The post-mortem findings of 4 sport divers involved in accidents showed air embolism of the heart as well as 2 subcutaneous emphysemas of shoulder and neck. The lungs were distended and the viscera were hyperaemic. The pleura showed petechiae and small patchy hemorrhages. In microscopic examination foci of alveolar hemorrhages of the lungs and, occasionally, muscosal rupture of small branches of the bronchial tree and of the bronchioli could be determined. The most likely causes for the accidents are discussed and special attention is given to panicking under water.  相似文献

In the last few years, male circumcision has become the subject of controversial discussion. On the one hand, medical and hygienic arguments, ideology, freedom of religion, cultural identity and social adequacy are claimed by those supporting male circumcision. On the other hand, the justification of this practice also has to be critically scrutinized just as the question whether the parents have the right to consent to the operation. Today, opinions range from those who claim that religion and culture alone justify the practice to those who consider circumcision of minors unable to give their consent as bodily injury subject to punishment. In contrast to female genital mutilation, most positions do not postulate that circumcision violates morality. If the person concerned is able to give his consent, freedom of religion may also justify circumcision after weighing its pros and cons as well as its risks and potential side effects.  相似文献

The aim of the present epidemiological study was to investigate characteristics of assaults in the elderly aged 65 years and above from the perspective of the victim and perpetrator. This population-based study included 23,142 assaults (according to §§ 224/226 StGB of German criminal law) that were recorded in Bavaria, Germany, from 1999 to 2005. The population-based ratio of serious crimes of battery for the elderly in comparison with the reference population was markedly lower (0.10; 95% CI: 0.09-0.11) in suspects aged more than 65 years and 0.08 (95% CI: 0.07-0.09) for the injured above 65 years. Elderly perpetrators differed significantly concerning the manner of the assault (p < 0.001). They committed less crimes in urban areas (56.1% vs. 68.8%) and were victimized significantly more in rural areas (p < 0.001; 41.2% vs. 30.2%). Violence in the elderly differs from that of the younger population. Further research is warranted to establish prevention measures.  相似文献

Abstract: With sexual assault evidence, the visualization of spermatozoa confirms that ejaculation has occurred. However, microscopic examination of spermatozoa is a laborious process and can sometimes result in sperm cells being overlooked. Here, we present the developmental validation of the SPERM HY‐LITER? kit, which contains a human sperm–specific mouse monoclonal antibody coupled to a fluorescent Alexa 488 dye. The kit was tested using samples of human semen, saliva, blood, and urine, various animal semen extracts, sexual lubricants, and a commercially available spermicidal film. Postcoital vaginal swabs, degraded semen samples, and samples prepared with sample fixation techniques that deviated from the kit‐provided protocol were also tested. In each case, the SPERM HY‐LITER? kit was demonstrated to bind only to human sperm cell heads. Limitations to this fluorescent staining procedure include nonspecific staining and increased background fluorescence with extreme heat fixation in some samples.  相似文献
