Atherosclerosis is a chronic inflammatory disease creating calcifying plaques in the arterial walls. Because its paleopathological diagnosis remains little studied on skeletal remains, its impact on forensic and archeological data is completely underestimated. Here, 24 skeletal remains from the Milano Cemetery Skeletal Collection have been studied to evaluate the chance of atherosclerotic calcification survival, retrieval, and identification. Through direct comparison with a known autopsy collection and literature, the identification and categorization of several types of calcifications were performed...

Endocan is a soluble molecule secreted from vascular endothelial cells of various organs. Its exact function in humans remains to be elucidated, though it has been postulated that increased tissue expression or serum levels of this molecule may be an indicator of endothelial activation and neovascularization. In the realm of forensic pathology, studies pertaining to endothelial activation following exposure to cold exclusively focused on thrombomodulin, a transmembrane protein specific to endothelial cells...

Ascertaining the vital origin of skin wounds is one of the most challenging problems in forensic pathology. The forensic literature describes biomarkers and methods for differentiating vital and postmortem wounds, although no clear conclusions have been reached. The aim of this study was to characterize human vital wounds by analyzing the concentrations of metallic ions and the expression of P-selectin and cathepsin D in skin wounds in the ligature marks in a cohort of suicidal hangings for which vitality was previously demonstrated...

Analysis of homicidal insulin overdose is a challenging task in forensic practice because of the difficulties in toxicological analysis as well as the elusive pathologic changes. We performed a detailed histopathologic examination on four autopsy cases involving insulin homicide, using H&E, immunohistochemistry (IHC) and immunofluorescence assays. Severe reactive astrocyte proliferation was obvious in the white matter of the cerebrum, corpus callosum, cerebellum and brain stem, especially in subcortical regions...

Forensic pathology is a specialty that involves death investigation while clinical forensic medicine is the application of the practice of medicine to the requests of the law in relation to the living. Around the world, there is diverse practice for these two disciplines. The forensic physician or forensic doctor (sometimes, called a forensic pathologist but not a forensic histopathologist) in parts of the world such as continental Europe, the Middle East and India, practice both clinical forensic medicine and forensic pathology...

Estimation of postmortem interval (PMI) is a key issue in the field of forensic pathology. With the availability of quantitative analysis of RNA levels in postmortem tissues, several studies have assessed the postmortem degradation of constitutively expressed RNA species to estimate PMI. However, conventional RNA quantification as well as biochemical and physiological changes employed thus far have limitations related to standardization or normalization. The present study focuses on an interesting feature of the subdomains of certain RNA species, in which they are site-specifically cleaved during apoptotic cell death...

The word "autopsy" denotes "to see with own eyes." Autopsy (postmortem) is a process that includes a thorough examination of a corpse noting everything related to anatomization, surface wounds, histological and culture studies. Virtopsy is a term extracted from two words "virtual" and "autopsy." It employs imaging methods that are routinely used in clinical medicine such as computed tomography and magnetic resonance imaging in the field of autopsy, to find the reason for death. Virtopsy is a multi-disciplinary technology that combines forensic medicine and pathology, roentgenology, computer graphics, biomechanics, and physics...

BACKGROUND: Stanford acute type A aortic dissection (ATAAD) is a potentially lethal condition. Epidemiology studies show a statistical incidence in Europe of approximately 2-16 cases/100,000 inhabitants/year. In Germany, the estimated incidence (here subsumed under "thoracic aortic dissection" with 4.63 cases/100,000 inhabitants/year) is mainly extracted from medical death certificates by the German Federal Statistical Office. The prehospital incidence of ATAAD deaths is largely unknown...

Hanging is violent asphyxial death. The objective of this study is to assess the data of hanging cases. A descriptive-retrospective study was conducted. We studied 244 hanging cases autopsied in Forensic Division, Department of Pathology, Faculty of Medicine Ramathibodi Hospital, Mahidol University, Bangkok, Thailand, between January 2001 and December 2013. The study included 197 men (80.7%) and 47 women (19.2%). Their age ranged from 14 to 93 years. Most of these cases were incomplete hanging (83.6%). Features of hanging victims, such as tongue protrusion; congestion of face; petechial hemorrhage of face, conjunctiva, and internal organs; and neck injuries, significantly correlated with complete hanging...

Immersion Pulmonary Edema (IPE) reduces the transport of gases over the respiratory membrane due to edema in the interstitium and respiratory zones. IPE has previously been described in both swimmers and divers, with a few known fatal cases. We have reviewed 42 SCUBA and snorkeling-related drowning deaths, and through a thorough analysis of each case, including both diving physiology and forensic pathology, we present IPE as a differential diagnosis to drowning in four cases. Our findings propose that; absence of watery content in the stomach and conducting airways, and liquid filled lungs without hyperexpansion, may be compatible with IPE...

BACKGROUND: Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is a primary cardiomyopathy characterised by fibrofatty replacement and ventricular arrhythmias. The occurrence of malignant arrhythmias may be associated with fatty infiltration and intercalated disk remodelling, but the specific pathological remodelling pattern is not yet clear. METHODS: Twelve explanted hearts from patients diagnosed with ARVC/D according to the 2010 Task Force Criteria and pathology examination were divided into two groups with (SVT, n=6) or without (non-SVT, n=6) recurrent sustained ventricular tachycardia (SVT) before heart transplantation...

In the clinical setting, the role of systemic inflammation in patients with asthma has attracted increased attention, and some authors showed that increased IL-6 and high-sensitivity C-reactive protein characterized a group of asthmatic patients. In the realm of forensic pathology, a postmortem diagnosis of asthmatic death can be extremely challenging. The aim of this study was to determine the postmortem serum levels of C-reactive protein, IL-6, and tumor necrosis factor α in a series of severe acute bronchial asthma deaths that underwent medicolegal investigations...

AIM: To determine whether antemortem blood levels of glycated hemoglobin (HbA1c) and glucose predict completed suicide and, by extension, whether markers of glucose metabolism might be associated with a prosuicidal trait or state. METHOD: From consecutively performed autopsies, samples of blood and vitreous humor from 17 suicide victims and 27 non-suicide controls were compared with regard to levels of glucose, lactate, and HbA1c. RESULTS: Mean HbA1c was higher, and mean estimated blood glucose lower, among suicide victims, although tests revealed no significant differences (P=0...

BACKGROUNDS: Aortic rupture or dissection as immediate cause of sudden death is encountered in forensic and clinical autopsy practice. Despite a common denominator of 'sudden aortic death' (SAD), we expect that in both settings the diagnostic workup, being either primarily legal or primarily disease related, differs substantially, which may affect the eventual diagnoses. METHODS: We retrospectively reviewed case records of deceased persons who fitted a diagnosis of SAD in the continuous autopsy cohorts in a forensic (Suisse) and a clinical setting (The Netherlands)...

Post-mortem microbiology (PMM) is an important tool in forensic pathology, assisting to determine the cause and manner of death. However, there is a lack of standardisation of PMM sampling. In order to get a better insight into the methods used, the available technical options and developmental needs, ESCMID Study Group for Forensic and Postmortem Microbiology (ESGFOR) members designed a survey aimed at pathologists regarding common practices of PMM in clinical and forensic autopsies. Multiple choice questions were developed based on Cumulative Techniques and Procedures in Clinical Microbiology (Cumitech)...
