Abstract
Pneumonia is one of the most common causes of children's hospitalization and death. The aim of the study was a medico-legal analysis of children who died suddenly due to pneumonia undiagnosed in their lifetime. The research was of a retrospective character and consisted in an analysis of prosecution files. The study included 47 children who died between 2011-2018 in whom pneumonia after post-mortem examination was indicated as the cause of death, as well as children in whom the cause of death, despite additional post-mortem examinations, including histopathological tests, was not established. In some cases, under additional post-mortem examinations, additional targeted immunohistochemical staining of selected lung sections was performed to establish the diagnosis. In children with prodromal symptoms, histopathological examination showed significantly more frequent atelectasis than in children without prodromal symptoms. Pneumonia is a significant clinical problem. Especially in young children, it may proceed with- out any symptoms that would cause such a diagnosis to be made. A properly conducted post-mortem diagnosis supplemented by immunohistochemical examinations allows to reduce the number of unexplained deaths in children.

Abstract
Death due to respiratory infection is commonly encountered at autopsy. With only one opportunity to obtain samples for identification of a causative agent, it is important to ensure that sampling regimes are optimized to provide the greatest detection, without the expense and redundancy that can arise from over-sampling. This study was performed retrospectively using data from Coronial autopsies over the period 2012–2019 from which swabs from the nasopharyngeal region, trachea and lung parenchyma, in addition to samples of lung tissue, had been submitted for multiplex PCR detection of respiratory pathogens. From 97 cases with all four samples, there were 24 with at least one positive result for viral infection. Some cases had multiple positive results and a total of 27 respiratory tract viruses were identified, of which rhinovirus, influenza A virus and respiratory syncytial virus were the most common. Seventeen of the 27 viral infections (63%) were identified in all four samples. However, in nearly all cases (96%) the nasopharyngeal swab detected the infective agent when the multiplex PCR panel had detected infection in any of the four sample types. A nasopharyngeal swab is considered to be an optimal sample for detection of respiratory tract viral infection. As the samples analyzed were acquired before the appearance of the COVID-19 virus, the applicability of this finding for COVID-19 screening is not established.

Post-mortem microbiology in sudden death: sampling protocols proposed in different clinical settings. Clin Microbiol Infect 2018; 25:570-579. [PMID: 30145399 DOI: 10.1016/j.cmi.2018.08.009] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2018] [Revised: 07/10/2018] [Accepted: 08/11/2018] [Indexed: 12/13/2022]
Abstract
BACKGROUND Autopsies, including minimally invasive autopsies, are a powerful tool for determination of the cause of death. When a patient dies from an infection, microbiology is crucial to identify the causative organism. Post-mortem microbiology (PMM) aims to detect unexpected infections causing sudden deaths; confirm clinically suspected but unproven infection; evaluate the efficacy of antimicrobial therapy; identify emergent pathogens; and recognize medical errors. Additionally, the analysis of the thanatomicrobiome may help to estimate the post-mortem interval. AIMS The aim was to provide advice in the collection of PMM samples and to propose sampling guidelines for microbiologists advising autopsy pathologists facing different sudden death scenarios. SOURCES A multidisciplinary team with experts in various fields of microbiology and autopsies on behalf of the ESGFOR (ESCMID - European Society of Clinical Microbiology and Infectious Diseases - study group of forensic and post-mortem microbiology and in collaboration with the European Society of Pathology) developed this narrative review based on a literature search using MedLine and Scopus electronic databases supplemented with their own expertise. CONTENT These guidelines address measures to prevent sample contamination in autopsy microbiology; general PMM sampling technique; protocols for PMM sampling in different scenarios and using minimally invasive autopsy; and potential use of the evolving post-mortem microbiome to estimate the post-mortem interval. IMPLICATIONS Adequate sampling is paramount to identify the causative organism. Meaningful interpretation of PMM results requires careful evaluation in the context of clinical history, macroscopic and histological findings. Networking and closer collaboration among microbiologists and autopsy pathologists is vital to maximize the yield of PMM.
