[Daily profiles of melatonin, cortisol and gonadotropins in 8 adolescents with anorexia nervosa].

From a biological study of 8 patients with anorexia nervosa and an analysis of the daily profiles of gonadotropins, cortisol and melatonin, the authors discuss the possible relationship between anorexia nervosa and affective disorders. At the initial phase of the illness, plasmatic levels of FSH, LH and oestradiol were very low. 24-hour plasma cortisol values were comparable with those of a depressive population; when weight loss was equal to or higher than 25% of the initial weight, there was no suppression by dexamethasone. The daily profile of melatonin was maintained, with melatonin plasma levels significatively higher than in a control group of depressed patients.

[Melatonin. Chronobiologic peripheral endocrine index in depressive states].

The chronobiological studies with melatonin constitute valid arguments to consider melatonin as a peripheral index of depressive disorders. In a group of patients with major depression, we reported a lowering of melatonin nocturnal plasma levels, associated with cortisol hypersecretion. A similar lowering of melatonin was observed in a group of patients with cluster headaches, but without quantitative modification of cortisol secretion. Other studies are necessary in order to determine wether melatonin may be considered as a "state marker" of depression itself or a marker of the genetic vulnerability to depression.

[Use of local cobalt therapy in peripheral neuropathies associated with chronic lymphopathies (lymphoses). 2 cases with histo-immunologic and ultrastructural records].

In two cases of peripheral neuropathy, associated with a chronic lymphopathy, cobalt therapy to the lower limbs provided considerable relief of pain, with partial motor recovery. The disappearance after cobalt therapy of the lymphoid infiltrate of the peripheral nerve leads to discussion of the pathogeni role of this infiltrate. Immunofluorescent and electron microscopic studies form the basis of a discussion of the mechanism of involvement of the peripheral nerve non-secreting lymphopathies (chronic lymphoid leukaemia) and in secreting lymphopathies (Waldenström's disease).
