    Background: Adenoid hypertrophy (AH) is one of the possible causes of chronic inflammation in the middle ear. It has been suggested that CX3CL1 and its specific receptor (CX3CR1) could be related with the pathogenesis of some inflammatory diseases. The aim of the present study was to evaluate the role of CX3CL1 and CX3CR1 in the pathogenesis of AH with chronic otitis media with effusion (COME) in children. Materials and methods: Adenoid tissue samples were obtained from 91 pediatric patients and divided into two groups: adenoidectomy only for AH (n: 47) and adenoidectomy in conjunction with ventilation tube insertion for AH + COME (n: 44). Expression levels of CX3CL1 and CX3CR1 genes were compared. Results: Expression levels of CX3CL1 and CX3CR1 in hypertrophic adenoid tissue were not significantly different between the AH + COME and All only groups. Although no significant difference was detected in the expression of CX3CL1 in the adenoid samples, the expression of CX3CR1 was higher in children older than 48 months. Conclusions: When allergy, atopy and chronic adenoiditis does not exist to obstructive adenoid hypertrophy, inflammatory fractalkine chemokine expression levels in adenoid tissue was not observed to be increased in children with COME.

    The Genotoxic Effect of Nasal Steroids on Human Nasal Septal Mucosa and Cartilage Cells In Vitro
    (2023) Babakurban, Seda Turkoglu; Vural, Omer; Kasap, Yesim Korkmaz; Hizal, Evren; Yurtcu, Erkan; Buyuklu, Adnan Fuat; 0000-0001-5067-4044; 0000-0001-7157-0850; 35695134; AAI-8856-2021; AAJ-1454-2021
    Objective: To determine whether budesonide (Bud) and triamcinolone acetate (TA) cause DNA fractures in the nasal mucosa and septal cartilage cells through examinations using the comet assay technique. Study design: Prospective, controlled experimental study. Setting: University hospital. Methods: Septal mucosal epithelial and cartilage tissue samples were taken from 9 patients. Cell cultures were prepared from these samples. Then, budesonide and triamcinolone acetate active ingredients at 2 different doses of 0.2 and 10 mu M were separately applied to the cell cultures formed from both tissues of each patient, except the control cell culture, for 7 days in one group and 14 days in one group. After the applications, genotoxic damage was scored with the comet assay technique and the groups were compared. Results: In both the budesonide and triamcinolone acetate groups, the comet scores at low and high doses, on the 7th and 14th days were found to be significantly higher in both cartilage and epithelial tissue than in the control group. Conclusion: The study results showed that budesonide and triamcinolone acetate lead to a significantly high rate of genotoxic damage in both epithelial tissue and cartilage tissue.
