Comparative Study
Facial nerve decompression surgery in patients with temporal bone trauma: analysis of 66 cases.
In the treatment of facial nerve paralysis after temporal bone trauma, it is important to appropriately determine whether nerve decompression surgery is indicated. The aim of this study was to examine the efficacy of facial nerve decompression surgery according to fracture location and the ideal time for surgery after trauma by analyzing the therapeutic outcome of traumatic facial nerve paralysis. ⋯ The results of this study demonstrated that the ideal time for decompression surgery for facial nerve paralysis after temporal bone fracture was the first 2 weeks after trauma in patients with severe, immediate-onset paralysis. Our study also showed that surgery should be performed within 2 months at the latest. These findings provide useful information for patients and help to determine the priority of treatment when concomitant disease exists.

Controlled Clinical Trial
Continuous intercostal nerve blockade for rib fractures: ready for primetime?
Providing analgesia for patients with rib fractures continues to be a management challenge. The objective of this study was to examine our experience with the use of a continuous intercostal nerve block (CINB). Although this technique is being used, little data have been published documenting its use and efficacy. We hypothesized that a CINB would provide excellent analgesia, improve pulmonary function, and decrease length of stay (LOS). ⋯ Utilization of CINB significantly improved pulmonary function, pain control, and shortens LOS in patients with rib fractures.

Traumatic sternal fractures occur in approximately 3% to 8% of all blunt trauma patients. Most of these fractures are treated conservatively, but a small number require operative intervention. Only a few studies have reported operative fixation of sternal fractures, and no investigation to our knowledge has systematically reviewed the literature on this intervention. ⋯ Although the outcomes were generally positive, only one-half of the articles documented patient follow-up. In future studies, focus needs to be placed on long-term results and specific indications for surgery. The first step toward a standardized sternal fracture operative trial must be a prospective study of incidence and nonoperative long-term outcomes. It is likely that as the interest and demand for plate fixation increases, the demand for orthopedic involvement with sternal fractures will also increase.

The treatment of interprosthetic femoral fractures is challenging because of several factors. Poor bone stock, advanced age, potential prosthetic instability, and limited fracture fixation options both proximally and distally can complicate standard femur fracture treatment procedures. The purpose of this report was to describe our experience treating interprosthetic femoral fractures, providing an emphasis on treatment principles and specific intraoperative management. ⋯ The principles for treatment of isolated periprosthetic fractures are useful to guide the fixation of interprosthetic fractures. Locked plating is an effective method for the treatment of interprosthetic femoral fractures. Bypassing the adjacent prosthesis by a minimum of two femoral diameters is a necessary technique to prevent a stress riser.

Comparative Study
Pseudomonas aeruginosa potentiates the lethal effect of intestinal ischemia-reperfusion injury: the role of in vivo virulence activation.
Experimental models of intestinal ischemia-reperfusion (IIR) injury are invariably performed in mice harboring their normal commensal flora, even though multiple IIR events occur in humans during prolonged intensive care confinement when they are colonized by a highly pathogenic hospital flora. The aims of this study were to determine whether the presence of the human pathogen Pseudomonas aeruginosa in the distal intestine potentiates the lethality of mice exposed to IIR and to determine what role any in vivo virulence activation plays in the observed mortality. ⋯ The presence of intestinal P. aeruginosa potentiates the lethal effect of IIR in mice in part due to in vivo virulence activation of its epithelial barrier disrupting protein PA-IL.
