The Glasgow Coma Scale (GCS) has served as an assessment tool in head trauma and as a measure of physiologic derangement in outcome models (e.g., TRISS and Acute Physiology and Chronic Health Evaluation), but it has not been rigorously examined as a predictor of outcome. ⋯ Because the motor component of the GCS contains virtually all the information of the GCS itself, can be measured in intubated patients, and is much better behaved statistically than the GCS, we believe that the motor component of the GCS should replace the GCS in outcome prediction models. Because the m component is nonlinear in the log odds of survival, however, it should be mathematically transformed before its inclusion in broader outcome prediction models.

Traumatic pulmonary pseudocysts (TPPs) are rare sequelae of blunt chest trauma. We present a retrospective review of TPPs observed in our hospital and discuss the diagnosis, treatment, and complications of these unusual lesions. ⋯ TPPs are often missed by chest radiography, particularly when it is obtained in the supine position, whereas computed tomographic scan allows the identification of these lesions in all cases. TPPs are self-limiting, benign lesions that usually require no specific therapy. Surgical treatment is indicated in rare instances and only when complications occur.

Duodenal injury secondary to blunt trauma continues to pose a diagnostic challenge. The purpose of this study is to evaluate the cause, radiologic findings, and management of duodenal injuries from a Level I pediatric trauma center. ⋯ CT scanning remains a valuable tool in the diagnosis of blunt duodenal injuries in children. Although extravasation of oral contrast was not beneficial, the presence of extraluminal air was highly suggestive of perforation. The vast majority of hematomas were successfully managed nonoperatively, and duodenorrhaphy was safe and effective therapy for perforations.

Blunt chest trauma is an important clinical problem leading to injury of the heart and lungs that may be fatal. Experimental models in large animals have been developed previously. This study was aimed at developing a small-animal (rat) model for the purpose of evaluating blunt chest trauma. ⋯ This study has established a useful model for the study of blunt chest trauma in a small animal (rat). Blunt chest trauma is associated with cardiac arrhythmia, which may be fatal. Injury to the heart may not correlate with serious cardiac arrhythmia resulting in death, lending credence to the concept of cardiac concussion or commotio cordis. Lung contusion is always more obvious than morphologic injury to the heart.

The protective effect of female gender on posttraumatic mortality or acute complications after traumatic brain injury (TBI) has been postulated. This effect might be seen if TBIs were analyzed by severity. To assess potential gender effects, we performed a retrospective case-controlled study matching female patients to male counterparts for overall injury severity; hemodynamic status at admission; and head, chest, and abdomen Abbreviated Injury Scale score. ⋯ Gender does not play a role in posttraumatic mortality or in the incidence of acute complications after any degree of TBI.
