Our objective was to observe the role of vascular endothelial growth factor (VEGF) 121 gene transfer in promoting vascular reconstruction and bone repair in femur head necrosis of rabbits. ⋯ VEGF might promote bone formation and revascularization in the subchondral necrotic region of the femoral head, indirectly protecting the necrotic bone trabecula from absorption and avoiding a reduction in the mechanical function of the subchondral region.

Chest tube insertion is an important component of medical and surgical education. This article reports a cost-effective and easily reproducible method for hands-on education of tube thoracostomy placement. ⋯ We have developed a simple, inexpensive training device for insertion of chest tubes and tested it on 134 military personnel.

To evaluate functional, radiologic, and subjective outcome after volar locking plate osteosynthesis (VLPO) for unstable distal radius fractures (DRF). ⋯ VLPO for the treatment of unstable DRF is a reliable technique with excellent subjective, objective, and radiologic outcome.

Injury is the leading cause of death for children older than 1 year. The incidence of childhood injury varies greatly depending on social factors, including income, family violence, and other social stressors. This study reports the incidence of injury among children aged 5 years in a cohort of vulnerable families. ⋯ Children in vulnerable families are at higher risk for injury. The incidence of 12.3% found in this cohort is substantially higher than CDC risk for 5-year-old children, that is, overall 9.3%. This longitudinal cohort has demonstrated a persistently elevated risk of childhood injury, but risk factors for injury have changed with age. As these children reached school age, low household income and male gender were risk factors for injury. This suggests that recognition of gender differences and targeted interventions for caregivers and play environments may be useful.

Advanced hemostatic dressings perform superior to standard gauze (SG) in animal hemorrhage models but require 2 minutes to 5 minutes application time, which is not feasible on the battlefield. ⋯ Advanced hemostatic dressings do not perform better than conventional gauze in an injury and application model similar to a care under fire scenario.
