[Plasma cortisol response to intravenous beta 1-24 corticotropin as related to the fat mass and its topographic localisation (author's transl)].

Plasma cortisol response induced by 2.5 microgram/kg beta 1-24 corticotropin (1 hour infusion) in obese females was not related to fat mass. The response was increasingly pronounced as fat predominated in the upper body segment, i.e. android obesity. This phenomenon may be interpreted as indicating an increased adrenal capacity to secrete cortisol in such obese patients. Low level but longstanding excess cortisol secretion is probably the cause of the android features of obesity.

[Whited Addison's disease. Eight cases (author's transl)].

In 8 cases of Addison's disease due to adrenal tuberculosis, the substitutive treatment appeared unnecessary since more than one year. Urinary 17-OHCS were in the normal range but did not rise after ACTH injection except in two cases. In all the cases, plasma ACTH was elevated but lower than in severe adrenal insufficiency, and in the range of those observed in congenital adrenal hyperplasia. The nycthemeral variation of plasma ACTH were maintained. Therefore, an apparently normal basal cortico-adrenal function was obtained by an excessive stimulation by endogenous ACTH. The one year prescription of anti-tuberculosis chimiotherapy to 6 of these patients was possibly responsible for the partial reversal of adrenal insufficiency. However the substutive therapy appears needless in every day life, such a treatment would eventually be necessary during stress conditions.

[Adipose tissue cellularity and skinfold thickness of the deltoid and retrotrochanteric areas in obese women (author's transl)].

301 women, 261 of them obese, were the subject of an anthropometric study of brachial and femoral adipomuscular ratio, adipocytometry in the deltoid and retro-trochanteric areas and oral glucose tolerance. Deltoid adipocyte volume was highly correlated (p less than 0,001) with total fat deposition in this area, while no such relationship was found in the retrotrochanteric area. In obese women with chemical or overt diabetes, deltoid adipose cells were significantly larger than those of non-diabetic obese women. This, however, was not the case for retro-trochanteric adipose cells.

[The present state of hormonal investigation in amenorrhoea (author's transl)].

The value or plasma radio-immune assays of steroid and pituitary hormones in amenorrhoea is discussed. The accent is placed on the need for repeated plasma sampling. Dynamic tests aimed at investigating the hypothalamo-hypophysial-ovarian axes are analysed. A proposal is put forward for a scheme of investigation that will make better use of these tests.
