After splenic trauma, critical decisions regarding operative intervention are often made with the aid of computed axial tomographic (CT) scan findings. No CT scan-based grading scale has been demonstrated to predict accurately which patients require operative or radiologic intervention for their splenic injuries. We hypothesized that use of the most common grading scale, the American Association for the Surgery of Trauma scale, would be associated with low intra- and interreliability scores. We assessed the ability of experienced trauma radiologists to differentiate grade III from grade IV splenic injuries. ⋯ CT imaging is not reliable for identifying grades III and IV splenic injury, as experienced radiologists often underestimate the magnitude of injury. Interrater reliability is poor. Factors other than the CT grade of splenic injury should determine whether patients require operative or angiographic therapy.

Multicenter Study Comparative Study
The impact of major trauma: quality-of-life outcomes are worse in women than in men, independent of mechanism and injury severity.
The importance of gender differences in quality of life and psychologic morbidity after major trauma is a newly recognized focus of trauma outcomes research. The Trauma Recovery Project is a large, prospective, epidemiologic study designed to examine multiple outcomes after major trauma, including quality of life (QoL), and psychologic sequelae such as depression and early symptoms of acute stress reaction (SASR). The specific objectives of the present report are to examine gender differences in QoL outcomes and the early incidence of combined depression and SASR after injury, controlling for injury severity, specific body area injured, and mechanism. ⋯ These analyses provide further important and more detailed evidence that women are at risk of worse QoL outcomes and early psychologic morbidity after major trauma than men, independent of mechanism and injury severity. A better understanding of the impact of major trauma in men and women will be an important component of efforts to improve trauma care and long-term outcome in mature trauma systems.

Appropriate and timely antibiotic therapy to treat pneumonia in trauma patients is extremely important. We evaluated the incidence and microbiology of pneumonia stratified by days postadmission and risk factors. ⋯ Unanticipated pathogens were isolated in each class of pneumonia. The clinician must be aware of significant risk factors that may predispose patients to pathogens that are not ordinarily covered with standard antibiotic therapy.

Hepatocyte growth factor (HGF) has a significant effect on the regeneration of epithelial and endothelial cells. Studies have also shown an important role of HGF in wound healing and organ regeneration. Because recent studies indicate that polymorphonuclear leukocytes (PMNLs) store HGF in their specific granules and that HGF can be degranulated in the inflammatory tissue in which activated PMNLs migrate, we evaluated the storage and release of HGF in PMNLs from patients with systemic inflammatory response syndrome (SIRS) and attempted to examine the role of HGF from PMNLs in the systemic inflammatory process. ⋯ Activated PMNLs in SIRS patients increased HGF in their granules and demonstrate enhanced degranulation of HGF. The release of HGF from migrated PMNLs in the inflammatory tissue may play an important role in wound healing and organ regeneration under those conditions.
