Low prevalence of SARS-CoV-2 among patients presenting at a Parisian psychiatry University Hospital Group.

We examine the prevalence of SARS-CoV-2 infections among patients admitted to a Parisian psychiatric University Hospital Group (GHU). A total of 548 patients were admitted to the GHU...s full-time psychiatric wards between April 6 and May 3 2020. More than 80% were tested. A total of 7 patients tested positive for the SARS-Cov-2 (1.3%), with 5 patients (in 92, 5.4%) testing positive in the first week. GHU patients presented a low prevalence of SARS-CoV-2, even if all patients live in the hardest hit region in France. Social isolation and loneliness, as well as self-isolation of patients with symptoms could explain our results.

Internal hernia as a complication of congenital falciform ligament window.

Commonly, small bowel obstruction (SBO) is caused by either postoperative adhesions or external hernias. Internal hernias are rare, accounting for less than 2% of all cases of intestinal obstruction. An internal hernia through the falciform ligament is extremely uncommon and is usually secondary to a congenital or iatrogenic defect caused by trocars insertion. In this article, we report a case of SBO in a virgin abdomen that appeared to be caused by a congenital defect in the falciform ligament. A search of the literature was done identifying all reported cases of internal hernias caused by falciform ligament defect in order to guide diagnosis and management as well as avoidance of hernias caused by iatrogenic defects.

[Electrocardiographic evaluation of anti-ischemic effect of verapamil during angioplasty]. / Evaluation électrocardiographique des effets anti-ischémiques du vérapamil en cours d'angioplastie.

The anti-ischemic and cardioprotective effects of various angina drugs have been evaluated during angioplasty. This special situation of transitory regional ischemia was used to test verapami given by intra-coronary injection in 15 patients undergoing balloon dilatation of the left anterior descending artery, suffering from stable angina and with normal left ventricular kinetics. Each patient serving as his own control, parameters indicating oxygen consumption and clinical and electrocardiographic (ST segment changes) markers were measured during two successive inflations. Continuous monitoring of comparative variations between a first inflation without treatment and a second inflation after intra-coronary administration of 1 mg of verapamil revealed, following 60 seconds of ischemia, the absence of any change in heart rate, a moderate fall in mean blood pressure (101.7 as against 96.8 mmHg, p = 0.033) and a notable 60% reduction in the amplitude of maximal ST depression (5.07 +/- 3.08 mm as against 2.07 +/- 1.44 mm, p = 0.0002). These results confirm the anti-ischemic properties of verapamil, the action of which is based upon an indirect peripheral vasodilator model but also on a probable direct cardioprotective effect on anoxic myocardial regions.
