Eight kinds of Salmonella antigens have been made at the Pasteur Institute HoChiMinh City: OA, OB, OC, Otyphi and HA, HB, HC, Htyphi. Three more kinds of Salmonella antigens were developed: Salmonella Vi, ENH (S. enteritidis) and TMH (S. typhimurium) for differentiation of antibodies from typhoid (0:9,12 H:d) and S. enteritidis infection (0:9,12 H:g, m) and antibodies from paratyphoid B (0:4,5,12 H:b:-) with S. typhimurium (0:4,5,12 H:i:1,2). Salmonella Vi antigen is useful for the study of Vi antibody in epidemiological investigation on typhoid fever

34 paired mother - infant blood samples collected from neonatal tetanus cases in National Institute of Pediatrics, Hanoi were examined for tetanus antibody. The results showed that 100% of blood samples were negative in both mothers and their infants.

Fracture of the shaft of femur and tibia in children aged from 4 to 17 sometimes caused the problem in reduction and immobilization and needed an osteosynthesis. Among the internal fixation procedures, intramedullary nailing by using Metaizeau’s flexible wire under C-arm control showed the best way and the best choice. 30 fractures of the shaft of femur and tibia failed in conservative treatment have been operated by above methods with successful results since Jan-1996 to February-2000 in Saint-Paul hospital. The advantages of the method were noted as no opening fracture focus, no bleeding, no risk of infection, short stay in hospital and no need of cast immobilization. So patients will come back soon to theirs activities and school.

In Dak Lak province, there are 4 plague foci included EaHleo, Hoa Thuan, Krong Pack, and Cuzut. Among them, EaHleo is a new focus, and Hoa Thuan Krong Pack Cuzut were old foci (from 5 years to more than 10 years no epidemic). We conducted the study in these plague foci during the dry season between 1997-1998. The investigation of serum samples from 1,041 R.exulans is the above 4 foci show that anti-F1 antibody was found with an average rate of 26.6% in the 4 investigated foci. This rate was 34.4% at EaHleo with titer ranging from 1:20 to 1:2,560. The positive rates were 3.8%, 5.4% and 9.7% at Krong Pack, Hoa Thuan, and Cuzut, respectively, with titer ranging from 1:20 to 1:80.

Study the rapid serodiagnosis of typhoid fever in 41 samples collected at Saint Paul Hospital, Traffic-Transport Hospital, centers of preventive medicine in Hanoi, Lai Chau, Thai Binh from 2002 December to 2003 June. Results: IgM(+) and IgG(+) in 29 samples, IgM(-) and IgG(+) in 8 samples, IgM(-) and IgG(-) in 3 samples, and 1 unspecified sample. Most of typhoid patients eliminated bacteria in feces 4-12 weeks after recovery. Few patients continued elimination after 12 weeks. Typhi-Dot technique overcomes disadvantages of Widal reaction, gives quick result within 1 hour, has high sensitivity and specificity, simple technique, not requires expensive equipments, and could test many samples at the same time

The sensitivity and specificity of 3 diagnosis kits for typhoid fever – Kit PanBio (American), Kit Typhi Dot (IgM, IgG) (Malaysia) and Kit Tubex (Sweden) were determined on 434patients with fever, examined at Cai Lay District Hospital – Tien Giang province from Oct 2001 to March 2002. The results were compared with Widal test. Results showed a same convenience in all three kits. The Kit Tubex particularly has a high cost but rapid results. The Kits Typhi Dot and Tubex gave high sensitivity and specificity with a reliance enough in rapid diagnosis of typhoid fever. Widal test is less sensitive and difficult to read the result, however it is the most common test in laboratory
