[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.

[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.
