BACKGROUND Studies have shown that 27% to 38% of girls with adolescent idiopathic scoliosis have systemic osteopenia. The aim of this study was to investigate whether osteopenia could serve as one of the important prognostic factors in predicting curve progression. METHODS A prospective study was performed in 324 adolescent girls with adolescent(More)
STUDY DESIGN A cross-sectional study in girls with adolescent idiopathic scoliosis (AIS) and healthy counterparts of similar age. OBJECTIVES To study the association of bone mass with anthropometric parameters, bone turnover, and calcium intake in 621 girls with AIS, aged 11-6-years, and compare the results with 300 healthy girls of similar age. SUMMARY(More)
Generalized osteopenia and spinal deformity occur concomitantly in adolescent idiopathic scoliosis (AIS) during the peripubertal period. No large-scale study has been performed to reveal the link between scoliotic deformity and bone-mineral status in AIS. In a cross-sectional study, the extent of scoliotic-curve severity in relation to bone-mineral status(More)

This study is a prospective cluster-randomized controlled clinical trial involving 710 elderly subjects to investigate the long-term effects of low-magnitude high-frequency vibration (LMHFV) on fall and fracture rates, muscle performance, and bone quality. The results confirmed that LMHFV is effective in reducing fall incidence and enhancing muscle(More)
BACKGROUND & AIMS Current guidelines recommend testing for Helicobacter pylori infection among users of low-dose aspirin (ASA) who are at high risk for developing ulcers. However, it is not clear whether this strategy affects long-term risk of ulcer bleeding. We assessed the utility of testing ASA users with a high risk of ulcer bleeding for H pylori(More)
STUDY DESIGN A case-control study comparing bone quality in Adolescent Idiopathic Scoliosis (AIS) with normal controls. OBJECTIVE To evaluate bone quality with quantitative ultrasound (QUS) in AIS and normal controls so as to detect any derangement in bone quality among AIS subjects. SUMMARY OF BACKGROUND DATA AIS is characterized by complex spinal(More)
BACKGROUND Complete colonoscopy examination cannot be performed in as many as 10% of cases. The new 9.2-mm ultrathin colonoscope (UTC) with an extra bending section may improve procedure tolerance and allow improvement in colonoscopy completion rate compared with a 12.9-mm standard colonoscope (SC). OBJECTIVE To compare the performance of the 9.2-mm UTC(More)
