Cause of death rulings in cases when the concentration of a drug or drugs is higher than observed following therapeutic use are generally straightforward “drug deaths.” However, when toxicology testing identifies drug concentrations consistent with therapeutic use or detects no drugs at all, then the cause of death determination is more complicated. Given the rapidity and protean manifestations of anaphylaxis, it should be considered in deaths where no other cause of death is apparent in a suspected drug death. This article reports two cases where an anaphylactic reaction was observed following either the actual or alleged use of therapeutic formulations of buprenorphine intravenously.  相似文献

The Office of the Chief Medical Examiner of Maryland recorded a total of 149 drug abuse deaths of teenagers aged 13-19 years between 1991 and 2006. Of these deaths, 96 (64.4%) were caused by the use of narcotic drugs only, 29 (19.5%) by both narcotics and cocaine, four (2.7%) by both narcotics and methylenedioxymethamphetamine, six (4.0%) by cocaine only, and 14 (9.4%) by volatile substances (e.g., butane, Freon, nitrous oxide, and propane). The annual death rate from drug abuse for teenagers increased from 1.4 deaths per 100,000 population in 1991 to 2.7 deaths per 100,000 population in 2006 (chi-square test for time trend, p<0.01). The increase in teenager drug abuse deaths occurred in 1999 and since has remained at a higher rate. Further analysis revealed that the increase in drug abuse deaths was attributable to a large degree to narcotic drugs, particularly heroin/morphine and methadone, and was confined to teenagers residing in the suburban and rural areas.  相似文献

This article explores accounts of bystanders to female-on-female public violence. Group interviews with participants in the night-time economy are carried out. Whereas men tend to respond to the discussion topic of female-on-female violence with laughter, this laughter reveals ambivalence and discomfort as much as amusement. Men seem to negotiate the tension between the expectation that they should intervene in emergencies and a catalogue of costs that attend intervention. Female bystanders appear to have a different set of concerns. They talk about feelings of shame at the interpersonal and the group level. Women cite the public spectacle, and the opportunity for men to demean or sexualize women, as reasons for intervention. The article concludes with some recommendations about the importance of exploring female violence in its own terms, beginning with a series of identified moral and social dilemmas incurred within possible third-party intervention.  相似文献
