Limited data suggest that outdoor air pollution (such as ambient air pollution or traffic-related air pollution) and indoor air pollution (such as second-hand smoking and biomass fuel combustion exposure) are associated with the development of chronic obstructive pulmonary disease (COPD), but there is insufficient evidence to prove a causal relationship at(More)

AIMS To assess any relationship between the levels of ambient air pollutants and hospital admissions for chronic obstructive pulmonary disease (COPD) in Hong Kong. METHODS A retrospective ecological study was undertaken. Data of daily emergency hospital admissions to 15 major hospitals in Hong Kong for COPD and indices of air pollutants (sulphur dioxide(More)
It is common practice to use a forced expiratory volume in one second (FEV(1))/ forced vital capacity (FVC) ratio of <70% as evidence of airflow obstruction. As the FEV(1)/FVC ratio falls with age, the lower limit of normal range (LLN), defined as the bottom 5% in a health reference population, of FEV(1)/FVC ratio has been suggested as a better index to(More)
BACKGROUND A randomised controlled study was undertaken to examine the effect of nasal continuous positive airway pressure (CPAP) on 24 hour systemic blood pressure (BP) in patients with obstructive sleep apnoea (OSA). METHODS Patients were fitted with an ambulatory BP measuring device as outpatients during normal activities and recorded for 24 hours(More)
OBJECTIVE To examine the impact of severe acute respiratory syndrome (SARS) on pulmonary function, exercise capacity, and health-related quality of life (HRQoL) among survivors. METHODS 110 survivors with confirmed SARS were evaluated at the Prince of Wales Hospital, HK at the end of 3 and 6 months after symptom onset. The assessment included lung volumes(More)
Measurement of fractional exhaled nitric oxide concentration (FeNO) has been proposed as a useful biomarker for monitoring and management of airway diseases. Limited information is available regarding reference levels of FeNO levels in Chinese adults. This study aimed to investigate the reference equation and determinants of FeNO in Chinese adults. 1093(More)
Our recent studies showed that one session of transcutaneous electrical nerve stimulation on acupoints (Acu-TENS) improved forced expiratory volume in 1s (FEV(1)) in patients with chronic obstructive pulmonary disease (COPD). This study investigated the effect of 4-week Acu-TENS on physical and psychosocial function in these patients. Twenty-eight patients(More)
OBJECTIVES To assess the prevalence of allergic rhinitis in adult patients with asthma in Hong Kong, and to compare the morbidity endured by asthma patients with and without allergic rhinitis. DESIGN Cross-sectional study. SETTING Respiratory clinics of four major public hospitals in Hong Kong. PATIENTS A total of 600 adults with asthma were recruited(More)
PURPOSE To date, there have been few studies examining quality of life (QOL) in older patients with chronic obstructive pulmonary disease (COPD) in China. The aim of the study was to assess QOL in Chinese older patients with COPD and explore its demographic and clinical correlates. DESIGN AND METHODS Case-control study of 142 outpatients with COPD and 218(More)
OBJECTIVE To examine the long-term effect of CPAP on carotid artery intima-media thickness (IMT) in patients with Obstructive sleep apnea syndrome(OSAS). METHODS A prospective observational study over 12 months at a teaching hospital on 50 patients newly diagnosed with OSAS who received CPAP or conservative treatment (CT). Carotid IMT was assessed with(More)
