Discussions about professional behaviors are growing increasingly prevalent across health professions, especially as a central component to education programs. A strong critical thinking disposition, paired with critical consciousness, may provide future health professionals with a foundation for solving challenging practice problems through the application of sound technical skill and scientific knowledge without sacrificing sensitive, empathic, client-centered practice. In this article, we describe an approach to monitoring student development of critical thinking dispositions and key professional behaviors as a way to inform faculty members' and clinical supervisors' support of students and ongoing curriculum development. We designed this exploratory study to describe the trajectory of change for a cohort of audiology students' critical thinking dispositions (measured by the California Critical Thinking Disposition Inventory: [CCTDI]) and professional behaviors (using the Comprehensive Professional Behaviors Development Log-Audiology [CPBDL-A]) in an audiology program. Implications for the CCTDI and CPBDL-A in audiology entry-to-practice curricula and professional development will be discussed. This exploratory study involved a cohort of audiology students, studied over a two-year period, using a one-group repeated measures design. Eighteen audiology students (two male and 16 female), began the study. At the third and final data collection point, 15 students completed the CCTDI, and nine students completed the CPBDL-A. The CCTDI and CPBDL-A were each completed at three time points: at the beginning, at the middle, and near the end of the audiology education program. Data are presented descriptively in box plots to examine the trends of development for each critical thinking disposition dimension and each key professional behavior as well as for an overall critical thinking disposition score. For the CCTDI, there was a general downward trend from time point 1 to time point 2 and a general upward trend from time point 2 to time point 3. Students demonstrated upward trends from the initial to final time point for their self-assessed development of professional behaviors as indicated on the CPBDL-A. The CCTDI and CPBDL-A can be used by audiology education programs as mechanisms for inspiring, fostering, and monitoring the development of critical thinking dispositions and key professional behaviors in students. Feedback and mentoring about dispositions and behaviors in conjunction with completion of these measures is recommended for inspiring and fostering these key professional attributes.

To present recent studies that used the ultrasound in the fields of Speech Language Pathology and Audiology, which evidence possibilities of the applicability of this technique in different subareas. A bibliographic research was carried out in the PubMed database, using the keywords "ultrasonic," "speech," "phonetics," "Speech, Language and Hearing Sciences," "voice," "deglutition," and "myofunctional therapy," comprising some areas of Speech Language Pathology and Audiology Sciences. The keywords "ultrasound," "ultrasonography," "swallow," "orofacial myofunctional therapy," and "orofacial myology" were also used in the search. Studies in humans from the past 5 years were selected. In the preselection, duplicated studies, articles not fully available, and those that did not present direct relation between ultrasound and Speech Language Pathology and Audiology Sciences were discarded. The data were analyzed descriptively and classified subareas of Speech Language Pathology and Audiology Sciences. The following items were considered: purposes, participants, procedures, and results. We selected 12 articles for ultrasound versus speech/phonetics subarea, 5 for ultrasound versus voice, 1 for ultrasound versus muscles of mastication, and 10 for ultrasound versus swallow. Studies relating "ultrasound" and "Speech Language Pathology and Audiology Sciences" in the past 5 years were not found. Different studies on the use of ultrasound in Speech Language Pathology and Audiology Sciences were found. Each of them, according to its purpose, confirms new possibilities of the use of this instrument in the several subareas, aiming at a more accurate diagnosis and new evaluative and therapeutic possibilities.

Audiology Assistants in Private Practice

PubMed Central

Hamill, Teri A.; Andrews, Julia P.

2016-01-01

Using audiology assistants allows a practice to meet the expected increase in patient demand in a cost-effective manner, without compromise to quality of patient care. Assistants are particularly valuable in private practice settings that have an emphasis in amplification, as many of the tasks involved do not require the unique skills of the doctor of audiology. Regulatory considerations, methods of training, and scope of practice of the assistant are discussed. PMID:28028327

The role of volunteer support in the community for adults with hearing loss and hearing aids.

To explore interactions between audiology patients and volunteers, to describe encounters and define the role of volunteers. Qualitative ethnographic and interview study of volunteer-patient interactions. Ten volunteer participants from two volunteer schemes in South West England were observed and interviewed. Three patient participants were interviewed. Analysis of observational data showed that volunteers provided support relating to local services and hearing aids, but did not engage in discussions about hearing loss. Interviews with volunteers identified gaps in audiology provision, including accessible services and clear information and highlighted a need for more support from audiology services to enable them to fulfil their role. Volunteer interactions with patients mimicked a clinician-patient encounter and volunteers employed strategies and behaviours used by professional audiologists. Audiology volunteers could provide an accessible bridge between health services and the community but their care is limited to focus on hearing aids. Volunteers enable patients to use hearing aids appropriately and are a core element of current care arrangements. However, volunteers express a need for adequate support from audiology services. Volunteers have the potential to increase service capacity and to bridge the gaps between community and audiology healthcare services. Copyright © 2015 The Authors.

Alanazi, Ahmad A

2017-01-01

Audiology and speech-language pathology (SLP) are relatively new professions in Saudi Arabia. The idea of establishing new audiology and SLP programs in some education facilities has become popular across Saudi Arabia; yet, only four undergraduate and graduate programs are currently available. This study aimed to explore the fields of audiology and SLP in Saudi Arabia, obtain demography of audiologists and Speech-language pathologists (SLPs), understand their current practices, and identify their perspective on what both professions need to improve. A cross-sectional mixed methods study design was used to address the aim of this study. Two online surveys were prepared and distributed to reach a large number of audiologists and SLPs. Both surveys consisted of close- and open-ended questions and primarily focused on three categories demography, audiology or SLP practices, and audiologists' or SLPs' perspective on their professions in Saudi Arabia. A total of 23 audiologists and 37 SLPs completed the surveys (age range = 21-50 years). The majority of respondents were from Riyadh with different academic qualifications and working experiences. Various practices were noticed among audiologists and SLPs who mainly worked in hospitals. Several suggestions regarding the development of audiology and SLP education and practice in Saudi Arabia are discussed. This study provides useful information about audiology and SLP education and practices in Saudi Arabia. Collaborative work between stakeholders to achieve high-quality educational and practical standards is critical. National database, clinical guidelines and policies should be developed, employed, and supervised. Further research is needed to improve education and practice of both professions in Saudi Arabia.

Optimizing otoscopy competency in audiology students through supplementary otoscopy training.

Scope of practice in audiology encompasses proficiency in visual inspection of ear canal and tympanic membrane (TM) as well as otoscopy interpretation skills to determine normal versus abnormal conditions of outer and middle ear. Audiology students can develop skills in otoscopy through education and supervised training. Studies have shown that additional otoscopy training increased skills in medical students and general practitioners. However, educational and supervised practices targeting otoscopy competency during audiology graduate coursework are lacking. Also, no studies have attempted to determine otoscopy skills among audiology students. To determine the effectiveness of the otoscopy training model on clinical competency and confidence level of audiology students in performing and interpreting otoscopy. A combination of experimental treatment design with random assignment of treatment and control groups and delayed treatment for control group. Thirty-two first- and second-year audiology graduate students who were enrolled in a pediatric audiology class participated in this study. Students were randomly assigned to the control (n = 16, 14 females) or experimental (n = 16, 14 females) group. Participants in the experimental group received supplementary otoscopy training including didactic otoscopy lectures as well as clinical training using manikin ears. The control group received the same pretest and posttest and then completed a third assessment (posttest 2) after receiving the same training. An evaluation of knowledge and skills regarding otoscopy between groups and time was conducted at three times: (a) pretraining, (b) upon completion of training for the experimental group, (c) upon completion of training by the control group. The evaluation consisted of a written exam, a clinical exam, and a self-perception rating of confidence. Both written exam scores and clinical exam scores (otoscopy manikin) were analyzed via two-way analyses of variance (ANOVAs), whereas chi-square (χ²) statistic was conducted to evaluate the effects of training on the confidence level of students of both groups. Experimental and control groups demonstrated significant increased overall competency in otoscopy following the otoscopy training model with didactic and laboratory components. Posttest confidence ratings showed increases in all groups, and there were no significant differences between groups. The need for supplementary otoscopy training was warranted by low knowledge and clinical competency in otoscopy skills of audiology students as measured by pretest mean scores. After completing the training, both experimental and control groups showed significant improvement in knowledge and competency. Results also suggest that perceived confidence ratings may be misleading in determining students' clinical otoscopy skills. American Academy of Audiology.

Allowing Medicare beneficiaries to self-refer to audiologists for evaluation of hearing loss has been advocated as a cost-effective service delivery model. Resistance to audiology direct access is based, in part, on the concern that audiologists might miss significant otologic conditions. To evaluate the relative safety of audiology direct access by comparing the treatment plans of audiologists and otolaryngologists in a large group of Medicare-eligible patients seeking hearing evaluation. Retrospective chart review study comparing assessment and treatment plans developed by audiologists and otolaryngologists. 1550 records comprising all Medicare eligible patients referred to the Audiology Section of the Mayo Clinic Florida in 2007 with a primary complaint of hearing impairment. Assessment and treatment plans were compiled from the electronic medical record and placed in a secured database. Records of patients seen jointly by audiology and otolaryngology practitioners (Group 1: 352 cases) were reviewed by four blinded reviewers, two otolaryngologists and two audiologists, who judged whether the audiologist treatment plan, if followed, would have missed conditions identified and addressed in the otolaryngologist's treatment plan. Records of patients seen by audiology but not otolaryngology (Group 2: 1198 cases) were evaluated by a neurotologist who judged whether the patient should have seen an otolaryngologist based on the audiologist's documentation and test results. Additionally, the audiologist and reviewing neurotologist judgments about hearing asymmetry were compared to two mathematical measures of hearing asymmetry (Charing Cross and AAO-HNS [American Academy of Otolaryngology-Head and Neck Surgery] calculations). In the analysis of Group 1 records, the jury of four judges found no audiology discrepant treatment plans in over 95% of cases. In no case where a judge identified a discrepancy in treatment plans did the audiologist plan risk missing conditions associated with significant mortality or morbidity that were subsequently identified by the otolaryngologist. In the analysis of Group 2 records, the neurotologist judged that audiology services alone were all that was required in 78% of cases. An additional 9% of cases were referred for subsequent medical evaluation. The majority of remaining patients had hearing asymmetries. Some were evaluated by otolaryngology for hearing asymmetry in the past with no interval changes, and others were consistent with noise exposure history. In 0.33% of cases, unexplained hearing asymmetry was potentially missed by the audiologist. Audiologists and the neurotologist demonstrated comparable accuracy in identifying Charing Cross and AAO-HNS pure-tone asymmetries. Of study patients evaluated for hearing problems in the one-year period of this study, the majority (95%) ultimately required audiological services, and in most of these cases, audiological services were the only hearing health-care services that were needed. Audiologist treatment plans did not differ substantially from otolaryngologist plans for the same condition; there was no convincing evidence that audiologists missed significant symptoms of otologic disease; and there was strong evidence that audiologists referred to otolaryngology when appropriate. These findings are consistent with the premise that audiology direct access would not pose a safety risk to Medicare beneficiaries complaining of hearing impairment. American Academy of Audiology.

Simulated patients in audiology education: student reports.

2013-09-01

Despite increased attention in recent years to audiology counseling education, students remain concerned about their abilities to interact with patients in challenging situations, such as when breaking difficult news. Simulated patients, or actors trained to portray patients in clinical scenarios, have been used for many years in medical schools to teach and assess students' interpersonal skills, and are just beginning to be used in audiology programs. Although research suggests that medical students value simulated patient experiences, little is known about whether the same is true for audiology students. The purpose of this study was to survey audiology students who had completed a simulated patient counseling experience as part of their graduate coursework at Central Michigan University, to learn about their experiences and views of this instructional format. This study used descriptive and comparative statistics to report student observations and to determine if student responses to evaluative questions differed from chance. Study participants included 29 audiology students who had completed a "breaking difficult news" simulated patient experience as part of their required graduate coursework in patient counseling. Participants completed an online survey that included seven evaluative five-point Likert-scale questions about their simulated patient counseling experience. Participants also completed one multiple-choice question on suggestions for future simulated-patient sessions. For each of the seven evaluative questions, a majority of participants (76-100%) responded positively, agreeing or strongly agreeing that the experience was helpful to their learning. For each of these evaluative questions, a χ² analysis revealed that the distribution of positive (i.e., strongly agree and agree) to nonpositive (i.e., neutral, disagree, and strongly disagree) responses differed significantly from chance (p < .0001, df = 1). The results also indicated that when asked which of several suggested clinical scenarios would be helpful for future sessions, simulations of challenging patient types (i.e., hostile, rambling, and noncommunicative patients) were supported by most (62-90%) respondents. The results of the present study are consistent with findings of medical students' positive perceptions of simulated patient experiences as well as those previously reported for audiology students. Together, these data support the continued use of simulated patients as a method of instruction for audiology counseling education for breaking difficult news, and suggest a potential value of using simulated patient interactions for training counseling skills in other clinical situations and scenarios.

Reports of audiological manifestations in specific subgroups of mitochondrial disorders are limited. This study aims to describe the audiological findings in patients with MELAS syndrome and m.3243A>G mutation. Audiological evaluation was carried out in eight patients with confirmed MELAS syndrome and m.3243A>G mutation. The evaluation included a complete neurological evaluation, pure tone audiometry (n=8), otoacoustic emissions (n=8) and brainstem evoked response audiometry (n=6), magnetic resonance imaging (n=8) and muscle biospy (n=6). Eight patients (Age range: 5-45 years; M:F-1:3) including six children and two adults underwent formal audiological evaluation. Five patients had hearing loss; of these two had "subclinical hearing loss", one had moderate and two had severe hearing loss. The abnormalities included abnormal audiometry (n=5), otoacoustic emission testing (n=7) and absent brainstem auditory evoked responses (n=1). The findings were suggestive of cochlear involvement in four and retrocochlear in one. This study shows that hearing loss of both cochlear and retrocochlear origin occurs in patients with MELAS and may be subclinical. Early referrals for audiological evaluation is warranted to recognize the subclinical hearing loss in these patients. The therapeutic implications include early interventions in the form of hearing aids, cochlear implants and cautioning the physicians for avoidance of aminoglycosides. Copyright © 2016 Elsevier B.V.

To apply Lean Sigma--a quality improvement strategy to eliminate waste and reduce variation and defects--to improve audiology scheduling and utilization in a large tertiary care referral center. The project goals included an increase in utilization rates of audiology block time and a reduction in appointment lead time. Prospective quality improvement study. Academic tertiary care center. All patients scheduling audiology clinic visits July 2013 to July 2014. Value stream mapping was performed for the audiology scheduling process, and wasteful steps were identified for elimination. Interventions included a 2-week block release, audiology template revision, and reduction of underutilized blocks. Schedule utilization and lead time for new patient diagnostic audiogram were measured for 5 months postintervention and compared with 5 months preintervention. Overall, 2995 preintervention and 3714 postintervention booked appointments were analyzed. Block utilization increased from 77% to 90% after intervention (P < .0001). Utilization of joint-with-provider visits increased from 39% to 67% (P < .0001). Booked appointments increased from 2995 to 3714, with joint-with-provider booked appointments increasing from 317 to 1193. Appointment lead time averaged 24 days postintervention, compared with 29 days preintervention (P = .06). Average monthly relative value units measured 13,321 preintervention and 14,778 postintervention (P = .09). Lean Sigma techniques were successfully used to increase appointment block utilization and streamline scheduling practices. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

No core list of periodicals exists for speech pathology and audiology. Faced with the prospect of having to cancer periodicals for all subjects, the science librarians at Illinois State University decided to determine which science periodicals were used most heavily. A one-year study of science periodical reshelving and interlibrary loan requests yielded ranked lists of periodicals important to speech pathology and audiology faculty and students at Illinois State University. The three most heavily used journals were the Journal of Speech and Hearing Research, ASHA, and Topics in Language Disorders. Most of the periodicals on the lists were indexed by either MEDLINE or UnCover, or by both. While the lists of journals developed in the study are not sufficient to serve as true core lists, they should be useful to libraries supporting comparable programs in speech pathology and audiology.

Audiologic features of Norrie disease.

PubMed

Halpin, Chris; Owen, Grace; Gutiérrez-Espeleta, Gustavo A; Sims, Katherine; Rehm, Heidi L

2005-07-01

Norrie disease is an X-linked recessive disorder in which patients are born blind and develop sensory hearing loss in adolescence. The hearing loss associated with Norrie disease has been shown in a genetically altered knockout mouse to involve dysfunction of the stria vascularis; most other structures are preserved until the later stages of the disease. The objective of this study was to characterize the audiologic phenotype of Norrie disease for comparison with the pathophysiologic mechanism. The design combined two series of clinical audiologic evaluations, with special attention to speech intelligibility. The audiologic results for 12 affected individuals and 10 carriers show that patients with Norrie disease retain high speech intelligibility scores even when the threshold loss is severe. The cochlear mechanism-- failure of the stria vascularis-- accounts for some of the higher values in the wide distribution of speech scores in cases with similar pure tone audiograms.

A significant portion of the AuD curriculum occurs in clinical settings outside the classroom. Expert clinicians, employed within and outside of the university, are called upon to provide this clinical education. Most have had little or no formal training in clinical teaching yet face pedagogical and logistical challenges when simultaneously providing clinical service and teaching. Training to provide optimal methods and approaches to clinical instruction should be based on research evidence; however, there is a paucity of research in this area within the audiology discipline. This article provides a review of literature supplying evidence for important concepts, elements, and approaches to the clinical instruction process. Additionally, we provide readers with some practical tools with which to facilitate application of optimal clinical teaching principles. We conducted a systematic review of literature on clinical education in audiology and across a wide array of health professions. Through the use of content analysis we identified four elements of the clinical teaching process most critical in examining optimal practices. The elements identified as critical to positive clinical learning outcomes include the establishment of mutual expectations and goals; structured content and delivery of feedback; establishment of a positive instructor/student relationship; and questioning strategies that lead to the development of critical thinking skills. Many disciplines outside of audiology demonstrate robust research activity related to understanding and optimizing the clinical education process. The application of a number of evidence-based clinical teaching principles should allow us to improve student outcomes in audiology. Researchers in our field might consider if and how we should develop our own research literature in clinical education. American Academy of Audiology.

Interventional audiology, specifically community-based outreach, can connect people with the hearing health care system. Community-based participatory research methods were applied in two phases of research to: (1) investigate the needs of families affected by hearing loss in a rural Arizona community on the U.S.–Mexico border; and (2) evaluate an outreach program on hearing health. The needs assessment included interviews with persons with hearing loss and focus groups with family members and the greater community. The needs assessment revealed that despite perceived severity of hearing loss, help-seeking for audiologic care was limited due to barriers, stigma, and low self-efficacy. Results informed development of a community-based pilot study conducted as part of an academic-community partnership between audiology, public health, and community health workers of a federally qualified health center. An outreach program, Oyendo Bien (hearing wellness), a 5-week, Spanish-language health education program for older adults (n = 21) incorporated communication strategies and behavioral change techniques. Postprogram focus groups revealed increased self-efficacy and decreased stigma. After 1 year, 7 of 9 participants with hearing loss contacted for follow-up had sought some form of hearing-related health care. Future research should further investigate interventional audiology approaches to address health disparities. PMID:28522894

Knowledge Translation in Audiology

Kothari, Anita; Bagatto, Marlene P.; Seewald, Richard; Miller, Linda T.; Scollie, Susan D.

2011-01-01

The impetus for evidence-based practice (EBP) has grown out of widespread concern with the quality, effectiveness (including cost-effectiveness), and efficiency of medical care received by the public. Although initially focused on medicine, EBP principles have been adopted by many of the health care professions and are often represented in practice through the development and use of clinical practice guidelines (CPGs). Audiology has been working on incorporating EBP principles into its mandate for professional practice since the mid-1990s. Despite widespread efforts to implement EBP and guidelines into audiology practice, gaps still exist between the best evidence based on research and what is being done in clinical practice. A collaborative dynamic and iterative integrated knowledge translation (KT) framework rather than a researcher-driven hierarchical approach to EBP and the development of CPGs has been shown to reduce the knowledge-to-clinical action gaps. This article provides a brief overview of EBP and CPGs, including a discussion of the barriers to implementing CPGs into clinical practice. It then offers a discussion of how an integrated KT process combined with a community of practice (CoP) might facilitate the development and dissemination of evidence for clinical audiology practice. Finally, a project that uses the knowledge-to-action (KTA) framework for the development of outcome measures in pediatric audiology is introduced. PMID:22194314

Abstract Introduction: Millions of global citizens suffering from hearing disorders have limited or no access to much needed hearing healthcare. Although tele-audiology presents a solution to alleviate this problem, existing remote hearing diagnosis systems support only pure-tone tests, leaving speech and other test procedures unsolved, due to the lack of software and hardware to enable communication required between audiologists and their remote patients. This article presents a comprehensive remote hearing test system that integrates the two most needed hearing test procedures: a pure-tone audiogram and a speech test. Materials and Methods: This enhanced system is composed of a Web application server, an embedded smart Internet-Bluetooth® (Bluetooth SIG, Kirkland, WA) gateway (or console device), and a Bluetooth-enabled audiometer. Several graphical user interfaces and a relational database are hosted on the application server. The console device has been designed to support the tests and auxiliary communication between the local site and the remote site. Results: The study was conducted at an audiology laboratory. Pure-tone audiogram and speech test results from volunteers tested with this tele-audiology system are comparable with results from the traditional face-to-face approach. Conclusions: This browser-server–based comprehensive tele-audiology offers a flexible platform to expand hearing services to traditionally underserved groups. PMID:25919376

Iliadou, Vasiliki Vivian; Chermak, Gail D; Bamiou, Doris-Eva

2015-04-01

According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, diagnosis of speech sound disorder (SSD) requires a determination that it is not the result of other congenital or acquired conditions, including hearing loss or neurological conditions that may present with similar symptomatology. To examine peripheral and central auditory function for the purpose of determining whether a peripheral or central auditory disorder was an underlying factor or contributed to the child's SSD. Central auditory processing disorder clinic pediatric case reports. Three clinical cases are reviewed of children with diagnosed SSD who were referred for audiological evaluation by their speech-language pathologists as a result of slower than expected progress in therapy. Audiological testing revealed auditory deficits involving peripheral auditory function or the central auditory nervous system. These cases demonstrate the importance of increasing awareness among professionals of the need to fully evaluate the auditory system to identify auditory deficits that could contribute to a patient's speech sound (phonological) disorder. Audiological assessment in cases of suspected SSD should not be limited to pure-tone audiometry given its limitations in revealing the full range of peripheral and central auditory deficits, deficits which can compromise treatment of SSD.

To study the quality of life (QoL) and psychosocial consequences in terms of sick leave and audiological rehabilitation given to patients with severe to profound hearing impairment. A retrospective study of data on 2319 patients with severe to profound hearing impairment in The Swedish Quality Register of Otorhinolaryngology, followed by a posted questionnaire including The Hospital Anxiety and Depression Scale (HADS). The results indicate greater levels of anxiety and depression among patients with severe or profound hearing impairment than in the general population, and annoying tinnitus and vertigo had strong negative effects on QoL. The proportion of sick leave differed between the studied dimensions in the study. The proportion of patients who received extended audiological rehabilitation was 38% in the present study. Treatment focused on anxiety, depression, tinnitus and vertigo must be given early in the rehabilitation process in patients with severe or profound hearing impairment. Because sick leave differs greatly within this group of patients, collaboration with the regional Social Insurance Agency is crucial part of the rehabilitation. The study also shows that presently, only a small proportion of patients in Sweden with severe to profound hearing impairment receive extended audiological rehabilitation. Implications for Rehabilitation Greater levels of anxiety and depression have been found among patients with severe or profound hearing impairment than in the general population, and annoying tinnitus and vertigo have strong negative effects on QoL in this group of patients. Only a small proportion of patients with severe to profound hearing impairment receive extended audiological rehabilitation today, including medical, technical and psychosocial efforts. Extended audiological rehabilitation focused on anxiety, depression, tinnitus and vertigo must be given, together with technical rehabilitation, early in the rehabilitation process in patients with severe or profound hearing impairment.

Noise-induced hearing loss (NIHL) from prolonged occupational exposure to noise continues to rank among the top worldwide work-related ill-health problems. To provide an overview of incident cases based on work-related audiological ill-health data collected over a 9-year period from occupational physicians (OPs), audiological physicians (APs), general practitioners and otorhinolaryngologists. Analysis of numerator data reported by physicians to surveillance schemes within The Health and Occupation Reporting network (THOR). The actual cases were multiplied by the sampling ratio to provide estimated numerator numbers, followed by calculation of incidence rates using denominator data derived from the Labour Force Survey and from surveys of participating OPs. Two thousand five hundred and eighty-two estimated cases (2584 estimated diagnoses) were received from OPs (Occupational Physicians Reporting Activity [OPRA]), and 2192 estimated cases (3208 estimated diagnoses) of work-related audiological ill-health were received from consultant APs [Occupational Surveillance Scheme for Audiological physicians (OSSA)] from 1998 to 2006. Cases where the causal agent was noise exposure (NIHL and tinnitus) made up of 95 and 97% of all cases reported to OPRA and OSSA, respectively. The annual average incidence rate for noise-induced audiological disorders was 7.9 [95% confidence interval (CI) 4.6-11.1] per 100 000 persons employed (OPRA) and 0.8 (95% CI 0.7-1.0) per 100 000 persons employed (OSSA). Workers with the highest incidence were older males employed in public administration and defence and the manufacture of metals. THOR data show that diagnoses related to work-related noise exposure (NIHL/tinnitus), as reported to THOR, remain important health problems, despite preventive measures being in place.

Theses are the prime indicators of the scientific productivity of a country and one of the main and strongest resources for the emergence of scientific articles. This study aims to examine, by using the survey method, how many of the audiology master and/or doctoral theses in Turkey were turned into a scientific work. Individuals who received a master's degree in audiology were surveyed whether their theses had been reviewed as a paper or publication. Forty-five of the 230 audiology specialists and 22 audiologists with a doctorate degree working in Turkey participated in the study by answering the survey questions. In general, while 45.4% of master theses were presented orally or as a poster presentation in a national convention, 20.4% were presented orally or as a poster presentation in an international convention. While 18.1% of theses were published as an article in a national journal, 15.9% were published as an article in an international SCI or SCI-E journal. The distribution of the doctoral theses is 26.6%, 33.3%, 13.3% and 26.6%, respectively. We found the rate of theses in audiology turning into a scientific article to be below the desired level, as in other fields. The reasons for this should be emphasized and efforts should be made to raise these rates to the desired level.

To develop a tool for assessing audiology students taking a case history and giving feedback with simulated patients (SP). Single observation, single group design. Twenty-four first-year audiology students, five simulated patients, two clinical educators, and three evaluators. The Audiology Simulated Patient Interview Rating Scale (ASPIRS) was developed consisting of six items assessing specific clinical skills, non-verbal communication, verbal communication, interpersonal skills, interviewing skills, and professional practice skills. These items are applied once for taking a case history and again for giving feedback. The ASPIRS showed very high internal consistency (α = 0.91-0.97; mean inter-item r = 0.64-0.85) and fair-to-moderate agreement between evaluators (29.2-54.2% exact and 79.2-100% near agreement; κ weighted up to 0.60). It also showed fair-to-moderate absolute agreement amongst evaluators for single evaluator scores (intraclass correlation coefficient [ICC] r = 0.35-0.59) and substantial consistency of agreement amongst evaluators for three-evaluator averaged scores (ICC r = 0.62-0.81). Factor analysis showed the ASPIRS' 12 items fell into two components, one containing all feedback items and one containing all case history items. The ASPIRS shows promise as the first published tool for assessing audiology students taking a case history and giving feedback with an SP.

Ira Hirsh's contributions to clinical science and research are diverse and significant. In fact, approximately one-third of the 100+ publications that Ira lists in his curriculum vitae (CV) are clinical in nature, dealing with various aspects of audiology, deafness, hearing aids, aural rehabilitation, and speech and language pathology. The majority of these citations, fully one-quarter of his publication list, addresses problems specific to the clinical measurement of hearing and hearing impairment. Undoubtedly, the most influential of these published works appears in his CV under the citation ``The Measurement of Hearing.'' The forward for this publication, his only textbook, was penned in June, 1952 (now precisely half a century past at the time of this session). The aims of this presentation are to (1) provide perspective on the fundamental importance of his virtually timeless text in shaping the fledgling discipline of audiology, and (2) celebrate Ira's many contributions to the profession and practice of audiology.

2012-01-01

This study aimed to investigate occupational stress amongst audiologists, along with quantification of their professional quality of life: Burnout, compassion fatigue, and compassion satisfaction. A cross-sectional postal survey research design using an audiology occupational stress questionnaire (AOSQ), and the professional quality of life (ProQOL) instrument. The sample consisted of members of the New Zealand Audiological Society. One hundred and forty-five questionnaires were mailed, 82 responses were received. The main findings suggest that six stress factors dominate clinical audiology: (1) time demand, (2) audiological management, (3) patient contact, (4) clinical protocol, (5) patient accountability, and (6) administration or equipment. A significant relationship was found between increasing age of the audiologist and risk of acquiring burnout (chi-square (1)=6.119, p<0.05). Pearson's correlation's revealed time demand was the strongest predictor of low compassion satisfaction (r=0.327) and burnout (r=0.463), while stress associated with patient contact was the strongest predictor of compassion fatigue (r=0.352). This study identifies sources of stress for clinical audiologists and different factors that contribute to professional quality of life.

Subjective tinnitus, or ringing sensation in the ear, is a common disorder with no accepted objective diagnostic markers. The purpose of this study was to identify possible objective markers of tinnitus by combining audiological and imaging-based techniques. Case-control studies. Twenty adults drawn from our audiology clinic served as participants. The tinnitus group consisted of ten participants with chronic bilateral constant tinnitus, and the control group consisted of ten participants with no history of tinnitus. Each participant with tinnitus was closely matched with a control participant on the basis of age, gender, and hearing thresholds. Data acquisition focused on systematic administration and evaluation of various audiological tests, including auditory-evoked potentials (AEP) and otoacoustic emissions, and magnetic resonance imaging (MRI) tests. A total of 14 objective test measures (predictors) obtained from audiological and MRI tests were subjected to statistical analyses to identify the best predictors of tinnitus group membership. The least absolute shrinkage and selection operator technique for feature extraction, supplemented by the leave-one-out cross-validation technique, were used to extract the best predictors. This approach provided a conservative model that was highly regularized with its error within 1 standard error of the minimum. The model selected increased frontal cortex (FC) functional MRI activity to pure tones matching their respective tinnitus pitch, and augmented AEP wave N₁ amplitude growth in the tinnitus group as the top two predictors of tinnitus group membership. These findings suggest that the amplified responses to acoustic signals and hyperactivity in attention regions of the brain may be a result of overattention among individuals that experience chronic tinnitus. These results suggest that increased functional MRI activity in the FC to sounds and augmented N₁ amplitude growth may potentially be the objective diagnostic indicators of tinnitus. However, due to the small sample size and lack of subgroups within the tinnitus population in this study, more research is needed before generalizing these findings. American Academy of Audiology

SUMMARY In the context of permanent childhood hearing loss, early audiological diagnosis is a prerequisite for activation of an adequate rehabilitation program to prevent or limit the known effects that auditory deprivation determines on language development and cognitive skills in neonates. Audiological diagnosis consists schematically of three phases: identification of subjects at risk, definition of hearing loss and/or children features, verification of appropriateness of diagnosis itself and a rehabilitation programme. Strategies and methods of audiological diagnosis are well defined and include an integration of data coming from objective methods with clinical and behavioural data. Although the substantial effectiveness of procedures and a general consensus on their use and interpretation have been defined, there are several critical issues concerning the achievement of this objective, which will be discussed in this paper.

Existing literature only reports a few patients with Noonan syndrome (NS) and Noonan syndrome with multiple lentigines (NSML) who underwent cochlear implantation (CI). The present study describes four NS patients and one NSML patient with a PTPN11 mutation. They all had severe to profound hearing loss, and they received a CI. The age at which the CI surgery occurred ranged from 1 to 13 years old, and the audiological results in all five patients improved after the CI. Otological and audiological examinations in NS and NSML are important, and for those with severe hearing loss, the CI surgery improved the audiological outcome regardless of age.

Criter, Robin E; Honaker, Julie A

2017-10-01

The primary purposes of this study were (1) to describe measures that may contrast audiology patients who fall from those who do not fall and (2) to evaluate the clinical performance of measures that could be easily used for fall risk screening in a mainstream audiology hearing clinic. Cross-sectional study Study sample: Thirty-six community-dwelling audiology patient participants and 27 community-dwelling non-audiology patients over 60 years of age. The Hearing Handicap Inventory for the Elderly (HHIE) most accurately identified patients with a recent fall (sensitivity: 76.0%), while the Dizziness Handicap Inventory (DHI) most accurately identified patients without a recent fall (specificity: 90.9%). A combination of measures used in a protocol-including HHIE, DHI, number of medications, and the Timed Up and Go test-resulted in good, accurate identification of patients with or without a recent history of falls (92.0% sensitivity, 100% specificity). This study reports good sensitivity and excellent specificity for identifying patients with and without a recent history of falls when measures were combined into a screening protocol. Despite previously reported barriers, effective fall risk screenings may be performed in hearing clinic settings with measures often readily accessible to audiologists.

Although current guidelines recommend cochlear implantation only for children with profound hearing impairment (HI) (>90 decibel [dB] hearing level [HL]), studies show that children with severe hearing impairment (>70-90 dB HL) could also benefit from cochlear implantation. To perform a systematic review to identify audiologic thresholds (in dB HL) that could serve as an audiologic candidacy criterion for pediatric cochlear implantation using 4 domains of speech and language development as independent outcome measures (speech production, speech perception, receptive language, and auditory performance). PubMed and Embase databases were searched up to June 28, 2017, to identify studies comparing speech and language development between children who were profoundly deaf using cochlear implants and children with severe hearing loss using hearing aids, because no studies are available directly comparing children with severe HI in both groups. If cochlear implant users with profound HI score better on speech and language tests than those with severe HI who use hearing aids, this outcome could support adjusting cochlear implantation candidacy criteria to lower audiologic thresholds. Literature search, screening, and article selection were performed using a predefined strategy. Article screening was executed independently by 4 authors in 2 pairs; consensus on article inclusion was reached by discussion between these 4 authors. This study is reported according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. Title and abstract screening of 2822 articles resulted in selection of 130 articles for full-text review. Twenty-one studies were selected for critical appraisal, resulting in selection of 10 articles for data extraction. Two studies formulated audiologic thresholds (in dB HLs) at which children could qualify for cochlear implantation: (1) at 4-frequency pure-tone average (PTA) thresholds of 80 dB HL or greater based on speech perception and auditory performance subtests and (2) at PTA thresholds of 88 and 96 dB HL based on a speech perception subtest. In 8 of the 18 outcome measures, children with profound HI using cochlear implants performed similarly to children with severe HI using hearing aids. Better performance of cochlear implant users was shown with a picture-naming test and a speech perception in noise test. Owing to large heterogeneity in study population and selected tests, it was not possible to conduct a meta-analysis. Studies indicate that lower audiologic thresholds (≥80 dB HL) than are advised in current national and manufacturer guidelines would be appropriate as audiologic candidacy criteria for pediatric cochlear implantation.

Standardized patients in audiology: a proposal for a new method of evaluating clinical competence.

Dinsmore, Brooke Freeman; Bohnert, Carrie; Preminger, Jill E

2013-05-01

While accrediting organizations require AuD programs to provide evidence that their students are able to demonstrate knowledge and competencies in specific content areas, there are no generally accepted mechanisms for the assessment and the measurement of these proficiencies. We propose that AuD programs consider developing standardized patient (SP) cases in order to develop consistent summative assessment programs within and across universities. The purpose of this article is to provide a framework for establishing SP programs to evaluate competencies in AuD students by detailing the history of SP cases and their use, developing a rationale for this method of assessment, and outlining the steps for writing and implementing SP cases. Literature review. SPs have been used to assess clinical competence in medical students for over 50 yr. The prevalence of SP assessment in allied health professions (e.g., dentistry, psychology, pharmacy) has increased over the last two decades but has only gained a limited following in audiology. SP assessment has been implemented in medical education using the Objective Structured Clinical Examination, a multistation, timed exam that uses fictional cases to assess students' clinical abilities. To date, only one published report has been completed that evaluates the use of SPs to assess clinical abilities in audiology students. This article expands upon the work of English et al (2007) and their efforts to use SPs to evaluate counseling abilities. To this end, we describe the steps necessary to write a case, procedures to determine performance requirements, and the need to develop remediation plans. As an example, we include a case that we have developed in order to evaluate vestibular assessment and patient communication skills. Utilizing SP assessment in audiology education would provide useful means to evaluate competence in a uniform way. Future research is necessary to develop reliable and valid cases that may be implemented across programs. This article aims to serve as a call to audiology programs to begin developing and reporting these cases. Once these are established we can begin to use SP cases for summative assessment.

Effects of Age on Auditory and Cognitive Processing: Implications for Hearing Aid Fitting and Audiologic Rehabilitation

PubMed Central

Pichora-Fuller, M. Kathleen; Singh, Gurjit

2006-01-01

Recent advances in research and clinical practice concerning aging and auditory communication have been driven by questions about age-related differences in peripheral hearing, central auditory processing, and cognitive processing. A “site-of-lesion” view based on anatomic levels inspired research to test competing hypotheses about the contributions of changes at these three levels of the nervous system. A “processing” view based on psychologic functions inspired research to test alternative hypotheses about how lower-level sensory processes and higher-level cognitive processes interact. In the present paper, we suggest that these two views can begin to be unified following the example set by the cognitive neuroscience of aging. The early pioneers of audiology anticipated such a unified view, but today, advances in science and technology make it both possible and necessary. Specifically, we argue that a synthesis of new knowledge concerning the functional neuroscience of auditory cognition is necessary to inform the design and fitting of digital signal processing in “intelligent” hearing devices, as well as to inform best practices for resituating hearing aid fitting in a broader context of audiologic rehabilitation. Long-standing approaches to rehabilitative audiology should be revitalized to emphasize the important role that training and therapy play in promoting compensatory brain reorganization as older adults acclimatize to new technologies. The purpose of the present paper is to provide an integrated framework for understanding how auditory and cognitive processing interact when older adults listen, comprehend, and communicate in realistic situations, to review relevant models and findings, and to suggest how new knowledge about age-related changes in audition and cognition may influence future developments in hearing aid fitting and audiologic rehabilitation.

2017-01-01

Purpose The purpose of this study was to examine the readability level of the Spanish versions of several audiology- and otolaryngology-related patient-reported outcome measures (PROMs) and include a readability analysis of 2 translation approaches when available—the published version and a “functionalist” version—using a team-based collaborative approach including community members. Method Readability levels were calculated using the Fry Graph adapted for Spanish, as well as the Fernandez-Huerta and the Spaulding formulae for several commonly used audiology- and otolaryngology-related PROMs. Results Readability calculations agreed with previous studies analyzing audiology-related PROMs in English and demonstrated many Spanish-language PROMs were beyond the 5th grade reading level suggested for health-related materials written for the average population. In addition, the functionalist versions of the PROMs yielded lower grade-level (improved) readability levels than the published versions. Conclusion Our results suggest many of the Spanish-language PROMs evaluated here are beyond the recommended readability levels and may be influenced by the approach to translation. Moreover, improved readability may be possible using a functionalist approach to translation. Future analysis of the suitability of outcome measures and the quality of their translations should move beyond readability and include an evaluation of the individual's comprehension of the written text.

2015-01-01

Background In future, the South African Department of Health aims to purchase services from accredited private service providers. Successful private audiology practices can assist to address issues of access, equity and quality of health services. It is not sufficient to be an excellent clinician, since audiology practices are businesses that must also be managed effectively. Objective The objective was to determine the existing and required levels of practice management knowledge as perceived by South African audiologists. Method An electronic descriptive survey was used to investigate audiology practice management amongst South African audiologists. A total of 147 respondents completed the survey. Results were analysed by calculating descriptive statistics. The Z-proportional test was used to identify significant differences between existing and required levels of practice management knowledge. Results Significant differences were found between existing and required levels of knowledge regarding all eight practice management tasks, particularly legal and ethical issues and marketing and accounting. There were small differences in the knowledge required for practice management tasks amongst respondents working in public and private settings. Conclusion Irrespective of their work context, respondents showed that they need significant expansion of practice management knowledge in order to be successful, to compete effectively and to make sense of a complex marketplace.

The focus of this study was to evaluate the prevalence, type, and severity of hearing impairment in patients with Duane's Retraction Syndrome and to relate these measures to patient demographics and other otologic and audiologic factors. Retrospective AudGen Database analysis Tertiary academic referral center Pediatric patients in AudGenDB with a diagnosis of Duane's Retraction Syndrome (DRS). Appropriate audiologic, otologic, and demographic data were recorded. Seventy-nine patients (n = 79) met inclusion criteria. The first encounter with available audiometric data or the first encounter with hearing loss were documented. Audiograms were stratified by type and severity of hearing loss, and common associated medical issues were documented. 57 children had normal hearing; 22 had hearing loss. 9 ears had pure conductive hearing loss, 1 had pure sensorineural, 14 ears had components of both, and 79 had hearing loss that could not be specified. Multivariate regression revealed episodes of chronic otitis and craniofacial anomalies are associated with worse hearing loss. This study presents a detailed characterization of hearing loss in patients with Duane's retraction syndrome. Conductive and sensorineural hearing loss are both prevalent among these children. Careful and early audiologic evaluation of all patients with DRS is important. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Health care professionals are expected to uphold high ethical standards. Recently, ethical practices in health care have received increased scrutiny and study in an effort to ensure that clinicians meet such high ethical standards in serving their patients and clients. The American Academy of Audiology's Code of Ethics establishes professional standards that allow for the proper discharge of an audiologist's responsibilities while maintaining the integrity of the profession. Under this code, student academy members are included and required to abide by the code, the same as practicing members. The code is composed of a preamble and eight principles. The present study provides an overview of students' perceptions across a broad spectrum of ethical topics governing our profession. Specifically, this study examined audiology students' perceptions of preceptor ethics relating to these eight principles using an online survey. Responses were collected from 143 of 600 audiology students contacted and indicated that they believed that their preceptors consistently followed each of the eight principles. Results also indicated that students believe fellow students also behave ethically and that it is the primary responsibility of academic faculty, not preceptors, to teach ethics. It can be concluded that preceptors are perceived by their students to be acting with high ethical standards. However, more research and discussion may be needed to determine who should teach these ethics to students.

Efforts to provide audiologic services to the Inuit population of the Baffin Zone have frequently resulted in unexpected problems and frustrations. Often these are the product of two very different cultures coming together. This paper reviews the author's personal experiences in this regard with special reference to hearing aid attitudes, noise exposure, and the making of instructional audio-visual materials. A brief description of a recently revised hearing conservation program at Frobisher Bay is provided.

This article aims to warn the Brazilian Speech-Language Pathology and Audiology scientific community about the importance and necessity of scientific and clinical activities regarding Primary Progressive Aphasia. This warning is based on a systematic literature review of the scientific production on Primary Progressive Aphasia, from which nine Brazilian articles were selected. It was observed that there is an obvious lack of studies on the subject, as all the retrieved articles were published in medical journals and much of it consisted of small samples; only two articles described the effectiveness of speech-language therapy in patients with Primary Progressive Aphasia. A perspective for the future in the area and characteristics of Speech-Language Therapy for Primary Progressive Aphasia are discussed. As a conclusion, it is evident the need for greater action by Speech-Language Pathology and Audiology on Primary Progressive Aphasia.

In the context of permanent childhood hearing loss, early audiological diagnosis is a prerequisite for activation of an adequate rehabilitation program to prevent or limit the known effects that auditory deprivation determines on language development and cognitive skills in neonates. Audiological diagnosis consists schematically of three phases: identification of subjects at risk, definition of hearing loss and/or children features, verification of appropriateness of diagnosis itself and a rehabilitation programme. Strategies and methods of audiological diagnosis are well defined and include an integration of data coming from objective methods with clinical and behavioural data. Although the substantial effectiveness of procedures and a general consensus on their use and interpretation have been defined, there are several critical issues concerning the achievement of this objective, which will be discussed in this paper. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale.

Diagnostic hearing testing of infants aged 0-36 months in 3 South African provinces - Comparison of audiology records to HPCSA guidelines.

2016-12-01

Within the Early Hearing Detection and Intervention (EHDI) pathway, which includes the processes of screening, diagnosis and intervention for paediatric hearing loss, paediatric diagnostic audiology involves a battery of specific tests and procedures. International studies have highlighted a golden standard for diagnosis of paediatric hearing loss as based on the Joint Committee of Infant Hearing (2007) diagnostic guidelines, closely resembling the HPCSA diagnostic guidelines. There are limited South African studies on the processes and protocols followed in diagnostic paediatric audiology. This study aims to provide a comparison for how the tests used for diagnosis of paediatric hearing loss in South Africa (within both the public and private healthcare sectors) compare to the HPCSA recommended diagnostic guidelines. A retrospective record review of paediatric clients with hearing loss (recruited through nonprobability convenience sampling) was conducted. This study is part of a longitudinal study of 711 deaf or hard of hearing children referred to the HI HOPES early intervention programme from September 2006 to December 2011. Diagnostic data from audiology reports of 117 children between 0 and 36 months were coded and analysed. Large variation was found in the tests included in the diagnostic audiology reports. For 22 children (19%) a comprehensive test battery was used. Health Professions Council of South Africa (HPCSA) recommended guidelines for diagnostic testing were not followed in any of the records analysed. Components of the HPCSA recommended test battery most frequently omitted was bone conduction testing. For both electrophysiology and behavioural testing, there was limited frequency specificity information. This exclusion of information is evidence of deficiencies in data recording and management, as well as having an effect on accuracy of classification of degree and type of hearing loss. There are gaps in age-appropriate assessment protocols, which will have an effect on accurate differential diagnosis of paediatric hearing loss. Reasons for not including all testing components of the HPCSA recommended guidelines, as well as the possibility of developing guidelines more relevant to a developing world context, should be explored. There might be a need for. The impact of South African specific factors that have an effect on provision of accurate paediatric diagnostic audiology services should be determined.

Many documents describe standardized methods and standard equipment requirements in the field of audiology and hearing aids. These standards will ensure a uniform level and a high quality of both the methods and equipment used in audiological work. The standards create the basis for measuring performance in a reproducible manner and independent from how and when and by whom parameters have been measured. This article explains, and focuses on, relevant acoustic and electromagnetic compatibility parameters and describes several test systems available. PMID:27516709

Audiologic correlates of hearing handicap in the elderly.

Weinstein, B E; Ventry, I M

1983-03-01

This investigation was conducted to determine the relationship between self-assessed hearing handicap and audiometric measures in a large sample of noninstitutionalized elderly individuals. Eighty subjects underwent a complete audiological evaluation and responded to the Hearing Measurement Scale (HMS). Each of the correlations between measures of sensitivity and the HMS score was statistically significant. The speech discrimination scores showed a somewhat lower correlation with the HMS score than did pure-tone measures. The implications of the above findings are discussed.

Audiology in Latin America: hearing impairment, resources and services.

Madriz, J J

2001-01-01

Evidence is presented about the limitation of information available on prevalence/incidence of deafness and hearing impairment in the developing world; particularly in Latin America. Two questionnaires on audiological resources and services were mailed to Latin American and Caribbean countries in general and to Central American nations in particular. The information returned by Argentina, Chile, Colombia, Costa Rica, Cuba, Belize, El Salvador, Grenada, Guatemala, Honduras, Mexico, Nicaragua, Panama, Puerto Rico and Uruguay was analysed. Data was gathered about epidemiological studies on hearing impairment, about specific programmes, such as early identification of hearing impairment, national registers on deafness and programmes on hearing screening. Training programmes and availability of professionals in the field of hearing and deafness is also shown. Hearing services, hearing aids provision, hearing testing equipment, professional organization and legislation in audiology is also documented. It is our conclusion that hearing impairment is a low priority for health systems in the developing world, technology continues to be excessively costly and material and human resources are limited, and services are poor and restricted.

What Is the International Classification of Functioning, Disability and Health and Why Is It Relevant to Audiology?

PubMed Central

Meyer, Carly; Grenness, Caitlin; Scarinci, Nerina; Hickson, Louise

2016-01-01

The World Health Organization's International Classification of Functioning, Disability and Health (ICF) is widely used in disability and health sectors as a framework to describe the far-reaching effects of a range of health conditions on individuals. This biopsychosocial framework can be used to describe the experience of an individual in the components of body functions, body structures, and activities and participation, and it considers the influence of contextual factors (environmental and personal) on these components. Application of the ICF in audiology allows the use of a common language between health care professionals in both clinical and research settings. Furthermore, the ICF is promoted as a means of facilitating patient-centered care. In this article, the relevance and application of the ICF to audiology is described, along with clinical examples of its application in the assessment and management of children and adults with hearing loss. Importantly, the skills necessary for clinicians to apply the ICF effectively are discussed. PMID:27489397

We first aimed to describe demographic and audiological characteristics of adults referred to a university hospital for hearing aid (HA) fitting and rehabilitation. Our second aim was to employ an inventory that assesses life consequences of hearing impairment (HI) in terms of perceived activity limitation and participation restriction for the first time in a Norwegian adult outpatient population. A third aim was to study life consequences by audiological and demographic characteristics. During one year consecutive patients (n = 343) were requested to answer the Hearing Disability and Handicap Scale (HDHS) assessing activity limitation and participation restriction in relation to an audiological examination and medical consultation. The mean threshold of hearing (MTH) was ascertained by pure tone thresholds at 0.5 - 1 - 2 - 4 kHz in the better ear. Activity limitation and participation restriction were both higher for HA experienced than HA naïve subjects ( p < 0.01). In a multivariable model, the explained adjusted variance of activity limitation (R2) was 43.4% with MTH, perceived duration, and severity of hearing problems as predictor variables. Correspondingly, the explained adjusted variance of participation restriction was 28.4% for a model with MTH, age, gender and perceived severity of hearing problems as predictors. As a standard supplement to audiometric tests, HDHS may be successfully applied as a clinical tool among similar hearing impaired outpatients in order to assess activity limitation and participation restriction as part of audiological rehabilitation.

Autism and peripheral hearing loss: a systematic review.

2014-01-01

To systematically review the literature describing the relationship between autism spectrum disorder (ASD) and peripheral hearing loss including literature recommendations for audiological assessment and auditory habilitation in cases where peripheral hearing loss and ASD coexist. Published studies indexed in MEDLINE (1948-2011). The search strategy identified 595 potential studies. After a review of the titles, 115 abstracts were reviewed and 39 articles were retrieved and assessed independently by at least two authors for possible inclusion. 22 articles pertained to children with ASD and peripheral hearing loss, hearing assessment in children with ASD, audiological habilitation for children with ASD or hyper-responsiveness in children with ASD. 17 further studies were garnered from the reference section of the 22 papers. Controversy exists in the literature regarding prevalence of hearing impairment among individuals with ASD. In cases where ASD and hearing impairment co-exist, diagnosis of one condition often leads to a delay in diagnosing the other. Audiological assessment can be difficult in children with ASD and test-retest reliability of behavioural thresholds can be poor. In cases where hearing impairment exists and hearing aids or cochlear implantation are recommended, devices are often fit with special considerations for the child with ASD. Hyper-responsiveness to auditory stimuli may be displayed by individuals with ASD. Evidence or the suspicion of hyper-responsiveness may be taken into consideration when fitting amplification and planning behavioural intervention. Prevalence rates of hearing impairment among individuals with ASD continue to be debated. At present there is no conclusive evidence that children with ASD are at increased risk of peripheral hearing loss. A complete audiological assessment is recommended in all cases where ASD is suspected so as not to delay the diagnosis of hearing impairment in the event that hearing loss and ASD co-exist. Objective assessment measures should be used to confirm behavioural testing in order to ensure reliability of audiological test results. Fitting of hearing aids or cochlear implantation are not contraindicated when hearing loss is present in children with ASD; however, success with these devices can be variable.

There is broad consensus that screening and diagnosis of permanent hearing loss in children must be embedded within a comprehensive, evidence-based, family-centered intervention program. Clinical practice guidelines (CPGs) for pediatric hearing assessment and hearing aid verification aim to reduce variability in practice and increase the use of effective evidence-based diagnostic and treatment options so that optimal outcomes may be achieved. To be of value, guidelines must be translated and implemented into practice and ongoing monitoring of their use in practice should occur. This paper provides the results of two studies that aim to examine current pediatric audiology and amplification practice in North America. A concurrent embedded mixed methods design was used. An electronic survey was distributed to North American audiologists who delivered pediatric audiology services with 350 audiologists participating in study 1 and 63 audiologists participating in study 2. A quantitative approach was the predominant method of data collection. Respondents were prompted to provide additional qualitative text and detail regarding their quantitative response choice. This qualitative text was used during the analysis phase and combined with quantitative results to assist understanding of respondents' knowledge, skills, and barriers/facilitators to implement best practice in pediatric amplification. Approximately 70% of audiologists reported using best-practice protocols for pediatric hearing aid fitting. Despite widespread knowledge and increased use of CPGs over the last 18 yrs, results of these studies show that variation in practice patterns continue to exist. Several examples of implementation challenges are discussed with recommendations provided. In order for audiologists working with children who are deaf or hard of hearing and their families to achieve the principles of family-centered early intervention, practice guidelines must continue to be developed, disseminated, and translated as they have a positive impact on the services provided. Researchers and clinical audiologists who deliver services must continue to collaborate to understand the "how" and "why" of implementing guidelines into practice and to identify the barriers/facilitators encountered in trying to do so.

O'Brien, Ian; Driscoll, Tim; Ackermann, Bronwen

2012-01-01

Hearing conservation and noise exposure management for professional orchestras is a difficult issue resistant to standard control measures as used in other industries with excessive noise problems. Although there has been a great deal of research into this area in terms of the audiological status of musicians and their exposure to noise, there are relatively few industry-specific strategies that can be adopted by an orchestra looking to address these issues. Australia does not have a uniform approach to hearing conservation management in its orchestras; however, each orchestra actively grapples with the challenges of balancing legal, practical, and artistic concerns. This study systematically investigated hearing conservation practices, noise exposure management, and audiological screening protocols in eight professional orchestras. The research involved personal interviews with staff at each orchestra, including inspection of venues and facilities. While all these orchestras were aware of the risks and were actively taking significant steps to reduce noise exposure, a range of approaches, with varying degrees of effectiveness and understanding of the issue, were found across the sector. There was limited evidence of educational programs for either the musicians at risk of excessive noise exposure or the staff responsible for devising and implementing control measures. In addition, the reported use of adequate personal hearing protection by musicians was poor. As Australia has recently introduced a national approach to workplace health and safety, a similar approach to noise and audiological management across the country's orchestral sector is proposed, drawn from existing research and practice. This will enable both consistent procedures and meaningful dialogue between the orchestras on the topics of hearing conservation, audiological monitoring, and educational practices.

The anatomy and physiology of the ear is complex in nature, which makes it a challenge for audiologists to prescribe solutions for varied hearing-impaired subjects. There is a need to increase the satisfaction level of hearing-aid users by adopting better strategies that involve modern technological advancements. To design and develop a decision support Software Intelligent System (SIS) that performs audiological investigations to assess the degree of hearing loss and to suggest appropriate hearing-aid gain values. SIS is developed based on the study conducted in the Government General Hospital, Chennai, India, between 2013 and 2015. In the study period, audiological investigations were performed on 368 subjects, using the clinical audiometer (Inventis-Piano, Italy) and the SIS. Gain suggestions were recommended for hearing-aid users (Siemens Intuis life & Intuis-SP) using standard prescriptive procedures, alterations made by the audiologists, and by the SIS. It was developed with artificial neural network-based gain predictions. Of the tested subjects, 256 were identified as hearing-impaired. The calculated sensitivity, specificity and accuracy of the computerised audiometer incorporated in the SIS are 93%, 85% and 90% respectively. Furthermore, 86% of the hearing-impaired subjects were satisfied during their first hearing-aid trial with the gain recommendations from SIS. The findings suggest that the proposed SIS could be used to perform audiological screening tests and to recommend appropriate hearing-aid gain values to the hearing-impaired subjects. This could eventually be helpful for audiologists in the areas where routine mass audiological screening and fast hearing-aid solution is required. Copyright © 2016 Elsevier Ireland Ltd.

To identify primary biographic and audiologic factors contributing to cochlear implant (CI) performance variability in quiet and noise by controlling electrode array type and electrode position within the cochlea. Although CI outcomes have improved over time, considerable outcome variability still exists. Biographic, audiologic, and device-related factors have been shown to influence performance. Examining CI recipients with consistent array type and electrode position may allow focused investigation into outcome variability resulting from biographic and audiologic factors. Thirty-nine adults (40 ears) implanted for at least 6 months with a perimodiolar electrode array known (via computed tomography [CT] imaging) to be in scala tympani participated. Test materials, administered CI only, included monosyllabic words, sentences in quiet and noise, and spectral ripple discrimination. In quiet, scores were high with mean word and sentence scores of 76 and 87%, respectively; however, sentence scores decreased by an average of 35 percentage points when noise was added. A principal components (PC) analysis of biographic and audiologic factors found three distinct factors, PC1 Age, PC2 Duration, and PC3 Pre-op Hearing. PC1 Age was the only factor that correlated, albeit modestly, with speech recognition in quiet and noise. Spectral ripple discrimination strongly correlated with speech measures. For these recipients with consistent electrode position, PC1 Age was related to speech recognition performance. Consistent electrode position may have contributed to high speech understanding in quiet. Inter-subject variability in noise may have been influenced by auditory/cognitive processing, known to decline with age, and mechanisms that underlie spectral resolution ability.

Tele-diagnostic audiological testing in a hearing screening program for infants and young children is a novel practice, and this study is the first to explore its application in a rural community. It is important to understand parental perceptions and confidence when introducing a new process such as tele-audiological diagnostic testing in rural areas. A questionnaire with 17 rater-administered items was designed to elicit comments concerning the quality of tele-hearing testing and video-conferencing, access to tele-hearing testing, and parents' attitudes regarding tele-hearing testing in the village. The questionnaire was administered by an audiologist not involved in tele-diagnostic testing to avoid bias. Parents perceived tele-hearing testing as equal in quality to in-person testing. Technical factors such as good video-conferencing quality and logistical factors such as ease of access due to reasonable travel time to testing facility could have influenced these perceptions. While these results show tele-hearing testing is an acceptable alternative, occasional poor signal quality should be addressed prior to large-scale implementation.

Audiological characteristics were investigated in 81 ears of 53 infants with abnormal transient evoked otoacoustic emission (TEOAE) and normal auditory brainstem response (ABR). The relationship between ABR and other hearing testing methods, including 40Hz auditory event-related potential (40Hz-AERP), auditory steady state response (ASSR), distortion product otoacoustic emission (DPOAE), tympanometry, and acoustic reflex, was analyzed. Of the 81 ears, 18 ears (22.2%) were normal, while 63 ears (77.8%) were abnormal according to the tests. Testing of the 40 Hz AERP (36 ears) and ASSR (45 ears) revealed that 14 ears (38.9%) and 27 ears (60.0%) were abnormal, respectively. Testing of DPOAE in 68 ears revealed that 50 ears (73.5%) were abnormal. Testing of tympanometry in 50 ears and acoustic reflex in 47 ears revealed that 9 ears (18%) and 27 ears (57.4%) were abnormal, respectively. The present data suggests that the hearing of infants cannot be sufficiently evaluated with ABR only and that it must be evaluated with integrative audiological testing methods.

The nature of communication between patient and practitioner influences patient outcomes. Specifically, the history-taking phase of a consultation plays a role in the development of a relationship and in the success of subsequent shared decision making. There is limited research investigating patient-centered communication in audiology, and this study may be the first to investigate verbal communication in an adult audiologic rehabilitation context. This research aimed, first, to describe the nature of verbal communication involving audiologists, patients, and companions in the history-taking phase of initial audiology consultations and, second, to determine factors associated with communication dynamics. Sixty-three initial audiology consultations involving patients over the age of 55, their companions when present, and audiologists were audio-video recorded. Consultations were coded using the Roter Interaction Analysis System and divided into three consultation phases: history, examination, and counseling. This study analyzed only the history-taking phase in terms of opening structure, communication profiles of each speaker, and communication dynamics. Associations between communication dynamics (verbal dominance, content balance, and communication control) and 11 variables were evaluated using Linear Mixed Model methods. The mean length of the history-taking phase was 8.8 min (range 1.7 to 22.6). A companion was present in 27% of consultations. Results were grouped into three areas of communication: opening structure, information exchange, and relationship building. Examination of the history opening structure revealed audiologists' tendency to control the agenda by initiating consultations with a closed-ended question 62% of the time, followed by interruption of patient talk after 21.3 sec, on average. The aforementioned behaviors were associated with increased verbal dominance throughout the history and increased control over the content of questions. For the remainder of the history, audiologists asked 97% of the questions and did so primarily in closed-ended form. This resulted in the audiologist talking as much as the patient and much more than the companions when they were present. Questions asked by the audiologist were balanced in topic: biomedical and psychosocial/lifestyle; however, few emotionally focused utterances were observed from any speaker (less than 5% of utter ances). Analysis of verbal communication involving audiologists, patients, and companions in the history-taking phase in 63 initial audiology consultations revealed a communicative exchange that was audiologist-controlled and structured, but covered both medical and lifestyle content. Audiologists often attempted to create a relationship with their patients; however, little emotional relationship building occurred, which may have implications later in the consultation when management decisions are being made. These results are not in line with patient-centered communication principles. Further research and changes to clinical practice are warranted to transform patient-centered communication from an ideal to a reality.

The aim of the paper is to describe the knowledge of mothers in Durban, South Africa, regarding risk factors of hearing loss in infants and their awareness of audiology services, and to describe their cultural beliefs about the risk factors for hearing loss in infants. A descriptive survey design with quantitative methods of analysis were used. Conveniently sampled mothers (n=102) receiving postnatal care for their infants from eight provincial clinics within Durban consented to participate, yielding a response rate of 48%. A questionnaire was used to collect the data and the Cronbach α was calculated yielding a score of 0.835, indicating good internal consistency and reliability of the questionnaire. Sixty percent of the mothers were aware of risk factors, such as middle ear infections, ototoxic medication and consumption of alcohol during pregnancy. Seventy percent were unaware that NICU/mechanical ventilation for more than 5 days, prematurity, rubella and jaundice are considered risk factors for hearing loss, implying a need to create awareness amongst mothers regarding such risk factors. Sixty percent (n=62) believed that bewitchment and ancestral curses can cause hearing loss. Cultural beliefs were associated with hearing loss, therefore, health professionals need to demonstrate cultural competence when providing audiology services, especially in a culturally and linguistically diverse countries such as South Africa. Although the mothers had an average knowledge about risk factors, two thirds did not know which professional to seek help from. There is a need to create awareness amongst mothers regarding the risk factors of infant hearing loss as well as audiology services in order to facilitate early detection and intervention. There is a need for health professionals to demonstrate cultural competence when working with their patients. PMID:28890772

Cryopyrin-associated periodic syndromes (CAPS) represent a spectrum of CIAS1 gene-mediated autoinflammatory diseases characterized by recurrent systemic inflammation. The clinical spectrum of CAPS varies from mild to severe and includes the syndromes historically described as familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS), and neonatal-onset multisystem inflammatory disease (NOMID). This article presents the largest cohort of patients with CAPS. The objective is to describe the pathogenesis, otolaryngologic, and audiologic manifestations of CAPS. Prospective (2003-2009). National Institutes of Health. Fifty-seven patients with a diagnosis of CAPS were identified (31 NOMID, 11 NOMID/MWS, 9 MWS, and 6 FCAS). Comprehensive data regarding clinical manifestations, audiologic phenotype, and fluid attenuation inversion recovery MRI (FLAIR-MRI) of the brain and inner ear were obtained. Complete audiologic data obtained on 70% of ears revealed conductive hearing loss in 4 (11%) NOMID ears and mixed hearing loss in 5 (13%) NOMID and 2 (14%) NOMID/MWS ears. Sensorineural hearing loss (SNHL), worse in higher frequencies, was the most common type of hearing loss and was present in 23 (61%) NOMID, 10 (71%) NOMID/MWS, and 4 (33%) MWS ears. All of the patients with FCAS had normal hearing except 2, who had SNHL from 4 to 8 kHz. On FLAIR-MRI sequence, cochlear enhancement was noted in 26 of 29 (90%) NOMID, 6 of 11 (55%) NOMID/MWS, 3 of 9 (33%) MWS, and 1 of 6 (17%) FCAS patients and was significantly associated with the presence of hearing loss. Maxillary sinus hypoplasia and mucosal thickening were found in 39% and 86% of the cohort, respectively. CIAS1 pathway–mediated CAPS is associated with unregulated autoinflammation mediated by interleukin-1 in the cochlea and hearing loss. Timely diagnosis is crucial to initiate early treatment with interleukin-1 receptor antagonists.

Methods: This retrospective study evaluated 20 children ranging in age from 7 to 14 years at the time of audiological and electrophysiological evaluations. We performed periodic surveys of the lead concentration in the blood and basic audiological evaluations. Furthermore, we studied the auditory evoked potential long latency N2 and cognitive P3 by analyzing the absolute latency of the N2 and P3 potentials and the P3 amplitude recorded at Cz. At the time of audiological and electrophysiological evaluations, the average concentration of lead in the blood was less than 10 ug/dL. Results: In conventional audiologic evaluations, all children had hearing thresholds below 20 dBHL for the frequencies tested and normal tympanometry findings; the auditory evoked potential long latency N2 and cognitive P3 were present in 95% of children. No significant correlations were found between the blood lead concentration and latency (p = 0.821) or amplitude (p = 0.411) of the P3 potential. However, the latency of the N2 potential increased with the concentration of lead in the blood, with a significant correlation (p = 0.030). Conclusion: Among Brazilian children with low lead exposure, a significant correlation was found between blood lead levels and the average latency of the auditory evoked potential long latency N2; however, a significant correlation was not observed for the amplitude and latency of the cognitive potential P3.

The aim of the paper is to describe the knowledge of mothers in Durban, South Africa, regarding risk factors of hearing loss in infants and their awareness of audiology services, and to describe their cultural beliefs about the risk factors for hearing loss in infants. A descriptive survey design with quantitative methods of analysis were used. Conveniently sampled mothers (n=102) receiving postnatal care for their infants from eight provincial clinics within Durban consented to participate, yielding a response rate of 48%. A questionnaire was used to collect the data and the Cronbach α was calculated yielding a score of 0.835, indicating good internal consistency and reliability of the questionnaire. Sixty percent of the mothers were aware of risk factors, such as middle ear infections, ototoxic medication and consumption of alcohol during pregnancy. Seventy percent were unaware that NICU/mechanical ventilation for more than 5 days, prematurity, rubella and jaundice are considered risk factors for hearing loss, implying a need to create awareness amongst mothers regarding such risk factors. Sixty percent (n=62) believed that bewitchment and ancestral curses can cause hearing loss. Cultural beliefs were associated with hearing loss, therefore, health professionals need to demonstrate cultural competence when providing audiology services, especially in a culturally and linguistically diverse countries such as South Africa. Although the mothers had an average knowledge about risk factors, two thirds did not know which professional to seek help from. There is a need to create awareness amongst mothers regarding the risk factors of infant hearing loss as well as audiology services in order to facilitate early detection and intervention. There is a need for health professionals to demonstrate cultural competence when working with their patients.

Objective . To describe and quantify hearing impairment among children referred to the audiology clinic in Princess Marina Hospital, a public referral hospital in Botswana. Methods . In a retrospective case series, we reviewed medical records of children aged 10 years and younger whose hearing was assessed between January 2006 and December 2015 at the audiology clinic of Princess Marina Hospital in Gaborone, Botswana. Results . Of 622 children, 50% were male, and median age was 6.7 years (interquartile range = 5.0-8.3). Hearing impairment was diagnosed in 32% of clinic attendees, comprising sensorineural (23%), conductive (25%), and mixed (11%) hearing loss, while 41% of children with diagnosed hearing impairment did not have a classification type. Hearing impairment was mild in 22.9%, moderate in 22.4%, severe in 19.4%, profound in 16.9%, and of undocumented severity in 18.4%. Children younger than 5 years were 2.7 times (95% confidence interval = 1.29-5.49; P = .008) more likely to be diagnosed with sensorineural hearing impairment compared with those older than 5 years. By contrast, children older than 5 years were 9.6 times (95% confidence interval = 2.22-41.0; P = .002) more likely to be diagnosed with conductive hearing loss compared with those under 5 years. Conclusion . Hearing impairment was common among children referred to this audiology clinic in Botswana. Of those with hearing impairment, more than a third had moderate or severe deficits, suggesting that referrals for hearing assessments are not occurring early enough. Hearing awareness programs individually tailored to parents, educators, and health care workers are needed. Neonatal and school hearing screening programs would also be beneficial.

Audiological and electrophysiological evaluation of children with acquired immunodeficiency syndrome (AIDS).

We examined the peripheral auditory system and the auditory brainstem pathway of children with Acquired Immunodeficiency Syndrome (AIDS). One hundred and one children, 51 with AIDS diagnosis and 50 normal children were evaluated. Audiological assessment included immittance measures, pure tone and speech audiometry and auditory brainstem response (ABR). The children with AIDS more frequently had abnormal results than did their matched controls, presenting either peripheral or auditory brainstem impairment. We suggest that AIDS be considered a risk factor for peripheral and/or auditory brainstem disorders. Further research should be carried out to investigate the auditory effects of HIV infection along the auditory pathway.

Audiological Rehabilitation for Facilitating Hearing Aid Use: A Review.

PubMed

Aazh, Hashir; Moore, Brian C J

2017-03-01

This article reviews and critically analyzes the design of studies on the effect of audiological rehabilitation (AR) programs on hearing aid (HA) outcomes, in order to guide future research. The design of this study was a narrative review. Studies were included in the review if they were randomized controlled trials that investigated the effects of AR on HA use and outcome between 2000 and 2016. Seven articles that met the inclusion criteria were included in the review. Most used educational rather than counseling approaches. Although educational AR programs seem to be useful in enhancing the use of communication strategies, there is limited evidence for their effect on HA use and self-perceived hearing handicap. More research is needed in this field. Future studies should (1) investigate the efficacy of AR interventions based on counseling and empathetic listening as opposed to or in addition to educational interventions, (2) use stricter criteria to include only a subpopulation of patients who do not get on well with their HAs, (3) measure the amount of HA use via data-logging and self-report questionnaires, and (4) use a matching comparison intervention for patients in the control group.

Naudé, Alida Maryna; Bornman, Juan

2014-06-01

The purpose of this research was to apply multiple perspectives as part of a systematic review to analyze literature regarding ethics in audiology. Audiologists are particularly vulnerable to the changing requirements of the discipline that compel them to straddle both professional obligations and business principles, creating a hybrid professional. The authors used a 2-phase mixed-method approach to analyze publications. Publications were sorted into categories, namely, ethics approach, author, decade, role of the audiologist, component of morality, and common themes. The sample consisted of peer-reviewed articles cited in MEDLINE, CINAHL, ERIC, MasterFILE Premier, E-Journals, Africa-Wide Information, and Academic Search Premier electronic databases and non-peer-reviewed articles in Seminars in Hearing. The publications were predominantly philosophical, focused on the rehabilitative role of the audiologist, and addressed the moral judgment component of moral behavior. Despite the fact that knowledge of ethics grew between 1980 and 2010, this retrospective analysis identified gaps in current knowledge. Research is needed to address the unique ethical problems commonly encountered in all 8 roles of the audiologist; patient perspectives on ethics; ethical approaches; factors affecting moral judgment, sensitivity, motivation, and courage; and cultural dimensions of ethical practice in audiology.

This study explored the nature of audiological services for adults with hearing impairment in Malaysia, with an emphasis on whether current services address clients' overall functioning as described by the World Health Organisation's International Classification of Functioning, Disability, and Health (ICF) framework. An online survey exploring current practice, skills and confidence of audiologists, and the infrastructure and facilities available in their workplaces, was distributed to audiologists in Malaysia via professional associations and social media. A total of 111 audiologists, 84.7% female and 15.3% male (range = 23-44 years), participated in the study. Although audiologists in Malaysia reported addressing all of the ICF domains, less than 26% of them assessed the patients' speech perception, carried out real-ear measurements, or used outcome measures routinely. The majority of the audiologists reported feeling confident in managing adult patients. However, 83% of the audiologists indicated they wanted to improve their skills related to management of adult patients, particularly in the areas of counselling and auditory training. Inadequate infrastructure, resources and facilities in the workplace may have contributed to the gaps in service provision and influenced the current practice of audiological management for adult patients in Malaysia.

Psychological and audiological correlates of perceived tinnitus severity.

1992-01-01

Beliefs and attitudes towards tinnitus have been found to play an important role in the process of rehabilitation. The relationship between audiological, psychological and psychosomatic factors (self-assessment of vertigo and headache and the perceived severity of tinnitus) was investigated in a clinical population of 163 subjects. Audiological descriptives comprised pure-tone average (dB HL), etiology of hearing loss, duration of tinnitus and tinnitus localisation. Perceived severity of tinnitus was assessed with a questionnaire focusing on tinnitus impact on aspects of quality of life, concentration and sleep. A 28-item handicap and support questionnaire was used and factor analysed, resulting in three factors: perceived attitudes, social support and disability/handicap. Tinnitus severity was significantly related to perceived attitudes. The influence of social support on tinnitus severity did not seem to be crucial. The results showed that significantly more women than men complained about vertigo. Unilateral tinnitus localisation was also more prevalent in females. The subjects with multiple tinnitus localisations were older and had significantly more sleep disturbance than subjects with tinnitus localized to the ears only. In accordance with previously reported observations, the frequency of headaches was strongly correlated with the severity of tinnitus.

This article describes the perspectives of hearing device manufacturers regarding the exciting developments that the Internet makes possible. Specifically, it proposes to join forces toward interoperability and standardization of Internet and audiology. A summary of why such a collaborative effort is required is provided from historical and scientific perspectives. A roadmap toward interoperability and standardization is proposed. Information and communication technologies improve the flow of health care data and pave the way to better health care. However, hearing-related products, features, and services are notoriously heterogeneous and incompatible with other health care systems (no interoperability). Standardization is the process of developing and implementing technical standards (e.g., Noah hearing database). All parties involved in interoperability and standardization realize mutual gains by making mutually consistent decisions. De jure (officially endorsed) standards can be developed in collaboration with large national health care systems as well as spokespeople for hearing care professionals and hearing device users. The roadmap covers mutual collaboration; data privacy, security, and ownership; compliance with current regulations; scalability and modularity; and the scope of interoperability and standards. We propose to join forces to pave the way to the interoperable Internet and audiology products, features, and services that the world needs.

Individual Differences in Behavioral and Electrophysiological Measures of Binaural Processing Across the Adult Life Span.

PubMed

Roup, Christina M; Leigh, Elizabeth D

2015-06-01

The purpose of the present study was to examine individual differences in binaural processing across the adult life span. Sixty listeners (aged 23-80 years) with symmetrical hearing were tested. Binaural behavioral processing was measured by the Words-in-Noise Test, the 500-Hz masking level difference, and the Dichotic Digit Test. Electrophysiologic responses were assessed by the auditory middle latency response binaural interaction component. No correlations among binaural measures were found. Age accounted for the greatest amount of variability in speech-in-noise performance. Age was significantly correlated with the Words-in-Noise Test binaural advantage and dichotic ear advantage. Partial correlations, however, revealed that this was an effect of hearing status rather than age per se. Inspection of individual results revealed that 20% of listeners demonstrated reduced binaural performance for at least 2 of the binaural measures. The lack of significant correlations among variables suggests that each is an important measurement of binaural abilities. For some listeners, binaural processing was abnormal, reflecting a binaural processing deficit not identified by monaural audiologic tests. The inclusion of a binaural test battery in the audiologic evaluation is supported given that these listeners may benefit from alternative forms of audiologic rehabilitation.

The aim of this study was to evaluate audiologic properties of patients with Noonan syndrome and compare these findings with those of unaffected peers. The study included 17 children with Noonan syndrome and 20 typically developing children without Noonan syndrome. Pure tone and speech audiometry, immitancemetric measurement, otoacoustic emissions measurement and auditory brainstem response tests were applied to all (n = 37) children. Hearing thresholds of children with Noonan syndrome were higher (poorer) than those observed unaffected peers, while the hearing sensitivity of the both groups were normal limits (p = 0.013 for right, p = 0.031 for left ear). Transient evoked otoacoustic emissions amplitudes of the children with Noonan syndrome were lower than the children without Noonan syndrome (p = 0.005 for right, p = 0.002 for left ear). Middle ear pressures and auditory brainstem response values were within normal limits and there was no difference between the two groups (p > 0.05). General benefit of the present study is to characterize the audiologic findings of children with Noonan syndrome, which is beneficial in clinics evaluating children with Noonan syndrome.

Sebothoma, Ben; Kgare, Khomotjo S.

2017-01-01

Background The burden of hearing loss is on the increase, especially in low-income countries such as South Africa. The need for urgent action to prevent ear and hearing problems is a priority, especially as in many cases permanent hearing loss is preventable. In South Africa, as in other developing countries, there is a limited number of hearing health professionals and audiological resources. The lack of hearing health services may impact the general public’s awareness of hearing and hearing health. Limited information is available on the South African public’s knowledge of audiologists and the services they provide, especially in underserved rural communities. Aim The aim of this study was to describe individuals’ awareness of the audiology profession, hearing and hearing loss, and hearing health in a rural area of the Limpopo Province. Method A cross-sectional survey design was employed for the purpose of this study. Using a random sampling strategy, 297 households in four rural villages were selected and a self-developed questionnaire was administered to one individual (18 years and older) per household. The questionnaire consisted of 23 questions targeting awareness of the audiology profession, as well as knowledge of hearing, hearing loss and hearing health. Results Only 14% of participants were aware of the audiology profession, indicating that individuals living in rural communities are not aware of the role of audiologists and the services they provide. Doctors and nurses were identified by participants as the individuals who assist them with hearing-related problems. Although most participants (87%) acknowledged that it is very important to undergo a hearing test, only 5% have previously visited an audiologist. Most participants were aware that ear infections and excessive noise exposure can cause hearing loss. The majority also believed that ears must be kept clean at all times and used cotton buds to maintain ear hygiene. Conclusion There is a general lack of public awareness of audiologists and the services they offer. This study highlighted the need for the National Department of Health in collaboration with professional associations and hearing health professionals to develop and implement effective strategies to increase the South African public’s awareness of the profession and the services they provide. South African universities can also play a significant role in teaching students to develop context-relevant strategies to increase awareness of the profession. PMID:29041791

Thoughts about Suicide and Self-Harm in Patients with Tinnitus and Hyperacusis.

2018-03-01

There are conflicting reports with regard to the relationship between suicidal ideations and tinnitus and hyperacusis. Audiology departments play a major role in offering therapy and support for patients experiencing tinnitus and hyperacusis. If suicidal and self-harm ideations among patients seen in audiology clinics are high, then it would be important to screen for them to make onward referrals to mental health services. The aim of this study was to assess the prevalence of and factors related to suicidal and self-harm ideations in patients with tinnitus and hyperacusis seen at an audiology outpatient service. This study was a part of a service evaluation survey using a correlational design. All patients who sought help concerning their tinnitus or hyperacusis from an audiology clinic of the National Health Service in the United Kingdom in a 1-yr period were asked to complete the survey questionnaires (n = 402). The focus of this article is on analysis of the patients' responses about suicidal and self-harm ideations as measured via the Patient Health Questionnaire, item 9, and their associated factors. A total of 150/402 of patients answered the question about suicidal and self-harm ideations. Of these, 13% indicated that they had suicidal or self-harm ideations in the past 2 weeks. Suicidal and self-harm ideations were moderately correlated with scores on the anxiety and depression subscales of the hospital anxiety and depression scale. Suicidal and self-harm ideations decreased with increasing age. There were small statistically significant correlations between suicidal and self-harm ideations and tinnitus handicap, hyperacusis handicap, insomnia, and scores on the visual analog scale (VAS) of effect of tinnitus on life. The correlations between suicidal and self-harm ideations and gender, pure-tone average of the worse and better ears, uncomfortable loudness levels of the worse ears, and VAS of tinnitus loudness and annoyance were not statistically significant. A regression model showed that abnormal depression scores increased the chance of suicidal and self-harm ideations by a factor of 6.2 (95% confidence interval = 1.13-34.1, p = 0.036). Audiologists offering tinnitus and hyperacusis rehabilitation should screen for suicidal and self-harm ideations among patients, especially for those with comorbid depression, and make onward referral to appropriate services when needed.

A survey of auditory processing (AP) diagnostic practices was mailed to all licensed audiologists in the State of Maryland and sent as an electronic mail attachment to the American Speech-Language-Hearing Association and Educational Audiology Association Internet forums. Common AP protocols (25 from the Internet, 28 from audiologists in Maryland) included requiring basic audiologic testing, using questionnaires, and administering dichotic listening, monaural low-redundancy speech, temporal processing, and electrophysiologic tests. Some audiologists also administer binaural interaction, attention, memory, and speech-language/psychological/educational tests and incorporate a classroom observation. The various AP batteries presently administered appear to be based on the availability of AP tests with well-documented normative data. Resources for obtaining AP tests are listed.

To analysis the characteristics of audiology and clinical genetics of a Chinese family with the DFNA5 genetic hearing loss in detail. A detailed family history and clinical data were collected. The Chinese pedigree is an autosomal-dominant inherited hearing loss. The data of audiological examination about genetic characteristics was analysed. The relationship between the hearing-impaired of this family and age was contrasted. This Chinese family spanned five generations and comprised 42 members. The mode of inheritance of the families should be autosomal dominant according to the pedigree. Pure-tone audiograms showed a so-called Z shape curve. The hearing loss is sensorineural, progressive and beginning at the high frequencies. The audiograms were fairly symmetric. Whole frequencies became involved with increasing age. The Chinese family with the DFNA5 mutation was an autosomal dominant pedigree. In this family, non-syndromic symmetric hearing impairment was severest at the high frequencies early, and gradually accumulated all frequencies of hearing. A mutation in DFNA5 leads to a type of hearing loss that closely resembles the frequently observed age-related hearing impairment. It should take into account DFNA5 mutation which the audiogram of a genetic hearing impaired has the same feature.

The purpose of this study was to evaluate Interaural Attenuation (IA) in frequency base in the insert earphones that are used in audiological assessments. 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. 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. 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.

To assess cochlear involvement and hearing loss in patients with Behçet's disease (BD). Forty-two patients with BD and 24 sex and age matched healthy subjects were included in the study. pure-tone audiometry including high frequencies (250-16000Hz) and DPOAE were performed to all participants. Results of the audiological evaluation were compared and correlation between the audiologic status and clinical manifestations of the BD were investigated. Bilateral sensorineural hearing loss was detected in 27 (64.3%) patients. Hearing thresholds were found to be higher in patients with BD at all of the frequencies except at 500Hz when compared to control group (p<0.05). The difference in the hearing levels tend to increase in high frequencies. Compared with control group, distortion products and SNR of the BD patients were lower in all of the tested frequencies (p<0.05) which indicates weaker outer hair cell motility. There was no correlation between the clinical manifestations and the audiological parameters. Even having hearing levels within normal limits in speech frequencies, increased hearing thresholds in high frequencies and decreased signal-noise ratios (SNR) in distortion product otoacoustic emission (DPOAE) indicate a cochlear involvement in patients with BD.

Audiological parameters alone do not determine the choice to use hearing aids (HA). Subjective hearing-related QoL is a major factor that determines whether or not an older person will continue to wear HA. This study aimed to identify which audiological parameters and quality-of-life (QoL) measures determine whether or not older persons will continue wearing HA. Charts of 157 patients aged ≥65 years who attended the HA service unit at the Otolaryngology Department were retrospectively reviewed. After HA fitting and a trial, the patients were divided into groups, depending upon whether or not they wanted to continue wearing the HA (users, 58.2%; non-users, 41.8%) and then audiological parameters were compared between them. At least 4 months after the HA fitting, the self-reported QoL questionnaire, Hearing Handicap Inventory for the Elderly (HHIE), was mailed to all 157 patients and HHIE scores were compared between HA users and non-users. Speech discrimination score and dynamic range did not significantly differ between HA users and non-users. A difference in the average hearing threshold was marginally significant. The response rate to the HHIE was 65.2%. Total HHIE and emotional scores were higher (more impaired) among HA users than non-users.

Objective Cryopyrin-associated periodic syndromes (CAPS) represent a spectrum of CIAS1 gene-mediated autoinflammatory diseases characterized by recurrent systemic inflammation. The clinical spectrum of CAPS varies from mild to severe and includes the syndromes historically described as familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS), and neonatal-onset multisystem inflammatory disease (NOMID). This article presents the largest cohort of patients with CAPS. The objective is to describe the pathogenesis, otolaryngologic, and audiologic manifestations of CAPS. Study Design Prospective (2003–2009). Setting National Institutes of Health. Subjects and Methods Fifty-seven patients with a diagnosis of CAPS were identified (31 NOMID, 11 NOMID/MWS, 9 MWS, and 6 FCAS). Comprehensive data regarding clinical manifestations, audiologic phenotype, and fluid attenuation inversion recovery MRI (FLAIR-MRI) of the brain and inner ear were obtained. Results Complete audiologic data obtained on 70% of ears revealed conductive hearing loss in 4 (11%) NOMID ears and mixed hearing loss in 5 (13%) NOMID and 2 (14%) NOMID/MWS ears. Sensorineural hearing loss (SNHL), worse in higher frequencies, was the most common type of hearing loss and was present in 23 (61%) NOMID, 10 (71%) NOMID/MWS, and 4 (33%) MWS ears. All of the patients with FCAS had normal hearing except 2, who had SNHL from 4 to 8 kHz. On FLAIR-MRI sequence, cochlear enhancement was noted in 26 of 29 (90%) NOMID, 6 of 11 (55%) NOMID/MWS, 3 of 9 (33%) MWS, and 1 of 6 (17%) FCAS patients and was significantly associated with the presence of hearing loss. Maxillary sinus hypoplasia and mucosal thickening were found in 39% and 86% of the cohort, respectively. Conclusion CIAS1 pathway–mediated CAPS is associated with unregulated autoinflammation mediated by interleukin-1 in the cochlea and hearing loss. Timely diagnosis is crucial to initiate early treatment with interleukin-1 receptor antagonists. PMID:21493283

This study compares rates and timing of newborn hearing screening outcomes, audiological assessment and hearing loss diagnosis between infants of different gestational age groups. Early identification and management of sensorineural hearing loss (SNHL), ideally by 3-6 months of age, facilitates speech and language optimisation. Literature stratifying hearing screening and diagnostic audiology assessment by gestational age groups is lacking. Subjects were infants with recorded gestational ages receiving newborn hearing screening in Queensland between 2009 and 2011. Data were provided through the Queensland Healthy Hearing database. Infants were analysed in <34 weeks, 34-36 +6 weeks, 37-38 +6 weeks and ≥39 weeks gestational age groups. Infants (175 911) were eligible for analysis, 7.9% being preterm. Per 1000 infants analysed, bilateral SNHL of >40 dB occurred in 2.4 for <34, 1.4 for 34-36 +6 , 0.7 for 37-38 +6 and 0.7 for ≥39 weeks gestation. Diagnoses attributable to newborn hearing screening direct referral were 93.1% for bilateral >40 dB SNHL and 88.2% for other hearing loss. Relative to term, preterm infants had a higher incidence of direct and targeted surveillance referrals, audiology assessment and hearing loss diagnosis. Preterm infants were screened later after birth. Specific hearing screening and diagnosis characteristics differed between preterm infants <34 and 34-36 +6 weeks gestation, and term infants. Consideration of unique gestational age strata characteristics supports care individualisation. Preterm infants represent a diagnostic challenge, with higher rates of bilateral >40 dB SNHL than term but correspondingly higher false positive results on screening, justifying vigilant monitoring. Focused research into specific risk factors in preterm infants is warranted. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

Ninety-seven children who were born between 1954 and 1986 and presented to the Visually Impaired Program of British Columbia's Children's Hospital, Vancouver, Canada, with a primary ophthalmologic diagnosis of cataracts, were assessed neurologically, ophthalmologically, audiologically, and developmentally. Causal factors included prenatal infection (35 cases), hereditary cataracts (22 cases), various syndromes and metabolic disorders (9 cases), trauma (1 case), and unknown (30 cases). Ninety children were diagnosed to have congenital cataracts while 7 acquired them. Findings indicated that prenatal infection continues to be a cause of infantile cataracts, despite rubella immunization; that prematurity is not, as has been stated in the past, a cause of infantile cataract; and that careful neurological, audiological, and developmental examination is vital in the assessment of likely causes of this condition.

Internet application to tele-audiology--"nothin' but net".

PubMed

Givens, Gregg D; Elangovan, Saravanan

2003-12-01

The Telehealth program at East Carolina University has developed a system for real-time assessment of auditory thresholds using computer driven control of a remote audiometer via the Internet. The present study used 45 adult participants in a double-blind study of 2 different systems: a conventional audiometer and an audiometer operated remotely via the Internet. The audiometric thresholds assessed by these 2 systems varied by no more than 1.3 dB for air conduction and 1.2 dB for bone conduction. The results demonstrated the feasibility of this new "telehearing" audiometric system. With the rapid development of Internet-based applications, telehealth has the potential to provide important healthcare coverage for rural areas where specialized audiological services are lacking.

Experiential instruction in graduate-level preparation of speech-language pathology students in outer and middle ear screening.

PubMed

Serpanos, Yula C; Senzer, Deborah

2015-05-01

This study presents a piloted training model of experiential instruction in outer and middle ear (OE-ME) screening for graduate speech-language pathology students with peer teaching by doctor of audiology (AuD) students. Six individual experiential training sessions in screening otoscopy and tympanometry were conducted for 36 graduate-level speech-language pathology students led by a supervised AuD student. Postexperiential training, survey outcomes from 24 speech-language pathology students revealed a significant improvement (p = .01) in perceptions of attaining adequate knowledge and comfort in performing screening otoscopy (handheld and video otoscopy) and tympanometry. In a group of matched controls who did not receive experiential training in OE-ME screening (n = 24), ratings on the same learning outcomes survey in otoscopy and tympanometry were significantly poorer (p = .01) compared with students who did receive experiential training. A training model of experiential instruction for speech-language pathology students by AuD students improved learning outcomes, illustrating its promise in affecting clinical practices. The instructional model also meets the Council on Academic Accreditation in Audiology and Speech-Language Pathology (CAA; American Speech-Language-Hearing Association, 2008) and American Speech-Language-Hearing Association (2014) Certificate of Clinical Competence (ASHA CCC) standards for speech-language pathology in OE-ME screening and CAA (2008) and ASHA (2012) CCC standards in the supervisory process for audiology.

Telepractice has emerged as a form of service delivery to assess and treat individuals with communication disorders. The present study surveyed speech-language pathologists and audiologists in India about the use of telepractice. Two hundred and five (N=205) speech-language pathologists and audiologists responded to a questionnaire, with 12.19% reporting their use of telepractice to deliver clinical services. Respondents also indicated an urgent shortage of professionals in India to deliver clinical services in speech-language pathology and audiology, and opined that these needs can be met via the use of telepractice. India is well known throughout the world for the advanced application of Information and Communication Technology (ICT), with 931.95 million telephone subscribers, over 900 million mobile phone users, and the second-largest mobile phone usage in the world. India has also experienced a tremendous rise in the number of internet users. Therefore, India is well poised to fully develop telepractice to overcome the barriers of distance and amplify the availability of speech-language pathology, audiology and other healthcare services. But first, the widespread use of telepractice throughout the nation will require an improved infrastructure (e.g., to uphold privacy and security); training for professionals; and telepractice policies. While very promising, the deployment of telepractice throughout India will require the attention of policy makers and government organizations.

To compare two different percutaneous bone-anchored hearing aid (BAHA) abutment systems regarding operation time, scar healing, quality of life, implant stability, audiologic results, and complications. The study involves a prospective multi-center clinical evaluation. Thirty-two consecutive patients who had undergone BAHA surgery from January 2011 to January 2013 in two tertiary centers were included in the study. The Glasgow Inventory Benefit Score was used to assess the patients at least 6 months after surgery. The operation time and complications were recorded. Implant stability quotient (ISQ) values were recorded using resonance frequency analysis. Holger's classification was used to evaluate skin reactions. The mean length of the operation was 39.2±4 min for standard abutment and 18.3±5.7 min for hydroxyapatite-coated abutment. ISQ scores were significantly better for standard abutment in all tests. The mean total Glasgow Inventory Benefit Score was 39.3±19 for the standard abutment and 46.3±24.5 for the hydroxyapatite-coated abutment groups, but there was no statistical significance between the two groups. There was no difference in audiological improvement between the two groups after surgery. Hydroxyapatite-coated abutment provided a shorter operation time that was significantly different from standard abutment. There were no significant differences between standard abutment and hydroxyapatite-coated abutment regarding audiologic improvement, quality of life, loading time, and complications.

Simultaneous bilateral cochlear implantation in a five-month-old child with Usher syndrome.

PubMed

Alsanosi, A A

2015-09-01

To report a rare case of simultaneous bilateral cochlear implantation in a five-month-old child with Usher syndrome. Case report. A five-month-old boy with Usher syndrome and congenital profound bilateral deafness underwent simultaneous bilateral cochlear implantation. The decision to perform implantation in such a young child was based on his having a supportive family and the desire to foster his audiological development before his vision deteriorated. The subject experienced easily resolvable intra- and post-operative adverse events, and was first fitted with an externally worn audio processor four weeks after implantation. At 14 months of age, his audiological development was age-appropriate. Simultaneous bilateral cochlear implantation is possible, and even advisable, in children as young as five months old when performed by an experienced implantation team.

Hearing disability and communication handicap for compensation purposes based on self-assessment and audiometric testing.

PubMed

Salomon, G; Parving, A

1985-01-01

It is reasoned that for compensation or epidemiological studies an evaluation of hearing disability and the concomitant handicap must include the ability to perceive visual cues. A scaling procedure for hearing- and audiovisual communication handicap is presented. The procedure deviates in two ways from previous handicap assessments: (1) It is based on individual self-assessment of semantic speech perception but can be implemented by means of professional audiological test procedures. (2) The system does not make use of pure-tone auditory thresholds as a predominant audiological principle, but is based on speech perception. The interrelationship between auditory and audiovisual handicap is evaluated. A total score including audio- and audiovisual perception handicap is proposed and a suggestion for disability percentages is presented.

Psychophysical Map Stability in Bilateral Sequential Cochlear Implantation: Comparing Current Audiology Methods to a New Statistical Definition.

2015-01-01

The purpose of this study was to establish a statistical definition for stability in cochlear implant maps. Once defined, this study aimed to compare the duration taken to achieve a stable map in first and second implants in patients who underwent sequential bilateral cochlear implantation. This article also sought to evaluate a number of factors that potentially affect map stability. A retrospective cohort study of 33 patients with sensorineural hearing loss who received sequential bilateral cochlear implantation (Cochlear, Sydney, Australia), performed by the senior author. Psychophysical parameters of hearing threshold scores, comfort scores, and the dynamic range were measured for the apical, medial, and basal portions of the cochlear implant electrode at a range of intervals postimplantation. Stability was defined statistically as a less than 10% difference in threshold, comfort, and dynamic range scores over three consecutive mapping sessions. A senior cochlear implant audiologist, blinded to implant order and the statistical results, separately analyzed these psychophysical map parameters using current assessment methods. First and second implants were compared for duration to achieve stability, age, gender, the duration of deafness, etiology of deafness, time between the insertion of the first and second implant, and the presence or absence of preoperative hearing aids were evaluated and its relationship to stability. Statistical analysis included performing a two-tailed Student's t tests and least squares regression analysis, with a statistical significance set at p ≤ 0.05. There was a significant positive correlation between the devised statistical definition and the current audiology methods for assessing stability, with a Pearson correlation coefficient r = 0.36 and a least squares regression slope (b) of 0.41, df(58), 95% confidence interval 0.07 to 0.55 (p = 0.004). The average duration from device switch on to stability in the first implant was 87 days using current audiology methods and 81 days using the statistical definition, with no statistically significant difference between assessment methods (p = 0.2). The duration to achieve stability in the second implant was 51 days using current audiology methods and 60 days using the statistical method, and again no difference between the two assessment methods (p = 0.13). There was a significant reduction in the time to achieve stability in second implants for both audiology and statistical methods (p < 0.001 and p = 0.02, respectively). There was a difference in duration to achieve stability based on electrode array region, with basal portions taking longer to stabilize than apical in the first implant (p = 0.02) and both apical and medial segments in second implants (p = 0.004 and p = 0.01, respectively). No factors that were evaluated in this study, including gender, age, etiology of deafness, duration of deafness, time between implant insertion, and the preoperative hearing aid status, were correlated with stability duration in either stability assessment method. Our statistical definition can accurately predict cochlear implant map stability when compared with current audiology practices. Cochlear implants that are implanted second tend to stabilize sooner than the first, which has a significant impact on counseling before a second implant. No factors evaluated affected the duration required to achieve stability in this study.

Efficacy of carnitine in treatment of tinnitus: evidence from audiological and MRI measures-a case study.

Tinnitus, or ringing in the ears, is an extremely common ear disorder. However, it is a phenomenon that is very poorly understood and has limited treatment options. The goals of this case study were to identify if the antioxidant acetyl-L-carnitine (ALCAR) provides relief from tinnitus, and to identify if subjective satisfaction after carnitine treatment is accompanied by changes in audiological and imaging measures. Case Study. A 41-yr-old female with a history of hearing loss and tinnitus was interested in exploring the benefits of antioxidant therapy in reducing her tinnitus. The patient was evaluated using a standard audiological/tinnitus test battery and magnetic resonance imaging (MRI) recordings before carnitine treatment. After her physician's approval, the patient took 500 mg of ALCAR twice a day for 30 consecutive days. The audiological and MRI measures were repeated after ALCAR treatment. Pure-tone audiometry, tympanometry, distortion-product otoacoustic emissions, tinnitus questionnaires (Tinnitus Handicap Inventory and Tinnitus Reaction Questionnaire), auditory brainstem response, functional MRI (fMRI), functional connectivity MRI, and cerebral blood flow evaluations were conducted before intake of ALCAR and were repeated 30 days after ALCAR treatment. The patient's pretreatment pure-tone audiogram indicated a mild sensorineural hearing loss at 6 kHz in the right ear and 4 kHz in the left ear. Posttreatment evaluation indicated marginal improvement in the patient's pure-tone thresholds, but was sufficient to be classified as being clinically normal in both ears. Distortion-product otoacoustic emissions results showed increased overall emissions after ALCAR treatment. Subjective report from the patient indicated that her tinnitus was less annoying and barely noticeable during the day after treatment, and the posttreatment tinnitus questionnaire scores supported her statement. Auditory brainstem response peak V amplitude growth between stimulus intensity levels of 40-80 dB nHL indicated a reduction in growth for the posttreatment condition compared with the pretreatment condition. This was attributed to a possible active gating mechanism involving the auditory brainstem after ALCAR treatment. Posttreatment fMRI recordings in response to acoustic stimuli indicated a statistically significant reduction in brain activity in several regions of the brain, including the auditory cortex. Cerebral blood flow showed increased flow in the auditory cortex after treatment. The functional connectivity MRI indicated increased connectivity between the right and left auditory cortex, but a decrease in connectivity between the auditory cortex and some regions of the "default mode network," namely the medial prefrontal cortex and posterior cingulate cortex. The changes observed in the objective and subjective test measures after ALCAR treatment, along with the patient's personal observations, indicate that carnitine intake may be a valuable pharmacological option in the treatment of tinnitus.

Managing chronic tinnitus is challenging, and innovative ways to address the resulting health-care burden are required. Internet-based cognitive behavioral therapy (iCBT) for tinnitus shows promise as a cost-effective treatment option. The feasibility and effectiveness of iCBT in the United Kingdom are yet to be explored. Furthermore, it is not known if iCBT can be supported by an audiologist rather than a psychologist. This study aimed to determine the feasibility of guided iCBT using audiological support on tinnitus distress and tinnitus-related comorbidities. Furthermore, it aimed to establish the feasibility of iCBT for tinnitus distress in the United Kingdom, by determining recruitment, attrition, and compliance rates. Finally, it aimed to identify which aspects of the protocol require refinement for subsequent clinical trials. A single-group open trial design was implemented. This study would serve as a prerequisite study, to identify barriers, before undertaking effectiveness trials. Participants consisted of 37 adults (18 males, 19 females), with an age range of between 50 and 59 yr. The mean preintervention tinnitus severity rating was 56.15 (standard deviation = 18.35), which is categorized as "severe tinnitus" as measured by the Tinnitus Functional Index (TFI). Five participants withdrew during the study, and 29 of the remaining participants completed the postintervention questionnaire. The guided iCBT intervention ran over an eight-week period and consisted of 16 obligatory modules and five optional modules. The intervention was designed to be interactive, interesting, and stimulating. A key element was the provision of support from an audiologist throughout the program. Online questionnaires were used throughout the study. These were administered at baseline and postintervention to determine attrition and compliance rates and to facilitate sample size estimates for further clinical trials. Outcome measures for tinnitus severity, hearing handicap, insomnia, cognitive functioning, hyperacusis, anxiety, depression, and life satisfaction were used to investigate the effects of iCBT with audiological support. In addition, a weekly questionnaire was incorporated to monitor change in tinnitus distress while undertaking the intervention. Feasibility was established using an audiologist to support this guided iCBT intervention, as a significant change postintervention was found for tinnitus severity, as measured by the TFI and the Tinnitus Handicap Inventory, Screening version. The attrition rate was 22% and compliance was variable. Although these results were based on a small sample, they provide encouraging evidence for the feasibility of delivering iCBT treatment for tinnitus symptoms with audiology support in the United Kingdom. An Internet-based intervention of tinnitus appears to be feasible in the United Kingdom when using audiological support. Randomized controlled trials to further investigate the effectiveness of iCBT for tinnitus in the United Kingdom are required. American Academy of Audiology

The field of speech-language pathology (SLP) in Brazil, named 'fonoaudiologia', comprises both a therapeutic approach to communication disorders and audiology and was officially recognized on December 9, 1981 (law No. 6965). University programs exist since the 1960s. The undergraduate level is a 4-year honors Bachelor of Science program and requires at least a 3,700 h of coursework. Since 1996 four areas of specialization were established: language, audiology, voice and oral myology, requiring a minimum of 500 h of course. Graduate programs in the narrower sense,master's degree and doctorate, exist since the 1970s. Brazil is a 180-million inhabitant country with approximately 25,000 speech-language pathologists, of which 2,700 are specialists, 800 masters and 210 doctors. There are almost 100 undergraduate programs and 70 specialization courses; however, for master's degree and doctorate purposes there are only 8. Copyright (c) 2006 S. Karger AG, Basel.

2017-12-01

The purpose of this review is to determine the scope of peer-reviewed empirical research related to counselling in audiology with patients using hearing technology and to identify limitations and gaps to guide recommendations for future research. A rapid evidence assessment was used to identify relevant articles for the review. Eighteen articles met the inclusion criteria. Three themes were identified: (1) audiologist counselling perspectives, (2) counselling communication trends in practice and (3) audiologist experiences with professional training and reported patient outcomes. Findings revealed audiologists are more confident providing information than counselling that addresses adjustment aspects, and other communication gaps have been observed. There is limited research related to counselling in audiology. Audiologists continue to report a need for more training in counselling in their graduate programmes. Additional research is needed to determine effective ways to implement counselling in practice and to improve graduate student supervision for the development of counselling competencies and confidence in using skills in practice.

Using therapeutic sound with progressive audiologic tinnitus management.

PubMed

Henry, James A; Zaugg, Tara L; Myers, Paula J; Schechter, Martin A

2008-09-01

Management of tinnitus generally involves educational counseling, stress reduction, and/or the use of therapeutic sound. This article focuses on therapeutic sound, which can involve three objectives: (a) producing a sense of relief from tinnitus-associated stress (using soothing sound); (b) passively diverting attention away from tinnitus by reducing contrast between tinnitus and the acoustic environment (using background sound); and (c) actively diverting attention away from tinnitus (using interesting sound). Each of these goals can be accomplished using three different types of sound-broadly categorized as environmental sound, music, and speech-resulting in nine combinations of uses of sound and types of sound to manage tinnitus. The authors explain the uses and types of sound, how they can be combined, and how the different combinations are used with Progressive Audiologic Tinnitus Management. They also describe how sound is used with other sound-based methods of tinnitus management (Tinnitus Masking, Tinnitus Retraining Therapy, and Neuromonics).

2017-01-01

Health-care service delivery models have evolved from a practitioner-centered approach toward a patient-centered ideal. Concurrently, increasing emphasis has been placed on the use of empirical evidence in decision-making to increase clinical accountability. The way in which clinicians use empirical evidence and client preferences to inform decision-making provides an insight into health-care delivery models utilized in clinical practice. The present study aimed to investigate the sources of information audiologists use when discussing rehabilitation choices with clients, and discuss the findings within the context of evidence-based practice and patient-centered care. To assess the changes that may have occurred over time, this study uses a questionnaire based on one of the few studies of decision-making behavior in audiologists, published in 1989. The present questionnaire was completed by 96 audiologists who attended the World Congress of Audiology in 2014. The responses were analyzed using qualitative and quantitative approaches. Results suggest that audiologists rank clinical test results and client preferences as the most important factors for decision-making. Discussion with colleagues or experts was also frequently reported as an important source influencing decision-making. Approximately 20% of audiologists mentioned utilizing research evidence to inform decision-making when no clear solution was available. Information shared at conferences was ranked low in terms of importance and reliability. This study highlights an increase in awareness of concepts associated with evidence-based practice and patient-centered care within audiology settings, consistent with current research-to-practice dissemination pathways. It also highlights that these pathways may not be sufficient for an effective clinical implementation of these practices.

Auditory neuropathy spectrum disorder (ANSD) is a type of hearing disorder which is challenging for assessment and rehabilitation. This disorder has been studied over a decade and prevalence of the disorder is variable. The study aimed at estimating the prevalence and audiological characteristics of ANSD in children. A retrospective study was conducted from the medical records of pediatric patients evaluated at Rajiv Gandhi Government General Hospital and Madras Medical College, Chennai to estimate the prevalence of ANSD. Medical records of 2,624 children evaluated during the period of November 2010 to October 2012 within the age range of 6 months to 12 years were analyzed. Out of 2,624 pediatric population assessed 217 (8.26 %) of them had unilateral or bilateral sensory neural hearing loss with varying degrees. Out of 217 children with sensory neural hearing loss 5.06 % (N = 11) had ANSD. Audiological characteristics varied among the group. Children with ANSD had varied degree of hearing thresholds from normal to profound hearing impairment. All of them had 'A' type tympanogram with absent stapedial reflexes. DPOAEs or TEOAEs were observed in 54 % of population with ANSD. All of them had abnormal auditory brainstem responses (ABR). Replicable cochlear microphonics was observed in 46 % of children with ANSD. These results indicate that ANSD is not a rare condition among children and we emphasize the use of objective tests like tympanometry, Stapedial Reflex test, otoacoustic emissions and ABR in routine hearing assessment procedure for all children to identify ANSD.

Reporting Newborn Audiologic Results to State EHDI Programs.

Chung, Winnie; Beauchaine, Kathryn L; Grimes, Alison; O'Hollearn, Tammy; Mason, Craig; Ringwalt, Sharon

All US states and territories have an Early Hearing Detection and Intervention (EHDI) program to facilitate early hearing evaluation and intervention for infants who are deaf or hard of hearing. To ensure efficient coordination of care, the state EHDI programs rely heavily on audiologists' prompt reporting of a newborn's hearing status. Several states have regulations requiring mandatory reporting of a newborn's hearing status. This is an important public health responsibility of pediatric audiologists. Reasons for failing to report vary. The Early Hearing Detection and Intervention-Pediatric Audiology Links to Services (EHDI) facility survey was used to inform reporting compliance of audiology facilities throughout the United States. The survey was disseminated via articles, newsletters, and call-to-action notices to audiologists. Among 1024 facilities surveyed, 88 (8.6%) reported that they did not report newborn's hearing findings to their state EHDI program. Not knowing how to report to the state EHDI program was the most frequently chosen reason (60%). However, among the 936 facilities that were compliant with the reporting requirements, 51 estimated that they reported less than two-third of all hearing evaluation results (5.4%). Some facilities did not report a normal-hearing result and some failed to report because they assumed another facility would report the hearing results. Survey results indicated that audiologists were compliant reporting hearing results to the state EHDI programs. However, there is room for improvement. Regular provider outreach and training by the state EHDI program is necessary to ensure those who are not reporting will comply and to clarify reporting requirements for those who are already compliant.

To validate diagnostic pure-tone audiometry in schools without a sound-treated environment using an audiometer that incorporates insert earphones covered by circumaural earcups and real-time environmental noise monitoring. A within-subject repeated measures design was employed to compare air (250 to 8000 Hz) and bone (250 to 4000 Hz) conduction pure-tone thresholds measured in natural school environments with thresholds measured in a sound-treated booth. 149 children (54% female) with an average age of 6.9 yr (SD = 0.6; range = 5-8). Average difference between the booth and natural environment thresholds was 0.0 dB (SD = 3.6) for air conduction and 0.1 dB (SD = 3.1) for bone conduction. Average absolute difference between the booth and natural environment was 2.1 dB (SD = 2.9) for air conduction and 1.6 dB (SD = 2.7) for bone conduction. Almost all air- (96%) and bone-conduction (97%) threshold comparisons between the natural and booth test environments were within 0 to 5 dB. No statistically significant differences between thresholds recorded in the natural and booth environments for air- and bone-conduction audiometry were found (p > 0.01). Diagnostic air- and bone-conduction audiometry in schools, without a sound-treated room, is possible with sufficient earphone attenuation and real-time monitoring of environmental noise. Audiological diagnosis on-site for school screening may address concerns of false-positive referrals and poor follow-up compliance and allow for direct referral to audiological and/or medical intervention.

Chronic suppurative otitis media (CSOM) is a chronic infection of the middle ear cleft. In sub-Saharan Africa >50% of cases occur in children <10 years of age. To describe the otological, audiological and bacteriological findings in children with CSOM. We conducted a prospective study at the Ear, Nose and Throat (ENT) Clinic at Universitas Academic Hospital between August 2009 and December 2010. We included all children with CSOM over this period. Patients underwent ENT and paediatric examination, and were tested for HIV. Pus swabs were taken after an ear toilet for routine microbiology, fungal and Mycobacterium tuberculosis culture. We performed audiological testing after the otorrhoea had resolved. Eighty-six children (113 ears) were included, with a median age of 4.6 years (range 1 - 12 years). The mean duration of otorrhoea was 161.7 weeks (range 4 - 572 weeks). Nine patients (10.5%) presented with coalescent mastoiditis and/or intracranial complications of CSOM. Of the 153 organisms identified; Gram-negative bacteria were present in 93 (82.3%) ears, with 94.8% of these being sensitive to quinolones. Only 1 case of tuberculous otitis media was identified. HIV infection was present in 54.6% of patients tested. There was a hearing loss in 44 (66.7%) of the tested affected ears. There was a long delay between the onset of symptoms and accessing ENT services. Most cases of CSOM were due to quinolone-sensitive Gram-negative aerobes. There was a high prevalence of cholesteatoma, hearing loss and other complications in children in this study.

Purpose Carboplatin-induced ototoxicity remains poorly defined but is of potential great consequence in children with retinoblastoma. We retrospectively assessed the incidence of ototoxicity and its risk factors in children with retinoblastoma who were treated with carboplatin. Patients and Methods We reviewed the audiologic test results of 60 patients with retinoblastoma who received front-line treatment with systemic carboplatin and vincristine according to the St Jude RET-3 protocol (n = 23) or best clinical management (n = 37). Ototoxicity was evaluated by three different grading systems. Results Twelve patients (20%) developed ototoxicity at some time after treatment initiation; however, ototoxicity resolved in two patients, and thus,10 patients (17%) had sustained hearing loss as documented at their most recent audiologic evaluation. Nine of these 10 patients had grade 3 or 4 ototoxicity, and nine patients were less than 6 months of age at the start of chemotherapy. Age at the start of chemotherapy was the only risk factor identified as a significant predictor of sustained hearing loss. Younger age was associated with an increased incidence of hearing loss. The different ototoxicity grading systems showed good overall agreement in the identification of patients with ototoxicity. Agreement was greatest between the Brock and Children's Cancer Group systems. Conclusion We found that young patients with retinoblastoma who were treated with systemic carboplatin had a higher incidence of ototoxicity than previously reported. Younger patients (< 6 months of age at the start of treatment) were more likely to have ototoxicity than were older patients. Children treated with carboplatin should routinely undergo thorough, long-term audiologic monitoring. PMID:22370329

Electrophysiological evaluation is a fundamental procedure for the diagnostic assessment of hearing loss during infancy; in these cases, information concerning threshold level and auditory perception is particularly useful to establish a correct hearing rehabilitation program (hearing aids and cochlear implants). Purpose of this study is to underline the role of auditory brainstem responses (ABR) and electrocochleography (EcochG) in the definition of hearing loss in a selected group of children, referred to the Audiology Department of the University Hospital of Ferrara, for a tertiary level audiological assessment. A retrospective study of the paediatric patient database at the Audiology Department of the University Hospital of Ferrara has been performed. In a period between January 2000 and December 2007, a total of 272 paediatric cases have been identified (544 ears). An EM 12 Mercury apparatus has been used for the electrophysiological threshold identification (ABR and EcochG). Recordings were carried out under general anaesthesia, in a protected enviroment. In 19 of the 272 paediatric cases selected--38 ears (7%), the results of threshold evaluation through ABR were uncertain. The Ecochg recording resulted crucial for the final diagnosis in terms of definition of the hearing threshold level, and it was then possible to ensure the better hearing rehabilitation strategy. ABR has to be considered the first choice in hearing assessment strategy, either for screening or for diagnosis in newborns as well as in non-collaborating children; ECochG still may be considered a reliable diagnostic tool.

To compare cognitive performance between children with cochlear implants (CI) and normal-hearing peers; provide information about correlations between cognitive performance, basic academic achievement, and medical/audiological and social background variables; and assess the predictor quality of these variables for cognition. Cross-sectional study with comparison group, diagnostic test assessment. Data were collected in the authors' clinic (children with CI) and in Austrian schools (normal-hearing children). Forty children with CI (of the initial 65 children eligible for this study), aged 7 to 11 years, and 40 normal-hearing children, matched by age and sex, were tested with (a) the Culture Fair Intelligence Test (CFIT); (b) the Number Sequences subtest of the Heidelberger Rechentest 1-4 (HRT); (c) Comprehension, (d) Coding, (e) Digit Span, and (f) Vocabulary subtests of HAWIK III (German WISC III); (g) the Corsi Block Tapping Test; (h) the Arithmetic Operations subtests of the HRT; and (i) Salzburger Lese-Screening (SLS, reading). In addition, medical, audiological, social, and educational data from children with CI were collected. The children with CI equaled normal-hearing children in (a), (d), (e), (g), (h), and (i) and performed significantly worse in (b), (c) and (f). Background variables correlate significantly with cognitive skills and academic achievement. Medical/audiological variables explain 44.3% of the variance in CFT1 (CFIT, younger children). Social variables explain 55% of CFT1 and 24.5% of the Corsi test. This study augments the knowledge about cognitive skills and academic skills of children with CI. Cognitive performance is dependent on the early feasibility to hear and the social/educational background of the family.

To compare the audiologic results of geriatric patients receiving cochlear implants with younger age groups and to evaluate the quality of life after cochlear implantation in the geriatric population by means of validated quality-of-life questionnaires. Cross-sectional study involving 89 postlingually deafened cochlear implant subjects. Tertiary referral center. A total of 89 postlingually deafened patients were included in the study, among which were 25 patients who were aged 70 years or older. All patients received a cochlear implant. Subjects were implanted with either the Laura, Nucleus 24, or Med-el Combi 40+ cochlear implant systems implementing the SPEAK, ACE, CIS, or CIS+ coding strategies. Speech recognition was determined by means of phonetically balanced monosyllabic word lists. The Hearing Handicap Inventory for Adults, the Glasgow Benefit Inventory, and the scale for the prediction of hearing disability in sensorineural hearing loss were used to quantify the quality of life. Mean audiologic performance for the three groups increased significantly after implantation (p < 0.001). Postoperative audiologic performance of the geriatric population led to useful hearing, but these scores were significantly lower than for the younger age groups (p = 0.002). However, the quality-of-life outcomes for the geriatric group were similar to those of the younger age groups (p = 0.411 for the Hearing Handicap Inventory for Adults; p = 0.886 for the Glasgow Benefit Inventory). The results of this study prove that cochlear implantation in the elderly provides improvements in quality of life and speech understanding, similar to those for younger adult cochlear implant recipients.

Sudden Sensorineural Hearing Loss in the Department of Defense.

PubMed

Hughes, Charlotte K; Fischer, Jakob; Esquivel, Carlos R; Laury, Adrienne M

2018-04-01

Objective The American Academy of Otolaryngology-Head and Neck Surgery Foundation clinical practice guideline (CPG) proposes recommendations regarding sudden sensorineural hearing loss (SSNHL). SSNHL is managed by primary care, emergency medicine, and otolaryngology providers in the Department of Defense (DoD). However, their adherence to this CPG is unknown. We sought to determine provider compliance and identify areas for improvement. Study Design Case series with chart review. Setting DoD's electronic medical record. Subjects and Methods Patients with SSNHL (N = 204) were treated between March 1, 2012, and September 30, 2015. Time from onset of symptoms to evaluation by primary care, emergency department, audiology, and otolaryngology providers and treatments were analyzed. Results The average interval from onset of symptoms to evaluation by a primary care or emergency department provider was 4.86 days (95% CI, 3.46-6.26). Time from presentation to ear, nose, and throat and audiologic evaluation was 15.26 days (95% CI, 12.34-18.20) and 14.16 days (95% CI, 11.31-17.01), respectively. Diagnostic workup included magnetic resonance imaging (n = 150, 73.5%), computed tomography (n = 28, 13.7%), and laboratory testing (n = 50, 24.5%). Oral steroids were used in 137 (67.2%) patients, with 78.8% treated with the recommended dose. Intratympanic steroids were utilized in 65 (31.9%) patients, with variable dosing. Conclusion The DoD is uniquely positioned to evaluate adherence to CPGs on national and international levels given the robust and standardized electronic medical record. Areas of improvement include timely identification of SSNHL with rapid referral to ear, nose, and throat and audiology providers; minimizing unnecessary imaging, laboratory testing, and medications; and correct dosing of oral and intratympanic steroids.

This study was performed to analyze clinical and audiologic characteristics of sensorineural tinnitus and to investigate the associating factors reflecting psychological aspects of stress and depression of the patients. This is a retrospective analytical study conducted in a tinnitus clinic of a tertiary referral center of a university hospital. The medical records of 216 patients suffering from sensorineural tinnitus were thoroughly evaluated to determine correlations between clinical and audiological characteristics, including age, sex, predisposing or etiologic factors, hearing levels up to extended high frequencies, and tinnitus severity. Psychological aspects of stress and depression were also evaluated and analyzed to seek the associations with tinnitus severity. All data were stored in our database bank and were statistically analyzed. Our study subjects showed a slight male predominance. The highest percentage of tinnitus was found in patients of 60-80 years old. Only 32.5 % of tinnitus patients were subjectively aware of their hearing loss, whereas 73 % of subjects had hearing deficits in some frequencies in their audiogram. Hearing impairments were of the low-frequency sensorineural type in 18.2 % of patients and were limited to the high frequencies in 77.9 % of patients. Tinnitus was unilateral in 51 % of patients and had a tonal nature in 45 % of patients. In total, 45.8 % of patients with high-frequency sensorineural hearing loss had high-pitched tinnitus. There were significant correlations between tinnitus severity, loudness and annoyance. Correlations with THI (Tinnitus Handicap Inventory) and Beck depression index scores were also found. Sensorineural tinnitus was related with hearing loss in some frequencies nevertheless of patients' own awareness of hearing loss. Loudness and annoyance of tinnitus seems to be two important factors reflecting psychological problems of patients' stress and depression.

Decision-Making in Audiology: Balancing Evidence-Based Practice and Patient-Centered Care

Health-care service delivery models have evolved from a practitioner-centered approach toward a patient-centered ideal. Concurrently, increasing emphasis has been placed on the use of empirical evidence in decision-making to increase clinical accountability. The way in which clinicians use empirical evidence and client preferences to inform decision-making provides an insight into health-care delivery models utilized in clinical practice. The present study aimed to investigate the sources of information audiologists use when discussing rehabilitation choices with clients, and discuss the findings within the context of evidence-based practice and patient-centered care. To assess the changes that may have occurred over time, this study uses a questionnaire based on one of the few studies of decision-making behavior in audiologists, published in 1989. The present questionnaire was completed by 96 audiologists who attended the World Congress of Audiology in 2014. The responses were analyzed using qualitative and quantitative approaches. Results suggest that audiologists rank clinical test results and client preferences as the most important factors for decision-making. Discussion with colleagues or experts was also frequently reported as an important source influencing decision-making. Approximately 20% of audiologists mentioned utilizing research evidence to inform decision-making when no clear solution was available. Information shared at conferences was ranked low in terms of importance and reliability. This study highlights an increase in awareness of concepts associated with evidence-based practice and patient-centered care within audiology settings, consistent with current research-to-practice dissemination pathways. It also highlights that these pathways may not be sufficient for an effective clinical implementation of these practices. PMID:28752808

There is an important need to evaluate whether rehabilitation services effectively address the needs of minority culture populations with North America's increasingly diverse population. The objective of this paper was therefore to review and assess the state of knowledge of barriers and facilitators to cultural competence in rehabilitation services. Our scoping review focused on cultural competence in rehabilitation services. Rehabilitation services included in this review were: audiology, speech-language pathology, physiotherapy, and occupational therapy. A search strategy was developed to identify relevant articles published from inception of databases until April 2015. Titles and abstracts were screened by two independent reviewers according to specific eligibility criteria with the use of a liberal-accelerated approach. Full-text articles meeting inclusion criteria were then screened. Key study characteristics were abstracted by the first reviewer, and findings were verified by the second reviewer. After duplicates were removed, 4303 citations were screened. Included articles suggest that studies on cultural competence occur most frequently in occupational therapy (n = 17), followed by speech language pathology (n = 11), physiotherapy (n = 6), and finally audiology (n = 1). Primary barriers in rehabilitation services include language barriers, limited resources, and cultural barriers. Primary facilitators include cultural awareness amongst practitioners, cultural awareness in services, and explanations of health care systems. To our knowledge, this review is the first to summarize barriers and facilitators to cultural competence in rehabilitation fields. Insufficient studies were found to draw any conclusions with regards to audiological services. Minimal perspectives based on patient/caregiver experiences in all rehabilitation fields underscore a research gap. Future studies should aim to explore both patient/caregiver and practitioner perspectives as such data can help inform culturally competent practices.

Childhood hearing impairment is a significant cause of disability in developing countries. Otitis media and meningitis are leading infectious causes of preventable hearing loss in children. It is estimated that the Pacific Islands have among the greatest global burden of childhood hearing impairment due to infectious causes, and yet there is currently very little in the research literature on pediatric hearing disorders in this region. (1) To review existing research literature on pediatric hearing impairment in the Pacific Islands, and (2) to present a public health approach to the development and improvement of childhood hearing services in the Pacific Islands. The primary tool was a comprehensive literature review. MEDLINE and ScienceDirect databases were searched for relevant journal articles. There was no limit on the date of publication. Any article reporting on hearing impairment in the Pacific Region was included. A total of 23 journal articles were found that satisfied the above inclusion criteria. The limited information available in the literature suggests that otitis media and vaccine-preventable infections are a significant cause of avoidable childhood hearing impairment in the Pacific Islands. Pediatric audiology services are limited in this region. Further research is required to develop effective public health programs that should reduce the burden of preventable childhood hearing loss in the Pacific Islands. There is limited information in the research literature on pediatric hearing impairment and audiology services in the Pacific Islands. Epidemiological data based on the WHO Ear and Hearing Disorders Survey Protocol are urgently needed, and the development of audiology services within the existing public and primary health care framework should reduce the burden of preventable hearing loss in the Pacific Islands.

My internship at Johnson Space Center, Houston TX comprised of working simultaneously in the Space Life Science Directorate (Clinical Services Branch, SD3) in Audiology and Hearing Conservation and in the Astromaterials Research and Exploration Sciences Directorate in the Orbital Debris Program Office (KX). The purpose of the project done to support the Audiology and Hearing Conservation Clinic (AuHCon) is to organize and analyze auditory test data that has been obtained from tests conducted onboard the International Space Station (ISS) and in Johnson Space Center's clinic. Astronauts undergo a special type of auditory test called an On-Orbit Hearing Assessment (OOHA), which monitors hearing function while crewmembers are exposed to noise and microgravity during long-duration spaceflight. Data needed to be formatted to assist the Audiologist in studying, analyzing and reporting OOHA results from all ISS missions, with comparison to conventional preflight and post-flight audiometric test results of crewmembers. Orbital debris is the #1 threat to manned spacecraft; therefore NASA is investing in different measurement techniques to acquire information on orbital debris. These measurements are taken with telescopes in different parts of the world to acquire brightness variations over time, from which size, rotation rates and material information can be determined for orbital debris. Currently many assumptions are taken to resolve size and material from observed brightness, therefore a laboratory (Optical Measurement Center) is used to simulate the space environment and acquire information of known targets suited to best model the orbital debris population. In the Orbital Debris Program Office (ODPO) telescopic data were acquired and analyzed to better assess the orbital debris population.

Enlarged vestibular aqueduct (EVA) is the commonest congenital anomaly found with imaging techniques in paediatric sensorineural hearing loss (SNHL). Our aim was to describe clinical and audiological findings in paediatric hearing loss associated to EVA. Retrospective review of 55 children with imaging-technique EVA findings from 2000 to 2009. Subjective and/or objective audiological tests were analysed and audiological findings related to clinical features were described. Thirty-seven patients (67.27%) showed bilateral EVA and 18 (32.72%) were unilateral. Hearing loss was bilateral in 46 (83.63%) patients and unilateral in 9 (16.36%). Mean age at diagnosis was 3.78 years. Fifty-three (96.36%) children showed SNHL (28 bilateral and profound), while 2 (3.63%) patients had mixed hearing loss. There were 3 cases of hearing loss progression, 2 fluctuations, 2 of them were asymmetric and 2 patients suffered from vestibular symptoms. Concomitant image findings were 6 cochlear hypoplasia, 2 enlarged internal auditory canals, 1 enlarged vestibule and 1 hypoplastic lateral semicircular canal. Six clinical syndromes were found (2 cases of Down's, and 1 each of Jacobsen, Pendred, Waardenburg and branchio-oto-renal). One child was positive for GJB2 mutation. Familial hearing loss was demonstrated on 12 (21.8%) cases. The clinical picture of hearing loss associated to EVA is characterised by great variability. It should be included in the differential diagnosis of unexplained mixed hearing loss. Familial and syndromic findings have to be taken into consideration in the diagnostic evaluations of such patients. Knowledge about the natural history of this illness is needed so as to give parents prognostic information. Copyright © 2010 Elsevier España, S.L. All rights reserved.

Investigation of potential cognitive tests for use with older adults in audiology clinics.

Cognitive declines in working memory and processing speed are hallmarks of aging. Deficits in speech understanding also are seen in aging individuals. A clinical test to determine whether the cognitive aging changes contribute to aging speech understanding difficulties would be helpful for determining rehabilitation strategies in audiology clinics. To identify a clinical neurocognitive test or battery of tests that could be used in audiology clinics to help explain deficits in speech recognition in some older listeners. A correlational study examining the association between certain cognitive test scores and speech recognition performance. Speeded (time-compressed) speech was used to increase the cognitive processing load. Two hundred twenty-five adults aged 50 through 75 years were participants in this study. Both batteries of tests were administered to all participants in two separate sessions. A selected battery of neurocognitive tests and a time-compressed speech recognition test battery using various rates of speech were administered. Principal component analysis was used to extract the important component factors from each set of tests, and regression models were constructed to examine the association between tests and to identify the neurocognitive test most strongly associated with speech recognition performance. A sequencing working memory test (Letter-Number Sequencing [LNS]) was most strongly associated with rapid speech understanding. The association between the LNS test results and the compressed sentence recognition scores (CSRS) was strong even when age and hearing loss were controlled. The LNS is a sequencing test that provides information about temporal processing at the cognitive level and may prove useful in diagnosis of speech understanding problems, and in the development of aural rehabilitation and training strategies.

Hearing and Balance Disorders in the State of Hawai‘i: Demographics and Demand for Services

Hearing and balance disorders affect people of all ages. Among children, hearing loss affects speech and language development, academic performance, and psychosocial development. Hearing loss in adults negatively impacts work productivity, cognitive function, and psychosocial status. Prevalence of hearing loss in children in Hawai‘i is higher than the national average. Research indicates that hearing loss is a prevalent condition among veterans and advanced age adults. This is of particular concern in Hawai‘i as the state is home to many military training facilities and has a large elderly population. In contrast to the higher than average prevalence of hearing loss in Hawai‘i, there is a relatively small number of practicing audiologists in the state. Audiologists are independent doctoral level professionals responsible for the assessment and non-medical management of hearing impairment, vestibular disorders, auditory processing disorder, auditory neuropathy, tinnitus, and related disorders. Currently, there is no formal audiology training program in Hawai‘i to meet the needs for current or future hearing health professionals. The Department of Communication Sciences and Disorders at the University of Hawai‘i at Mānoa is developing a proposal for a Doctor of Audiology (Au.D.) program to provide a comprehensive doctoral-level audiology curriculum and clinical training in order to graduate audiologists with knowledge and skills needed to serve people with hearing and balance disorders in Hawai‘i. This review article describes the current status of hearing and balance disorders and services in Hawai‘i and stresses the importance of early identification and intervention in remediating their effects in all ages, with a focus on the need for expanding hearing health services in Hawai‘i.

Simultaneous versus sequential bilateral cochlear implants in adults: Cost analysis in a US setting.

PubMed

Trinidade, Aaron; Page, Joshua C; Kennett, Sarah W; Cox, Matthew D; Dornhoffer, John L

2017-11-01

From a purely surgical efficiency point of view, simultaneous cochlear implantation (SimCI) is more cost-effective than sequential cochlear implantation (SeqCI) when total direct costs are considered (implant and hospital costs). However, in a setting where only SeqCI is practiced and a proportion of initially unilaterally implanted patients do not progress to a second implant, this may not be the case, especially when audiological costs are factored in. We present a cost analysis of such a scenario as would occur in our institution. Retrospective review and cost analysis. Between 2005 and 2015, 370 patients fulfilled the audiological criteria for bilateral implantation. Of those, 267 (72.1%) underwent unilateral cochlear implantation only, 101 (27.3%) progressed to SeqCI, and two underwent SimCI. The total hospital, surgical, and implant costs, and initial implant stimulation series audiological costs between August 2015 and August 2016 (29 adult patients) were used in this analysis. The total hospital, surgical, and implant costs for this period was $2,731,360.42. Based on previous local trends, if a projected eight (27.3%) of these patients decide to progress to SeqCI, this will cost an additional $750,811.04, resulting in an overall total of $3,482,171.46 for these 29 patients. Had all 29 undergone SimCI, the total projected cost would have been $3,332,991.75, representing a total potential saving of $149,179.67 (4.3%). In institutions where only SeqCI is allowed in adults, overall patient management may cost marginally more than if SimCI were practiced. This will be of interest to CI programs and health insurance companies. 4. Laryngoscope, 127:2615-2618, 2017. © 2017 The American Laryngological, Rhinological and Otological Society, Inc.

Self-administered hearing loss screening using an interactive, tablet play audiometer with ear bud headphones.

2015-08-01

The timely diagnosis and treatment of acquired hearing loss in the pediatric population has significant implications for a child's development. Audiological assessment in children, however, carries both technological and logistical challenges. Typically, specialized methods (such as play audiometry) are required to maintain the child's attention and can be resource intensive. These challenges were previously addressed by a novel, calibrated, interactive play audiometer for Apple(®) iOS(®) called "ShoeBOX Audiometry". This device has potential applications for deployment in environments where traditional clinical audiometry is either unavailable or impractical. The objective of this study was to assess the screening capability of the tablet audiometer in an uncontrolled environment using consumer ear-bud headphones. Consecutive patients presenting to the Audiology Clinic at the Children's Hospital of Eastern Ontario (ages 4 and older) were recruited. Participants' hearing was evaluted using the tablet audiometer calibrated to Apple(®) In-Ear headphones. The warble tone thresholds obtained were compared to gold standard measurements taken with a traditional clinical audiometer inside a soundbooth. 80 patients were enrolled. The majority of participants were capable of completing an audiologic assessment using the tablet computer. Due to ambient noise levels outside a soundbooth, thresholds obtained at 500Hz were not consistent with traditional audiometry. Excluding 500Hz threholds, the tablet audiometer demonstrated strong negative predictive value (89.7%) as well as strong sensitivity (91.2%) for hearing loss. Thresholds obtained in an uncontrolled setting are not reflective of diagnostic thresholds due to the uncalibrated nature of the headphones and variability of the setting without a booth. Nevertheless, the tablet audiometer proved to be both a valid and sensitive instrument for unsupervised screening of warble-tone thresholds in children. Copyright © 2015 Elsevier Ireland Ltd.

Crosscheck Principle in Pediatric Audiology Today: A 40-Year Perspective

PubMed Central

2016-01-01

The crosscheck principle is just as important in pediatric audiology as it was when first described 40 years ago. That is, no auditory test result should be accepted and used in the diagnosis of hearing loss until it is confirmed or crosschecked by one or more independent measures. Exclusive reliance on only one or two tests, even objective auditory measures, may result in a auditory diagnosis that is not clear or perhaps incorrect. On the other hand, close and careful analysis of findings for a test battery consisting of objective procedures and behavioral tests whenever feasible usually leads to prompt and accurate diagnosis of auditory dysfunction. This paper provides a concise review of the crosscheck principle from its introduction to its clinical application today. The review concludes with a description of a modern test battery for pediatric hearing assessment that supplements traditional behavioral tests with a variety of independent objective procedures including aural immittance measures, otoacoustic emissions, and auditory evoked responses.

Extended high-frequency audiometry (9,000-20,000 Hz). Usefulness in audiological diagnosis.

PubMed

Rodríguez Valiente, Antonio; Roldán Fidalgo, Amaya; Villarreal, Ithzel M; García Berrocal, José R

2016-01-01

Early detection and appropriate treatment of hearing loss are essential to minimise the consequences of hearing loss. In addition to conventional audiometry (125-8,000 Hz), extended high-frequency audiometry (9,000-20,000 Hz) is available. This type of audiometry may be useful in early diagnosis of hearing loss in certain conditions, such as the ototoxic effect of cisplatin-based treatment, noise exposure or oral misunderstanding, especially in noisy environments. Eleven examples are shown in which extended high-frequency audiometry has been useful in early detection of hearing loss, despite the subject having a normal conventional audiometry. The goal of the present paper was to highlight the importance of the extended high-frequency audiometry examination for it to become a standard tool in routine audiological examinations.

Assessing audiological, pathophysiological, and psychological variables in chronic tinnitus: a study of reliability and search for prognostic factors.

PubMed

Hiller, W; Goebel, G

1999-01-01

The development and course of chronic tinnitus are determined by both biological and psychological factors. To combine these different sources of data, we developed a standardized interview to assess tinnitus history, summarize audiological findings, screen for etiological conditions, and explore tinnitus-related psychological complaints (Structured Tinnitus Interview). The results of a test-retest study with 65 tinnitus inpatients show that most of these components can be assessed with acceptable or high reliability. Further data based on 166 patients demonstrate that tinnitus annoyance was to some extent different from patterns of general psychological complaints, although there were medium intercorrelations with depression. Significant predictors of tinnitus annoyance were (a) continuous tinnitus without intervals, (b) hearing loss, (c) increasing tinnitus loudness over time, (d) poor maskability, (e) history of sudden hearing loss, and (f) associated craniomandibular disorder. Psychological distress was not significantly increased in patients whose tinnitus was associated to vascular disorder, cervical spine dysfunction, acoustic trauma, Menihre's disease, or neurological disorder.

Spatial acoustic radiation of respiratory sounds for sleep evaluation.

PubMed

Shabtai, Noam R; Zigel, Yaniv

2017-09-01

Body posture has an effect on sleeping quality and breathing disorders and therefore it is important to be recognized for the completion of the sleep evaluation process. Since humans have a directional acoustic radiation pattern, it is hypothesized that microphone arrays can be used to recognize different body postures, which is highly practical for sleep evaluation applications that already measure respiratory sounds using distant microphones. Furthermore, body posture may have an effect on distant microphone measurement; hence, the measurement can be compensated if the body posture is correctly recognized. A spherical harmonics decomposition approach to the spatial acoustic radiation is presented, assuming an array of eight microphones in a medium-sized audiology booth. The spatial sampling and reconstruction of the radiation pattern is discussed, and a final setup for the microphone array is recommended. A case study is shown using recorded segments of snoring and breathing sounds of three human subjects in three body postures in a silent but not anechoic audiology booth.

Age-related hearing difficulties. I. Hearing impairment, disability, and handicap--a controlled study.

PubMed

Salomon, G; Vesterager, V; Jagd, M

1988-01-01

The study compares the audiological profile of a group of first-time applicants for hearing aids, a group of re-applicants and a group of non-complainers, aged 70-75 years (n = 71). In spite of overlap in range, a significant difference in thresholds and discrimination was found. The lip-reading capacity was well preserved in the elderly, but showed a significant correlation to the general health condition. The audiological benefit of hearing-aids did not increase with early fitting. General satisfaction with life was independent of satisfaction with hearing; two thirds of the patients were satisfied with their aids and used them regularly. The rest were dissatisfied and used them less than once a week. The aids were most systematically used to watch TV. Pure-tone average and handicap scaling were compared as guidelines for hearing-aid fitting. The most powerful tool to identify those in need of hearing-aids was handicap scaling based on interviews concerning self-assessed hearing difficulties.

We verified clinical and psychopedagogic aspects of congenital cases with ocular sequelae, 13 years after toxoplasmosis outbreak in Santa Isabel do Ivaí, and current seroprevalence of this zoonosis in pregnant women. Audiologic and ophthalmologic evaluations were performed in congenital cases, in addition to collection of clinical and psychopedagogic data. In pregnant women, current seroprevalence was observed. Among affected teenagers, 2 of 5 are behind in school grade, and 4 of 5 reported learning difficulties, requiring psychopedagogic monitoring, as well as ocular complaints. We observed predominance of small, scarred, dispersed, type II chorioretinal lesions (hypopigmented halo and hyperpigmented central area), and 1 case of ocular relapse. All patients presented normal audiologic assessment. Among 131 pregnant women, 62 (47.3%) were seronegative and 39 (29.8%) were IgG reactive. Only 1 reported acquiring infection during the outbreak. This is one of the few studies in Brazil showing the outcome of congenital toxoplasmosis, a decade after infection, in one of the world's largest outbreaks.

The International Classification of Functioning, Disability and Health as a Framework for Providing Patient- and Family-Centered Audiological Care for Older Adults and Their Significant Others.

2016-08-01

Hearing impairment is highly prevalent in the older population, and it impacts communication and quality of life for both the people with the hearing difficulties and their significant others. In this article, typical audiological assessment and management of an older adult is contrasted with a best practice approach wherein the World Health Organization's International Classification of Functioning, Disability and Health (ICF) framework is applied. The aim of the comparison is to demonstrate how the ICF expands our focus: rather than merely focusing on impairment, we also consider the activities, participation, and contextual factors for both the person with the hearing impairment and his or her family. A case example of an older patient and her spouse is provided, and their shared experience of the patient's hearing impairment is mapped onto the ICF framework. Family-centered hearing care is recommended for individualizing care and improving outcomes for older patients and their families.

Children referred to audiology services with otherwise unexplained academic, listening, attention, language, or other difficulties are often found to be audiometrically normal. Some of these children receive further evaluation for auditory processing disorder (APD), a controversial construct that assumes neural processing problems within the central auditory nervous system. This study focuses on the evaluation of APD and how it relates to diagnosis in one large pediatric audiology facility. To analyze electronic records of children receiving a central auditory processing evaluation (CAPE) at Cincinnati Children's Hospital, with a broad goal of understanding current practice in APD diagnosis and the test information which impacts that practice. A descriptive, cross-sectional analysis of APD test outcomes in relation to final audiologist diagnosis for 1,113 children aged 5-19 yr receiving a CAPE between 2009 and 2014. Children had a generally high level of performance on the tests used, resulting in marked ceiling effects on about half the tests. Audiologists developed the diagnostic category "Weakness" because of the large number of referred children who clearly had problems, but who did not fulfill the AAA/ASHA criteria for diagnosis of a "Disorder." A "right-ear advantage" was found in all tests for which each ear was tested, irrespective of whether the tests were delivered monaurally or dichotically. However, neither the side nor size of the ear advantage predicted the ultimate diagnosis well. Cooccurrence of CAPE with other learning problems was nearly universal, but neither the number nor the pattern of cooccurring problems was a predictor of APD diagnosis. The diagnostic patterns of individual audiologists were quite consistent. The number of annual assessments decreased dramatically during the study period. A simple diagnosis of APD based on current guidelines is neither realistic, given the current tests used, nor appropriate, as judged by the audiologists providing the service. Methods used to test for APD must recognize that any form of hearing assessment probes both sensory and cognitive processing. Testing must embrace modern methods, including digital test delivery, adaptive testing, referral to normative data, appropriate testing for young children, validated screening questionnaires, and relevant objective (physiological) methods, as appropriate. Audiologists need to collaborate with other specialists to understand more fully the behaviors displayed by children presenting with listening difficulties. To achieve progress, it is essential for clinicians and researchers to work together. As new understanding and methods become available, it will be necessary to sort out together what works and what doesn't work in the clinic, both from a theoretical and a practical perspective.

Children with Auditory Neuropathy Spectrum Disorder Fitted with Hearing Aids Applying the American Academy of Audiology Pediatric Amplification Guideline: Current Practice and Outcomes.

Walker, Elizabeth; McCreery, Ryan; Spratford, Meredith; Roush, Patricia

2016-03-01

Up to 15% of children with permanent hearing loss (HL) have auditory neuropathy spectrum disorder (ANSD), which involves normal outer hair cell function and disordered afferent neural activity in the auditory nerve or brainstem. Given the varying presentations of ANSD in children, there is a need for more evidence-based research on appropriate clinical interventions for this population. This study compared the speech production, speech perception, and language outcomes of children with ANSD, who are hard of hearing, to children with similar degrees of mild-to-moderately severe sensorineural hearing loss (SNHL), all of whom were fitted with bilateral hearing aids (HAs) based on the American Academy of Audiology pediatric amplification guidelines. Speech perception and communication outcomes data were gathered in a prospective accelerated longitudinal design, with entry into the study between six mo and seven yr of age. Three sites were involved in participant recruitment: Boys Town National Research Hospital, the University of North Carolina at Chapel Hill, and the University of Iowa. The sample consisted of 12 children with ANSD and 22 children with SNHL. The groups were matched based on better-ear pure-tone average, better-ear aided speech intelligibility index, gender, maternal education level, and newborn hearing screening result (i.e., pass or refer). Children and their families participated in an initial baseline visit, followed by visits twice a year for children <2 yr of age and once a yr for children >2 yr of age. Paired-sample t-tests were used to compare children with ANSD to children with SNHL. Paired t-tests indicated no significant differences between the ANSD and SNHL groups on language and articulation measures. Children with ANSD displayed functional speech perception skills in quiet. Although the number of participants was too small to conduct statistical analyses for speech perception testing, there appeared to be a trend in which the ANSD group performed more poorly in background noise with HAs, compared to the SNHL group. The American Academy of Audiology Pediatric Amplification Guidelines recommend that children with ANSD receive an HA trial if their behavioral thresholds are sufficiently high enough to impede speech perception at conversational levels. For children with ANSD in the mild-to-severe HL range, the current results support this recommendation, as children with ANSD can achieve functional outcomes similar to peers with SNHL.

Clinical experience with the words-in-noise test on 3430 veterans: comparisons with pure-tone thresholds and word recognition in quiet.

PubMed

Wilson, Richard H

2011-01-01

Since the 1940s, measures of pure-tone sensitivity and speech recognition in quiet have been vital components of the audiologic evaluation. Although early investigators urged that speech recognition in noise also should be a component of the audiologic evaluation, only recently has this suggestion started to become a reality. This report focuses on the Words-in-Noise (WIN) Test, which evaluates word recognition in multitalker babble at seven signal-to-noise ratios and uses the 50% correct point (in dB SNR) calculated with the Spearman-Kärber equation as the primary metric. The WIN was developed and validated in a series of 12 laboratory studies. The current study examined the effectiveness of the WIN materials for measuring the word-recognition performance of patients in a typical clinical setting. To examine the relations among three audiometric measures including pure-tone thresholds, word-recognition performances in quiet, and word-recognition performances in multitalker babble for veterans seeking remediation for their hearing loss. Retrospective, descriptive. The participants were 3430 veterans who for the most part were evaluated consecutively in the Audiology Clinic at the VA Medical Center, Mountain Home, Tennessee. The mean age was 62.3 yr (SD = 12.8 yr). The data were collected in the course of a 60 min routine audiologic evaluation. A history, otoscopy, and aural-acoustic immittance measures also were included in the clinic protocol but were not evaluated in this report. Overall, the 1000-8000 Hz thresholds were significantly lower (better) in the right ear (RE) than in the left ear (LE). There was a direct relation between age and the pure-tone thresholds, with greater change across age in the high frequencies than in the low frequencies. Notched audiograms at 4000 Hz were observed in at least one ear in 41% of the participants with more unilateral than bilateral notches. Normal pure-tone thresholds (≤20 dB HL) were obtained from 6% of the participants. Maximum performance on the Northwestern University Auditory Test No. 6 (NU-6) in quiet was ≥90% correct by 50% of the participants, with an additional 20% performing at ≥80% correct; the RE performed 1-3% better than the LE. Of the 3291 who completed the WIN on both ears, only 7% exhibited normal performance (50% correct point of ≤6 dB SNR). Overall, WIN performance was significantly better in the RE (mean = 13.3 dB SNR) than in the LE (mean = 13.8 dB SNR). Recognition performance on both the NU-6 and the WIN decreased as a function of both pure-tone hearing loss and age. There was a stronger relation between the high-frequency pure-tone average (1000, 2000, and 4000 Hz) and the WIN than between the pure-tone average (500, 1000, and 2000 Hz) and the WIN. The results on the WIN from both the previous laboratory studies and the current clinical study indicate that the WIN is an appropriate clinic instrument to assess word-recognition performance in background noise. Recognition performance on a speech-in-quiet task does not predict performance on a speech-in-noise task, as the two tasks reflect different domains of auditory function. Experience with the WIN indicates that word-in-noise tasks should be considered the "stress test" for auditory function. American Academy of Audiology.

To describe, in terms of functional gain and word recognition, the audiological results of patients under 18 years of age implanted with the active bone conduction implant, Bonebridge™. Retrospective case studies conducted by reviewing the medical records of patients receiving implants between 2014 and 2016 in the public health sector in Chile. All patients implanted with the Bonebridge were included (N = 15). Individuals who had bilateral conductive hearing loss, secondary to external ear malformations, were considered as candidates. The average hearing threshold one month after switch on was 25.2 dB (95%CI 23.5-26.9). Hearing thresholds between 0.5 and 4 kHz were better when compared with bone conduction hearing aids. Best performance was observed at 4 kHz, where improvements to hearing were observed throughout the adaptation process. There was evidence of a significant increase in the recognition of monosyllables. The Bonebridge implant showed improvements to hearing thresholds and word recognition in paediatric patients with congenital conductive hearing loss.

The present humanitarian crisis in Ukraine is putting strains on its healthcare system. This study aimed to assess services and training in otolaryngology, audiology and speech therapy in Ukraine and its geographical neighbours. Survey study of 327 otolaryngologists from 19 countries. Fifty-six otolaryngologists (17 per cent) from 15 countries responded. Numbers of otolaryngologists varied from 3.6 to 12.3 per 100 000 population (Ukraine = 7.8). Numbers of audiologists varied from 0, in Ukraine, to 2.8 per 100 000, in Slovakia, and numbers of speech therapists varied from 0, in Bulgaria, to 4.0 per 100 000, in Slovenia (Ukraine = 0.1). Ukraine lacks newborn and school hearing screening, good availability of otological drills and microscopes, and a cochlear implant programme. There is wide variation in otolaryngology services in Central and Eastern Europe. All countries surveyed had more otolaryngologists per capita than the UK, but availability of audiology and speech and language therapy is poor. Further research on otolaryngology health outcomes in the region will guide service improvement.

To provide guidelines for the development of two types of closed-set speech-perception tests that can be applied and interpreted in the same way across languages. The guidelines cover the digit triplet and the matrix sentence tests that are most commonly used to test speech recognition in noise. They were developed by a working group on Multilingual Speech Tests of the International Collegium of Rehabilitative Audiology (ICRA). The recommendations are based on reviews of existing evaluations of the digit triplet and matrix tests as well as on the research experience of members of the ICRA Working Group. They represent the results of a consensus process. The resulting recommendations deal with: Test design and word selection; Talker characteristics; Audio recording and stimulus preparation; Masking noise; Test administration; and Test validation. By following these guidelines for the development of any new test of this kind, clinicians and researchers working in any language will be able to perform tests whose results can be compared and combined in cross-language studies.

To characterize the findings of behavioral hearing assessment in HIV-positive individuals who received and did not receive antiretroviral treatment. This research was a cross-sectional study. The participants were 45 HIV-positive individuals (18 not exposed and 27 exposed to antiretroviral treatment) and 30 control-group individuals. All subjects completed an audiological evaluation through pure-tone audiometry, speech audiometry, and high-frequency audiometry. The hearing thresholds obtained by pure-tone audiometry were different between groups. The group that had received antiretroviral treatment had higher thresholds for the frequencies ranging from 250 to 3000 Hz compared with the control group and the group not exposed to treatment. In the range of frequencies from 4000 through 8000 Hz, the HIV-positive groups presented with higher thresholds than did the control group. The hearing thresholds determined by high-frequency audiometry were different between groups, with higher thresholds in the HIV-positive groups. HIV-positive individuals presented poorer results in pure-tone and high-frequency audiometry, suggesting impairment of the peripheral auditory pathway. Individuals who received antiretroviral treatment presented poorer results on both tests compared with individuals not exposed to antiretroviral treatment.

Objective The aim of this study was to investigate and compare the auditory findings in vestibular migraine (VM) and migraine patients without a history of vertigo. Methods This study was conducted on 44 patients diagnosed with definite VM and 31 patients diagnosed with migraine who were followed and treated between January 2011 and February 2015. Also, 52 healthy subjects were included in this study as a control group. All participants underwent a detailed otorhinolaryngological examination followed by audiological evaluation, including pure tone audiometry, speech reception threshold, speech recognition score, and acoustic immitancemetry. Results In the VM group, there were 16 patients (36.4%) with tinnitus, while in the other groups we did not observe any patients with tinnitus. The rate of tinnitus in the VM group was significantly higher in comparison to other groups (p<0.05). None of the groups had any patients with permanent or fluctuating sensorineural hearing loss. Conclusion We conclude that patients with VM should be closely and longitudinally followed up for the early detection of other otological symptoms and possible occurrence of sensorineural hearing loss in the long term.

Functional auditory disorders.

Baguley, D M; Cope, T E; McFerran, D J

2016-01-01

There are a number of auditory symptom syndromes that can develop without an organic basis. Some of these, such as nonorganic hearing loss, affect populations similar to those presenting with functional somatosensory and motor symptoms, while others, such as musical hallucination, affect populations with a significantly different demographic and require different treatment strategies. Many of these conditions owe their origin to measurably abnormal peripheral sensory pathology or brain network activity, but their pathological impact is often due, at least in part, to overamplification of the salience of these phenomena. For each syndrome, this chapter briefly outlines a definition, demographics, investigations, putative mechanisms, and treatment strategies. Consideration is given to what extent they can be considered to have a functional basis. Treatments are in many cases pragmatic and rudimentary, needing more work to be done in integrating insights from behavioral and cognitive psychology to auditory neuroscience. The audiology literature has historically equated the term functional with malingering, although this perception is, thankfully, slowly changing. These disorders transcend the disciplines of audiology, otorhinolaryngology, neurology and psychiatry, and a multidisciplinary approach is often rewarding. © 2016 Elsevier B.V. All rights reserved.

To systematically review the relevant peer-review literature investigating the outcome of simulated learning environment (SLE) training in audiology education. A systematic review research design. Fifteen databases were searched with four studies meeting the inclusion criteria. Three of the four studies revealed positive findings for the use of an SLE (that is, the SLE group showed a higher post-training score compared to the traditional training group or a significantly higher post-training score than the non-training groups). One study revealed negative findings where the traditional training group showed a significantly higher post-training score than the SLE group. In addition, both the studies comparing post- and pre-training scores reported significantly higher post-training scores than the pre-training scores of the participants that underwent SLE training. Overall, this review supports the notions that SLE training is an effective learning tool and can be used for basic clinical training. This conclusion should be treated with caution, considering the limited numbers of studies published in this area and future research should be conducted to cope with the gaps highlighted in this review.

The aim of this study is to derive a consensus on an interdisciplinary competency framework regarding a holistic approach for audiological rehabilitation (AR), which includes disciplines from medicine, engineering, social sciences and humanities. We employed a modified Delphi method. In the first round survey, experts were asked to rate an initial list of 28 generic interdisciplinary competencies and to propose specific knowledge areas for AR. In the second round, experts were asked to reconsider their answers in light of the group answers of the first round. An international panel of 27 experts from different disciplines in AR completed the first round. Twenty-two of them completed the second round. We developed a competency framework consisting of 21 generic interdisciplinary competencies grouped in five domains and nine specific competencies (knowledge areas) in three clusters. Suggestions for the implementation of the generic competencies in interdisciplinary programmes were identified. This study reveals insights into the interdisciplinary competencies that are unique for AR. The framework will be useful for educators in developing interdisciplinary programmes as well as for professionals in considering their lifelong training needs in AR.

This study aimed to analyze the perceptions of users of the Brazilian Unified Health System (SUS) about the treatment Center where they were assisted, as well as about the speech-language pathology services rendered by this Center. This is a transversal study composed of an interview with 26 open questions and 14 closed questions applied to 111 individuals who were assisted at the SUS Center in August 2013. The quantitative content analysis was conducted through the use of the GraphPadPrisma 5.1, Statistic Package for Social Sciences (SPSS) 15.0 software and the application of the D'agostino & Person, F-test and chi-squared test. Most participants reported a positive perception about the facilities and staff of the treatment center. They were also positive about the waiting time and the speech-language pathologists' explanations and conduct, especially in the audiology department. Most responses from participants were short and did not present an argumentative context. The treatment center received a high approval rating by most users. The audiology department had better grades than the clinical services related to language and oral motor pathologies.

This work was aimed at establishing the molecular etiology of hearing loss in a 9-year old girl with post-lingual non-syndromic mild sensorineural hearing loss with a complex family history of clinically heterogeneous deafness. The proband's DNA was subjected to NGS analysis of a 59-targeted gene panel, with the use of the Ion Torrent PGM platform. Conventional Sanger sequencing was used for segregation analysis in all the affected relatives. The proband and all the other hearing impaired members of the family underwent a thorough clinical and audiological evaluation. A new likely pathogenic mutation in the EYA4 gene (c.1154C > T; p.Ser385Leu) was identified in the proband and in her 42-year-old father with post-lingual non-syndromic profound sensorineural hearing loss. The EYA4 mutation was also found in the proband's grandfather and uncle, both showing clinical features of Waardenburg syndrome type 1. A novel pathogenic splice-site mutation (c.321+1G > A) of the PAX3 gene was found to co-segregate with the EYA4 mutation in these two subjects. The identified novel EYA4 mutation can be considered responsible of the hearing loss observed in the proband and her father, while a dual molecular diagnosis was reached in the relatives co-segregating the EYA4 and the PAX3 mutations. In these two subjects the DFNA10 phenotype was masked by Waardenburg syndrome. The use of NGS targeted gene-panel, in combination with an extensive clinical and audiological examination led us to identify the genetic cause of the hearing loss in members of a family in which different forms of autosomal dominant deafness segregate. These results provide precise and especially important prognostic and follow-up information for the future audiologic management in the youngest affected member. Copyright © 2017 Elsevier B.V.

2018-06-02

Of late, there has been an increase in hearing impairment cases and to provide the most advantageous solutions to them is an uphill task for audiologists. Significant difficulty faced by the audiologists is in effective programming of hearing aids to provide enhanced satisfaction to the users. The main aim of our study was to develop a software intelligent system (SIS): (i) to perform the required audiological investigations for finding the degree and type of hearing loss, and (ii) to suggest appropriate values of hearing aid parameters for enhancing the speech intelligibility and the satisfaction level among the hearing aid users. In this paper, we present a Neuro-Fuzzy based SIS to automatically predict and suggest the hearing-aid parameters such as gain values, compression ratio and threshold knee point, which are needed to be fixed for different octave frequencies of sound inputs during the hearing-aid trial. The test signals for audiological investigations are generated through the standard hardware present in a personal computer system and with the aid of a software algorithm. The proposed system was validated with 243 subjects' data collected at the Government General Hospital, Chennai, India. The calculated sensitivity, specificity and accuracy of the proposed audiometer incorporated in the SIS were 98.6%, 96.4 and 98.2%, respectively, by comparing its interpretations with those of the 'gold standard' audiometers. Furthermore, 91% (221 of 243) of the hearing impaired subjects attained satisfaction in the first hearing aid trials itself with the gain values as recommended by the improved SIS. The proposed system reduced around 75% of the 'trial and error' time spent by audiologists for enhancing satisfactory usage of the hearing aid. Hence, the proposed SIS could be used to find the degree and type of hearing loss and to recommend hearing aid parameters to provide optimal solutions to the hearing aid users.

Assessing Auditory Processing Deficits in Tinnitus and Hearing Impaired Patients with the Auditory Behavior Questionnaire

PubMed Central

Diges, Isabel; Simón, Francisco; Cobo, Pedro

2017-01-01

Background and Purpose: Auditory processing disorders (APD), tinnitus and hearing loss (HL) are typical issues reported by patients in audiologic clinics. These auditory impairments can be concomitant or mutually excluding. APD are not necessarily accompanied by significant HL, whereas many adults exhibit peripheral HL and typical cognitive deficits often associated with APD. Since HL, tinnitus and APD affects to several parts of the ascending auditory pathway from the periphery to the auditory cortex, there could be some interrelationship between them. For instance, tinnitus has been reported to degrade the auditory localization capacity. Tinnitus is believed to be triggered by deafferentation of normal peripheral input to the central auditory system. This peripheral deficit can be accompanied by HL or not, since a type of permanent cochlear damage (thus deafferentation) without an elevation of hearing thresholds might persist. Therefore, a combined study of APD, tinnitus and HL on the same cohort of patients can be audiologically relevant and worthy. Methods: Statistical analysis is applied to a cohort of 305 patients attending an audiology clinic in Madrid (Spain). This group of patients is first categorized in four subgroups, namely, HLTG (with tinnitus and HL), NHLTG (with tinnitus and without HL), HLNTG (with HL but no tinnitus), and NHLNTG (neither tinnitus nor HL). The statistical variables include Age, Average Auditory Threshold (ATT), for assessing HL, Tinnitus Handicap Inventory (THI), for measuring tinnitus, and a new 25-item Auditory Behavior Questionnaire (ABQ), for scoring APD. Factor analysis is applied to arrange these items into 4 subscales. The internal consistency reliability of this ABQ is confirmed by calculating Cronbach's coefficients α. The test-retest reliability is assessed by the intraclass correlation coefficients, ICC. Statistical techniques applied to the data set include descriptive analysis of variables and Spearman rank correlations (ρ) between them. Results: Overall reliability of ABQ is confirmed by an α value of 0.89 and by an ICC of 0.91. Regarding the internal consistency reliability, the four subscales prove a fairly good consistency with α coefficients above 0.7. Average values of statistical variables show significantly lower age of patients with tinnitus and no HL, which can provide a cue of noise overexposure of this segment of population. These younger patients show also decreased ABQ and similar THI in comparison with patients in the other subgroups. A strong correlation (ρ = 0.63) was found between AAT and Age for the HLNTG subgroup. For the HLTG subgroup, a moderate correlation (ρ = 0.44) was found between ABQ and THI. Conclusion: The utilized questionnaire (ABQ), together with AAT and THI, can help to study comorbid hearing impairments in patients regularly attending an audiological clinic. PMID:28428741

2014-02-01

To review the literature in order to identify outcome measures used in research on adults with hearing loss (HL) as part of the ICF Core Sets development project, and to describe study and population characteristics of the reviewed studies. A systematic review methodology was applied using multiple databases. A comprehensive search was conducted and two search pools were created, pool I and pool II. The study population included adults (≥ 18 years of age) with HL and oral language as the primary mode of communication. 122 studies were included. Outcome measures were distinguished by 'instrument type', and 10 types were identified. In total, 246 (pool I) and 122 (pool II) different measures were identified, and only approximately 20% were extracted twice or more. Most measures were related to speech recognition. Fifty-one different questionnaires were identified. Many studies used small sample sizes, and the sex of participants was not revealed in several studies. The low prevalence of identified measures reflects a lack of consensus regarding the optimal outcome measures to use in audiology. Reflections and discussions are made in relation to small sample sizes and the lack of sex differentiation/descriptions within the included articles.

Auditory adaptation testing as a tool for investigating tinnitus origin: two patients with vestibular schwannoma.

Silverman, Carol A; Silman, Shlomo; Emmer, Michele B

2017-06-01

To enhance the understanding of tinnitus origin by disseminating two case studies of vestibular schwannoma (VS) involving behavioural auditory adaptation testing (AAT). Retrospective case study. Two adults who presented with unilateral, non-pulsatile subjective tinnitus and bilateral normal-hearing sensitivity. At the initial evaluation, the otolaryngologic and audiologic findings were unremarkable, bilaterally. Upon retest, years later, VS was identified. At retest, the tinnitus disappeared in one patient and was slightly attenuated in the other patient. In the former, the results of AAT were positive for left retrocochlear pathology; in the latter, the results were negative for the left ear although a moderate degree of auditory adaptation was present despite bilateral normal-hearing sensitivity. Imaging revealed a small VS in both patients, confirmed surgically. Behavioural AAT in patients with tinnitus furnishes a useful tool for exploring tinnitus origin. Decrease or disappearance of tinnitus in patients with auditory adaptation suggests that the tinnitus generator is the cochlea or the cochlear nerve adjacent to the cochlea. Patients with unilateral tinnitus and bilateral, symmetric, normal-hearing thresholds, absent other audiovestibular symptoms, should be routinely monitored through otolaryngologic and audiologic re-evaluations. Tinnitus decrease or disappearance may constitute a red flag for retrocochlear pathology.

Abstract Objective: To assess patients’ judgements of the effectiveness of the tinnitus and hyperacusis therapies offered in a specialist UK National Health Service audiology department. Design: Cross-sectional service evaluation questionnaire survey. Patients were asked to rank the effectiveness of the treatment they received on a scale from 1 to 5 (1 = no effect, 5 = very effective). Study sample: The questionnaire was sent to all patients who received treatment between January and March 2014 (n = 200) and 92 questionnaires were returned. Results : The mean score was greatest for counselling (Mean = 4.7, SD = 0.6), followed by education (Mean = 4.5, SD = 0.8), cognitive behavioural therapy - CBT (Mean = 4.4, SD = 0.7), and hearing tests (Mean = 4.4, SD = 0.9). Only 6% of responders rated counselling as 3 or below. In contrast, bedside sound generators, hearing aids, and wideband noise generators were rated as 3 or below by 25%, 36%, and 47% of participants, respectively. Conclusion: The most effective components of the tinnitus and hyperacusis therapy interventions were judged by the patients to be counselling, education, and CBT. PMID:27195947

The impact of self-efficacy, expectations, and readiness on hearing aid outcomes.

Ferguson, Melanie A; Woolley, Annie; Munro, Kevin J

2016-07-01

To examine the impact of self-efficacy and expectations for hearing aids, and readiness to improve hearing, on hearing aid outcome measures in first-time adult hearing aid users Design: A prospective, single centre design. Predictor variables measured at the hearing assessment included measures of self-efficacy, expectations and readiness to improve hearing. Outcome measures obtained at six-week follow-up were the Glasgow Hearing Aid Benefit Profile and Satisfaction with Amplification in Daily Life. A sample of 30 first-time adult hearing aid users were recruited through a public-sector funded audiology clinic. When measured prior to hearing aid fitting, self-efficacy for hearing aids predicted satisfaction with hearing aids but was not related to other hearing aid outcomes. Expectations of hearing aids, in particular positive expectations, and readiness to improve hearing predicted outcomes for hearing aid satisfaction and benefit, although not hearing aid use. Hearing sensitivity was not correlated with hearing aid outcomes. These results suggest that assessment of expectations of hearing aids, and readiness to improve hearing, may be useful to help identify individuals attending audiology clinics who would most likely benefit from hearing aid provision.

Decade audiograms were also compared among two groups of affected subjects with different mutations of USH2A. DNA samples from patients with Usher syndrome type II were analysed. The audiological features of patients and affected siblings with USH2A mutations were also examined to identify genotype-phenotype correlations. Genetic and audiometric examinations were performed in 18 subjects from nine families with Usher syndrome type IIA. Three different USH2A mutations were identified in the affected subjects. Both similarities and differences of the auditory phenotype were seen in families with several affected siblings. A variable degree of hearing loss, ranging from mild to profound, was observed among affected subjects. No significant differences in hearing thresholds were found the group of affected subjects with different pathological mutations. Our results indicate that mutations in the USH2A gene and the resulting phenotype are probably modulated by other variables, such as modifying genes, epigenetics or environmental factors which may be of importance for better understanding the etiology of Usher syndrome.

The aim of our study is to reflect hearing impairment of 23children diagnosed with mucopolysaccharidosis (MPS) typeI, II, III and IV. Retrospective study of the clinical, audiological and treatment (medical vs surgical) findings of 23children diagnosed with MPS typeI, II, III or IV followed at a Tertiary Referral Hospital between 1997 and 2015. Six cases of MPSI, 8 of MPSII, 4 of MPSIII and 5 of MPSIV were reviewed. 71.2% of patients had secretory otitis media (SOM) and 54% of patients had some type of hearing loss (HL). The behaviour of hearing loss was variable in each of the subgroups of MPS, finding greater involvement and variability in typesI and II. Children with MPS have a high risk of hearing loss. A significant percentage of transmissive HL progressing to mixed or sensorineural HL was observed. This was more common in typesI and II. Periodic follow up of these patients is mandatory because of hearing impairment and consequences for their development and quality of life.

Otorhinolaryngological problems in medical support of space flights.

1975-01-01

At present the main trends among the most important problems of otorhinolaryngology in space medicine have become defined as vestibulology, audiology and clinical aspects (prophylaxis, diagnosis and treatment of ENT diseases in flight). The principal result of recent vestibular studies has probably been the establishment of an apparent relationship between the resistance of the vestibular system to adequate ground-based stimulation and tolerance to space flight. The findings of the studies formed the basis for the development of a new system of vestibular selection, as well as demonstrated the usefulness of special vestibular training of astronauts by active and passive methods. In audiology certain urgency is acquired by the problem of noise limitation in space cabins and auditory system reliability prediction for preserving a high work capability in crew members. The hemodynamic changes in weightlessness, as well as the possibility for allergic lesions, create conditions for distorted course of the ENT diseases and vaso-motor disorders. The prophylaxis of aspirations also deserves close attention since the possibilities of their onset increase in weightlessness. The rendering of immediate, timely aid will depend not only on the presence of the necessary medical equipment but also on the ability of the crew members to render the appropriate otorhinolaryngological aid.

A multidisciplinary vocational rehabilitation programme, the Vocational Enablement Protocol (VEP) was developed to address the specific needs of employees with hearing difficulties. In the current study we evaluated the process of implementing the VEP in audiologic care among employees with hearing impairment. In conjunction with a randomized controlled trial, we collected and analysed data on seven process parameters: recruitment, reach, fidelity, dose delivered, dose received and implemented, satisfaction, and perceived benefit. Sixty-six employees with hearing impairment participated in the VEP. The multidisciplinary team providing the VEP comprised six professionals. The professionals performed the VEP according to the protocol. Of the recommendations delivered by the professionals, 31% were perceived as implemented by the employees. Compliance rate was highest for hearing-aid uptake (51%). Both employees and professionals were highly satisfied with the VEP. Participants rated good perceived benefit from it. Our results indicate that the VEP could be a useful treatment for employees with hearing difficulties from a process evaluation perspective. Implementation research in the audiological setting should be encouraged in order to further provide insight into parameters facilitating or hindering successful implementation of an intervention and to improve its quality and efficacy.

An Electromechanical Model for the Cochlear Microphonic

NASA Astrophysics Data System (ADS)

Teal, Paul D.; Lineton, Ben; Elliott, Stephen J.

2011-11-01

The first of the many electrical signals generated in the ear, nerves and brain as a response to a sound incident on the ear is the cochlear microphonic (CM). The CM is generated by the hair cells of the cochlea, primarily the outer hairs cells. The potentials of this signal are a nonlinear filtered version of the acoustic pressure at the tympanic membrane. The CM signal has been used very little in recent years for clinical audiology and audiological research. This is because of uncertainty in interpreting the CM signal as a diagnostic measure, and also because of the difficulty of obtaining the signal, which has usually required the use of a transtympanic electrode. There are however, several potential clinical and research applications for acquisition of the CM. To promote understanding of the CM, and potential clinical application, a model is presented which can account for the generation of the cochlear microphonic signal. The model incorporates micro-mechanical and macro-mechanical aspects of previously published models of the basilar membrane and reticular lamina, as well as cochlear fluid mechanics, piezoelectric activity and capacitance of the outer hair cells. It also models the electrical coupling of signals along the scalae.

Initial evaluation of an interactive test of sentence gist recognition.

PubMed

Tye-Murray, N; Witt, S; Castelloe, J

1996-12-01

The laser videodisc-based Sentence Gist Recognition (SGR) test consists of sets of topically related sentences that are cued by short film clips. Clients respond to test items by selecting picture illustrations and may interact with the talker by using repair strategies when they do not recognize a test item. The two experiments, involving 40 and 35 adult subjects, respectively, indicated that the SGR may better predict subjective measures of speechreading and listening performance than more traditional audiologic sentence and nonsense syllable tests. Data from cochlear implant users indicated that the SGR accounted for a greater percentage of the variance for selected items of the Communication Profile for the Hearing-Impaired and the Speechreading Questionnaire for Cochlear-Implant Users than two other audiologic tests. As in previous work, subjects were most apt to ask the talker to repeat an utterance that they did not recognize than to ask the talker to restructure it. It is suggested that the SGR may reflect the interactive nature of conversation and provide a simulated real-world listening and/or speechreading task. The principles underlaying this test are consistent with the development of other computer technologies and concepts, such as compact discinteractive and virtual reality.

The effect of head protection on the hearing of rugby players.

Kieran, S M; Dunne, J; Hughes, J P; Fenton, J E

2008-09-01

Professional rugby players utilise various methods of head protection to prevent against the development of a pinna haematoma. This study tests the hypothesis that these measures, whilst preventing injury, decrease the wearers' hearing threshold and therefore their performance. Eight patients had free field audiometry performed in a soundproof room, with warble tones. All patients were young men (mean 24.75 years (range 22-34)). No participant had ear symptomatology or a past history of ear surgery. Three separate audiological assessments were performed on each patient: normal free field audiometry in a sound field room, following application of adhesive tape and whilst wearing a scrum cap. All measurements were performed by a single audiological scientist. A significant clinical drop in hearing threshold was defined as an increase of 10 dB. No patient demonstrated a significant drop in hearing threshold following the application of either tape or a scrum cap, nor was there a significant difference in the mean (SD) warble tone average: air 7.03 (5.47); tape 7.19 (6.40); scrum cap 6.56 (5.58). Theoretical concerns that "ear taping" and scrum caps affect hearing of rugby players are unfounded and should not discourage their use.

To determine whether the Tinnitus Handicap Inventory (THI), a validated patient-based outcomes measure, may improve our ability to quantify impact and assess therapy for patients with tinnitus. Nonrandomized, prospective analysis of 32 patients undergoing tinnitus retraining therapy (TRT). Assessment tools included comprehensive audiology, a subjective self-assessment survey of tinnitus characteristics, and the THI. Tinnitus Handicap Inventory scores were assessed at baseline and 6 months following TRT. Baseline analysis revealed significant correlation between the subjective presence of hyperacusis and higher total, emotional, and catastrophic THI scores. Tinnitus Handicap Inventory scores correlated with subjective perception of overall tinnitus effect (P<.001). Mean pure-tone threshold average was 17.4 dB, and mean speech discrimination was 97.0%. There were no consistent correlations between baseline audiologic parameters and THI scores. Following 6 months of TRT, the total, emotional, functional, and catastrophic THI scores significantly improved (P<.001). Loudness discomfort levels also significantly improved (P< or =.02). There is significant improvement in self-perceived disability following TRT as measured by the THI. The results confirm the utility of the THI as a patient-based outcomes measure for quantifying treatment status in patients with primary tinnitus.

To assess patients' judgements of the effectiveness of the tinnitus and hyperacusis therapies offered in a specialist UK National Health Service audiology department. Cross-sectional service evaluation questionnaire survey. Patients were asked to rank the effectiveness of the treatment they received on a scale from 1 to 5 (1 = no effect, 5 = very effective). The questionnaire was sent to all patients who received treatment between January and March 2014 (n = 200) and 92 questionnaires were returned. The mean score was greatest for counselling (Mean = 4.7, SD = 0.6), followed by education (Mean = 4.5, SD = 0.8), cognitive behavioural therapy - CBT (Mean = 4.4, SD = 0.7), and hearing tests (Mean = 4.4, SD = 0.9). Only 6% of responders rated counselling as 3 or below. In contrast, bedside sound generators, hearing aids, and wideband noise generators were rated as 3 or below by 25%, 36%, and 47% of participants, respectively. The most effective components of the tinnitus and hyperacusis therapy interventions were judged by the patients to be counselling, education, and CBT.

The baby boomer population will become high users of the health-care system in coming years. Self-report of hearing loss at a primary health-care visit may offer timely referrals to audiological services, but there has been no population-based study of self-reported hearing loss in the baby boomer generation. To determine the clinical value and audiometric correspondence of self-reported hearing loss as a screening tool for the baby boomer population. A population-based study, Busselton Healthy Ageing Study (BHAS), surveying baby boomers born between 1946 and 1964 from the shire of Busselton, Western Australia. A randomized sample of noninstitutionalized baby-boomers listed on the electoral roll (n = 6690) and resident in the shire are eligible to participate. This study reports on data from the first 1004 attendees (53.5% female) with a mean age of 56.23 (SD = 5.43). Data from a self-report question on hearing loss and diagnostic pure tone audiometry was utilized for this study. Analysis included screening performance measures of self-report compared to audiometric cut-offs, receiver operator curve (ROC) to determine optimal level, analysis of variance to compare hearing status to self-report, and binary logistic regression to determine best audiometric predictors. Of the sample, 16% self-reported hearing loss (72.1% males). Logistic regression indicated 4000 Hz as the most important individual frequency related to self-report while the four-frequency average (500, 1000, 2000, and 4000 Hz) >25 dB in the worse ear was the most significant averaged cutoff with 68% sensitivity and 87% specificity. Of those who self-reported a hearing loss, 80% had either a four-frequency average hearing loss >25 dB in the worse ear or a high-frequency average (4000 and 8000 Hz) hearing loss greater than 35 dB in the worse ear. Baby boomer adults who self-report hearing impairment on direct inquiry are most likely to have a hearing loss. A simple question at a primary health care visit may facilitate a timely referral for audiological services in a baby boomer adult, who may be more amenable to rehabilitation.

Military Service Members are often exposed to high levels of occupational noise, solvents, and other exposures that can be damaging to the auditory system. Little is known about hearing loss and how it progresses in Veterans following military service. This epidemiology study is designed to evaluate and monitor a cohort of Veterans for 20 years or more to determine how hearing loss changes over time and how those changes are related to noise exposure and other ototoxic exposures encountered during military service. Data reported here are from baseline assessments of the first 100 study participants (84 males; 16 females; mean age 33.5 years; SD 8.8; range 21-58). Each participant was asked to complete a comprehensive audiologic examination and self-report questionnaires regarding sociodemographic characteristics, noise and solvent exposures, health conditions common among post-deployment Veterans, and the social and emotional consequences of hearing loss. For this relatively young cohort, 29% exhibited hearing loss, defined as average hearing threshold >20 dB HL in the conventional audiometric range. Forty-two percent exhibited hearing loss in the extended-high-frequency audiometric range using the same criterion (average hearing threshold >20 dB HL). Certain factors were found to be associated with poorer hearing in both conventional and extended-high-frequency ranges, including age, type of military branch, years of military service, number of military deployments, noise exposure, tinnitus, and a positive screen for post-traumatic stress disorder. Although the majority of participants had hearing within normal limits, 27% reported a self-perceived mild/moderate hearing handicap and 14% reported a significant handicap. Further research is needed to identify a cause for this discrepancy in audiologic results versus self-report. The information obtained from this longitudinal study could be used in future resource planning with the goal of preventing, as much as possible, the development of hearing loss during military service, and the exacerbation of prevalent hearing loss after military service and over Veterans' lifetimes.

Although audiologists have been using support personnel for over 45 yr, controversy and variability continue with respect to the entry-level education, training methods, and scope of practice. As part of a larger clinical practices survey, this report focuses on use of audiology assistants (AAs) for pediatric settings and "life-span" facilities that had a significant population of pediatric patients. A questionnaire was sent to 116 facilities in geographically diverse locations. Of the 25 surveys returned, 22 had sufficient data to be included for analysis purposes. The majority of respondents assigned duties to AAs as follows: assisting with conditioned play audiometry and visual reinforcement audiometry, infection control, mail management, disposing of protected health information, ordering supplies, calling families, fielding family phone calls, and stocking supplies. In addition, of the nine pediatric facilities that used AAs and reported job duties, the majority assigned troubleshooting equipment and auditory brainstem response (ABR) screening. Two of the five life-span facilities that reported job duties assigned several duties not assigned by any of the pediatric facilities: pure-tone screening, earmold impressions, assisting with videonystagmography and ABR, and in-house hearing aid repairs. Of facilities that use AAs and reported staffing, the ratio of AAs to audiologists ranged from 0.03:1 to 1:0.37, with an average of 0.15 for life-span facilities and 0.17 for the pediatric facilities. Minimum educational levels required were reported as follows: high school (n = 8), college (n = 3), certificate (n = 1), and no requirement (n = 1). Within a small sample size of pediatric and life-span facilities, 14 of 22 centers used AAs to perform a variety of direct patient care, indirect patient care, and clerical duties. Based on the duties recommended within the American Speech-Language-Hearing Association guidelines and by many states, expanded employment of AAs, as well as expansion of assigned duties should be considered. Data are needed to determine the appropriate ratio of AAs to audiologists within different settings and to determine the impact of AAs for accessibility, productivity, and profitability.

Reiss, M; Reiss, G

1999-06-01

Tinnitus rarely can be cured. The patient, however, needs help to avoid countless ineffective treatments and considerable cost. The clinical examination of patients with severe and chronic tinnitus must include associated psychological disturbances. After all medical and audiological treatments have failed, tinnitus patients often are advised to "learn to live with it." The aim of psychosocial treatment is assisting patients in the identification of aggravating factors in tinnitus and teaching them various coping skills.

Current audiological diagnostics

PubMed Central

Hoth, Sebastian; Baljić, Izet

2017-01-01

Today’s audiological functional diagnostics is based on a variety of hearing tests, whose large number takes account of the variety of malfunctions of a complex sensory organ system and the necessity to examine it in a differentiated manner and at any age of life. The objective is to identify nature and origin of the hearing loss and to quantify its extent as far as necessary to dispose of the information needed to initiate the adequate medical (conservative or operational) treatment or the provision with technical hearing aids or prostheses. Moreover, audiometry provides the basis for the assessment of impairment and handicap as well as for the calculation of the degree of disability. In the present overview, the current state of the method inventory available for practical use is described, starting from basic diagnostics over to complex special techniques. The presentation is systematically grouped in subjective procedures, based on psychoacoustic exploration, and objective methods, based on physical measurements: preliminary hearing tests, pure tone threshold, suprathreshold processing of sound intensity, directional hearing, speech understanding in quiet and in noise, dichotic hearing, tympanogram, acoustic reflex, otoacoustic emissions and auditory evoked potentials. Apart from a few still existing gaps, this method inventory covers the whole spectrum of all clinically relevant functional deficits of the auditory system. PMID:29279727

Application of the transtheoretical model of behaviour change for identifying older clients' readiness for hearing rehabilitation during history-taking in audiology appointments.

PubMed

Ekberg, Katie; Grenness, Caitlin; Hickson, Louise

2016-07-01

The transtheoretical model (TTM) of behaviour change focuses on clients' readiness for adopting new health behaviours. This study explores how clients' readiness for change can be identified through their interactions with audiologists during history-taking in initial appointments; and whether clients' readiness has consequences for the rehabilitation decisions they make within the initial appointment. Conversation analysis (CA) was used to examine video-recorded initial audiology appointments with older adults with hearing impairment. The data corpus involved 62 recorded appointments with 26 audiologists and their older adult clients (aged 55+ years). Companions were present in 17 appointments. Clients' readiness for change could be observed through their interaction with the audiologist. Analysis demonstrated that the way clients described their hearing in the history-taking phase had systematic consequences for how they responded to rehabilitation recommendations (in particular, hearing aids) in the management phase of the appointment. In particular, clients identified as being in a pre-contemplation stage-of-change were more likely to display resistance to a recommendation of hearing aids (80% declined). The transtheoretical model of behaviour change can be useful for helping audiologists individualize management planning to be congruent with individual clients' needs, attitudes, desires, and psychological readiness for action in order to optimize clients' hearing outcomes.

Applying the COM-B behaviour model and behaviour change wheel to develop an intervention to improve hearing-aid use in adult auditory rehabilitation.

2016-07-01

To introduce a psychological model of behaviour; the COM-B model and describe how this has been used in combination with the behaviour change wheel (BCW) in developing an intervention which aims to promote regular, long-term use of hearing aids by adults with acquired hearing loss. Qualitative structured interview study using the COM-B model to identify the determinants of behavioural planning on the part of audiologists; a potentially important factor in encouraging long-term hearing-aid use. Ten audiologists drawn from a random sample of five English audiology departments. The analysis suggests that behavioural planning might be more likely to occur if audiologists' psychological capability, physical and social opportunity, and reflective and automatic motivation were addressed. This analysis forms the basis of an intervention design, using the BCW, to encourage behavioural planning by audiologists and subsequent hearing-aid use by people with hearing loss. The COM-B model and BCW can be applied successfully in the context of audiology to analyse the behaviour of both people with hearing loss and professionals working with them, supplying information that is being used in intervention design. The effectiveness of the intervention will be tested in a clinical trial.

2015-07-01

The purpose of this paper was to highlight the importance of cultural influence in understanding hearing-help seeking and hearing-aid uptake. Information on audiological services in different countries and 'theories related to cross-culture' is presented, followed by a general discussion. Twenty-seven relevant literature reviews on hearing impairment, cross-cultural studies, and the health psychology model and others as secondary resources. Despite the adverse consequences of hearing impairment and the significant potential benefits of audiological rehabilitation, only a small number of those with hearing impairment seek professional help and take up appropriate rehabilitation. Therefore, hearing help-seeking and hearing-aid uptake has recently become the hot topic for clinicians and researchers. Previous research has identified many contributing factors for hearing help-seeking with self-reported hearing disability being one of the main factors. Although significant differences in help-seeking and hearing-aid adoption rates have been reported across countries in population studies, limited literature on the influence of cross-cultural factors in this area calls for an immediate need for research. This paper highlights the importance of psychological models and cross-cultural research in the area of hearing help-seeking and hearing-aid uptake, and consequently some directions for future research are proposed.

Audiological data from a population based epidemiological investigation were studied on elderly persons. Specific diagnoses of otological and audiological disorders, which can result in hearing loss, were searched for. A retrospective register study. Three age cohorts, 474 70- and 75-year olds ("younger"), and 252 85-year olds ("older"), were studied. Clinical pure tone and speech audiometry was used. Data from medical files were included. Conductive hearing loss was diagnosed in 6.1% of the "younger" elderly persons, and in 10.3% of the "older" ones. Specific diagnoses (chronic otitis media and otosclerosis) were established in about half of the cases. Sensorineural hearing loss, other than age-related hearing loss and noise induced hearing loss, was diagnosed in 3.4 % and 5.2% respectively. Severely impaired speech recognition, possibly reflecting age-related auditory neuropathy, was found in 0.4% in the "younger" group, and in 10% in the "older" group. Bilateral functional deafness was present in 3.2% of the 85-year-old persons, but was not present in the 70-75-year group. The incidence of probable age-related auditory neuropathy increases considerably from 70-75 to 85 years. There are marked differences between "younger" and "older" elderly persons regarding hearing loss that severely affects oral communication.

An eye-tracking paradigm for analyzing the processing time of sentences with different linguistic complexities.

PubMed

Wendt, Dorothea; Brand, Thomas; Kollmeier, Birger

2014-01-01

An eye-tracking paradigm was developed for use in audiology in order to enable online analysis of the speech comprehension process. This paradigm should be useful in assessing impediments in speech processing. In this paradigm, two scenes, a target picture and a competitor picture, were presented simultaneously with an aurally presented sentence that corresponded to the target picture. At the same time, eye fixations were recorded using an eye-tracking device. The effect of linguistic complexity on language processing time was assessed from eye fixation information by systematically varying linguistic complexity. This was achieved with a sentence corpus containing seven German sentence structures. A novel data analysis method computed the average tendency to fixate the target picture as a function of time during sentence processing. This allowed identification of the point in time at which the participant understood the sentence, referred to as the decision moment. Systematic differences in processing time were observed as a function of linguistic complexity. These differences in processing time may be used to assess the efficiency of cognitive processes involved in resolving linguistic complexity. Thus, the proposed method enables a temporal analysis of the speech comprehension process and has potential applications in speech audiology and psychoacoustics.

An eye-tracking paradigm was developed for use in audiology in order to enable online analysis of the speech comprehension process. This paradigm should be useful in assessing impediments in speech processing. In this paradigm, two scenes, a target picture and a competitor picture, were presented simultaneously with an aurally presented sentence that corresponded to the target picture. At the same time, eye fixations were recorded using an eye-tracking device. The effect of linguistic complexity on language processing time was assessed from eye fixation information by systematically varying linguistic complexity. This was achieved with a sentence corpus containing seven German sentence structures. A novel data analysis method computed the average tendency to fixate the target picture as a function of time during sentence processing. This allowed identification of the point in time at which the participant understood the sentence, referred to as the decision moment. Systematic differences in processing time were observed as a function of linguistic complexity. These differences in processing time may be used to assess the efficiency of cognitive processes involved in resolving linguistic complexity. Thus, the proposed method enables a temporal analysis of the speech comprehension process and has potential applications in speech audiology and psychoacoustics. PMID:24950184

Low-dose administration of Aspartame (Ap) did not produce a significant ototoxic effect at the end of the 6th month. However, duration of the ototoxic effect is shortened and severity of the effect is increased as dose and duration of Ap administration is increased. While Ap toxicity has been studied in short- and long-term studies, its effects on hearing have not been investigated. This study was conducted to evaluate the effects of long-term consumption of Ap administered in various doses on hearing status of rats. The study included 54 female Wistar Albino rats. Ap was given for 6 months to the rats. The groups were assigned according to levels of Ap dosage. DPOAE and ABR tests were utilized for serial hearing evaluations. Serial hearing measurement times were designed as baseline, 1st week, 2nd week, 1st, 2nd, 3rd, and 6th months. While audiological parameters deteriorated with 100 mg/kg/day dose after the 3rd month, ABR thresholds were elevated and DPOAE values were significantly decreased in 500 mg/kg/day and 1000 mg/kg/day applications after the 2nd month. In 2000 mg/kg/day and 4000 mg/kg/day applications, deteriorations in audiological parameters were detected as early as the first and second months; respectively.

Tinnitus is a frequent complaint in patients affected by intracranial hypertension (IH). Recently, some studies have reported an association between idiopathic intracranial hypertension (IIH) and bilateral transverse sinus stenosis (BTSS). We investigated the relationship between BTSS and monosymptomatic tinnitus, regardless of its clinical characteristics, in subjects without clinical evidence of IH. We selected 78 subjects (all women, mean age 49.5 ± 10.36) affected by tinnitus, without clinical history of audiological and otological pathologies, enrolled among outpatients of the Institute of Audiology and Phoniatrics in Catanzaro, Italy, over a 2 year period. All subjects underwent psychometric evaluation, psychoacoustic assessment, neurological and ophthalmological examination, cerebral magnetic resonance venography (MRV) and brain magnetic resonance imaging (MRI). MRV identified BTSS in 17.9% (14 patients). In the BTSS group, tinnitus was bilateral/central in 21%, and monolateral in the remaining patients (50% left; 29% right ear). It was more frequently pulsating in the BTSS group, but 64.9% of BTSS subjects described their tinnitus as stable. No features of tinnitus showed statistical significance in association with BTSS. In BTSS subjects, we found values suggesting IH by lumbar puncture (LP) in 40% of cases. In these patients, LP gave immediate improvement of tinnitus. The association between BTSS and tinnitus, regardless of its features, must be considered when other causes of tinnitus are excluded.

Rationale, aim and objective In 2009, the UK Department of Health formalized recommended National Health Service practices for the management of tinnitus from primary care onwards. It is timely therefore to evaluate the perceived practicality, utility and impact of those guidelines in the context of current practice. Methods We surveyed current practice by posting a 36-item questionnaire to all audiology and hearing therapy staff that we were able to identify as being involved in tinnitus patient care in England. Results In total, 138 out of 351 clinicians responded (39% response rate). The findings indicate a consensus opinion that management should be tailored to individual symptom profiles but that there is little standardization of assessment procedures or tools in use. Conclusions While the lack of standardized practice might provide flexibility to meet local demand, it has drawbacks. It makes it difficult to ascertain key standards of best practice, it complicates the process of clinical audit, it implies unequal patient access to care, and it limits the implementation of translational research outcomes. We recommend that core elements of practice should be standardized, including use of a validated tinnitus questionnaires and an agreed pathway for decision making to better understand the rationale for management strategies offered.

The success of a cochlear implant is dependent on a functioning auditory nerve. An accurate noninvasive method for screening cochlear implant patients to help determine viability of the auditory nerve would allow physicians to better predict the success of the operation. In this study we measured the size of the auditory nerve relative to the size of the juxtaposed facial nerve and correlated these measurements with audiologic test results. The study involved 15 patients, and three normal volunteers. Noninvasive high-resolution bilateral MRI images were acquired from both 1.5T and 3T scanners. The images were reformatted to obtain an anatomically referenced oblique plane perpendicular to the auditory nerve. The cross- sectional areas of the auditory and facial nerves were determined in this plane. Assessment of the data is encouraging. The ratios of auditory to facial nerve size in the control subjects are close to the expected value of 1.0. Patient data ratios range from 0.73 to 1.3, with numbers significantly less than 1.0 suggesting auditory nerve atrophy. The acoustic nerve area correlated to audiologic test findings, particularly (R2equals0.68) to the count of words understood from a list of 100 words. These preliminary analyses suggest that a threshold of size may be determined to differentiate functional from nonfunctional auditory nerves.

Tinnitus as an alarm bell: stress reaction tinnitus model.

PubMed

Alpini, D; Cesarani, A

2006-01-01

Stress is a significant factor influencing the clinical course of tinnitus. Auditory system is particularly sensitive to the effects of different stress factors (chemical, oxidative, emotional, etc.). Different stages of reaction (alarm, resistance, exhaustion) lead to different characteristics of tinnitus and different therapeutic approaches. Individual characteristics of stress reaction may explain different aspects of tinnitus in various patients with different responses to treatment, despite similar audiological and etiological factors. A model based on individual reactions to stress factors (stress reaction tinnitus model) could explain tinnitus as an alarm signal, just like an 'alarm bell', informing the patient that something potentially dangerous for subject homeostasis is happening. Tinnitus could become a disabling symptom when the subject is chronically exposed to a stress factor and is unable to switch off the alarm. Stress signals, specific for each patient, have to be identified during the 'alarm' phase in order to prevent an evolution toward the 'resistance' and 'exhaustion' phases. In these phases, identification of stressor is no more sufficient, due to the organization of a 'paradoxical auditory memory' and a 'pathologically shifted attention to tinnitus'. Identification of stress reaction phase requires accurate otolaryngology and anamnesis combined with audiological matching tests (Feldman Masking Test, for example) and psychometric questionnaires (Tinnitus Reaction and Tinnitus Cognitive Questionnaires).

Owing to technological progress and a growing body of clinical experience, indication criteria for cochlear implants (CI) are being extended to less severe hearing impairments. It is, therefore, worth reconsidering these indication criteria by introducing novel testing procedures. The diagnostic evidence collected will be evaluated. The investigation includes postlingually deafened adults seeking a CI. Prior to surgery, speech perception tests [Freiburg Speech Test and Oldenburg sentence (OLSA) test] were performed unaided and aided using the Oldenburg Master Hearing Aid (MHA) system. Linguistic skills were assessed with the visual Text Reception Threshold (TRT) test, and general state of health, socio-economic status (SES) and subjective hearing were evaluated through questionnaires. After surgery, the speech tests were repeated aided with a CI. To date, 97 complete data sets are available for evaluation. Statistical analyses showed significant correlations between postsurgical speech reception threshold (SRT) measured with the adaptive OLSA test and pre-surgical data such as the TRT test (r=−0.29), SES (r=−0.22) and (if available) aided SRT (r=0.53). The results suggest that new measures and setups such as the TRT test, SES and speech perception with the MHA provide valuable extra information regarding indication for CI. PMID:26557327

Introduction The manipulation of antineoplastic drugs presents high risk for accidents and occupational diseases. Objective To evaluate the auditory and vestibular systems of workers who are exposed to chemotherapeutic treatment in the University Hospital of Universidade Federal de Santa Maria, Brazil, and to identify the use of individual protection equipment, related to the obtained results. Methods This study is a cross-sectional study using a quantitative method. We evaluate 33 male and female workers, ranging from 21–60 years old, of the nursing and pharmacy sectors. The workers underwent conventional Audiologic Assessment; Transient Evoked Otoacoustic Emissions; and Computerized Vectoelectronystagmography. Results The majority of the sample was female (90.9%). Individual protection equipment was used by 90.9% of the workers. Complaints of dizziness were reported by 56.25% of nursing workers and 52.94% of pharmacy workers. Audiological and vestibular assessment results were within normal limits, 96.97% and 74.20%, respectively. However, audiometric configuration of notch type was identified in 75.75% of all workers. Audiometric notches (76%) and altered caloric test (100%) were often associated with decreased use of coal masks. Conclusion Among the workers evaluated, the vestibulocochlear system was within the normal limits. The presence of notch configuration indicates the need to use individual protection equipment.

Binaural Interference: Quo Vadis?

Jerger, James; Silman, Shlomo; Silverman, Carol; Emmer, Michele

2017-04-01

The reality of the phenomenon of binaural interference with speech recognition has been debated for two decades. Research has taken one of two avenues; group studies or case reports. In group studies, a sample of the elderly population is tested on speech recognition under three conditions; binaural, monaural right and monaural left. The aim is to determine the percent of the sample in which the expected outcome (binaural score-better-than-either-monaural score) is reversed (i.e., one of the monaural scores is better than the binaural score). This outcome has been commonly used to define binaural interference. The object of group studies is to answer the "how many" question, what is the prevalence of binaural interference in the sample. In case reports the binaural interference conclusion suggested by the speech recognition tests is not accepted until it has been corroborated by other independent diagnostic audiological measures. The aim is to attempt to determine the basis for the findings, to answer the "why" question. This article is at once tutorial, editorial and a case report. We argue that it is time to accept the reality of the phenomenon of binaural interference, to eschew group statistical approaches in search of an answer to the "how many" question, and to focus on individual case reports in search of an answer to the "why" question.

SUMMARY The latest international guidelines highlight the importance of involving the family in the diagnositic and rehabilitation process of children affected by permanent hearing impairment. This emphasises how meaningful this approach is for the development of the deaf child. So far, there is very little evidence about this approach in Italy, and there are still some barriers to its practical management. The aim of this paper is to report the results of a strategic analysis, which identifies the strengths, weaknesses, opportunities and threats of the family empowerment process during early auditory diagnosis and rehabilitation. The audiology programme should have the goal to offer information and support to families in order to achieve a conscious decision about the use and type of auditory prosthesis and rehabilitation choice within three months after audiologic diagnosis. Within the framework of the Ministry of Health project CCM 2013 "Preventing Communication Disorders: a Regional Program for Early Identification, Intervention and Care of Hearing Impaired Children", a group of professionals identified three main recommendations that can be useful to foster the natural communicative development of the child by strengthening the therapeutic alliance and empowerment of the family. The recommendations obtained with this analysis can help to develop new Italian guidelines with the aim to foster natural communicative development of the child by strengthening the therapeutic alliance and empowerment of the family.

For many adults with dementia, age-related hearing loss is undiagnosed and/or untreated. Untreated hearing loss can exacerbate common dementia-related behavioral symptoms, such as depression, apathy, agitation. Despite the potential benefits to the individual and the family, pursuing and adopting hearing aids for persons with dementia presents with many challenges. As such, this group of vulnerable older adults is well suited for alternative approaches that adopt an interventional audiology framework. This article reviews alternative hearing care models that we have tested when working with older adults with cognitive impairments. We have found that some individuals show improvements in dementia-related problem behaviors and/or in measures of social engagement after brief aural rehabilitation interventions that provide non-custom amplification. We have developed simple training materials to help family and professional caregivers use communication strategies and non-custom amplification. Providing services that can be integrated into the person's broader dementia care has the potential to improve communication and quality of life for individuals and families. There are opportunities in this population to provide basic, simple strategies and make substantial improvements as long as we adopt approaches that bring the services to the people, instead of bringing the people to us in the audiology clinic.

2017-06-13

The purpose of this clinical report is to present case studies of children who are nontraditional candidates for cochlear implantation because they have significant residual hearing in 1 ear and to describe outcomes and considerations for their audiological management and habilitation. Case information is presented for 5 children with profound hearing loss in 1 ear and normal or mild-to-moderate hearing loss in the opposite ear and who have undergone unilateral cochlear implantation. Pre- and postoperative assessments were performed per typical clinic routines with modifications described. Postimplant habilitation was customized for each recipient using a combination of traditional methods, newer technologies, and commercial materials. The 5 children included in this report are consistent users of their cochlear implants and demonstrate speech recognition in the implanted ear when isolated from the better hearing ear. Candidacy criteria for cochlear implantation are evolving. Children with single-sided deafness or asymmetric hearing loss who have traditionally not been considered candidates for cochlear implantation should be evaluated on a case-by-case basis. Audiological management of these recipients is not vastly different compared with children who are traditional cochlear implant recipients. Assessment and habilitation techniques must be modified to isolate the implanted ear to obtain accurate results and to provide meaningful therapeutic intervention.

A Qualitative Case Study of Smartphone-Connected Hearing Aids: Influences on Patients, Clinicians, and Patient-Clinician Interactions.

Innovations in hearing aid technology influence clinicians and individuals who use hearing aids. Little research, to date, explains the innovation adoption experiences and perspectives of clinicians and patients, which matter to a field like audiology, wherein technology innovation is constant. By understanding clinician and patient experiences with such innovations, the field of audiology may develop technologies and ways of practicing in a manner more responsive to patients' needs, and attentive to society's influence. The authors aimed to understand how new innovations influence clinician and patient experiences, through a study focusing on connected hearing aids. "Connected" refers to the wireless functional connection of hearing aids with everyday technologies like mobile phones and tablets. The authors used a qualitative collective case study methodology, borrowing from constructivist grounded theory for data collection and analysis methods. Specifically, the authors designed a collective case study of a connected hearing aid and smartphone application, composed of two cases of experience with the innovation: the case of clinician experiences, and the case of patient experiences. The qualitative sampling methods employed were case sampling, purposive within-case sampling, and theoretical sampling, and culminated in a total collective case n = 19 (clinician case n = 8; patient case n = 11). These data were triangulated with a supplementary sample of ten documents: relevant news and popular media collected during the study time frame. The authors conducted interviews with the patients and clinicians, and analyzed the interview and document data using the constant comparative method. The authors compared their two cases by looking at trends within, between, and across cases. The clinician case highlighted clinicians' heuristic-based candidacy judgments in response to the adoption of the connected hearing aids into their practice. The patient case revealed patients' perceptions of themselves as technologically competent or incompetent, and descriptions of how they learned to use the new technology. Between cases, the study found a difference in the response to how the connected hearing aid changed the clinician-patient relationship. While clinicians valued the increased time they spent "getting to know" their patients, patients experienced some frustration specific to the additional troubleshooting related to Bluetooth connectivity. Across cases, there was a resounding theme of "normalization" of hearing aids via their integration with a "normal" technology (mobile phones) and general lack of concern about privacy in relation to the smartphone application and its tracking and geotagging features. Both audiologists and patients credited the connected hearing aids with increased opportunities to participate more fully in everyday life. The introduction of smartphone-connected hearing aids influenced the identities and candidate profiles of hearing aid users, and the nature of time spent in clinical interactions, in important and interesting ways. The influence of connected hearing aids on patient experience and audiology practice calls for continued research and clinical consideration, with implications for clinical decision-making regarding hearing aid candidacy. Further study should look critically at normalization and possible unintended stigmatizing effects of making hearing aids increasingly discreet. American Academy of Audiology

This case study reports the findings of auditory behavioral and electrophysiological measures performed on a graduate student (identified as LN) presenting verbal disfluency and learning difficulties. Results of behavioral audiological testing documented the presence of auditory processing disorders, particularly temporal processing and binaural integration. Electrophysiological test results, including middle latency, late latency and cognitive potentials, revealed that LN's central auditory system processes acoustic stimuli differently to a reference group with normal hearing.

Utility measures of health-related quality of life in patients treated for benign paroxysmal positional vertigo.

Comparing the effects of different disorders and interventions on health-related quality of life (HRQoL) is important for healthcare policy and accountability. There are two basic approaches to measure HRQoL: questionnaires derived from psychometrics and preference-based measures or utilities derived from econometrics. While disease-specific HRQoL questionnaires, such as the Dizziness Handicap Inventory (DHI), are important because they focus on the impact of a specific problem and its treatments (i.e., vestibular disorders), economic comparisons of the impacts of diseases/disorders and their treatments are typically based on utility assessment. The utility measures for audiology application (UMAA) were developed to measure utilities for various audiologic conditions using a standard computer. The purpose of this study was to determine if the UMAA provides stable, valid, and sensitive utility measures of the effects of benign paroxysmal positional vertigo (BPPV) and its treatment on HRQoL. It was hypothesized that utilities, as measured by the UMAA, would indicate improvement in HRQoL post-treatment for BPPV comparable to a disease-specific health status measure (DHI). The UMAA incorporates three techniques to measure utility: rating scale, standard gamble, and time tradeoff. A utility is a cardinal measure of strength of preference and is measured on a continuum basis from 0.0 (incapacitating dizziness) to 1.0 (no dizziness). Fifty-two adults with BPPV of the posterior semicircular canal completed the UMAA and DHI before treatment and again post-treatment. A subgroup of 15 participants completed the UMAA on two occasions before treatment to assess test-retest stability and to establish critical difference values. Results from this investigation demonstrate that utilities as measured through the UMAA are stable, valid, and comparable to the DHI. Post-treatment utilities were also significantly higher than pretreatment utilities, indicating that the utilities, as measured through the UMAA, are sensitive to improvement in HRQoL after BPPV treatment. Utilities as measured through the UMAA seem sensitive to changes in HRQoL after treatment of BPPV. Since the UMAA can be used to measure patient preference (i.e., utility), it may be useful for comparison of specific audiologic conditions, such as BPPV, to nonaudiologic conditions, such as cardiovascular disease and kidney disease.

Perspectives on the Pure-Tone Audiogram.

PubMed

Musiek, Frank E; Shinn, Jennifer; Chermak, Gail D; Bamiou, Doris-Eva

The pure-tone audiogram, though fundamental to audiology, presents limitations, especially in the case of central auditory involvement. Advances in auditory neuroscience underscore the considerably larger role of the central auditory nervous system (CANS) in hearing and related disorders. Given the availability of behavioral audiological tests and electrophysiological procedures that can provide better insights as to the function of the various components of the auditory system, this perspective piece reviews the limitations of the pure-tone audiogram and notes some of the advantages of other tests and procedures used in tandem with the pure-tone threshold measurement. To review and synthesize the literature regarding the utility and limitations of the pure-tone audiogram in determining dysfunction of peripheral sensory and neural systems, as well as the CANS, and to identify other tests and procedures that can supplement pure-tone thresholds and provide enhanced diagnostic insight, especially regarding problems of the central auditory system. A systematic review and synthesis of the literature. The authors independently searched and reviewed literature (journal articles, book chapters) pertaining to the limitations of the pure-tone audiogram. The pure-tone audiogram provides information as to hearing sensitivity across a selected frequency range. Normal or near-normal pure-tone thresholds sometimes are observed despite cochlear damage. There are a surprising number of patients with acoustic neuromas who have essentially normal pure-tone thresholds. In cases of central deafness, depressed pure-tone thresholds may not accurately reflect the status of the peripheral auditory system. Listening difficulties are seen in the presence of normal pure-tone thresholds. Suprathreshold procedures and a variety of other tests can provide information regarding other and often more central functions of the auditory system. The audiogram is a primary tool for determining type, degree, and configuration of hearing loss; however, it provides the clinician with information regarding only hearing sensitivity, and no information about central auditory processing or the auditory processing of real-world signals (i.e., speech, music). The pure-tone audiogram offers limited insight into functional hearing and should be viewed only as a test of hearing sensitivity. Given the limitations of the pure-tone audiogram, a brief overview is provided of available behavioral tests and electrophysiological procedures that are sensitive to the function and integrity of the central auditory system, which provide better diagnostic and rehabilitative information to the clinician and patient.

Chloral hydrate sedation for auditory brainstem response (ABR) testing in children: Safety and effectiveness.

PubMed

Valenzuela, Dianne G; Kumar, Divjot Singh; Atkins, Cheryl Labelle; Beers, Alison; Kozak, Frederick K; Chadha, Neil K

2016-04-01

The auditory brainstem response (ABR) test is used to identify hearing loss and measure hearing thresholds of infants and children who cannot be tested using standard behavioral hearing testing methods. In order for the ABR to yield useful data, a child must be asleep throughout the duration of the test. In many centers, this is achieved through the use of a general anesthetic, with its inherent risks and costs. Since 2004, ABRs have been routinely conducted at BC Children's Hospital in an ambulatory care setting under oral chloral hydrate sedation, with monitoring by a specialist nurse. The aim of this retrospective study was to assess the effectiveness and safety of nurse-led sedation with chloral hydrate for ABR testing at our tertiary pediatric center. Medical and audiology records were reviewed for children aged 6 months to 17 years who underwent ABR testing from 2004 to 2012. We reviewed the dosage of drug used, condition of the child after chloral hydrate administration, adverse effects, audiological results, patients' vital signs, and the effectiveness of the sedative in keeping the child asleep throughout the duration of the test. Frequency distributions were derived for adverse outcomes. 725 ABR records encompassing 635 children (multiple ABR tests in some children) were reviewed. The average dose of chloral hydrate used was 52mg/kg. The majority of sedated ABR's (80.8%) were completed without any incident. Significant events [apnea and/or bradycardia], minor complications [vomiting, hypoxemia, prolonged sedation, and/or tachypnea] and restlessness were noted in 3.4%, 6.2%, and 5.0% of the cases, respectively. The majority of these issues resolved without medical intervention, such as the need to provide supplementary oxygen. In 95.9% of ABRs, chloral hydrate was successful in sedating the child adequately to answer the audiological question. This forms the largest study to date on oral sedation for ABR testing. Based on our results, the use of chloral hydrate in the presence of a sedation nurse was a safe and reliable method of performing ABR in infants and children. This may be of significant value to centres worldwide exploring alternatives to general anesthesia for ABR testing. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Perceptions Toward Internet-Based Delivery of Hearing Aids among Older Hearing-Impaired Adults.

Despite evidence that hearing aids can improve the social and psychological functioning of older hearing-impaired adults, hearing aid uptake is low. High cost of hearing aids and poor access to audiology services in rural areas are potential barriers to hearing aid acquisition. Methods of hearing aid delivery deviating from the traditional clinician-based model have been available to consumers for many years. One such method is Internet hearing aid sales. However, research exploring Internet-based hearing aid delivery, as a method to improve hearing aid uptake in this population, is limited. The purpose of this study was to explore the perceptions of older hearing aid users (aged ≥65 yr) toward Internet-based hearing aid delivery. A qualitative approach was adopted to investigate older adults' perceptions of buying hearing aids online. The sample consisted of 18 participants aged between 64 and 81 yr. Fourteen men and four women participated in this study. Participants were all experienced hearing aid users. Face-to-face semistructured interviews were conducted. An interview schedule guided the interview. Interviews were recorded with a voice recorder and transcribed verbatim. Thematic analysis of the data was carried out. Seven main themes emerged from the data. A general lack of awareness, but willingness to learn more about Internet hearing aid sales, was found. Two perceived benefits of Internet-based hearing aid delivery were identified: lower cost of hearing aids and greater convenience or physical accessibility. Numerous concerns and limitations were communicated. Concerns regarding the availability of clinical procedures, such as hearing tests, obtaining the correct-sized earmolds, and fine-tuning of hearing aids, were expressed. Participants conveyed distrust in online retailers. However, trust in and a preference for audiologists' expertise, which was not perceived to be available online, was found. Participants further conveyed a preference for face-to-face contact. Finally, in this sample, a general lack of familiarity and confidence in using the Internet was communicated. Internet sales of hearing aids is a controversial topic in audiology. Although Internet-based delivery of hearing aids was perceived by older adults to be potentially beneficial, several shortcomings and concerns were conveyed. Irrespective of opinion of the role of Internet sales, audiologists should consider the opinions of the elderly as to how different service models may improve hearing aid uptake.

Introduction  Communication breakdown, a consequence of hearing impairment (HI), is being fought by fitting amplification devices and providing auditory training since the inception of audiology. The advances in both audiology and rehabilitation programs have led to the advent of computer-based auditory training programs (CBATPs). Objective  To review the existing literature documenting the evidence-based CBATPs for children with HIs. Since there was only one such article, we also chose to review the commercially available CBATPs for children with HI. The strengths and weaknesses of the existing literature were reviewed in order to improve further researches. Data Synthesis  Google Scholar and PubMed databases were searched using various combinations of keywords. The participant, intervention, control, outcome and study design (PICOS) criteria were used for the inclusion of articles. Out of 124 article abstracts reviewed, 5 studies were shortlisted for detailed reading. One among them satisfied all the criteria, and was taken for review. The commercially available programs were chosen based on an extensive search in Google. The reviewed article was well-structured, with appropriate outcomes. The commercially available programs cover many aspects of the auditory training through a wide range of stimuli and activities. Conclusions  There is a dire need for extensive research to be performed in the field of CBATPs to establish their efficacy, also to establish them as evidence-based practices.

Introduction  Communication breakdown, a consequence of hearing impairment (HI), is being fought by fitting amplification devices and providing auditory training since the inception of audiology. The advances in both audiology and rehabilitation programs have led to the advent of computer-based auditory training programs (CBATPs). Objective  To review the existing literature documenting the evidence-based CBATPs for children with HIs. Since there was only one such article, we also chose to review the commercially available CBATPs for children with HI. The strengths and weaknesses of the existing literature were reviewed in order to improve further researches. Data Synthesis  Google Scholar and PubMed databases were searched using various combinations of keywords. The participant, intervention, control, outcome and study design (PICOS) criteria were used for the inclusion of articles. Out of 124 article abstracts reviewed, 5 studies were shortlisted for detailed reading. One among them satisfied all the criteria, and was taken for review. The commercially available programs were chosen based on an extensive search in Google. The reviewed article was well-structured, with appropriate outcomes. The commercially available programs cover many aspects of the auditory training through a wide range of stimuli and activities. Conclusions  There is a dire need for extensive research to be performed in the field of CBATPs to establish their efficacy, also to establish them as evidence-based practices. PMID:29371904

It Is Time to Rethink Central Auditory Processing Disorder Protocols for School-Aged Children.

DeBonis, David A

2015-06-01

The purpose of this article is to review the literature that pertains to ongoing concerns regarding the central auditory processing construct among school-aged children and to assess whether the degree of uncertainty surrounding central auditory processing disorder (CAPD) warrants a change in current protocols. Methodology on this topic included a review of relevant and recent literature through electronic search tools (e.g., ComDisDome, PsycINFO, Medline, and Cochrane databases); published texts; as well as published articles from the Journal of the American Academy of Audiology; the American Journal of Audiology; the Journal of Speech, Language, and Hearing Research; and Language, Speech, and Hearing Services in Schools. This review revealed strong support for the following: (a) Current testing of CAPD is highly influenced by nonauditory factors, including memory, attention, language, and executive function; (b) the lack of agreement regarding the performance criteria for diagnosis is concerning; (c) the contribution of auditory processing abilities to language, reading, and academic and listening abilities, as assessed by current measures, is not significant; and (d) the effectiveness of auditory interventions for improving communication abilities has not been established. Routine use of CAPD test protocols cannot be supported, and strong consideration should be given to redirecting focus on assessing overall listening abilities. Also, intervention needs to be contextualized and functional. A suggested protocol is provided for consideration. All of these issues warrant ongoing research.

Audiologic rehabilitation of individuals with profound unilateral sensorineural hearing loss (USNHL) has traditionally been limited to the use of air-conduction contralateral routing of sound (CROS) hearing aids. Treatment for these individuals has expanded with new applications of the bone-anchored hearing aid (BAHA), transcranial hearing aid (t-CROS), and the cochlear implant. In this article, the authors review the literature that addresses these various treatment options. Contemporary review Historical information is available that describes the limited efficacy of air-conduction CROS hearing aids in lifting hearing handicap associated with USNHL. Current investigations on providing cross hearing are generally focused on use of the BAHA. Little is known at present whether new developments in hearing aid technology can improve on conventional air-conduction CROS or t-CROS approaches. Interestingly, the cochlear implant seems to be a viable option for individuals with USNHL and tinnitus who also have intact auditory nerve pathways. There is indication in the literature that BAHA provides greater relief of hearing handicap associated with USNHL than CROS hearing aids; however, both have been found to provide limited patient satisfaction and seemingly fall short of restoring true sound localization. Adequate trials have not been performed comparing BAHA with the best CROS hearing aid technology. Transcranial hearing aids and cochlear implants are experimental methods to treat USNHL and hold promise, although there remains a lack of studies available to fully support this.

[The Russian-language version of the matrix test (RUMatrix) in free field in patients after cochlear implantation in the long term].

The deterioration of speech intelligibility in the patients using cochlear implantation (CI) systems is especially well apparent in the noisy environment. It explains why phrasal speech tests, such as a Matrix sentence test, have become increasingly more popular in the speech audiometry during rehabilitation after CI. The Matrix test allows to estimate speech perception by the patients in a real life situation. The objective of this study was to assess the effectiveness of audiological rehabilitation of CI patients using the Russian-language version of the matrix test (RUMatrix) in free field in the noisy environment. 33 patients aged from 5 to 40 years with a more than 3 year experience of using cochlear implants inserted at the National Research Center for Audiology and Hearing Rehabilitation were included in our study. Five of these patients were implanted bilaterally. The results of our study showed a statistically significant improvement of speech intelligibility in the noisy environment after the speech processor adjustment; dynamics of the signal-to-noise ratio changes was -1.7 dB (p<0.001). The RUMatrix test is a highly efficient method for the estimation of speech intelligibility in the patients undergoing clinical investigations in the noisy environment. The high degree of comparability of the RUMatrix test with the Matrix tests in other languages makes possible its application in international multicenter studies.

To compare the performance of the Dichotic Sentence Identification (DSI) test in the Brazilian Portuguese version, considering: the right and left ears and the educational status in normal-hearing individuals. This investigation assessed 200 individuals who are normal listeners and right-handed and were divided into seven groups according to the years of schooling. All the participants underwent basic audiologic evaluation and behavioral auditory processing assessment (sound localization test, memory test for verbal and nonverbal sounds in sequence, dichotic digits test, and DSI). The evaluated individuals revealed an average educational status of 13.1 years and results within normal limits in the selected tests for the audiologic and auditory processing assessments. Regarding the DSI test, the educational status showed a dependent relationship with the percentages of correct answers in each stage of the test and the evaluated ear. There was a statistically significant positive correlation between the educational status and the percentage of correct answers for all the stages of the DSI test in both the ears. There was also an effect of the educational level on the results obtained in each condition of the DSI test, with the exception of directed attention to the right ear. Comparing the performance considering the variables studied in the DSI test, we concluded that there is an advantage of the right ear and that, the better the educational level, the better the performance of the individuals.

To assess the prevalence of hyperacusis and severe hyperacusis among children and adolescents seen at an audiology outpatient tinnitus and hyperacusis service. This was a retrospective study. Hyperacusis was considered as present if the average uncomfortable loudness level (ULL) at 0.25, 0.5, 1, 2, 4 and 8 kHz for the ear with the lower average ULL, which is denoted as ULLmin, was ≤77 dB HL. Severe hyperacusis was considered as present if the ULL was 30 dB HL or less for at least one of the measured frequencies for at least one ear. There were 62 young patients with an average age of 12 years (SD = 4.1 years, range 4-18 years). Eighty-five percent of patients had hyperacusis and 17% had severe hyperacusis. On average, ULLs at 8 kHz were 9.3 dB lower than ULLs at 0.25 kHz. For 33% of patients, ULLs were at least 20 dB lower at 8 than at 0.25 kHz. Among children and adolescents seen at an audiology outpatient clinic for tinnitus and hyperacusis, hyperacusis diagnosed on the basis of ULLs is very prevalent and it is often characterised by lower ULLs at 8 than at 0.25 kHz.

McMullan, Alexandra; Kelly-Campbell, Rebecca J; Wise, Kim

2018-03-08

This pilot study aimed to investigate whether revising a hearing aid user guide (HAUG) is associated with improved hearing aid self-efficacy and utility performance. In Part 1, an HAUG was evaluated using the Suitability Assessment of Material (SAM) and readability formulas (Flesch Reading Ease [Flesch, 1943], Flesch-Kincaid Readability Formula [Kincaid, Fishburne, Rogers, & Chissom, 1957], and Simple Measure of Gobbledygook [McLaughlin, 1969]). The HAUG was revised using results from the SAM and best practice guidelines. The revision included generating a video. In Part 2, 30 adults with hearing impairment were randomly assigned to use either the original guide (N = 15) or the revised guide and video (N = 15) to perform a utility task. Participants' self-efficacy was measured using the Basic and Advanced Handling subscales of the Measure of Audiologic Rehabilitation Self-Efficacy for Hearing Aids questionnaire. SAM and readability were compared between the original and revised guides (Doak, Doak, & Root, 1996). SAM and readability were improved following the revision. Participants in the revised guide group performed significantly better on the utility task and on the Measure of Audiologic Rehabilitation Self-Efficacy for Hearing Aids subscales than participants in the original guide group. These results are encouraging as they indicate that there is scope to influence self-efficacy and utility performance through the use of appropriate HAUGs.

In 95 percent of the cases, patients with acoustic neuromas will have some magnitude of hearing loss in the affected ear. This paper reports on four patients who had acoustic neuromas and normal hearing. Results from the case history, audiometric evaluation, auditory brainstem response (ABR), electroneurography (ENOG), and vestibular evaluation are reported for each patient. For all patients, the presence of unilateral tinnitus was the most common complaint. Audiologically, elevated or absent acoustic reflex thresholds and abnormal ABR findings were the most powerful diagnostic tools.

The purpose of this study was to assess the feasibility and effectiveness of live telemedicine applications in hearing amplification and cochlear implantation. A systematic search was performed in PubMed, MEDLINE, PsychINFO, CINALH, and Web of Science to identify peer-reviewed research. Inclusion criteria were titles containing words from the search terms 1) audiology, otolaryngology, and hearing impairment, 2) rehabilitative methods, and 3) telemedicine. Exclusion criteria were: 1) non-English articles, and 2) non-original research. Twelve eligible studies were identified. The studies employed a prospective design in nine of the articles and retrospective case series in three. The use of telemedicine for the provision of cochlear implant services was examined in eight of the articles and with hearing aids in four of the articles. The types of services include intraoperative cochlear implant telemetry; implant programming and assessment of electrode-specific measures and speech recognition after implantation. Hearing aid programming and remote gain assessments were also reported. Many studies assess patient and provider satisfaction along with encounter time comparison. The studies occurred from 2009 to 2014 and took place in seven countries. This review examined the feasibility of remote telemedicine connection to provide in auditory rehabilitation services through hearing aids and cochlear implants. There are significant concerns regarding Internet bandwidth limitations for remote clinics. There is a paucity of research examining reimbursement and cost-effectiveness for services. Further prospective research investigating cost-effectiveness and bandwidth limitations is warranted to assess long-term sustainability of remote audiological rehabilitative service delivery.

Evaluate three standard operational procedures (SOPs), regarding the application of the brainstem auditory evoked potential (BAEP) test, implemented by the Audiology Department of the Center for Studies in Occupational Health and Human Ecology (CESTEH) through the application of a questionnaire and to verify whether the SOPs are effective and assess the necessity for improvement. The study was conducted in three phases: in the first phase, eight speech-language pathologists and seven physicians, with no experience in BAEP, were instructed to read and perform each SOP, eventually all individuals evaluated the SOPs by responding to a questionnaire; in the second phase, the questionnaires were analyzed and the three SOP texts were reviewed; in the third phase, nine speech-language pathologists and six physicians, also with no experience in BAEP, read and re-evaluated the reviewed SOPs through a questionnaire. In the first phase, difficulties in understanding the texts were found, raising doubts about the procedures; however, every participant was able to perform the procedure as a whole. In the third phase, after the review, all individuals were able to perform the procedures appropriately and continuously without any doubts. The assessment of the SOPs by questionnaires showed the need for adaptation in the texts. After the texts were reviewed according to the suggestions of the health professionals, it was possible to observe that the SOPs assisted in the execution of the task, which was conducted without any difficulties or doubts, being regarded effective and ensuring quality to the service offered.

To present diverse symptoms, signs, and findings on diagnostic tests of 11 patients with superior semicircular canal dehiscence (SSCD) syndrome and surgical treatments for dehiscence of 3 patients. Retrospective case review. Tertiary neurotologic and audiologic center. Patients with SSCD documented by history, physical examination, vestibular function testing, and high-resolution computed tomographic scans. Two patients underwent surgical procedures through middle fossa approach, and 1 patient underwent transmastoid repair. The rest underwent conservative treatments. Eleven patients were identified as SSCD. The variety of clinical manifestations, including 1) hearing presentations: mix hearing loss (4 of 11), conductive hearing loss (3 of 11), profound sensorineural hearing loss (2 of 11), and normal hearing (2 of 11); 2) vestibular manifestations: chronic disequilibrium (8 of 11), Tullio phenomenon (7 of 11), Hennebert sign (8 of 11), tinnitus (3 of 11), and autophony (3 of 11); and 3) accompanying disorders: encephalomeningocele (1 of 11). Abnormal nystagmus was identified in 3 patients. Dehiscence of bone overlying superior semicircular canal was confirmed by high-resolution computed tomographic scan in all cases. Three patients underwent operative management. (2 through the middle fossa approach and 1 through a transmastoid repair). Superior semicircular canal dehiscence demonstrates diverse and complex clinical features. Tegmental or petrosal bone rarefaction or mild dehiscences can be a harbinger or an aggressive cause of developing SSCD. No correlation was observed between the size of dehiscence and the severity of vestibular symptoms or the degree of hearing loss. Surgical repair of dehiscence can relieve symptoms with low morbidity.

To explore the characteristics of vestibular evoked myogenic potential (VEMP) in children with enlarged vestibular aqueduct (EVA) and to determine the diagnostic value of VEMP testing for this particular inner ear structural anomaly. Retrospective cohort study in a pediatric tertiary care facility. A total of 25 pediatric cases (37 ears) of EVA were identified with complete records, including otologic evaluation, CT scan of the temporal bone, and audiologic assessment. Results of audiometry, tympanometry, and VEMP testing were analyzed. Hearing loss was found in 97% (36/37) of the ears with EVA. Airbone gaps (conductive components) were found in all hearing losses with normal middle ear pressure and mobility. Abnormally low threshold VEMP responses were found in 92% (34/37) of the ears with EVA. VEMP responses were absent unilaterally in three EVA patients who had vestibular complaints. No clear correlation was found between the size of EVA and the audiologic findings. The presence of airbone gaps in children with EVA was found without apparent middle ear pathology. Characteristics of VEMP in EVA were lower thresholds and higher amplitudes despite of the presence of airbone gaps. The abnormally low threshold VEMP responses suggested a "third" window effect in the pathologic condition of EVA. Unilateral absence of VEMP may implicate peripheral vestibular impairment. The findings from our study are helpful in clinical evaluation of young children who usually give limited and ambiguous input regarding their hearing and vestibular problems.

Mucopolysaccharidosis (MPS) is a lysosomal storage disease caused by deficiency of α-l-iduronidase. The otolaryngological findings include hearing loss, otorrhea, recurrent otitis, hypertrophy of tonsils and adenoid, recurrent rhinosinusitis, speech disorders, snoring, oral breathing and nasal obstruction. To evaluate the impact of enzymatic replacement therapy with laronidase (Aldurazyme(®)) in patients with mucopolysaccharidosis (MPS I), regarding sleep and hearing disorders, and clinical manifestations in the upper respiratory tract (URT). Nine patients with MPS I (8 Hurler-Scheie, and 1 Scheie phenotypes) of both sexes, ages ranging between 3 and 20 years, were included in this study. Patients were evaluated between seven and 11 months before the treatment and between 16 and 22 months after the onset of the enzymatic replacement. They were all submitted to a clinical and otolaryngological evaluation, including nasofibroscopical, polysomnographic and audiologic exams. The results' data showed decreasing of the frequency of ear, nose and throat infections, with improvement of the rhinorrhea and respiratory quality. No remarkable changes were observed regarding macroglossia and tonsil and adenoid hypertrophy. Audiometric and polysomnographic evaluations did not show statistical significance. Enzymatic replacement therapy in patients with mucopolysaccharidosis I provides control of recurrent URT infections, rhinorrhea and respiratory quality, however it is does not seem to improve audiologic and polisomnographic parameters, with no effect on adenoid and tonsils hypertrophy and macroglossia.

The latest international guidelines highlight the importance of involving the family in the diagnostic and rehabilitation process of children affected by permanent hearing impairment. This emphasises how meaningful this approach is for the development of the deaf child. So far, there is very little evidence about this approach in Italy, and there are still some barriers to its practical management. The aim of this paper is to report the results of a strategic analysis, which identifies the strengths, weaknesses, opportunities and threats of the family empowerment process during early auditory diagnosis and rehabilitation. The audiology programme should have the goal to offer information and support to families in order to achieve a conscious decision about the use and type of auditory prosthesis and rehabilitation choice within three months after audiologic diagnosis. Within the framework of the Ministry of Health project CCM 2013 "Preventing Communication Disorders: a Regional Program for Early Identification, Intervention and Care of Hearing Impaired Children", a group of professionals identified three main recommendations that can be useful to foster the natural communicative development of the child by strengthening the therapeutic alliance and empowerment of the family. The recommendations obtained with this analysis can help to develop new Italian guidelines with the aim to foster natural communicative development of the child by strengthening the therapeutic alliance and empowerment of the family. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale.

2018-05-01

To investigate the age effects of cleft palate repair on middle ear function and hearing level in patients who underwent cleft palate repair at different ages by audiologic examination. Medical histories were gathered in detail, and audiologic tests (ie, tympanometry and pure tone hearing threshold) were conducted in 126 patients after palatoplasty. The patients were divided into the following 4 groups according to their ages when they underwent cleft palate repair: group I (0-3 years, 73 patients), group II (4-7 years, 29 patients), group III (8-11 years, 16 patients), and group IV (12 years and older, 8 patients). The data regarding tympanograms, hearing levels, and the average hearing thresholds of each group were analyzed using chi-square tests. The prevalence of middle ear dysfunction and hearing loss in the patients who underwent palatoplasty before 3 years old (27.4% and 2.0% respectively) was significantly lower than that in patients who underwent palatopalsty at 12 years or older (75.0% and 43.7%, respectively). Linear-by-linear association revealed that the prevalences of middle ear dysfunction and hearing loss among the 4 groups were significantly different ( P < .05). The prevalence of middle ear dysfunction and hearing loss tended to increase with advancing age at the time of cleft palate repair. From an audiologist's perspective, palatoplasty at an early age is very beneficial in helping children with cleft palates acquire better middle ear function and hearing level.

Hearing impairment and language delay in infants: Diagnostics and genetics

PubMed Central

Lang-Roth, Ruth

2014-01-01

This overview study provides information on important phoniatric and audiological aspects of early childhood hearing and language development with the aim of presenting diagnostic and therapeutic approaches. The article first addresses the universal newborn hearing screening that has been implemented in Germany for all infants since January 2009. The process of newborn hearing screening from the maternity ward to confirmation diagnostics is presented in accordance with a decision by the Federal Joint Committee (G-BA). The second topic is pediatric audiology diagnostics. Following confirmation of a permanent early childhood hearing disorder, the search for the cause plays an important role. Hereditary hearing disorders and intrauterine cytomegalovirus (CMV) infection, probably the most common cause of an acquired hearing disorder, are discussed and compared with the most common temporary hearing disorder, otitis media with effusion, which in some cases is severe enough to be relevant for hearing and language development and therefore requires treatment. The third topic covered in this article is speech and language development in the first 3 years of life, which is known today to be crucial for later language development and learning to read and write. There is a short overview and introduction to modern terminology, followed by the abnormalities and diagnostics of early speech and language development. Only some aspects of early hearing and language development are addressed here. Important areas such as the indication for a cochlear implant in the first year of life or because of unilateral deafness are not included due to their complexity. PMID:25587365

Surgical repair of the tympanic membrane, termed a type one tympanoplasty is a tried and tested treatment modality. Overlay or underlay technique of tympanoplasty is common. Sandwich tympanoplasty is the combined overlay and underlay grafting of tympanic membrane. To describe and evaluate the modified sandwich graft (mediolateral graft) tympanoplasty using temporalis fascia and areolar fascia. To compare the clinical and audiological outcome of modified sandwich tympanoplasty with underlay tympanoplasty. A total of 88 patients of chronic otitis media were studied. 48 patients (Group A) underwent type one tympanoplasty with modified sandwich graft. Temporalis fascia was underlaid and the areolar fascia was overlaid. 48 patients (Group B) underwent type one tympanoplasty with underlay technique. We assessed the healing and hearing results. Successful graft take up was accomplished in 47 patients (97.9%) in Group A and in 40 patients (83.3%) Group B. The average Air-Bone gap closure achieved in Group A was 24.4±1.7dB while in Group B; it was 22.5±3.5dB. Statistically significant difference was found in graft healing rate. Difference in hearing improvement was not statistically significant. Double layered graft with drum-malleus as a 'meat' of sandwich maintains a perfect balance between sufficient stability and adequate acoustic sensitivity.

Psychometric properties of the self-efficacy for situational communication management questionnaire (SESMQ).

PubMed

Jennings, Mary Beth; Cheesman, Margaret F; Laplante-Lévesque, Ariane

2014-01-01

Perceived self-efficacy (PSE) is one's beliefs in one's capabilities to organize and execute the courses of action required to manage prospective situations. In audiologic rehabilitation, PSE could influence a person with hearing loss' activity limitations, participation restrictions, and response to audiologic rehabilitation. This article reports the psychometric properties of the Self-Efficacy for Situational Communication Management Questionnaire (SESMQ), developed to measure PSE for managing communication in adults with acquired hearing loss. The SESMQ contains 20 situations that are rated on two scales (hearing ability and PSE). Respondents rate how well they can hear from 0 (not well at all) to 10 (very well) and their degree of confidence in managing communication in the situation, or PSE, from 0 (not confident at all) to 10 (very confident). Total scores on each scale can range from 0 to 200, with higher scores indicating greater hearing ability or PSE. Psychometric properties were determined using data collected from The National Centre for Audiology (London, Canada) and the Communication Disability Centre at The University of Queensland (Brisbane, Australia). Participants were 338 adults aged 50 to 93 years with an average high-frequency pure-tone hearing loss in the better ear of 46 dB HL; 157 of the participants owned hearing aids. A two-factor solution was found to be optimal for the SESMQ, with hearing ability accounting for 46.4% of the variation and confidence accounting for 11.6% of the variation in SESMQ scores. Test-retest reliability on a subset of 40 participants resulted in intraclass correlation coefficients of 0.94 for the SESMQ, 0.93 for the hearing ability scale, and 0.94 for the confidence scale, The SESMQ and its scales exhibited high internal consistency, with Cronbach's α of 0.94 for the SESMQ, 0.93 for the hearing ability scale, and 0.94 for the confidence scale. Participants scored lower on the hearing scale items (92.6, SD = 37.1), on average, than on the PSE scale items (123.0, SD = 37.9). SESMQ hearing ability scores were significantly associated with duration of hearing loss, and duration of hearing aid ownership. Only the hearing ability scale of the SESMQ was negatively associated with hearing loss when controlling for age. SESMQ hearing ability and confidence scores were negatively associated with consequences of hearing loss and negative beliefs and attitudes toward hearing loss and its consequences. The results support the SESMQ as an informative measure of PSE specific to communication for adults with hearing loss. The SESMQ may prove useful in both research and clinical practice.

Is gentamicin ototoxic to the fetus?

PubMed

Kirkwood, Allison; Harris, Connie; Timar, Niki; Koren, Gideon

2007-02-01

Gentamicin is used in pregnancy to treat infections that cause complications to the mother and fetus if left untreated. In 2003, Schering, the manufacturer of Garamycin Injectable, amended the product monograph in the Compendium of Pharmaceuticals and Specialties to state that gentamicin should be avoided in pregnancy due to cases of "total irreversible bilateral congenital deafness" in babies exposed to gentamicin in utero. Because we have identified, after an intensive literature search, only two cases over many years of availability, it is questionable whether the outcome can be attributed to drug use rather than other factors. The main objective of this study was to determine whether any infant exposed in utero to intravenous gentamicin and born between January 2002 and April 2006 at Victoria General Hospital demonstrated audiologic deficits on routine hearing testing. Such testing has been universally available since late 2001. Our secondary objectives were to examine patterns of gentamicin use, including indication, dosage, duration, and to determine whether or not monitoring of serum gentamicin levels was done. Women who had received gentamicin were identified through pharmacy records and their charts reviewed for factors that might contribute to fetal deafness including substance abuse, use of other potentially ototoxic medications, genetic predisposition, and intrauterine infections. We reviewed audiology test result and the infants' charts for potential confounding factors, including prematurity, low birth weight, low Apgar scores, anoxia, hyperbilirubinemia, sepsis, and meningitis. Fifty-two charts were reviewed, 40 of which documented live births. There was no case of hearing loss documented. Of the eight fetal losses, six (11.5%) were preterm births before viability, and two were elective terminations. Pyelonephritis was the main indication for gentamicin use (48%), followed by chorioamnionitis (31%) and other miscellaneous indications (21%). Three times daily dosing was used for a mean duration of 2.7 +- 2.3 days, resulting in an average cumulative dose of 764 +- 600 mg gentamicin. The average gestational age at exposure was 28 weeks. Maternal serum gentamicin levels were obtained in 72.5% of cases, and no trough level was above 2 mg/L. Other potentially ototoxic medications were administered to the mother in 17.5% of pregnancies, and to 17.5% of babies in the immediate newborn period. With the exception of one infant who died before additional testing could be carried out, all the infants passed hearing tests, 89% on initial screening. In utero exposure to gentamicin did not cause an increase in audiologic impairment in the infants tested in this cohort.

SUMMARY This report focuses on tuberculous otomastoiditis treated at a third level Italian paediatric hospital. We reviewed the clinical charts of 4077 children who underwent middle ear surgery at the Audiology and Otology Unit of the Institution's ENT Department from January 1995 to December 2011. A tubercular aetiology was identified in 2 cases: a 4-year old boy who presented with primary ear involvement, i.e. with no other infected sites but the middle ear, and a 5-year old girl with secondary tuberculous otomastoidits, who was treated for pulmonary and mediastinal tuberculosis at the age of 7 months.

Clinical Evaluation of Tinnitus.

PubMed

Hertzano, Ronna; Teplitzky, Taylor B; Eisenman, David J

2016-05-01

The clinical evaluation of patients with tinnitus differs based on whether the tinnitus is subjective or objective. Subjective tinnitus is usually associated with a hearing loss, and therefore, the clinical evaluation is focused on an otologic and audiologic evaluation with adjunct imaging/tests as necessary. Objective tinnitus is divided into perception of an abnormal somatosound or abnormal perception of a normal somatosound. The distinction between these categories is usually possible based on a history, physical examination, and audiogram, leading to directed imaging to identify the underlying abnormality.

We describe a case of a 25-year old patient with typical Norrie-Warburg Syndrome. From the first year of his life he was found to be blind, with bilateral sensorineural loss of hearing. Audiological examination showed symmetrical moderate bilateral sensorineural hearing loss. His hearing loss was refractory to treatment for the last eight years. Because of timely diagnosis of hearing loss and timely fitting of a hearing aid, the patient could study at school and graduate from university education. Disease carriers who are clinically healthy can be identified only via chromosome analysis.

Anxiety is found to play an important role in the severity complaint of tinnitus patients. However, when investigating anxiety in tinnitus patients, most studies make use of verbal reports of affect (e.g., self-report questionnaires and/or interviews). These methods reflect conscious appraisals of anxiety, but do not map underlying processing mechanisms. Nonetheless, such mechanisms, like the automatic processing of affective information, are important as they modulate emotional experience and emotion-related behaviour. Research showed that highly anxious people process threatening information (e.g., fearful and angry faces) faster than non-anxious people. Therefore, this study investigates whether tinnitus patients process affective stimuli (happy, sad, fearful, and angry faces) in the same way as highly anxious people do. Our sample consisted out of 67 consecutive tinnitus patients. Relationships between tinnitus severity, pitch, loudness, hearing loss, and the automatic processing of affective information were explored. Results indicate that especially in severely distressed tinnitus patients, the severity complaint is highly related to the automatic processing of fearful (r = 0.37, p < 0.05), angry (r = 0.44, p < 0.00) and happy (r = -0.44, p < 0.00) faces, and these relationships became even stronger after controlling for hearing loss. Furthermore, in contrast with findings on the relation between audiological characteristics (pitch and loudness) and conscious report of anxiety, we did find that the audiological characteristic, loudness, tends to be in some degree related to the automatic processing of fearful faces (r = 0.25, p = 0.08). We conclude that tinnitus is an anxiety-related problem on an automatic processing level.

With advancements in modern medicine and significant improvements in life conditions in the past four decades, the elderly population is rapidly expanding. There is a growing number of those aged 100 years and older. While many changes in the human body occur with physiological aging, as many as 35% to 50% of the population aged 65 to 75 years have presbycusis. Presbycusis is a progressive sensorineural hearing loss that occurs as people get older. There are many studies of the prevalence of age-related hearing loss in the United States, Europe, and Asia. However, no audiological assessment of the population aged 100 years and older has been done. Therefore, it is not clear how well centenarians can hear. We measured middle ear impedance, pure-tone behavioral thresholds, and distortion-product otoacoustic emission from 74 centenarians living in the city of Shaoxing, China, to evaluate their middle and inner ear functions. We show that most centenarian listeners had an "As" type tympanogram, suggesting reduced static compliance of the tympanic membrane. Hearing threshold tests using pure-tone audiometry show that all centenarian subjects had varying degrees of hearing loss. More than 90% suffered from moderate to severe (41 to 80 dB) hearing loss below 2,000 Hz, and profound (>81 dB) hearing loss at 4,000 and 8,000 Hz. Otoacoustic emission, which is generated by the active process of cochlear outer hair cells, was undetectable in the majority of listeners. Our study shows the extent and severity of hearing loss in the centenarian population and represents the first audiological assessment of their middle and inner ear functions.

This study proposed and evaluated a guideline for outcome evaluation for infants and children with hearing loss who wear hearing aids. The University of Western Ontario Pediatric Audiological Monitoring Protocol (UWO PedAMP) was developed following a critical review of pediatric outcome evaluation tools and was systematically examined by the Network of Pediatric Audiologists of Canada. It consists of tools to gather clinical process outcomes as well as functional caregiver reports. The UWO PedAMP was administered to a clinical population of infants and children with hearing aids. Sixty-eight children were administered the functional outcome evaluation tools (i.e., caregiver reports) a total of 133 times. Clinical process outcomes of hearing aid verification (e.g., real-ear-to-coupler difference) revealed typical aided audibility (e.g., Speech Intelligibility Index). Results for the LittlEARS® questionnaire revealed that typically developing children with hearing loss who wear hearing aids are meeting auditory development milestones. Children with mild to moderate comorbidities displayed typical auditory development during the 1st year of life after which development began to decline. Children with complex factors related to hearing aid use had lower scores on the LittlEARS, but auditory development was in parallel to norms. Parents’ Evaluation of Aural/Oral Performance (PEACH) results indicated no age effect on scoring for children above 2 years of age; however, the effect of degree of hearing loss was significant. This work provides clinicians with a systematic, evidence-based outcome evaluation protocol to implement as part of a complete pediatric hearing aid fitting. PMID:22194316

Objective The purpose of this study was to assess the feasibility and effectiveness of live telemedicine applications in hearing amplification and cochlear implantation. Data Sources and Study Selection A systematic search was performed in PubMed, MEDLINE, PsychINFO, CINALH, and Web of Science to identify peer-reviewed research. Inclusion criteria were titles containing words from the search terms (1) audiology, otolaryngology, and hearing impairment, (2) rehabilitative methods, and (3) telemedicine. Exclusion criteria were 1) non-English articles, and 2) non-original research. Data Extraction and Synthesis Twelve eligible studies were identified. The studies employed a prospective design in nine of the articles and retrospective case series in three. The use of telemedicine for the provision of cochlear implant services was examined in eight of the articles and with hearing aids in four of the articles. The types of services include intraoperative cochlear implant telemetry; implant programming and assessment of electrode-specific measures and speech recognition after implantation. Hearing aid programming and remote gain assessments were also reported. Many studies assess patient and provider satisfaction along with encounter time comparison. The studies occurred from 2009–2014 and took place in seven countries. Conclusions This review examined the feasibility of remote telemedicine connection to provide in auditory rehabilitation services through hearing aids and cochlear implants. There are significant concerns regarding Internet bandwidth limitations for remote clinics. There is a paucity of research examining reimbursement and cost-effectiveness for services. Further prospective research investigating cost-effectiveness and bandwidth limitations is warranted to assess long-term sustainability of remote audiological rehabilitative service delivery.

OBJECTIVE: The aim of this study was to characterize the epidemiological profile of the population attending primary health care units in the western region of the city of São Paulo, Brazil, highlighting referred speech-language and hearing complaints. METHOD: This investigation was a cross-sectional observational study conducted in primary health care units. Household surveys were conducted and information was obtained from approximately 2602 individuals, including (but not limited to) data related to education, family income, health issues, access to public services and access to health services. The speech-language and hearing complaints were identified from specific questions. RESULTS: Our results revealed that the populations participating in the survey were heterogeneous in terms of their demographic and economic characteristics. The prevalence of referred speech-language and hearing complaints in this population was 10%, and only half the users of the public health system in the studied region who had complaints were monitored or received specific treatment. CONCLUSIONS: The results demonstrate the importance of using population surveys to identify speech-language and hearing complaints at the level of primary health care. Moreover, these findings highlight the need to reorganize the speech-language pathology and audiology service in the western region of São Paulo, as well as the need to improve the Family Health Strategy in areas that do not have a complete coverage, in order to expand and improve the territorial diagnostics and the speech-language pathology and audiology actions related to the prevention, identification, and rehabilitation of human communication disorders.

Early hearing loss and language abilities in children with Down syndrome.

PubMed

Laws, Glynis; Hall, Amanda

2014-01-01

Although many children with Down syndrome experience hearing loss, there has been little research to investigate its impact on speech and language development. Studies that have investigated the association give inconsistent results. These have often been based on samples where children with the most severe hearing impairments have been excluded and so results do not generalize to the wider population with Down syndrome. Also, measuring children's hearing at the time of a language assessment does not take into account the fluctuating nature of hearing loss in children with Down syndrome or possible effects of losses in their early years. To investigate the impact of early hearing loss on language outcomes for children with Down syndrome. Retrospective audiology clinic records and parent report for 41 children were used to categorize them as either having had hearing difficulties from 2 to 4 years or more normal hearing. Differences between the groups on measures of language expression and comprehension, receptive vocabulary, a narrative task and speech accuracy were investigated. After accounting for the contributions of chronological age and nonverbal mental age to children's scores, there were significant differences between the groups on all measures. Early hearing loss has a significant impact on the speech and language development of children with Down syndrome. Results suggest that speech and language therapy should be provided when children are found to have ongoing hearing difficulties and that joint audiology and speech and language therapy clinics could be considered for preschool children. © 2014 Royal College of Speech and Language Therapists.

A follow-up study was conducted to identify long-term physical and emotional outcomes among Oklahoma City bombing survivors. Baseline data were gathered by the Oklahoma State Department of Health in 1995. Follow-up data were gathered by telephone interviews of survivors from 1-1/2 to 3 years after the bombing. The frequency of medical diagnoses, symptoms, medical cost, physical and social life changes, and services utilized since the bombing were assessed. A total of 494 persons were interviewed, 92 percent had been physically injured in the bombing. Seventy-nine percent of persons interviewed rated their general health status as "good," "very good," or "excellent." Overall, one-fourth to one-third of survivors reported being newly diagnosed with audiologic changes, anxiety, and depression since the bombing. One-third of persons reported preexisting medical conditions that had worsened since the bombing including depression (26%) and asthma/bronchitis (22%). The most frequently reported posttraumatic stress disorder symptoms were "being jumpy or easily startled" and "recurring distressful thoughts of the bombing." The most frequently utilized medical services were psychological counseling (63%) and audiology services (48%). Total costs were estimated of $ 5.7 million. Overall, persons who had been hospitalized with bombing injuries reported higher rates of diagnoses, symptoms, and services utilization. These findings suggest that a large proportion of survivors of a terrorist bombing, especially those seriously injured, will experience long-term physical and/or emotional outcomes and increased need for treatment for bombing-related medical conditions. All survivors should be carefully assessed over time for auditory damage, depression, anxiety, and posttraumatic stress disorder.

Sufficient self-esteem is extremely important for psychosocial functioning. It is hypothesized that hearing-impaired (HI) children have lower levels of self-esteem, because, among other things, they frequently experience lower language and communication skills. Therefore, the aim of this study was to compare HI children's self-esteem across different domains with those of normal hearing (NH) children and to investigate the influence of communication, type of education, and audiological characteristics. This large (N = 252) retrospective, multicenter study consisted of two age- and gender-matched groups: 123 HI children and 129 NH controls (mean age  = 11.8 years). Self-reports were used to measure self-esteem across four domains: perceived social acceptance by peers, perceived parental attention, perceived physical appearance, and global self-esteem. HI children experienced lower levels of self-esteem regarding peers and parents than NH controls. Particularly HI children who attended special education for the deaf were at risk, even after correcting for their language development and intelligence. Yet, levels of global self-esteem and self-esteem involving physical appearance in HI children equalled those of NH controls. Furthermore, younger age at implantation and longer duration of having cochlear implants (CIs) were related to higher levels of self-esteem. HI children experience lower levels of self-esteem in the social domains. Yet, due to the heterogeneity of the HI population, there is high variability in levels of self-esteem. Clinicians must always be aware of the risk and protective factors related to self-esteem in order to help individual patients reach their full potential.

Using Bioacoustical Methodologies to Evaluate Equine Hearing Capabilities and Cognition

NASA Astrophysics Data System (ADS)

Makepeace, Shawn

The field of Bioacoustics is an emerging field of science that investigates various aspects of animal audiology and communication. More recently, audiological means have been used to evaluate the cognitive abilities of animals using event related brain potentials (ERP's). The Mismatch Negativity (MMN) component of the ERP is considered a cognitive neuroelectric phenomenon since it is generated in the area of the cortex that is responsible for evaluating sound stimuli including the ability to discriminate. Such discrimination produces a negative-going waveform with a relative latency of about 150-250 msec when elicited with auditory stimuli in human adults. The MMN response is elicited by use of the oddball paradigm in which two different tones are presented in pseudo-random order. The purpose of this study was to determine if elicitation of the MMN is achievable in the horse by use of current equipment in a non-clinical setting such as a barn. During the course of this experiment, it became obvious that the major challenge was the excessive amount of noise that inundated the waveforms thereby making any specific waves even remotely discernible. Attempts were made to improve the signal-to-noise ratio (SNR) by modifications to the testing unit and the addition of several in-line and digital filters. However, even with these modifications, the MMN response still could not be identifiable within the noise of the waveforms. Therefore, the matter of whether or not the horse elicits a MMN response should be revised to if it is even feasible to elicit a MMN response in these animals.

A self-fitting hearing aid, designed to be assembled and programmed without audiological or computer support, could bring amplification to millions of people in developing countries, who remain unaided due to the lack of a local, professional, audiological infrastructure. The ability to assemble and insert a hearing aid is fundamental to the successful use of a self-fitting device. In this study, the management of such tasks was investigated. Eighty older, urban-dwelling, hearing-impaired adults in a developed country were asked to follow a set of written, illustrated instructions to assemble two slim-fit behind-the-ear hearing aids. Participants were allowed to access assistance with the task from an accompanying partner. A range of personal and audiometric variables was measured through the use of structured questionnaires and standardized tests of health literacy, cognitive function, and manual dexterity. The results showed that 99% of participants were able to complete the hearing aid assembly task, either on their own or with assistance. Health literacy, or the ability to read and understand health-related text, and gender most strongly influenced participants’ ability to complete the assembly task independently and accurately. Higher levels of health literacy were associated with an increased likelihood of independent and successful task completion. Male participants were more likely to complete the task on their own, while female participants were more likely to assemble the device without errors. The results of this study will inform future work regarding development of educational material for the self-fitting hearing aid as well as candidacy for such a device. PMID:22200734

In the last decade, tremendous progress has been made very rapidly in the development of Early Hearing Detection and Intervention (EHDI) systems as a major public health initiative. The percentage of infants screened annually in Spain has increased significantly since the EHDI systems have expanded to all autonomic regions. Historically, high risk indicators have been used for the identification of infants who should receive audiological evaluation but who live in geographic locations where universal hearing screening is not yet available, to help identify infants who pass neonatal screening but are at risk of developing delayed-onset hearing loss and to identify infants who may have passed neonatal screening but have mild forms of permanent hearing loss. In this review, the standard risk factors for hearing loss are analysed and the risk factors known to be associated with late onset or progressive hearing loss are identified. The recommendation for infants with a risk factor that may be considered as low risk is to perform at least one audiology assessment by 24-30 months. In contrast, for an infant with risk factors known to be associated with late onset or progressive hearing loss (such as cytomegalovirus infection or family history), early and more frequent assessment is appropriate. All infants should have an objective standardised screening of global development with a validated assessment tool at 9, 18 and 24-30 months of age or at any time if the health care professional or the family is concerned.

Among the temporal bone abnormalities that can be found in the etiological study of paediatric sensorineural hearing loss (SNHL) by imaging techniques, those related to the internal auditory canal (IAC) are the least frequent. The most prevalent of these abnormalities that is associated with SNHL is stenotic IAC due to its association with cochlear nerve deficiencies. Less frequent and less concomitant with SNHL is the finding of an enlarged IAC (>8mm). Retrospective and descriptive review of clinical associations, imaging, audiological patterns and treatment of 9 children with hearing loss and enlarged IAC in the period 1999 to 2012. Two groups of patients are described. The first, without association with vestibulocochlear dysplasias, consisted of: 2 patients with SNHL without other temporal bone or systemic abnormalities, one with bilateral mixed HL from chromosome 18q deletion, one with a genetic X-linked DFN3 hearing loss, one with unilateral hearing loss in neurofibromatosis type 2 with bilateral acoustic neuroma, and one with unilateral hearing loss with cochlear nerve deficiency. The second group, with association with vestibulocochlear dysplasias, was comprised of: one patient with moderate bilateral mixed hearing loss in branchio-oto-renal syndrome, one with profound unilateral SNHL with recurrent meningitis, and another with profound bilateral SNHL with congenital hypothyroidism. The presence of an enlarged IAC in children can be found in different clinical and audiological settings with relevancies that can range from life-threatening situations, such as recurrent meningitis, to isolated hearing loss with no other associations.

Self-Fitting Hearing Aids

Convery, Elizabeth

2016-01-01

A self-contained, self-fitting hearing aid (SFHA) is a device that enables the user to perform both threshold measurements leading to a prescribed hearing aid setting and fine-tuning, without the need for audiological support or access to other equipment. The SFHA has been proposed as a potential solution to address unmet hearing health care in developing countries and remote locations in the developed world and is considered a means to lower cost and increase uptake of hearing aids in developed countries. This article reviews the status of the SFHA and the evidence for its feasibility and challenges and predicts where it is heading. Devices that can be considered partly or fully self-fitting without audiological support were identified in the direct-to-consumer market. None of these devices are considered self-contained as they require access to other hardware such as a proprietary interface, computer, smartphone, or tablet for manipulation. While there is evidence that self-administered fitting processes can provide valid and reliable results, their success relies on user-friendly device designs and interfaces and easy-to-interpret instructions. Until these issues have been sufficiently addressed, optional assistance with the self-fitting process and on-going use of SFHAs is recommended. Affordability and a sustainable delivery system remain additional challenges for the SFHA in developing countries. Future predictions include a growth in self-fitting products, with most future SFHAs consisting of earpieces that connect wirelessly with a smartphone and providers offering assistance through a telehealth infrastructure, and the integration of SFHAs into the traditional hearing health-care model.

The aim of this study was to evaluate the effectiveness of a vocational enablement protocol (VEP) on need for recovery (NFR) after work as compared with usual care for employees with hearing difficulties. In a randomized controlled trial design, 136 employees with hearing impairment were randomly assigned to either the VEP or the control group. VEP is a multidisciplinary program integrating audiological and occupational care for individuals experiencing difficulties in the workplace due to hearing loss. The primary outcome measure was NFR. Secondary outcome measures were communication strategy subscales (e.g., self-acceptance and maladaptive behavior), distress, and self-efficacy. Data were collected using questionnaires at baseline and at 3, 6, 9, and 12 months follow-up. No significant difference over the complete follow-up period was found between the intervention and control group for NFR. However, we observed a significant difference for one of the secondary outcomes after 12 months. “Self-acceptance” increased significantly in the VEP group, compared with the controls. The mean difference between the two groups was small, being only 0.24 (95% CI [0.04, 0.44]) on a scale of 1 to 5. The results do not support the use of VEP if the aim is to reduce NFR after work at 12 months follow-up. It may be that NFR does not adequately capture what is covered in the VEP. Although marginal, the effect on self-acceptance was significant. This is encouraging given that positive effects on self-acceptance have rarely been shown for audiological rehabilitation programs. Suggestions for further improvement of the VEP are discussed. PMID:29298599

The 'Choose and Book' system provides an online booking service which primary care professionals can book in real time or soon after a patient's consultation. It aims to offer patients choice and improve outpatient clinic attendance rates. An audit comparing attendance rates of new patients booked into the Audiological Medicine Clinic using the 'Choose and Book' system with that of those whose bookings were made through the traditional booking system. Data accrued between 1 April 2008 and 31 October 2008 were retrospectively analysed for new patient attendance at the department, and the age and sex of the patients, method of appointment booking used and attendance record were collected. Patients were grouped according to booking system used - 'Choose and Book' or the traditional system. The mean ages of the groups were compared by a t test. The standard error of the difference between proportions was used to compare the data from the two groups. A P value of < or = 0.05 was considered to be significant. 'Choose and Book' patients had a significantly better rate of attendance than traditional appointment patients, P < 0.01 (95% CI 4.3, 20.5%). There was no significant difference between the two groups in terms of sex, P > 0.1 (95% CI-3.0, 16.2%). The 'Choose and Book' patients, however, were significantly older than the traditional appointment patients, P < 0.001 (95% CI 4.35, 12.95%). This audit suggests that when primary care agents book outpatient clinic appointments online it improves outpatient attendance.

To evaluate the surgical complications, auditory performance, and hearing handicap following cochlear implantation in patients greater than 79 years of age. Retrospective trial, tertiary referral center. The study group was comprised of 21 patients implanted after 79 years of age from 1996 through 2006 with follow-ups past their 8th decade. Pre-op evaluation consisted of pure-tone audiometry and speech discrimination scores (Hearing in Noise Test and City University of New York sentence test). The results of these tests were compared to similar tests taken post-op. A validated hearing handicap questionnaire was used to evaluate the outcome. There were no permanent medical or surgical complications. However, two patients developed exacerbations of previous comorbid conditions (i.e., urinary retention and acute delirium). Implanted patients experienced a significant improvement in audiologic performance, post-op pure tone average, and post-op speech scores (P < .001). A majority of them were able to use the phone and reported that the cochlear implant was of great benefit to them. The post-op hearing handicap inventory for the elderly demonstrated a significant decrease of hearing handicap scores. This is the first study to focus on a patient group this advanced in age. With increasing life expectancy, we should begin to stratify risk versus benefit of cochlear implantation in this age group. Cochlear implantation improved audiologic performance and the quality of life in patients older than 79 years old. There were no permanent medical or surgical complications. Chronic pain and temporary vertigo were the most common complications reported in this elderly group. Laryngoscope, 2009.

Assess the relative efficacy and results of the round window hyaluronic acid pledget depot method for intratympanic gentamicin delivery in Ménière's disease. Retrospective case review. Tertiary referral hospital. Prospective symptomatic and audiologic data were collected on 28 patients undergoing intratympanic gentamicin therapy for Ménière's disease refractory to medical treatment between 2003 and 2009. All patients had the round window membrane exposed via a tympanomeatal flap, and any adhesions were removed. Hyaluronic acid pledgets soaked in 40 mg/ml of gentamicin were then packed into the round window niche and posterior mesotympanum, and the tympanomeatal flap was replaced. Patients audiologic and vertigo symptom outcome scores were recorded at follow-up according to the AAO-HNS 1995 guidelines for reporting results in Ménière's disease. Complete or substantial improvement in vertigo (class A or B) was achieved in 88.5% (23/26) of patients. Hearing loss, defined as greater than 10 dB (PTA average at 0.5, 1, 2, and 4 kHz) was noted in 12 (50%) of 24 patients including 4 patients who had developed "dead ears" (16%). The average hearing loss for all patients excluding the 4 patients with dead ears was 10.7 dB. Round window hyaluronic acid pledget technique used as a sustained delivery vehicle for intratympanic gentamicin treatment for Ménière's disease produces similar rates of vertigo control compared with other techniques but a greater risk of hearing loss. We would recommend the intratympanicinjection titration technique as first line for most patients.

Objective To compare word recognition scores for adults with hearing loss measured using earphones and in the sound field without and with hearing aids (HA) Study design Independent review of pre-surgical audiological data from an active middle ear implant (MEI) FDA clinical trial Setting Multicenter prospective FDA clinical trial Patients Ninety-four adult HA users Interventions/Main outcomes measured Pre-operative earphone, unaided and aided pure tone thresholds, word recognition scores, and speech intelligibility index. Results We performed an independent review of pre-surgical audiological data from a MEI FDA trial and compared unaided and aided word recognition scores with participants’ HAs fit according to the NAL-R algorithm. For 52 participants (55.3%), differences in scores between earphone and aided conditions were >10%; for 33 participants (35.1%), earphone scores were higher by 10% or more than aided scores. These participants had significantly higher pure tone thresholds at 250 Hz, 500 Hz, and 1000 Hz), higher pure tone averages, higher speech recognition thresholds, (and higher earphone speech levels (p=0.002). No significant correlation was observed between word recognition scores measured with earphones and with hearing aids (r=.14; p=0.16), whereas a moderately high positive correlation was observed between unaided and aided word recognition (r=0.68; p<0.001). Conclusion Results of the these analyses do not support the common clinical practice of using word recognition scores measured with earphones to predict aided word recognition or hearing aid benefit. Rather, these results provide evidence supporting the measurement of aided word recognition in patients who are considering hearing aids. PMID:27631832

This report focuses on tuberculous otomastoiditis treated at a third level Italian paediatric hospital. We reviewed the clinical charts of 4077 children who underwent middle ear surgery at the Audiology and Otology Unit of the Institution's ENT Department from January 1995 to December 2011. A tubercular aetiology was identified in 2 cases: a 4-year old boy who presented with primary ear involvement, i.e. with no other infected sites but the middle ear, and a 5-year old girl with secondary tuberculous otomastoidits, who was treated for pulmonary and mediastinal tuberculosis at the age of 7 months.

Velo-pharyngeal dysfunction: Evaluation and management

PubMed Central

Marsh, Jeffrey L.

2009-01-01

Separation of the nasal and oral cavities by dynamic closure of the velo-pharyngeal port is necessary for normal speech and swallowing. Velo-pharyngeal dysfunction (VPD) may either follow repair of a cleft palate or be independent of clefting. While the diagnosis of VPD is made by audiologic perceptual evaluation of speech, identification of the mechanism of the dysfunction requires instrumental visualization of the velo-pharyngeal port during specific speech tasks. Matching the specific intervention for management of VPD with the type of dysfunction, i.e. differential management for differential diagnosis, maximizes the result while minimizing the morbidity of the intervention.

Misophonia is a potentially debilitating condition characterized by increased sensitivity to specific sounds, which cause subsequent behavioral and emotional responses. The nature, clinical phenomenology and etiology of misophonia remain unclear, and misophonic clinical presentations are not currently accounted for by existing psychiatric or audiological disorders. We present a case of pediatric misophonia in the context of comorbid obsessive-compulsive disorder and Tourette's syndrome. Given the interrelationships among obsessive-compulsive spectrum disorders and misophonia, these disorders may share underlying pathophysiology, particularly within the dopaminergic and serotonergic neural systems. Clinical (i.e., treatment) and theoretical implications are discussed. Published by Elsevier Inc.

In this study we present a case of a 71-year-old female patient with sensorineural hearing loss and fitted with bilateral hearing aids. The patient complained of scant benefit from the hearing aid fitting with difficulties in understanding speech with background noise. The otolaryngology examination was normal. Audiological tests revealed bilateral sensorineural hearing loss with threshold values of 51 and 50 dB HL in the right and left ear. The Dichotic Digit Test was administered in a divided attention mode and focalizing the attention to each ear. Results in this test are consistent with a Central Auditory Processing Disorder.

The primary purpose of this study was to test the effect of the combined use of trained standardized parents and a baby simulator on students' hearing screening and parental counseling knowledge and skills. A one-group pretest-posttest quasi-experimental study design was used to assess self-ratings of confidence in knowledge and skills and satisfaction of the educational experience with standardized parents and a baby simulator. The mean age of the 14 audiology students participating in this study was 24.79 years (SD = 1.58). Participants completed a pre- and postevent questionnaire in which they rated their level of confidence for specific knowledge and skills. Six students (2 students in each scenario) volunteered to participate in the infant hearing screening and counseling scenarios, whereas others participated as observers. All participants participated in the briefing and debriefing sessions immediately before and after each of 3 scenarios. After the last scenario, participants were asked to complete a satisfaction survey of their learning experience using simulation and standardized parents. Overall, the pre- and post-simulation event questionnaire revealed a significant improvement in the participants' self-rated confidence levels regarding knowledge and skills. The mean difference between pre- and postevent scores was 0.52 (p < .01). The mean satisfaction level was 4.71 (range = 3.91-5.00; SD = 0.30) based on a Likert scale, where 1 = not satisfied and 5 = very satisfied. The results of this novel educational activity demonstrate the value of using infant hearing screening and parental counseling simulation sessions to enhance student learning. In addition, this study demonstrates the use of simulation and standardized parents as an important pedagogical tool for audiology students. Students experienced a high level of satisfaction with the learning experience.

Is the audiologic status of professional musicians a reflection of the noise exposure in classical orchestral music?

The sound in classical orchestral music is louder than noise emissions allowed by national rules in industry. We wanted to assess the audiologic status of professional musicians at different ages of their careers and to look for a coherence of declined hearing ability and the sound emissions in order to substantiate advices for hearing protection and occupational medicine in musicians. Data from questionnaires (anamnestic data on sound exposure in profession and leisure times, use of hearing protection, self-evaluation of hearing function and hearing deficits), audiometric data and amplitudes of OAE were evaluated from 109 professional musicians aged 30-69 years from three major German orchestras and from 110 students of an academy of music (aged 11-19 years). Sound emissions of the whole orchestra and of single instruments/instrument groups were measured at the orchestra stages and pits during rehearsals and performances. None of the musicians was engaged in noisy hobbies and only a few used hearing protectors regularly. More than 50% of the musicians had a hearing loss of 15 dB(A) and more. Highest losses were found among the strings and the brass players. DPOAE amplitudes coincidently declined with the duration of performing music in the orchestras. Professional musicians aged older than 60 years had a significantly greater hearing loss at 4 and 6 kHz than those aged 30-39 years. Among the strings in one orchestra a dominant hearing deficit in the left ears was observed. Musicians need the same health care for their hearing as workers in noisy industry. A better education on the hearing hazards (use of hearing protectors) as well as sound protection in the rehearsal rooms is necessary. Hearing loss in professional musicians should be accepted as an occupational disease.

The purpose of this study was twofold: (a) to examine extant research in the field of music with premature and full term infants in order to identify protocols being used in the presentation of musical stimuli to neonates and (b) to use knowledge gleaned from audiology as a basis for suggesting a standardized protocol for use of musical stimuli with infants. Articles considered appropriate for inclusion in the analysis met the following criteria: (a) presented data for the effects of music on a dependent measure, (b) had subjects who were identified as either premature or term newborns receiving treatment after birth and prior to discharge from the hospital, and (c) used music for some or all of the aural stimuli. Articles (N = 20) were categorized by demographic information, types of aural stimuli, independent variables, dependent measures, and protocol used to present the musical stimuli. Of primary importance to this study was the protocol used in each study to present musical stimuli. Data regarding total duration of stimuli per day, longest duration of stimuli per day, method of stimuli presentation, placement of speakers, decibel level of stimuli, and where;he decibel level was measured reveal that there is no standard protocol being followed with regard to the presentation of aural stimuli. Recommendations include future research on (a) determining a minimum gestational age where music therapy may be appropriate, (b) determining the frequency spectrum perceived by a premature infant, (c) determining the decibel levels reaching the ear drum and assessing appropriate levels for minimum stimulation with maximum results, and (d) carefully considering the method of stimulus presentation as it will have an impact on the decibel level reaching the ear drum of these infants.

Tinnitus is defined as the conscious perception of a sensation of sound that occurs in the absence of an external stimulus. This audiological symptom affects 7% to 19% of the adult population. The aim of this study is to describe the associated comorbidities present in patients with tinnitus usingjoint and conditional probability analysis. Patients of both genders, diagnosed with unilateral or bilateral tinnitus, aged between 20 and 45 years, and had a full computerised medical record, were selected. Study groups were formed on the basis of the following clinical aspects: 1) audiological findings; 2) vestibular findings; 3) comorbidities such as, temporomandibular dysfunction, tubal dysfunction, otosclerosis and, 4) triggering factors of tinnitus noise exposure, respiratory tract infection, use of ototoxic and/or drugs. Of the patients with tinnitus, 27 (65%) reported hearing loss, 11 (26.19%) temporomandibular dysfunction, and 11 (26.19%) with vestibular disorders. When performing the joint probability analysis, it was found that the probability that a patient with tinnitus having hearing loss was 2742 0.65, and 2042 0.47 for bilateral type. The result for P (A ∩ B)=30%. Bayes' theorem P (AiB) = P(Ai∩B)P(B) was used, and various probabilities were calculated. Therefore, in patients with temporomandibulardysfunction and vestibular disorders, a posterior probability of P (Aі/B)=31.44% was calculated. Consideration should be given to the joint and conditional probability approach as tools for the study of different pathologies. Copyright © 2016 Academia Mexicana de Cirugía A.C.

To analyze the clinical audiological characteristics in Chinese Alport syndrome, and investigate the relationship between the genotypes of Alport syndrome and hearing phenotype. The clinical hearing data of 92 cases diagnosed as Alport syndrome from 2008 August to 2013 August were reviewed and analyzed. All coding exons of COL4A3 and COL4A5 genes were PCR-amplified and sequenced from genomic DNA, or mRNA of COL4A5 gene was RT-PCR-amplified and sequenced from skin fibroblast in 17 cases. Eighty-seven out of 92 cases were found with X-linked dominant inheritance (XLAS); 5 cases with autosomal recessive (ARAS); 44 cases had normal hearing, but 14 young cases had abnormal OAE; 48 cases (52.2%, 35 male, 13 female) had sensorineural hearing loss. A total of 44 cases with XLAS had hearing loss (49.4%), wherein the incidence of hearing impairment was 55.0% in male XLAS, and 37.0% in female XLAS. Mild and moderate hearing loss were found in XLAS. Audiometric curves including groove type (21 cases), descending type (13 cases), flat type (10 cases), high frequency drop type (3 cases) and ascending type (1 case) were found in AS. Sixteen mutations of COL4A3, COL4A5 gene were found in 17 cases with Alport syndrome, including severe mutation in 8 cases with moderate hearing impairment. Mild and moderate hearing impairment, and groove type of audiometric curve are mainly found in Chinese Alport syndrome, which is different from Alport syndrome in western countries. OAE in the early diagnosis of hearing loss is important. Hearing phenotype is related certainly with genotype.

Objective Sufficient self-esteem is extremely important for psychosocial functioning. It is hypothesized that hearing-impaired (HI) children have lower levels of self-esteem, because, among other things, they frequently experience lower language and communication skills. Therefore, the aim of this study was to compare HI children's self-esteem across different domains with those of normal hearing (NH) children and to investigate the influence of communication, type of education, and audiological characteristics. Methods This large (N = 252) retrospective, multicenter study consisted of two age- and gender-matched groups: 123 HI children and 129 NH controls (mean age  = 11.8 years). Self-reports were used to measure self-esteem across four domains: perceived social acceptance by peers, perceived parental attention, perceived physical appearance, and global self-esteem. Results HI children experienced lower levels of self-esteem regarding peers and parents than NH controls. Particularly HI children who attended special education for the deaf were at risk, even after correcting for their language development and intelligence. Yet, levels of global self-esteem and self-esteem involving physical appearance in HI children equalled those of NH controls. Furthermore, younger age at implantation and longer duration of having cochlear implants (CIs) were related to higher levels of self-esteem. Conclusion HI children experience lower levels of self-esteem in the social domains. Yet, due to the heterogeneity of the HI population, there is high variability in levels of self-esteem. Discussion Clinicians must always be aware of the risk and protective factors related to self-esteem in order to help individual patients reach their full potential. PMID:24722329

Our preliminary study showed that the prevalence of hearing loss reported by the wrestlers with cauliflower ear is significantly higher than this rate among wrestlers without cauliflower ear. To the best of our knowledge, no other study has confirmed this finding employing hearing tests. To evaluate and to compare the prevalence of hearing loss among wrestlers with and without cauliflower ears employing hearing tests. The subjects were randomly selected form 14 wrestling clubs in Tehran. Subjects were 201 wrestlers with cauliflower ears (100 wrestlers with one cauliflower ear and 101 wrestlers with two cauliflower ears) and 139 wrestlers without cauliflower ears. All the participants in this study were interviewed to collect information on demographic factors and medical history of risk factors and diseases related to hearing loss. The subjects in both groups underwent otoscopic and audiologic examinations. Audiometric examination results at the frequency range of 0.5 - 8 KHz showed that the prevalence of hearing loss among cauliflower ears was higher than this rate among non-cauliflower ears. Also, the percentage of positive history of ear infections among cauliflower ears (8.4%) was about two times more than this finding among non-cauliflower ears (4.9%). This difference tended to be significant (OR: 1.86, P = 0.06, 95% CI: 0.98 - 3.53). To the best of our knowledge, this is the first study showing that the prevalence of hearing loss among cauliflower ears is higher than this rate among non-cauliflower ears confirmed by audiological tests. This emphasizes that, more preventive measures such as mandatory ear gear for wrestlers are required.

Factors influencing tests of auditory processing: a perspective on current issues and relevant concerns.

Cacace, Anthony T; McFarland, Dennis J

Tests of auditory perception, such as those used in the assessment of central auditory processing disorders ([C]APDs), represent a domain in audiological assessment where measurement of this theoretical construct is often confounded by nonauditory abilities due to methodological shortcomings. These confounds include the effects of cognitive variables such as memory and attention and suboptimal testing paradigms, including the use of verbal reproduction as a form of response selection. We argue that these factors need to be controlled more carefully and/or modified so that their impact on tests of auditory and visual perception is only minimal. To advocate for a stronger theoretical framework than currently exists and to suggest better methodological strategies to improve assessment of auditory processing disorders (APDs). Emphasis is placed on adaptive forced-choice psychophysical methods and the use of matched tasks in multiple sensory modalities to achieve these goals. Together, this approach has potential to improve the construct validity of the diagnosis, enhance and develop theory, and evolve into a preferred method of testing. Examination of methods commonly used in studies of APDs. Where possible, currently used methodology is compared to contemporary psychophysical methods that emphasize computer-controlled forced-choice paradigms. In many cases, the procedures used in studies of APD introduce confounding factors that could be minimized if computer-controlled forced-choice psychophysical methods were utilized. Ambiguities of interpretation, indeterminate diagnoses, and unwanted confounds can be avoided by minimizing memory and attentional demands on the input end and precluding the use of response-selection strategies that use complex motor processes on the output end. Advocated are the use of computer-controlled forced-choice psychophysical paradigms in combination with matched tasks in multiple sensory modalities to enhance the prospect of obtaining a valid diagnosis.

Auditory training and challenges associated with participation and compliance.

PubMed

Sweetow, Robert W; Sabes, Jennifer Henderson

2010-10-01

When individuals have hearing loss, physiological changes in their brain interact with relearning of sound patterns. Some individuals utilize compensatory strategies that may result in successful hearing aid use. Others, however, are not so fortunate. Modern hearing aids can provide audibility but may not rectify spectral and temporal resolution, susceptibility to noise interference, or degradation of cognitive skills, such as declining auditory memory and slower speed of processing associated with aging. Frequently, these deficits are not identified during a typical "hearing aid evaluation." Aural rehabilitation has long been advocated to enhance communication but has not been considered time or cost-effective. Home-based, interactive adaptive computer therapy programs are available that are designed to engage the adult hearing-impaired listener in the hearing aid fitting process, provide listening strategies, build confidence, and address cognitive changes. Despite the availability of these programs, many patients and professionals are reluctant to engage in and complete therapy. The purposes of this article are to discuss the need for identifying auditory and nonauditory factors that may adversely affect the overall audiological rehabilitation process, to discuss important features that should be incorporated into training, and to examine reasons for the lack of compliance with therapeutic options. Possible solutions to maximizing compliance are explored. Only a small portion of audiologists (fewer than 10%) offer auditory training to patients with hearing impairment, even though auditory training appears to lower the rate of hearing aid returns for credit. Patients to whom auditory training programs are recommended often do not complete the training, however. Compliance for a cohort of home-based auditory therapy trainees was less than 30%. Activities to increase patient compliance to auditory training protocols are proposed. American Academy of Audiology.

Although insulin-like growth factor 1 (IGF-1) has been shown to be important for inner-ear development in animal models, little is known about the otologic and audiologic findings of children with growth hormone deficiency (GHD). The goal of this study is to evaluate the prevalence, type, and severity of hearing impairment in children with GHD. Audiologic, otologic, and demographic data were recorded for children with a diagnosis of GHD in the AudGen database. Data for each patient were selected based on the first encounter with available complete audiometric data or the first encounter with a type of hearing loss documented. The patients were then stratified by type and severity of hearing loss, and otologic issues were documented. A separate cohort comprised of children with GHD without hearing loss was compared as a control. 209 children with GHD met inclusion criteria. 173 (83%) of these patients had hearing loss. 79% of losses were bilateral and 21% were unilateral (309 total ears with hearing loss). 293 of the 309 ears with hearing loss had audiograms with ear-specific thresholds; 47 had conductive, 24 had sensorineural, 65 had mixed and 157 had undefined hearing loss with incomplete audiograms. Pure-tone averages (PTA) were higher among patients with mixed hearing loss compared to patients with all other loss types. Hearing loss is prevalent in children with GHD with a predisposition to be bilateral. These findings suggest the need for increased awareness and routine hearing screening for patients with GHD. Further studies may elucidate the etiology of the hearing impairment in children with GHD to better aid pediatricians, endocrinologists, otolaryngologists and audiologists when assessing and managing these children.

2017-12-01

The aim of this article is to determine hearing and mortality outcomes following temporal bone fractures. Retrospective chart review was performed of 152 patients diagnosed with a temporal bone fracture presenting to the emergency room at a tertiary care referral center over a 10-year period. Utilizing Patients' previously obtained temporal bone computed tomographic scans and audiograms, fractures were classified based on several classification schemes. Correlations between fracture patterns, mortality, and hearing outcomes were analyzed using χ 2 tests. Ossicular chain disruption was seen in 11.8% of patients, and otic capsule violation was seen in 5.9%; 22.7% of patients presented for audiologic follow-up. Seventeen patients with conductive hearing loss had air-bone gaps of 26 ± 7.5 dB (500 Hz), 27 ± 6.8 dB (1,000 Hz), 18 ± 6.2 dB (2,000 Hz), and 32 ± 7.7 dB (4,000 Hz). Two cases of profound sensorineural hearing loss were associated with otic capsule violation. No fracture classification scheme was predictive of hearing loss, although longitudinal fractures were statistically associated with ossicular chain disruption ( p  < 0.01). Temporal bone fractures in patients older than 60 years carried a relative risk of death of 3.15 compared with those younger than 60 years. The average magnitude of conductive hearing loss resulting from temporal bone fracture ranged from 18 to 32 dB in this cohort. Classification of fracture type was not predictive of hearing loss, despite the statistical association between ossicular chain disruption and longitudinal fractures. This finding may be due to the low follow-up rates of this patient population. Physicians should make a concerted effort to ensure that audiological monitoring is executed to prevent and manage long-term hearing impairment.

Our study aimed to objectively describe the audiological characteristics of wheeze and crackles in children by using digital stethoscope (DS) auscultation, as well as assess concordance between standard auscultation and two different DS devices in their ability to detect pathological breath sounds. Twenty children were auscultated by a paediatric consultant doctor and digitally recorded using the Littman™ 3200 Digital Electronic Stethoscope and a Clinicloud™ DS with smart device. Using spectrographic analysis, we found those with clinically described wheeze had prominent periodic waveform segments spanning expiration for a period of 0.03-1.2 s at frequencies of 100-1050 Hz, and occasionally spanning shorter inspiratory segments; paediatric crackles were brief discontinuous sounds with a distinguishing waveform. There was moderate concordance with respect to wheeze detection between digital and standard binaural stethoscopes, and 100% concordance for crackle detection. Importantly, DS devices were more sensitive than clinician auscultation in detecting wheeze in our study. Objective definition of audio characteristics of abnormal paediatric breath sounds was achieved using DS technology. We demonstrated superiority of our DS method compared to traditional auscultation for detection of wheeze. What is Known: • The audiological characteristics of abnormal breath sounds have been well-described in adult populations but not in children. • Inter-observer agreement for detection of pathological breath sounds using standard auscultation has been shown to be poor, but the clinical value of now easily available digital stethoscopes has not been sufficiently examined. What is New: • Digital stethoscopes can objectively define the nature of pathological breath sounds such as wheeze and crackles in children. • Paediatric wheeze was better detected by digital stethoscopes than by standard auscultation performed by an expert paediatric clinician.

Position Paper of the German Society of Oto-Rhino-Laryngology, Head and Neck Surgery and the German Society of Phoniatrics and Pediatric Audiology - Current State of Clinical and Endoscopic Diagnostics, Evaluation, and Therapy of Swallowing Disorders in Children and AdultsSwallowing disorders are frequent. The main concern is mortality due to aspiration induced pneumonia and malnutrition. On the other hand quality of life is severely affected. The demographic trend indicates an increase of dysphagia in the future. Neurodegenerative diseases, tumors of the digestive tract and sequelae of tumor treatment in the head and neck region are the main pathologic entities.Predominantly ENT physicians and phoniatrists, are asked for diagnostics and therapy who will coordinate the interdisciplinary treatment according to the endoscopic findings.A differentiated approach in history, diagnostics, and symptom oriented treatment is necessary for the mostly complex disorders. The integration of non-medical personnel such as logopeds (speech language pathologists), physiotherapists, and occupational therapists in planning and executing an effective therapy expands and completes the patient-oriented care. Conservative treatment by these therapists is an important pillar in the treatment. Parts of the specific diagnostics can be taken over by them in close cooperation.In particular an interdisciplinary cooperation with the staff from intensive care medicine is indispensable.The diagnostic procedures of specific endoscopy as described in this position paper are part of the primary and fundamental tasks of ENT specialists and phoniatrists.Endoscopy is a medical service that is basically not delegable. Consequently substitution of the physician is precluded. © Georg Thieme Verlag KG Stuttgart · New York.

Application of Transtheoretical (Stages of Change) Model in Studying Attitudes and Behaviors of Adults with Hearing Loss: A Descriptive Review.

Manchaiah, Vinaya; Hernandez, Barbara Michiels; Beck, Douglas L

Health Behavior Change (HBC) refers to facilitating changes to habits and/or behaviors related to health. There are a number of models/theories of HBC, which provide a structured framework to better understand the HBCs of individuals. The Transtheoretical Model (TTM, aka "the Stages of Change" model) is an integrative model used to conceptualize the process of intentional behavior change and is applied to a variety of behaviors, populations, and settings. In the last few years, use of TTM by the profession of audiology has been increasing. This descriptive literature review was aimed at identifying and presenting a summary of research studies, which use TTM to study the attitudes and behaviors of adults with hearing loss. A literature review was conducted. This review included 13 empirical studies. A literature review was conducted using the EBSCOhost and included the databases Cumulative Index to Nursing and Allied Health, MEDLINE, and PsycINFO. The review suggests TTM is useful in studying the attitudes and behaviors of adults with hearing loss. There are positive associations between stages of change and help-seeking, intervention uptake, and hearing rehabilitation outcome (i.e., benefit and satisfaction). However, associations with intervention decisions and intervention use were not evident. It appears help-seeking, intervention uptake, and successful outcomes are usually displayed in people in the later stages of change as those with greater hearing loss are often in the later stages of change. Understanding the readiness toward help-seeking and uptake of intervention in people with hearing loss based on TTM may help clinicians develop more focused management strategies. However, additional longitudinal and interventional studies are needed to further test the predictive validity of the stages of change model. American Academy of Audiology.

Publishing in scientific journals is an indicator of hospital quality and has become a standard of excellence for medical doctors and institutions. The aim of the study is to identify the scientific publications performed by Otolaryngology Departments in Spain within the period 2011-2015 and to compare them to a previous period between 1998-2002. Original papers published by Otolaryngology Departments in Spain in PubMed within 2011-2015 were retrieved. They were classified according to the type of journal published (international or Acta ORL Española) and the following subspecialty areas: Otology, Audiology and Neuro-Otology, Head and Neck Surgery (including Oncology), Rhinology and Paediatric ENT. Hospitals were ranked according to: number of original papers, accumulated impact factor and total number of publications. Between 2011 and 2015, 49342 publications were included in PubMed, 1.44% from Otolaryngology Departments in Spain. Between 1998 and 2002, 3.80% publications were from Spanish ENT departments. Of the 712 papers published within the period 2011-2015, 389 were published in Acta ORL Española and 323 in international journals. From the latter, 20.7% belong to the Otology area, 19.2% to Audiology-Neuro-otology, 30.6% to Head and Neck Surgery, 15.2% to Rhinology and 3.4% to Paediatric ENT. Five tertiary centres published at least 10 original papers in the same period. Spanish otolaryngology's contribution to international journals has decreased in the last 12 years. A few institutions are responsible for the majority of publications and they have notably increased the cumulative impact factor.

Cartilage is one of the most preferable grafts for tympanoplasty (TPL). The anatomical and audiological results and take rates of perichondrium attached cartilage island graft in tympanoplasty (PACIT) are presented herein. One hundred ninety four ears of 191 patients (108 male, 83 female) were evaluated retrospectively in terms of the type of surgery, graft take rate and hearing results. Type I, II, and III TPL were performed in 127 (65.46%), 45 (23.20%), and 22 (11.34%) ears, respectively. The overall mean preoperative pure tone average-air bone gaps (PTA-ABGs) for TPL types were 33.74 ± 9.60, 52.58 ± 9.07, and 56.58 ± 10.27 dB HL, respectively; postoperative mean values for TPL groups were 18.55 ± 9.25, 31.21 ± 4.36, and 44.84 ± 12.45 dB HL. Postoperative hearing results showed an improvement (≥ 10 dB) in 76.81% of ears with a mean gain of 20 dB HL (range 10-40 dB). However, 19.07% of ears showed no change (< 10, ≥ 0 dB) in hearing, and hearing worsened in 4.12% of ears (< 0 dB) postoperatively. Overall, graft take was 91.24% at least 13 months (mean 68.64) after surgery with a graft failure rate of 8.76%. Graft take was successful in TPL groups. Postoperative PTA-ABG results demonstrated significant improvement. The long-term eligibility of perichondrium attached cartilage island graft in TPL is emphasised with this study. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.

To assess the efficacy of a patient navigator intervention to decrease nonadherence to obtain audiological testing following failed screening, compared to those receiving the standard of care. Using a randomized controlled design, guardian-infant dyads, in which the infants had abnormal newborn hearing screening, were recruited within the first week after birth. All participants were referred for definitive audiological diagnostic testing. Dyads were randomized into a patient navigator study arm or standard of care arm. The primary outcome was the percentage of patients with follow-up nonadherence to obtain diagnostic testing. Secondary outcomes were parental knowledge of infant hearing testing recommendations and barriers in obtaining follow-up testing. Sixty-one dyads were enrolled in the study (patient navigator arm = 27, standard of care arm = 34). The percentage of participants nonadherent to diagnostic follow-up during the first 6 months after birth was significantly lower in the patient navigator arm compared with the standard of care arm (7.4% vs. 38.2%) (P = .005). The timing of initial follow-up was significantly lower in the navigator arm compared with the standard of care arm (67.9 days after birth vs. 105.9 days, P = .010). Patient navigation increased baseline knowledge regarding infant hearing loss diagnosis recommendations compared with the standard of care (P = .004). Patient navigation decreases nonadherence rates following abnormal infant hearing screening and improves knowledge of follow-up recommendations. This intervention has the potential to improve the timeliness of delivery of infant hearing healthcare; future research is needed to assess the cost and feasibility of larger scale implementation. 1b.

The aims of this study were to determine the distribution of risk factors associated with tinnitus analysing their role in the development of tinnitus and the effects of their interaction; to evidence the importance of a suitable and adequate clinical and audiologic assessment to avoid those modifiable risk factors responsible for cochlear dysfunction and tinnitus onset. 46 subjects with tinnitus and 74 controls were studied according to: age, sex, Body Mass Index (BMI), neck circumference, tobacco smoking, feeling fatigue or headache, self reporting snoring, hypertension, diabetes, coronary heart disease, and/or hyperlipidemia, and laboratory finding as lipid profile and levels of reactive oxygen metabolites (d-ROM). Audiological assessment was performed by multi-frequency audiometry (PTA(0.5-16 kHz)) and transient-evoked otoacoustic emissions (TEOAE diagnostic). Univariate analysis was performed to examine the association between determinants and occurrence of tinnitus; Mantel-Haenszel test (G.or) was used to investigate the joint effect of determinants on tinnitus. Tinnitus was more frequent among males with age >50 years; BMI >30 kg/m(2), neck circumference >40 cm, headache, hypertension, hypercholesterolemia resulted significant risk factors for tinnitus (P < 0.0001). Tinnitus group had more comorbidity (P < 0.0001) and worse audiometric thresholds (60.87 Vs 21.62% hearing loss; P < 0.0001) with respect to control group. The interaction between hypertension-BMI ≥ 30 kg/m(2) (G.or = 8.45) and smoking-hypercholesterolemia (G.or = 5.08) increases the risk of tinnitus (P < 0.0001). Our results underline that several factors either individually or jointly contribute to tinnitus onset; a comprehensive knowledge about tinnitus risk factors and associated clinical conditions could contribute to minimizing this disorder.

The aim of the present study was to verify whether drugs injected into the endolymphatic sac (ES) can reach the cochlea and possibly treat inner ear disorders. Prospective cohort study. Tertiary referral center, Otolaryngology Department, University of Verona. Patients with Ménière's disease (MD) who were candidates for ES decompression were selected. Nineteen subjects received dexamethasone (DEX) via injection into the ES. To objectively define whether substances administered into the ES could reach the cochlea, we added gadolinium (GD) in three patients. All subjects had intraoperative electrocorticogram recordings and an audiologic follow-up. The three subjects who underwent injection of the DEX-GD solution were followed-up with magnetic resonance imaging. The audiological data are presented during a follow-up period of 12 months. Intraoperative electrocochleography recordings revealed no changes in two patients and summating potentials and compound action potential latency and wave-form modifications in all the other subjects. GD distribution was observed from 48 hours to one week after ES injection into the cochlea of the three subjects injected with DEX-GD. GD-related enhancement of inner ear structures lasted more than two weeks in all subjects. Pure tone average results showed hearing improvement of at least 20 dB HL in 42 percent of patients (8 of 19) at the 12-month follow-up. Statistically significant differences emerged between the mean pure tone average of the ES procedure subjects at one and 12 months after surgery (P = 0.0096). This novel approach might reveal new prospects for treating viral, metabolic, autoimmune, and genetic disorders of the cochlea.

The objective of the study was to discuss the findings of intraoperative electrically evoked auditory brainstem response (eABR) test results with a recently designed intracochlear test electrode (ITE) in terms of their relation to decisions of cochlear or auditory brainstem implantation. This clinical study was conducted in Hacettepe University, Department of Otolaryngology, Head and Neck Surgery and Department of Audiology. Subjects were selected from inner ear malformation (IEM) database. Eleven subjects with profound sensorineural hearing loss were included in the current study with age range from 1 year 3 months to 4 years 3 months for children with prelingual hearing loss. There was only one 42-year-old post-lingual subject. eABR was recorded with an ITE and intraoperatively with an original cochlear implant (CI) electrode in 11 cases with different IEMs. Findings of eABR with ITE and their relation to the decision for CI or auditory brainstem implant (ABI) are discussed. Positive eABR test results were found to be dependent on close to normal cochlear structures and auditory nerve. The probability of positive result decreases with increasing degree of malformation severity. The prediction value of eABR via ITE on decision for hearing restoration was found to be questionable in this study. The results of eABR with ITE have predictive value on what we will get with the actual CI electrode. ITE appears to stimulate the cochlea like an actual CI. If the eABR is positive, the results are reliable. However, if eABR is negative, the results should be evaluated with preoperative audiological testing and MRI findings.

Technology for hearing loss--as We Know it, and as We Dream it.

2014-09-01

Worldwide demand for accessible hearing health technology continues to increase while the numbers of hearing healthcare specialists are grossly inadequate to meet this demand. Proliferation of innovative technology and the advent of greater access to global connectivity are providing an opportunity to identify and harness new resources that may change current audiological service delivery methods to maximize access, efficiency and impact. By searching through the most current literature and engaging in discussions with industry experts, it is possible to identify avenues that could increase services to those who have hearing loss with innovative healthcare technology. This article aims to review the current state as well as future trends of hearing health technology by addressing: Technology as We Know it; and Technology as We Dream it. Some of the newer technologies we have recently witnessed include: micro processors; personalized computing devices (e.g. smartphones); web-based applications; an expanding clinical repertoire with integrated test equipment; and globalization of telecommunications that opens the door to telehealth; and self-fitting of hearing aids. Yet, innovation continues scaffolding on recent successes with innovations for hearing healthcare expected to increase into the future. As technology and connectivity continue to evolve so should the practice of audiology adapt to the global needs by capitalizing on these advances to optimize service delivery access and sustainability. Capital investment in equipment will be dramatically reduced with smaller, lighter, less costly and more portable equipment. Individuals who live in remote regions with little or no hearing healthcare access can undergo valid assessments by a professional via telehealth. Web-based applications allow clinicians to expand their repertoire and reach of services.

To evaluate if severe jaundice is associated with acute auditory neuropathy spectrum disorder in otherwise healthy late preterm and term neonates. In a prospective observational study, all neonates who were admitted with severe jaundice at which exchange transfusion may be indicated as per American Academy of Pediatrics guidelines had comprehensive auditory evaluation performed before discharge to home. Neonates with infection, perinatal asphyxia, chromosomal disorders, cranio-facial malformations, or family history of childhood hearing loss were excluded. Comprehensive auditory evaluations (tympanometry, oto-acoustic emission tests, and auditory brainstem evoked responses) were performed by an audiologist unaware of the severity of jaundice. Total serum bilirubin and serum albumin were measured at the institutional chemistry laboratory using the Diazo and Bromocresol purple method, respectively. A total of 13 neonates with total serum bilirubin concentration at which exchange transfusion is indicated as per American Academy of Pediatrics were admitted to the Neonatal Intensive Care Unit over 3 month period. Six out of 13 neonates (46%) had audiological findings of acute auditory neuropathy spectrum disorder. There was no significant difference in gestational age, birth weight, hemolysis, serum albumin concentration, peak total serum bilirubin concentrations, and peak bilirubin:albumin molar ratio between six neonates who developed acute auditory neuropathy and seven neonates who had normal audiological findings. Only two out of six infants with auditory neuropathy spectrum disorder had clinical signs and symptoms of acute bilirubin encephalopathy. Our findings strongly suggest that auditory neuropathy spectrum disorder is a common manifestation of acute bilirubin-induced neurotoxicity in late preterm and term infants with severe jaundice. Our findings also suggest that comprehensive auditory evaluations should be routinely performed in neonates with severe jaundice irrespective of the presence of clinical findings of acute bilirubin encephalopathy.

Confirmation is provided for the belief that evoked potentials may reflect differences in hemispheric functioning that are marginal at best. Subjects were right-handed and audiologically normal men and women, and responses were recorded using standard EEG techniques. Subjects were instructed to listen for the targets while laying in a darkened sound booth. Different stimuli, speech and tone signals, were used. Speech sounds were shown to evoke a response pattern that resembles that to tone or clicks. Analysis of variances on peak amplitude and latency measures showed no significant differences between hemispheres, however, a Wilcoxon test showed significant differences in hemispheres for certain target tasks.

[Handling skills and utilization of hearing aids].

Seven hundred and fifty adult patients possessing hearing aids were interviewed with regard to utilization and handling skills. Although 71% were full-time users and 18% were part-time users, only 32% could handle their aids competently. Inhabitants of the county's major town clearly managed their aids better than residents of the remainder of the catchment area, despite the fact that 85% of the former group never sought counselling by hearing therapists. It is concluded that not only the traditional audiology professions, but also staff from other branches of the health and social services should participate more actively in the care of the hearing impaired.

A summary of issues regarding auditory processing disorder (APD) is presented, including some of the remaining questions and challenges raised by the articles included in the clinical forum. Evolution of APD as a diagnostic entity within audiology and speech-language pathology is reviewed. A summary of treatment efficacy results and issues is provided, as well as the continuing dilemma for speech-language pathologists (SLPs) charged with providing treatment for referred APD clients. The role of the SLP in diagnosing and treating APD remains under discussion, despite lack of efficacy data supporting auditory intervention and questions regarding the clinical relevance and validity of APD.

Occupational noise exposure and age correction: the problem of selection bias.

PubMed

Dobie, Robert A

2009-12-01

Selection bias often invalidates conclusions about populations based on clinical convenience samples. A recent paper in this journal makes two surprising assertions about noise-induced permanent threshold shift (NIPTS): first, that there is more NIPTS at 2 kHz than at higher frequencies; second, that NIPTS declines with advancing age. Neither assertion can be supported with the data presented, which were obtained from a clinical sample; both are consistent with the hypothesis that people who choose to attend an audiology clinic have worse hearing, especially at 2 kHz, than people of the same age and gender who choose not to attend.

A monosyllabic word test was administered to 114 postlingually-deaf adult cochlear implant (CI) recipients at numerous intervals from two weeks to two years post-initial CI activation. Biographic/audiologic information, electrode position, and cognitive ability were examined to determine factors affecting CI outcomes. Results revealed that Duration of Severe-to-Profound Hearing Loss, Age at Implantation, CI Sound-field Threshold Levels, Percentage of Electrodes in Scala Vestibuli, Medio-lateral Electrode Position, Insertion Depth, and Cognition were among the factors that affected performance. Knowledge of how factors affect performance can influence counseling, device fitting, and rehabilitation for patients and may contribute to improved device design. PMID:23348845

Cochlear implant surgery was performed in four Cantonese-speaking postlingually deaf Chinese adults, using the House/3M single channel device. This article outlines the methodology, including preoperative assessment and postoperative rehabilitation; and explains the necessary modifications in speech and audiologic work-up in Cantonese-speaking patients. Salient features of Cantonese phonetics, especially its tonal characteristics, are described. The findings of the study are presented. The results of the cochlear implant would suggest a performance superior to that of the hearing aid. Furthermore, the cochlear implant is able to detect tonal cues. This quality of the cochlear implant may prove to be a valuable asset to a tonal language-speaking cochlear implantee.

Over the last years, indications for cochlear implants (CIs) have changed dramatically. The benefits depend on the preconditions of the individual patient as well as on the subsequent (re)habilitation. Therefore, many variables influencing the hearing and speech perception of a CI user must be kept in mind. As an example, the special situation of children having Turkish as their mother tongue is described. The most convincing argument concerning (re)habilitation is its benefit. Indeed, this benefit represents the final standard of quality and serves as the yardstick for standard assessments of (re)habilitation quality. CI (re)habilitation includes medical, pedagogical, audiological, hearing and speech, and psychological therapeutic aspects.

Although newborn hearing screening programs have been introduced in most states in Australia, the prevalence of conductive hearing loss and middle ear pathology in the infants referred through these programs is not known. This study was designed to (1) evaluate the prevalence of conductive hearing loss and middle ear pathology in infants referred by a newborn hearing screening program in north Queensland, (2) compare prevalence rates of conductive hearing loss and middle ear pathology in indigenous and nonindigenous infants, and (3) review the outcomes of those infants diagnosed with conductive hearing loss and middle ear pathology. Retrospective chart review of infants referred to the Audiology Department of The Townsville Hospital was conducted. Chart review of 234 infants referred for one or both ears from a newborn hearing screening program in north Queensland was conducted. A total of 211 infants attended the diagnostic appointment. Review appointments to monitor hearing status were completed for 46 infants with middle ear pathology or conductive hearing loss. Diagnosis of hearing impairment was made using an age-appropriate battery of audiological tests. Results were analyzed for both initial and review appointments. Mean age at initial diagnostic assessment was 47.5 days (SD = 31.3). Of the 69 infants with middle ear pathology during initial diagnostic assessment, 18 had middle ear pathology with normal hearing, 47 had conductive hearing loss, and 4 had mixed hearing loss. Prevalence of conductive hearing loss in the newborns was 2.97 per 1,000 while prevalence of middle ear pathology (with or without conductive hearing loss) was 4.36 per 1,000. Indigenous Australians or Aboriginal and Torres Strait Islander (ATSI) infants had a significantly higher prevalence of conductive hearing loss and middle ear pathology than non-ATSI infants (35.19 and 44.45% vs 17.83 and 28.66%, respectively). ATSI infants also showed poor resolution of conductive hearing loss over time with 66.67% of ATSI infants reviewed showing persistent conductive hearing loss compared to 17.86% of non-ATSI infants. Medical management of 17 infants with persistent conductive hearing loss included monitoring, antibiotic treatment, examination under anesthesia, and grommet insertion. Conductive hearing loss was found to be a common diagnosis among infants referred through screening. ATSI infants had significantly higher rates of middle ear pathology and conductive hearing loss at birth and showed poor resolution of middle ear pathology over time compared to non-ATSI infants. Future research using a direct measure of middle ear function as an adjunct to the automated auditory brainstem response screening tool to distinguish conductive from sensorineural hearing loss may facilitate prioritization of infants for assessment, thus reducing parental anxiety and streamlining the management strategies for the respective types of hearing loss.

The current study was designed with three main aims: To document the level of emotional comprehension skills, from basic to more complex ones, reached by a wide sample of cochlear implant (CI) deaf children with at least 36 months of device use; To investigate subjective and audiological factors that can affect their emotional development; To identify, if present, a "critical age", in which early intervention might positively affect adequate emotional competence development. This is an observational cohort study. Children with congenital severe/profound deafness were selected based on: aged by 4-11 years, minimum of 36 months of CI use, Italian as the primary language in the family; normal cognitive level and absence of associated disorders or socio-economic difficulties. Audiological characteristics and language development were assessed throughout standardized tests, to measure speech perception in quiet, lexical comprehension and production. The development of emotions' understanding was assessed using the Test of Emotion Comprehension (TEC) of Pons and Harris, a hierarchical developmental model, where emotion comprehension is organized in 3 Stages (external, mental and reflective). Statistical analysis was accomplished via the Spearman Rank Correlation Coefficient, to study the relationship between the personal and audiological characteristics; a multivariate linear regression analysis was carried out to find which variables were better associated with the standardized TEC values; a chi-squared test with Yate's continuity correction and Mann-Whitney U test were used to account for differences between continuous variables and proportions. 72 children (40 females, 32 males) with a mean age of 8.1 years were included. At TEC score, 57 children showed normal range performances (79.17% of recipients) and 15 fell below average (20.83% of recipients). The 16.63% of older subjects (range of age 8-12 years) didn't master the Stage 3 (reflective), which is normally acquired by 8 years of age and failed 2 or all the 3 items of this component. Subjects implanted within 18 months of age had better emotion comprehension skills. TEC results were also positively correlated with an early diagnosis, a longer implant use, better auditory skills and higher scores on lexical and morphosintactic tests. On the contrary, it was negatively correlated with the presence of siblings and the order of birth. The gender, the side and the severity of deafness, type of implant and strategy were not correlated. Early implanted children have more chance to develop adequate emotion comprehension, especially when the complex aspects are included, due to the very strong link between listening and language skills and emotional development. Furthermore, longer CI auditory experience along with early intervention allows an adequate communication development which positively influences the acquisition of such competencies.

To report three cases of patients with Systemic Sclerosis (SSc) and retrocochlear impairments. This is a case report of three individuals with SSc and retrocochlear impairments assisted at a rheumatology outpatient clinic. All individuals underwent Brainstem Auditory Evoked Potential (BAEP) and, when necessary, audiometry. All three individuals presented sensorineural hearing loss. Although no retrocochlear impairment was identified in the basic audiologic evaluation, the BAEP results were altered. Retrocochlear impairments were present in the individuals under study, both in the absolute latencies and interpeak interval, thereby demanding the attention of rheumatologists and speech-language pathologists to such changes during the monitoring of SSc patients. The results also show a need for epidemiological studies on the theme.

The number of people over 65 years of age is increasing, and many of those individuals will have sensorineural hearing loss in addition to other chronic health conditions. Future hearing health care providers need to be sensitive to the needs of elderly patients. The purpose of this article is to describe an experiential learning curriculum used in the Doctor of Audiology program in the Department of Communication Sciences and Disorders at the University of Oklahoma Health Sciences Center. The curriculum uses simulations of sensory disorders common in the elderly to transform knowledge and active experience into patient-centered, empathetic counseling skills and strategies to use with older adults with hearing loss.

To report a case of successful bone-anchored hearing aid implantation in an adult patient with type III osteogenesis imperfecta, which is commonly regarded as a contraindication to this procedure. A 45-year-old man with type III osteogenesis imperfecta presented with mixed hearing loss. There was a mild sensorineural component in both ears, with an air-bone gap between 45 and 50 dB HL. He was implanted with a bone-anchored hearing aid. The audiological outcome was good, with no complications and good implant stability (as measured by resonance frequency analysis). To our knowledge, this is the first recorded case of bone-anchored hearing aid implantation in a patient with osteogenesis imperfecta.

Norrie disease is an X-linked recessive syndrome of blindness, deafness, and mental retardation. A knock-out mouse model with an Ndp gene disruption was studied. We examined the hearing phenotype, including audiological, histological, and vascular evaluations. As is seen in humans, the mice had progressive hearing loss leading to profound deafness. The primary lesion was localized to the stria vascularis, which houses the main vasculature of the cochlea. Fluorescent dyes showed an abnormal vasculature in this region and eventual loss of two-thirds of the vessels. We propose that one of the principal functions of norrin in the ear is to regulate the interaction of the cochlea with its vasculature.

Risk factors of sensorineural hearing loss in preterm infants.

Borradori, C; Fawer, C L; Buclin, T; Calame, A

1997-01-01

Among 547 preterm infants of < or = 34 weeks gestation born between 1987 and 1991, 8 children (1.46%) developed severe progressive and bilateral sensorineural hearing loss. Perinatal risk factors of infants with hearing loss were compared with those of two control groups matched for gestation and birth weight and for perinatal complications. Our observations demonstrated an association of hearing loss with a higher incidence of perinatal complications. Ototoxicity appeared closely related to a prolonged administration and higher total dose of ototoxic drugs, particularly aminoglycosides and furosemide. Finally, we strongly recommend to prospectively and regularly perform audiologic assessment in sick preterm children as hearing loss is of delayed onset and in most cases bilateral and severe.

Theoretical Issues of Validity in the Measurement of Aided Speech Reception Threshold in Noise for Comparing Nonlinear Hearing Aid Systems.

PubMed

Naylor, Graham

2016-07-01

Adaptive Speech Reception Threshold in noise (SRTn) measurements are often used to make comparisons between alternative hearing aid (HA) systems. Such measurements usually do not constrain the signal-to-noise ratio (SNR) at which testing takes place. Meanwhile, HA systems increasingly include nonlinear features that operate differently in different SNRs, and listeners differ in their inherent SNR requirements. To show that SRTn measurements, as commonly used in comparisons of alternative HA systems, suffer from threats to their validity, to illustrate these threats with examples of potentially invalid conclusions in the research literature, and to propose ways to tackle these threats. An examination of the nature of SRTn measurements in the context of test theory, modern nonlinear HAs, and listener diversity. Examples from the audiological research literature were used to estimate typical interparticipant variation in SRTn and to illustrate cases where validity may have been compromised. There can be no doubt that SRTn measurements, when used to compare nonlinear HA systems, in principle, suffer from threats to their internal and external/ecological validity. Interactions between HA nonlinearities and SNR, and interparticipant differences in inherent SNR requirements, can act to generate misleading results. In addition, SRTn may lie at an SNR outside the range for which the HA system is designed or expected to operate in. Although the extent of invalid conclusions in the literature is difficult to evaluate, examples of studies were nevertheless identified where the risk of each form of invalidity is significant. Reliable data on ecological SNRs is becoming available, so that ecological validity can be assessed. Methodological developments that can reduce the risk of invalid conclusions include variations on the SRTn measurement procedure itself, manipulations of stimulus or scoring conditions to place SRTn in an ecologically relevant range, and design and analysis approaches that take account of interparticipant differences.

Williams syndrome is a neurodevelopmental disorder associated with cardiovascular problems, facial abnormalities and several behavioural and neurological disabilities. It is also characterized by some typical audiological features including abnormal sensitivity to sounds, cochlear impairment related to the outer hair cells of the basal turn of the cochlea, and sensorineural or mixed hearing loss, predominantly in the high frequency range. The aim of this report is to describe a follow-up study of auditory function in a cohort of children affected by this syndrome. 24 patients, aged 5-14 years, were tested by means of air/bone conduction pure-tone audiometry, immittance test and transient evoked otoacoustic emissions. They were evaluated again 5 years after the first assessment, and 10 of them underwent a second follow-up examination after a further 5 years. The audiometric results showed hearing loss, defined by a pure tone average >15 dB HL, in 12.5% of the participants. The incidence of hearing loss did not change over the 5-year period and increased to 30% in the patients who underwent the 10-year follow-up. Progressive sensorineural hearing loss was detected in 20% of the patients. A remarkable finding of our study regarded sensorineural hearing impairment in the high frequency range, which increased significantly from 25% to 50% of the participants over the 5-year period. The increase became even more significant in the group of patients who underwent the 10-year follow-up, by which time the majority of them (80%) had developed sensorineural hearing loss. Otoacoustic emissions were found to be absent in a high percentage of patients, thus confirming the cochlear fragility of individuals with Williams syndrome. Our study verified that most of the young Williams syndrome patients had normal hearing sensitivity within the low-middle frequency range, but showed a weakness regarding the high frequencies, the threshold of which worsened significantly over time in most patients.

2016-02-01

The past decade has yielded changes in the education and training of audiologists and technological advancements that have become widely available for clinical balance function testing. It is unclear if recent advancements in vestibular instrumentation or the transition to an AuD degree have affected audiologists' vestibular clinical practice or opinions. The purpose of this study was to examine predominant opinions and practices for vestibular assessment (VA) and vestibular rehabilitation (VR) over the past decade and between master's- and AuD-level audiologists. A 31-question survey was administered to audiologists via U.S. mail in 2003 (N = 7,500) and electronically in 2014 (N = 9,984) with a response rate of 12% and 10%, respectively. There was an increase in the number of audiologists providing vestibular services in the past decade. Most respondents agreed that audiologists were the most qualified professionals to conduct VA. Less than half of the surveyed audiologists felt that graduate training was adequate for VA. AuD-level audiologists were more satisfied with graduate training and felt more comfortable performing VA compared to master's-level audiologists. Few respondents agreed that audiologists were the most qualified professionals to conduct VR or that graduate training prepared them to conduct VR. The basic vestibular test battery was unchanged across surveys and included: calorics, smooth pursuit, saccades, search for spontaneous, positional, gaze and optokinetic nystagmus, Dix-Hallpike, case history, and hearing evaluation. There was a trend toward greater use of air (versus water) calorics, videonystagmography (versus electronystagmography), and additional tests of vestibular and balance function. VA is a growing specialty area in the field of audiology. Better training opportunities are needed to increase audiologists' knowledge and skills for providing vestibular services. The basic tests performed during VA have remained relatively unchanged over the past 10 yr. American Academy of Audiology.

Defects in USH2A cause both isolated retinal disease and Usher syndrome (ie, retinal disease and deafness). To gain insights into isolated/nonsyndromic USH2A retinopathy, we screened USH2A in 186 probands with recessive retinal disease and no hearing complaint in childhood (discovery cohort) and in 84 probands with recessive retinal disease (replication cohort). Detailed phenotyping, including retinal imaging and audiological assessment, was performed in individuals with two likely disease-causing USH2A variants. Further genetic testing, including screening for a deep-intronic disease-causing variant and large deletions/duplications, was performed in those with one likely disease-causing change. Overall, 23 of 186 probands (discovery cohort) were found to harbour two likely disease-causing variants in USH2A. Some of these variants were predominantly associated with nonsyndromic retinal degeneration (‘retinal disease-specific'); these included the common c.2276 G>T, p.(Cys759Phe) mutation and five additional variants: c.2802 T>G, p.(Cys934Trp); c.10073 G>A, p.(Cys3358Tyr); c.11156 G>A, p.(Arg3719His); c.12295-3 T>A; and c.12575 G>A, p.(Arg4192His). An allelic hierarchy was observed in the discovery cohort and confirmed in the replication cohort. In nonsyndromic USH2A disease, retinopathy was consistent with retinitis pigmentosa and the audiological phenotype was variable. USH2A retinopathy is a common cause of nonsyndromic recessive retinal degeneration and has a different mutational spectrum to that observed in Usher syndrome. The following model is proposed: the presence of at least one ‘retinal disease-specific' USH2A allele in a patient with USH2A-related disease results in the preservation of normal hearing. Careful genotype–phenotype studies such as this will become increasingly important, especially now that high-throughput sequencing is widely used in the clinical setting. PMID:25649381

Male students’ perceptions about gender imbalances in a speech-language pathology and audiology training programme of a South African institution of higher education

PubMed Central

2018-01-01

Background The professions of speech-language pathology and audiology (SLPA) are characterised by occupational gender segregation. Reasons given by men are a lack of awareness of SLPA; a perception of poor salaries; a perception of poor working conditions; a stereotype that the profession is a female occupation; and a perception that working with children is feminine. Objectives The aim of this study was to describe the perceptions of male students in a specific SLPA training programme regarding gender imbalances. The objectives were to describe the influences of gender on the career orientation of students, the factors shaping students’ career choices and the experiences of students during their undergraduate training. Method This study followed a quantitative descriptive survey design. Thirty-one conveniently sampled male SLPA students, across different years of study, completed a self-administered questionnaire. Results Participants indicated that they did not believe in the gendered nature of occupations and that SLPA are not ‘female only’ professions. They (65%) recorded that they considered salary and career prospects for choosing a career, and 74% specified that they chose SLPA because of a desire to help people. The perception of male students regarding their training appears to be positive as participants are comfortable with the clinical (71%) and learning (77%) activities. However, barriers were reported and some lecture information may be more obvious or applicable to female students. A need was identified to address the issue of working alone with paediatric clients and pertains to the societal awareness regarding sexual harassment of children, which may impact spontaneity in engagements. Conclusion The recruitment of male students should be prioritised to better reflect the client population served by the professions. Recommendations include career counselling in rural schools, recruitment campaigns to identify interested students, public awareness regarding the professions and guidance regarding working with paediatric clients.

To characterize the audiological features in the infants with otitis media with effusion (OME) and to investigate the utility of variety of objective audiometry methods in diagnosis and intervention on OME. Fifty six infants (40 males and 16 females) were investigated, who were referred to our clinic at the General Hospital of Chinese People's Liberation Army by the other hospitals from December 2004 to June 2007 when the infants were diagnosed or highly suspected of OME. The ages at the initial diagnosis ranged from 42 days to three years, with an average of five months. The infants, after receiving the conventional otolaryngological exams, were subjected to the tests of auditory brainstem response (ABR), otoacoustic emission (OAE), tympanometry (226 Hz and 1000 Hz) and behaviors audiometry. Among 56 affected infants, 87 ears were diagnosed with OME, of which 31 infants were affected bilateral and 25 with monaural. For the 49 infants who received hearing screening at birth, 36 infants were referred at the initial screening. For the 52 infants who received repeated screening, all subjects were referred. Six infants without receiving hearing screening came to clinic when their parents observed their kids' hearing impairment. Among the 52 cases (104 ears) who received tympanometry test, 20 subjects (28 ears) showed B or C type tympanometry curve. Thirty-nine cases (78 ears) were given tympanometry test at 1000 Hz, of which 38 cases (55 ears) showed abnormal hearing. Among 56 infants (112 ears) with ABR test, 49 subjects (74 ears) exhibited prolonged ABR type I curve. All 56 infants (112 ears) received OAE test, of which 55 subjects (81 ears) were referred. Four infants (8 ears) accepted the behavior test and all of them showed A-B Gap. The combined tympanometry test at both 226 Hz and 1000 Hz, ABR latency or threshold test, infant's behavior test and OAE, used jointly, enable characterizing better OME in infants, thus helping early diagnosis of this hearing disorder.

The differential diagnosis of vertigo in children is extensive. Otitis media and middle ear effusion could be the most common causes of vertigo in children, but there are some problems in detecting the other causes for vertigo because they are one of most frequent diseases of childhood. The purpose of this study is to review the clinical characteristics and both the audiological and vestibular findings of vertigo in children with normal eardrums, who do not show otitis media or middle ear effusion, and to assist in making a differential diagnosis of vertigo. The fifty five children (< 16 years old) with vertigo, who visited the Department of Otolaryngology, Ajou University Hospital, Suwon, South Korea between January 1995 and December 2001 were selected for this study. These excluded the patients with abnormal eardrums/tympanograms or those that did not perform questionnaires, audiological, or vestibular evaluations. They were retrospectively analyzed for clinical symptoms, vestibular functions, and differential diagnosis. The most common causes for vertigo in children were migraine in 17 (30.9%) and benign paroxysmal vertigo of childhood (BPVC) in 14 (25.5%). Other less frequent causes included four cases of trauma, two cases each of Meniere's disease, delayed endolymphatic hydrops, benign positional vertigo, and one case only for cerebellopontine angle tumor, seizure, acute vestibular neuritis, juvenile rheumatoid arthritis, leaving ten cases (18.2%) as unclassified. Abnormal findings were noted in 13 (23.6%) in pure tone audiogram, 3 (5.5%) in positioning test, 6 (10.9%) in bithermal caloric test, and 36 (65.5%) in rotation chair test. The vertigo in children with normal eardrums, who did not show otitis media or middle ear effusion, was most commonly caused by migraine and BPVC. These findings have shown to be very different from those with adult vertigo. The evaluation of vertigo in children requires a questionnaire for extensive and complete history taking, audiograms and vestibular function tests. And in selected cases, electroencephalography, hematological evaluation, imaging of the brain or temporal bone should be performed.

To analyze cost and compare cholesteatoma recidivism and hearing outcomes with single-stage and second-look operative strategies. Retrospective review and cost analysis. Adult and pediatric patients who underwent a tympanoplasty with mastoidectomy for cholesteatoma with a single-stage or second-look operative strategy were identified. Variables included procedure approach, residual or recurrent cholesteatoma, ossicular chain reconstruction frequency, and operative complications. Audiologic outcomes included pre-/postoperative air bone gap (ABG) and word recognition score (WRS). Cost analysis included charges for consultation and follow-up visits, surgical procedures, computed tomography temporal bone scans, and audiology visits. One hundred and six patients had a tympanoplasty with mastoidectomy for cholesteatoma, with 80 canal wall-up procedures (CWU) as initial approach. Of these, 46 (57.5%) CWU patients had a planned second look. Two (4.3%) CWU patients had recurrent cholesteatoma and 20 (43.4%) had residual identified at second look. Four (11.7%) single-stage CWU strategy patients developed recurrent cholesteatoma. There was no significant difference in pre-/postoperative ABG and WRS between second look and single stage (P > 0.05). Compared to second-look patients, single-stage patients had significantly fewer postoperative visits (6.32 vs. 10.4; P = 0.007), and significantly lower overall charges for care ($23,529. vs. $41.411; P < 0.0001). The goal of cholesteatoma surgery is to produce a safe ear, and a second-look strategy after CWU has historically been used to evaluate for recurrent or residual disease. The cholesteatoma recurrence rate at a second look after a CWU tympanoplasty-mastoidectomy is low. Costs of operative procedures are a significant proportion of healthcare resource expenditures. Considering the low rate of cholesteatoma recurrence and relatively high cost of care, implementation of a second-look strategy should be individually tailored and not universally performed. 4.

Despite recent advancement in the prediction of cochlear implant outcome, the benefit of bilateral procedures compared to bimodal stimulation and how we predict speech perception outcomes of sequential bilateral cochlear implant based on bimodal auditory performance in children remain unclear. This investigation was performed: (1) to determine the benefit of sequential bilateral cochlear implant and (2) to identify the associated factors for the outcome of sequential bilateral cochlear implant. Observational and retrospective study. We retrospectively analyzed 29 patients with sequential cochlear implant following bimodal-fitting condition. Audiological evaluations were performed; the categories of auditory performance scores, speech perception with monosyllable and disyllables words, and the Korean version of Ling. Audiological evaluations were performed before sequential cochlear implant with the bimodal fitting condition (CI1+HA) and one year after the sequential cochlear implant with bilateral cochlear implant condition (CI1+CI2). The good Performance Group (GP) was defined as follows; 90% or higher in monosyllable and bisyllable tests with auditory-only condition or 20% or higher improvement of the scores with CI1+CI2. Age at first implantation, inter-implant interval, categories of auditory performance score, and various comorbidities were analyzed by logistic regression analysis. Compared to the CI1+HA, CI1+CI2 provided significant benefit in categories of auditory performance, speech perception, and Korean version of Ling results. Preoperative categories of auditory performance scores were the only associated factor for being GP (odds ratio=4.38, 95% confidence interval - 95%=1.07-17.93, p=0.04). The children with limited language development in bimodal condition should be considered as the sequential bilateral cochlear implant and preoperative categories of auditory performance score could be used as the predictor in speech perception after sequential cochlear implant.

Introduction The holistic management of hearing loss (HL) requires an understanding of factors that predict hearing aid (HA) use and benefit beyond the acoustics of listening environments. Although several predictors have been identified, no study has explored the role of audiological, cognitive, behavioural and physiological data nor has any study collected real-time HA data. This study will collect ‘big data’, including retrospective HA logging data, prospective clinical data and real-time data via smart HAs, a mobile application and biosensors. The main objective is to enable the validation of the EVOTION platform as a public health policy-making tool for HL. Methods and analysis This will be a big data international multicentre study consisting of retrospective and prospective data collection. Existing data from approximately 35 000 HA users will be extracted from clinical repositories in the UK and Denmark. For the prospective data collection, 1260 HA candidates will be recruited across four clinics in the UK and Greece. Participants will complete a battery of audiological and other assessments (measures of patient-reported HA benefit, mood, cognition, quality of life). Patients will be offered smart HAs and a mobile phone application and a subset will also be given wearable biosensors, to enable the collection of dynamic real-life HA usage data. Big data analytics will be used to detect correlations between contextualised HA usage and effectiveness, and different factors and comorbidities affecting HL, with a view to informing public health decision-making. Ethics and dissemination Ethical approval was received from the London South East Research Ethics Committee (17/LO/0789), the Hippokrateion Hospital Ethics Committee (1847) and the Athens Medical Center’s Ethics Committee (KM140670). Results will be disseminated through national and international events in Greece and the UK, scientific journals, newsletters, magazines and social media. Target audiences include HA users, clinicians, policy-makers and the general public. Trial registration number NCT03316287; Pre-results. PMID:29449298

The Human Immunodeficiency Virus (HIV) and infections related to it can affect multiple sites in the hearing system. The use of High-Activity Anti-Retroviral Therapy (HAART) can cause side effects such as ototoxicity. Thus, no consistent patterns of hearing impairment in adults with Human Immunodeficiency Virus / Acquired Immune Deficiency Syndrome have been established, and the problems that affect the hearing system of this population warrant further research. This study aimed to compare the audiological and electrophysiological data of Human Immunodeficiency Virus-positive patients with and without Acquired Immune Deficiency Syndrome, who were receiving High-Activity Anti-Retroviral Therapy, to healthy individuals. It was a cross-sectional study conducted with 71 subjects (30-48 years old), divided into groups: Research Group I: 16 Human Immunodeficiency Virus-positive individuals without Acquired Immunodeficiency Syndrome (not receiving antiretroviral treatment); Research Group II: 25 Human Immunodeficiency Virus-positive individuals with Acquired Immunodeficiency Syndrome (receiving antiretroviral treatment); Control Group: 30 healthy subjects. All individuals were tested by pure-tone air conduction thresholds at 0.25-8kHz, extended high frequencies at 9-20kHz, electrophysiological tests (Auditory Brainstem Response - ABR, Middle Latency Responses - MLR, Cognitive Potential - P300). Research Group I and Research Group II had higher hearing thresholds in both conventional and high frequency audiometry when compared to the control group, prolonged latency of waves I, III, V and interpeak I-V in Auditory Brainstem Response and prolonged latency of P300 Cognitive Potential. Regarding Middle Latency Responses, there was a decrease in the amplitude of the Pa wave of Research Group II compared to the Research Group I. Both groups with Human Immunodeficiency Virus had higher hearing thresholds when compared to healthy individuals (group exposed to antiretroviral treatment showed the worst hearing threshold) and seemed to have lower neuroelectric transmission speed along the auditory pathway in the brainstem, subcortical and cortical regions.

Providing a model of a comprehensive free audiologic program may assist other health care professionals in developing their own similar program. To describe the structure, feasibility, and outcomes of a free subspecialty clinic providing hearing aids to develop a paradigm for other programs interested in implementing similar projects. A retrospective case series was conducted from September 1, 2013, through March 31, 2016. In a partnership between a free independent clinic for indigent patients and an academic medical center, 54 indigent patients were referred to the clinic for audiograms. A total of 50 of these patients had results of audiograms available for review and were therefore included in the study; 34 of these 50 patients were determined to be eligible for hearing aid fitting based on audiometric results. Free audiometric testing, hearing aid fitting, and hearing aid donation. The number of hearing aids donated, number of eligible patients identified, number of patients fitted with hearing aids, and work effort (hours) and start-up costs associated with implementation of this program were quantified. A total of 54 patients (31 women [57.4%] and 23 men [42.6%]; median age, 61 years; range, 33-85 years) had audiograms performed, and 84 hearing aids were donated to the program. The patients were provided with free audiograms, hearing aid molds, and hearing aid programming, as well as follow-up appointments to ensure continued proper functioning of their hearing aids. Since 2013, a total of 34 patients have been determined to be eligible for the free program and were offered hearing aid services. Of these, 20 patients (59%) have been fitted or are being fitted with free hearing aids. The value of services provided is estimated to be $2260 per patient. It is feasible to provide free, comprehensive audiologic care, including hearing aids and fitting, in a well-established, free clinic model. The opportunity for indigent patients to use hearing aids at minimal personal cost is a major step forward in improving access to high-quality care.

Since the psychosocial effects of hearing loss are different in the spouse (SP) than in the person with hearing loss (PHL), it seems reasonable that rehabilitation programs designed for PHLs may need to be adapted to benefit SPs. To evaluate the effectiveness of training in communication strategies and psychosocial exercises for SPs of PHLs by determining whether SPs who completed the group class had improved mood, reduced stress, improved marital communication, and greater awareness of their partners' hearing loss-related quality of life (HL-QOL) in comparison with SPs who did not participate in a group class. Additionally, to determine whether PHLs of SPs who participated in a group audiological rehabilitation (AR) class had significantly improved mood, reduced stress, improved marital communication, and better HL-QOL scores in comparison with PHLs whose SPs did not participate in a group class. A randomized controlled study. A total of 72 individuals participated in the study, 36 PHLs and 36 SPs. The PHLs were hearing aid users or cochlear implant users; the SPs had normal or near normal hearing. PHLs in the control group participated in a traditional group AR program while their SPs received no treatment. PHLs in the experimental group also participated in a traditional group AR program while their SPs participated in a treatment program designed for SPs of PHLs. Classes consisted of 90 min sessions meeting once a week for four weeks. All participants completed questionnaires measuring HL-QOL (the SPs filled out third-party reports of HL-QOL), stress, mood (positive affect and negative affect), and communication in the marriage. Scales were completed three times: prior to the AR program, within two weeks after completing the AR program, and 6 mo later. SP awareness of their PHL's HL-QOL was measured by comparing preclass and 6 mo scores with reported critical difference values. Preclass, postclass and 6 mo data were examined with repeated measures ANOVAs. All SPs reported significant improvements in third-party HL-QOL between the preclass and postclass visit. At the 6 mo visit, these reports remained consistent in the control SPs but declined in the experimental SPs. Awareness of HL-QOL in PHLs was improved in SPs who participated in AR classes and remained consistent in SPs who did not. All SPs demonstrated a trend (moderate effect sizes) for decreased stress and decreased negative affect after they and/or their partners completed the AR program. All PHLs demonstrated significant improvements in HL-QOL, significant reductions in stress, significant decreases in negative affect, and significant improvements in marital communication. There were no differences in outcome across the experimental and control PHLs. When PHLs participate in an AR program, they receive significant improvements in QOL (quality of life). Congruence (as defined by similar scores) between SP and PHL assessments of HL-QOL improved in the experimental group, suggesting that the principal impact of the AR program on SPs was improved understanding of PHL experiences with hearing loss.

2011-01-01

Pure-tone, air-conduction audiograms notched at 4000 Hz have long been considered the signature configuration for noise-induced hearing loss even though there is an extensive literature that does not mesh with this simple explanation. There are many reports of notched audiograms from individuals with no history of noise exposure and, conversely, reports of audiograms with no notches from individuals with a history of noise exposure. Recent reports increasingly suggest that unilateral 4000 Hz notches are common. The prevalence of notched audiograms at 4000 Hz is dependent on the definition of the notch and the population under study. To examine the prevalence and characteristics of audiograms that are notched at 4000 Hz. Retrospective, descriptive. The participants were 3430 veterans evaluated in the Audiology Clinic at the VA Medical Center, Mountain Home, Tennessee. The mean age was 62.3 yr. Data Collection and Analyses: The data were collected in the course of a 60 min, routine audiological evaluation. In addition to pure-tone audiometry, a history, otoscopy, speech audiometry in quiet and in noise, and aural-acoustic immittance measures were included in the clinic protocol but were not evaluated in this report. A notch was defined when the 4000 Hz threshold minus the 2000 Hz threshold and the 4000 Hz threshold minus the 8000 Hz threshold both were ≥10 dB. Overall the mean LE (left ear) thresholds at 2000, 3000, and 4000 Hz were at hearing levels 2-3 dB higher than the hearing levels for the corresponding mean RE (right ear) thresholds; the differences were significant. A notched audiogram was observed in 40.6% of the participants in at least one ear with 15.4% having bilateral notches, 28.8% LE notches, and 27.1% RE notches. Unilateral 4000 Hz notches were almost twice as prevalent as bilateral 4000 Hz notches. Viewed as a function of age, notched audiograms were most common (∼35% of the participants) in the 40 and 50 yr groups with a diminishing prevalence in the 60-80 yr groups. The mean notch depth at 4000 Hz was consistently 20-26 dB across the seven age groups. In comparison to the thresholds of the audiograms that were not notched, the thresholds of the audiograms with 4000 Hz notches (1) at 250-2000 Hz were at hearing levels 2-3 dB lower, (2) at 3000 and 4000 Hz were at hearing levels 8-17 dB higher, and (3) at 8000 Hz were at hearing levels 3-4 dB lower; the threshold differences were significant at all frequencies for both ears. The data suggest that unilateral, 4000 Hz notched audiograms are as common or more common than bilateral notched audiograms and that unilateral notched audiograms are equally common for the LE and RE. The prevalence and characteristics of 4000 Hz notched audiograms in this veteran sample are similar to those observed in the population as a whole. American Academy of Audiology.

Towards the end of my time at Trousseau, it was a huge honour to be asked if I would like to consider staying on as an observer until October, with a view to continuing on, after that, in a Chef de Clinique appointment. This was a golden opportunity that I would have dearly snapped up. Unfortunately, the timing clashed with other previously made, very solid, arrangements. I am tremendously grateful to The Journal of Laryngology & Otology for supporting this Fellowship, and also to Professor Garabedian and his team for their exceptional hospitality, approachability and generosity. I have made some excellent friends in Paris. Overall, this was an extremely positive and valuable experience both in terms of family and work.

To evaluate patients with the Usher syn drome in Puerto Rico. Three patients with the Usher syndrome underwent an ophthalmic and audiologic evaluation; and genetic linkage analysis. All patients were legally blind based on visual acuity and visual field results. Two patients had macular edema as shown on Stratus OCT. All patients had moderate hearing loss as part of the syndrome. A patient, and two family members had three mutations leading to protein changes including: p.S4588Y; p.Y4505C; and p.14474M. Phenotypic findings in patients with the Usher syndrome in Puerto Rico are similar to those previously reported. However, to our knowledge, neither these mutations nor OCT findings have been previously described in patients with the syndrome.

This paper describes the listening habits and musical enjoyment of postlingually deafened adults who use cochlear implants. Sixty-five implant recipients (35 females, 30 males) participated in a survey containing questions about musical background, prior involvement in music, and audiologic success with the implant in various listening circumstances. Responses were correlated with measures of cognition and speech recognition. Sixty-seven implant recipients completed daily diaries (7 consecutive days) in which they reported hours spent in specific music activities. Results indicate a wide range of success with music. In general, people enjoy music less postimplantation than prior to hearing loss. Musical enjoyment is influenced by the listening environment (e.g., a quiet room) and features of the music.

Quantifying auditory handicap. A new approach.

PubMed

Jerger, S; Jerger, J

1979-01-01

This report describes a new audiovisual test procedure for the quantification of auditory handicap (QUAH). The QUAH test attempts to recreate in the laboratory a series of everyday listening situations. Individual test items represent psychomotor tasks. Data on 53 normal-hearing listeners described performance as a function of the message-to-competition ratio (MCR). Results indicated that, for further studies, an MCR of 0 dB represents the condition above which the task seemed too easy and below which the task appeared too difficult for normal-hearing subjects. The QUAH approach to the measurement of auditory handicap seems promising as an experimental tool. Further studies are needed to describe the relation of QUAH results (1) to clinical audiologic measures and (2) to more traditional indices of auditory handicap.

This longitudinal study evaluated subjective, behavioral, and objective auditory function in 83 explosion survivors. Subjects were evaluated quarterly for 1 year with conventional pure-tone and extended high-frequencies audiometry, otoscopic inspections, immittance and speech audiometry, and questionnaires. There was no obvious relationship between subject location and symptoms or test results. Tinnitus, distorted hearing, loudness sensitivity, and otalgia were common symptoms. On average, 76 percent of subjects had predominantly sensorineural hearing loss at one or more frequencies. Twenty-four percent of subjects required amplification. Extended high frequencies showed evidence of acoustic trauma even when conventional frequencies fell within the normal range. Males had significantly poorer responses than females across frequencies. Auditory status of the group was significantly compromised and unchanged at the end of 1-year postblast.

2006-01-01

The number and proportion of older adults in the United States population is increasing, and more clinical audiologists will be called upon to deliver hearing care to the approximately 35% to 50% of them who experience hearing difficulties. In recent years, the characteristics and sources of receptive communication difficulties in older individuals have been investigated by hearing scientists, cognitive psychologists, and audiologists. It is becoming increasingly apparent that cognitive compromises and psychoacoustic auditory processing disorders associated with aging may contribute to communication difficulties in this population. This paper presents an overview of best practices, based on our current knowledge base, for clinical management of older individuals with limitations in cognitive or psychoacoustic auditory processing capabilities, or both, that accompany aging.

Are chirps better than clicks and tonebursts for evoking middle latency responses?

PubMed

Atcherson, Samuel R; Moore, Page C

2014-06-01

The middle latency response (MLR) is considered a valid clinical tool for assessing the integrity of cortical and subcortical structures. Several investigators have demonstrated that a rising frequency chirp stimulus is capable of eliciting not only larger wave V amplitudes but larger MLR components as well. However, the chirp has never been specifically examined in a hemispheric electrode montage setup that is typical for neurodiagnostic application and site-of-lesion testing. The purpose of this study was to examine the effect of chirp, click, and toneburst stimuli on MLR waveform peak latency and peak-to-peak amplitude in a hemispheric electrode montage setup. This study used a repeated-measures design. A total of 10 young adult participants (3 males, 7 females) with normal hearing were recruited and had negative histories of audiologic, otologic, and neurologic involvement, and no reported language or learning difficulties. MLR latencies (Na, Pa, Nb, and Pb) and peak-to-peak amplitudes (Na-Pa, Pa-Nb, and Nb-Pb) were measured for all conditions and were statistically evaluated for left hemisphere-right ear (C3-A2) and right hemisphere-left ear (C4-A1) recordings. Statistical analyses revealed no significant difference between C3-A2 and C4-A1 peak-to-peak amplitudes; therefore, data were collapsed. Stimulus comparisons revealed that Na evoked by tonebursts were statistically prolonged compared with both chirp and click, and that both Na-Pa and Pa-Nb peak-to-peak amplitudes were statistically larger for chirps compared with both clicks and tonebursts, and for clicks compared with tonebursts. The results of this study support the hypothesis that a chirp would offer a clinical advantage to the click and toneburst in overall peak-to-peak amplitude. As expected, normal-hearing participants did not exhibit hemispheric differences when comparing C3-A2 and C4-A1 peak-to-peak amplitudes demonstrating symmetric auditory brain function. However, chirp-evoked MLRs will require further study to determine its usefulness in clinical practice. American Academy of Audiology.

Hearing aid effectiveness after aural rehabilitation - individual versus group (HEARING) trial: RCT design and baseline characteristics

PubMed Central

2009-01-01

Background Hearing impairment is the most common body system disability in veterans. In 2008, nearly 520,000 veterans had a disability for hearing loss through the Department of Veterans Affairs (VA). Changes in eligibility for hearing aid services, along with the aging population, contributed to a greater than 300% increase in the number of hearing aids dispensed from 1996 to 2006. In 2006, the VA committed to having no wait times for patient visits while providing quality clinically-appropriate care. One approach to achieving this goal is the use of group visits as an alternative to individual visits. We sought to determine: 1) if group hearing aid fitting and follow-up visits were at least as effective as individual visits, and 2) whether group visits lead to cost savings through the six month period after the hearing aid fitting. We describe the rationale, design, and characteristics of the baseline cohort of the first randomized clinical trial to study the impact of group versus individual hearing aid fitting and follow-up visits. Methods Participants were recruited from the VA Puget Sound Health Care System Audiology Clinic. Eligible patients had no previous hearing aid use and monaural or binaural air-conduction hearing aids were ordered at the evaluation visit. Participants were randomized to receive the hearing aid fitting and the hearing aid follow-up in an individual or group visit. The primary outcomes were hearing-related function, measured with the first module of the Effectiveness of Aural Rehabilitation (Inner EAR), and hearing aid adherence. We tracked the total cost of planned and unplanned audiology visits over the 6-month interval after the hearing aid fitting. Discussion A cohort of 659 participants was randomized to receive group or individual hearing aid fitting and follow-up visits. Baseline demographic and self-reported health status and hearing-related measures were evenly distributed across the treatment arms. Outcomes after the 6-month follow-up period are needed to determine if group visits were as least as good as those for individual visits and will be reported in subsequent publication.

Tinnitus is a common condition, especially prevalent among military Veterans. Progressive Tinnitus Management (PTM) is an interdisciplinary, structured, stepped-care approach to providing clinical services, including teaching coping skills, to people bothered by tinnitus. PTM has been shown to be effective at reducing functional distress, but implementation of the intervention outside of a research setting has not been studied, even though dissemination is underway within the Veterans Health Administration (VHA) system in the United States. This study was designed to address a gap in knowledge of PTM clinical implementation to date, with a focus on factors facilitating or hindering implementation in VHA audiology and mental health clinic contexts, and whether implementing sites had developed intervention adaptations. Qualitative interviews were conducted with 21 audiology and mental health clinicians and service chiefs across a regional service network. Interviews were transcribed and coded using a hybrid inductive-deductive analytic approach guided by existing implementation research frameworks and then iteratively developed for emergent themes. PTM prioritization was rare overall, with providers across disciplines challenged by lack of capacity for implementation, but with differences by discipline in challenges to prioritization. Where PTM was prioritized and delivered, this was facilitated by perception of unique value, provider's own experience of tinnitus, observation/experience with PTM delivery, intervention fit with provider's skills, and an environment with supportive leadership and adaptive reserve. PTM was frequently adapted to local contexts to address delivery challenges and diversify patient options. Adaptations included shifting from group to individual formats, reducing or combining sessions, and employing novel therapeutic approaches. Existing adaptations highlight the need to better understand mechanisms underlying PTM's effectiveness, and research on the impact of adaptations on patient outcomes is an important next step. Prioritization of PTM is a key barrier to the scale up and spread of this evidence-based intervention. Developing clinician champions may facilitate dissemination, especially if accompanied by signals of systemic prioritization. Novel approaches exposing clinicians and administrators to PTM may identify and develop clinical champions. Acknowledging the potential for PTM adaptations may make delivery more feasible in the context of existing system constraints and priorities.

Tinnitus service provision in the United Kingdom has been investigated from the healthcare provider's perspective demonstrating considerable regional variation particularly regarding availability of psychological treatments. An audiological-based tinnitus service, however, was reportedly available for all tinnitus patients in the UK. The aim of the current study was to define and evaluate nationwide tinnitus healthcare services from the patients' viewpoint. Secondary analyses were performed on data from a 33-item questionnaire provided by the British Tinnitus Association. The questionnaire had been distributed via email and social media. Responses from 937 participants who had or had previously experienced tinnitus were analysed. All but one person had at some time consulted their GP. About one in five received medication in primary care. The majority were referred to secondary care, generally an ENT surgeon or audiovestibular physician; some were referred directly to audiological services. In secondary care the majority underwent audiometric testing and over half underwent MRI scanning. Drugs were prescribed less frequently in secondary care. About one third of patients were referred onwards from diagnostic services in secondary care to receive therapeutic interventions for tinnitus. Therapy was generally delivered by an audiologist or hearing therapist. Just under two fifths of people discharged from secondary care returned to their GP, with most returning within one year. Over a third of this group were re-referred to secondary care. Few patients saw a psychologist (2.6%) though some psychological treatments were delivered by appropriately trained audiologists. Negative counselling from healthcare professionals in both primary and secondary care settings was reported. Although the UK has developed a national service for patients with tinnitus many people find it difficult to access, being blocked at the primary care level or after secondary care diagnostic services. Many of those discharged from secondary care return to their GP within a short space of time and are re-referred to secondary care creating an unsatisfactory and expensive revolving-door pattern of healthcare. Despite psychological treatment modalities having the best evidence base for successful tinnitus management, only a minority of tinnitus patients ever get to meet a psychologist.

The present research deals with the clinical and social problems present during linguistic and cognitive development of deaf children. Currently, the development of Theory of Mind represents an important research field in deafness studies. These international studies highlighted a significant alteration in the development of Theory of Mind in deaf children compared to normal hearing children, especially in cases of congenital or preverbal hearing loss. In particular, the research focuses on the skills of deaf children in recognising emotions and desires, through both perceptive and cognitive methods, by evaluation of psycho-cognitive skills of children with severe hearing loss using a set of questions to be administered to hearing loss patients. The experiment was performed on a group composed of 10 children (5 males and 5 females) aged 4 to 9 years and 54 to 108 months, affected by bilateral congenital hearing loss (severe to total), or hearing loss that developed in preverbal children the year before entering elementary school, or during the fourth year of elementary school. The selection criteria were based on: audiologic evaluation, neuro-psychological tests administered to assess general, cognitive as well as praxis and perceptive abilities, and clinical observations performed to assess psychopathology using tests that assess development of both visual perceptive (Coloured Progressive Matrices) and graphic representational abilities (Test of Human Figure Drawings and the Family Drawing Test). The instrument "cognitive" was the "Deaf Children Series", arranged by us, that consists of a mental status examination (MSE) that evaluates: level of cognitive (knowledge-related) ability, emotional mood, and speech and thought patterns at the time of evaluation. Deaf children show a reduced responsiveness to the expressions of sadness on the perceptive side. Through the test, we observed a psychodynamic defense mechanism considering perceptive understanding performance. On the contrary, in normal hearing children, the emotion 'fear' is the most difficult to identify. Deaf children seem to be more susceptible to recognition of visual emotions. Furthermore, deaf children present significant problem-solving skills and emotional recognition skills, possibly as a result of their hearing impairment. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.

Objective: Many tinnitus patients complain about difficulties regarding speech comprehension. In spite of the high clinical relevance little is known about underlying mechanisms and predisposing factors. Here, we performed an exploratory investigation in a large sample of tinnitus patients to (1) estimate the prevalence of speech comprehension difficulties among tinnitus patients, to (2) compare subjective reports of speech comprehension difficulties with behavioral measurements in a standardized speech comprehension test and to (3) explore underlying mechanisms by analyzing the relationship between speech comprehension difficulties and peripheral hearing function (pure tone audiogram), as well as with co-morbid hyperacusis as a central auditory processing disorder. Subjects and Methods: Speech comprehension was assessed in 361 tinnitus patients presenting between 07/2012 and 08/2014 at the Interdisciplinary Tinnitus Clinic at the University of Regensburg. The assessment included standard audiological assessments (pure tone audiometry, tinnitus pitch, and loudness matching), the Goettingen sentence test (in quiet) for speech audiometric evaluation, two questions about hyperacusis, and two questions about speech comprehension in quiet and noisy environments (“How would you rate your ability to understand speech?”; “How would you rate your ability to follow a conversation when multiple people are speaking simultaneously?”). Results: Subjectively-reported speech comprehension deficits are frequent among tinnitus patients, especially in noisy environments (cocktail party situation). 74.2% of all investigated patients showed disturbed speech comprehension (indicated by values above 21.5 dB SPL in the Goettingen sentence test). Subjective speech comprehension complaints (both for general and in noisy environment) were correlated with hearing level and with audiologically-assessed speech comprehension ability. In contrast, co-morbid hyperacusis was only correlated with speech comprehension difficulties in noisy environments, but not with speech comprehension difficulties in general. Conclusion: Speech comprehension deficits are frequent among tinnitus patients. Whereas speech comprehension deficits in quiet environments are primarily due to peripheral hearing loss, speech comprehension deficits in noisy environments are related to both peripheral hearing loss and dysfunctional central auditory processing. Disturbed speech comprehension in noisy environments might be modulated by a central inhibitory deficit. In addition, attentional and cognitive aspects may play a role. PMID:28018209

Specific language impairment is a relatively common developmental condition in which a child fails to develop language at the typical rate despite normal general intellectual abilities, adequate exposure to language, and in the absence of hearing impairments, or neurological or psychiatric disorders. There is much controversy about the extent to which the auditory processing deficits are important in the genesis specific language impairment. The objective of this paper is to assess the higher cortical functions in children with specific language impairment, through assessing neurophysiological changes in order to correlate the results with the clinical picture of the patients to choose the proper rehabilitation training program. This study was carried out on 40 children diagnosed to have specific language impairment and 20 normal children as a control group. All children were subjected to the assessment protocol applied in Kasr El-Aini hospital. They were also subjected to a language test (receptive, expressive and total language items), the audio-vocal items of Illinois test of psycholinguistic (auditory reception, auditory association, verbal expression, grammatical closure, auditory sequential memory and sound blending) as well as audiological assessment that included peripheral audiological and P300 amplitude and latency assessment. The results revealed a highly significant difference in P300 amplitude and latency between specific language impairment group and control group. There is also strong correlations between P300 latency and the grammatical closure, auditory sequential memory and sound blending, while significant correlation between the P300 amplitude and auditory association and verbal expression. Children with specific language impairment, in spite of the normal peripheral hearing, have evidence of cognitive and central auditory processing defects as evidenced by P300 auditory event related potential in the form of prolonged latency which indicate a slow rate of processing and defective memory as evidenced by small amplitude. These findings affect cognitive and language development in specific language impairment children and should be considered during planning the intervention program.

Chronic diseases can act as an accelerating factor in the auditory system degeneration. Studies on the association between presbycusis and diabetes mellitus and systemic arterial hypertension have shown controversial conclusions. To compare the initial audiometry (A1) with a subsequent audiometry (A2) performed after a 3 to 4-year interval in a population of elderly patients with diabetes mellitus and/or systemic arterial hypertension, to verify whether hearing loss in these groups is more accelerated when compared to controls without these clinical conditions. 100 elderly individuals participated in this study. For the auditory threshold assessment, a previous complete audiological evaluation (A1) and a new audiological evaluation (A2) performed 3-4 years after the first one was utilized. The participants were divided into four groups: 20 individuals in the diabetes mellitus group, 20 individuals in the systemic arterial hypertension group, 20 individuals in the diabetes mellitus/systemic arterial hypertension group and 40 individuals in the control group, matching them with each study group, according to age and gender. ANOVA and Kruskal-Wallis statistical tests were used, with a significance level set at 0.05. When comparing the mean annual increase in the auditory thresholds of the A1 with the A2 assessment, considering each study group and its respective control, it can be observed that there was no statistically significant difference for any of the frequencies for the diabetes mellitus group; for the systemic arterial hypertension group, significant differences were observed after 4kHz. For the diabetes mellitus and systemic arterial hypertension group, significant differences were observed at the frequencies of 500, 2kHz, 3kHz and 8kHz. It was observed that the systemic arterial hypertension group showed the greatest decrease in auditory thresholds in the studied segment when compared to the other groups, suggesting that among the three studied conditions, hypertension seems to have the greatest influence on hearing.

Contrast sensitivity test and conventional and high frequency audiometry: information beyond that required to prescribe lenses and headsets

In Optometry and in Audiology, the routine tests to prescribe correction lenses and headsets are respectively the visual acuity test (the first chart with letters was developed by Snellen in 1862) and conventional pure tone audiometry (the first audiometer with electrical current was devised by Hartmann in 1878). At present there are psychophysical non invasive tests that, besides evaluating visual and auditory performance globally and even in cases catalogued as normal according to routine tests, supply early information regarding diseases such as diabetes, hypertension, renal failure, cardiovascular problems, etc. Concerning Optometry, one of these tests is the achromatic luminance contrast sensitivity test (introduced by Schade in 1956). Concerning Audiology, one of these tests is high frequency pure tone audiometry (introduced a few decades ago) which yields information relative to pathologies affecting the basal cochlea and complements data resulting from conventional audiometry. These utilities of the contrast sensitivity test and of pure tone audiometry derive from the facts that Fourier components constitute the basis to synthesize stimuli present at the entrance of the visual and auditory systems; that these systems responses depend on frequencies and that the patient's psychophysical state affects frequency processing. The frequency of interest in the former test is the effective spatial frequency (inverse of the angle subtended at the eye by a cycle of a sinusoidal grating and measured in cycles/degree) and, in the latter, the temporal frequency (measured in cycles/sec). Both tests have similar duration and consist in determining the patient's threshold (corresponding to the inverse multiplicative of the contrast or to the inverse additive of the sound intensity level) for each harmonic stimulus present at the system entrance (sinusoidal grating or pure tone sound). In this article the frequencies, standard normality curves and abnormal threshold shifts inherent to the contrast sensitivity test (which for simplicity could be termed "visionmetry") and to pure tone audiometry (also termed auditory sensitivity test) are analyzed with the purpose of contributing to divulge their ability to supply early information associated to pathologies not solely related to the visual and auditory systems respectively.

Short- and long-term effects of the modified swedish version of the Active Communication Education (ACE) program for adults with hearing loss.

In Sweden, there is a lack of evidence-based rehabilitation programs for hearing loss. The Active Communication Education program (ACE) has successfully been used in Australia and was translated and evaluated in a Swedish pilot study. The pilot study included 23 participants (age 87 yr). No statistically significant effects were found, but the qualitative assessments indicated that this population found the program to be beneficial. The participants requested more focus on the psychosocial consequences of hearing loss, and the modules in the original ACE program were modified. The aim of this study was to explore the effects of a modified Swedish version of the ACE program in a population aged 39-82 yr old. Design was a between-group and within-group intervention study. The participants were recruited from the hearing health clinic in Linköping during 2010 and 2012. A total of 73 participants agreed to undergo the ACE, and 67 (92%) completed three or more sessions. The ACE program consists of five weekly 2 hr group sessions with 6 to 10 participants per group. The outcomes were measured before initiation of the program, 3 wk after program completion, and 6 mo after program completion and included communication strategy use, activity and participation, health-related quality of life, and anxiety and depression. In addition, outcomes were measured after program completion using the International Outcome Inventory-Alternative Interventions, a modified version of the Client Oriented Scale of Improvement, and qualitative feedback was obtained about the response to the program and actions taken as a result of participation. The treatment effects were examined using repeated-measures analyses of variance. Statistically significant effects were found for communication strategy use, activity and participation, and psychosocial well-being. Statistically significant effects were found for gender and degree of hearing loss, indicating that women and those with mild hearing loss significantly improved communication strategies. It is suggested that the program be implemented as part of regular audiological rehabilitation and offered in an early stage of rehabilitation. American Academy of Audiology.

Real-ear-to-coupler difference (RECD) measurements are used for the purposes of estimating degree and configuration of hearing loss (in dB SPL ear canal) and predicting hearing aid output from coupler-based measures. Accurate measurements of hearing threshold, derivation of hearing aid fitting targets, and predictions of hearing aid output in the ear canal assume consistent matching of RECD coupling procedure (i.e., foam tip or earmold) with that used during assessment and in verification of the hearing aid fitting. When there is a mismatch between these coupling procedures, errors are introduced. The goal of this study was to quantify the systematic difference in measured RECD values obtained when using a foam tip versus an earmold with various tube lengths. Assuming that systematic errors exist, the second goal was to investigate the use of a foam tip to earmold correction for the purposes of improving fitting accuracy when mismatched RECD coupling conditions occur (e.g., foam tip at assessment, earmold at verification). Eighteen adults and 17 children (age range: 3-127 mo) participated in this study. Data were obtained using simulated ears of various volumes and earmold tubing lengths and from patients using their own earmolds. Derived RECD values based on simulated ear measurements were compared with RECD values obtained for adult and pediatric ears for foam tip and earmold coupling. Results indicate that differences between foam tip and earmold RECDs are consistent across test ears for adults and children which support the development of a correction between foam tip and earmold couplings for RECDs that can be applied across individuals. The foam tip to earmold correction values developed in this study can be used to provide improved estimations of earmold RECDs. This may support better accuracy in acoustic transforms related to transforming thresholds and/or hearing aid coupler responses to ear canal sound pressure level for the purposes of fitting behind-the-ear hearing aids.

The aim of this study was to introduce a new grafting technique in tympanoplasty that involves use of a boomerang-shaped chondroperichondrial graft (BSCPG). The anatomical and functional results were evaluated. A new tympanoplasty with boomerang-shaped chondroperichondrial graft (TwBSCPG) technique was used in 99 chronic otitis media patients with central or marginal perforation of the tympanic membrane and a normal middle ear mucosa. All 99 patients received chondroperichondrial cartilage grafts with a boomerang-shaped cartilage island left at the anterior and inferior parts. Postoperative follow-ups were conducted at months 1, 6, and 12. Preoperative and postoperative audiological examinations were performed and air-bone gaps were calculated according to the pure-tone averages (PTAs) of the patients. In the preoperative period, most (83.8%) air-bone gaps were ≥ 16 dB; after operating using the TwBSCPG technique, the air-bone gaps decreased to 0-10 dB in most patients (77.8%). In the TwBSCPG patients, the mean preoperative air-bone gap was 22.02 ± 6.74 dB SPL. Postoperatively, the mean postoperative air-bone gap was 8.70 ± 5.74 dB SPL. The TwBSCPG technique therefore decreased the postoperative air-bone gap compared to that preoperatively (p = 0.000, z = -8.645). At the 1-month follow-up, there were six graft perforations and one graft retraction. At the 6-month follow-up, there were nine graft perforations and three graft retractions. At 12 months, there were seven graft perforations and four graft retractions. During the first year after the boomerang tympanoplasty surgery, graft lateralization was not detected in any patient. Retractions were grade 1 according to the Sade classification and were localized to the postero-superior quadrant of the tympanic membrane. The TwBSCPG technique has benefits with respect to postoperative anatomical and audiological results. It prevents perforation of the tympanic membrane at the anterior quadrant and avoids graft lateralization due to placement of the graft under the manubrium mallei. Given these benefits, the TwBSCPG technique seems to be a good alternative for grafting in tympanoplasties.

Many of the world's population have hearing loss in one ear; current statistics indicate that up to 10% of the population may be affected. Although the detrimental impact of bilateral hearing loss, hearing aids, and cochlear implants upon music appreciation is well recognized, studies on the influence of single-sided deafness (SSD) are sparse. We sought to investigate whether a single-sided hearing loss can cause problems with music appreciation, despite normal hearing in the other ear. A tailored questionnaire was used to investigate music appreciation for those with SSD. We performed a retrospective survey of a population of 51 adults from a University Hospital Audiology Department SSD clinic. SSD was predominantly adult-onset sensorineural hearing loss, caused by a variety of etiologies. Analyses were performed to assess for statistical differences between groups, for example, comparing music appreciation before and after the onset of SSD, or before and after receiving hearing aid(s). Results demonstrated that a proportion of the population experienced significant changes to the way music sounded; music was found to sound more unnatural (75%), unpleasant (71%), and indistinct (81%) than before hearing loss. Music was reported to lack the perceptual qualities of stereo sound, and to be confounded by distortion effects and tinnitus. Such changes manifested in an altered music appreciation, with 44% of participants listening to music less often, 71% of participants enjoying music less, and 46% of participants reporting that music played a lesser role in their lives than pre-SSD. Negative effects surrounding social occasions with music were revealed, along with a strong preference for limiting background music. Hearing aids were not found to significantly ameliorate these effects. Results could be explained in part through considerations of psychoacoustic changes intrinsic to an asymmetric hearing loss and impaired auditory scene analysis. Given the prevalence of music and its capacity to influence an individual's well-being, results here present strong indications that the potential effects of SSD on music appreciation should be considered in a clinical context; an investigation into relevant rehabilitation techniques may prove valuable.

Individual Differences in Effectiveness of Cochlear Implants in Children Who Are Prelingually Deaf: New Process Measures of Performance

PubMed Central

Pisoni, David B.; Cleary, Miranda; Geers, Ann E.; Tobey, Emily A.

2011-01-01

The efficacy of cochlear implants in children who are deaf has been firmly established in the literature. However, the effectiveness of cochlear implants varies widely and is influenced by demographic and experiential factors. Several key findings suggest new directions for research on central auditory factors that underlie the effectiveness of cochlear implants. First, enormous individual differences have been observed in both adults and children on a wide range of audiological outcome measures. Some patients show large increases in speech perception scores after implantation, whereas others display only modest gains on standardized tests. Second, age of implantation and length of deafness affect all outcome measures. Children implanted at younger ages do better than children implanted at older ages, and children who have been deaf for shorter periods do better than children who have been deaf for longer periods. Third, communication mode affects outcome measures. Children from “oral-only” environments do much better on standardized tests that assess phonological processing skills than children who use Total Communication. Fourth, at the present time there are no preimplant predictors of outcome performance in young children. The underlying perceptual, cognitive, and linguistic abilities and skills emerge after implantation and improve over time. Finally, there are no significant differences in audiological outcome measures among current implant devices or processing strategies. This finding suggests that the major source of variance in outcome measures lies in the neural and cognitive information processing operations that the user applies to the signal provided by the implant. Taken together, this overall pattern of results suggests that higher-level central processes such as perception, attention, learning, and memory may play important roles in explaining the large individual differences observed among users of cochlear implants. Investigations of the content and flow of information in the central nervous system and interactions between sensory input and stored knowledge may provide important new insights into the basis of individual differences. Knowledge about the underlying basis of individual differences may also help in developing new intervention strategies to improve the effectiveness of cochlear implants in children who show relatively poor development of oral/aural language skills.

Measuring Temporal Resolution (Release of Masking) with a Hughson-Westlake Up-Down Instead of a Békèsy-Tracking Procedure.

Rhebergen, Koenraad S; van Esch, Thamar E M; Dreschler, Wouter A

2015-06-01

A temporal resolution test in addition to the pure-tone audiogram may be of great clinical interest because of its relevance in speech perception and expected relevance in hearing aid fitting. Larsby and Arlinger developed an appropriate clinical test, but this test uses a Békèsy-tracking procedure for estimating masked thresholds in stationary and interrupted noise to assess release of masking (RoM) for temporal resolution. Generally the Hughson-Westlake up-down procedure is used in the clinic to measure the pure-tone thresholds in quiet. A uniform approach will facilitate clinical application and might be appropriate for RoM measurements as well. Because there is no golden standard for measuring the RoM in the clinic, we examine in the present study the Hughson-Westlake up-down procedure to measure the RoM and compare the results with the Békèsy-tracking procedure. The purpose of the current study was to examine the differences between a Békèsy-tracking procedure and the Hughson-Westlake up-down procedure for estimating masked thresholds in stationary and interrupted noise to assess RoM. RoM is assessed in eight normal-hearing (NH) and ten hearing-impaired (HI) listeners through both methods. Results from both methods are compared with each other and with predicted thresholds from a model. Wilcoxon signed-rank tests, paired t tests. Some differences between the two methods were found. We used a model to quantify the results of the two measurement procedures. The results of the Hughson-Westlake procedure were clearly better in agreement with the model than the results of the Békèsy-tracking procedure. Furthermore, the Békèsy-tracking procedure showed more spread in the results of the NH listeners than the Hughson-Westlake procedure. The Hughson-Westlake procedure seems to be an applicable alternative for measuring RoM for temporal resolution in the clinical audiological practice. American Academy of Audiology.

Objective: Many tinnitus patients complain about difficulties regarding speech comprehension. In spite of the high clinical relevance little is known about underlying mechanisms and predisposing factors. Here, we performed an exploratory investigation in a large sample of tinnitus patients to (1) estimate the prevalence of speech comprehension difficulties among tinnitus patients, to (2) compare subjective reports of speech comprehension difficulties with behavioral measurements in a standardized speech comprehension test and to (3) explore underlying mechanisms by analyzing the relationship between speech comprehension difficulties and peripheral hearing function (pure tone audiogram), as well as with co-morbid hyperacusis as a central auditory processing disorder. Subjects and Methods: Speech comprehension was assessed in 361 tinnitus patients presenting between 07/2012 and 08/2014 at the Interdisciplinary Tinnitus Clinic at the University of Regensburg. The assessment included standard audiological assessments (pure tone audiometry, tinnitus pitch, and loudness matching), the Goettingen sentence test (in quiet) for speech audiometric evaluation, two questions about hyperacusis, and two questions about speech comprehension in quiet and noisy environments ("How would you rate your ability to understand speech?"; "How would you rate your ability to follow a conversation when multiple people are speaking simultaneously?"). Results: Subjectively-reported speech comprehension deficits are frequent among tinnitus patients, especially in noisy environments (cocktail party situation). 74.2% of all investigated patients showed disturbed speech comprehension (indicated by values above 21.5 dB SPL in the Goettingen sentence test). Subjective speech comprehension complaints (both for general and in noisy environment) were correlated with hearing level and with audiologically-assessed speech comprehension ability. In contrast, co-morbid hyperacusis was only correlated with speech comprehension difficulties in noisy environments, but not with speech comprehension difficulties in general. Conclusion: Speech comprehension deficits are frequent among tinnitus patients. Whereas speech comprehension deficits in quiet environments are primarily due to peripheral hearing loss, speech comprehension deficits in noisy environments are related to both peripheral hearing loss and dysfunctional central auditory processing. Disturbed speech comprehension in noisy environments might be modulated by a central inhibitory deficit. In addition, attentional and cognitive aspects may play a role.

Cortical auditory evoked potentials in the assessment of auditory neuropathy: two case studies.

PubMed

Pearce, Wendy; Golding, Maryanne; Dillon, Harvey

2007-05-01

Infants with auditory neuropathy and possible hearing impairment are being identified at very young ages through the implementation of hearing screening programs. The diagnosis is commonly based on evidence of normal cochlear function but abnormal brainstem function. This lack of normal brainstem function is highly problematic when prescribing amplification in young infants because prescriptive formulae require the input of hearing thresholds that are normally estimated from auditory brainstem responses to tonal stimuli. Without this information, there is great uncertainty surrounding the final fitting. Cortical auditory evoked potentials may, however, still be evident and reliably recorded to speech stimuli presented at conversational levels. The case studies of two infants are presented that demonstrate how these higher order electrophysiological responses may be utilized in the audiological management of some infants with auditory neuropathy.

Auditorily-induced illusory self-motion: a review.

2009-10-01

The aim of this paper is to provide a first review of studies related to auditorily-induced self-motion (vection). These studies have been scarce and scattered over the years and over several research communities including clinical audiology, multisensory perception of self-motion and its neural correlates, ergonomics, and virtual reality. The reviewed studies provide evidence that auditorily-induced vection has behavioral, physiological and neural correlates. Although the sound contribution to self-motion perception appears to be weaker than the visual modality, specific acoustic cues appear to be instrumental for a number of domains including posture prosthesis, navigation in unusual gravitoinertial environments (in the air, in space, or underwater), non-visual navigation, and multisensory integration during self-motion. A number of open research questions are highlighted opening avenue for more active and systematic studies in this area.

Trends in cochlear implants.

2004-01-01

More than 60,000 people worldwide use cochlear implants as a means to restore functional hearing. Although individual performance variability is still high, an average implant user can talk on the phone in a quiet environment. Cochlear-implant research has also matured as a field, as evidenced by the exponential growth in both the patient population and scientific publication. The present report examines current issues related to audiologic, clinical, engineering, anatomic, and physiologic aspects of cochlear implants, focusing on their psychophysical, speech, music, and cognitive performance. This report also forecasts clinical and research trends related to presurgical evaluation, fitting protocols, signal processing, and postsurgical rehabilitation in cochlear implants. Finally, a future landscape in amplification is presented that requires a unique, yet complementary, contribution from hearing aids, middle ear implants, and cochlear implants to achieve a total solution to the entire spectrum of hearing loss treatment and management.

Inclusive education and personal development.

1999-01-01

Open-ended questionnaires covering mainstream educational experiences and personal development of deaf and hard-of-hearing adults were analyzed. Half of the 34 deaf and hard-of-hearing respondents altered self-labels based on changes in personal definitions rather than audiological changes. Supportive school environments and coping skills contributed to positive perceptions; nonsupportive school environments and being treated as 'different' were viewed negatively. Everyone valued contact with hearing peers. Contact with deaf peers depended on finding those with similar values. Identification with Deaf culture was nonexistent. Most noteworthy, 24 of 34 participants felt caught between the deaf and hearing worlds, indicating the need for niches in both. Implications for educators are that development of self-confidence and comfort with identity may be enhanced by validating the deafness dimension through opportunities for contact with deaf adults and positive relationships with both deaf and hearing peers.

Concise review of recent studies in vitiligo

Allam, Mohamed; Riad, Hassan

2013-01-01

Vitiligo is an acquired pigmentry disorder of the skin and mucous membranes which manifests as white macules and patches due to selective loss of melanocytes. Etiological hypotheses of vitiligo include genetic, immunological, neurohormonal, cytotoxic, biochemical, oxidative stress and newer theories of melanocytorrhagy and decreased melanocytes survival. There are several types of vitiligo which are usually diagnosed clinically and by using a Wood's lamp; also vitiligo may be associated with autoimmune diseases, audiological and ophthalmological findings or it can be a part of polyendocrinopathy syndromes. Several interventions are available for the treatment for vitiligo to stop disease progression and/or to attain repigmentation or even depigmentation. In this article, we will present an overall view of current standing of vitiligo research work especially in the etiological factors most notably the genetic components, also, types and associations and various and newer treatment modalities.

Hearing loss in Usher syndrome type II is nonprogressive.

Reisser, Christoph F V; Kimberling, William J; Otterstedde, Christian R

2002-12-01

Usher syndrome is an autosomal recessive disorder characterized by sensorineural hearing loss and progressive visual loss secondary to retinitis pigmentosa. In the literature, a possible progression of the moderate to severe hearing loss in Usher syndrome type II (Usher II) is controversial. We studied the development of the hearing loss of 125 patients with a clinical diagnosis of Usher syndrome type II intraindividually and interindividually by repeatedly performing complete audiological and neuro-otologic examinations. Our data show a very characteristic slope of the hearing curve in all Usher II patients and no clinically relevant progression of the hearing loss over up to 17 years. The subjective impression of a deterioration of the communicative abilities of Usher II patients must therefore be attributed to the progressive visual loss. The patients should be reassured that changes in their hearing abilities are unlikely and should be provided with optimally fitted modern hearing aids.

Lipreading in the prelingually deaf: what makes a skilled speechreader?

PubMed

Rodríguez Ortiz, Isabel de los Reyes

2008-11-01

Lipreading proficiency was investigated in a group of hearing-impaired people, all of them knowing Spanish Sign Language (SSL). The aim of this study was to establish the relationships between lipreading and some other variables (gender, intelligence, audiological variables, participants' education, parents' education, communication practices, intelligibility, use of SSL). The 32 participants were between 14 and 47 years of age. They all had sensorineural hearing losses (from severe to profound). The lipreading procedures comprised identification of words in isolation. The words selected for presentation in isolation were spoken by the same talker. Identification of words required participants to select their responses from set of four pictures appropriately labelled. Lipreading was significantly correlated with intelligence and intelligibility. Multiple regression analyses were used to obtain a prediction equation for the lipreading measures. As a result of this procedure, it is concluded that proficient deaf lipreaders are more intelligent and their oral speech was more comprehensible for others.

Albinism is an inherited abnormality of melanin synthesis with incidence of one per 20,000 births. Its clinical manifestations are related to the reduction or absence of pigmentation in the visual system and/or the skin and teguments. The clinical spectrum of Oculocutaneous Albinism (OCA) has four types ranging from OCA 1 - 4, of which OCA 1, A-1 is the most severe form. Partial cutaneous albinism which is a subtype of OCA is associated with systemic immunodeficiency disorders like Chediak Higashi (CHS), Griscelli (GS) and Hermansky-Pudlak (HPS) syndromes. A7 years boy was labeled initially as a case of Hermansky Pudlak syndrome at the age of 01 year. He as well as his 4 years old younger brother when examined in detail along with audiological investigations were diagnosed as a rare presentation of both Hermansky Pudlak and Waardenburg's syndrome.

To determine the prevalence and characteristics of hearing loss in Behçet syndrome. This study included 27 patients with Behçet syndrome and 35 sex-and age-matched controls. A complete audiological evaluation was performed. The average pure-tone audiograms from both groups showed a statistically significant hearing loss in the Behçet group. Sixteen patients (59.26%) showed some degrees of sensorineural hearing loss (SNHL), with the high-frequency type (4, 8, 10, and 12 kHz) being the most common pattern (93.75%). Hearing loss was the fourth most common manifestation. Although the patient's age, sex, and the duration of the disease were not related to hearing loss, there was a significant correlation between a negative pathergy test and hearing loss in patients with Behçet syndrome. We should consider audiovestibular involvement in Behçet syndrome as a common finding.

The impact of a family history of hearing problems on those with hearing difficulties themselves: an exploratory study.

2005-04-01

The objective of the study was to investigate the effects of a family history of hearing impairment on those people with the hearing impairment themselves. The subjects were 102 consecutive patients with a family history of hearing impairment, seen in an audiological rehabilitation clinic. Each was given an open-ended questionnaire asking whether such a family history had any effects on them and, if so, to list any effects. Results were qualitatively analysed. 57 subjects indicated effects. Of those listed, 57% were positive, 19% negative, and 24% neutral. The most common positive effects concerned realising the importance of hearing aids and early help-seeking. Common negative effects were concern for the future of themselves and their children. Neutral effects were a reported ignorance or denial of a family history. The results emphasize the importance of asking patients about any family history when planning their rehabilitative programme.

The sound pressure levels (SPLs) of common infant humidifiers were determined to identify the likely sound exposure to infants and young children. This primary investigative research study was completed at a tertiary-level academic medical center otolaryngology and audiology laboratory. Five commercially available humidifiers were obtained from brick-and-mortar infant supply stores. Sound levels were measured at 20-, 100-, and 150-cm distances at all available humidifier settings. Two of 5 (40%) humidifiers tested had SPL readings greater than the recommended hospital infant nursery levels (50 dB) at distances up to 100 cm. In this preliminary study, it was demonstrated that humidifiers marketed for infant nurseries may produce appreciably high decibel levels. Further characterization of the effect of humidifier design on SPLs and further elucidation of ambient sound levels associated with hearing risk are necessary before definitive conclusions and recommendations can be made. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

Computers are used increasingly in patient-clinician consultations. There is the potential for PC use to have an effect on the communication process. The aim of this preliminary study was to investigate patient opinion regarding the use of PC-based note taking during diagnostic vestibular assessments. We gave a simple four-item questionnaire to 100 consecutive patients attending for vestibular assessment at a secondary referral level primary care trust audiology service. Written responses to two of the questionnaire items were subject to an inductive thematic analysis. The questionnaire was acceptable to patients, none refused to complete it. Dominant themes identified suggest that patients do perceive consistent positive benefits from the use of PC-based note taking. This pilot study's short survey instrument is usable and may provide insights into patients' perceptions of computer use in a clinical setting.

Parents' communication decision for children with hearing loss: sources of information and influence.

2012-01-01

Choosing a method of communication for a child with hearing loss is a complex process that must occur early to prevent developmental consequences. Research shows that parents' decisions are influenced by professionals; parental attitudes and knowledge also may be influential. The present study investigated additional influences on parents' choices; data were collected via an online survey (N = 36). Results indicated no effects of parents' knowledge of development on their communication choices, but did indicate an effect of parents' values and priorities for their children. Further, parents who chose speech only received information from education or speech/audiology professionals more often. However, there were no group differences in sources parents cited as influential; all parents relied on their own judgment. Results suggest that parents internalize the opinions of professionals. Thus, accurate information from professionals is necessary for parents to make informed decisions about their children's communication.

Student values and preferences: what do they tell us about programme selection?

Allied health professionals are thought to acquire their orientation through professional socialization and education, but it is likely that they share similar values before being admitted to any educational programme. The results of a study involving occupational therapy, physical therapy, and speech pathology/audiology students (N = 276) support this contention. The Life Roles Inventory, Vocational Preference Inventory and a student information sheet were the instruments employed. Using discriminant analysis, the results demonstrate that although respondents endorse the same values, the level of that endorsement differs significantly between the three student groups. Similarly, the same Holland Code was generated for each group, but again the level of endorsement for the six primary scales varies in each case. The more allied health educators know about the values and preferences their students endorse, and how they seek to implement them, the better prepared educators should be to recruit, place, teach and counsel them.

Tinnitus in children: an uncommon symptom?

PubMed

Shetye, A; Kennedy, V

2010-08-01

Tinnitus in children is regarded as an uncommon problem rarely noted by general paediatricians. Its reported prevalence varies from 12% to 36% in children with normal hearing thresholds and up to 66% in children with hearing loss and approximately 3-10% of children have been reported troubled by tinnitus. Some children do not spontaneously complain of it, but may demonstrate behavioural problems at school and home. A careful history, in conjunction with clinical findings, should guide the appropriate management approach. Even very young children are able to provide insights into what troubles them allowing children's thoughts and fears regarding this symptom to be addressed. We review the available literature on the nature and impact of tinnitus and as guidelines for this do not exist, suggest a pragmatic approach to the management of tinnitus in children. Children with troublesome tinnitus, however, should be referred on to a paediatric audiology department for further investigation and management.

Animal experiments have shown that after specific nerve traumatization, neuromuscular electrostimulation (NMES) can promote nerve regeneration and reduce synkinesia without negatively interfering with normal regeneration processes. NMES is used routinely in physical rehabilitation medicine. This systematic literature search in the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, the DAHTA database, the Health Technology Assessment Database and MEDLINE or PubMed considered studies on the use of NMES in otorhinolaryngology that have been published in German or English. The search identified 180 studies. These were evaluated and relevant studies were included in the further evaluation. In the fields of otorhinolaryngology and phoniatry/paediatric audiology, clinical studies investigating the effects of NMES on facial and laryngeal paresis, as well as dysphonia and dysphagia have been carried out. The evidence collected to date is encouraging; particularly for the treatment of certain forms of dysphagia and laryngeal paresis.

Data mining (DM) is a technique used to discover pattern and knowledge from a big amount of data. It uses artificial intelligence, automatic learning, statistics, databases, etc. In this study, DM was successfully used as a predictive tool to assess disyllabic speech test performance in bilateral implanted patients with a success rate above 90%. 60 bilateral sequentially implanted adult patients were included in the study. The DM algorithms developed found correlations between unilateral medical records and Audiological test results and bilateral performance by establishing relevant variables based on two DM techniques: the classifier and the estimation. The nearest neighbor algorithm was implemented in the first case, and the linear regression in the second. The results showed that patients with unilateral disyllabic test results below 70% benefited the most from a bilateral implantation. Finally, it was observed that its benefits decrease as the inter-implant time increases.

To determine the long-term influence of organic mercurial intoxication on audiological and equilibrium findings, we followed up 36 patients neurotologically during 1980-1987 and 1991-2000 at Kido Hospital in Niigata. Typical findings were as follows: 1. In pure-tone audiometry, 24 of 72 ears (33%) showed slight hearing deterioration and 3 (4%) showed improvement. 2. Spontaneous nystagmus had disappeared in 5 patients (14%), but appeared in new 13 patients (36%). Positional nystagmus did not improve in any patient, and deteriorated in 11 (31%). 3. In optokinetic nystagmus (OKN) tests, especially in vertical OKN test showing significant deterioration (44%). 4. The caloric nystagmus test showed marked deterioration (47%). Body-equilibrium testing showed slight deterioration in 11 patients (31%) and improvement in 5 (14%). Neurotological findings thus varied widely among patients and we were concluded that these differences were caused both by duration of methyl mercury contamination and by aging factors in patients.

Alkaptonuria is an inborn error of metabolism. It is a multisystem disease with characteristic ENT manifestations. This paper reports, for the first time, the ENT findings in a cohort of alkaptonuria patients. Patients attending the National Centre for Alkaptonuria (Royal Liverpool and Broadgreen University Hospitals NHS Trust) underwent a full ENT assessment. Eighteen of the 20 patients (90 per cent) had an ENT sign or symptom. These included discolouration of the pinna, cerumen, nasal septum and pharynx. Discolouration of cerumen may occur before 30 years of age and may therefore be an important early clinical sign. Further audiological assessment of patients is needed to clarify if an association exists between alkaptonuria and hearing loss. Alkaptonuria is a condition that could present to the otolaryngologist. Successful early diagnosis and referral to a specialist centre is essential so that patients can be offered disease-modifying therapy.

Increasing evidence suggests children with Down syndrome do not receive recommended health care services. We retrospectively assessed adherence to the 2001 American Academy of Pediatrics health supervision guidelines for 124 children with Down syndrome. Cervical spine radiographs were completed for 94% of children, often preoperatively. Adherence to complete blood count recommendations was 55% (95% CI 44% to 66%); lower for males ( P = .01) and children with private medical insurance ( P = .04). Adherence to thyroid function recommendations was 61% (95% CI 54% to 67%); higher for children seen by a pediatrician ( P = .002) and with known thyroid disease ( P < .0001). Adherence to audiology and ophthalmology recommendations was 33% (95% CI 27% to 40%) and 43% (95% CI 37% to 50%), respectively. Adherence rates were higher for children referred to an otolaryngologist ( P = .0002) and with known eye disease ( P < .0001). Future efforts should identify barriers to care and improve adherence to recommended screening.

Hearing plays a vital role in the performance of a soldier and is important for speech processing. Noise-induced hearing loss is a significant impairment in the military and can affect combat performance. Military personnel are constantly exposed to high levels of noise and it is not surprising that noise induced hearing loss and tinnitus remain the second most prevalent service-connected disabilities. Much of the noise experienced by military personnel exceeds that of maximum protection achievable with double hearing protection. Unfortunately, unlike civilian personnel, military personnel have little option but to remain in noisy environments in order to complete specific tasks and missions. Use of hearing protection devices and follow-up audiological tests have become the mainstay of prevention of noise-induced hearing loss. This review focuses on sources of noise within the military, pathophysiology and management of patients with noise induced hearing loss.

In comparison with organic hearing loss, which is commonly reported, non-organic hearing loss is under-represented in the literature. The audiological results for 20 patients, aged between 6 and 17 years (mean 11.3), with psychogenic hearing disturbances were analysed prospectively. In 17 cases, the disturbance was bilateral and in three cases unilateral. In no case was the result of an objective hearing test exceptional, while a hearing threshold of between 30 and 100 dB was reported in single ear, pure-tone audiograms. In 12 cases, single ear speech audiograms were unexceptional. Suprathreshold tests, such as the dichotic discrimination test or the speech audiogram with noise disturbance, could lead to a clearer diagnosis in cases of severe psychogenic auditory impairment. In half of the patients, a conflict situation in the school or family was evident. After treatment for this conflict, hearing ability returned to normal. There was no improvement for six patients.

Trends in Cochlear Implants

More than 60,000 people worldwide use cochlear implants as a means to restore functional hearing. Although individual performance variability is still high, an average implant user can talk on the phone in a quiet environment. Cochlear-implant research has also matured as a field, as evidenced by the exponential growth in both the patient population and scientific publication. The present report examines current issues related to audiologic, clinical, engineering, anatomic, and physiologic aspects of cochlear implants, focusing on their psychophysical, speech, music, and cognitive performance. This report also forecasts clinical and research trends related to presurgical evaluation, fitting protocols, signal processing, and postsurgical rehabilitation in cochlear implants. Finally, a future landscape in amplification is presented that requires a unique, yet complementary, contribution from hearing aids, middle ear implants, and cochlear implants to achieve a total solution to the entire spectrum of hearing loss treatment and management.

2012-01-01

Treacher Collins syndrome (TCS) is a common genetic disorder with high penetrance and phenotypic variability. First and second branchial arches are affected in TCS, resulting in craniofacial and intraoral anomalies such as: severe convex facial profile; mid-face hypoplasia; microtia; eyelid colobomas; mandibular retrognathism; cleft palate; dental hypoplasia; heterotopic teeth; maxillary transverse hypoplasia; anterior open bite; and Angle Class II molar relationship. A high incidence of caries is also a typical finding in TCS patients. Nonetheless, even simple dental restorative procedures can be challenging in this patient population due to other associated medical conditions, such as: congenital heart defects; decreased oropharyngeal airways; hearing loss; and anxiety toward treatment. These patients often require a multidisciplinary treatment approach, including: audiology; speech and language pathology; otorhinolaryngology; general dentistry; orthodontics; oral and maxillofacial surgery; and plastic and reconstructive surgeries to improve facial appearance. This paper's purpose was to present a current understanding of Treacher Collins syndrome etiology, phenotype, and current treatment approaches.

Different etiologies are related to tinnitus including metabolic disorders (blood glucose and lipids). The aim of this study was compare tinnitus severity by self-report measures pre and post nutritional intervention, using the Tinnitus Handicap Inventory. Participants of this study were twenty one male and female subjects, with ages ranging from 40 to 82 years. Inclusion criteria involved the presence of tinnitus and metabolic disorder diagnosed by laboratory exams. All subjects were submitted to a nutritional intervention program. Audiological evaluation and the Tinnitus Handicap Inventory were applied pre and post intervention. When comparing the presence of tinnitus pre and post intervention, data analysis indicates statistical difference concerning tinnitus sensation--71.5% of the individuals referred less impact of tinnitus in daily activities. An important difference was observed concerning tinnitus influence in subject's life by self-report measures. A direct relation between tinnitus and metabolic disorders in cases related with this symptom was verified.

Cerebrospinal fluid genome counts were determined by quantitative real-time polymerase chain reaction from 121 children: 36 with Streptococcus pneumoniae and 85 with Haemophilus influenzae meningitis. To examine the interactions of genome count and to determine its prognostic importance, we projected the results against findings on admission and different outcomes. The genome count varied vastly in both meningitides ranging from 0 to 9,250,000/microL. The genome quantity was weakly associated with only some of the patient findings on admission. High counts predicted neurologic (odds ratio [OR]=1.36; 95% confidence interval [CI], 1.09-1.69; P=0.006 for 1 log increase) but not audiologic sequelae. They also predicted death in S .pneumoniae (OR=2.05; 95% CI, 1.08-3.87; P=0.03) but not in H. influenzae meningitis.

2003-04-01

Congenital aural atresia repair is difficult owing to unpredictable anatomy. Benefits may be gained from computer-aided surgery (CAS), but its exact role has yet to be clearly defined. This is a retrospective study of 18 patients with bony type C (Schuknecht classification) congenital atresia. In the first group (n = 9), repair was performed with CAS while in the second group (n = 9), similar intervention was applied without CAS. Intra- and post-operative clinical and audiological findings were compared. CAS computed tomography (CT) images correlated well with intra-operative findings giving the surgeon more security and reducing operative time by 25 minutes. In our estimation, CAS is valuable for type C congenital aural atresia repair. It serves as an educational tool and as a guide for the experienced surgeon in critical situations where anatomical landmarks are distorted and where access is limited.

Hearing loss is a major handicap in developing countries with paucity of trained audiologists and limited resources. In this pilot study trained community health workers were used to provide comprehensive hearing aid services in the community. One hundred and eleven patients were fitted with semi-digital hearing aid and were evaluated over a period of six months. They were assessed using self-report outcome measure APHAB. Results show that trained CHWs are effective in detecting disabling hearing loss and in providing HAs. APHAB can identify and pick up significant improvements in communication in daily activities and provides a realistic expectation of the benefits of a hearing aid. The model of using trained CHWs to provide rehabilitative services in audiology along with self-report outcome measures can be replicated in other developing countries. PMID:23724277

In South Africa, the current movement towards the inclusion of children with disabilities, including children with hearing loss, is likely to have far-reaching consequences for both teachers and learners. Undoubtedly, needs will arise from teachers during the transition, especially in the areas pertaining to the audiological and educational management of children with hearing loss. Therefore, a descriptive research design was developed comprising of a questionnaire survey followed by focus group interviews to determine teachers' needs. The questionnaire survey explored the needs of 664 teachers while focus group interviews were conducted with 19 teachers of children with hearing loss. Teachers were mostly from special schools as only a very small number of children are educated outside these establishments. Findings revealed that, although participants realised the importance of various aspects of development of the child with hearing loss, they generally did not realise the importance of receiving support from an educational audiologist.

SUMMARY Programmes for early childhood childhood hearing impairment identification allows to quickly start the appropriate hearing aid fitting and rehabilitation process; nevertheless, a large number of patients do not join the treatment program. The goal of this article is to present the results of a strategic review of the strengths, weaknesses, opportunities and threats connected with the audiologic/prosthetic/language follow-up process of children with bilateral permanent hearing impairment. Involving small children, the follow-up includes the involvement of specialised professionals of a multidisciplinary team and a complex and prolonged multi-faced management. Within the framework of the Italian Ministry of Health project CCM 2013 "Preventing Communication Disorders: a Regional Program for Early Identification, Intervention and Care of Hearing Impaired Children", the purpose of this analysis was to propose recommendations that can harmonise criteria for outcome evaluation and provide guidance on the most appropriate assessment methods to be used in the follow-up course of children with permanent hearing impairment.

2004-10-01

The Vibrant Soundbridge is a semi-implantable middle ear hearing device used in the rehabilitation of adults with sensorineural hearing loss. In order to evaluate the long-term effects of the implanted part of the device, audiological data from 39 patients implanted over several implant sites across France were collected and analyzed retrospectively. The mean follow-up time was 16 months; 25 patients had a follow-up period of over 1 year. Surgery was uneventful in all cases. The present study of the 39 implanted patients with a mid- to long-term follow-up found a statistically significant modification of hearing thresholds (pre- versus postoperative) for frequencies of 0.5 and 4 kHz. However, the shift of threshold was rather limited (2.79 and 3.34 dB, respectively), and this variation was not statistically different from the evolution of the opposite non-operated ear.

Autism spectrum disorders (ASD) are complex neuro-developmental disorders affecting children in their early age. The diagnosis of ASD relies on multidisciplinary investigations, in psychiatry, neurology, genetics, electrophysiology, neuro-imagery, audiology and ophthalmology. In order to support clinicians, researchers and public health decision makers, we designed an information system dedicated to ASD, called TEDIS. TEDIS was designed to manage systematic, exhaustive and continuous multi-centric patient data collection via secured Internet connections. In this paper, we present the security policy and security infrastructure we developed to protect ASD' patients' clinical data and patients' privacy. We tested our system on 359 ASD patient records in a local secured intranet environment and showed that the security system is functional, with a consistent, transparent and safe encrypting-decrypting behavior. It is ready for deployment in the nine ASD expert assessment centers in the Ile de France district.

The aim of this exploratory study was to describe audiologist communication behaviours during appointments for hearing device monitoring and management before and after participation in counselling skills training. The study used a longitudinal design with three assessment points over 6 months. The sample included 10 audiologists and audiology graduate students interacting in a professional setting with their clients. Audiologists reported improvement in their counselling skills from pre-training to follow-up, which was consistent with objective findings that audiologist relative speaking time decreased from pre-training to post-training as well as from pre-training to follow-up. Observer-rated scores of participants' counselling skills; however, yielded no significant differences across time. Some improvement was noted in audiologists' counselling behaviour following a 1-day communication skills workshop and continued learning support. It is evident; however, that further training, such as increased training and performance feedback, is needed to maintain and enhance audiologist progress in the various aspects of counselling.

The British Society of Audiology has produced clear guidelines as to how otoscopy should be undertaken; however, no nationally recognised guidelines exist for the wider clinical community. Images of otoscopy appear in many books, journals, magazines and websites. This study aimed to determine the rate of non-compliance with good practice in images of otoscopy, the seriousness of the breach, and whether this is more common in sites for professionals or the general public. Google Images was searched using the terms 'otoscopy' and 'ear examination'. A total of 200 images were identified and collated. The images were reviewed for compliance with good practice standards. Only 12.75 per cent of the images were graded as having no breach of good practice standards. Professional websites have a responsibility to show best practice. When choosing an image, the source of the image needs to be carefully considered.

The aims were to compare the genotype/phenotype relationship between USH3 mutations and the consequent hearing and vestibular phenotype; and to compare hearing loss (HL) progression between Usher syndrome types IB, IIA and USH3. Genetic, audiometric and vestibular examinations were performed in 28 subjects with USH3. Five different mutations in USH3 were identified. Severe HL was present from an early age (4 to 6 years) in 35% of subjects with USH3. Progression of HL begins in the first decade, and approximately 50% of subjects with USH3 become profoundly deaf by age 40. Various vestibular abnormalities were found in about half (10/22) of the tested subjects with USH3. Depending on the severity of HL, subjects with USH3 might be misdiagnosed as either Usher type IB or IIA. The results from this study can be used as discriminatory features in differential diagnosis of this syndrome.

Database for vertigo.

1995-03-01

An interactive database has been developed to assist the diagnostic procedure for vertigo and to store the data. The database offers a possibility to split and reunite the collected information when needed. It contains detailed information about a patient's history, symptoms, and findings in otoneurologic, audiologic, and imaging tests. The symptoms are classified into sets of questions on vertigo (including postural instability), hearing loss and tinnitus, and provoking factors. Confounding disorders are screened. The otoneurologic tests involve saccades, smooth pursuit, posturography, and a caloric test. In addition, findings from specific antibody tests, clinical neurotologic tests, magnetic resonance imaging, brain stem audiometry, and electrocochleography are included. The input information can be applied to workups for vertigo in an expert system called ONE. The database assists its user in that the input of information is easy. If not only can be used for diagnostic purposes but is also beneficial for research, and in combination with the expert system, it provides a tutorial guide for medical students.

The aim of the study was to determine audiological function at 14 years of age of very-low-birthweight (VLBW < or = 1500 g) children compared with a cohort of normal birthweight (NBW > 2499 g) children. Participants were consecutive surviving preterm children of birthweight < 1000 g born between 1977 and 1982 (n=86) and of birthweight 1000 to 1500 g born between 1980 and 1982 (n=124) and randomly selected NBW children born between 1981 and 1982 (n=60). Audiometric tests included pure tone audiometry, tympanometry, stapedius muscle reflexes, and measures of central auditory processing. Psychometric tests included measures of IQ, academic achievement, and behaviour. There were no significant differences in rates of hearing impairment, abnormal tympanograms, figure-ground problems, or digit recall between VLBW children and NBW control children. VLBW children had higher rates of some central auditory processing problems, which in turn were associated with poorer intellectual, academic, and behavioural progress.

This paper presents the results of a study aimed at quantifying the effects of jet source noise reduction, increases in aircraft lift, and reduced aircraft thrust on the take-off noise associated with supersonic civil transports. Supersonic jet noise sources are first described, and their frequency and directivity dependence are defined. The study utilizes NASA's Aircraft Noise Prediction Program in a parametric study to weigh the relative benefits of several approaches to low noise. The baseline aircraft concept used in these predictions is the AST-205-1 powered by GE21/J11-B14A scaled engines. Noise assessment is presented in terms of effective perceived noise levels at the FAA's centerline and sideline measuring locations for current subsonic aircraft, and in terms of audiologically perceived sound of people and other indirect effects. The results show that significant noise benefit can be achieved through proper understanding and utilization of all available approaches.

Hearing Aid Use and Mild Hearing Impairment: Learnings from Big Data.

Timmer, Barbra H B; Hickson, Louise; Launer, Stefan

2017-09-01

Previous research, mostly reliant on self-reports, has indicated that hearing aid (HA) use is related to the degree of hearing impairment (HI). No large-scale investigation of the relationship between data-logged HA use and HI has been conducted to date. This study aimed to investigate if objective measures of overall daily HA use and HA use in various listening environments are different for adults with mild HI compared to adults with moderate HI. This retrospective study used data extracted from a database of fitting appointments from an international group of HA providers. Only data from the participants' most recent fitting appointment were included in the final dataset. A total of 8,489 bilateral HA fittings of adults over the age of 18 yr, conducted between January 2013 and June 2014, were included. Participants were subsequently allocated to HI groups, based on British Society of Audiology and American Speech-Language-Hearing Association audiometric descriptors. Fitting data from participating HA providers were regularly transferred to a central server. The data, with all personal information except age and gender removed, contained participants' four-frequency average (at 500, 1000, 2000, and 4000 Hz) as well as information on HA characteristics and usage. Following data cleaning, bivariate and post hoc statistical analyses were conducted. The total sample of adults' average daily HA use was 8.52 hr (interquartile range [IQR] = 5.49-11.77) in the left ear and 8.51 hr (IQR = 5.49-11.72) in the right ear. With a few exceptions, there were no statistical differences between hours of HA use for participants with mild HI compared to those with moderate impairment. Across all mild and moderate HI groups, the most common overall HA usage was between 8 and 12 hr per day. Other factors such as age, gender, and HA style also showed no relationship to hours of use. HAs were used, on average, for 7 hr (IQR = 4.27-9.96) per day in quiet and 1 hr (IQR = 0.33-1.41) per day in noisy listening situations. Clinical populations with mild HI use HAs as frequently as those with a moderate HI. These findings support the recommendation of HAs for adults with milder degrees of HI.

Familial auditory neuropathy.

2003-09-01

Auditory neuropathy is a sensorineural hearing disorder characterized by absent or abnormal auditory brainstem responses and normal cochlear outer hair cell function as measured by otoacoustic emission recordings. Many risk factors are thought to be involved in its etiology and pathophysiology. Four Chinese pedigrees with familial auditory neuropathy were presented to demonstrate involvement of genetic factors in the etiology of auditory neuropathy. Probands of the above-mentioned pedigrees, who had been diagnosed with auditory neuropathy, were evaluated and followed in the Department of Otolaryngology-Head and Neck Surgery, China People Liberation Army General Hospital (Beijing, China). Their family members were studied, and the pedigree maps established. History of illness, physical examination, pure-tone audiometry, acoustic reflex, auditory brainstem responses, and transient evoked and distortion-product otoacoustic emissions were obtained from members of these families. Some subjects received vestibular caloric testing, computed tomography scan of the temporal bone, and electrocardiography to exclude other possible neuropathic disorders. In most affected patients, hearing loss of various degrees and speech discrimination difficulties started at 10 to 16 years of age. Their audiological evaluation showed absence of acoustic reflex and auditory brainstem responses. As expected in auditory neuropathy, these patients exhibited near-normal cochlear outer hair cell function as shown in distortion product otoacoustic emission recordings. Pure-tone audiometry revealed hearing loss ranging from mild to profound in these patients. Different inheritance patterns were observed in the four families. In Pedigree I, 7 male patients were identified among 43 family members, exhibiting an X-linked recessive pattern. Affected brothers were found in Pedigrees II and III, whereas in pedigree IV, two sisters were affected. All the patients were otherwise normal without evidence of peripheral neuropathy at the time of writing. Patients with characteristics of nonsyndromic hereditary auditory neuropathy were identified in one large and three smaller Chinese families. Pedigree analysis suggested an X-linked, recessive hereditary pattern in one pedigree and autosomal recessive inheritances in the other three pedigrees. The phenotypes in the study were typical of auditory neuropathy; they were transmitted in different inheritance patterns, indicating clinical and genetic heterogeneity of this disorder. The observed inheritance and clinical audiological findings are different from those previously described for nonsyndromic low-frequency sensorineural hearing loss. This information should facilitate future molecular linkage analyses and positional cloning for the relative genes contributing to auditory neuropathy.

Subjective and objective outcomes from new BiCROS technology in a veteran sample.

Patients with single-sided deafness (SSD), where one ear has an unaidable hearing loss and the other ear has normal or aidable hearing, often complain of difficulties understanding speech and localizing sound sources, and report a higher self-perceived hearing disability. Patients with SSD may benefit from using contralateral routing of signal (CROS) or bilateral contralateral routing of the signal (BiCROS) amplification. Dissatisfaction of previously available (Bi)CROS devices has been reported, such as, interfering transmissions, low-fidelity sound quality, poor "user-friendly" set-up, and a bulky and cosmetically cumbersome appearance. Recent advances in hearing aid technology have improved (Bi)CROS hearing aids; however, these devices have not been experimentally evaluated. We hypothesized that newer technology with reports of improved digital signal processing, wireless transmission, and physical design would be as good, or better than, our participants' previous-generation BiCROS systems. A within-subjects, pretest-posttest design was executed. Thirty-nine veterans (one female, 38 males; mean age = 74 yr, range = 49-85 yr) from the Audiology Section of the Bay Pines Veterans Affair Healthcare System participated. All participants were previously experienced BiCROS hearing aid users with varying degrees of sensorinerual hearing impairment in their better ear. Participants were provided at least 4 wk of consistent use with the new BiCROS. DATA COLLECTION AND ANALYSES: Participants completed three research visits. At Visit 1, with their previous BiCROS, and at Visit 3, with their new BiCROS, the following objective and subjective measures were obtained: (1) soundfield speech-in-noise testing using the Words-In-Noise (WIN) test; (2) speech, spatial, and qualities of the hearing scale (SSQ) questionnaire; (3) selected questions from the MarkeTrak questionnaire; and, (4) three open-ended questions. Data were analyzed using parametric and nonparametric statistics. Overall, the objective (WIN) and subjective (SSQ, MarkeTrak, and open-ended questions) measures indicated that the new BiCROS provided better outcomes than the previous BiCROS system. In addition, an overlap of favorable results was seen across measures. Of the 39 participants, 95% reported improvements with the new BiCROS and chose to utilize the device regularly. The favorable objective and subjective outcomes indicate that the new BiCROS system is as good, or better than, what was previously utilized by our sample of veterans. American Academy of Audiology.

Bacterial meningitis (BM) is the primary etiology of acquired sensorineural hearing loss (SNHL) in children and may compromise language development. Since the 1990 s, cochlear implants (CIs) have become part of the management of children with profound SNHL with encouraging results. The aim of this study was to analyze the audiophonological performance of children before and after cochlear implantation for SNHL following bacterial meningitis. Retrospective study of all children fitted with CIs for bilateral severe to profound SNHL after bacterial meningitis in the Robert-Debré pediatric ENT department between August 1990 and March 2009. Audiophonological performance was assessed using the APCEI profile. Of the 283 children receiving implants during that period, 16 children (6%; 6 boys, 10 girls) underwent CI implantation after bacterial meningitis (Streptococcus pneumoniae in 8 cases, Neisseria meningitidis in 2 cases, and Haemophilus influenzae in 4 cases). The mean time from meningitis to SNHL was 8.3 months (median, 1.5 months; range, 1 day to 13 years). The mean time from meningitis to cochlear implantation was 2 years and 3 months (median, 7 months; range, 1 month to 13 years 3 months). Twelve children (75%) presented partial cochlear and/or vestibular ossification on presurgical CT scan. Three children received bilateral implants. Thirteen children (81%) developed early SNHL in the first 3 months, whereas 3 children developed SNHL more than 10 months after meningitis. As for the benefits of cochlear implantation, 11 children presented near to normal intelligibility and optimal use of their cochlear implant; 5 children presented partial benefits due to neurological sequelae (1), a long delay before implantation (1), technical problems (2), or a social problem in relation to low socioeconomic status (1). After bacterial meningitis, audiological evaluation must be made carefully during the first 3 months to detect early SNHL, but SNHL may also develop several years later. In case of profound SNHL and a modified signal of the labyrinth on the MRI, cochlear implantation must be performed without delay before cochlear and/or vestibular ossification. Cochlear implantation is an effective technique with good long-term audiologic results. The coexistence of neurological lesions may compromise the results, but it should not contraindicate a cochlear implantation. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

The decision to fit one or two hearing aids in individuals with binaural hearing loss has been debated for years. Although some 78% of U.S. hearing aid fittings are binaural (Kochkin , 2010), Walden and Walden (2005) presented data showing that 82% (23 of 28 patients) of their sample obtained significantly better speech recognition in noise scores when wearing one hearing aid as opposed to two. To conduct two new experiments to fuel the monaural/binaural debate. The first experiment was a replication of Walden and Walden (2005), whereas the second experiment examined the use of binaural cues to improve speech recognition in noise. A repeated measures experimental design. Twenty veterans (aged 59-85 yr), with mild to moderately severe binaurally symmetrical hearing loss who wore binaural hearing aids were recruited from the Audiology Department at the Bay Pines VA Healthcare System. Experiment 1 followed the procedures of the Walden and Walden study, where signal-to-noise ratio (SNR) loss was measured using the Quick Speech-in-Noise (QuickSIN) test on participants who were aided with their current hearing aids. Signal and noise were presented in the sound booth at 0° azimuth under five test conditions: (1) right ear aided, (2) left ear aided, (3) both ears aided, (4) right ear aided, left ear plugged, and (5) unaided. The opposite ear in (1) and (2) was left open. In Experiment 2, binaural Knowles Electronics Manikin for Acoustic Research (KEMAR) manikin recordings made in Lou Malnati's pizza restaurant during a busy period provided a typical real-world noise, while prerecorded target sentences were presented through a small loudspeaker located in front of the KEMAR manikin. Subjects listened to the resulting binaural recordings through insert earphones under the following four conditions: (1) binaural, (2) diotic, (3) monaural left, and (4) monaural right. Results of repeated measures ANOVAs demonstrated that the best speech recognition in noise performance was obtained by most participants with both ears aided in Experiment 1 and in the binaural condition in Experiment 2. In both experiments, only 20% of our subjects did better in noise with a single ear, roughly similar to the earlier Jerger et al (1993) finding that 8-10% of elderly hearing aid users preferred one hearing aid.

To evaluate independent etiologic factor associated with sensorineural hearing loss (SNHL) in newborn at risk; to study the role of their interaction especially in NICU infants who present often multiple risk factors for SNHL. The main risk factors for SNHL reported by JCIH 2007 were evaluated on 508 infant at risk ranging from 4 to 20 weeks of life, transferred to the Audiology Department of Palermo from the main births centers of Western Sicily. After a global audiological assessment, performed with TEOAE, tympanometry and ABR, the prevalence and the effect of risk factors was statistically studied through univariate and multivariate analysis on the total population (normal and deaf subjects). Fifty-one infants (10.03%) were diagnosed with SNHL (45 bilateral and 6 monolateral) with a mean hearing threshold of 87.39 ± 28.25 dB HL; from logistic regression analysis family history of hearing impairment (HI) and TORCH infections resulted independent significant risk factors (P<0.00001 and P=0.024 respectively). High SNHL percentages were evidenced also in NICU babies, due to the various pathologies and risk factors presented by these infants, and among newborns who suffered from hyperbilirubinemia requiring exchange transfusion (11.97% and 9.52% respectively). Craniofacial abnormalities (CFA) and syndromes associated to HI showed an important relationship (P<0.00001) with conductive hearing loss (CHL). Multiple regression analysis of the variation in SNHL among NICU infants evidenced an increased risk for SNHL of 21.24% and of 19.33% respectively in preterm infants and in case of hyperbilirubinemia if respiratory distress is concomitant with these risk factors. It was also observed an higher risk of SNHL (99.66%) in case of coexistence of prematurity and hyperbilirubinemia. Finally among infants with very low birth weight (VLBW) it was evidenced a statistically difference between the mean weight of SNHL infants respect to NHL newborns (P=0.048). The high SNHL prevalence (10.03%) in our cohort underlines how infants at risk are more susceptible to suffer from SNHL; in particular NICU newborns have a 33% greater chance of developing SNHL, because of the presence of multiple risk factors (or=1.33) and their interaction. As the number of coexisting risk factors increases, the prevalence of SNHL also increases (r(2)=0.93). Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

The purpose of this study was to assess audiologists' perceptions of ethics and moral climate in the workplace. The Ethics Environmental Questionnaire (EEQ) was sent out to all audiologists registered with the professional body Audiology Australia. Participants were also invited to undertake a semi-structured interview. A total of 301 audiologists completed the questionnaire. Eight of these participants also agreed to complete the interview. The overall mean on the EEQ was approximately equivalent to that of a positive ethical environment, with the exception of those working in adult rehabilitation settings who scored significantly poorer. Scores were significantly associated with state and age. Qualitative analysis from the interviews found that sales pressure from employers was the dominant cause for concern amongst the group. For those working in adult rehabilitation, moral distress is most likely to occur as the result of conflicting goals between the organisation and the audiologist. There is a need to regulate the practice at an organisational as well as individual level to ensure the focus remains on ethical practice.

To investigate detailed clinical features of a Chinese pedigree with Waardenburg syndrome type 2. Members of this pedigree were interviewed to identify personal or family medical histories of hearing loss, the use of aminoglycosides, and other clinical abnormalities by filling questionnaire. The audiological and other clinical evaluations of the proband and other members of this family were conducted, including pure-tone audiometry, immittance and auditory brain-stem response and ophthalmological, dermatologic, hair, temporal bone CT examinations. This family is categorized as Waardenburg syndrome type 2 according to its clinical features. It's an autosomal dominant disorder with incomplete penetrance. The clinical features varied greatly among family members and characterized by sensorineural hearing loss, heterochromia irides, freckle on the face and premature gray hair. Hearing loss can be unilateral or bilateral, congenital or late onset in this family. This Chinese family has some unique clinical features comparing with the international diagnostic criteria for Waardenburg syndrome. This study may provide some evidences to amend the diagnostic criteria for Waardenburg syndrome in Chinese population.

The Vibrant Soundbridge offers an excellent audiologic rehabilitation for toddlers with microtia and atresia. It provides direct stimulation of the cochlea and straightforward adaption to the given anatomical structures. The 'posterior atresia incision' preserves the physical integrity of the tissue layers around the ear remnant, which is essential for an aesthetic auricular reconstruction. Patients with bilateral aural atresia require immediate auditory stimulation to ensure normal speech development. We present an operative technique that allows safe restoration of hearing before aesthetic reconstruction. A 6-year-old boy presented with bilateral microtia and osseous atresia. A hairline incision was performed through all layers and was followed by a subperiostal preparation towards the atresia plane. The fused malleus-incus-complex was removed and the transducer was crimped to the stapes suprastructure on both sides. Speech performance is nearly normal in both quiet and noise conditions. The surgery did not affect the tissues that are important for the later ear reconstruction.

Spontaneous nystagmus in benign paroxysmal positional vertigo: is it a new sign?

PubMed

2013-01-01

Benign Paroxysmal Positional Vertigo (BPPV) is a condition that indicates a benign inner ear disorder. It is generally believed that BPPV is due to the dislodged otoconial particles from otolith organs and unusual collection of them within any of semicircular canals or even in all three semicircular canals. Although the typical features of nystagmus in BPPV have been well-studied, very few studies (just four articles) have highlighted the presence of spontaneous nystagmus in BPPV recently. During the past 10 years, 2850 patients have been examined at the audiology unit of our department, and 254 patients have received diagnoses of BPPV but recently 2 patients presented with BPPV and spontaneous nystagmus, a new symptom that has been never observed in our clinical records. We herein describe this rare symptom in 2 case of BPPV. A 50-year-old woman with BPPV who showed an 18 degree spontaneous nystagmus treated with Epley maneuver and a 53-year-old man with 3 degree spontaneous nystagmus.

The fit between journals and theses.

PubMed

Black, J W; Kricos, P B; Ptacek, P H; Hyman, M

1978-12-01

The titles of a substantial sample of articles related to speech pathology and audiology over a period of 21 years were catalogued under one or more of 10 categories, e.g., normal audition, defective phonation, and the like. The titles of theses and dissertations in this field of six universities of Ohio over the same period were also catalogued. The articles appeared in 17 journals. The journals were treated as seven groups of "related" journals. The total output of journals was stable over the period studied; a "group" of journals tended to be consistent with itself over successive 3-year periods; the seven groups of journals tended to be unique, and not to replicate each other. The topics treated in the journals were accepted as a criterion for contemporaneousness. The student output of the universities varied in contemporaneousness from one school to another, ranging upward to r = 0.98 (10 categories). The overall correlation between the student and the journal outputs was r = 0.79.

The aim of this study was to analyze the findings on Cortical Auditory Evoked Potentials in children with cochlear implant through a systematic literature review. After formulation of research question and search of studies in four data bases with the following descriptors: electrophysiology (eletrofisiologia), cochlear implantation (implante coclear), child (criança), neuronal plasticity (plasticidade neuronal) and audiology (audiologia), were selected articles (original and complete) published between 2002 and 2013 in Brazilian Portuguese or English. A total of 208 studies were found; however, only 13 contemplated the established criteria and were further analyzed; was made data extraction for analysis of methodology and content of the studies. The results described suggest rapid changes in P1 component of Cortical Auditory Evoked Potentials in children with cochlear implants. Although there are few studies on the theme, cochlear implant has been shown to produce effective changes in central auditory path ways especially in children implanted before 3 years and 6 months of age.

Impact of OSHA final rule--recording hearing loss: an analysis of an industrial audiometric dataset.

The 2003 Occupational Safety and Health Administration (OSHA) Occupational Injury and Illness Recording and Reporting Final Rule changed the definition of recordable work-related hearing loss. We performed a study of the Alcoa Inc. audiometric database to evaluate the impact of this new rule. The 2003 rule increased the rate of potentially recordable hearing loss events from 0.2% to 1.6% per year. A total of 68.6% of potentially recordable cases had American Academy of Audiology/American Medical Association (AAO/AMA) hearing impairment at the time of recordability. On average, recordable loss occurred after onset of impairment, whereas the non-age-corrected 10-dB standard threshold shift (STS) usually preceded impairment. The OSHA Final Rule will significantly increase recordable cases of occupational hearing loss. The new case definition is usually accompanied by AAO/AMA hearing impairment. Other, more sensitive metrics should therefore be used for early detection and prevention of hearing loss.

Identification of impaired hearing in early childhood.

PubMed Central

Wong, D; Shah, C P

1979-01-01

Although the incidence of congenital deafness is high, routine neonatal screening for this problem is not practised, and early identification of congenital or early acquired deafness is relatively rare. Delaying therapy until a child is 3 or more years old severely limits speech development, language acquisition and learning. The commonest causes of delay in diagnosis are the refusal of physicians to listen to the parents' observations, their failure to screen children for hearing and speech problems, and their reluctance to arrange prompt referral for audiologic assessment. Diagnostic delay occurs even though half the children who have impaired hearing are known to be at increased risk. A plea is made for the setting up of a register of infants known to be at risk for impaired hearing. First-contact physicians should be alert to the possibility of hearing problems, particularly in children at high risk. Screening methods for use by nonspecialist practitioners are outlined.

2018-05-01

In many instances of hearing loss, audiological improvement can be made via direct excitation of a temporal bone (i.e., bone conduction). In order to design better and more efficient devices, the macro-mechanics of the bone conduction hearing pathway must be better understood. Based on previous empirical work, numerical models are useful. In this work, we present results of a time-domain Fluid Structure Interaction model that describes stimulation of the bone conduction pathway. The cochlea was modelled as uncoiled and consisted of an oval window, a round window, a basilar membrane and a helicotrema. In order to monitor pressure waves in the perilymph, the fluid was considered compressible. The excitation, in form of sinusoidal velocity, was applied to the cochlea bony walls. The system was excited in three perpendicular directions: along the basilar membrane, perpendicularly to the membrane and transversely to the membrane. The numerical simulation examined which stimulation direction maximally excited the basilar membrane, the pressure distributions for each excitation direction, and the associated mechanics.

We conducted a retrospective study to compare poststapedectomy hearing gain in study-eligible patients who had received a Teflon (fluoroplastic ASTM F 754) prosthesis (study group; n = 76) with hearing gain achieved in a matched group (by age, sex, and degree of hypoacusis) of patients who had received a Schuknecht-type wire/Teflon prosthesis (control group; n = 70). All procedures had been performed by the authors at our institution between Jan. 2, 1994, and Dec. 31, 1997. Airway averages at low, medium, and high frequencies were estimated on the basis ofpre- and postoperative audiologic evaluations, as were total air-bone gaps at 7 frequencies between 125 and 8, 000 Hz. We found that the study group achieved a significantly greater degree of hearing gain at 125 and 250 Hz and significantly better closure of the air-bone gap at 250, 500, 1,000, 2,000, and 4,000 Hz. The hearing outcomes among patients in the study group were excellent.

Delayed Immunomodulatory Effect of Cow Milk-Free Diet in Ménière's Disease.

Since 1930, dietary modification has been proposed as adjunct treatment in Ménière's disease (MD) with different and controversial results. We report the case of a 42-year-old female suffering from definite MD and intermittent seasonal allergic rhino-conjunctivitis because it highlights the importance of evaluating the different combinations of defined causative elements in an atopic patient with MD. An immunological and audiological evaluation was performed, including pure-tone, speech, and immittance audiometry; glycerol dehydration test; bithermal caloric testing; video head impulse test; cervical vestibular evoked myogenic potentials; static posturography; and Dizziness Handicap Inventory questionnaire. A milk-free diet was crucial to relief from MD symptoms and a cow's milk challenge test was able to evoke them but vestibukar symptoms persist. The effect of dietary modification was evident only after specific immunotherapies against other allergens. This highlights the importance of evaluating different combinations of defined causative elements in the allergic treatment of MD.

[Hearing and balance in metabolic bone diseases].

Zatoński, Tomasz; Temporale, Hanna; Krecicki, Tomasz

There are reports that hearing loss is one of the clinical manifestations of metabolic bone diseases. Demineralization can lead to a reduction in ossicular mass. Paget's disease can reveal loss of mineral density of the cochlear bone. Ear bone remodeling in osteoporosis is similar to the changes in otosclerosis. Moreover, osteoporosis, osteogenesis imperfecta and otosclerosis have a similar genetic mechanism. According to some researchers osteopenia and osteoporosis may well be associated with idiopathic benign positional vertigo (BPV). Dysfunction of the organ of hearing and balance in patients with renal insufficiency may be due to disturbances in calcium phosphate balance and renal osteodystrophy in the course of the disease. Proving the presence of hearing loss in patients with metabolic bone diseases may lead to determining the new indications for bone densitometry in some patients with hearing impairment. Furthermore, audiological examination in patients with osteoporosis may be important because of the impact of hearing loss on prognosis for patients with metabolic bone diseases.

Ring versus 'Mercedes-Benz' cartilage-perichondrium graft tympanoplasty in management of pars tensa cholesteatoma.

To compare anatomical and audiological outcomes of ring versus 'Mercedes-Benz' cartilage-perichondrium graft tympanoplasty in patients with pars tensa cholesteatoma. Prospective clinical study. Otolaryngology department, Tanta University Hospital, Egypt. Over three years, 60 ears in 60 patients underwent surgery for either sinus or tensa retraction cholesteatoma, reconstructed using either a ring-shaped (30 ears) or Mercedes-Benz symbol shaped (30 ears) cartilage-perichondrium graft, with at least two years' follow up. Post-operative drum perforation and retraction, cholesteatoma residue and recurrence, middle-ear effusion, and hearing acuity were monitored. Anatomical outcomes were equivalent in both groups, but slightly better in the Mercedes group. Hearing improved significantly in both groups (pre- vs post-operative results), but significantly more so in the ring group. Within-group hearing outcomes were unaffected by cholesteatoma type or tympanoplasty type. The Mercedes-Benz technique may be superior to the ring technique in preventing neodrum retraction. However, the ring graft technique had better hearing outcomes, perhaps due to its more physiological design.
