Fifty three of normogravid - normotensive women who subsequently developed pregnancy - included hypertension demonstrated an increase in diastolic blood pressure at least 20 mmHg when turned from the lateral recumbent to the supine position, between twenty eight and thirty six weeks of gestation. Conversely 95.8% percent of women who did not demonstrate such a rise in diastolic blood pressure when turned to supine position did not become hypertensive during that pregnancy. The results demonstrated the high validity of this method as follow: the sensivity of predictive value: 65%. The specificity of predictive value: 93%, the positive predictive value: 53%, the negative predictive value: 96%.

In the first 7 months of 2002, the malaria status in Bac Can province were rather stable: the malaria incidence reduced 16%, there was no malaria outbreak, the morbidity due to malaria reduced. These activities to practice the malaria prevention plan in Bac Can: supervising malaria epidemiology, preventing vecto, propagating healthy education, educating training, systemizing report information, using materials expenses. The result of survey quality malaria prevention activities in Cho Moi and Mach Thong districts were low: Bach Thong district examined newly supplement smear pills, in which smear pill had more mistakes; Cho Moi district treated correctly 50% of checked case history

Blood screening voluntary donor in HCMC. We investigated 47,621 samples of blood. Results: HbsAg (+): 7.15%, antiHCV: 3.11%, anti HIV: 0.29; VDRL (+) 1.08%, Malaria (+): 0.27%; abnormal antibodies: 0.20%.

203 products of total blood and 203 products of the erythroprecipitin undergone the quality control during 1/200-27/9/2000. The results have shown that the blood volume of 4.92% products was lower than 250 ml and level of hemoglobin of 1% products was lower than 22g among 203 controlled products of the total blood; volume of 2.11% products was less than 125ml and of 12.67% products was more than 125 ml; the level of hemoglobin of 100% products was higher than 22 g and of 80% products was higher than 25g, the hematocrite of 4.22% products was higher than 0.75 l/l among 142 controlled products of the erythroprecipitin. The conclusion: products, in generally obtained the ISO 9002.

We performed 10 cases of autologous peripheral blood stem cell transplantation without cryoprevervation in 11/1996 and 12/1997 12. Patients were diagnosed of AML, ALL, CML and non Hodgkin’s lymphoma. The median age of the patients was 34 years (range 18-43). Peripheral blood stem cell mobilizing regiments consisted of Daunorubicine (50 mg/ m2/d, d1-d5) cytarabine and etoposide in 3 CML patients and high dose cyclophosphamide in the seven other patients, followed by G-CSF starting when an ANC< 0.5x 109/l until the day before the last leukapheresis. When a WBC count reached 4x109/l leukapheresis was started and continued for 3 consecutive days, as soon as the third collection was finished Melphalan was given as a conditioning regimen, 42 hours after giving Melphalan, the collected PSCs which were preserved at +40C (90 hours after giving Melphalan, the collected PSCs which were preserved at + 40C were reinfused through a central Hickman’s catheter. GM-CSF was given during the nadir period until the an ANC > 1x109/l for 3 consecutive days. The median number of mononucleated cells and CD34+ cell were 5x108/kg respectively. All platelet count > 20 x 109/l was 13 days and 20 days following transplantation, all patients are still in CR and alive with the median follow-up of 8 months.

The study was carried out on 98 patients who needed to be transfused regularly. Phenotyped red blood cells of groups were used for this purpose. Only immunogenic antigens of the common blood groups were included in this study, such as Rh, MNSs, Duffy and Kidd systems. The highest quantity of units transfused depassed the number 44. After a period of thirteen months, there was no antibody detected. But in the other hand, we found 4 cases of immune antibodies in patients who previously received multiply transfusions of non phenotyped blood. These antibodies belong to Rh, Duffy and Kidd systems which are highly immunogenic. These results showed the need and importance of performing adequate compatibility testing for multiply transfused patients and the benefit of using phenotyped blood for those who need regular transfusions.

The blood transfusion is necessary while the donor’s marrow has not been growed yet. The transfused blood products must assure completely the safety principles for disease transmission, the blood products is not infected the MCV and removed the leucocyte usually transfused after 4- 12 weeks of transplantation with the suitable dosage for individuals. Condensed platalet is transfused after 6-12 weeks of transplantation. It should maintain the amount of thrombocyte in the peripheral blood within 50-100x109/lit, the dose is different from one patient to another.

The bone marrow transplantation is a most modern technique and applied in Vietnam to treat the malignant hematological diseases. This paper introduced the bone marrow heterotransplantation and the autologous peripheral blood stem cell transplantation. 3 patients (1 male; 2 female) received transplantation (bone marrow fluid was extracted from patient’s brothers) for the treatment of the chronic myeloid leukemia and severe thalassemia and 17 patients received the autologous peripheral blood stem cell transplantation for treatment of acute myeloid leukemia, chronic myeloid leukemia, acute lyphoid leukemia and lymphoma. The results have shown that the longest survival duration was 42 months after the autologous peripheral blood stem cell transplantation. The patients had a normal life such as learning, working and social activities. After 2 months of transplantation, the average disease free duration of 10 patients with AML and 6 patients with ALL were 27 months, and 30-40 months, respectively. This was an great encouragement.

Results of studying in 4 districts of Ninh Binh city in June 1998 showed that the morbidity rate in people over 60 year olds was highest, followed by groups of children under 1 year and 5 year. Female morbidity rate was higher than this in male, especially the women at ages of 16-59 (5.4% compared with 2.9%). The average frequency of incidence estimated 92 times/100 inhabitants/year (0.9 generally and 0.8 for male; 1.0 for female). The 3 common diseases were the central nervous syndromes, the chronic respiration diseases, and bone and joint pain.

Center for the trauma and orthopady treated 200 cases of foot deformity in which 1,500 cases received operations. Most of them were congenital club foot (70%) followed by club food due to the polio fever(20%) due to the brain paralysis (5%) and due to arthrogrip ossis (5%). The orthopadic equipments were applied for 35 cases. The equipment was used within 5 weeks and continuously fixed by gypsum up to 3 months from the day of operation.
