Clinical TrialThe effect of pressure pad location of spinal orthosis on the treatment of adolescent idiopathic scoliosis (AIS).
Patient with moderate AIS is usually prescribed with spinal orthosis aiming to mechanically support and prevent the spine from further deterioration. In the conventional fitting method, pre-brace X-ray is the main reference, thus, the pressure pad of spinal orthosis may not be accurately located to the strategic areas because the spinal deformities could change 3-dimensionally once pressure pad is applied. A high correlation (r > 0.98) between Cobb's angle and spinous process angle (SPA) was found in the recent studies. ⋯ The assessments of in-brace X-rays showed that the mean Cobb's angle of group A decreased from 28.9° (pre-brace) to 18.6° (immediate in-brace) while the mean Cobb's angle of group B decreased from 27.1° (pre-brace) to 22.5° (immediate in-brace). There was a significant difference (p < 0.05) in the correction of Cobb's angle between the two groups. The results showed that accurate pressure pad location does play an important role in the reduction of Cobb's angle and 3D CUS can be considered as a non-invasive and effective assessment tool to improve orthotic treatment of AIS.

Use of a malleable bougie and curved forceps with videolaryngoscopy in airway management training in a cadaver model - a pilot study.
The wider angle of view of videolaryngoscopy versus standard direct laryngoscopy requires an assessment of the adjunctive devices used to facilitate intubation. In this study, subjects performed malleable bougie-assisted intubation and curved forceps removal of a glottic foreign body using videolaryngoscopy on a lightly embalmed cadaver and completed a post-procedure questionnaire. All subjects valued access to the malleable bougie available at their hospitals and 82% valued access to the curved forceps. Malleable bougie and curved forceps seem well-suited to facilitate videolaryngoscopic airway management.

BodyWindows: enhancing a mannequin with projective augmented reality for exploring anatomy, physiology and medical procedures.
Augmented reality offers the potential to radically extend and enhance the capabilities of physical medical simulators such as full-body mannequin trainers. We have developed a system that transforms the surface of a mannequin simulator into both a display screen and an input device. The BodyWindows system enables a user to open, size, and reposition multiple viewports onto the simulator body. ⋯ Viewport windows can be overlapping and show anatomy at different depths, creating the illusion of "cutting" multiple windows into the body to reveal structures at different depths from the surface. The developed low-cost interface employees an IR light pen and the Nintendo Wiimote. We also report experiments using the Microsoft Kinect computer vision sensor to provide a completely hand-gesture based interface.

Nation-wide primary healthcare research network: a privacy protection assessment.
Efficiency and privacy protection are essential when setting up nationwide research networks. This paper investigates the extent to which basic services developed to support the provision of care can be re-used, whilst preserving an acceptable privacy protection level, within a large Belgian primary care research network. ⋯ A short analysis of the current architecture is provided. Our generic model could also be used in other countries.

Analysis of body growth parameters in girls with adolescent idiopathic scoliosis: single thoracic idiopathic scoliosis versus single lumbar idiopathic scoliosis.
Abnormal pattern of growth has been reported in adolescent idiopathic scoliosis (AIS) patients. However, the sequential changes of growth in different curve types of AIS have not been properly studied. The present study aimed to investigate the body growth characteristics of girls with single thoracic idiopathic scoliosis and lumbar idiopathic scoliosis in China. 339 AIS girls and 3914 healthy girls, aged 10~17yr, were included. ⋯ The standing and sitting height between thoracic and lumbar AIS girls were similar during the pubertal period. Compared to healthy girls at the same age, thoracic and lumbar AIS girls had a significantly higher corrected standing, sitting height and leg length. In addition, thoracic AIS girls are leaner than healthy girls.
