Objectives Eustachian tube dysfunction (ETD) is frequent in children with adenoid hypertrophy (AH). Although the most common treatment of AH is surgical removal of adenoid tissue, numerous studies have reported the efficacy of intranasal steroids. The effects of the intranasal steroid and azelastine combination on AH and ETD have not been reported before. In this study, we tried to determine the effects of 3-month intranasal Azelastine-Fluticasone dipropionate combination (Aze-Flu) treatment in children with ETD and AH. Materials and Methods 100 children who had open mouth sleep, snoring, and sleep apnea and were diagnosed with AH and ETD participated in this study. The mean age was 7.73 ± 2.37 (4–14 years). The rates of adenoid tissue hypertrophy and choanal occlusion were evaluated using a rigid pediatric nasal endoscope and reassessed after 3 months of Aze-Flu nasal spray treatment. The function of the Eustachian tube (ET) was evaluated before and after medical treatment using the Eustachian tube score, the Eustachian dysfunction test-7 (ETS-7) and tubomanometry (TMM). Results The results were evaluated in 100 patients with AH and ETD. The adenoid tissue to choana rate was 82% before treatment and decreased to 37% after treatment. The ETS-7 test score was 6.36 before treatment and increased to 9.72 at the end of 3 months. Both the regression of the adenoid tissue and the improvement in the Eustachian function scores were statistically significant (p < 0.05). Conclusions AH significantly increases the frequency of ETD. In this study, it was observed that Aze-Flu treatment was significantly effective in both regression of the adenoid tissue and Eustachian tube dysfunction. We believe that it can be applied as an initial therapy in children with AH and associated ETD.

Introduction: This study aims to investigate the prognostic significance of the pre-treatment hemoglobinred blood cell distribution width (RDW) ratio (HRR) in terms of overall survival (OS) and disease-free survival (DFS) in patients with locally advanced nasopharyngeal cancer (LANC) treated with chemoradiotherapy.Methods: Patients with LANC who attended the oncology clinic between October 2010 and June 2020 were retrospectively screened. HRR was calculated as hemoglobin (g/dL) divided by the RDW (%). Patients were assigned to either the low HRR group or the high HRR group.Results: A total of 102 patients were included in the study. The cut-off value for HRR was taken as 0.97. Between the low and high HRR groups, mean age, Eastern Cooperative Oncology Group (ECOG) performance score, gamma-glutamyl transferase (GGT), albumin and lactate dehydrogenase (LDH) levels, weight loss at diagnosis, and recurrence and metastasis rate were significantly different. In the low HRR group, OS and DFS were 44.4 (95% CI: 4.9-83.8) and 15.7 months (95% CI: 0.1-36.2), respectively, but could not be reached in the high HRR group (p<0.001). In the multivariate analysis, low HRR was shown to be an independent factor in terms of both OS (p=0.004, hazard ratio (HR)=3.07, 95% CI: 1.444-6.529) and DFS (p<0.001, HR=3.94,.Conclusion: This is the first study showing that HRR is an independent prognostic marker for OS and DFS in patients with LANC treated with chemoradiotherapy. Thus, HRR can be used as an easily applicable, inexpensive marker in clinical practice in this patient group.
