Parricide cases of adult offenders from Turkey: A descriptive study.

The aim of this study was to examine and compare similarities and differences among types of parricide committed by adult offenders. The forensic psychiatric evaluation reports of the 4th Specialization Board of the Council of Forensic Medicine from 2009 to 2011 in Turkey were screened retrospectively. One hundred thirty-five adult perpetrators of parricide (125 male, 10 female) were detected, 51.9% of whom committed patricide, 40% of whom matricide and 8.1% of the perpetrators committed double parricide. Most of the perpetrators used sharp instruments as the killing method. No mental disorders were detected in 58.5% of the perpetrators, while psychotic disorders were identified in 30.4% of the cases. This study supported the predominance of sharp instruments as the killing method and a preponderance of matricide among the offenders with psychotic disorders. Although psychotic disorders were the most commonly detected mental disorders in the parricide offenders, most of them did not suffer from mental disorders.

An experimental evaluation of electrical skin conductivity changes in postmortem interval and its assessment for time of death estimation.

In forensic medicine, estimation of the time of death (ToD) is one of the most important and challenging medico-legal problems. Despite the partial accomplishments in ToD estimations to date, the error margin of ToD estimation is still too large. In this study, electrical conductivity changes were experimentally investigated in the postmortem interval in human cases. Electrical conductivity measurements give some promising clues about the postmortem interval. A living human has a natural electrical conductivity; in the postmortem interval, intracellular fluids gradually leak out of cells. These leaked fluids combine with extra-cellular fluids in tissues and since both fluids are electrolytic, intracellular fluids help increase conductivity. Thus, the level of electrical conductivity is expected to increase with increased time after death. In this study, electrical conductivity tests were applied for six hours. The electrical conductivity of the cases exponentially increased during the tested time period, indicating a positive relationship between electrical conductivity and the postmortem interval.

Postmortem diagnosis of cytomegalovirus and accompanying other infection agents by real-time PCR in cases of sudden unexpected death in infancy (SUDI).

As an opportunistic pathogen with high mortality rates, Cytomegalovirus (CMV) may lead to fatal disseminated CMV infection of the premature and newborn; thus necessitating the demonstration of CMV-DNA with clinical history and/or histopathological findings of CMV infection and defining other bacterial and viral infection agents with real-time polymerase chain reaction (RT-PCR) in udden unexpected death in infancy (SUDI) cases as we aimed in this study. 314 (144 female, 170 male) SUDI cases were prospectively investigated from January 2013 to January 2015 in Istanbul Forensic Medicine Institution. The study includes 87 tissue samples of 39 cases for post-mortem histopathological examination of interstitial pneumonia, myocarditis, meningitis, encephalitis, hepatitis, colitis or tubulointerstitial nephritis and/or accompanying chronic sialadenitis. CMV-DNA was found positive in 35 (40.2%) salivary gland, 19 (21.8%) lung, 1 (1.1%) tonsil, and 1 (1.1%) brain tissues. CMV sialadenitis and/or CMV pneumonia associated with other viral and/or bacterial agents were detected in 23 (60%) of 39 infant cases. The demonstration of CMV-DNA would significantly clarify the cause of death and collection of epidemiological data in SUDI cases with clinical history and histopathological findings of CMV infection accompanying chronic CMV sialadenitis. Furthermore, CMV suppresses the immune system, and may predispose to other bacterial and/or viral infections in these cases. Post-mortem molecular investigations are useful in explaining cause of death in SUDI with a suspicion of infection in forensic autopsies.

[An Autopsy Case of Sudden Death Caused by Cerebral Malaria Infection]. / Serebral Malarya Enfeksiyonuna Bagli Ani Ölümle Sonuçlanan Otopsi Olgusu.

Malaria is a lethal protozoan infection which is generally diagnosed antemortem and rarely diagnosed postmortem in a few cases. A fifty five year old, Turkish citizen male has been referred for autopsy. It has been found that he has gone abroad to work a month ago, however, quitted malaria prophylaxis before the intended end and brought into the emergency department in an unconscious state.Following quinine and clindamycin treatment with the initial diagnosis of cerebral malaria, the case was reported to have died due to his general condition got worsened at the end of the third day of therapy.Histopathological evaluation of postmortem tissues was revealed haphazardly arranged minor bleedings and central vascular necrotic foci in the cerebrum, cerebelum and brain stem; light brown pigment containing cells around vasculature; and pigment containing cells in the spleen and bone marrow. Cerebral malaria has a rapid course and is rare but one of the lethal complications of infections with Plasmodium. Although domestic malaria cases has been decreasing in our country, it should be kept in mind that the malaria infection can be seen in persons travelling abroad to high endemic malarial regions and an appropriate antimalarial prophylaxis should be recommended to those overseas travellers.
