Background And Aim: Hospital-acquired infection (HAI) is a major problem worldwide. Understanding patterns of bacterial etiology and antibiotic susceptibility is vital to combating HAI. Besides, typing of isolates is important to establish the intra-hospital surveillance of resistant clones. In this study, we aimed to evaluate antibiotic resistance and genotyping of a number of gram-negative bacteria (GNB) causing HAI in patients who were referred to Children's Medical Center.
Methods: During the 6-month period, antimicrobial susceptibility profiles of GNB isolates recovered from patients in Children's Medical Center were determined. Typing of common GNB was performed by random amplified polymorphic DNA (RAPD) analysis and the results were analyzed by Gelcompar II software.
Results: In total, 142 (1.1%) gram-negative bacterial strains were isolated, among which 59.2% were from males. The most organisms were isolated from blood (63%) followed by wounds (13.7%). The greatest proportion of strains came from intensive care units (51%). Low sensitivity of to common antibiotics and high resistance of spp. To cefotaxime (100%) were reported. The most efficient antibiotics for strains were amikacin (84%) and gentamycin (81%). However, just 12.5% of strains were resistant to trimethoprim-sulfamethoxazole. The analysis of RAPD-typing revealed the presence of one clone in and and two clones in , whereas the trend varied completely in strains and spp.
Conclusion: The results of this study showed a possibility of an outbreak in the Children's Medical Center. Since there is a possibility of transmission of an infection from one patient to another, high attention should be paid to the basic methods of preventing infection.

Background: Stigma toward transgender children and adolescents negatively impacts their health and educational outcomes. Contact with members of stigmatized groups can dismantle stereotypes and reduce stigma by facilitating exposure to the unique cognitive and emotional perspectives of individuals within the group. Recent evidence suggests that video-based contact interventions can be as effective as face-to-face encounters, but challenges lie in protecting the identities of transgender youth, since many of them live in stealth.

Background: Food protein-induced allergic proctocolitis is a nonimmunoglobulin E-mediated, self-limited food allergy of the rectum and the colon. Cow's milk protein is the most common allergen responsible for the disease.
Objective: This study aimed to investigate the roles of different types of formulas in building early tolerance to food protein-induced allergic proctocolitis in infants.

Background: There is limited evidence on the association between maternal anemia during pregnancy and the risk of childhood allergic disorders, with regards to atopic eczema. The current pre-birth cohort study aimed to examine the association between maternal anemia during pregnancy and the risk of atopic eczema in Japanese 2-year-olds.
Methods: The study included 1354 Japanese mother-child pairs.
