A 43-year-old woman who was receiving oral antibiotics for several days for a superficial foot infection developed a persistent rash, fever, and lymphadenopathy, despite discontinuation of the antibiotic and administration of steroids for a presumed drug reaction. Hours after a subsequent visit to the emergency room for worsening symptoms, she died at home. At autopsy, there was a florid, systemic proliferation of polyclonal plasma cells and immunoblasts infiltrating nearly every organ and tissue of the body, most notably the lymph nodes and spleen. The polyclonal nature of the process was confirmed by immunofixation electrophoresis and immunohistochemistry. Cases of fatal polyclonal systemic immunoblast proliferations are extremely rare, and the trigger for such proliferations is not always known. We review the literature on this unusual entity and discuss the clinical and pathologic findings.  相似文献

The authors report the case of a 21-year-old man who was killed while duck hunting when a shotgun accidentally discharged, shooting him in the head. The loaded weapon, which had been lying on the ground with the safety off and the muzzle pointed toward a river a few feet away, discharged when a hunting dog stepped on the trigger. Scene investigation confirmed that the victim had been standing in the river, planting decoys, with his head approximately level with the adjacent bank. Autopsy examination and ballistic testing confirmed a range of fire consistent with the witness' statements. Examination of the weapon in question documented a light trigger pull but no mechanical defects. The authors review the epidemiology and causality of hunting accidents and discuss the various safety rules that were violated in this highly unusual case. The importance of a complete death investigation, including autopsy, when dealing with a firearm death is emphasized.  相似文献

This study examines the association of self-perceptions with sixth to eighth graders' exposure to mixed-sex and dating contexts. It contrasts two hypotheses: the stress hypothesis, which suggests that the transition to romantic relationships will be associated with declines in self-esteem, especially for girls, and the leisure hypothesis, which suggests that movement into a desired role in an emotionally positive social context will be associated with positive emotions and higher self-esteem. Results indicate that adolescents experience mixed-sex settings positively, and that comfort with the other sex (for girls) and more time spent with the other sex (for boys) are predictive of more positive self-perceptions. Activity diary data suggest that these differences are due to differences in the emotional climate of same- and mixed-sex settings, rather than to the activities adolescents engage in with same- and mixed-sex groups. Dating boys who are less interested in dating experience lower self-esteem. Results are discussed in light of the transitional nature of mixed-sex relationships in early adolescence and the preparatory role played by same-sex friendships.  相似文献

A validation study was conducted to demonstrate that deoxyribonucleic acid (DNA) could be successfully extracted from human nail material and analyzed using short tandem repeat (STR) profiling and/or mitochondrial DNA (mtDNA) sequencing. This study involved the development of a DNA extraction protocol that includes a cleaning procedure designed to remove external contaminants (e.g., biological, chemical). This protocol was used to test human nail material that had been soaked in whole blood from a second donor and coated with gold-palladium to simulate scanning electron microscopic analysis. The results showed no indication of a mixture and were consistent with that of the nail donor. Fresh human nail material usually yielded both STR profiles and mtDNA sequence information; however, aged human nail material (approximately eight years old) yielded only mtDNA sequence information. Upon completion of the validation study, the extraction protocol was used for the analysis of a torn fingernail fragment recovered from the scene of a violent homicide in 1983. A partial STR profile and mtDNA sequence information indicated that the fingernail fragment was excluded as originating from the suspect and was, in fact, consistent with originating from one of the victims.  相似文献

This article interprets Joon-ho Bong’s Snowpiercer (2013) as a political allegory. First, we compare Bong’s film to Danny Boyle’s Sunshine (2007) and Christopher Nolan’s Interstellar (2014), two contemporaneous films about ecological crises. We argue that Snowpiercer exposes the limits of technocratic environmentalisms that obscure the links between ecological degradation, capitalist development, and colonial domination. Second, we put Bong’s film into conversation with autonomist Marxist and postcolonial accounts of social domination and transformation. We argue that Snowpiercer is about whether or not contemporary political economy has rendered the emancipatory strategies of recent centuries obsolete. Framed this way, the film proposes that global order is still capitalist and colonialist, but that Left projects must surpass state socialism and anti-colonial nationalism. What we call Bong’s “decolonial exodus” is the demand for a real alternative to both the ideology that there is no alternative to the existing order and the pseudo-alternative of authoritarian populism.  相似文献

Many law enforcement agencies are currently responding to the problem of online crime by establishing proactive investigative units that track criminals on the Internet. Not only do these specialized teams face problems in the area of emerging technology, they are also faced with handling emerging legal issues. The current research examined the issue of the entrapment defense, and how previously established physical realm doctrine could be applied to the investigation of online crimes such as child pornography. Relying on previous case law it would appear that entrapment claims related to online sting operations involve consideration of: a) did the law enforcement officer continuously contact the suspect with the intention of trying to convince the individual to engage in a particular type of behavior, b) how long was the relationship between the undercover officer and the suspect, and c) how much, if any, reluctance to commit the criminal act did the suspect provide evidence of?  相似文献

中国和朝鲜关系自1999年开始恢复,这虽不表示两国已恢复过去的同盟关系,但一定会对朝今后的发展起到积极作用.本文首先介绍中朝关系的变化;然后分析在向朝鲜提供改革模式及理念、经济资源、政治军事援助过程中,中国对朝鲜变化产生的影响;最后得出主要结论,即虽自20世纪90年代后期开始,朝中关系正式进入恢复阶段,但双方关系不再以共享理念和战略目标为基础,而是基于现实利益或战术目标.朝中关系这一新特点将继续制约中国对朝鲜变化过程的影响.此外,文章还针对朝鲜的发展变化,就中韩合作问题提出了若干建议.  相似文献
