Full Text Available Objective: This paper investigates the correlation and contact points between entrepreneurship as a discipline and the profession of audiology. The research focuses on specific areas of entrepreneurship (e.g. innovation as an entrepreneurial skill and the impact it has on audiology private practices as key role players in the biotechnology industry. Design: This study used a two-stage research design comprising of an exploratory study and a formal study to survey the entrepreneurial and business skills of audiologists as entrepreneurs in private practice. Findings: The findings describe severe deficiencies - specifically the business and entrepreneurial skill sets of the professional audiologist as an entrepreneur. The mind-set of the audiologist is not that of an entrepreneur, but rather of a small business owner. A lack of self-confidence to be creative, take risks, and identify new opportunities or innovate in terms of products, process and services was found. Audiologists are not necessarily concerned about the creation of employment, or the growth and profitability of their practices. Autonomy and security are the primary objectives of most practice owners. Keywords: Innovation, Entrepreneurs, Women Entrepreneurs, Entrepreneurship, Audiology, Biotechnology

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.

2018-04-01

Patient-centred communication (PCC) is an essential skill for effective healthcare provision and is accepted as a core competency in medicine and allied health. In audiology, recent studies have shown that audiologists rarely display PCC in adult hearing interactions. This highlights a need to investigate how PCC is taught and learnt in audiology. There is a paucity of studies on PCC in audiology education. The aim of this study is to examine educator perceptions of teaching PCC, including barriers and facilitators, in Australian graduate audiology programmes. Semi-structured interviews were conducted with audiology educators responsible for communication training. Interview transcripts were analysed using qualitative content analysis. Nine participants, including programme coordinators and key teaching staff from all six Australian audiology programmes participated in the study. PCC education was found to be influenced by four emerging themes: professional culture and values, contextual factors, knowledge and understanding of PCC and individual factors. These results provide an insight into the competing agendas involved in implementing PCC education in both the university and clinical component of audiology programmes. The findings can play a role in refining and building the evidence-base for teaching and facilitating patient-centred audiological care in future audiologists.

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.

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.

2015-09-01

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. 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. 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. This browser-server-based comprehensive tele-audiology offers a flexible platform to expand hearing services to traditionally underserved groups.

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.

Ng, Stella L; Bartlett, Doreen J; Lucy, S Deborah

2013-05-01

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

2011-07-01

Full Text Available Abstract Background In the UK, audiology services deliver the majority of tinnitus patient care, but not all patients experience the same level of service. In 2009, the Department of Health released a Good Practice Guide to inform commissioners about key aspects of a quality tinnitus service in order to promote equity of tinnitus patient care in UK primary care, audiology, and in specialist multi-disciplinary centres. The purpose of the present research was to evaluate utilisation and opinions on pathways for the referral of tinnitus patients to and from English Audiology Departments. Methods We surveyed all audiology staff engaged in providing tinnitus services across England. A 36-item questionnaire was mailed to 351 clinicians in all 163 National Health Service (NHS Trusts identified as having a tinnitus service. 138 clinicians responded. The results presented here describe experiences and opinions of the current patient pathways to and from the audiology tinnitus service. Results The most common referral pathway was from general practice to a hospital-based Ear, Nose & Throat department and from there to a hospital-based audiology department (64%. Respondents considered the NHS tinnitus referral process to be generally effective (67%, but expressed needs for improving GP referral and patients' access to services. 'Open access' to the audiology clinic was rarely an option for patients (9%, nor was the opportunity to access specialist counselling provided by clinical psychology (35%. To decrease the number of inappropriate referrals, 40% of respondents called for greater awareness by referrers about the audiology tinnitus service. Conclusions Respondents in the present survey were generally satisfied with the tinnitus referral system. However, they highlighted some potential targets for service improvement including 1] faster and more appropriate referral from GPs, to be achieved through education on tinnitus referral criteria, 2] improved

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.

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.

Full Text Available The CD-ROM "Voice Assessment: Speech-Language Pathology and Audiology & Medicine" was developed as a teaching tool for people interested in the production of the spoken or sung human voice. Its content comprises several subjects concerning the anatomy and physiology of spoken and sung voice. A careful assessment becomes necessary in order to ensure the effectiveness of teaching and learning educational materials, whether related to education or health, within the proposal of education mediated by technology. OBJECTIVE: This study aimed to evaluate the efficacy of the Virtual Man Project's CD-ROM "Voice Assessment: Speech-Language Pathology and Audiology & Medicine", as a self-learning material, in two different populations: Speech-Language Pathology and Audiology students and Lyrical Singing students. The participants were instructed to study the CD-ROM during 1 month and answer two questionnaires: one before and another one after studying the CD-ROM. The quantitative results were compared statistically by the Student's t-test at a significance level of 5%. RESULTS: Seventeen out of the 28 students who completed the study, were Speech-Language Pathology and Audiology students, while 11 were Lyrical Singing students (dropout rate of 44%. Comparison of the answers to the questionnaires before and after studying the CD-ROM showed a statistically significant increase of the scores for the questionnaire applied after studying the CD-ROM for both Speech-Language Pathology and Audiology and Lyrical Singing students, with p<0.001 and p<0.004, respectively. There was also a statistically significant difference in all topics of this questionnaire for both groups of students. CONCLUSION: The results concerning the evaluation of the Speech-Language Pathology and Audiology and Lyrical Singing students' knowledge before and after learning from the CD-ROM allowed concluding that the participants made significant improvement in their knowledge of the proposed

Kim, Gungu; Kim, Gibbeum; Na, Wondo

2016-01-01

This brief communication introduced a systematic way to find a professional audiology clinic developed for patients and professionals by the American Academy of Audiology, American Speech-Language-Hearing Association, and Healthy Hearing. Patients can access each organization's website to find professionals and/or clinics based on criteria such as location, hours, special areas, types of service, reviews and rating by previous patients, and kinds of insurance accepted. Such a system may protect the patients from information overload, guarantee accurate information, and help them find themselves professional audiologists who can assist them. We expect professional organizations to adopt this system as soon as possible and link hearing-impaired patients with professional audiologists in Korea. PMID:27626086

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

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

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

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.

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.

Audiological Rehabilitation for Facilitating Hearing Aid Use: A Review.

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.

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.

Audiological results with Baha in conductive and mixed hearing loss.

The level of improvement in the audiological results of Baha(®) users mainly depends on the patient's preoperative hearing thresholds and the type of Baha sound processor used. This investigation shows correlations between the preoperative hearing threshold and postoperative aided thresholds and audiological results in speech understanding in quiet of 84 Baha users with unilateral conductive hearing loss, bilateral conductive hearing loss and bilateral mixed hearing loss. Secondly, speech understanding in noise of 26 Baha users with different Baha sound processors (Compact, Divino, and BP100) is investigated. Linear regression between aided sound field thresholds and bone conduction (BC) thresholds of the better ear shows highest correlation coefficients and the steepest slope. Differences between better BC thresholds and aided sound field thresholds are smallest for mid-frequencies (1 and 2 kHz) and become larger at 0.5 and 4 kHz. For Baha users, the gain in speech recognition in quiet can be expected to lie in the order of magnitude of the gain in their hearing threshold. Compared to its predecessor sound processors Baha(®) Compact and Baha(®) Divino, Baha(®) BP100 improves speech understanding in noise significantly by +0.9 to +4.6 dB signal-to-noise ratio, depending on the setting and the use of directional microphone. For Baha users with unilateral and bilateral conductive hearing loss and bilateral mixed hearing loss, audiological results in aided sound field thresholds can be estimated with the better BC hearing threshold. The benefit in speech understanding in quiet can be expected to be similar to the gain in their sound field hearing threshold. The most recent technology of Baha sound processor improves speech understanding in noise by an order of magnitude that is well perceived by users and which can be very useful in everyday life.

Effective clinical communication is pivotal to the provision of quality hearing health care. To date, audiology students reportedly felt ill-prepared when counseling patients about their hearing impairment, yet there is a paucity of studies exploring how clinical communication is taught and learned in audiology programs. Thus, the aims of the study were (a) to explore final year audiology students' perspectives of their own clinical communication skills during an in-house university clinical placement and (b) to explore students' perceptions of their clinical communication education. Using a qualitative description approach, students were asked to coview their filmed clinical encounter using video reflexivity during a semistructured interview on clinical communication education. Fifteen final year graduate audiology students from The University of Melbourne, Australia, participated in the study. The interviews were audio-recorded and analyzed thematically. The overarching themes of striving to be patient-centered, assessment shapes behavior, and power relations emerged from students' reflection of their own clinical encounter. In addition, the theme what students want described the perceived teaching methods that assisted students' clinical communication practices. The findings of this study highlight the challenges that students perceived during their clinical placement as they strive to enact a patient-centered interaction. An assessment rubric that incorporates communication skills can provide greater opportunities for feedback and self-reflection. Additionally, clinical communication education that adopts experiential learning and is longitudinally integrated into the curriculum can further reinforce students' communication learning needs.

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

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.

Demographic and audiological factors as predictors of hearing handicap

2006-01-01

Full Text Available INTRODUCTION Currently available evidence reveals comparatively few studies of psychological effects of hearing impairments, in spite of the fact that clinicians have for a long time been aware of a connection between the acquired hearing impairment and mental disorders. They are focused on the investigation of dysfunction in general. Thus, three domains of the auditory imbalance may be distinguished: disorder, disability and handicap. 'Handicap', according to the definition of the World Health Organization, is a hindrance in an individual that results from an impairment or disability and represents psychological response of the individual to the impairment. OBJECTIVE Validation of acquired hearing impairment as a risk factor of psychical disorders as well as an analysis of relation of some demographic factors (sex, age, education and audiological factors (degree and duration of the impairment with the frequency of hearing handicap. METHOD MMPI-201 has been applied in 60 subjects affected with otosclerosis, potential candidates for stapedectomy, before and after the surgery. RESULTS Individuals with acquired hearing impairment manifest more frequent disorders of psychical functioning in comparison with general population, while demographic and audiometric parameters did not correlate with acquired hearing handicap. CONCLUSION It may be assumed that the very recognition of demographic and audio-logical factors can not help much in the understanding of the psychological stress associated with hearing impairment.

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. [Preparation for this presentation was supported, in part, by a K24 career development award from NIDCD.

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.

Trauma-associated tinnitus: audiological, demographic and clinical characteristics.

Directory of Open Access Journals (Sweden)

Peter M Kreuzer

Full Text Available BACKGROUND: Tinnitus can result from different etiologies. Frequently, patients report the development of tinnitus after traumatic injuries. However, to which extent this specific etiologic factor plays a role for the phenomenology of tinnitus is still incompletely understood. Additionally, it remains a matter of debate whether the etiology of tinnitus constitutes a relevant criterion for defining tinnitus subtypes. OBJECTIVE: By investigating a worldwide sample of tinnitus patients derived from the Tinnitus Research Initiative (TRI Database, we aimed to identify differences in demographic, clinical and audiological characteristics between tinnitus patients with and without preceding trauma. MATERIALS: A total of 1,604 patients were investigated. Assessment included demographic data, tinnitus related clinical data, audiological data, the Tinnitus Handicap Inventory, the Tinnitus Questionnaire, the Beck Depression Inventory, various numeric tinnitus rating scales, and the World Health Organisation Quality of Life Scale (WHOQoL. RESULTS: Our data clearly indicate differences between tinnitus patients with and without trauma at tinnitus onset. Patients suffering from trauma-associated tinnitus suffer from a higher mental burden than tinnitus patients presenting with phantom perceptions based on other or unknown etiologic factors. This is especially the case for patients with whiplash and head trauma. Patients with posttraumatic noise-related tinnitus experience more frequently hyperacousis, were younger, had longer tinnitus duration, and were more frequently of male gender. CONCLUSIONS: Trauma before tinnitus onset seems to represent a relevant criterion for subtypization of tinnitus. Patients with posttraumatic tinnitus may require specific diagnostic and therapeutic management. A more systematic and - at best - standardized assessment for hearing related sequelae of trauma is needed for a better understanding of the underlying pathophysiology and

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.

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

To evaluate the clinical features of audiologic impairment and its relationship with the nasal, vestibular, and rheumatologic profile in a cohort of patients with eosinophilic granulomatosis with polyangiitis (EGPA), formerly named Churg-Strauss syndrome. Prospective cross-sectional study. Thirty-nine patients with EGPA, considered controlled according to the Birmingham Vasculitis Activity Score and the Vasculitis Damage Index, underwent a complete audiologic evalutaion with otomicroscopy, impedance audiometry, speech audiometry, and auditory brainstem responses; rhinologic evaluation was made by means of fiberoptic endoscopy and nasal cytology; the clinical evaluation was completed with analysis of the facial function and, in patients with referred vertigo, with videonystagmography (VNG). Data were compared to the rheumatologic profile (eosinophil count, antineutrophil cytoplasmic antibodies status). Thirty-four of 39 patients fulfilled the inclusion criteria. Of those, 18 (52, 8%) were affected by variable degrees of hearing loss (sensorineural hearing loss [SNHL]) in four cases (11, 8%), mixed sensorineural and conductive hearing loss in two (5, 9%), presbycusis in six (17, 6%), and otitis media with effusion (OME) in six (17, 6%). Vestibular impairment was represented by benign paroxysmal positional vertigo and unspecific dizziness in three (8, 8%) and four cases (11, 8%), respectively, all with normal VNG. Ear involvement was statistically related to the EGPA vasculitic pattern and independent from the nasal impairment, cytology, and duration of nasal symptoms. No facial palsy was registered. In our experience, the largest in the existing literature, the otological involvement in EGPA is common and may occur variably as SNHL or OME. Otological involvement occurs early in the course of the disease process, but is nonspecific in making the diagnosis of EGPA. Its recognition is therefore fundamental. 4.

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.

Anatomical Changes and Audiological Profile in Branchio-oto-renal Syndrome: A Literature Review

Lindau, Tâmara Andrade

2014-01-01

Full Text Available Introduction Branchio-oto-renal (BOR syndrome is an autosomal-dominant genetic condition with high penetrance and variable expressivity, with an estimated prevalence of 1 in 40,000. Approximately 40% of the patients with the syndrome have mutations in the gene EYA1, located at chromosomal region 8q13.3, and 5% have mutations in the gene SIX5 in chromosome region 19q13. The phenotype of this syndrome is characterized by preauricular fistulas; structural malformations of the external, middle, and inner ears; branchial fistulas; renal disorders; cleft palate; and variable type and degree of hearing loss. Aim Hearing loss is part of BOR syndrome phenotype. The aim of this study was to present a literature review on the anatomical aspects and audiological profile of BOR syndrome. Data Synthesis Thirty-four studies were selected for analysis. Some aspects when specifying the phenotype of BOR syndrome are controversial, especially those issues related to the audiological profile in which there was variability on auditory standard, hearing loss progression, and type and degree of the hearing loss. Mixed loss was the most common type of hearing loss among the studies; however, there was no consensus among studies regarding the degree of the hearing loss.

Conclusion: We found varying degrees of otologic and audiologic abnormalities among the TS in ethnic Chinese population. About one-half of the patients had recurrent OM, which was more likely to be associated with CHL in early life. Therefore, regular surveillance, early diagnosis, and the initiation of appropriate treatment are crucial in improving the hearing and speech in children with TS as well as in preventing short- and long-term associated complications.

Various types of laser, microdrill, and perforator are effectively used in the surgical treatment of otosclerosis. However, they have certain disadvantages along with advantages. The aim of this study was to evaluate the effects of carbon dioxide (CO2) laser and perforator stapedotomy techniques on audiological outcomes and postoperative vestibular functions via videonystagmography (VNG). This prospective and randomized clinical study was conducted in an academic tertiary medical center. Sixty-nine patients diagnosed with otosclerosis who underwent stapedotomy were enrolled in this study. Patients were divided into two groups based on the technique used in stapedotomy: CO2 laser and perforator. Postoperative hearing gain and VNG findings were the main outcome measures. Subsequently, the two study groups were compared for analysis. The preoperative air-bone gap was 32.7±8.9 decibel (dB) in the study population and it was improved to 12.9±8.4 dB after operation. There were no differences in VNG findings and vertigo symptoms between the laser and perforator groups at postoperative day 2. There was no significant gain difference regarding the air conduction, bone conduction, and air-bone gap between the two groups (p=0.294, p=0.57, and p=0.37, respectively). Both CO2 laser and perforator stapedotomy have successful audiological outcomes with no difference in postoperative vestibular disturbance.

Full Text Available Introduction: The agricultural airplane pilot are daily exposed to intense noises, being susceptible to the noise-induced hearing loss (NIHL and its auditory and extra auditory effects. Objective: To analyze the audiological profile of this population, verifying the work's influence on its hearing. Method: It was realized a retrospective, individual, observational, and cross-sectional study through the data obtained by means of a questionnaire and audiometric thresholds of 41 agricultural pilots. To the statistical analysis were utilized the chi-square, Spearman, and Wilcoxon tests with significance level of 5%. Results: It was verified that 95,1% of the pilots use PPE ( personal protective equipment during flight and 58,5% have contact with pesticides. More than half of individuals referred to feel auditory and extra auditory symptoms, being the buzz the more frequent (29,1%. It has the occurrence of 29,3% of NIHL suggestive hearing loss and 68,3% of normality, taking this presence of unilateral notch in 24,4% and bilateral notch in 31,7%. It was found correlation statistically significant in the associations between time of service and the average of the acute frequencies in the right ear (p=0038, and in the left ear (p=0,010. It has a statistical tendency in the association between audiometric configuration and contact with pesticides (p=0,088. Conclusion: The hearing loss prevalence in this study was showed high. More than half of the sample has normal audiometric thresholds with notch configuration. Such data lead to the conclusion that the agricultural pilots, even with PPE use, they still suffer with the damages caused by noise, needing best proposals of hearing loss prevention.

Using therapeutic sound with progressive audiologic tinnitus management.

Science.gov (United States)

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).

Full Text Available Introduction: The noise induced hearing loss (NIHL has been studied for many years and today the specialized literature also studies the synergic action of chemicals. Objective: To research the audiologic findings and DPOAE in workers exposed to occupational noise and plaguecides and to compare them with data obtained in individuals without exposure to these harmful elements. Method: 51 individuals were evaluated (102 ears, divided into three groups. Group I was composed by 17 workers with exposure to noise and plaguecides, all with neurosensorial auditory loss; group II was composed by 17 workers with exposure to noise and plaguecides with audiometric thresholds within normality standards (up to 25 dBNA and group III by 17 healthy individuals without auditory alterations and without exposure to noise and plaguecides, control group. Results: In the audiologic anamnesis, as for groups I and II, we observed that the main auditory complaints presented by the workers were those of recruitment (29.5%, tinnitus (26.5%, allergy (23.5% and arterial hypertension (12%. The findings of the audiometry appointed that the research's individuals did not present with auditory losses in the frequencies of 500 Hz, 1 and 2 kHz, the losses occurred in the frequencies of 3 and 8 kHz. As for the distortion-product otoacoustic emissions (DPOAEs, we observed that the individuals in group III had a major incidence of responses when compared to those of groups I and II. Conclusion: The results analysis allowed us to conclude that the DPOAE test represents an important tool for follow up and prevention of NIHL.

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

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.

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.

Mondini dysplasia is a congenital malformation of the inner ear. To date, five individuals with this malformation have received cochlear implants at the South of England Cochlear Implant Centre. The aim of this study was to review the audiological findings of these individuals after implantation. The soundfield thresholds after implantation are in the region of 30-40 dB (A). The results of suprathreshold speech recognition tasks show substantial variability in performance but this is no greater than that obtained from implant users with no malformation. All individuals were able to detect and recognize a variety of environmental sounds that would previously have been inaudible. These findings, along with the reported improvement in quality of life, mean that Mondini dysplasia is not a contra-indication for multichannel cochlear implantation. This information will be useful to other centres when considering implantation in similar patients.

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

Hall, James W

2016-09-01

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.

The International Classification of Functioning Disability and Health (ICF) Core Sets for Hearing Loss (HL) were developed to serve as a standard for the assessment and reporting of the functioning and health of patients with HL. The aim of the present study was to compare the content of the intake documentation currently used in secondary and tertiary hearing care settings in the Netherlands with the content of the ICF Core Sets for HL. Research questions were (1) to what extent are the ICF Core Sets for HL represented in the Dutch Otology and Audiology intake documentation? (2) are there any extra ICF categories expressed in the intake documentation that are currently not part of the ICF Core Sets for HL, or constructs expressed that are not part of the ICF? Multicenter patient record study including 176 adult patients from two secondary, and two tertiary hearing care settings. The intake documentation was selected from anonymized patient records. The content was linked to the appropriate ICF category from the whole ICF classification using established linking rules. The extent to which the ICF Core Sets for HL were represented in the intake documentation was determined by assessing the overlap between the ICF categories in the Core Sets and the list of unique ICF categories extracted from the intake documentation. Any extra constructs that were expressed in the intake documentation but are not part of the Core Sets were described as well, differentiating between ICF categories that are not part of the Core Sets and constructs that are not part of the ICF classification. In total, otology and audiology intake documentation represented 24 of the 27 Brief ICF Core Set categories (i.e., 89%), and 60 of the 117 Comprehensive ICF Core Set categories (i.e., 51%). Various ICF Core Sets categories were not represented, including higher mental functions (Body Functions), civic life aspects (Activities and Participation), and support and attitudes of family (Environmental

Purpose: To find the audiological outcome after LINAC-based fractionated stereotactic irradiation (STI). Materials and methods: Twenty-four patients with vestibular schwannoma treated by fractionated STI between 1991 and 1997 had measurable hearing before STI and were followed audiologically for more than 6 months. The pure tone average (PTA) was measured by averaging the air-conduction threshold for five main frequencies (250-4000 Hz) before and periodically after STI in the 24 patients. Several possible prognostic factors for hearing preservation (defined as a PTA change at the last follow-up of less than 10 dB) were investigated. The median follow-up time was 22 months, ranging from 5 to 69 months. The irradiation schedule was 36 Gy in 20 fractions in 5 weeks to 44 Gy in 22 fractions in 6 weeks followed by 4 Gy/1 fraction boost. Results: The pure tone average before STI was distributed from 7 to 73 dB. Fifty percent of patients showed a change in PTA of less than 10 dB, 79.2% of patients showed a change in PTA of less than 20 dB and 20.8% of patients showed a change in PTA of more than 21 dB at the last follow-up. Only one patient (4%) became deaf. Cases with a sudden loss of hearing were more likely to experience hearing preservation than those with gradual loss of hearing (P<0.05). The mean age was younger in patients whose hearing was preserved (P<0.05). Poor pretreatment PTA appeared to linearly correspond to the changes in PTA (regression coefficient 0.78). The size of the tumor was not related to the change in PTA. No relationship was observed between the maximum or peripheral dose and the PTA change. The real benefit of stereotactic boost after small-field fractionated irradiation was not certain. Conclusion: Fractionated STI produced a hearing preservation rate compatible with meticulously collimated multi-spots single fraction irradiation. Further follow-up is required to confirm the long-term benefits of fractionation. (Copyright (c) 1998 Elsevier

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 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.

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.

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.

In conductive, mixed hearing losses and single-sided-deafness bone-anchored hearing aids are a well-established treatment. The transcutaneous transmission across the intact skin avoids the percutaneous abutment of a bone-anchored device with the usual risk of infections and requires less care.In this study, the audiological results of the Bonebridge transcutaneous bone conduction implant (MED-EL) are compared to the generally used percutaneous device BP100 (Cochlear Ltd., Sydney, Australia). Ten patients implanted with the transcutaneous hearing implant were compared to 10 matched patients implanted with a percutaneous device. Tests included pure-tone AC and BC thresholds and unaided and aided sound field thresholds. Speech intelligibility was determined in quiet using the Freiburg monosyllable test and in noise with the Oldenburg sentence test (OLSA) in sound field with speech from the front (S0). The subjective benefit was assessed with the Abbreviated Profile of Hearing Aid Benefit. In comparison with the unaided condition there was a significant improvement in aided thresholds, word recognition scores (WRS), and speech reception thresholds (SRT) in noise, measured in sound field, for both devices. The comparison of the two devices revealed a minor but not significant difference in functional gain (Bonebridge: PTA = 27.5 dB [mean]; BAHA: PTA = 26.3 dB [mean]). No significant difference between the two devices was found when comparing the improvement in WRSs and SRTs (Bonebridge: improvement WRS = 80% [median], improvement SRT = 6.5 dB SNR [median]; BAHA: improvement WRS = 77.5% [median], BAHA: improvement SRT = 6.9 dB SNR [median]). Our data show that the transcutaneous bone conduction hearing implant is an audiologically equivalent alternative to percutaneous bone-anchored devices in conductive hearing loss with a minor sensorineural hearing loss component.

In a clinical setting, theories of health behaviour change could help audiologists and other hearing health care professionals understand the barriers that prevent people with hearing problems to seek audiological help. The transtheoretical (stages of change) model of health behaviour change is one of these theories. It describes a person's journey towards health behaviour change (e.g. seeking help or taking up rehabilitation) in separate stages: precontemplation, contemplation, preparation, action, and, finally, maintenance. A short self-assessment measure of stages of change may guide the clinician and facilitate first appointments. This article describes correlations between three stages of change measures of different lengths, one 24-item and two one-item. Participants were recruited through an online hearing screening study. Adults who failed the speech-in-noise recognition screening test and who had never undergone a hearing aid fitting were invited to complete further questionnaires online, including the three stages of change measures. In total, 224 adults completed the three measures. A majority of the participants were categorised as being in one of the information- and help-seeking stage of change (contemplation or preparation). The three stages of change measures were significantly correlated. Conclusions Our results support further investigating the use of a one-item measure to determine stages of change in people with hearing impairment.

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.

It is often, but not always, accompanied by sensorineural hearing loss, the clinical severity and age of onset of which may be different from the other clinical features. Mutations in either ATP6V1B1 or ATP6V0A4 are the chief causes of primary distal renal tubular acidosis with or without hearing loss, although the loss is often milder in the latter. We describe a kindred with compound heterozygous alterations in ATP6V0A4, where hearing loss was formally diagnosed late in both siblings such that they missed early opportunities for hearing support. This kindred highlights the importance of routine audiologic assessments of all children with distal renal tubular acidosis, irrespective either of age at diagnosis or of which gene is mutated. In addition, when diagnostic genetic testing is undertaken, both genes should be screened irrespective of current hearing status. A strategy for this is outlined.Keywords: sensorineural hearing loss, renal tubular acidosis, recessive, genetics, mutation

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.

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. 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

To evaluate the functionality of the auditory system in patients who underwent radiotherapy and chemotherapy treatment with cisplatin to treat head and neck tumors. Case series with planned data collection. From May 2007 to May 2008 by the Department of Otorhinolaryngology and the Department of Oncology/Radiotherapy at Faculdade de Medicina de Marília. Audiological evaluation (Pure Tone Audiometry (air and bone conduction), Speech Audiometry, Tympanometry, Acoustic Reflex testing and Distortion Product Otoacoustic Emissions) was performed in 17 patients diagnosed with head and neck neoplasia and treated with chemotherapy, using cisplatin, and radiotherapy. 12 left ears (70.5%) and 11 right ears (64.7%) presented bilateral decreased hearing soon after the treatment for the frequency 1 kHz (mild auditory damage) and for the frequency 8 kHz (more significant auditory damage). Patients with head and neck cancer submitted to the conventional radiotherapy treatment, combined with the chemotherapy with cisplatin, presented a high incidence of decreased hearing by the end of treatment. Strong evidence was observed linking auditory alteration to the amount of radiotherapy treatment

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

Full Text Available Scope of the study: Vestibular pathology is a complex one, requiring a minute clinical evaluation, as well as numerous paraclinical investigations. The present study analyzes the contribution of the modern methods of vestibular and auditive investigation to the diagnosis of dizziness. Materials and method: The results of the investigations performed on 84 patients with peripheric vestibular syndrome, on whom a complete audiological and vestibular assessment had been also made, have been retrospectively analyzed. Results: Anamnestic data and the results of evaluation permitted classification of peripheric vestibular pathology according to topo-lesional and etiological criteria. The most frequently diagnosed diseases were: benign paroxysmal positional vertigo, Ménière syndrome and vestibular neuronitis. Conclusions: Testing of the vestibulo-ocular and vestibulo-spinal reflexes through videonystagmoscopy and, respectively, computerized dynamic posturography, besides tonal vocal audiometry and precocious auditive potentials, is especially important for a positive diagnosis and etiological differentiation of vestibular syndromes.

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.

In the course of previous investigations carried out in the Republic of Sakha (Yakutiya), we have identified the main molecular-genetic factor responsible for the hereditary impairment of hearing among the indigenous population (mostly the Yakuts).The disease was shown to be attributable to the c.-23+1G>A mutation localized in the splice donor site (exon 1) of the GJB2 (Cx26) gene. The present study involved the comprehensive audiological analysis of the patients homozygous for the c.-23+1G>A mutation in the GJB2 gene based on the results of the study of a large sample of the patients residing in Yakutiya. All individuals with the GJB2 genotype c.-23+1G>A/c.-23-1G>A (n=108) at the mean age of 14.32±4.7 years (all ethnic Yakuts)were examined with the use oftonal threshold audiometry for air conduction testing at the frequencies of 0.25, 0.5, 1.0, 2.0, 4.0, and 8.0 kHz and bone conduction testing at the frequencies of 0.25, 0.5, 1.0, and 4.0 with a step of 5.0 dB.The results of the ASSR test were used whenever tonal threshold audiometry proved impracticable The data obtained in the study characterize the allelic form of the disease associated with the GJB2 genotype c.-23+1G>A/c.-23-1G>A as the congenital bilateral symmetric (90.1%), sensorineural (90.1%) form of hearing impairment of variable severity (from grade 1 to complete deafness) with the «flat» audiological profile (median slope not more than 5.0 dB in the extended frequency range (EFR) of 0.5, 1.0, 2.0, and 4.0, kHz). It is concluded that the results of the audiological analysis performed in the present study give evidence of relatively homogeneous but variable in terms of severity impairment of hearing in the patients homozygous for the c.-23+1G>A mutation in the GJB2 (Cx26) gene. It may serve as a positive prognostic sign to be used in the development and prescription of hearing aids.

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.

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

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

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

Full Text Available Hearing loss is an etiologically heterogeneous trait with differences in the age of onset, severity and site of lesion. It is caused by a combination of genetic and/or environmental factors. A longitudinal study to examine the efficacy of early intervention for improving child outcomes is ongoing in Australia. To determine the cause of hearing loss in these children we undertook molecular testing of perinatal "Guthrie" blood spots of children whose hearing loss was either detected via newborn hearing screening or detected later in infancy. We analyzed the GJB2 and SLC26A4 genes for the presence of mutations, screened for the mitochondrial DNA (mtDNA A1555G mutation, and screened for congenital CMV infection in DNA isolated from dried newborn blood spots. Results were obtained from 364 children. We established etiology for 60% of children. One or two known GJB2 mutations were present in 82 children. Twenty-four children had one or two known SLC26A4 mutations. GJB2 or SLC26A4 changes with unknown consequences on hearing were found in 32 children. The A1555G mutation was found in one child, and CMV infection was detected in 28 children. Auditory neuropathy spectrum disorder was confirmed in 26 children whose DNA evaluations were negative. A secondary objective was to investigate the relationship between etiology and audiological outcomes over the first 3 years of life. Regression analysis was used to investigate the relationship between hearing levels and etiology. Data analysis does not support the existence of differential effects of etiology on degree of hearing loss or on progressiveness of hearing loss.

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.

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.

Full Text Available Objective: To describe the audiological findings (type, audiometric configuration, degree of hearing loss and its association with gender and age in subjects aged over 60 years, treated at outpatient clinic of specialties of Manaus. Methods: A cross-sectional epidemiological descriptive study conducted with the universe of elderly who underwent audiometry from January to December 2010, with a total of 574 subjects. To classify the type, degree and configuration of hearing loss, we used the criteria adopted by Santos & Russo, Davis & Silverman and Silman & Silverman, respectively. Statistical analysis was performed using measures of central tendency, dispersion and frequency distributions. To check for statistically significant differences, we used the chi-square test, with a significance level of 5% (p ≤ 0.05. Results: The prevalence of 94.4% (n = 542 of hearing loss, sensorineural predominantly (85.5%, n = 491 and mild (60%, n = 188 in females and degree moderate or greater in males (50%, n = 130, downward sloping (54.2%, n = 311 in both sexes. The percentage of normality was low, with 261 (3.4% for men and 313 (7.3% for women. Conclusion: The prevalence of hearing loss increased with age, being equal to 100% in individuals 80 years or older, and men have the worst hearing thresholds. There is need for greater awareness about hearing loss in the elderly, needing additional population-based and multicentric studies in order to support public policies.

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

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 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.

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

's syndrome is a rare congenital anomaly, of which the etiology is yet unknown, and characterized by a classical triad of ocular, auricular and vertebral abnormalities. FORMA DE ESTUDO: Serie report. MATERIAL AND METHOD: This study used 30 individuals presenting Goldenhar's syndrome, that were regularly enrolled in the Craniofacial Anomaly Rehabilitation Hospital (HRAC, of both sexes, varying from 8 to 34 years old. AIM: The goal was to characterize the audiologic profile to the individuals presenting this syndrome, thus, assuring a better treatment and orientation for them, and also the establishment of the frequency of contra-lateral auditory commitment in individual with the classical unilateral involvement. RESULTS: The auditory assessment of this study showed ATL, tympanometry, EOA-T and BERA. According to the results, we concluded that 35% (N=10 of the individuals presented, as a characteristic of the audiologic profile, loss of hearing type sensorioneural, mixed with varied levels from moderate to deep (7 uni and 3 bilateral; 13% (n=4 presented conductive loss (bilaterally with levels mild to severe and 3% (n=1 presented a unilateral deep type of sensorioneural loss. This study showed 40% n=12 with normal bilateral hearing and in 10% (n=3 it wasn't possible to establish the characteristic of the audiologic profile, since only the BERA was used as an assessment tool for establishing the electro-physiologic threshold. Of the twelve (12 individuals presenting unilateral malformations of the left ear, only two (02 presented contra-lateral auditory commitment of the ear, one type mixed with a severe level and one conductive of a moderate level. Considering the sex variable, the mayor predominance of the Goldenhar's syndrome was for females (57% compared to the males (43%, but these results weren't statistically significant, as well as for the unaffected anatomical side, that was predominantly the right side.

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.

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

Emmerich, Edeltraut; Rudel, Lars; Richter, Frank

2008-07-01

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.

2014-02-01

This discussion paper aims to synthesise the literature on patient-centred care from a range of health professions and to relate this to the field of rehabilitative audiology. Through review of the literature, this paper addresses five questions: What is patient-centred care? How is patient-centred care measured? What are the outcomes of patient-centred care? What are the factors contributing to patient-centred care? What are the implications for audiological rehabilitation? Literature review and synthesis. Publications were identified by structured searches in PubMed, Cinahl, Web of Knowledge, and PsychInfo, and by inspecting the reference lists of relevant articles. Few publications from within the audiology profession address this topic and consequently a review and synthesis of literature from other areas of health were used to answer the proposed questions. This paper concludes that patient-centred care is in line with the aims and scope of practice for audiological rehabilitation. However, there is emerging evidence that we still need to inform the conceptualisation of patient-centred audiological rehabilitation. A definition of patient-centred audiological rehabilitation is needed to facilitate studies into the nature and outcomes of it in audiological rehabilitation practice.

Otoacoustic (EOA-T and cochlear palpebral reflex. For newborns, those who failed the hearing screening in one or both ears, were referred to a second evaluation. In the retest, while the EOA-T test result in not passing on one or both ears, the child was referred for evaluation and otorhinolaringology management. After completing the Auditory Evoked Potential test, the team of evaluators decided whether it should refer the child to investigate the mutation. When there was suspicion of hearing impairment we collected 3 mL of peripheral venous blood for the detection of mutation in the connexin 26 gene. RESULTS: we observed the presence of conductive hearing loss in 2 neonates (0.22% and sensorineural in 1 (0.11%. In children with sensorineural hearing loss we detected the presence of 35delG mutation. CONCLUSION: the audiological assessment in conjunction with molecular tests of the main GJB2 gene mutations in newborns with suspected hearing loss contributed to the rapid audiological diagnostic, seeking early intervention, educational and genetic counseling and prognosis of the child.

A case series of patient were referred for evaluation and management to the Hearing Research Center.To describe the clinical picture of the patients with the key clinical feature of hearing loss for pure tones and reduction in speech discrimination out of proportion to the pure tone loss, having some of the criteria of auditory neuropathy (i.e. normal otoacoustic emissions, OAE, and abnormal auditory brainstem evoked potentials, ABR and lacking others (e.g. present auditory reflexes. Methods: Hearing abilities were measured by Pure Tone Audiometry (PTA and Speech Discrimination Scores (SDS, measured in all patients using a standardized list of 25 monosyllabic Farsi words at MCL in quiet. Auditory pathway integrity was measured by using Auditory Brainstem Response (ABR and Otoacoustic Emission (OAE and anatomical lesions Computed Tomography Scan (CT and Magnetic Resonance Image (MRI of brain and retrocochlea. Patient included in the series were 35 patients who have SDS disproportionably low with regard to PTA, absent ABR waves and normal OAE. Results: All patients reported the beginning of their problem around adolescence. Neither of them had anatomical lesion in imaging studies and neither of them had any finding suggestive of conductive hearing lesion. Although in most of the cases the hearing loss had been more apparent in the lower frequencies (i.e. 1000 Hz and less, a stronger correlation was found between SDS and hearing threshold at higher frequencies. These patients may not benefit from hearing aids, as the outer hair cells are functional and amplification doesn’t seem to help; though, it was tried for all. Conclusion: These patients share a pattern of sensory –neural loss with no detectable lesion. The age of onset and the gradual

Gan, Richard Wei Chern; Overton, Parisa; Benton, Claire; Daniel, Matija

2017-08-01

ENT surgeons may refer children with otitis media with effusion (OME) to audiology for consideration of hearing aids. They are an option for the treatment of OME, but are only effective if the child actually wears them. Our study investigated what proportion of children referred for hearing aids actually receive them, and whether children use them. Retrospective study of children referred to audiology from November 2013 to August 2014, including 70 children referred by ENT for hearing aids for OME, plus a further 5 children with OME given hearing aids through direct access audiology service. During the study period, there were 202 referrals of children to audiology, of which 70 (34.7%) were for consideration of hearing aids for OME. Of these 70 referred children, 37 (52.9%) were not fitted with hearing aids due to normal audiometry (23), asymptomatic mild hearing loss (7), nonattendance (3), clinical decision to just monitor hearing (1), parental decline (2), and unrecorded reason (1). A total of 38 children (including direct access patients) were fitted with hearing aids for OME. Majority (36/38) of children issued aids used them, 16 all day, 7 only at school, 1 only at home, 3 only when needed, and 9 used them for an unspecified duration; 1 child's use of hearing aids was unrecorded, and 1 child refused to use it. 21 were fitted bilaterally and 17 unilaterally. 37 were behind the ear aids and 1 a BAHA softband. A third of referrals to paediatric audiology by ENT are for consideration of hearing aids for OME. Only about half of children referred to audiology for hearing aids for OME actually receive them, as by the time they see audiology the hearing loss has frequently resolved or is asymptomatic so that aiding is unwarranted. Once fitted, they appear to be well accepted. Hearing aids have fair utilization in children fitted with them for OME. Copyright © 2017 Elsevier B.V. All rights reserved.

Full Text Available A audiometria de altas frequências (AAF é um exame audiológico importante na detecção precoce de perdas auditivas por lesões na base do ducto coclear. Nos últimos anos, a sua utilização foi facilitada pelo fato de os audiômetros comercializados passarem a incorporar frequências superiores a 8 kHz. Porém, existem diferenças relacionadas aos equipamentos utilizados, às metodologias empregadas e/ou aos resultados e interpretação. Assim, o objetivo deste artigo foi analisar a produção científica nacional sobre a aplicação clínica com AAF, para compreender sua utilização atual. Foram pesquisados textos publicados e indexados nas bases de dados LILACS, SciELO e Medline, num período de tempo de dez anos, utilizando como descritor "audiometria de altas frequências/high-frequency audiometry". Encontraram-se 24 artigos científicos nacionais utilizando AAF, cuja população avaliada, em sua maioria, apresentava de 18 a 50 anos de idade; 13 dos estudos determinaram os limiares utilizando como referência decibel nível de audição (dBNA; alguns estudos realizaram a comparação dos limiares auditivos tonais entre grupos para definir a normalidade; os autores relataram diferenças significativas nos limiares auditivos de altas frequências entre as idades. A AAF é utilizada na clínica audiológica para identificação precoce de alterações auditivas e no acompanhamento da audição de sujeitos expostos a drogas ototóxicas e/ou agentes otoagressores.High-frequency audiometry (HFA is an important audiological test for early detection of hearing losses caused by leasions in the base of the cochlear duct.

Full Text Available Initial audiological test was performed in 136 premature children with various gestational age born from single fetation. The children were divided into 2 groups: prematures with intrauterine growth restriction (IUGR and prematures with normal weight for their gestational age (normotrophy. The study showed that the rate of passing the initial audiological test using the method of DPOAE was lower in both ears in children with IUGR, than in children with normotrophy. The correlation between the results of initial audiological test and birth weight was found: the lower was weight, the higher was risk of absence of acoustic response registration on initial examination.

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.

Sandra du Plessis

2018-05-01

Full Text Available 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

Adult-onset hearing loss affects more than 20% of citizens in the US and in the EU. This second most frequent disability (World Health Organization 2001) is mostly due to aging and noise exposure ('sensorineural'). Although usage of hearing aids effectively increases life quality (Joore et al. 2003......; Anteunis 2002), in many western countries, only 15% of those who could benefit from this technology use it, e.g. in the USA, Switzerland, and Finland (Bisgaard 2009).

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.

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.

Kim, Kyoo Sang

2010-12-01

In this article, current status of noise exposure in workplaces, trend of workers with noise-induced hearing loss (NIHL), and prevalence of NIHL in workers by industry and job category in Korea were reviewed. In addition, trends of research on the audiological effects such as hearing loss from noise and occupational hearing loss from non-noise in Korea were addressed through reports in industrial audiology. Though noise exposure level has improved, noise still shows the highest rate of cases exceeding exposure limit among workplace hazards. NIHL is the most common occupational disease except work-related disease such as musculoskeletal disorders and cerebrovascular diseases, and NIHL prevalence is thought to be much higher than reported in official publications. Noise affecting hearing comes from various sources such as workplaces, military settings, areas with exposure to high noise, and specific noise sources. There is also occupational hearing loss by non-noise including chemicals such as organic solvents and heavy metals, barotrauma, and trauma due to welding spark. Noise affects daily life through audiological effects such as hearing loss and tinnitus, non-audiological physical effects (e.g., cardiovascular), and psychosocial and behavioral effects. Development of systematic and comprehensive hearing conservation programs for lowering the noise level in workplaces and preventing the NIHL, and preparation of technological, administrative system for its settlement at workplace are urgently needed.

Full Text Available A cisplatina é um agente quimioterápico que apresenta dentre seus efeitos colaterais a ototoxicidade. Este estudo teve como objetivos avaliar a audição de pacientes portadores de osteossarcoma expostos à cisplatina e verificar qual o método de investigação mais adequado para identificar precocemente as alterações auditivas induzidas por drogas ototóxicas. FORMA DE ESTUDO: Clínico prospectivo. MATERIAL E MÉTODO: 13 indivíduos portadores de osteossarcoma que receberam quatro ciclos de cisplatina de 120 mg/m²/ciclo, fracionados em dois dias de aplicação (60 mg/m²/dia, foram submetidos à avaliação audiológica - audiometria tonal liminar (250 a 18000 Hz e emissões otoacústicas transitórias (EOAT e por produto de distorção (EOAPD - antes do início do tratamento e após cada ciclo de cisplatina. RESULTADOS: Observou-se, nos valores médios, perda auditiva após a dose cumulativa de 480 mg/m² a partir de 8 kHz. Quanto aos valores individuais, 15,3% dos pacientes apresentaram perda auditiva de grau leve a moderado a partir de 3 kHz, 15,3% a partir de 4 kHz, 15,3% a partir de 6 kHz e 15,3% a partir de 8 kHz. Não foi observada redução na amplitude das EOAT precocemente à alteração dos limiares nas altas freqüências. Houve redução da amplitude das EOAPD concomitante ao aumento do limiar de audibilidade. CONCLUSÃO: A audiometria de altas freqüências é mais efetiva na detecção precoce da perda auditiva induzida por cisplatina. As EOAT e EOAPD podem ser usadas como complemento à avaliação audiométrica. Todos os pacientes expostos à cisplatina têm perda auditiva nas altas freqüências, e destes, 30,6% tem perda auditiva a partir das freqüências de 3 e 4 kHz consideradas importantes para a compreensão da fala.Cisplatin is an antineoplasic drug, which has ototoxicity as a side effect.

Full Text Available Background. Cleft palate is associated with recurrent otitis media with effusion and hearing loss. This study analysed the way these patients’ hearing is managed in Alder Hey Children’s Hospital. Method. A retrospective audit was carried out on cleft palate patients in Alder Hey Children’s Hospital. Audiology assessment and treatment options were reviewed. Comparisons were made between the use of ventilation tubes (VTs and hearing aids (HAs. The types of cleft, types of hearing loss, and the management output of the audiology regions were also reviewed. Results. The audiology assessments of 254 patients were examined. The incidence of VT insertion in this group of patients was 18.9%. The hearing aid incidence rate was 10.1%. The VT-related complication rate was 25.5% and the HA related complication rate was 9.1%. Conclusion. The data demonstrates that both treatments are viable, and a new protocol which combines the short term benefit of VT insertion with the lower complication rate of HA is required.

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.

Full Text Available OBJECTIVE: To investigate whether there is any relationship between otological as well as vestibular symptoms, audiological findings and type of temporomandibular disorder (articular, muscular and mixed; and to check the distribution of the temporomandibular disorders (TMD dysfunction degree in the research population. METHODS: A retrospective study involving 30 patients of both sexes, aged between 18 and 49 years old, diagnosed with TMD and dentofacial deformities, who were subject to clinical evaluation (muscle palpation, auscultation of temporomandibular joint during mandibular motion and measurement of jaw movement, audiological testing (pure tone audiometry and immittance testing and two questionnaires, one on otological and vestibular symptoms and the other on TMD anamnesis. Based on both the anamnesis questionnaire and the clinical assessment, the subjects were divided according to the type and degree of TMD dysfunction (mild, moderate and severe, and compared regarding the occurrence of auditory signs and symptoms, vestibular symptoms and audiological findings according to TMD type. RESULTS: The anamnesis questionnaire demonstrated higher prevalence (83.33% of severe TMD. Subjects with mixed TMD had more complaints about hypoacusis than those with muscular TMD (p < 0.05. The results showed no change in either audiological and immittance testing for all assessed individuals. CONCLUSION: Otological symptoms are present in subjects with TMD and dentofacial deformities, regardless of the classification of TMD (articular, muscular or mixed. Those with mixed TMD may have higher incidence of complaints about hypoacusis than subjects with muscular TMD. Further studies are needed to investigate the relationship between otological symptoms and the different types of TMD.

2016-01-01

Rates of hearing impairment in individuals with Autism Spectrum Disorders (ASD) are higher than those reported in the general population. Although ASD is not caused by hearing impairment, it may exacerbate symptomatology. Participants with ASD (N = 60) and typically developing peers (N = 16) aged 5-18 years underwent a comprehensive audiological screening (pure tone audiometry, uncomfortable loudness level, tympanometry, acoustic reflexes, distortion product otoacoustic emissions, and auditory brainstem response) and assessment of communication abilities (expressive/receptive language, articulation, phonological awareness, and vocal affect recognition). Incidence of abnormal findings on at least one measure of audiological functioning was higher for the ASD group (55%) than controls (14.9%) or the general population estimate (6%). The presence of sound sensitivity was also considerably higher for the ASD group (37%) compared with controls (0%) or general population estimates (8-15%). When participants with ASD were dichotomized into groups with and without evidence of clinical audiological abnormality, no significant differences were identified on measures of communication; however, results of correlational analyses indicated that variability in hearing thresholds at middle range frequencies (2000 Hz) was significantly related to performance on all measures of speech articulation and language after correction for multiple comparisons (r = -0.48 to r = -0.53, P <  0.0045). These findings suggest that dichotomized classification of clinical audiology may not be sufficient to understand the role of subclinical hearing loss in ASD symptomatology and that treatment studies for mild/subclinical hearing loss in this population may be worthwhile. © 2015 International Society for Autism Research, Wiley Periodicals, Inc.

Full Text Available INTRODUCTION: Age Related Hearing Loss (ARHL is defined as loss of hearing in elderly persons not influe nced by the extraneous factors like noise trauma etc or intrinsic like CVS related diseases or endocrinal disorders like Diabetes. Also termed as Presbycusis it is defined as the loss of hearing due to age related changes taking place in the auditory syste m starting from the pinna to the cortical centers in the brain. It does not include any other factor contributing or initiating the pathological changes in the auditory system resulting in hearing loss. All these changes in the tissues are not pathological but truly age related. The threshold of hearing is defined as the pure tone average across the frequencies of 0.5 to 8 kHz. The severity of hearing loss is graded as profound hearing loss : more than 90dB , severe to severe loss : 71 - 90 dB or more ; Moderate to severe hearing loss : 56 - 70 , Moderate hearing loss : 41 - 55 dB HL ; Mild hearing loss : 26 - 40 dB HL. Present study is to evaluate hearing loss in persons aged above 65 years both of those attending the Hospital for loss of hearing and those screened in a sur vey. AIM: To evaluate the hearing thresholds in individuals aged above 65 years attending the Government General Hospital and among the people attending the hearing screening done in the city of Warangal. The study also includes the review of the literature on ARHL. MATERIALS AND METHODS: 185 individuals aged above 65 years are evaluated for hearing thresholds with the help of pure tone audiometry and speech audiometry. Among the 185 individuals 102 are patients attending the Department of ENT for the compla ints of loss of hearing. The remaining 83 individuals are from the survey conducted to screen for hearing loss in the city of Warangal for the population aged above 65 years. Demographic data about the 185 individuals is collected. Pure tone audiogram and speech audiometry is done in all the patients. CONCLUSIONS: PTA and SRT values are similar in both the groups. Early old age groups presented with mild to severe types of deafness and loss in lower frequencies. Late old aged people showed profound hearing l oss and increased thresholds in higher frequencies. SRT estimation seemed more sensitive than calculating PTA in the persons above 85 years. Females showed 5 to 10 dB lower PTA values than males in all ages.

Wilson, Wayne J; O'Brien, Ian; Bradley, Andrew P

2013-01-01

Among orchestral musicians, horn players are one of the most at-risk groups for noise-induced hearing loss (NIHL). To investigate this group further, pure tone audiometry and a 14-item questionnaire were used to assess the hearing health, as well as attitudes and practices regarding hearing conservation, among 142 French horn players attending an international horn conference in Brisbane, Australia. Of this study's French horn players, 11.1% to 22.2%, and 17.7% to 32.9% of those aged ≤40 years, showed some form of hearing loss (corrected for age and gender) typical of NIHL, using conservative versus lenient criteria, respectively. Stepwise multiple regression analyses showed no obvious predictor of hearing loss in this study's participants. Of the 18% of participants who reported using hearing protection, 81% used this protection "sometimes" and 50% used generic, foam, or other inferior forms of protection. Continued efforts to better manage the hearing health of horn players is warranted particularly as any hearing loss will affect a horn player's ability to perform and therefore his or her livelihood. Managing the hearing health of horn players will be challenging, however, with no simple predictor of NIHL loss being identified in this study's sample.

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

Full Text Available Objective: To identify risk factors related to sensorineural hearing loss in elderly. Methods: The sample consisted of 60 selected elderly, divided into two groups: the Case Group, composed by 30 individuals, 21 females and 9 males, aged at least 60 years, presenting sensorineural hearing loss, and the Control Group, composed by 30 individuals matched on gender and age, with normal hearing. The patients were submitted to audiological anamnesis and tonal audiometry. The hearing impairment was defined according to average threshold greater than 35dBNA, in the frequencies of 1,000; 2,000 and 4,000 Hz, in the best ear. Results: Statistically significant odds ratios were: a to audiological history: noise exposure and family history of deafness; b to situations involving hearing difficulty: television, church, telephone, silent environment, spatial location of sound, difficulty with voices and noisy environment; c to otologic history: tinnitus, otorrhea and nausea; and d to medical history: visual problems, smoke, alcohol, thyroid problems and kidney disease. Conclusion: The findings of this study highlighted, for sensorineural hearing loss, risk factors related to audiologic, otologic and medical history, and to situations involving hearing difficulty.

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

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.

It was found that JIR children had potential sensory neural hearing loss and vestibular affection. Therefore, this study recommends: early complete audiologic evaluation of JIA child followed by regular follow-up, including TOAEs, extended high-frequency audiometry, and VNG. This follow-up is important for preliminary diagnosis and management in order to prevent the negative impact of hearing loss on a child's life. The aim of this study was to assess hearing in children with Juvenile idiopathic arthritis (JIA) and compare them with a healthy control group. In addition to conventional audiometry, extended high-frequency audiometry and Transient otoacoustic emission (TOAEs) were used. This study also tried to investigate the vestibular function in JIR children by videonystagmography (VNG). The study group comprised of 28 children with JIR and 28 healthy children. All subjects were examined audiologically using basic audiological evaluation, high-frequency audiometry, TOAEs, and VNG. Children with JIR had apparent normal peripheral hearing in conventional audiometry; sub-clinical sensory neural hearing loss was detected. This sub-clinical hearing loss appeared in statistically significant difference between them and normal in high-frequency audiometry and TOAEs. VNG test results showed affected tracking and second tests.

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.

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.

We analyzed audiologic and surgical findings in patients with conductive hearing loss (CHL) with an intact tympanic membrane (TM) that was of a non-inflammatory origin. We reviewed data from patients who underwent exploratory tympanotomy for CHL with intact TM from January 1995 to November 2012. Patients with diseases of non-inflammatory origin were enrolled (69 patients; 79 ears). Patients were categorized into two groups: non-trauma (50 ears) and trauma (29 ears). Demographic data, intraoperative findings, and audiologic results were obtained and analyzed. Overall, the second decade was the most common age of diagnosis in both the non-trauma and trauma groups. Operative findings showed that ossicular dislocation was more prevalent than ossicular fixation; all trauma group subjects had ossicular dislocation. Short columellization or partial ossicular replacement was the most frequently adopted surgical procedures in both groups. Overall, audiologically, air-conduction thresholds (ACs) and air-bone gaps were significantly improved over the short- and long-term period in both groups. However, the non-trauma group had significantly higher preoperative ACs than the trauma group, especially at low frequencies. This study provides clinicians with useful information regarding the clinical characteristics of CHL with intact TM of non-inflammatory origin. Copyright © 2015 Elsevier Ireland Ltd.

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.

The role of bone conduction hearing aids in congenital unilateral hearing loss: A systematic review.

Liu, C Carrie; Livingstone, Devon; Yunker, Warren K

2017-03-01

To systematically review the literature on the audiological and/or quality of life benefits of a bone conduction hearing aid (BCHA) in children with congenital unilateral conductive or sensorineural deafness. A systematic search was performed according to the PRISMA guidelines using the PubMed, Medline, and Embase databases. Data were collected on the following outcomes of interest: speech reception threshold, speech discrimination, sound localization, and quality of life measures. Given the heterogeneity of the data for quantitative analysis, the results are qualitatively summarized. Eight studies were included in the review. Four studies examined the audiological outcomes associated with bone conduction hearing aid implantation. There was a consistent gain in speech reception thresholds and speech discrimination, especially in noisy environments. Results pertaining to sound localization was inconsistent. The studies that examined quality of life measures reported a high usage rate of BCHAs among children. Quality of life improvements are reported with suggested benefit in the subdomain of learning. Given the potential benefits of a BCHA, along with the fact that it can be safely trialed using a headband, it is reasonable to trial a BCHA in children with congenital unilateral deafness. Should the trial offer audiological and/or quality of life benefits for the individual child, then BCHA implantation can be considered. Copyright © 2017 Elsevier B.V. All rights reserved.

Establishing a pharmacotherapy induced ototoxicity programme within a service-learning approach

2015-06-01

Full Text Available Pharmacotherapy-induced ototoxicity is growing, especially in developing countries such as South Africa. This highlights the importance of ototoxicity monitoring and management of hearing loss. This article focuses on the establishment of an ototoxicity clinic as a site for the implementation of a service-learning module in the Audiology programme. The clinic offers a unique opportunity of collaboration between pharmacists and an audiologist where pharmacotherapy-induced ototoxicity is uniquely monitored. The Sefako Makgatho Health Sciences University (SMU provides training to both the disciplines audiology and pharmacy. The main aim of this article is to describe how ototoxicity monitoring is implemented in the curriculum within such an academic service-learning approach. Through service learning students develop a deeper understanding of course content, acquire new knowledge and engage in civic activity. It simultaneously provides a unique opportunity for interdisciplinary collaboration between the disciplines of audiology and pharmacy. The objectives for this programme are therefore to facilitate learning and to provide a service to the local community by identifying, preventing and monitoring medicine-induced hearing loss in in-hospital and out-patients; as well as to establish inter-disciplinary collaboration between the disciplines and stakeholders for more effective service delivery. The constant interdisciplinary teamwork between the audiologist, pharmacist, physician and nursing staff in the wards results in best practice and management of patients with ototoxic damage.

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.

Functional and social results of osseointegrated hearing aids

Directory of Open Access Journals (Sweden)

Inmaculada MORENO-ALARCÓN

2017-06-01

Full Text Available Introduction and objective: Osseointegrated implants are nowadays a good therapeutic option for patients suffering from transmission or mixed hearing loss. The aims of this study are both to assess audiology benefits for patients with osseointegrated implants and quantify the change in their quality of life. Method: The study included 10 patients who were implanted in our hospital between March 2013 and September 2014. The instrument used to quantify their quality of life was the Glasgow Benefit Inventory (GBI and a questionnaire including three questions: use of implant, postoperative pain and whether they would recommend the operation to other patients. Audiology assessment was performed through tone audiometry and free field speech audiometric testing. Results: The average total benefit score with the Glasgow Benefit Inventory was +58, and the general, social and physical scores were +75, +18 and +29, respectively. The improvement with the implant regarding free-field tonal audiometry at the frequencies of 500, 1000 and 2000 Hz was found to be statistically significant, as was the difference between verbal audiometry before and after implantation. Discussion: Improvements in surgical technique for osseointegrated implants, at present minimally invasive, foregrounds the assessment of functional and social aspects as a measure of their effectiveness. Conclusions: The use of the osseointegrated implant is related to an important improvement in the audiological level, especially in patients with conductive or mixed hearing loss, together with a great change in the quality of life of implanted patients.

2017-01-01

Full Text Available Introduction: Noonan syndrome (NS is a heterogeneous genetic disease that affects many parts of the body. It was named after Dr. Jacqueline Anne Noonan, a paediatric cardiologist.Case Report: We report audiological tests and auditory brainstem response (ABR findings in a 5-year old Malay boy with NS. Despite showing the marked signs of NS, the child could only produce a few meaningful words. Audiological tests found him to have bilateral mild conductive hearing loss at low frequencies. In ABR testing, despite having good waveform morphology, the results were atypical. Absolute latency of wave V was normal but interpeak latencies of wave’s I-V, I-II, II-III were prolonged. Interestingly, interpeak latency of waves III-V was abnormally shorter.Conclusion:Abnormal ABR results are possibly due to abnormal anatomical condition of brainstem and might contribute to speech delay.

[Diagnosis and management of Mondini malformation].

1997-02-01

Owing to the development of imaging technology and audiology, some of the sensorineural hearing loss cases that were previcusly considered to be of unknown cause have been found to be inner ear malformation. Five cases of Mondini malformation are reviewed in this paper. CSF otorhinorrhea occurred in four cases, Klippel-Feil syndrome in three, and concurrent otosclerosis in one patient. In discussion, the authors point out that: 1) CT scanning is an supplement to audiologic tests for such patients; 2) perilymph fistula in Mondini malformation is often found at the oval window and its vicinity, the foot plate and the round window; 3) the fistula can be treated by plugging with fascial tissue via tympanoplastic approach with endaural incision. The mucosa around the fistula should be stripped away and the plugging tissue should be of dumb-bell shape.

Mobile phones have come into widespread use. There are a lot of possible adverse effect to health. Use of mobile phone generate potentially harmful radiofrequency electromagnetic field (EMF) particularly for the hearing aspect. 98 subjects underwent hearing evaluations at Department of Otolaryngology, Faculty of Medicine, King Chulalongkorn Memorial Hospital, Chulalongkorn University. 31 males and 67females, mean age was 30.48 +/- 9.51 years old, all subjects were investigated the hearing level by audiometry, tympanometry, otoacoustic emission (OAE) and auditory brain stem evoked response (ABR). The average of using time were 32.54 +/- 27.64 months, 57 subjects usually used the right side and 41 the left side. Average time of use per day was 26.31 +/- 30.91 minutes (range from 3 to 180 mins). When the authors compared the audiogram, both pure tone and speech audiometry, between the dominant and nondominant side, it indicated that there is no significant different. When the authors focused on the 8 subjects that used the mobile phone more than 60 mins per day. It indicated that the hearing threshold of the dominant ears was worse than the nondominant ears.

Full Text Available Introduction: The most relevant clinical symptom in Waardenburg syndrome is profound bilateral sensorioneural hearing loss. Aim: To characterize and describe hearing outcomes after cochlear implantation in patients with Waardenburg syndrome to improve preoperative expectations. Method: This was an observational and retrospective study of a series of cases. Children who were diagnosed with Waardenburg syndrome and who received a multichannel cochlear implant between March 1999 and July 2012 were included in the study. Intraoperative neural response telemetry, hearing evaluation, speech perception, and speech production data before and after surgery were assessed. Results: During this period, 806 patients received a cochlear implant and 10 of these (1.2% were diagnosed with Waardenburg syndrome. Eight of the children received a Nucleus 24® implant and 1 child and 1 adult received a DigiSonic SP implant. The mean age at implantation was 44 months among the children. The average duration of use of a cochlear implant at the time of the study was 43 months. Intraoperative neural responses were present in all cases. Patients who could use the speech processor effectively had a pure tone average of 31 dB in free-field conditions. In addition, the MUSS and MAIS questionnaires revealed improvements in speech perception and production. Four patients did not have a good outcome, which might have been associated with ineffective use of the speech processor. Conclusion: Despite the heterogeneity of the group, patients with Waardenburg syndrome who received cochlear implants were found to have hearing thresholds that allowed access to speech sounds. However, patients who received early intervention and rehabilitation showed better evolution of auditory perception.

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 (phigh frequencies. Compared with control group, distortion products and SNR of the BD patients were lower in all of the tested frequencies (phigh frequencies and decreased signal-noise ratios (SNR) in distortion product otoacoustic emission (DPOAE) indicate a cochlear involvement in patients with BD.

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.

2017-12-01

Full Text Available Objective: Sensorineural hearing loss can occur as a complication of autoimmune and inflammatory diseases. Although psoriasis is also a chronic inflammatory skin disease characterized by T-cell mediated hyper proliferation of the keratinocytes, the information about the relationship between audiological disorders is limited in the literature and the relationship with vestibular disorders has not been investigated before. In this study, we aimed to investigate the presence of audiovestibular disorders and their relationship with disease parameters. Methods: Sixty-one patients with psoriasis and 61 healthy individuals were included in this prospective cross-sectional study. Those with possible etiologic factors that may lead to hearing and balance disorders were not included in the study. All participants were first performed a full ear, nose and throat examination. Subsequently, full audiological examination (pure audiometry, autoacoustic emission, stapes reflex, detection threshold of speech and discrimination and electronystagmography tests were performed in the audiology laboratory where sound isolation was provided. Psoriasis severity was assessed by psoriasis area and severity index, body surface area and general evaluation of researcher. Results: There were significant differences between patients and controls in terms of audiovestibular symptoms. According to audiograms, predominant bilateral sensorineural hearing loss was detected in high frequency in psoriasis patients. The vestibular abnormalities in patients with psoriasis were found to be more frequent than those in controls, only saccadic test values were observed as statistically significant. Conclusion: Our study demonstrates that audiovestibular abnormalities are significantly associated with psoriasis. Therefore, patients with psoriasis should be evaluated for the co-occurrence of hearing loss or vestibular problems which might affect patients’ quality of life.

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.

Hennig, Tais Regina

2011-01-01

Full Text Available Introduction: Tinnitus and hyperacusis are increasingly frequent audiological symptoms that may occur in the absence of the hearing involvement, but it does not offer a lower impact or bothering to the affected individuals. The Medial Olivocochlear System helps in the speech recognition in noise and may be connected to the presence of tinnitus and hyperacusis. Objective: To evaluate the speech recognition of normal-hearing individual with and without complaints of tinnitus and hyperacusis, and to compare their results. Method: Descriptive, prospective and cross-study in which 19 normal-hearing individuals were evaluated with complaint of tinnitus and hyperacusis of the Study Group (SG, and 23 normal-hearing individuals without audiological complaints of the Control Group (CG. The individuals of both groups were submitted to the test List of Sentences in Portuguese, prepared by Costa (1998 to determine the Sentences Recognition Threshold in Silence (LRSS and the signal to noise ratio (S/N. The SG also answered the Tinnitus Handicap Inventory for tinnitus analysis, and to characterize hyperacusis the discomfort thresholds were set. Results: The CG and SG presented with average LRSS and S/N ratio of 7.34 dB NA and -6.77 dB, and of 7.20 dB NA and -4.89 dB, respectively. Conclusion: The normal-hearing individuals with or without audiological complaints of tinnitus and hyperacusis had a similar performance in the speech recognition in silence, which was not the case when evaluated in the presence of competitive noise, since the SG had a lower performance in this communication scenario, with a statistically significant difference.

Initial results from the newborn hearing screening programme in Ireland.

LENUS (Irish Health Repository)

O'Connor, A

2013-03-02

INTRODUCTION: Hearing screening programmes aim to detect hearing loss in the neonate. The Health Service Executive (HSE) South was the first phase of a national roll-out of a neonatal hearing screening programme in Ireland, going live on 28 April 2011. RESULTS: Over 11,738 babies have been screened for permanent childhood hearing impairment (PCHI) during the first 12 months. The percentage of eligible babies offered hearing screening was 99.2 %. Only 0.2 % (n = 25) of those offered screening declined. 493 (4 %) were referred for immediate diagnostic audiological assessment. The average time between screen and diagnostic audiology appointment was 2 weeks. 15 (1.3\\/1,000) babies have been identified with a PCHI over the 12-month period. 946 (4 %) babies screened were admitted to the neonatal intensive care unit (NICU) for >48 h. The prevalance of PCHI is 7.3\\/1,000 in the NICU population compared to 0.6\\/1000 in the well baby population. 214 (1.8 % of total babies screened) had a clear response in the screening programmes, but were deemed to be at risk of an acquired childhood hearing impairment. These babies will be reassessed with a diagnostic audiology appointment at 8-9 months of age. To date, there is one case of acquired hearing impairment through this targeted follow-up screen. Of the 15 cases of PCHI identified, 8 (53 %) of these had one or more risk factors for hearing loss and 7 (37 %) were admitted to the NICU for >48 h. Four babies were referred for assessment at the National Cochlear Implant Centre.

Conclusion: Cochlear-facial dehiscence can predispose patients to post-implant FNS. Prior temporal bone irradiation may carry a higher risk of FNS. We recommend scrutiny for CFD in CTs of CI candidates and appropriate risk counseling for FNS if CFD is discovered and more frequent monitoring for FNS by audiology.

In the present study, we evaluated peripheral and central auditory pathways in professional musicians (with and without hearing loss) compared to non-musicians. The goal was to verify if music exposure could affect auditory pathways as a whole. This is a prospective study that compared the results obtained between three groups (musicians with and without hearing loss and non-musicians). Thirty-two male individuals participated and they were assessed by: Immittance measurements, pure-tone air conduction thresholds at all frequencies from 0.25 to 20 kHz, Transient Evoked Otoacoustic Emissions, Auditory Brainstem Response (ABR), and Cognitive Potential. The musicians showed worse hearing thresholds in both conventional and high frequency audiometry when compared to the non-musicians; the mean amplitude of Transient Evoked Otoacoustic Emissions was smaller in the musicians group, but the mean latencies of Auditory Brainstem Response and Cognitive Potential were diminished in the musicians when compared to the non-musicians. Our findings suggest that the population of musicians is at risk for developing music-induced hearing loss. However, the electrophysiological evaluation showed that latency waves of ABR and P300 were diminished in musicians, which may suggest that the auditory training to which these musicians are exposed acts as a facilitator of the acoustic signal transmission to the cortex.

Pérez-Carbonell, Tomàs; Pla-Gil, Ignacio; Redondo-Martínez, Jaume; Morant-Ventura, Antonio; García-Callejo, Francisco Javier; Marco-Algarra, Jaime

We included 9 patients implanted with Baha ® Attract. All our patients were evaluated by free field tonal audiometry, free field verbal audiometry and free field verbal audiometry with background noise, all the tests were performed with and without the device. To evaluate the subjective component of the implantation, we used the Glasgow Benefit Inventory (GBI) and Abbreviated Profile of Hearing Aid Benefit (APHAB). The auditive assessment with the device showed average auditive thresholds of 35.8dB with improvements of 25.8dB over the previous situation. Speech reception thresholds were 37dB with Baha ® Attract, showing improvements of 23dB. Maximum discrimination thresholds showed an average gain of 60dB with the device. Baha ® Attract achieves auditive improvements in patients for whom it is correctly indicated, with a consequent positive subjective evaluation. This study shows the attenuation effect in transcutaneous transmission, that prevents the device achieving greater improvements.

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

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

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.

2017-09-20

Newborn hearing screening has to be considered the first step of a program for the identification, diagnosis, treatment and habilitation/rehabilitation of children with hearing impairment. In Tuscany Region of Italy, the universal newborn hearing screening is mandatory since november 2007. The first guidelines for the execution of the screening have been released in June 2008; then many other Italian regions partially or totally adopted these guidelines. On the basis of the experience from 2008 and according to the recent evidences in the scientific literature, a new screening protocol was released in Tuscany region. The new protocol is an evolution of the previous one. Some issues reported in the previous protocol and in the Joint Committee on Infant Hearing statement published in 2007 were revised, such as the risk factors for auditory neuropathy and for late onset, progressive or acquired hearing loss. The new updated guidelines were submitted to the Sanitary Regional Council and then they have been approved in August 2016. The updated screening protocol is mainly aimed to identify newborns with a congenital moderate-to-profound hearing loss, but it also provides indications for the audiological follow-up of children with risk's factor for progressive or late onset hearing loss; further it provides indications for the audiological surveillance of children at risk for acquired hearing impairment. Then, in the new guidelines the role of the family paediatrician in the newborn hearing screening and audiological follow-up and surveillance is underscored. Finally the new guidelines provide indications for the treatment with hearing aids and cochlear implant, in accordance with the recent Italian Health Technology Assessment (HTA) guidelines. In the paper we report the modality of execution of the universal newborn hearing screening in the Tuscany Region, according to the recently updated protocol. The main features of the protocol and the critical issues are

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.

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

Overview of a public health approach to pediatric hearing impairment in the Pacific Islands.

2016-07-01

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.

2018-02-01

Schwannoma of the hypoglossal nerve is rare. This case report documents an atypical abnormality of the cervical vestibular evoked myogenic potential (cVEMP) in a patient with schwannoma of the hypoglossal nerve. The observed abnormality was attributed to the proximity of the hypoglossal nerve to the spinal accessory nerve in the medullary cistern and base of the skull. To report cVEMP abnormality in a patient with hypoglossal nerve schwannoma and provide an anatomical correlation for this abnormality. Case report. A 44-yr-old woman. Pure-tone and speech audiometry, tympanometry, acoustic stapedial reflex, auditory brainstem response, and cVEMP testing were performed. The audiological test results were normal except for the absence of cVEMP on the lesion side (right). A cVEMP abnormality indicating a compromised spinal accessory nerve was observed in a patient with hypoglossal nerve schwannoma. This case report highlights the importance of recording cVEMP in relevant neurological conditions and provides clinical proof for the involvement of the spinal accessory nerve in the vestibulocollic reflex pathway.

A retrospective review was performed of 113 consecutive patients with unilateral or bilateral conductive or mixed hearing loss referred to the Greater Manchester bone-anchored hearing aid (BAHA) programme between September 2008 and August 2011. 98 (86.7 %) patients were deemed audiologically suitable for BAHA implantation. Of these, 38 (38.8 %) had BAHA implanted; 60 (61.2 %) patients declined. Of those who declined, 27 (45 %) cited anxiety over surgery, 18 (30 %) cited cosmetic reasons, 16 (26.7 %) perceived limited benefit from the device and six (10 %) preferred conventional hearing aids. Our study highlights a 38.8 % BAHA uptake rate in audiologically suitable patients. The main reasons cited for rejection of BAHA were anxiety over surgery and cosmetic concerns. It is important that clinicians address these early during consultation with prospective BAHA recipients and avoid rushing to implant these patients with a bone-anchored hearing aid.

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 (planguages makes possible its application in international multicenter studies.

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.

Experiences with bimodal hearing and bilateral cochlear implantation in the elderly

Full Text Available With the geriatric population being the fastest growing segment of our society the number of elderly people with different levels of hearing impairments is increasing. According to the German Society of Hearing Impaired there are concerned 37% of the 60-69-year-old and 54% of the over 70-year-old. Furthermore the needs of the elderly are changing with augmented social activity and agility compared to former times: 80 is the new 70. After initial concerns about poor audiologic performance and added peri- and postoperative risks because of comorbidities, cochlear implantation is becoming more and more the method of choice also for postlingually deaf people of higher age. With the demographic shift there can be observed a trend reversal: the proportion of implantees is sliding from the young to the senior and duration of deafness at the time of implantation is declining (Battmer 2010. It is therefore necessary to investigate the impact of cochlear implantation on audiologic performance and quality of life in this growing age group.

presented normal results in pure-tone and speech audiometry; however, speech discrimination scores were lower on the phenylketonuria group. Immitance tests revealed normal tympanograms for all children, but stapedial reflex thresholds demonstrated higher thresholds in 2 and 4 kHz for children with phenylketonuria. The suppresion of transient otoacoustic emissions did not show difference in the comparison between groups. CONCLUSION: The basic audiologic assessment do not identify hearing disorders in children with phenylketonuria; however, speech discrimination scores were lower and stapedial reflexes were higher in these children, which may indicate auditory processing disorders. The study of the suppression of transient otoacoustic emissions demonstrated integrity of the olivocochlear efferent system in children with phenylketonuria.

To describe disease progression and treatment outcomes over a 20-year period (ages 5-25) in a young man with Norrie disease (occuloacousticocerebral dysplasia), ND; OMIM #310600. Affected individuals are born blind and develop progressive sensory loss with onset in adolescence. This disease is X-linked and has been associated with mutations of the NDP gene (Xp11.4). The patient was followed using repeated audiograms, as well as reports of educational progress and hearing aid use. The specific mutation was found by molecular analysis. The patient demonstrated progressive sensory loss with good preservation of word recognition. The loss was initially high frequency and asymmetric in adolescence and became more severe, more symmetric and affected practically all frequencies by the end of childhood. Educational progress was affected by the cognitive effects of the syndrome, and hearing aid use was very effective. A bilateral progressive sensory loss with good preservation of word recognition was documented in detail. The residual word recognition supported good use of hearing aids in this case.

It is recommended to perform follow-up tympanometry and if necessary tonal audiometry in children who have normal plain otoscopy findings after recovering from acute otitis media (AOM). Children with Type B tympanogram, 3 months following the onset of AOM, are very likely to have a conductive hearing loss. Type B tympanogram is a much better indicator of effusion in the middle ear compared to plain otoscopy. This study was undertaken to investigate the frequency and duration of middle ear effusion in children following an episode of acute otitis media, to track changes in tonal audiometry and tympanometry findings in the post-AOM period, and recognize the optimal timing for performing both tests. In this study, 125 children aged 5-7 years with bilateral AOM were randomly selected and separately followed up for 3 months. The children underwent six ear, nose, and throat (ENT 1-6) examinations, six tympanometries (TM 1-6), and three tonal audiometries (TA 1-3). Evaluation of nasopharynx was done at the ENT 1 examination. Children who received ventilation tubes were followed for 21 month altogether. At the first otoscopy, pathological findings were recorded in 250 ears/125 children (100.0%). The number of pathological otoscopy findings decreased at each subsequent examination. At ENT 6 all children had normal otoscopy findings. Type B tympanogram was detected in 49/250 (19.6%) ears at TM 6, performed 3 months following the onset of the disease. At the TA 1 conductive hearing impairment was recorded in 158/250 (63.2%) ears, at TA 2 in 66/250 (26.4%), and at TA 3 in 39/250 (15.6%). Most of them were associated with Type B tympanogram.

Pereira, José Roberto

2009-09-01

Full Text Available Introduction: The industrial technological advance has brought benefits and a series of implications that may commit the worker's health and life quality. The exposure to physical, chemical agents and organizational stressors contribute for the increase of work accidents risks. The noise, taken as the most frequent physical agent in the work environment, may cause auditory alterations called Noise-Induced Hearing Loss that affect the communication and life quality of the workers. Objective: To research the auditory health of employees in a funeral urns factory. Method: 90 workers took part in this study, aged between 16 and 52 years, exposed to sound pressure levels equal or higher than 85 dBNPS, vibration and/or chemical agents in the work environment. We carried out a specific interview and Threshold Tonal Audiometry. Results: This study identified altered audiometry results in 13.33% the right ear and 16.67% in the left ear and the age also influenced these auditory thresholds. Conclusion: The accomplishment of a workers' health surveillance program with all people involved is critical and will contribute for the human resources formation, in the management to proceed with actions as well as those by the proper workers being careful of their health.

Relating working memory to compression parameters in clinically fit hearing AIDS.

Souza, Pamela E; Sirow, Lynn

2014-12-01

Several laboratory studies have demonstrated that working memory may influence response to compression speed in controlled (i.e., laboratory) comparisons of compression. In this study, the authors explored whether the same relationship would occur under less controlled conditions, as might occur in a typical audiology clinic. Participants included 27 older adults who sought hearing care in a private practice audiology clinic. Working memory was measured for each participant using a reading span test. The authors examined the relationship between working memory and aided speech recognition in noise, using clinically fit hearing aids with a range of compression speeds. Working memory, amount of hearing loss, and age each contributed to speech recognition, but the contribution depended on the speed of the compression processor. For fast-acting compression, the best performance was obtained by patients with high working memory. For slow-acting compression, speech recognition was affected by age and amount of hearing loss but was not affected by working memory. Despite the expectation of greater variability from differences in compression implementation, number of compression channels, or attendant signal processing, the relationship between working memory and compression speed showed a similar pattern as results from more controlled, laboratory-based studies.

Introduction Standard criteria exist for diagnosing different types of hearing loss, yet audiologists interpret audiograms manually. This pilot study examined the feasibility of standardised interpretations of audiometry in a telehealth model of care. The aim of this study was to examine diagnostic accuracy of automated audiometry in adults with hearing loss in an asynchronous telehealth model using pre-defined diagnostic protocols. Materials and methods We recruited 42 study participants from a public audiology and otolaryngology clinic in Perth, Western Australia. Manual audiometry was performed by an audiologist either before or after automated audiometry. Diagnostic protocols were applied asynchronously for normal hearing, disabling hearing loss, conductive hearing loss and unilateral hearing loss. Sensitivity and specificity analyses were conducted using a two-by-two matrix and Cohen's kappa was used to measure agreement. Results The overall sensitivity for the diagnostic criteria was 0.88 (range: 0.86-1) and overall specificity was 0.93 (range: 0.86-0.97). Overall kappa ( k) agreement was 'substantial' k = 0.80 (95% confidence interval (CI) 0.70-0.89) and significant at p loss. This method has the potential to improve synchronous and asynchronous tele-audiology service delivery.

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.

Up to 40% of children with hearing loss present with other developmental disabilities. The purpose of this study was to document the prevalence of autism spectrum disorders (ASD) in children with permanent hearing loss, to describe the audiologic characteristics, and to examine clinical management. Prospective data related to clinical characteristics of children identified with hearing loss and ASD were examined. A retrospective chart review was also conducted to explore clinical management and uptake of amplification. The study included all children in one Canadian region identified with permanent hearing loss and followed from 2002-2010. Of a total of 785 children with permanent hearing loss, 2.2% (n = 17) also received a diagnosis of ASD. The 13 boys and 4 girls presented with a range of audiologic profiles from unilateral to profound bilateral hearing loss. Four of five children with unilateral hearing loss experienced progression to bilateral loss. Amplification was recommended for all but one child and 9 of 16 children continued to use their hearing devices. The higher prevalence rate of ASD in this clinical population is consistent with previous reports. Our findings suggest that some children with autism can derive benefits from the use of amplification.

Otoacoustic emissions (OAE) technology, used widely in newborn hearing screening programs and validated by professional organizations as a reliable and objective tool, is beginning to be recognized as superior to subjective methods when screening young children in a variety of settings. This study examines the efficacy of integrating OAE hearing screening into services routinely provided in health care settings. Three federally funded clinics serving low-income and uninsured people in a metropolitan area participated in the 10-month study. Subjects included 846 children (842 in the target population children did not pass the initial screening. Audiological evaluation was sought for children not passing a subsequent OAE screening. Of the 846 children screened, 814 (96%) ultimately passed the screening or audiological assessment and 29 (3%) exited the study. Three children (1 was 5) were identified with permanent hearing loss. The rate of identification of permanent hearing loss in this study is similar to findings from a study of OAE screening in early childhood educational settings. OAE screening holds the potential for being an effective method for helping to identify young children with permanent hearing loss in primary care settings.

Since 1997 a newborn hearing screening programme has been implemented by the U.O. Neurologia-Neurofisiopatologia and Dipartimento di Neonatologia of the Istituti Clinici di Perfezionamento ICP in Milan for both babies with no risk and those at risk of hearing impairment. This programme was named the Milan Project. The protocol for no-risk babies consisted of three stages: in the first two stages, newborns were tested with transient click-evoked otoacoustic emissions (TEOAE), in the third one with conventional auditory brainstem responses (ABR). The first TEOAE test was performed by 36 h of age, before discharge, the second one after 15-30 d in case of referral, and the third one, by ABR, for those babies who failed the second TEOAE stage. Newborns at audiological risk were submitted to conventional ABR before the third month of corrected age. Some of this latter population was also submitted to the TEOAE test. The entire tested population (no-risk babies and newborns at audiological risk) consisted of 19 777 babies: 19 290 without risk ("no risk") and 487 at risk ("at risk"). During the course of the Milan Project, hearing impairment (ABR threshold equal to or greater than 40 dB nHL) was identified in 63 newborns (19 from the no-risk and 44 from the at-risk population), with a prevalence of 0.32%. Bilateral hearing impairment (BHI) was found in 33 newborns (10 from the no-risk and 23 from the at-risk population), corresponding to 0.17%. Among infants with bilateral hearing impairment, 30.3% had no risk factors. The prevalence of hearing impairment was determined on days 15-30 after birth. The results show that the implementation of a hospital-based, universal neonatal hearing screening programme for babies with and without audiological risk is feasible and effective. The effectiveness of the programme has increased as a function of the years since its inception, with a strong decrease in the referral rate. Further improvement is obtained if the TEOAE measurements

They were classified into four groups ranging from normal hearing to moderate-to-severe hearing loss. All the participants were tested for speech perception in quiet and noisy conditions and for speech perception with time alteration in quiet conditions. Forward- and backward-digit span tests were also conducted to measure the participants’ working memory.Results: 1 As the level of background noise increased, speech perception scores systematically decreased in all the groups. This pattern was more noticeable in the three hearing-impaired groups than in the normal hearing group. 2 As the speech rate increased faster, speech perception scores decreased. A significant interaction was found between speed of speech and hearing loss. In particular, 30% of compressed sentences revealed a clear differentiation between moderate hearing loss and moderate-to-severe hearing loss. 3 Although all the groups showed a longer span on the forward-digit span test than the backward-digit span test, there was no significant difference as a function of hearing loss.Conclusion: The degree of hearing loss strongly affects the speech recognition of babble-masked and time-compressed speech in the elderly but does not affect the working memory. We expect these results to be applied to appropriate rehabilitation strategies for hearing

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.

Full Text Available 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.

Conductive hearing loss is common among children and adults. This study aims at comparing the results of conductive hearing loss in summer and autumn. Puretone audiometry and tympanometry tests were done for all patients who referred to the Iranian-based audiology center of Imam Khomeini Hospital in Ahvaz. Data on the patients with conductive or mixed hearing loss were analyzed. The impacts of season, age, and etiology of the disease were analyzed on the patients who visited the audiology clinic due to the conductive hearing loss in summer and autumn. One hundred and fifty nine patients in summer and 123 patients in autumn had conductive or mixed hearing loss. Their age ranged from four to 82 years, with the average age of 35. The percentage of the patients, with acute otitis media and chronic otitis media (COM), who visited this clinic, was significantly higher than those with middle ear problems. COM and mastoid surgeries rate was higher in summer than autumn among adults. There is no relationship between season and middle ear diseases between children and juveniles, but COM and mastoid problems are more common in summer among adults visiting this clinic. Most of the patients had mild conductive hearing loss and bilateral middle ear impairments.

Disability, Technology and Politics: The entangled experience of being hard of hearing.

2011-03-01

Full Text Available About 10 % of a population have a hearing loss. Combining analytical resources from two interdisciplinary field – Science and Technology Studies and Disability Studies - this thesis investigates the complex interplay between people, technologies and material surroundings. The aim is to learn about how hearing disability becomes ordered in policy making, audiological practice, and everyday life. Disability has traditionally been treated as a physical defect, a problem that can be compensated for utilizing medicine and assistive technologies. Over the last decades, disability policy has undergone a discursive shift. Today, disability is conceptualized as a natural part of societal diversity. Thus, rather than normalizing the disabled individual, society should enable the full inclusion and participation of disabled people in societal life. But how to realize the vision of the universal society? How to translate social rights into empowering medical consultation, enabling technical aids, including material surroundings, and respectful social relations among the people that live and work with hearing disability? Following policy to practice; hearing aids from design to use, and hard of hearing people from the audiological clinic and home, this investigates the transition from disability policy to practice. The result is a comparative, qualitative study of hearing loss in Norway and the Netherlands.

Newborn hearing screening has been successfully implemented worldwide to improve the detection of hearing loss. However, delayed-onset hearing loss subsequent to newborn hearing screening remains a concern. This study aimed to investigate the prevalence of delayed-onset hearing loss in preschool children who previously passed newborn hearing screening in Hubei Province in mid-south China. Preschool children were screened by transient evoked otoacoustic emission (TEOAE) for delayed-onset hearing loss. Children referred after the TEOAE screening were assessed audiologically. Between March 2010 and September 2011, 28 546 preschool children (4.86 ± 1.67 years old), who had passed newborn hearing screening were targeted for screening from four cities in Hubei Province, China. During the study period, 540 children (1.89%) were referred for audiologic assessment and 22 (0.77/1000) of them had permanent delayed-onset hearing loss, including 8 (0.28/1000) with bilateral moderate hearing loss, 10 (0.35/1000) with mild bilateral hearing loss, 2 (0.07/1000) with unilateral moderate hearing loss, and 2 (0.07/1000) with unilateral mild hearing loss. Despite the success of newborn hearing screening, the provision of hearing screening in preschool remains essential for identifying delayed-onset hearing loss.

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.

The purpose of this study was to compare the genotype/phenotype relationship between siblings with identical USH2A pathologic mutations and the consequent audiologic phenotypes, in particular degree of hearing loss (HL). 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 was to define the natural history of hearing loss in Usher syndrome type IIa compared to non-IIa. People with Usher syndrome type II show moderate-to-severe hearing loss, normal balance and retinitis pigmentosa. Several genes cause Usher syndrome type II. Our subjects formed two genetic groups: (1) subjects with Usher syndrome type IIa with a mutation and/or linkage to the Usher IIa gene; (2) subjects with the Usher II phenotype with no mutation and/or linkage to the Usher IIa gene. Four hundred and two audiograms of 80 Usher IIa subjects were compared with 435 audiograms of 87 non-IIa subjects. Serial audiograms with intervals of > or = 5 years were examined for progression in 109 individuals Those with Usher syndrome type IIa had significantly worse hearing thresholds than those with non-IIa Usher syndrome after the second decade. The hearing loss in Usher syndrome type IIa was found to be more progressive, and the progression started earlier than in non-IIa Usher syndrome. This suggests an auditory phenotype for Usher syndrome type IIa that is different from that of other types of Usher syndrome II. Thus, this is to our knowledge one of the first studies showing a genotype-phenotype auditory correlation.

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.

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

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

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.

Improving Hearing Aid Self-Efficacy and Utility Through Revising a Hearing Aid User Guide: A Pilot Study.

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.

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 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.

Full Text Available The objective of this cross-sectional study was to investigate the possibility that the saccule may contribute to human hearing. The forty participants included twenty healthy people and twenty other subjects selected from patients who presented with benign paroxysmal positional vertigo to Audiology Department of Hazrat Rasoul Akram hospital (Tehran, Iran. Assessments comprised of audiological evaluations, cervical vestibular evoked myogenic potentials (cVEMPs, recognition of spoken phonemes in white noise (Rsp in wn, and auditory brainstem response to 500 Hz tone burst (ABR500 HZ. Twenty affected ears with decreased vestibular excitability as detected by abnormal cVEMPs revealed decreased scores of Rsp in wn and abnormal findings of ABR500 HZ. Both unaffected and normal ears had normal results. Multiple comparisons of mean values of cVEMPs and ABR500 HZ between three groups were significant (P<0.05, ANOVA. The correlation between RSP in wn and p13 latencies was significant. The peak-to-peak amplitudes showed significant correlation to RSP in wn. The correlation between RSP in wn and the latencies of n23 was significant. In high-level of noisy competing situations, healthy human saccular sensation can mediate the detection of low frequencies and possibly help in cochlear hearing for frequency and intensity discrimination. So, all human hearing is not cochlear.

Binaural Interference: Quo Vadis?

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.

Full Text Available Introduction Optimization of the selection, adaptation, and benefit of hearing aids is necessary to characterize and manage hearing loss, user expectations, otolaryngologic symptoms, and systemic comorbidities. Objective To compare the occurrence of otologic complaints, systemic diseases, and effective use of hearing aids in men and women with deafness. Methods Patients from a Unified Health System–accredited hearing health service, who reported problems in adapting to their hearing aids, were evaluated by a physician and audiologist. An anamnesis, ENT evaluation, and audiological evaluation were performed. Results During the data collection period, 278 subjects came in for follow-up visits; of these, 61 (21% reported otologic or operational problems with their equipment. The most prevalent type of hearing loss was basocochlear, a characteristic of presbycusis, in both men and women; the most frequently reported comorbidities were hypercholesterolemia (more significant in women and hypertension (more significant in men. Fourteen subjects reported using their device discontinuously, with no significant difference between genders; the reasons for discontinuation of use were itching and ringing, with more complaints from women. Conclusion The incidence of systemic and audiological complaints is high in this population. These patients should be evaluated thoroughly, as resolutions of these complaints can contribute to improving the quality of life and assist in the process of hearing aid fitting.

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

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.

Hiller, Wolfgang; Goebel, Gerhard

2007-01-01

This study evaluates sociodemographic and clinical characteristics of patients reporting discrepant levels of tinnitus loudness and annoyance. 4958 subjects recruited from a national tinnitus association completed a comprehensive screening questionnaire including Klockhoff and Lindblom's loudness grading system and the psychometric Mini-TQ (Tinnitus Questionnaire). There was a moderate correlation of 0.45 between loudness and annoyance. Of the subjects reporting very loud tinnitus, about one third had only mild or moderate annoyance scores. They were not different from those with high annoyance regarding age, gender and tinnitus duration, but annoyance was increased when subjects had additional hearing loss (OR = 1.71), vertigo/dizziness (OR = 1.94) or hyperacusis (OR = 4.96). Another significant predictor was history of neurological disease (OR = 3.16). Subjects reported low annoyance despite high loudness more often if not feeling low/depressed and not considering themselves as victims of their noises. A specific psychological profile was found to characterize annoyed tinnitus sufferers. Permanent awareness of the noises, decreased ability to ignore them and concentration difficulties were reported frequently even when overall annoyance scores were comparatively low. It is concluded that the coexistence of tinnitus with hearing loss, vertigo/dizziness and hyperacusis as complicating otological conditions seems to be of clinical relevance for the prediction of high annoyance levels. Tinnitus loudness and annoyance are not necessarily congruent and should be assessed separately. (c) 2007 S. Karger AG, Basel.

Neonatal hearing screening of high-risk infants using automated auditory brainstem response: a retrospective analysis of referral rates.

The past decade has seen the widespread introduction of universal neonatal hearing screening (UNHS) programmes worldwide. Regrettably, such a programme is only now in the process of nationwide implementation in the Republic of Ireland and has been largely restricted to one screening modality for initial testing; namely transient evoked otoacoustic emissions (TEOAE). The aim of this study is to analyse the effects of employing a different screening protocol which utilises an alternative initial test, automated auditory brainstem response (AABR), on referral rates to specialist audiology services.

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.

São Paulo, Brazil - DERDIC PUC-SP, that took part in a rehabilitation program from 1999 to 2002. METHODS: a retrospective study of 162 files of hearing impaired children between 12mo and 17:6 yrs old, the questionnaire elaborated by The Aural Rehabilitation Forum which occurs annually during the International Audiology Meeting in Brazil was used. RESULTS: the results showed 54% male and 46% female subjects; 60% between 3 and 8:11 years old; 43% had the suspicions of the hearing loss in the first year of life; for 25% of the subjects the diagnostic was carried out just after the suspicions; 34% finished the diagnostic one year after the suspicions; 11% began rehabilitation just after the diagnostic, 54% after a year and 27% more than a year. 32% had unknown etiology, 18% genetic causes, 17% presumed multiple factors, 15% meningitis, 9% congenital rubella. CONCLUSION: the prevalence of unknown etiology shows the need for deepening the diagnosis, and as a routine, carry out genetics, images and laboratories studies, in order to know the etiologies of the hearing loss. Even though after implementing immunization campaigns, rubella was the most prevalent cause of the congenital hearing loss and meningitis was the most prevalent cause of acquired hearing loss. A precious time for the child development was lost because of the time gap between suspicions, diagnostic and rehabilitation.

Perspectives on the Pure-Tone Audiogram.

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

Methods: The Self-assessment for Hearing Screening of the Elderly (SHSE consisted of 20 questions based on the characteristics of presbycusis using a five-point scale: seven questions covered general issues related to sensorineural hearing loss, seven covered hearing difficulty under distracting listening conditions, two covered hearing difficulty with fast-rated speech, and four covered the working memory function during communication. To standardize SHSE, 83 elderly participants took part in the study: 25 with normal hearing, and 22, 23, and 13 with mild, moderate, and moderate-to-severe sensorineural hearing loss, respectively, according to their hearing sensitivity. All were retested 3 weeks later using the same questionnaire to confirm its reliability. In addition, validity was assessed using various hearing tests such as a sentence test with background noise, a time-compressed speech test, and a digit span test. Results: SHSE and its subcategories showed good internal consistency. SHSE and its subcategories demonstrated high test–retest reliability. A high correlation was observed between the total scores and pure-tone thresholds, which indicated gradually increased SHSE scores of 42.24%, 55.27%, 66.61%, and 78.15% for normal hearing, mild, moderate, and moderate-to-severe groups, respectively. With regard to construct validity, SHSE showed a high negative correlation with speech perception scores in noise and a moderate negative

The aim of this study was to evaluate the effectiveness of bilateral cochlear implantation (CI) compared with unilateral CI for deaf children in the context of the Republic of Kazakhstan health system. Methods. A literature search was conducted, using the PubMed, Cochrane, and Embase data bases for studies that compared the effectiveness of bilateral and unilateral CI in children. The search included English language, publications from 2002-2012. Two reviewers independently evaluated all relevant studies. Administrative data relevant to CI in Kazakhstan were obtained from the Ministry of Health. Three relevant systematic reviews and an health technology assessment report were found. There was evidence of incremental benefits from bilateral CI but the quality of the available studies was poor and there was little information on longer term outcomes. No conclusions could be drawn regarding later incremental improvements to speech perception, learning, and quality of life. To date, in the Republic of Kazakhstan there is not full coverage of audiological screening due to the lack of medical equipment. This leads to late detection of hearing-impaired children and a long rehabilitation period, requiring more resources. Age of implantation in children is late and only a small minority attend general schools. The clinical effectiveness of bilateral CI, an expensive health technology, requires further study. Given the current situation in Kazakhstan with audiological screening and access to unilateral CI, there appeared to be other priorities for improving services for children with profound hearing impairment.

The purpose of the study was to investigate the etiological factors and the audiological data of different types of inner ear malformations, which the authors thought might be helpful in elucidating the inter-relation among malformations and shedding light on pathogenesis. Retrospective study from 1998 to 2002 at a tertiary care university hospital. One hundred sixty consecutive children with a total of 302 affected ears undergoing high-resolution computed tomography of the temporal bone for sensorineural hearing loss were enrolled. The image results were correlated with causes and origins, hearing loss patterns, hearing levels, and audiogram configurations. Inner ear malformation was present in 114 (38%) ears. The most common malformations were enlarged vestibular aqueduct, incomplete partition of cochlea (Mondini dysplasia), large vestibule, and semicircular canal dysplasia, presenting either as isolated finding or in combination. Eighty-four (74%) ears had abnormalities confined to these four malformations; only 30 (26%) ears showed other malformations. Patients with complex of enlarged vestibular aqueduct, Mondini dysplasia, large vestibule, and semicircular canal dysplasia (EMVS complex) demonstrated a significantly higher incidence of fluctuating hearing loss (93%) and a better hearing level compared with those with other malformations. Homogeneity in audiological features among these four malformations was also disclosed. The authors identified a distinct clinical entity, the EMVS complex, which is characterized by fluctuating hearing loss and a better hearing level. The authors proposed that malformations belonging to this complex result from a common pathogenetic mechanism.

The Speech, Spatial and Qualities of Hearing Scale (SSQ) is applied worldwide as a highly reliable tool for the characteristic of the quality of life and subjective sensations of the patients presenting with hearing impairment as well as for the estimation of the efficiency of hearing aids. The objective of the present study was to validate and adapt the Russian language version of the SSQ questionnaire (SSQrus) for its application in the audiological practice under conditions of this country. After the cultural and language adaptation of SSQrus, it was validated by means of repeat interviewing of three groups of the respondents (a total of 93 subjects with normal, moderately and severely impaired hearing). The results of the validation give evidence of the high reliability of the modified questionnaire. Specifically, high reproducibility of the data estimated from the results of the second interview has been demonstrated (r=0.85--0.99). High sensitivity of SSQruswas confirmed by the agreement between the results of the estimation (in scores) and the degree of the observed loss of hearing. The estimates obtained by the application of the SSQrus questionnaire are comparable with those reported by the foreign authors. It is concluded that the SSQrus questionnaire can be used in routine audiological practice as an additional diagnostic instrument for the estimation of hearing problems experienced by a patient, monitoring efficiency of therapy and surgical treatment of hearing impairment, improvement of hearing aids, and hearing dysfunction research.

We used a novel approach allowing participants in this study to self-monitor their hearing sensitivity to familiar sounds in the environment. The objective of this approach was to establish whether participants in the 80-89 and 90-99 age groups would recognize the degree of their hearing impairment. It was our hope that participants would value audiology treatment and that it would improve their quality of life over a short period. The pilot study took place in a clinical environment where participants answered survey questions before and after audiology treatment, which pertained to their hearing impairment, morale, social support, and life satisfaction. Caregivers were included in the research to rate and record participants' problem behaviors (e.g., shouting, anger, agitation, repetitive speech dialog, and depression) before, during, and after treatment. This research validates other scientists' findings that annoying problem behaviors may actually be the result of hearing loss because of a person's inability to recognize speech. The pilot study shows that participants with mild dementia adapted well to speech and sounds in the natural environment without agitation as well as to management of hearing aids within a 30-day period. The participants with moderate dementia were slower to adapt. All participants with dementia required the cooperation of their caregivers to maintain hygiene of ear canals and hearing aids and insertion. This study suggests that the sooner people receive treatment for hearing loss, the quicker they are to recognize speech and to master hearing aid technology.

To verify the aspects of technical quality and the content of websites on neonatal hearing screening in Portuguese. Eighteen audiologists, invited to participate according to the inclusion criteria, selected descriptors of websites for research using the Delphi technique. Later, they were fed into Google Trends to get the possible terms to be used by parents in finding information on the Internet about the subject. They were then fed into Google to search the websites. The following assessment instruments were used: list of topics on newborn hearing screening, Flesch Reading Ease Score Formula, Health-Related Web Site Evaluation Emory Form, and PageRank. The most discussed topics in the 19 websites were on the objectives and benefits of neonatal hearing screening, as well as the process of audiological diagnosis. The least discussed were about the false-negative result, development of hearing and language, false-positive results, audiologic, interpretation of results - "Pass"/"Do not pass", retest, and protocol. Difficult reading level was prevalent, with aspects of technical quality considered the best quality-related content, audience, navigation, and structure. The results also showed there is no culture of inserting links on Brazilian national websites, so they had little relevance on Google. The sites differed in the aspects addressed because there is a need to revise the reading level of the content and quality of the technical aspects regarding the accuracy and timeliness of information, authorship, and links.

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.

The bone-anchored hearing aid

DEFF Research Database (Denmark)

Foghsgaard, Søren

2014-01-01

The bone-anchored hearing aid (Baha) was introduced in 1977 by Tjellström and colleagues and has now been used clinically for over 30 years. Generally, the outcomes are good, and several studies have shown improved audiological- and quality of life outcomes. The principle of the Baha is, that sou...... vibrations are led directly to the inner ear via the mastoid bone, bypassing the middle ear. This is achieved via an osseointegrated implant and a skin-penetrating abutment. Studies report high success rates and a majority of complications as typically minor in nature....

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.

prevalent type of meningitis as cause of hearing impairment. METHODS: Two hundred and eighty nine caregivers of children who were diagnosed with pyogenic meningitis between 28 days and 24 months, and had been admitted at Hospital Couto Maia (HC Maia between January 2002 and December 2003 were contacted. The sample was composed of 55 children that survived with or without evident sequelae, who attended audiological and neurological evaluation. A complete audiological evaluation was carried out, including a subjective and objective battery of evaluation tests, using standardized instruments for investigation of children's hearing. RESULTS: The age range of the subjects when the audiological evaluation was carried out varied from two to five years. Hearing impairment was detected in 29% of the sample, characterizing, mostly, a profound bilateral neurosensory hearing loss. The main neurological sequelae found were: epilepsy, hemiparesy, hydrocephaly, dysphasia, and hyperactivity. CONCLUSION: The results indicate the need for audiological monitoring and neurological follow-up in children with previous history of pyogenic meningitis, especially those infected in early ages, seeking to identify possible hearing impairments and to intervene as soon as possible, through specialized intervention, prothetization, and oral language rehabilitation.

Full Text Available Hearing evaluation usually includes hearing threshold assessment, middle ear function, and word recognition tests that lead to an accurate result of peripheral and central auditory system. However, they have some limitations because they cannot fully encompass all aspects of hearing loss problems. Using self-assessment approach, via a questionnaire or telephone survey, is one of the easiest methods to study hearing loss in population. In this research, 60 nursing home residents (27 females and 33 males ranging from 55 to 85 years with a mean age of were studied via completing self-assessment questionnaire by the elderly cases (NHHI self-version and the other one was filled by the nursing home personnel (NHHI staff-version. The effects of the hearing loss level on the self- and staff-version scores indicated that there is a significant relationship between self- and staff-version with hearing loss levels ( in male and female. Results from this study demonstrate the usefulness of NHHI questionnaire for evaluating hearing handicap of aged people and it may be a useful adjunct in setting up treatment and determining proper care.

Conventional audiometry is the gold standard for quantifying and describing hearing loss. Alternative methods become necessary to assess subjects who are too young to respond reliably. Auditory evoked potentials constitute the most widely used method for determining hearing thresholds objectively; however, this stimulus is not frequency specific. The advent of the auditory steady-state response (ASSR) leads to more specific threshold determination. The current study describes and compares ASSR, auditory brainstem response (ABR) and conventional behavioural tone audiometry thresholds in a group of infants with various degrees of hearing loss. A comparison was made between ASSR, ABR and behavioural hearing thresholds in 35 infants detected in the neonatal hearing screening program. Mean difference scores (±SD) between ABR and high frequency ABR thresholds were 11.2 dB (±13) and 10.2 dB (±11). Pearson correlations between the ASSR and audiometry thresholds were 0.80 and 0.91 (500Hz); 0.84 and 0.82 (1000Hz); 0.85 and 0.84 (2000Hz); and 0.83 and 0.82 (4000Hz). The ASSR technique is a valuable extension of the clinical test battery for hearing-impaired children.

Remote hearing aid fitting: Tele-audiology in the context of Brazilian Public Policy

Science.gov (United States)

Penteado, Silvio Pires; Ramos, Sueli de Lima; Battistella, Linamara Rizzo; Marone, Silvio Antonio Monteiro; Bento, Ricardo Ferreira

2012-01-01

Summary Introduction: Currently, the Brazilian government has certificated nearly 140 specialized centers in hearing aid fittings through the Brazilian National Health System (SUS). Remote fitting through the Internet can allow a broader and more efficient coverage with a higher likelihood of success for patients covered by the SUS, as they can receive fittings from their own homes instead of going to the few and distant specialized centers. Aim: To describe a case of remote fitting between 2 cities, with revision of the literature. Method: Computer gears, a universal interface, and hearing aids were used. Case study: An audiologist located in a specialized center introduced a new hearing aid and its fitting procedure to a remote center (200 km away). The specialized center helped the remote center in fitting a hearing aid in 2 patients, and performed fitting in one of its own patients. The whole process was done through the Internet with audio and video in real time. Results: Three patients were fitted remotely. Three audiologists were remotely trained on how to fit the hearing aids. Conclusions: Remote fitting of hearing aids is possible through the Internet, as well as further supplying technical training to a remote center about the fitting procedures. Such a technological approach can help the government advance public policies on hearing rehabilitation, as patients can be motivated about maintaining their use of hearing aids with the option to ask for help in the comfort of their own homes.

2016-10-01

Full Text Available Abstract Background Bone conduction devices are widely used and indicated in cases of conductive, mixed or single sided deafness where conventional hearing aids are not indicated or tolerated. Percutaneous bone-conduction devices gave satisfactory hearing outcomes but were frequently complicated by soft tissue reactions. Transcutaneous bone conduction devices were developed in order to address some of the issues related to the skin-penetrating abutment. The aim of this article is to present a systematic review of the indications, surgical technique and audiological, clinical and functional outcomes of the BAHA Attract device reported so far. Methods A systematic computer-based literature search was performed on the PubMed database as well as Scopus, Cochrane and Google Scholar. Out of 497 articles, 10 studies and 89 reported cases were finally included in our review. Results The vast majority of implanted patients were satisfied with the aesthetics of the device scoring highly at the Abbreviated Profile of Hearing Aid Benefit, Glasgow Benefit Inventory and Client Oriented Scale of Improvement. Overall, hearing outcomes, tested by various means including speech in noise, free field hearing testing and word discrimination scores showed a significant improvement. Complications included seroma or haematoma formation, numbness around the area of the flap, swelling and detachment of the sound processor from the external magnet. Conclusions The functional and audiological results presented so far in the literature have been satisfactory and the complication rate is low compared to the skin penetrating Bone Conduction Devices. Further robust trials will be needed to study the long-term outcomes and any adverse effects.

Using Bioacoustical Methodologies to Evaluate Equine Hearing Capabilities and Cognition

Science.gov (United States)

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.

Described is a case series of clinical findings in children with persistent conductive or mixed hearing loss following tympanostomy tube placement for serous otitis media. Retrospective chart review. Tertiary pediatric hospital. Medical records of thirty-nine children who were referred for either conductive or mixed hearing loss post-tympanostomy tube placement were reviewed for clinical histories, physical examinations, audiological evaluations, diagnostic studies, consultations, and surgical findings. Approval was obtained from the Boston Children's Hospital Institutional Review Board. Causes of hearing loss included ossicular abnormalities, cochlear abnormalities, 'third window' effects, cholesteatomas, genetic syndromes, and unknown causes. In four patients with isolated mild low-frequency conductive hearing loss, the cause was the presence of functional tubes. All patients diagnosed with a genetic syndrome had bilateral hearing loss. Patients with mixed hearing loss were diagnosed with cochlear abnormalities, 'third window' effects, or genetic syndromes. Computed tomography led to diagnosis in sixteen of twenty-five patients. Vestibular-evoked myogenic potential testing suggested a diagnosis in three of four patients. In children with persistent hearing loss following tympanostomy tube placement, identifying the laterality and type of hearing loss appears to be of importance in diagnosis. Patients with bilateral hearing loss should be considered for genetic testing, given the possibility of a syndrome. Patients identified with a mixed hearing loss should be evaluated for inner ear anomalies. Patients with mild, low-frequency hearing losses should be monitored audiologically and investigated further only if the hearing loss progresses and/or there is no resolution following tube extrusion.

Bastos, Bárbara Guimarães

2011-10-01

Full Text Available Introduction: The process of education of a patient aims to improve knowledge and skill of the patient and/or family, in a way to influence attitudes and behaviors needed to maintain or improve health. Must be a integral part of interpersonal communication between health professionals and patients, and this can happen through interpersonal communication and various other means such as pamphlets, manuals and, more recently, computer resources. Goal: This update article approach the patient education and the internet potential for this process, still presenting some initiatives in the audiology área. Discussion: The informations, related to health are popular in the internet, and include interactive websites, portals, e-mails, telehealth aplications, and others. The education of the patients supported by the internet can help to solve a big ethical, political and economic issue: the problem to conciliate the needs and the expectations of the patients with the characteristics and limitations of the health system. Although the use of internet in the education of the patient is promising, this is not a solution to be used without careful planning, monitoring and evaluation. In audiology there are few initiatives with the use of e-mails and websites for complement of the patient education. Final Considerations: The health professionals, including the speech therapists, must check if their patients use internet resources, recognize that behavior change and prepare not only to discuss the information obtained with the patient, but also suggest websites with reliable information and help them to evaluate the quality of the information available online.

Hereditary forms of hearing impairment (HI) caused by GJB2 (Cx26) mutations are the frequent sensory disorders registered among newborns in various human populations. In this study, we present data on the molecular, audiological and population features of autosomal recessive deafness 1A (DFNB1A) associated with the donor splicing site IVS1+1G>A mutation of GJB2 gene in Yakut population isolate of the Sakha Republic (Yakutia) located in Eastern Siberia (Russian Federation). The Yakut population exhibits high frequency of some Mendelian disorders, which are rare in other populations worldwide. Mutational analysis of GJB2 gene in 86 unrelated Yakut patients with congenital HI without other clinical features has been performed. In this study, we registered a large cohort of Yakut patients homozygous for the IVS1+1G>A mutation (70 unrelated deaf subjects in total). Detailed audiological analysis of 40 deaf subjects with genotype IVS1+1G>A/IVS1+1G>A revealed significant association of this genotype with mostly symmetrical bilateral severe to profound HI (85% severe-to-profound HI versus 15% mild-to-moderate HI, PA mutation (11.7%) has been found in Yakut population. Reconstruction of 140 haplotypes with IVS1+1G>A mutation demonstrates the common origin of all mutant chromosomes found in Yakuts. The age of mutation was estimated to be approximately 800 years. These findings characterize Eastern Siberia as the region with the most extensive accumulation of the IVS1+1G>A mutation in the world as a result of founder effect.

Gómez Toledo, Verónica; Gutiérrez Farfán, Ileana; Verduzco-Mendoza, Antonio; Arch-Tirado, Emilio

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.

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

2016-12-01

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.

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.

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

Science.gov (United States)

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.

Bilateral hearing is important for learning, development, and function in complex everyday environments. Children with conductive and mixed hearing loss (HL) have been treated for years with percutaneous coupling through an abutment, which achieves powerful output, but the implant site is susceptible to skin reactions and trauma. To overcome these complications, transcutaneous magnetic coupling systems were recently introduced. The purpose of the study was to evaluate whether the new transcutaneous magnetic coupling is an effective coupling paradigm for bone-conduction hearing aids (BCHAs). We hypothesized that magnetic coupling will (1) have limited adverse events, (2) provide adequate functional gain, (3) improve spatial hearing and aid listening in everyday situations, and (4) provide satisfactory outcomes to children and their families given one normal hearing ear. Retrospective analysis of audiological outcomes in a tertiary academic pediatric hospital. Nine children aged 5-17 yr with permanent unilateral conductive HL (UCHL) or mixed HL were implanted with a transcutaneous magnet-retained BCHA. Average hearing thresholds of the better and implanted ears were 12.3 ± 11.5 dB HL and 69.1 ± 11.6 dB HL, respectively, with a 59.4 ± 4.8 dB (mean ± standard deviation) conductive component. Data were extracted from audiology charts of the children with permanent UCHL or mixed HL who qualified for a surgically retained BCHA and agreed to the magnetic coupling. Outcomes were collected from the 3- to 9-mo follow-up appointments, and included surgical complications, aided audiometric thresholds with varying magnet strength, speech performance in quiet and noise, and patient-rated benefit and satisfaction using questionnaires. Repeated measures analysis of variance was used to analyze audiometric outcomes, and nonparametric tests were used to evaluate rated benefit and satisfaction. All nine children tolerated the device and only one child had discomfort at the wound

In underserved areas, it is crucial to investigate ways of increasing access to hearing health care. The community health worker (CHW) is a model that has been applied to increase access in various health arenas. This article proposes further investigation into the application of this model to audiology. To assess the feasibility of training CHWs about hearing loss as a possible approach to increase accessibility of hearing health support services in an underserved area. A specialized three-phase training process for CHWs was developed, implemented, and evaluated by audiologists and public health researchers. The training process included (1) focus groups with CHWs and residents from the community to raise awareness of hearing loss among CHWs and the community; (2) a 3-hr workshop training to introduce basic topics to prepare CHWs to identify signs of hearing loss among community members and use effective communication strategies; and (3) a 24-hr multisession, interactive training >6 weeks for CHWs who would become facilitators of educational and peer-support groups for individuals with hearing loss and family members. Twelve Spanish-speaking local CHWs employed by a federally qualified health center participated in a focus group, twelve received the general training, and four individuals with prior experience as health educators received further in-person training as facilitators of peer-education groups on hearing loss and communication. Data was collected from each step of the three-phase training process. Thematic analysis was completed for the focus group data. Pre- and posttraining assessments and case study discussions were used to analyze results for the general workshop and the in-depth training sessions. CHWs increased their knowledge base and confidence in effective communication strategies and developed skills in facilitating hearing education and peer-support groups. Through case study practice, CHWs demonstrated competencies and applied their learning

Communication disorders have been acknowledged as a major public health issue because they compromise early childhood development, restrict vocational attainment and undermine the economic well being of the society. The aim of this study is to determine the pattern of communication disorders among children in a developing country and the requisite intervention services. This prospective study was conducted in Lagos University Teaching Hospital, Lagos between January 2002 and June 2003 among children aged 6 months to 15 years that presented in the audiology clinic of the hospital with communication disorders. All the patients had neurological, otolaryngological, audiological and speech evaluations. A total of 184 patients were seen during the period out of whom 136 (74%) were between the ages of 6-47 months. Hearing impairment was documented in 120 (65.2%) children, speech disorders in 56 (30.4%), rhinolalia 2.2% and stuttering 2.2%. Of those with hearing impairment, 70% had delayed speech and language. Among children with speech disorders 78.6% had specific language impairment (SLI). Aetiological factors recorded for the communication disorders were seizures 10.9%, measles 8.7% meningitis 8.7%, birth asphyxia 6.5%, otitis media with effusion (OME) 4.3%, kernicterus 4.3%, congenital deformity 4.3%, ototoxicity 2.2%, cerebral palsy 2.2%, and undetermined causes 47.9%. Hearing impairment is the commonest communication disorder. Early detection and appropriate follow up is recommended for all children in their first year of life. The role of parents and caregivers in seeking early help should be strengthened while capacity building for the training of more audiologists and speech therapists should be pursued rapidly.

Full Text Available Abstract Background When evaluating hearing rehabilitation, it is reasonable to use self-report questionnaires as outcome measure. Questionnaires used in audiological research are developed and validated for the paper-and-pencil format. As computer and Internet use is increasing, standardized questionnaires used in the audiological context should be evaluated to determine the viability of the online administration format. The aim of this study was to compare administration of questionnaires online versus paper- and pencil of four standardised questionnaires used in hearing research and clinic. We included the Hearing Handicap Inventory for the Elderly (HHIE, the International Outcome Inventory for Hearing Aids (IOI-HA, Satisfaction with Amplification in Daily Life (SADL, and the Hospital Anxiety and Depression Scale (HADS. Methods A cross-over design was used by randomly letting the participants complete the questionnaires either online or on paper. After 3 weeks the participants filled out the same questionnaires again but in the other format. A total of 65 hearing-aid users were recruited from a hearing clinic to participate on a voluntary basis and of these 53 completed both versions of the questionnaires. Results A significant main effect of format was found on the HHIE (p Conclusions For three of the four included questionnaires the participants’ scores remained consistent across administrations and formats. For the fourth included questionnaire (HHIE a significant difference of format with a small effect size was found. The relevance of the difference in scores between the formats depends on which context the questionnaire is used in. On balance, it is recommended that the administration format remain stable across assessment points.

Active middle ear implant can be used in children and adolescents with congenital hearing loss. The authors report their experience with the semi implantable Medel Vibrant Soundbridge(®) (VSB) in the audiologic rehabilitation of such patients. In this retrospective study, audiological and surgical data of 10 children (10.5±4 years) implanted with 12 VSB in 2 tertiary cares ENT Departments were analysed. Two children with bilateral external auditory canal (EAC) atresia and mixed hearing loss (mean air conduction (AC) thresholds=65dB HL) were bilaterally implanted. Eight children presented with microtia associated with EAC atresia bilaterally (n=3) and unilaterally (n=5). All of them had a conductive hearing loss in the implanted ear (mean (AC) thresholds were 58.75dB HL preoperatively). The Floating Mass Transducer was crimped on the long process of the incus (n=8) or on the suprastructure of the stapes (n=4). There were no intra- or postoperative surgical complications. All the children wore their implants after 5 weeks. Postoperative mean bone conduction (BC) thresholds were unchanged. The mean aided thresholds with VSB (four frequencies warble tones at 0.5, 1, 2 and 4 kHz) were 28dB HL (± 10). Word discrimination threshold in quiet conditions in free field with the VSB unilaterally activated was 50% at 38dB SPL (± 9). The results indicate that satisfaction of the children and their parents is very encouraging but surgeons should be cautious with this new approach in relation to the pinna reconstruction and to possible risks to inner ear and facial nerve.

Full Text Available 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.

Counseling Issues: Addressing Behavioral and Emotional Considerations in the Treatment of Communication Disorders.

2018-02-06

Counseling is an important fundamental professional activity and an established component of the speech-language pathology/audiology scope of practice as documented by the American Speech-Language-Hearing Association (2004a, 2016a). Appropriate incorporation of counseling into practice can optimize service provision, help address comorbid behavioral and emotional reactions to communication disorders, and enhance prognosis. Practitioner insecurity in incorporating counseling into practice has been documented by Phillips and Mendel (2008), as well as Atkins (2007). This tutorial seeks to present general counseling constructs and treatment applications primarily utilizing a humanistic counseling perspective. This tutorial incorporated relevant publications from communication disorders and counseling psychology literature databases over a 3-year period. The tutorial evolved through interviews with practicing speech-language pathology practitioners and educators and was undertaken to provide transparency and clarity to support the assertions and recommendations offered. This tutorial organizes and presents general counseling considerations along with specific suggestions, which can help practitioners who are seeking to expand their understanding, skill, and confidence in incorporating counseling into their practice. The tutorial identifies some of the potential and impactful comorbid emotional and behavioral responses to experiencing a communication disorder and/or to the treatment process for the communication disorder issue(s). Theoretically grounded considerations for mitigating such potentially impactful responses are offered. Continued and enhanced efforts may be necessary to meet American Speech-Language-Hearing Association's mandate for universal incorporation of empirically supported counseling approaches and in advancing universal speech-language pathology/audiology training in this area. It is hoped that this tutorial serves as an initial guide for addressing

How well can centenarians hear?

Full Text Available 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.

Full Text Available Background. The use of generic medicines to reduce healthcare costs has become a mandated policy in South Africa. An increase in the use of generics can be achieved through improved knowledge, attitudes and perceptions of generic medicine among healthcare professionals. Objective. To explore knowledge, attitudes and perceptions among final-year health science students on generic medication. Methods. A cross-sectional survey was carried out among the final-year audiology, dental therapy, pharmacy, physiotherapy, occupational therapy, optometry, speech-language and sport science students enrolled at the University of KwaZulu-Natal. A questionnaire was used as the study tool, developed using information adapted from literature reviews. Data analysis was completed using Statistical Package for the Social Sciences (SPSS version 21, and computed using descriptive statistics. Results. Total number of participants was 211, as follows: audiology (n=14, dental therapy (n=15, pharmacy (n=81, physiotherapy (n=41, occupational therapy (n=6, optometry (n=25, speech-language (n=6 and sport science (n=23. A total of 90.0% of students had heard of generic medicines, with 20.9% of them agreeing that generic medicines are less effective than brand-name medicines. Concerning safety, 30.4% believed that brand-name medicines are required to meet higher safety standards than generic medicines. Regarding the need for information on issues pertaining to safety and efficacy of medicines, 53.3% of participants felt that this need was not being met. Conclusion. All groups had knowledge deficits about the safety, quality and efficacy of generic medicines. The dissemination of information about generic medicines may strengthen future knowledge, attitudes and perceptions.

Full Text Available Introduction: The vascular compression by redundant vessels under the VIII cranial nerves has been studied since the 80's, and many authors proposed correlations between the compression and the otoneurological findings (vertigo, tinnitus, hypoacusis, audiometry and electrophysiological findings. Objective: Analyze and correlate the different signs and otoneurological symptoms, the audiological findings and its incidence over individuals with Vascular Loop (VL diagnosis of VIII cranial nerves by magnetic resonance imaging (MRI. Method: Retrospective study through the analysis of medical records of 47 patients attended in the otoneurology clinic of Clinical Hospital of UFPR. All the patients have MRI exams with compatible pictures of VL of the VIII cranial nerves. Results: The tinnitus was the most frequent symptom, in 83% of the patients, followed by hypoacusis (60% and vertigo (36%. The audiometry presented alterations in 89%, the brainstem evoked auditory potential in 33% and the vecto-electronystagmography in 17% of the patients. Was not found statistically significant relation between the buzz or hypoacusis, and the presence of VL in MRI. Only 36% of patients had complaints of vertigo, the main symptom described in theory of vascular compression of the VIII pair of nerve. As in the audiometry and in brainstem evoked auditory potential was not found a statistically significant relation between the exam and the presence of the VL in the RMI. Conclusion: The results show independence between the findings of the RMI, clinical picture and audiological results (p>0,05 suggesting that there are no exclusive and direct relation between the diagnosis of vascular loop in the MRI and the clinical picture matching.

To analyze the incidence and degree of sensorineural hearing loss (SNHL) resulting from different radiation techniques, fractionation dose, mean cochlear radiation dose (D mean ), and total cisplatin dose. In all, 29 children with medulloblastoma (58 ears) with subclinical pretreatment hearing thresholds participated. Radiotherapy (RT) and cisplatin had been applied sequentially according to the HIT MED Guidance. Audiological outcomes up to the latest follow-up (median 2.6 years) were compared. Bilateral high-frequency SNHL was observed in 26 patients (90%). No significant differences were found in mean hearing threshold between left and right ears at any frequency. A significantly better audiological outcome (p < 0.05) was found after tomotherapy at the 6 kHz bone-conduction threshold (BCT) and left-sided 8 kHz air-conduction threshold (ACT) than after a combined radiotherapy technique (CT). Fraction dose was not found to have any impact on the incidence, degree, and time-to-onset of SNHL. Patients treated with CT had a greater risk of SNHL at high frequencies than tomotherapy patients even though D mean was similar. Increase in severity of SNHL was seen when the total cisplatin dose reached above 210 mg/m 2 , with the highest abnormal level found 8-12 months after RT regardless of radiation technique or fraction dose. The cochlear radiation dose should be kept as low as possible in patients who receive simultaneous cisplatin-based chemotherapy. The risk of clinically relevant HL was shown when D mean exceeds 45 Gy independent of radiation technique or radiation regime. Cisplatin ototoxicity was shown to have a dose-dependent effect on bilateral SNHL, which was more pronounced in higher frequencies. (orig.) [de

The objective of this study is to report the surgical outcome after middle fossa approach (MFA) plugging in patients suffering from a superior semi-circular canal dehiscence (SCD) syndrome. This is a retrospective case review. Tertiary referral center. Sixteen ears in 13 patients with a SCD syndrome suffering from severe and disabling vestibular symptoms with a bony dehiscence on CT scan >3 mm and decreased threshold of cervical vestibular evoked potentials (cVEMPs). We assessed preoperatively: clinical symptoms, hearing, cVEMPs threshold, size of dehiscence and videonystagmography (VNG) with caloric and 100 Hz vibratory tests. Postoperatively, we noted occurrences of neurosurgical complication, evolution of audiological and vestibular symptoms, and evaluation of cVEMP data. Tullio's phenomenon was observed in 13 cases (81.3 %) and subjectively reported hearing loss in seven (43.7 %). All patients were so disabled that they had to stop working. No neurosurgical complications were observed in the postoperative course. In three cases (16.6 %), an ipsilateral and transitory immediate postoperative vestibular deficit associated with a sensorineural hearing loss (SNHL) was noted, which totally resolved with steroids and bed rest. All patients were relieved of audiological and vestibular symptoms and could return to normal activity with a mean follow-up of 31.1 months (range 3-95). No patient had residual SNHL. cVEMPs were performed in 14 ears postoperatively and were normalized in 12 (85.7 %). Two of the three patients operated on both sides kept some degree of unsteadiness and oscillopsia. MFA plugging of the superior semi-circular canal is an efficient and non-hearing deteriorating procedure.

In this study, we aimed to evaluate the audiovestibular functions in the patients with ankylosing spondylitis (AS). This prospective study was performed in collaboration by the Otolaryngology and Rheumatology Departments of Bozok University School of Medicine between May 1, 2012, and January 1, 2013. We studied 80 subjects consisting of 40 AS patients (37 men and 3 women) in whom the diagnosis confirmed by the criteria of New York and 40 healthy controls (35 men and 5 women). All participants were evaluated by routine audiologic (including tympanometric evaluation, pure-tone audiograms, speech tests) and vestibular studies (including spontaneous nystagmus, gaze, optokinetic, saccadic movements, smooth pursuit, caloric test and Dix-Hallpike tests). The tympanometric values did not show a statistically significant difference between the AS group and the healthy subjects (p > 0.05). At low frequencies (250, 500, 1,000, and 2,000 Hz) pure-tone audiologic evaluations also proved statistically non-significant results at mean air conduction thresholds (ACT) and bone conduction thresholds (BCT) between the AS and control groups (p > 0.05). At high frequencies (4,000, 6,000, and 8,000 Hz), the ACTs and BCTs in AS group were lower than control group which was statistically significant (p 0.05). The comparison of smooth pursuit and Dix-Hallpike tests reached statistical significance (p VNG) revealed central abnormalities in 7 patients (17.5 %), peripheral abnormalities in 16 patients (40 %), and mixed abnormalities in 3 patients (7.5 %). Our findings suggest a possible association between AS and audiovestibular system dysfunction. We assume that the hearing and vestibular disturbances in AS are more prevalent than previously recognized.

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.

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.

Data mining of audiology patient records: factors influencing the choice of hearing aid type

Science.gov (United States)

2012-01-01

Background This paper describes the analysis of a database of over 180,000 patient records, collected from over 23,000 patients, by the hearing aid clinic at James Cook University Hospital in Middlesbrough, UK. These records consist of audiograms (graphs of the faintest sounds audible to the patient at six different pitches), categorical data (such as age, gender, diagnosis and hearing aid type) and brief free text notes made by the technicians. This data is mined to determine which factors contribute to the decision to fit a BTE (worn behind the ear) hearing aid as opposed to an ITE (worn in the ear) hearing aid. Methods From PCA (principal component analysis) four main audiogram types are determined, and are related to the type of hearing aid chosen. The effects of age, gender, diagnosis, masker, mould and individual audiogram frequencies are combined into a single model by means of logistic regression. Some significant keywords are also discovered in the free text fields by using the chi-squared (χ2) test, which can also be used in the model. The final model can act a decision support tool to help decide whether an individual patient should be offered a BTE or an ITE hearing aid. Results The final model was tested using 5-fold cross validation, and was able to replicate the decisions of audiologists whether to fit an ITE or a BTE hearing aid with precision in the range 0.79 to 0.87. Conclusions A decision support system was produced to predict the type of hearing aid which should be prescribed, with an explanation facility explaining how that decision was arrived at. This system should prove useful in providing a "second opinion" for audiologists. PMID:22595091

Full Text Available This case can be placed in a neurologic classification. The patient is a child with learning disability in school activities. He was first referred to an audiological clinic because of a central auditory processing disorder (CAPD. His mother has noticed several hearing problems and this led us to the evaluations for his central auditory processing disorder. He has problems in hearing speech in noise and speech processing and need his friends repeat words during communication. no vestibular disorder was noticed nor any localization problem. The child has a good progress in school and only suffered problems in reading tasks. Intelligence quotient(IQ was also normal.

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.

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.

We herein report a case of posterior semicircular canal dehiscence (SCD) syndrome who had been audiologically followed up for eight years. The patient originally had sensorineural hearing loss. The audiogram had gradually transformed to pure conductive hearing loss. The posterior SCD was identified in CT scan. The reported case showed the possibility to distinguish the mechanism at play underlying the typical conductive hearing loss in SCD patients by tracing the transition of the hearing loss pattern. This information is of much help to predict the hearing outcomes if surgical intervention were chosen for the treatment. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Advances in the radiological diagnosis of VIIIth nerve tumours

1982-01-01

Where there is suspicion from the audiological and vestibular findings of an VIIIth nerve tumour, radiographs of the skull and of the petrous bones (Stenvers) should be obtained. This should be followed by computer tomography with intravenous contrast medium (a plain series can be omitted in these cases). A negative or indefinite scan should be followed by CT performed after air insufflation. Vertebral angiography is valuable as a pre-operative investigation for tumours larger than 3 cm. Ordinary tomography of the petrous bone in sagittal, lateral or Stenvers projection or cisternography with air, oily or aqueous contrast medium need not be carried out. (orig.) [de

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

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

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.

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

Science.gov (United States)

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

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.

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.

The Effect of the Cholesterol Levels on Noise-Induced Hearing Loss.

Demir, Mehmet Gokhan; Aydin, Sedat

2018-01-01

Introduction  Noise-induced hearing loss (NIHL), which is one of the most common occupational diseases among industrialized populations, is associated with longstanding exposure to high levels of noise. The pathogenesis of NIHL is not clear, but some genes and their activity at the tissue level have been investigated. Hypercholesterolemia, which can disturb the microcirculation, can be one of the underlying pathologies in hearing loss. Objective  To investigate the relationship between NIHL and hypercholesterolemia. Methods  The study group was selected among workers who had an occupational exposure of 85 dB of noise for at least 10 years. The audiologic assessment was recorded at seven frequencies (500 Hz, 1,000 Hz, 2,000 Hz, 3,000 Hz, 4,000 Hz, 6,000 Hz and 8,000 Hz). A total of 456 workers were included in the study and divided into two groups: the control group (252 patients) and the NIHL group (204 patients). After the audiologic measurement, blood samples were taken and investigated for blood cholesterol levels. According to these results, the groups were compared. Results  Both groups were similarly distributed regarding age and occupational exposure time ( p  > 0.05). We could not detect any association between cholesterol levels and noise-induced hearing loss ( p   0.05). Conclusion  Noise-induced hearing loss is still a common occupational problem that can be prevented by hearing conservation programs and occupational health and safety training. Still, we know little about the relationship between NIHL and hypercholesterolemia. According to our findings, we cannot detect any relationship. Controlled studies and studies with human individuals can be made possible in the future with diagnostic innovations in tissue imaging and tissue microcircular sampling.

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

: 15 children aged between two and 36 months and with diagnosis of sensorineural hearing loss. The correlation between the responses of the two tests was evaluated by intraclass correlation coefficient and McNemar test comparing the probability of responses in both tests. RESULTS: The correlation coefficients were: 0.70; 0.64; 0.49; 0.69; 0.63 and 0.68 respectively for frequencies of 1, 2, 4, 1-2, 2-4 and 1-2-4kHz. In McNemar test p = 0.000, indicating that the probability of obtaining responses in both tests was not equal, but greater for the ASSR. CONCLUSION: we found good agreement between the techniques among the four frequencies evaluated, suggesting that both tests may be complementary. However, the ASSR was able to obtain additional information in cases of severe and profound hearing losses, adding important data to the management of these children, providing greater accuracy to the audiological diagnosis.

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.

Individual Hearing Loss

Full Text Available It is well-established that hearing loss does not only lead to a reduction of hearing sensitivity. Large individual differences are typically observed among listeners with hearing impairment in a wide range of suprathreshold auditory measures. In many cases, audiometric thresholds cannot fully account for such individual differences, which make it challenging to find adequate compensation strategies in hearing devices. How to characterize, model, and compensate for individual hearing loss were the main topics of the fifth International Symposium on Auditory and Audiological Research (ISAAR, held in Nyborg, Denmark, in August 2015. The following collection of papers results from some of the work that was presented and discussed at the symposium.

Vibrant Soundbridge rehabilitation of conductive and mixed hearing loss.

Science.gov (United States)

Lüers, Jan-Christoffer; Hüttenbrink, Karl-Bernd

2014-12-01

The Vibrant Soundbridge is the world's most often implanted active middle ear implant or hearing aid. During the last few years, the device indications have expanded from sensorineural hearing loss to conductive and mixed hearing loss. Titanium couplers have led to improved contact of the floating mass transducer with the middle ear structures. The resulting hearing gain is satisfying for most patients, but so far, there is no clear audiologic advantage over conventional hearing aids. Currently, the indications are mainly related to intolerance of conventional hearing aids (eg, chronic otitis externa), severe mixed hearing loss with a destructed middle ear and certain medical diagnosis (eg, congenital atresia).

Otoacoustic emissions are signals that originate from the cochlea, measuring them can be considered an objective method in the assessment of auditory function. In our study we wanted to examine their efficiency among normal audiological exams. We examined 14 workers exposed to continuous aircraft noise. They underwent ENT examination, metric eardrum test, hearing test tone audiometry system powered by 1 dB, spontaneous otoacoustic emissions and evoked otoacoustic emissions. For inclusion in the study the patients had to show bilateral normoacusia at the audiometry. The variation of the audiometric tracks was statistically significant (p workers and provides objective results, so it is a more effective and objective method then the tone audiometry.

Using Linden's functional scheme as a theoretical reference framework, we define a matrix of component for clinical and field applications in the acoustic diagnostic process and correlations with audiologic, learning and behavioral problems. It is expected that the model effectively contributes to classify and provide a greater knowledge about this multidisciplinary problem. Although the exact nature of this component is at present a matter to be defined, its correlation can be hypothetically established. Applying this descriptive and integral approach in the diagnostic process it is possible if not to avoid, at least to decrease, the uncertainties and assure the proper solutions becoming a powerful tool applicable to environmental studies and/or social claims.

Contextually-relevant resources in Speech-language Therapy and Audiology in South Africa: Are there any?

Directory of Open Access Journals (Sweden)

Michelle Pascoe

2011-11-01

Full Text Available In this editorial introduction we aim to explore the notion of contextually-relevant resources. We argue that it is the responsibility of Speech Language Therapists (SLTs and Audiologists (As working in South Africa to develop contextually relevant resources, and not to rely on the countries or cultures where the professions originated to do so. Language is often cited as the main barrier to contextually relevant resources: most SLTs and As are aware of the need for more resources in the indigenous local languages. However, the issue is not as straightforward as translating resources from English into other languages. The challenges related to culture, e.g. formal education, familiarity with the test situation, have to be considered; as well as the population on which norms were obtained; the nature of vocabulary or picture items. This paper introduces four original research papers that follow in this edition of the journal, and showcases them as examples of innovative development in our field. At the same time we call for the further development of assessment materials, intervention resources, and contributions to the evidence base in our context. We emphasise the importance of local knowledge to drive the development of these resources in innovative and perhaps unexpected ways, and suggest that all clinicians have an important role to play in this process.

Introduction  Diode laser is a new alternative in stapes surgery for otosclerosis. The present study is the first to compare the short-term results of the surgery performed using diode laser to those obtained through the conventional fenestration technique. Objective  To use audiometry to establish a comparative analysis between the functional results obtained through surgery for otosclerosis using diode laser and the conventional technique. Method  Audiometric evaluation of 12 patients submitted to stapes surgery for otosclerosis, using diode laser or conventional fenestration by needle and drills, between 2014 and 2015. Each group was composed of 6 patients. Pre and post-operative measures were compared for three months in both groups. The speech recognition threshold, the air and bone conduction threshold, as well as the gap between them at 500 Hz, 1 KHz, 2 KHz and 4 KHz were measured. Results  Significant difference in bone conduction and SRT was observed when compared post- and preoperative results in the diode group. However diode and conventional technique groups presented significant differences in air conduction and air-bone gap, suggesting that both can provide functional improvement. Conclusion  Laser stapedotomy is a safe technique with good results. Both laser surgery and the conventional technique have improved the hearing of patients with a discreet advantage for the diode laser. Further prospective and randomized clinical trials are required to disclose all possible benefits of the stapes surgery using diode laser.

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 past, no definitive diagnostic study was available to assess causes of sudden-onset hearing loss and vertigo. Our observations have led to an interesting new finding: labyrinthine enhancement on Gd-enhanced MR imaging in four patients with sudden unilateral hearing loss and/or vertigo. MR findings were correlated with audiologic and vestibular studies. All patients were studied with T2-weighted axial images through the whole brain and with Gd-DTPA-enhanced, 3-mm, axial, T1-weighted images through the temporal bone. No labyrinthine enhancement was seen in 20 control patients referred for other clinical problems. Gd-MR imaging might be able to distinguish patients with retrocochlear lesions from those in whom the abnormal process is in the labyrinth or is intraaxial

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.

To delineate the auditory functional improvement and peri-operative outcomes of the Sophono™ transcutaneous bone conduction device. Eligible articles presenting patients implanted with the Sophono™ were identified through a comprehensive search of PubMed and Embase electronic databases. All relevant articles were reviewed to justify inclusion independently by 2 authors. Studies that successfully passed critical appraisal for directness of evidence and risk of bias were included. From a total of 125 articles, 8 studies encompassing 86 patients using 99 implants were selected. Most patients (79.1%) were children. Ear atresia (67.5%) was the most frequently reported indication for Sophono™ implantation. Overall pure tone average auditory improvement was 31.10 (±8.29) decibel. During a mean follow-up time of 12.48 months, 25 patients (29%) presented with post-operative complications from which 3 were deemed as serious implant-related adverse events (3.5%). The Sophono™ transcutaneous bone conduction device shows promising functional improvement, no intra-operative complications and minor post-operative skin related complications. If suitable, the device could be a proposed solution for the rehabilitation of hearing in children meeting eligibility criteria. A wearing schedule must be implemented in order to reduce magnet-related skin complications. Copyright © 2017 Elsevier B.V. All rights reserved.

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

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.

Full Text Available Magdalena Lachowska, Agnieszka Pastuszka, Paulina Glinka, Kazimierz Niemczyk Department of Otolaryngology, Hearing Implant Center, Medical University of Warsaw, Warsaw, Poland Purpose: To assess the benefits of cochlear implantation in the elderly. Patients and methods: A retrospective analysis of 31 postlingually deafened elderly (≥60 years of age with unilateral cochlear implants was conducted. Audiological testing included preoperative and postoperative pure-tone audiometry and a monosyllabic word recognition test presented from recorded material in free field. Speech perception tests included Ling's six sound test (sound detection, discrimination, and identification, syllable discrimination, and monosyllabic and multisyllabic word recognition (open set without lip-reading. Everyday life benefits from cochlear implantation were also evaluated. Results: The mean age at the time of cochlear implantation was 72.4 years old. The mean post-implantation follow-up time was 2.34 years. All patients significantly improved their audiological and speech understanding performances. The preoperative mean pure-tone average threshold for 500 Hz, 1,000 Hz, 2,000 Hz, and 4,000 Hz was 110.17 dB HL. Before cochlear implantation, all patients scored 0% on the monosyllabic word recognition test in free field at 70 dB SPL intensity level. The postoperative pure-tone average was 37.14 dB HL (the best mean threshold was 17.50 dB HL, the worst was 58.75 dB HL. After the surgery, mean monosyllabic word recognition reached 47.25%. Speech perception tests showed statistically significant improvement in speech recognition. Conclusion: The results of this study showed that cochlear implantation is indeed a successful treatment for improving speech recognition and offers a great help in everyday life to deafened elderly patients. Therefore, they can be good candidates for cochlear implantation and their age alone should not be a relevant or excluding factor when choosing

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

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. 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. 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

Treatment options for subjective tinnitus: Self reports from a sample of general practitioners and ENT physicians within Europe and the USA

Full Text Available Abstract Background Tinnitus affects about 10-15% of the general population and risks for developing tinnitus are rising through increased exposure to leisure noise through listening to personal music players at high volume. The disorder has a considerable heterogeneity and so no single mechanism is likely to explain the presence of tinnitus in all those affected. As such there is no standardized management pathway nor singly effective treatment for the condition. Choice of clinical intervention is a multi-factorial decision based on many factors, including assessment of patient needs and the healthcare context. The present research surveyed clinicians working in six Westernized countries with the aims: a to establish the range of referral pathways, b to evaluate the typical treatment options for categories of subjective tinnitus defined as acute or chronic, and c to seek clinical opinion about levels of satisfaction with current standards of practice. Methods A structured online questionnaire was conducted with 712 physicians who reported seeing at least one tinnitus patients in the previous three months. They were 370 general practitioners (GPs and 365 ear-nose-throat specialists (ENTs from the US, Germany, UK, France, Italy and Spain. Results Our international comparison of health systems for tinnitus revealed that although the characteristics of tinnitus appeared broadly similar across countries, the patient's experience of clinical services differed widely. GPs and ENTs were always involved in referral and management to some degree, but multi-disciplinary teams engaged either neurology (Germany, Italy and Spain or audiology (UK and US professionals. For acute subjective tinnitus, pharmacological prescriptions were common, while audiological and psychological approaches were more typical for chronic subjective tinnitus; with several specific treatment options being highly country specific. All therapy options were associated with low levels

Full Text Available Along with the inspection of acoustical cortex and brainstem EP in neurologic, otoneurologic and audiologic practice recently start to use so-called vestibular evoked myogenic potentials (VEMP. It is shown, that at ear stimulation by a loud sound and record of sterno-cleidomastoid contraction is possible to estimate function of the inferior vestibular nerve and vestibulospinal pathways, a sacculo-cervical reflex. In article some methodical and clinical questions of application of these kinds are presented. Combine research acoustic brainstem EP and VEMP allows to confirm effectively lesions of acoustical and vestibular ways at brainstem. The conclusion becomes, that this kind of inspection is important for revealing demielinisation and defeats in vestibulospinal tract, that quite often happens at MS, and at estimation of efficiency of treatment

Pankova, V B; Preobrazhenskaya, E A; Fedina, I N

The objective of the present study was to analyze the structure of concomitant somatic pathology in the subjects experiencing the occupational hearing problems. The study demonstrated the increase in the frequency of concomitant chronic diseases and the prevalence of polynosological conditions with the increasing severity of hearing impairment. It was shown that cardiovascular pathologies tend to enhance the risk of hearing loss in the employees engaged in «noisy» occupations. The cause-and-effect relationships were elucidated as the contribution of the "vascular" factor to the formation of occupational pathology of the organs of hearing. The clinical audilogical features of co-morbid occupational hearing impairment associated with vascular pathology were characterized by the accelerated development and progression of the hearing disorders with the gradual disappearance of the audiological signs characteristic of noise-induced lesions.

The purpose of this study was to analyse the Questionnaire on Hypersensitivity to Sound (GUF; Nelting & Finlayson, 2004 ) and to improve its validity based on the analysis of intercorrelations (single item level) with other methods of assessing hyperacusis (uncomfortable loudness level, individual loudness function, self-rated severity of hyperacusis). Subjects consisted of 91 inpatients with tinnitus and hyperacusis. The GUF showed a good reliability (alpha = .92). The factorial structure of the questionnaire reported by Nelting et al (2002) was not completely supported by the evidence in this study. The total score and the single items showed small to moderate correlations with the other modes of measuring hyperacusis. Evidence for convergent and discriminant validity were found, but overall the results corroborate the conceptual heterogeneity of the construct hyperacusis and its dependency on the assessment method. Four items of the GUF with particularly low correlations were excluded from the questionnaire. The revised GUF total score showed slightly but not statistically significant higher convergent and discriminant validity.

Full Text Available Objectives: Hearing loss is a major public health problem and has higher prevalence in elderly persons. Present study was conducted with the aim of characterizing age-related changes on audiometric thresholds and word discrimination ability of people with age range of 30 to 100 years. Methods & Materials: Hundred ninty persons (male 53.68% and female 46.32% in seven aged decades were studied from May 2005 to Oct 2007 in Tehran. Individuals who referred for auditory evaluation had concern regarding presence of a kind of hearing problem. Pure tone audiometry, word discrimination score and immittance audiometry were performed for those people who has no previous history of auditory impairment and/or experiencing hearing hazardous agents. Results: There was a significant reverse correlation between recording of acoustic reflexes with both age and hearing loss average. Loss of hearing sensitivity among seven aged decades was significant statistically. Hearing loss showed more decrement in men than women in all audiometric frequencies, and the difference between them was significant in higher frequencies. Decrease of word discrimination score with age growth was significant, and with 12.63% permanent tinnitus, 6.84% vertigo/dizziness and 4.21% history of hearing aid usage were reported in all individuals. Conclusion: Hearing sensitivity declines gradually and progressively with aging. Effects of hearing loss and some of it's associated disorders specially tinnitus and vertigo/ dizziness on degree of communication and quality of life in such individuals and higher prevalence in aged people reveals the necessity of scientific and executive programming for identification and treatment of auditory problems in such population.

The latest scientific literature considers early diagnosis of deafness as the key element to define the educational and inclusive prognosis of the deaf child, because it allows taking advantage of the critical period of development (0-4 years). Highly significant differences exist between deaf people who have been stimulated early and those who have received late or improper intervention. Early identification of late-onset disorders requires special attention and knowledge on the part of every childcare professional. Programs and additional actions beyond neonatal screening should be designed and planed to ensure that every child with a significant hearing loss is detected early. For this purpose, the CODEPEH would like to highlight the need for continuous monitoring of children's auditory health. Consequently, CODEPEH has drafted the recommendations included in the present document.

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.

The aim of the study was to investigate whether children with bilateral conductive hearing loss benefit from their second device (i.e., the bilateral bone conduction device [BCD]). Speech recognition in noise was assessed in 10 children fitted with bilateral BCDs during childhood. Speech recognition was measured in 2 conditions with both BCDs active. Spatial resolution was tested with the Minimum Audible Angle test in the bilateral and monaural listening conditions. Children demonstrated an improvement in speech recognition when speech was presented from the front and noise was presented from the right-hand side as compared with both speech and noise being presented from the front. The minimum audible angle decreased from 57° in the best monaural condition to 13° in the bilateral condition. The audiological outcomes demonstrate the advantage of bilateral BCD fitting in children with bilateral conductive hearing loss.

Especially in the elderly, hearing loss can impair the exchange of information, thus significantly impacting everyday life, causing loneliness, isolation, dependence, and frustration, as well as communication disorders. Due to the aging of the population in the developed world, presbycusis is a growing problem that has been reported to reduce quality of life (QoL. Progression of presbycusis cannot be remediated; therefore, optimal management of this condition not only requires early recognition and rehabilitation, but it also should include an evaluation of QoL status and its assessment.Keywords: hearing loss, presbycusis, quality of life, elderly

Full Text Available We describe a 57 year old, right handed, English speaking man initially diagnosed with progressive aphasia. Language assessment revealed inconsistent performance in key areas. Expressive language was reduced to a few short, perseverative phrases. Speech was severely apraxic. Primary modes of communication included gesture, pointing, gaze, physical touch and leading. Responses were 100% accurate when he was provided with written words, with random or inaccurate responses for strictly auditory/verbal input. When instructions to subsequent neuropsychological tests were written instead of spoken, performance improved markedly. A comprehensive audiology assessment revealed no hearing impairment. Neuroimaging was unremarkable. Neurobehavioral evaluation utilizing written input led to diagnoses of word deafness and frontotemporal dementia, resulting in very different management. We highlight the need for alternative modes of language input for assessment and treatment of patients with language comprehension symptoms.

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.

Acute otitis media is very general disease and concerns every child practically. The shortening the time of treatment as well as quick decrease of symptoms, and mainly the pain have large meaning in treatment of this disease. Combined treatment of fenspiride and typical treatment of otitis media permits as our investigations show on quicker and observed at children's larger number decrease of symptoms in children with acute otitis media. The aim of the study was to observe effectiveness of combined treatment with antibiotic and fenspiride in children with acute otitis media. The study comprised 40 children (mean age 8.2 years). The diagnosis of acute otitis media based on medical history data, otolaryngological examination and audiometry (tone and impedance). Children with GERD, hypersensitivity to amoxicillin and fenspiride as well as hypertrophy of adenoid were excluded from the study. Children were divided in two equal groups randomly. All children received amoxicillin in dose 80 mg/kg/day in three partite doses (Amotaks, Polfa Tarchomin Poland) as well as oxymethazolin 0.05% nasal drops 3 x day 1-2 drops (0.05% Nasivin, Merck Germany). In children from second group fenspiride was applied in dose 2 ml/kg/day in three divided doses (Eurespal, Servier Francja) additionally. Treatment was provided by 10 days. During the treatment parents made record of recession in 10 point scale, estimating following parameters: the pain of ear, bother, raised the temperature of body, loss of appetite, vomiting, diarrhea, otorrhea and crying.

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

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

This work was designed to study electroencephalogram findings in children with congenital sensorineural hearing loss and correlate these findings with the SNHL parameters as duration, etiology, severity, and type. Ninety children with bilateral congenital sensorineural hearing loss served as the study group. They were free from any neurological disorders or symptoms that are commonly associated with abnormal electroencephalogram as convulsions or loss of consciousness. Twenty children having normal hearing with no history of otological or neurological disorders served as the control group. All children participating in the study were subjected to full medical and audiological history, otological examination, neurological examination, audiological evaluation and electroencephalogram recording. Mean age of the children in the control group was 3.56 ± 2.1 years and mean age of the children in the study group was 3.8 ± 2.2 years. While none of the control children had abnormal electroencephalogram, 38 (42.2%) of children with congenital SNHL had epileptiform electroencephalogram abnormality. The epileptiform abnormality was generalized in 14 children (36.8%), focal temporal in 17 children (44.7%) and focal other than temporal in 7 children (18.4%). According to the hemispheric side affected, the abnormality was right in 14 children (36.8%), left in 10 children (26.3%) and bilateral in 14 children (36.8%). No statistically significant predominance of specific site or side of the epileptiform abnormality was found. Similarly, no statistical significant prevalent of the epileptiform abnormality was found in relation to the age or sex of children, duration of hearing loss or etiology of hearing loss (i.e., genetic vs. neonatal insults). On the other hand, the epileptiform abnormality was statistically prevalent in children with moderate degree of hearing loss, and in children with auditory neuropathy spectrum disorder.

More than 80% of permanent hearing losses (HL) in children are congenital. Newborn hearing screening (NHS) is the best method for early detection of suspected hearing loss. If the NHS is not universal more than 30% permanent hearing losses are not identified. There are various methods of NHS: otoacoustic emissions (TEOAE, DPOAE) and automatic auditory brainstem response (AABR). After hearing screening, and when hearing loss is suspected, tympanometry and audiological methods then used for determination of hearing threshold; these include ABR, ASSR or/and behavioral methods. The goal of this study is to evaluate the influence of UNHS on the early detection of hearing loss in children before and after the implementation of obligatory universal newborn hearing screening in Slovakia, and also on the etiologic evaluation of hearing impaired infants identified by screening. In Slovakia NHS started in 1998 and was provided in ENT departments. From May 1, 2006 UNHS has been mandatory in Slovakia, using two stages TEOAE in all newborn departments in Slovakia (64 newborn departments). In year 2005--42% of newborns in Slovakia were screened, in 2006--66% newborns and in 2007--94, 99% (three small newborn departments do not yet have equipment for OAE screening). For determination of hearing thresholds ASSR are used in two ENT departments and ABR in the other four ENT departments. Comparing the number of identified cases with bilateral severe permanent HL or deafness before and after UNHS, 22.8% more cases of PHL were identified in the first year of UNHS. Also the average age of diagnosis of PHL was lower. In the year 2007, 94% of newborns were screened. We found 0.947/1000 newborns with bilateral severe PHL (35.9%) more than before UNHS). After audiologic and etiologic assessment of the 76 infants who failed screening, 5 (6.58%) were found to have normal hearing, 16 (22.54%) had unilateral and 55 (77.46%) had bilateral SNHL. A non-syndromic genetic cause was present in 25

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

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

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

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

Psychological distress and psychiatric symptoms are prevalent among people with hearing loss or other audiological conditions, but psychological interventions for these groups are rare. This article describes the study protocol for a randomized controlled trial for evaluating the effect of a psychological treatment delivered over the Internet for individuals with hearing problems and concurrent psychological distress. Participants who are significantly distressed will be randomized to either an 8-week Internet-delivered acceptance-based cognitive behavioral therapy (i.e., acceptance and commitment therapy [ACT]), or wa it-list control. We aim to include measures of distress associated with hearing difficulties, anxiety, and depression. In addition, we aim to measure acceptance associated with hearing difficulties as well as quality of life. The results of the trial may further our understanding of how to best treat people who present problems with both psychological distress and hearing in using the Internet.

OBJECTIVE: It has been suggested that individuals have an inherent acceptance of noise in the presence of speech, and that different acceptance of noise results in different hearing-aid (HA) use. The acceptable noise level (ANL) has been proposed for measurement of this property. It has been...... claimed that the ANL magnitude can predict hearing-aid use patterns. Many papers have been published reporting on different aspects of ANL, but none have challenged the predictive power of ANL. The purpose of this study was to discuss whether ANL can predict HA use and how more reliable ANL results can...... reviewed journals as well as a number of papers from trade journals, posters and oral presentations from audiology conventions. CONCLUSIONS: An inherent acceptance of noise in the presence of speech may exist, but no method for precise measurement of ANL is available. The ANL model for prediction of HA use...

Steven, R A; Kinshuck, A J; McCormick, M S; Ranganath, L R

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.

Inclusive education and personal development.

Leigh, I

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.

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.

Develop and validate an automated smartphone word recognition test. Cross-sectional case-control diagnostic test comparison. An automated word recognition test was developed as an app for a smartphone with earphones. English-speaking adults with recent audiograms and various levels of hearing loss were recruited from an audiology clinic and were administered the smartphone word recognition test. Word recognition scores determined by the smartphone app and the gold standard speech audiometry test performed by an audiologist were compared. Test scores for 37 ears were analyzed. Word recognition scores determined by the smartphone app and audiologist testing were in agreement, with 86% of the data points within a clinically acceptable margin of error and a linear correlation value between test scores of 0.89. The WordRec automated smartphone app accurately determines word recognition scores. 3b. Laryngoscope, 128:707-712, 2018. © 2017 The American Laryngological, Rhinological and Otological Society, Inc.

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.

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.

Decker, Kalli B; Vallotton, Claire D; Johnson, Harold A

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.

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.

Development of the Word Auditory Recognition and Recall Measure: A Working Memory Test for Use in Rehabilitative Audiology.

Smith, Sherri L; Pichora-Fuller, M Kathleen; Alexander, Genevieve

The purpose of this study was to develop the Word Auditory Recognition and Recall Measure (WARRM) and to conduct the inaugural evaluation of the performance of younger adults with normal hearing, older adults with normal to near-normal hearing, and older adults with pure-tone hearing loss on the WARRM. The WARRM is a new test designed for concurrently assessing word recognition and auditory working memory performance in adults who may have pure-tone hearing loss. The test consists of 100 monosyllabic words based on widely used speech-recognition test materials. The 100 words are presented in recall set sizes of 2, 3, 4, 5, and 6 items, with 5 trials in each set size. The WARRM yields a word-recognition score and a recall score. The WARRM was administered to all participants in three listener groups under two processing conditions in a mixed model (between-subjects, repeated measures) design. The between-subjects factor was group, with 48 younger listeners with normal audiometric thresholds (younger listeners with normal hearing [YNH]), 48 older listeners with normal thresholds through 3000 Hz (older listeners with normal hearing [ONH]), and 48 older listeners with sensorineural hearing loss (older listeners with hearing loss [OHL]). The within-subjects factor was WARRM processing condition (no additional task or with an alphabet judgment task). The associations between results on the WARRM test and results on a battery of other auditory and memory measures were examined. Word-recognition performance on the WARRM was not affected by processing condition or set size and was near ceiling for the YNH and ONH listeners (99 and 98%, respectively) with both groups performing significantly better than the OHL listeners (83%). The recall results were significantly better for the YNH, ONH, and OHL groups with no processing (93, 84, and 75%, respectively) than with the alphabet processing (86, 77, and 70%). In both processing conditions, recall was best for YNH, followed by ONH, and worst for OHL listeners. WARRM recall scores were significantly correlated with other memory measures. In addition, WARRM recall scores were correlated with results on the Words-In-Noise (WIN) test for the OHL listeners in the no processing condition and for ONH listeners in the alphabet processing condition. Differences in the WIN and recall scores of these groups are consistent with the interpretation that the OHL listeners found listening to be sufficiently demanding to affect recall even in the no processing condition, whereas the ONH group listeners did not find it so demanding until the additional alphabet processing task was added. These findings demonstrate the feasibility of incorporating an auditory memory test into a word-recognition test to obtain measures of both word recognition and working memory simultaneously. The correlation of WARRM recall with scores from other memory measures is evidence of construct validity. The observation of correlations between the WIN thresholds with each of the older groups and recall scores in certain processing conditions suggests that recall depends on listeners' word-recognition abilities in noise in combination with the processing demands of the task. The recall score provides additional information beyond the pure-tone audiogram and word-recognition scores that may help rehabilitative audiologists assess the listening abilities of patients with hearing loss.

Self-Reported Usage, Functional Benefit, and Audiologic Characteristics of Cochlear Implant Patients Who Use a Contralateral Hearing Aid

Full Text Available Ninety-four unilateral CI patients with bimodal listening experience (CI plus HA in contralateral ear completed a questionnaire that focused on attitudes toward hearing aid use postimplantation, patterns of usage, and perceived bimodal benefits in daily life. Eighty participants continued HA use and 14 discontinued HA use at the time of the questionnaire. Participant responses provided useful information for counseling patients both before and after implantation. The majority of continuing bimodal (CI plus HA participants reported adapting to using both devices within 3 months and also reported that they heard better bimodally in quiet, noisy, and reverberant conditions. They also perceived benefits including improved sound quality, better music enjoyment, and sometimes a perceived sense of acoustic balance. Those who discontinued HA use found either that using the HA did not provide additional benefit over the CI alone or that using the HA degraded the signal from the CI. Because there was considerable overlap in the audiograms and in speech recognition performance in the unimplanted ear between the two groups, we recommend that unilateral CI recipients are counseled to continue to use the HA in the contralateral ear postimplantation in order to determine whether or not they receive functional or perceived benefit from using both devices together.

Work-related noise exposure is one of the major factors contributing to the development of adult-onset hearing loss and tinnitus. The aim of this study was to analyze, in patients with chronic tinnitus and long-term occupational noise exposure, (A) characteristics of hearing loss, tinnitus, comorbidities, demographic characteristics and a history of work-related noise exposure and (B) differences among individuals employed in occupations with high and low risk of developing work-related noise-induced hearing loss (NIHL). One hundred thirty six patients with chronic tinnitus and at least a 10 year-long working history were divided into two groups based on the risk of their profession to induce NIHL. Individuals employed in jobs at high risk for NIHL were mostly males and exhibited a poorer hearing threshold, more evident in the left ear. Tinnitus was mostly bilateral; the next largest presentation was left-sided; patients described their tinnitus as buzzing or high-pitched. Correlation between age, length of tinnitus and worse hearing was found. Patients with a higher degree of hearing impairment were mostly males and were more likely to have a family history of hearing loss and at least one cardiovascular comorbidity. Our study shows some differences in individuals with tinnitus and a history of a profession associated with increased exposure to NIHL compared to those without such a history.

Recruiting into clinical trials on time and on target is a major challenge and yet often goes unreported. This study evaluated the adjustment to procedures, recruitment and screening methods in two multi-centre pharmaceutical randomised controlled trials (RCTs) for hearing-related problems in adults. Recruitment monitoring and subsequent adjustment of various study procedures (e.g. eligibility criteria, increasing recruiting sites and recruitment methods) are reported. Participants were recruited through eight overarching methods: trial registration, posters/flyers, print publications, Internet, social media, radio, databases and referrals. The efficiency of the recruitment was measured by determining the number of people: (1) eligible for screening as a percentage of those who underwent telephone pre-screening and (2) randomised as a percentage of those screened. A total of 584 participants completed the pre-screening steps, 491 screened and 169 participants were randomised. Both RCTs completed adjustments to the participant eligibility, added new study sites and additional recruitment methods. No single recruitment method was efficient enough to serve as the only route to enrolment. A diverse portfolio of methods, continuous monitoring, mitigation strategy and adequate resourcing were essential for achieving our recruitment goals.

Full Text Available Statement of Problem. Stapedotomy is the treatment of choice for otosclerosis. Numerous techniques and prosthesis are available to perform this procedure. Success rates of surgery vary from 17% to 80%, and revision surgery carries an increased risk of complications as well as poorer hearing outcomes. Method of Study. Case report. Results. We report the first case of uncrimping of a SMart stapes prosthesis with no lateral displacement as a cause of late failure despite successful crimping and improvement in audiological outcomes after initial surgery. Conclusion. The SMart stapes prosthesis is widely used and has been shown to be safe and provide good hearing outcomes. Displacement of a stapes prosthesis is the commonest cause of failure. Our case shows that deterioration of hearing thresholds can occur from uncrimping of the prosthesis with no displacement. It is important to improve our understanding of stapedotomy failure as revision procedures are associated with poorer outcomes.

Acoustic startle reflex and pre-pulse inhibition in tinnitus patients

2014-01-01

Gap induced pre-pulse inhibition (Gap-PPI) of acoustic startle reflex has been used as a measurement of tinnitus in animal models. However, whether this test is sensitive to detect tinnitus in humans is still unclear. Based on the testing procedure used in animal studies, a human subject testing method was formulated and conducted to investigate if a similar result could be found in tinnitus patients. Audiologic and tinnitus assessments and acoustic startle reflex measurements were performed on seven tinnitus subjects and nine age matched subjects without tinnitus. There was no significant difference found between the control and tinnitus group on the Gap-PPI across the frequencies evaluated. The amplitude of the startle response in the tinnitus group with normal hearing thresholds was significantly higher than the control group and those with tinnitus and hearing loss. This preliminary result suggests that hyperexcitability in the central auditory system may be involved in tinnitus. There was no correlation between hearing thresholds and the increased amplitude of startle response.

Congenital Permanent Childhood Hearing Impairment (PCHI) is known to have a negative effect on language acquisition, cognitive development and social integration. Since 2000 our department has implemented a UNHS program in the West of Ireland. We describe our experience and detail our results to date. All neonates born from October 2000 to November 2007 were screened using a 2-stage protocol. Transient evoked oto-acoustic emissions (TEOAEs) were used to screen all neonates, followed by automated auditory brainstem response (AABR) in those who did not pass TEOAE, and all neonates at audiological risk. 26,281 babies were born over the eight year period. 25,742 underwent the screening process, achieving a coverage rate of 98%. The prevalence of PCHI in the population tested was 1.21\\/1000 live births (31\\/25,731). Our results show that a hospital based 2-stage UNHS protocol using TEOAEs and AABR is accurate, feasible and effective.

Letter to the Editor: License Portability for Occupational Audiologists is Essential

Full Text Available Occupational audiologists have a crisis in their profession and need advocates. These audiologists are primarily responsible for industrial hearing conservation programs and their compliance with multiple regulations, such as Occupational Safety and Health Administration (OSHA, Mine Safety and Health Administration (MSHA and the Federal Railroad Administration.  Occupational hearing programs, for the most part, are multi-state programs as companies and corporations are national organizations. Also, companies may contract services across state lines as local services may not be desired or available. Individual state telepractice regulations require audiologists who are professionally supervising these programs via the internet and phone, to secure licensure in each state. For this licensure redundancy, the cost in time and tracking are enormous.  It is imperative that the American Speech-Language-Hearing Association (ASHA, secure multistate licensure for speech-language pathologists and audiologists. For the profession of occupational audiology, it is essential. Keywords: Licensure, Occupational audiologists, Telehealth, Telepractice

To assess the auditory and vestibular function in patients with diabetes. We studied and followed for three years, 10 patients (6 females) of 20.6 years of age (SD 5.5 years), with insulindependent diabetes mellitus of 9.5 years (SD 3.7 years). The patients were selected for having peripheral neuropathy without prolipherative retinopathy and otologic disease or individual factors which could cause neurootologic symptoms. Their glomerular filtration rate and renal plasma flow were 150 mL/min (SD 50) and 543 mL/min (SD 113). Initially all patients had normal audiologic responses, including auditory brainstem responses, but had abnormally and simetrically diminished horizontal vestibulo-ocular responses. A year later one patient had vertigo and asymmetric vestibulo-ocular responses. In the third year, another patient showed similar abnormalities and a third one showed sensorineural hearing loss. Our results suggest that patients with insulindependent diabetes mellitus may suffer neuro-otological deterioration.
