Background: Piperaquin (PQ) is an anti-malaria drug, which belong to bisquinoline class. Vietnam has successfully produced PQ (both base and phosphate) since 2004. Objective: To evaluate acute oral toxicities of Piperaquine phosphate and the fixed combination anti-malarial drug Dihydroartemisinin plus Piperaquine in mice. Subject and Method: This study was conducted at National Institute of Malariology, Parasitology and Entomology between June and October, 2005. The acute oral toxicities of piperaquine phosphate (PQP) and the fixed combination anti-malaria drug (40 mg dihydroiutemisinin plus 320 mg piperaquine phosphate (DHA-PQP), with the materials produced by Institute of chemistry) in mice were investigated. Result: PQP had a medium toxicity. Inhibition of mice's central nervous systems was the main toxicity exhibition. At the high doses of PQP, mice's convulsion was observed before their deaths. The infralethal dose (LDo), absolute lethal dose (LD100) and mean lethal dose (LD50) of PQP were 900, 2300 and 1643.98 (1537.6 \u2013 1758.92) mg/kg, respectively. The fixed combination DHA-PQP had a less toxicity than PQP powder, with LDo, LD100 and LD50 were 1400, 2800 and 2050.06 (1943.63 \u2013 2157.14) mg per kg of body weight, respectively. Conclusion: At the high doses of DHA-PQP, this combination also inhibited mice's central nervous systems. Mice convulsed strongly before their deaths. All died mice were operated for observing visually their organs such as hearts, livers, kidneys, lungs, vesicles and intestines. No abnormal signals were found.

INTRODUCTION: Extensively drug-resistant tuberculosis (XDR-TB) represents an emerging public health problem worldwide. According to the World Health Organization, an estimated 9.7% of multidrug-resistant TB (MDR-TB) cases are defined as XDR-TB globally. The objective of this study was to determine the prevalence of drug resistance to second-line TB drugs among MDR-TB cases detected in the Fourth National Anti-Tuberculosis Drug Resistance Survey in Viet Nam. METHODS: Eighty clusters of TB cases were selected using a probability-proportion-to-size approach. To identify MDR-TB cases, drug susceptibility testing (DST) was performed for the four major first-line TB drugs. DST of second-line drugs (ofloxacin, amikacin, kanamycin, capreomycin) was performed on isolates from MDR-TB cases to identify pre-XDR and XDR cases. RESULTS: A total of 1629 smear-positive TB cases were eligible for culture and DST. Of those, DST results for first-line drugs were available for 1312 cases, and 91 (6.9%) had MDR-TB. Second-line DST results were available for 84 of these cases. Of those, 15 cases (17.9%) had ofloxacin resistance and 6.0% were resistant to kanamycin and capreomycin. Five MDR-TB cases (6.0%) met the criteria of XDR-TB. CONCLUSION: This survey provides the first estimates of the proportion of XDR-TB among MDR-TB cases in Viet Nam and provides important information for local policies regarding second-line DST. Local policies and programmes that are geared towards TB prevention, early diagnosis and treatment with effective regimens are of high importance.

Background: The combination of dihydroartemisinin and piperaquine is interested because of its efficiency and safety in treating malaria. Objective: To evaluate the influences of the fixed combination anti-malarial drug dihydroartemisinin plus piperaquine in constitutions and some biochemical and haematological indices of rabbits. Subject and Method: The sub-chronic toxicity of the fixed combination anti-malarial drug of 40 mg dihydroartemisinin plus 320 mg piperaquine phosphate (DHA-PQP), with the materials produced by Institute of Chemistry, in rabbits was investigated. Rabbits were treated daily by oral route with DHA-PQP at the dose regimens of 64 and 100 mg/kg per day for 28 consecutive days. Result and Conclusion: DHA-PQP did not affect on rabbits' constitutions. Generally, all rabbits had normal ingestions, activities, and defecations. Rabbits' body weights increased regularly along the study period and significantly increased between day 28 and day 0 (P < 0.05). At the dose regimen of 64 mg/kg per day for 28 consecutive days, DHA-PQP did not change significantly rabbits' biochemical indices (including GOT, GPT, bilirubin, creatinine and protein) and haematological. These changes were insignificantly different between the treated and control groups at the same study points (P > 0.05). With the dose regimen of 100 mg/kg, the combination did not affect significantly (P>0.05) on some rabbits' biochemical and haematological indices. But hemoglobin, erythrocyte count and rate of monocytes increased significantly on day 14 comparing to that the control group (P < 0.05) and became in normal limits on day 29 (P > 0.05). Protein concentration also increased significantly on days 14 and 29 comparing to that of day 0 (P < 0.05).

Background: Cystic hygromas is a common abnormal event in obstetrics ultrasound, which is induced by a chromosome disorder; it is also one of the major causes inducing fetus\u2019s congenital malformation. Objective: Determining chromosomal aberration in nuchal cystic hygromas by FISH technique and outcomes the value of factors in prognosis fetuses with cystic hygroma. Subject and methods: 53 fetuses with cystic hygroma, which are detected by ultrasound scan, are analyzed by FISH technique. Compare results of FISH, band G chromosomal analysis, ultrasonographic abnormalities, followed the fetuses. Results: Chromosomal and FISH analysis give the same detection: abnormal chromosomes: 75.46%, the highest rate is Turner syndrome: 50.94%, normal chromosome: 24.53%. Abnormal chromosomal fetuses: multi-malformation, grim prognosis. Cystic hygroma with other malformation in scan: high rate chromosomal aberrations and septated hygroma, Turner syndrome fetuses have large cystic hygroma, 4/6 fetuses with normal chromosome and without other abnormal result scan have resolutions of hygroma in the second trimester, normal birth. Conclusions: Abnormal chromosomes: 75.46%. Prognosis is grim: abnormal chromosomes, other malformations in scan, large cystic, septated hygroma. Prognosis is better: normal chromosomes, without other ultrasonographic abnormalities, small cystic, nonseptated hygroma, resolution of cystic hygroma.

Health financing has been considered as an important building block of a health system and has a key role in promoting universal health coverage in the Vietnam. This paper aims to describe the pattern of health expenditure, including total health expenditure and composition of health expenditure, over the last two decades in Vietnam. The paper mainly uses the data from Vietnam National Health Account and Vietnam Living Standards Survey. We also included data from other relevant published literature, reports and statistics about health care expenditure in Vietnam. The per capita health expenditure in Vietnam increased from US$ 14 in 1995 to US$ 86 in 2012. The total health expenditure as a share of GDP also rose from 5.2% in 1995 to 6.9% in 2012. Public health expenditure as percentage of government expenditure rose from 7.4% in 1995 to nearly 10% in 2012. The coverage of health insurance went up from 10% in 1995 to 68.5% in 2012. However, health financing in Vietnam was depending on private expenditures (57.4% in 2012). As a result, the proportion of households with catastrophic expenditure in 2012 was 4.2%. The rate of impoverishment in 2012 was 2.5%. To ensure equity and efficient goal of health system, policy actions for containing the health care out-of-pocket payments and their poverty impacts are urgently needed in Vietnam.
