The conducting tissue of the heart was studied in a group of 38 cases of the sudden infant death syndrome and in a control group of 28 children dying of known causes. A variable amount of fibrous tissue was found in the atrioventricular complex in almost every case. There was a statistically significant increase in fibrous tissue with age in both groups(More)
DNA was extracted from human and non-primate dried blood stains. Human male and female specimens were readily distinguished by analysis with a Y-chromosome specific DNA probe. Human and non-primate blood stains were also readily differentiated using a repeat sequence (Alu) DNA probe. The potential power of recombinant DNA analysis in forensic science is(More)
In a group of 50 sudden unexpected infant deaths serial sectioning of the hearts has revealed in 11 cases the presence of petechial haemorrhages in the region of the sinus node and internodal conducting tissue tracts. It is suggested that these findings indicate myocardial hypoxia and that such disturbance of the conducting system may well account for a(More)
The pulmonary arterioles and small arteries were studied and their musculature and its nuclei were quantified in 90 neonates, infants, and young children who had suffered from a variety of clinical and hypoxic conditions immediately before death. Among the 90 cases investigated in this study, 30 were of sudden infant death syndrome (SIDS). No evidence was(More)
The histological appearance of lungs of children whose death had been sudden and unexpected has been studied in relation with the viruses found at necropsy. Fifty-one children were investigated and in 33 the lungs had the histological appearance widely accepted as characteristic of the condition previously termed "cot death." Sixteen had the histological(More)
Sera from 207 forensic autopsy cases were tested for the presence of antibody to the human immunodeficiency virus (HIV) using a recombinant immunoblot assay (RIBA) technique developed by Chiron Corporation of Emeryville, California--the Chiron RIBA-HIV216 test system. Out of these cases, 172 autopsies were of individuals with no known risk factors for HIV(More)
Respiratory viruses have been identified at necropsy in the lungs of 13 out of 24 children who died with observed acute respiratory illness. The histological appearances of the lungs supported the association between virus and death in each of these 13 children and suggested an unidentified virus aetiology in a further five cases. Histological appearances(More)
