Öğe Are newborn intensive care units suitable for hearing screening?(Cocuk Sagligi ve Hastaliklan Dergisi muratyurdakok@yahoo.com, 2016) Kaya, Mesut; Unsal, Selim; Yilmaz, Ceyda Sel; Genç, Meltem; Turan, Selma; Gündüz, MehmetTo evaluate the noise levels in the neonatal intensive care unit and discuss their suitability for neonatal hearing screening environment, a descriptive cross-sectional study was carried out in nine neonatal intensive care units in Bursa during June 2015. Sound intensity level measurements were recorded each 10 seconds for 15 minutes, at 1 hour before, during and 1 hour after breastfeeding of neonates between 8 am and 5 pm. Recordings showed that the sound levels of all ICUs of nine hospitals are above 40 dB, the limits of National Noise Regulation Standards. Our study reveals that neonatal intensive care unit environment is not suitable for neonatal hearing screening test administration; with false positive results. This may cause adverse effects on family, the physicians and national economy. © 2017 Elsevier B.V., All rights reserved.Öğe Correlation of o-VEMP and v-HIT Test Results with Caloric Test Results iSn Peripheral Vestibular Disorders(Aves, 2017) Ozdek, Ali; Keseroglu, Kemal; Er, Serap; Unsal, Selim; Gunduz, MehmetObjective: To investigate the correlation of ocular vestibular evoked myogenic potential (o-VEMP) and video head impulse (v-HIT) test results with caloric test results in peripheral vestibular disorders, and to define an algorithm for investigating vestibular disorders. Methods: All patients underwent an ENT physical examination, an MRI scan, videonystagmography, an o-VEMP test, and a v-HIT test. The patients who had central-type vertigo, PBBV, and vestibular migraine were excluded from the study. Overall, 30 patients were included in the study. Results: Canal paralysis was observed in 22 patients (73.3%). Pathological o-VEMP and v-HIT test results were obtained in 19 (63.3%) and 8 (26.7%) patients, respectively. Pathological o-VEMP or v-HIT was observed in 17 of 22 (77.3%) patients with canal paralysis. Sensitivity and specificity of a combination of o-VEMP and v-HIT test results for detecting canal paralysis were 77.3% and 80.1%, respectively. Conclusion: It does not seem that o-VEMP and v-HIT tests can replace the caloric test to detect vestibular hypofunction. However, these two tests can be used as first-line tests to initiate vestibular evaluation. If one of these two tests shows vestibular hypofunction, there is no need to perform a caloric test.Öğe Does Tinnitus Lead to Depression?(Canadian Soc Clinical Investigation, 2016) Temugan, Esra; Yildirim, Rabia B.; Onat, Humeyra; Susuz, Merve; Elden, Cemre; Unsal, Selim; Gumus, Nebi MustafaPurpose: The aim of the study was to investigate the correlation between THI (Tinnitus Handicap Inventory) and BDS (Beck Depression Scale). Materials and Methods: High frequency thresholds and PTA (Pure Tone Audiometer) thresholds for the patients were measured in 44 patients with tinnitus (bilateral= 13; unilateral= 31). Tinnitus frequency and intensity were measured using one-pair method with high frequency audiometer Interacoustic AC40. Applied BDS and THI scores are evaluated for all patients. Our findings are analysed statistically with SPSS v. 21 and BDS and THI correlation with tinnitus intensity and frequency was executed. Results: The mean value of tinnitus frequency was 10 kHz (min 0.25 kHz, max16 kHz and SD 4.26), mean tinnitus intensity was 50.6 dB (min 15 dB, max 110 dB and SD 26.9 dB) mean THI score was 38.04 (min 10, max 86 and SD 20.03) and mean BDS score was 9.45 (min 0, max 28 and SD 6.49). There was no statistical correlation between THI score and tinnitus frequency (r= 0.055, p= 0.787). Moderate correlation is obtained between tinnitus frequency and depression (r= 0.6, p= 0.001). There were weak correlations between tinnitus intensity and THI score and (r= 0.3, p= 0.09) and between tinnitus intensity and BDS score (r= 0.28, p= 0.13). Although a statistically significant difference was observed between THI scores of patients with bilateral and unilateral tinnitus (p< 0.05), BDS scores of these groups were not statistically different from each other (p> 0.05). High frequency thresholds and UCL scores of ears with tinnitus were not statistically different from ears with no tinnitus (p> 0.05). Conclusion: No correlation was seen between THI and tinnitus frequency, but a moderate correlation was seem between BDS score and tinnitus frequency. There were also weak correlations between tinnitus intensity and THI and BDS scores.Öğe Evaluation of Acoustic Reflex and Reflex Decay Tests in Geriatric Group(Galenos Yayincilik, 2016) Unsal, Selim; Karatas, Havva; Kaya, Mesut; Gumus, Nebi Mustafa; Temugan, Esra; Yuksel, Mustafa; Gunduz, MehmetObjective: To determine average acoustic reflex thresholds in geriatric groups by assessing ipsilateral and contralateral acoustic reflex and reflex decay tests. Methods: A total of 25 elders between ages 65-84 years (74.3 +/- 5.4) and 25 individuals between ages 18-45 years (30.4 +/- 4.2) were recruited for the study. After ear, nose, and throat examination, ipsilateral and contralateral acoustic reflex thresholds at 500, 1000, 2000, and 4000 Hertz (Hz) were determined and a reflex decay test at contralateral 500 Hz was conducted. Ipsilateral acoustic reflex thresholds were obtained with high-frequency band, low-frequency band, and wide band noise, and the results were compared with ipsilateral acoustic reflexes at 500, 1000, 2000, and 4000 Hz. Results: There was no statistically significant difference between the two groups in ipsilateral and contralateral acoustic reflex measurements at 500, 1000, 2000, and 4000 Hz (p>0.05). Negative reflex decay was obtained in all participants and no statistically significant difference between the two groups was observed in terms of reflex decay thresholds (p>0.05). Acoustic reflex with high-frequency band noise was observed in five of nine elders whose acoustic reflexes were not obtained at 2000 and 4000 Hz, whereas acoustic reflex with low-frequency band noise was observed in one of six elders who did not show reflexes at 500 and 1000 Hz. Conclusion: It was concluded that although some changes were observed due to age, middle ear and stapes muscles work normally in geriatric group. In the reflex decay test, reliable results were obtained at contralateral 500 Hz. Acoustic reflex measurements with low-and high-frequency band noise may also be used to assess middle ear functions.Öğe Evaluation of eustachian tube function tests and immitancemetric measurements in a geriatric group(Geriatrics Society, 2016) Unsal, Selim; Yaman, Ünzile; Gümş, Nebi Mustafa; Kaya, Mesut; Temügan, Esra; Gecin, Mustafa Vecdi; Yüksel, Mustafa T.Introduction: Atrophy in the middle ear and degeneration of muscle fibers, fibrous tissue ligament, and bone as well as calcification of Eustachian cartilage occurs with aging. We aimed to evaluate the middle ear system and changes in Eustachian tube functions in a geriatric group. Materials and Method: Study participants comprised 30 older and 30 younger individuals between the age of 65 and 84 years (74.3±5.4 years) and 18 and 45 years (30.4±4.2 years), respectively. All participants underwent immitancemetric measurements and Eustachian tube function tests after ear, nose, and throat examination. For the immitancemetric measurements, the ear canal volume, compliance, middle ear pressure, and gradient were evaluated. Valsalva and Toynbee maneuvers were used to perform the Eustachian tube function tests. Results: Non-significant differences were found between the two groups for the ear canal volume and middle ear pressure (p>0.05). While no significant difference was found for the left ear compliance values between the two groups (p>0.05), a significant difference between the left ear compliance and gradient values for both ears was found (p<0.05). Eustachian tube function tests showed no significant differences between the groups, based on the values obtained by Valsalva and Toynbee maneuvers. Conclusion: Eustachian tube functions in the geriatric group were found to be normal in this study. Bilateral gradient and right ear compliance values were higher in the geriatric group than in the control group indicating that the middle ear system in the geriatric group was more active. © 2017 Elsevier B.V., All rights reserved.Öğe Examination of Insert Ear Interaural Attenuation (IA) Values in Audiological Evaluations(Canadian Soc Clinical Investigation, 2016) Gumus, Nebi M.; Gumus, Merve; Unsal, Selim; Yuksel, Mustafa; Gunduz, MehmetPurpose: The purpose of this study was to evaluate Interaural Attenuation (IA) in frequency base in the insert earphones that are used in audiological assessments. Methods: Thirty healthy subjects between 18-65 years of age (14 female and 16 male) participated in our study. Otoscopic examination was performed on all participants. Audiological evaluations were performed using the Interacoustics AC40 clinical audiometer and ER-3A insert earphones. IA value was calculated by subtracting good ear bone conduction hearing thresholds of the worst airway hearing threshold. Results: In our measuring for 0.125-8.0 kHz frequency were performed in our audiometry device separately for each frequency. IA amount in the results we found in 1000 Hz and below frequencies about 75-110 dB range avarage is 89 +/- 5dB, in above 1000 Hz frequencies in 50-95 dB range and avarage it is changed to 69 +/- 5dB. Conclusion: According to the obtained findings the quantity of melting in the transition between the ears are increasing with the insert earphones. The insert earphone should be beside supraaural earphone that is routinely used in clinics. Difficult masking applications due to the increase in the value of IA can be easily done with insert earphones.Öğe Examination of insert ear interaural attenuation (IA) values in audiological evaluations(The Canadian Society for Clinical Investigation, 2016) Gumus, Nebi Mustafa; Gumus, Merve; Unsal, Selim; Yüksel, Mustafa T.; Gündüz, MehmetPurpose: The purpose of this study was to evaluate Interaural Attenuation (IA) in frequency base in the insert earphones that are used in audiological assessments.

Materials and Methods: This study was conducted on 21 Wistar albino rats in four groups. Cisplatin, cisplatin plus NAC, NAC alone, and saline were intraperitoneally administered. The rats were anesthetized to study the otoacoustic emissions before and after the experiment. Results: The OAEs were attenuated in the cisplatin group: (-1.31/-4.90), (6.28/4.58), (4.00/0.93), (2.73/-3.74), (2.66/-4.53). The group that received NAC in addition to cisplatin had better OAEs. Conclusion: Cisplatin ototoxicity can be detected by OAE testing in rats, and NAC may reduce the ototoxic effect.Öğe Research on articulation problems of Turkish children who have Down syndrome at age 3 to 12(Walter de Gruyter GmbH info@degruyter.com, 2017) Ongun, Mehmet; Gumus, Nebi Mustafa; Unsal, Selim; Yildirim, Ali; Yüksel, Sevda; Yüksel, Mustafa T.; Gunduz, MehmetArticulation is a process that allows air to pass through vocal cords and then form words and syllables using the tongue, teeth, mentum and palatine tonsils. A person who has pronunciation problems produces, syllables or words inaccurately so; the auditoria have got difficulty to understand what did say, such that the listener has difficulty in understanding what is being said. Due to being genetically different the Down syndrome individual has difficulty with speech due to structural defects in the mouth and problems with the mouth-tongue muscles. Here the determination of the articulation (pronunciation) problems and the probable causes of the determined problems have been studied. This study involved children without hearing loss problems; 17 females and 23 males who have Down syndrome and were ages between 3 and 12 years. The Ankara articulation test (AAT) was applied to the individuals. The articulation (pronunciation) ages have been determined according to the ATT. By the detailed assessment of the ATT, it was determined which voices were uttered correctly or not. Through a family interview survey, the information that affected the development of the Down syndrome child's speech and academic development was obtained. Through a patient identification survey, the education and health information that may effect the speech development were obtained. Through an oral motor assessment survey, the information regarding the competence of oral motor skills that may effect articulation problems were collected. The data were analyzed. Using a family survey, child identification survey and an oral motor assessment survey the correlation between articulation age and articulation defects were viewed. It has been detected that the articulation age of Down syndrome children between 3 and 12 years of age are quite a bit lower when compared to the chronological age according to the ATT. Moreover, in terms of results from the ATT, children with Down syndrome whose cronological age is 8 years 7 months have a 3 year 5 months' articulation age according to the ATT. They have some difficulties with Turkish vowels such as (/a/, /e/, /l/, /i/). Also they have some difficulties with consonants such as (/r/, /j/, /z/, /ş/, /z/, /l/, /s/, /n/). Articulation defects at various levels have been detected for all Down syndrome children. Articulation (pronunciation) problems were encountered less in children from highly educated and more concerned families. It has been shown that articulation (pronunciation) problems are less children who receive early treatment, therapy and education services. Significant correlation between the level of articulation usage by individuals and frequency of the articulation problem were detected. For this reason, attaching importance to oral motor studies are considered. Raising parental awareness is required on prenatal diagnosis of Down syndrome. By treating the problems of the speech organs at an early age and including the children who have Down syndrome into the early education programs around 0-3 years and accurate intervention during critical periods, the articulation problems can be reduced. Using a wider age range and having more participants, it is considered that more efficient results may be obtained. © 2017 Elsevier B.V., All rights reserved.Öğe Research on the relationship between articulation levels and social skills of Turkish children between the ages of 4 and 5 years(Walter de Gruyter GmbH info@degruyter.com, 2017) Gumus, Nebi Mustafa; Eryilmaz, Sevil; Unsal, Selim; Yildirim, Ali; Yüksel, Sevda; Yüksel, Mustafa T.; Gunduz, MehmetThis study aims to investigate whether there is a relationship between articulation levels and social skills of normally developing children at the ages of 4 and 5 years and to determine whether articulation levels and social skills are differentiated with regard to variable factors. A relational screening model was used in this study. Eighty-seven boys and 73 girls (160 children in total) who were educated at four preschools were selected according to simple random sampling in Kütahya province, Turkey. The mean age of the children was 4.6 years. The Ankara Articulation Test (AAT) was used to specify the articulation levels of children and the Preschool Social Skills Rating Scale [PSSRS, Okul Öncesi Sosyal Beceri De?erlendirme Ölçe?i (OSBED)] was used to evaluate the social skills of the children. The results of the study revealed that the articulation mistakes decrease and social skills increase as the age of children rises. It was found that girls had better results in both social skills and articulation levels than boys. Analysis of the socio-economic statuses of the children showed no significant differences between articulation levels and social skills. Correlation analysis showed that children with articulation disorders have lower social skills rankings than children without articulation disorders, and speech is one of the factors that affect social skills ranking. This study is important because of its observations about speech, communication, and social skills in children, as well as for raising awareness among parents and teachers of preschool children. © 2017 Elsevier B.V., All rights reserved.Öğe Retrospective air bone gap evaluation of patients with tympanic membrane central perforation(Canadian Soc Clinical Investigation, 2016) Kucukkavruk, Levent; Temugan, Esra; Kaya, Mesut; Unsal, Selim; Gumus, Nebi Mustafa; Yuksel, Mustafa; Gunduz, MehmetPurpose: The purpose of this study was to evaluate hearing recovery and air-bone gap (ABG) before and after tympanoplasty surgery in patients with tympanic membrane central perforation. Methods: Histories and audiological assessments of 160 cases (total of 26 ears from 22 patients; 11 men and 11 women) from patients who had undergone tympanoplasty surgery and hearing reconstruction due to tympanic membrane central perforation were evaluated. Pre-postoperative audiograms and the pure tone, air-bone hearing thresholds and ABG gains were evaluated. Results: The mean age of the patients was 38.6 years (+/- 16.04). The mean postoperative follow-up period was 13.4 months (+/- 15.5). The mean preoperative ABG was 25.36 dB (+/- 9.9) and postoperative ABG was 17.36 dB (+/- 11.68) (p = 0.001). When four groups were compared before surgery and after surgery period as 0-6 months, 6-12 months, 1-2 years and 2 years in terms of pre-and postoperative ABG values, no statistically significant difference was observed (p>0.05). All patients were divided into three groups: < 20 years of age; between the ages of 21-40; and, > 41 years of age, and no statistically significant difference were found between the groups (p>0.05). Surgeries of the patients 21-40 years of age were more successful (ABG gain) than other age groups. No statistically significant gender differences were found in ABG averages (p = 0.33), but clinical results were significantly better in women as compared with men. Conclusion: In patients with central tympanic membrane perforation, tympanoplasty surgery with temporal fascia is beneficial in terms of hearing recovery.
