Early complications associated with cephalomedullary nail for intertrochanteric hip fractures.
Use of cephalomedullary devices for pertrochanteric fractures has been associated with complications of cutout, fracture distal to the tip of the implant, infection, and hardware failure. The goal of recent design changes (a trapezoidal shape of the proximal device, with interdigitation of the cephalocervical screws) in cephalomedullary nails was to improve fracture fixation and stability of pertrochanteric fractures. This is a retrospective review of the first 127 surgeries using this new cephalomedullary nail to review early complications seen with this device. ⋯ In our study population, we found this newer cephalomedullary device had complications similar to those reported with devices in previous studies.

Readmission of trauma patients in a nonacademic Level II trauma center.
Readmission of trauma patients has been identified as a quality indicator for trauma care. Few if any studies on this topic can be found from a nonacademic trauma center. The objectives of the study were to determine the rate, cause, and preventability for readmission and to identify predictors of readmission in a nonacademic trauma center. ⋯ The incidence of readmissions was similar to published data from academic trauma centers, but the reason for readmission and the need for surgery at readmission were very different. Potentially preventable readmissions have not been well addressed in literature. Therefore, further multicenter studies that include nonacademic trauma centers are needed to analyze this complicated problem.

CPSI-121 pharmacologically prevents intestinal barrier dysfunction after cutaneous burn through a vagus nerve-dependent mechanism.
We have recently demonstrated the protective effects of electrical stimulation of the vagus nerve in prevention of gut injury after severe burn. Here we evaluate the potential for a pharmacologic agonist of the vagus nerve as an approach to regulate outcomes in preclinical models. We tested a new generation of guanylhydrazone-derived compounds, CPSI-121; a compound that may activate the parasympathetic nervous system through poorly understood mechanisms to determine whether we could prevent intestinal mucosal barrier breakdown. ⋯ Similar to direct electrical VNS, CPSI-121 effectively protects the intestinal mucosal barrier from breakdown after severe burn. We suggest that this could represent a noninvasive therapy to prevent end-organ dysfunction after trauma that would be administered during resuscitation.

Incidence and pattern of cervical spine injury in blunt assault: it is not how they are hit, but how they fall.
The injury mechanism of blunt cervical spine injury (CSI) involves two forces: (1) an acceleration-deceleration force or change in velocity (delta v) that causes significant head and neck movement, resulting in flexion-extension injury pattern and (2) a direct force to the head or face against an immovable object with force transmitted down the cervical spine. Combining those two forces creates what bioengineers call imparted energy (IE). In blunt assault to the head or face, IE is low; hence, the reported incidence of CSI is low. The goal of our study was to identify the incidence, pattern, and outcome of CSI in blunt assaulted patients. ⋯ The incidence of CSI after blunt assault is very low, and the pattern of injury and severity is related to a fall occurring after the assault. Our results should encourage clinicians to find out if patient falls after the assault.
