Changes in Tobacco and Alcohol Consumption in France during the Spring 2020 Lockdown: Results of the Coviprev and Viquop Surveys.

This study aims to describe changes in tobacco and alcohol consumption in France during the first COVID-19 lockdown in March 2020 and its gradual lifting in May. The associated factors and the reasons reported explaining those changes are also studied. Data came from five waves of the CoviPrev online cross-sectional survey (approximately n = 2000 per wave) and the ViQuoP qualitative survey (n = 60), which took place between April and June.

Barebacking and sexual health in the French setting: "NoKondom Zone" workshops.

Barebacking has been, since its emergence in the 1990s, a very controversial issue, and has as many definitions as authors writing about it. In France, sexual risk reduction strategies have been very contentious, and the advent of the bareback phenomenon increased this conflictual situation. This state of affairs has prevented the identification of needs and development of adequate programs for people not using condoms.

Primary cardiac lymphoma in an immunocompetent woman.

We report a fatal primary cardiac non-Hodgkin's lymphoma in a 62 years old immunocompetent woman presenting with tamponade and complete atrioventricular block. CT-scan, echocardiography and autopsy examination showed a tumor largely infiltrating the heart without extracardiac involvement. A surgical biopsy revealed high grade B-cell non-Hodgkin's lymphoma with a misleading myelomonocytic CD68 (KPI) expression.

[Role of echocardiography in the diagnosis of acquired diseases of the thoracic aorta].

The diagnosis and follow-up of acquired thoracic aortic disease have greatly improved with advances in transthoracic and transoesophageal echocardiographic techniques. In emergency situations, transoesophageal echocardiography is the key diagnostic investigation for dissection, significantly speeding up surgical referral. Atherosclerosis of the aorta is the second clinical situation in which transoesophageal echocardiography confirms its superiority over other imaging techniques for the recognition of intra-aortic debris carrying a high embolic risk.

[Local progression of atherosclerosis after optimal directional atherectomy. Endocoronary ultrasonography of 17 patients].

In vivo endovascular ultrasonography has confirmed the extension of atheroma to angiographically normal segments. The authors set out to determine by endocoronary ultrasonography if the introduction of the atherotome changed the intimal thickness 20 mm proximal and distal to the site treated. The area circumscribed by the external elastic layer (EEL) and the surface area of the lumen was measured in 17 patients: 1) before atherectomy; 2) after atherectomy; 3) at control 6 months later.
