Volume et profil de consommation d’alcool des élèves et des camarades scolaires comme prédicteurs de l’agression et de la victimisation: une analyse multiniveaux auprès d’adolescents suisses

Volume and profile of alcohol consumption among students and classmates as predictors of aggression and victimization: a multilevel analysis among Swiss adolescents

Objective:  

To test the effects of the volume of alcohol consumption and drinking patterns on alcohol-related aggression and victimization, both at the individual and class levels.     

The distally based sural fasciomusculocutaneous flap for foot reconstruction.

Finding appropriate soft-tissue to cover a wound located over the middle or distal portion of the foot can be challenging. A distally based sural fasciomusculocutaneous flap including the sural nerve and a midline cuff of the gastrocnemius muscle can be used for this purpose. This flap is designed on the proximal third of the posterior calf and is nourished in a retrograde manner by the lower peroneal septocutaneous perforators, through the vascular axis of the sural nerve to the musculocutaneous perforators of the gastrocnemius muscle. Between October of 2002 and January of 2004, this flap was applied in nine individuals, including four diabetic patients. The skin defects all resulted from trauma, osteomyelitis or chronic ulcer, and combined with bone or tendon exposure. One flap developed distal necrosis. The other flaps survived fully and provided good contour. In our series, diabetes mellitus seemed not to compromise the vascularity of the flap. The distally based sural fasciomusculocutaneous flap is very useful for lower limb reconstruction, particularly for the foot, because of its long vascular pedicle and the availability of the skin portion of the proximal calf based on direct branches between the musculocutaneous perforators and the neurovascular axis of the sural nerve. This is an important variant of the sural neurocutaneous flap and it appears to be a good alternative to free flaps for resurfacing the foot.     

Structural shielding design for a gamma ray stereotactic body radiotherapy system.

An OUR-QGD gamma ray stereotactic body radiotherapy system (body knife), made in China, is described. According to its structure and the principle of gamma radiation revolved on a focus, the energy distribution of scattered radiation in its treatment room is calculated. The structural shielding of the wall, roof, and door for a certain treatment room is calculated according to the local radiation protection law.     

试论"自甘风险"原则在审理医疗侵权纠纷案件中的应用

公正的、客观的、完善的法律制度,是调整医患法律关系,规范医疗行为,保障医患双方合法权益的客观需要。随着我国法制建设的迅速发展,目前,患者越来越需要懂得依法维护自己的生命健康权利;医生越来越需要懂得依法进行诊疗,依法履行义务,依法维护自己的切身权利和利益;社会越来越需要有公正健全的法律制度。我国卫生法学领域的“新生代”正是在这种情况下应运而生的。各地涌现出一批兼有医学和法学双学历、勤勉好学、勇于探索、热衷于卫生法学研究的年轻人,将来必有建树。本刊《医与法》栏目就是他们及时发表睿见的一个园地,欢迎来稿。
