Three cases are described in which deaths after motor vehicle accidents occurred as a result of positional asphyxia associated with exposure to gasoline. The deceased individuals were aged 16, 34, and 35 years, respectively (M:F = 1:2) and had all been in the back seat of motor vehicles involved in rollover accidents that had resulted in spilling of gasoline with contamination of the cabins. Major components of gasoline were detected in blood and tissues by headspace gas chromatography. Postmortem toxicologic investigations of such cases, which include analyses for volatile hydrocarbons, may therefore produce additional significant information. 相似文献

The deaths of two children who were passengers in motor vehicles involved in accidents were directly attributable to vascular injuries derived from seat belts. In the first case, a 10-year-old boy died as a result of abdominal aortic transection by a lap seat belt, and in the second case a 15-year-old boy died as a result of transection of his common carotid artery by a lap-shoulder seat belt. Although these cases demonstrate rare fatalities associated with seat belt use, there is no doubt that seat belts have significantly reduced mortality and morbidity from traffic accidents. Although it is possible that a fatal outcome might have occurred in each of these cases from other injuries that might have been sustained had seat belts not been worn, appropriate positioning and size of seat belt harnesses might have avoided the lethal injuries. 相似文献

A retrospective study of cases of drowning suicide was undertaken at the Forensic Science Centre in Adelaide, South Australia for the period April 1980 to March 2000. A total of 123 cases were found, with 76 males (age, 16-88 years; average, 50.5 years; standard deviation [SD], 20.1 years) and 47 females (age, 34-88 years; average, 60.6 years; SD, 13.9 years). There were 66 fresh water drownings and 57 saltwater drownings. Female victims were significantly older than male victims for both fresh water and saltwater drownings (P < .05 and P < .01, respectively). Deaths in young women were rare. No temporal trend in drowning suicides could be shown, with annual numbers varying from 0 to 12 cases (average, 6.15; median, 7). Women preferentially chose the ocean or bath to drown themselves in, whereas males chose rivers, ditches, and lakes. Swimming pools were rarely used for suicide in this population; alcohol use was not usual; and there was often a significant history of mental illness. 相似文献

Three cases of traditional punishment in Central Australian Aboriginal men are presented in which the thighs were speared or stabbed as part of a "payback" system. In two cases, an unexpected effect of the stabbing or spearing was death due to severing of major leg vessels. The relationship between customary Aboriginal law and general law in Australia has not been clearly defined; however, these cases demonstrate that significant and untoward effects may result from traditional punishments. Pathologists working near traditional Australian Aboriginal communities may still encounter such injuries at autopsy. 相似文献
