title: Death during immersion in water in childhood.
abstract: Drowning is a relatively common cause of accidental death in children. Autopsy records at the Adelaide Children's Hospital over a 27-year period from 1964 to 1990 were examined, and 58 cases were found where the cause of death was listed as drowning. In six cases, however, careful examination of the history and postmortem findings provided important additional information that suggested a more complex antemortem sequence of events. Specifically, four patients aged between 6 years, 10 months and 11 years were known to have had epilepsy. A further patient, an 8-year-old boy, died from a subarachnoid hemorrhage due to a bleeding cerebral arteriovenous malformation while swimming. The final patient, an 11-year-old boy who collapsed in a public swimming pool, was found at autopsy to have marked hypoplasia of the right coronary artery. In this series, six of 58 (10.3%) of the pediatric cases had additional underlying medical problems that could either have initiated the drowning episode or caused death due to alternate mechanisms. We present the clinicopathological findings in detail to demonstrate that a high index of suspicion must be maintained in all cases of pediatric drowning, not only for unnatural causes of death but also for additional natural disease processes that may have contributed significantly to the fatal episode. These findings may have particular relevance in jurisdictions where full postmortem examination is not always required by law.
