Abstract
The autoptic procedures in sudden infant death syndrome (SIDS) and sudden intrauterine unexpected death (SIUD) victims requires an in-depth examination of the autonomic nervous system, central and peripheral, as well as of the cardiac conduction system. In these pathologies, our studies have identified frequent developmental abnormalities in the brain stem, particularly hypoplasia of the arcuate nucleus, and accessory atrioventricular pathways in the cardiac conduction system. The law 'Post-mortem Investigation on the SIDS and of Unexplained Late Fetal Death' designated the Institute of Pathology of Milan University as the National Reference Center. The objectives of this law include, in article 4, widespread informative and preventive campaigns and continuous formation of programs for medical personnel.
