1.Study of cholera epidemic and cholera surveillance system at Hai Phong city
Journal of Preventive Medicine 1998;8(3):23-29
To confirm whether cholera epidemic in Hai Phong city is current or invasive, the stool samples from old cholera cases, healthy people, acute diarrhea cases as well as samples from environment such as oyster, fish, mussel etc. were collected for isolating V.cholerae 01. Not any of them was positive with V.cholera 01. It means that there was no evidence of current cholera epidemic in Hai Phong. The new cholera surveillance system was proposed for Hai Phong city.

2.Nosocomial pneumonia in patients with artificial ventilations
Journal of Preventive Medicine 2002;12(4):47-50
Nosocomial pneumonia is associated with increases in health care costs, morbidity and mortality. Data from our study in Bach Mai Hospital in 90 patients admitted to intensive care units from 1999 to 2001 indicate that, approximately 86% of patients got nosocomial infections. Gram(-) organisms were predominant (76%) with P.aeruginosa 57.3%; S.aureus 10.7%; Enterobacter 7.7%; Acinetobacter 6.8%. Almost these gram(-) becterial isolates were sensitive to imipenem (95.7%) and amikacin (87.8%).

Background: Burn patients are at high risk of occasional infection because microorganism can penetrate through the wound easily. Objective: To identify bacteria species that most often cause occasional infections in burn patients and evaluate the rate of resistance to antibiotics of the isolated bacteria species. Subject and Method: A cross-sectional study was carried out on 126 patients treated at the National Institute of Burns from 4/2007 to 3/2008. Result: Rates of bacteria species were Pseudomonas aeruginosa (45.98%), after that was S.aureus (25.29%); Abaumannii (9.2%); E.coli (3.45%) and Kpneunwniae (2.87%). Rate ofresistance to antibiotics of P.aeruginosa among aminoglycoside ranged from 22.54% to 80.56%; quinolone from 39.44% to 41.1%; Cephems from 68.49% to 80.56% and penicillin from 67.61% to 78.87%; Imipenem was 27.4%. Anti-biotics resistance of Abaumannii among aminoglycoside ranged from aminoglycoside from 25.0% to 87.5%; quinolone was 81.25%; cephems was 93.33% and penicillin was 86.67%; lmipenem was 50% and Aztreonam was 93.75%. S.aureus were sensitive to Vancomycin was 1000%, but resistant to lmipenem (72.73); Gentamicin (71.43); Kanamycin (83.33); Tobramycin (83.33%); Ticarcillin / Clavulanic acid (75.61%) and Ceftazidine (75.61%).Conclusion: Isolated bacteria species, which caused occasional infections in burn patients, are mainly P.aeruginosa, S.aureus and A.baumannii. Those species resist many kinds of antibiotic.\r\n', u'\r\n', u'

Objectives: To learn about the status of multidrug resistance in ubiquitous and dominant pseudomonas aeruginosa in Ha Noi hospital. Subjects and method: 138nosocomial Pseudomonas aerug.\r\n', u'Results:114 nosocomial Pseudomonas aerug- inosa isolates from Hanoi hospital were studied in relation to their antibiotic susceptibilities and the results showed the ratesof resistance to antibiotics among beta lactams ranged from 29 to 41.7%; quinolones ranged from 45.7% to 47.3%; cephems ranged from 64.1 % to 74.4% and aminoglyy cosides ranged from 41.1 to 74,6%. Of the five dominant serogroups O12 (27.2%); O11 (18.4%); O16 (11.4%); O5 (6.1%) and O2 (5.3%). Multidrug resistance rates in the major serogroups were O16 (100%); O11 (95.2%); and O12 (93.5%).Conclusion: Efforts to monitor antibiotic resistance of hospital bacteria strainsnationalwide, regional and local levels is necessary to provide physicians with the selection of information for effective treatment. \r\n', u'\r\n', u'

Background: Hypertensive with impaired fasting glucose is the basic expression of metabolic syndrome. Objectives: To study the IR and the correlation between Fasting Plasma Insulin (FPI) and Fasting Plasma Glucose (FPG) concentration in hypertensive patients with Impaired Fasting Glucose (IFG). Subjects and method: The descriptive, cross-sectional study was carried out on 38 hypertensive patients with IFG (IFG group) and 30 hypertensive patients without IFG (control group). The data were collected and analyzed by SPSS 11.5 software.

Background: In the past decades, preventive medicine had achieved significant success by promoting the effective prevention. However, we were facing with the rising again of dangerous infectious diseases that had been controlled. Ministry of Health had approved the development support project for preventive medicine system to strengthen early detection and control diseases in time. Objectives: To survey the manpower and the demand for training in basic microbiology technique of Centres for preventive medicine. Subjects and method: Technicians of 29 centres for preventive medicine in North provinces were surveyed and the results were studied by the described cross method. Results: Number of technicians graduated difference, fluctuated from 3 to 14 person per unit. The women were 80.4%; men were 19.6%. The staff who have degrees of postgraduate was 5.3%; University graduated was 41.2%; middle-ranking was 53.6%. Their specialities were very different: medicine doctor was 15.2%; biologists were 8.8%. The rest were nurse, technicians convalesce nurse, Medical Public Health...(34.4%). Among the demand for obtain the train in Microbiology, basic and advance labiratory techniques, 19.4% were the requests for training in basic microbiology; 16.4% were for molecular technology; 21.4% were for bacterium isolate technology and 19.4% were for virus technology. Conclusion: The results were the basis of creating a appropriate technical training strategy to contribute to the success of the project.

Despite their being uncommon, severe cutaneous adverse drug reactions (SCARs) result in a very great burden of disease. These reactions not only carry with them a high mortality (10%–50%) and high morbidity (60%) with severe ocular complications, alopecia, oral and dental complications and development of autoimmune diseases, but also create a substantial economic burden for patients' families and society. SCARs are, therefore, an important medical problem needing a solution in many countries, especially in Asia. The clinical spectrum of SCARs comprises Stevens-Johnson syndrome, toxic epidermal necrolysis, DRESS (drug rash with eosinophilia and systemic symptoms) (also known as drug hypersensitivity syndrome or drug-induced hypersensitivity syndrome) and acute generalised exanthematous pustulosis. Recent crucial advances in determining genetic susceptibility and understanding how T cells recognise certain medications or their metabolites via the major histocompatibility complex and the effects of cofactors, have led to the implementation of cost-effective screening programs enabling prevention in a number of countries, and to further understanding of the patho-mechanisms involved in SCARs and their significance. In this review, we document comprehensively the journey of SCARs from bedside to bench and outline future perspectives in SCARs research.
