The significance of the legal term "corpse" in forensic medicine

The definition of the term "corpse" is relevant for medicine in general and most particularly so for forensic medicine, as it has direct consequences on practical work: legally, postmortems and autopsies may only be performed on corpses. With this in mind, the legal term "corpse" was examined on the basis of German State Law regulations and provisions. Approximately half the burial acts include a definition of "corpse", but even here there are certain variations. The definitions for "corpse" can be divided into four categories: 1) according to the lack of vital signs or sure signs of death 2) according to the degree of decomposition and/or cohesion of body parts 3) on the basis of severed body parts, and 4) terminological differentiation of stillbirths and neonatal fatalities from miscarriages. Laws vary greatly in their definition of the term "corpse". Therefore, the decision whether or not human remains or parts thereof qualify as a "corpse" should be left to medical discretion.     

Reliability of % vol. declarations on labels of wine bottles

The Council Regulation (EC) no. 1493/1999 of 17 May 1999 on the common organisation of the market in wine (Abl. L 179 dated 14/7/1999) and the GMO Wine 2000 (Annex VII A) stipulates that the labels of wine bottles have to indicate, among others, information on the sales designation of the product, the nominal volume and the alcoholic strength. The latter must not differ by more than 0.5% vol. from the alcoholic strength as established by analysis. Only when quality wines are stored in bottles for more than three years, the accepted tolerance limits are +/- 0.8% vol. The presented investigation results show that deviations have to be taken into account which may be highly relevant for forensic practice.     

Determination of cathinone,cathine and norephedrine in hair of Yemenite khat chewers

A sensitive and reproducible method for the quantitative determination of cathinone (CTN), norpseudoephedrine (NPE, cathine) and norephedrine (NE) from hair was developed. The compounds were extracted for 4 hours with phosphate buffer pH 2.0, followed by a standard solid phase extraction procedure on a mixed phase column, derivatization with heptafluorobutyric anhydride (HFBA) and GC-MS separation and quantification using D(3)-ephedrine (D(3)-E) and alpha-aminoacetophenone (AAP) as the internal standards. The diastereomers NPE and NE were satisfactorily separated. In the validation, the limits of detection and of quantification were determined at 0.03-0.08 ng/mg and 0.10-0.24 ng/mg, respectively and the interday standard deviation was between 10 and 15%. The method was applied to hair samples of 24 Yemenite khat chewers. All three compounds were detected in 23 of these cases. The concentrations ranged from 0.57 to 23.9 ng/mg for NPE, 0.19-25.0 ng/mg for NE and 0.11-22.7ng/mg for CTN. A highly significant correlation was found between the self-reported data about the khat consumption habits of the volunteers (4-56h chewing per week) and the concentrations of norephedrine and norpseudoephedrine in hair.     

Building a ‘culture of dialogue’ among stakeholders in North-West Russian oil extraction

This article analyses the development of relations between indigenous communities, oil companies and the state in Russia's Nenets Autonomous Okrug (NAO). Using first hand information from anthropological fieldwork and one co-author's own involvement in regional politics, we analyse efforts to establish stakeholder dialogue. We show that ‘collective agency’ is crucial to prepare the ground for trustful relations, whereas high personnel turnover within interest groups jeopardises initially promising initiatives. Lessons from this experience have relevance for similar analyses throughout Russia in those cases where consistent federal and regional legislation is not likely to be in place in the near future.     

Forensic medicine aspects of fatal coronary insufficiency with normal coronary arteries

Clinical experiences give examples for the existence of various courses of anginal symptomatology even with cases of sudden heart death demonstrating angiographically normal coronary arteries. Pathogenetically may be considered spasms of regular or little changed coronary arteries, coronary muscle bridges and acute arrhythmias. In cases of recurrent myocardial ischemias an interstitial fibrosis and endocardial fibrosis can be proved histologically in the myocardial supply area. However an acute coronary insufficiency based on rheological and metabolic etiology cannot be found with morphological methods. The results are discussed, considering forensic aspects in cases of competitive causes of death.     

Acute and subacute fetal CO-poisoning

The main principles of placental CO exchange in cases of CO intoxications of pregnant women are shown. Fetal COHb lags behind maternal COHb by several hours depending on the exposure pattern. During CO elimination the fetal COHb levels again lag behind the mother's. A case of a lethal CO intoxication of a pregnant woman, mens IX, with exposure time of 10-12 h and COHb of 75% for the mother and 46% for the fetus allows to make conclusions about process of intoxication and about different times of death for mother and fetus. In highly acute lethal intoxications of the mother COHb in fetal blood is low or negative. A vital danger of the fetus is not probable when mother survived a short CO exposure.     

Screening and detection of amphetamine derivatives in biological stains

A GC/MS-method is described for the screening, detection and determination of the commonly used drugs amphetamine, methamphetamine, MDA, MDMA and MBDB in small blood samples and bloodstains using solid phase SPE columns and a pipetting robot (Gilson Aspec XL). The detection limits are in the order of 0.03 to 0.08 microgram/L and the correlation factors between 0.9982 and 0.9998. Furthermore the stability was investigated covering a storage time of 64 days. The method has proven useful in forensic cases with only small sample volumes or bloodstains.     

Cadaver mix-up--an avoidable problem?

Depending on local conditions it may happen from time to time that no officer involved in the previous investigation is present during the forensic autopsy. In this case, the post mortem examiner often has to rely solely on written documentation concerning the identity of the deceased. The authors report a case where the body had already been mixed up with another body by the undertaker prior to the inspection by the police. In spite of clear distinguishing characteristics in the written documentation, this led to the wrong body being autopsied. For the post mortem examiner, the only safe way to identify a body seems to be the presence of persons who had known the deceased or of police officers as acknowledging witnesses. If these conditions are not given, other means of safe information on the identity are called for, for example a "police body card" similar to an evidence card.
