Review
Fetal and perinatal autopsies are useful to identify the accurate cause of death and in the process recognize disorders which may require counselling for future pregnancies. Abnormalities of the CNS are an important cause of fetal loss and perinatal deaths. Most of these are structural abnormalities of the CNS, however a smaller portion show changes pertaining to prematurity, infections and even congenital tumors. In this review we evaluate CNS abnormalities of the fetus and the newborn as detected in autopsy series. We also describe our experience in a tertiary care hospital with a specialized neonatology unit over the last 8 years and discuss some of the newer methods like virtual autopsy.

Review
Historically, autopsy contributed to our current knowledge of cardiovascular anatomy, physiology, and pathology. Major advances in the understanding of cardiovascular diseases, including atherosclerosis and coronary artery disease, congenital heart diseases, and cardiomyopathies, were possible through autopsy investigations and clinicopathological correlations. In this review, the importance of performing clinical autopsies in people dying from cardiovascular disease, even in the era of advanced cardiovascular imaging is addressed. Autopsies are most helpful in the setting of sudden unexpected deaths, particularly when advanced cardiovascular imaging has not been performed. In this setting, the autopsy is often the only chance to make the correct diagnosis. In previously symptomatic patients who had undergone advanced cardiovascular imaging, autopsies still play many roles. Post-mortem examinations are important for furthering the understanding of key issues related to the underlying diseases. Autopsy can help to increase the knowledge of the sensitivity and specificity of advanced cardiovascular imaging modalities. Autopsies are particularly important to gain insights into both the natural history of cardiovascular diseases as well as less common presentations and therapeutic complications. Finally, autopsies are a key tool to quickly understand the cardiac pathology of new disorders, as emphasized during the recent coronavirus disease 2019 pandemic.

Irish Journal of Medical Science Apr 2022The aim of this study is to share autopsy findings of COVID-19-positive cases and autopsy algorithms for safely handling of suspicious bodies during this pandemic.
BACKGROUND/AIMS
The aim of this study is to share autopsy findings of COVID-19-positive cases and autopsy algorithms for safely handling of suspicious bodies during this pandemic.
METHODS
COVID-19-positive cases of Istanbul Morgue Department were retrospectively analyzed. Sampling indications for PCR tests in suspicious deaths, macroscopic and microscopic findings obtained in cases with positive PCR tests were evaluated.
RESULTS
In the morgue department, 345(25.8%) of overall 1336 autopsy cases were tested for COVID-19. PCR test was found positive in 26 cases. Limited autopsy procedure was performed in 7 cases, while the cause of death was determined by external examination in the remaining 19 cases. Male-to-female ratio was found 3.3:1 and mean age was 60.0 ± 13.6 among all PCR-positive cases. Cause of death was determined as viral pneumonia in fully autopsied cases. Most common findings were sticky gelatinous fluid in cavities and firm and swollen lungs, varying degrees of consolidation. In microscopy, diffuse alveolar epithelial damage, type-II pneumocyte hyperplasia, hyaline membrane formation, fibrinous exudate, and fibrinous plaques in the alveoli were the most common findings.
CONCLUSIONS
In COVID-19 autopsies, pulmonary findings were found to be prominent and the main pathology was pneumonia. Older age and findings of chronic diseases indicate that the cases were in the multirisk group in terms of COVID-19 mortality.

Review
Many articles on COVID19 deaths have been published since the pandemic has occurred. On reviewing the articles published until June 2021, the findings were very heterogeneous. Adding to the existing knowledge, there were also some unique observations made in the pathogenesis of COVID19. This review was done to determine the findings obtained and inferences drawn from various studies published globally among patients who died due to COVID19. PRISMA guidelines were used to conduct this systematic review. A search of databases like PubMed, ScienceDirect and Epistemonikos was done. The articles focusing on postmortem sample studies involving full autopsies, minimally invasive autopsies and tissue biopsy studies were screened and searched. The studies included were all the case reports, case series, narrative reviews and systematic reviews obtained in full text and in the English language containing study information, and samples obtained postmortem. The information obtained was tabulated using Microsoft excel sheets. The duplicates were removed at the beginning of the tabulation. Zotero referencing software was used for article sorting and citation and bibliography. Two authors independently reviewed the articles throughout the process to prevent bias. Adding to the heterogeneity of COVID19, the concept of lethality in preexisting disease conditions, the occurrence of secondary bacterial and fungal infections, and other pathogenetic mechanisms uniquely encountered are to be considered in treating the patients. Also, the presence of SARS-CoV-2 postmortem is established and should be considered a hazard.

Review
In order to create a three-dimensional (3D) documentation of findings which can be reassessed if necessary by other experts, the research project 'Virtopsy®' was launched in the late 1990s. This project combined autopsy results with forensic imaging in the form of computed tomography, magnetic resonance tomography and 3D surface scanning. The success of this project eventually succeeded in convincing the courts in Switzerland to accept these novel methods as evidence. As opposition towards autopsies has grown over the last decades, Virtopsy also strives to find and elaborate additional methods which can answer the main forensic questions without autopsy. These methods comprise post-mortem angiography for illustration of the vascular bed and image-guided tissue and fluid sampling for histological, toxicological and microbiological examinations. Based on the promising results, post-mortem imaging, especially with 3D surface scanning, has meanwhile also been applied to living victims of assault, who have suffered patterned injuries due to bites, blows with objects, etc. In our opinion, forensic imaging is an objective method which offers the possibility for a reassessment of the findings by other experts, even after burial or cremation of the corpse, or healing of the injuries in living victims, thus leading to a greater security in court.

Review
CONTEXT.—
The novel coronavirus disease 2019 (COVID-19) pandemic is significantly changing methodologic approaches in all branches of the health system. From a forensic point of view, this event is partly changing the manner in which forensic pathologists and all those who work in autopsy services operate, but above all, it is changing the patterns established for years by which cadavers are analyzed postmortem.
OBJECTIVE.—
To present a review of the literature and a proposal for COVID-19 autopsy protocols. To contain the infection risk, a revision of all the protocols that until now have been applied to the examination of bodies that require autopsy services is required.
DATA SOURCES.—
Currently, the diagnosis and postmortem analysis of positive or suspected COVID-19 cases plays a crucial role in scientific research. A review of the main recommendations proposed by international scientific societies regarding the risk of infection during autopsy was carried out. Scientific papers currently available via the PubMed NCBI search engine on COVID-19 postmortem diagnosis were also examined.
CONCLUSIONS.—
Throughout the history of medicine, autopsy has been fundamental to the understanding of multiple pathogenic processes that are investigated postmortem. The purpose of the study is to propose an operating protocol that can be useful for all clinical and forensic autopsies, with particular reference to the correct methods to be applied to the examination of positive or suspected COVID-19 cases, regarding both the autopsy procedure and the collection and analysis of biological samples.

Autopsy training is required for board certification by the American Board of Pathology and may be affected by autopsy rate. It is unclear whether the COVID-19 pandemic has affected autopsy education and rate. Prior to the pandemic, our autopsy gross organ review lectures at the Brown University pathology residency program were in-person and used a detective style to discover the pathological lesions followed by an integrated discussion of anatomic and clinical pathology. During the COVID-19 pandemic, these lectures became remote and there was a noticeable impact on the involvement and responsiveness of the audience compared to in-person teaching. Certain qualities of face-to-face teaching can be difficult to be reproduced through virtual teaching, including the detective style to look for pathological lesions and the ability to palpate lesions from gross specimens. Our results showed that the autopsy case number increased during the COVID-19 pandemic, but the overall autopsy rate did not significantly change.

Jornal de Pediatria 2022To evaluate neonatal autopsy rates at a tertiary hospital in southern Brazil ascertain the level of agreement between premortem and postmortem diagnosis.
OBJECTIVES
To evaluate neonatal autopsy rates at a tertiary hospital in southern Brazil ascertain the level of agreement between premortem and postmortem diagnosis.
METHODS
The authors reviewed all neonatal autopsies performed over a 10-year period and described the percentage of neonates who died and underwent autopsy. The authors tested for agreement between autopsy findings and the cause of death as defined by the neonatologist. Agreement between clinical diagnosis and autopsy findings was classified using the modified Goldman criteria. Additional findings at autopsy were grouped by organ system. Linear regression and multiple comparisons were used for statistical analyses.
RESULTS
During the study period, 382 neonates died at the Neonatal Intensive Care Unit (NICU). Consent to perform an autopsy was obtained for 73 (19.1%). The complete agreement between autopsy findings and the neonatologist's premortem diagnosis was found in 48 patients (65.8%). Additional findings were obtained at autopsy in 25 cases (34.2%). In 5 cases (6.9%), the autopsy findings contributed to subsequent genetic counseling. Seven autopsies (9.6%) revealed a diagnosis that would have changed patient management if established premortem. The autopsy rate increased by an average of 1.87% each year.
CONCLUSION
Despite a high level of agreement between clinical diagnosis and pathological findings, autopsies provided relevant data regarding the cause of death, providing additional clinical information to neonatologists and allowing genetic counseling of family members.

Review
BACKGROUND
Analyses for the presence of SARS-CoV‑2 in the tissues of COVID-19 patients is important in order to improve our understanding of the disease pathophysiology for interpretation of diagnostic histopathological findings in autopsies, biopsies, or surgical specimens and to assess the potential for occupational infectious hazard.
MATERIAL AND METHODS
In this review we identified 136 published studies in PubMed's curated literature database LitCovid on SARS-CoV‑2 detection methods in tissues and evaluated them regarding sources of error, specificity, and sensitivity of the methods, taking into account our own experience.
RESULTS
Currently, no sufficiently specific histomorphological alterations or diagnostic features for COVID-19 are known. Therefore, three approaches for SARS-CoV‑2 detection are used: RNA, proteins/antigens, or morphological detection by electron microscopy. In the preanalytical phase, the dominant source of error is tissue quality, especially the different intervals between sample collection and processing or fixation (and its duration) and specifically the interval between death and sample collection in autopsies. However, this information is found in less than half of the studies (e.g., in only 42% of autopsy studies). Our own experience and first studies prove the significantly higher sensitivity and specificity of RNA-based detection methods compared to antigen or protein detection by immunohistochemistry or immunofluorescence. Detection by electron microscopy is time consuming and difficult to interpret.
CONCLUSIONS
Different methods are available for the detection of SARS-CoV‑2 in tissue. Currently, RNA detection by RT-PCR is the method of choice. However, extensive validation studies and method harmonization are not available and are absolutely necessary.
