THE SYMPATHETIC SYSTEM 97 



emotions. Those in which hyperthyroidism predominates 

 can be given very small doses of thyroid or 0.005 milli- 

 grams. Those in which the signs of hypothyroidism seem 

 to predominate can be given larger doses: 0.05 to 0.10 

 milligrams. In those in which neither of the two pre- 

 dominate, intermediary doses are given: 0.025 milligrams. 

 According to L. Levi, the reactions to this medication 

 regulate the doses of thyroid. It is easy to see how organo 

 therapy, by using excessive doses, can overreach its 

 objective and cause, in certain patients, the symptoms of 

 hyperthyroidism. The symptoms of hyperthyroidism 

 symmetrically opposed to hypothyroidism are schematized 

 below to allow us to study the thyroid equilibrium 

 in patients. 



HYPOTHYROIDISM HYPERTHYROIDISM 



Dull Expression. Exophthalmos, brilliant eyes. 



Thyroid not appreciable in size. Hypertrophied thyroid. 



Fall of hair. Eyebrow sign. Hypertrichosis, often cf the eye- 



brows.

of sweat. 



Sleepiness, apathy. Insomnia, nervosity, irritability, 



etc. 



Anorexia, constipation. Tendency to diarrhea. 



ACUTE THYROIDITIS, TUBERCULOSIS AND 

 SYPHILIS OF THE THYROID. 



INFLAMMATION OF THE HEALTHY THYROID ,is called 

 thyroiditis; that of an altered gland, strumitis. The 

 latter is the most frequent of the two. 



Thyroiditis is observed most frequently in women be- 

 tween 20 and 40.
