Ventilation of Acute Respiratory Distress Syndrome (ARDS) is a challenge, and there is definitely a need for lack of variations between delivered and set tidal volume (Vt). We have assessed the ability of the ventilator T-birdVS02 and LTV-1000 to deliver to a lung model with ARDS a set Vt at different simulated altitudes. ⋯ Clinicians involved in aerial evacuations must keep in mind the performance and limitations of their ventilator system.

Individuals hospitalized after physical trauma are at heightened risk for mental disorders. We examined prevalence rates of both posttraumatic stress disorder (PTSD) and major depression at 6 and 12 months in a sample of 677 individuals experiencing different types of trauma who were representative of physical trauma survivors hospitalized in Los Angeles County trauma centers. Demographic and injury-related risk factors for these disorders were also evaluated. ⋯ Key demographic and injury characteristics may enhance identification of at-risk trauma survivors who would benefit from targeted screening, patient education, and early intervention efforts.

The severity of the injury is the most important factor to return to work (RTW) when it comes to hand injuries. The purpose of our study is to examine the relationship between the initial anatomic severity, evaluated by the Hand Injury Severity Scoring (HISS) system, and probability of RTW in occupational hand injured patients. ⋯ HISS is a useful instrument to predict the opportunity of RTW while restricted to the compensated patients. We also verified that the relationship between HISS severity and the probability of RTW existed for groups but not for individual patients.

Randomized Controlled Trial Comparative Study
Monoaxial versus polyaxial screw insertion in angular stable plate fixation of proximal humeral fractures: radiographic analysis of a prospective randomized study.
Monoaxial and polyaxial screw insertion are used in angular stable plating of displaced proximal humeral fractures. Aim of the study was to compare both fixation techniques by radiographic evaluation. ⋯ Monoaxial and polyaxial screw insertion allow for mechanical stabilization in angular stable plating of unstable proximal humerus fractures. Radiographic evidence of secondary varus displacement of > 10-degree angle and screw cut out was seen similarly often in both fixation techniques. To avoid secondary varus displacement and screw cut out, restoration of a humeral head-shaft angle of > 130 degrees seems to be important in monoaxial and polyaxial fixation of proximal humeral fractures.

We retrospectively analyzed the characteristics and treatment of maxillofacial injuries in the patients who were victims of the Wenchuan earthquake on May 12, 2008 to improve the maxillofacial injuries database and provide reference on patients' treatment after earthquake. ⋯ Our analysis of the characteristics of maxillofacial injuries after the Wenchuan earthquake may improve our emergency treatment procedures in future disaster situations.
