Multicenter Study
Human leukocyte class I antigen alleles A2 and A11 are not associated with nasopharyngeal carcinoma in West Malaysia.
Nasopharyngeal carcinoma (NPC) is the second most common cancer among Malaysian Chinese males. We determined the frequencies of 17 human leukocyte antigens (HLA), HLA-A and HLA-B, alleles in 88 Malaysian Chinese with NPC. ⋯ We conclude that A1 is very rare, and A2, A11, A31, A32, A33, B8, B13, B38, B39, B44, B46, B55, B58, B61 and B71 alleles have no associations with the occurrence of NPC in Malaysia, while allele B27 is negatively associated.

Informed consent is now accepted as the cornerstone of medical practice, with reasonable patient standards typically considered to be appropriate in the developed countries; however it is still challenged in many developing countries. The objective of this descriptive study was to evaluate the perceptions and practices among attending medical professionals in matters relating to informed consent in selected hospitals. ⋯ Despite a very high awareness of informed consent, the model chosen reflected age-old medical paternalism. Doctors' opinions are accorded a larger role in clinical decision-making in Kashmir. The results emphasise the need for doctors to change their attitude and acknowledge the patient's autonomy, which is the basis of modern medical ethics, and yet still be aware of the cultural and religious views of the local population.

Randomized Controlled Trial Multicenter Study Comparative Study
Efficacy and tolerability of celecoxib compared with diclofenac slow release in the treatment of acute ankle sprain in an Asian population.
Cyclooxygenase (COX)-2 selective inhibitors are attractive candidates for treatment of ankle sprain because of their efficacy as anti-inflammatory and analgesic agents and their overall safety, including lack of effect on platelet aggregation. The objective of this study was to assess the efficacy and tolerability of celecoxib compared with diclofenac slow release (SR) in the treatment of acute ankle sprain in an Asian population. ⋯ Celecoxib, a COX-2 selective inhibitor, is as effective as diclofenac SR in treating ankle sprains. With its platelet-sparing properties, celecoxib may offer an advantage over diclofenac SR in managing musculoskeletal injuries.

Multicenter Study
A window on the current status of diabetes mellitus in Singapore--the Diabcare-Singapore 1998 study.
The Diabcare-Singapore project was carried out in 22 clinics (general hospitals, GH and primary healthcare centres, PHC) to provide an overview of diabetes management and metabolic control status. Data from 1697 diabetic patients were collected on paper forms and analysed centrally. Type 2 diabetes mellitus patients constituted 91.4% and type I patients constituted 8.1% of population. ⋯ Sixteen percent of patients had abnormal levels of protein (>500 mg/24 h) in the urine, 3% had elevated serum creatinine levels and 36% had microalbuminuria. Retinopathy (12%), cataract (16%) and neuropathy (12%) were commonly reported diabetic complications. The data revealed suboptimal glycaemic control in about half of patients studied.
