87 children aged 7-15 years old were treated in Dong Thap General Hospital from October 1999 to April 2000 were diagnosed as typhoid fever. Patients underwent routine examinations, blood culture and bone marrow culture, and clinical care. Results showed that: Mab-based dot-blot ELISA technique for diagnosing typhoid fever on pediatric patient urine sample was a rapid technique, easy to collect sample, stable sensitivity and specificity, it could be combined with blood culture for early diagnosis of typhoid fever, especially in patients, which underwent treatment. The assay was easy to realized without complicated equipment, and easy to observe the result.

The typhoid is common disease currently. 316 patients with typhoid diagnosed in Thanh Hoa hospital during 1994-6/1996. The wrong diagnosis of typhoid is frequent. The wide use of the anti-pyretic agents missed some symptoms, even complications. Most of physicians diagnose wrongly with the malaria that not basing on the epidemiology. Therefore, almost of patients wit typhoid in Thanh Hoa provincial hospital were treated by antimalarial drugs. It is difficult to prevent from the disease because it can be not control the salmonella typhi carrying patients after free disease

A descriptive prospective study of hospitalized Dengue including Dengue Fever (OF) and Dengue Haemorrhagic Fever (DHF) was undertaken in An Giang General Hospital. An Giang Province from April 2002 to May 2003. A first blood sample (BS) will be taken on admission to detect dengue antibody by Elisa (IgM and IgG) and virus isolation. The second BS will be drawn on discharge with the same test. If the patient is discharged before day 10th after the onset of fever, a third BS will be planned, for IgM and IgG too. In the hospital, all patients will be follow-up adequate platelet count and haematocrit. - There is 1009 patient selected (less than 15 years old), 5 DHF deaths due to DHF and 4 deaths due to others. Classification of the Dengue hospitalized cases: DF (28. 5%), DHF (49%) and DSS (10%). - The highest positive IgM rate is belong to DSS patient group (89%) and then DHF, the lowest rate is DF (34%). The virus isolated rate of the DSS patient group is highest (16.8%), and then DF (14.6%). DEN2 is predominant (with 84% of all virus isolated), and then DEN4 (8.8%). - On the admission, there are the overload for Dengue diagnosis. 12% cases with DF/DHF on the admission but they are typhoid fever, measles and viral infection on the discharge. - Clinical and laboratory findings are the more severe (thrombocytopenia and haemoconcentration), the more positive IgM rate and virus isolated. - For the correspondences between DF, DHF diagnosis. Clinical and laboratory findings according to WHO criteria: there are only 22.2% of DHF satisfied 4/4 WHO criteria, 39.2% satisfied 3/4 criteria and ultrasound is the test supported for these DF, DHF cases. - 71% confirmed DHF cases and 26% confirmed DSS cases have not thrombocytopenia and haemoconcentration. - The haemorrhagic manifestation just appear in 46.6% of DHF cases, even if DSS cases, there are only 56.2% cases have got the haemorrhagic manifestations.

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 investigation of natural and social factors health service system, the composition of fever diseases, the characteristics of malaria showed that 80% of population had an awareness on malaria but there is shortening in the state system of antimalaria. Malaria occupies about 90% of total morbidity. Clinically, malaria has 18 kinds of sysptoms, 100% responsive to the MOH procedure of 5 days of artemisinine. The active measures to enhance the efficacy of diagnosis and treatment in the community such as comprehensive surveillance of the malaria control, training of the health staff had reached high efficiency to reduce in incidence to eradicate pernicious malaria within 2 years and to annual the mortality

Relapsing polychondritis is a rare autoimmune disease of unknown etiology with episodic but potentially progressive inflammatory manifestations. Auricular, articular and nasal manifestations are the most frequent disturbances. Fever is one of the manifestations of this disease but it rarely appears as an initial presentation. In this situation, the diagnosis is delayed until other manifestations are obvious. We report a case of relapsing polychondritis, which was presented as fever of unknown origin. Ten months after the onset of fever, auricular chondritis appeared and gave us the key to diagnosis.

Linear discriminant analysis method basing on genetic algorithms was used to find out the role of clinical symptoms for taking differential diagnosis between typhoid fever and scrub typhus. Clinical records of 526 patients suffering from one of those diseases were used as input data for algorithms. The results showed that the differential value of symptoms are as follows: roseola (4 points), infectious constitution (2 points), drum belly (2 points), ingestive disorder (1 points), decrease of white-blood cell count (1 point), congestion (-2 points), enlarge of lymph node (- 2 points), erythematous eruption (-3 points), eschar (-5 points). The diagnostic rule are a follows: total point >=3: typhoid fever, between 0 and 2 points: suggestion of typhoid fever, total point <=-3: scrub typhus, between o and -2 points: suggestion of scrub typhus. To re-test on 50 patients of those 526 patients randomly, the accuracy rate of this rule is at least 98%.

41 children aged 7-15 years with typhoid fever (S.typhi positive blood culture) treated at Dong Thap provincial hospital from October 1999 to April 2000, were evaluated concerning the severity of the condition and the outcome of cytokine response. Results showed that the use of cytokine antibody on dissolved receptors of cytokine could have high value in severe typhoid patients. The systemic elevation of cytokine, especially IL-6 was common in children with typhoid fever and associated with the severity and the progression of the disease, high level of cytokine in hospital admission point was an important prognostic sign.

The study of 113 heart failure patients with rheumatic fever at Hai Phong Children Hospital from 1995 to 2001. Carditis encountered in rheumatic fever for the first time was 58%, however carditis in rheumatic fever since the second time was 100%. The valvular sequelea was only encountered in severe cases and the more the disease the more the valvular sequelea had, the common sequelea was mitral insuffisance (45.18%). 93.92% patients were out of heart failure. While the mortality rate was 3.54%. 100% patients were treated using anti inflammation and anti infection, so the parallel treatment: anti inflammation and anti infection were especially necessary
