Abstract:Purposes: Sudden Infant Death Syndrome (SIDS) has been reported to be the leading cause of death in infants under one year of age in many countries. Unfortunately, a paucity of published research data exists in South Africa, with regard to the incidence of and investigation into the circumstances surrounding Sudden Unexplained Deaths in Infants (SUDI) and/or SIDS. Currently, even though most academic centers conform to a protocol consistent with internationally accepted standards, there exists no nationally accepted infant death investigation protocol in South Africa. It is the aim of this study to review the current practice of infant death investigation in two representative but geographically and demographically distinct centers. Methods:Retrospective case audit over a five-year period (2000 to 2004) was conducted at two large medico-legal mortuaries in Pretoria (Gauteng) and Tygerberg (Cape Town). Case files on all infants younger than one year of age were reviewed. The outcome measures included number of deaths, demographic details and the nature and final outcome of the post mortem examinations.Results: A total of 512 cases were identified as possible SIDS cases and of these, 171 was classified as SIDS. The study showed marked inter-case and inter-divisional variation in terms of the investigation of infant deaths at the two institutions. Conclusions:It is envisaged that this study will focus attention on the current lack of usable data regarding sudden/unexplained/unexpected infant deaths in South Africa, and aid in the formulation and implementation of a practical (yet internationally accountable) infant death investigation protocol, which could facilitate comparisons with other countries and initiate further structured research in this field.

Left ventricular noncompaction has been classified as a primary cardiomyopathy with a genetic origin. This condition is morphologically characterized by a thickened, two-layered myocardium with numerous prominent trabeculations and deep, intertrabecular recesses. Recently, it has become clear that these pathological characteristics extend across a continuum with left ventricular hypertrabeculation at one end of the spectrum.The histological findings include areas of interstitial fibrosis.We present a case of left ventricular hypertrabeculation which presented as sudden infant death syndrome. Histologically areas of subendocardial fibrosis was prominent and we propose that this entity may be a hidden cause of arrhythmic death in some infants presenting as sudden infant death syndrome., with areas of subendocardial fibrosis as possible arrhythmogenic foci.

This study aimed to establish the incidence of homicide, associated pathology of trauma and victim profiles in cases admitted to or managed as homicidal deaths at the Pretoria Medico-Legal Laboratory (PMLL) over the period of [2007][2008]. A total of 1088 cases were reviewed. Homicides accounted for 22.7% of all cases admitted to the PMLL. The majority of homicide victims were male individuals (87.0%). The most common cause of death was gunshot wounds (42.6%), followed by blunt force trauma (25.1%). Homicides are most likely to occur at the victim's place of residence (28.5%) and only 37.4% of victims survive long enough to receive hospital care. The results of this study seem to concur with international findings for the most part, with a few interesting deviations. Highlighting atrisk groups, as well as dangerous locations and incident times, creates the potential to decrease the occurrence of unnecessary deaths by generating an awareness of the trends.
