M capsules are applied to treat NPC after radiotherapy. In comparision with 28 NPC patients who are do not use M capsules we have some remarks: the number of white blood cells, lymphocytes and lymphocyte subset increase faster and remain more stable, and there is a decrease of IgA/VCA titre lower and more stable in patients who used M capsules in comparision with those in the control group. In the using M capsules group we find that the number of patients who survive over three years increase as well as the metastasis rate. This result shows that M capsule might have effecting rising the number of white blood cells in NPC patients who got treated radiotherapy, and help lasting the life of the NPC patients.

Studying the dynamy of immunobiological parameters after radiotherapy and estimating its prognostic values on 77 NPC patients with T1-3No-3Mo (UICC 1979) at Hanoi K hospital from 11/1994 to 12/1998. We have some results: The prognostic values have been found significantly in the quantity of leukocytes, the level of serum IgA/VCA, IgG/EBNA before radiotherapy, the frequency of HLA antigens A11, A2, B17 and the desequilibre linkage A11-B17, A2-B17. Especially, the increase of serum IgA/VCA after radiotherapy has significantly predicted recurrence of studied NPC patients

Background: Limitation of daily activities is the obstacle that prevents the elderly from achieving their desires. Objective: Aim to discover the prevalence and risk factors of the limitation in daily activities in the elderly. Subject and methods: This cross - sectional study was conducted in 4 provinces: Thai Nguyen, Ha Tay, Hue and Can Tho during June to December 2006 among 2.644 people at the age of 60 and above. Results: The overall prevalence of limitation of the elderly is 5.6%, and 4.3% is totally dependent and 1.3% is partly dependent. This proportion increases with age. It happens more in urban areas as opposed to rural and mountainous areas. Those living with their spouse have lower proportion of limitations. Can Tho and Ha Tay has the higher proportion of limitation than Hue and Thai Nguyen. Factors related to these limitations are aging (OR = 1.08; 1.06-1.10), not working at the current time (OR = 0.11; 0.05-0.28), ethnicity (OR = 2.25; 1.45-3.49), lack of physical exercise (OR = 2.24, 1.75-3.85), brain damage (OR = 15.18; 9.47-24.35), dementia (OR = 2.39; 1.62-3.54) and loss of vision (OR =1.32; 1.05-1.65). Conclusion: The limitation in daily activities tremendously affects the quality of life for the elderly. Age, working status, race, physical activity, accident of cerebral vessels, dementia and vision loss are statistic significant related factors for the limitation in daily activities of the elderly

Background: Open heart surgery with cardiopulmonary bypass (CPB) causes haemostatic abnormalities which result in postoperative excessive bleeding. Objectives: To investigate haemostatic disorders before - after CPB and postoperative bleeding. Subjects and methods: Sixty congenital cardiac patients with and without cyanosis were recruited consecutively. Hematology and coagulation tests were done 1 day before operation, 15 minutes after protamine administration, 2 and 6 hours after the operation in the intensive care unit (lCU). Mediastinal chest tube drainage (MCTO) was measured for the first 6h in the ICU. Results: Significant differences between 2 groups could be found for red blood cells, hemoglobin, hematocrit, fibrinogen, D-dimer, fibrinogen degradation products (FOP), von Kaulla and platelet aggregation to epinephrine before operation (p < 0.05). There were not significant differences in platelets, PT, APTT, platelet aggregation to adenosine diphosphate (AOP) in the acyanotic and cyanotic patients (p > 0.05). Most hematology parameters were decreased significantly and hemostasis measurements were prolonged after operation in both groups (p < 0.05). There was also the significant difference in MCTO between 2 groups (p < 0.05). Conclusion: Coagulation, hemostasis and fibrinolysis disorders; thrombocytopenia and acquired transient platelet dysfunction may be responsible for bleeding complications after CBP \r\n', u'\r\n', u'

Background: Acute Respiratory Infection (ARI) is a common disease in developing countries. Morbidity and mortality of ARI are high, especially among children under 15 years old. Objectives: To describe socio-graphic factors, seasonal patterns, risky areas and determine the morbidity and mortality rates of acute respiratory infections in Thai Binh province. Subjects and method: This retrospective study reviewed the medical records of 4,585 hospital admitted patients who were diagnosed with ARI including upper and lower respiratory infections such as sore throat, pharyngitis, bronchitis, pneumonia and bronchitis-pneumonia at 8 district hospitals and 1 provincial hospital in Thai Binh province during 2002-2005. The selected medical records were based on the available check list and two standard screening tests. Results:Morbidity and mortality of ARI in Thai Binh province were 61.6 and 0.52, respectively. ARI mainly occurred among children under 5 years old, of which the highest mortality was among those under 12 months of age. Male children were at higher risk of acquiring ARI, but less prone to death than female. Occupation did not significantly associate with the risk of ARI. The morbidity increased sharply during inter-season, e.g. March and October. Thai Binh city, Kien Xuong and Tien Hai district were reported with the highest morbidity in accompany of the high mortality as consequences. Conclusion: The prevention and control methods were recommended to annually focus on the male children aged less than 5 years old during March and October in Thai Binh city, Kien Xuong and Tien Hai district.

Background: HIV/AIDS pandemic really become danger to mankind on the earth. Objectives: Description epidemiological characteristics of HIV/AIDS patients. Studying clinical expression, learning aboutdemands of infected patients and community care for infected patients. Subjects and method: 71 HIV/AIDS people in Thua Thien Hue were studied in 2006. Using descriptive method to give epidemiological characteristics and behaviour of HIV/AIDS people. People were determined HIV/AIDS infection based on the criteria of Ministry of Health. The information were collected by target study. Results: HIV/AIDS people mainly from the age of 20 to 39 (83,10%), males were 52,10% and in various levels of education and all kinds of occupation. The rate of sexually transmitted infection was 84,5% and infection transmission was 15,5%. The rate of sexually transmitted infection within the last 12 months was 57,7%. 63,4% of infected people used condom while having sex with their spouses or partners. 1,4% of infected people using drug infection within the last month. 38% of the infected people had manifestations of AIDS, 77,8% of HIV/AIDS were treated with antiviral drugs. Families and communities had positive attitudes and behaviors to the HIV/AIDS people. Infected people being remoted from the society was 12,7%, 88,7% of them receiving supports from their communities such as disease treatment, spirit and material supports and job opportunities. Conclusion: Strengthen communication activities to change behavior of HIV/AIDS people and in communitiy to reduce alienation, discrimination for infected people. Execute socialization in care and support for HIV/AIDS people.
