title: Diagnostic aspects for epidemic hemorrhagic fever in legal medical autopsy: report of 2 cases and review.
abstract: Epidemic hemorrhagic fever (EHF) is known also as hemorrhagic fever with renal syndrome (HFRS). Hantaviruses, a notorious cause of EHF is spreaded by rodents or biting insects, can cause epidemic hemorrhagic fever. This report describes two rare medico-legal autopsy cases died from epidemic hemorrhagic fever. The victims were two male individuals aged 34 years and 29 years. The medico-legal autopsies were requested for alleged medical negligence. In both cases, autopsy reveals lesions to kidneys and lungs with multiple organ hemorrhage and edema, indicative of the generalized capillary damage. On admission to hospital, both patients had the symptom of fever, lumbago, renal failure and recent outdoor activities. The laboratory diagnosis results indicating multiple organ dysfunction syndrome are also important for certificating of EHF. Though the ELISA-based detection of virus-specific IgM antibody which has the highest titers between 8 and 25d after onset of disease is positive in the 34-year-old case and negative in 29-year-old case, the pathological findings and clinical laboratory analysis suggested the both victims died of EHF. In addition, immunohistochemistry analysis for Hantavirus antigen in lung or in tubular cells and PCR having been used increasingly in recent years contribute to the diagnosis of Hantavirus infection.
