Corpse or not? Two peculiar cases of misidentification.

Irrespective of whether they are intended for collectors or for the fetish market, dolls are being produced to look more and more realistic with such a degree of life-like detail that they can be mistaken for a real person. This paper reports two cases of misidentification due to this increasing similarity: In the first case, a sex doll was mistaken for a corpse; in the second case, a corpse was mistaken for a doll. While in the latter case, only medical laypersons were at the discovery site, in the first case, an emergency doctor had issued a medical certificate of death for the purported corpse. The medicolegal examiner who was subsequently called to the scene could still rectify the misconception on-site. Mistakes of this nature are likely rare phenomena. It, however, remains to be seen if the increasingly life-like appearance of dolls on the one hand, and the increasingly doll-like appearance of some people, e.g., through cosmetic surgery, will lead to a rise in such cases. To avoid misidentification as in the first reported case, it is essential to prepare medical students well for the task of performing a primary external postmortem examination; it is equally important that fully-trained doctors regularly refresh their expertise in this respect.

Respiratory viruses in medicolegal autopsies during the winter season 2021/2022: observations after reduction of coronavirus disease-19 (COVID-19) pandemic restrictions.

In the context of the coronavirus disease (COVID-19) pandemic, measures were taken to protect the population from infection. These were almost completely lifted in several countries in the spring of 2022. To obtain an overview of the spectrum of respiratory viruses encountered in autoptical routine case work, and their infectivity, all autopsy cases at the Institute of Legal Medicine in Frankfurt/M. with flu-like symptoms (among others) were examined for at least 16 different viruses via multiplex PCR and cell culture. Out of 24 cases, 10 were virus-positive in PCR: specifically, 8 cases with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), 1 with respiratory syncytial virus (RSV), and 1 with SARS-CoV-2 and the human coronavirus OC43 (HCoV-OC43), as a double infection. The RSV infection and one of the SARS-CoV-2 infections were only detected due to the autopsy. Two SARS-CoV-2 cases (postmortem interval of 8 and 10 days, respectively) showed infectious virus in cell culture; the 6 other cases did not show infectious virus. In the RSV case, virus isolation by cell culture was unsuccessful (Ct value of 23.15 for PCR on cryoconserved lung tissue). HCoV-OC43 was measured as non-infectious in cell culture, with a Ct value of 29.57. The detection of RSV and HCoV-OC43 infections may shed light on the relevance of respiratory viruses other than SARS-CoV-2 in postmortem settings; however, further, more extensive studies are needed for a robust assessment of the hazard potential due to infectious postmortem fluids and tissues in medicolegal autopsy settings.

Aspiration-related pneumonia after Taser exposure - A multiple causations mechanism.

Arrest-related deaths in the context of Conducted Electrical Weapon (CEW) deployment are rare. The evaluation of such complex events is a challenge for the forensic scientist. We present a case of a 49-year old man, who was exposed to a Taser X26P during a confrontation with the police. He lost consciousness, vomited, aspirated and died after having been hospitalized for several days at the ICU. Based on the patient´s medical history, autopsy findings, witness testimonies, and reliable clinical and toxicological blood parameters, the most probable cause and mechanisms of his death are discussed. The present work demonstrates, based on one case report, the possibilities as well as limitations of forensic assessment in CEW-related deaths.

Detection and infectivity of SARS-CoV-2 in exhumated corpses.

Postmortem detection of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) after the exhumation of a corpse can become important, e.g. in the case of subsequent medical malpractice allegations. To date, data on possible detection periods [e.g. by reverse transcription polymerase chain reaction (RT-PCR)] or on the potential infectivity of the virus after an exhumation are rare. In the present study, these parameters were examined in two cases with a time span of approximately 4 months between day of death and exhumation. Using SARS-CoV-2 RT-PCR on swabs of both lungs and the oropharynx detection was possible with cycle threshold (Ct) values of about 30 despite signs of beginning decay. RT-PCR testing of perioral and perinasal swabs and swabs collected from the inside of the body bag, taken to estimate the risk of infection of those involved in the exhumation, was negative. Cell culture-based infectivity testing was negative for both, lung and oropharyngeal swabs. In one case, RT-PCR testing at the day of death of an oropharyngeal swab showed almost identical Ct values as postmortem testing of an oropharyngeal swab, impressively demonstrating the stability of viral RNA in the intact corpse. However, favorable climatic conditions in the grave have to be taken into account, as it was wintertime with constant low temperatures. Nevertheless, it was possible to demonstrate successful postmortem detection of SARS-CoV-2 infection following exhumation even after months in an earth grave.

Death abroad: Medico-legal autopsy results of repatriated corpses: A retrospective analysis of cases at the Department of Legal Medicine in Frankfurt am Main.

INTRODUCTION: Repatriated corpses may have been autopsied abroad. The aim of the study was to compare the findings from second medico-legal autopsies with those from primary autopsies abroad to spotlight possible implications for the management of repatriated corpses. MATERIAL AND METHODS: All autopsies from a 20-year period at the Institute of Legal Medicine in Frankfurt am Main on repatriated corpses of German citizens were reviewed. The results were compared with the information from the body passports, the protocols of the autopsies in the country of death, and the police files. RESULTS: In total, 151 corpses repatriated from 56 different countries were autopsied. The interval between death and autopsy in Germany was 2-603 days (median: 11 days). 91 of the repatriated corpses (59.5%) had previously been autopsied abroad. Three body cavities had been opened in 78.0% (71/91) of the original autopsies; among them, there were 11 cases (15.5%) with dissection of all organs, as opposed to 7 cases (9.9%) with all organs intact and in situ. Of the previously autopsied corpses, 62.6% were accompanied by a body passport that noted the cause of death. In nearly 75% of these cases, the stated cause of death was compatible with that established at second autopsy. In 5 cases (10.2%), the cause of death established in the second autopsy disagreed with that on the body passport. The most prominent disparity was a cranial gunshot wound rather than the stated fatal fall. DISCUSSION: This analysis of individual cases spotlights the problematics of an uncritical approval of the body passport. In light of the different procedural autopsy standards around the world, the validity of an autopsy abroad is discussed in the context of the second autopsy results. CONCLUSION: A second external postmortem examination by qualified medical practitioners should be obligatory in all cases of repatriated corpses, with notification of the criminal police in all cases of non-natural or undetermined death. A timely second autopsy is recommended even in cases with previous autopsy abroad.

Trisomy 21 in forensic autopsies: Review of a 20-year period.

BACKGROUND: Trisomy 21 is the most common human chromosomal abnormality. Its manifestation includes intellectual impairment and more or less typical anatomical malformations and functional deficiencies that can cause sudden or unexpected deaths. Typical medicolegal questions at autopsy are related to medical malpractice, improper care, neglect, or abuse, and, depending on the cause of death, whether the death might have been avoidable. The aim of this study was to examine whether the causes of death in individuals with trisomy 21 were linked to the known health risks for this condition and to consider how these deaths might have been prevented. MATERIAL AND METHODS: A retrospective study was performed at the Institutes for Legal Medicine in Giessen and Frankfurt am Main, Hesse, Germany. All records for forensic autopsy cases within a 20-year period from 1998 to 2017 were reviewed for the diagnosis trisomy 21", respectively, "Down's syndrome". RESULTS: Twenty-three cases complied with the inclusion criteria trisomy 21 and autopsy. The age of the deceased ranged from 23 days to 61 years. Infectious diseases, mainly respiratory, were the leading cause of death, followed by accidental deaths. CONCLUSION: The medicolegal relevance of the known health risks in Down's syndrome could be illustrated by the autopsy findings and the results of the additional examinations. The known high susceptibility to infections, with an increased risk of a rapid course and lethal outcome, in individuals with Down's syndrome could be confirmed in our study. A sound knowledge of the risks and abnormalities associated with trisomy 21 are helpful in medicolegal assessments, particularly, in relation to medical malpractice charges.
