RESUMO
AIMS: This study aims to better understand patterns of unintentional fatal drowning among children in North Tunisia. METHODS: A cross-sectional retrospective study including all unintentional fatal drowning among children was conducted in the Legal and Forensic Medicine department in the Charles Nicolle Hospital, Tunis, between January 2010 and December 2019. Socio-demographic variables, as well as death circumstances, were documented for each victim and analyzed. RESULTS: A total of 200 casualties were included in this study. The highest rate of deaths was observed in the summer (N=44). Most of the victims were males and 55.5% were aged between 13 and 18 years. The drowning occurred in a canal or the sea in 33.5 % and 29.5 % of the cases respectively. The distribution of drowning sites varied significantly by season and place of living: drowning in the sea was more likely to occur in the summer and in urban areas (p < 0.05). In the first years of life, drowning occurred mostly in buckets and wells (N=9 and N=10, respectively) while between 7 and 18 years, it was more frequent in a canal or the sea. Swimming was the leading activity before death in 50% of the cases. CONCLUSIONS: Unintentional fatal drowning among children remains an underestimated major health problem in Tunisia especially in the population aged from 7 to 18 years. Effective prevention measures should be implemented nationwide, especially around seas and canals.

OBJECTIVES: The aim of our study was to analyze the epidemiological characteristics for suicide methods and factors over a 12-year period among child suicides in Northern Tunisia and to compare juvenile and adolescent suicides. STUDY DESIGN: This is a cross-sectional study. METHODS: We included all child and adolescent suicide cases that took place in the North of Tunisia over a 12 year period (2005-2016). Data were collected from medical records and judicial inquiries and were classified into three sections: sociodemographic data, the circumstances of suicide, and the autopsy findings. Data were then compared between the 'juvenile suicide group' and 'the adolescent suicide group', according to the WHO definition. RESULTS: Casualties were equally males and females, mostly adolescents (74.5%), aged 15 years old on average. Hanging was the most frequent suicidal method. A peak of frequency was observed in 2014. CONCLUSION: Our results suggested to focus, among other preventive measures, on the role of media coverage of child suicides.

OBJECTIVE: To analyze the victims profile related to death among homeless people. STUDY DESIGN: A descriptive, retrospective, and cross-sectional study. METHODS: We included all deaths among homeless people that occurred during a 10-year period (2005-2014) that were autopsied in the Department of Legal Medicine of the Charles Nicolle Hospital of Tunis. Causes of death were classified according to the International Statistical Classification of Diseases and Related Health Problems 10th Revision. Data were classified in three sections: sociodemographic data, circumstances of death, and autopsy findings. A univariate data analysis was performed. RESULTS: The sex ratio (M/F) was of 7.45. The average age was of 59 years. The majority of deaths (80.9%) occurred in the metropolis of Tunis with a significant occurrence of cases in other governorates after the 2011 revolution (P = 0.002). Deaths occurred more often during winter (34.8%). The bodies were frequently discovered in public places (36.0%) and private locations (34.0%). The deaths of 55.3% of cases were attributed to natural causes, significantly affecting the elderly, whereas the accidental causes (25.7%) were more frequent before the age of 49 years, followed by suicides (3.9%) and homicides (3.3%). CONCLUSIONS: Our study highlighted a phenomenon not yet studied in Tunisia. Our results highlight an urgent need for preventive measures focused on the improvement of healthcare measures among homeless people.

Post-mortem changes in barbiturate concentrations were evidenced using a rat-secobarbital model. The method used for the extraction and HPLC assay of barbiturates is suitable for all biologic fluids and post-mortem tissues. Kinetic data obtained is of excellent quality. Various modelization constants were defined. This experimental work emphasizes the difficulty of post-mortem toxicology, as concentrations found at the time of autopsy may be different from concentrations at the time of death, in blood as well as in tissues.

PURPOSE: To develop profile of the victims and to study circumstances, causes of death and autopsy findings. METHODS: Retrospective study of cases of sudden death in sport activity whose autopsy was performed in forensic department of Tunis, between January 2005 and December 2009. RESULTS: During study period, 32 cases of SD in sport activity were recorded. These are amateur athletes predominantly male (84% of cases). Victims are aged between 15 and 79 years with an average age of about 33.16 years. Young subjects whose age is less than 35 years representing 68.7% of cases. 9.3% of victims had a family history of SD and 18.7% of cases had a known cardiac history. The sports most involved are running (40.6% of cases), football (31.3% of cases) and dance (12.5% of cases). Sixty-nine percent of victims died during sports activities. Presence of witnesses was noted in all cases; however, none of these witnesses has begun resuscitation. Cause of death was cardiac in 84.4% of cases. In young athletes, hypertrophic cardiomyopathy is the leading cause (nine cases), followed by arrhythmogenic right ventricular dysplasia (three cases). Among other causes, there is the myocardial bridge, congenital anomalies of the coronary arteries, aortic dissection and dilated cardiomyopathy. Beyond 35 years, coronary artery diseases represent the cause of death (nine cases). Only case of death secondary to non-cardiac disease occurred after a severe asthma attack. In four cases (12.5%), no cause of death was identified after a complete autopsy accompanied by further investigations. The cause of the death was imputed to a rhythmic pathology. CONCLUSION: This is the first study dealing with autopsy in SD in sport have provided a specific profile of victims. Other studies on larger samples and using standardized autopsy protocols are needed.

Atractylis gummifera is a poisonous plant widely found in North Africa. The thistle grows commonly in dry areas, and the juice of the rhizome is poisonous. It provokes frequent poisoning, especially of children. Toxic glucosides have been isolated and their identified as atractyloside and carboxyatractyloside. Tissues of high metabolic activity are the main target organs. Atractylis gummifera glucosides cause a severe hepatitis with fatal liver failure common. The plant's poisonous compounds interact with detoxication and/or transformation systems in the liver even at doses not likely to induce cytolysis by blocking ADP-ATP conversion through inhibition of P450 cytochrome. Clinical manifestations are related to an induced hypoglycemia and neurovegetative disorders or subsequent renal failure. Liver transplantation or immunotherapy may improve the often fatal prognosis.

To collect data on Tunisian herbal toxicity we analysed 56 medical records of patients admitted to the toxicological intensive care unit from 1983 to 1998 following the ingestion of plants. The sex ratio of patients was 1:2, the mean age of patients was 26y (2 to 75y) and II species of plants were involved with Atractylis gummifera (32%), Datura stramonium (25%), Ricinus communis (9%), Nerium oleander (7%) and Peganum harmala (7%) most commonly infested. Poisonings involved neurological (91%), gastrointestinal (73%) and cardiovascular systems (18%). Treatment was mainly symptomatic. The only lethal cases of liver failure involved 16 Atractylis gummifera poisonings.
