    Varicella is a vaccine-preventable disease, and the incidence of varicella has declined since the introduction of varicella vaccine campaigns. A wild type of varicella zoster virus (VZV) was isolated from a 33-month-old child with varicella in Korea in 1989, a different strain (MAV/06). A live-attenuated varicella vaccine containing strain (MAV/06), Suduvax (R), was developed in South Korea in 1994. Turkey introduced the varicella vaccine containing the MAV/06 strain (Varicella Vaccine-GCC, Green Cross, South Korea) in January 2019. Therefore, we aimed to compare the seroconversion rates among MAV/06 vaccine- and vOka-administered children. We prospectively collected blood samples from 98 received vOKA and 98 received MAV/06 children 6 weeks after administration, and seroconversion rates were determined by an indirect fluorescence assay (Anti-VZV IIFT IgG, Euroimmun, Germany). Seroconversion rate was significantly higher in vOka group than MAV/06 group (82.7% vs. 64.3%; p = .004). Of the children vaccinated with vOka strain, 17 children did not develop antibodies, 12 were weakly positive, and the remaining 69 children were strongly positive. Of the children who were administered MAV/06 strain, 35 were negative, 20 were weakly positive, and 43 were strongly positive. In conclusion, this study demonstrated that MAV/06 varicella vaccine had lower seroconversion rates and the strong seropositive cases were less common than vOka-administered children. Larger and prospective studies are needed.

    The Effects of Low FODMAP Diet on the Quality of Life and Gastrointestinal Symptoms in Children with Irritable Bowel Syndrome. A Pilot Study
    (Galenos Publ House, 2021) Ipek, Ecem; Ecevit, Cigdem Omur; Akisin, Zeynep; Teneler, Asli Ata; Bag, Ozlem
    Objective: Irritable bowel syndrome is a disease that negatively affects life. Recently, diet therapies have been emphasized. Our study, the aim was to investigate the effect of low FODMAP (fermented oligo-, di-, monosaccharide and polyols) diet on the frequency of gastrointestinal symptoms and the effects on quality of life in patients with IBS. Method: 18 children aged between 7-18 years, who were diagnosed with IBS, followed by University of Health Sciences Izmir Dr. Behcet Uz Children's Diseases and Surgery Training and Research Hospital the Child Gastroenterology, Hepatology and Nutrition Clinic were included in the study. The appropriate KINDL scale was applied at the time of application and 2 weeks after the end of the low FODMAP diet. GIS symptoms of the week 0 and 6 KINDL results were compared. KINDL scale was applied to the families before and after dieting and the results were compared. Results: The study was completed with 10 patients. The most common symptom was abdominal pain and it was present in all patients. All symptoms were found to decrease after diet but it was not significant. There was a significant increases in emotional well-being, family divisions and total KINDL results at the 6th week of diet in the children In parent KINDL scales, the results were not considered significant. Conclusion: Despite there was a decrease in GIS related complaints and increase in quality of life in IBS patients who underwent low FODMAP diet, it has been found appropriate to continue the study with larger patient groups for longer follow-up periods.

    Use of Different Iron Preparations for Prophylaxis and Effects on Iron Status in Infancy
    (Mdpi, 2024) Tosyali, Merve; Demircelik, Yavuz; Bag, Ozlem; Karaarslan, Utku; Gokce, Sule; Koc, Feyza
    Aim: To evaluate using different iron preparations for iron deficiency and/or iron deficiency anemia prophylaxis in infants and their iron status. Methods: In this study, we retrospectively evaluated the electronic patient records of 651 healthy children aged 9 to 13 months who met the inclusion criteria and who were followed up in pediatric follow-up outpatient clinics between January 2023 and June 2023. Results: A total of 651 children with a mean age of 11.2 +/- 1.4 months, 54.7% of whom were boys, who met the inclusion criteria were included in the study; 56.5% of the children were using Fe + 3 salt and the others were using Fe + 2 salt, microencapsulated iron, or sucrosomial iron drops. After the fifth month of prophylaxis, when the effects of the iron preparations used on the mean laboratory values were evaluated, it was found that hemoglobin, serum iron, and ferritin levels were lower in sucrosomial iron and microencapsulated iron users compared to other preparations (p = 0.001). When statistically pairwise comparisons were made between the groups, hemoglobin and serum iron values were found to be lower in the group using sucrosomial iron compared to the groups using Fe + 2 and Fe + 3 salts (p < 0.0001). Hemoglobin and ferritin levels were higher in the group using Fe + 2 salt compared to both sucrosomial iron and microencapsulated iron groups (p < 0.0001). When the infants were evaluated according to iron status, it was found that 208 (31.9%) had iron deficiency. Iron deficiency was found to be less in infants of families who defined their economic status as rich and in infants who used iron regularly (p-values 0.044 and 0.001, respectively). Iron deficiency/iron deficiency anemia was observed at a higher rate in the group using sucrosomial iron and microencapsulated iron prophylaxis (p = 0.001). Conclusions: To prevent iron deficiency, it is very important to use appropriate iron preparations for prophylaxis and to feed foods with high iron content. Although we found that families were willing to use different iron preparations other than iron salts for their infants, the results presented herein indicate that the rate of iron deficiency was lower in patients using iron salts. However, randomized controlled studies are needed to determine whether these preparations are effective in iron prophylaxis in infants.
