The cellular immune response is accompanied by the release of neopterin. The level of neopterin in serum is increased in patients suffering from viral infections, autoimmune diseases, systemic inflammation, allograft rejection and malignant diseases, while that of C-reactive protein (CRP) is known to rise during inflammatory diseases and traumas. To investigate postmortem neopterin and CRP concentrations with regard to the cause of death, we examined cardiac and peripheral blood samples in 474 autopsy cases without advanced decomposition (0-96 years of age, 343 males and 131 females), 2.8 h to 3 days (median, 18.0 h) after death. ⋯ For sepsis, the serum CRP level was markedly elevated but the neopterin level was low in some cases. Fatal viral infections usually resulted in a marked elevation in the serum neopterin level (>500 nmol/l) with a mild to moderate rise in the CRP level. Combined analyses of neopterin and CRP may be useful to investigate viral infections and delayed traumatic death involving SIRS to support pathological findings.

The Section of Forensic Medicine at the University of Copenhagen performs age evaluations of the living at the request of the police. The established procedure in these cases involves: (1) a physical examination; (2) an odontological examination based on evaluation of an orthopantomogram and intraoral dental radiographs. Different methods are used depending on the maturity of the individual examined; and (3) a carpal X-ray examination, using the Greulich and Pyle Atlas (GPA) method. ⋯ Indeed, we found a minor difference in the age estimations for older juveniles between odontologists and radiologists, which may indicate that more studies on comparative dental and skeletal aging for geographically different populations would be beneficial. Finally, if using the GPA method in legal cases, we would advise that one should closely adhere to the standard deviations given, and intermediary scores should be noted and not just a resultant age. The final age statement should also address the problems of reference populations.

Shooting range injuries are generally caused by ballistic accidents, and so far no burn disaster has been reported. In this article we reported a disaster caused by a gunpowder explosion in an indoor shooting range area in Istanbul, Turkey. Fourteen injured people were evacuated from the scene. ⋯ Of the 7 injured people, 2 who were accepted by our burn center, and 3 people who were admitted by another center died. It is clearly identified how this mechanism of injury differs from that of usual burn injuries, due to both the high temperature generated, and the combination of hot and toxic gases produced by the explosion. We described the features of burn injury, and possible reasons of burn disasters.
