Diagnosis of Equivocal Hypothyroidism, Using Thyrotropic Hormone (Tsh)*†

Thyroid Function in Patients With Sex Chromosomal Anomalies*

“…is e.xpressed as the percentage point increase. The minimal increase generally regarded as being consistent with normal thyroid function is 10 (Schneeberg, Perloff and Levy, 1954;Bishopric, Garrett and Nicholson, 1955). Therefore, in this study, subjects exhibiting an increase of 10 percentage points or less have been considered abnormal.…”

Value of the TSH‐PBI‐test in Diagnosis of Hypothyroidism

“…Previous investigators (2, 3, 4,6, 15) as well as observations made in the present study show that the response of PBI to TSH is a valuable adjunct in the diagnosis of hypothyroidism which can be used even in patients taking thyroid preparations. As to the best technical procedure for routine use several investigators (1,2,5,9,10,11,15,16) feel that determination of thyroid uptake of before and after a single injection of TSH is sufficient. But such a simple technique assesses only the capacity of the thyroid gland to concentrate iodide.…”

The Pituitary and Adrenals

“…In euthyroid patients thyrotrophin caused a decreased urinary excretion of pal (296) and a rise in 1131 uptake (297) ; in primary myxedema these changes did not occur. In contrast, in pituitary hypothyroidism the trophic hormone caused responses similar to those obtained in euthyroidism (296,297).…”
