Fatal rupture of hepatic adenomatosis: Autopsy case and review of the literature

Hepatic adenomatosis is a rare disease consisting of multiple adenomas in otherwise-normal liver parenchyma. Though the discovery of this entity goes back several years, its diagnosis is still challenging in terms of its definition and pathophysiology. Clinically, patients may be completely asymptomatic and the diagnosis is only made incidentally through imaging tests. The discovery could be made when complications occur such as intraperitoneal hemorrhage with hypovolemic shock due to the rupture of an adenoma. We report a fatal case of a ruptured adenoma in a case of hepatic adenomatosis discovered at autopsy. In order to achieve a better view of this disease, we conducted a literature review on this subject describing the pathogenesis, manifestations, and autopsy contribution to addressing this entity.

Cardiac rupture during acute myocardial infarction : Autopsy study (2004-2020)

INTRODUCTION

Cardiac rupture is a rare but critical complication of myocardial infarction with an incidence of 1 to 3% of cases. We aimed in this autopsy study to analyze the anatomical, epidemiological, cardiac, and coronary profiles of cardiac rupture in the Monastir region.

METHODS

We conducted a descriptive study with retrospective data collection of all cases of myocardial infarction complicated by a cardiac rupture over seventeen years (2004-2020).

RESULTS

Thirty-one cases were included in this study. The mean age of the cases was 67 years with a male predominance. Sixteen cases (57%) had cardiovascular risk factors. The most common symptomatology reported before death was acute chest pain in 57% of cases. Fourteen cases (45%) corresponded to the definition of sudden cardiac death. At autopsy, the heart had a mean weight of 452.78 grams. A large hemopericardium was associated in 90% of cases. Myocardial rupture involved the posterior wall of the left ventricle in 50% of cases. The myocardial rupture occurred at a site of acute myocardial infarction in 86% of cases and on a myocardial scar in 14% of cases. The coronary study showed double or triple vessel atherosclerotic coronary artery disease in 57% of cases with fresh thrombi at the infarct-related coronary in 11% of cases.

CONCLUSIONS

Our analysis found that cardiac rupture mostly involved elderly subjects with underlying cardiovascular risk factors. Our findings sustain that age is a determining prognostic factor after acute coronary syndrome with the need for further education and awareness-raising efforts to speed up access to care for these patients.

Patterns of Unnatural Deaths Among Children and Adolescents: Autopsy Study (2011-2018)

BACKGROUND AND AIMS

The problem of unnatural death in children is still relevant because of their vulnerability. This work aimed to describe the epidemiological profile and patterns of these medicolegal deaths in children and adolescents in northern Tunisia.

METHODS

We conducted a retrospective study from January 2011 to December 2018, within the Forensic Department of Charles Nicolle Hospital in Tunis. All children who died of unnatural causes were included (767 cases).

RESULTS

An overall male predominance was observed (sex ratio = 2.4). Accidental deaths represent the most common manner of death (81.4%) involving most frequently domestic accidents occurring in children aged between 1 and 4 years. In cases of suicide, the highest risk profile was a female child aged between 15 and 18 years. The suicide occurred most often in the victim's home with hanging representing the common means of suicide. For the criminal form, the most common means in those cases were stabbing and blunt injuries.

CONCLUSION

Our study delivered a broad picture of unnatural deaths among children in Tunisia. These deaths, largely absent from child survival initiatives presently on the global agenda, can be prevented if they are addressed strategically, as their injury prevention strategies differ from adults.

Death by late presenting of diaphragmatic hernia in an infant: case report and review of the literature

Background

Congenital diaphragmatic hernia (CDH) is a congenital malformation of the diaphragm, resulting in the herniation of the abdominal organs into the thoracic cavity. If not properly diagnosed before or at birth, CDH represents a life-threatening pathology in infants and a major cause of death. We present a fatal case of congenital diaphragmatic hernia corresponding to Bochdalek hernia, discovered incidentally during a sudden death’s autopsy of an infant. To achieve a better view of the range of these anomalies, we also conducted a literature review on this subject describing the pathogenesis, manifestations, diagnosis, and autopsy contribution to addressing these CDH.

Case presentation

The case involved a 4-month-old female infant who presented sudden respiratory difficulties after breastfeeding. External examination found marked cyanosis with no evidence of trauma. Upon opening the chest cavity, the stomach, markedly distended, was occupying much of the left pleural cavity. The left lung was compressed and displaced superiorly, and the heart was also compressed and deviated to the right. This mediastinal deviation was due to an ascension of the stomach into the chest cavity through a 2 × 1.5 cm defect in the posterior left hemidiaphragm. Further examination remarked an ecchymotic appearance of the stomach portion entrapped in the hernia defect suggesting recent strangulation of the stomach. The lungs showed atelectasis with signs of pulmonary infection in the histology study.

Conclusions

CDH might be considered uncommon and not always mentioned in the list of sudden death in infant causes. Forensic pathologists should know of this malformation in order to apply the best autopsy techniques and thus allow positive feedback to pediatricians considering the possible legal implications.

Imported malaria in adults: about a case of cerebral malaria

Background

Malaria is the first parasitic infection endemic in the world caused by parasites species of Plasmodium. Cerebral malaria (CM) is a rapidly progressive and severe form of Plasmodium falciparum infection, characterized by a greater accumulation of red blood cells parasitized by Plasmodium falciparum in the brain. The diagnosis of malaria is usually made in living patients from a blood sample taken in the course of a fever on return from an endemic country, whereas CM, often associated with fatal outcomes even in treated subjects, is usually diagnosed at autopsy.

Case presentation

We present the case of a 36-year-old man who died a few days after returning from a business trip to the Ivory Coast. As a result of an unclear cause of death, a medicolegal autopsy was ordered. Autopsy findings revealed massive congestion and edema of the brain with no other macroscopic abnormalities at organ gross examination. Histology and laboratory tests were conducted revealing a Plasmodium falciparum infection, with numerous parasitized erythrocytes containing dots of hemozoin pigment (malaria pigment) in all examined brain sections and all other organs. Death was attributed to cerebral malaria with multiple organ failure.

Conclusions

This report summarizes several features for the diagnosis of malaria and how postmortem investigations, as well as histology and laboratory diagnosis, may lead to a retrospective diagnosis of a fatal complicated form with cerebral involvement.

Sudden death related to the gastrointestinal system in Tunisia: A 13 year autopsy study

Sudden gastrointestinal (GI) death is an unexpected death due to digestive system causes mainly found after autopsy. The literature is rich in articles that studied sudden death due to cardiac causes while sudden GI deaths remain less well-documented. We retrospectively investigated all cases of gastrointestinal death at the Department of Forensic Medicine in Tunis, over 13 years (January 1, 2006 to December 31, 2018). Two hundred and eight cases were collected. The mean age of our series was 51.06 ± 20.99 years. No history of digestive disorders was reported in 78.4%, and no family history of sudden death was found in any cases. A male predominance was found in most epidemiological characteristics of the sample with a significant statistical rate in some features. Non-specific abdominal pain was the most described symptom (n = 92). Perforation of GI tract was the common mechanism involved in the death of 55 cases, of which 44 were related to ulcer perforation. These ulcer perforations were statistically more reported in smokers and people suffering from schizophrenia. Intestinal obstruction was the second commonest cause of death, mainly found in the elderly. Sudden death in children was most frequently caused by acute intussusception. This study highlights that systematic study of sudden death due to GI causes might provide opportunities to identify avenues for overall health improvement.

Criminal death by stabbing in the region of Kairouan, Tunisia: A retrospective study, 2008-2018

INTRODUCTION

Homicides by stabbing are the most common forensic form of criminal death in Tunisia. These homicides represent a type of violent death that requires investigation in a forensic setting.

AIM

To describe the epidemiological and forensic profile of stab wounds in the region of Kairouan, Tunisia Methods: We conducted a retrospective study of stab-wounds autopsy cases collected at the Forensic Department at the Ibn El Jazzar University Hospital in Kairouan over eleven years (01/01/2008 to 31/12/2018).

RESULTS

Forty-seven cases of homicide were retained. A male predominance was observed with a sex ratio of 22 (45H/2F, 96%). The mean age of the victims was 33.3±10.84 with ages ranging from 12 to 63 years. Most victims (79%) were of rural origin, singles (62%), and daily-laborers (89%). The months that recorded the highest numbers of homicides were November and August. The most common reason for the assault was a settling-score on the street. The perpetrator was known by the victim in 90% of cases, having used a knife as a weapon in 90% of cases. The thorax was the most frequently affected area, resulting in fatal heart wounds in 28 cases.

CONCLUSION

Autopsy remains an essential tool for drawing up a detailed injury assessment in homicides by stabbing and determining the injury mechanism of the wounds. The comparison of the autopsy findings with the data of the judicial investigation is of great help in the legal qualification of the facts and the determination of the responsibility of the aggressors.

Fatal coronary ectasia: An autopsy case report and review of literature

Coronary ectasia is a rare vessel defect that represents a pathological and incidental finding in routine coronary angiography performed for other coronary syndromes. This defect exposes to the risk of intra-coronary thrombosis by blood stasis due to the turbulent blood flow in those dilated areas that can lead to sudden death. We report an autopsy case of a male subject suddenly deceased. A medico-legal autopsy concluded an ischemic heart failure due to a vascular thrombosis by a blood clot in a coronary ectasia. Our case report aimed to discuss the mechanisms of sudden death attributed to coronary artery ectasia.

How to establish a medico-legal obstacle on the Medical Certificate of Death

Indicating a medico-legal obstacle to burial is not always evident for the pratician. In the absence of specific legal references and scientific Tunisian guidelines, we propose in this paper a practical guide to orientate the pratician on when and how to establish a medico-legal obstacle on the Medical Certificate of Death.

Evaluation médico-légale des certificats médicaux initiaux

Le certificat médical initial est un document médico-légal descriptif dont finalité est de prouver l´existence du dommage et de permettre à la victime d´obtenir ce que de droit. L´objectif de notre étude était d'étudier le contenu et d'évaluer la qualité de rédaction des certificats médicaux initiaux. Il s´agissait d´une étude rétrospective et descriptive sur une période de 18 mois allant de janvier 2015 à juin 2016. Nous avons colligé 450 certificats médicaux initiaux parvenus au service de médecine légale du centre hospitalier universitaire de Charles Nicolle à Tunis. La qualité des certificats médicaux initiaux a été évaluée grâce à un canevas qui a permis de leur attribuer une note sur 30. Les certificats médicaux initiaux évalués étaient majoritairement moyens. Les scores obtenus à partir du canevas que nous avons élaboré oscillaient entre 9,5 et 27,5/30 avec une moyenne de 18,59/30. Les médecins généralistes, les médecins ayant une spécialité d´organe comme les ophtalmologistes ou encore les neurochirurgiens et les médecins qui ont utilisé le support du ministère de la santé ont rédigé de meilleurs certificats. De même nous avons noté une qualité de rédaction meilleure lorsqu´il s´agit de coups et blessures volontaires. Notre étude a montré que la majorité des certificats médicaux initiaux ne sont pas conformes aux recommandations de rédaction. Ces insuffisances sont probablement liées au fait que les médecins n´ont jamais bénéficié d´une formation médico-légale adéquate.

Deadly falls into wells: A retrospective study of 72 autopsy cases from Kairouan, Tunisia

Falls are a traumatic event that represents a major public health problem worldwide. The literature is rich in published studies of falls from heights, but only a few articles have focused on falls into wells. The region of Kairouan, in central Tunisia, is characterized by an arid climate, hence the abundance of wells for watering crops. In this study, 72 cases of deadly falls into wells were retrospectively investigated at the Department of Forensic Medicine in Kairouan over eight years (01/01/2008 to 31/12/2015). A male predominance was found (sex ratio of 2.42), with a mean age of 29 ± 16.1 years. Sixty-five cases (90.3%) were from rural areas, 62.5% had a low level of education, and 50% were unemployed. In our series, the deceased fell from a distance between 3 and 70 meters with an average of 28.3 m. The falls occurred into functional wells in 61.1%, which were filled with water in 51.4%, and were unprotected in 88.9%. Autopsy findings showed bone fractures in 51.4% of cases of which 44.4% were rib fractures. Visceral injuries were identified in 55.6% of cases. The predominant manner of death was suicide (73.2%), and severe polytrauma was the most frequent cause of death (52.8%). This study highlights the need for increased safety measures to keep wells covered and protected in order to prevent these falls.
