Background: Wrist joint damage is early, common symptom and in diagnostic criteria of rheumatoid arthritis. Objective: to describe characteristics of MRI of the wrist in rheumatoid arthritis. Subjects and methods: This was a describe study. The study included 41 patients who were diagnosed rheumatoid arthritis according to the criteria of American College of Rheumatology- 1987 from January to October - 2006. Results: The average disease duration was 16.4 \xb114.71months. According to Rheumatoid Arthritis Magnetic Resonance Imaging Score (RAMRIS) 2002, damages on MRI included: 100% of patients had synovitis (5.9 \xb1 2.20), 100% of patients had bone erosions (15.3 \xb1 11.06) and 90% of patients had bone edema (7.3 \xb1 5.86), total score 28.6 \xb1 16.58. The correlative coefficient between synovitis and bone edema: r=0.43, P<0.01, between synovitis and bone erosions:r=0.61, P<0.01, between bone erosions and bone edema: r=0.55, P<0.01. MRI revealed bone erosions in 100% of patients having rheumatoid arthritis less six months after symptom onset compared with 0% of patients on radiography. In patients with over 2 years of disease duration, this rate on MRI was 100% of patients compared with 87.5% of patients on radiography. Conclusions: The specific damages of the wrist on MRI have value in diagnosis of early rheumatoid arthritis. \r\n', u'\r\n', u'\r\n', u'

In this report we describe a new approach in HIV sentinel surveillance that was piloted in Viet Nam in 2009 and is currently being rolled out in all provinces. It comprises a brief behavioural questionnaire added to the HIV sentinel surveillance surveys conducted routinely among people who inject drugs, female sex workers and men who have sex with men. Timely reporting of data from this system has resulted in improvements to HIV prevention efforts for most at-risk populations.

This paper describes progress on formulating a national asbestos profile for the country of Vietnam. The Center of Asbestos Resource, Vietnam, formulated a National Profile on Asbestos-related Occupational Health, with due reference to the International Labor Organization/World Health Organization National Asbestos Profile. The Center of Asbestos Resource was established by the Vietnamese Health Environment Management Agency and the National Institute of Labor Protection, with the support of the Australian Agency for International Development, as a coordinating point for asbestos-related issues in Vietnam. Under the National Profile on Asbestos-related Occupational Health framework, the Center of Asbestos Resource succeeded in compiling relevant information for 15 of the 18 designated items outlined in the International Labor Organization/World Health Organization National Asbestos Profile, some overlaps of the information items notwithstanding. Today, Vietnam continues to import and use an average of more than 60,000 metric tons of raw asbestos per year. Information on asbestos-related diseases is limited, but the country has begun to diagnose mesothelioma cases, with the technical cooperation of Japan. As it stands, the National Profile on Asbestos-related Occupational Health needs further work and updating. However, we envisage that the National Profile on Asbestos-related Occupational Health will ultimately facilitate the smooth transition to an asbestos-free Vietnam.
