Öğe Does SARS-CoV-2 affect cochlear functions in children?(Saudi Med J, 2022) Koca, Cigdem F.; Celik, Turgut; Simsek, Agit; Aydin, Sukru; Kelles, Mehmet; Yasar, Seyma; Erdur, OmerObjectives: To determine the influence of coronavirus disease-19 (COVID-19) on cochlear tasks of children who had COVID-19 previously, and the relevance among disease seriousness and cochlear involvement by otoacoustic emissions (OAEs). Methods: The study included 24 hospitalized children after COVID-19 diagnosis, 23 pediatrics that received outpatient treatment, and 21 children who were without COVID-19 diagnosis as the control group between June 2021 and July 2021. Transient evoked otoacoustic emission ( TEOAE), distortion product otoacoustic emission, and contrlateral suppression of otoacoustic emission measurements were carried out for each child. Symptoms of patients, the treatments they received, and the duration of hospitalization of the children in the hospitalized group were recorded. Results: The comparison of TEOAE test results under masking showed a considerable difference between 3 groups at 1 kHz (p=0.033) and 4 kHz (p=0.021) frequencies (p<0.05). Distortion product otoacoustic emission test results of hospitalized outpatient and control group showed a statistically significant difference at 2 kHz among themselves (p=0.009). Conclusion: Our results suggest that severe acute respiratory syndrome coronavirus-2 may influence the medial olivocochlear system of children and have irreversible effects on the cochlear functions. Early detection of problems that may affect cochlear functions is a special critical task, especially in children, who are a particularly vulnerable group in terms of hearing and related speech problems.Öğe Evaluation of cochlear functions in infants exposed to SARS-CoV-2 intrauterine(W B Saunders Co-Elsevier Inc, 2021) Celik, Turgut; Simsek, Agit; Koca, Cigdem Firat; Aydin, Sukru; Yasar, SeymaPurpose: The novel coronavirus (SARS-CoV-2) caused an acute respiratory illness named COVID-19 and the disease spread all over the World. Fever, cough, fatigue, gastrointestinal infection symptoms form the main clinical symptoms. Pregnants and newborns form a vulnerable population and urgent measures must be addressed. Studies about the effect of COVID-19 on pregnant women, developing fetuses, and infants are limited. Various viral diseases can cause congenital or acquired, unilateral or bilateral hearing loss. Methods: 37 infants whose mother was pregnant between March 2020 and December 2020 and were born after the diagnosis of COVID- 19 during pregnancy and 36 healthy infants were included in the study. Transient evoked otoacoustic emission (TEOAE), distortion product otoacoustic emission (DPOAE) and contralateral suppression of OAE (CLS OAE) tests were performed on all infants. Results: According to the TEOAE results of patients and controls in the silent a statistically significant difference was observed between the two groups at 3 kHz and 4 kHz (p < 0.05). Contralateral suppression of OAE test results of patients and controls a statistically significant difference was found in all frequencies (p< 0.05). Suppression was much more effective at all frequencies in the normal group than patient group. This difference was found to be more significant at higher frequencies (2,3 and 4 kHz) (p < 0.001). Conclusions: Our results suggest an insufficiency in medial olivocochlear efferent system in infants exposed to SARS-CoV-2 intrauterine. Cochlear functions should be examined in infants whose mothers had COVID-19.Öğe Evaluation of the auditory findings of patients with obstructive sleep apnea syndrome(W B Saunders Co-Elsevier Inc, 2024) Simsek, Agit; Aslan, MehmetObjectives: To investigate the effects of hypoxia occurring in patients with Obstructive Sleep Apnea Syndrome (OSAS) on Auditory evoked late latency, Auditory brainstem response, and the contralateral suppression of otoacoustic emissions.Materials and methods: 46 patients diagnosed with OSAS were divided into groups as moderate and severe based on their Apnea Hipopnea Index (AHI) values. The control group consisted of 22 healthy individuals. All participants underwent an Auditory Brainstem Response (ABR) test, Auditory Evoked Late Latency Response (LLR), and Contralateral Suppression Otoacoustic Emission (CS-OAE).Findings: There was no statistical difference between the OSAS group and the control group regarding P1 latency, N1 latency, and P1 and N1 wave amplitude (p > 0.05). In ABR, statistically significant differences were found between the control, moderate OSAS, and severe OSAS groups in wave I in the right and left ear (p < 0.05). In the analyses performed for the otoacoustic emission frequencies with and without contralateral suppression of the right and left ear, suppression was not observed at some frequencies, and this was regarded as statistically significant (p < 0.05).Conclusion: It is considered that OSAS does not have cortical effects but impacts the brainstem region and the cochlea. Bilateral impact, especially observed in wave I of ABR, is prominent on the auditory nerve. Considering that the medial olivo-cochlear (MOC) system is affected in patients with OSAS, it is thought that these patients are inadequate in suppressing noise, and this may cause various problems, particularly the inability to distinguish speech in noisy environments.Öğe Multivariate Analysis of the Factors Affecting Tinnitus Severity in Old Age: A Multi-Center Cross- Sectional Study(Gazi Univ, Fac Med, 2023) Ozer, Fulya; Cabuk, Goezde Bayramoglu; Mutlu, Meryem; Er, Serap; Simsek, Agit; Erbek, Selim SermedAim: The purpose of this study was to analyze the factors affecting tinnitus severity in the population aged 60 and over with a multi-central data and with multivariate analysis. Materials: This prospective study was composed of 130 subjects aged 60 years or older with clinical complaint of tinnitus and administered to five different otorhinolaryngology clinics in four different cities in our country. All participants have been tested with pure tone audiometry. Tinnitus loudness and pitch mapping were determined for all participants. All participants also interviewed individually to complete Tinnitus Handicap Inventory (THI) and asked to characterize their tinnitus symptoms using a visual analog scale (VAS) measuring severity, annoyance of tinnitus. Results: Tinnitus loudness increases significantly in the group over the age of 79, but there is no significant difference between the groups formed according to age in terms of VAS or THI values. Systemic disease does not make a significant difference that increases the severity of tinnitus. risk factors that increase tinnitus severity are included in the logistic regression analysis; High level of education and advanced age over 79 years were determined as independent risk factors. Increasing education level is an independent risk factor for increasing tinnitus severity with an odds ratio of 2.46 (95% CI, 1.080-5.624). At the same time, advanced age over 79 years is an independent risk factor with an odds ratio of 5.4 (95% CI, 1,385-21.197), which causes tinnitus severity to be felt more. Conclusion: In old age population, the incidence of tinnitus does not increase with increasing age, but tinnitus severity increases. As hearing loss increases, tinnitus severity and VAS score increase. According to the results of this study, the most important risk factors that increase the perception of tinnitus in the elderly population were determined as very advanced age and high education level. It is reasonable to think that one of the reasons for this is that the elderly in the vulnerable group for the Covid 19 pandemic should stay away from hospitals unless their tinnitus complaints are very serious. Re-performing our study in elderly individuals after the pandemic is important to see the effect of the pandemic period more clearly in these individuals.
