A single-centre review of suspected sudden infant death cases

This study aimed to establish the number of deaths in infants under 1 year of age that were being reported for medico-legal examination at a single large academic centre in Hungary, as well as the method of these investigations with special emphasis on histopathology, ancillary techniques and the adherence of our current practice to international recommendations. A single-centre, retrospective audit was conducted on all suspected sudden infant death cases. After the review there were eight infectious background sudden infant death syndrome (SIDS) cases, infectious respiratory tract disease in 14 cases, cardiac septal tumour in one case, and hepatic, possibly metabolic, disorder in one case. Our study has highlighted that even in a single institution there is a huge heterogeneity of approaches which needs standardisation. A reclassification of infant cases according to the San Diego definition resulted in a decreased number of SIDS cases in our material. The San Diego definition and related international recommendations were found to be practical and the classification provides a guide to the standardisation of current practice.
