Abstract

Sudden unexpected natural death (SUND) has several characteristics, such as unknown clinical history, very short course to death, evidence of trauma, interference of postmortem changes and social implications of diagnosis. From these points, SUND involves important challenges in forensic pathology. Presented here are the highlights of our SUND studies which allow scientific speculation into the antemortem pathophysiological course to death and a subsequent accurate diagnosis of the cause of death in SUND cases. 1. Forensic problems of SUND of unknown etiology 1) Do sudden infant death syndrome (SIDS) studies continue endlessly? In Japan there are many cases of sudden unexpected infant death (SUID) which were regarded as SIDS, often without postmortem examination. Pure SIDS should be a diagnosis of exclusion under thorough postmortem examination. Additionally, many SIDS studies have focused on pathogenesis of pure SIDS based on the analysis of so-called SIDS cases described above. In this sense, SIDS studies may continue forever. To clarify whether SIDS is an onion type, that is a heterogeneous disease entity, or bamboo shoot type, a single disease entity with a single cause, it is more vital to accurately search autopsy finding...Continue Reading
