Spatial clustering of SARS in Hong Kong.

1. Geographic information system (GIS) can be applied during an acute infectious disease outbreak to reveal new geospatial information in addition to standard field epidemiological analyses. 2. When applied in real time during the onset and evolution of an epidemic, GIS can monitor and enhance understanding of the transmission dynamics of an infectious agent, thereby facilitating the design, implementation and evaluation of potential intervention strategies.published_or_final_versio

Properties of a hand-printed Chinese character recognizer based on contexted vector quantization

A hand-printed Chinese character recognizer based on Contextual Vector Quantization (CVQ) has been built previously. In this paper, several properties of the recognizer will be discussed and the recognizer of 4516 Chinese characters has a successful rate of 91.0%. Then the output of the recognizer is passed to a language model which when applied to recognize a passage of about 1200 characters raises the rate from 91.5% to 97.5%.published_or_final_versio

The efficacy of extracorporeal shock wave lithotripsy in the treatment of ureteric stones

This study was conducted to evaluate the efficacy of in situ extracorporeal shock wave lithotripsy treatment of ureteric stones using the Dornier MFL 5000 lithotripter. From March 1991 to June 1994, 184 patients received in situ extracorporeal shock wave lithotripsy treatment. The overall success rate was 76% (77% for upper; 69% for middle; and 81% for lower ureteric stones, respectively). The level and size of the stones did not affect the final outcome significantly. An average of 1.23 sessions were required for each patient and the rate of major auxiliary intervention was 21%. We conclude that extracorporeal shock wave lithotripsy is an effective treatment for ureteric stones.published_or_final_versio

Management of ureteric calculi: the pendulum swings

Extracorporeal shock wave lithotripsy (ESWL) for treatment of ureteral calculi has gained wide popularity because of its non-invasive and ambulatory nature. The success rate using the Dornier MFL 5000 is about 77%, but retreatment is often required and stone clearance is gradual. Ureteroscopic lithotripsy (URSL) used to be performed as an in-patient procedure. With the introduction of Holmium laser and establishment of day surgery service, out-patient URSL carries a success rate of 93% and offers immediate stone clearance. It is an attractive alternative for low surgical risk patients as a primary treatment modality.published_or_final_versio

Optical properties of organic materials for optical communication devices

2005 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS 2005), Hong Kong, 13-16 December 2005Recently, organic materials have been considered as a potential candidate for making optoelectronic devices. In order to optimize the performance of the optoelectronic devices, the absolute refractive index and absorption coefficient of the organic materials have to be determined. In this article, the absolute optical properties of two novel bipolar organic materials will be investigated through ellipsometry and modeling using Lorentz Oscillator model and stimulated annealing algorithm. © 2005 IEEE.published_or_final_versio

Effectiveness of a Chinese herbal medicine preparation in the treatment of cough in uncomplicated upper respiratory tract infection: a randomised double-blinded placebo-control trial

BACKGROUND: Rigorous scientific and well-designed clinical trials to evaluate the effect of traditional Chinese medicine (TCM) is lacking. We, therefore, designed this study to evaluate the effectiveness of a commonly used TCM preparation in treating acute cough of uncomplicated URTI in adults and to search for a safe, effective and affordable alternative treatment for this common condition. METHODS: A randomised, double-blinded, placebo-control study comparing this TCM preparation with a placebo was conducted in 82 patients who attended the Family Medicine Training Centre, Prince of Wales Hospital, Hong Kong between November and December, 2003. The TCM herbal preparation includes nine commonly used TCM herbs for cough such as chuanbei, fangfeng, jiegeng, gancao and baibu (see Table 1) The treatment lasted for 5 days and patients were followed-up for another 6 days. Patients were asked to fill in a cough score and validated Leicester cough questionnaire (LCQ). RESULTS: 62 patients (75.6%) had completed the trial and no adverse effects were reported. Both intervened and control groups had improved in cough score and LCQ in the follow-up period, despite no overall statistical significance was observed in the differences of scores between the two groups. Women taking TCM had significantly fewer problems with sputum production (p = 0.03) and older subjects (>35 years of age) reported a significant improvement in hoarseness (p = 0.05) when compared to those using placebo. CONCLUSION: TCM was well-tolerated and received among the Hong Kong Chinese population. This TCM preparation appeared to have some benefits in the treatment of cough. Future research on TCM should concentrate more on commonly encountered conditions such as UTRI and cough. Our experience on the sensitivity of assessment tools used in detecting subtle differences in an otherwise self-limiting illness and clinical trial methodology when applying the underlying theory of how TCM works in disease management was invaluable
