Firearms are a major cause of injury and death. We sought to determine (1) the prevalence of movie scenes that depicted firearms and verbal firearm safety messages; (2) the context and health outcomes in firearm scenes; and (3) the association between the Motion Picture Association of America ratings and firearm scene characteristics. ⋯ Depictions of firearms in top revenue-grossing movies were common, but safety messages were exceedingly rare. Major motion pictures present an under-used opportunity for education about firearm safety.

Our goal was to evaluate the utility of the pelvic ring stability examination for detection of mechanically unstable pelvic fractures in blunt trauma patients. ⋯ The presence of either pelvic deformity or unstable pelvic ring on physical examination has poor sensitivity for detection of mechanically unstable pelvic fractures in blunt trauma patients. Our study suggests that blunt trauma patients with Glasgow Coma Scale >13 and without pelvic pain or tenderness are unlikely to suffer an unstable pelvic fracture. A prospective study is needed to determine whether a set of clinical criteria can safely detect or exclude the presence of an unstable pelvic fracture.

The management of high-grade liver injuries often involves a combination of operative and nonoperative strategies. Angioembolization (AE) is frequently used in the management of these injuries. Morbidity in patients with high-grade hepatic injuries remains high despite improvements in mortality with a multimodality approach. Major hepatic necrosis (MHN) is a morbid, but underappreciated complication of AE in this patient population. This study will examine the risk factors and outcomes of patients with high-grade liver injures managed with AE who developed the complication of MHN. ⋯ High-grade liver injuries pose significant challenges to those who care for trauma patients. Many patients can be successfully managed nonoperatively, but there are still patients that require laparotomy. AE is the logical augmentation of damage control techniques for controlling hemorrhage. However, given the nature and severity of these injuries, these therapies are not without complications. MHN was found to be a common complication in our study. It tended to occur in high-grade injures, was associated with higher complication rates, longer hospital length of stay, and higher transfusion requirements. Management of MHN can be challenging. Factors that still need to be elucidated are the role of perihepatic packing and timing of second look operation.

Pulmonary contusion (PC) is commonly sustained in motor vehicle crash. This study utilizes the Crash Injury Research and Engineering Network (CIREN) database and vehicle crash tests to characterize the occupants and loading characteristics associated with PC. A technique to match CIREN cases to vehicle crash tests is applied to quantify the thoracic loading associated with this injury. ⋯ Quantified loading at the chest wall indicative of PC and chest injury in motor vehicle crash is valuable boundary condition data for bench-top studies or computer simulations focused on this injury. In addition, because PC often exhibits a delayed onset, knowing the population and crash modes highly associated with this injury may promote earlier detection and improved management of this injury.

Controversy swirls about optimal control of life-threatening hemorrhage from an injured extremity whether in combat in the Middle East or in trauma care at home. Left unanswered are four critical questions: (1) What is the simplest tourniquet available? (2) Can it be used below the elbow and the knee? (3) Is pain a factor? (4) What data support so called "Pressure Points?" ⋯ Our data indicate that all tourniquets can be used successfully below the knee or elbow. The cloth and windlass is the easiest to apply. It is probably the most readily available or simplest to procure/improvise. Pain is irrelevant. "Pressure Point Control" of extremity arterial hemorrhage is a euphemistic misnomer.
