Pathological Findings in COVID-19 as a Tool to Define SARS-CoV-2 Pathogenesis. A Systematic Review
Introduction: The World Health Organization declared the COVID-19 pandemic in March 2020. COVID-19 still represents a worldwide health emergency, which causesa severe disease that has led to the death of many patients. The pathophysiological mechanism of SARS-CoV-2 determining the tissue damage is not clear and autopsycan be auseful tool to improve the knowledge of this infection and, thus, it can help achieve a timely diagnosis and develop an appropriate therapy. This is an overview of the main post-mortem findings reporting data on the infection effects on several organs.Methods: A systematic literature search was conducted in the PubMed database searching for articles from 1 January to A…
Caspase 9 and Caspase 3 Immunohistochemical Reactivity Pattern in Skeletal and Cardiac Muscle at Different Times After Death: A New Tool for Postmortem Interval (PMI) Determination?
Learning Overview: After attending this presentation, attendees will understand the importance of the identification of new markers that could be used as possible PMI indicators, especially in contexts in which the reliance on the classic thanatochronological triad—livor, rigor, and algor mortis—is not conclusive. Impact on the Forensic Science Community: This presentation will impact the forensic science community by highlighting the relationship between the activation pattern of caspases 9 and 3 on skeletal and cardiac muscle samples and PMI. The determination of the amount of time elapsed from one’s death to the recovery of the body—the so-called PMI—has always relied on the evaluation o…
Fire in operating room: The adverse "never" event. Case report, mini-review and medico-legal considerations.
Abstract The patient’s security and safety represent a topic of great importance for public health that led several healthcare organizations in many Countries to share documents to promote risk management and preventing adverse events. Surgical Fire (SF) is an infrequent adverse event generally occurring in the operating room (OR) and consisting of a fire that occurs in, on, or around a patient undergoing a medical or surgical procedure. Here a medico-legal case involving a 65-year-old woman reporting burns to the neck due to an SF during a thyroidectomy was described. A literature review was performed using Pubmed and Scopus databases, focusing on epidemiology, causes, prevention activitie…
A unique fatal case of Waterhouse–Friderichsen syndrome caused by Proteus mirabilis in an immunocompetent subject
Abstract Introduction: The Waterhouse–Friderichsen syndrome (WFS), also known as purpura fulminans, is a potentially lethal condition described as acute hemorrhagic necrosis of the adrenal glands. It is often caused by infection. Classically, Neisseriae meningitidis represents the main microorganism related to WFS, although, infrequently, also other infectious agents are reported as a possible etiologic agent. The authors report the first case of death due to Proteus mirabilis infection, with postmortem evidence of WFS. Patient concerns: After a facial trauma that provoked a wound on the nose, the subject, a healthy 40-years old man, was conducted to the local hospital (in Sicily, Italy) af…
