Neurocysticercosis results when the ingested eggs of the pork tapeworm, Taenia solium, hatch into larval forms that penetrate the gut wall, disseminate hematogenously, and then encyst in the brain. The subsequent symptoms and associated morbidity are variable. Worldwide, cysticercosis is the most common parasitic disease affecting the central nervous system, but it is not a common autopsy finding in the United States. Neurocysticercosis may be an incidental finding, a contributing cause of death, or the underlying cause of death. It is also important for the forensic pathologist to be aware of the possibility of neurocysticercosis in the autopsy population for purposes of epidemiology studies and infection control. The authors use cases of neurocysticercosis found at autopsy at their institution to give examples of each scenario and to review the clinical and pathologic features of this parasitic disease. 相似文献

A method to reliably distinguish menstrual blood from blood in the normal circulation (peripheral blood) would be of considerable use in the forensic analysis and interpretation of evidence in sexual offence investigations. Previous attempts to address this issue have explored microscopy, lactate dehydrogenase isozyme identification, mRNA and miRNA profiling, and identification of the products of fibrinolysis. Here, four assays for D-dimer, a terminal degradation product of fibrinolysis, are evaluated for their specificity and sensitivity in detection of menstrual blood. In addition the effect of exercise, and sample storage upon D-dimer detection was investigated. Comparison of different assays revealed significant differences in results given. Nevertheless, no positive results for D-dimer were obtained using peripheral blood, mixtures of peripheral blood with semen, or peripheral blood taken from donors after moderate exercise. D-dimer was found to be detectable in 100% of menstrual blood samples after 1 week at room temperature and also in samples stored long-term (>3 years) at -20 °C. D-dimer may be an effective, simple to use tool for the presumptive identification of menstrual blood identification. 相似文献
