Munchausen syndrome by proxy (MSBP) is a special form of child abuse in which an adult repeatedly produces symptoms of illness in a person under his/her care. In most cases the perpetrators are mothers who repeatedly and in different ways produce or feign symptoms of illness in their children in order to obtain medical treatment for them. MSBP is thus a special form of child abuse that is also of importance in the field of forensic medicine and a particular challenge to the medicolegal expert. We report two cases of poisoning with different substances (clozapine and clonidine) detected by toxicological investigations at our Department of Legal Medicine. The relevance of the problem for the medicolegal expert and the importance of an interdisciplinary co-operation are pointed out. 相似文献

Third molar root development in relation to chronological age: a large sample sized retrospective study 总被引:2,自引:0,他引:2
The aim of the present investigation, which is a continuation and extension of a previous published pilot study [Forensic Sci. Int. 129 (2002) 110], was to calculate the chronological age of an individual based on the dental developmental stages of third molars (so-called wisdom teeth). The evaluated material consisted of 2513 orthopantomograms (OPG's) of patients all of Belgian Caucasian origin between 15.7 and 23.3 years. The sample of OPG's was scored by two observers who were calibrated for intra- and interobserver reliability by means of kappa statistics. The kappa statistics revealed a strong agreement between the intra- and interobserver measurements. Further statistical analysis was performed in order to obtain multiple regression formulae for dental age calculation with the chronological age as the independent variable and the third molar developmental stages as dependent variables. Both for males and females a significant Pearson correlation coefficient was noticed for contralateral third molars, a smaller less significant one for the antimeres. For the application of the regression formulae one has to take into consideration the gender, the location and number of wisdom teeth. Probabilities for an individual to be older than 18 years were also calculated in case of fully developed wisdom teeth. 相似文献

According to the Turkish Penal Code, Section 456, an assailant is punished in a correlation to the severity of the victim's injury. In this study, the injury scale used in Turkey in the basis code 456 is compared with Abbreviated Injury Scale (AIS). For this aim, a total of 984 cases out of the total amount reported at the Traumatology Section of the Turkish Council for Forensic Medicine were randomly selected and evaluated retrospectively. In all, 40.7% of injuries were caused by blunt trauma, whereas 59.3% were caused by a penetrating trauma. According to the Turkish Injury Scale (TIS), 40.3% of the cases were scored to be of a first degree of injury, 15.6% as second degree and 44.1% as third degree. When compared, the score points 3, 4 and 5 in the AIS were seen to be nearly equivalent to the TIS of third degree. From this point of view, in the modified AIS 91.1% of first degree of injury, 51.2% of second degree and 97.2% of third degree of injury are harmonious with TIS. Generally, 83.2% of the cases are harmonious with the AIS system. The purpose of this study is to determine what was the source of differences and to focus on particular traumatic lesions in order to determine a possible rearrangement of the Turkish Injury Scale. 相似文献

A 30-year-old male died in Thailand after a scuffle. The corpse was embalmed and repatriated to France where an autopsy was performed. As usual in cases of embalmment, fluids such as blood and urine were unavailable and the toxicological analyses was performed on the bile and the liver. An overdose of heroin was determined as the cause of death. A review of the literature indicates that several drugs can be detected in fluids and tissues that contain formaldehyde. This case demonstrates that in embalmed corpses, toxicological assessment is still possible, e.g. after heroin fatalities. 相似文献

This article discusses the medico-scientific and the legal views of cancer causation and how these two approaches impact on expert evidence. Cancer cause lends itself well to an exploration of the critical issues which surround its proof and the role of expert evidence in this proof. The article does not seek to identify or to resolve all the controversies or inconsistencies in the area. Rather, it sets up a basic framework for the general presentation and testing of expert medico-scientific evidence in litigation related to cancer causation. Specifically, it seeks to identify the technical questions of law and medical science regarding which medico-scientific disciplines can be relevant to proving cancer causation, and who the relevant expert witnesses to achieve this task would be. Emerging areas of cancer causation are then examined in light of this framework. 相似文献
