Background / Aim. In road traffic accidents, chest injuries are a critical factor since death usually occurs as a result of injuries to the heart and lungs, flail chest, pneumothorax, exsanguination etc. The aim of this study was to analyse the most vulnerable subjects in road accidents, as well as the most frequent and most significant types of chest injuries sustained by different categories of subjects, and to examine the relevance of certain injuries or risk factors to outliving the injuries. Methods. The autopsy, retrospective and cross-sectional study was performed at the Clinical Centre of Kragujevac, Department of Forensic Medicine and Toxicology. The study included all the participants in road traffic accidents on the territory of Kragujevac and the surrounding area who died from the injuries sustained or due to complications of the injuries during the period from 2001 to 2016. The subjects were divided into the following groups: pedestrians, motor vehicle drivers, front-seat passengers, back-seat passengers, bicyclists, motorcyclists and tractor drivers. Occurrence of injuries in three regions of the body (chest, head and abdomen) was analysed in all the subjects. Results. The study included 525 subjects who died due to injuries sustained in traffic accidents, which makes up for 38.4% of the total number of 1,366 autopsy cases covered by the study period. The average age of the subjects was 52±19 years. The study sample consisted of 391 (74.5%) men and 134 (25.5%) women. The most vulnerable subjects were pedestrians (220, i.e. 41.9%), followed by motor vehicle drivers (98, i.e. 18.7%), front-seat passengers (79, i.e. 15%), motorcyclists (39, i.e. 7.4%), bicyclists (38, i.e. 7.2%), back-seat passengers (29, i.e. 5.5%) and tractor drivers (22, i.e. 4.2%). Chest injuries were identified in 408 subjects (77.7%), while the most frequent type of injury was rib fracture, observed in two thirds of the sample. Out of the total number, 291 (55.4%) subjects died at the scene of the accident or on their way to the hospital, while 234 (44.6%) of them outlived injuries for a certain period of time. Drivers exhibited the highest risk of dying at the scene, while bicyclists outlived their injuries more frequently. Conclusion. Chest injuries are very common in subjects who died at the scene of road traffic accident.

Introduction: Some contributory factors are commonly known. If a person suffers from dizziness, for example, they will be more likely to lose balance and fall, which, in turn, leads to trauma. The influence of alcohol consumption on the incidence of injury has also been well documented in numerous studies. Other relevant factors, however, have received various assessments and recognition by different researchers. There is some disagreement among scientists concerning obesity. The aim of the thesis was to determine the influence of various factors on the incidence of injury. Materials and methods:The subjects used for the study were 800 patients receiving emergency treatment in the emergency department and hospitalised in the Department of Orthopaedics, Traumatology and Locomotor Oncology, Pomeranian Medical University in Szczecin (in Poland). The diagnostic survey method was employed. Results: Within the study group women were found to have a higher incidence of contusion. During a snowfall they also proved to suffer physical trauma more often than men. Men, on the other hand, displayed a higher incidence of injury at work. They were also more likely to suffer from torso injury. Younger individuals were more tired at the time of the accident than their older counterparts. Those having more sleep suffered fewer bone fractures. Conclusions: 1. The research showed that the group with the highest risk of trauma were women aged above 46 and suffering from hypertension. In contrast, for men the risk was highest among working individuals aged under 30. 2. Those with the highest incidence of injury were married couples with two children, having higher or vocational education, not working, living in towns with populations of over 200,000 and having a monthly income between 1000-2000 PLN per family member. 3. External factors like weather had the most significant impact on the incidence of injury sustained in motor vehicle accidents.

With the prevalence of diabetes, it is becoming important to analyze the diabetic wound age in forensic practice. The present study investigated the time-dependent expression of receptor for advanced glycation end products (RAGE) during diabetic wound healing in mice and its applicability to wound age determination by immunohistochemistry, double immunofluorescence, and Western blotting. After an incision was created in genetically diabetic db/db mice and control mice, mice were killed at posttraumatic intervals ranging from 6 h to 14 days, followed by the sampling of wound margin. Compared with control mice, diabetic mice showed the delayed wound healing. In control and diabetic wound specimens, RAGE immunoreactivity was observed in a small number of polymorphonuclear cells (PMNs), a number of macrophages, and fibroblasts. Morphometrically, the positive ratios of RAGE in macrophages or fibroblasts considerably increased in diabetic wounds during late repair, which exceeded 60% at 7 and 10 days post-injury. There were no control wound specimens to show a ratio of >60% in macrophages or fibroblasts. By Western blotting analysis, the ratios of RAGE to GAPDH were >1.4 in all diabetic wound samples from 7 to 10 days post-injury, which were >1.8 at 10 days after injury. By comparison, no control wound specimens indicated a ratio of >1.4. In conclusion, the expression of RAGE is upregulated and temporally distributed in macrophages and fibroblasts during diabetic wound healing, which might be closely involved in prolonged inflammation and deficient healing. Moreover, RAGE is promising as a useful marker for diabetic wound age determination.
