Clinicopathologic features of fatal self-inflicted incised and stab wounds: a 20-year study

The files of the Forensic Science Center in Adelaide, South Australia, were examined for all cases listed as suicide in which death had been caused by the use of a sharp instrument during the 20-year period from January 1981 to December 2000. Fifty-one cases were identified, consisting of 35 men and 16 women. The age range was 23 to 83 years (mean 49 years) representing 1.6% of total suicides (513182). Fatal injuries included incised wounds to the arms in 51.4% of men (n = 1835) compared with 87.5% of women (n = 1416), incised and stab wounds to the neck in 40% of men (n = 1435) and 25% of women (n = 416), and stab wounds to the chest or abdomen in 28.6% of men (n = 1035) and 12.5% of women (n = 216). In 8 cases, multiple sites were involved. The use of sharp instruments in suicide was favored by older, rather than younger, individuals, with a tendency for women to incise their wrists. Hesitation marks were present in 23 cases (54%) and scarring of the wrists from previous suicide attempts in 5 cases. Although this study demonstrated a higher number of men than women committing suicide by using sharp objects, this method of suicide remains uncommon.     

A case of sudden death from primary intracranial germinoma complicated by microvascular disease of the heart

A coroner's autopsy conducted on an 11.5-year-old girl, with a history of hypopituitarism, manifesting as growth hormone deficiency associated with short stature, demonstrated the presence of an undiagnosed hypothalamic intracranial germinoma, showing hypophyseal and mesencephalic invasion, together with histological evidence of microvascular (small coronary artery) disease of the heart. The substantive, or primary, cause of her sudden death was clearly the intracranial germinoma, which was acutely haemorrhagic and necrotic. However, it is postulated that there might be an, as yet, undescribed association between this malignancy and the pathogenesis of the coronary microvascular disease; the latter being deemed, in this instance, to be a contributory cause of death.     

Seriousness of crimes: A survey of the nation's chiefs of police

The views of 105 police chiefs throughout the United States were obtained in regard to their ranking of the seriousness of 60 criminal offenses. Responses indicated that the chiefs see most crimes very much in the same light as do citizens surveyed by Rossi et al. (1974) in Baltimore a decade ago. There also is considerable consensus among chiefs throughout the country in their views about seriousness. Variations between the present findings and those of similar studies of other populations are also set forth.     

Social Competence and Substance Use Among Rural Youth: Mediating Role of Social Benefit Expectancies of Use

The present study examined the mechanisms by which social competence may be associated with substance use during early adolescence. The sample consisted of rural youth (N = 1,568) attending 36 junior high schools in a midwestern state. Structural equation modeling indicated that social competence had a direct protective association with substance use in that those youth who were more socially confident, assertive, and had better communication skills reported less smoking and drinking. Further analyses revealed that the relationship between social competence and substance use was fully mediated by social benefit expectancies of use. These findings suggest that poorly competent youth turn to smoking and alcohol use because they perceive that there are important social benefits to doing so, such as having more friends, looking grown up and cool, and having more fun. Prevention programs that teach youth interpersonal skills may reduce the initiation of substance use by improving social competence and providing youth with more adaptive means of gaining approval from peers.     

Bacterial Translocation and Sample Contamination in Postmortem Microbiological Analyses

The diagnostic value of postmortem bacteriology has been discussed controversially for decades. In the study herein, contamination during sampling procedures and postmortem translocation were investigated to interpret postmortem microbiology results. One hundred medicolegal autopsy cases in total were included. Radiology, histology, bacteriology, and biochemistry were performed in all cases. Based on all investigation findings, 4 groups of cases were identified: death unrelated to infection, true infections, false positive (contamination during sampling procedures, postmortem translocation and mixed situations), and undetermined. The results of this study indicate that postmortem bacteriology provides useful data supporting infection‐related deaths, especially when potentially significant observations are accompanied by consistent autopsy, histology, and biochemistry. Result interpretation requires careful evaluation of number and type of isolated microorganisms.
