30 patients aged 18-60 years old with melasma localized at the epiderm and epiderm plus mesoderm layer topically treated by 2% hydroquinone preparation within 6 months at the Venero-dermatol Institute were evaluated. Good and very good results reached in 42.5%. The size of lesion minimized by > 10% each months, especially 21% in the 2nd month. Mean size of lesion minimized by 75%. In 11.2% of patients, the size of lesion minimized by 90-100% and 56.3% of patients had got the lesion of 70-89% minimized size.

1667 laborers were interviewed on using the plant protective chemicals in 16 communes of 8 provinces: §ång Nai, L©m §ång, TiÒn Giang, B×nh D­¬ng, B×nh Ph­íc, Ninh ThuËn, B×nh ThuËn, Kh¸nh Hßa in year 2000. Results: 100% or farm households were using plant protective chemicals. Number and types of plant protective chemicals used are various. The management of plant protective chemicals remained to be not tightly. They are used unsafe and inappropriately, cause effects on the laborer health and toxicity. The incidence of Tb toxicosis is 22.92 per 10,000 people. The incidence of Padan toxicosis is highest.

Objective: The purpose of this survey was to estimate the prevalence of viral load (VL) suppression and emergence of HIV drug resistance (HIVDR) among individuals receiving antiretroviral therapy (ART) for 36 months or longer in Viet Nam using a nationally representative sampling method. Methods: The survey was conducted between May and August 2014 using a two-stage cluster design. Sixteen ART clinics were selected using probability proportional to proxy size sampling, and patients receiving ART for at least 36 months were consecutively enrolled. Epidemiological information and blood specimens were collected for HIV-1 VL and HIVDR testing; HIVDR was defined by the Stanford University HIVDR algorithm. Results: Overall, 365 eligible individuals were recruited with a mean age of 38.2 years; 68.4% were men. The mean time on ART was 75.5 months (95% confidence interval [CI]: 69.0–81.9 months), and 93.7% of the patients were receiving non-nucleoside reverse transcriptase inhibitor-based regimens. Of the 365 individuals, 345 (94.7%, 95% CI: 64.1–99.4%) had VL below 1000 copies/mL and 19 (4.6%, 95% CI: 2.8-–7.5) had HIVDR mutations. Discussion Our nationally representative survey found a high level of VL suppression and a low prevalence of HIVDR among individuals who received ART for at least 36 months in Viet Nam. Continued surveillance for HIVDR is important for evaluating and improving HIV programs.
