incident reporting in acute pain management.incident reporting is an effective tool for continuous quality improvement in clinical practice. a prospective study on voluntary incident reporting in pain management was conducted at a major teaching hospital in hong kong. over a 12-month period, 53 incidents were reported in 1275 patients who received pain relief treatments which were supervised by the acute pain service. the majority of the incidents were first detected by the pain team. the most common incidents involved delivery circuits, ...19989797515
frequent microsatellite instability and mismatch repair gene mutations in young chinese patients with colorectal cancer.the incidence of colorectal cancer in persons under 46 years of age is substantially higher in hong kong than in scotland and many other countries. consequently, we examined whether there is a hereditary predisposition for colorectal cancer in this southern chinese population.199910413423
global epidemiology of influenza: past and present.pandemics are the most dramatic presentation of influenza. three have occurred in the twentieth century: the 1918 h1n1 pandemic, the 1957 h2n2 pandemic, and the 1968 h3n2 pandemic. the tools of molecular epidemiology have been applied in an attempt to determine the origin of pandemic viruses and to understand what made them such successful pathogens. an excellent example of this avenue of research is the recent phylogenetic analysis of genes of the virus that caused the devastating 1918 pandemic ...200010774473
antigenic and genetic analyses of h5 influenza viruses isolated from ducks in asia.the hemagglutinin (ha) of six h5 influenza virus strains isolated from ducks in japan and china in 1976 to 1996 were analyzed antigenically and genetically. antigenic analysis using a panel of monoclonal antibodies revealed that the ha of h5 influenza viruses isolated from ducks are antigenically closely related to each other. phylogenetic analysis indicates that the isolates from ducks in hokkaido were derived from an ancestor common with the highly pathogenic isolates from chickens and humans ...199910414025
low yield of chest radiography in screening for active pulmonary tuberculosis in hiv-infected patients in hong kong.this study assessed the usefulness of routine chest radiography for detecting active pulmonary tuberculosis in persons infected with human immunodeficiency virus (hiv) without suggestive symptoms in hong kong. tuberculosis is common in this locality and tuberculosis/hiv co-infection has been a frequent and significant problem. records of patients attending the largest hiv clinic were reviewed. three hundred and eleven routine chest radiographs were performed among 191 hiv-infected patients with ...199910414885
post-mortem investigations on stranded dolphins and porpoises from hong kong waters.stranded cetaceans reported from the territorial waters of hong kong during the period may 1993 to march 1998 were examined to establish factors that may have contributed to their death. during the current study, 28 indo-pacific hump-backed dolphins (sousa chinensis), 32 finless porpoises (neophocaena phocaenoides), and four bottlenose dolphins (tursiops truncatus) were necropsied. bacteria (15 species) were isolated from nine animals. of these bacteria, 47% were of possible fecal origin reflect ...200010813617
