Acute myoglobinuria as a fatal complication of heroin addiction   总被引:3,自引:0,他引:3  
A fatal case of myoglobinuria complicating heroin addiction is described. Clinically the patient had no overt symptoms of rhabdomyolysis. Pathologists should be alerted to this rare complication in heroin addicts who die of no apparent cause. The antimyoglobin immunoperoxidase technique is useful in confirming the diagnosis.  相似文献

The conventional wisdom in criminology is that adult onset of offending is a rare event. Closer examination of the extant literature that use official records, however, reveals that an average of 50 percent of adult offenders initiate offending at age eighteen or older. Although criminological research has investigated late onset offending in adolescence, there is little research on adult onset offending and the correlates of adult offending. Using police contact and interview data from the 1942 and 1949 birth cohort data from Racine, WI, this study investigated the correlates of crime for adult onset and persistent offenders. The results show that employment is the only correlate to affect the probability of adult offending differently for previously delinquent and nondelinquent offenders. This article concludes by highlighting the neglect of research on adult offenders, specifically the large percentage of adult onset offenders, and calling for more research on this topic.  相似文献

This paper uses historical content analysis to examine the implementation ofthe Racketeer Influenced Corrupt Organizations Act (RICO). It is argued thatthe historical events leading to the definition of organized crime as an alienconspiracy still affect RICO's use some 30 years after its passage. This paper applies state-centered theory to the theoretical frameworks of sociology of knowledge and innovation diffusion. This approach is used to relate the current implementation and controversy of RICO to the alien conspiracy view. Thought of in this context, legal implementation is the result of a knowledge creation and diffusion process. This paper demonstrates how one knowledge diffusionprocess (the acceptance of organized crime as a national conspiracy in 1970) leads to a new knowledge diffusion process (the use of RICO).  相似文献

This article provides an editorial introduction to the following three related articles on the growing use and influence of social science research in family law. It first considers why this has become problematic and identifies some common strategies used by advocates, sometimes under the guise of scholarship, to destroy the standing of research findings contrary to their ideological or political position. Then it discusses briefly the remedies proposed to mitigate these kinds of problems within the following three articles.  相似文献

From a conflict resolution perspective, it is clear why the child support guidelines are not going to reduce the adequacy and compliance gaps in child support payment conflicts between parents. As it stands, the conflict over equally sharing child support is destructive rather than positive. The guidelines do not reframe the conflict for the parents, enabling them to believe the interests of children are more important than their own interests to win the child support battle. To transform conflict from destructive to positive, the elements of conflict–expression of the conflict, scarce resources and rewards, and interdependency–must be transformed. It is argued that the guidelines do not transform the conflict but facilitate it. Courts and attorneys are also significant players in the child support conflict.  相似文献

A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning.  相似文献
