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)
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)
BACKGROUND & AIMS Colorectal cancer (CRC) is the second-most common cancer in Hong Kong. Relatives of patients with CRC have an increased risk of colorectal neoplasm. We assessed the prevalence of advanced neoplasms among asymptomatic siblings of patients with CRC. METHODS Patients with CRC were identified from the Prince of Wales Hospital CRC Surgery(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)
UNLABELLED 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(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)
This cross sectional study of 290 Chinese children aged 8-18 years, evaluated a Chinese version of the self-reported Pubertal Development Scale (PDS) against both raters' and self-reported Tanner assessment of pubertal status. Children completed both the self-reported PDS and self-reported Tanner pubertal questionnaire prior to physical examination through(More)
BACKGROUND Poor adherence to gastroprotective agents (GPAs) is common among users of nonsteroidal anti-inflammatory drugs (NSAIDs) or low-dose aspirin (ASA). There are little data on the utilization of GPAs among NSAID and ASA users complicated by ulcer bleeding. AIM To study the utilization of GPA among NSAID and ASA ulcers before the onset of ulcer(More)
Generalized low bone mass has been well documented in patients with adolescent idiopathic scoliosis (AIS). However, studies linking calcium-intake (CA), weight-bearing physical-activity (PA) and bone mass of AIS are lacking. We aimed to study the relationship between CA, PA and bone mass in AIS girls and compared to those of healthy non-AIS controls during(More)
BACKGROUND The population in Hong Kong is mainly Chinese, but their lifestyle is increasingly westernized. It is uncertain whether the trends of stroke in Hong Kong would follow a Chinese or Western pattern. This is the first study to examine the trends of ischemic and hemorrhagic stroke in Hong Kong between 1999 and 2007 with a view to providing data for(More)
