- n. It has been found that this affection is usually entirely amenable to treatment by extracts and other preparations made from the thyroid gland (throat-sweetbread) of the sheep. The same treatment is often of great value in cretinism, which is regarded as a congenital form of myxedema. The use of preparations of the thyroid gland to supply a deficiency of the secretion of this gland, which is the underlying defect in myxedema and cretinism, affords one of the most brilliant examples of successful organotherapy.

Sorry, no etymologies found.
It assumes variety of forms, the major among them being hypothyroidism also known as myxedema and hyperthyroidism also known as throtoxicosis goitre.
Then, too, a defect in the glands causes the disease known as myxedema in adults and cretinism in children.
After description of the myxedema condition, transplantation and injection of extracts of thyroid tissue was tried.
The patients are usually clinically euthyroid, but signs of hypothyroidism and the myxedema syndrome though rare may occur.
The removal of the thyroid might result in severe myxedema, but the patient at least remains alive.
In myxedema, a condition characterized by a lack of thyroid secretion, there is dulness of the reflexes and of the intellect, a lowered muscular power, and generally a sluggish discharge of energy.
-- In myxedema one of the cardinal symptoms is a persistently subnormal temperature and, though prone to infection, subjects of myxedema show but feeble febrile response and readily succumb.
For example, alterations in the efficiency of the cerebral link may yield neurasthenia, mania, dementia; of the thyroid link, Graves 'disease, myxedema; of the adrenal link, Addison's disease, cardiovascular disease.
Thyroid deficiency in children gives rise to a form of idiocy, bodily malformation and degeneracy known as cretinism, while in adult life it is associated with a similar disorder known as myxedema.
He holds that the observations in myxedema, in obesity, and psoriasis warrant the belief that the thyroid gland eliminates a material having a regulating influence upon the constitution of the panniculus adiposus and upon the nutrition of the skin in general.
