A new set of data concerning the pattern of suicide in India between 1991-1997 are presented. Suicide rates rose over this period despite a small decline in the Indian suicide rate in 1995 and 1996. It was found that between 1995 and 1997 there was a modest fall in the suicide rates among under 29-year-olds of both sexes, and an increase among those 30 years and older. The pattern of suicides in India is bimodal: the incidence of suicides is highest for those in the 30-44-year-old category of both sexes and tends to decline in higher age categories. Suicide rates were nearly equal for young women and men, a contrast with the pattern of suicide sex ratios in eight developed countries. 相似文献

OBJECTIVE: To describe the death of a toddler after a therapeutic dose of dextromethorphan and its investigation. STUDY DESIGN: Case report, cytochrome P450 phenotype and genotype determination in the victim and post-mortem drug redistribution study performed in rats. RESULTS: A 20-month Asian male who received 3 mg of dextromethorphan once at 09:00 h and again at 22:00 h was found dead at 04:35 h. Post-mortem examination showed signs of early bronchopneumonia (bacterial cultures were negative); dextromethorphan and dextrorphan blood concentrations taken from the heart cavity were 500 ng/ml (1. 84 micromol/l) and 200 ng/ml (0.78 micromol/l), respectively. Despite the dextromethorphan level being almost 100-fold higher than expected after therapeutic doses, intentional or unintentional overdose was extremely unlikely; other potential causes were investigated. Post-mortem drug redistribution study performed in rats showed that dextromethorphan does not undergo extensive redistribution after death (6+/-5-fold increase) and could not explain the observed dextromethorphan level. The dextromethorphan/dextrorphan concentration ratio of 2.5 found in this toddler was compatible with a slow CYP2D6 metabolizer phenotype. However, the toddler exhibited a fast metabolizer genotype. Potential reasons for this discrepancy are discussed. CONCLUSION: CYP450 phenotypes derived from post-mortem blood levels should be interpreted with caution and preferably confirmed by a genotype analysis. 相似文献

Student peer aggression has become an issue of considerable concern in schools and their surrounding communities. While a considerable volume of research and writing now exists on how this problem might be best managed, little has been written concerning the place of law in the management process. Nonetheless, in view of the long term effects of student peer aggression on both aggressors and aggressed, it behoves school administrators and teachers to have a sound awareness of the many issues associated with this form of behaviour. In particular it is advisable for staff to have a sound appreciation of the potential legal repercussions that can be the result of a failure to exercise an appropriate level of the duty of care owed to students in relation to peer aggression. This article examines recent research into student peer aggression in Australia and elsewhere. Reasons advanced to explain this form of behaviour are discussed, the characteristics of aggressors and aggressed examined, and consequences of student peer aggression explored. The legal remedies available are identified and discussed and measures needed to manage the problem are suggested. 相似文献
