Virtopsy-postmortem multislice computed tomography (MSCT) and magnetic resonance imaging (MRI) in a fatal scuba diving incident

The body of a 44-year-old scuba diver was examined using postmortem multislice computed tomography (MSCT) and magnetic resonance imaging (MRI), and findings were verified by subsequent autopsy. The goal was to find out whether the important pathomorphological findings for the reconstruction of events and the identification of cause and manner of death could be identified using modem digital cross-sectioning techniques. The findings of a massive vital decompression with pulmonary barotrauma and lethal gas embolism were identified in the radiological images. MSCT and MRI were superior to autopsy in the demonstration of the extent and distribution of gas accumulation in intraparenchymal blood vessels of internal organs as well as in areas of the body inaccessible by standard autopsy.     

Suicide Attempts and Self-Image Among Turkish Adolescents

The objective of this paper is to report on the role of self-image as an internal factor in suicide attempts of adolescents. Three groups of adolescents, suicide attempters (n = 33), nonsuicidal psychiatric outpatients (n = 50), and normal controls (n = 50), were administered Offer Self-Image Questionnaire, Beck Depression Inventory, Symptom Check List-90-R, and a socio-demographic questionnaire. The factors discriminating suicidal adolescents from the other 2 groups were increased number of siblings, being the older children, and negativity in the familial aspect of the self-image. The self-image factor was specific for suicidal girls but not for boys. Disturbance in the development of the self-image, especially in its relationship with other family members is an important risk factor in attempted suicides by female adolescents. This brings up the importance of including the family in the treatment of suicidal adolescents. None of the factors evaluated in this study are significant in attempted suicides by males. This point needs further research.     

Morbidity and cause of death in homeless persons

The Hamburg Institute of Forensic Medicine analysed 388 deaths of homeless people between 1990 and 1998 considering demographic data, post-mortem results and autopsy findings. The manner of death was either unnatural or unascertained; the autopsy rate amounted to 43.8%. The results confirm the observation discussed in the last few years that homeless people are usually in a poor state of health. In relation to the average age of death, which is 44.5 years, the number of previous diseases is high. Unnatural causes (excluding homicides) account for a high percentage, viz. 62.6%, primarily intoxications. The most frequent natural cause of death is infection (16.8%). Women account for 8.5% of the deaths with their organ findings and causes of deaths being different from those of homeless men in terms of distribution and incidence. The data presented in this report may be helpful for the improvement of the present system of medical help in Hamburg.     

Once again: risk of injury caused by blank pistols

The nature and extent of the use of blank pistols in Hamburg (according to the Hamburg crime statistics about 300 to 400 such cases per year; 34 cases involving head and neck wounds from 1989 to 1999 were investigated at our institute; among these 8 suicides, no homicide) as well as patterns of injuries caused by close distance blank pistol shots were analysed. 7 of these cases are described in detail. The results of our studies corroborate the warning statements made by many criminological and medico-legal experts regarding the danger inherent in these allegedly harmless weapons. Blank cartridge pistols can, when shot from a close distance, cause most severe injuries involving penetration into body cavities and bodily organs (especially in the head and neck), and even perforation of the skull. Therefore, we call for a much stricter control of weapons of this kind.     

The Role of EU Internal Policies in Implementing Greenhouse Gas Mitigation Options to Achieve Kyoto Targets

This paper reviews the role of internal European Union (EU) policies and measures in implementing the target for greenhouse gas mitigation in the Kyoto Protocol. It starts with a discussion of the EU Burden Sharing Agreement, which distributes the target between Member States. This leads to a review of the appropriate level of implementation of policies, i.e. at the EU level or Member State level. There is a role for the flexible mechanisms of the Protocol, particularly emission permit trading, in complementing Member State policies at the EU level. The implementation is to be done against the background of three major factors which may have an important bearing on the policies: the probable long-term requirement of substantial reductions in greenhouse gas emissions a changing structure of energy markets, following liberalisation of the gas and electricity markets EU enlargement to include economies in transition with the potential for further substantial reductions in emissions.The paper concludes with a discussion of ancillary benefits of the policies that may be substantial and a summary of the position as regards the "unfinished business" of the Protocol to be discussed at the Conference of the Parties in the Hague in November 2000.     

Sex determination and estimation of stature from the long bones of the arm

The determination of sex and the estimation of stature from bones play an important role in identifying unknown bodies, parts of bodies or skeletal remains. In medico-legal practice statements on the probable sex of a decomposed body or part of a body are often expected even during autopsy. The present study was, therefore, restricted to few easily accessible dimensions from bones which were prepared only by mechanically removing soft tissues, tendons and ligaments. The specimens came from the Anatomical Institutes in Munich and Cologne from the years 1994-1998 including a total of 143 individuals (64 males and 79 females). The mean age was 79 years (46-108), the mean body height 161cm (134-189). The following measurements were taken: maximum humeral length (mean: 33.4cm in males; 30.7cm in females), vertical humeral head diameter (mean: 5.0cm in males, 4.4cm in females), humeral epicondylar width (mean: 6.6cm in males; 5.8cm in females), maximum ulnar length (mean: 26.5cm in males, 23.8cm in females), proximal ulnar width (mean: 3.4cm in males, 2.9cm in females), distal ulnar width (mean: 2.2cm in males; 1.8cm in females), maximum radial length (mean: 24.6cm in males; 22.0cm in females), radial head diameter (mean: 2.6cm in males, 2.2cm in females) and distal radial width (mean: 3.6cm in males; 3.2cm in females). The differences between the means in males and females were significant (P<0.0005). A discriminant analysis was carried out with good results. A percentage of 94.93% of cases were correctly classified when all measures of the radius were applied jointly, followed by humerus (93.15%) and ulna (90.58%). Applied singly, the humeral head diameter allowed the best distinction (90.41% correctly grouped cases), followed by the radial length (89.13%), the radial head diameter (88.57%) and the humeral epicondylar width (88.49%). The linear regression analysis for quantifying the correlation between the bone lengths and the stature led to unsatifactory results with large 95%-confidence intervals for the coefficients and high standard errors of estimate.     

Effects of profound hypothermia on the blood-brain barrier permeability in acute and chronically ethanol treated rats

This study examines the effects of profound hypothermia on the blood-brain barrier (BBB) permeability in ethanol administrated rats. Vascular permeability to intravenously injected Evans blue (EB) was quantitatively examined in the brain regions of rats. Rats were treated with ethanol acute and chronically. Rectal temperature of rats was dropped into 20+/-1 degrees C during profound hypothermia. Mean arterial blood pressure in both acute and chronic ethanol treatments plus hypothermia significantly dropped into low levels as well as in hypothermia alone (P<0.01). Hypothermia led to a significant increase in the content of EB dye in the brain regions of rats (P<0.05). Both acute and chronic ethanol treatments plus hypothermia did not lead to a significant increase in the BBB permeability against intravenously injected EB dye. We conclude that ethanol intake protects the BBB against the effects of hypothermia.     

Education cooperation in the European Union at the threshold of the New Millenium

The principles of ‘double relevance’ and ‘user-friendliness’ are seen as being essential for the implementation of the EU education programmes SOCRATES II and LEONARDO da VINCI II. Against the background of the acquis in EU education cooperation two points are explored: a) the articles of the Treaty are not fully used, and b) the framework set is increasingly proving to be too restrictive. The Luxemburg process and the Bologna conference are the reason for the second point. The opinion is put forward that the exchanges of students and teachers and the information exchange can be further europeanized and, eventually, be organized in permanent European structures. This revised version was published online in July 2006 with corrections to the Cover Date.     

Coexistence of public and private job agencies: Screening with heterogeneous institutions

In response to the analysis of bureaucracies and the finding of inherent inefficiencies, public choice theory argues for an increase in competition by contracting out government services and deregulation. The paper explores the effect of coexisting public and private employment services in a model with private information of the worker about her ability and unobservable effort choice. The employer's use of an efficient unemployment exchange and an efficient private agency may lead to optimal screening with first best contracts. This is due to the assumption that good types of workers lose more human capital than bad types in periods of unemployment or mismatch. In contrast to standard screening contracts, a bad type of worker earns an information rent if the employment exchange is inefficient, but the employer chooses not to use the private agency for good types.     

Lethal child abuse (through the use of physical force) in the German Democratic Republic during the period 1 January 1985 to 2 October 1990. Results of a multicenter study

No reliable data are available on cases of lethal child abuse (by active force) in the area of the former German Democratic Republic. In a multicenter study we therefore examined the police and court records for such cases occurring in the period 1 January 1985 to 2 October 1990 in the entire area of the former German Democratic Republic. RESULTS: The study center received information on 39 cases of lethal child abuse which correspond to approximately 7 cases per year. However, a low percentage of undetected crimes which cannot be determined more precisely has to be taken into consideration. Almost 40% of the victims were younger than 1 year, 73% of the victims showed indications of repeated ill-treatment. The effects caused by using direct blunt forces, against the head in particular, were by far the most frequent causes of death. The male contact person (the victim's father, brother or stepfather as well as the life companion of the child's mother in particular) killed the child in most of the cases. As far as it is known, 37% of the male/female offenders suffered from chronic alcoholism; 32% of the male/female offenders were under the influence of alcohol when the crime happened. 83% of the male/female offenders who were found guilty made a confession shortly after the crime had happened or during the interrogations. Almost all the male/female offenders were sentenced to prison (the duration of the imprisonment varied between one year and for life). Due to the considerably lower section rate compared to the one in the German Democratic Republic, it is to fear that each second fatal child abuse is not detected in the new federal states.
