Objective - We report the results of a survey among medical students in the Strasbourg medical school, including questions standard precautions, prevention of blood exposure accidents, methods usually applied, and circumstances of blood exposure accident they may have been victims of. Design - Anonymous questionnaire forms were handed out to second, third, and fourth year medical students. Results - Thirty per cent of third and fourth year student who already have an experience in clinical practice described blood exposure accident during their hospital training. Suture was the most frequent accident circumstance described (45%), blood drawing for gas measurement was the second (24%). Only 45% of these accidents were reported but serology control was performed in 71% of the cases. Students were questioned on the use of gloves during invasive medical care, 50% of them did not use any protective gloves. Sixty seven per cent of students resheathed needles, and only 30% personally disposed of needles in special containers. Conclusion - The incidence of blood-exposure accidents in hospital medical students is high. Measures should be rapidly implemented to inform and train students on prevention and to teach them safe technical procedures.

Objectifs - Nous proposons les re´sultats d'une enque^te re´alise´e chez les e´tudiants en me´decine de Strasbourg a` propos de leurs connaissances des pre´cautions standard, leurs habitudes dans le domaine de la pre´vention des accidents d'exposition au sang (AES) et des AES dont ils ont e´ventuellement de´ja` e´te´ victimes. Patients et me´thodes - Un questionnaire anonyme est remis aux e´tudiants en me´decine des 2, 3 et 4 anne´es du second cycle des e´tudes me´dicales, au cours de la re´union des choix de stage. Re´sultats - Trente pour cent des e´tudiants de DCEM 3 et 4 signalent avoir e´te´ victime d'un AES a` l'occasion de soins qu'ils donnaient au cours d'un stage clinique. Les sutures sont a` l'origine de la plupart de ces accidents (45 %) puis la ponction arte´rielle pour gaz du sang (24 %). Seulement 45 % de ces accidents sont de´clare´s, mais 71 % des e´tudiants feront une surveillance se´rologique post exposition. Paralle`lement, les e´tudiants sont interroge´s sur le port de gants lors de la re´alisation des gestes invasifs (pre`s de 50 % n'en portent pas). Les aiguilles utilise´es sont encore trop souvent recapuchonne´es avant d'e^tre e´limine´es (67 % des e´tudiants le font «toujours » ou «souvent ») et le conteneur a` aiguille n'est utilise´ que par 30 % des personnes interroge´es. Conclusion - Les AES chez les e´tudiants sont particulie`rement fre´quents. Un effort d'information et de sensibilisation des e´tudiants en me´decine est ne´cessaire afin que le geste technique se´curise´, tant pour le soignant que pour le patient, soit enseigne´.

Asbestos fibers were counted by using the transmission electron microscope in 42 wines from France and abroad. Fifteen samples were found to be significantly positive for chrysotile asbestos. Concentrations were in the range of 2-64 × 106 fibers per liter. Technical Investigations showed that the asbestos content of the wines was related to the process by which they were filtered. On the other hand, we found that abandoning the use of asbestos for filtering wines would not alter the wine from the enological point of view.
