Although HIV-infected individuals harbour multiple strains of oral Candida albicans, little is known of their micro-evolution over time. Therefore, a prospective study was conducted with 16 HIV-infected ethnic Chinese individuals with and without symptoms of oropharyngeal candidiasis to evaluate the genotype distribution of oral C. albicans isolates during(More)
BACKGROUND End-stage renal disease (ESRD) is epidemic worldwide. In Hong Kong, the annual incidence of ESRD has risen from 100 pmp (per million population) in 1996 to 140 pmp in 2003. SHARE (Screening for Hong Kong Asymptomatic Renal Population and Evaluation program) is a population-based screening program aimed at identifying the prevalence of(More)
OBJECTIVE We evaluated the effectiveness of local application of mupirocin ointment at the catheter exit site in preventing exit-site infection and peritonitis attributable to gram-positive organisms in continuous ambulatory peritoneal dialysis patients. METHODS This prospective randomized controlled trial included 154 patients. They were randomly(More)
We performed a multicenter, single-blinded, prospective randomized study on the use of a double-bag disconnect system (B) versus a Y-set disconnect system (Y). The peritonitis rate, exit site infection, clinical outcome, and patients' acceptance to the procedure were assessed. A total of 120 new end-stage renal failure patients of three regional hospitals(More)
Both tacrolimus and mycophenolate mofetil (MMF) are potent immunosuppressive agents used in combination for prevention of acute rejection in renal transplantation. We studied the efficacy and safety of tacrolimus/MMF-based primary immunosuppression as well as their pharmacokinetics (PK) in Chinese renal transplant recipients. Oral tacrolimus was initiated(More)
BACKGROUND Severe acute respiratory syndrome (SARS) is a newly emerged infection from a novel coronavirus (SARS-CoV). Apart from fever and respiratory complications, acute renal impairment has been observed in some patients with SARS. Herein, we describe the clinical, pathologic, and laboratory features of the acute renal impairment complicating this new(More)
Recent studies have demonstrated that the self-stimulation phenomenon may provide a useful technique for investigating the rewarding properties of potentially addictive drugs such as morphine. The present study attempted to examine the nature of morphine's effects on self-stimulation by observing changes in rate-intensity functions following morphine(More)
There has been some controversy whether experimenter-administered electrical stimulation of the brain is aversive or simply less reinforcing than that delivered via self-stimulation. Rats with MFB-LH electrodes self-stimulated with high, medium, and low currents and the self-produced rates were tape recorded. In Experiment 1, the rats were allowed to choose(More)
OBJECTIVES To evaluate the effectiveness of sodium ramping (profiling) in reducing hypotensive episodes and symptoms during haemodialysis. DESIGN Prospective study. SETTING Regional hospital, Hong Kong. PATIENTS Thirteen patients who experienced frequent episodes of hypotension and/or symptoms such as cramps, dizziness, chest pain, nausea, vomiting,(More)
