This study aimed to identify early radiologic signs that are predictive of hemorrhage progression and clinical deterioration in patients with traumatic cerebral contusion. We hypothesized that contrast extravasation (CE) and blood-brain barrier disruption might be associated with hemorrhage progression, brain edema, and clinical deterioration in these patients. ⋯ Early parenchymal CE is associated with hemorrhage progression, cerebral edema, clinical deterioration, and need for subsequent surgery. These patients should be monitored closely, and early surgery may be needed if deterioration occurs. Further elucidation of the pathophysiology is needed to formulate effective treatment for these high-risk patients.

Cardiopulmonary, histologic, and inflammatory effects of intravenous Na2S after blunt chest trauma-induced lung contusion in mice.
When used as a pretreatment, hydrogen sulfide (H2S) either attenuated or aggravated lung injury. Therefore, we tested the hypothesis whether posttreatment intravenous Na2S (sulfide) may attenuate lung injury. ⋯ Posttreatment sulfide infusion after blunt chest trauma did not affect the impaired lung mechanics and gas exchange but attenuated stress protein expression and apoptotic cell death. This protective effect was amplified by moderate hypothermia. The simultaneous reduction in cystathionine-β synthase and cystathionine-γ lyase expression supports the role of H2S-generating enzymes as an adaptive response during stress states.

To evaluate the operative method and clinical outcome for the treatment of posttraumatic equinus deformity and concomitant soft tissue defect of the heel. ⋯ This study showed that posttraumatic equinus deformity accompanied by soft tissue defect of the heel can be treated effectively with Achilles tendon lengthening, reversed sural fasciocutaneous island flap transfer, and a hinged Ilizarov technique.

Comparative Study
Intubation patterns and outcomes in patients with computed tomography-verified traumatic brain injury.
Studies evaluating traumatic brain injury (TBI) patients have shown an association between prehospital (PH) intubation and worse outcomes. However, previous studies have used surrogates, e.g., Glasgow Coma Scale (GCS) score ≤8 and Abbreviated Injury Severity Scale (AIS) score ≥3, which may overestimate the true presence of TBI. This study evaluated the impact of PH intubation in patients with PH GCS score ≤8 and radiographically proven TBI. ⋯ Patients with PH GCS score ≤8 and proven TBI had a high overall rate of intubation (>90%). PH intubation seems to be a marker for more severe injury and conveyed no increased risk for mortality over ED intubation.

Anti-vehicle mines and improvised explosive devices remain the most prevalent threat to coalition troops operating in Iraq and Afghanistan. Detonation of these devices causes rapid deflection of the vehicle floor resulting in severe injuries to calcaneus. Anecdotally referred to as a "deck-slap" injury, there have been no studies evaluating the pattern of injury or the effect of these potentially devastating injuries since World War II. Therefore, the aim of this study is to determine the pattern of injury, medical management, and functional outcome of UK Service Personnel sustaining calcaneal injuries from under-vehicle explosions. ⋯ Calcaneal injuries following under-vehicle explosions are commonly associated with significant multiple injuries including severe lower limb injury. The frequency of associated spinal injuries mandates radiologic evaluation of the spine in all such patients. The severity of the hindfoot injury is reflected by the high infection rate and amputation rate. Only a small proportion of casualties were able to return to preinjury military duties.
