Background: Like other countries in the world, Vietnam has seen the appearance of many infectious diseases such as SARS, influenza A/H1N1. Therefore, monitoring and quick response to infectious diseases, increasingly require enhancing the capacity of test systems. \r\n', u'Objectives: To determine the capacity for microbiological diagnosis and etiology of communicable diseases at the provincial centers for preventive medicine.\r\n', u'Subjects and methods: With the application of the cross-sectional approach, the study was conducted on microbiology diagnostic capacity for communicable diseases surveillance and response system in 55 Provincial Preventive Medicine Centers (PPMCs)\r\n', u'Results: Laboratory testing and confirmation (isolation and bio-chemical tests, gram stain) are only available for common nitrobacteria such as Escherichia coli, Vibrio cholera, Shigella, Salmonella, and some of the respiratory bacteria as streptococcus, meningococcus, etc... in most PPMCs. ELISA/MACELISA technique for detecting virus pathogen such as Arbo viruses (Dengue, Japanese B encephalitis) and Hepatitis B, HIV is also a focus of these PPMCs. However, for diseases caused by other viruses like Polio, Rota, measles, influenza, PPMCs have only the ability to collect specimens. \r\n', u'Conclusions: Most of the cases reported in the surveillance reports are based on clinical signs, only. Case confirmation was done by hospital/regional or national laboratory. \r\n', u'\r\n', u'

Background: Patients who received multiple transfusions of blood and blood products may produce antibodies against antigens of erythrocytes, leukocytes, platelets etc, resulting in many clinical implications. Objectives: To detect frequencies of antineutrophil antibodies in multitransfused patients at National Institute of Hematology and Blood Transfusion (NIHBT). Subjects and methods: The study was conducted on 30 multitransfused patients. Among them there were 12 with thrombocytopenia and 18 with aplastic anemia. Results: 6 cases had anti - neutrophil antibodies, of which 5 had more than 5 times of transfusion, 4 with aplastic anemia and 2 with thrombocytopenia. The sera were further tested with neutrophil panel, revealing 4 samples with anti - NA 1 (13.3%) and 1 sample with anti - NA2 (3.3%). The frequency of anti - neutrophil antibodies in multitransfused patients at IHBT in the study is 20%. Conclusion: Frequency of anti-NA1 was higher than anti-NA2 in multitransfused patients at NIHBT and directly proportional by frequency of NA1 and NA2 antigens in this group. The technical process to identify and classify antineutrophil antibodies in this study can be applied for patients who received multiple transfusions of blood and blood products in Viet Nam

Background: The strategy of Integrated Management of Childhood Illness (IMCI) was developed as an approach/tool for reducing the childhood mortality in developing countries. IMCI was approved by the Ministry of Health of Viet Nam and has been implemented in more than 3500 communal health centers nationwide. Aims: 1) To discover the quality of health care services for children under-5 and the situation of IMCI in health facilities. 2) To propose solutions to improve the quality of health care services for children. Materials and method: The cross-sectional study using quantitative and qualitative approaches conducted 58 direct observations in health workers, interviewed 58 caretakers, comprehensively interviewed 20 local leaders and technical staffs, facilitated 12 focal group discussions and reviewed 120 records of 12 commune health centers. Results: IMCI was considered by all of the participants as a comprehensive approach to improving the quality of childhood health care at first-level health facilities. IMCI contributed towards improved case management skills of health workers, improved the supply of essential drugs and supplies for child health care. As a result, the quality of health services for children under-5 has been promoted (93% of illness children were correctly assessed and classified, 84.6% of them were correctly treated and counseled). Health workers in Ly Nhan district, Ha Nam province adhered to 8.4+/-1.5 out of 10 essential steps of comprehensive child health care. Contrarily, this indicator was low in the districts of Bac Giang province (4.8+/-1.5), not much different to untrained IMCI health workers. Conclusion: IMCI is a useful strategy to improving the quality of child health care. But there were some difficulties that affected the implementation of this strategy in first-level health facilities.

Background: Child health care practices in the context of households and community is an important factor to improving the health of children. Some indexes were proposed by the World Health Organization to evaluate these practices. Objectives: To describe the knowledge and practice of pregnant women, under-5-year-old children\u2019s health care and assess the application of the survey toolkit in evaluating various indexes of healthcare practice at family and community levels. Subjects and method: By employing a structured interview, this cross-sectional survey has been conducted in Tu Liem district - Hanoi city and Tien Hai district \u2013 Thai Binh province. 120 mothers of under-5-year-old children participated in the survey. Results:98% of mothers had at least 3 antenatal visits during pregnancy. The rate of complete tetanus vaccination reached 43.3% in Tu Liem and 65% in Tien Hai. Prevalence of infant with low birth weight for age accounted for 8.3% in both districts. The percentage of children given complementary feeding at age of 6 to 9 months as the National Nutrition Program recommendations was only 30%. 65.7% and 68.5% of under-2-year-old children in Tu Liem and Tien Hai were breastfed within the first 30 minutes after delivery. There were a small proportion of mothers who gave complementary food either too early or too late, 8.3% and 8.4% in Tu Liem, 6.7% and 6.6% in Tien Hai, respectively. More than 90% of children were given normal feeding as usual during last their illness, but only 50% of children were given more fluid than usual. 98.2% of mothers knew 2 signs to immediately bring the child to health facilities. The most common injuries in under-5-year-old children were animal bites (62.5%) and falling (31.3%), however only 62.5% of mothers knew at least two measures of injury prevention. Conclusion: The toolkit for collecting data of practical index assessment can be applied at communes.
