The posterior skeletal thorax: rib-vertebral angle and axial vertebral rotation asymmetries in adolescent idiopathic scoliosis.
The deformity of the ribcage in thoracic adolescent idiopathic scoliosis (AIS) is viewed by most as being secondary to the spinal deformity, though a few consider it primary or involved in curve aggravation. Those who consider it primary ascribe pathogenetic significance to rib-vertebra angle asymmetry. In thoracic AIS, supra-apical rib-vertebra angle differences (RVADs) are reported to be associated with the severity of the Cobb angle. ⋯ RVADs are largest at two and three vertebral levels above the apex where they correlate significantly and positively with Cobb angle and AVT but not AVR. In right thoracic AIS, the cause(s) of the RVA asymmetries is unknown: it may result from trunk muscle imbalance, or from ribs adjusting passively within the constraint of the fourth column of the spine to increasing spinal curvature from whatever cause. Several possible mechanisms may drive axial vertebral rotation including, biplanar spinal asymmetry, relative anterior spinal overgrowth, dorsal shear forces in the presence of normal vertebral axial rotation, asymmetry of rib linear growth, trunk muscle imbalance causing rib-vertebra angle asymmetry weakening the spinal rotation-defending system of bipedal gait, and CNS mechanisms.

Comparative StudyDirect versus indirect laryngoscopic visualization in human endotracheal intubation: a tool for virtual anesthesia practice and teleanesthesiology.
When performing the ABC's of care for the trauma patient, airway management is of paramount importance. Management of the airway is often difficult because medical personnel caring for the patient do not commonly intubate patients or manage airways. To accomplish endotracheal intubation, a direct line of sight must be accomplished through the mouth, pharynx and larynx to the glottic opening. ⋯ Indirect "virtual" laryngoscopy is an advanced technology method which will advance the development of teleanesthesiology practice. Videolaryngoscopy is an enabling technology for development of remote telementoring of trainee intubation skills curricula using video enabled distributed learning systems. This research was conducted following an approved University of Nebraska Medical Center institutional review board protocol.

ReviewDiversity in preoperative-assessment data collection, a literature review.
The appropriate anesthetic techniques and care during and after operation rely on data gathered during the preoperative assessment. Because various people are involved, standardization of this process is important. This paper provides a systematic literature review about which data items are collected in the preoperative assessment. ⋯ Our study showed a high diversity of data items in the preoperative assessment. Because of the diversity of patients and treatment options available one undisputed preoperative assessment data set is hard to define. However, to solve the problem of exchangeability of the information at least anesthesiologists should use a same core set of data.

Effects of repeated CPR training in virtual worlds on medical students' performance.
We report on a study that investigates the relationship between repeated training of teams managing a medical emergency (CPR) in a Virtual World and performance outcome measures in a group of 12 medical students. The focus of the training was on individual actions, but also on interaction and behavior in the team. ⋯ Although a pilot study, we found clear indications of improved performance related to reduced number of errors and an increased CPR efficiency. This type of educational technology could be expanded to other groups for a similar purpose because of its easiness to use, adaptability and interactivity.

Comparative StudyErgonomically designed kneeling chairs are they worth it? : Comparison of sagittal lumbar curvature in two different seating postures.
General agreement among researchers suggests that poor seating posture may predispose individuals to developing low back pain. A variety of methods such as ergonomically designed chairs have been developed to assist people to maintain good posture and preserve the 'natural' lumbar curve. The aim of this study was to compare lumbar curvature on an ergonomically designed kneeling chair (EKC) with that on a standard computer chair (SCC), with reference to the standing lumbar curvature. ⋯ There was also a statistically significant difference between the two seated positions (p<0.05). This study suggests that ergonomically designed kneeling chairs set at +20 degrees inclination do maintain standing lumbar curvature to a greater extent than sitting on a standard computer chair with an overall mean difference of 7.633 degrees. Further research with a greater number of subjects and on different chair designs is warranted.
