RESUMO
ABSTRACT: In Tunisia, hydatid cyst is an endemic parasitic disease. The cyst may remain asymptomatic, discovered accidentally, or in case of a complication, the most serious of which is sudden death. We propose, in this article, to analyze the degree of involvement of the cyst in the mechanism of death, through the review of 25 cases. A total of 7932 autopsy cases were performed during the study period. Twenty-five cases of hydatid cyst discovered at autopsy were collected and death was attributed to hydatid cyst in 13 cases. The seat of the cyst was variable and death was due to anaphylaxis in 10 cases, to hydatious embolism in 2 cases and to cardiac arrhythmia, resulting from a cardiac localization of a large hydatid cyst, in 1 case.Although rare, echinococcosis can be a life-threatening disease. Its involvement in the death mechanism remains difficult in many cases.

Chronic calcific constrictive pericarditis is a rare condition. It can cause severe morbidity and even mortality. The diagnosis may be difficult to establish due to its variable clinical signs. We report an autopsy case of a 54-year-old male with a past medical history of well treated hypertension, diabetes and dyspnea present of 2 weeks, who was discovered dead in his bed. The postmortem examination showed a large band of calcification of the pericardium with obliteration of the pericardial space. Both pericardium and epicardium were thickened with bread-and-butter appearance. Microscopic examination showed thickened pericadium which is formed by a fibrous paucicellular tissue containing extensive basophilic calcifications.

The spread of the disease of HIV has been decreased since the promotion and protection of human rights. In Tunisian law, patient infected by HIV, as every citizen, enjoys of all his rights without any discrimination, including the right to life and dignity, the right to care access, the free choice of doctor, the right to be informed and consent before any health care and specially the right to medical confidentiality. The Code of patients rights and the law no° 2007-12 of 12 February 2007 supplementing the law no° 92-71 of 27 July 1992 related to transmitted diseases ensure the protection and the respect of these rights. However, law requires a great sense of responsibility from patients and obliges them to avoid any unconscious behavior that can risk transmission of the disease. But, the application of these laws raises always many ethical problems that need reflexions.

Fibromuscular dysplasia of the coronary is an uncommon coronary defect with a range of pathological alterations and unpredictable clinical description that can cause sudden death. We present an autopsy case of sudden cardiac death due to a rupture of a coronary artery aneurysm in a 59-year-old woman. Postmortem autopsy revealed two huge saccular aneurysms located at the right coronary artery, one of which was ruptured leading to a fatal hemopericardium. Histopathological examination revealed coronary artery fibromuscular dysplasia with fibromyxoid dissociation of the media causing saccular aneurysms. The involvement of coronary arteries in fibromuscular dysplasia with aneurysmal features has been rarely reported in the literature and is most likely an underdiagnosed finding. Due to the little number of published studies, the etiology is not fully understood and data on pathogenesis, risk factors, manifestation, disease course, and mortality are still unclear, which is a gap that needs to be filled in order to avoid under-diagnosis of the disease. Our case report aimed to discuss the mechanisms of sudden death attributed to coronary fibromuscular dysplasia.

The mastoid bone, situated at the base of the skull and characterized by its compact structure in the petrous portion, being among the slowest-growing bones, has gained recognition as a valuable anthropological tool for sex determination. Thus, we have proposed to assess the reliability of the mastoid process in sex determination in a Tunisian population using CT-scan analysis. A cross-sectional study was conducted. CT scans forming the mastoid triangle were analyzed using a General Electric Bright Speed scanner. Nine measurements were taken by a single observer, ensuring reliability through intra- and inter-observer assessments. Normalization and statistical analyses, including logistic regression, were applied to identify sex-discriminating variables. The model's performance was evaluated using learning curves, cross-validation, and various metrics. The resulting logistic regression equation, coefficients, and intercept provided a predictive tool for sex determination. A total of 256 cranial CT scans (126 males, 130 females) were analyzed. Our study revealed that the mastoid region approach achieved an overall accuracy of 80.8 % in sex identification within the examined population. The method demonstrated a sensitivity of 78.9 % and specificity of 81.8 %. All investigated variables (AP, PM, AM, CMH, TMH, OSDmax, OCDmax, MA) exhibited discriminatory capabilities for sex determination, except for AIA. Notably, the most effective discriminators were AP, CMH, and OSDmax. Utilizing an ROC curve analysis to optimize mastoid variables for maximum sensitivity and specificity, we obtained excellent results, with an area under the curve reaching 91 %.
RESUMO
Since the 1950 s, several studies have reported that patients using first generation and/or second-generation antipsychotics had increased risk of venous thromboembolism events. These events include deep vein thrombosis and/or pulmonary embolism (PE). However, data about fatal PE in patients on antipsychotics (APs) remain scarce. Thus, the current study aimed to investigate sociodemographic, clinical and pharmacological characteristics related to psychiatric patients on APs and who died from a fatal PE. We reported a case-series, then conducted a literature review of relevant studies and performed a meta-analysis of studies with usable data. The main outcome of the study suggested a significantly high risk of fatal PE in patients using APs compared to nonusers (Odds Ratio=6.68, with 95% confidence interval 1.43-31.11). Clozapine was the most incriminated drug. Low potency first generation APs were the second most exhibited medication. Studies about the topic remain scarce with a high heterogeneity and a high probability of bias. Further studies are needed to ascertain this risk and to establish target preventive measures in this particularly vulnerable population.

Cirrhosis cardiomyopathy is defined by cardiac dysfunction in cirrhotic patients. It is characterized by the reduced contractile response to stress and/or impaired diastolic relaxation associated with electrophysiological disturbances with unknown cardiac disease. Here we report a case of sudden death in a 44-year-old woman, with no personal and family medical history and in apparently good health before death. The death was occurred when performing agricultural activities. The autopsy revealed an elevated weight of the heart with heterogeneous myocardium. The liver was heavy and had a variegated appearance. The histologic examination showed fibrosis and partially disturbance of the texture of the left ventricular myocardial tissue with storiform patterns and circumscribed hypertrophic cardiomyocytes. The microscopic examination of the liver showed cirrhosis with no specific features of etiology. The death was attributed to arrythmia due to cirrhotic cardiomyopathy. Our case highlighted the importance of pathological examination to con-sider the diagnosis of cirrhotic cardiomyopathy in case of sudden death for patient with known or unknown cirrhosis.

BACKGROUND: The common methods of suicide are hanging and poisoning. Suicidal electrocution using a homemade device is very rare. Victims usually possess knowledge of electrical circuits. Here, we report two cases of suicide by electrocution using a homemade device. CASE PRESENTATION: Case 1: A retired electrical technician was found unresponsive in his bedroom, with two bare copper wires; one encircling the index finger of the left hand, and the other placed in the mouth. The other ends of the wires were connected to a wall plug supplying 220 V current. Forensic autopsy and microscopic findings attributed death to suicidal electrocution.Case 2: A 51-year-old-man was found dead in the bathroom with bare copper wires encircling both wrists and connected to a wall plug carrying 220 V current. Death scene investigation, necropsy, histological tests and toxicological screening indicated suicide by electrocution.
RESUMO
Echinococcosis, also known as hydatid disease, is a common parasitic human infestation found in sheep-breeding areas. It is caused by the larvae stage of Echinococcus granulosus, and cysts develop mostly in the lungs and the liver. Cardiac involvement is unusual and silent until acute complications or a fatal outcome occurs. Herein, we report an autopsy case of a young healthy adult who died suddenly. The autopsy revealed an external bulging on the right heart ventricle outlet with a fluid-filled cystic cavity discovered on sectioning. Dissection of other organs did not reveal other cyst locations. Histological examination ascertained the diagnosis of hydatid cyst, and death was attributed to cardiac arrhythmias. Pathologists should keep in mind that hydatid cysts can develop anywhere in the body. Solitary cardiac cyst is rare and can simulate a "silent bomb". Unfortunately, sudden death remains the frequent manner of revelation of this disease in endemic areas.
RESUMO
Ventricular non-compaction (VNC) is a rare myocardium disorder, which can be both genetic and sporadic. A poor wall compaction process or an excessive trabeculae formation may be at the genesis of myocardial hypertrabeculation with multiple recesses. It is often complicated by ventricular dysfunction, arrhythmias and cardiac embolism. Herein we report a case of a 20-year-old male patient with no particular past medical history who was followed up at the cardiology department for dyspnea. Echocardiography showed reduced ejection fraction of the left ventricle with potential hypertrabeculation in the right ventricle, confirmed by cardiac MRI. The patient was not put under medication and was later lost to follow-up. He died few months later without a clear cause explaining death. A forensic autopsy was performed that attributed death to acute ventricle arrhythmia secondary to VNC, emphasizing the major role of an early and specific treatment to avoid such a fatal outcome.

Postobstructive pulmonary edema is a life-threatening complication that occurs after the removal of severe upper airway obstruction. Development of postobstructive pulmonary edema has been described after several cases of upper airway obstruction. However, postobstructive pulmonary edema developing after non-lethal hanging has not been reported widely in the literature. Herein, we describe a fatal case of postobstructive pulmonary edema in a 10-year-old girl, which was brought to the hospital with history of attempted suicide by hanging. At presentation, the girl was breathing laboriously. The oxygen saturation was of 82% and pulmonary auscultation revealed bilateral and diffuse crepitations. The chest computed tomographic scan showed bilateral diffuse infiltrates consistent with pulmonary edema. After 3 days of hospitalization, the respiratory state of the girl worsened leading to death despite intensive care. An autopsy was conducted and confirmed the diffuse pulmonary edema. Hence, this case confirms that delayed death in near hanging may occur. Pulmonary edema which develops subsequently in such patients is an uncommon mechanism of death that physicians should consider in emergency room.
RESUMO
The diagnosis of aortic dissection is often difficult because the symptoms are usually non-specific. AD should be considered in the differential diagnosis of all cases of idiopathic retrosternal pain. Misdiagnosis of AD is a common cause of legal suits in medical practice. Prevention requires a complete and thorough evaluation.
RESUMO
INTRODUCTION: Textiloma is a mass composed of retained surgical textile foreign body. It is a rare iatrogenic complication that can engage the doctor's responsibility. The aim of this manuscript is to report an unusual case of breast Textiloma mimicking a recurrent tumor and to highlight its medico-legal implications. PRESENTATION OF CASE: A 47-year-old lady, without past medical history, was diagnosed with a breast infiltring intraductal carcinoma. She was treated with mastectomy. Four years later, the patient consulted her surgeon for a subcutaneous mass in the operative site. Both medical and radiological investigations concluded to recurrent tumor. Histological examination confirmed the diagnosis of Textiloma. DISCUSSION: Retained foreign bodies in the operative site are infrequent but serious iatrogenic complications. Clinical manifestations of Textiloma are variable and non-specific. It should be suspected in any postoperative case with unresolved or unusual problems. It can mimic other conditions such as tumor. Textiloma is a frequently injurious situation that can lead to medico-legal implications. It is considered to be a sample of medical negligence that involves the surgeon responsibility. CONCLUSION: Textiloma is a preventable condition and it can be avoidable by maintaining standard recommendations.
