Multicenter Study Comparative StudyRegional differences in patient characteristics, case management, and outcomes in traumatic brain injury: experience from the tirilazad trials.
Regional differences have been shown in patient characteristics and case management within multiple unselected series of patients suffering from traumatic brain injury (TBI). One might expect that such regional heterogeneity would be small in a more selected population of a randomized clinical trial. The goal of this study was to examine what regional differences in patient characteristics, case management, and outcomes exist between continents and among countries within a patient population included in a randomized clinical trial. ⋯ Despite the use of a strict study protocol, considerable differences in patient characteristics and case management exist between continents and among countries, reflecting variations in social, cultural, and organizational aspects. Outcomes of TBI may be worse in Europe compared with North America, but this finding requires further study.

Randomized Controlled Trial Clinical TrialEffects of decreasing endotracheal tube cuff pressures during neck retraction for anterior cervical spine surgery.
The authors' goal was to determine whether the incidence of postoperative sore throat, hoarseness, and dysphagia associated with anterior spine surgery is reduced by maintaining endotracheal tube cuff pressure (ETCP) at 20 mm Hg during the period of neck retraction. ⋯ The results of this study suggest the following three predictors of postoperative throat discomfort following anterior cervical spine surgery in which neck retraction is performed: increased ETCP during neck retraction (sore throat), neck retraction time (dysphagia), and female sex (sore throat and hoarseness). The simple maneuver of decreasing ETCP to 20 mm Hg may be helpful in improving patient comfort following anterior cervical spine surgery.

Validity and reliability of the Short Form-36 in cervical spondylotic myelopathy.
Validity (the extent to which a test measures what it is intended to measure) and reliability (the stability and reproducibility of measures of the same concept over time or across methods of gathering data) are important characteristics of any outcomes instrument. Generic outcomes instruments are designed for use in any population; however, their validity and reliability in particular diseases should be verified to ensure their appropriateness for use in that disease. In this study the authors assessed the validity and reliability of the Medical Outcomes Study Short Form-36 (SF-36), a generic outcomes instrument, in a population of patients with cervical spondylotic myelopathy (CSM). ⋯ The SF-36 provides valid and reliable data on patients with CSM.

Reduction of transfusion rates in the surgical correction of sagittal synostosis.
As public concern about the risks of blood transfusions increased in the mid-1990s, avoidance of transfusions became a goal of surgery for sagittal synostosis. This study was performed to confirm a hypothesized reduction in transfusion rates in recent years and to identify factors associated with both the need for transfusion and low postoperative levels of hemoglobin. ⋯ Low blood transfusion rates were achieved using simple intraoperative techniques and by accepting a low level of postoperative hemoglobin.
