Retrospectively, results of 64 leg open fractures (in 63 patients) treated by locally-made external fixators from April 1985 to April 1995 were examined. The distribution of these fractures according to Gustilo-Anderson classification was as follows: 15 fractures of degree II, 32 of IIIA, 11 of IIIB and 6 of IIIC. Mean age of patients age at the time of operation was 31 (range 18-63). Motobike traffic accident accounted for 85% of fractures. Skin graft, flaf surgery and operation were used. The follow-up mean time (of 64 legs) was 25 months (range 2-80 months). The mean duration of wearing external fixators was 22 weeks. 50 patients needed casting for average 6 weeks. In the Vietnamese setting, with approriate indications, well-performed debridement of wound, and closed postoperative follow-up, locally-made external fixators can be used and these may satisfactorily respond to the requirements of treatment for leg open fractures

Radical cystectomy for bladder cancer was preformed in total of 68 consecutive patients (53 males and 15 females) at Binh Dan hospital from August 2001 to August 2003. Histopathological examination revealed that the tumor grade was 1 in 19 patients (2 with positive node), grade 2 in 20 patients (10 positive node) and grade 3 in 28 patients (15 positive node). The pathological stage was pT1 in 2 patients (no positive node), pT2 in 50 patients (17 positive node), pT3 in 15 patients (12 positive node) and pT4 in 1 patient (positive node). Among 68 patients underwent radical cystectomy, 35 patients had cultaneous ureterostomy, 26 patients had a Carmey II plasty with ileal-conduct uriary diversion, 5 patients with urinary diversion of Kock plasty and 2 patients had a Bricker operation

In 2002, DHF viro-serological surveillance was started in 19 Southern provinces of Vietnam. 247 DEN virus strains (consist of 27 DEN-1, 99 DEN-2, 9 DEN-3 and 112 DEN-4) were isolated from 3318 blood samples. The predominant serotypes were DEN-4 (45.3%) and DEN-2 (40.1%). DEN-2 virus was more positively correlated with severe cases in comparison with other serotypes. However, high rates of virus isolation were obtained from DHF grade I-II patients (49%), and then from DF, viral infection and fever of unknown origin cases (40.1%). These should be main target subjects for the active surveillance of DHF. In addition, MAC-ELISA was done on 7498 DHF serum samples taken in Southern Vietnam with the average positive rate of 44.37%

This report described a program undertaken with the collaboration of the CDC (Colorado, USA) known as "Active, laboratory-based surveillance for dengue infection in Bien Hoa city in 2002". Results of this study are as follows: The predominant serotype which circulated in Bien Hoa city in 2002 was Dengue-4. The number of children Dengue ; epidemiology ; laboratories

Bladder cancer is a significant public health problem. Significant progress has been made in understanding the underlying molecular and genetic events in bladder cancer. However, there remains a great need for the development of reliable markers that can provide clinically useful information regarding diagnosis and prognosis and to facillitate the selection of appropriate therapy in individual patients. Ongoing and future investigation is anticipated to refine treatment of patients with bladder cancer

Study on clinical features and epidemiology among 10 patients had avian influenza A who treated in hospital in Ho Chi Minh City and Ha Noi 12/2003 and 1/2004, 13,7 mean age. In all patients, the diagnosis of influenza A (H5N1) was confirmed by means of viral culture or reverse transcriptase polymerase chain reaction (RT-PCR) with primers specific for H5 and N1. None of the 10 patients had pre-existing medical conditions. Nine patients had a clear history of direct contact with poultry. All patients had fever, respiratory symptoms and clinically significant lymphopenia. The medium platelet count was 75.500/mm3. Seven patients had diarrhea. In all patients, there were marked abnormalities on chest radiography. There was no definitive evidence of human to human transmission, eight patients died

Retrospectative study on 20 infants with dengue heamorrhagic fever was confirmed by Mac ELISA at Chau Doc Hospital in 2001, study group was 6 infants < 12 months age, control group was 14 infants > 12 months age. 100% high fever; 66,7% subcutaneous peteachie; 66,7% hepatomegaly; 50% gastro-intestinal bleeding; accompany with respiratory infection were the most common signs. 100% hemoconcentration; 80% glomerule under 100.000/mm3. The rate of dengue shock syndrome was rather high. IgG antibody which infants less than 1 year old transplacetally received from their mothers caused antibody dependent enhancement of infection, so they with primary-type infection were at risk of dengue shock syndrome as in older children with secondary infection

The first Viet Nam baby born from intracytoplasmic sperm injection using testicular sperm from impaired spermatogenesis testes in 1/3/2004. There was approximately 50000 sperm after preparation, among them 20% was motile. From 12 retrieved oocytes, 11 were mature and therefore injected. Five oocytes fertilized and developed into 4 embryos. Embryo transfer was carried out for all 4 embryos. One embryo implanted and kept growing till the 37th week of pregnancy. Patient underwent ceasarian section

At HungVương Hospital, 17-48 hours after birth, 58 newborn babies with fetal age of 39,5 weeks in average underwent a neurological examination. Results showed that in comparing with the original British cohort, Vietnamese newborns had got significantly lower scores in 10 out of 25 indicators, including almost relating to truncal tone. Among these studied subjects, the deficiency of long chains fatty acid was unsignificant, while this group of fatty acids was related strictly to the nerve, especially ophtalmic nerve. The relation between transketolase concentration with neurological status was not identified

110 cases of unruptured ectopic pregnancy were treated, among them 61 cases (55,5%) with 1 dose of methotrexate, 40 with 2 doses (36,4) and 9 with 3 doses (8,1%). Successful rate reached 90,9% (84-95%). β- HCG took 13 (±10,3) days to return to negative point. It took 31,8 (±20,7) days for ectopic pregnant mass to disappear. Not any severe side effect was notified, except 5 cases of nausea. After treating and 12 months of follow up,47,8% of cases had got new pregnancy, among them,9,9% had reccured ectopic pregnancy. Methotrexat is an efficacious internal therapeutic for unrupted ectopic pregnancy
