Open reduction and internal fixation of unstable posterior pelvic ring injury provides better bony stability and less long term morbidity than nonoperative treatment. However, open reduction and internal fixation of the posterior pelvis may involve substantial intraoperative blood loss, reported infection rates of 6 to 25%, and wound complications in 25%. Our hypothesis was that percutaneous cannulated iliosacral screws placed by fluoroscopic control would provide early, rapid, definitive stabilization with minimal blood loss, infection, and wound complications. ⋯ Percutaneous iliosacral screw fixation for unstable posterior pelvic disruption provided early fixation with minimal operative time, minimal blood loss, and wound-related morbidity.

This study sought to determine if violence against women is accurately documented in the trauma registry, and if poor documentation in the medical record is associated with incorrect coding in the registry. ⋯ Violence against women often goes undocumented in hospital data systems.

Determine if laparotomy further destabilizes an unstable pelvic injury and increases pelvic volume, and if reduction and stabilization restores pelvic volume and prevents volume changes secondary to laparotomy. ⋯ We believe that the abdominal wall provides stability to an unstable pelvic ring injury via a tension band effect on the iliac wings. Our results demonstrate that a laparotomy further destabilized an open-book pelvic injury and subsequently increased pelvic volume and pubic diastasis. This could potentially increase blood loss from the pelvic injury and delay the tamponade effect of reduction and stabilization. A single-pin external fixator prevents the destabilizing effect of the laparotomy and effectively reduces pelvic volume. These data support reduction and temporary stabilization of unstable pelvic injuries before or concomitantly with laparotomy.

Based on the findings in computed tomography scans, we defined a grading system that is well correlated to the changes of the brainstem and its perimesencephalic cistern during intracranial hypertension. ⋯ Our grading system is easy to use, and is well correlated to give an accurate prediction of outcome in cases with severe head injury based primarily on the results of an initial computed tomography scan, even without clinical information, and it should play a role in the classification of head injury.

The evaluation of various techniques to diagnose or exclude ventilator-associated bacterial pneumonia has been a focus of much research. One such technique involves elastin fiber detection. It has been inferred from previous work that 40% potassium hydroxide preparations of respiratory secretions that demonstrate elastin fibers have a 100% specificity in diagnosing bacterial pneumonia in intubated, mechanically ventilated patients without acute diffuse lung injury. The purpose of this investigation was to ascertain if elastin fibers might be detected in respiratory secretions in acute, diffuse lung injury in the absence of pneumonia (i.e., assess specificity). ⋯ We concluded that seeing these results, given a true specificity of 0.99 inferred from previous work, is highly improbable with a probability of 2.74 x 10(-7). Thus, elastin fiber analysis is likely to be highly nonspecific for diagnosing pneumonia in the setting of acute diffuse lung injury.
