Comparative Study
Comparison of volume and attenuation of the spleen between postmortem and antemortem computed tomography.
The purpose of this study is to compare the postmortem changes in computed tomography (CT) findings between normal spleen, splenic infarct, and splenic tumor infiltration. ⋯ Spleen volume decreased and attenuation increased on postmortem CT compared with antemortem CT in subjects with a normal spleen, splenic infarct, or splenic tumor infiltration. These results should caution us against underestimating the significance of splenomegaly on postmortem CT, misinterpreting reduced splenic volume as the presence of hypovolemic or distributive shock in the subject while alive, and confusing postmortem splenic hyperattenuation with diseases characterized by this finding.

Coronary artery injury is a rare complication following blunt chest trauma (BCT), and can be fatal. Here we report findings on postmortem selective coronary angiography of right coronary artery rupture after an assault involving blunt trauma to the chest. A woman in her 60s died after her son stomped on her chest. ⋯ The key points in the present case are that no fatal injuries could be determined on external examination, and the heart and coronary artery injuries were not evident on PMCT. Criminality might be overlooked in such cases, as external investigation at the crime scene would be inadequate and could result in a facile diagnosis of cause of death. This is the first report of coronary artery rupture with dissection that was detected by CT coronary angiography, and provides helpful findings for reaching an appropriate decision both forensically and clinically.

Post-mortem computed tomography (PMCT) and post-mortem computed tomography angiography (PMCTA) are rapidly becoming effective and practical methods in forensic medicine. In this article, we introduce a PMCTA approach by cardiac puncture and its application in a specific forensic case. A 50-year-old female sanitation worker was found dead on a road. ⋯ Sternal fracture and rib fractures were detected by PMCT and aortic rupture by PMCTA. The cause of death was hemorrhagic shock due to traumatic aortic rupture. In certain circumstances, the combination of PMCT and PMCTA is helpful for forensic pathologists to determine the cause of death in cases involving traumatic vascular injury.

There is a dearth of literature on the extent of fetal or newborn abandonment or "dumping" and the medico-legal investigation procedures these cases require. This is despite the fact that these occurrences are a worldwide phenomenon and by definition involve criminal law concerns such as illegal abortion, concealment of birth, murder, or neonaticide, depending on the country concerned. This article contributes to current literature in both respects and provides a retrospective case audit for the period 2004-2008 pertaining to all abandoned newborns and fetuses admitted to the Pretoria Medico-Legal Laboratory (PMLL) in South Africa. ⋯ A comparatively large number of cases were found to have been admitted to the Pretoria Medico-Legal Laboratory. This is alarming because South African abortion laws are liberal and services are free at point of access in the public health care sector. A substantial percentage of cases of abandoned infants were found to have shown signs of life after birth implying a homicidal manner of death or death by abandonment, but it seems these cases are merely shelved.

We present a case of fatal intoxication by the application of a transdermal fentanyl patch upon a superficial bleeding abrasion of a 2-year-old girl. The grandmother discovered the body of the child in bed at approximately 7 a.m. External examination revealed a properly developed, nourished, and hydrated child, with some vomit in the nostrils and inside the mouth. ⋯ Although fatal intoxications are uncommon among young children in high-income countries, it is of major interest to raise awareness of such events especially since a great majority of these are preventable. The presented case points at the need for more thorough education of users and more strict rules in prescribing and handling of this potent medicine. As well, we find this case to be a useful contribution to the evaluation of postmortem fentanyl concentrations in fatal intoxication in a small child.
