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

A series of recent papers have shown how to formulate complex problems of forensic DNA identification inference, such as occur in disputed paternity or criminal identification cases, in terms of Probabilistic Expert Systems (PESs). However, at the present time, general purpose PES software is not particularly well suited to the repetitive tasks of: specifying an appropriate set of marker networks for a specific problem; for editing the many local conditional probability tables; and combining evidence from several genetic markers to evaluate likelihoods. Here, I describe a user-friendly prototype software tool called FINEX developed both to automate such tasks and also to evaluate likelihoods of interest. Ease of use is achieved by a graphical specification language that enables a user to quickly specify a range of forensic DNA problems. I describe the algorithms by which FINEX converts the user input in the graphical specification language and data on observed markers to the Bayesian networks used in PES. 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

The authors present the case of a man who was hospitalized after claiming that he was about to become a serial killer. The patient presented with extensive written homicidal fantasies and homicidal intentions without evidence of actual homicidal acts. In addition to routine assessments, hospital staff members used case conferences, psychological testing, outside forensic consultation, and a forensic review process to make decisions regarding diagnosis, treatment planning, and discharge. The patient was discharged after 8 months of inpatient treatment and was apparently free of homicidal impulses or symptoms of severe mental illness. A 2-year court commitment allowed for the enactment and potential enforcement of a discharge plan that was endorsed by the patient, the hospital, and community care providers. The authors review diagnostic and risk management issues. Comparisons with known features of typical serial killers are made. 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

In October and November 1940, the German Military Command which ruled conquered Belgium, introduced a series of measures aimed
at the identification and exclusion of the Jews of that country. The Belgian government of the day refused to allow the measures
to be incorporated into Belgian law, but did permit, under their reading of the Hague Convention, government departments and
local administrations to assist in implementing the German anti-Jewish Decrees. The Brussels Bar, Prosecutors and Court of
Cassation refused to accept the authority of the Occupier to violate basic rights guaranteed under the Belgian Constitution.
Officials in Antwerp, on the other hand, struck all lawyers identified as "Jews" from the Roll. This article examines these
instances of "constitutional patriotism" and "constitutional betrayal" by these actors in the Belgian legal system, and offers
some preliminary discussion of important questions about our historical and current understandings of legality, legitimacy
and citizenship in light of this part of the Belgian experience of law under Nazi occupation.
