96 under 6-year-old children in Tu Liem and Gia Lam districts Hanoi were diagnosed as tracheal V.A. V.A children with pathogene bacteria make up a high rate, especially in the age 4-6. The common pathogene microorganisms in V.A children are H.influenzae, S. pneumoniae, S.pyogenes and S.aureus, among them the most common are H. influenza and S. pneumonia. A high rate of bacterial strains was sensitive experimentally to antibiotics, especially to norfloxacin. Antibiotic resistance to ampicillin, bactrim, chloramphenicol and erthromycine was reported. Most VA children are living in the house holds using charcoal, petroleum for cooking, and living with smoker parents

Investigation 54 E.coli strains isolated from nosocomial infection. The results as follows: - Only 46 of 54 E.coli strains were frequent positive with the afa pair of prime (85.2%). None of them have both afa and virulent genes for diarrhea. - Antibiotic resistance of E.coli (it was frequent afa positive) with ampicillin (80.4%), co-trimoxazol (58.7%) and cephalothin (56.5%). Antibiotic susceptibility of E.coli (it was frequent afa positive) with amikacin (97.8%), chloramphenicol (87.0%), gentamicin (71.7%) and norfloxacin (67.4%).

Investigating the biopsed gastroduodenal specimens collected from patients with gastroduodenal ulcer showed that: the gastroduodenal conditions can occur in all age groups, but they are most likely to be seen in the middle and old people. Gram stain and urease test from biopsed specimens gives result rapidly, especially with Gram stain. Rate of positive result is high (90.6% and 89.5%, respectively). Therefore, it can be based on the result of two these techniques to make diagnosis earlier

A study on the clinical symptoms and blood culture in 81 patients with typhoid septicemia has shown that the most typical symptoms in the typhoid septicemia comprised continuous high fever, anorexia, bloating and headache. Other symptoms comprised erythematosus, nose bleeding, hepatomegaly, spleenmegaly and diarrhea. The blood culture aimed at identifying the causative bacterial had a high positive rate within 96 hours after fever. This rate was very low in cases of antibiotic administration at home
Typhoid Fever ; blood

The culture of pus, fluid in the incisions, injuries from 540 patients in Saint Paul hospital has shown that 12.9% of samples infected with S.aureus. The isolated S.aureus rates resist to chloramphenicole, erythromycin, norfloxacin, cotrimoxazole, gentamycin, oxacillin were 50.3%, 38.4%, 20.5%, 24%, 20.1%, 17.6%, respectively. There was no occurrence of resistance to Vancomycin. S.aureus had a high sensitivity to common antibiotics such as Amikacin, cephalotin, gentamicin and norfloxacin.

A study on 6 operation theatre in Saint Paul Hospital during 1999-2000 has shown that there were 4 rounds of checking that did not meet the allowed standards of aerobic microorganism among 36 round of checking. In these 4 rounds, there were presence of S.aprophyticus and fungus. There was presence of P.aeruginosa and S.aureus and Enterobacteria in the air of operation theatre.
Bacterial Infections ; surgery ; hospitals

The bacteria most likely to cause hospital acquired infection are enteric those (35%), followed by S. aureus (25%), P. aeruginosa (13%) and S. pneumoniae (12.3%). S. aureus isolations have high rate of penicillin resistance, followed by chloramphenicol, ampicilline, cephalothine and oxacilline. P. aeruginosa has resisted to gentamycin and netilmycin and remains to be sensitive to amikacine, norfloxacine and ciprofloxacine. E. pneumoniae remains to be sensitive to most of test antibiotics, but it has resisted to chloramphenicol and penicillin. E. coli has high rate of resistance to ampicilline, cephalothine and chloramphenicol, but it remains to be sensitive highly to amikacin, netilmycin, gentamycin and tobramycin.
Bacterial Infections ; Sensitivity and Specificity

An analysis was conducted at some big Hospital in Ha Noi on 60 species of E.coli isolated from intestinal fluid and urine of the patients infected in bile duct and urological tract. Results showed that E.coli strains with or without afa gene causing infection of bile duct were rather resistant highly to ampicillin, and chloramphenicol, but sensitive to amikacin, cefataemi, norfloxacin. These E.coli infecting to urological tract and was resistant highly to ampicillin and chloramphenicol. Particulary, E.coli without afagene was resistant co-trimoxazole with higher percentage (72,7-58,3%).

From Nov. 1999 to April 2000, at Ha Noi Centre of Vereno-Dermatology, 365 samples isolated from patients of all ranges of age were studied, using the procedures of antibiogramme to determine the sensitivity of antibiotics to blennorrhagic agent. Results: 65 positive cases (17.8%), among them patients aged 16-40 account for highest positive rate (27.3%). Gonococcus has relatively high resistance to Penicillin (75.4%), then tetracyclin (21.5%), ciprofloxacin (6.2%). The resistance to Kanamycin (18.5%), Nalidizic acide (10.8%), Chloramphenicol (7.7%), Erythromycine (1.5%) were recorded. Multiresistance to 2 antibiotics had the highest rate: PG-TE (16.9%), PG-KA (15.4%), to 3 antibiotics PG-KA-NA (4.6%) was noted. There is no resistance to Ceftriaxon, Spectinomycin, Cephalexin

At the Department of Communicabe Disease of Ha Noi – Dong Da Hospital 546 patients (52 dengue fever (DF) patients and 44 dengue hemorrhagic fever (DHF) patients were studied. IgM antibody was quantified by ELISA, blood count by 680 plus device. Results: a leucopenia (<4000) 24.2% in DF and 15.9% in DHF. Thrombocytopenia 51.2% in DF. In DF, 81.8% exerted an antibody response; in DHF there were a high rate of stimulating lympho cells (84.1%), there is 100% correlation between stimulating lympho cell and IgM antibody response
