[Medical experimentation on prisoners (part 4): the dilemma of 'pros' and 'cons'.]

Given the long history of abuse of prisoners in medical experimentation, it is understandable that additional safeguards have been established to protect this social category. However, the debate between the detractors and the supporters of the medical experimentation in the prison environment is still going on. The present history note, the fourth in a series on medical experimentation on prisoners, intended to relate the main arguments of both sides: ie; the detractors and supporters of medical experimentation on prisoners.

Colorectal barotrauma following compressed air spray to the perineum.

Colorectal injuries caused by high-pressure air compressors are rare and reported especially among industrial workers. They may appear because of intended or accidental injury. In the present paper, we report a case of colorectal injuries due to air insufflation from a distance towards the anus with the clothes on, as a means of a practical joke. The patient presented one day after the trauma to the Emergency Department with complaints of severe abdominal pain and vomiting. On examination, he had signs of peritonitis. A computed tomography (CT) scan did not show any perforation. Emergency laparotomy was performed with the suspicion of pneumatic pressure-induced lesions. A total resection of the colon was made with enterostomy. The pathologic examination of the resected piece revealed multiple gangrenous areas without perforation associated to signs of peritonitis. Follow up was uneventful. A reversal of the enterostomy was scheduled.

Sudden death in the young adult: a Tunisian autopsy-based series.

BACKGROUND: We aim to study the profile, and pathological characteristics of sudden death in young in purpose of recommendations for prevention. METHODS: We performed a retrospective cohort study using autopsy data from the Department of Forensic Medicine of Monastir (Tunisia). A review of all autopsies performed for 28 years was done (August 1990 to December 2018). In each case, clinical information, and circumstances of death were obtained. A complete forensic autopsy and histological, and toxicological investigations were performed. We have included all sudden death in persons aged between 18 and 35 years. RESULTS: We collected 137 cases of sudden death during the studied period. The mean age of the studied population was 26.47 years. Almost 72% deaths were classified as cardiac death, and was due to ischemic heart disease in 32.32%. Sudden death was attributed to a pleuropulmonary cause in 7.4%, an abdominal cause in 6%, and from a neurological origin in 4.5%. The cause of sudden death in this group was not established by 9.5%. CONCLUSION: In this series, sudden death in young adults occurs mainly in a smoking male, aged between 18 and 24 years old, occurring at rest, in the morning, and early in the week. It is more common, especially in summer. Sudden death is most often the first manifestation of pathologies, especially unsuspected heart diseases. The predominance of cardiovascular causes is the common denominator of almost all studies reported in the literature. Our findings suggest that prevention of sudden death among young adults under the age of 35 years should also focus on evaluation for causes not associated with structural heart disease.

Sudden Death Due to a Cerebellopontine Angle Epidermoid Cyst: Case Report.

Epidermoid cyst of the brain is a rare benign embryonal tumor. It has an excellent prognosis because of its slow-growing nature. Clinically, symptoms are variable and depend on the location of the cyst. Sudden death may occur as a result of lethal complications because of the tumor growth, but it is still rare. In this article, we present a rare case of sudden unexpected death of a 58-year-old man, with no neurologic history, due to an epidermoid cyst of the brain diagnosed at autopsy.

Spontaneous Rupture of a Hepatic Cavernous Hemangioma: A Rare Case of Sudden Unexpected Death.

Cavernous hemangiomas represent the most common benign tumors affecting the liver. They are more often asymptomatic and usually diagnosed through radiological examinations performed for other reasons. When there are symptomatic, they may cause digestive disorders such as abdominal pain, nausea, vomiting, or a palpable mass. Sudden death may occur as a result of rupture and bleeding. Spontaneous rupture of cavernous hepatic hemangioma is a rare complication, but the mortality rate is high. We report a rare case of sudden unexpected death of a 46-year-old woman due to a spontaneous rupture of a giant hepatic cavernous hemangioma discovered at autopsy.
