Background: Pesticide poisoning is recognized as an important public health problem worldwide, especially in the developing countries, such as Tunisia, where these products are massively used in agriculture. The objective of our study was to document the forensic deaths caused by pesticides reported from a forensic center located in the coastal region of Tunisia. Methods: This is a 19-year retrospective descriptive study of lethal pesticide poisoning victims autopsied in the

Background Fatal blast injuries are generally reported as a consequence of explosions, mainly in terrorist events, work-related detonations, or domestic settings. Although quite rare, blast injuries of high kinetic energy can be seen in tyre blowouts and are very dangerous and potentially lethal because of their unpredictability. This phenomenon is rarely reported in the existing forensic literature. The aim of this study was to report two cases of fatal truck tyre bursts and to discuss the mechanisms leading to the burst and the pattern of injuries. Case presentations Case 1 was of a 58-year-old truck driver man who was standing nearby a detached tyre that was being inflated in a repair shop when the burst occurred. The tyre struck him in the face and threw him. The medicolegal autopsy showed a right periorbital haematoma, a large wound of the left parietal scalp, a diffuse subarachnoid haemorrhage, an atlanto-occipital dislocation, a fracture of the hyoid bone, multiple rib fractures, and lacerations of the ascending aorta and the pulmonary arteries. Case 2 involved a young man of 24-year-old, a worker in a tyre repair shop, who was inflating a truck’s tyre when it burst violently. The injuries sustained included bleeding from the right ear, fractures of the facial bones, a left hemispheric subdural haematoma associated with the fracture of the skull base, a rib fracture, and diffuse areas of contusions to the lungs. Toxicological analyses were negative in both cases. Conclusion Fatalities related to tyre blowout accidents are uncommon. The mechanisms leading to a blowout can be mechanical or chemical in origin, and the main danger of a burst often occurs when air enters the tyre during inflation. Internal damage caused by the pressure waves of the blast often exceeds what would be expected based on external signs alone.

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.
