Pseudomonas aeruginosa is resistant many antibiotics currently, including new generation, broad spectrum antibiotics that were very effective with other bacteria. Thus, it's difficult to treat P. aeruginosa infection with these antibiotics. Author collected P. aeruginosa strains from some hospitals in Hanoi, tested with more antibiotics in order to determine antibiotic resistant rate and types, to orient some mechanisms of antibiotic resistance of P. aeruginosa. Materials is 97 strains of P. aeruginosa isolated from blood and pus of patients treated at Bach Mai Hospital and National Institute of Burn from August 2002 to November 2003. Method: disk diffusion antibiotic sensitivity testing (Kirby - Bauer test). Results: Isolated P. aeruginosa strains are multiple antibiotic resistant (8 of 16 antibiotics), especially hospital infection strains are resistant 100% of tested antibiotics. It showed the potential roles of some enzymes such as penicillinase, cephalosporinase, AAC(6), ANT(2")-1, and ANT(2") enzymes that inhibit effects of antibiotics in bacterium cell

Tympanoplasty by underlay technique is one of different methods for treating of chronic Otitis Media. Temporal muscle fascia is chosen material for the tempanic graft with good result. The surgeons can choose many methods and grafts and the results do not depend on the methods but on the skill of surgeons. 119 cases of tympanoplasty is reported, of which 83% is good results.Taking out carefully of the reformed mucosa in the middle ear plays an important role in the results

In the period from Aug 2002 to Aug 2003, at the National Institute of Burn strains of S. aureus and 45 strains of P.aeruginosa were isolated from the blood of severious septicemia patients.In disk diffusion test,100% of S.aureus strains were resistant to penicillin, erythromycine, kanamycine, tobramycine, gentamycine, oxacilline, 36% in particular, resistant to vancomycine and 45% to teicoplanine. 100%,of P.aeruginosa were resistant to ticarcilline, cefoperazol, gentamycine, tobramycine and 50% were resistant to ciprofloxacine.The most common effective combinations were rifampicine+acide fusidic, or rifampicine+ vancomycine for S. aureus, and imipenem + fosfomycine or imipenem+netilmycine, or imipenem +piperacillin/tazobactam for P.aeruginosa

A study on 56 children with bronchial asthma in the Institute of Pediatrics during 5-10/2001 has shown that the bronchial asthma is increasingly, accounted for the high rate among respiratory tract diseases. The disease occurred in men more frequently than in women in which children with ages of 5-10 accounted for highest rate of disease. The severity of bronchial asthma did not much influence the children's life. The treatment should be considered for individuals and involved the combination of corticoids and 2-adrenergic stimulant.

Background: In a chemical war during 1961-1971, about 94,000 tons of the herbicides were sprayed over Southern Viet Nam.A main component of the herbicides is dioxin that is very harmful to humans. There are many studies focusing on people\u2019s health due to exposure to dioxin residuals. Objective: To investigate the health issues related to exposure to dioxin residuals. Subjects and method: A retrospective comprehensive survey performed on 4018 people in Cam Chinh commune, Cam Lo district, Quang Tri province and compared with 3987 people in Cam Phuc commune, Cam Xuyen district, Ha Tinh province (controls) based on epidemiological interviews. Results: The morbidity was higher at 6.4% in the herbicides-applied area than in the herbicides-non applied area. In herbicides-applied area, there was a high risk of diseases such as bone connective, genitourinary, blood endocrine system, skin and infectious diseases. Factors such as age, sex, familiar income, drinking, smoking and agricultural chemical usage contributed towards the health of the affected population.Conclusions: Agent orange/dioxin pollutions still have the potential to be hazardous to human health in the herbicides-applied areas.

Background: Dioxin affects nervous system via the system of nervous communicative hormones and endocrine hormones, causing disorders and nervous behavior wrongs. Reproductive health is one of the serious effects of exposing Agent Organe/Dioxin. Objectives: To evaluate the birth defects of the nervous system of children, from the generation of veterans exposed to Agent Orange/Dioxin during wartime and to assess congenital nervous defects related factors, characteristics in these subjects. Subject and methods: A retrospective cohort, interview and examine 12.369 exposed and 7.659 unexposed Hanoi veterans, their birth defective children were examined by the pediatrics. During the 2002-2003 timescale. Results: A statistically high significant rate of reproductive failures and birth defects for exposed veterans, compared to unexposed ones, spontaneous abortion with relative risk RR = 4.18, hydatidiform mole with RR = 3.0, still births with RR = 2.2, birth defects with RR = 2.12. Nervous birth defects were highest; representing more than 40% of live births; the relative risk of the exposed group is 2.3 fold higher than the unexposed group, with p < 0.01. The birth defects increased significantly: mild mental retardation with RR = 3.5, severe mental retardation with RR = 3.5, Down's syndrome with RR = 2.16. Conclusions: Nervous birth defects of children of the Hanoi veterans exposed to Agent Orange during wartime accounted for the highest rate. Congenital nervous defects in male were higher than female. Exposed time, exposed levels and direct exposure to Agent Orange were significant related factors in this study. The increase of birth defects was in correlation with exposed levels.

50 patients with the odontopathy and odontic advantages of technique of the three dimensional obturation/warm vertical condensation of gutta- percha included easy implementation, close obturation of the accessory root canals and high rate of healing the lesion of endodontic origin and limitations included no application for the odontic pedicle that have not been closed.

In the period from 1995 to 1997, this simple method was performed at the Institute of Mothers and Neonates Protection and Care in 107 female subjects to investigate the endocrinological function. The method is preferable in the early stage of menstrual cycle, especially for retrospective diagnosis to check the response to the treatment.

23 patients with mitral stenosid with or without mild mitral open, ages of 23-50 (male: 10) received an operation. As the results of direct measurement of pulmonary arterial pressure and left atrial pressure in an operation have shown that the pulmonary arterial pressure was direct correlated before and after operation(r= 0.572 before operation; r=0.65 after operation).These parameters were reduced significantly and rapidly after operation when comparing with these before operation.

A study on the morbidity rate of gonorrhea in Hanoi hospital of Dermatology and Venerology has shown that the rate of isolated gonococcus (neisseria gonorrheae) were 14.31%. This rate in male was higher than this in female. The morbidity rate of receptionist much higher than this than this of others.
