Review Historical ArticleRole of forensic pathologists in mass disasters.
The forensic pathologist has always had a central role in the identification of the dead in every day practice, in accidents, and in disasters involving hundreds or thousands of victims. This role has changed in recent years, as advances in forensic odontology, genetics and anthropology have improved the chances of identifying victims beyond recognition. According to the Interpol DVI Guide, fingerprints, dental examination and DNA are the primary identifiers, and this has given new emphasis to the role of the forensic pathologist as the leader of a multidisciplinary team of experts in a disaster situation, based on his or her qualifications and the experience gained from doing the same work in the everyday situation of an institute of forensic medicine.

Case ReportsForensic and psychiatric aspects of joint suicide with carbon monoxide.
A case of joint suicide of a young woman and man who became acquainted in a suicide web forum and used this platform to make an appointment to commit suicide together is described. During their investigation, police were able to reconstruct the events by analysing the computer of the deceased women which was also found with the bodies. An indoor charcoal burning unit was used to release carbon monoxide as the method of suicide.

Case ReportsFatal spontaneous subdural bleeding due to neonatal giant cell hepatitis: a rare differential diagnosis of shaken baby syndrome.
A 7-week-old girl showed vomiting after feeding, facial pallor, loss of muscle tone and respiratory depression. An emergency doctor performed successful resuscitation and after arrival in hospital, cranial ultrasound showed left-sided subdural hemorrhage, cerebral edema with a shift of the midline, and a decrease in cerebral perfusion. Ophthalmologic examination showed retinal hemorrhage. ⋯ Autopsy verified subdural hemorrhage, cerebral edema and retinal hemorrhage, but also revealed intact bridging veins and a lack of optic nerve sheath hemorrhage, therefore shaken baby syndrome could not be proven by autopsy. Histological examination showed severe neonatal giant cell hepatitis as the cause of the severe coagulopathy and the associated spontaneous subdural bleeding. Neonatal giant cell hepatitis may be responsible for unexpected deaths in infancy and, although rarely associated with subdural bleeding, must be considered as a potential differential diagnosis of shaken baby syndrome.

ReviewReview: Pharmacogenetic aspects of the effect of cytochrome P450 polymorphisms on serotonergic drug metabolism, response, interactions, and adverse effects.
The field of pharmacogenetics contains a wealth of potential for the enhancement of clinical practice by providing a more effective match between patient and drug, consequently reducing the probability of an adverse drug reaction. Although a relatively novel concept in the forensic context, pharmacogenetics has the capability to assist in the interpretation of drug related deaths, particularly in unintentional drug poisonings where the cause of death remains unclear. However, the complex pharmacology of the drugs when subjected to genetic variations in metabolism makes interpretation of the expected response and adverse events difficult. ⋯ A number of these drugs, which are metabolised primarily by the CYP450 system, are also associated with serotonin syndrome, or serotonin toxicity, especially when used concomitantly with other serotonin active drugs which rely on the same metabolic pathways for drug elimination. A comprehensive understanding of polymorphic drug metabolism and its expected outcomes is therefore essential when interpreting the involvement of drugs in adverse reactions. This review examines the genetically variable CYP450-mediated metabolism of a number of serotonin-active drugs that are often implicated in cases of serotonin toxicity, to assess the impact of pharmacogenetics on drug metabolism, response, interactions and adverse effects.

Deaths resulting from the use of black powder handguns are relatively uncommon compared to other firearms. We report the case of a 48 year-old woman who sustained a lethal gunshot wound to the face from a black powder revolver. ⋯ The exit wound also contained evidence of soot. Discussion of this characteristic pattern of discharge deposition from black powder weapons is presented.
