may well be worn until after the completion of the first year even when other clothing is very light, particularly if there is a ten- dency to gastro-enteritis, which is readily aggravated by chilling of the surface. Outer clothing rather than the underclothing should be varied to meet weather changes and should insure at all times warm hands and feet. Further than this one needs not to advise, particularly when every nursery is flooded with literature concerning the details of the baby’s and child’s habiliments. For a baby on very hot days a napkin, a muslin slip, and a band com- prise complete equipment. Bathing.—The necessity for the daily bath is appreciated and acted upon by nearly all classes of society. From the time the cord falls and the cicatrix forms, the well infant or child should have one tub-bath daily. If he is too ill for the tub, he is not too ill to be sponged. Relaxation.—The well child is naturally good natured and happy. When such is not the condition, we have not a well child to deal with. Something is wrong. Perhaps it is the home management. Adults often forget that exuberance of spirits and thoughtlessness belong to childhood. Persistent child nagging becomes a habit with many parents and teachers; in fact, irritable mothers usually have irritable children. Work involving strain, whether physical or mental, should form no part of the life of the child. In our modern school system the forcing process, the competi- tions, and the giving of rewards of merit are all pernicious practices. As a result of the competitive system, progress, to be sure, is made along intellectual lines, but at the expense of the physical; and what does intel- lectual attainment count for in a weakly or diseased body? A child cannot do hard mental work, such as is required of many children from the tenth to the fifteenth year, and be expected at the same time to develop to the best advantage physically. The appetite and digestive power, the capacity for taking and assimilating food, is diminished. The result is apparent in hundreds of cases. On the streets in New York two pictures always fill us with pity. One is that of the pale, slender school-girl strug- gling home with a load of books. (Such a child had 11 text-book studies besides piano and dancing lessons!) When the question is asked the child or the parents as to the necessity for all this work and worry and the close confinement which it entails, the reply almost invariably is that all the girls of her age do the same and she does not want to be behind. The other picture is that of the “little mother”—a pale, wan, tired child from seven to twelve years of age who “minds the baby” and the other younger members of the household while their mother is away from home or at work. Children so abused are happily growing fewer, owing 28 THE PRACTICE OF PEDIATRICS to various factors which need not be discussed. It is needless to say that neither type of girl makes the ideal woman or mother in any station in life. The condition of boys who work in factories, sweat-shops, or else- where is no better. When too much energy is expended in work, food cannot go to the building up of a strong, normal body. The State is the loser and the child is robbed of his birthright. It is the duty of physicians to explain in detail to parents their re- sponsibility as regards the physical welfare of their children. Parents, as a rule, are ignorant concerning a child’s management; but they are anxious and willing to do the best things possible, and will carry out sug- gestions if we take the trouble to enlighten them as to their errors. Sleep.—The infant who sleeps well is almost always a normal, well- fed baby. Irritability and sleeplessness are associated with indigestion more frequently than with any other disorder. During the first few days of life the sleep, in normal conditions, is almost unbroken, except when the infant is fed. During the first month the infant sleeps about twenty- two hours out of every twenty-four; during the second and third months, from twenty to twenty-two hours. At the sixth month the child should sleep from 6 p. m. to 6 a. m. without interruption except for feeding or nursing, which need cause very little disturbance. At this age there should be a two-hour nap during the morning and a two-hour nap in the afternoon, although it is not well to have the baby sleep after 3 o’clock in the afternoon. The twelve-hour night rest should be continued until the child is six years of age. The day naps will gradually be shortened by the child. At one year of age one hour in the morning and two hours in the afternoon suffice. From the eighteenth month to the second year the morning nap may be given up. Afternoon rest for at least one and one-half hours should be continued until the sixth year of age, and longer if the child is inclined to be delicate. Regular sleep is largely a matter of habit, and if the infant is started right with suitable feedings given at definite times, followed by the proper period of sleep, little trouble will be experienced. When sleep is disturbed and broken the condition means bad habits, unsuitable food, minor forms of indigestion, or positive illness of some kind. Sleep is important for purposes of growth, not only in early infancy but throughout childhood. Not a few infants form habits of sleeping in the daytime and being wakeful at night. This is best remedied by keeping the baby awake during the day by entertain- ment and by keeping him in a well-lighted room. A proper amount of sleep is most essential to nutrition, and we are sure that the satisfactory results achieved in the treatment of secondary malnutrition and anemia have been due in part to insistence that the child sleep in a quiet, darkened room for two hours after the noon-day meal. The energy expended in twelve hours by an active child is incalculable, and when a portion of this energy is reserved and the body fortified by rest and sleep dui'ing the middle of the day, there is a greatly diminished daily expenditure of strength units. Crying as Exercise.—Notwithstanding the desirability of sufficient sleep it is well for the young infant to cry a little every day. Muscular movements involving a greater part of the body accompany the act of crying and furnish exercise. Peristalsis is increased, as is often evi- AIDS TO NUTRITION 29 denced by a movement of the bowels occurring during crying, particu- larly when there is diarrhea. In crying, deep breathing is necessary, the lungs are expanded, and the blood oxygenated. In this respect crying itself is an aid to growth and development. The well baby cries when frightened, or uncomfortable from hunger, soiled napkins, or irritated buttocks. He cries from pain, from heat, from cold, from unsuitable clothing, and during difficult evacuation of the bowels. He also cries when displeased or angry. Authors are prone to refer to the diagnostic value of an infant’s cry. It is probable that characteristic cries are not to be depended upon suffi- ciently to give them a differential diagnostic dignity. Children slightly but painfully ill may cry incessantly for an hour or two. Thus, with intestinal colic, the cry is loud and continuous until the child is relieved or falls asleep from exhaustion. Earache is not an infrequent cause. The habitual criers, the restless and vigorous, crying, whining infants, are uncomfortable. With very few exceptions the trouble will be found in the intestinal tract. The well-trained, normal child, whose nourish- ment is suitable, is seldom troublesome. When well, all babies are naturally good natured and happy in their own way. Badly managed, spoiled infants often cry vigorously when left alone. When attention is given them, when they are taken up and talked to, the crying ceases. This readily tells us that pain or discomfort was not an element in causing the cry. By these infants discipline, not medication, is needed. The management of the habitual crier calls for the relief of the condition which causes the discomfort, or the most rigid discipline, when it is dem- onstrated that we are dealing with a “spoiled infant.” The Nursery Maid.—In certain stations and conditions of society the young child is cared for by the mother with the assistance of the im- mediate members of the family. In thousands of homes, however, a helper is employed to take charge of the child or assist in the care. The selection of a nursery maid is consequently a matter of much importance. Schools for training nursery maids exist in New York, Boston, Albany, Newark (New Jersey), and doubtless in many other cities. Although such trained help is greatly to be desired, the supply is very limited. Some of the best children’s attendants have been women who, although they have not passed the meridian of life, still have reached the seasoned age when the attractive qualities of policemen and grocery boys have faded into a dim recollection. Any industrious, sensible young woman of quiet tastes who is fond of children can be trained in a few weeks into a most useful helper. The association of the nursery maid and child is a close one, and it is the physician’s duty to know that the applicant is phys- ically fit for the position. During a single year the senior writer has known of three nursery maids who developed pulmonary tuberculosis while in service. Numerous similar instances have been cited by other observers.1 Not only should the applicant’s lungs be examined but also the mouth, nose, and throat. Carious teeth and .diseased conditions of the throat and nose should receive careful attention before the maid is allowed to assume the position. 1 Healthy Servants Only in a Healthy Home, by Charles Hendee Smith, M. D., Bulletin of New York Tuberculosis Association, vol. iii, No. 4. 30 THE PRACTICE OF PEDIATRICS It is also important that something of the applicant’s previous life should be known. One of the most important things to know about an applicant in a large city, and one most difficult for the physician to discover, is the ex- istence of leukorrhea, or vaginal discharge.1 This, however, can usually be discovered by the tactful young mother. Not only should the ideal nursery maid be physically fit, she must be mentally fit as well. For proper mental and physical development children must be entertained and pleasantly employed. An ill-natured, impatient nurse should be forced to seek other employment. It should not be a task for a child’s attendant to play with him. A woman should not be condemned, how- ever, because she fails with any given child. With a child differently situated, with a different temperament, the results may be perfectly satisfactory. The Nursery.—This should be the largest and best ventilated room in the house. In a city home the room may well be located on the third or fourth floor, with a southern exposure. In apartments, quiet, and the possibility of free ventilation and sunlight must be considered in selecting the room. For the sake of quiet the nursery should not communicate with the sleeping-rooms of older children. In placing children in sleeping-rooms or in a nursery, or in estimating the capacity of hospital wards for children, it is to be remembered that at least 1000 cubic feet of air space should be allowed to each child. The floor of the nursery should not be carpeted. A hardwood floor is best. If this is not possible, covering the floor with oil-cloth or lino- leum is always possible. This can be cleaned with a damp cloth every day. A broom should never be used in a nursery. Paint or hard finish on the walls is preferable to paper. There should be at least two win- dows and an open fireplace. If possible, the bath-room should be con- nected with the nursery, to be used not only for bathing the child but as a “changing room.” The child’s napkins should not be changed in a living-room if it can be avoided. It is needless to say that napkins should never be dried in the nursery. Steam heat as ordinarily used today is the least desirable means of heating on account of its uncertainty. In many New York apart- ments of the better class the fires are banked at 10 p. m.; the tem- perature when the child retires is from 70° to 80° F. or more; by 5 or 6 o’clock in the morning a fall to 50° or 60° F. has taken place. Such a change in the temperature, with the tendency of children to kick off the bedclothes, explains many cases of tonsillitis and bronchitis. The tem- perature of the nursery should be kept as even as possible. When for any reason this cannot be controlled, it is best to have two means of heating, so that when one fails the other may be used. The open-grate fire or a small wood-stove is best. Gas should never be employed as a means of heating a child’s sleeping-room on account of the rapid ex- haustion of the oxygen which results. The furniture of the nursery should be of the plainest. Hardwood chairs and tables with enamel or brass cribs or bedsteads should be used. There should be no article of furniture or furnishings in a nursery that 1 A very severe gonorrhea was contracted by one patient from a nursery maid. AIDS TO NUTRITION 31 cannot be washed. In the bath-room or in some adjoining room a pail should be kept containing some disinfectant solution, such as carbolic acid, 1 : 100, or carbonate of soda solution, 1 ounce to 2 gallons of water, in which the napkins are placed as soon as soiled. There should be two shades at each window, a light and a dark one, so that it will be possible to darken the room during the sleeping time, as well as to exclude the early morning light, which is the usual cause of too early waking. Babies should be taught to sleep until at least 6 o’clock in the morning. This is far better for the child and also for the mother if she occupies the same room. The unnecessary habit of an early waking at 4 or 5 o’clock will in most instances readily be broken by keeping the room dark. The nursery should have suitable means for ventilation. For this purpose, aside from the fireplace, the window-board is of no little service (p. 26). There should be a thermometer in every child’s living-room or nursery. It should register from 70° to 72° F. by day and from 65° to 68° F. by night. The nursery should be given an hour’s airing twice a day. The child should sleep in a crib, alone, not with an adult or an older child. The old-fashioned cradle in which generations have been rocked may be an interesting heirloom, but under no circumstances should it be re- moved from its place in the garret. It is realized that the above sug- gestions are not applicable in many homes. Nevertheless, if we aim at the ideal, existing conditions, no matter how unpromising, will invariably be made better. The Nursing-bottle and Nipple.—There are two requirements that a nursing-bottle must fulfil: it must have a capacity sufficient for one full feeding and it must be so constructed as to be readily cleansed. The oval bottle with rounded edges answers best. These may be obtained in sizes of from 3 to 9 ounces. As many bottles are needed as there are feedings in twenty-four hours. The bottles should be boiled once a day, scrubbed with a stiff brush with hot borax water, and remain in the borax water until needed. Two teaspoonfuls of borax to a pint of water is the strength usually used. Before using, bottles should be rinsed in plain boiled water. The straight black nipple is also preferred, for the reason that it can be turned inside out and easily cleansed. A nipple which cannot be turned should never be used. After use the nipple should be turned and scrubbed with a stiff brush and borax water —a tablespoonful of borax to a pint of water. When not in use the nipple should be kept in borax water, and before being placed on the bottle it should be rinsed in boiled water. The nipple should be boiled once a day. The blind nipples—those without holes-—are the best. Holes of the required size may be made with a red-hot cambric needle. For the administration of thick feedings which are not easily intro- duced into the ordinary feeding bottle, the “Hygeia” bottle and nipple have proved satisfactory. The Breck feeder is described on p. 165. Baskets for Early Exercises.—It is a mistake made in many families to have the baby in the arms a greater part of his waking hours. This practice should be discouraged by physicians, for when the child is held 32 THE PRACTICE OF PEDIATRICS there is always a tendency to make him sit upright on the arms or knee without proper support. During the early months of life the vertebrae and vertebral ligaments are not sufficiently developed to support the heavy head and trunk. If this thoughtlessness on the part of parents with its attendant dangers were explained, there would be fewer cases of displaced scapulae and spinal curvature to be treated later. Many cases of spinal curvature are the direct outcome of such early abuse of the spinal col- umn. Still, it is not desirable that the infant should constantly occupy the crib. A large clothes-basket in which a thick blanket and pillow have been placed affords a safe playground for a small baby. For the first few months he will lie on his back and amuse himself in his own pecu- liar way. After the sixth month, when he may be allowed to sit up for a short time each day, a pillow should be placed behind his back for support. The basket supplies plenty of room for toys and other means Fig. 1.—Scoop and platform scale. of entertainment. When the child begins to stand and attempts to walk the basket period is at an end and the exercise pen (p. 839) or screened “coop” should be brought into use. Scales.—A scale for weighing the baby is a very necessary adjunct to the nursery furnishings. There are several varieties of scales on the market known as “baby scales.” Their usual construction provides for a basket for holding the baby, the basket being supported by a steel rod which rests upon a spring. A needle indicates on a dial the weight of the child. This variety of scale is very unsatisfactory: it gets out of order easily, it is expensive, and with a vigorous, kicking child, the rapid oscillation of the needle makes an accurate reading of the weight difficult if not impossible. Further, the weight capacity of these scales is but 20 pounds. When the child’s weight reaches this figure it necessitates the purchase of another scale. The scoop and platform scales used by grocers (Fig. 1) are best. They do not easily get out of order, they WEIGHT 33 weigh correctly from \ ounce to 280 pounds, and, being very simple in construction, they can readily be understood. The infant rests on his back in the scoop during the weighing process; older children stand on the platform. Normal Development weight The average weight of the full-term, newborn infant varies from 6 to 9 pounds. Some are born at term weighing less than 6 pounds, and a few weighing over 9 pounds, but in the great majority the birth weight will be found between these figures. Holt found from a study of the records of three large maternity institutions in New York city as follows: The average weight of 568 females was 7.16 pounds. The average weight of 590 males was 7.55 pounds. Every family which can afford it should have a scale (p. 32) for weighing the baby, for only by regular weighing during infancy and childhood can we gain an accurate knowledge of growth. During the first three days of life there is usually a loss in weight of 9 or 10 ounces, according to Holt’s record, 11 per cent, of the birth weight. After this initial loss, which may be expected, but which does not always occur, a weekly gain in weight is to be looked for, the child regaining the birth weight on the eighth or tenth day. At first it is advisable to weigh twice a week, or even daily, if the child is not progressing satisfactorily. After the second month, when the infant is making satisfactory progress, a weekly weighing will answer, and this should be continued until the child is one year of age. During the second year bimonthly weighings are sufficient. Girls of the same age, after the first year, will average from \ to 1 pound lighter than boys. During the third year monthly weighings will be sufficient to enable one to keep in touch with the child’s condition. During the first six months of life a weekly gain of 4 to 8 ounces has been made by well children. When a child does not make at least an average gain of 4 ounces weekly we do not put him in the “doing well” class, but look into his care and nutrition to learn what is wrong. Children vary in growing capacity. Some will increase in weight rapidly, gaining 4 ounces a day, while others will make a slower gain and yet be perfectly well. Through the care of many children we have come to regard 4 ounces as the minimum weekly gain for a well child. In a well infant the birth weight should be doubled by the fifth or the sixth month, and at one year the weight should be a little over two and one-half times that at birth. During the second year a gain of 5| to 7 pounds will usually result under proper conditions. During the third year from 5 to 6 pounds will be added. It is not to be in- ferred that these are arbitrary figures or that perfectly well children may not be under or above the figures given at the ages mentioned. These figures are, however, to be regarded as the average for the different ages. Suggestions for the memorizing of weight and height figures are offered on p. 41. A weight chart with its colored “normal” line will not be found in this book, and physicians are advised against its use. Time and again one sees well infants, though slow in growth, made ill by overfeeding, 34 THE PRACTICE OF PEDIATRICS in the vain attempts of an ambitious mother or nurse to keep her infant up to the “normal” line. It may be said that the weekly weighing might have similar effect; not so. Here there is nothing for comparison—no normal red line “staring” the mother in the face. The weighing alone is not sufficient to inform us absolutely concern- ing the development of children.

It is often a matter of no little distress to parents that their children are undersized. Short mothers and fathers cannot expect very tall children. If the latter have right care, they will probably be larger than the parents, but cannot be expected to grow as much as playmates whose fathers and mothers are tall. The height bears much less relation to the condition of the child than does the weight. 36 THE PRACTICE OF PEDIATRICS The following table, taken from Holt and Howland,1 gives the figures for weight, height, chest, and head circumference from birth to three years of age: AVERAGE NET WEIGHT, HEIGHT, AND CIRCUMFERENCE OF HEAD AND CHEST OF HEALTHY CHILDREN FROM BIRTH TO THREE YEARS Age.

Wood and published by the Child Health Organization.2 THE HEIGHT AND WEIGHT RATIO The Midpoint of the Body.—At birth the midpoint is above, and at one year just below, the umbilicus. At six years the midpoint is midway between the symphysis and umbilicus, and in adult life at the symphysis. The Head and Chest Circumferences.—The figures for these measure- ments are included in the table above. The development of the head is a good criterion of the growth of the brain which determines the size of the skull. The skull circumference increases about | inch per month during the first half of the first year and j inch per month during the last half of the first year. The chest circumference follows very closely that of the head till the third year, then increases much more rapidly than the growth of the head, the increase in chest circumference averaging 1 inch per year from the first to the fifteenth year. STANDARDS OTHER THAN WEIGHT AND HEIGHT 1 Diseases of Infancy and Childhood, 1923, p. 22. 2 Copyrighted 1918 by Child Health Organization, 156 Fifth Ave., New York. THE TEETH 37 The Abdomen.—The abdominal measurement corresponds closely to that of the chest up to the third year, at which time the measurements of head, chest, and abdomen are all about equal. The Fontanels.—The lateral are closed at birth, the posterior is closed at two to four months, and the anterior at about eighteen months. At one year the diameter of the anterior fontanel is normally about 1 inch. The Blood.—The composition of the blood presents marked differences dependent upon age. The characteristics of greatest significance in the blood of infancy are mentioned on page 430. The Gastric Capacity.—The anatomic capacity is the actual holding volume of the stomach as determined by the measurement of water poured in postmortem at a pressure of 15 cm. The physiologic capacity represents what an infant can take and retain at a nursing. By reason of the fact that immediately after its ingestion milk begins to leave the stomach and pass into the intestine the rule that physiologic capacity is greater than anatomic capacity is readily explained. Figures representing the anatomic capacity as determined postmor- tem by Holt are in part as follows: Birth 1.2 ounces 4 weeks 2.0 “ 8 weeks 3.37 “ 12 weeks 4.5 “ 6 months 5.75 “ Mosenthal,1 in a study of 24 cases, found that an amount of 3.6 ounces was ingested at a nursing when the anatomic gastric capacity (determined postmortem) was only 2.6 ounces. THE TEETH Twenty teeth comprise the first set. In the well child the first tooth usually appears between the sixth and the eighth months; the first teeth may, however, in perfectly normal cases, come earlier or much later. A perfectly well, vigorous child may not show a tooth until the thirteenth month. The first teeth are usually the two lower central incisors. The four upper incisors and the two lower lateral incisors appear normally between the eighth and the tenth months. The first four molars appear between the twelfth and the fifteenth months; the four canines between the eighteenth and the twenty-fourth months; the four posterior molars, which complete the first set, between the twenty-fourth and the thirtieth months. This regularity in the appearance of the teeth is by no means constant, even in well children. Repeatedly one sees the upper central incisors cut first. Rarely the upper lateral incisors have appeared first. In delayed dentition in rachitis and other forms of malnutrition the teeth are very apt to appear irregularly. In a markedly rachitic dis- pensary patient the bicuspids were the first teeth cut. The 'permanent set consists of 32 teeth. The second dentition begins about the sixth year, and is usually completed about the twentieth year, although it may be delayed several years. The permanent teeth appear in somewhat the following order: 1Arch. Ped., 1909, xxvi, 761. 38 THE PRACTICE OF PEDIATRICS First molars sixth year Central incisors sixth to seventh year Lateral incisors seventh to eighth year First bicuspids ninth to tenth year Second bicuspids ninth to tenth year Canines eleventh to twelfth year Second molars thirteenth to fifteenth year Third molars after the eighteenth year Care of the Teeth.—As soon as the teeth appear they require at- tention. Until the second year is reached the mouth should be cleansed at least twice a day with a solution of boric acid—f ounce to a pint of water. This can best be done by means of absorbent cotton wound around the tip of a clean index-finger and afterward dipped in the solu- tion, which should be applied with gentle friction to the gums and teeth. When a child is two years old it is well to begin the use of a soft tooth- brush and a simple tooth-powder composed of the following ingredients: Precipitated chalk 5j Bicarbonate of soda 3j Oil of wintergreen .. q. s. The child should also be instructed as to the proper use of a quill toothpick. The teeth of every child over two years of age should be examined by a dentist every six months. Cavities discovered in the first teeth should be filled with a soft filling. The milk teeth are lost between the sixth and the eighth years. They should not decay, but fall out or be forced out by the second set. The Calcification of the Teeth.—This begins in utero. The normal progress of calcification is most important if the permanent teeth are to present no hypoplasia or deficiency of enamel. In a consideration of the teeth in rickets, Dick1 has clearly shown by diagram the steps by which calcification proceeds and the effects of hypoplasia of enamel due to rickets, as exhibited in the permanent set. Of this set the central and lateral incisors, the canines and the first molars, undergo comparatively advanced calcification in the first two years of life. Consequently these teeth in late childhood show the extensive inroads of a possibly forgotten rickets which has conformed to the fairly constant law of incidence and greatest activity between the ages of six months and two years. (See page 123.) SPECIAL MENTAL AND PHYSICAL DEVELOPMENT IN THE INFANT Dr. Frederick Peterson,2 of New York, made an exhaustive study of the mental development of the newborn. In all, 1060 newborn infants were examined, the observations ex- tending for one year. His observations, which are to be looked upon as authentic, are as follows: “1. Sight.—Sensibility to light is present in most infants at birth, and this is the case even in those prematurely born. The optic nerve 1 J. Lawson Dick, Rickets, 1922. 2 Bulletin, Lying-in Hospital, December, 1910. SPECIAL MENTAL AND PHYSICAL DEVELOPMENT IN THE INFANT 39 is, therefore, already prepared to receive impressions, sometimes even before the time of normal birth. “2. Hearing.—Sensibility to sound is quite as apparent as sensibility to light at birth, for 276 normal white children reacted to sound on the first day of life and 146 reacted to light. A similar condition existed among the premature infants, many reacting to sound on the first day as well as to light. The auditory nerve is already prepared to receive impressions of sound sometimes before the period of normal birth. This is wholly contrary to the opinions of other authorities. “3. Taste.—The gustatory nerve not only reacts differently to salt, Sweet, bitter, and sour at birth, but the same mimetic reactions are ob- served in premature infants. This nerve is, therefore, ready to receive taste impressions some time before the normal period of birth. “4. Smell.—T 'wo hundred and seven normal white children reacted to odors on the first day of birth, and similar reactions were observed in premature infants. The olfactory nerve is ready to receive smell impressions some time before the end of the normal period of gestation. “5. Cutaneous Sensibility.—Reactions to touch and temperature and affective manifestations of discomfort, obtained the first day in large numbers of normal infants, were similarly obtained in premature infants, showing that such sensibility is already present before the ex- piration of the period of normal gestation. There is every reason to believe that sensitiveness to painful stimuli is present, but the reactions are more vague and uncertain than in later life, which leads many to assume that the sense of pain is dull in the newborn. Muscular sense cannot be tested in infants, but there is every reason to believe that muscular sense, the sense of motion, and sense of position are developed early in utero. "6. Thirst-hunger and Organic Sensation.—The newborn child frequently reacts to thirst-hunger on the first day, though the actual need of food is seldom apparent until after the first or second day. Dis- comfort is clearly marked when nourishment is not forthcoming. The cries of discomfort and pain are marked in the first day in full-term infants and noteworthy in the premature. “7. The Beginning of Memory, Feeling, and Consciousness in the Newborn Child.—There are good grounds for believing that the new- born child comes to the world already with a small store of experiences and associated feelings and shadowy consciousness. The fact that even in premature infants we find the senses already prepared for the recep- tion of impressions on the five senses is some evidence of such impres- sions having been already received and stored up in the dim storehouse of a memory already begun. It may even be that some sort of vague light impressions have been received, for it is possible that in the interior of the body the alternation of day and night may in a mild degree be manifested. The transillumination of the hands before a candle, of the skull and face bones by examination of the frontal sinuses and antrum with electric lights, are evidences of a certain amount of translueency of the whole organism to sunlight, which is so much more powerful than any artificial light. There is greater possibility in the matter of the auditory sense, that it may be stimulated by sounds within the body of the mother (by bone conduction possibly)—such sounds as the beats 40 THE PRACTICE OF PEDIATRICS of the maternal and fetal hearts, the uterine and funic souffles, and the bruit of the maternal aorta. “Moderate stimulation of the gustatory nerve is thought to occur through the common swallowing of amniotic fluid by the fetus. “A marked development of receptivity in the senses of touch and of muscular sense during uterine life is undisputed. Movements begin considerably before the sixteenth week of pregnancy, and increase in character and extent from that time on. Often they are so violent as to be painful to the mother. The activity of the muscles and constant contact of various parts of the fetal body with the uterine walls for a period of months before birth must lay a foundation under the threshold of consciousness for a sense of equilibrium and vague spatial relations. The material basis of consciousness is prepared long before birth. “There is already a feeling tone associated with the earliest reactions, though we are altogether in the dark as regards its psychophysiology. The process has been thus formulated: Stimulus—reaction—liking— reinforcement. Stimulus—reaction—dislike or pain—inhibition. This is the early simple associative memory in reactions to stimuli. “8. There are no perceptible differences in reactions of colored and white children or between pairs of twins. “Ability to Hold the Head Erect.—This may be acquired at the third month. Few infants, however, are able fully to support the head before the fifth month. Not a few perfectly normal infants will not be able to support the head before the ninth month. “Sitting Erect.—The ability to sit erect unsupported is acquired be- tween the sixth and eighth months. “Standing.—Many infants will stand with simply hand support at the tenth month. Exceptionally well-developed infants will stand with the hands resting on some object at the eighth month. A remarkable infant under my observation could stand at the fifth month, and walked alone at the eighth month. The average infant walks alone from the fourteenth to the sixteenth month. A few will be able to walk unsup- ported before this period, and other normal children will not walk alone before the eighteenth or twentieth month. “Laughing.—Many infants may be made to laugh from the third to the sixth week. “Memory.—The infant’s memory is very short. I have repeatedly known infants eighteen months of age who have entirely forgotten the mother in a week. “Speech.—Intelligible words are formed at about the twelfth month. From the eighteenth month to the second year two or three words will be intelligently put together.” Sleep and Crying.—These are physiologic phenomena exhibiting vari- ations dependent on growth of the finer senses and muscular powers and belong to the criteria indicating normal development. Their consideration has already been taken up (p. 28). MEMORIZING FACTS PERTAINING TO GROWTH AND DEVELOPMENT 41 SUGGESTIONS FOR MEMORIZING FACTS PERTAINING TO GROWTH AND DEVELOPMENT If proper allowance be made for minor inaccuracies which reference to the standards given will readily correct, the multiplication table of the number 7 may be used as an association link in fixing many of the figures of growth and development in the reader’s mind: 7 equals the approximate weight in pounds at birth, the approximate month of life when the infant sits up and when he cuts his first tooth, the approximate year of life when he enters upon his second dentition. 7X2 equals 14, the approximate circumference in inches of the head and chest at birth and the number of the month when walking is un- assisted. 7X3 equals 21, the approximate length in inches of the body at birth, the approximate weight figure for one year, the number of the month when the anterior fontanel is closed, and a little more than the cir- cumference of head, chest, and abdomen at three years. 7X4 equal 28, the approximate weight in pounds at two years and the height in inches at one year. 7X7 equals 49, the figure for both weight and height at seven years. In addition, it is easy to remember that the ordinary child doubles his weight at five months and trebles it at one year, and that the weight increase from two to seven years ranges between 4 and 5 pounds per year. II. INFANT FEEDING Maternal Nursing THE PROBLEM Writers on this subject are very prone to state that the ability of the mother, particularly among the well-to-do, to fulfil this most important function is surely decreasing. Although this may have been a true state- ment twenty years ago, at the present time it is undoubtedly erroneous. That the young mother of today is better able to nurse her offspring than was her sister fifteen or twenty years ago is, moreover, explained by the fact that the youth of the present day are more vigorous, more nearly normal individuals than were those of an earlier date. The inability adequately to perform the nursing function has always been attributed to the mother ipse. This belief, too, is in error. A child born with a generally enfeebled vitality keenly feels any slight abnor- mality in the milk, or may not be able to digest perfectly normal milk; in either event, the milk disagrees and the nursing is discontinued. Breast milk during the first two or three weeks of the infant’s life is produced under unfavorable conditions which do not indicate the possibilities of the breast as a secreting organ, and early nursing, following as it does upon the stress of confinement, is not indicative of what may be possible later when the customary life and daily habits are resumed. Repeatedly a very high fat or a high protein, or both, have been shown to be entirely corrected after the first week or two without interference. This condi- tion at the time was considered sufficiently serious to warrant the dis- continuance of nursing on the part of a weakly infant, while in a vigorous infant it would be entirely ignored. The change which enables more mothers successfully to nurse their infants is due to two causes—more vigorous fathers and mothers and more vigorous offspring. The more normal the mother, the better able is she to perform this normal function. That this is the case is due with- out doubt to the fact that growing girls and young women are leading more hygienic lives than formerly. The making of golf, bicycle and horseback riding, boating, and automobiling popular and fashionable— in short, the taking of girls out-of-doors and keeping them there a con- siderable portion of the day—has worked a marvelous change for the better, both physically and mentally. Proportionate to the population, ■there are fewer neurasthenics among the young women today than there were twenty years ago, and there will be still fewer twenty years hence, because at the present time the timid, retiring young woman of the neu- rasthenic type is not popular in her set. It is very fortunate for the future of the human race, at least for that portion which resides in the United States, that the young woman has thus transferred her allegiance from the crochet and embroidery needle to out-of-door sports, for a neurotic mother makes the poorest possible milk producer. 42 THE PROBLEM 43 While it may be said that our argument holds only with the wealthy or the well-to-do, nevertheless imitation is one of the strongest charac- teristics of the human race, and this tendency in America to outdoor hygienic living pervades all classes. Saturday half-holidays, and the excursions and outings afforded by reduced rates in transportation, are much more popular than they were twenty years ago. Finally, food is better selected and better prepared, owing to increased knowledge on the part of the people as to what constitutes proper nutrition. It may be thought that we have wandered from our subject—maternal nursing—but such is not the case, for conditions which relate even re- motely to this important function demand our respectful consideration. The food and care of the growing girl have the most intimate bearing upon her future life, and if she is to be called upon to perform the most important function of womanhood, she surely has the right to demand that she receive during her girlhood proper preparation, which hereto- fore has too often been denied her. It is not pleasant to criticize physicians, but we venture that the family physician does not, in a great majority of instances, fulfil his function, or extend his field of usefulness to its full capacity, his con- ception of duty too often including only the care of the sick. Unsought advice concerning the feeding and daily habits of a child’s life is usually welcomed and appreciated, for the reason that in almost every instance errors in a child’s management are due to ignorance. Parents, no matter what their station in life, are glad to do what is for the best interests of their children when the reason for certain procedures is made clear. If a thorough and careful physician can have the physical direction of 10 average girls in any station in life, provided they have the benefit of fresh air and good food from infancy to adolescence, he may confidently predict that successful nursing mothers will be made out of 8 of them. • Certain rules of life having a direct bearing on nursing thus lead us nearer the ideal and may enable the mother who otherwise could not nurse her child to do so successfully. These requirements, it will be seen, are laid along common sense lines and cause no hardship or mental dis- tress, one of the chief requirements of a nursing woman being that she shall be mentally normal. Some mothers will be able to carry on the nursing for only two months; others, three, five, seven, or nine months. After the ninth month it is extremely rare for the breast milk to be sufficient for a child. The most successful nursing age is between the twentieth and thirty- fifth years. Successful nursing carried on by a girl of fourteen, by a woman of fifty-two, and by the much abused society girl has been noted, while it has been seen to fail absolutely in peasant women fresh from the fields of Hungary and Bohemia. Many whose nursing is at first most unsatis- factory develop into perfect nurses. Finally, few functions with which we are called to deal are so variable and uncertain as the production of breast milk. Breast milk is one of the most precious substances. It is invaluable—unless we can put a value on human life. 44 THE PRACTICE OF PEDIATRICS HUMAN MILK While human milk varies as to the proportion of its nutritional ele- ments at different periods of lactation, and even at different times of the day, milks upon which infants thrive agree within certain limits, so that a standard of limitations may be laid down. Among a great many specimens examined the solids have ranged between 12 and 13 per cent. The range in fat has been from 2.75 to 4.65 per cent., protein from 0.9 to 1.8 per cent., sugar from 5.50 to 7.3 per cent. These figures represent the analyses of the breast milks given children who were thriving and who were of different ages. The variations are not as wide as have been reported by others, but it is to be remembered that all these babies were thriving. Whoever has examined breast milk even a few times is aware of the existence of the widest possible variations. One may see breast milks which contain 8 per cent, and others which contain only 0.5 per cent, of fat; but infants thus fed have not been well. Fat exists in mother’s milk as minute globules in emulsion, varying somewhat in composition, depending upon the kind of food eaten. The proteins of breast milk offer a wide field for further study. There are several of these, the most important being casein and lactalbumim The proportions are subject to considerable variation, depending upon the diet and habits of life of the producer. With a continuation of lacta- tion there is a diminution of the protein, so that at the ninth or tenth month the total protein is considerably reduced, often being not over 1 per cent. The sugar content varies less than does either the fat or protein, its range of limitation, even in milk otherwise poor, being rarely over 2 per cent. Examination of Human Milk.—Milk of the mother is usually ex- amined to determine whether it contains a sufficient amount of fat, sugar, and protein to nourish the infant; or to determine whether the quantity of one or more of the nutritional factors is excessive or deficient. Micro- scopic examination shows us little except the presence of colostrum, which usually disappears about the ninth day and is to be considered abnormal if present after the twelfth day. The presence of blood and pus may also be detected by the microscope. For an accurate analysis the milk should be sent to a laboratory properly equipped for such work. For absolute accuracy it is not safe to judge from the analysis of one specimen of milk; at least two, better three, specimens should be analyzed before coming to a conclusion. In collecting milk for examination the middle of a nursing should be selected. Laboratory analysis is expensive, however, and beyond the possi- bilities of many. For out-patient work and those cases in which a deter- mination of approximate percentages is sufficient the Holt milk set is of great service. The set consists of a lactometer and two cream gages. The method of its use as explained by Holt is as follows: Fat Determination.—“The simplest method is by the cream gage. Its results are only approximate, but in most cases sufficiently accurate for clinical purposes. The tube, filled to the zero mark with fresh milk, stands, corked, at room temperature for twenty-four hours, when the BREAST FEEDING 45 percentage of cream is read off. The ratio of this to the fat is approxi- mately 5 to 3; thus 5 per cent, cream indicates 3 per cent fat, etc.” “For an accurate determination the best method is the Babcock test, which requires 20 c.c. of milk, or the modification by Lewi of the Leffman and Beam test for cow’s milk. This requires special tubes.” Sugar Determination.—There is no accurate clinical method for deter- mining the amount of sugar; only a chemical analysis is reliable. How- ever, the sugar varies less in different milks than do the fat and protein and its variations are of much less importance clinically. Protein Estimation.—“Clinical methods for the estimation of the protein are not very satisfactory. We may form some idea of the protein from a knowledge of the specific gravity and the percentage of fat if we regard the sugar and salts as constant, or so nearly so as not to affect the specific gravity. We may thus determine whether it is greatly in excess or very low, which, after all, is the important fact. The specific gravity will then vary directly with the proportion of protein, and inversely with the pro- portion of fat, i. e., high protein, high specific gravity; high fat, low specific gravity.” By subtracting the sum of the percentage of fat and the estimated sugar and ash percentages from that of the total solids a fair calculation of the percentage of protein in a given sample of milk may be made. For accurate estimation the method of Van Slyke and Bosworth1 may be used to determine the casein percentage which multiplied by 1.4 gives with sufficient accuracy the total protein percentage. “A specimen taken for examination should be either the middle portion of the milk—i. e., after nursing two or three minutes—or, better, the entire quantity from one breast. The first milk is slightly richer in pro- tein and much poorer in fat. The last drawn from the breasts is lower in protein and much higher in fat. The following analyses from Forster illustrate these differences”: First portion, Second portion, Third portion, per cent,. per cent. per cent. Fat 1.71 2.77 5.51 Protein 1.13 0.94 0.71 Fundamental Rules.—The following may be laid down as nursing axioms: A diet similar to what the mother was accustomed to before the ad- vent of motherhood should be taken. There should be one bowel evacuation daily. From three to four hours daily should be spent in the open air in exercise which does not fatigue. At least eight hours out of every twenty-four should be given to sleep. There should be absolute regularity in nursing. There should be no worry and no excitement. The mother should be temperate in all things. BREAST FEEDING 1 New York Med. Jour., 1909, xc, 542. 46 THE PRACTICE OF PEDIATRICS In addition to these fundamental axioms certain rules applicable to the details of nursing should be remembered. Twenty minutes is the maximum time during which a baby should be allowed to remain at the breast. In most instances the twenty minutes is too long. (See Rate of Milk Secretion, p. 49.) On no account should the infant be allowed to sleep at the breast. The three-hour interval between feedings is best in most instances, at least until the completion of the third or fourth month. One breast at a nursing should be given if the milk is plentiful. If the supply is not enough, both breasts may be given at the same feeding period. After the nursing the baby should be held up against the mother’s shoulder and patted gently on the back to allow eructation of air from the stomach. Finally, after the baby has been put down, and before the cleansing of the mother’s nipples, massage of her breasts is desirable as a means of expressing any residual milk and of stimulating the productive activity of the glands. The value of such breast massage in cases of deficient lactation has been repeatedly demonstrated. Early Giving of Water.—From \ to 1 ounce of a 5 per cent, solution of milk-sugar should be given the infant every two hours until the milk appears in the breast. Otherwise there will be unnecessary loss in weight and perhaps a high degree of fever due to inanition. If the baby is restless and uncomfortable, it is safe to conclude that he is thirsty; 1 ounce of the sugar-water will usually satisfy him. With the commencement of nursing he should be accustomed to getting his food at regular intervals. The First Nursing.—Six hours after delivery or confinement the nipples should be washed with a saturated solution of boric acid and the child put to the breast and nursing attempted. After this the at- tempts at nursing should be repeated every four hours, although the milk does not appear in the breasts until from forty-eight to seventy-two hours after the birth. Colostrum may be present. It is useful as a laxa- tive and may satisfy the child. Further advantages of early nursing are that it promotes uterine involution and gradually accustoms both the infant and the mother to what will be required later. Care of the Nipples.—Immediately after the nursing the nipple should be carefully washed with a saturated solution of boric acid and thor- oughly but gently dried. A baby should never be allowed to nurse from a cracked or fissured nipple. For this veiy painful condition a nipple- shield (Fig. 2) should always be used. (See p. 53.) The Diet.—Many times, when consulted by a nursing mother because the nursing was unsuccessful or a partial failure, the physician finds that her diet has been restricted to an extreme degree. To put on a greatly restricted diet a robust young mother who has always eaten bountifully of a generous variety of foods is one of the best means of curtailing the quantity and lowering the quality of her milk supply. When asked to prescribe a diet one may safely tell such mothers to eat as they were accustomed to before the advent of pregnancy and motherhood. That this particular vegetable or that particular fruit should be forbidden on BREAST FEEDING 47 general principles is a fallacy. Food that the patient can digest without inconvenience is a safe food so far as the nursing is concerned, as may readily be determined in any given case. For certain individuals, how- ever, a plain, more or less restricted diet is desirable. This must be remembered in the management of the wet-nurse (p. 56). Many a wet- nurse who has been carefully selected, and who to the best of our judg- ment should prove satisfactory, utterly fails in a few days to fulfil the duties of the office for which she was chosen. In not a few instances the failure is due to a very full diet of unusual articles of food, the ex- istence of which, in many instances, she never dreamed of. Indigestion and constipation follow, both the nurse and the baby are made ill, and the woman’s usefulness ceases. A woman who has lived and kept well on the diet and food found in the home of the laboring man, whether in the city or country, will make a far better wet-nurse on this diet than if she indulges in food to which she is entirely unaccustomed. In gen- eral, the diet of a nursing mother, then, should be that to which she has been accustomed. Nursing is a perfectly normal function, and a woman should be permitted to carry it out along only natural lines. Inasmuch as there are two lives to be provided for instead of one, more food, par- ticularly of a liquid character, may be taken than the mother may have been accustomed to. It is customary to advise that milk be given freely. A glass of milk may be taken in the middle of the afternoon and 8 ounces of milk with 8 ounces of oatmeal or cornmeal gruel at bedtime, if it does not disagree with the patient. Our only evidence that a food is not disagreeing is the condition of the digestion. When any article of food disagrees with the mother, or if she is convinced that it disagrees, whether or not such is really the case, the food should be discontinued. In a general way, milk in quantities not over one quart daily, eggs, meat, fish, poultry, cereals, green vegetables, and stewed fruit constitute a basis for selection. The method of preparation of the different meals is not arbitrary. The Bowel Function.—A very important and often neglected matter in relation to nursing is the condition of the bowels. There must be one free evacuation daily. For the treatment of constipation in nursing women different methods have been tried in many cases. The dietetic treatment does not promise much. For here, again, manipulation of the diet may interfere with the milk production. Three methods are open to use—massage, local measures, and drugs. Massage is available in comparatively few cases. Local measures consist in the use of enemas or suppositories. Every nursing woman should use an enema at bedtime Fig. 2.—Nipple-shield. 48 THE PRACTICE OF PEDIATRICS if no evacuation of the bowels has taken place during the previous twenty- four hours. Many out-patients, in whom constipation is a frequent symptom, indulge in excessive tea drinking, often taking from 1 to 2 gallons of tea daily. In treating such patients where an absolute dis- continuance of the tea drinking is often impossible and not absolutely necessary one may allow 2 cups a day. For a laxative in such cases and in many others a capsule of the following composition has served well: 1$. Extracti belladonnse gr. \ Extracti nucis vomicse gr. f Extracti cascara; sagradse gr. v M. et ft. capsula No. i. Sig.—To be taken at bedtime. The amount of the cascara sagrada may be varied as the case may require. In not a few instances it will be found necessary to give two capsules a day in order to produce the desired result. Neither the bella- donna, the nux vomica, nor the cascara appears to have any appreciable effect on the child. Air and Exercise.—Outdoor life and exercise are not only as desir- able here as they are under all other conditions, but to the nursing woman, with her added responsibility, they are doubly valuable. In order to get the best results exercise or work should so be adjusted as not to reach the point of fatigue. The mother whose nights are disturbed should be given the benefit of a midday rest of an hour or two. She should have at least eight hours’ sleep out of every twenty-four. Certain annoyances, anxieties, and worries are inseparable from the life of every child-bearing woman. It should be our duty, however, to explain to the mother and to other members of the family that an important element in satisfactory nursing is a tranquil mind. During the lactation period she should be spared all unnecessary care and petty annoyances. Regularity in Nursing.—The breast which is emptied at definite in- tervals invariably functionates better than does one which is not, not only as regards the quantity but also the quality, of the milk; so that system in breast feeding is almost as essential to milk production as to its digestion and assimilation. After it is demonstrated that the nursing is progressing satisfactorily, as proved by the satisfied, thriving child, it is well to begin with one bottle feeding daily. The advisability of this is obvious: in case of illness of the mother, if she is called away from home, or if, for any reason, the child cannot have the breast, the feeding is provided for. Another advantage of this provision is that it gives the mother needed freedom from re- straint. She is thus enabled to have the benefit of a change of scene. Amusements and recreations which the invariable nursing period denies her can be indulged in. As a result of this greater freedom she is able to supply better milk and to continue nursing longer than if tied con- tinually to the baby, no matter how fond of the infant she may be. Frequency of Nursing.—From birth until the third month seven nursings in twenty-four hours are allowed as follows: 6 and 9 a. m., 12 m., 3 and 6 p. m., and 2 a. m. From the third to the completion of the six month, six nursings, as follows: 6 and 9 a. m., 12 m., 3, 6, and 10 BREAST FEEDING 49 p. m. After the sixth month, and in large strong children after the fifth month, five nursings in twenty-four hours, as follows: 6 and 10 a. m., 2, 6, and 10 p. m. Determination of the Milk Supply.—Whether or not the child is getting a sufficient quantity of milk may be determined by weighing the baby before and after nursing. For this purpose the scales used for weighing children should weigh accurately in half-ounces. The child, who need not be undressed, should be weighed when put to the breast and weighed at the completion of the nursing. Repeatedly one will find that an infant who should get 3 ounces or more at a feeding during the fifteen- minute nursing increases in weight but | to 1 ounce, showing that only so much milk has been taken. Occasionally cases have been seen which showed no gain whatever after nursing and yet the child was sup- posed to have been fed. In the event of difficult breast feeding it is well for the physician personally to supervise a nursing or two, for by this means much valuable information may be gained. The Rate of Milk Secretion.—After a study of the rate of secretion of breast milk in a group of cases at Bellevue Hospital, Smith and Merritt1 stated that nursing infants obtain from 40 to 60 per cent, of their supply in the first two minutes and from 60 to 85 per cent, in the first four min- utes, only the larger, vigorous infants nursing from an abundant supply getting milk up to sixteen minutes. These observers concluded “A baby who needs both breasts may nurse from six to eight minutes on the first and from five to seven on the second. Very few babies need as long as ten minutes on a breast. A good many will empty the breast in four or five minutes.” Signs of Successful Nursing.—The normal infant shows a gain of not less than 4 ounces weekly. This is the minimum weekly gain which may safely be allowed. When a nursing baby remains stationary in weight or makes a gain of but 2 or 3 ounces a week, something is wrong, and the defect will usually, but not invariably, be found in the milk supply. When the baby is nursed at proper intervals and the supply of milk is ample and of good quality, he is satisfied at the com- pletion of the nursing. Under three months of age he falls asleep after ten or twenty minutes at the breast. When the nursing period again approaches, he becomes restless and unhappy, crying lustily if the nursing is delayed. When the breast is offered, he takes it greedily. The stools are yellow and number from two to three daily. The weekly gain in weight under such conditions is usually from 6 to 8 ounces. Signs and Causes of Unsuccessful Nursing.—Theoretically, every normal breast infant should be a thriving, well baby. That the standard established for a well baby is not upheld is unfortunate. When the supply of milk is scanty the child remains long at the breast, cries when he is removed, and shows signs of hunger before the nursing hour arrives. A cause of failure in breast feeding, and probably the most frequent cause, is a scanty milk supply. The chief nutritional elements in mother’s milk are: fat, 3 to 4 per cent.; sugar, 7 per cent.; protein, 1.5 per cent. Failure may be due to a marked disproportion of these elements, which may cause sufficient 1 The Rate of Secretion of Breast Milk, Amer. Jour. Dis. Child., November, 1922. 50 THE PRACTICE OF PEDIATRICS indigestion and resulting loss in weight to necessitate a discontinuance of nursing. Thus there may be a high fat—from 5 to 6 per cent.; or very low fat—from 1 to 1.5 per cent. In the high fat cases there is usually diarrhea with green, watery stools. The child strains a great deal and there are green stains on many of the napkins. In high fat cases there is also regurgitation or vomiting of sour material. The fat globules may readily be made out if the vomited material is placed under a low-power microscope. Low fat means deficient nourishment and may cause con- stipation. Sugar is rarely a cause of trouble in nursing babies. It seldom varies, ranging from 5 to 7 per cent, in the great majority of breast milks. Young children, further, have a marked toleration for sugar. The protein of mother’s milk is a most frequent cause of nursing diffi- culties. Like the fat, the protein may be so decreased that nutritional disorder may be induced in the patient, or it may be very much increased, the latter condition being usually the cause of colic or constipation in otherwise healthy nursing infants. In such cases curds may be found in the stools, the passage of which is always accompanied by a great deal of gas. The milk may contain the normal percentage of fat, sugar, and protein, but be scanty in amount. Instead of the 4 or 5 ounces to which the child is entitled, he may get but 1 or 2 ounces. Whether or not the quantity is sufficient may be determined by weighing the baby before and after each nursing for twenty-four hours. One ounce of breast milk weighs practically 1 ounce avoirdupois. The quality or strength is determined by an examination of the milk itself (p. 44). The quantity is determined by noting the weight of the child, wearing the same clothing, before and after nursing. By nursing for fifteen min- utes a child under one week old should gain from 1 to 1| ounces; at three weeks of age, 1J to 2 ounces; four to eight weeks of age, 2 to 3 ounces; eight to sixteen weeks of age, 3 to 4 ounces; sixteen to twenty-four weeks of age, 4 to 6 ounces; six to nine months of age, 6 to 8 ounces; nine to twelve months of age, 8 to 9 ounces. Of course, arbitrary limits cannot be fixed as to the quantity. Stationary weight or loss in weight, with a dissatisfied child, usually means a deficiency of milk, which is readily proved by the weighing. To be fed at the breast may also cause the child to suffer from an excess of good milk, in which event there will be vomiting or regurgitation, usually associated with colic. When this overfeeding continues, dilata- tion of the stomach develops, vomiting becomes habitual, the child loses in weight, the breast milk is said not to agree, and often, unfortunately, the baby is weaned. This has been the outcome in scores of cases. When there is habitual vomiting and colic in a nursing baby, two things are to be done—the baby must be weighed before and after nursing, and the milk must be examined. Repeatedly children treated for indigestion have been entirely relieved by shortening the nursing period. Weighing the baby at intervals of from three to five minutes and noting the gain has shown that the 3 or 4 ounces which may represent the child’s stomach capacity were obtained in two, three, or five minutes, the excess which the child took over this amount being the cause of his trouble. From a free, full breast a vig- BREAST FEEDING 51 orous nurser will take one ounce in one minute. When the nursing “gait” is established, a child should be kept up to the schedule. There are few more pernicious teachings than that a baby should be allowed to nurse when he wants to and as long as he wants to. In fact, the idea that a nursing infant will take no more than is good for him is the fruit of in- experience. Illustrative Case.—A mother sought advice regarding giving her one-month-old baby the bottle, as he had many green stools, cried a great part of his waking hours, and weighed but a few ounces more than at birth. Her milk was supposed to be “too strong” for the child. An examination of the breast and a talk with the mother indi- cated that the breast milk was not at fault. An examination of the milk proved it to be good average milk, containing 3.5 per cent, fat., 6 per cent, sugar, 1.45 per cent, protein. A one day’s test by weighing was instituted. The infant was allowed to nurse one minute and rest one minute. During the resting period he was weighed. In this way it was found that in three minutes he got from 3 to 3| ounces of milk. The nursing was then reduced to three minutes on one breast and five minutes on the other, which was the “slower” breast. Thereupon every sign of indigestion promptly disappeared, the stools became normal, and the infant made a satisfactory gain in weight of 1 ounce daily. The quantity may be suitable for the age, the child may not vomit or show a sign of indigestion, and yet may not thrive. In such a case an examination or repeated examinations of the milk at intervals of two or three days will usually show that it is poor, below the normal perhaps in both fat and protein. Illustrative Case.—A Swedish woman was admitted to the New York Infant Asylum with an infant two months old in fair condition. The woman had an abundance of milk and asked for a foster-child, so great was her discomfort from the excessive flow of milk. The weekly weighings of the children soon revealed that there was no growth, and after a few weeks both children upon examination showed developing rickets. The milk was then examined and was found deficient—fat, 1.2 per cent.; sugar, 5 per cent., and protein, 0.73 per cent. Signs of Insufficient Nursing—The baby remains long at the breast, perhaps one-half to three-quarters of an hour. When removed he is restless and uncomfortable. After a short time, in an hour or less, he is very hungry and demands frequent nursings day and night. Conditions Which May Temporarily Produce an Unfavorable Effect Upon the Breast Milk, but Not Necessitate the Discontinuance of Nurs- ing.—The advent of the first menstruation period particularly, and in some cases the beginning of every menstruation period, is attended with an attack of colic or indigestion in the child. Such attacks, however, rarely necessitate the discontinuance of the nursing even for a single day. Factors influencing the mental condition of the mother, such as anger, fright, worry, shock, distress, sorrow, or the witnessing of an accident, may affect the milk secretion sufficiently to cause no little discomfort to the child, and often lessening of the flow for a day or two. Illustrative Case.—In the County Branch of the New York Infant Asylum there were at one time about 200 nursing mothers, the majority of them from the lower walks of life, at least 95 per cent, of the infants being illegitimate. The necessity of placing a considerable number of these mothers in wards, in close social contact, gave rise to rather frequent disputes, and not infrequently to fistic encounters of a decidedly vigor- ous character. After a particularly active disturbance, several nursing infants in the ward would become suddenly ill, usually with vomiting, diarrhea, and fever. One 52 THE PRACTICE OF PEDIATRICS soon learned to know the cause when inquiry or hasty inspection showed that the mothers of those who were ill had been particularly active in the dispute. A small proportion of the mothers were from the better walks of life. Letters of forgiveness or reproach or visits of a like nature from fathers, mothers, or sisters have brought many a sick baby to attention and caused many anxious moments. Conditions Which Call for Temporary Discontinuance of Nursing.— During an acute illness with fever, such as indigestion, tonsillitis, and minor illnesses of a like nature, nursing should be discontinued for a day or two. During this period it should be our effort to maintain the flow of the milk. This is best done by emptying the breast with a breast- pump (p. 54) at the usual nursing period until the time arrives when the nursing may be resumed. In such conditions the advantage of having the baby accustomed to one bottle a day will at once be appreciated. Management of Abnormal Milk Conditions.—When it is found that the breast milk is too strong or too weak, or when the normal ratio of fat, sugar, and protein is not maintained, it may be possible to increase or diminish the milk strength. When desirable, it may also be possible to increase either the fat or the protein. The heavy milk will usually be found in mothers who are robust, who eat heartily, and who take but little exercise. In such a case the prescribing of a plain diet, allow- ing red meat but once a day, discontinuing the malt liquors or wine— which it will often be found that the mother is taking—and directing that she walk a mile or two a day, will frequently bring the milk to di- gestible proportions. In some cases, however, this will not be successful, and the colic, constipation, and vomiting may continue, even though the quantity obtained at each nursing is within normal limits. In some instances it will be impossible to change the mode of the mother’s life, except perhaps in the discontinuance of alcohol. When such conditions prevail, the milk may be modified by giving from 5 to 1 ounce of boiled water or plain barley-water before each nursing. One teaspoon- ful of lime-water added to 1 ounce of water before each nursing has made the breast milk agree when otherwise breast feeding would have been impossible. When the milk is deficient both in fat and protein, a diet composed largely of red meat, poultry, fish, rye bread, or whole-wheat bread, oatmeal, cornmeal, with 2 or 3 pints of milk daily, will often be followed by an increase both in fat and protein. The use of alcohol in moderate amounts, in the form of malt liquors or wine, will often in- crease the fat 2 per cent, in from two to three days. Disappointments in improving the quantity or quality of the breast milk, however, are frequent. In general, it may be stated that if a mother has been getting adequate nourishment in appropriate form to satisfy her desire, the pos- sibility of improving her breast milk by measures such as those just out- lined is by no means as good as in the case of a poorly nourished, under- fed woman. In addition to the one bottle which, for reasons above mentioned, is given early in the child’s life, it is necessary at the seventh month to add an extra bottle or two. Usually at this time the protein in human milk begins to diminish in quantity, and as this is the most important nutritional element, an insufficient quantity at this rapidly growing period of life is of no little importance. At the twelfth month, with very BREAST FEEDING 53 few exceptions, exclusive breast feeding, if one consider the best interests of the child, is practically out of the question. Out of many thousands of cases we recall but one instance when a mother was able successfully to nurse her child after the twelfth month. This remarkable woman, a mother of 6 children, had nursed every one of them exclusively up to the fifteenth or the eighteenth month. Management of Abnormal Breast Conditions.—Cracked and Fissured Nipples.—Fissures of the nipples often result from lack of care and cleanliness. Nipples that are not washed and dried, but allowed to re- main moist after nursing, particularly during the first few days, are also very apt to become macerated and cracked. In the cases in which there is a tendency for the breasts to “leak,” the milk decomposes on the nipples, and the nipple becomes actually excoriated by the acids formed by the decomposition in the milk. Leaking nipples should be kept covered with pads of sterile absorbent gauze. Cracks and fissures in the nipple may be sufficiently painful to prevent a continuance of the nursing. In getting the histories of not a few bottle babies one is told that nursing has been stopped because of cracked nipples. A strong child tugging on a fissured nipple may occasion excruciating pain to the mother, and when the fissures are not healed, it can readily be understood that such pain and the dread of nursing may produce sufficient mental distress to change the character or stop the flow of the milk, either of which con- ditions may require that the nursing be discontinued. The prevention and successful treatment of the condition, therefore, is a matter of no little importance. The treatment which gives the best results, and which has been in use at the New York Nursery and Children’s Hospital, is to bathe the parts with a saturated solution of boric acid after each nursing, dry the nipple, and apply a pad of sterile gauze. Once or twice a day the cracks or fissures are painted with an 8 per cent, solution of silver nitrate. There is no pain attending this application. The pad of sterile gauze is placed over the nipple and held in position by a binder sufficiently tight to sup- port the breasts. Before the nursing the nipple is bathed with sterile water and the infant takes the breast as usual. If there are deep fissures, it may be well for a day or two to use a nipple-shield (Fig. 2). The use of a light lead nipple-shield between nursings, particularly at night, has given good results in some cases, presumably from the formation of lactate of lead by contact of the shield with the moist nipple. Cleansing is essential after the use of this device. The use of an ointment on the nipples is not advised, for the reason that it is of little or no service, and in most cases ointments do actual harm because they soften the epithe- lium and make the nipple tender. Diminishing the number of nursings to three daily has been of use in some severe cases which were slow of response to treatment. Removing the child from the breast entirely is to be advised only under conditions of much urgency, as the milk may be entirely lost as a result of protracted absence of this stimulation to the breast. Another important reason for securing rapid healing is the danger of infection through the open nipple wound, the usual cause of mammary abscess. 54 THE PRACTICE OF PEDIATRICS Depressed Nipples.—Not an infrequent source of difficulty in the management of the nursing function in a primipara are depressed nipples. The child cannot get a sufficient hold to make suction possible. He thus fails to get the desired nutriment, and, in consequence, both the child and the mother become exhausted. When this is repeated a few times, the child is very apt to refuse to make any attempt at nursing. In such cases the use of the nipple-shield is often indispensable until the nipple is sufficiently drawn out and developed for the child to get hold of. Pre- ceding each nursing it is well to manipulate the nipple for a few minutes or to elongate it by the use of the breast-pump (Fig. 3), without using sufficient force to draw the milk. Caking of the Breasts.-— Induration of the breasts is of very frequent occurrence during the first few days of nursing. The milk, when it ap- pears in the breasts, is often secreted in large amount. A great deal more is supplied than the child, with his small stomach and usually in- different nursing, is able to digest. The breasts should therefore be watched very carefully during this time so as to guard against the possibility of the milk remaining undrawn. After the completion of the regular nurs- Fig. 3.—English breast-pump. ing, if a considerable amount of milk remains in the breasts, it should be drawn by the breast-pump and the breast thus relieved. Caking is frequently the outcome of fissured nipples. Sucking on the part of the child, the use of the breast-pump, and hard pressure in milking are all very painful procedures, with the result that the milk remains undrawn. When nodules form, they may readily be softened by gentle mas- sage. Lanolin should be used on the fingers so as to avoid unnecessary irritation of the skin. The massage should be repeated as often as the nodules appear. The caking is more apt to occur in the dependent por- tion of the glands. The so-called pendulous breasts, which may show a tendency to cake, should be supported by a binder tightly applied. Acute and Suppurative Mastitis.—When inflammation of the breast develops with fever, chills, and prostration, it is usually the result of an infection through the nipple, generally one with visible cracks and fissures. For our purposes the different varieties of mastitis need not be considered. Nursing of the involved breast should be discontinued for the sake of both the child and the mother; in fact, the pain is often so great that nursing is impossible. A supporting bandage should be applied and WEANING 55 the milk drawn with the breast-pump at the usual nursing times. It must be our aim to induce resolution without the formation of pus. This is best accomplished by the use of an ice-bag which is applied to the inflamed, indurated area. If there is a tendency to constipation, saline laxatives should be used. In fact, the patient will often be benefited not a little by two or three watery evacuations daily. With a subsidence of the temperature and an abatement of the inflammation, nursing may be resumed. As soon as the presence of pus is determined, it should be removed regardless of its location in the gland. Many cases of intestinal infection in the infant, and of infectious processes in other parts of the body, have undoubtedly been due to nursing from suppurating breasts. Mixed Feeding.—With a diminution in the amount of milk secreted, the breast milk must, of course, be supplemented by modified cow’s milk. This method of feeding is usually successful. If the mother of a six-month-old baby can satisfactorily nurse him three times in twenty- four hours, he may be given, in addition, three bottle feedings, supple- menting the mother’s milk. It is best when using mixed feedings to alternate the breast and the bottle. The modified milk strength should be that which is suitable for the average child of the same age. (See General Rules, p. 73.) In beginning the use of cow’s milk, however, it must be remembered that at first a weaker strength must be used than the child will require for growth, this weaker food being necessary in order gradually to accustom the infant to the change. If too strong a cow’s milk mixture is given at first, it will be very apt to disagree, causing colic and vomiting. Later, when the child has become accus- tomed to the new food, a stronger mixture may be given. When a mother cannot give her infant at least two satisfactory breast feedings daily, it is advisable to wean the child. Maternal Conditions Under Which Nursing is Forbidden.—When the mother has tuberculosis in any of its various forms or manifesta- tions, whether it involves the glands, the joints, or the lungs, breast feeding is to be forbidden. In epilepsy and syphilis nursing is likewise forbidden. In nephritis and malignant disease of any nature, and in chorea, nursing should be discontinued. Women who are rapidly losing- weight should not be allowed to continue nursing their infants. In most cases of serious illness, such as typhoid fever, pneumonia, or diphtheria, and upon the advent of pregnancy, nursing should be terminated. It is the consensus of opinion of many authorities that when the mother is suffering from a mild attack of one of the infectious diseases, including pertussis, diphtheria, and scarlet fever, nursing may still be permitted. This rule does not apply in severe cases. Nursing babies rarely contract contagious disease from their mothers because the milk secretion undoubtedly conveys immunity.1 WEANING When is the nursing baby to be given other food, or how long can the breast be relied upon to furnish the sole nourishment? If the mother, unassisted, is able to nourish her infant completely for seven months, she 1 Hartshorn, Maternal Nursings, New York Med. Jour., July 6, 1912. 56 THE PRACTICE OF PEDIATRICS is doing remarkably well. There are very few nursing mothers who can pass that period without assistance. Perhaps one or two bottle feedings a day may suffice. In many cases the milk will fail about the seventh month, and absolute weaning be necessary. Granting, however, that the child is thriving on the breast alone, or doing satisfactorily on the breast with only two daily feedings, at what age should the weaning take place? Just one mother out of several thousand came under our observation who could nurse her child to the child’s advantage after twelve months had passed. Many pronounced cases of malnutrition, rickets, indigestion, and diarrhea have been the outcome of prolonged breast feeding. The weaning in health should begin not later than the twelfth month, and in many instances it would be to the advantage of the child if nursing were interrupted earlier. Weaning is best accomplished gradually by substituting bottle feeding for nursing, giving only one bottle the first day, two the second, three the third, and so on until in a week or ten days weaning is complete. , In case the child is ill we may be obliged to wean at once by substituting bottle feeding for the breast, but the milk formula corresponding to his age should not be given. A baby six months of age should receive the three-month formula; an infant nine months of age should receive the six-month formula. A gradual increase to the formula suggested for a child the age of the patient may be made if all goes well. After the ninth month it is often possible to feed from a cup, which is then to be preferred to bottle feeding as a substitute for the breast. It is best not to attempt weaning during the hot months unless the conditions demanding it are urgent. Care of the Breasts During Weaning.—When the breast feeding is carried on the usual length of time—from nine to twelve months— the process of weaning ordinarily causes little or no discomfort. All that is usually required is to press out enough of the milk to relieve the patient as often as the breast becomes painful, which may not be Aiore than two or three times a day. When the weaning is necessarily abrupt, no little discomfort may result. If there is a free flow of milk, which is apt to be the case when the weaning must take place in the early nurs- ing period, tightly bandaging the breasts is required. When localized hardened areas occur in the glands, they should be massaged until soft- ened, and the bandage reapplied and worn until the secretion ceases. When the weaning can be accomplished more gradually, the infant should have one less nursing every second or third day until only two are given daily. After this has been practised for one week nursing can be dis- continued. In cases where sudden weaning is required, a saline laxative, such as citrate of magnesia or Rochelle salts, should be given every day for five days—sufficient to produce two or three watery evacuations daily. In the meantime the mother should abstain from fluids of all kinds up to the point of positive discomfort. THE WET-NURSE We are called upon to select a wet-nurse under various conditions. A few families, particularly those who have had disastrous feeding ex- THE WET-NURSE 57 periences, ask that no attempts at artificial feeding be made, but that a wet-nurse be engaged in advance of the confinement so as to be ready when the time for her service arrives. Usually, however, our minds and those of the parents turn to the wet-nurse when nutrition by other means is a failure. It is well to remember in this connection that it is not wise to postpone our resort to the wet-nurse until every chance of her being of assistance has passed. It may take a few days’ observation or but a single glance at one of these difficult feeding cases to decide whether a wet-nurse must be secured. Certain it is that in a few cases we cannot do without such aid. In the selection of a wet-nurse the age during which nursing is most successfully carried on is to be remembered. As a rule a wet-nurse should not be under twenty-two or over thirty-five years of age. The peasant women of the continent of Europe make the best wet-nurses. A woman should not be selected as a wet-nurse without a thorough ex- amination both of herself and of her infant. She must be free from skin diseases, tuberculosis, and syphilis. Whether she is stout or thin, tall or short, amounts to little. Neither can we place much reliance on the size of her breasts. Although full, firm breasts and prominent nipples are desirable, the best indication as to her nursing ability is the condition of her baby. For this reason it is best not to select a woman before her baby is four weeks old, for by that time his physical condition will indi- cate with considerable accuracy the kind of food he has been getting. The wet-nurse’s milk need not correspond with the age of the patient for whom she is engaged, as breast-milk from the fourth week to the third month of lactation will answer for any infant. The results attending the first few days of wet-nursing are often most disappointing. The radical change which takes place in the nurse’s habits of life, necessitating the leaving of her own child to the care of others, sometimes produces nervous conditions which may have a de- cidedly unfavorable influence upon her milk. Before arriving at the conclusion that she will not answer in a given case she should, there- fore, have time to adjust herself to the changed conditions. Many a good wet-nurse, accustomed to a very plain diet and some work, which necessarily means exercise, has been ruined, so far as her usefulness as a milk producer is concerned, by overindulgence at the table. Upon assuming her new office she is temporarily the most important member of the household next to the baby, and articles of food are supplied to which she is entirely unaccustomed and of which she eats plentifully. The result is an attack of indigestion with fever, the baby is made ill, and the usefulness of the wet-nurse in the family ceases. These women usually do best upon a plain diet of meat, poultry, fish, vegetables, cereals, and milk. If they are accustomed to taking beer, one bottle daily may be permitted. Coffee may be allowed to the extent of one cup daily, and of tea not more than two cups should be allowed. Women of this class are almost invariably neglectful of the bowel function, so that this must be attended to. One free evacuation should take place daily. As a rule, the wet-nurse has been accustomed to work and will be more contented and happy when her time is occupied. If she possess sufficient intelligence to take the baby for outings, she should be allowed to do so. 58 THE PRACTICE OF PEDIATRICS Being out of doors from three to four hours a day is of decided advantage to every nursing woman. For the comfort of the family it is wise not to let a wet-nurse know her full value. Wrhen she feels that she is indis- pensable, trouble is apt to follow. It is particularly necessary, there- fore, that babies who are wet-nursed should be given one bottle feeding daily as soon as they are able to take care of it. The wet-nurse will then realize that she can be dispensed with in case of misconduct, or if she leave with an hour’s notice the child can be given the bottle until another nurse is secured. In the great majority of cases it has not been necessary to continue the wet-nursing after the children are seven months of age, for by this time they can usually be fed on the bottle. Of course, unless her nursing proves unsatisfactory, a wet-nurse should not be dismissed at the commencement of or during the summer. Artificial Feeding THE PROBLEM A considerable number of the young of the human race are deprived of the natural means of nutrition, the milk of the mother. For com- paratively few is a wet-nurse available. While in proportion to the children born more mothers are nursing their infants now than formerly, nevertheless every year thousands of infants are brought into the world who have to be nourished by other means than human milk. The fact that an immense number of deaths occur every year among these infants because of defective nutrition speaks for itself. Nutritional Errors.—Mortality statistics give a very inadequate idea as to the part played by nutritional errors in the young, for the reason that in many instances such errors are not the direct or immediate cause of death, and for this reason their influence does not appear in mortality statistics. As elsewhere pointed out, and dwelt upon at length in this work, in disease of any nature a child’s resistance is a factor of para- mount importance. With defective nutrition resistance is invariably below the normal. Many of the infants who die from the intestinal diseases of summer, from grip, from tuberculosis, or from infectious diseases, suffer from defective nutrition in different degrees of severity before the immediate cause of death exists. The Needs of the Patient Paramount.—As nutrition deals directly with questions of life and death, it is not surprising that volumes have been written on the subject, but it is surprising that the fundamental principles of infants’ nutrition are so little understood. This is due in part to the fact that writers and teachers of infant feeding, in their efforts to be scientific or ultrascientific, have lost sight of the point that there is a patient as well as a pupil to be considered, and that not a few teachers with their algebraic or otherwise intricate formulas do little but obstruct the progress of rational feeding by making a readily comprehended sub- ject impossible to many. Another common error is in not distinguishing between children—the rich and the poor, the sick and the well. A baby with malnutrition, with marasmus, or with temporarily disordered di- gestion is by no means well, and when he is given food suitable only for the well, his condition very naturally is not improved. SCIENTIFIC INFANT FEEDING 59 Environment.—In feeding an infant, several predominant factors must be considered: First, the influences of environment. The infant in a children’s institution has to be fed differently from one who comes to a dispensary for treatment, and both must be fed differently in summer than in winter. The child of well-to-do, intelligent parents is fed still differently. There are no hard-and-fast rules in infant feeding other than that there must be an ample supply of such nourishment as the child can digest and thrive upon. Cow’s milk is used as the basis of infant’s food, for the reason that it is ordinarily readily adapted to the child’s digestion and is the most available substitute for human milk. Successful Artificial Feeding.—Successful substitute feeding of in- fants consists, then, in giving something upon which the child can live and thrive, and when, in addition, this “something” supplies the nutri- tion which nature demands, it constitutes scientific infant food, what- ever the source of the nutriment. Cow’s milk is just as fully an unnatural food for an infant as is barley or rice gruel or the milk of the goat or the ass; and cow’s milk only is used, as already mentioned, because in a great majority of cases it answers the given purpose better than does any other food, in that it furnishes in available form the nearest approach to the nutritional elements required.' SCIENTIFIC INFANT FEEDING The senior author was recently taken to task by a young colleague for using evaporated milk, malt soup, dextrimaltose, and various flours, such as barley and Imperial Granum, in feeding difficult cases. It was unscientific to use these substances, the argument maintained, because the human breast did not elaborate evaporated milk, malt soup, barley flour, or dextrimaltose. Instead of such substances, fresh cow’s milk, lime-water, milk-sugar (Squibb’s), and boiled water should be employed. The writer replied that he had used the substances enumerated daily for twenty-five years and had fed several thousands of infants on fresh cow’s milk, milk-sugar, and lime-water; while in experience with many nursing mothers in institutions and in private work he could not recall a single instance wherein the human breast had secreted fresh cow’s milk, lime- water, or Squibb’s milk-sugar. Scientific infant feeding consists in supplying a balanced ration of fat, protein, carbohydrate, and mineral salts in an assimilable form upon which the infant makes normal development. Neither the fat, protein, nor car- bohydrate must be of one invariable form. Nature permits of a wide latitude. In function, moreover, the fat and carbohydrate are interchangeable and may vary widely in nature and in quantity. There must, however, be a fairly definite content of protein of a nature that admits of its util- ization; or we shall have varying degrees of malnutrition and marasmus; for without nitrogen and other protein constituents cell growth is impos- sible. By the use of starch and alkalis, the subjection of milk to the influence of heat of varying degrees, and by other means, we may change the nature of the protein to such an extent that the infant may utilize the food in a manner before impossible. 60 THE PRACTICE OF PEDIATRICS An immense amount has been learned concerning infant feeding dur- ing the past twenty-five years. Our scientific attainments, however, will be much greater after a few more decades, and even then the last word will not have been spoken. COW'S MILK As cow’s milk furnishes the most available basis of nutrition for the infant who is deprived of the mother’s milk, it is essential in order to secure the best results from its use as an infant food, that it contain total solids between 12 and 13 per cent, and that the solids be represented in the nutritional elements in somewhat the following proportions: Fat 3.5 to 4 per cent. Sugar 4 to 4.5 Total protein 3.5 to 4 Ash 0.7 to 0.9 “ Specific gravity 1.028 to 1.033 In order that the milk may be of a fairly constant strength, herd milk is to be preferred to the product of one or two cows, as the quality of the latter may vary considerably from day to day. It has been dem- onstrated that the best cows for this purpose are what are known as “grade cows,” that is, not pure bred. Such cows thrive better, are more easily kept healthy, and are more uniform in the nutritional equivalent of their milk supply than are high-class registered herds of the Alderney or Jersey strain. Milks necessarily differ in composition. The feeding of the cows and their care particularly influence the quality of the milk. The per- centages given indicate approximately its nutritional value and are sufficiently accurate for, purposes of feeding. The Fat.—This ingredient of milk is in the form of a fine emulsion and separates as cream. Its character is affected by the cow’s food, being soft- ened when some articles are fed and hardened when other kinds of food are used. The fatty acids exist in a proportion about six times as great in cow’s milk as in human milk. Furthermore, the emulsion of fat droplets is not so fine in cow’s milk as in breast milk. These are two important facts explanatory of the ability of a nursling to digest 4 per cent, fat in breast milk when he may be incompetent to digest over 1.5 per cent, fat from cow’s milk. In the stomach the fat becomes entangled in the casein curds and under- goes very little digestion, leaving the stomach last of all the food elements, and, if given in too large amount even inhibiting to some degree gastric motility. In the intestines emulsification and saponification of the fatty acids into which the fats are split takes place in the medium of alkaline bile. The soaps on absorption are acted upon by the epithelium of the intestine and yield neutral fat which is taken up by the thoracic duct and eventually the blood. Rapid fat excretion is the rule in diarrhea. If, however, excessive fat in the intestine can be brought into combination with alkalies to form calcium soaps, constipation may result. These &re only a few of the considerations one must weigh in ap- proaching the problem of fat per cent, determination for the given case. The Sugar.—Ordinarily lactose is used because it is the sugar present cow’s MILK 61 in breast milk. Because of the lower lactose content in cow’s milk, an amount ranging from 6 to 4 per cent, must be added to modified milk feedings as the infant gradually increases his feeding capacity, in order to approximate the 7 per cent, sugar content of breast milk. As the whole milk proportion in the formula is raised, less sugar need be added. After absorption the sugar element circulates in part in the blood in con- centration of 0.1 per cent, and is stored as glycogen not only in the liver but also in the muscles. Reference to the selection of the individual sugars for different feed- ing requirements has already been made (pp. 20, 21). The Protein.—In breast milk two-thirds of the protein is available in the form of soluble lactalbumin, whereas in cow’s milk six-sevenths is in the form of casein, a kind of protein hard to digest and relatively poor in the essential amino-acid, cystin. This accounts for the relative ease with which the infant thrives on breast milk containing 1.25 per cent, protein, whereas, 1.75 to 2.50 per cent, protein is required from cow’s milk to provide him with equivalent nitrogenous material neces- sary for growth. In terms of cow’s milk 1| to If grams of protein is con- sidered a fair allowance per pound of body weight, and since cow’s milk contains 1 gram of protein per ounce we derive the simple feeding rule that protein requirements are fully met in terms of cow’s milk by about If ounces per pound of body weight. The problem of modifying the casein to insure easy digestibility has been attacked in various ways to be described later. Examination of Cow’s Milk.—In the use of cow’s milk, as in that of human milk, a chemical analysis is necessary in order to know accurately the nutritional elements. The specific gravity varies from 1.029 to 1.035. Milk is acid in reaction to phenolphthalein, and may be neutral to lit- mus. The Babcock milk-test machine is what is generally employed in examining cow’s milk in laboratories and institutions. The test con- sists in mixing the milk with strong sulphuric acid, which dissolves the proteins and liberates the fat, the quantity of which is read off from the graduated neck of the bottle used in mixing the milk and acid. Only the fat is determined in this way. Knowing the fat and the specific gravity, one may readily determine the solids other than fat by adding to one-fourth of the specific gravity, reading to the right of the decimal point, one-fourth of the percentage of fat. Differences Between Human and Bovine Milks.—The following comparison has been made by Morse and Talbot.1 Human milk. Cow’s milk. Fat 4.00 4.00 Sugar Protein 7.00 4.75 1.50 3.50 Salt 0.20 0.70 “Both are amphoteric in reaction when they leave the breast. Cow’s milk is usually acid when it reaches the baby. Human milk is practically sterile as the baby takes it. Cow’s milk, even under the best conditions, is far from sterile when the baby gets it. The emulsion of the fat is much finer in human milk than in cow’s milk. The proportion of fatty acids 1 Diseases of Nutrition and Infant Feeding, 1915, p. 182. 62 THE PRACTICE OF PEDIATRICS is much higher in cow’s milk than in human milk. A large proportion of the protein in human milk is in the form of whey protein. A large pro- portion of the protein in cow’s milk is in the form of casein. Human milk is not coagulated by commercial rennin, cow’s milk is coagulated. Both are coagulated by human rennin. The enzymes of the two milks are different and each milk has a specific serum reaction. “It is evident, therefore, that no matter how cow’s milk is modified, it will still be different from human milk. The percentages of the differ- ent food elements can be made the same. The difference in the protein can be corrected by the use of whey. The emulsion and the composition of the fat will, however, always be different. The ferments can never be made the same and the specific serum cannot be changed.” Bacteriology of Cow’s Milk.—Milk fresh from the udder contains very few bacteria, particularly if the first two or three jets from each teat are discarded. The time for bacterial contamination is during the milking and while the milk remains in the stable. Certain forms of bac- teria are harmless, and it is impossible to have a milk absolutely free from bacteria. What we need to know is how dangerous bacteria get into the milk, and how they cause changes that may convert it into a poison of greater or less virulence. Harmless Bacteria.—The souring of milk is the result of the presence of bacteria, which produce changes in the sugar of milk, with the forma- tion of lactic acid. Of these, Bacillus acidi lactici and Streptococcus lac- ticus are the common forms. The “turning” of milk during a thunder- shower is due to certain changes in the atmosphere that aid in the devel- opment of the bacteria which convert lactose into lactic acid. Harmful Bacteria.—Bacteria of decomposition, under conditions favorable to their growth, attack the protein constituents of the milk, producing putrefactive changes with evolution of poisons which may be of the greatest virulence. The putrefactive bacteria are always present in stables where manure is allowed to collect and where cleanliness is not observed. When we remember what a culture-field milk affords to bac- teria, and when we see the manure and the surroundings in which milk is usually drawn, it is not surprising that the milk should contain many millions of bacteria to a cubic centimeter. They may enter the milk from the dust in the stable—a very fruitful source—or they may find entrance from the milker’s hands or from droppings of fine particles of manure from the belly of the cow. Bacteria from these sources are among the most dangerous forms found in milk. Among diseases readily transmitted through contaminated milk are to be mentioned tuberculosis, typhoid fever, scarlet fever, diphtheria, and septic sore throat. The organisms of dysentery, cowpox, hydrophobia, actinomycosis, foot-and-mouth disease, the staphylococcus, gas bacillus, colon bacillus, cholera bacillus, and anthrax bacillus are all at times found in milk. Market Milk.—The legal standards for pure milk in most instances relate only to the chemical composition of the milk. The laws of most of the States call for 12 per cent, of total solids, and at least 3 per cent, of fat. If the milk contains less than these percentages it is considered impure, even if it is just as it was when it left the cow’s udder. Some cow’s MILK 63 cows give milk considerably below this standard. The chemical anal- ysis of milk does not show whether it is suitable for use as an infant food, this point being decided according to its freshness and the care with which it has been handled with reference to the exclusion of bacteria and the prevention of their growth. The production of clean, safe milk is expensive without allowing anything for the labor of caring for the cows. The milk must be carried to the consumer, which is also expensive. Yet, in New York City milk that satisfies the legal requirements retails in the grocery stores, during the summer months, at 10 or 12 cents a quart. This milk is known as “grocery milk,” or loose milk, and is a very poor food for infants. It is teeming with bacteria, as little care is taken in its preservation. The next grade of milk is sold in quart bottles which have been filled in the country, packed in cracked ice, and shipped to the city. The milk contains many bacteria, but is far better than grocery milk. It is retailed to the consumer in two grades, at a difference of about 3 cents in cost. Grade A milk must contain not over 30,000; and Grade B, not over 100,000 bacteria per cubic centimeter. Certified Milk.—The best grade of milk, and the one which should be used in feeding infants whenever possible, is known as “certified milk,” and is produced under the direction of what is known as a “milk com- mission.” The establishing of “milk commissions” in different cities throughout the country has been the means of securing a much better milk supply than was formerly possible, and has unquestionably been instrumental in saving thousands of lives. To Dr. H. L. Coit, of New- ark, N. J., is due the credit of organizing the first milk commission. Certified milk must conform to certain standards as to its nutritional value and as to the number of bacteria per cubic centimeter. These standards are established by a committee of medical men who compose the milk commission, and who have complete control of the dairy and its entire output. The Milk Commission of the New York County Medical Society requires a standard of milk not containing over 10,000 bacteria in a cubic centimeter. When a dairyman has shown to the satisfaction of the Com- mission that he can produce a milk up to the required standard, he is allowed to attach to his bottles labels certifying to that fact. Milk thus “certified” is taken from the delivery wagon from time to time and sub- jected to examination by their bacteriologist in order to determine whether it conforms to the requirements of the Commission. Certified milk, furthermore, must contain an average of 4 per cent, butter fat and must be obtained from tuberculin-tested, tuberculosis-free cows. A study of the details that must be observed in the production of such milk is most instructive and gives insight into the best methods of dairy management. Suffice it, however, to state that certified milk con- taining fewer than 5000 bacteria per cubic centimeter is now a common commodity and is obtainable by a steadily increasing number of families. Sterilization and Pasteurization of Milk.—The sterilization and pas- teurization of milk, as the terms imply, are for purposes of preservation. The term sterilized milk is applied to milk that is heated to the boiling- point and maintained at that temperature—212° F.—for twenty min- 64 THE PRACTICE OF PEDIATRICS utes. The effect of sterilization is the destruction of the pathogenic bac- teria, but it will not destroy the spores. Dr. R. G. Freeman’s observations show that heating the milk to 140° F. and maintaining it at this point for one hour is of advantage, in that the bactericidal effects are as good as when a higher temperature is used. At the same time the lower tempera- ture produces less chemical change in the milk. Pasteurization consists in heating the milk to 167° F., main- taining it at that temperature for thirty minutes, and then quickly cool- ing it. The effect of sterilization and the rapid cooling is to kill the existing bacteria, thus preventing, temporarily, further bacterial growth in the milk. The milk which is boiled in a bot- tle which is properly covered is “ster- ilized milk,” but if the sterilization is to be carried on day after day an Arnold sterilizer (Fig. 4) should be used. For purposes of pasteurization the Freeman pasteurizer (Fig. 5) is recommended. Pasteurization makes Fig. 4.—Arnold sterilizer. Fig. 5.—Freeman pasteurizer. less change in the character of the milk content; consequently, there is less interference with its nutritive value. The temperature, too, 167° F., is sufficiently high to destroy pathogenic bacteria, including Bacterium cow’s MILK 65 lactis aerogenes, and hence acts as a valuable preservative, particularly during hot weather. Pasteurization Safest for Exclusive Use.—The question, whether milk should be given sterilized, pasteurized, or raw has given rise to endless discussion in the press and in medical societies. Each method has its advocates. Among the pediatrists at the present time some contend that milk should be sterilized, regardless of the season of the year, the character of the milk, or the station in life of the patient; others main- tain that invariably it should be given raw, regardless of the above- mentioned conditions; while still others are devoted to pasteurization. If any of the methods were to be used exclusively, pasteurization, being the safest, should be selected. Judging from varied experience in the matter of the heating of milk for infant foods, the subject should be considered from a broad standpoint. There is no one way of heating milk that is invariably the best. There are several factors which determine which is the proper procedure in a given case. Raw Milk Preferred if Fresh and Pure.—There is no doubt what- ever that the less the milk is heated, the better food it is for the average well baby, provided it is clean when procured and can be kept clean and sweet until it is used. (See Cow’s Milk, p. 60.) This is possible in some of our dairies of the better class; it is possible with many who live in the country, or who go to the country for the summer and who keep their own cows or who get their milk supply from a neighboring source which they can control. Under such conditions the milk may be given raw during the entire year. When, however, the milk has to be shipped a considerable distance during the summer, when its safety depends upon the industry and carefulness of the employees of a milk farm, pasteurization is advisable during the heated term. Sterilized milk is rarely used among our private patients except during an ocean journey (see Milk for Traveling, p. 96) or a long-distance journey by land. For hospital out-patients the fol- lowing scheme is the safest: From May 1st until October 1st the milk is boiled (sterilized). These people, most of them, cannot afford a pasteurizer or sterilizer or understand the use of either. From October 1st to May 1st the milk is given raw. Pasteurization would be preferable, but it is possible with but very few dispensary patients. Even the giving of cooked milk, which unquestionably often becomes contaminated after cooking, is at- tended with no little risk to the child, as is shown by the death records of bottle babies during the summer. The giving of the cheap market milk raw to infants of the tenements during the heated term in any large city can only help to increase the mortality of this season. The object of heating the milk should always be explained to the mother so that she may appreciate the necessity of keeping it carefully covered and properly caring for it afterward. The idea is prevalent among uninformed people that after sterilization but little further pro- tection is required. When one is satisfied the out-patients have not the requisite intelligence nor the means for keeping cow’s milk during the summer, such as an ice-box and ice, he may discontinue the ordinary milk feeding for the hot months and use evaporated milk instead (p. 78). 66 THE PRACTICE OF PEDIATRICS Cream.—Market creams are known as “gravity cream” and “centrif- ugal cream.” Gravity cream is obtained by allowing the milk to stand for a certain length of time and then removing the cream. When milk, as soon as it is drawn, is placed in a quart milk bottle or fruit jar and kept at a tem- perature of between 40° and 50° F., most of the fat will have risen at the end of five hours. When the cream is carefully removed at the end of this time, from 0.3 to 0.8 per cent, of fat will remain in the milk. The fat content of gravity cream is subject to considerable variation, depend- ing, of course, upon the richness of the milk and the manner in which it is treated, particularly as relates to rapid cooling. In cream from well-kept grade cows the fat will average about 16 per cent. In cream from well-fed Alderney or Jersey herds it may be as high as 20 per cent, or higher. In cream from cows indifferently fed, or those which subsist entirely upon poor pasturage, the fat may be as low as 10 or 12 per cent. For infant feeding gravity cream from the milk of grade cows is preferred. In using cream for infant feeding all the cream to the milk line should be removed, as the upper layers are much richer in fat than that adjoining the milk. Further, when cream is mixed with milk both must be of the same age, as the addition of older, bacteria-laden cream to fresh milk will surely result in grave digestive disorders. Centrifugal cream is that which is removed by an apparatus known as a separator, which consists of a circular bowl for holding the milk, so arranged as to make from 3000 to 5000 revolutions a minute. This results in a rapid separation of the lighter fat from the milk. The fat collects near the center of the bowl and is removed by a device arranged for this purpose. The skimmed milk flows outward from another portion of the bowl by a similar device. Centrifugal cream is more difficult of digestion than gravity cream, in that the natural emulsion in which the fat is held in the milk is destroyed by the process of centrifuging. Centrifugal cream may vary greatly in its fat content, depending upon the rapidity of opera- tion of the separator. According to Babcock and Russell the proteins also undergo a change which does not add to their nutritive value. The skimmed milk derived in the manner described contains a remnant of 0.5 per cent. fat. THE ADAPTATION OF COW'S MILK At one time it was thought that, by changing the percentage com- position of cow’s milk and altering the reaction, it could be made prac- tically identical with human milk, and the term “modified milk” was applied to cow’s milk so manipulated. A great variety of manipula- tions of cow’s milk has been introduced, which often differ greatly in the principles involved. Yet to products of all these different manip- ulations the term “modified milk” is applied. It may mean any one of a dozen or more different products. Cow’s milk diluted with water and given as a food to an infant is called “modified milk.” When sugar, cereal gruel, lime-water, bicarbonate of sodium, or citrate of sodium is added, the mixture is still “modified milk.” When a prescription is sent to the laboratory calling for definite amounts of fat, sugar, and protein the product furnished is “modified milk.” When a mother is THE ADAPTATION OF COW’S MILK 67 told to use a definite amount of cream, milk, sugar, and water, “modi- fied milk” is also the outcome. As a matter of fact, successful infant feeding consists in what should be termed “milk adaptation,” that is, modifying the milk to suit the case in hand. The routine prescriber is content to prescribe “modified milk” which is a simple imitation of human milk. The best-informed prescriber uses “an adapted modified milk.” The Percentage Standard.—To Rotch, of Boston, we are indebted for the establishment of the practice of thinking in percentages in the feeding of infants. The method based on the fact that the proportion of fat, sugar, and protein in average breast milk as fairly indicative of the needs of the normal infant, is employed as a means of varying formulae for individual patients. Working with cream and skimmed milk each of known composition one may add varying amounts of milk-sugar and construct mixtures of any desired composition. Slight increase or diminution in any of the different elements may also be made with control over the rearrangement of the proportions of the constituents. Sufficient variation in the percentages of the protein and fat for prac- tical feeding purposes may be similarly obtained by diluting top milk from different levels after the natural separation of cream on standing. Formulae illustrative of this point are to be found on pp. 70, 71. To reduce any given formula to the percentages of its constituents one may simply multiply the percentage of the respective elements in the original undiluted milk by the proportion of the milk in the total formula. For example, a formula containing 10 ounces of milk of the com- position fat 5 per cent., protein 3.50, and sugar 4.50, with water up to 30 ounces, will without the addition of the usual supplementary sugar contain 10/30 of each of the percentages given for each ingredient, i. e., 1.66 per cent, fat, 1.16 per cent, protein, and 1.5 percent, sugar. Adding 1§ ounces of sugar to the 30-ounce mixture will increase the sugar content by 5 per cent., thus making the total sugar percentage 6.5. The practice of thinking in percentages is easy to acquire and of un- doubted value. The Calorimetric Standard.—In brief, the calorimetric standard is based upon the amount of energy indicated in calories for each pound of body weight. A calorie is the amount of heat required to raise the tem- perature of 1 liter of water 1° C. Heubner, of Berlin, several years ago began the employment of cal- orimetric principles in infant feeding. His original observations, which were made on healthy breast-fed infants, weighed before and after each feeding, showed that under six months 100 calories were required daily for every kilogram of body weight. After the sixth month, the number of calories required gradually lessened, so that at the completion of one year about 85 calories to each kilogram of body weight appeared to be necessary. Lamb1 reduced Heubner’s figures to pounds. He gave the calorimetric requirements during the first three months of life as 45 calories daily per pound of body weight, during the next three months from 40 to 45 calories 1 Archives of Pediatrics. June, 1908. 68 THE PRACTICE OF PEDIATRICS daily per pound, decreasing gradually during the next six months, so that at the twelfth month from 32 to 35 calories daily per pound of body weight are necessary. Heubner’s observations, upon which the standard is based, were made on thriving breast babies. In order to judge of its practical value in arti- ficial feeding the histories of 33 bottle-fed infants were selected at ran- dom, from office files, for investigation. It was found that every child was getting food of greater caloric value than the standard called for. All but 2 required food in caloric value exceeding 100, as set by the standard. The daily consumption of 31 of these splendidly thriving infants, all of whom continued to do well, was from 140 to 360 calories in excess of the Heubner standard. Only 33 histories were investigated. Hundreds of records are available showing the same result. The calorimetric standard is thus a means of little utility in infant feeding. It may aid as a check to excessive feeding of very young and delicate infants. Infants whom we see—and they differ not at all from the average infants in this country—cannot be fed successfully by this method alone. As the factors of absorption, body length, surface area, and rate of metabolism are studied the limitations of the application of the calori- metric standard to infant feeding are being better understood. (See pp. 22-24.) Milk Modification.—The analysis of mixed dairy milk shows it to contain approximately: 4.0 per cent. fat. 4.0 per cent, sugar. 3.5 per cent, total protein. Human milk contains approximately: 4.0 per cent. fat. 7.0 per cent, sugar. 1.5 per cent, total protein. The first aim in the modification is to make the chief nutritional elements in the food prepared from cow’s milk correspond grossly to the nutritional elements in the human milk. The protein must be reduced, the sugar increased, and the fat reduced even slightly below that usually found in mother’s milk, as the child’s digestive capacity for cow’s milk fat is less by from 15 to 25 per cent, than it is for human milk. The 'protein element in an infant’s food is its chief nutritional content. This has to be reduced to approximately the proportions that exist in human milk, and the change can be accomplished only by dilution. The diluent may be plain water or it may be a cereal gruel. If 8 ounces of milk is mixed with 8 ounces of water, we get a pint mixture with an approximate nutritional equivalent of: 2.0 per cent. fat. 2.0 per cent, sugar. 1.75 per cent, total protein. If 4 ounces of milk is mixed with 12 ounces of water, we have a 16- ounce mixture with an approximate nutritional equivalent of: 1.0 per cent. fat. 1.0 per cent, sugar. 0.9 per cent, total protein. THE ADAPTATION OF COW*S MILK 69 If 6 ounces of milk is mixed with 10 ounces of water, a 16-ounce mixture is produced with an approximate nutritional equivalent of: 1.5 per cent. fat. 1.5 per cent, sugar. 1.3 per cent, total protein. By this simple dilution with water the desired protein content of the food may be arrived at. The Sugar.—For nourishment of an infant, however, the mixture is weak in fat and very weak in sugar. The sugar content is increased by the addition of milk-sugar or cane-sugar. It will be remembered that in human milk there is a sugar content of 7 per cent. The com- bination of full cow’s milk and water as above gives a sugar content of 2 per cent, or less, so that sufficient sugar must be added to make the increase approximately 7 per cent. What is necessary, then, is to in- crease the sugar content 5 per cent. A 1 per cent, sugar and water mix- ture would contain approximately 5 grains of sugar to the ounce. A 6 per cent, sugar mixture would contain 30 grains to the ounce, and as our dealings are with a 16-ounce mixture, we require an addition of 16 times 30 grains of sugar-of-milk, or 480 grains, so that if we direct that a pint mixture contain 6 ounces of a 4-4-3.50 milk, 10 ounces water, 1 ounce milk-sugar, there would be an approximate nutritional equivalent of: 1.5 per cent. fat. 7.5 per cent, sugar. 1.3 per cent, total protein. Or if the mixture were 4 ounces of milk, 12 ounces of water, 1 ounce of milk-sugar, there would be an approximate nutritional equivalent of: 1.0 per cent. fat. 7.0 per cent, sugar. 0.9 per cent, total protein. It is convenient to remember that 1 ounce of sugar added to any 20- ounce mixture increases the sugar content 5 per cent. The Fat.—While a child of from two to four months might thrive on the above formulae, the fat is obviously deficient and must be increased. This may be accomplished by the use of cream. Cream of the same age as the milk should be used. When this method of feeding is carried out, in order to secure a suitable cream, a quart bottle of milk from a mixed herd of grade cows is allowed to stand at a temperature of 40° or 50° F. for five hours, when a cream which has been referred to as gravity cream will be produced of the approximate strength of: 16.0 per cent, butter-fat. 3.2 per cent, sugar. 3.2 per cent, total protein. With milk, cream, and sugar-of-milk food of every possible strength may thus be obtained. This method of milk preparation is more accurate than when top milk mixtures are used, but it has the disadvantage of requiring 2 quarts of milk for the twenty-four-hour feeding period, one to supply the milk 70 THE PRACTICE OF PEDIATRICS and the other the cream, all of which must be removed and mixed before any of it is used in the food. It is unnecessary to go into the details of the cream and milk mixture method. A more satisfactory method of obtaining any desired fat percentage consists in the appropriate dilution of various top milk portions with water. By this procedure after the gravity cream has formed in the manner described a convenient number of ounces supplying the desired fat content for dilution is removed from the top of the quart bottle with a Chapin dipper and the desired fat percentage is obtained usually by the use of a single quart of milk. The fat content of various milk portions from one ordinary quart bottle (provided the milk is allowed to stand at a temperature not over 50° F. for five hours after milking) is as follows: Portion. Fat, per cent. Top 5 ounces 20 Top 10 ounces 10 Top 16 ounces 7 Top 20 ounces 6 Top 25 ounces 5 Bottom 28 ounces 2 Bottom 24 ounces 1 In all of the samples, for purposes of feeding, the pro- tein and sugar content may be considered the same as in whole milk. By using the appropriate top milk for dilution it is thus possible to vary the fat as desired without ap- preciable change in the protein and sugar percentages selected on the basis of the customary whole milk dilution. For example: A top 12-ounce portion diluted with twice its volume of water may afford a desired 3 per cent. fat. If such dilution reduces the protein content below the percentage desired in a given case the use of a top 16-ounce portion diluted with less water per given volume of milk will supply more protein without exceeding the desired 3 per cent, fat. Top Milk Mixtures.—In adaptation by the use of top milk the milk is first allowed to stand in a quart bottle at a temperature of 45° to 50° F. for five hours. The quantity needed is then removed from the top of the bottle with a Chapin dipper (Fig. 6) and diluted as desired with water or gruel to which sugar-of-milk and lime-water are added. The value of the lime-water will be con- sidered under the “Use of Alkalies and Antacids,” p. 75. The milk selected should be the cleanest obtainable from grade cows; usually the most expensive is the best. From a quart bottle of milk on which the cream has risen, dip from the top with a Chapin dipper 16 ounces and mix. From average milk this should contain: Fig. 6.—Self- filling and empty- ing Chapin dipper, THE ADAPTATION OF COW’S MILK 71 7.0 per cent. fat. 3.2 per cent, sugar. 3.2 per cent, total protein.

After this age two bottles of milk are required, 16 ounces being taken from the top of each bottle and mixed. At this time a cereal jelly is usually added to the food. From the Third to the Fifth Month: Milk (top 16 oz.) 18 ounces Milk-sugar 2 “ Lime-water 3 “ Water to make 40 “ Approximate Percentage Equivalent.

After the fifth month it is desirable to add from 1 to 3 teaspoon- fuls of a cereal jelly to each feeding. This may be added to the milk 72 THE PRACTICE OF PEDIATRICS mixture when it is made in the morning. Thus, if 1 teaspoonful is to be given at each feeding, where a child is getting six feedings, 6 tea- spoonfuls of the jelly may be added to the entire quantity.

Fat 4.3 Sugar 6.5 Total protein 2.0 Five feedings in twenty-four hours; 8 to 9 ounces at each feeding. One ounce = 22.4 calories. After the twelfth month plain undiluted cow’s milk may be given with the cereal jelly in addition to the other articles of diet suggested for a child one year old. (See p. 135.) Considerable latitude is allowed as to the amount of food which may be given at each feeding, because of the difference in the capacity and requirements of individual children. The well child of average size and weight will require daily about 30 ounces of a suitably adapted food at the third month, 30 to 40 ounces at the sixth month, and 40 to 45 ounces at the ninth to the twelfth month. Night Feedings.—After the third month the midnight feeding should be discontinued. Six feedings are sufficient, the first at 6 a. m. and the last at 10 p. m. Between 10 p. m. and 6 a. m. the child should sleep. Babies are easily weaned from the night bottle by substituting a bottle of boiled water or a milk mixture greatly diluted with water. The child soon discovers that this is not worth waking for. As a result of a full night’s rest the digestive organs are better able to do their work, the appetite is increased, and a larger amount of food may be given at each feeding. The Quality of Milk Variable.—It is not claimed that the nutritional value as indicated by the percentage equivalents in the above series is absolutely correct. Milks necessarily differ in composition. Only mixed dairy milk is referred to, the product of several grade cows. The feeding of the cows and their care also influence the quality of the milk. The percentages given indicate approximately the nutritional value and are sufficiently accurate for purposes of supplying satisfactory nutrition to well babies of the various ages. The fat will not be found too low for proper nutrition in any of the formulae given. It may be too high for proper digestion and require adjustment. The proteins as given are sufficient for nutrition if they are assimilated. General Rules for Computing Formulae.—Volumes of set formulae applicable to well and sick babies have been written in the past and the list of top milk feedings above given might easily be supplemented by THE ADAPTATION OF COW’s MILK 73 many more lists, were it not that the tradition for multiplicity of com- putations has been sufficiently upheld by writers in the past. It is only essential for the student to reserve for his guidance certain simple rules. Those presented at the New York College of Physicians and Surgeons may, in part, be cited. (The method employs whole milk dilutions, but is readily extended to the use of top milk of known composition.) The daily fluid requirement of the infant is about 2 ounces per pound weight for the first two weeks, and 3 ounces during the early months, decreasing to 2 ounces again by the end of the first year. The amount of the individual feeding based on the figures for anatomic and physiologic capacity is about | ounce per pound of body weight. The caloric requirement of the average healthy infant during the first two weeks is from 25 to 35 calories per pound, from two weeks to six months 45, and after six months a little less. The protein requirement is fundamental. It ranges from If to If grams per pound of body weight. Since 1 ounce of cow’s milk contains 1 gram, the protein necessary for an infant is supplied by a number of ounces of cow’s milk equivalent to the number of grams of protein indi- cated in a given case. The fat requirement for a normal infant will have been met by an amount contained in the whole milk in about the same proportion as the protein. The sugar requirement ranges from 4 to 7 per cent. To most dilutions of milk for feeding 4 or 5 per cent, of carbohydrate should be added. In writing a feeding formula in terms of a whole milk mixture for a normal infant the rules cited are applicable in detail as follows: 1. Total volume fluid equals the body wreight in pounds X 3 to 2. 2. Number of feedings equals 7, 6, or 5 according to age. „ XT , . , , Total volume of food in ounces1 3. Number of ounces per feeding equals ~r j-?—T. Number of feedings. 4. Total calories needed equals body weight in pounds X 45 to 40. 5. Protein requirement equals body weight X protein of 1| to If ounces of milk. 6. Caloric value of the milk protein equals number of ounces taken X 21 (for convenience, 20). 7. Balance of caloric allotment to be supplied by added carbohydrate equals in Calories required minus calories in milk ounces 1 100 to 120 (depending on caloric value of 1 ounce of the form of carbohydrate used. 8. Volume of diluent equals total volume minus volume of milk portion. Example: Child three and a half months—weight 13 pounds. 1. Total volume = 13 X 2J = 321 oz. 2. Number of feedings = 6 321 3. Ounces per feeding = = (Take 5§.) 4. Calories needed = 13 X 45 = 585. 5. Protein requirement = 13 X If = 22f oz. milk. (Take 23.) 6. Calories in milk = 23 X 21 = 483 (roughly 23 X 20 = 460). „ f x U J 585 - 483 „ 585 - 460 , N 7. Ounces of sugar to be added = - ,)(( = £ oz. (roughly —— — ' oz.) 8. Diluent to be added = 33 — 23 = 10 oz. The formula would therefore read: 23 ounces whole milk. 1 ounce of sugar. 10 ounces of water. 5 5 ounces at each of six feedings. 1 If there is a small fraction in quotient take nearest half-ounce, 74 THE PRACTICE OF PEDIATRICS For undernourished babies a rough guide as to the proper allowance for caloric requirements is the mean between the actual weight of the patient and the weight of a normal infant of the same age. Example: A child at nine months weighs 10 pounds. A normal infant at this age weighs about 18 pounds. The weight figure on which to base food estimation is 14. It has now been shown how by appropriate dilution, and by the ad- dition of sugar the chief nutritional elements in cow’s milk may be made to correspond roughly with those of human milk; the protein being re- duced, the sugar increased, and the fat reduced slightly below that usually found in human milk in order to meet the child’s digestive capacity, which is 15 to 25 per cent, less for cow’s milk fat than for human milk fat. The problem of altering the character of the milk to meet special needs remains to be considered, and this brings us to the details of milk modification. The Effect of Heating Milk Upon Its Assimilation.—Concerning the treatment of milk in order to make it easier of utilization we have much to learn. The milk proteins lend themselves to influences which entirely change their character, and affect their utilization by the infant. The heating of milk influences its digestibility and heating with different substances produces further changes in this respect. As previously stated, evaporated milk is easily and effectively utilized by the infant with a very weak digestive system, and this milk has been subjected to a heating process. When one studies the data available for explanation of the beneficial effects clinically observed as a result of the use of boiled and evaporated milk he meets with disappointment, because the changes demonstrated in milk which has been heated do not all make for its easier digestibility. The mineral salts largely undergo precipitation. The casein is rendered less easy of coagulation by the digestive fluids, but is softer and lighter than in raw milk. The lactalbumin is precipitated and forms a portion of the scum on the surface of the heated milk, which entangles a portion of the fat. The fatty acids are in part volatilized. Prolonged heating may caramelize a portion of the sugar. While the bactericidal effects of heating are in the main beneficial, certain putrefactive spore-bearing organisms may remain after heating and spoil the milk before it turns sour, as it ordinarily does from the action of viable lactic acid organisms before the putrefactive protein changes occur. The antiscorbutic vitamin is destroyed by heating. These, in brief, are the principal changes, their completeness depending largely on the degree and duration of the heat applied. In addition, the boiling of milk with cereal furthers the subdivision of the casein and secures a protective colloid action of undoubted benefit in the digestive canal. Boiled Milk.—A certain child cannot take fresh cow’s milk, modify and adapt it as we will. We give him evaporated milk of the same nutri- tional value and he thrives. The digestive ferments are unchanged and THE ADAPTATION OF COW’S MILK 75 the food capacity remains the same; the change that takes place is in the most important of the milk constituents, the protein. The degree of heat used and the length of its application also have a controlling influence on the digestibility of milk. The most favorable effects are apparently produced through heating milk in the presence of starch and then adding an alkali or antacid. For example, an infant suffering from malnutrition is given a for- mula of— 10 ounces milk (top 15). 1 ounce milk-sugar. | ounce barley flour. 20 ounces water. 10 grains bicarbonate of soda. The food agrees to the extent that the child is comfortable, but he fails to make a substantial gain. He gains and loses an ounce or two weekly. We now order that the milk and the barley be cooked together in a double boiler for thirty minutes and that water be added at the completion to make up for that which passes off in evaporation. The food is given in the same amount at the same interval, and at once the child begins to take on weight. The feeding schemes have been identical excepting that in the latter we have added heat. Such an outcome will not take place in all cases, yet this effect has been demonstrated time and again. Repeatedly, when an infant has been brought for treatment of mal- nutrition and found to be taking a rational cow’s milk formula, the food strength has been continued as it was with the simple substitution of starch and malt soup for the original milk-sugar or dextrimaltose; the new carbohydrate portion being mixed together with the milk and cooked for thirty minutes in a double boiler. The same carbohydrate content has been maintained, the food has been given in the same amount and at the same interval. Following this, the record repeatedly has shown prompt and continuous gain in weight. Frozen Milk.—During the past thirty years many thousand quarts of frozen milk have been fed to infants under the senior author’s care. In no instance has it been demonstrated that frozen milk was the cause of illness. There is, therefore, little reason for the belief that milk which has been frozen disagrees with the average bottle-fed baby. Furthermore, little experimental evidence has been elaborated on this point indicating any very definite changes in the composition of milk in freezing. Nevertheless many pediatricians make it a rule to boil all milk that has been frozen, ascribing otherwise unexplained diarrheal attacks to neglect of this practice. The Use of Alkalies and Antacids.—The casein of human milk when it enters the infant’s stomach separates into small, flocculent masses. Cow’s milk entering the infant’s stomach, without an addition of an alkali or other modifying medium, is precipitated by the pepsin in the stomach and forms a heavy curd, consisting of paracasein, which fails of digestion or assimilation, and at which the child’s stomach often rebels. The adaptation of the casein of cow’s milk to the child’s digestive capac- ity, so as to maintain suitable nutrition, is a central point around which 76 THE PRACTICE OF PEDIATRICS the whole subject of infant feeding revolves. It will be noted in the formulas for cow’s milk feeding that lime-water is used as a diluent. This is used not simply to dilute the milk nor to render it alkaline, as has frequently been stated, but also to prevent the coagulation of the casein and the resulting formation of tough curds of paracasein. Simple dilution with water may make a smaller curd, but does not produce the fiocculent character peculiar to human milk that follows the addition of alkalies and antacids to cow’s milk. In the presence of an alkali the casein does not combine with the acid in the stomach; consequently the resulting acid coagulation does not take place. For this reason alkalies and ant- acids are added to cow’s milk. Usually the additions are too small. Poynton, of London, has advocated the use of citrate of soda with a view to preventing the solid coagulation of the casein. It is claimed that by using citrate of soda, 1 grain to the ounce, sodium paracasein is pro- duced, which is a fluid. Citric acid is liberated and unites with the cal- cium, forming the citrate of calcium, which is absorbed. Signs of indigestion of the casein in the milk are usually pain and discomfort. There are usually acute attacks of colic. There may be constipation, or diarrhea alternating with constipation, associated with the passage of many hard curds in the stools, the patient losing steadily in weight. In such instances the best means of adaptation consists in reducing the amount of protein to a total of 1 per cent, by dilution with water, and the addition of sufficient alkali, such as lime-water, bicar- bonate of soda, or citrate of soda, to form a curd more readily attacked by the digestive juices. One who feeds many infants will not be fully in accord with the belief, which is now fashionable, that the casein of cow’s milk is a factor of no importance in its adaptation. Whey Feeding.—Whey mixtures may be of temporary use. In whey the casein is largely removed—about 0.3 per cent, remaining. Analyses of whey show a nutritional equivalent of about: 0.5 per cent. fat. 0.9 per cent, lactalbumin. 0.3 per cent, casein. 4.5 per cent, sugar. As whey is ordinarily made, it is impossible to obtain a lower percentage of casein than 0.25. The amount of casein will oftentimes reach 0.5 per cent, unless it is heated and strained a second time. The deficiency in fat may be overcome by adding gravity cream (p. 66) of the same age as the milk from which the whey is obtained, in the proportion of 1 or 2 ounces to a pint of whey. This, of course, carries with it a very small amount of casein, which may make a total beyond the child’s digestive capacity. Low protein must be given only during acute illness or indigestion, and should be a diet for temporary purposes until the child is able to care for more suitable nourishment. Adaptation Through Peptonization.—When a child has incapacity for cow’s milk to such a degree that he is not able to take milk prop- erly diluted and given at suitable intervals, peptonization may often aid us, although we have frequently been sorely disappointed in its use. Theoretically, peptonization—the predigestion of the food—should be a THE ADAPTATION OF COAV’s MILK 77 solution of many digestive problems. Its efficiency in actual use may be learned from mortality statistics of children under two years of age in large cities, an immense proportion of the deaths being due either pri- marily or secondarily to nutritional errors. Not every infant, of course, is given peptonized milk; but if it possessed the value claimed for it by some of its advocates, the demand would be such as to compel its universal use, and difficult feeding cases would be no more. In using peptonized milk the protein strength should be reduced to 1 per cent.—the lowest point compatible with safety. The amount and intervals of feeding should correspond with those suggested for the age of the patient. The following method has served best: Fifteen minutes before nursing the bottle is removed from the ice and from one-eighth to one-fourth of a tube (Fairchild’s peptonizing tube), depending upon the amount of milk in the bottle, is added. The bottle is then placed in water sufficiently heated—110° to 120° F.—to make it the right temper- ature for a child at the end of ten minutes. The degree of the temperature of the water must of necessity vary according to the temperature in the bottle and the amount to be heated. So-called complete peptonization produces a product with a decidedly bitter taste, which few children will take. This form of milk in which there is a complete conversion of the casein has been most useful in two types of cases: For Garage.—During acute or chronic illness when a child cannot take food by the natural method, as in diphtheric paralysis, or when he will not swallow on account of an acute inflammatory disease of the throat, such as peritonsillitis, retropharyngeal abscess, or retropharyn- geal adenitis, or v:hen he is in a comatose condition from any cause except intestinal infection, the feeding of completely peptonized milk by gav- age (p. 853) is of inestimable value. For Nutrient Enema.—In conditions when stomach feeding is im- possible either by gavage or the natural method—conditions met with in persistent vomiting due to acute cerebral diseases, in recurrent vomit- ing, in acute gastric indigestion—and as an accessory means of feeding when sufficient nourishment cannot be taken by the stomach, the colon feeding of completely peptonized, skimmed milk has a decided field of usefulness. Feeding children by the bowel, however, is usually possible for a few days only, because of the local irritation produced by the nutri- ment and by the passage of the tube. Skimmed milk, peptonized, with the addition of the white of egg makes the best nutrient enema for such cases (p. 98). It should be given at a temperature between 90° and 95° F. at from six- to eight-hour intervals. The tube should be introduced at least 9 inches. In cases of recurrent vomiting, repeatedly both hunger and thirst have been relieved by feeding in this way. Adaptation by the Use of Cereal Gruels.—It is claimed by many excellent observers that the use of cereal gruels causes a mechanical division of the casein, and it is thus more readily acted upon by the di- gestive juices. While we use gruels largely as milk diluents, and fre- quently as milk substitutes, we have yet to be convinced that in difficult feeding cases they possess any great value in the adaptation of milk to the child’s digestive capacity, unless given in sufficient concentration 78 THE PRACTICE OF PEDIATRICS to change the consistency of the food. They are valuable adjuncts to the diet in cases in which weak milk foods must be given, but we do not recall an instance in which we thought the use of a stronger casein possible because of the cereal-water diluent. One who has fed gruels as diluents in a large number of cases for years will have had abundant opportunity to see enormous curds vomited and passed by the rectum by children on a milk and gruel diet in spite of test-tube demonstrations representing the process of curdling which takes place in the stomach and showing a minute division of the curd when the milk is treated with gruels. The advantage of a cereal diluent lies in the fact that a greater amount of food is thereby given, the starch often being tolerated better than sugar. Malt-soup Feeding.—The use of malt-soup extract offers a most satis- factory method of making cow’s milk assimilable. The chief use of this food is in malnutrition cases of slow-growing infants who, though not actually ill, fail to show a satisfactory growth. In treating bottle-fed infants who suffer from colic and marked constipa- tion due to casein incapacity this food has also considerable use. The milk strength considered suitable for the condition and age of the child may be used. Lime-water is not employed because of the presence of carbonate of potash in the malt soup. The maltose and flour, a con- siderable portion of the latter having been dextrinized, takfe the place of other carbohydrates in the mixture. The milk and flour mixture, strained and added to the solution of malt soup and water, should be placed over a slow fire and “simmered” for thirty minutes with constant stirring. Excess of malt soup may produce vomiting, so that any increase should be made with caution. Condensed and Evaporated Milk.—In not a few cases the feeding of fresh cow’s milk, manipulate it as we may, is impossible. For such cases another breast milk substitute is available, a cow’s milk product in which a portion of the water content has been removed by evaporation at a low temperature. Condensed milk is in the market in three forms—fresh condensed milk sold in bulk, condensed milk to which cane-sugar is added, sold in hermetically sealed cans, and evaporated milk without the addition of sugar, sold in hermetically sealed cans. The best known and most readily available brands are Borden’s condensed milk, known as the Eagle Brand, and Borden’s evaporated milk, known as Unsweetened Evaporated Milk. The Eagle Brand contains cane-sugar in considerable amount, and is rarely to be used. The unsweetened brand is evaporated milk without the addition of sugar. In the condensing process the milk is heated to 200° F. It is then transferred to vacuum pans, where it is main- tained at a temperature of 125° F. until sufficient water is evaporated to bring the product to the required condensation. The analysis of the Eagle Brand is as follows: Fat 9.5 per cent. Sugar 54.67 “ Total protein 7.84 “ Ash 1.68 “ Water 27.31 “ THE ADAPTATION OF COW’S MILK 79 The analyses of unsweetened evaporated milk and the unsweetened condensed milk sold in bulk are very similar. The standard maintained is as follows: Fat 8.3 per cent. Sugar 10.05 “ Protein 7.1 “ Ash 1.43 “ Water 73.07 “ The above products are respectively typical of numerous other con- densed and evaporated milks on the market, the percentage figures show- ing the composition of the different products being remarkably similar. Sweetened condensed milk (e. g. Eagle Brand) by reason of its high sugar content is to be fed in dilutions of about 1 to 8, or a dram to the ounce of water. In the nutrition of young infants wTith a good sugar toler- ance the value of this brand of condensed milk is probably greatest. In using milk of this type for feeding that known on the market as evaporated milk is to be preferred. A fresh can must be opened daily. The fact that the evaporated milk is free from added sugar makes possible the feeding of a larger amount. One part of the milk to 3, 5, 6, or more parts of diluent may be used. Thus, the formula for a day’s food would read like the following: 7 ounces evaporated milk. 28 ounces water. carbohydrate {S-ao„p extract. 10 grains bicarbonate of soda. Milk of this strength affords a nutritional value of 1.66 per cent, fat, 1.43 per cent, protein, 2.01 per cent, sugar. To this mixture carbo- hydrate in the form of starch, cane-sugar, dextrimaltose, milk-sugar, or malt-soup extract may be added to raise the total carbohydrate to 6 or 7 per cent. If malt soup and starch are used, cooking will be re- quired. (See Malt-soup Feeding, p. 78.) More or less of the evaporated milk may be used as may be required. Many infants of very weak di- gestion will thrive on the evaporated milk thus given when all other artificial methods fail. To the very young, and those with poor digestive capacity, and to athreptics, a lesser amount of milk may be given at first—1 part of milk to 7 or 8 of diluent—the quantity being increased as the infant shows improved capacity. As the child grows older and increases in weight the amount of evap- orated milk may be increased. We have never given a stronger formula than 14 ounces of the unsweetened evaporated milk, 26 ounces water, carbohydrate to 6 or 7 per cent. The weight chart (Fig. 7) shows the progress made by a child on this scheme of feeding. Notes on the chart indicate when the evaporated milk feeding was begun and the various strengths used. Previously the child had been given various fresh cow’s milk formulae. In not a few cases the food seems to be better assimilated if the entire mixture—milk, starch, and sugar—is kept just under the boiling- point in a double boiler for thirty minutes. Occasional stirring is neces- 80 THE PRACTICE OF PEDIATRICS Fig. 7.—Chart showing progress made on evaporated milk. Food value indicated in percentages and calories. sary, and at the completion of the heating process water should be added to bring the food to the original amount. When the child has remained comfortable for six to eight weeks or THE ADAPTATION OF COW’S MILK 81 longer on such feeding, almost always with a gain in weight, one feeding daily of a plain milk mixture may replace a feeding of condensed milk. A raw milk mixture should always be given in weaker strength than the child’s age calls for. In spite of the dilution it may occasion indiges- tion, colic, and the passage of curds. In such an event the evaporated milk and its diluent must again be the sole diet for two or three weeks; then the use of ordinary milk may again be attempted. After a few days or a week, in case one such feeding is taken without inconvenience, a second feeding may replace another evaporated milk feeding. In this way the number of plain milk feedings may be gradually increased until the child is taking a rational diet of this milk alone. Illustrative Case.—A six-month-old baby took daily three feedings of condensed milk and three of raw milk. Attempts were made to give him the fourth feeding of raw milk, but invariably with disastrous results. He was slightly under weight, but in a fair general condition. We have successfully managed a great many of these difficult feeding infants, as described above, withholding ordinary milk feeding until the child is taking the evaporated milk well and gaining, then gradually advancing the raw milk feeding until, when the child is five or six months old, he is taking daily and assimilating two or three feedings of the fresh milk. When six months old, and sometimes earlier, he may be given suitable raw milk feedings exclusively. By the above method the desired end of complete plain milk feeding is reached sooner than when small quantities of cow’s milk are added to the evaporated milk mixture. In beginning, it is best to give the raw milk at the first or second feeding in the morning, when the digestive powers are stronger than they are later in the day. When the second raw milk feeding is given, it should never immediately follow the first. The raw milk and the evap- orated milk should be alternated until more than one-half of the daily feedings are of fresh milk. If this method has to be used for a considerable period it is best to give 2 or 3 teaspoonfuls of orange juice daily. A convenient time to use the orange juice is one hour before the second feeding.

The foregoing formula) may require changing to suit the individual case. If the formula seems to produce indigestion, an ounce of the milk may be removed and an ounce of the water substituted. If the formula agrees, but the child is not satisfied, the formula may be increased by adding an ounce of milk and removing an ounce of water. In arranging formulae for the different ages, it is assumed that the child is of average weight and vitality. Very small, delicate children may at first require reduction in the milk strength and a lesser amount at each feeding. THE ADAPTATION OF COW’S MILK 83 Dry Milk Preparations.—Preparations of dry milk powder from which the moisture has almost completely been removed have during the past few years come into general use. In the sense that these preparations are as yet in the hands of a few concerns and are dissimilar in composition depending on their source, they are to be regarded as proprietary foods. The principles of their use are identical, however, and their application to infant feeding may be taken up at this point. Dry milk is prepared by two chief methods. By one the milk is sprayed into a heated chamber in the form of a fine spray which is at once con- densed to a powder falling to the floor of the chamber like fine snow. By the other process the milk is instantaneously dried by flowing over hot revolving cylinders. In most of the preparations the fat content is kept low to insure better keeping of the product. The advantages of dry milk are its ready transportability, its stability, its cleanliness, its con- venience to the consumer in the ready preparation of food. Dry milk probably has its greatest value in the feeding of small in- fants whose capacity for finely divided casein is good, but whose fat and sugar tolerance is low. The protein element in this type of food may often be raised above the proportion customary in feeding without symp- toms of indigestion resulting, and the gains in weight thus attained are often spectacular, particularly when an infant getting an inadequate breast-milk supply is given supplementary dry milk feeding. In not a few instances, however, after a fortnight or more of favorable progress such an infant will begin to show signs of protein intolerance, the first of which is often a strongly ammoniacal urine productive of excoriation of buttocks. If food is longer continued, even with admixture of alkali, gastric indigestion and diarrhea may be induced. In such instances sub- stitution of weak evaporated milk feeding for a time is often beneficial. Dry milk filled a particular field of usefulness during the war as a food for infants in countries where fresh milk was unobtainable. The various preparations of malted milk contain in most instances maltose and dextrin in addition to dry milk. The tabulation given (p. 93) includes a number of these complex foods. In the main they are applicable to cases in which the sugar tolerance is not diminished' and have no advantage over dry milk to which appropriate carbohydrate is added. Cereal Gruels; Starch Feeding.—Much discussion has taken place during the past few years concerning the use of cereals in infant feeding. The cereals consist of plant embryos surrounded by a mass of highly nutritious proteins and carbohydrates in the form of starch, which nour- ishes the embryonic plant until it becomes rooted in the ground. As the developing plant needs nourishment it converts the starch into dex- trin and maltose. Cereals are analogous to eggs in that the germ is packed away in a supply of exceedingly nutritious food, which in the process of development it converts into tissue. Almost all of the pre- pared infant foods are made from cereal flours with or without the ad- dition of a little dried milk or sugar, or from cereals in which the starch has been transformed into dextrin and maltose. The proprietary meal foods, which consist of baked flours of different kinds, are useful aids in infant feeding and most useful as milk substitutes when milk must temporarily be withheld. The conversion of starch into dextrin by the 84 THE PRACTICE OF PEDIATRICS baking process is so slight that it may be ignored. Robinson’s barley flour, Cereo Co.’s barley flour and the other gruel flours, and Imperial Granum (baked wheat flour) require boiling before use. They may be prepared according to the instructions given in the formulary (p. 95). It is customary in bottle feeding to begin with a cereal by at least the fifth to the seventh month, by using a cereal water as a diluent of the milk mixture. For this purpose barley or granum is usually employed. Very often in out-patient work we begin with a cereal diluent very early in life in order to make the food mixture more nutritious. This method of feeding is useful when accurate modifications are not possible and when the child for any reason cannot take a milk formula as strong as age and nutritional requirements demand. Such cases are frequently seen in the marasmic, the malnutrition, and the difficult feeding class. The addition of 2 or 3 tablespoonfuls of flour to the daily food will increase its nutritive value not a little. That boiled starch may be digested by the youngest and most marasmic infant has been proved. The principal use of these flours, however, is in the treatment of gastro-enteric diseases, where cereal may with safety replace the milk for considerable periods of time. By eliminating milk from the diet and giving carbohydrates, a putrefactive culture-field is removed and a less favorable soil is furnished for the development of the pathogenic types of intestinal bacteria; further, there are no by-products formed to produce intestinal toxemia or kidney irritation. Two even table- spoonfuls of these flours to 1 pint of water give approximately a food strength of 0.07 per cent, fat, 0.3 per cent, protein, 2 per cent, carbohy- drate. In order to increase the nutritive value, sugar may be added in sufficient quantity to bring the carbohydrate percentage up to 5. The addition of the sugar also makes the cereal more palatable, and there- fore more acceptable to the patient. During an invasion of scarlet fever, pneumonia, or any of the ill- nesses of childhood which may be accompanied by great prostration, the usual foods, whatever their nature, should be withheld, and the cereal gruel, alone or mixed with chicken or mutton broth, used as a very satis- factory substitute. Likewise later in the disease it is never well to give full milk while fever and prostration are present. Cereal gruels are especially serviceable as diluents of the milk in conditions where this combination must often furnish the nutrition for a period of days. The use of the baked-flour gruels, with sugar or without, as a means of nutrition should be continued only during the active symptoms of the disease, whether it is scarlet fever or one of the intestinal diseases. In no sense are these gruels advocated as exclusive foods for infants or for growing children. This error has been made with most disastrous results. The Infant's Capacity for Starch Digestion Proved by Experiment.— It has been claimed with more or less tenacity by different writers that the young infant possesses no capacity for starch digestion. That the youngest infants may digest starch is now definitely established. The experiments of Moro, Zwiefel, Corwin, Hess1 and Kerley2 have proved the earlier beliefs erroneous. 1 Amer. Jour. Dis. Child., October, 1912. 2 Kerley, Mason, and Craig, Arch. Ped., July, 1906, THE ADAPTATION OF COw’s MILK 85 Concentrated Cereal-milk Mixtures.— History.—In 1911 Hahn1 re- ported good results from the administration of 5 to 6 per cent, grits in milk in such form that 1 liter represented 1000 calories. McClure2 re- ported the case of a neurotic vomiting infant who promptly ceased vom- iting when fed thick barley gruel for which thick farina and milk was later substituted. Sauer3 applied the method, which he elaborated in- dividually, to 12 cases of pyloric obstruction with striking success in 11 cases, and a year later Porter4 reported similar success with 10 pyloric cases. Mixsell5 applied thick cereal feeding successfully to cases of mal- nutrition dependent on vomiting, and Current and Durand6 extended its use to breast-fed babies with colic. Thick cereal feeding is therefore no longer to be regarded as a radical experiment, but rests upon an established basis. Representative case histories together with a more detailed review of the literature are avail- able in a report by Graves.7 One of the patients in his series who had a complete breast milk in- tolerance took a cereal mixture readily from a spoon beginning at one week of age. The Method.—The feeding of concentrated cereal in milk is based on the simple physical behavior in the stomach of a paste as opposed to a liquid. The liquid in vomiting cases, particularly those dependent on pylorospasm is rejected with a spurt or gush while the cereal paste mass containing more food in smaller bulk distends the stomach less, apparently has some soothing effect on the irritable gastric mucosa, and eventually induces pyloric relaxation which permits of the passage of gastric contents provided no true organic closure of the pylorus exists. “The cereal of choice is probably farina, because of its property of great expansion under cooking, thus permitting thickening of the mixture with a minimum amount of added starch. Three or 4 table- spoonfuls in a 20-ounce formula will ensure sufficient solidification by the time cooking has reduced the quantity one-third, although greater concentration may at times be advisable. Obviously the amount of water to be used is not arbitrary. Skimmed milk, evaporated milk, dry milk powder, or breast milk may be incorporated in preference to whole milk. Sugar of any form may be employed, but should be main- tained at a low percentage until tolerance is proved, with due regard for the possible ill effect of maltose when vomiting is a chief symptom. For an infant under six months of age an allowance of 2 or 3 tablespoon- fuls at a feeding ordinarily suffices. If more is demanded the indication is for a thicker rather than a larger feeding. “The calorie guide is more valuable than the percentage method in calculating the ration. Empirically it has been found that 60 to 75 calories per pound of body weight may be required to maintain a satis- factory gain, and that a larger allowance may be demanded and tolerated. 1 Med.

Sci., April, 1922, clxiii, 576. 86 THE PRACTICE OF PEDIATRICS “The importance of starch-free stools is likely to be magnified. Com- plete starch digestion is, of course, advantageous, but if incomplete digestion of the starch gives rise to no concomitant colic, distention, or hiccup the method may be continued with appreciation that the cereal is at least serving as a good vehicle. “Water between feedings is desirable, but not at all times necessary.”1 For further discussion of the application of this method to the treat- ment of vomiting the reader is referred to p. 218. Butter-flour Feeding.—The butter-flour feeding of Czerny and Klein- schmidt2 is prepared by gently heating 4 level tablespoonfuls of ordinary salt butter in a pan until foaming occurs, and the odor of volatile fatty acids has disappeared (three to five minutes). To this is added 5 level tablespoonfuls of fine wheat flour. Again the mixture is heated with constant stirring until the mass is thin and brown (three to five minutes). Then 20 ounces of water in which 3 level tablespoonfuls of sugar have been dissolved is added. The mixture is then boiled and rubbed through a fine sieve. The percentage constitution of this stock solution is fat 5.75 per cent., carbohydrate 10 per cent., protein 0.5 per cent., provid- ing 26.6 calories per ounce.3 To this stock solution cow’s milk is added in quantities dependent on the weight and requirements of the child. The following directions constitute a guide: For a child under 6| pounds, use 2 parts stock solution and 1 part milk; for example: Stock solution (prepared as above), 12 ounces Fat, 4.6 per cent. Cow’s milk, 6 ounces Carbohydrates, 8.2 per cent. Seven feedings in twenty-four hours Protein, 1.5 per cent. 2§ ounces at each feeding 24.6 calories per ounce For an infant over 6| pounds, use 3 parts stock solution and 2 parts milk. For example an 8-pound child failing to gain should receive: Stock solution (prepared as above), 15 ounces Fat, 4.6 per cent. Cow’s milk, 10 ounces Carbohydrates, 7.8 per cent. Seven feedings in twenty-four hours Protein, 1.7 per cent. ounces at each feeding 24.3 calories per ounce For larger children the proportion of milk is increased as, for example, for a child of 11 pounds: Stock solution (prepared as above), 17 ounces Fat, 4.9 per cent. Cow’s milk, 17 ounces Carbohydrates, 7.0 per cent. Seven feedings in twenty-four hours Protein, 2 per cent. 4 to 5 ounces at each feeding 24.4 calories per ounce Because of the high caloric value per ounce, it is usually best not to feed more than 3 to 4 ounces per pound of body weight in twenty-four hours, water being given separately. High caloric feedings, 75 to 90 calories per pound, are well borne. The stools produced by this type of feeding are bright, glistening and yellow with a pungent aromatic odor, similar to that of breast-milk stools. 1 The Role of Concentrated Cereal-milk Mixtures in Early Infancy, Amer. Jour. Med. Sci., April, 1922, clxiii, 576. 2 Czerny and Kleinschmidt: Jahrb. fur Ivinderhcilk., 1918, lxxxvii, 1. 3 Griffith and Mitchell, New York Medical Journal, August 3, 1921. THE ADAPTATION OF COW’S MILK 87 Butter-flour feedings are especially indicated for children who have good stools, and do not vomit, but fail to gain properly on other rational feedings. Czerny and Kleinschmidt consider it most important that the relation of butter to flour by weight be 1 : 1. Buttermilk and Lactic Acid Milk.—As ordinarily prepared buttermilk is a skimmed milk preparation of a composition approximately as follows: Fat 0.5 to 2 per cent. Lactose 3 to 4 “ Protein 3 to 4 “ Lactic acid 0.5 to 0.75 “ This composition varies, depending on whether the buttermilk is pre- pared from skimmed milk, whole milk, or cream. The advantages of such food are its low fat percentage, its compar- atively low sugar percentage, and its relatively high protein content which comprises more than the usual proportion of soluble albumin together with casein in a finely divided form which cannot be acted upon by rennin. As ordinarily prepared buttermilk is soured naturally and contains not only the lactic acid organisms largely responsible for the souring, but various other bacteria certain of which may be pathogenic. It is more rational to use prepared lactic acid milk than ordinary buttermilk, not only because of the bacterial factor involved but also because the composition of prepared lactic acid milk may be controlled more readily. Preparation.—Lactic acid milk is ordinarily prepared artificially by adding 1 or 2 of the commercial lactic acid tablets, such as the Lactone tablet of Parke, Davis & Co., to fresh milk at room temperature and allowing it to stand over night, the principle being the same as that em- ployed in the East in making ordinary Bulgarian sour milk with a “starter” portion obtained from the milk of a previous day. Sterilization of the milk before the artificial souring is not necessary if the milk is known to be fresh and clean. Such sterilization delays the action of the lactic acid organisms. A simple scientific method of preparing lactic acid milk that readily commends itself was worked out by Sherman and Lohnes.1 Taking ad- vantage of the known facts that the fine clotting desired in the milk occurred at an acidity point of 60 as measured by decinormal sodium hydroxid, and that when the acidity reached 170 to 190 fermentation spontaneously ceased, these authors simply allowed the milk selected to ferment for twenty-four hours in a warm place in the usual manner and then diluted the product with boiled milk in equal amount, thus cutting down the acidity to below 95. This acidity still being above 60 insured the clotting of the added milk after which the mixture was kept on ice. These and other investigators have employed corn syrup extensively because of its cheapness and the character of its sugar to supplement the lactic acid milk in the feeding of infants whose sugar tolerance permit- ted. Surprisingly large amounts of sugar in a lactic acid medium have 1 Jour. Amer. Med. Assoc., October 2, 1920. 88 THE PRACTICE OF PEDIATRICS been taken even by very young and underweight infants with resulting improvement in stools that had previously been putrefactive, and rapid gains in body weight. Undoubtedly the good effects of lactic acid milk are in part due not only to the lactic acid itself, but to the contained organisms which tend to discourage the growth of a putrefactive intestinal flora. Surprisingly good results, however, are obtained by the simple addition of lactic acid to whole milk in the proportion of 1 dram to 1 pint.1 Protein Milk.—This preparation is designated also as albumin milk, Eiweissmilch, and Finkelstein’s milk. Its use was developed by Finkel- stein and Meyer and has long been a matter of routine in hundreds of institutions. Variations in the process of making this food are respon- sible for much of the disagreement which still exists respecting its value. For this reason we have selected Lowenburg’s description of Finkelstein’s method of preparation2 as a reliable guide: “A teaspoonful of any milk coagulant, as rennin or pepsin, is added to 1 liter of whole milk. This is thoroughly mixed and the vessel containing the material is placed in a water-bath the temperature of which is about 110° F. This raises the milk to about 100° F. Within a short period coagulation occurs and the entire mixture becomes solid. The mass is then incised by a complete crucial incision. This facilitates the escape of the whey. The coagulum is now placed in a suspension bag (made of either four or five layers of cheese- cloth or of a porous material resembling thin, unbleached muslin) for a period of four hours. This permits all the whey to escape, carrying with it the major portion of the salts and the sugar of milk. The tough curd is then pushed through a hair-mesh sieve in order to completely com- minute it. This process is accomplished with a wooden spoon, or drug- gist’s pestle, or with a wooden instrument resembling a potato masher. It is repeated four or five times, adding about £ liter of water to facili- tate the passage through the fine sieve; £ liter of good buttermilk is added to the finely divided coagulum, and the entire mixture is again passed through the sieve. The bulk of the product should equal 1 liter, and, should it not, the deficiency is supplied by adding sufficient water. The mixture is now brought to the boiling-point, meanwhile stirring thoroughly and constantly from the moment that heat is applied. This maneuver is crucial in its effect upon the perfection of the finished product. If it is not employed, the finely divided curd will become one solid mass. This accident seems to occur with great frequency in America, while in Finkel- stein’s kitchen it rarely ever happens.” The product thus obtained contains: fat 2.5 per cent., protein 3 per cent., lactose 1.5 per cent. Protein milk is thus poor in fat and sugar and rich in protein, which exists in a finely divided state as calcium paracasein. Uses.—The chief value of such a milk lies in its applicability to the treatment of diarrheal conditions, notably those prevalent in the hot summer season. The low sugar content, tending to diminish intestinal fermentation, the relatively high fat content contributing to the forma- 1 Marriott and Davidson, Jour. Amer. Med. Assoc., Dec. 15, 1923, vol. 81, pp. 2007- 2009. 2 Lowenburg, Infant Feeding and Allied Topics, 1916, 126. THE ADAPTATION OF COW’S MILK 89 tion of soap stools and the high protein in a subdivided easily digestible form all combine to make this albumin milk acceptable to infants suffer- ing from summer diarrhea or difficulty in the digestion of protein and fat together with abnormal susceptibility to the irritant effects of sugar. The lactic acid content of protein milk is also beneficial and probably, in those cases in which the end-product is not boiled after the addition of the buttermilk, lactic acid organisms themselves have some antiputre- factive effect. Dilution of the food may be made to fit individual cases, and when it is poorly taken saccharin may be added, 1 grain to the quart, to improve the taste. Within four or five days after beginning this feeding, or as soon as the stools have appreciably improved, carbohydrate in the form of starch or sugar should be added to increase the nutritional value. Ultimately the transition from protein milk to boiled milk and cereal water, or to an evaporated milk formula with low sugar content may be accomplished. Not before this time may the infant be expected to show much gain in weight. Typical mistakes in protein milk feeding cited by Strauch1 are as follows: “1. Insufficient dosages of protein milk in the beginning of treatment. “2. Too late addition or too small amounts of carbohydrate. “3. Withdrawal of carbohydrate or excessive diminution of food dur- ing a recurrence of the symptoms of nutritional disturbance after a period of improvement.” Dry Protein Milk.—To meet the demand for a protein milk which could be easily made in any household without special knowledge a number of preparations of albumin milk in powder form have been marketed. These preparations require only to be added in correct amounts to warm water before feeding in order to duplicate with fair accuracy the com- position of ordinary protein milk. The analyses of several of the more common substitutes of this class are given on page 93. In general, our experience would incline us to give preference to the original form of liquid protein milk whenever this is obtainable. Protein Milk Made From the Evaporated Product.—The standard protein milk of Finkelstein and Meyer as suggested in the preceding article fails us in not a few cases, and for three reasons: (1) The patient refuses to take it because of the decidedly sour taste. (2) When taken it is not well retained in not a few instances. (3) The curd may pass through the intestinal tract unchanged. This is particularly apt to be the case in the very young. In order to overcome the difficulties it was necessary that a method be devised that would obviate the disadvantages of the standard product, would supply something that the most delicate infant would take and retain, and that would give the results obtained with the standard product in cases in which it was impossible. At the senior author’s suggestion the Walker-Gordon Laboratory made a series of experiments in preparing a protein milk, using the evaporated milk for this purpose. It seemed that 1 International Clinics, vol. iv, Series 32, 90 THE PRACTICE OF PEDIATRICS if so many marantic infants could be fed on the evaporated milk by the prescription, a practice with which we have had marked success for several years, that the addition of the .Bulgarian bacillus might make this milk useful in treating those of the same type who had diarrhea. It was found that the eight-hour period of incubation ordinarily employed was unnecessary for satisfactory results, likewise that the addition of protein in the form of powdered curd was not essential. It was dem- onstrated also that an incubation period of two hours gave a much more palatable mixture, one that was taken very readily, was rarely vomited and relieved the diarrhea, at the same time producing a gain in weight. In the preparation of the milk a culture is used which is prepared as follows: One quart of skimmed milk is boiled for one hour, it is then cooled to 90° F., and divided into two equal parts. One-half tube of Bacillus acidi lactici is added to one portion, and one-half tube of B. bulgaricus to the other portion. The cultures are incubated eight hours at a temperature of 80° F., then shaken well, cooled, and kept on ice. The protein milk is prepared as follows: One teaspoonful of each culture added to 1 pint of the evaporated milk formula employed is incubated two hours. After this time the milk should be packed in ice to prevent a further incubation. It will be appreciated that this procedure is quite impossible in the home. It may be used, however, in any hospital in which there is an ordinarily well equipped diet kitchen. In using this method the evaporated milk formulae (p. 81) may be employed. It is best to use a weak mixture not giving over 1) per cent, of fat or over 3 per cent, of lactose until the diarrhea has subsided. The carbohydrate content may be increased by the use of barley flour in amount that brings the total carbohydrate percentage up to 5 or 6. As the diar- rhea improves the fat and sugar content may be increased. Every summer we feed a considerable number of cases along these lines, continuing the incubation process until well on into autumn. Illustrative Case.—A case demonstrating the type in which we employ this feeding was a marantic infant five weeks old weighing 6 pounds, 15 ounces. For two weeks he had been having from 5 to 7 loose green mucous stools daily. The following was pre- scribed: fat 1.25 per cent., protein 1.25 per cent., starch 5 per cent., lactose 4 per cent. In three days the child was reported constipated and hungry. The food was then in- creased to fat 1.50 per cent., protein 1.50 per cent., starch 2 per cent., lactose 7 per cent. In five days more he had entirely recovered, was hungry, and weighed 7 pounds, ten ounces, having made a gain of 11 ounces in the eight days. Every year, particularly in the autumn, we have a large number of infants suffering from chronic indigestion in which diarrhea or a tendency to diarrhea is a prominent symptom. These infants who are usually brought to us on a barley and skimmed milk diet of varying strengths, have always been difficult feeders and have incompletely recovered from some acute intestinal disorder. With these patients the establishment of thriving has been most difficult and it is in such cases that the method presented gives brilliant results. Infants who will thrive on fresh cow’s milk during the cooler months in New York City and its environment may not be able to digest the same milk during the hot months. In such THE PROPRIETARY FOODS 91 cases the evaporated protein milk has aided us greatly as a temporary substitute for a fresh cow’s milk formula. It is not claimed that the scheme presented is a method of infant feeding; it is a means of temporary feeding for sickly, delicate infants who are having a hard time. By this means we can give a well-balanced ration of increased caloric value which the patient is able to utilize, with resulting cessation of the diarrhea and gain in weight. THE PROPRIETARY FOODS The foods on the market prepared for purposes of infant feeding are very numerous. From our knowledge of the composition of mother’s milk we learn what nutritional elements are required, and approximately in what relative proportions these elements must exist, in order to supply the child with the food which nature intended him to have. The ex- amination of the milk of thousands of nursing women shows that it con- tains from 2.5 to 4 per cent, fat, 6 to 7 per cent, sugar, and 1 to 1.5 per cent, protein; and this furnishes the balanced ration with normal caloric requirements. These figures may be put down as the normal limits of human milk, and they are so simply because the infant will thrive and grow best when the nutritional elements in approximately the above proportions are supplied to him. It is within these limits with few excep- tions that the food must be kept in order that there may be normal growth and development. While the child may exist and temporarily do fairly well on a percentage of fat lower than 2.5, he will invariably show defective growth if the protein remains persistently under 1 per cent. The chief disadvantage in the infant foods which are used without the addition of cow’s milk lies in the fact that they do not contain the nutritional elements as they exist in normal breast milk, and besides, of necessity, they are all cooked foods. A further objection to the use of proprietary foods in general is their excessive cost. This is readily contributed to by advertisements which direct the feeding of babies both well and sick. It is not well to put too much reliance on the analysis sometimes published by the proprietary food manufacturer. This type of food is decidedly weak in animal fat for the reason that there is no means of keeping more than a small per- centage of it in a food without its becoming rancid. When considerable percentages are indicated in the analysis it is certain that the fat does not consist of butter fat. The quantity of animal milk protein is like- wise deficient, and what is present has been cooked, which detracts ma- terially from the value of the food in infant nutrition. Scurvy is not an infrequent result of the exclusive use of these foods. The Uses of Proprietary Dried-milk Foods.—It is to be remembered in spite of what has just been written that this type of food is condemned because of its being an unsuitable food when used exclusively and per- sistently. Hysteric, general condemnation is unjust. Throughout this book the uses of the proprietary foods will be mentioned from time to time and dwelt upon. Milk is often an important factor in the production of constipation; and the importance of this food in the nutrition of “run- about” and older children who are on a general diet is secondary. In 92 THE PRACTICE OF PEDIATRICS such cases cow’s milk may be replaced by one of the proprietary dried- milk, malted foods which has a laxative effect. During acute illness and in convalescence and in certain forms of malnutrition such foods are usually readily digested and may help us over difficult places. Proprietary Foods to Which Fresh Cow’s Milk is Added.—These are not foods in the usual acceptation of the term, and if they are used alone, independent of milk, the patient will soon present a sorry spec- tacle. They are largely sugars, composed of maltose and dextrose, which are derived from starch. Some contain a considerable quantity of un- converted starch. When added to the water and milk mixtures they furnish the soluble carbohydrates and free starch, and thus fulfil this function of the food with results as good as, but usually no better than, those obtained with milk-sugar and a cereal gruel. Maltose is a laxative sugar. In some cases of constipation in the bottle fed it may replace the milk-sugar in equal quantity, with decided advantage. In other cases this change to maltose is without effect. According to our observation, the statement that the addition of maltose to cow’s milk facilitates its digestion is unfounded. We have tried this method in many cases, but have never been able in conse- quence to use a stronger cow’s milk mixture. The true test of such a measure is in treating the delicate and in feeding difficult cases, rather than well babies who thrive regardless of the carbohydrate employed. The maltose preparations, then, in the sense that they may contain a small amount of protein and a laxative sugar, are useful and to be recommended when such a carbohydrate is needed. The Proprietary Beef Foods.—Numerous preparations of this nature are on the market, and there has been abundant opportunity to test their value. Without going into a lengthy discussion as to how and under what conditions these preparations have been used, it is sufficient to say that as means of nutrition for children they play a very unimportant part. Their principal use is in illness, in which they act as a stimulant, and to a less degree as a food. They all make weak protein mixtures when diluted so that the child can take them. The possibility of supply- ing any great amount of nutrition by their use is negligible; occasionally, however, they may be used to advantage. When milk is withdrawn, they may be added to the cereal gruel substitute. If there is diarrhea, great care must be exercised, as the proprietary beef preparations as well as beef juice may aggravate this condition. On account of the creatinin which they contain these foods should not be given in any of the forms of nephritis. Another obstacle which limits their use is that a child soon tires of them. They can rarely be given more than two or three times in twenty-four hours. Valentine’s is the preparation usually selected. It may be given in solution—\ to | teaspoonful to 6 ounces of the diluent. The Composition of Infant Foods.—In the table on p. 93 an attempt is made to group some of the more common proprietary foods according to their leading characteristics and to give fairly dependable figures showing the respective analyses. The list of such foods is being constantly augmented and there is no guarantee that change in the manufacture of any one of the patent foods may not at any time alter the proportions of its ingredients. For practical purposes in spite of the fact that the THE PROPRIETARY FOODS 93 Percentages. Group. Name of food. Fat. Carbohydrate. Protein. Cane- sugar. Lactose. Maltose. Dextrins. Starch.

SPECIAL SUPPLEMENTARY FOODS AND THEIR PREPARATION Numerous adjuvants to milk are of value in infant feeding, particularly as a means of fulfiling the demands of the borderline period between infancy and childhood. For short intervals certain of these foods may be used as substitutes for milk when the latter for any reason is unavailable or is poorly tolerated. Formulae Beef Juice.—Take a round steak, cut into pieces the size of a horse chestnut, place in a buttered pan in a hot oven, and bake for fifteen minutes; remove from the pan and press out the blood; add salt to the taste. Beef, Mutton, and Chicken Broth.—Take 1 pound of meat free from fat, cook for three hours in 1 quart of water, adding water from time to time, so that when the cooking is completed there will be 1 quart of broth. When the broth is cool, remove the fat, strain, and add salt to the taste. Scraped Beef.—Broil round steak slightly over a brisk fire. Split the steak and scrape out the pulp, using a dull knife. Egg-water.—The white of 1 egg, thoroughly beaten in 1 pint of cold boiled water; strain; add salt to the taste. Coddled Egg.—Take a fresh egg, place it in a pan of boiling water, put on the back of the stove and stand for three minutes, having pan tightly covered. Cornstarch Pudding— Dissolve 1 tablespoonful of cornstarch in a little milk. Heat 1 pint of milk to nearly boiling-point. Add cornstarch slowly, then 1 tablespoonful of sugar and stir until it thickens. When cool add 5 drops of flavoring. Soft Custard.—Heat 1 cup of milk to boiling-point. Add 1 yolk of egg well beaten, one teaspoonful of sugar, and a pinch of salt. Cook in a double boiler, stirring until it thickens. Strain and add 5 drops of flavor- ing. Oatmeal Jelly.—Oatmeal, 4 ounces; water, 1 pint; boil for three hours in a double boiler, water being added, so that when the cooking is com- pleted a thin paste will be formed. This while hot is forced through a colander to remove the coarser particles. When cold a semisolid mass will be formed. Wheat Jelly and Barley Jelly.—Wheat jelly and barley jelly are made in the same way as oatmeal jelly, using cracked wheat or barley grains. Barley-water No. 1.—Robinson’s barley flour or Cereo Co.’s barley flour, 1 rounded tablespoonful; water, 1 pint. Boil thirty minutes; strain; add water to make 1 pint. In making barley-water No. 2, 2 tablespoonfuls of the flour are used, and for No. 3, 3 tablespoonfuls are used. Rice-water No. 1.—Rice, 1 tablespoonful; water, 1 pint; boil three 1 Morse and Talbot, Diseases of Nutrition and Infant Feeding, 1915, 230, 231; Holt and Howland, Diseases of Infancy and Childhood; Mellins Food Co., Proprietary Foods, Formulae. SPECIAL SUPPLEMENTARY FOODS AND THEIR PREPARATION 95 hours, adding water from time to time, so that there is 1 pint of rice- water at the end of the three hours. In making rice-water No. 2, 2 tablespoonfuls of rice are used. Oatmeal-water No. 1.—Oatmeal, 1 tablespoonful; water, 1 pint; cook three hours and add water to make 1 pint. In making oatmeal-ivater No. 2, 2 tablespoonfuls of oatmeal are used. Percentage Gruel Flours.—There is on the market in tin boxes, the covers of which are used as measures, a series of flours, especially made for pre- paring cereal gruels and jellies of known percentage composition. On the labels are given only the cooking directions for preparing plain or dextrinized gruels, and their composition when different quantities of flour are used.

Dextrinized Barley-water.—Robinson’s barley flour or Cereo barley flour, 3 tablespoonfuls; water, 1 pint; boil thirty minutes; add water to make a pint. When lukewarm (100° F.), add 1 teaspoonful of Cereo; strain; this changes the starch into dextrinized maltose. Oatmeal-water No. 1.—-Oatmeal, 1 tablespoonful; water, 1 pint; cook three hours and add water to make 1 pint. 1 In making oatmeal-water No. 2, 2 tablespoonfuls of oatmeal are used. Imperial Granum-water No. 1.—Imperial Granum, 1 tablespoonful; water, 1 pint; cook thirty minutes and add hot water to make 1 pint. In making Granum-water No. 2, 2 tablespoonfuls of Granum are used. Whey.—Put 1 pint of fresh milk into a saucepan and heat it lukewarm, not over 100° F.; then add 2 teaspoonfuls of Fairchild’s essence of pepsin and stir just enough to mix. Let it stand until firmly jellied, then beat with a fork until it is finely divided; strain, and the whey, the liquid part, is ready for use. Junket.—To 1 pint of fresh milk add 2 teaspoonfuls of sugar and 1 junket tablet or 2 teaspoonfuls of essence of pepsin. Allow it to stand over a fire until the temperature is 100° F.; then add vanilla as a flavoring and allow it to stand until the curd is set, when it should be placed on ice. Prune Juice.—Take 1 pound of prunes, wash thoroughly, place in a pan, cover with cold water, and allow to stand over night. Place on stove next morning, bring to a boil, and allow to simmer until very soft. Strain 96 THE PRACTICE OF PEDIATRICS off the juice (which should be 8 ounces) and give the required amount for the infant. For older children the pulp may be used with the juice after putting through a sieve. Lactic Acid Milk.—The preparation of lactic acid milk is described on page 87. MILK FOR TRAVELING In making long journeys with infants by land or water the feeding of the child is an important matter, and advice is often sought by mothers who wish to make the contemplated trip with the least possible risk. It is, of course, desirable that no change be made in the milk commonly used, and there are means of treating the milk and of keeping it which enable us to assure the patient of reasonable safety. It is convenient with New York City children to have the milk prepared at the Walker-Gordon Laboratory, where at a trifling expense small ice-boxes can be obtained which contain sufficient space for a few days’ supply of milk and which can be conveniently carried on cars and boats. Larger boxes with a capacity of 12 quarts may be used for an ocean voyage. The smaller box will need refilling with ice, which is usually readily secured once or twice a day. The larger box for ocean voyages is packed in ice and placed in a cold-storage room of the vessel and will not need repacking during the trip. The milk prepared for a journey should be cooled to 45° F. as soon as it is drawn and kept at this temperature until it can be sterilized at a temperature of 212° F. for twenty minutes. It should then be cooled rapidly to at least 50° F. and kept at this point until used. These directions can be carried out by any intelligent family. When this is done, the milk will be safe for use for the time required—from seven to eight days. Of course, laboratory milk is available for comparatively few. But the sug- gestion as to the making of an ice-box can be followed in any town or village, so that a milk laboratory is not essential. All that is required is the ice-box, the quart fruit-jars or quart milk-bottles, and clean milk. Those who for any reason cannot avail themselves of the milk thus pre- served will find in canned evaporated or condensed milk or in dry milk a fairly good substitute. Malted milk or any of the dried milks on the market may be used as a temporary substitute for cow’s milk. SUBSTITUTES FOR STOMACH FEEDING In the management of the diseases of children conditions arise from time to time which necessitate the nourishment of the patient by chan- nels other than the stomach. In persistent vomiting, when there is an acute congestion of the stomach, as in an acute gastro-enteric infection, in cyclic vomiting, and in vomiting due to some more remote cause, as meningitis or nephritis, the patient must receive water and food in order to sustain the system until the exciting factor is removed. Nutrition by means other than stomach feeding may be necessary in retropharyngeal adenitis or abscess, in stricture of the esophagus, in diphtheria, in the exanthemata, and in pneumonia during the course of active delirium, A substitute for stomach feeding is also often useful SUBSTITUTES FOR STOMACH FEEDING 97 in marasmus, for the generally delicate, and in nourishing those with reduced assimilative powers. Various means of substitute feeding have been attempted from time to time. Nutritive suppositories have been advocated and proved failures, perhaps because of our inability to place them sufficiently high in the bowel. Placed in the rectum, they excite peristalsis and are expelled. Rectal and Colonic Feeding.—Any means of treatment which is disagreeable both to patients and attendants, and difficult of execution, is very liable to fall into disfavor unless pronounced beneficial results are the rule. While absolutely nothing can be promised so far as supplying nutrition by this means is concerned, careful observation and experience tell us that in a certain number of cases the measure is of much value. When the treatment will be of service in nourishing the patient can be determined by trial only. In children, particularly in very young chil- dren, on account of the ease with which peristalsis is excited, nutrition by this means is less frequently successful than in the adult. Never- theless, the method has been of material assistance in many a trjdng situation. Not a few of the failures are due to a lack of appreciation of the details of the procedure. Directions to mothers or nurses to inject a certain quantity of some particular food, unless specific instructions are given, will usually be carried out as follows: A hard glass or rubber tip will be passed into the rectum from 1 to 2 inches. Through this the fluid will be forced. In a very few minutes, perhaps immediately, the bowel will empty itself into the napkin or bed-pan, the enema being of no ser- vice. This is what may be expected and what will happen when the child is given the nutrient enema in this way. The hard tip, placed within the anal ring, and the fluid are very apt to excite vigorous perstalsis. In order that the nourishment may be retained, it should be carried high up into the descending colon. The advantages of this method are that the fluid is much better retained, and, on account of the greater sur- face of mucous membrane with which it comes in contact, it will be quickly and more completely absorbed. How to Give a Nutrient Enema.—The nutrient enema is best given as follows: A soft-rubber catheter, No. 18 American, or a small adult size rectal tube is slipped over the small tip of an ordinary fountain-syringe. The tube should not be too flexible nor yet too stiff, and the catheter is to be preferred. If too flexible, the instrument folds readily on itself when the point meets with any resistance, and the fluid escapes perhaps 1 or 2 inches within the anal opening. If the tube is too rigid or if force is employed, the mucous membrane and the parts may very easily be lacerated. The position of the child while the enema is being given is important. He should rest on his left side, preferably in Sims’ position, with the buttocks elevated to a plane at least 4 inches higher than the shoulders. A pillow or a folded blanket covered with a rubber sheet should always be available for this purpose if a bed-pan is not at hand. The child, if old enough to understand, should be assured that no harm will come to him. With the patient in position and an assistant to hold him, the anus is 98 THE PRACTICE OF PEDIATRICS covered with vaselin. It is not enough to oil the tube. The tube at- tached to a fountain-sj'ringe is warmed and well oiled and passed into the rectum. The lower end of the bag should be 3 feet higher than the child’s body. There may be some straining at first, but with the child in a proper position one may pass a tube of the right degree of flexibility high into the intestine in a few seconds. The tube should be introduced about 9 inches—far enough at least to be felt in the descending colon; then the fluid is allowed to pass rapidly into the bowel. When the bag is emptied, the tube is rapidly withdrawn and the child, although allowed to change to the dorsal position, is encouraged to rest on his side. In any event the buttocks must be kept elevated for at least one-half hour. In using small amounts of fluid it is well to allow for the quantity which may remain in the tube of the syringe and in the catheter after the enema is given. In managing older children, who exert much bearing down or straining, it may be necessary to attach the catheter to a Davidson sjWnge or to an ordinary rubber or glass piston-syringe of large size, in order to provide sufficient force to overcome the pressure exerted by the ab- dominal muscles. The nutriment should be neither too hot nor too cold. With either of these extremes, peristalsis is apt to be excited. A temperature of 95° F. is the most satisfactory. If bowel action has been fairly free, previous washing with a normal salt solution is not necessary. If there has been no movement for six hours, it will be well first to use an irri- gation of normal salt solution. Glycerin should not be used. The irrigation should precede the enema by from fifteen minutes to half an hour. Nourishment Not to Be Used in the Rectum.—Oils or fats in any form, even though pancreatinized, should not be used. Alcohol should be used only in very urgent cases, and then it should be well diluted and used not oftener than once or twice in twenty-four hours, because it has a decidedly irritant action on the intestinal mucous membrane and is not well retained. When used alcohol should be diluted with from 12 to 16 parts of water or an equal quantity of skimmed milk, which has been peptonized or pancreatinized. In giving stimulants by the rectum, whisky is usually employed in quantities from \ ounce for a child two years of age, to 1 ounce for a child from six to ten years of age. Nourishment to he Used.—By far the best food for rectal alimen- tation is skimmed milk completely pancreatinized. It is better retained and more completely assimilated than any other form of nutriment which we possess. In cases in which it is desired that a considerable amount of fluid be absorbed by the intestine, the pancreatinized milk may be diluted with normal salt solution. Where such milk is not avail- able, the whites of 3 raw eggs, mixed with a normal salt solution, may be given. Not infrequently the whites of 1 or 2 raw eggs are given in the pancreatinized skimmed milk, this combination constituting the best form of nutrient enema. The predigested proprietary preparations, the so-called “peptones,” have not proved satisfactory in our hands. The amount of nourishment to be used at one time varies with the age and condition of the child. COMMON DIGESTIVE DISORDERS OF INFANCY 99 Ordinary Amount to Be Given in Enema Under three months 2-4 ounces Prom three to six months 4-6 “ From six to twenty-four months 6-8 “ After the twenty-fourth month 8-16 “ Because the first enema is not retained, it does not follow that a sec- ond given immediately thereafter will share the same fate. In not a few instances, when the second enema has been given ten minutes after all or the greater part of the first had been expelled, the entire second amount has been retained. It is rarely wise to repeat the enema oftener than at six-hour intervals, and when the intestine shows a tendency to intol- erance the intervals should be increased to eight or ten hours. This means of nutrition in children is of temporary use at best. The period of its application in the average case, even when tolerated at first, is only two or three days. In a few instances it has been found practicable to use the method longer. Illustrative Cases.—During the summer season a very delicate three-month-old child, weighing 6 pounds and 10 ounces, retained 2 ounces of completely pancreatinized skimmed milk, given at six-hour intervals for three days, and 3 ounces at eight-hour intervals for eight days longer, making a period of eleven days in which the enemata were employed. Such tolerance of the large intestine, however, is very rare. In another case the use of enemata following an operation for intestinal obstruction with protracted vomiting and prostration unquestionably saved a child’s life. In a third severe case of cyclic vomiting, which was seen in considtation, the vom- iting had persisted for three days. This child was six years of age. He showed marked emaciation, and suffered from intense thirst; his pulse was weak and soft. A nutrient enema was given, composed of 8 ounces of pancreatinized skimmed milk, 8 ounces of normal salt solution, and the whites of two eggs. Not one drop was expelled. In one- half hour the boy claimed to feel better. The intense thirst was relieved and he fell into a res.tful sleep. In six hours the enema was repeated, about 4 ounces being expelled. This was followed by enemata at eight-hour intervals, 8 ounces of the milk with the whites of two eggs being given, all of which was retained. At this point the vomiting abruptly ceased and further enemata were not required. Common Digestive Disorders of Infancy The Recognition of Digestive Disturbance.—In order successfully to carry on the feeding of an infant one must be alert to slight departures from the normal which singly are often overlooked and many times are of no significance, but collectively make up the picture of “disturbed balance” which may be followed by persistent indigestion. Successful infant nurses and the mothers of large families acquire a sort of sixth sense, the possession of which enables one to judge whether an infant is doing well or poorly even before a change in the appearance or behavior of the baby can be detected by the less experienced. The value of such a developed instinct is unquestionable. It may be acquired by any one who will make the study of minor manifestations on the part of the infant a serious undertaking. Hunger.—In the case of a strong, lusty nursling an error in diagnosing hunger can hardly be made. The insistent cry, the crowding of the baby’s hands into his mouth, the beginning of sucking even before the nipple can be grasped, the recurrence of the cry when nursing is inter- rupted, the normal sleep following the filling of the stomach all make un- mistakable the recognition of the infant’s simple periodic need for food. In the bottle-fed infant who has a poor digestive capacity or has been 100 THE PRACTICE OF PEDIATRICS improperly fed the hunger symptoms may pass unrecognized. Hunger in such an infant is often associated with colic or may follow directly after vomiting, or recur without apparent reason after a feeding in caloric value far above the normal requirements. To understand such a case, to correctly gage the relative importance of hunger and more serious disturbance, in guiding the feeding, and to withhold increase in food in the presence of a consistent gain by a baby who “is always hungry,” calls for a differentiation between normal and abnormal hunger, possible only when all the factors are considered by one who is experienced. In general, hunger in the absence of vomiting or symptoms indicative of intestinal indigestion may be taken as a favorable symptom and not infrequently will justify a temporary increase in food, disproportionate to computed caloric needs. In the event of rapid gain following such increase in the food, the hunger manifestations will probably diminish in intensity so that the food may be maintained without further increase till the augmented weight of the infant entitles him to more. Hiccup due to spasm of the diaphragm is ordinarily a minor symp- tom due to the distention of the stomach with air swallowed at a too rapid nursing, or to the presence of gas from carbohydrate or butyric acid fermentation. This symptom may be relieved by the administra- tion of a little very warm water and by holding the infant upright and patting his back. Persistent hiccup may yield to warm abdominal ap- plications and an enema. The baby with recurrent hiccup should have slower feedings, food in smaller volume, and possibly food with lower carbohydrate and fat content. If he does not vomit or show by his stools evidence of indiges- tion, the hiccup may be interpreted simply as a mild warning that diges- tive capacity is being moderately taxed. Colic.—This is a more serious condition due to the presence of gas in the intestine. The peristalsis thus excited takes the form of definite cramps upon the occurrence of which the subject draws up the legs and screams. The diagnosis of colic is facilitated by noting the presence of tympanites and the occasional passage of gas from the bowel at which times the baby may manifest relief. A saline enema affords more lasting relief. A discussion of this condition in greater detail will be found in the section on Intestinal Diseases, pp. 225-227. Vomiting.—The significance of this symptom depends upon its char- acter and cause. Vomiting with eructation of gas is often due to neglect of the practice of patting the infant on the back while he is held upright after feeding. Air swallowing from too rapid feeding increases this susceptibility. Simple regurgitation or “spilling over” is regarded as a physiologic form of relief to an overfilled stomach. The indication to meet this con- dition is obvious. In infants of a neuropathic type (of which class there are not a few) this habit may become complicated by actual rumination. Sour vomiting at intervals indicates fermentation from too much fat or sugar in the feeding. High fat feeding tends to induce retention of gastric contents beyond the period when emptying is normally accom- plished. Vomiting of very acid contents in such cases frequently follows the taking of a fresh feeding. COMMON DIGESTIVE DISORDERS OF INFANCY 101 Other common forms of vomiting (p. 199) with the important excep- tions of those types dependent on spasm and obstruction in the gastro- intestinal tract belong less exclusively to infancy. Pylorospasm and pyloric stenosis occasion forcible projectile vomiting of a type requiring special consideration. (See p. 207.) Intussusception and congenital obstruction of the intestine present surgical signs and symptoms. Vomiting dependent on reflex causes (particularly teething), vomiting with pertussis, meningitis, peritonitis, and the onset of acute infective diseases with fever, and finally, the vomiting belonging to acidosis, all occur in infancy and require treatment considered under discussion of the respective underlying conditions, to be presented later. To many cases the treatment outlined in the section on Acute Gastric Indigestion (p. 200) is applicable. Certain particular phases of the subject of vomiting in infancy may be considered at once. The vomiting infant should be watched by the phys- ician for a considerable time to determine the nature of the vomiting, because statements by the family cannot always be relied upon. The vomiting may be projectile. This, if habitual, is very apt to mean the existence of pylorospasm or hypertrophic pyloric stenosis (p. 207). In vomiting due to unsuitable food productive of gastric irritation the ejected material usually comes up in large mouthfuls during the interval between feedings, and is of a disagreeable sour odor. Regurgitation of small amounts of partially digested food may occur in this type of case. In all such cases, however, rumination (p. 206) is to be thought of, a condition which, although fairly common, is usually overlooked by the attending phys- ician. It is very sure to be overlooked if the child is not watched for a half-hour or so after the feeding. Spasmophilic infants vomit much more readily than those not so constituted, but we have never been impressed by the so-called “nervous vomiter” or “habit vomiter.” Careful observation of such cases will usually disclose a hyperstalsis or pylorospasm. The point of hyperstalsis is frequently overlooked. The pyloric opening at best is small, and the overacting stomach in its efforts to force food through the pylorus is very apt to take on a reverse stalsis, with resulting rejection of the food. Every year we see several cases in which the vomiting is apparently due indirectly to mucous gastritis. In these infants there is a production of thick gelatinous mucus which covers the lining of the stomach and unquestionably plugs the pyloric orifice and acts in a mechanical fashion to prevent the passage of the food, the results being identical with those of pylorospasm. In the cases that are occasioned by unsuitable food and resulting gastric irritability the treatment is obvious and will be found under Acute Gastric Indigestion (p. 200). For all vomiting infants, regardless of the nature or cause of the vomiting, the use of a daily stomach wash- ing is always of advantage, and in some instances gives most surpris- ingly favorable results. The cases of mucous gastritis particularly are quickly relieved by daily stomach washing. Because of this tendency to varying degrees of mucous gastritis in all deranged stomachs, whether the causative factor is mechanical or otherwise, lavage is indicated. A 102 THE PRACTICE OF PEDIATRICS 5 per cent, solution of bicarbonate of soda is the fluid used. From 2 to 4 ounces should pass into the stomach and be siphoned out, this procedure being repeated until the water is clear. Constipation.—This is perhaps the most common functional digestive disorder of infancy. Its consideration in detail is taken up on p. 267. When present in a feeding case that presents no other departures from the normal, constipation rarely constitutes a serious problem. It is note- worthy that constipated babies (perhaps because the slow expulsion of the intestinal contents gives more time for complete food absorption) characteristically gain weight rapidly. Obstipation, in distinction from constipation, serves as a valuable symptom in the differentiation of pyloric stenosis from simple pyloro- spasm. Diarrhea.—Frequent watery stools are common in breast-fed infants during the first days of life and have little significance. As the breast milk improves the diarrheal tendency usually subsides. In other instances the frequent stools may persist and the condition may perhaps be traced to errors in the mother’s diet or laxatives which she is taking and ex- creting in part through the medium of her breast milk. Diarrhea in the bottle fed, as a rule, demands lowering of the sugar content in the infant’s food, and frequently the adoption of gruel to replace the sugar removed. Intestinal indigestion and the various inflammations of the intestinal tract in which diarrhea is the prominent symptom are discussed in a later section (pp. 230-253). The Ammoniacal Diaper.—Probably every physician has been told by the mother or nurse that the baby’s diaper smells of ammonia. South- worth found in a study of several cases that the condition was readily corrected by eliminating or reducing the fat in the milk or by giving alkalies, such as magnesia or citrate of potash. This author, quoting Czerny and Keller, accounted for the excessive ammonia excretion as “depending upon the chemical property of am- monia to combine with acids as an alkaline base. While under normal conditions all but a little of the ammonia becomes urea and is excreted as such, if under abnormal conditions there is present in the body an excess of unoxidized acids for whose neutralization the available supply of fixed alkalies does not suffice, the ammonia can then take the place of fixed alkalies and form with the acids ammonia salts, which will be excreted in the urine.” Zahorsky1 found that the disorder was largely limited to artifically fed infants and that high fat milk feeding and the giving of orange juice and of egg were among the etiologic factors in caus- ing the ammonical diaper. The ammonia was found to be liberated from ammonia containing compounds in the urine under the action of an alkali present in the diaper—soap, lye, lime, or stool. Cooke2 demonstrated the presence of a urea-fermenting, ammonia- producing organism, “Bacillus ammoniagenes,” in the stools of artificially fed infants with ammoniacal diapers. The ammonia production was found to be inhibited by acid intestinal contents, being reduced when the intake of fat was low, and in the case of the. breast-fed infant. When the 1 Amer. Jour. Dis. Child., vol. x, 1915, pp. 436-444. 2 Ibid., November, 1921, pp. 481-492. COMMON DIGESTIVE DISORDERS OF INFANCY 103 diaper was impregnated with antiseptic the ammonia formation was readily controlled. Treatment.—The management of these cases as suggested above consists in reducing the fat to the child’s capacity, or in the use of alkalies. In most cases the reduction of the fat content in the food has been all that was required. Persistent ammonical urine not infrequently follows prolonged feeding of dry milk owing to defective utilization of the high protein content in this food. If the ordinary measures are not effective in relieving the condition in such a case, the substitution of another form of food is indi- cated. The practice recommended by Cooke of wringing out the dry, clean diapers in boric acid solution, 1 : 20, and again drying them before ap- plying is a dependable routine preventive measure applicable to all cases. Evidence Afforded by the Stools.—Breast Milk Stools.—Infants on the breast average two to three large stools daily, although the number may range from one to five and still be consistent with perfect health. Their color is usually of a bright yellow or orange tint, and their character of a smooth and homogeneous consistency, with a slightly acid reaction. The odor is not as offensive as that of the cow’s milk stool, as there is less putrefaction of the breast milk protein while in the intestinal tract. The bulk or residue corresponds to the amount of ingested food. Cow’s Milk Stools.—Infants on the bottle usually average only one stool a day, which often is smaller than that of the breast-fed baby. The color is lighter and the proportion of feces to the amount of food taken numerically less when the infant is artificially fed. Hard Constipated Stools.—A hard constipated stool, when not pro- duced by any mechanical cause, is usually due to a deficiency in the food of either carbohydrates or fats, generally the latter. Food too low in total solids, leaving an insufficient residue, is also a cause. Irregular habits in the time of going to stool and a lack of systematic general train- ing also play a part. Sterilization and, to a lesser degree, pasteurization, make milk somewhat constipating. Loose Watery Stools.—This type of stool is seen in indigestion, with fermentative changes in the carbohydrates, and to a lesser extent in the fats. The stools vary in color from a yellow or yellowish brown to green. They are usually alkaline in reaction and have a foul, musty odor. Curds are seldom seen and there is very little mucus. Stools in Hard Balls.—This variety of stool is usually due to an excess of fat in the food. The feces vary in color from a light yellow to a light gray. They are sometimes large and hard, and at other times dry, small, and crumbly. “Scrambled Egg” Stools.—Stools of this order are seen when the car- bohydrate digestion is at fault. Bacterial fermentation of the starch or sugar which is not assimilated by the organism gives rise to loose, green, frothy movements. These are very acid, frequently causing ex- coriations of the buttocks and surrounding parts. Mucus in Stools.—Mucus excretion denotes a form of irritation in the digestive tract which gives rise to an excessive secretion from the mucous glands of the intestine. It is almost invariably present in ab- 104 THE PKACTICE OF PEDIAT1HCS normal stools. Mucus intimately mixed with feces indicates the source of the trouble to be in the small intestine; if on the outside of a con- stipated stool, in the rectum; or if in combination with a clay-colored stool, in the duodenum. Blood in Stools.—In older children blood intimately mixed with the stools would suggest an ulceration of the stomach or small intestine. When on the outside of a constipated stool the blood may indicate a rectal lesion, an anal fissure, diverticuli, or incomplete intussusception. A stool composed of a jelly-like mass of blood and mucus without fecal material is very characteristic of intussusception. Malsena neonatorum or hemor- rhage of the newborn is characterized by a profuse discharge of blood from the rectum. Curds in Stools.—'Curds are one of the most frequent of the abnormal constituents. Two kinds are found: one firm and tough and very hard to press out, insoluble in ether, varying in size from a small pea to a hick- ory nut, with a brown or greenish coating, but white on cross-section, known as a protein curd; the other is composed of fat, easily pressed out, does not sink in water, varies in color from white or yellow to green, is somewhat soluble in ether, and is not hardened by formalin. Stool Examination.—Much may be learned from the gross appearance of the feces. Variations in color ranging from the clay color character- istic of the presence of fat and absence of bile, to the dark green or black stool produced by the ingestion of spinach, bismuth, or iron are all readily appreciable by the naked eye. The consistency of the stool, its size, and many other points regarding it are also readily apparent, and much ad- ditional information relating to the presence of such contents as strings of mucus and foreign substances may be obtained by pressing a portion of the stool between glass plates. For the determination of the finer degrees of digestive capacity, and the bacterial content of the feces, microscopic and chemical analysis is essential. A few of the more common tests are the following: Fat droplets not ordinarily present in the stool to any marked extent are stained black by osmic acid, and orange with 3 per cent, sudan III in 50 per cent, alcohol. Fatty acid crystals, the presence of which is abnormal, are detected on cooling a slide upon which has been heated a drop of feces and 2 drops of 30 to 50 per cent, acetic acid. Starch grains are stained dark blue or black by Gram’s iodin solution. The proportion of Gram-positive to Gram-negative bacteria in the stool is less important than the type of organism predominant. In the stool of protein putrefaction Bacillus aerogenes capsulatus and B. putrificus or their spores are significant. In that of .carbohydrate fermentation B. acidoph- ilus and Gram-positive diplococci predominate over the organisms of the colon group and B. aerogenes capsulatus. Pathogenic organisms of common occurrence are those of dysentery, including Amoeba coli, B. typhosus, the tubercle bacillus, and streptococci productive of mem- branous colitis. The presence of occult blood is best determined by the benzidin test. Carbohydrate fermentation and protein putrefaction may be studied MARASMUS (ATHREPSIA; INFANTILE ATROPHY) 105 by simple fermentation tests combined with color and reaction observa- tions. For the actual details of microchemical examination of the feces the reader should consult a standard work on clinical pathology. Disorders of Nutrition in Infancy MARASMUS (ATHREPSIA; INFANTILE ATROPHY) Under the title of marasmus will be considered those cases which are associated with and dependent upon derangement of function of the gastro-enteric tract. Tuberculosis, syphilis, and atelectasis are consequently excluded, these affections being considered elsewhere under their respective headings. Age.—Marasmus is seen most frequently in young infants under nine months of age. Cases are frequently seen, however, from the ninth to the twelfth month, and comparatively few between the twelfth and eighteenth months. Etiology.—A great deal of research work has been done among maras- mic infants in order to determine the nature of the condition, but as yet no satisfactory explanation has been offered. The disease is un- questionably due to defective intestinal assimilation. The principal fact that disproves the existence of any atrophic condition or neces- sarily severe derangement of function is that these patients very often make complete recoveries, becoming perfectly normal children after three months or more of treatment. The Usual History.—The history of these cases is as follows: The mother could not or did not nurse the baby. The child was put on cow’s milk, which was usually given too strong or in too large quantities— often both errors were combined, or the milk may have been too old when used, and improperly cared for; in any case the milk disagreed, the child was made ill, there was loss in weight, cow’s milk was discontinued, and one of the infant foods, alone or combined with milk, was given. The child’s digestion was thoroughly disordered, and the foods failed to agree. There was vomiting or regurgitation, with undigested, green stools, or both combined, while the loss in weight continued. The child may have been inherently weak or may have shown a cow’s milk idiosyn- crasy to help account for the lack of success in the milk feeding. Usually there followed a series of experiments with different kinds of food and methods of feeding, the vomiting, diarrhea, or colic continued with wast- ing, and when the child reached the hospital or office he was perhaps six months of age and weighed from 6 to 9 pounds, presenting a typical athreptic picture. Some of these children are born with a digestion that is apparently incompatible with cow’s milk mixtures. Others have their digestive capacity for cow’s milk hopelessly deranged by improper feeding methods. The majority of the cases occur among the overcrowded tene- ment poor—the worst possible environment for a delicate infant. There is little or no protein assimilation, so that any approximation to normal growth is impossible. Marasmic infants may also possess a poor fat ca- pacity, and if there is, in addition, a diminished sugar capacity the pro- teins of the tissues are drawn upon to supply heat and energy, with re- 106 THE PRACTICE OF PEDIATRICS suiting progressive emaciation. Heredity, environment, and the season of the year all influence the prognosis. Infection as a Contributing Factor in Marasmus.—In our manage- ment of athreptics we have been so occupied with nutrition and the gastro-intestinal fault that other possible etiologic agencies may have been neglected. Occult infections may and do play a very decided part in some of these cases. Thus during a service at the Babies’ Hospital, out of 17 cases in which blood-cultures were made, 5 were positive, and of these 5 infants, 4 died. Of the remaining 12 patients with negative cultures, 8 died, and of the 4 that recovered, 1 had an otitis; and 1 a fu- runculosis of mild degree, while the remaining 2 had no demonstrable lesions. Of the 8 fatal cases, there were only 2 in which there was no evident infection. The infection varied from an otitis to a severe bron- chopneumonia. The blood-cultures in each case were taken when the infant was losing in weight and apparently retrogressing without any digestive disturb- ances. In two instances the clinical evidence (if it might be called such) consisted simply of a subnormal temperature, well-digested stools, and progressive loss in weight. In two others there existed a temperature and later signs of a bronchopneumonia, while a third showed Klebs- Loffler bacilli in the nose. Blood-counts were of no aid in diagnosis. Marasmic infants who fail to thrive on suitable food and good gen- eral management, whether there are evident digestive disturbances or not, should be thoroughly examined for hidden infections. In not a few of those who show progressive loss in weight there has been a sup- purative otitis without active symptoms. In others there has been a bacteremia, the only symptom being that of progressive loss in weight. It is not infrequent to find miliary tuberculosis at autopsy where it was not suspected during life owing to absence of any fever. Pyloric Obstruction as a Cause of Marasmus.—All malnutrition infants with persistent vomiting should be examined and observed to deter- mine whether or not there is trouble at the pyloric outlet. Utheim1 has made a careful study of a number of cases of athrepsia and demonstrated a greatly increased loss of food material as seen in the stools during the active stages. The loss may be as great as 26 per cent, of the food intake, but utilization of the food is much greater as im- provement takes place in the infant’s condition. Pathology.—There is no lesion or set of lesions peculiar to infantile atrophy. The senior author has personally autopsied a large number of cases. There is often a strip of hypostatic pneumonia, perhaps a large area of atelectasis. Now and then the liver is fatty or shows fatty areas. The spleen, kidneys, and heart are pale. The stomach and intestines contain thick, sticky mucus, which when removed shows a pale, washed- out-appearing mucous membrane. Blood infections with the pyogenic cocci have explained the etiology in several recent cases. Treatment.— The Wet-nurse.—An important factor determining the prognosis is the possibility of obtaining breast milk. That a great majority of cases of simple athrepsia recover, and often recover promptly1, making a most satisfactory growth when a wet-nurse 1 Amer. Jour. Dis. Child., vol. xxii, pp. 329-350. MARASMUS (aTHREPSIA; INFANTILE ATROPHY) 107 is secured, is proof, as above stated, that the condition, so far as relates to any peculiar systemic state or pathologic condition, depends more upon the nature of the nutrition than upon the patient. In securing a wet-nurse the physician’s duties are by no means completed. The patient may not take kindly to the breast, and will have to be taught breast nursing. A great deal of time may be required in teaching older infants, those who have been on the bottle for seven or eight months. To this end various devices may have to be used. For the first nursing it is well to allow the child to go for an hour or two beyond the feeding time in order that his appetite may be voracious. It is advisable also to give the first few nursings in a darkened room with the person who has been accustomed to feeding the patient very near. Sufficient milk should be forced from the breast to enable the child to taste it. A little powdered sugar sprinkled on the nipple is a good means of increasing his interest. In some instances it has been necessary to cover the wet-nurse with a blanket or sheet, leaving only the breasts exposed; or it may be necessary to use the nipple- shield for a few days in order gradually to accustom the child to the change. We have yet to see a case in which success did not follow per- sistent effort. Often the nurse’s milk will not agree at first; but this is not surprising and need cause no discouragement. Breast milk ordinarily is a much stronger food than the child has been accustomed to, and it may produce vomiting, colic, or diarrhea. When indigestion follows, the nurse’s milk should be modified by giving the baby weak barley- water or plain boiled water, before the nursing in case he nurses well, or after the nursing in case he nurses poorly. One or two ounces of breast milk at a feeding is all that these patients can be expected to take dur- ing the first few days. The amount obtained may readily be determined by weighing the patient, without the trouble of undressing him, before the nursing, and then weighing him at intervals of from three to five minutes after the nursing has commenced. One ounce of breast milk is practically 1 ounce avoirdupois. These children, if not too weak, will take greedily almost anything from the bottle. The addition of 1 or 2 ounces of barley-water or plain water dilutes the milk and renders it easier of digestion, and furnishes at the same time the necessary fluid for the child. The most unpromising cases of marasmus are not to be despaired of nor the treatment relaxed, although the physician should be cautious in his prognosis. If the child is too weak or indifferent to swallow, the wet-nurse’s milk may be expressed, diluted, and given by gavage. In many cases evaporated milk (p. 78) may be used successfully for maran- tic infants. It is much easier of digestion than fresh cow’s milk, and is a temporary measure of much value. Illustrative Case.—The most pronounced and the most hopeless recovery case coming under our personal observation was seen in consultation in one of the suburbs of New York. The child was four months old and weighed 5 pounds. He was emaciated to a skeleton, having weighed 8 pounds at birth. The temperature for several days ranged between 92° and 94° F. A trained nurse and an unusually intelligent mother were in charge. Because of doubt respecting the accuracy of the thermometer reading, dif- ferent thermometers were used. The temperature was taken by the rectum. The attending physician had also taken it repeatedly, so that finally there was no doubt. The child was too weak to nurse. The breasts were accordingly pumped, and for each feeding he was given l ounce of breast-milk with an ounce of barley-water, to 108 THE PRACTICE OF PEDIATRICS which a few drops of sherry wine were added. This was given by gavage at two-hour intervals. He was wrapped in flannel and wool and surrounded with hot-water bottles. The food was retained and digested. In four days he could nurse, and was allowed to take a small amount from the breast and finish the meal with barley-water. The tem- perature gradually rose to the normal. More breast milk was allowed as he proved able to care for it, and the child made a perfect recovery, weighing 18 pounds when he was nine months old. This case demonstrated that a marasmic child is never a hopeless case until he ceases to live. Unfortunately, very few marantic children can have the benefit of a wet-nurse, but without a wet-nurse many of these cases are not hopeless. The use of evaporated milk (p. 78) and malt soup (p. 78) will furnish a satisfying diet in not a few instances. Marasmus is, of course, a very serious condition, but the chances are much better in a reasonably good home than in a hospital, where the story is often as follows: The patients take the modified milk or whatever is given them without inconvenience. The stools may be offensive if cow’s milk is given, or there may be consti- pation, or the stools may appear perfectly normal. As a rule, there is no serious diarrhea or any other evidence of an acute inflammatory process in the intestine. However, in spite of fairly normal stools, the patient grows thinner and thinner. After a time all food is refused, gavage is used as a last resort, and the child finally dies. The autopsy shows noth- ing but pale organs, with perhaps a strip of hypostatic pneumonia. Now and then one of these cases in a children’s institution or in a hospital recovers without a wet-nurse, but it is the exception proving the rule. Put these athreptics on a wet-nurse, as one should do at every oppor- tunity, and many of them will thrive in spite of the well-known unfavor- able influence exerted by institutional life upon the very young. In addition to putting the athreptic baby on the wet-nurse, his stomach should be washed once daily and he should live out-of-doors. In the cases of extreme dehydration transfusion, hvpodermoclysis or intra- peritoneal infusion (p. 850) may be employed. Outdoor Life.—Next to the wet-nurse we know of no agent fraught with so much good as is outdoor life. The season of the year exerts con- siderable influence on the prognosis. The athreptic bears the heat and humidity very badly, and the early summer mortality of all large cities is materially increased by these children, who wilt and die in institutions and tenements with the first two or three days of continuous hot weather. Parents residing in a large city who can so afford should send such chil- dren to the country not later than June 1st, to return, in this latitude (New York City), not earlier than October 1st. During the day the child should be on a porch or in the shade continuously. At night the windows of his sleeping-room should be wide open. During the cooler months, if the child is too ill to be taken out-of-doors, he should have from morning until evening a continuous indoor airing (p. 838). The sleeping-room should always communicate with the open air. The roof-garden in large cities is a most valuable aid in the management of athreptic children. Cases in Which a Wet-nurse is Impossible.—One phase of this most interesting and important subject has not been touched upon. We refer to the athreptic infant of the tenement, and those others in pri- vate lile for whom a wet-nurse is impossible. They furnish by far the largest number of our marasmic patients. Perhaps the most frequent MARASMUS (ATHREPSIA; INFANTILE ATROPHY) 109 error in the management of these cases is an endeavor to select at the start a food for the child to thrive upon. In doing this, almost invariably a stronger food is selected than the child is capable of digesting, and he is made worse by the attempt. Our ultimate object in treating these infants will be more readily attained if, at first, we attempt only to supply a food upon which they can exist without loss in weight. The number of calories necessary for an athreptic child is not great. It must be re- membered, furthermore, that we are not dealing with a case of infant feeding as the term is commonly understood. True, we are feeding an infant, but a sick infant, and the methods of feeding used for the com- paratively well do not apply here in all respects. The problem of nourish- ing these children is to be considered from two standpoints—that of the food and that of the baby, with special reference to the organs of digestion. The stomach, in many of these infants, is dilated, with a consequent lack of motility. Residual undigested food remains long after feeding. There has been a constant fermentative change, with the production of lactic and butyric acids, resulting in local changes of an inflamma- tory nature in the mucous membrane of the stomach, so that not only must the organ be prepared for the food, but the food must be adapted to the stomach capacity, and when this is done—when both require- ments receive due consideration—we are much more likely to succeed. Stomach Washing.—In all of these cases for the first few days of treat- ment it is advisable to wash out the stomach with sterile water, regardless of the presence of vomiting and regurgitation and regardless as to whether the child is bottle fed or breast fed. It is often surprising to note the amount of thick mucus and undigested food that will be washed from a stomach from which there has never been vomiting. The daily wash- ings enable the child to take more and stronger food. It may even be necessary to continue the washings for days. They may first be dis- continued when the water siphons clear and without mucus. They should be repeated if there are indications, such as regurgitation of sour water or mucus or loss of appetite. In one case in which there was chronic gastritis with athrepsia washings were continued at gradually lengthened intervals for six months. Temporary Feeding.—If the case is one with pronounced stomach in- volvement, a 3 per cent, milk-sugar solution should be given for twenty- four hours in quantity suitable for the age and size of the patient. The following day barley-water No. 1 (see Formulae, p. 94) is to be given, to which sugar is added to make the mixture 5 per cent. Cow’s Milk.—While it is doubtful if the child can take cow’s milk, after this period of stomach rest and stomach washing it may be at- tempted. Two drams of as safe milk as can be obtained are added to every second feeding of the barley-ancl-sugar-water. If it agrees, after a day or two, 2 drams are added to every feeding, with a gradual in- crease of a dram every two or three days. The intervals of feeding, for children under one year of age, may range from two to three hours. It is rarely advisable to feed even the most delicate athreptic oftener than once in two hours. If the milk can be retained and assimilated in the strength of one-fourth milk and three-fourths barley with 5 per cent, sugar, or if an equal quantity of milk and sugar-water alone is found to agree, 110 THE PRACTICE OF PEDIATRICS the child will begin to grow and general improvement will rapidly fol- low. If the cow’s milk is not well borne, skimmed milk or a weak cream mixture dram of cream to a feeding—may be tried. It is practically impossible to have whey made properly outside of a hospital laboratory or an intelligent home. In using whey one may give it in quantities suitable to the age of the patient. The prescribing of cream among the poor is a hazardous procedure, for the cream may be old, improperly cared for, and swarming with bacteria. If there is a tendency to looseness of the bowels, the diarrhea is thus made worse. Cream mixtures rarely succeed as foods for athreptic children. Cream should be prescribed only among those who can properly care for it (p. 66). Evaporated and unsweetened milk may, however, often be used with suc- cess. Sweetened Condensed Milk.—For the out-patient athreptic and for some in better circumstances the much abused condensed milk fulfils a useful function. It is one of the cleanest foods we can give the dis- pensary baby. It is the cheapest, the most easily kept, and the most easily digested milk that can be furnished him. Consequently, when ordinary milk feeding is impracticable or when it disagrees, one may give condensed milk, beginning with \ dram, which is added to the barley-water or to the plain water for every second feeding, later to every feeding, increasing the quantity gradually as the child shows an ability to digest it. The patient must be seen frequently and the stools carefully examined in order that an increase in the food strength may be made as soon as conditions allow. The mother should be told to bring the napkins to the dispensary, and the child should be weighed at each visit, every second day. It is most gratifying to see how well some gain in weight, not because they are getting an ideal food by any means, but because the food used temporarily fits the case. Condensed milk is thus used as a stepping-stone to something better. When the child has taken condensed milk with benefit for a month or six weeks, ordinary milk is attempted if the time of the year is between October and the following June. After June 1st one may continue with condensed milk, as the possibility of some degree of anemia and rachitis as the cooler months approach is to be preferred to the risk of attempting cow’s milk feeding, with poor milk, in the hands of an overworked or ignorant mother. In beginning the use of ordinary milk, in order to avoid sudden radical changes it is well to replace one feeding of the condensed milk mixture daily with one feeding of a weak plain milk mixture. In some cases this will produce illness and must be stopped; in others it will be well borne. When it is found to agree, two feedings should replace two condensed milk feedings daily. In this way, by increasing by one the number of plain milk feedings every third or fourth day, entire plain milk feeding may safely be inaugurated. The strength of the plain milk should not, of course, correspond to that suggested for well babies. To a child of six months a three-month formula may be given. As the child improves, the strength of the milk may correspondingly be increased. In this way a great many tenement athreptics have been successfully treated. Some children will be able to take and properly care for only two plain milk feedings daily; others will take every second feeding of plain MALNUTRITION IN INFANTS 111 milk. One patient aged fourteen months would take two plain milk feedings daily with comfort, but when the third was given he was inva- riably made ill. Some will not be able to take a particle of ordinary milk. When this is the case, the condensed milk should be combined with a gruel, such as oatmeal, which contains a high percentage of protein. These cases may also be given beef juice at a very early age. Pure cod- liver oil, from 15 to 30 drops of which may usually be taken three times daily without disturbance, may also be given. The tenement athreptic is to be given the benefit of as much fresh air as possible. He is also to be given the advantage of the daily tub-bath and the oil rub. For further suggestions, see Common Digestive Dis- orders of Infancy (p. 99). MALNUTRITION IN INFANTS Malnutrition may profitably be considered as the first stage of ma- rasmus. Every child with marasmus must first have undergone a longer or shorter period of malnutrition. Victims through inheritance, such as those who are constitutionally inferior, the offspring of the tuberculous, and the remotely syphilitic, often show signs of malnutrition, are in- herently weak, and possess low vital resistance. Frequent child-bearing may be a predisposing factor—the fourth or fifth child, when the preg- nancies have been close together, may show general lack of vigor. Symptoms.—With malnutrition the infant may be 3 or 4 pounds underweight, his gain being slow and irregular; often inappreciable, or, at best, a few ounces a week. The muscles are soft, and if the con- dition persists, bone changes, indicating rachitis, soon appear. The child is pale and usually thin. There is a secondary anemia. Dentition is delayed. The hands and feet are apt to be cold and the skin is dry. Excoriations of the buttocks and intertrigo are of common occurrence. The patient shows evidence of .indigestion by a distended abdomen and stools that are far from the normal. There may, however, be no intestinal derangement whatever, the malnutrition being due to the fact that the child’s diet for months has consisted of food that did not contain the nutritional elements required, or the fact that he was unable to utilize that which had been given him. Illustrative Case.—A case due to high fat feeding was that of a male, six months of age, weighing 13 pounds, a resident of a New York suburb, where the conditions are most healthful. His fontanel was slightly depressed, the muscles were soft and flabby, and the ribs were beaded. The child had lost his appetite and suffered from con- stipation. A history of the feeding showed that he had been getting a cow’s milk mix- ture containing approximately 6 per cent, fat, 4 per cent, sugar, and 2 per cent, protein. His indigestion, loss of appetite, and constipation was unquestionably due to the high percentage of fat. The energy exerted in digesting the food almost counterbalanced the benefit derived from it, the result being a very slow gain in weight. Diagnosis.—Upon assuming the care of one of these infants one must invariably make a very thorough examination in order to determine whether there are other factors than that of imperfect gastro-intestinal function. Following the usual physical examination, which should in- clude the ears, the urine should be examined; there should be a von Pir- quet test for possible tuberculosis; there should be a blood-count to learn the degree of anemia and the possibilities of occult pus, and if the case 112 THE PRACTICE OF PEDIATRICS is very persistent, a blood-culture should be made, as it not infrequently occurs that a hitherto unsuspected cause of malnutrition may be bac- teremia. In hospital cases the pneumococcus, the streptococcus, and the staphylococcus have been found in the blood of malnutrition babies. Treatment.—The management of malnutrition due to most causes consists in correcting the digestive errors, in using castor oil or calomel with stomach washing, and in adjusting the food to the child’s require- ments and digestive capacity. These cases are all difficult to feed satisfactorily. The problem which confronts us is often most difficult of solution. Chapin is an advocate of the use of cereal gruel as a milk diluent, claiming that the milk is rendered more easily digested because of the presence of the starch. Others believe that the use of alkalies and ant- acids renders the milk easier of digestion. In very few of these difficult cases, however, do the ordinary cow’s milk dilutions and adaptations produce satisfactory results. The majority of such infants cannot digest cow’s milk unless it is materially changed by other than mechanical methods. It is also to be remembered that in difficult feeding the food helps to solve only a part of our problem. The physical condition of the child, his care, and particularly the containing and working capacity of the stomach, are matters requiring thought and adjustment. A difficult feeding case requires: 1. Fresh air. Indoor airing in winter or roof treatment—cold air. 2. Clothing sufficient to insure warmth; particularly must the ex- tremities never be cold. 3. Quiet—absence of handling other than is necessary for clean- liness. Quiet is particularly necessary if there is a tendency to regur- gitation or vomiting. 4. Stomach washing—a most useful procedure, even when there is no vomiting. A stomach lavage cleans out the mucus and undigested material from the stomach, which is very apt to be enlarged and of de- fective motility. The lavage may be used daily for a week or less fre- quently—perhaps every other day. In some cases one or two wrashings suffice. In others lavage is continued at intervals determined by the condition—rarely longer than three to four weeks. 5. Position. In the cases wdth habitual regurgitation the position in which the child rests in the crib is important. Smith and Le Wald1— as a result of six Roentgen ray studies of infants after feeding—advise the erect position after feeding, the child being held against the nurse’s shoulder for a few moments. When the child is placed in the prone position, the head of the crib should be considerably elevated. Both of these proceedings aid in the expulsion of gas, which they proved is swallowed during the act of nursing. Two methods that have been particularly useful in nourishing these infants are malt soup feeding, and the use of appropriate dilutions of evaporated milk combined with a cereal diluent containing a low percentage of sugar. Both methods have been discussed (p. 78). For many infants dry milk has proved easily assimilable when car- bohydrate and fat have been poorly tolerated. 1 Amer. Jour. Dis. Child., vol. ix, pp. 261-282. IDIOSYNCRASY TO COW’S MILK 113 For the more advanced cases of malnutrition in infants the treat- ment outlined for actual marasmus is indicated (p. 106). IDIOSYNCRASY TO COW’S MILK Rare cases are encountered in which there exists an intolerance of cow’s milk or any form of food which contains cow’s milk, including condensed milk and all the malted foods containing desiccated cow’s milk. In such cases the use of any of these substances as foods produces illness of such an alarming type as to necessitate prompt discontinuance of the food. The only hope for infants thus constituted is a wet-nurse. This extreme reaction to milk constitutes what is known as milk allergy, or milk protein sensitization. Instances of breast milk allergy are reported.1 Illustrative Cases.—Case 1.—An illustration of allergy to milk foods occurred in the senior author’s own family. A healthy, full-term female infant whose birth weight was 7 pounds, 12 ounces was nursed by her mother with indifferent success for two weeks, when the supply failed absolutely. Feeding with a most carefully prepared modified cow’s milk was begun. The child refused the food, and 2 drams were forced. This was followed in a few moments by vomiting and retching, which continued at intervals for twenty-four hours, with collapse and exhaustion to an extreme degree. A wet-nurse was secured, the breast was well taken, and the milk agreed perfectly. In three days the wet-nurses’ milk began to fail and was entirely lost in twenty-four hours. A weak dilution of condensed milk was then given, with results almost as disastrous as before. The child at this time weighed 6 pounds, 4 ounces, and showed all the symptoms of early marasmus. A second wet-nurse was secured, whose milk also failed in a few days. Before her departure, however, a third nurse was engaged, on whose milk the child thrived most satisfactorily. When the patient was three months of age a weak cow’s milk mixture, prepared by the Walker-Gordon Labora- tory, was given. The child refused the food, and \ ounce was forced. As on the previous occasion, vomiting with prostration bordering on collapse was the outcome. Vomiting continued at frequent intervals for twelve hours, and the breast was refused for twelve hours longer. The giving of cow’s milk was not again attempted until the child was nine months old, a wet-nurse meanwhile being employed. The child was then strong and vigorous, and weighed 18 pounds. Two drams of cow’s milk mixture suitable for a baby three months of age were given. This produced nausea and vomiting, as though an equal quantity of syrup of ipecac had been given, but no more serious disturbance. At this time the wet-nurse’s milk began to fail. The breast milk nutri- tion was supplemented by the use of cereal made into a thick gruel. Oatmeal in the form of a gruel to which sugar was added was given, largely because of its high protein content. Beef juice, scraped beef, and pure cod-liver oil were also given about this time. At the completion of the first year a portion of a soft egg was added to the diet. Zwieback and bread crusts soaked in sugar-water were also used. These solid sub- stances were given two or three times a day, after which the child was nursed. Pure cod-liver oil was given almost continuously during the second year. Butter-fat could be taken without inconvenience at one year. Following out the above lines of treatment, the child was weaned when thirteen months of age. She was then fed with an entire absence of cow’s milk from the diet. When six years of age her weight was 55 pounds, height 48 inches. She was normal in every respect, but 6 ounces of milk given at one time would produce a coated tongue, foul breath, constipation, and excessive irritability which was entirely foreign to her nature. At the twelfth year the intolerance for milk was entirely overcome. Case 2.—The young mother of a vigorous, eight-month-old breast-fed girl deter- mined to wean the baby. The family physician prescribed a suitable formula. The child refused to take the milk mixture. A small quantity was taken and immediately vomited. After further unsuccessful attempts at feeding 2 ounces were forced. This was at 10 a. m. The child did not vomit, but passed into a condition approaching collapse. A few hours later she presented the appearance of a case of severe intestinal intoxica- tion. She was very apathetic, but could be aroused with difficulty. The pulse was 1Weil, Jour, des practiciens, September 20, 1920, and MMecine, August, 1920. Starck: Anaphylaxis to Breast Milk, Archives de medecine des enfants, Paris, Septem- ber, 1921. 114 THE PRACTICE OF PEDIATRICS small, very soft, and thready. The respiration was superficial, but not rapid. The eyes were sunken, the skin blanched. In spite of active stimulation and external heat the child grew gradually weaker, making but temporary response to stimulation, and died seventeen hours after the milk had been given. The case was one of anaphylactic shock from the milk protein. Of many cases of allergy to foods, this case alone proved fatal. Case 3.—A boy treated for colitis gave a history of allergy to milk. The placing of a few drops on his tongue would be followed immediately by intense general urticaria. Case 4.—A vigorous, nine-month-old breast baby was given a feeding of cow’s milk and vomited it at once. In a few days another feeding was attempted. The child took only a swallow or two of the food, but at once developed general urticaria. The ears suddenly became several times their normal size, and the eyelids swelled and closed the eyes. The respiration became greatly impeded through edema of the glottis to the extent that the mother feared the child would suffocate. Six hours later the voice was still hoarse and croupy. Three weeks later 5 drops of milk were placed on this baby’s tongue. In three minutes he vomited and became decidedly pale; in a few minutes more he vomited again. This was followed by hiccup, which lasted until he left the office one-half hour later. The child, months afterward, was still so sensitive to milk protein that a vaccination with milk would produce at the site of the scarification a large urticarial wheal. The wheal was also produced by egg-white. Case 5.~An eight-year-old perfectly developed girl had never been able to take cow’s milk in any form. The cutaneous test induced a marked reaction, and all attempts at immunization failed. SCURVY (SCORBUTUS) Scurvy in infants was first described by Glisson in 1651. It was not well recognized, however, until Moller described it again in 1859, viewing the disease as an acutfe type of rachitis. Ingelev, of Sweden, recognized a case of apparent infantile scorbutus in 1873, and in the period 1879-82 Cheadle reported several cases. In 1883 Sir Thomas Barlow was able to give a clear demonstration of the clinical features and pathology of this disease, and thenceforth reports of its occurrence were frequent. Infantile scurvy, or Moller-Barlow’s disease, is a very definite affection, and, although the term “scurvy-rickets” still persists, this serves only to emphasize the frequent coexistence in a patient of the two essentially distinct conditions. Etiology.—The age incidence is significant. In a large number of cases we have seen but two over eighteen months of age; the first patient was four years cld, the second an idiot slightly older. Occasionally scurvy oc- curs in infants under six months of age, but this is unusual. Our youngest case was that of a nursing baby three weeks old. In this infant there was a separation of the epiphyses at both wrists. The immediate physiologic cause of the hemorrhagic condition has not been discovered. It seems proved that there is some constitutional error, due to nutritional defect, which accounts for the development of the actual disease. In most instances the nutritional defect may be ascribed to the use of cooked foods. The well-known collective investigation of the Ameri- can Pediatric Society established the influence of foods that had been subjected to the influence of heat. Thus, 10 patients were entirely breast fed, 4 were getting raw cow’s milk, 116 were on pasteurized, sterilized, or condensed milk feeding, 214 were on proprietary foods. So pronounced a factor is cooked food in the production of scurvy that in all cases so fed we invariably give orange juice, 2 or 3 teaspoonfuls daily. The heating of milk invariably removes something from it which is necessary for the prevention of scurvy; nevertheless, such cooking does SCURVY (scorbutus) 115 not interfere with its nutritional properties. This has been demonstrated in hundreds of cases. The undetermined factor is the antiscorbutic vita- min or vitamin C, which is extremely thermolabile in an alkaline medium. Vitamin C is present in greatest concentration in the citrous fruits. Malnutrition is not necessary for the development of scurvy, neither is previous illness a factor of much consequence. In scurvy there are probably alterations in the capillary walls which permit the diapedesis of the red cells. Wright showed that in this disease the alkalinity of the blood may be reduced to a point as low as 35/200 of the normal, and he regarded scurvy as a form of acid intoxication. Pathology.—The two leading features in the morbid anatomy of scurvy are multiple hemorrhages and rarefaction of bone. Whether the atrophy in the bone is or is not a result of the intra-osseous extrav- asations seems uncertain. It is, however, believed that the rarefaction may occur primarily, independent of the hemorrhagic lesions. Although in some instances hematuria is the only prominent symptom, bleeding is usually not confined to any particular site, but may occur under the periosteum, in the bone-marrow, under the skin, under the membrane lining the serous cavities, or from the mucous surfaces. In the bones the most severe lesions are found in the neighborhood of the epiphyses. The lymphoid marrow cells and the osteoblasts are diminished in number, and there is increased porosity of the cancellous tissue. Fractures of the ends of the long bones are exceedingly common. In some cases there is separa- tion of the epiphyses. In one case there were four so-called fractures—two at the shoulder-joint in each humerus, and two at the hips in each femur. Beneath the periosteum are extensive extravasations of blood, which frequently become organized into firm layers of clot. In rare instances hemorrhages occur within the joints. Symptoms.—The first sign noticed is that of evident pain upon manip- ulation of different portions of the body, most frequently one of the legs. The complaint is that the child cries when the napkin is changed, or when he is being bathed or dressed. Further, instead of freely moving his arms and legs, he allows one or more of his limbs to rest, while the others may be moved freely. In advanced cases all the limbs may be involved, and the child makes no attempt at even changing the position of a limb, and cries vigorously when such a change is made. The position taken is that of outwTard rotation of the extremity affected. In advanced cases the involved joint or joints will be swollen. The swelling may involve the entire limb. In a case occurring at the Babies’ Fig. 8.—Bilateral subperiosteal hem- orrhagic extravasations in advanced scurvy. (New Rochelle Hospital.) 116 THE PRACTICE OF PEDIATRICS Hospital the leg, from above the knee downward, was twice the size of the unaffected leg. Upon manipulation the parts are excruciatingly tender. Repeatedly mothers complain that the child who previously has enjoyed attention in the way of handling and holding, prefers to lie quietly in his crib and apparently fears to be touched. While the long bones are usually involved, the other bony parts may be affected. In two children the ribs, spine, and scapula were affected. The extremities were normal. Both infants were about nine months of age. They cried vigorously when they were lifted by placing the hands around the body under the arms. The diagnosis of scurvy was proved by the quick and complete response to orange juice and the use of un- cooked food. A few ecchymotic areas may be found on the skin, but this is un- usual. Too much emphasis is placed upon this symptom, which is not an early manifestation and may not appear for two or three or more weeks after the first manifestation of the local lesion in the limbs. If the con- dition is not recognized, submucous bleeding almost invariably appears, and is characteristic, providing the child has teeth in the upper jaw; the gums in the lower jaw are rarely involved. The gums are swollen, edematous, and bleed readily. Over teeth about to be erupted blood blebs of a dark bluish color may be seen. In the absence of teeth the gums are usually normal. In a very few cases a slight bluish discolor- ation may be noted. It is only in the very advanced cases that the lower gum and teeth will show involvement. Hematuria to a slight degree is present in most cases. In a few in- stances it has been severe, showing macroscopic blood. Blood in the stools is of very rare occurrence. An unusual form of hemorrhage is that occurring in the orbit and producing protrusion of the eyeball. Exophthalmos of this type cured by orange-juice therapy has been reported. Prognosis.—The prognosis is very favorable. All cases recover if a reasonably early diagnosis is made and proper treatment instituted. If there is simply an involvement of a joint, of short duration, the child may be apparently well in two to five days. In cases in which extensive lesions have formed, two or three weeks or more may be required for complete recovery. The longest time under treatment in our cases was three months. Illustrative Case.—A baby eighteen months of age was taken to Dr. V. P. Gibney, who recognized the condition at once and referred the child for treatment. The child had been treated for rheumatism for three months. All four extremities were swollen to twice or three times their natural size, and were swathed in bandages, each saturated with a different lotion or liniment. In this way each liniment was to be tested out and the one that served best was to be selected for all the limbs. The odors emanating from the child were those of a chemical establishment in active operation. After all previous local applications employed and those in use had failed, the child, with complete paralysis of all the extremities, was considered a suitable subject for the orthopedist. In addition to the symptoms described, the gums were bleeding freely. In this case, the most severe we have seen, the progress toward improvement was very slow. There was much extravasated blood to be absorbed and infractions—how many one could not determine—to be healed. Resolution was, however, eventually complete. SCURVY (scorbutus) 117 Studies of the bones in scurvy with the aid of the x-ray show that even in mild cases complete restoration of the normal bone condition is a matter requiring many weeks, even after the patient is, to all ap- pearance, well. Differential Diagnosis.—Scurvy in infants was formerly most fre- quently confused with rheumatism. The age for scurvy—under eighteen months—is not the age for rheumatism. Scurvy is a disease of early infancy, and rheumatism, a disease of childhood. In rheumatism fever is a usual symptom. In scurvy fever is unusual. From poliomyelitis scurvy may be differentiated by the acute pain upon manipulation and the presence of the knee-jerk. Specific epiphysitis may be mistaken for scurvy if the upper extremity is involved. The absence of other signs Fig. 9.—Extensive hemorrhage about the right femur due to scurvy in a neg- lected six-year-old idiot. Fig. 10.—Hematoma about right femur. (Same case depicted in Fig. 9.) (Bellevue Hospital.)* of syphilis, and a negative Wassermann test, will render a differentiation possible. Further, in any case which is doubtful, the use of orange juice will, in a few days, through relieving the symptoms of scurvy, de- termine the diagnosis. This is a perfectly innocent procedure upon any evidence of pain in any of the limbs. Supposed trauma, such as a sprain or a fall, is the interpretation often applied to the symptoms of scurvy. Trauma in infants is most unusual, but possible, and the orange juice treatment test may be re- quired to differentiate. Among the conditions simulated by severe scurvy are to be mentioned osteomyelitis and new growths of bone. In all doubtful cases the .r-ray is essential. Treatment.—Dietetic.—The first step in the treatment is to supply 118 THE PRACTICE OF PEDIATRICS fresh milk for the child, diluted, if necessary, to meet the digestive ca- pacity. Cases in which the diagnosis is made early often recover without the aid of any other measure upon a change from sterilized milk or in- fant foods to raw milk. Inasmuch as the disease is a most painful one, every means possible should be employed toward furnishing early relief. If orange juice is not well tolerated, beef juice may be given, or the juice of any ripe fruit, suitably diluted. The orange juice very exceptionally disagrees with the digestion. A scorbutic child who has never tasted orange juice will take it greedily and beg for more. One teaspoonful may be given at two-hour intervals, 1 ounce at least being given ordina- rily in twenty-four hours. Among other antiscorbutic foods, lemon, tomato, potato, and even turnip are particularly rich in the essential vitamin. Recent investigations have shown that canned tomato juice and even dried orange juice may still retain their antiscorbutic potency. Unless the case is an advanced one, with extensive subperiosteal hem- orrhages and separation of the epiphyses, relief will be noticed in twenty- four hours and an entire cessation of symptoms in from five to seven days. We have seen a few cases entirely relieved at the end of seventy- two hours of treatment. These cases have been those in which the diag- nosis was made very early, the only symptom being the evidence of pain during manipulation of the limbs in bathing or while changing the napkin. The management of more severe cases is the same as that applied to those of milder type. Fresh food, with orange juice or beef juice, must be freely given. The patients should be handled very gently, and only when necessary, as the pain on manipulation of the involved parts is most excruciating. In cases of epiphyseal separation splints should be temporarily applied. RICKETS (RACHITIS) Rickets was described by Whistler in 1645, and again in 1650 by Glisson. The disease has been more wide-spread in countries with cool, temperate climates than in tropical or semitropical regions, where the inhabitants live for the most part out of doors. Similarly, this disease shows a slightly greater tendency to develop during the winter than in the summer. Attempts to define the exact etiology of the condition for centuries uniformly failed. Most of the earlier theories have been reviewed by Dr. R. G. Freeman,1 who found the disease most frequent in institution babies who were fed on breast milk supplemented by arti- ficial feedings of condensed milk. In his opinion both unsuitable food and infection or toxemia from the alimentary tract may be influential causes. Siegert in 1903 expressed the view that rickets was often hereditary, supporting his belief by observations of severe cases in the breast-fed children of rachitic parents. By other authorities, however, rickets of congenital origin was held to be improbable or in any event exceedingly rare. Rickets is a chronic disease of nutrition. Its chief manifestations are in the bones during the growing period. It is peculiar, however, 1 R. G. Freeman, The Etiology of Rachitis, Archives of Pediatrics, April, 1904. RICKETS (RACHITIS) 119 in that a greater part of the structure which goes to make up the infant organism may be involved in the rachitic process, which is in effect a metabolic derangement of wide possibilities. Age.—Rickets may occur at any age after the first month. It usually makes its appearance between the third and the twelfth months. Few cases develop earlier, and congenital rickets is questionable. Etiology.—Italian and negro infants show a decided predisposition. A negro or Italian baby between six and twelve months of age in New York City without some evidence of rachitis is a curiosity. Environment.—Much has been written regarding the etiology of the disease in its relation to climatic and unhygienic surroundings. While such surroundings may contribute to the result, we have yet to be con- vinced that as etiologic factors they are very important except when the conditions preclude outdoor life and sunshine. It is true that we often find rachitic children in unhygienic surroundings, but thousands of others who live under the same conditions do not have rachitis. A child fed on normal breast milk will endure and thrive in an environ- ment that typifies “unhygienic conditions” (a popular term with writers). Dick1 has pointed out in detail that the countries of the globe most free from this disease are those where the inhabitants live most of the year in the open air and in communities free from fog and smoke. The Chinese are peculiarly free from rickets. Diet.—In the treatment of several thousand rachitic children one fact is impressed most strongly: A child suffering from rachitis is suffer- ing from nutritional errors as a result of improper feeding or inability to assimilate a suitable food. We have yet to see a case which will not improve when suitable nourishment can be given and assimilated, regard- less of the age of the patient, provided, of course, there is no other disease. In children under one year of age prolonged feeding of the proprietary foods or sweetened condensed milk has long been considered the most frequent cause of the disease. The next most frequent cause is the feed- ing of a too strong cow’s milk mixture, which produces indigestion and faulty assimilation. Rachitis in the Breast Fed.—Breast-fed babies among the Italians and negroes often have mild rachitis, and an examination of the breast milk will invariably show a diminution of one or more of the nutritional elements—usually the protein. Illustrative Case.—A nursing woman in the New York Infant Asylum had such a free flow of milk that a foster-child was given her to nurse. The children failed to thrive; each made a gain of but 2 or 3 ounces weekly; both developed rachitis, one in a marked degree. Repeated examinations of the breast milk showed it never to con- tain more than 1.5 per cent, fat, 4 per cent, sugar, and 0.5 per cent, protein. We have time and again seen rachitis in breast-fed infants for whom the milk was adequate in amount, but deficient in nutritional elements. These cases will most often be seen from the seventh to the tenth month. After the First Year.—After the first year fewer cases develop, but a late rachitis is by no means uncommon. The development of the disease at one year and after, as in the very young, has been distinctly traceable to faulty feeding and faulty assimilation. 1 Lawson Dick, Rickets, 1922. 120 THE PRACTICE OF PEDIATRICS Not a few cases during the second and third years are due to pro- longed nursing. The senior author has known just two mothers who could nurse their children, and substantially nourish them, by the breast later than the twelfth month. Usually when the breast furnishes the only means of nourishment after the ninth month, beginning rachitis will soon be noticed. The feeding after the first year of an exclusive diet of milk or of digestible starches is not infrequently a cause. Among the poorer classes children during the second and third years are almost always badly fed. The diet often consists of poor milk and poorly cooked Fig. 11.—Late rachitic deformities: Bowing of clavicles, thoracic sulci, lordosis, knock- knee, saber tibia, flat-foot. (Seaside Hospital.) starches. Children thus fed furnish no small proportion of our rachitic patients. Fat-soluble Vitamin.—-The outstanding factor in the causation of rickets is now affirmed to be the lack of the fat-soluble vitamin A, together with an abnormal calcium-phosphate ratio in the diet. Shipley, McCollum, et al.x have shown that, in the presence of a vitamin A deficiency, there are two forms of the disease, depending on the calcium phosphate imbal- ance, one of which is characterized by a low blood phosphorus and a 1 Shipley, P. G., McCollum, E. V., Park, E. A., Simmonds, N., Jour. Biol. Chem., August, 1921, p. 507. RICKETS (RACHITIS) 121 normal calcium content; the other by a low calcium and a normal phos- phorus. They believe that the low calcium type is associated with the occurrence of tetany, whereas the skeletal changes are related to an abnormal calcium phosphorus ratio. A large amount of research by various other observers is being contributed to this subject along the lines of metabolism studies and blood chemistry. Light.—It has been definitely shown by Hess and his co-workers that, although the most important etiologic factor is dietetic, lack of sun- light, particularly the short ray ultraviolet portion of the spectrum, hastens very markedly the onset of rickets. Association with Other Diseases.—The development of rachitis bears no relation to other disorders, except in its influence upon the nutrition of the patient. The coincidence of scurvy with rickets is not unusual. Theories of Pathogenesis.—Deficiency of lime salts in the system, either as the result of poor food or faulty assimilation, has been long regarded as the cause of the disease, but evidence that rachitic subjects present the supposed variations from the normal, either in alkalinity of the blood or in lime elimination, is still incomplete. Experiments in depriving young animals of fat have failed to render them rachitic. Attempts at bacterial inoculation have likewise afforded no convincing results. Monti, of Vienna, was able to demonstrate a diminution in hydro- chloric acid associated with an excess of lactic acid in the stomachs of af- fected infants, and he coupled with this discovery the observation that the disease was more prevalent among the breast-fed infants of Saxony, whose mothers received little salt in their food, than in communities where the individual intake of sodium chlorid was normal. Hirschfeld demonstrated the existence of a vasoconstrictor substance in the serum of rachitic infants. To the presence of this substance he ascribed the frequent coexistence of simple rickets with tetany, eczema, and such catarrhal conditions of the mucous membranes as are indicative of a so-called exudative diathesis. Sweet1 has attributed the disease not to a deficiency of fat-soluble vitamin, but primarily to a lack of fresh animal food conveying suitable protein, and secondarily to endocrine dysfunction. In the state of confusion arising from so many diverse theories we may summarize the results of clinical evidence in only a few facts: Rickets is infrequent in the breast fed unless colored or Italian; rela- tively infrequent amid good hygienic surroundings; rare before the age of three or four months, and uniformly absent from infants who have been taking and assimilating a substantial, well-proportioned food and live in the open air and sunlight. Pathology.—The most obvious changes are in the bones. Here there is indeed a marked deficiency of lime salts. The formation of bone is interfered with not only at the epiphyses but also in the region sub- jacent to the enveloping periosteum. In the epiphyseal ends of the long bones there is an excessive pro- liferation of the cartilage cells, and an abnormal vascularization of the zones of proliferation and calcification, which intervene between epiphysis 1 Sweet, Brit. Med. Jour., December 24, 1921. 122 THE PRACTICE OF PEDIATRICS and diaphysis. The deposit of lime salts in the cartilaginous matrix is imperfect, and the solid cartilage undergoes a variable amount of Fig. 12.—Epiphyseal evidences of active rickets in the bones of the legs, (Bellevue Hospital.) absorption. As a result of these changes the epiphyses are softened and enlarged and the bones are subjected to varying deformities. Fig. 13.—Multiple fractures of the bones of the forearm with marked epiphyseal en- largement and defects in calcification. (New York Nursery and Child’s Hospital.) Associated with the defective development at the epiphysis there is likewise incomplete formation of bone beneath the periosteum. This membrane is thickened, and the subperiosteal layer of bone, which nor- RICKETS (rachitis) 123 mally undergoes calcification, is vascularized, soft, and deficient in cal- cium salts. “The pathologic changes may be summed up in the statement that there is excessive absorption of the bone with impairment of the process of calcification.”1 When the disease subsides, the imperfect bone under- goes calcification and hardening, but retains the deformities previously acquired. The enlargement of the epiphysis characteristic of rickets is usually first apparent at the costochondral joints, which acquire the well- known beaded appearance suggestive of the title rachitic rosary. In the more advanced cases the thorax undergoes actual distortions, de- fined by the terms Harrison’s grooves and pigeon breast. Curvatures of the spine and pelvic deformities which may be combined with lordosis Fig. 14.—The teeth in rickets. (From Dick, “Rickets.”) are common. In severe cases the legs become curved, owing to the in- ability of the bones to sustain the weight of the body, and portions of the cranial vault may undergo a variable amount of absorption. Local- ized areas of thinness in the occipital and parietal bones are characteristic of the craniotabes of rickets. The affected skull is large and the centers of ossification of the frontal and parietal bones are marked by hyper- ostoses or bosses. In many instances the anterior fontanel instead of becoming closed at the twentieth month remains patent until the third or fourth year. The eruption of the teeth is uniformly delayed. Figure 14 shows the normal calcification of the two sets at various periods, the parts normally calcified in the first two years, and the commonest form of rachitic hypoplasia. (See p. 38.) 1 Adami and Nicholls, Principles of Pathology, vol. ii, p. 1009. 124 THE PRACTICE OF PEDIATRICS Although rickets is fundamentally a disease of general nutrition, the lesions, apart from those occurring in the osseous system, are of relatively slight significance. The spleen is frequently enlarged; less often, the liver. The stomach and colon may be dilated. The muscles undergo wasting, slight degenerative changes, and a variable amount of fatty infiltration. The ligaments are relaxed. The blood shows the existence of a secondary anemia and a mononuclear leukocytosis. The changes, aside from those of a secondary anemia, relate to the content of calcium and phosphorus in the blood. During active rickets either the calcium or phosphorus,1 or both may be markedly decreased. There is no question of the presence of a negative calcium balance in active rickets. In the older cases the calcium balance varies, but during convalescence there is a definite retention of calcium. Fig. 15.—Thoracic deformity and enlarged abdomen of rickets. (Bellevue Hospital.) Symptoms .—In a vast majority of the cases there are no symptoms depending upon the presence of the disease. There may be sweating of the head, restlessness, constipation; but these symptoms are also present in cases which show no rachitic change. There is usually mal- nutrition, and yet malnutrition may be present without rachitis. Rachitic children are unusually susceptible to catarrhal conditions of the res- piratory tract and they have a weak resistance to infection of the in- testines; yet, again, we find these conditions in children who do not have rachitis. In rachitic children there is pronounced lack of nerve balance, and this occurs in children who do not have rachitis. All these con- ditions are present in rickets, and as a symptom-complex they point to rachitis. Such symptoms, therefore, are not diagnostic without further corroboration. Most of the conditions enumerated may be considered secondary to, rather than characteristic of, the disease. 1 Howland, J., and Kramer, B., Amer. Jour. Dis. Child., 22, 105, August, 1921. RICKETS (RACHITIS) 125 So far as the pathognomonic symptoms are concerned, which means the conclusive manifestations of a disease, there are none. The signs proving rachitis comprise the physical appearance of the child, the findings upon physical examination, and the evidence dem- onstrated by the z-ray and by postmortem examinations. Diagnosis.—In a well-marked case inspection shows a condition that is seen in no other disease. There is the large head, cuboid in shape, flat on the top, due somewhat to the exaggeration of the frontal and parietal eminences. The beading of the ribs stands out plainly. The chest is narrow, retracted at the sides, and increased in the anteroposterior diameter, producing the so-called pigeon breast. In pronounced cases there often is an axillary groove extending the length of the chest. A rare deformity is the funnel chest, in which there is a marked retraction of the lower portion of the sternum, greatly decreasing the anteroposterior diameter at this point, with a corresponding increase in the lateral di- ameter. The epiphyses of both the upper and lower extremities are enlarged, and there is a decided outward curvature of the tibia. There may be anterior bowing of the femur. The radius and ulna may also show Fig. 16.—Rachitic head, Harrison’s grooves, and "pot belly.” (Bellevue Hospital.) curvature, but this is less usual. Knock-knee is present in a compar- atively small number of cases. The child has a pot belly, often with umbilical hernia. The liver and spleen are enlarged. Physical examination reveals a large fontanel, two or three times the size normal for the age. Dentition is delayed; repeatedly infants of a year and over will not have erupted a tooth. Craniotabes, which consists of soft, compressible areas in the skull showing deficient deposit of bone-cells, is present in many young rachitic infants. A non-angular posterior spinal curvature involving several vertebrae will be found in a majority of the patients under fifteen months of age. This is due to muscle and ligament weakness, as will be proved by suspending the child by the arms, when the curvature will usually dis- appear. This straightening may not completely take place, in older children, in whom the deformity has existed for several months. Fur- ther, in older cases there may be associated lateral and rotatory curva- tures. The clavicle may show thickening at the ends, and in severe cases there is frequently seen an increase in the anterior curve. 126 THE PRACTICE OF PEDIATRICS Rachitic children will be found abnormal in other respects. There is usually a secondary anemia. They possess poor resistance to bacterial infection, notably pneumonia, and when such infection or, in fact, any dis- ease occurs the chances of recovery are less than in a normal individual. The vital resources are of a low order. Convulsions may occur upon slight irritation. The digestion is rarely up to the normal for the child’s age. It is to be understood that in this description we have been consider- ing a well-marked case. Hundreds of children show varying degrees of mild rachitis in which the conditions may in no way compromise the individual. Further, it must be appreciated that not every case shows the even distribution of the lesions enumerated. There may be cases with bowed legs or knock-knees, spinal deformity, or enlarged cranium, in which one of the conditions mentioned may be the only sign of conse- quence. Differential Diagnosis.—That confusion arises in differentiating rachitis from cretinism, mongolianism, and hydrocephalus is demon- strated in consultation practice. A clear mental picture as to what con- stitutes mongolianism, cretinism, and rachitis would eliminate confusion without the assistance of a consultant. A differentiation, however, between the large, rachitic head and one due to an acquired hydrocephalus or to a mild degree of congenital hydrocephalus, is not a simple matter, for the reason that when there is hydrocephalus there is usually rachitis. An immediate diagnosis is impossible. It is not unheard of for even competent neurologists to ask for time for further observation before making a diagnosis. The further observation has usually included re- peated measurement of the circumference of the child’s head. A child’s head increases in circumference from birth onward about as follows: During the first year, 4 inches, 3 inches of which is the increase during the first six months; during the second year, 1 inch; during the third year, | to f inch; during the fourth and fifth years, l\ inches. When the rate of growth considerably exceeds these figures it is an indication of hydro- cephalus. A prominent fontanel and ununited sutures indicate hydro- cephalus. (See p. 550.) Other diseases occasionally confused with rickets in making a diag- nosis are scurvy, rheumatism, paralysis of central origin, chondrodys- trophy, osteomalacia, osteomyelitis, and syphilis. Prognosis.—The prognosis is favorable in so far as the immediate disease is concerned. In early childhood the negative calcium balance becomes reversed. Uncomplicated with intercurrent disease, all cases recover if properly treated. Indirectly, because of the susceptibility to infection and the lack of resistance, rachitis is a large factor in the mor- tality of the young. Cured patients suffer no inconvenience in later life. There is doubtless some shortening in stature; it is difficult to de- termine the effects in this respect, as there are no means of knowing what height the individual might have attained had he not had rachitis. In women at childbirth its baneful possibilities are made prominent in a narrow and contracted pelvis in which the sacral promontory approaches the pubis. Coxa vara is characteristic of the rickets of late childhood and adoles- RICKETS (rachitis) 127 cence. High arch palate and deviated nasal septum are finally to be noted as deformities in many instances—due to past rickets. The prob- lem of prognosis is thus carried into adult life and deserves consideration in other spheres as well as that of pediatrics. Treatment.—It will readily be seen from the foregoing that the treatment of rachitis resolves itself into the adjustment of the diet to the needs of the patient. As growth and normal development cannot take place without protein and salts, and as the history of our cases has shown that these elements, together with fat, are most frequently lacking in the diet of rachitic children, suitable feeding should be our first consideration. Diet of Infants.—Artificial foods usually are deficient in both the fat and protein; therefore these foods should be discontinued. We have seen a vast number of cases that were on cow’s milk feeding of such strength that it could not be assimilated. In such cases a properly adapted cow’s milk formula is the only treatment required. Diet After the First Year.—For those over one year of age not only should artificial food be discontinued and cow’s milk given, but the cow’s milk should be supplemented by a diet rich in nitrogen, composed largely of milk, scraped beef, soft-boiled egg, oatmeal, and wheat gruel. After the second year purees of beans and peas may be added to the dietary because of the large percentage of protein which they contain. The physician must remember that a diet as highly nitrogenous as the child can assimilate is to be given. Unfortunately, many rachitic children can- not take cow’s milk in quantities sufficient to make it of real nutritive value because of inability to digest the fat, the milk being taken without inconvenience when a large proportion of the fat is removed. Skimmed milk contains at least 3 per cent, of the nutritional element much desired, the protein, and makes a valuable addition to the diet. If a dilution of the milk is necessary, oatmeal gruel should be used. Many children of this class who cannot take a full milk diet will take 1 or 2 ounces of butter daily without inconvenience. It is advisable to give rachitic children a moderate amount of fat, as it aids in the pro- duction of heat and thus saves the tissues. Egg yolk is antirachitic. Specific Cod-liver Oil Therapy.—Kassowitz, toward the end of the last century, advised the use of cod-liver oil. Since that time it has been abundantly proved clinically and experimentally, roentgenographically and chemically, that cod-liver oil in sufficient dosage cures rickets and produces healing in the lesions. This is probably due to the large amount of fat-soluble vitamin contained in it. Changes are demonstrable in al- most all cases adequately dosed and under competent radiographic study within a month.1 Before the second year of age cod-liver oil is often a valuable addition to the dietary. In prescribing cod-liver oil we prefer to use the plain oil. In spite of the disgust adults have for cod-liver oil, children usually take it readily. The younger the child, the better the oil will be taken. To delicate children six months of age from 10 to 30 drops may be given three times daily after meals. From the sixth to the eighteenth month from 20 drops to 1 dram may be given three times daily after feedings. 1 Park and Howland, Bull. Johns Hopkins Hosp., November, 1921. 128 THE PRACTICE OF PEDIATRICS After the eighteenth month from 1 to 3 drams may be given at the same intervals. Hygiene.—Brine baths and oil inunctions aid materially and are of great value in improving the child’s condition as a whole. The brine bath (p. 843), which is given at bedtime, is to be followed by an inunction of goose grease, unsalted lard, or cacao-butter. The goose oil or lard is preferred. At least 2 teaspoonfuls should be rubbed into the skin. The benefit derived from the inunctions is largely due to the massage. The rubbing should be continued for at least ten minutes. The muscles of the back and legs should receive special attention. In a few instances the animal fats act as irritants to the skin and produce a fine, papular eruption. The rachitic child should have plenty of fresh air by means either of a fireplace or an open window. On stormy and very cold days he should be given an indoor airing (p. 838), being placed in his carriage or cart and wheeled about the room. To avoid drafts, the window or windows on only one side of the room should be opened. Rachitic children are very susceptible to head colds and bronchitis; therefore, every means must be employed to prevent exposure. As creeping and playing on the floor are the most frequent methods of tak- ing cold, the exercise pen (p. 839) is particularly useful in these cases. Drugs are of little value except as they increase the appetite and the capacity for properly selected foods. The administration of phosphorus is without avail if the deficient diet is continued. Specific medication without proper food and a fair digestive capacity is valueless. With proper food and a fair digestive capacity medication is superfluous, and a child rapidly recovers without it. We have used phosphorus extensively, and have yet to see a single case in which the beneficial action of the drug could be proved clinically. In giving phosphorus the oleum phosphori is the easiest and most con- venient form for administration. One drop of the preparation represents grain of phosphorus. To children under one year of age 1 drop may be given three times daily. To those between the first and second year to 2 drops may be given three times daily after meals. Heliotherapy.—A mass of evidence is now available from numerous sources proving the curative action of the sun’s rays in various diseases. Not only is the cure produced in the bone lesions of rachitic subjects much like that obtained under treatment with cod-liver oil but there is a similar improvement in the phosporus content of the blood as the result of exposure to direct sunlight. Hess and Gutman1 have demonstrated in addition that owing to the filtering out of certain of the actinic rays of the spectrum the passage of sunlight through clothing or window glass inhibits to a marked degree the beneficial action of ordinary sun- shine. Finally it has been shown conclusively that satisfactory curative effects are to be obtained from the quartz mercury vapor light even in the absence of both sunlight and cod-liver oil. Treatment of Deformities.—The deformities of the osseous system, particularly of the spine and long bones, may be prevented—the first, by keeping the child on his back a greater part of the time, and, if the de- 1 Jour. Amer. Med. Assoc., January 7, 1922. RICKETS (RACHITIS) 129 fortuity is well marked, by teaching him to sleep resting on his stomach. When a kyphosis is present the child should be allowed to remain in the upright position but a few moments at a time. Fig. 17.—Saber tibia) of rickets. (Seaside Hospital.) Deformities of the femur, tibia, and fibula occur long before the child attempts to stand, but too early use of the legs, while not necessarily Fig. 18.—x-Ray appearance of bones of legs. Patient shown in Fig. 17. a cause of deformity, may greatly aggravate the existing conditions. For this reason rachitic children should not be encouraged to walk or stand until they have been under treatment for three or four months. 130 THE PRACTICE OF PEDIATRICS Operative measures for the correction of bow-legs are better post- poned until after the third year. If corrected at an earlier period the deformity is apt to return, and the late deformity may be greater than the original one. The use of the braces to correct the deformity of the legs has been of but little assistance, and the use of braces and jackets of plaster of Paris in kyphosis is usually unnecessary. Rest, massage, and exercises directed to restoring power to the weakened muscles have been of value. III. CARE AND NUTRITION IN CHILDHOOD THE FORMATIVE PERIOD Throughout the first year of life nutrition constitutes the main prob- lem in the program of human development. Habit formation has its inception and the adaptation of the growing organism to its environment is in a measure completed during infancy. The expression of individu- ality has only begun. During the period after infancy this new problem is presented and upon the harmonious combining of good guidance with free rein to the rapidly developing faculties that go to make up person- ality depends in no small degree the future of the individual. In the succeeding pages an attempt is made to emphasize the oppor- tunities existing during early childhood not only for the furtherance of good nutrition but also for the formation of habits essential to the well- being of all children irrespective of individual traits. Necessity of Method in the Management of Children.—One whose work in pediatrics is among all types and classes of people cannot fail to be particularly impressed with the fact that some children are the source of an immense amount of trouble, while others of no better health or greater strength cause very little anxiety on the part of their parents. Children differ greatly as regards individual traits and disposition, but these can be fashioned to a great extent by proper management. The more spirited the child, the greater need of method in the care. Many mothers are worn-out, nervous wrecks for no other reason than a lack of system in the management of the daily life of their children. Thoroughgoing and conscientious these women may be, but they repre- sent that large number who have never been taught that certain functions and duties should be performed only at certain definite times every day. Beginning at birth, the baby should be fed or nursed at definite times and at no others. Sleeping should never interfere with the nursing hours. The child should have time for undisturbed repose, and a midday nap should be insisted upon until the end of the sixth year. The definite time for meals, with properly selected food, should be continued through- out adolescence. The child should be bathed at a certain hour and aired at a certain hour. “Runabouts” should have their hours for play and should retire at a definite time every evening. Such a regime is con- ducive to perfect health, consequently to better growth and develop- ment and to a stronger manhood. It is idle to say that many parents, particularly among the poor, cannot conform to such requirements. The poor are just as anxious to do the best for their children as are the rich, and will do this to the best of their ability if reasons are explained to them. If they cannot reach the ideal, they will attain to a higher degree of efficiency by striving. The trouble ordinarily is not with the mother, it rests more with the medical adviser, who is largely responsible for the ignorance of the mother and the resulting harm to her offspring. 131 132 THE PRACTICE OF PEDIATRICS The School.—Education only in the narrow sense belongs to school. Long before the actual acquiring of book learning is begun habits of application, concentration, and simple reasoning processes are acquired. The degree of development of these faculties constitutes a better measure of mental capacity than knowledge of letters or even ability to read or recite. Only exceptionally is there any need for school in the accepted sense of the term before the sixth year of life. Rearing a “good animal” is the first problem of the early years, and this does not preclude the funda- mental training which has already been emphasized. The kindergarten, of course, has its function in developing good habits, promoting association between children, in forming the school habit, and in relieving overworked mothers from responsibility at certain hours. This agency, nevertheless, is not to be regarded as essential to childhood. As a means of dissemination of contagious disease during the danger period before the fifth year the kindergarten, when close supervision in this respect is lacking, is actually to be regarded with disfavor. For all young children school sessions should be short and broken by recess periods. Single sessions should not postpone the noon meal for which inadequate lunch is too frequently substituted, and school work at home should be prohibited whenever it imposes any strain. When possible young children should not be required to climb stairs in the school building. This rule applies with even greater force to the school child who is delicate or has a cardiac defect. The ideal school is the open-air school. To what degree the open-air- school method may promote well-being may readily be learned from the work of Rollier and his associates (p. 26). The private tutor is of value in the exceptional case only when special attention is demanded because of the existence of peculiarities or defects in development which handicap the child with his fellows, or when time lost because of illness (from which recovery has been as complete as possible) must be made up. If a child is to become a great musician or attempt the prodigious in any chosen sphere the demands of child- hood must be recognized as even more insistent than in ordinary cases, and in some way these demands must be satisfied even at the sacrifice of the technical and the artistic. The Summer Camp.—This institution is a development of the past two decades. As a means of promoting out-door life and helpful associ- ation between growing boys and as a preparation for the boarding school or college of later years, the summer camp is of great value. On the other hand, one cannot deny that the influence of a bad, improperly supervised camp may be far reaching in ill effects. Certain rules applicable to all camps of any size may be mentioned: The general sanitary regulations of a good army camp must be rigidly adhered to. The water and milk supply must be beyond suspicion. Provision for isolation and care of the sick in separate quarters should be made. Sleeping tents should be provided with wooden floors. A resi- dent physician or one in the immediate neighborhood should make daily EDUCATION DISEASE PREVENTION 133 rounds with a view to caring for affections even as minor as bad sun- burn. Bathing, particularly, should be supervised. Regular hours for sleep at night and an afternoon rest hour should be enforced. The wisdom of sending a boy or girl to a summer camp before the age of ten or twelve years is questionable. Our advice to parents should be that they themselves inspect the camp in person before making an en- rolment. Physical Training.—Voluntary exercise is a part of the normal life of every child. Play in the open air, with all that play signifies—run- ning, jumping, bicycle riding, ball playing, tennis, swimming, and skating —make for a good physique without the need of gymnasia and classes for postural correction. Aside from the normal play activities and the simple setting-up exercises employed in the modern school, special phys- ical training is not ordinarily required. If indoor exercise must be sub- stituted, the specialized forms of children’s dancing probably offer the most benefit in developing the body symmetrically. Dancing for girls and appropriate modifications of military drill for boys fulfil the demands for beneficial exercise without the sacrifice of fun. The boy and girl scout activities probably meet the developmental requirements of late childhood as well if not better than any other single agency. DISEASE PREVENTION General Safeguards.—The knowledge that because the more common infectious diseases are seldom escaped throughout childhood, and that certain of these diseases frequently assume a severe form in attacking the adult who has no immunity from a previous attack, leads many people even in this enlightened day to advocate the exposure of children pro- miscuously to whooping-cough, measles, and various other diseases. “Unjustifiable” is too mild a term to characterize such a course. It is no less than criminal. Statistics indicate clearly the generally increased susceptibility and the higher mortality during the first few years of life. Statistics likewise show the greatly decreased incidence of such diseases in adult life even among those who have never previously been attacked. Without this knowledge science and instinct together should still dic- tate the fullest measure of postponement of exposure, if not extreme protection against exposure, in the safeguarding of the young. The young child has no place in a crowd. The crowded theater, the crowded department store, the crowded railway train, and even the crowded elevator afford a risk at all times of infection by contact. The mother who appreciates this fact and acts accordingly, who supervises her child’s playmates, and constitutes herself a beneficent detective upon their mention of sore throat, or their paroxysmal coughs will, without giving offence or instilling panic, go far in the safeguarding of her own fold. She must still be on guard against those of her own household. (See pp. 29-30.) Specific Measures.—That means for the eradication of smallpox, diphtheria, and typhoid must be made the subject of publicity campaigns is a commentary on the bigotry and laziness of too many people. As the list of diseases for which preventive specific therapy becomes longer 134 THE PRACTICE OF PEDIATRICS it is to be hoped that these obstacles encountered in the past will no longer block the road. There is no valid argument against the immunization of a well baby against smallpox in the first year of life or his protection against diph- theria at the end of the first year. There is the best of reasons for the application of the Schick test to older children and the best of reasons for typhoid vaccination for children who bathe in public pools or travel with their parents in unsanitary countries. The details of application of the different methods will be considered under discussion of the respective diseases. DIET FROM THE FIRST TO THE ELEVENTH YEAR At the completion of the twelfth month the average well-regulated baby should be weaned and given other nourishment. If bottle fed, he should receive more than the milk and cereals with which most chil- dren are fed. The food suitable for the second year of life and the method of its preparation and administration are subjects concerning which the masses are most profoundly ignorant. A few children at this period of life are underfed, but the great majority are overfed and carelessly given, at improper intervals, unsuitable food, indifferently prepared. Summer diarrhea finds its greatest number of victims among those children over twelve months of age who have been carelessly fed. The Second Summer.—The dreaded “second summer” robs many homes because of ignorant or careless parents. The second summer, approached properly, is hardly more dangerous than any other summer during the early years of a child’s life. It is almost a universal custom, when the child is weaned or given something other than a milk diet, to allow him “tastes” from the table. Very often these tastes comprise the entire dietary of the adult. Milk is often the only suitable article of diet that is given. Eventually not only is the other food selected un- suitable, but it is given irregularly, and supplemented by crackers kept on hand for use between meals. During the hot months the gastro- intestinal tract is least able to bear such abuse and the child becomes ill. Feeding After the First Year.—Usually when the twelfth month is completed we give the mother a diet schedule, with instructions to begin gradually with the articles allowed, in order to test the child’s ability to digest them. Every new article of food should be carefully prepared and given at first in very small quantities. All meals are to be given regularly, with nothing between meals. With many children this expansion of the diet list is attended with considerable difficulty. They are thoroughly satisfied with milk, and refuse all other forms of nourishment. In such cases time and patience are necessary at the feeding time. The more solid articles of diet should be given first and the milk kept in the back- ground. Among the underfed seen at this period of life are those who have been nursed too long and those who have been kept too long upon an exclusive milk diet. A great majority of the cases of malnutrition of the second year are seen in the exclusively milk fed. These children are pale, soft, flabby, and badly nourished. DIET FROM THE FIRST TO THE ELEVENTH YEAR 135 The following is a diet schedule which has proved of value. The mother is instructed to select, from the foods allowed, a suitable meal: From the Twelfth to the Fifteenth Month: Four Meals Daily 7 a. m. : Two or 3 tablespoonfuls of cornmeal, oatmeal, wheatena, hominy, rice (all cooked four hours the day before in water) served with butter or milk and a little sugar.

HABITUAL LOSS OP APPETITE 137 Malnutrition in Childhood ERRORS IN FEEDING In the care of the bottle-fed the most frequent error is overfeeding, or the use of a stronger mixture than the child is able to digest. Par- ticularly is this apt to be the case at the commencement of bottle feed- ing. The amount is usually too large and the intervals between the feedings are almost invariably too short. Children of the same age cannot all be fed alike. Artificially fed babies of equal health and vigor, but of considerably varied size and weight, will require food of approximately the same strength, and the same intervals between feedings; but the larger the child, the greater the quantity of food required. Thus, the quantity given at one feeding for a child weighing 13 pounds at the sixth month will not be sufficient for a child of the same age weighing 16 pounds. Nervous overactive children and those subject to a good deal of atten- tion will require a greater amount of nourishment than the less active children with quiet surroundings. In other words, the active child burns up more food than one less active in order to supply the requisite nervous energy. Keeping the child on an exclusive milk diet until the twelfth month or later is a not infrequent error. As a rule, starch in some form may be added to the food at the seventh month, and should always be added as early as the ninth month. The giving of food other than well-cooked cereals and milk before the eighth month is a mistake made in many households, and a common error from the twelfth month to the third year is to allow the child’s diet to consist largely of milk and insufficiently cooked cereals. Crackers and milk, bread and milk, cake, and fancy crackers often constitute the only articles of diet during this very impor- tant period of growth. The fact that a high protein food is as necessary for proper development now as at bottle age is overlooked. During early infancy milk is invaluable, but it is not sufficient for the demands of older childhood. Milk, eggs, meat, and cereals, such as oatmeal, rich in protein, are absolutely necessary to normal growth. Irregularity in feeding is another frequent error. The child should have his meals “on the minute,” at the same time every day. The lack of observance of this rule will surely result in loss of appetite and indiges- tion. Indiscriminate eating between meals of bread and butter, pastry, or confectionery, if persistently practised, will surely be followed by indiges- tion and malnutrition. Forcing or coaxing a child to eat is a practice always to be avoided. If suitable food is given at definite well-ordered intervals, a normal child will be hungry at those intervals. If he does not eat, something is wrong, and it is our duty to discover the cause of his loss of appetite. HABITUAL LOSS OF APPETITE The child, like the adult, not only requires sufficient nourishment to sustain life, but, in addition to this, an extra amount to supply the de- mands of growth. Proportionate to their size, all growing animals require more food than do those that have reached maturity. The young child 138 THE PRACTICE OF PEDIATRICS is naturally such a very hungry animal that ample feeding is absolutely essential. Therefore, when there is habitual loss of appetite so that the child’s entire life may be unfavorably influenced, we must realize that the condition is abnormal and strive to discover the cause and apply the remedjr. Physicians are often consulted by parents whose children are suf- fering temporarily or persistently from loss of appetite—a condition usually associated with secondary anemia and defective growth. The child apparently is not ill; he may be active and playful, but he tires easily. The sleep ordinarily is sound and refreshing, but the child must be coaxed to eat. Often he will take food only when his attention is diverted by a story or a toy. He usually eats for the entire family, taking a mouthful each for father and mother, and for the cook! Three or four times a day, depending upon the number of meals, this coaxing, entertaining process has to be gone through. Occasionally children with habitually poor appetites for food in gen- eral will have a history of excessive milk drinking. From 3 to 5 glasses of milk may be taken daily and all other food refused. When milk forms the principal or only article of nourishment after the eighteenth month, children will invariably show evidences of malnutrition. They are apt to be pale and sallow, with flabby muscles. The most frequent cause of loss or lack of appetite is too frequent feeding. It is not at all uncommon to see children from two to four years of age who are being fed six or seven times in twenty-four hours, the argument of the parents being that: “The child takes so little food, he ought to take it oftener.” With increasing age, more and stronger food is required at less frequent intervals. In other cases children may not get their regular feedings at such frequent intervals, but are generously supplied between meals with candy, cake, crackers, and fruits. Unsuit- able food may be the cause of a habitually poor appetite. Children of tender age who are regularly fed from the adult table with heavy adult food, often improperly cooked, soon suffer from loss of appetite. Children who are poor eaters usually have the associated ailment— constipation. Too close confinement indoors is not infrequently associated with, if not a direct cause of, lack of appetite. Children who are kept uninter- ruptedly in the house for weeks at a time invariably have poor appetites. Children with stomachs of slow emptying capacity (Fig. 37) are almost invariably those in whom the appetite is habitually poor. An x-ray study of the stomachs of a considerable number of these cases shows residue after a bismuth meal from five to twelve hours (p. 222). Illustrative Case.—A girl five years of age was brought because of habitually poor appetite. Coaxing and forcing were, always necessary. There was a moderate appetite for breakfast. The other meals had to be forced and vomiting at the table frequently resulted. An x-ray study was made, and it was found that there was a food residue after ten hours. The retention was corroborated by the use of the stomach-tube after an ordinary meal. Treatment.—In order to emphasize a point in teaching, when treat- ment is under consideration, it has often been found useful to state, first, HABITUAL LOSS OF APPETITE 139 what not to do. Do not give these children drugs as a means of inducing an appetite until all other means have failed. The only medication that should be permitted is some simple laxative. There must be one evacua- tion of the bowels daily. The aromatic fluidextract of cascara sagrada, from 1 to 2 drams, given daily at bedtime, or from 3 to 5 ounces of the citrate of magnesia, given before breakfast, ordinarily answers well. Fresh Air.—Every “runabout” child with poor appetite should spend at least five hours daily in the open air, regardless of the season of the year. During very inclement weather in winter indoor airing (see p. 838) is a most satisfactory substitute. Diet.—An important step in the treatment is the regulation of the feed- ing hours. A child from twelve to fifteen months old should have four feedings daily (see Dietary, p. 135). Ordinarily, for “runabout” chil- dren from the fifteenth to the twenty-fourth month, four meals daily are necessary, but when there is loss of appetite, three meals at five-hour in- tervals often answer best. After the second year three meals are in- variably the rule unless the child is weak or ill. All feedings should be given at a definite time each day, from which there should be no deviation. Nothing whatever except water should be allowed between meals in the retention cases. The next step, in case these regulations fail, is to place the child temporarily on a markedly reduced diet, no solid food, such as meat, eggs, bread stuffs, vegetables, or fruits, being allowed. Milk, gruels, and broths should comprise the nourishment. When the desire for food returns the regular feeding schedule is to be resumed. The mother must be given the directions both orally and in writing. If the case is one of milk habit, then the milk must be entirely cut off, and broth, thin gruel, dry bread, or zwieback substituted. The mother is instructed to return with the child in two days. In the great majority of instances the report after forty-eight hours is that the child is raven- ously hungry. When such is the case freer feeding is allowed, but under the same strict observance of feeding intervals, with absolutely no feeding between meals. It is extremely rare to meet a case of habitual loss of appetite which will not respond to this simple method. In a large number of cases of failing appetite we have succeeded in restoring the desire for food by removing milk largely from the diet, having it skimmed and given in small amounts, morning and evening, and in reducing the sugar intake to a minimum. Many children get more milk than is good for them, and practically all children get more sugar than they can utilize with benefit. Feeding in the Retention Cases.—When food residue is found to be habitually in the stomach the interval between the feedings must be pro- longed. The breakfast is to be given at 7 a. m., dinner at 1, and supper at (> p. m. Immediately after feeding the child should rest in a recumbent position for one hour, preferably on the right side. But little fluid should be given with the meal. Our schedule in these cases is roughly as follows: Breakfast at 7 a. m., with 6 ounces of milk; 10.30 a. m. a drink of water; 12.30 p. m. usual meal without w7ater, soup, or milk; 4 p. m. milk or water; 0 p. m. usual supper with milk. To bed immediately, or supper to be given in bed. Change of Climate.—Occasionally a child fails to show the least evi- dence of disease and yet will not respond to proper dietetic and hygienic 140 THE PRACTICE OF PEDIATRICS measures. For such a case a change from the city to the country, or from the inland country to the seashore, has been followed by a decided im- provement. When such changes are impossible, or when proper dietetic regulations are impracticable, as with dispensary patients, medication may be of service. Tonics.—One of the best medicinal means of improving the appetite in cases in which there is no delay in emptying and no hyperacidity is a solution of citrate of iron and quinin in sherry wine, 1 to 2 grains of citrate of iron and quinin being dissolved in \ dram of sherry wine and given, well diluted, before meals. This dosage will answer for children over eighteen months of age. For younger children, 1 grain of the citrate of iron and quinin in \ dram of sherry wine, well diluted, may be given. If this is not successful, 1 minim of dilute hydrochloric acid, minim of the tincture of mix vomica, and 2 teaspoonfuls of water may be given at two-hour in- tervals to children over fifteen months and under two years of age. After the second year 2 minims of the dilute hydrochloric acid and 1 minim of nux vomica, in 3 teaspoonfuls of water, may be given at two-hour intervals. There remain also to be considered under this head not a few children who habitually suffer from poor appetite and are below the average in every respect. THE PHYSICALLY SUBNORMAL CHILD In the treatment of the diseases of children the general practitioner as well as the pediatric specialist is frequently consulted regarding chil- dren who are deficient in physical development. They lack endurance and possess poor resisting powers. They are usually underheight, always underweight, and, in short, have so many subnormal physical character- istics in common that they constitute a class by themselves. Normal Development.—The average child, at the various periods of early life, conforms with a certain degree of regularity to the mental and physical development which by long association we have come to regard as normal. Thus a standard may be said to have been established, and it is up to this standard that we expect the growing child to measure. This is what we look upon as the average of physical and mental development. A few children exceed these requirements and are stronger and larger at the sixth month than the average child at the ninth month. Again, older children at the fourth or fifth year may be in every way equal to their normal playmates a year or two older. Abnormal Development.—On the other hand, there are children who are bom with reduced vitality, or who, through faulty management, usually in relation to feeding, have a reduced vitality. Semi-invalid adults almost invariably beget semi-invalid children. If the parents are of average health and of good habits and the debilitated condition of the child is due to faulty management and nutritional errors, the result of proper dietetic and hygienic management is usually prompt and satis- factory. With the persistently subnormal, the offspring of physically en- feebled parents, the results are less satisfactory. Treatment.—By proper regulation of the habits of such a child, as regards all the details of his daily life, a far better adult is produced than if no such effort has been made. In other words, a diet and general regime THE PHYSICALLY SUBNORMAL CHILD 141 of life best adapted to the individual in question will invariably improve the physical condition of that individual. This applies to the strong as well as to the subnormal, to the growing young of the lower animals as well as to the offspring of man. It is the poorly developed, delicate child that we are particularly to consider—the undersized, frail, small-boned child, whose appetite is persistently poor or capricious, who sleeps poorly, tires easily, is usually constipated, who is subject to catarrhal conditions of the respiratory tract, and whose powers of resistance generally are diminished. On assuming the management of one of these children it is absolutely necessary to make a thorough examination, followed in some instances by a few weeks’ observation, in order to become acquainted with the case in its individual aspects, to learn idiosyncrasies, and to eliminate the factor of actual disease as a caustive agent. When we demonstrate to our satisfaction that the child is free from such diseases as tuberculosis, syphilis, and malaria; when we have eliminated by properly directed treatment all causes, such as adenoids, phimosis, vaginitis, or parasitic and irritant skin lesions, which may have had a deterrent influence upon growth; and when we have satisfied ourselves as to the actual condition of our patient, we are in a position to lay down definite rules of manage- ment. Inasmuch as growth and development depend, above all things, upon a properly adapted food-supply, it must be our first step to provide such nutriment as will be most conducive to growth. As growth takes place in all parts of the body through cellular activity, the nutritive elements which promote cell nutrition and proliferation must be important con- stituents of the diet, and among these the proteins are of prime impor- tance; hence in the management of these children a point to be remembered in the adaptation of the food is the necessity of feeding as rich a protein as the child can assimilate. The younger the child, the greater the neces- sity for growth. Regular Weighings Necessary.—An infant should be weighed at reg- ular intervals, and if under one year of age should not be considered as doing even passably well if not gaining at least 4 ounces weekly. When a baby remains stationary in weight the development is invariably abnor- mal. When the weight is stationary or when only a slight gain of 1 or 2 ounces weekly is made, we always find after a few weeks that there is malnutrition in spite of the apparent gain, as will be evidenced by the symptoms of beginning rickets—anemia, the characteristic bone changes, flabby muscles, and a tendency to disease of the mucous membranes. Subnormal infants should be weighed daily at first; then, as improvement takes place, at intervals of two or more days, but never less frequently than once a week during the first year, no matter how vigorous they may become. The weighing keeps us directly in touch with the child’s condition, but since the increase may be in fat alone, an occasional ex- amination of the child stripped is necessary to tell us whether there is substantial growth in bone and muscle. Feeding Infants.—When it is demonstrated that a child will not thrive on the breast of the mother, another breast should be substituted, or an adapted high protein cow’s milk should supplement or replace the breast 142 THE PRACTICE OF PEDIATRICS milk. If the child is bottle fed and it is demonstrated that proper growth and development are impossible on cow’s milk on account of protein incapacity, then a wet-nurse should be secured. When, after the first year, more liberal feeding is allowed, the neces- sity for high protein in the food selected is as urgent as before. This applies to those children who show evidences of late malnutrition, as well as to those whom we have under our care from early infancy. An important element in the diet up to the third year is milk. A child from the first to the third year ought to receive 1 quart of milk daily. Unfortunately, many debilitated children have a very poor ca- pacity for fat assimilation. When given full milk in as small an amount as 1 pint daily, they often develop foul breath, coated tongue, and loss of appetite, or they suffer from frequent attacks of acute indigestion. The milk is necessary, not because of the fat, which can easily be dispensed with, but because of the high percentage of protein which it contains— from 3 to 4 per cent. When this fat exists, the milk is said to “disagree,” although skimmed milk will be taken without inconvenience. Enough sugar may be added to bring the percentage up to seven, in order that the extra sugar may replace the fat for fuel. Skimmed milk with sugar added furnishes a food of no mean order. Too much milk, however, must not be given. When more than 1 quart daily is taken, the desire for more substantial nourishment, such as eggs, meat, and cereals, is removed. Diet After the First Year.—At the completion of the first year, keep- ing in mind the high protein we may give scraped beef, at first 1 teaspoon- ful once a day, in addition to the cereal and milk. If the beef is well borne, and it usually is, a teaspoonful may be given twice a day, and later three times a day, immediately before the bottle feeding. Eggs should be brought into use from the twelfth to the fifteenth month. At first one-half an egg, boiled two minutes, is given mixed with bread crumbs. If well borne, a whole egg may be allowed. The cereals used should be those richest in vegetable protein, such as oatmeal, containing 16 per cent, of protein, dried peas, with 20 per cent, of protein, and dried beans, con- taining 24 per cent, of protein. The peas, beans, and lentils should be given in the form of a puree. If the child during the second year has an indifferent appetite, the quantity of milk should be reduced, never more than 1 pint of skimmed milk being permitted daily for the first week or two. Many subnormal children who apply for treatment after the first year of age have been subjected to as grave errors in diet as are seen among the bottle fed. Starch and milk frequently furnish the only nutrition up to the fourth or fifth year, the starch used being generally in the form of bread, crackers, and ill-cooked cereals. In one case 4 quarts of milk were taken daily by a boy of seven years. In dealing with this class of children—the delicate, undersized, slow- growing class—it is our aim to give as liberal nitrogenous nourishment as is compatible with the digestive capacity of the patient. If, however, the child has had rheumatism, or if there is a tendency to lithiasis, the use of a large amount of meat is contraindicated. For such children the high protein cereals are particularly valuable. THE PHYSICALLY SUBNORMAL CHILD 143 In general, from early life the diet of the delicate child should consist of milk, suitably adapted, with highly nitrogenous cereals added when permissible. Many subnormal children of the "runabout” age who can- not digest milk containing 4 per cent, of fat will easily digest butter-fat spread on bread or potatoes. Used in this way butter constitutes a pro- tein sparer. Oatmeal-water or oatmeal jelly, mixed with the milk, should be ordered at the seventh month. When age allows, the addition of rare meat, poultry, eggs, and purees of dried peas, beans, and lentils should be made. Boxed, "ready to serve” cereals are never to be given; raw cereals are essential which are cooked three hours. While a high protein diet is desirable, other foods are necessary. Green vegetables, animal fats, the ordinary cereals, cooked and raw fruits, are required to furnish the necessary acids and salts, as well as the necessary variety. In short, the ideal diet for a subnormal child is that combination of foods which, while imposing the least burden upon the digestive organs, supplies the body with material sufficient for its needs. (See Dietary, p. 135.) Baths.—On account of the fear that a delicate child may take cold, the bath is often omitted. All children, both the well and the subnormal, after the second week should be tubbed daily; the delicate particularly require bathing. The salt bath (p. 843) is usually advised. The best time for giving the bath is at bedtime, and in order to avoid all chance of ex- posure the temperature of the room should be elevated to 80° F. The temperature of the water may vary. It should never be above 95° F. except for very delicate young children in whom there is a tendency to a subnormal temperature. Even in these cases the temperature of the bath should never be higher than the temperature of the body. For the frail and the very young the bath should not be continued over' five minutes. In bathing children of eighteen months or over, if the phys- ical conditions allow, a distinct advantage will be gained by a reduction of the temperature of the bath while the child is in the water. An im- mersion in water at 90° F., followed by a gradual reduction during the space of five or six minutes to 70° F., should, upon brisk rubbing, be followed by quick reaction. For children after the third year a graduated cold spinal douche has served well. (See The Cold Douche, p. 842.) If the reaction is not good, if the extremities are slow in becoming warm, the reduction in the temperature should be less or none at all. With the very poorly nourished a reduction below 80° F. should not be attempted. Following the drying process, primarily for the benefit of the massage, goose oil, unsalted lard, or olive oil should be rubbed into the skin over the entire body for five to ten minutes. The bath and massage inunction, besides favorably influencing nutrition, are very effective in inducing sleep. Fresh Air.—Subnormal children are usually deprived of a proper amount of fresh air for the same reason that they are insufficiently bathed —the fear of making them ill. All children need an abundance of fresh air both in illness and in health. To the delicate fresh air is even more essential than to the robust. As many hours daily as practicable should be spent out of doors. The time thus spent depends upon the season of the year and the residence of the child, whether in the city or the coun- try. In the city, during the colder months with pleasant weather, the 144 THE PRACTICE OF PEDIATRICS child should spend at least five hours daily in the open air, dividing the day into two outing periods—from 9 to 11.30 in the morning and from 2 to 4.30 in the afternoon. On very cold days (20° F. or below), on stormy days, and on days with very high winds the child should be given his airing indoors. He is dressed as for out of doors, placed in his carriage, and left in a room, the windows on one side of which are open. Not infre- quently during February and March subnormal children will be pre- vented from going out of doors for several consecutive days. If some means for a daily systematic indoor airing is not provided, these children will often go backward, no matter how excellent the other management. The first symptoms are loss of appetite and the ability to assimilate food. In private work among athreptics, the child has been placed in the baby carriage or in a basket and allowed to rest before an open window for ten or twelve hours of every twenty-four, with a hot-water bottle at his feet. Here he has been fed, being removed only temporarily to warmer quarters for a change of napkins. Sleep.—'The subnormal child requires no more sleep than does the strong, and the rules governing this function at the various periods of life are the same both for the strong and for the weak. (See Sleep, p. 28.) The sleeping-room should always communicate with the open air by a window, either directly or through an adjoining room. A satisfactory means of ventilation is the window-board (p. 26). The child should occupy the room alone, if possible, sharing it neither with an adult nor another child. This ruling applies to all ages, but is particularly neces- sary after the second year. The Nursery.—The temperature of the nursery, day or night, should never be above 70° F. during the colder months. Very young infants, and those who are with difficulty kept covered, should not sleep in air below 65° F. Subnormal children of the “runabout” age are very susceptible to colds. In the management of such children it is necessary to use every precaution against exposure. The most frequent way of exposing a child to cold is by allowing him to sit on the floor. To keep the child of ten months to three years of age off the floor during the winter months, and thereby to eliminate this means of exposure, is very difficult. In fact, with active children learning to walk, or who have just learned to walk, it is practically impossible under the usual conditions. During the colder months there is always a current of cold air near the floor, and allowing the child to creep in winter, even if the floor is protected by rugs and car- pets, is one of the surest ways of permitting him to take cold. If he is allowed to walk on the floor, he is very sure soon to sit down. If he is not allowed to creep and walk about at will, he will not get the proper exercise and will show faulty development. For such cases the exercise pen is of immense service. (See p. 839.) After being dressed, washed, and fed, the child is placed in the pen, on a rug if desired. Toys are given him and the door is closed. He can now roam about at will, stand up, sit down, creep or walk without the slightest danger from drafts. Influence of Climate.—Much has been written regarding the influence of climate in the type of case we are considering. According to our ob- servation, this matter does not deserve the attention it has received. THE PHYSICALLY SUBNORMAL CHILD 145 The city child in a well-to-do family is, as a rule, better off for eight months of the year in his own home with its usual conveniences. The benefits attributed to change in climate are usually the result of a change not of climate, but to more fresh air, which is afforded by the larger rooms of the hotel, with its loosely constructed doors and windows; and the fact that, since the parent is desirous that the child shall receive the full benefit of the change, he is kept in the open air for a much longer time than when at home. The air at such a place is more expensive, and consequently more appreciated than the air at home. With sufficient heat and proper ventilation we may make our own climate. It is not to be denied, however, that a change of residence for a few weeks, during March and April, from New York to Lakewood or Atlantic City, is some- times of advantage. From the first of June to the first of October the child should not remain in any large city if removal is possible. The humidity and the heat which may prevail for protracted periods during this time render the city unsafe, particularly during July and August. The seashore for the entire summer is not to be advised. The children who have been sent inland to the country and to the mountains have, as a rule, returned in the autumn in much better physical condition than those who spend the summer by the sea. Clothing.—Thin, poorly nourished children require more clothing than do those physically normal. A fairly good index as to whether a child is sufficiently clad is the condition of his lower extremities. The forearm and hand cannot be relied upon. The legs and feet of every child should always be warm to the touch. As clothing, a mixture of silk and wool next to the skin is most de- sirable. Although less desirable, a mixture of wool and cotton may be used. The linen mesh, often useful for the vigorous “runabout,” is not to be advised. Exercise is to be encouraged, but should never be allowed to the point of fatigue. In large cities all subnormal “runabouts” from three to five years of age should be allowed to walk not more than six blocks in going to the playgrounds. If the distance is greater, the child should ride part of the way, play or walk for a time, and then be placed in the carriage or cart and ride home. Younger children, two or three years of age, should be wheeled both ways and taken out at the park for a run when the weather conditions permit. Midday Nap.—Every day after the midday meal the child, regardless of age, whether two years or six, should be undressed and put to bed for two hours. He should be left alone in the room, and whether he sleeps or not he should remain in bed for the two hours. Entertainment.—Entertaining play is necessary, but every kind of excitement, such as children’s parties, emotional plays at the theater, and rough play with older children, should be avoided. Education.—The delicate child under eight years of age should be taught only to the extent of strict obedience and good habits. In other respects he should be a little animal. There should be no teaching in the ordinary sense of the term, no mental stimulation, until the child is physically able to bear it. When school-work begins, which in this 146 THE PRACTICE OF PEDIATRICS class of children should never be before the eighth year, the studies should be made easy and the school hours short. Such children should never be forced and usually should attend only the morning session. The delicate child should be carefully watched from the time he comes into our hands until he reaches the normal, or until the period of development is completed. While the management as outlined will not always be attended with brilliant results, it will not be in vain. Many lives will be saved, and as a result of their increased resistance stronger men and women will be added to the race. Now and then one meets with a case among the well-to-do in which, because of prolonged faulty feeding or vicious heredity, the vital spark is so low that, fan it as we may, no impression upon it is made. As a rule, these stubborn patients are the offspring of alcoholism and debauch- ery. The patients are thin, anemic infants; they develop into thin, anemic children, and into thin, anemic adults. The subnormal and de- generate are found in all the walks of life, but thejr are especially numerous in dispensaries and in children’s institutions. Much of the work of the pediatrist is with the weakly of the so-called “better class.” His success in the management of these children depends largely upon the home co-operation, and a promise of this should be obtained before taking the case. The parents must be taught that the development of the intellect, the character, and the body go hand in hand, and that a vigorous intellect is rarely found without a vigorous body. They must be convinced that the body is more than a machine. It has delicate organs to keep in repair and supply with energy. It has a nervous organization; it has sensibilities. The normal exercise of all these func- tions demands the normal nourishment of the body. In our experience family co-operation is at times difficult to obtain. The parents have begun well, but soon tired of the extra work required. It is difficult to make the untrained mind appreciate the necessity of continuous careful attention to details in management. TARDY MALNUTRITION AND MALNUTRITION IN OLDER CHILDREN Malnutrition, associated with tuberculosis and syphilis, is not a part of our subject. In the sections on Malnutrition in Infants and Children it may be thought that there is repetition of what is said under the title of The Physically Subnormal Child. While the management necessarily is along the same lines, two distinct types of children are represented. The marasmic and malnutrition infant or young child may be but temporarily delicate. When he recovers he may develop into as normal a specimen of robust childhood as could be desired. The physically subnormal child as he has been described is inherently delicate, and our efforts are toward improving his condition, with the hope, perhaps, but with no great assur- ance, that he will some time become a robust adult. Tardy malnutrition is usually seen in children of the school age, although it may appear any time after the third j'ear. Such children are deficient in weight, in resistance to disease, and in capacity for work; they are pale, thin, tired children. TARDY MALNUTRITION AND MALNUTRITION IN OLDER CHILDREN 147 Etiology.—Cases of tardy malnutrition as well as those of marasmus and infantile malnutrition are seen in all the walks of life, among the wealthy, the so-called middle class, and among the poor. Strange as it may seem, these cases, regardless of the station of life, have two causes common to all, waste of energy and defective feeding. The scion of wealth who is overfed or badly fed—given food which is unsuitable and allowed the promiscuous use of sweets—may develop malnutrition just as effec- tively as the child of the tenement who subsists on fried meats, grocery milk, boxed breakfast foods, and poorly cooked vegetables. Most important factors in these cases are overwork—excessive energy output in school, at work, or at play—and inadequate rest. The child is active from early morning until bedtime at 7 or 8 o’clock. This entails waste of vitality and the organism suffers. Every child until the seventh year should have an after-dinner rest, sleep if possible, for one to one and one-half hours. There should be twelve hours of uninterrupted sleep at night. In all cases errors in the daily life of the patient will be most apparent. There is a painful lack of knowledge among all classes as regards the nourishment required by a growing child. He is fed to satisfy his appetite, and when this is accomplished, the parents believe that their duty is done. How far they fall short of proper feeding is demonstrated daily in out-patient clinics and in private work. Treatment.—The first step in the management of a case of tardy mal- nutrition is to make a study of the gastro-intestinal tract. A great many children develop errors in nutrition because of defective gastro-intestinal mechanics (p. 220), associated with ptosed stomach and faulty intestinal formation making for poor absorption and slow elimination. We have repeatedly seen children from five to ten years of age, with marked malnutrition, gain from 3 to 4 pounds the first month under treatment which consisted simply in inaugurating the midday rest and in giving food that they had a right to demand, properly prepared at definite intervals, providing, of course, that structural abnormalities have been corrected, in case they were found to exist. The school child suffering from malnutrition should be removed from school temporarily, and as much outdoor life as possible should be made available to him, regardless of his station in life. Everything of a strenu- ous nature should be avoided. He should be put to bed early and en- couraged to sleep late. A midday rest for one who shows marked emacia- tion and diminished resistance is absolutely essential. Illustrative Cases.—Case 1.—The following is quite a usual history of an advanced case of malnutrition in a girl, seven years of age, and the treatment is that which we usually employ: The mother brought the girl to the out-patient service at the New York Polyclinic because the child was pale, did not grow, and was always tired—too tired to go to school, of which she was very fond; too tired to play with other children, as had previously been her custom. Her weight was 41 pounds. No food was being taken except on compulsion. There was no evidence of congenital syphilis or tuberculosis. There was a secondary anemia. The child slept in a badly ventilated room; she drank tea and coffee. Cake, pastry, and sweets were her regular diet, and because she did not eat at mealtimes she was allowed to eat between meals whenever and whatever she pleased. The following mode of life and diet was prescribed: She was to sleep in the front room, known as a sitting room or parlor, with a window open at least 6 inches. She was given three meals a day writh nothing whatever between meals. The diet consisted of red meat once a day, 2 or 3 soft-boiled eggs daily, 1 quart of good milk 148 THE PRACTICE OF PEDIATRICS daily if it agreed (and it did agree). She was to have only natural cereals, such as oat- meal, cracked wheat, and cornmeal—each of which was to be cooked three hours the day before it was to be given. Baked or boiled potatoes and one green vegetable were to form a part of the dinner at midday. Stewed and raw fruits and plain puddings with home-made bread and plenty of butter completed the dietary. She was put to bed at 7 o’clock and arose at 7 the following morning. An after-dinner rest in a darkened room for an hour was insisted upon. Before retiring she was given a brine bath (p. 843), followed by brisk drying with a rough towel, after which her entire body was rubbed for ten minutes with olive oil. In one month a radical change had taken place. She had gained 4 pounds in weight. Her color was good. She complained no more of languor or fatigue. She was eager for school. The improvement continued, and in ten weeks she made a perfect recovery. In not every case will results be so prompt and satisfactory. In some a longer time will be required before pronounced results are to be seen. Nevertheless, every child suffering from malnutrition of this type cannot help being benefited more or less by such a regime. Case 2.—A most pronounced case of this type was that of a boy, eight years of age, who presented a most dilapidated picture. He was tall for his age, very thin, pale, habit- ually tired, and had a well-developed habit-spasm. He was restless, active, and played hard when he was not too tired to play. His weight was 591 pounds. The living regime prescribed was as follows: He breakfasted at 7.30 a. m. He was to remain in bed until 10 o’clock in the morning, then be up and about at play as he wished. Dinner at 12.30 was followed by a rest, of one and one-half hours. Play was permitted without particular restraint until supper at 6.30. Bedtime was 7.30 p. m. He improved rapidly and in one month was permitted to arise with the family. From October 12th to May 27th he gained in weight 191 pounds. We have treated a great many of these cases of malnutrition in older children in the same manner by limiting the energy output, and right feeding. A gain of from 2 to 6 pounds a month for the first month or two is the usual result of the treatment. At the same time there is a radical change in the child’s mental attitude and general appearance. Tonics.—The tincture of nux vomica, 4 drops in water before meals, is sometimes given to children whose appetite is defective. One grain of the citrate of iron and quinin in 1 dram of equal parts of sherry wine and water may be substituted. If there is secondary anemia and defective nerve resistance, the following prescription may be given, interrupted by five days free from medication. For a child five to ten years of age: Ib Liq. potassii arsenitis njjlxiv Liq. ferri albuminati 3iv Syr. hypophosphitum (calcis et soda;) 5iij Aquae q. s. ad, 5vj M. ft. Sig.—One teaspoonful after meals in water. During the five days without the medication cod-liver oil may be given. Laxatives.—If constipation is present, olive oil may be given in- ternally, 2 or 3 drams after meals. If the oil is not well taken, or if it disagrees in any way, its use should be discontinued. Liquid petrolatum (aromatic), in to 1-ounce dosage at bedtime, answers well. The dosage may be gradually reduced and later discontinued. ESSENTIALS IN THE CARE OF ACUTE ILLNESS A well child, regardless of the position he may occupy in the social scale, subscribes to a certain living regime, which should be so fashioned as to supply the requirements of nutrition and healthy growth, which means normal development. Thus, he is fed, clothed, and has the benefit of fresh air, exercise, and bathing. When he becomes ill his position tem- ESSENTIALS IN THE CARE OF ACUTE ILLNESS 149 porarily is changed, and in order for us to act to his best interest radical changes must be instituted in order to meet this changed condition as regards appetite, the digestive capacity, and rest. The great majority of the serious illnesses in children are acute in character. Vitality and resistance determine in no small degree the issue of the disease. Every child begins the illness with a definite number of strength units. We must so act as to conserve every strength unit. Our first duty, then, toward the sick child is to place him in the most favorable position to withstand the ordeal through which he must pass. Regardless of the nature of the disease, certain requirements must be fulfilled that apply to all severe illnesses, the general management of which in children is very similar. Patient to Be Kept in Bed.—The patient is to be kept in bed, not held on the lap. The handling of the child, the passing from one person to another, the attempt at entertaining, cause active excitement and waste energy when quiet is necessary. Quiet Attendants.—Attendants who are quiet and agreeable to the child should care for him. In serious disease states—pneumonia, endo- carditis, and the like—but one person, and that the attendant, should be allowed in the room at one time. Clothing.—The clothing should be the usual night clothing to which the patient has been accustomed in health. There is no illness that requires extra clothing for the body when the customary room tem- perature (66° to 68° F.) is maintained. Heavy shirts and oiled silk or cotton-wool jackets are never to be employed, regardless of the nature of the illness. In summer the lightest clothing should be used; for younger chil- dren a thin linen slip with the addition of a napkin is all that is required. Sponging.—The body surface is to be sponged once or twice a day for cleansing purposes, regardless of the nature of the illness. During the hot days of summer the sponging may be repeated several times with advantage. There is no disease of childhood in which the application of water to the skin is a dangerous procedure. On the contrary, it is quite necessary that the skin be so treated that it function actively. Room Temperature.—In winter the thermometer should never go above 70° F. Hot, ill-ventilated rooms depress the vital powers. The child is poisoned by carbonic dioxid; he is made restless and irritable. He uses up nerve force and energy is wasted. A room temperature of 66° to 68° F. is best under most conditions. There are few households which cannot have a thermometer. Ventilation.—There must always be a communication between the sick room and out of doors. A convenient means of ventilation is the window-board (p. 26). Cold Air.—We are not inclined to advocate cold air to the extreme degree advised by some. A wide open window during illness, such as convalescence from acute pulmonary disease, is an excellent measure if the child is suitably protected by a hood and an extra outer garment. When possible, the patient should have the advantage of two rooms, one for use during the day and one for the night. This is of particular ad- vantage in grip and in the respiratory diseases in which there is a possi- 150 THE PRACTICE OF PEDIATRICS bility of reinfection. The room which is not occupied should be aired continually. Drinking of Water.—There is no illness of childhood in which water to drink should not be given freely. If there is any question as to its purity, it should be boiled. Diet.—The digestive capacity of every sick child is lessened; this we all appreciate, the degree of incapacity depending largely upon the severity and nature of the illness. In every illness the food strength should be lessened. This we do not all appreciate. For breast-fed babies this is done by giving water, sugar-water, or some cereal decoction, as barley- water, before each nursing, in amount ranging usually from 2 to 3 ounces. This dilutes the mother’s milk. The nursing baby is satisfied when his stomach is full. He needs as much fluid as usual, but is unable to digest the usual amount of breast milk. For the bottle fed the food strength is reduced by substituting water for a given quantity of the milk mixture. A safe rule to follow is to reduce the food strength one-half by the addition of water. If the illness is a very severe one of intestinal disorder, whether typhoid fever or summer diarrhea, milk is to be discontinued absolutely, and usually cereal decoctions should be substituted. During a very severe attack of pneumonia or scarlet fever milk is to be also discontinued, and cereal gruels given. If the milk must be withheld for several days milk- sugar may be added to the cereal water substitute so that it shall con- tain 5 per cent, of milk-sugar. This is obviously to supply fuel for the or- ganism and spare the protein waste. When the usual feeding is continued gastro-intestinal infection is almost sure to add to the burden of the pa- tient through toxins absorbed from the putrefaction of undigested milk in the gut. The resulting tympanites is a very serious feature in respir- atory and cardiac diseases. Tympanites embarrasses the action of the overworked or diseased heart and interferes with respiration already suffi- ciently obstructed by the processes in the lungs or in the pleural cavity. The carbohydrates leave no by-products to be eliminated by the kidneys, thus lessening the work of these diseased organs, and perhaps preventing their involvement in such diseases as scarlet fever and diphtheria by diminishing the amount of irritation to which they may be subjected. In short, we must allow just as much food as the patient can care for. When we give more we diminish the chances of recovery through added toxemia or by interfering with the vital processes. Protection from Needless Interference.—Regardless of the nature of the severe illness we must conserve vitality by disturbing the patient as little as possible. The various attentions to the child should be given at distinct, but reasonably long, intervals. It is rare that a child will need food or medication oftener than once in two hours during the night— three hours answer in most cases. Food and medicine may be given at the same time. Not infrequently one sees cases in consultation where something is being done to the child every hour in the twenty-four. This would exhaust any well child. What can the effect be upon the very ill but to diminish chances of recovery? Urine Examination.—Nephritis is a complication, and a serious one, that may be looked for in all acute diseases of children. An early recog- nition of this complication is most important. Albumin in the urine is ESSENTIALS IN THE CARE OF ACUTE ILLNESS 151 one of the earliest signs of nephritis, and involvement of the kidneys may be discovered by urine examinations before any of the other signs of nephritis appear. It is a wise custom in scarlet fever and diphtheria, diseases peculiarly liable to nephritic involvement, to examine the urine daily—in other acute diseases with fever, at two- or three-day intervals. This examination is simplified by writing a prescription for 1 ounce of nitric acid (c. p.) and a few test-tubes, which are kept in the sick room. The cold test is sufficient to detect the smallest trace of albumin. When the physician must carry the urine with him or have it sent to his home, the examination is sometimes postponed or otherwise neglected. Bowel Function.—Every nurse or mother is given a standing order that there is to be one evacuation of the bowels daily, and if this does not occur naturally, an enema must be given. Bowel Feeding.—In conditions of collapse in any illness, in coma, and certain gastric disorders particularly, sufficient nourishment cannot be given by the stomach. When such a condition obtains, regardless of the illness, we must resort to colonic feeding (p. 97). Measures to Prevent Suppression of the Urine.—Suppression of the urine is not an unusual occurrence in pediatric practice, and may occur in a wide range of diseases. One of our most successful means of combating this condition is the use of colonic flushings. Prevention of Pyrexia.—High temperature in children, regardless of the nature of the illness, is to be managed by the same methods. The most satisfactory has been the abstraction of heat through the means of hydrotherapy, in the use of sponging and packs (pp. 840-841). It is a pop- ular belief among laymen that cold should not be used in scarlet fever or measles because of some unfavorable influences on the rash. There is no disease of childhood with temperature in which the application of water to the skin does harm. One may use spongings and packs in scarlet fever exactly the same as in pneumonia or typhoid fever. When is elevation of the temperature to be interfered with? What are the indications that necessitate interference? When we have a degree of temperature that causes restlessness, loss of sleep, rapid heart action, with resulting loss of vitality—i. e., wasted energy—then measures to effect reduction should be instituted. This will be necessary in some cases at 103° F.; in others at 105° F. In other words, we should be governed largely by the effects of the temperature upon the individual and not by the reading of the thermometer. If sponging is employed, it is advisable to use 1 part alcohol with 3 parts of water at about 80° F., the skin being repeatedly moistened with the solution, which is allowed to evaporate. In some cases such a procedure is soothing. In others it occasions no little annoyance, in which event it must not be used. Drugs.—Regardless of the nature of the disease, a full dose of castor oil is of benefit at the beginning of the illness. When drugs are used it is essential that no harm shall result. In any illness in a child one requirement is to keep on good terms with the child’s digestive tract. In our medication we must seek to protect the stomach. This may be done by giving much of the medi- cation after meals, using it by preference in capsules, powder, or tablet; or when it is administered between meals, by giving it well diluted with 152 THE PRACTICE OF PEDIATRICS water. When liquid medication is necessary, elixir simplex in small amount is of value as a flavoring medium. Useless syrups are to be avoided. The worst possible custom is the using of heavy syrups for flavoring. The practice of giving the ammonia salts and ipecac, usually with syrup of tolu, to a child with severe bronchitis or bronchopneumonia is wretched: and this is putting it mildly. Stimulation.—Two criticisms of general application relate to the management of sick children. The first is that heart stimulants are used too early and in too large dosage. Second, antipyretic measures are resorted to when such management is not called for. We have already referred to the latter in stating that a child should not necessarily have antipyretic measures used because he has fever with pneumonia, typhoid, or scarlet fever. Neither does he require stimulation because he has ty- phoid or scarlet fever or pneumonia. Regardless of the nature of the ill- ness, our choice of stimulants is very much the same, and our reason for using them is exactly the same—to assist a heart that needs help. (The employment of heart stimulants will be discussed in detail under proper headings in the different chapters.) It will be seen from the foregoing that the treatment of different diseases of children has many features in common, and these essentials must be appreciated by every man in order that he do the best work in treating children. If there is one thing that has been impressed upon those engaged in children’s work, it is the necessity of completeness of detail in manage- ment. We little realize how sensitive the sick child is, how all nervous effort, all untoward influences, cost something. They cost energy and output of vitality which may be sufficient at times to preclude recovery. Family co-operation is necessary for success, and will be best obtained through the confidence and affection engendered by thorough, painstaking work on the part of the physician. The Sick Room.—If there is a choice of rooms for the patient, the size of the room and the means of ventilation are important points to be con- sidered in the selection. During cold weather a room with southern ex- posure, to which the sun has free access, should be chosen. During the hot months of summer, however, the cooler the room, the better, pro- vided the size and ventilation are satisfactory. The furnishings should be of the simplest, only those articles being allowed to remain which are required for the patient. So many of the ailments of childhood are of an infectious nature that only such articles of furniture as can be washed should be used. Curtains, hangings, and plush furniture have no place in a sick room. A plain wooden floor is much better than one that is carpeted. Enameled beds and plain wooden or enameled chairs and fables are best. A painted wall is much better than a papered one. A fireplace is desirable not only for heating purposes but also for ventila- tion. A child ill in a dirty, badly ventilated, overfurnished, overheated room is from the first at a decided disadvantage. The Window-board.—The value of this simple device in the sick room may readily be appreciated. For a description the reader is referred to p. 26. ESSENTIALS IN THE CARE OF ACUTE ILLNESS 153 Written Directions.—If possible, directions for the care of sick children should be given outside the sick room, so that the physician may have the undivided attention of the mother or nurse. These directions should first be given orally and thoroughly explained, and then written out in detail. When the child is crying, and two or three onlookers are talking, the mother or nurse becomes confused and is almost sure to misunderstand or forget important directions. If there is not a trained nurse in charge, the doctor should show the mother or nursery maid how to perform the various offices for the child. One can in a few moments be taught how to read the clinical thermometer, how to give a sponge-bath and an enema, and how to do many other things which the changed condition of the child requires. The use of a croup kettle, which may be needed for croup or bronchitis, should always be explained. The printed form as given below has proved very useful not only in making the directions absolutely plain and unmistakable but also as a great time-saving measure. The expense of printing is but a trifle. Form A represents the front of the slip. A few minutes only are required to fill in the blank spaces. Form B represents the back of the slip; on this the observations of the preceding twelve or twenty-four hours are entered. One chart may be made to answer for twelve or twenty-four hours, and when the case is finished constitutes a complete record secured with the expenditure of little time and labor.

Blood 154 THE PRACTICE OF PEDIATRICS DIET DURING ILLNESS The extent to which the digestive capacity of every child is diminished during illness depends largely upon the age of the child and the severity of the disease. The younger the child, the greater the incapacity. This is fairly constant with all the ailments of childhood, including, of course, those which directly affect the gastro-enteric tract. Reduction in Food Strength. —In a moderately severe bronchitis, with a degree or two of fever, the digestive capacity is slightly diminished and a 25 per cent, reduction in the strength of the food will answer. During the critical stage of a lobar pneumonia the digestive powers are held in abeyance and predigested foods and exceptionally alcohol must sustain the patient. During an attack of measles, scarlet fever, bronchopneumonia or diphtheria in a bottle-fed infant, at the height of the disease, it is a good custom to reduce the strength of the food one-half by the addition of water, to make up for the quantity removed. For ail- ments of lesser severity, such as bronchitis, with a temperature of 100° to 101° F., or chickenpox, or mild measles, one may reduce the strength of the food from one-fourth to one-third. In the event of any mild ail- ment or injury which confines a child to his bed, the food strength should be cut down, for inactivity as well as disease lessens the digestive capacity. Among nurslings and the bottle fed these precautions are particularly necessary. A child with fever is apt to be thirsty and to take more fluid than in health. This is frequently the case during summer diarrhea. In order to prevent taking too much food, one should not only order that the milk be diluted for the bottle fed but also instruct the mothers of nurslings to give a drink of water immediately before each nursing and between nursings, and then to allow the child to nurse only one-half or two-thirds the usual time. For the bottle fed, one-half to one-third the contents of each bottle is to be removed and the quantity replaced by boiled water, so that the amount of fluid given remains the same. If a child is a “runabout” over two years of age he may be given broths and thin gruel—one-half milk and one-half gruel. By carefully watching the stools, thus fitting the food to the child’s capacity, we may avoid grave intestinal complications which, during the summer, often prove to be more serious than the original ailment. In the acute gastro-enteric infections and in typhoid fever all milk must at times be discontinued. The dietetic management of the acute intestinal diseases and typhoid fever is referred to in detail under the respective headings. The Art of Feeding in Illness.—Not only is food often taken in in- sufficient quantity in illness, but in many cases it is absolutely refused. In other cases, during coma and asthenic states, swallowing is impossible. In delirium and in conditions of collapse nourishment must be given, and when this is impossible by the natural method we have, as temporary substitutes, gavage, rectal feeding, and such expedients as intravenous infusion. Forcing the child to take nourishment by the mouth is rarely neces- sary. Coaxing and bribing ordinarily succeed far better. For a child from three to five years of age a bright new penny possesses much per- suasive power. The child will usually take food better from one to whom TREATMENT OF THE INDIVIDUAL 155 he is accustomed, like the mother or nursery maid. The trained nurse should understand that while she is unacquainted with the patient, the simpler needs of the child are to be looked after by others to whom the patient is accustomed. The nourishment should be as palatable as possible and served in bowls, cups, or plates that are attractive to the patient because of color, pictures, or peculiarities of shape. Junket flavored with vanilla, served cold, is a favorite food for sick children of the “runabout” age. Frozen custard and home-made ice-cream, made with one-third cream and two- thirds milk, will usually be well taken. Toast, dry bread, and crackers made in peculiar shapes are attractive to the child. In not a few cases we have succeeded in feeding satisfactorily children two or three years old, when several other schemes had failed, by allowing the temporary return to the bottle, from which they had been weaned for a year or so. In these difficult feeding cases the child’s peculiarities and wishes must be studied. Children in illness require water, but frequently take it in insufficient quantities. Those who refuse plain water wall often take ginger ale, sarsaparilla, or vichy. If these drinks are well taken, they may be given freely. In the acute infectious diseases, especially pneu- monia, free water drinking is a therapeutic measure of no mean value. TREATMENT OF THE INDIVIDUAL In these days of specialization one is sometimes impressed with the fact that there is a tendency for the patient, the individual, to be lost sight of, to be overshadowed by the immediate disease or condition from which he may be suffering. With children the success of the treatment in practically every chronic ailment depends upon the vitality of the indi- vidual patient and his powers of resistance as a whole, to a much greater degree than is the case with the adult. The object of taking up this subject is not to be unkindly critical, but to call attention to one phase of management which is not sufficiently appreciated by many who have to deal with children in their professional work. Not at all infrequently poorly conditioned children, who have been treated for months by local measures for a skin affection, recover without any local treatment whatever (other than an attempt perhaps to relieve the itching) when their lives are ordered according to the requirements of the growing child as regards nutrition, bowel evacuation, sleep, suitable clothing, fresh air, and rational exercise. Cases of chronic rhinitis and bron- chitis which may have persisted for weeks respond promptly when local measures, sprays and douches, and the internal use of drugs are suspended and the child’s life is directed along rational lines. Those who treat tuber- culosis and chronic bone diseases, chronic otitis, chorea, and hysteria, are to be reminded -that their work is not half finished when they have directed the usual daily or weekly routine treatment. In these chronic ailments it is folly to expect what a cure really means (a constructive process) on a destructive diet and improper habits of life. Children possess marked recuperative powers, and the rapidity of progress toward recovery is often most gratifying when right conditions 156 THE PRACTICE OF PEDIATRICS are instituted as relates to these fundamentals in child management, viz., food, sleep, clothing, and bathing. It is the height of folly to give children iron for anemia and allow them every form of indiscretion in diet. It should always be remembered that the best results are obtained in the treatment of a child, whatever the nature of his illness, when he has a child’s normal existence, and it is only under such conditions that' satis- factory results of treatment can be expected. IV. EXAMINATION AND DIAGNOSIS Knowledge of the Normal.—Before a student of diseases of children is shown a sick child he should be made thoroughly familiar with the normal child of approximately the following ages: under three months, one year, three years, five years, and ten years. The student should learn the normal appearance of the eyes, ears, throat, skin, genitals, and the character of the stools of the various ages. He should be instructed in the examination of the liver, spleen, abdomen, heart, and lungs. One who teaches diagnosis in children in postgraduate work is repeat- edly impressed with the handicap under which many physicians work because of a very indifferent conception of the normal. Without sufficient ability to examine the canal and drum of the ear, and to know the possibilities for variations within the normal, it is futile to attempt the recognition of disease processes. Many physicians expert in pulmonary diagnosis in adults are wholly unable to make out even approximately diseased conditions in the lungs of infants and young children. These are all conditions that cannot be taught in a didactic way. Neither can one learn much of the subject through reading. What is required is the examination of the normal infant or young child—not a few examinations, but a very careful routine ex- amination of many infants and young children. Most difficult to deter- mine is the borderland between normal and diseased processes, as evidenced by physical signs. Diagnosis in children requires ability to estimate the condition as a whole. The fact that the patient cannot describe his symptoms is of more advantage than detriment. The child appears in the perfectly natural condition, without attempt to mislead, with no preconceived ideas or the- ories. In other words, the child, unless alarmed, is always natural, always himself; this is a very definite aid. Further, the young child has no imagination. He is never hypochondriac. Instead of giving the im- pression that he is more ill, he is liable to be judged less ill than he really is because of his activities and disinclination to give up. This tendency to remain active may be misleading. When, therefore, a child appears very ill, while the condition may not be dangerous, we may always know that he feels very badly. Physicians who wish to become expert in diagnosis must first learn the normal child from birth until he passes into the adult. First Examination.—Upon being called upon for the first time to see a patient, it is an essential custom in every case to take a history. Below is a copy of a blank history record which has proved of value. Form A represents the front of the slip. Form B represents the back of the same slip. Further records are kept on plain ruled sheets of the same size— 5 by 8 inches. 157 158 THE PRACTICE OF PEDIATRICS HISTORY RECORD FORM A Date Address Name Mr- Age Family History Children living Ch. dead Cause Rheumatism Tuberculosis Syphilis Nervous Dis.

The habit of ob- taining a complete and accurate record of family peculiarities in relation to disease is often of much service, subsequently, if not at the time. Only upon systematic questioning will necessary facts be brought out relating to tuberculosis, rheumatism, and syphilis. The child’s personal history includes the birth weight, the rate of growth, the nature of previous illnesses, present weight, the condition of the skin, eyes, nose, heart, lungs, tongue, bowels, bones, and the temperature. All these points are noted and recorded. It is only by such an examination, requiring much time and patience, that we are able to become thoroughly acquainted with the case in hand. The child must be stripped for the examination. The conditions found are then entered in the proper spaces in the history chart. After the family history has been taken and the general physical examination is completed, we are in a position to devote ourselves to the present condi- tion of the patient. After one has practised for a time, thoroughly ex- EXAMINATION AND DIAGNOSIS 159 amining every new case, he is impressed not only with the value of the method as bearing upon the management of the condition in question, but also with the unexpected pathologic findings in perhaps other organs, particularly the heart, throat, and lungs. Diagnosis by Inspection.—We must learn the appearance and bodily habit of the child under normal conditions. Thus the baby of a few weeks cries when hungry, and with inco-ordinate movements of the arms and legs expresses his discomfort. With colic or pain of any nature he also cries, and with inco-ordinate movements of hands and legs makes known his discomfort. But the child’s manner of crying and the movements of the body are in no way alike. A baby spoiled and who wants to be taken up also makes a great ado, and yet he acts vastly different than when he is in hunger or pain. All the above manifestations are vastly different from the cry and the arhythmic movements of early meningitis. The position in which the child rests in bed often supplies us with very good evidence as to the nature of the trouble. Thus one position is assumed in meningitis, another in paraplegia, and another in scurvy or poliomyelitis. The countenance or the facial expression may be indicative of the disorder. The anxious, flushed countenance of acute pneumonia, with the dilatation of the alee nasi and the rapid breathing and grunt, are all strongly suggestive. The sunken eyes, the expressionless countenance, the ashy pallor, the superficial breathing, all characterize the appearance of the patient with intestinal toxemia. The diagnosis of malnutrition and marasmus is always stamped on the countenance. In cretinism, in Mongolian idiocy, in microcephaly, and other forms of mental deficiency the name of the disorder is written on each countenance, and for diagnosis we need go little further. The blue-white skin of anemia, the pallor of nephritis, with the fulness about the eyes, are often diagnostic in themselves. Among the trans- missible diseases, measles, mumps, and chickenpox are readily diagnosed by inspection. In scarlet fever, also, inspection is our greatest aid. In hemiplegia the quiet arm and leg, with the other arm and leg in motion, are strongly suggestive as to the nature of the trouble. The only way in which whooping-cough may be positively diagnosed is to watch the child during a paroxysm. By inspection we can fairly accurately determine the existence of acute laryngitis or membranous laryngitis. As mentioned elsewhere, the obstruction in acute laryngitis is inspiratory, while in membranous laryngitis it is both expiratory and inspiratory. The position of the head, the dysphagia, and the peculiar cracked voice mark retropharyngeal abscess. The method or peculiarities of locomotion supply most valuable evidences of Pott’s, hip, or other bone and joint disease. In tetany, the “accoucheur’s” hand, and the feet in extreme extension, are all that are necessary for diagnosis. The yellow conjunctive and the tinted skin indicate jaundice. In the skin diseases or skin manifestations of any nature inspection again is an important means of diagnosis. The facial expression due to adenoids is so characteristic that every text-book contains a photograph demonstrating the “adenoid face” (p. 111). 160 THE PRACTICE OF PEDIATRICS Laryngismus stridulus, convulsions, tonsillitis, rachitis, scurvy, and stomatitis are all diagnosed by inspection. It will readily be seen what a great aid in diagnosis is possessed by the physician who has trained powers of observation. Inspection During Sleep.—It is of advantage to observe many chil- dren when they are asleep and beyond all the influences of their sur- roundings. In not a few cases correct respiratory observations are possible only when the child is asleep. V. MORTALITY AND MORBIDITY All figures from which statistical studies can be made with reference to the etiology of disease and the relative importance of the different causative factors are dependent upon accurate tabulation of births and deaths. Only in the more highly developed nations is the recording of vital statistics carried out with requisite accuracy, and even in 1920 the death registration area of the United States comprised all of only 33 States; and the birth registration area (established in 1915) only 23 States. Except in the case of the reportable diseases, and then only when the records of a community are kept fairly complete, we still have incomplete data for the study of the incidence of diseases which seldom prove fatal. Many facts, however, are readily obtainable through the United States Census Bureau records and the reports of health departments in large communities. The physician should keep informed concerning those facts which are fundamental. In the preparation of the following para- graphs compilations by Dr. Philip Van Ingen, of New York, have been freely employed. The death-rate for the first year of life in spite of intensive infant welfare work averages 96.6, while the crude death-rate is 14.6, only one-seventh as high. If the figures for the United States Army in the recent war be taken for comparison, a baby’s risk of life during the first year is disclosed to be eight times as great as that of the soldier for a corresponding period. From 20 to 30 per c ent. of the infant mortality is ascribed to acci- dents at birth or defective developmental conditions operative in the first month of life. No stronger argument could be cited to emphasize the need of responsible obstetric attendants, to say nothing of prenatal care. The following table includes for purposes of comparison the leading disease groups important in determining the mortality of infancy: PERCENTAGE OF INFANT DEATHS AT VARIOUS AGES UNDER ONE YEAR FROM CERTAIN CAUSES Infectious diseases.

MORTALITY AND MORBIDITY 163 Scarlet fever steadily increases in importance with age, reaching its maximum in the fifth year. Diphtheria, like measles, becomes important during the second 3rear and steadily increases through the fifth year. Pertussis becomes important after the first month of life and reaches its maximum in the second year. Tuberculosis steadily increases with each period. Gastro-intestinal disease is of greatest importance after the first month throughout the first and second years. Bronchitis and bronchopneumonia as causes of death exert the greatest influence during the period from one month to two years of age. Nephritis shows a steady increase in importance with age. The influence of scarlet fever on the incidence of nephritis indirectly affects the mortality figures for the latter disease. Through the agencies working to promote better understanding of infant feeding, better obstetrics, and what may be designated by the general term “improved baby hygiene,” a rapid reduction in infant mor- tality in many communities is being obtained. New York City has well illustrated the effectiveness of work along this line.

A fairer idea of progress is obtained by averages than by figures for single years—“Progressive Averages” are averages for three consecutive years, the last figure in each group of 3 being consecutive. Thus 1910 is three-year average 1908-10; 1911 is three year aver- age 1909-11, etc. Throughout this book under the heading “Prognosis” an attempt is made to give some idea of the influence of various specific conditions to which the patient is subjected upon the chances of recovery from a given disease. Only by bedside observation coupled with a knowledge of probabilities dependent on statistical studies is the ability to make fairly accurate prognosis acquired. VI. THE NEWBORN Premature and Congenitally Weak Infants Comparatively few infants born before the completion of the twenty- eighth week of pregnancy survive the first year. Reported cases of sur- vival of those born before that time are usually unreliable, as the reports seldom follow the child beyond the third month. The prognosis is in- fluenced by the factors causing the premature birth. If syphilis is present, the child may survive but a day or two. Children whose births are forced because of kidney disease in the mother do not appear to do as well as others. In children’s institutions we have treated a large number of premature infants and have had anything but brilliant results with them. They not infrequently live to be two, three, or four months of age or older, but on account of reduced vitality they readily succumb to the slightest ailment, a mild bronchitis or fermentative diarrhea being sufficient to terminate their existence. In the management of the premature and delicate newborn there are four points to be considered—the air the child gets to breathe, the nourishment, the maintenance of bodily heat, and the danger of infec- tion. It is also to be remembered that we are dealing with an unde- veloped body which is not ready for the environment in which it is placed. The premature baby should be handled only when necessary, and then in the gentlest manner. Bathing is often best omitted for the first few weeks, oil being used for cleansing purposes. Because of the undeveloped parenchyma of the lungs unusually good fresh air is required. Because of the undeveloped heat centers the body heat of these infants is quickly lost and must be maintained by artificial means. The stomach is small and the digestive processes are undeveloped and weak, so that the nour- ishment should be of the most easily assimilable character. Artificial Heat.—The maintenance of heat is of the utmost impor- tance. For this purpose incubators and their various modifications have been used from time to time. They may, under careful watching, maintain an even temperature, but practically all have been defective in supplying fresh air to the child. Incubator babies invariably are prone to do badly. The padded crib with the child wrapped in cotton and surrounded by hot-water bottles is a safe means of maintaining the temperature. A thermometer should rest between the cotton and the bed-clothing as a guide to the nurses in the use of the hot-water bottles. Ordinarily this should register between 85° and 90° F., depending upon the tem- perature of the child, whose rectal temperature' should at first be taken frequently. If there is a tendency for his temperature to be greatly re- duced—below 95° F.—more external heat will be necessary than if his temperature is 97° or 98° F. Various beds and devices on the market for the premature are rather fanciful affairs, but of no greater service than those perhaps more crude. Means and methods complicated in char- 164 PREMATURE AND CONGENITALLY WEAK INFANTS 165 acter are to be avoided in treating children in the home. Thp best means of maintaining adequate warmth without sacrifice of ventilation is afforded by the premature ward of a hospital. Room Temperature.—The temperature of the room should be main- tained at about 80° F., and not under 75° F. Fresh Air.—Suitable ventilation may be secured by the window- board device (p. 26). Absence of Infection.—Only the nurse and rarely the physician should be allowed in the room. Infection of any nature is a very serious matter. The family generally, and visitors always, should be excluded from the presence of the premature. * Feeding of Premature Infants.—Breast milk for pre- mature infants born under twenty-eight weeks is almost a necessity, and should always be procured when pos- sible for all premature children. The mother, with the rarest exception, is unable to supply it, so that a wet- nurse should be secured. In selecting a wet-nurse for a premature baby it is advisable to take the wet-nurse’s baby also, as the premature infant may not be able to nurse, or if he nurses will not take all the milk. Pumping the breasts of a wet-nurse will almost invariably dry them up if her own baby is not with her to furnish the necessary stimulation of nursing. Sufficient milk may be removed by the breast-pump to supply the premature infant if he is unable to nurse, and the wet-nurse’s baby will empty the breast. For premature babies who refuse the breast or are unable to take a nipple, the Breck feeder (Fig. 19) may be used as a means of giving nourishment; or gavage (p. 853) may be brought into use. To this we are obliged to resort in rare cases. The Breck feeder consists of a graduated glass tube, narrowed at one end. Over this end is placed a small rubber nipple, the other end being closed by a flexible rubber cap. Suction on the nipple is aided and encouraged by press- ure on the air-filled cap. If the breast milk proves too strong, it may be diluted with equal parts of a 6 per cent, sugar solution, from \ to 1 ounce of the mixture being given at first at intervals of from one to one and one-half hours. Fourteen to fifteen feedings may be given in the twenty-four hours, the amount depending upon the child’s digestive ability. If human milk is not obtainable, whey made from whole milk may be given, the nutritional equivalent of which is approximately 1 per cent, fat, 1 per cent, protein, 3.5 per cent, sugar; or 1 ounce of gravity cream may be given with 1 ounce of milk-sugar and 15 ounces of water, which affords a nutritional equivalent of 1 per cent, fat, 5 per cent, sugar, and 0.3 per cent, protein. Evaporated milk (p. 78) is a useful means of feeding in these cases. The food strength is increased, the intervals are made longer, and the feedings larger as the patient proves able to assimilate the food. The premature child requires unusual advantages, and even when Fig. 19.—The Breck feeder. 166 THE PRACTICE OF PEDIATRICS but one month premature, rarely “catches up” during the first year, sometimes not for two or three years. Diseases of the Newborn CEPHALHEMATOMA These tumors are usually situated at the site of the caput succeda- neum, and are composed of blood. Sometimes pressure of the forceps is accountable for their presence, but rarely can any injury be found. During a long and tedious labor the pressure on the blood-vessels of the scalp is increased, and this is thought to be an active cause in the for- mation of these tumors. Blood changes are also cited as a possible etiologic factor. The cause cannot be ascribed entirely to pressure against the presenting part, as we find cephalhematomata in breech as well as in vertex presentations. The hematomata are of three varieties, as shown by Fig. 20. Double cephalhematoma may exist. Pathology.—These tumors are generally situated over the parietal bones. The scalp may show small hemorrhages and ecchymotic areas. The tumor itself is composed of blood. Soon after birth the blood is btScalp ■Periosteum S/iu-lL -Dura mater Fig. 20.—Varieties of cephalhematoma: a, Between scalp and periosteum; b, between periosteum and skull; c, between skull and dura mater. usually in a fluid state, while in later cases coagulation has taken place. The tumor may be infected with pus-forming bacteria and an abscess may result. Symptoms.—At a time varying from the first to the fifth day of life a tumor is seen occupying a position generally over the parietal bones. It is soft, gradually increases in size for about a week, and then dimin- ishes; infrequently a ridge develops around the outer border of the tumor, giving the sensation upon pressure of a depressed fracture. During the latter stage of the tumor a crackling sensation will be elicited on pressure by the fingers. There is no accompanying fever. The child shows no annoyance. The tumor does not pulsate. One must be careful not to confound this condition with scalp edema, as seen in fracture of the skull after severe traumatism. In uncomplicated cases the tumor gradually becomes smaller and smaller, until finally, after some five to twelve weeks, it disappears, sometimes leaving a slightly raised, uneven, bony base. Differential Diagnosis.—Encephalocele occurs along the lines of sutures or at the fontanels. Pressure may cause convulsions. With movements of respiration, the swelling may vary in prominence. Hydrocephalus.—The head enlarges as a whole, showing separated sutures and large fontanels. SCLEREMA 167 Caput succedaneum is edematous, does not fluctuate, and disappears on the second day. Depressed Fracture of Skull.—Depression exists and not a tumor. Prognosis.—In the uncomplicated cases the prognosis is usually good. The prognosis depends upon the amount of injury to the parts and the occurrence of any infection. Internal cephalhematoma with effusion is invariably fatal. Treatment.—These tumors are usually absorbed if let alone. Care should be exercised that no injury may happen to them during handling the infant. No dressing is necessary. In infected cases, where the forma- tion of an abscess has occurred, incision and drainage are indicated. HEMATOMA OF THE STERNOCLEIDOMASTOID This condition is the result of trauma which takes place during de- livery. The muscle is torn as the result of pulling by forceps or manipu- lation on the part of the accoucheur in the endeavor to bring down the after-coming head in breech cases. The injury consists in a rupture of the muscle-fibers and blood-ves- sels. A tumor forms within the muscle sheath, which may be small or large, involving the muscle structure in its entire width. There is al- ways an associated contraction of the muscle, which places the head in the wry-neck position, drawn toward the affected side. The tumor is usually located in the lower third of the muscle. Occasionally it is lo- cated immediately at the attachment to the clavicle. The tendency of these cases is toward complete recovery. The tumor is absorbed, but a shorter muscle is sometimes left, which holds the head in the characteristic position. Treatment.—It has seemed from the observation of a large number of cases that massage hastened the absorption of the tumor. The mas- sage should be practised for fifteen minutes three times a day. At the same time a moderate stretching of the muscle should be attempted by rotating the head toward the unaffected side and upward. All cases eventually make complete recoveries. SCLEREMA Sclerema neonatorum (Underwood’s disease) is a rare affection of early infancy characterized by progressive induration of the skin. Etiology.—The condition may be present at birth. The majority of the cases develop before the tenth day of life. Nearly all the reported cases have occurred in premature infants or those weakened by pre- existing diarrhea or pneumonia. Poor hygienic surroundings are in- cluded among the possible predisposing causes. Pathology.—Parrot described the essential process as a drying up and thickening of the skin, associated with a diminution in the fatty elements of the underlying connective tissue. Langer ascribed the con- dition to a solidification of the fat as a result of low body temperature, a phenomenon more readily possible in the newborn infant than in the older subject, because of the peculiar chemical composition of infant fat and its corresponding property of solidifying at a relatively high 168 THE PRACTICE OF PEDIATRICS temperature (89.6° F.). Other authorities have likened the cutaneous changes of sclerema to those occurring in myxedema. Mensi1 distinguished three types of sclerema, depending upon the degree of atrophy in the skin. In all the forms atrophy of the subcutaneous connective tissue was the chief lesion. Northrup reported a case in which microscopic examination of the skin revealed nothing abnormal. Symptoms.—The chief general symptoms comprise progressive emaciation and asthenia, subnormal temperature, and failing pulse and respiration. The thickening and hardening of the integument begin, as a rule, in the lower extremities, and extend upward to the trunk and face. The skin assumes a yellowish, waxy hue, and later becomes livid and perhaps mottled. It is extremely tense, does not pit on pressure, and imparts stiffness to the motions of the joints and the play of the muscles of the face. Sucking and swallowing may be prevented. The infant usually dies within a few days, but exceptionally may survive the disease. Dr. Lotta Meyers2 reported a mild case in a female infant, without the usual subnormal temperature, death occurring on the twenty- fifth day. Prognosis.—The disease is frequently, but not invariably, fatal. Diagnosis.—Scleroderma and scleredema, the only conditions re- sembling sclerema, may be distinguished by the fact that the first has not been noted before the second year (Stelwagon), while scleredema is seldom generalized or accompanied by extreme wasting, and does not deprive the skin of its color or elasticity under pressure. Treatment.—The only management of possible value consists in the maintenance of nutrition and bodily heat. In suitable cases the incubator may be used. ASPHYXIA NEONATORUM Asphyxia neonatorum is a condition of the newborn of grave menace requiring the most active and intelligent treatment. Etiology.—The asphyxia is due to a subaeration of the blood of the fetus or infant. This subaeration may be caused by anything which tends to retard the interchange of carbon dioxid and oxygen in the fetal circulation, and may take place before or during labor. As a result of the interference of the placental interchange of gases, the products of metabolism in the fetus stimulate the inactive respiratory center. This at first causes respiratory efforts, with the aspiration of more or less air, meconium, or amniotic fluid, according to the infant’s position in the parturient tract, and later, if the subaeration is not relieved by the quick extraction of the child, allowing access of air for the expansion of the lungs, depression of the respiratory center is the result. The causes operating antepartum include any conditions which inter- fere with the oxidation of the mother’s blood, such as cardiac or res- piratory disease in the mother, hemorrhage, or eclampsia; anything which causes a premature separation of the placenta, such as placenta prsevia or accidental hemorrhage; and anything which causes pressure upon the cord or the child, as the premature rupture of the membranes, 1 Jour. Cutaneous Diseases, October, 1912. 2 Ibid., 1909. ASPHYXIA NEONATOKUM 169 maternal convulsions, or tetanic contractions of the uterus. During labor, likewise, pressure upon the corcl from prolapse or malposition, pressure upon the head, with or without meningeal hemorrhage, or sepa- ration of the placenta before the delivery of the head, as in “vaginal birth,” may cause asphyxia. Prematurity and congenital disability or defects, such as atresia of the pulmonary artery, may be causative factors in- herent in the child. Pathology.—The pathologic changes are due to the venous engorge- ment and the aspiration of fluids. The right heart is distended with fluid blood or soft clots; the vena cava, the large thoracic veins, the sinuses of the dura, and the hepatic vessels are also distended. The pulmonary vessels may be distended or not, according to the extent and degree of respiratory efforts made. As a result of aspiration the trachea and bronchi may be quite filled with mucus, meconium, blood, and amniotic fluid. The lungs may show areas of atelectasis, or may be partially aerated and intensely engorged. The liver is dark bluish in color. There may be punctate hemorrhages in various parts of the body. Symptomatology.—It has been customary to divide the symptoms of asphyxia neonatorum into two groups, according to the color of the child and the state of the musculature—asphyxia livida and asphyxia pallida. They are essentially the same condition, asphyxia pallida being the terminal stage of asphyxia livida, and a case of asphyxia pallida (if recovery takes place) passing through the stage of asphyxia livida. Asphyxia Livida.—The child who is in the condition of asphyxia livida presents a characteristic appearance: the skin is blue or livid, the mucous membranes are dusky, the sclerotics are congested. The pupils are equal and react, and the position of the eyes is normal. The respiratory efforts are infrequent and gasping. The heart action is rapid and tumultuous, and the heart sounds are loud. The umbilical vessels are engorged and pulsate forcibly. The muscles are everywhere tense; the reflexes are active; the cutaneous sensibility is preserved, and the skin is warm. The anal sphincter functionates. The condition is a sthenic one, and analogous to the convulsive stage of ordinary asphyxia. A child in this form of asphyxia may recover by the respirations becoming more frequent, the color changing to normal hue, the over- acting heart quieting down, and a normal condition appearing; or the condition may pass by gradual stages into the other form—asphyxia pallida. The degree of asphyxia in the beginning may be midway between the two types. Asphyxia Pallida.—The child with asphyxia pallida is limp and pale. The entire musculature is relaxed, the lower jaw and head hang down, and the limbs drop. Respiratory efforts are absent altogether or so slight as to escape detection. The cord is flabby, the pulsation is inappreciable, or can be hardly felt, and the cord, when cut, bleeds very little. The heart sounds are usually faintly heard and may be slow or rapid. The sphincter ani is relaxed and allows the passage of meco- nium. The subcutaneous sensibility and reflexes are abolished. The tem- perature is lowered 1 to 3 degrees. In this form spontaneous recovery almost never takes place. 170 THE PRACTICE OF PEDIATRICS Diagnosis.—The diagnosis of asphyxia neonatorum may be made intrapartum by detecting the slowing of a previously well-acting fetal heart, the passage of meconium in the liquor amnii, the trembling of the head in a breech extraction, and the so-called vaginal cry. Postpartum, the condition is recognized by the symptoms as detailed. Asphyxia neonatorum must occasionally be differentiated from meningeal hemor- rhage, which is likewise caused by prolonged labor and which often occurs with asphyxia. When the hemorrhage is large, it can be readily recog- nized by the bulging, tense fontanel and by the existence of coma and possibly paralysis. Hemorrhage may affect the respiratory center, in which event the two conditions are really one. Prognosis.—The prognosis without treatment is always bad. In cases of asphyxia pallida spontaneous recovery is rare, and even with the most active treatment many do not survive. After apparent recov- ery death may yet occur from weakness or injuries incidental to the initial asphyxia. Idiocy and feeble-mindedness may often be due to the same cause. Prophylaxis.—In the treatment of asphyxia prevention belongs to the province of the obstetrician. Everything shoidd be done to avoid any of the maternal causative factors, and in the conduct of labor itself the aim of the physician should be to deliver the child as quickly as is compatible with safety, not hesitating to apply low or medium forceps in preference to a long and tedious second stage. Treatment.—The active treatment is directed toward maintenance of body heat and stimulation of respiration. The child, as soon as born, should be wrapped up, and if asphyxia exists, active treatment should immediately be instituted. The mouth and throat should be wiped free of the mucus, which will almost invariably be found, by means of the index-finger well wrapped with absorbent cotton or sterile gauze. It may be necessary to suck out the secretions by means of a catheter and a glass tube with a bulb on it to prevent the secretions from the mouth of the physician or nurse getting into the child’s pharynx. This will be especially necessary when, as the result of respiratory efforts during the passage of the head through the pelvis, much amniotic fluid, mucus, etc., may have been aspirated. It is not advisable, however, to attempt much instrumentation of the larynx, but to rely on Schultze’s method for bringing out aspirated secretions. The respiratory center must be stimulated. This may be attempted, depending upon the severity of the asphyxia, by tickling the nares, by administering the fumes of ammonia, by spanking (“flagellating the buttocks,” Koplik), by the alternate use of hot (110° F.) and cold (60° F.) baths, the child being transferred rapidly from one to the other, always ending with the hot one, or by combining with these one of flu1 various methods of artificial respiration, of which the simplest is perhaps the mouth-to-mouth method. Sometimes bleeding of the cord will relieve the intense congestion of the right heart and large thoracic veins, and allow the heart to restore the circulation and relieve the respiratory center. The most commonly used methods of artificial respiration are those of Laborde, Dew, and Schultze. The Laborde method consists in making rhythmic traction on the ASPHYXIA NEONATORUM 171 tongue, from twelve to fourteen times a minute, which it is claimed ex- cites respiration. The Dew method consists in grasping the infant by the back of the neck with one hand and by the knees with the other. The upper and lower portions of the child are then approximated by a flexion of the thorax on the abdomen, and the reverse movement, extension, is next effected. Alternate flexion and extension are thus practised fifteen to twenty times a minute. Schultze’s method as described by him and quoted by Edgar1 is as fol- lows: “The child lying upon its back is grasped by the shoulders, the open hand having been slipped beneath the head. The last three fingers remain extended in contact with the back, while each index-finger is inserted into an axilla, the thumbs lying upon and in front of the shoulders. When the child thus held is allowed to hang suspended, its entire weight rests upon the two fingers in the armpits. It is now swung forward and upward, the operator’s hands going to the height of his own head; the pelvic end of the child rises above its head and falls slowly toward the operator by its own weight, flexion occurring in the lumbar region. The thumbs in front of the shoulders compress the chest, while the hyper- flexed lumbar vertebrae and pelvis compress the abdomen, and through it the thorax; finally, the last three fingers on each side compress the thorax laterally. As a result of this maneuver, when properly done, aspirated secretions flow abundantly from the mouth. The distended heart also feels the compression which forces the blood into the arteries. The child is now swung back into its original position and supported entirely by the fingers in the axilla. The compression of the thumbs and last three fingers is removed. The downward swing elevates the sternum and ribs, while gravitation and the traction of the intestines depress the diaphragm. It is often possible to hear the air rush into the infant’s glottis as it reaches the original position, although this can occur in a cadaver. The amplification of the thorax lowers the intracardiac pressure. The child should be swung up and down ten times for the space of a minute. The effects of the maneuver should be as follows: the heart beat increases in frequency, the cadaveric pallor of the skin becomes re- placed by a rosy hue, and the muscular tonus appears. The child is then placed in a warm bath and watched. If the inspirations are superficial, a momentary dip in cold water is indicated. If the heart action becomes poor, the child should be swung again. If prolonged swinging becomes necessary, the root of the tongue should be compressed forward in order to raise the epiglottis and permit the removal of secretions with the fingers. In premature children the thoracic walls are often too soft to benefit by the compression of the fingers. In these cases insufflation of air should be practised.” In the cases of asphyxia livida, where the reflexes and the cutaneous sensibility are abolished, all attention should be devoted to the general stimulation of the child. The cord should be cut at once; it will often not bleed at all. The air passages should be freed from accumulated secretions as before. The child should be put into a warm bath and artificial respiration attempted by the mouth-to-mouth method or La- 1 Edgar, Practice of Obstetrics, 5th ed., p. 791. 172 THE PRACTICE OF PEDIATRICS horde’s method. Rectal injection of 1 to 2 ounces of coffee infusion, or hypodermic injection of grain of strychnin, may be given and re- peated in half an hour. Signs of recovery in asphyxia pallida are a return of the cutaneous sensibility, a reappearance of the reflexes, an increase of the tonicity of the muscles, one or more respirations, or a gradually increasing cyan- osis and venous engorgement approximating the condition of asphyxia livida. Finally, a gradual change to normal hue, with restored respira- tion and relaxation, indicates recovery. A strict watch must be kept over the child for several days, for re- lapses are common. Oxygen must be at hand, and all apparatus ready for a resumption of the active treatment at any moment. DELAYED ASPHYXIA Asphyxia may occur after birth in a child who has had an unevent- ful delivery and who appears quite normal when born. Etiology.—This form of asphyxia is due to some cause interfering with the proper continuance of the respiratory function. Developmental anomalies, such as defects of the nervous system, the heart, the dia- phragm, the thoracic wralls, or the lungs, or the general weakness of pre- maturity, may be the cause. Compression of the trachea by enlarged thyroids, and possibly by thymus glands, has been reported. Syphilitic pneumonia or bilateral pleuritic effusions or an enlarged liver may be the etiologic factors. Symptoms.—The clinical symptoms correspond closely to those of ordinary asphyxia. The infant makes very feeble respiratory efforts or none at all; the heart beats with considerable strength, becoming weak as the asphyxia continues and approaches the stage of flaccidity. Prognosis.—The prognosis is dependent upon the severity of the asphyxia and the removability of the cause. Treatment.—Treatment is that of any form of asphyxia, and con- sists in stimulating respiration and circulation upon the removal of the cause. Asphyxia due to prematurity should be treated according to the methods advised for caring for premature babies (p. 164). ATELECTASIS Atelectasis may be present in the newborn who come into the world asphyxiated, and it is not infrequently seen when there has been a prolonged, difficult delivery. Atelectasis may be the result of weak- ness, pure and simple, and is not of unusual occurrence in the premature. For some reason there is a failure or inability to dilate the air vesicles. Sudden collapse may occur in marantic infants, the child dying in a few moments with cyanosis and orthopnea, the autopsy proving the diagnosis of atelectasis. The condition may be produced also through compression of the lung with exudation in pleurisy, or by the obstruction of a bron- chus with mucus. The most dangerous types are those which are present in the newborn and which occur in the weakly during early life. The warning symptoms are usually cyanosis and rapid superficial breathing, with or without convulsions. SEPSIS IN THE NEWBORN 173 Treatment.—The management of atelectasis, both in the newborn, who come into the world asphyxiated because of prolonged difficult delivery, and in those in whom the condition is the result of weakness, consists in making the child cry lustily. If auscultation over the lower lobes posteriorly does not show free vesicular breathing, the child should be made to cry every day, either by spanking or by plunging him first into water at 110° F. and again into cold water at 60° F., our object being to induce vigorous crying and thus dilate the air vesicles. A recent patient made satisfactory improvement by receiving oxygen inhalations for one minute out of every fifteen, with stimulation of various kinds to induce crying. Atelectasis from obstruction of a bronchus or from com- pression is usually readily relieved when the source of the trouble is re- moved. In out-patient work we occasionally see marantic young infants in whom there is an involvement of a considerable area of one of the lower lobes posteriorly without any sign whatever of discomfort. The process of resolution in these cases progresses from the periphery toward the center and is very slow. The condition is probably of much more frequent occurrence than is generally supposed, if we are to judge from the autopsy findings in cases of young infants, particularly in institutions. The newborn infant is peculiarly susceptible to infections, partic- ularly with pyogenic bacteria. During this early period of life the normal bodily defenses are weakened. Phagocytosis, which is the great protector of the adult, is of little service to the newborn, who display little resistance against any bacterial invasion. Etiology.—The cause of sepsis in the newborn is the entrance of some form of pathogenic bacteria into the body. These bacteria are usually of the streptococcus or the staphylococcus groups. The pneu- mococcus, the colon bacillus, and Bacillus pyocyaneus may also cause the condition. These bacteria have been shown to exist even in normal breast milk, and they lurk in the air of hospital wards and dwellings. The lochia and amniotic fluid of the mother have been shown to contain them. The newborn infant is thus surrounded on all sides by bacteria ready to gain admission to his body. The severity of a given case of sepsis is proportionate to the degree of virulence of the bacteria at the time of the infection. Sources of Infection.—Infection may occur through the mouth, which is probably the most frequent port of entry, through the nose, the skin, the rectum, the conjunctivse, the digestive tract, the lungs, the ears, the urethra, the umbilicus, and, in girls, the vagina. Almost any portion of the body may be the seat of the infection. It is rare to find only one organ or structure affected. Usually two or more portions of the body are involved in the septic process. Parts Most Frequently Involved.—The following parts of the body are most frequently involved: Umbilicus.—The seat of this infection is usually about, or in the substance of, the stump of the umbilical cord. The skin and tissues about the umbilicus are red, indurated, and show the usual signs of septic SEPSIS IN THE NEWBORN 174 TIIE PRACTICE OF PEDIATRICS infiltration. The blood-vessels of the cord may be the seat of inflam- mation. Peritoneum.—Peritonitis may follow the extension of the septic process from the umbilical cord to the peritoneum, and under such conditions often results fatally. The peritonitis may be local or general. Joints.—The joint surfaces and membranes may be the seat of sup- puration, or osteomyelitis may occur. Sometimes the epiphysis only is involved, and in other cases the shaft of the bone is affected. Skin.—Single or multiple abscesses of the skin and underlying cellular structures are also not infrequent. Lungs.—Pneumonia, usually of the bronchial variety, may develop as a septic process, with only vague symptoms, such as rapid respira- tion and cyanosis, accompanying the fever. Intestines.—Diarrhea accompanies nearly all forms of sepsis in the newborn. Vomiting may occur. Brain.—The meninges are rarely attacked by the septic process, and when they are involved, indefinite symptoms of meningitis are the result. Heart.—Septic pericarditis may occur, but is extremely rare. Septic endocarditis is more common. Gonorrheal sepsis is discussed separately (pp. 178, 518 and 794). Prophylaxis.—This is of the greatest importance in guarding against sepsis. The obstetrician’s hands and those of the nurse should be just as sterile when handling the newborn infant as they are in caring for the mother. Asepsis should be stringently observed in ligating the cord. The mother’s breasts and nipples should be cleansed with boric acid before and after each nursing. Prognosis.—Even in its mildest form, septic infection of the new- born is very serious. When structures such as the peritoneum, brain, pericardium, or lungs are involved, the disease is invariably fatal. The red cells are decreased by disintegration, while the leukocytes are increased. Treatment.—The management resolves itself into relieving the system of the infection, which is possible when its seat is in the skin. When there is multiple abscess formation, incision should be made and fol- lowed by a wet dressing of a saturated solution of boric acid, or, if the area is not too large, a 1 : 5000 solution of bichlorid. If the site of the infection is at the umbilicus, the suppurating surface should be thor- oughly cleansed and kept covered with a wet dressing of 1 : 5000 bi- chlorid, which should be changed at least every two hours. If there is erysipelas, an ointment composed of 30 per cent, ichthyol in vaselin affords one of the best dressings. This should be freshly applied every four hours. The septic infant, whether the infection is mild or severe, usually nurses very poorly. Often both breast and bottle are refused. When a sufficient amount of fluid is not taken, plain boiled water or sugar water, 5 per cent., or completely peptonized skimmed milk, may be given by gavage. If fluids are not given, the child is very apt to develop inanition fever, which, added to the infection, makes a serious condition more serious. From 2 to 4 ounces of a normal salt solution used lukewarm, UMBILICAL GRANULOMA 175 injected into the descending colon through a catheter, will often be re- tained, with beneficial residts. It should not be repeated oftener than once in six hours. Early transfusion in sepsis neonatorum deserves the place of a routine procedure. Medication other than small doses of alcohol—5 drops of brandy, well diluted, every hour, if necessary—has been without avail in our cases. The prognosis at best is very grave, although cases in which the vital organs are not involved occasionally recover. Illustrative Case.—An unusual instance of infection which ended in recovery was that of a child who had no fever, but lost rapidly in weight and experienced marked pros- tration. The skin took on a greenish hue, and we were at a loss to discover the cause of the illness. The infection was suspected, but no portal of entry could be found; neither could we find any localized process until the nurse discovered that the umbilicus and the surrounding skin were bathed in pus. The umbilicus had apparently healed without any indication of local trouble. Investigation showed, however, that the infection had entered at this site, and, extending along the vein or artery, had become pocketed and formed an abscess II inches deep. Enlarging the opening at the umbilicus and estab- lishing free drainage were followed by a gradual closure of the abscess cavity and re- covery. THE CARE OF THE STUMP OF THE UMBILICAL CORD Emphasis must be laid upon all procedures tending to diminish the incidence of sepsis. The management of granuloma, polypus, and localized eczema about the umbilicus will be referred to elsewhere. In order to secure a rapid and complete cicatrization after the cord falls it is essential that the parts be kept dry. Gratifying success has been obtained with a powder composed as follows: Pulveris acidi salicylici gr. x Pulveris acidi borici gr. xxv Pulveris amyli, Pulveris zinci oxidi aa 5ss UMBILICAL GRANULOMA A granuloma at the umbilicus consists of a reddish, secreting mass of granulations involving the umbilical stump. It may vary in size between that of the head of a pin and a pea. Granulomata usually occur in cases in which the care of the cord has been neglected. In out-patient work they are very frequently seen, and occur usually in children who have been delivered by midwives. The mother brings the child to the dispensary with the story that the navel will not heal. The granulations are very vascular and bleed readily. Treatment.—After thorough cleansing of the parts, one or more ap- plications of a 50 per cent, nitrate of silver solution, followed by the free use of an absorbent dusting-powder, soon produces a normal cica- trix. A powder of the following composition is recommended: lb Acidi salicylici gr. xv Acidi borici gr. xxv Pulveris zinci oxid,i Pulveris amyli aa 3j 176 THE PRACTICE OF PEDIATRICS The powder should be applied very freely at two-hour intervals during the day, or at least often enough to keep the wound dry. UMBILICAL POLYP An umbilical polyp is usually the result of an overgrowth or an out- growth of a negelected granuloma. The mass, which may vary in size from a flaxseed to a pea, is reddened, moist, and usually bathed in a viscid, mucopurulent secretion. There is often considerable excoria- tion of the skin about the umbilical opening. Sometimes the mass is so small that it is hidden by the overlapping folds of skin and its pres- ence would not be suspected but for the secretion which keeps the parts moist. The polyps are very vascular. Treatment.—Cutting the pedicle and applying nitrate of silver or carbolic acid is not a safe procedure. Severe hemorrhage has followed such treatment. About twenty-five years ago the senior author was obliged to sit for three hours by the side of a crying, wriggling child mak- ing pressure on the cut stump of an umbilical polyp after a colleague had cut the pedicle. In no other way coidd the hemorrhage be controlled. The best management in these cases is to ligate the pedicle and allow the polyp to wither and drop off. The powder referred to under the head of Granuloma should be applied after the ligature is fixed, and reap- plied frequently before and after the polyp has dropped off, until the wound is cicatrized and dry. CONGENITAL UMBILICAL HERNIA This subject is discussed under the general topic of Hernia (p. 283). MASTITIS IN THE NEWBORN Inflammation of the breasts in the newborn, both in the male and in the female, is seen with considerable frequency in hospital prac- tice. The mammary glands may be acutely tender and swollen to several times their normal size. These glands in young infants shoidd not be pressed or manipulated in any way more than is required for cleanli- ness. Not a few out-patient cases of mastitis have been due to the at- tempts of a midwife to express the milk from the breasts. The cases are explained by the fact that the opening of the nipple is large and the gland readily becomes infected from unwashed hands or unclean wearing apparel. Treatment.—The cases have usually responded well to the appli- cation of ichthyol—25 per cent, in oxid of zinc, U. S. P. The ointment is spread generously upon old linen which has been boiled and dried, and is then gently bound upon the inflamed gland. Over this is placed oiled silk to protect the clothing, and over all a gauze bandage is ap- plied with very light pressure. The dressing should be changed and fresh ointment applied every six hours. Wet dressings in the manage- ment of this condition in infants are not advised. In 5 cases the mas- titis was beyond control when first seen, and suppuration of the gland— mammary abscess—followed, requiring incision and drainage, with loss of the gland substance. TETANUS NEONATORUM 177 MAMMARY ABSCESS IN INFANTS Mammary abscess is the result of mastitis which has failed to undergo resolution. It occurs as frequently in males as in females. All the senior author’s cases but 2 were seen in institutions or in out-patient work. In 5 the abscess developed under his own observation. In the case of a female child at the New York Infant Asylum both glands were en- tirely destroyed. Treatment.—As soon as pus is discovered the abscess should be in- cised and drained, with a view to saving as much of the gland as possible. Of course, this advice applies particularly to a female patient. Wet dressings are not applicable in cases of young infants when the parts covering the thorax or abdomen are involved. It is good custom to pro- tect the skin from infection by the use of a 25 per cent, boric acid oint- ment in cold cream as a base. This should be applied on old linen about the abscess opening. The dressing should be changed three times daily. Tetanus is an acute infectious disease caused by the tetanus bacil- lus, an organism having its natural habitat in garden soil or dung heaps. Its point of entrance into the human body may be a lacerated wound, a mere abrasion, or, as is the case in tetanus neonatorum, the umbilicus. The local reaction may be very slight or attended by suppuration. Tetanus is extremely rare in our hospitals and institutions for children because of the care exercised in treating the umbilical wound. Wherever gross uncleanliness prevails, tetanus neonatorum will be found. It is particularly prevalent among savage and half-civilized races. Specific Cause.—The tetanus bacillus is a slender, slightly mobile organism, positive to Gram’s stain, growing only anaerobically, and de- veloping a round spore characteristically placed at one end of the rod, giving it a nail or drumstick form. It was described by Nicolaier in 1885, and cultivated four years later by Kitasato. The bacilli remain localized at the seat of infection, whence their toxins are carried along the axis-cylinders of the motor nerves to the motor cells of the spinal cord, pons varolii, medulla oblongata, and, to a lesser degree, the brain cortex. The localized spasms characteristic of the disease are due to the action of the tetanus toxin on the ganglion cells. Incubation.—From the second to the ninth day is the usual period for the development of the disease, although it may appear as late as the fifth or sixth week. The period of incubation of the tetanus bacillus in man is probably of wide variation. The disease may appear immedi- ately after birth or be delayed for five or six weeks. Few cases, how- ever, develop after the third week of life. Pathology.—The lesions found at autopsy in infants dead of tetanus neonatorum are few and non-specific in character. Acute omphalitis is usually present. The thoracic and abdominal viscera do not show any abnormality. The meninges of the brain and spinal cord are con- gested, while small hemorrhages into the nerve substance are frequent. These are manifestly the result, and not the cause, of the tetanic spasms. TETANUS NEONATORUM 178 THE PRACTICE OF PEDIATRICS On microscopic examination degenerative changes in the nerve-cells of the gray matter of the spinal cord are noted, but these changes are in no way specific. Prognosis.—Few cases recover. Holt reported one recovery. The mortality is high. Those writers who have seen much of the disease place the mortality at 95 to 98 per cent. Symptoms.—The earliest symptom usually observed is difficulty in nursing. The child attempts to grasp the nipple and lets go suddenly and cries. Perhaps the infant will give a sudden start and cry as though in acute pain, which is doubtless the case. Examination of the patient will show well-marked trismus; the jaw is set; the jaw muscles are tense. Stiffening and relaxation of the muscles successively occur. As the case progresses the muscles of deglutition become involved, and swallowing is impossible. The lips are said to pucker in the position of whistling. The temporary relaxations become shorter; there is a tonic spasm, and, at the slightest irritation, such as the dropping of a pencil or a sud- den, awkward movement of an attendant, the muscle spasm increases until a marked permanent opisthotonos results. The temperature is usually high—104° to 106° F.; the pulse very rapid—180 to 200. Death is usually due to exhaustion. Spasm of the respiratory muscles is prob- ably a factor. Treatment.—The treatment consists in the use of antispasmodics— among which bromid and chloral are most frequently used. Large doses are necessary. In Holt’s recovery case 8 grains of sodium bromid were given every two hours. The patient is to be kept very quiet. Food and drugs are adminis- tered through a tube. Tetanus Antitoxin.—Tetanus antitoxic serum is made by inoculat- ing a horse with tetanus toxin formed by the growth in bouillon of the tetanus bacillus. Its prophylactic use has been of far greater value than its curative effect, and in every case of possible tetanus infection a dose of 1500 units of the antitoxin should be injected subcutaneously near the wound. Repetition of the dose after the expiration of a week gives ad- ditional security. In order to do good, after symptoms of tetanus have appeared, the antitoxin must be administered as early as possible. The New York City Board of Health advises giving the initial dose of 10,000 units in- travenously, and, if possible, also into the spinal canal and into the sheath of the nerve of the affected part. These energetic measures should be followed by subcutaneous doses of 5000 to 10,000 units every six to twelve hours for four days. In more severe cases, or in those in which symptoms have been present for several days before the treatment was begun, the initial dose should be doubled. It is also recommended that the wound be treated with a solution of iodin and that large amounts of water be given for its diuretic effect, since tetanus toxin is eliminated by the kidneys. OPHTHALMIA NEONATORUM—GONORRHEAL OPHTHALMIA One of the commonest forms of sepsis occurring in the newborn is acute purulent conjunctivitis. ICTERUS NEONATORUM 179 Etiology.—In almost all instances the infection is conveyed at par- turition from a pre-existing vaginitis of the mother. Two-thirds of the cases of ophthalmia neonatorum are produced from gonorrheal vaginitis; one-third from simple catarrhal vaginitis.1 In cases in which the gono- coccus is absent from the discharge the pneumococcus, Bacillus coli, and other organisms may be found. Infection may be conveyed indirectly after birth by dressings or towels or even by the fingers of the obstetric nurse. Symptoms.—The condition becomes evident between two and four days after birth; infection developing later is acquired postpartum. The conjunctiva becomes red and swollen and is bathed in a secretion at first serosanguineous, then seropurulent, and ultimately purulent. The swelling and chemosis diminish during the stage of profuse purulent discharge which lasts two to three weeks and then gives way to a chronic inflam- mation with thickening of the conjunctiva which ordinarily persists for several weeks longer. Exceptionally this final stage is shortened. In four-fifths of the cases the disease is bilateral. Complications.—Corneal infiltration with ulcer formation is frequent. Perforation of an ulcer may be followed by staphyloma and even pan- ophthalmitis. Prognosis.—Under early and efficient treatment the prognosis is fairly good, depending on the virulence of the infection and the degree of corneal involyement. Treatment.—Prophylaxis by the Crede method has become general and in advanced communities is almost universally compulsory. The method consists in immediate cleansing of the infant’s eyes at birth, followed by the instillation of a drop of 2 per cent, silver nitrate solution. “A 1 per cent, solution of silver nitrate may be substituted, but 25 per cent, argyrol or 10 per cent, protargol are not so reliable.”2 Treatment of the developed disease consists in the application of an eye shield to the unaffected eye (if one has escaped), and in the use of iced compresses and cool boric acid irrigations until tension and redness have abated. In the event of corneal involvement hot applications are to be substituted. During the later stages daily applications of 1 per cent, silver nitrate solution to the everted lids are recommended. It is a safe rule to treat all cases of purulent conjunctivitis in in- fancy as if they belonged to the gonorrheal type. Too great care cannot be taken by physicians and nurses in the handling of these cases to prevent spread of the discharge by contaminated articles, and a safe rule is for all engaged in caring for such patients to wear glasses as a protection from spurting pus droplets and contaminated fingers. The theories relating to icterus neonatorum are most ingenious, but as all, or most all, are based on speculation, they are, as a result, most unsatisfactory. In fact, only very recently has there been much ex- perimental work along this line. As Stadelmann stated years ago, “Without a liver, no icterus,” so ICTERUS NEONATORUM 1 May, Diseases of the Eye, 10th ed., p. 108. 2 Ibid., p. 109. 180 THE PRACTICE OF PEDIATRICS it is true today that theories excluding the liver as a participant are valueless. The forms of icterus in which biliary acids are demonstrated in the urine must be attributed to the resorption of bile in the liver. In icterus neonatorum the presence of biliary acids has been clearly demonstrated not only in the urine (Holberstein), but also in the peri- cardial fluid (Hofmeister). In view of these facts it is apparent that the liver must play the all-important part in the production of icterus because it is certain that the jaundice cannot be explained by hyperemia or cap- illary hemorrhage. The so-called hematogenous jaundice deserves more consideration in the light of recent experiments. Such explanations as that of Franck, assuming a plugging of the ductus choledochus by means of mucus and cast-off epithelium, have been disproved. Of no further moment is the theory of Birch-Hirschfeld, who assumed an edema of Glisson’s capsule; none of these assumptions has been verified by other observers. By anatomic examinations of the liver Bouchut’s hypothesis of a hepatitis, and Epstein’s theory of a catarrh of all ducts of the liver, have been demolished. To the hematogenic factor, which has been strongly supported by Hofmeier, Stadelmann, and others, one must give more than a passing thought. These authors assumed that, as a result of the countless destruc- tion of erythrocytes during the first days after birth, a polycholia resulted. This supposition of red-cell destruction has been refuted, the cause for the apparent destruction being attributed to increase in the blood-plasma. Heiman1 supported the blood destruction theory, stating that an actual destruction of erythrocytes does occur. Assuming this later observation to be correct, one can readily see how with this destruction there is libera- tion of hemoglobin, which is taken up by the liver and transformed into bile pigments. It is further apparent that when bile is thus produced in excess and is taken up rapidly by the liver in large amounts, the bile capillaries are overtaxed and the bile cannot be rapidly removed, but is reabsorbed into the blood, whereupon choluria develops. If this excessive production of hemoglobin increases over certain limits, the “threshold of the kidney” is reached and the hemoglobin is excreted through the kid- neys, thus producing a hemoglobinuria.2 The theory today, which, according to Finkelstein3 probably finds greatest acceptance, is that of Quincke. This author considers a patency of the ductus venosus to be the deciding factor; by a persistency of the lumen of this duct the bile passes directly from the meconium in the intestine to the portal vein, and, circumventing the liver, enters the infe- rior vena cava, thus producing the icterus. In the light of more recent research, however, this duct has been found open as late as the fourth week of life; thus if this anatomic fact be considered a criterion, we would not be led to believe that icterus was produced by the patency of the ductus venosus, for if such were the case, icterus would be a phenom- enon not of the first week, but of the first month of life. According to Hess’s observation with the duodenal catheter, bile is excreted into the intestine rarely during the first twelve hours of life, 1 Zeitschr. f. Geburtsh. u. Gynak., 1912. 2 Pearce, Austin, and Eisenberg, Jour. Exp. Med., 1912. 3 Lehrbuch d. Sauglingkrankh., 1905. CONGENITAL ABSENCE OF THE BILE-DUCTS 181 and is variable during the subsequent twenty-four hours, but in every one of his cases was profuse in icterus neonatorum. In many of his cases of marked jaundice the secretion was so profuse as to overflow into the stomach—a fact demonstrated by the introduction of the stomach-tube. Although Hess stated that the cause of this condition is not at present definitely proved, if one follows the principles of the physiology of the secretion of bile, one can assume, what seems to be probable, that the icterus is due to an increased amount of available hemoglobin; further, that some bile salts are taken up from the intestine, resulting in this disintegration of blood cells and a consequent increase of bile. Approach- ing the matter from another view, one can readily assume that the di- minutive excretory mechanism of the liver at this stage is unable to cope with this excess of bile which Hess has demonstrated, and that a con- gestion of the bile capillaries ensues, as is shown by histologic examina- tions, and icterus results. Symptoms.—Probably 75 per cent, of all newborn infants show more or less icterus a few days after birth. The degree of jaundice varies greatly. In comparatively a small proportion of the cases the conjunctiva becomes deeply involved. Infants showing marked jaundice may lose in weight as a result of this condition. The jaundice rarely persists longer than two weeks, and such a duration is seen only in the severe cases. In the majority of the cases the skin is clear in a week after the onset. The urine is usually free from bile pigment. The stools are normal throughout the period. Treatment is not required. CONGENITAL ABSENCE OF THE BILE-DUCTS This malformation is of very rare occurrence. The first symptom, a rapidly developing jaundice, appears not later than the third day after birth. The jaundice increases rapidly, and in a few days is intense. In a case seen at the fifth month the skin was of a deep, greenish-yellow color, the conjunctiva was deep yellow, and the mucous membranes of the lips and buccal cavity were involved in the discoloration. In all cases after the passage of the meconium the stools become clay colored and so remain. The urine is of a deep brown color. The liver is always enlarged. Death usually results from inanition before the third month. In one case the child died at the ninth month. In two cases the common duct was represented by a fibrous cord; in another there was an entire absence of the common duct. An abnormality of the bile-ducts should always be thought of in cases of prolonged icterus neonatorum. Holmes1 made an extensive review of the literature covering over 100 cases, with 89 diagrammatic representations of the different de- formities. These diagrams show a wide range of deformities. Diagnosis.—In icterus neonatorum of the familiar type bile is never absent from the stools, even though there is a marked degree of jaun- dice, and the skin begins to clear in the second week. A continuation of the jaundice without abatement after this time is suggestive of con- 1 Amer. Jour. Dis. Child., vol. xi, No. 6. 182 THE PRACTICE OF PEDIATRICS genital obstruction of the ducts, and an examination of the stools de- termines the condition. HEMORRHAGIC DISEASES OF THE NEWBORN In 1861 von Hecker and Buhl described a series of cases, under the title of “Acute Fett-Degeneration der Neugeborenen,” that presented a somewhat similar picture without evidence of either syphilis or navel sepsis. Since that time this condition has been commonly called Buhl's disease. In the original article it was noted that most of the children were born in asphyxia. These cases showed the typical symptoms of the disease, and at autopsy all the viscera showed multiple hemorrhages as large as pinheads or larger, together with fatty changes that may be extensive. The authors did not attempt to explain the etiology, but considered that the condition was not due to navel infection and that it was not a manifestation of hemophilia because the ratio of males to females is not maintained as in hemophilia. In conclusion they said: “It is hardly necessary to state that one here has to do with a disturbance of metabolism manifested over the whole body, in which the changes in single organs are only a partial expression of the whole disease. This disturbance is evidently inborn, acquired in the last days before birth.” In 1879 Winckel tried to establish an entity distinct from the so- called Buhl’s disease by describing a series of cases that manifested a slightly different clinical and pathologic picture. He considered this condition distinct from Buhl’s disease, chiefly because it seemed to be epidemic in character and because the hemorrhages were more and the fatty changes less prominent than in the disorder described by Buhl. Winckel recognized the similarity of this condition to that of intoxica- tion by phosphorus, arsenic, and potassium chlorate, and he ruled out, by careful histories and by chemical examination of the viscera, any possible participation of these drugs in the etiology of his cases. In more recent times the Germans, in particular, have come to re- gard as Buhl’s disease any condition affecting the newborn, that pro- duces a severe icterus and fatty infiltration without evidence of infec- tion; whereas any similar condition, of which the chief features are icterus and hemoglobinuria, has been looked upon as Winckel's disease. These two classifications, however, have failed to suffice for all the hemorrhagic icteric conditions of the newborn infant. Various other names have sprung into rather general use, and have served to complicate the nomenclature by adding terms based solely on clinical and morbid anatomic differences. Melcena neonatorum is a term that has been applied to conditions in which hemorrhage has occurred from the gastro-intestinal tract, with- out necessarily any clinical evidence of hemorrhage elsewhere. Since 1829, when Cruveilhier found ulcers in the stomach of an infant who presented evidence of true melena, many others have recorded the pres- ence of such lesions with the result that a gastric or intestinal ulcer is usually considered to be the source of the hemorrhage in these conditions. Syphilis.—These hemorrhagic conditions have frequently been found associated with congenital syphilis. There are hemorrhages, cyanosis, HEMORRHAGIC DISEASES OF THE NEWBORN 183 edema, icterus, etc., but in many cases evidence of syphilis is wanting. Cases of Buhl’s disease have been recorded by Furstenburg as occurring spontaneously even in the offspring of domestic animals, where pre- sumably the presence of syphilis may be safely excluded. Bacteria.—The role of bacteria has received the greatest considera- tion for the following reasons: 1. The close similarity between these conditions and the picture produced by navel sepsis. 2. The epidemicity of at least one group (Winckel’s). 3. The finding of organisms at autopsy. 4. The experimental production in animals of certain of these con- ditions by inoculation with bacteria. The belief is now almost universally held that many different bacteria may produce these diseases, because of the variety of micro-organisms that has been found at autopsy (staphylococci, streptococci, Gartner’s bacil- lus, Bacillus pyocyaneus, B. coli, and various other types). The inocula- tion of animals with many of these organisms has frequently been fol- lowed by the production of diseases similar to those in human beings. In certain cases, at autopsy, lesions indicative of an infectious process, as, for example, hyperplasia of intestinal lymphatic tissue, have been found, but, on the other hand, such findings are frequently absent, and it is very striking that in many cases there seems to be very insufficient evidence that infection has played an important role. In general one may conclude that there is strong evidence favoring the idea that many cases are caused by infections, and, on the contrary, insufficient evidence for assuming that all are due to infections. Mechanical Causes.—Mechanical factors, such as trauma, thrombosis, embolism (Landau), deserve only mention, as they have been found only very occasionally (Thomson). Heredity.—The possible importance of hereditary influences was considered by von Hecker and Buhl when they stated that the disease was evidently inborn, and acquired during the last few days of preg- nancy. The relation of heredity to true hemophilia requires no present mention. There are certain affections of the adult, at present of unknown eti- ology, which, if transmitted to the fetus, might cause their various syn- dromes in the newborn. Reference is made particularly to the closely related conditions of acute yellow atrophy, of eclampsia, and of certain septicemic conditions. Numerous observations are on record describing the pathologic changes in the offspring of eclamptic mothers, and it is particularly interesting that in general the abnormal features correspond closely with the icteric and hemorrhagic syndromes of the newborn. Each report summarizes the pathologic changes as thrombosis and parenchymatous degeneration, fatty degeneration or necrosis, espe- cially in the liver and kidneys, hemorrhages in the organs, and subphrenal, subpericardial, and subendocardial extravasations of blood. Chemical Agents.—Finally, intoxication by known chemical agents occasions symptoms and pathologic changes similar to the disease in question. Among this long list of agents may be mentioned phosphorus, arsenic, potassium chlorate, and chloroform. That there are many 184 THE PRACTICE OF PEDIATRICS features of these conditions that suggest a common general process has already been emphasized by Knopfelmacher. Metabolic Changes.—The symptoms and gross changes are suggestive of poisoning by the above-mentioned agents, but they also occur in con- ditions of obscure etiology, such as acute yellow atrophy, eclampsia, arid cyclic vomiting of children. All the chief features that characterize this latter group, including certain metabolic phenomena, such as ap- pearance of lactic acid and sugar in the urine, not to mention others, are known to occur also after respiration of rarefied air or after asphyxia from any cause, that is to say, from lack of oxygen. In phosphorus- poisoning there is a deficiency of available oxygen. Chloroform does not belong to this group, producing deficient oxidation of the tissues; but it would seem, a priori, that there was some evidence to suggest the existence of a causal relationship between chloroform used at labor and the occurrence of some of these various conditions of the newborn. Evarts Graham (Chicago) concluded, after a careful experimental study and review of the literature, of which the preceding paragraphs are a resume, that the conditions of the newborn characterized by a hemorrhagic tendency, icterus, and fatty changes, are probably all sjm- dromes which may occur as the result of a number of toxic agents. He produced experimentally the essential features of the disease group by the administration of chloroform to the point of asphyxia. Duke believed that the bleeding is due to a deficiency in the number of platelets in the blood, and thus absence of thrombin formation, which is essential in order to produce clotting. In some cases the coagulation time is normal, in others, abnormal. Gelston1 has reported a case of hemorrhage in a newborn male infant treated by whole blood injections in which it was possible to demonstrate at the time of the hemorrhage a practical lack of prothrombin, while within eight hours after the cessation of the hemorrhage prothrombin was present in normal quantities. The loss of prothrombin-antithrombin balance is considered to be a direct factor in the etiology of such diseases. Gelston concluded: “Several possibilities present themselves. There may be simply a stimulation to the production of prothrombin; the injection may supply enough prothrombin to cause cessation of the bleeding, although not fully re-establishing the balance, or it may actually re-establish the bal- ance. The latter seems hardly logical, considering the small amounts of whole blood necessary. It is more probable that a combination of the first two possibilities is involved, with a stimulation to the produc- tion of prothrombin and the addition of a sufficient quantity in itself to bring the constituents just within the margin compatible with ap- proximately normal function.” Rodda2 found that the incidence of true hemorrhage neonatorum, which is accompanied by delayed coagulation and prolonged bleeding time, conformed closely to the prolonged coagulation and bleeding time observed for normal infants between the first and fifth days of life. 1 C. F. Gelston, Etiology of Hemorrhagic Diseases in the Newborn, Amer. Jour. Dis. Child., vol. xxii, p. 351. 2 Jour. Amer. Med. Assoc., August 14, 1920. HEMORRHAGIC DISEASES OF THE NEWBORN 185 Cerebral hemorrhage was found in over 50 per cent, of all infants who died intrapartum or during the first days of life. A considerable number of these cases have come under our observa- tion. Repeatedly hemorrhages from the newborn have been observed to occur in the internal organs and from various portions of the body. A colored infant at the New York Nursery and Child’s Hospital bled to death in the pericranial tissues without a sign of hemorrhage else- where. At this institution there was at the same time during the senior author’s service a small epidemic of fatal hemorrhages in the newborn. The colored child referred to was the only one in which the hemorrhages were not multiple. Some cases were due to proved sepsis; in others there was no demonstrable lesion of the blood or vascular apparatus. In one infant the hemorrhages began on the third day subcutaneously on the dorsum of the foot and rapidly extended until the child bled to death in her own tissue. At this time we were not aware of the usefulness of human blood in these cases. In just such cases the results from human blood treatment referred to below are most promising. Treatment.—The use of styptics and astringents for controlling the hemorrhage is useless. The only local measure that has assisted in any way has been the application of pressure to the bleeding parts, and this is not possible in many situations. Adrenalin, locally or by internal administration, has not been of any appreciable service. Illustrative Case.—One of the most important contributions to the literature of hemorrhage in the newborn was presented in the Medical Record of May 30, 1909, by Dr. Samuel W. Lambert, of New York City. In his case a direct transfusion of blood from the father to the child was successful in stopping the hemorrhage when the case was almost hopeless. The only general treatment worth considering is the use of human blood, administered by transfusion or injected intramuscularly. During the past few years many cases of hemorrhage in the new- born have been treated by the use of human whole blood injections. The blood is readily drawn from the basilic vein of the donor and injected into the buttocks of the patient. This is the most rapid method. No tests are required for hemolysis and agglutination. One ounce of blood was used in each of 3 of the writer’s cases, completely controlling the hem- orrhage. When subcutaneous injections of blood prove ineffective immediate transfusion is indicated. Typing of the blood of both the infant and the donor should be done when possible in all transfusion cases. VII. DISEASES OF THE MOUTH AND ESOPHAGUS The term stomatitis is applied to an inflammation of the mucous membrane of the mouth. Three types are usually described by pediatric authors—the catarrhal, the aphthous, and the ulcerative. A specific type in which throat symptoms are usually pronounced, known as Vincent’s angina, is described on p. 319. There are many cases of catarrhal stomatitis which, under treat- ment, go no further; other cases, with or without treatment, go on to the development of aphthae, or an ulcerative condition. Both conditions may be combined. Many cases, when they appear for treatment, have the so-called aphthous spots already developed, but the condition des- cribed as “catarrhal stomatitis” also is present. Other cases when they come to us show marked ulceration, but never without catarrhal symp- toms. Bacteriology.—Catarrhal, aphthous, and ulcerative stomatitis have no established specific bacteriologic etiology. Etiology.—The cause of the disease is unquestionably an infection, and there is no doubt that it is contagious. As to the nature of the in- fection positively nothing is known. The combined action of several varieties of micro-organisms is the most plausible explanation. Stomatitis has been observed to go through an entire family of several children. Authors are prone to attribute the trouble primarily to mechanical irri- tation, such as careless manipulation during the mouth toilet; but the majority of children when they applied for treatment had never been accustomed to mouth toilets of any kind. The giving of overheated food is supposed by some to be a causative agent. If this were the case, 75 per cent, of the infants among the poorer classes would never be free from the disease. The food of bottle-fed children unless carefully watched is almost invariably given too hot. The disease, however, is not limited to dispensary patients. We have seen many cases among the well-to-do. Where gross uncleanliness is the family habit, the number of cases of sto- matitis will, for obvious reasons, be greater; there are more bacteria to carry infection. Children wThose mouths are carefully cleaned after each feeding do not develop stomatitis. To teach that a child’s mouth should not be washed because an indifferent doctor may fail to instruct the mother or nurse as to how it should be done is rank heresy. When errors of the mother or nurse occur in performing the various offices for the child, it is our observation that, nine times out of ten, the fault is due to lack of instruction by the physician. The mouth may be very effectually cleansed without injuring the mucous membrane in the slightest degree. Symptoms.—The first symptom of a stomatitis is a superficial ca- tarrhal inflammation of the mucous membrane of the mouth characterized by redness and injection of the gums. If “aphthae” develop, small gray- ish plaques appear on the mucous surface of any portion of the buccal STOMATITIS 186 STOMATITIS 187 cavity. In mild cases there may be but three or four areas. In a case of moderate severity the mucous membrane of the gums, the hard and soft palate, and the inner side of the cheek will be studded with ulcerated, grayish-white areas, varying in size from a pinhead to a split pea. Oc- casionally the areas coalesce, forming larger plaques of a serpiginous type. Ulceration, which ordinarily does not appear until after the catarrhal condition has been present for at least three or four days, will first be noticed as a faint yellow line at the margin of the gum where it joins the teeth. This is the commencement of what Virchow describes as “necrobiosis.” Ulceration never occurs unless teeth are present. We have never known a case to go on to ulceration in a baby fed entirely at the breast. Whether the case remains simply catarrhal, or whether aphthae or ulceration, or both result, certain symptoms are common to all. There is a marked increase in the flow of saliva, which in some cases may be said to stream from the mouth, running down over the chin and soiling the clothes. On account of its acid properties it causes irritation of the skin and even eczema. The mouth is hot and painful. Fever is present in a slight degree both when the condition is simply catarrhal and when aphthse are present. There is but little prostration and the child appears but slightly indisposed. In cases which go on to ulceration the fever may be very high, frequently 104° F. or over. In one case it reached 107° F., although no cause except the ulcerative sto- matitis could be found for the fever. Under properly directed treat- ment this child recovered in a few days. On account of the pain occasioned by drawing on the nipple nutri- tion may be considerably interfered with. The child takes the breast or bottle greedily, draws a few times, stops, and begins to cry. If he is urged to try again, the behavior is repeated. The pain appears to be particularly severe when aphthae are present. The advent of ulcera- tion will be indicated by a change in the breath, which becomes dis- gustingly foul. The gums are thick, spongy, and bleed easily, and in some cases overlap the teeth very early in the ulcerative stage. If a case has been neglected or improperly treated, which is the history of not a few dispensary patients, the ulceration is often so extensive that the teeth become loose as a result of the destruction of the gum, and their removal is necessary. Strong, vigorous children seem as susceptible to the disease as are the rachitic, the badly fed, or the generally delicate. Prognosis.—The prognosis is good. All cases recover if seen early and if properly treated. Loss of teeth may result in those seen when the process is well advanced. Treatment.—Mouth Washing.—When the stomatitis is catarrhal or aphthous, preventive treatment—the washing of the mouth after each feeding with a saturated solution of boric acid in boiled water—is also curative. A baby’s mouth should be washed as follows: The child is placed on the side or stomach. The index-finger of the mother or nurse thoroughly wrapped in absorbent cotton is then dipped into the solu- tion, and without expressing the fluid, is placed in the child’s mouth. By gentle pressure upon the gums and cheeks a sufficient amount of the fluid is then expressed to run out of the mouth and effectively cleanse it. 188 THE PRACTICE OF PEDIATRICS The washing is assisted by the opposition offered by the child to the manipulation of the tongue, cheeks, and jaws. Drugs.—Internal medication is of no value except indirectly. If there is a disordered digestive state, it should receive attention by diet and saline laxatives. Calomel should not be given. Whether the condition is catar- rhal or aphthous, it is practically never necessary to use other means than the free mouth washing. Astringents and caustics have never been necessary. The cases usually terminate in recovery in from four to seven days under strict attention to cleanliness as regards the feeding apparatus or the mother’s nipple, together with the free use of the boric acid solution as a mouth wash. Feeding.—The food problem is difficult to deal with, particularly in the case of nurslings, on account of the pain caused by drawing on the nipple, the child refusing absolutely to nurse. In some cases it may be necessary to draw the milk with a breast-pump, and for a day or two feed the baby with a spoon. With the bottle fed spoon feeding may also be resorted to. The child will take the nourishment much better if it is given cool. Small pieces of ice and teaspoonful doses of cold water are taken eagerly. Treatment After Ulceration.—With the development of ulceration a change in the management is necessary, both as regards a mouth wash and the necessity for internal medication. Among the local measures hydrogen peroxid as a mouth wash, 1 part of a 3 per cent, solution in 2 parts of water, used after each feeding, has given the best results. Such means, however, are rarely necessary if the case is seen early. Except in cases that show a considerable destruction of tissue no other means to secure cleanliness than the boric acid solution is required. Chlorate of Potash.—In the internal administration of chlorate of potash we have what is practically a specific in this disease. Its ad- ministration should be commenced as soon as the condition is recog- nized. One may prescribe the drug conveniently in syrup of raspberry, using 1 part of syrup to 2 parts of water. For a child under eighteen months of age one may order 2 grains at intervals of two or three hours —not more than 10 grains in twenty-four hours; for a child from eighteen months to three years of age 2 or 3 grains at the same intervals, not more than 15 grains in twenty-four hours. With the above dosage it will be necessary, in the average case to continue the drug from three to five days. Very often, after the improvement is well marked, we reduce the dose one-half and continue it for three or four days longer. Dangers of Chlorate of Potash.-—Much has been written concerning the danger of the internal use of chlorate of potash in children, particu- larly in relation to its effects upon the kidneys. If the use of the drug in suitable doses were of special danger in this respect, the free use of the chlorate of potash and iron mixture, so extensively prescribed in diphtheria in the pre-antitoxin period, would have been universally condemned. We have never seen any unpleasant effects from chlorate of potash given in doses of 10 to 20 grains daily, and we have used it in many hundreds of cases of acute inflammatory conditions of the throat and mouth. sprue (thrush; mycotic stomatitis) 189 SPRUE (THRUSH- MYCOTIC STOMATITIS) The disease makes its appearance in the form of small white masses of about the size of a pinhead. The tongue and the inner sides of the cheeks are favorite sites for the growth, although in severe cases the entire buccal cavity may be studded, as though finely curdled milk had been scattered over the surface, and the lesions may extend into the stomach. The growth is firmly adherent, and its forcible removal pro- duces slight bleeding. Etiology.—Sprue is invariably associated with uncleanliness, and occurs, as a rule, in weakly and marasmic nurslings and in the bottle fed—more frequently in the latter. The disease is rarely seen after the sixth month. Thrush, soor, or mycotic stomatitis is due to Oidium albicans, an organism which stands between the yeasts and the fungi. The threads of the mycelium end in egg-shaped conidia which bud and form new hyphse. Spores are formed only under favorable cultural conditions. Preparations made from the white patches on the buccal mucosa show both mycelia and yeast-like conidia. Symptoms.—An infant with this disease gives evidence of much pain and discomfort while nursing or while feeding from the bottle. Active gastro-enteric disturbances, such as vomiting and diarrhea, may be as- sociated with sprue, but such association is not the rule. Time and again one sees cases in which there are absolutely no other signs of the disease than the characteristic mouth lesions and the patient’s refusal of food. The average case may easily be cured in a week if treatment is carefully carried out. Sprue is not contagious, and if the means of prophylaxis, which will be suggested, are used as a part of the daily routine the dis- ease will never appear. Treatment.—If the patient is breast fed, the mother’s nipples must be washed with a saturated solution of boric acid and moistened with alcohol, diluted one-half, which is allowed to evaporate before each nursing. If the infant is bottle fed, both nipple and bottle should be boiled after each nursing, and the nipples turned inside out and scrubbed with borax water—1 ounce of borax to 1 pint of water. In either case the mouth should be washed with a saturated solution of boric acid after each feeding. For this purpose a generous amount of absorbent cotton loosely wrapped around the clean index-finger of the mother or nurse is placed in the cold solution, and then, without expression of the water, introduced by the finger into the child’s mouth. In the care of fully developed sprue, the application should be brought gently into contact with the diseased parts, first on one side and then on the other, and finally pressed over the tongue and under the tongue. It is well to have the child rest on the side or abdomen so that the fluid which is pressed out by the manipulation of the cotton against the cheek and jaws can readily escape from the mouth. The washing, which really amounts to an irri- gation, can be done in a few seconds, without the slightest danger of abrading the epithelium. In obstinate cases this treatment may be supplemented by penciling once a day with 1 per cent, solution of formalin. Internal medication is of no value except as a means of correcting 190 THE PRACTICE OF PEDIATRICS any intestinal derangement that may exist, with a view to improving the general condition. If the bottle or breast is refused, spoon feeding, for a few days, may be found necessary, and in any event will hasten the cure. If the child is nursed, the mother’s milk may be drawn with a breast-pump (see p. 54) or pressed out with the fingers and then fed by the spoon. The domestic remedy, honey and borax, should not be used in treating any of the inflammatory diseases of the mouth in children. Etiology.—No single micro-organism has been proved to be the cause of noma. Spirilla and fusiform bacilli have been found (Weaver and Tun- nicliff) not only in the necrotic tissue, but in the surrounding healthy parts. Whether these organisms represent the primary cause of the lesion or only secondary invaders is not known. In other instances Bacillus diphtherise has alone been found. The nature of the lesion points to the action of a specific infection. Measles and diphtheria are at times precursors of noma. Symptoms.—The site of the disease is usually the inner side of one or both cheeks. The gangrenous process usually begins as a small, in- flamed, infiltrated area in the mucous membrane opposite the teeth. Localized destruction of tissue follows, and. this process extends with great rapidity until the tissue sloughs away in masses. The parts for some distance around the ulcer become hard, infiltrated, and discolored, presenting an inflamed, edematous look. After two or three days a dis- colored, ecchymosis-like area may be noticed on the outer side of the cheek, corresponding in location to the gangrenous portion within. At this point the ulcer soon perforates. The destruction of tissue continues quite symmetrically around the ulcer until the whole cheek is destroyed. The process not infrequently involves the bony structure, causing necrosis of the jaw, with loosening and falling out of the teeth. A symptom which will never fail and can never be forgotten by one who has seen even one of these cases is the almost unbearable stench which emanates from the patient. When the hands or the fingers of the physician or nurse come in contact with the gangrenous slough, it is almost impossible to remove or neutralize the disgusting odor. The disease usually occurs in weakly, marantic children, who die, ordinarily, from exhaustion and sepsis within ten days or two weeks from the onset of the disease. Hemorrhage is rarely a complication. The disease is usually fatal, even under the best management. Treatment.—The treatment pursued has consisted in the use of free cauterization with nitric acid, chemically pure, and the application of disinfectant wet dressings of biehlorid 1 :2000, saturated solution of boric acid, or equal parts of alcohol and water. The dilute alcohol is apparently more effective in staying the progress of the disease than is either the biehlorid or the boric acid solution. On account of its rapid evaporation the alcohol should be applied on two or three layers of lint and covered with rubber tissue. Even then frequent renewals are required. Hydrogen dioxid may be used to cleanse the ulcer both before and after perforation. CANCRUM ORIS (NOMA) GEOGRAPHIC TONGUE 191 FISSURES OF THE LIPS Deep cracks and fissures in the lips are of quite frequent occurrence among children. Usually the lower lip is involved, and in many of the cases there is but one deep fissure and that at about the middle of the lower lip. Marasmic, ill-conditioned children are the most frequent sufferers. The fissures bleed easily and occasion considerable pain during nursing. As a result less food is taken than the child requires. Treatment.—If the fissure is deep, a 50 per cent, solution of nitrate of silver should be applied at the commencement of the treatment. This is to be followed by frequent applications—three or four times daily —of a 25 per cent, solution of ichthyol. Healing is usually prompt, requiring but a few days. If the mucous membrane of the lip generally is dry and fissured, as in cases of prolonged illness with fever, the frequent use of a 5 per cent, boric acid ointment, made with cold cream as a base, will be of material assistance in controlling the condition. ULCERATIONS AND FISSURES AT THE ANGLE OF THE MOUTH Ulcerations and fissures at the angle of the mouth are by no means uncommon in delicate and marasmic infants. While ulceration in this location is one of the manifestations of congenital syphilis, such ulcers are not necessarily syphilitic. The condition, however, is of sufficient importance to require treatment, because the affection is so painful as to prevent the taking of adequate nourishment. Painting the fissure with a 25 per cent, solution of ichthyol every three hours during the day will insure prompt healing. GEOGRAPHIC TONGUE The condition known as a “geographic tongue” consists of distinct, smooth, reddish patches on the tongue’s surface, surrounded by a light grayish, narrow, raised border. The smooth surfaces comprising the involved areas are devoid of epithelium; the borders are composed of hypertrophied papillae which take on a grayish color, making a distinct framework for the reddish areas, which are almost always crescentic in shape. This peculiar marking has given rise to the term “ringwTorm of the tongue.” Geographic tongue is seen most frequently in children under three years of age, and occurs as often among the strong and vig- orous as among the delicate and weakly. The condition is usually dis- covered by the mother, who, with much agitation, brings the child to the physician. It does not appear to be due to and is usually not associated with any disturbance of the gastro-enteric tract. That portion of the tongue which is not involved appears perfectly normal. Treatment of geographic tongue is unnecessary, as the condition causes no symptoms and apparently is independent of any disease. It is a good custom to assure mothers that the condition is of no conse- quence, for it usually disappears in a few months. One case was ob- served to last for a year. 192 THE PRACTICE OF PEDIATRICS DIFFICULT DENTITION It is claimed that the eruption of the teeth is a physiologic process, and as such is not productive of harm. In normal, well babies this is generally the case. There may be a slight fever and restlessness, with loss of appetite, associated with the eruption of a tooth, but the disorder is usually very temporary in character. In delicate children, particularly in those who teethe late, as in the rachitic, when several teeth are cut at one time, not a little inconvenience may be caused by dentition. Even these patients, however, rarely have grave digestive disorders. In a large experience with teething infants we have known barely one in whose case convulsions were apparently directly dependent upon denti- tion. Such an exceptional patient was a rachitic, institution child who cut his first tooth at the ninth month, and with each of the three succeed- ing teeth, which were cut during the next three months, developed con- vulsions without any other signs of illness. Temporary digestive disorders are of very frequent occurrence in this type of child during an active dentition. The child may be restless and irritable and perhaps have fever of a degree or two. His digestive capac- ity is lessened, and if the usual diet is continued, fermentative diarrhea results, which may be, and often is, the starting-point of grave intestinal disease. When it is apparent that the child’s generally good natured, daily habit of life is being unfavorably influenced by dentition, the food should temporarily be reduced, particularly if the weather is hot. Breast babies may be given water before each nursing so as to re- duce the capacity for milk. For the bottle fed 2 or 3 ounces of the food mixture may be removed from each bottle, the amount being replaced with boiled water. That cough and respiratory and skin diseases are immediate results of dentition is without foundation. During active dentition, when the gums are distended and swollen from pressure, relief will often be fur- nished promptly by rubbing through the prominent points of the tooth with a clean towel over the index-finger. Lancing alone may be per- formed, but unless the tooth is well advanced it is quite possible that the gums will reunite over the tooth, forming a cicatrix which will make the eruption more difficult than before. If a week or ten days’ discom- fort can be obviated by assisting a tooth through the gum, we fail to see any contraindication to such a procedure. DISEASED TEETH The influence of diseased teeth upon the proper mastication of the food and indirectly upon digestion and nutrition has long been recognized. During the past two decades the role of such teeth as potential foci for disseminating general infection has assumed an importance secondary only to that of diseased tonsils. Many factors combine to promote faulty structure and early decay of the teeth. Defective calcium metabolism from whatever cause in the early years when enamel formation is active is perhaps a foremost caus- ative factor. This is best exemplified in rickets. In syphilis the teeth are notoriously diagnostic of the disease. In typhoid and many of the HARELIP AND CLEFT-PALATE 193 acute infectious diseases inroads upon the normal tooth structure are often marked, conforming closely to the bad effects on the nutrition of the body as a whole. When to such direct causes of tooth decay are added the factors of improper diet, poor heredity, malformation of the jaws and palate, adenoid obstruction, and lack of cleanliness of the mouth it is apparent why the demands made upon the dentist for therapy are often paramount to those made upon the physician. The clinician should make the examination of the teeth a matter of routine, and in the absence of other disease foci in the body will do well to consider bad teeth as perhaps the salient etiologic factor underlying the following conditions: anorexia, bad breath, stomatitis, headache, unexplained temperature elevation, rheumatism, cervical adenitis, sec- ondary anemia and malnutrition, faulty nervous control, chorea, and exceptionally even epilepsy. In all such cases the indications are obvious. The argument often advanced that diseased teeth of the first set require no dentistry because they will soon be replaced by a good second set is analogous to the reasoning of the dirty housekeeper who relaxes her energy completely in view of a remote moving day. HARELIP AND CLEFT-PALATE Harelip is a vertical cleft in the upper lip resulting from arrested embryonic development. This defect may or may not be associated with cleft-palate, and varies from a slight indentation in the border of the lip to a deep fissure, which may be bilateral, extending into the nos- tril, complicated by non-union of the palate. In any case the deformity will be easily understood if we recall that the normal development of the face depends upon the union of the central or frontonasal process with the two lateral superior maxillary processes. Posteriorly, this union is completed in the median line of the palate, and anteriorly, on either side external to the incisors, in the soft parts beneath the nostril. Etiology.—The malformation is more frequent in males than in fe- males, and in some instances can be ascribed to heredity. Not infre- quently with cleft-palate other congenital defects coexist. The true cause of the arrest in development is unknown. Varieties.—Both harelip and cleft-palate may be complete or in- complete, unilateral or bilateral. When the harelip is double, cleft-palate also almost always exists. Median harelip is of exceptional occurrence. Symptoms.—The character of these deformities is wholly apparent. In the simple forms of harelip the disdavantages may be merely cos- metic. When there is a cleft in the palate, however, suckling will be interfered with, deglutition will be difficult, and if the child goes un- treated and survives, articulation will be imperfect. Treatment.—The treatment of both harelip and cleft-palate is es- sentially surgical. The former defect, if uncomplicated, may usually be satisfactorily obliterated by an operation of the Konig or Nelaton type. Cleft-palate offers more serious obstacles. Brophy’s operation secures an approximation of the edges of the cleft by the gradual tight- ening of silver wire sutures traversing two lead plates, each of which is fitted to the lateral portions of the alveolar arch. The operation on the 194 THE PRACTICE OF PEDIATRICS hard parts is deferred until the child is fourteen to eighteen months of age. When the cleft is small, this procedure may be excluded in favor of a mQre direct method. An operation during the first months of life involves considerable risk, but offers better possibilities for good de- velopment of the nasopharynx than an operation deferred until the third or fourth year, after the growth of the teeth. The appropriate course to adopt in any case should, therefore, be left to the surgeon. In young infants with cleft-palate spoon feeding or gavage is fre- quently necessary. Good results in some cases are reported to have followed the use of a special nipple with a flange on either side, designed to bridge over the fissure in the palate. MALFORMATION OF THE ESOPHAGUS Malformation of the esophagus is of infrequent occurrence, and when present is usually accompanied by other congenital deformities. Fig. 21.—Atresia of the esophagus with esophagotracheal fistula. Anterior view. A, Tongue; B, larynx; C, blind esophageal pouch; D, lungs; E, stomach; F, trachea; G, liver; H, lower end of esophagus, which communicates with the trachea. (From a dissection by Losee.) In most instances the differentiation of the esophagus from the trachea and bronchi, in the metamorphosis of the embryonic foregut, has been incomplete. ACQUIRED STRICTURE OF THE ESOPHAGUS 195 The list of possible abnormalities includes the following: (а) Total absence of the esophagus. (б) Diesophagus, involving partial or complete reduplication of the esophagus. (c) Esophagotracheal fistula, with or without obliteration of the lumen of the esophagus in a portion of its extent. (d) Division of the esophagus into upper and lower non-communi- cating pouches. (e) Congenital stenosis. (/) Congenital dilatation. The symptoms caused by these conditions depend on the obstacles opposed to deglutition. Regurgitation of food and accumulated mucus is constant, accompanied by suffocative attacks due to the entrance of material into the respiratory tract. Congenital dilatation above the diaphragm may produce the symptom of rumination. In a large majority of the cases congenital malformation of the esoph- agus results in death before the tenth day from asphyxia, aspiration pneumonia, or starvation. Gastrostomy offers the only possible means of prolonging the pa- tient’s life till surgery directed at the primary defect can justifiably be attempted. Illustrative Cases.—An autopsy on an infant a few days old referred to the Babies’ Hospital showed that the trachea communicated with the esophagus just above the bifurcation. The esophagus was normal at its upper portion, dilated lower down, and formed a blind diverticulum which ended below the level of the tracheal bifurcation. Above the diverticulum the esophagus communicated with the trachea through an opening in its anterior wall. Below the diverticulum the esophagus was smaller in caliber than normal, but it was pervious and communicated with the stomach. A probe could be passed upward through the esophagus into the larynx. A baby seven days old took the bottle greedily and, after swallowing about 2 drams, regularly returned the milk through the nose. He would nurse vigorously with the milk streaming from the nose. ACQUIRED STRICTURE OF THE ESOPHAGUS Practically all cases of this nature are the result of the swallowing of a corrosive poison. In one of our own patients carbolic acid was the cause. Chevalier Jackson has reported several cases due to commerical lye used for cleansing purposes, and warned strongly against the danger of leaving such substances carelessly in places accessible to children.1 1 Jour. Amer. Med. Assoc., July 2, 1921. VIII. DISEASES OF THE STOMACH, INTESTINES, AND PERITONEUM THE STOMACH Anatomy.—During fetal life the position of the stomach is almost vertical, at birth slightly oblique, the obliquity increasing with age. At birth the stomach is almost cvlindric, and, according to Pfaundler, between the time of birth and the seventh month the fundus of the stomach increases to fully twice its original length, so that at about the end of infancy the stomach lies in a somewhat oblique position, passing from behind forward and downward. The diaphragm is penetrated by the esophagus at about the level of the ninth dorsal vertebra, while the cardia is about on a level with the tenth. The pylorus, though usually situated in the median line, may occasionally be found to the right of it. Capacity.—The capacity of the infant’s stomach is, even up to the present day, a subject of more or less speculation, due, no doubt, to the fact that during life aspirations are unreliable on account of the fact that food passes almost immediately into the duodenum, and methods of experiment on the cadaver require an amount of pressure (14 to 30 c.c. of water) that does not exist in the normal state during life. The stomach undergoes a systolic contraction after death, and thus the distention with fluids is artificial. The absolute capacity, according to Holt, Rotch, Pfaundler, and Fleishmann, varies, depending on the method of examination employed. According to Holt’s observations, based on postmortem examinations of 91 infants, the capacity at birth is ounces; at three months, ounces; at six months, 6 ounces; at twelve months, 9 ounces. This subject is discussed on page 38. Gastric Digestion.—Digestion in the stomach is not so important in the infant as in the adult. The function of the infant’s stomach is mainly that of a reservoir, the digestive processes being only preliminary. The principal change in the milk, so far as the stomach is concerned, occurs in connection with the casein curd, and up to the present time it is well established that protein digestion in the stomach does not go beyond the stage of peptone formation. Pepsin is found in large amounts in the infant’s stomach, and, according to some observers, occurs as early as the fourth month of fetal life. The reaction of the stomach contents is usually acid inside of fifteen minutes after ingestion of food, but free hydrochloric acid is not present till thirty or forty-five minutes after, the reason being that hydrochloric acid combines with the casein and milk salts. The coagulation of milk, which is the first change that it undergoes, is brought about through the agency of the rennet ferment. The casein coagulum of cow’s and of human milk is essentially different, the former being a firm mass, containing in its meshes the fat of the milk, the latter being in fine flocculi, with little of the fat, and readily acted on by the 196 THE STOMACH 197 stomach juices. Due to the influence of pepsin and hydrochloric acid solution of the coagulum begins; this occurs more rapidly in woman’s milk on account of the lower casein content and the small size of the curds. During the first half-hour the fluid portion or whey begins to leave the stomach, and at this time a considerable portion may be found in the intestine, and at the end of an hour in a young infant the stomach may often be found empty. In a bottle-fed baby the coagula are larger, solution is retarded, and consequently the food is retained longer. If the milk is boiled, solution is more rapid and gastric retention lessened. Fig. 22.—Normal stomach of a newborn infant. Some of the opaque mixture has immediately passed through the pylorus and reached the jejunum (J). Some observers believe a fat-splitting ferment to be present, but this, if present in the stomach, plays but a small role in digestion. Motility.—The duration of digestion varies of necessity with the age of the infant and the composition of the food. In general terms it may be stated that in breast-fed infants digestion is completed in one and one-half to two hours; in artificially fed infants taking raw milk, in about one to two hours longer; and in those taking boiled milk, in a little less time. Cannon demonstrated that an acid reaction of the contents of the pyloric portion causes the pylorus to open, while an acid reaction in the duodenum causes it to remain closed. After the coagulation of the casein 198 THE PRACTICE OF PEDIATRICS of the milk the whey is readily acidified and passes the pylorus first, together with the carbohydrates. As the protein requires a longer time to combine with the acid of the stomach it is some time before free acid is present, and the exit of the protein from the stomach is, therefore, delayed. The fatty acids and neutral fats are the last to pass the pylorus, because of the longer time required for the fatty acids to be neutralized by the duodenal secretions; and the pylorus, therefore, remains closed because of duodenal activity. The opening and closing of the pylorus, according to these investigations, depends chiefly on the reaction of the gastric contents, which is the most vital factor in the motor activity of the stomach. THE MANAGEMENT OF VOMITING BABIES The baby who habitually vomits or regurgitates his food is one of the most troublesome patients with whom we have to deal. In such cases the possibility of existing pyloric stenosis or of rumina- tion must be excluded. Excellent results, in feeding these habitual vom- iting children, have been gained by the use of cereal decoction and a fat- free milk. One ounce of barley flour to the pint of water is cooked for thirty minutes, and water added to make one pint at the completion of the boiling. The child is fed one-third skimmed milk to two-thirds barley water, or equal parts of skimmed milk and barley water, depending upon the patient’s age and condition. Unless the child is very young the interval between feedings should be three hours or longer, and absolute quiet should be enforced for one and one-half hours after feeding. The handling and tossing about of the vomiting child is one of the best ways of keeping up the trouble. If constipation results from such a diet, mag- nesia in sufficient amount may be added to the daily ration. It is not to be expected that a patient will grow on the above diet. When the vomiting is controlled, the food strength may be advanced by the use of whole milk, and later by the addition of milk-sugar. The addition of 20 grains of bicarbonate of soda to the day’s ration is of de- cided benefit in very troublesome cases. By some infants fresh cow’s milk will not be tolerated, even in very weak dilution. In such instances we have been successful in using evap- orated milk to which cane-sugar has not been added. From 1 dram to | ounce is added to the amount of barley water given at one feeding. The more severe and persistent cases call for trial of the thick cereal feeding described on page 85. The remarkable effects of this mode of treatment in occasional cases can hardly be exaggerated, and the range of its application has been greatly widened in the past few years. Stomach Washing.—Nearly all habitually vomiting infants will im- prove more rapidly if they have a stomach washing every day for a week, and every two or three days thereafter, as may be necessary. For vom- iting in rumination see p. 206. Additional consideration has been given the general subject of vomit- ing in infancy in a preceding chapter (p. 100)'. VOMITING OF OLDER CHILDREN 199 While vomiting does not constitute a disease in itself, it is a condition of such frequency and occurs in such widely varying circumstances that any work relating to diseases of children would be incomplete without its consideration. Certain facts concerning this subject have already been emphasized (p. 100). The most frequent causes of vomiting depend solely upon the func- tions of the stomach. When the stomach is overfilled, vomiting may re- sult. When substances sufficiently irritating come in contact with its lining mucous membrane, whether they are swallowed or are produced by fermentation in the stomach contents, they are ejected. Wffien there is an inflammatory involvement of the mucous membrane of the stom- ach, either acute or chronic in character, the organ becomes intoler- ant of the blandest of fluids. Another condition involving the structure of the stomach, but only occasionally seen in children, is ulceration, which is usually multiple. Vomiting is the prominent, in fact, usually the only, symptom. Dilatation of the Stomach.—In this condition the food does not pass readily into the intestine, but remains in the stomach and undergoes changes which produce sufficient irritation to cause vomiting. Pylorospasm.—In pyloric obstruction or spasm the food is prevented by the narrow pyloric opening from passing into the intestine, one feeding follows another, the stomach becomes overloaded, and, by reason of fer- mentative change in the residue, sufficient irritation is produced in con- nection with the spasmodic contractions of the stomach peculiar to the condition, to induce vomiting. Causes Remote from the Stomach.—Delayed emptying of the stom- ach is not infrequently an indirect cause of vomiting. It is not gen- erally appreciated that persistent constipation is a cause of prolonged retention of the stomach contents, although fecal retention unques- tionably has an influence in prolonging stomach retention. This has been brought out in our z-ray studies. In order for the stomach to function normally it should be empty at least by four hours after a meal. When food is added to undigested stomach contents vomiting is sooner or later bound to appear; in this way mechanical agencies, such as ptosis, angulations, and the greatly elongated sigmoid, may be indirect factors in producing vomiting of a habitual nature (p. 220). In intestinal obstruc- tion, whether due to intussusception, volvulus, peritonitis, abnormalities of structure, or impacted feces, vomiting is an invariable accompaniment, continuing at irregular intervals until the obstruction is relieved or until the child dies. The exanthemata and lobar pneumonia are very commonly ushered in by vomiting if the onset is sudden and intense. In appendicitis in children vomiting is usually one of the early symptoms; so also, in the different forms of meningitis, it is often an early symptom, and may con- tinue persistently during the first few days of the illness. In nephritis, with uremia, vomiting is usually present. Vomiting may be caused by fright, by shock, or by a strain of any nature, as in whooping-cough, or may be of purely nervous origin. VOMITING OF OLDER CHILDREN 200 THE PRACTICE OF PEDIATRICS Illustrative Case.—A girl patient four years old, pale and thin, had the history of vomiting for more than a year, beginning with rather a protracted, badly managed attack of indigestion. At first there were but one or two attacks a day. Later they became more frequent, and for a few weeks before the child came under personal ob- servation the vomiting had occurred at the table with nearly every meal, before the meal was completed. The mother was most anxious and apprehensive regarding the child’s condition, was always with the patient, always fed her, and always worried constantly throughout the meal, fearing an attack of vomiting. The most thorough means of examination of the stomach failed to show anything wrong with it. After some days’ observation it occurred to the writer that the presence of the apprehensive mother, in whose mind the condition of the child and the vomiting were uppermost, might be a factor in causing the vomiting. He accordingly directed that the child take her meals in the kitchen with the maid, and that the possibility of vomiting should not be mentioned. The mother was directed not to come in contact with the child in any way during the meal. We were much gratified and not a little surprised when the vomiting promptly ceased. After a few months of this regime the maid was taken ill, and the mother for one day attended to the feeding. Again the child vomited as before. The management of the different types of vomiting will be referred to in the consideration of the various diseases with which it is associated. ACUTE GASTRITIS AND ACUTE GASTRIC INDIGESTION Not a little confusion exists respecting the differentiation of acute gastritis and acute gastric indigestion. Cases of gastric indigestion are often diagnosed as gastritis. Actually acute gastritis in children is a very rare condition, while acute gastric indigestion is very frequent. Acute gastritis in the young is usually due to the ingestion of corrosive or irri- tant drugs. Food, unsuitable in character or quantity, or food which may have undergone chemical or bacterial change, may produce pro- nounced vomiting, usually transient in character. Inflammation of the mucous membrane of the stomach may be produced in this way, but according to autopsy findings it is most unusual. Cases of persistent vomiting which are often diagnosed as gastritis are not infrequently due to obstruction at the pyloric outlet dependent upon the presence of hypertrophic stenosis (p. 215), or pylorospasm (p. 214). Any of the various forms of meningitis or encephalitis may be preceded or accompanied by persistent vomiting. Acute intestinal obstruction should be kept in mind as a cause of persistent vomiting. Acute acid intoxication may occur at any age and should always be taken into consideration before making a diagnosis of acute gastritis. Autopsies on infants dying from acute gastro-enteric diseases, such as cholera infantum, rarely show any actual stomach lesion, although there may have been persistent vomiting for two or three days. Acute gastric indigestion is manifested in sudden repeated vomiting, often with fever, always with prostration, and with apparent disgust for food. The temperature may be high—104° to 105° F.—or normal through- out the case. After a few hours there will often be evidence of bowel involvement. The stools are undigested, greenish in color, and contain a moderate amount of mucus. There may be moderate abdominal distention. The symptoms other than that of emesis may appear of little significance. Treatment.—A high enema should always be given as the initial treat- ment in any illness of any nature in which there is acute vomiting with an absence of free bowel action. If the vomiting is continued, the man- agement of the case, regardless of the exciting cause, is to wash out the ACUTE GASTRITIS AND ACUTE GASTRIC INDIGESTION 201 stomach at least once and to give no food by mouth. If the case is of more than twelve hours’ duration in an infant or twenty-four hours’ in an older child, colon flushings should be carried out to supply fluids to the organism (p. 855). A remedy of much value, both for infants and older children, is a solution of bicarbonate of soda, 5 grains in 6 ounces of water, given hot in teaspoonful doses at intervals of a very few min- utes. Diet.—After twelve or twenty-four hours’ abstinence from food, small quantities of water or some very weak food may be given ten- tatively if the child craves it. Whey, skimmed or diluted milk, barley water, weak tea, chicken or mutton broth may be tried in teaspoonful doses every half-hour. Usually cold foods will be retained better than those that are heated. If the food or water is rejected, a further stomach rest of from eight to twelve hours may be ordered before the feeding is resumed. Treatment of Protracted Cases.—In the protracted cases the stom- ach should be washed, at least once daily, with a 5 per cent, solution of bicarbonate of soda. It is never wise, in the event of vomiting, to attempt forced feeding, as nothing will be gained; in fact, the vomiting may be continued indefinitely, and chronic gastric indigestion estab- lished, as a result of injudicious attempts at feeding. For the persistent vomiting of infants, gavage (p. 853) may also be used. A food which is rejected when swallowed will often be retained when put into the stom- ach through a tube. It is from the lack of fluid that the child suffers most in the case of protracted vomiting. In such cases colon flushing is particularly valuable, as they are rarely sufficiently severe to require hypodermoclysis. Applications of heat or counterirritation over the stomach area are of no real service, but at times are grateful to the patient. One who has treated many of these cases of acute indigestion with different forms of medication, including calomel, small doses of ipecac, oxalate of cerium, opium, etc., cannot fail to have been far more impressed with their use- lessness than with their beneficial influence. An enema, the recumbent position, and the withholding of food, with nourishment, or fluids such as normal salt solution, by the bowel, have given the best results. When the child craves food and asks for water after an abstinence of several hours, feeding may be tried, but the fact that he asks for it is by no means a guarantee that what is given will be retained. In exceptional cases rectal feeding may be required. Treatment of Persistent Vomiting by Drugs.—In pronounced, urgent, frequent vomiting of undoubted gastric origin, morphin hypodermically may be required. The morphin should be guarded by atropin and given in doses of 1/50 to 1/40 grain for a child one year old, to 1/10 grain for a child from eight to twelve years old. The relation of the dose of mor- phin to that of the atropin should be as 1 is to 1/20. Thus, a child who is given 1/30 grain morphin should have combined with it 1/600 grain atropin; with 1/10 grain morphin there should be given 1/200 grain atropin. It will rarely be necessary to repeat the morphin more than once, two injections being given at an interval of from four to six hours. In all 202 THE PRACTICE OF PEDIATRICS cases the usual feedings must be resumed gradually. A trial of differ- ent foods will soon show which will best be retained. CHRONIC GASTRIC INDIGESTION (CHRONIC GASTRITIS) Chronic gastric indigestion develops most frequently in comparatively young infants, and is often associated with, or is a cause of, marasmus and malnutrition. Symptoms.—Vomiting and regurgitation of food are the predomi- nant acute manifestations of the disorder, which, untreated, interferes seriously with the nutrition of the patient. The condition is almost invariably a result of slight but persistent errors in feeding—errors too small to make the child violently ill, but sufficient to keep the stomach in a constant state of unrest. Pathology.—The lesions in these cases are insignificant. There may be some superficial, localized congestion at the pyloric end of the stom- ach; there may be destruction of the superficial epithelium and infiltra- tion of the mucosa with round cells. Treatment.—The management consists in daily stomach washings, sometimes for a long period, and an adaptation of the food to the child’s digestive capacity (p. 198). While there is no one way of feeding these cases, a food of greatly reduced strength must always be given, par- ticularly when cow’s milk is used. As a rule, these children have a low fat and sugar tolerance. Usually the proteins are fairly well taken care of if the function of the stomach is not disordered by too much fat and sugar. GASTRIC HYPERACIDITY IN CHILDREN A vast amount of literature has appeared relating to hyperacidity and associated conditions of the gastric contents in adults. That a similar condition may exist in young children has not been appreciated. A clin- ical study of the cases demonstrating high stomach acidity was forced upon us by a symptom complex which was shown by many patients and which corresponded to the symptomatology of gastric hyperacidity in adults. Etiology.—Dietetic errors will usually but not invariably be found responsible for the disorder. In addition to the usual bad feeding habits, taking unsuitable food at irregular hours, eating between meals and the liberal patronage of confectionery stores and soda fountains, the habitual use of orange juice in liberal amounts on an empty stomach before the first meal is significant. In fact, the hyperacidity condition may be due to the taking of orange juice cold and undiluted on an empty stomach before breakfast. Hypomotility and pvlorospasm, both conditions not uncommon in children, cause delayed emptying of the stomach beyond the four hours that is the normal evacuation time for the runabout child. This gives rise to gastric retention, which causes hyperacidity. We have studied 109 children in regard to this point by means of the Roentgen ray, using the stomach-tube as a control in several of the cases. We find causative also the short period allowed between the first and second meal of the day. On account of family habits or because the child is a late sleeper GASTRIC HYPERACIDITY IN CHILDREN 203 the first meal is delayed and not completed before 8.30 or 9 o’clock. The second meal is given promptly at 12 or 12.30, which means that the second meal is given before the first meal has entirely passed through the pylorus, and again there are retention and hyperacidity. In order that the appetite and digestion may be normal there must be no food residue in the stomach when a meal is given. Further, we have found that a rest period or interdigestive period of from one-half to one hour is required in order that the stomach functions may be carried on normally. It is to be understood that the rest period implies an empty stomach. Symptomatology.—The symptoms in their order of frequency are: abdominal pain that has not been relieved by previous treatment, nausea without vomiting, vomiting at irregular intervals, and loss of appetite. The pain occurs most often before meals when the stomach is sup- posedly empty. In many cases pain is complained of before the morning meal. At times the child is awakened early because of the abdominal discomfort. When asked to locate the pain, the child usually places the hand over the abdomen above the umbilicus. In some the pain is of a colicky character sufficiently severe to cause crying. Vomiting.—With the pain there may be daily morning vomiting, or the vomiting may occur independently of pain, or the child may be nau- seated and vomit before the meal or immediately after. Breakfast is usually the meal vomited. Nausea.—In some there is neither vomiting nor pain, the condition manifesting itself by nausea, most prominent before mealtime, and perhaps relieved by taking food. Appetite.—The appetite is variable. In most instances it is much impaired. In others the child will be eager for food, but is satisfied by a few mouthfuls, complaining of a feeling of fulness, so that further feed- ing must be urged. Many children with an habitually poor appetite are victims of hyper- acidity. Nausea and Eructation of Gas.—This combination is not infrequently seen, and is almost always associated with an indifferent and capricious appetite. Eructations of gas and belching may be the only symptoms complained of. Mothers have stated that the eructation was so pronounced as to be embarrassing. Constipation.—This is usually present; probably the small food intake has much to do with this. In cases in which the condition has existed for a considerable time malnutrition and anemia due to the defective food intake are marked. In mild cases the appetite alone is affected. In 67 recent cases of chronic stomach disorders we have insisted on the test meal and gastric analysis, and have been surprised at the co- operation of the parents. This is to be accounted for probably by the fact that the child is brought for a condition which is believed to be serious. Examination of Gastric Contents.1—Test Meal.—-The test meal con- sists of 2 ounces (60 gm.) of dried bread and 6 ounces (178 c.c.) of weak tea. In one hour the stomach contents are removed by the stomach- tube. The Preparation of the Patient.—The child is wrapped snugly in a 1 By Dr. E. J.

The child is held firmly by the assistant. After the tube has been moistened in warm water, it is passed to the posterior part of the pharynx. Older children are asked to swallow, but in dealing with the younger it is necessary to pass the tube without co-operation. A certain definite resistance is encountered when the tube strikes the greater curvature of the stomach. Usually the evacuation of the stomach contents begins immediately. The flow is accelerated by coughing, crying, and vomiting. It is frequently necessary to begin the evacuation by aspiration. We find the Hess bulb satisfactory for this procedure (p. 211). Technic of Gastric Analysis.—Three separate portions of 10 c.c. of unfiltered gastric juice are placed in three small beakers. To the first portion 3 or 4 drops of phenolphthalein are added, and this is titrated with tenth-normal sodium hydroxid until a deep permanent purple is obtained. The number of cubic centimeters of tenth-normal sodium hydroxid used in titrating is then multiplied by 10, giving the total acidity of 100 c.c. of gastric contents. Three or 4 drops of alizarin is added to the second beaker, and this is titrated until a permanent violet is ob- tained, when the reading on the buret is made. This result is subtracted from the number of cubic centimeters used with phenolphthalein as the indicator. This is multiplied by 10 to obtain the amount of combined hydrochloric acid in 100 c.c. of gastric juice. To the third beaker 3 or 4 drops of Toepfer’s reagent is added, and this is titrated until the red disappears and yellow makes its appearance. The buret is read and the result multiplied by 10. This gives the amount of free hydrochloric acid in 100 c.c. Results of Examination of Gastric Contents— Among 67 cases, 44 showed a total acidity over 60; 36 over 70; 24 over 80; 3 over 90, and 2 over 100. The 2 cases showing a total acidity over 100 were those in which there was a food residue remaining from the meal prior to the test meal. Of the 23 that were under 60, the findings were: 14 between 50 and 60; 4 between 40 and 50; 4 between 30 and 40, and 1 between 20 and 30. We have come to look upon the normal acidity in children as ranging between 30 and 40. In the same series we determined the amount of free hydrochloric acid in the gastric contents of 59 patients. Fifteen showed the amount of free hydrochloric acid to be between 1 and 10; 17, 10 and 20; 8, between 30 and 40; 4, between 40 and 50; 2, between 50 and 60; 3, between 60 and 70, and 1, between 70 and 80. There were but 3 cases in which we found an absence of free hydrochloric acid in those investigated. Management.—Three full meals are allowed: breakfast at 7.30 a. m., dinner at 12.30, a cracker at 3.30, and supper at 6 p. m. Kaw fruits, fruit juices, and condiments are forbidden. Solids and liquids are to be given neither very hot nor very cold. Ice-cream and all iced drinks are ex- cluded. Sugar is used scantily. Medication consisting of a powder com- posed of sodium bicarbonate and bismuth subcarbonate, each 2 grains (0.13 gm.), and magnesium carbonate, 1 grain (0.065 gm.) is given with a half glass of warm water fifteen minutes before each meal. If constipa- ULCERATION OF THE STOMACH 205 tion is a factor, from 15 to 30 drops of aromatic fluidextract of cascara sagrada is given after each meal, and not in one dose at bedtime. Results of Treatment.—The outcome of the treatment has been most satisfactory. Children rarely have gastric, pyloric, or duodenal ulcers. Malignant disease of the stomach is so rare an occurrence that it can be excluded. Relief with few exceptions is prompt, but the diet and the medication should be continued for several weeks. We have known relapses to occur a year or more after the cessation of treatment. When there has once been a definite hyperacidity, there is a strong tendency for it to return, and some of these patients are unquestionably in line for surgical procedure later in life. HEMORRHAGE FROM THE STOMACH* VOMITING BLOOD With the exception of hemorrhagic disease in the newborn, the vom- iting of blood by infants is due to ulceration of the stomach (p. 205), to purpura fulminans (Henoch’s), or to accidental causes. A boy six years of age died on the third day with purpura fulminans. There were profuse hemorrhages from the stomach, from the mucous surfaces, and under the skin. In two proved cases extensive ulceration of the stomach was found at autopsy. Accidental sources of hematemesis include the swallowing of blood, which may take place as the result of a nasal hemorrhage, or from a blow or fall causing injury to the nose or mouth, or from the presence of a foreign body in one of the nostrils. Injury to the pharynx also may be followed by hemorrhage sufficient to cause vomiting if the blood is swallowed. Illustrative Case.—A case of hematemesis in a well-nourished breast-fed infant five months of age was productive of a great deal of anxiety. The vomiting of blood con- tinued for several days without the slightest evidence as to its source. This occurred two or three times a day, usually shortly after nursing, the quantity of blood being especially large after the early morning nursing. There were no cracks or fissures in the mother’s nipples, nor could blood be made to exude from any portion of the nipples on reasonably strong pressure. Convinced, nevertheless, that the source must be the breast, the writer applied a breast-pump, making use of as strong suction as possible, and obtained milk with a large mixture of blood. Evidently there had been a rupture of some of the smaller blood-vessels in the gland behind the nipple. At the first nursing the child was very hungry and tugged vigorously at the breast, which doubtless explains why the early morning vomiting showed the most blood. In hematemesis of the newborn the patient should have the advan- tage of the human blood injections (p. 185). ULCERATION OF THE STOMACH Ulceration of the stomach is usually associated with marked gastric disturbance, such as occurs in gastritis and in the different forms of mal- nutrition. Notwithstanding a large autopsy experience among infants and young children, the writer has yet to see a perforating ulcer, tuberculous or of other type. In fact, aside from those in the newborn he has seen at autopsy only 2 cases of gastric ulceration. In 3 other cases the diag- nosis of ulceration was made because of hematemesis. Illustrative Cases.—A child one month old repeatedly vomited blood, and eventually bled to death. At autopsy about 2 ounces of coagulated blood were found in the stom- 206 THE PRACTICE OF PEDIATRICS ach. The gastric mucous membrane was the seat of many ulcers, varying in size, none exceeding inch in diameter. Another patient, three months old, had chronic gastro-enteritis with occasional vom- iting of blood and died from exhaustion, the autopsy showing multiple small ulcers in the mucous membrane of the stomach. That gastric ulcerations, even of a mild degree, play any great part in the digestive disorders of infants and young children is disproved by the infrequency of the lesion at autopsy. In treating cases of gastric disorder by stomach washing it is com- paratively rare to find blood in the water siphoned off. At rare inter- vals the water may be tinged with blood, but the washings invariably should be continued in spite of this, as we have never known any severe hemorrhage to follow. The blood which appears under these conditions is doubtless from the capillaries of the congested mucous structure. Treatment.—In the event of persistent vomiting of blood of small or large amount, which cannot otherwise be accounted for, the walls of the stomach are to be regarded as the source of the hemorrhage. Under these conditions oral feeding should be discontinued and the nutrient enema (p. 98) should be brought into use. Bromid and chloral, or stimulants, if necessary, may thus be given with the food. Adrenalin 1 : 1000 solution in small doses may be given hourly and continued for twelve hours after the vomiting ceases. After thirty-six hours water may be given in small amounts; and the usual milk mixture diluted one- half, in small quantities of 2 or 3 ounces, may also be allowed. The normal diet should not be resumed in less than a week, even in the event of entire absence of vomiting during this period. Rumination is a rather infrequent condition, and one which is likely to be overlooked unless one is very careful to watch the vomiting child after feedings. It is characterized by the regurgitation of food after almost every feeding, part of which is actually vomited and the rest is reswallowed. Etiology.—This condition occurs most frequently in children a few months of age and is often not diagnosed until the vomiting has been going on for several weeks. Rumination may also be present in older children. When practised at this age it has become a habit and occurs especially in the neurotic. In infants there may be an associated pylorospasm. Symptoms.—The clinical picture is fairly characteristic, closely re- sembling that afforded by the ruminating animals, such as the cow chew- ing the cud. A few minutes after the baby gets the bottle, he will start peculiar suction movements, and presently some of the milk can be seen in the mouth, a part may spill out and part will be chewed and reswallowed. This proceeding will be repeated until the child has emptied the stomach or fallen asleep. Such children are often much emaciated from the prolonged loss of food. Treatment.—A popular method of treatment is to give food so thick that it cannot readily be regurgitated. A mixture containing 1| ounces of barley flour to 1 pint of skimmed milk is cooked in a double boiler for one hour. On cooling, this forms a thick gelatinous mass. It is fed with RUMINATION PYLORIC OBSTRUCTION IN YOUNG INFANTS 207 a spoon to the child in quantities to which he is accustomed at intervals of three to four hours. (See p. 85.) Strauch, of Chicago, observed that the nostrils had to be open to aid the child in regurgitating the food. He therefore improvised a clamp to keep them closed for a certain time after feedings. In this way he con- trolled the vomiting to a great extent. In a private patient the habit was broken by substituting another habit, less harmful. The ruminating infant was taught to use the pacifier. Sucking the pacifier proved more entertaining than ruminating. Sedgwick advised strapping the lower jaw firmly to the upper by means of adhesive plaster, thereby preventing the rhythmic jaw action neces- sary for regurgitation. A device which has served well is shown in Fig. 23. Fig. 23.—Device to prevent rumination, showing manner of applying it under chin. Note the two buckles on top and the strap which runs posteriorly and is fastened at the distal end by a buckle. The patient was five months old, weighed 7 pounds, 11 ounces, and showed extreme emaciation. The thick gruel feeding (p. 206) was of use only after the appliance effectually prevented the manipulation of the lower jaw and the tongue. The patient gained 18 ounces in two weeks and in four weeks had gained 2 pounds and 7 ounces.1 PYLORIC OBSTRUCTION IN YOUNG INFANTS Cases of pyloric obstruction may be grouped under three main di- visions : 1. Simple pylorospasm in which there is no hypertrophy (Figs. 29-31). 2. Hypertrophic stenosis, in which there is tumor with marked increase in the circular fibers (Figs. 32-35). 3. Combined hypertrophy and spasm. Age and Sex Incidence.—In this disease the age is of great impor- tance as a diagnostic point. Of 38 patients reported by Still, one be- gan to vomit within twenty-four hours after birth and six others within the first week. Pfaundler found that the first vomiting indicating the onset of the disease was between the fourth and fourteenth days in 50 per cent, of the cases; from the second to third week in 25 per cent.; and from the third to sixth week in 25 per cent. In over 60 of our own cases the vomiting never developed later than the sixth week. In one 1 Kerley and Lorenze, Arch, of Pediatrics, May, 1921. 208 THE PRACTICE OF PEDIATRICS case a tumor was palpable when the infant was six days old. The symp- toms may begin a few hours or days after birth, or they may not appear until the third or fourth week; occasionally not until the second month, and very rarely not until a later date. Instances of hypertrophy and stenosis of the pylorus coming on in adult life have been frequently re- corded, and these may not infrequently be due to a persistence of the condition from early life. According to Ibrahim’s investigations of 266 cases, the total number of cases shows a rapidly ascending curve in the first month and a reduced frequency with advancing age. In the case of a baby five or six months of age, with a history of vom- iting over a period of three or four weeks, the age alone is evidence against pyloric stenosis. In exceedingly rare cases seen in older children vomiting due to stenosis might be confounded with cyclic vomiting. Holt saw one such case. 'Total nutnbeh of cases Weeks ofLIfe Fig. 24.—Drawn in accordance with Ibrahim’s 266 cases (Pfaundler and Schlossmann’s System, 1912). Sex.—No great stress is to be laid on sex in the diagnosis of this dis- ease. The large number of male patients, however, contrasts remark- ably with the corresponding small number of females. Out of a collec- tion of 42 cases in which this point was noted, 35 were males (Still). According to Ibrahim, males are affected about four times as often as females. Cases have been met in the same family (Freund). This oc- curred once under our observation. In another instance a brother of the patient’s mother had died in infancy with symptoms typical of pyloric obstruction. Some authorities state that when the disease occurs in girl babies, it is usually of a mild form. One of our cases in which the patient was a girl was exceptionally severe despite the fact that recovery occurred without operation. Etiology.—Pyloric stenosis is one of the diseases concerning which a great amount of theorizing has been done, especially in the early days, PYLORIC OBSTRUCTION IN YOUNG INFANTS 209 when few autopsy specimens were at hand. Most of the various sur- mises have been discarded, such as the probability of the stomach under- going an agonal contraction, thus producing the thickening (Pfaundler). Many new views, however, have been offered, as the various names of the disease might suggest. Prominent, and among the most universally recognized, theories up to 1897 were those of Hirschsprung and John Thomson. According to the former, the disease was due to a congenital organic defect, resulting from a primary pathologic hypertrophy of the pyloric wall, which constricted the lumen. Thomson contended that the essential lesion was not muscular, but primarily nervous: “A functional disorder of the nerves of the stomach and pylorus leading to ill co-or- dinated and therefore antagonistic action of their muscular arrange- ments.” This latter view corresponded very closely to Still’s theory of “stomach stuttering.” There is, to date, no convincing evidence that the spasm is set up by erroneous feeding or by hyperacidity. In 7 of 11 cases Feer found the total acidity varying from 50 to 105, and free hydrochloric acid from 0 to 50. Similar results have been obtained by other observers (Ram- sey, Bernheim, Karo, Engel, Freund, Miller, Clark). Miller and Will- cox (1901), in a series of carefully conducted investigations, attempted to show that pylorospasm may be due to hyperacidity, and that in hy- pertrophic stenosis, spasm, if present, is produced by some other cause. In hypertrophic stenosis hyperacidity is very common. Of recent years most authorities have regarded the condition as primarily spasmodic, and probably due to gastric or duodenal irritation or nervous disturbances. According to this theory the hypertrophy is secondary and depends to a large extent upon the degree of spasm. The possible existence of a certain amount of antenatal hypertrophy may be appreciated when one considers that the pylorus begins to form as early as the third month of fetal life. Such hyperplasia has actually been found by C. T. Dent in a seven months’ fetus. P3rlorospasm has its analogue in certain other spasmodic conditions of the circular fibers, such as constipation due to a spastic condition of the sphincter ani, and various allied conditions of the larynx and bronchi. By some observers, however, the essential condition in pyloric stenosis is regarded as a pri- mary hypertrophy with secondary spasm. Pathology.—The postmortem findings are remarkably uniform. The alimentary canal below the pylorus is perfectly normal. The esophagus is sometimes noticeably dilated, sometimes of normal caliber. The stomach is usually much dilated, the lower border being fre- quently below the umbilicus; the wall at the cardiac end is as thin as normal, but elsewhere much thicker, especially toward the pylorus. Occasionally the cardia may assist in the general hypertrophy. The pyloric part of the stomach consists of a rigid, resistant, cartilaginous mass of a bulging or nearly cylindric shape. The swelling appears like a separately interpolated insertion between the stomach and duodenum. When looked at from the duodenum, the pylorus seems almost closed, the mucous membrane being puckered by the contraction of the hy- pertrophied muscular wall, not unlike that of the os uteri. No fibrous stricture is present, and the whole narrowing seems to be due to com- 210 THE PRACTICE OF PEDIATRICS pression by hypertrophied muscle. The tumor enlargement varies from 2 to 3 cm. in length, and from lb to 2 cm. in thickness. On section, the thickening appears to be due to the hypertrophy of the circular fibers, which may be two or three times their normal thickness. Finkelstein reported a case in which the thickening was due to an increase in the Fig. 25.—A, Drawing to indicate normal pylorus. B, Hypertrophic pyloric stenosis. A B longitudinal fibers. The lumen varies in size. In some instances it barely admits a fine probe. Walbach, in one case, found the lumen 2 cm. in diameter. Occasionally a slight connective tissue increase is found in addition to a slight thickening of the mucosa and submucosa. Catarrhal Fig. 26.—Congenital hypertrophic pyloric stenosis: Section through pylorus to show thickened muscular ring. P, Hypertrophied pyloric muscle. or inflammatory changes are usually absent. The test of functional potency by hydrostatic pressure is fallacious, for the redundant folds of mucous membrane may act as valves. An observation of the illustration (Fig. 26) showing the cartilaginous ring makes it obvious that spasm here would be impossible. Figure 26 PYLORIC OBSTRUCTION IN YOUNG INFANTS 211 further emphasizes the uselessness of drugs or any means other than operative procedures for the relief of extreme obstruction. Symptoms.—Vomiting is the only active symptom of the stenosis, whether it is spasmodic or due to stricture. The history is usually that of an infant, apparently normal at birth, who remains well for two or three weeks or more. The child regains the early loss in weight, the stools are normal, and there is no suggestion of gastric disturbance. Then, without apparent cause, the child, whether breast or bottle fed, begins to reject the food. Vomiting.—The vomiting may occur after each feeding. More fre- quently two or three nursings are retained and then a large amount is Fig. 27.—The Hess bulb. ejected, so that the nurse or mother is impressed with the large amount of vomiting, and volunteers the information that two or three feedings would be necessary to replace the large amount of food lost. In most cases the vomiting is forcible and decidedly explosive in character. Retention.—The stomach of an infant who takes from 3 to 4 ounces at a feeding should be empty at the end of three hours. When food is retained longer than three hours it means, in a vast majority of the cases, an obstruction at the pyloric outlet and is a very valuable sign in pyloric stenosis. A retention of 1 or 2 ounces is not at all unusual and when there is an associated dilatation of the stomach—two or more feedings being retained—the retention has been 4 to 5 ounces. A convenient device for testing the retention is the Hess bulb (Fig. 27). By this device 212 THE PRACTICE OF PEDIATRICS all the contained fluid in the stomach may be aspirated into the glass bulb and measured. Constipation.—With the vomiting is associated constipation. The passages, previously full and normal, become very scanty, and are passed only upon rectal stimulation. Mucus is usually mixed with the feces. The degree of constipation depends upon the degree of permanency of the stricture. In the purely spasmodic cases considerable fecal material will be passed. A lesser amount will be passed in cases of the combined type. Fig. 28.—Visible peristaltic waves. Pyloric obstruction. (John Thomson, Clinical Study and Treatment of Sick Children, 3d ed.) Loss in Weight.—There is rapid loss in weight, as would be expected. We have repeatedly seen such infants reduced to mere skeletons. Appetite.—These patients are voraciously hungry, and will take everything in the form of liquid food that is offered. Water will fre- quently be taken as eagerly as milk mixtures or the breast. Absence of Other Signs of Illness.—There is no elevation of the tem- perature and there are no nervous phenomena. The urine is scanty and of high specific gravity, but shows no evidence of diseased kidneys. The child appears ill only on account of the wasting and moderate pros- tration. PYLORIC OBSTRUCTION IN YOUNG INFANTS 213 Diagnosis.—In all young infants who develop persistent vomiting with constipation, or even persistent vomiting without constipation, the possibility of stenosis of the pylorus should be considered. The Peristaltic Wave.—-'This sign consists of a rounded, circumscribed elevation of the abdominal wall, a lump from 1 to 2 inches in diameter, which forms q,t the left of the median line, sometimes appearing to rise from the margin of the ribs, and passes across the epigastrium (main- taining its original size in transit) to the right hypochondrium, where it disappears. In a few seconds the phenomenon is repeated. Not in- frequently, before the first wave disappears a second will form. The elevation and depression may be sufficient to involve the entire abdom- inal wall (see Fig. 28). The peristaltic wave described occurs in no other condition. Method of Obtaining the Wave.—The wave may best be demonstrated after feeding. The stomach should not be overfull. If the usual feed- ting time is near, 2 ounces of food or water are given. If the child has been recently fed, before giving the food the stomach is washed out. The abdomen is then exposed, and usually before the child has finished the bottle the peristalsis will appear. Occasionally a case is seen in which no peristalsis will be elicited at the first examination. The Tumor.—Palpation of the tumor through the abdominal wall is possible in nearly all cases. Considerable practice is required in order to be able to locate the tumor. We have not been as successful as other writers in demonstrating this conclusive sign. Still was able to palpate the pyloric tumor in 41 out of 42 cases. Palpation is aided by a partially filled stomach that is in active per- istalsis. Differential Diagnosis Between Hypertrophic Steyiosis and Pyloric Spasm and Obstruction of the Combined Type.—The palpable pylorus may be looked upon as a hypertrophic pylorus. In a pylorus, moreover, that has undergone sufficient thickening to be palpable the connective tissue changes are in all probability sufficient to necessitate operation. Constipation is always present in stenosis of the hypertrophic form. There is dilatation of the stomach, and the vomiting is persistent. In the spasmodic type the vomiting appears to occur periodically—per- haps not oftener than once or twice a day. In some cases of simple spasm there may be no vomiting for a day or two, and during this time the stools will be fairly large. The short cessation will then be followed by a return of the repeated emesis. Cases of this type present the best chances for cure without operation. In the combined tijpe, in which there is moderate hypertrophy and spasm, the stenosis, when the stomach is at rest, is moderate in degree. It is possible for a considerable portion of the stomach contents to pass into the intestine if but small quantities of food are given at one time. Illustrative Cases.—A case expected to undergo recovery without operation was of this type. Vomiting occurred sometimes once a day—never more than twice. The active peristaltic wave was present. The stools were fairly large and well digested, from 10 to 15 ounces of food being retained daily. Without apparent cause the child went into collapse and died. The autopsy showed a pyloric canal about 1/16 inch in diameter, and revealed moderate thickening and hypertrophy of the circular fibers.

One hour after the meal, stomach apparently resting, as no more of opaque meal had passed through the pylorus. Roentgenogram made about four hours later, stomach practically empty (Fig. 31). Comment: The irregular emptying of the stomach was undoubtedly due to spasm of the pylorus which relaxed from time to time. Pyloric stenosis would probably have been demonstrated by a uniformly slow emptying; hence the diagnosis of pylorospasm. This case recovered completely without operation.

The pyloric muscle incised according to Downes’ method.1 Roentgen examination sixteen days after the operation showed that the stomach emptied at a normal rate. Comment: The use of atropin was of no avail. Although some claim that atropin is useful in simple pylorospasm, we do not believe it can be depended upon in cases of true hypertrophic stenosis as determined by Roentgen examination. 1 Dovnes, W. A., Congenital Hypertrophic Stenosis, Trans. Sec. on Surgery, Amer Med. Assoc., 1920. 216 THE PRACTICE OF PEDIATRICS the disease was demonstrated by a private patient who began vomiting at three weeks. There was the peristaltic wave, the vomiting several times a day, emaciation, and con- stipation. Operation was partially arranged for. The child had been bottle fed, however, and preparatory to the operation a wet-nurse was solicited in order that the postoperative management might be the more secure. The wet-nurse was supplied and the baby’s stomach was washed daily. In four weeks the vomiting had subsided and the child gained 2 pounds, 2 ounces in weight. There was no further trouble with the case. Here surely was not a case of organic stenosis. Prognosis.—The prognosis is dependent upon many factors. The age of the patient and the nature of the surgical treatment are such that operative procedure will always show a considerable mortality. The severity of the operation and the tender age of the subject are not the only reasons for the high mortality. Many of the patients when they come to the surgeon are so emaciated and reduced in vitality that operation simply hastens the end. In surgical cases of children the surgeon should receive the opinion of counsel as to when and how long a condition may continue and still afford a good surgical risk. Cases With Palpable Tumor.—These infants should be given the ad- vantage of immediate operation. In 1920 Downes1 reviewed 100 cases in which the Fredet-Itammstedt operation was performed for pyloric obstruction. He recommended that medical treatment in doubtful cases be limited to a period not longer than ten days, provided the weight loss during this period did not exceed 20 per cent. The mortality among patients coming to operation within four weeks of onset of symptoms he found to be less than 8 per cent. We are indebted to Downes and Bolling for additional information concerning cases coming under their care during a period of three years and nine months beginning January 1, 1920. Of 181 operations, all except 3 were performed at the Babies’ Hsopital. One hundred forty- five patients were males and only 36 females. The average age was six weeks and five days; and the average duration of symptoms three weeks and five days. A pyloric tumor was felt in every case. In a group of 82 infants under 7 pounds on admission the mortality was slightly less than 27 per cent. In a group of 99 weighing 7 pounds and over, the mortality was slightly less than 6 per cent. The mortality for the whole group was slightly less than 15.5 per cent. In a number of the fatal cases death proved to be due to causes in- dependent of the pyloric condition and the operation. This record reinforces Downes’ contention that operative interference in cases of pyloric obstruction in which medical care is unproductive of prompt improvement is a conservative procedure. His results have been permanent. The Spasmodic Cases.—There are probably comparatively few pyloric cases without involvement of the muscle structure. In such cases the prognosis is good, and all should survive without operation. In the combined cases of spasm and hypertrophy, which represent the largest number of cases, the prognosis is dependent largely upon the degree of hypertrophy and the management. Exclusive of operation, the management of the spasmodic and combined type is the same. 1 Jour. Amer. Med. Assoc., June 24, 1920, vol. 75, pp. 228-232. PYLORIC OBSTRUCTION IN YOUNG INFANTS 217 Surgical Treatment.—The great majority of cases come to operation. In view of the fact that the presence of the tumor is difficult to demon- strate, it is not wise for the physician to depend on this sign. Frank clinical signs and symptoms in 95 per cent, of the cases mean that an organic obstruction exists and that an operation will eventually be re- quired. When the vomiting continues in spite of treatment, and the child shows progressive loss in weight and strength, it is safe to assume that a considerable degree of Irypertrophic stenosis exists and operation should not be delayed. Temporizing is safe only when there is no pro- nounced loss in weight. It is best to operate while the child possesses a good resistance. The Rammstedt operation offers the best results. This operation consists in making a longitudinal incision from 2 to 3 cm. in length through the serosa and the hypertrophied circular mus- cle-fibers of the pylorus down to the thickened mucosa. The duration of the operation, as performed by Downes, is ten to twenty minutes. Postoperative Treatment.—Vomiting after operation rarely causes trouble. Regurgitation, which is troublesome, will occur in some patients. This may be obviated by bringing the force of gravity into use by elevat- ing the head and shoulders of the patient on a high pillow. These children need fluid badly, and this may be supplied, during the first hours after the operation, by the “Murphy drip” or better by hypodermoclysis. If breast milk is not obtainable, fresh cow’s milk or condensed milk, suitably diluted, may be used. The following directions cover the procedure developed at the Rabies’ Hospital, New York City, in conjunction with the Fredet-Rammstedt operation: On admission a lavage is to be given and a two-hour retention test done, using 60 cc. of breast milk. Two hours after operation give 15 cc. of water. Three hours after operation begin feedings on a three-hour schedule giving each of the following mixtures for two successive feedings before advancing to the next on the list: 1. Breast milk 4 cc. Barley water 4 “ 2. Breast milk 8 “ Barley water 4 “ 3. Breast milk 12 “ Barley water 4 “ 4. Breast milk 16 “ Barley water 4 “ 5. Breast milk 20 “ Barley water 4 “ 6. Breast milk 24 “ Barley water 4 “ Then give 30 cc. every three hours for eight feedings in twenty-four hours. In- crease 5 cc. each day until 50 cc. is reached on an eight-feeding day. Then give 60 cc. every three hours for seven feedings in twenty-four hours. Thereafter increase 5 cc. each day until the reauired amount is reached. Give 15 cc. water between feedings. Stomach-tube is to be passed before the feedings for the first seven or eight days after operation. Feed with medicine-dropper for first four or five days, then with the nipple. If patient is a nursing baby, put to breast on the seventh day, once for five minutes, twice on the eighth day, three times on the ninth day, and so on. Management in the Non-operative Type.—Breast milk should always be given a trial, although this usually means the securing of a wet-nurse. In large centers breast milk may sometimes be purchased, but this means 218 THE PRACTICE OF PEDIATRICS of supply is usually quite unsatisfactory. Further, breast milk is often disappointing and is often vomited as readily as other foods. We have had both failures and successes in its use. When it fails, thick gruel feed- ing (see p. 85) should at once be resorted to. In preparing the gruel mixture we find the evaporated milk gives us the best results. For an infant weighing 8 pounds with uncomplicated pylorospasm or spasm and moderate hypertrophy whose vomiting, although persistent, admits of pallative measures, we would give the following feeding directions: 7 ounces of evaporated milk. 23 ounces of water. 5 tablespoonfuls of farina. 1 tablespoonful of granulated sugar. Add the 5 tablespoonfuls of farina to the 23 ounces of water, bring to a boil, simmer for one and a half hours, then add the milk and simmer for another thirty minutes. When mixture is cool add the granulated sugar. The final mixture should not exceed 20 ounces (two-thirds the original volume), and when cold should be of the consistency of soft butter. Give 2 to 3 ounces at four-hour intervals. A Hygeia bottle and nipple may be used if an extra large opening is made in the nipple, or the food may be given with a spoon. For the first few days water should not be given between feedings. Smaller amounts of 1| to 2 ounces are given to children weighing 5 or 6 pounds. For the first day or two perhaps not more than 2 ounces are best given at a feeding. In all cases the stomach should be lavaged with a 5 per cent, sodium bicarbonate solution daily. The thick gruel feeding may be continued for several months, the milk strength, of course, being increased from time to time. Having used this thick gruel feeding in a considerable number of cases of persistent pylorospasm, we consider it by far the best means available in the management of the vomiting of infancy. Failures have occurred in cases with distinct hypertrophic stenosis, and without mechanical aid the method has been of very little value in combating rumination (p. 206). The Use of Atropin.—A solution of atropin sulphate of which 1 drop is equivalent to 1/1000 grain is commonly administered for the relief of pylorospasm in infants. The dosage should be given coincident with the four-hourly feedings and must be governed by the effects observed; 1/500 grain exceptionally produces pupillary dilatation and flushing. If no such effect is observed and the vomiting persists the dose may be increased to 4 or 5 drops of a 1 : 1000 solution, or 1/400 to 1/300 grain at four-hour intervals. Larger doses, although recommended, have sel- dom been used by us. In cases of spasm uncomplicated by true stenosis atropin is at times of value. More frequently its usual physiologic effects have been ob- served in our own cases without decisive relief of the vomiting, so that the results thus obtained have been at best indifferent. PYLOROSPASM IN OLDER CHILDREN The fact that pylorospasm in greater or less degree is of fairly frequent occurrence in children is readily demonstrable from the following case records: PYLOROSPASM IN OLDER CHILDREN 219 Figure 36 shows the stomach of a boy seven years of age in a state of active peristalsis as evidenced by the circular muscular contraction with pronounced pylorospasm three hours after injection of a bismuth meal. The boy had been ill for a week following a dissipation in ice-cream and raw fruit. There had been extreme paroxysmal pain in his stomach to such a degree that morphin hypodermically had been repeatedly necessary. It will be observed that but little bismuth had passed the pylorus three hours after the food had been taken. Figure 37 represents the stomach of a girl five years of age showing a lesser degree of pylorospasm. The radiogram was made six hours after the injection of the bismuth meal and shows very pronounced gastric retention which was repeatedly corroborated by stomach-tube examina- Fig. 36.—Pylorospasm in a boy of seven years: S, stomach; D, duodenum tion after a bismuth meal and a usual home meal. The girl was absolutely devoid of all desire for food, showed moderate malnutrition, and was habitually constipated. Enemas or laxatives were required daily. This patient was under the care of a trained nurse and did not in the least object to stomach-tube manipulation. At various times the tube was used during the night to learn the emptying time of an ordinary evening meal given at 6 o’clock. The stomach was rarely found empty before 5 a. m. the following morning. The patient had a greatly elongated and sacculated sigmoid, at least four times the normal length. Etiology.—We have proved with the aid of the x-ray two causes for pylorospasm—gastric hyperacidity and intestinal stasis. Figure 36 is taken from a case of the former, and the writer has had 220 THE PRACTICE OF PEDIATRICS other similar cases. Figure 37, taken from a case of intestinal stasis, shows evidence of sufficient spasm to produce retention. Symptoms.—Gastric irritability will cause stomach hyperstalsis and spasm, so that in the cases of those patients with elongated and sacculated sigmoids and resulting stasis the emptying time of the stomach is always delayed. There apparently is direct* association between the emptying time of the stomach and that of the large intestine. A peculiar feature of these cases of retention is loss of appetite. The patient will perhaps have a fair appetite for breakfast when the stomach is empty, but for the other meals must be forced or coaxed. The most prominent symptom of the retention cases is loss of appe- tite, and the next in order is recurrent vomiting. Fig. 37.—Female, five years. Pylorospasm, wandering stomach: Retention at four hours, showing large residue, corroborated by stomach-tube examination. Habitually poor appetite; malnutrition. D, Duodenum. Treatment.—Relief of the constipation through treatment and a long interfeeding period goes far to restore a normal desire for food as the result of more rapid emptying of the stomach. MECHANICAL DEFECTS IN THE GASTRO-INTESTINAL TRACT AS ETIO- LOGIC FACTORS IN GASTRO-INTESTINAL DISORDERS OF OLDER CHILDREN Until a fow years ago children had been given the credit of having a structurally normal gastro-intestinal tract, except in those instances in which there were gross abnormalities which involved the immediate well-being or life of the infant. Appreciation of the fact that there could PTOSIS AND DILATATION OF THE STOMACH 221 be structural defects, congenital and acquired, of a bearing of more re- mote nature was partly the outcome of the extensive studies that have been made on congenital hypertrophic pyloric stenosis. In clinical work among children suffering from persistent gastro- intestinal disorders it was found that in not a few cases the usual diagnostic methods (insp*ection, manipulation, and urine and stool examination) were not sufficient to establish a diagnosis upon which satisfactory therapy could be fashioned. Many conditions, such as the various forms of ptosis which were supposed to exist only in adult life, unquestionably have their origin in childhood, and produce as prominent symptoms in the child as in the adult. In such cases in childhood erroneous interpreta- tions or none at all have been the custom. As a result of the abnormal- ities in structure, whether congenital or acquired, producing disturbed re- lations of various portions of the gastro-intestinal tract, derangement of function due to imperfectly carried out physiologic and chemical processes within the body becomes established, the result being in many instances1 faulty nutrition, defective growth, and inferior general development of the child both physical and mental. In x-ray studies of the stomach we find dilatation and ptosis, singly or combined, hyperstalsis and hypostalsis, pylorospasm anti cardiospasm. In the intestines an elongation of the sigmoid to three or four times its normal length is the most usual deformity. With this there are the invariable angulations, sacculations, and torsions. The colon is frequently elongated, dilated in part and entire, and ptosed. Typical V-shaped ptosis (page 223) is the usual form in which this abnormality is found. Several cases of dilatation of the sigmoid have been observed which give a train of symptoms all their own. Anal sphincter spasm causing rectal constipation is a particular factor of importance in delayed stomach emptying and recurrent vomiting. The diagnosis of several cases of chronic appendicitis (page 291) has been confirmed by the x-ray. A continuation of pronounced gastro-intestinal disorders, particularly recurrent vomiting and persistent constipation with the patient under a proper living regime and right dietetic regulations, calls invariably for an x-ray study of the gastro-intestinal tract. In the pages that follow the abnormal x-ray findings will be discussed in connection with the symptomatology of the various gastro-intestinal disorders. Ptosis and Dilatation of the Stomach This combination we are finding in a considerable number of children who appearfor treatment of persistent stomach derangements. A dilated stomach, however, may not be ptosed. Roentgen ray studies of a great many stomachs lead us to believe that Fig. 38 represents the average stomach of a child four years of age, normal in size and position. Etiology.—The abnormal condition in some children is probably carried over from infancy, being the outcome of a defective pylorus, and may result from a habitual overfilling of the stomach. Children who have the milk habit, who drink large quantities of milk or water with their regular meals, are very apt to have dilated and ptosed stomachs. The carrying capacity of this organ is not unlimited and the full meal 1 Our x-ray studies now cover over 150 cases. 222 THE PRACTICE OF PEDIATRICS of solid food with a considerable amount of milk or water, produces an increase in the weight of the stomach contents, with gradually result- ing enlargement and ptosis. The fact that children who have had pylorospasm or actual stenosis in infancy and recover without operation are actually among those who have dilated and ptosed stomachs in later life has been proved by z-ray examinations of a great many personal cases, and one feature common to all is delayed emptying which has become a fixed habit. Fig. 38.—Male four years of age. Normal stomach. After the third year the stomach should normally be empty in four hours. In one patient the stomach contained residue after ten hours and did not begin to empty for two hours. This stomach required about twelve hours to empty a bismuth meal. In 6 cases the stomach contained residue after six hours. The Opaque Meal.—The opaque substance added to the food in order to give a contrast in the roentgenogram is bismuth subcarbonate, bismuth oxychlorid, or barium sulphate, especially prepared for rr-ray work. The opaque substances are usually used in the preparation of 1 part to 8 of food for a child four years of age. Symptoms.—The appetite is variable and appears to depend upon PTOSIS AND DILATATION OF THE STOMACH 223 the emptying time of the stomach. If the organ empties readily and there is an interdigestive period of one-half to one hour, the appetite is usually abnormally developed. In the event of retention of the stomach contents until the next mealtime the appetite is poor, the child has to be coaxed to eat, a vicious circle is established, and the delayed emptying helps to cause the ptosis and dilatation which, in turn, delays the emptying. It is not at all unusual for patients to show considerable stomach residue from six to ten hours after the meal. There is usually a good deal of belch- ing and sometimes regurgitation of food, and practically all children thus affected suffer from periodic vomiting seizures which are commonly Fig. 39.—Ptosis of stomach: This represents a dilated and ptosed stomach in a boy eleven years of age who exhibited a high grade of malnutrition, weighing only 52 pounds, and suffered from habitual constipation and periodic vomiting. His blood showed Hb. 72 per cent., red blood-cells 4,440,000. This boy rarely passed six weeks without a seizure, which lasted two or three days. Being a very wealthy boy he had passed through many hands and was treated uniformly for “acidosis.” In this case there was also coloptosis, the colon presenting the typical V-shaped abnormality depicted in Fig. 48. He was put under appropriate treatment and during subse- quent observation extending over a long period never had an attack of vomiting. diagnosed as “acidosis” attacks. In all the cases there is distention of the upper abdomen. Stomach pain paroxysmal in character, usually after eating, is not infrequent. Studies of the gastric contents show that there is usually a well-marked hyperacidity, and in cases in which hyper- acidity has been proved the pain or discomfort complained of occurs more often before the meal, particularly before breakfast. Practically all such children, furthermore, suffer from malnutrition; they are thin, underweight, and irritable, and in most instances show secondary anemia and have a diminished capacity for school work and play. In one significant case with emptying of the stomach delayed after 224 THE PRACTICE OF PEDIATRICS six hours there was a persistent urticaria for which condition previously the child was brought for treatment. She was nine years old and the urti- caria first appeared at the age of two years. It was largely relieved by correcting the gastroptosis. Treatment.—An important feature in the treatment of the dilated stomach whether ptosed or not is to avoid overloading the organ at any time. In order to overcome this tendency the following procedure is followed: The child is given meals with a minimum allowance of fluid Fig. 40.—This shows extreme dilatation of the stomach of a girl six years old who weighed but 29 pounds, showed a high-grade secondary anemia, and had recurrent vomiting seizures lasting from twenty-four to seventy-two hours at intervals ranging from six weeks to two months. She had been treated for “acidosis” and had always been a difficult “feeder.” The vomiting seizures began at about the eighteenth month. After the commencement of treatment there were no subsequent seizures and the child gained 13 pounds in weight in thirty months. and is made to rest on the back or preferably on the right side for an hour after the morning and midday meal of solid food. Three meals are given daily at not less than five-hour intervals. Three hours after the breakfast and midday meal 6 to 8 ounces of milk or water is given. The evening meal is given in bed with 8 ounces of fluid. The child is made to lie down immediately after. Upon awakening the following morning as much water is given as the child cares to drink, and in one-half to one hour the breakfast is served. COLIC 225 Such a regime carried out for a few months will reduce the size of the stomach if there is no pyloric obstruction. To insure further the attainment of good results children with ptosis are supplied with an Aaron band with a transverse shelf so arranged as to fit under the ptosed stomach and furnish support. To those who suffer from accumulation and eructation of gas 2-grain doses of salicin are given at mealtime or the following prescription is ordered: W Magnesise carbonatis gr. xxx Sodii bicarbonatis gr. xl Bismuthi subcarbonatis gr. lx M. div. in chart, no. xxx. Sig.—One fifteen minutes before meals, with water. In cases of dilatation due to pyloric obstruction pyloroplasty or gastro-enterostomy may be required. COLIC A brief reference to this subject has been made on p. 100. Few chil- dren complete their first year without having severe attacks of intestinal colic. In some cases the child thrives in spite of the attacks, in others such a grave degree of indigestion exists that the condition may prove most serious. The character of both human and cow’s milk, its ready decomposition in the intestine, with the formation of gas, together with the lack of development of the infant’s digestive apparatus, explain in no small degree the frequency of colic in the young. When cow’s milk is used, as in bottle feeding, we are dealing with a substance foreign to the infant’s digestive apparatus, and often colic is the outcome. Any condi- tion that will give rise to indigestion may, of course, be a cause of colic. Children who take too much milk, too strong milk, or who take milk too frequently are the usual subjects. Probably the most frequent cause of colic is indigestion of the protein of the milk. The protein may be given in excess or the child may have poor protein capacity. Not a few cases of colic are due secondarily to defective bowel action. A passage occurs each day, but in too small amount. There is a continual fecal residue in the intestine which undergoes decomposition with gas formation. Cold feet are often associated with colic. Fright, anger, fatigue, excitement—any condition, in short, which may make a sufficiently unfavorable impression upon the child’s nervous organism—may produce indigestion and colic. Likewise any adverse nervous mental state in the mother may produce colic in the breast baby. Constipation in the mother is not an infrequent cause. Infants who have colic habitually more often suffer late in the day than at any other time. Colic may be caused by an elongated sigmoid which forms angula- tions and prevents the natural passage of gas. Since making our x-ray studies of the intestinal tract we have been impressed by the frequency of stomach colic at different ages. Most of us have been under the impression that the seat of the colic was usually in the intestines. In the case now cited accumulation of gas in the stomach evidently was the cause of violent muscular contractions. This capability 226 THE PRACTICE OF PEDIATRICS of the stomach muscle-fiber under such stimulation has been emphasized by Alvery.1 Illustrative Case.—Figure 41 represents the x-ray findings in a case of most obstinate and severe colic. The patient, a girl, aged three and a half months, weighing 10 pounds, was suffering from malnutrition, extreme colic night and day, and constipation. An enema was required daily. The Roentgen ray revealed hyperperistalsis of the stomach. The sigmoid was elongated, passing 1 inch above the umbilicus, and the stomach was distended with gas. In this case the elongated sigmoid and the obstinate constipation were the cause of the stomach colic. The fluoroscope showed the stomach in active peristalsis. The colic was entirely relieved by the use of olive oil as a laxative and by the regular feeding. Fig. 41.—Female aged three and one-half months. Entire stomach outline can be made out owing to the presence of air. No bismuth present. (Roentgenogram bv Dr. L. T. LeWald.) Diagnosis.—While the diagnosis is usually a simple matter, it must be remembered that intussusception (p. 277) and appendicitis (p. 287) may cause symptoms identical with colic. Treatment.—Nursing babies who suffer from habitual colic often re- cover after the regulation of the mother’s bowels by exercise, diet, and 1 The Mechanics of the Digestive Tract, Hoeber, 1922. PREVENTION OF THE ACUTE INTESTINAL DISEASES 227 medication. In cases in which the mother’s milk upon repeated ex- amination proves too strong and the child suffers from daily colic, a dilu- tion of the milk may be made by the use of plain water or barley-water, from ounce to ounces of the diluent being given before each nursing. In addition, the bowels of the colicky infant should be made to move at least twice daily, morning and evening. When this does not take place readily a simple laxative, such as milk of magnesia, § to 1 teaspoonful, or 10 to 30 drops of aromatic cascara sagrada, may be given daily. Under no condition should a child subject to colic be allowed to go without a bowel evacuation for more than twenty-four hours. Diet.—The dietetic management of colic in the bottle fed consists in adapting the food to the child’s digestive capacity. The bottle baby may have habitual colic moderately and thrive, but is receiving an im- perfectly adapted food. Here, as in the breast fed, the condition is usually dependent upon an excessive casein supply or a diminished casein capacity. The matter of the adjustment of cow’s-milk protein in indigestion is dis- cussed in detail under Milk Adaptation (p. 66). It is sufficient to say that the colicky bottle baby should have long intervals between feedings —usually one-half hour longer than ordinarily allowed. Digestion is slow in many of these infants, although in other respects they may be healthy children. In some the indigestion and pain are so severe that a perfect adaptation of cow’s milk is impossible, and some other food than cow’s milk will be required. The prevention of colic, then, rests upon a proper adjustment of the food. Enemas.—The immediate attack is usually best relieved by the use of an enema at 110° F. of a normal salt solution, or of soapsuds, which, by inducing a movement of the bowels, allows the gas to escape. Medication.—A soda-mint tablet dissolved in 1 ounce of hot water given in 1-teaspoonful dose repeated at five-minute intervals is some- times efficacious. For a child under one year of age 3 drops of spiritus setheris compositus (Hoffmann’s anodyne) may be given in 2 teaspoonfuls of hot water and repeated at ten-minute intervals. Hot applications to the abdomen are often gratefid to the patient. For this purpose 10 drops of turpentine in 1 quart of water at 120° F. may be Used with benefit. A flannel is wrung out of this turpentine solution and applied over the abdomen and covered with a dry piece of flannel. The dressing may be changed every ten or fifteen minutes. Opium and its derivatives should not be used in the treatment of colic. This drug may relieve the pain temporarily, but it aggravates the condition to which the colic is due. PREVENTION OF THE ACUTE INTESTINAL DISEASES The general topic of disease prevention has been touched upon in an earlier chapter (p. 133). The acute intestinal diseases of summer, with their large infant mortality, offer a better field for life-saving measures than does any other group. Potent etiologic factors contributing to summer diarrhea are unfavor- able climate and unfavorable environment. In dealing with the class which furnishes the largest mortality, climate cannot be changed for a sufficient number to exert any great influence on the general mortality. Through 228 THE PRACTICE OF PEDIATRICS education the environment may be radically improved, but it cannot be changed. The hot months come and the tenement child must remain at home. Excursions and outings of various kinds are valuable in a small way to comparatively few, as the child must return to the tenement home at night or after a few days’ absence, so that in our consideration of this class of patients in large cities we must accept unfavorable environment and hot weather—in other words, we must treat these cases in their homes. Those more fortunately situated, who can have the advantage of the country and intelligent care, are proportionately less liable to diar- rheal diseases. Other than climate and environment, the determining etiologic factors among all classes are: first, a disordered gastro-enteric tract; second, infected food; third, faulty feeding methods; fourth, an absence of appreciation on the part of the parents and physicians of the fact that an attack of diarrhea or vomiting, or even a single green, undigested stool, occurring in an infant under eighteen months of age during hot weather, is to be looked upon as a serious matter requiring prompt attention. Children as well as adults are frequently exposed to disease from sources of which they are ignorant, because their power of resistance is insufficient for their protection. With milk, the most readily infected of all nutritional substances, as the chief article of diet, it may safely be assumed that few infants will pass through the heated term without being subjected repeatedly to infection from bacteria, sufficient to produce grave illness. An infant’s best safeguard against intestinal infection is a strongly resistant gut. Feeding and intelligent management generally throughout the year has, consequently, a decided bearing upon summer mortality from intestinal diseases. We have abundant opportunity to observe that the children who have frequent attacks of intestinal indigestion during the colder months furnish our severe cases during the summer. A most important feature, then, in prophylaxis is to teach the mother how to feed and care for the child all the year round, in order that, by keeping well, the child may maintain a high grade of intestinal resistance. Dispensary Rules of Universal Application.—At the Out-patient De- partments of the Babies’ Hospital and the New York Polyclinic the senior author had abundant opportunity to come into close contact with a great many tenement mothers and tenement children. At these institu- tions the clientele is fairly regular in attendance, year after year; for as one baby after another appears in the family, each is brought for treat- ment. At these dispensaries there is a surprisingly low summer diarrhea mortality, because the mothers are taught how to feed and care for their children all the year round. They are taught the value of fresh air, the use of boiled water as a beverage, and the benefits of frequent spongings on hot days. Both private patients and dispensary mothers have been given pamphlets of instruction and also oral teaching bearing on these points, and particularly those relating to the care of the feeding bottle and the milk. In case special articles of diet are to be given, the mothers are taught how to prepare them. Written directions are always given covering the point; nothing is left to the memory. Each mother and nurse has it impressed upon her that she must wash her hands in soap PREVENTION OF THE ACUTE INTESTINAL DISEASES 229 and water before touching the baby’s food or feeding apparatus for any purpose, and that there must be a covered vessel in which the soiled napkins are to be kept until washed. At the first sign of intestinal de- rangement, regardless of the season of the year, they are taught to stop the milk at once, to give instead a cereal water, such as barley-water or rice-water, and a dose of castor oil. It is impressed upon them that, in winter as well as summer, a green, watery stool means that the baby is ill and needs treatment. When the mother learns the above lesson for December, January, and March, she will not forget it in July. Further- more, as a result of the immediate correction of a child’s digestive disorder during the winter months, the digestive tract affords a much less fertile field for pathogenic bacteria during the summer. Prompt Treatment Essential.—Comparatively few cases of intestinal diseases have pronounced toxic symptoms at the outset. At first there are evidences of a milk infection only. There may be vomiting, several green, watery stools, and a slight elevation of temperature, or the signs may comprise only one or two loose green defecations. Prompt treat- ment at this time, even in a crowded tenement, usually means prompt recovery. When treatment is delayed and the administration of milk is continued, severe toxic symptoms and intestinal lesions are almost in- variably the result. New York City Experiments.—An interesting demonstration of what may be accomplished by proper care was made under the direc- tion of Dr. William H. Park, of the New York Health Department, during the summer season. Fifty tenement children, ranging from three to nine months of age, were selected for the experiment. These children were all fed on the Straus pasteurized milk and were visited two or three times a week by physicians especially assigned to them. The mothers were carefully instructed as to the care of the milk and the feeding appa- ratus, and in other necessary details. With the first signs of illness the milk was to be stopped, the physician notified, and suitable treatment instituted. Among these 50 tenement children, all under one year of age, all bottle fed, selected at random, there was not one death during the summer. This valuable observation bears out the contention that the deaths from summer diarrhea among tenement children may be greatly reduced by the use of good milk given under proper supervision, supple- mented by prompt and competent medical care at the first sign of illness. Perhaps in 1 per cent, of the cases of summer diarrhea a very severe direct infection is evident, and the condition of the patient is very grave from the onset. In the remainder the invasion is gradual; and, if the warnings are heeded, the illness will usually terminate quickly in recovery. How to Secure Good Milk.—To patients of the better class who go to the country for the summer, and who have cows of their own in order to con- trol their milk-supply, the following directions have been given: Before milking, the udders and belly of the cow should be wiped with a damp cloth to remove clinging particles of dirt. It is in these droppings containing manure that the most dangerous forms of bacteria of decomposition enter the milk. The milker should wash his hands before milking. The first few jets of milk, coming from the ducts near the openings, are apt to be swarming with bacteria, and are, therefore, to be dis- carded. Immediately after the milking the milk should be strained through several thicknesses of cheese-cloth, or through absorbent cotton, into an ordinary milk bottle, which is at once placed in a pail of cracked ice. 230 THE PRACTICE OF PEDIATRICS Such simple care as this, even on an ordinary farm, gives a very low bacteria count. As may readily be seen, it is attended with very little trouble and expense. The Necessity for Education.—The suggestions we have offered are all included under the one general heading of Education. The mother must be educated how to live, how to care for the baby, how to clothe and bathe him during the summer. It must be impressed upon her that he needs all the fresh air available. She must be educated to the point of knowing what to do at the first sign of threatened disease. Municipal- ities must be educated to appreciate their responsibility as factors, nega- tive or positive, in the summer mortality. The farmer must be educated to produce safe milk, and the consumer must be educated to appreciate its value and pay for it. Above all others, the physician must be educated along these lines so as to be able to teach the mothers how to do right in the care of their children the year round. ACUTE INTESTINAL INDIGESTION This disorder is referred to first because, according to our observa- tion, of all the intestinal disorders, it is the most frequently seen. Be- cause its importance is not recognized the prophylaxis and treatment receive but little consideration. The proper appreciation and manage- ment of a disordered intestinal function are essential to the solution of that most important problem—summer mortality from diarrheal diseases. As pointed out elsewhere, the most fertile field for later dis- ease is furnished by the intestine which is persistently deranged. In June the mortality from acute intestinal disease in Greater New York in children under two years of age has repeatedly been but 300 to 500 less than in August. The high June mortality has been explained by the fact that the list included many cases of malnutrition and maras- mus, but it must be remembered that the list includes also cases of infants with diminished intestinal resistance, who are ready victims to the al- most invariable exposure, through infected food, to which every bottle- fed infant is subjected at some time during the summer, when heat and humidity aid in lowering the general vitality. A close investigation of hundreds of cases of severe acute intestinal disorders of infants has shown that a great majority are not so acute as a superficial history would indi- cate. A complete history in a case of acute gastro-enteric intoxication (cholera infantum), or in one of apparently severe intestinal infection with resulting colitis, or one of acute colitis (dysentery), will show that the child had defective intestinal digestion during the previous cold months, and that the grave condition which he presented when brought for treat- ment had been preceded for two or three or more days by simple diar- rhea, probably without vomiting and with little fever. The fact that the patient did have green passages and did have diarrhea indicates the existence of intestinal indigestion before the urgent symptoms of fever and prostration developed. In only about 1 per cent, of the cases of severe gastro-enteric diseases of children in summer the onset is sudden without warning, and with urgent symptoms. Symptoms.—Fever is usually present in varying degree. It may be PERSISTENT INTESTINAL INDIGESTION 231 as high as 104° or 105° F. Restlessness, abdominal pain, and moderate prostration are usual symptoms. The stools are frequent, undigested, green, and may contain mucus. Duration.—Properly managed, the case has but a few days’ dura- tion. The temperature readily subsides, and the child soon shows evi- dence of displeasure at the reduced diet. Prognosis.—The condition is serious only in the sense that it may be the starting-point of severe intestinal intoxication. Properly treated cases present few dangers. Treatment.—The time to treat these cases of intestinal indigestion, in order to secure most effective prevention of severe toxemia and grave lesions, is before the physician sees the patient. The reduction in the mortality rests in the education of the mother to the point of realizing that a loose green stool is a danger signal. When it occurs, she is to give a dose of castor oil (2 teaspoonfuls), stop the bottle or stop the nursing, and give the baby boiled water or barley-water until the physician can see the patient. Every mother should at the beginning of warm weather be instructed in proper summer care of the infant. The Breast Fed.—Intestinal disease of severity in infants fed entirely on breast milk is exceedingly rare. With a breast-fed baby it may be necessary to discontinue nursing for from twelve to thirty-six hours, to give 1 or 2 drams of castor oil, and to substitute for breast milk barley-water or rice-water No. 1 (see p. 94), to each pint of which or J ounce of cane-sugar is added. While nursing is discontinued the breasts should be pumped at the regular nursing hour so as to keep up the flow of milk and relieve tension. Rarely will other treatment be required. The Bottle Fed.—With the bottle fed greater caution will be necessary. The management consists in continuing the carbohydrate diet, which the properly informed mother has instituted, until the stools approximate the normal. This may necessitate an abstinence from milk for three or four days, by which time it may usually be resumed. The milk should always be given in reduced quantities for the succeeding day. One- half ounce of skimmed milk may be added to every second feeding or to every feeding of the gruel. If it is well digested and causes no return of the diarrhea, the amount of milk may be increased tentatively every day or two by the addition of \ ounce to each feeding. In some of these cases the diarrhea without fever will continue. In such instances the administration of 10 grains of bismuth subnitrate with \ to \ grain of Dover’s powder at two- to three-hour intervals, aids materially in establishing the normal intestinal function. PERSISTENT INTESTINAL INDIGESTION The special part of this subject, which has been covered in the con- sideration of the management of malnutrition and marasmus, is again referred to here in order to call attention to those conditions which, though mild in character, constitute so important an etiologic factor in the acute intestinal diseases of summer. We have learned that a considerable part of the summer mortality of acute intestinal diseases occurs in children who have a reduced intestinal resistance as a result of 232 THE PRACTICE OF PEDIATRICS peristent intestinal indigestion, although this may not have been suffi- cient to have interfered appreciably with nutrition. A considerable number of infants do not have a normal bowel evac- uation even for two days out of ten. There is constipation, which is neglected, or there is passage of undigested or loose stools. In some cases constipation alternates with diarrhea. Occasionally there is a sharp attack of diarrhea with fever. In getting the history of our cases, regardless of the nature of the illness, we often learn that the infants have undigested stools. There is a tendency to an unstable intestinal equilibrium. This condition of intestinal indigestion is ordinarily due to errors in diet involving the habitual giving of unsuitable articles of food, or of food too strong, or feeding at too short intervals. Treatment.—The management of each case is determined by the age of the patient and the conditions of the family, and is discussed in the sections relating to Nutrition, Substitute Feeding, and Modification and Adaptation of Foods. In some instances the intestinal indigestion is the result of anatomic defects or malformations in the gastro-intestinal canal. In this condition there is disturbance of function and there may be sufficient absorption of toxins from the intestinal canal to produce a wide range of symptoms. Whether this causes pathologic conditions in other organs it is often not possible to state. One may assume, however, that such is the result. Comparatively little attention appears to have been given the subject. There is no doubt whatever concerning its etiologic importance in the nutritional and so-called functional nervous disorders of childhood. One reason why little attention has been called to the intestinal tract as an etiologic factor is perhaps because the child is not necessarily constipated. Intestinal toxemia may exist with one or two apparently normal passages daily, and even without the presence of indican in the urine. Pain is not a necessary symptom. It is occasionally present, how- ever, as is also abdominal discomfort involving a sensation of constriction and pressure. The conditions in wThich intestinal toxemia has seemed to play a part sufficient to form a symptom complex have been habitual headache, disorders of speech, choreic in character, secondary anemia, habitual sleep talking, sleep walking, teeth grinding, and general irritability without apparent cause. Well children are naturally bright and happy. When a child is persistently cross and irritable he is not a well child. Chronic papular eczema has proved to be of intestinal origin in a con- siderable number of cases, particularly among the out-patient class. The condition often regarded and treated as malaria is not infrequently due to intestinal toxemia, as fever of a degree or two may be present for protracted periods, leading the physician to give at some time or other a course of quinin. Such a patient is very apt to be habitually tired and languid, and although he may be fairly bright early in the day, in the afternoon he yawns and complains of being tired and sleepy. The blood examination fails to reveal signs of malarial infection, and quinin in full Persistent Intestinal Indigestion in Older Children PERSISTENT INTESTINAL INDIGESTION 233 doses furnishes no relief. The appetite may be fairly normal, the tongue may show no signs of digestive disorder, although such is rarely the case. The tongue is usually coated and the appetite capricious. The symp- tom complex which suggests to the mother the thought of worms is usually the manifestation of intestinal toxemia. An important feature of these cases is the continuous elevation of the temperature a degree or more daily. In not a few instances the case is proved to be one of a low type of toxemia due to milk incapacity. Illustrative Cases.—A boy, aged three years, highly nervous and irritable, was afflicted with day terrors—pavor diurnus. The attention of the nurse was attracted to the condition when he asked that the “bugs” be removed from his lap-robe when he was in his go-cart. The time was midwinter, and there were no bugs present. On one of these occasions when asked to pick up a bug, he tried to do this with his fingers and could not understand why he could not catch them. His tongue was heavily coated and he had required a laxative every third day. There was an excess of indican in the urine. He was taking a large amount of rich cow’s milk daily. After stopping this, a full dose of rhubarb and soda was given daily and he was well in a week. A boy five years old was brought for examination because of disturbance of speech. He had been normal until three and a half years of age, when he had difficulty in the formation of entire words. This had increased with the development of other nervous phenomena. There was marked inco-ordination in speech—dysarthria—due to choreic movements evidently of the tongue and laryngeal muscles. The boy was exceptionally well nourished and there was an absence of choreic movements in other parts of the body. The knee reflexes wTere considerably increased. He was easily excited. Hard play was followed by restless nights, and he talked in his sleep every night, regardless of the habits of the day. Inquiry into the diet failed to reveal any grave errors. He drank 1 quart of milk daily, although milk had never agreed with him as an infant. The bowels moved once daily. The movements were often of foul odor, and the mother stated that she was satisfied they were too small. The patient after three weeks showed striking improvement on a diet without milk, with a daily laxative, and made a com- plete recovery in three months. A third patient was a girl six years of age who lived in the best surroundings, in a country district. She was pale, rather thin, and below weight for her age. She had been chronically tired and irritable for two years. The blood showred the existence of a secondary anemia, and the urine contained a marked excess of indican. She had been taking quantities of quinin. Her appetite was indifferent, but she had no con- stipation. She favored milk and was paid for drinking extra quantities to the amount of about 2 quarts daily. Marked improvement followed the withdrawal of milk from the diet and the use of laxatives. Treatment.—In our experience the management of these cases which has been most successful has consisted in the discontinuance of cow’s milk, with the further dietetic restriction to but one egg every second day, and flesh food but once daily. Cereals, fruit, and vegetables may be taken as suggested in the dietary (p. 135). The use of green vegetables is particularly to be encouraged. In place of cow’s milk malted milk may be given, and to facilitate the bowel action a raw apple may be given in the middle of the afternoon. The patient should take an after dinner rest for an hour or two. If constipation is obstinate, rhubarb and soda of the following strength are recommended: 1$. Pulveris rhei gr. iv Sodii bicarbonatis gr. viij Syrupi rhei aromatici 3ss Aquae q. s. ad. 3j M. Sig.—One teaspoonful once or twice daily. If the patient can take a capsule the following is preferable for a child from five to eight years of age: 234 THE PRACTICE OF PEDIATRICS lb Tincturse belladonna} gtt. ij Tinctura} nucis vomicae gtt. iv Extracti cascarae sagradae gr. i-iij Sodii bicarbonatis gr. iij M. ft. capsula No. i. Sig.—To be taken at bedtime. The medication may be continued for three or four weeks, after which time 1 dram of the syrup of the hypophosphites (Gardner’s) may be given three times a day. This may be alternated with: 3. Ferri et ammonii citratis gr. xxiv Elix. simplicis 3j Aqua? q. s. ad. 3iv M. Sig.—One teaspoonful three times daily after meals. In the event of constipation persisting after the use of the laxative, the oil treatment (p. 273) may be brought into use and continued until the condition is relieved. The gastrointestinal tract is exposed, of necessity, to influences from without which may exert decided effects upon the physiologic processes of its different parts. It is obvious that there may be lesions in any part of its structure, and that such lesions may cause a derangement of function, if not actual disease, by transfer of infection to other parts of the tract. Thus there may be lesions, single or multiple, in various portions of the gastro-intestinal tract. There may be a simple gastritis, or an ileitis or colitis singly or in combination, entirely independent of pathologic conditions of the other portions of the tract. The function of the gastro-intestinal tract is the final preparation of food substances for the use of the organism. These food substances are perishable in character and susceptible to bacterial influences and chem- ical change. Obviously, this long tube, adapted for absorption and of an anatomic and physiologic construction of most intricate and sensitive nature, offers ready fields for bacterial invasion and chemical change, and consequently is subjected to constant insult by toxic agents result- ing from bacterial and chemical processes. For the past two hundred years investigators have attempted a classi- fication of the acute gastro-intestinal disorders, and while much progress has been made in framing a classification sufficient for bedside and teach- ing purposes, let no one imagine that the last word has been said. With an increase in knowledge of the subject, old theories and concepts will be disproved and new theories evolved which may share the fate of their predecessors. It is not wise to be carried away by the theories of our time concerning a subject the etiology of which is based upon so many factors, not the least important of which is that of physiologic chemistry, a subject of which we can boast too little absolute knowledge. Until we possess demonstrable facts it is best in teaching not to go into vague chemical and metabolic theories. Symptoms.—This form of intoxication, while acute in character, is rarely of primary origin. It is usually preceded by disordered gastro- enteric digestion. The onset is sudden, with pronounced prostration, persistent vomit- ACUTE GASTRO-ENTERIC INTOXICATION ACUTE GASTROENTERIC INTOXICATION 235 ing, retching, and the passage of large, watery stools of greenish color. The pulse is soft and rapid. In a few hours the prostration becomes extreme, the respiration quick and shallow, the eyes sunken, and the skin dry and ashen in color. The extremities are cold; thirst is intense. The fontanel is depressed. The anus becomes relaxed, and often there is a constant slight discharge of the intestinal contents. The temperature is variable and inconstant—it may be high, 105° to 106° F., or it may never arise above the normal. The lower tem- perature cases with repeated vomiting and profuse diarrhea are the most hopeless. The system is so overwhelmed by the poisoning that a reaction is impossible. As the disease progresses toward a fatal termination the patient develops stupor and occasionally convulsions. Coma rapidly ensues, and death from a virulent poisoning process is the outcome. An infant may die in twelve hours from the onset of the symptoms. The loss of weight is most rapid. In twenty hours a nine-month- old baby lost 2 pounds. The loss of a pound or more in twenty-four hours is not at all unusual. Illustrative Cases.—At the Nursery and Child’s Hospital a child fifteen months of age was taken acutely ill with vomiting and diarrhea at 11 o’clock in the morning. The child was seen by the house physician, and suitable management was instituted. On rounds at 4 o’clock the child was found moribund in spite of active treatment, and death took place six hours later. Thirty-one children in this institution were poisoned by a can of stale milk left by a dealer who was short of a sufficient fresh supply. Thirteen deaths in children under eighteen months were traceable to this can of milk. Not all cases are as severe as the foregoing descriptions represent. There are cases in which there is a sharp rise in temperature to 105° or 106° F., with active vomiting and profuse watery stools. The fever soon subsides. The stomach is washed, milk is withheld, boiled water, weak barley-water, or rice-water No. 1 (see formula, p. 94) is given, and the child is well in a few days. In the more severe cases that re- cover several weeks elapse before the patient regains normal vigor. The urine contains albumin, and usually a few hyaline and epithelial casts—findings that are common in all severe acute toxic processes, and have no significant bearing upon the illness. Infants ill with intestinal intoxication not infrequently develop severe acidosis. In such cases the prostration is extreme. There is rapid breath- ing—evidence of air hunger without cyanosis or respiratory obstruction, and with the chest signs negative. Coma early supervenes and the out- come is usually fatal. Pathology.—The postmortem findings are negligible. The stom- ach and intestines present a very pale, washed-out appearance. The intestine usually contains a mucoid, yellowish substance entirely free from fecal odor. The brain may show a cerebral anemia; more often there is moderate edema of the meninges—the so-called wet brain. Treatment.—The management of the case depends entirely upon the nature and urgency of the symptoms. In the acute choleraic or so- called cholera infantum cases, with repeated vomiting, severe toxemia, retching, and profuse watery stools, stomach washing and bowel irri- 236 THE PRACTICE OF PEDIATRICS nations are useless procedures. We must support the patient and aid him to bear the infection with which he has to contend. If the temperature is high and the skin dry and hot, a cool pack to the trunk, at 85° to 90° F., subsequently moistened with water at this temperature every half-hour, will often control the pyrexia. If the feet are cold, hot-water bottles should be brought into use. If the temper- ature is below normal and the peripheral circulation poor, as indicated by a leaden hue of the skin, a hot-water bath at 108° F. for five minutes will always be of service. The bath may be repeated at half-hour intervals. In addition, the immediate treatment calls for hypodermic stimulation and sedatives. The administration by mouth of food or stimulants should not be attempted. Tincture of strophanthus and brandy, hypoder- mically, have served well in these cases. Twenty drops of brandy with 2 drops of the tincture of strophanthus may be given at intervals of one, two, three, or four hours, depending upon the urgency of the case. A combination of morphin and atropin may be used in cases with persistent vomiting, with a view to controlling the attempts at vomiting which exhaust the patient, and also to diminish the continuous loss of the fluids of the body from the repeated large, watery stools. Obviously, morphin should not be given unless this condition exists. For a child one year of age 1/50 grain of morphin may be given with 1/500 grain atropin, and repeated as required, not oftener than once in two hours. After the first year 1/30 grain of morphin may be given as an initial dose. Bene- ficial effects from the morphin will be noted in a diminution in the number of stools and the frequency of the vomiting. In milder cases of infection in which the vomiting and defecation are less frequent, a different course is to be pursued. In these cases abstin- ence from food must be enforced, boiled water being given if the child can retain it. If vomiting persists, the water should be discontinued. The stomach should be washed at least once daily and the colon ir- rigated. If the irrigation brings away mucus and fecal matter, it should be repeated at intervals of from eight to twelve hours. The child should never be disturbed for this purpose if the intestine continues to empty itself at frequent intervals. A reduction in the temperature, cessation of the vomiting, and a dim- inution in the number and improvement in the character of the stools, tell us whether or not the case is doing well and determine the further treatment, after the initial dose of castor oil or calomel has been given. As a rule, the milder type of case does better when calomel is used. If there is a tendency to vomit, the oil will rarely be retained, regardless of how it is given. From 1/15 to 1/10 grain of calomel may be given at fifteen-minute intervals until 1 grain is given. While slower in its action, it is ultimately of more benefit than the oil, which is apt to be re- jected. Feeding During the Attack.—When the vomiting has subsided, tea- spoonful doses of plain water, bicarbonate of soda solution, barley-water, Granum-water, or rice-water, should be given at fifteen-minute or half- hour intervals, and the amount should be increased in quantity and be given less frequently as the case improves. It is well, in using milk ACUTE GASTROENTERIC INTOXICATION 237 substitutes, such as cereal waters, to use alternately, for the sake of variety, three or four different preparations. The child will not then so soon tire of the milk substitute as when but one is given, and will thus take more food. It is extremely rare that the substitutes barley, rice, or Granum will not be taken if used in this way, particularly if they are made more palatable by the addition of salt and sugar or saccharin. In cases showing signs of acidosis, which is indicated particularly by deep and labored breathing, bicarbonate of soda should be given at once, 10 grains every hour if possible, until the patient receives at least 120 grains in twenty-four hours. It is to these urgent cases that not only bicarbonate of soda but glucose should be given intravenously (p. 772). Intraperitoneal saline injections and even transfusion should be employed in extreme cases. Drugs.—Unusual care must be exercised in the use of astringent drugs in the cases we are discussing, particularly in cases that are mild or moderately severe. It is to be remembered that it is in the intestinal contents that the trouble exists, and not in the intestinal structure, and that the diarrhea is a conservative attempt on the part of nature to pro- tect the intestinal structure. Our first efforts, therefore, should not be directed toward stopping the diarrhea, but toward assisting in the elim- ination of the intestinal contents productive of the illness. The indis- criminate use of opium and astringents may do irreparable damage in a very short time through a locking up of the intestine, which may be followed by a sudden rise in temperature, convulsions, coma, and death. When there is tenesmus, with frequent large, watery stools, opium may be given with caution in small doses sufficient to control the number and character of the stools, with a view to prevention of an excessive loss of fluids from the body. This drug should never be given when there are only four or five free evacuations in twenty-four hours, associated with more or less fever, as in such cases this number is required to maintain proper drainage. The opium should further be given independently of other medication, so that its use may be stopped when the excessive number of stools ceases, or in the event of a rise in temperature after it has been given. It would not be desirable, perhaps, to discontinue the bismuth or other drugs which may have formed a part of the prescription. Dover’s powder, \ to § grain, given at intervals of two or three hours is suitable for a child from six to eighteen months of age. Bismuth sub- nitrate in not less than 10-grain doses at two-hour intervals has given most satisfactory results. In order to be of service it must produce black stools. In other words, if the bismuth is not converted into the sulphid in the intestine, it apparently is of no service, i. e., if it passes through the bowel unchanged, no favorable influence will be exerted on the in- testine. This lack of effect is observed in a small percentage of cases. In such an event the necessary amount of sulphur may be supplied by the use of sublimated sulphur, 1 grain being added to each dose of the bismuth. A convenient and agreeable way of giving the bismuth is the following: W Bismuthi subnitratis 3v Syrupi rhei aromatici 3i>j Aquse ' q. s. ad. 5 iv M. Sig.—One teaspoonful every two hours. 238 THE PRACTICE OF PEDIATRICS If sulphur is necessary, a 1-grain powder may be added to each dose of the bismuth mixture at the time of its administration. In the same way Dover’s powder, if opium is indicated, may be dropped into the bismuth mixture. The bismuth is to be continued in the large doses until the child is ready for milk, when the dose should be diminished one- half and continued until full milk feeding is permissible, or until consti- pation contraindicates this drug. In using the bismuth in the large doses advised it is necessary that the chemically pure drug be obtained. If free nitric acid or arsenic is present, as is the case in some of the com- merical bismuth on the market, vomiting may result, or symptoms of arsenical poisoning may develop. Irrigation of the colon (p. 854) may be used when there is a tendency to bowel inactivity with high tem- perature. If there are loose watery passages, irrigation is not called for. Hypodermoclysis, Intraperitoneal and Intravenous Infusions.—The injection of warm normal salt solution into the subcutaneous cellular structure of the body is frequently advocated by pediatric writers for the very urgent cases in which there is extreme prostration and rapid loss in weight due to the persistent watery discharges. We have employed this treatment in a great many cases, but rarely have found it of great utility. In the cases where such addition of the fluid is most needed, it may not be absorbed because of the lowered vitality of the patient, while those whose tissues are able to take up the salt solution frequently do well without it. The more direct methods of intravenous glucose administration and intraperitoneal injection of saline (p. 850) are now supplanting the older procedure of hypodermoclysis, although their indorsement has been by no means universal. Diet.—A difficult problem of no little importance is the nutrition of the patient after the acute symptoms have subsided. When the tem- perature has been normal for two or three days, and the character of the stools improves to such a degree that freer feeding than carbohydrate decoctions is to be thought of, unusual care is necessary in order to avoid a reinfection. Skimmed Milk.—It must, of course, be our effort to resume milk feeding as early as possible, but in resuming milk the amount given must be increased very gradually—at first only \ to \ ounce of skimmed milk being given in every second feeding of the cereal gruel. In not a few cases even these small amounts will result in a rise of temperature and a return of the diarrhea. There are always pathogenic bacteria remaining in the intestinal tract after an illness of this nature, which, under the influence of such a favorable culture-medium as milk, take on renewed activity. The whole illness may, therefore, be repeated perhaps with greater severity than the original one if the milk feeding is persisted in. One repeatedly sees infants who are having what is called a relapse. What they have is a reinfection, with all the symptoms as severe as, or more severe than, those of the first infection, because of a lack of appreciation of the necessity of great care in resuming milk. To avoid mistakes in feeding at this time, as well as early in the disease, all directions should be carefully written. Nurses and mothers who think the physician is overcautious and pity the hungry child are very apt to forget oral instructions and give more milk than is ordered. If the ACUTE GASTROENTERIC INTOXICATION 239 small amount of milk agrees, it may gradually be increased by the addition of \ ounce to each feeding every two or three days. Rarely, however, will it be possible or wise to attempt to give, for the remainder of the summer, as strong a food as was taken before the illness. In milk feeding at this time a high fat content must not be used. Either full milk or skimmed milk, properly diluted, should be given. If there is a tendency to relaxation of the bowels, with frequent passages, the use of skimmed milk is indicated. Whether the milk shall be pasteurized, sterilized, or raw depends upon the conditions referred to under Sterilization and Pasteurization (p. 63). The Wet-nurse.—Not a few marasmic out-patients belong to the class who, after an attack of diarrhea, cannot take even as small an amount of cow’s milk as | ounce in each feeding. After a sharp intestinal in- fection, if the baby shows inability to take a nutritious diet, a wet-nurse may be secured for the well-to-do, but the wet-nurse’s milk will not always agree. Children who have been very ill with any of the severe forms of acute intestinal disease of summer have, as a result, a very weak fat capacity, and the wet-nurse’s milk, which perhaps contains 3 or 4 per cent, of fat, may produce diarrhea sufficient to require its discontinuance. When employing the wet-nurse in such cases it is accordingly best never to permit the child to have the full allowance of breast milk at first. To an infant from three to six months of age, for example, it is well to give 2 or 3 ounces of barley-water or a 5 per cent, milk-sugar-water before each nursing, so that the patient will be satisfied with 2 or 3 ounces of the breast milk. When cow’s milk cannot be given and the nurse’s milk does not agree, or where for any reason a wet-nurse is not possible, we are called upon to furnish other means of nutrition, and this, with our available resources, will not be of a very high order for infants under one year of age. Animal Broths.—The animal broths are of very little service. They contain but little nourishment even if given in considerable quantity and may produce a decided laxative effect during convalescence from diarrhea. They are of value only in small quantities of an ounce or two added to the gruel to make it more palatable. Cereal Decoctions.—Strong starch foods cannot be digested in suffi- cient amount to maintain the nutrition. Dextrinizing processes are therefore of considerable service. The starch is thus converted into maltose, which is readily assimilable. With this, as with the broth, the relaxing effect of the food on the intestine may be felt, frequent bowel evacuations being a possible result. The dextrinized gruels, however, are always worthy of trial, and they have been of considerable service as a substitute for cow’s milk. Condensed and Evaporated Milk.—When breast milk is not available, condensed milk usually answers better than any other food, being much more easy of digestion than fresh cow’s milk. The condensed milk at first is to be added in small quantities to the cereal water made from barley, rice, or Granum, No. 1 strength being employed. (See Formulary p. 94.) One-half dram may be added to every second feeding for the first day, and on the following day this amount may be added to every feeding. The condensed milk usually will be well taken and well di- 240 TIIE PRACTICE OF PEDIATRICS gested. It should be gradually increased until 2, 3, or 4 drams are added to each feeding. When it seems desirable to use more than 2 drams at each feeding, unsweetened evaporated milk, if obtainable, furnishes an increased amount of protein and fat without the excessive percentage of sugar. In not a few cases the combination of evaporated milk and cereal diluent must furnish the nourishment for the remainder of the heated term. With the advent of cooler weather, 1 ounce of weak raw milk with the cereal diluent may be substituted for one of the regular feed- ings, and later this may gradually be increased \ or 1 ounce at a time until the raw milk comprises one-third of the food mixture. When this point is reached, an attempt may be made to replace with raw milk another feeding of the evaporated milk. In this way, by carefully watching the case, a gradual replacing of the evaporated milk by fresh raw milk feeding may successfully be brought about until raw milk only is given. Feedings After the First Year.—After the first year similar methods may be followed if necessary, although at this age plain milk will usually be tolerated earlier, and other means of feeding than the milk may be brought into use. Zwieback, bread crusts, and scraped beef—2 or 3 teaspoonfuls a day—will often be taken without inconvenience when milk in sufficient amount for proper nutrition disagrees. At this age the gruels also may be made stronger. No. 2 or No. 3 (see Formulary, p. 94) will often be well borne. An important point to be remembered in feeding convalescents from an acute gastro-enteric disorder is that the food must not be forced, and that the child must be fed only in ac- cordance with his digestive capacity. This can best be determined by watching the temperature and the stools. The gruels as substitute foods, whether alone or combined with condensed milk, may be given in quan- tities equal to those which the child was accustomed to take in health, and they may be given at more frequent intervals, never, however, oftener than every two hours. A child who has been fed at four-hour intervals may take the substitute at three-hour intervals. If fed at three-hour intervals, he may receive the substitute at two- or two-and-one-half-hour intervals. When constipation follows a sharp attack of diarrhea, an enema may be used not oftener than once in twenty-four hours. The patient should not be given a laxative for several days after the acute symptoms have subsided unless there is fever. Protein Milk.—For young infants—under nine months or thereabouts —protein milk (p. 88) may sometimes be used with good effect. The taste, however, is not agreeable to older children, many of whom refuse it. In such instances saccharin may be used for sweetening purposes. At first, after the acilte symptoms have subsided, the protein milk is to be given with barley-water, 1 part of the milk to 3 parts of barley- water. This may be rapidly increased to equal parts of protein milk and barley-water. It is not wise in most instances to give the milk stronger than this dilution. The protein milk is often retained and digested more readily than cow’s milk, may be given in larger daily amounts, and is a valuable means of sustaining the child for a few days or a week until cow’s milk or condensed milk (p. 78) may be tolerated. Termination.—The termination of acute gastro-intestinal intoxica- tion is in death, prompt recovery, or in the development of ileocolitis. ACUTE ENTERIC INTOXICATION 241 The transition to an ileocolitis in some cases is so sudden that its exist- ence from the onset is often assumed. That such is not the case is proved by autopsy experience in hospital and institution work, with cases dying in a day or two from toxemia, in which no intestinal lesions of conse- quence are found. The continuation of fever and diarrhea, with loose green mucous stools, means that an ileocolitis has developed as a result of the toxic agents in the intestine. Acute Enteric Intoxication This type of intoxication differs clinically from the foregoing in that there is no vomiting and rarely fever. Any elevation of temperature occurring is usually no more than a sharp rise to 105° or 106° F., and is of very temporary duration. In the great majority of the cases there is no such elevation, and more often during the entire course the tem- perature is subnormal. The presence of moderate fever is a favorable sign, and indicates a more favorable prognosis. The clinical picture is similar to that of a case of gastro-enteric intoxication in that the prostration is extreme, the extremities are cold, the eyes sunken, the fontanel depressed, and the features drawn and pinched. Convulsions and muscular twitch- ings are often present. The mental condition is dulled, and the child lies in a semistupor, offering little or no resistance when disturbed. Diar- rhea may be severe, or there may be constipation, with or without tym- panites. In some cases there is an intestinal paralysis sufficient to resist all attempts at an evacuation. In such instances death may occur in twenty-lour hours from the onset without a degree of temperature and without a sign of diarrhea. If an evacuation occurs, it usually consists of green, mucous stool, which may be very offensive, although this is not always the case. The milder cases are characterized by an elevation of the tempera- ture and varying degrees of prostration. Pathology.—The intestinal lesions in these cases are of slight signifi- cance. There is perhaps an area of congestion here and there in the lower ileum or colon, with enlargement of the solitary follicles and epi- thelial desquamation. Treatment.—As mentioned above, there may be moderate diarrhea or marked bowel inactivity. In both conditions castor oil in doses of never less than 2 drams is to be given. Milk should be discontinued whether the patient is bottle fed or nursed. As a substitute, barley- water, rice-water, or Granum-water No. 1 (p. 94) may be given, with salt and cane-sugar or saccharin added for flavoring purposes. The treatment of these cases is facilitated by the fact that, owing to the ab- sence of vomiting, the food is usually well taken throughout the entire illness, the patient ordinarily being very thirsty. In the event of excessive diarrhea—a rare condition—the indications for medication are the same as those given under Acute Gastro-enteric Intoxication (p. 237). Castor oil or bicarbonate of soda is to be preferred to calomel at the beginning of the illness. Intestinal infection with defective bowel action (;paralytic ileus) often occasions the most difficult cases and requires special treatment. In 242 THE PRACTICE OF PEDIATRICS this type poisons generated apparently in the intestine seem to be of such a nature as to cause a partial paralysis of the small intestine, so that often, only with the greatest difficulty, can an evacuation be induced. So difficult is this, in fact, that the possibility of an acute peritonitis or an intussusception may occur to the physician. It is then very necessary to maintain bowel action and to prevent the accumulation of gas, which, by distending the intestine, increases the tendency to constipation and toxemia. Illustrative Cases.—A case in point is that of a female infant nine months of age who had been most difficult to feed. In July she developed a sudden fever of 105° F. and convulsions, which were followed by muscle twitchings, head-rolling, and marked prostration. The temperature was uninfluenced by local means, although there was no diarrhea or vomiting. The attending physician, anticipating intestinal infection, gave calomel in divided doses with frequent bowel irrigation. Foul-smelling fecal material came away with the irrigation, but the temperature and the nervous symp- toms persisted; in fact, the condition became worse. After the child had been ill ten or twelve hours | ounce of castor oil and a high irrigation of normal salt solution at 80° F. were given. As a result there was one small green movement in addition to what came away with the irrigation, which was considerable. The patient was somewhat relieved and the nervous symptoms measurably subsided, though the tem- perature still ranged between 104° and 105° F. As a result of the calomel, 1| grains of which had been given, and the J ounce of oil, a free diarrhea had been expected. It did not, however, occur. Directions were then given that 5 ounce of castor oil be given daily in addition to the irrigations every eight hours. This was followed by slight improvement in the symptoms, but five days of the treatment wTere required, 5 ounce of oil and 1 grain of calomel being given daily, with abdominal massage, before the resulting peristalsis was sufficient to relieve the intestine of its contents. After the establishment of free bowel action the child recovered. A similar case which resulted fatally was seen in consultation. In this patient, a girl eight years old, the toxemia was intense. There appeared to be almost complete paralysis of the small intestine, and only small, very foul evacuations could be induced in spite of the most active measures. This child died from toxemia before free bowel action could be established. The management of these cases of the inactive type is partially il- lustrated in the histories above given. Our efforts are to be directed toward supporting the patient by the use of stimulation, given hypoder- mically or by the stomach, and by the use of a milk-free diet, powerful laxatives, and frequent colon flushings. Castor oil may be required repeatedly, and should be given freely in doses of at least | ounce every twelve hours, until four or five passages in twenty-four hours result. Bi- carbonate of soda (p. 237) is given with beneficial results in cases of this type. While the fever, prostration, and bowel inactivity persist it is necessary to continue the irrigations. In a few cases apparently better results have been secured by using for the irrigations cold water (70° to 80° F.), with the addition of Epsom salts, 1 ounce to the pint. Stimulants.—Because of the tendency to convulsions and nervous irritability strychnin should not be given. The tincture of digitalis or strophanthus answers better than any other heart stimulant. Alcohol should be used only under the most urgent conditions of prostration. Atropin sulphate, from 1/1000 to 1/400 grain given hypodermically, is probably our most valuable drug for immediate stimulation. It may be repeated at four- to six-hour intervals. A combination of tincture of strophanthus and brandy, or digitalin and brandy, given hypodermically is of value. For a child six months of age 20 minims of brandy with 1 ACUTE ILEOCOLITIS (DYSENTERY) 243 drop of tincture of strophanthus, or 20 minims of brandy with 1/300 grain digitalin, may be given and repeated every two hours if necessary, according to the requirements of the case. After the first year children may be given as much as 1 /100 grain of digitalin or 2 drops of the tincture of strophanthus. Irrigation of the colon (p. 855) is a measure of inestimable value, both for its immediate local effect and also for increasing general peristalsis and thus emptying the small intestine. An increase of the peristalsis is sometimes well secured by the following procedure: After the colon is washed with a normal salt solution at a temperature of 95° F. the tube is introduced as far as possible and 8 ounces of saline at 60° F. is allowed to escape. The tube is immediately withdrawn and an attempt is made, by elevating the buttocks and pressing them together, to have the child retain the solution for a few moments. In using nutrient enemata and in colon flushing for purposes of supply- ing fluids to the circulation we have found that the solution is best re- tained when introduced warm—at a temperature of about 100° F. The cooler the solution, the more quickly is it expelled through exciting peris- talsis. This fact may be taken advantage of in these cases of bowel inactivity. After an enema of cool water peristalsis of the small intestine will often result in the passage of a considerable quantity of its contents into the colon, to be expelled later with the water. The action of the cool water will be further assisted by light abdominal massage main- tained after the tube is removed. Recovery may follow the clearing out of the intestine, or an ileocolitis may result, as in gastro-enteric intoxica- tion. The process of transition from enteric intoxication to actual ileo- colitis may require but a surprisingly short time, and if recovery is not prompt, ileocolitis will almost certainly be the outcome. Upon resuming the milk diet the precautions relating to the use of cow’s milk, referred to under Acute Gastro-enteric Intoxication (p. 238), must be observed. In dysentery there is a well-defined infection of the intestine. In common with other intestinal disorders it occurs most frequently dur- ing the hot months, the later summer and early autumn supplying the most cases. In like manner this disease often follows the milder gastro- intestinal derangements that are productive of reduced vitality and di- minished intestinal resistance. Bacteriology.—In a large percentage of cases of infantile diarrhea associated with blood and mucus in the stools the dysentery bacillus is present. It may be found in large numbers, sometimes in almost pure cultures. Duval and Bassett, in 1902, were the first to find Bacillus dys- enterise in the stools of cases of infantile summer diarrhea. The type of the bacillus which does not ferment mannite (the Shiga type) is not found so often in these cases as are the two mannite-fermenting types: the Flexner-Manilla and the Hiss-Russel, of which the former ferments mal- tose, saccharose, and dextrin, and the latter does not. The presence of agglutinins in the blood of the patient is evidence of the causal relationship of Bacillus dysenteriae to the existing disease. ACUTE ILEOCOLITIS (DYSENTERY) 244 THE PRACTICE OF PEDIATRICS The agglutinins are not present, as a rule, until the second week of the disease. Pathology.—The lower portion of the ileum-—rarely more than 3 feet •—and the colon are the locations of the lesion which may show a wide variation in intensity, depending on the character of the infecting organ- ism and the resistance of the patient. While the major lesions are usually in the colon, the small intestine shows pathologic changes in at least 35 per cent, of the cases. There may be localized areas of congestion through the intestine, enlargement of the solitary follicles, and swelling of Peyer’s patches. In nearly all cases, whether the lesions are mild or severe, mod- erate swelling and congestion of the mesenteric glands may be noted. The inflammation may be acute or chronic, and catarrhal, ulcera- tive, or pseudomembranous in type. Although the term “dysentery” is properly used to denote only infections by the bacilli of Shiga and Flexner and the special protozoon, Amoeba coli, the lesions produced may be conveniently considered under the term “ileocolitis.” In a series of 82 autopsies upon cases of ileocolitis Holt found fol- licular ulceration predominant in 36, catarrhal inflammation in 26, mem- branous inflammation in 14, and catarrhal inflammation with superficial ulceration in 6. Of 412 cases studied by Holt and Flexner in 1903, 270 showed the presence of Bacillus dvsenterise, the Flexner acid-forming type of organism appearing most frequently. Strains intermediate be- tween the Shiga and Flexner bacilli are occasionally found, and in the causation of a certain proportion of cases of epidemic dysentery Bacillus pvocyaneus has been shown to be active. Amebic dysentery is common only in tropical or subtropical regions. In simple ileocolitis of the mild catarrhal form the submucosa is but slightly involved. The mucosa, however, is swollen, congested, covered with secretion, and dotted with occasional points of hemorrhage and spots of epithelial exfoliation. The lymph-follicles are swollen and hyper- trophied, and the adjacent connective tissue is infiltrated with round cells. Microscopically, this infiltration is also apparent about the vessels in the submucosa. The stools are ordinarily green and thin in con- sistence, and contain mucus, desquamated epithelium, and traces of blood. In severe cases the inflammation acquires the ulcerative or membranous character, the lymphoid follicles are elevated and superficially necrotic, and the submucosa is infiltrated with pus. In such instances the ulcera- tions extend deeply, and exceptionally involve the entire intestinal wall. The Ulcerative Form.—In ulcerative ileocolitis the ulcers may origi- nate in the solitary follicles, and are then small, superficial, round, yellow, sharply defined, and surrounded by an inflammatory zone. Later the ulcers may grow larger, coalesce, and become deeper, exposing the sub- mucosa or even the muscularis. Ulcers may also originate in the mucosa itself and not in the follicles; this may occur in dysentery or in cases of severe catarrhal inflammation. As a consequence of the coalescence of these ulcers the mucosa has a ragged appearance, with islands of gray or congested mucous membrane visible between the irregularly shaped ulcers of all sizes. Small ulcers heal completely, but large ulcers rarely undergo such healing. Stenoses as the result of cicatrization of these ulcers do not occur in children. In cases of long standing all the intestinal coats ACUTE ILEOCOLITIS (DYSENTERY) 245 are thickened due to inflammatory infiltration, and the mucosa becomes pigmented. In pseudomembranous ileocolitis the intestinal mucosa is covered with a fibrinous exudate, which, can be rubbed off at first, but later is very adherent. The mucosa becomes necrotic, and larger or smaller areas are lost, leaving a congested, edematous base, surrounded by necrotic tissue. The pseudomembrane becomes colored yellow or greenish by the feces. The wall as a whole is thickened. The lesion is usually most marked in the colon, but the lower ileum is often involved. Healing may occur, but is rare; death is the rule. Associated Lesions.—In severe cases of ileocolitis the mesenteric lymph-glands are involved and the spleen may be enlarged. Perforation of the bowel, abscess of the liver, nephritis, and bronchopneumonia are occasional complications. Symptoms.—A great deal of confusion has been occasioned by at- tempts at a nomenclature of the acute inflammatory diseases of the intestine which shall make the clinical aspect of the cases fit the patho- logic findings. Differentiation, antemortem, into catarrhal, follicular, and ulcerative types is impossible, as has been proved by the care and daily observation in institution and hospital work of cases that have later come to autopsy. Consider briefly, for illustration, the gravest cases—cases which at autopsy show most extensive ulceration of the intestine. In many of these there has been a low temperature—from 100°. to 102° F.—and the stools have never contained a particle of blood. In others in which perhaps considerable blood has been passed for several days, there is but a mild congestion of the mucous membrane of the large intestine. In still other cases which continue for a considerable time—from two to three weeks—with moderate temperature, death results from exhaustion, and autopsy.shows nothing but an enlargement of the solitary follicles, with areas of congestion in the lower portion of the small intestine. Acute ileocolitis may be the primary intestinal disease. In this con- dition the temperature is usually considerably elevated at the commence- ment of the illness—103° to 104° F. After an evacuation of two or three undigested stools the passages consist of light-colored mucus, often streaked with blood, or they are of green mucus and streaked with blood. In some cases there is a considerable hemorrhage. Relaxation of the sphincter and prolapse of the rectum are not at all unusual. The passages are small, frequent, and attended with considerable pain and tenesmus. Repeatedly from twenty to thirty such passages will be observed from one patient in twenty-four hours. Far more frequently, however, this condition follows acute gastro- enteric indigestion or an intestinal infection, the dangers of which have not been appreciated, and which, in consequence, has been improperly treated. The lesions produced are due to the bacteria and their toxins, which have abundant opportunity to produce pathologic changes in the intestinal mucous membrane, the extent of which can only be conjectured during life. An important feature of some of these cases is that an extreme degree of toxemia, with resulting prostration, may be present, with little fever 246 THE PRACTICE OF PEDIATRICS and insignificant bowel symptoms. In other cases the bowel manifesta- tions are very active and the toxemia is slight. The active cases offer the better prognosis. Vomiting may be present at the onset of the attack, but is not usually a symptom of consequence. There is always emacia- tion. The degree of prostration is dependent upon the amount of toxemia, the extent of the lesion, and the management of the case, particularly as relates to supportive measures and nutrition. Duration.—The duration of ileocolitis is longer than that of any of the intestinal disorders previously mentioned. With the disease established it is rare for a case to recover under ten days. Oftener the duration of the illness is two or three weeks and we have repeatedly known cases to continue over four weeks. In fact, the duration in many instances is similar to that of typhoid fever. The temperature range is variable—from normal to 104° F. For three or four weeks in a given case there may be a low temperature range—99.5° to 101.5° or 102° F. Treatment.—Recent work in the bacteriology of the acute intestinal diseases has added little to our practical knowledge as to the treatment of the condition, and consequently does not call for discussion here. Milk is to be stopped at once, whether the patient is breast fed or bottle fed. Barley-water, Granum-water, or rice-water No. 1 (see Formulary, p. 94) constitutes the basis of diet for children under one year of age. Older children may be given the No. 2 mixture. To these carbohydrate foods may be added an ounce of chicken or mutton broth, with salt or sugar to make them more palatable. It is well, for variety, to make up two or three cereal preparations and alternate their use. In this way the foods will be better taken and for longer periods than if but one is pre- pared. In this form of substitute feeding an amount similar to what the child was accustomed to in health may be given, but the intervals may be shorter by one-half hour or one hour. To patients of any age two or three feedings of protein milk (p. 88) mg,y be given daily. It supplies additional nutrition, and if the disease is prolonged, there is correspondingly less emaciation. In using the protein milk it should at first be diluted with barley-water—\ milk to f water at first, to be increased to \ milk and \ barley-water. In cases in which the standard protein milk is not well taken or is vomited, the improved product made from evaporated milk (p. 78), with a shortened incubation period, has been often employed with much advantage. Drugs.—One has abundant opportunity to test the value of the dif- ferent drugs advocated from time to time for the treatment of this disease. Drugs which have proved of unquestioned value are castor oil, subnitrate of bismuth, and opium. Drugs which have an occasional application are sulphur and the preparations of tannin. Constitutional measures, sup- portive in character, such as heat and stimulation, are, of course, used when indicated, as in any severe exhaustive illness. At the commencement of the attack 2 drams of castor oil should be given. If this is not retained, from 1 to 2 grains of calomel should be given in divided doses—\ grain every hour. In cases with considerable fever and infrequent stools it is well to repeat the oil or give some other laxative, such as magnesia, every two or three days. Bismuth subnitrate is best given in 10-grain doses, according to the ACUTE ILEOCOLITIS (DYSENTERY) 247 suggestions on p. 237. If black stools do not follow its administration, 1 grain of precipitated sulphur may be added to each dose. To be effec- tive the bismuth must be given in large doses; 2 or 3 grains at inter- vals of two or three hours are of no value. To patients over one year of age 15 to 20 grains are frequently given at two-hour intervals. The writer has used bismuth extensively for children during the past twenty- five years, and has yet to see harm resulting from its use. Of course, the physician must use a pure article. Not a few cases do admirably under the cereal-water diet, castor oil, bismuth, and sulphur. Tannalbin, in doses of 2 grains for infants, and from 5 to 8 grains for older children, is sometimes of service when there is a tendency to large watery stools or stools containing large quantities of mucus. This drug also may be given at the same time as the bismuth. When there is much pain and tenesmus, with frequent, scanty, mucous stools, opium may be used with advantage, with a view to controlling the tenesmus and diminishing the frequency of the stools. Paregoric or Dover’s powder is usually selected for this purpose. Dover’s powder is preferred, because of the absence of a disagreeable taste and the con- venience of its administration. It may be added to the bismuth at each dose, not combined with it in a prescription, for uncombined it may be at once discontinued or given in smaller doses upon a diminution in the number of the stools. Careful instructions should be given when prescribing opium. It is to be given for a definite purpose—to prevent straining and the fre- quent passages due to excessive peristalsis. As in the treatment of acute intestinal infection, particularly if there is temperature, it is not well to attempt to reduce the number of the stools below four or five in twenty- four hours, and, of course, opium is not to be given at all unless the stools are very frequent. The amount of opium that will be required in a given case may readily be determined by carefully watching the character and frequency of the stools. For children under one year of age the dosage of Dover’s powder is from | to \ grain at two-hour intervals, not more than seven doses being given in twenty-four hours. From the first to the tenth year the dose ranges from \ grain to 2 grains. Mothers and nurses should be instructed that when there is a rise in the temperature, or when the child becomes drowsy after its use, the opium is to be dis- continued or the dose reduced one-half—another advantage of giving it independently. The younger the child, the greater caution to be observed. When heart stimulants are necessary the tincture of strophanthus may be used in case digitalis is not well borne by the stomach. Because of its unfavorable effect upon both the stomach and the kidneys, alcohol should be given with caution, and when used should be well diluted and given only temporarily—during the urgent period of acute toxemia. Prolonged use of alcohol invariably interferes with the stomach function. Caffein sodio-salicylate, in to 1-grain doses at two-hour intervals, and atropin, to grain at four-hour intervals, are particularly useful in the asthenic cases. For threatened collapse camphor, 1 to 2 grains hypodermically in oil, answers well, but requires frequent repeti- tion at one- to two-hour intervals. Adrenalin 1 : 1000 solution in 2- to 3-drop doses, hypodermically, is also of much service in collapse. 248 THE PRACTICE OF PEDIATRICS Hot Applications.—Hot stupes or hot compresses to the abdomen are often most grateful to the patient when there is abdominal pain and tenesmus. The hot applications should be changed every fifteen or twenty minutes, never being allowed to become cold. Colon irrigation should be used at least once in every case of colitis, normal salt solution being employed at 100° to 105° F. The solution should always be used warm, as it at times has a pronounced sedative effect when used in this way, and thus may fulfil two purposes. Whether the irrigation is repeated or not must depend upon its effect upon the patient. When he strains against it and there is no apparent diminution in the num- ber of the stools, it should not be repeated. Frequently, however, the intestine remains quiet and the number of passages is diminished after a warm irrigation—105° to 110° F. In such cases it may be repeated twice daily. In cases in which there is not an active bowel action, and decom- posing blood and mucus are removed by the washing, it may be used once or twice daily. Only in the rarest instances, when there is high fever and bowel action is delayed, should intestinal irrigation be practised oftener than once in twelve hours. This treatment is often overdone. Irrigation should always be used for a definite purpose, and discontinued when that pur- pose is accomplished. Every year, at the close of the heated term, one sees cases of chronic colitis without fever which are being treated by irrigations two or three times daily without any indication for the irriga- tion other than the mucous stools. Irrigations, without question, help to keep up the secretion of mucus, for repeatedly it has disappeared en- tirely in a few days without other treatment after the discontinuance of the irrigation. When irrigation is practised frequently in cases with inactive peristalsis it is possible to produce a general edema due to the absorption of the fluid. This has been done experimentally in well children. Starch and Opium.—The time-honored remedy—the injection of starch and opium—may be of service in the cases in which there is much tenesmus, with the passage of small amounts of blood-streaked mucus or the discharge of bloody mucus from the rectum. In these cases the principal lesions are usually located in the sigmoid and rectum. A straight- pipe, hard-rubber syringe answers best for this purpose. A starch solu- tion of the strength of 1 dram of starch to 1 ounce of boiled water is used. For infants under one year of age 5 drops of laudanum may be added to 2 ounces of the starch solution, and repeated at intervals of six to eight hours. Older children may be given from 8 to 12 drops of laudanum with 4 ounces of the starch solution, and this may be repeated in four to six hours. Improvement in the colitis is indicated by a subsidence of the tem- perature, a change in the character of the stools from green or clear mucus, with blood and scarcely any odor, to passages which gradually take on a fecal odor and show the presence of feces mixed with mucus. Infusion and Transfusion.—In cases that are doing badly, in which exhaustion and dehydration are marked, transfusion is of great service. If this is not possible, hypodermoclysis or intraperitoneal injection of normal salt solution may be employed (pp. 850-851). Serum Therapy.—The use of antidysenteric serum and solutions of ACUTE ILEOCOLITIS (DYSENTERY) 249 bacteriophage or bacteriolysin is theoretically rational and is advocated by many workers, but thus far the results in general have not been par- ticularly striking. Further advance in the treatment of dysentery will probably be along the lines of serum therapy, or from further knowledge of the mechanism of the D’Herelle phenomenon. Practical results thus far do not warrant further discussion here. The Influence of Climate.—When the case is under control, a change of climate is most beneficial. A child who has had colitis at the sea- shore or in town will invariably have recovery hastened by a removal inland to the mountains, where an open-air life is to be insisted upon. Diet in Convalescence.—With a subsidence of the fever and an improve- ment in the number and character of the stools the patient’s troubles are not over. The problem of nutrition is often difficult. The child has necessarily been on a reduced diet for several days—often for two to three weeks. If better nourishment than cereal gruels and protein milk is not soon forthcoming, the patient faces the danger of malnutrition and maras- mus, which is the outcome in not a few of the badly treated cases in which the disease is not quickly fatal. The use of fresh milk must sooner or later be attempted. In nearly all these cases the child has not been getting sufficient caloric units for maintenance of weight. This applies particularly to children, who, on account of age or refusal to take it or intolerance, have not had the benefits of protein milk. Children who have had colitis bear fat badly. The younger the child, the more certainly is this the case. This has been so forcibly impressed upon the writer that he has discontinued attempts at feeding these con- valescents, even with small quantities of whole milk. They do best on a carbohydrate gruel as a basis of diet, to which sugar-of-milk is added in the proportion of from § to 1 ounce to the pint, thereby furnishing material for heat and energy. To this sugar-cereal combination boiled skimmed milk in small quantities is added; not over | ounce, and that to only one of the feedings, the first day that milk is given. If this causes no in- convenience, an increase of § ounce is made at every second feeding the following day, and an increase of ounce at every feeding the third day. The total quantity of food given at each feeding is to remain the same, an equal quantity of the cereal diluent being removed to make way for the milk increase. Thereafter, if all goes well, an increase of \ ounce is made in each feeding every day until the child is taking his daily feedings of skimmed milk one-half strength. In some cases it may be found that the child’s capacity will be only 2 ounces of skimmed milk at a feeding with the cereal-water diluent. Here he must be held, perhaps, for a week or two before milk can safely be advanced. Usually the younger the child, the more difficult will be the resumption of the milk diet. After the first year the nutrition may be assisted by thick gruels of vary- ing types and compositions, zwieback, bread crusts, or rare scraped beef—two or three teaspoonfuls daily, with a couple of feedings of protein milk or buttermilk. By infants under one year of age who cannot take even a weak dilution of skimmed milk, Granum No. 1 (p. 95) will usually be well taken. If there is abdominal distention from starch indigestion the Granum may be dextrinized. Cereal-water also answers well as a 250 THE PRACTICE OF PEDIATRICS diluent for evaporated milk. In adding evaporated milk to the cereal- water sugar is to be omitted. The evaporated milk may be increased slowly until from 1 to 4 drams are given at a feeding. Under no ordinary considerations, however, should this diet be permanent. After from two to four weeks the use of plain milk should be attempted, replacing one feeding of the evaporated by a small amount of diluted plain milk. Obstinate constipation sometimes follows recovery from severe ileo- colitis. This is to be managed along the lines laid down for the manage- ment of constipation (p. 267). Following an attack of ileocolitis the patient must never be allowed to pass twenty-four hours without an evacuation of the bowels. A standing order should be given that an enema should be used when no movement occurs. CHRONIC ILEOCOLITIS Cases of chronic ileocolitis coming under our observation have in- variably been preceded by acute attacks that were unusually severe or that were badly managed. These cases represent one of the forms of mal- nutrition, but are of such a nature as to require special consideration. Pathology.—The walls of the intestines are thickened with connective- tissue formation, and the solitary follicles have undergone pigmentation as a result of hemorrhages or extreme congestion. Symptoms.—The patient is emaciated, and often 3 or 4 pounds under weight; the skin is dry and rough; the circulation is poor; the extremities are cold, and the temperature is often subnormal, showing an occasional sharp rise. The abdomen is always distended with gas. The stools usually are loose, number three or four daily, and contain mucus in considerable amount. The mucus may be absent for two or three days; then there will be a rise in temperature of from 102° to 105° F., and large quantities with a very foul odor will be passed. The nervous symptoms are usually marked. The child is irritable and sleeps poorly. He cries a great deal, is very unhappy, and looks as wretched as he apparently feels. In assuming the care of one of these cases it is well to inform the parents that a rapid improvement is not to be looked for. Illustrative Case.—A patient aged three and one-half years, who eventually recov- ered, weighed but 23 pounds—2 pounds less than when she was eighteen months old. During the first six months of treatment there was very slow improvement in spite of every advantage that care and change of climate could afford. Treatment.—The management consists in a proper diet, change of climate when possible, and supportive measures. It is for the physician to find out in a given case what means of nutrition are best. These cases vary considerably in their digestive possibilities, with the exception that they all bear fat foods badly. Diet.—Chronic colitis is very fatal in young infants, and but few survive. By far the best food for infants under one year of age is breast milk, which at first must be given in small quantities. Sugar-water should be given before the nursing. These young infants do not do well on starchy foods unless they have been dextrinized (p. 95); and when predigested they may have too laxative an effect, and should be given in MUCOUS COLITIS 251 small quantities. The use of starch, therefore, in these cases, for a con- siderable time at least, is limited. Standard protein milk and buttermilk have failed the writer repeatedly in feeding these young children. It is the improved protein milk (p. 89) that has given the best results in such cases. The patient may be able to digest the unsweetened condensed milk in the proportion of 1 : 6 to 12 of water or weak gruel diluents. Two or three feedings a day may be given in alternation with a dextrinized gruel. The addition of | ounce of gelatin to the pint of food makes a desirable addition to the feeding of mal- nutrition cases in which food of low caloric value is necessary. The beaten white of egg may be given in diluted skimmed milk or in dextrinized gruel No. 3 (p. 95) if it agrees, or in plain water with salt added. The whites of two or three eggs may thus be given daily with benefit. For older children, after the first year, skimmed milk, protein milk, rare scraped meat, junket, and coddled white of egg are usually best. Zwieback or bread crusts may be given in small quantities. Alcohol, if given at all, should not be long continued. It is well to feed these patients five times a day at four-hour intervals. There should be a standing order for an enema after an interval of twenty-four hours if no bowel movement takes place during that time. Absence of bowel movement in these cases almost invariably is followed by fever, prostration, and perhaps convulsions. If there is a tendency to constipation, some laxative, such as magnesia, mineral oil, or the aromatic fluidextract of cascara, should be given daily in sufficient amount to insure at least one free evacuation. Irrigation of the colon is not to be used as a routine measure. It is indicated whenever there is a rise in temperature, even though the bowels have moved but a few hours previously. A laxative, preferably castor oil or calomel, should also be given. The further treatment calls for salt baths, oil inunctions, and the open-air life referred to in the section on Malnutrition, p. 146. MUCOUS COLITIS Mucous colitis is a chronic catarrhal condition of the colon, char- acterized by the production of very large quantities of mucus. The mucus forms a pseudomembrane over the mucosa, and is passed in the form of casts or large worm-like masses. Attention has elsewhere been called to the necessity, in dealing with some of the diseases of children, of ignoring what appears to be a local manifestation of disease, and treating the patient along dietetic and hygienic lines. This necessity is in no instance better illustrated than in the case of mucous colitis, a disease fortunately rare in children, yet of sufficient frequency to warrant our attention. Etiology.—The patients treated have invariably been of a pronounced neurotic type, usually of neurotic ancestry, and invariably from a neuro- pathic environment. It is quite usual to find that a considerable quantity of milk has been taken daily. Ptosis of the transverse colon and the elon- gated or ptosed sigmoid (p. 255) may be in part responsible for some of these cases. 252 THE PRACTICE OF PEDIATRICS Symptoms.—The disease rarely follows an acute inflammatory proc- ess in the intestine. In the majority of instances there is a history of obstinate constipation in a markedly neurotic, underfed child. Con- stipation may have existed during the patient’s entire life. Almost without exception the treatment which has been followed has consisted in the use of colon irrigations and various kinds of astringents, such as solutions of tannic acid, nitrate of silver, etc. In children with mucous colitis the appetite is capricious, the bowels are usually constipated, and the disposition is chronically irritable. These children are apt to com- plain of ill-defined pains in the abdomen, which are never very severe and are not necessarily associated with the taking of food. There is usually slight generalized abdominal tenderness. A child four years of age, however, whose case was the most pronounced ever under our care— never had the slightest evidence of pain of any character. With the de- jections there is usually mucus in considerable amount, which is occasion- ally passed in large masses, at other times in long, tenacious strings, sometimes referred to as “ropy.” During a period of several consecutive days little or no mucus may be passed; then large amounts will suddenly appear. Treatment.—These cases respond most quickly when local measures which often are irritant to the intestinal mucous membrane are dis- carded. Usually, as a result of previous treatment and because of the nature of the disease, the constipation is most obstinate. To prevent this an injection of 2 to 3 ounces of olive oil is employed at bedtime, the tube being introduced 8 inches into the bowel. After breakfast on the following morning the child is placed at stool, and if no passage occurs within fifteen minutes, a glycerin suppository is inserted. By this means one passage daily is insured, and this, ordinarily, is all that is required. The use of the suppository is to be discontinued after a very few days, as soon as the habit of evacuation at a certain time is established. Should this method fail, from 1 to 2 drams of the aromatic fluidextract of cascara may be given in addition, at bedtime, this medication being gradually diminished and discontinued as soon as it is demonstrated that an evacua- tion will occur without medication. A remedy of considerable value is the liquid petrolatum given in dosage of | ounce to 2 ounces at bed- time, and continued in gradually diminishing doses until the stools are free. Local measures other than those suggested for constipation are not to be employed. Diet.—Not infrequently these patients have been taking a consider- able amount of milk. This is to be immediately discontinued. In its place malted milk or whey may be given. The further diet consists of whole-wheat bread, animal broths, cereals cooked three hours, eggs, poul- try, red meat, stewed fruit, and fruit juices. Spinach, stewed carrots, and asparagus-tips are the only vegetables allowed at the beginning of the treatment, and these by no means should always be given. Puree of peas, beans, and lentils may be given freely. The use of butter is to be encouraged in amounts up to 3 ounces daily. It may be given on bread or on the cereal. Drugs.—Strychnin and mix vomica appear to exert a very beneficial influence on these cases.

A child suffering from mucous colitis invariably shows a considerable degree of malnutrition.

DEVELOPMENTAL ABNORMALITIES IN THE INTESTINAL TRACT AS A CAUSE OF DIGESTIVE DISTURBANCES As stated on page 221 observation with the Roentgen ray in associ- ation with constant clinical supervision has opened up an entirely new field in the etiology of persistent intestinal disorders in children. Fig. 42.—Normal sigmoid in a child of three years. Due to abnormalities in structure and in the relations of various portions of the intestine there results a derangement of function with disturbed physiologic and chemical processes which makes for faulty nutrition, defective growth, and inferior general development of the child, both physical and mental. Mechanical defects of the intestine, such as ptosis of the colon, dilata- tion of the colon, dilated cecum, and the long sigmoid are the abnormal- ities most frequently encountered. The ptosed colon is usually associ- ated with dilatation and ptosis of the stomach (p. 221) and is probably secondary to that condition. Conversely, one of the most interesting 254 THE PRACTICE OF PEDIATRICS facts brought out in our £-ray studies is the dependence of stomach re- tention upon irritation somewhere in the lower bowel. The ‘‘gradient idea” of Alvery1 fits these cases admirably. Children with stomach retention of this particular type have almost every form Fig. 43.—Female aged nine years. Elongated sigmoid passing above level of trans- verse colon (LeWald). of gastric manifestation, and their histories of loss of appetite, belching, vomiting, and pain, either paroxysmal or constant, mild or severe, and at 1 Mechanics of the Digestive Tract, Hoeber, 1922, DEVELOPMENTAL ABNORMALITIES IN THE INTESTINAL TRACT 255 times gnawing, in character, have so impressed us that our first thought in treating a disorder of the stomach is to attend to proper intestinal elimination. In several cases later to be mentioned periodic vomiting Fig. 44.—Female aged two and one-half years. “Double-barreled” transverse colon. Appearance due to enlongated sigmoid flexure passing across to right side of abdomen and above crest of right iliac bone (LeWald). was entirely relieved by curing rectal constipation, a result obtained in one instance by stretching the sphincter ani. Many children have been relieved by the correction of other abnormalities. 256 THE PRACTICE OF PEDIATRICS We shall have much to say upon the abnormalities of the large in- testine. Figure 42 shows what may be looked upon as an anatomically normal large intestine. It is appreciated that there are always variations in the normal; only those showing gross abnormalities will be discussed. The Elongated Sigmoid.—The most frequent abnormality consists in an elongation of the sigmoid (Figs. 45-46), which may be from two to four times the length given as normal in works on anatomy. This anomaly is of congenital origin. It is stated that such elongation always causes symptoms. Much depends upon the size of the pelvis and whether there are associated dilatations and sacculations. That there are children with markedly elongated sigmoids who are in no way inconvenienced is fully appreciated, but whether they will go through life without trouble Fig. 45.—Three minutes after injection—redundancy of sigmoid amounting to about three times average length. Appendix partly filled. is another question. The fact remains that when attention is directed toward relieving whatever fault may be occasioned by the deformity, the patient with rare exceptions makes a very ready response. The following illustrations together with the accompanying case notes are intended to present this subject more concretely. The history of the case represented in Fig. 43 is as follows: A girl aged nine years and weighing 54 pounds showed hemoglobin 40 per cent, and red blood cells 4,000,000. She was of delicate appearance, and made very slow gain in weight. About every two months she had so-called bilious attacks simulating recurrent vomiting and accompanied by high fever so that she was in bed for several days with each attack. The bowels were habitually constipated and daily laxative medication was required. The breath was offensive. The Roentgen ray revealed ptosis DEVELOPMENTAL ABNORMALITIES IN THE INTESTINAL TRACT 257 of the stomach and showed that the organ failed to empty itself in seven hours. There was also marked ptosis of the transverse colon and marked elongation of the sigmoid. Fig. 46.—Male aged three and a half years. Elongated sigmoid. One of the most extreme types encountered. (LeWald.) Figure 44. A girl, aged two and one-half years, weighing 25 pounds and giving evidence of moderate malnutrition, showed hemoglobin 55 per cent, and red blood cells 4,600,000. She had had three convulsions of gastro-intestinal origin in the previous year. For her habitual consti- 258 THE PRACTICE OF PEDIATRICS pation medication or an enema was required daily. The urine showed a moderate amount of acetone. The Roentgen ray revealed an elongated sigmoid passing 2 inches above the umbilicus. When the child was in the prone position the sigmoid passed to the right as far as the lateral abdominal wall. Figure 45. A girl five years of age was subject to repeated attacks of vomiting and obstinate constipation, the vomiting seizures occurring about every two months, continuing two or three days, and leaving her Fig- 47.—An elongated colon which had assumed a spiral form to adjust itself to the pelvic capacity. The sigmoid is also greatly elongated and there is marked length- ening of the colon to about four times its normal length. The patient, a girl three years of age, but recently came under observation because of repeated vomiting seizures, occurring about once a month, lasting from twenty-four to thirty-six hours, and accompanied by convulsions and high temperature. much reduced and weak. It will be observed that the sigmoid in this case is about three times its normal length. Figure 46. A boy, three and one-half years of age, weighing 32 pounds showed a markedly elongated and prolapsed sigmoid. The history given by the mother was substantially as follows: “The boy has had acute gastro-intestinal attacks since birth, with vomiting, diarrhea, and fever, acute seizures lasting three to four days during which he loses a pound or two of weight. During the past year two months have not elapsed without such an illness. Between attacks he is consti- pated and requires medication. He has frequent pains in the abdomen. DEVELOPMENTAL ABNORMALITIES IN THE INTESTINAL TRACT 259 Appendicitis has been diagnosed. Some of these seizures have been diagnosed as colitis attacks because of the passage of considerable quan- tities of mucus. He is irritable and very unhappy in disposition. His breath is habitually offensive; his tongue habitually coated, and his abdomen is distended a greater part of the time.” The Dilated Cecum.—The dilated colon and cecum appear to be dependent upon the accumulation of feces and gases brought about by the obstruction occasioned by the long sigmoid, with its angulation and defective peristalsis. Figure 48 represents the case of a boy thirteen years old who for six years had had severe attacks of pain definitely localized in the right lower quadrant. At first the seizures occurred only at intervals of three Fig. 48.—Dilated cecum and V-shaped colon in a boy of thirteen years. or four months, but later every few weeks. He had no vomiting; or con- stipation and only a moderate amount of nausea and anorexia, and this only at the time of the pain attack. The case had repeatedly been ciiag- nosed as one of appendicitis. No point of tenderness could be discovered, and between the attacks no tenderness demonstrable by manipulation or otherwise. Blood examinations had been made repeatedly and were always negative. There was moderate abdominal distention at the time of the attacks. This boy was large for his age and well nourished. The illustration shows the cecum so large that its shadow overlaps that of the sigmoid flexure and passes quite to the median line. The dilatation was probably secondary to retention produced by the V-shaped colon also shown in Fig. 48, the distention being the result of the back-up 260 THE PRACTICE OF PEDIATRICS or reverse peristalsis. The boy was given a simple diet of three meals daily, and liquid petrolatum in 2-ounce doses for several months. There had been no subsequent attacks of colic in the succeeding two years. The senior writer has had 5 cases of this nature with symptoms almost identical. It would seem beyond doubt that we have a definite clinical entity to deal with. Symptoms.—The symptoms referable to the above abnormalities are repeated attacks of acute indigestion with cyclic or recurrent vomit- ing, abdominal distention, habitual or intermittent, intestinal colic, constipation which may be extreme, diarrhea alternating with consti- pation, or habitually loose mucous evacuations, and periodic fever with intestinal manifestations. In addition to these active manifestations the patients are usually anemic showing secondary malnutrition. Their mental equilibrium is easily disturbed, they are apt to be unhappy irritable children, they sleep poorly and their appetite is capricious. A few show defects in stature. That arrested growth and anemia may be the result of abnormal intestinal function is readily understood when one realizes what a vital part the intestine plays in growth and development. Constipation alone, or with abdominal distention, is present in nearlv all cases. In those with diarrhea or habitually loose mucous evacuations there is always a history of previous constipation, and the relief of the constipation is the keynote of the management. Treatment for Constipation.—The selection of suitable food for a given case plays a large part in the management. For the constipation the following dietetic regulations are advised: White bread, toast, and crackers are omitted. Oatmeal, cornmeal, hominy, cracked wheat, and the coarse cereals are allowed. Potatoes, rice, milk, and eggs are given sparingly. Milk is often replaced by malted milk. Green vegetables are given twice a day. Stewed or raw fruits are given the preference as desserts. Fresh meats and fish are allowed. Whole wheat bread and oatmeal crackers are recommended. Raw fruits are given wifh the stomach supposedly empty, an hour to an hour and a half before meals. We have found such giving of raw fruits with the stomach empty one of the most valuable dietetic aids in managing constipation. We are speak- ing now of those cases without stomach involvement. Enemata for Temporary Purposes.—An enema may be employed, but it should never be given habitually. Marked dilatation of the rectum exists as a result of frequent enemata. Massage.—Properly applied, daily massage is almost indispensable in obstinate cases. Massage and suitable diet may have to be continued for several months. The Abdominal Belt.—Abdominal support of some sort is always of assistance in these cases. The writer has used the Aaron belt with an ad- justable shelf, the Bassler belt, and in those cases with lordosis and a pro- tuberant abdomen, a Universal Supporter (Lentz & Company, Philadelphia)} Medication.—Olive oil and liquid petrolatum are useful in connection with other laxatives, but rarely sufficient when used alone. What is 1 The latter device promises well. We have employed it in about 30 cases, but are not ready to pass upon its utility. Hirschsprung’s disease (idiopathic dilatation of colon) 261 required is an active peristalsis. In using laxatives, however, care is to be exercised to avoid purgation. Our best results have been obtained by the use of aromatic fluidextract of cascara given three times daily after meals in doses sufficient to produce one or two free evacuations daily. With the aid of massage and the oil the cascara may be gradually reduced. It should always be given after each meal no matter how small the daily dosage. Treatment for Diarrhea.—The child with diarrhea or with habitually loose evacuations, perhaps but one or two daily, is best treated by omitting stewed fruits and green vegetables entirely from the diet. Milk given these patients should be skimmed and boiled. The writer’s earlier results with this type of case were very satisfactory. Two cases under treatment at the time of this report, in both of which the sigmoid is greatly elongated, are, however, proving intractable and not much progress is being made with diet and medication. Surgical procedures may be re- quired in these cases. Although there may be a displaced colon or an elongated sigmoid, and a history of previous constipation, the stool should al- ways be examined in case of diarrhea for other possible causative factors. HIRSCHSPRUNG’S DISEASE (IDIOPATHIC DILATATION OF THE COLON) Two varieties of Hirschsprung’s disease are recognized—the congenital and the ac- quired. The condition is rarely encountered in its typical and extreme form. Only two well- marked cases have come under our observa- tion. There is an enormous dilatation and hypertrophy of the colon without constric- tion. The greatest dilatation is found in the transverse and descending colon. In the cases described by Hirschsprung there were ulcerative processes in the mucous mem- brane and submucous abscesses. Etiology.—In all cases the condition is probably based upon con- genital structural defects. Symptoms.—The prominent symptoms are obstinate constipation, symmetric enlargement of the abdomen (Fig. 49), and malnutrition. The bowels may act only once in three to six weeks. Complete ob- stipation of two or three months’ duration has been reported (Cautley). Respiration is often impeded because of pressure on the diaphragm. For a like reason the heart action may be interfered with. The hepatic and splenic dulness is obliterated. Fig. 49.—Hirschsprung’s dis- ease. 262 THE PRACTICE OF PEDIATRICS Prognosis.—The prognosis for a complete cure is unfavorable. The patient usually succumbs to intercurrent disease. Treatment.—Little is to be expected from treatment, whether medical or surgical. Various operative procedures have been attempted. The radical operation involving complete removal of the colon has been per- Fig. 50. Fig. 51. Fig. 52. Fig. 53. Figs. 50-53.—Megalacolon, dilated sigmoid, and markedly distended abdomen. formed. As long as it is possible to produce an evacuation of the colon the patient may remain in a fairly comfortable condition. Laxative drugs, massage, electricity, and colonic irrigations may all prove useful as temporary aids. The followipg case notes together with Figs. 50-53 illustrate the problem presented by a case of this type: CELIAC DISEASE 263 Male, aged seven years. Since birth extreme constipation. At eight months sigmoidopexy for prolapse of rectum, at which time dilatation of the colon with ad- hesions was noted. Roentgen Examination.—Enormously dilated hepatic, splenic, and sigmoid flexures (I’ig. 50), the sigmoid having a pouch-like appearance. Bilateral eventration of the diaphragm. Operation.—Many adhesions about the sigmoid divided. Roentgen Examination. Iwenty-two months later sigmoid greatly reduced in size. A tube instead of another injection was used to demonstrate this reduction, for the previous injection required two weeks for elimination (Fig. 51). Comment. Six years later physical condition excellent. Treatment had consisted or an injection of 8 ounces of warm water upon rising, followed by ten minutes of exer- cises. An abdominal belt had been worn. Roentgen examination showed that the splemc flexure, descending colon, and sigmoid had been converted into a uniformly dilated tube as a result of the operation (Fig. 52). The entire injection was evacuated in forty minutes (Fig. 53). CELIAC DISEASE In 1888 Gee described a disease of unknown etiology which has since been established as a clinical entity. Children with this disease closely resemble each other in almost as many points as those who are Mongolian idiots. Diagnosis can always be made by inspection. The face is thin and usually pale, but not drawn and weazened, as in the usual form of malnutrition of gastro-intestinal origin. The abdomen is distended with gas and has a doughy feel, the distention varying in different cases and at different times of day. In those in which there is marked distention the abdomen may be quite flat in the early morning and yet the size may progress with the day so that when the child retires the abdominal circumference will perhaps measure 3 or 4 inches in excess of the morning measurement. Taylor1 has called attention to the fact that this disease has never been recognized in a breast-fed infant, and from a review of 7 cases has deduced that ‘The best way to produce celiac disease is to feed a sus- ceptible child throughout the second year on a diet rich in milk, fat, and potato, and then to subject him to some parenteral infection.” In all of the cases of Taylor’s group the liver was smaller than normal, and in all of 5 cases examined gastric achlorhydria was present. Etiology.—The age at onset is variable. The writer’s youngest patient was nine months, and the oldest two years and eight months of age. Some of the patients gave a history of difficult feeding which, as a rule, meant cow’s milk incapacity, and in many instances the case only gradually took on the characteristics of celiac disease. Other cases are typified by the child represented in Fig. 141, p. 802. He was a strong vigorous boy until thirty-twro months of age, and then had a sharp attack of diarrhea followed by the chronic intestinal disturbance. Symptomatology.—In this disease the muscles of the entire body undergo atrophy. This is particularly noticeable in the arms and legs, in which the muscles are very small, flabby, and weak. The knees and feet are prominent and appear abnormally large. Muscular atrophy and muscular weakness is a comparatively early and very prominent sign and a condition slow to be recovered from when the child begins to improve. All evidence of normal nutrition is lacking and growth in height ceases. The patient may not increase an inch in height while the disease is active. 1 Celiac Disease, Amer. Jour. Dis. Child., vol. 25, January, 1923, p. 46. 264 THE PRACTICE OF PEDIATRICS In one case height was absolutely stationary for two and a half years, and at the end of this time the weight was 6 pounds less than at the outset. If the child has walked he soon loses the ability because of muscle weak- ness, and he is habitually irritable, sleeps poorly, demands entertainment and is not satisfied when it is supplied. The enlarged abdomen often gives rise to the diagnosis of abdominal tuberculosis and the stunted growth causes confusion in differentiation of celiac disease from the infantilism of Herter (p. 266). Hirschsprung’s disease also presents a similar train of symptoms. In both these condi- tions, however, there is a definite pathology. In the true cases of infan- tilism the child remains a dwarf (see descriptive case, p. 266). Our patients with true celiac disease have recovered with the exception of a small proportion. Those recovering have in* every way taken their place in the world with others of their age. That such individuals are permanently shorter in stature than would have been the case had the celiac disease not handicapped them, has not been proved by the few that have been followed to adolescence. These patients have another feature in common, persistent bowel derangement. The character of the stools is the same in all cases and is in itself diagnostic. The stools are loose, watery, sour, glistening, and usually foul, and of a greenish color, often presenting a spongy appearance as though undergoing fermentation. Occasionally there are periods of constipation, but this is not usual. Chemical examination shows the presence of fatty acids, unchanged fat, starch and mucus, the findings depending, of course, upon the nature of the food ingested. During the same year two patients under observation have developed a very obstinate tetany, and one of these had two attacks of scurvy on account of incapacity for food containing the antiscorbutic vitamin. Both patients were be- tween four and five years of age. One died from exhaustion and starva- tion while the tetany was active. The other when well on the road to recovery required treatment for postural defects caused by the prolonged illness and associated muscle weakness. Death in the writer’s cases has been due to acute exacerbations of the chronic diarrhea or to inanition. Management.—Internal medication has been of no service. We have given these children ductless glands, yeast, calomel in minute doses, pancreatic extract, and all sorts of so-called intestinal antiseptics, all with- out avail. The first step of value is to omit cow’s milk absolutely from the diet, the writer’s experience having convinced him that milk is in- admissible in every case whether in the form of skimmed, evaporated, fat-free, protein, or dried milk. During the past year he has used in 10 cases a synthetic milk which promises well. It is prepared by the Walker Gordon Laboratory according to the following formula: Casein 4 per cent. Sugar 4 “ Starch 6 “ One quart is usually ordered, and to this 20 grains of calcium chlorid is added. In addition to this the child is given the usual diet for the age inclusive of starches, but with perhaps a lessened amount of green vege- tables and with the omission of raw fruit temporarily with the exception of CELIAC DISEASE 265 ripe banana.1 The giving of orange juice should always be attempted even though the amounts are small. Occasionally a child will not take the synthetic milk. In such instances it is necessary to establish the child on a milk-free diet. Those who take the casein milk thrive much better than others. In providing this we give nitrogen, calcium, and soluble and insoluble carbohydrates, and thus establish a nutritional foundation, which is most valuable. No trouble has been experienced in giving starch if fresh milk is omitted. Another measure which we believe has a future is the use of the ab- dominal support. For the past three or four years the writer has used for this purpose some form of belt, chiefly those types advocated by Aaron and Bassler. During the past year the universal supporter (Figs. 142- 144) of Nicholson has been used for patients over two years of age. The results with this were so satisfactory in one case (p. 802) that the appli- ance seems highly worthy of a wider use. This support, however, is not applicable for very young children. In every case of celiac disease with enlarged abdomen some form of support is of undoubted assistance. When the patient has recovered, several months will be required before he learns or relearns to walk. Still has reported a case in which a child did not walk until he was six years old. The usual muscle stimulants, among which massage is of foremost value, will help to restore the muscles in these cases. Johnson2 has suggested that celiac disease represents a true milk allergy. We agree with him that the clinical observations would indicate an allergy to a marked degree. It is generally accepted that although the positive skin test usually is lacking in these cases, this test is not the last criterion of protein sensitization. A vast amount remains to be learned on this subject regarding degrees of sensitization. It has appeared that imperfect metabolism of fat with the formation of fatty acids may be pro- ductive of toxic agents inducing temporary dysfunction. That such may be the case and that whatever injury is produced simply relates to function is shown by the health and vigor of the children who recover. Illustrative Cases.—Case 1.—A child who had been through the hands of a half- dozen or more of the best pediatrists in the country showed not a particle of improve- ment until the synthetic milk was instituted and the fresh cow’s milk in every form eliminated. Case 2.—A typical case of celiac disease with a satisfactory outcome is the following: S. McG., a boy three years and nine months old, had been ill from the twelfth month with persistent gastro-intestinal indigestion. About six months previous to coming under observation he had undergone operation for Pott’s disease by Dr. Russell Hibbs, of New York City. At that time the boy’s weight was 21 pounds, 11 ounces, and he showed every characteristic of celiac disease; small flabby muscles, a greatly enlarged abdomen, inability to walk, and characteristic stools. Cow’s milk including protein milk had been given in some form by the various pediatrists who had attended him, the dietetic methods varying in other respects. A new diet was given consisting of 1 quart of the synthetic milk daily and an ordinary allowance of starches, meat, and vegetables. As soon as the cow’s milk was discontinued the stools became dark and formed and 1 A few years ago Dr. Sidney Haas, of New York, called the writer’s attention to the use of banana in celiac cases, and a free use of this fruit has since verified the state- ments made as to its desirability. 2 New York State Journal of Medicine, Chronic Intestinal Indigestion in Children. 266 THE PRACTICE OF PEDIATRICS lost the characteristic sour fetid odor and greasy appearance. At the end of the year the boy weighed 30 pounds, 5 ounces, and although 3 inches under height, he was well in all respects, walking, running, and playing with his brothers and sisters. The abdomen, however, still remained large. THE INTESTINAL INFANTILISM OF HERTER Notwithstanding the great amount of scientific work accomplished by Christian A. Herter, it seems likely that his name will be perpetuated in connection with the condition of intestinal infantilism more than by any other work that he did, for he described a condition that was never before carefully studied and thus established it as a distinct disease with characteristic symptoms, intestinal flora, and changes in the urine (Free- man1). In this disease there is an arrested physical development, the child is usually well formed, but does not grow and does not gain in weight. A female patient at seven and one-half years of age weighed 20 pounds and was 34| inches tall. No growth had taken place since she was two years old. A description of this child covers the symptomatology in all. The mental development was normal, the patient could read and write. In contrast to the small stature there was a marked enlargement of the abdo- men. The patient was of low resistance—she tired readily and was peevish and unhappy. She had an enormous appetite and demanded food about five times a day. The stools were large and fatty in appearance and contained a large amount of fat and fatty acids. In Herter’s infantilism frequent attacks of diarrhea are the rule. The urine shows an excess of putrefactive products of intestinal origin; the indican and phenol compounds are present. The bacterial flora of the intestinal tract, according to Herter,2 comprise Gram-positive organisms of the Bacillus bifidus type, B. infantilis type, and cocco-bacillary forms. There is a marked absence of Gram-negative bacilli in the stools. Infants of this type are very discouraging patients. No pronounced improvement is to be expected from any line of treatment. Milk, rare meat and poultry, and cereals, such as oatmeal and the wheat derivatives, constitute the basis of the diet. Freeman feels that he has observed benefit from the use of extract of pancreas, 3 grains three times daily in the form of an enteric pill. The attempt to implant a Gram-negative flora in the alimentary tract should be made. Cultures of Bacillus acidophilus, B. coli, and of B. bulgaricus may be given. INCONTINENCE OF FECES Incontinence of feces is a normal condition during infancy, control being established without training during the second year or earlier. In well-trained infants we have seen the bowel function under perfect con- trol at the third month. This is, however, unusual. With a very little teaching it may be accomplished at the sixth month. Incontinence of feces in older children occurs during acute inflammatory conditions, par- 1 Jour. Amer. Med. Assoc., vol. ii, pp. 329-332. 2 Herter’s Infantilism, Macmillan Co., 1908. CONSTIPATION 267 ticularly when the colon is the seat of the lesion. Incontinence may also occur in asthenic states, as in grave pneumonia, in typhoid fever, and in the more severe types of the exanthemata; and it may occur accidentally as the result of fright, shock, or severe straining. It may result from spinal cord disease or injury, and is sometimes due to spina bifida, in which event the fecal incontinence may be compared to incontinence of the urine. We have seen 6 such cases. In 2 the condition had existed for months. Incontinence of feces, as a condition independent of early infancy and illness, is of exceedingly unusual occurrence. Of 5 patients, 2 were boys, one four and the other seven years of age. In these 2 the condition had persisted for months. The desire for an evacuation came with great urgency and was uncontrollable. In 2 other cases there was occasional incontinence due to a relaxed sphincter, probably produced by frequent irrigations. These responded to the treatment outlined below. In the fifth case there was no response to any treatment instituted. The patient was a boy six and three-quarter years of age, and had suffered from the incontinence for a year and two months. He was under treatment for two weeks; no improvement resulted, and he passed from observation. Treatment.—The treatment consisted in the removal of green vege- tables and fruit from the diet, allowing only a small amount of starches, such as bread, potato, and cereals. Eggs, meat, skimmed milk, junket, custard, etc., were given freely. The medicine comprised 15 drops of the tincture of the muriate of iron in glycerin and water, given every four hours, with 1 grain of Dover’s powder and 20 grains of subnitrate of bismuth given three times daily. Cases which do not respond promptly to diet and medication should have the advantage of surgical procedures. CONSTIPATION Deficient fat content in the milk of young infants, ancl insufficient solid food in the diet of children over one year of age, probably are re- sponsible for a majority of the cases of constipation. The digestive organs demand not only elements for assimilation, but a certain amount of food residue to act as a stimulus to perfectly normal musculature. The results of the absence of a fair amount of this food residue in the diet are most apparent in children between the first and third years, who receive over a quart of milk daily, administered in frequent instalments, and from force of parental habit or perverted desire on their own part are deprived of such important dietetic ingredients as cereals, vegetables, and fruit. Such children are almost invariably sufferers from chronic constipation. The cases commonly ascribed to deficient secretion on the part of the intestinal glands and liver are also frequently of dietetic origin. Mechanical defects and abnormalities may be entirely responsible for the most obstinate constipation. Localized proctitis, fissures and hemorrhoids, and sphincter spasm may be important causative factors. Congenital narrowing of the gut, elongated sigmoid (Fig. 45), prolapse of the colon (Fig. 55), hernia, and congenital dilatation of the colon (Hirschsprung’s disease) deserve to be borne in mind in this connection. As our experience with this disorder increases we are more and more 268 THE PRACTICE OF PEDIATRICS impressed with the importance of disturbed intestinal mechanics as a direct or accessory cause of constipation in children of all ages. Before instituting treatment of any nature it is necessary to know that no mechanical cause exists. Fig. 54.—Dilatation and stenosis of the rectum. (The appendix is outlined.) Figure 54 represents a female child five years of age showing extreme retention in the rectum twenty-seven hours after a bismuth meal. The child came for malnutrition and with the diagnosis of acidosis. In very early life she was supposed to have had pylorospasm. There had been much trouble in feeding her up to time she was three years of age; and she had had frequent vomiting seizures with high fever—103° to 105° F. During her fourth year she had but two seizures of the fever and vomiting. This patient has but recently come under observation. Stretching the anal sphincter, abdominal massage, and a diet directed to relieve her constipation (p. 273) will be fol- lowed out in this case. Bowel Evacuation Necessary.—In order to keep the infant or young child in good physical condition one free evacuation of the bowels is required once in twenty-four hours. While two or three evacuations daily may be desirable, this number is not absolutely necessary. When there are more than four passages in twenty-four hours the inference is that something is wrong with the intestinal tract. This, however, may not be of such a nature as to require radical means for its correction. Thus, CONSTIPATION 269 many nursing babies who are supplied with a high-fat breast milk, may have several thin greenish stools in twenty-four hours, and in spite of the condition thrive satisfactorily. It is well in these cases to attempt to reduce the fat in the breast milk by measures suggested elsewhere, but by no means should the nursing be interdicted if the baby is making a reason- able gain in weight. The proof of successful nursing is a thriving child, not the character of the stool. The habit of an evacuation at a certain time each day is one of the most important preventives of constipation in an infant. There should be a standing order in every household to the effect that the child is never to be put to bed for the night unless the Fig. 55.—Prolapsed colon and anal sphincter spasm. The patient was a girl six years of age with a typical V-shaped ptosed colon and dilated rectum. The story was that of recurrent attacks of vomiting every six weeks. Enemata for the chronic con- stipation had been given daily since birth. Retention of the opaque meal was observed forty-eight hours after injection of the material. This child had also a moderate stom- ach ptosis. The anal sphincter was stretched under anesthesia. An Aaron belt with shelf was applied and the diet regulated. No attacks of vomiting occurred subsequently during observation extending over two and a half years. bowels have moved during the preceding twenty-four hours. Either a simple soap and water enema or a small glycerin suppository may be employed. The enema is preferred, from 4 to 8 ounces of the soap-water being used. The suppository is to be used only when, for any good reason, the enema is not available. Placing the child at stool immediately after the morning bottle is one of the means of establishing the habit of an evacuation at a definite time each day. The child soon appreciates the reason for this practice and acts accordingly. This procedure may be begun when the child is five or six months of age. Defective bowel evacuation in infants and young children is a form of 270 THE PRACTICE OF PEDIATRICS constipation very apt to be overlooked, and for this reason it is put under an independent heading. As long as an evacuation takes place daily it is supposed to be sufficient. Even though a passage takes place daily and voluntarily, if it is dry and comes away in pieces or in hard balls, or is firmly formed without the moist surfaces caused by the presence of mucus and water, it is practically certain that the evacuation is not complete and that fecal matter is retained in the intestine. This type of constipation is often associated with ptosis of the stomach (p. 221) and anal sphincter spasm. (See Fig. 55.) The ptosed stomach always empties very slowly and the absorption of the water from the intestinal contents is then more than normally complete. This may occur at any age, and when the con- dition persists, an intestinal toxemia may result with the manifestations referred to under Indigestion (p. 232). The same methods of treat- ment are to be followed as suggested for constipation at the various ages of infancy and childhood. Constipation in Nurslings.-—There are many nursing infants who are thriving and well in every respect, except that they are constipated. Bowel evacuation is greatly delayed or does not occur without aid. Our first step in the management of these cases is to examine into the daily life and habits of the mother. A factor in the etiology of constipation in the infant is constipation in the mother. Treatment of the mother will often relieve the child. If, however, the constipation in the mother is not relieved, the subsequent treatment directed toward the child will be much less effective. Nursing women who drink a great deal of tea are apt to be constipated, and their infants are similarly affected. The nurslings of mothers who lead indolent lives, taking but little exercise, are likewise sufferers from constipation. Treatment of the Mother.—Errors in the mother’s diet and habits of life must be corrected and the scheme carried out which is recommended under Maternal Nursing (p. 42). When a proper regime for the mother has been established, the breast milk should be examined. While high protein may contribute to con- stipation, this factor is rarely a cause. Low fat, from 1.5 to 2.5 per cent., with normal protein is much oftener found to be present. Often in such cases the fat in the mother’s milk may be increased, if only temporarily, by the use of some form of alcohol, given with the meals. Wine, beer, ale, porter, or the liquid malt preparations may be given, the mother being allowed to make her own selection according to her taste. The free eating of red meats also increases the fat in the milk. Several years ago a series of observations were made in the New York Infant Asylum relating to the effects of diet on breast milk. It was found that in some cases the fat could be increased from 1 to 2 per cent, by the addition of alcohol to the mother’s diet. The value of many of the various galactagogues on the market depends, in all probability, upon the alcohol which they contain. Treatment of the Child.—A very tight sphincter is the cause of con- stipation in a small proportion of nurslings; and before beginning other treatment in such cases the sphincter should be stretched by passing a protected index-finger into the rectum. As an aid to nutrition and as a laxative a valuable addition to the diet of the constipated breast-fed CONSTIPATION 271 infant, when the mother’s milk is found weak in fat, is cow’s milk cream, i to 1 teaspoonful of which may be given before every second nursing or before every nursing, according to the age of the child and the capacity for fat digestion. Children during the early months of life take pure cod- liver oil readily, and oil, like cream, may serve the double function of a food and a laxative. Establishing by careful instruction the habit of an evacuation of the bowels at a certain time every day is a valuable measure. Drugs.—Drug giving is rarely necessary in treating very young chil- dren and should be resorted to only when other measures fail. In case drugs are necessary, those most useful ordinarily are the preparations of cascara sagrada. The aromatic fluidextract is palatable and may be given in sufficient doses to be effective once or twdce daily. The milk of magnesia with equal parts of the aromatic syrup of rhubarb, given in doses of from 1 to 3 teaspoonfuls daily, is an agreeable and usually an effective combination. The liquid petrolatum, in 1- to 4-dram doses, acting as a lubricant, often gives surprisingly good results. Enemata and Suppositories.—The use of water enemata and sup- positories is not to be advised as a routine measure. The habit of de- pending upon them is readily established, the bowel, by their frequent use, becomes insensitive to stimulation, and in a few weeks they fail to act. Many mothers are thrown into a state of great distress when this stage is reached. When the stool is dry and hard and is passed with difficulty, the injection of 2 ounces of warm sweet oil at bedtime is of advantage. This is not intended to produce an immediate evacuation, but rather to act as a lubricant for the evacuation expected the following morning. Malted Foods.—It is elsewhere advised that the nursing baby be given one bottle feeding daily. The malted proprietary foods are dis- tinctly laxative to many children. When, in a nursing infant, a condition of constipation exists which is not relieved by careful regulation of the mother’s diet, one feeding of malted milk daily, in the strength of 1 tea- spoonful to an ounce of water, may be prescribed. Some children will not take malted milk of this strength, as the sweet taste is objectionable. In such cases it may be given weaker at the beginning, or it may be given in a milk mixture suitable to the age of the child. When it is used in this way there should be no addition of sugar. Malted milk or Mellin’s food may be used in a quantity equal to that of the sugar previously employed in the formula. Massage is a most valuable means of treatment of the constipation of older children, but for nurslings and the bottle fed of tender age, on account of the restlessness and crying, it is not always practicable, and to be effective should be given only by those skilled in its use. There- fore, unless the case is an extreme one, and all other measures have failed, massage is not to be employed in treating the very young. Constipation in the Bottle Fed.—Before undertaking the treatment of constipation in any infant the rectum should be examined to determine the presence or absence of sphincter spasm (p. 276). In the bottle fed inactivity of the bowel is more easily managed than in the nursling, because, in dealing with the former, we are in a better position to adapt the food to the child’s digestive peculiarities. As a rule, constipated bottle 272 THE PRACTICE OF PEDIATRICS babies should have a reasonably high fat—3.5 to 4 per cent.—and sugar up to at least 7 per cent. This rule, however, is open to exceptions; a few of the most obstinate cases of constipation that have come under our care have been fed on a very high fat, the constipation being due to fat indigestion. It is extremely rare to find a child who can digest day after day a milk mixture containing more than 4 per cent, of cow’s milk fat. The Protein.—Cow’s milk casein, although probably the most fruit- ful factor in causing constipation in bottle-fed babies, nevertheless is necessary for the child’s nutrition. A considerable reduction, such as may be obtained by giving a mixture of cream, sugar, and water, may relieve the constipation, but the child thus fed will suffer from a nutri- tional standpoint, and instead of being constipated may become athreptic, which is much worse. In not a few instances malnutrition has been observed as the result from cutting down the protein in the effort to relieve constipation. The child’s growth and development must never be held subservient to anything else. A child under six months of age will not thrive satis- factorily on less than 1 per cent, of protein as found in cow’s milk. He is entitled to at least 1.5 per cent., and thrives best when this amount is given. The relief of the constipation can in almost every instance be accomplished by other means than a too great reduction in the protein— the most essential nutritive element in the infant’s food. Milk given constipated infants should always be raw, as cooking increases its constipating tendency. Laxative Agents in the Food.—The simplest means of treating con- stipation in the bottle fed is by the employment of a laxative agent in the food, and when such an agent adds to its nutritive value, it serves a double purpose. Instead of water as a diluent, oatmeal-water No. 1 (p. 94) may be employed. The malted proprietary foods, such as Mellin’s food and malted milk, are laxative to most children. Mellin’s food is composed largely of dextrose and maltose, which are laxative sugars, and therefore may be used in place of sugar-of-milk or cane-sugar in the food mixture, for the purpose of relieving constipation. The presence of potassium carbonate in dextrose and maltose combinations also probably increases their laxative property. In some instances we substitute a feeding of malted milk with from 4 to 8 ounces of water once daily for the regular milk food, the quantity and strength depending, of course, upon the age of the child. Drugs and Local Measures.—Dietetic measures should always be tried before drugs are resorted to. One or 2 teaspoonfuls of milk of mag- nesia in one bottle daily may be recommended as a temporary expedient in some cases. The magnesia may be of service until the condition is controlled by the diet. The aromatic fluidextract of cascara, in doses of from 15 drops to 1 dram, may be tried if success does not follow the use of the magnesia. Water enemata and suppositories should be used only as temporary measures. Orange juice, 2 teaspoonfuls twice daily before feedings, is worthy of trial, and is of antiscorbutic value for children artifically fed. Sweet oil and the pure cod-liver oil may be also used in doses from 30 CONSTIPATION 273 drops to 2 drams, three times daily, after feedings. Oils produce bene- ficial effects not only as laxatives but also as aids to nutrition. Acting purely as a lubricant, liquid petrolatum in dosage of 2 drams to \ ounce, once daily after the evening meal, is of much service in many cases. Oil Injections.—In case the stool remains hard and dry in spite of a trial of the above suggestions, an injection of 2 ounces of warm sweet oil may be given at bedtime every night, not with a view to inducing a passage at the time, but as a lubricant to the parts and as a solvent of the hard fecal masses. Constipation in Older Children.—Etiology.—Probably the most potent dietetic factor in causing constipation in children of the “runabout” age is the use of abundant milk, crackers, and dry bread-stuffs. Par- ticularly is this apt to be the case if the milk is boiled. Constipation at this age may also be occasioned by too great concentration of the food, insufficient volume being furnished to produce copious evacuations. Local Causes.—In a great majority of children the freer feeding fol- lowing weaning from the breast and bottle relieves the tendency to con- stipation from which many suffer during the earlier months of life. In a small percentage of cases, however, such relief is not furnished, and the child will require the attention of a physician. In making the physical examination of a case of this nature, special care should be directed toward the examination of the rectum, in order that local causes, such as fissures, hemorrhoids, or sphincter spasm may be eliminated. If fissures are pres- ent, the child will use every effort to prevent a bowel movement. Mechanical Obstruction.—Elongation of the sigmoid (p. 256), ptosis of the colon and cecum (p. 259) play a part hitherto unsuspected as the causation of constipation. Recently much light has been thrown on many difficult and obstinate cases by the use of the Roentgen ray. Mechanics play an immediate role in constipation, as will be appreciated by referring to Fig. 48. The long sigmoid loop is an important factor in causing constipation, and even after infancy anal sphincter spasm may be an im- portant etiologic factor. Regular Habits.—As a rule, children who are presented for treat- ment after the second year have not had the benefit of carefully regu- lated habits of life, so that our first step is to correct bad habits that may have a bearing on the condition, and to teach good habits. The desirability of establishing in the child the habit of a bowel evacuation at a certain definite time every day should be impressed upon the mother or nurse. In order to bring this about an attempt should be made to induce a movement of the bowels by voluntary effort every morning after breakfast. Not a few children are too busy, too active in their play, to respond to the call of nature when it comes, and if it can be repressed, they say nothing about it. If a certain time of the day is selected for the evacuation, and if the child is required to remain at stool until it occurs naturally, or by means of a suppository after fifteen minutes have elapsed, much is accomplished by this means alone toward establishing the normal habit. Diet.—Ultimately, much may be accomplished in these cases by diet. Foods other than milk may after infancy be given, so that a high-protein milk, rich in casein, is not necessary. As it is desirable to continue the 274 THE PRACTICE OF PEDIATRICS use of milk at this age, the following combination of top milk and water may be used instead of plain milk: A quart bottle of milk may be allowed to stand at a temperature between 40° and 50° F. for five hours, after which the top 10 ounces are to be removed with a Chapin dipper. (See Fig. 6, p. 70.) The 10 ounces of top milk may then be mixed with 20 ounces of oatmeal gruel or plain boiled water and given as a drink. The giving of high-fat mixtures in constipation is sometimes overdone even in feeding older children. We seldom find a child five years of age who can digest day after day a milk or cream mixture containong over 4 per cent, of fat. Attacks of acute indigestion and faulty nutrition are very apt to result when too high a fat is persistently given. In not a few instances grave malnutrition results from an attempt to relieve the con- stipation by high-fat feeding. It must also be remembered that high-fat mixtures, if given to children of any age, may produce constipation, with hard, very light colored, and foul-smelling stools. By using the top milk, diluted, we give a sufficient amount of fat and relieve the constipation by removing a considerable percentage of the casein, the usual constipating element, the percentage of which in the 30 ounces of food, above referred to, is but one-third that in whole milk. Of course, the nutritive value of the dilution is less than that of full milk, but the child is now at an age when protein can be given in other forms than in the milk. Diet After the Second Year.—White wheaten bread, wheaten flour crackers, with full raw milk should form no part of the dietary of these patients. It is best to give to parents of children we are treating for con- stipation a list of permissible articles of food from which suitable meals may be prepared. The following articles of diet may be allowed: Animal broths, purges of peas, beans, and lentils. Rare roast beef. Rare steak. Hashed chicken. Lamb chops. Soft-boiled eggs. Green vegetables, such as: Peas. String beans. Spinach. Asparagus. Strained stewed tomatoes. Cauliflower, mashed. Cereals, as follows (each cooked for three hours): Cracked wheat. Oatmeal. Hominy. Cornmeal. The cereals may be served with a small amount of milk and sugar or, better, with butter and sugar. Bran biscuits. Oatmeal crackers. Graham wafers. Zwieback. Whole wheaten bread. Desserts: Stewed rhubarb. Stewed or baked apple. Stewed prunes. Custard. Cornstarch. Plain vanilla ice-cream. Junket. CONSTIPATION 275 Malted milk may be given as a drink, 6 teaspoonfuls of malted milk in 8 ounces of hot water being given once or twice daily. An agreeable change in the taste of the malted milk may be made by the addition of a teaspoonful of cocoa. If milk is given as a drink, the top 10 ounces from a quart bottle should be used as described above, mixed with 20 ounces of boiled water or oatmeal water. A child in fair health after the second year usually thrives best on three meals daily. If he is delicate, or if a fourth meal does not interfere with the appetite for the other meals, it may be allowed. The extra meal, however, should be light, and is best given between 2 and 3 o’clock in the afternoon. For a child suffering from constipation this meal may consist of a cup of broth with a Graham or oatmeal cracker. Orange juice or a scraped raw apple may also be given at this time. When only three meals are allowed, the orange juice or scraped apple should be given in the after- noon about two hours before the evening meal. Six ounces of prune juice will be found very useful. The giving of the fruit juice or the apple on an empty stomach is a valuable aid in relieving chronic constipation. These patients should also be encouraged to eat plenty of butter. The use of olive oil internally is of as much service here as in treating bottle or nursing babies. From 2 to 3 teaspoonfuls are to be given after each meal. Oil is usually well borne by the stomach; in fact, many children become very fond of it. Inasmuch as it is more of a food than a medicine, its use may be continued for months if necessary. Diet After the Fifth Year.—Permissible articles for a constipated child of from five to ten years of age include those mentioned above, with the addition of dates, figs, raw and cooked fruits, baked and stewed pota- toes, meats, baked and broiled poultry, and fish. The latter should be served plain, without sauce. Plain puddings may also be allowed. One or two raw apples, an orange, or a large peach or pear should be given every afternoon. It is not promised that in a case of chronic constipation the above diet will at once produce normal bowel movement. The diet must be continued for weeks in some cases before marked benefit will be observed; in others the results are very prompt and satisfactory. Local Measures.—Enemata and suppositories will be necessary at first until the habit of an evacuation of the bowels at a certain time every day is established. Such measures, however, should be continued but a very short time. Drugs may be of temporary service. The cascara preparations are the best for this condition. If the child can swallow a pill or a tablet, the drug may be given in this form. The 1-grain tablets of cascara may be ordered, and the nurse instructed to give from one to three or four at bedtime. If the drug has been properly prepared from the well-seasoned bark, a reasonable dose will occasion no griping, and the amount given on succeeding nights may be diminished instead of increased, as is often necessary with many other laxatives. A most satisfactory form of medi- cation has been the following combination: 1$. Sodii bicarbonatis 3ij Syr. rhei aromatici, Fluidext. cascarae sagradae aromatic* aa 5'j M. Sig.—\ to 1 teaspoonful after each meal. 276 THE PRACTICE OF PEDIATRICS After the diet and habits of life have been arranged the mother or nurse should be instructed to give the prescription three times daily after meals in sufficient amount to produce at least one free evacuation daily. The mixture is very pleasant to the taste and is well taken. Ac its ad- ministration is continued, less will be required, but it is to be insisted upon that the laxative be given three times daily, even though the dosage be reduced to 3 drops at a time. There is always a temptation on the part of those in charge of the patient to give one large dose at bedtime. The results are not as satisfactory when this is done. In a very large number of cases we have been able, with intelligent home co-operation, to dis- continue the medication entirely after a month or two. Another laxative of value is a combination of 1 to 1| grains of phenol- phthalein in a tablet with chocolate. One to three such tablets may be given daily. Castor oil, calomel, or podophyllin should never be given without other indications than simple constipation. In the cases in which the stools are soft, but difficult of passage because of deficient peristalsis, the tinctures of nux vomica and belladonna may be given with benefit if con- tinued for a considerable time. A child three years of age may be given 3 drops of the tincture of nux vomica and 2 drops of the tincture of bella- donna three times daily in tablet, capsule, or liquid form. The constipa- tion which accompanies mucous colitis is referred to under that heading. Liquid petrolatum may also be used for these patients. A large dose may be required at first—perhaps 1 or 2 ounces at bedtime. Treatment of Obstinate Constipation.—Children who resist the above method of treatment after several months’ trial may be classed with those who have some considerable intestinal anomaly—usually an elongated and often a displaced sigmoid (p. 256). For these, daily abdominal massage by a skilled person, together with the diet suggested, and the internal use of liquid petrolatum will prove effective. Conditions impeding or preventing normal evacuation of the bowels may be either congenital—due to a malformation of some portion of the intestinal tract—or they may be acquired. Congenital malformation may be found in any portion of the tract, but exists most frequently at or near the outlet, or in the region of the duo- denum. According to Silverman 42 per cent, of the cases of congenital malformation involve the duodenum. Obstruction at the outlet of the bowel may be due to an imperforate anus, or the absence of, or atresia of, the lower portion of the rectum. The treatment of this deformity is surgical. The most common cause of acquired obstruction is intussusception (p. 277). Peritonitis, both acute and chronic, may cause a cessation of bowel action. Tuberculous peritonitis, through the formation of fibrinous bands and adhesions, may cause sufficient constriction of the gut to pre- vent the passage of the intestinal contents. In such cases, also, relief is best furnished by surgical measures. Acute infective peritonitis (p. 291), producing a complete cessation INTESTINAL OBSTRUCTION INTESTINAL OBSTRUCTION 277 of peristalsis, due to paralytic ileus, acts indirectly as a means of preventing the normal passage of the bowel contents. The infection is usually sec- ondary. Operative procedures may be attempted, but all our cases have been fatal. Two underwent operation, as it was feared there might be an intussusception or a volvulus. In one case peritonitis followed pneu- monia, the infection being due to the pneumococcus. Strangulated hernia is a condition by no means difficult of diagnosis and demands prompt surgical relief. Intra-abdominal tumors, such as sarcoma of the kidney and hydro- nephrosis, may cause obstruction through pressure on the intestine. Illustrative Cases.—Fecal impaction was found in 2 cases of intestinal obstruc- tion seen in consultation. There had been prolonged constipation with insufficient evacuations, owing to neglect on the part of the attendants. The duration of this condition it is impossible to state, as the children were permitted to go to the toilet alone, and as both were under five years of age, but little dependence could be placed upon their testimony. In both cases enemata and cathartics had been tried in vain. There was vomiting and slight abdominal distention. There was no fever and no marked tenderness on pressure. In the writer’s opinion the vomiting was due chiefly to the medication, for it ceased when drugs were discontinued. Both children responded to massage and injections of molasses and water. Eight ounces of molasses and 8 ounces of water were introduced by means of a rectal tube at intervals of four hours. One case was relieved after the second injection, the other after the fourth. Massage was early brought into use. This was given for thirty minutes and repeated after an interval of ninety minutes. The interrupted massage was continued until an evacuation occurred. An unusual case of intestinal obstruction was seen in a wretched, premature infant, five months of age, weighing about 7 pounds. The child had a congenital heart lesion and deformities of the ears. He was suddenly taken ill with vomiting, and the passage from the bowel of pale mucus streaked with blood. No tumor could be felt, but a diagnosis of intussusception was made and the abdomen opened. At the site of the obstruction was a Meckel’s diverticulum which had twisted the gut so as to prevent the passage of gas or intestinal contents. Paralytic Ileus Two infants under one year of age, ill with severe intestinal toxemia, developed intestinal obstruction with marked abdominal distention. Exploratory abdominal incision in one and autopsy on the other failed to show any structural abnormality. Intussusception of the bowel consists of a prolapse—an invagination —of a portion of the intestine into an immediately adjoining portion. Types.—While certain portions of the intestine are particularly liable to be involved, the invagination may take place in any portion of the gut. Thus the small intestine may be the part involved—the enteric form. The colon alone may be involved—the colic type. By far the most common form is the prolapse of the cecum, and more or less of the ileum into the colon, the valve forming the apex of the tumor. This is known as the ileocecal type. Invagination Found at Autopsy.—At autopsy it is of most common occurrence to find invagination of the small intestine. The writer has repeatedly seen 6 to 8 invaginations in one subject. They occur at death, and are of no significance. It is unusual to find more than 4 or 5 inches of the gut involved. Etiology.—The cause of the intussusception in the great majority of cases is unknown. Various theories have been advanced from time to time, none of which deserves mentioning. Occasionally local causes will Intussusception 278 THE PRACTICE OF PEDIATRICS explain the condition. In one case Meckel’s diverticulum caused the intussusception. In another there was a persistent incomplete reducible invagination of the transverse and descending colon into the sigmoid. It was impossible to keep the parts in the normal position, and laparotomy was resorted to in order to learn the cause of the prolapse. The entire colon was found displaced, the hepatic flexure being bound to the ab- dominal wall by a firm adhesion \ inch above the umbilicus. This caused a displacement downward of the transverse and descending colon, which underwent invagination. A case at the Babies’ Hospital showed that the invagination had taken place at the site of a large and thickened Peyer’s patch in the lower ileum. Here, evidently, the gut was more resistant, and the portion above, during active peristalsis, slipped into the less motile section. It is peculiar that nearly all the cases occur in well-nourished, vigor- ous, breast-fed babies. Age.—The age incidence is striking. The majority of the cases occur between the third and ninth months of life. Our youngest patient was ten days old. Holt’s statistics of 358 collected cases are as follows: 28 cases under 4 months \ 113 “ “ 4 to 6 months 71 “ “ 7 to 9 “ 18 cases from 10 to 12 months 32 “ “ 1 to 2 years 96 “ “ 2 to 10 “ Symptoms.—The onset is usually sudden, with evidence of pain and vomiting. A further early and very important sign is the marked pros- tration, which is much more pronounced than in an ordinary gastro- enteric disease. The child in a few hours may look very ill. There is cyanosis, and the pulse is rapid and small. This symptom-complex was noted in several cases. The vomiting, which is very active, is repeated at fairly short intervals, and after the stomach is emptied bile-stained mucus is ejected with much straining. Medication, food, and water are ejected as soon as they reach the stomach. There is evident tenesmus; the child strains, and at first passes normal bowel contents, followed by bile-stained mucus, and later clear mucus streaked with blood—a most reliable diag- nostic sign. Blood is not always present. In some instances only white, tenacious mucus is passed or removed on the examining finger. On the other hand, the blood may be present in large amount, constituting a very definite hemorrhage. The prostration, urgent at the beginning, increases, and the patient may die of shock before operation is attempted. The Presence of Tumor.—If the case is seen early, a sausage-shaped tumor may be felt, or the rounded apex of the tumor may be felt by rectal examination if the descending colon is involved. If the patient is not seen until several hours or days have elapsed, the accumulation of gas in the intestines renders the palpation of a tumor impossible. Occasionally a case is seen in which the onset is more gradual, in which gas and bile-stained mucus will be passed for a day or two. This indicates that the invagination is not sufficient to close the lumen of the gut. Finally, only blood and mucus are passed and the obstruction is complete. Three or four days may be required to bring this about. Vom- iting is a less pronounced symptom in these cases of gradual development. Stercoraceous vomiting does not occur in young infants. INTESTINAL OBSTRUCTION 279 The Temperature.—The temperature range is of no significance. In many cases the temperature is never above 100° F. Diagnosis.—There is no satisfactory excuse for so many failures in diagnosing intussusception in infants. The reason for the failure to appreciate the condition is because physicians too readily interpret active vomiting, with green, mucous, and bloody stools, as significant of gastro- enteric intoxication. Distinguishing features of intussusception are: Vomiting, sudden and urgent by a previously well infant, who may be breast fed; shock and collapse out of proportion in severity to the other symptoms; the passage of clear, mucous stools streaked with blood, together with the presence of pain of a paroxysmal nature, the absence of the passage of flatus, and the sudden distention of the abdomen. The presence of a tumor which can be felt either by abdominal pal- pation or in the rectum occurs in perhaps 80 per cent, of the cases. In cases of ileocecal intussusception the tumor may be difficult to map out, particularly if there is much distention of the abdomen. Under these circumstances anesthesia should be used in suspicious cases. Rectal examination is always a valuable aid and should never be neglected. Illustrative Case.—A breast-fed infant three weeks old suddenly terminated a diarrhea of two days’ duration and in the next thirty-six hours vomited bile-stained fluid, developed extreme abdominal distention and rigidity, and failed to respond to enemata. The diagnosis of intussusception was made by several observers. Opera- tion, however, disclosed a fatal spreading peritonitis with much exudate containing Streptococcus hemolyticus, but revealed no obstruction or initial focus of inflammation in the bowel. Extreme enteroparesis had simulated obstruction of the intestine and the absence of a visibly infected umbilicus left the source of the infection (which may have been pulmonary) in doubt. In this instance it is noteworthy that a localized abdominal tumor was not felt. Vomiting was not persistent and bloody mucus appeared only after rectal examination and was perhaps due to slight trauma of the mucosa. The prognosis in the immediate, complete type of obstruction depends largely upon the time of making the diagnosis and the promptness of operative procedures. The chance for recovery from operation decreases rapidly with each succeeding day. It is impossible to give statistics of value. It is safe to say that over 50 per cent, of these cases are curable by some means if they are diagnosed early. The high mortality—50 to 80 per cent.—is due to two conditions: the tender age of the patients and the fact that the cases seen in con- sultation and those seen in children’s hospitals usually have been treated for something other than intussusception. Sometimes such treatment has been continued for several days. By the time those cases reach the hands of the surgeon there may be extensive adhesions, gangrene of the involved portion of the intestine, and an exhausted child to deal with. Treatment.—Reduction by Water-pressure.—This means is only of use when the intussusception has involved only the large intestine. In the ileocecal type operation at the earliest moment is the only resource. A well-oiled catheter, No. 18 American, or a small rectal tube, is attached to the small hard-rubber tip of a fountain-syringe. Two quarts of a normal salt solution are placed in the bag, which is hung at an elevation of 4 feet above the child’s body. The colon, or that part of it below the 280 THE PRACTICE OF PEDIATRICS intussusception, is slowly filled with the warm salt solution. A small wet towel is tightly wrapped around the catheter, and fairly strong pressure is made at the anus by an assistant, in order to prevent the escape of the fluid. With the child on his back, with both hands free, the buttocks are elevated on a pillow or bed-pan at a plane 10 inches above the shoulders. In the cases in which the tumor is palpable, an attempt is made, by gentle abdominal manipulation, to reduce the intussusception. This in 2 cases the writer has succeeded in doing. Prolonged and repeated attempts at reduction should not be practised. Fig. 56.—Ileocecal intussusception (Kerley and LeWald). Illustrative Cases.—Case 1.—A child, two and one-half years of age, was brought at midnight with a history of a severe attack of colic about 9 o’clock, which was fol- lowed by severe attacks of vomiting and two stools of mucus and blood. Gentle manipulation of the abdomen showed a large, sausage-shaped tumor, about 5 inches long, in the left hypochondrium, which indicated an intussusception. The tumor could not be felt by rectal examination. Water-pressure, as described above, with abdominal manipulation, reduced the intussusception in a few minutes. Case 2.■—The other patient was a baby nine months of age. The senior author saw the child in consultation after the intussusception had existed for six days. The child was comatose and in profound collapse. He was pulseless, but the heart sounds could be faintly distinguished by the aid of stethoscope. The rectal temperature was 96° F. The abdomen was greatly distended. The child had been treated for cholera infantum, although for five days nothing but white mucus tinged with blood had been passed. Palpation revealed a sausage-shaped tumor extending along the entire left side of the abdomen, which, in spite of the abdominal distention, could easily be made INTESTINAL OBSTRUCTION 281 out by firm pressure. As the child was unconscious, there was no resistance to the ex- amination. By rectal examination the projection of the involuted gut, which resembled the cervix uteri, could readily be distinguished. The condition of the child precluded all chance of surgical relief, and the writer hesitated to use water-pressure, fearing that the gut might be gangrenous and a rupture result, or that there might be adhesions sufficient to prevent reduction, and that the child might die during the manipulations. This situation was explained to the parents, who, after considerable urging, consented to a trial being made. The patient was accordingly given 1/100 grain of strychnin 1 drop of tincture of strophanthus, and 30 drops of brandy hypodermically. The water- pressure was applied in the usual way, and it was with the greatest surprise and with supreme satisfaction that the writer felt the tumor slowly give way, to be followed by an expulsion of gas and a quantity of very fetid fecal matter. A hot colon flushing at 110° F. with a normal salt solution was given a few minutes later. This was all retained, and six hours later 12 ounces more were given. Hot-water bottles and bags were'placed about the child. He had sufficiently revived in an hour after the first colon flushing to be able to swallow diluted brandy and egg-water, both of which were freely given. A rapid recovery followed. This case, to the writer, was interesting in many ways, particularly as it emphasized what we sometimes see in work among children when victory is snatched from the jaws of evident defeat—that we should never cease our efforts so long as life lasts. Case 3.—-The following notes in conjunction with Fig. 56 give briefly the record of a case terminated favorably by operation: “Male, aged sixteen months. On day of illness awrnke apparently normal, but later refused regular feeding. Castor oil and an enema administered; results unsatis- factory. Vomited during the following night. No rise in temperature; no palpable mass; no point of tenderness. Clinical diagnosis: Suspected intussusception. “Roentgen Examination.—An opaque enema disclosed site of obstruction and its cause: intussusception of the terminal ileum into the cecum. The injected column of opaque material, w hen it met the intussuscepted portion of the ileum, spread out over it in a thin layer, leaving the central filling defect in the cecum which could hardly be simulated by any other known condition (Fig. 56). “Operation.—Abdomen palpated under anesthesia; no mass felt. Due to the Roentgen diagnosis a small incision wTas made directly over the cecum. Intussusception reduced in a very short time. Recovery. “Comment.—Only a very few cases of Roentgen diagnosis of intussusception have been reported. As the Roentgen findings are so conclusive in a case of this sort, they should not be omitted with a questionable diagnosis.” Intestinal Cysts or Diverticula (Congenital) A most unusual case of intestinal obstruction was presented by a well-nourished, breast-fed child, five weeks of age, who became ill with what appeared to be intestinal indigestion. There was a slight elevation of the temperature, and the stools were green, undigested, and watery. The family physician, Dr. Walter Fleming treated the case by the usual methods. An improvement in the stool followed, but a marked degree of tympanites remained. Feces and gas were, however, passed in small amounts, and at times the abdomen was sufficiently soft to allow of free palpation. The tympanites gradually increased, and instead of being intermittent, persisted. About one week after the writer first saw the case it came under his immediate supervision in New York City. Feces and gas were passed with difficulty—occasionally there was a fairly large stool. The child was in no way apparently ill, and suffered only from the abdominal distention; when this was relieved, the baby took food well and was content. In spite of our every effort directed to relief through diet, medication, local measures to the abdomen, and colonic treatment, the tympanites gradually increased and became per- manent and extreme. The patient was sent, at about the sixth day of the writer’s observation, to the Babies’ Hospital, where all attempts at reduction of the gaseous distention were like- wise futile. An exploratory incision was then made into the abdominal wall by Dr. William A. Downes, who discovered a tumor of the cecum. An artificial anus was made in the ileum above the valve, and the tympanites was relieved; but the child died shortly from exhaustion. Postmortem examination showed just above the ileocecal valve, and within 5 cm. of it, a round, sessile cyst, 3 cm. long and 2.5 wide by 0.75 cm. high, the mucosa over it thin, stretched, congested at either side, pale on top, with dilated vessels from the base radiating over the sides and top. Immediately beyond was a second cyst, 2.5 x 2.5 cm. and only 0.25 high; close to it, almost bilocular, was a third, 2.5 x 2 and 0.75 cm. high. Contents showed mucolymph within a smooth lining. Between the mucosa 282 THE PRACTICE OF PEDIATRICS and submucosa the muscle was normal. Next to the last cyst was a part of a Peyer’s patch, mucosa congested, walls thickened and edematous. The colon was congested. The cysts or diverticula had encroached upon the lumen of the gut, and because of their proximity, formed a sufficient obstruction to preclude the passage of gas and the intestinal contents. Evidently the later growth of the cysts was quite rapid, as the obstruction caused symptoms increasing only gradually in severity, and permitted of the passage of feces until a day or two before the operation. Blackader, of Montreal, reported a case of congenital intestinal cysts, similar to the foregoing, before the American Pediatric Society in 1913. He was able to find records of but 3 other cases of congenital intes- tinal cysts in the literature. The condition, according to Gant, is not uncommon in adults; and in them the cysts are usually found in the sig- moid and colon and are looked upon as acquired. Meckel’S Diverticulum Meckel’s diverticulum, the remains of the omphalomesenteric duct, is present in 1 or 2 per cent, of all individuals and is slightly more common in the male sex. It is usually situated about a foot above the ileocecal valve and may occur as a fibrous cord or retain a patent lumen. The tip may be attached to the umbilicus or may be free. In the latter case there are usually no symptoms associated with its presence. The pathologic conditions which may be associated with Meckel’s diverticulum are: 1. Obstruction or strangulation of intestine giving the usual symptom of obstruction. 2. A patent lumen which may extrude feces, mucus, worms, or even intestine, the bowel in some cases protruding and strangulating at the umbilicus. 3. A cystic tumor containing meconium formed in the duct, obliterating it at both ends. 4. Calculi or foreign bodies resting in the lumen. 5. Malformations or excessive involution causing contraction or kinking of the gut by traction. 6. A free diverticulum which may invaginate with a subsequent ileo- cecal intussusception. 7. Volvulus. 8. Hernia. 9. Diverticulitis, of which the pathology and the signs and symptoms are analogous to those of appendicitis. The differential diagnosis from appendicitis is practically impossible. Whereas in appendicitis inflammation per se is more common than ob- struction, obstruction is more commonly associated with Meckel’s di- verticulum than a primary diverticulitis. The point of tenderness is usually a little higher and closer to the umbilicus than McBurney’s point. There may be puffiness and resistance of the abdominal wall in the same region. There is usually in the early stages very little tympanites and there may be blood in the stools or vomitus. The knowledge of the earlier existence of an umbilical fistula or other congenital malformation may help in diagnosis. Otherwise the sjmiptoms are closely identical with those of intestinal obstruction or appendicitis. The treatment is surgical. HERNIA AT THE UMBILICUS 283 Illustrative Case.—In a patient nine months of age there was an evident incom- plete intestinal obstruction intermittent in character evidenced by marked constipation and periodic distention which was very pronounced. The peculiarity of this distention was that it could be relieved entirely by an enema combined with abdominal manipu- lation. The effects of such procedures could only be explained by some obstruction of a mechanical nature that was removed by this method of treatment. Abdominal section showed a thick fibrous cord, the remnants of the omphalomesenteric vessels extending from the umbilicus to the hepatic flexure of the colon and not to the ileum as would be expected. There evidently had been an infection of these vessels immediately after birth which had not been recognized. HERNIA AT THE UMBILICUS Protrusion of the abdominal wall at the umbilicus may be due to an improper development of the blastodermic layers, with non-union (ex- omphalos, hernia into the umbilical cord); or may result from a true fetal hernia after the umbilicus is lined with peritoneum, or a hernia occurring after birth through a weak umbilical scar. Hernia of the Umbilical Cord Morbid Anatomy.—This condition is a true fetal defect, due to a failure of union of the blastodermic layers, leaving as the anterior wall of the abdominal cavity a membrane covered with amnion externally and with peritoneum internally. Through this weakened parietal wall may occur a protrusion usually the size of a pear or an apple, but which may range from the size of a small finger-tip to that of a child’s head. The tumor is glistening and transparent, and shows through its walls the con- tents of the sac. These may include any or all of the abdominal con- tents, stomach, liver, Meckel’s diverticulum, omentum, intestines. Occa- sionally the child will be born eviscerated from the bursting of such a hernia in labor; and often its occurrence is associated with that of a spina bifida. The covering of this variety of hernia falls off with the drying up and dropping off of the umbilical cord. The contents are thus exposed. If the defect is small enough, it may granulate and epithelialize; but if this does not happen and operation is not resorted to, peritonitis and death will probably ensue. Treatment.—Operation offers a means of cure in these cases. Kindt reported 50 cures in a series of 65 operations. The management, therefore, should not be expectant. In view of the good results of operation, an attempt should be made as soon as possible after birth to close the opening in the abdominal wall either by cutting away the sac' in its entirety and suturing the abdominal walls together, or by separating the amnion from the peritoneum, replacing this and its contents into the abdominal cavity, and then suturing the walls. CONGENITAL UMBILICAL HERNIA Etiology.—This type of hernia occurs after the closure of the vis- ceral layers, and is due to pressure within the abdominal cavity and to the comparative weakness of the upper part of the umbilical ring, and to the extension of peritoneum surrounding the umbilical vessels, which, forming a sac, directs the force of the increased intra-abdom- 284 THE PRACTICE OF PEDIATRICS inal pressure. It may occur through the linea alba, just above the um- bilical ring, either alone or in conjunction with hernia at the umbilicus. Prognosis.—The tumor is usually from j to 1 inch in diameter, and may protrude as much as 1| inches. There is seldom any discomfort, although when the contents are extruded and reduced there may be some pain. Danger of strangulation is slight, and the prognosis as regards cure is good. The time required ranges from six months to two years. The younger the child, the quicker the cure. Treatment consists in retaining the hernia and allowing the opening to close, and is, therefore, entirely mechanical. Operation is rarely neces- sary. Of 2000 operations for hernia in children under fourteen years of age at the Hospital for Ruptured and Crippled, but 1.3 per cent, were for umbilical hernia. By far the most effective method of treatment is to bring together over the umbilicus (Fig. 57) two folds of skin, so that they meet in the median line and invert the umbilicus. These folds of skin thus form a splint which is retained by a strip of moleskin adhesive plaster 1 or 2 inches wide and sufficiently long to hold fast to the skin—usually Fig. 57.—Umbilical hernia reduced and adhesive plaster applied, about 4 to 6 inches. This method in our hands has proved the most satisfactory and has been followed by the most rapid cures. The objection to the use of a covered button or any form of pad, many of which have been recommended, is that unless it is very large the pad is apt to make strong pressure upon the abdominal opening, and while keeping the hernia reduced, prevent rapid closure of the ring itself. A pad or button may also interfere with the circulation and thus hinder the nutrition of the muscles and cause the weakness to persist. Umbilical trusses and bandages have been used repeatedly, and all have proved hopeless failures, and for one reason chiefly—the difficulty of keeping them in position. Any intelligent mother or nurse can be taught to apply the plaster as suggested above. The child may be bathed with the plaster in position. Ordinarily, it is best to apply a fresh piece every fifth day. Irritation of the subjacent skin sometimes occurs, and if this tendency exists, folds can be made at right angles to those previously made and the plaster applied again at right angles to the folds. By this means the excoriated skin remains uncovered. INGUINAL HERNIA 285 VENTRAL HERNIA AND DIAPHRAGMATIC HERNIA This form of hernia is of congenital origin, and is only occasionally seen in infants. It may be associated with umbilical hernia or may occur independently. It may be due to a failure of the recti to unite in the median line, or to weakness or imperfect development of the fibers of either muscle. Muscular atrophy following poliomyelitis was the cause noted in two cases. There is rarely any great protrusion of the abdominal contents, as in the other forms of hernia. Usually a ventral hernia manifests itself in a fulness or distinctly localized elevation of the skin over the site of the absent or weakened muscle tissue in the abdominal walls. The usual location is in the hypochondrium. Two or three hernias were observed in one subject in this locality. In one case the hernia was in the right lumbar region. Not all cases require treatment. Treatment.—The application of a 4-inch strip of zinc oxid adhesive plaster 2 or 3 inches wide, placed flat on the skin over the hernia is all that will usually be required. The support thus furnished must be con- tinued for several months. Operation may sometimes be necessary, but in our experience has not been required. Diaphragmatic Hernia.—These cases are very unusual. Only two have come under our observation. In both cases, as in others reported, the defect was located at the left anterior border of the diaphragm. This allowed the intestines to pass into the pulmonary cavity, displacing the heart and the lungs. As may be imagined, the physical signs thus produced are most unusual and puzzling. (See p. 383.) INGUINAL HERNIA Inguinal hernia is of rare occurrence in female infants, but is com- paratively frequent in males. It may be present at birth, or develop at a later period. The right side is more frequently involved. Double hernia, however, is not at all infrequent. Etiology.—Anatomic Conditions.—The special anatomic condition pre- disposing to inguinal hernia in infancy is the short and direct course of the inguinal canal. In the infant the internal abdominal ring is almost directly behind the external ring, and on practically the same level. In- complete closure of the inner opening, combined with weakness of the peritoneum in the neighborhood of the ring, thus affords easy egress to the hernia. At the femoral canal, on the contrary, the possible hernial opening is quite adequately protected, owing to the close relationship existing in the child between the anterior superior iliac spine, Poupart’s ligament, and the spine of the pubis. Consequently femoral hernia in childhood is rare. A more direct and exciting cause of hernia is the pressure exerted by the abdominal muscles in particularly from colic, and during paroxysms of whooping-cough. Diagnosis and Differential Diagnosis.—Inguinal hernia in infants is usually readily reducible, and this fact permits of making the diag- nosis positive. 286 THE PRACTICE OF PEDIATRICS Strangulated inguinal hernia may be confused with hydrocele of the cord, enlarged inguinal glands, and undescended testicle. In hydrocele the tumor is translucent, which may be readily proved by means of the following light test: A piece of dark, stiff paper is rolled in tube form, so that the orifice is | inch in diameter. One end of the paper tube is placed over the tumor, which is supported while a flash-light is placed underneath. The observer’s eye is now applied to the other end of the tube. If the light is not transmitted through the mass, hernia in all probability is present. Further, if strangulated hernia has persisted for even a few hours, there will be vomiting and pronounced abdominal distention. In the condition known as undescended testicle the testicle is absent from the scrotum and may be demonstrated in the canal as a small, ovoid, movable mass. The wearing of a truss over an undescended tes- ticle has been witnessed. When due to enlarged inguinal glands, the tumor is placed to the left or right of the canal. It is firm, hard, and fixed, and usually more than one gland is involved. It would seem that there should be no neces- sity for confusion in the differentiation of a gland mass. Prognosis.—The prognosis for cure of uncomplicated hernia without operative procedure is good. Many cases are cured in from six months to one year through the use of suitable appliances. Treatment.—The treatment of inguinal hernia in infants and young children is by mechanical appliances or by operation. In infants under one year of age operation is rarely required. A most satisfactory means for treating inguinal hernia has been the Hood frame truss, made of hard rubber. Measurement for the truss is taken around the hips on a plane with the hernia. The truss, if placed in hot water for a few seconds, or warmed slightly before a fire, can readily be bent, so as to fit the patient comfortably. When the truss is removed for the purpose of cleansing, which should be done twice a day, a helper should be at hand to maintain support at the ring, so that there shall be no descent of the hernia. One descent may mean that several weeks’ care has been brought to naught. The child should wear the truss day and night. The skin, where subject to pressure, should be kept well powdered when the truss is first applied, and the child is often made more comfortable by placing absorbent cotton beneath the hard-rubber pad. As the child grows the truss will have to be changed frequently. Its use should be continued for at least six months after the last descent of the hernia. Operation is required when the hernia becomes strangu- lated, and this procedure is always to be advised for older children if a cure is not effected after two years’ treatment by a truss. Many cases entirely recover in less than six months. The use of the truss in such instances, however, is to be continued with a view to protecting the parts and preventing a recurrence of the hernia under stress. DUODENAL ULCER Duodenal ulcer is a very unusual disease in infants. In all, only a few score cases have been reported. Holt found 99 cases reported in the APPENDICITIS 287 literature. To this he added 4 cases of his own which were observed at the Babies’ Hospital. Among 1800 autopsies, largely in children under one year, the postmortem records showed but 4 cases of duodenal ulcer. More recently Veeder1 reported 5 cases. Gerdine and Helmholz" re- ported 11 cases including necropsy findings, from which series of cases they deduced that the condition was of an epidemic infectious form in which diplococci and streptococci played an etiologic role. Age.—The great majority of the cases reported have occurred in in- fants under six months of age. The lesion has been found postmortem, in most of the cases not being recognized during life. In Veeder’s cases proved by autopsy the diagnosis of duodenal ulcer was made antemor- tem in one only. Two cases of duodenal ulcer in children have recently come under the writer’s observation. Illustrative Cases.—Case 1.—A boy three years old passed free blood in his stools in large amount and vomited blood repeatedly. Abdominal incision disclosed exten- sive peritonitis, with a mass of adhesions about the pylorus, nature’s attempt at closing the perforations. The patient died a few hours after operation. Case 2.—A boy two years of age became ill with abdominal pain and vomiting, fol- lowed by marked abdominal distention. On the fifth day he was seen in consultation and a diagnosis of a perforated appendix was made and concurred in by the operating surgeon who, however, found the appendix normal and a perforating duodenal ulcer. The abdomen contained about 1 pint of bile and blood-stained fluid. The child made a rapid recovery. Pathology.—The lesions as described by Veeder are as follows: The ulcers may be single or multiple, and vary from small areas of super- ficial necrosis to cleanly punched-out ulcers which involve all the layers of the intestinal wall, and which in a few cases have perforated, with a resulting peritonitis. They are found between the pylorus and the ampulla and are most commonly situated just beyond the pyloric ring. The ulcers are usually located on the posterior wall. Symptoms.—The only symptom of value is the presence of blood mixed with the stools. When this occurs in a marantic infant, ulcer should always be suspected. We would then have to differentiate duodenal ulcer from peptic ulcer, polypus of the lower intestine, fissure of the rec- tum, intussusception, ulcerative colitis, melena neonatorum, and diver- ticula. It will be observed that the diagnosis of duodenal ulcer is not a simple matter, and it is altogether probable that in the future diagnosis of the disease will continue to be made postmortem, particularly as in some of the cases no hemorrhage occured at any time. APPENDICITIS The Appendix.3—This organ, normally, is located in the right iliac fossa, subjacent to McBurney’s point, which marks the junction of the two lower thirds of a line connecting the right anterior superior iliac spine with the umbilicus. This position is attained as the result of intra-uterine changes in the intestinal canal, involving a gradual migration of the ileo- 1 Amer. Jour. Dis. Child., vol. vi, pp. 382-393. 2 Ibid., vol. x, No. 6, December, 1915. 3 Vide: Anatomy and Physiology of the Appendix, by Dr. Andrew McCosh, in American Practice of Surgery, Bryant and Buck vol. vii, p. 618 et seq. 288 THE PRACTICE OF PEDIATRICS colic junction from a primary position in the left iliac fossa upward to the right, beneath the liver, and finally downward into the right iliac fossa. When these changes are not completed, the organ will not be found in its normal adult location, but frequently higher up. Because of variations in development the appendix may or may not have its origin from the extreme lower portion of the cecum. The lumen of the appendix at its base is often very minute. Both of these facts partially explain the liability to inflammation. The total diameter of the organ is about \ inch, and the length, which is extremely variable, is usually between 2 and 3 inches. Various abnormalities in shape and direction occur, chiefly as a result of peritoneal adhesions. The appendix contains serous, muscular, submucous, and mucous layers. It is, however, essentially a lymphoid structure, well deserving the name “abdominal tonsil.” Like the tonsil, it attains its maximum development early in life, and, with the occurrence of the atrophic changes common in later years, shows a diminished susceptibility to infection. Appendicitis is not so rare a disease of early childhood as is usually taught. It occurs with sufficient frequency for the practitioner not to forget the possibilities of its unexpected development. Both acute and chronic cases are often overlooked because of the difficulty in diagnosis. In describing appendicitis, writers are inclined to divide the disease into types such as catarrhal, suppurative, gangrenous, and perforative. Such division for our purposes is hardly practicable. Because of the excess of lymphoid tissue in the child’s appendix, the patho- genic process may be extremely active, and a case that is catarrhal today may be gangrenous tomorrow. Not all catarrhal cases go on to the later stages. Nevertheless, it must always be remembered that appendicitis in the child is usually a much more active disease than in the adult. Bacteriology.—In order of frequency of attack according to Bower,1 the micro-organisms directly causing appendicitis are Bacillus coli, staphylococcus, streptococcus, B. pyocyaneus, and the tubercle bacillus. Age.—No age appears to be exempt. Our youngest patient was nine months of age. Shaw reported the case of a patient seven weeks of age. Symptoms.—That many errors are made in the diagnosis of appendi- citis in infants and young children is in no small measure explained by the fact that the cardinal symptoms, as laid down by writers, viz., vomiting, colic, and sensitiveness to pressure, do not complete the symptomatology. Pain is a relative term, and the complaint of pain, while it must be re- spected, is never to be relied upon. Some children will exaggerate the sensitiveness of the abdomen to pressure, and others will deny the existence of pain actually present. Vomiting and colic are very unreliable signs. Fortunately in children one sign is almost invariably present unless there is a malformed or misplaced appendix, which is most unusual. This sign of real value indicating an involved appendix in a child is localized muscle rigidity—a spastic right rectus. This symptom is entirely beyond the child’s control, and while young children may be difficult to approach, patience in gaining the child’s confidence, combined with attempts at diversion, will make a satisfactory examination possible. Deep pressure is not necessary. If both recti are persistently rigid, as 1 Appendicitis in Children, New York Medical Journal, cviii, No. 12, p. 502. APPENDICITIS 289 in a few cases, the fact in no way disproves the presence of a diseased appendix. Vomiting, pain, and colic are corroborative when there is a spostic right rectus. Alone they are suggestive of appendicular disease in children, but not diagnostic. With the rigidity and unusual sensitiveness to deep pressure, there is a tendency to flexion of the thigh on the abdomen, to relieve the tension of the abdominal muscles. Atypical cases may be seen, and in our experience have most often been due to an abnormally long appendix. Thus, in the case of a boy of twelve years, the appendix was 6 inches long and the abscess was located in the tip, which was in the right hypochondrium. In this case there was general muscle rigidity. Illustrative Cases.—In an eight-year-old child the diseased appendix was situated deeply in the pelvis. There was no pain or rigidity. Appendicitis was not diagnosed until rupture occurred and an acute localized peritonitis developed. In another child, with a very long appendix, the local symptoms were all referred to the left side. Operation was delayed, through no fault of the writer, until abscess and peritonitis, developed. The tip of the gangrenous appendix was located 2 inches to the left of the median line. Leukocytosis.—A leukocytosis is present in practically all cases, the differential count showing 70 per cent, or over of polymorphonuclear cells. Prognosis.—The prognosis depends upon the ability of the physician to diagnose the disease, his courage to act promptly, and the good sense of the family. In the young, appendicitis is usually of the fulminating type, and while temporizing may answer in the adult case it may be fatal to the child. Statistics of high mortality mean defective management. In the treatment of children over two years of age the results should be as favorable as in that of adults. If one uses ice-bags, stupes, and salines for three or four days and then operates, a high mortality is inevitable. Diagnosis.—The chief diagnostic symptom is rigidity of the abdomi- nal muscles, usually localized in the right side, sometimes general. Marked general abdominal rigidity was noted in a girl eleven years of age, whose appendix had not perforated. This symptom, with localized tenderness and the presence of a tumor, is to be looked upon as an independent diagnostic sign. All other symptoms to which much importance is at- tached are only of corroborative value. Differential Diagnosis.—In cases of intussusception and periodic vomiting there is no definite muscle rigidity, and in periodic vomiting no localized tenderness. Acute peritonitis may simulate a later stage of atypical appendicitis so closely that a differential diagnosis is impossible without an explora- tory incision. This should always be done in either event, whether peritonitis is of the more common origin or is due to intussusception. Acute pneumonia at the right base, with pleurisy, may produce signs closely simulating appendicitis, and is one of the conditions that may produce a spasm of the right rectus. In a very typical case operation for removal of the appendix might have been per- formed had not the patient presented the scar of a previous appendectomy wound. With pneumonia and pleurisy there are the unmistakable physical signs, the respiratory grunt, high temperature, and usually cough, to- 290 THE PRACTICE OF PEDIATRICS gether with the objective sign of rapid breathing—signs ordinarily suffi- cient to eliminate an error in diagnosis. In cases in which the physician feels that a differentiation is impossible the a>ray may be brought into use to clear up the situation. Treatment.—After a considerable experience with obscure acute and chronic abdominal conditions in children we have learned that an ex- ploratory incision should be made as soon as we realize we are not positive regarding the character of the trouble at hand. This has been learned through experiences which we regret. Proved acute appendicitis in chil- dren demands operation as early as possible. For the borderland case, with mild symptoms in which a positive diagnosis is not possible, rest in bed, a fluid diet without milk, and the ice-bag comprise the essentials in a scheme of treatment which may suffice. The recumbent position and quiet should be maintained until every sign of the trouble has disappeared. Interval Operation.—In the event of the child’s recovering from a well-defined attack without operation a suitable time should be selected for an interval operation. A second attack is very likely to follow in less than a year, with a strong probability of abscess formation. Further- more, we cannot time the subsequent attacks, and these may occur with great severity when the child is otherwise ill or away from home where necessary surgical skill may not be obtainable. CHRONIC APPENDICITIS Chronic appendicitis has a very decided entity. It occurs in older children. We have never seen a case before the fourth year. In pediatric consultation practice it is not unusual to find the condition after this period. Symptoms.—-The cases usually show one of two groups of symptoms. A child in apparent health has complained of frequent abdominal pain over a period of several months. If asked to place his hand over the painful area, he will almost always point to the umbilicus. There is no apparent sensitiveness over the appendix, no pain on deep pressure, and no rigidity of the recti. The pain is rarely severe and may occur at considerable intervals. In some cases the abdomen will never feel quite comfortable. There may be diarrhea alternating with constipation, or the stool may be perfectly normal and regular. In other instances unwarranted attacks of acute intestinal indigestion may occur, the occa- sion of which will not be explained by the habits of the patient. Another type of case shows periodic, acute manifestations. These include vomiting, fever, and colicky pains, with diarrhea. Two or more attacks during the year are usual. As in the cases of the first type there may be no localization of signs in the abdomen. Illustrative Case.—A badly diseased appendix, as large as an adult index-finger, was removed from such a patient who had complained of no localized symptoms other than a feeling of pressure or weight in the right side, but who always had, as he expressed it, an uncomfortable abdomen. Periodic or recurrent intestinal disturbances—so-called indigestion —that is not relieved by a rational life and careful feeding will usually ACUTE GENERAL PERITONITIS 291 be found due to either an elongated sigmoid (p. 256) or to chronic appen- dicitis. According to Comby many cases of cyclic vomiting have their origin in chronic appendicitis, and a considerable number of such cases have been cured by removal of the appendix. Illustrative Case.—Figure 58 is taken from a case of this sort. The patient, a boy eight years of age, had suffered for a long period from persistent stomach disturbance associated with hiccup, belching, and foul breath. He was on a very rigid diet of skimmed milk, simple vegetables, and flesh food. Raw fruit and sweets produced what were called “stomach upsets.” The x-ray revealed a large appendix that still contained the bismuth mixture six days after its injection. Operation disclosed a very long chronically inflamed appendix. Fig. 58.—Chronic appendicitis. (Retention in the appendix three days after injection, with segmentations which probably represent concretions.) Treatment.—Suspected subjects should be given an anesthetic after fasting for twelve hours, and then examined by deep palpation and through the rectum. If tumefaction is found in the right iliac fossa, operation for the removal of the appendix should be performed at the convenience of the patient. Acute general suppurative peritonitis is an infection of the peritoneum by pathogenic organisms. It is always a secondary disease, and its bac- terial cause is that of the primary lesion. Thus, peritonitis may follow um- bilical infection in the newborn, usually due to the streptococcus or to the Staphylococcus aureus, or may result from a general blood infection with the pneumococcus, the typhoid bacillus, the influenza bacillus, or strep- tococcus, whether the point of entrance be the upper respiratory tract or a surgical lesion. Peritonitis is a common complication of appendicitis, enterocolitis, or intestinal obstruction, and is then most often due to Bacillus coli communis, with or without the streptococcus. Peritonitis ACUTE GENERAL PERITONITIS 292 THE PRACTICE OF PEDIATRICS also may be due to the gonococcus, as the result of the progressive spread of vulvovaginitis, endometritis, and salpingitis in little girls. Finally, peritonitis may result from the extension of a pleural inflammation by means of the lymphatics, but the inflammation is then more often localized about the spleen or liver than generalized. The pneumococcus probably is the pathogenic agent in more than half the cases. An unusual illustrative case of acute peritonitis is recorded under the differential diagnosis of intussusception, p. 279. Pathology.—The exact character of the inflammation depends upon the infecting organism. The process, however, uniformly involves con- gestion, exudation of serum and lymph, and the formation of adhesions. Depending on the source and degree of infection, peritonitis may be localized, “spreading” or general, and serous, seropurulent, purulent, or fibrinous. The most frequent infecting agents are the colon and the typhoid bacillus and the streptococcus, staphylococcus, pneumococcus, and gonococcus. In cases of streptococcus peritonitis the fluid is thin and widely diffused, and in pneumococcus infections, thick, greenish-yellow, purulent, and associated with fibrinous deposits and many adhesions. Gonococcal peritonitis is seldom diffuse. Pus with a characteristic fecal odor is suggestive of appendical or intestinal perforation. When the peritonitis is of limited extent, the most common sites for the localization of the inflammation are the iliac fossa, pelvis, and subdiaphragmatic regions. Abscesses occasionally perforate spontaneously at the umbilicus. When recovery ensues, the peritoneum frequently becomes the seat of permanent adhesions which may or may not occasion symptoms. Symptoms.—There are but three diagnostic symptoms of value: persistent vomiting, marked tympanites, and obstinate (and often abso- lute) constipation. These manifestations comprise a symptom-complex that is practically always present in acute peritonitis. Vomiting may be absent in very acute and fatal cases. The temperature is usually persistently high—103° to 105° F. The pulse is small, soft, and quick, and the child appears and is very ill. The respiration is short and rapid; there is incomplete expansion. There are no evidences of pain except upon manipulation. The onset of all symp- toms is usually, but not invariably, abrupt. It may be two or three days before the symptom-complex as described is present. Illustrative Case.—A fine healthy boy four years of age seen in consultation with Dr. Harriet Hyde developed a severe staphylococcus infection of the tonsils. On the fourth day of the illness symptoms of acute peritonitis developed with paralytic ileus and death in a few hours. Duration and Prognosis.—Death rarely occurs before the third day, and the cases that pass ten days are rare. We have never known a case to recover. Our cases have all been those of children under two years of age, with a few exceptions. Illustrative Cases.—A child of three developed a streptococcus infection in conjunc- tion with endocarditis. Another patient, a strong, vigorous girl, three years of age, developed a moderately severe enterocolitis. Response to treatment was fairly prompt, and in ten days the THE INTESTINAL PARASITES 293 child was convalescent. Suddenly she developed marked distention of the abdomen, persistent vomiting, and obstinate constipation. These symptoms, with gradually in- creasing prostration, continued for three days, when the child died. The autopsy showed an acute general streptococcic peritonitis. Streptococcus was found in the enlarged mesenteric glands, indicating that the intestinal tract was the source of the infection. Othe*- cases have been those of appendicitis seen too late to forestall the occurrence of perforation. The prognosis in older children after the fifth year is said to be more favorable. Differential Diagnosis.—The only condition which acute peritonitis may simulate in infants and runabouts is intestinal obstruction, par- ticularly that due to intussusception. Intussusception in a large majority of the cases occurs in infants under a year of age. Further, in intussuscep- tion there is no associated illness, and fever, if present, is insignificant; while the stools almost always contain blood-stained mucus or clear white mucus. Treatment.—Every case of acute peritonitis in a young subject should have the benefit of an exploratory incision. There is always a possibility in obscure cases (and many cases are obscure) that the trouble is of ap- pendicular origin or that there may be some other localized process which drainage might relieve. Acute general peritonitis is a very fatal disease, and the outlook cannot be made worse by incision and drainage. THE INTESTINAL PARASITES The most common of the intestinal parasites found in children are Ascaris lumbricoides, or round-worm, Oxyuris vermicularis, or thread- worm, Tenia, or tapeworm, and Uncinaria, or hook-worm. The Blood in Infections by Intestinal Parasites.—Patients with teniasis or uncinariasis frequently present a pronounced degree of ane- mia of the chlorotic type. In occasional cases of tape-worm infection the blood-picture resembles that of actual pernicious anemia. Where un- cinariasis is prevalent and the inhabitants are subject to constant infec- tion from the soil, such terms as “Egyptian chlorosis,” “miner’s anemia,” and “brickmaker’s anemia” are current synonyms for the disease. Leukocytosis in the parasitic infections is not characteristic, but may occur during the acute stage of trichiniasis. Eosinophilia, however, is a very characteristic manifestation of reaction to the parasitic toxins, and in trichiniasis often attains a degree of 20 to 50 per cent. Stiles re- ported that in uncinariasis the chronic cases with poor resistance show little eosinophilia, while those undergoing improvement under treatment afford counts averaging as high as 13.2 per cent.1 Ascaris Lumbricoides (Round-worm).—This parasite is a very fre- quent inhabitant of the small intestine. The worm is 5 to 10 inches long, cylindric in form, and closely resembles an ordinary earth-worm. Large numbers may exist in the same patient, and have been known to cause serious secondary symptoms, such as obstruction of the bile-duct or a severe attack of choking, induced by the migration of the worms from the esophagus into the larynx. They have been known to invade the eustachian tube. The ova are taken into the digestive tract in uncooked 1 Osier’s Modern Medicine, vol. i. 294 THE PRACTICE OF PEDIATRICS food and occasionally in drinking-water. The eggs are of oval form, and when present in the feces may be distinguished by their thick shells and “mammillated” borders and by the absence of segmentation. Symptoms.—The round-worms, if in considerable number, may pro- duce colic or constipation, the latter oftentimes alternating with diarrhea. Nervous disturbances of an urgent character are not uncommon. In the great majority of our cases, however, no single symptom has been prominent, and the fact that the child had parasites in the intestine has been first learned when a worm has been passed by the rectum. Illustrative Case.—A patient, three years of age, had repeated convulsions. The mother stated that the child had passed a couple of round-worms the day before. Fol- lowing the giving of 1 ounce of castor oil, and after an hour, 2 grains of santonin, 43 large round-worms were passed during the next twenty-four hours. This is the largest number we have known to come from one child. The round-worm is relatively rare in New York City children. In children who live in the country it is of fairly common occurrence. Treatment.—At bedtime it is well to order from 2 to 4 teaspoonfuls of castor oil. Early the following morning, about two hours before breakfast, santonin is to be given. For children under two years of age a suitable dose is 1 grain; for those from two to four years of age, 1| grains; and after the fourth year, 2 grains. The santonin is prescribed in a powder or capsule, with an equal quantity of sugar-of-milk. If the passage of worms follows its use, the treatment should be repeated in three days; and again in a week, if worms are passed after the second treatment. Oxyuris Vermicularis (Thread-worm or Pin-worm).—Thread-worms are of more frequent occurrence in city children than are either round- worms or tapeworms. The thread-worms have their habitat in the lower portion of the colon, where they become attached to the mucosa, and occasionally produce considerable catarrhal inflammation. Exceptionally they may invade the appendix and excite inflammation requiring surgery. The oxyuris is an insignificant looking object, light in color, from \ to \ inch in length, and of the diameter of a pin. The ova are not so large as those of the ascaris. Raw fruit and uncooked vegetables may convey the infection. Symptoms.—The worms produce an irritation and itching about, and a pricking sensation within, the anus. The discomfort is bitterly com- plained of after the child is in bed at night, the parasites being particularly active at this time. If there is any doubt as to their presence, the patient should receive a full dose of castor-oil—at least 2 teaspoonfuls. The discharges should be kept for inspection. If the parasites are present, they will usually be found embedded in a considerable quantity of mucus, in the form of pieces resembling white thread from \ to f inch in length. Treatment.—Santonin, recommended by some writers as of service in these cases, has been without the slightest value in our hands. In fact, the use of drugs of any kind by mouth seems to be of very little value. After the third year turpentine in 1-drop doses after meals is probably the most valuable form of internal medication. It may be given in emul- sion or dropped upon sugar. Rectal Injections.—Local treatment with the infusions of garlic or quassia is our principal reliance in the management of the obstinate cases. THE INTESTINAL PARASITES 295 When the worms have existed in the bowel for a considerable time the resulting irritation causes a profuse secretion of mucus in the descending- colon and sigmoid. This mucus must be washed out before any direct treatment can be effective. The colon should first be irrigated with a solution of 1 tablespoonful of borax to a pint of water. For this purpose a No. 18 American catheter introduced, if possible, 10 inches, should be used, as in colon flushings. The child should be encouraged to bear down and expel the water alongside the tube, no attempt being made to have the solution retained. After the preliminary washing is complete, 8 ounces of the infusion of quassia may be passed into the colon. To facilitate re- tention of the fluid the tube must be quickly withdrawn. The child may then be placed on the left side, with the buttocks elevated on a pillow. This position, or at least the recumbent position, should be maintained for one half-hour after the injection is given. A solution of bichlorid of mercury 1 : 10,000 may be used in the same way. For ordinary family use, however, the garlic or the quassia is much safer and equally effective. Garlic used in infusion identical with quassia is particularly effective, but its very disagreeable odor makes its use objectionable in many house- holds, and therefore we advise it only when other means fail. After the worms and all evidences of their presence disappear, the treatment should be continued for some time on alternate days, and then twice a week, gradually reducing the frequency of the irrigations until they are no longer required. Few cases recover in less than four weeks, and in many instances it will be found necessary to continue the treatment for months. We have never seen a case, however, which did not eventually respond to per- sistent treatment. Tenia (Tapeworm).—The tapeworm is a long, flattened organism, consisting of a head or scolex and hundreds of individual proglottides or offshoots derived from the head. Each segment in the series contains a large number of eggs. After the discharge of the segments from the body these ova are ingested and undergo a period of development in the tissues of an intermediate host, eventually forming the cysticerci or encapsulated bladder-worms which give the “measle” appearance to infected meat. This meat, when insufficiently cooked, conveys the cysticercus to the stomach of the patient, where the digestive juices liberate from the cyst wall a head which is capable of becoming attached to the mucosa of the child’s alimentary tract and producing a mature parasite. The chief varieties of tapeworm are Taenia saginata, or beef-worm, Taenia solium, or pork-worm, Bothriocephalus latus, an inhabitant of fish, and Taenia elliptica, which passes an intermediate stage in the vermin of household pets. Taenia saginata attains a length of from 12 to 20 feet. The head is from 1 to 2 mm. in diameter, and contains four suckers, but no hooklets. Taenia solium is rarely over 12 feet long. The offshoots from the median canal forming the uterus of a segment show less branching than in the case of Taenia saginata, and the developed segments in Taenia solium are more nearly square. The head has a short rostellum with a circle of hooklets. Bothriocephalus latus is far more common in northern Europe than 296 THE PRACTICE OF PEDIATRICS in America. When mature, this worm is over 25 feet long. The seg- ments are unusually broad, and the head is oval in outline and contains two lateral grooves. Taenia elliptica occurs occasionally in very young infants. It is only 6 to 12 inches in length, and its segments are long and narrow. Symptoms.—The tapeworm may produce symptoms of disturbed in- testinal digestion, such as colicky pain and diarrhea. Usually, however, the first warning that the child is affected is afforded by the passage of segments of the worm. Illustrative Cases.—A worm 14 feet in length was expelled, after treatment, by a little girl four years old. There had never been a symptom of its presence other than the passage of several of the segments. A child eighteen months of age passed 18 feet of a tapeworm without dislodging the head. Treatment.—At bedtime to 1 ounce of castor oil is to be given, and early next morning, two hours before breakfast, | dram of the oleo- resin of male-fern (aspidium), in emulsion or in capsule. During the day a light fluid diet only should be allowed, such as broth, gruel, and fruit juices. One treatment with a good preparation of the male-fern will usually bring away the worm entire. The head should be carefully searched for with the magnifying-glass. If the head is not found, the treatment should be repeated after an interval of twenty-four hours. Uncinaria (Hook-worm).—The two forms of this parasite, Ankylos- toma duodenale and Uncinaria americana, exhibit certain morphologic differences, the most marked of which is the existence, in ankylostoma, of two pairs of ventral, hook-like teeth, which are not present in the American species. The hook-worm measures from | to f inch in length. The ova, in large numbers, are present in the feces, and may be recognized as small oval bodies, usually clear in appearance, about 50 x 30g in size, showing various stages of segmentation. After the administration of thymol, followed by a saline cathartic, the worms themselves may appear in the stools as small objects, a little thicker than a pin, about \ inch long, and with the characteristic, retroverted hooked end. The hook-worm has been known for many generations, but only during the past twenty years has uncinariasis received due attention. In certain localities—notably the West Indies and the Southern States—the soil is very generally infected, and a considerable proportion of the population harbor the parasites. These not only remove blood from the circulation of the victim, but elaborate a toxin which is thought to assist in the causation of the significant anemia of this disease. Infection usually takes place from the soil, through the skin of bare feet. Infection may also take place through the skin of the hands, or by means of the gastro-intestinal tract, through the eating of raw fruit or vegetables. Symptoms.—The symptoms are those of digestive disturbance com- bined with progressive anemia. The anemia is often of an extreme degree. Abdominal discomfort of considerable degree may exist and this possibly gives rise to the curious habit of earth-eating, which these patients may acquire in their desire for the relief which the ingestion of food usually affords. Stiles reported a case in which a boy ate three coats, thread by THE INTESTINAL PARASITES 297 thread, in twelve months. As the disease progresses, the face and ankles may become edematous. The stools contain occult blood. Lassitude and incapacity for sustained effort are prominent symptoms, and unless the cause of the disease is eliminated, the child falls behind in both physical and mental development. Treatment.—Thymol is specific for the hook-worm. A purgative should precede the administration of the drug. Twelve hours before administering the thymol a full dose of cascara sagrada or Epsom salts should be given. The thymol should be given in solid form, 5 to 10 grains every three hours, until four doses have been given. The drug is best given in capsules or pills. Twelve hours after the last dose a saline cathartic should be administered. Ten days after the administration of the thymol the stools should again be examined for the ova of the parasite, and if ova are found, the treatment should be repeated. Thymol poisoning is indi- cated by dizziness and discoloration of the urine. When these symptoms appear, the treatment should be discontinued and further purgation brought into use. During the active treatment the diet should consist of milk, broths, and gruels. The anemia and malnutrition should be managed along the lines suggested under the respective headings. Trichiniasis is a disease which children may occasionally acquire from the eating of uncooked ham, sausage, or pork. In localities where meat inspection is rigid cases of this infection are relatively rare. Trichina spiralis (Trichenella spiralis) is not infrequently found in hogs. The fe- male parasite deposits larvae in the submucosa, whence they are carried by the lymphatics to the blood-stream, and on reaching the voluntary muscles become encapsulated. When the uncooked, infected meat is eaten the capsules undergo dissolution, and the contained trichinae are liberated in the digestive tract of the patient. The forms attain full development in the small intestine, and about a week after the ingestion of the meat set free a new brood of embryos. Van Cott and Lind1 found the Trichina spiralis in the cerebrospinal fluid. These findings have since been confirmed by Young, Cummins, and others. In doubtful cases an examination of the cerebrospinal fluid serves as a means for the possible confirmation of a diagnosis. Symptoms.—'The severe symptoms of trichiniasis develop about ten days after the eating of the infected meat, frequently following a period of preliminary gastro-intestinal disturbance. When well advanced, the disease may be mistaken for typhoid, malaria, influenza, nephritis, or acute rheumatism. Fever of a remittent type, great muscular pain and soreness, and edema of the face and eyelids suggestive of nephritis are the more pronounced effects. The blood shows not only leukocytosis, but a marked grade of eosinophilia. The symptoms usually subside after a week or ten days. Romanowitch demonstrated that in traversing the intestinal mucosa the trichina deposits bacteria which may distribute secondary infections. Flow important this fact may be in the explanation of symptoms occurring in this disease remains to be determined. In doubtful cases trichiniasis may be diagnosed by the microscopic demon- stration of the encapsulated parasites in a bit of muscle tissue removed 1 Jour. Amer. Med. Assoc., vol. lxvi, No. xxiv. 298 THE PRACTICE OF PEDIATRICS under local anesthesia from the deltoid, biceps, or gastrocnemius of the patient. Illustrative Case.—A girl eight years of age developed muscle soreness, edema of the skin, and especially marked swelling and stiffness of the muscles of the left leg. Trichiniasis was suspected, and a small portion of the deltoid was removed, which showed the encapsulated parasite. Treatment.—At the outset of the disease thorough catharsis is of unquestionable value, for it has been estimated that “each female parasite removed from the intestine means a reduction of the muscular infection by from 1500 to several thousand worms.”1 Calomel is undoubtedly indicated for this purpose, and this drug should be given in doses aggre- gating 1 to 2 grains, accompanied by 10 to 20 grains of bicarbonate of soda, and followed after six hours by a saline cathartic. Thymol may be given in the manner suggested under treatment of uncinariasis, but the position of the parasites deep in the intestinal mucosa renders most of them secure from the action of an anthelmintic. After the disease has become established the treatment is solely symptomatic, consisting in the use of means to relieve pain, control temperature, and support the pulse, which in severe infections may become weak. 1 C. W. Stiles, Osier’s Modern Medicine, vol. i. IX. THE RECTUM AND ANUS THE RECTUM IN CHILDREN In the child the division between the pelvis and abdominal cavities is less marked than in the adult, and the rectum is less distinctly a pelvic organ. The infantile pelvis, moreover, is peculiarly narrow, so that the course of the terminal portion of the intestine is nearly perpendicular. This peculiarity, combined with the greater mobility of the child’s rectum, renders digital examination per rectum of great value in palpating diseased organs within the abdomen. The same anatomic conditions, associated with weakness of the levatores ani, are influential in the causation of prolapsus recti in children. IMPERFORATE ANUS—ATRESIA ANI The greater portion of the alimentary tract is derived embryologically from entoderm, but the caudal part is formed from the elevation of a fold of ectoderm which surrounds a crater-like hollow called the proctodeum. This latter ectodermal invagination is separated from the entodermal gut till about the fourth week of fetal life by the anal membrane, a portion of the eloacal membrane. Cases of imperforate anus or atresia ani may be due to a complete or partial persistence of this membrane so that the proctodeum or external invagination does not communicate with the caudal portion of the hind-gut or is connected with it only through an abnormally small opening. Other causes of imperforate anus may be: (1) Deficient development of the hind-gut so that there is an interval between the gut and the proctodeum. (2) The rectum may open into the vagina, uterus, bladder, or ureters. (3) Persistent cloaca. PERSISTENT ANAL MEMBRANE Slight or moderate constriction of the anal ring due to partial per- sistence of the anal membrane is a fairly common cause of constipation, colic, and difficulty in defecation in small infants. On careful digital examination a tight membranous ring may be felt at the level of the external sphincter. Frequently the gut above is empty and ballooned up with gas which is violently expelled upon withdrawal of the examining finger. The ring should be gently dilated. One such dilatation may suffice; more often it has to be repeated once or twice till the distention, colic, constipation, and difficulty at stool is relieved. Complete persistence of the anal membrane necessitates its being broken down to permit the free passage of feces. The other forms of imperforate anus require more extensive and more difficult surgery. The rectum of every newborn infant who suffers from the symptoms described should be digitally examined with the purpose of determining the presence of this small membrane. This may at times account for very urgent symptoms. 299 300 THE PRACTICE OF PEDIATRICS PROLAPSE OF THE ANUS AND RECTUM In anal prolapse there is an eversion of the mucous membrane, a condition often presented in constipation and sometimes seen in diarrheal conditions of the dysenteric type, in which there is a tendency to con- siderable tenesmus and straining. If the case is neglected, the prolapse occurring repeatedly for many days in succession in cases of constipation, or several times a day in the acute diarrheal cases, the sphincter gradually becomes weakened, the prolapse more pronounced, and soon a consider- able portion of the involuted rectum appears with each defecation. Chil- dren thus affected usually show evidence of illness apart from the local condition and the constipation. They are usually underfed and poorly nourished. Many are rachitic, or show the evidences of a previous rachitic state. Treatment.—Cases of simple eversion are usually relieved by con- trolling the diarrhea; or, when due to constipation, by supporting the perineum during defecation. This support is best furnished by wrap- ping a considerable quantity of absorbent cotton around the index- finger, which rests against and supports the perineum. The child should lie on the back during defecation. The troublesome cases are those due to constipation in “runabout” children, in whom the prolapse has been re- peated every day for several months. In such cases a wide adhesive strip placed across the buttocks, high enough to permit of bowel evacuation, will prevent the prolapse. INFLAMMATION OF THE ANUS An acute painful inflammation of the anus and of the skin surround- ing it is frequently seen in children after a diarrhea of some days’ dura- tion. It is also seen in weakly, delicate children without any marked intestinal disturbance. The inflammation produces considerable dis- tress during the passage of a stool, and is conducive to constipation, because the child soon dreads to have a bowel movement and tries to avoid it. Treatment.—The child’s nutrition and management in general must be first carefully looked after, as elsewhere suggested (p. 140). For the local trouble the free use of warm water after each defecation is neces- sary. This is to be followed by a generous application of an ointment made as follows: Ib Ichthyolis 5j Unguenti aqua; rosae §j.—M. Instructions are given that the parts are to be kept covered with the ointment, applied on a piece of old linen, which should be changed every three hours. This treatment is usually followed by prompt relief. FISSURE OF THE ANUS Anal fissure is a condition that usually occurs in quite young chil- Comparatively few cases have been personally seen in children over two years of age. Rough manipulation may be a cause, as in the case of unskilled use of the syringe or rectal tube. With very few exceptions, however, the fissure is due to the stretching of the parts by the passage PROCTITIS 301 of large fecal masses, which cause minute lacerations of the mucous mem- brane within the anal ring. Under a good light gentle separation of the buttocks will usually bring the laceration into view. Symptoms .—There are few more painful affections. The vigorous crying preceding and during the defecations aids the mother in locating the source of the child’s trouble. Occasionally the fecal mass will be streaked with blood. The constipation which causes the trouble is aggra- vated by the painful nature of the condition, as the child soon learns to dread an evacuation, and postpones the act until medication or some manipulation is employed to induce a movement. Illustrative Case.—A little girl, twenty months old, was brought for treatment because she cried and objected to being placed in position for a bowel evacuation, and cried even more during the evacuation. On the day preceding the office visit the mother feared the child would have a convulsion so great was her distress. Examina- tion of the rectum showed two rather small fissures extending through the anal mucous membrane. Treatment.—Diet.—For a prompt repair of the fissures it is necessary to render the stools soft. This, in the bottle fed, is often easily accom- plished by the addition to each feeding of 1 or 2 teaspoonfuls of one of the malted foods, such as Mellin’s food or malted milk. In other instances one feeding of malted milk each day may be substituted for one of the regular feedings, in the strength of 4 to 6 teaspoonfuls in 8 ounces of water. Drugs.—If drugs are necessary or are preferred, the addition of 2 teaspoonfuls daily of the milk of magnesia to the milk food will prove of value. A teaspoonful of sweet oil after two or more feedings will like- wise usually have the desired softening effect upon the stool. Local Measures.—Proper regulation of the bowel function, while absolutely necessary for a cure of the laceration, is not of itself sufficient to effect permanent relief. The parts must be thoroughly washed with warm water and Castile soap after each defecation. After the washings, and at three-hour intervals during the day, 25 per cent, of ichthyol- ammonium-sulphate in zinc ointment should be applied with a clean index-finger, which is introduced well up into the anal aperture. If the fissure is deep, the treatment should be begun by applying to the parts a solution of novocain. The fissure may then be cauterized with 50 per cent, solution of nitrate of silver, applied on a cotton-tipped probe. Twelve hours later the ichthyol ointment may be used as in the milder cases. PROCTITIS Inflammations of the rectum are of three different forms—catarrhal, croupous or membranous, and ulcerative. Catarrhal 'proctitis is usually associated with colitis higher in the bowel. When confined to the rectum, the process may be due to the careless use of irrigations or irritating suppositories, or the activity of thread-worms. The mucous membrane is red and swollen, and exudes not only mu- cus, but a small amount of blood. In gonorrheal proctitis, which occa- sionally complicates a vulvovaginal infection by the same organism, the discharge from the inflamed parts is characteristically purulent. Membranous proctitis may result from diphtheria of the genitals or 302 THE PRACTICE OF PEDIATRICS from a local streptococcus infection. The morbid lesions closely resemble those of membranous colitis, and are not essentially different from those which occur in membranous inflammations of the throat. The grayish, organized exudate may be visible on the mucosa of the prolapsed bowel, or appear in fragments in the stools. Ulcerative 'proctitis is usually secondary to a severe catarrhal proc- titis, in which case the lesions tend to remain superficial. Follicular ulcers of greater depth may occur in connection with follicular colitis. Syphilitic and tuberculous ulcerations of the rectum are rare. Holt reported one case of the tuberculous type, and recorded Steffen’s observa- tions of three others. Symptoms.—In all forms of proctitis the movements of the bowels are frequent, and associated with tenesmus and the discharge of mucus and small amounts of blood. Prolapsus recti is not uncommon, and after reduction shows a strong tendency to recur so long as the severe peristaltic activity of the bowel persists. The character of the discharge is of value in differentiating the existing type of inflammation. Treatment.—In mild cases of the catarrhal form injections of warm starch solution, alkaline liquid antiseptics, or sweet oil will effect a cure, provided the primary cause of the irritation has been removed. When the process is diphtheric, antitoxin should be promptly administered, as in cases of laryngeal diphtheria. Ulcerative proctitis requires especial care involving the use of cleansing irrigations and suppositories of tannigen, belladonna, opium, or cocain, combined with local application, at intervals, of a solution of silver nitrate of from 2 to 5 per cent, strength. For the gonorrheal cases Koplik has advised rectal injections of 2 per cent, protargol solution, at a temperature of 105° to 108° F., twice daily. An abscess of this nature is the result of preceding adenitis of the lymph-glands in the neighborhood of the rectum. Symptoms.—The first sign will be that of pain on defecation or upon manipulation. Upon examination an oval, indurated mass will be found under the skin, usually not deeply placed. Much pain is evidenced during the examination. In most instances there is redness of the skin over the involved gland. Rarely can fluctuation be made out by palpa- tion. Suppuration, however, follows the primary infection very rapidly, and a distinct area of reddened and inflamed skin indicates the presence of pus beneath. Children’s hospitals, children’s asylums, and dispensary services supply the majority of these patients. Occasionally a case is seen in private work. Treatment.—All that is required is a free incision, daily washing out of the abscess cavity with a 3 per cent, solution of hydrogen peroxid, and packing with sterilized gauze moistened with a saturated solution of boric acid. A layer of gauze, covered with oiled silk, should cover the dressing, to protect the wound from further infection by the fecal discharges. In case the granulations are sluggish, as they may be in marasmic infants, the gauze used for the packing may be saturated with balsam of Peru. ISCHIORECTAL ABSCESS X. DISEASES OF THE LIVER ABNORMALITIES OF FUNCTION AND SIZE The liver in infants and children is very rarely the seat of primary disease, and in the mortality of childhood as an immediate cause plays a very unimportant role. Derangement of function of the organ, on the other hand, is unques- tionably at the bottom of many disorders not at all understood at the present time. In conditions of toxemia, particularly in so-called acidosis, the failure of normal oxidative processes on the part of the liver constitutes a most serious phase in the altered metabolism of the body. The organ may be enlarged temporarily or permanently from various causes. One of the most common is congestion induced by cardiac insufficiency. Active hyperemia may be induced by indigestion. In rickets and syphilis and in various diseases of the spleen and lymph-glands the liver is persistently enlarged. Fatty change in the liver in early life is often found at autopsy. It is found in greater or less degree in practically all infants and young children who die from prolonged and exhausting diseases. Presumably the infiltration is of a temporary nature, and, so far as is known, has no symptomatology of its own. In many cases that recover the liver must have undergone not only fatty infiltration, but a considerable degree of fatty degeneration. It is rare not to find more or less fatty change at a postmortem examination of a child under one year of age. In some cases the involvement is so extensive that the entire organ is firm, smooth, and of a yellowish color. In other cases there are only localized evidences of the fatty process. Usually the organ is not enlarged. The condition is not to be diagnosed during life. If there is a derangement of function, this is not of such a nature as to make the actual hepatic conditions manifest. Acute Yellow Atrophy.—Fatal cases of this disease in children are reported at rare intervals. ABSCESS OF THE LIVER In the newborn abscess is the result of an infection usually acquired from the umbilical veins. Several cases in older children have been reported, in which the abscess was caused by the migration of round-worms into the hepatic duct. Abscess of the liver may result from any pyemic condition. Its rare occurrence demonstrates the hepatic powers of resistance against microbic invasion. Amoeba coli has been the cause of abscess in a considerable number of cases. Symptoms.—Enlargement of the organ, associated with the presence of marked tenderness, is usual. Pain is a very constant symptom, and may be referred to different points in the abdomen, not infrequently 303 304 THE PRACTICE OF PEDIATRICS being felt at the umbilicus, or localized between the right scapula and spine. Among the most prominent active manifestations are repeated chills, a widely ranging septic temperature, and vomiting. Occasionally there is diarrhea. Exploration should be performed, and if pus is located, aspiration and drainage should follow. Abscesses not operated upon are apt to perforate into the peritoneal or pleural cavity. Cases of perforation into the intestine have been followed by recovery. Cirrhosis of the liver belongs to the curiosities of pediatric practice- All the cases reported represent, roughly speaking, the observations of as many men. In the reported cases in which there has been a supposed etiologic factor, syphilis, alcohol, and the infectious diseases have been looked upon as the agencies causing the disease. Toxic substances of widely different character are apparently capa- ble of causing cirrhosis of the liver in the young. The possibility of cirrhotic changes occurring as the result of prolonged absorption of toxins from fermentative processes in the intestine must be considered as in certain instances of adult cirrhosis. Symptoms.—At first there is enlargement of the liver and the spleen. Persistent but not severe icterus and ascites supervene. The patient shows early evidences of malnutrition, and a cachexia that is strongly suggestive of the underlying condition. As the case progresses the liver becomes very much reduced in size, diarrhea becomes fairly constant, vomiting frequent, and dilatation of the superficial abdominal veins occurs. Bronchopneumonia is the usual terminal complication. Treatment.—The management is entirely symptomatic. Abdominal paracentesis may temporarily relieve the embarrassed respiration and the general discomfort occasioned by the large amount of fluid in the abdom- inal cavity. CIRRHOSIS OF THE LIVER BILIARY COLIC Older children have paroxysmal pain and exhibit persistent jaundice. Illustrative Case.—A girl eight years old, the child of a physician, had suffered from Kermanent jaundice of three years’ duration, with intermittent attacks of colic followed y an increase in the intensity of the jaundice. Operation revealed a large calculus in the common duct. ICTERUS (OBSTRUCTIVE JAUNDICE; CATARRHAL JAUNDICE) Jaundice of this type in children is usually associated with duodeni- tis, and is caused by a swelling of the lymphoid bodies in the mucous membrane of the common bile-duct at its terminal opening into the intestine. The jaundice is due probably to the same form of infection that caused the duodenitis. Cases often occur in groups of two or three in the same family. Illustrative Cases.—In November, 3 children and 2 adults—the mother and nurse— had pronounced jaundice with the usual manifestations. Six weeks before all these people had suffered from malaria. We have seen but one case in which jaundice was due to cholelithiasis. This ICTERUS (OBSTRUCTIVE JAUNDICE; CATARRHAL JAUNDICE) 305 patient, a girl six years of age, had distinct attacks of biliary colic, accompanied by passage of gall-stones and followed by intense jaundice. She was eventually operated upon and many stones were removed from the gall-bladder. Symptoms.—The onset is almost never marked by high temperature or evidence of severe gastric disturbance. Usually the first signs are loss of appetite, coated tongue, rise of a degree or two in temperature, and listlessness. The yellow discoloration of the conjunctiva and skin soon appears, and this, with the high-colored urine and slightly colored or grayish stools, makes the case complete. The liver is usually enlarged an inch or two below the ribs, and often is slightly tender. The spleen is also slightly enlarged. We have never known a fatal case, although such have been reported. Vomiting.—In a most severe case the vomiting continued for five days, neither food nor water being retained. Vomiting is present in most cases. The child vomits two to three times, or at intervals for a day or two. Treatment.—Diet.—The reason why gastric disorder is considered so prominent a symptom by many writers is possibly because of the gastric disturbance produced by the treatment. We are advised to place the patient on a milk diet and give calomel. We know of no treat- ment better calculated to produce vomiting and increase both the intes- tinal infection and the jaundice. The treatment which has been found most satisfactory is simply the use of very little food for twenty-four hours. Water is given as a drink, and later, well-salted chicken or mutton broth may be given with toast if the child asks for food. He should not be urged to eat. The following day broths, gruels, and orange juice, with stewed fruits or lemonade, may be given if wanted. Drugs.—The only medication used consists of rhubarb and soda. To a child five years of age 4 grains of pulverized rhubarb and 8 grains of bicarbonate of soda may be given from two to three times daily, together with considerable water. For a day or two sufficient medicine should be given to produce a free laxative effect, but not necessarily enough to purge the patient. Usually on the third day it is advisable to begin with tincture of nux vomica and dilute hydrochloric acid—from 2 to 4 drops of each, well diluted. When the stools are again normal, the usual diet may be resumed, milk not being used for a week afterward. Rhubarb and soda are best given as follows: 1$. Pulveris rhei gr. xlviij Sodii bicarbonatis gr. xcvj Syrupi rhei aromatici §j Aquae q. s. ad. gij M. Sig.—Shake well. One teaspoonful two or three times daily after meals. Other measures to hasten the disappearance of the jaundice are daily irrigations of the bowel and the administration by mouth of phosphate of soda in water before meals, the dose being determined by the effect obtained. To most children the effervescent preparation is the more palatable. For a fortnight after the acute symptoms have abated a diet should be maintained that is relatively fat free. Eggs and top milk particularly should be excluded. XI. DISEASES OF THE RESPIRATORY TRACT The Nose and Throat ACUTE RHINITIS (CORYZA; SNUFFLES; COLD IN THE HEAD) Acute rhinitis is a very common ailment throughout childhood. Newborn babies, ‘‘runabouts,” and school children alike are sufferers. The so-called cold in the head is unquestionably an infection and may be transmitted from the diseased to the well. That a specific causative micro-organism has not been demonstrated in no way invalidates this statement. One repeatedly sees an acute rhinitis develop in one member of a family and pass through the entire household of perhaps six or eight persons, adults and children. Infants and young children should not come in contact with other persons suffering from such conditions. Symptoms.—The onset is usually sudden, and characterized by sneezing and difficulty in breathing through the nose. This may continue for a few hours or, in some cases, for a day or two. At the expiration of this time a mucous, watery nasal discharge appears. Infants are the greatest sufferers, owing to the fact that breathing, which has to be carried on largely through the mouth, is rendered difficult, and nursing, in conse- quence, is frequently interrupted. A degree or two of fever may exist at the commencement of the attack, but any elevation of temperature, as a rule, lasts only a few hours. Neglected cases frequently become infected with pyogenic bacteria (staphylococcus, pneumococcus, and streptococcus), in which event a troublesome purulent rhinitis results. In the majority of the neglected cases, and in some of those that are well treated, the rhinitis is the beginning of an infection of the mucous membrane, which involves successively the fauces, tonsils, larynx, and bronchi. Repeated attacks doubtless contribute to the production of adenoid growths in the nasopharyngeal vault. Otitis media is not an infrequent outcome, particularly if the child has adenoids. Differential Diagnosis.—Acute simple rhinitis is to be differentiated from specific rhinitis, which is one of the first manifestations of congenital syphilis. When due to syphilitic infection the condition is uninfluenced by the usual treatment. There is no tendency for it to descend and involve the mucous membrane of the bronchi. The hoarseness of con- genital syphilis is persistent and of gradual development. Furthermore, if the rhinitis is due to syphilis, other diagnostic signs are present or will soon appear. Measles almost invariably begins as an acute rhinitis. The accom- panying conjunctivitis, the hard, dry, hacking cough, and the character- istic rash soon make the diagnosis possible. In nasal diphtheria there is invariably a discharge from the nose which may be differentiated from that of simple rhinitis by the fact that the discharge in diphtheria is excoriating in character and is often tinged with blood. A diphtheric discharge may be limited entirely to one nostril or may be greater from one nostril than the other; while in acute simple rhinitis the amount 306 ACUTE RHINITIS (CORYZA; SNUFFLES; COLD IN THE HEAD) 307 of the discharge is usually the same from both sides. Influenza begins with sneezing and nasal discharge, serous in character. In influenza, however, there is associated cough, fever, and more or less prostration. Duration.—The tendency of acute simple rhinitis in a strong child is toward recovery in five or six days. When the surroundings are un- favorable, or the child is delicate or rachitic, active treatment will be required to bring about a prompt recovery. Complications.—Simple rhinitis is very often the beginning of an infection which may reach the middle ear and produce purulent otitis or mastoid disease. Cervical adenitis is not an infrequent outcome. Retropharyngeal adenitis and retropharyngeal abscess, acute laryngi- tis, bronchitis, and bronchopneumonia may all result from acute rhinitis. Early treatment and care of the primary condition are, therefore, exceed- ingly important. Treatment.—The first step is the administration of 2 teaspoon- fuls of castor oil. During the initial stage of engorgement much may be accomplished for the very young by local medicaments. One of the best is menthol, \ grain, dissolved in 1 ounce of liquid petrolatum. Of this solution 3 drops should be instilled into each nostril every hour by means of a medicine-dropper. This treatment alone will relieve the patient of distressing obstruction and facilitate freer breathing. Older children may use a spray containing 1 grain of menthol to 1 ounce of liquid petro- latum at intervals of two or three hours. In case menthol and petrolatum are not at hand, melted white vaselin may be similarly employed. For internal use the following medication has served well. At least six doses should be given in the twenty-four hours. For a child three months of age: 1$. Tincturse belladonnse gtt. vij Pulveris camphorse gr. iv Sacchari lactis, q. s. M. div. et ft. tabellse No. xxx. Sig.—One tablet every two hours. Six months of age: 1$. Tincturse belladonnse gtt. x Pulveris camphorse gr. v Pulveris ipecacuanhse et opii gr. iv Sacchari lactis, q. s. M. div. et ft. tabellse No. xxx. Sig.—One every two hours in water. From one to two years of age: R. Tincturse belladonnse gtt. xv Pulveris camphorse gr. vj Pulveris ipecacuanhse et opii gr. x M. div. et ft. tabellse No. xxx. Sig.—One every two hours. From two to four years of age: Tincturse belladonnse gtt. xv Pulveris camphorse gr. vj Pulveris ipecacuanhse et opii gr. xv Sacchari lactis, q. s. M. div. et ft. tabellse No. xxx. Sig.—One every two hours. 308 THE PRACTICE OF PEDIATRICS If for any reason the tablets cannot be prepared, powders will answer the purpose equally well. The above prescriptions are indicated for the second or catarrhal stage, in which we usually find the patient on beginning treatment. We must guard against the constipating effects of the camphor and the Dover’s powder. In the treatment of nasal disorders the forcible use of the syringe, or any form of nasal irrigation which requires force, should be condemned. Infection is easily carried into the eustachian tubes, and may give rise to very grave complications. A suppurative otitis is thus very easily produced. An enema of warm sweet oil or soapsuds should be administered if the bowels do not move once in twenty-four hours. In treating chil- dren of a markedly constipated habit the Dover’s powder may be omitted. Internal medication, if begun early and properly carried out, will not be needed for more than two or three days. During an attack of acute rhinitis the child should not be unneces- sarily exposed to cold, owing to the strong tendency of the inflammation to descend and involve the deeper portion of the respiratory tract. Not- withstanding the undoubted good effects of open-air treatment in certain forms of pneumonia much harm is often done to children with incipient colds affecting the upper air passages by injudicious exposure to open window drafts in inclement weather. Caution in this respect will insure the proper procedure in a given case. CHRONIC RHINITIS (NASAL CATARRH) Nasal discharge, more or less constant, is present in not a few in- dividuals throughout childhood. In the majority of those affected this discharge begins with the onset of cold weather and lasts until spring. The secretion may be composed of thin, watery mucus, or it may be mucopurulent in character. Etiology.—In order to treat this condition successfully the source of the discharge must be discovered. It may be due to several causes, which are here given in the order of their frequency: 1. Adenoids in the nasopharyngeal vault. 2. Hypertrophy of the turbinate bones, with septal deviations and hypertrophy of the mucous membranes. 3. Infection due to pyogenic bacteria. When present, this may follow acute rhinitis, but is more often the sequel of one of the infectious diseases. The discharge may be distinctly purulent and is often very profuse. 4. Infection due to the Klebs-Loffler bacillus. A great many cases of this type in children under eight years of age have been observed, in which a serous discharge from one or both nostrils has persisted for a considerable period of time—in one instance for an entire year. Ex- amination of the discharge shows the presence of the Klebs-Loffler bacillus. Such children are not ill, and are brought to a physician solely for treat- ment of the nasal discharge. The cases do not clear up under ordinary methods of treatment, but promptly respond when from 1500 to 2000 units of diphtheria antitoxin is given. CHRONIC RHINITIS (NASAL CATARRH) 309 5. Hay-fever is characterized by a periodic discharge which may be said to be chronic in character, persisting over several weeks. 6. Malnutrition. A thin, watery discharge, apparently due to relaxed mucous membranes, occurs in weak and poorly nourished children with no other abnormal condition to explain the trouble than the general weak- ness. 7. Disease of the sinuses. Sinus infection of a mild type may cause persistent rhinitis without other symptoms, and these cavities should be examined in obscure cases. 8. Foreign bodies. A foreign body in either nostril will produce a persistent discharge. When a child is brought to us with a history of a persistent serous or purulent discharge from one nostril, we invariably examine for a foreign body, and repeatedly have found this discharge explained by the presence of a pea, a bean, a piece of coal, or a button. Illustrative Case.—At the Out-patient Department of the Babies’ Hospital a child three years of age was brought for treatment of a persistent right-sided nasal discharge which had existed for seven months. Examination showed a foreign body well up in the nostril. This object was removed with considerable difficulty and proved to be a piece of cork. In these cases of chronic rhinitis the possibility of adenoids (see p. 322) should never be forgotten; for their existence cannot be excluded because a child is not a mouth-breather and does not snore. A chronic “cold in the head” almost invariably indicates the presence of adenoid vegetations in the nasopharyngeal vault. Examination may reveal that the naso- pharyngeal space is blocked by the growth, so that entrance with the finger is almost impossible. In other instances only a small, pulpy mass will be found, or a ridge of soft, friable growth at the upper portion of the vault, not large enough to produce signs of obstruction, but actively se- creting and manifestly the source of the discharge. Children who have anterior nasal defects, such as hypertrophies of bone or thickening of the membranes, usually have adenoids as well. In fact, adenoids play no small part in most of the catarrhal affections of the upper respiratory tract in children, and an examination of a child with a nasal discharge or a cough which is difficult to explain is never complete without an explora- tion of the nasopharyngeal vault. Treatment.—The treatment consists in correcting the condition which causes the discharge. If adenoids are present in a sufficient amount to cause trouble, they should be removed (p. 325). No other treatment is of any avail. For deformities and hypertrophies of the anterior nasal structure operative measures are also essential, but should be carried out by one skilled in rhinoplastic work. Purulent rhinitis, primary or following the infectious diseases, is advantageously treated by a spray composed of liquid petrolatum, 1 ounce, ichthyol ammonium sulphate, 2 grains, the mixture being thoroughly shaken before using. This spray should be used every twro hours while the child is awake. Once or twice a day it may be well, if the secretion is profuse and purulent, to instil into the nostril about 20 minims of a 1 : 6 aqueous solution of hydrogen peroxid. If the Klebs-Loffler bacillus is present, antitoxin alone will con- trol the disease, and that very promptly. The anemic and poorly nourished patients, who show almost no ab- 310 THE PRACTICE OF PEDIATRICS normality, but suffer more or less from a constant serous discharge, are benefited by constitutional measures only—a dry climate, plain, nourishing food, iron, cod-liver oil, massage, and salt baths. Suitable management is referred to in detail under The Treatment of the Sub- normal Child (p. 140). Applied to such children, local treatment, apart from cleanliness, is a loss of time and energy. Non-traumatic nasal hemorrhage in a child usually occurs from one of two sources—adenoid vegetations in the nasopharyngeal vault or an erosion or ulceration of the mucous membrane covering the free vas- cular area of the anterior portion of the nasal septum. Treatment.—Hemorrhage due to adenoid growth is usually readily controlled by keeping the child in an upright position, or by the application of cold to the back of the neck—preferably by a piece of ice wrapped in a table napkin or by an ice-bag. When the hemorrhage is due to an erosion of the septum and pressure of the finger on the outer side of the bleeding nostril is found ineffective, the nostril may be packed with cotton saturated with a 5 per cent, solution of antipyrin or a 1 : 2000 solution of adrenalin. For permanent relief, and to prevent a recurrence of the hemorrhage, adenoids should be removed and an excoriated or ulcerated septum cauterized with a 50 per cent, solution of silver nitrate. If the ulcer is first cleaned with plain water, ordinarily but one or two applications of the silver solution will be required. Spraying the affected side with a 1 per cent, solution of ichthyol in liquid petrolatum will hasten the healing process. As the ichthyol is not soluble in the oil, the mixture should be well shaken before using. NASAL HEMORRHAGE PERSISTENT COUGH We have had occasion to examine and treat many children who were brought to us because of a “ cough ” which had not been controlled by the measures employed. The history is usually only that of a persistent cough. This may be irritating in character, keeping the child awake at night, or it may be paroxysmal, the attacks being more severe when the child is lying down. Many times the paroxysms are so severe, par- ticularly at night, that in the absence of chest signs, whooping cough is suspected. Types of Cough.—While we hear much of the cough of teething, the “stomach cough,” the “nervous cough,” and the “habit cough,” it has never been our lot to see a case in which the cough was not con- nected in some way with the respiratory tract. Thorough examination of these cases, perhaps repeated examinations, will be required before the site of the trouble is definitely located. Then it will invariably be found somewhere between the anterior nares and the diaphragm. The “stomach cough,” the “nervous cough,” or the “teething cough” fre- quently referred to by the older writers stood for the persistent cough which could not be accounted for by physical examination of the chest or by mere inspection of the throat. An adherent pleura and enlarged tonsils without adenoids are ac- PERSISTENT COUGH 311 countable for a very small number of these cases. An elongated uvula, to which these obscure coughs have also been attributed, is very rarely a cause. Adenoid Vegetations.—An immense majority of these obscure coughs in children are due to adenoid vegetations, with or without enlarged tonsils. A child with such a cough may have the typical adenoid face, mouth-breathing, and other signs referred to (see Adenoids, page 323), or these symptoms may be entirely absent. It is the latter type of case that is particularly puzzling and apt to be overlooked. On account of the absence of mouth-breathing and other symptoms of nasal obstruc- tion, the possibility of adenoid vegetations is often ignored. In these cases careful inquiry will usually elicit the history of frequent colds, or what is styled “catarrh” (as there is more or less serous discharge from the nose), or the statement that the child “takes cold in the head easily.” Digital examination of the nasopharyngeal vault will reveal a fringe of soft adenoid growth at the upper portion of the posterior pharyngeal wall, not large enough to produce obstruction, but actively secreting. This secretion, if not profuse, is partially evaporated in the nostrils, or if pro- fuse, is discharged from the nostrils or passes backward over the posterior pharyngeal wall, thus provoking cough, when the child is up and about. When the child rests on his back, the secretion naturally flows over the posterior pharyngeal wall, and induces cough. Time and again one may relieve the most obstinate cough by cureting and removing this sponge- like tissue. Illustrative Case.—In the case of one patient, a boy two years of age, who had been coughing hard for ten days with paroxysms and vomiting, a diagnosis of pertussis had been made both by a member of the family who had seen many cases of whooping- cough, and also by the writer. Adenoids were found to be present in a slight degree. Their removal was accomplished, with the idea of making the coughing attacks less severe, when, greatly to our surprise, the coughing ceased at once, not a paroxysm occurring after the growth was removed. The cough was due to the adenoid vege- tations and not to pertussis. Adherent 'pleura, non-tuberculous, as previously mentioned, is occa- sionally a cause of persistent cough. Autopsies upon children who have died with non-respiratory diseases often show these pleuritic adhesions, which are not suspected during life. Illustrative Case.—A girl twelve years of age was brought because of a persist- ent cough. The child was otherwise well and gaining in weight. She had been treated with expectorants, cod-liver oil, and the usual other medication, without avail. The cough remained unchanged and was influenced only by opiates. A very careful physical examination revealed friction rales, covering an area the size of a half-dollar, at the base of the right lung, adjacent to the spine. They were heard only on forced inspiration and had been overlooked in the previous examination. The case had been diagnosed as one of “nervous cough.” Tracheal Cough.—Tracheitis will produce a severe and intractable cough, with no signs in the chest. These cases frequently follow attacks of true influenza, or the cough may be present during the active period of the disease. If the child is old enough, he will aid us by referring to the sense of discomfort and tightness which exists over the upper portion of the chest. Sometimes the sensation will be described as a burning which is located directly over the trachea. 312 THE PRACTICE OF PEDIATRICS Enlarged Mediastinal Glands.—Children with enlarged tracheobronchial lymph-glands are particularly subject to persistent cough which frequently assumes a spasmodic, even sneezing type strongly suggestive of pertussis. At times the adenitis is tuberculous, but not infrequently it is the result of prolonged bronchitis or bronchopneumonia of the influenzal or strep- tococcic type, one of the characteristic late results of such infection being considerable peribronchial thickening. In identifying enlargement of glands in the midchest region prolonged slight elevation in temperature, percussion dulness, and a positive D’Espine sign are of significance, but the most reliable aid is afforded by the x-ray combined with the intradermal tuberculin test. Irrespective of the exact nature of the infection the treatment most effective is the placing of the patient in a climate where sunshine pre- dominates and colds are infrequent. Tuberculosis.-— Incipient tuberculous infiltration in any portion of the lungs or pleura may produce persistent cough. Thorough physical examinations and careful observation of all the cases, with the intradermal test, will make a diagnosis possible. Pertussis without the whoop or vomiting may cause a persistent cough, spasmodic in character. It runs its course and subsides in from four to eight weeks. A diagnosis is possible only when there is a history of exposure to the disease, or when another member of the family has an unquestionable attack. Foreign Body Cough.—This type of cough has been given the importance which is its due by the notable work of Chevalier Jackson and his followers, which has demonstrated beyond argument that in all cases of unexplained cough the presence of a foreign body in the air passages must be considered until the existing facts are shown by x-ray examination. The facts are not always apparent to the untrained interpreter even with the aid of the x-ray, but the whereabouts not only of opaque but of transparent objects, such as peanut kernels and seeds, may be detected by the expert. Upon the removal of the foreign body by the aid of the bronchoscope the focus of inflammation in the lung (often in spite of previous long dura- tion) usually undergoes spontaneous resolution and the cough ceases. Many children have been wrongly called tuberculous for lack of dis- cernment by their physicians in cases of respiratory obstruction from foreign bodies. (See Foreign Bodies in the Air-passages, p. 818.) The treatment of the various conditions producing cough is referred to under the respective headings. In order to examine the throat of a young child quickly and thor- oughly it is necessary that he be held in a proper position in front of and at the right side of the attendant, supported by her left arm beneath the buttocks. Her right arm, which is thus left free, is passed around the child, binding his arms to his sides. The child’s head rests against the shoulder of the attendant. The physician places his left hand on the child’s head to steady it, and with the tongue-depressor or teaspoon in his right hand, with the child in perfect control, presses the tongue downward so that it will not obscure the field of vision. In handling an older and Throat Examination SIMPLE PHARYNGITIS 313 stronger child, it is best to bind the arms to the sides with a large towel or small sheet. The most satisfactory view can be obtained by daylight before a window. If the examination is made in the evening, a lamp or taper held by a third person, a little above and behind the attendant’s right shoulder, will furnish satisfactory illumination. The head-mirror should be used for children who are too ill to be taken out of bed, the reflection from a lighted lamp or candle being sufficient. The various electric devices which may be carried in the pocket are very useful. FAUCITIS By the term “faucitis” we understand an inflammation of that por- tion of the mucous membrane of the buccal cavity situated posteriorly to the soft palate and the anterior pillars of the fauces, including both the anterior and posterior pillars, the tonsils, and the pharyngeal vault. The inflammatory process is superficial, involving the mucous membrane only, so that the tonsils are involved only to the extent of the mucosa. Faucitis is always present in scarlet fever, usually to a marked degree. In measles it is also present, but less intense in its manifestations. Its most frequent appearance is in connection with a summer cold. Every year, in late May and June, we are called upon to treat many such cases. The symptoms always comprise cough, which is dry and ineffective, and a slight fever—from 100° to 101° F. The child complains of sore throat, and has some discomfort on swallowing. Upon inspection an intense inflammation will be noticed, involving the entire visible mucous mem- brane. In many cases the inflammation extends downward and involves the larynx, which fact will be indicated by the hoarse, croupy character of the cough. The condition is usually the result of a mixed infection, with the streptococcus predominant. The entire illness is ordinarily of three or four days’ duration. Treatment.—The condition is best relieved by a purgative of rhu- barb and soda—3 grains of powdered rhubarb and 3 grains of soda for a child from two to five years of age. To a child under two years of age 1 to 3 grains of rhubarb and 1 to 2 grains of bicarbonate of soda may be given. This, in the case of a child from one to three years of age, is fol- lowed by a tablet or powder of tartar emetic, 1/90 grain, powdered ipecac, 1/60 grain, and chlorate of potash, 1 grain, at two-hour intervals. Older children, three years and over, receive 2 to 3 grains of chlorate of potash, 1/90 grain of tartar emetic, and 1/40 grain of ipecac at two-hour intervals —six doses in twenty-four hours. SIMPLE PHARYNGITIS Inflammation limited to the posterior pharyngeal wall is of rather infrequent occurrence in young children. When thus affected, the parts present a reddened, granular appearance. In the cases which have come under our observation such a condition has always been associated with digestive disturbances. The tongue is usually coated and the breath foul. A dry cough and frequent attempts at clearing the throat are the usual symptoms. The temperature is rarely above 101° F. The condi- tion is to be distinguished from the pharyngitis which occurs as a result 314 THE PRACTICE OF PEDIATRICS of microbic infection, in that only the posterior wall is involved. The tonsils and pillars of the fauces and the soft palate present a normal ap- pearance. Treatment.—The treatment is to reduce the diet for a few days to cereal gruels—barley, rice, or wheat—and chicken or mutton broth. Calomel, 1/10 grain, with 1 grain of rhubarb, given after feedings, three times a day for three days, will often promptly relieve the condition. THE TONSILS Anatomically, the lymphoid structures in the pharynx, termed “ton- sils,” consist of several groups. Of these, the faucial and pharyngeal structures are clinically of most importance. The faucial tonsils are situated one on each side of the oropharynx, between the anterior and posterior pillars of the fauces. The tonsil is roughly ovoid, and in early life about 2 cm. thick, the longest measure- ment being the vertical diameter. The inner surface presents many depressions or crypts. These are most numerous in the upper portion. Above the organ there is a larger depression called the supratonsillar fossa. This frequently serves as a pocket for the development of sup- purative inflammation. On its outer surface the tonsil is covered by a fibrous capsule, from which the reticulum of connective tissue sup- porting the lymphoid structure is derived. In close relation to this sur- face is the ascending palatine artery. The internal and external carotid arteries are normally about 2 cm. distant, but as a result of inflammation and hypertrophy in the tonsils, these vessels may be less remote. Branches to the organs are derived chiefly from the ascending pharyngeal and facial arteries, but also from the lingual and descending palatine. Hemorrhage following operations arises principally from the ascending palatine, the ascending pharyngeal, and tonsillar branches of the facial. Operative wounds of the carotids are very rare. The pharyngeal tonsil is a single structure, occupying the posterior- pharyngeal wall. According to Piersol, without being markedly hyper- trophied, it may encroach upon the nasopharyngeal space. The tubal tonsils and the lingual tonsils are developed respectively at the eustachian orifices and over the posterior third of the tongue. Scattered collections of the same tissue unite with the larger masses described, and form an irregular guardian-ring encircling the upper part of the pharynx. ACUTE FOLLICULAR TONSILLITIS Tonsillitis consists in an inflammation of the mucous membrane and glandular structure of the tonsil. Age.—No age appears to be exempt, the condition at times develop- ing in infants three or four weeks old. The great majority of the cases, however, occur between the second and twelfth years. Etiology.—Tonsillitis is due to a mixed infection, usually with the streptococcus predominating. The disease is infectious, and frequently occurs in epidemics. ACUTE FOLLICULAR TONSILLITIS 315 Predisposition.—One attack prediposes to another by preparing a suitable culture-field in the crypts. Children in whom lymphatism is prominent, and whose glandular structure possesses a poor resistance, are the most susceptible. Pathology.—The tonsils undergo considerable enlargement, and the crypts become filled with exudate consisting of epithelial detritus, mucus, pus, and bacteria. Occasionally the exudate covers the surface of the organ in the form of a pseudomembrane similar in appearance to that occurring in diphtheria. The pathogenic bacteria most frequently present are the streptococcus, staphylococcus, and pneumococcus. Of these, the streptococcus is so frequently a cause of the inflammation that in many epidemics the term “tonsillitis” has been superseded by the convenient designation, “streptococcus sore throat.” When the cellular infiltration in the depths of the tonsil becomes extreme, suppuration and abscess- formation, combined with severe edema of the peritonsillar tissue, is not uncommon. If the discharge of such a collection of pus is not spontaneous or else obtained by early incision, complete destruction of the parenchyma and the formation of a retropharyngeal abscess may result. Symptoms.—The onset of tonsillitis is usually sudden and may be attended by a chill. In a few of our cases an attack has been ushered in by convulsions. However, the usual mode of onset is with fever— 101° to 103° F.—headache, loss of appetite, and muscular soreness. Young children may show difficulty in swallowung, and older children may com- plain of pain in the throat. Not every case of tonsillitis, however, is char- acterized by the existence of such pain. Inspection shows that the tonsils are swollen and reddened and perhaps covered with scattered, light- colored, cheesy deposits. In some instances the local signs consist only of the swelling and redness; in other cases the cheesy deposit exists as an early manifestation. The spots of exudate may remain distinct and single, or they may coalesce, forming a pseudomembrane. During the attack the patient feels decidedly ill, and often gives evidence of considerable prostration. The temperature ranges from 103° to 105° F. Slight swelling may occur in the lymphatic glands at the angle of the jaw, but this is usually absent. In a comparatively small percentage of cases the asso- ciated adenitis is very pronounced. A great deal of tenderness of the glands, with a sore throat, is a suspicious sign, and should lead one to examine very carefully for diphtheria. Duration.—An uncomplicated attack of tonsillitis lasts from three to five days. If the temperature continues for a longer period than six days, the possibility of complications should be considered. Prognosis.—The prognosis is favorable. When uncomplicated, the disease is never fatal. Complications.—Cervical adenitis, otitis, peritonsillar abscess (quinsy), and retropharyngeal abscess are the most frequent secondary conditions. Infrequent complications are arthritis, endocarditis, pericarditis, and pye- mia. Acute nephritis is occasionally a sequel of tonsillitis and is apt to assume a hemorrhagic character. Differential Diagnosis.—Tonsillitis must be differentiated from tonsil- lar diphtheria. There are few harder problems, and, in fact, in many cases, early in the attack, the solution is impossible without a bacterio- 316 THE PRACTICE OF PEDIATRICS logic examination. The following characteristics of the average case of each of the two diseases may aid us in differentiating: Tonsillitis.—Onset sudden; fever high at onset—102° to 105° F. Glands at the angle of the jaw swollen slightly, if at all. Exudation, follicular, appearing as small dots; may form membrane through coales- cence. Tonsillar Diphtheria.—Onset gradual; fever usually low at onset, 100° to 102° F. Lymphatic glands at the angle of the jaw considerably swollen. Membrane present on the tonsil appearing in thin, grayish layers which gradually become thicker and more extensive. Mixed Infection.—A case of mixed infection may at first present the picture of typical tonsillitis. The temperature may vary from 103° to 105° F. Pain upon swallowing, prostration, and loss of appetite may exist together with a follicular exudation. Such a case may remain stationary for twenty-four to forty-eight hours. The dots then coalesce, forming a firm membranous deposit, the lymph-nodes at the angle of the jaw enlarge; and, in short, both the clinical manifestations and the bacteriologic examination show that we have to deal with a case of diph- theria. These cases of diphtheria which are preceded by a clinical tonsillitis are probably the most dangerous. The primal condition is diagnosed as tonsillitis, and for several days is considered to be only a tonsillitis in spite of the membranous deposit which later forms. This delay in making the diagnosis gives abundant opportunity for the exposure of other children, and postpones the use of antitoxin, rendering the remedy, when finally given, of little or no avail. The only safe rule is to consider as diphtheric every case in which there is a pseudomembrane on the tonsils, and to treat such a case with antitoxin without waiting for a bacteriologic examination. Furthermore, when there are other children in the family, one should invariably isolate every case of simple tonsillitis. Treatment.—Local treatment of the diseased parts in tonsillitis by spraying, swabbing, and painting has been of very little service in our hands, particularly in dealing with children under four years of age. When the patient is held by force for such treatment, thoroughness is impossible, and little or nothing is accomplished. For tractable children and those old enough to understand what is being done, gargles, sprays, and irrigations are useful in so far as they relieve pain and cleanse the diseased parts. A useful gargle is the following: I). Sodii salicylatis, Sodii biboratis, Sodii bicarbonatis aa gr. xlv Essentise menthse piperitse 5j Aquae q. s. ad. 3ij M. Sig.—One teaspoonful in one-half glass of water at 115° F. Gargle entire quantity every hour. A useful spray is the following: 1$. Acidi borici gr. lx Aquae menthae piperitae 3 viij M. Sig.—Spray throat every two hours. In severe tonsillitis associated with much swelling and consequent tension, the pain upon swallowing is often excruciating. Irrigation of ACUTE FOLLICULAR TONSILLITIS 317 the throat is indicated not only for purposes of cleanliness, but because of the relief from pain which it affords. The technic recommended is described on page 321. The child with simple tonsillitis may receive the irrigation sitting erect. If found accept- able this may be repeated in four to six hours. It is advisable to begin the general treatment with a laxative. One grain of calomel, in divided doses of grain every fifteen minutes, answers well. The food should be reduced. For a bottle-fed patient one-half the quantity of the usual milk mixture should be given, diluted with an equal quantity of water. The fever, if high, may be readily controlled by cool sponging. The only drug which has appeared to possess any signal value for internal use in tonsillitis is chlorate of potash given in the dosage of 1 Fig. 59.—Cold compress in position. grain at two-hour intervals for a child one year of age; 2 grains at two- hour intervals for a child two years of age—16 grains in twenty-four hours; 3 grains at the same interval for a child three years of age—24 grains in twenty-four hours. We rarely give more than 3 grains at two- hour intervals at any age, although we have never been able to associate the action of the drug with kidney complications in any of hundreds of cases. This drug is usually given in solution with simple elixir and water or syrup of raspberry and water. Children who have repeated attacks of tonsillitis should have the tonsils enucleated regardless of their size, as diseased tonsils are portals of infection and a source of ever-present danger. Cold compresses (Fig. 59) applied to the throat are of aid to older children, who can appreciate the necessity of this measure. This form 318 THE PRACTICE OF PEDIATRICS of treatment is described in detail under the management of acute catarrhal laryngitis. (See p. 333.) PERITONSILLAR ABSCESS (QUINSY) The seat of a peritonsillar abscess is in the cellular tissue about the tonsil, and the condition is due to an invasion of the parts by patho- genic bacteria, among which the streptococcus is most frequently present. The source of the infecting agent is almost invariably a tonsil more or less diseased. The abscess may form above, in front of, or behind the tonsil. Quinsy is usually preceded by recognizable tonsillitis. In none of our cases has the abscess followed diphtheria, scarlet fever, or measles. Symptoms.—The child has tonsillitis with the usual symptoms, and, in addition, greatly increased swelling of the throat and pain upon swallow- ing. He complains of pain in the muscles of the neck on the affected side, and holds the head toward that side. A fairly early symptom is inability to open the mouth to the usual extent. In the average case inspection reveals a reddened, edematous swelling, slightly above and in front of the tonsil, causing a forward displacement of the uvula. Exceptionally, when the swelling develops posteriorly, the tonsil is displaced forward and appears unduly prominent. A case of this type is very apt to be over- looked unless a digital examination is carefully made, when a soft, fluctu- ating swelling will readily be felt behind the tonsil. Speech is interfered with, and the act of swallowing is carried out with great discomfort. Young patients will go for several days with little or no nourishment because of the pain occasioned by the taking of food. Treatment.—The treatment is incision. This step, however, should not, as a rule, be taken until the abscess is fully developed. If the in- cision is made too early, it not infrequently becomes closed and requires reopening. This closure sometimes occurs even after a timely opera- tion, because when too small an incision is made, the contraction of the abscess wall necessarily following the free discharge of pus and blood effectually closes the opening. In exceptional cases the development of dyspnea may be rapid, and in such instances prompt incision over the most prominent part of the presenting swelling must be made even though the actual location of pus is not demonstrated. If the scalpel penetrates to sufficient depth and the incision is enlarged with an artery clamp relief afforded will justify this more radical course, whereas delay might necessitate tracheotomy. For operation the patient should be wrapped in a large towel or sheet with the arms securely bound to the sides. He should sit in an upright position on the lap of the attendant, against whose right shoulder his head rests. The left arm of the attendant is passed around the patient, holding him firmly, while the right hand grasps his forehead. A Denhard gag of the O’Dwyer set may be used to hold the mouth open. Either by the use of reflected light from a head-mirror, or with the patient facing a window, the operator, using a guarded bistoury, makes a free incision in the abscess from above downward. The escape of a considerable amount of blood usually follows the withdrawal of the knife. Frequently more blood than pus is discharged. This is particularly apt to be the case if Vincent’s angina 319 the abscess is opened early. The use of light ether anesthesia is at times desirable, in which case the child’s head must be kept low and turned to one side to prevent aspiration of the liberated pus, and consequent asphyxia. It is interesting to note that the cases which open spontaneously rarely heal spontaneously. After a free incision it is advisable during daily visits immediately after the operation to prevent a closure of the wound by passing into it a director, moving this up and down to break up any beginning granulations. With free, uninterrupted drainage the patient is usually well in from three to five days. With the exception of a saline laxative, which should be given early in the attack, internal medication is valueless. Two drams of Rochelle salts or 6 ounces of a solution of citrate of magnesia may be ordered. Other treatment is directed to the comfort of the patient. An ice-bag applied externally before operation may be acceptable. Our greatest means of relief, however, is afforded by the use of the hot saline irriga- tion, and the hot gargle where practicable. But few children can gargle well, however, so that ordinarily this measure is best dispensed with. With the few cases where it is practicable, the following prescription and method has been of service: 1$. Sodii bicarbonatis gr. xlv Essen tise menthse piperitae 3j Aquae q. s. ad. §ij M. Sig.—Add 1 teaspoonful to 6 ounces of water at 120° F. and gargle entire quantity every half-hour. The pain occasioned by gargling is another objection to its practice by children. The more effectual means of relieving pain, which causes no effort nor distress whatever, and gives astonishing relief, is a saline irrigation prepared and given as described on page 321. The irrigation may be repeated every hour and may be used as well after as before operation. When once the child experiences the relief afforded, there will be no trouble in repeating the irrigation. In Vincent’s angina there is an ulceration of the tonsil of varying size which may involve the whole tonsil or a very small portion. The shape of the ulcer is irregular with overhanging edges in advanced cases, in appearance not unlike a syphilitic lesion. The ulcer is of varying depth, usually not more than \ inch at the deepest part. The sloughing base gives the appearance of a membranous deposit. In mild cases in which the ulcerative process is slight the lesions may present only the appearance of grayish cobweb-like patches. Etiology.—Vincent’s angina is an infection in which two forms of parasites may be isolated, one a fusiform bacillus and the other a spiril- lum. They are always associated. These are also found in many cases of ulcerative stomatitis. The bacillus is a slender rod measuring from 6 to 12 n long, pointed at each end, Gram negative, and is not motile. The spirillum generally has from three to ten convolutions, is actively motile, and Gram negative. VINCENT'S ANGINA 320 THE PRACTICE OF PEDIATRICS The organisms sometimes appear in a mixed infection with diphtheria. They may be cultivated anaerobically on ascitic agar at 37.5° C.1 Symptoms.—The symptoms are not at all severe, usually a slight rise in temperature, 100° to 102° F., with perhaps moderate swelling of the lymph-nodes on the affected side. There is often an accompanying stomatitis which may be the trouble for which the physician is consulted. That there is an involvement of the tonsil is first discovered during the examination of the patient. Very severe and fatal cases have been re- ported, but these are surely very unusual. Diagnosis.—The case may resemble diphtheria sufficiently to require that a culture be made. A differential diagnosis is usually readily made by a microscopic examination of a smear from the ulcer. Treatment.—The medical treatment is the same as for tonsillitis. If there is adenitis, a cold compress (p. 333) should be applied. Locally, tincture of iodin, peroxid of hydrogen, or a weak watery solution of sal- varsan applied twice daily to the ulcer appears to shorten the duration of the disease. SEPTIC SORE THROAT (MILK BORNE)2 Epidemic sore throat due to an infection conveyed by milk has been of frequent occurrence in England for a number of years. Since the Boston epidemic in 1911, visitations of the disease have been reported from various sections of this country. Doubtless out- breaks had previously occurred, but had not been recognized. In a recent epidemic of 40 cases there was a mortality of 15 per cent. Age.—All ages are susceptible, the greatest number of cases occur among the young. Etiology.—In the Boston epidemic of 1911 it was first conclusively demonstrated in this country that septic sore throat is a distinct clinical entity due to the streptococcus conveyed in a polluted milk supply. During this time, and at subsequent outbreaks, an examination of the milk source led to the discovery of an epidemic of mastitis existing among the cows supplying the infected community, pus-cells being found on several occasions in the milk. That the dairyman acting as a human carrier is also a factor in infecting the milk has been proved bj" the exist- ence of a number of cases of sore throat among dairy employees, one of whom (in an epidemic) supplied an abundant growth of almost pure streptococci. Pathology.—A general redness may be diffused over the pharynx, tonsils and soft palate, simulating the aspect of a scarlet fever throat. Small isolated patches of exudation in the tonsillar crypts may make the condition resemble an acute follicular tonsillitis. Later an extensive pseu- domembranous exudate may strongly suggest diphtheria. Both tonsils may be involved simultaneously, but more frequently one is infected before the other. The cervical lymph-nodes are always involved to some extent and occasionally very much swollen, undergoing suppuration in the severe cases. The extension of the inflammation to the deeper tissues about the neck often leads to diffuse cellulitis of that region. 1 Tunnicliff, Jour, of Infec. Dis., 3, 1906. 2 Herman Biggs, New York Medical Record, 1915. SEPTIC SORE THROAT (MILK BORNE) 321 Symptoms .—The onset of the septic sore throat is fairly uniform in its manifestations, being usually sudden and attended by a chill. Nausea is also a frequent accompaniment of the early stages. The temperature rises rapidly to 103° or 105° F., and in the more toxic cases there is general muscular pain and soreness and severe headache. A marked degree of prostration is present in the severe cases. The first period of the disease lasts from three to five days. Rapid recovery may follow or complica- tions which may be numerous and dangerous may ensue and prolong the duration indefinitely. Complications.—Cervical adenitis with possible suppuration, and otitis media are the most frequent secondary conditions in the young. Peritonsillar abscess, nephritis, polyarthritis, pneumonia, and peritonitis are occasionally seen, especially in those more advanced in years. Prognosis.—The prognosis is better in children and young adults than in those who are older, due to the fact that the young enjoy a com- parative freedom from the complications. The mortality in recent epi- demics according to the literature has varied from 2 to 5 per cent. Prophylaxis.—Pasteurization of all milk used for drinking purposes will prevent the disease. Dairy employees should be under careful medical supervision. Treatment.—The treatment suggested for tonsillitis should be car- ried out, together with throat irrigation and supportive measures. Irrigation of the Throat Indications.—In cases of peritonsillar abscess, retropharyngeal abscess after operation, or sloughing ulcerative processes in the throat, such as we see in diphtheria rarely, but with comparative frequency in scarlet fever, irrigation of the throat with hot normal salt solution is of distinct therapeutic value. The relief to the pain, particularly in quinsy before operation, is sufficient to warrant this treatment. Those who have thus treated the fetid, sloughing throat of scarlet fever, for example, need no argument as to the possible advantages. Gargling is a measure of very limited usefulness even for those children who do it well, for the reason that the solution employed scarcely comes in contact with the post- pharyngeal wall and the lateral faucial structures. For a great majority of older children, and all young children, such a method is practically useless so far as the cleansing of the deeper faucial structures is concerned. Cervical adenitis, acute, suppurative, or chronic, is usually the direct result of throat infection. Acute suppurative otitis is almost always due to throat infection. An important means of preventing these conditions, with their distressing consequences, is an effective throat toilet. Often in scarlet fever not a small part of the systemic infection after the third or fourth day is through the throat. The irrigation should be done two or three times a day as follows: Procedure.—The child is wrapped in a sheet, which is securely pinned, binding his arms to his sides. He rests on his right side, without a pillow. Directly under his mouth is a pus-basin to catch the outflow. A new fountain syringe, containing a hot salt solution, 120° F., is suspended about 3 feet above the child’s body. The largest size of the hard-rub- ber rectal tip is fastened to the pipe and the tip is placed between the 322 THE PRACTICE OF PEDIATRICS child’s teeth. The current, interrupted every few seconds, should be forcible enough to increase its efficacy as a cleansing agent, the volume of fluid being so small that no inspiration of the water occurs. The first irrigations will arouse more or less rebellion on the part of the patient, and but \ pint of the solution need be used. With older children no trouble will be experienced after the relief afforded by the first irrigation is appreciated. In treating refractory young children, from two to four years of age, the assurance that there will be no pain and a promise of reward, will reduce the struggling to a minimum. It is not to be expected that the child will not cough; in fact, a moderate amount of coughing is desirable, as it dislodges the pus and sloughing tissue, allowing the solution to cleanse the parts more effectually. ADENOIDS The importance of adenoid growths as a cause of nasal obstruction has been appreciated only during the past thirty years. The vegeta- tions were first described by Dr. Wilhelm Meyer, of Copenhagen, in 18G8. Etiology.—In proportion to the population, the growths are as fre- quent among the wealthy and well-to-do as among the poorer classes. In fact, if the throats of all children were carefully examined with the finger, adenoid vegetations in the nasopharyngeal vault would be found in 95 per cent, of the cases. This, however, does not mean that 95 per cent, of children should have the adenoids removed, as in some instances the growth is very small and fairly innocent. We find adenoids not only in the delicate and ailing but also in the strong and well. Among hundreds of cases few are seen in which a part in the production of the growths can be attributed to lymphatism. The fact that adenoids are so generally prevalent among all classes and conditions of children points to common causative agencies: First: There is a tendency to overgrowth of lymphoid tissue in all children. Second: The location of the normal lymphoid tissue in the pharyn- geal vault subjects this tissue to the irritation of dust and sudden currents of cold air, resulting in the pathologic changes described. Third: The first and second conditions prepare the parts for the action of the third factor—infection. A curved probe tipped with sterilized cotton when passed into the adenoid tissue of any child, whether the amount of tissue is small or large, will afford a culture of the secretion, in which may be found the streptococcus, staphylococcus, pneumococcus, influenza bacillus, and many other pathogenic organisms. The local congestion caused by the presence of hordes of bacteria further increases the hypertrophy of the adenoid mass. Heredity is of no immediate consequence. If a new race of children could be born free from adenoid antecedents, they would just as surely develop the growths. Age.-—If a child passes the fourth year without adenoids, he will probably not acquire them later. Children are born with adenoids. At what period in utero they develop is not known. They may be seen 323 ADENOIDS at birth in infants with cleft-palate. Adenoids were present, in quite con- siderable amount, in one infant wrho was one month premature. Signs of the growths do not ordinarily develop before the end of the first year. The great majority of cases come under observation between the eigh- teenth month and the fifth year. At times, however, it is necessary to operate upon infants in order to give relief from growths which almost completely block the nasopharyngeal vault. Pathology.—Hypertrophied adenoids exist as overgrowths of the lym- phoid tissue normally present in the nasopharynx. When the lymphoid elements alone are increased, the growths are soft and spongy, but when, as is frequently the case, there is marked development of fibrous tissue, they are firm and resistant. Increase in the connective tissue is primarily a perivascular process. Ultimately atrophy of the lymphoid tissue occurs, resulting in contracture of the adenoid mass. This change has been commonly attributed only to late childhood and early adult life. Such changes, however, are not uncommon in the very young. The spontaneous abatement of symptoms which is so frequently observed in young adults is more probably due to increase in the capacity of the epipharynx than to actual diminution in the size of the obstructing mass. Symptoms.—Some children have large, roomy nasopharyngeal vaults, while in others, on account of the high palatal arch and the prominence of the bodies of the vertebrse, this space is very small. In the latter cases a very small amount of adenoid tissue causes marked obstruction. The character and amount of the growth likewise determine the degree of inspiratory impairment and the severity of the related symptoms. Mouth-breathing.— In all cases showing a considerable growth, and in others in which a moderate growth exists in a srhall vault, mouth- breathing occurs because the natural respiratory tract is partially blocked. Rhinitis.—A more or less persistent rhinitis is also present, and this is inteimittent—now better, now worse. It is usually worse during the winter. During the summer in some cases it may disappear, only to return with the first cold weather. In other cases, with considerable adenoid growth, the nasal discharge never ceases, but is apt to be worse during the winter and spring months. The child cannot blow the nose, the voice and speech are defective, and the voice has a nasal quality. Certain letter sounds, such as “n” and “m” in the words “spring” and “climb,” are pronounced with difficulty. Because of the presence of the mechanical obstruction in the natural respiratory passage, the child breathes through the mouth not only when awake, but when asleep, consequently snores, and is noisy and restless, tossing about and as- suming all sorts of awkward positions during sleep. Adenoid Face.—These children all have the characteristic adenoid face. The term “mouth-breathing” does not describe the condition ap- parent in a pronounced case in an older child. The masseters become so relaxed that a habitual drop jaw results. The nostrils are usually small; the nasolabial folds are deepened. Adenoids Without Facial Deformity.—In a child with a roomy vault, adenoids in small or medium-sized masses may be present without pro- ducing facial deformity or obstructive symptoms. 324 THE PRACTICE OF PEDIATRICS Apart from the characteristic appearance of the patients two symp- toms in particular suggest adenoids: First: Persistent rhinitis, indicated by habitual nasal discharge, which is ascribed to a chronic cold. Second: Cough, habitual, mild, or severe. It may be paroxysmal, often being confused with whooping-cough. (See p. 311.) The cough is always worse when the patient is lying down. Many of these cases pass unrecognized, adenoids being unsuspected because of the absence of obstructive signs, while the cough is attributed to the stomach, denti- tion, worms, nervousness, etc. Diagnosis.—The open mouth (see Fig. 60), the snoring at night, the stupid expression, the disturbed articulation, the persistent nasal Fig. 60.—Adenoid face. discharge, the deafness, the inability to blow the nose, the cough, and the chronicity of the symptoms all combine to make a picture afforded by no other condition. Method of Examination.—In children, after the fifth or sixth year, satisfactory examination by means of mirrors and illumination is oc- casionally possible. Occasionally a rhinologist will state that he is able to make all necessary examinations in much younger children by means of posterior rhinoscopy. We have never seen this actually demonstrated. Although such procedure is disagreeable to the patient, we prefer the finger examination in all cases. The child is securely held by an attend- ant, with the arms pinned to the sides. A mouth-gag or tongue depressor is then placed between the teeth, at right angles to the jaw, and held in HYPERTROPHIED AND PERMANENTLY DISEASED TONSILS 325 position by the left hand of the examiner, thus allowing the right finger to be free for the examination. Association with Enlarged Tonsils.—In the very young, adenoids usually exist independent of enlargement of the tonsils. The older the child, the more frequent is the involvement of the tonsils. Enlarged or diseased tonsils without adenoids are found only with the greatest rarity. Treatment other than by operation is highly ridiculous. HYPERTROPHIED AND PERMANENTLY DISEASED TONSILS Chronic enlargement of the tonsils is usually the result of repeated attacks of tonsillitis. Notwithstanding this fact, we have repeatedly seen enlarged tonsils which had never been clinically recognized as in- flamed. A tonsil is considered abnormally large when it extends beyond the pillars of the fauces. Enlarged tonsils not only produce mouth breathing, faulty articulation, and catarrh of the eustachian tube, but are doubtless a factor in the etiology of adenoids. Without being enlarged a tonsil may still exist as a menace to the owner. The very small tonsil which is badly diseased, and the small, deeply buried tonsil, largely covered by the pillars, are sources of great danger. In the crypts—whether the organ is large or small—are har- bored myriads of bacteria capable of producing repeated attacks of acute inflammation. The streptococcus, staphylococcus, colon bacillus, pneu- mococcus, the tubercle bacillus, and the Klebs-Loffler bacillus all abound. The crypts of diseased tonsils unquestionably may supply the infective agent in pericarditis, endocarditis, nephritis, anemia, and the various tox- emias classified under the broad term of “rheumatism.’’ Adenitis, both tuberculous and simple, is very rare in children who do not have foci of disease in their throats or teeth. The Necessity for Operative Interference in Cases of Diseased Ton- sils and Adenoids.—The simple indication to relieve mechanical ob- struction is by no means the sole criterion in advising operative measures. Diseased tonsils are responsible in no small degree for many of the com- plications attending other diseases. In influenza, diphtheria, scarlet fever, and measles the throat always shows active participation. A child free from adenoids and diseased tonsils presents greatly increased resistance to all these diseases; and complications in such children, par- ticularly as relates to the lymphatic glands and ears, are most unusual. During even a common cold, however, a mass of adenoids in the vault serves as a very efficient means of conveying infection to the middle ear. A small percentage of middle-ear cases develop mastoid disease; and a still smaller percentage, sinus thrombosis, with or without jugular involvement. In advising parents the physician should clearly portray the culture field which the child may be maintaining in the upper respiratory tract. Operation for Permanent Relief.—Various methods have been devised, all of which have their enthusiastic adherents, for the removal of enlarged tonsils and adenoids. For a discussion of these methods and their relative merits the reader is referred to works dealing with the surgery of the nose and throat. 326 THE PRACTICE OF PEDIATRICS Certain facts relating to the conduct of this operation are worthy of emphasis from the standpoint of the pediatrist, of which the following may be mentioned: Operation is contraindicated, except in urgent cases, during the preva- lence of an epidemic of a respiratory disease and whenever the patient shows evidence of bronchitis or extreme throat congestion. The preparation for the operation should include abstinence from food for a period of at least six hours. The anesthesia should be as short and as light as possible to satisfy the requirements of the operator. The dangers of chloroform should always be kept in mind, and if it is used extra care on the part of the anesthetist should be exercised. The operation should be as rapid as is consistent with care and thoroughness and should in every instance secure complete enucleation of the tonsil irrespective of the method employed. All hemorrhage should be positively checked before the patient is removed from the table. Attendance of a nurse for at least six hours following the operation is essential. Convalescence in bed should be enforced for a period of three to four days. This insures, a minimum loss in weight and a more rapid recovery. f x-Ray Treatment of Tonsils and Adenoids.—Considerable literature has accumulated relating to the treatment of diseased tonsils and adenoids by means of x-ray. Witherbee, Remer, and others have made careful and painstaking observations of a large series of cases. It would appear that they have established a field of usefulness for this procedure. In cases in which there is gland hyperplasia with infected foci the x-ray has given satisfactory results in sterilizing the infected areas and shrinking the glandular tissue. In cases with marked connective tissue increase enucleation by sur- gical procedures will always remain the operative treatment. For cases of diseased infected tonsils in subjects with status lymphaticus, the bleeding diathesis, and in grave cardiac disease it is wise to give x-ray therapy a trial at the hands of those skilled in its use. Benefits of the Removal of the Tonsils and Adenoids.—The usual advantages claimed, those relating to mouth breathing, facial deformities, etc., are sufficiently well known to require no mention. Certain other benefits are perhaps not generally appreciated. Effect Upon Delicate Children.—In office work one has occasion to treat a large number of children who come because of defective growth, who are suffering from secondary anemia, or who are otherwise delicate. Remarkable improvement in these children follows the removal of diseased tonsils and adenoids. Influence Upon Acute Infections.—In grippe, scarlet fever, measles, diphtheria, and other acute infections a considerable source of danger lies in the associated pyogenic infections of the throat and nasopharynx, involving secondarily the ears and the adjacent structures, the glands, and through the blood-stream the kidneys and the heart. The presence of diseased tonsils and adenoids supplies an ideal culture field for pyo- genic bacteria and greatly enhances the child’s chances for dangerous ACUTE RETROPHARYNGEAL ABSCESS 327 complications. For example, it is comparatively rare to find otitis media in the absence of adenoids. Adenitis in any common form is a relatively unusual occurrence in a child who has had the adenoids and tonsils properly removed. Notwithstanding the large number of cases operated upon, one never hears regret expressed by the parents because of an operation properly performed. RETROPHARYNGEAL ADENITIS Retropharyngeal adenitis, as the name implies, is an inflammation of one or more of the glands situated posterior to the pharynx, between the pharyngeal and prevertebral muscles. Symptoms.—Pain and difficulty in swallowing are alwrays present. Other symptoms are fever—100° to 103° F.—and loss of appetite. The patient often holds the head toward the affected side, so as to relax the muscle tension caused by the tumor. If the adenitis is situated low down, disturbance of the voice (cracked voice) and respiratory obstruc- tion may result. Diagnosis.—In an acute case inspection of the throat will usually show a swelling at the right of the median line. If situated low down on the posterior pharyngeal wall, the adenitis may escape detection. Upon digital examination, instead of a smooth, flat surface, the finger encounters an elevated, rounded mass, which should not be mistaken for an unduly prominent cervical vertebra. Prognosis.—The glands, as a rule, suppurate, forming a retropharyn- geal abscess. This, however, does not invariably follow. Treatment.—The treatment must be both local and constitutional. Local treatment consists in cleanliness. The mouth should be washed with a saturated solution of boric acid after each feeding. Iodids, in treating adenitis in children, have been found of questionable service. More is accomplished by suitable diet and plenty of fresh air. ACUTE RETROPHARYNGEAL ABSCESS Acute retropharyngeal abscess is the result of an infection of one or more of the retropharyngeal lymph-nodes which form a chain on either side of the median line, posterior to the pharynx, and between the pharyn- geal and the prevertebral muscles. Location.—The abscess is most frequently situated to the right of the median line. It may be located high in the pharynx, so as to be plainly visible when the mouth is well opened, or it may be placed low, posterior to the larynx and upper trachea. Usually the abscess points anteriorly into the throat. It may point both externally and internally. In a large number of cases not one was seen that pointed externally only. Age of Patients.—Retropharyngeal abscess is pre-eminently a disease of infancy. The retropharyngeal lymph-nodes are said to disappear at the third year. We have not seen a case in a child over three years of age. Etiology.—Any active infection of the throat may cause the dis- ease. It may occur without our knowledge of any infectious process having been present. All throats continually harbor pathogenic bacteria, 328 THE PRACTICE OF PEDIATRICS which may infect the retropharyngeal lymph-nodes. The disease is usually secondary to retropharyngeal adenitis due to infection from ad- jacent diseased structures. It has not been our observation that retropharyngeal abscess is a common sequel of diphtheria and the exanthemata. Symptoms.—Morse and others have emphasized the fact that these cases are usually overlooked—erroneously diagnosed. They are fre- quently diagnosed as cases of adenoids, and the removal operation is advised. It is a mistake to lay down too definite a symptomatology of a condi- tion that lends itself to widely varying symptoms. In describing the disease writers tell us that the patient holds the head in a characteristic position—backward and toward the affected side—that the breathing is noisy and stertorous in character, that there is difficulty in swallowing, that there are enlarged lymph-glands at the angle of the jaw, that there is usually a high fever, and that a bulging of one side of the posterior pharyngeal wall is usually visible. It is exceedingly rare to find this combination of symptoms. There are two diagnostic symptoms that are present in all cases—difficulty in swallowing and a persistently changed voice—a so-called cracked, high-pitched voice. These symptoms should lead one to suspect retropharyngeal adenitis or abscess, and the finger examination determines which condition is present. If adenitis exists, a rounded, hard tumor will be felt; if an abscess has formed, a soft, fluc- tuating tumor will be detected. This may be placed so high in the pharyn- geal vault as to be plainly seen through a wide-open mouth, or it may be low and out of sight in ordinary examination. There is a variation of at least 2 inches in the possible location of the abscess, and this fact accounts for the varying symptomatology. The difficulty in swallowing interferes greatly with nursing, and should always lead the physician not only to inspection but also to digital examination of the throat. Illustrative Cases.—Case 1.—A baby nine months of age had been under treatment in one of the outdoor clinics of New York City. A diagnosis of adenoids had been made and a day appointed for the operation. The mother, wishing to have the diag- nosis of adenoids confirmed, brought the child to the Babies’ Hospital. The symptoms of mouth-breathing, nasal voice, and slight difficulty in swallowing had been present for a couple of weeks. There was no characteristic position of the head, no rigidity of the neck, no superficial enlargement of the lymphatic glands. Inspection of the throat disclosed a bulging forward of the soft palate on the right side. A digital examination revealed a round, fluctuating mass, the size of a hickory-nut. It was found high on the posterior pharyngeal wall and almost entirely covered by the soft palate. No adenoids were present. Case 2.—A baby two years of age had been ill for a week with tonsillar diphtheria and was thought to be recovering, when suddenly the voice became hoarse and croupy, with gradually increasing dyspnea. Both expiratory and inspiratory obstruction were present, such as we expect in laryngeal diphtheria, and the attending physician, an excellent practitioner, naturally concluded that the diphtheric process had extended to the larynx. There was stiffness of the neck, but no nasal obstruction. (See above.) There was slight difficulty in swallowing. Inspection of the throat with a dim light revealed nothing but the enlarged tonsils. The writer was called to intubate, and finding the respiratory obstruction sufficient to require intubation, proceeded to make a digital examination, as is his custom before intubating. He was not a little sur- prised to find a soft, fluctuating mass low down in the pharyngeal wall, extending below and pressing against the glottis. The abscess was opened, with immediate relief of the obstruction. Case 3.—A baby, seven and a half months of age, was an inmate of the country branch of the New York Infant Asylum during the senior author’s service in that ACUTE RETROPHARYNGEAL ABSCESS 329 institution.1 His attention was first called to the child because of the difficulty in swallowing. There was very little obstruction, but the voice was harsh, hoarse, and croupy. About a month previous there had been a suppurating submaxillary adenitis. On examining the throat, a large abscess was visible on the right pharyngeal wall, extending downward as far as could be seen. This case afforded the author’s first experience with retropharyngeal abscess, and a Denhard gag of the O’Dwyer set, which should never be used in these cases, was introduced while the child was held in an upright position by the assistant. While the writer was feeling for the thinnest point of the sac for a suitable place for the incision, the child suddenly stopped breathing, and became limp and apparently lifeless. An intubation tube, the smallest of the O’Dwyer set, was quickly introduced without the gag. After several minutes of artificial respira- tion, the use of oxygen, and free hypodermic stimulation with brandy, respiration was again established. The first inspiration was so long delayed that we had almost given up the case as hopeless, when the first short gasp occurred. In half an hour the child had sufficiently recovered to allow the opening of the abscess. This was done without a gag, with the tube in position. After a copious discharge of pus the tube was removed and the child recovered. In. this case the suffocation was doubtless due to the introduction of the gag and the pressure of the finger, which forced the pus into the lower portion of the sac which extended below the glottis, where the pus exerted sufficient pressure to prevent the entrance of air. Case %.—A private patient one year old had diphtheria—laryngeal, faucial, and tonsillar. Under 9000 units of antitoxin and intubation satisfactory progress was made, and on the eighth day of the illness the tube was removed. It had to be replaced in a few minutes because of returning dyspnea. Upon replacing the tube an abscess was found in the right posterior pharyngeal wall, pressing upon and extending below the larynx. The presence of the tube had prevented the recognition of the abscess. Upon determination of the cause of the obstruction the abscess was evacuated, but the marked edema of the glottis still caused considerable respiratory obstruction, and the tube was required for two weeks longer. The child made a perfect recovery. Case 5.—Two weeks after the apparent termination of a fever of several days’ duration ascribed to otitis a sixteen-month-old girl developed persistent vomiting attacks associated with more fever. Vomiting occurred immediately after the taking of food, whether solid or liquid, was not projectile, and was unaccompanied by signs of digestive incompetency. The vomiting was promptly terminated by the discovery and incision of a retropharyngeal abscess. In this instance dyspnea, hoarseness, the peculiar attitude of the head and neck, and pronounced cervical adenitis were all lacking. The above cases are cited in detail in order that the reader may the more fully realize that retropharyngeal abscess may exist without the so- called “characteristic symptoms,” and also to emphasize the fact that many cases have been, and will continue to be, overlooked until physicians use the finger as an aid to diagnosis of the diseases of the upper respiratory tract. It is to be remembered that there is no “characteristic breathing” and no “characteristic position” of the head with retropharyngeal abscess. Fever.—There is no characteristic temperature: it may vary a degree or two from the normal or it may range high—from 103° to 105° F. Treatment.—There is but one means of treatment—incision and evacuation of the pus. In order that this may be done it is necessary that the child be under perfect control. The arms should be bound to the sides with a large towel, or a small sheet, securely pinned. The patient is held in an upright position on the lap of the attendant, who passes his left arm around the child, while his right hand grasps the forehead, draw- ing the head for further support backward against his right shoulder. The operation should be performed in a good light—either reflected light from a head-mirror or direct light from a window. With a tongue depressor in the operator’s left hand holding the tongue out of the way, the mouth is kept open, and the right hand is free to make the incision, 1 The case was reported at the time by Dr. Henry E. Tuley, assistant resident physician. 330 THE PRACTICE OF PEDIATRICS for which an ordinary scalpel is used. The proximal portion of the cutting surface should be guarded with adhesive plaster wrapped around the blade. The incision should be made from above downward, at least \ inch in length. A basin should be in readiness and the attendant should be instructed to invert the child at a word from the operator as soon as the incision is made. This allows the pus and blood, which, if aspirated into the trachea, may produce fatal results, to stream out of the mouth. While the abscess is discharging and the head is dependent, the clean index-finger of the operator should explore the cavity, enlarge the opening, if necessary, and remove any necrotic tissue that may be present. The case should be carefully watched for several days, as the opening may close before resolution is complete, particularly if it has not been enlarged with the finger. Recovery is usually complete in from five to seven days. Occasionally the abscess points outward and requires external incision. RETROPHARYNGEAL ABSCESS COMPLICATING TUBERCULOUS CARIES OF THE CERVICAL VERTEBRAE This is usually wrongly described as identical with idiopathic retro- pharyngeal abscess, but actually is a part of, and results from, tuberculous disease of the spine, which will be referred to later (page 795). ACUTE CATARRHAL LARYNGITIS (SPASMODIC CROUP) In acute catarrhal laryngitis two factors are operative: the local infection, causing a swelling and infiltration of the mucous membrane, and the laryngeal spasm which is apparently excited by the local process. Etiology.—The disease may be primary or secondary to inflamma- tory conditions in the nasopharynx. Exposure to cold is a predisposing cause. Rachitic children, if they develop the disease, are liable to have it in a severe form. They are no more predisposed, however, than normal children. Adenoids and enlarged tonsils are predisposing causes. Illustrative Case.—A case which demonstrates the possible effects of sudden cold occurred at the New York Infant Asylum. A delicate baby, six months of age, was exposed for a few minutes on a very cold, windy, December day, with no head covering and simple ward clothing. Within an hour a croupy cough had developed, and in three hours intubation was necessary. Pathology.—Early in the attack the mucous membrane is swollen and free from secretion. In older children when a larvngoscopic exam- ination is possible, the mucous membrane is seen to be intensely con- gested and dry. When resolution begins, the parts appear glistening and edematous. The lesion itself, however, is never sufficient to produce the obstruction to inspiration peculiar to these cases, as the mucosa is probably alone involved. Symptoms.—The onset may be sudden or gradual. Cases of gradual onset usually follow an acute inflammatory condition of the nasopharynx, the fauces and larynx becoming successively involved over a period of perhaps two or three days before the laryngitis is well marked. The temperature at the onset is usually not high. One of the early symptoms indicating laryngeal involvement is a hard, dry cough, croupy and “bark- ACUTE CATARRHAL LARYNGITIS (SPASMODIC CROUP) 331 ing” in character. The croupy cough increases in severity toward even- ing, and is often associated with urgent respiratory obstruction. In a typical case with sudden onset the following are the more fre- quent symptoms: The child retires at the usual hour in apparently good health; a few hours later he wakes with the characteristic cough, active laryngeal spasm, cyanosis and labored efforts at inspiration involving dilatation of the alse nasi, suprasternal and infrasternal recession, pro- fuse perspiration, and rapid pulse. The expression is anxious and The child cries in fear. The temperature is variable, but usually elevated. Expiration is usually unimpeded. Under right treatment the symptoms of spasm subside and do not recur on the following night. The cough, which persists for a few days, subsides under proper treatment. In some of the cases, however, the course is not so favorable; the cough continues, becoming stridulous, every inspiration being accompanied by a loud crowing sound, and in extreme instances the laryngeal obstruction due to the swelling and laryngeal spasm is so seVere as to require intuba- tion. In our experience, however, this is very rare. Only one child with catarrhal, non-membranous croup—the infant already referred to—re- quired intubation. Differential Diagnosis.—Acute laryngitis may be confused with diphtheric or membranous laryngitis. (For differentiation, see p. 697.) Laryngismus stridulus may be mistaken for catarrhal laryngitis. Differentiation is easy when one remembers that in laryngismus stridulus there is no cough, and that the laryngeal spasm is often associated with excitement or fright in conjunction with Furthermore, laryngismus stridulus does not occur as a definite acute illness, but as a reaction to an underlying constitutional defect. The continuous obstruc- tion, always associated with inflammatory conditions of acute catarrhal laryngitis, is, moreover, absent in laryngismus. Retropharyngeal adenitis or abscess may be confused with catarrhal laryngitis. Respiratory obstruction in acute laryngitis is apparent only during inspiration, and the cough and dyspnea are usually of sudden onset. Retropharyngeal adenitis and abscess are characterized by a persistence of the symptoms while the disease is active. Digital explora- tion of the pharynx makes the differentiation final. In congenital stridor the stridor is relieved by stress or excitement, the noisy breathing and other evidences of obstruction being worst when the child is quiet or asleep. Treatment.—In the treatment of catarrhal laryngitis in children two conditions must be kept in mind: first, the inflammatory infiltra- tion and dryness of the parts, producing the metallic cough and the stridulous breathing; second, the laryngeal spasm, which is purely a nervous manifestation, doubtless due to irritation of the terminal fila- ments of the recurrent laryngeal nerves. By no means every case of laryngitis in a child develops into croup. When croup is present, however, we know that its existence is due to the association of laryngeal spasm with congestion and inflammation. If we are to promote quick recoveries we must not lose sight of the im- portant nervous element. Expectorants.—For the simple coughs, without accompanying in- 332 THE PRACTICE OF PEDIATRICS terference with respiration, treatment with expectorants and steam is of great service, regardless of the age of the child. This treatment should be preceded by the administration of a full dose—from 1 to 3 teaspoonfuls—of castor oil. To a child under one year of age a tablet composed of tartar emetic, 1/100 grain, with powdered ipecac 1/60 grain, should be given every two hours—eight doses in the twenty-four hours. If the tablets or powders are not available, 2 drops of syrup of ipecac may be given instead. To a child from one to two years of age a tablet or powder composed of 1/100 grain of tartar emetic, 1/40 Fig. 61.—Crib prepared for steam inhalation. grain of powdered ipecac, and \ grain of Dover’s powder may be given at two-hour intervals—eight doses in twenty-four hours. After the first day the treatment should be resumed early in the morning, so that by evening, when the cough and spasm are most severe, the full influence of the drugs may be secured. From the third to the sixth year a powder or tablet composed of tartar emetic, 1/90 grain, powdered ipecac, 1/30 grain, and Dover’s powder, | grain, should be given at two-hour inter- vals—eight doses in twenty-four hours. At least eight doses of one of the above prescriptions should be given daily in order to get the full benefit ACUTE CATARRHAL LARYNGITIS (SPASMODIC CROUP) 333 of the drugs employed. If the Dover’s powder produces constipation, this ingredient may be omitted or counteracted by a laxative. Ordinarily treatment need not be continued more than two or three days. In case the attack is mild the Dover’s powder should be omitted. Cold Compresses.—In the treatment of older children the application of a cold compress to the throat is a valuable local measure. A napkin or piece of old linen so folded that there are at least six layers of the material, should be moistened with cold water at 60° F., wrung thor- oughly, and placed against the neck, under the jaw, so as to extend from ear to ear. Over this should be placed a piece of oiled silk or rubber tis- sue held in position by a strip of thin muslin or cheese-cloth, which should be brought together at the ends and fastened at the top of the head. The compress should be changed every thirty minutes. In the manage- ment of very young children this measure is rarely satisfactory, for the reason that it is difficult to force the child to allow the bandage to remain in place. The practice of placing the compress around the neck, as is often done, is of no value, as the dressing does not even overlie the affected parts. Steam inhalations are effective only when the patient is kept in an inclosed space. Steam diffused throughout the room is of little or no service. The most comfortable and practical place for the child is in his crib, which should be covered with a sheet. An open umbrella may be employed when a crib is not available. Under the umbrella, which rests upon the bed, lies the child, and covering all is a sheet pinned to the umbrella. If preferred, the open umbrella, draped as before, may be placed over the baby carriage. Any apparatus is ade- quate which will furnish steam and conduct it to the inclosed space. The Holt croup kettle when obtainable is always to be used. The steam- ing may be continued for hours. The sheet should be removed occasionally for a few moments in order to allow a change of air. Usually a child may be kept under the tent from twenty minutes to one-half hour with- out such a change. The tent is seldom so close as to prevent all ventila- tion. Calomel Fumigations.—A quicker and more effectual means than the treatment with steam is the use of calomel fumigations. The patient is placed under a tent prepared as above. Ten grains of calomel are placed in any tin receptacle, which rests or is held over the flame. The Ermold lamp, made especially for this purpose, is recommended, al- though the ordinary alcohol lamp used for warming milk answers every requirement. An ordinary kerosene lamp has served well in a few instances, the calomel being placed in the cover of a tin can which was held by a pair of pincers over the top of the lamp chimney. Regardless of the method the fumigation must be constantly watched by some competent person, so as to avoid the possibility of igniting the bedclothes. When the fumes begin to fill the tent, the child will cough considerably. If the cough continues for more than a few minutes, a portion of the vapor should be permitted to escape. The calomel will be consumed in from five to ten minutes, depending upon the degree of heat used. After the tent is filled with the vapor, the child may inhale it for about one-half hour. The vapor produces free secretion from the mucous membrane of the parts, 334 THE PRACTICE OF PEDIATRICS and local depletion, resulting in enlargement of the lumen of the larynx and consequent relief of the symptom. The fumigations may be re- peated after an interval of two or three hours. In a non-diphtheric case it is rarely necessary to repeat the inhalations more than two or three times. Antispcfemodics.—In the cases of sudden onset, in which the spas- modic element is prominent at the commencement of the attack, as indicated by the high-pitched, crowing inspiration, and in some extreme cases by the struggle for breath, the cyanosis, the stridor, and the infra- sternal recession, the above treatment will not avail. We must combine an emetic with antispasmodic drugs. A full dose of syrup of ipecac—1 to 2 teaspoonfuls—or sufficient to produce emesis—should be given at once. If vomiting does not result in twenty minutes, the ipecac should be repeated. After emesis has taken place, the antispasmodic remedies should be brought into use. Antipyrin and sodium bromid are especially effective at this stage. Antipyrin appears to have a direct sedative action on the nervous mechanism of the larynx. To a child two years of age the following prescription may be given: Antipyrini gr. j Sodii bromidi gr. ij Syrupi ipecacuanha} gtt. ii-iij Aqua} q. s. ad. 3j M.

Antipyrini gr. ij Sodii bromidi gr. iv Syrupi ipecacuanha gtt. iij Syrupi rhei gtt. xv A qua q. s. ad. 3j M. Sig.—One such dose every two hours—eight doses in twenty-four hours. TRAUMATIC LARYNGITIS Traumatic laryngitis, although a very rare condition in children, is occasionally observed. It may be caused by the inhalation of steam or irritating gases or the aspiration of carbolic or other strong acids. Illustrative Case.—Death resulted from the aspiration of pure carbolic acid by a child three years of age who was given a teaspoonful of the acid by a five-year-old sister. As soon as it passed the lips the patient cried and coughed. None of the acid was swallowed, apparently, but sufficient was aspirated into the larynx to produce intense congestion and sufficient edema to require immediate operative measures. The parts sloughed extensively and the child died in two weeks from pneumonia resulting: from sepsis. Treatment.—No case of corrosive injury to the mucous membrane, sufficient to produce congestion and edema with a resulting inspiratory obstruction which requires operative relief, should ever be intubated except as a temporary expedient, since the presence of a tube will in- variably cause extensive sloughing. If the case is urgent, tracheotomy is the only justifiable operation. In two cases due to irritating gases (sulphur dioxid in one case and steam inhalation in another) the treat- ment consisted in the use of cold applications to the neck by means of wet compresses at a temperature of 60° F. Both patients recovered. FOREIGN BODIES IN THE LARYNX 335 LARYNGEAL OBSTRUCTION Laryngeal obstruction may be either complete or partial, causing entire cessation of, or greatly impeded, respiration. As the calls upon the physician for aid in these cases are attended with great urgency, it is well to bear in mind the conditions which may give rise to, or di- rectly cause, laryngeal obstruction. These are referred to in detail under their respective headings. In order of frequency they occur as follows: 1. Acute Catarrhal Laryngitis (Catarrhal Croup), p. 330. 2. Laryngismus Stridulus, p. 537. 3. Membranous Laryngitis (Laryngeal Diphtheria), p. 696. 4. Retropharyngeal Abscess, p. 327. 5. Foreign Bodies in the Larynx (see below). 6. Traumatic Laryngitis, p. 334. 7. New Growths. Acute catarrhal laryngitis, membranous laryngitis, laryngismus stridulus, and retropharyngeal abscess are by far the most frequent causes of laryngeal obstruction in children. In children, edema is a very infrequent cause of laryngeal obstruction. When present, it is a complication or sequel of other pathologic states; for example, it may result from an inflammation accompanying a low-placed retropharyn- geal abscess, a traumatic laryngitis after the inhalation of irritating gases, or from the aspiration of corrosive fluids or powders. (See In- sufflation Pneumonia, page 381.) Illustrative Case.—A patient eighteen months of age, during convalescence from a mastoid operation, developed a cellulitis in the tissue about the wound. The inflam- mation involved the entire side of the face, the lips, and mucous membrane of the mouth, and eventually extended to the larynx, producing edema, with most urgent symptoms of laryngeal obstruction. The part played by the thymus gland in causing laryngismus is not at all clear; the subject is discussed on page 473. FOREIGN BODIES IN THE LARYNX Foreign bodies are usually lodged in the larynx by an act of sudden inspiration attended by a quick forward movement of the head, as in coughing or laughing with a foreign body in the mouth or between the teeth. The patient is immediately seized with a violent paroxysm of coughing and suffocation, the severity of which depends upon the size and shape of the foreign body. Treatment.—Inversion of the patient has repeatedly been of no service whatever. The first procedure is to introduce into the mouth the index- finger, with the hope that a portion of the mass may protrude sufficiently to make possible its removal. Should the attempt fail, a laryngeal forceps should be brought into use, its introduction being guided and guarded by the index-finger. When this is not successful tracheotomy should be performed to relieve the child from immediate danger of suffocation, after which further surgical procedures may be considered. 336 THE PRACTICE OF PEDIATRICS The Lungs EXAMINATION OF THE LUNGS Four methods are commonly employed in lung examination: (1) Inspection. (2) Palpation. (3) Percussion. (4) Auscultation. Inspection.—Inspection of infants and young children is of value in determining the existence and nature of any deformity, as well as the rapidity and character of the respiration. The frequency of respiration varies considerably in children. The younger the child, the more rapid the respiration. The variations in number of respirations per minute are about as follows: Under one year of age 30 to 40 One to three years of age 24 to 30 Three to ten years of age 20 to 24 The most common deformity is the rachitic chest, or so-called pigeon- breast. In association with the rachitic chest, as one of the results of the rachitis, is found the funnel chest, which is characterized by marked depression of the sternum. The Depressed or Contracted Chest.—This condition is a result of pneu- monia with pleuritic exudation and subsequent adhesions between the lung and the chest wall. Dilatation of the lung is interfered with; the balance between the intrathoracic and extrathoracic air-pressure is not maintained, and deformity is the outcome. Inspiration is marked by a lack of motion on the part of the diseased side as compared with the normal side. The Distended Chest.-—When there is effusion into the pleural cavity, and, rarely, when there is pneumothorax, one side of the chest may be much larger than the other. In thin subjects the marking of the ribs is much less pronounced than normal, the sunken interspace being ob- literated by the pressure from within. In the distended chest also there will be observed a marked absence of respiratory movement. A great many cases, however, of pleuritic effusion are seen in which such bulging is not present. Asthmatic or Fixed Chest.—Chests of this type are quite common in children, and are so characteristic that by watching the respiration one may readily make a correct diagnosis of the existing condition. In chil- dren normal breathing is of the costal type; that is, there is an outward movement of the ribs in inspiration and a downward and inward move- ment during expiration. In the emphysematous and those undergoing asthmatic seizures both sides of the chest become inactive and the res- piration is largely diaphragmatic. Defective Expansion.—In pneumonia and in pleurisy there is de- layed and incomplete expansion of the diseased side. In pneumonia, also, there is unusual rapidity of respiration; and in acute pleurisy, char- acteristic, guarded, interrupted inspiration. In atelectasis the inspira- tion is very feeble with little or no expansion. In empyema and pneu- mothorax there is little or no expansion over the affected area. Palpation in the lung examination of infants and young children is of little value. Fremitus serves only to corroborate what may be EXAMINATION OF THE LUNGS 337 learned by percussion and auscultation, and is not to be relied upon. The absence of fremitus in the case of a thin or average built child usu- ally means the presence of fluid in the pleural cavity, but, in the pres- ence of a thick layer of adipose tissue the sign is of little or no value. The presence of marked fremitus may mean consolidation of the lung. The absence of fremitus is no guarantee that there is no consolidation. Percussion.—The value of percussion depends upon the normal resonance of the chest when tapped with the finger or instrument. What is known as normal resonance ;s the sound produced by percussion over an air-filled lung. The usefulness of percussion in physical diagnosis depends upon the nature or quality of the note and the sense of resistance imparted by the chest to the percussed finger. When possible, percussion should be practised with the patient in a standing or sitting posture. The child should be quiet, if possible, as crying not only disturbs the listener, but changes the quality of the note as a result of the air taken into the chest and the tension on the chest muscles. Light percussion with the finger is preferred to that obtained by pleximeter. The chief value of percussion in pulmonary diagnosis is in determining the presence of fluid in the chest. The terms employed for expressing the findings in a given case are normal resonance, hyperresonance, dulness, tympanitic dulness, and flat- ness. The possibilities of variations in the resonance within the normal are considerable. The position of the patient, the age, the condition of the patient, whether thin or fat, whether quiet or crying, are all factors which may cause the percussion note to vary. The student should famil- iarize himself with the normal by percussing the chests of many normal children of different ages. Hyperresonance of tympanitic quality is obtained over a hollow body, as over the stomach, over a distended colon, or a pneumothorax. Dulness is characterized by short, high-pitched sounds, caused by a solid body or fluid within the chest cavity, which interferes with the production of the normal resonant note. Flatness is the extreme degree of dulness, and is best demonstrated by percussing a chest filled with fluid. An important feature in deter- mining dulness and flatness is the sense of resistance offered the percussed finger by the chest wall. In the presence of contained fluid the elas- ticity and vibration of the chest wall are greatly diminished, a fact read- ily appreciated by the finger percussed. Auscultation consists in examination of the lung by the ear placed directly against the chest, or assisted indirectly by a stethoscope. Use of the stethoscope in examining infants and young children is almost a necessity. On account of the smallness of the chest and the comparatively large area covered by the ear during direct auscultation a larger field of sound conduction is covered than is desirable for pur- poses of accurate diagnosis. The small stethoscope bell is best, for the reason that when applied to the chests of emaciated infants it will fit the surface better than a large bell. If the bell does not accurately fit the chest extraneous sounds render examination impossible. For accurate work with infants the unaided ear—so-called immediate auscultation—is out of the question. With older children, after the third or fourth year, 338 THE PRACTICE OF PEDIATRICS the ear alone may be employed if the physician is unable to accustom himself to a stethoscope. The physician must accustom himself to correct auscultation with the child crying. This, of course, means forced breath- ing and a great deal of extraneous noise. To one who is accustomed to lung examination of young infants it matters little whether or not the child cries; in fact, in many instances crying is of distinct advantage, because it brings out the respiratory quality of all portions of the lung. In the examination of older children forced breathing is necessary to trans- mit the sounds we require for diagnosis. In auscultation all the diagnostician’s attention is required for the work in hand. Concentration of the mind is most necessary. Students are best taught to close their eyes during auscultation for the purpose of excluding all visual objects. All sounds appear louder in the darkness or when the eyes are closed. The position of the examiner is important. He should sit erect or lean slightly forward, but never incline his body more than 45 degrees. When the examiner leans too far, the circulatory changes in his ears make his work unsatisfactory and uncertain. It is essential for the student to familiarize himself with the sound produced in the lung and transmitted to the chest wall in the act of normal and forced breathing. The sounds thus produced are known as those of vesicular breathing. Fig. 62.—Vesicular breath- ing. Fig. 63.—Distant vesicular breathing. Fig. 64.—Exaggerated ves- icular breathing. Vesicular breathing has a range of variations within the normal. As in the matter of the study of percussion sounds, repeated examinations of the chest of normal children of various ages and conditions are ab- solutely required before the nature of normal breathing and its possible variations will be appreciated. Various terms have been used in a com- parative sense to describe vesicular breathing, such as “rustling,” “blow- ing,” “swishing,” “purring,” etc.; these are all misleading and useless because there is no other sound resembling the sound of vesicular breath- ing which deserves mention in comparison. Different investigators have attempted, by means of various devices, to produce the sounds resembling the respiratory murmur in health and its changes in disease, without success. The respiratory cycle includes the taking of air into the chest—in- spiration; and the forcing of the air out of the chest—expiration. The duration of inspiration in comparison to expiration is in the ratio of five to three. The inspiratory sound is not only longer, but harsher in quality than that of expiration. The respiratory characteristics have been dia- grammatically described by Cabot in his excellent work on physical diagnosis. Cabot’s diagrams are here used, but modified to correspond to the respiratory peculiarities of children. EXAMINATION OF THE LUNGS 339 Inspiration is represented by the upward stroke and expiration by the downward stroke. The length of the upstroke, as compared with that of the downstroke, corresponds to the length of inspiration as com- pared with that of expiration. The thickness of the upstroke as com- pared with that of the downstroke represents the intensity of inspira- tion as compared with that of expiration. The pitch of inspiration as compared with that of expiration is represented by the sharpness of the angle which the upstroke makes with the perpendicular. In the foregoing, an attempt has been made to describe the various phases of normal respiration. That the two sides of the chest may show considerable variation within the normal, due to changes in the posi- tion of the body, the age of the patient, and whether he is at rest or active, as in crying, must be appreciated and learned only by repeated studies of the normal. Only when the student has so practised upon and studied the normal chest is he ready to take up the study of the signs of disease. Exaggerated breathing occurs when a sound lung or portion of a sound lung is called upon to do an extra amount of work. This type of breath- ing is simply compensatory, and occurs when a considerable portion of lung structure is incapacitated by consolidation, as in pneumonia, or by pressure, as in the event of effusion into the pleural sac. Fig. 65.—Bronchial breath- ing of moderate intensity. Fig. 66.—Distant bronchial breathing. Fig. 67.—Very loud bron- chial breathing. Diminished or weakened breathing exists when both inspiration and expiration are feebler than the normal. Diminished breathing may be due to fluid in the pleural cavity, to pleuritic plastic exudation covering the lung like a blanket, to partial infiltration of the air-cells, to pneumothorax, to bronchitis because the air is impeded in its passage to the air-cells, and to acute pleurisy which gives rise to much pain and causes a much shorter excursion of the chest walls than normal. In all these conditions inspiration is less deep than normal, and diminished respiratory sounds are the result. In laryngeal spasm and in diphtheric laryngitis the respiratory murmur may like- wise be greatly weakened because of the failure of sufficient air to pass the obstruction. Bronchial breathing has been symbolically represented and described by Cabot as follows: The increased length of the downstroke corresponds to the increased duration of expiration, the greater thickness of both lines corresponds to the greater intensity of both sounds, expiratory and inspiratory, while the sharp pitch of the gable on both sides of the perpendicular corresponds to the high pitch of both sounds. Expiration, it will be noticed, slightly exceeds inspiration, both in intensity and in pitch, but considerably 340 THE PRACTICE OF PEDIATRICS exceeds it in duration. As compared with those of vesicular breathing, almost all the relations are reversed. Bronchial breathing is found in conditions in which there is com- plete infiltration of the pulmonary air-cells, leaving only the bronchi open to the inspired air. The vesicular element in the breathing is, therefore, wanting, and the sound produced by the passage of air through the tubes is alone conveyed to the ear; and the more readily because of the solidity which the consolidated lung presents. Any condition, by causing con- solidation of the lung, obliterating the air-spaces, may produce bronchial breathing. Thus bronchial breathing of the most pronounced type may be found over a pleural sac filled with fluid. The lungs solidified by the pneumonia or compressed by fluid (carnified) give rise to bronchial breathing which is readily transmitted by the fluid under compression to the exterior of the chest wall. Bronchial breathing heard all over the chest (front, back, axilla, and apex) almost without exception means that the pleural cavity is filled with fluid. Failure to recognize fluid under marked signs of general bronchial breathing is one of the most fre- quent errors made in chest diagnosis in children. Bronchovesicular Breathing.—We do not recognize bronchovesicular breathing as a distinct type, but one of the forms of weakened or defect- ive breathing. Fig. 68.—Emphysematous breathing. Fig. 69.—Asthmatic breathing: s, s, s, Squeaking (musical) rales. In emphysematous breathing the inspiration is short and somewhat feeble, but not otherwise remarkable. The expiration is long, feeble, and low pitched. Asthmatic breathing differs from emphysematous breathing, the latter being characterized by greater intensity of inspiration. In asthmatic breathing, however, both sounds are usually obscured to a great extent by the presence of piping and squeaking rales. Cavernous Breathing.—Cavernous or amphoric breathing will be found over a cavity in the lung tissue or a large bronchiectasis. The respiratory sound has a peculiar hollow quality both upon inspiration and upon expiration. A low note is produced which has been com- pared to the sound produced by blowing gently into a wide-mouthed bottle. Rales.—Upon auscultation of the lungs rales of different kinds will be heard. A rale is the sound produced by impeded air in its passage through a bronchus to the lung. This may be brought about through a spasm of the tube, through thickening of its mucous membrane, or the presence of pus, mucus, or water in the bronchial tube. Rales of various types will be produced, depending upon the nature of the lesion BRONCHITIS 341 and the size of the tube affected. Thus when there is congestion with infiltration there will be sonorous rales in the large tubes and sibilant rales in the smaller tubes. Sonorous rales are low-pitched snoring sounds, roughened and grat- ing in character. Stridor in laryngitis is akin to the sonorous rales. Sibilant rales are squeaking, hissing, and crackling in character. In the smaller tubes they indicate the same condition as is productive of the sonorous rales in the large tubes, with this difference, that the advent of bronchial spasm is a considerable factor in the production of sibilant rales. Sibilant rales are almost always present in asthma and in asth- matic bronchitis, and may indicate an early stage of bronchitis. Mucous or moist rales are large, medium, and small; and vary in size and number, depending upon the nature of the lesion. They are produced by the passage of air through diseased bronchi containing exu- date, and are present in all catarrhal conditions of the lung from what- ever cause. In bronchitis and bronchopneumonia, if the examiner is suf- ficiently industrious, every variety of rale may at some time be heard. Crepitant and subcrepitant rales belong to the subvarieties of moist rales. BRONCHITIS Acute bronchitis, an inflammation of the bronchial mucous membrane, occurs with great frequency in infants and young children. Etiology.—The majority of cases occur during the colder months of the year, when houses are overheated, and when sudden changes in the weather are frequent. The sudden advent of exposure lowers the child’s resistance, and the infecting agents which are always present are then given a favorable field for activity. Predisposing Causes.—The chief predisposing cause is absence of resistance to bacterial invasion—a condition peculiar to child life. Infants and children who are rachitic or who suffer from other forms of malnutrition are particularly susceptible. Chronic rhinitis, enlarged tonsils, and adenoids are predisposing factors of no small consequence. Bacteriology.—The usual bacteriologic agents are the pneumococcus, the influenza bacillus, the staphylococcus, and various types of the strep- tococcus. Types.—Bronchitis may be divided clinically into three types: pri- mary and secondary acute forms and chronic bronchits. Primary.—In simple primary bronchitis there may have been an ex- posure to cold or wet, although this is not at all necessary. The disease is more apt to follow exposure to another individual who has a so-called “cold,” and who is, temporarily, at least, a germ carrier. Secondary.—This type is most often found associated with measles, whooping-cough, and grip, or following an acute catarrhal infection of the upper respiratory tract. Secondary bronchtis differs from the acute primary form only in the mode of onset. In the secondary type the onset is gradual—three or more days usually being required before the disease is well advanced. Chronic.—Chronic bronchitis is somewhat rare in the young. It occurs most frequently in conjunction with asthma, or in slow conva- 342 THE PRACTICE OF PEDIATRICS lescence after bronchopneumonia, and is an accompanying process in chronic pulmonary tuberculosis. Peribronchial thickening occurs in pro- longed cases. Pathology.—In simple bronchitis the lesion is very slight. The mucous membrane may show congestion and slight round-cell infiltration, and there may be elevation or loss of superficial epithelium in small areas where the infection is most severe. Symptoms.—The onset of acute bronchitis is usually sudden. The cough, which may be extremely troublesome, interferes with sleep, and, in the case of young infants renders the nursing and bottle feeding diffi- cult. The respirations are rarely accelerated above 30 per minute unless there is an associated bronchial spasm. (See p. 347.) There may be moderate prostration; in mild cases there is none. In severe cases the appetite is interfered with. The child is rather peevish and shows general discomfort. The usual range of the temperature in uncomplicated bronchitis is from 100° to 102° F. When the temperature remains above 102° F., or makes frequent excursions above this point, a complication of some kind will almost always be discoverable to account for the high fever. Frequent causes are intestinal disorder, a developing otitis, or a beginning bronchopneumonia. If the temperature ranges above 102° F. and the respiration is 40 or more, we may be almost certain of a developing pneu- monia. In chronic bronchitis the physical signs consist of various types of mucous rales in the bronchi. The medium-sized bronchi are, as a rule, the chief seat of this catarrhal process. Cough is the most active symptom, and is worse at night. Fever, if present, is due to the associated disease, as chronic bronchitis in a child is rarely an independent illness. Physical Signs.—Auscultation of the chest early in an attack will reveal a harsh, roughened respiratory murmur, fairly evenly distributed all over the lungs. Sonorous, sibilant, and mucous rales become audible in from twelve to thirty-six hours. Percussion.—There is no change in the percussion note except in the cases of asthmatic bronchitis (p. 347), which are characterized by hyperresonance or tympanitic dulness. Palpation is here of no aid. Duration.—The duration of an attack of bronchitis depends to some extent upon the child’s recuperative powers, but to a much greater degree upon the method of treatment. A primary case properly managed should terminate favorably in a few days. Many cases are not treated at all by a physician. It is these cases of neglected bronchitis which furnish a great majority of our cases of bronchopneumonia, a disease which contributes largely to the mortality of children under five years of age. Diagnosis.—Catarrh of the bronchial tubes, manifested by many rales of different types, is the chief diagnostic feature of simple bronchitis. Cases very often reported as those of capillary bronchitis, in which there is rapid breathing—40 to 60 a minute—high temperature—103° to 105° F. —and marked prostration, show at autopsy the pneumonic elements 343 BRONCHITIS which gave during life no other signs in the chest than a diminished respiratory murmur and many fine mucous rales. Differential Diagnosis.—Chronic bronchitis may be differentiated from pulmonary tuberculosis by the temperature range, elevation of the temperature being unusual in chronic bronchitis. The examination of the sputum, the tuberculin skin test, and the x-ray are essential aids to a sure diagnosis. Treatment.—The management of the primary and secondary cases is, in the main, the same, varying, of course, to meet individual condi- tions or symptoms. Before indicating what should be done in a case of bronchitis it may be as important, by way of emphasis, to advise what not to do. Do not seal the room up tight by keeping all the windows closed. Do not use an oil-silk jacket lined with wadding or any other material. Do not allow the child to be wrapped in blankets and shawls and held against a warm adult body. Do not give the child large doses of so-called “ex- pectorants” in a teaspoonful of a heavy syrup. The temperature of the room should be kept as near 68° F. as possible. There should always be direct communication with the open air. A window lowered an inch or two from the top, or the window-board described on p. 26, is a safe means of assisting in ventilation. The child should be kept in his crib and wear the night clothing to which he was accustomed in health. Many children with bronchitis do not feel particularly ill and rebel against the enforced inactivity. A patient who cannot be kept under the covers may wear a pinning-blanket or a bath-robe while sitting up in bed, but should not be allowed to sleep thus clad. The Diet.—If there is little or no fever the diet need be reduced but little. If there is fever, 100° to 101.5° F., with restlessness and ir- ritability, the food should be reduced in strength, the same amount of fluid being allowed as in health. The diet of a nursing baby can best be reduced by giving a drink of water before each nursing, and shortening the time allowed for nursing from one-third to one-half. We will thus avoid digestive disturbances, which often act as a very serious complica- tion of the existing disorder. Older children, receiving a mixed diet, may be given toast, cocoa, milk, broths, gruels, and fruit juices. Steam Inhalations.—Properly administered medicated steam inhala- tions are of greater service in bronchitis, particularly in treating young infants, than any other form of treatment which we possess. The steam- ing is best administered with the child placed in the crib, which is covered and draped with sheets. A croup kettle with alcohol lamp attachment is the most convenient means for generating steam. The nozzle of the croup kettle, which rests on a chair or stand, is carried under the tent at a safe distance from the child’s hands and face. For inhalation, creosote has given better results than has any other drug. Ten drops are added to one quart of boiling water and the steaming is continued for thirty minutes. Ordinarily, in an urgent case, steaming for thirty minutes is given at two-and-a-half-hour intervals day and night until the child recovers. Older children, and those whose condition is not grave, need not receive the steam after the bedtime of mother or nurse. It is well to allow a change 344 THE PRACTICE OF PEDIATRICS of air in the inclosed space at least three times during the steaming. This is done by raising the sheet for a moment or two and then replac- ing it. The side of the crib, if preferred, need not be draped. Counterirritation of the skin over the thorax is another very useful method of treatment in bronchitis. Full instructions must be given the mother and nurse as to how the counterirritant is to be applied, or the application will be very indifferently made. In most cases the mustard plaster has been the most convenient means of counterirritation, and has given the best results. It is well to begin with a strength of 1 part of mustard and 2 parts of flour. Two or three applications of this strength may be made. Later, when the skin becomes sensitive, the plaster is to be made weaker by the addition of more flour, 1 part of mustard to 5 or 6 of flour. In order to be effective the plaster should remain in contact with the skin from five to fifteen minutes, until a diffuse blush appears. The plaster is prepared as follows: Mix the mustard and the flour, using lukewarm water until a paste of medium thickness is formed. This is to be spread on cheese-cloth, old linen, or thin white muslin to a thickness of about | inch. Over this one thickness of cheese-cloth should be placed. The size of the plaster depends upon the age of the child and the area of lung involved. In a case of general bronchitis the entire thorax, front and back, should be covered. It is easier to make two plasters which meet under the arms than to make one to encircle the thorax, as is some- times done. A circle is cut out for the arms at the upper corners. If the plasters are sufficiently large to meet at the side, as mentioned above, they may be pinned together. When all is completed, the application really amounts to a mustard jacket. The plaster may be applied from two to four times daily, depending upon the urgency of the case. Counterirritation thus made is of great service early in the attack— during the stage of acute congestion. We question whether plasters are of much use after two or three days have elapsed. After removal of the plaster an application of vaselin is grateful to the patient. Mustard Baths.—A mustard bath, | ounce of mustard to 6 gallons of water, at a temperature of 110° F., is of considerable service in the very acute cases in young children, with extensive involvement of the fine tubes, usually known as “capillary bronchitis,” in which there is a great deal of bronchial spasm and considerable shock. The hands and feet are often cold, the respiration is rapid, and the child is considerably prostrated. Under such conditions the bath may be repeated with ad- vantage at intervals of from six to eight hours. The child is to remain in the bath from one to three minutes, during which time the trunk and extremities should be briskly rubbed with the bare hand. Drugs.—The value of drugs in the management of this disease has been considerably overestimated, and they are mentioned last because they are the least important of the remedial agents available. During the first stage of bronchitis, that of engorgement, indicated by a short, dry cough, and rough, sonorous breathing, small doses of castor oil and syrup of ipecac constitute perhaps our best medication. From the first to the third year 2 to 3 drops of castor oil and 2 to BRONCHITIS 345 3 drops of syrup of ipecac may be given every two hours; after the third year, 3 drops of syrup of ipecac and 5 drops of castor oil every two hours. At least eight doses should be given in twenty-four hours. Ordinarily, after twenty-four hours, auscultation will detect more secretion in the bronchi, the fever will diminish, and the child’s cough will become loose and less severe. The benefits from the oil and ipecac will be obtained in from forty-two to seventy-two hours, after which this medication should be discontinued. If the cough and the chest sounds tell us that the bronchi are not yet clear, a combination of tartar emetic, powdered ipecac, and am- monium chlorid may be used. To a child under six months of age a powder or tablet containing 1/150 grain of tartar emetic, 1/80 grain of powdered ipecac, and \ grain of ammonium chlorid should be given at two-hour intervals, eight doses in twenty-four hours; from six months to one year, tartar emetic, 1/100 grain; powdered ipecac, 1/60 grain; ammonium chlorid, \ grain, at two-hour intervals, eight doses in twenty- four hours. If the cough is very annoying and severe, requiring a seda- tive, l grain of Dover’s powder may be added to each dose for infants under six months, and \ grain for children over six months of age. From one to three years of age, tartar emetic, 1/100 grain; powdered ipecac, 1/40 grain; ammonium chlorid, | grain, may be given at two-hour inter- vals, eight doses in twenty-four hours, | grain of Dover’s powder to be added to each dose if the character of the cough demands a sedative. The tablet or powder, whichever is employed, should be given in 2 teaspoonfuls of thin gruel or plain water. After the third year 1/80 grain of tartar emetic, 1/20 grain of pulverized ipecac, and 1 grain of ammonium chlorid may be given every two hours, eight doses in the twenty-four hours. The use of tablets or powders should be insisted upon, particularly in treating very young children. The large doses of ammo- nium salts and ipecac in heavy syrups are to be avoided because of their liability to produce stomach disturbance. The treatment of secondary bronchitis depends to a certain extent upon the disease with which it is associated, and the procedure should be modified accordingly. Counterirritation and medicated steam in- halations ordinarily can be used, as they interfere but little with other necessary treatment. Treatment of Chronic Cases.—In chronic bronchitis the removal of enlarged tonsils and adenoids, fresh air, and change to a dry climate, if possible, are our best means of treatment. In addition, general sup- portive treatment is to be advised as in the management of subnormal children (p. 140). Creasote in small doses, 1 to 3 minims after meals, for a child from two to five years of age, has seemed to be of service to some of these children. The greatest success, however, with these cases has been achieved by ignoring the bronchitis temporarily and putting the child in the best hygienic surroundings. Outdoor life inland and a nutritious diet are far better than drugs. In many of these cases, under such a regime, the disease for which the child was brought for treatment has entirely disappeared without any specific medication whatever, show- ing that the bronchial catarrh was nothing more nor less than a manifes- tation of greatly reduced vitality. 346 THE PRACTICE OF PEDIATRICS RECURRENT BRONCHITIS Recurrent bronchitis without the association of asthma and without fever or prostration is occasionally encountered. A typical case of this kind is the following: Illustrative Case.—A. plump, well-nourished, four-year-old girl had a history of attacks of bronchitis lasting from five to seven days at intervals of not longer than three weeks. The physical examination was negative. The attacks commenced when she was two years of age and had continued for two years. The temperature was never over 100° F. with the attacks, and the child was not physically ill. She had never had cyclic vomiting, tonsillitis, or rheumatism. (The father was a sufferer from chronic rheumatism.) The patient was given a diet suitable for her age (p. 135), meat being allowed every second day. The considerable quantity of sugar which she had been taking was greatly reduced, only enough being allowed to make the food palatable. She was also given the following prescription: 1$. Sodii salicylatis gr. xxxvj Sodii bicarbonatis gr. lxxij Elix. simplicis 5v Aqua) q. s. ad. gij M. Sig.—One teaspoonful twice daily after meals. The above prescription was given for five days, followed by an interval of five days without medicine. This procedure was continued for five months, during which time there was no bronchitis. Later this medication was given ten days each month for one year, with entire relief of the trouble. Withholding sugar and fat from the diet was continued indefinitely. The patient has had no further inconvenience. When a child develops joint or bone disease, the family can usually recall an injury or fall of some sort to account for the trouble. So, also, in the event of bronchitis, an exposure, a change of clothing, or a change in the weather will usually be regarded as a cause of the attack. In the case above cited and in many others such factors evidently have had very little, if anything, to do with the bronchitis, for under the same climatic conditions the attacks cease when attention is given to the constitutional condition, and proper diet and medication are prescribed. The patients are usually of gouty or rheumatic ancestry. Treatment.—Sugar and fat cannot be tolerated by patients of this type. They should lead an active outdoor life when climatic conditions allow. There should always be communication between the sleeping room and the outer air. All possible influencing factors, such as en- larged tonsils and adenoids, are to be removed. (This operation, how- ever, is never sufficient in itself to prevent recurrences.) Diet.—Red meats, including beef, mutton, and lamb, should be given only every second or third day. Sugar is permissible only in sufficient amount to make the food palatable. If the case resists treatment, sugar is to be discontinued and saccharin substituted. Skimmed milk may be given as a drink, 8 ounces being allowed both for breakfast and for supper. Green vegetables and cereals well cooked and suitable for the age may be given freely. There must be a free evacuation of the bowels daily. If there is a tendency to constipation the management suggested on page 273 is to be applied. As in a certain group of asthma cases protein sensitization, particularly ACUTE SPASMODIC BRONCHITIS; BRONCHIAL AS1HMA 347 to egg, must receive consideration. Occasionally brilliant results follow the elimination from the diet of supposedly harmless food found bjr cuta- neous test to be toxic to the patient. The application of the protein theory has, however, been rather disappointing. Medication.—These patients are not influenced by the usual treat- ment for bronchitis, so that expectorant drugs may be omitted. Large doses of bicarbonate of soda do more toward shortening the attacks than does any other form of medication. To a child five years of age 10 grains should be given at two-hour intervals. The interval treatment, with diet, must be relied upon to prevent a recurrence of the attacks. Salicylate of soda is given for five days, in doses of from 3 to 5 grains, well diluted, after meals. The salicylate is then discontinued and the bicarbonate is given for ten days in the same dosage. Next the salicylate is resumed. In this way, by alternating the two drugs or by giving aspirin when the salicylate disagrees, the treat- ment is continued for two or three months. As the case improves an interval of rest from all medication is instituted. If it is more convenient the salicylate and the bicarbonate of soda may be given at the same time. Bathing.—The skin in these cases should be kept active, and once daily the child should be given a tub-bath in lukewarm water. After the bath a cool spray or spinal douche is to be used, the temperature of the water ranging from 50° to 70° F. An excessive degree of cold is not advisable; it should be sufficient, however, to insure a good reaction after brisk rubbing with a rough towel. ACUTE SPASMODIC BRONCHITIS; BRONCHIAL ASTHMA Infants and young children may suffer from spasmodic attacks of dyspnea—the manifestation of the disease in the adult. With asthma in the child, regardless of age, there is almost invariably an association of bronchitis. In some the nervous phenomenon of spasm predomi- nates with little bronchial involvement. In others there is consider- able bronchitis, with slight, moderate, or intense spasm. In the case of the infant and very young child the term capillary bronchitis has been given to two distinct conditions. In one there is an acute spasmodic bronchitis, and in the other an acute infection of the lungs (pneumonia) without localization. In acute asthmatic bronchitis the mode of onset, the lesions, and the fever are all as found in acute simple bronchitis. The bronchial spasm, however, differentiates the two forms from two standpoints: First, the respiration in the asthmatic type appears very rapid. A rate of 60 is not unusual. The excursions of the chest muscles are, however, incomplete and the rate in many instances is less rapid than it appears. Second, the chest signs are most dissimilar. In the spasmodic cases there may be an entire absence of, or very feeble, respiratory murmur, with inspiration short and squeaking in character, while the expiration is prolonged and accompanied by fine sibilant rales. These signs may exceptionally be localized in one lung or a portion of a lung, more often at the end of the attack, but, as a rule, occur equally in both lungs, the same auscultatory signs occurring over the entire chest. There is but little action of the respiratory muscles, the chest appears 348 THE PRACTICE OF PEDIATRICS held in fixed position of deep inspiration with little movement of the chest wall, the diaphragm being held contracted and undergoing only short ex- cursions. Both the entrance and exit of air are impeded, but the expira- tory act appears the more difficult. Cyanosis, profuse perspiration, and marked prostration are apparent if the attack is prolonged. Percussion elicits hyperresonance or tympanitic dulness. This type of bronchitis may occur in the youngest infant. Many older children always have the spasmodic condition with bronchitis. Etiology.—Among the many agencies that have been credited with the capacity for causing asthma, but one has been proved positively operative-—sensitization to foreign protein. This sensitization may be present at any age. The asthmatic reaction may be due to sensitization to foods or to inhalation of protein-bearing substances from plants and animals. In- fants with eczema frequently have an asthmatic type of bronchitis, and eczema in many infants is due to food anaphylaxis, most frequently to egg, and occasionally to milk. The list of such foods includes also a large variety of vegetables and cereals. Clinically we may divide asthma into two classes, the sensitive type and the non-sensitive type, according to the following tabulation made by Bell and Larsen.1 SENSITIVE TYPE NON-SENSITIVE TYPE Periodic attacks with complete or nearly complete cessation of pathologic signs between the attacks. 1. Course of the Disease Either chronic cough without dysp- nea or periodic remissions with mod- erate dyspnea, but the pathologic signs tended to remain constant between the remissions. 2. Type of the Attack Onset in which dyspnea was the most prominent symptom. This was usually characterized by slow, labored breathing with prolongation of the expiratory phase up to the beginning of the inspiratory Ehase, so that there was no period of rest etween. Cough was not prominent at first, but later, after the dyspnea had begun to subside, it became more prominent and lasted after the dyspnea had entirely dis- appeared. On auscultation in the early stages the rales were similar in all parts of the chest and occurred about equally dur- ing all parts of both inspiration and ex- piration. Toward the end they became looser and were patchy in their distribu- tion, resembling those of simple bronchitis. There was usually acceleration of the pulse- rate, but no rise in temperature. In those with periodic remissions cough at the onset was the most prom- inent symptom. Dyspnea, if it appeared, came on from twenty-four to forty-eight hours later and was not as severe as in the sensitive type. It also had a tendency to be more inspiratory in type. On auscul- tation during the attack the rales were often very similar to those found in the sensitive type, and later also showed a loose quality, but between the attacks these showed a tendency to remain con- stant, though fewer in number. There was nearly always acceleration of the pulse-rate accompanied by a rise in tem- perature. 3. Duration op the Attack This varied from a few minutes to a This varied from a few days to a few days and was followed by a relatively week or more and convalescence was rapid convalescence. relatively slower. 1 Classification and Management of Asthma in Childhood, Amer.

Behavior Toward Epinephrin Intramuscular injections of a solution of epinephrin chlorid 1:1000 gave marked immediate temporary relief. The relief obtained was not as marked. In the group of cases classified as non-sensitive are perhaps many in which the activating protein has not been discovered. Some children cough, wheeze, and have restricted asthmatic breathing with every attack of bronchitis; and yet we find that if we prevent them from contracting bronchial infections the asthma does not occur. It is possible, but not established, that in such cases the infecting bacterial organism causing the bronchitis is operative through its protein in causing asthma. In a group of 44 cases in which sensitivity was determined Bell and Larsen found the reacting proteins gave tests as follows: Rabbit hair, 32 positive reactions; horse dander, 8; cat hair, 6; dog hair, 1; guinea-pig, 1; feathers, 1; foods, 8; pollens, 3; total, 60 positive reactions. The importance of rabbit hair in causing asthma was first emphasized by Ratner.1 This hair is commonly used in the manufacture of felt and may be found in the hats of susceptible children. In many asthmatic infants and children there is an undoubted gouty (lithemic) diathesis. Not only are such children subject to bronchitis of the spasmodic type, but they also may have attacks of croup, eczema, cyclic vomiting, periodic fever, and periodic intestinal crises, with or without fever, and with or without gastric crises. Most important dietetic factors in these cases are fat and sugar, par- ticularly cow’s milk fat and cane-sugar. These patients during the asthmatic attack develop the acetone breath, but not to the degree that is noted in cyclic vomiting. Illustrative Cases.—Case 1.-—A girl eight years of age had the history of an attack of asthmatic bronchitis every month for several years. The asthma, although not severe, was present at the onset of the attack, and lasted for perhaps twenty-four hours. The bronchitis usually cleared up in about five days. She had spent but little time in New York because of her so-called frequent “colds,” and was brought by her mother for examination in contemplation of a change of residence. In Florida and lower California, where the patient had passed the winter, the attacks had occurred, but were mild in character. As soon as she returned home the attacks returned, keeping her from school for one week out of every four or five. When the matter of adenoids and tonsils was mentioned the mother hastened to state that the adenoids and tonsils had been removed twice, thus demonstrating that they were not a factor in the case. The family history disclosed that all the child’s antecedents on both sides, for three generations, had suffered either from rheumatism or gout. The mother had been a life-long sufferer from rheumatism. The child had never suffered from rheumatism or cyclic vomiting. Aside from revealing a mild secondary anemia and slight emphysema, the physical examination proved negative. Upon close questioning, it was found that the patient’s diet consisted of red meat twice daily; she disliked vegetables, took cereals only when covered with sugar, and drank milk only when 2 teaspoonfuls of sugar were added to each glass. She had candy and cake ad libitum. She was recovering from an attack of bronchitis when examined, and was taking an expectorant cough-syrup. 1 Ratner, B., Rabbit Hair Asthma in Children, Medical Clinics N. America, o, 1129, January, 1922. 350 THE PRACTICE OF PEDIATRICS This was discontinued, red meat was permitted but twice a week, the sugar was largely reduced, saccharin being used in the milk to satisfy the abnormal craving for sweets. She was bribed by the mother to eat green vegetables and cereals. The desserts con- sisted largely of stewed fruits flavored with saccharin. Candy, cake, and pastry were forbidden. Four grains of the salicylate of soda given three times daily for five days was followed by 10 grains of the bicarbonate three times daily for five days; then for five clays there was no medication. This treatment was continued for six months. During the following six months the salicylate and the bicarbonate of soda were given but five days each out of each month. During the entire year but one mild attack of bronchial asthma occurred. Case 2.—A most striking case of periodic asthmatic bronchitis occurred in a boy nine years of age. The father had had inflammatory rheumatism. Of the mother’s family, the grandmother was an invalid with rheumatism and the grandfather was slightly rheumatic. The boy was pale, but well nourished, weighing 68 pounds. He was very active mentally. He had had chickenpox and one attack of tonsillitis. The blood examina- tion showed 78 per cent, of hemoglobin, 5,500,000 red cells, and 8000 leukocytes. The urine was negative. During the previous year he had had a great many attacks of asthmatic bronchitis. The mother stated that they occurred once very three or four weeks. Previous to this time there had been very frequent colds—so many that the boy’s attendance at school had been practically nil. The mother had discovered that sugar did not agree with the child, and very little had been given. He was very fond of red meat, however, and wanted it three times a day. It was given twice a day. A liberal diet of green vegetables, fruits, milk, and cereals was ordered. In addi- tion, egg or bacon was to be given for breakfast, red meat three times a week, poultry three times a week, and fish once a week. Sugar was excluded absolutely, saccharin being used. Aspirin in 3-grain doses was given after each meal, with 5 grains of bi- carbonate of soda. This was the treatment for three months, during which time there was one attack of the asthmatic bronchitis. This responded to ipecac, antipyrin, and sodium bromid. Except for one or two slight colds, the boy experienced no trouble during the ensuing winter and lost but little time at school. At the end of seven months he had gained 7 pounds. The bicarbonate and aspirin were given continuously for three months. Then for a long period they were given alternately, each for five days, i. e., 3 grains of aspirin three times daily for five days, then 5 grains of bicarbonate of soda twice daily for five days. In the so-called sensitive type of cases the paroxysm typically occurs preceding the bronchitis as a result of the irritation from plant pollen or the emanations of animals or flowers and often takes the form of hay- fever as well as asthma. Hay-fever and asthma due to pollen allergy are rarely seen in children under five years of age. For a description of an exceptional case of this type seen by the senior author in consultation we are indebted to the child’s physician, Dr. Murray Bass. Baby W., female, third child, was the daughter of a mother who had suffered from hay-fever for which she had received prophylactic treatment, having exhibited sen- sitivity to June grass and ragweed. At the age of six and a half weeks the baby began to show signs of wheezing and mild cough. This grew progressively worse until the child had many attacks of cyanosis and extreme dyspnea. At no time did she run any temperature. Physical examination showed marked asthmatic breathing and sibilant rales over the entire chest. x-Ray of chest failed to show any abnormality. Differential blood count showed an eosino- philia of 23 per cent. Skin tests on the baby showed her to be sensitive to orchard grass, timothy, June grass, redtop and mildly to horse dander. Treatment consisted in stopping breast feeding, the use of large doses of adrenalin and atropin, and oxygen inhalations. Two treatments of exposure of chest to x-ray were also given with the idea that there was possibly an enlarged thymus, in spite of negative x-ray. After four weeks of severe illness, in several paroxysms of which the child seemed to be moribund, she gradually recovered. “At the present time she is gaining in weight, taking food well, though the chest still shows many rales and the eosinophilia persists.” ACUTE SPASMODIC BRONCHITIS; BRONCHIA*L ASTHMA 351 After several attacks of asthma associated with bronchitis what is sometimes called a true asthma results. Through the direct irritation, dependent on peculiar susceptibility to emanations such as those from cats or horses, or otherwise reflexly because of the presence of abnormalities in the upper respiratory tract, the habit becomes once established and there- after but very little irritation appears necessary to precipitate an attack. While these seizures may occur without clinical bronchitis, in not one of them will the bronchi be found normal, and the intolerance for carbohy- drates is to be considered as in the cases in which clinical bronchitis is in evidence. As the study of asthma progresses the number of cases classed as sensitive is steadily becoming larger. Pathogenesis.—In the motor nerve supply of the bronchial musculature are constrictor and dilator sets of fibers, and the bronchospasm typical of asthma is induced by irritation of constrictor fibers derived from the vagus. This effect may be induced whenever the mucosa of the upper air passages is irritated by a protein to which the subject is sensitized. In susceptible children the irritant effect may be manifested also by vomiting. In many instances this occurrence is a protective phenomenon to be desired.1 It may readily be understood that if the nasal passages are obstructed by adenoids, hypertrophied turbinates, or septal deformity the local susceptibility to irritant substances is correspondingly augmented. Dur- ing the actual attack the accumulation of tenacious secretion in the bronchi increases the degree of obstruction and only when expectoration is possible is prompt relief obtained. The sputum, when obtainable, is found to be transparent, usually showing “tapioca-like masses” known as Laennec’s pearls, together with a high content of eosinophils. Charcot- Leyden crystals, casts, and Curshman’s spirals are found more rarely. While the dyspnea is pronounced at the height of the paroxysm and vital capacity is lessened, systemic effects due to the extreme cyanosis are observable, but, characteristically, as soon as the attack has sub- sided (provided the asthma is uncomplicated), the lung capacity and al- veolar carbon dioxid content are found to be normal. It is conceivable that endocrinology may in the future contribute to a better understanding of asthmatic phenomena. Pathology.—Peribronchial thickening associated with chronic bron- chitis and various grades of tracheobronchial adenopathy comprise the effects induced in subjects of prolonged asthma. Secondary infection with bacteria, particularly various strains of streptococcus adds to the chron- icity of many cases. Tuberculosis complicating asthma in childhood, while not rare, is less frequent than one would expect from the contributing factor of bronchitis present in so many asthma cases. Treatment.—The management of a case of asthma in an infant or young child depends upon the nature and severity of the seizures. In a very urgent case 3 to 5 minims of a 1 : 1000 solution of adrenalin may be given hypodermically to a child from two to six years of age. Morphin with atropin may also be necessary in severe cases for the purpose of relieving the patient during the height of a paroxysm. In the cases in which bronchitis is prominent medication by mouth is of much service. 1 J. C. Walker: Oxford Medicine, II, Chapter VII. 352 THE PRACTICE OF PEDIATRICS For a child six months of age the following prescription has been found useful: Syrupi ipecacuanha gtt. xviij Antipyrina; gr. vj Sodii bromidi gr. xviij Syrupi rubi idsei 3v Aqua? q. s. ad. 36 M. Sig.—One teaspoonful every two hours—six doses in twenty-four hours. For a child one year of age: 1$. Syrupi ipecacuanha; gtt. xxiv Antipyrinse gr. xij Sodii bromidi gr. xxiv Syrupi rubi idsei 3v Aqua;.. q. s. ad. 56 M. Sig.—One teaspoonful at two-hour intervals—six doses in twenty-four hours. For a child from two to three years of age: 1$. Syrupi ipecacuanhse gtt. xxxvj Antipyrina; gr. xviij Sodii bromidi gr. xxxvj Syrupi rubi ida;i 3v Aqua; q. s. ad. 56 M. Sig.—One teaspoonful in water at two-hour intervals—six doses in twenty- four hours. Added relief will be afforded by steam inhalations, as described under Spasmodic Croup (p. 333). If the condition is urgent, the inhalations may be given for thirty-minute periods with thirty-minute rest intervals. Mustard, in the proportion of 1 part of mustard to 2 parts of flour (p. 846), so applied as to envelop the entire thorax, will often re- lieve the spasm sufficiently to reduce the respirations from 10 to 20 a minute. The mustard should remain on long enough to redden the skin, and should not be repeated oftener than once in four hours. The cold-air treatment in bronchial asthma is contraindicated re- gardless of the age of the patient. Warm, moist air at from 68° to 70° F. is best. A sudden blast of cold air may be sufficient to increase the se- verity of the paroxysms to a marked degree. Ventilation, however, is a necessity in these cases. The best means of obtaining it is by the use of two rooms, one of which may be aired while the other is occupied. Before the child is changed to the aired room its temperature should be raised to that of the other. In older children after the fifth year the bronchial spasm may be considerable, and more active measures may be required to furnish tem- porary relief. Here the methods usually employed for the same purpose in adults may be brought into use. A few whiffs of chloroform will often be effective. Fumes of nitrate of potash paper will sometimes be of service. At this age, also, a combination of antipyrin and bromid of soda may be brought into use. For a child from five to ten years of age 3 grains of antipyrin with 6 to 10 grains of bromid of soda, repeated in two hours, will often obtain a cessation of the paroxysm. As soon as the spasm subsides the sedatives should be discontinued. We have almost ACUTE SPASMODIC BRONCHITIS; BRONCHIAL ASTHMA 353 never found it necessary to give morphin hypodermically or otherwise in these cases. Illustrative Case.—In a very severe case, in a girl eight years of age, a combination of antipyrin and codein in full dosage was required to control the paroxysms. She was given \ grain of codein and 4 grains of antipyrin at two-hour intervals until three doses had been given. Before instituting interval treatment all growths and deformities in the rhinopharynx should be removed or corrected and the child given a suitable living regime. Inasmuch as it is often impossible to differentiate the two types of asthma clinically, it would seem advisable to do the protein skin reactions on all cases in which there is a possibility of existing sensitivity. The great majority of cases will be found to react to one or more of a relatively small number of substances. The following list includes all except the more unusual causes: Inhaled Materials. Ingested Materials. Horse dander. Rabbit hair. Cat hair. Dog hair. Sheep wool. Chicken, duck, and goose feathers. Cotton seed. Orris root (talcum powder). Pyre thrum (insect powder). Wind-borne pollens which vary in different localities. Egg-white (ovomucoid). Egg-yolk. Milk (lactalbumin, casein). Wheat (gliadin). Barley. Cocoanut. Veal. Pea. Crab. Rhubarb. Rice. Chicken. Carrot. Spinach. Banana. Corn. Cocoa. Bean. Peanut. Lobster. Strawberry. Rye. Lamb. Celery. Tomato. Orange. Oat. Beef. Beet. Potato. Oyster. Mustard. Almond. Pork. Lettuce. Clam. Prune. Cooke1 has found a large number of patients reacting to the dust found in their home environment. Technic of Skin Test.—In making the cutaneous tests the scratch method devised by Schloss and Walker is to be pieferred. An area on the back or chest in a baby, or the flexor surface of the forearm in an older child is cleansed with alcohol, and a scratch § inch long is made with a large Hagedorn needle. On this scratch is placed a drop of hundredth- normal sodium hvdroxid and a small amount of the dried extract is dissolved in this drop. In fifteen to twenty minutes the site is gently cleaned with separate twists of cotton and the reading made. A positive reaction varies with the material used. The pollens usually give the larg- est reaction, the inhalants the next largest, and the ingested substances the smallest. A small reaction may have as much clinical significance as a large one. In interpreting the results a simple erythema alone or accompanying a small round wheal less than 0.5 cm. in diameter is noted as “ =*=Wheals with irregular outline from 0.5 to 1 cm. in diameter as and for each half centimeter more of diameter a plus mark is added. Doubtful tests must be repeated several times before a definite conclusion is reached. 1 Studies in Specific Hypersensitiveness, III, Jour. Immunology, March, 1922. 354 THE PRACTICE OF PEDIATRICS Interval Treatment.—For the bottle fed this consists in reduction of the sugar to one-half the amount suitable for the age, and the use of 1 grain of bicarbonate of soda for each ounce of the milk food given. The bowels must be kept properly open, although constipation or intestinal toxemia has seldom appeared to us to be a paramount factor in the asthma of children. The interval treatment for older children is most important, for by it one may postpone the attacks. Since these cases, as has been indicated, are usual in lithemic subjects, the scheme of management followed out is to some degree the same as for rheumatism, chorea, recurrent bronchi- tis, and cyclic vomiting. Sugar is reduced to a minimum, and red meat is given not oftener than every second day, and then only in moderate amounts. The child’s protein nutrition is maintained by the use of a high protein cereal, such as oatmeal, and purees of dried peas, beans, and lentils. The eating of green vegetables is encouraged. Food between meals is forbidden. Fruits are used in moderation and an active outdoor life is encouraged. At bedtime the child is given a brine bath (p. 843), followed by a vigorous dry rub. The mother or attendant is instructed that one bowel evacuation daily must be insured. The best method is so to regulate the life of the patient as to avoid contacts with the particular protein or proteins to which the child is proved sensitive. In those cases in which the reaction to one or more proteins is definitely proved, immunization may be attempted by those skilled in this work. It is good practice in all cases of true asthma or those in which there is a manifest tendency to a bronchitis with associated spasm to advise the removal of all feather pillows, hair mattresses, and sachet and dusting- powders from the environment of the patient, for the reason that such children may be sensitized in a minor degree sufficient to produce a bronchial reaction and show no response to the usual skin tests. There is no doubt that certain subjects who are “poor oxidizers,” with a defective metabolism, the so-called lithemic class, are benefited in a prophylactic way when given a diet containing a meager allowance of fat and sugar. A child overfed on a diet rich in these substances reacts by developing a weakened resistance of the respiratory tract which, in turn, allows a bacterial invasion which we believe to be responsible for much unexplained asthma. Additional help will be supplied these children by the periodic use of bicarbonate of soda in dosage of 10 grains three times daily on alternate weeks. Hay-fever in older children is by no means a rare disease. Our youngest patient was three years of age. The disease is due to the influence of plant pollen on the mucous membrane of the nose and throat and represents a pollen protein anaphylaxis. A hay-fever subject may be sensitized to one or half a dozen pollens. The pollens of ragweed and the grasses are perhaps the pollens most frequently causing hay-fever. Heredity appears to play an important part in the etiology. Oppenheimer and Gottlieb1 reported that in 90 POLLINOSIS, POLLEN DISEASE, HAY-FEVER 1 Medical Record, March 18, 1916, PNEUMONIA 355 per cent, of their cases members of the family of the patient suffered with ailments showing manifestations of anaphylaxis. Diagnosis.—The disease may manifest itself any time during the period of the flowering of plants. The first sign is usually that of profuse lacrimation with itching and burning of the eyes. Sneezing and a profuse watery nasal discharge are rarely absent. In many cases later asthmatic seizures develop. The seizures continue in a given case while the individual is sub- jected to the action of the pollen to which he is sensitized. The disease may continue during the entire period from May until October. The Skin Test.—Individuals who are sensitized to a pollen will usually show a cutaneous reaction to the pollen protein. The technic of the test has been described on page 353. Cooke and Yanderveer have mentioned 25 plants which they personally proved had caused hay-fever. Treatment.—Those who desire to treat hay-fever by the use of pollen preparations are advised to consult the publications of Cooke and Vander- veer, Walker, and MacKenzie. Pneumonia is an infective process, due to bacterial invasion, seen with the greatest frequency in the young. The influence of cold, which is that of shock, producing a lowered resistance, temporarily makes the individual unusually susceptible to the infecting organisms, which are ever present. On account of the different ways in which these infecting agents manifest themselves in the lungs, two types grossly are produced— lobar or fibrinous -pneumonia and broncho- or catarrhal pneumonia. PNEUMONIA Lobar Pneumonia Lobar pneumonia is an acute infection of the lungs, primary in char- acter, and may occur at any age. Until the second year it occurs less frequently than bronchopneumonia. Etiology.—The influence of cold is to produce a lowered resistance. Exposure may therefore play a part. The disease occurs with greatest frequency during the winter and spring months. Bacterial Etiology.—The specific etiologic cause of lobar pneumonia in a large majority of cases is the pneumococcus (Diplococcus pneumoniae, Micrococcus lanceolatus) of Frankel1 and Weichselbaum.2 This has been definitely established by a large number of independent workers. In the Rockefeller Institute series of 529 cases the Diplococcus pneumoniae was isolated in 454 instances. From the remaining cases were cultured out the Friedlander pneumobacillus, Bacillus influenzae, Streptococcus pyogenes, Streptococcus mucosus, Staphylococcus aureus, and mixed growths. The pneumococcus is an encapsulated, Gram-positive, lancet-shaped diplococcus, which grows fairly easily in artificial media, especially defib- rinated blood media, and is characterized by solubility in bile.3 For 1 Frankel, A., Zeit. f. klin. Med., x, 1886. 2 Weichselbaum, Med. Jahrbucher, Wien, 1886. 3 Neufeld, F., Zeit. f. Hyg., xxxiv, p. 454, 1900. 356 THE PRACTICE OF PEDIATRICS further morphologic, cultural, and staining characteristics the student is referred to standard text-books on bacteriology. In 1910 Neufeld, who had previously demonstrated the production of precipitins and agglutinins by the pneumococcus,1 found that the immune reactions within the pneumococcus group varied.2 Following out this line, Dochez and Gillespie3 divided pneumococci into four groups according to their immunologic reactions with homologous sera. Types I, II, and III are the fixed strains showing homologous immune reactions, although Type II shows atypical strains. Type III is the pneumococcus mucosus. Type IV is a heterogeneous group with no definite constant immune reactions. The incidence and mortality of the four groups as reported in the Rockefeller Institute series are as follows: Incidence, Mortality, Type. per cent. per cent. I 33 25 11 31 32 Ill 12 45 IV 24 16 An efficient therapeutic antipneumococcic serum for Type I is avail- able.4 Antisera for the other types have not proved effective. Pneumococci are found in great numbers in the sputum. Pneumo- coccemia, as reported in various series, can be demonstrated in 10 to over 50 per cent, of the cases. The presence of a pneumococcemia makes the prognosis more grave. Specific immune substances are present in the urine in a large percentage of cases.5 Predisposition.—Lobar pneumonia in the young is not a disease of the weak. This type of child is the subject of bronchopneumonia. It is just as often the strong, vigorous child who develops lobar pneumonia. Pathology.—The most apparent effects of the disease are those pro- duced in the pulmonary tissue, where there is an exudative inflamma- tion which progresses through four well-recognized stages, to which are applied the terms: (1) Congestion; (2) red hepatization; (3) gray hepatiza- tion, and (4) resolution. These stages are not always clearly defined; and not infrequently, at postmortem, neighboring portions of a lung simultaneously present the appearances characteristic of two or more stages of the same inflammation. Congestion, consolidation, and reso- lution have, however, a very constant order of occurrence, and this is well understood when one considers the exudative nature of the inflam- matory process. In the primary stage of congestion the involved portion of the lung is the seat of active hyperemia and edema, and becomes darker in color and acquires increased consistence. The alveolar capillaries are tur- gid, and the epithelial cells lining the air-spaces are swollen. In the stage of red hepatization a well-marked exudation into the alveolar spaces ensues. The exudate consists chiefly of fibrin, red blood-cells, leukocytes, 1 Neufeld, F., Zeit. f. Hyg., xi, 1902. 2 Ibid., u. Handel, Arb. k. Gsndhtsamte, xxxiv, p. 166, 1910. 3 Dochez and Gillespie, Jour. Amer. Med. Assoc., lxi, p. 72, 1915. 4 Avery, Chickering, Cole, and Dochez, Rock. Inst. Monograph No. 7, 1917. 5 Ibid. PNEUMONIA 357 and desquamated epithelial cells. The involved lung structure thus becomes practically solid and roughly resembles liver. The pleurisy, the swelling and heaviness, and the packing of the alveoli are all most marked during the red stage. During the stage of gray hepatization the alveoli become choked with additional exudate, which consists chiefly of leukocytes, the blood-vessels undergo compression, and the lung mass becomes swollen and heavy, and assumes a gray appearance. The pleura shares in the inflammation and at this period is coated with more or less fibrinous exudate. The stage of resolution marks the change by which the air-cells are relieved of their burden and the normal circulation is restored. This process is essentially one of autolysis, involving disinte- Fig. 70.—Lobar pneumonia of right middle lobe. (Dr. C. H. Perkins.) "ration of the fibrin meshes in the exudate and degeneration of the masses of leukocytes and desquamated epithelial cells. Much of the liquefied exudate is coughed up directly, but more is absorbed and eliminated through the agency of the lymphatics. Eventually the normal lung structure is restored except in those instances in which the occurrence of interstitial exudate has facilitated the development of abscess or gangrene, or the usual dry pleurisy has been superseded by inflammation of the purulent type—empyema. In cases of typical lobar pneumonia the pneumococcus present in the circulating blood may give rise to localized abscesses or such fatal complications as peritonitis and meningitis. 358 THE PRACTICE OF PEDIATRICS Localization of the Lesions.—Orth’s figures for the localization of lobar pneumonia are: 52 per cent, for the right side. 33 per cent, for the left side. 15 per cent, for both sides. In 217 cases (Koplik) the right lung was involved in 124 and the left in 93; the upper right lobe in 74, the upper left in 35, and the upper lobe of either lung in 109 cases, as against 100 cases for the lower lobes. Occasionally the central portion of a lobe alone may be involved. The existence of small foci of consolidation is, however, far more characteristic of bronchopneumonia. In lobar pneumonia the lesion is peculiarly distinct and circumscribed, the surrounding lung portions remaining uninvolved. In double pneumonia a portion or the whole of one or more lobes in each lung is involved. Fig. 71.—Temperature chart, lobar pneumonia. Symptoms.—The onset of the disease is sudden, with fever and rapid respiration, which may range from 40 to GO and is usually accompanied by cough. The temperature is variable—over 102° and under 105° F. The pulse is rapid—130 to 160—and there is considerable. prostration. The ratio of respiration rate to pulse rate is high. These are the only symptoms distinctly indicative of lobar pneumonia. Vomiting, convulsions, stupor, and chill, to which much attention is given by writers, occur with many other diseases, and in some cases of pneumonia; thus, in the writer’s cases convulsions have ushered in the disease in 2 per cent.; vomiting in less than 10 per cent.; chill in about 5 per cent. Loss of appetite, coated tongue, and drowsiness are, of course, noted, and these are all present in dozens of ailments. The prostration is most marked for the first forty-eight hours. After this time the organism appears to adjust itself to the changes induced PNEUMONIA 359 by the infection. During the first or the second day of illness the tem- perature becomes established at a high point—103° to 105° F.—where it remains, usually with slight variation in a recovery case, until the crisis. This steady high range of temperature (see Fig. 71) is not always fol- lowed out, the fever in many cases fluctuating considerably. Illustrative Case.—In an eight months’ old child the temperature was that of a typ- ical malaria, 99° F. in the morning, 104° to 105° F. in the late afternoon. The crisis occurred on the eighth day, and the child was promptly well. Thorough examination from every standpoint failed to show other than a lobar pneumonia. The respiration per minute depends upon the amount of lung in- volved, the virulence of the infection, and the age of the patient. In children under two years of age, from 60 to 80 respirations per minute are not at all unusual. In older children the respiration is less rapid, often not exceeding 60 per minute. The pulse in young children is in like manner more accelerated—a range from 150 to 180 is not unusual, while in children after the third year the rate may not be above 160. Duration of the Attack.—The duration is variable. In the event of mild infection, probably associated with good resistance, many patients make the crisis on the third day, even before the physical signs are posi- tive. Such cases are by some authors said to represent the abortive type. In the average recovery case the crisis occurs from the fifth to the ninth day. A crisis delayed beyond the ninth day means a very serious infection and a very grave prognosis. Recovery cases in which the crisis does not occur until the eleventh day are not extremely rare. In one instance the crisis transpired on the thirteenth; and in another on the fifteenth day. Unfavorable Symptoms.—The most unfavorable symptom in lobar pneumonia is a low temperature in the presence of the other character- istic signs—rapidity of respiration, rapid pulse, and prostration. Illustrative Case.—The senior author was called by a practitioner in a New York suburb to see a case of pneumonia that disturbed him greatly, although it was im- possible to make the parents understand that the child was severely ill. There was no elevation of the temperature—in fact, it was slightly subnormal. The patient, who was ten months old and had been previously healthy, showed marked pallor and pros- tration not unlike that presented by an acute gastro-intestinal intoxication case, such as is frequently seen in summer. The respiration was about 40 and the pulse was rapid and weak. There was nothing to account for the illness other than a frank consolidation of the right lower lobe. The writer made a fatal prognosis, recognizing the probability of death in a few hours. The child died twelve hours after the visit. In this case the child was overwhelmed by the pneumococcus infection, so that any reaction indicated by fever was impossible. Cases of this kind in vigorous children are rare. In athreptics and those older children who suffer from malnutrition or who develop pneu- monia after a previous exhausting disease the low temperature range— 100° to 102° F.—is not at all unusual. With it will often be associated petechial skin eruptions. In such instances the prognosis is most un- favorable. Tympanites.—The development of marked abdominal distention is a symptom of grave import, indicating a high grade of toxemia. Further, the distention interferes not a little, mechanically, with the already embarrassed respiration. 360 THE PRACTICE OF PEDIATRICS Vomiting and diarrhea are usually occasioned by improper feeding. Uncorrected, they add to the dangers of the disease. Stupor and delirium are cerebral evidences of the systemic toxemia, and! while they indicate a severe infection, their presence is more con- fusing in a diagnostic sense than an indication of danger to the patient. The symptoms are traditionally more active, particularly the temperature manifestation, when the right apex is involved. Such a localization, however, has no influence on the prognosis. Delayed Crisis.—Every day after the ninth, without the critical drop, adds to the danger to the patient. Lobar pneumonia is rarely fatal before the ninth day. Deaths, of course, occur earlier, due to the severity of the infection, but this is very exceptional. Among 6 fatal cases at the New York Infant Asylum in a six months’ service, 2 terminated on the eighth day, 2 on the ninth, 2 on the twelfth, and 1 on the twenty-first day of the disease. In the cases of long duration we have to deal with a condition in which the individual is not able to manufacture sufficient antitoxin to destroy the infecting agent or agents, and the question naturally arises, will he be able to do so. Complications.—The advent of a complication adds a more serious aspect to the disease. A complication may appear at any time during an attack, and change what appears to be a favorable case into one of the greatest gravity. The complications that have occurred under our observation are as follows: myocarditis, pericarditis, pneumococcus meningitis, pneu- mococcus peritonitis, empyema, peri-arthritis, otitis, pulmonary ab- scess, and pulmonary gangrene. Myocarditis.—In very severe infections in which the temperature has been high a decided irregularity of the heart action develops. Al- though no cyanosis or other indication of general heart failure may be apparent, the first sound will be weak and incomplete. Pericarditis.—Fluid, serous or purulent, is more often discovered at the autopsy than recognized during the illness, and is more common in left-sided empyema. Cases have been observed postmortem which showed the pericardial sac filled with pus and fibrin, and the heart sur- rounded with the exudate so as to be scarcely recognized, although no cardiac sign had been present during life, other than that both sounds were defective. Meningitis of pneumococcus origin (p. 603) is not at all unusual among hospital and asylum patients. An invasion of the meninges by the pneu- mococcus produces characteristic symptoms (p. 604) quite apart from the usual manifestations of pneumonia, so that, recognition of this com- plication is readily made (Plate I). Further, when the meninges are attacked, the resulting symptoms are very active. At once there may be noted slow, irregular respiration, slow, irregular pulse, stupor from which the child may not be aroused, and change in the pupils. Peritonitis.—Persistent distention of the abdomen, with evident pain on pressure, and obstinate constipation are indications of acute peritonitis. In our experience these cases have all been fatal. PNEUMONIA 361 Empyema (p. 388) may develop during the pneumonia, in which case the chief manifestation will be a change in the physical signs—the bronchial breathing and bronchial voice changing suddenly to weak, distant bronchial sounds, associated with flatness on percussion. Empyema, however, is more apt to follow a day or two after the crisis than to occur during the active stage of the disease. It is a com- plication seen in a large number of cases in different stages of the disease, and the possibility of its development should never be forgotten. Peri-arthritis will be made evident by pain and swelling of a joint, most frequently the shoulder or elbow. Otitis is often overlooked because of the absence of pain to locate the trouble. It often passes unrecognized until a rupture of the drum occurs, the fever being accounted for by the lung disease. Mastoiditis may develop unsuspected. In every disease of infectious origin the ears should be subjected to a daily otoscopic examination. Acidosis in Lobar Pneumonia: Illustrative Case.—A child eighteen months of age developed fever, prostration, and rapid respirations, the typical hyperpnea of acidosis, active deep urgent breathing, in marked contrast to the usual quiet superficial sighing, though rapid, respirations of lobar pneumonia. A heavy trace of acetone was found in the urine and the acetone breath was very noticeable. The chest signs were sufficient for a diganosis of pneu- monia, but the child died from unmistakable acidosis. Prognosis.—This in private cases depends considerably upon whether the patient is under care in a sensible family, or subject to ignorant manage- ment. If the physician has the right support the mortality is very low— from 2 to 3 per cent. Among the ignorant and careless it will be higher— from 5 to 10 per cent.—approaching the mortality in hospitals and chil- dren’s institutions. The high mortality in hospitals is due more to the wretched condition in which the patient arrives than to peculiarly severe features of the disease. In infant asylums and children’s institutional homes a lack of resistance to disease is the rule, and pneumonia affords no exception. Diagnosis.—Recognition of the disease in infants and young children is surrounded with few difficulties. The sudden onset of illness, with high fever, rapid respiration, dilatation of the alse nasi, expiratory grunt, and rapid heart action, are objective signs of real significance. Consolidation of the lungs makes the diagnosis positive. The time of appearance of this sign is, however, subject to considerable variation. It may be present during the first twenty-four hours, but is repeatedly delayed to the fourth day. Rarely consolidation may appear as late as the fifth day. In one case showing very active symptoms otherwise the typical physical signs referable to the lung were not apparent until the seventh day. On the day the consolidation appeared crisis occurred. Cases of this type may go through the entire course of the disease and never show definite consolidation. Such pneumonia was formerly referred to as “central.” Mason, of New York, has demonstrated by Roentgen-ray studies that these cases are really those of marginal pneumonia. There is no doubt but that a pneumococcous infection of the lung may exist for several days and run its entire course without the process ever going 362 THE PRACTICE OF PEDIATRICS on to consolidation demonstrable by our usual means of examination. We know that this is possible in the two- or three-day cases representing clinically the so-called abortive type. The Physical Signs.—As already indicated, auscultation may never reveal a sign of the disease other than harsh or sonorous breathing. As a rule, the infiltration of the air-cells will develop sufficiently from the second to the fourth day to produce bronchial breathing and bronchophony. Over the consolidated area fine pleuritic friction rales will usually be heard at the height of inspiration when the consolidation makes its ap- pearance. In practically every early case of lobar pneumonia the pleura over the consolidated surface is dry and injected, often showing post- mortem a very fine exudation. Percussion will show dulness, depending in degree and extent upon the nature and distribution of the lesion. Absolute dulness will be present only over the consolidated area. The chief value of percussion is in differentiating the presence of fluid from extensive fibrinous exudation, a condition sometimes desig- nated as pleuropneumonia. Palpation is of little value in examining children, and reveals nothing that may not be learned through auscultation and percussion. In diagnosing considerable exudations of fluid in the pleural cavity and pneumothorax, the absence of vocal fremitus may furnish corrob- orative evidence. The agent to-day of greatest value in detecting and diagnosing pul- monary consolidation is the x-my. This should be employed when pos- sible, particularly in all obscure cases. Differential Diagnosis.—Lobar pneumonia is to be differentiated from bronchopneumonia, from acute pleurisy with massive output of fluid, and from similar cases in which the fluid is less in amount. The differentiation between lobar pneumonia and bronchopneumonia is dis- cused on p. 373. Pleuritic Effusion.—When there is a fluid, pleuritic exudate suffi- cient to fill the entire cavity, with the fluid under pressure over a com- pressed and consolidated lung, signs will be transmitted to the chest wall closely resembling those of frank consolidation. Thus, there may be bronchial breathing and bronchophony of a very intense character over the entire involved side anteriorly and posteriorly, at both the apex and the base. Repeatedly these signs are interpreted by the attending physician as evidence of a complete consolidation of the lung. It is to be remembered that a lung is almost never entirely consolidated in acute pneumonia. Furthermore, in the presence of a massive fluid exudate percussion will elicit flatness over the entire region. When the process is located on the left side, the heart displacement to the right indicates the presence of fluid in the left pleural cavity. In cases of effusion, finally, there is an absence of friction-sounds and likewise of rales. When doubt exists, as is sometimes the case even after the use of the £-ray, which does not invariably differentiate fluid from consolidation, exploratory puncture should always be made. Fluid in lesser amounts is indicated by diminished respiratory sounds, localized flatness, the absence of mucous or pleuritic rales, and displacement of PNEUMONIA 363 the heart if the exudation is in sufficient amount. Only in cases in which the pleural cavity is absolutely filled with fluid do we find the voice and respiratory signs of frank lobar pneumonia. Blood-findmgs in lobar pneumonia are of special diagnostic signifi- cance (see p. 433.) Treatment.—Our efforts in restoring the patient to health are sup- portive only. When a child is stricken with lobar pneumonia, our first effort should be to place him in such a position that he may to the best advantage cope with the enemy. In order to do this every detail of his daily life should so be arranged as to assist all the organs of the body most favor- ably to combat the changed conditions produced by disease. Telling the mother what to do for the fever and writing a prescription for a cough mixture is a most careless method, worthy of the prescribing apothe- cary rather than a physician. A proper regime must be established as soon as the child becomes ill. The bowel function, the room temperature, ventilation, and sleep, as well as special medication, are all to be con- sidered. The child’s comfort demands the avoidance of everything causing restlessness or irritability. Open Air.—For strong robust children the cold-air treatment is to be advised. These patients unquestionably do better with the win- dows wide open day and night. In such an atmosphere the respiration is slower, the heart action is stronger, and the patients are much more comfortable, sleep better, and make a more satisfactory convalescence. A woolen hood and suitable woolen clothing should be worn. The Sick-room.—When the open-air treatment is not practicable, the temperature of the room should be kept at 61° to 65° F. both day and night, wide fluctuations in the temperature being prevented. A large room, if at hand, should always be selected, and there must always be direct communication with the open air by an open window. The child should be kept in the crib, and not held on the lap of the mother or nurse. Quiet should be maintained in the sick-room, only those in attendance upon the patient being admitted. The presence of curious visitors annoys the child and takes away a certain number of strength units, which may determine the outcome of the case. The advantages of the cold-room or roof treatment in this respect are obvious. The Clothing.—This should be the usual night-clothing. We have long since discarded the oiled-silk jacket or any special form of covering. Such applications are very easy to put on, but very difficult to take off with safety; further, they tend to elevate the temperature of the patient, make him uncomfortable, particularly during convalescence, and pre- vent the free action of the skin. The Bowels.—There should be a standing order for an enema to be given if the bowels do not move once in twenty-four hours; \ to 1 grain of calomel in doses of £ grain every hour is usually of consider- able service. In a case in which there is very high fever this dosage may be repeated every three or four days. Counterirritation.—Early in the attack, when there is pain, a mustard plaster—one-third mustard and two-thirds flour—mixed to a paste, spread on cheese-cloth, and placed over the involved area for a few mo- 364 THE PRACTICE OF PEDIATRICS ments, will give signal relief and may be repeated at intervals of from four to five hours. This form of counterirritation is also useful in the convalescence of delicate children when the lung clears slowly, and exam- ination reveals feeble breathing and many mucous rales. In such cases two or three applications daily until the lung clears will suffice. Each application should be maintained until the skin is well reddened, and if this does not occur within ten minutes, the mixture of mustard and flour should be made stronger, one part mustard to one part flour. In a few cases of delayed resolution dry cups daily, applied directly over the involved areas, have been of much service. The Diet.—(See Diet in Illness, p. 154.) Management of Pyrexia.—Whether or not antipyretic measures are to be used, and the nature of the antipyretic to be advised, depends upon the case and the family possibilities relating to care and nursing. One child will bear a temperature without inconvenience which would seriously compromise the chances of recovery of another, so that the thermometer is not a sufficient guide unless the effect of the fever upon the patient be considered. Some children will be delirious and restless and will need antipyretic treatment when the fever is at 103° F., yet a temperature of 104° F. rarely calls for interference. A rise of 1° F. usually means an increase of 20 to 30 heart-beats per minute. We prefer, there- fore, that the temperature should not go above 105° F., even if at the time the child shows but little inconvenience. Cold water, intelligently applied, is the best means of reducing fever. The water may be used either in the form of a sponge-bath or a cool pack. The sponge-bath (p. 840), repeated at intervals of from two to four hours, suffices in a few cases in which the temperature is readily influenced. As a rule the cool pack (p. 841) will be required, especially if the fever is particularly high. The sponge-bath, while not controlling the fever as well as does the pack, possesses the advantage of safety even when administered by the most ignorant. The procedure really amounts to nothing more than sponging the entire body with cool water or alcohol and water. The cool pack requires a trained nurse or an intelligent mother, either of whom should be instructed by the physician as to its use. When cool water is properly applied, and the packs or baths agree, the child, previously restless and perhaps delirious, falls into a quiet sleep; the temperature falls two or three degrees, the pulse becomes slower and fuller, and the respiration less frequent. We have never seen a carefully given pack or bath do harm. In fact, the water is so grateful to the patients that, when old enough, they often ask to have the towel made cooler when it becomes warm and dry from the heat of the body. Management of Tympa?iites.—Persistent abdominal distention even without peritonitis is one of the danger signs in pneumonia and signifies an extreme degree of toxemia. Measures to combat the condition should be adopted early in the case and procedure found effective should not be relaxed. The less serious degrees of distention are relieved by the use of stupes applied to the abdomen while a rectal tube is kept in the bowel to allow escape of flatus. The coincident administration of spiritus setheris compositus in doses of 5 to 10 minims given hourly by mouth may also be of service. Daily hot saline colon irrigations or continuous enteroclysis PNEUMONIA 365 by the Murphy method should be employed not only for the beneficial effect on distention, but to promote absorption of fluid if little is being taken by mouth. For extreme degrees of distention with almost complete enteroparesis, physostigmin or pituitrin hypodermically are indicated. The latter is probably safer and in our experience has proved more effective. The dose of pituitrin for a child at least three years old ranges from 3 to 5 minims. This dose may be repeated after an hour if necessary. Heart Stimulants.—A child must never be given a heart stimulant simply because he has pneumonia. Only when the pulse shows signs of weakness, great rapidity, irregularity, or reduced volume has the time arrived for stimulation. For a very rapid pulse, over 150, digitalis is the best stimulant. For a child from six months to one year old, 1 drop of the tincture may be given every two hours—at least six doses in twenty-four hours; for a child from one to three years old, 1 or 2 drops at intervals of two hours—at least six doses in twenty-four hours; for a child of three years or over, 2 or 3 drops at intervals of two hours—at least six doses in twenty-four hours. If the case is a very serious one, the digitalis may be given every two hours during the en- tire twenty-four, although if the conditions permit it is better to disturb the patient as infrequently as possible during the night. If digitalis disturbs the stomach, strophanthus may be employed. When the pulse is irregular and intermittent, with reduced volume, strychnin is justifiable. To a child from six months to a year old 1/300 grain is to be given every three hours—six doses in twenty-four hours; from the first to the second year, 1/200 grain at three-hour intervals— six doses in twenty-four hours; after the second year, 1/150 grain may be given at intervals of three or four hours—six doses in twenty-four hours. Children who are under strychnin medication should be carefully watched for signs of the physiologic effects of the drug, the first symptoms being an unusual susceptibility to sudden noise and a slight fibrillary twitching of the muscles of the face and the backs of the hands. Instruc- tions should be given, when these symptoms appear, to discontinue the drug until the next visit of the physician. We have repeatedly noticed these signs of the physiologic effects of the administration of strychnin, and they need cause no anxiety. They are actually necessary in order to get the full benefit of the drug. However, it is only in the most severe cases that this drug should be pushed to such an extent. When the circulation of the skin is deficient, involving coldness of the extremities and cyanosis, indicated by blueness of the finger-nails and lips, nitroglycerin is indicated. To a child under one year of age, 1/300 grain may be given at intervals of two or three hours—six doses in twenty-four hours; to a child from one to three years of age, 1/200 grain at three-hour intervals—six doses in twenty-four hours; after the third year, 1/150 grain at intervals of two or three hours—six doses in twenty-four hours. Nitroglycerin, if given in large doses, produces head- ache, of which older children will complain, while nurslings will show their discomfort by restlessness and crying. Caffein sodiosalicylate is also very useful in cases of this nature, and may with advantage be employed with the strychnin. The dos- 366 THE PRACTICE OF PEDIATRICS age for a child from six months to one year is \ grain. Camphor in the foim of the oil of camphor is useful hypodermically in the condition just described. It may be given in 1- to 2-grain doses and repeated in one to two hours. In collapse, 1 : 1000 solution of adrenalin hypoder- mically, administered in dosage of from 3 to 5 drops, is of much use. The ammonium preparations are not employed, because their admin- istration even for a short period invariably interferes with nutrition by diminishing the digestive capacity. Alcohol is often prescribed too early. Most cases of pneumonia pass through an entire attack without one drop of alcohol. This drug in any form should be avoided early in the disease. Later, when the case is doing badly, when the strychnin and digitalis, alone or in combina- tion, fail, the alcohol may be given, and then it may be a life-saving means. It is indicated at this time because it sustains the patient, and at the same time stimulates the heart when regular food assimilation is impossible. To a child under one year of age one may give from 8 to 30 drops of brandy at two-hour intervals; from one to two years of age, 15 drops to 1 dram at two-hour intervals; over two years, 1 to 2 drams at two-hour intervals. Patients who show profound sepsis will require and consume an enormous quantity of alcohol without showing the slight- est intoxicating effect. Illustrative Case.—During the senior author’s term as resident physician of the New York Infant Asylum a child fourteen months of age, ill with diphtheria, was given 4 ounces of brandy in twenty-four hours without showing signs of stupor or intoxication. Hypodermic Stimulation.—The use of the hypodermic stimulation sug- gested is to be advised in an emergency, or when the stomach becomes intolerant, or when it becomes evident that drugs administered by mouth are not absorbed. If the dietetic suggestions are carried out, and if dis- turbing drugs, such as the ammonium salts, heavy syrups, etc., are omit- ted, there will rarely be any occasion to resort to hypodermic stimula- tion. When indicated, the doses suggested for the stomach may be given hypodermically, with the exception that alcohol should not thus be given in quantities greater than | dram of brandy or whisky at one time. Atropin sulphate in dosage ranging from 1/500 to 1/200 grain may be given with good effect when the breathing indicates the beginning of pulmonary edema. This dose may be repeated after three hours. Oxygen exceptionally is of value (see p. 378). Gavage.—Cases are encountered in which, for a time, on account of the profound toxemia, no food or medicine will be taken. In such in- stances the giving of stimulants and predigested food by means of gavage (p. 853) will be of material assistance. The milk used should be com- pletely peptonized, and to it whisky, brandy, and stimulating drugs may be added. The forced feeding should not be used oftener than once in four hours, and preferably only once in six hours. When thus given the individual doses of the stimulants should be increased. The Murphy drip method of using normal salt solution is of service in cases in which feeding difficulties are insurmountable. Specific Medication.—There is no drug known which will cut short or abort an attack of lobar pneumonia. Mercury in the form of large PNEUMONIA 367 doses of calomel, quinin, salicylate of soda, and other drugs have no specific action. Conservation of the strength of the patient, combined with careful medication to meet special requirements as they arise, constitutes our treatment of lobar pneumonia, and has given a death-rate of only 2 per cent, in children under two years of age. During convalescence great care is needed in permitting the child to resume his usual habits of life, for in the matters of both food and exercise we must make haste slowly. Transfusion.—In long-standing cases of pneumonia in which the vitality of the patient is at an extremely low ebb and assimilative capacity is weak an opportune transfusion may determine recovery. The value of the pro- cedure is probably greater than is generally appreciated. The new blood no doubt has both a nutritive and an immunizing value. Illustrative Case.—A boy six years of age was gravely ill with lobar pneumonia of very severe type. When seen in consultation on the ninth day of the disease, he had been comatose for three days to such a degree that the giving of nourishment was difficult. The temperature continued to range from 105° to 106° F. without sign of impending crisis. Prostration was extreme. Under very free stimulation the heart was showing failure of response. Transfusion was suggested and carried out, 6 ounces of blood being given. In the few hours following the boy showed a better general reaction and on the next day crisis occurred, the temperature dropping to normal. Recovery was uninterrupted. It is, of course, impossible to say that the temperature would not have fallen without the transfusion. Similar experiences, however, in extreme conditions make us feel that this measure was of distinct service and that in transfusion we have a remedy that may carry the patient over the critical period when nature is doing her best without the outcome desired. Serum Treatment.—The serum treatment in small children is relatively unimportant because of the low incidence of fixed types of pneumococcus and the fact that most children withstand a Type 1 infection perfectly well. The serum heretofore employed is effective only in Type I pneu- monia and, inasmuch as the prognosis in lobar pneumonia in small chil- dren is usually good anyway, there are usually no indications for em- ployment of serum. In the occasional severe Type I infection its use is justified. The possibility of successfully treating pneumonia in childhood with pneumococcus antibody solution, which was first prepared by Huntoon in 1919, is of great significance. The method has already given encour- aging results in a considerable series of adult cases under the supervision of Cecil and Larsen,1 and Cecil and Baldwin. An aqueous extract of active immune substance from antipneumococcus serum is employed. This extract is apparently as potent as the ordinary antipneumococcus serum and possesses the distinct advantage of being practically free from the proteins of horse-serum. By reason of its poly- valent character antibody solution contains protective substances against Types I, II, and III of pneumococcus. Moreover, apparently good effects have attended its use in many of the Type IV cases which constitute the predominant group in childhood. The Felton serum represents a still more highly adapted protective antibody preparation and gives promise of greatest efficacy both in pre- vention and cure of pneumonia. 1 Jour. Amer. Med. Assoc., July 29, 1922, vol. lxxix, pp. 343-348. 368 THE PRACTICE OF PEDIATRICS Bronchopneumonia (Catarrhal Pneumonia) Bronchopneumonia is preeminently a disease of infancy. On ac- count of its large mortality, and because of its frequent occurrence as a complication of almost every other disease of infancy, it is one of the most formidable ailments which we are called upon to treat. The dis- ease is usually described as primary or secondary. The condition, when described as primary, usually follows a bronchitis—often a neglected bronchitis—and theiefore is properly to be termed a secondary condition. The severity of the disease varies considerably, depending on the age and condition of the child, the nature of the infection, and the amount of lung involved. It is most fatal when associated with diphtheria, measles, and pertussis. Catarrhal pneumonia demands our most careful attention not only on account of the delicate organs attacked, but because, unlike lobar pneumonia, scarlet fever, typhoid fever, and many other diseases of early life, this disease has no self-limitation, no cycle. While in treating the other diseases mentioned we are required only to assist a patient through the various stages, in case of catarrhal pneumonia we must do more, for here a cure is demanded and we are not aided by a tendency to spontaneous limitation. Etiology.—A great majority of the cases occur in children under two years of age. Over one-half of these patients are under one year of age. After the third year bronchopneumonia is unusual except as a complica- tion of measles or pertussis. A chief cause predisposing to broncho- pneumonia is, thus, the tender age of the patient, who, on this account, offers little resistance to the infection. Children debilitated from any cause are predisposed for a like reason. Whooping-cough and measles more than any other diseases predis- pose to bronchopneumonia. In a large number of fatal cases of marasmus and malnutrition, bronchopneumonia is the terminating illness. Bacteriologic Etiology.—The bacteriologic cause of bronchopneumonia is not a specific entity. There are a number of micro-organisms which may cause the disease, and in over 60 per cent, of the cases there is a mixed infection. This is true even in the primary cases. The Diplococcus pneu- moniae (Frankel) is the organism most frequently present, but it is found in pure culture only about one-fourth as often as in combination with other organisms. In children less than three years of age Wollstein1 found the incidence of fixed types of pneumococcus much less than in adults, whereas Type IV occurred far more frequently. Fortunately, Type III is very rare. The mortality figures for the types approximate the figures for adults. The streptococcus comes next in order of fre- quency—three times more often in combination than in pure culture. Staphylococcus aureus may be present alone, but is far oftener found with the pneumococcus or the streptococcus. The bacillus of Friedlander, either in pure culture or in mixed infection, is a rare cause of broncho- pneumonia in children. Since bronchopneumonia may be secondary to a variety of diseases, the causative organism of the primary condition in a given case may be 1 New York State Journal of Medicine, vol. 23, No. 4, 1923. 369 PNEUMONIA found in the pulmonary lesion. Thus Bacillus diphtherise, B. influenzae, the Bordet-Gengou bacillus of pertussis, B. typhosus, B. pestis, B. an- thracis, B. pyoeyaneus, or the meningococcus may be found associated with one or more of the pyogenic cocci. Bacillus coli communis is a pos- sible though very rare factor in this disease. Pathology.—Ordinarily the process begins as an inflammation of the terminal bronchioles, “capillary bronchitis,” and by extension involves the air-vesicles and takes on the character of a true pneumonia. Broncho- pneumonia is, as a rule, bilateral, and only exceptionally involves a single lobe of one lung. The disease usually produces inflammation of the pleura. The affected lung acquires increased weight and the regions most involved acquire a firmer consistence and a deeper red or a grayer color than normal, depending on the stage of the inflammation, which at the outset occasions intense congestion without much leukocytic exudation. On section, the affected portions typically appear mottled, owing to the contrast apparent between the masses of solid and aerated lobules. Microscopic examination reveals an inflammation of the bronchioles and of the walls of the air-vesicles immediately surrounding. There is not only an exudate in the air-vesicles but also an interstitial exu- date. In the bronchopneumonic exudate the cells are more predomi- nantly mononuclear, and the amount of fibrin is less than in the exu- date of lobar pneumonia. The lesions are distributed throughout the lungs in patches, but show a tendency to become conglomerate as the disease advances. When the inflammation subsides the exudate is re- moved, as at the termination of lobar pneumonia by mechanical proc- esses and by the agency of autolysis. The interstitial infiltration char- acteristic of bronchopneumonia is responsible for the occurence of its more important sequel®, none of which commonly follow lobar pneu- monia. These are chronic bronchitis, spasmodic asthma, emphysema, and chronic interstitial pneumonia. Pleurisy, when it occurs in children, irrespective of the character of complicating pneumonia, is of a pro- ductive type. Physical Signs.—Auscultation.—The signs elicited by auscultation depend upon the stage of the disease and the degree of lung involvement. The respiratory murmur may be weakened over certain areas, or it may be scarcely discernible. Usually an involved area will be found to shade off gradually to the normal. There may be several of these areas. Areas of localized fine mucous rales are very suggestive of broncho- pneumonia. The fine crepitant rale is often heard over the consolidated area. In cases in which there is a considerable distribution of the pneumonic process there will be a wide distribution of rales, with sibilant and fine, moist, mucous rales predominating. The rales are only evenly distributed in cases of the acute congestive type. In these cases they are heard both on inspiration and on expiration, and are of a very fine, crepitant quality. Percussion.—In the very acute cases in which the engorgement inter- feres with the entrance of air into the lungs extra resonance or tympanitic dulness may be found. In other cases the percussion-note serves as an indication of the degree and extent of lung involvement. The signs vary from normal to those of complete dulness. 370 THE PRACTICE OF PEDIATRICS Palpation.—Whatever may be elicted by palpation is better dem- onstrated by auscultation and percussion. Symptoms.—The symptoms are most variable, depending upon the age of the patient, the severity of the infection, the extent of lung in- volved, and the associated illness and complications. In nearly all cases in which the process in the lungs is active there are three symptoms which rarely fail to be present: accelerated respira- tion, fever, and cough. The symptoms are only exceptionally urgent at the onset. Usually there is bronchitis for a few days, without high fever or rapidity of the respiration. Then, apparently on the eve of improvement, the temperature ranges higher, the respirations per min- ute increase, and the child shows prostration. Fi g. 72.—Bilateral bronchopneumonia involving chiefly the lower right lung. (Children’s Medical Division, Bellevue Hospital.) Examination of the lungs at this time may reveal localized fine rales, usually posteriorly in one or both lungs. As the urgency of the symp- toms increases the temperature ranges from 101° to 104° F., subject to considerable variations, and in the event of recovery reaches the normal by lysis. The respiration rate is from 40 to 60. The pulse-rate is rarely under 140. The usual range is from 140 to 160. Upon the appearance of acute symptoms the chest signs become more marked. Localized areas of fine rales appear in different portions. There are also areas in which the respiratory murmur is very weak. Consolidation usually develops suffi- ciently to produce bronchophony and bronchial breathing. Duration.—The duration of a case of this type terminating in recovery is rarely less than three weeks. Often a much longer time elapses before the chest will be free. In the fatal cases there is an increase in the volume PNEUMONIA 371 of lung involved, shown by the physical signs. The heart action be- comes feeble, and death takes place from exhaustion or supervening com- plication. Special Types of Bronchopneumonia.—In the description of a dis- ease with as wide possibilities as bronchopneumonia a large number of types could be enumerated which would add confusion to the subject. As in most diseases due to infections, death may take place very early or the infection may be so mild as to pass unrecognized. When we take into consideration the age of the patient, the varieties of micro-organisms that may be operative, and the amount of lung tissue that may be in- volved, we can readily appreciate the occurrence of many and varied manifestations. Among these possibilities there is one feature that should be emphasized. Consolidation of the lung is not necessary for a correct diagnosis of pneumonia. Elevation of the temperature, respiration over Fig. 73.—Temperature chart. Bronchopneumonia. 40, dilatation of the ahe nasi, and cough, together with mucous rales, usually definitely localized, are sufficient for a positive diagnosis. Cases of the More Active Type.—Bronchopneumonia may be so severe as to be fatal in a few hours. At the New York Infant Asylum several such cases were observed, which later came to autopsy. The condition is usually diagnosed as acute capillary bronchitis. In such patients the onset is sudden, with high fever, 103° to 106° F., rapid, labored respiration, 60 to 80, rapid pulse, 160 to 180, and cyanosis. There is immediately marked prostration. The child is toxic and rapidly be- comes unconscious. Auscultation detects a very marked increase in respiratory murmur, and a few fine rales. The evidence indicates a sudden invasion of pneumococci of a virulent type. 372 THE PRACTICE OF PEDIATRICS Doubtless cases of this type are never correctly diagnosed. In two notable instances a positive diagnosis could not have been made but for the autopsy. On account of the urgency of the symptoms and the cerebral manifestations of stupor and sometimes convulsions, the cases are looked upon as those of cerebrospinal meningitis, malignant scarlet fever, suppressed measles, or acute toxemia of intestinal origin. Postmortem examination shows an intense pulmonary congestion. A free incision in the lung removed immediately after death will be fol- lowed by a profuse outflow of dark blood. Excepting the congestion and the presence of the pneumococcus, there are few findings to indicate the nature of the disease, the process having been too active and too rapidly fatal for the development of the lesions. Illustrative Case.—Several years ago the writer was called to perform an autopsy on a six-year-old boy who had died after a two days’ illness, the nature of which could not be agreed upon by the medical attendants, none of whom had suspected pneu- monia. The autopsy findings were those of an acute pneumonia with intense pul- monary engorgement and with right heart dilatation, which corresponded to the clinical history. Cases of this nature represent the extreme possibilities of pneumococcus infection. There are other cases in which the symptoms are urgent, but less pronounced. The onset is sudden, with high fever, 103° to 105° F. The respiration is rapid, 40 to 60. Rarely there is a convulsion. Vomiting is usually present as an early symptom and occurs but once. Except in the nature of the onset, the course in these cases does not vary materially from the usual type first described. The temperature range, physical signs, duration, and prognosis are much the same as in the cases of gradual onset. Bronchopneumonia Following Other Diseases.—When bronchopneu- monia follows pertussis, influenza, measles, or diphtheria it shows no variations from its usual course, but finds a lessened resistance because of what has gone before. The prognosis is therefore correspondingly less favorable, the disease being particularly fatal with or after pertussis, measles, and diphtheria. Complications.—Among the complications, otitis is probably the most frequent. Empyema occurs in a small proportion of the cases. The same is true of pericarditis, meningitis, arthritis, and nephritis. Emphysema is always present to a slight degree, and except in rare instances is demonstrable at autopsy in fatal cases in young subjects. If the illness has been long, with considerable lung involvement, the emphysema may be very extensive. Differential Diagnosis.—Bronchopneumonia is to be differentiated from acute bronchitis and lobar pneumonia. When the respiration is persistently above 40 per minute and the temperature persistently above 102° F., uncomplicated bronchitis does not exist, and pneumonic involve- ment of the lung is highly probable. If there is an associated bronchial spasm increasing the respiration, a differential diagnosis is more difficult and sometimes impossible, as pneumonia may exist with a low temperature range. PNEUMONIA 373 In lobar pneumonia the well-defined consolidated area in the lung, the absence of bronchial catarrh, and the usually persistent high tem- perature (Fig. 71) are sufficient to establish the type of the infection. The x-ray is invaluable in arriving at accurate diagnosis. The age of the patient may be of assistance. Lobar pneumonia is least common under two years of age, and the great majority of the cases of bronchopneumonia occur before this period. Prognosis.—Bronchopneumonia is a disease of high mortality. In children’s hospitals and institutions a considerable portion of the total mortality is due to bronchopneumonia. It is safe to say that from 25 to 50 per cent, of such hospital cases are fatal. This, of course, includes all cases of bronchopneumonia, those complicating whooping-cough, measles, scarlet fever, and diphtheria, as well as the terminal cases that occur late with many other ailments. The age and previous condition of the patient have a decided influence upon the mortality. The younger and feebler the patient, the less is the chance for recovery. Rachitis, malnutrition, and marasmus are indirectly accountable for many deaths. Treatment.—In treating bronchopneumonia it must be our effort to preserve every strength unit which the child possesses. An immense amount of vitality is wasted because of irritability, restlessness, and loss of sleep. One of the first duties in a given case is not to give this or that drug or use this or that local application, but to make the child comfort- able. The Sick-room.—The value of a constant supply of fresh air is too little appreciated. In every case there should be a direct communica- tion between the sick-room and the open air throughout the attack. Various means of ventilation have been devised, of which the window- board (p. 26) is the most effective, as it separates the sash and allows the free entrance of a current of air which is directed upward. If plenty of fresh air at a proper temperature were available during the early part of the illness there would be much less use for tanks of oxygen later. An absolute necessity in a sick-room is a thermometer. In pneu- monia cases it should never register above 70° F. There is a marked tendency to coddle, to wrap, and to overclothe the patient. Even during the winter, absolutely nothing more is required than a medium-weight flannel shirt, a band, if one is ordinarily worn, and the usual night-dress. The oiled-silk jacket is cumbersome, cannot be kept clean, and over- heats the patient. An infant with catarrhal pneumonia, heavily clad, in an unventilated, overheated room, and in close contact with an adult body, is tremendously handicapped. There is but one place for a sick infant, and that is in his own roomy crib. Diet.—In every illness with fever the digestive capacity is consider- ably reduced. If the usual milk diet is continued a gastro-enteric infec- tion may be added as a serious complication to the existing disease. For the breast-fed child a drink of water should be ordered just before the nursings and in the intervals between them. The nursing hours should be the same as in health, but the time allowed for each nursing should be reduced from one-third to one-half. For the bottle fed the milk strength should be reduced from one-third to one-half by dilution with water, 374 THE PRACTICE OF PEDIATRICS the quantity remaining the same. Children from two to four years of age should be restricted to a diet of diluted milk, gruels, and broths. Bowels.—Normal bowel function is more necessary for the sick than for the well. There should be at least one stool in twenty-four hours. General Treatment.—Having placed the child under the best dietetic and hygienic conditions, we are in a position to use medication to a much better advantage. But in its use, and in performing the various offices for the patient, it must be our effort to disturb him as little as possible. In our anxiety to do, we are very liable to overdo, with disastrous results. If a well child were given syrup expectorants, stimulants, baths, and local applications, something being done for him every hour or two in the twenty-four, he would have to be strong to withstand the treatment. We should treat our ill with still greater consideration. The intervals between which the child is to be disturbed at night should be made as long as possible by giving food, medicine, and local treatment at one time. When possible, we always endeavor to make the interval at least three hours. Steam Inhalations.—Among the distinctly remedial measures steam in- halations with creosote deserve an important place. The patient is placed « in the crib, which is covered and draped with sheets so as to make a fairly tight inclosed space. The apparatus necessary is an ordinary croup ket- tle. Ten drops of creosote added to 1 quart of water are poured into the kettle. The nozzle of the kettle is introduced between the sheets at a safe distance from the child’s face and hands, the steaming being carried on for thirty minutes every three hours. The sheets should be parted slightly about every ten minutes to allow a renewal of the air. The inhalations are to be given whether the patient is asleep or awake. As he improves, they may be given less frequently until normal respira- tions and the chest signs tell us this treatment is no longer required. Counterirritants.—The application of counterritants to the skin over the thorax is of great service in cases in which there is much bronchial catarrh. This includes, of course, most cases. In order that a counter- irritant may be of service a distinct red blush must be produced on the skin. Turpentine diluted with oil—one-third turpentine and two-thirds oil—when briskly rubbed on the parts for a few minutes produces a fairly satisfactory counterirritation. An objection to its use is the rare occurrence of albuminuria in a patient abnormally susceptible to this drug. The old- fashioned home-made mustard plaster has also served well. Written directions should always be given for the preparation of the plaster, and the boundaries of the area of the skin to be covered should be outlined with a pencil on the skin surface. If the nurse or mother is told merely to put a mustard plaster on the chest, a plaster the size of a man’s hand will usually be placed somewhere between the umbilicus and the chin. For the first two or three applications 1 part of mustard to 2 parts of flour is used. This is moistened with warm water and made of the consistence of a rather thin paste, which is then spread upon cheese-cloth, old muslin, or linen, cut to the desired size. The plaster is readily held in position by a bandage or any thin material extending around the chest. When the skin is well reddened—usually within from five to fifteen minutes—the plaster is removed and vaselin or sweet oil is applied. PNEUMONIA 375 One should never use a plaster oftener than once in six hours, and then only in the severest cases. Ordinarily, two or three applications in twenty- four hours are sufficient. If the plasters are continued for several days, in order to avoid blistering it will be necessary to make them much weaker after a day or two—1 part of mustard to 5 or 10 of flour. Counterirrita- tion is particularly effective when used at the commencement of an attack. Mustard Baths.—In cases of sudden onset with high fever, rapid breathing, and cold extremities, a mustard bath—1 tablespoonful of mustard to 6 gallons of water at 110° F.—will often furnish marked relief from the immediate symptoms. The duration of the bath should be from one to three minutes, in which time the skin should be subjected to active manipulation by hand rubbing. The bath may be repeated at six-hour intervals. This type of bronchopneumonia is usually very rapid in its develop- ment, the child being relieved or dead within thirty-six to forty-eight hours. By “relieved” we do not mean that recovery has occurred, but that the acute, urgent symptoms have subsided. In our opinion only these rapid cases should be considered primary. Autopsies on such subjects show a general congestion of the internal organs, with intense congestion of the lungs. Drugs.—The internal medication is, to a large extent, symptomatic. It is particularly necessary that, in our endeavors to assist the patient, we do nothing to cause harm, for we are treating a disease in which resist- ance counts for everything. In illness with fever, with the accompanying nervous exhaustion, the stomach is most easily disturbed, the child is then not properly nourished, and his powers of resistance are markedly diminished. Expectorants must be given with care, and are better prescribed in the form of tablets or powders. The use of heavy syrups of wild cherry, tolu, etc., with large doses of the ammonium salts, only adds to the burden of the patient. For a child one year of age with bronchopneumonia 1/100 grain of tartar emetic and 1/40 grain of ipecac answer well as an expectorant. If the cough is very severe and persistent, \ grain of Dover’s powder in tablet form with sugar-of-milk, dissolved in at least 2 tea- spoonfuls of water, may be given, preferably after feeding, not oftener than once in two hours. The ammonium salts so generally used in catar- rhal pneumonia for routine treatment are badly borne by the stomach. Ammonium muriate is of some value during resolution, but to a child two years old it should not be given in larger doses than \ grain well diluted at two-hour intervals because of its irritant effect on the stomach. In the event of high fever and great restlessness, which are not affected by sponging, and where, for any reason, rational bathing is impossible, a combination of caffein, Dover’s powder, and phenacetin may be used. To a child one year of age may be given \ grain of caffein, grain of Dover’s powder, and 1| grains of phenacetin at four-hour intervals. In giving Dover’s powder it is well to watch the bowels, as constipation often follows its use. A heart stimulant should never be given simply because a child has pneumonia or diphtheria or scarlet fever, but it should be given in pneu- monia or diphtheria or scarlet fever as soon as the heart needs assistance. 376 THE PRACTICE OF PEDIATRICS Briefly, there are two conditions to guide us—a very rapid pulse and a soft, not rapid, pulse, with a tendency to irregularity. As a general rule one may say that a heart which is beating at the rate of 150 a minute during quiet or sleep, and which is not strengthened by sponging or packs, needs assistance. The drug which is here indicated is digitalis, which acts as a direct stimulant to the heart muscle. The pulse, by its use, is made stronger, fuller, and less rapid. When the heart’s action shows a tendency to irregularity, with a soft, easily compressible pulse, then strychnin is the remedy. Caffein sodiosalicylate in §-grain doses every two hours is also of much use in such a condition. To a child one year of age 2 drops of tincture of digitalis in water may be given every three hours, or 1/300 grain of strychnin every three hours, to be increased to 1 /200 or even to 1/100 grain every three hours for a few doses, if the case is carefully watched for symptoms of strychnin-poisoning. Digitalis and strychnin possess advantages over all other stimulants in that they do their work and have no unpleasant effect on the stomach, as is the case with alcohol, digitalis, and the ammonium preparations. If the condition is very urgent, digitalis and strychnin may be used in combination. Alcohol in the form of whisky or brandy is very rarely of great service in catarrhal pneumonia. It may stimulate the heart, but its prolonged use greatly upsets the stomach. It should be withheld until late in the disease, when other means of stimulation fail. Then, given in large amounts, it may be the means of saving the patient; \ dram of whisky or brandy, well diluted, may be given every hour or every two hours to a child one year of age. However, the cases of catarrhal pneumonia actually saved by the use of alcohol are few indeed. Nitroglycerin, 1/300 grain every three hours for a child one year of age, is of service in cases where there is marked cyanosis with cold extremities. Its use should be discontinued as soon as improvement in this respect is noticed. The one unpleasant feature observed from its administration is its tendency to produce head- ache and marked restlessness. Hypodermic Medication.—In all urgent cases in which collapse is threatened, or when oral medication does not give results desired, one may employ the hypodermic, using the same dosage given by the mouth. Camphor may be given in 2-grain doses and repeated hourly if neces- sary. Digitalin, in dosage of 1/200 grain, may be given and repeated in three or [four hours. For urgent collapse, camphor, and 1:1000 solu- tion of adrenalin in dosage of 3 to 5 minims, are our best stimulants. Baths.—A sponge-bath at 95° F. for cleansing purposes may be given daily. Pyrexia.—What is to be our guide in dealing with the pyrexia? At what degree of temperature are we to interfere? This depends to a great extent upon what is behind the fever and the effect of the fever upon the individual patient. If a child has a high fever and is more comfortable when it is reduced, if he will digest his food better and sleep better, our duty is to reduce temperature. Further, by reducing it we lessen the work of the heart, saving many beats per minute. Usually, when the rectal temperature has a tendency to run above 104° F., interference is of ad- vantage, and the best means at our command is the use of local applica- tions of water in the form of sponge-baths or packs. If the temperature PNEUMONIA 377 is easily controlled, a sponge-bath will answer our purpose. Either salt or alcohol may be added to the water. Ordinarily, 2 teaspoonfuls of salt to 1 quart of water, or 1 part of alcohol to 3 parts of water, is ample. Cold water thus used serves two purposes—it acts as a sedative and it reduces the fever. Cold sponging, while not as effectual as a bath or a pack, possesses the advantage of being applicable even in the hands of the most unskilled. For sponging, the child should be stripped and covered with a flannel blanket, the sponging being done under the blanket. In order not to antagonize or frighten him, it is best to begin with the water at 95° F. and gradually to reduce the temperature to 70° or 75° F. by the addition of ice or cold water. The sponging may be continued from ten to twenty minutes, and should not be repeated at shorter intervals than ninety minutes. After the sponging is completed the skin should be rubbed briskly for a few minutes with a dry towel. If the temperature is not readily controlled in this way, it is best to use other means, as too fre- quent sponging exhausts the patient. As a means of controlling the temperature in children the tub-bath has not proved successful in our hands. The exposure, the fright, and the * necessary shortness of the bath render it very unsatisfactory. By far the best means at our command for controlling a continued high fever is the cool pack (p. 841). Properly applied, it is without the slightest danger. A large bath-towel or any thick absorbent material may be used, slits being cut in one end of the towel through which the arms may pass. The towel should be folded over the body, and should extend from the neck to the middle of the thighs, the arms and the legs from the knees down remaining free. A hot-water bag, carefully guarded, should be placed at the feet. The towel is moistened with water at 95° F. It is well to make the pack warm at first, so that the child will not be frightened, as shock will thus be avoided. In two or three minutes the towel is moistened with water at 85° F., then at 80° F. When 80° F. is reached it is best not to make the water any colder for half an hour, at the expiration of which time the temperature of the patient should be taken. If, in the beginning, it is 105° F. and at the expiration of the half- hour shows slight or no reduction, the temperature of the pack may be reduced to 70° or even to 60° F. by the addition of cold water or ice, with- out removing the child, who is turned from side to side so that all parts of the enveloping towel may be moistened with cool water. During the first hours in the pack the temperature should be taken every half-hour, and when it is reduced to 102° F. the child should be removed and wrapped in a warm blanket. In cases of sudden and persistent high fever the child may be kept in the pack continuously. We aim to keep the tempera- ture between 102.5° and 103.5° F. A fresh towel should be applied every three hours. An ice-bag should be kept at the head, a hot-water bag at the feet, and the patient should be covered with a flannel blanket of medium weight. The degree of cold necessary to control the fever in a given case will soon be learned. The writer kept in a pack for seventy-two hours a four-year-old boy ill with lobar pneumonia. In this case a pack at 70° F. was necessary to keep the temperature at 104° F. or slightly lower. 378 THE PRACTICE OF PEDIATRICS Oxygen is of immense service in very severe cases with much lung involvement. It may be given for one or two minutes out of every seven or ten, or continuously with the funnel kept a few inches from the child’s face. As often given, for one or two minutes every half-hour, it is of little or no service. Transfusion is of value under the exceptional conditions which may call for its employment in lobar pneumonia (p. 367). INTERSTITIAL PNEUMONIA AND BRONCHIECTASIS Interstitial pneumonia occurs in two types of cases. After bron- chopneumonia the interstitial variety represents an unresolved pneu- monia, and usually means that the individual has had more than one attack. The great majority of such cases are seen in ill-conditioned infants in hospitals and institutional homes. Rarely is this type seen in older children. The second type represents the cases of unresolved pneumonia, usually lobar pneumonia, which have been complicated by empyema, and in which the empyema has not been recognized or has been improperly treated. Pathology.—Chronic interstitial pneumonia is a productive inflam- mation characterized by thickening of the connective-tissue framework of the lung. This disease follows one or more attacks of bronchopneu- monia or may accompany a chronic empyema. The process may involve one or more lobes of the lung or only a portion of one lobe. The involved lung is usually adherent to the chest wall by very dense fibrous adhesions, and is smaller than normal, firm, and grayish in color. On section, the pleura and connective-tissue septa are found to be greatly thickened. The bronchi are often dilated, and may be the seat of purulent bronchitis. Microscopic examination shows that the interlobular septa, the walls of the bronchi and blood-vessels, and the alveolar walls are thickened with connective tissue. As a consequence some alveoli may be obliterated. Compensatory emphysema is often present in a portion of the un- affected lung. Symptoms .—Not half the symptoms described by writers exist. The principal manifestation is afforded by the condition of the patient, who is anemic, emaciated, and fails to thrive, or improves but slowly even under the best surroundings. There may be cough and, rarely, fever. The respiration is acceler- ated upon exertion, but otherwise shows no change. If there is an as- sociated bronchiectasis, in older patients there will be mucopurulent or purulent expectoration. Illustrative Case.—A boy for several years expelled free expectoration about once a day. There was an interstitial pneumonia involving the lower half of the right lung, which was the seat of one or more bronchiectatic cavities. The pus evidently collected periodically and filled the cavity, then producing cough and emptying of the cavity. Diagnosis.—Inspection.—There may be extensive retraction of the chest wall or none at all, depending on the age of the patient. In infants under eighteen months there is rarely such retraction. INTERSTITIAL PNEUMONIA AND BRONCHIECTASIS 379 Upon forced inspiration, as in crying, it will be noticed that the chest wall over the involved lung area fails to take part in the normal respiratory excursion. Older children exhibit varying degrees of retraction, usually associated with spinal curvature. Auscultation.—The respiratory signs are subject to wide variations. Thus in one case there may be bronchial breathing over one diseased area and entire absence of the respiratory murmur over another area. Between these extremes in the same case there may be a variety of abnormal respiratory sounds. Over the uninvolved lung the respiratory murmur undergoes pronounced exaggeration. If there is a consid- erable bronchiectasis, signs of a cavity will be indicated by amphoric breathing. Percussion invariably shows localized dulness over the diseased por- tion of the lung. One may find all shades of dulness to flatness. Over the free portion of the lung hyperresonance will be found because of the emphysema, which is always present in slight or moderate degree. x-Ray examinations are of great value, if repeated over a considerable period of time, in showing recession or extension of the process. Differential Diagnosis.—The question that always arises in these cases relates to the possibility of tuberculosis. A considerable number, particularly under two years, do develop tuberculosis. An examination of the sputum and the intradermal tuberculin test should invariably be made. In cases in young infants a positive tuberculin reaction supplies reliable corroborative evidence. Repeated examination of the bronchial secretions (p. 396) will reveal the tubercle bacillus if it is present. When the lesions are tuberculous in older children examination of the sputum quickly determines the diagnosis. Prognosis.—The prognosis in an infant is very unfavorable. If tuber- culosis does not develop, intercurrent disease, such as the intestinal disease of summer, whooping-cough, measles, or acute pneumonia, will very likely terminate the case. Recovery is not impossible, however, and infants have been observed to make almost complete recoveries after the process had existed for months. In one case the child’s chest did not begin to “clear” until after the third month. In recovery cases the interstitial change cannot have been at all extensive. In an older child after the sixth year a favorable prognosis as regards life is the rule. Whether the case follows bronchopneumonia or pneu- monia with empyema, even with the best results, there will be left a more or less crippled lung, which does not necessarily compromise the later well-being of the patient. Such patients, however, are more liable to tuberculous infection, and this possibility is always to be taken into con- sideration in their management. Bronchiectasis is present in a considerable number of cases of intersti- tial pneumonia, both in the young and older children, consisting of dilata- tion of the bronchi, usually sacculated or cylindric in form. Illustrative Case.—The lungs of a child eighteen months of age who died from bronchopneumonia of three months’ duration, with terminal sepsis, presented several small cylindric dilatations. One of these, with a capacity of 6 drams, was found in the right lung. This case is similar to many seen at autopsy. 380 THE PRACTICE OF PEDIATRICS In young infants bronchiectasis may be very difficult of demonstra- tion. In the cases of older patients the expectoration of pus in a chronic pneumonia is very suggestive, and in such instances physical examination may reveal amphoric breathing and other signs of cavity. Dilatation of a bronchus may be cylindric, sacculated, or spindle shaped. It is accompanied either by atrophy or by hypertrophy of the mucosa and of the entire bronchial wall. Dilated bronchi contain thick mucous or purulent secretion, often in very large amount. The secretion may be blood-stained, due to rupture of some of the very numerous blood-vessels in the hypertrophied mucosa. Pressure of the dilated bronchi often causes collapse of the pulmonary alveoli surrounding them. The walls of neighboring bronchi may fuse, forming larger cavities. Treatment.—The treatment of interstitial pneumonia is not par- ticularly brilliant in results. There is always the hope that the inter- stitial process dependent on cicatricial change is not extensive, for this feature determines in no little degree the outcome of the case. When resolution takes place, it occurs always from the periphery toward the center of the diseased part. The involved area becomes smaller and smaller and disappears, or, more frequently, as the ultimate outcome, an area of weakly vesicular breathing remains to mark the site where the disease was most active. Little can be accomplished by the use of drugs except to improve the nutrition of the patient. Children with this unfortunate pulmo- nary disease should take up their permanent residence in a dry climate, like that of Colorado or New Mexico. A visit of a few months or a year is of but little service. The writer used the iodids and the bichlorid of mercury for months without any appreciable improvement in two of these patients who could not be removed from town. The citrate of iron and quinin, 1 grain in a dram of sherry wine, makes a good appetizer, and may be given in \ glass of water after meals. Its use can with ad- vantage be alternated with that of the syrup of the hvpophosphites (Gardner), 1 to 3 drams being given daily in | glass of water after meals. Cod-liver oil may be used with advantage for ten days out of the month, but its continued use is contraindicated, as it is apt to inter- fere with digestion. Illustrative Case.—In one of the cases above referred to the iron was given for ten days and the oil for ten days, after which the procedure was steadily repeated. The patient continued to look well, gained in weight, and remained under treatment until he took up an occupation and passed from observation. The condition of the lung had remained unchanged, the only active manifestation of the disease being the ex- pectoration of a considerable amount of non-tuberculous pus every morning on rising. Whenever periodic accumulations of pus are demonstrated the child should practice leaning over a chair at least twice daily with head and trunk inverted to facilitate evacuation of the cavity. Frequently after such a maneuver with its attendant coughing up of expectoration there will be localized hyperresonance and amphoric breathing where a few minutes previously had been dulness and diminished breath sounds. It is desirable that the cavity should be distended by accumulation of secre- tion as little of the time as possible. Infants and children with bronchiectasis who cannot be removed PNEUMOTHORAX 381 to a favorable climate should have the advantages of outdoor life, and older children should have as much active exercise as is possible with- out fatigue. The diet and general management are the same as for pul- monary tuberculosis (p. 397). In a considerable number of cases under observation at Bellevue Hospital creosote has been continuously adminis- tered, with apparently good effect. Gymnastic Therapeutics.—For the purpose of expansion of the lung with the hope of curing the chest deformity gymnastic exercises are of the greatest value. Following the aspiration of foreign material into the lower air-passages pneumonia may rapidly develop. In the case of aspiration of a single for- eign body such as a seed or kernel the process may be definitely localized. When the insufflation takes the form of aspiration of vomitus under an- esthesia or is produced by direct mechanical action, such as may occur when blood or secretions are forced downward under anesthesia ad- ministered intranasally or intratracheally by a tube, the pneumonia may be disseminated. This form of pneumonia is the type probably most frequently developing in infants or in children with low vitality who undergo cleft-palate repair, retropharyngeal abscess incision, and tonsillectomy under deep anesthesia. The possibility of the occurrence of pneumonia of this type should never be overlooked by operators or anesthetists. The accidental aspiration of stearate of zinc by infants is a well- established cause of asphyxia and lung irritation with lesions which may give rise to areas of consolidation and give the physical signs and symptoms of bronchopneumonia even though cultures from lung tissue taken postmortem may be found sterile.1 The loosely capped talcum powder box should, therefore, be regarded as a dangerous toy. INSUFFLATION PNEUMONIA Hypostatic pneumonia is a form of lobular pneumonia which de- velops in fatal cases in the most dependent portions of the lungs, these portions having become very hyperemic as the result of weakness of the heart and respiration in patients who are severely ill. The affected pulmonary tissue is dark red in color, very firm, and airless. On section, the cut surface is red and very moist, exuding blood freely. Microscopically, the capillaries and veins are distended with blood, and the alveoli are filled with red blood-cells, leukocytes, and desquamated epithelium. The bronchi are usually in good condition. The extent of the consolidation varies. While it usually occupies only a superficial strip along the posterior border and base of the lungs, fully half of the lower lobes may be involved. HYPOSTATIC PNEUMONIA Air in the pleural cavity may be due to tuberculosis or to trauma (usually through exploratory puncture) causing perforation of the lung. We have seen only one or two undoubted cases of this nature. Pneu- PNEUMOTHORAX 1Heiman and Aschner, Amer. Jour. Dis. Child., June, 1922. 382 THE PRACTICE OF PEDIATRICS mothorax also may occur in empyema. By far the most frequent cause in children is the formation, by a tuberculous cavity, of a communication between a bronchus and the pleural cavity. Artificial pneumothorax is employed as a means of treatment in selected cases of tuberculosis. Symptoms .—In the tuberculous cases of pneumothorax the symp- toms comprise very sudden onset of urgent collapse, urgent dyspnea, cyanosis, and rapid, feeble pulse. In cases due to trauma the symptoms may be urgent or scarcely noticeable, depending upon the extent of the lesion. In a case which developed after exploratory puncture, only a moderate amount of air entered the pleural cavity and no inconvenience was occasioned. Physical Signs.—The physical signs are determined largely by the amount of air entering the pleural cavity. They may include simply Fig. 74.—Pneumothorax resulting from traumatic rupture of the right lung which appears as a solid mass close to the midline. (Children’s Medical Division, Bellevue Hospital.) hyperresonance and absence of respiratory sounds. In cases of tuber- culous origin there is usually a sudden inrush of air, with resulting im- mobility of the affected side and enlargement of that side of the thorax. There is marked hyperresonance, and an absence of fremitus. In cases in which the amount of air is not excessive there will be tympanitic dul- ness. Displacement of the heart by the accumulated air under pressure may be demonstrated in extreme cases. Auscultation reveals very weak breath sounds or entire absence of the same. The coin test is very diagnostic. A coin is placed on the chest, either anteriorly or posteriorly, and tapped with another coin by an assistant, while the ear of the examiner is placed on the opposite aspect EMPHYSEMA 383 of the same half of the chest. The sharp metallic sound conveyed, in comparison with the absence of sound over the opposite lung, furnishes a demonstration to students that will never be forgotten. If there is fluid in the pleural cavity, splashing, metallic, tinkling sounds may be heard. Diagnosis.—A rare condition in which the diagnosis of pneumothorax has wrongly been made is congenital diaphragmatic hernia. Tympanitic coils of intestine in the thoracic cavity of a child ill with bronchitis or pneumonia strongly suggests pneumothorax. Radiographs not only of the lungs but also the gastro-intestinal tract are essential to give a satis- factory demonstration in such an instance. Prognosis.—The prognosis depends upon the cause of the air in the pleural cavity. The tuberculous cases are rapidly fatal. After trauma the recovery depends upon the nature of the injury. In the cases fol- lowing exploratory puncture recovery without treatment is common. Treatment.—In complicating empyema the fluid should be removed by surgical procedures. If there is marked displacement of the heart and considerable intrathoracic pressure, tapping the chest with a needle, and allowing an escape of the air, may be of value, particularly if a valve- like action at the aperture in the lung has induced extreme compression of air in the pleural cavity. EMPHYSEMA Emphysema is a secondary disease. There are few autopsies on children dying from pulmonary disorders in which it is not found pres- ent in greater or less degree. It is always present in considerable amount in cases of interstitial pneumonia, and in this association the emphysema is compensatory in character. It is found with whooping-cough, broncho- pneumonia, habitual spasmodic bronchitis, and true asthma. Pathology.—Emphysema is most frequently found in a pronounced degree in the upper lobes, especially at the anterior borders and the apices. The air-vesicles are persistently dilated, and on inspection, to the unaided eye, present a picture of innumerable pin-point air-bubbles. When the septa give way the vesicles enlarge so that blebs of various size occur. The condition rarely becomes interlobular. Symptoms.—In many cases there is no special manifestation, and the fact that emphysema exists is discovered only at the autopsy. This is particularly common in compensating cases in which there is a good deal of lung involvement, as in interstitial pneumonia or in prolonged bronchopneumonia. When there has been repeated spasmodic bronchitis or true asthma, there is shortness of the breath, with rapid breathing, and the thoracic wall presents a fixed appearance owing to the diminished or impercep- tible respiratory excursion. The so-called barrel-shaped chest is seen in children, but is of com- paratively infrequent occurrence. The child usually has a dry cough, is incapable of the usual exer- tions of early life, and readily becomes cyanosed through air-hunger. Physical Signs.—Percussion.—There is increased resonance on per- cussion, general in distribution, but most marked over the upper lobes 384 THE PRACTICE OF PEDIATRICS in front. When the emphysema is not excessive tympanitic dulness may be elicited. The area of cardiac dulness may be much smaller than normal or entirely obliterated. Auscultation.—Upon auscultation the respiratory murmur is found to be feeble, and expiration is noticeably prolonged and longer than inspiration. Squeaking, small, dry rales are usually heard in children because of the almost invariable association of bronchitis. The rales are heard both on inspiration and on expiration. The respiratory sounds have been aptly described as wheezing in character. Prognosis.—The prognosis in general emphysema is unfavorable. The attacks of recurrent asthma or recurrent spasmodic bronchitis, which induce the process, continue, and the condition becomes most pitiable. Dilatation of the right heart ultimately occurs. Cardiac failure and acute pulmonary disease are the usual terminal affections. Treatment.—The management is that of the associated condition. SUBCUTANEOUS EMPHYSEMA WITH EMPHYSEMA OF THE MEDIASTINUM This is a rare condition in children. Before the use of intubation, when tracheotomy was in vogue, many more cases were seen than now. Other causes may be pertussis, tuberculosis, or trauma to the lung. The first site affected is typically the mediastinum, whence the emphysema extends to the subcutaneous tissues and is particularly apt to appear above the clavicles, where it produces a cushion-like effect. In one case the emphy- sema extended from this point downward over the thorax, and upward, involving the entire neck. Prognosis.—Cases following operative procedures and trauma may undergo recovery. When the condition is a complication of pulmonary disease the outlook is very unfavorable. PRIMARY PLEURISY Acute, primary pleurisy is a very rare condition in children. Of 5 patients with this condition, under nine years of age, 1 was eight; 1, seven; 1, four years of age; 1, two and a half years, and 1, only fifteen months old. Pathology.—In these cases there is inflammation of the pleura with exudate, but usually not sufficient inflammation to produce an appre- ciable exudate. Symptoms.—The onset of the disease is practically the same as in adults. There is localized pain—the so-called “stitch in the side”; the respiration is rapid—40 to 60 to the minute—and shallow; the skin is dry and hot; the cough is teasing, and, on account of the pain which it causes, is partially suppressed by the patient. Fever is present, usually ranging from 102° to 105° F. The pulse is rapid—120 to 150 to the minute. In two cases the pleuritic inflammation was followed by effusion. The fluid in both cases was sterile. So far as we could learn there was no associated rheumatism in any of the cases. Treatment.—The treatment which proved successful in the 5 cases cited was rest in bed. The patients were given a reduced diet of milk, SECONDARY PLEURISY 385 broths, and gruel. The fever was not of a very persistent character and was readily controlled by sponge-baths. A flaxseed and mustard poultice— 1 part of mustard to 9 parts of flaxseed—applied as hot as could be borne by the back of the nurse’s hand, and changed every half-hour, gave much relief from the pain during the acute stage. After the first twenty-four hours, however, poultices are of little value. Strapping the affected side with strips of Z. O. plaster will give much comfort when the pain con- tinues after the second day. Tincture of aconite in doses of 1 drop every hour may be given to older children until 10 drops have been given. This has produced a fairly free diaphoresis and made the patients more comfortable. A grain of calomel in divided doses may be given early in the attack, 1/10 grain being given every ten or fifteen minutes. To relieve the cough, small doses of codein, 1/10 grain every two hours, may be given the older children. The duration of the acute symptoms is ordinarily from twelve to twenty-four hours, the entire duration of the illness ranging from five days to one week. In the case of effusion in our youngest patient absorption appeared to be stimulated by the introduction of the needle and the withdrawal of a small amount of fluid, the remainder quickly disappearing afterward. Ultimate Results.—That the cases observed were not of tuberculous origin was strongly indicated not only by the absence of the tubercle bacilli, but by the complete recovery and continued good health of each patient during the next few years. SECONDARY PLEURISY Etiology.—Tins form of pleurisy is of very frequent occurrence in the young, and in by far the larger number of cases occurs as a complication of pneumonia. Tuberculosis is probably the next most frequent cause. Secondary pleurisy may occur with pericarditis; such an association, however, is rare. Bacteriology.—Acute fibrinous (dry) pleurisy accompanying pneu- monia in children is caused by the identical micro-organism found in the consolidated areas of lung tissue. This type of pleurisy is more com- mon with lobar pneumonia than with bronchopneumonia. In acute serous pleurisy accompanying pneumonia small numbers of pneumococci may be found in the fluid. Clear, serous, pleural fluid containing streptococci has been described. In the tuberculous cases the fluid contains the tubercle bacillus, demonstrable by staining methods or by intraperitoneal injection into guinea-pigs. On ordinary culture-media tuberculous serous fluids give no growth. Pleurisy with serous effusion may occur with acute rheumatism. Pathology.—Following or coincident with pneumonia there may occur what is known as dry pleurisy, or pleurisy with effusion. When dry pleurisy exists, the pleura loses its usual luster, and, early in the attack, is covered with a slight fibrinous exudate. Exudation may go no further than this, or it may become most extensive, resulting in a TIIE PRACTICE OF PEDIATRICS network of fibrinous bands, in the meshes of which there is a thick, gelatinous mass composed largely of fibrin and pus-cells. Repeatedly at autopsy the lung will be found so thoroughly bound to the chest wall that its removal without the aid of force is impossible. In pleurisy with effusion a fluid composed either of pus or of serum will be found in the pleural cavity. We have never seen such a case of pleurisy secondary to pneumonia in which the effusion did not contain bacteria. The fluid upon withdrawal may appear clear, yet bacterio- logic examination will show that it is not sterile. The evidence of bac- teria in the fluid may be, and often is, the first manifestation of a purulent pleurisy or empyema. Pleurisy of tuberculous origin may or may not be of the dry type. Tubercles may be found on the pleura, and there is more or less exudation of fibrin. If the process is an old one, there is considerable thickening of the pleura, with very firm adhesions. Effusion, when present in this type, often exists in small amount—1 to 4 ounces—sacculated, and may be serous or purulent. Symptoms.—Secondary pleurisy rarely exhibits distinct symptoms of its own. The manifestations are a part of the disease which the pleurisy complicates. There may be localized pain, but this is rarely of an active type. A sensation of tightness or constriction is more common, and it is surprising how little discomfort is present in a vast majority of the cases. When fluid is formed, whether serum or pus, there are, again, no active symptoms unless the fluid is excessive, in which event there will be interference with respiration, and, if the process is on the left side, the heart will show the effects of the pressure by rapidity and perhaps irregularity. The influence that the pleurisy exerts upon the temperature is difficult to determine, as the process is secondary to diseases in which temperature is a prominent feature. If the exudation is purulent, the temperature may take on the characteristic morning drop and evening rise. This will be very apt to occur in case of purulent exudation following pneu- monia (p. 388). Diagnosis.—The diagnosis is dependent more upon the physical signs than upon the symptoms. Auscultation.-—In the cases without fluid exudate auscultation will often detect either fine friction rales, which may be heard only at the end of inspiration, or the dry rubbing friction crepitus heard with both inspiration and expiration. In the presence of fluid there may be weak- ness of, or absence of, respiratory murmur over the area covered by the exuded fluid, and the characteristic egophony at the level of the fluid. Rales will be absent. Over the uninvolved lung area there will be an exag- geration of the normal respiratory sounds. Percussion.—In dry pleurisy there is no perceptible dulness. The child may complain that the percussion is painful. With fluid there will be dulness or flatness, depending upon the amount of fluid present. A small amount usually gives circumscribed dulness; a large amount, extreme dulness or flatness. Over the uninvolved portion of the lung there will be hyperresonance. With a large accumulation the heart may be displaced. SECONDARY PLEURISY 387 x-Ray.—Radiographic findings are usually definite, but do not always give the differentiation clearly between fluid and consolidation. Exploratory puncture if successful not only definitely determines the presence of fluid but also its nature. Treatment.—The treatment of dry secondary pleurisy is usually that of the disease which the pleurisy complicates. We have never known special medication to be of any practical value. Tonics and supportive measures generally are of service. Anything that will improve the con- dition of the patient should be brought into use. A change of residence from the city to the country for those who can afford it, or an outdoor life in the city for those who cannot avail themselves of such a change, is always beneficial. Counterirritation to the chest with mustard or iodin will often give relief to the patient if there is pain, but otherwise this measure pos- sesses no value. When there is a sense of “tightness” and constriction of the chest which amounts to pain counterirritation will relieve the discomfort. The application of a mustard plaster (p. 846) — one-third mustard and two-thirds flour—to the bare skin over the diseased area for ten or fifteen minutes, at intervals of six or eight hours, will add to the comfort of the patient. Painting the affected area with tincture of iodin every second or third night has, in a few cases, afforded some relief. The administration of iodids as an aid to absorption is of questionable value, and is very apt to disturb the digestion. When, after recovery from the pneumonia or the empyema, adhesions persist compelling restricted lung action, active exercise in the open air is to be encouraged. For younger patients horseback-riding, the bicycle, and breathing exercises, with physical games which call for active inter- est and require deep breathing give the best results. Presence of Fluid.—If the exploratory puncture shows the presence of serum, the fluid is best left, with the hope that it will be absorbed, unless it is in sufficient amount to compromise the respiratory function and the action of the heart. In such an event as much as possible without undue inconvenience to the patient should be removed by aspiration. In many cases the fluid rapidly disappears after one aspiration. If this outcome is not attained, aspiration is to be repeated. During this operation care should be exercised to observe absolute asepsis. We have known clear exudate to become rapidly purulent after the insertion of a needle. There is always a question in such instances, how much infection has been carried in on the needle. The skin should be thoroughly scrubbed with green soap. This is to be followed by wash- ing with alcohol, and then with equal parts of alcohol and tincture of iodin. The hands should be cleaned, and the instrument used should be sterilized, as for a surgical operation. If the pleurisy is of tuberculous origin no particular management is demanded other than that of the primary disease, except in the event of symptoms of pain. This is to be relieved, as already described, by the use of local applications of mustard and iodin, with perhaps the administration of a sedative, such as small doses of codein. Dry pleurisy associated with pericarditis does not call for treatment other than that of the pericarditis. 388 THE PRACTICE OF PEDIATRICS EMPYEMA (PLEURISY WITH PURULENT EFFUSION) In empyema there is a collection of pus in the pleural cavity, result- ing from inflammation of the pleura which has become infected with pathogenic organisms. Age.—A vast majority of the cases occur in infants and children under four years of age. The senior author’s youngest patient was three weeks old, and this child recovered. Comparatively few cases develop after the tenth year. Etiology.—In 95 per cent, of our cases the disease has occurred with evident pneumonia. Empyema may follow suppurative processes in any part of the body, but such cases are extremely rare. Bacteriology.—The pneumococcus is found in pure culture in the pus in about 75 per cent, of all cases in children. The streptococcus is less commonly present, and the Staphylococcus aureus is very rarely found. Bacillus influenza has been found in pure culture in purulent pleural fluid after influenzal pneumonia, and B. typhosus may cause empyema during an attack of typhoid fever. From empyema following inflammatory conditions in the abdomen (appendicitis or peritonitis) B. coli communis has been isolated. Purulent effusion accompanying pulmonary tuberculosis may con- tain the tubercle bacillus, but pyogenic cocci also are almost always present. Pathology.—A purulent pleural exudation may follow serous in- flammation of the pleura, or the process may be purulent from the outset. The pus may be thin or thick, yellowish or greenish in color, and may con- tain large masses of fibrin. The quantity of purulent fluid may vary from a few ounces to 30 to 40 ounces or more in neglected cases. While the inflammation may involve the entire pleural surface of one lung, and even involve both pleural cavities it is more often limited to the lower lobe and to the posterior portion. The pulmonary and costal sur- faces of the pleura are usually covered with a fibrinopurulent exudate, and adhesions between the pleural surfaces and between the pleura and pericardium are readily separated at this stage. The lung substance beneath the exudate is more or less compressed, according to the amount of pus present. In extreme cases the affected lung portion may be com- pletely airless, bloodless, gray in color, smaller than normal, and flattened against the vertebral column. The heart may be pressed toward the healthy side. In less severe cases the lung may be congested and still contain some air. Empyema may heal completely in the early stage. Very often, however, it tends toward a chronic course. The pus frequently becomes very thick, and the formation of granulation tissue, and later of fibrous connectiye tissue, causes irregular thickening of the pleura. Adhesions between the pleural surfaces may thus be so dense as to make separation impossible, and an encapsulated empyema may be formed by the shutting off of a smaller or larger amount of pus by adhesions. The connective- tissue formation may finally extend into the lung substance, resulting in interstitial pneumonia. In cases of empyema which come to autopsy early in the disease the pneumonia preceding the empyema may still be present. In later stages, EMPYEMA (PLEURISY WITH PURULENT EFFUSION) 389 however, only a complicating bronchopneumonia, acute or chronic, may be found in one or more of the lobes not involved by the empyema, or an interstitial pneumonia in that portion of the lung substance beneath the thickened pleura. In untreated cases the pus may be evacuated through a bronchus, externally through the chest wall, or into the peritoneal cavity. When absorption and spontaneous “cure” occurs without rupture fibrosis of the lung is frequently produced. Symptoms.—Empyema after Bronchopneumonia.—'The child has bron- chopneumonia, running the usual course as to fever, respiration, pulse, and prostration. After a time varying from six to twelve days an im- provement in the symptoms is noticed; the pulse and respiration become slower, and the child appears brighter. During the height of the pneu- monia the temperature has been perhaps 104° to 105° F. Now it ranges Fig. 75.—Temperature chart. Empyema following lobar pneumonia. from 100° to 102° F., at times dropping to 99° F. For twenty-four to forty-eight hours the temperature range is quite low. Soon it becomes noticeable that the fever is higher in the evening than in the morning, although the evening temperature may not be above 102° F., or at most 103° F. The child coughs, the pulse is rapid—120 to 140—and the respiration is accelerated to 40 or more. The appetite is poor. These or similar symptoms may continue for weeks if the condition is not recog- nized. Empyema After Lobar Pneumonia.—Empyema more frequently fol- lows lobar pneumonia than bronchopneumonia. The following sympto- matology covers a majority of the cases: The crisis occurs, and the tem- perature falls to normal (see Fig. 76) and remains normal for a few days; or perhaps there is the temporary postcritical rise the day following the crisis. In other respects conditions continue favorable for perhaps two, three, or rarely five days, when a slight evening rise in temperature oc- 390 THE PRACTICE OF PEDIATRICS curs. The temperature is lower the next morning, but perhaps not quite normal; the following evening it is higher than the preceding, and the next evening it is still higher. Such a temperature range following pneu- monia is almost pathognomonic of empyema (Fig. 76). In some few cases the exudation of pus into the pleural cavity is not delayed until the temperature falls, but develops during the first few days of the pneumonia. With the formation of pus the respiration and pulse increase in frequency, the respiration ranging above 40, and the pulse from 140 to 180. It is a mistake, however, invariably to expect characteristic signs. The lungs and heart soon accommodate them- selves to the changed conditions. Repeatedly we have seen cases in which there was but slight acceleration of the pulse and respiration. The evening temperature, however, is rarely less than 102° F. In addi- tion to the symptoms enumerated, these cases (particularly those that Fig. 76.—Empyema following lobar pneumonia. Operation. Recovery case. have continued for two weeks or longer) show a symptom-complex that may almost be said to be characteristic. The child is emaciated and his face wears an anxious expression. The skin is pale, of a yellowish tinge, and perspires readily. The mucous membrane and conjunctivse are pale. Slight exertion causes embarrassment of the respiration. The nostrils are distended; the respiration during rest is short, and increased from 10 to 20 per minute above the normal. The fingers may show signs of clubbing. The blood, which has perhaps shown during the pneumonia a leukocytosis ranging from 15,000 to 25,000, with the development of empyema may afford leukocyte counts of 35,000 or higher. Diagnosis is based upon physical examination of the chest, rr-ray examination, and exploratory puncture. Weakness or absence of respira- tory murmur and absence of r&les, combined with the presence of dulness or flatness, are indications justifying an exploratory puncture. EMPYEMA (PLEURISY WITH PURULENT EFFUSION) 391 When the disease is located on the left side, the displacement of the heart to the right, as indicated by the changed position of the apex-beat, is a very suggestive sign. Over the uninvolved portion of the chest auscultation will show exaggerated respiratory murmur; and percus- sion, hyperresonance. Differential Diagnosis.—Empyema is to be differentiated from serous pleurisy, pleurisy with massive exudation of fibrin, unresolved pneu- monia, pulmonary tuberculosis, malaria, pyelitis, otitis, and typhoid fever. The value of routine blood and urine analysis in such differentiation is at all times to be kept in mind. Serous pleurisy and pleurisy with a thick, fibrinous exudate give signs identical with those of empyema. In many cases of fibrinous pleurisy with a considerable exudate not a rale or friction sound will be heard. Our only means of differentiating empyema from these processes is ex- ploratory puncture with a large needle. In unresolved pneumonia the respiratory sounds are heard with greater distinctness. Rales, and often friction sounds, are present. The dulness is distinctly localized, and there is rarely flatness unless there is associated with the pneumonia a thick pleuritic exudate. In tuberculosis of the lung of sufficient gravity to allow of confusion the presence of tubercle bacilli in smears from the expectoration or tracheal secretion (see p. 396) may determine the diagnosis. The intradermal tuberculin test (p. 825) and x-ray examinations may be brought into use. Here also, however, the exploratory puncture is the best means of estab- lishing the diagnosis. The difficulties in differentiating typhoid fever and malaria from empyema should be slight in view of the marked dissimilarity in the disease conditions. Nevertheless, cases of pleurisy are not infrequently treated for typhoid and malaria when pus is present in the pleural cavity. Whenever the lungs are proved normal by competent physical examination, the tests for malaria and typhoid in daily use should be instituted. Treatment.—When pus is located, operation and drainage are the only methods of treatment. Aspiration is never to be looked upon as a substitute for incision. In a recent case in a young child under two years of age an incision with local anesthesia—ethyl chlorid answers the purpose—is at times permissible. In the case of an older child, or in a prolonged case in a young child, partial resection of a rib under general anesthesia is to be advised as furnishing much freer drainage. Occasionally cases are seen among older children in which, on account of a very severe, persisting pneu- monia, it will not be safe to use a general anesthetic. In such cases an incision may be made under novocain—a 1 to 2 per cent, solution being injected into the skin at the site of the proposed incision. Such an opera- tion will relieve the immediate symptoms—the displacement of the heart and the difficult breathing. The resection of a rib may safely be under- taken after a week or two, when considerable improvement will have taken place in the general condition. As soon as the cavity is opened, two drainage-tubes, from 2 to 4 inches in length, joined with a large safety-pin, are inserted. Gauze is packed around the tubes and 392 THE PRACTICE OF PEDIATRICS against the skin, and upon this the pin rests. Sterile gauze is placed over the end of the tubes as soon as possible after their introduction in order to prevent too free escape of pus. When the pus is allowed gradually to escape, much less shock will be experienced. Over the gauze two or three layers of absorbent cotton are placed, and over this the bandage. The dressing should be changed every day and the tubes short- ened as the lung expands. This expansion will be indicated by the resulting outward displacement of the tubes. After the evacuation of the pus the pulse usually falls to normal or nearly normal, where it remains. Oc- casionally, however, this expected result does not follow the operation. Illustrative Case.—In one case the operation was followed by a free discharge of pus, but with no relief whatever to the symptoms. An examination of the chest re- vealed at the apex of the lung a pocket of pus which had become walled off by adhe- sions. The case was one of three months’ duration when it came under the writer’s care. A second operation removed about 6 ounces of pus, but the child died from exhaustion about twenty-four hours afterward. Autopsy showed that the pleural cavity was divided into two distinct pus-sacs by a firm band of adhesions. Failure of the temperature to subside in our cases in which complica- tions could be excluded has been due to defective drainage. The tube may be too small or plugged, or the pus may become sacculated. Large fibrinous masses which the tube will not admit may undergo slow de- generation and absorption and continue the temperature. Illustrative Case.—In a case of empyema following pneumonia of great severity in a girl of five years, on account of the reduced condition of the child, an incision was made instead of a resection of the rib. The temperature fell to normal, and all the symptoms improved for a few days, when an evening rise to 101° F. was noted, which in two or three days reached 103° F. There was a discharge which saturated the dressings, although they were changed every three or four hours. Our inability to locate an independent pus-pocket, the continued fever, and a strong odor to the dis- charge suggested the probability of insufficient drainage. In spite of the fever, the child having gained considerably in strength, a second operation was decided upon to enlarge the wound. She was anesthetized, and 2 inches of rib were removed, where- upon quantities of necrotic fibrinous material were found in the pleural cavity. These were removed with the finger and dressing forceps; the temperature immediately fell to normal, and the child made a perfect recovery. Irrigation of the cavity had been of no avail. Ordinarily the tubes should not be removed until from two to six weeks after the operation. At least one tube should be kept in posi- tion until a free respiratory murmur is heard all over the affected side, up to the site of operation in the chest wall. When the lung is fully expanded the tubes will be forced out and found in the dressings. Irri- gation of the pleural cavity with Carrel-Dakin solution is at times of value, but with sufficient drainage is rarely found necessary. The cases which require irrigation on account of continued fever and insuffi- cient discharge require the resection of a rib. Should a second opera- tion be refused, on account of the tender age or the general weakness of the patient, or be inadvisable on account of some complication, such as a pericarditis, a daily irrigation with the Carrel-Dakin solution may be undertaken. Deformity Following Untreated Cases.—In hospital and out-patient work cases neglected for weeks, showing marked chest deformity and retraction, usually associated with spinal curvature, are among those PULMONARY GANGRENE 393 treated. The pus has been partially absorbed and partially organized, leaving extensive adhesions which have bound the lung tightly to the chest wall, preventing expansion, so that the bony wall has become dis- placed inward to meet the lung. For these unfortunate children surgi- cal measures furnish some relief, but the results have not been brilliant. Suction Drainage.—Various methods have been devised to favor the escape of pus without the admission of air to the pleural cavity. Such methods are undoubtedly of value in selected cases, particularly when the pus content is not thick or marked by the presence of large amounts of pyogenic membrane. The old-time practice of rib resection and drainage is, however, still favored by many conservative surgeons. Double Empyema.—But 2 cases coming under our observation have had both pleural sacs involved. In such cases both sides should not be opened at the same time, on account of the danger of collapse of the lungs. There are usually adhesions present sufficiently strong to prevent this, but we have no means of knowing beforehand. In both of the cases the left pleural cavity was opened first in order to relieve the pressure upon the heart and the great vessels. Illustrative Cases.—In one case a considerable quantity of pus was removed from the right side by aspiration at the time of the operation on the left side. The right side was operated upon four days later, by which time sufficient adhesions had formed to prevent collapse of the lungs. The patient, a boy of two years, made an excellent recovery. The second patient was one year of age. Pus had been present in both sides for a considerable time. The left thoracic cavity was opened first. The sac on the right side was smaller than that on the left, and was operated on by incision three days later. The child was very much reduced by the protracted illness. In spite of the free daily irrigation of both cavities the typical temperature persisted, probably on account of the very extensive suppurating surfaces. The child died from exhaustion twelve days after the second operation. Empyema Necessitatis.—Spontaneous rupture of the pleural sac may occur in cases of empyema of considerable duration which are not promptly diagnosed or not operated upon if diagnosed. Cases of this nature have been reported in which the pus ruptured into the esopha- gus, into the bronchi, or through the diaphragm into the peritoneal cavity. Illustrative Cases.—Case 1.—In the case of a well-nourished boy three years of age the pus had been sacculated over the anterior portion of the left lung. The parents, not particularly intelligent people, objected to operation, and while it was under consideration by them, two or three days after the diagnosis was made, the pus rup- tured into the bronchi and was discharged from the mouth in large quantities during a coughing paroxysm. The child made an uninterrupted recovery. Case 2.—Another patient, a boy of two years, came under observation for a soft fluctuating swelling, the size of a small orange, on the right side, immediately below the nipple. Exploration with a hypodermic needle showed pus. An incision was made and about 3 ounces of pus were evacuated. When the sac was emptied it was found to communicate with the right pleural cavity by an opening between the seventh and eighth ribs. The wound was dressed and the child recovered without further complications. PULMONARY GANGRENE Pulmonary gangrene is a very rare complication of pneumonia. Three cases observed by the writer all developed during the course of a broncho- pneumonia. The gangrene is supposed to be due to an embolism of some branch of the pulmonary artery or to a septic thrombosis. The odor 394 THE PRACTICE OF PEDIATRICS of the breath is most characteristically offensive and actually beggars description. As a complication of pneumonia pulmonary gangrene is invariably fatal. Except for the odor of the breath there are no significant symptoms which may not exist with the usual attack of bronchopneumonia. PULMONARY ABSCESS Pulmonary abscess, except in the form represented by small foci which may exist in bronchopneumonia and are not recognizable clinically, is a very unusual complication of pneumonia. Comparatively few cases are diagnosed, because of the occurrence of the abscess with empyema or because symptoms resembling empyema are present. The abscess is usually discovered during exploration for pus in the pleural cavity or at the time of operation for empyema. a>Ray may reveal the condition. Lung abscess may occur as a sequel to tonsillectomy. Whether this occurrence is to be ascribed to aspiration of septic material during opera- tion or to metastasis of bacterial emboli through open blood channels is a moot question. As a rule, any form of insufflation anesthesia is con- traindicated in tonsil operations. (See p. 381). Illustrative Case.—A child had pneumonia of the right upper lobe, which failed to resolve after abatement of the urgent symptoms. The temperature continued at 101° to 102° F., and there was a distressing cough. For this a mixture was given con- taining full doses of syrup of ipecac and ammonium chlorid. This was given repeat- edly without dilution, against instructions, and produced violent emesis. During a vomiting seizure the child brought up a considerable amount of pus, after which the recovery was prompt. Evidently the straining had produced a rupture of a pulmonary abscess into one of the larger bronchi. PULMONARY TUBERCULOSIS Infection of the lungs with the tubercle bacillus constitutes the chief type of tuberculosis in the human. The lungs are the most active seat of the process in at least 90 per cent, of the cases. Pathology.—In the most acute form of pulmonary tuberculosis the lungs contain gray, translucent tubercles in varying numbers. These may be only few in number, or may be very closely studded throughout both lungs. The lesions may also be present on both surfaces of the pleura. Acute bronchopneumonia, with or without fibrinous pleurisy, is a frequent complication. In a late stage the tubercles undergo cheesy degeneration and are yellow in color. The coalescence of neighboring tubercles may give rise to cheesy masses, which eventually undergo softening. The tubercles are more often peribronchial than perivas- cular in distribution. Owing to the more direct course of the right main bronchus, the right lung is often involved before the left. Caseous degeneration of an area of pneumonic exudate may occur, and the resulting cheesy pneumonia frequently leads to softening and cavity formation. These cavities may occur in any part of the lung, but are most common in the right middle and upper lobes, and usually communicate with a bronchus. Their walls are irregular and grayish in color, are often crossed by blood-vessels, and contain caseous necrotic material. PULMONARY TUBERCULOSIS 395 The connective tissue of the lung is increased in cases of pulmonary tuberculosis which have undergone repeated attacks of pneumonia, or which follow empyema of long standing. In such cases the pleura also is thickened and may be covered with an organized exudate. Phthisis as it is seen in the lungs of adult subjects is seldom met with in children under eight or ten years of age. The bronchial lymph-nodes in cases of pulmonary tuberculosis are involved in the tuberculous inflammation in about 97 per cent, of the cases. The nodes are enlarged, and on section show all stages of tuber- culosis, from discrete tubercles with small cheesy centers to cheesy de- generation of the entire node. Softening or suppuration is very common, while calcareous degeneration of a tuberculous focus in a lymph-node is infrequently seen in infants, but is less rare in children over two years of age. The bronchial and mediastinal lymph-nodes may be so much enlarged as to afford dulness on percussion and occasion respiratory difficulty from pressure. Symptoms.—In infants and very young children there is no char- acteristic symptomatology. This seems strange in a disease of such gravity. Even in the miliary type, where we have been taught to ex- pect high temperature, rapid respiration, and other severe toxic symp- toms, such symptoms do not always exist. The signs correspond to those of bronchopneumonia—fever, 101° to 104° F., rapidity of respira- tion, cough, and the chest signs peculiar to catarrhal pneumonia. There may be only cough and the evidence of a generalized bronchitis. The temperature range is not characteristic, and may not differ from that of bronchopneumonia. A suspicious symptom in an infant is steady emaciation out of pro- portion to the other positive evidences of disease. The child takes food well, sleeps well, and is comfortable. There may be a slight elevation of the temperature or no elevation throughout the illness—in fact, the temperature may run a subnormal course. The picture is that of marasmus. In older children after the third year the disease manifests itself by more distinct signs, such as emaciation, loss of appetite, fatigue on slight exertion, and perhaps night-sweats. There is, moreover, a trou- blesome dry cough with little expectoration. Elevation of tempera- ture in older children is almost an invariable symptom. It may not be high, however, perhaps not above 101° F. in the evening. The child complains of chilliness and soon shows signs of anemia. Pain is unusual and hemoptysis rarely occurs. In the miliary type in older children the symptoms are also active, particularly the temperature, which will range very high—103° to 105° F. —or it may be low in the morning and high at night. The respiration and the pulse are rapid. Cough is not a prominent symptom. There is rapid loss in weight. It will be observed that the symptoms may aid us but little. The z-ray is of great value, but leaves opportunity for misinterpretation in differentiating such conditions as fibrosis and non-tuberculous broncho- pneumonia from actual tuberculosis of the lung. Diagnosis.—For the positive diagnosis of tuberculosis in children 396 THE PRACTICE OF PEDIATRICS the presence of the tubercle bacilli must be proved. The examination of the lungs, except by showing the existence of a cavity, aids us but little, for, in the miliary type, there may be tuberculosis without chest signs. The various lung changes evident on examination may differ in no way from those which may be found in acute or chronic broncho- pneumonia. Accompanying tuberculosis, moreover, there may be a bronchial catarrh, which in no way differs in its manifestations from that of simple generalized bronchitis. A positive intradermal tuberculin test (p. 825) is strong corroborative evidence of tuberculosis in young infants. The presence of fine crepitant rales localized over the right middle lobe (front) often means a localized tuberculous process, the bacilli being conveyed by the lymphatic channels extending from the bronchial glands to the spaces between the middle and upper lobes. The value of this sign has been proved in a large number of cases. In the case of older children the tuberculin test, while positive, may be misleading, as the tuberculosis may be latent or entirely healed, and have no bearing on the immediate illness. x-Ray diagnosis of tuberculosis in children is invaluable, but calls for interpretation based on large experience. Mediastinal adenopathy and peribronchial infiltration indicated by fan-shaped shadows radiating from the root of the lung may be easily detected, but do not always spell '‘tuberculosis.” Repeated examinations are essential. The D’Espine sign, while of value, is only an aid (see p. 810). After the fourth or fifth year the diagnosis is seldom beset with the difficulties encountered in infancy. At the later period of life localized signs of bronchitis, or partial or complete consolidation with dulness, may be manifest. Further, children at this age expectorate, so that collection of the sputum is easily accomplished. Methods of Obtaining Sputum.—In dealing with infants who do not expectorate a satisfactory method of obtaining the bronchial secretion is to pass a sterile catheter into the child’s larynx. This excites coughing so that the secretion is brought up through the larynx and adheres to the tube. Another method which may be used consists in irritating the pharynx with a small piece of sterile gauze grasped in an artery clamp. As a result of the coughing thus induced the secretion from the trachea will be de- posited on the gauze. Several tests may be necessary before the bacilli are discovered. Bacilli in the Stool.—To search for bacilli in the stool is not a very satisfactory procedure, and is not necessary, in view of the success at- tending the above methods of securing material for examination. In suspicious cases in which the sputum examination fails to reveal sthe bacillus the stools should be examined. Prognosis.—The prognosis for infants is very unfavorable. Never- theless in infants healed tubercular foci are occasionally found at autopsy. A child eighteen months of age who died of diphtheria had a large encysted calcareous tubercular nodule in the left lung, 1 inch by H inches in size. Likewise the bronchial glands may show evidences of previous disease. In view of the large percentage of positive reactions to the von Pirquet skin test in children past ten years of age it would seem that there are PULMONARY TUBERCULOSIS 397 many more cured cases in children than has heretofore been appreciated. After the fifth year, if the case is seen reasonably early, if the child has a fair resistance, and if the management can be suitably carried out, the prognosis is very good indeed. The prognosis is further favorable if the infection is primary. If there is a lighting up of an old tubercular lesion in the bronchial glands or elsewhere the prognosis is much less favor- able. Recoveries in New York City have been frequent in primary cases of children who could not be sent away. Associated Lesions.—The invasion of the tubercle bacillus usually means the involvement of more than one organ or portion of the body. The Liver.—An autopsy in a case of pulmonary tuberculosis will very frequently show, in addition to the evidences of the disease in the lung and pleura, that the liver is involved to the extent of showing a generous distribution of tubercles in its surface and in the liver sub- stance. The Spleen.—It is rare, in making a postmortem examination in pulmonary tuberculosis, not to find the spleen the seat of the disease. Both the surface and the splenic tissue may be filled with tubercular deposits. The Heart.—Tuberculosis of the heart muscle is very unusual. A few cases have been reported. The pericardium is occasionally the seat of a few tubercles. They are usually found when there is an extensive general tuberculosis. Stomach.—Tuberculosis of the stomach is of very rare occurrence. Hale reported having seen but 5 cases in his large autopsy experience. Intestines.—Infection of the intestinal mucosa without further ab- dominal involvement is occasionally seen at autopsy. The kidney is very frequently the seat of tuberculosis. About 25 per cent, of the writer’s cases have shown such lesions. They are usually of the miliary type, scattered over the surface, with a few in the kidney substance. Tuberculosis of the larynx in children is of very unusual occurrence. Demme reported a case in a child four and one-half years old (Koplik). The pancreas, thymus gland, and peritoneum are rarely at autopsy found to be the seat of a few miliary tubercles. Tuberculosis of the cervical lymph-glands, brain, mesenteric glands, peritoneum, and abdomen will be discussed in separate chapters. Treatment.— Climate.—For those who are so situated financially as to have the advantages of an equable climate, a change of residence or sanitarium treatment should be provided. A dry climate of equable temperature that will allow the tuberculous child to spend the greatest number of hours in the open air is best. The climate of southern New Mexico and Arizona is exceptional for these cases. Children do well in the Adirondacks and in Sullivan County, New York, but the severity of the winter makes these localities less desirable. Diet.—Equally important, if not more so than climate, is the nutri- tion of the patient. This must be raised to the highest possible stand- ard, but there should be no overfeeding, such procedure being of no value in any disease in the young. A liberal protein diet of milk, meat and eggs, oatmeal, and the legumes—dried peas, beans, and lentils, 398 THE PRACTICE OF PEDIATRICS which are given in the form of a puree, is to be recommended. It is not wise to insist that a definite amount of food be given in twenty-four hours. The mother or nurse is to be told, however, that these foods, prepared in different ways so that the child will not tire of them, are to form a considerable part of the diet. Green vegetables and fruits should be given because of their salt and vitamin content. When three meals a day are given, with, perhaps, a glass of milk in the middle of the afternoon, better nutrition may be maintained than with more frequent feedings which often defeat their own purpose by producing disgust for, or intolerance of, food. The child should be fed on nutritious food, for which an appetite must be developed; for, inasmuch as recovery is dependent largely upon nutrition, the question of appetite and food capacity is of paramount importance. Candy, sweet crackers, and other harmful articles should not be allowed. In order to satisfy the candy craving a small quantity of sweet chocolate may be given after the noon- day meal. The best appetizers are reasonable exercise, entertainment and play that do not fatigue, and fresh air in abundance. Upon our ability to meet these requirments depends, to a large degree, the outcome of the case. The majority of the children with pulmonary tuberculosis cannot be sent to sanitariums or to health resorts, but must be treated in their homes. This is accomplished successfully in New York City even among the tenement population. The basic principles of management comprise a properly directed life, good food, and fresh air. These are the weapons for fighting the enemy, regardless of whether the residence is among the rich or poor, in town or in country. It is, however, among the tenement population that we experience the greatest difficulty. To tell these people how the child is to be fed is not enough. The feeding as directed entails considerable expense, which the parents may not be able to meet. If after personal investigation (which should be made in every case) it is demonstrated that proper nutrition or suitable clothing is impossible, the writer has often explained the situation to some charitably inclined person of means, and has yet to know of an instance in which clothing and a small but sufficient weekly food allowance were not forthcoming. An allowance of 25 cents a day for fresh meat and milk has often fur- nished what was required to bring the case to a favorable termination. The uselessness of much of our medical advice to the poor would, on slight reflection or a little investigation, be apparent. Directions are too often given for the care of the sick which are absolutely impossible of fulfilment. Hygiene.—In addition to the diet above outlined, the advantages of an outdoor life, and the means by which fresh air may be obtained all the year round, should be fully explained. Any simple direction as to what may appear to be a radical procedure is rarely carried out with- out a rational explanation of its necessity. During the daytime the child should be kept outdoors. Close, tightly sealed sleeping apart- ments at night, however, will undo the good of the outdoor life during the day. The mother should be told to have the child sleep alone in the largest room of the apartment, and always in a room in which the windows are opened. This is usually possible. A sponge-bath or tub- bath should be given at bedtime, followed by brisk rubbing with a towel. 399 HELIOTHERAPY If there is much emaciation, an olive-oil or goose-oil inunction should follow the salt bath. Sometimes these directions are followed implicitly; at other times they are forgotten. It is astonishing, however, what rapid improve- ment will follow when a tuberculous child of the tenements is given the benefit of fresh air, day and night, with suitable food and cleanliness, even though the conditions are those of a great city. Among the more fortunate classes the same method of treatment, of course, with a more satisfactory application, is to be carried out. Among the well-to-do, however, we see fewer cases. Tonics.—The usefulness of drugs depends to a large degree upon an increase of food capacity which their use may cause. Any of the prescriptions written below may be used alternately with cod-liver oil and malt, each being given for five days. For a child from seven to twrelve years of age the following are useful restoratives and appetizers: 1$. Tincturae nucis vomicae gtt. xlviij Saccharini gr. iss Aquae q. s. ad. 3iv M. Sig.—One teaspoonful every two hours. (Six doses daily.) 1$. Ferri et quininae citratis gr. xlviij Vini xerici 5iv M. Sig.—One teaspoonful in water three times a day after meals. R. Tincturae nucis vomicae gtt. lxxv Extracti ferri pomati gr. vj Quininae bisulphatis 3j M. ft. capsulae no. xxx. Sig.—One after each meal. If night-sweats occur, from 1/200 to 1/160 grain of atropin at bed- time will often furnish relief. Care of the Sputum.—Various devices for collecting the sputum may be obtained in the shops. A cheap and effective method is the use of a Japanese handkerchief or paper cup which, when used, is at once placed in a paper bag, the bag and its contents being burned at the close of the day. The dangers of infecting others should be fully explained to those in charge of the patient, kissing and fondling being forbidden. Heliotherapy Heliotherapy, or the treatment of bodily ills by exposure to the sun’s rays, has been utilized for curative purposes many centuries. In the Swiss Alps Rollier and Bernhard were the first to take up heliotherapy in a scientific manner for the definite end of curing tuberculosis. The method is very simple and consists in exposing the body to the direct rays of the sun for a given time. Most satisfactory results are reported by the above authors, particularly in cases of surgical or bone tuberculosis. This method of treatment of tuberculosis as carried on by Dr. Gerald Webb of Colorado Springs is described as follows: "Children can be ex- posed naked at an altitude of 4000 to 5000 feet when snow is on the ground because the temperature in the sun may be as high as 90° or even 120° F. Patients arriving at this altitude are first allowed to become acclimated 400 THE PRACTICE OF PEDIATRICS by rest indoors for a few days. Then they are placed on verandas with a white garment covering the body.” “Exposures to the sunlight are made very cautiously and gradually, fixed rules being followed no matter what part of the body may be affected with tuberculosis. On the first day the feet are exposed three or four times at hourly intervals for five minutes each time.” “On the second day the bare legs to the knees are exposed in a similar manner, and the feet are exposed three times for ten minutes each. On the third day these exposures are increased by five minutes, three times daily, and on the fourth day the thighs are included. On the fifth day the abdomen and chest respectively are exposed. The pulse and tem- perature variations are used in guiding the treatment, and for certain individuals variations in the sun treatment are made. By this method in summer or winter patients can remain from four to six hours bathing in the sun.” “Naturally, other surgical methods are not neglected. Splints, braces, and the like are employed when necessary to limit motion in diseased joints. The appliances are made as light and as open as possible. Open wounds when not being sunned are dressed with gauze soaked in al- cohol. Such “open” cases are found more refractory to the treatment than “closed” cases.” “Certain blood changes have been noted, such as an increase in the phosphorus content and the number of the red blood-corpuscles. Some observers, too, have claimed that the lymphocyte blood-cells—known to be antagonistic to the tubercle bacillus—are increased by helio- therapy.” “We feel it wise to warn patients against the careless employment of sun baths without proper medical control, as harm can be done by them. The head should be protected, especially at first, by a light hat, and in the case of adults R oilier sometimes advises the covering of the heart with a wet compress.”1 The range of application of heliotherapy is being rapidly extended as its influence on phosphorus and calcium metabolism in rickets is being better appreciated, and the value of the method in the treatment of tuberculosis is now indubitably established.

DISEASES OF THE HEART DIAGNOSIS IN DISEASES OF THE HEART Auscultation.—In the diagnosis of the different cardiac lesions in children auscultation is by far the most useful means at our command, and for this reason may receive foremost consideration. For adults the physician employs auscultation, either with the unaided ear or with the stethoscope, at the following chest areas: The aortic area. The pulmonary area. The tricuspid area. The mitral area. In children tricuspid disease is of most infrequent occurrence. The pulmonary valves are involved only in congenital heart disease. In the routine examination for heart lesions in children the findings are simplified by the fact that aortic and mitral valve lesions are those en- countered in an immense majority of the cases. Owing to the difference in the position of the heart of the child as compared with that of the adult, the various sound areas also differ, and they vary at the different periods of childhood in accordance with the changing position of the heart. Before the sixth year the mitral area corresponds with the apex- beat at a point in the nipple-line, or not more than \ inch without the nipple-line, in the fourth interspace. The aortic area is slightly to the right of the sternum in older chil- dren ; in the very young, over the sternum or at its immediate right border at the level of the second or third interspace, varying with the age of the child. The pulmonic area is on the same plane at the left border of the ster- num. At the end of the sternum, slightly to the left, is the tricuspid area. It is by no means claimed that sound areas indicate the position of the valves, but we know, from combined clinical and autopsy find- ings in children, that murmurs indicating lesions of the respective valves are best heard at these areas. The Normal Sounds.—The normal heart sounds are not easily des- cribed. The normal cardiac cycle is made up of the first and second heart sounds. Listening at the apex or slightly above, one hears at the time of the impulse the low-pitched, dull first sound, followed by the so-called second sound, which is short and higher pitched, and is supposed to be due to closure of the semilunar valves. There is much divergence of opinion as to the cause of the first sound. Most diagnosticians believe that it is due to the contraction of the heart muscle associated with the sudden closure of the mitral valves. The heart sounds vary considerably, depending upon the age of the patient; thus, in the infant both sounds are short and high pitched, and 401 402 THE PRACTICE OF PEDIATRICS the muscle sounds which appear later in life, while present, are not prom- inent. There is rarely difficulty in differentiating the two sounds in the young. The second sound is heard loudest over the base of the heart at points corresponding more or less closely to the pulmonic and aortic areas. In the event of difficulty in differentiation, the first sound should be sought at the apex. On gradually moving the stethoscope upward, the first sound will gradually become fainter, and as the base of the heart is approached the second sound will be heard much more distinctly and loudest in the areas referred to. The points of maximum intensity and areas of transmission of heart sounds in children cannot be arbitrarily laid down. In a general way the landmarks can be indicated, and in most instances will stand. In diagnosing cardiac disease in children we have to consider the age of the patient with particular reference to the size and position of the heart, whether the chest wall is thin and muscular, or fat, and whether the child is crying or quiet. All cardiac sounds in the young are pro- portionately much louder than in adults. In delicate children the sounds vary greatly from those heard in the strong and robust. A first sound, characterized by a muffling or absence of clearness, is very frequently heard in delicate children. After an illness in a strong child this peculiar quality is very apparent, and is without doubt due to muscular insuffi- ciency induced by degenerative changes which in most cases are tem- porary in character. The changed first sound is often interpreted and treated as an evi- dence of endocarditis. In heart failure in serious diseases the muscle element of the first sound gradually disappears so that this sound be- comes short and snappy in quality, due to a degeneration of the heart muscle. The weak muscle sound tends to exaggerate the sound pro- duced by the valve closure. The second sound is caused by the closure of the semilunar valves, and as there are two sets of these valves, the aortic and pulmonary, the aortic second sound in older children is heard in the aortic area, and the pulmonic second sound in the pulmonary area. In babies and very young children a differentiation of the aortic and pulmonic second sounds is unquestionably difficult. The second sound is always accentuated in conditions in which the cardiac vigor is temporarily or permanently impaired, as in myocarditis with hyper- trophy and dilatation of the left ventricle. Inspection alone is of little value in cardiac examination. One learns nothing by inspection that may not be discovered through palpation, percussion, and auscultation. In acute cardiac disease in which there is often a decided overaction of the heart, a decided undulating move- ment of the entire left chest anteriorly will be observed. This usually occurs when there is much dilatation or hypertrophy of the left ven- tricle. Inspection may reveal a retraction of the chest wall at the apex be- tween the fourth and fifth interspaces. This closing in is due to adhesions (the result of a former pericarditis) between the heart, the pericardium, and the chest wall. 403 DIAGNOSIS IN DISEASES OF THE HEART Palpation is useful in determining the position of the apex-beat, in judging of the force of the cardiac impulse, and in the detection of a thrill. The pericardial friction-rub and the heart rhythm may likewise be de- termined in this way. Percussion.—For this examination the upright position is desirable. Percussion is chiefly of value in determining the size of the heart. Hy- pertrophy or dilatation of both the right and left heart may be fairly accurately determined. This method is also of value in determining the amount of fluid in the pericardial sac. Fig. 77.—Diagram, over a normal heart, child nine years, taken at 6 feet distance* R.A., Right auricle; R.V., right ventricle; L.V., left ventricle; L.A., left auricle; P.A.» pulmonary artery; D.A., descending aorta; G.Y., great vessels; M.R., middle right diameter; M.L., middle left diameter of the heart; M.R., 3.5 cm. + M.L., 7 cm. = 10.5 cm. which is one-half the diameter of the chest. (Courtesy of Dr. Charles Winfield Perkins.) The normal right limit of absolute dulness for the heart may be taken as the right sternal border. The midsternal line supplies the boundary for relative dulness. The left limit of dulness corresponds to a perpen- dicular line drawn slightly without the apex-beat. The area of dulness will vary considerably in health. The younger the child, the further to the left will be located the border of cardiac dulness. This limit is best determined by percussing from a point in the anterior axillary line toward the right, in the fourth inter- space. The maximum transverse diameter of the heart normally in a radio- graph does not exceed half the transverse diameter of the chest at the same level. The heart may be said to be abnormally large when this proportion 404 THE PRACTICE OF PEDIATRICS is not maintained. The normal relationship of the heart to the chest is depicted in detail in Fig. 77.1 HEART MURMURS There are two gross divisions of heart murmurs: Organic or valvular, inorganic or f unctional. Organic murmurs are the result of a change in the heart structure due to a congenital malformation or to deformities resulting from dis- eased processes which produce a thickening, contraction, shortening, or narrowing of the valves involved. An enlargement of the orifice (e. g., the mitral or aortic orifice) may also cause a murmur due to the resulting incomplete closure of the valves. Regurgitant Murmur.—When the valves fail to close, a murmur is caused by the regurgitation of the blood back through the opening. If the valves are roughened, the intensity of the murmur is the greater. Stenotic Murmur.—When the blood is impeded in its passage through the heart as a result of a narrowing of the opening or roughening of the valves, a murmur of stenosis is the outcome. Organic heart murmurs are classified as follows, depending upon the time of their occurrence in the cardiac cycle: Systolic. Diastolic. Presystolic. From the association of the murmur with one or another of the different phases of the cardiac cycle we determine the location and nature of the lesion at hand. Location of Lesions.—In examination of the heart in order to locate a lesion by the murmur we must determine when it occurs in the cardiac cycle, its point of maximum intensity, and its area of diffusion. In children acquired valvular lesions will almost invariably be found to involve the left heart, the mitral valves being by far the most liable to disease. Mitral insufficiency takes first place in the order of frequency of valvular lesions. Mitral stenosis is evidently present in about 10 per cent, of the cases of insufficiency. Lesions of the aortic valves are, for- tunately, much rarer. The ratio of mitral to aortic disease is about 15 to 1. Table Demonstrating Location and Character of Lesions Based Upon the Adventitious Heart Sounds or Murmurs Systolic. Mitral regurgitation. Tricuspid regurgitation. Pulmonary stenosis. Aortic stenosis. Diastolic. Aortic regurgitation. Pulmonary regurgitation. Presystolic. Mitral stenosis. Pulmonary stenosis. Pulmonary stenosis occurs only as the result of congenital lesions, and tricuspid lesions in children are only observed very late in severe cardiac disease, as a result or accompaniment of right heart failure. In the absence of these etiologic conditions a systolic murmur in a child hartshorn and Perkins: x-Ray Studies of Cardiac Diseases in Children, New York Med. Jour, and Med. Record, March 7, 1923. HEART MURMURS 405 must, therefore, be attributed to mitral regurgitation or aortic stenosis. Moreover, for the reasons explained, a diastolic murmur means aortic regurgitation, and a presystolic murmur, mitral stenosis. Acquired lesions in children will, therefore, permit of the following grouping: Systolic. Mitral regurgitation. Aortic stenosis. Diastolic. Aortic regurgitation, Presystolic. Mitral stenosis. Keeping the time of the murmur in mind, we thus have a means of readily locating the lesions. Mitral regurgitation is due to shortening or adhesions of the mitral valves sufficient to prevent proper closure of the leaflets. The valvu- lar defects are the result of a previous acute or chronic endocarditis. The murmur of mitral regurgitation is heard loudest in the apex region, over the so-called mitral area. In children, because of the thin chest wall, this murmur has a wide transmission. The particular line of trans- mission is upward and to the left toward the axilla, and to the back, the sound here being loudest at the angle of the scapula and between the scapula and the vertebrae. Mitral stenosis (producing a presystolic murmur) is due to a narrow- ing of the mitral orifice as the result of adhesions which bind the valves together, and produce, in some instances, the so-called funnel or button- hole opening. The murmur is heard loudest slightly above and to the right of the apex-beat, in point of time preceding the systolic or first sound of the heart. Not infrequently this murmur merges into that produced by the mitral regurgitation, completely replacing the first sound of the heart. The area of diffusion is quite circumscribed. Mitral lesions which have existed for some time always give rise to compensatory hypertrophy, with corresponding displacement of the apex-beat to the left. This may readily be determined by palpation and percussion, showing the degree of cardiac enlargement. As a result of the contracted orifice or the roughened valve surfaces, vibrations are produced in the blood-stream which, when transmitted to the chest surface, produce a corresponding peculiar effect upon the pal- pating finger or hand of the examiner. This sign is known as a thrill. It must be carefully differentiated from the sensation communicated in some subjects by the thrust of a normal heart against a thin chest wall. Aortic stenosis produces a systolic murmur which is heard loudest over the sternum and the second left costal interspace; not over the second right interspace or to the right of the sternum, as in the case of adults. The murmur, which is usually harsh and grating in character, is widely transmitted in a lateral direction and also into the carotids of the neck. Autopsy usually shows the existence of adhesions between the semilunar valves. In comparatively few cases a thrill may be felt over the upper portion of the chest and the carotids. Illustrative Case.—In a girl patient eight years of age in whose heart stenosis and regurgitation were combined there was a most exceptional thrill over the dilated arch of the aorta and the carotids. 406 THE PRACTICE OF PEDIATRICS In aortic regurgitation the murmur is diastolic in time, and is heard not to the right of the sternum, but sharply against the left border, or over the extreme left of the sternum, on a level with the fourth costal cartilage. This murmur is usually associated with the obstructive mur- mur, and is due to a failure of the deformed valves to close. The area of diffusion is wide. There is always displacement of the apex-beat to the left. It is the condition of aortic regurgitation, pre-eminently, that causes visible pulsation of the carotids. In the child already referred to the throbbing was so pronounced that not only was the head and body shaken, but the mother, who slept with the patient, was kept awake by the vibration of the bed. In typical cases auscultation may detect a pistol shot sound if the stethoscope is placed over the bifurcation of the brachial artery or over the deep palmar arch, and inspection may reveal capillary pulsation be- neath the nails. Functional murmurs are most frequently encountered between the third and twelfth years and are not at all unusual in rapidly growing children of both sexes. The functional murmur in infants or very young children is not infrequently associated with anemia. This is not invariably the case, however, for a non-organic murmur at this age may be the result of a very severe illness or whooping-cough, causing a temporary dilatation. The functional murmur is systolic in time, and is heard loudest at or slightly above the apex, with a uniform, circumscribed area of diffusion which extends for only a few inches in any direction. In character the murmur is soft and blowing. It is not heard at the back. There is no associated hypertrophy or dilatation of the heart nor evidence of any stasis or dropsy. There is no accentuation of the second sound. The presence of a functional diastolic murmur in a child is practically unknown. Special Types of Functional Murmurs.—Venous Murmurs: In anemia the normal venous murmur heard over the great vessels above the clav- icle and posterior to the sternocleidomastoid muscle is intensified and exceeds its normal physiologic limits. The murmur is constant, although it may be accentuated when the patient stands with head inclined to the opposite side. The venous murmur is to be distinguished from the arterial murmur by the fact that the former is continuous and not syn- chronous with the heart-beat. Cardiorespiratory Murmur: This murmur deserves particular men- tion for the reason that it has a distinct entity. It may be heard in those cases in which the margin of the lung covers the heart. The mur- mur is usually systolic. It is heard best when the patient is standing and leaning forward, and at the end of inspiration is usually loudest. This murmur has no clinical significance, and is of interest only because it may be confused with other murmurs, functional or organic. Murmur During Development: As already noted, a functional mur- mur is not at all unusual in rapidly growing children. After Acute Illness: Inasmuch as the functional murmur which oc- casionally occurs with, and disappears after, an acute illness is in all respects similar to those that exist for several years and are later out- grown, it may be fair to assume that, in both instances, the same cause 407 FUNCTIONAL ABNORMALITIES IN CARDIAC RATE AND RHYTHM is operative, and that this factor, in all probability, is a moderate re- gurgitation, due perhaps to a dilatation of the mitral orifice preventing proper closure of the valves, a condition temporary in both types of cases, but in the one of longer duration than in the other. Etiology.—Although anemia probably constitutes the most frequent cause, yet functional murmurs are heard in apparently normal children, existing for a period of years and then disappearing. A temporary mur- mur will often be heard in boys after violent exercises or games of com- petition in which a great deal of physical work is involved. In girls the murmur may also result from excessive bicycle riding or prolonged rope jumping. In the spring of the year, after hard work at school, many girls, under careful examination, will show a slight systolic murmur. In our opinion many of these cases are due to a dilatation of the left heart, producing a wider auriculoventricular orifice than the valves can com- pletely close, with the result that there is a moderate amount of leak- age. This, in time, is corrected as the heart muscle regains its normal condition. Differential Diagnosis.—The chief point of aid in differentiating all murmurs, whether functional, acquired, or congenital, is the fact that in congenital and acquired heart disease there is a distinct lesion, and the murmur, as can be readily understood, is, therefore, constant. When, however, the murmur is due to causes related to muscular action or blood conditions, variations in posture or changes in the heart action dependent upon work will produce either a modification of the murmur or its com- plete disappearance. Even during a single examination a murmur of this nature may not always be the same. Illustrative Case.—A boy patient, aged six years, had a soft, blowing systolic mur- mur, which presented varying degrees of intensity, depending upon whether he lying down or sitting up or whether he w as quiet or exercising. The murmur appeared when he was two years old. He was always the picture of health. The murmur grad- ually became less each year, giving promise that when he was ten years old it would probably cease to exist. An older sister gave evidence of exactly the same condition, the murmur in her case disappearing at about the ninth or tenth year. The murmurs in these children were not anemic nor cardiorespiratory. Treatment.—The functional murmur requires no treatment. But the condition causing the murmur may require attention and determine treatment. FUNCTIONAL ABNORMALITIES IN CARDIAC RATE AND RHYTHM In addition to functional murmurs there are functional departures from the normal in cardiac dynamics. An outstanding example of the disorders of this type is afforded by the condition known as tachycardia, in which the heart action independently of the usual causes of increased rate is persistently very rapid. Bradycardia, or excessive slowness of the heart action, is less commonly encountered. The ordinary child, more or less highly emotional, rapidly growing, and subject to stress of varying nature, finds a ready reaction in the heart muscle and its nerve supply. The advent of puberty in both sexes is often suggested by the presence 408 THE PRACTICE OF PEDIATRICS of cardiac arhythmia. The existence of this condition is ordinarily dis- covered incidental to the examination of the chest for other possible disorders, as the patient is usually unaware of irregularity in the heart action. Tachycardia may be a manifestation of thyroid dysfunction. Such cases are typically those of overworked, overanxious school girls whose heart rate ranges from 120 to 140 during ordinary rest and is but slightly lessened during sleep. The heart in such instances impresses one as an organ that is driven. Under appropriate rest treatment and change the action returns to normal. The slight enlargement of the thyroid so common in girls at puberty gives rise in many of the cases of the type cited to the diagnosis of goiter. Such cases are by no means to be confused with those of Graves’ disease, although the functional cardiac cases may be potentially those of hyperthyroidism. Proof on this point is lacking. The fact remains that in experience with a vast amount of clinical material in private practice and hospital and consultation work the senior author has seen but 2 cases of actual Graves’ disease in children under fifteen years of age. Illustrative Cases.—Case 1.—A girl who came under observation for rapid heart action when four years old has had simple tachycardia for twelve years. Except for this symptom she has been perfectly well, and in spite of her usual pulse-rate of about 140, suffers no inconvenience. At first rest-treatment was attempted, without benefit. At the age of five years the patient was under the care of a physician expert in ductless gland treatment for several months, but without response. She was then referred to a heart specialist, who made an electrocardiographic examination and reported sinus arythmia, but stated that the heart in other respects was normal. He offered no sug- gestions other than those that had already failed. Different physicians, later consulted, were unable to achieve results, and the parents of the child, at length tired of the re- striction of her activity, discontinued all treatment. For the past seven or eight years the girl has led the life of the average well school child, riding bicycle, horseback riding, going bathing, and playing the usual children’s games, with a pulse-rate ranging about 140. She is not aware of the rapidity of the heart action and the family have given up thinking about it except perhaps when reminded that we would like to see the patient for our own information. Case 2.—Paroxysmal tachycardia in a boy eight years of age was marked by seizures decidedly distressing, at frequent intervals, requiring the use of codein for their control. The history suggested gastric hyperacidity and the gastric contents upon examination showed a total acidity of 90. Treatment given for this condition was followed by cessation of the tachycardia. Bradycardia in our experience has almost always been associated with a congenital lesion. Illustrative Case.—A boy patient never revealed a heart action over 40 during ob- servations covering the period from birth till the fourth year, at which time he passed from observation. At this time an electrocardiographic examination was suggested and refused. Heart-block occurs occasionally in childhood as a result of conditions interfering with the normal conductivity of the fibers of the bundle of His, notably in the cases of myocardial weakness of sudden development after diphtheria. Heart-block is also observed as one of the signs of ex- treme digitalization and may result from toxic* action of other drugs than digitalis. The digitalis effect may be temporarily beneficial and is transient if the administration of drug is promptly stopped. 409 CONGENITAL HEART DISEASE Fainting attacks are of frequent occurrence as a result of nervous dis- order and may occur independently of cardiac weakness. Auricular fibrillation is rarely noted in children. The study of cardiac disease has been greatly enhanced during the past two decades by the development of electrocardiography. To this science Lewis, Mackenzie, Einthoven, and Williams have contributed most extensively. Under conditions that suggest cardiac disease or derangement it is our duty to exclude the existence of organic cardiac disease, and when this has been done it is equally our duty to find defects apart from the heart that may account for the altered function, and then leave the organ to take care of itself. This in the great majority of cases it will do. CONGENITAL HEART DISEASE In congenital heart disease there is a fundamental structural fault. The heart in one or more respects is anatomically imperfect. Etiology.—Many cases are directly traceable to defective develop- ment in the embryonic cardiovascular system, and to understand well the anomalies found at autopsy one must review the subject of the fetal circulation. Septal defects in the heart and persistence of the patent ductus arterioshs and various forms of hypoplasia of the great vessels illustrate the lack of normal completion in cardiovascular development. Other abnormalities are ascribed to a fetal endocarditis. Constitutional disease in one or both parents may be a causative factor producing the endocarditis. The frequent association of congenital heart defects with other defects in development is noteworthy, and particularly so is the frequent existence of cardiac abnormality in Mongolian idiots. Varieties of Congenital Cardiac Disease.—The following tabulations based in part on the statistics of Abbott1 are quoted from Griffith’s work.2 Classification of Forms of Congenital Cardiac Disease 1.

This, through interference with the blood-current, prevents a closure of the auricular or ventricular septum. Fig. 78.—Clubbed fingers in congenital heart disease, Cases are occasionally seen, however, in which the defect in one or other of the septa exists without atresia or stenosis at the pulmonary orifice. Enlargement of the heart is the rule. Usually the right heart will be found particularly involved. The above conditions represent some of the more common abnor- malities. One who observes many autopsies upon children will have abundant opportunity to verify the above statements and to see other abnormalities which are of academic interest only. Symptomatology.—Congenital heart disease is sometimes suggested by the appearance of the patient. There may be cyanosis, which is ob- served only when the child cries or strains, or the patient may be a “blue baby,” in which case the cyanosis is permanent and of such a degree as to make the diagnosis positive without further aid than inspection. CONGENITAL HEART DISEASE 411 In far the greater number of cases the defect is discovered upon routine examination with no external sign whatsoever indicating that a lesion exists. Classification of Lesions on Clinical Examination.—-It is a hopeless task to attempt to classify a congenital lesion according to the nature, maximum intensity, or transmission of the murmur. Even after the signs have evoked a common diagnosis from several observers autopsy may show conditions not flattering to the diagnostic acumen of the examiner. In general, the following points may be borne in mind, in an attempt to diagnose the existing lesion in a given case: Patent interventricular septum gives rise to a systolic murmur maxi- mum at about the fourth left interspace near the sternum, not transmitted to the neck, and unaccompanied by thrill and cyanosis. Pulmonic stenosis typically produces a systolic murmur heard over the second left interspace near the sternum and accompanied by a definite thrill. Cyanosis, enlargement of the right heart, and clubbing of the finger-tips are noteworthy. Patent ductus arteriosus gives rise to a loud prolonged “humming- top” or “coffee mill” murmur heard in both phases of the cardiac cycle over the entire precordium and transmitted upward in the carotids. This condition often occasions little physiologic difficulty and might go on unrecognized were the heart not examined by the ear. Patent foramen ovale, patent interventricular septum, and patent ductus arteriosus are compensatory in the presence of pulmonic stenosis. Cyanosis and cardiac enlargement without audible murmur may be due to complete atresia or hypoplasia of the pulmonary artery. Diagnosis in Infants and Very Young Children.—The most valuable diagnostic sign is a pronounced cardiac murmur in a child under eighteen months of age. Children before this period of life rarely have rheu- matism, which is the cause of endocardial lesions in over 95 per cent, of the cases. The absence of cyanosis is no evidence against the diagnosis of a congenital lesion, as a great majority of the cases have not shown this symptom. On the other hand, there may be a marked degree of cyanosis and not the slightest trace of a murmur. At autopsy such a case showed an entire absence of the ventricular septum. First, then, the age of the child is strongly suggestive as to whether the condition is due to a congenital abnormality or acquired disease. If the patient is under eighteen months of age or even under twTo years, the lesion is, in all probability, congenital. Second in importance is to be noted the character of the murmur, which is usually systolic and of a very loud, rasping character, heard loudest in the third or fourth left intercostal space with a very wide area of diffusion. Many of these murmurs may be heard over the entire thorax, both anteriorly and posteriorly. Differential Diagnosis in Infants.—At this period of life the murmur of congenital heart disease has to be differentiated from the murmur found in anemia. Not all congenital murmurs are as characteristic as above described. They may lack the element of loudness and harshness and be soft and blowing in character. This, however, is of very infrequent 412 THE PRACTICE OF PEDIATRICS occurrence. In such an event a differential diagnosis between a con- genital cardiac lesion and a murmur due to anemia is most difficult, for the anemic murmur is systolic in time, is heard loudest over the base, and has a fairly evenly distributed area of diffusion in all directions. In such cases the blood examination is of decided service. In con- genital heart disease there is almost constantly a very extreme poly- cythemia with high hemoglobin percentage and specific gravity, and a moderate increase in the white cells (Wood). Murmurs Due to a Definite Lesion.—These are constant and vary little under different states. Whether the patient is at exercise, at rest, sitting, standing, or lying down, the murmurs are invariably present and vary only in intensity. This fact is a valuable aid in differentiation. The Functional Murmur.—The chief characteristic of the functional murmur is the inconstancy of the sound, now loud, now weak. Not in- frequently these murmurs disappear under stress and reappear when the stress is removed. They may disappear or become very faint with the patient recumbent, and reappear upon the return to the erect position. A relaxed heart muscle might be a cause of some of these cases. The anemic murmur typically changes upon change in position of the patient, and during exercise it is inconstant. Diagnosis and Differential Diagnosis in Older Children.—In children after the second year the differential diagnosis may be more difficult. It is to be remembered that in cases in which a congenital murmur is well marked at this period of life there will usually be other signs that may aid us in our judgment. is present in a larger proportion of the older patients than of the very young. This is to be explained by the fact that the child when very young calls upon the heart to a com- paratively small extent. With the assumption of active play and with running, stair-climbing, and stress of any nature, the defective heart fails to meet the extra demands, and cyanosis, clubbed fingers (Fig. 78), and shortness of breath develop. At this age also the question of anemia and developmental conditions arises. Repeatedly patients are seen who show no inconvenience whatever until this more active period of life is reached. Murmur After Illness.—The murmur of congenital disease is also to be differentiated from other functional murmurs than those of anemia (p. 406), which are practically all systolic in time and have a wide area of diffusion. These functional murmurs often occur during, or particularly after, severe illnesses, such as pneumonia or typhoid fever, when the heart has been severely taxed. With such a murmur there is no accentua- tion of the second sound, no accompanying dropsy or cardiac enlarge- ment, and the murmur is inconstant and variable, being influenced by the activity of the heart and the position of the patient. Prognosis.—The future of the child with the congenitally defective heart is very uncertain. A very few of these patients go on to the adult period of life and suffer no inconvenience. In by far the larger number of cases, however, the approach of the runabout and active period (if the child survives to this time), with the extra demand upon the organ that this age necessitates, results in failure of compensation, and dilatation, followed by the usual train of symptoms peculiar to right heart failure. PERICARDITIS 413 Illustrative Case.—A girl with congenital heart disease developed several attacks of angina and cyanosis at the thirtieth month. This continued at rather infrequent intervals for a year, when she died in an attack. PERICARDITIS Etiology.—Inflammation of the pericardium is usually associated with endocarditis of rheumatic origin. No period of life appears to be exempt. Our youngest patient was six months of age. The disease occurs most frequently between the third and the twelfth years. Cases have been reported by different authors as occurring in fetal life. As the result of an infection the disease occurs not only in association with rheumatism but also as a result of the invasion of pathogenic bacteria carried through the blood-stream or by the lymph from other portions of the body. Before the third year pericarditis is associated with pneumonia and empyema with greater frequency than with any other disease. Bacteriology.—The organism most often found in the serofibrinous or purulent exudate is the pneumococcus, a fact which is explained by the frequency of pulmonary lesions as the primary source of the infection in 70 to 90 per cent, of these cases. The streptococcus or the Staphylococcus aureus may be present; and very rarely Bacillus influenzae or the gonococcus has been found in the course of septicemia due to these bacteria. The tubercle bacillus, as the cause of fibrinous or purulent pericarditis in chil- dren, is almost unknown. Tuberculosis is more apt to involve the ex- ternal surface of the sac owing to possible extension of tuberculosis of the lung. Poynton has found the so-called “diplococcus of rheumatism” in the plastic exudate of pericarditis complicating rheumatism. Pathology.—Pericarditis possesses as wide possibilities as pleuritis, and the pathologic processes are quite similar. Thus, there may be only simple dryness of the lining of the pericardial sac, or a complete filling of the sac with serous or purulent fluid. Over the heart and the enveloping membrane only thin layers of fibrin may form; or the heart and peri- cardium may become firmly bound together by layers and bands of fibrinous exudate. Autopsies in purulent cases often show the heart wrapped in the meshy fibrinous exudate to such a degree that the muscle surface cannot be seen, while the inner surface of the pericardium is lined with a granular exudate and the intervening space is filled with fluid serum or pus. On showing postgraduate students such specimens the senior author has witnessed complete failure of the entire class to recognize the organ before them, so great has been the change from the normal appearance. Symptoms.—Pericarditis is a disease which stands out peculiarly because of the wide range of the possible symptoms. Thus a case of purulent pericarditis may run its course under the observation of excel- lent clinicians and not be recognized until the autopsy, or may produce symptoms of the greatest urgency and occasion intense distress to the patient. It is, therefore, impossible to lay down a symptomatology for the disease that will apply to all cases. Pericarditis is quite possibly more frequently overlooked by clinicians than any other disease. Cyanosis is present. The expression is anxious. In urgent cases a 414 THE PRACTICE OF PEDIATRICS prominent symptom is extreme restlessness. Discomfort, pain, and a feeling of tension over the precordium are at times complained of. In other cases with apparently quite pronounced lesions there is little or no discomfort. An important symptom indicating pericarditis is rapid respiration. Not only is the breathing rapid, as in pneumonia, but it is fairly charac- teristic in that the respirations are guarded. The patient appears to have his mind centered on breathing. Carefully guarded inspiration is taken and careful expiration is carried out. At the same time the respira- tion is hurried and short, although not precipitate. This cautious breath- ing is due to the feeling of decided discomfort, constriction, and even pain which accompanies the chest expansion. The respiration is some- what similar to that of acute pleurisy. The individual is not sure that he will be able to complete respiration, and perhaps feels obliged to cut it short. The very rapid heart, action is the most reliable symptom of the dis- ease, often exceeding in apparent severity all the other symptoms. We have repeatedly seen patients from eight to ten years of age with a temperature rise to only 100° F., with a pulse-rate from 130 to 150 or higher. Physical Signs.—The first proof of pericardial inflammation is a rub- bing, grating sound, known as the pericardial friction sound, heard over or slightly above the apex of the heart. The sound has a double quality and is heard both at systole and diastole, or perhaps only with systole, and in well-marked cases will be transmitted to the finger on palpation. Wherever heard the sound is distinctly localized. In cases of effusion in older children there may be bulging of the interspaces. With the appear- ance of considerable fluid the friction sounds cease, but return when the fluid is absorbed. In cases in which the friction is questionable or indis- tinct, it will be accentuated by having the child lean forward in a sitting position. Percussion.—When fluid in considerable amount is present, the area of cardiac dulness will be increased, the apex-beat will be difficult to determine, and the normal heart sounds will become weakened. Oblitera- tion of the cardiohepatic angle may be noted, although the findings of Morris and Little1 indicated that in pericardial effusion this angle typically is acute. In a fatal case in a six-year-old boy the apex-beat was not demonstrable, and the heart sounds could scarcely be heard. It has not been our observation that the apex-beat is displaced up- ward, as is claimed is the case in adults. With the presence of consider- able fluid—over 2 ounces in a child from three to five years of age—the dulness will be increased to the left and upward. Shifting dulness, if found on change from the recumbent to the erect sitting position, is most diagnostic. With the larger effusion occurring in the boy above mentioned, the dulness extended to the right nipple and 1 inch outside of the left nipple. 1 Amer. Jour. Med. Sciences, November, 1923. 415 PERICARDITIS The amount of fluid is difficult to determine in any case, and particu- larly so when endocarditis and myocarditis coexist, with accompanying hypertrophy and dilatation. Diagnosis.—The x-ray is essential in doubtful cases. Differentiation between cardiac dilatation without effusion, pericarditis with effusion, and left pleural effusion is not at all times easy. In every case of acute heart disease in a child the physician should be particularly careful to investigate the cause of exceptional rapidity of breathing and pulse-rate. Prognosis.—The prognosis in rheumatic cases is good if proper treat- ment can be followed. We are dealing with a disease in which the man- agement of the case determines to a large degree the outcome. Just how complete a recovery is made in the so-called recovery cases is difficult to determine, as there must be, in every case, adhesions between the heart and the pericardial sac. A condition known as adherent pericardium (p. 429) may be the outcome. The purulent cases, with so-called malig- nant endocarditis, have, with rare exceptions, been fatal. The duration of the acute cases of rheumatic origin varies from a few to a considerable number of weeks. Treatment.—In considering the treatment we may divide cases of the disease into two groups—those of rheumatic origin and those due to the invasion of well-known pathogenic organisms. In the rheumatic cases the sick-room management and the diet are the same as in the treatment of endocarditis (p. 419). In addition to the management pur- sued in endocarditis, additional symptomatic treatment is required. For controlling excessive rapidity of the heart the tinctures of digitalis and aconite may be of much service. To a child eight months to three years of age \ drop of tincture of aconite and 1 drop of tincture of digitalis may be given at two-hour intervals, but not to exceed six doses in the twenty-four hours. After the third year 1 drop of the tincture of aconite and 3 drops of the tincture of digitalis may be given at two-hour intervals— six doses in the twenty-four hours. For the extreme restlessness which often exists codein or paregoric may be given. For a child under two years of age paregoric is safer. It may be given in doses of from 10 to 20 drops and repeated when indi- cated at intervals of two or three hours. Older chlidren—between the second and sixth years—should be given codein in doses of from 1/10 to 1/6 grain. After the sixth year 1/4 grain may be given, to be repeated at three-hour intervals or less frequently, not more than three doses being given in twenty-four hours. As soon as the diagnosis is made, if the case is of rheumatic origin, it is advisable to begin giving salicylate of soda with a view to prevention of effusion into the pericardial sac. The belief of various clinicians that rheumatic carditis is unaffected by salicylates does not justify neglect in the use of the agent acknowledged to be specific for rheumatism in gen- eral. To children under three years 14 to 20 grains of salicylate of soda should be given daily, with twice the amount of bicarbonate of soda. As the salicylate may cause some gastric disturbance, it should never be given when the stomach is empty except in milk or with some other food; 4 grains is as much as should be given at one time. After the third 416 THE PRACTICE OF PEDIATRICS year from 20 to 30 grains may be given. At the tenth year 40 grains may be given daily in divided doses, always in solution, under the same precautions as to giving the drug after meals. It is impossible and entirely unnecessary in this country to give the large doses of the salicylate which are given abroad. For delicate children and those by whom the salicylate is not well tolerated, aspirin may be substituted; or the salicylate may be given by the bowel in doses of 15 grains at a time. The medicine should be diluted with at least 4 ounces of water and introduced through a rectal tube which has been inserted at least 9 inches. This procedure should be carried out not oftener than twice daily, and should be immediately preceded by irrigation of the large intestine. In the comparatively infrequent cases in which 'pericarditis complicates one of the infectious diseases, the salicylate treatment is not to be advised unless there is some suspicion of rheumatism. The other methods sug- gested are to be carried out with the hope that the disease may be controlled. In this type of case the ice-bag is particularly serviceable (p. 420). In the event of effusion so excessive as to interfere with the heart action, producing orthopnea and cyanosis, with feeble, irregular pulse, operation on the pericardium, such as aspiration or incision and drainage, is to be considered, although in the few operative cases which we have seen we have not been impressed with the great usefulness of this treatment. On the other hand, we have seen cases, in which there was an excessive accumulation of fluid, recover under less radical measures. The Purulent Type.—When it becomes evident that pus is present in the sac, incision and drainage may be attempted, as the case will surely be fatal if the usual methods are pursued. In this type the blood shows a very high white cell count with very high polynucleosis. ACUTE ENDOCARDITIS Acute endocarditis is an inflammation of the endocardium or lining membrane of the heart. Probably in all cases showing even a moderate degree of severity there is involvement of the adjacent heart muscle, so that when there is an endocarditis there is a myocarditis as well, although the latter may be of little moment. Pericarditis has been a complication in about 5 per cent, of our cases. In the great majority of instances endo- carditis is to be looked upon as a manifestation and not a complication of rheumatism. Etiology.—Endocarditis is present in a considerable proportion of cases of chorea, the statistics of various authors varying from 6 to 55 per cent. Both the chorea and the endocarditis are active manifesta- tions of rheumatism. In our own experience endocarditis has been pres- ent in not over 20 per cent, of the cases of chorea. Endocarditis occurs as a complication of scarlet fever, diphtheria, measles, and tonsillitis. In fact, there are few diseases of bacterial origin with which it has not at some time been associated. In 2 cases it was a complication of grip. Age.—It is unusual to find endocarditis in children under three years of age. Few cases are seen between the third and fifth years. The period of greatest susceptibility is between the fifth and the twelfth years. ACUTE ENDOCARDITIS 417 Family susceptibility to rheumatism, chorea, and endocarditis is note- worthy and has been emphasized in a study of 100 families by St. Law- rence.1 Bacteriology.—The vegetative forms of endocarditis are more fre- quently due to rheumatism than to any other infectious disease. Poynton and Payne demonstrated a “diploeoccus rheumaticus” in the vegetations on the heart valves. The bacteria are said to be found readily only in the early stage of the endocarditis, tending to disappear in the later course of the disease. The identity of the causative organism in rheumatic endocarditis is, however, still not universally granted. “The disease would appear to be a modified septicopyemia.”2 Acute ulcerative or septic endocarditis is more often a secondary than a primary condition, and is caused by the localization on the heart valves of bacteria from the blood-stream. The bacteria causing the primary infection are present in the valvular ulcers. Streptococci, staph- ylococci, pneumococci, gonococci, typhoid bacilli, colon bacilli, influenza bacilli, and diphtheria bacilli have been found. In cases of malignant endocarditis the causative organism (not infre- quently the Streptococcus viridans, as in adult cases) may be found by blood-culture. In chronic endocarditis no bacteria are demonstrable in the endo- cardial lesions. Pathology.—Inflammation of the membrane lining the heart affects chiefly the valves; and most frequently those guarding the mitral and aortic orifices. The latter fact has been explained by a theory that bac- terial development is better favored by the fresh arterial blood of the left ventricle than by the venous blood (of low oxygen content) present in the right heart. The margins of the affected cusps are thickened and covered with small masses of necrotic tissue, fibrin, red corpuscles, leukocytes, pro- liferating endothelial cells, and bacteria. The chordae tendineae are frequently involved and undergo shortening, thickening, and a certain amount of fusion. In the myocardium perivascular groups of cells are to be found in concentric layers. These foci, known as Aschoff’s bodies, may ultimately be incorporated in a process of fibrosis. In cases of mild infection the seat of the inflammation is at the base of the valves in the heart muscle and there is left no permanent lesion. More frequently, however, when the acute inflammation subsides the valves undergo considerable cicatrization and contraction, and exist thenceforth as deformed and more or less inefficient structures. In the severe forms of the disease, commonly termed “malignant en- docarditis,” destructive effects are much more marked, and ulceration of the mural endocardium may occur. In such cases emboli frequently become detached from the friable vegetations on the valves, and produce infarcts and abscesses in such remote organs as the brain, spleen, and kidney. The usual sources of infection are wounds of the skin and mucous 1 Jour. Amer. Med. Assoc., December 16, 1922. 2 Reid, The Heart in Modern Practice, 1923, p. 97. 418 THE PRACTICE OF PEDIATRICS membrane, and inflammation of the alimentary, pulmonary, and genito- urinary tracts. Prominent in this category are diseased tonsils and teeth. Attacks of “simple” acute endocarditis may easily render the heart more susceptible to an infection of the malignant type. Symptomatology.—By far the majority of cases of endocarditis present no symptoms whatever. Hundreds of these cases are overlooked because of this peculiarity of the disease, and because writers lay great stress upon a symptomatology of prostration, high temperature, and severity in general, that may occur in one out of 10 cases, the result being that 9 are overlooked. A large majority of the cases of endocarditis coming under our observation (mild acute endocarditis, not chronic valvular disease) have been discovered in the routine examination of the patient, and not because anything in the case had suggested the heart as a factor in the illness. Every physician who does considerable clinical work sees patients with valvular defects of long standing, who have no knowl- edge whatever that a heart lesion has existed. Clinicians who examine for life insurance will particularly appreciate the force of the above state- ment. We have repeatedly seen cases develop during or after tonsillitis in children with a rheumatic tendency, the endocarditis being the active manifestation of the rheumatism. Illustrative Case.—A boy six years of age had a slight pain in his knee, which caused a limp. He had just recovered from a mild tonsillitis. In the routine examination acute endocarditis was found, involving both the mitral and aortic valves. The boy made a complete recovery. There are doubtless many cases of endocarditis which pass unrecog- nized and terminate in recovery. When acute symptoms are present, we find fever which presents wide variations—100° to 105° F.—depending upon the severity of the in- fection. The height of the temperature is usually a reliable indication of the gravity of the illness. With the high temperature there is increased heart action ranging from 110 to 140. If the action is irregular, myocar- ditis also may be suspected. Pain over the precordium and shortness of breath are usually present. Diagnosis.—The symptoms alone may be sufficiently pronounced to suggest the existence of endocarditis. It is by the physical signs, however, that suspicion is verified and the diagnosis made possible. Inspection, if it reveals anything abnormal, will show an excessive action of the heart, producing an undulating motion of the cardiac area, with visible apex-beat. Palpation confirms the existence of this overaction of the heart and may detect a thrill corresponding to the murmur found on auscultation. Percussion may reveal cardiac enlargement. The left ventricle be- comes dilated early in the severe cases. Auscultation will reveal either a murmur (p. 404) or a combination of murmurs. In character the murmur may be soft and blowing, or harsh, rough, and grating. It may be systolic, diastolic, or presystolic; or it may be double, presystolic and systolic, or diastolic and systolic. The fact that the left side of the heart is always involved simplifies materially the localization of the lesion. ACUTE ENDOCARDITIS 419 If due to mitral regurgitation, the murmur is usually soft and blow- ing in character, heard loudest at the apex, transmitted to the left axilla, and plainly heard between the scapula and the spine. In mitral stenosis the murmur is presystolic in time, and is heard loudest just above the site of the apex-beat. This murmur is not trans- mitted elsewhere, and is accompanied by a thrill (p. 405). When there is combined mitral stenosis and regurgitation the sys- tolic murmur folloAvs immediately upon, the presystolic, making a pro- longed murmur which completely obliterates the first heart sound. Aortic stenosis produces a systolic murmur, heard loudest at the second interspace, over the middle of the sternum, or at its immediate right border, and transmitted upward to the carotids. In aortic regurgitation the murmur is diastolic in time and is usually heard loudest over the second and third left interspaces. Differential Diagnosis.—Endocarditis may be confused with tem- porary functional disturbances of the heart, giving rise to functional murmurs (p. 406). This statement, of course, applies only to mitral disease. After many disorders in children in which the heart has been severely taxed, a soft, blowing, systolic murmur develops. This mur- mur, however, is inconstant, changes more or less, or disappears upon change in the position of the patient, and, most important of all, has no line of transmission and is not heard at the back. After a few days or weeks, providing proper management is carried out, such murmurs disappear. Prognosis.—The outlook, in a great majority of cases of endocardi- tis, is favorable for a complete recovery. In other cases, even under the best of management, the patient, after recovery from the acute disease, is left with crippled valves. When there is a very severe infection of the so-called malignant type the outlook is most unfavorable. Illustrative Case.—A boy seven years of age died within forty-eight hours from the onset of the heart involvement. A considerable number of similar fatal cases have been encountered in consultation work. The inflammation in such cases usually develops rapidly into a pan- carditis, the heart muscle, the pericardium, and the endocardium all becoming rapidly involved, with resulting dilatation of the heart, which is often extreme. In such cases there is usually a general septicemia. Treatment.—Rest in Bed.—Whatever the nature of the infection, and whether the disease is mild or severe, one rule—that regarding quiet and rest—must be consistently followed. The child must remain in a recumbent position in bed, the bed-pan being used to receive the excreta. The use of the arms and the hands should be discouraged, particularly early in the attack, as it is at this time that the greatest damage is done to the heart. Reaching from the bed to the floor or to the table or chairs should be forbidden. The heart must be given as little work to do as possible. Prolonged Inactivity.—In both pericarditis and endocarditis absence of stress of any nature should be secured until every evidence of the 420 THE PRACTICE OF PEDIATRICS disease has disappeared, or at least until the heart becomes regular, and its rate, under a test of moderate exercise, approximates the normal. Ilustrative Case.—The longest period we have kept a patient recumbent was six months. This patient is now a young man, and all that remains of his very extensive endocarditis and pericarditis, comprising three distinct attacks, is a slight mitral re- gurgitant murmur with full compensation. Every patient is kept off the feet for at least six weeks, and several have not been allowed to take a step within three to six months. Diet.—The diet should consist largely of fluids, administered in com- paratively small amounts, at shorter intervals than in health. The bowels should move once daily. If a laxative is necessary, a saline should be given. A Seidlitz powder or magnesium citrate is usually effective. Distention of the stomach, whether by gas or by food, causes pressure on the heart and increases its labor. It is a good custom, in these cases, to give five feedings in twenty-four hours, and not more than 8 ounces at a feeding. Four ounces of milk and 4 ounces of gruel, with zwieback or toast, constitute the usual feeding. In order to vary the diet a weaker gruel, No. 1 (p. 94), flavored with an ounce or two of chicken or mutton broth, may be given; or a gruel of the same strength may be given plain, with sufficient salt to make it palatable. If the milk is well borne, it may be increased until 1 quart is taken daily. The enforcement of a strict milk diet is a mistake. The child very soon tires of it, digestion is im- paired, and nutrition is correspondingly faulty. As improvement becomes apparent eggs, bread and butter, stewed fruit, poultry, fish, and plain puddings may be added to the diet. In order to facilitate freer feeding the number of meals should be reduced. The Ice-bag.—A screw-top ice-bag half-filled with chopped ice should be placed over the heart, and, if possible, kept on continuously. Children frequently become restless and irritable under too constant application of the ice, and in such instances it may be left off occasionally for half an hour or an hour. Gilman and White1 have shown that “the greatest effectiveness might be achieved by alternating half-hour periods.” A most reprehensible practice is the overfilling of the ice-bag to such a degree that its weight is a direct physical burden upon the heart. Drugs.—In endocarditis following diphtheria or the exanthemata drugs are of little benefit. Salicylate of soda seems to have no bene- ficial effect upon these patients. For excessive rapidity of the heart action digitalis is more effective than any other drug. To children from five to ten years of age 3 to 6 drops may be given at intervals of from three to six hours. When a more rapid effect is desired the Eggleston method and dosage may be followed (p. 428). If there is much excitability and restlessness, i grain of codein or 8 grains of sodium bromid may be given at sufficiently frequent intervals to control the condition. While every case of non-rheumatic endo- carditis presents possibilities of serious and permanent damage to the heart, not every case, by any means, is of sufficient severity to demand other treatment than the ice-bag, rest, and an easily digested diet. It is often the milder cases that occasion the gravest sequelae, on account 1 Jour. Amer. Med. Assoc., September 1, 1923, p. 748. ACUTE ENDOCAEDITIS 421 of the lack of objective symptoms, and the liberties given the child by parents, who are with difficulty convinced of the gravity of the disease. Antirheumatic Treatment.—Every case of endocarditis under our care, which is not directly associated with one of the specific infectious diseases, is considered and treated as though it were a case of rheumatism, owing to the exceeding frequency of this form of infection. Sodium salicylate and sodium bicarbonate are early brought into use. To a child between five and ten years of age from 3 to 5 grains of sodium salicylate with an equal quantity of sodium bicarbonate are given after each feed- ing five times daily. The medicine may be given in capsules or in solu- tion. If the sodium salicylate is not well borne by the stomach, the equiv- alent dosage of aspirin or oil of wintergreen may be given. The salicylate should be continued with occasional intermissions of a day or two until such urgent symptoms as fever, rapid heart-rate, and dyspnea have sub- sided. The dosage should then be varied, 10 grains being given daily for five days out of fifteen. A child who has recovered from rheumatic endocarcitis should be kept under close observation, and the parents should be warned as to the possibilities of a second attack. Illustrative Cases.—Case 1.—In a private case, in spite of antirheumatic treatment, during the intervals four distinct attacks occurred during five years. Case 2.—A dispensary patient at the New York Polyclinic had his first attack when four years of age. So prominent was his rheumatic tendency that during the next four years, in spite of active antirheumatic treatment and a careful diet in the intervals, he had eight distinct attacks of endocarditis, and died from the heart in- volvement in his eighth year. There were other manifestations of rheumatism in his case, and his family on both sides for several generations had been markedly rheumatic. Convalescence.—When the pulse-beat is reduced to 100, which is not to be expected earlier than the fourth week, the patient may be allowed to sit in a reclining chair. Previous to this, while still in bed, he may be gradually accustomed to elevation of the head by the addi- tion of an extra pillow for an hour or more daily. Greater freedom is permitted when it is found that the patient can be indulged and the heart- rate still be kept below 100. Recurrence.—Inasmuch as a recurrence is very probable, the patient, even while in apparent health, should have the benefit of a restricted diet, being allowed red meat but twice a week and a minimum amount of cane-sugar. During five days out of each month he should receive 10 grains of sodium salicylate and 10 grains of sodium bicarbonate daily. This scheme of medication should be continued for at least two years, and much longer if the patient shows any further rheumatic manifesta- tion, such as pains in the legs, or repeated attacks of tonsillitis. The length of time during which absolute rest in bed is to be enjoined depends on the severity of the case. This time in most primary cases is from six weeks to three months. Illustrative Case.—In the case of a boy who had had a very severe second attack, walking was not allowed for six months, the patient using a wheel-chair instead. In a case of moderate severity in which the fever may have continued for only a week or ten days, the heart action, which has ranged from 140 422 THE PRACTICE OF PEDIATRICS to 160, gradually becomes less frequent. The rapidity of the heart rate is the best guide in deciding when walking shall be permitted, and a safe rule is to permit increase in activity only when the pulse is consistently below 110. Every child who has had acute endocarditis should have the tonsils enucleated. Dental foci of infection must likewise be eradicated. Conclusion.—The above scheme of management may seem unneces- sarily severe, but we must remember the importance of the heart in the economy, and see to it that if the patient cannot have a perfectly sound heart, it shall be damaged as little as possible. The treatment thus comprises the observance of every precaution that will tend toward the best possible outcome, no matter how drastic may be the requirements. MYOCARDITIS Myocarditis of mild degree is a frequent accompaniment of inflam- matory disease of the pericardium and endocardium. The most severe cases, however, may not be of this type. Etiology.—Acute parenchymatous myocarditis may follow various processes, but is most often due to the activity of the toxin of the pneu- mococcus, the typhoid bacillus, or the diphtheria bacillus. Inflammation of the endocardium or the pericardium may extend to the myocardium. Further references to the causation of this disease are included in the discussion of the pathology. Pathology.—Classifications of myocarditis are more or less artificial. Acute and chronic forms and parenchymatous and interstitial types of inflammation are recognized. Acute parenchymatous myocarditis usually results from an acute in- fection or toxemia, such as diphtheria, typhoid, or scarlet fever. The heart muscle is pale in color, soft, and somewhat friable. The heart itself may be dilated. Microscopically, the muscle-cells show granular, hyaline, and fatty degenerative changes, and frequently contain vacuoles; the nuclei stain imperfectly. In the interstitial tissue polynuclear and lymphocytic infiltration and even some extravasation of blood may occur, these conditions being most marked in the neighborhood of blood-vessels. The reparative process is largely that of replacement fibrosis, a pro- ductive inflammation terminating in the substitution of fibrous con- nective tissue for the degenerated cells. Development of new muscle tissue also occurs. This, however, is probably brought about by simple hypertrophy of undegenerated muscle-fibers, rather than by true hyper- plasia of these elements. Acute suppurative myocarditis may result directly from an abscess in the mediastinum or a purulent pericarditis, but is more frequently due to a general pyemia caused by the pneumococcus, streptococcus, staphylococcus, or gonococcus. The wall of the heart contains miliary pus foci and small extravasations of blood. Microscopic examination shows the vessels to be filled with embolic products, and surrounded by the small hemorrhagic areas and collections of pus-cells already des- cribed. The process, although essentially one of interstitial inflamma- tion, is regularly accompanied by considerable degeneration of the muscle- MYOCARDITIS 423 fibers. In the rare cases when recovery from suppurative myocarditis occurs, the defects in the heart are remedied by fibrous tissue. Chronic interstitial myocarditis in childhood is a productive repara- tive process, usually secondary to inflammation of the acute type. The development of this condition to compensate for atrophy of the heart musculature caused by defective blood-supply through partially occluded coronary arteries is essentially a change of later life. When due to syphilis, chronic myocarditis in children is usually accompanied by endarteritis. Gummata are rare, although Treponema pallidum may be demonstrated in the myocardium. Symptoms.—The most characteristic early sign of myocarditis in a child is a persistently irregular pulse, with or without a tendency to in- creased rapidity. It is not at all essential that the pulse be rapid—in fact, it is not at all unusual for it to be slower than normal. When such irregularity occurs after an acute disease, and particularly when there are occasional periods of cyanosis, myocarditis may be expected. It is often difficult to judge accurately of the heart’s action when the child is awake, because of the excitement and possible resistance which the presence of the physician may occasion. For this reason, in suspected cases, the child should be examined, if possible, when asleep. When the child develops the above symptoms he should be watched with the greatest solicitude, as the more urgent symptoms of pallor, marked cyanosis, and syncope may occur at any moment. The pulse becomes very irregular and thready, or it may be lost entirely at the wrist, the patient presenting a picture of impending dissolution. In pneumonia, in virulent cases of diphtheria, and in the exanthemata the symptoms of acute myocarditis are those of early heart failure and are of grave significance. The pulse becomes rapid and irregular, cyanosis is constant, and the respiration is increasingly difficult because of the sense of pressure and constriction in the cardiac region. In diphtheria a sudden extreme drop in the rate of a previously rapid heart is of serious import and may be due to heart-block (p. 408). Diagnosis.—The diagnosis of myocarditis is based upon the irregularity of the pulse following an acute infectious disease, and upon the sudden attacks of cyanosis and collapse. Auscultation is of value only in dem- onstrating the weakness and indefiniteness of the first sound. Treatment.—Rest in Bed.—When the condition follows even a mild attack of one of the infectious diseases, the invariable rule of absolute heart rest, which is by far the most important feature of the treatment, must be insisted upon. The patient, whether in hospital or in a private home, should not be allowed to sit up or even to raise his head from the pillow; a trained nurse should remain constantly in attendance, so that the child may be read to or otherwise entertained while physical exertion is prevented. He may be permitted to use his arms, to play with simple light toys, but all other exertion must be prohibited. Aside from provis- ions for the recumbent position, quiet, a daily bowel evacuation, and easily digested food given in small quantities, little treatment is required. It is important to keep the stomach free from distention with either gas or food. Small quantities of nourishment administered at frequent intervals are preferable to large quantities given at the usual mealtime. 424 THE PRACTICE OF PEDIATRICS Drugs.—In the more severe cases with cyanosis and dyspnea a hy- podermic containing strychnin, 1/50 grain, and digitalin, 1/100 grain, should be kept constantly at the bedside. In one case following scarlet fever so urgent were the symptoms that three phys- icians were engaged for several days, each being for eight hours daily at the bedside, in addition to the two trained nurses, each of whom was doing twelve hours’ duty. Strychnin has been routinely given with the thought of possible as- sociated involvement of the cardiac ganglion. Moreover, certain portions of the heart muscle obviously remain free from the degenerative process and may be favorably influenced by the strychnin. To a child one year of age 1/200 grain may be given three times daily. From the first to the third year 1/200 to 1/100 grain may be given four times daily. After the third year the dose is subject to considerable variation, the amount depending upon the urgency of the case. Ordinarily, from 1/100 to 1/75 grain may be given four times a day. If the case is very urgent and the strychnin appears to improve the heart action, it may be given to the point of producing its physiologic effects, such as fibrillary twitching of the muscles of the face and the backs of the hands. Nitroglycerin should not be used. Digitalis should be given with care to young children, as it is very apt to disturb the digestion if long continued; temporarily, in treating older children, it may be used with advantage. A child from five to ten years old may be given thrice daily (preferably after meals) from 3 to 4 drops of the tincture well diluted with water. The tinc- ture of strophanthus may be of more service than the digitalis. Dig- italis or strophanthus will be found particularly useful in those cases in which there is a tendency to rapidity of the heart action. A child one year of age may be given 1 drop of tincture of strophanthus every two hours in the twenty-four; from the first to the third year from 1 to 2 drops at two-hour intervals; and from the third to the tenth year from 2 to 4 drops at intervals of from two to three hours. Convalescence.—The tendency of myocarditis in children is toward recovery. How long each patient will require strict observation, and how long the treatment will ultimately need to be continued, must be determined by each individual case. One fact to be remembered, ac- cording to our experience, is that the child either dies suddenly or makes a complete recovery, so that in treatment it is well to err on the side of caution. It has been found safe, in a very few instances, to allow the child to sit up after six weeks. In the very severe case above referred to it was not safe for the patient to sit up in bed until the end of the third month, and he was not allowed to walk until the end of the fourth month. After being kept under observation for one year he was discharged, and has remained well during the ensuing years. At the present time there is no evi- dence whatever of his former illness. A safe rule to follow is to keep the patient in bed as long as the rapid- ity or irregularity of the heart exists. When the heart action in the re- cumbent position is apparently normal, the patient may be allowed to have his head raised by an additional pillow. In this way the head anti shoulders may be gradually raised higher day by day, so long as the CHRONIC VALVULAR DISEASE OF THE HEART 425 effect upon the heart muscle is not unfavorable. In the same way standing and walking may be gradually resumed. Following out this careful method of heart rest, and being governed solely by the heart action, which indicates the heart power, one will see apparently hopeless cases completely recover. Whether fibrous changes in the myocardium are present which may have a later influence there is, of course, no means of knowing. CHRONIC VALVULAR DISEASE OF THE HEART Chronic valvular disease of the heart (acquired) is the end-result of an endocarditis which has resulted in certain changes in the valves and cardiac orifices, producing a permanent lesion. The acquired lesion in children will practically always be found on the left side of the heart, involving the mitral or aortic valve. With such lesions, compensatory hypertrophy, a conservative process, is usually associated. Etiology.—A most important feature to keep in mind in connection with valvular disease of the heart in children is the source of the disease. A large proportion of the cases (95 per cent, in our own experience) are due to rheumatic endocarditis. In the absence, then, of a history of endocarditis in association with pneumonia, diphtheria, or scarlet fever, which association in our experience has been rare, it may be assumed that the valvular lesion is of rheumatic origin, even though there may not be elsewhere, at the time, positive evidence of rheumatism. Not a few children showing cardiac disease without a history of actual acute rheu- matism have a history of tonsillitis, angina, coryza, asthmatic bronchitis, or chorea, all showing recurrent tendencies. Such patients will often be found to have a rheumatic or gouty ancestry, and not infrequently they themselves are hearty eaters of red meat and sugars. The great majority of cases of valvular defects recognized in early adult life are the result of unrecognized endocarditis of childhood. Janeway1 found that proved bacterial endocarditis is one of the rare causes of chronic valvular disease. Symptomatology.—Chronic valvular disease in children may exist unchanged for years if the lesion is not severe and if compensation is maintained. The first symptoms of failure of compensation are shortness of breath and rapidity of heart action, both of which the child may mention in describing the condition. If the heart is not relieved, the patient will soon present evidence of right heart failure, such as persistent general bronchitis, inability to assume the recumbent position, dropsy, and en- largement of the liver and spleen. Later the breathing becomes more difficult, the expression anxious, and the face drawn and cyanosed upon the slightest exertion. The superficial veins become dilated, and the pulse finally becomes very irregular and soft. Death in children with this disease is usually due to terminal bronchopneumonia. Diagnosis.—Valvular lesions are indicated by adventitious heart sounds, known as murmurs (p. 404), which are heard either with, or in place of, the normal sounds (p. 401). The character, time, point of maximum intensity, and area of trans- 1 Boston Med. and Surg. Jour., vol. clxxiv, No. xxvi. 426 THE PRACTICE OF PEDIATRICS mission indicate the location, and to a fairly accurate degree the nature, of the lesion. Prognosis.—The prognosis depends to a large degree upon both the location and the nature of the lesion. In mitral regurgitation with good compensation the possibilities for long life are favorable, depending some- what, of course, upon the age and condition of the patient. If the case is of long standing, the possibility of a complete cure is not to be considered. An unknown factor in these cases which has important bearing upon the future is the possibility of reinfection. When rheumatic endocarditis has once existed in a child, it is likely to return; and in the event of recovery from a second or third attack, the heart is left in a more serious condition than ever before. Mitral regurgitation with good compensation may not seriously in- convenience the individual for years if careful habits of life are followed. Neither need a mild degree of uncomplicated aortic stenosis cause great anxietj'-. Nevertheless, we always look upon stenosis at either the mitral or aortic orifice with apprehension, and our own results with the stenosis cases during years of observation have been far from satisfactory. Aortic regurgitation is often associated with aortic stenosis, and the outlook for such patients as well as those with mitral stenosis is not favorable as regards the duties of active adult life. If there is one word more than another that typifies the life of a child, it is the word “stress.” Activity and excitement are so inherently a part of child life that the heart crippled by aortic disease is often called upon to do work which is impossible. Even if the patient attains the fifteenth year without loss of compensation, the heart is in a condition that entails semi-invalidism. Treatment.—Realizing that rheumatic endocarditis is very likely to return, we should make it our first duty, after acquainting ourselves with the probable origin of a given case of valvular disease, to explain to the parents that other attacks are very likely to occur unless means are used for prevention. Enucleation of the tonsils and removal of bad teeth should be practised here as after acute endocarditis. In the absence of a history of endocarditis in association with pneu- monia, diphtheria, scarlet fever, or other infections, it may be assumed that the lesion is of rheumatic origin, even though a history or actual evidences of rheumatism may be lacking. Our next step in the management must be to regulate the life so as to prevent a recurrence of the heart involvement. With this end in view, it should be directed that red meat be given the child but once every second day, and that cane-sugar be given in great moderation. A diet of plain, nutritious food, with nothing between meals, is a very important feature in the treatment of heart disease in children. Poultry, fish, eggs, milk, and cereals with high protein content may be given in increased amount in order to maintain nutrition. A tub-bath followed by a dry rub should be given daily. The bowels must not be allowed to become constipated, and moderate exercise should be encour- aged. The importance of woolen underclothing if only of light weight should be emphasized in dealing with the rheumatic child, and protection from CHRONIC VALVULAR DISEASE OF THE HEART 427 sudden temperature changes should be insisted upon even if a complete change of climate seems necessary to secure such protection. Drugs Advised.—For five successive days out of each month a patient from five to ten years old should be given, after meals, 5 grains of sal- icylate of soda and 10 grains of bicarbonate of soda. This, with the low meat and low sugar diet, is usually, but not invariably, sufficient to pre- vent a recurrence. Occasionally it becomes necessary to give the above treatment for five days with intervals of only ten days. An interesting outcome apparently to be attributed to treatment has repeatedly been an entire disappearance of the growing pains, recurrent bronchitis, or low- grade eczema, with which the child may have been afflicted. Drugs Used With Caution.—The further management of valvular disease depends to a certain extent upon the location and nature of the lesion. Because a child has a cardiac lesion he does not necessarily require digitalis. Not a little harm is done, in the treatment of diseases in chil- dren, by giving powerful drugs when they are not indicated. Too often in heart disease the physician feels his duty done when he gives digitalis. Many times children will be found taking digitalis and strychnin because of some cardiac lesion, while, at the same time, they are suffering from constipation, recurrent respiratory disorders, and persistent indigestion due to dietetic errors, all of which have escaped the attention of the physician. Mitral Regurgitation.—In mitral regurgitation, well compensated, the activities need be but little curtailed; in fact, the patient may be en- couraged to indulge in outdoor exercise, although competition in all games requiring unusual exertion, tests of speed or endurance of any nature, such as running and racing, should be forbidden. When the child is old enough, swimming, bicycling, horseback-riding, and golf may be advised. Boys, on arriving at the tobacco and alcohol age, must be told the dangers attending the use of either drug, and both must be forbidden. Girls with mitral insufficiency must be warned against excessive dancing, rope jumping, tight lacing, and indiscriminate eating. For patients of both sexes rational exercise is beneficial. Mitral Stenosis and Aortic Disease.—When the aortic valves are involved either in insufficiency or stenosis, or when there is a consider- able degree of mitral stenosis, the child’s activities should be considerably limited. Under these conditions, with a view to the future, regardless of satisfactory existing compensation, it is essential to forbid the bicycle, swimming, dancing, baseball, or any sport or game which may call for much physical effort. Plenty of entertainment may be provided which does not call for great effort. The nature of the disease should be fully explained not only to the parents but also to the patient when the latter is old enough to understand, so as to secure hearty co-operation in govern- ing the child’s activities. Moreover, parents should be told particulaily that tonsillitis or angina is a danger-signal, and that, on the occurrence of either condition, the salicylates are to be brought into use at once, even before the physician is summoned. Ordinarily, it is not well to talk over a child’s ailments with him or in his presence. To older children with cardiac disease, however, it is advisable to explain as clearly as possible the nature of the illness, and 428 THE PRACTICE OF PEDIATRICS insist that certain measures, particularly such as relate to restriction of activity, shall be carried out indefinitely. In this way better co-operation on the part of the patients is secured than if they are simply given a list of dogmatic “dont’s.” It is, furthermore, most important, in cases showing aortic involvement or mitral stenosis, to advise what is known as “heart rest.” Every day after the midday meal, with clothing off or loosened, the child should be made to rest in a recumbent position for at least one hour. During this time he may sleep or read as suits his individual taste. Constructive Medication.—As most of the cases of valvular disease in children are of rheumatic origin, it will be found that the majority of the patients are suffering from a mild degree of anemia. All the benefits of good nutrition, fresh air, and regularity in living referred to under Tardy Malnutrition (p. 146) should be secured to these children. Iron alone or with arsenic is here of some value when given with a suitable diet. A method often followed is to give, for five days, the salicylate and bicar- bonate of soda already referred to; for fifteen days iron and arsenic; and during the remaining ten days of each month no medication, unless cod- liver oil is well borne, in which case this may well be given in combination with the extract of malt. If the patient can swallow a capsule, the follow- ing is recommended: 1$. Liquoris potassii arsenitis gtt. xc Extracti ferri pomati gr. x Quininae bisulphatis 3 j M. ft. capsulae no. xxx. Sig.—One after each meal. If the iron produces constipation, to \ grain of the extract of cascara may be added to each capsule. Heart Stimulants.—Aside from such tonic medication, drugs affecting the heart itself should not be given unless compensation fails. This may take place temporarily, regardless of the nature of the lesion, after some forbidden exercise, or during an acute illness sufficient to produce pros- tration. Such failure may occur permanently in cases which, for any reason, do badly. In the event of defective compensation and dilatation, the child should be kept in bed until the normal heart action is restored by rest, or until it is demonstrated that the aid of heart stimulants is required. In these cases (particularly in those of the latter type, when there is a rapid, irregular pulse, difficult breathing or excitement, and dropsy) the time-honored remedy, digitalis, is to be brought into use. For children we prefer ordinarily to use the tincture. To a child from five to ten years old from 3 to 5 drops may be given after meals three or four times daily. This drug, because of its well-known irritant effects upon the stomach, should be given considerably diluted. In the administration of digitalis, when it is desired to obtain the therapeutic effect as rapidly as possible, the dosage may be regulated ac- cording to the Eggleston method.1 This method employs as the average therapeutic dose of a first-class tincture 0.145 c.c. for each pound of the patient’s weight. ‘‘In this way it is possible to give a third to half of the total calculated therapeutic dose at a single administration, to follow this in from four to six hours with a 1 Cary Eggleston, Archives Int. Medicine, vol. xvi, pp. 1-32. ADHERENT PERICARDIUM 429 quarter to a third of the total dose, and to give the remainder in a few doses of smaller size at intervals of from four to six hours. By this plan of administration the full effects can be secured in from twelve to thirty- six hours in the majority of cases.” Beneficial effects will be apparent first in the relief of the dyspnea, the pulse becoming regular and of increasing volume; and later in the in- creased excretion of the kidneys and the disappearance of the edema. The amount of digitalis given should be reduced as soon as the condition will allow, but the medicine may be continued for a considerable time after the patient is up and about. The only contraindications to the use of digitalis in children are its effect upon the stomach and the occurrence of heart-block (p. 408). When loss of appetite results, the preparation should be discontinued. In this event the tincture of strophanthus, which is referred to repeatedly in this work as a heart stimulant, may be sub- stituted in the same doses. In cases requiring a cardiac stimulant for a considerable time or permanently, satisfactory results have followed the practice of alternating the digitalis with the strophanthus, giving each for five days. The child, however, who requires constant cardiac stimulation promises but little for the future, and, in our experience, few patients of this type have survived the eighteenth year. ADHERENT PERICARDIUM As a result of an unresolved pericarditis with which a myocarditis may or may not have been associated, adhesions often exist which bind the pericardium to the heart muscle, in most instances completely obliter- ating the pericardial sac. The condition is found in cases in which there is extensive cardiac disease, with hypertrophy, dilatation, and valvular involvement. Diagnosis, if made at all, is usully made at the autopsy. The diag- nostic sign of real differential value is a retraction of the chest wall in the interspace corresponding to the apex-beat. Sometimes permanent cardiac friction-sounds may be heard, and there usually is an increase in the cardiac dulness to the right of the sternum. XIII. THE BLOOD AND BLOOD DISEASES THE BLOOD IN THE NEWBORN According to Schiff, Perlin, Carstanjen, Scipiades, and Takasu the blood of a newborn baby exhibits numerous characteristic changes. 1. The specific gravity averages between 1.060 and 1.080, but during the first two weeks rapidly sinks to its lowest point, at which it usually re- mains until the end of the second year of life, after which it rises until puberty, the average thus being between 1.050 and 1.055. 2. The percentage of hemoglobin is very high—usually between 100 and 140 per cent, of that found in the healthy adult. 3. The red cells, which are greatly increased, may number as high as 7,550,000, and usually above 5,000,000. 4. The white cells are also increased, in one case numbering 36,000. 5. According to Carstanjen, the polymorphonuclears number 73.4 per cent.., as compared with 16.05 per cent, lymphocytes. 6. A large number of nucleated red cells are present up to the sixth day, after which scarcely any are to be found. The variations noted become less marked after the fourth day. The number of polynuclear leukocytes diminishes, and after the fourth day the percentage of the various kinds of leukocytes is fairly constant during the first few months. It is suggested that many blood changes observed in the newborn are due to the lack of water, a considerable amount of which is lost through the intestine and in the form of perspiration. THE BLOOD IN INFANCY AND CHILDHOOD Hemoglobin.—Throughout the period of infancy and childhood the hemoglobin is lower than in the adult, its minimum being usually reached between the third month and the second year. From this point it grad- ually increases until puberty. The average hemoglobin of childhood is between 65 and 85 per cent., the former being considered a low limit for a healthy child. Red Cells.—The average number in infancy is from 4,000,000 to 5,500,000, and in later childhood from 4,000,000 to 4,500,000 (Hayem). In the blood of the fetus and in premature infants nucleated cells are seen, but in later infancy their presence must always be considered path- ologic. Formerly their occurrence even in healthy children was con- sidered the rule. Blood-platelets.—These are normally present to the number of about 350,000 per centimeter. They are now regarded as “pinched off” processes of giant-cells of bone-marrow varying from 2 to 5 microns in diameter. For their study the Wright and Kinnicutt. method of dilution with a cresyl blue and potassium cyanid mixture is considered standard. THE BLOOD IN INFANCY AND CHILDHOOD 431 The blood-platelets are diminished in aplastic conditions of bone- marrow, as in pernicious or aplastic types of anemia, in severe infectious diseases, and in purpura hsemorrhagica. In leukemia, trichinosis, and following hemorrhage the platelets are abundant.1 Normal White Corpuscles.—In health the following varieties are found: 1. Lymphocytes.—These cells vary from 5 to 10 microns in diameter. The nuclei are relatively large, round, deeply stained, centrally placed, and contain one or two nucleoli. The cells may be deeply notched, especially the smaller ones, and even suggest polymorphonuclear cells, but are never identical in appearance. The protoplasm forms a narrow rim around the nucleus and is sometimes reticulated. The nucleus stains with basic dyes more faintly than the protoplasm. The larger cells of this group have an irregularly staining nucleus with a chromatin network and a margin of faintly granular protoplasm. The lymphocytes constitute from 40 to 60 per cent, of the leukocytes in the normal infant’s blood. 2. Large Mononuclears.—These are not polymorphous cells, but contain a single round or large oval nucleus, and are usually two or three times as large as red blood-cells. The protoplasm is homogeneous and relatively large in amount. These cells constitute about 4 to 6 per cent, of the leukocytes. 3. Transitional Cells.—These are usually larger than the large mono- nuclears, which they closely resemble; in fact, they are the largest cells of the blood. They possess a “wallet” or “saddle-bag” nucleus. During the first few months they comprise 8 to 10 per cent, of the white cells (Carstanjen, Karnizki). 4. Polymorphonuclear Neutrophils. — These cells, which constitute from 18 to 40 per cent. (Emerson) of the child’s blood, are somewhat smaller than the transitional cells. The nucleus is characterized by its polymorphous nature and its deep stain, while the protoplasm is well filled with neutrophil granules, which may cover the nucleus. 5. Eosinophils.—These are usually of the same size as the preceding, and occasionally a little larger. The nuclei are fairly well stained, while the protoplasm is filled with large eosinophilic granules. These cells constitute 2 to 4 per cent, of the normal white cells. 6. Mast Cells.—These are about the same size as the preceding, but frequently smaller; they have a trilobed nucleus and a protoplasm con- taining many large basophilic granules; often they are metachromatic. Their proportion is about 0.5 per cent, of the white cells. Leukocytes Found in Pathologic Conditions: 1. Myelocytes.—While any cell of bone-marrow is, strictly speaking, a myelocyte, by this term is generally meant one with a round nucleus and a granular protoplasm. Neutrophilic and eosinophilic myelocytes occur. Their size varies from that of the large mononuclears to that of red corpuscles. The nucleus is round, oval, and sometimes kidney shaped, but never polymorphous; it is usually centrally placed, and is not stained diffusely by any good nuclear dye. The protoplasm may contain many or few granules of the neutrophilic type. 2. Eosinophilic Myelocytes.—These resemble the polynuclear eosino- phils, except for the rounded, undivided nucleus. 1 Stitt, Practical Bacteriology. Blood Work, Parasitology, 7th ed., pp. 328, 329. 432 THE PRACTICE OF PEDIATRICS In pathologic conditiohs the leukocytes undergo various degrees of degeneration, both acute and chronic. There may be swelling, frag- mentation, and hydropic and fatty degeneration, with nuclear changes. According to Rieder, the leukocytes average from 8700 to 12,400 between the second and fourth days; after the fourth day, from 12,400 to 14,800. In infancy the variations are from 9000 to 14,000; in later childhood, from 6000 to 12,000. When the second year is reached, the blood gradually begins to assume the adult type. This, however, is not attained until the fifteenth or sometimes the twentieth year. Up to the sixth year there is a preponderance of lymphocytes. Sex makes no material difference until the fifteenth year. The blood-making organs of the infant are severely affected by disease. The infantile blood readily takes up myelocytes and nucleated cells (Zelenski-Cybulski). Leukocytosis.—By this is meant an increase in the number of white corpuscles in the blood. It may be of two varieties—relative and abso- lute. A relative leukocytosis is more frequent in children than in adults. By the leukocytosis one may judge the nature of the reaction of the organism to bacteria or to the toxins in the blood elaborated by the bac- teria concerned in the inflammation or infection. It may thus be seen that the reaction of the individual will depend upon two factors: (a) the severity of the infection and (6) the resistance of the individual. Of the two, the latter is more important. It is a fact that the most marked degree of leukocytosis is observed in a healthy, well-nourished child suffering from a severe infection; while, on the other hand, a feeble child suffering from the same infection will have a slight leukocytosis or prob- ably none at all. The nature of the reaction depends upon the character of the inflammatory process. Leukocytosis is less marked in serous and more pronounced in suppurative processes, while in both instances it is highest during the stage of active exudation. In well-localized suppurative inflammations there may be no leukocytosis at all. Leukocytosis is present in a great many pathologic conditions, and in some cases the explanation is wanting. A satisfactory division of leukocytosis is into the two groups: (a) physiologic and (h) pathologic. By the former is meant that which follows a meal or exercise or that which occurs in the newborn; by the latter is meant that which may occur after serious hemorrhage, malignant disease, and various inflam- matory and toxic conditions. Japha has not been able to demonstrate a genuine leukocytosis of digestion in the bottle-fed infant, and Greger did not even find it regularly present in the breast-fed infant. If, how- ever, a breast-fed infant was given cow’s milk, there was an immediate occurrence of leukocytosis, and hence the opinion (Moro) that it is a re- action against foreign protein. Children show a more pronounced di- gestive leukocytosis than adults, occasionally the increase amounting to one-third of the total number of leukocytes. The chief form of leukocytosis in children is the inflammatory type. This is especially noticeable in acute pneumonia, diphtheria, acute rheu- matism, erysipelas, scarlet fever, tuberculous meningitis, and in sup- purative conditions of the subcutaneous tissues, serous cavities, bones, joints, and viscera. In these conditions the increase is chiefly in the polymorphonuclear neutrophils. THE BLOOD IN DIFFERENT DISEASES 433 In pertussis, hereditary syphilis, and certain diseases of the spleen there is a relative increase in the lymphocytes, while in leukemia, asthma, helminthiasis, and some forms of chronic skin disease there is an increase in the eosinophils. There is usually no leukocytosis in typhoid fever, measles, rotheln, mumps, malaria, and uncomplicated tuberculosis not invading the me- ninges or serous surfaces. In the usual forms of gastio-enteritis leukocyto- sis is absent, while in “Finkelstein’s alimentary food intoxication” it is pronounced. THE BLOOD IN DIFFERENT DISEASES Pneumonia.—In this disease there is regularly a leukocytosis, and it is in this illness that the inflammatory leukocytosis has best been studied. The leukocytosis here is an expression of the resistance of the organism to the infection, and depends but little on the fever and the extent of consolidation (Ewing). In an average case the count may vary between 15,000 and 40,000 or 50,000, and but rarely reaches 100,000; although there are a number of cases on record with a count as high as this. A high count gives no idea of prognosis; it means that the pro- tective forces are making a vigorous fight, but gives no hint as to which will win, they or the infection. Absence of leukocytosis is usually of bad import, and shows that the patient has low resistance; and a rapid fall with either a low or a high temperature is usually indicative of a loss of resistance on the part of the patient. The fall in the count begins just before, just after, or with, that of the temperature; this diminution usually corresponds to the change in temperature. If the count remains elevated, delayed resolution, empyema, or abscess should be suspected. The increase is mainly in the polymorphonuclear cells, which may vary from 60 to 90 per cent, of the total leukocytes. In pneumonia following pertussis the increase is chiefly in the lymphocytes. The absence of a leukocytosis in a strong, well-nourished child who is very ill is always strong presumptive evidence against pneumonia. The changes in the red cells and hemoglobin are those of a secondary anemia, depending on the duration of the disease and the resistance of the patient. Leukocytosis is present in both forms of pneumonia in infancy and childhood, but is more marked in the lobar form, the number of leu- kocytes to the cubic millimeter being about twice as many as in the catarrhal types. There is marked leukocytosis in the fatal cases of both forms of pneumonia (Koplik). Empyema.—Marked leukocytosis is almost invariably present with a high polymorphonuclear count-—usually from 75 to 90 per cent. In cases of long standing there is often no leukocytosis, but the polymor- phonuclear count remains elevated. In tuberculous effusions the count is usually low, with no increase in the polymorphonuclear count. Influenza.—Uncomplicated influenza has no leukocytosis and fre- quently induces a leukopenia. Influenzal pneumonia ordinarily has a leukocytosis of from 15,000 to 20,000. To date no uniform conclusions have been arrived at concerning any characteristic differential count other than that of an ordinary pneumonia. Tuberculosis.—In tuberculosis, in general, there exists a mild grade 434 THE PRACTICE OF PEDIATRICS of chlorotic anemia with little or no leukocytosis. The count is nearly normal, while the hemoglobin is somewhat reduced. In other cases there is a lymphocytosis, absolute or relative. If a secondary infection occurs, which is not infrequent in infants and young children, leukocy- tosis is the rule, and, in fact, Limbeck considers the presence of a leu- kocytosis sufficient guarantee of a secondary infection. In case of pneu- monia the leukocytosis is as high as in the ordinary croupous pneumonia. Various observers are of the opinion that in incipient tuberculosis there is a slight increase in the eosinophils, and that, as the infection progresses, they diminish. From a series of 182 blood examinations of tuberculous patients Solis-Cohen concluded that an increase in the polynuclear count points toward an advance of the disease and vice versa. In tuberculous bronchial adenopathy and peritonitis, leukocytosis is absent, although in the latter Cabot reported an increase in the cell count in 14 out of 60 cases. Tuberculous meningitis regularly causes a leukocytosis, reaching at times as high as 50,000, while there is usually a polymorphonucleosis, in some instances as high as 90 per cent, of the total white cells. In bone and joint disease the leukocytes are normal or very slightly increased, and only during abscess formation or following operation is there an ap- preciable increase in the cell count. Typhoid.—As in adults, there is a low white cell count, generally under 10,000. The lymphocytes are slightly increased, and there is usually a mild grade of anemia. Rheumatism.—There is regularly a leukocytosis and a severe grade of secondary anemia. Peritonitis and Appendicitis.—In the former there is a polymorpho- nuclear leukocytosis. This, however, is wanting in some cases of the severest type. In a series of 70 cases of appendicitis in children reported by Fowler in 1912, the average leukocyte count was 19,106, the average polynuclear, 79.7 per cent.; the highest leukocyte count was 48,200; the lowest, 8200; the highest polynuclear count, 92 per cent.; the lowest, 63 per cent. Meningitis.—In cerebrospinal meningitis and in meningitis caused by the other pyogenic organisms there is regularly a leukocytosis with an increase in the polymorphonuclears. The leukocyte count is of no value in distinguishing the various forms of meningitis, since it is also present in the tuberculous form (Emerson). Poliomyelitis.—Until a monograph on poliomyelitis by Draper, Peabody, and Dochez, of the Rockefeller Institute, was issued, a num- ber of conflicting statements had been made concerning the blood findings in this disease. Previous to this clinical study by the above authors, Muller, in Germany, and La Fetra, in New York, had made the most extensive observations. The latter reported a leukocytosis between 13,400 and 20,600, while Muller found a leukopenia in the acute stage. Draper, Peabody, and Dochez tabulated their findings in 59 hospital cases, and came to the conclusion that in the preparalytic stage the counts varied within the normal, but that there was a tendency toward a leu- kocytosis. In the acute stage, in every case except one in which leu- kopenia existed, there was a marked leukocytosis, in several instances reaching as high as 30,000. In addition to this increase in the white cell THE BLOOD IN DIFFERENT DISEASES 435 count they found a constant increase in the polymorphonuclears of 10 to 15 per cent, and a diminution of lymphocytes of 15 to 20 per cent. The other white cells showed no abnormalities. In view of these findings a definite leukocytosis with an increase in the polymorphonuclears and a corresponding diminution of the lymphocytes is additional evidence, when considered with other available signs, in favor of the disease in question. Diseases with Eosinophilia.—Asthma.—In true bronchial asthma the eosinophils may be from 10 to 20 per cent. Cases have been reported with eosinophilia as high as 50 per cent. Holt gave 10.7 per cent, as the average in a series of cases examined in his clinics by Wile; the highest was 26 per cent. The presence of an eosinophilia serves to distinguish the attack from one of acute bronchitis or tuberculosis. The occurrence of an increase in the eosinophils apparently determines the asthmatic character in certain spasmodic attacks of the respiratory system in in- fancy. Eczema.—There is no difference between the number of eosinophils in infancy and childhood and that in adult life. Occasionally an eosino- philia is noted in pemphigus. Parasites.—Any parasite, from the harmless pinworm to the most malignant uncinaria, may cause eosinophilia. It is not always present, nor does its degree bear any relation to the severity of the infection or the danger of the parasite. The presence of eosinophilia in a child should always make one suspicious of intestinal worms. Amberg, in studying amebic dysentery of children, found a slight increase in the eosinophil count. The average number of these cells in parasitic diseases is from 4 to 10 per cent, of the total white cell count, but these figures may be exceeded. In not a few cases symptoms of pernicious anemia have been present, and a severe grade of secondary anemia may exist. In one of our cases of trichinosis the eosinophil count was 72 per cent. Syphilis (Congenital).—There is usually a relative increase in the mononuclear cells and a severe secondary anemia, while a case with a severe rash, especially involving the face, may develop an eosinophilia as high as 23 per cent., diminishing as the condition improves. Gastro-enteritis.—In this disease there is usually no leukocytosis, although in some cases a slight increase may be noted. It is remark- able that even in long-standing cases of gastro-enteritis and enterocolitis there is not a great reduction in hemoglobin. In Finkelstein’s food intoxication one of the cardinal signs is a leu- kocytosis of from 20,000 to 40,000, the largest cell percentage being of the polymorphonuclear variety. Acute Contagious Diseases.—Whooping-cough.—In this disease the leukocytes are increased to three or four times the normal amount, averag- ing 40,000 (Emerson). The change is more pronounced the younger the child. The early appearance of a leukocytosis is important in diag- nosis. The increase is chiefly in the lymphocytes, which may constitute from 60 to 80 per cent, of the total white count. A moderate eosinophilia may be noted. According to Frohlich and Muenier, the leukocytosis of pertussis far exceeds that of any other afebrile disease of the respiratory tract. 436 THE PRACTICE OF PEDIATRICS The leukocytosis occurs in the early part of the convulsive stage, dis- appears with improvement, and does not seem to be influenced by com- plications. Measles.—Hecker recorded the results of his blood examination of 14 children. In the incubation period his observations were uniform, and he concluded that during the incubation period, and occasionally extending into the eruptive period, there existed—(1) a leukopenia; (2) a relative lymphocytosis; (3) reduction in the number of eosinophils. In 13 cases in the prodromal period Platinger found a neutrophil hyper- leukocytosis of even 20,000, which rapidly gave place to a hypoleukocytosis during the eruptive stage. According to Holt there is a leukocytosis of 15,000 to 30,000, beginning soon after infection and increasing for four or five days. A marked increase in the leukocytes during the illness usually points to a complication. Hektoen, in his animal experimentation and observation on human beings, found that there was a preliminary leu- kocytosis, followed by a leukopenia, chiefly of the polymorphonuclear neutrophils, the lymphocytes being relatively increased. Diphtheria.—In this disease there is a moderate anemia, a loss of about 2,(X)0,000 red cells at the time of defervescence (Emerson, Ewing). The reduction in the hemoglobin is usually proportionate to the reduc- tion in the red cells. There is usually a slight leukocytosis, ranging, as a rule, from 10,000 to 15,000, but in severe cases the white cells may number 17,000 and, with complications, 30,000 (Emerson). The rise is in the polymorphonuclear cells. According to Engel, the myelocytes are increased, especially in the fatal cases, from 3 to 16 per cent. Morse has said, “The examination of the blood in diphtheria is of no practical clinical importance in diagnosis, prognosis, or treatment.” Scarlet fever produces little change in the red blood-cells, but does cause a slight anemia (Reckzan), the average drop being 1,000,000. There is uniformly a leukocytosis, beginning in the incubation period and continuing into convalescence (Emerson). The leukocytes vary from 10,000 to 40,000; in mild cases from 10,000 to 20,000; in moderate cases from 20,000 to 30,000; in severe cases from 30,000 to 40,000, while, ac- cording to Holt, the number may be as high as 75,000. The variation is according to the severity of the case. The increase is chiefly in the poly- morphonuclear cells, which may constitute 85 to 98 per cent, of the total count, especially in severe and fatal cases. At first there is a complete disappearance of the eosinophil cells, and later a rapid increase (20 per cent.). The disappearance of the eosinophil cells during the course of the disease is a bad prognostic sign, and absence of leukocytosis is also ominous. In the Centralblatt fur Bakteriologie of November, 1911, Dohle reported, in 30 cases of scarlet fever, certain inclusion bodies found chiefly in the leukocytes. More recent work by Nicoll, of New York, and Kolmer, of Philadelphia, showed that these bodies were present in streptococcus infections, and the latter observer reported their presence in 42 per cent, of diphtheria cases. The inclusion bodies are present in 94 per cent. (Kolmer) of scarlet fever cases during the first three days; after this they diminish in number, and are generally absent after the ninth day. Thus, while their diagnostic value is necessarily limited, their presence has BLOOD-PRESSURE IN CHILDREN 437 been considered useful in the differential diagnosis of scarlet fever, rotheln, measles, and gastro-intestinal rashes. Congenital Heart Disease.—Of congenital affections, this disease presents the largest number of cases of polycythemia, although, as Osier stated, “polycythemia is not a constant feature in congenital cyanosis. It is characteristic rather of the latter stages of the disease, and its ap- pearance is said to be of unfavorable prognosis.” Vaquez and Quiserne stated their belief that when the polycythemia reaches 6,000,000 it seems to be fatally progressive, evidencing a more and more insufficient aera- tion, the prognosis becoming correspondingly graver. The red cells frequently reach 6,000,000 to 7,000,000, and the percentage of hemo- globin may be as high as 160, and the specific gravity 1070; naturally the blood-clot is greatly increased, owing to the excess of red blood-cells. Cautley reported a case of polycythemia of 10,000,000, and Still, one of 9,280,000. The white blood-cells are not increased. BLOOD-PRESSURE IN CHILDREN During the past few years numerous observations of the blood-press- ure in different diseases have been made by Rolleston, Sergeant, and Hutinel, abroad, and by Howland and Hoobler in America. A simple and easily handled machine of the Riva Rocci type is the Faught, with a cuff made from an ordinary Voorhees uterine dilating bag. With this combination the smallest arm can be readily accommodated. An exact estimation of the pressure is not always possible on account of the small size of the radial artery and the overlying thick pad of fat, which makes palpation rather difficult, and especially so when an infant struggles, as is not infrequently the case. According to Kolossowa, Oppenheimer, and Bauchwitz, the follow- ing figures may be considered normal for systolic pressure: Age, Mm. of years. mercury. 1-2 75-85 3-4 85 5- 7 90- 95 8-10 95-100 11-13 100-110 The diastolic pressure during infancy is about 45 to 50 mm. of mer- cury and rises slowly and gradually until puberty, when it maintains a fairly constant level at about 60 mm. The pulse pressure in infancy is 18 to 20 mm. of mercury, gradually increasing to about 30 mm. at three years of age. After ten years the pulse pressure is that of the normal adult, viz., about 40 mm. of mercury.1 Faber and James2 have shown that there is no significant difference between the mean systolic pressures of the two sexes between the ages of three and seventeen years. However, the mean diastolic and pulse pressures show much greater standard deviations or normal variability in adolescent girls. All febrile diseases tend to lower the blood-pressure. Comby, Hutinel, 1 Wiggers, Carl J., Circulation in Health and Disease, 1923, 2d ed., pp. 361, 362. 2 Amer. Jour. Dis. Child., vol. 22, p. 7, 1921. 438 THE PRACTICE OF PEDIATRICS and Rolleston have found a constant hypotension in scarlet fever and diphtheria, more pronounced in the former. These authors considered a severe degree of hypotension to be of bad omen, especially in scarlet fever, and they believed that this condition should be met by the ex- hibition of adrenalin hypodermically. Among other causes of hypotension Janeway enumerated hemorrhage, collapse, and the action of poisonous drugs, especially chloroform. Hypo- tension is also met with in the diarrheas and in bronchial asthma. The value of blood-pressure estimation in epidemic meningitis during intraspinal injections of serum will be referred to later. Increased blood-pressure is observed in conditions of acute cerebral compression and anemia and in acute nephritis complicated by uremia. COAGULATION TIME The great diversity of opinion on the normal coagulation time and that in various diseases has no doubt been due to the variety of instru- ments employed. Dependable results obtained are those of Rudolf (8.1 minutes) and Carpenter (9.5 minutes) working with different instruments. It has been definitely shown that ordinary surface puncture gives variable results, depending on the depth of puncture, temperature, air- currents, dust, etc.1,2 Owing to these wide variations, despite careful technic and regula- tion of apparatus, no constant results have been obtained. From a rather exhaustive study Carpenter and Gittings concluded that it is improbable that any important variation exists in the coagulation of the blood in diseases other than of the so-called hemorrhagic type. Rodda3 has shown that there is normally an increase in the coagulation time of newborn infants (about seven minutes), which reaches its max- imum on the fourth or fifth day. This is the period of greatest incidence of hemorrhagic disease of the newborn. From the fifth day on there is a gradual decrease in coagulation time, till by the tenth day it lies within ordinary normal limits. In general, the bleeding time, three and a half to four minutes, follows the curve of the coagulation time. As a general rule, average differences of one, two, or three minutes can hardly be construed as of any practical importance, inasmuch as a differ- ence of from five to twelve minutes has been found in typhoid fever by authoritative observers. SIMPLE ANEMIA Simple anemia is usually a secondary condition, and is not at all in- frequent in children. A vast majority of the cases coming under our observation are those of children of the runabout age, and older chil- dren who are suffering from tardy malnutrition, having been badly fed and having wasted their energy in different ways. Simple anemia may be the result of hemorrhage, as in hemorrhagic disease in the newborn 1 Lee and White, Amer. Jour. Med. Sci., 145, 495. 2 Lee and Vincent, Arch. Int. Med., 13, 398, April, 1914. 3 Amer. Jour. Dis. Child., vol. 19, p. 269. SIMPLE ANEMIA 439 and in purpura, particularly purpura fulminans (Henoch’s). In the average case of anemia the hemoglobin ranges from 40 to 50 per cent., and the red cells from 3,500,000 to 4,000,000. Children suffering from tuberculosis and syphilis usually show a secondary anemia. It is also temporarily present after pneumonia, scarlet fever, diphtheria, and typhoid fever, and similar diseases which have severely taxed the or- ganism. A great many cases develop in runabout children under three years of age, for whom the milk diet has been continued as the almost exclusive means of nourishment. Children of the poor, because of the defective feeding and housing, are frequent sufferers. Symptoms.—The chief symptom is that of lack of endurance. The ap- petite is usually indifferent and the bowels are constipated. Such chil- dren tire readily, and are unable to keep up with their fellows at play or in school. They sleep poorly and, as a rule, are irritable and unhappy. In appearance they are apt to be pale and thin, although this is not invariably the case, as severe anemia is repeatedly observed in plump children. Illustrative Case.—A very pronounced case was that of a boy of six years who weighed 46f pounds. The blood examination showed: hemoglobin, 18 per cent.; red cells, 660,000. In two weeks the hemoglobin was 20 per cent.; the red cells, 640,000. Five weeks after first examination the hemoglobin was 30 per cent.; red cells, 1,172,000. The blood examination was checked up by a second person. No further improvement had taken place after one year of treatment. It seemed impossible without transfusion to raise the blood above 30 per cent, hemoglobin and 1,500,000 red cells. Anemic murmurs may be heard over the heart, but this has been unusual in our cases. In the case referred to the heart sounds were normal. The spleen is not often found enlarged. Examination of the blood in this condition of anemia enables one to estimate with accuracy the severity of the process. In mild cases there may be only a reduction in hemoglobin, and the blood may assume the chlorotic type. There is, in addition, a reduction in the specific gravity, depending on the degree of anemia, and if the primary affection, like pneumonia, causes an increase in the leukocytes, there will be a leukocytosis. In the cases of moderate severity the red cells may range between 3,500,000 and 4,000,000, and the hemoglobin from 40 to 60 per cent. In severe cases the red cells vary from 2,000,000, or a little less, to 3,000,000. There is a corresponding reduction in the hemoglobin. The more marked the reduction in red cells and hemoglobin, the more marked will be the poikilocytosis and polychromatophilia, and the greater the number of normoblasts and megaloblasts. In the severe cases myelo- cytes may be present. There is no increase in the eosinophil cells. In the severe secondary anemias the physical characteristics of the blood are very striking. It may be so thin as to separate on puncture into a reddish and a colorless portion resembling beef-water (Koplik). The prognosis is good in the cases in which syphilis and tuberculosis are absent. In fact, the majority of cases respond most satisfactorily to properly directed treatment. Treatment.—The management consists in placing the child in a normal child’s environment, which includes the giving of suitable food. 440 THE PRACTICE OF PEDIATRICS The treatment described under Tardy Malnutrition (p. 147) covers these cases. In pronounced cases transfusion offers the most prompt results. Management of Secondary Anemia Through Blood Transfusion by the Lindemann Method.—Signally satisfactory results have been obtained by this method of treatment. Infants with hemoglobin under 25 per cent. (Dare) and red cells under 2,500,000 have been permanently cured by one transfusion. So satisfactory have been the results that we now employ transfusion in all cases that fail to make a reasonably satisfactory response to other measures. The following table gives in a concise manner the results of trans- fusion in 8 cases: Blood Before Transfusion Blood After Transfusion THE PRACTICE OF PEDIATRICS 1 titioner invariably looks for pain as a symptom of the disease, and this has been the teaching of the books. In a search of many works on otology it was ascertained that the symptoms as laid down comprise almost ex- clusively the evidences of pain—earache—the pain being complained of by older children, or manifested in the very young by vigorous cry- ing, by tossing the head from side to side, by head-rolling, ear-tugging, crying out in sleep, disinclination to rest the head on the affected side, or pain upon manipulation of the ear. In short, we have been taught that there is invariably some manifestation of pain referable to the ear or the adjacent structures in all cases of acute otitis in infants and young children. Such symptoms exist in a moderate number of cases. The most interesting feature, however, in this series of 72 cases was the absence of pain or localized tenderness on manipulation in 50 of the cases, or 69 per cent. Among those included in the pain group, 22 in number, there were some cases which perhaps should not be so in- cluded, inasmuch as there were no signs of pain, as we generally expect to find it. The group included those who were very restless, who slept poorly, and who showed evidence of the relief which followed incision of the drum membrane, so that it was fair to assume that the source of the previous discomfort was the ear. Had we depended upon the signs of pain or local tenderness, in 50 of the cases a diagnosis of otitis at the time would have been impossible. Six were seen in consultation because of the unexplained continued fever. Nine had been treated by other physicians who had failed to discover the cause of the con- tinued fever. In none of these had ear involvement been suspected, because of the absence of pain and localized signs. Fever.—Among the 72 private cases already mentioned in well-nour- ished children one symptom was present in all—fever. There was noth- ing particularly characteristic in the temperature range. In some there were the morning drop and the evening rise. In others the temperature variations were inconstant. With but few exceptions the otitis developed during convalescence from an acute process localized elsewhere, the ear involvement being suspected because of a persistent elevation of the temperature for which no other cause could be discovered. The fact that 58 of the cases, or 81.5 per cent., occurred with or fol- lowed non-specific inflammatory conditions of the upper respiratory tract, such as tonsillitis, grip, and catarrhal colds, emphasizes the neces- sity for frequent aural examinations during or following such disorders, particularly when there is an elevation of the temperature, which, in the absence of definite clinical signs, we are apt possibly to attribute to chronic grip, malaria, typhoid fever, or dentition. Course.—In a small number of cases spontaneous perforation of the drum occurs. We have known the membrane to rupture in one hour from the onset of the ear symptoms, and have known it to remain intact with pus in the middle ear, to the best of our judgment, for ten weeks. In the average case, after a free opening of the drum, the discharge per- sists from ten to twenty days. In cases due to streptococcus infection the discharge is usually more prolonged. Prognosis.—The prognosis is good if the drum is freely incised and kept open. A certain small percentage of cases which is difficult to de- ACUTE OTITIS 661 termine develop mastoid disease, and a still smaller number become complicated by sinus thrombosis and jugular bulb involvement. Much depends upon the nature of the infection. If the streptococcus is found in the discharge mastoiditis as a complication is not improbable. The drum heals most readily. In numerous cases treated by free incision the drum has been found absolutely normal in appearance within three or four weeks after the discharge ceased. Diagnosis.—Fever without apparent cause should always call for an examination of the ears. Earache is a symptom demanding like attention. Otoscopic examination settles the diagnosis and is the means of con- firming or refuting symptoms of unsolved fever or indefinite pain. A culture should be made of the discharge from every ear opened. Complications.—The most frequently encountered complication is mastoiditis caused by extension of the infective process to the mastoid cells. The mastoid antrum is separated from the middle ear by a very delicate membrane. In many cases of acute otitis, probably in all cases showing prolonged discharge, the antrum is involved. If immediately after mopping out the canal there is a free discharge into the canal, this affords proof that the antrum is involved, as the small middle ear could not form pus with such rapidity. Prolapse of the posterior superior wall is another sign of mastoid involvement. The continuation of fever in spite of free aural discharge is indicative of mastoid abscess. If the mastoiditis exists, there may be swelling behind the ear or tenderness on firm pressure over the mastoid, particularly at the tip. Both of these symptoms—pain upon pressure and swelling—may fail us, and their absence is not to be considered in any way conclusive evi- dence against the presence of mastoid disease. There is no doubt that in many cases of prolonged aural discharge the antrum is diseased and supplies a large part of the pus, while the deeper cells in the bone escape infection. There are cases in which the mastoid is primarily involved; others in which there is a primary infection which takes in both the mastoid and the middle ear at the same time. To have mastoid disease does not mean that the middle ear must be primarily involved. Treatment.—A small percentage of the catarrhal cases in which there is congestion of the drum without bulging, will subside under irri- gation at two-hour intervals with normal salt solution at 110° F. One pint should be used. A fountain-syringe placed at an elevation of 3 feet above the child’s head affords the best means of irrigation. Regardless of the age or condition, a bulging drum in the presence of fever calls for incision. No harm is done to the ear by the free incision properly made, while much harm as the result of chronic otitis media and mastoid disease may occur when the incision is delayed. Operative.—Every practitioner who has children as his patients should be sufficiently familiar with the landmarks of the normal drum mem- brane at the various ages of early life to differentiate the normal from the abnormal. In the routine examination of the child, in all conditions associated with angina or fever, the ear should be included. In quite 662 THE PRACTICE OF PEDIATRICS young babies an otoscopic examination may show a dull, whitish appear- ing drum membrane which, on a superficial examination of the case, might be ignored. In all cases, particularly at this age, when the drum landmarks are indistinct, a cotton-pointed probe should be brushed over the surface, thus removing the epithelial scales which may have lodged there, with the result that perhaps a congested, bulging mem- brane may be revealed. Conditions or appearances of the drum membrane which require incision are often difficult of recognition by those not skilled in otoscopy. When the drum is bulging, deeply congested in appearance, with land- marks indistinct, an incision is necessary, and should be made in the posterior quadrant, beginning low down and extending upward through Shrapnell’s membrane. When also there is congestion of the drum mem- brane over the tubal entrance, and when the congestion extends toward the periphery, producing indistinct landmarks without bulging, incision is indicated. Postoperative.—The after-treatment following incision ordinarily consists in syringing the ear at three-hour intervals with 8 ounces of a saturated solution of boric acid for three or four days, after which the syringing may usually be practised at intervals of from four to five hours until the drum closes. In very young infants if the boric acid causes a deposit in the canal, it is well to change to a sterile normal salt solution, using the same quantity of fluid. In those cases in which only serum is present at the time of operation, closure within ten days may be expected; if, however, pus is present, from two to three weeks will be required. A sudden stopping of the dis- charge usually means that the opening in the drum is closed, either through plugging with thick pus or because of too early healing. In either event a re-establishment of the discharge by removing the obstruction or by reincision is essential. The chief factors in prolonging the discharge are adenoids and a lowered state of physical resistance. After the syringing the ear should be carefully dried with absorbent cotton. For purposes of syringing a l-ounce hard-rubber ear syringe with soft-rubber tip answers best. If this is not obtainable, a douche-bag, at an elevation of not more than 3 feet above the patient’s head, may be used. The douche-bag sometimes is desirable for those who are unskilled, or a soft-rubber bulb syringe of a capacity of 1 or 2 ounces may be used. The small double-current ear-irrigator may be used with advantage for the reason that it largely prevents wetting the patient. During treatment by any of these methods the child rests on his back with his hands pinned to his side by means of a large bath towel, while a pus basin is held under the ear to catch the flow. If the nurse can have an assistant, the upright position may be used. Delayed, Resolution.—In a certain number of cases resolution is de- layed and the discharge continues. In such cases a decided aid is fur- nished by the use of stimulating and disinfectant instillations. After the last syringing for the day the canal should be dried by the use of a wick of absorbent cotton. Five drops of the following solution are then to be instilled into the ear: P$. Pulv. acidi borici gr. xxv Spts. vini rect., Aquae aa 5ss A 15 per cent, solution of argyrol may be used in a similar manner. 663 MASTOIDITIS CHRONIC SUPPURATIVE OTITIS Not infrequently cases come under our care in which there is a purulent discharge from the ears, often most offensive, with a history that the discharge has followed measles, scarlet fever, or grip, and has continued for weeks or months. Examination may show a perforation of the upper portion of the drum, through which there is a free discharge, which, however, on account of the site of the perforation, is not sufficient to drain completely the middle-ear cavity. In other instances the examination may disclose an opening too small for effective drainage. Treatment.—In either case incision should be made and free drain- age established. The ear should then be syringed at least three times a day with a 1 : 10,000 bichlorid solution. The instillation of a solution of alcohol and boric acid (see p. 662) may also be used with decided ad- vantage. In cases of chronic suppurative otitis it is well to examine for adenoids, as these growths in the nasopharyngeal vault help to keep up ear discharge indefinitely. The presence of dead bone and granu- lations is also to be considered in the chronic suppurative cases. When the presence of dead bone or granulations is established, the condition calls for radical procedure by a skilled otologist in order to avoid mas- toid and intracranial complications. In fact, cases of this nature should be treated only by an otologist . Because of the ease with which pus may enter the mastoid antrum the complication of mastoiditis is of frequent occurrence in acute aural diseases. Streptococcal infection of the middle ear predisposes to mas- toid involvement. Delay in incising the drum and establishing free drainage in acute otitis is also a factor in not a few cases. Finally, as an underlying cause of mastoiditis should be mentioned the child’s lack of general resistance to bacterial infections. It is not to be forgotten that mastoid disease may be primary or occur synchronously with the development of otitis media. Symptoms.—Mastoid disease may be looked for in all cases in which an elevation of the temperature continues in spite of free discharge through a wTell-opened drum. Tenderness on pressure is a valuable sign, but its absence does not preclude mastoiditis. Prolapse of the posterior superior wall and the rapid appearance of pus in the canal after thorough cleaning are to be looked upon as most important signs. When there is tumefaction and swelling of the soft parts behind the ear (perimastoiditis), the mastoid cells and antrum will almost invariably be found involved. In about 10 per cent, of the cases both mastoids will be involved. Complications.—The complications are sinus thrombosis, jugular involvement, facial paralysis, septic meningitis, and pyemia. We have seen all these most serious complications in not a few cases, and have cause to regard the presence of pus in the mastoid cells or even in the middle ear in children as a matter of serious import. Treatment.—Operation, and that early, is the only treatment for the MASTOIDITIS 664 THE PRACTICE OF PEDIATRICS condition. Children have unquestionably recovered from mastoid disease without operation, but expectant procedures are fraught with great dan- ger and should not be countenanced if the child is in condition to admit of operation. SINUS THROMBOSIS In a small percentage of cases of mastoiditis there is extension of the infection to the lateral sinus. Symptoms.—Sinus involvement will usually be indicated by rapid and wide variations in the temperature. The rise is very sudden, and may reach 106° F. The fall may be correspondingly rapid, and a pecu- liarity of the temperature phenomena in sinus disease is the extent of the fall. The writer lias seen a rise of 10 degrees in two hours, and has repeatedly known the fever to drop to 96° F. A confusing and misleading circumstance in these cases may be the absence of signs of great prostration. When the temperature is high the child appears very ill; when the fever subsides the patient brightens, perhaps plays, and is interested in his surroundings. It is difficult to reconcile the patient’s demeanor with so grave a disease. The mislead- ing behavior, in our observation, has been the occasion of delaying oper- ative measures until such means proved of no avail. Leukocytosis and a high polynuclear count are usually present. In one case, however, the polynucleosis was not above 60 per cent. Bacteremia is usually present. Its absence, however, does not pre- clude sinus disease. Metastases of bacterial emboli, with the develop- ment of septic arthritis, endocarditis, pneumonia, and meningitis, are to be expected when the infection is overwhelming. Treatment.—The treatment is the radical operation, with resection, if necessary, of the jugular vein. Transfusion is a supplementary procedure of great value. XIX. THE TRANSMISSIBLE DISEASES In this group of diseases for purposes of convenience are not included a number of affections elsewhere discussed, the characteristic tendency of each of which is to single out one organ or structural group in the body for attack. The present discussion relates to a less selective group to which the term “tranmissible” is probably more patently applicable. Year by year, however, such designations become less definite and such terms as “in- fectious” and “contagious” have a wider connotation. Diseases Which May Be Transmitted Through Contact.—Syphilis, diphtheria, gonorrhea, stomatitis, tuberculosis, pneumonia, scarlet fever, measles, German measles, mumps, smallpox, chickenpox, pertussis, poliomyelitis, meningitis, acute cerebrospinal meningitis, plague, typhus, influenza, encephalitis. Diseases Which May Be Transmitted Through an Intermediary.— Gonorrhea, typhoid fever, malaria, yellow fever, tuberculosis, cholera, plague, stomatitis, scarlet fever, diphtheria, measles, chickenpox, pertussis, syphilis, typhus, and poliomyelitis. It will be observed that some of the foregoing diseases are trans- missible in more than one way. Syphilis, in addition to being transmissible through association, is transmissible by inheritance. Gonorrhea is transmissible through association and through inter- mediary objects. That the latter mode of conveyance is common is absolutely proved by the spread of the disease in institutions and hos- pitals, through the use of the thermometer or at the hands of attendants. Among the diseases grouped as transmissible through association, in which such transmission is eminently a feature of the disease, are those that usually have been designated as contagious, e. g., scarlet fever, diphtheria, measles, German measles, mumps, smallpox, chickenpox, pertussis and poliomyelitis. Among the diseases transmissible by intermediary means, gonor- rhea has been referred to. Typhoid fever is usually water borne or food borne by flies. Ma- laria and yellow fever are transmitted by the mosquito. Cholera is usually a water-borne disease. Plague may be transmitted through any intermediary which has been in contact with the infected subject. Stomatitis, a comparatively insignificant disease, may be trans- mitted through nipples, pacifiers, or toys that have been in the mouth of the patient. There is quite an unanimity of opinion that scarlet fever, diphthe- ria, measles, chickenpox, mumps, and smallpox may be transmitted from the diseased to the unprotected individual through the agency of an intermediary person or object. Our own observation corroborates this view. At the same time we are sure that such transmission is less frequent than is generally supposed. 665 666 THE PRACTICE OF PEDIATRICS The usual means is through association with an individual who has the disease, perhaps in so mild a manner that it has not been recognized. This is particularly the case with diphtheria, scarlet fever, and polio- myelitis. These diseases, viz., scarlet fever, diphtheria, measles, chicken-pox, pertussis, German measles, poliomyelitis, and mumps, have another fea- ture in common. They may be extremely severe, or so mild that the case is not recognized, and the patient associates as usual with his fel- lows. It is to these mild cases that the spread of the disease is ordinarily due rather than to a transference of the contagium through unusual channels. It has been estimated that 1 per cent, of children in cities have viable diphtheria bacilli in their throats. Scarlet fever, because of the possible variation of its course and the indefinte rash, is overlooked more frequently than any other of the dis- eases of this class. It is not at all unusual for school inspectors to find children with active scarlet fever desquamation in attendance at schools. Abortive non-paralytic cases of poliomyelitis are unquestionably a chief agency in the transmission of this disease. The writer has seen a case of chickenpox in which there were but five vesicles without other sign of illness, and patients with unquestionable pertussis who never whooped. CARE TO BE EXERCISED BY THE PHYSICIAN IN VISITING INFECTIOUS AND CONTAGIOUS DISEASES Physicians in attendance upon contagious diseases, particularly diphtheria and scarlet fever, should exercise reasonable care in their association with other patients. The coat should be removed and shirt- sleeves turned up to the elbows. A gown, or a sheet suitably adjusted with safety-pins, should protect the clothing. History.—Numerous descriptions left by ancient authorities afford evidence that smallpox has existed from the earliest times, in fact long before the Christian era. France and Italy were ravaged by this form of pestilence in the sixth century and England is supposed to have been invaded by the disease as long as one thousand years ago. Prior to the discovery by Jenner of vaccination in 1798 smallpox annually caused thousands of deaths in England, while in less advanced countries the mortality was even greater. For over one hundred years before Jenner’s discovery inoculations had been practised, first in Turkey and later in England and America. The disease, when “engrafted,” was uniformly observed to be much milder than when contracted in the ordinary manner. When thus in- oculated from patient to patient, however, the affection maintained its contagious character, and for obvious reasons the practice had much to condemn its employment. To Sydenham in the seventeenth century was due much of the better understanding of the disease. Not until the proof by Jenner that those individuals previously vac- cinated with cowpox virus were immune to smallpox was the way opened SMALLPOX (VARIOLA) SMALLPOX (VARIOLA) 667 for general and safe immunization. As an example of effective artificial immunization against disease this form of vaccination, even since the time of Pasteur, has remained pre-eminent. Etiology.—Smallpox respects no race, no age, and no sex; even infants seem to possess no natural immunity. The disease is most prevalent in winter. The exact nature of the specific cause remains in doubt, although the work of numerous investigators, including Guarnieri, Councilman, and Prowazek, indicates that the causative organism belongs to the protozoa. Contagion is transmitted by direct contact with skin lesions and body excretions and also through clothing, the virus being extremely viable and persistent. Immunity after one attack is the rule. Pathology.—The most significant changes induced are exhibited by the skin lesions. Councilman has demonstrated that even at the outset these lesions, in spite of their macroscopic papular appearance, are actually vesicular, while the organisms causing the disease are apparently brought to the skin lesions by the blood. In general, the progressive changes exhibited by the cutaneous lesions are indicated by the symptomatology presently to be discussed. On mucous surfaces, ulcerations and erosions take the place of the lesions produced in the skin. Fatty degeneration and focal necrotic areas are found in the viscera. Necrotic changes in the bone-marrow have also been described. Both bone-marrow and blood show a noteworthy diminution in polynuclear cells. Glomerulonephritis, otitis, pneumonia, and corneal ulcerations are among the pathologic conditions which may complicate ordinary small- pox. Incubation Period.—This ranges typically from ten to twelve days, rarely being prolonged to sixteen to twenty days, particularly in the mild forms of the disease. Symptomatology.—In the child the course of the disease, which is practically the same as in the adult, progresses through fairly definite stages. Invasion.—Prodromal symptoms are usually not significant, although chilliness, headache, sore throat, or lassitude may be noted. The onset is as a rule sudden and accompanied by a chill with headache, backache, and a rapidly rising temperature of 103° F. or higher. Not infrequently the fever in children ranges as high as 106° F. The pulse is full and is increased in rapidity, proportionally to the temperature elevation. The tongue becomes heavily coated and the breath foul. Vomiting may be the first symptom and at times is persistent. Convulsions, delirium, and in children coma are not infrequent. Vertigo is occasionally a feature. Before the completion of the initial stage a prodromal rash may appear. This may be scarlatinaform or more often morbilliform and at times is definitely petechial or hemorrhagic. The Eruptive Stage.—The initial stage is superseded with regularity on the third day by a period in which the characteristic phenomenon is the development of red macules in rapidly increasing numbers, which quickly become elevated and papular, “shotty” on palpation. By the 668 THE PRACTICE OF PEDIATRICS fifth day of the disease the lesions become vesicular and even before this they may coalesce. The typical vesicle shows a central umbilication and is multilocular. The eruption is most profuse on the portions of the body showing the greatest skin congestion, particularly the face. By the sixth day the vesicles undergo suppuration and show a deeper areola so that the parts most affected become actually edematous, the eye- lids at times becoming closed. The maturation of the eruption on the face, in keeping with the first appearance of the rash at this site, advances be- fore the development of pustulation on other portions of the body. Re- trogression of the pustules becomes apparent about the eighth day. In the mouth, because of the delicate character of the epithelium, the lesions take the form of erosions or ulcerations. The tongue may be very sore, and the throat so sore as to make swallowing very difficult. During the interval between the onset of the eruptive stage and the development of suppuration abatement in the fever and accompanying constitutional symptoms is the rule, but the fever recurs with the pustular stage at about the fifth or sixth day of the illness, usually, however, in less degree than during the stage of invasion of disease. The blood shows leukocytosis with a relatively high percentage of lym- phocytes. Involution.—Subsidence of tumefaction marks the beginning of retro- gression of the eruption at the end of the pustular stage, the face first showing the improvement. Desiccation and crust formation usually begins about the tenth to the twelfth day of the eruption. Three or four weeks may elapse before desquamation is complete. During the drying stage, itching is a most annoying symptom. Varieties of Smallpox.—Confluent smallpox, as its name implies, in- volves almost the entire body surface. The mortality is high. Petechial and purpuric smallpox are malignant hemorrhagic forms of the disease, variola purpurica being most fatal. The pustular hemorrhagic form is an extreme type. Mild smallpox is today the form most prevalent in the United States. Individuals affected by this type of the infection may not be confined to bed at any period throughout the entire course of the disease. Such cases are marked by a moderate intensity and show a rash which is easily mistaken for a chicken pox eruption. Differential Diagnosis.—The initial symptoms of headache, generalized pain, chill, and fever, with perhaps vomiting, are at times mistaken as indicative of the onset of grip, pneumonia or meningitis, while the pro- dromal eruption may give rise to a wrong diagnosis of scarlet fever or measles. The disease most frequently confused with variola is chickenpox. This is due to the prevalence of smallpox in a mild atypical form because of existing partial immunity in the patient, conferred by vaccination. This, although performed years before the time of the disease attack, may nevertheless afford considerable immunity. In making the differentiation between variola and varicella the follow- ing points are to be kept in mind: In smallpox the rash is particularly abundant on the face, back, and SMALLPOX (VARIOLA) 669 limbs, whereas in chickenpox lesions are distributed variably with a tendency to avoid the limbs and appear on covered areas of the body. Furthermore, the vesicles in varicella are more superficial than in smallpox and are generally unilocular, are never umbilicated, and, unlike those of smallpox, tend to appear in successive crops. Owing to the prevalence of early vaccination variola is relatively rare in early childhood. In doubtful cases the vaccination may be used as a test of great value, successful recent vaccination or successful vaccination after the third day of the eruption being almost positive evidence that the disease under observation is not smallpox. Complications and Sequelae.—Among the most important and fre- quent secondary affections are bronchitis and pneumonia. Edema of the glottis with ulcerative lesions in the throat has been observed. Otitis media, conjunctivitis, and even corneal ulceration are also seen as the outcome of smallpox, while adenitis, nephritis, and pericarditis may de- velop. Cellulitis, boils, abscesses, erysipelas, and even tetanus may result from secondary infection of the skin lesions. Prognosis.—Among children smallpox unmodified by vaccination is particularly fatal. Woody1 has emphasized this fact by recalling that in an epidemic in Montreal during 1884-86 over 85 per cent, of all fatalities were among children under ten years. The hemorrhagic and confluent forms are extremely fatal and in gen- eral the prognosis is considered to be bad proportionately to the char- acter and number of the skin lesions. Treatment.—Prophylaxis.—Vaccination, preferably during early in- fancy, constitutes the only reliable form of prevention. Vaccination should be repeated every five to seven years, although following vaccination in infancy revaccination at puberty and again in the fourth decade has been proved effective in affording lasting protection in all but exceptional individuals. Isolation.—This should be practised most conscientiously with regard to the prolonged segregation, not only of the patient, but of all recently unvaccinated contacts until two weeks at least have elapsed. Quarantine of the patient himself should be strictly maintained much longer until all crusts have been desquamated. General Therapy.—After the stage of onset during which antipyretics and sedatives may be administered with advantage, as in the treatment of grip, hydrotherapy in the form of sponging, packs, and cool baths is of most value. After suppuration is established warm baths may be substituted. Topical applications to the lesions comprise a long list in which tinc- ture of iodin, as an agent of value in shortening suppuration and thus preventing scarring, holds a foremost place. Alcohol, 25 per cent., in boric acid solution, and bichlorid of mercury, 1 : 10,000 solution, have also proved of value. During the late stages various antiseptic ointments are of aid in facilitating desquamation and relieving itching. Mouth-washes are indicated and their use should be supplemented by particular attention to local ulcerative conditions of the gums or tongue. The diet during the acute stage should consist of fluids only. Later 1 Tice, Practice of Medicine, 670 THE PRACTICE OF PEDIATRICS milk toast, ice-cream, stewed fruit, vegetable purees, and simple desserts may be added. In general, the treatment is solely supportive and symptomatic. Nurs- ing in smallpox, as in the conduct of typhoid fever, holds a place of peculiar pre-eminence. During convalescence an out-of-door life and liberal feeding may be supplemented by the administration of appropriate tonics, as in the after- management of severe measles. CHICKENPOX (VARICELLA) Chickenpox belongs to the transmissible diseases, and is usually transmitted by association contact, rarely through an intermediary. The contagium of varicella is present in the fluid contents of the eruptive vesicles, and also in the crusts resulting from the drying of the vesicular contents. Consequently the period of transmissible infection persists as long as any crusts remain on the skin. The specific etiologic factor in this disease is still unknown. Fig. 116.—Deep ulceration in case of dermatitis gangrenosa infantum following chickenpox. Incubation.—The period of incubation is rarely less than eighteen days nor longer than twenty-five days. In the majority of cases it has ranged between twenty and twenty-five days. Symptoms .—Prodromal symptoms are rarely of sufficient severity to warrant complaint or give evidence of illness on the part of the child. In severe cases there may be slight temperature and muscle soreness. The temperature rarely goes above 102° F., usually not over 100° F. The Rash.—The eruption is usually the first important sign of the disease. The back and abdomen are the sites ordinarily involved early. The rash may appear on any portion of the body. It occurs abundantly on the scalp. Usually there are a few spots in the mouth. Not infrequently from the onset the lesions are distinctly vesicular, without any associated skin inflammation, resembling drops of water that may have been sprinkled carelessly over the skin surface. More frequently the rash consists of macules, then papules, and later vesicles resting on well-defined red areolae. At first the vesicles contain clear fluid and vary in size from mere points, scarcely discernible to the naked eye, to lesions § inch in diameter. In a few hours the serum becomes cloudy and purulent. In from twenty-four to seventy-two hours the CHICKENPOX (varicella) 671 fluid is absorbed, leaving the erupted area slightly umbilicated, so that on further drying this forms a crust or scab. These crusts fall off in from one to three weeks, each leaving a distinctly reddish skin area, at the site of which there is sometimes a temporary scar. The rash varies greatly in its intensity. Most of the lesions do not go through the char- acteristic stage just mentioned, and many do not go beyond the papular stage. All stages of the eruption may be seen at one time in any well- marked case, for the reason that the rash appears in successive crops, of which there are usually three, although there may be more. The first crop may be in the scabbing stage when the third or a later crop appears. The amount of rash is extremely variable. Illustrative Cases.—In 1 case there were but three vesicles. In 3 others, all institution cases, so severe and extensive was the rash that it resulted in a gangrenous dermatitis consisting of clearly punched-out ulcers. The gangrenous area coalesced, with destruction of large areas of the skin surface. These 3 cases were all fatal. Duration.—The duration of an attack, from the beginning of the period of eruption until the skin clears, is about three weeks. In mild cases the skin may become clear in two weeks. Quarantine.—The child should be kept in quarantine and not al- lowed to come in contact with unprotected children until three weeks have elapsed, or until the skin is free from crusts. Complications.—Erysipelas was a complication in 2 cases; gangrenous dermatitis in 3. Nephritis, although rare, may develop. One of the most severe cases of acute glomerular nephritis treated in a long period occurred as a sequel of chickenpox. Furunculosis, due to infection by scratching, is a quite frequent complication in children’s asylums. Prognosis.—The prognosis is good. It is very unusual for the most delicate child to succumb to the disease. The institution infants who developed gangrenous dermatitis (Fig. 116) and a phys- ician’s child who developed erysipelas at the site of a chickenpox lesion presented the only fatal cases that have come under our observation. Treatment.—Chickenpox is a disease for which very little treat- ment is required. During the eruptive period, and until the period of vesiculation is passed and the crusts have formed, the child should be kept in bed. During the stage of active eruption the tub-bath should be omitted. Instead, gentle sponging with a tepid solution of boric acid—2 heaping tablespoonfuls of boric acid to | gallon of boiled water—will answer the requirement of cleanliness for a few days. After the daily sponging, and several times during the day, the areas affected should be anointed with boric acid ointment made with cold cream as follows: I£. Mentholis gr. x Pulveris acidi borici gr. c Unguenti aquae rosse 5ij-—M. The ointment effectually relieves the itching, and doubtless is of value in preventing local skin infection through scratching. An equally effective remedy, but one less agreeable for domestic use, is a lotion of 672 THE PRACTICE OF PEDIATRICS 5 per cent, ichthyol and sterilized olive oil. This is to be applied to the entire body twice daily after the bath. Objections to its use are the odor and the staining of the clothing and bed-linen. Permanent scars at the site of the vesicles are so rarely seen that no special precautions are required on this account. MUMPS (EPIDEMIC OR SPECIFIC PAROTITIS) Mumps is a specific infection of the parotid glands. Cocci have been isolated from the inflamed parotid gland in cases of mumps, but their specificity has never been proved. More recent studies point to a filtrate virus as the probable cause of the disease (Woll- stein). The exact nature of the virus has not yet been determined. Mumps affects chiefly the runabout and school children. Infants and very young children are rarely affected. Transmission.—The disease may be conveyed by direct contact or through intermediary individuals, books, toys, or clothing. Incubation.—The period of incubation is long—from two to three weeks. Duration.—The duration of the disease from the commencement of the swelling until it has completely subsided is from ten days to two weeks. Quarantine should be maintained until the swelling has entirely sub- sided. Pathology.—As the great majority of cases are not fatal, it has been difficult to study the pathology of the disease. The pathologic changes that are known to occur are ordinarily limited to the salivary glands. There is edema and cellular infiltration of the connective tissue around the ducts and between the acini, while the glandular epithelium is often swollen and cloudy. The infiltration is most marked around the ducts. When mumps affects the testis, the inflammation assumes a paren- chymatous form, and when the epithelial degeneration in the tubules is severe, atrophic changes in this gland may follow. Occasionally the orchitis is accompanied by urethritis, edema of the scrotum, and in- guinal adenitis. Ovaritis, mastitis, and acute pancreatitis complicating mumps have been observed. Symptoms.—Usually one gland is affected at first, and the gland first affected is usually the one most prominently involved, the second gland rarely reaching the size of the first and subsiding much earlier. In some cases, three or four days intervene before the second gland shows the characteristic swelling. The submaxillary glands may be involved in the process, but usually escape. In one patient the submaxillary glands alone were involved. In another child three years of age both parotids and submaxillary glands and the sublingual gland showed massive involvement. Involvement of other salivary glands than the parotid is more fre- quent during cold weather. There may be prodromal symptoms of fever and languor. Diffi- culty is experienced by the patient in working the jaws. Not infrequently MUMPS (EPIDEMIC OR SPECIFIC PAROTITIS) 673 there are sharp neuralgic pains and pains referred to the ear. An eleva- tion of the temperature is usual during the acute stage, although this may not exceed 100° F. In most instances it does not exceed 102° F. If the glands are involved separately at two or three days’ interval, there may be two distinct rises in temperature. The temperature is rarely sufficiently high to demand special treatment. Diagnosis and Differential Diagnosis.—The patient presents a char- acteristic picture, the face taking on a rotund, rather ludicrous appear- ance, produced by no other malady. Acute adenitis of the lymphatic glands at the angle of the jaw is most frequently mistaken for mumps. Mumps, on the other hand, is not often mistaken for adenitis. In history taking not infrequently one is told that the child has had two or three attacks of mumps, which means that the child has had perhaps Fig. 117.—Mumps. one attack of mumps, the others having been acute adenitis. In mumps the swelling, by involving the parotid, which it will be remembered is in front of and below the ear (Fig. 117), displaces the lobe upward and outward and completely fills the depression posterior to the lobe. In adenitis (Fig. 80) there is usually a well-marked depression between the swelling and the adjoining parotid. Abdominal pain and vomiting in mumps should suggest pancreatitis rather than appendicitis. Complications in mumps are exceedingly rare before puberty. Or- chitis may occur in boys and ovaritis in girls, but only very exceptionally if the patient is kept in bed. Infection of the parotid other than that produced by the specific poison of mumps is extremely rare. Abscess as a complication due to a mixed infection has been reported. Nephritis is an occasional complication. One such case occurred in a boy two years 674 THE PRACTICE OF PEDIATRICS of age. Complicating pericarditis, endocarditis, and pancreatitis have been reported. Prognosis.—The prognosis is good. We have never known a second attack, a relapse, or a death from the disease. Treatment.—During an attack the child should be kept in bed until the temperature is normal, and should remain in the house until the swelling has entirely subsided. He should receive a reduced diet of broths, gruels, and milk, as in any illness with fever. Fruits and acids should not be given because of the discomfort they occasion. Unless the bowels move daily without assistance, citrate of magnesia or a Seidlitz powder should be given. Warm applications at times relieve the pressure and discomfort. Flannel moistened with warm camphorated oil and bound to the parts has been acceptable to many patients. WHOOPING-COUGH (PERTUSSIS) As an infectious disease of importance, pertussis may be classed with diphtheria and scarlet fever. It is probably the cause of more deaths today than is any other infectious disease. It does not kill directly through a specific poison, as do diphtheria and scarlatina, but on account of its prolonged course and its many complications is equally effective as a life destroyer. History.—Whooping-cough has existed from early times, under such names as “tussis perennis,” “tussis infantum,” “chink cough,” “chine- cough,” and “king’s cough.” In a treatise published in 1773 William Butter, of Edinburgh, aptly described “kinkcough” as “a quick and nu- merous succession of violent, short coughs followed by a long, strait, and generally shrill inspiration, which coughs and inspiration are repeated without intermission for many seconds or often some minutes and often terminate in the vomiting of phlegm.” Robert Watt, writing in 1813, stated that “next- to the smallpox formerly, and the measles now, chin- cough is the most fatal disease to which children are liable.” The seat of the affection was variously placed by the early writers in the nervous system, in the digestive organs, and in different portions of the respiratory tract. Butter believed that “miasms generated in the guts, act on the nerves” and “increase irritability.” Further in- formation is proffered in statements that “measles render the kinkcough very dangerous”; “smallpox either cures or palliates”; and that “hemlock cures the kinkcough in a week.” A critic of the hemlock therapy ironically recalled that “the flesh of fried mice . . . has been in vogue as a specific.” Certain it is that even in very recent years no disease has been treated by remedies of wider diversity. Partial explanation of this fact undoubtedly rests upon the frequent association of whooping-cough with other diseases, as well as upon the varying therapeutic requirements of its more common complications. Bacteriology.—The bacillus described by Bordet and Gengou in 1906 is at present generally accepted as the cause of pertussis. The bacillus is a short, ovoid, polex, regular, non-motile rod, which does not stain by Gram’s method. It is best isolated upon plates of potato- WHOOPING-COUGH (PERTUSSIS) 675 agar mixed with rabbit’s blood, as described by Bordet and Gengou, but later generations grow readily upon plain agar. The bacillus is present in the sputum in enormous numbers, and almost in pure cultures on the first two or three days after the onset of the whoop, and it may be found several days before the spasmodic stage begins (Wollstein). At the end of the first week of this stage, however, other bacteria, such as pneu- mococci and staphylococci, have usually become so numerous that isola- tion of the bacillus is impossible. Agglutination reactions with the pa- tient’s serum are irregular and unsatisfactory. Complement-fixation tests have been reported positive, but they are not regularly so. Jochmann and Krause found the influenza bacillus in the sputum of pertussis patients in 100 per cent, of the cases they studied. In children who have died during the spasmodic stage of an attack of pertussis the Bordet-Gengou bacillus has been found in the heart’s blood and also in the lungs, where Bacillus influenzae is usually present as well. Transmission, as with most of the communicable diseases, is by means of direct contact. That pertussis may be conveyed through the medium of clothing, a book, a toy, or a second person is exceedingly doubtful. Extreme youth offers no protection as in the case of scarlet fever or diphtheria. Infective Period.—The disease may be transmitted from the begin- ning of the catarrhal stage. The duration of the period of infection is not known. It probably continues in the average case until the child ceases to whoop. When pertussis breaks out in a school or in an institution for chil- dren, prevention of an epidemic is practically impossible, because the disease is infectious during the early catarrhal stage, which lasts from one to two weeks. During this time the only symptom is a cough and perhaps a slight degree of bronchitis, such as exists with a common cold. Susceptibility.—The previous state of health appears to exert no influence upon the patient’s susceptibility. The strong and the deli- cate are alike predisposed to infection. The very young and the adult are less liable to take the disease than are children between the fourth month and the third year. This is the most susceptible period of life. Cases have been reported in children one week old. Any other concur- rent infectious disease exerts no influence upon the duration of the per- tussis. The theory has been advanced that the advent of diphtheria or scarlet fever during an attack of pertussis shortened and modified the course of the disease, but experience does not corroborate this belief. Other affections which occur during an attack simply increase the burden to be borne by the patient. The largest number of cases develop during the warmer months—from May to November. This circumstance may be accounted for in part by the fact that during the warm period of the year the infected child comes more frequently in contact with unpro- tected neighbors. The same circumstance, however, tends to disprove that catarrhal affections of the respiratory tract predispose to the disease, since respiratory affections in the young during the warmer months are notably rare. The normal healthy mucous membrane offers no greater 676 THE PRACTICE OF PEDIATRICS resistance to pertussis than does that which is affected by disease. In the early stages of pertussis there is not simply a bronchitis, but a catarrhal process due to a specific infection. Interesting observations relative to susceptibility to measles and pertussis were made by Biedert. After a lapse of sixteen years both these diseases broke out in a German village at about the same time. There were 401 children in the village under fourteen years of age. These children had never been far from home, and not one of them had had either measles or pertussis. Of this number, 344 became ill with measles and 366 with pertussis, 340 having both diseases at once. The suscep- tibility of these unprotected children to pertussis was, therefore, 95.5 per cent.; to measles, 85.8 per cent. Of those who escaped pertussis, 7 were under five years of age, 4 between five and ten years, and 9 between ten and fourteen years. Pathology.—There is very little characteristic pathologic change in uncomplicated pertussis. There is an inflammation and infiltration of the mucous membrane of the larynx and upper trachea, which is doubt- less the seat of the specific infection. Mallory has affirmed that the specific lesion is the presence of Bacillus pertussis between the cilia of the epithelial cells of the trachea and bronchi. Incubation.—The period of incubation is difficult to determine. It seems to range from seven to fourteen days. Symptoms.—At the outset the cough may be short, hard, and of a paroxysmal nature. Usually, however, the cough is in no way char- acteristic and does not differ from that which accompanies bronchitis or tracheitis. Instead of improving under treatment, this symptom becomes more severe and more frequent. The child coughs more at night, usually, than during the day. In a week or ten days, rarely less than a week, the characteristic whoop occurs. Fever depends on the degree of associated bronchitis. A leukocytosis is common throughout the disease. The large mon- onuclear cells are characteristically increased in number and a moderate degree of eosinophilia is common. Vomiting is a frequent associated symptom. It is mechanical in origin, not dependent primarily on gastric disturbance. For this reason the child may eagerly take and retain food almost immediately after vomiting. As the disease progresses the paroxysms increase in frequency and may occur even to the number of 50 or more daily. Duration.—The paroxysmal stage remains at its height for a period ranging from one to four weeks. Beginning improvement is always marked by a diminution in the frequency and severity of the seizures. Complications.—The complications of pertussis are many, and account for the fact that the disease is so destructive to life. The most fatal com- plication in winter is bronchopneumonia; in summer, gastro-enteric disease. Convulsions are not an infrequent complication, and may be fatal. Mal- nutrition often follows a severe attack in a delicate, bottle-fed child, thus paving the way for intercurrent disease. Tuberculosis not infrequently follows a prolonged attack of pertussis. Blindness, deafness, and motor disturbances have all been observed during attacks of pertussis, and have been followed by complete recovery. These cases may be explained as WHOOPING-COUGH (PERTUSSIS) 677 follows: During a severe paroxysm the cerebral circulation is greatly disturbed, and as a result of an extreme congestion or venous hyperemia there is a disturbance of nutrition in certain portions of the brain. Epis- taxis is frequent and in rare instances cerebral hemorrhage with resulting permanent paralysis has occurred. On the cessation of the paroxysm these symptoms all disappear. Diagnosis.—The diagnosis of pertussis is most difficult in the early stages, before the whoop or convulsive paroxysm develops. Even a spasmodic cough does not always mean a developing pertussis. In rachitic children, and in those in whom the nervous element is prominent, the cough of an ordinary cold is often of a decidedly par- oxysmal character, especially when there is an acute or subacute laryn- gitis. The cough, however, if more troublesome at night, favors a diagno- sis of pertussis. If the diagnosis is correct, the cough grows steadily worse and resists the usual treatment of colds. The mild cases are also difficult of diagnosis. Illustrative Cases.—Two patients, aged eight and ten years respectively, went through an attack of pertussis with but two or three severe paroxysmal coughing attacks. Two other cases seen in private practice also show how mild may be the course. The patients, brother and sister, aged six and eight years respectively, commenced coughing about ten days after exposure. The cough was paroxysmal, with from three to five seizures in twenty-four hours. The boy whooped only three times during the entire course of the disease; the girl did not whoop at all. Vomiting never occurred with a paroxysm. Both patients coughed for six weeks. They had neither adenoids nor bronchitis. Often the very young and the very delicate do not whoop, even dur- ing a severe attack. Among the severe cases convulsions and hemor- rhage from the nose, ears, and eyes are seen from time to time. A very severe seizure in a girl nine months old was followed by small extravasations of blood into the skin of the entire body. Differential Diagnosis.—In all cases of severe cough of uncertain origin the nasopharyngeal vault must be examined for adenoid growths. In young children this can be properly done only by the use of the index- finger. The presence of enlarged bronchial glands, whether of tuberculous origin or the result of prolonged respiratory infection of the streptococcus or influenzal type, may also readily account for persistent cough of the pertussis character. x-Ray is of great value in the differentiation of such cases. As a general rule, the presence of a persistent cough with a paroxysmal tendency, in the absence of local respiratory irritation of any nature, and accompanied by eosinophilia, is very suggestive in a suspected case. Prognosis.—Pertussis in children under eighteen months of age must ever be regarded in a serious light. Delicate and rachitic children should be carefully guarded against the disease. Bronchopneumonia and gastro- enteric troubles are the most frequent complications among this class of children. The majority of healthy children over eighteen months of age bear whooping-cough without great inconvenience. 678 THE PRACTICE OF PEDIATRICS Breast-fed babies tolerate the disease in the early months of life far better than do those artificially fed. Treatment.—The use of drugs in whooping-cough has always been more or less of a disappointment. By their use, however, the par- oxysms may be lessened in number and severity and the illness may be made easier for the patient to bear, which of course is important. Good results have been obtained by the use of antipyrin and bromid of soda in combination as follows: For a child eight months of age, \ grain of antipvrin with 2 grains of bromid of soda are given at two-hour intervals—six doses in twenty- four hours; for a child of fifteen months, 1 grain of antipyrin and 2f grains of bromid of soda at two-hour intervals—six doses in twenty-four hours; from the fourth to the eighth year, 2 grains of antipyrin and 5 grains of bromid of soda at two-hour intervals—six doses in twenty-four hours. Quinin has been used in a large number of cases in both private and outpatient work. Great benefit may be derived from its use if a large amount can be given. Its administration, however, is attended with difficulties. Twelve to 20 grains in twenty-four hours are required for pronounced results in children from two to six years of age, and the ad- ministration of such a large amount is not favorably received by many parents. Again, our inability to make the drug palatable is a serious drawback for any age, and almost excludes its use in the very young; furthermore, in the very young and delicate quinin may derange the stomach and produce vomiting. A good form of solution to use is that of bisulphate in Yerbazin, or a similar preparation “Coca-quinin” (Lilly). In older children, when quinin can be given in sufficient quan- tities in capsules, the decrease in the number and severity of the parox- ysms is sometimes surprising. Codein is to be used in the most severe forms of pertussis when other means fail to relieve the patient. One of the most troublesome features of the disease in infants and young children is the wakefulness at night caused by repeated attacks of coughing and vomiting. When the child cannot sleep, codein is advisable independent of the other treatment, whatever it may be. For a patient five years of age | grain is to be given at bedtime and repeated during the night whenever the paroxysms require. For a child from eight to twelve years of age, l grain may be given at bed- time and repeated twice if necessary. For a child from two to three years of age, iV grain may be given and repeated not oftener than twice during the night. The drug should not be continued longer than a week or ten days. We have never seen unpleasant effects follow its use. Interrupted Medication.—It will be observed that the drugs of value in whooping-cough are the sedatives. For the reason that by the pro- longed use of sedatives their effect is lost, it has been found wise to use what may be called “interrupted medication.” For five days the antipyrin and bromid of soda are given. Full doses of quinin only are then given for five additional days, at the end of which time the antipyrin and bro- mid are resumed. In this way, giving the drugs five days each, one may continue with advantage for a month or six weeks. It is rarely necessary to continue the treatment longer than six weeks—usually from three to WHOOPING-COUGH (PERTUSSIS) 679 four weeks is sufficient. Of course, the child will whoop after that time, but the active stage of vomiting and severe paroxysms will be over. If the vomiting can be controlled in an attack of pertussis, and if the patient can obtain sufficient sleep, much has been accomplished. What has already been suggested should be emphasized: Do not begin the drug treatment of whooping-cough, whether by the administration of quinin, antipyrin, or other remedies, until the spasmodic stage is at its height. If a sedative is given as soon as a diagnosis is made, by the time the disease reaches its height tolerance will have become so established that the drug will have lost not a little of its sedative action. If medicines must be given during the earliest stage, a placebo may be used. Fresh air is of immense value as a means of relief in whooping-cough, regardless of the method of treatment followed. We are told that the child rarely coughs when out-of-doors, but commences as soon as he is brought into the house, which is usually overheated and badly ven- tilated. In nearly all cases the cough is worse at night. This may be ex- plained in part by the absence of proper ventilation in the sleeping apart- ment. A child who for any reason must remain indoors should not be allowed to remain constantly in one room. There should be two rooms and every window in the one not in use should be freely open. The liv- ing room and sleeping room should be kept at a fairly even temperature— from 68° to 70° F. Vaccine.—Our opinion as to the value of vaccine in pertussis has under- gone a series of changes. We confess to periods of enthusiasm and again to those of doubt, which implies that as a remedy vaccine is variable in its apparent effects. It is most difficult to judge whether a remedy is adequate when the improvement noted may be explained in several different ways. We have seen what appeared to be brilliant results di- rectly due to vaccine, although repeatedly following its use no response whatever has been apparent. It is to be remembered that whooping- cough varies greatly in its severity and response to ordinary treatment. For prophylactic purposes two doses are usually given, the first injection consisting of 1,000,000,000 organisms and the second of 2,000,000,000 given forty-eight hours after the first. Injections for curative purposes are ordinarily given at two-day intervals to the number of four or five in all, the dosage ranging from 500,000,000 at the first injection to four to six times this amount at the last treatment. Freeman has laid emphasis on the importance of employing only freshly prepared vaccine. By numerous experienced observers preference is given to a glycerol vaccine. Quarantine in whooping-cough is particularly difficult, but in some adequate degree should be maintained, even if the precaution taken con- sists only in making the patients wear an arm band labeled “whooping- cough.” A fair rule is to isolate the child during the spasmodic stage and at least two weeks after the whooping begins. Practical success in limiting the transmission of the disease has been attained by attempts to keep well children away from those with sus- picious coughs, rather than by actual isolation of the latter. 680 THE PRACTICE OF PEDIATRICS MEASLES By some writers measles is credited with an antiquity as great as that of smallpox, but the fact that measles was long confused with other exanthemata renders it doubtful whether descriptions over two cen- turies old should be accepted. Measles has always been one of the most rapidly advancing of epidemic diseases. In communities long unaffected, such as Iceland and the Fiji Islands, it has attacked the greatest numbers and developed the highest virulence. In the years 1834 to 1836, and 1842 to 1843, nearly the whole of Europe was invaded. Buxton, whose elaborate little monograph, published a century and a quarter ago, still affords much of value, said: “Those who die of measles generally receive their death by a great flux of serum to the lungs.” Cer- tain it is that bronchopneumonia has always given to measles an im- portance out of all proportion to its immediate severity. Transmission.—Measles is the most readily transmitted of all the communicable diseases. A very few seconds’ exposure is all that is neces- sary. Very few of the human race escape. The disease is transmitted by , direct infection. Transmission through an intermediary is not of frequent occurrence. We have never known a proved case. The disease may be transmitted from the beginning of the earliest catarrhal symptoms, which become manifest two or three days before the appearance of the rash. The most infective period is during the first four or five days; how much longer it may continue is unknown. Etiology.—Goldberger and Anderson were able to produce measles in rhesus monkeys by inoculating them with the blood of human patients with the disease. These investigators proved that the blood in measles is infected before the appearance of the rash and during efflorescence of the eruption, while the infectivity decreases twenty-four hours after the eruption has appeared. The buccal and nasal secretions are also infective at the time of the appearance of the eruption and for forty-eight hours afterward. The desquamating scales, on the other hand, were not found infective. The nature of the virus has not been proved, but it is fil- trable through a Berkefeld filter, resists drying for twenty-four hours, and becomes inert after fifteen minutes’ exposure to 55° C. Lucas and Prizner confirmed the work of Anderson and Goldberger, and showed further that the inoculated monkeys develop Koplik spots just as do human subjects. Blake1 has successfully transmitted measles experimentally in monkeys through a considerable series of animals by nasopharyngeal washings, tissue emulsion and blood, with the resulting lesion histologically similar to measles in man. Age.—No age is exempt. In scarlet fever and diphtheria, nature surrounds the very young with a certain degree of immunity. Numerous young infants are, however, susceptible to measles, although this disease almost never occurs in those under three months of age. According to Herman2 infants under two months of age whose mothers have had measles are absolutely immune, although practically all after the ninth month contract the disease on exposure. 1 Francis G. Blake, Measles Experimentally Produced, Arch. Ped., 38, 1921, pp. 90-102 2 New York State Jour, of Med., 23, No. 10, October, 1923, pp. 404-407. MEASLES 681 Incubation.—The period of incubation ranges from seven to four- teen days. It is rare for the disease to develop after the tenth day fol- lowing exposure. A few cases develop, however, as late as the fourteenth day. Symptoms.—In marked contrast to scarlet fever, measles is fairly constant in its manifestations. Very severe cases and very mild cases are encountered. Institutional children have measles much more sever- erely than do private patients, and the former cases are much the more fertile in complications. This is because of the natural disadvantages which an institution necessitates, no matter how well it is conducted. The complications are more frequent because of the more frequent pres- ence of secondary infection to produce the complications. The Eyes.—The first manifestation of the illness is a coryza with mild conjunctivitis. The eyelids become swollen and reddened at the margins. There is photophobia. Cough.—A cough is present from the beginning or develops in a short time. The cough is hard, teasing, and, early in the attack, without bronchial secretion. Occasionally the cough is hoarse and croupy, but this is of rare occurrence. Nervous Manifestations.—Headache is not uncommon. Convulsions occur very rarely, and when present are usually due to indigestion. The child is very restless and unhappy until the eruption is well developed. Buccal spots, described by Filatow and by Koplik (see Plate II), preceding the exanthem by three to five days are pathognomonic. The Rash.—The characteristic rash usually makes its appearance about the ears and over the face, neck, and upper portion of the chest. Thence it spreads to the entire body, the last portions involved being the feet and hands. In its disappearance, the rash follows the same order. It consists of red papules and macules of irregular shape and of variable size. Early in all cases, and throughout most mild cases, there are areas of uninvolved skin between the erupted areas. In severe cases the areas of eruption coalesce so that the face, trunk, and limbs or the entire skin surface may present a livid, deeply congested appearance. The face, covered with the diffuse rash, swollen and edematous, with the swollen eyelids closed and secreting, and the thin, watery nasal discharge presents a picture seen in no other disease. The rash is sometimes quite irregular in the time of its appearance after the onset of symptoms. It may occur very early, coincident with the onset of the catarrhal symptoms, or it may be delayed for a week. The eruption requires from three to six days to complete development. Temperature.—Pronounced fever does not ordinarily develop until the appearance of the rash. Both the temperature and the rash reach their greatest intensity at the same time. Rarely there is a prodromal fever for a few hours which may reach 103° to 104° F. This fever subsides quickly and the indications are that the exposed child will not develop the disease. Within forty-eight hours, however, or less, the temperature again begins to rise with the appearance of the rash. In cases of this nature difficulty has been experienced at the outset in persuading par- ents of the necessity of keeping the child in bed, or even in the house, as the illness is looked upon by the family as a cause of false alarm. 682 THE PRACTICE OF PEDIATRICS Diagnosis and Differential Diagnosis.—The diagnosis in most cases of measles is not difficult. A mild case may closely simulate one of se- vere German measles. The presence of Koplik spots (see Plate II) on the buccal mucous membrane, the conjunctivitis, and cough are usually sufficient to mark the case as one of true measles. There are no other skin manifestations that simulate those of measles sufficiently to occasion confusion. Complications.—Children with measles almost always have some bronchitis. In fact, a mild degree of bronchitis occurs so regularly that it may be looked upon as part of the disease. Bronchopneumonia is the most frequent complication, because the diseased mucous membrane of the respiratory tract becomes a fertile field for infection with pneumococcus and other pathogenic bacteria. The mortality in institutions for children with measles is always large, because of the complication of bronchopneumonia. In an epidemic of measles thus complicated, in a New York institution for children, there was a mortality of 40 per cent. In a series of 3080 cases of measles reported by Mixsell and Giddings1 from the service of the Willard Parker Hospital there were 826 cases of pneumonia, 26.8 per cent., with a mortality of 424, 51.33 per cent. Both lobar and bronchopneumonia were included. Otitis.—Acute, simple, and suppurative otitis is a fairly frequent complication. Its presence should be suspected when the temperature is continued and does not subside with the disappearance of the rash. The absence of pain does not mean that the ears are normal. In a large percentage of our cases of suppurative otitis in young children pain has been absent. Nephritis is a very rare complication. We have seen but one case. Adenitis is a rare complication. Recurrence or Second Attack: One recurrence after a two-year interval was observed in a girl seventeen years of age. The second attack was very severe, and followed by a moderately severe neph- ritis. The family, most intelligent and reliable people, insisted, moreover, that the girl had had measles in childhood, together with other members of the household. If such was the case, she had three attacks of measles. A brother of the patient also had two attacks of the disease. Prognosis.—The prognosis is good in the cases in which pneumonia does not enter. We have never known a fatal uncomplicated case of measles. Treatment.—Serotherapy .—A review of this form of treatment in its application to measles has been made by Ratnoff.2 The method has been developed since 1915 by a number of investigators working inde- pendently, and since 1919 has been standardized by Degkwitz. Serum obtained from the blood of children seven to fourteen days after the establishment of convalescence from measles is administered subcutane- ously to exposed children, if possible four days after the known exposure, in dosage of 2 to 5 c.c. The immunity thus conferred is undoubted. In a few cases symp- 1 Southern Med. Jour., February, 1923, pp. 90-94. 2 Serotherapy in Measles, Arch.

MEASLES 683 toms of mild abortive measles develop in the exposed subjects treated with the serum, but in most instances no signs of the disease are to be noted. In Ratnoff’s series of more than 100 cases no “single typical fully developed case of measles” occurred. Degkwitz obtained the most potent protective serum from adult convalescents. There is ample evidence also from the consistent success now obtained by the New York Health Department to warrant the wride-spread adop- tion of this method of prophylaxis, provided precaution be observed that the serum be taken from subjects free from all constitutional disease other than measles. The Wassermann and tuberculin tests should be employed in fulfilling this precaution. The duration of the immunity conferred is variable and apparently greater in the cases in which the injections are given six days after ex- posure than in those receiving the treatment earlier. The evidence indicates that lasting immunity is not conferred, although the possibility of reinforcing temporary immunity by later injections has already been the subject of study. General Management.—The popular conception of the management of measles is that the patient should be warmly wrapped, given hot drinks, and kept in a warm room with little or no ventilation. An attack of measles renders the child temporarily very susceptible to bronchopneu- monia. The younger and more delicate the child, the greater the danger. The darkened room, with its closed windows and dust, the extra wrap- pings, with the resulting failure of heat radiation, the reduced vitality, and the resulting loss of appetite do much to prepare the way for an infection of the respiratory tract, which so often occasions broncho- pneumonia. If to a case of this nature whooping-cough be added, we have, with few exceptions, a hopeless condition. A child ill with measles should be comfortably clad in the usual night- clothes and kept in bed. No extra wraps are required, nor is it desirable to keep the room warmer than is customary—68° to 70° F. being a suit- able temperature. There are many gradations of light between glaring sunlight and utter darkness. Both are extreme and one almost as un- desirable as the other. It is desirable that a window-shade of dark green be lowered within one foot of the window-sill. A light brown or drab shade should be lowered completely. If the shade is white, or of a very light color, and not supplemented by a curtain of dark material, it will be necessary to exclude the bright light by some other means. The child, if old enough, may dictate the degree of light, inasmuch as any intelligent child will know when the light is painful. Feeding.—For the bottle fed, the milk mixture should be diluted at least one-half by adding boiled water, and the same quantity given as in health. The appetite in the early stage of measles is practically ab- sent, so that little or no food is taken. Patients may be given water to drink freely at a temperature not lower than 50° F. For “runabout” children, eighteen months of age and over, the diet as suggested for the sick (see p. 154) should be given. Bowel Function.—There should be one evacuation of the bowels daily. An enema should be given when defecation does not otherwise take place. The urine should be examined every second day. 684 THE PRACTICE OF PEDIATRICS The Eyes.—During the waking hours the eyes should be generously bathed every hour or two with a 3 per cent, solution of boric acid applied with old linen or cotton, which is afterward destroyed. The Ears.—Otoscopic examination should be made every second day until the case is discharged. In the event of a sudden rise in tem- perature during convalescence, which cannot be explained by the con- dition of the intestine, lungs, or throat, such an examination should be made by an expert. Baths.—The temperature of uncomplicated measles is rarely high enough to call for special measures. If it should have a tendency to continue about 104° F. after the rash is well developed, and the child be uncomfortable and restless, a tepid sponge-bath of ten or twenty minutes’ duration may be given. Whether the fever demands bathing or not, the patient should be sponged once a day with tepid water at 100° F. After the drying an application of cold cream, liquid petrolatum, or olive oil should be made to the entire body. This is to be given for the sole reason that it relieves the itching, induces sleep, and thus enables the child to pass through the disease with less discomfort. Delayed Rash.—Now and then a case is encountered in which the rash is slow in appearing. The temperature is high—104° to 105° F. —the skin hot and dry, and the child very uncomfortable, perhaps de- lirious. In such an event a hot bath—105° to 110° F.—of from three to five minutes’ duration, often brings out the rash and greatly relieves the symptoms, which may have been of an urgent character. On re- moving these children from the bath care must be exercised to keep them wrapped for fifteen to twenty minutes in a blanket which has pre- viously been warmed. The cough during the active period of the attack is one of the annoy- ing features of the disease, for which some relief must be attempted, par- ticularly if the child is kept awake at night. The ordinary expectorants alone are of no service in treating the cough of measles. Only a sedative will give relief. To a child six months of age from 5 to 8 drops of paregoric may be given, and repeated if necessary after an interval of twro hours. The following combination of paregoric and sweet spirits of nitre is often of service: 1$. Tincturse opii camphoratae gtt. x Spirit us aetheris nitrosi gtt. iij M. Sig.—One dose; to be repeated every two or three hours (for a child of eighteen months or older). From the first to the second year, 10 to 15 drops of paregoric or \ grain of Dover’s powder may be given at two-hour intervals, if required. Usually but two or three doses of the sedative will be necessary during the night. Should the paregoric or Dover’s powder be objectionable because one may dislike to give opium to young children, from 3 to 4 grains of sodium bromid in 2 drams of water, repeated as required every hour or two, will be of service for a child under two years of age. From the second to the fifth year 1 grain of Dover’s powder, or from 15 to 25 drops of paregoric, or 1/10 to 1/6 grain of codein, may be given at intervals of from two to four hours. GERMAN MEASLES (ROTHELN; RUBELLA) 685 If bronchitis develops sufficiently to require treatment, as it does in at least one-half the cases, the means for the management of bron- chitis suggested on p. 343 will be found useful. The temperature of a child ill with measles should be taken three times daily, and the lungs and heart should be examined every day. Vapor.—It is excellent practice to keep the air of the sick-room moist- ened with vapor during the entire illness. The benefits are twofold: Vapor relieves the cough, being more agreeable than dry air to the con- gested mucous surface during the early stage; and it prevents the free circulation of dust, the danger of which has already been referred to. If the room is carpeted, it should be well sprinkled with water before sweeping. If, fortunately, the floor is bare, the broom can be dispensed with, and a damp cloth used instead. Fresh Air.—Not only should the air of the sick-room be vapor-charged, but it should be frequently changed through proper ventilation. Quarantine.—The length of quarantine is usually seven days from the onset. In some communities an isolation period of twenty-one days is enforced upon exposed children. GERMAN MEASLES (ROTHELN; RUBELLA) German measles is a disease of the runabout and school-child, rarely- occurring in infants. It is one of the mildest diseases of the transmissible class. Etiology.—The specific etiologic agent of German measles is quite unknown, but that it is not identical with that of either measles or scarlet fever is evidenced by the fact that an attack of rubella does not pro- tect against either of these diseases. Transmission is by direct contact. We have never had proof of the transfer through an intermediary and have never known of a second attack in the same patient. Incubation.—The period of incubation is from two to three weeks. Symptoms.—The first symptom is usually the rash. The temper- ature rarely goes above 101° F. In a very few cases it rises to 103° F., usually at the onset of the illness. The catarrhal symptoms are negligible. There is rarely more than a slight injection of the conjunctiva. The rash is not only the first manifestation of the disease, but it re- mains the principal evidence of the infection. The eruption closely resembles that of measles, and differentiation between the two diseases from the standpoint of the rash may be difficult. It usually appears first about the ears and neck and spreads rapidly. The eruption at first is distinctly smaller and less crescentic than that of measles; it is papular and varies from a faint red to a deep red color; rarely it is distinctly punctate. When this is the case, the erupted areas may coalesce, pro- ducing a diffuse blush not unlike that of scarlet fever. The eruption is usually very temporary, lasting from one to three days and disappearing after the order of its appearance, leaving the face and the neck first. There is no resulting pigmentation or discoloration of the skin, such as may occur in true measles. There is no involvement of the buccal surfaces except for a slight 686 THE PRACTICE OF PEDIATRICS punctate red rash which may be seen on the soft palate early in the dis- ease. Lymphatic Gland Enlargement.—Enlargement of the glands at the angle of the jaw and the post-cervical glands, particularly the latter, occurs so consistently that this condition may be put down as one of the prominent symptoms of the disease. The glandular involvement, however, is very slight, and disappears in from two to four days. The glands in the axilla and groin very rarely show involvement. Desquamation.—Only the severe cases are followed by a slightly branny desquamation. Diagnosis and Differential Diagnosis.—The disease may be confused with measles, scarlet fever, and the indigestion and drug erythemata. The mildness of the symptoms is a strong point in favor of German measles. Exceptionally, a severe case may be difficult to differentiate from true measles. In such an instance the absence of eruption on the buccal mucous membrane (Koplik spots) is a valuable aid. Further, the typical postcervical lymph-gland enlargement does not occur in measles. Scarlet Fever.—The characteristic angina, which is a fairly constant symptom in scarlet fever, is never present in German measles. There is no post-cervical gland enlargement early in scarlet fever; and while the rash of German measles may resemble that of scarlet fever, the former exanthem is coarser in appearance, the punctate dots are larger, and the rash presents a blotched appearance, in contradistinction to the general diffuse intense blush of scarlet fever. In scarlet fever, furthermore, the desquamation is characteristic. In erythema due to drugs there is no manifestation of illness of any nature. A rash due to indigestion is very transient and is apt to be urticarial in type. Complications.—We have never known a complication to develop with this disease. Prognosis.—We have never known a fatal case. Treatment.—Rest in bed for about two days, confinement to the house for a slightly longer period, reduced diet, and the promotion of free bowel action are usually all that are needed. Recovery is ordinarily complete in six to eight days from the beginning of the attack. Isolation is not a necessity unless there are very young or delicate children in the family. Diphtheria has been known by its present name for less than a cen- tury, although the terms “ulcus Syracum” and “ulcus Egyptacum,” together with references to certain anginas with very peculiar expec- toration, indicate that the disease was prevalent as far back as the time of Hippocrates. As early as 100 B. C. Asclepiades, of Bithvnia, quoted by Galen and Aretseus, is said to have known diphtheria and practised laryngotomy. Aretseus gave the first important description of “angina gangrenosa,” and Galen, in the second century, described the mem- branous expectoration. Not, however, until the early part of the eighteenth century did DIPHTHERIA DIPHTHERIA 687 study of the disease become productive. In 1719 Wolfgang Wedel, of Jena, issued a document on the value of isolation. A little later an epi- demic near Boston, and in 1745 another in Paris, resulted in the des- cription of cutaneous diphtheria and of paralysis of the palate and eye muscles. Home accurately described the membranes in 1765 and in- vented the term “croup,” to differentiate the condition under discussion from the “angina maligna” or “gangrenosa” of ancient writers. Not until the publication in 1826 of Bretonneau’s famous treatise on the epidemics at Tours was the pathology of the disease accurately defined. Bretonneau combined all the inflammations previously called angina gangrenosa, ulcers, and croup under the term “diphtheria” {AiyO-rpm, a membrane) and asserted his belief that direct inoculation and contact were the only modes of transmission. The later history of diphtheria contains its two most important epochs: the discovery by Klebs of the bacillus, in 1883, with its isolation and cultivation by Loffler in 1884; and the introduction of antitoxin into general use as a result of long experimentation (by Behring, Roux, Martin, Chaillon, and Yersin) with the serum of actively immunized animals. Since the report of Roux in 1894 that in certain hospitals antitoxin had reduced the mortality from 58 per cent, to 20 per cent., the wider and more intelligent use of this specific has revolutionized the disease. Age.—Diphtheria is of rare occurrence before the first year, although no age is exempt. Our youngest patient was five months of age. A case in the practice of a colleague occurred at the sixth week. The most susceptible age is between the second and tenth year. Predisposition.—Vigor of constitution appears to exert no influence on susceptibility to the disease. The strong and the delicate are alike subject to the infection. Zingher’s investigations with the Schick test, however, have demonstrated a larger proportion of susceptible children among those living in the less populous, better communities than in dense tenement districts where the children have had mild undiagnosed attacks. Diseased Throats.—The presence of diseased tonsils and adenoids appears to be a decided predisposing factor. Throats so involved possess a poor resistance to the infection. It is apparent that a normal throat is a valuable prophylactic agent, which means that children whose diseased tonsils and adenoids have been removed have the best chance to escape after an exposure. Transmission.—Diphtheria is both transmissible directly through contact, and indirectly through an intermediary. Transmission from the diseased to the well is usually through personal association. That the disease may also be transmitted through an intermediary person, book, or article of clothing, is not to be questioned. Nevertheless, sec- ondary sources of exposure are undoubtedly much less a factor than is generally accepted. Diphtheria may be so mild in an individual that its presence is not suspected, and to such mild ambulatory cases is due in many instances the spread of the disease. Diphtheria Carriers.—In many instances the presence of the diph- theria bacillus is demonstrable in the nasal secretions of healthy children. In a series of observations upon public school children in Baltimore Styles found diphtheria bacillus in 5 per cent, of cases. 688 THE PRACTICE OF PEDIATRICS Bacteriology.—The morphology of the Klebs-Loffler bacillus varies greatly, but it has a characteristic irregularity of staining and regularity of grouping which are aids to diagnosis. Its demonstration in smears or cultures from the site of the lesion is a necessity for the diagnosis of diphtheria. With the weakly alkaline methylene-blue stain recom- mended by Loftier the bacilli appear striped, unevenly beaded, granular, or clubbed. They are arranged in groups of four or six elements, lying parallel or at sharp angles. The most frequent localization of Bacillus diphtherise in the human body is on the mucosa of the throat, larynx, and nose. The infection may travel down into the lung, causing bronchopneumonia, or into the stomach, causing pseudomembranous gastritis. The bacilli have been found in pus from the middle ear, and the pseudomembranous lesions on the skin and vulva. Exceptionally the conjunctiva is infected. As a rule, Bacillus diphtherise remains localized at the site of the lesion it has produced, and only in very rare instances does it invade the blood— probably as a terminal condition. The toxin formed by the bacillus is responsible for the general symptoms. The bacillus may persist in the throat for weeks after an attack of diphtheria, however mild such an attack may have been. These bacil- lus carriers become a menace to other persons, since a mild attack of diphtheria in one individual may yet produce a severe case in another person. The Schick Test and Toxin-antitoxin Immunization.—In the Schick test a minute quantity of diphtheria toxin is introduced intradermally. The effects indicated by a local reaction determine the susceptibility of the individual to diphtheria. Toxin-antitoxin injections are employed to confer active immunity upon those who are susceptible. Susceptibility to Diphtheria.—As mentioned elsewhere very young infants have been looked upon as possessing a natural immunity to diph- theria. Among several hundred cases but two were seen under six months of age. Interesting observations as to the susceptibility of children at vari- ous ages have been published by Schick, as follows: Age. Total. Schick’s. Positive Schick’s. Per cent, positive. Newborn 291 275 16 7 First year 42 24 18 43 2 to 5 years 150 55 95 63 5 to 15 years 264 133 131 50 Totals 747 487 260 34.9 It will be observed that in the newborn but 7 per cent, were susceptibh to diphtheria. Among 747 children under fifteen years but 34.9 pei cent, were susceptible to the disease. It has been proved that an attack of diphtheria not only causes nc immunity, but renders the individual more readily susceptible to future attacks. PLATE 111 a b d c Shows four typical positive Schick reactions of varying degrees of intensity forty-eight hours after test; (a) is a strongly positive reaction, with vesiculation of the surface layers of the epithelium, which is seen occasionally in individuals who have practically no antitoxin; (b) and (c) are positive reactions; (d) a mod- erately positiye reaction. a b c d Shows a fading positive Schick reaction one to four weeks after test in various stages of scaling and pigmentation; (a) shows redness, scaling and beginning pigmentation after one week; (b) and (c) pigmentation after two and three weeks; (d) faint pigmentation after four weeks. (Zingher, American Journal of Diseases of Children, April, 1916.) PLATE IV a b c Shows two pseudoreactions forty-eight hours after test, and a combined reaction; (a) mild; (b) marked; (c) a combined positive and pseudoreaction. (Zingher, American Journal of Diseases of Children, April, 1916.) DIPHTHERIA 689 It has also been demonstrated that susceptibility runs in families. When one child in a family is Schick-positive others are apt to be positive, and the same holds with negative reactions. Technic.—Schick published an elaborate technic which was not prac- ticable for ordinary purposes. Park and Zingher have simplified the technic and this, with slight modification, has been employed on a large scale in the testing of many thousands of children in the New York schools. The toxin is supplied in capillary tubes. The contents of a tube is mixed with 10 c.c. of sterile salt solution and 0.2 c.c. of the solution is injected intradermally with a fine hypodermic needle. There may be three results following intracutaneous injection of diphtheria toxin: Negative.—Where no local reaction at all occurs about the injection point. Pseudopositive (Plate IV) (meaning not positive at all).—Where a red area, probably anaphylactic in character, appears within the first twelve to twenty-four hours, but disappears in thirty-six to seventy- two, with little or no pigmentation. Positive (Plate III).—Where in thirty-six to forty-eight hours a red, generally clearly outlined area about \ to 2 cm. appears about the in- jection point, which lasts, becoming a brick red in two, three, or four days, the skin then wrinkling and scaling, after which the discoloration grad- ually disappears, taking three to six weeks to entirely disappear. Negative signifies immunity. There is sufficient antitoxin in the sys- tem to neutralize the poison introduced. Pseudopositive also signifies immunity. Positive signifies no immunity. There is not enough antitoxin in the system to neutralize the poison introduced. The individual reacting pos- itive is susceptible to diphtheria. A combined reaction (Plate IV), rep- resenting the positive and pseudo-reaction in the same individual and showing evidences of a true reaction after the pseudo-element has dis- appeared, indicates absence of immunity. According to Zingher1 three prerequisites are necessary for the test: (a) a reliable toxin, (b) a proper technic, and (c) a correct interpretation of the reaction. Care in getting and keeping the toxin will answer the first. A good syringe (preferably a 1 cc.), and a fine, sharp but short-beveled platinum-iridium needle are needed for the second. The ability to carry out the test properly is easily acquired. One point that may serve in guiding one in the injection of the diluted toxin might be emphasized. If the needle has been inserted in the proper layer of the epidermis, then the oval open- ing of the needle will be visible through the superficial layers of cells. A definite wheal- like elevation, with the distinct markings of the openings of sweat-glands, shows that the injection has been made properly, and that the fluid is confined to a small area, of the epidermis. Here it will exert its irritant action if the individual tested is not im- mune to diphtheria. ' Summary and Conclusions.—The following statements quoted from Park2 present concisely the results of twenty-five years’ investigation of the immunizing effect of toxin-antitoxin injections and the value of the Schick test: “Three injections, 1 c.c. each, of a suitable toxin-antitoxin mixture spaced one or two weeks apart, will cause about 85 per cent, of susceptible children or older persons 1 Amer. Jour. Dis. of Child., 11, 269, April, 1916. 2 Jour. Amer. Med. Assoc., vol. 79, No. 19, pp. 1589, 1590. 690 THE PRACTICE OF PEDIATRICS to develop sufficient antitoxin to give the negative Schick reaction and produce marked, if not absolute, protection against diphtheria. “The development of the immunity is slow. An amount of antitoxin sufficient to prevent the positive Schick reaction develops in the different children in from one to six months after the receiving of the injections. Antitoxin, as heretofore, must continue to be used to produce immediate immunity. “The duration of the immunity in at least 90 per cent, of the children is for more than six years and probably for the remainder of life. There seems to be no difference in this respect between these and those who develop antitoxin naturally. “Toxin-antitoxin injections should not be given within two weeks after an injec- tion of antitoxin; otherwise the toxin is slightly overneutralized and the resulting development of antitoxin is lessened. “Mixtures made from old toxin and antitoxin are fairly stable and may be used for a period of one year. Even such preparations are at their best when first sent out, as the mixtures slowly tend to become at first neutralized and then slightly antitoxic. This change gradually lessens the immunizing power of the toxin. The toxin-antitoxin should be kept cool and in a dark place; it is best to use the mixtures within three months after their final preparation. “A toxin-antitoxin mixture of stabilized materials which is safe when it leaves the laboratory cannot become more toxic on being kept. No serious effects have ever resulted from the injections given to the tens of thousands of the New York chil- dren since we began our work, seven years ago. “The Schick test is an extremely reliable means of separating those individuals who have antitoxic immunity from those that have none. Although a simple test, it must be carried out with extreme care. The toxin must be retained intracutaneously, and the toxin must be neither 25 per cent, more nor less than the desired amount. It is extremely important to choose glass of suitable chemical composition for the con- tainers in which the toxin is to be placed, as otherwise rapid deterioration may take place. “The preliminary Schick test is usually omitted in children under three years of age. This is for two reasons: 1, Two-thirds of these children require the toxin-anti- toxin injections anyway. 2, We are not certain whether those that do give the negative reaction are immune because of an unusual persistence of the antitoxin given them by their mothers, or because of the active development of antitoxin in their own bodies. After this age the test is desirable, but it is often omitted. “Thus, in practical school work, the first Schick test is frequently omitted in chil- dren up to the age of six because it is easier to inject the children at once rather than to delay for the test. At this age the percentage of children requiring immunization is still high, and the annoyance from the injections is slight. The omission of the preliminary Schick test facilitates the introduction of the immunizing injections in the schools. Above the age of six years the preliminary Schick test should be made when- ever practicable. “No child should be pronounced immune from diphtheria because of having re- ceived three immunizing injections of toxin-antitoxin. A negative Schick test is abso- lutely necessary before one can properly make such a statement or issue a certificate. “The use of the control protein test made with the heated toxin is advisable at all ages when a careful separation of the pseudonegative reaction from the combined positive reaction is important. As with the Schick test, it is frequently omitted be- cause of local conditions. The older the child, the more likely it is to be immune and to give a confusing protein reaction. In children under five years of age the protein reaction seldom confuses the picture if the Schick tests are read as late as on the fourth day; between five and seven years the control does not help greatly in more than 5 per cent. In older children and adults not only does the control protein test help us to decide more correctly in about 10 per cent, of doubtful reactions; but when it is marked it also indicates with some probability those persons who are likely to have the marked local and constitutional reactions from the toxin-antitixin injections. “The toxin-antitoxin injections are inadvisable before the age of six months. During this time most of the infants retain the antitoxin received from their mothers. Up to the age of three months immunizing injections are usually ineffective, as the infant tissues do not respond sufficiently during this period to the toxin-antitoxin to produce antitoxin. Under usual conditions it is probably safe to wait until the infant is nine months old and then to give the injections at the first suitable occasion. During the first three years there is almost no annoyance from the injections. As the child grows older the danger from diphtheria gradually lessens, and the percentage of those de- veloping annoying local and constitutional reactions slowly increases. “The immunization of school children in acting to prevent their contracting diph- theria also lessens the exposure to infection of the younger children of preschool age in their families. “There appears to be no difference in the degree of immunity between those indi- DIPHTHERIA 691 viduals who have developed antitoxin from natural causes and those who did so because of the stimulus of the toxin-antitoxin injections. “Institutions in which the children have been given the immunizing injections have been remarkably free from diphtheria. “The school children who have been injected have had one-fourth as many cases as the untreated children, and these cases have been of less severity.” \ Pathology.—Following an invasion of the mucous membrane by the specific bacillus, a pseudomembrane is thrown out which is firmly ad- herent to the underlying mucosa. The false membrane may be thin and grayish in color, or thick and yellow. It is the result of exudation into the mucosa, ulceration, and necrosis. The mass thus formed is composed chiefly of fibrin, in the meshes of which are entangled poly- nuclear leukocytes, desquamated epithelium, and bacteria. The fibrin may be deposited in fairly definite layers. Ulceration and small hem- orrhages occur in the subjacent tissue, which is very edematous, and detachment of the membrane may leave a raw, bleeding surface. When the separation occurs naturally, the loosening process is one of autolysis, and large defects in the tissue are healed by granulation. New epithelium is generally flat, and cicatricial contractures are common. The Klebs- Loffler bacilli present in the exudate during the acute stage are usually associated with other organisms, such as streptococci and staphylococci, which determine to some degree the appearance of the membrane. Any of the mucous surfaces may be involved. The process may involve the nasal cavities, the lips, the mouth, the conjunctiva, tonsils, pharynx, trachea and bronchi, and rarely the esophagus. The involvement of the trachea, bronchi, and esophagus in a case observed by the writer was proved at autopsy. The rectum and vagina have also been the seat of the disease. Incubation.—The period of incubation is variable. It may be but a day or two, or it may be a week. According to estimate, 1 per cent, of school children carry the bacilli in their throats in a viable form, and yet by no means 1 per cent, of the children develop the disease. Symptoms.—One of the most important features of diphtheria, in the great majority of cases, is the slow and gradual onset. At first the child may complain of being tired or sleepy and of loss of appetite. Symp- toms referable to the throat may appear, but pain is not necessarily present. The breath becomes offensive. The physician is sent for on the first, second, third, or some later day, depending upon the intelligence of the parents or nurse or upon their confidence in themselves to care for what, at the time, appears to be a simple condition. The child, not willing to go to bed, is looked upon by the uneducated eye as being not at all sick. By the time the case is seen by a physician much valuable time may have been lost. The earlier antitoxin is used, the more certain the recovery. A delay of forty-eight or even twenty-four hours may mean a fatal issue. Not every case has so gradual an onset. Illustrative Cases.—In the pre-antitoxin period, late in the eighties, an asylum patient died eighteen hours after the appearance of the first symptom. In March, 1910, a father came leading by the hand two children, aged three and six years. Both had been ill about three days with fever and some difficulty in swallow- ing. They were supposed to have tonsillitis and had not seemed at all ill to the father. 692 THE PRACTICE OF PEDIATRICS A glance showed that they were very ill. On further examination the throats of both were found filled with membrane. They were at once sent to the Willard Parker Hos- pital and given large doses of antitoxin. One child died in twelve hours and the other in twenty-eight hours. Localization of the Membrane.—The usual site of the membrane is on the tonsils and the pillars. The pharynx is more rarely involved, and when involved, has usually become affected through extension of the primary lesion. Temperature.—The temperature, unfortunately, is rarely high early in the case. It seldom rises above 102° F. The lower temperature and gradual onset are accountable for many deaths, the physician being called late in the disease. The Lymph-glands.—Swelling of the lymphatic glands at the angle of the jaw is an early symptom in about 30 per cent, of the cases. Diagnosis.—Visible membrane should always be looked upon as diphtheric, and treated accordingly with antitoxin. Any physician who has looked into thousands of throats, will feel sure that the man is yet to be born who can safely affirm after inspection alone, that a given membrane is not due to the Klebs-Loffler bacillus. There is no invariable manifestation, no reliable characteristic of pseudomembrane due to the Klebs-Loffler bacillus. Antitoxin should be given in any suspected case, and then a culture should be taken. Following out this practice we often give antitoxin to children who are later found not to have diphtheria, as proved by repeated cultures. Never have we regretted this practice. Differential Diagnosis.—Both the streptococcus and staphylococcus may produce a membrane identical in appearance with that produced by the Klebs-Loffler bacillus, and the disease may be differentiated only through cultural examination. Tonsillitis.—In tonsillitis the temperature is high—103° to 105° F. The child is usually much prostrated, and appears very ill. The phys- ician accordingly is called much earlier to the patient ill with tonsillitis than to the one ill with diphtheria. In tonsillitis the tonsils are more apt to be swollen and enlarged, the exudation appearing in the form of white dots which stud the surface. Care must be exercised, however, in cases which appear to be those of frank tonsillitis. The points of exudation may coalesce and in a day or two may produce a distinct membrane firmly organized. The only safe practice is to make a culture in every case showing visible exudation, whether this is on the tonsils or elsewhere. Illustrative Case.—A mother developed fever and sore throat. The left tonsil was clear. On the right tonsil there were three or four yellowish-white points of exuda- tion. The condition was pronounced tonsillitis by the physician in attendance, and she was not visited further. In four days the doctor was again sent for, and found she had diphtheria with extensive membrane on both tonsils. The mother passed through a desperate illness and recovered completely in six months. In addition to a myo- carditis she developed diphtheric paralysis of both lower extremities. Two of her three boys developed the disease and recovered without inconvenience following the early and free use of antitoxin. Many other instances of the atypical onset of diphtheria might be re- cited reinforcing the view that one should never look lightly upon a throat showing exudation on its mucous membrane. DIPHTHERIA 693 Prognosis—A favorable prognosis in a given case depends largely upon two factors: An early diagnosis and a knowledge of the use of antitoxin. The natural resistance of the patient is most important, and particularly important is the condition of the throat—whether normal and resistant, or filled with diseased tissue, supplying a favorable culture field for the invading bacilli. Complications. The complications, are bronchopneumonia, nephritis, endocarditis, otitis, adenitis, and diphtheric paralysis. Treatment.—Owing to our knowledge of the etiology of diphtheria, and as a result of the advent of the specific remedy, antitoxin, the dis- ease has lost much of its former terror. Diphtheria is still, however, an important contributor to the death-rate of all large cities. This is due, fust, to parents who fail to appreciate the possible dangers that may aiise from a sore throat and who neglect to call a physician early in the illness, and, second, to physicians who do not believe in diph- theria antitoxin, who timidly use it in small doses late in the disease, or who wait for positive clinical signs or a report of a culture before using the remedy. Equally as necessary as the realization of the value of antitoxin is the knowledge of how and when to use it and when to re- peat its use. In many cases, at the beginning of the disease, when the tonsils alone are involved, it is impossible, without the aid of the labora- tory* to differentiate diphtheria from tonsillitis. C'ase after case was witnessed in the pre-antitoxin period, in which two or three days were required to make a positive clinical diagnosis. In towns in which a bac- teriologic examination is possible it is in some instances safe to wait for a report from such an examination. When one is in doubt, a safer rule to follow in those cases in which there is pseudomembrane on the tonsils is to give antitoxin at once. If the case proves to be one of simple tonsillitis, no harm will follow greater than the inconvenience ordinarily attendant upon the administration of horse-serum. Illustrative Case. During the winter of 1906-07 a girl six years old developed a gray, membranous patch on the left tonsil, of the size of the thumb-nail. There was a temperature of 101 1. 1 he child complained of feeling tired, seemed generally wretched, and had considerable difficulty in swallowing. Three thousand units of antitoxin were immediately given and a culture from the throat was sent to a private laboratory. Next morning the report arrived stating that the Klebs-Loffler bacillus was absent. At this time the membrane had extended and now covered the right tonsil. The 3000 units of antitoxin were repeated, and a second culture was sent to another private laboratory. Again the report was negative for the Klebs-Loffler bacillus, but the culture showed a pure growth of the streptococcus. The following morning the throat began to clear, and in two days was normal. Clinically this case was one of diphtheria. There was no scarlatina, but there was some swelling of the glands at the angle of the jaw. Aside from the improvement, the child showed no symptoms whatever to indicate that antitoxin had been given. At the present time a much larger initial dose of antitoxin would be given. Antitoxin Dosage.—W hen there is membrane on the uvula, the pillars of the fauces, the posterior pharyngeal wall, or in the nose, we should never await the report of a culture, but give a full dose of antitoxin at once. Ten thousand units should be given at the first injection. This should be repeated eight to twelve hours later if there is an extension of the membrane or if there is no change in its appearance. If the throat shows a tendency toward improvement, if there is a curling up and loosen- 694 THE PRACTICE OF PEDIATRICS ing of the edges of the membrane, or if it has taken on the granular ap- pearance peculiar to diphtheric membrane after the use of antitoxin, we may safely wait twelve hours longer—twenty-four hours in all— before deciding whether a repetition of the original dose or the admin- istration of a smaller one is required. If the case is seen on the third day or after, 10,000 units should be the initial dose and may be repeated as suggested above. In the nasal cases a diminution in discharge, a lessening of the breath fetor, a reduction in the glandular swelling, and a fall in the temperature—all are indications of improvement, but the physician should not rest unless the constitutional improvement and the clearing-up process are rapid and complete. W hen the case shows no sign of improvement, more antitoxin should be given. Intravenous, or at least intramuscular, injections are advisable for urgent cases because of the more direct absorption thus secured. A child ill with diphtheria must be looked upon as poisoned. Anti- toxin is the antidote, and every case must receive enough of the antidote to neutralize the poison. Means of Injection.—There are several antitoxin syringes on the market, any one of which may be used if it will admit of repeated boil- ing, for in every instance the syringe should be boiled before using. The “Record” antitoxin syringe satisfactorily fulfils these requirements. Some of the regular producers of antitoxin furnish it in a container with an appliance for subcutaneous injection. The advantages possessed by this combination are its convenience and its safety, for as the instru- ment has to be used but once, the danger of infection by means of a syringe which is used repeatedly is thus avoided. Site of Injection.—The skin over the abdomen between the umbilicus and the anterior spine of the ilium is doubtless the most convenient site for the injection. The skin is very loosely attached at this point and the serum passes freely under it, requiring very little force and pro- ducing no laceration of the tissues or soreness of the parts sufficient to interfere with the child’s customary position in bed. If the buttocks, favorite sites for the injection, are selected, the needle should be inserted well upon one side, so as not to interfere with the resting posture of the child. Before injection, the skin should be thoroughly scrubbed with green soap and washed with alcohol. Upon the withdrawal of the needle the skin should again be washed with alcohol, and a piece of zinc oxid plaster, 1 inch square, applied over the site of the injection. Under these pre- cautions regarding cleanliness there has never been, in our experience, a suggestion of a local infection. Late Injection.—Antitoxin should always be given in diphtheria, no matter how late in the disease the case may first be seen. In one case first seen by the senior author on the sixth day, 11,000 units were given. The child recovered. In a similar case one would now give 20,000 units. In another case of laryngeal diphtheria in a boy five years of age who was first seen on the fifth day 10,000 units were given, with prompt recovery. In a similar case 20,000 units as the initial dose would now be given and repeated if necessary. Even when the antitoxin has been given as late as the eighth day, recovery apparently due entirely to the serum has DIPHTHEKIA 695 been witnessed. In order to be signally effective, however, the serum should be given not later than the third day. The later it is given, the greater the amount required, and the greater the need of repeating the injection. Immunization and Quarantine.—When a member of a family becomes ill with diphtheria, the suggestions for quarantine (p. 707) should be carefully followed. In every case of diphtheria other children of the family should be immunized directly with antitoxin. Less than 1000 units should never be given for this purpose, regardless of the age of the child. Cultures should be taken from the throats of children and adults alike. If the Klebs-Loffler bacillus is found, the carrier must be isolated and treated as diphtheric so far as quarantine is concerned. Two children were observed who developed the disease after immunizing doses of antitoxin. A child nine months of age was given 3000 units and developed diphtheria four days afterward. This patient recovered after a second injection of 3000 units. A boy four years of age was given 1000 units for immunization. He developed diphtheria in thirty-six hours, which was controlled by the injection of 3000 units. The throat was clear in forty-eight hours after the second injection. Antitoxin Idiosyncrasy.—In 20 per cent, of the writer’s cases urticaria followed the use of antitoxin. The earliest appearance of the eruption was on the fifth day following the injection; its latest appearance, on the twenty-first day. The urticaria apparently differs in no respect from that due to other causes, and the treatment should be the same. Among local applications, a 1 per cent, solution of carbolic acid or a lead and opium wash relieves the itching better than do other measures. For internal administration salicylate of soda answers better than any other form of medication. To a child five years old 3 grains well diluted may be given every two hours until five doses have been taken, and this treatment may be repeated every day until the rash disappears. The hypodermic administration of 3 minims of 1:1000 adrenalin solu- tion will produce immediate subsidence of the urticaria and afford temporary relief. Exceptionally in horse-serum-sensitive subjects severe serum sickness with joint manifestations follows the use of antitoxin. In view of the oc- casional occurrence of sudden severe anaphylaxis following antitoxin injection an initial dose of a minute amount subcutaneously should regularly precede the therapeutic dose of antitoxin whenever the patient is not known to be free from horse-serum sensitivity. Remedial Measures Other Than Antitoxin.—Of the many remedies which have been advocated and used from time to time in the treat- ment of diphtheria, practically none remains in use at the present time. During the pre-antitoxin period the writer had abundant opportunity in 103 cases at the New York Infant Asylum, to test the value of drugs, inhalations, vaporizing treatment, local applications, gargles, and sprays. In an article relating to this epidemic of diphtheria which he wrote sev- eral years ago is the following statement: “The death-rate in the insti- tution from diphtheria was large-—about 60 per cent, mortality. In so far as the methods of treatment were concerned, all were equally valueless. The mild and some moderately severe cases recovered under good general management. The severe cases died regardless of treat- 696 THE PRACTICE OF PEDIATRICS ment.” In other words, there, was no method or scheme of treatment used at that time that was of any signal value. Happily, at the present time, all the old methods are forgotten. They are not needed. Anti- toxin is a specific. The use of sprays and gargles and applications is of value as a means of cleanliness only. For this purpose the throat irri- gation (p. 321) answers better than any other means. Forcible irrigation of the nose should not be employed. In such cases the danger of forcing infected material into the eustachian tube, with resulting secondary otitis, is real. To small children, if the breathing is interfered with be- cause of membrane or tenacious secretions in the nose, a few drops of liquid petrolatum instilled every hour will give as much relief as can be furnished by any other local measure. Sick-room Regime.—In the management of diphtheria the same sick- room regime should be enforced as in other serious diseases. The tem- perature of the room should never be above 70° F., and at all seasons of the year there should always be a free communication with the outer air by means of an open window. The child should wear the customary night-clothes, and the bed-clothes should be of the same weight as those used in health. Nourishment.—The nutrition of the patient is most important. As a rule, food is poorly taken because of the pain caused by swallowing. Inasmuch as but a few ounces may be taken at one time, the nourish- ment may well be given in as concentrated a form as possible. Milk should be given as the chief article of diet, with the addition of lime- water or bicarbonate of soda. If the taste of milk is disagreeable it may be mixed with equal parts of a thick gruel and well salted. Animal broths contain so little nutriment that their use is ill advised. The milk, plain or diluted, will often best be taken if given cold or cool, even to children under one year of age. Fluid will usually also be taken from a spoon or cup better than from a bottle, because of the discomfort produced by drawing on the nipple. When sufficient nourishment is not swal- lowed, gavage (p. 853) or rectal alimentation assists temporarily in main- taining nutrition. The Temperature.—This is rarely high enough to require the use of any means for its reduction. In case of high fever the sponge-bath or cool pack (p. 841) will answer the requirements. Heart Stimulants.—When the heart action becomes weak, irregular, or intermittent, stimulation will be necessary. For this purpose three drugs are of signal value—strychnin, digitalis, and alcohol. Laryngeal diphtheria may develop coincidently with a tonsillar or faucial diphtheria. The laryngeal inflammation may develop sec- ondarily after a day or two of illness, or it may be the first manifestation of the infection. When a child ill with faucial or tonsillar diphtheria de- velops a hoarse or croupy voice, with or without impeded respiration, almost invariably the larynx has become involved. Differential Diagnosis.—When, in the event of a hoarse, croupy voice with obstruction as the manifestation of illness, no membrane is visible, it is by no means easy to determine whether the case is one of membran- ous laryngitis or acute catarrhal laryngitis. The following suggestions have aided not a little in arriving at a right conclusion: DIPHTHERIA 697 Diphtheric membranous croup. Gradual onset. Obstruction persistent, with gradually in- creasing severity. Obstruction both to inspiration and ex- piration. Little or no response to emetics or in halations. No response to sedatives. Catarrhal croujp. Obstruction intermittent. Sudden onset. Obstruction to inspiration, but little to expiration. Response to emetics and inhalations and to sedatives. Contrary to the usual rule, the onset of catarrhal laryngitis may be gradual, while that of diphtheria may be sudden. In the consideration of a great many cases, however, the points of differentiation are of suffi- cient value to warrant the attention which has been given them. A particularly valuable sign of diphtheric involvement is the obstruction to expiration as well as inspiration. In catarrhal croup there is obstruc- tion to inspiration only. Treatment.—A safe rule to follow, in view of the urgent demand for early injections of antitoxin, is the same as in other forms of diphtheria, i. e., when in doubt, inject 20,000 units. From the gradual cessation of the laryngeal symptoms it is fairly safe to assume that the child is doing well, although the breathing may not be entirely free for forty- eight or seventy-two hours after the first injection. In cases which re- quire intubation 20,000 units should be given for the first injection and repeated the following day. According to our observation, severe laryn- geal cases require from 20,000 to 40,000 units, even when antitoxin is used early, by which we understand on the second or third day of the disease. The earlier the injection, as has been stated, the less frequent will be the necessity for its repetition. Nasal Diphtheria.—There are two distinct types of nasal diphtheria —the acute and the chronic. The acute cases resemble in all respects those of diphtheria as it occurs in the throat or larynx with the accompanying clinical manifestations of illness and prostration. There may be membrane elsewhere, and in many of the cases involving the throat and larynx the nares are also involved. At autopsies, before the advent of antitoxin, the nasal passages were often found plugged throughout their entire extent, the membrane being continuous from the anterior nares to beyond the first bronchial bifurcation. In what may be looked upon as the strictly nasal cases the mucous membrane of one or both nasal passages only is involved. Symptomatology.—A symptom pointing strongly to a Klebs-Lofffer infection of the mucous membrane of the nasal passages is a persistent excoriating mucous discharge, with or without a tinge of blood. The fever, prostration, and other evidence of the infection may be as severe as when the membrane is elsewhere located. Diagnosis.—The diagnosis is made by the appearance of the per- sistent excoriating discharge, by the discovery of false membrane in the nasal cavities, and by the finding of the Klebs-Lofffer bacillus in the nasal discharge. Exceptionally a foreign body in the nares may give rise to a similar persistent discharge without the presence of the diphtheria organism. 698 THE PRACTICE OF PEDIATRICS Treatment.—The treatment is with antitoxin, as suggested for the tonsillar and faucial cases. Persistent Nasal Infection with the Klebs-Loffier Bacillus.—Per- sistent nasal infection of a mild type is of much more frequent occur- rence than is generally known. These cases are sometimes alluded to by writers under the term “chronic nasal diphtheria.” Symptoms.—The child has a persistent sanious discharge from one or both nostrils, but shows no sign of illness other than that occasioned by the persistent rhinitis. Since there are no systemic effects, these are not cases of diphtheria in the accepted sense of the term. Ulcerations are occasionally produced, and there may be destruction of membrane, cartilage, and bone. Illustrative Cases.—Case 1.—A girl of eight years of age had a nasal discharge associated with considerable obstruction. The child had been ill for about one week, and had been treated for grip by home remedies. There had been slight fever and little or no prostration, but a serous nasal discharge which was at times bloody. There had been one or two severe nasal hemorrhages. An examination of the nasal cavities disclosed that both were filled with membrane, pus, and blood. Nasal diphtheria was at once suspected, and a culture was made wrhich was negative. During the following three days six cultures in all were made and examined by three different bacteriologists in three laboratories, and all reports were negative for the Klebs-Loffier bacillus. The membrane was removed on two occasions, and there were three fairly severe nasal hemorrhages while we were trying to determine the nature of the infection. Various local measures were employed without in any way influencing the process. After the case had been observed one week, during which time the child remained free from con- stitutional disturbance of any nature, 5000 units of antitoxin were given. In twenty- four hours the nose was clear and only a considerable erosion on the septum remained, which promised to give trouble because of its depth and tendency to bleed. This area was cauterized and healed promptly, and the child was then well. Interesting is this case in view of the cultural absence of the Ivlebs-Loffler bacillus, and the prompt response to antitoxin, which indicated beyond doubt that the case was one of diphtheria. Case 2.—A strong, robust boy, twelve years old, from a New York suburb, came for examination solely on account of inability to breathe through his nose and a night cough which was quite severe. Examination showed the nose to be filled with crusts, pus, and dried blood. Upon removing the obstruction a bleeding surface was left on both sides, and a perforation of the septum, the size of a dime, was found posteriorly. A culture was taken and showed a pure growth of the Klebs-Loffier bacillus. Five thousand units of antitoxin were given. The condition immediately improved. Within four days the nose was free from the Klebs-Loffier bacillus. This condition had existed for at least a year. Case 3.—A girl four years of age became ill with fever, which persisted for thirty- six hours, when the attending physician noticed a swelling and edematous condition of the soft palate. On seeing the case forty-eight hours after the onset the writer found the swelling and edema still present, with considerable post-nasal discharge. At no time was membrane visible. A culture was taken which proved negative. Five thou- sand units of antitoxin were given, and the child made a prompt recovery in about forty-eight hours. While there is no direct proof that the child had diphtheria, the prompt recovery after antitoxin suggests this condition. The absence of cultural proof, in view of experience in the first case recounted, does not signify that the infection did not exist. Case 4.—A mother presented for treatment 2 children aged two and four years, both of whom had had a chronic cold in the head for six weeks. There wras a persistent nasal discharge from both nostrils in each patient, serous in character, requiring several handkerchiefs daily. The children were generally well and happy. A culture showed Klebs-Loffier bacilli in both. Five thousand units of antitoxin given to each child cured the condition. Much remains to be learned regarding the Klebs-Loffier bacillus and its action upon the individual. The effects of this organism may be entirely local. Every year in hospital work we see many of these DIPHTHERIA 699 cases. In private they are less frequently encountered. On the other hand, what is apparently the same organism, with the same morphologic characteristics, may produce not only local effects but the most pro- found systemic toxemia and death. In the cases with local manifestations, are we dealing with the Klebs- Loffler bacillus in an attenuated form, or is the infection of a different nature and due to another organism of the same family? Although it would seem readily possible for the patients showing only local manifes- tations to transmit the disease to others with resulting systemic effects, the writer has never known of such an occurrence. Treatment.—In these cases usually one dose of 5000 units of anti- toxin is sufficient. If the process is not controlled, this dose should be repeated. Intubation.—To the genius of the late Dr. Joseph O’Dwyer, of New York, is due the perfecting of this operation. It will forever stand as a monument to the inestimable service which he rendered to mankind. The O’Dwyer intubation set furnishes us with the necessary instruments for the operation. Various modifications of the tubes, the introductor and the retractor have been attempted from time to time by others, but the original perfected design of O’Dwyer has yet to be improved upon. Intubation of the larynx may be required in case of a retropharyn- geal abscess situated low on the posterior pharyngeal wall, edema of the larynx, or acute laryngitis. The greatest usefulness of the operation, however—that for which it was designed—is to relieve the stenosis of laryngeal diphtheria. Before attempting to introduce a tube into the larynx of the living subject the physician should familiarize himself with the operation on the cadaver. In no other way can the procedure safely be learned. Attempts at intubations by the unskilled on the liv- ing subject can result only in laceration and other gross injuries to the parts. Indications for Intubation in Diphtheria.—When to intubate is a ques- tion puzzling alike to students and to many physicians. It has been variously answered, and many attempts have been made to formulate a series of clinical manifestations the presence of which would render the operation necessary. Thus, it has been said to be indicated when there is a pronounced recession of the suprasternal and infrasternal regions, and when, as a result the stenosis, air enters the bases of the lungs but feebly or not at all. It may safely be said that intubation is rarely done too early, but it is very apt to be done too late—not too late in a great major- ity of instances to be of some service to the patient, but too late to be of the greatest possible service. The best rule regarding intubation in laryngeal diphtheria is to intubate when one sees that the child is wasting vitality in his efforts to carry on respiration. Intubation should not be postponed until he becomes exhausted in the struggle for air. Diph- theria is a disease in which every possible strength-unit must be pre- served. Energy wasted in supplying air is an unnecessary waste. Operation.—For the operation of intubation the patient should be wrapped from his shoulders to his feet in a sheet securely pinned from top to bottom. The older and stronger the child, the more this is neces- sary. The patient is held on the lap of the nurse, who passes her right 700 THE PRACTICE OF PEDIATRICS hand around the child’s body. The child’s body rests on the nurse’s right shoulder, firmly held in position by her left hand. Tf the child be large and strong, a third person may be required to hold the head, with the patient recumbent. After the gag is in position, the operator, holding the introductor in his right hand, locates the glottis with the fore- finger of the left and using it as a guide directs the tip of the tube into the larynx. He must be certain that the tip is properly placed before exerting pressure to put the tube into position. This can readily be ap- preciated by one who has practised on the cadaver. When the tip of the tube positively is engaged in the glottis, gentle pressure will put it into final position. Force should never be used, even when the tube is started right, for the child may require a smaller tube than his age indi- cates. This is rather unusual, however, as are the cases which require larger tubes than the age calls for. When the tube is easily coughed up, it is essential to introduce the next larger size. With the tube in position, the obturator is quickly removed. One should never trust to pressure on the shank of the introductor to disengage the obturator, but keep the guiding index-finger of the left hand on the expanded head of the tube in order to insure its remaining in position during the extraction of the obturator. Results of Intubation.—After the operation the child who has pre- viously been struggling will take a deep inspiration and cough. One of the most welcome sounds to the operator is the sharp rattle produced by the passage of air through the mucus which has been forced into the tube. This tells him that the tube is in position and that speedy relief of the stenosis may be expected. The intubated child will usually cough vigorously for several minutes, and in so doing may bring up a quantity of mucus and shreds of membrane. One is often astonished at the large pieces of membrane and the quantity of thick mucus that can pass through the comparatively small lumen of the tube. In a few cases the presence of the tube in the larynx has caused such a persistent cough that a sedative was required to control it. Small doses of bromid of soda—4 grains every half-hour for two or three hours, for a child four years of age—usually answer the purpose. The thread, looped and knotted, attached to the tube, should be long enough to extend 4 or 5 inches beyond the lips. In case relief to the stenosis is not immediately perceptible after the operation, or if the breath- ing is made more difficult, one may be sure either that the tube is not in position or, if in position, that it is plugged with membrane, or that membrane may have become disengaged and is pushed downward ahead of the tube. A tube in the esophagus, where, in hospital service, it is often placed by interns, may exert sufficient pressure upon the posterior portion of the larynx effectually to impede respiration. Illustrative Case.—It became necessary to intubate a boy two years of age who was suffering from moderate stenosis due to diphtheria. The tube was easily intro- duced, but its introduction was followed by entire cessation of respiration. The tube was immediately extracted by means of the attached thread and was found to be plugged with membrane requiring considerable pressure with a wooden toothpick to dislodge it. The stenosis evidently was somewhat relieved as the result of dilating the parts and a removal of a portion of the membrane, but not sufficiently to insure permanent relief to the patient. The tube was again introduced, followed by a com- plete relief of the stenosis. SCARLET FEVER (SCARLATINA) 701 Displacement of the Membrane.—When membrane is dislodged and pushed ahead of the tube, it will usually be expelled by coughing after the extraction of the tube. Illustrative Case.—A case of this nature, following the withdrawal of the obturator, occurred in a child six years of age, whose breathing, before difficult, became impossible. The child struggled violently, became much excited, and with one hand free, knocked the gag from the mouth. Upon efforts to extract the tube the string broke, and while the gag was being introduced in order to use the extractor, the child’s struggles and attempts at coughing dislodged both the tube and a large amount of membrane, one piece of which, inclosing the tube, came out as a perfect cast of the larynx and upper trachea. The relief was immediate. Reintubation was not attempted, nor was it later necessary. The child had been given 5000 units of antitoxin twenty-four hours before, which helps to explain the dislodgment of the membrane. Removal of the Tube.—When the patient is progressing satisfactorily, the question arises: How soon may the tube be removed? Rarely should this be done before the fourth day after intubation. When the tube is taken out on the second or third day, for cleansing or other purposes, it must usually be replaced. Necessity for Intubation.—With the introduction of antitoxin, the necessity for intubation has become less frequent. The free use of anti- toxin—10,000 to 30,000 units as an initial dose—given with the first sign of obstruction, and repeated at eight-hour intervals until two, three, or more doses have been given, will render intubation a still rarer necessity. One does not feel safe in these cases until 15,000 or 20,000 units have been given. Fortunately, in laryngeal obstruction due to diphtheria the stenosis is usually of gradually increasing severity, so that by the early use of antitoxin many cases are relieved before the necessity for opera- tion arises. Suction in Laryngeal Diphtheria.—In view of the high mortality ranging from 25 to 40 per cent, in intubated hospital cases suction aided by direct laryngoscopy has recently been used at the Willard Parker Hospital by Gover and Hardman1 with signal success. This method promises to lessen the number of cases requiring intubation and trache- otomy, but should not be attempted by one unfamiliar with laryngoscopy, intubation, and tracheotomy. SCARLET FEVER (SCARLATINA) Scarlet fever has been clearly recognized for many centuries, although its early history is exceedingly obscure. The disease has always been most prevalent in civilized portions of the world, has shown remarkable differences in the severity of its separate outbreaks, and in almost all instances notably refrained from attacking a certain proportion of ex- posed individuals, in this respect contrasting sharply with measles, which exhibits no such selectiveness. Jurgensen reported an epidemic which in the years 1873 to 1875 ravaged the Faroe Islands, where for at least half a century the inhabi- tants had not been exposed to the disease and where the geographic conditions rendered observations on its course unusually easy. Here the discovery was made that, from a population comprising all ages and certainly not protected against scarlatina by a previous attack, only 1Arch. of Pediat., March, 1923, 702 THE PRACTICE OF PEDIATRICS 38.3 per cent, suffered from the epidemic, whereas a similar study of measles in the same locality showed that 99 per cent, of the population unprotected by previous infection were attacked. It was furthermore observed that the susceptibility to scarlet fever was about seven times greater in persons under twenty than in those over forty. The records of certain European epidemics exhibit a mortality as high as 30 per cent., contrasting with a rate as low as 3 per cent, for the same place at another period. In New York State scarlet fever easily ranks among the dozen most prominent causes of death, usually causing a comparative mortality of five, to four of measles and six of typhoid. Recent studies of the disease have been devoted extensively to a search for the specific cause, our ignorance regarding which has been in the past the most serious obstacle in the management of cases. A resume of the more important recent contributions dealing with the specific aspects of the disease has been presented by Ruth Crabtree1 and to this we have resorted for numerous facts here cited. Etiology.—The specific etiologic factor in scarlet fever was early recog- nized as present in the throat and in discharges from complicating otitis and other suppurative inflammations, and the constant association of the streptococcus with this disease led to the belief that this organism was the cause. Moser,2 as early as 1902, contended that the streptococcus found in patients was of a specific type. This belief, however, gave way to the view quite generally held that the streptococcus found in scarlet fever cases was merely a secondary invader. It was not until after the introduction of methods devised by Dochez and Avery3 based on biologic immunity reactions that it was established that the strains from throats of scarlet fever patients were specific. Attempts to produce the disease experimentally culminated late in 1923, with the inoculation of volunteers by the Dicks,4 and the production of a disease practically identical with scarlet fever in guinea-pigs by Dochez and Sherman.5 Transmission.—The infection is usually transmitted through asso- ciation of the diseased with the unprotected. Conveyance of the infection by an intermediary probably is of rare occurrence. Milk may be a means of conveyance. It has long been appreciated that scarlet fever is among the less contagious of the contagious diseases. Repeatedly when a case has been seen to develop in a hospital ward, there has been no occurrence of the disease in other children confined to bed and so kept from immediate contact with the scarlet fever patient. The most contagious period is probably during the first three or four days of the illness. The danger of transmission during the period of desquamation is much less than is generally believed. Although, until more concerning the nature of the infecting agent is known it is not wise to make definite statements respecting the period of communicability, observation of a great many cases in institutions and in private work leads to the belief that the desquamation seldom, if ever, transmits the 1 Archives of Pediatrics, xli, 6, June, 1924. 2 Jahrbuch f.

SCARLET FEVER (SCARLATINA) 703 disease. Even before the specific etiology of the infection was established many authors were inclined to place less emphasis upon the possible contagion from cutaneous scales and more upon the infective character of the nasal and aural discharges. Evidence is at hand showing that books, clothing, flowers, and food- stuffs are means of conveyance from the diseased to the unprotected. From personal observation, we have never known of a case having been contracted in any of these ways. A great many cases of scarlet fever are seen, however, which, ordinarily, would have passed undiagnosed if the patient had not been suspected because of known exposure. Cases are frequent in which a positive immediate diagnosis is quite impossible. Illustrative Case.—During the visitation of scarlet fever to a family, four children were attacked. Dr. S. Finley Bell had treated the two other members of the family at Englewood, a suburb of New York. A trained nurse caring for the children con- tracted the disease and died. Later, a girl six years old died with the disease. On a visit to one of the children who had been sent to New York Citv and later developed the disease, a member of the family called attention to the arms of the laundress, which were slightly reddened. It was Monday morning and she was washing. She had no temperature, a normal throat, no rash except upon the arms, and felt well and was annoyed that she should be disturbed in her work. The redness of the arms disappeared after the completion of the washing, and nothing further was discovered until two weeks later, when she was found to be desquamating profusely on the hands and feet and slightly over the body generally. She was sent to the Willard Parker Hospital, where she reouired two weeks to complete the desquamation. Here was a case in which a most careful search failed to reveal any conclusive evidence of scarlet fever, and yet the woman was proved to have had the disease at the time of examination. There is strong probability that many of the cases of obscure origin are contracted by exposure to such atypical cases, rather than through infected milk, books, articles of clothing, or intermediary human carriers. Susceptibility.—The most susceptible age is from the second to the twelfth year. Cases occurring in children under one year old are rare. The very young appear to possess a distinct immunity. Illustrative Case.—During an epidemic at the New York Infant Asylum at Mt. Vernon, N. Y., a colored boy was found to have the disease in a very active form. The institution was built on the cottage plan and this boy, 28 runabout children, and 4 nursing women orderlies with their 4 nurslings occupied the ward on a second floor in one of the two-story cottages. The institution, comprising 400 children and about 200 women, was crowded. To break up the ward would have meant that the exposed children, some of whom would probably develop scarlet fever, would be placed with unprotected and unexposed children. It was, therefore, decided to quarantine the ward with its inmates. Every child in this ward developed scarlet fever except the four nurslings, who at the time of the outbreak were under three months of age. Three of the women also escaped. The fourth woman developed the disease and had a moderately severe attack, during which time she nursed her infant, which remained well. It is of interest that so effective was the quarantine that the disease did not spread beyond the ward in which it developed. Zingher has noted a similarity between the incidence of positive Dick reactions and positive Schick reactions, in that there is a greater apparent susceptibility to scarlet fever in the poorer and more populous districts. With the wider application of the Dick test this knowledge will be greatly supplemented. It has not been observed that the presence of wounds in any portion of the body renders a person more liable to scarlet fever. Second Attacks.—One attack almost always protects from subse- quent attacks. 704 THE PRACTICE OF PEDIATRICS Only two undoubted instances of a second attack have been personally observed, one of which occurred after an interval of four months in a boy of six years, the child dying on the fifth day of the illness; the other in a girl twelve years of age, whose pre- vious attack was four years earlier. In the girl the second attack ran a typical but uneventful course. It is interesting to note that an unprotected individual may be re- peatedly exposed and only at a late period develop the disease. Thus, during an intern service in the institution referred to, where the writer cared for 108 cases ot scarlet fever, and the epidemic was severe, requiring that many children be seen several times a day, three months of daily and sometimes hourly exposure transpired before he developed unmistakable signs of the disease. Specific Skin Reactions.—In 1918 Schultz and Charlton1 described their so-called extinction test. They found that the injection of normal or convalescent serum intracutaneously at the height of the rash produced blanching of the reddened skin about the site of the injection. It remained for Mair2 to point out that the blanching power, which was not exhibited by all normal serum, was actually peculiar to serum possessing immune properties. The Dick Test.—By using the filtrate of the cultures used in produc- ing scarlet fever experimentally in man the Dicks3 were able to develop a specific skin test for immunity, similar to the Schick test for susceptibility to diphtheria. The specificity of the Dick test is now well established by numerous observers, including Williams, Hussey, Banzaf,4 and Zingher.5 As might be expected, sera of individuals giving a negative Dick test is found to cause blanching when employed for the Schultz and Charlton extinction test, and to neutralize the toxin of the filtrates of the specific streptococcus cultures; while sera of persons giving positive Dick reactions is impotent for the production of both these results. Incubation.—The period of incubation is variable. It is rarely less than five days. If an exposed child passes the ninth day in safety, the disease will probably not develop later. One case developed after twelve days’ exposure, and one on the fourteenth day following exposure. These observations were made in an institution with adequate quarantine facil- ities which removed all doubt as to any other source of exposure than the original one. So long a period of incubation, however, is exceed- ingly rare. Cases reported as developing after a very long incubation— three to four weeks—result from more recent exposure which was not known. Symptomatology.—Nearly all the characteristics of the disease are subject to wide variations. Even the rash, the most constant symp- tom, may be simulated by sepsis or produced by drugs. Among the diseases of children which we are called upon to treat there is, further- more, no other which may present itself in such unusual and peculiar ways. The three symptoms upon which some reliance may be placed are fever, angina, and the rash. Any one of these, however, may be absent lZtschr. f. Kinderh., 17, 328, 1918. 2 Lancet, 2, 1390, December 29, 1923. 3 Jour. Amer. Med. Assoc.. 82, 301, January 26, 1924. 4Proc. Soc. Exp. Biol, and Med., 21, February 11, 1924. 5 Ibid. SCARLET FEVER (SCARLATINA) 705 in the mild cases. In the moderately severe cases the onset is usually abrupt, with fever, angina, prostration, and vomiting, and after twenty- four to forty-eight hours the developing rash, which is usually fairly characteristic. The angina causes a diffuse redness of the mucous mem- brane of the fauces and tonsils, and on the soft palate above the uvula minute red points become visible which may coalesce, forming diffuse, small, injected areas, and producing a blotched appearance. There is loss of appetite and always thirst. The child is irritable, and if old enough, complains of headache and muscle soreness. The temperature furnishes a fairly accurate index of the severity of the dis- ease. The mild cases show little fever, while the severe cases almost always exhibit a high temperature. Tlius a temperature range from 103° to 105° F. will usually be accompanied by a well-marked rash and pros- tration, which tell us that the poisoning is severe. When the tempera- ture remains above 103° F., the child is very uncomfortable and com- plains much of itching. The eruption remains at its height from two to six days, which may be looked upon as the period of the rash. With a subsidence of the rash the temperature falls gradually to normal. Desquamation.—Coincident with the fading of the rash the desqua- mation usually begins. It may be delayed, however, from this time until the third or fourth week and may show great irregularity in its duration. In a very few cases the rash has lasted later than the tenth day. Illustrative Case.—During the epidemic mentioned every child in the institution was carefully inspected three times daily. At 5 p. m., the time of the last inspection for the day, a boy of two years had a temperature of 102° F., an unmistakable rash over the left buttock and thigh, and some redness of the throat. There was but little pros- tration. He was quarantined, and six hours after his isolation the rash faded abso- lutely, the fever promptly subsiding on the same day. In spite of the suspicion of a mistake in diagnosis, inasmuch as he had been placed in a scarlet fever ward and ex- posed, we had to keep him there. Greatly to our surprise, on the tenth day free des- quamation began. When uncomplicated, the average case goes on to recovery, with completed desquamation in from two to four weeks. The shedding of dead epidermis may be most variable in its mani- festations. The skin of the hands and feet has been seen to be shed like a glove “en masse/’ and yet in a case in which the rash was equally well marked no desquamation of any nature was to be observed at any time. There has been desquamation, however, although occasionally very slight, in nearly all scarlet fever cases coming under our observation. The heel and the anterior aspect of the fingers and toes are the sites usually selected when the desquamation is scanty. Second Desquamation.—Only 2 cases of second desquamation were seen. The first patient was a girl of five years, who completed the first desquamation and was free for six weeks, when the desquamation again occurred on the hands and feet and required three weeks for its completion. In the other case, that of a girl twelve years of age, the second desquamation appeared three weeks after the completion of the first. It involved only the feet and was of two weeks’ duration. The amount of desquamation bears a fairly definite relation to the severity of the rash, except in the anomalous cases. 706 THE PRACTICE OF PEDIATRICS Severity.—The illness may be of the mildest type, and impossible of positive diagnosis, or it may be so severe that the child will live only a few hours. A fatal case lasted thirty-six hours from the onset of the symptoms. The child was never conscious after the first invasion, and the temperature never below 106° F., nor could it be reduced below this point. The rash was hemorrhagic. Such cases as these, in which the system is absolutely overpowered by the scarlet fever posion, are extremely rare. The disease, when fatal, is usually so through its complications. Diagnosis.—The diagnosis in many cases is very easy. In some it is difficult, and in others impossible. Not only are the mild cases difficult of diagnosis but also the very severe cases. In malignant cases the patient may die before the development of characteristic signs, or the signs may be so masked by the severity of the infection as to render diagnosis impossible. The diagnostic features are the angina, which occasions a diffuse, intense general redness of the throat, the fever, and the diffuse blush of the skin, which in twelve to twenty-four hours develops into a diffuse punctate rash usually appearing first and most characteristically over the lower abdomen, in the groin, on the inner aspect of the thighs, and over the buttocks, and thence extending to, and involving, the entire skin surface. It has not been the rule that the rash first appears on the neck and chest, as has been claimed by different writers. The so-called strawberry tongue is of little differential value, for it may occur in many other forms of illness. Complications.—Probably no other disease of infancy or childhood is so fertile in serious complications as scarlet fever. In fact, compara- tively few die from the direct effects of the scarlet fever poison. A strep- tococcus infection of the throat is present in all cases and the throat as a culture field for the streptococcus is the great source of danger in the disease. Membranous non-diphtheric angina complicating scarlet fever has always been of streptococcal origin in our cases. On inspection, the exu- dation resembles that of true diphtheria and our only means of differen- tiation is the making of a culture. Such a membrane may involve the nasal passages, but rarely extends to the larynx. The local infection may be sufficiently severe to cause extreme necrosis. Illustrative Cases.—In one case shortly before the time set for operative removal of a pair of very large tonsils, a boy developed very severe scarlet fever. On his recovery the throat was as free of tonsil tissue as if they had been carefully enucleated. In a fatal case necrosis of the soft palate occurred, resulting in a perforating ulcer larger than a dime. True diphtheria occurs as a complication in a very small percentage of the cases. Before our knowledge of the Klebs-Loffler bacillus much was heard of diphtheria as complicating scarlet fever, because of the presence on the tonsils of membrane, which we now know to be of strep- tococcal origin. Adenitis.—From the throat the glands may be infected. The lym- SCARLET FEVER (SCARLATINA) 707 phatic glands at the angle of the jaw and the retropharyngeal glands are, by reason of their location, the most frequently involved. Suppuration of the glands and abscess are very frequent, and diffuse edematous cellu- litis of the neck is an occasional result of such infection. Cases have been reported in which the pus burrowed into the medi- astinum, causing septic endocarditis and empyema. Pericarditis and endocarditis have been very rare complications and, in the cases personally observed, have always been fatal, for the reason that such cases of streptococcal origin are always purulent. Myocarditis of a mild degree is often disclosed at autopsy. Lobar pneumonia is a very unusual complication. Bronchopneumonia is found at autopsy in nearly all the fatal cases. The development of the disease during an attack of scarlet fever is of very grave import. Otitis is a frequent and dangerous complication. If all cases of scarlet fever, the mild, the moderately severe, and severe, are included, otitis will be found in over 10 per cent. Albuminuria.—Early in the average case albumin will be found in the urine if this is repeatedly examined with sufficient care. This con- dition does not constitute nephritis, however, for albumin in small amounts is found in most diseases of toxic origin in childhood. Nephritis.—Scarlatinal nephritis rarely appears before the third week of the disease. Cases have been personally observed to develop as late as the twelfth week after the onset. The nephritis is of the glomerular type, and more likely to occur after mild infections. The first sign will usually be that of a puffiness under the eyes and about the ankles. The urine becomes scanty and high colored. This complication is referred to again on p. 713. Arthritis.—Joint complication has been present in but 5 per cent, of our cases. The arthritis is the manifestation of a local infection. There may be swelling and redness of two or more of the joints. We have never observed one joint alone to be involved. In some cases pain alone will be present, without either of the above symptoms. Illustrative Case.—A fatal case of pyemic arthritis was seen in consultation with the late Dr. Mclnerny, of New York. The joints at the knees, ankles, elbows, and wrists suppurated. Mortality.—The mortality varies greatly. Different epidemics give a different mortality. In institution epidemics the mortality is higher than among children in private life. In the New York Infant Asylum, during the service referred to, the mortality in children under six years of age was 20 per cent. In private work the average mortality ranges under 10 per cent. In greater New York the mortality rate within the past ten years has been slightly over 4 per 100,000 of population. Quarantine.—The isolation of those ill with contagious diseases is an absolute necessity for the protection of others. While it is advis- able in cases of scarlet fever to remove from the house children who have not had the disease, such removal is often impossible. It then becomes our duty to establish such a quarantine as will be effective in preventing the transmission of the infection. In order to do this, the 708 THE PRACTICE OF PEDIATRICS child and the attendant must be kept from contact with other members of the family, whether children or adults. If the residence is a complete house, one or two rooms on the top floor should be selected for the patient, the room from which he is removed being carefully cleaned and disin- fected. If the family occupy an apartment, an effective isolation is more difficult, but is by no means impossible. In such circumstances the room must be as remote as possible from the other living rooms. It should be prepared for the patient according to the instructions laid down on p. 152. Not only should the attendant not come in direct contact with other members of the family, but there must be no indirect contact through dishes, feeding utensils, clothing, or bed-linen. The dishes, knives, forks, and spoons should be placed in boiling water and in this sent to the kitchen. The clothing, towels, and bed-linen should be placed either in boiling water or in a carbolic solution—1 ounce to 2 gallons of water— before sending them to the laundry. Upon their arrival at the laundry they should be boiled at once. A chair outside the door of the sick-room may be used as a receptacle for the various articles for the patient. These are to be removed only when the person who brought them is at a safe distance. Two isolating rooms are better than one, and if there is a connecting bath-room, it is much more agreeable to the occupants. If two rooms are devoted to the patient, one is to be used for day and the other for night occupancy, the unoccupied room being freely ventilated after the removal of the child. Observing the above precautions until the child is well, we have in many instances carried through to successful convalescence cases of scarlet fever while other susceptible children have remained in the household during the entire illness without taking the disease. Illustrative Case.—An incident, previously referred to, which well demonstrates the value of proper quarantine, occurred at the New York Infant Asylum, Mt. Vernon, New York, during the senior author’s service as intern in that institution. The institu- tion was built on the cottage plan, two wards in a cottage. A colored child, an occu- pant of one of the upper wards, was discovered to be ill with scarlet fever. There was an extensive rash, considerable swelling of the cervical glands, and the whole aspect of the case was that of this disease at its height. Through the negligence of an orderly the child had probably been ill two or three days before attention was called to him; as a consequence 30 other children of the ward had been exposed. In order to prevent the spread of the disease to the other 400 children, it was decided to quarantine the ward with its children and the 4 attendants. This was done. Twenty-six children and one woman attendant developed the disease. The quarantine, on the plan above suggested, was continued for ten weeks. The 30 or more children on the ground floor of the cottage remained there as before, but no other case developed in the in- stitution. In order to prevent the spread of the contagion there was no personal con- tact with those outside of the ward, except on the part of the physician who visited them daily, but who always went properly protected. All clothing and bed-linen were boiled before being removed from the ward. The dishes and feeding utensils were likewise boiled before being sent to the general kitchen. If such isolation is possible in an institution among the careless and more or less ignorant, it certainly should be equally effective among the intelligent, who are most interested in preventing the spread of disease. When the quarantine is raised, the child should receive a bath of hot water and thorough scrubbing with plenty of soap. A few hours later a bath of bichlorid 1 : 3000 should be given. If the hair is cut short and shampooed with green soap, followed by the bichlorid, the disin- fection is more complete. SCARLET FEVER (SCARLATINA) 709 Prophylaxis.—Although convalescent serum has afforded apparently favorable results in preventing the disease in exposed persons, it may be predicted that this method offers little. The Dicks have succeeded in developing an active immunity by inject- ing their toxic filtrate into susceptible subjects, and the attempt is being made to develop this method on a considerable scale in procedure analogous to that employed for toxin-antitoxin administration in diphtheria. A most efficient safeguard is a normal throat. The presence of en- larged tonsils and adenoids doubtless increases susceptibility to the disease, and their presence adds greatly to the dangers. Treatment.—The patient must be kept in bed throughout the en- tire illness, from four to six weeks from the onset first manifested by sore throat and fever, until the desquamation is completed.. We must realize at the outset the possibilities latent in the virulence of the infection and the complications. The sick-room should be as large as it is possible for the family to supply. It is desirable that it be well lighted by two windows which will make free ventilation possible. For the latter purpose, the window- board (p. 26) answers well. There should always be a direct commun- ication with the open air, except when the child is being bathed or the clothing changed. Light and the free circulation of fresh air are abso- lutely necessary for proper management of a severe case. If possible, two rooms should be used—one for the day, the other for the night. The room which is not occupied should have the windows wide open. When nephritis, endocarditis, or otitis develop, they are the result of the scarlet fever poison or associated infection, and not due to the fact that a win- dow was left open. Clothing.—The child requires no extra jacket or wraps. The cus- tomary night-gown, with the light gauze undershirt, and the usual bed- covering, is all that is required. Urine Examinations.—The urine should be examined for albumin every day. It is excellent practice to have in the house a few test-tubes and a bottle of chemically pure nitric acid. When the busy physician has the daily specimen sent to his office or carries it home himself it is sometimes forgotten, misplaced, or lost. During convalescence, when the daily visit is not made, the nurse or some intelligent member of the family may be instructed to make the test and report if trouble is dis- covered. Because of a lack of these precautions, nephritis may easily be overlooked until puffiness about the eyes and edema of the lower extremities are discovered by the attendant after albumin has been present in the urine for several days. Diet.—For the bottle fed during the acute febrile stage the food strength should be reduced one-half by the use of boiled water. If the child is getting 8 ounces of a milk mixture, 4 ounces of this mixture should be given with 4 ounces of water. For older children the diet should be considerably restricted, not only during the acute stage, but during the entire course of the disease. During the acute febrile stage diluted milk, gruels, and orange-juice should constitute the diet. To a child from two to four years of age, 5 ounces of milk with 5 ounces of barley gruel No. 2 (see Formulary, page 94) may be given at four-hour intervals, four or 710 THE PRACTICE OF PEDIATRICS five feedings in twenty-four hours constituting an acceptable diet. Vari- ations may be made in the gruels used. Wheat, rice, and Granum may all be brought into use, made as suggested in the formulary and given with equal parts of milk. It is always well to provide for some variety in the food, in order that the child may not tire of it. The juice of one- half an orange may be given twice daily, three hours after the milk and the gruel feeding. For the sake of variety a glass of whey or kumyss, or a glass of skimmed milk containing | ounce of lime-water may occasionally be allowed. Toasted bread, zwieback, or plain crackers, dry or in diluted milk, may also be given occasionally. Milk Diet.—The extensive milk diet in the management of scarlet fever, about which we have all heard and still hear a great deal, has not been so successful as has the foregoing. The exclusive milk diet is apt to produce constipation, intestinal indigestion, coated tongue and loss of appetite; in fact, the child “grows stale” on milk, which should properly be our dietetic mainstay during the weeks that are to follow. During the post-febrile period slight additions should be made to the diet by the use of farina, hominy, wheatena, and the lighter cereals, prepared as porridge with a sprinkling of sugar and a little milk. The child’s cus- tomary diet should not be resumed until four weeks have elapsed from the commencement of the attack. If the case has been severe, showing marked systemic infection, six weeks should elapse before the full diet is resumed. Bowel Evacuation.—If at least one evacuation of the bowels daily does not take place, a soap-water enema should be given. If, on account of the diet and the recumbent position, there is a tendency to consti- pation, a glass of malted milk—6 teaspoonfuls of the malted milk to 8 ounces of water—as a part of the evening meal will be of service in reliev- ing the condition. The addition of 1 teaspoonful of cocoa will be accept- able when the taste of malted milk is objectionable. Laxatives.—As a laxative during the acute febrile stage citrate of magnesia is very satisfactory. As a rule, children like it, and to those from two to five years of age it may be given in doses of from 2 to 4 ounces. In case it is not well taken, from 1 to 2 teaspoonfuls of aromatic fluid extract of cascara may be given. Specific Medication.—There is no specific medical treatment for scarlet fever. Many cases have passed through the entire illness with- out the use of any other measures than those suggested above. Nursing.—As the course of scarlet fever is distinctly self-limited, much can be done in the most severe cases to prevent complications and to relieve the patient of his temporary burden and preserve his natural resistance. This we have done in no small degree when we have so arranged for clothing, diet, fresh air, bowel evacuation, sleep, and quiet as to insure the child’s comfort and well-being. The amount of vitality wasted by an uncomfortable, restless child in twenty-four hours may turn the case from a successful to a fatal issue. We fully believe in “spoiling” a sick child. If a child is more at ease with the mother, the mother’s place is with the child. If the mother’s presence disturbs the child, as it does in some instances, she should be kept in the background. If it is apparent that the muse selected is not SCARLET FEVER (SCARLATINA) 711 to the child’s liking, or not adapted to the case, another nurse should be secured. A physician may be obliged repeatedly to take his best nurses from children gravely ill, because the patients are irritable and unhappy under the supervision imposed. Quiet is most necessary. One person only should be allowed in the sick-room with a child very ill. Control of Fever.—It is a safe rule not to allow the temperature to go much above 104° F. A higher temperature than this necessitates an overworked heart. For the purpose of controlling the temperature, a fifteen-minute sponging every hour with water at 90° F. may be tried. Packs.—If sponging does not answer, the pack (p. 841) should be brought into use. The mere existence of a rash is no contraindication to the application of moderate cold to the skin. The pack may be used in scarlet fever, just as in pneumonia or typhoid fever. The fear that the disease may “strike in” and kill the patient is one of the many in- explicable ideas of the laity with no foundation in fact. The child is placed in the pack at 95° F. It will rarely be necessary to reduce the temperature of the pack below 80° F. If the case is of the fulminating type, with persistent high temperature, the pack may gradually be re- duced to a temperature of 70° F. In thus reducing the temperature the towel is not to be removed from the patient. He is turned from side to side and the towel moistened with water at the desired temperature. Time and again the observation has been made that a child who was tossing about the bed, delirious and sleepless, falls into a quiet sleep when placed in a pack. With a reduction of the temperature there is a corresponding diminution in the pulse-beats of from 20 to 30 a minute. Tub-baths.—The full tub-bath at a temperature of 95° F. for ten minutes at the commencement of a case in which there is a great deal of restlessness and irritability will often act most satisfactorily in quiet- ing the patient. Tub-bathing, however, requires a great deal of hand- ling of the patient, and in the cases in which there is persistent high tem- perature, and in those in which it mounts up suddenly after the bath, the pack is far the more satisfactory. In some cases with intense pros- tration, high fever and cold extremities, the warm bath—105° to 110° F. —for ten minutes will have a most satisfactory effect, the fever being thereby reduced, the child quieted, the heart action improved. Oil Inunction.—The itching and burning of the skin in scarlet fever is most distressing. This is relieved to a considerable degree by the pack. The child’s comfort will be augmented by an inunction twice daily of cold cream or liquid petrolatum. Vaselin or olive oil may be used, but they are much less satisfactory. Vaselin acts as an irritant to some sensitive skins. During the period of desquamation the oily applications largely prevent a free distribution of the scales. Stimulants.—If during sleep the pulse is over 150 a minute, and the cardiac first sound is weakened, a heart stimulant is necessary. To a child one year of age 1 drop of tincture of strophanthus at two-hour intervals, or an equal amount of the tincture of digitalis, should be given. On account of its being well borne by the stomach, the tincture of strophanthus is at times to be preferred. Strychnin is a remedy of 712 THE PRACTICE OF PEDIATRICS considerable value as a stimulant. When the pulse is soft and the heart action shows a tendency to irregularity, 1/200 grain may be given every four hours to a child from one to three years of age, and 1/150 grain to a child from three to six years of age, at intervals of four hours. Alcohol should be used only in the septic, asthenic cases when other forms of stimulation have failed. In such instances it should be used freely. In a few cases very large quantities have been used with striking benefit. One-half dram of whisky, at first given every two hours, may be increased gradually until its beneficial effects are noticed on the heart action. It is astonishing how much alcohol may be given, in a profoundly septic case, without the slightest effect except an improvement in the heart action, and a corresponding improvement in the child’s general condition. Care of the Throat and Nose.—The throat and nose demand our atten- tion during the acute stage. For the nose toilet of older children a solution of menthol and liquid petrolatum, 1 grain to 1 ounce, may be used by means of an atomizer, and for the very young by instillation with a medicine- dropper. Forcible syringing of the nose of a young child is not a safe procedure even in the most skilled hands. Local treatment of the throat depends entirely upon its condition. If the mucous membrane is swollen, edematous, and covered with a glairy, mucopurulent secretion, if there is a pseudomembrane, or if there is much pain or discomfort upon swallow- ing, the child may be made to gargle, if old enough; or, far better, the throat may be irrigated with hot saline solution at 120° F. This is done in the manner described on p. 321. Force will be required with the very young. In older children the relief from pain that is experienced from free irrigation is so great that usually the child takes the tube in his mouth gladly for the future irrigations. The use of antiseptic gargles and washes has not seemed to possess any value other than that of cleanliness, and free douching accomplishes this in a far more satisfactory manner. Suc- tion in competent hands is here a valuable aid (see p. 701). Specific Serotherapy.—Even before the discovery of the specificity of the streptococcus of scarlet fever the use of convalescent serum was carried out by various investigators in the belief that it favorably influenced the course of the disease; and in 1914 Zingher reported favorable results from administration of whole convalescent blood intramuscularly. The most promising results thus far achieved have been obtained by Dochez,1 who has been able to produce a relatively high degree of immunity in the horse to the organism which he had employed in producing the disease experi- mentally in guinea-pigs. The results already obtained by the practical use of immune serum thus obtained from the horse have been highly encouraging, and justify confident belief in the success of the method when it is more widely available. Treatment of Complications.—Cervical adenitis is a very frequent complication, and when suppuration occurs, it is most troublesome. On the first appearance of a swollen gland a cold compress should be applied and then kept on constantly day and night, until the swelling has materially subsided. The temperature of the water should be from 50° to 60° F. The compresses should be changed every thirty minutes during the day and 1 Jour. Amer. Med. Assoc., 82, 542, February 16, 1924. SCARLET FEVER (SCARLATINA) 713 at least every two hours during the night. Several thicknesses of old linen, such as are furnished by a table napkin, answer well as a medium for applying the cold. The material used should be cut of sufficient length to extend from ear to ear under the jaw. In order that the mois- ture may be retained oiled silk or rubber tissue may be placed over the dressing, and over all a thin gauze bandage pinned together on top of the head. Otitis is a complication to be looked for in cases of scarlet fever. In view of the grave possibilities of mastoid involvement, sinus thrombosis, and jugular bulb infection, the presence of pus in the middle ear should be promptly detected, and the pus evacuated by a free incision of the drum membrane. The presence of middle-ear infection may be suggested by a pain or a sensation of fulness in those old enough to locate it. In infants, restlessness, sleeplessness, or tenderness on manipulation in cleans- ing the ears may be the only objective sign of the trouble. In the ma- jority of cases of otitis none of the above signs of pain and discomfort are present. The ear involvement is suggested because of a continued elevation of temperature which is not otherwise to be accounted for. A persistent elevation of the temperature of unknown origin following scarlet fever is sufficient occasion for examination of the ears by an expert in otoscopy. As a routine precaution during the disease the condition of the drum membrane should be noted every day. The incidence of otitis depends somewhat upon the character of the epidemic, but more upon the age of the patient. The younger the child, the greater the danger of ear involvement. Many cases of deafness have had their origin in an attack of scarlet fever, and are due to somebody’s ignorance or neglect. Among 185 cases of scarlatinal otitis reported by Bezold and quoted by Holt, in 30 there was entire destruction of the membrana tympani; in 59 the perforation comprised two-thirds or more of the membrane; in 13 there were small perforations; in 44 there were granulations or polypi; in 15 there was total loss of hearing on one side, and in 6 of the cases upon both sides; in 77 the hearing distance for low voice was less than 20 feet. May, of New York, collected statistics of 5613 deaf-mutes, of whom 572 owed their condition to otitis following scarlet fever. The bacteriology of scarlatinal otitis is the same as in suppurative otitis developing with or following any other infectious disease, except that there is a greater tendency to severity because of the liability to streptococcus infection. Prompt relief demands prompt recognition of the condition of the drum membrane, with evacuation of the pus and suitable after-treat- ment. (See Acute Otitis, p. 662.) Cardiac Involvement.—Heart complications are not particularly fre- quent in scarlet fever. Nevertheless the heart should be examined daily. Such complications have been present in about 2 per cent, of our cases. Nephritis.—Early in severe infection there will often be discovered a transient albuminuria with a few hyaline casts. There may be slight suppression of the urine. Illustrative Case.—In one ease there was complete anuria at this stage of the disease. Within thirty-six hours, moreover, after the first sign of the disease in this case, the kidneys ceased to act, and on the third day the child died from the acute diffuse nephritis. 714 THE PRACTICE OF PEDIATRICS The condition of the kidney giving rise to albuminuria is best relieved through attention to the skin function by the use of a bath at a tem- perature of 105° F. every six or eight hours. The child may remain in the bath for ten minutes, during which time the skin should be vigorously rubbed with the bare hand. The tincture of aconite in doses of 1 drop, with 5 drops of sweet spirits of niter for a child eighteen months of age, will usually produce a satisfactory diaphoresis. What is known as scarlatinal nephritis rarely appears before the third week of the disease and cases occur as late as the sixth week. The management of this complication is discussed on page 497. Arthritis as a complication of scarlet fever is seen in only a few of the cases. There may be swelling or redness of the parts, or both these signs may be absent. Whether or not the swelling is present, the joints are very painful on manipulation. Affected joints should be wrapped in old linen, saturated with lead and opium solution, and the dressing renewed every six hours. The following lotion has answered well in a few cases: 1$. Mentholis 5ij Tincturse opii 3 tv Spiritus vini recti q. s. ad. 5vj Soft linen is moistened with the lotion, wrapped about the parts, and covered with oiled silk or rubber tissue. The part affected is then wrapped in flannel or cotton-wool. The lotion may be freshly applied at intervals of from four to six hours. The only objection to its use is the odor of the menthol. Internally, to a child four years of age, aspirin may be given in doses of 5 grains, with 10 grains of the bicarbonate of soda at four-hour in- tervals, four doses being given in the twenty-four hours. Salicylate of soda may be used in small doses; but, as this may be badly borne by the stom- ach, aspirin at times is preferable. Septic Rash Resembling Scarlet Fever.—This type of rash is some- times described in text-books as that of scarlet fever. An inoculation of the disease is supposed to take place through an abrasion or wound. We have never seen a case of true scarlet fever acquired in such a manner. One does see surgical cases, however, develop a septic rash which cannot be differentiated from the scarlet fever rash. In such cases the skin will desquamate on the body generally, but not on the hands and feet. There is no angina. Further, a case of this nature does not transmit the disease to others. TYPHOID FEVER Typhoid fever is not a disease common to infants or very young children, although persons of any age may acquire the disease. It has been established that the fetus may be infected by the mother, different observers having proved that bacilli in the fetal organs and blood have reacted to the Widal test. Numerous cases are reported as occurring during the first months of life, but the fact that these cases are reported singly, and that such reports are commented upon and quoted by other writers, emphasizes the truth that typhoid in the very young is extremely rare. TYPHOID FEVER 715 In a large hospital and private experience, covering many thousands of cases of acute illness in children, during a period of over thirty years, the senior author has seen but 4 cases of proved typhoid in children under two years of age. The youngest was eight months old and another ten months old. Bacteriology.—Bacillus typhosus was described by Eberth in 1880 and cultivated by Gaffky in 1884. It is short, it does not retain Gram’s stain, and grows readily upon all ordinary laboratory media. Important characteristics of the organism are its viability and its inability to pro- duce gas in any sugar medium. The Bacillus typhosus enters the human body through the gastro-intestinal tract, usually by means of polluted water, which, in turn, may contaminate milk, vegetables, and oysters. During the course of an attack of typhoid fever Bacillus typhosus may be cultured from the blood, rose-spots, feces, the urine, and exceptionally from the sputum. The bacilli are found in the blood in practically all cases of typhoid fever, most frequently during the first week, less fre- quently in each succeeding week. In the feces the organisms do not, as a rule, appear until the second week, when ulceration has begun; they thereafter remain present until convalescence is established. The urine rarely contains typhoid bacilli before the end of the second week of the disease, when they are present in about 25 per cent, of all cases. The urine may continue to show the bacilli for weeks or months after con- valescence. In the gall-bladder the bacilli have been found years after an attack of typhoid fever. Bacillus typhosus is found in pus from complicating suppurating lesions in typhoid fever, such as periostitis, osteomyelitis, synovitis, meningitis, peritonitis, and abscesses. Typhoid carriers have been estimated by Bussell to develop from about 3 per cent, of all typhoid fever patients. These persons may excrete the bacilli with the urine or feces for many years after an attack of the disease, and are, therefore, a menace to those about them. Immune bodies develop and circulate in the blood of the patient with typhoid fever. One kind of immune body is the agglutinin, the presence of which is demonstrable by the Gruber-Widal reaction. This agglu- tination of typhoid bacilli by the diluted serum of a typhoid fever patient is not usually apparent until the second week of the disease, and may be delayed until the seventh week. The reaction is present, however, some time during the attack in 95 per cent, of all cases of typhoid fever, and is, therefore, a diagnostic aid of great value. (See p. 823.) Pathology.—The lesions produced by typhoid are usually much less severe in children than in adults. Autopsies upon youthful sub- jects have at times revealed no intestinal lesions sufficiently severe to warrant the diagnosis. In nearly all cases, however, the small intes- tine is the seat of a catarrhal process, and although there may be no actual ulceration, the solitary follicles and Peyer’s patches are reddened and swollen. The spleen is almost always enlarged. Doubtful find- ings may be substantiated by cultures from the blood and intestinal contents. The origin of the typical lesion has been well explained in the fol- lowing paragraph:1 “According to Mallory, the essential feature of ty- 1 Adami and Nicholls: Principles of Pathology, 1909, vol. ii, p. 439 716 THE PRACTICE OF PEDIATRICS phoid is a proliferation of the endothelial cells through the body, a change which he thinks is due to a diffusible toxin derived from the bacilli. The lesion in question is found in Peyer’s patches, mesenteric glands, liver, and bone-marrow, as well as in the lymphatics and blood capillaries, but is proportionately more intense the nearer to the point at which the infecting agent gained entrance. The endothelial plates attached to the fibrous meshwork of capillaries proliferate, become fused into plasmodial masses or giant-cells, and act as phagocytes. They ingest the bacteria and slowly eat up the lymphoid cells, which thus gradually disappear. A few leukocytes are to be seen in the follicles, and within the crypts of Lieberkiihn, but are not an important feature. Owing to the massing of these endothelial cells within the capillaries and the consequent obstruction to the blood-supply, the parts deprived of their nutrition undergo necrosis. The focal necroses in the liver and spleen are to be explained in the same way.” Symptoms.—We cannot agree with those writers who describe urgent symptoms early in typhoid. The early manifestations in a great majority of cases consist in mod- erate fever, becoming a little higher each day, apathy, and drowsiness. The tongue is coated and there is loss of appetite. Epistaxis is a not uncommon symptom. In children systemic poisoning from intestinal sources appears to have some selective action on the nervous system; thus, disturbed di- gestion, whether acute or chronic, is productive of dreams and night terrors. Gastro-intestinal disturbances, more than any other indirect factor, are productive of convulsions. In typhoid fever the central ner- vous system, similarly, is affected, but the effect is one of depression. The child is dull and apathetic. So indefinite are the signs that a diagnosis is impossible for days, and often it is just this feature of absence of diag- nostic signs that arouses a suspicion of typhoid fever. Now and then a case is seen with stormy onset, high fever, delirium, and rapid pulse. In such cases there is usually an associated infection, such as an acute intestinal infection or one due to the pneumococcus. Nervous Symptoms.—-In mild cases the nervous manifestations may be slight or altogether lacking; or there may be apathy, drowsiness, stupor, and delirium. The temperature range and the nervous mani- festations appear to bear little relation to each other; thus, with a low temperature range there may be pronounced stupor and delirium, sug- gesting the possibility of meningitis. The Pulse.—The pulse-rate is a most characteristic sign. It is com- paratively slow, decidedly out of relation to the temperature range— slower than in any other illness excepting meningitis. The pulse shows no irregularity in force or rhythm. One may find the pulse at 110 with a temperature of 104° F. This in itself is a most suggestive sign. The typical typhoid pulse is dicrotic. The spleen is usually enlarged, the enlargement corresponding with the severity of the attack. The organ is usually palpable some time during the second week, but in mild cases may never appear below the free border of the rib. Gastro-intestinal Symptoms.—Tympanites is the rule; this condition TYPHOID FEVER 717 may be extreme or of mild degree, or it may not exist. With suitable feeding tympanites may be largely eliminated. Either diarrhea or constipation may be present. Here also the feed- ing of the patient plays an important part. Patients who are fed with large quantities of milk often have diarrhea or constipation, or the two conditions alternating, along with abdominal distention, high fever, and greater toxicity. Rose spots may be absent, few in number, or scattered over the skin surface. They appear most often on the abdomen, but frequently also on the chest and back. The Blood.—A fall in red corpuscles and hemoglobin is to be expected after the first two weeks. Leukopenia is constant and there is a relative mononuclear increase. The Widal reaction appears usually only after the first week and may be delayed until late in the course. This reaction, however, may persist for years after the attack. Positive blood-cultures may be obtained before the development of the positive Widal reaction even when the latter is obtained early in the disease. Temperature.—The temperature range is variable. The usual range is 101° to 103° F., perhaps occasionally reaching 104° F. It is extremely rare for the temperature to continue after the eighteenth day. In typhoid a very high temperature is not always a bad prognostic sign. Illustrative Cases.—In the case of a girl seen in consultation with Dr. Staub, of Stam- ford, Conn., there was a temperature range for eleven days of 104° to 106° F., and from 101° to 104° F. for ten days longer, the entire duration of temperature being thirty-six days. During the illness the child did not appear to be very ill. In the case of a boy of ten years, who showed a positive reaction, the temperature lasted two weeks, but was never above 100.5° F. by mouth. In the exceptional case of a ten-year-old girl the duration of the fever was only ten days. Complications.—The complications of typhoid in children have been exceedingly rare in our experience with the disease, and fatalities have been of most unusual occurrence. Intestinal hemorrhage of any severity is an exception, and perforation, in the case of a child, we have not known. The fact that typhoid fever bacilli may be cultivated from the blood and urine implies that infection of various organs in the body may and does occur; thus the disease may cause pyelitis, peritonitis, meningitis, osteomyelitis, synovitis, otitis, neuritis, parotitis, phlebitis, adenitis, furunculosis, and abscesses. When bronchopneumonia occurs with typhoid fever, it is usually a terminal infection. Suspicious Diagnostic Signs.—Apathy, drowsiness, a gradually ris- ing temperature curve, with diarrhea, and perhaps tympanites. Diagnostic Signs.—Positive Widal reaction; elevation of tempera- ture, and pulse slow in comparison to the temperature; involvement of the central nervous system, drowsiness, stupor, delirium, enlarged spleen, and rose spots. The Widal test may be corroborated by culturing the blood and urine and by examination of the feces. Differential Diagnosis.—Any continued fever of unknown origin, until very recent years, would have been called typhoid or malaria. It 718 THE PRACTICE OF PEDIATRICS was only a few years ago that some of our best clinicians in this country and in other lands diagnosed as typhoid every continued fever which did not respond to quinin, and for which no adequate cause could be discovered. With the exact means of diagnosis which are at our disposal at the present time there is no occasion for failure to differentiate malaria, typhoid, and the conditions with temperatures due to occult pus. The nervous phenomena of typhoid, when particularly pronounced, may, upon inspection alone, closely simulate those of meningitis. In typhoid the respirations, if slow, are regular and of even depth; the pulse is slow and regular. In meningitis irregularity or some atypical con- dition characterizes the pulse; it may be very rapid—180 to 200— with a temperature of 101° or 102° F. The spleen is not typically en- larged in meningitis, nor are rose spots present. Acute miliary tuberculosis may simulate typhoid. In tuberculosis of this form there is absence of all typhoid signs except the fever, which is usually very high in children of the typhoid age. The eruption and the mental dulness of typhoid are not seen in acute miliary tubercu- losis. Enlargement of the spleen may be present in both diseases. Mortality.—Many of the mortality tables are valueless. Statistics of cases and diagnoses antedating the Gruber-Widal reaction and the discovery of the bacillus in the blood, urine, and feces are inaccurate. Thus, in one series, in infants under one year of age, we find the mor- tality given as 50 per cent. The mortality in private cases treated in homes or private institu- tions ranges from 2 to 3 per cent. In cases treated in hospital wards or in institutional homes it ranges from 8 to 10 per cent. In 95 hospital cases Koplik lost 9 patients—a mortality of 9.4 per cent. Henoch, in 375 cases, had a mortality of 14 per cent. Antityphoid Vaccination.—The prophylactic value of antityphoid vac- cine has been abundantly established in both civilian and army practice. For an average child ten years of age one-half the adult dose should be given. Thus if 500,000,000 is given for the first dose, 1,000,000,000 for two subsequent doses at intervals of ten days, a total dosage for a child of ten years would be 1,250,1)00,000. Reaction.—A reaction manifested by slight fever and muscle sore- ness and fatigue occurs in a small percentage of cases. The local re- action is slight, although there may be pain, tenderness, and a localized infiltrated area. The neighboring lymph-glands may show temporary enlargement and be sensitive to touch. This condition need cause no anxiety. Duration of Immunity Conveyed.—According to the best observers immunity continues from two to two and one-half years, at the end of which time a reinoculation should be done. Advisability of Inoculating Children.—Children who remain at home under careful supervision will not require inoculation, as the incidence of typhoid under such conditions is very small. Those who travel about, particularly in summer, going by train or boat, living in hotels and board- ing houses, are constantly exposed to the possibilities of typhoid infection. Such children should have the advantage of antityphoid vaccination. TYPHOID FEVER 719 Treatment.—While usually the disease runs a shorter course in the child than in the adult, an attack means, at the least, several days of illness, and it may mean from three to six weeks. For this reason it is best to establish a sick-room regime, under which must be particularly considered the feeding, the bathing, the airing of the room, and the main- tenance of absolute quiet. If the patient becomes very ill, but one at- tendant at a time should be in the sick-room. Bathing.—The patient should be sponged twice a day, an ordinary cleansing bath being given. During the bath it is not necessary to un- cover the body. Parts may be bathed and dried, after which other parts may be given attention. Mouth Toilet.—Careful mouth toilet should be observed. Gingivi- tis and ulcerative stomatitis, with secondary involvement of the cervi- cal lymph-nodes, are not infrequent complications in these cases. Disposal of the Excreta.—The excreta from both bladder and intes- tine should be received in vessels containing a 1 : 1000 solution of bichlorid of mercury. Carbolic acid should not be used. The necessity for the attendants to wash their hands with soap and water after at- tending to the patient should be made very plain. Attendants should also be advised as to the proper disposal of the excreta. For children of tender age who still require the napkin it is best to dispense with the usual article and use cheese-cloth instead, several thicknesses of which may be made of the required shape and burned when soiled. The bed- linen should be changed every day. The Feeding of Typhoid Fever Cases.—Contrary to the general prac- tice, little or no milk should be given in many typhoid cases. A trial in practice of the early teaching that milk afforded the only diet suitable for this disease soon led to the discovery, on the contrary, that the less the milk given, the less was the tympanites, that without milk the tem- perature course wras lowrer, that there was less tendency to delirium, and that the duration of the case was shorter and, as a whole, less severe. In fact, these observations bear out the teaching of Seibert, of New York, who was the first to advocate the non-milk diet in typhoid fever. The diet preferred consists largely of gruels, made from cracked wheat, barley, rice, oatmeal, or any of the uncooked cereals. One ounce of the cereal is boiled for three hours in 1 pint of wrater. At the completion of the boiling, boiled w7ater is added to make the quantity of the gruel 1 pint. If the gruel is too thick for drinking, more boiled water may be added. The gruel thus prepared is used as a “stock.” It may be given plain, with salt or wdth sugar, or both. As flavoring, 2 or 3 ounces of chicken or mutton broth may be added. From 6 to 8 ounces of the gruel are given every three hours—five or six feedings in the twenty-four hours. The pa- tient is encouraged to drink water, which is given between feedings. Lemon- ade, tea, and weak coffee may also be given between the feedings. Rice or other light cereal, wThich has been boiled for at least four hours, is given once or twice daily. It is best served with plenty of butter and sugar, with the aim of increasing the caloric content of the food. The diet schedule for a typhoid patient, aged five years, would thus be practically as follows: 720 THE PRACTICE OF PEDIATRICS 6 a. m. : Eight ounces of gruel with sugar or a small amount of broth added. Zwieback or dried bread and butter. 8 a. m. : A drink of weak tea with sugar, or the whites of one or two eggs with sugar in orange juice. 10 a. m.: Farina, cream of wheat, rice, served with butter and sugar, or maple-syrup and butter. Drink of weak tea or kumyss or matzoon, or perhaps a dried milk food, such as malted milk or Nestll’s food. 2 p. m.: Eight ounces of kumyss, matzoon, or skimmed milk diluted with gruel. Zwieback or dried bread and butter if wanted. 4 p. m. : Orange-egg sherbet, or a drink of lemonade or tea and sugar. 6 p. m.: Cereal (or gruel) with sugar and butter or with broth. If skimmed milk has not been given at 2 p. m., it may be given with cereal at this time. 10 p. m. : Gruel with sugar or broth, or with wine. Later, when the tongue becomes clear and the breath loses its char- acteristic odor, scraped rare beef and soft-boiled eggs may be allowed. With the use of the more substantial foods, the number of feedings in the twenty-four hours is to be reduced to four. It will be seen that the caloric requirements, 60 to 70 per kilo, for the five-year-old child, may easily be supplied by the above arrange- ments of the feeding, although the diet as arranged may not be ideally balanced. (It would be high in carbohydrates, rather low in fat, and perhaps deficient in protein, particularly during the earlier period of the treatment.) Fat in considerable quantity is poorly digested by young typhoid fever patients. It may be given, however, in small amounts when mixed with other foods. Foods containing protein should not be given in con- siderable amount until we can predict the course of the disease. Milk, scraped beef, and soft-boiled eggs are often not well borne by young typhoid patients, and a temporary reduction of protein is not felt by them. Carbohydrates, such as the cereals and the different sugars, are readily cared for when properly prepared and administered. They supply fuel, but no toxic by-products, and do not require immediate elimination from the body. Excessive emaciation is prevented through their action as protein sparers. Mendel and Rose found that the excretion of creatin induced by starvation is inhibited in rabbits by feeding a diet of carbohy- drates, absolutely free from proteins and fats. When the carbohydrates are given in liberal amounts, the creatin entirely disappears from the urine. The creatin eliminated is not reduced by feeding a diet of fat alone or by a diet of fat and protein. Experimental interference with carbo- hydrate metabolism leads to the elimination of creatin, the presence of the creatin being due to true tissue or endogenous metabolism. Milk should not be given in any considerable amount before the temperature has been normal for one week. Even then, in a case in which no milk has been given and in which there have been pronounced elevation of temperature and intestinal disturbance, the giving of milk may cause a rise in the temperature. In not a few cases in which the temperature was running a low course—from 100° to 102° F.—without the presence of tympanites or delirium, the fever has been seen to shoot up to 105.5° F. and the tongue become furred and the abdomen distended, following the administration of milk. Illustrative Case.—A few years ago a girl twelve years of age had typhoid fever. The temperature was not high, the range being from 101° to 103° F. In fact, fever and TYPHOID FEVER 721 an enlarged spleen were the only signs of the disease, until the diagnosis was confirmed by a positive Widal reaction. The tongue was moist throughout the illness, as is not unusual when milk is not given. The family were fearful that the patient was not being sufficiently nourished. The mother had been told by a physician, a family friend, that such was the case. She begged that the girl be allowed one glass, 8 ounces, of whole milk daily. Accordingly the nurse was instructed to give the patient one glass of milk once in twenty-four hours. She did so, and in three hours after the first glass there was a rise in temperature to 106° F., with abdominal pain and distention. One bottle of the citrate of magnesia and a high enema were given, after which the disease resumed its usual course under the previous diet, without milk, the temperature not going above 99° F. after the seventeenth day. Mortality statistics do not teach us all that may be learned regard- ing the disease or a method of treatment. The time element, as related to the duration of the illness and the duration of the convalescence, is important. Observation in the milk-fed cases indicates that the illness may be more severe, increasing the danger to life, and that the duration of the illness is longer. Emaciation may be much greater, and the con- valescence consequently much more protracted than under the feeding indicated. The case in which the temperature period is cut down to fourteen to twenty days, and in which there is little emaciation and a prompt convalescence, should not be put in the same class with the case in which the fever lasts from thirty to fifty days or longer, with a con- valescence of three or four months, although both patients have had typhoid fever and both have recovered. It is argued that milk constitutes the ideal diet, for the reason that it contains all the nutritional elements required by the organism—fat, protein, carbohydrate, and mineral salts—which is the truth. It is further claimed that milk may be taken in large quantities and be readily digested, which is not true in the case of sick children. The addition of pepsin, hydrochloric acid, etc., has been of no value. In order to have a short case and a mild case the abdomen must be kept flat. Tympanites is an indication of danger, regardless of how it is produced. On the milk diet tympanites is the rule. On the mixed diet suggested it is the excep- tion. So long as one can keep the belly flat he may feel that he has the case reasonably in hand. The High Caloric Diet.—The applicability of high caloric feeding in typhoid fever, of which practice Coleman has been a pioneer advocate, seems to be unquestioned by those who have given this method a trial. The precaution, however, has been generally observed by those who have reported success, of giving the large allotment of food requisite to com- plete the assigned calories in the form of such articles as sugar, cereals, egg, and a moderate amount of cream, all of which are fairly well tol- erated by most patients. We have had but little experience with this method. It would seem that in spite of its very apparent advantages such feeding necessarily imposes upon the physician extra watchfulness for the occurrence of untoward symptoms such as tympanites, consti- pation, and high fever. Drugs.—With the so-called intestinal antiseptics in typhoid fever experience has been most unsatisfactory so far as concerns their in- fluence upon the disease. If there is constipation, the citrate of mag- nesia, from 4 to 6 ounces, given cold, is grateful to the patient and usually proves effective. If the bowels do not move once in twenty-four hours, 722 THE PRACTICE OF PEDIATRICS a high enema should be given. The digestive capacity is indicated by the condition of the tongue and may be improved by the use of dilute hydrochloric acid and the tincture of nux vomica. The following will be suitable for a child from five to ten years of age: 1$. Tincturae nucis vomicae. gH- xlvnj Acidi hydrochlorici diluti gtb exx Glycerini • 3jss Aquae destillatae Q- s- a(b 51V M. Sig.—One teaspoonful in water after each meal. As many as four bowel passages in twenty-four hours may occur without harm to the patient. In fact, from two to four may be con- sidered necessary to maintain free drainage. When there are more than six in twenty-four hours, loose and watery in character, the loss of fluids sustained may be a serious factor in the case, in causing a concentration of the blood, with corresponding concentration of the poison, as shown in the marked general toxemia. Diarrhea in typhoid is best controlled by the use of opium combined with bismuth. To a child from three to five years of age the following may be given: 1$. Pulv. ipecacuanhae et opii gr. x Bismuthi subnitratis gr. c M. Div. et ft. chart. No. x. Sig.—One every three hours until the stools diminish in frequency, then at intervals of six to twelve hours if necessary. For children from one to three years old the dose of Dover’s powder should be reduced one-half, the full amount of the bismuth being given. The amount required to keep the diarrhea under control will soon be learned. Of course, constipation must not be produced, for if a free bowel action is interfered with, there will be increased prostration and higher temperature. Control of the Fever.—A temperature at or below 104° F. need not be interfered with in the great majority of cases. Of course, a very deli- cate child with a weakened heart action may require the use of anti- pyretic measures before this temperature is reached. This necessity, however, is unusual. When the temperature is above 104° F. the patient does better if proper means are used for its control. Antipyretic drugs are rarely given. Quinin has never proved of the slightest value, even when given in large doses—15 or 20 grains in twenty- four hours to a child five years of age. The coal-tar products, such as phenacetin, may be used in small doses without harm if hydrotherapy is not applicable, as in a case recently seen in a remote country district. Illustrative Case.—The patient was a boy six years of age. He was delirious at times, tossing almost constantly about the bed, and sleeping but little, with a tem- perature ranging from 105° to 106° F. The disease period was the latter part of the second week, and the patient was becoming rapidly exhausted. The parents, densely ignorant, refused to allow the bath or pack. Sponging, which was carried out indif- ferently, had not the slightest effect on the temperature and appeared to excite the patient. It was suggested to the attending physician that he give 2 grains of phen- acetin and | grain of the citrate of caffein at intervals of three to six hours. From four to six powders daily were required to keep the fever within the desired bounds and the skin moist. This medicine had a decidedly quieting effect upon the patient, his TYPHOID FEVER 723 heart action was in no way unfavorably influenced and he made a complete recovery. Had the great restlessness, the loss of sleep, and the delirium continued undoubtedly there would have been a fatal termination. While there is much truth in what has been written concerning the depressing effects of the coal-tar products, and while the dangers from their excessive use are realized, on certain occasions they are a neces- sity. One cannot help feeling that the dangers have been exaggerated. Probably the diseases in which the use of such drugs is most dangerous are pneumonia and the inflammatory conditions of the heart. Heart Stimulants.—If the heart, by the rapidity of its action, shows signs of failure, the tincture of digitalis is our best remedy. When there is irregularity in force and rhythm, strychnin should be used. A child from five to ten years of age may be given 2 drops of the tincture of dig- italis or strophanthus at intervals of twTo to four hours. Strychnin, 1/50 grain, at intervals of three to four hours, may be given for the same age. Alcohol should not be given as a heart stimulant until other means have failed. It is a drug to be used only in conditions of great stress. Its function is to carry us over and out of difficult places, and it may be given in the form of whisky or brandy, 1 to 3 drams at intervals of two to four hours for children from three to ten years of age. Its continued administration for a considerable period is not to be advised. In any disease it is difficult to lay down definite rules for the admin- istration of heart stimulants. They are used with the hope of producing a definite effect, and when such effects are produced, a larger quantity should not be given. It is best always to begin with small doses and gradually increase until the desired results are apparent. Hydrotherapy.—Pyrexia is best controlled by hydrotherapy. Sponging with lukewarm or cool water may be tried, and if the case is not severe, this may answer. The child may be sponged with water at from 80° to 70° F. for one-half hour out of every four to six hours. Sponging, however, even if it controls the temperature, may not be the best means of using water for this purpose, for the reason that many children object to it, and in consequence the sponging disturbs them, increasing their irritability and reducing their vitality. The use of the bath for the reduction of fever in children has proved disappointing. They invariably object to it, the bath excites or frightens them, and, as a rule, particularly in the very young and delicate, the re- action following is poor. Moreover, the bath necessitates a great deal of handling, undressing and dressing, and therefore tires the patient. Reduction of the temperature by means of a rectal irrigation with cool water has its advocates. If the temperature is running high and intestinal lavage is indicated for reasons other than the temperature, lavage may be used, the water being of a lower temperature than that of the body, though never lower than 80° F. Without a high body temperature, however, and other indications as well, irrigation is never advisable. It causes straining, excites the child, and thus in- creases the danger of hemorrhage and perforation. Furthermore, such irrigation is a very indifferent antipyretic, even when used as cold as 75° F. By far the best means of reducing the temperature in children is 724 THE PRACTICE OF PEDIATRICS the cool pack (p. 841). Its advantages are that it causes no fright or shock to the child. He may be placed in a towel, which has been wet with water at 95° F. The only manipulation necessary is to turn him from side to side, so that the towel may be kept constantly wet with cool water at the desired temperature. The pack more effectually controls the temperature than does either sponging or the tub-bath. As sug- gested elsewhere (p. 841), the child should be removed from the pack when his temperature falls to 102° F. Hemorrhage and Perforation.—Hemorrhage has not occurred in any children’s cases personally observed in which the non-milk diet was given. In the event of hemorrhage the cold coil or the ice-bag should be applied and Dover’s powder given in full doses to control peristalsis. In case of perforation, operative procedure is to be resorted to, but this holds out little hope. Children bear abdominal operations badly, and, considering the exhausted condition of a young child in the third or fourth week of a severe typhoid, the outlook is most unfavorable. Malaria is caused by Plasmodium malariae, a protozoon discovered by Laveran in 1881. Species.—Three species of plasmodium are recognized, one caus- ing tertian malarial fever; another, quartan malarial fever, and another, malaria of the estivo-autumnal type. The tertian malarial parasite, which is the most common form, com- pletes its development in the blood in forty-eight hours, and produces a malarial paroxysm every second day. When fully grown the tertian parasite is much larger than the quartan variety, which sporulates in seventy-two hours. The estivo-autumnal parasite produces the remit- tent form of malarial fever, with varying intervals between the par- oxysms. The characteristic form of this plasmodium is the pigmented crescent. The plasmodia of malaria enter the red blood-cells and live at their expense. The resulting anemia is due to the destruction of the large number of erythrocytes, the parasites deriving their pigment from the hemoglobin of the red corpuscles upon which they have fed. For details concerning the morphology and biology of the organisms the reader is referred to standard works on clinical pathology. Transmission.-—Malaria is transmitted from one human subject to another by the bite of the Anopheles, a species of mosquito. The fully developed parasites are most readily found in the blood an hour or two before the onset of the paroxysm. Craig has stated that in malarial localities children suffer much more severely from the disease than do adults, and that malaria is often latent in young subjects. The disease may occur in very young infants, but is always of postnatal orign. Thayer and others have shown conclu- sively that malarial parasites are not transmitted through the placental circulation. Malarial fever contracted in New York City is of very unusual oc- currence. Patients coming under observation have, with few exceptions, resided elsewhere, or contracted the disease while in the country during MALARIA MALARIA 725 the summer. Every autumn a few cases of such origin are treated. They are usually of the tertian type. Pathology.—The most marked pathologic changes in malaria are found in the blood, since the plasmodia feed upon the red blood-cor- puscles. As a result, there is a marked reduction in the number of ery- throcytes and in the amount of hemoglobin; there is, further, the pro- duction of a large amount of black and brownish-yellow pigment. The leukocytes are also decreased in number, while there is a relative increase of large mononuclear cells. At autopsy upon patients dying of pernicious malaria characteristic lesions are found in the brain, spleen, and liver. The brain usually shows congestion and capillary hemorrhages due to blocking and rupture of the capillaries by plasmodia and pigment. There may be pigmentation of the gray matter. The capillaries contain infected blood-corpuscles, free plasmodia, free pigment, macrophages often large enough to block the vessel, and pigmented leukocytes. The nerve-cells show marked degenerative changes. The liver is enlarged, fatty, pigmented, and congested. In the capil- laries malarial plasmodia and pigment are seen within macrophages, but only very few plasmodia are found within red blood-cells. The liver- cells are degenerated, and sometimes pressed out of existence by the distended capillaries. Areas of focal necrosis occur with an increase in the connective tissue around them. The spleen is enlarged and pigmented, and the pulp is soft and dark colored. The venous sinuses are congested, and there are many plas- modia free in red blood-cells, in macrophages, and in smaller cells; there is also free pigment. The splenic connective tissue is increased only in those cases in which repeated attacks of malaria have occurred. The other viscera do not show specific lesions of any kind. All the capillaries contain malarial plasmodia, and there is present more or less pigmentation. The epithelial cells of the kidneys and adrenals are usually degenerated as the result of the toxemia. The heart may be flabby and anemic. The lungs may show congestion, edema, or broncho- pneumonia. Symptoms.—The symptoms vary somewhat with the age of the pa- tient; thus, an infant, instead of giving evidence of a chill, which signals the onset in older children, becomes cold, blue, and pinched in appear- ance. Vomiting or convulsions may take the place of a chill. What- ever the nature of the immediate onset, fever follows, which rarely con- tinues longer than five or six hours. This stage may not be followed by sweating. About the same time, on the following day or the day after, the same phenomenon is repeated. The patient is very comfort- able between the seizures. Physical examination of the patient will reveal enlargement of the spleen. The blood findings have been mentioned under Pathology. In neglected cases signs of malnutrition rapidly develop regardless of the age. They differ in no way, however, from those dependent upon febrile conditions due to other causes. The extreme variability in size of the spleen as a result of malaria is not popularly appreciated. 726 THE PRACTICE OF PEDIATRICS Illustrative Case.—A fifteen-month-old Armenian boy, who had contracted malaria at eight months of age and had been given no regular treatment, came under the care of the junior author with malarial organisms in the blood, an erythrocyte count of 3,080,000, and a hemoglobin percentage of 35. The spleen was found upon careful pal- pation to extend to the anterior superior spine of the ileum in the nipple line, and to about 1 inch below the umbilicus in the midline, the arc of the lower border extending to about 1 inch below the midpoint of a line joining the anterior superior spine and the umbilicus. Response to treatment was immediate, and after the expiration of a little over a year the spleen was palpable only slightly below the ribs. The possibility of at first confusing the picture in such a case with that of primary splenic disease is readily apparent. Relapse.—When relapse occurs, it means one of two conditions— reinfection, or a case not cured. A relapse after weeks or months is not uncommon. Very frequently in cases which have been treated with quinin for only a week or two until the active symptoms subside, after a long period, another sharp attack results. The manifestations are occasionally milder. There is, perhaps, a low periodic temperature with- out chill, the temperature not reaching a point above 101° or 102° F. Time and again this feature of the disease has been evident. These cases represent what is sometimes designated as chronic malarial poisoning or persistent malarial infection. In non-malarial sections reinfection is an improbability. Diagnosis.—The positive diagnosis of malaria depends upon finding the malarial organism in the blood. This is, as a rule, possible only when quinin has not been recently given. The next best means of diagnosis consists in the use, in suspicious cases, of adequate doses of an assimilable preparation of quinin. An immediate control of the temperature is then strong presumptive evi- dence that malaria has existed. When full doses of quinin do not control the temperature, this fact usually means that malaria does not exist and that there is other cause for the illness. Differential Diagnosis.—There are probably very few diseases with fever which have not many times been confused with malaria. In fact, the erroneous diagnosis of malaria has probably been made more often than all other diagnostic errors combined. There are many conditions in which there may be a remittent temper- ature period, and which may be looked upon as malaria. An enumeration is unnecessary. Probably elevation of temperature due to occult pus is responsible for more diagnoses of malaria than is any other form of fever. Influenza, typhoid fever, pyelitis, tuberculosis, and periodic fever due to fatigue often evoke the mistaken diagnosis of malaria. With blood examinations and the various newer diagnostic methods there is no occasion for errors in differentiation. Prophylaxis.—This consists in keeping the child free from the Anopheles mosquito. The administration of quinin in malaria-infected communi- ties for purposes of prevention of the disease is a common and justifiable practice. Treatment.—When it is demonstrated that malaria exists, quinin should be given in what may be considered large doses, if we are to use The adult for comparison. Children tolerate quinin well. In fact, a much larger amount comparatively is required than for adults. In giv- ing quinin to young children, however, care must be used lest it excite MALARIA 727 vomiting, and for this reason it should be given after meals in solution or in capsule. An excellent menstruum is a preparation of yerba santa, known as Yerbazin.1 A child under eighteen months of age will re- quire from 8 to 12 grains of quinin daily. Two to 3 grains of the bisul- phate should be given at a dose, not more than four doses being given in twenty-four-hours. When the writer was resident physician at the New York Infant Asylum, then located in southern Westchester County, New York, there was a great deal of malaria among the women and children inmates. In that institution he repeatedly gave infants under four months of age 8 grains in twenty-four hours. In some cases at this age a larger quan- tity—10 to 12 grains—will be required. Quinin chocolate tablets are sometimes used for children. In using these tablets it must be remembered that the contained quinin is in the form of the tannate, and that 1 grain of the tannate represents about | grain of the sulphate. If sufficient quinin to be of value is given in this form, the large amount of chocolate in the tablet will almost surely upset the digestion. Lilly’s “coca quinin” is a liquid, chocolate-flavored preparation apparently less likely to disagrees To children under one year of age with whom Yerbazin may disagree because of the sugar which it contains, the bisulphate may be given in solution in distilled water, followed by a teaspoonful of orange juice. For older children—from two to six years of age—from 15 to 30 grains daily will be necessary to control the disease. To these, as to the younger children, this drug should be given in one of the palatable liquid forms unless the child can be taught to take a capsule, when the quinin may be given in 3-grain doses at two-hour intervals until the prescribed daily amount has been taken. The giving of a large dose of quinin a few hours preceding the ex- pected chill does not answer well in treating children, as a large amount given at one time may frequently cause vomiting. Special Methods of Administration.—The use of quinin by inunction or by the rectum has not been satisfactory. Its use by these methods was attempted at the Infant Asylum in a great many cases when diffi- culty was experienced in the gastric administration. Illustrative Case.—With but one patient, aged two years, was it necessary to resort to hypodermic medication. The blood in this case showed the tertian parasite, and the disease resisted the internal use of quinin in large doses, but responded promptly to the muriate of quinin given hypodermically, 7 grains being used at one injection. There was no abscess at the site of the injection, and the child was permanently cured. To be sure, the administration of quinin was continued by the mouth, but the dosage of 16 grains daily was now apparently effective, where previously it had failed. Recurrence.—The use of quinin in malaria should not be stopped abruptly upon a cessation of the fever. It is advisable to give the drug in full doses for one week after the temperature fails to rise unless there is a subnormal temperature, in which event the drug should be reduced one-half or temporarily discontinued. It is a difficult matter to deter- mine when a case of malaria is cured. Time and again, weeks after it was supposed that a patient was well, a recurrence of the paroxysm took place. How often this was due to reinfection, and how often to the old 1 Made by Lilly & Co. 728 THE PRACTICE OF PEDIATRICS infection which had not been entirely eradicated, it is difficult to say. We are inclined to the belief, however, that in many instances the plas- modium had remained inactive in the spleen in spite of the return of that organ to nearly its normal size, for the reason that the recurrence of symptoms sometimes took place coincident with some other illness with fever, such as tonsillitis or acute indigestion. Experience with recurrences of the disease has been such that, after an attack of malaria it is customary to direct that the child be given quinin for one week out of each month for an indefinite time—at least for a year following the original attack. Illustrative Case.—A girl five years of age had repeated attacks for two years before coming under observation. The mother was instructed to give the child 12 grains of the bisulphate daily for seven days out of each month. This, without a change of residence, was sufficient to prevent a recurrence during the fifteen months which followed. INFLUENZA (LA GRIPPE) Influenza is an acute infectious disease commonly ascribed to Bacillus influenzse, first described by Pfeiffer as a result of his studies during the great pandemic of 1889-90. Bacteriologic Etiology.—It is a slender, non-motile rod, which stains deeply at the poles, does not retain the Gram stain, and is very pleo- morphic. Its one unvarying characteristic is its utter inability to grow in media which do not contain hemoglobin. On agar mixed with human, pigeon’s, or rabbit’s blood, its cultivation is an easy matter. The col- onies are small and dewdrop-like, they do not coalesce, and they do not cause hemolysis in the surrounding medium. Mode of Entrance.—It is the rule for the influenza bacillus to enter the human body through the upper respiratory tract, whence it may travel down into the lung, causing bronchitis or bronchopneumonia. In comparatively few cases it is the cause of otitis media. General blood invasion with Bacillus influenzse is a rare condition, which is usually, but not invariably, accompanied by purulent inflammation of one or more serous membranes—meningitis, pleuritis, pericarditis, peritonitis, arthritis. Since the pandemic of 1918 views concerning the etiology of influenza have been greatly modified and by many observers Pfeiffer’s bacillus is no longer credited with being the specific cause. Undoubtedly an organ- ism productive of a disease of such definite epidemiologic features and symptoms as those of the great pandemics of "flu,” differs from that causing ordinary “grip.” Whether the role of Pfeiffer’s bacillus like that of the pneumococcus and streptococcus may not be that of a sec- ondary invader is thus open to question. In any event, until our know- ledge is more accurate, distinction between pandemic influenza and the other forms of grip is a difficult problem. Source of Infection.—The source of infection is contact with an acute case of influenza or with a carrier. In either instance the secretions from the nose or bronchi contain the bacilli in a moist state. The organ- isms do not resist drying long enough to make clothes or linen a prob- able source of contagion, but they do remain viable for months in the bronchial secretion of cases of influenzal bronchitis, with or without INFLUENZA (LA GRIPPE) 729 bronchiectasis, and they have been found there six months after an at- tack of pertussis (Davis). The work at the New York Babies’ Hospital (Wollstein) has shown that the influenza bacillus is present in the bronchial secretion of young children far more often than is usually known, and that it is not pres- Fig. 118.—Temperature chart. Prolonged influenzal infection. ent as a saprophyte. Patients suffering from tuberculosis are very prone to infection with influenza. It may, in such cases, by causing a terminal bronchopneumonia be the actual cause of death. Age.—All ages are susceptible, particularly infants under one year. Pathology.—Influenza produces no distinct lesion of its own. In the respiratory tract, where the bacillus is most active, there may be Fig. 119.—Prolonged influenzal infection.—(Continued.) only the changes characteristic of bronchitis or there may be a broncho- pneumonia due to Bacillus influenzae in pure culture. The bacillus is most fertile in its power of producing lesions in various organs, but these lesions in no sense differ from those produced by certain other forms of infection. Incubation.—The period of incubation may be very short. It is rarely longer than seven days, and may be but one or two. 730 THE PRACTICE OF PEDIATRICS Symptoms.—The onset of influenza is usually with sneezing, slight conjunctivitis, and cough. There may be a moderate fever—from 100° to 103° F. or higher. The throat is reddened, and there may be a few coarse rales in the chest. The symptoms subside, and the child is well in five or six days. After the second year children complain of head- Fig. 120.—Prolonged influenzal infection.—(Continued.) ache and muscle soreness; there is also a failure of appetite. This rep- resents a mild attack of the type seen in a great majority of the cases. Severe cases show the above signs, with the exception that there are higher fever and much greater prostration. Convulsions are unusual, but headache and extreme restlessness are often present. Fig. 121.—Prolonged influenzal infection.—(Continued.) Cough.—The cough in the severe type is often most troublesome. The most severe coughs do not occur, necessarily, when bronchitis is a complication. The hard, persistent cough, without expectoration, without rales, or with but a few rales in the chest, may be said to typify INFLUENZA (LA GRIPPE) 731 the cough of influenza. Every year we see patient after patient who has the nagging tracheal cough not only during the attack, but some- times for weeks afterward, without a sign in the throat other than per- haps unusual redness, and without a chest sign. The influenza bacillus seems to have a special tendency for localization in the trachea. Gastro-intestinal Manifestations.—Occasionally grip is ushered in with pronounced gastric disturbance indicated by nausea and vomit- Fig. 122.—Prolonged influenzal infection.—(Continued.) ing, no food being retained for twenty-four to forty-eight hours. Pro- nounced intestinal disturbance is by no means an unusual evidence of infection with the influenza bacillus; there may be diarrhea without any evidence of involvement of the intestinal structure, or there may be colitis with tenesmus, and mucus and blood in the stools. In not a few cases the so-called complications are the only manifestations of the Fig. 123.—Prolonged influenzal infection.—(Concluded.) infection. This has led writers to describe a “grip colitis,” a “grip gas- tritis,” a “grip pyelitis,” etc. The temperature characteristics of influenza are peculiar. There is a tendency to wide, irregular variations from normal to 105° or 106° F. and back again. One repeatedly observes temperature ranging from 100° to 103° or 104° F. for six or eight weeks (Figs. 118-123), without other lesion than that of a catarrhal bronchitis. A peculiar feature of these uncomplicated grip cases is the height to which the temperature will rise 732 THE PRACTICE OF PEDIATRICS daily and its long continuation for many days with insignificant signs of illness and absence of effects on the patient. Fatal Cases.—Fatalities from uncomplicated influenza are unusual. Illustrative Cases.—Two cases of grip in infants, in which the diagnosis was made by exclusion and verified by autopsy, occurred at the County Branch of the New York Infant Asylum during the winter of 1888 and 1889. which, it will be remembered, was the time when grip first visited this country in epidemic form. These healthy, breast- fed babies were taken with the disease, together with about 40 other inmates, mothers and children, in one of the large wards. The infants in question, aged three and four months respectively, were stricken suddenly with high fever and marked prostration. They quickly went into a condition of collapse, and both died in less than thirty-six hours from the onset. The autopsy failed to show any pathologic change other than a slight hypostatic congestion of the lungs. Complications.—The influenza bacillus alone may produce otitis, meningitis, pericarditis, periarthritis, peritonitis, and nephritis of the hemorrhagic type. The chief danger attending its invasion of the body is its ability to prepare a field for the development of other pathogenic organisms. The most frequent complication of grip is bronchitis, and that causing the most deaths is bronchopneumonia. Suppurative otitis is not an infrequent complication; perhaps it would be .better to class it as a grip sequela. Among 72 cases of acute sup- purative otitis referred to elsewhere, 59, or 81.9 per cent., occurred with or followed immediately upon an attack of grip. Patients who, after an attack of grip, run a temperature without any apparent cause, should be examined by a skilled otologist. Adenitis is a complication in many cases. Endocarditis associated with grip is not infrequent. The Kidneys.—In nearly all cases of severe infection a slight amount of albumin is present in the urine during the entire period, and occa- sionally, in a few cases, hyaline and granular casts are found. The irritation is only of temporary duration, and subsides after a few days. In a very large experience with all types of influenza we have never known the association with grip of acute nephritis such as occurs with scarlet fever or the other exanthemata. Every year we see cases of acute hemorrhagic nephritis complicating influenza. These cases are peculiar in that there is a large amount of blood with a few hyaline and epithelial casts. There is little or no sup- pression of the urine and no edema or sign of nephritis except the urinary findings. We have never lost such a case, although microscopic blood and casts have been present in the urine for several weeks. Duration.—The duration of influenza may be two or three days or it may be two or three months. One attack of the disease confers no im- munity. The long-continued cases are those of reinfection and recrudes- cence. Prognosis.—The prognosis of influenza is favorable in the absence of complications. With complications the outcome depends upon the nature of the associated disease. Further, it is to be remembered that, as a complication of bronchitis and pneumonia, influenza supplies a decided additional danger. Diagnosis.—From simple internal colds a differentiation may be INFLUENZA (LA GRIPPE) 733 impossible even by a bacteriologic examination. In influenza there is a tendency to chronicity and reinfection, with widely fluctuating tem- perature, irregular as to rise and fall. It seems most difficult for the patient completely to recover. Meningitis, malaria, and typhoid fever may be confused with grip, but may be readily differentiated by the well-known diagnostic methods. In any case of influenza the ears should be subjected to daily examination, as otitis may cause an elevation of temperature identical with that of a protracted case of uncomplicated influenza. Pyelitis should always be excluded. Sequelae.—After even a moderately severe attack of grip the patient is left in a condition that is peculiar to this disease and none other. He is habitually tired, easily fatigued upon slight exertion, shows but little tendency to take up active play, and, if older, finds school work difficult. In a large proportion of cases there is a slight elevation of temperature nearly every day—rarely higher than 101° F. A feature of these temperature cases is that the attack may not have been at all severe. Every winter and spring the writer is repeatedly consulted about the ten- dency to elevation of temperature after grip. In some cases the tem- perature will continue for months. It will be normal—98.5° to 99° F.— in the morning, perhaps 100° F. or thereabouts at noon, and 101° F. or a fraction higher at night. It rarely reaches 102° F. The peristent tem- perature cases are not due to disease processes or to the presence of the influenza bacillus in the bronchial tract, as has been claimed, but to constitutional weakness and fatigue. In some wray, through the action of the toxins of the disease, the heat-regulating center becomes involved, and through activities which ordinarily would not produce any effect an influence is exerted causing an elevation of the temperature. That a portion of this deduction is correct may be readily proved by keeping these patients quiet in bed for three days, and taking their temperature at the usual intervals, morning, noon, and night (6 p. m.). It will be found, if they are kept quiet and the bowels active, that the temperature will remain within the normal limits—not above 99° F. This has been demonstrated in a great many cases. If fever continues uninfluenced, there is a discernible cause wdiich should be discovered. After grip, because of the child’s low physical state, he is often urged to take more food than he can assimilate, and there may be a mild degree of intestinal indigestion, producing sufficient toxic effects to cause the temperature, yet unobserved because of the absence of active symptoms. We have known the free use of milk and cream to produce a slight persistent ele- vation of the temperature after grip. Tuberculosis of the bronchial glands may produce a similar but less persistent temperature range. Quarantine.—Individuals with influenza should be quarantined (p. 707) from other members of the household. Older members of the household are often the bacillus carriers and infect the younger members. One attack of grip confers no immunity upon the patient; in fact, patients apparently reinfect themselves. For this reason we always advise that two rooms be used, when possible, one for the day and one for the night, the room not occupied during the day being aired for several hours with all the windows open. After recovery the sick-rooms should be thoroughly aired and cleaned. 734 THE PRACTICE OF PEDIATRICS Treatment.—The individual treatment is symptomatic. The rhinitis and bronchitis are treated as if the condition were not grip. The management of an otitis, pneumonia, bronchitis, or colitis as- sociated with or following an attack of influenza, differs in no way, so far as the immediate treatment of the complication is concerned, from that which would be advised if the case were independent of the influ- enza bacillus. The case, as a whole, however, will require closer watch- ing, and on account of the greater prostration, better feeding and freer stimulation. The hard, dry, teasing, tracheal cough associated with and following many cases of influenza, is sufficiently troublesome to require special men- tion. In this condition codein should be used in sufficient dosage partially to control the cough. The cough is difficult to relieve for the reason that the mucous membrane of the trachea is deeply congested. The infection, aided by the persistent cough, keeps up and adds to the conges- tion; and the irritation thus produced again tends to a persistence of the cough. This is a condition where opium is not only justifiable, but absolutely necessary, in order that sufficient rest of the parts may be se- cured to allow resolution and control of the infection. Vapor.—Charging the air with vapor, producing an artificial hu- midity, greatly lessens the irritating effects on the mucous membrane of the ordinarily dry air of the living room, and relieves the cough. External Treatment.—A preparation of mustard—1 part flour to 2 parts mustard—suitably mixed and applied to the chest for five to fifteen minutes at bed-time, will often insure a better night than would result were the application not made. Change of Climate.—When possible, patients who show pronounced systemic depression and who fail to regain their usual physical vigor should have the benefit of a change of climate. A change of a few weeks will ordinarily completely restore the patient to his normal health. When at home, or elsewhere, convalescent grip patients who show slow response to treatment should have their activities carefully advised; they should not be allowed to arise before 10 in the morning, should have a midday rest of two hours, and should retire between 6 and 7 o’clock. Drugs.—Small doses of quinin, 1 to 2 grains at two- or three-hour intervals, have given better results in hastening a return to health than any other form of medication. If there are malnutrition and anemia, the measures laid down under the respective headings may be applicable to these patients. RHEUMATIC FEVER (ACUTE RHEUMATISM) Acute rheumatism is a rare disease in young children. Although it is properly not to be regarded as a transmissible disease, its infectious origin, which seems unquestionable, justifies discussion of the condition in this chapter. Disorders described as rheumatism in infants and chil- dren under two years are usually scurvy or infectious peri-arthritis. The latter is not at all unusual, and the possibilities of scurvy are always with us. Among 1027 cases of rheumatism, Still saw none under two years of age. Our own cases have all been in children after the third year. The majority of the cases occur between the fifth and ninth years. RHEUMATIC FEVER (ACUTE RHEUMATISM) 735 It is a mistake to designate rheumatic fever or acute rheumatism as “acute articular rheumatism,” as we see many cases in which the joint symptoms play a slight part, or no part at all, the heart bearing the brunt of the attack. Repeatedly, endocarditis or pericarditis has been the main manifestation of the disease. Illustrative Cases.—Case 1.—A boy came to the Out-patient Service at the Babies’ Hospital because of sore throat and a temperature of 101° F. There was a very mild tonsillitis, and for one night there had been pain in the left knee. An examination of the heart showed an extensive endocarditis involving both the aortic and mitral valves. Case 2.—A girl, four years old, subject to periodic colds and asthmatic bronchitis, had a mild seizure of this nature, requiring that she remain in bed for a few days. Dur- ing examination of the lungs a soft systolic cardiac murmur was detected. Three days later pain and swelling appeared in a knee-joint. A polyarthritis followed, involving in all nine joints. In this child the heart involvement preceded the joint symptoms several days. It is not at all unusual to see endocarditis in the offspring of the rheu- matic, without the previous existence of a painful joint. These cases, however, will afford the history of chorea or recurrent spasmodic bron- chitis, frequent anginas, periodic gastric or intestinal crises, or growing pains. In fact, endocarditis is far more often the manifestation of acute rheumatism than is inflammation of the joints. On the other hand, many cases are seen in which the heart remains free, with the joint involvement of a most urgent nature. Etiology.—That acute rheumatism is a manifestation of some form of infecting agent, the majority of the profession are agreed. It will prob- ably be demonstrated that more than one infecting agent may cause acute rheumatism in a child predisposed in the manner that we shall attempt to describe presently (p. 738). Perhaps it will be proved that both bacterial and other toxic agents may cause the disease. The discovery of the specific infecting agent in acute rheumatism is, however, still a problem. That the tonsils often constitute the atrium of the infection is well established. Similarly, a diseased sinus or antrum or adenoid growth may be a site for establishment of a focus from which rheumatism is derived. Numerous writers affirm that diseased teeth and infected adjacent structures are often sources of infection. Symptoms.—(For Endocarditis, see p. 418.) Like all diseases of an infectious origin, acute rheumatism may be so mild as to escape notice, or it may be most severe. In the joint type the first symptom is pain in the joint; this may be very slight, or it may be most intense—so in- tense that the bed-clothing may not touch the parts without increas- ing the pain. Between these two extremes there are all degrees of in- volvement. There may be neither swelling nor redness, or the swelling may be extreme, with marked redness, the part’being twice as large as its uninvolved fellow. One joint or several may be affected. The pain and swelling usually begin in one, and subsequently affect others. The first joint to become inflamed is usually the first in which the inflam- mation subsides. In no other joint affection does the pain compare in severity with that of acute rheumatic arthritis. The rapid onset and corresponding occasional rapid subsidence of the inflammation suggest that it may be the reaction to a toxemia and not to a bacteremia. 736 THE PRACTICE OF PEDIATRICS The duration of the attack is subject to much variation, it may last but a few days or for six weeks or longer. A case of average severity rarely lasts longer than two or three weeks. There may be no fever, or the temperature may range from 103° to 105° F., depending entirely upon the severity of the infection. Special Manifestations.—Peliosis rheumatica and pleurisy, givmg evidence of an etiology similar to that of acute rheumatism, are con- sidered on p. 742. Erythema nodosum, another manifestation probably of the rheumatic class, is discussed on p. 636. Rheumatic Nodides.—The presence of definite nodules in cases of rheumatism in children is only occasionally noted in this country. In England they are often encountered and were first described by Barlow. John Thomson1 looks upon them as extremely important mani- festations of rheumatism from a diagnostic standpoint and interprets their presence to indicate that the disease is in a serious and progressive form. He has found them present in a considerable proportion of rheumatic subjects, varying from the size of a pinhead to that of a pea or larger. Generally only a few are found at a time, usually over the bony prom- inences of the elbows, knees, and ankles, but occasionally they are present in large numbers, growing not only about all the bony prominences of the limbs, over the vertebral spines and under the scalp, but also on the ribs, clavicles, scapulae, and iliac crest, and over the prominent tendons of the extremities, the fasciae of the erector spinae and abdominal muscles, and even rarely on the rims of the ears. The nodules are never reddish and are not tender. They appear in crops lasting usually a few weeks, sometimes several months, and rarely more than a year. Brenneman,2 in a review of the literature on rheumatic nodules, has affirmed his ability to tell by a glance at the knuckles on which the nodules are apparent: “This child has rheumatism; it is probably active; it is severe; he has an endocarditis.” In our own cases the disease has as- sumed a prolonged course without the acute symptoms of 1 igh fever and extreme pain characteristic of many cases of acute rheumatism, and the existence of endocarditis as a complication has been practically constant. The subcutaneous rheumatic nodule is said to be homologous with those that form on the valves and mural endocardium in acute rheum- atism, and is evidently the product of local rheumatic inflammation. Prognosis.—The prognosis for the immediate attack in articular rheumatism is good. All cases terminate in recovery if there is no heart involvement. When there has been one attack, however, there is great probability of another, and parents should be made to understand this feature of the disease. Precaution.—In every case of joint rheumatism the heart should be examined daily for evidence of endocarditis and pericarditis. Treatment.—General Management.—Rest in bed is an absolute neces- sity even in the milder cases. The diet of the patient may consist of milk, junket, gruel, toast, stale bread, weak tea, stewed fruit, and orange juice. Vichy and lemonade may also be given. There should be one evacuation of the bowels daily. 1 Clinical Study of Sick Children, 1921. 2 Amer. Jour. Dis. Child., September, 1919. RHEUMATIC FEVER (ACUTE RHEUMATISM) 737 Local Measures.—Considerable comfort may be furnished by local measures, which will permit the child to sleep, resulting in a much im- proved food capacity. The affected joint or joints should be comfort- ably supported on a cushion or pillow, and the parts kept well protected by cotton-wool or flannel dressings. The U. S. P. lead-and-opium solu- tion, if used to moisten the gauze dressings, will aid in relieving the pain. The joint should be loosely wrapped in strips of linen which have been wet with the warm solution. Over this should be placed oiled silk to prevent rapid evaporation, and over all a flannel bandage. In the acute cases the dressing should be changed every hour until the pain is relieved. This can readily be done without disturbing the patient. A liniment composed of menthol, 2 drams, tincture of opium, ounces, and enough alcohol to make 6 ounces, applied on strips of linen and covered with oiled silk, is another local application which has been of considerable service in relieving pain. This dressing should be renewed every two or three hours as the case requires. Drugs.—Various drugs, such as oil of wintergreen, aspirin, and com- binations of the alkalies with the salicylates, have been used in a consid- erable number of cases. The most effective internal medication has been the bicarbonate in association with the salicylate of soda. The salicylate must be given in large doses. Two points, however, are to be kept in mind in the administration of large doses of salicylate to chil- dren: its depressing effect upon the heart, and the tendency to produce derangement of digestion, as evidenced by nausea and vomiting. The salicylate should never be given with the stomach empty. It is given to the best advantage after meals, and always in solution. For a child five years of age the following may be prescribed: 1$. Sodii salicylatis 5ij Elix. simplicis giss Aquae q. s. ad. 5iv Sig.—One teaspoonful in plain water or in Vichy four times daily after meals. There are about 24 teaspocnfuls in a 4-ounce bottle. The average tea- spoonful, as is well known, holds more than 1 dram. Computing 24 doses to a 4-ounce mixture, we give this five-year-old patient 20 grains of salicylate of soda in twenty-four hours. The amount may be increased to 60 grains if the condition is serious. larger doses than 60 grains for children of this age we consider not always safe, as such doses have been followed by irregularity of the heart action and cyanosis. The average child from eight to ten years of age will take 60 grains daily without inconvenience. At the third year 20 to 30 grains daily have been given repeatedly, with most satisfactory results. The bicarbonate of soda may be given in combination with the salicylate, but it is best given alone in Vichy or carbonic water between meals. To a child five years old or under, 60 grains should be given in twenty-four hours. For chil- dren from seven to ten years of age 60 to 100 grains daily is the amount required. The dosage, both of the salicylate and of the bicarbonate of soda, should gradually be reduced as the condition of the child improves. The Rectal Administration of Sodium Salicylate.—In not a few chil- 738 THE PRACTICE OF PEDIATRICS dren the stomach develops an intolerance of sodium salicylate, give it as we may. In such cases in order to secure respite for the stomach the drug may be given satisfactorily by the rectum. Twenty grains of the salicylate of soda is added to 3 ounces of mucilage of acacia and intro- duced by means of a No. 14 American catheter and a large bulb syringe, the catheter being inserted at least 8 inches into the bowel. The solution should be warm. It will be better retained if the child maintains a position on the left side for an hour after the injection. This dose should be repeated daily. Later Treatment.—It is incumbent upon the physician never, willingly, to let a child who has had an attack of acute articular rheumatism dis- appear from observation. As the outcome of repeated attacks, endocar- ditis is likely to develop sooner or later. After one attack the parents should be advised as to the probability of a recurrence and its dangers. Five days out of every fifteen 10 grains of the salicylate of soda, sepa- rately or combined with 20 grains of bicarbonate, should be given daily. This should be continued for six months, when treatment for five days out of each month will suffice. In some cases this method has been continued for several months. In all cases of acute articular rheumatism in children the tonsils and adenoids should be thoroughly investigated and their removal ad- vised if they are even suspected to be diseased. Foci of infection have also been found at the roots of the teeth. Therefore an x-ray examination of the teeth should always be made with a view to the removal of such foci. THE RHEUMATIC DIATHESIS In a considerable proportion of the population there exist certain physical characteristics which set these individuals apart in a class by themselves. The constitutional condition referred to is well recognized, and various designating terms have been applied to it, such as the rheu- matic diathesis, the rheumatic complex (Still), lithemia (Osier), and lithemic diathesis. The condition is, to be sure, but little understood. Nevertheless, if we admit that rheumatic fever (acute articular rheu- matism) is due to a specific infecting agent, we must also admit that there is a favorable field for activity of this agent in certain members of the human race. Children who have the rheumatic symptom-com- plex as described below are those who most frequently develop acute articular rheumatism and endocarditis. The more prominent features of the rheumatic symptom-complex comprise lack of resistance to infection of the respiratory mucous mem- branes and the tonsils; pronounced lack of nervous balance, manifested by habit spasm; and a tendency to a spasmodic condition of the res- piratory tract, as seen in bronchial spasm and catarrhal laryngitis. An- other peculiarity, as relates to the nervous system, is absence of control during play; the patients become much excited, and waste much energy over trifles. In the consulting-room one sees such children in ceaseless activity, which they apparently cannot control. They are very apt to lack concentration. They have frequent “growing pains” and suffer from periodic stomach and intestinal crises. They are, furthermore, THE RHEUMATIC DIATHESIS 739 subject to eczema and urticaria. Children of this type are the offspring of those who have been similarly affected, or who have what they have learned to designate as rheumatism, lithemia, gout, or the uric-acid diathesis. Often in the offspring of these individuals will be found a combina- tion of the above tendencies; the association of eczema, spasmodic bron- chitis, catarrhal laryngitis, and frequent rhinitis; of growing pains, chorea, and endocardial rheumatism; or of cyclic vomiting and acute bronchitis. Illustrative Case.—In two brothers, who had cyclic vomiting, there was invariably an attack of tonsillitis first and then the vomiting, which was in turn followed by asth- matic bronchitis. None of the attacks were very severe, but each time the same sequence was carried out. The above associations have been remarked in too many cases to ascribe them to a coincidence. Further, it is the child of this type who develops articular rheumatism and endocarditis. Etiology.—The chemicophysiologic defect appears to be in the nature of defective oxidation. At any rate, the more apparent bodily functions are not appreciably involved. The age incidence is of interest. Infants who suffer from eczema, who are susceptible to bronchitis, and in whom it is of the spasmodic type, often show the rheumatic tendencies later in life. The more active manifestations, however, do not appear until the child has passed the period of infancy.1 Treatment.—It is obvious that children of the type described show not only a particular predisposition to certain affections but also decided lack of resistance to the particular form of infection which occasions acute rheumatism. The prevention of cyclic vomiting, recurrent spasmodic bronchitis, chorea, and the other conditions referred to depends upon a proper management of the so-called vice of constitution. Growing pains, habit spasm, tendency to recurrence of eczema, and the various nervous manifestations enumerated may be controlled largely through proper treatment of the “rheumatic complex.” The first and most important step in the treatment relates to diet.. Diet.—Children conforming to this class have a poor fat and sugar capacity, particularly for cane-sugar and cow’s milk fat. The nearer the approach to a vegetable and cereal diet, the better for the patient. The nitrogenous foods allowed are poultry, fish, and egg-whites. Sugar is not to be permitted. Vegetables, stewed fruits, and skimmed milk puddings may be freely used. Skimmed milk or buttermilk may be given with the morning and evening meal. All cereals are permissible. There is no trouble in establishing a well-balanced ration. Children will readily learn to do without sugar. There is little or no trouble in feed- ing cereals without sugar. With stewed fruits and puddings, saccharin may be used in small amounts. Many children take stewed fruits, cereals, 1 These observations and conclusions have been made in private practice. The hospital does not furnish an opportunity for observations on a child, carried through several years, as is necessary in order to know the patient from every standpoint. Those who have not had a large private work with children for a considerable period, or who have not carefully watched their patients, will not appreciate the conclusions expressed. 740 THE PRACTICE OF PEDIATRICS and puddings without a particle of a sweetening agent. Puddings and junket are to be made with skimmed milk. The fat in the egg yolk is particularly toxic to some of these children, particularly those who have cyclic vomiting. Egg yolks are accordingly not to be used in puddings. When one whole egg would ordinarily be used, the whites of two eggs may be used instead. A custard may thus be made as follows: White of one egg. Saccharin. I cup scalded skimmed milk. 10 drops of vanilla. 10 grains salt. Stir white of egg with silver fork. Add milk gradually, salt, and flavoring. Strain and bake somewhat longer than for ordinary custard. In many instances rheumatic children suffering from some one or more of the above-mentioned conditions, together with anemia and a stationary weight, coated tongue, and loss of appetite, have made aston- ishing gain without other treatment when the sugar and cow’s milk fat were removed from the diet. Three meals a day should be given. A free daily bowel evacuation is to be insured (pp. 273-276). If there is malnutrition, the scheme of living, as suggested in tardy malnutrition, is indicated (p. 147). The Bath.—The child should be given a bath at bedtime, followed by a cold splash or douche. After the bath, while the feet remain in the warm water, a quart or two of cold water should be thrown over the body. The degree of cold may vary— 80° to 70° F. at first; after a week or two water as it runs from the faucet may be used if the child enjoys it, regardless of tTe season. After the cool douche the patient should be vigorously rubbed with a bath towel and put to bed. Drug Treatment.—The only drug necessary, other than perhaps an appetizer or a laxative, is bicarbonate of soda, which should be given in interrupted dosage—from 15 to 30 grains, three times daily, depend- ing upon the age and requirement. The soda is best given after meals for ten days, with a free interval for five or ten days, when it may be re- sumed. After a period of a few weeks the soda may be discontinued, but the diet must be kept up indefinitely. Lithemic children cannot bear alcohol, and it should not be included in their tonic or restorative medication. When there is a high degree of systemic poisoning which resists the above measures, sodium salicyl- ate in dosage of rarely more than 5 grains should be given three times a day, after the interval method, in conjunction with the bicarbonate of soda. All the measures suggested, without the withdrawal of sugar and fat largely from the diet, are of little avail. Illustrative Cases.—Case 1.—A case which is characteristic of many was that of a two-and-a-half-year-old scion of one of America’s most noted families. When the boy came under treatment he was having periodic attacks of catarrhal colds, associated with cyclic vomiting. The attacks would last for two or three days and were not very severe, rarely being accompanied by fever. He had been treated for these repeated colds by different physicians with expectorant drugs and local chest applications, all of which, as might be expected, were without effect. He was given the dietetic and drug management, as indicated above; and notwithstanding the fact that there had been attacks every fourteen days, there was but one attack in the two years under treatment. First cousins of this child had habitual colds with spasmodic bronchitis. THE RHEUMATIC DIATHESIS 741 Case 2.—A most remarkable case was that of a girl who came under treatment in early infancy for an intense and obstinate eczema. From this she recovered, and when one year of age developed cyclic vomiting. During the next two years there were frequent attacks of cyclic vomiting, spasmodic laryngitis, and bronchial asthma. The association of these conditions has been previously referred to. Recurrent Bronchitis.—Asthmatic bronchitis is often dependent upon the rheumatic state, and repeated attacks suggest the degree of the vice of constitution. Illustrative Cases.—Case 1.—A girl eight years old had suffered from repeated attacks of bronchitis. The mother, a woman of unusual education and refinement, stated that the child had had an average of two attacks monthly during the previous year, and at least one attack every month since she was five years of age. On meeting the expression of some doubt as to the frequency, the mother stoutly maintained that her statement was correct. The family lived in Brooklyn, and had been told that the child could not remain there during any portion of the year. She had spent the colder months at different winter resorts, with very little, if any, resultant effect upon the severity or frequency of the attacks. There had been no other illness of conse- quence. The attacks were peculiar in that they were of short duration, but very severe. There was usually a temperature range from 100° to 101° F., associated with cough, difficulty in breathing, and occasional attacks of marked air-hunger. The attacks were always accompanied by severe coryza. The patient was seen at the end of an attack. She was pale and inclined to be overstout. An examination of the chest showed through- out a fairly even distribution of mucous rales involving the smaller tubes. Aside from the bronchitis and secondary anemia the examination was negative. The child had attended school at irregular intervals, but only for a few weeks of her life. In getting the history inquiry was made, as a matter of routine, if the child snored or if she were a mouth-breather. This caused the mother to remark that the child had been under the care of throat specialists at different times, and each physician had removed a set of tonsils and a set of adenoids! The mother did not think that there was very much left. There was no sign of a tonsil and the nasopharynx was free. In spite of a normal rhinopharynx, the colds had continued. The family was rheumatic on both sides for at least three generations. The mother claimed to have suffered a great deal from rheumatism. The child was fond of red meat and, according to the mother, lived on it, and cared for little else, with the exception of sugar. Here was a girl, eight years of age, who would not drink milk until sugar had been added to it. Cereals, stewed and raw fruits were loaded down with sugar before she would touch them. In the instructions as to the treatment, red meat was allowed once every second day and sugar was reduced to a minimum—probably not more than one-fifth the usual amount being given. The child was to be bribed, if necessary, to eat green vegetables, cereals, and fruits. Expectorant and cough mixtures were discontinued. She was given 20 grains of the bicarbonate of soda and 20 grains of the salicylate of soda daily for three weeks. Later the drug treatment was continued at intervals during the remainder of the winter. She passed through the following winter without a sign of rhinitis, bronchitis, or asthma, although she continued to live in Brooklyn. Case 2.—Another case somewhat similar was referred by a well-known rhinologist. The patient, a girl seven years old, had suffered from repeated attacks of bronchitis and asthma and had been confined to her home a greater part of each winter. Her general condition was thoroughly wretched. Her family physician had attributed the condition to enlarged tonsils and adenoids, and the child had been sent to New York for operation. The operation was performed, and the child returned to her home. As a result the patient could breathe easier and sleep better, and suffered much less during her attacks of asthmatic bronchitis; but the frequency of the attacks was in no way affected. Early the following summer the patient was again taken to the rhin- ologist, who, finding the condition of the upper respiratory tract satisfactory, referred the patient for medical supervision, remarking that he had “cut everything in sight and out of sight!” The treatment outlined was instituted, and while the results were not so flattering as in Case 1, the condition was much improved; only three attacks occurred during the next twelve months, and the child gained 15 pounds in weight. Repeated inflammatory involvement of the mucous membrane of the upper respiratory tract in children, particularly in the absence of enlarged tonsils and adenoids, strongly suggests a rheumatic element as a prom- inent causative factor. 742 THE PRACTICE OF PEDIATRICS There are other conditions, apparently of rheumatic origin, which are not infrequently associated with the common manifestations. Rheumatic Pleurisy.—In four cases thus diagnosed there was no pneu- monia and no lung involvement of any nature. The fluid was sterile, and the patients never, in the years under observation, had further lung signs. The amount of fluid in each case was large. All the patients came for treatment because of interference with respiration. If there had been fever, it had in each instance subsided before the case came under observation. There was no pain and no evidence of discomfort other than the cyanosis caused by pressure. In two of the cases there was a distinct history of rheumatism. These children were between two and six years of age. Treatment.—The diet was given as outlined, with salicylate and bi- carbonate of soda in dosage suitable for the age. In all the cases there was a complete absorption of the fluid in less than a week. Peliosis Rheumatica.—In this unusual affection, which appears to be of rheumatic origin, purpura is a prominent symptom. In our patients the purpuric area has always involved the anterior portion of the lower extremities, and in every instance the disease has occurred in a patient who had had previous attacks of rheumatism or chorea, or in whom the rheumatic element was prominent, as shown by recurrent tonsillitis or recurrent bronchitis. A further proof of the rheumatic origin of the disease is the fact that the cases may yield readily to treatment for rheu- matism. Treatment.—In one patient there were two distinct attacks, both of which yielded fairly well to the salicylate of soda and the iodid of potas- sium. The medication and diet are the same as those suggested for rheumatism. In case erythema nodosum accompanies the condition, local measures for the relief of pain (p. 636) may be necessary. RHEUMATOID ARTHRITIS; ARTHRITIS DEFORMANS; STILL’S DISEASE Under the above headings may be noted those forms of chronic ar- thritis which occur independently of ordinary pyogenic infection, gonor- rhea, syphilis, tuberculosis, rheumatism, and rachitis. Attempts at exact differentiation of the arthritides of this class rest in the main upon varying clinical manifestations which may or may not represent separate and distinct disease processes. Rachford1 has emphasized three types of “rheumatoid arthritis”— (1) Chronic arthritis with hypertrophic changes predominant; (2) chronic arthritis with atrophy predominant; (3) Still’s disease. The condition last named is sufficiently striking to require special attention, and the points emphasized by Still are here mentioned. Still’s Disease.—The specific etiology is unknown. The disease is probably of bacterial origin. Females are apparently slightly predis- posed. Children are rarely susceptible after the sixth year. The morbid anatomic changes comprise thickening and vasculariza- tion of synovial membranes, capsules, and ligaments of the affected joints, and, in advanced cases, moderate atrophic changes in the carti- 1 Diseases of Children. SYPHILIS 743 lage, with perhaps the formation of adhesions. Effusion is not an es- sential part of the process. Considerable enlargement of the lymphatic glands and spleen is a constant feature. Symptoms.—The onset is usually gradual, but may be acute, with fever and chills. Primary stiffness in one or more joints is succeeded by progressive joint enlargement without bony involvement, ankylosis, or suppuration. The knees, wrists, cervical spine, fingers, ankles, and toes may be affected. Active and passive movements are restricted, and eventually atrophy and contracture of muscles may occur, without, however, impairment of electric reactions. The lymphatic glands are enlarged, particularly those related to the affected joints. The edge of the spleen may usually be found below the costal margin. The blood shows a moderate anemia and occasionally a leukocytosis. Still’s disease is to be distinguished from rheumatism, rickets, syphilis, the various forms of muscular atrophy, and caries of the cervical verte- brae. The prognosis is not favorable. The disease is not directly fatal, but its effects are crippling. Koplik has reported a recovery. The treatment of rheumatoid arthritis is largely symptomatic. An even climate, free from excess of moisture, is desirable. Anemia and malnutrition are to be combated in the usual manner. Massage and suitable applications may influence the local conditions favorably. In view of the possible influence of latent foci of infection upon the develop- ment of the disease, oral sepsis and intestinal putrefaction, especially, must be prevented. Vaccine treatment is of possible value in cases in which the patient’s serum shows reaction against specific organisms, e. g., one or more strains of streptococcus. To this end joint fluid should be cultured. SYPHILIS Syphilis is an infectious, communicable disease seen with great fre- quency in early life in all large centers of population. Bacteriology.—In 1905 Schaudinn and Hoffmann discovered a spiro- chete in syphilitic lesions. From its faint staining reaction they named the organism Spirochaeta pallida, and later Treponema pallidum. It is present in syphilitic lesions on the skin and mucous membrane, and has been found in the blood, in the internal organs, in the lymph-nodes, in spermatozoa, in ova, and in cerebrospinal fluid of syphilitic patients. The tissues and organs of still-born syphilitic infants contain the spiro- chete, and in congenitally syphilitic children the organism is readily demonstrable in the mucous patches in the mouth, in the fissures about the mouth and anus, and in the skin lesions. The older the lesion, the less numerous are the spirochetes. Noguchi was the first investigator who succeeded in obtaining pure cultures of Treponema pallidum, and by inoculating such pure strains into rabbits he produced syphilis in these animals. The spirochete is mobile, varying in length and thickness, its average transverse diameter being 0.2 to 0.3 micron. It is best seen in the fresh state, with the dark field illumination. A rough but fairly reliable method of demonstrating the spirochete is to mix the material to be examined 744 THE PRACTICE OF PEDIATRICS on a slide with a drop of India ink. By means of a piece of cigarette paper the mixture is easily spread evenly along the slide. Examination with the immersion lens shows the unstained spirochetes on a black back- ground. Types.—The disease in children is usually due to direct inheritance, although acquired cases are occasionally encountered. We have, accord- ingly, to consider both the hereditary and the acquired types. For convenience of description hereditary cases are discussed under two headings: Acute hereditary or congenital and late or tardy syphilis. Acute Hereditary or Congenital Syphilis The severity of the infection in the offspring bears a distinct rela- tionship to the severity and duration of the infection in the parent or parents. As in all infections, the disease may be most severe, or mild to such a degree that its existence is not recognized. A recent infec- tion in either parent, or in both, produces the most active manifesta- tions, many times sufficient to destroy the life of the fetus or even to preclude pregnancy. Death of the fetus, showing marked syphilis, any time before the ninth month indicates a comparatively recent infection in the parents. It is the parents in whom the disease is of long duration or who have undergone active treatment who are responsible for the tardy hereditary form. Symptoms.—The symptoms, which are most variable, depend upon the age of the patient and the severity of the infection. Thus the child may be born dead at term, perhaps almost denuded of skin and showing bone and extensive visceral lesions. In other instances the child is born at term, alive, but shows syph- ilitic pemphigus and other lesions, and lives but a few hours. Other infants are born apparently normal and show signs of the disease be- fore the sixth week. Symptoms are very apt to appear between the second and fourth weeks. Seventy-five per cent, of the senior author’s cases have shown diagnostic signs before the fourth month. Some cases do not show signs until a later period—the sixth, seventh, or eighth month. Such cases, however, are unusual. The great majority show some active evidence of the disease before the sixth month. The first manifestation in congenital syphilis may, nevertheless, appear at any time up to the thirtieth year (Fournier). In infants apparently normal at birth and developing the signs early the symptoms are as follows: (1) Restlessness. (2) Rhinitis; hoarse voice. (3) Enlarged liver and spleen. (4) Rash; condylomata; mucous patches. (5) Enlargement of epitroclilear glands. (6) Deformities of the nails. (7) Defective growth and malnutrition. Restlessness is the earliest symptom of syphilis. The child sleeps poorly and is uncomfortable. This symptom is many times not appre- ciated by the physician and usually passes unrecognized by the parents. The restlessness is usually attributed to causes other than syphilis. ACUTE HEREDITARY OR CONGENITAL SYPHILIS 745 Rhinitis is a very early symptom that is seldom absent. It is char- acterized particularly by its persistence and the profuseness of the dis- charge; in other respects it may not vary from an ordinary rhinitis. Fig. 124.—Rash in congenital syphilis. In a considerable proportion of these cases there is a moderate de- gree of laryngitis with hoarseness. This may be the earliest and most prominent symptom. Liver and Spleen.—An enlargement of the liver and spleen is an early sign in most cases. The spleen is ordinarily palpable below the ribs for Fig. 125.—Condylomata. \ inch to 2 inches. The liver also shows enlargement, often extending 2 to 3 inches below the free border of the rib. The rash may appear very early or may be delayed for a week or longer after the rhinitis. The rash is fairly characteristic. It appears in dis- crete, brownish-colored macules (Fig. 124), rounded and with a tendency 746 THE PRACTICE OF PEDIATRICS to a very fine desquamation in the center. The skin between the macules may remain normal. The macules may occur in groups and become so extensive as to coalesce and involve a large part of the skin surface of the patient (Fig. 126). . The moist parts about the buttocks, legs, and over the abdomen are usually involved first and most extensively. There is no order, however, as to the appearance of the rash. The face and arms may be first affected, or the rash may be generally distributed over the entire skin surface. When the rash fades, the skin becomes smooth, but there is left a copper-colored stain which is as characteristic of the disease as the rash. When the eruption occurs about the anus or the moist parts, as in flexures and skin folds, the eruption sloughs and condylo- mata are formed (Fig. 125). In many cases, particularly in very young infants, a diffuse thicken- ing of the skin of the soles of the feet and palms of the hands occurs with profuse desquamation (Fig. 128), leaving the skin of a glossy, shining Fig. 126.—Extensive syphilitic rash. Fig. 127.—Fissures and mucous patches. appearance. How long the skin eruption would continue, untreated, if the patient survived is difficult to determine. Under suitable medi- cation the eruption largely disappears in two to four weeks, leaving the copper-colored disfigurations, which in turn fade, but require a much longer time (Fig. 126). ACUTE HEREDITARY OR CONGENITAL SYPHILIS 747 Fissures at the angles of the mouth and on the lip, and mucous patches (Fig. 127) are really a part of the skin manifestations—they are character- Fig. 128.—Desquamation.

Such lesions A B Fig. 129.—Syphilitic lesions in tibia* of a young infant. are usually found on the mucous membrane of the mouth. Other possible sites are the anus and the female genitals. 748 THE PRACTICE OF PEDIATRICS Acute epiphysitis occurs in young infants, but in this country it is an unusual manifestation of syphilis. There is swelling of the epiph- yseal cartilages and there may be separation of the epiphysis. The parts are very painful, giving rise to the term “syphilitic pseudoparalysis.” The nails are dwarfed, dry, and break readily. There may be ex- foliation of the nail, but this is unusual in infants. A characteristic defor- mity is the bird-claw nail, in which the nail is much contracted, showing an arching of the dorsum of the nail with a thickening, and a down- ward curve at the free end, over the tip of the finger or toe, producing a typical claw appearance. This is a sign of much diagnostic value. Hemorrhages in congenital syphilis are rare. They may occur from any mucous surface. In a large number of cases of congenital syphilis seen in this country and on the continent there were but 2 in which hemorrhage was a symptom. In both these cases, strange to say, there was quite severe hemorrhage from the vagina. The Wassermann Test.—This is positive in a very large percentage of cases, but is subject to variation dependent on such factors as age of the patient, previous treatment, and dura- tion and severity of the infection. (See pp. 826- 827.) A negative Wassermann test in the first months of life does not exclude the possibility of congenital syphilis. Treatment.—Mercurial Inunction.—Formerly the only means of treating congenital syphilis in infants was by the use of mercury, either locally, as by inunctions, or by internal admin- istration. The use of mercurial ointment by inunction is a satisfactory method in hospitals and in children’s institutions, where a nurse can make the necessary applications; in private practice, however, it is objectionable because of the inunction itself, which may cause comment, and because of the staining of the skin. In fact, this treatment cannot well be carried on with- out other members of the family becoming ac- quainted with the nature of the illness. Definite rules for management, as regards kissing and the care of feeding utensils, should be given, so that the other members of the family may be protected and the real condition remain unknown. Among the poorer class and in out-patient work the inunction method is usually unsatisfactory, for the additional reason that its use is not continued sufficiently, and it is very apt to be indifferently applied or else postponed and forgotten. If the inunction is employed the mercurial ointment, U. S. P., should be used, 10 grains being rubbed into the skin daily. The rubbing should be continued about ten minutes, as this time will be required for the ointment to be thoroughly absorbed. Fig. 130.—Bones shown in Fig. 129, B. The im- provement took place in a period of five and a half weeks, following daily mercurial inunctions com- bined with four doses of 0.075 to 0.1 gm. of neosal- varsan, and the adminis- tration of cod-liver oil. (From the New York Nur- sery and Child’s Hospital.) ACUTE HEREDITARY OR CONGENITAL SYPHILIS 749 As the disease permits of no temporizing, it is for the interest of the patient that more effective means possible for its control be brought into use at the earliest possible moment; this is by the internal adminis- tration of mercury. The Internal Use of Mercury.—The use of mercury internally gives good results among all classes. It is the writer’s observation, after the treatment of several hundred of these cases, that the bichlorid of mer- cury in small, frequently repeated doses is the best form of oral medica- tion. It is given in tablet form. Its use may have to be continued for a long time, and, as people are fond of giving drugs, we cater to the weak side of human nature, and thus do the greatest good to our patient. For all infants under one year of age the scheme of medication is the same, and this covers the great majority of our cases. Usually the patient is seen before the third month. In this event the tablet triturate of bi- chlorid of mercury, 1/200 grain, is prescribed. The mother is instructed to give 2 tablets daily, morning and night, after feeding. She is told to give on alternate days an additional tablet after feeding, until 5 are given daily, or until the mercury produces loose green stools. It is compar- atively rare that an infant of the ten derest age cannot take 1/40 grain daily without inconvenience. If green stools of a watery character result, the increase is temporarily withheld. It is very rare that the above amount will not ultimately be taken without inconvenience. Further, the dosage of 1/40 to 1/30 grain in twenty-four hours, in the great majority of the cases, is all that is necessary to control the disease. If an improvement does not take place after a week’s administration, in the absence of intes- tinal symptoms, the amount may be increased to 1/20 grain in twenty- four hours. If, after the administration four or five times daily of the bichlorid in the small doses of 1/200 grain has been continued for several days, im- provement does not take place because of failure on the part of the child to absorb the drug, inunctions may be used in addition to the internal treatment. Arsenicals in the Treatment.—The greatest value of the arsenicals is in the very severe congenital case. Repeatedly such infants die before the effects of mercury are manifested. The arsenicals act much more rap- idly than mercury. In fact, the results of salvarsan treatment on the very severe congenital syphilitic border on the miraculous. The chief value of salvarsan in pediatric work is, however, in cases of this type. For permanent, beneficial effects we are still dependent upon mercury and the iodids. For babies under six months the average dose of neosalvarsan is 0.075 to 0.2 gm., and for older children 0.2 to 0.4 gm. Salvarsan is used in doses one-half as large. The consensus of opinion now seems to be that the arsenical should be given at weekly intervals until the gross lesions have cleared up. This treatment is always followed by the use of mercury. The arsenicals alone do not effect a cure. The Combined Treatment With Mercury and Neosalvarsan.—A practical method of treatment for young children, devised by Fordyce and Rosen, is the intramuscular injection of mercuric chlorid put up in palmitin in individual collapsible ampules. The dosage is 1/10 to 1/8 grain or larger 750 THE PRACTICE OF PEDIATRICS for older children, and the injections are given at intervals of a week for about eight doses. Then weekly intramuscular injections of neosalvarsan in doses of from 0.075 to 0.2 gm., depending upon the size of the child, are begun and continued for about eight doses. The patient is then allowed a month’s rest and the cycle again begun. The Wassermann is taken at this time. This course is repeated indefinitely regardless of the change in the serum reaction or clinical signs. In injecting both the mer- cury and the arsenical the Rosen needle is used. This is an ordinary 19 or 20 gage needle, from \ to 1 inch long, with a curved phlange at the shank of the needle which fits snugly over the curve of the buttocks and prevents movement of the needle even when the child is squirming. The injection is made into the gluteus about 1 inch lateral to the intergluteal fold near its upper angle. Infiltration or abscess at the site of puncture may be avoided by injection deep into the muscles and rapid withdrawal of the needle upon completion, thus preventing the seepage of the drug into the subcutaneous tissues. Treatment should extend over a period of at least a year regardless of results. The question of the permanent cure of congenital syphilis is still debatable. Convalescence.—In a typical case the first sign that the child is im- proving will be the fading of the rash. It disappears gradually, leaving the characteristic staining of the skin, which also clears up in a few weeks. Coincident with the fading of the rash the coryza becomes less pronounced and the hoarse voice becomes clearer. If there has been an enlargement of the liver and spleen, after a few weeks of treatment they will have diminished in size. The child gains in weight, and if the case progresses satisfactorily, soon looks like a normal baby. This, however, is not al- ways the happy outcome. Occasionally we have patients with the vital powers greatly depressed or with so intense an infection that treatment is of no avail, and they die in a few weeks from marasmus. The enlargement of the epitrochlear glands is a late sign to disappear, and in many cases these glands, though reduced in size, always remain enlarged without any other persistent evidence of the disease. A patient is considered cured who fails to give a positive reaction to repeated Wasser- mann tests of the blood. Later Treatment.—What should be the further management of such a so-called “cured” case? Are we justified in discharging the patient and allowing him to pass from our observation? Experience proves the contrary, nor can we positively state that congenital syphilis is ever cured. We have seen many patients, however, who were apparently cured, and who showed no signs whatsoever of the disease. Against advice they have passed from observation for two, three, or four years, and then have reappeared for treatment because of the presentation of some manifestation of a tertiary character—a so-called “tardy hereditary syphilis.” For this reason we believe every so-called cured congenital case should be subjected to the Wassermann test every two years or oftener. Acquired Syphilis Acquired syphilis in children is a comparatively rare occurrence. The mouth is the most frequent site for the primary lesion, the genitals being rarely involved. Infection may be conveyed by direct contact, TARDY HEREDITARY SYPHILIS 751 as in kissing or by sexual contact. The virus may be conveyed by inter- mediaries, such as toys, nipples, and feeding utensils. The recital of statistics and special modes of infection adds nothing to our knowledge of the subject. It is necessary to remember that a localized lesion, slightly sloughing over its surface, indurated and sharply defined, may be in a child the initial lesion of syphilis. The treatment is the same as that of the hereditary form. Tardy Hereditary Syphilis In this form of syphilis the chief or only manifestation of the disease occurs at a later period of life. Fournier has stated that the first signs of the disease may appear as late as the thirtieth year. Whether the case in which positive signs are not observed until after the thirtieth year did not show unrecognized signs early in life is an open question. Most observers are convinced that an individual may show signs of syphilis at varying periods after infancy without early signs of the disease. Several years ago the senior author reported 6 cases of tardy malnutrition of syphilitic origin in which there had been no early signs of the disease. Since that time he has seen several other cases of a similar nature. The great majority of patients with tardy hereditary syphilis, however, are those who were treated in infancy in out-patient clinics or elsewhere and whose treatment was discontinued when the active symptoms were relieved. Many mothers cannot be made to bring their children for treat- ment and observation when they are apparently well. Pathology.—Eye.—The eye changes are those of an interstitial kera- titis, gummatous involvement of the iris, and the so-called deep inflam- mations of the eye, chorioretinitis and optic neuritis. Ear.—Progressive deafness due to neuritis acustica (Meniere’s disease) is typical. Skin.—According to Hochsinger, the changes in the skin do not differ from the tertiary skin lesions of acquired syphilis. He described two forms, small nodules, and laige nodular late syphilids. The small nodules are due to a definite infiltration of the true skin, which presents a brownish appearance and may desquamate or become covered with a heavy crust. Beneath the crusts there is usually broken-down granidar tissue. The large nodular syphilid occurs in the form of large skin gummata and gummatous ulcers arising from the subcutaneous tissues. Mucous Membrane of the Respiratory Tract— This structure may become invaded in a specific manner. It may be the seat of gumma- tous infiltrations or a rapidly progressive ulceration. Ulcerations of the pharynx and larynx are not rare. Such lesions are usually character- ized by definitely defined borders and thick indurated walls. In the nose there may be a diffuse osseous and periosteal affection of the entire nasal skeleton, or a gummatous change may represent the primary path- ologic process, followed by ulceration with much pus and crust formation. On the contrary, there may occur an atrophic condition of the mucous membrane. Levin and Heller have described a smooth atrophy of the base of the tongue characterized by absence of glandular tissue and thinness of the mucous membrane. Gummatous formation, as described above, 752 THE PRACTICE OF PEDIATRICS may occur on the velum palati, palatine arches, and uvula, with per- foration. All the ulcerations show a great tendency to scar formation, with corresponding contractions and adhesions to adjacent parts. Lymph-nodes.—A general hyperplasia of the lymphatic tissue of the pharynx and nasopharynx, including the tonsils, may take place, while in the lymph-nodes throughout the body, aside from general hy- perplasia, gummatous formation is not uncommon. Occasionally the glands may undergo ulceration. Vessels.—There may exist, according to Hochsinger, a gummatous aortitis, arteriosclerosis, and phlebosclerosis, while myocardial and endo- cardial changes have been observed. Viscera.—Liver affections deserve the first rank. There may exist large nodular gummata; the diffuse hypertrophic cirrhosis is most com- mon. These changes are almost always associated with more or less Fig. 131.—Showing saber deformity of legs in tertiary congenital syphilis in a child nine years of age (Dr. Sill). splenic hypertrophy. The kidneys may be small and contracted; amy- loid degeneration is rare. Gummatous formation in the lungs may occur, but is very uncommon. Bones.—Late syphilitic changes occur in the osseous system either as a diffuse hyperplastic osteitis and periostitis, or as a gummatous process. Lesions of both varieties, however, may occur at the same time in the same individual. According to Lannelongue, a hyperplastic osteitis and periostitis may involve the whole skeleton. The long bones are chiefly affected. The same author has considered that the so-called Paget’s bone disease, which is a diffuse progressive periostitis leading to hyper- ostosis, is nothing more nor less than hereditary syphilis. The tibia is the bone most frequently involved. The disease here produces what is known as the "saber deformity.” (See Fig. 131.) Fol- lowing the hyperplastic stage is the real stage of hyperostosis, the de- TARDY HEREDITARY SYPHILIS 753 formity being due to the continuous formation of new periosteal bone layers about the primary one. Among the less frequent bone changes in late hereditary syphilis is a rarefying periostitis leading to bone absorption. This condition is seen on the surface of the cranial bones and causes the formation of rough areas (caries sicca). Joint affection in late hereditary syphilis may take the form of a simple hydrops without capsular thickening or a hyperplastic synovitis. Again, there may be a combination of hydrarthrosis, with swelling of the joint-ends of the hollow bones, and in rare instances a condition resembling white swelling. Symptoms.—This form of syphilis in the young may manifest itself in widely different ways. Errors in Nutrition (see p. 755).—A not infrequent manifestation is that of moderate malnutrition and stunted growth. The patient is habitually pale, undersized, and shows lack of resistance, such evidences perhaps constituting the only signs of the disease. Fig. 132.—Hutchinson teeth. The Bones.—Characteristic signs are to be found in the bones and teeth. The shafts of the long bones are involved in a periostitis. (See Fig. 131.) The tibia when affected may show the saber deformity. The tibia is most frequently involved; next in frequency, the radius. Gum- mata may involve the flat bones of the cranium, although such an occur- rence is comparatively rare. The “saddle nose” caused by a destruction of the septum is a condition not infrequently seen in congenital syphilis. The Teeth.—Fairly characteristic signs, first described by Hutchin- son, are often shown by the second set of teeth. The first set in no way give evidence of the disease. Hutchinson’s teeth represent faulty de- velopment. They are variously described, according to the deformity presented, as “notched,” “screw-driver,” and “peg-shaped.” (See Fig. 132.) Lymph-nodes.—The only lymph-node involvement of significance is that of the epitrochlears. General lymph-node involvement is to be looked upon as corroborative of other signs of consequence. 754 THE PRACTICE OF PEDIATRICS The Eye.—A diffuse interstitial keratitis is one of the most frequent manifestations of tardy hereditary syphilis. Involvement of Other Structures and Organs.—The spleen is usually enlarged, the liver not infrequently. Cases of brain tumor of syphilitic origin are occasionally seen. Juvenile tabes and paresis are sufficiently frequent to call for consideration in connection with suggestive neuro- logic signs. In fact, any portion of the body may be involved in a syphil- itic process, and a detailed description of the various possibilities is out of place at this time. Treatment.—Experience with the new arsenical preparations in tardy hereditary syphilis has been thoroughly unsatisfactory. As in the treat- ment of tertiary syphilis in the adult, likewise in the treatment of the late hereditary form in children, the iodids play an important part. Much better results, however, are obtained with the so-called “mixed treat- ment.” The iodids alone are not sufficient to give us our best results, and the results with mercury alone are not so prompt and satisfactory as when the two drugs are combined. For an average case of periostitis involving the anterior portion of the tibia in a child four years of age, from 1/30 to 1/20 grain of bichlorid of mercury should be given daily, combined with sufficient iodid of potash to produce the characteristic coryza. This may necessitate the giving of from 12 to 20 grains of iodid daily, as children vary greatly in their susceptibility to the drug. The mercury and the iodid of potash should not be given in one mixture, as the combination is most disagreeable to the taste. It is far better to give the bichlorid in the form of tablet triturates. The iodid of potash is best given in a saturated solution, 1 drop of which represents 1 grain of the drug. This is best taken when dropped into milk after meals. Ben- eficial results from the treatment will usually be apparent in a few days. If there is a periostitis, the pain will be the first symptom to disappear. The administration of the iodid of potash should always be inter- rupted, chiefly because of the possibilities of deranging the child’s di- gestion. A good rule is to give the drug for ten days, followed by a rest of five days, when it is again resumed. Proper nutrition in these cases is a most important factor in their management. If the iodid is given to the point of tolerance, its omission for a few days will not be noticed. The mercury should be given for weeks continuously in doses of from 1 /60 to 1/20 grain three times a day, graduated according to the age. Later, when the progress of the case shows that the disease is under control, the two drugs should be given alternately, for ten days each. How long this treatment should be continued must be determined by each indi- vidual case. The Wassermann test in these cases is of much service. Patients who are apparently cured should be instructed to report to the physician every three months. A course of treatment for three or four weeks two or three times a year is to be advised. A sufficient excuse for such action may be the condition of the child, who may show a tend- ency toward slow growth and improper nutrition. The patients should be kept under observation for years and should be seen at stated inter- vals until the adult period is reached, when the nature of the trouble should be explained to them. The disease from which such a child is suffering should always be made plain to parents, or at least to one of TARDY MALNUTRITION OF SYPHILITIC ORIGIN 755 them, in order that the patient may not be allowed to pass from under medical observation in ignorance of his true condition. Tardy Malnutrition of Syphilitic Origin The possible manifestations of syphilis in the young, as in the adult, are many. The infection may be so severe as to destroy the fetus, or so mild in its effects as to make recognition difficult. Not the least inter- esting and important of the cases showing remote manifestations are those in which late malnutrition is the only evidence of the syphilitic in- fection. The patients are usually thin, sometimes sallow, sometimes pale, with little or no adipose tissue. They are almost always under normal height, and always underweight; with poor appetite and little endur- ance and correspondingly little resistance. Those seen by the writer have been between three and ten years of age. None were mentally defective. When 2 such children are seen in a family in which both parents are robust, this circumstance is a strong indication that the children are suffering from the results of a remote syphilitic infection in one of the parents. The physical examination may show nothing definite, and yet the Wassermann reaction prove positive. Cases of late malnutrition, non-syphilitic in character, due to poor hygiene and faulty feeding, may present symptoms identical with the above, so that while the two conditions cannot be differentiated by the clinical signs, there may be sufficient grounds for suspicion to warrant us in questioning the father, whereupon the history of a primary sore with perhaps secondary lesions may be elicited. There may have been prolonged treatment, with a subsidence of all the symptoms, and the patient may have been pronounced cured and told that he might safely marry. Many times this story is heard when the evidence of transmis- sion is before the physician in the form of a typical case of congenital syphilis. Treatment of tardy malnutrition of syphilitic origin by the supportive and restorative methods used in the cases of non-syphilitic malnutrition is without avail. (See Tardy Malnutrition, p. 146.) These patients require mercury, either alone or combined with the iodids. To the usual methods of treatment with iron, cod-liver oil, baths, and massage, there will be but little response, but if bichlorid of mercury or the iodid of potash be added, the case will improve. The improvement is slow, to be sure, but it is invariable. The child should be given the advantage of an outdoor life, with free ventilation of the sleeping-room at night. The food should be highly nutritious, containing a large amount of protein. Eggs, meat, milk, and the high-protein cereals, such as oatmeal, are the most valuable. The dried legumes—peas, beans, and lentils—given in the form of purees, are a valuable addition to the diet. Brine baths (p. 843) at bed-time during the entire year, followed by oil inunctions dur- ing the cooler months, are valuable in restoring a vigorous condition. As these children are almost always anemic, it may be well to combine the bichlorid of mercury with nux vomica, iron, and quinin. For a child from five to ten years of age the following prescription has been used with marked benefit: 756 THE PRACTICE OF PEDIATRICS 1$. Hydrargyri bichloridi gr. ss Tinctura; nucis vomicae gtt. xc Extract! ferri pomati gr. x Quininse bisulphatis 5j M. Div. et, ft. capsulae No. xxx. Sig.—One capsule after each meal. This is given for ten days, when the bichlorid of mercury in tablet form, 1/60 grain three times daily after meals, is substituted for ten days. During the ten days when the bichlorid is given alone maltine and cod- liver oil may be given—1 dessertspoonful three times a day after meals. In these cases iodid of potash is not to be given early in the treatment, for the reason that the appetite is usually poor or indifferent, and the administration of the drug at this time might further decrease the desire for food. Syrup of the iodid of iron may be used in doses of 10 to 15 drops, three times daily, if the physician desires to change the form in which the iron is administered. Duration of Treatment.—Prolonged treatment will usually be re- quired. These patients should be kept under close observation for at least two years, or until they arrive at adolescence, when, as has been stated, they should be made acquainted with the nature of the disease. During the entire growing period the administration of mercury during one month out of every three, or possibly every six, depending upon the child’s condition, will insure better growth and a more vigorous develop- ment both physically and mentally. TUBERCULOSIS Tuberculosis is the condition resulting from an invasion of the body by the tubercle bacillus. The subjects of pulmonary tuberculosis and tuberculous cervical adenitis have been discussed in previous sections (pp. 394 and 458). Types of the Infection.—There are two types of the bacillus—the human and the bovine. In 132 cases of children between the ages of five and sixteen years Park and Krumweide1 found the bovine type in 33 cases. In 20 of these there was a tuberculous cervical adenitis, in 7 ab- dominal tuberculosis, and in 3 generalized tuberculosis. Alimentary origin of generalized tuberculosis was apparent in 1, tuberculosis of the bones and joints in 1, and tuberculosis of the tonsil in 1. The percentages of bovine infections were as follows: Pulmonary tuberculosis Children five to sixteen years, per cent. 0 Children under five years, per cent. 0 Tuberculous adenitis (cervical) 37 57 Abdominal tuberculosis .50 68 Generalized tuberculosis 40 26 Tuberculous meningitis, with or without localized lesion 0 0 Tuberculosis of bones and joints 3 0 Of 220 children infected under five years of age, 59 showed the bovine type. Of these, 20 showed tuberculous cervical adenitis; 13, abdominal 1 Park and Krumweide: The Relative Importance of the Bovine and Human Types of Tubercle Bacilli in the Different Forms of Tuberculosis, Research Lab. Dept. Health, New York City, Jour. Med. Research, 1912. TUBERCULOSIS 757 tuberculosis; 10, generalized tuberculosis—alimentary origin; 5, gen- eralized tuberculosis; 8, generalized tuberculosis including meningitis— alimentary origin; 1, generalized tuberculosis including meningitis; 2, tuberculous meningitis. Park and Krumweide concluded as follows: “In children, the bovine type of tubercle bacillus causes a marked percentage of the cases of cer- vical adenitis leading to operation, temporary disablement, discom- fort, and disfigurement. It causes a large percentage of the rarer types of alimentary tuberculosis, requiring operative interference or causing the death of the child directly or as a contributing cause in other diseases. “In young children it becomes a menace to life and causes from to 10 per cent, of the total fatalities from this disease.” The bovine infection is largely limited to children, and the fatal cases are further limited to infants and very young children. A review of the very extensive literature that now exists on this sub- ject leads one to the conclusion that about 20 per cent, of the cases of tuberculosis in children are of bovine origin. (See p. 459.) Avenues of Entrance.—Tubercle bacilli may enter the body by means of the respiratory and alimentary tracts, by means of the genito-urinary system, and through the skin. The two latter are very unusual modes of entrance. The avenue of entrance of the bovine bacillus is the ali- mentary tract—that of the human type, the respiratory tract. In a large majority of our cases the patient had been in association with a tuberculous individual. Illustrative Cases.—Two children, aged six and eight, developed pulmonary tuber- culosis. They were dispensary patients, and lived in a small three-story tenement house. The fact that the 2 cases developed at the same time seemed conclusive evi- dence of a common source of infection. Both the father and the mother were well, and they, with their 2 children, composed the family. Upon further investigation it was found that the janitor of the tenement had advanced pulmonary tuberculosis, and that he was not at all careful where he deposited tuberculous sputum. Aged people with chronic bronchitis are often carriers of the tubercle bacillus, and such persons are the most dangerous. They remain indoors and infect the rooms. Not suspected of being tuberculous, they are care- less, they kiss and fondle, and often assume considerable care of the younger members of the family. Several cases of tuberculous meningitis have been personally traced to such origin. Illustrative Cases.—In a recent case the infection was traced to the grandfather whom the child visited for four weeks. A baby of nine months, an only child, died from tuberculous meningitis. No source of the infection could be discovered until, six months later, the mother de- veloped acute pulmonary tuberculosis of a very active type. She undoubtedly was suffering from latent tuberculosis at the time of the child’s death. The father contracted the disease apparently from his wife, and died in two years. In all these cases there was a decidedly virulent infection. Predisposing Causes.—Among the predisposing causes age is im- portant. The more tender the age, the greater the susceptibility. Any illness which decreases the general resistance or lessens the resistance of the upper air-passages or lungs, predisposes to the disease. Thus we see many cases following measles, whooping-cough, scarlet fever, influenza, and bronchopneumonia. Adenoids and diseased tonsils are 758 THE PRACTICE OF PEDIATRICS eminently predisposing causes, particularly favoring tuberculous cervical adenitis. Heredity is less a factor than is generally supposed. Often what passes for heredity is a direct infection from a tuberculous parent, in whom the disease has remained dormant in the bronchial glands or else- where, and does not develop until a late period. The close housing of children during the colder months is of no little importance as a means of diminishing resistance to tuberculosis. The habit of frequent change of residence is also a source of infection. A family moves into an apartment or tenement with little thought or knowl- edge of the previous occupant, and the owner makes no effort at paint- ing or cleaning for the new tenants, carrying out only such changes as are absolutely necessary. Tuberculosis has been known to develop in children occupying an apartment in which a tuberculous adult had pre- viously been domiciled. Infection may rarely take place through the blood of the mother by way of the placental circulation. Cases have been reported in our country by Jacobi and Wollstein, in which a tuber- culous fetus has been born to a tuberculous mother. Prophylaxis.—The best insurance against tuberculosis is a vigor- ous bodily resistance. At least 85 per cent, of the human race are in- fected some time before the thirtieth year, but, fortunately, the great majority of those infected are able to withstand the invasion. Obser- vation with the von Pirquet test in different countries, covering a large number of children of varying ages, shows that from 40 to 70 per cent, react positively. The results demonstrate that a vast majority of the human race are infected before the fifteenth year. Adenoids and diseased tonsils should be removed from every child who possesses them. Children should be allowed to make complete recoveries from bronchitis, bronchopneumonia, influenza, whooping-cough, measles, etc. A week or longer from school is a matter of no moment in the child’s future from the standpoint of knowledge. Kissing of children on the mouth should be forbidden. This act is a grossly unfair advantage to take of an in- nocent child. Overwork at school, in mines, and in factories predisposes by fostering close associations and diminishing resistance. The reporting of tuberculous cases, and the rigid enforcement of hygienic measures relating to the disposal of tuberculous sputum, would materially lessen the number of cases. Infants and young children up to the fourth year are very suscepti- ble to tuberculosis. During this period the child should have absolutely no association with an active case in an adult or older child. If there is such an association the infant will in all probability develop tuber- culosis. Milk Infection.—The infection of the bovine type is preventable by pasteurizing all milk and butter which is not taken from tested cows proved free from tuberculosis. The nutritive qualities of milk are not harmed by heating, but all children fed on pasteurized milk should be given orange juice. Relative Frequency in Different Sites.—Although the tonsil is looked upon as a portal for the frequent entrance of the disease, this organ has been found tuberculous in comparatively few instances. In 90 per cent, of all cases of tuberculosis lymphadenitis the cervical ABDOMINAL TUBERCULOSIS 759 glands are involved, and chronic inflammation in these glands, when well advanced, is usually aggravated by the presence of infecting or- ganisms of the staphylococcus or streptococcus groups. Still has reported important findings in 216 postmortem examina- tions following fatalities from tuberculosis in children. In 63.8 per cent he traced the incidence of the disease to the lung; in 29.1 per cent, to the intestine; and in 15 of the 216 cases, to the ear. By other authorities the frequency of primary respiratory infection has been estimated at 65 to 70 per cent., and that of an initial intestinal infection at 15 to 30 per cent. Both Still and Carr have reported finding caseation of the mediastinal glands in 81 per cent, of autopsies on tuberculous subjects, while in a proportion ranging approximately from 55 to 60 per cent, the same ob- servers found a similar condition in the mesenteric glands. The medias- tinal glands on the right side are more frequently diseased than those on the left. Nearly 60 per cent, of tuberculous cases have shown invasion of the mesenteric glands; and in 12 of 100 autopsies upon children under two years of age Still found tuberculous peritonitis. Abdominal Tuberculosis (Tuberculosis of the Mesenteric Glands , Tabes Mesenterica) Tuberculosis of the mesenteric glands is not uncommon in the find- ings at autopsy upon young tuberculous subjects. Rarely is the condi- tion sufficiently developed, in this country, to be recognized clinically independent of peritonitis. The senior author’s first postmortem examination upon a child, however, was in a case of this character. The patient was three months old, colored. In 2 other cases autopsy showed uncomplicated tabes mesenterica with no peritonitis. The condition in 3 other cases was diagnosed as true tabes mesenterica. Symptoms.—The symptoms include slow progressive emaciation, slight inconstant elevation of the temperature, distended abdomen, persistent intestinal indigestion, diarrhea, flatulence, and abdominal pain. The pain is colicky in character, and may be very severe and continue over a considerable period. Diagnosis.—A positive diagnosis is to be made upon one’s ability to palpate the enlarged glands. For critical abdominal examination one must often employ light anesthesia, as this renders the examination far more satisfactory. The glands are often best felt in the right or left iliac fossa. The symptoms somewhat resemble those of chronic appendicitis, and a rectal examination may be necessary to determine if there is an enlargement of the appendix or adhesions or infiltration about it. Celiac disease upon superficial examination is readily confused with abdominal tuberculosis. Prognosis.—The prognosis is unfavorable in cases that have devel- oped sufficient signs for a diagnosis. Still, who has had a large experi- ence in abdominal tuberculosis, has stated that we are never sure of the recovery cases. The diseased glands may at any time be the starting- 760 THE PRACTICE OF PEDIATRICS point of a general or localized inflammation, with the output of exten- sive adhesions resulting in a general tuberculous peritonitis or produc- ing local effects interfering seriously with the functions of the intestine. Illustrative Case.—Some years ago the writer performed an autopsy for a colleague on a two-year-old child who had died suddenly with symptoms of acute intestinal obstruction. The child had had abdominal trouble during the second year, and had been seen by different physicians, one of whom made a diagnosis of tabes mesenterica. The patient improved and three months previous to the fatal termination was well, except for obstinate constipation. The postmortem showed a most remarkable picture of enlarged glands matted together by fibrinous exudate, which had been poured into the abdominal cavity and had undergone connective-tissue formation. The descending colon resembled a hollow tube held in position by the surrounding exudate. How the child had lived and had bowel evacuations is difficult of explanation. The obstruction was caused by an angle forming at the point where the free intestine, filled with gas, joined the fixed portion. Treatment.—All measures that will increase the patient’s resistance should be employed. An out-of-door life and the general management advised in treating other forms of tuberculosis (p. 397) should be followed. Still believes that operative measures are of value. He has found that removal of the enlarged glands is to be advised, as thereby eliminating a definite focus of infection. At the same time fibrinous bands causing pain and other symptoms may be broken up. Acute tuberculous invasion of the peritoneum may be found in a few cases of general tuberculosis. It is of no clinical significance, and is briefly referred to below under Pathology. Chronic tuberculous peritonitis is a comparatively infrequent dis- ease in this country. In England and on the Continent many more cases are seen. Still reported 266 fatal cases of tuberculosis in children under twelve years of age, 45 of whom died with tuberculous peritonitis —a percentage of 16.8. Under two years of age this author found 12 cases of tuberculous peritonitis in 100 tuberculous infants. Age.—The great majority of cases occur between the first and third years. Cases developing before the end of the first year are rare. Etiology.—A considerable proportion of the cases are probably due to an extension from infected mesenteric glands. Through the lymph and blood-channels the bacilli may be carried to the peritoneum from any focus. Types of Bacilli.—Park and Krumweide found the bovine form in 20 of 53 cases of tuberculosis between the fifth and sixteenth years. In 35 children under five years the bovine bacillus was present in 20 cases. Pathology.—The course of the inflammation may be acute or chronic, and the changes produced have given rise to a classification of several types of the disease. 1. The simplest lesions consist of scattered grayish miliary tubercles unassociated with the presence of exudate or other evidences of an ad- vanced process. This picture is seen in connection with a general miliary tuberculosis which may have presented no local clinical signs. 2. In a second form of the disease, coexisting with miliary tubercles which are scattered over the peritoneum in great number, there is a marked ascites depending on the predominance of the element of exu- Chronic Tuberculous Peritonitis CHRONIC TUBERCULOUS PERITONITIS 761 dation. The exudate is serous and contains only a moderate amount of fibrin. When the fluid accumulation is large the intestines are floated up and the abdominal cavity is characteristically distended. 3. A third variety of tuberculous peritonitis is predominantly ad- hesive and unaccompanied by the exudation of much fluid. The loops of intestines become closely matted together and the omentum is rolled up in a firm elongated mass. The typical tubercles are present, but have, at many sites, become confluent and been transformed into larger foci, or given way to the development of reparative fibrous tissue. The amount of fluid exudate is small and may be clear or clouded by the admixture of fibrin and flakes of pus. 4. Finally, the lesions may be of a destructive character, consisting of actual ulcerations caused by the disintegration of large caseous foci. In such an event adhesions between intestines, mesentery, and omen- tum are produced which serve to confine collections of pus. These may eventually break forth and discharge externally. Fecal fistulse or ab- scesses between adjacent portions of intestine are not uncommon. Types of Lesions.—The disease is usually divided pathologically into two leading forms—the ascitic and the plastic or fibrous. There are few cases of the fibrous type, however, without fluid in the abdomen, and few ascitic cases in which there is not some fibrous formation. Still found the proportion of the fibrous to the ascitic type 10 to 1. Symptoms.—Suggestive symptoms in all cases are abdominal dis- comfort, pain, and distention from gas or fluid, digestive disturbances, emaciation, and persistence of all symptoms in spite of medication and careful dieting. The Ascitic Type.—In the ascitic form, when the patient first comes under observation, the abdomen usually contains considerable fluid. This increases rapidly and the abdominal wall becomes distended and tense. There may be a temperature of 100° to 102° F. An elevation of the temperature is, however, not invariably present; it is as often absent. There is a secondary anemia, and the child becomes emaciated and tires readily. A differentiation, however, between tuberculous ascites and that due to other causes may not be possible without corroborative evi- dence of tuberculosis elsewhere. Examination of the ascitic fluid even in positive cases does not always show the presence of the tubercle bacilli. Through absorption of the fluid, cases that belong to the ascitic type at first, change to the fibrous. This phenomenon is not at all unusual. The Plastic Type.—In these cases the onset is gradual, the tempera- ture usually is not high—100° to 101° F. There is loss of appetite with emaciation. Intestinal indigestion, evidenced by tympanites and oc- casional diarrhea, is common. There may be constipation alternating with diarrhea, and there is almost always pain. It is the pain that usually attracts the attention of the parents to the child’s condition. The course of this form of the disease is slow and its progress may be interrupted by periods of improvement. Figures 133 and 134 are reproductions of the z-ray plates made from a case in which tuberculous peritonitis was associated with pylorospasm. 762 THE PRACTICE OF PEDIATRICS The case well illustrates how the inflammatory process may lead to symp- toms of mechanical origin. Fig. 134. Figs. 133, 134.—Tuberculous peritonitis associated with pylorospasm (Kerley and Le Wald, Digestive Disturbances in Infants and Young Children). Male, aged four and a half months. Family history negative for tuberculosis. When patient was four days old a right inguinal hernia was noticed. At seven weeks, 30 c.c. of fluid removed from a left hydrocele; three weeks later, 30 c.c. again withdrawn. Suffered from convulsions, regurgitation of food, and constipation. CHRONIC TUBERCULOUS PERITONITIS 763 Roentgen Examination.—One hour after an opaque meal only a trace had gone through the pylorus, suggesting either a pyloric stenosis or a spasm (Fig. 133). The fact that the stomach had almost completely emptied itself in four hours and twenty-five minutes led to diagnosis of spasm which had evidently relaxed after the one-hour plate. Distinct delay in the small intestine which appeared dilated. Five hours after the meal distended loops of ileum were prominently outlined (Fig. 134). Roentgen diagnosis: Tuberculous peritonitis. Delay of the bismuth in the small intestine is very suggestive of tuberculous perit- onitis. This delay is evidently due to adhesions which are almost invariably present. In addition, there is very apt to be pouching of the small intestine for the same reason. Operation.—Free fluid in the peritoneal cavity and numerous tubercles on the perit- oneum. Small intestine adherent to the abdominal wall in a number of places; hence the impossibility of freeing the loops without danger of perforation. Operative diag- nosis: Tuberculous peritonitis. Diagnosis.—It is rare in cases of the fibrous type or in those due to mesenteric lymphadenitis not to find nodules in either of the iliac fossae or the evidence of fibrous bands in the abdomen. The retracted, thick- ened omentum, forming a distinct ridge across the abdomen, is present in many cases. This may be confused with the lower edge of the liver. Careful palpation, however, will demonstrate the band as thick and roughened, and extending well across the abdomen in a downward di- rection toward the left side. A space between the band and the lower edge of the liver can usually be made out. With the palpable mesenteric nodes or the fibrous bands there will be fluid in some amount. An unfolding of the umbilicus, with redness about it, producing a condition known as “ pouting,” is a suggestive symptom. Perforation at this point is not an uncommon occurrence in the experience of those who see many cases of this disease. Prognosis.—About one-half of the patients recover. Pronounced cases may go on to complete recoveries. It is a difficult matter, however, as in the instance cited, to decide when a patient is wrell. The cases with ascites promise better than do those of the fibrous type; and yet many of the latter form which promise little make complete recoveries. Illustrative Case.—A boy three years old developed tuberculous peritonitis of a pronounced fibrous type. The omental band could be seen elevating the skin across the abdomen in a distinct ridge. After several months of treatment improvement began, and there was steady progress toward a betterment until the bodies of the two upper lumbar vertebrae became involved. The child made a complete recovery event- ually from both conditions. Treatment.—The hygienic and medical management is similar to the treatment outlined for other cases of tuberculosis (p. 397). Ade- quate rest, high-protein diet, open air, and change of climate, when this may be supplied, should be provided. Drugs are of value only as a means of improving nutritional conditions. A combination which seems to possess real value in these cases is the following: For a child three years of age: 1$. Liq. potassii arsenitis njxlviij Liq. ferri albuminati . 3vj Syr. hypophosphitum (calcis et sodse) q. s. ad. 5vj M. Sig.—One teaspoonful in water after meals. The medication is given for ten days, then omitted for five days, and then resumed. Interrupted medication may be continued in this way indefinitely. 764 THE PRACTICE OF PEDIATRICS Moderate exercise may be allowed if the temperature is normal. Operation.—There appears to be but little unanimity of opinion as regards the advisability of operative procedure in tuberculous perit- onitis. Some authors are ardent advocates and give statistics to prove their contentions; on the other hand, other physicians, with equally large experience, disapprove of the operation. A logical course is as follows: If there is marked ascites with much discomfort, interfering with res- piration and heart action through pressure on the diaphragm, opera- tion is to be advised at once. It would seem that early operation fur- nishes the best chance for relief in the acutely active cases. Evidence of interference with normal peristalsis, as indicated by persistent consti- pation and visible peristalsis, means that intestinal obstruction is im- minent, and under such conditions immediate laparotomy is advised. When the above conditions do not obtain it is advisable to postpone operation, and treat the patient along the lines already defined. Some of the cases seen are absolutely hopeless at the time, showing marked tuberculous processes elsewhere, and therefore are not consid- ered fit for operation. The patient should be weighed once a week. In case of a continu- ous loss in weight and strength extending over five or six weeks, with or without fever, in spite of the advantage of diet, climate, and medica- tion, operation is to be advised, regardless of the stage of the process, providing always that there is no active tuberculous process elsewhere. When the weight remains stationary or nearly so, and there is no evi- dence of advance in the abdominal lesions, it is safe to wait for a con- siderable time before undertaking operative measures. Heliotherapy in Surgical Tuberculosis.—In the summer of 1912 Dr. Rollier, of Lysin, Switzerland, published his results in the treatment of surgical tuberculosis at the tuberculosis congress in Rome. In the town of Lysin are situated, on the snow-covered mountain, the pavilions where his method of heliotherapy is practised. It consists in exposing the body of the patient to the sun’s rays in open galleries communicating with the wards and facing due south. The actual seat of disease is un- covered for five minutes only, to begin with, as there must be no blistering or burning of the skin; the next day the region is treated for two periods of five minutes each, separated by an interval of half an hour; and on the third day these exposures are lengthened to fifteen or twenty min- utes. At each seance a larger area of skin is exposed, so that at the end of two weeks the entire body, except the head, is being exposed to the rays of the sun. The head usually requires protection for a little longer time so as to prevent congestion. Plaster jackets are rarely- used, while abscesses are aspirated and exposed in the usual manner. In the jackets windows are cut so that portions, at least, of the body are exposed. Improvement is evinced almost immediately. Fever disappears, hemoglobin and red cells approach and attain their normal standards, while increase in weight is most noticeable. Out of 369 cases of surgical tuberculosis treated thus, in 284 (78 per cent.) recovery was obtained; in 48, improvement; in 21 the condition remained stationary, while 16 (4 per cent.) terminated fatally. In visceral tuberculosis the results were excellent. In 27 cases of peritonitis and enteritis there were 17 recoveries, TUBERCULIN SKIN REACTIONS 765 3 improvements, and 3 deaths. Certainly no other treatment has given such results. The different rays (blue, indigo, violet) each play a part in the cura- tive process as well as the more recently discovered infra-red and ultra- violet rays. Some are analgesic, some have a tonic action, and others penetrate deeply into the tissues. There is no attempt to utilize any particular ray as Finsen did. Experiment has shown that fully 25 or 30 per cent, of sun’s rays are absorbed by atmosphere and"dust and that to make the treatment efficient altitude is of prime importance.1 In a study of 650 hospital cases Dr. Alan Brown2 found that 70 per cent, of the cases under two years of age giving a positive reaction proved fatal. The lesions were, with but rare exceptions, general in distribution. That infants show a high degree of susceptibility to tuberculosis was shown by the fact that of 61 infants in whom a definite history of exposure could be obtained, 41 responded to the test, and of these, 37 died of tuberculosis. In infancy a negative cutaneous reaction, except in moribund cases or in children suffering from any very acute infection, is almost conclusive evidence against the existence of a tuberculous focus. Among 100 consecutive cases of tuberculosis, 95 gave a positive re- action, the remaining 5 patients being moribund on admission to the hospital. In a child in whom tuberculosis is suspected the test should be re- peated if at first it proves negative.

In a statistical study of tuberculin tests Wahl and Gerstenberger1 were able to establish the following: “A study of the tuberculin tests performed upon exposed, suspicious, or actively tuberculous individuals of the clientele of the Babies’ Dispen- sary and Hospital of Cleveland from the year 1907 to September, 1921, showed the following findings: “1. A slight increase of positive tests in the females over the males, the former giving a positive percentage of 61 per cent, and the latter a positive percentage of 54. “2. An increase in the percentage of positive reactions corresponding with the increase in age, being 35 per cent, in infants under six months of age, and 87 per cent, in young children between thirty-six and forty- eight months of age. “3. Of the different races and nationalities, the colored race gave the highest percentage of positive reactions. “4. Patients exposed to two or more sources of tuberculous infection showed a higher percentage of positive reactions than those exposed to only one. “5. When only one source of contact existed for a patient, the mother was found responsible for the highest percentage of positive reactions, a brother or sister for the next highest, and the father for the lowest of the group. “6. Children giving a negative history of exposure showed only 15 per cent, positive reactions as against 44 per cent, for those having a positive contact history. In other words, 44 per cent, of the children giving positive tuberculin tests gave a definite history of tuberculous contact, whereas, of those giving a negative history of exposure only 15 per cent, reacted positively. “7. Scrofula gave the highest percentage of positive reactions and was followed by pulmonary tuberculosis, tuberculous adenitis, tuber- culous osteomyelitis, tuberculous meningitis, and pulmonary miliary tuberculosis. “8. By using the intracutaneous test, controlled by checking with a known case of tuberculosis, a higher percentage of positive reactions can be obtained, especially in cases of tuberculous meningitis and pul- monary miliary tuberculous, than has been usually reported. 1 Arch. Pediatrics, xl, 3, March, 1923, pp. 143-150. TUBERCULIN SKIN REACTIONS 767 “9. The intracutaneous tuberculin test, 0.1 c.c. of a 1 : 100 solution, is in practically 100 per cent, of the cases more sensitive in its reaction than the tuberculin tests performed either with the ‘tattoo’ or the ‘burr’ methods. Likewise, the test performed by the ‘tattoo’ method is more sensitive than the ‘burr,’ although the former is more difficult from a technical standpoint. “10. The intracutaneous test with a 1 : 1000 solution has always been found positive even when stronger dilutions of 1 : 10 and 1 : 100 were used. The reactions with the stronger solutions have been in general more marked, but the reaction with the 1 : 1000 dilution has been sufficient to convince us to choose it as our standard in performing the intracuta- neous test routinely.” Fig. 135. A fairly accurate idea of the incidence of tuberculosis in different cities may be gained from a study of the above chart (Fig. 135), which is taken from a report by Smith.1 “Incidence in cities of infection with tuberculosis, as shown by per- centage of positive skin reactions. Upper curves represent series reported from European cities and all show a higher percentage of positive re- actions than in American cities. The New York series represents about 1500 consecutive cases in the wards of Bellevue Hospital, Children’s Medical Division. In this series the Pirquet and intradermal reactions were done on all cases, and nearly all the negative cases were retested with 1 Tuberculosis in Childhood by Charles Hendee Smith, Bulletin of New York Tuberculosis Association, March to April, 1923. 768 THE PRACTICE OF PEDIATRICS increased doses of tuberculin. The children were all under continuous observation and the reactions were read daily for five to ten days so that the possible error due to reading was practically eliminated.” The tuberculin reaction is discussed in further detail with mention of results obtained in the use of the intradermal method on pp. 824-826. Dactylitis is characterized by a fusiform swelling of one or more of the phalanges. (See Fig. 136.) There are two forms—dactylitis syphilitica and dactylitis tuberculosa. DACTYLITIS Fig. 136.—Dactylitis. Pathology.—The lesion is the same in both types, consisting of rare- fying osteomyelitis. The process begins in the center of the bone, caus- Fig. 137.

At the same time, particularly in syphilitic types, there is a periostitis with deposit of bone cells, so that DACTYLITIS 769 eventually the bone is of much greater circumference than other similar bony parts.

Fig. 138.—Radiograph of hands in tuberculous dactylitis. Suppuration and necrosis occur. A mere shell of bone may remain which, on undergoing further necrosis, may result in the loss of the finger or toe. The disease does not limit itself to one bone. 770 THE PRACTICE OF PEDIATRICS Illustrative Case.—In a syphilitic case all the fingers of both hands were involved and also the metatarsals of both great toes. The index- and middle fingers of the right hand suffered most. On the whole, both hands were alike and appeared almost webbed, due to the swelling of the proximal phalanges, while the distal phalanges tapered in a definite penciled fashion. There was apparently no pain, and the infant used the hands with perfect freedom, The x-ray plates showed a destructive osteitis involving the bones of both hands. The radiograph reproduced in Fig. 138 shows very graphically the hone change taking place in tuberculous dactylitis. The patient, a child of eight months, had the advantage of heliotherapy. Differentiation between the two types from the clinical appearance is impossible. When the lesion is multiple, it is more apt to be of syphilitic origin, although this is by no means certain. The tuberculin test and the Wassermann reaction, in the absence of disease elsewhere, will be re- quired to establish the diagnosis, as the symptoms and appearance are identical in both forms. Treatment.—Aside from the antisyphilitic treatment, the manage- ment of the two types is the same. Absolute rest of the parts appears to be essential for success. This is best secured by the use of splints, which must be kept bound on the fingers for months in such a way as effectually to immobilize them. In a case of the tuberculous form, suc- cessfully treated in this way, the finger was kept in splints for six months. When abscess and necrosis occur, the case must be treated along surgical lines, the immobility of the parts being maintained as completely as the conditions allow. XX. DISEASES DUE TO DISTURBANCES OF METABOLISM ACIDOSIS (KETOSIS) Acidosis is a condition in which there is diminution of the alkali reserve of the body fluids, especially of the blood, usually attended by an excessive formation of acids with its resulting clinical symptoms. Etiology.—An alteration of the equilibrium and normal relationship of the alkalies and acids in the body is the direct exciting cause. The blood, in order for life to exist, must be maintained at a very constant reaction which is slightly alkaline, and there must be, within narrow limits, a certain excess of bases over acids. Any change from the normal toward the side of acidity tends to inhibit numerous sensitive metabolic processes in the organism, and acidosis results. (For the specific etiologic factors tending to induce acidosis see p. 774. Pathogenesis.—Metabolic products, especially carbonic acid, are con- stantly being formed in the tissues and poured into the blood to be trans- ferred to the lungs for elimination. This would tend to alter its normal slightly alkaline reaction to one strongly acid were it not for the alkali reserve formed by bicarbonates both in the blood and tissues, by the alkaline phosphates of sodium and potassium, and by the alkali-yielding proteins, in conjunction with efforts of elimination by the body. The slightest change in the direction of acidity is sufficient to stimulate the respiratory center through the agency of the carbon dioxid contained in the blood. The increased pulmonary ventilation removes the excess of carbon dioxid and the blood returns to its original state, as the res- piration lowers the concentration of carbon dioxid in the lungs and thus allows it to pass from the tissues where it is in greatest tension to the blood and thus to the lungs where the tension is lowest. Certain non- volatile acids, as sulphuric and phosphoric, also cause, when formed, increased pulmonary ventilation and hyperpnea, as they remove some of the alkali reserve of the blood, thus leaving more of the carbonic acid, normally produced by the tissues, to be eliminated through the lungs. These acids are for the most part eliminated through the kidneys which have the power to excrete an acid urine from a practically neutral fluid, leaving behind an alkali reserve for further neutralization purposes. An interference with the elimination of acids as well as their overpro- duction may therefore cause acidosis. A final and very efficient means of preserving the alkaline balance lies in the ability of the body to form the alkali, ammonia, from urea, a neutral substance, which thus adds greatly to the alkali reserve. Symptoms.—Acute acidosis in children usually manifests itself in two forms: as a peculiar symptom complex seen in infants, and in recurrent or cylic vomiting of older children. In the former, hyperpnea is one of the earliest and most constant symptoms. The majority of cases occur in infants who are of the marasmic type, or suffer from malnutrition 771 772 THE PRACTICE OF PEDIATRICS and who have finally a severe attack of diarrhea, following a digestive disturbance. The hyperpnea is associated with an ashen gray color of the skin and a peculiar pallor, but no cyanosis. The lips are cherry red. At first there is great irritability and restlessness which is succeeded by a condition of stupor and eventually coma. The eyes become deeply sunken and staring, and the mouth and lips dry and parched, the fon- tanels are depressed, and the respirations are of a deep and sighing character, without pause and usually labored. On being aroused from the stuporous state the child shows marked irritability, crying as though in pain. The temperature curve shows marked fluctuations, not usually going above 101.5° F. A polymorphonuclear leukocytosis ranging from 10,000 to 20,000 is found. A very scanty excretion of urine often amount- ing to anuria often obtains. The stools are usually abundant and of a watery consistency. Determinations upon the expired or alveolar air show a marked reduction in the carbon clioxid tension which may fall as low as 15 to 12 mm. of mercury from the normal of 35 to 45 mm. There is a great tolerance for alkalies, as much as five to ten times the usual amount being needed to bring about an alkaline reaction of the urine to litmus, and keep it alkaline for twelve or more hours. Acetone may not be found in the urine even in the most severe cases. Treatment.—Alkalies must be given promptly, and in sufficient quantities to bring the blood back to the normal reaction. A 4 per cent, solution of sodium bicarbonate for intravenous use best answers the pur- pose, especially where rapidity of action is desired, and should be given in amounts of 15 to 20 c.c. per kg. of body weight. This may be repeated in three to four hours if the hyperpnea has not disappeared or if the alveolar carbon dioxid tension is as low as 25 mm. (See p. 829.) The superior longitudinal sinus or the external jugular vein in infants offers a very convenient avenue of administration. In older children the median basilic may be used. Sodium bicarbonate in doses of 20 to 60 grains should also be given by the mouth every two hours until the urine is alkaline to litmus. Glucose in 10 per cent, solution administered by the bowel, or in ex- treme cases intravenously, in amounts up to 20 c.c. per kg. of body weight is the recognized easily available fuel with which deficient oxidation must be combated. To guard against excretion of this sugar in the urine the injections should be gradual. Such administration of glucose, even without alkali, tends to restore the normal alkali reserve of the blood. In intestinal intoxication there is with the usual acidosis a marked increase in the non-protein nitrogenous constituents of the blood, and the symptoms resemble those of uremia. Schloss1 has explained that the failure of the kidney in intestinal toxemia to preserve the acid-base equilibrium results from restricted formation of urine due to the dehydration so char- acteristic of the diarrheal disease. As the activity of the kidneys is at a low ebb when acidosis develops, they should be stimulated by water or salt solution given freely by mouth, rectum, subcutaneously, intraperitoneally, or intravenously. “As much as 200 to 350 c.c. may be given at a single injection to a small infant.”2 1 Amer. Jour. Dis. Child., 15, 3, March, 1918, pp. 165-189. 2 Howland and Marriott, Abt’s Pediatrics, Vol. II, chap, xxviii, p. 841. CYCLIC VOMITING (RECURRENT OR PERIODIC VOMITING) 773 Schloss1 has recommended the intraperitoneal injection of normal saline as the method of choice in the administration of fluid in severe intestinal intoxication cases. Fluid should be administered until the blood concen- tration is found to be normal by hemoglobin determination. Following this, as an adjunct of great value not so much for nutrition as to promote diuresis, he has given glucose in 10 per cent, solution, 20 c.c. per kg. of body weight. The administration of the saline before giving the glucose is par- ticularly important, as a large amount of tissue fluid is necessary to insure the requisite withdrawal of fluid into the blood-stream. This treatment may be repeated in five or six hours. (For transfusion of citrated human blood in acidosis see p. 777.) Following the prolonged administration of bicarbonate of soda in exces- sive amounts typical tetany seizures culminating in convulsions have been observed in young infants and nephritics. According to Howland and Marriott2 these manifestations ordinarily cease promptly on cessation of of the dosage, but “when massive doses of sodium bicarbonate are to be administered there are theoretic as well as practical reasons for adminis- tering magnesium sulphate subcutaneously as a prophylactic against tetany. This may be given in 8 per cent, solution in doses up to 0.2 gm. per kg. of body weight.” When it is not practicable to determine the bicarbonate reserve of the blood-plasma, these observers have recommended that the fresh urine be tested with a drop of cresol purple. “If the color remains green more alkali is necessary; if it changes to any shade of red or purple a sufficient amount of alkali has been given.” Greenwald,3 in experiments with dogs, found that only in the tetany of hyperpnea is there indication of change in the reaction of the blood follow- ing prolonged slow administration of bicarbonate of soda; and “even in this condition the tissue anoxemia resulting from increased stability of oxy- hemoglobin rather than alkalosis per se, is the exciting factor.” From the rather meager evidence at hand it would thus spem that whereas excessive alkalinization, particularly in cases of nephritis and pye- litis, may constitute a danger, nevertheless this danger is not great and may be readily avoided by careful clinical and laboratory observations in carry- ing out the treatment of acidosis cases. ALKALOSIS CYCLIC VOMITING (RECURRENT OR PERIODIC VOMITING) By recurrent vomiting is understood the disorder which for a period of several months or longer is manifested by vomiting seizures at fairly definite intervals. True cyclic vomiting or recurrent vomiting may be one of the mani- festations of acidosis, p. 770. Children who suffer from dilatation and ptosis of the stomach (p. 221) often suffer from periodic vomiting, likewise those who have mechanical intestinal defects (p. 253) and chronic ap- pendicitis. In these cases, however, the seizure is not prolonged and there is no air-hunger, no great prostration, and there are no fatalities. ‘Boston Med. and Surg. Jour., September 21, 1922; New York State Jour. Med.» August, 1918. 2 Abt’s Pediatrics, Vol. II, chap, xxviii, p. 840. 3 Jour. Biol. Chem., liv, 2, October, 1922. 774 THE PRACTICE OF PEDIATRICS There may be acetonuria as there is in any other acute disorder in children, without diminished alveolar air tension. The nature of the seizure is quite apart from the vomiting of acidosis. Etiology.—Children who have cyclic vomiting often show varying nervous phenomena, such as habit spasm, chorea, recurrent spasmodic croup, and spasmodic bronchitis. Rachford was the first to designate the underlying condition as a gastro-intestinal lithemia. Secondary Etiologic Factors.—There are certain associated conditions which may precipitate an attack in a susceptible subject. Habitual constipation with defective elimination is present in some cases. In other cases there is an associated intestinal crisis, with vomiting, high fever, and a sharp diarrhea. In others the onset may be with grip, pneumonia, or one of the exanthemata. Fright, fatigue, and unusual excitement may play a part in inducing an immediate attack. Each of these factors, however, represents the spark that ignites the powder. If the condition of systemic intoxication did not exist, any of the influences mentioned would not produce the vomiting. Runyon reported 6 cases of recurrent vomiting cured by the removal of a chronically diseased appendix. There are also seasonal influences. When the child can exercise and perspire, when he runs much and plays hard, elimination is better, and in many cases fewer attacks occur. Repeatedly, in getting the history of these cases one hears that there are no attacks between May and October. Symptoms.—The vomiting periods occur periodically. In some cases observed the attacks occurred every nine days, in others but once in three or four weeks, or as many months. Each patient involuntarily arranges his own distinct periods, and usually fulfils the contract. Prodromal symptoms have been unusual. Now and then a mother will state that she can anticipate an attack by some peculiar behavior on the part of the child—that he will lose his appetite or that the skin over the face will have a greenish or yellowish tint, or that the breath will be offensive. The symptoms are very characteristic, and occur in no other condi- tion. The child, without prodromal signs, has a sharp attack of nausea and vomiting. The nausea is extreme and the retching and straining occur at frequent intervals. There is often no elevation of the tempera- ture. There may be, however, decided pyrexia early in the attack. In Rachford’s experience an elevation of temperature is the rule in young children. There is marked prostration. The child becomes very pale. The eyes are sunken and the loss in weight is rapid. Acetone bodies are present in the urine. Neither food nor water is retained. The thirst is extreme. Eventually there is exaggerated sighing respiration, a true air-hunger. The patients beg for water, only to vomit as soon as it is given. The vomited material usually contains hydrochloric acid, wrhile in true gastritis free hydrochloric acid is absent (Rachford). The illness may last but a fewr hours, with one or two vomiting seiz- ures. In the average case the duration is from three to five days. The longest case witnessed w-as that of a boy of three years who vomited persistently for thirteen days. In some cases the vomiting is sufficiently severe to produce hematemesis. CYCLIC VOMITING (RECURRENT OR PERIODIC VOMITING) 775 I Uustrative Case.—A girl of eight years during an attack vomited such large amounts of blood that it was necessary to keep her under the influence of morphin given hypo- dermically. The Breath.—During the attack the breath usually has the charac- teristic odor of acetone. This is a sweetish odor, not unlike that of chloro- form. Observant mothers, in describing the child’s symptoms, have referred to this sign without suggestion from the physician. Examination fails to show anything abnormal except the presence of acetone, diacetic acid, and oxybutyric acid in the urine, as described by Edsall. In a mild or moderately severe case the vomiting stops abruptly and the child asks for food and retains it, providing reasonably simple food is given. In a few da vs he has made up the loss in nutrition and is as well as ever. In more severe attacks the child may require several days to regain his usual health and vigor. The resumption of the feeding will neces- sitate considerable care. Differential Diagnosis.—A first attack of cyclic vomiting may be confused with meningitis, acute indigestion, or the vomiting in acute nephritis, appendicitis, or intestinal obstruction. In the event of an abrupt onset in a first attack a diagnosis may not be made for a day or two. The differentiation laid down in some of the books is not de- pendable. Thus the vomiting which occurs as the earliest symptom of tuber- culous meningitis may be clinically identical with that of cylic vomit- ing, and only by the appearance of other signs of meningitis or through lumbar puncture is the differentiation possible. In acute indigestion there is a brief period of fever and one or two vomiting seizures, after which the patient is well. In acute nephritis an examination of the urine readily settles the diagnosis. In appendicitis there is pain and spasticity and the vomiting is not continuous; in cyclic vomiting the abdomen is relaxed, soft, and not tender. Intestinal ob- struction is an affection of infancy; cyclic vomiting rarely occurs before the second year, and usually not until after the third year. In intestinal obstruction, moreover, there is abdominal distention and perhaps the passage of bloody mucus, due to intussusception. Every child presented because of recurrent vomiting should be given the benefit of serial x-ray study of the gastro-intestinal tract. Illustrative Case.—A boy six years of age had had repeated attacks of severe recur- rent vomiting at intervals ranging from six weeks to three months. In the last seizure he had lost 9 pounds in weight. It was found upon x-ray study that the sigmoid was greatly elongated and that there was rectal stasis due to an overacting anal sphincter. In fact, the rectum was never empty. The mother, an unusually intelligent woman, was directed to insert, her finger into the rectum after a fairly free evacuation had been induced by a mild laxative. Invariably there was found fecal material in considerable quantity behind the sphincter. Dietetic measures and stretching of the sphincter were sufficient to relieve the vomiting. In the ensuing two years there were no attacks. Prognosis.—The prognosis is usually good not only as regards life, but as regards the continuation of the attacks. We have, nevertheless, seen a number of fatal cases. Treatment in the Intervals.—In describing the management of children 776 THE PRACTICE OF PEDIATRICS who show the rheumatic complex, the influence of the sugar and fat was referred to. In the cyclic vomiting cases the precaution of withholding these substances from the diet is one of the most necessary features of the interval management. Different authors refer to the fact that the use of milk in some children is productive of attacks. It is the fat content of the milk that produces the attack. These patients may take fat-free milk and buttermilk without inconvenience. The diet prescribed for the cyclic vomiting case is that laid down on p. 739. Milk-fat, sugar, and egg-yolks are forbidden. Medication.—For a child from three to ten years of age from 9 to 12 grains of salicylate of soda, or aspirin may be given after meals daily in divided doses, for five days out of fifteen. During the ten days of rest from the salicylates 10 grains of bicarbonate of soda should be given twice daily after meals. This method of treatment must be continued for months. If the salicylate of soda interferes with digestion or with the appetite, aspirin in equal dosage may be substituted. Under this method of treatment in cases in which attacks had been occurring every month or six weeks the intervals have been increased to six months or a year, and in many cases the attacks have entirely ceased. Spasmodic treatment is of little value; only persistent treatment is effective, and there must be confidence and co-operation on the part of the family or any treatment will fail. An important requirement in the management is that the patient live a normal child’s life. There should be a suitable rest period after the midday meal. Three meals are to be given daily, and there must be one free bowel evacuation daily without the habitual use of enemata. A liberal green vegetable diet with stewed fruit will do much to accom- plish this. (See Constipation, p. 274.) Treatment of the Acute Attack.—All food should be withheld. Hot bicarbonate of soda water, 10 grains in 3 to 4 ounces of water, should be given every hour if possible. If it is vomited, 1 teaspoonful of the solu- tion is to be given at a time. If this or plain water is ejected, the stomach must be allowed to rest. Medication other than the bicarbonate of soda should not be attempted. After twenty-four hours, with a con- tinuation of the vomiting, a colon flushing (p. 857) with 16 ounces of warm water containing 2 drams of bicarbonate of soda may be employed. This should be repeated at six- to eight-hour intervals. ‘It is astonishing to note how much of this solution will be taken up if the tube is intro- duced well into the colon. Repeatedly patients have been observed to retain 2 pints a day. The procedure supplies fluid, relieves thirst, and prevents prostration and loss in weight. At the same time the bicarbonate of soda furnishes the best antidote to the acid intoxication that exists. If the colonic medication is not well retained, it should be used but twice daily, so as not to establish an intolerance. Discretion must be used in giving food. Some children will have a disgust for all foods, and others will be as hungry as they are thirsty. This, however, is unusual. Twice-baked bread and unsweetened zwieback have been retained when nothing else could be kept down. Further, when the vomiting ceases and the child is on the borderland of convalescence, some one of the dried bread-stuffs often answers better than does fluid. CYCLIC DIARRHEA 777 In a general way, however, a diet of broth, gruel (particularly oatmeal), skimmed milk, and dried bread is best for the first few days following an attack. If the case proves resistant and but little of the bicarbonate is re- tained, the procedure detailed under Treatment of Acidosis (p. 772) should be instituted. Transfusion: Illustrative Case.—In a case of severe acidosis seen with Dr. Mosher, of Brooklyn, a fatal outcome seemed imminent. Bicarbonate of soda freely administered and two infusions of bicarbonate of soda with 4 per cent, dextrose, given intravenously, failed to produce the slightest improvement. Transfusion of human blood was decided upon, and 6 ounces of citrated blood was given. The improvement following the use df human blood was most remarkable. The hyperpnea ceased, the pulse improved, and the entire expression of the child changed in a very few hours. He made a complete recovery, all traces of acidosis disappearing within five days after the transfusion. CYCLIC DIARRHEA Excess of sugars and fat in the diet of children of the so-called lithemic type may produce characteristic gastro-enteric effects entirely independent of intestinal and stomach digestive conditions. Patients of this type represent those who possess a poor capacity for the metabolism of these substances. Cases of this kind are not at all unusual, and are usually attributed to errors in diet, to fatigue, to overexcitement, or nervousness. Symptoms.—There may be a prodromal period of a few days, with foul breath, coated tongue, languor, and loss of appetite. More often the onset is sudden and without warning. There is sudden high fever, headache, vomiting, diarrhea, muscle soreness, and, rarely, delirium. Abdominal pain may be present, colicky in character. The fever rarely lasts longer than two or three days—often not longer than one day. The gastro-intestinal manifestation of the toxemia may persist for a shorter or longer time. Some children will have one or two vomiting seizures; others none. The intestines, however, are much disturbed. Loose watery stools are frequent, and defecation is attended with considerable pain and tenes- mus. After an indefinite period of time—usually one to three days—the symptoms abruptly subside, and the child becomes hungry and begs for more food than is good for him. Usually after such an attack the child feels unusually well, and no evidence of the seizure remains. In the course of a few weeks the identical process is repeated, although the mother volunteers the information that the child has been carefully fed and that the attacks cannot be attributed to indiscretion in diet. Occasionally such cases are associated with cyclic vomiting. Illustrative Case.—A boy six years of age almost always—such was the history— began the cyclic vomiting attack with the symptoms as described. Vomiting ordinarily did not begin until the fever and the urgent intestinal symptoms had subsided. The attacks are quite apt to be followed by constipation. These gastro-intestinal crises become as distinctly periodic as those of cyclic vomiting and spasmodic bronchitis. A large number of these patients have been brought for treatment solely because of the periodic attacks 778 THE PRACTICE OF PEDIATRICS which are referred to by the mother or nurse as “indigestion,” “gastritis,” or “biliousness.” If the attacks are frequent, signs of malnutrition may be noted. Us- ually the patient has resistance of a low order and is apt to be nervous and pale. The muscles are flabby. The tongue may be habitually coated. The child is chronically tired, “or never quite well.” This description obtains in the most severe cases. Children, hcwever, who undergo the periodic attacks at intervals of several weeks suffer but temporary in- convenience. The acetone breath has been present during the attack in a few of the cases, although its occurrence has been the exception. Illustrative Cases.—Case 1.—A girl, three years of age, of decidedly gouty ante- cedents in both parents, had, for the eighteen months previous to examination, attacks of “indigestion” every six weeks. There was no vomiting. The temperature rarely rose above 103° F. There was pronounced diarrhea with little mucus. At each attack she had been given castor oil and a reduced diet, and was well in four or five days. Between the attacks she was fairly well, except that the tongue was never clean and there was a persistent low-grade dermatitis on the neck and upper portion of the chest, which had resisted the treatment of different dermatologists. The child had been fed with reasonable care under medical direction. There had been no gain in weight during the year. She was given a mixed diet of meat, poultry, fish, green vegetables, and cereals. One pint of skimmed milk or fat-free buttermilk was allowed daily. Sugar of every kind was prohibited. Raw fruit was not permitted. Ten grains of bicarbonate of soda was given daily for several weeks. During the twenty-one months of treatment there was no suggestion of the former trouble. Case 2.—A boy six years of age had repeated attacks of diarrhea lasting from two to ten days. The majority of the attacks occurred during the warmer weather, but there were also three or four during the winter. There was fever, rarely higher than 102° F., and rarely vomiting. Dietetic restrictions of the intake of sugar and fat were carried out, and skimmed milk in small amount was allowed during the next three months—July, August, and September—a period during which he had never before been well. He now remained perfectly well, and during this time gained If pounds in weight. There ensued no repetition of the attacks. Many histories of cases might be cited in which the periodic intestinal crises were relieved by the withdrawal of fat and sugar from the diet, and by the free use of bicarbonate of soda for protracted periods. Starches appear to exert no unfavorable influence on the condition and, similarly, sugar that is manufactured by the organism exerts no unfavorable in- fluence. What appears to be dietetic idiosyncrasy and incapacity in not a few instances has been explained by defective gastro-intestinal mechanics, sometimes in association with faulty posture. Children with recurrent diarrhea should be given the benefit of a serial rr-ray study of the gastro- intestinal tract. Treatment.—As indicated, the treatment consists in withdrawing fat and sugar largely from the diet, and in the use of bicarbonate of soda. If constipation is present, 30 grains daily of the soda may be given with sufficient aromatic cascara to keep the bowels active. Stewed fruits and cereals are usually readily taken without sugar. If necessary, small amounts of saccharin may be used for sweetening. Eating between meals is forbidden, and the child is made to take an after-dinner rest of one and one-half hours. Stress of all kinds must be avoided. PERIODIC FEVER 779 ACETONURIA IN CHILDREN Ketone bodies occur in the urine in a wide variety of disorders, and are due to defective fat metabolism. They are present in diabetes, acid- osis, inanition, and malignant diseases. They may be present in practically every other disease of childhood, particularly in the exanthemata. The presence of acetone in the urine is not necessarily due to star- vation or fever as we find it repeatedly when these conditions do not exist. We have found it repeatedly in children who were on a liberal carbohydrate diet. Illustrative Cases.—In two typical cases the patients showed a persistent acetonuria when on ordinary foods. The odor of the acetone breath had been noticed by the mother in each case. When the fats were entirely eliminated from the diet the acetone dis- appeared. A boy six years of age had repeated seizures of periodic fever, the temperature ranging from 103° to 105° F. for four or five days, without other signs than excessive acetone in the urine. There had been several of these attacks during the previous two years, one about every two or three months. Treatment during the second year had not been attempted because the child recovered just as well without treatment. “The fever had to run its course.” With elimination of fat, eggs, and cane-sugar from the diet the attacks ceased and did not recur during the ensuing five years. Children who readily develop acetonuria do not necessarily have attacks of true acidosis. Children, however, who are subject to attacks of true acidosis, will frequently have acetone in the urine with minor ailments with fever. Treatment.—Fats must be given sparingly. Cane-sugar should be given in small quantities if at all. The usual diet contains sufficient carbohydrate to supply the needs of children, without cane-sugar. If sugar is given it is best to use honey or maple sugar. PERIODIC FEVER Febrile cases somewhat resembling the above are not of unusual oc- currence. The clinical condition is that of periodic fever without another symptom. Illustrative Cases.—Case /.-—The temperature of one patient, aged four years, ranged from 102° to 103.5° F. and lasted four to six days. This child came for treat- ment because of the periodic elevation of temperature which could not be accounted for. During his third year there were six of these temperature periods. In the fourth year there were four, all during January, February, and March. There was no gastro- intestinal association and no clinical evidence of disease to account for the temperature periods. The mother stated that “the breath smelled like chloroform” during the attacks. An exhaustive examination failed to detect anything wrong with the child other than a persistent erythema at the angle of the mouth on the right side. The patient was given a diet free from fat and sugar. Thirty grains of bicarbonate of soda were given daily. Two years elapsed without a return of the temperature period. Case 2.—In the case of another boy, aged six years, the temperature period per- sisted two to five days, and the range was 100° to 104° F. During the attack the tongue was coated and the patient complained of being very tired. The attacks appeared without warning and disappeared without other evidences of illness than the fever. There was no objective gastro-intestinal disturbance. In one year there were five temperature periods; during the next year, three. In neither of these cases was there another sign of trouble than the recurring tem- perature; the children had been treated and examined repeatedly with an aim to deter- mine the cause. In all, six examples of this fever phenomenon were observed. All the patients were relieved promptly by removing sugar and cow’s milk fat from the diet, and by the interval use of bicarbonate of soda. 780 THE PRACTICE OF PEDIATRICS THE SUBOXIDATION SYNDROME1 Another group of children entirely apart from the foregoing are those who fall into our classification of the suboxidation syndrome. Children coming under this heading are usually but by no means al- ways found among the offspring of the well-to-do. The forebears of the children presenting this syndrome are usually those who have lived an indoor occupational existence for two or more generations, devoting their efforts to intellectual persuits and not to manual labor. A child with the suboxidation syndrome is one whose metabolic functions are habitually below the normal. He may be overweight or of average weight; usually he is underweight. Such children have a lowered capacity in endurance, because of physical weakness, although as a rule they are precocious and mentally overactive and possess much nervous energy. One of the striking features is the dryness of the skin with a tendency to erythema and mild eczema. Patchy areas of inflammation are par- ticularly found about the mouth. Perspiration is scanty and the child rarely perspires except on very hot days. The hands and feet readily become cold in cold weather and low temperature is keenly felt. This symptom is often remarked by the parents. In fact, extra heavy outdoor garments are required during the winter months. In most cases a moderate anemia is present. The appetite is capricious and constipation is the rule. The body temperature is usually below normal in the early morning and often rises above normal under activities and stress. One of the outstanding features of this syndrome is a marked tendency to afebrile rhinitis and bronchitis. The child is scarcely free from one attack when another supervenes. There is a chain of these respiratory affections throughout the winter. The colds are sufficiently severe and frequent in occurrence to interfere seriously with the activity of the patient, and much time is lost in school and outdoors. As might be expected, it is rare to find a patient of this type who has not had the tonsils and adenoids removed, with little or no benefit. As a class such children are rather immune to actual infection of the respiratory tract, although pneumonia and infectious bronchitis may, of course, occur. While they show a certain resistance to bacterial infec- tions of the respiratory mucous membrane, these patients quite frequently are subjects of protein sensitization; and bronchitis, when it occurs, is likely to be of the spasmodic type. Another feature of the syndrome is the tendency to attacks of recur- rent vomiting, in which the vomiting may occur only once or repeatedly for a few hours or a day or two. These seizures may have occurred at fairly definite intervals for several months or years. In some of these patients transient skin rashes or “eczema” may be the predominating manifestation. In other cases because of anemia or malnutrition or lack of increase in height for a period of several months, the physician is consulted. Other cases will afford the history of an elevation of the temperature, lasting one or more days, occurring at fairly regular intervals, without other manifestations than those of heavy breath and a coated tongue. 1 Iverley and Berman, Airier. Jour. Med. Assoc., May 1, 1920, vol. 74, pp. 1226, 1227. THE SUBOXIDATION SYNDROME 781 Not all cases show an identical train of acute manifestations. In one respect, however, these children are very similar: They have a de- fective metabolism for the soluble carbohydrates and for fats, particularly for cow’s milk fat in the amount that we have accustomed ourselves dur- ing the last few decades to give to children. Illustrative Cases.—Case 1.—A boy, aged three years, weighing 29 pounds and without physical abnormality, had been subject to recurrent attacks of elevation of the temperature since the age of one year. They occurred about every two months, being characterized by loss of appetite, coated tongue, and listlessness, with a tem- perature of from 101° to 103° F., the fever periods lasting from three to five days. There was rarely vomiting. The skin showed scattered areas of erythema. Pie was restricted to a diet free from cow’s milk fat and sugar. During the next eight months there were no further attacks of illness, and he gained 3§ pounds in weight and 2\ inches in height. Case 2.—A girl, aged six years, who weighed 471 pounds and who was without physical abnormality, had habitually a coated tongue and poor appetite. Meal times were a trial to the other members of the family. In disposition she was irritable. Her complexion was sallow and the skin was dry over the back of the neck, where there was persistent erythema. There were patchy areas of dermatitis about the mouth, causing considerable disfigurement. She was subject to frequent catarrhal colds. One followed the other so rapidly that it was difficult to say when one was finished and another began. Tonsils and adenoids had been removed without benefit. It was with concern that the parents looked forward to the approaching winter. She was given a diet from which sugar was largely excluded, enough being allowed to make the food palatable. Butter was forbidden. One pint of skimmed milk was allowed daily. Aside from these restrictions the food given was that of any well child of her age. After two months under this management she weighed 53 pounds (a gain of 6f pounds). There had not been a day’s illness. The tongue was clean and there was no trace of eczema. She was happy and good natured. During the final six months of observation there were only two slight colds, and the skin remained clear. Case 3.—A girl, aged eight years, weighing 51§ pounds, gave the history of early eczema and difficult feeding, and “had always been on a diet for her skin.” The im- mediate occasion for the consultation was the occurrence of vomiting attacks at inter- vals of from four to five weeks. The attacks usually lasted from one to two days, during which time the vomiting occurred frequently. The tongue was much coated at this time, and there was a moderate elevation of the temperature—from 100° to 102° F. After a seizure she was left very weak, and required several days for recupera- tion. The heart and lungs were normal. The blood showed 50 per cent, hemoglobin, and 4,700,000 red cells. The urine was entirely negative. She had been taking 1 quart of milk daily in addition to that used on cereals and in puddings. Sugar had been allowed with the customary freedom. She was put on the usual mixed feeding suitable for a child of her age, with restriction to skimmed milk and no sugar. After ten weeks and four days she weighed 56 pounds, a gain of \\ pounds. The mother reported that during the interval there had been no vomiting and no fever; the tongue remained clean and the bowels regular. This case was followed for five months without a return of the vomiting seizures. Case 4-—A boy, aged seven years, with a height of 471 inches and a weight of 42 pounds, came for treatment January 2, 1920, because of “frequent colds, persistent wheezing in his chest, and a cough which was relieved only by warm weather.” The condition had existed for three years, with a particularly severe cough since the pre- ceding November. The patient was thin, pale, and weak. The appetite was poor. Food had to be forced. The blood showed 70 per cent, hemoglobin and 4,200,000 red cells. The urine was negative. The heart action was rapid, but the heart sounds were normal. Examination of the lungs revealed mucous and sibilant rales fairly evenly distributed with evidence of slight bronchial spasm. The tonsils and adenoids had been removed. There was no elevation of the temperature. Acting under medical orders the child had been generously supplied with sugar, cream, milk, and butter with the idea of improving his physical condition. Our treatment was to order a general mixed diet largely sugar-free, 1 pint of milk daily, and very little butter. One pint of a Vichy water was to be drunk daily. The further instructions were that the boy should remain in bed until 10 a. m. each day, rest one and one-half hours after the midday meal, and retire at 7 p. m. He was allowed to go outdoors. No cough mixtures were given. There was a betterment of the cough in three days, with a gradual cessation com- plete in eighteen days. Fourteen days after the first examination the bronchitis had entirely disappeared. After six weeks under treatment the weight was 47 pounds, 782 THE PRACTICE OF PEDIATRICS a gain of 5 pounds, with a marked improvement in the general appearance of the pa- tient, and an entire absence of cough. The appetite was most satisfactory, and foods such as vegetables and cereals, which the patient previously had to be coaxed and forced to eat, were taken eagerly. The child remained free from the cough during observation throughout ten weeks. Comment.—A noteworthy feature in nearly every case treated has been the improvement in appetite and the marked gain in weight as soon as the fat and sugars which had been given above the capacity of the patient had been removed from the diet. Foods such as vegetables and cereals which have been taken with reluctance and in only small quan- tities are often taken eagerly. An examination of the urine in a certain percentage of these cases shows a slight but constant acetonuria on an ordinary diet, even when the patients are apparently well. Those subject to attacks of vomiting show a marked acetonuria during the attack. A great majority exhibit a marked acetonuria with acute febrile illness. A study by Dr. L. A. Berman of the blood of the patients we have come to classify by the designation “suboxidation syndrome” has shown, during the intervals of apparent health, a variable hyperglycemia vary- ing from 130 mg. of glucose per 100 c.c. of blood to 280 mg. per 100 c.c., the average being 163. The series comprised 67 cases. Of these, 27 were cases of recurrent vomiting, sometimes alternating with bron- chitis or eczema as the predominating symptom, and showed an aver- age blood-sugar of 175 mg. per 100 c.c.; 3 came for recurrent pruritus, averaging 170 mg. per 100 c.c.; 11 exhibited eczema as the predomi- nating symptom, averaging 148 mg. per 100 c.c.; 2 came for recurrent attacks of fever, with coated tongue and acetone breath, averaging 162 mg. per 100 c.c.; and 23 who had frequent colds and bronchitis as their chief complaint averaged 160 mg. per 100 c.c. The blood-sugar of 92 children not belonging to this group was also examined. The sugar content was found to range between 80 and 125, averaging 105. These subjects included those who came for examination and feeding, for malnutrition, adenoids, intertrigo, enuresis, simple an- emia, constipation, proteinogenous asthma, obesity, chronic nephritis, essential headache, chronic cervical adenitis, anorexia, acute bronchitis, tics, non-epileptic convulsions, recurrent vomiting with dilated stomach and redundant sigmoid, recurrent vomiting unrelated to mechanical de- fects, frequent colds, astluna due to enlarged tonsils and adenoids relieved by operation, migraine, urticaria, mucous colitis, flat-foot, chorea, sebor- rheic dermatitis of the scalp, cardiac disease, tetany, pylorospasm, gon- ococcus vaginitis, epilepsy, habit spasm, chronic otitis media, and enlarged tonsils. Four cases belonging to the suboxidation syndrome group were char- acterized by attacks of vomiting at the height of the attack. They showed a hypoglycemia, the figures being 80, 85, 85 and 70 mg. per 100 c.c. One case of bronchitis with bronchospasm examined in the attack had 75 mg. sugar per 100 c.c. of blood. Ten cases classifiable clinically as belonging to the suboxidation syndrome group did not show any definite hyperglycemia at the time of examination. Of these there were 4 cases of frequent colds, with an DIABETES INSIPIDUS 783 average blood-sugar of 105 mg. per 100 c.c.; 2 cases of “eczema” aver- aging 97; 3 cases characterized by recurrent vomiting averaging 106, and one of recurrent diarrhea showing 105. The method used to determine the blood-sugar was an adaptation of Benedict’s1 modified picric and picrate method to finger blood along the lines followed by Epstein in applying the original picric acid method: Of the blood, 0.2 c.c. was obtained from a finger and was immediately mixed with 0.8 c.c. of distilled water, the blood laking after a little shaking. To this, 1.5 c.c. of Benedict’s picric acid picrate reagent was added drop by drop and thoroughly mixed. The precipitated proteins were then thrown down by centrifuging. Of the supernatant fluid, 1 c.c. was taken, 0.5 c.c. of 20 per cent, anhydrous sodium carbonate added, and the mixture, corked with absoibent cotton, was placed in a water-bath for ten minutes. This was compared in the Kuttner colorimeter with a standard solution of potassium dichromate, made up by matching against a solution of glucose containing 0.2 mg. to the cubic centimeter, treated as the blood was treated, described above. Persistent polyuria—diabetes insipidus—is rare in children. The disease is characterized by extreme thirst and the passage of large quan- tities of pale urine, the condition continuing for months and years. Temporary or transient polyuria is of occasional occurrence. There is unusual thirst and the passage of abnormally large amounts of urine, a condition continuing for a few days or a week or two. Etiology.—The cause of persistent polyuria is but little understood. Cases are on record in which the condition has seemed to be closely as- sociated with brain tumors, hydrocephalus, and trauma. But 3 cases have come under our observation. In these 3 no cause could be dis- covered. Temporary or transient polyuria has been personally observed only in nervous girls of hysteric tendencies. It is most apt to develop near the close of the school year, when the child is considerably reduced or somewhat excited in anticipation of undergoing examinations. The disease is probably of congenital origin. Symptoms.—Both the mild and severe cases are characterized by thirst and the passage of large amounts of urine, ranging from 50 to 100 ounces daily. The specific gravity is low—1002 to 1010. The amount of urea and uric acid excreted varies but little from the normal. A diet low in salt and protein reduces the urinary volume. Due to the rapid excretion of fluid the skin is dry and the hair and nails may show trophic disturbances. In 2 of the cases of true diabetes insipidus there was a secondary anemia and a moderate degree of malnutrition. One patient was much undersized, and at the age of five and one-half years weighed 30\ pounds and was 37| inches high. That the lack of development was due to the polyuria, however, is extremely doubtful. Diagnosis.—Polyuria is to be differentiated from diabetes mellitus by examination of the urine. The absence of sugar determines the diag- nosis. Of further significance is the characteristic increase in the amount of urine excreted in diabetes insipidus when the ingestion of sodium chlorid and protein is increased. DIABETES INSIPIDUS 1 Benedict, S. R., A Modification of the Lewis-Benedict Method for the Deter- mination of Sugar in Blood, Jour. Biol. Chem., 34, 203, April, 1918. 784 THE PRACTICE OF PEDIATRICS Treatment.—In the cases of functional nervous origin the cure takes place by a change of environment. When the nervous stress is removed, the symptoms subside. In the true cases no means of treatment have been of avail in our hands. In the case of the boy referred to various methods of management were attempted, without success. With a diminution of the fluids taken there was a corresponding reduction in the output. As soon as the patient was allowed freedom in drinking the frequency in urination and the polyuria returned. Drugs have been of no value with the possible exception of pituitary extract, which is said to have a specific action in this condition. DIABETES MELLITUS True diabetes in children is, fortunately, a comparatively rare disease. Etiology.—Much concerning the ultimate causation of diabetes mel- litus is not known. Heredity is supposed to play an important part, but this association in our experience has been infrequent. In 11 cases in children under nine years of age no etiologic factor could be discovered. Our youngest patient was nine months of age at death. The disease in this instance was known to have existed but three weeks. Among adults, Hebrews are more liable to the disease than others. Jewish chil- dren, however, have shown no special susceptibility. Previous severe infection is now looked upon as an important etiologic factor. Pathogenesis and Morbid Anatomy.—In “A Study of the Patho- logical Anatomy of the Pancreas in 90 cases of Diabetes Mellitus” pub- lished in 1909, R. L. Cecil reviewed the work of Opie, von Mering, Min- kowski, Sauerbeck, and others, and reported that anatomic lesions of the pancreas occur in more than seven-eighths of all cases. In the cases associated with lesions of this organ the islands of Langerhans were constantly involved in changes ranging from sclerosis and hyaline degen- eration to infiltration with leukocytes and hypertrophy, while in some cases these islands were the only portions of the gland involved. In 12 per cent, of the cases investigated no pathologic changes were found, although in half of the 12 per cent, the gland was smaller, or the number of islands less than normal. Three-fourths of the cases presenting no lesions occurred in patients under the age of thirty. Abt and Strouse reported 2 cases of traumatic diabetes in children. In one the diabetic symptoms followed a fall on the head. In the other the injuries were associated with only a brief period of unconsciousness, and the chief lesion was a compound fracture of the tibia.. Both patients developed persistent glycosuria and other diabetic symptoms, and re- sponded typically to treatment. Other cases might be cited of injuries varying from simple concussion to fracture of the skull, with a subse- quent glycosuria or even permanent diabetes. Langstein recorded per- sistent glycosuria in 2 young infants affected respectively by hydroceph- alus and malformation of the brain. The subject of experimental diabetes was investigated by MacLeod. He stated that dextrose may appear in the urine as a result of deficient DIABETES MELLITUS 785 utilization of this carbohydrate by the tissues, because of deficient renal function permitting the escape of sugar normally present in the blood,1 or because of an increased production of dextrose in the liver. To the last of these sources of a hyperglycemia he attached the greatest im- portance. The hepatic conversion of the glycogen into dextrose was shown to be influenced by a reflex mechanism operating through the fourth ventricle and the splanchnic nerves. That certain drugs and the carbon dioxid present in the blood in asphyxia may produce hyperglycemia by their effects on these nerve centers controlling glycogen conversion was considered probable. The influence of an internal secretion from the pancreas, while long regarded as probably important, is only now beginning to be fully under- stood. (See p. 786.) The urine is ordinarily increased in amount, clear, acid, and of high specific gravity—1025 to 1050. The amount of glucose present varies widely, depending on the character of the diet, time of day, and time of meals. During certain periods the sugar may be absent. Acetone, diacetic acid, and beta-oxybutyric acid may be found, depending on the severity of the disease. The first two of these substances are oxidation products of the third, which appears only in severe cases. The Blood.—The normal blood-sugar in children closely approximates the adult normal (80-110 mg. per 100 c.c. blood), except possibly in breast- fed newborn infants, when the blood-sugar is probably slightly lower.2 In diabetes mellitus, however, the sugar may constitute 0.5 per cent, of the blood or even more. This varies with the diet, the time of day, and the ability of the patient to metabolize carbohydrates. There may be a moderate hyperglycemia without glycosuria, providing the sugar thresh- old has not been passed. In severe cases with marked emaciation, in addition to the clinical signs of ketosis, impending coma, and the presence of the products of intermediary fat metabolism in the urine, there may be and usually is a marked decrease in the carbon dioxid combining power of the blood. “This then is the worst picture of perverted metabolism in diabetes. Sugar cannot burn, fat burns only as far as beta-oxybutyric acid, and as for protein, a part of its amino-acids are converted into sugar and another part into beta-oxybutyric acid, neither of which can be burned.”3 Symptoms.—Diabetes mellitus is very constant in its symptoma- tology in children. An early and never-failing sign is loss of weight with- out apparent cause. The loss of weight is so pronounced that it is often the first symptom to which the attention is called. Thirst is also an early symptom. It is of a very urgent nature. The child never seems to be satisfied. The thirst is so great that the patient is awakened by it in the night and demands water. Milk or any fluids will be taken, but. if a choice is given, water will be selected. Repeatedly patients have been known, if allowed, to drink 5 or 6 pints of water a day. Frequent urination is always present, large amounts being voided; 100 ounces in twenty-four hours is not uncommonly excreted by a young 1 Under normal conditions the blood contains about 0.1 to 0.15 per cent, of glucose. 2 Lucas, W. P., et ah, Amer. Jour. Dis. Child., December, 1921, vol. 22, No. 6. 3 Lusk, Graham, The Elements of the Science of Nutrition, 3d ed., 1917. 786 THE PRACTICE OF PEDIATRICS child. Enuresis occurs in over half the cases. The skin is dry; per- spiration rarely occurs even on the hottest days or when the body is cov- ered with warm clothing. A light brawny desquamation is not infre- quently seen. The child becomes listless. There is disinclination to play, and the interest in childish things flags. The appetite is usually voracious, the child being not at all particular as to the kind of food taken. No matter how carefully the food is selected and prepared, the emaciation continues. As the case makes its inevitable progress toward dissolution the emaciation progresses and the weakness increases until the patient is confined to bed. If an intercurrent disease, such as bronchopneumonia, does not terminate the illness, the untreated child dies from exhaustion or acetonemia. Diagnosis.—The presence of diabetes is suggested by loss in weight and strength, in association with a voracious appetite and inordinate thirst and dryness of the skin. An examination of the urine and blood determines the diagnosis. The disease may be confused with persistent polyuria and with chronic interstitial nephritis. Here again the differ- entiation is made by the urine examination. Diabetic coma may be con- fused with meningitis, uremia, and other states of coma if urine examina- tion is neglected. Duration of the Disease.—Few child patients without insulin live longer than a year. The majority of cases in the past have terminated fatally in from three to six months. Prognosis.—All our child patients, except those treated with insulin, have died within less than a year after the diagnosis was made. True diabetes is a fatal disease in both childhood and youth. Treatment.—None of our patients treated by limiting the amount of fluid taken, by restricting the diet, and by using the opium derivatives and arsenic to the point of physiologic effect received the slightest lasting benefit. Bicarbonate of soda, furthermore, was given in large dosage. The sugar output was reduced, but the patients showed not even tem- porary improvement in general condition. Insulin.—The introduction of insulin by Banting and Best, working in MacLeod’s laboratory at Toronto University, has marked a tremendous advance in the treatment of diabetes. It had been pretty well established that the islands of Langerhans in the pancreas elaborate an internal secretion which is essential in controlling carbohydrate metabolism, the secretion of the acinar portion having no effect on this function. At- tempts at preparing extracts of whole pancreas had failed because of the action of the acinar digestive ferments on the islet tissue. Ligation of the pancreatic ducts, however, caused degeneration of the acinar portion of the gland, permitting the extraction of the island tissue. This extract was found to lower the blood-sugar markedly in both normal and depancreatized animals. Clinical experience has shown the efficacy of this extract in treating diabetics, especially the severe cases which occur in children. Careful dietetic measures must be maintained, but insulin raises the patient’s food tolerance temporarily. The patient’s caloric needs must be estimated, his PELLAGRA 787 protein requirements fulfilled, a limited amount of fat provided, and sufficient carbohydrate added to make up the rest of the calories and in- sure complete combustion of the fat. Then sufficient insulin should be injected hypodermically to keep the blood-sugar close to normal limits. Rather than render the urine sugar free, it is better to bring the blood- sugar close to normal and permit a slight glycosuria. This acts more or less as a buffer against the occurrence of a hypoglycemia which is a very real danger. Clinically an overdose of insulin causing hypoglycemia mani- fests itself by marked hunger, weakness, vasomotor instability, accelerated pulse, sweating, vertigo, delirium, convulsions, low temperature, low blood-pressure, and death. The rapid administration of glucose by mouth or intravenously, as the case may require, will raise the blood-sugar and cause the symptoms to subside. Whether the continued use of insulin permanently increases carbo- hydrate tolerance remains to be seen. At present the dose must be given hypodermically from one to four times daily, depending upon the severity of the case, in order to maintain the increased food tolerance which this extract provides. In each case the balance between diet and the amount of insulin must be'carefully studied. Diet.—The following are the ordinarily permissible articles of diet for a child ill with diabetes: Soup and broths made from meat, fresh and salt fish, shell-fish, occasionally egg, fowl, and game, smoked meats, sweetbread, cheese, spinach, celery, lettuce, cucumbers, cranberries, rad- ishes, stringbeans, asparagus, squash, cabbage, egg-plant, tomatoes, onions, turnips, mushrooms, gelatin jellies sweetened with saccharin, butter, cream, olive oil, cod-liver oil, lemon, grape-fruit, sour apples, blackberries, raspberries, watermelon. Nuts of all kinds may be eaten. Only bread and biscuits made from gluten flour should be used. It is impossible to procure a starch-free gluten flour; the flour, however, should not contain more than 20 per cent, of starch. PELLAGRA Pellagra is a systemic disease with a course typically marked by intermissions, affecting chiefly the skin, gastro-intestinal tract, and ner- vous system. This disease has undoubtedly been endemic in Southern Europe for centuries and has long been known under such names as “Alpine Scurvy,” “Corn-bread Disease,” and “Italian Leprosy.” In the past two decades it has assumed special prominence in the Southern United States. The first recorded descriptions are those of Cazal and of Frapoli, made about the middle of the eighteenth century. Today it is estimated that there are 100,000 cases in Italy and at least 25,000 in the United States. Etiology.—Pellagra has been generally regarded as a metabolic dis- ease of food origin rather than an infectious disease. Dermatitis of the characteristic type has been produced experimentally by Goldberg, in individuals who were fed on a diet rich in maize and rice to the ex- clusion of animal and legume proteins, but whether the condition is due to deficiency of vitamins in maize, toxins derived from maize, posions germinated in diseased corn, or should be viewed as an example of anaphyl- axis affecting particularly tissues sensitized by exposure to the sun has 788 THE PRACTICE OF PEDIATRICS not been elucidated. One of the most interesting theories as to the origin of pellagra is that of Alessandrini and Scala, who stated positively that it is a form of chronic acid intoxication caused by colloidal silica in drinking- water and that the disease is localized and contracted only in those regions where the water-supply is derived from clay soils. The explanation of the production of the disease is thus purely biochemic: The silica in colloidal solution attaches to protein substances, and in this manner it fixes salts in the tissue cells of the body with the liberation of water and an acid—most frequently hydrochloric acid. The abstraction of the water and the diminution in alkalinity of the tissue fluids thus in- duced are productive of the drying of the tissues and the acid intoxication which are so characteristic. Objections to the vitamin deficiency theory and to the colloidal silica theory have been met more or less convincingly by the respective advo- cates of each belief, but the predominant view today is that pellagra is a vitamin-deficiency disease, or a low-grade infection of intestinal origin. Spring and fall are the seasons of greatest incidence of pellagra and, similarly, these are the times for recurrences of the disease in aggra- vated form, once it has gained a foothold in a given subject. Most of the patients are between the ages of twenty and forty years and only about 9 per cent, are under the age of fifteen years. Cases observed in infants have never been proved in any degree hereditary. Pathology.—The skin lesions exemplify changes varying from an early erythema-like sunburn to thickening, pigmentation, and atrophy. Except for atrophic changes in the gastro-intestinal tract and fatty de- generation of the viscera, the most pronounced additional effects of the disease are confined to the spinal cord and brain. There is an en- dothelial proliferation in the capillaries of the pia with some connect- ive tissue increase, together with diminution in the nerve-cells of the cortex and a considerable degree of gliosis. In the cervical cord the posterior columns show degeneration, and in the dorsal region the lateral columns are similarly affected. Symptomatology.—Following a prolonged “incubation” period marked by malaise the average pellagrin gives evidence first of digestive disorder. This is indicated by redness and coating of the tongue frequently com- bined with actual stomatitis, flatulence and abdominal cramps, and diarrhea. At some period the last-named symptom occurs in fully 85 per cent, of cases. Almost as soon, if not equally early, the skin on the exposed parts of the body becomes the seat of an erythema which de- velops into actual dermatitis. After a few weeks this inflammation sub- sides, leaving the integument bronzed and indurated over a period of possibly many months. Mental derangement is common, but this symptom in children calls for only passing mention. Vertigo and headache are not infrequent and many patients show a positive Romberg test, and upon ocular examination, changes in the retina and anomalies in the fun- dus reflex. The lower tendon reflexes are usually exaggerated, but are at times diminished. The disease ordinarily runs a subacute or chronic course with a tendency to subsidence during summer and winter, with recurrences, as has been noted, during spring and fall. At these periods renewed severity in the cutaneous and gastro-intestinal symptoms is the PELLAGRA 789 rule. Rises of temperature are not common. Malnutrition and anemia are invariably present, but the changes in the blood are in no way pathog- nomonic. As a rule there is with the anemia a slight leukocytosis and a moderate mononucleosis of from 10 to 20 per cent. The urine contains an excess of indican. Prognosis.—In children pellagra is ordinarily less severe than in adults. The adult mortality in the white race has been estimated at 27 per cent. Complicating diseases including principally tuberculosis, malaria, and hookworm disease doubtless contribute to this high mor- tality. Notwithstanding the tendency of pellagra to run a chronic course over months and years, occasional acute cases are observed which prove fatal in as short a time as a fortnight. Diagnosis.—Pellagra may at times be confounded with eczema, scurvy, dysentery, tuberculosis, and leprosy. The character and dis- tribution of the cutaneous lesions, the significant digestive disturbances, the peculiar course of the disease, and the history of other cases in the locality where the patient has resided are the points of greatest value in reaching conclusions in a given case. Treatment.—Preventive measures under Health Department super- vision are essential in all communities where pellagra is endemic. Rules to govern the care and sale of corn in such communities are justifiable, even though spoiled maize shall be proved to have no part in the causa- tion of the disease. In view of the findings of Alessandrini and Scala, drinking-water should be provided which is free from excessive quantities of colloidal silica. All cases of the disease should be reported and given opportunity at least to have the advantage of institutional care. Gold- berger recommended a diet rich in legumes and animal proteins, com- prising milk, eggs, and meat. Baths, salt rubs, and massage are of special value in the management of cases in children. Most authorities admin- ister arsenic up to the physiologic limit, with intermissions of a few days at stated periods. Fowler’s solution, atoxyl, and sodium cacodylate are the preparations of choice. The last of these has been administered intramuscularly with good results by Deaderick and Thompson in dosage of 3 grains daily for an adult. Quinin hydrobromate has received par- ticular advocacy from Dyer. Serotherapy, consisting in injections of serum from cured patients in healthy individuals, horse-serum specially pre- pared according to the method of Nicolaier, or serum from the patient himself (autoserotherapy) has given favorable results in a number of instances. Alessandrini and Scala believed the specific treatment is the admin- istration of alkali to combat the acid intoxication produced by silica. The preparation of choice is sodium citrate, and this they administered hypodermically in a 10 per cent, solution. Oral administration was also found by them to be effective. Sodium bicarbonate may also be given freely. With any form of specific therapy symptomatic treatment must be employed and this demands the use of local applications for the skin lesions, intestinal astringents and antiseptics, and mouth-washes, pref- erably containing chlorate of potash. Concurrent diseases, such as hookworm disease and malaria, should not be neglected. 790 THE PRACTICE OF PEDIATRICS BERIBERI Beriberi is a disease the leading characteristics of which are mul- tiple neuritis and general edema. The disease occurs in individuals whose food is deficient in a certain vitamin. Etiology.—Beriberi is most common among rice-eating Oriental peoples, but is endemic also in Brazil. The prevailing view held for a considerable time was that the specific cause was a micro-organism which elaborates a toxin productive of neuritis. This view has now given place to the theory of food deficiency. Thus in the last two decades it has been established that the disease is prevalent only among peoples sub- sisting largely on a diet of rice which is “polished” or highly milled. The removal of the husk of the rice with the subjacent layer containing pro- tein and fat leaves little but the starch, and such rice has been shown to be deficient in antineuritic vitamin and phosphorus. The phosphorus pentoxid content is more or less directly proportionate to the amount of vitamin present and rice containing less than 0.4 per cent, of P205 will cause beriberi, whereas rice containing more than 0.4 per cent, will prevent beriberi.1 Lack of vitamin in other starch food may similarly be responsible for the disease in people who do not eat rice, but subsist on a similar unbalanced ration. Overheating of food destroys the vit- amin. Symptoms.—The leading manifestations are multiple neuritis and edema. When paralysis predominates the term dry or atrophic beriberi is applied to the disease; if the edema is pronounced, the term wet beri- beri is employed. Fever is seldom noted. Progressive asthenia, weakness in the legs, cardiac palpitation, and shortness of breath constitute the early manifestations. With the progress of the affection symptoms of multiple neuritis become apparent, such as localized sensory and motor disturbances. Coincidently localized edema develops in the extremities. Edema in the serous cavities of the body may follow. Nausea, vomiting, and epigastric discomfort are common. Eventually foot-drop, wrist- drop, and atrophy of the muscles affected by the neuritis develop. Blood examination reveals only the existence of a simple anemia. The urine may contain albumin, but seldom shows the presence of elements indic- ative of nephritis. Special forms of beriberi are the rudimentary type, the fulminating or pernicious form, and infantile beriberi. The last type devel- ops in infants of mothers who have the disease and is characterized by vomiting, edema, and symptoms of cardiac failure. Diagnosis.—Sporadic cases may be difficult of diagnosis. In children beriberi may be confused with nephritis, alcoholic neuritis, and the neu- ritis of diphtheria. The habits of life of the patient, the distribution of the paralysis, and the urinary signs aid principally in confirming a doubt- ful diagnosis. Leprosy accompanied by neuritic manifestations is at times mistaken for beriberi. Prognosis.—The death-rate varies markedly in different epidemics, ranging from 2 per cent, among Japanese soliders who were treated in military hospitals to as high as 50 or 60 per cent, among untreated and ignorant peoples. In individual cases the prognosis should be guarded 1 Barker, Monographic Medicine, vol. iv, p. 777. ACRODYNIA 791 as in cases of post diphtheric paralysis because of the constant danger of sudden cardiac failure. Treatment.—Prophylaxis is most important. A well-balanced diet is sufficient to prevent the disease in an individual who will observe the ordinary laws of hygiene. Nursing mothers who have the disease should promptly be made to cease nursing. Treatment of the developed disease is largely symptomatic. The diet should be light but nutritious, and contain the elements lacking in polished rice. Brewer’s yeast, powdered rice husks and adzucki, and mango beans are among the articles recom- mended as favorable to a cure. Rice itself should be removed from the diet. Saline laxatives are of great value and the use of these should be supplemented with the administration of diuretics, such as potassium citrate or even diuretin. Cardiac stimulants which do not upset the stomach are of value at times,-but the routine use of digitalis has few advocates. For the vomiting small doses of morphin are permissible if bromid proves ineffectual. As soon as edema disappears affected extrem- ities should be treated by passive movements, massage, and electricity. Complete change of climate and environment does most to promote con- valescence. ACRODYNIA For a careful sifting of the literature relating to this disease we are indebted to William Weston, who gives to J. B. Bilderback the credit of being the first to recognize and describe this disease in the United States. Weston claims to have found authentic account of its existence in Europe as late as the sixteenth century. A recent contribution by this author1 aroused a great deal of interest in the disease, and a considerable number of additional contributions from different sections of this country have appeared. That this condition constitutes an entity appears to be estab- lished and that it will eventually be classed among the deficiency diseases is probable. Symptoms.—In a personal communication Weston has described the symptomatology as follows: “The onset of the disease may be either abrupt or so gradual that its true nature may not become manifest for several weeks. Usually the first symptoms to attract attention are: the child becomes peevish and fret- ful, loses his appetite, and sleeps poorly. Soon the feet and hands become red and swollen accompanied by intense itching or burning of the palms and soles. A rash may also appear on the tips of the nose, the ears, and cheeks or it may cover the entire body except the back of the neck. Soon after the rash appears desquamation begins. The desquamation some- times involves all the layers of the skin and deep necrotic ulcers form. Usually, however, the desquamation only involves the superficial layers, leaving a bluish-red, glistening surface, feeling cold and clammy to the touch. These areas may be either hyperesthetic or anesthetic. Coinci- dent with the symptoms just enumerated occur profuse irritating sweats that add to the child’s discomfort. It becomes pale and emaciated. The eyes become irritated and very sensitive to light. The hair becomes dry and thin and areas of alopecia appear. The muscles become flabby 1 Arch, of Ped., September, 1920. 792 THE PRACTICE OF PEDIATRICS and if the child has walked it can no longer do so. It lies with its face buried in the pillow or against its mother’s shoulder, its hands in constant motion, its feet rubbing against each other, and constantly moaning or begging that its feet be rubbed. Such a picture of abject misery once seen can never be forgotten. “Skin.—The skin manifestations are uniformly present and invariably involve the palms and dorsal surface of the hands and soles, less often the dorsal surface of the feet. They are cold, clammy, and cyanotic. There occurs an erythematous rash most marked at the tips of the fingers and gradually diminishing until at the wrists or forearms it entirely disap- pears. There is no line of demarcation as in pellagra. “Less often there occurs a rash on the tip of the nose, the ears, and cheeks. Occasionally the entire body except the neck is covered with an erythematous rash. The rash may be constant or it may disappear and recur. When it disappears pigmented spots appear. As the rash fades there will occur a desquamation which may involve only the superficial layers of the skin or may involve all layers. The surface is bathed in a pro- fuse, irritating sweat. The extremities are invariably edematous, but there is no pitting upon pressure. Less often this edema may be observed about the face or other parts of the body. The rash usually appears as an erythema, but may appear as macules, papules, or pustules, and in a given case all these may be observed. “The trophic changes in the skin may at times be very severe and re- sult in gangrene of the fingers or deep ulcers on the toes or soles. “ Hair.—The hair is dry and tends to fall out. It not infrequently hap- pens that the child pulls out ‘handfuls’ of hair. In other cases it will pull out hair by hair, leaving bald spots. “Eyes.—Photophobia with conjunctivitis and lacrimation are the rule. Sometimes injections of the cornea and keratitis are present. “Teeth.—Loss of teeth with or without pathologic changes in the gums is a manifestation often observed. “Nails.—Change in the color of the nails is of frequent occurrence. Shedding of the finger and toe nails occurs in many cases. “Genito-urinary.—Pyelitis accompanied by frequent and painful mic- turition and irregular fever is met with in many cases. Both albumin and acetone are found occasionally. “Gastro-intestinal.—Loss of appetite is common. Anorexia is often present. Diarrhea and vomiting are met with in a small proportion of cases. “ Nervous System.—Irritability, restlessness, insomnia, and trichotillo- mania occur in nearly all cases. Paresthesia of the fingers, hands, toes and feet, especially the palms and soles is invariably present. Convul- sions occur in a few cases. “Glandular.—Cervical glands are often enlarged. “Reflexes.—The reflexes may be unaltered, increased, diminished, or abolished. “Muscular.—There occurs a distinct loss of tone in all the muscles. They become flabby and atrophy. Sometimes marked contraction takes place. “Respiratory.—A nasopharyngitis is usually present. This occasionally ACRODYNIA 793 develops into a bronchitis or a bronchopneumonia. Very occasionally a pulmonary edema occurs. “Circulatory and Blood.—The heart rarely shows any change. A sec- ondary anemia is present in a fairly large proportion of cases. “ Temperature.—A slight rise in temperature often occurs. High tem- perature is seldom met with unless due to some complication. “Laboratory Findings.—There usually exists a fairly regular relative polymorphonucleosis and an increase in the total number of leukocytes. “The red cell count is not materially altered. The Wassermann is uni- formly negative. “Spinal fluid negative. “Tuberculin skin tests and Schick tests negative. “Blood-cultures uniformly negative. “Feces negative for parasites. “In cases studied from a metabolic standpoint it was observed that there was a lowered or negative nitrogen balance in some and in others a negative balance of bases. The excessive loss of nitrogen and bases occurred through the urine.” Diagnosis.—The disease most commonly mistaken for acrodynia is pellagra. This error is not likely to be made if one recalls the following points: Acrodynia occurs at any season; pellagra usually commences in the spring or fall. Acrodynia shows no tendency to recur, produces a less persistent rash than pellagra, typically involves the body in an erythematous rash, seldom affecting the dorsal surface of the feet and ankles, seldom produces a severe diarrhea, does not occasion insanity but produces most acute wretchedness associated with the marked itching and burning not present in pellagra. Finally, acrodynia ultimately terminates in recovery, whereas in pellagra there is a comparatively high mortality. Prognosis.—Spontaneous recovery is the rule. In fatal cases death has been due to complications. Treatment.—The management consists in attention to the various symptoms as they appear. None of those observers who have described cases appear to have any definite line of treatment. This disease seems to be intractable. Weston feels that lack of Vitamin B may be an important factor in the etiology. XXL DISEASES OF MUSCLES, BONES, AND JOINTS DIAGNOSIS IN BONE AND JOINT DISEASES It is not within the province of this book to enter the domain of ortho- pedic surgery. The practitioner, however, is the first to see cases of ill- ness regardless of their nature, and bone and joint diseases are no excep- tion to the rule. For this reason these diseases will be considered largely from the standpoint of diagnosis. In the examination for bone and joint diseases in runabout and older children the patient should invariably be stripped. He should then be encouraged to move about, to run and play, to sit down, to lie down, to roll over on his stomach and back again. He may be asked to pick up toys, to walk up and down stairs, to climb into a chair. By these means limitation of motion, a most valuable symptom in joint disease, is made apparent. Acute Peri-arthritis.—In infants and young children observed in hospital work an infection of the peri-articular structures is not at all uncommon. The symptoms presented are those of superficial swelling, and at times redness and pain upon manipulation. Fluctuation will be present if the case is at all advanced. The shoulder- and elbow-joints in our cases have been the more frequently involved. The disease may be due to any of the pathogenic organisms. In one case an examination of the pus showed pure influenza bacillus infection. The gonococcus may produce either a peri-arthritis or an arthritis. Elevation of tem- perature is an inconstant symptom. Arthritis.—In arthritis the symptoms are usually more urgent. The temperature usually is higher, 102° to 104° F., and there is complete loss of power in the limb involved, associated with pain, swelling, and red- ness. As in peri-arthritis, any one of the pyogenic organisms may be the infecting agent. Arthritis of one or more of the larger joints is not in- frequent following sinus thrombosis with septicemia. In such cases the Streptococcus hemolyticus has often been the infecting organism, and its portal of entry to the body, the middle ear. Gonorrheal Arthritis.—In gonorrheal arthritis the lesion is apt to be multiple. As many as five joints have been observed to be involved in one patient. The small joints of the hands are particularly apt to be involved in infants with gonorrheal arthritis. Arthritis and peri- arthritis are often confused with rheumatism. In the non-gonorrheal cases the urgency of the constitutional symptoms and the severe local lesion, with the rapid development of pus, render a diagnosis fairly simple. In gonorrheal arthritis one may have to look to the age as a point in differentiation. Children under eighteen months rarely have rheumatism, and in the very young, successive, severe, inflammatory joint infections should always arouse the suspicion of an infectious arthritis. Joint Tuberculosis.—While tuberculosis may develop in any bony structure, that form with which we are particularly concerned in diag- nosis affects the hip and spine. 794 DIAGNOSIS IN BONE AND JOINT DISEASES 795 Tuberculosis of the spine may occur in quite young infants. Our youngest patient was nine months of age. While the symptoms vary somewhat, depending upon the location of the inflammation, one symp- tom is almost always present early in the illness—stiffness, a tendency to hold the body rigid. The child moves awkwardly. If the cervical vertebra are involved, the head will be held fixed on the shoulders, often with a bearing slightly either to the right or the left, resembling the attitude of torticollis. If the dorsal or lumbar vertebra are in- volved, the child holds the body erect and all movements are made with care and caution. The shoulders are thrown backward, the child assuming a military attitude. Bending the body is difficult. When the child attempts to pick an object from the floor, the spine is held rigid, while extreme flexion takes place in the knees in order to bring the hand to the floor. In every motion the child attempts to protect the sensitive spine, making all voluntary motions with precision and apparent forethought. Pain referred anteriorly may be present, not always early in the case. Early in the disease there is no deformity. The first objective sign to appear is a projection or undue prominence of one or more of the spinal processes. After the development of the angular bony deformity the disease is unmistakable. Tuberculous Disease of the Hip.—This is very rare in infancy. The first symptom is a slight limp, due to spasticity of the hip muscles, which causes the child to step short. The onset of the disease is very gradual, and the limping may disappear for weeks at a time and return again, and again disappear. Pain is an inconstant early symptom, but may be indicated by night cries. Pain in the anterior portion of the thigh just above the knee may occur early. Illustrative Case.—A boy twelve years old had a periodic limp or short step for six years; he had been treated for various conditions, particularly for rheumatism. An orthopedist, after several weeks of observation assisted by an x-ray, pronounced the condition tuberculous. A shortening of the gluteal fold and a general flattening of the hip with an increased prominence of the trochanter are characteristic of hip disease. The tendency to spasticity of the hip muscles furnishes a most val- uable diagnostic aid. There is a general limitation of motion as com- pared with that of the sound side: abduction, adduction, flexion, exten- sion, and rotation are all retarded. The joint appears fixed. Tilting of the pelvis, due to the muscular spasticity, consists in an elevation of the patient’s back from the table when the extended leg of the affected side rests fully upon the table. In more advanced cases there is the eversion of the foot. Outward rotation of the entire limb and apparent lengthening, pain, inability to walk, and abscess are the outcome in cases unsuccessfully treated. Knee-joint Tuberculosis. — This form of tuberculous joint disease follows in order of frequency the two just discussed. The condition develops gradually, perhaps following an injury, and soon gives rise to 796 THE PRACTICE OP PEDIATRICS slight flexion and rigidity of the knee with an early morning limp which may wear off during the day. Eventually the child maintains the knee in fixed flexion, walking on the toes. The joint gradually develops swelling as the case progresses, and this enlargement is typically spindle shaped, covered with tense, shiny skin. To this appearance the term “white swelling” is applied. The x-ray is invaluable in showing the underlying joint condition. Atrophy of the muscles of the thigh and calf accentuate the swelling. The prognosis in this condition depends upon its early recognition and effective treatment both locally and constitutionally. The tend- ency to ascribe the existence of a lame knee in a child to insignificant trauma or “growing pains” is indirectly productive of the crippling of many, who might otherwise have timely help. Dactylitis.—This condition has been considered on pp. 768-770. “Quiet hip disease” (Legg’s disease; Perthes’ disease) is an affection easily diagnosed incorrectly as tuberculosis of the hip-joint, and for this reason deserves mention. Flattening of the head of the femur with thinning of the epiphysis and hypertrophy of the neck of the bone comprise the characteristic features. Trauma, rickets, and infectious epiphysitis have been suggested as causes. The affection is one of the middle years of childhood. The symptoms are slight lameness and moderate limitation of motion, particularly in rotation and abduction. The diagnosis is confirmed by x-ray, which shows evidence of atrophic changes at the epiphysis with possibly thickening of the neck of the femur. In most of the cases reported the symptoms have subsided under conservative treatment directed toward protection against weight bear- ing and overuse of the hip. Joint fixation is only exceptionally indicated.1 Infective Osteomyelitis.—The infecting organism in most cases of acute osteomyelitis is Staphylococcus pyogenes aureus which may gain access to the bone through the blood-stream from a remote focus or through direct extension from a nearby compound fracture wound. The localization of this infection in the bone is attended by sudden onset of fever and pain. The pain is most intense and may involve the whole affected bone. Leukocytosis and general manifestations of sepsis supervene, and metastases of the organisms to other bones may occur. The picture of profound sepsis which is not readily explained, even in the absence of pain, should always lead to examination for osteomyelitic foci. Rheumatism and typhoid fever may be readily excluded, even with- out the aid of positive x-ray findings. Radical surgery combined with supportive measures of every available type, including transfusion, offers the only hope in these cases. OSTEOGENESIS IMPERFECTA (FRAGILITAS OSSIUM; OSTEOPSATHYROSIS INFANTILIS? LOBSTEIN’S DISEASE) This disease is characterized by multiple and repeated fractures of bones, particularly long bones. Practically nothing is known of its etiology. The association of this 1 Jones and Lovett, Orthopedic Surgery, 1923. CHRONDRODYSTROPHIA (ACHONDROPLASIA) 797 tendency to fractures in families whose members have blue sclerotics has been noted. The bones show markedly defective calcification together with a paucity and inactivity of the osteoblasts so that the bony trabeculae are small and few. Multiple intra-uterine fractures are common, but most of these chil- dren are still-born or die shortly after delivery. Shortening because of frac- tures and bending of extremities in these newborn infants simulate chon- drodystrophy. Roentgenograms of the bones show diminished density. The skull is parchment-like in consistency but, if the patient survives, later assumes a rather characteristic shape, broad and flat, sometimes with a projecting ridge of bone around the posterior and lateral aspects just above the level of the ears. The features are small in proportion to the head, with a rather sharp nose and a long pointed mandible. In the surviving cases fracture may occur from very ordinary handling and is difficult to prevent. Later, as the stumbling stage is passed and cal- cification becomes more complete, the tendency to fracture becomes less. The bones, however, often remain brittle and fragile throughout life. There is no treatment beyond protection from trauma. Union of the fractures usually occurs quite normally. Illustrative Cases.—A child, B. S., male, one year of age, was brought with a history of disability of the left leg dating back four weeks. There was no known trauma. The child had been born by cesarean section at which time the mother died. The history of development for the first eleven months was uneventful. Roentgenograms of the affected leg showed a fracture of the middle third of the left tibia and later plates showed good repair with periosteal bone formation along the shaft. The epiphyseal lines were prominent and calcification of the shaft appeared less dense than normal. Typical blue sclerotics were present. Hemoglobin was 58 per cent. (Dare). Otherwise physical and laboratory examinations were in every way negative. The mother of the patient had the following history of repeated fractures from trivial causes: At two years, complete fracture of tibia and fibula from falling one step; at four years, compound fracture of right ulna from stumbling to ground; at four and a half years, fracture of right malar and nasal bones from a blow; at eight, fractured rib from a blow of bicycle handle bars; at ten, fractured metacarpal and phalanx from a fall to the ground; at seventeen, a double fracture of the pelvis when falling from a horse. The mother did not have the blue sclera nor did another child, a sister of the first patient described. This other child, P. S., female, also born by cesarean section, was a difficult feeding patient with secondary anemia. At one year, at two years, and at four and a half years she suffered fractures of long bones. All the fractures in the three members of this family made normal repairs as regards duration and restored function. Other ascertainable family history was negative. CHONDRODYSTROPHIA (ACHONDROPLASIA) Achondroplasia is a disease of fetal life characterized chiefly by de- fective development of the long bones. The terms applied to this disease constitute a long list. Some of these are “fetal rickets,” “micromelia,” “chondromalacia,” “fetal chon- dritis,” and “chondrodystrophia fcetalis.” Emerson1 has cited many examples from Egyptian, Grecian, and medi- eval art, which go to prove the antiquity of this disease. He further states that of all dwarfs, those with this affection have been most popular in the positions of court clowns and jesters. The condition has long been 1 Osier, Modern Medicine. 798 THE PRACTICE OF PEDIATRICS confused with rickets, cretinism, and certain types of syphilis. Parrot first made clear the pathologic distinctions in 1878, and Porak gave a very full account of the subject in 1890. Etiology.—Heredity is an influential but not, apparently, an unfailing factor.1 In many instances there is no family history of a significant char- acter. Emerson has suggested that achondroplasia and rickets may be related, in spite of the usual variance in their manifestations and the evidence against the occurrence of so-called intra-uterine rickets. By many achondroplasia is thought to be due to defective function in one or more of the glands of internal secretion. Syphilis is sometimes as- sociated with this affection, but cannot be said to be a cause. Pathology.—The lesions are localized in the bones, more particu- larly the long bones and those of the base of the skull. The epiphyses are primarily affected. Here there is always defective formation of cartilage, whence the descriptive name, chondrodystrophy. Periosteal growth goes on, and, by invading the region which is normally supplied with bone by the cartilage cells, impairs still more the cartilaginous formation of bone, interferes with the union of epiphysis and diaphysis, and checks the growth of the bone in length. The irregular co-operation of the chondral and periosteal tissues in the development and growth of the bones similarly explains the actual deformities in their shape. Most of the cases belong to the type known as hypoplastic. The epiphyses are normal in size, and there is impaired growth of the cartilage cells. In the hyperplastic form, however, which is rare, the growth of cartilage exceeds the normal, and the epiphyses are enlarged. In chondrodystrophia fcetalis malacia the epiphyses are soft, due to decrease in the consistence of the intercellular matrix. Symptoms.—The dwarf presents a peculiar appearance. To such a degree is this true that he is often a source of revenue. These individuals have normal intelligence, and being quick to turn their physical defects into pecuniary gain, they may often be seen on the vaudeville or comic opera stage doing minor roles as foils to men of large stature. The trunk is of normal size, while the extremities are very short. The head may be involved. It may be very large, showing a dome- shaped contour, not unlike that of hydrocephalus. The features may be large, with broad nose and prominent cheek bones. The forehead is usually wide, with the eyes set widely apart, due to the broad root of the nose. The facial appearance, as described, while usually pres- ent, is not necessarily a part of the picture. Cases are occasional in which the facial configuration differs in no wise from that of the general average of humanity. The muscles of the extremities, while short, are very large and strong, often affording these little people prodigious strength in lift- ing or carding heavy objects. The appearance of the child is characteristic, further, in that the hips are very heavy and broad, this appearance being produced in part by the peculiar articulation of the thigh with the trunk. The articulation takes place at almost a right angle, due to the change in the contour of the neck of the femur. There is marked lordosis, the lumbar curve being markedly exaggerated. (See Fig. 139.) This causes a tilting and narrow- 1 See Prognosis, p. 800. CHRONDRODYSTROPHIA (ACHONDROPLASIA) 799 ing of the anteroposterior diameter of the pelvis, which in females may be a factor influencing childbirth in later life. The hands are usually square, and the fingers very short. The feet take on the same appearance, being short and thick. Diagnosis.—Chondrodystrophia may be confused with rachitis or cretinism in the first few months of life. Rachitis and chondrodystrophia have been confused, usually for the reason that chondrodystrophia is such a rare condition that it was not so generally known to exist. The very short, thick extremities, together with the facial charac- teristics and normal mentality, are sufficient for a differentiation. Fur- Fig. 139.—Chondrodystrophia. Lateral view. Fig. 140.—Chondrodystrophia. ther, the changes due to rachitis are of gradual development, and are never present at birth, while in chondrodystrophia the child, when very young, shows an appearance as characteristic as when he is two years of age or older. Cretins are very degenerate mentally. They are slow and stupid, exhibit no mental responsiveness, and show but little irritation upon manipulation. In chondrodystrophia the mental condition is normal; at least those with chondrodystrophia cannot be placed in the class with the mentally defective. 800 THE PRACTICE CF PEDIATRICS Prognosis.—Our observation does not bear out the claim of a high infant mortality in chondrodystrophia. Physical Health.—Of 5 supervised infants, all are well and thriving in their own way. One is the offspring of a mother who is a chondrodys- trophiac. The father of another is a chondrodystrophiac. Both men and women dwarfs have normal reproductive functions. Giving birth to children, however, is often a dangerous procedure for such women because of the anteroposterior narrowing at the pelvic brim and a tilting of the pelvis. Treatment is of no avail, no means having been discovered to induce growth. It has long been our practice to try to improve the physical condition of our patients through the development of correct posture in the very young, and to correct abnormal posture in those that come to us for other causes. A great mistake is for the physician to feel that his duty to a child under his care is finished when he treats him for an illness. It was through the writer’s efforts for better body building in his earlier years that he came to appreciate that defective mechanics played a not inconsiderable role in the development of the child and often bore a direct relationship to persistent functional ailments of the gastroin- testinal tract in particular, sufficient to interfere gravely with the child’s future health and bodily prosperity. The conditions of flat-feet, bowed legs, knock-knee, spinal curvature, and actual disease of bony structure have been admirably cared for by the orthopedist. The influence of posture upon physical function in children has, however, received scant attention. The necessity for proper supervision of growing children has been emphasized by Robert J. Cook, who calls attention to the fact that among 1393 first year students at Yale University he found that but 25 per cent, of the men had a normal spinal curvature, that over 50 per cent, had some scoliosis, and that over 55 per cent, had an increased anteroposterior curv- ature. The chest was flat in 56 per cent, of cases and the abdomen was prominent beyond the normal in 42 per cent. “Without an analysis of a large group of men it would be difficult to realize that poor posture is so common. “When it is considered that those defects are found in men who have just completed their high school or preparatory school we become impressed with the seriousness. Living in a period when the cry is for preventive medicine one wonders why we wait until the individual is developed before an attempt is made to correct defects of posture which yield to corrective therapy so much more readily in the child than in the adult.” 1 In what constitutes a correct posture for a child there should be an equalized muscle balance. This is described by F. D. Dickson2: “He should hold the head erect and directly over the chest, and hold the chest up in a forward position. The scapulae should lie fairly flat THE INFLUENCE OF DEFECTIVE BODILY MECHANICS ON HEALTH 1 New York Medical Journal, February 7, 1923. 2 Jour. Amer. Med. Assoc., vol. 77, No. 10, p. 760. THE INFLUENCE OF DEFECTIVE BODILY MECHANICS ON HEALTH 801 against the chest and the shoulders be held back, without muscular strain. The spinal curves should be slightly convex backward in the dorsal region and convex forward in the lumbar region. The abdomen should be flattened and held up and in by the muscles. All the muscles of the neck, chest, back, shoulders, and abdomen should be in slight contraction without strain or effort.” The above quotation cited by Nicholson1 presents a picture contrasting markedly with Nicholson’s own description of the cases of abnormal posture as showing in varying degree the following: “The chest flattened, with diminished anteroposterior diameters; the ribs approximated; the shoulders rounded and the scapulse alar. The back has an exaggeration of the normal curves, and the abdomen is relaxed, owing to weak muscles, protruding markedly, especially below the umbilicus. The pelvis is tilted down and forward, and in many cases the knees are slightly flexed, as a compensatory measure.” Figure 141, A shows a boy who well fits the above description. In our attempts at improving posture and body mechanics we found that children so affected presented a very similar group of symptoms. As a rule they came to us not on account of the abnormal posture but because of some pronounced gastro-intestinal disorder of a chronic nature, such as recur- rent vomiting, habitually poor appetite, or chronic and often obstinate constipation. Such patients usually suffer from secondary anemia. They lack ambition and initiative, they tire readily and constitute a consider- able number of those whom we classify as subjects of tardy malnutrition. For the past eight years we have been making a considerable x-ray study of the gastro-intestinal tract in children who have shown persistent gastro-intestinal disorders, as described at different times in medical lit- erature. The association of the ptosis position (Fig. 141, A) with gastroptosis as proved by the x-ray was striking. Not every child with gastroptosis or other defective gastro-intestinal mechanics has a faulty position, but al- most every child with a pronounced faulty posture will reveal under x-ray either gastric or intestinal ptosis, or both. Unquestionably, there are children who have ptosed stomachs, V-shaped colons, and elongated sigmoids who do not have faulty posture or relaxed abdominal walls. It is these who are the least likely to show symptoms, as strong abdominal muscles supply the necessary support to compensate for the abnormality. The writer has previously called attention to the use of abdominal support in treating ptosis in children, and can only reiterate with added emphasis that the most useful individual measure that applies to all types of ptosis, both of the stomach and intestines, is the use of proper ab- dominal support. For the average case of ptosis the Aaron belt, with or without shelf, as the case may require, answers our purposes satisfactorily. For the posture cases we were unable to find a suitable support until our attention was called to the Universal supporter as described by Nichol- son (Figs. 142-144). In this device we have support for the relaxed abdominal muscles, a splint for the lordotic spine, and a brace for the sagging shoulders, all of which are due in a measure to weak muscles. The digestive organs are thus held in better position and the stomach 1 Penna. Med. Jour. 802 THE PRACTICE OF PEDIATRICS empties better and “on time.” Sharp angulations are removed from the intestine and constipation is consequently made easier to manage. Mechanical assistance with a suitable dietetic regime, adequate rest, and right exercise not only produce a rapid and marked change in the physical well-being of a patient but also rapid gain in weight. Illustrative Case.—Our most pronounced example of a case of this type is sig- nificant. The patient (Fig. 141) presented one of our worst cases of celiac disease. A B Fig. 141.—The Nicholson supporter: Effect on posture apparent on comparing A and B. At the age of three and a half years his weight was 22 pounds and he was emaciated to a skeleton, with an enormous belly and marked muscular atrophy. Tetany develoi>ed and was very troublesome. Calcium chlorid appeared to control this, but was found necessary for months. During the next year there was a very irregular gain in weight with never a cessation of the characteristic loose, excessively large, rancid stools to the number of perhaps two or three daily. Varying diets and schemes of manage- ment were tried, with little or no improvement. There were two attacks of scurvy dur- ing this time. For two years the boy was unable to walk. An abdominal belt had been worn intermittently without any pronounced effect. THE INFLUENCE OF DEFECTIVE BODILY MECHANICS ON HEALTH 803 On November 11, 1922 his age was five years and one month, his weight was 26§ pounds, and his height, 36 inches. The weight was 7 pounds less than at the onset of the illness when he was two years and seven months old. On the above date we de- cided to supply a Nicholson supporter, but this was not brought into use for six weeks. On February 21, 1923 his weight was 28 pounds, 9 ounces, a gain of 2 pounds, 5 ounces having been made after the brace had been brought into use. Then, for the first time in his illness, the mother admitted improvement. His disposition was much better, he wanted to play and was trying to walk in spite of the fact that he made a very poor showing. His position was, nevertheless, better, although the abdomen was still very much distended. The stools now showed an improvement in that there were days when they were fairly normal; then there would be characteristic celiac stools for a day or two. On May 19, 1923 his weight was 33 f pounds and his height was 37 5 inches. Walking had improved but he could not go upstairs unassisted or pick up objects from the floor. As there was still a tendency to tetany, calcium chlorid was continued. A mixed diet was now taken suitable for a child of his age. On August 25th the mother reported the height 39 inches and the weight 38 pounds. During the three weeks preceding her report he had gained 3f pounds in spite of an attack of whooping-cough. At this writing he is on a general mixed diet. He still Fig. 142. Fig. 143. Fig. 144. has some difficulty in walking and cannot run, but can pick things from the floor and go upstairs. The posture is better and he is very comfortable in the supporter and asks to have it replaced when it is taken off. The cuts show the posture and general position tremendously improved. The lordosis and the large abdomen still persist, and the supporter will have to be worn for a couple of years. The mother is insistent in stating that no food agreed until he began to wear the abdominal support with which he is represented after a gain of about 10 pounds. Our results with the Nicholson supporter have been, on the whole, satisfactory. From our observation we believe that Nicholson’s claims are not exaggerated that the supporter aids in producing an improved posture, with a resulting correction of gastro-intestinal mechanics, and that its use is followed by greater improvement in persistent gastro- intestinal disorders than the measure would at first estimate seem to warrant. XXII* MISCELLANEOUS SUBJECTS HEREDITY AND ENVIRONMENT Many of the diseases, crimes, and failures of life are attributed to heredity, as are also vigor of body, attainments, and successes. Hered- ity and environment are two important determining factors in the life of the child. Both exert their influence over the individual. Most of us have been taught, or in some way conceived the idea, that the influence of heredity was predominant; but as a result of the closest association with developing children involving intimate relations with hundreds of them essential to watching carefully their physical and mental develop- ment, the great influence exerted by environment, which often means only opportunity, is forced upon one. This relegates heredity to the background. That certain diseases, such as syphilis and hemophilia may be transmitted from parent to child is undisputed; that certain physical states—the so-called constitutional vices—may also be trans- mitted is indisputable; but that much of natural physical weakness and hereditary tendencies may be overcome by the beneficial influence of environment is now universally acknowledged. Place a child or one of the lower animals, with an ideal heredity, under unfavorable conditions of environment and the favorable heritage counts for little. Feeding, and general good management shape physical future much more than care, does inheritance. In proof of the supposed inheritance of mental traits, offspring of criminals or drunkards are pointed out as showing how children follow in the footsteps of their fathers and mothers. It must be admitted that here the hereditary influence is bad, but one should remember that the environment has also been very unfavorable. Mental traits much more than physical conditions are apt to have an influence on the progeny, although here, again, brilliant fathers rarely transmit their higher mental powers to their offspring, as is proved again and again in the professional and business world. Many of the ills laid at the door of heredity are due to errors in early management. In the breeding of animals great stress is laid upon pedigree, and credit is given accordingly. It should be remembered, however, that the stock-raiser appreciates the value of the young of his herds, and they invariably get the care that is best calculated to develop the perfect animal, which is exactly what the majority of the children of the human family do not get. A well-bred animal, treated from birth to maturity as are many children, would cut a sorry figure in the animal world. Hereditary influences in animals are much more apt to obtain be- cause of the comparatively short period of growth from infancy to ma- turity. The age of puberty in the lower animals is reached in most in- tances before the first year. In the human the development is much slower, supplying a much longer time for the influences of environment to make their impress upon the individual. 804 TEMPERATURE IN CHILDREN 805 CONSANGUINITY Much has been made of the supposed unfavorable influences exerted upon the offspring by parents closely related by blood. Consanguineous marriages, however, exert very little influence on the progeny if both parents are in good health and there is no latent familial defect in either. If, on the other hand, there is a decided family taint or weakness the tendency toward this weakness is inevitably exaggerated in the offspring of two persons in whom the trait is dominant. The outworking of this law may be observed in a study of the transmission of such defects as color-blindness and hemophilia. The writer has known first cousins to marry and have children in all respects normal, and in two instances under his observation fathers had impregnated their own daughters, with normal children the outcome. Similarly, in the animal world the close breeding of brothers and sisters and parents and offspring has resulted in normal vigorous young. Doubtless if this in-breeding were continued through successive gen- erations the outcome would be disastrous because of the establishment of a hereditary uniformity of type with certain unbalanced potentialities. It is practically important that, whereas the laws of heredity impose fixed general principles, these principles are of broad scope. TEMPERATURE IN CHILDREN Normal Temperature.—The question is often asked: What is the normal temperature of a baby or young child of a given age? In order to answer this question from direct observation, a study of the matter was carried out by Dr. H. G. Myers, resident physician at The New York Infant Asylum. This study comprised 59 cases, the ages varying from birth to one year. Only well children were selected for the observation, the majority being breast fed. The temperature in each instance was taken by the rectum for four minutes. It was found that the birth temperature in these infants ranged from 96° to 98° F., exceeding 98° F. in but 5 cases, when it was between 98° and 99° F. In one it was 94° F. During the twenty-four hours fol- lowing birth there was a rise in the temperature usually of about one degree. From this time on there was little variation in the temperature, when the child was well, regardless of the age. There would be a vari- ation at different times of the day of a fraction of a degree, the tem- perature being higher in the evening. Upon looking over the charts upon which the results were chronicled, one is impressed by the uniformity of the temperature, which ranges, within fairly narrow limits, from 98° to 99.2° F. Instances when the temperature arose to 99.5° F. were occasionally seen, but 100° F. was very unusual. It is not claimed that the tempera- ture of a well child may not reach 100° F., in fact, there were occasions when it rose to 101° F. and illness could not be proved, and had not the temperature been taken for the purpose above mentioned, no elevation would have been suspected, for the next reading was normal. In those cases in which a rise was proved to be an early sign of illness, the special temperature record was discontinued and the first reading was not in- 806 THE PRACTICE OF PEDIATRICS eluded in the observations. In one child a temperature of 103° F. was found. It remained at this point for three hours, when it fell to normal without any other manifestation of trouble. When, however, the ther- mometer registered over 99.5° F., some cause for the elevation could usually be discovered, though it may have been nothing more than excitement or slight indigestion. Several years ago a similar series of observations was made at the Country Branch of the New York Infant Asylum upon 25 healthy children under eighteen months of age. The temperatures were taken four times a day, the observations extending over an entire week. It was found that in these well children the temperature varied from 98° to 99° F.; and that when it rose daily above 99.5° F., some abnormal condition was always found. From these observations upon 74 well children, ranging in age from birth to eighteen months, whose temperatures were taken several hun- dred times, it would seem that a daily rise above 99.5° F. may be con- sidered abnormal. An occasional rise, however, considerably higher than this, as above mentioned, may occur and does occur in perfectly healthy children, without any special significance. Fever.—By fever we understand an increase above that which is con- sidered the normal body temperature. In children, for clinical purposes, the rectal temperature should al- ways be taken. With those under five years of age the mouth observa- tion is unsafe, because the child is apt to bite off the thermometer bulb, and unreliable, because the lips will not remain closed the requisite three or four minutes. The axillary temperature is thoroughly misleading and should never be depended upon. One-minute thermometers are often unreliable. Hyperpyrexia.—The highest temperature personally known to the writer, and not due to sunstroke or insolation, was 111° F. This was as high as the thermometer could register. This extreme fever occurred in a child of ten months who was in a convulsion which was one of the first symptoms of tuberculous meningitis. The child had been placed by the parents in water at a temperature of 115° F., and had been in the water about ten minutes before the rectal temperature was taken. How much the tem- perature was due to the illness and how much to the hot water will never be known. The temperature responded promptly to a cold bath. The child never regained con- sciousness and died of meningitis ten days after the initial convulsion. Fever as an Indication.—Fever may or may not be an index of the gravity of a disease. Thus we frequently see a temperature ranging from 103° to 105° F. in tonsillitis, acute indigestion, and stomatitis— ailments which respond very quickly to treatment and which present no serious aspects. In typhoid fever, pneumonia, scarlet fever, and diphtheria, however, when the temperature range is above 104° F., it is a symptom of considerable value, as indicating the severity of the infection. It is, therefore, not the fever itself, but the condition back of and associated with it, which makes it a sign of clinical value. In pneumonia children bear a comparatively high temperature, 104° F., for example, without much discomfort or danger; while in the acute intestinal disorders of summer an equal degree of fever is borne very TEMPERATURE IN CHILDREN 807 badly, and if continued is of grave significance. These considerations must be kept in mind in our dealings with fever. Importance of Fever.—When is a given temperature to be interfered with? This question concerns all practitioners. The answer depends to a great extent upon the cause of the fever and its effects upon the patient. If the fever produces diminished assimilation, loss of sleep, irritability, and restlessness, it will do the child harm by diminishing the normal resistance to disease, and should be relieved whether it is 102° or 105° F. Interference is thus dependent not so much upon the height of the tem- perature as upon its effects upon the patient. Methods of Relieving Fever.—Elimination.—This applies particularly to the gastro-enteric tract and the skin. In a majority of the cases of high fever due to acute indigestion with resulting toxemia, purgation, bowel washing, and a carefully adjusted diet for a day or two secure recovery. We remove the cause of fever, and the fever subsides. Unfortunately, this means of controlling fever is limited to disorders of the gastro-enteric tract. Hydrotherapy.—By far the most satisfactory means of controlling fever is the local abstraction of heat by means of sponging (p 840), tub- baths (p 843), and cool packs (p 841). Antipyretic Drugs.—Much which borders on the sensational has been written about the harmfulness of antipyretic drugs, particularly the coal- tar products. Used in large and frequent doses, they certainly may do a great deal of harm. Under certain conditions, if used in small doses and repeated at intervals of from three to six hours, these drugs may be, and often are, of benefit. Aconite and liquor ammonii acetatis are of some value, as above stated, but they are of little value in controlling a very persistent high temperature. The coal-tar products furnish the best anti- pyretic drugs, and these may be used with safety, but should be used only when, for any reason, the abstraction of heat by the application of cold is impossible. In many families there is too little intelligence to make a cold pack either possible or safe, while in severe cases of pneumonia, scarlet fever, and the intestinal diseases, sponging often will not answer. Sponging and tub-bathing, if repeated too frequently, particularly during the night, exhaust the child. Moreover, these procedures are often strenuously objected to by parents as well as by the patient, and if the nurse is one of the family, her sympathy will counterbalance her judgment, and the result be far from satisfactory. Under such con- ditions, when the application of cold to the skin is impossible, a combi- nation of phenacetin and caffein, alone or with Dover’s powder, has proved effective. The antipyretic treatment of scarlet fever is the same as that of pneumonia or typhoid fever. To a child of one year, 1 grain of phenacetin with | grain of citrate of caffein may be given and repeated at three-hour intervals if the temperature requires it; to a child two years of age 1| grains of phen- acetin and | grain of citrate of caffein at three-hour intervals; three years and over, 1| to 2 grains of phenacetin with \ to 1 grain of citrate of caffein, at intervals of from three to six hours. If there is much rest- lessness and irritability, which is not thus controlled, Dover’s powder may be added—\ grain to each dose, for a child of from three to six months 808 THE PRACTICE OF PEDIATRICS of age; grain between six and twelve months; 1 grain after the age of two years is reached. It is always wise to caution parents as to the use of Dover’s powder. They should be told that if the child becomes “heavy” or unusually sleepy, the powders must be discontinued. That phenacetin and citrate of caffein cannot be given in solution is unfortunate. Like all insoluble powders, they are best given in some mucilaginous mixture, such as barley-water or one of the cereal jellies. Fruit juice or apple- sauce usually answers well. Antipyrin, for the reason that it forms a tasteless mixture with water, succeeds well with some intractable children, and may be used in the same doses as phenacetin, although as an anti- pyretic the antipyrin is less efficient. OBSCURE ELEVATION OF TEMPERATURE Perhaps the most annoying cases in pediatric work are those with an elevation of the temperature for which no adequate cause can be dis- covered. In the section on Normal Temperature (p. 805) certain possible variations are given which are regarded as within the limits of health. When these boundaries are passed, when there is a temperature range between 99° and 101° or 102° F., or a temperature persistently at 100° or 101° F., without any apparent cause, and continuing for days and weeks, the medical adviser is not in an enviable situation. Such cases are sometimes easy of solution. At other times, however, the cause of the fever may never be discovered, and the patient eventually gets well, leav- ing us still in ignorance of the cause. Active Exercise in Nervous Children.—This is not infrequently the cause of an elevation of the temperature. Illustrative Cases.—Case 1.—A country child three years of age, whose temperature every afternoon at 1 o’clock was 102° F., while not vigorous, showed no signs of ill- ness. He ate well, slept well, and played hard. There was a slow gain in weight. The fever was discovered by the mother, who thought that the child, who was a blonde, looked flushed every day at about the same time. The temperature by rectum was normal in the morning and normal at night. This condition, to the attending phys- ician’s knowledge, had persisted for six weeks before the writer saw the patient. How long there had been a daily elevation of the temperature above the normal before the mother discovered it we have no means of knowing. The family doctor, an excellent practitioner, had suspected, examined the child for, and treated him for, various dis- eases; at first for malaria, with no response to quinin; then typhoid fever, as by sug- gestion and constant inquiry the child came to imagine that he must be sick, and com- plained of languor. The fever continued, however, beyond the usual time allowance for typhoid fever and there were no other symptoms. There was no enlargement of the spleen and the blood had been repeatedly found negative to the Widal reaction. Other possible causes of the fever were also given attention. One day the doctor suggested tuberculosis. This aroused the family and friends and a consultation at the child’s home was the immediate result. A rather thin boy three years old was presented. The family history was excellent. There was one other child, six years of age, who was a good specimen of robust boyhood. The patient had never had a pulmonary disorder and no disease of the respiratory tract other than slight bronchitis. There was no apparent association of the condition with any intestinal or infectious disease. An exhaustive physical examination failed to reveal any abnormality other than a small umbilical hernia and a slight enlargement of the inguinal and submaxillary glands. The blood was not examined. The child was pale, and doubtless a blood examination would have revealed a mild secondary anemia. The appetite was fairly good; the bowels were reported regular and the stools normal. The child had not been kept in bed, as the family did not consider him very ill. After the negative physical examination the mother was questioned very closely as to the child’s habits of life. OBSCURE ELEVATION OF TEMPERATURE 809 He rose at 7 a. m., had breakfast at 7.30, and played with his big brother and two older boys until 1 o’clock, when he had dinner. A glass of milk and a piece of bread and butter were given as a luncheon at 11a. m. He played very actively, kept up with the older boys, and was unhappy when he was not with them. Attempts had been made without success to entertain him with less strenuous play. It was at midday, sometimes before, sometimes after dinner, that the temperature reached the highest point. It seemed, therefore, that here, probably, was a case of fatigue temperature. Accordingly, it was suggested that the boy be undressed and put to bed at 11.15 a. m. after the light luncheon and be made to rest and sleep if possible. At 1.15 p. m. he was to be taken up for dinner, his temperature first being taken. These instructions were faithfully carried out, and this ended the daily rise in temperature. The case was one of an active, nervous child becoming overtired in his attempts to hold his own with older and stronger boys. The patient improved rapidly in his physical condition and after an interval of several years was still perfectly well. Case 2.—Another child, four years of age, was seen in consultation because of a daily elevation of the temperature ranging from 100° to 102.5° F., which had con- tinued for six weeks. The child was thriving and otherwise perfectly well. No cause for the fever could be discovered in his physical condition. He had a noisy, excitable nurse, who was inclined to exciting games and rough play. With dismissal of the nurse the fever ceased. Otitis.—Persistent fever, following the acute catarrhal affections of the upper respiratory tract and the exanthemata, is somteimes ex- plained by a suppurative process in the middle ear, without other symp- toms than the fever. Encysted Empyema.—A small focus of encysted empyema may ex- plain a persistent fever following pneumonia. Holt described a most interesting case of this nature in which there was for over four weeks a temperature range from 100° to 105° F. Autopsy showed a small col- lection of pus between the diaphragm and the lung. Periodic Fever.—Not infrequently we see cases which show clinical signs of malaria as regards periodicity in the temperature, but without splenic enlargement or the presence of the malarial organism in the blood. Yet, often, these cases quickly respond to full doses of the bisulphate of quinin. Typhoid Fever.—Occasionally a low persistent temperature eleva- tion, obscure for a week or two, proves to be due to a mild typhoid. Tuberculosis.—An elevation of the temperature is sometimes the first premonitory symptom of tuberculosis. Tuberculosis in a child is usually an active process when it involves the lungs, and can readily be made out. When other parts are involved, such as the bones, glands, skin, or peritoneum, the manifestations are usually also sufficiently plain to indicate the condition. More obscure cases of persistent slight elevation of the temperature have been explained by an infection of the mediastinal glands. The tem- perature is usually not high (99|° to 101° F.) and is most pronounced after activity. Illustrative Case.—Recently 2 children came under observation, aged two and four years. The temperature in one case had continued for three months. In the other there had been an unexplained indefinite temperature for longer or shorter periods for over a year. Both patients showed by x-ray evident tuberculous infection of the mediastinal glands. In confirming the diagnosis of concealed lymph-node tuberculosis the x-ray is invaluable. 810 THE PRACTICE OF PEDIATRICS D’Espine’s Sign.—In 1907 D’Espine described a sign which he con- sidered diagnostic of enlargement of the bronchial lymph-glands, irrespec- tive of the cause of the enlargement. This sign consists simply in whispered bronchophony in the interscapular space and may be present in cases of leukemia, Hodgkin’s disease, syphilis, and other infectious diseases than tuberculosis. According to D’Espine the transmission of the whispered voice normally ceases at the level of the seventh cervical spine posteriorly. Transmission of bronchophony below this level is very strongly sug- gestive of tuberculous involvement of the mediastinal lymph-glands. In making the actual test the examiner applies his stethescope firmly in the interscapular space at varying levels as the patient says, “three- thirty-three.” When the sign is definitely positive the final “e” persists like an echo after the actual whisper is terminated.1 Morse, from a study of “D’Espine’s sign in childhood,”2 concluded that the change in voice normally occurs at a level between the seventh cervical and first dorsal spines. This study was based on 666 patients of the better class seen in private work, and in this group the sign was found positive in only 6 per cent. Analysis indicated that in half of the 6 per cent., the glandular enlarge- ment was not tuberculous. It is the consensus of opinion of many observers that in the diagnosis of tuberculosis D’Espine’s sign is of undoubted value but should be con- sidered not alone, but in conjunction with other physical signs and symp- toms. Intestinal infection due to chronic constipation may be the cause of persistent fever. In a suspected case, in the absence of bowel symp- toms, it is well to give a laxative and put the child temporarily on a re- duced diet consisting largely of carbohydrates. Pyelitis of mild degree may produce a slight elevation of the tem- perature, which may be difficult of solution. Several specimens of the urine may fail to reveal pus. In doubtful cases the urine should be drawn by a catheter and examined by culture methods. Unexplained Elevations of Temperature.—Children exhibit an un- explained temperature of from 100° to 101.5° F. for weeks, without any other signs of illness. One may employ all the newer diagnostic labor- atory methods, and still see such patients recover without a diagnosis. Of one thing, however, we may rest assured: If a competent, thorough examination does not reveal the cause of the slight fever we are safe in concluding that there is nothing of very serious nature back of it. The fact that milk does not agree with a child may mean that the child is mildly sensitized to cow’s milk protein and reacts accordingly with a moderate fever. Periodic attacks of elevation of the temperature from 101° to 104° F., explicable only on the grounds of a disturbed metabolism, are occasionally encountered. Except for the finding of acetone in the urine these cases are negative throughout. The pyrexia lasts four or five days and then subsides by crisis. The acetone is not the result of starvation, and the case is not one of true acidosis. 1 Stoll, IT. F., Amer. Jour. Dis. of Child., 10, 1915, pp. 183-193. 2 Amer. Jour. Dis. of Child., 11, 1916, pp. 276-280. NEUROCIRCULATORY ASTHENIA (EFFORT SYNDROME) 811 Illustrative Case.—The history of a case of this kind, which gave no end of trouble and annoyance, may not be without interest. The patient, an eight-year-old boy, was the only son of a habitually anxious mother, who had unfortunately learned to use the clinical thermometer. She' took her boy’s temperature after school one day early in December and found that the thermometer registered 100.5° F. The writer was consulted, saw the boy in the evening, took his temperature by mouth, with his own thermometer, and found it 100.8°, F., with no other evidence of disease. The boy was perfectly normal in every other respect. He maintained that he felt well, did not need a doctor, and wished to be let alone to study his lessons. The following morning the temperature was 100° F.; in the evening it was nearly 101° F. For six weeks this temperature range continued, never below 100° F., never higher than 101.2° F. Finally the mother became reconciled to “doing nothing” for her son, and he was taken to a nearby winter resort. The boy had an excellent time at the winter resort, played with his sled in the snow, skated on the lake, and fell through the ice once and received a thorough wetting, without harm. In three weeks he returned, improved as much as any city child improves from a country outing. His temperature was not taken.during these three weeks at the winter resort and has not been taken since, except when there have been evidences of illness. NEUROCIRCULATORY ASTHENIA (EFFORT SYNDROME) There is but one classification of normal children and such are sup- posed to be of the same physical and mental capacity. Two ten-year old boys may be equal in general intelligence as shown by the Binet-Simon test, yet one will be able to accomplish much more than the other in a given time. There is no mental test for initiative, incentive, or mental endurance. Because of the lack and the difficulties of an adequate classi- fication not a few children are placed at a decided disadvantage. The capacity for continued effort, which means the ability to work, counts for just as much as does the spontaneous intelligence that the child may possess. It has long been our observation that children divide themselves into groups as relates to individual ability for effort. This tendency to group- ing is not discernible to any extent among infants. After the second year, however, individual traits and a distinct personality manifest them- selves. At about this period it may be said that the child begins to in- dividuate. During the late international war, English Army surgeons learned that, when certain recruits were put to prolonged hard work, at drill, hikes, and other exertion, they failed to measure up to the endurance standard required of a soldier in the field. Although these recruits had passed the various physical tests and had been put to training, after a time it was found necessary to disqualify the men because of their inability to perform the duties and bear the hardships demanded, which others were able to meet. To this condition Dr. Thomas Lewis applied the term “effort syndrome.” As the most prominent symptoms involve the circulatory and nervous system, later writers have used the term “neurocirculatory asthenia” or “neurocirculatory myasthenia” (Mac- Farlane). This condition in healthy individuals, Lewis qualified by the term “constitutional.” Friedlander and Freyhof1 reported on 50 cases of so-called “consti- tutional neurocirculatory asthenia.” Robey and Boas,2 after an intensive study of a large number of soldiers 1 Arch. Int. Med., December, 1918. 2 Jour. Amer. Med. Assoc., August 17, 1918. 812 THE PRACTICE OF PEDIATRICS suffering from neurocirculatory disorders, were obliged to recommend for permanent discharge 87 per cent. These cases all belonged to the so-called “constitutional” class. The boy or girl who may qualify for the diagnosis of neurocirculatory asthenia comes to us with a typical story, which, condensed, is that the child is bright and responsive but lacks capacity for sustained effort, both mental and physical. It is stated that the child is intelligent but cannot apply himself sufficiently to become an average student and is behind in his classes. In like manner he is physically unfit for the usual activities of boyhood. He tires readily and prefers to be a spectator rather than an active participant in games and other amusements. Wherever endurance is required he fails. If he attempts in later life to make the football or baseball team, he is “turned down” by the coach or trainer. Neverthe- less he is not ill, and even upon a thorough physical examination will fail to show disease. One of the distinguishing characteristics is a lack of nervous control. The weight and height apparently have little to do with the condition. In the writer’s case records the child of this type has been heretofore classified as a “poor individual.” The individual boys and girls of this type are subjected to a good deal of unjust criticism. They are accused of being lazy, indifferent, care- less, and dull. The fact is they are poor types of human machines of from 50 to 75 per cent, working capacity. It is important not to confuse these young people with those who suffer from bad habits, as regards their sleep, rest, and general hygiene, or with those who are bodily ill, or with those who, because of rapid growth and arduous duties, are temporarily but not permanently below normal. It may readily be understood that in girls such constitutional peculiarities may attract less attention and be more readily excused when present. With suitable management in all such cases there will always be a sustained response. Illustrative Cases.—Case 1.—A young man now twenty-three years of age came under the senior author’s care at the age of six months. He was the oldest of 3 children and the only boy. The father was in fair physical condition. The mother was delicate in the sense that she had very little resistance or stamina. Frequent rest cures were necessary. She had backaches and headaches habitually, was nervous, thin and pale, and always had been a care to her parents. The boy had the usual illnesses of childhood and suffered considerably from diges- tive disturbances in the early years. He was irritable at home and rather unhappy in school. His school life proved very strenuous and was interspersed with frequent intermissions for one cause or another. Mental control was defective. Tantrums were not unusual. As he grew to older boyhood, various boarding schools were at- tempted, but he never remained longer than the Christmas vacation. It was uni- formly found by the head master that the school was not suited to the boy. When the United States entered the war he volunteered in a certain department and was accepted, passed the physical examination, remained a few weeks, and then was assigned to another division of the service. Thither he went, and was examined and again accepted, but in a short time was advised to apply to another department. Again he was accepted and again he failed. The boy was anxious to enter the service as all his friends had volunteered and 2 younger sisters made his life miserable by their anxiety to have a big brother hero. It was absolutely impossible for this boy to do the work required of him in any of the positions he attempted, although he was most anxious to serve. (These individuals finally drift into the right occupational sphere, one that requires very little expenditure of effort.) Case 2.—A boy who was a fine physical specimen was frequently ill in early boy- hood but never seriously ill. He had a tendency to be introspective and moody. He NEUROCIRCULATORY ASTHENIA (EFFORT SYNDROME) 813 did not like school and could not get along very well with other boys. His school attendance was interrupted by headaches, attacks of indigestion, and various nervous disorders, particularly hysteria and “brain storms,” all of which were produced by mental concentration. When he was twelve years of age he was ashamed to go to school, because he was so far behind others of his age. With private tutoring he was able to enter the primary department of a large boy’s school at the beginning of the autumn term, but just before the Christmas holiday, the mother had a letter from the head master telling her that in his opinion their particular school was not suited to the requirements of her son. Work in the garden produced dizziness. As a young lad he would ride his bicycle down hill two miles to the village and pay some public conveyance to take him and his bicycle home. He is now a well-meaning, well-spoken, kindly disposed young man, without a trace of initiative. He has tried very hard to be a real boy, but confides that he cannot and the attempt has caused him a great deal of worry. Endocrine treatment was of no avail. Thousands of dollars have been wasted on him to date. The mother was forty-eight years old when the boy was born, and the father, fifty. Case 3.—A young man of twenty years is still in school preparing for college. The writer has known this boy since he was an infant, and has exerted all possible influence to have the boy give up the college idea and go into business. His friends are all in college and there only will he be happy. He enjoys fairly good health, but has never been known to take part in any sport. He prefers to be a spectator. Exertion makes him nervous and any unusual event causes him to remain in bed the next day. He is totally devoid of initiative. He is very intelligent and most ambitious until he starts to do some thing that requires effort and then he falls “flat.” The mother of the boy is a habitual invalid, but is never very ill. The father is an unusually able busi- ness man. Case 4-—A girl, eighteen years of age, large, well-formed and mentally alert, is in school about half the time. She has frequent headaches and backaches and tires easily. Other girls make her nervous. Parties tire her. An evening of dancing could not be considered. The girl is normal physically and has been examined and treated by a goodly number of physicians, with gland therapy and otherwise. The writer has known her since she was two years old. She always has been, and always will be, useless at any undertaking that requires effort. These few cases are given simply as illustrative of the type. Similar cases and others less pronounced exist in all communities, and all have one feature in common—a lessened capacity. Rest cures, change of clim- ate, and various supporting measures are of little avail. As these indi- viduals are fashioned, so they remain; a most discouraging group. The poor individual exists throughout the entire animal world. Among the lower animals, those of defective capacity, for economic reasons, usually have a short career. The defectively functionating human, if well-born, is urged and forced and stimulated to accomplish that which is not in him. It is impossible to get out of any piece of machinery, work which the machine was not intended to accomplish. Millions of dollars are wasted on youths who are physically and mentally unable to meet the standard set up by ambitious parents and friends, in an effort toward their so-called higher education. The highly trained teaching talent of our preparatory schools and universities is wasted in part on poor student material, 25 to 50 per cent, of which should be scrapped and put to pro- ductive occupation. Before a boy is permitted to avail himself of unusual educational advantages it should be determined that he is worth it. The high school and the preparatory school should serve as a clearing house. In addition to the examination attainments required for a college entrance it should be required that a candidate submit testimonials as to physical fitness and mental capabilities from the head master or high school prin- cipal. What is needed, for economic reasons, is expert occupational diag- nosis by men who will aid in placing the boys at work to which they are fitted. 814 THE PRACTICE OF PEDIATRICS The writer has had the opportunity to keep in touch with a great many boy patients through manifesting an interest in them, and has been able to advise and assist them along occupational lines. A boy who belongs in the class we are discussing should discontinue school in the fifteenth or sixteenth year and take up business. In order to permit of a reasonable success, the occupation must be one that is not strenuous. Such boys often make fairly good salesmen, clerks, and bookkeepers. They never get very far, however, as they belong to that considerable class who watch the clock. Advancement in salary, partnership and other promotions go elsewhere. It is exceptional to find children of this type the offspring of strong, vigorous young persons. In a great majority of the cases they are the offspring of weakly mothers, the women of little resistance and of lessened endurance capacity. A strong vigorous mother will do much to offset the unfavorable influence on the progeny of a weakly male. The progeny of vigorous males is, on the other hand, greatly handicapped by inferior mothers—all of which applies to the lower animals as well as the human individual. Frequent child-bearing has apparently been a factor in some instances. By far the chief cause, however, for the “50 to 75 per cent, individual” is a mother of lowered resistance, of inherent weakened constitution, and inability for sustained effort—which defects she transmits to her off- spring. The need for a great deal of attention to the physical development of those who will some day be mothers is very urgent. Comment.—There are constitutionally inferior “substandard” (Mac- Farlane) children. Thus constituted, they enter the world and thus they continue throughout perhaps a long life regardless of attempts at improve- ment. A trait common to all is inability for sustained effort. Physicians, educators, and all others interested in the development of the young should appreciate that what often passes for indifference, indolence, and inattention may be of constitutional origin and impossible of correction. When such is found to be the case, the child’s curriculum should be made to fit the child ; and not the child to fit any “cut-and-dried” curriculum. All attempts of the latter class mean wasted energy. ANAPHYLAXIS The second introduction of a soluble foreign protein at an appro- priate interval after the first introduction of that same protein causes a train of symptoms designated by the term “anaphylaxis.” The first dose sensitizes the organism, while the second dose intoxicates. The time required for sensitization may be ten days or longer, and its duration has been found to be as long as seven years. The therapeutic use of immune sera, the majority of which are de- rived from horses, gave rise to anaphylactic phenomena which von Pir- quet and Schick recognized and called serum disease. Some patients react after a first dose of serum, the symptoms appearing eight or ten days after its injection, and consisting of fever, skin eruptions, muscle and joint pains, and glandular swellings. Such patients, after the ad- NEW GROWTHS 815 ministration of a second dose, develop symptoms after a few hours or only after several days. The immediate reaction is characterized by a local edema at the site of the injection, increasing slowly for twenty-four hours, and then disappearing in two to five days. Fever and skin eruptions are also present, and in a small percentage of cases nausea, vomiting, and even collapse may occur. When the symptoms are delayed for several days, they usually occur suddenly and disappear within a day. They are similar to those following the injection of the first dose of serum. In individuals who are asthmatic or afflicted with an idiosyncrasy to the odor of horses, a first dose of horse-serum may cause an attack of respiratory distress with cyanosis, or else cardiac weakness with a fatal ending. In such cases we must assume that the sensitization was either inherited or acquired through the lungs or through the stomach. Experimental data support all three assumptions. The tuberculin reaction is a local anaphylaxis in individuals sensi- tized to the proteins of the tubercle bacillus. Hay-fever is a local anaphylaxis to the protein constituent of cer- tain pollens. Drug and food idiosyncrasies are anaphylactic in character. Allergy to Cow’s Milk.—It is probable that the future will disclose that our trouble in cow’s milk feeding is dependent in greater or less degree upon a sensitization to cow’s milk protein. Several years ago the senior author nearly killed a baby in his office by placing on his tongue 5 drops of cow’s milk. When reactions of such severity occur and wrhen the skin of an infant reacts to an infinitesimal amount of cow’s milk protein by the formation of a large wheal it is fair to assume that there are numerous other cases of susceptibility to the foreign protein in which the allergy, although less pronounced and perhaps not easily demonstrable, is still an important factor. We are still on the threshold of knowledge of a vast number of cell reactions to foreign substances. When fresh cow’s milk disagrees we substitute usually a cow’s milk product which has been subjected to heat or drying. Thus, evaporated milk and dried milk have been used for years in feeding infants for whom fresh milk proved intolerable. The explana- tion of the success achieved in such cases lies in the fact that through the use of heat, drying, and other processes the particular toxic element in the protein in question has been changed or destroyed so as to remove its power for harm. NEW GROWTHS Carcinoma in children is of very unusual occurrence. We have seen but one case of carcinoma in a child. The lung was the site of the growth. Phillipp collected 390 cases of carcinoma reported in children under fifteen years. Among these he found but 87 which were undoubtedly true cancers. To these he added 6 cases, making 93 cases of cancer in child- hood. This report was published in 1907. In 1911 Ribbert stated that no other cases had come under his notice, so that about 93 cases of cancer (real) had then been reported in children. Three-fourths of these occurred in older children, between eight and fifteen years of age; only one-fourth prior to eight years. 816 THE PRACTICE OF PEDIATRICS The incidence of sarcoma for comparison is not given. Chondroma.—Cartilaginous tumors are occasionally observed at the adolescent period, with an origin apparently dependent in some instances on heredity, and in others, on early rachitic changes. The epiphyses af- ford favorite sites. Osteoma.—Bony growths are not infrequent in the cranial bones, at times arising from the orbit. A congenital origin is to be considered. Angioma.—This neoplasm is exemplified by the various forms of vas- cular nevi. (See p. 657.) These tumors may arise in embryonal fissures or in proximity to nerve trunks. Traumatic origin has been occasionally remarked. Sarcoma.—Various forms of sarcomata occur in childhood, those of bone being probably the more frequent. In some instances trauma is undoubtedly the exciting cause. Metastases which may involve the lung are to be expected, depending on the exact morphology of the primary growth. This, when possible, should be determined by microscopic examination of an excised section of tissue. Illustrative Case.—A fatal outcome in a case of a rapidly growing bone sarcoma of the scapula in a boy of nine years was postponed, with an apparent period of tem- porary improvement, through the persistent and intensive use of radium. The disease terminated fatally in a period of approximately two years. Lymphoma and Lymphosarcoma.—Various tumors of lymphoid tissue are well recognized in childhood and are to be differentiated from certain types of Hodgkin’s disease exhibiting sarcomatous characteristics (e. g., lymphosarcoma of the thymus), syphilitic and tuberculous adenitis, and the leukemias. Ewing1 has noted that lymphosarcoma cases may show only a moderate degree of illness until shortly before death, while the cachexia of Hodgkin’s disease is apparent over a long period. The struc- ture of an affected gland determined by its excision and examination microscopically affords accurate diagnosis. Tumors of the Brain.—Of these the cerebellar growths appear to be relatively the more frequent in children. Glioma, endothelioma, and sarcoma are the more common types. Glioma of the retina, which may be bilateral, occurs in two-thirds of the cases before the fourth year (Ewing). Embryonal Sarcoma of the Kidney.—This well-recognized malignant growth is rare except in the first few years of life, the majority of cases terminating fatally before the age of three years. The growth is typically of a complex structure described by the term “adenomyosarcoma,” and may attain such a size as to fill the entire abdomen. Hypernephroma.—The occasional presence of embryonic adrenal rests in the kidney explains the origin of this growth in which there is a resemblance of structure to that of the adrenal in distinction from that of the kidney. Tumors of the Adrenal, Pituitary, and Pineal Glands.—Reference to this subject has been made in the section on Diseases of. the Glandular System (pp. 475-477). 1 Neoplastic Diseases, 1922, p. 381. FOREIGN BODIES 817 FOREIGN BODIES From the fifteenth month to the sixth year is the period of life of humans when their desire for a close association with all sorts of objects is most prominent. This period covers the superinquisitive age. The child must handle things and manipulate every object he can get his hands on in every possible way. After he has satisfied himself in this respect he does not always know how to dispose of the articles. If these are small enough a few prominent and readily accessible openings in his anatomy appeal to him and become the resting places for a vast variety of objects. These selected repositories for foreign bodies are the nose, ears, and mouth. Foreign Bodies in the Nose.—The favored article here is a shoe button, next in order are beads, and then follow kernels of corn, peas, beans, pieces of cork, and of coal, wads of absorbent cotton, and live bugs. We have repeatedly removed articles belonging to the above group from the nostrils and ears of young children. Country children waddling through the potato patch are particularly attracted by the green potato bug. Two such were recently removed from the nostrils of respective children. The remains of a dead cockroach were not long since removed from a child’s ear. In some cases the discomfort occasioned by a foreign body will be com- plained of and the child then comes with the ready-made diagnosis. In other instances, and perhaps more often, the presence of a foreign body in the nose will be suggested by unilateral nasal discharge, more or less profuse, usually purulent, and perhaps blood stained. This usually means one of two conditions, an infection with the Klebs-Loffler bacillus or the presence of a foreign body. A probe slightly curved readily determines whether a foreign body is present. A culture in cases of doubt settles the question of diphtheria. If a foreign body is located it is best removed by wrapping the child in a sheet, binding the arms closely to the sides. Held by an attendant, the child then rests on his back with his head between the knees of the physician, with face upward. This procedure permits the best position for removal of the object, either with a small forceps or a probe slightly curved at the distal end. This is passed after the manner of the obstetrician in introducing the first blade of the forceps, along the side of, and then around, the object. In cases in which the foreign body is firmly wedged an anesthetic will be required. Foreign bodies in the oral cavity are usually readily removed with small thumb forceps. A solution of 5 per cent, bicarbonate of soda is useful for purposes of cleanliness after the removal of a foreign body. The Mouth as a Repository.—When a small object is placed in the mouth it is sometimes coughed out and at other times is swallowed and passes into the stomach. Instead it may be aspirated into the larynx, where it becomes lodged or whence it passes through into the trachea or bronchi. The accompanying cut (Fig. 145) demonstrates the possible dangers of swallowing foreign objects. A small watch disappeared from the neck of a girl four years of age. Because of the belief that it was swallowed, the stools were examined daily. The 818 THE PRACTICE OF PEDIATRICS child took the usual diet without inconvenience, and it was assumed that the watch had passed into the stomach. After five days it was decided to locate the watch or at least determine if it was in the child’s digestive tract. An x-ray examination lo- cated the object as shown. A surprising feature in this case was the passage of the food alongside the watch. Without the x-ray the case would probably have been fatal, through the formation of a perforating ulcer of the esophagus. The patient was placed on her back with the head over the side of a table, to put the mouth and esophagus on Fig. 145.—Small watch in the esophagus. a plane. By means of a “penny-catcher” Dr. Robert Abbe, with some difficulty, succeeded in removing the watch. Foreign Bodies in the Stomach.—Here again the variety is legion. Illustrative Cases.—Within the past year two children have swallowed and passed open safety-pins. A baby six months old swallowed an open safety-pin. The mother was not aware of this fact until she found the pin obstructing the anal outlet. A fifteen-months-old boy swallowed an open safety-pin of medium size during the last week of July. An x-ray of the chest and abdomen failed to reveal the pin. In October the mother brought the pin to the junior author’s office with the explanation that it had only then been passed from the bowel. Investigation disclosed that the x-ray had been taken so as to reveal nothing above the suprasternal fossa and that on the occasion of the examination, the pin was probably lodged at the level of the cricoid cartilage, a favorite site for such obstruction. At the time of this writing a child is under observation who has had in his stomach an open pin, revealed by the x-ray, for the period of four weeks. We have had children who fed on their own hair and such articles as woolen blankets. In such instances the foreign material is usually passed in balls. It is surprising what large and apparently dangerous objects will pass through the entire gastro-intestinal tract without harm. The danger lies in the object becoming fastened in some portion of the intestine and thereby producing ulceration and perforation. Active laxatives should not be employed in treating children who have swallowed foreign bodies. Milk, bread-stuffs, and cereal foods that will make a large fecal mass should be given with the hope of carrying along the object. The z-ray should be used, repeatedly if necessary, in all cases in which there is a delay in the expulsion. Foreign Bodies in the Air-passages.—Foreign bodies are usually lodged FOREIGN BODIES 819 in the larynx by an act of sudden inspiration attended by a quick, forward movement of the head, as in coughing or laughing with the object in the mouth or between the teeth. It is customary to describe the invasion of a foreign body into the larynx as accompanied by strangulation, coughing, and choking of a severe char- acter. This has been disputed by Chevalier Jackson who emphasizes the point that while such symptoms may be present there are a very considerable number of cases in which no laryngeal symptoms are noticed at any time, the foreign bodies passing through the larynx so quickly as to cause no irritation. Jackson has recited the case of a girl eleven years old in whom a piece of rabbit bone 14 x 21 mm. was lodged in the larynx for eighteen months without producing sufficient reaction to completely cut off the air-supply. Inversion of the patient has been of no service whatever in our expe- rience. The first procedure is to introduce into the mouth the index- finger, with the hope that a portion of the mass may protrude sufficiently to make possible its removal. Should the attempt fail, a laryngeal forceps should be brought into use, its introduction being guided and guarded by the index-finger. When this is not successful, tracheotomy may be required to relieve the child from immediate danger of suffocation, after which further surgical procedures may be considered. Sudden and paroxysmal cough, dyspnea, cyanosis, and hemoptysis have all been explained by the presence of foreign bodies in the bronchi. Bronchopneumonia and pulmonary tuberculosis have been the conditions early diagnosed in repeated cases of lung involvement later proved to be due to the presence in the bronchi of foreign bodies, many of which had been retained for months and years. The x-ray should be employed upon all manifestations of abnormal con- ditions within the respiratory tract. For a detailed and authentic study of this subject the reader is referred to Jackson’s contribution.1 1 Amer. Jour. Med. Sci., May, 1921. XXIII. SPECIAL DIAGNOSTIC METHODS So manifold are the special tests now available for completing and confirming ordinary physical diagnosis that more than a cursory survey of the special methods is here impracticable. Among the materials com- monly sent to the laboratory for examination are blood, urine, stools, breast milk, gastric contents, sputum, cerebrospinal fluid, various exu- dates and transudates, conjunctival and vaginal discharges, and cultures from the throat. Blood must be obtained in many cases not only for the routine cell count, but for culture, Widal test, the Wassermann test, and detailed blood chemistry study. It is essential that the physician be at all times prepared to obtain promptly any specimen indicated in a given case. For example, Streptococcus viridans growth may be apparent in a blood- culture only after the lapse of several days or even a week, so that the time element is readily seen to be of great importance in prompt diagnosis. Urine may be obtained from young infants by means of the Spicer urinal, the Chapin urinal, or one of the many test-tube devices kept applied to the urethral orifice. Catheterization is seldom essential in obtaining urine for ordinary culture, provided aseptic precautions are observed in collecting the specimen. Catheterization of the female ureters may be satisfactorily done at an early age by one who is skilled in the technic. Sputum, even in the presence of a productive cough, is not readily ob- tained from young children because of their failure and apparent inca- pacity to expectorate. The insertion of a catheter into the throat will often induce coughing of sufficient degree to lodge upon the catheter material suitable for microscopic study. The ophthalmoscope is available not only for routine eye tests but for detection of nephritis, amaurotic idiocy, and intracranial lesions includ- ing tuberculous meningitis and brain tumor. The laryngoscope and bronchoscope are invaluable in the recognition of various forms of respiratory obstruction and in revealing localized ulcerations. These instruments have been employed with most gratify- ing success in the removal of foreign bodies from the air-passages. The esophagoscope has a similar range of application. Fluoroscopy is of signal value in the study of the chest and abdomen. This means of confirming the findings of ordinary physical examination is extremely satisfactory, and its range of applicability includes the ob- servation of the gastric and intestinal activity and the recognition of abnormalities, among which should not be forgotten diaphragmatic hernia. The x-ray is available for countless purposes, ranging from the study of pathologic changes within the thorax to the study of rachitic bones and the localization of foreign bodies in the respiratorv tract or the ali- mentary tract. Study of the electric reactions is of value, not only in estimating the significance and degree of various paralyses but also in the recognition 820 SPECIAL DIAGNOSTIC METHODS 821 of latent tetany and in the diagnosis of obscure and unusual neurologic disorders, e. g., amyotonia congenita. Gastric analysis, although less relied upon than formerly, is of value to the pediatrist, provided minor variations in chemistry are disregarded. Incidentally the permeability of the esophagus is readily ascertained on passing the stomach-tube. Duodenal catheterization employed for aspiration of duodenal contents is similarly of definite aid in determining the permeability of the pylorus. Pleural Puncture (Thoracentesis).—The point of election for this pro- cedure which is often demanded by the diagnosis of a fluid effusion in the pleural cavity is the seventh or eighth intercostal space in the mid- axillary line. The patient lies on the unaffected side with the shoulders elevated by pillows, and the arm on the affected side drawn forward and upward. The aspirating needle, which should be of good strength and caliber, should be introduced in the interspace just above the costal border, with a sharp thrust, to a depth of an inch or more, when it may be detected that the point of the needle is in a free cavity. Aspiration should be performed very gradually and stopped on the occurrence of coughing. Pericardial Puncture.—This may be urgently required in the presence of traumatic hemopericardium and pericarditis with effusion, not only to corroborate diagnosis but as a life-saving measure. The puncture should be made at the site of a small preliminary incision, with a needle or fine cannula and trocar fitted to an aspirating apparatus. The point of election is in the fifth intercostal space close to the left sternal border. From this point the needle should be directed obliquely down- ward and inward. By Dieulafoy’s method the puncture is made in the fifth space 4 fingerbreadths from the sternum through a short vertical preliminary incision. The needle is cautiously pushed obliquely inward from this point almost parallel to the plane of the chest wall. Peritoneal Puncture.—This procedure is of comparatively recent de- velopment and should never be employed indiscriminately. The needle may be inserted as in making an intraperitoneal injection at a point about 2 inches below the umbilicus. (See p. 850.) The needle should be directed carefully inward and upward until it enters the peritoneal cavity. The indications for exploratory puncture of the pleural, pericardial, peritoneal, and joint cavities are generally appreciated. As a fixed prin- ciple, one should refrain from any purely diagnostic step involving the intro- duction of a needle into a cavity normally sterile, until all ordinary means of arriving at accurate recognition of the existing diseased condition have been exhausted. Lumbar Puncture.—The site selected for lumbar puncture is on a line between the crests of the ilia and between the spinous processes of the third and fourth lumbar vertebrae. Position of the Patient.—The child should rest on one side (Fig. 147), sufficient pressure being exerted on the buttocks to make the spinous processes prominent. The Quincke needle (Fig. 146) should always be used in making the puncture. The stylet which fits the beveled edge of the point of the needle effectually prevents its being plugged. Method.—The skin for several inches about the site of the puncture 822 THE PRACTICE OF PEDIATRICS should be scrubbed with tincture of green soap and alcohol. The phys- ician’s hands should be thoroughly disinfected. Considerable force may be necessary in order to enter the canal. When there is a sudden giving way of the obstruction to the progress of the needle, one may know that the canal has been entered. The puncture may be made in a line with the spinous processes or from the side, the needle being passed between the laminae and inward about 1 inch. When the point of the needle has been introduced into the spinal canal, the stylet is with- Fig. 146.—Quincke’s needle. drawn. The cerebrospinal fluid may escape with force in a stream as a result of the pressure or it may exude drop by drop. A sterile tube should be in readiness in order to collect the fluid for examination. In dealing with older children after the third year it is often easier to introduce the needle slightly to the right or left of the line of the spinous processes. When the canal is entered and the cerebrospinal fluid does not pass readily through the needle, the flow may be increased by elevating the child almost into a sitting position with the head forward. A dry tap Fig. 147.—Position for and site of lumbar puncture. usually means that the canal has not been entered. For some children it will be necessary to employ a slight degree of anesthesia. Gas or chloro- form may be employed for this purpose. Uses.—The uses of lumbar puncture are threefold: for diagnostic purposes, as a means of conveyance of sera to the spinal canal, and for the relief of acute pressure symptoms by the withdrawal of the fluid. Ventricular puncture should be performed only in the event of apparent blocking of the cerebrospinal fluid channel at the base of the brain (as determined by examination including previous lumbar puncture), and is SPECIAL DIAGNOSTIC METHODS 823 applicable only exceptionally after the age when closure of the anterior fontanel is completed. The head should be shaved and aseptically cleansed. With the patient in the recumbent position the needle is inserted through the anterior fontanel a little less than 1 cm. to one side of the midline and is directed forward and slightly downward to a depth of not over 1| inches. The introduction of air or phenolphthalein into the ventricle is oc- casionally resorted to in the differentiation of the exact character of a hydrocephalus. Cisterna puncture is occasionally employed, when the spinal and ven- tricular taps are found impracticable, for the withdrawal of fluid or the injection of serum. The needle is introduced for about 4 cm. in the mid- line just above the spine of the axis on a plane traversing the glabella and the upper margin of the external auditory meatus. The Widal Reaction for Typhoid Fever.—To make Widal tests it is necessary to keep in stock a well-agglutinating strain of typhoid bacillus. A bouillon or agar culture which has grown not longer than eighteen to twenty hours should be used for the reaction. The blood to be tested should be obtained in a small glass tube of the Wright pattern, 0.5 to 1 c.c. in amount, sealed at both ends, and the serum allowed to separate. Sterile physiologic salt solution is used as the diluent. A porcelain palet with six or more cup-like depressions is a convenient receptacle for holding the dilutions, if the microscopic method is used. By means of a capillary tube marked by a wax pencil 1 drop of serum and 9 drops of salt solution are mixed in one of the palet cups, making a dilution of 1 : 10. From this stock other dilutions are made; 1 drop to 4 of salt solution equals a dilution of 1 : 50, etc. The addition of 1 drop of culture to 1 drop of a 1 : 10 dilution of serum makes a dilution of 1 : 20. This is examined on a hollow slide with a No. 7 lens. Con- trols of the culture alone, and of culture plus normal serum should be made at the same time. Cessation of motion and clumping of the bacilli within one-half to one hour, in a dilution of 1 : 40, constitutes definite proof of typhoid infection. The microscopic method should be employed by preference. By the macroscopic method dilutions are made in small test-tubes. The tubes are placed in the incubator at 37.5° C. for one hour and then in the ice-chest overnight. The reaction can be read at a glance. The clumped bacilli fall to the bottom of the tube and leave the serum quite clear, while the control remains turbid and smooth. The quantity of serum required is very small, 0.2 cm. being sufficient to make all neces- sary dilutions. Each tube may contain 0.8 cm. of diluted serum and 0.2 cm. of bacillary suspension, making a total of 1 cm. Agglutination in a dilution of 1 : 40 may be looked upon as a positive reaction. With blood dried on a slide the test cannot be accurately made. Cul- tures of typhoid bacilli killed with formalin have been used for making the Widal test, but the method has nothing to recommend it. The Widal reaction does not given positive results before the end of the first week or the beginning of the second week of typhoid. It may continue to be positive throughout convalescence and for an indefinite period thereafter. Occasionally its appearance is deferred until conva- 824 THE PRACTICE OF PEDIATRICS lescence or until a relapse comes on, but it is present at some time during an attack of typhoid fever in over 95 per cent, of all cases. Tests for Tuberculosis.—Tuberculin is used as a diagnostic agent to detect early, latent, or doubtful cases of tuberculosis. Different methods have been employed in the application of tuberculin. Subcutaneous Inoculation.—The dose used for diagnosis is larger than that allowable for immunization purposes, from 1/10 to 5 or 10 milligrams being used, according to the age of the child. If the patient is tuberculous, the injection is followed in eight to twenty-four hours by a rise of temperature, a certain amount of malaise, tenderness at the site of injection, and rales over the suspected lung area. The re- action is general as well as local. The temperature falls within twenty- four hours. No reaction occurs in non-tuberculous cases, while in 95 per cent, of those of tuberculosis the test is followed by a positive re- action. Absolute exclusion of tuberculosis, however, because of a neg- ative result, is not possible. The test is applicable only to cases which do not run a temperature over 37.7° C. (100° F.), and is useful in doubt- ful and obscure cases. It may be necessary to repeat the inoculations two or three times before a positive reaction occurs; the initial small dose of 1/10 milligram being followed in three days by another of 1 milligram, and again, if necessary, in three days by another of 3 or 5 milligrams in older children. A second subcutaneous test is the puncture or stick reaction of Ham- burger. In older children 1/1000 to 1/100 milligram of tuberculin is injected just beneath the skin. Within twenty-four hours the local re- action begins and lasts for five or six days. The redness and induration are visible at the point entered by the needle, and also at the place where the injected fluid is deposited. Cutaneous Inoculation.—This method of vaccination with tubercu- lin was introduced by von Pirquet. A small superficial scarification is made on the forearm, and a drop of undiluted tuberculin is applied. An untreated scarified area of equal size is made at the same time for control purposes. In cases of active tuberculosis the reaction begins within twenty-four hours. A small red papule forms, surrounded by a limited area of redness and induration. In four to eight days the nodule has disappeared. The control scarification heals without any inflam- matory sign. Yon Pirquet himself uses a fine boring instrument instead of scarifying. The method is most valuable in infants and children under two years of age. A positive reaction is accepted by von Pirquet as proof positive of tuberculosis. A negative reaction, on the whole, means absence of any tuberculous focus. In the last days of a miliary tuberculosis the reaction fails to appear in about half the cases. Furthermore, in cachectic conditions from any cause the reaction does not appear. During the eruptive stage of measles it is absent in 100 per cent, of tuberculous cases, while in scarlet fever the negative result is less constant, the reaction failing to appear in 85 per cent, of the cases. After the eruption has disappeared a von Pirquet reaction may be obtained. Tuberculous patients suffering from diphtheria or typhoid fever also fail in some instances to react to the cutaneous tuberculin test. SPECIAL DIAGNOSTIC METHODS 825 Differential Cutaneous Reaction.—Detre devised this method of diag- nosing human from bovine tuberculous infection. He used the filtrates of bouillon cultures of human and bovine tubercle bacilli, applying them by the von Pirquet cutaneous method, making the scarifications and the applied drop of fluid as nearly alike as possible. The diagnosis is de- termined by the relative size of the resulting reaction papules, which Detre carefully measures. Thus far, most observers find that in the major- ity of cases the two reactions are equally marked, and it has not yet been established that the differential diagnosis between human and bovine tubercle bacillus infection is possible by this means. The Moro Inunction Test.—Equal parts of old tuberculin and anhy- drous lanolin are used in the form of a salve. The dose is about 1 gram of the ointment, rubbed into an area of healthy skin about 5 cm. in diam- eter. The application is made in the epigastric or submammary region, a rubber finger-cot or glove being used to rub the ointment into the skin for three-fourths of a minute or more. The inoculated area is exposed to the air for ten to twenty minutes, and no dressing is applied. It is well to clean the site of the inunction with alcohol before applying the salve, and also to ring the inoculated area. A control with plain lanolin is to be made on another part of the skin. The reaction manifests itself in ten to seventy-two hours, but in the majority of cases it does not appear later than the second day. The eruption which appears is papulovesicular in character, with an erythematous areola around the individual papules. In a severe reaction the areolae may coalesce. The papules vary in number from very few (1 to 4) to very many (50 to 100). Itching sometimes occurs. The eruption persists for several days; in severe cases it may be appar- ent for seven to ten days, and may be followed by pigmentation and desquamation. The test is simple and harmless. As a rule, the von Pirquet reaction is fully developed several hours before the inunction (Moro) reaction. Ophthalmo-reaction.—This was first described by Wolff-Eisner and shortly afterward by Calmette. It consists in the instillation of 1 drop of 0.5 per cent, solution of tuberculin into the conjunctival sac of the healthy eye of the patient. Within twelve hours swelling and redness are at their height, and gradually subside in twelve hours more. The advantage of the cutaneous method over the subcutaneous is that the former obviates the possibility of spreading the tuberculosis, since no general reaction follows the application. Both methods are based upon the principle that in the course of a tuberculous infection all the cells of the body are sensitized to the products of the tubercle bacillus. When, therefore, a minute quantity of such products (tuber- culin) is brought into direct contact with a sensitized and vascular tissue, like the skin.or conjunctiva, a rapid inflammatory response occurs. The Mantoux or Intradermal Test.—For routine use this test is the most reliable of all. The reasons for choosing this method, with a descrip- tion of the technic have been given in a review by Smith.1 “The subcutaneous general febrile reaction is not in general use, and is somewhat dangerous in childhood; the Calmette and Moro have been 1 Charles Hendee Smith, Tuberculosis in Childhood, Bulletin of New York Tuber- culosis Association, 1923. 826 THE PRACTICE OF PEDIATRICS practically abandoned. Those in common use are the Pirquet or epider- mal, and the Mantoux or intradermal reactions. “We have found at Bellevue Hospital that the intradermal is at least twice as accurate as the Pirquet, and has the single disadvantage that the dilute solution must be prepared. It is very simple, however, to prepare. “For a 1 : 1000 dilution, put 1/10 c.c. of old tuberculin in 100 c.c. of salt solution. (This can be rapidly done by any one with boiled water and a salt tablet.) Dose: 1/20 c.c. or 1/20 mg. for infants (0.00005 gm.) and 1/10 c.c. or 1/10 mg. for older children (0.0001 gm.). “These amounts are injected into the skin not under it (just as in the Schick test). If negative, in suspicious cases a larger dose may be used, up to 4/10 or 6/10 mg., taking care not to increase too rapidly in order to avoid a general reaction. The reaction is easy to read, safe and ac- curate, and if positive gives a much larger erythema than the Pirquet. It should be read daily for five days, or if only once, on the second or third day. “The Pirquet is slightly easier to do, but gives us only about half as many positive reactions, due to unavoidable sources of error intrinsic to the reaction, even when done with the greatest care.” The study of a large series of cases with the aid of the intradermal test at Bellevue has shown that not over 40 per cent, of children there examined are infected at puberty. This percentage is lower than that for any previous series reported in this country. (See Fig. 135, p. 767.) The Schick Test for Susceptibility to Diphtheria.—This reaction and its range of application have been previously discussed (pp. 688-690). The Dick test for susceptibility to scarlet fever has also received men- tion (p. 704). The Wassermann Test for Syphilis.—The Wassermann reaction is the application of the complement fixation or deviation test to the diagnosis of syphilis. As introduced by Wassermann, Neisser, and Brack it re- quired the use of guinea-pig complement, the serum to be tested, antigen consisting of extract of syphilitic liver, and a sheep’s hemolytic system. By sheep hemolytic system is meant an immune rabbit serum prepared by inoculating rabbits with washed sheep’s erythrocytes, and a sus- pension of washed red blood-cells of the sheep. In the presence of fresh guinea-pig serum (complement) such an immune serum has the power of hemolyzing the red blood-cells. In the same way human hemolytic system means the combination of washed human erythrocytes and an immune serum prepared by inoculating rabbits with washed red blood- cells of the human type. If the serum to be tested contains immune bodies specific to the anti- gen used, these will, in the presence of complement, unite with each other and bind the complement. The addition of the hemolytic sys- tem will then cause no change in the tubes, i. e., hemolysis will not occur. If the antigen and the immune serum are not specific, then the com- plement is left free to unite with the hemolytic system and hemolysis occurs. This is called the complement fixation or deviation test. As simplified by Noguchi, the test requires much smaller quantities of guinea-pig complement, the serum to be tested, antigen consisting of human or animal tissue extract, and human hemolytic system. For SPECIAL DIAGNOSTIC METHODS 827 practical purposes 1 c.c. of the patient’s blood will give an ample amount of serum for the test. The Wassermann seroreaction is positive in 98 per cent, of cases of congenital syphilis, but only in 66 per cent, of latent syphilis. During the primary stage of acquired syphilis 90 per cent, of the cases give a positive Wassermann test, during the secondary stage, 96 per cent.; and during the tertiary stage, 83 per cent, react positively. Craig has found that the reaction may disappear from two to four weeks after the institution of mercurial treatment, but it may return when the treatment is stopped; therefore it is not established that the disappearance of the reaction justifies the conclusion that the disease has been cured, and that treatment may be discontinued. Noguchi found that after treatment with salvarsan the reaction may disappear within two weeks in promptly cured cases, although it may not do so for four or five weeks. The spinal fluid Wassermann reaction is employed in the diagnosis of neurosyphilis. This test may be positive in the presence of juvenile tabes or paresis even when the blood Wassermann reaction in the patient is negative. The Noguchi Butyric Acid Test.—This test is based upon the fact that the globulin reaction in the blood-serum and in the cerebrospinal fluid is increased in syphilis. In the case of the blood-serum the test is too complicated to be used anywhere except in a highly equipped laboratory and, moreover, it is not needed in children, since Wassermann’s serum re- action answers all practical purposes. Applied to the cerebrospinal fluid, the Noguchi test is very simple and is carried out as follows: 1/10 or 2/10 c.c. of cerebrospinal fluid, which must be absolutely free from blood, is mixed with 1/2 c.c. of a 10 per cent, solution of butyric acid in normal saline and boiled. Then 1/10 c.c. of normal sodium hydroxid solution is quickly added, and the whole is boiled for a few seconds. A granular or fioccular precipitate indicates a positive reaction. The appearance of the precipitate within a few minutes indicates a considerable increase in globulin, while weaker reactions may not appear for an hour. Two hours should be the time limit. Normal cerebrospinal fluid with this test gives a slight opalescence and occasionally turbidity, but the granular precipitate does not occur at all or only after the time limit has been reached. A positive reaction occurs with the cerebrospinal fluid from any case of syphilitic or parasyphilitic affection, and also in all acute inflamma- tions of the meninges, whether due to the meningococcus, the tubercle bacillus, the pneumococcus, the streptococcus, or the influenza bacillus. The reaction is also positive in the early stage of poliomyelitis. Such conditions can, of course, be readily differentiated from syphilis. In acute luetic meningitis the presence of Treponema pallidum in the cere- brospinal fluid will serve to exclude the other forms of meningitis. Such a case has been reported by Rach1 in a child four months old. In hydro- cephalus the cerebrospinal fluid gives a positive butyric acid test in cases which are of syphilitic origin. When the amount of cerebrospinal fluid is increased without inflammation of the meninges, as sometimes 1 Jahrb. f. Kinderh., 1912. 828 THE PRACTICE OF PEDIATRICS happens in pneumonia, the fluid does not give a positive butyric acid test. In children Noguchi’s test is most valuable in differentiating be- tween inflammatory and non-inflammatory conditions of the meninges. The Colloidal Gold Reaction of Lange.—This depends on the fact that normal cerebrospinal fluid when diluted with a 0.4 per cent, sodium chlorid solution does not produce color change in colloidal gold, while pathologic cerebrospinal fluid similarly treated produces distinctive changes for various diseases. This reaction is specific for syphilis ofvthe nervous system and is applicable to the diagnosis of meningitis. By means of observations on the quality of the color change produced under different dilutions of the spinal fluid typical curves are plotted significant in diagnosis of the various diseases. Tests for Renal Function—In addition to the routine urinary exam- inations customary in the general practitioner’s office various tests are invaluable for the purpose of more accurate differentiation and prognosis in cases of disease of the kidney. In an estimate of the value of kidney function Longcope1 has designated the phthalein excretion and blood chemistry findings as of value in making the prognosis in acute neph- ritis. In chronic nephritis the chlorid and nitrogen concentration partic- ularly, together with the phthalein excretion, afford information of value. Blood chemistry offers a means of differentiating uremia from other kinds of coma. The phenolsulphonephthalein test devised by Rowntree and Geraghty2 consists in the determination of the rate of excretion by the kidney of 1 c.c. of a solution containing 0.6 gram of phenolsulphonephthalein injected in the upper arm. By the normal kidney 40 to 60 per cent, of the drug is excreted in the first hour and 20 to 25 per cent, in the second hour, this excretion occuring without conformity to the rate of excretion of water. The phthalein test is most reliable in acute conditions. Two factors markedly influencing this test are the rate of absorption of the dye, de- pending on the size of the injection and the existence or non-existence of edema; and the amount of urine in the bladder, which should, of course, be empty at the time of the injection. The Mosenthal test,3 based on a modification of a test for estimating renal function, proposed by Hedinger and Schlayer4 has been simplified so that it is at present readily available in ordinary practice. With a normal diet in health the maximum specific gravity of the urine is to be regarded as 1018 or 1020 or higher, and a variation of 9 degrees between high and low specific gravity should obtain. The volume of the night urine representing the total voiding from 8 p. m. to 8 A. m., in children (depending on the age) should be 200 to 500 c.c., the total twenty-four-hour excretion being about 1 liter. The nitrogen and sodium chlorid normally constitute about 1 per cent. When renal function is impaired the quantity of night urine becomes increased and the specific gravity of the urine shows fixation which may 1 Boston Med. Surg. Jour., 189, 269, 302, August 23, 1923. 2 Jour. Phar. Exper. Therap., 1910, i, 579; Arch. Int. Med., 1912, ix, 284. 3 Arch. Int. Med., 1918, xxii, 770. 4Deutsch. Arch. f. klin. Med., 1914, cxiv, 120. SPECIAL DIAGNOSTIC METHODS 829 be at a high or low level, while the salt and nitrogen elimination is dimin- ished. Variations in degree of edema elimination are to be considered in interpreting the test, but the interpretation is not dependent, as was at first thought, upon special diet. In applying this method the urine is collected at two-hour intervals in separate containers from 8 a. m. to 8 p. m. That voided from 8 p. m. to 8 a. m., constituting the total night urine, is collected in one container. Estimations of urea and urinary nitrogenous constituents of the urine, formerly much in vogue, are of little value unless combined with a study of the food intake and the chemical content of the blood. Such tests are therefore impracticable. Blood chemistry determinations are not needed for the recognition of the existing kidney disease, but within limits are more reliable than urinary and functional tests and afford information on the following- points: (1) Whether nitrogen or salt and water elimination is defective, (2) degree of retention, (3) prognosis, and (4) trend of the disease, partic- ularly in response to treatment. In various acute infections, postoper- ative states, diarrhea, vesical calculus, and pyelitis a determination of the non-protein nitrogen and its constituents will show the degree of impair- ment of kidney function and afford warning of impending nephritis. The following figures may be taken as normal for the more important substances routinely determined in blood chemistry study: Non-protein nitrogen Milligrams per 100 c.c. 20-30 Urea nitrogen 8-15 Uric acid ‘ 1- 3 Creatinin 1- 2 Glucose 60-120 Chlorids Calcium 9-12 Phosphorus 5- 6 Cholesterol 150 Corpuscular volume 35- 45 per cent. Carbon dioxid combining power Of the non-protein nitrogen constituents creatinin, because it is or- dinarily eliminated most readily by the kidney, serves as a valuable prog- nostic indicator of the kidney capacity, creatinin retention occurring prac- tically only in nephritis. A creatinin content of over 3 mgm. is con- sidered serious and one of over 5 mgm., of fatal prognostic import.1 Uric acid is most difficult to eliminate and in acute conditions is the first constituent to show an increase. In chronic conditions there is no greater difficulty in its elimination than in that of creatinin and non-pro- tein nitrogen. Estimation of the carbon dioxid combining power of the blood, for which the Van Slyke method is replacing the alveolar air determination method, affords valuable information respecting the degree of acidosis in diabetes, intestinal intoxication, and postoperative disturbances of metabolism. The administration of insulin in diabetes should be checked by repeated blood chemistry observations of this type as well as by frequent esti- mations of blood-sugar and urinary sugar. 1 It should be noted that what is determined as creatinin may actually not be crea- tinin, but the significance of the color-producing substance remains the same. 830 THE PRACTICE OF PEDIATRICS The determination of the calcium and phosphorus content of the blood is particularly valuable in rickets and spasmophilia, although careful clinical examination will reveal rickets before it is disclosed by x-ray or blood analysis. When the x-ray shows the disease there is regularly a diminution in the phosphorus content of the blood. In active tetany the blood calcium is always low, without significant increase in the phosphorus content. In rickets complicated by tetany, however, the phosphorus is relatively high as compared with that in uncomplicated rickets. Latent tetany may be shown by low blood calcium as well as by the altered elec- tric reactions. Other tests to be kept in mind as of particular importance practically are the hemolysis and agglutination tests to determine compatibility of donor’s and recipient's blood for transfusion, the blood fragility test, invaluable in the diagnosis of hemolytic icterus, and the estimation of coagulation time and bleeding time. XXIV. THERAPEUTIC MEASURES THE FUNDAMENTALS OF THERAPEUTICS IN CHILDHOOD It has been our object, in this work, to present as clear and detailed a description of the management of the illnesses of infancy and childhood as space would permit, with a view to a better understanding of pediatric therapeutics. If asked what should be considered an important requisite for the successful practice of pediatrics, we would answer: The education of the mother. It is impossible to do even fairly good work in treating dis- eases of children without proper home co-operation. A direction is never followed out as well as when the reason for it is properly understood. Many of our beneficial results are due to the therapeutic influences of remedies outside of the realm of drugs. Thus, diet, fresh air, sunshine, cold, heat, massage, electricity, climate—all are important therapeutic agents in the diseases of children. Successful therapy applied to chil- dren requires an understanding and a knowledge of detail greater, per- haps, than for any other line of medical work. It not infrequently is an absence of such knowledge on the part of medical men, which explains a great deal of the therapeutic doubt existing at the present time. Thera- peutic nihilism, so far as pediatrics is concerned, means ignorance and incompetency. The time when the physician can make a diagnosis and cease from interest in the treatment of the case is past. The faith of humanity in curative agents is remarkable, and when the desired end is not reached by the first physician, some other physician is called; and when he fails, the next resort usually is the charlatan or the proprietary med- icine. The prosperity of the irregular schools of various cults and “sciences” supposedly healing in character, and the consumption by the people of millions of dollars’ worth of useless patent drugs, are to be attributed in a large degree to an indifferent application of therapeutic measures on the part of otherwise well-qualified medical men. A few great teachers of medicine, by precept and example, have done an incalculable amount of harm in their attitude toward therapeutics. Because they were, or are, unable successfully to treat disease, they assume that it cannot be done. Thus, therapeutic doubt has been in the past boasted of by men considered clever. Text-books on pediatrics are not without fault in encouraging careless practice, with necessarily an absence of favorable results, especially when they state that “treatment is along supportive lines.” What constitute “supportive lines” in a given case? How is the practitioner to know the author’s mind? Or, again, perhaps it is stated that “free stimulation” is necessary. Stimulation how, when, why, and by what means is what must be known, in order to achieve satisfactory results. “Treatment according to the indications of the case” does not help a puzzled physician to any great extent. “Treatment along the same lines as in adults” adds no illumination when a desperately sick child is the patient, and moreover is faulty teaching, for the reason that 831 832 THE PRACTICE OF PEDIATRICS an infant or young child should never be treated the same as an adult, either by drugs, or other means, unless we wish more thoroughly to convince ourselves of the uselessness of therapeutic measures. In order to practice therapeutics successfully with children the methods of the physician must be flexible and adaptable. Children vary in their physical and mental equipment much more than do adults. The practice of pediatrics is necessarily difficult, for every case has to be studied from its own standpoint. The physician who invariably treats all his cases alike will never do the highest class of work with children. The man, for example, who feeds all his difficult feeding cases after one rule or pat- tern will be sure to have some other practitioner get his failures, which will not be few. A source of disappointment to the physician, particularly in the treatment of young infants and children, exists in the disorders of nutrition. A tremendous amount of patience is required in dealing with such cases, and the absence of prompt results is one of the difficult features he has to contend with in his relations with the family. There is, further, a distinction to be made as to what constitute good results. If the infant develops into a strong child, we may chronicle our results as satisfactory even though a year elapses before the condition of the patient becomes satisfactory. To cause a malnutrition baby weighing only 8 pounds at six months, with marked milk incapacity, to show rapid growth by any method of artificial feeding is unusual, and results are good if he gains but little during the first few weeks. Chronic colitis, tardy malnutrition, or nephritis may require months and years for correcting and yet permit of satisfactory results. In the treatment of infants and children, particularly as regards the use of drugs, two points are to be kept in mind—the benefit hoped for and the possible harm that may result. A great deal of judgment must be used in the selection of remedies and the means of using them, lest our best intentions result to the patient. Thus, in bronchitis and in bronchopneumonia, the ammonium salts are often given in combination with heavy syrups, such as tolu and wild cherry, both possessing little or no value as expectorants, but having the prop- erty of interfering seriously with the patient’s digestion. Doubtless, alcohol used indiscriminately is, on the whole, productive of more harm than benefit, largely through disturbing the digestion. Digitalis, the salicylates, and the potassium and sodium salts are all to be used with judgment as to method and time of administration or they will do more harm than good. A point never to be lost sight of in the treatment of diseases of children is the desirability of keeping the gastro-enteric tract in the best possible condition. In the care of children there are other factors also that bear upon the case that tend toward good or evil. The most careful diet, and the best selected medication are of little value if the patient is overclad, or kept in a superheated room with anxious, distracted, nervously exhausted persons in constant attendance, with the disturbance to the patient which such attendance entails. It must be remembered that absence of proper detail and good judgment, with resulting failures, is no argument against the value of therapeutic measures. Much may be accomplished by means of prophylaxis in lowering the THE THERAPEUTIC VALUE OF CLIMATE 833 mortality" in children under five years of age. In this the educated mother’s aid is invaluable. She will lay aside prejudices and unfavorable family influences when a physician’s direction appeals to her reason. Maras- mus, malnutrition, and the intestinal diseases of summer, which directly or indirectly are the cause of thousands of deaths yearly, are to a large degree preventable if the right step is taken at the right time, through the early appreciation of danger signals, on the part of both the physician and the mother. THE THERAPEUTIC VALUE OF CLIMATE That climate is a valuable therapeutic agency in the treatment of diseases of children is a well-recognized fact. An important advantage of a change of climate is that it means more air and probably bet- ter air. When patients go to a resort for climatic benefit it is usually at no inconsiderable expense, and they are therefore pretty likely to avail themselves of advantages. The same amount of air could be fur- nished at home if the family co-operation always could be secured. By the use of the window-board, the roof-garden, and the indoor airing we can to a considerable degree make a climate of our own. Neverthe- less, in the majority of families the open-air treatment cannot be carried out successfully; therefore, the best interests of the patients are secured when they are sent away from home. There are conditions also in which such means as those just mentioned do not apply even if they are ap- preciated. We can give children warm air, and regulate the tempera- ture of the air in the winter; but if they live in any of our coast towns or villages, we cannot give them cool, dry air in summer. Children who can be removed from a large city to the country, inland, for the summer, are invariably benefited, not only as regards their food capacity and the ordinary apparent effects of open-air life, but they acquire also greater powers of resistance, and are thus less liable to acute intestinal diseases. (See Summer Resorts, p. 834.) Pneumonia, Pertussis, and Grip.—During the colder months New York City children who are convalescing from pneumonia, pertussis, or any prolonged illness which has greatly reduced them, will make a much more rapid recovery when removed to Lakewood or Atlantic City, where open-air life is more easily secured than at home. Malnutrition and Digestion Disorders.—Infants and children suf- fering from chronic digestive disorders, marasmus, and malnutrition, who are given the advantages of climate or open-air methods, either in the home (p. 838) or by a change of residence, invariably make a more rapid recovery than do those deprived of good air because of a lack of appreciation of its value, or through fear of the child’s taking cold. Nephritis.—There are diseases in children in which sudden change of temperature, affecting the peripheral circulation, may be decidedly harmful. Such variations are a menace in slow convalescence from acute nephritis, and also in chronic nephritis. Cases of this type require an equable climate, with a permissible outdoor life, such as is furnished during our colder months by Florida and Lower California. Asthma.—Experiences as to the effects of climate in asthma have been contradictory. 834 THE PRACTICE OF PEDIATRICS With our knowledge of the dependency of asthma upon protein sen- sitization, the effect of climate on this condition has been relegated to a very unimportant position. Site more than climate is a determining factor in those cases due to pollen sensitization. Centers long reputed of value in hay-fever and asthma we now know achieved their fame due to the absence of plants to which individuals were sensitized. For the so-called non-sensitized cases which follow or are dependent upon bronchitis a dry atmosphere with relatively slight humidity is of advantage. Tuberculosis.—The best winter climate for a child with pulmonary tuberculosis is a dry climate with a mild temperature, neither high nor low, but with sunshine in such abundance as to permit a daily outdoor life. Such a climate is found in southern New Mexico and Arizona. These places furnish conditions as near to the ideal as it is possible to approach. The Adirondacks, while furnishing a climate in winter which may be too severe for young children, serve well for those from eight to nine years of age in whom the disease is not far advanced. The sanitarium treatment is always to be advised if the patient can afford it, or if it is otherwise available through charity. The advantages consist in the discipline, the diet, the amount of exercise, the sleeping quarters, the clothing—in short, in all the details of the life, every one of which is important. In a sanitarium all these matters are in the hands of those who are skilled in the management of the disease, and who direct each case according to individual needs. Ordinary resorts for tuberculous cases are dangerous because of the possibilities of reinfection through the carelessness of others. In a well-managed sanitarium, however, regulations, regarding expectoration and the care of the sputum reduce this danger to a minimum. Sanitariums, however, are available to but few patients. Many have not the means necessary for change of residence, and many others refuse to allow their children to be separated from them, both of which facts necessitate the home treatment of a great majority of the cases of pulmonary tuberculosis in young children in our larger cities. (See p. 398.) SUMMER RESORTS Where to take a baby for the hot months of the year is a vexed ques- tion which is raised in many city households every year, inducing a situation in which the physician may be called upon for advice. Several years’ observation of a great many New York City children who have spent the summer out of town has led to the following con- clusions: The most desirable summer outing consists in spending the first half of the season at the seashore, the remainder inland, preferably in the mountains. The next sojourn in order of desirability is inland, preferably at the mountains, for the entire summer. The least desirable is at the seashore for the entire summer. It is not to be understood that many children will not do well if kept at the seashore throughout the hot months. Some, indeed, improve most satisfactorily, but from observing our own patients we have repeat- INSTRUCTIONS FOR THE SUMMER 835 edly been impressed with the disadvantages of a too prolonged stay at the seashore. If kept there during August, infants are apt to show signs of lassitude, and while not ill, they do not return to the city in the autumn with the vigor, appetite, and general robustness which characterize those from the hills and mountains. It must be remembered that only New York City children are referred to. Children whose home is a seaport thrive best when given the benefit of a complete change to the dry, in- vigorating air inland. Children with catarrhal tendencies, bronchitis, or adenoids (before or following operation), and children who have had attacks of rheumatism or who show rheumatic tendencies, should not go to the seashore, wherever their residence. For an inland resort, the mountains, by which we understand an elevation of 1500 to 2000 feet, are not always essential. The place selected, however, should be at an elevation at of least 600 feet. For cases of chronic bronchitis and rheu- matism a soil of sand or gravel is best, and the sleeping-room of the child should always be above the ground floor. Other points to be considered in connection with the summer outing are the kitchen facilities, which must be ample. Often the larger hotels refuse the right of way to the kitchen. In this respect much more liberty is given in the smaller hotels and boarding-houses. The proper prepara- tion of the child’s food in the cramped quarters of sleeping-rooms is not impossible, but is often difficult and always objectionable; therefore, if a cottage is available, it will be greatly to the child’s advantage. Before final selection of a home for the summer the drainage, and the source and quality of the milk supply should receive the most careful attention. Country well-water or spring-water should ordinarily be boiled before using. INSTRUCTIONS FOR THE SUMMER In addition to advising parents as to a selection of a summer resort for the family the physician must advise the mother as to the particular care of the child during the summer, whether he is to remain in town or go to the country. During the months preceding the heated term every mother whose infant is under supervision should be made aware of the dangers of the next few months, and receive written directions as to how to pass through the summer with the greatest security. Selection of Milk.—The mother is told what market milks are the best. She is told that the milk must be kept on ice, with ice surround- ing the bottle, from the time of its delivery until it is given to the child, except, of course, during the time spent in its special preparation. Reduction of Food Strength.—During the hot months in the city the child’s digestive capacity is not equal to that of the colder months. Children who remain in the city are given weaker milk mixtures, in which the fat and protein are reduced from 15 to 25 per cent, by diluting with water, the sugar remaining the same. The infant may not gain very much in weight, but on a reduced diet he is much more capable of passing through the summer without intestinal disorders, and has abundant opportunity to gain later. Clothing.—Mothers are instructed as to the amount of clothing re- 836 THE PRACTICE OF PEDIATRICS quired. They are told that a napkin, a muslin slip, a loose-mesh knitted band, are all that are required on a very hot day. Water to Drink; Bathing.—They are instructed to give the infant frequent drinks of boiled water between feedings, and if he suffers much from the heat, as shown by prickly heat and restlessness, to give him two or three spongings daily with a cool solution of bicarbonate of soda, 1 teaspoonful to a pint of water. Both nursing and bottle babies as a rule do not need much water between feedings. On very hot days, however, when the child perspires a great deal an ounce or two of water may be given occasionally between the usual feedings. Withdrawal of Milk.—It is made very plain that either vomiting or a green, undigested stool is a danger-signal which always means that the milk must be withheld for twenty-four hours or longer whether the child is nursed or bottle fed, and that either barley-water or one of the other carbohydrate gruels (p. 94) must be substituted until such time as the stools improve or the vomiting ceases. This is one of the most impor- tant life-saving measures the physician can teach the mother. An immense majority of the intestinal diseases of summer, which des- troy thousands of lives yearly, have their origin in neglected acute indi- gestion and diarrhea, which if properly managed would mean a slight illness of but a day or two. It is further impressed upon the mothers that upon resuming the milk it must be given at first greatly reduced in strength, and then gradually increased until food of the usual strength is given. Beginning with | ounce of skimmed milk in each feeding, by watching effects upon the temperature and the stools, one may make an increase of perhaps 1 ounce each day. How to Obtain Safe Milk.—Not a little trouble in the past has been experienced in securing safe milk for infants who were removed at a con- siderable distance from the depots of the better class of dairies that supply certified milk. In remote country districts, where the milk is furnished by the farmer, a special arrangement may be made, by which he agrees that the cow’s belly, udders, and teats shall be wiped off with a damp cloth before milking; that the milker’s hands shall be washed before milking; that the few jets of the foremilk shall be thrown away; and that as soon as the milk is drawn it shall be strained through absorbent cotton into a quart milk bottle, suitably corked, and placed in a pail of cracked ice. The cracked ice and the absorbent cotton are, of course, to be furnished by the consumer. For the extra trouble the farmer should receive a special price for the milk. At one resort three babies were sup- plied in this way, by one small producer, with a comparatively safe milk. The improved covered milk pail insures a much cleaner milk, as it offers much less opportunity for droppings to fall into it during the milking than does the old-style pail. For those who have country homes and who can control their milk- supply the above precautions may be carried out to the letter. By such careful control of the home product, and by the use of milk from those dairies only which observe the above precautions, the acute digestive disorders of summer among patients have been rendered very unusual. 837 INSTRUCTIONS FOR THE SUMMER These precautions, with the knowledge of the mother or nurse as to what to do at the first sign of a digestive disorder, will reduce the number of the so-called summer diarrhea cases to a very insignificant figure. Among out-patients in large cities who have to use other milk and milk less clean, summer diarrhea must prevail. Among these, however, the death-rate has been remarkably reduced through the education of the mothers. The mothers are told that a diarrhea is never without dangers; that an infant who has frequent attacks of indigestion during the cooler months is very sure to develop diarrhea during the hot months, and that the safest means of keeping a baby well in the summer is to keep him well all the year round. Rules for the Care of Dispensary Infants and Young Children During the Summer 1. Clothing.—During the very hot days the baby should wear a napkin, a thin gauze shirt, and a thin muslin slip. An abdominal binder made of thin material, and loosely applied, may be worn until the child is six months of age.1 2. Bathing.—Every child should have one tub-bath daily. On very warm days from two to four ten-minute spongings with cool soda water (1 teaspoonful of bicar- bonate of soda to a pint of water) wTill greatly add to the child’s comfort. 3. Fresh air is of vital importance. Leave the windows open. Keep the child in the open air when possible. Avoid the sun. Select the shady side of the street and the shade in the parks. 4. Sleep is very necessary for growing children. A noon-day nap of at least two hours should be insisted upon until the child is four years of age. 5. Soiled napkins should be placed in some covered receptacle containing water, and washed at the earliest opportunity. 6. Drinking-water.—Boil 1 quart of water every morning. Put it into a clean bottle. Keep the bottle in a cool place. Give the water between the feedings—as much as the child will take. 7. Breast Feeding.—The mother should wash the nipple with plain cold water before each nursing. She should be very careful as to her diet and habits of life. Her bowels should move once a day. Constipation in the mother produces illness in tlie child. The mother should have three plain, well-cooked meals daily, consisting largely of milk, meat, vegetables, and cereals. From birth to the third month: The baby should be nursed at three-hour intervals during the day. Seven nursings in twenty-four hours, with only one nursing between 10.30 p. m. and 6 a. m. Third to sixth month: The nursings should be at three-hour intervals during the day; six nursings in twenty-four hours, with no night nursing. Sixth to ninth month: The child now takes a larger quantity at each feeding and should be nursed at four-hour intervals; five nursings in twenty-four hours. Ninth to twelfth month: The nursings should be at four-hour intervals; five nursings in twenty-four hours. 8. Bottle Feeding.—The bottle should be thoroughly cleansed with borax and hot water (1 teaspoonful of borax to a pint of water) and boiled before using. The nipple should be turned inside out, and scrubbed with a brush, using hot borax water. The brush should be used for no other purpose. There should be three or four sets of bottles and nipples. The bottles and nipples should rest in plain boiled water until wanted. Never use grocery milk. Use only bottled milk which is delivered every morning. The milk should be boiled for five minutes immediately after receiving. The feeding hours are the same as in breast feeding. Children of the same age vary greatly as to the strength and amount of food required. Food, when prepared, should be poured into a covered glass fruit-jar and kept on the ice. For the average baby the following mixtures will be found useful: For a child under three months of age: Nine ounces of milk, 27 ounces of boiled water, 4 teaspoonfuls of granulated sugar. Feed from 3 to 4 ounces at three-hour in- tervals—seven feedings in twenty-four hours. Third to sixth month: Eighteen ounces of milk, 30 ounces of barley-water, 6 teaspoon- 1 After this age the binder, although not necessary, is still desirable. Even in trop- ical countries the “belly band” is held in great repute as a prophylactic in forestalling intestinal disorders. 838 THE PRACTICE OF PEDIATRICS fuls of sugar. Feed 5 to 6 ounces at three-hour intervals—six feedings in twenty-four hours. No night feeding. Barley-water is prepared by boiling a tablespoonful of prepared barley flour in 1 pint of water for twenty minutes; strain and add water to make 1 pint. Sixth to ninth month: Twenty-four ounces of milk, 24 ounces of barley-water, 6 teaspoonfids of granulated sugar. Feed 7 to 8 ounces at four-hour intervals—five feed- ings in twenty-four hours. Ninth to twelfth month: Thirty-eight ounces of milk, 12 ounces of barley-water, 6 teaspoonfuls of granulated sugar. Feed 7 to 9 ounces at four-hour intervals—five feedings in twenty-four hours. 9. Condensed Milk.1—When the mother cannot afford to buy bottled milk, when she has no ice-chest or cannot afford to buy ice, she should not attempt cow’s milk feeding. Canned condensed milk should be used as a substitute during the hot months only. The can, when opened, should be kept in the coolest place in the apartment, carefully wrapped in clean white paper. The feeding hours are the same as for fresh cow’s milk. Under three months of age: One-half to 2 teaspoonfuls condensed milk; barley-water No. 1 (see Formulary, p. 94), 2 to 4 ounces. Third to sixth month: Condensed milk, 2 to 3 teaspoonfuls; barley-water, 4 to 6 ounces. Sixth to ninth month: Condensed milk, 3 to 4 teaspoonfuls; barley-water, 6 to 8 ounces. Ninth to twelfth month: Condensed milk, 4 to 5 teaspoonfuls; barley-water, 8 to 9 ounces. 10. Feeding After One Year of Age.—All babies should be weaned at the age of twelve months unless other orders are given by a physician. The bottle fed, also, at this age require more than milk and cereal water. During the second year children are almost invariably badly fed. Four meals a day should be given at the same hours every day. The mother will select suitable meals from the following articles: soft-boiled egg; scraped rare beef; strained broth of beef, mutton or chicken, with stale bread broken into it; toast and butter; stale bread and butter; toast and milk; stale bread and milk; oatmeal (cooked three hours) and milk; hominy (cooked three hours) and milk; cornmeal (cooked two hours) and milk; farina (cooked one hour) and milk. The milk used must be boiled during the hot weather. Physicians are frequently consulted as to the age when, and the con- ditions under which, it is permissible to take the baby out-of-doors. To answer this, the place in which the child lives, the season of the year, and the age and condition of the patient must be taken into consider- ation. A child, regardless of the age, should never be taken out in inclem- ent weather. If under one year he should not go out if the temperature is below 20° F. During the midday heat of summer the baby is better off in the largest and coolest room in the house or on a shady veranda. On very windy days the young infant should not go out; neither should he go out when the snow is melting in large quantities. When going out, on account of unfavorable conditions of the weather is prevented, there should, however, be no lack of fresh air, and this may be insured if the child be given an indoor airing, dressed as for the daily outing. All the windows of the nursery or some other large, sunny room should be opened on one side of the room only. The doors should be closed, so that currents of air are avoided. The child should then be placed in his carriage, suitably covered, and left in the open room all day, except when he is fed and “changed.” Here he receives most that is good from outdoors and avoids much dust and moisture that is objectionable outside. This method will be found very useful in caring for “winter babies” DAYS TO GO OUT-OF-DOORS; INDOOR AIRING 1 Evaporated milk is a suitable substitute. (See p. 79.) THE EXERCISE PEN 839 —those born during the late fall or winter months. The indoor airing may be given for a week or more before the infant is taken out. By this means the child may be gradually accustomed to a change of tem- perature from that of the average living-room to that out-of-doors, and will not be harmed when finally taken out. After an illness, further- more, indoor airing will afford a means of returning earlier to the daily outing. This indoor method of giving a child fresh air will be found useful with very delicate children also, who, by reason of their condition, may be unable to go out during the winter months for several weeks at a time. Few days during the winter are too cold or too stormy for the indoor airing. THE EXERCISE PEN In another chapter, in speaking of “colds,” and how children are exposed to the influences which may bring about what is known as a Fig. 148.—The exercise pen. “cold,” the custom of allowing a child to sit on the floor and play at all seasons of the year has been referred to as a most frequent means of exposure. There is always a current of air near the floor, as one readily discovers by resting his hand on the floor on a cold winter day; further, the floor of the average house is naturally the most unclean part of the dwell- ing. Here dust gathers and dirt from the street collects as it is brought in on the feet of older members of the family. On this necessarily un- clean floor the young child is often permitted to spend a considerable portion of his waking hours. It may readily be seen that countless numbers of bacteria may be transferred through the medium of the hands from the floor to the child’s mouth. Hugs and pillows, which are sometimes used, while cleaner than the floor, are of little assistance in preventing drafts. 840 THE PRACTICE OF PEDIATRICS Exercise is very necessary for the child’s proper growth and develop- ment. He must have an opportunity and place in which to creep, walk, and run. In order that he may have these advantages and not be subjected to unfavorable influences the exercise pen (Fig. 148) has been devised. After being bathed, dressed, and fed the child is placed in the pen on a rug or quilt. Toys are given him and the door is closed. He cannot come in contact with the stove, he cannot roll downstairs, and he is in no danger from the rough play of older children. He is given an opportunity for active exercise without a possible chance of injury. Specifications: The pen can be made of any size, but the usual size is 4 feet square. It can be made of any light-weight wood, pine generally being used. The legs should be at least 12 inches long, bringing the enclosure well off the floor. The pen should be so con- structed that it may readily be taken apart and put together again, iron tenon hooks and iron mortices being used to hold the parts together. The floor may be made of any thin material. One-half inch pine boards nailed together, or papier-mache sup- ported by narrow strips of board, may be used. The floor may be supported by strips of board about % by 2 inches, which are fastened to the inner sides of the end-pieces. Hie pen is best placed in the corner of the nursery or the living-room. Its size may be determined entirely by the size of the room. During warm weather in the country the pen may often be used out-of-doors. COLD SPONGING IN FEVER Sponging with plain water, with salt water (a teaspoonlul of salt to a pint of water), or with alcohol and water (1 part alcohol to 3 parts water) is a means of reducing high temperature, with which every physician should be familiar. Cool sponging at 75° to 80° F., with plain or medi- cated water is useful for two purposes: as a sedative and for the reduction of fever. In measles or scarlet fever, although the temperature may not be high, the itching and burning of the skin prevent sleep, and the patient is very uncomfortable, but often, under such conditions, he will fall asleep during a careful sponging. In pneumonia, in typhoid fever, and in the intestinal disorders of summer, nurses may well have a standing order to give a cool sponging for fifteen minutes at any time when, in their judgment, it may be indicated, not on account of the fever, but because of the sedative effect upon the patient. A sponging of ten to fifteen minutes three or four times a day with cool water (65° to 75° F.) will greatly help a baby, whether sick or well, to pass successfully through the hot period of summer. Sponging for fever, while possessing less antipyretic value than do other measures, such as a cold pack, for example, has the advantage that it is safe and easy of application in the hands of the most unskilled, and is of assistance in influencing high temperature when other means are not available. In order not to antagonize or frighten timid children it is often wise to begin with the water at 95° F., and reduce the tem- perature gradually by the addition of cold water or small pieces of ice. It is rarely necessary to go below 60° F., and usually the sponging should not be continued longer than thirty minutes. It is well to have an interval of rest—from thirty to ninety minutes—between the spongings, as too frequent sponging, if resisted, may exhaust the patient. Every part of the body should be sponged in turn, but it is not necessary to expose the patient, who should be covered with a flannel blanket. When the pro- the cool pack 841 cedure is completed, the skin should be briskly rubbed for a few minutes with a dry, rough towel. THE COOL PACK The cool pack, properly applied, is free from the slightest danger to the patient, and is the best means we possess with which to combat a continued high fever. The pack may be used as freely and with as much success in treating the exanthemata as in dealing with typhoid fever or pneumonia. That cool water may not safely be applied to the skin of a child with scarlet fever or measles is a fallacy which it is our duty to expose to mothers. The pack is prepared as follows, a rubber sheet being used to protect the bed-sheet: A large bath-towel, or some thick, soft, absorbent mate- rial, should be used. Muslin, linen, or any thin material does not answer so well. Slits are cut in the towel large enough for the arms to pass through, and the towel is folded around the body, enveloping only the trunk and buttocks (Fig. 149). The pack should not extend below the middle of the thighs. This leaves the arms and the greater part of the lower ex- tremities free. A hot-water bag, carefully guarded, should be placed at the feet and the patient covered with a blanket of medium weight. The towel is moistened with water at 95° F. This higher temperature is neces- sary at first in order not to frighten the patient, as sudden cold is apt to do, and also to avoid shock. In two or three minutes the towel, without being removed, is again moistneed with water at 90° F., later with water at 85° F., and still later, at 80° F. When the temperature of the water reaches 80° F., it should be maintained at this point for half an hour; then the patient’s temperature should again be taken. If at the begin- ning his temperature was 105° F. and now shows little or no reduction, the temperature of the water with which the towel is moistened should be reduced to 70° F., or, if necessary, even to 60° F. The child, throughout the treatment need not be disturbed, except to be turned from side to side in order that the towel may be wet with water of the desired tem- perature, this being one of the advantages of the pack over a tub-bath or sponging. The towel, or other application employed, should not be used for more than six hours without being replaced by a fresh one. For the first hour or two in a pack the temperature of the patient should be taken every half-hour. When the fever is reduced to 102° F. the pack should be removed, for, if it is continued longer, too great a re- duction may take place. If the fever rises again rapidly to 105° F. or higher it is well to keep the patient in the pack continuously. The degree of cold necessary, in the individual case, to keep the temperature within safe limits will soon be learned. A boy four years old with lobar pneumonia was kept in packs for seventy-two hours. In this case a continuous pack at 70° F. was required to keep the body temperature at 104° F. or slightly lower. Another reason for frequently taking the temperature is that, early in the attack, we do not know how the fever will be affected by the con- tinued cool applications. In some children it is very readily influenced, and in such a case collapse might follow a very sudden reduction of the 842 THE PRACTICE OF PEDIATRICS temperature. In cases readily controlled, the pack may be necessary for only one-half hour or an hour, at intervals of three or four hours. An ice-bag may with advantage be kept at the head when the child is in the pack. Suddenly enveloping the entire skin surface in a cold sheet at 70° F., as advocated by some writers, may increase the temperature and occasion grave symptoms of impending death, because of the sudden contraction Fig. 149.—The cool pack. of the superficial blood-vessels, which sends the blood to the viscera, producing congestion of the internal organs. BATHS The newborn child should be given, daily, a basin-bath with luke- warm, boiled water and Castile soap until the cord falls and the navel heals. When this has taken place, the tub-bath may be given. The temperature of the bath for the very young infant should not be below 95° F. nor above 100° F. Very young infants should not be kept in the water more than three minutes. After the third or fourth month a temperature of 90° to 95° F. is best, the child being kept in the water about five minutes. At this age the tub-bath is best given at night, just before the baby is put to bed. A basin-bath may be given in the morn- ing. When the child is a year old and fairly vigorous, the temperature of the water at the beginning of the bath should be 90° F. This should gradually be reduced to 80° F. by the addition of cold water, the child being vigorously rubbed with the hand while in the water. The tem- perature of the room should be from 76° to 80° F. during the bath, and windows and doors should be closed. When removed from the tub the child should be dried quickly and thoroughly, the folds of the skin being well powdered. A sponge should never be used at any stage of the bathing process and should never be included in the nursery outfit. Sponges are never clean after they have once been used. Some children have a dread of the bath, and cry frantically when placed in the water. This is due to fear, and may usually be overcome by placing a sheet over the tub and lowering the child on the sheet into the water. The Cold Douche.—For “runabouts” from two to three years old it may not be wise to use water below 70° F., but during the entire twelve months many children over three years have a cold douche after the 843 BATHS cleansing bath at the temperature at which the water runs from the faucet. In winter, in New York houses, this ranges from 50° to 60° F. In giving the cool douche the child should stand in warm water covering the ankles. The douche may be used in the form of a spray or shower, or the water may be applied by means of a sponge at the desired tem- perature. The head, if the shower or spray is used, should be suitably protected by an oilskin or rubber bathing cap. After the cold douche there should be a vigorous friction of the skin with a rough towel. If there is not a quick reaction, if the skin does not become warm and glowing, warmer water should be used. So also if there is blueness of the extremities and “goose flesh/’ water less cold should be used, but the douche should not be discontinued. In the great majority of homes the bathing of the child can be carried on with greater convenience immediately before bedtime. He should receive the warm bath and the cool douche, and then, in night-clothes, a warm wrapper, and suitable foot covering, should eat his supper. How- ever, if this time is not convenient, he may be given the evening meal at 5.30 or 6.30, and one hour later have the bath and go to bed. Tub-baths for Fever.—Place the child in water at a temparature of 95° F. and reduce to 80° or 75° F. by the addition of ice or cold water. The duration of the bath should not be more than ten minutes. Constant friction should be maintained during the entire process. Basin Bathing for Fever.—Add 8 ounces of alcohol to a quart of water at a temperature of 70° F. The child is stripped, covered with a flannel blanket, and the entire body sponged with this solution for ten or fifteen minutes. Drying the skin should not be practised. Allow the alcohol and water to evaporate from the body surface, as by this means a greater reduction in the temperature will be effected. Either the tub-bath or the basin-bath may be used by the mother in case of sudden .high fever-—104° to 105° F.—before the physician arrives. She should be so instructed. Bathing for Comfort m Hot Weather.—The basin-bath and tub- bath may also be used as a means of relief during very hot weather. One or two basin-baths a day, with a tub-bath at bedtime during this trying season, will give the child much relief, and help him to pass safely through the heat period. The very young feel the extreme heat most acutely, and endure it with difficulty. Nothing else will give a restless, uncom- fortable, heat-tormented child such a refreshing sleep as a cool tub- or basin-bath. Mustard Bath.—A mustard bath is prepared by adding a heaping tablespoonful of mustard to 6 gallons of warm water. A time allowance of five to ten minutes for the bath is all that is advisable. The special use of the mustard bath is in the treatment of convulsions. This measure will be found useful also for nervous children who sleep badly. Two or three minutes in the mustard water, followed by a quick rubbing immedi- ately before going to bed may prove all that is required to induce refresh- ing sleep. Brine Bath.—A brine bath — 4 even tablespoonfuls of salt to 1 gallon of water at a temperature of 95° F.—is of great service with very delicate, poorly nourished children. Its action is that of a tonic. If the body is 844 THE PRACTICE OF PEDIATRICS thoroughly soaped and washed with plain water and then immersed in the brine bath, no further rubbing is necessary. Ordinarily, the child should be kept in the bath for five or ten minutes, constant friction being continued during the entire time. The brine bath is not applicable to children with intertrigo or eczema. Soda Bath.—The soda bath is of some service in cases of prickly heat, from which many children suffer during the summer. A table- spoonful of bicarbonate of soda should be added to each half gallon of water used. The temperature of the water should be that to which the child is accustomed. From two to four minutes in the water suffices. There should be little or no friction of the skin. It should be dried with soft towels. Bran Bath.—The bran bath also is of service in treating prickly heat. One cup of bran is mixed with the water in the bath-tub and the same method employed as for the soda bath. Starch Bath.—The starch bath is also useful for soothing an irritated skin. One-half cupful of powdered laundry starch is mixed with the water in the bath-tub, and the same method employed as for the soda bath. Hot Bath.—The child is placed from three to five minutes in water which has been raised to* a temperature of 105° to 110° F. Constant friction of the extremities is maintained during the bath. BATHING IN ILLNESS There is a pronounced objection among many to bathing children when ill, particularly when they are suffering from respiratory diseases or from the exanthemata. The functions of the skin as an organ of ex- cretion and elimination are most important, and it is absolutely neces- sary that, during illness, when the metabolic processes of the body are being carried on to an excessive degree, all the eliminating organs be kept in the best possible condition in order that they may the better do their work. There is no better means of stimulating the skin to a sharp reaction than bathing with weak salt water—a teaspoonful of salt to a gallon of water—at a temperature of 85° to 90° F., followed by a brisk rubbing. Every sick child should recive a sponge-bath at least once daily. It is the sudden contact of cold air with the moist skin, which occurs some- times in undressing a child, without the attendant reaction, that causes the shock, the “cold,” which is usually attributed to the bath. It is the temperature of the room in which the child is undressed, the careless method of bathing, and not the application of water, which cause the trouble. Even the danger of this exposure is greatly overestimated. In order to avoid every possible danger, however, the temperature of the room in which the sick or delicate child is bathed should be raised to 80° F. AVe have yet to know of a patient who has suffered from effects of a bath properly given and we know of hundreds who have suffered because of its omission. HEAT THERAPY Heat has long been used as a therapeutic agent. For infants and children it has a wide range of usefulness, both as dry heat and when conveyed by the use of water as a vehicle. HEAT THERAPY 845 Moist Heat.—Heat, conveyed by water, is used as follows: In colic and indigestion and as a diuretic, internally. In acute gastritis, as a sedative, taken by sipping. In conmdsions, idiopathic and uremic, by means of baths. In conmdsions, idiopathic and uremic, in colon flushings at 105° to 110° F. In colic, in the form of a hot stupe applied to the abdomen. In torticollis, as a hot compress to the neck. In sprains, as a hot compress to the joint or muscle. In acute articular rheumatism, as a hot compress to the joint. In retention of the urine, as a hot compress applied to the lower ab- domen and bladder. In suppression of the urine (acute nephritis), in the form of a poultice or hot compress over the kidneys and in colon flushings, 105° to 110° F. In cerebrospinal meningitis, as a hot bath or hot compress to the trunk and lower extremities. In pleurisy, as a hot compress to the painful area. In acute angina, as a gargle. In conjunctivitis, as a hot compress. To hasten suppuration in an abscess, as a poultice or compress. In retropharyngeal abscess and in peritonsillitis (quinsy), as a throat douche. In earache, as a douche or by means of a hot-water bag. In toothache, by means of a hot-water bag, or as hot water held in the mouth. In facial neuralgia, by means of a hot-water bag. In prematurity and in lowered vitality or reduced temperature after disease, by hot-water bags or bottles. Dry heat is used in the following conditions: In prematurity, lowered vitality, or reduced temperature after disease, by means of the electrotherm. In suppression of the urine (acute nephritis), by the electrotherm or by hot air. In myalgia, arthritis, and incomplete restoration of function after fracture, by the electric oven. In various forms of dermatitis and for the healing of gramdating burns, by the electric-light bath. Precautions.—In using heat with children caution should be exercised as to the degree employed. Serious burning accidents have occurred by the use of hot-water bottles and hot compresses. When used very hot the hot-water bottle should be guarded by wrapping it in flannel. Moist heat in the form of compresses, poultices, and stupes should always be tested by placing them against the face of the attendant. The adult hand will often bear a greater degree of heat than is safe to apply to the skin of an infant or young child. In using hot packs, hot-water bags, the electrotherm, or dry heat generated by a lamp or other device, a thermometer should be placed between the child’s clothing and the bed- clothing. A temperature of 110° F. is the highest safe to use with chil- dren. When water is the vehicle, the patient must be most carefully 846 THE PRACTICE OF PEDIATRICS watched and the application frequently renewed because of the rapid evaporation. A compress or poultice must not be allowed to get cool. A piece of flannel or oiled silk or rubber tissue over a hot compress will obviate the necessity for frequent changes. COUNTERIRRITATION The counter-irritants found especially useful in pediatrics are mustard, capsicum, turpentine, camphor, chloroform, and iodin. Counterirritants are useful for two purposes—for the relief of pain and for effect upon internal inflammation and congestion. Without doubt the disease conditions in which counterirritation is of most value are the acute affections of the respiratory tract, such as bronchitis, bron- chopneumonia, and pleurisy. In acute bronchitis, when the terminal bronchi are involved, when there is cyanosis and rapid respiration—■ from 60 to 80 per minute—keeping the thorax enveloped in a mustard plaster, 1 part mustard to 2 of flour, until the skin is well reddened, will often reduce the respirations from 20 to 30 per minute, so that the child, previously tossing and restless, will fall asleep. Repeatedly nurses and mothers have asked if the counterirritation in such cases could not be applied more frequently because of the apparent relief experienced by the patient. The applications may often be made with advantage at intervals of from four to six hours. The counterirritant should be suffi- ciently strong to produce the desired redness of the skin in from five to ten minutes. This will usually be produced by using at first 1 part of mustard to 2 of flour. When the skin becomes tender from the repeated applications, but 1 part of mustard to 5 or 6 of the flour may be required. If the plaster is made too weak, it must remain long in contact with the skin, which thereby becomes macerated. Indications.—In Acute Inflammations of the Respiratory Tract.— When the bronchitis is of the asthmatic type, characterized by decided bronchial spasm associated with bronchial catarrh, the counterirritation furnishes not a little relief. In this condition the whole thorax should be enveloped. In bronchopneumonia with considerable bronchitis local applications of mustard over the involved areas are to be advised. The pain from pleuritic inflammation occurring independently of, or at the onset of, lobar pneumonia, or developing during bronchopneumonia, may be considerably relieved by counterirritation. Here also the mus- tard should be used only over the painful area. When the pain is severe, equal parts of mustard and flour may be used for the first application, if carefully watched, for the reason that a quick, sharp skin reaction should be produced. The mother or nurse should always be cautioned to watch the skin under a counterirritant so that a blister shall not be produced. In no condition is it necessary to blister a child’s skin. We have no evidence that there is any curative action beyond that of a sedative retarding the inflammatory process within. That a respiratory disease is ever aborted by these methods, as claimed by some, is, however, exceedingly doubtful. During the stage of engorgement and congestion of the bronchi, indicated by roughened or sonorous breathing with occasional sibilant COLD AS A THERAPEUTIC AGENT 847 rales, brisk counterirritation with mustard, or with camphorated oil and turpentine, appears frequently to hasten the progress of the case to- ward recovery. If the turpentine is used with the camphorated oil, the proportion should be 1 part of turpentine to 2 parts of the camphorated oil. The mixture should be well shaken before use and applied vigorously with the hand for ten minutes or until a distinct redness of the skin is produced. The mustard or the turpentine should be used in these cases at least three times a day. Rarely in susceptible individuals turpentine applications may cause albuminuria. Capsicum vaselin may be used in the same way and for the same purpose as the camphorated oil and turpentine. In Colic.—In severe colic a turpentine stupe will often furnish prompt relief, 20 drops of turpentine being mixed with 1 pint of water at 106° F. Into this a piece of flannel is dipped, then wrung sufficiently dry not to moisten the bed-clothing, and placed over the abdomen. Over the moist flannel is placed a dry flannel and oiled silk so as to retain the heat and moisture. The application may be renewed, if necessary, every fifteen or twenty minutes. In Pleurisy and Empyema.—When adhesions exist after empyema or pleurisy, while the pain is not acute, there is an uncomfortable drawing, dragging sensation in the chest, which may persist for months. This has been relieved in a few cases by the tincture of iodin, U. S. P., painted over the painful parts every third or fourth night. In intercostal neuralgia, not infrequently found in overworked school- girls, the repeated application, at intervals of three or four days, of tincture of iodin over the point of exit of the involved nerve will often be followed by complete cessation of the pain. Acute Articular Rheumatism.—For the pain in acute articular rheu- matism, chloroform liniment, U. S. P., may be applied to the joint, or, better, the solution of lead and opium, U. S. P., may be applied warm by means of old linen covered with oiled silk. COLD AS A THERAPEUTIC AGENT In the treatment of children cold is generally used in the form of compresses, baths, or packs, and is indicated in the following conditions: In tonsillitis, acute 'pharyngitis, and headache, in the form of a cold compress. In meningitis and pyrexia, by means of the ice-bag or the cool coil. In appendicitis, by means of the ice-bag. In endocarditis and pericarditis, by means of the ice-bag. In fever, by means of baths, cold packs, sponging, and for older chil- dren, by colon flushings. (Not lower than 70° F.) In adenitis and in threatened superficial abscess, by means of an ice- bag. In hysteria and neurotic states, as a spinal douche. In malnutrition of older children, as a tonic, by means of a moderate cool spinal douche following a warm bath. For further details as to the application of cold in special diseases the reader is referred to the discussion of the diseases in question. 848 THE PRACTICE OF PEDIATRICS BLOOD TRANSFUSION AND INTRAMUSCULAR INJECTION Blood transfusion1 has been practised in some form since the dis- covery by Harvey of the circulation; and devices to accomplish the trans- fer of blood were employed by Folli, and des Gabets, a Benedictine monk, as early as the middle of the seventeenth century. Authentic accounts exist recording successful operations in transfusion by Richard Lower and by Jean Denys in the years 1666-1667. In 1667 Denys and King successfully transfused blood from a sheep to a man by means of two cannulas united by a section of carotid artery taken from a horse or ox. As a means of injecting blood the syringe was employed by James Blun- dell in 1818. Later forms of apparatus were all modifications of a direct connecting mechanism of some sort, such as that of Lower, or of a “con- ducting system” supplemented by an “impellor” or syringe. During the past quarter of a century the practice of transfusion which for many years was held in disrepute because of fatalities (many of which were due to antagonistic action between the blood of donor and that of recipient), has been revived with remarkably good results, and the technic has been simplified sufficiently to render the operation relatively free from risk in ordinary hands. The successful but difficult methods of Carrel and Crile have now given place to three methods which are in general use: (1) the Lindemann syringe and cannula method, together with the Unger2 modification which consists in the employment of a stop-cock controlling a syringe which transfers the blood from donor to recipient, at the same time per- mitting the systematic flushing of the connected cannulse with saline solu- tion from a second syringe which forms part of the apparatus; (2) the Klimpton paraffin cylinder method3 in which the total amount of blood to be transfused is collected in a paraffin-lined cylinder and then intro- duced into the vein of the recipient; (3) the citrate method, in which the drawn blood is mixed with a sterile 2.5 per cent, sodium citrate solution to prevent coagulation, and then injected by gravity into the recipient’s vein. The choice of method is a matter of familiarity with and perfection of technic, but it has been maintained that there are more post trans- fusion reactions with the citrate method than with the unmodified blood methods. Most of the bad results ascribed to transfusion in the past have been due either to incompatibility of blood, i. e., “hemolysis or agglutination of the red blood-cells of either donor or patient by the serum of the other,” or to failure to select donors free from infectious disease capable of trans- mission in the blood. Preliminary tests are, therefore, always essential to exclude the possible occurrence of hemolysis and to insure the absence of such types of blood infection as syphilis and malaria. In testing donors for the transfusion of children the simple and rapid method of Rous and Turner4 has proved entirely satisfactory. It con- sists of direct matching of drops from the two bloods, in different pro- 1 Hooker and Satterlee in Johnson’s Operative Therapeusis, vol. i, p. 337. 2 Jour. Amer. Med. Assoc., lxiv, p. 582. 3 Klimpton, Jour. Amer. Med. Assoc., July 12, 1913. 4 Rous, Peyton, and Turner, J. R., Jour. Amer. Med. Assoc., June 12, 1915, vol. lxiv, pp. 1980-1982. INTRAMUSCULAR MEDICATION 849 portions, under the microscope, without incubation in the ordinary sense of the term. The indications for transfusion in children include severe secondary hemorrhages from whatever cause (whether typhoid fever or tonsil- lectomy), severe secondary anemia, the cause of which can be controlled, hemorrhagic disease of the newborn, purpura, and occasional cases of malnutrition or infectious disease. In the actual application of transfusion in a child’s case the external jugular vein or the median basilic is selected to receive the blood and the amount introduced is seldom over 7 ounces. Repeated small transfusions seem to be more effective than a single large transfusion. In secondary anemias 8 to 10 c.c. of blood per pound of body weight has brought about marked improvement. The advantages of direct blood injection over transfusion are con- siderable; the technic, which consists only in extracting the blood from the vein of the donor and injecting it intramuscularly, can be carried out by any physician. Tests for agglutination and hemolysis are not required. The intramuscular injection of whole, freshly drawn blood in hemor- rhage neonatorum has an almost specific curative effect, even in doses of 10 to 20 c.c. The blood is best injected into the glutei and need not be typed for compatibility. Illustrative Cases.—This method has been repeatedly successful in absolutely con- trolling the hemorrhage in the writer’s cases. In each, 1 ounce of blood was injected— ounce into each buttock. Transfusion was used in treating a child who developed a severe purpura after diphtheria. There were extensive hemorrhages under the skin and uncontrollable bleeding from the nose and gums. Six ounces of blood was transfused by Lindemann, using his own method. The bleeding promptly ceased and the child recovered. There is no doubt that the issue would have been fatal had transfusion not been promptly employed. A boy eight years of age developed severe influenza, double otitis media, double mastoiditis, and sinus thrombosis of the right side, for which operations were performed as the occasions arose. Recovery was proceeding slowly, and after three weeks of a most exhausting illness lobar pneumonia developed. It seemed that recovery was now im- possible. The parents were advised that transfusion held out the only hope. Two transfusions were given by Lindemann, using his own method, with an interval of two days. At the first transfusion 8 ounces of blood was given; at the second, 6 ounces. The boy then recovered and was perfectly well two years after the illness. Beyond all doubt, recovery would have been impossible without the transfusions. Transfusion in several cases of extreme secondary anemia in infants was followed by complete cure (p. 440). One case showed no improvement. (For Transfusion in Acidosis see p. 777.) INTRAMUSCULAR MEDICATION Intramuscular injection of drugs and other substances is a common procedure. The sites most commonly used are in the glutei, the triceps, the deltoid, the rectus femoris, and the pectoralis major. The skin over the area is cleansed in the usual manner and the needle is inserted through the skin deeply into the muscle. Beside the usual medicaments thus ad- ministered, special reference should be made to the intramuscular injection of neosalvarsan by the Rosen needle which has a curved phlange at the hilt. This method is discussed under the treatment of syphilis (p. 749). 850 THE PRACTICE OF PEDIATRICS INTRAPERITONEAL INJECTIONS Another route for the injection of fluids in extreme cases of dehydration is the intraperitoneal. By this method normal saline, 2 per cent, glucose, and 2 per cent, sodium bicarbonate solutions may be rapidly and safely injected. The ordinary gravity set is used, the container being placed about 18 inches above the infant’s body. The site of injection (about 2 inches below the level of the umbilicus) is thoroughly cleaned with soap and alcohol and painted with 2 per cent, tincture of iodin. Under strict asepsis the needle (No. 16 or 17 intravenous) is inserted in an upward direction through the abdominal wall into the peritoneal cavity, and the flow started. It is essential that strict asepsis be observed and that the injected solution enter the peritoneal cavity at a temperature equal to that of the body, not less than 100° F. This method has distinct advantages in the facility and rapidity with which it may be employed. Absorption from the peritoneum is rapid and complete. The intravenous method may be employed for the injection of normal saline, sodium bicarbonate solution, glucose solution, sera of various kinds, whole or citrated blood, or drugs. The commonest sites for such injections are: (1) the superior longitudinal sinus, (2) the external jugular vein, and (3) the median basilic or cephalic veins in the cubital fossa. 1. The Superior Longitudinal Sinus. — The Goldbloom1 needle (Fig. 150) has proved most satisfactory for use at this site. It consists of a beveled metal block 3 cm. in thickness, through which a needle 4 cm. long passes, leaving 1 cm. of the needle projecting. The length of the pro- jecting portion of the needle may be varied and fixed by a set-screw. The scalp over the an- terior fontanel is shaved, washed with green soap and alcohol, and painted with iodin. Under rigid asepsis the sterile needle is inserted in the midline at the apex of the posterior angle of the fontanel. The needle is pointed downward and backward at an angle of about 50 degrees until the sinus is entered. The obturator is removed from the needle and blood withdrawn or injec- tion made. Injected solutions should be of body temperature and should be made slowly, with careful watching of the infant’s color, pulse, and respiration. Upon completion, the needle should be quickly withdrawn and moderate pressure exerted on the site of puncture. A collodion dressing is applied. This method is of great value in dealing with small infants whose superficial veins may be difficult to find and to handle. It should not be INTRAVENOUS MEDICATION Fig. 150.—The Goldbloom needle. 1 Amer. Jour. Dis. Child., 1918, vol. xvi, pp. 388-390. HYPODERMOCLYSIS 851 employed when other veins can be readily entered, or without extreme caution in technic. 2. External Jugular Vein.—The skin over the sternomastoid muscle is cleansed and rendered aseptic in the usual manner. With muscular effort or crying the vein will be seen to stand out in the region of the sternomastoid. The needle is then inserted with one stroke through the skin and into the vein, keeping the line of the needle parallel with that of the body. 3. Median Basilic or Cephalic Veins.—The skin over the bend of the elbow is cleansed in the usual fashion, a tourniquet lightly applied above the elbow until the veins stand out, and the needle inserted at one stroke through the skin and into the vein. When necessary the skin over the vein may be infiltrated with 1 per cent, novocain and a small incision 1 to 1.5 cm. in length made exposing the vein in the subcutaneous tissues. Fluids or medication injected intravenously should be given by syringe or by gravity from a container a short distance above the level of the vein. HYPODERMOCLYSIS Hypodermoclysis is one of the means employed to introduce drugs and fluids into the body by other than the gastro-intestinal route. This procedure is used chiefly after hemorrhage, in acidosis, in marasmus, and in active diarrhea in cases in which there has been excessive loss of bodily fluids. In acidosis a 4 per cent, chemically pure bicarbonate of soda solu- tion is employed, alone or with 4 per cent, of dextrose. From 4 to 6 ounces may be used at one time, and the injection repeated in four to six hours. In marasmus and diarrhea a sterile normal salt solution is used. Netter has claimed to have had signally good results in marasmus in the use of sterile sea-water. The amount of solution used varies with the age of the child or the object in view. From 2 to 4 ounces are usually employed. In using the bicarbonate of soda after this fashion there is some danger of producing necrosis of the tissue at the site of the injection. This, ac- cording to Howland, may be obviated by sterilizing the solution by heat. The bicarbonate is then changed to the carbonate, and as the carbonate is very irritating, it must be changed back to the bicarbonate. This can be accomplished by passing carbon dioxid through the cold solution, to which a few drops of phenolphthalein have been added, until it be- comes colorless. That the danger of necrosis in using the chemically pure bicarbonate of soda in sterile water has been somewhat exaggerated would be suggested by the observations of a former associate, Dr. Mercer Blanchard, who used the 4 per cent, solution in treating 50 infants at the New York Nursery and Child’s Hospital with but slight local irritation of very temporary duration. The solution is introduced very slowly by gravity, the container being placed about 2 feet above the child’s body. 852 THE PRACTICE OF PEDIATRICS LAVAGE (STOMACH WASHING) To Seibert is due the credit of first calling attention in this country to the value of stomach washing. Its use was soon appreciated by ped- iatricians generally, and at the present time it is an indispensable therapeu- tic measure. In the vomiting of children, whether due to pylorospasm, acute gastro-enteric infection, chronic indigestion, or a subacute attack of chronic gastritis, it is equally valuable. The dangers of stomach washing may be said to be practically nil. A colleague a few years ago, while washing the stomach of a child two years of age, turned away for a moment, when suddenly the struggling child disconnected the tube from the glass connecting rod and swallowed the tube. Attempts at its removal through the bowel were unsuccessful; gastrotomy was performed, the tube removed, and the child recovered. This is the only accident of any kind we have ever known during stomach washing. The Operation.—For lavage the child is easiest handled when the arms are pinned to the sides by a towel passing around the body. He may rest on his back in a crib, or sit upright on the lap of the nurse or mother. The clean left index-finger of the physician is placed upon the base of the patient’s tongue. The tube, moistened with the fluid to be used in the washing, not with oil, is passed down over the base of the tongue into the esophagus. Passage of the tube into the larynx is practically impossible. We have washed the stomachs of many hundred children, and the introduction of the tube has never been at- tended with difficulty. When it has entered the esophagus, it should be passed rapidly into the stomach. At least 9 inches of the tube will be required to reach the lower portion of the stomach. At first the child will cough, retch, and become red in the face, but this need cause no alarm. He will soon cry and begin to breathe regularly. When the tube is in position the funnel should be held the length of the tube, 2| to 3 feet, above the patient’s body; the water, which should first be boiled, may then be poured into the funnel. At first the water may remain stationary in the funnel, owing to the pressure of air in the stomach and the straining of the child. When the child relaxes or the air escapes, being forced upward through the water, the water will pass rapidly into the stomach. The apparatus described under Gavage (p. 853) is used. It should always be boiled before using. If much mucus is present, a 1 per cent, solution of boric acid or borax may be used. The amount intro- duced into the stomach at one time varies with the age of the child. For a baby of one week 1 ounce may be used; at six weeks, 2 ounces; at six months, from 4 to 6 ounces. It is rarely advisable to introduce more than 6 ounces at one time. The fluid is allowed to run into the stomach and is then siphoned out by lowering the funnel, the process being repeated until the fluid returns perfectly clear. From 1 to 2 pints of water may be necessary to complete the washing. Indications.—It is rarely necessary to wash the stomach oftener than twice in twenty-four hours. Ordinarily, in the acute vomiting cases, one washing daily for four or five days will answer. In cases of chronic indigestion with regurgitation the washing will be needed less frequently—once a day or once every second or third day. GAVAGE 853 The following is frequently the history of a case of chronic indiges- tion with vomiting: There has been for several weeks vomiting of food and mucus two or three times daily. The stomach has been washed, the child carefully dieted with a plain barley-water or a weak milk mix- ture, and no vomiting has occurred for perhaps twelve to forty-eight hours, when the regurgitation or vomiting again commences as before. In such a case it will soon be learned how frequently the washings should be repeated in order to control the vomiting. Illustrative Case.—A child six months old suffering from malnutrition had a history of persistent vomiting after each feeding. A greater part of the food taken was lost. What was not vomited was digested imperfectly, as was shown by the stools. The stomach was washed and a large quantity of thick mucus and curds removed. The child was given a barley-water diet. There was no vomiting for three feedings, and then only a small quantity of barley-water was ejected. After three days, following daily washings, the vomiting entirely subsided. The child was given a weak milk mixture, one-fifth milk and four-fifths barley-water, and no significant vomiting resulted. The food was carefully strengthened, and although in two weeks the vomiting had en- tirely ceased, the washings were continued at intervals of two or three days for a month until the water siphoned out was free from mucus. In severe cases of chronic indigestion the washings at intervals of two or three days may be continued with advantage for several months. It must be remembered that in these chronic cases of indigestion the patient is ill through abuse of the stomach—usually because too strong food has been given, or too much of a suitable food has been given at too frequent intervals. As important, then, as the stomach washing is the giving of food suited to the child’s digestive capacity. The field of usefulness of lavage is not entirely confined to vomiting cases. Children with indifferent appetite and limited food capacity, but without vomiting, are often greatly benefited by the treatment. A not infrequent story is that food is taken without relish and that coax- ing is necessary in order that the child shall eat. The loss of appetite is usually the result of improper food or faulty feeding methods. Some patients are absolutely indifferent to food; many refuse it altogether. In cases of this class a stomach washing once a day will often be followed by a surprising improvement in the appetite. There is no better appetizer for many of these pitiful looking babies. In not a few instances we have been surprised at the large amount of mucus removed from the stomach of one of these children who had shown no vomiting whatever. The fact teaches us that there may be, in infants, stomach disorders of considerable importance without vomiting or, in fact, without any other symptom than loss of appetite and malnutrition. GAVAGE Gavage, or forced feeding, is the introduction of nourishment into the stomach by means of a tube. The tubes are to be obtained at the instrument makers and are known as “stomach-tubes for children,” or the physician can make one himself at a small cost. All that is re- quired is a soft-rubber catheter, American No. 12, a |-inch glass tube 2 inches long, 2 feet of {-inch plain rubber tubing, and a small glass funnel. An extra opening should be cut in the catheter about \ inch from the 854 THE PRACTICE OF PEDIATRICS outlet. This allows a more rapid introduction of the nourishment. The opening can very easily be made with a small pair of curved scissors. The position of the child for gavage may be the same as for stomach washing, or the child may rest on his back. It is well to clear out the stomach with warm water before each feeding. In giving gavage to children without teeth the bare index-finger is all that is necessary to keep the mouth open. In handling children with teeth a dependable gag should be used. Indications.—Gavage will be found useful in three types of cases: In Obstinate Vomiting.—Several years ago, when the senior writer was resident physician at the New York Infant Asylum, a series of observa- tions were made on cases of persistent vomiting which could not be con- trolled by stomach washing or ordinary methods of treatment. It was found that patients who could not retain a teaspoonful of water administered by a spoon or a bottle would retain from | to 1 ounce of water given through a tube. The same child who vomited 1 teaspoon- ful of milk or other food would retain this amount and a great deal more when the food was given by the tube. This discovery led to more ex- tended observations. Twenty cases of persistent vomiting in all were treated in this way, of which 18 were relieved. (This series of observa- tions was the first made relating to the use of gavage or forced feeding in persistent vomiting.1) For the obstinate vomiting cases it is well to use gavage only once every four or six hours, with from one-third to one-half the quantity of food given in health. The tube which is to be passed into the stomach should never be oiled, but merely dipped into the solution that is to be used. It is then passed in rapidly with the funnel empty, and the nourishment is immediately poured into the funnel. When the food has passed into the stomach, the tube should be compressed and quickly withdrawn, as some of the liquid will be retained in the tube if it is withdrawn slowly. If this is done without compressing the tube, an escape of food into the larynx may take place during the withdrawal of the tube and cause choking, cough- ing, and perhaps vomiting. The food selected should consist of thin dextrinized gruels, or broths and gruels combined, which have proved of great value in some cases. In severe illness, such as diphtheria, pneumonia, and the grave intes- tinal diseases, gavage may save the life of the patient. Not infrequently in such cases insufficient nourishment is taken to support life. Rectal feeding is usually of value only for a day or two, as children soon become intolerant. In such circumstances gavage may be employed advantage- ously for several days at a time. In fact it is, in such an instance, the only way by which the child can be properly nourished. Predigested cereal foods, completely peptonized milk, and stimu- lants well diluted may be given. Usually these patients badly need water. If there is no tendency to vomiting, a large quantity of water may be given with the nourishment selected, so that they may receive as much liquid as in health. 1 Kerley, Gavage in Persistent Vomiting in Infants, Archives of Pediatrics, Feb- ruary, 1891. COLON irrigation; colon flushing 855 In Malnutrition, Exhaustion, and Narcosis.—Gavage is also most useful in cases of extreme malnutrition and exhaustion, or in alcoholic or opium narcosis. Infants suffering from an extreme degree of malnutri- tion and exhaustion are often so reduced in strength that not enough energy remains for the taking of nourishment. In these cases gavage is distinctly a life-saving measure. To a child four months of age from 4 to 6 ounces of a suitable mixture may be given every two hours. Before the next feeding it is well to introduce a few ounces of water and withdraw it to see if the food has been properly digested. By this means of feeding there will be noticed, if the vitality is not at too low an ebb at the commencement, a daily increase in strength and vigor, which proves that the powers of assimilation persist after the desire for food or the child’s ability to swallow it has been lost. This proves that we must never regard such a case as hopeless so long as the child is breathing. Time and again, after a few days’ feeding in this way, the child will take the food from the bottle or spoon. Breast milk, if it can be obtained, may be given by gavage as successfully as can predigested cow’s milk. The malted foods on the market have also been used tem- porarily with advantage, for, while deficient in nutritive value for the well, they afford sufficient nourishment for temporary use by the very ill, and are easy of digestion. Illustrative Case.—A patient three months old was almost moribund as the result of extreme malnutrition. The temperature ranged from 94° to 96° F. for several days. No food could be taken. A wet-nurse was secured, but the child would not nurse. He was pale, apathetic, and too weak to cry. The wet-nurse’s milk was drawn from the breast and spoon feeding attempted, but swallowing was impossible; If ounces of breast milk were fed by gavage, but this proved too strong, and the child promptly vomited. The milk was then diluted one-haff with weak barley water. At first 1 ounce was given at a feeding; then this was gradually increased to 2 ounces, all the feedings being retained and digested. In a week the child was able to nurse, and made a com- plete recovery, weighing, when seven months of age, 14 pounds. At the time gavage was commenced the weight was but 5 pounds. COLON IRRIGATION; COLON FLUSHING Colon irrigation was brought prominently into use several years ago as a remedy in the summer intestinal disorders of young children. While unquestionably its usefulness in this respect has been overestimated and the irrigation overdone, in selected cases it is of great service. Be- cause a child has summer diarrhea, colitis, or any disorder of the intes- tine, it does not follow that irrigation is indicated or that he will be bene- fited thereby. A child who is having a passage from the bowels every half-hour or hour is not a fit subject for irrigation. The colon is kept empty by the active peristalsis, and the washing will remove nothing more than a few shreds of mucus. The cases benefited by irrigation are those in which peristalsis is not particularly active. When a child is running a temperature of 102° F. and over, with five or six green mucous passages daily, one or two colon irrigations a day will unquestionably be of service in removing the offending material from the intestine. Every year we see cases of intestinal infection, particularly those of a very acute type, in which there are high fever, intense prostration, and infrequent bowel action. Occasionally we see a case of this sort in which there is no movement whatever without assistance. In such cases 856 THE PRACTICE OF PEDIATRICS colon irrigation is of inestimable value, and may be used with advantage as often as once in six or eight hours. The washing, even if properly con- ducted, is apt to be strongly objected to by the patient and should be completed as soon as possible. Too frequent irrigation, with strong med- icated solutions, may keep up the mucous discharge indefinitely. In a few cases the resistance with straining is so marked and so continuous that irrigation is impossible. These cases are usually those of children who, on account of the excessive peristalsis, do not require irrigation. In conducting the irrigation normal salt solution at 95° F. is ordinarily used, and a quart usually suffices. If there is a great deal of mucus and blood, a 1 per cent, tannic acid solution is better. The irrigation should be continued until the solution returns clear. The temperature of the solution may be varied with advantage, depending upon the nature of the case; thus, in cases with subnormal temperature and intense pros- tration, cases of the so-called “algid” type, the solution at 110° F. will act as a decided stimulant. It raises the body temperature and improves the pulse and the general condition of the patient. In cases with high fever—105° to 106° F.—a cold solution answers better. A temperature as low as 70° F. has been repeatedly employed, and it has often been found that an irrigation with 4 pints of water at 70° F. will reduce the body temperature 3 degrees. For irrigation a soft-rubber catheter, No. 18 American, is best, for the reason that its walls are stiff and the tube does not easily bend upon itself in the manner of an ordinary catheter. Should this occur, the water may escape an inch or two within the rectum, and obviously be of no service. When the tube, well lubricated, has been introduced for 9 inches, the tip will have passed into the descending colon, and further introduction will be of no advantage. When the end of the tube is in the colon gentle palpation over the left side of the abdomen will enable one readily to locate the tip. The tube is attached to an ordinary fountain- syringe by passing the distal end over the smallest rectal tip, which is a part of the outfit of every fountain-syringe. The bag should be held not over 3 feet above the child’s body. When the water is allowed to run, the buttocks should be pressed together to encourage retention sufficient to insure flushing of the entire large intestine. If this can be done, the irrigation will be most efficient. In this connection should be mentioned a particularly beneficial effect of irrigation, the absorption of a portion of the salt solution by the intes- tines. Not a few of the intestinal cases show a very limited food capacity. As a result of the vomiting and very frequent liquid stools the body is thoroughly drained of fluids. In such cases, after the washing is completed, we endeavor to have the child retain as much as possible of the normal salt solution. As an aid to this the child should be placed on his left side with the buttocks elevated and the tube introduced well up into the de- scending colon. The buttocks should be pressed together so as to assist in retaining the water after it has passed into the bowel. When a half pint or a pint has passed in, the tube should quickly be withdrawn and the child kept for half an hour in a recumbent position with the buttocks elevated. The salt solution will be best retained when it is used warm, at a temperature of from 100° to 105° F. VACCINATION 857 Colon flushing consists in passing into the descending colon a con- siderable quantity of fluid, such as normal salt solution or bicarbonate of soda solution, ounce to 1 pint. The measure is used with much benefit in selected cases in which but little fluid is taken by the natural channel. The possibilities of the large intestine for absorbing fluids when they are urgently needed by the organism are surprising. Illustrative Cases.—A boy with cyclic vomiting who had retained absolutely nothing given by mouth for three days retained 1 pint at the first colon flushing, \ pint more after six hours, and another -j pint six hours later. The flushings were begun on the third day of the attack. Although the prostration was extreme, the prompt improve- ment in the general condition of this patient was most gratifying. After the first injection the pulse improved, the apathy disappeared, and the child began to ask ques- tions and showed interest in his surroundings. A boy nine years of age, ill with scarlet fever, who could take very little fluid, was able to retain 8 ounces of a salt solution given at eight-hour intervals for three days. A child six months of age had retained absolutely nothing in the stomach for six days because of an intussusception. On the sixth day the respiration was superficial and slow. He was cold and practically pulseless. The second heart sound could be heard but faintly with the stethoscope. The intussusception very unexpectedly was reduced by water pressure (p. 280). Hot salt-water flushings were at once begun; the patient retained 12 ounces, given at a temperature of 110° F., and in a few minutes exhibited very perceptible improvement. With repeated flushings at six-hour inter- vals the child continued to improve and made a perfect recovery. Severe toxic cases of diphtheria and scarlet fever, in which but little fluid is taken and in which the toxicity of the blood is extreme, as shown by the stupor and delirium, are often much improved by the free use of colon flushing, which supplies the water which the child needs, but which cannot be given by mouth, or, if given, may not be retained. Method.—We usually order the salt solution given in quantities of from | to 1 pint, depending upon the age of the child, at intervals of from six to eight hours, never at a lower temperature than 100° F. The apparatus required is a small rectal tube attached to a fountain- syringe. The flushing is best given with the patient resting on the left side, with the buttocks elevated on a pillow, the tube, well oiled, being intro- duced at least 9 inches into the bowel. The solution at 105° to 110° F. is allowed to pass into the bowel, and the tube is then quickly withdrawn. To facilitate the retention of the fluid the patient should remain on his side for one-half hour. VACCINATION Every infant in fair health should be vaccinated. The vaccination should be done as soon as the child is thriving on a rational diet. The younger the child at the time of vaccination, the less the constitutional disturbance. In well infants vaccination should never be delayed beyond the fifth month. The site selected for the vaccination in boys is usually on the left arm, at about the point of insertion of the deltoid, and in girls on the outer aspect of the calf of the leg. It has been found, however, that it is a matter of much more convenience to the mother in dressing and handling the child if the leg is selected in both sexes. The dressing is 858 THE PRACTICE OF PEDIATRICS more easily applied to the wound and can more readily be kept in place on the leg. Further, in the manipulation necessary in dressing and un- dressing, much less discomfort is occasioned when the sore is on the leg. The Method.—Before scarification of the skin the site selected should be well scrubbed with common soap and water, dried, and then washed with alcohol. The area of scarification should not be over \ inch in diameter, and should be sufficient to produce only a light flow of serum. A deep scarification, producing a free flow of blood, is very apt to be un- successful. The best scarifier is an ordinary sewing needle, which should be sterilized by placing the point for a few seconds in an alcohol flame. The virus which is furnished in hermetically sealed capillary glass tubes is the safest to use. The drop of virus is to be deposited on the abraded surface and rubbed well into the wound, using the side of the needle for this purpose. When the wound is thoroughly dried, a protective dressing should be applied. The safest and most convenient is a sterile gauze bandage, which is wrapped several times around the arm or leg and secured with a safety-pin. On account of the shape and position of the parts the bandage is very apt to become displaced downward. In order to prevent this a strip of adhesive plaster 1 inch wide and 5 or 6 inches long may be placed over the bandage at right angles to it; the middle portion of the plaster readily adheres to the bandage, and the two ends, at least 2 inches long, are anchored to the skin. The After-treatment.—The mother should be instructed to report seven days after the vaccination. On the seventh day the dressing may be removed, and if the vaccination is successful, the characteristic pearl- like vesicle will be present. If, on account of accident or rubbing of the parts by the patient, the vesicle is broken, the non-adhering gauze should be carefully cut away around the sore, allowing that which adheres to remain. Under no conditions should the wound be opened. Again, a gauze dressing should be applied and kept in position by adhesive strips. At the end of the exudative stage, usually about five or six days, the dressing should again be changed, either by the mother or the phys- ician, and renewed until the crust falls, the third to the fourth week after the vaccination. If there is no sign of the vesicle in ten or twelve days, the vaccina- tion, if primary, should be repeated. Revaccination should be prac- tised at least once in five years and at more frequent intervals during epidemics of smallpox. Constitutional Disturbance.—A certain degree of constitutional disturbance is present in every case in which the vaccination is success- ful. After the first month, however, the younger the child, the less the constitutional disturbance. Children vaccinated during the second or third month suffer practically no inconvenience. There is a rise in temperature—from 100° to 101° F.—for a day or two, and when the process is at its height, perhaps a slight degree of restlessness. Repeatedly it is observed that children, vaccinated at this age, pass through the various stages without manifesting the slightest discomfort. In older children the severity of the constitutional symptoms appears to increase with the age. Thus, a child in the second or third year may have fever, 102° to 104° F., loss of appetite, coated tongue, and moderate prostra- VACCINE THERAPY 859 tion. Very active symptoms rarely last longer than three days unless there is considerable accompanying cellulitis. Complications.—If vaccination is properly performed the dangers attending it are practically nil. That death and serious results have followed vaccination is no argument against its use, but a grave reflec- tion on the manner in which, as a rule, it is performed. The scarifica- tion of bacteria-laden skin, producing at the outset an open wound which is indifferently or not at all protected from further infection, is very apt to produce complications of a troublesome and often serious nature. Erysipelas, extensive cellulitis, and sloughing of the parts as the result of careless vaccination are not infrequently seen. In 2 cases we have seen reinoculation as the result of scratching the sore, the virus being transferred in one case to the upper lip and in the other to the upper eyelid. Vaccination Shield.—There is not a vaccination shield on the market, with which we are familiar, that is safe for use. Some cause a maceration of the wound, others allow a free entrance of bacteria, while still others prevent a free superficial circulation of the blood and increase the chance of ulceration. Moreover, the shields are very apt to become displaced, causing a rupture of the vesicle, with resulting infection. Local Applications.—Active treatment, except for relief of the im- mediate constitutional symptoms, is rarely required. Even when there is an active cellulitis we have found it advisable not to attempt local applications, such as lotions or compresses. All ointments have a ten- dency to dissolve and loosen the crust, producing an open wound. When, on account of suppuration, the crust falls, leaving a deep ulcer formed by granulation tissue, active local treatment will be required. Such ulcers are often seen in out-patient work. A wet dressing of a saturated solution of boric acid has answered well in these cases. If the wet dress- ing cannot be kept properly applied, a 10 per cent, ointment of boric acid, applied twice a day, will be found of considerable service in hasten- ing the closure of the wound. The ointment should be smeared freely on gauze or clean linen and held in position by a properly applied ban- dage. In young children the ulcers are often most obstinate. In a few instances we have known them to continue from eight to ten weeks. In cases in which the healing has been particularly slow, the familiar dressing of balsam of Peru (5 per cent.) in castor oil, applied twice daily on a pad of several thicknesses of gauze and covered with oiled silk, has appeared to hasten the granulation. Unhealthy granulations may have to be cureted or treated with silver nitrate before the dressing is applied. VACCINE THERAPY Fundamental Principles.—Vaccine therapy for prevention or cure of infection has for its object the production of an active immunity to the specific bacteria concerned, while serum therapy produces a passive immunity only. Immunity, which is resistance or lack of susceptibility to a given disease or micro-organism, may be natural or acquired. Artificial or acquired immunity may be the result of an attack of the disease itself 860 THE PRACTICE OF PEDIATRICS or may follow inoculation with living cultures of micro-organisms in sublethal doses or in an attenuated state, with dead cultures, or with those products of the growth and metabolism of bacteria known as toxins. Immunity so acquired is active or direct, comparatively slow in ap- pearance, and of comparatively long, though variable, duration. It is brought about by the development in the blood-serum of substances antagonistic to the vital activity of the bacteria or to the toxins. Such substances are known as antibodies. The serum of an animal which has been actively immunized and which is rich in antibodies may be inoculated into another animal for the purpose of combating infection. The immunity thus produced in the second animal is indirect or passive and of comparatively short duration. The antibodies are of several kinds: agglutinins, opsonins, bacteri- cidins, and lysins. They are formed by the tissue cells under the stimu- lus of the infecting bacteria, at first locally, then generally, and are pres- ent in the serum and to a lesser extent in the other body fluids. They manifest themselves in certain definite ways, demonstrable and measur- able by laboratory methods: agglutination reaction, opsonic index, bac- tericidal tests, and the complement deviation test. Clinically, their increase is accompanied by amelioration of the symptoms of infection. The aim of both vaccine and serum therapy, then, is to aid the production of antibodies in order to effect a destruction of the invading bacteria and the neutralization of their toxins. Metchnikoff claimed that the destruc- tion of micro-organisms is brought about by their ingestion by phagocytes, especially polymorphonuclear leukocytes. Denys and Leclef proved that there is a substance in the blood-serum which prepares the bacteria for phagocytosis. This sensitizing substance was named “opsonin” by Wright and Douglas, who elaborated methods for its study in the lab- oratory and for its practical application to the treatment of infections by means of vaccines made of suspensions of dead bacteria. It has been found in general that the opsonins are below normal at the onset of an infection and during the height of the acute stage, and that, as improvement occurs, the amount of opsonin in the blood-serum increases. The administration of dead cultures of the bacteria causing the infection stimulates the production of opsonins. Determination of Opsonic Index.—In order to estimate the opsonic index it is necessary to prepare serum from the patient, serum from a normal person, leukocytes from a normal person, and a culture of the bacteria from the patient’s lesion. Serum is readily obtained by pricking the finger and catching the blood in a small curved glass tube, as recommended by Wright. The blood is allowed to clot in the tube, and the resulting clear serum is re- moved by means of a capillary pipet, which is then sealed at its narrow end. Leukocytes are obtained from a small quantity (about 10 drops) of normal blood caught in a tube containing 10 c.c. of 1.5 per cent, sodium citrate in normal salt solution. The mixture is centrifuged and the fluid carefully drawn off and replaced by normal salt solution, in order to wash the blood-cells free from serum. After centrifuging again the super- natant fluid is removed, and the upper layer of white blood-cells taken 861 VACCINE THERAPY up into a capillary pipet, the lower end of which is then sealed in the flame. This is known as the “leukocytic cream.” The suspension of bacteria is made in normal salt solution from an agar-culture not over twenty-four hours old. It should not be too thick, and should be free from clumps, which may be recovered by shaking or by manipulating with a capillary pipet. Capillary pipets of the same caliber having been selected, equal quan- tities of the patient’s serum, leukocytes, and bacteria are drawn up and thoroughly mixed in one, while normal serum, leukocytes, and bacteria are drawn into another. A control, using normal salt solution instead of serum, should also be made. The pipets are sealed below and incu- bated for fifteen minutes at 37° C. The mixture is then expelled on a glass slide, thoroughly mixed again, and spread on clean slides. After fixing in methyl-alcohol and staining in methylene-blue (Manson stain is excellent for the purpose), the slides are placed under the microscope and the number of bacteria contained within 50 leukocytes is counted. This gives the phagocytic index. The quotient of the patient’s and the normal phagocytic indices equals the opsonic index of the patient. More satisfactory results have been obtained by making the tests with diluted serum, according to Neufeld. The opsonins in the normal blood-serum used for control are found to disappear in a lower dilution than do the immune opsonins in the blood of the patient who has been immunized by the disease or by the administration of vaccines. Detections from 1 :10,000 may be made. As a matter of fact, the test for the opsonic index has been found to be too uncertain to make it practical and worth while to follow system- atically, the clinical symptoms being sufficient indication of the value of the vaccines. Preparation of Vaccine.—A vaccine is made by suspending agar- cultures less than twenty-four hours old in normal salt solution. In order to estimate the dose even approximately the bacterial suspen- sion is standardized by counting the bacteria in relation to red blood- cells. The method is as follows: Equal quantities of bacterial suspen- sion and of blood from a normal person are drawn into a capillary pipet, mixed, and thinly spread on a slide. The red cells and the bacteria are then counted in a number of fields. Since the normal blood contains 5,000,000 red cells to the cubic millimeter, the number of bacteria in pro- portion to the red cells can be estimated per cubic millimeter, and the actual count per cubic centimeter readily calculated. The tube contain- ing the bacterial suspension is sealed and heated for one hour at 58° C. Control cultures are then made to test the sterility of the undiluted sus- pension. This having been properly accomplished, the vaccine is diluted in bottles or ampules with sterile normal salt solution, according to the dose desired per cubic centimeter, and properly sealed. Thus, if the actual count showed that 5,000,000,000 bacteria were present in a cubic centi- meter, diluting the vaccine fifty times by adding 1 c.c. of undiluted vaccine to 49 c.c. of sterile salt solution would make a vaccine containing 100,000,- 000 bacteria in 1 c.c. Injections of 1 c.c. or less are made into the shoulder, back, or thigh under strictest aseptic precautions. Staphylococcus.—In staphylococcus infections vaccine treatment 862 THE PRACTICE OF PEDIATRICS has given good results. While it is always wise to use a vaccine prepared from the patient’s own strain of staphylococcus, it is not absolutely essential that this be done. Any stock vaccine which has given good results in a similar case may be used, provided that it has been proved by a culture made from the pus of the patient’s lesion that staphylococci are the infecting agents. It is essential also to know whether the Staphy- lococcus aureus or albus be present in order that the appropriate vaccine may be employed. The dose in infants under two years should vary from 50,000,000 to 100,000,000 of dead cocci. The inoculations are repeated on the second to the seventh day if necessary. Too rapid or too large dosage must be avoided, because there is danger of exhausting the re- sponding power of the human organism by overstimulation. The tem- perature should be taken before the vaccine is injected, and every three hours during the following twenty-four. Furunculosis in young infants has proved readily amenable to treat- ment by staphylococcus vaccines. Improvement is shown by a much more rapid healing than usual of the furuncles already incised, and by the non-appearance of new ones. After the second inoculation improve- ment is the rule. The amount of pus is lessened and fewer dressings are required than in cases otherwise treated. No bad effects from the injections have been noted. In treating otitis media of staphylococcus origin vaccines are reported, evidently by enthusiasts, as having proved of value, also in treating sup- puration in the antrum, styes, and osteomyelitis. After operation the vaccine has been thought of real service in aiding the more rapid disappearance of pus from the pleural cavity and in hastening the healing of the wound. Obstinate cases of asthma unbenefited by protein therapy have also been reported as favorably affected by staphylococcus vaccine. Any local suppuration due to staphylococci is occasionally benefited by vaccine administration. In general septicemia the results have been encouraging (Wright). Fifty million dead bacilli are to be given at the first injection; this is followed in five days by 100,000,000 and again in five days by 100,000,000. The subsequent administration is depen- dent upon the requirements of the case. Streptococcus.—-In all cases of streptococcus inflammations the results of vaccine therapy have been far less brilliant than in staphylococcus cases, but still encouraging enough to warrant their further use. It seems to be essential, also, far more than in the staphylococcus cases, that the vaccine be prepared from the strain of streptococcus infecting the patient. The dose is about 2,000,000 to 3,500,000 in babies under one year of age, 5,000,000 to 7,000,000 between one and two years, 10,000,000 to 30,000,- 000 in older children. In acute infections streptococcus vaccines are generally contraindi- cated because the antibody production of the body is already stimulated to the maximum and the addition of bacterial toxin may result in harm. Erysipelas.—According to our observation the results of vaccine therapy in this disease have been insignificant. Scarlet Fever.—In scarlet fever the opsonic index to streptococci has been studied by Tunnicliff, who found that it is below the normal at the onset of the disease, but rises when the acute symptoms subside. VACCINE THERAPY 863 As local streptococcus complications appear the index falls once more. Favorable results following the injections of dead streptococci in cases of scarlet fever have not been reported. On the other hand, this treatment of streptococcus inflammations— like subacute or chronic joint affections—has given encouraging results. Typhoid Bacillus.—Inoculations of dead typhoid bacilli as a pro- phylactic measure against typhoid fever have been extensively em- ployed in armies. Relatively early Russell was able to show that the incidence of disease was 6 to 15 times as high among the non-inoculated as among the inoculated soldiers. Not only are the numbers of cases far less numerous among those who have been vaccinated, but the clinical course is much less severe and much shorter, while complications are fewer. In view of these results prophylactic inoculation of children as well as of adults is to be recommended during epidemics of typhoid fever or before entering a typhoid district. Immunization is accomplished in three vaccinations, the dose of which, in children, may be 100,000,000 to 500,000,000 dead bacilli. By lowering the incidence of typhoid fever cases antityphoid vac- cination prevents the development of carriers of typhoid bacilli, and thus is fully justified. Gonococcus.—In vulvovaginitis due to the gonococcus in infants under one year of age, the injections of dead gonococci have had no effect in shortening the course of the disease, in lessening the amount of dis- charge, nor in causing the cocci to disappear from the vagina. In older children Hamilton and Cooke found that the effect of the dead gono- coccus injections is more marked in chronic than in acute cases, the disease being very decidedly shortened in its course. The later stages of the acute cases were also shortened, while no result was noted in the first weeks of the attack. Hamilton and Cooke observed no advantage from the use of a vaccine made from the patient’s own organism. The initial dose of 5,000,000 was gradually increased to 40,000,000 or 50,000,000, according to the needs of the case. Injections at eight- or nine-day inter- vals proved best. (For personal observations see p. 520.) Meningococcus.—In cerebrospinal meningitis due to the meningo- coccus of Weichselbaum vaccine therapy has been tried, but it has be- come superfluous in view of the brilliant results obtained by means of the antimeningococcus serum of Flexner and Jobling. Bacillus Coli Communis.—Inoculations of dead colon bacilli in doses of 10,000,000 to 50,000,000 are reported to have given excellent results in cases of cystitis and pyelitis- due to that micro-organism. The symp- toms are said to subside rapidly, and the bacilli to disappear from the urine in a comparatively short time. In a considerable trial of this method we have had no definite success. Tubercle Bacillus.—Local tuberculous lesions have been treated by injections of tuberculin in very small doses, with good effect. This is true of chronic local tuberculosis without constitutional symptoms, especially in bone, joint, gland, skin, and eye affections. In pulmonary phthisis of a chronic type, running a nearly apyretic course, tuberculin is also of value. In all acute tuberculous lesions with marked fever and general symptoms tuberculin therapy has proved useless, and may be 864 THE PRACTICE OF PEDIATRICS attended by grave danger. The dose of crude tuberculin,1 administered for purposes of immunization in a chronic tuberculous lesion, should be very small, 1/5000 milligram, gradually increased to 1/2000, 1/1000, or more. The inoculations should be repeated not oftener than once in ten days, at first, and the temperature carefully measured every two hours. If a rise occurs, the dose has been too large, and must be reduced at the next injection. In selected cases of bone and joint disease and also in adenitis good results have followed six or eight months of con- tinued treatment, the dose being gradually increased in amount and the intervals shortened to three days. Bacillus Pertussis.—The evidence as to the value of injections of vaccine prepared from the Bordet-Gengou bacillus of whooping-cough is still con- flicting. This subject has been discussed on p. 679. Pneumococcus.—There is considerable evidence to warrant the use of injections of pneumococcus vaccine for increasing resistance prophyl- actically against pneumonia. For curative action the serum or antibody solution is to be selected. (See p. 367.) Cold Vaccines.—“Shot-gun” vaccines prepared from mixed strains of various organisms, including Streptococcus hemolyticus, Streptococcus viridans, staphylococci, Microccus catarrhalis, Bacillus influenzae, and the different types of pneumococcus are gaining popularity in the preventive treatment for colds. At present, however, there is little to warrant the employment of this measure. We have given such treatment in a few instances upon request, and have had favorable reports from the patients, but have obtained no evidence of the actual effectiveness of cold vaccines and cannot recommend their promiscuous use. SERUM THERAPY In most forms of serum therapy an attempt is made to confer passive immunity by the introduction into the body of an infected individual of serum from the blood of another who has a natural or acquired immunity to the existing infection. Serum therapy is of particular value in the treatment of diphtheria, meningococcus meningitis, tetanus, and pneumonia caused by Pneumo- coccus Type I. In scarlet fever, poliomyelitis, and measles good results have been obtained either in efforts at prevention or cure, by the use of the serum of convalescent individuals with recently acquired immunity. The details of application of the method are considered in the respective chapters dealing with the diseases in which it is employed. NON-SPECIFIC PROTEIN THERAPY This form of treatment, under other names, has been employed in one form or another for many years, but only recently has received the consideration which is its due. An ancient example of its efficacy prob- ably exists in the traditional cure of obstinate rheumatism by bee stings. The non-specific reaction may be induced by numerous substances the action of each of which, when injected into the body, is to alter its resist- ance against inflammation or toxemia. In many instances this response 1 Koch’s old tuberculin, as prepared by the New York City Board of Health. NON-SPECIFIC PROTEIN THERAPY 865 is at first made manifest by untoward symptoms such as increased tem- perature (with perhaps chill), a sudden change in the leukocyte count, and increasing malaise, the reaction being anaphylactic. In a second phase, however, leukocytosis, antibody release, and increased resistance on the part of the organism are brought into play and an abortive cure may be attained. The non-specific reaction accounts for much of the benefit ascribed to the use of various non-specific vaccines and to the cures attributed to autoserum injections, horse-serum injections, and injections of whole blood. Treatment of this form undoubtedly has a limited field of usefulness, but is variable in its results and at times may do much harm. The ulti- mate range of applicability of this method is problematic. XXV* DRUGS AND DRUG DOSAGE UNPALATABLE AND NAUSEATING DRUGS It is impossible to mention in detail all the drugs which might be included under this heading. Only those will be referred to which we are obliged to use almost daily in our work—drugs which are either unpleasant to the taste or which may be badly borne by the stomach, or drugs com- bining both these disadvantages. How to administer certain drugs so that their use may be continued and yet not interfere with the digestive function is a question which deeply concerns those who may have children for their patients. The element of taste is most important to a child; therefore, when possible, drugs disagreeable to the taste should be given to children in tablet or pill form or in capsule. The continued use of a drug often depends upon its being made palatable. As a general rule, when pills, tablets, or capsules are given, one-half glass of water should be taken at the same time in order to diminish any possible irritant effects upon the mucous membrane of the stomach. Salicylate of soda is a drug disagreeable in taste and very liable to destroy the appetite and interfere with digestion. In acute rheumatism its use is invaluable, and we are obliged frequently to give it in large doses. It is best given after meals with one-half glass of milk. Fairly large doses at this time, well diluted, are better than more frequent smaller doses. This drug usually is better borne if given in solution with peppermint-water or with simple elixir diluted 50 per cent, with water; but the taste when thus given is only partially disguised, and being still very objectionable to many, may be prevented by the use of a capsule if the patient is old enough, care being taken to give a considerable amount of water or milk with each capsule. Iodid of Potash.—This drug is indispensable and for it no other can be substituted. It is best given in solution. It is most disagreeable in taste and directly irritant to the mucous membrane of the stomach. Like salicylate of soda, it should be given after meals with one-half to one glass of water or milk. It is best given plain, as the saturated solution, which may be dropped into the milk. Bichlorid of mercury is usually given in such small doses that its irri- tant properties are but little felt. It is best prescribed in tablet form, dissolved in two teaspoonfuls of water and followed by a swallow of water. When possible, it should be given after feeding. Alcohol is another drug which should be given well diluted, regard- less of the form in which it is administered. It is best given with or after food, but should always be given diluted with at least 6 parts of water, if whisky or brandy is used. Ipecac and Tartar Emetic, when employed as expectorants, are best given with sugar of milk in powder or tablet form. They should never be given on an empty stomach. Two or three teaspoonfuls of water should precede their administration when they are not given within a 866 ALCOHOL 867 reasonable time after feeding. In many children, when given without this precaution even in the usual doses, these drugs often decrease the appetite and the digestive capacity. The Ammonium Salts.—Carbonate of ammonia must always be given in solution and should always be well diluted with water. Muriate of ammonia may be used in tablet or powder form. Water or milk should precede the administration of either. One part of simple elixir with 2 parts of water makes an agreeable combination. Oils used for nutritive purposes should invariably be given after meals. Plain cod-liver oil or any of the preparations containing it should never be given on an empty stomach. Castor oil is best given when the stomach is empty. A much more prompt and satisfactory cathartic effect is thus produced. The oil may be given in soda-water or coffee, with orange juice, or in pepper- mint-water. Older children sometimes take oil better plain, sandwiched between the two halves of a peppermint cream, first the candy, then the oil, followed by the remainder of the candy. If castor oil is vom- ited, it may be repeated in a few minutes, and often will then be retained. Creosote is most difficult of administration to many children. It is customary to prescribe the carbonate, which is ordered to be dropped into 1 or 2 teaspoonfuls of wine after meals. Creosote may also be given in soft capsules or in an emulsion. Quinin should be given in solution or in capsule. Quinin pills as they are sometimes made, with an insoluble coating, pass unchanged through the entire intestinal canal. For purposes of solution a most satisfactory menstruum is a preparation of yerba santa, known to the trade as Yerbazin (Lilly). Coca-quinin (Lilly) is another palatable preparation. Of the salts the bisulphate should always be prescribed for children, for the reason that it may be given in complete solution without the addition of acid. Strychnin, on account of its taste, is often strenuously objected to, and is therefore better given in tablet triturate form. If the tablet cannot be swallowed, it may be broken into small pieces (not pow- dered) and mixed with a teaspoonful of orange pulp or in a thick cereal jelly. Digitalis, in the form of the tincture or the infusion, should never be given when the stomach is empty, but should be administered after meals or the drinking of water or milk. There are few drugs that will so completely destroy a child’s desire for food as the digitalis preparations when put into an empty stomach. Tincture of Muriate of Iron.—This should be given after meals, well diluted, in at least one-half glass of water. The child should take the medicine through a glass tube so as not to injure the teeth. Iron prep- arations generally should be given after meals, and in case the liquid preparations are used, they should be well diluted with water. ALCOHOL In its relation to children, alcohol, regardless of the form in which it is used, must always be considered as a drug and not as a beverage. It 868 THE PRACTICE OF PEDIATRICS is occasionally of great service in diseases of children and under certain conditions may answer better than any other means of stimulation we possess. The fact that it is grossly misused does not in any way detract from its value in illness. It is too often given; chiefly for the reason that its use, in the form of whisky and brandy and wine, is advocated in medical works in many of the ordinary ailments of childhood where really it is absolutely contraindicated. Its use, in our hands, has been that of a food and stimulant in very grave conditions, the duration of its usefulness being often completed in a day or two. When given to children for a prolonged period, even in moderate quantities, it invariably interferes with digestion and assimilation, and therefore does harm. It is very liable also to act as an additional irritant to the kidneys, which are prone to show inflammatory changes as a result of the systemic toxemia due to the disease. We have heart stimulants which are ordinarily as effective as alcohol and without its danger either to the stomach or the kidneys. It is good practice never to give alcohol early in an illness unless the onset is accompanied by profound prostration, but rather to hold this drug in reserve until it is absolutely necessary. Used in this way, it has been of much service in two conditions in which nothing has been found that can replace it. We refer, first, to that time which may arise in any grave disease when the heart fails to respond to the usual stimulation, as in the crisis of lobar pneumonia and in the profound toxemia of scarlet fever or diphtheria. At such a time the powers of assimilation for most drugs as well as for food are reduced to a minimum. When food is rejected or taken badly, when the usefulness of strychnin, strophanthus, musk, camphor, digitalis, and caffein has been exhausted, alcohol should be given and given in as large doses as may be required to produce the desired results. It is astonishing what large quantities of alcohol may be given in many such conditions without the slighest intoxicating effects. When given well diluted it is usually well borne and assimilated; it supports the heart, improves the respiration, and often will carry the patient through to a successful convalescence even when the outlook is very unpromising. As the system readily becomes accustomed to alcohol, it must be given in increasing doses. If it is given early in the illness, it will have lost its stimulating effects by the time it is most needed. Brandy and whisky, well diluted, are the forms in which it is generally used. The second condition in which alcohol is useful is in cases with greatly lowered vitality resulting from some severe illness, such as typhoid fever, enterocolitis, or pneumonia. If a child is suffering from shock bordering on collapse, or collapse with a subnormal temperature with all the vital powers at a low ebb, alcohol will do much to sustain him until he is able to assimilate easily digested or predigested foods. In such cases whisky, well diluted—1 part whisky to 6 parts of water—given at intervals of two or three hours, will hasten recovery. If the child cannot swallow, the whisky may be given by gavage; if it is vomited, a double quantity, well diluted, may be given by the rectum. The hypodermic use of alcohol is infrequently resorted to chiefly for the reason that other remedies, such as strychnin and digitalis, are more effective than alcohol when so given. The doses vary from 5 drops to \ dram every one or two hours, twelve to twenty-four doses in twenty-four hours, for a child one year of age. A ANESTHETICS 869 child two years of age may be given 1 dram at intervals of one or two hours. The use of alcohol is attended with the least disturbance when it is given after the feedings. ANESTHETICS That the administration of anesthetics to children is attended with considerable danger is proved by statistics relating to the subject, and that the greatest care and judgment should be exercised in the selection of an anesthetic for a child is readily understood. Ether and Chloroform.—As a routine anesthetic for the young, ether is preferable because of its safety. The popular belief that chlorofrom is without danger is in error and not sustained by statistics. There are conditions, however, .when ether is contraindicated. In cases in which there is bronchial involvement, ether increases the bronchial secretions and produces a free flow of saliva, which is liable to be aspirated into the lungs. In case of any obstruction to respiration, from laryngeal diphtheria, retropharyngeal abscess, or enlarged glands which may encroach upon the air-passages, chloroform, and not ether, should be employed. Ether is further contraindicated in scarlet fever or in nephritis. In such cases chloroform is to be selected. Chloroform is to be used also for the sake of convenience, if other conditions allow, in minor operations about the mouth and the nose. Chlorofrom is contraindicated in general weakness, exhaustion, collapse, and in anemia. Ether given by the drop method should be used in these cases. Statistics of chloroform anesthesia show a consider- able mortality in operations for adenoids and enlarged tonsils. The interference with respiration and the sudden hemorrhage make chloroform dangerous in these operations. In heart disease with imperfect compen- sation any anesthetic is dangerous, but ether, by the drop method is the least dangerous. Nitrous oxid gas, which of late has become very popular, should be given with caution to children under two years of age. Young children are very easily asphyxiated by gas; the younger the child, the greater the danger. Gas should be used, therefore, very sparingly and the patient watched most carefully for signs of cyanosis. The use of gas for children frequently precedes the administration of ether, as this practice renders the latter much less disagreeable to the patient. Such procedure is con- traindicated, however, in any condition where dyspnea is present; in fact, in any illness in which respiration is impeded, gas is dangerous. The combination of gas and ether in such cases is not as safe as chloroform, which is to be given in a minimum amount with oxygen as a safeguard. Nitrous Oxid Gas with Oxygen.—The admixture of oxygen renders pos- sible prolonged administration of nitrous oxid without (he risk attendant upon its use alone. This form of anesthesia has become very popular in recent years because of freedom from unpleasant after-effects. The method, however, calls for special apparatus of some complexity and im- poses upon the anesthetist close watchfulness of the variations in degree of unconsciousness of the patient. To secure adequate general relaxation ether as a supplement must often be employed. The method is not with- out the dangers attendant upon ordinary gas administration, but in expert hands may be employed with safety and obvious advantage. 870 THE PRACTICE OF PEDIATRICS Danger-signals with Ether: Marked cyanosis; stertorous breathing; rapid pulse; dilated pupils; short, quick, gasping respiration. Danger-signals with Chloroform: Pallor; ashen color; feeble, shallow respirations, gasping in character; dilated pupils and separation of the eyelids; slow feeble heart action. Danger-signals during Gas Administration: Cyanosis; jerking respirations; dilated pupils; convulsive movements of any portion of the body. Ethyl Chlorid.—The use of ethyl chlorid is in the experimental stage. Statistics show quite a mortality from its use. It should not be contin- uously administered after unconsciousness has set in. In case any of the danger-signals are observed the ethyl chlorid should temporarily or per- manently be discontinued and some other form of anesthetic substituted. DRUGS FOR INTERNAL USE Drug.
