The international medical literature described sporadical cases of an exceptional event called the "Lazarus phenomenon". This is the spontaneous reviviscence of an individual after a long time of asystolia following a cardiac accident depending on different pathogenesis (i.e. arrhythmia, ischaemic stroke, haemorrhage, brainstem death). ⋯ We report the case of an 81-year-old woman who experienced a cardiac accident on the street. Once the cardiopulmonary resuscitation was interrupted, the patient presented life activities after some minutes.

A zero-concentration limit for controlled scheduled drugs in the blood of motorists was introduced in Sweden in 1999 and the annual number of arrests for driving under the influence of drugs (DUID) has since increased eight-fold. However, for prescription drugs that might cause impairment (e.g. benzodiazepines) additional proof is needed to justify prosecution, such as whether the medication was being misused. Over a 2-year period, we found 94 cases of DUID in which the concentrations of diazepam in blood was 1.1 microg/g or more. ⋯ Other psychoactive prescription drugs were identified in blood including alprazolam, flunitrazepam, oxazepam, zolpidem and zopiclone. This case series of DUID suspects demonstrate the high frequency of polydrug use showing preference for illicit drugs like amphetamine, cannabis and heroin, in that order. Furthermore, Swedish traffic delinquents frequently overdose with prescription drugs as exemplified here by unusually high concentrations of D and its active metabolite ND.

Delta9-Tetrahydrocannabinol (THC) and 11-nor-Delta9-tetrahydrocannabinol-9-carboxylic acid (THCA) are equally used to indicate consumption of cannabis (hashish and marijuana). Publications of the early 90's demonstrate the possibilities of determining THC, cannabinol (CBN), and cannabidiol (CBD). All these substances are present in cannabis smoke and can be incorporated into the hair only by contamination. ⋯ Thirteen were negative for THC and positive for THCA, and six were positive for THC but negative for THCA. The cases were selected by an ELISA test or re-examined when the blood/urine results or the statement of the accused did not match with a THC outcome. The most appropriate strategy to prove cannabis consumption is immunochemical initial test followed by a GC/MS/MS confirmation of THCA.

Forensic medicine in the German Democratic Republic.
Forensic medicine services were resumed in the territory of the Soviet occupation zone in early summer 1945. One coherent legal system was established, following the foundation of the German Democratic Republic (GDR), 7 October 1949. ⋯ The Gesellschaft für Gerichtliche Medizin der DDR (GDR Society of Forensic Medicine) was established in 1967 and began to organise with high continuity a wide-ranging variety of scientific events. Almost all administrative districts had their own institute of forensic medicine by 1990.
