[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.

Personality pattern of patients with chronic gastric ulcer. Study of neuroticism and extroversion in a gastric ulcer and a control population.

Forty-four patients with chronic gastric ulcer were compared with a control group matched for age, sex, and place of residence. The personality pattern was studied by the Eysenck Personality Inventory and personality assessed in terms of neuroticism and extroversion. The relevance of social class was also studied. The gastric ulcer population did not differ from the control group except among the male population, in which the gastric ulcer population was significantly more neurotic and less extroverted than their controls.
