A unique case of accidental hanging due to compression of the neck of an adult by the branches of a coffee tree is reported. The decedent was a 42-year-old male who was found dead in a semi prone position on a slope. His neck was lodged in a wedge formed by two branches of a coffee tree, with his legs angled downwards on the slope. Autopsy revealed two friction abrasions located horizontally on either side of the front of the neck, just above the larynx. The findings were compatible with compression of the neck by the branches of the tree, with the body weight of the decedent contributing to compression...

Post mortem computed tomography (PMCT) can be used as a triage tool to better identify cases with a possibly non-natural cause of death, especially when high caseloads make it impossible to perform autopsies on all cases. Substantial data can be generated by modern medical scanners, especially in a forensic setting where the entire body is documented at high resolution. A solution for the resulting issues could be the use of deep learning techniques for automatic analysis of radiological images. In this article, we wanted to test the feasibility of such methods for forensic imaging by hypothesizing that deep learning methods can detect and segment a hemopericardium in PMCT...

Deaths involved with environmental hazards and intoxication might present with minimal or nonspecific morphological features, which are insufficient to establish a diagnosis. The present study investigated the postmortem brain mRNA and immunohistochemical expressions of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), inducible nitric oxide synthase (iNOS) and nuclear factor erythroid-2-related factor-2 (Nrf2) in forensic cases. Relative mRNA quantification using Taqman real-time PCR assay demonstrated higher expression of IL-1β, TNF-α and iNOS, and lower expression of Nrf2 in methamphetamine intoxication and hyperthermia cases, higher expression of iNOS in phenobarbital intoxication cases, and higher expression of Nrf2 in phenobarbital intoxication and hypothermia cases...

Cardiopulmonary resuscitation (CPR) can create a range of unusual lesions and injuries, which may complicate forensic evaluation. Although potentially sinister findings, neck injury and conjunctival petechiae may also be seen in patients who have undergone CPR. We report a case of an individual with subcutaneous bruising and hemorrhage in the deep structures of the neck and florid conjunctival petechiae at autopsy that can be explained by cardiopulmonary resuscitation and meningococcal sepsis.

Sudden cardiac death (SCD) is a major health challenge. The records of 769 autopsy cases of SCD examined at Tongji Medicolegal Expertise Center from January 2006 to December 2015 were retrospectively reviewed. The mean age of the cases was 46 years, excluding 27 victims in whom the exact age could not be confirmed. The highest incidence of SCD occurred among the 40- to 60-year-old group (45.0%). Male preponderance was observed in SCD cases (male: female ratio: 5.0:1), and this preponderance was even higher (8...

Although death from food is not an uncommon finding in forensic facilities worldwide, the range of underlying lethal mechanisms and associated conditions that should be sought at the time of autopsy is quite disparate. Deaths may occur from i) infectious agents including bacteria, viruses, protozoa, cestodes, nematodes and prions; ii) natural toxins including amanita toxins, tetrodotoxin, ciguatera and scombroid; iii) anaphylaxis; iv) poisoning; v) mechanical issues around airway and gut obstruction and/or perforation; and vi) miscellaneous causes...

Toxic leukoencephalopathy represents a process of structural alteration of the white matter. It is caused by substance abuse including drugs such as heroin, cocaine, toluene and ethanol. We reported the clinical, radiological and autopsy findings of a rare case of toxic leukoencephalopathy following chronic methamphetamine (MA) usage. A 34-year-old man with a 3-year history of MA abuse experienced progressive sluggish state, limb weakness, inability to stand and eating disorders, followed by rapid progression to coma and death...

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...

There is growing awareness of sudden unexplained death in alcohol misuse (SUDAM) in which there is no obvious cause of death, no evidence of acute alcohol toxicity or alcoholic ketoacidosis, and the heart is morphologically normal. This study describes the characteristics of a cohort with SUDAM from a tertiary cardiovascular referral center and compares the findings with those of individuals who died from sudden arrhythmic death syndrome (SADS). Cases in this retrospective cross-sectional study were identified from a database of referrals to our center spanning approximately 40 years...

Despite widely accepted standards for sampling and preservation of insect evidence, unrepresentative samples or improperly preserved evidence are encountered frequently in forensic investigations. Here, we report the results of laboratory studies on the survival of Lucilia sericata and Calliphora vomitoria (Diptera: Calliphoridae) intra-puparial forms in hermetic containers, which were stimulated by a recent case. It is demonstrated that the survival of blowfly intra-puparial forms inside airtight containers is dependent on container volume, number of puparia inside, and their age...

The stimulant designer drug 3,4-methylenedioxypyrovalerone (MDPV) was first synthesized by Boehringer Ingelheim in 1969 and introduced on the black market in 2006. Only a small number of fatal intoxication cases have been reported in the literature, all with significant blood MDPV concentrations. In this report, we describe one fatality attributed to an idiosyncratic reaction to MDPV. The victim displayed agitation, violent behavior and delirium followed by cardiac arrest. Hyperthermia was observed at the hospital...

Caffeine is not usually perceived as a drug by most people because it is found in many foods and drinks, including caffeinated energy drinks, as well as in over the counter analgesics and cold preparations. Recently in Poland it has become increasingly common to take pure caffeine, bought through online stores, as a psychoanaleptic. This creates a much higher risk of severe and even fatal poisoning in comparison with the risk associated with the abuse of food products and non-prescription medicines containing low doses of caffeine...
