Gastrointestinal disease is one of the most common infectious diseases in the world. One of the most important causes is Helicobacter pylori infection. Considering the importance of this bacterium and its different prevalence in different parts of the country, this study was conducted to determine the prevalence of Helicobacter pylori infection and its related factors in 9-15 year old asymptomatic children in Birjand city.
This descriptive cross-sectional study was conducted on 332 children aged 9 to 15 years old in Birjand, in 1395. Individuals who had inclusion criteria were selected by multi-stage sampling. The demographic profile including age, sex, duration of breastfeeding, number of households, and number of yoghurt consumption per week, were completed for children. Helicobacter pylori stool antigen test was used in feces to evaluate Helicobacter pylori infection. Data were analyzed using Chi-square and Fisher's exact test at a significant level of 0.05.
Of the 332 children studied, 59 (17.8%) children had Helicobacter pylori infection. Our results showed no significant relationship between sex and duration of lactation with Helicobacter pylori infection (p> 0.05). However, with increasing age and number of family members, Helicobacter pylori infection was significantly increased (p Due to the prevalence of Helicobacter pylori infection and less frequently in dairy consumers should be given the necessary training for families.

Urinary tract infections are the second common infection in children، which cause renal parenchyma damage- as the most major sequel. This study aimed to investigate the prevalence of asymptomatic urinary tract infection (UTI) in primary school children of Hamadan City and drug resistance of isolated microorganisms in 2014. In this descriptive/analytical cross-sectional study، 350 urine samples were collected from the students of Hamadan City using the two-stage cluster sampling. The samples with positive nitrate and pH above 7 were cultured. Then، they were inoculated on the blood agar and Mac Conkey agar and after 48 hours of incubation، positive culture samples with at least 105 CFU/ ml were identified using standard microbiological methods. The sensitivity of isolated pathogens to 12 common antibiotics for gram negative bacteria and 11 common antibiotics for gram positive ones using the standard agar disk diffusion method was evaluated. The results were analyzed using SPSS version 19 and chi-square test. The results showed that from 62 (17. 7%) students suspected to UTI، 45 cases (12. 8%) were diagnosed. The most common isolated microorganisms were Escherichia coli 16 (35. 5%)، Staphylococcus aureus 14 (31. 1%)، Staphylococcus saprophyticus 9 (20%) and Enterococcus spp. 6 (13. 3%)، respectively. Also، it was found that E. coli was 100% sensitive to Nitrofurantoin. Regarding S. aureus and S. saprophyticus، amikacin was found to be the best antibiotic and ofloxacin for Enterococcus. Considering the prevalence of UTI without obvious symptoms in children، especially girls of primary school age and the probability of recurrence or its complications، screening، diagnosis and treatment of UTI in students is important. Furthermore، the impact of factors in the prevention of urinary tract infection with education in schools is essential.
