Abstract

Determining the time since death of an individual from skeletal remains is a challenging stage. In determination of time since death, climate conditions, environmental factors, conditions such as whether the body was buried or not, and genetic and personal factors must be evaluated all together. With these factors changing and with the exposure duration growing longer, changes occur in the morphology of the bone might increase. In this study, as part of an investigation, bones which had been found in a water-well during an excavation work in Mardin was used. After 36 pieces of bone that belong to a human were analyzed, it was found that the bones had lost most of their weight and density, that they were considerably fragile, that their medulla was emptied, and that there were intense erosions on the surfaces of bony tissue. While under normal circumstances and under the condition that it was a buried body it would take at least 50 years for these changes to occur, considering that the bones remained in water for a very long time, the corrosion had to be much more than expected. With the DNA comparison, it was found that the bones belonged to people who were claimed to have been killed in the 90s. In this study, it was aimed to determine the time of death of remains which were reported to have stayed in contact with water, and to study the effect of the environmental circumstances in which the bodies are found on the bones.

Abstract

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., Highlights • CMV may lead to fatal disseminated CMV infection of the premature and newborn. • Our study is the first comprehensive study investigating CMV infections in SUDI. • CMV suppresses the immune system, and may predispose to other infections. • Postmortem molecular investigations are useful in explaining cause of death in SUDI.

Abstract

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.
