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., (© 2021 American Academy of Forensic Sciences.)

Data about homicidal burns remain scarce. Intentional burns are a challenging situation in the case of an individual found dead in a fire zone with no witness of the fatal act. This study aimed to analyze the victim profiles of homicidal burns in Northern Tunisia. It was a descriptive cross-sectional study with a retrospective data collection over 15 years (January 2005-December 2019). In total, 60 cases of homicidal burns were collected. The mean age was 40.22 ± 18.1 years (range 4-82 years). We noted a male predominance (sex ratio M/F = 1.3). Most of the victims were married (48.3%), unemployed (40%), and living in an urban area (63.3%). Homicidal burns occurred most frequently in private homes for female victims (80.8%) and in public places for male victims (31.4%) (p < 0.001). The reported motive varied according to the victim's sex; males were mostly assaulted by an acquaintance in an interpersonal conflict (47.1%), and females were mostly assaulted by an intimate partner while in a dispute (42.3%; p = 0.001). The median total body surface area (TBSA) that was burned was 60.4%, and burn injuries were observed mainly in the anterior part of the body. In 19 cases, the burns were associated with another type of trauma, from which the most common association was burning and stab wounds (12 cases). The identified pattern of homicidal burn casualties was similar to the reported data in Western countries and to homicides in general in Tunisia, suggesting that prevention measures should address those of intentional interpersonal violence., (© 2021 American Academy of Forensic Sciences.)

Human ecchinococcosis also known as hydatid disease is a zoonotic infection caused by the tapeworm Ecchinococcus with 2-3 Million cases worldwide. We hereby report a 6 years period study of Sudden death due to hydatidosis aiming to analyze the epidemiological criteria, death circumstances, and autopsy observations attributed to hydatid disease. During the past 6 years, 26 death cases were due to hydatid disease. Our analysis shows that the sex ratio (M/F) was 1.6, the mean age was 31-year old, and 65% of the subjects lived in rural places. In 17 cases, death occurred in the victim's place, five victims died after a heavy exercise, and in two cases, death occurred immediately after trauma. At autopsy, 91% of the cysts were found in the liver. In three cases, death followed a septic state, and in two cases, it followed an acute respiratory failure. Death was attributed to anaphylaxis in 17 cases., (© 2013 American Academy of Forensic Sciences.)
