Part 1 of the review "Back to the Future" examines the historical evolution of the medico-legal autopsy and microscopy techniques, from Ancient Civilization to the Post-Genomic Era. In the section focusing on "The Past", the study of historical sources concerning the origins and development of the medico-legal autopsy, from the Bronze Age until the Middle Ages, shows how, as early as 2000 BC, the performance of autopsies for medico-legal purposes was a known and widespread practice in some ancient civilizations in Egypt, the Far East and later in Europe...

BACKGROUND: In recent years, tourism has become the number one account for foreign exchange income in Iceland, overtaking the fisheries industry and aluminium production. The rise of tourism has strongly affected Icelandic society in various sectors. With the increase of tourists visiting Iceland, the number of foreign citizens that died and were autopsied also rose. METHOD: Data were collected from the Department of Forensic Pathology at Landspitali University Hospital in Reykjavik for the period January 2006 - December 2016...

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)...

Personalized medicine (PM), included in P5 medicine (Personalized, Predictive, Preventive, Participative and Precision medicine) is an innovative approach to the patient, emerging from the need to tailor and to fit the profile of each individual. PM promises to dramatically impact also on forensic sciences and justice system in ways we are only beginning to understand. The application of omics (genomic, transcriptomics, epigenetics/imprintomics, proteomic and metabolomics) is ever more fundamental in the so called "molecular autopsy"...

Causes of sudden cardiac deaths have been widely reported with limited data focused specifically on myocarditis. A retrospective review of cases from the Office of the Chief Medical Examiner (OCME), State of Maryland yielded a total of 103 sudden unexpected deaths (SUDs) due to myocarditis (0.17% of all SUDs and 0.70% of autopsied SUDs) from 2005 through 2014. Most deaths occurred in patients <30 years of age with a male:female ratio 1.3:1. Of the 103 cases, 45 (43.7%) patients were witnessed collapsed. Four deaths occurred during exertion, such as exercising at the gym or performing heavy physical work, and 2 deaths were associated with emotional stress...

We investigated 998 serial Japanese forensic autopsy cases (0-101 years old, mean age 61.7 ± 21.9), with no case selection, using immunohistochemistry to detect cases with progressive supranuclear palsy (PSP). Twenty-nine cases (mean age 82.3 ± 7.2 years, 11 males, 18 females) fulfilled the National Institute of Neuronal Disorders and Stroke (NINDS)-PSP pathological criteria (2.9% of all cases, 4.6% of cases over 60). All had neuronal and glial inclusions in the basal ganglia and brainstem. However, 13 cases had low tau pathology and were categorized as atypical PSP...

PURPOSE: Multi-phase post-mortem computed tomography angiography (MPMCTA) is a new diagnostic tool, used in forensic pathology. On the one hand, this technique allows a better and direct visualization of vascular and solid organ lesions. On the other hand, the invasiveness of the procedure-which requires surgical denudation (inguinal and/or cervical) and the insertion of surgical cannulas-leads to many relatives refusing scientific autopsies. Our hypothesis states that a minimally-invasive procedure combining interventional radiological techniques with MPMCTA (replacement of surgical cannulas by radiological catheters) will improve the approval rate of scientific autopsies by families...

Venous thromboembolism (VTE) is a multifactorial disease determined by a combination of inherited and acquired factors. Inherited factors include mutations in the genes coding for coagulation factors, some of which seem to exert a differential influence on the risk of developing deep vein thrombosis (DVT) and pulmonary embolism (PE). In post-mortem studies of subjects who have died from pulmonary embolism (PE), the analysis of the factors that may have augmented the VTE risk is often limited to acquired factors...

An accurate and precise documentation of injuries is fundamental in a forensic pathological context. Photographs and manual measurements are taken of all injuries during autopsies, but ordinary photography projects a 3D wound on a 2D space. Using technologies such as photogrammetry, it is possible to create 3D detailed, to-scale, true-color documentation of skin injuries from 2D pictures. A comparison between the measurements of 165 lesions taken during autopsies and on photogrammetrically processed pictures was performed...

PURPOSE: The aim of this study was to assess whether the identification of pathological myocardial enhancement at multiphase postmortem computed tomography angiography was correlated with increased levels of troponin T and I in postmortem serum from femoral blood as well as morphological findings of myocardial ischemia. We further aimed to investigate whether autopsy cases characterized by increased troponin T and I concentrations as well as morphological findings of myocardial ischemia were also characterized by pathological myocardial enhancement at multiphase postmortem computed tomography angiography...

The objective of the present study was to analyze the causes of sudden death in the general population and in the fraction of the young subjects (below 39 years of age). The results of the original retrospective study were obtained in the course of forensic medical autopsies of the subjects aged below 39 years that had been carried out during a period of 10 years. It was shown that one of the causes behind sudden death among the young subjects is cardiovascular disorders associated with the pre-existing pathological condition in the form of connective tissue dysplasia...

The rate for the sudden infant death syndrome (SIDS) in Cape Town, South Africa, is estimated to be among the highest in the world (3.41/1000 live births). In several of these areas, including those of extreme poverty, only sporadic, nonstandardized infant autopsy, and death scene investigation (DSI) occurred. In this report, we detail a feasibility project comprising 18 autopsied infants with sudden and unexpected death whose causes of death were adjudicated according to the 1991 NICHD definitions (SIDS, n = 7; known cause of death, n = 7; and unclassified, n = 4)...

INTRODUCTION: Among 800 burials dated between the 15th and 18th centuries and found in the center of Rennes (Brittany, France), a collection of five heart-shaped lead urns was discovered. This material was studied using classical methods (external study, autopsy and histology), and also modern imaging like computed tomography (CT), magnetic resonance (MR) before and after coronary opacification. The aim of this manuscript is to describe different steps of ancient soft tissues study, especially using imaging techniques...

Pulmonary edema is a common finding in fatal methamphetamine intoxication. However, the underlying mechanism remains poorly understood. This study investigated the molecular pathology of alveolar damage involving pulmonary edema in forensic autopsy cases. Seven candidate reference genes (RPL13A, YWHAZ, GUSB, SDHA, GAPDH, B2M, and ACTB) were evaluated in the lung by the geNorm module in qBase(plus) software. RPL13A, YWHAZ, and GUSB were identified as the most stable reference genes. Using these validated reference genes, intrapulmonary mRNA expressions of matrix metalloproteinases (MMPs), intercellular adhesion molecule-1 (ICAM-1), claudin-5 (CLDN-5), and aquaporins (AQPs) were examined...
