Investigation of central auditory processing performance in individuals with and without stuttering.

Background: Differences in core auditory processing abilities, such as sound timing, frequency discrimination, auditory perception, and auditory memory, have been suggested in stutterers, despite the fact that the precise origin of stuttering is not entirely understood. It is suggested that these differences may play a role in the development of stuttering. The aim of our study is to assess the temporal central auditory processing performance in individuals with stuttering and compare it to individuals without stuttering to uncover potential differences stuttering and compare it to individuals without stuttering to reveal potential differences.

Multi-feature mismatch negativity: How can reliable data be recorded in a short time?

Objective: The aim of the study was to conduct multi-feature mismatch negativity (MMN) implementations and identify via a test-retest study the reliability of MMN responses obtained through a 5-stimulus version of the MMN paradigm. It was also aimed to identify a reliable MMN recording number by comparing the MMN responses obtained under conditions of ten and four recordings conditions while making the recording time shorter.

Methods: Twenty-one healthy volunteers, aged between 18 and 36 years, were included in the study.

Features of unilateral hearing loss detected by newborn hearing screening programme in different regions of Turkey.

Objective: Newborn hearing screening (NHS) works well for babies with bilateral hearing loss. However, for those with unilateral loss, it has yet to be established some standard rules like age of diagnose, risk factors, hearing loss degree. The aim of this study is to identify the demographic characteristics of newborns with unilateral hearing loss to obtain evidence based data in order to see what to be done for children with unilateral hearing loss (UHL).

The effects of tinnitus and/or hearing loss on the Symptom Checklist-90-Revised test.

Objective: This study aims to evaluate the psychological attitudes of patients with tinnitus by using The Symptom Checklist-90-Revised and to investigate the relationship between hearing loss and attributed psychological attitudes.

Materials And Methods: 142 subjects (73 female, 69 male) divided into 4 groups: Group 1 (32 patients with tinnitus and hearing loss-), Group 2 (38 patients with tinnitus), Group 3 (36 patients with hearing loss), Group 4 (36 healthy subjects without tinnitus and hearing loss-control group). The Symptom Checklist-90-Revised (SCL-90-R) test was used to detect the subjects' tendency for psychological problems due to tinnitus and/or hearing loss.

Multicentre investigation on electrically evoked compound action potential and stapedius reflex: how do these objective measures relate to implant programming parameters?

Objectives: The aims of this study were to collect data on electrically evoked compound action potential (eCAP) and electrically evoked stapedius reflex thresholds (eSRT) in HiResolution(TM) cochlear implant (CI) users, and to explore the relationships between these objective measures and behavioural measures of comfort levels (M-levels).

Methods: A prospective study on newly implanted subjects was designed. The eCAP was measured intra-operatively and at first fitting through neural response imaging (NRI), using the SoundWave(TM) fitting software.

The applications have been done in University of Freiburg, Cochlear Implant Center in Germany, and University of Hacettepe, ENT Department, Audiology and Speech Pathology Section in Turkey.

Depressive emotioning in adolescents with cochlear implant and normal hearing.

Objective: The purpose of this study is to compare the levels of depressive emotioning of adolescents with cochlear implants and the ones who have normal hearing.

Methods: For this purpose, Rosenberg Self-Esteem Scale is applied upon the study group which consists of 30 adolescents with cochlear implant between the ages of 12-19 and upon the control group which consists of 60 adolescents having the similar characteristics. The scale is used to evaluate the level of depressive emotioning of adolescents with cochlear implant and with normal hearing.

Preliminary results of auditory brainstem implantation in prelingually deaf children with inner ear malformations including severe stenosis of the cochlear aperture and aplasia of the cochlear nerve.

Objective: The aim of our study is to present the results of 11 children where auditory brainstem implantation (ABI) was successfully performed to restore hearing.

The family oriented musical training for children with cochlear implants: speech and musical perception results of two year follow-up.

Objective: The purpose of this study is to determine whether children can gain benefit from training on pitch and music perception. Our main goals were to prepare a tool for training pitch and rhythm perception and evaluate musical attitude in children, to determine whether pitch and rhythm perception improve more rapidly through training and to assess the impact of training on speech perception.

Method: A family centred habilitation program based on musical training is developed.

[Evaluation of high frequency hearing thresholds in smokers].

Objectives: We investigated whether high frequency hearing thresholds differed between smokers and nonsmokers.

Subjects And Methods: The study was carried out in 50 individuals including 20 nonsmokers (mean age 29 years; range 25 to 37 years) and 30 smokers (mean age 34 years; range 25 to 50 years).

Long-term effects of dexamethasone on hearing ability in children with pneumococcal meningitis.

Controlled trials concerning adjuvant dexamethasone therapy in bacterial meningitis do not point unequivocally to a beneficial effect on hearing ability. We investigated the remote adverse outcomes of pneumococcal meningitis and, if any, beneficial effects of adjuvant dexamethasone therapy on hearing ability. Fifty-five subjects who experienced pneumococcal meningitis between 1987-97 were divided into two groups as 25 subjects who did not receive dexamethasone (Group 1) and the remaining 30 subjects who did (Group 2).

Hearing loss in biotinidase deficiency: genotype-phenotype correlation.

Children with symptoms of profound biotinidase deficiency with null mutations are more likely to have hearing loss develop than those with missense mutations, even if not treated for a period of time. Hearing loss appears to be preventable in children with null mutations if treatment is initiated soon after birth.
