[The anterior pituitary endocrine function in Parkinson's disease]. / La fonction endocrine anté-hypophysaire dans la maladie de Parkinson.

Dopamine exerts an inhibitory or stimulant action on some of the hormones produced by the anterior pituitary gland. The dopamine content of the hypothalamus is considerably reduced in patients with Parkinson's disease. We have tested the anterior pituitary endocrine function in such patients to evaluate the repercussions on this function of the dopaminergic deficiency: the secretion of pituitary stimulins was found to be unaltered both at baseline level and after pharmacological stimulation.

[Influence of metabolic control on peripheral diabetic neuropathy (author's transl)]. / Neuropathie diabétique périphérique. Evolution en fonction de l'équilibre du diabète.

The influence of metabolic control on peripheral neuropathy was studied in a population of adult insulin-dependent diabetic patients. Motor conduction velocity (MCV), measured on the common peroneal nerve, was used as electrophysiological index of neuropathy. Following control of hyperglycaemia, rapid and significant improvement in MCV was observed in diabetics without renal or ocular complications, but not in diabetics presenting with these complications. This would suggest that peripheral diabetic neuropathy is governed by two different mechanisms and that one of these is metabolic, as it can be reversed by reinstating glucide balance.

[Experimental study of neural and neuro-muscular conduction during simulated diving in dogs and rabbits: anatomo-pathologic correlations]. / Etude expérimentale de la conduction nerveuse et neuro-musculaire au cours de la plongée fictive chez le chien et le lapin: corrélations anatomo-pathologíques.

Five dogs and twelve rabbits were submitted to simulated diving at 6 ATA (compressed air) and 13-15 ATA (normoxic oxygen + nitrogen). Progressive decompressions were carried on for the first, rapid for the lasts. Motor nerve conduction velocity and nerve-muscle delays were measured. No variations could be observed neither for nerve conduction velocity nor for muscular and nerve action potentials. Nevertheless optic and electronic microscopy observations shew some nerve, neuronal and a few muscular alterations occuring during rapid decompression.
