To evaluate the effects of zinc on chronic anorexic children, we have divided 132 chronic anorexic children aged 3-48 months old into two groups. The test group was supplemented with iron, vitamins and 10mg of elemental zinc daily orally while the control group was supplemented with iron, vitamins. The results have shown that appetite, energy intakes and growth rate in the test group were improved better than those in the control group (P<0.001; P<0.001; P<0.001 and P<0.025). Initial serum zinc concentration of the chronic anorexic children in the test group is concerned obviously with rehabilitations of energy intakes (P<0.002). Weight and height velocities of the anorexic children with low zinc concentration in test group were lower than those of the anorexic the test group (P<0.005; P<0.005). Zinc supplementation has clearly affected to treat chronic anorexia in children.

Background: Paralysis has been eliminated in Vietnam in 2000. To maintain the achievement, Vietnam needs to have more than 90% of children under 1 age drinking 3 doses of OPV, controlling cases of acute flaccid paralysis and diagnosing for virology in laboratory to determine causes of the disease. Results of laboratory identifying Polio virus and enterovirus in patients with acute flaccid paralysis is evidence of successful in paralytic elimination annually in Vietnam.\r\n', u'Objectives: To of isolate polio virus and enterovirus in patients with acute flaccid paralysis suspected paralysis in 2005.\r\n', u'Subjects and methods: The study included 267 cases with acute flaccid paralysis from 29 provinces, cities in the North and six provinces in the Central of Vietnam during 2005.\r\n', u'Results:Results of surveillance for acute flaccid paralysis and indicators of samples tested in 2005 have reached the criteria regulated by the World Health Organization. 8 poliovirus strains and 56 other non-polio enterovirus strains were isolated from 538 stool specimens of above patients. All isolated poliovirus strains were confirmed as Sabin-like strains. 56 non-polio enterovirus strains included coxsaxkie A (3), conxsackieB (5), echoviruses (34), enterovirus 71 (1) and untyped enteroviruses (13). Wild polio virus was not isolated in 2005.\r\n', u'Conclusion: The result confirmed successfulness in maintaining of poliomyelitis free status in the North and 6 provinces of the Central of Vietnam in 2005.\r\n', u'\r\n', u'\r\n', u'

From Nov 1997 to Nov 2000, at the Pediatrics Department of Hue Central Hospital, a study was performed on 132 children (87 males and 45 females) of an average age of 14.510.8 months. Results: in 64 subjects lung auscultation symptoms were (+). Lung auscultation symptoms incidence was 48.48% generally. The method had great value in diagnosis of pneumonia, with high specificity, however it is appropriate only at the medical institution at high levels

In order to study on epidemiological factors, clinical manifestation of AIDS patients in Vietnam, a retrospective study on 5247 AIDS patients in the whole country has been conducted from 1993-2001. The results of study showed that most of AIDS patients were male and young and almost cases used the injection. Clinical manifestations were prolonged fever and persistent diarrhea over 1 month and persistent diarrhea. Duration of HIV infected to AIDS and to death was short. It needs to implement voluntary counseling testing program and strengthen AIDS survey activities in Vietnam.

From 1991 to 1994, 203 poliovirus positive cases were identified among 559 patients with acute flaccid paralysis. Of these 207 isolates: 175 cases were caused by poliovirus type 1, 7 by type 2 and 11 type 3. Most of these isolates were intratypically differentiated by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Of the studied 142 isolates: 107 were wild type 1 poliovirus strains, 7 were wild type 3 poliovirus strains, the remaining strains were Sabin vaccine-like strains. 107 wild type 1 poliovirus strains were divided into 7 groups by PCR-RFLP patterns and were also classified into 3 genomic groups by nucleotide sequencing and phylogenetic analysis. There were 3 unique wild poliovirus strains were circulating in Northern Vietnam during period 1991-1993. In 1994, no wild poliovirus was isolated

This study aimed to determine the rate of HIV, BBC and HCV infection and some risk factors of infections among prisoner in 5 prisons in Thanh Hãa during 4/2000 - 7/2001. The results showed that the rates of HIV, HBV and HCV infection were 15.7%, 22.9% and 61.9%, respectively. The risk factors included tutoring, repeated use of syringe and needle, improper sterilization of syringes and duration of drug addiction more than 12 months. The intercourse before marriage, blood transfusion influenced unclearly on the HIV, HBV and HCV infection

Study 3 representative districts of Ho Chi Minh city on number of people and the risk of acquiring HIV. The result shows some factors relating to high risk of acquiring HIV: 75,8% HIV found in drug addicted persons, especially the number of prostitute using drug tends to increase, and risker is easy and depraved life including using the same injection needle and do not use comdon when clients order. Besides, other factors include street children with the age of 10 to 19, construction workers. Therefore, there is a need to improve the awareness and practice skills to change behaviors leading to high level of acquiring HIV. And enhance the capacity of staff and their profession and skills in managing, caring, consulting and treating HIV-infected persons

On 200 samples of CSF with negative reaction to cephalitis virus from children suffering from acute cephalitis at National Institute of Pediatry and 250 fecal samples of healthy children aged of 2-6 years in kindergartens and creches, an investigation was performed in the year 2001. 44% of CSF sample had positive reaction to enteroviruses, among them 96.6% were ECHO 30/virus, the rest samples were ECHO 6. The incidence was 1.7 time higher in boys than in girls, their 97% were 3-14 years old. The epidemy appeared in June-July. Clinical symptoms were headache 100%, fever and nausea 90%, stiff nape 72.7%. The rate of enterovirus in healthy children accounted for 70% in 2 year old age children and 6% in 5 years old children

Research on 31 patients (include 24 man and 7 woman) at 20 to 60 years old who treated active hepatitis B at The army centre hospital 105 from 1/1999 to 6/2002. Result: HBV-DNA level in plasma increase follow agreeable rate with SGPT content: SGPT increase to > 100U/L correlative HBV-DNA patients(+) ≥10copies, 16,13% HBV-DNA patients (-) from 5 to 10 copies. The development of the disease in active hepatitis B patients was showed at relationship of marks of HBV with HBV -DNA(+) 70,96%, Anti-HBV-IgG (+) 100%, anti-HBc0IIgG (+) and anti-HBc-IgM (+) 12,90%, HBV-DNA (+) and HBeAg (+) 41,94%, HBV-DNA(+) and anti-HBe (-) 38,72%. HBV-DNA may be importance mark in following up development of the disease
