Germany's Constitution and participation in international peacekeeping operations

In this article, Torsten Stein, Professor of Constitutional, European and Public International Law and Director of the Institute of European Studies at the University of Saarland, Saarbrücken, traces the constitutional development that has enabled Germany to take part in a meaningful way in United Nations peacekeeping operations (PKO). As in Japan, Germany's post-war Constitution (Basic Law) was held to prohibit such participation. Germany's Federal Constitutional Court, however, has found an interpretation of the Constitution that - without amending the Constitution or any other pertinent legislation - allows a "German solution" which reconciles the putative post-war prohibitions with Germany's obligations as a member of the United Nations. Stein, who is also a Colonel in the German Air Force Reserve, warns that the "five conditions" contained in Japan's 1992 Peacekeeping Operations Law are unrealistic in view of present day PKO, but envisages an interpretation of the Japanese Constitution that might follow the German example.     

The multidisciplinary approach to dealing with families: a model for medical examiners

Medical examiners function primarily to determine cause and manner of death, and to document illness and injuries. Equally important, however, is the role of providing family members with the initial tools to work through the grief process. By initiating contact with the family, facilitating access to other appropriate services and by making provisions for adequate viewing and meeting facilities, we fulfill these ethical duties and carry out our responsibilities as physicians. We hope to fill some of the void that exists in the forensic medical literature with this presentation and generate awareness for the neglected role of grief intervention.     

A simple and cost-effective method for preparing DNA from the hard tooth tissue, and its use in polymerase chain reaction amplification of amelogenin gene segment for sex determination in an Indian population

The use of teeth as an important resource in the analysis of forensic case history by polymerase chain reaction (PCR) or other related methods has been reported. However, a major drawback in using teeth has been that the DNA is present only in trace amounts, and the methods to recover DNA from the flinty material have not been efficient or cost effective. In this report, we describe a method to prepare DNA from the hard tooth tissues. Our studies show that ultrasonication of teeth samples yields sufficient amounts of good quality DNA useful for PCR-based diagnostic methods. The teeth could serve as a reliable source of DNA for amplification-based forensic methods in sex determination. DNA could be obtained from any tooth, regardless of the age of subject. Furthermore, by using the AMEL gene-based primers in PCR, we have shown that the AMEL gene serves as a good marker for sex determination in the Indian population. In our study, the PCR-based method was sensitive and proved to be successful for sex determination with a complete specificity.     

Comparative characteristics of angulometric parameters of teeth and dentitions in terms of personal identification

Angulometric teleroentgenographic characteristics of teeth were compared for 158 subjects. A computer technology of calculation and assessment of 47 angular (quantitative) parameters characterizing spatial position of the teeth and jaws is proposed. This complex of parameters can be used as an additional test in personal identification.     

Definitions of suicidal behavior: lessons learned from the WHo/EURO multicentre Study

Based on the experience matured during the 15 years of the WHO/EURO Multicentre Study on Suicidal Behavior, this paper provides an excursus on main elements that characterize components for definitional needs. It describes the rationale for choosing the initial set of definitions within the study and the subsequent problems and developments. As a result, unifying terminologies are proposed.     

Representation of cerebral bridging veins in infants by postmortem computed tomography

The postmortem diagnosis of shaken baby syndrome, a severe form of child abuse, may be difficult, especially when no other visible signs of significant trauma are obvious. An important finding in shaken baby syndrome is subdural haemorrhage, typically originating from ruptured cerebral bridging veins. Since these are difficult to detect at autopsy, we have developed a special postmortem computed tomographic (PMCT) method to demonstrate the intracranial vein system in infants. This method is minimally invasive and can be carried out conveniently and quickly on clinical computed tomography (CT) systems. Firstly, a precontrast CT is made of the infant's head, to document the original state. Secondly, contrast fluid is injected manually via fontanel puncture into the superior sagittal sinus, followed by a repeat CT scan. This allows the depiction of even very small vessels of the deep and superficial cerebral veins, especially the bridging veins, without damaging them. Ruptures appear as extravasation of contrast medium, which helps to locate them at autopsy and examine them histologically, whenever necessary.     

Medicolegal aspects of witnessed suicide due to gunshot to the head. Part 1: Circumstances and psychopathology

In the USA the frequency of witnessed suicide, i.e. suicide committed in the presence of at least one further individual, is reported to range between 5 and 15%. As up to now no detailed analysis of this special issue has been given in the medicolegal literature, this article presents and discusses a number of cases including 8 males and 1 female (age 19-58 years, mean 41.2 years) who had all committed suicide by inflicting a gunshot to the head. In 3 cases post-mortem blood alcohol concentrations of 1.73, 1.88 and 2.23 g/kg respectively were observed. Toxicological tests produced negative results. 5 cases had a medical history of psychiatric disorder with endogenous depression in 3, chronic alcohol abuse and drug abuse with concomitant psychosis in one case each. As far as the motives were known, domestic arguments were of prevailing importance. With one exception the suicides were committed at home. In 6 cases one witness was present, in 2 cases 2 individuals and in one case 22 persons witnessed the suicide. The reported cases are discussed in comparison with the psychiatric-psychological classification according to McDowell et al. with the aim to provide a solid and comprehensive medicolegal method to distinguish between homicide and suicide. Furthermore aspects of psychiatric sequelae and psychological support of the witnesses, which are also of importance for the forensic pathologist called to the scene, are discussed.
