Purpose of the study. Revealing the features of the formation of damage to the structure of the chest and abdominal organs in pedestrians during their collisions with moving cars. Materials and methods. A forensic medical examination of 215 corpses of persons killed in collisions with moving cars was carried out. Among the dead there were 173 men and 42 women. The victims were between 14 and 75 years old. Research results and their discussion. It was found that among pedestrians who died in collisions with cars, injuries of two or more parts of the body with fractures of the limb bones (55.8%) and сombined injury (CI) of the head, chest, abdomen (23.3%) prevail. In the composition of CI, damage to the structure of the chest and organs of the chest cavity was noted in 85.6% of cases. Rib fractures were detected in 57.7% of cases; fractures in the midclavicular and axillary lines predominated in localization. Damage to the structure of organs and tissues of the abdominal cavity in the composition of the abdominal CI in pedestrians was -71.0%. At the same time, 80.8% of the dead pedestrians show signs of injury to organs and tissues with pronounced hemorrhages in the suspension apparatuses, walls and parenchyma of organs. In 23.2% of cases, along with hemorrhages, there is a violation of the anatomical integrity of organs, mainly the liver and spleen. The outlined nature of damage to the structure of the chest, organs of the chest and abdominal cavity made it possible to establish the possibility of their formation in the 3rd phase of car injury - the fall of the injured on the road surface. Traumatic (pleuropulmonary), hemorrhagic shock and hemorrhagic pneumothorax were the main causes of injuries at the prehospital stage.

Background: Carbon monoxide (CO) poisoning is the leading cause of death from poisoning (accidental and intentional). The number of cases of CO poisoning is increasing day by day. Aims: The aim of the study was to analyze the epidemiological situation of CO poisoning and identify the urgent aspects of this problem. In the article, the author provided a retrospective analysis of 117 cases of CO poisoning, registered in a number of regional branches of the Republican Scientific and Practical Center of the Forensic Medical Examination of Uzbekistan, after he studied and analyzed the world literature on the epidemiology of CO poisoning. It has been revealed that fatal poisoning ranks third after mechanical injuries and mechanical asphyxia and constitutes 6.3% (513 cases) in the range of deaths by violence (8078 cases). Therefore, CO poisoning is considered as one of the most prevailing (51%) causes of mortality. Conclusion: This is a global problem, with young males at risk. Further studies on the current clinical and forensic aspects of CO poisoning are required, and the necessity for regular analysis of epidemiological data for taking comprehensive measures to prevent CO poisoning is emphasized.

Background. Vertebral-spinal injuries (VSIs) account for 6.326% of skeletal injuries. However, despite the relevance of VSIs in all branches of medicine, the forensic aspects of this injury are insufficiently assessed. Material and methods. The study included three groups: people who died following multiple injuries from falling from a height (82 cases); those who died following collision with moving cars (172 cases); and drivers of passenger cars who died in road accidents (61 cases). Results. The article describes in detail the results of the analysis. As part of combined injury during falls, VSI was observed in 41.5% of cases with lesions of other body parts and often covering 2 or more parts of the spine, and in terms of localization, most often in the lower neck, upper chest, and lumbar regions. Compression fractures were often noted, which resulted from falls on the legs and buttocks. In pedestrians who were injured in collisions with cars, VSI was noted in 25% cases; of these, most cases involved distraction and rotational fractures of the vertebral bodies, with detachments at the level of vertebral fractures prevailing primarily with mainly trauma of the posterior processes. Injuries to the spine structure often included cervical -occipital trauma and damage to the cervical region, as well as combined injuries to the cervical-thoracic regions; VSI in affected drivers was noted in 14.5% cases and was characterized by cervical-occipital trauma as well as lesions of the cervical, upper thoracic, and lumbar vertebrae. Сonclusion: The revealed nature of damage to the noted structures should be taken into account in the process of forensic medical diagnosis and differential diagnosis of blunt injuries, especially in conditions of non-obviousness of the circumstances of the damage. The nature, volume and localization of injuries arising from these types of blunt mechanical trauma can be important in the process of organizing and providing medical care to victims at various stages of treatment, and information on the circumstances of the origin of injuries can become the basis for developing preventive measures to prevent injuries.
