Background Intranasal phototherapy offers an alternative treatment method for patients with allergic rhinitis who cannot benefit from intranasal corticosteroids and oral antihistamines. Different wavelengths have been tried with promising results. Objective In this present study, we aimed to investigate the effects of visible light-infrared light phototherapy on clinical improvements together with its cytologic effects in patients with allergic rhinitis. Methods Patients with confirmed allergic rhinitis were given a 4-week course of intranasal phototherapy treatment. Weekly symptom questionnaires were applied to monitor clinical effects. Nasal lavage specimens were obtained before the start and at the completion of the 4-week therapy. Fluorescence-activated cell sorting analyses of CD16+, CD24+, and CD 45+ cells were performed. Statistical analyses are performed of weekly changes in symptoms and cell counts. Results CD45+CD16highCD24+ neutrophil count in nasal lavages decreased significantly whereas CD45+CD16dim/−CD24+ eosinophil counts significantly increased and CD45+ granulocyte counts remained unchanged. Symptom scores including nasal itching, nasal discharge, nasal obstruction, sneezing, eye itching, throat itching, and ear itching all statistically decreased compared to baseline at the end of 4 weeks. Conclusion Four-week course of intranasal phototherapy with visible and infrared light leads to clinical improvement in allergic rhinitis patients.
Context:
Hyperinsulinemia is the most common metabolic change associated with cochleovestibular diseases.
Aim:
We aimed to investigate the auditory functions in hyperinsulinemic individuals.
Settings and Design:
A total of 164 patients were included in this case-control study. While 76 patients with insulin resistance (homeostasis model assessment of insulin resistance [HOMA-IR] of ≥2.5) constituted the case group, 88 patients with HOMA-IR values of <2.5 constituted the control group of the study.
Material and Methods:
The 75 g oral glucose tolerance test, blood biochemistry tests, hormonal analysis, audiological assessment, electrocochleography (EcochG), and transient evoked otoacoustic emissions (TEOAE) testing were performed.
Statistical Analysis:
One-way analysis of variance and Kruskal–Wallis analysis of variance were used for the comparison of the metabolic and ear parameters in the normal glucose tolerance (NGT), impaired fasting glucose (IFG), and impaired glucose tolerance (IGT) groups. The chi-square test was used to compare nominal variables. Spearman and Pearson correlation coefficients were used for the correlation analyses of continuous variables.
Results:
The pure tone audiometry at 0.5, 1, 2, and 4 kHz was better in the case group than in the control group. A positive correlation was found between HbA1c and right ear 0.5, 1, 4, and 8 kHz threshold values and left ear 2, 4, 6, and 8 kHz threshold values. A negative correlation was found between HbA1c and speech discrimination scores. The right ear 1.00 and 2.83 kHz TEOAE measurements in the individuals with NGT were found higher than those in patients with IGT, and the 1.42 kHz TEOAE measurements and reproducibility were found higher than those in patients with IFG. The left ear 1.00 and 1.42 kHz TEOAE measurements of the IGT patients were found lower than those of IFG and NGT patients.
Conclusion:
We showed that hearing was worsening in hyperinsulinemic patients and prediabetic conditions were related to hearing function impairment.
Video head impulse test (vHIT) is commonly used for the evaluation of vestibular system disorders because it can be performed easily in a short period of time. However, there is no diagnostic value to vHIT alone. Patient history and examination findings con-tribute the most important information in the diagnosis of vestibular disorders and in some pathologies such as benign paroxysmal positional vertigo (BPPV) and Meniere's disease, a correct diagnosis can generally be made with a limited number of laboratory
