Comparative Study
Immunologic function in the elderly after injury--the neutrophil and innate immunity.
Aging is associated with a decline in immune function. This may contribute to decreased ability of an elderly patient to mount an appropriate innate inflammatory response when injured. This study examined elderly trauma patients to determine whether there was a difference in neutrophil response to injury when compared with controls. ⋯ Injury results in differences in innate immune function in the elderly when compared with controls. The clinical significance of this is uncertain and warrants further investigation.

Femoral shaft fractures are associated with acute respiratory distress syndrome (ARDS). The idea that primary intramedullary nailing increases the incidence of ARDS has theoretical support. Our approach to treating femoral fractures in patients with multiple traumatic injuries is to perform reamed nailing after adequate resuscitation has been shown by normalizing lactate plus optimized ventilatory and hemodynamic parameters. Damage control orthopedics (DCO) with primary external fixation usually is reserved for those rare patients who do not respond to resuscitation. Our hypothesis was that this approach yields a low rate of ARDS. ⋯ In the context of resuscitation before reamed intramedullary nailing of femoral shaft fractures, our rate of ARDS was lower (p < 0.001) than that of a similar study reported in the literature in which the DCO approach was used in up to 36% of patients (p < 0.001) and was more in keeping with previously reported rates of ARDS. This remained true despite frequent use of early reamed femoral nailing and infrequent use of DCO. An explanation for the discrepancy between the centers might be differences in preoperative resuscitation or medical care provided to treat shock.

Hyperglycemia is associated with increased mortality in the severely injured; intensive insulin protocols reduce mortality, improve wound healing, and decrease susceptibility to infection. High glucose variability creates challenges to glycemic control and may be a marker of poor outcome. We wondered whether glycemic variability alone might identify patients at higher risk of death. ⋯ High glucose variability (>50% of values outside 80-110 mg/dL) is associated with increased mortality in the severely burned. Individuals with frequent excursions outside the glucose target range of 80 mg/dL to 110 mg/dL are at greater risk of death.

Comparative Study
Genitourinary injuries in pelvic fracture morbidity and mortality using the National Trauma Data Bank.
Pelvic fractures from blunt force trauma place the bladder and urethra at risk for injury, often resulting in significant complications. We sought to compare morbidity, mortality, and health care resource utilization in patients with and without genitourinary injuries (GUI) associated with pelvic fractures. ⋯ Patients sustaining a pelvic fracture with GUI have an increase in morbidity. Although GUI was not an independent predictor of mortality, patients who sustained a pelvic fracture with GUI had a greater number of concomitant injuries resulting in an increase in overall mortality compared with those without an associated GUI.
