OBJECTIVE: To demonstrate the long-term benefits of implantation in patients with high-frequency sensorineural hearing loss, this report provides 5-year follow-up on a group of implant recipients who were subjects of the Cochlear™ Nucleus® Hybrid™ L24 Implant System pivotal clinical study. METHODS: The results of three related clinical studies were compiled to provide outcome data after 1, 3, and 5 years of implant use in a group of subjects who presented with preoperative high-frequency hearing loss and were implanted with a Nucleus Hybrid L24 (Cochlear Ltd...

PURPOSE: The aim was to determine inpatient treatment rates of idiopathic sudden sensorineural hearing loss (ISSNHL) with focus on diagnostics, treatment, and outcome. METHODS: A retrospective population-based study in the federal state Thuringia in 2011 and 2012 was performed on all 490 inpatients (51% females, median age: 60 years) treated for ISSNHL (Median duration: 7 days). The association between analyzed parameters and the probability of recovery was tested using univariable and multivariable statistics...

Attacks by aquatic predators generate frontal water disturbances characterised by low-frequency gradients in pressure and particle motion. Low-frequency hearing is highly developed in cephalopods. Thus, we examined behavioural responses in juvenile cuttlefish to infrasonic accelerations mimicking main aspects of the hydrodynamic signals created by predators. In the experimental set-up, animals and their surrounding water moved as a unit to minimise lateral line activation and to allow examination of the contribution by the inner ear...

BACKGROUND AND OBJECTIVES: It is important to understand the frequency region of cues used, and not used, by cochlear implant (CI) recipients. Speech and environmental sound recognition by individuals with CI and normal-hearing (NH) was measured. Gradients were also computed to evaluate the pattern of change in identification performance with respect to the low-pass filtering or high-pass filtering cutoff frequencies. SUBJECTS AND METHODS: Frequency-limiting effects were implemented in the acoustic waveforms by passing the signals through low-pass filters (LPFs) or high-pass filters (HPFs) with seven different cutoff frequencies...

Sonia is a 4 1/12-year-old girl with Waardenburg syndrome and bilateral sensorineural hearing loss who had bilateral cochlear implants at 2 7/12 years of age. She is referred to Developmental-Behavioral Pediatrics by her speech/language pathologist because of concerns that her language skills are not progressing as expected after the cochlear implant. At the time of the implant, she communicated using approximately 20 signs and 1 spoken word (mama). At the time of the evaluation (18 months after the implant) she had approximately 70 spoken words (English and Spanish) and innumerable signs that she used to communicate...

BACKGROUND: Hearing screening tests based on pure-tone audiometry may be conducted on mobile devices, provided that the devices are specially calibrated for the purpose. Calibration consists of determining the reference sound level and can be performed in relation to the hearing threshold of normal-hearing persons. In the case of devices provided by the manufacturer, together with bundled headphones, the reference sound level can be calculated once for all devices of the same model. OBJECTIVE: This study aimed to compare the hearing threshold measured by a mobile device that was calibrated using a model-specific, biologically determined reference sound level with the hearing threshold obtained in pure-tone audiometry...

The prevalence and spectrum of sequence alterations in the SLC26A4 gene, which codes for the anion exchanger pendrin, are population-specific and account for at least 50% of cases of non-syndromic hearing loss associated with an enlarged vestibular aqueduct. A cohort of nineteen patients from Austria with hearing loss and a radiological alteration of the vestibular aqueduct underwent Sanger sequencing of SLC26A4 and GJB2, coding for connexin 26. The pathogenicity of sequence alterations detected was assessed by determining ion transport and molecular features of the corresponding SLC26A4 protein variants...

BACKGROUND: Despite ongoing advances in the treatment of mood disorders, a substantial proportion of people diagnosed with major depression or bipolar disorder remain symptomatic over time. Yoga, which has been shown to reduce stress and depressive symptoms, as well as to improve overall quality of life, shows promise as an adjunctive treatment. However, dissemination of yoga for clinical populations remains challenging. The purpose of this pilot study was to test the feasibility and acceptability of an online yoga intervention for individuals with mood disorders...

Infection caused by Varicella zoster virus (VZV) is a common etiology of acute peripheral facial palsy (APFP). We aimed to assess the clinical significance of detecting VZV DNA from the saliva of patients with APFP. Saliva collected from thirty-six patients with unilateral APFP at initial visit was analyzed to detect VZV DNA by polymerase chain reaction. The House-Brackmann (HB) scale was used to evaluate FP severity on admission day, at week 2, and at weeks 10-12 after start of treatment. Among the 28 patients without rash, VZV DNA was detected in 3 patients (10...

Olivier Valentin, Frédéric Laville
INTRODUCTION: The currently available methods for measuring the occlusion effect (OE) of hearing protection devices (HPDs) have limitations. Objective microphonic measurements do not assess bone-conducted sounds directly transmitted to the cochlea. Psychophysical measurements at threshold are biased due to the low-frequency masking effects from test participants' physiological noise and the variability of measurements based on subjective responses. An auditory steady-state responses (ASSRs) procedure is used as a technique that might overcome these limitations...

Hearing and cognition are commonly involved in both normal and pathological aging. Current clinical interest lies in whether peripheral hearing loss promotes cognitive decline. In our previous publication, the authors have shown a causal relationship between hearing and cognitive impairments in C57BL/6 mice. Here we extended the follow-up to 12 months to determine the long-term effects of hearing loss on cognition and to observe hippocampal p-tau and lipofuscin. One month old male mice were randomly allocated into two groups, the control (n = 12) and noise-induced hearing loss (NIHL) (n = 12)...

OBJECTIVE: Research findings concerning the relation between benefit from hearing aid (HA) noise suppression and working memory function are inconsistent. The current study thus investigated the effects of three noise suppression algorithms on auditory working memory and the relation with reading span. DESIGN: Using a computer simulation of bilaterally fitted HAs, four settings were tested: (1) unprocessed, (2) directional microphones, (3) single-channel noise reduction, and (4) binaural coherence-based noise reduction...

Based on demographic prognoses, it must be assumed that a greater number of older workers will be found in the future labor market. How to deal with their possible age-related impairments of sensory functions, like hearing impairment and work performance during extended working time, has not been addressed explicitly until now. The study addresses this interplay. The study was performed on two consecutive days after normal working hours. The 55 participants had to "work" in the study at least three additional hours to simulate a situation of long working hours...

HYPOTHESIS: As a result of their hearing loss, adults with cochlear implants (CIs) would self-report poorer executive functioning (EF) skills than normal-hearing (NH) peers, and these EF skills would be associated with performance on speech recognition tasks. BACKGROUND: EF refers to a group of high order neurocognitive skills responsible for behavioral and emotional regulation during goal-directed activity, and EF has been found to be poorer in children with CIs than their NH age-matched peers...

OBJECTIVES: To evaluate the relationship between vestibular function and gross motor development in children with inner ear malformations. METHODS: A total of 195 children (average age: 2.4 ± 1.6 yr) with profound hearing loss, defined as a hearing threshold greater than 80 dB, participated in this study. Evaluation of vestibular function was assessed in all children using a damped rotational chair test. Gross motor development was assessed by examining the age of acquisition of head control and independent walking...
