Three alcoholics (62 years, 47 years, 83 years) died between 11 and 18 h after ingestion of ethylene glycol (EG). One person committed suicide. Observed symptoms of intoxication were seizures, respiratory depression, arrhythmias and hypotonia. All died in hospital after failed attempts at resuscitation, one person did so after an 11h dialysis treatment. EG(More)
Aim: Fatal accidents with CO-intoxication were typically observed after burnings, the use of defected stoves, heaters and the use of so-called indoor barbecues. On suicidal purpose COsource of choice is often car exhaust. Extraordinary CO-sources are presented in the following three cases due to suicidal intentions as well as accidental reasons.(More)
A 65 year old woman had collected some plant leaves, cooked them in water and ate this mash with honey. A few hours after consumption first symptoms of intoxication like sickness, stomach aches and diarrhoea appeared. Her condition deteriorated, she was admitted to hospital, became comatose and finally died due to a multiorgan failure. The plants she had(More)
This study deals with the question of whether apomorphine (CAS 314-19-2; e.g. in Ixense) and its metabolites or decomposition products interfere with the specificity of immunochemical screening tests (immunoassays) for legal and illicit drugs. It was the result of the investigations that after the therapeutic use of apomorphine no relevant false-positive(More)
The authors report on the death of two women who were married to the same man one after the other. Exhumation and toxicological investigation of the first wife, who had died 7 years before, did not produce any conclusive evidence of homicide. With regard to the circumstances of death of the second wife the husband made different statements. According to the(More)
Immunoassays are presently used worldwide for the rapid screening of drugs. Despite the fact that they are a highly valuable tool for the testing of legal and illicit drugs, there is a real risk of false-positive and false-negative findings and many pitfalls must be taken into account when these tests are used in an uncritical manner and without valid(More)
A gas chromatography-mass spectrometry (GC-MS) method is described for the screening and detection of morphine, codeine, cocaine, benzoylecgonine, methylecgonine, cocaethylene, delta-9-tetrahydrocannabinol (THC), 11-nor-9-carboxy-THC (THC-COOH), 11-hydroxy-THC (11-OH-THC), amphetamine, methamphetamine, 3,4-methylenedioxyamphetamine (MDA),(More)
Pitfalls are a permanent risk in all fields of forensic- and clinical-toxicological analysis and are not only concerned with immunoassays, although they are at present mostly discussed with regard to this subject. There are risks inherent in the field of preanalysis (e.g. the sampling, transportation, storage und treatment of the samples immediately prior(More)
