Between 1/1993-12/1996, 58 patients (48 males, 15 females) with haemorrhoids of grade 3 or 4 underwent Milligan-Morgan procedure in ViÖt §øc Hospital. Ages range from 29 to 70, with an average of 45 years. Most of these patients were operated on elective surgery, only some of them on emergency because of complications of haemorrhoids (thrombosis...). Post-operative measurements were favourable with 4 days of hospitalization in average. Good results were obtained in more than 94% of patients by 4 years of follow-up.

Fracture of the lateral Condyle of the Humerus in children accounted for 18.1% of total fractures of the regional elbow. During a 11 year-period, we operated 36 cases with fracture of the lateral Condyle of the Humerus. Our purpose is in papers: (1) determining diagnosis and classifying fracture of the lateral Condyle, (2) remark surgical technique and results. We used Kirschner wire for fixation of the fragment. We believe that a minium of two wires are necessary to prevent rotation. The fracture is usually sufficiently stable to allow wires removal by 6 to 12 weeks and to allow the patient to begin protected active range of motion of the elbow. The follow up that our results: good: 14; fair: 15; poor: 07. Complications (1) avascular necrosis of the condylar fragment: 02. (2) cubitus valgus: 05

The speed of development in antibiotics appears have not kept pace with that of development in antibiotic-resistant bacteria. The appropriate antibiotic regimens will cure diseases and prevent the antibiotic-resistant bacteria from development. 4 antibiotic regimens were used randomly, included 1) penicillin alone; 2) penicillin combined with gentamycine, 3) cephalosporine; and 4) chloramphenicol. Regimens 2 and 3 provided good effect in treatment of severe and very severe pneumonia caused by antibiotic-resistant bacteria in under 5-year children (the rate of cure is 66.7% and 72%, respectively). Regimens 1 and 4 provided less effect (30.8% and 29%, respectively

A study was carried out in pediatric patients with severe and very severe pneumonia in the pediatric department of Bach Mai hospital during 8/1994 – 3/1998. The children were divided in to 2 groups: Group I: Pneumonia due to the antibiotic resistance microbial. Group II: Pneumonia due to the antibiotic sensitivity microbial, the body temperature, breathing rhythm and number of leukocyte in the peripheral blood patients received penicillin + gentamicin; cephalosporin; penicillin; and chlorainphenicol. The results have shown that after 3 – 5 days of treatment with penicillin + cephalosporine, the body temperature and breathing rhythm become the normal level, the number of leukocytes reduced 15%. In contrary, in patients received single penicillin or chloramphenicol, these parameters has not become to the normal level; the number of leukocyte reduced less than 15%.

A study on the establishment of the effective standard for the national standard samples of vaccine of single vaccine type 1, 2 and 3 and triple vaccine (Sabin) produced in Vietnam was carried out. The sesults have shown that the National standard sample had a high unified and stable properties that meet the requirement of the world health organization (WHO). The National standard sample were used to evaluate the quality of sabin vaccine produced in Vietnam which showed that 450 batches (100%) sabin vaccine produced in the scientific center for the vaccine production during 1995-1999 obtained the standard of WHO.

A cross-sectional study of 204 hip radiographs of high risk CDH (Congenital Dislocation of the Hip) group newborn, using: (1) The Tonnis critenrion of acetabular index upper limit 35 degrees. (2) The position of femoral metaphyseal "beak" with Perkins and Hilgenreiner's lines, showed: 21 CDH/204 risk newborn or 10.24% with 7.35% Dislocatable Hip, 2.93% Complete Dislocation; Female = 9.5:1; Left side: Right side=3:2.

The results of the basic immunization of 3 doses of oral poliomyelitis vaccines for infant and boost immunization of 2 doses of oral poliomyelitis vaccine during 1993-1997 have shown that the poliomyelitis was significant reduced from 152 cases in 1993 to no case in 1998. The last case of poliomyelitis occurred in Phu yen province in 19th January 1997. In 2000, the poliomyelitis was eradicated in Vietnam. However, in order to prevent from returning the disease

Data were collected from the Enlarged Immunization Program and the Poliomyelitis Eradication Program (1992-1999), also including inquiry forms and guidelines for detecting, investigating, and processing by Epi-Info. Results shown the epidemic was spread in prevailing of rural population (79.3%), under 5 years old children accounted for 87.9% of cases of poliomyelitis. The outbreaks occurred all around the year with the peak on March, April, May and September, October. Wild virus of the type 1 plays the main role in 97.8% of cases
Poliomyelitis ; Epidemiology

All children in suspicion of poliomyelitis from 28 provinces of North Vietnam (from 1993 to 1999) were enrolled in study performed with a form of inquiry concerning all related personal health documents and reports. Results shown that all children suffered from poliomyelitis with isolated wild poliovirus accounted for 73.4% were primarily non-immunized or under-dose-immunized. Conclusion recommended the continuation of oral immunization among all under-one year old children in combining with the providing two doses of oral vaccine per year for under five years old children

3 types the results were evaluated according to the efficacy of obtained vaccines have shown that the mininal infective dosages of poliovirus in production of oral live poliovirus vaccine in the renal cells of monkey which given the highest efficacy were 103 TCID 50 /bottle of Roux, 104TCID/bottle of Roux and 103 TCID/ bottle of Roux for type I (strain: WHO-IS-C), type II (strain: IIS-90A) and type III (IIIs-79A), respectively
