| Research Abstract |
Three hundred and seven forensic autopsy cases of sudden infant death were collected from 31 departments of forensic medicine in Japan and statistically analysed from the various view points, such as time of death, mode of death, ante mortem clinical symptoms, death scene investigation including sleeping position, autopsy diagnosis and autopsy findings. Of total cases 39.7% were diagnosed the cause of death as sudden infant death syndrome (SIDS) and 61.5% of SIDS cases were found dead in prone position. On the basis of these analytical results, we proposed forensic pathological criteria or minimal requirements for diagnosis of SIDS.According to the criteria, SIDS always should be diagnosed after thorough autopsy of the deceased and simultaneously complete deny of the external death, caused by murder, child abuse, accidental asphyxiation etc. When external death is suspected from death scene investigation and sleeping position, particularly prone position, we should not diagnosed SIDS.As special communications we studied on analysis of judicial precedents about sudden infant death cases, immunohistochemical analysis of transferrin and ferritin in the brain from sudden infant death cases, pulmonary neuro endocrine distribution and fatty change of the lever cells in SIDS cases.
