Post-mortem toxico-kinetics of trazodone.

Trazodone is a structurally unique bicyclic anti-depressant, said to be significantly less toxic than other anti-depressants following an acute overdose. We studied the tissue distribution and post-mortem redistribution of trazodone in two fatalities, one of which allowed comparison with trimipramine, a typical tricyclic anti-depressant. Case 1, a 53-year-old female weighing 72 kg, had femoral vein concentrations of trimipramine 5.5 micrograms/ml, trazodone 14.4 micrograms/ml and alcohol 107 mg%. Case 2, a 48-year-old female of 70 kg, had a femoral vein trazodone of 15.5 micrograms/ml and alcohol 34 mg%, with no other drugs detected. For case 1 and case 2 respectively, trazodone tissue concentrations were: skeletal muscle 7.3 and 9.0 micrograms/g; left and right lungs 13.3, 12.9 and 35.3, 40.1; myocardium, 30.9 and 28.9; kidneys 34.7 and 39.6; liver 73.7 and 82.4; fat 18.5 and 16.5; brain 48.6 and 20.9. For case 1 and 2, respectively, blood trazodone concentrations in 10 initial autopsy samples ranged from 13.7-17.3 and 14.4-16.9 micrograms/ml. Twenty-four and forty-eight hours later the respective ranges were 12.8-18.0 and 12.4-19.9 for case 1, 12.5-20.1 and 12.7-27.0 for case 2. By contrast, for trimipramine, blood concentrations at 0 time, 24 h and 48 hours ranged from 5.5-11.4, 5.2-14.3, and 4.2-18.2, respectively. We conclude that trazodone shows little preferential concentration in solid organs and consequently has relatively stable post-mortem blood concentrations with little drug redistribution artefact. Both the clinical pharmacokinetics and post-mortem toxicokinetics of trazodone differ significantly from the tricyclic anti-depressants.     

What difference can they make? Assessing the social impact of corporate codes of practice

As retailers in the North increasingly adopt codes of practice containing social and/or environmental provisions in global supply chains, there is a need for rigorous assessment of their social impact. Moving beyond the rhetoric, it is important to establish the actual impact of such codes on poorer workers, their families, and other local stakeholders. This paper sets out the key methodological and conceptual issues arising in such an assessment as identified by a three-year study on the South African wine industry. It reviews the different motivations and approaches employed by code bodies, donors, academics, and practitioners, and highlights the lack of workers' voices in the debate on corporate responsibility as well as some of the early research findings. Finally, it explains how the inherent power inequalities in global supply chains make it more difficult to adopt a truly empowering approach to assessing the impact of codes of practice.     

Juvenile Delinquency in Switzerland Over 50 Years: Assessing Trends beyond Statistics

The general public seems to be convinced that juvenile delinquency has massively increased over the last decades. However, this assumption is much less popular among academics and some media where doubts about the reality of this trend are often expressed. In the present paper, trends are followed using conviction statistics over 50 years, police and victimization data since the 1980s, and self-report data collected since 1992. All sources consistently point to a massive increase of offending among juveniles, particularly for violent offences during the 1990s. Given that trends were similar in most European countries, explanations should be sought at the European rather than the national level. The available evidence points to possible effects of increased opportunities for property offences since 1950, and although causality remains hard to prove, effects of increased exposure to extreme media violence since 1985Swiss conviction statistics are based on registration in the national register of convictions. After 1971, minors were registered only in exceptional cases (Balvig 1988, p. 30)
