Helicobacter pylori-negative gastric mucosa-associated lymphoid tissue lymphoma: magnifying endoscopy findings

Gastric mucosaâ associated lymphoid tissue lymphoma is uncommon and most patients have an indolent clinical course. The clinical presentation and endoscopic findings can be subtle and diagnosis can be missed on white light endoscopy. Magnifying endoscopy may help identify the abnormal microstructural and microvascular patterns, and target biopsies can be performed. We describe herein the case of a 64-year-old woman with Helicobacter pyloriâ negative gastric mucosaâ associated lymphoid tissue lymphoma diagnosed by screening magnification endoscopy. Helicobacter pyloriâ eradication therapy was given and she received biological therapy. She is in clinical remission after treatment. The use of magnification endoscopy in gastric mucosaâ associated lymphoid tissue lymphoma and its management are reviewed.published_or_final_versio

Use of the International Prostate Symptom Score (IPSS) in Chinese male patients with benign prostatic hyperplasia

Purpose: To test the psychometric properties of the International Prostate Symptom Score (Hong Kong Chinese version 2) (IPSS) in Chinese male patients with benign prostatic hyperplasia (BPH) under secondary care. Methods: A prospective longitudinal study was done by interviewing subjects at baseline, at 2 week after baseline for assessing test–retest reliability and at 26 week after baseline for assessing responsiveness. All subjects were interviewed to complete a structured questionnaire including IPSS, Short Form-12 Health Survey version 2 (SF-12v2) and Depression Anxiety Stress Scale (DASS). Results: The IPSS HRQOL score had weak correlations with SF-12v2 summary and DASS domain scores. For reliability analysis, Cronbach’s alpha coefficient was 0.90 for the seven symptom-related items. The intraclass correlation coefficients of the IPSS total symptom score and HRQOL score were 0.90 and 0.86, respectively. For sensitivity, statistically significant differences were detected between the subjects with BPH and those without for IPSS total symptom score (effect size=0.68) but not the IPSS HRQOL score. The areas under ROC curves for the IPSS total symptom and HRQOL scores were 0.67 and 0.60, respectively. Conclusions: The IPSS was valid, reliable instrument in Chinese patients with BPH. The IPSS total symptom score, but not the HRQOL score, is sensitive in differentiating subgroups

Coastal ecotourism and industrial impacts on Indo-Pacific humpback dolphins in Hong Kong

Conference Theme: Conservation of Marine Mammals: Science Making a DifferenceOne of the largest populations of the Indo-Pacific humpback dolphin (Sousa chinensis) resides in the Pearl River Delta (PRD) area. The coastal affinity of this species makes them particularly exposed to coastal tourism and industrial activities. Recently, the PRD area in Hong Kong has experienced a rapid increase in coastal development projects, leaving limited natural habitats available to the dolphins in the area. A recent population trend projection, suggesting a significant decline in numbers of the PRD animals, has heightened the conservation concern. This study investigated movement patterns of humpback dolphins observed from strategic land-based platforms in areas designated as high importance to the species. Analyses of theodolite-obtained data evaluated movement (e.g. directionality, re-orientation, speed, etc.); focal behavioural events and behavioural states of the dolphins to understand their 'natural' habitat use in these important areas as well as movement and behavioural response indicators relative to unregulated dolphin-watch tourism and industrial anthropogenic activities. Spatiotemporal patterns in dolphin abundance/distribution, movements, and habitat preference were also compared among the different study sites to determine difference in areas with and without high anthropogenic activities. Spatial explicit and uncorrelated random walk models were used to provide quantitative information about individual/group movement/response patterns. Geographic occurrence of dolphins relative to different anthropogenic activities in the different study sites were analysed using ESRI ArcMap GIS. Type and intensity of anthropogenic activities can directly affect the individual and population fitness. The results of this study provide local conservationists and managers with valuable feedback on ecotourism management and impact concerns of industrial development as well as much needed biological monitoring and implementation of mitigations measures to protect the humpback dolphins that depend year-round on the PRD coastal habitat.link_to_OA_fulltex

Concomitant use of Western and Chinese medicine treatments in neurosurgical patients in Hong Kong

Objective: To investigate the profile of concomitant use of Chinese medicine (CM) and Western medical treatment in neurosurgical patients. Methods: A guided questionnaire survey was conducted on 309 Chinese patients under neurosurgical care in a teaching hospital in Hong Kong from June to July 2006. Results: Concomitant use of CM was reported by 25.9% of patients. Age was identified to be associated with the use of CM. Half of the CM-users were unaware of there being potential risks of adverse interactions between neurosurgical and CM treatments. Among the CM-users 85% would continue to receive both treatments but only 52.0% would inform neurosurgeons on their CM use. Patients' perceived lack of benefit from CM was the main reason for not using it although 47.0% indicated their willingness to try CM given better access to information. Conclusions: Informal source was the major channel of CM use amongst patients with neurosurgical conditions. A need for improved patient education and service provision was identified and should become an important consideration for healthcare systems which anticipate an increased use of CM amongst patients. Strategies to enhance doctor-patient communications in mainstream care such as pre-operative checklists for herbal medications and post-operative advice may facilitate the safe and complementary use of both treatment systems. © 2011 Chinese Association of the Integration of Traditional and Western Medicine and Springer-Verlag Berlin Heidelberg.link_to_subscribed_fulltex
