Post-mortem cases involving amphetamine-based drugs in The Netherlands. Comparison with driving under the influence cases

In this study we reviewed the post-mortem cases in the years 1999-2004 that were presented at the Netherlands Forensic Institute. The concentrations of amphetamine-based drugs in femoral blood from cases of suspected unnatural death were compared with concentrations in whole blood from non-fatal cases of driving under the influence (DUI cases) and with literature. Furthermore, the combinations with other drugs and/or alcohol were investigated. Amphetamine-based drugs were present in 70 post-mortem cases and 467 DUI cases. The most detected amphetamine-based drug was MDMA, followed by amphetamine. The presence of MDA could usually be explained by metabolism of MDMA. Methamphetamine and MDEA were rarely present. Frequently, the amphetamine-based drugs were taken in combination with alcohol and/or other non-amphetamine-based drugs such as cocaine or cannabinoids. The 70 post-mortem cases were divided into 38 amphetamine-based drug caused (i.e. the amphetamine-based drug directly caused or contributed to the death) and 32 amphetamine-based drug related deaths (i.e. death was not directly caused by the amphetamine-based drug). In the latter category, other (poly)drug intoxications and death by violence or drowning were the most frequent causes of death. In 30 cases, MDMA caused death directly. The range in blood concentrations of MDMA in these cases was substantial, i.e. 0.41-84 mg/L with a median concentration of 3.7 mg/L (n=30). MDMA blood concentrations in the MDMA related deaths (n=20) and in the DUI cases (n=360) varied up to 3.7 and 4.0 mg/L, respectively. Seven victims died from the direct effects of amphetamine; the blood concentration of amphetamine ranged from 0.24 to 11.3 mg/L, with a median concentration of 1.7 mg/L (n=7). The median concentrations of amphetamine in the amphetamine related deaths (n=13) and the DUI cases (n=208) were much lower, i.e. 0.28 and 0.22 mg/L, respectively. Amphetamine blood concentrations up to 6.0 and 2.3 mg/L were seen in the drug related deaths and DUI cases, respectively. The most frequently encountered amphetamine-based drugs in the investigated deaths were MDMA and amphetamine. The majority of MDMA- and amphetamine-caused deaths, i.e. 90% of these deaths, occurred with blood concentrations above 1.5 and 0.80 mg/L, respectively. MDMA and amphetamine blood concentrations in drug related deaths and DUI cases, however, overlap the range of fatal concentrations. Therefore, MDMA or amphetamine concentrations should never be used alone to establish the cause of death.     

Auflösung des Dienstwohnungsmietvertrages aus Anlass eines Betriebsübergangs

Bejaht man die Beendigung der überlassung der Dienstwohnung auch für den Fall der Beendigung des Arbeitsverh?ltnisses durch den Arbeitgeber, dann hat dies auch für den übergang des Arbeitsverh?ltnisses auf einen neuen Arbeitgeber infolge Betriebsübergangs zu gelten. Der neue Arbeitgeber tritt anstelle des alten Arbeitgebers in das Arbeitsverh?ltnis ein. Im Verh?ltnis zwischen Arbeitnehmer und altem Arbeitgeber kommt es – wie bei der Kündigung oder Entlassung des Arbeitnehmers durch den Arbeitgeber – zu einer Beendigung der bisherigen Beziehung. Wird das Arbeitsverh?ltnis beendet, entf?llt mangels abweichender Vereinbarung auch das Benutzungsrecht an der Dienstwohnung. Eine Aufkündigung nach der ZPO hat nicht zu erfolgen, vielmehr ist sogleich eine R?umungsklage zul?ssig.

The Effects of Dextromethorphan on Driving Performance and the Standardized Field Sobriety Test

Dextromethorphan (DXM) is abused most commonly among adolescents as a recreational drug to generate a dissociative experience. The objective of the study was to assess driving with and without DXM ingestion. The effects of one‐time maximum daily doses of DXM 120 mg versus a guaifenesin 400 mg dose were compared among 40 healthy subjects using a crossover design. Subjects’ ability to drive was assessed by their performance in a driving simulator (STISIM^® Drive driving simulator software) and by conducting a standardized field sobriety test (SFST) administered 1‐h postdrug administration. The one‐time dose of DXM 120 mg did not demonstrate driving impairment on the STISIM^® Drive driving simulator or increase SFST failures compared to guaifenesin 400 mg. Doses greater than the currently recommended maximum daily dose of 120 mg are necessary to perturb driving behavior.     

Assisted reproduction and artificial insemination and genetic manipulation in the Criminal Code of the Federal District, Mexico]

The article that one presents has for purpose outline and comment on the recent modifications to the Penal Code for the Federal District of México which establish, for the first time, crimes related to the artificial procreation and to the genetic manipulation. Also one refers to the interaction of the new legal texts with the sanitary legislation of the country. Since it will be stated in some cases they present confrontations between the penal and the sanitary reglamentation and some points related to the legality or unlawfulness of a conduct that stayed without the enough development. These lacks will complicate the application of the new rules of the Penal Code of the Federal District.
