Community violence and PTSD in selected South African townships

Given the high rates of crime in South Africa's townships, nonpolitical violence out-side the home and its psychological impact on women were investigated within two samples, the primary a help-seeking sample and the secondary a community sample. In the help-seeking sample, two thirds of the women reported having experienced several traumatic events outside the home. Those women displayed a median of 9 PTSD (post-traumatic stress disorder) symptoms, with nearly half meeting all criteria for PTSD. In the community sample, 40 women of color were interviewed at a community festival for women, and again two thirds reported having experienced several traumatic events outside the home during the previous year. These women displayed a median of 8.8 PTSD symptoms, with none meeting all criteria for PTSD. South Africa's distinctive culture of violence is discussed as context for understanding issues of community violence and PTSD among women in its minority townships.     

MOR1 receptor mRNA expression in human brains of drug-related fatalities-a real-time PCR quantification

The expression of the human micro-opiate receptor (MOR1) in post mortem human brain tissue was examined using real-time PCR technology. Tissue samples from 11 fatalities due to opiate overdose and five normal subjects with different causes of death were analysed in order to elucidate whether chronic opiate abuse is followed by a regulation of MOR1 expression. In each case nine selected brain regions (thalamus, caudate nucleus, hypothalamus, ventral tegmentum, hippocampus, amygdala, frontal cortex, nucleus accumbens, putamen) were evaluated. The MOR1-mRNA level was determined relative to the housekeeping gene beta2-microglobulin. While in most regions the MOR mRNA levels in the brain of addicts were not different from the control group-with varying levels between 0 and 15% of housekeeping gene level-in the brains of three drug-related fatalities an enormous increase was encountered in the thalamus where the MOR-mRNA level amounted for up to 10,000% of the measured housekeeping gene level. The results obtained by toxicological hair analysis in the group of drug-related fatalities indicate that the enormous thalamic MOR1-expression is primarily found in individuals who died from acute heroin overdose but did not show signs of a substantial chronic administration of the drug. Further studies have to be performed to evaluate if the observed MOR1-mRNA up-regulation in the thalamus in a subpopulation of acute lethal intoxications mirrors a state of functional hypersensitivity associated with the occurrence of death.     

The effect of oleoresin capsicum "pepper" spray inhalation on respiratory function

We performed a randomized, cross-over controlled trial to assess the effect of Oleoresin capsicum (OC) spray inhalation on respiratory function by itself and combined with restraint. Thirty-five subjects were exposed to OC or placebo spray, followed by 10 min of sitting or prone maximal restraint position (PMRP). Spirometry, oximetry, and end-tidal CO2 levels were collected at baseline and throughout the 10 min. Data were compared between groups (ANOVA) and with predefined normal values. In the sitting position, OC did not result in any significant changes in mean percent predicted forced vital capacity (%predFVC), percent predicted forced expiratory volume in 1 s (%predFEV1), oxygen, or CO2 levels. In PMRP, mean %predFVC and %predFEV1 fell 14.4 and 16.5% for placebo and 16.2 and 19.1% for OC, but were not significantly different by exposure. There was no evidence of hypoxemia or hypercapnia in either groups. OC exposure did not result in abnormal spirometry, hypoxemia, or hypoventilation when compared to placebo in either sitting or PMRP.     

Cyanide fatalities: case studies of four suicides and one homicide

Deaths due to cyanide poisoning are relatively rare, largely owing to the restricted availability of cyanide. Nevertheless, the authors report five cases of cyanide fatalities occurring within a few months. Cyanide is one of the most rapidly acting poisons known and is still used for suicide and homicide. The discussion focuses on the circumstances, metabolic changes, pathophysiology, blood levels, diagnosis, and management of cyanide poisoning.     

Trade ‘outside the law’: Uzbek and Afghan transnational merchants between Yiwu and South-Central Asia

ABSTRACT

This article analyses the trajectories of two transnational networks present in the Chinese city of Yiwu: Afghan merchants who trade goods in and out Afghanistan, Tajikistan and Pakistan; and Uzbek traders (citizens of either Tajikistan or Uzbekistan) who commercialize their merchandise in and out Tajikistan, Uzbekistan and Russia. Our aim is to capture an ethnographically grounded understanding of informal markets and economies by analysing the notion of trade ‘outside the law’, including the contested yet widely used category of the ‘smuggler’. By paying attention to the fluidity of trading practices ‘outside the law’, we also address the uses and limitations of metaphors widely used in scholarly analysis of informal markets: notably those of ‘lower’ and ‘higher’ forms of globalization, and the transposition of formal-legal and informal-illegal exchanges onto the notions of economic ‘centres’ and ‘peripheries’.     

Differentiation between self-inflicted and homicidal stab wounds to the neck

39 autopsy cases with throat incision examined in the Bonn Institute of Legal Medicine in the years 1990 through 1998 were evaluated with respect to the query whether the morphological criteria generally established for the differentiation between homicide and suicide are also suitable for the assessment in this special localization. Integrative consideration of localization, direction of incision, hesitative resp. tentative injuries, defence injuries, concomitant injuries and capability to act allowed for a discrimination on grounds of legal medical findings in 84 per cent of the cases.
