[Inspection of deceased : Issuing a death certificate]. / Prähospitale Leichenschau : Durchführung und das Ausstellen der Todesbescheinigung.

The obligatory post-mortem examination and the issuing of a death certificate are among the more unpopular medical tasks. Nevertheless, the legislature has entrusted the medical profession with a socially important task that should be carried out carefully. The examining physician decides whether the death remains a private matter or whether an official death investigation should first shed light on the circumstances of the death. The post-mortem examination system is the only instrument for the systematic detection of homicide offences. The prerequisite for issuing a death certificate is a carefully conducted external post-mortem examination, which must be carried out in full at least when certifying a natural or unexplained cause of death. In addition, the medical information on the death certificate serves epidemiological and health policy purposes and contains important information on infection control.

Organ distribution of diclazepam, pyrazolam and 3-fluorophenmetrazine.

The organ distribution of 3-fluorophenmetrazine (3-FPM), pyrazolam, diclazepam as well as its main metabolites delorazepam, lormetazepam and lorazepam, was investigated. A solid phase extraction (SPE) and a QuEChERS (acronym for quick, easy, cheap, effective, rugged and safe) - approach were used for the extraction of the analytes from human tissues, body fluids and stomach contents. The detection was performed on a liquid chromatography-tandem mass spectrometry system (LCMS/MS). The analytes of interest were detected in all body fluids and tissues. Results showed femoral blood concentrations of 10 µg/L for 3-FPM, 28 µg/L for pyrazolam, 1 µg/L for diclazepam, 100 µg/L for delorazepam, 6 µg/L for lormetazepam, and 22 µg/L for lorazepam. Tissues (muscle, kidney and liver) and bile exhibited higher concentrations of the mentioned analytes than in blood. Additional positive findings in femoral blood were for 2-fluoroamphetamine (2-FA, approx. 89 µg/L), 2-flourometamphetamine (2-FMA, hint), methiopropamine (approx. 2.2 µg/L), amphetamine (approx. 21 µg/L) and caffeine (positive). Delorazepam showed the highest ratio of heart (C) and femoral blood (P) concentration (C/P ratio = 2.5), supported by the concentrations detected in psoas muscle (430 µg/kg) and stomach content (approx. 210 µg/L, absolute 84 µg). The C/P ratio indicates that delorazepam displays susceptibility for post-mortem redistribution (PMR), supported by the findings in muscle tissue. 3-FPM, pyrazolam, diclazepam, lorazepam and lormetazepam did apparently not exhibit any PMR. The cause of death, in conjunction with autopsy findings was concluded as a positional asphyxia promoted by poly-drug intoxication by arising from designer benzodiazepines and the presence of synthetic stimulants.
