Objective: Trauma in India is an increasingly significant problem, particularly in light of rapid development and increasing motorization. Social changes are resulting in alterations in the epidemiology of trauma. The aim of the study was to assess the various epidemiological parameters that influence the cause of injury in the patients admitted to a major trauma centre in northem India. Methods: An observational study of 748 patients chosen by random assortment was carried out over a peri- od of 1 year (August 2008 to July 2009). Age, sex, injury type and pattern were noted. Injury mode of upper and lower limbs was also noted. Results: Injuries occur predominately in the age group of 15-30 years. Males incurred more injury with male to female ratio of 6:1. The most vulnerable group was motorcycle users. Among the injured, farmers were the most commonly involved. Blunt injuries (94.92%) were much more common than penetrating injuries. Among patients with head injury, two wheelers related accidents were the most common (40.3%). Most spinal cord injuries were caused by falls from height (51.09%). Most lower limb fractures were simple type. Compound fractures of the lower limb were more common than up- per limb fractures. Conclusion: Strict enforcement of traffic rules, combined with improved infrastructure and behavior change can decrease the burden of road traffic accidents in India and other developing countries. This study could assist in raising the profile of road traffic accidents as a public health problem which needs to be addressed as a preventable cause of mortality and morbidity, and plan- ning appropriate interventions for this major challenge. Preventive strategies should be made on the basis of these epidemiological trends. 展开更多

Objective: Although long bone fracture in children is not life-threatening, it may cause major disability, loss of working days and severe psychological distress. We conducted this study to determine the pattern of extremity fracture due to trauma in children. Methods: During one year in six general hospitals in Tehran, trauma patients who were hospitalized for more than 24 hours and sustained injuries within seven days before admission were included in the study. The records of children (≤16 years old) hospitalized in six general hospitals in Tehran due to trauma were reviewed prospectively. Results: During the study period, 1 274 children had sustained extremity fractures. Male to female ratio was 3.6/ 1, with the mean age of (10.3±4.2) years. Falls and traffic crashes were the main causes of injuries, with the percentages of 57.3 % and 37.1%, respectively. Simple fall (falling on the ground) consisted 60% of patients that sustained fall-related injuries. Pedestrians and bicycle riders comprised most of the cases that were injured due to traffic crashes. Of our cases, 56.8% sustained fractures in the upper extremities and 43.2% in the lower extremities. Forearm was the most common fracture site (34.1%). Comparing our results in preschool and school-age children, falls were the main cause of injuries in both groups, but fractures of lower extremities were significantly more common in preschool children. Conclusions: Improvement of physical condition of sidewalks and crossings in roads will be necessary for prevention of injuries. More attention to safety of home environment should be paid for control of preschools' injury at home. Education of children and adults is necessary to reduce injuries resulting from road traffic crashes. 展开更多
