Changes in composition of endoneurial and perineurial fatty acids during glycerol-induced Wallerian degeneration and regeneration in the sciatic nerve of the adult rat.

Intraneural injection of pure glycerol induces Wallerian degeneration with subsequent regeneration. In agreement with other reports, we observed an increase in endoneurial polyunsaturated fatty acids 8 days after the glycerol injection. Levels then fell until day 30. After a period of 5 months, there was an increase in C18:2(n-6) in the intrafascicular tissue, concomitant with a marked fall in this fatty acid in the remaining extrafascicular perineurium. The rise in C18:2(n-6) in endoneurium correlated with infiltration of this tissue by perineurial cells. Interactions between perineurium and endoneurium during nerve regeneration are discussed.

[Hepatic involvement in secondary syphilis].

A case of secondary syphilitic hepatitis is reported. A 49-year old woman was admitted for weight-loss, fever, hepatomegaly and splenomegaly. Diagnosis of syphilitic hepatitis was based on cholestasis associated with positive serologic tests for syphilis without other immunological disturbances. Biopsy of the liver showed a moderate infiltration in and around the portal tracts. Immunofluorescence study for treponema was negative. Rapid improvement was obtained with penicillin initially associated with steroid therapy. Liver involvement in secondary syphilis is characterized by anicteric cholestasis, an inflammatory syndrome, and periportal infiltrate inconstantly associated with centrilobular necrosis, granulomatous reaction and presence of treponemas in the lesions. Due to the increasing frequency of sexually transmitted diseases, this diagnosis could become more frequent.

[Myxedema coma with hypervasopressinism. 2 cases].

Hyponatremia is usual during myxedema coma. Hereafter we report two cases with increased plasma arginine vasopressin (AVP). Patients were admitted because of hypothyroid coma. In each case, there was an hyponatremia with normal urine sodium and low serum osmolality. Renal function was normal. On hormonal results, primary hypothyroidism was evident. Plasma AVP was increased. The plasma cortisol of one patient was high. Immediate therapy associated: water restriction, hypertonic saline infusion, furosemide, oral thyroid hormones with low doses. On the fourth day, conscience improved obviously. Natremia and plasma AVP went back to normal state before returning to euthyroid state. Patients went on improving along with normalizing thyroid status. Hyponatremia can be a serious sign of hypothyroidism. In case of myxedema coma with hyponatremia, clinical improvement seems to be related to fast correction of water and electrolyte disturbances and we prefer to give low doses of thyroid hormones at first. The hyponatremia and increased plasma AVP mechanisms are complex. However, in each of these cases, plasma AVP come back to normal before returning to euthyroid state. In one case, high plasma cortisol level rules out adrenal insufficiency as causal mechanism of electrolyte disorders.

Myasthenia gravis associated with adrenocortical insufficiency. Report of two cases.

Two cases of Addison's disease associated with myasthenia gravis are reported. This association has been described only rarely in the literature. In the first case, there were marked immunological abnormalities. It is most likely that the origin of the adrenocortical insufficiency in the second case is tuberculous. The pathogenetic mechanism of these associations is briefly discussed.

[Hyperthyroidism and mitral valve prolapse: comparative two-dimensional echocardiography study of a hyperthyroid and a control population totalling 104 patients].

Recent studies seem to demonstrate a higher incidence of mitral valve prolapse in hyperthyroid patients. A complete cardiological check-up including 2D echocardiography was performed in 52 hyperthyroid patients and 52 control subjects. In the hyperthyroid population, mitral valve prolapse was diagnosed 3 times, 5,8 p. 100 of cases. These 3 subjects were female; hyperthyroidism was nodular in 2 cases: Grave's disease was only present in 1 case. Hyperthyroidism was very active at the time of the echocardiographic study in those 3 patients. In the control group, mitral valve prolapse was observed in 4 cases (7.7 p. 100). These 4 patients were all female. The results of this study do not show a higher incidence of mitral valve prolapse in the hyperthyroid population than in the control group. Grave's disease was not more prevalent in hyperthyroid patients with mitral valve prolapse. On the other hand, there were significantly more female patients with MVP in both the hyperthyroid and control populations.

[Acute ischemia of an arm manifesting Buerger's disease. Predisposing role of anorexia nervosa].

Peripheral vasomotor disorders, notably acrocyanosis, are frequent in anorexia nervosa, but ischaemic accidents are unknown. We report the case of a 32-year-old woman with a 10-year history of anorexia nervosa, who developed acute ischaemia in one of her upper limbs. In this particular case several aetiological factors may be considered: Buerger's disease, of course, as the patient smoked and had an abnormal arteriography, but also hypercholesterolaemia, thrombocytosis and disorders of platelet aggregation.
