The introduction of a standardized paternity index (PI) for the statistical evaluation of blood group findings in cases of disputed paternity is proposed and explained. By using the PI XY as parameter, it is not necessary to give the information of the probability of paternity in percent. The PI includes the full information of the blood group findings. In addition to that, by using the suggested standardization based on the probabilities of error according to Schulte Mönting and Walter the test volume is also taken into account. The interpretation of the mathematical result is given by verbal predicates, the limitations of which are orientated by the verbal predicates for the probabilities of error according to Schulte Mönting and Walter, published by us elsewhere. Besides the essential fact that the test volume is taken into account, the most important advantage of this procedure is that the mathematical result is involved in the court decision only by the PI (which is free of any valuation) and its verbal predicate and not by sometimes relatively high percentages, which may be misunderstood by laymen.  相似文献

Information on the diagnostic significance of follicular hemorrhage and/or presence of red blood cells in the lymph node sinus was obtained by microscopic investigation of the superficial and deep human cervical lymph nodes. Fifty cases were selected on the basis of the following criteria: (1) cases without strangulation or mechanical head trauma; (2) cases in which death occurred by strangulation without additional mechanical head trauma; (3) cases without strangulation but with mechanical head trauma; (4) cases with strangulation and mechanical head trauma. The usual degree of stasis and hemorrhages and the dilation of the veins and/or capillaries are not sufficient to discriminate between cases with and cases without strangulation. Moreover, erythrocytes, erythrophages, and siderophages were encountered in the lymph node sinus of both cases with and cases without mechanical head trauma. Neither follicular hemorrhage nor the presence of red blood cells in the sinus is therefore diagnostically significant in forensic pathology.  相似文献

As part of a transcultural investigation of violent behavior in Denmark and South America, the lesions from accidents involving deliberate violence registered in three Danish emergency wards during a 1-year period were studied. A quantity of 2211 lesions were diagnosed in 1316 patients (953 male and 363 female patients). Sixty-five percent of the lesions were in the head/neck region, 13% in truncus, 18% in the upper extremities and 5% in the lower extremities. The most frequent diagnosis was an open wound in the head/neck region. Adding contusions and fractures in the same region this amounted to more than half of the total number of lesions. In the upper extremities 62% of the lesions were contusions or open wounds. Serious lesions of internal arteries were few, however always caused by sharp instruments (knives). Serious lesions due to firearms were not recorded/reported. Strangulation had been used against 1.1% of the victims, the male/female ratio being 1:6. The main part of the lesions were of minor severity when assessed on the basis of the scores in the Abbreviated Injury Scale (AIS). The lesions were, however, more serious compared to other recent studies, and it appeared that the female victims had fewer but more serious lesions than the male victims. The need for treatment and hospitalization was in the range of other recent studies.  相似文献

Method of chrome detection in the course of forensic chemical investigation in the cadaveric material on the basis of cyclohexan-carbonic acid use is presented. Results of experimental researches showed efficacy of method tested as compared to the common one. Method suggested can be used in laboratory conditions to extract chrome from visceral organs of human cadaver.  相似文献

As part of an European-South American study of deliberate violence cases of violence against women greater than or equal to 15 years of age and violence against and among children under the age of 15 years were registered at 3 Danish emergency wards and at the Institute of Forensic Medicine in Copenhagen. 352 cases of violence against women and 46 cases of violence against children were registered in the three emergency wards corresponding to rates of about 1.6/1000 per year for women, 0.6/1000 per year for boys and 0.7/1000 per year for girls in a provincial/rural district, the catchment region of Holbaek County Hospital, 3.4/1000 per year for women, 2.8/1000 per year for boys and 0.6/1000 per year for girls in a mainly middle income area of the metropolis Copenhagen, the catchment region of Frederiksberg Hospital, and 4.0/1000 per year for women, 4.0/1000 per year for boys and 0.9/1000 per year for girls in a mainly low income area of Copenhagen, the catchment region of the Rigshospital. Nineteen live adult female victims and 17 dead adult female victims of violence were registered in the Institute of Forensic Medicine in Copenhagen, where also one was registered as a victim of homicide. Nearly half of the adult live female victims of violence had been injured at home while this was the case for approximately three fourth of the dead victims. In 35% of the live cases the husband was the aggressor and in 12% a former cohabitant. In 71% of the homicide cases the husband was the aggressor. The live women appeared to have fewer but more serious lesions than men. The pattern of deliberate violence against women appears to be associated with socio-economic and cultural factors. In cases with a preceding quarrel there is statistically a link to alcohol intoxication. In half of the cases of violence against children the aggressor was known to the victim, in 15% the aggressor was one of the parents, while 42% of the cases were violence among children. The pattern of violence according to sex, and the distribution and severity of lesions for 10-14 years old children showed resemblance to the situation for adults. The lesions were more serious in young infant victims, especially boys, than in adult victims.  相似文献
