Brain injury as well as early inflammatory and endocrine responses were found to be indicators for infectious complications in patients with multiple injuries. In this context, brain-derived inflammatory response as well as centrally triggered neuroendocrine activation and systemic immunodepression seem to be of major importance. Therefore, we hypothesize that a circulating index of inflammatory or endocrine function measured soon after brain injury (in patients with admission Glasgow Coma Scale [GCS] score of 4-7) would discriminate severe from moderate injury as indexed by GCS status on postinjury day 7. ⋯ The IL-6 plasma level 1 day after the acute event with a cut-off of 100 pg/mL (Immulite) seems to be a predictor for short-term prognosis and infectious complications in brain-injured patients.

Multiple investigations have demonstrated that hypertonic saline (HS) diminishes the response of polymorphonuclear leukocytes (PMNs) to stimulation. Recent meta-analysis suggests that hypertonic saline in dextran (HSD) is clinically superior to HS. No work to date has examined the effect of added dextran on this immunomodulatory property. ⋯ The alterations in PMN function associated with HS are not changed or attenuated by the addition of dextran, suggesting that the clinically superior HSD may have effects similar to HS in mitigating the tissue damage associated with activated PMNs.

Rectal and lower urinary tract injuries in pelvic fractures can lead to significant complications. We sought to determine whether fracture locations could serve as markers for injury. ⋯ Certain fracture locations are associated with increased risk for rectal, bladder, or urethral injury. Fractures involving these locations should prompt further work-up for assessment.
