Antibody efficacy was investigated on 98 children after hepatitis B vaccination at time of 30 months after the first dose in HuÕ City. It was found that only 30.6% of children who were vaccinated in 1998 have antibody response at protectable level. 100% of those have low-level antibody response. Cause of poor antibody response can be the duration between the first and the third doses is short. 100% of children were injected vaccine at the delta muscle, instead of the lateral-anterior thigh.

The descriptive cross-sectional study on 424 forms at Oncologic hospital to find the causes of overload in Janruary 2003. The results showed that: the mean age 38  14 years old; male 17.7%, female 82.3%. There was no difference between Ho Chi Minh city and provinces. The patients at out-clinic examination ward increased 3 times. Having 54% patients were treated at home by following doctors' prescriptions. The most common reason is confidence in Oncologic hospital because of best specialists 86.8%. In other hand, almost reason for not examined at their local medical station because of losing their confidence 68.2%.

An inquiry conducted with 410 pediatric patients showed that in March 2002, the overloading increased 4 times in comparing with the designed indicator. The causes are that: 71.8% did not visited the local health station because of the loss of believe due to the lack of pediatric specialty, 60% because of prolingation of treatment without helpfulness, 13.2% because of the lack of equipment, 10% because of the bad quality of physicians, 0.7% because of the poor administration and management. Therefore it must promote and strengthen the quality of local health services, consolidate the network of pediatrics diagnosis and treatment at provincial level, and that of HCM City to favorize the function of higher level of specialization and of pediatric profession

An inquiry which was conducted with 473 patients of the Department of Surgical Diagnosis showed that in Binh Dan Hospital the number of patients was 3 times higher than designed indicator. Patients were attracted there because of their believe on the hospital due to high quality of medial staff good equipments, prosperity of medicaments and broad advertisement. In addition, because that people did not frequent the hospital at local level hospital due to the lack of believe, the lack of qualified specialties, the low skill of medical staff, the helpfulness prolongation of the treatment, the lack of good equipment and management

A cross-sectional study was performed with 410 inquired cards in Department of Surgical diagnosis in Hospital of Pediatrics No1, Ho Chi Minh city from 18-26 March/2002 to determine the causes of overload of patients. The number of children, who frequented to the clinic were 5 times higher over the capacity. 93.7% of pediatric patients accompied their parents, 95.3% received the medicines for treating at home, 82.25% of patients believed the Hospital due to completed sepecialties of pediatrics, 86.8% due to good equipments, and 17.6% due to the plenty of medicines. 71.8% of patients did not rely on local health facilities due to the lack of pediatric specialities and the prolong recovery from disease 60%, due to the low qualified physicians 10%, due to the lack of proper equipments 13.2%

Background: Adolescent is a special period in life with the transition from childhood to adulthood. At this age period, adolescent experience physical and psychological changes with typical characteristics of puberty is the first ejaculation in male and first menstrual cycle in female. Objective: To explore the onset of puberty and knowledge on pubertal changes, sexuality and contraception in adolescent and various related factors. Subject and methods: A longitudinal study of adolescent health is conducted on 12.447 subjects (including 6.108 males, 6.339 females), living in Chi Linh district, Hai Duong province. Data used in this article is from the baseline survey of the adolescent health research project \u2013 a field site of the Hanoi School of Public Health. Results and Conclusion: The pubertal age is 15.6 years for male and 14.6 years for female. The onset of puberty in girls is earlier than that in their boy counterpart and is earlier in younger age groups, that suggest the trend of earlier onset of puberty in adolescent. The pubertal age is earlier in urban adolescent compared to the rural ones and is earlier among those having better economical conditions compared to poorer ones. The difference is statistically significant (p<0.05). Adolescent lack of knowledge on puberty, sexuality and contraception. 57.8% of adolescent knows at least one of the pubertal characteristics and only 6.5% of males and 17.6% of females knows the time most fertile in the female menstrual cycle. 49.6% of adolescents have heard about contraception, in which 56% of them (53% males and 58% females) heard about condoms. In general, the knowledge on puberty, sexuality and contraception is higher in female, urban adolescent, higher education and older adolescent. The difference is statistically significant (p<0.05 or <0.001).

Objective: In Viet Nam, tuberculosis (TB) prevalence surveys revealed that approximately 98% of individuals with pulmonary TB have TB-presumptive abnormalities on chest radiographs, while 32% have no TB symptoms. This prompted the adoption of the “Double X” strategy, which combines chest radiographs and computer-aided detection with GeneXpert testing to screen for and diagnose TB among vulnerable populations. The aim of this study was to describe demographic, clinical and radiographic characteristics of symptomatic and asymptomatic Double X participants and to assess multilabel radiographic abnormalities on chest radiographs, interpreted by computer-aided detection software, as a possible tool for detecting TB-presumptive abnormalities, particularly for subclinical TB. Methods: Double X participants with TB-presumptive chest radiographs and/or TB symptoms and known risks were referred for confirmatory GeneXpert testing. The demographic and clinical characteristics of all Double X participants and the subset with confirmed TB were summarized. Univariate and multivariable logistic regression modelling was used to evaluate associations between participant characteristics and subclinical TB and between computer-aided detection multilabel radiographic abnormalities and TB. Results: From 2020 to 2022, 96 631 participants received chest radiographs, with 67 881 (70.2%) reporting no TB symptoms. Among 1144 individuals with Xpert-confirmed TB, 51.0% were subclinical. Subclinical TB prevalence was higher in older age groups, non-smokers, those previously treated for TB and the northern region. Among 11 computer-aided detection multilabel radiographic abnormalities, fibrosis was associated with higher odds of subclinical TB. Discussion: In Viet Nam, Double X community case finding detected pulmonary TB, including subclinical TB. Computer-aided detection software may have the potential to identify subclinical TB on chest radiographs by classifying multilabel radiographic abnormalities, but further research is needed.
