Reprinted from the Albany Medical Annals, January, 1894. The Treatment of Myxoedema by Feeding with the Thyroid Gland.* By Henry Hun, M. D., Professor of Diseases of the Nervous System in the Albany Medical College. There are, doubtless, many things in medicine of more importance, but few of greater interest, than is the subject of myoxoedema. Although the disease is not common, yet, neither is it of extreme rarity, and whenever seen, it presents on the first glance such striking diagnostic features that it is strange it was not noted as a distinct form of disease before 1874, when Sir Wm. Gull described it in a paper entitled: “ On a Cretinoid State Supervening in Adult Life in Women.” In 1877, Dr. Ord (whose name since that time has been most intimately associated with myxcedema) published a report of many other eases of this disease, to which he for the first time gave the name of myxoedema, believing that the essence of the disease lay in a mucin yielding oedema, and stated the most important fact, that at the autopsy of persons dead from this disease the thyroid gland was either atrophied or its structure replaced by fibrous tissue. In 1882 and 1883 Reverdin and Kocher each published papers showing that a condition identical with myxoedema was produced in con- sequence of the total extirpation of the thyroid gland. Thus, ten years after the disease was first described it was referred to its final cause—the loss of the thyroid gland—a gland whose function up to that time had been merely a subject for hypothesis. *Read before the Albany County Medical Society on December 13th, 1893. 2 During the next few years the proof that myxoedema was due to the loss of the function of the thyroid gland became more and more positive and in 1889 and 1890 many attempts were made to graft a lobe of the sheep’s thyroid in the peri- toneal cavity and in the sub-mammary region of persons suffering from this disease with gratifying but imperfect success. Finally in 1891 and 1892 patients with myxoedema were given the thyroid gland by mouth, at first in the form of a glycerine extract, next in the form of the gland itself slightly cooked and at last in the form of the dried powdered gland. Cases treated by either of these methods improved rapidly and were soon cured, although it was found necessary to continue to give the gland from time to time or relapses would occur. Two cases of myxoedema treated by feeding with the dried thyroid gland I wish to report briefly to-night. It is not necessary to go into minute detail, for the success of this treatment is already well established. The first of these cases is one of four which formed the basis of a paper on myxoe- dema which I published in 1888. His case was reported under the name of Mr. Y. and he is the only one of the four now living. He always drank and smoked to excess and continues to do so now. He contracted syphilis in 1877 and was thoroughly treated for it, partly at home and partly at the Hot Springs of Arkansas. In 1883 the myxoedematous symptoms first made their appearance and steadily progressed in intensity until he presented a typical picture of the disease. He never perspired. The skin was dry and scaly, the epidermis peeling off in great quantities, and presented a slight yellow tinge, which was especially marked on the face and on the scalp. The complexion was waxy and on friction spots of congestion appeared on the cheeks and persisted a long time. The whole top of the head appeared bald, but on close inspection was found to be covered with short brittle stumps of hairs. The nails were riged and brittle and on the latter account troubled him greatly. The face was everywhere swollen and pitted very slightly only on long continued pres- 3 sure. The under eyelids were baggy and wrinkled. The lips were especially swollen, much everted and of a bluish color. The tongue and the tissues of the larynx were swollen and the voice was rough and hoarse. He was very susceptible to the cold and was accustomed to go to the south-west with the advent of cold weather. He was physically weak, his mind was sluggish and he slept much of the time. The disease reached its height toward the end of 1884 and remained stationary throughout 1885. There was then a slight improvement until 1887, since which time his condition remained without material change until July 24, 1893, when he presented himself for treatment, he never before that time having been under my professional care. He was given three times daily a capsule containing five grains of the dried thyroid gland prepared by Parke, Davis & Com- pany and he continued to take ten or fifteen grains daily with occasional intermissions during four months. At the present time he takes the thyroid at the rate of fifteen grains a day during one week in each month. The effect of the treatment has been very decided and has resulted in a complete cessation of all his unpleasant symptoms. The skin is no longer scaly and he perspires freely when he is warm. He is no longer sensitive to cold and he is not covered by half the bed clothes that he formerly required. He even takes a cold plunge bath in the morning and can dress in a cold bath room. He formerly slept twelve and fourteen hours out of the twenty-four, but now sleeps only seven or eight. His speech is quicker, he writes more easily and he walks more. He feels quite well • and his appearance no longer suggests myxoedema. The second case is that of a woman, Mrs. McM., 48 years old, who was sent to St. Peter’s Hospital from Fonda, for relief from a supposed abdominal tumor. She was admitted into the service of Dr. Hennessey, who could discover no abdominal tumor further than the pendulous abdomen so com- mon in case of myxoedema, and who recognizing the case as one of myxoedema, transferred her to me for treatment. 4 Her history is briefly as follows: She has had no children and no miscarriages. Her menstruation has always been regular in time, but somewhat excessive in quantity. Three years ago she suffered from two “ floodings” and since that time has not menstruated. Several years ago her hair began to fall out and has continued to do so; at the same time her teeth and gums became sore, some teeth fell out and others became loose, and at about the same time her legs became swollen and have remained so ever since. She “catches cold ” upon slight exposure and is much more unpleasantly affected by cold than was the case formerly. She is physically weak, can walk only a short distance and even then suffers from dyspnoea. Her mind seems sluggish and stupid. Her complexion is sallow with a spot of congestion on each cheek. Her under eyelids are wrinkled, baggy and translucent, her lips are swollen and everted, a number of her teeth have fallen out and the top of her head is bald. Her legs are swollen and pit but very slightly on long continued pressure. The skin of the arms and legs is scaly, the abdomen is large and pendulous; there is no hair in the axilla or on the pubes, and no thyroid gland can be felt. All the patient’s actions are performed slowly, her speech is slow and her voice hoarse. The patient was given three times daily a capsule contain- ing five grains of the dried thyroid gland, prepared by Parke. Davis & Company, and continued to take them during three weeks, at the end of which time she had improved in all respects. She was more active, perspired more freely, her skin was less scaly and her appearance had changed so much chat the diagnosis of myxoedema could hardly have been made. She was so much better that she left the hospital and I have not seen her since. In the progress towards recovery which these patients made under the influence of the thyroid treatment, two interesting symptoms appeared which occurred also in almost all the reported cases that were treated in this way. The first of these symptoms is a decided loss of weight. The man lost twenty-three pounds in two months, but later when his health 5 was restored he began to gain again and eventually regained eleven pounds, leaving a permanent loss of twelve pounds. The woman lost nine pounds in the first two weeks of treat- ment and was not subsequently weighed. It would seem, therefore, that the thyroid gland taken internally possesses the power of reducing weight. Such has been found to be the case. Putnam* tried it in two cases of ordinary obesity, one of which lost forty and the other forty- eight pounds, and similar results have been obtained by others. I have tried it in a few cases of obesity with satis- factory results. I will mention only one case in which it was put to a rather hard test and yet acted well. Those of us who have had any experience in attempting to reduce obesity, whether by diet or otherwise, are aware that during the first few days or first week or two there is a decided loss of weight, but that after the initial loss a further reduc- tion in weight either does not occur or occurs very slowly. The one case of obesity treated by the thyroid gland, which I wish to report is that of a lady, who, without the slightest change in her diet, had been taking phytolene and had lost seven pounds in weight, but then remained stationary in spite of large doses of the drug. The phytolene was then stopped and she was given five grains of dried thyroid gland three times daily, with the result that she lost a little over three pounds in two weeks, which is quite a loss considering that the patient made absolutely no change in her usual diet. The thyroid gland, therefore, taken internally, appears to have the power of reducing weight in other cases than those of myxoedema. It must always be remembered, however, that several sudden deaths from syncope under the thyroid treatment have been reported and that in cases of fatty and degenerated heart the remedy should either not be used at all or should be given cautiously in very small doses. The second interesting symptom, which occurs in cases of myxoedema while under the thyroid treatment, is a great restlessness and nervous excitement, which is very different ♦Transactions of the Associations of American Physicians, vol. viii, 1893, P- 34°- 6 from the sluggish placid manner customary in myxoedema, and is usually so intense as to necessitate temporary cessation of the treatment. This conditisn of nervous excitement is very similar to that which is a prominent symptom in exophthalmic goitre, and it would seem that myxoedema and exophthalmic goitre are two diseases presenting symptoms the one the direct reverse of the other, and that in myxoedema the symptoms are due to a loss of the function of the thyroid gland, while in exopthalmic goitre directly opposite symptoms are produced by an excess of function of the thyroid gland. If this is true then the essence of exopthalmic goitre and the cause of the symptoms is in the goitre and the quickest and most radical form of treatment would be to extirpate a portion of the enlarged gland. This is a dangerous operation, but it has now been performed a number of times in cases of exopthalmic goitre with gratifying success. Putnam* closes an able article on “Thyroidectomy in Graves’ Diseases” with the following words: “ In all, the summary includes fifty-one cases. There were four deaths attributable to the operation, but in almost all the rest greater or less improvement, and often, substantial cure seems to have taken place. Of course these results are not to be placed entirely to the credit of the operation, since prolonged rest is almost always beneficial, and the influence of time is often of itself useful and even curative.” It would seem, therefore, that in casse of exophthalmic goitre where prolonged rest, electricity and large doses of quinine and iron have failed to give relief, thyroidectomy may result in a complete cure or in decided relief of distressing symptoms. These two symptoms: The rapid loss of weight and the condition of nervous excitement, which occur so uniformly un- der the thyroid treatment, are of great importance, not only in establishing a relationship between myxoedema and other diseases, and in showing the immense influence which the thyroid gland exercises on the nutrition of the body, but also *Journal of Nervous and Mental Diseases, December, 1803. 7 in indicating possible new therapeutic uses for the gland, the value of which must be proved or disproved by future clinical experience. Whether or not any other pathological conditions besides myxoedema will be found to yield to the internal administration of the powdered thyroid gland, there can be no doubt that this disease can be almost invariably cured by it. We have, then, in myxoedema a disease which remained during centuries unrecognized and yet as soon as it was described, it was seen to possess such striking characteristics, that a diagnosis could be made with almost absolute certainty at the first glance. In less than ten years after it was first described, it was definitely referred to its cause(the loss of the thyroid gland), and ten years later it could be cured with almost absolute certainty (by eating the thyroid gland). Such a rapid referring a disease to its cause, and thereby finding its certain cure, is unfortunately an occurrence of great rarity in medicine, and justifies the statement made in the opening sentence of this paper, “That few things in medicine are of greater interest than is the subject of myxoedema.”
