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

To survey the basic measurements of urodynamic as cystometry, uroflowmetry, electromyography, urethral profilometry. Currently, it may be to combine measurements each other or urodynamic with image diagnostic technique in order to have comprehensive consideration, more accurate on lower urinary tract function: To combine with cystometry, uroflowmetry and electromyography, detrusor pressure measurement, to combine with cystometry and observe reflection of light of cystoids under fluorescent screen, video-urodynamics

Varicocele is a dilatation of plexus venosus in the spermatic cord. It rarely occurs before the age of puberty, but 15% of male teenager experienced varicocele (the rate is relatively high). This rate is higher when surveying data of male infertility (35% of primary infertility patients, and 75-81% of secondary infertility patients had experienced varicocele). Varicocele may affect both sides, but 90% of cases occurred in 1 side and among them 90% were in the left side. Microsurgery is a treatment with high rate of success

Study of 6 peripheral channels of ECG in 62 children of the ages 9, 12, 14 showed that the heart frequency decreases with increasing age. In a same age, the frequency is higher in girl than in boy. Alpha angle valne decreases with increasing age. The electrocardiogram axis trends to move from right to left side, in contrary with the clock hand movement. Average duration of wave depends on the heart frequency. The altitude of wave of these three age groups has not significant difference

A study on hypertension in 548 officials of Thanh Nhan hospital from May 2001 to July 2001 showed that there were 56 officials suffered from hypertension (10,22%); the rate of hypertension in males was higher than in females, the rate increased with age, especially people over 50 years. Risk factors for hypertension: elderly, intellectual work, having relatives with hypertension, lack of physical exercise, sleeplessness, salty diet, drink, smoking. Common complications in 56 hypertensive patients were: 55,36% increased total cholesterol, 53,57% increased triglyceride, 7,14% increased uremia, rhythm disturbances 17,86%, left ventricular hypertrophy 19,64%, swelled arteries 14,29%, congested 16,07%, hemorrhaged 10,71%, swelled yellow spot 12,5%

Investigation on 100 patients aged over 50, treated at cardiology department of Thanh Nhan hospital from January to December 2001 showed that: Heart failure was common in cardiovascular diseases (14.6%). The incident of heart failure increased with age, more in females than in males. The common causes of heart failure were valvular diseases (37%), hypertension (31%), myocardial ischemia (17%)… The majority of patients with heart failure hospitalized were in severe situation (third degree: 51%, fourth degree: 10%). Besides diuretic and Digoxin, most patients must use the angiotensin converting enzyme (ACE) inhibitor, other used β blockers

151 pediatric patients of 1-60 month age with bronchitis pneumonia at Hanoi Thanh Nhan Hospital were enrolled into study from November 2001 to September 2002. Most of patients were suffering from cough, fever,dyspnoea,mental disorder, digestive disorder, rale murmure, increase of neutrophile, bacteria positive culture in 29,14% of cases. Common bacteria were H.influenza- 39,58%, S.pneumonia – 35,42%, S. pyogenes -14,58%, S. aureus – 6,25%. In male the incidence was 63,58%, higher considerably than in female and the incidence increased progressively with age. In rural population, the incidence (31,86) was higher than in urban (25,39%). Pneumonia which associated with other pathology accounted for 81,46%, usually upper respiratory tract – 80,82%, malnourished – 36,92%, diarrhoea – 12,05%; and other conditions such as congenital defect, rickets, varicella, erythema...

In 2002-2003 year period at HCM City Blood Transfusion and Hematology 8 cases of umbilical cord blood transplantation were performed.including 2 cases of lymphoid acute leukemia, 3 cases of myeloid acute leukemia, 3 cases of beta thalassemia. Among them, there were a case of HLA- identical blood and 7 cases of HLA-dismatched blood. After 36 months, 61,90% of cases were recovered survivals and after 24 months 71,43%
