Item The Impact of Serum 25-Hydroxyvitamin D3 Levels on Allergic Rhinitis(2019) Coban, Kubra; Oz, Isilay; Topcu, Deniz Ilhan; Aydin, Erdinc; 0000-0002-1219-6368; 31569970; E-3717-2019We aimed to clarify the relation between allergic rhinitis and the serum levels of 25-hydroxivitamin D in the adult population. The study group consisted of 86 patients with allergic rhinitis who were diagnosed with the help of history of allergy, positive signs for allergy, blood samples, and positive skin prick tests; while the control group included 43 age- and sex-matched healthy volunteers with negative skin prick tests. The demographic data, medical history, findings in the physical examinations, serum levels of total immunoglobulin E (IgE) and 25-hydroxyvitamin D, and skin prick test results of the groups were noted. A total of 129 patients fulfilling the necessary criteria were enrolled. The median serum 25-hydroxyvitamin D levels in the study group were significantly lower compared to the control group (P= .014). In the study group, median serum vitamin D levels were significantly higher in men, compared to women (P= .03). There was a significant negative correlation between IgE and vitamin D levels in the allergic rhinitis group (P= .028,r= -0.246). This study showed that patients with allergic rhinitis might be more vulnerable to have lower serum levels of vitamin D. Thus, vitamin D supplementation as an adjunctive therapy may be considered in those patients.Item Effect of Body Mass Index on Middle Ear Resonance Frequency(2018) Sozen, Miray; Oz, Isilay; Erbek, Selim; 29460823OBJECTIVE: Multifrequency tympanometry (MET) analyzes tympanograms obtained using different probe tones between 226 and 2000 Hz. An important parameter of MET is resonance frequency (RF). Studies have recently demonstrated that the RF value can vary depending on many factors. To provide new data regarding MET, middle ear RF values were investigated with regard to body mass index (BMI). MATERIALS and METHODS:This study included 78 volunteers (i.e., 156 ears) aged 18-40 years who did not have healing loss and whose otoscopic examinations were normal. Hearing thresholds were measured using pule tone audiometry, and RF values were recorded with immitansmetric measurements. The participants were divided into the following three groups according to their BMI: <18.5 kg/m2, Group 1; 18.5-24.9 kg/m(2), Group 2; and >25 kg/m(2), Group 3. The RE values were also analyzed. RESULTS: Although there was no significant difference between Groups 1 and 2 in terms of RF values, a significant difference was observed between Groups 1 and 3 and between Groups 2 and 3. CONCLUSION: In the light of these data, BMI values should be considered when middle ear RF values are assessed.
