[Attitudes and behavior in relation to smoking among medical students in Casablanca in 2010]. / Comportement des étudiants en médecine de Casablanca vis-à-vis du tabac en 2010.

OBJECTIVE: Smoking is a major public health problem. The doctor should be at the forefront in the fight against tobacco. Our study aims to determine the prevalence of smoking among medical students and to evaluate their attitudes towards this problem. PATIENTS AND METHODS: A cross-sectional survey was conducted among 736 medical students enrolled in the faculty of medicine and pharmacy of Casablanca in the academic year 2009/2010. RESULTS: The prevalence of smoking was 7.9%. It was significantly higher in men (16% against 3% in women) and varied little from one age group to another (7-8%). The average number of cigarettes smoked per day was eight. More than half of the students (58%) had attempted to quit smoking. The main motivation was the occurrence of certain symptoms (66%). Ex-smokers accounted for 10% of the total. Moroccan anti-smoking law was poorly understood by more than half of our students (72%). The majority was in favor of prohibition of tobacco sales to children (92%) and the training of health professionals to help patients who want to quit smoking (86%). CONCLUSION: Compared with previous years this study shows a marked decrease in the prevalence of smoking among medical students in Casablanca as well as a better understanding of its ill effects. This is due not only to greater awareness of this problem among medical students but also to the introduction of the teaching of the pathologies related to tobacco.

[Cardiac thrombosis, pulmonary artery aneurism and pulmonary embolism revealed Behçet's disease]. / Thrombose cardiaque, anévrisme de l'artère pulmonaire et embolie pulmonaire révélant une maladie de Behçet.

Intracardiac thrombosis is a rare complication of Behçet's disease. It may be isolated or associated with arterial disease. We report a case of a patient from northern Morocco, aged 23, without specific medical history. He consulted for recurrent hemoptysis of middle abundance, associated with bipolar aphthosis. Chest radiography showed a left basal opacity fuzzy and right paracardiac opacity. The thoracic CT objectified left segmental lower lobe embolism, an aneurysm of a segmental branch of the right lower lobe and right intraventricular thrombus. Echocardiography confirmed the intracardiac thrombus. The patient was treated by oral corticosteroids, azathioprine, colchicine, and anticoagulants. The outcome was favorable with complete resolution of intraventricular thrombus and the aneurysm.
