A case of the sudden death of a 14-month-old girl due to massive hemorrhage in a primitive neuroectodermal tumor (PNET) is presented along with a review of the relevant literature. PNET is a rare, malignant brain neoplasm occurring predominantly in children.  相似文献

Although a devout Evangelical, living in an era that largely predated the dissemination of sexological discourses of female same-sex desire, Constance Maynard (1849–1935), the prominent Victorian educational reformer, pursued a series of same-sex relationships. This essay focuses on Maynard's relationship with the Anglo-Irish Marion Wakefield (1876–1956), exploring the role of Maynard's erotic imagination in the constitution, contestation, and consolidation of the imagined geographies of imperialist discourse. Maynard's erotic positioning of her lover in diverse imperial landscapes reveals the ostensibly ‘private’ discourses of the erotic imagination to be profoundly implicated in the ‘public’ discourses of empire. At the same time, the domestic settings in which these landscapes were imagined and in which the women's illicit desires were enacted, pose a challenge to the gendered spatial dichotomies—private/public, domestic/imperial, and home/away—of both imperialist discourse and the historiography of empire.  相似文献

International and national level disability inclusive discourse, policy and strategy typically render invisible the institutional structures, political economies and socio-cultural power relations that constitute the lived experience of disability. The lack of robust information on disability extends these theoretical blind spots to the absence of disability in official statistics, political dialogue and social policy. Empirically grounded, inclusive research that recognises disability as embedded in globalised political economies and culturally specific power relations is required to address the theoretical, statistical and programmatic invisibility of disability. Such research will provide a solid knowledge base on which to build effective inclusive interventions.  相似文献

A 55-year-old man complained of sudden onset of severe neck pain. This was followed by prompt loss of consciousness and death. Autopsy revealed rupture of a saccular aneurysm, which was considered to have resulted from enlargement of the remaining ductal tissue, and was located on the medial aspect of the uppermost portion of the descending aorta. Dense blood extravasation was noted in the posterior mediastinum and extending to the strap muscles of the neck and larynx. Histological examination of the rupture site revealed disappearance of the medial elastic fibers and thickened intima covered with dense fibrous tissue. Spontaneous ductus arteriosus aneurysm in adults is a rare finding, but widespread use of imaging technologies has revealed that it develops more frequently than previously recognized. Fatal complications may occur even when the aneurysm is relatively small. Therefore, pathologists should be aware of this aneurysm as a potential cause of sudden death.  相似文献

An improved method for detecting diatom in blood is reported. Blood of cadavers was obtained by cardiac puncture at inquest or from the left atrium directly at autopsy. The blood was hemolyzed by sodium dodecyl sulfate (SDS) and filtered through membrane filter (47 mm in diameter and 5 microns in pore size). When the blood was putrefied, two or three pieces of membranes filters were needed because of choking membrane pore. The membrane filters were digested with fuming nitric acid and diluted with distilled water. The diluted solution was filtered through membrane filter (25 mm in diameter) again. After drying the membrane filter was immersed in oil. Diatoms on the membrane filter were clearly observed microscopically.  相似文献
