Background:The urocytogramme is a certain laboratory tests, although older. By studying the cellular elements from the wall of the bladder trigone desquamated in the urine, it allows cyto-hormonal diagnosis. It allows to assess the presence and importance of the biological effect of sex steroids. This examination is not commonly used because they are poorly known in our country. It's a review of how simple, noninvasive, inexpensive. Objectives:This study aims to learn about the value of urocytogramme in normal menstruation period of girls. Subjects and method:A study was conducted on 143 high school girls of Hai Ba Trung Secondary School, Hue city. The mean age was 15\xb18 months, completely puberty; the average weight was 45.7\xb16.8 kg; average height was 156.8 \xb18.5 cm. The duration of study was from September 2006 to May 2007. Results:Urocytogramme had the index which changed according to the phase of the menstrual cycle and correlated closely with sex hormone concentrations in the ovulatory phase. The IK index had the value in ovulation diagnostic phase with the sensitivity and specificity concentrations equivalent to LH and plasma Estradiol. Conclusion:Urocytogram was a useful test for the diagnosis of in normal menstruation period of adolescent girls. It was easy, cheap and truly reflected oestrogen activity to help doctors making decision for the treatment of lasting amenorrhea disorders.

Background: Heparansulfate Interacting Protein (HIP) is up-regulated in various human cancer cell lines at both transcript and protein levels. HIP expression is related to the differentiation status and cancer development. Objectives: To determine HIP in benign prostatic hyperplasia, prostatic intraepithelial neoplasia and prostate cancer tissues. Materials and method: Western blot method was used to determine HIP expression in 3 different types of prostate tissue, including 11 prostate cancer samples, 2 benign prostatic hyperplasia samples and 11 prostatic intraepithelial neoplasia samples. Results. HIP was particularly up-regulated in prostate cancer and prostatic intraepithelial neoplasia, indicating that up-regulation of HIP expression may be an early event in tumorgenesis. Conclusion: The expression of HIP was different between cancer, prostatic intraepithelial neoplasia tissue and benign prostatic hyperplasia. HIP may serve as a prognostic marker for prostate carcinoma.

Background: People with disabilities have been coping with barriers that make it difficult for them to access public services. Many of them are poor, illiterate and out of work. Objective: To describe some characteristics of disabled people living in the communities of Chi Linh district, Hai Duong province. Subject and methods: Interview all of the 18.473 disabled people living in the seven communities of Chi Linh district, Hai Duong province. The contents of the interviews includes: economic-social information (income, education, job and martial status) and disability status (disability form and cause). Results: Nearly three fourths of disabled people are at the age of 45 and over. There are more women than men, with the male/female ratio at 1:1.8. Almost all of the disabled people are the Kinh in Chi Linh and 10.8% of them belong to the poor households. One in ten disabled people are illiterate and two thirds of disabled adolescents are at lower secondary school or lower. Difficulty in seeing is the most common among the kinds of disabilities, accounting for 81.9% of disabled people and about three fourths with one disability. Among the causes of disability, aging accounts for 71.5%, this is followed by illness. Conclusion: There is the need to reduce the rate of disability at the age of 45 and over, reducing the rate of sight related difficulties and increasing the accessibility of disabled people to educational services.

Nutrition Research and Practice 2022;16(5):658-672
BACKGROUND/OBJECTIVES:
Although children of ethnic minority groups are experiencing a transition from a predominance of undernutrition to overnutrition, there is little evidence of a dual-malnutrition burden. Therefore, this study examined the double burden of malnutrition among school-aged ethnic minority children living in mountainous areas and its association with their diets.
SUBJECTS/METHODS:
A cross-sectional study was conducted from September 2019 to March 2020 in 3 mountainous areas of Northern Vietnam among 1,556 ethnic minority schoolaged children. The prevalence of under-nutrition (stunting and thinness) and over-nutrition (overweight and obesity) were measured using the WHO 2006 child growth standards (height-for-age and BMI-for-age Z-score). Nutritional practices were evaluated by the frequency of food consumption based on a 4-level scale.
RESULTS:
The percentage of children with stunting and thinness were 14.0% and 5.4%, respectively, while the figure for overweight/obesity was 9.4%. The factors positively associated with stunting were living in a family with more than 2 children or being Muong/ other ethnicities compared to the Tay ethnicity. Children who consumed fish/shrimps/crabs or milk weekly/daily were less likely to be undernourished compared to those who never consumed these foods. By contrast, children who never consumed foods rich in vitamin A precursors and vitamin A and fruit or consumed daily snacks/junk food were more likely to be overweight/obese.
CONCLUSIONS
Undernutrition remains a common issue among school-aged children and adolescents of ethnic minority groups, while over-nutrition exists simultaneously. Public health nutrition programs promoting adequate diets and positive lifestyle changes related to nutrition are essential to tackle the double burden of malnutrition among ethnic minority children.

Purpose:
This study aimed to determine the occurrence rate of gestational trophoblastic neoplasia (GTN) and its related factors in aged women with hydatidiform mole (HM) in Tu Du Hospital, Vietnam.
Materials and Methods:
This retrospective cohort study included 372 women aged ≥40 years with HM diagnosed through postabortion histopathological assessment in Tu Du Hospital from January 2016 to March 2019. Survival analysis was used for GTN cumulative rate estimation, log-rank test for group comparison, and Cox regression model for determining GTN-related factors.
Results:
After a 2-year follow-up, 123 patients were found to have GTN at a rate of 33.06% [95% confidence interval (CI): 28.30– 38.10]. GTN occurrence meant that the time was 4.15±2.93 weeks with peaks at week 2 and 3 after curettage abortion. The GTN rate was remarkably higher in the ≥46-year age group than in the 40-to-45-year age group [hazard ratio (HR)=1.63; 95%CI: 1.09– 2.44], as was the vaginal bleeding group compared to the non-bleeding group (HR=1.85; 95%CI: 1.16–2.96). Preventive hysterectomy and preventive chemotherapy plus hysterectomy in the intervention group reduced the GTN risk compared to the no intervention group at HRs of 0.16 (95%CI: 0.09–0.30) and 0.09 (95%CI: 0.04–0.21), respectively. Chemoprophylaxis failed to decrease the GTN risk when comparing the two groups.
Conclusion
Post-molar pregnancy GTN rate in aged patients was 33.06%, much higher than that of the general population. Preventive hysterectomy or chemoprophylaxis plus hysterectomy are effective treatment methods to support GTN risk reduction.

The 5th outbreak of trichinosis occurred in a mountainous area of North Vietnam in 2012, involving 24 patients among 27 people who consumed raw pork together. Six of these patients visited several hospitals in Hanoi for treatment. Similar clinical symptoms appeared in these patients within 5-8 days after eating infected raw pork, which consisted of fever, muscle pain, difficult moving, edema, difficult swallowing, and difficult breathing. ELISA revealed all (6/6) positive reactions against Trichinella spiralis antigen and all cases showed positive biopsy results for Trichinella sp. larvae in the muscle. The larvae detected in the patients were identified as T. spiralis (Vietnamese strain) by the molecular analysis of the mitochondrial cytochrome c oxidase subunit III (cox3) gene.
