The impact of antiphospholipid antibodies (APA) on clinical outcome and graft histology following renal transplantation remains poorly known and controversial. We retrospectively explored the functional and histological significance of APA, primarily lupus anticoagulant (LA), in kidney transplant recipients using a systematic evaluation of 3-and 12-month posttransplant screening biopsies and glomerular filtration rate measurements (mGFR). During the study period, 37 patients had APA (2.7%), primarily LA, and 12 fulfiled antiphospholipid syndrome (APS) diagnostic criteria (0.8%) at the time of transplantation. Early after transplantion, 4 of the 12 APS patients died. Early thrombosis of graft vessels and deep venous thrombosis occurred more frequently in APA+ patients than in controls (27% vs. 7%, p < 0.05 and 35% vs. 14%, p < 0.05, respectively). The survival rate was significantly lower in patients with APS. Strikingly, the hallmark lesions of APS-associated nephropathy (APSN) were found in most of screening graft biopsies in APA+ patients but not in the controls. Accordingly, APA+ patients had a dramatic increase in chronic vascular scores and a faster decline in mGFR at 1 year. In conclusion, renal transplantation may be life-threatening in APS patients, and the presence of LA at the time of transplantation is associated with a high rate of allograft APSN and poor transplantation outcomes.

In the present study two broad hypotheses about the origins of self-mutilation in psychiatric patients were evaluated. The first hypothesis states that self-mutilation originates from child abuse and experiences of neglect and is connected to dissociation in later life. The second hypothesis views self-mutilation as the consequence of impulse control problems. To test these two hypotheses, data concerning traumatic childhood experiences and dissociative symptoms (hypothesis 1), as well as data concerning aggressiveness, obsessive-compulsiveness and sensation seeking (hypothesis 2) were collected in a sample of 54 psychiatric inpatients. Twenty-four out of 54 patients (44%) reported having engaged in self-mutilation. Mean age of onset of this behaviour was 23 years. Self-report measures of self-mutilators were more in line with the first than with the second hypothesis. That is, patients who engaged in self-mutilation reported more traumatic childhood experiences and dissociative symptoms than did control patients. The two groups did not differ in terms of aggressiveness, obsessive-compulsiveness, and sensation seeking. In line with earlier studies, the current results indicate that self-mutilating behaviour is linked to a history of abuse and neglect.

Objectives: To explore if the dramatic decrease in price of e-cigarette has transformed this new product into a product used for tobacco initiation among a teenage population. Methods: The authors added a question in 2012 on e-cigarette in the yearly survey on tobacco consumption in Paris schoolchildren. The study is conducted on a randomly selected sample from 2% of classes since 1991. Results: 277 (8.1%) of the 3409 schoolchildren studied (including 575 non responders to this question) reported having had an experience with e-cigarette. Experimentation rate is 6.4% among the 12-14-year-old, 11.8% among the 15-16-year-old and 9% among the 17-year-old schoolchildren. Among the 12-14year-old schoolchildren, 64.4% of e-cigarette experimentation was by non-smokers. Of the 17-year-old teenagers who had used e-cigarettes, 12.4% were non-smokers. For the whole population, 33.2% of those having tried e-cigarette are non-smoker, 22.7% occasional smoker, 3.6% ex-smoker and 40.4% daily smoker. Those who experiment cannabis, shisha or binge-drinking are more frequently users of e-cigarette. In the smoker group, there is an inverse trend of relationship between the readiness to quit tobacco and the rate of use of e-cigarette. Conclusion: For teenager's, e-cigarettes have become not a product to aid quit tobacco but a product for experimentation and initiation of cigarette use. Regulation is urgently needed to control the emergent use of this new tobacco product by children.
