    In the Netherlands audiological care is given at different stages. An attempt is made to screen the hearing of all Dutch babies between the ages of 8 and 12 months. At the age of 4 or over, general audiological care is given by the school medical service; referral is first to a family doctor, who may refer to an otolaryngologist. Curative medical care (examination and therapy) is the province of the family doctor and the otolaryngologist. Otolaryngologists and pediatricians can refer patients to one of 19 Audiological Centers distributed around the country, where a number of workers in different disciplines cooperate for habilitation and rehabilitation. These may include an otolaryngologist in charge, a psychologist, a speech and hearing therapist, an audiologist (usually a physicist or university-trained engineer), social worker, technician, ortho-pedagogue, audiology assistant, and teacher. There are at the moment 25 schools for the hard of hearing and 5 institutes for the deaf. These are often found in conjunction with Audiological Centers, the latter providing paramedical assistance to the pupils by agreement. Finally, the Dutch Organization for Preventive Medicine works to prevent hearing loss in noisy industries.

    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.

    Full Text Available Introduction Vestibular schwannoma (acoustic neuroma is a rare, but important cause of sensorineural hearing loss. Patients with asymmetric hearing loss, or unilateral tinnitus should be evaluated expeditiously, to prevent further neurological damage. Audiologic diagnostics Audiologic diagnostics represents the basic diagnosis for early detection of vestibular schwannoma. Patients with vestibular schwannomas may present with a variety of clinical features, including retrocochlear pattern of sensorineural hearing loss. Supraliminary audiometry, tympano- metry, stapedius reflex and otoacoustic emissions as well as vestibular response to caloric testing are methods for selection of patients with suspicion of this tumor. Conclusion The golden standard for audiologic diagnostics of vestibular schwannoma is BAEP (Brainstem Auditory Evoked Potentials. Patients with pathological findings of BAEP should undergo MRI of the posterior fossa. Gadolinium-enhanced magnetic resonance imaging is the best and final tool for making a diagnosis of vestibular schwannoma.

    The present report provides an overview of terminology studies in audiology including topics and study characteristics, as well as categorizing the main issues. The goals are to improve the understanding of the current issues for terminology in audiology and to provide some basic information that will be useful to develop an international standard. Search procedures were completed over two phases. Phase 1 included a systematic electronic searches using MEDLINE (PubMed), Excerpta Medica Database, Cumulative Index to Nursing and Allied Health Literature, and International Organization for Standardization with keywords related to terminology of audiology. The studies were initially identified according to the titles of 2921 publications following careful abstract examination. Of these, whole texts of 16 publications were retrieved. Five papers met the inclusion criteria were further investigated. In phase 2, a manual search was conducted to collect additional publications with keywords related to terminology project in audiology. A total of 16 papers were found. The essential terminology issues classified included 'appropriateness,' 'classification/framework,' 'inconsistency of terminology,' 'multilingual and international aspects,' and 'service quality/delivery including communication and accessibility.' This was indicative of the paucity of terminology research in audiology, despite recurring terminology issues. Establishment of standardized terminology in audiology may minimize current challenging terminology issues by improving appropriateness and consistency of terminology as well as communication among relevant stakeholders at national and international levels.

    Audiological manifestations in a four-year-old child with Infantile Refsum disease are reported. He was born to non-consanguineous parents and had normal birth history and mildly delayed milestones prior to presentation. Clinical features were characterized by neuroregression, retinitis pigmentosa, hearing loss, peripheral neuropathy and white matter signal changes on magnetic resonance imaging. Biochemical evaluation showed elevated serum levels of long chain fatty acid and phytanic acid confirming the diagnosis. The audiological profile was characterized by absent auditory brainstem responses with robust otocoustic emissions, which indicated auditory neuropathy as the possible cause of hearing loss.

    Full Text Available Background: Over the past decades there has been increase demand of audiological complaints coinciding with neurological impairments due to cerebrovascular accidents (CVAs. Most of the cases represent inconsistent responses to acoustic stimuli or total lack of response to sound, documented as auditory agnosia. Aim: The present investigation aims at understanding of potential anatomical co-relates to the involvement of the cortical structure and the processing of auditory stimuli. Materials and Methods: A case series with convenient sampling method included eight cases (six male and two female with age range 45-55 years with CVA, were taken for this study. Of them two cases were found with lesion in right middle cerebral artery, four cases with left middle cerebral artery and two cases with left posterior cerebral artery lesion confirmed from magnetic resonance imaging scan. Audiological test battery including otoscopy, tuning fork test, pure tone audiometry, speech audiometry, immittance audiometry, dichotic-diotic listening test, auditory brainstem responses, otoacoustic emissions and gap detection tests were carried out including routine ENT evaluation. Results and Conclusion: Result suggests; there is a significant difference in hearing threshold and speech perception in all the eight subjects. The findings and compromised vascular anatomy in all these cases were discussed in this article.

    Full Text Available Objectives: The aim of our study is to find out whether early identification and intervention prevents severe linguistic and communication delays, minimizing the need for more elaborate rehabilitation during the school years. Design and Study Sample: A Cross-sectional study was carried out on one hundred and eleven children with documented deaf-mutism presenting at the Department of Oto-Rhino-Laryngology in two different geographical regions of India. Detailed history, clinical and audiological assessment along with assessment of the language and communication skills according to American Speech Language Hearing Association (ASHA guidelines was done. Results: The children were predominantly male, of low socio-economic background, presented for rehabilitation, mostly after the age of six years. They commonly had more than 70dBHL (decibel hearing level hearing threshold. The study found that the children who presented early for diagnosis and hearing aid usage had better response to rehabilitation. Conclusion: It is important that hearing loss be detected at an early age and amplification should be introduced as early as possible once there has been a diagnosis of a hearing loss. So that early intervention can have an impact on speech and language development. Without concurrent follow-up program, identification of hearing loss early in children is meaningless.

    Prabhu, Prashanth; Shivaswamy, Jyothi

    2017-01-01

    Summary Reported here are audiological findings from an adult with thin cochlear nerves. Magnetic resonance imaging (MRI) revealed that he had a thinner cochlear nerve in the left ear than in the right ear. He had a higher degree of hearing loss in the left ear and poor speech recognition scores for both ears. He had normal middle ear and cochlear functioning. The auditory brainstem response and acoustic reflexes were absent, indicating a retrocochlear pathology. Long latency responses (LLR) revealed normal cortical functioning. Hence, implantation of an auditory brainstem implant might be an option, but the patient would need to be aware of its limitations. This case highlights the importance of MRI in evaluating congenital malformations of the cochlear nerve when audiological findings indicate a retrocochlear pathology. PMID:28357188

    Objectives To define the audiologic and otologic phenotype of Hutchinson-Gilford Progeria syndrome (HGPS). Study Design Prospective case series. Methods Fifteen patients with HGPS were enrolled in a prospective natural history study; fourteen were evaluated in the neurotology clinic and eleven received audiologic evaluations. The physical exam and audiologic findings of these patients were reviewed to define an otologic and audiologic phenotype for HGPS in the largest series of subjects in the literature. Results All patients were noted to have stiff auricular cartilages, small or absent lobules and hypoplasia of the lateral soft tissue portion of the external ear canal leading to a shortened canal. Ten of 14 patients (71%) had dry cerumen impaction and four of 14 patients (29%) reported a history of recurrent otitis media. Nineteen of 22 ears (86.4%) demonstrated low frequency conductive hearing loss in the 250 Hz to 500 Hz range. Sixteen of 22 ears (73%) had type A tympanograms; three of 22 ears (14%) displayed bimodal or "W" peaked tympanograms; two of 22 ears (9%) had type B tympanograms; one of 22 ears (4%) had a type C tympanogram. Nine of 10 patients had distortion product otoacoustic emissions consistent with normal peripheral hearing sensitivity. Conclusions HGPS is caused by a mutation in the LMNA gene resulting in the production of an abnormal nuclear protein; this in turn affects nuclear structure and function. Patients with HGPS have characteristic otologic features due to cartilaginous and subcutaneous tissue abnormalities and typically demonstrate low frequency conductive hearing loss despite largely normal tympanometry. It is important to be aware of these conditions in managing these patients. PMID:21898437

    Full Text Available Background: The mucopolysaccharidoses (MPS is an autosomal recessive disorder, caused due to malfunctioning of certain lysosomal enzymes involved in degradation of glycosaminoglycans. This report presents audiological evaluation findings found in two siblings with Morquio syndrome (MPS type IV. Materials and Methods: The present study evaluated two individuals (case A: 18-year-old male and case B: 15-year-old female with a routine audiological evaluation including pure tone audiometry, speech audiometry, and immittance evaluation. Results: Case ′A′ and ′B′ were assessed for three consecutive audiological evaluations over time in a span of 2 years. For case A, all three evaluations revealed same degree of hearing loss in both ears. However, for case B, results reveal that there was increase in degree of hearing loss in both ears. Further, immittance results in both case A and B revealed middle ear pathology in both ears in all the three evaluations. Hence, it can be concluded that there was no progression in severity of hearing loss in case A; however, same was observed in case ′B′. In addition to that, at present both case A and B are using moderate gain digital behind the ear hearing aid in both the ears which is enabling them to communicate better. Conclusion: To conclude on these case reports of the siblings, otologist and audiologist need to be aware of this relevant information and take immediate steps to provide services to patients. Regular follow-up of the clients is an important aspect as it is highlighted in present study.

    2002-01-01

    Audiology has developed significantly over the last 30 years leading to better identification and assessment of hearing loss and better habilitation services for both children and adults with congenital or acquired deafness. Advancement in the profession and its services has been largely dependent on the technological development of key methodologies such as the auditory brainstem response and otoacoustic emissions. These methodologies have been used for the identification and assessment of the severity of hearing loss. As a result, these methodologies have underpinned the emergence of service development initiatives such as hearing screening and provision of hearing aids, particularly for newborn babies and young children. This review identifies, describes and evaluates the key methodologies and services involved and presents a hearing scientist's perspective on the developments to date. The aim is to provide state-of-the-art information to those working with children and adults with communication disorders, particularly speech and language therapists.

    Full Text Available Aim: of the study was to rule out audiologic findings, related etiologies and its effect in pediatric patients having hearing deficits that are most likely due to a neuropathy of the eighth nerve. Study Design: Retrospective neo-natal hearing screening programme based. Subject and Methods: Subjects include 30 children aged from 0 yrs to 12 yrs, were tested with pure tone audiometry, behavioral observation audiometry, free-filed audiometry, speech audiometry, auditory brainstem response, and click evoked otoacoustic emissions. Results: Pure tone and free-field testing revealed 40 ears (66.67%, n = 60 with sloping type, sensorineural hearing loss, 20 ears (33.3%, n = 60 had flat configuration. Out of this 18 (6%, n = 30 subject showed bilateral similar configuration (either bilateral sloping type/ flat type of audiogram. Rest 12 (40%, n = 30 subject showed bilateral different pattern. 10 (33.3%, n = 30 children demonstrated fair to poor word discrimination scores and the other 2 (6.67%, n = 30 had fair to good word discrimination. For other rest of 18 (60%, n = 30 children speech test couldn′t be performed because of age limit and poor speech and language development. Out of 30 subjects 28 (93.3%, n = 30 showed normal distortion product Otoacoustic emissions and 2(6.67%, n = 30 subjects showed absent emissions. Conclusions: All thirty children demonstrated absent or marked abnormalities of brainstem auditory evoked potentials which suggest cochlear outer hair cell function is normal; mostly lesion is located at the eighth nerve or beyond. Generally auditory neuropathy is associated with different etiologies and it is difficult to diagnose auditory neuropathy with single audiological test; sufficient test of battery is required for complete assessment and diagnosis of auditory neuropathy

  4. 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

    2011-12-01

    Full Text Available Abstract Background Osteogenesis Imperfecta (OI is a heritable connective tissue disorder mainly caused by mutations in the genes COL1A1 and COL1A2 and is associated with hearing loss in approximately half of the cases. The hearing impairment usually starts between the second and fourth decade of life as a conductive hearing loss, frequently evolving to mixed hearing loss thereafter. A minority of patients develop pure sensorineural hearing loss. The interindividual variability in the audiological characteristics of the hearing loss is unexplained. Methods With the purpose of evaluating inter- and intrafamilial variability, hearing was thorougly examined in 184 OI patients (type I: 154; type III: 4; type IV: 26, aged 3-89 years, with a mutation in either COL1A1 or COL1A2 and originating from 89 different families. Due to the adult onset of hearing loss in OI, correlations between the presence and/or characteristics of the hearing loss and the underlying mutation were investigated in a subsample of 114 OI patients from 64 different families who were older than 40 years of age or had developed hearing loss before the age of 40. Results Hearing loss was diagnosed in 48.4% of the total sample of OI ears with increasing prevalence in the older age groups. The predominant type was a mixed hearing loss (27.5%. A minority presented a pure conductive (8.4% or pure sensorineural (12.5% loss. In the subsample of 114 OI subjects, no association was found between the nature of the mutation in COL1A1 or COL1A2 genes and the occurrence, type or severity of hearing loss. Relatives originating from the same family differed in audiological features, which may partially be attributed to their dissimilar age. Conclusions Our study confirms that hearing loss in OI shows a strong intrafamilial variability. Additional modifications in other genes are assumed to be responsible for the expression of hearing loss in OI.

    Full Text Available Daily activities, interpersonal relationship, employment, and general well being; among such skills, communication skills are essential to a successful life for all individuals. Such skills affect education, adequate hearing acuity is of paramount importance and acts as a prerequisite in the overall personality development of an individual. Hearing impairment at any age has serious effects on the day to day life of an individual and he/she feels handicapped socially, emotionally, and scholastically. A child stuck with this malady is a back bencher in the class, excommunicative, and absent-minded. This study was conducted in order to find out various causes of hearing impairment in children and to study role of various audiological and radiological tests in finding the cause of impaired hearing in children. Aims and Objectives: To assess the possible etiological causes of hearing impairment in children. Study role of various audiological tests in finding the cause of impaired hearing in children. Study Design: Prospective study. Materials and Methods: This study was conducted in the Department of ENT and HNS of government medical college Srinagar. A total of 150 children of age range 0-14 years visited our ENT Department with complaints of impaired hearing, but only 70 children who met the inclusion criteria of impaired hearing and defective/delayed speech were selected for this study. Results of initial evaluation by means of comprehensive clinical history and followed by proper thorough systemic physical examination from head to toe was performed. These hearing impaired children were subjected to various subjective and objective tests; pure tone audiometry and behavioral observation audiometry were performed for subjective tests and impedance audiometry, Oto-acoustic emissions (OAE, and brainstem evoked response audiometry (BERA were performed for objective tests. Results: Possible etiological cause on the basis of history were birth anoxia (2

    A detailed audiological study combined with certain haematological investigations which were never previously done was undertaken on Todas, a small vanishing tribe of Nilgiris, South India. Ten per cent of the Todas studied exhibited otosclerosis which, though lower than that of a previous study, is still a very high percentage when compared to the general population. The incidence of chronic suppurative otitis media in Todas is markedly low (1-6 per cent) and 13-3 per cent of Todas had sensorineural hearing loss. Evaluation of hearing thresholds at various frequencies in the different age groups did not show much variation from that of the general population. The incidence of presbyacusis is not found to be low as reported earlier. Blood pressure recordings did not show any age-related increase. The majority of Todas studied belonged to the blood group 'B' (63 per cent) and 16-6 per cent belonged to the 'AB' group, which is distinctly different from the distribution pattern seen in the general Indian population. There was no significant variation in the serum cholesterol level in Todas.

    Introduction Oculo-auriculo-vertebral spectrum, also referred to as Goldenhar syndrome, is a condition characterized by alterations involving the development of the structures of the first and second branchial arches. The abnormalities primarily affect the face, the eyes, the spine, and the ears, and the auricular abnormalities are associated with possible hearing loss. Objective To analyze the audiological findings of patients with oculo-auriculo-vertebral spectrum through liminal pure-tone audiometry and speech audiometry test. Methods Cross-sectional study conducted on 10 patients with oculo-auriculo-vertebral spectrum and clinical findings on at least two of the following areas: orocraniofacial, ocular, auricular, and vertebral. All patients underwent tonal and vocal hearing evaluations. Results Seven patients were male and three were female; all had ear abnormalities, and the right side was the most often affected. Conductive hearing loss was the most common (found in 10 ears), followed by sensorineural hearing loss (in five ears), with mixed hearing loss in only one ear. The impairment of the hearing loss ranged from mild to moderate, with one case of profound loss. Conclusions The results show a higher frequency of conductive hearing loss among individuals with the oculo-auriculo-vertebral spectrum phenotype, especially moderate loss affecting the right side.

    Full Text Available Objective: Tinnitus is widespread amongst clients attending hearing clinics and has been associated with a range of physical and emotional disorders. This study was undertaken with the assumption that tinnitus has a negative impact on psychological well-being as well as on mental concentration of the person. Materials and Methods: Three groups were selected, comprising 10 participants each. Two groups consisted of subjects with tinnitus complaints. The first group had no hearing loss (Tinnitus group (TIG, the second group had mild hearing loss (PTA >25, <40 dBHL (Tinnitus group with hearing impairment (TWHIG, and the third group had no tinnitus or hearing loss (Normal control group (NCG. After an audiological assessment, the following questionnaires were administered: 1 nature of tinnitus questionnaire, 2 tinnitus reaction questionnaire, 3 the symptom checklist (SCL-90-R, and 4 cognitive failure questionnaire (CFQ. Out of these, four were administered to all tinnitus groups while only the last two were administered on NCG. The results of these tests were compared using a t- test. Results: Participants with tinnitus reported significantly more psychological distress symptoms and everyday cognitive failures than the control group. Conclusion: Our assumption about the potential negative impact of tinnitus on psychological well-being as well as on mental concentration is supported by our study results. Implication: The present study indicates that there is a greater need for providing counseling as well as psychological intervention to reduce stress and assistance in coping with the cognitive failures for persons with tinnitus.

    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

    Full Text Available Background and Aim: Providing high quality health care is not possible without information related to the past and current condition of the patient. Records show which services, where, when and by whom was delivered. Documentation is referred to the process of precisely recording the information regarding patient care and treatment. The purpose of this study is to determine the essential data set required in audiology record keeping and designing a model for Iran.Methods: In an applied research of a descriptive-comparative type which was carried out in 2010, data elements of audiology records of domestic and foreign patient notes were used to compile a check list which was subjected to debate by Iranian audiologists in Delphi method. 110 audiologists and 17 faculty members responded to the opinion poll.Results: From 51 elements which were subjected to discussion, 37 elements by more than 75 percent of the participants, nine elements by 50 to 75 percent of the participants and five elements by less than 50 percent of the participants, were agreed upon. The only element to be considered more important by faculty members than audiologists was "Gender" (p=0.018. Seventy percent of the participants valued the effectiveness of information in patient records very high.Conclusion: The minimum data set for audiology records must include demographic information, past medical history, patient assessment and treatment plan. With reference to record design principles this information was used to develop amodel for patient audiology record which also included the necessary instructions for completing it.

    Full Text Available Aim: Children with multiple disabilities have combination of various disabilities. Accurate hearing evaluation is difficult in this population. Audiologists, generally employ a test battery approach, which includes combining findings of parent impression with behavior observation audiometry (BOA as well as auditory brainstem evoked responses (ABR findings. This study was carried out to find if there exists a correlation among various steps in the test battery for children with multiple handicaps as well as to find out, which disability is the most common among this population. Methodology: A total of 103 numbers of children with multiple handicaps were chosen at random who were referred to C U Shah Institute of Audiology and Speech Therapy for audiological assessment. The three steps involved in assessment that is parental impression, BOA and ABR findings were taken into account. The relationship was obtained using data analysis. Results: It was found that among children with multiple handicaps referred for audiological assessment, mental retardation was the most common (32.03%. Furthermore, it was found that there were more contradictory findings between parent impression and ABR (48% when compared with parent impression with BOA (38%. In between BOA and ABR contradictory findings were found in 41% of cases. Conclusion: There are wide contradictions among various steps involved in assessment of children with multiple handicaps. Implication: Audiologist should use a test battery approach to assess hearing ability of this population and audiologists should interpret findings carefully at each level.

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

    Full Text Available Background: To counter the global increase in infection-related deaths, infection control has recently developed into an active area of research. Many diseases can be prevented by infection control. In the confines of the audiology clinic, cross-contamination by micro-organisms associated with opportunistic infections remains a real concern.Objective: The primary aim of the study was to ascertain the methods that audiologists in South Africa use to prevent and control the spread of infections during and after consultation with clients.Method: A survey study was conducted, using a self-administered questionnaire. Fifty currently practising audiologists participated in the study.Results: The majority (84%; n = 42 of respondents acknowledged the importance of hand hygiene for the purpose of infection control, with 76% (n = 38 making use of no-rinse hand sanitisers. Approximately a third of audiologists wear gloves during procedures such as otoscopy and immittance, and while handling hearing aids. Disinfecting audiological equipment seem to be the preferred choice of infection control, with only 60% (n = 30 of respondents sterilising audiological equipment after each individual patient consultation. Less than half of the respondents disinfected touch surfaces and toys in the reception area.Conclusions: Based on the results, further education and training should focus on measures implemented in infection control, awareness of possible risk factors at work settings, and vaccination as an effective means of infection control.

    The early identification of pre-lingual deafness is necessary to minimize the consequences of hearing impairment on the future communication skills of a baby. According to the most recent international guidelines the deafness diagnosis must occur before the age of three months and the prosthetic-rehabilitative treatment with a traditional hearing aid should start within the first six months. When a Cochlear implant becomes necessary, the treatment should start between the age of 12 months and 18 months. The only way to diagnose the problem early is the implementation of universal neonatal audiological screening programs. Transient evoked otoacoustic emissions (TEOAE) is the most adequate test because it's accurate, economic and of simple execution. Automatic auditory brainstem response (AABR) is necessary to identify patients with auditory neuropathy but it is also important to reduce the number of false-positives.The 20-30% of infant hearing impairment is represented by progressive or late-onset hearing loss (HL) so it's also necessary to establish an audiological follow up program, especially in infants at risk.From November 2005 all neonates born in the University hospital of Pisa undergo newborn hearing screening. From 2008 the screening program follows the guidelines for the execution of the audiological screening in Tuscany which have been formulated by our group according to the 2007 JCIH Position Statement and adaptated to our regional reality by a multidisciplinary effort. From November 2005 to April 2009 8113 neonates born in the Neonatal Unit of Santa Chiara Hospital (Pisa) have undergone newborn hearing screening. 7621 neonates (93.9%) without risk factors executed only the TEOAE test. 492 (6.1%) neonates had audiological risk factors and thus underwent TEOAE and AABR. 84 patients (1,04%) failed both TEOAE and AABR tests. 78 of them underwent further investigations. 44 patients resulted false positives (the 0,54% of the screened newborns). 34 neonates

    Full Text Available The diagnosis, work-up, and treatment of sudden sensorineural hearing loss and sudden vestibular loss vary widely between units. With the increasing access to both magnetic resonance imaging and objective vestibular testing, our understanding of the various aetiologies at hand is increasing. Despite this, the therapeutic options are limited and without a particularly strong evidence base. We present a rare, yet increasingly diagnosed, case of intralabyrinthine haemorrhage (ILH together with radiological, audiological, and vestibular test results. Of note, this occurred spontaneously and has shown partial recovery in all the mentioned modalities.

    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.

    In this study, the association between the middle ear mucosal condition and post-tympanoplasty audiologic outcome was investigated in patients with chronic otitis media without cholesteatoma. One hundred and forty-three patients with chronic otitis media were collected in the Department of Otorhinolaryngology-Head and Neck Surgery at Asan Medical Center between January, 2009 and December, 2011. In the course of tympanoplasty, the status of the middle ear mucosa was divided into normal or abnormal by one surgeon. Pure tone audiometry was performed preoperatively and postoperatively, and post-tympanoplasty tympanogram was also conducted to estimate the condition of middle ear cavity. Of the 143 patients, there were 73 patients with normal middle ear mucosa and 70 patients with abnormal middle ear mucosa around Eustachian tube opening. The mean ABG of subjects with normal middle ear mucosa was 20.1 dB preoperatively, and 9.7 dB postoperatively (p ear mucosa group (p = 0.137). Postoperative ABGs for 500 and 1000 Hz (7.1, 7.7 dB) in normal middle ear mucosa patients were significantly lower than those (17.2, 19.4 dB) in abnormal middle ear mucosa patients (p ear mucosa status and post-tympanoplasty audiologic outcomes. The better condition of middle ear ventilation, the better postoperative hearing thresholds revealed after tympanoplasty.

    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.

    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.

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.

Auto - immunity is described as an etiology of Sudden or Progressive Sensory neural Hearing Loss ; similarly auto - immunity is described as an etiology for many skin diseases like Psoriasis , De rmatomyositis etc ., and the present study evaluates hearing thresholds in patients with auto - immune skin disorders . Auto - immunity is the etiology for both these conditions , causes many changes in the micro vasculature of the various organs and produces imm une complexes in the body . Hence evaluation of other organs in the presence of clinically evident autoimmune disease in one organ will guide the clinician for early diagnosis of auto immunity . So the patients with alopecia areata , Dermatomyositis , Psoriasis , Systemic sclerosis , Systemic Lupus Erythematoses , Vitiligo , Epidermolysis Bullosa and scleroderma are included in the present study for hearing evaluation . MATERIALS AND METHODS : 124 Patients attending the department of Dermatology and diagnosed with the following diseases are included in the present study ; 1 . Alopecia areata 2 . Dermatomyositis 3 . Psoriasis 4 . Systemic sclerosis 5 . Systemic Lupus Erythematoses 6 . Vitiligo 7 . Epidermolysis Bullosa . This is a prospective study conducted at GGH , Kur nool , and Andhra Pradesh . The diagnosis of the clinical entities included in this study is done according to clinical and Histopathological findings . The patients are referred from the Department of Dermatology for evaluation . After thorough history taking , the Patients are subjected for ENT examination . Pure Tone Audiometry at 250 , 500 , 1 , 000 , 2 , 000 , 4 , 000 , 6 , 000 and 8 , 000 Hz is done followed by Impedance audiometry ; including tympanometry and acoustic reflexes are done .

    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.

    Speech discrimination scores under noise circumstances were studied by use of the middle ear implant (MEI) and the conventional hearing aid (HA, HA-33, RION, Co, Ltd). The studies were performed in 10 patients implanted with the MEI and in 12 adult volunteers with normal hearing as a control. The tests were carried out using Japanese monosyllabic lists from 57S-speech discrimination test list as a test sound and multi-talker noise as a noise source. A speaker was placed in front of a subject in one meter apart. Sound characteristics of HA were adjusted as far as possible to those of the MEI by use of a sound equalizer. The intensity of speech sound pressure was adjusted at 65dB SPL, while that of the noise was changed to 65, 70 and 75dB SPL in the position of patients. Audiological evaluation of the MEI, the HA and control obtained by percentages of correct answers to 50 words in speech discrimination test with and without noise (65, 70, 75dB SPL). When the test was performed without noise, speech discrimination scores by the MEI and the HA were either 96.8 +/- 3.6% and 94.8 +/- 4.1%. However, under noise circumstances (65dB SPL) that by both devices were either 81.6 +/- 9.1% and 66.8 +/- 10.6% (P less than 0.001). When the intensity of the noise increased to 70 and 75dB SPL, speech discrimination scores by both devices deprecated together with consistent difference (P less than 0.01). Moreover speech discrimination scores by the MEI were almost same as control.(ABSTRACT TRUNCATED AT 250 WORDS)

    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.

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

    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.

    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.

    Full Text Available INTRODUCTION Interpersonal communication, day to day activities, learning language and acquiring grades in the school are important parts in the life of school going children. Unilateral or bilateral Loss of hearing affects education and the child feels handicapped socially, emotionally, and scholastically. Such children lose grades and retained in the same class affecting them emotionally. The present study was conducted in order to find out the various causes of unilateral Sensorineural Hearing Loss (USNHL in children and to study role of various audiological findings in diagnosing the cause of impaired hearing in children. AIMS AND OBJECTIVES To find out the possible etiological causes and study the role of various audiological tests in finding the causes of unilateral impaired hearing in children. MATERIALS AND METHODS A prospective study was conducted in the Department of ENT of a tertiary Hospital attached to a Medical College in Warangal, Telangana. A total of 346 children aged between 4 and 15 years attended presenting with complaints of impaired hearing. Among them 73 children with unilateral sensorineural deafness were included in the study. After a thorough ENT examination subjective tests like pure tone audiometry and behavioral observation audiometry and objective tests like impedance audiometry, Oto-acoustic emissions (OAE, and brainstem evoked response audiometry (BERA were performed. RESULTS While identifying the possible etiological cause of USNHL, OAE revealed 56.16% REFER and 43.83% PASS results. Impedance audiometric results showed 71.22% as Type A Tympanogram. Pure tone audiometric results were mostly showed severe and profound hearing losses together accounting to 87.66%. BERA findings were mostly on severe and profound hearing loss (90.40%. No children with syndromic or cranio-facial abnormalities were found. CONCLUSIONS A prospective Hospital based study of school children with USNHL showed acquired nature of the

    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.

In this article, we have analyzed some Epidemiologic Characteristics, clinical features, audiological Characteristics, and other findings in routine serological tests and MRI of 48 cases with SSNHL ,who came or were referred to us in the past 2 years. Study design: Cross sectional. Materials and Methods: In 48 patients with chief complaint of SSNHL, from June 2003 to Feb. 2005, who were admitted in clinic of otolaryngology- in Kashani Hospital -Isfahan- Iran, physical examination and history taking, audiological evaluation, MRI,and serological tests were performed in a similar way , and data were analyzed by SPSS software. Results: From 48 cases(M:28 ,F:20 with mean age of 40.9(+/-15.9 years, left ear was involved in 26 cases (54.1% ,and right ear in 19 cases (39.5% ,and in 3 cases (6.3%,both sides were involved. The severity of hearing loss was “subjectively” HIGH in 78% of patients, and the mean threshold of hearing had been calculated as 69 dB. The most common pattern in pure tone audiometry curves ,was ‘flat pattern’(75% ,and then ,’down sloping pattern’(16%.The most adjunctive clinical symptom was “tinnitus”(in 78.7%, and 40% of patients had “true vertigo”. 44.4% of our patients had some evidences of upper respiratory tract infections (URIs during recent 2 weeks. Positive family history, smoking, alcohol intake ,oral contraceptive and ototoxic drugs consumption were uncommon. 24% of cases (11 of 39 had increased ESR, and 100% of 39 patients had negative VDRL. Diabetes mellitus was the most common underlying disease (in 6 cases.From 20 patients ,who were succeeded to perform brain and ear MRI, 2 cases had tumor in internal auditory canal and cerebellopontine angle.

    Full Text Available While most tinnitus cases have some degree of hearing impairment, a small percent of the patients admitted to Ear, Nose and Throat Clinics or Hearing Evaluation Centers are those who complain of tinnitus despite having normal hearing thresholds. Present study was performed in order to better understanding of the probable causes of tinnitus and to investigate possible changes in the cochlear and auditory brainstem function in normal hearing patients with chronic tinnitus. Altogether, 63 ears (31 ears with tinnitus and 32 ears without tinnitus were examined. The prevalence of transient evoked otoacoustic emissions and characteristics of the auditory brainstem response components including wave latencies and wave amplitudes was determined in the two groups and analyzed with appropriate statistical methods. There was no difference between the prevalence of transient evoked emissions in the two groups. The mean difference between absolute latencies of waves I, III and V was less than 0.1 ms between the two groups that were not statistically significant. Also, the interpeak latency values of I-III, III-V and I-V in both groups had no significant difference. Only the V/I amplitude ratio in the tinnitus group was significantly larger than the other group (p =0.04. The changes observed in amplitude of waves, especially in the later ones, can be considered as an Audiologic finding in normal hearing tinnitus subjects and its possible role in generation of tinnitus in these patients must be investigated.

    Full Text Available Abstract Background Multi-drug resistant tuberculosis has emerged as a significant problem with the resurfacing of tuberculosis and thus the need to use the second line drugs with the resultant increased incidence of adverse effects. We discuss the effect of second line aminoglycoside anti-tubercular drugs on the hearing status of MDR-TB patients. Methods Sixty four patients were put on second line aminoglycoside anti-TB drugs. These were divided into three groups: group I, 34 patients using amikacin, group II, 26 patients using kanamycin and group III, 4 patients using capreomycin. Results Of these, 18.75% of the patients developed sensorineural hearing loss involving higher frequencies while 6.25% had involvement of speech frequencies also. All patients were seen again approximately one year after aminoglycoside discontinuation and all hearing losses were permanent with no threshold improvement. Conclusion Aminoglycosides used in MDR-TB patients may result in irreversible hearing loss involving higher frequencies and can become a hearing handicap as speech frequencies are also involved in some of the patients thus underlining the need for regular audiologic evaluation in patients of MDR-TB during the treatment.

    Full Text Available Audiologists and speech-language therapists working in developing contexts like South Africa have the opportunity to address a range of needs through their research. One of these needs is the development of assessments and therapy materials that are appropriate for their clients’particular language needs and cultural background. This editorial paper aims to introduce original research in speech-language therapy and audiology, which has been carried out in South Africa and other developing contexts and is presented in this volume of the journal. In addition we suggest that while the focus of much research is on the destination or end product that is developed, there is a need to share the methodologies that are used to reach that goal so that more research can be carried out by a wider pool of students, researchers and clinicians. We describe some of the methods that we have used in our research – often in small scale projects with budgetary constraints, which would be feasible for clinicians in their routine clinical contexts. Our hope is that others can build on these approaches, critique and share their own strategies for the ultimate advancement of the professions in southern Africa.

    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.

    From 1989 to 1993, "Oye, Amigos!" a combined group of hearing health and other medical professionals performed 18 humanitarian medical and audiologic trips to Tepic, Nayarit, Mexico. The group saw 1500 patients, issued over 800 hearing aids, and performed 150 surgeries on 123 patients. Our tympanoplasty success rate, defined as an intact tympanic membrane, was 41% during the first 2 years of the project but increased to 74% during the last 3 years. Two hundred eighteen patients who were candidates for surgery did not return for care. We present the lessons learned from the surgical care and overall management of this project, and present suggestions to improve future projects.

    Full Text Available Background: The objective of this study was to describe the audiologic and related characteristics of a group patient with speech perception affected out of proportion to pure tone hearing loss. 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

Methods Audiologic, nephrologic and opthalmologic findings in 43 cases of Alport syndrome be-tween 2007 and 2013 were reviewed. Their progress was followed up by telephone interview. Results For-ty-three individuals (36 males, 7 females, aged from 22 months to 13 years) underwent audiologic tests, which showed normal hearing in 33 and hearing loss in 10. Of these children with AS, 23.2%(all male) had sensori-neural hearing loss (70%at moderate hearing loss level). Audiometric configuration was“U”-shaped in 7, slop-ing in 2 or flat in 1 patient, respectively. Sensorineural hearing loss was asymmetric in 30%of these patients. For AS children with abnormal hearing, there were more severe podocyte injury as compared with those with normal hearing. Telephone follow-up found that one-third of AS children with normal hearing gradually devel-oped hearing loss, and hearing in those with abnormal hearing became progressively worse. One child with se-vere hearing loss developed end stage renal disease (ESRD). Conclusion Hearing loss is a common symptom of AS, which may reflect the severity of podocyte lesions. Audiometric configuration distribution in AS may vary and can be asymmetric. Children with AS all showed continuing progressive hearing loss.%目的:探讨儿童Alport综合征(Alport Syndrome AS)听力学特点多样性及预后。方法分析2007-2013年北京儿童医院确诊的43例AS患者的听力学特点,病理改变及临床特点并进行电话随访,并进行统计学分析。结果43例诊断为AS儿童中男性36例,女性7例,年龄22个月-13岁,中位数年龄8岁,听力正常组33例,听力异常组10例。①23.2%AS患儿合并感音神经性聋,并且全部为男性,中度聋最常见占70%;②听力曲线图包括谷型7例(70%)、陡降型2例(20%)、平坦型1例(10%);其中有30%听力曲线呈非对称分

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.

    Full Text Available Introduction: The hallmark of vitiligo is the disappearance of melanocytes from the skin due to an as yet unidentified mechanism. The presence of melanocytes in the auditory apparatus suggests that this system could possibly be affected by vitiligo, which targets the melanocytes of the whole body and not just the skin.The purpose of this study was to assess the incidence of auditory alterations in patients with vitiligo Materials and Methods: A total of 21 patients diagnosed with vitiligo were enrolled in this study. A group of 20 healthy subjects served as a control group. Pure tone audiometry (PTA and measurements of auditory brain stem responses (ABR were carried out in all participants. Results: High frequency sensory neural hearing loss was detected in 8 patients (38.09%. Analysis of ABR revealed that 10 patients (47.61% had an abnormal increase in the latency of Wave III and 6 (28.57% had an abnormal prolongation of the inter peak latency between Wave I and III. There was no correlation between age, duration of disease, and any of the recorded parameters. Conclusion: This study highlights the involvement of the auditory system in patients with vitiligo, suggesting that vitiligo is a systemic disease rather than a purely cutaneous problem.

    Objective Compare and analyze the audiology data (PTA'and DPOAE) in pilots under physical examination for modification to equipment of high performance aircrafts,in order to get preliminary understanding of hearing difference of the pilots from types of aircraft. Methods We collected the audiology data of 82 pilots who accepted physical examination for modification to equipment of high performance aircraft in our hospital. Eighty- two cases were divided into two groups according to the type of aircraft (41 cases in helicopter group and 41 cases in fighter group). We investigated the difference of PTA(250~8 kHz)and DPOAE(1~8 kHz)results between these two groups. Results All the pilots got the flying qualification for the high performance aircraft. In all the tested frequency, binaural average hearing threshold and DPOAE amplitude were within the normal range. The PTA difference between the two groups was not statistically significant. At 3 kHz and 4 kHz, the difference of right ear DPOAE amplitude between the two groups was statistically significant, but had no clinical significance. The incidence of abnormal high frequency PTA between the two groups had no statistically significant difference. But the incidence of abnormal high frequency DPOAE had statistically significant difference. There was a higher incidence of abnormal high frequency DPOAE in fighter pilots. Conclusion There were no significant differences in hearing between the helicopter and fighter pilots under physical examination for modification to equipment of high performance. But in fighter pilots more likely had potential hearing loss. This may be related to the stronger protection awareness in helicopter pilots.%目的 比较改装体检直升机与歼击机飞行员听力学检查结果,初步了解不同机种飞行员的听力差异.方法 对进行改装体检的直升机和歼击机飞行员各41名进行纯音听阈和畸变产物耳声发射检查,比较两组结果.结果 根据《中

    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.

    crianças.INTRODUCTION: The Rubinstein-Taybi Syndrome was first described in 1963 when the authors presented seven children with mental and growth retardation, broad thumbs and big toes, associated to face anomalies. Years later new publications characterized other physical anomalies. The incidence in the general population is one in 300.000 borns and the aetiology is unknown until now. The purpose of this study was to present the clinical manifestations, physical anomalies and the audiologic evaluation of five children with Rubinstein-Taybi Syndrome. REPORT OF CASES: Five children with Rubinstein-Taybi Syndrome were evaluated by main clinical manifestations, physical anomalies and audiologic evaluation. The main clinical and physical manifestations were: mental retardation, short stature, short and broad fingers, beaked nose, high palate, irregular placement of teeth and poor speech development. The auditory acuity was evaluated by tonal audiometry, tympanometry and auditory brainstem response (ABR. DISCUSSION: The physical characteristics presented by the patients with Rubinstein-Taybi Syndrome facilitate the diagnosis and are responsible for otolaryngological and phonoaudiological symptoms, like airway infections, nasal obstruction, otitis media, tonsillar hyperplasia, deafness, perioral hypotonia and dysphagia. The cognitive impairment is responsible to speech delay and learning disabilities. CONCLUSION: The presence of otolaryngologic and phonoaudiologic symptoms in patients with Rubinstein-Taybi Syndrome permit specialists to make early diagnoses and treatment.

    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.

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

    Full Text Available A deficiência auditiva como déficit sensorial mais comum tem dentre suas diferentes etiologias as alterações genéticas. Assim, é importante que a investigação audiológica se associe à busca do diagnóstico etiológico. OBJETIVO: Relatar o perfil audiológico e genético de três irmãos portadores de deficiência auditiva neurossensorial não-sindrômica. MATERIAL E MÉTODO: Estudo de caso de três irmãos, do sexo masculino, com 3, 5 e 16 anos, respectivamente, submetidos à avaliação audiológica comportamental e eletrofisiológica, e estudo molecular. RESULTADOS: Os achados audiológicos mostraram: audiometria do tipo neurossensorial, bilateral, simétrica, de grau moderado a moderadamente severo e configuração descendente acentuada. EOAT e EOAPD ausentes nos dois irmãos mais novos. PEATE compatível com perda auditiva moderadamente severa a severa. Presença do P300 com latências dentro da normalidade bilateralmente no irmão mais velho. Os achados do exame molecular mostraram que as duas crianças mais novas eram heterozigotos para a mutação 35delG no gene GJB2 e o mais velho não apresentava essa mutação. CONCLUSÃO: A associação das avaliações fonoaudiológicas e genéticas permite o diagnóstico etiológico de perdas auditivas que à primeira vista são semelhantes, mas que não obedecem à mesma estrutura genética. Os estudos moleculares devem ser abrangentes, evitando diagnósticos precipitados que prejudiquem o aconselhamento genético.Hearing loss is a multifaceted condition with many etiologies, among which genetic mutation is. Therefore, it is important to connect audiological investigation to etiological diagnosis.

    Full Text Available Introduction: Based on the hypothesis that neurovascular events involving in the pathophysiology of migraine can cause hearing loss by influencing blood flow of inner ear, it was aimed to determine whether migraine with or without aura in our clinics patients are at risk for hearing loss by assessing hearing levels via a high-frequency audiometry, acoustic reflex and transient otoacoustic emission responses; to discriminate whether hearing loss is cochlear or retrocochlear originated, if present; and to evaluate whether or not migraine treatment affect hearing level in patients received treatment for migraine in this study. Materials and Methods: The study included patients who were diagnosed as migraine between December 2011 and December 2012 at Neurology Department of Cumhuriyet University, Medicine School according to ICD-II classification and accepted to receive medical therapy. In all patients, hearing levels were measured at baseline and after treatment by using high-frequency audiometry, transient otoacoustic emission and acoustic reflex tests. Results: In the present study, hearing thresholds measured in the right ear was normal in migraine patients with or without aura at baseline, while mild hearing loss was detected in right ear at the frequency of 500 Hz after treatment when hearing thresholds at different frequencies were compared. This difference was significant (P 0, 05. Conclusion: Differently from literature, hearing loss in our patients developed at lower frequencies and after treatment. The results we obtained from our study also presented that there might be a relationship between migraine disease and sensorineural hearing loss.

    Full Text Available 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.

    Various materials such as fascia, perichondrium, and cartilage have been used for reconstruction of the tympanic membrane in middle ear surgery. Because of its stiffness, cartilage is resistant to resorption and retraction. However, cartilage grafts result in increased acoustic impedance, the main limitation to their use. The aim of this study was to compare the hearing results after cartilage tympanoplasty versus fascia tympanoplasty. This study included 114 patients without postoperative tympanic membrane perforation who underwent tympanoplasty type I between 2007 and 2010, 31 with fascia and 83 with cartilage. Preoperative and 1 year postoperative air-bone gap (ABG) and postoperative gain in ABG at frequencies of 0.5, 1, 2, and 3 kHz were assessed. Both groups were statically similar in terms of the severity of middle ear pathology and the preoperative hearing levels. Overall, postoperative successful hearing results showed 77.4% of the fascia group and 77.1% of the cartilage group. Mean postoperative gains in ABG were 9.70 dB for the fascia group and 9.78 dB for the cartilage group. These results demonstrate that hearing after cartilage tympanoplasty is comparable to that after fascia tympanoplasty. Although cartilage is the ideal grafting material in problematic cases, it may be used in less severe cases, such as in type I tympanoplasty, without fear of impairing hearing.

    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.

    Full Text Available Objective. 312 tinnitus sufferers were studied in order to analyze: the clinical characteristics of tinnitus; the presence of tinnitus-age correlation and tinnitus-hearing loss correlation; the impact of tinnitus on subjects' life and where possible the etiological/predisposing factors of tinnitus. Results. There is a slight predominance of males. The highest percentage of tinnitus results in the decades 61–70. Of the tinnitus sufferers, 197 (63.14% have a hearing deficit (light hearing loss in 37.18% of cases. The hearing impairment results of sensorineural type in 74.62% and limited to the high frequencies in 58.50%. The tinnitus is referred as unilateral in 59.93%, a pure tone in 66.99% and 10 dB above the hearing threshold in 37.7%. It is limited to high frequencies in 72.10% of the patients with sensorineural hearing loss (SNHL while the 88.37% of the patients with high-frequency SNHL have a high-pitched tinnitus (2=66.26;<.005. Conclusion. Hearing status and age represent the principal tinnitus related factors; there is a statistically significant association between high-pitched tinnitus and high-frequency SNHL. There is no significant correlation between tinnitus severity and tinnitus loudness confirming the possibility that neural connection involved in evoking tinnitus-related negative reactions are governed by conditioned reflexes.

    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.

    Full Text Available The relationship between diabetes mellitus (DM and hypoacusia has been discussed since the work of Jordao, in 1857. Type II diabetes was considered a prevalent age-related medical condition, resulting in subclinical pathological changes. It was estimated that the incidence is about 9.6% of people in USA. (Cowie et al. 2006. Some studies has shown that the magnitude of hearing loss in patients with DM is related to the duration of the disease, age, and affects the auditory threshold to high frequencies. (Frisina et al. 2006. In a study of Tay HL et al. (1995 was found that there is a possible correlation between the duration of diabetes and hearing loss. The auditory system requires glucose and high-energy utilization for its complex signal processing. This suggests that the cochlea may also be a target organ for the ill effects of hyperglycemias. (Cullen and Cinnamond, 1993. Increased glucose exposure, even for short periods, initiates a metabolic cascade that could disrupt the cochlea both anatomically and physiologically (Jorgensen, 1961. Hearing depends on small blood vessels and nerves of the inner ear that are affected by high blood sugar level in diabetic patients. Outer hair cells modulate auditory reception in the inner ear: consequently, OAEs are commonly considered a useful index of cochlear function...

    1990-09-01

    The hearing loss of Ludwig von Beethoven has fascinated physicians, audiologists, and musicologists for almost 200 years. In this review of the literature, the features, treatment, and differential diagnosis of the composer's malady are discussed. An original series of hypothetical audiograms and actual photomicrographs depicting cochlear otosclerosis and Paget's disease are also provided. The author concludes with the majority of otologists that cochlear otosclerosis is the most likely diagnosis for the hearing loss. In addition, a summary of Beethoven's complicated medical history and results of the autopsy that confirmed chronic liver disease are included.

    : 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.

    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.

    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.

    2012-01-01

    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.

    Full Text Available Objective: Aim of this study was to show the effects of rheumatoid arthritis (RA on auditory system using pure tone audiometer and tympanometric assessments and to compare these values with healthy controls. Methods: This study included 107 subjects: 57 RA pa­tients who were being followed at our clinic with a RA diagnosis and 50 healthy controls who had similar age and gender properties. Besides clinical and laboratory findings audiometric, and tympanometric tests and sta­pes reflex measurements were compared for all patients. Results: Results of this study showed statistically signifi­cant differences in air conduction thresholds at 0.5, 1, 2, 4, and 6 kHz frequencies between RA patients and con­trols. In RA patients, bone conduction was affected only at 4 kHz and more in left ear. Additionally, air-bone conduc­tion differences were significant except at 2 kHz. Although air-bone conduction difference was higher in the study group than the control group, this was not statistically sig­nificant. Similarly no significant difference was detected in stapes reflex and tympanometric measurements between RA patients and healthy controls statistically. Conclusion: This study showed that conduction type hearing loss is seen more frequently in RA patients and bone conduction is affected at high frequencies in particu­lar. Moreover, No significant differences were seen in sta­pes reflex, compliance and pressure measures between groups. J Clin Exp Invest 2016; 7 (1: 63-68

    Full Text Available ABSTRACT INTRODUCTION: This cross-sectional comparative study was carried out at the Diabetes outpatient clinic of LAUTECH Teaching Hospital (LTH Ogbomoso, Nigeria. OBJECTIVE: This study assessed patterns of otologic diseases and auditory acuity among type 2 diabetics and determinants of these findings among diabetics. METHODS: Ninety-seven consenting patients with clinical diagnosis of diabetes mellitus (194 ears were matched for age and sex with ninety non-diabetic patients (180 ears. These patients were screened using otoscopy and pure tone audiometry over a 6-month period. RESULTS: The study reported a crude prevalence rate of 21.6% hearing loss in T2DM patients. The most common type of otologic disease that showed significant association with T2DM patients was otitis media with effusion (p = 0.027. T2DM was significantly associated with abnormal audiometric findings (p = 0.022, particularly sensorineural hearing loss (p = 0.022, of the moderate grade (p = 0.057. There were no differences of the audilogical findings for any particular ear, and no differential affectation of frequency range was observed. Coexisting hypertension and poor glycaemic control were significantly associated with aggravation of the hearing of the T2DM patients (p < 0.001, and p = 0.009 respectively. CONCLUSION: T2DM had appreciable effects on hearing acuity. T2DM was significantly associated with the type and the degree of the hearing loss. The need for screening of hearing acuity of T2DM patients, in order to detect early changes, and promptly offer an adequate management and remedial measures was emphasized in this study.

    Neuromyelitis optica (NMO) is an autoimmune astrocytopathy caused by anti-aquaporin 4 antibody. Only two patients with NMO have been reported presenting with hearing disorders to our knowledge. We recently treated a 40-year-old woman with NMO complaining of right hearing loss. Audiometry showed minimal asymmetry, but the auditory brainstem responses (ABR) were severely attenuated on the right. The attenuated ABR and her aural symptoms (hearing loss and fullness) improved after steroid treatment. The present case shows that the retrocochlear-type hearing loss may be associated with NMO.

    Full Text Available Abstract 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.

    Full Text Available We studied 49 patients with partial epilepsy divided into lesional cases (i.e. with lesions on CT scan and non-lesional cases (i.e. without CT scan lesions, in relation to the Wechsler Intelligence Scale subtests (Coding, Digit span, dichotic listening CV task and Central Auditory Test (SSI, PSI. The aim of this paper was to study the hemispheric prevalence in dichotic listening task with regard to cognitive perforamance, as well as the presence or absence of central auditory dysfunction. Lesional cases presented a hemisphere prevalence in dichotic listening task with regard to cognitive performance, as well as the non-lesional cases tend to report the stimuli in the same side of EEC focus. Significant differences were found among the lesional and non lesional cases in relation to the digit span score and Coding subtest in right lesional cases versus right non-lesional cases. Both lesional and non-lesional group showed signs of central auditory dysfunction. We suggest that the dichotic listening and SSI and PSI test can be useful for a best comprehension of asymmetric neuropsychological performance in partial epilepsy.

    Full Text Available OBJETIVO: Revisar a literatura sobre a perda auditiva associada ao envelhecimento e suas implicações, numa perspectiva atual. REVISÃO DA LITERATURA: Nos estudos realizados no Brasil, a presbiacusia vem sendo apontada como causa mais freqüente da deficiência auditiva em pessoas idosas, implicando em uma dificuldade de compreensão durante a comunicação verbal. Estudos internacionais também mostram alta prevalência da perda auditiva em pessoas idosas. DISCUSSÃO: Segundo pesquisas recentes, à medida que o quantitativo da população idosa vem aumentando, também aumenta a prevalência da presbiacusia que interfere na qualidade de vida do idoso. Mesmo entre os profissionais de saúde, ainda é grande o desconhecimento em relação às vantagens e ganhos que a reeducação auditiva específica para idosos com perda auditiva pode oferecer. CONCLUSÃO: Os artigos aqui analisados mostraram que os serviços de saúde da rede pública, que envolvem médicos e fonoaudiólogos, devem estabelecer diretrizes para o desenvolvimento de programas de diagnóstico, aquisição de aparelhos de amplificação sonora individual e, principalmente, de reeducação auditiva para os idosos portadores de presbiacusia, para que eles possam participar e desfrutar das relações sociais, mantendo uma boa qualidade de vida. Entretanto, no Brasil, os estudos e pesquisas nesta área estão apenas começando.AIM: to review the literature on aging-related hearing loss and its current impacts. LITERATURE REVIEW: In studies carried out in Brazil, presbycusis has been blamed for being the most frequent cause of hearing loss in the elderly, causing verbal communication impairment. International studies also show the high prevalence of hearing loss in the elderly. DISCUSSION: According to recent investigations, as the number of elderly people increase, the prevalence of presbycusis interfering in the life quality of this population also increases. Even among health care professionals, there is a huge lack of knowledge about the advantages and gains a specific hearing reeducation can bring about for the elderly with hearing impairment. CONCLUSIONS: the papers hereby analyzed showed that the public health care centers with physicians and speech and hearing therapists, should establish the guidelines for the development of diagnostic programs, purchase of hearing aids and, most specially, hearing reeducation for the elderly with presbycusis, so that they may enjoy their social relations, and thus enhance their life quality. However, in Brazil, studies and research in this area only beginning.

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

    Directory of Open Access Journals (Sweden)

    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.

    Rosenhamer, H J; Lindström, B; Lundborg, T

    1981-01-01

    Interaural latency differences (ILDs) of wave V of the brainstem electric response (BSER) were studied (1) in 20 normal-hearing subjects at 90, 80, 60 and 40 dB HL click level, (2) in 22 patients with symmetrical cochlear hearing loss at 90 dB HL, corresponding to 45-80 dB SL, and (3) in 45 patients with asymetrical cochlear hearing loss with interaural recruitment, at 90 dB HL on one hand and at a click sensation level corresponding to 90 dB HL in the poorer ear (range 10-75 dB SL) on the other hand. In the normal hearing group the ILDs did not exceed 0.2 ms except in one case at 40 dB HL (0.3 ms). In the symmetrical cochlear loss group the ILD did not exceed 0.2 ms in any patient. In the asymmetrical cochlear loss group the ILD at 90 dB HL exceeded 0.2 ms in 12 cases, but only in four cases after correction for pure tone hearing loss at 4 kHz by 0.1 for each 10 dB above 50 dB HL; at equal sensation levels the ILDs were all zero or negative meaning that the wave V latency was shorter on stimulation of the poorer ear. Assuming ILD to be a valid discriminator between cochlear and retrocochlear lesions, the corrected ILD at equal click hearing levels (90 dB HL), with the critical value set at 0.2 ms, thus gave a 9% false-positive rate whereas the ILS at equal sensation levels, with the critical value set at zero, gave no false-positives. It still remains to be shown that the latter criterion will not increase the number of false-negative results in retrocochlear lesions.

    Swallowing disorders are frequent. The main concern is mortality due to aspiration-induced pneumonia and malnutrition. In addition, 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 phoniatricians are asked for diagnostics and therapy, and will coordinate the interdisciplinary treatment according to the endoscopic findings. A differentiated approach in history, diagnostics, and symptom-oriented treatment is necessary for these mostly complex disorders. Integration of non-medical staff such as speech therapists, 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 in close cooperation. In particular, an interdisciplinary cooperation with the staff of intensive care medicine is essential. 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 excluded.

Methods A total of 126 patients were included in this study. 63 patients had MD and the remaining 63 patients with vertigo diseases. The patients were divided into 3 groups (group A,B,C). Each patient underwent glycerol test,and patients in group A,B,C were tested with conventional pure tone audiomety,ECochG and DPOAE, respectively, be fore and 1,2,3 hours after oral administration of glycerol. Results The positive rates of glycerol test in MD were significantly higher than that in other vertigo diseases. The positive incidence of pure tone audiometry glycerol test, ECochG glycerol test and DPOAE glycerol test in MD patients were 38.1%, 52. 4% and57.1%, respectively. All were dected within 2 hours after glycerol test. Conclusion The study shows that the glycerol test has diagnostic value for MD. Futhermore, ECochG glycerol test and DPOAE glycerol test are more accurate for the diagnosis of MD compared with pure tone audiometry glycerol test. We can add ECochG or/and DPOAE during the glycerol test to improve the diagnosis rate of MD.

    Full Text Available Preconiza-se o diagnóstico até os três meses de idade em crianças com deficiência auditiva congênita. Após a etapa inicial de confirmação do diagnóstico, é necessário que se obtenha limiares precisos nas diferentes frequências, para que seja possível uma adequada seleção, indicação e regulagem de aparelhos de amplificação sonora. Nesse contexto, inserem-se os Potenciais Evocados Auditivos de Tronco Encefálico por Frequência Específica (PEATE-FE e, mais recentemente, os Potenciais Evocados Auditivos de Estado Estável (PEAEE. O objetivo deste estudo de caso foi apresentar os achados das duas técnicas para estimar os limiares auditivos em uma criança de três meses de idade, com perda auditiva neurossensorial bilateral, diagnosticada utilizando-se como primeiro método de avaliação os Potenciais Evocados Auditivos de Tronco Encefálico com estímulo clique, tanto por via aérea como por via óssea. As duas técnicas mostraram-se eficientes para estimar os limiares auditivos, com uma vantagem dos PEAEE com relação ao tempo de duração de exame.It is recommended that congenital hearing loss is identified as early as three months old. After the initial step of confirming the diagnosis, it is necessary to obtain accurate hearing thresholds, allowing an adequate selection, indication and regulation of hearing aids for these children. It is inserted, in this context, the Frequency-Specific Auditory Brainstem Responses (FSABR and, more recently, the Auditory Steady-State Responses (ASSR. The aim of the present study was to describe the findings of the use of both techniques to estimate the auditory thresholds of a three-month-old infant with bilateral sensorineural hearing loss diagnosed using, as primary evaluation method, the click-evoked Auditory Brainstem Responses, with both air and bone stimuli conduction. Both techniques provided reliable findings for estimating auditory thresholds. The ASSR had an advantage regarding the duration of the evaluation.

    2016-02-01

    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.

  8. [Spectral analysis of sounds produced by musical instruments and other sounding bodies for hearing screening of children].

    Science.gov (United States)

    Ptok, M; Sesterhenn, G; Ptok, A; Arold, R

    1993-01-01

    Some time ago audiological screening in infants was mostly performed using musical instruments or equivalents. The use of acoustic evoked potentials and oto-acoustic emissions changed the strategies of hearing assessment in newborns and infants, however, musical instruments are still in use. An adequate interpretation of screening results obtained with musical instruments necessitates a profound knowledge of frequencies and intensities derived from these instruments. In this study spectral analyses of sounds from these instruments were performed. The results may be of value for those using musical instruments as a tool for audiological screening. In addition, the results show that with some instruments intensities able to cause inner ear damage can be generated.

    2005-11-01

    Full Text Available The development of hearing aids incorporates two aspects, namely, the audiological and the technical point of view. The former focuses on items like the recruitment phenomenon, the speech intelligibility of hearing-impaired persons, or just on the question of hearing comfort. Concerning these subjects, different algorithms intending to improve the hearing ability are presented in this paper. These are automatic gain controls, directional microphones, and noise reduction algorithms. Besides the audiological point of view, there are several purely technical problems which have to be solved. An important one is the acoustic feedback. Another instance is the proper automatic control of all hearing aid components by means of a classification unit. In addition to an overview of state-of-the-art algorithms, this paper focuses on future trends.

    Full Text Available Hearing impairment is recognised for its prominence among the chronic conditions of ageing, being more prevalent in Australia than all other national health priorities except musculo-skeletal conditions (Australian Institute of Health and Welfare, 2004. However despite its prevalence, there have been fewer epidemiological studies of hearing impairment than for other chronic diseases and disorders. Epidemiological data based on audiological evaluations are scant and a rigorously defined burden of illness for hearing impairment at a population or community level using both audiological and self-report types of estimate is still only available from a few studies world-wide (Gates et al., 1990; Davis, 1995; Wilson et al., 1998; Cruikshanks et al., 1998. Longitudinal studies are particularly valuable in providing information about patterns of ageing, about cohort differences in age-related physical, sensory and psychological functioning and for the services which an ageing population might require...

    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.

    The surgical rehabilitation of mixed hearing losses can be performed by coupling the floating mass transducer of the Vibrant Soundbridge to the round window. The quality of coupling the floating mass transducer to the round window is crucial for the audiological outcome. It was the aim of this study to further observe the different patterns of floating mass transducer position at the round window. We compared twenty patients with mixed hearing loss implanted with a floating mass transducer attached to the round window and 24 surgeries between 5/2007 and 6/2010. An evaluation of the chronological observation of the flat panel angiography-controlled position of the floating mass transducer at the round window with relation to the surgical report and the audiological outcome was done. We observed no changes in the mean pre- and postbone conduction thresholds. The floating mass transducer position was variable and could be radiologically classified and correlated with the audiologically outcome. A learning curve was observed from the earlier to later implantations. Postoperative, radiological evaluation of the location and angle of the floating mass transducer by means of flat panel tomography allowed us to classify the floating mass transducer position at the round window into 4 groups.

    The aim of this pilot study was to determine the acceptance and benefit from the middle ear implant system Vibrant Soundbridge(®) (VSB, MED-EL Corporation, Austria) by means of a questionnaire, compared to a previously used conventional bone conducting hearing device, in preschool children with unilateral congenital aural atresia. Prospective cohort study. All nine children with unilateral congenital aural atresia used the VSB and had previous experience with a bone conducting hearing device. The benefit from the VSB was evaluated by questionnaires concerning acceptance of hearing aids, handling, listening effort, behavior, quality of life, and the duration of daily use and compared to the experience with the bone conducting hearing device. In addition, to quantify the benefit from the VSB use, audiological assessment (pure-tone audiometry via free field testing, speech audiometry, and localization test) was performed with and without VSB. The questionnaires and audiological test results were compared pairwise. According to all questionnaire areas, children benefited significantly more from the VSB compared to bone conducting hearing device (ps VSB. Children performed significantly better with the VSB than without it in the audiological assessment. Children with unilateral aural atresia benefited significantly more from the VSB compared to a conventional bone conducting hearing device according to the parents' questionnaires and yielded better results in the audiometry and localization test with the VSB than without it.

    2002-03-01

    Surveillance data on occupational audiological disorders have been collected by the Occupational Surveillance Scheme for Audiological Physicians (OSSA) since October 1997 and by the Occupational Physicians Reporting Activity (OPRA) from January 1996. During the 3 years ending in September 2000, a total of 1620 new cases were received from consultant audiological physicians; 988 new cases were estimated from reports by occupational physicians in the period from October 1997 to September 2000. The annual incidence of occupational noise-induced hearing loss (NIHL) was 1.94 and 1.23 per 100 000 workers for the OSSA and OPRA schemes, respectively. The median age at diagnosis with NIHL was 59 years in OSSA reports and 50 years in OPRA; nearly all cases were seen in men (95.6 and 92.5% male cases for OSSA and OPRA, respectively). High incidence rates based on OSSA reports were seen in foundry labourers (64.0 per 100 000 employed), coal gas and coke oven furnace workers (54.6), workers in transport and communication (43.1), metal workers (31.3), and members of the armed forces (28.3). Data from occupational physicians point to high rates in sawyers and woodworking machinists, metal furnace workers, coach and carriage builders, maintenance fitters, and engineering labourers. Among workers aged less than or equal to45 years, those in manufacturing and the armed forces were prominent. The long latency of occupational hearing loss makes surveillance difficult, but consistent patterns in occupational risk suggest targets for preventive efforts.

    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.

    2014-06-01

    Profound idiopathic sudden sensorineural hearing loss is thought to have a poor prognosis, but few studies have focused on this condition. We aimed to assess the impact of patient factors, audiologic parameters, and salvage intratympanic steroid injection therapy on the prognosis of profound idiopathic sudden sensorineural hearing loss. The demographic, clinical, and audiologic data, degree of hearing recovery, and efficacy of intratympanic steroid injection therapy in 576 patients with profound idiopathic sudden sensorineural hearing loss (mean age 56.2 ± 14.9 years) who had been admitted at four tertiary referral centers between 2000 and 2011 were retrospectively reviewed. The mean hearing level at the initial presentation was 108.1 ± 9.5 dB. Many patients experienced vertigo (52.1%) and tinnitus (77.4%). At the 2-month follow-up, 172 (29.8%) patients showed some degree of hearing recovery, but only 21 (3.6%) patients recovered normal hearing. Further, the 116 patients who had received salvage intratympanic steroid injections showed a better audiologic outcome (improvement, 26.1 ± 24.3 vs. 15.7 ± 22.1 dB; P = 0.000) than those who had not (n = 429). In conclusion, a higher degree of hearing loss at the initial presentation indicates a poorer prognosis. Salvage intratympanic steroid injection therapy may improve the hearing of patients with profound idiopathic sudden sensorineural hearing loss after the failure of systemic steroid therapy.

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.

    Full Text Available Abstract Background Chronic suppurative otitis media (CSOM is frequently associated with symptoms of inflammation like discharge from the ear or pain. In many cases, patients suffer from hearing loss causing communication problems and social withdrawal. The objective of this work was to collect prospective audiological data and data on general and disease-specific quality of life with validated quality of life measurement instruments to assess the impact of the disease on health-related quality of life (HR-QOL. Methods 121 patients were included in the study. Patients were clinically examined in the hospital before and 6 months after surgery including audiological testing. They filled in the quality of life questionnaires SF-36 and Chronic Otitis Media Outcome Test 15 (COMOT-15 pre-operatively and 6 and 12 months post-operatively, respectively. Results Complete data records from 90 patients were available for statistical analysis. Disease-specific HR-QOL in patients with CSOM improved after tympanoplasty in all the scales of the COMOT-15. There was no difference in HR-QOL assessment between patients with mesotympanic respectively epitympanic CSOM. However, we did find the outcome to be worse in patients who received revision surgery compared with those receiving primary surgery. Audiometric findings correlated very well with the subscale hearing function from the COMOT-15 questionnaire. General HR-QOL measured with the SF-36 was not significantly changed by tympanoplasty. Conclusions Tympanoplasty did lead to a significant improvement of disease-specific HR-QOL in patients with CSOM while general HR-QOL did not change. Very well correlations were found between the subscale hearing function from the COMOT-15 questionnaire and audiological findings. Revision surgery seems to be a predictor for a worse outcome.

    CHARGE syndrome is a rare, polymalformative disease, representing one of the major causes of associated blindness and deafness. Bilateral, severe-profound, sensorineural hearing loss is common in CHARGE children. Aim of this study is to present our results in children with "CHARGE syndrome" submitted to cochlear implantation (CI). The frequency of anatomic anomalies, possible variations in the surgical technique of CI, and the audiological/rehabilitative benefits attained in our patients are reported. we submitted 5 children affected by CHARGE syndrome with profound, bilateral, sensorineural hearing loss to CI. Otoacoustic emissions, auditory brainstem response, acoustic impedance testing, cranial computed tomography and magnetic resonance were carried out preoperatively in all children. CI was performed using the mastoidotomy-posterior tympanotomy approach in two cases, and the suprameatal approach in three children. Infant toddler-meaningful auditory integration scale was used to evaluate kid's audiological performance before and after CI. Intra-operatory findings and postsurgical complications were evaluated. Among our patients, intraoperative anatomical malformations were cochlear hypoplasia (100 %), ossicles malformations (100 %), semicircular canals aplasia (100 %), oval window atresia (60 %), round window atresia (40 %), widening of the aqueduct of the vestibule (20 %), and aberrant course of the facial nerve (20 %). No intra- or postoperative complication was recorded in relation to implant positioning. After a follow-up ranging from 1 to 4.5 years, only 2/5 patients used oral language as the sole mean of communication, 1 started utilizing oral language as the main mean of communication, while 2 patients did not develop any linguistic ability. In conclusion, CI in patients with CHARGE association is feasible and, despite results variability, it should be carried out in CHARGE children with severe hearing loss as soon as possible.

    Full Text Available Objective: To determine the prevalence of occult hearing loss in elderly inpatients, to evaluate feasibility of opportunistic hearing screening and to determine subsequent provision of hearing aids. Materials and methods: Subjects (>65 years were recruited from five elderly care wards. Hearing loss was detected by a ward-based hearing screen comprising patient-reported assessment of hearing disability and a whisper test. Subjects failing the whisper test or reporting hearing difficulties were offered formal audiological assessment. Results: Screening was performed on 51 patients aged between 70 and 95 years. Of the patients, 21 (41% reported hearing loss and 16 (31% failed the whisper test. A total of 37 patients (73% were referred for audiological assessment with 17 (33% found to have aidable hearing loss and 11 were fitted with hearing aids (22%. Discussion: This study highlights the high prevalence of occult hearing loss in elderly inpatients. Easy two-step screening can accurately identify patients with undiagnosed deafness resulting in significant proportions receiving hearing aids. Key sentences Approximately 14% of the elderly population use hearing aids despite a reported prevalence of deafness in up to 55%. The use of hearing aids is associated with an improvement in physical, emotional, mental and social well-being. An easy screening test for hearing loss consists of patient-reported hearing loss and a whisper test. Opportunistic screening of elderly inpatients resulted in referral of 73% of screened patients for formal audiology. Of the screened patients, 22% were provided with hearing aids.

    Full Text Available CONTEXT AND OBJECTIVE: Some factors seem to influence speech impairment among phonologically disordered children. The aim was to compare severity indices with some correlated factors. DESIGN AND SETTING: Observational, analytical and cross-sectional study conducted within the Language-Speech-Hearing Sciences Course, Universidade de São Paulo. METHOD: Fifty phonologically disordered children with ages ranging from 4 to 11 years took part. The indices were calculated from phonology tests and were correlated with anamnesis and audiological data. Student’s t test and Spearman’s correlation were used to compare percentages of consonants correct (PCC and process density index (PDI for children with and without otitis, upper respiratory histories and audiological abnormalities, with regard to whether or not they were comprehended during assessment, their ages when they started to speak and their ages at the assessment. RESULTS: The higher the age at the assessment was, the higher the PCC (imitation: 0.468; naming: 0.431; Spearman’s correlation and the lower the PDI (imitation: 0.459; naming: 0.431; the later the child started to speak, the lower the PCC (imitation p = 0.064; naming p = 0.050 and the higher the PDI (imitation p = 0.067; naming p = 0.042. There were differences between groups with and without upper respiratory history (PCC: imitation p = 0.016, naming p = 0.005; PDI: imitation p = 0.014, naming p = 0.008. There was no difference between the groups regarding otitis, comprehension during the assessment and audiological data. CONCLUSIONS: Children with upper respiratory histories who began to speak later presented more severe speech impairment indices.

    Full Text Available Aims: To describe the auditory and language outcomes of children with early diagnosis and treatment for congenital toxoplasmosis. Methods: A cross-sectional study included all children diagnosed with congenital toxoplasmosis, through the Minas Gerais State Neonatal Screening Program, from September 2006 to March 2007. All children received early treatment, initiated before the age of 2.5 months, and were periodically assisted by a team of specialists including pediatricians, ophthalmologists and speech-language therapists and audiologists. Hearing function was evaluated with the following procedures: tympanometry, transient evoked otoacoustic emissions, distortion product otoacoustic emissions, behavioral observation audiometry, and brainstem auditory evoked potentials. Hearing function and sensitivity was estimated and audiological results were classified as normal, conductive hearing loss, sensory-neural hearing loss and central dysfunction. Language performance was assessed and classified as normal or abnormal, according to test results. The following variables were studied: audiological results, neurological and ophthalmological conditions, language performance and presence of risk indicator for hearing loss other than congenital toxoplasmosis. Univariate analysis was conducted using the chi-square or Fisher’s Exact test. Results: From September 2006 to March 2007, 106 children were diagnosed with congenital toxoplasmosis through the neonatal screening program, and were included in the study. Data analysis showed normal hearing in 60 children (56.6%, while 13 children (12.3% had conductive hearing loss, four children (3.8% had sensory-neural hearing loss and 29 children (27.4% presented central hearing dysfunction. There was association between hearing problems and language deficits.

    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.

    Head and neck cancer patients treated with high-dose cisplatin and radiotherapy will suffer from hearing deficits. The current low-dose regimen seldom causes hearing threshold decrease. Tinnitus in this patient population has not been investigated earlier. We aimed to evaluate the possible ototoxicity of low-dose (40 mg/m(2)) weekly administered cisplatin with concomitant radiotherapy. Twenty-two patients with locally advanced head and neck cancer were prospectively recruited to participate the study after treatment recommendation for chemoradiotherapy with low-dose cisplatin and intensity-modulated radiotherapy. They filled in a Tinnitus Handicap Inventory and undertook audiologic evaluations before and after treatment. Ototoxicity was determined by >10 dB threshold shift at frequencies 4 and 8 kHz or in pure tone average. A historical cohort of nine patients treated with high-dose (100 mg/m(2)) cisplatin and radiotherapy was used for comparison. After treatment, study patients demonstrated no significant changes in their hearing over frequencies 0.5-4 kHz, and the threshold shifts were minor at 4 and 8 kHz. More than 50 % of patients reported no tinnitus after treatment and the remainder only had slight to moderate tinnitus causing no interference with their daily activities. In contrast, five of the nine patients having received high-dose cisplatin reported disturbing tinnitus. Further, changes in pure tone averages were exhibited in three of these patients and six had significant threshold shifts at 4 and 8 kHz. Head and neck cancer patients treated with concomitant intensity-modulated radiotherapy and low-dose cisplatin seem to experience only minor audiological sequelae and therefore, these patients appear to require no routine audiological monitoring. Such evaluation could be performed only when needed.

    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.

    Full Text Available Speech in noise tests that measure the perception of speech in presence of noise are now an important part of audiologic tests battery and hearing research as well. There are various tests available to estimate the perception of speech in presence of noise, for example, connected sentence test, hearing in noise test, words in noise, quick speech-in-noise test, bamford-kowal-bench speech-in-noise test, and listening in spatialized noise-sentences. All these tests are different in terms of target age, measure, procedure, speech material, noise, normative, etc. Because of the variety of tests available to estimate speech-in-noise abilities, audiologists often select tests based on their availability, ease to administer the test, time required in running the test, age of the patient, hearing status, type of hearing disorder and type of amplification device if using. A critical appraisal of these speech-in-noise tests is required for the evidence based selection and to be used in audiology clinics. In this article speech-in-noise tests were critically appraised for their conceptual model, measurement model, normatives, reliability, validity, responsiveness, item/instrument bias, respondent burden and administrative burden. Selection of a standard speech-in-noise test based on this critical appraisal will also allow an easy comparison of speech-in-noise ability of any hearing impaired individual or group across audiology clinics and research centers. This article also describes the survey which was done to grade the speech in noise tests on the various appraisal characteristics.

    A 38-year-old female patient experienced a sudden onset of unilateral sensorineural hearing loss due to Moyamoya disease. A detailed summary of audiological and neurological findings indicated that the sudden hearing loss might be due to Moyamoya disease resulting in occlusion of posterior and middle cerebral arteries. Intravenous prednisolone and trimetazidine dihydrochloride may improve hearing thresholds and speech understanding. To our knowledge, this is the first article in the literature reporting a case of sudden hearing loss as the first manifestation of Moyamoya disease in a young adult.

    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).

    Inner ear malformations are frequently found in patients with congenital hearing loss. It has been reported that normal hearing is rare in patients with severe inner ear vestibular malformations. A 9-year-old boy had had complained of recurrent dizziness and disequilibrium for 2 months. Clinical and neuro-otological examinations showed peripheral involvement of the vestibular system, while audiological investigation was normal. High-resolution magnetic resonance imaging, with three-dimensional reconstruction, showed dysplasia of the bilateral lateral semicircular canals (LSCCs). Isolated vestibular malformation might not be as rare as previously thought, and should be examined by imaging of the temporal bone.

    We report two children who survived neurologic injury (near-drowning and Reye's syndrome) and adult respiratory distress syndrome and who required prolonged ventilatory support. Follow-up examination in both children showed steady neurologic recovery, but five months following discharge from their acute illness, profound hearing loss was diagnosed in both children. A review of the literature is reported and the hypothesis that combined aminoglycoside antibiotic and loop diuretic therapy caused the hearing loss is presented. Recommendation is made for audiologic assessment within six months of recovery from critical illness of pediatric patients in whom therapy has included loop diuretic and aminoglycoside antibiotic therapy.

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

    1994-08-01

    This study compared 50 patients presenting to an otolaryngology clinic with a complaint of dizziness and 50 patients presenting with hearing loss on questionnaire measures of panic, phobic avoidance, generalized anxiety, and depression. Clinical and laboratory evaluations of vestibular and audiological complaints were also completed. Twenty percent of the group with dizziness and none of the group with hearing loss reported symptoms that met DSM-III-R criteria for panic disorder. Patients with dizziness and peripheral vestibulopathy had more symptoms of phobic avoidance, generalized anxiety, and depression than patients with confirmed hearing loss.

    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.

    2009-10-01

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

    2013-10-07

    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.

    2014-01-01

    Full Text Available A twenty-eight-year-old woman with an eight-year history of partial hearing loss presented with a two-year history of worsening deafness and new-onset seizures. Evaluations of tympanic membranes, cochlea, and auditory brain stem reflexes demonstrated no physiologic basis for deafness. Video-EEG monitoring demonstrated that the patient responded normally to spontaneous auditory stimuli and that typical spells were nonepileptic in origin. Although pseudohypacusis is reported in audiology literature, and psychogenic nonepileptic spells are well-studied phenomena in neurology literature, the present case is an unusual case of dual psychogenic symptoms, a relationship that indicates poorer prognosis.

    Not being able to hear can present significant challenges for the therapist and for the deaf therapist/hearing client dyad. It can also create opportunities. Although the literature indicates that most culturally Deaf therapists work with Deaf clients due to their mutual use of American Sign Language, I describe (a) the background of an audiologically deaf therapist who relies on speech reading rather than sign language, and (b) this therapist's clinical work with hearing clients. Some of the relational dynamics of these treatments are identified, and I conclude by noting how attention to communication can benefit the work of all psychotherapists.

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

    Directory of Open Access Journals (Sweden)

    Irene Olaussen

    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.

    SUMMARY A retrospective chart review was used for 31 patients with sudden, progressive or fluctuating sensorineural hearing loss (SHL) in the only hearing ear who had been consecutively evaluated at the ENT, Audiology and Phoniatrics Unit of the University of Pisa. The group of patients was evaluated with a complete history review, clinical evaluation, imaging exam (MRI, CT), audiologic tests (tone and speech audiometry, tympanometry, study of stapedial reflexes, ABR and otoacoustic emission) evaluation. In order to exclude genetic causes, patients were screened for CX 26 and CX30 mutations and for mitochondrial DNA mutation A1555G. Patients with sudden or rapidly progressive SHL in the only hearing ear were treated with osmotic diuretics and corticosteroids. In patients who did not respond to intravenous therapy we performed intratympanic injections of corticosteroid. Hearing aids were fitted when indicated and patients who developed severe to profound SHL were scheduled for cochlear implant surgery. The aim of this study is to report and discuss the epidemiology, aetiopathogenesis, therapy and clinical characteristic of patients affected by SHL in the only hearing hear and to discuss the issues related to the cochlear implant procedure in some of these patients, with regard to indications, choice of the ear to implant and results.

  11. Relationship between Otolaryngologic Complaints and Systemic Comorbidities Observed in a Group of Hearing Aid Users

    Directory of Open Access Journals (Sweden)

    Ribas, Angela

    2014-11-01

    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.

    2012-01-01

    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.

    2016-03-01

    Full Text Available Introduction The cervical spine is a flexible link between the sensory platform of the skull and torso. The fundamental principle of its operation is due to the balance between muscle strength and flexibility, and any dysfunction of this balance causes neck pain, known as cervicalgia. Objective The objective of this study is to analyze the most prevalent neurotological findings in adults with neck pain. Method A cross-sectional study in which 33 adults from 50 to 83 years of age with neck pain were evaluated and underwent the following procedures: anamnesis, as well as ENT, audiological, and vestibular exams. Results The most evident neurotological symptoms were dizziness (75.7%, tinnitus, neck cracking, tingling in the extremities, and auditory problems (36.3% for each. The most frequently reported clinical symptoms were related to cardiovascular (69.7%, endocrine-metabolic (48.5%, and rheumatic (30.3% systems. In the audiological assessment, 30 subjects (91.0% presented hearing impairment in at least one ear, with sensorineural impairment being the most prevalent (88.0%. In the vestibular assessment, there were alterations in 13 subjects (39.0% found in the caloric test. There was a prevalence of alterations in the peripheral vestibular system with a predominance of irritative peripheral vestibular dysfunction. Conclusion Neurotological complaints were frequent in this population, verifying the importance of these tests in the dysfunctions of the cervical region or the craniocervical junction.

    Recently, Zenner et al. implanted the first totally implantable electronic hearing devices in patients with SNHL (HNO 46 [1998] 844-852). In the present report, technical and audiological features of the implant TICA are published. The development of the piezoelectric transducer and the microphone for implantation in the posterior wall of the auditory canal as components for the present fully implantable hearing system has already been described (HNO 45, 1997, 792-880). Here we report about our experience with the electronic main module that completes the TICA LZ 3001 system. This module is suited for implantation in the mastoid bone and contains the signal-processing electronics and an integrated battery that can be recharged transcutaneously with a portable charger. The recharging time is around 2 h for an implant operating time of 50 h. The microphone and transducer connectors allow for easy replacement of the main module when the battery lifetime is reached. This lifetime is around 3-5 years. A small wireless remote control allows volume adjustment, contains an on/off switch, and permits selection of four different individual hearing programs. The basic audiological features are provided by a flexible, digitally programmable 3-channel-AGC-system with a peak clipping function. The total bandwidth is around 10 kHz. To our knowledge this is the first fully implantable hearing system that has been in implanted in humans.

    A retrospective study was performed on patients who underwent myringoplasty for either anterior or subtotal perforations over an 8-year period (from 1994 till 2004). We used the KTP-laser assisted anterior anchoring technique combining with anterior "pull-back" method. Patients' ages ranged from 6-62 years (median 36.5). The mean follow-up period was 2.8 years (minimum 6 months). The audiological results were analysed with the "Pytel software", which was developed in our department. As for the procedure, the drum remnant was freed from the malleus handle with the use of the laser and elevated out of it's sulcus anterior-superiorly. Large fascia graft was fashioned with a split of 4-5 mm in the middle of one edge. The graft was placed using the underlay technique medial to the handle of the malleus. A pull-back tunnel was created at the border of the anterior quadrants to further facilitate the survival of the graft. In this series the graft taking rate was 100%. Reperforation due to an undersized fascia was observed in one case. Post-operative audiological results indicated no bone conduction threshold elevation in any frequencies. Using the laser, cochlear trauma can be prevented, double fixation of the drum prevents lateralisation and blunting. Wide canalplasty makes both the approach and the follow-up very easy. Thorough soft tissue and bone work is advantageous from the fascia taking rate point of view.

    The aim of this study was to compare anatomic and audiological results of cartilage graft with temporal fascia graft in type 1 tympanoplasty patients with low middle ear risk index (MERI). In this retrospective study, 63 patients that underwent type 1 tympanoplasty with chondroperichondrial island graft between July 2009 and November 2010 were compared with 45 patients in whom temporal muscle fascia was used. Patients in both groups had low MERI values varying between 1 and 3. Five and nine patients underwent masteidectomy in cartilage and fascia group, respectively. Mean duration of follow-up was 11.9 ± 3.7 (5-17) months. Mean value was calculated at pre-operative and post-operative hearing threshold 0.5, 1, 2, 4 kHz, and air bone gap (ABG) gain was compared in both cartilage and fascia groups. when pre-operative and post-operative ABG gain were compared, significant decrease was seen in ABG levels (p fascia group. In both groups, age, sex, and the addition of mastoidectomy procedure had no significant effect on ABG gain and success. Cartilage is a graft material that may be preferred without concern about the effects on hearing results, especially, in patients with low MERI values. The addition of mastoidectomy had no impact on the outcome of operation and audiological results. However, further studies with larger case series may be carried out to further clarify the issue.

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

    Directory of Open Access Journals (Sweden)

    Dorothea Wendt

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

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.

    Full Text Available The study exposed performance level of special children and Medical Diagnosis and Therapeutic Related Services of SPED schools in Isabela province, Northern Philippines such as Medical /Diagnostic and Evaluative services, Audiology services, Psychological services, Occupational Therapy, Physical Therapy and Speech-Language Pathology. Null hypothesis of no significant difference on assessment was tested at 0.05 level of significance. Randomly selected respondents were 19 SPED teachers and 80 parents. SPED teachers and parents of special children from one private and two government SPED institutions were the target groups of the research study. Experts validated the data gathering tool, being translated in local languages. Statistical tools include Percentage, and Weighted Mean. Respondents rated said services as “satisfactorily attained”, denoted by the Overall Composite Means 3.32 and 2.97, respectively. Null hypothesis was rejected on audiology, occupational therapy, psychological, and speech-language pathology; but was accepted on physical therapy, and medical/diagnostic and evaluative services. In contrast, parents’ appraisal signified significance of said related services to functioning of subject children. To benefit from Special Education, recommended is continues availability of improved services based on Individualized Educational Program of each child. School Board should advocate SPED related services for special children for them to benefit from Special Education Program.

    2011-03-01

    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.

    Full Text Available Introduction: The implantable prosthesis of osseous conduction (BAHA is deemed to be an excellent option in the auditory rehabilitation of patients with conductive and mixed hearing loss, unilaterally or bilaterally, and unilateral sensorineural hearing loss. It has been a good advantage over the conservative bone conduction apparatus and those of individual sound-amplifier apparatus (ISAA, when their usage becomes unfeasible because of chronic otitis externa, which has a hard clinic control. Objective: To introduce the first BAHA case performed in Brazil, as duly authorized by ANVISA (National Agency for Sanitary Surveillance, to rehabilitate the mixed hearing loss with occurrences of chronic otitis externa. Method: 50-year-old female patient with right-ear moderate and left-ear severe hearing loss, bilateral tinnitus derived from otosclerosis, was submitted to 04 surgeries of stapedotomy and unable to use ISAA as a result of otorrhea and bilateral otalgia. The medical and audiological evaluation indicated the benefit of using BAHA. Having surgery been performed and BAHA implemented, the patient showed a significant improvement in audiometric thresholds, speech perception and distinction, as well as she declared to be extremely satisfied with the esthetic factor. Final commentaries: BAHA surgical process is safe, simple and swift, thus providing excellent audiological results and a higher degree of satisfaction to patients.

The otolaryngological findings include hearing loss, otorrhea, recurrent otitis, hypertrophy of tonsils and adenoid, recurrent rhinosinusitis, speech disorders, snoring, oral breathing and nasal obstruction. OBJECTIVE: To evaluate the impact of enzymatic replacement therapy with laronidase (Aldurazyme(r in patients with mucopolysaccharidosis (MPS I, regarding sleep and hearing disorders, and clinical manifestations in the upper respiratory tract (URT. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

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

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

    Over the last decade, bone conducting hearing aids, cochlear implants and implantable hearing aids have come to represent additional treatment options in clinical routine-alongside conventional hearing aids-for hearing impaired patients. Thanks to experience gained in recent years with implantable hearing aids and the consistent evaluation of functional results, the original spectrum of indications has been progressively extended. Today, implantable hearing aids are available for the hearing (re)habilitation of various forms of middle ear pathology as well as sensorineural hearing loss within the audiological criteria. With CE certification for children, the treatment of younger patients with implantable hearing aids has also become possible. Using the Vibrant Soundbridge as an example, the function, indications and contraindications of implantable hearing aids are described and the surgical procedure and post-operative care discussed.

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

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

    Sensorineural hearing loss in elderly patients (presbycusis) relatively often coexists with annoying tinnitus (termed presbytinnitus [PT] by Claussen). The purpose of this study was to verify the conditions of improvement in patients treated for PT. We fitted with hearing aids 33 PT patients (ages 60-89 years) and questioned them about subjective hearing results. Assessment tools included comprehensive audiology and a subjective self-assessment survey of tinnitus characteristics. All patients had very good tolerance of the hearing aids; 28 reported that they had considerable reduction in PT intensity. Fitting PT patients with hearing aids is usually effective. In patients with unilateral sensorineural hearing loss and tinnitus, fitting the impaired ear is sufficient. Individuals with bilateral complaints require bilateral fitting. Effectiveness of fitting in the affected group of patients depended on speech discrimination scores before fitting. The improvement scores were higher in patients with more aggravated symptoms and did not depend on history of prolonged exposure to excessive noise.

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.

    This report outlines the teamwork learning outcomes of an interprofessional workshop conducted with a cohort of 81 graduate-entry students of occupational therapy, physiotherapy, speech pathology, and audiology. This four-hour workshop was based around a case scenario of a child with developmental coordination disorder. This report describes and evaluates the development of knowledge and skills of teamwork that were facilitated through this workshop. Students completed questionnaires before and after the workshop about their knowledge of teamwork, requisites for working together, the utility of the workshop, and learning outcomes. The evaluation indicated that the workshop was successful from the students' perspectives in confirming the importance of teamwork and the processes of communication and collaborative goal setting. Students refined their own professional roles and developed an appreciation of the contribution of other professions and parents. This recognition of the comparative value of different professional contributions in providing holistic patient care is one of the starting points for education about interprofessional teamwork.

    Many methods of screening for hearing impairment are available. The aim of our study was to determine which ones were really used in 1992. At the request of the British Audiology Society, we conducted an inquiry into the organization of screening for deafness in neonates and infants in Europe. In practice all 6-9 month-old infants are tested with behavioural tests in every country. For the neonates, generally only those at risk for hearing-impairment (about 5%) were tested. The most widely used tests were behavioural ones. Only specialized centers used transient evoked otoacoustic emissions (TEOAEs). This last test assesses the active mechanical properties of the cochlea and allows detection of even mild or unilateral sensorineural deafness.

    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.

    Hundreds of syndromes may be associated with hearing impairment. Within recent years, there has been heightened research and clinical interest in hearing and syndromes, probably due to both advances in molecular genetics and improved techniques for auditory assessment of infants and young children. An example of the current appreciation for the possible relation between auditory dysfunction and syndromes or patterns of malformations is the inclusion of syndromes as a risk factor for hearing impairment by the 1990 Joint Committee on Infant Hearing. In this paper, we review syndromes and patterns of malformation that are frequently or occasionally associated with hearing impairment. In addition, we illustrate, in case studies, auditory findings that may be associated with three of these syndromes and patterns of malformation: Carpenter syndrome, ichthyosiform dermatosis, and Townes syndrome. We conclude with a discussion of strategies for audiologic assessment and management of infants and children with syndromes and patterns of malformations.

    Upon review of the statutory health insurance reimbursement guidelines, a specific quality assurance questionnaire concerned with the provision of hearing aids was introduced that assesses elements of patient satisfaction within Germany's public healthcare system. APHAB questionnaire-based patient evaluation of the benefit of hearing aids represents the third pillar of audiological diagnostics, alongside classical pure-tone and speech audiometry. Another new aspect of the national guidelines is inclusion of free-field measurements in noise with and without hearing aids. Part 2 of this review describes new diagnostic aspects of speech audiometry. In addition to adaptive speech audiometry, a proposed method for applying the gold standard of speech audiometry - the Freiburg monosyllabic speech test - in noise is described. Finally, the quality assurance questionnaire will be explained as an appendix to template 15 of the regulations governing hearing aids.

    1988-12-01

    To obtain basic data for evaluating the hearing handicaps experienced by workers with noise-induced hearing loss, the ability to distinguish monosyllables was examined by speech audiometry. The percentage of correct scores for each monosyllable varied widely in 88 male workers, depending on the presentation level and the severity of hearing loss. A 67-S word list (prepared by the Japan Audiological Society), consisting of 20 Japanese monosyllables (17 consonant-vowel (CV) syllables and three vowel syllables), was used to evaluate consonant and vowel confusion at the level of 20 to 90 dB ( re HL at 1000 Hz [9]). Regarding the confusion among five subsequent vowel nuclei, we observed particular confusion patterns resulting from the similarity of the first formant (F1). Analysis of the tendency toward confusion among individual monosyllables together with the audiometric configuration will provide useful information for evaluating noise-induced hearing loss.

    Sudden sensorineural hearing loss (SSNHL) is commonly encountered in audiologic and otolaryngologic practice. SSNHL is most commonly defined as sensorineural hearing loss of 30 dB or greater over at least three contiguous audiometric frequencies occurring within a 72-hr period. Although the differential for SSNHL is vast, for the majority of patients an etiologic factor is not identified. Treatment for SSNHL of known etiology is directed toward that agent, with poor hearing outcomes characteristic for discoverable etiologies that cause inner ear hair cell loss. Steroid therapy is the current mainstay of treatment of idiopathic SSNHL in the United States. The prognosis for hearing recovery for idiopathic SSNHL is dependent on a number of factors including the severity of hearing loss, age, presence of vertigo, and shape of the audiogram.

    Full Text Available Deficits in central auditory processing may occur in a variety of clinical conditions including traumatic brain injury, neurodegenerative disease, auditory neuropathy/dyssynchrony syndrome, neurological disorders associated with aging, and aphasia. Deficits in central auditory processing of a more subtle nature have also been studied extensively in neurodevelopmental disorders in children with learning disabilities, ADD, and developmental language disorders. Illustrative cases are reviewed demonstrating the use of an audiological test battery in patients with auditory neuropathy/dyssynchrony syndrome, bilateral lesions to the inferior colliculi, and bilateral lesions to the temporal lobes. Electrophysiological tests of auditory function were utilized to define the locus of dysfunction at neural levels ranging from the auditory nerve, midbrain, and cortical levels.

    In order to develop a sensitive audiometric protocol for identifying ototoxicity in children, a retrospective study of 16 children treated with cisplatin and/or carboplatin was performed. Audiometric testing was done by means of pure-tone threshold audiometry (PTA), high-frequency audiometry (HFA), and distortion product otoacoustic emissions (DPOAEs). Cisplatin caused a sensorineural high-frequency hearing loss in the study group compared to the controls (p cisplatin patients had a grade 2 or 3 ototoxicity. However, ototoxicity was not found in the patients treated with carboplatin. An excellent correlation was found between DPOAE levels and results obtained by audiometry (r = 0.82). Patients exposed to cisplatin are at significant risk for the development of drug-induced sensorineural hearing loss. Because of the several advantages of DPOAEs (noninvasive, objective, rapid, easy to use, sensitive) this method should be added in the audiological follow-up in infants and toddlers.

Methods: A retrospective review of medical records from 470 consecutive patients who visited a tertiary care hospital for evaluation of chronic subjective tinnitus between January 2009 and June 2010 was performed. Patients were divided into three subgroups based on age. Clinical, audiological, and psychological characteristics of each subgroup were analyzed. Results: Of the 470 patients evaluated, 85 were less than 40, 217 between 40 and 60, and 168 above 60 years of age. Most patients were men and complained of unilateral, acute high-pitched tinnitus. Most patients above the age of 40 years complained of loud and annoying tinnitus and had worse stress and severity scores. Conclusions: Chronic tinnitus in older adults is subjectively louder, more annoying, and more distressing than that found in younger patients. We recommend considering age in the patient management plan.

    Among objective audiologic tests, the most important were tests of brain stem auditory evoked potentials. The objective of the study was to test the configuration, degree of hearing loss, and response characteristics of auditory brain stem evoked potentials in children with hearing loss occurred due to infectious disease. A case control study design was used. The study group consisted of 54 patients referred for a hearing test because of infectious diseases caused by other agents or that occurred as congenital infection. Infectious agents have led to the emergence of various forms of sensorineural hearing loss. We have found deviations from the normal values of absolute and interwave latencies in some children in our group. We found that in the group of children who had the diseases such as purulent meningitis, or were born with rubella virus and cytomegalovirus infection, a retrocochlear damage was present in children with and without cochlear damage.

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

    Ninety infants and children were prospectively randomized to receive cefepime (n = 43) or cefotaxime (n = 47) for therapy of bacterial meningitis. The two treatment groups were comparable in terms of age, duration of illness before enrollment, history of seizures, clinical status on admission, and etiology. Six (7%) patients died--two treated with cefepime and four treated with cefotaxime. Clinical response, cerebrospinal fluid sterilization, development of complications, antibiotic toxicity, and hospital stay were similar for the two treatment regimens. Concentrations of cefepime in cerebrospinal fluid varied from 55 to 95 times greater than the maximal MIC required by the causative pathogens. Audiologic and/or neurologic sequelae were found in 16% of the cefepime-treated patients and 15% of the cefotaxime-treated patients examined 2 to 6 months after discharge. We conclude that cefepime is safe and therapeutically equivalent to cefotaxime for management of bacterial meningitis in infants and children.

    2009-10-01

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

    Full Text Available Infections of central nervous system are still a major problem. Despite the introduction of newer antimicrobial agents, mortality and long-term sequelace associated with these infections is unacceptably high. Based on the evidence that proinflammtory cytokines have a role in pathophysiology of bacterial and tuberculous meningitis, corticosteroids with a potent anti-inflammatory and immunomodulating effect have been tested and found to be of use in experimental and clinical studies, Review of the available literature suggests steroid administration just prior to antimicrobial therapy is effective in decreasing audiologic and neurologic sequelae in childern with H. influenzae nenigitis. Steroid use for bacterial meningitis in adults is found to be beneficial in case of S. pneumoniae. The value of adjunctive steroid therapy for other bacterial causes of meningitis remains unproven. Corticocorticoids are found to be of no benefit in viral meningitis, Role of steroids in HIV positive patients needs to be studied.

    Full Text Available Chronic inflammation of the middle ear is the most frequent cause of otogenic complications. Meningitis is the most frequent intracranial complications, followed by otogenic brain abscess in neglected otitis media. Although temporal lobe abscesses are more common than cerebellar abscesses, the converse was found to be true in our series of 17 cases. 16 cases of cerebellar abscess and 1 case of temporal lobe abscess were reported as a complication of chronic otitis media (COM. In our group of patients, otogenic brain abscesses were more frequent in male patients of age group 5–20 years with mean age of 14 years. Diagnostic procedure included history, clinical, otorhinolaryngological examination, audiological, microbiological, neurological, ophthalmological, and radiological examinations. The treatment included primary neurosurgical approach (abscess drainage followed by radical otosurgical treatment.

    The majority of patients with moderate to severe hearing loss can be supplied with conventional hearing aids depending on severity and cause for hearing loss in a satisfying way. However, some patients either do not benefit enough from conventional hearing aids or cannot wear them due to inflammatory reactions and chronic infections of the external auditory canal or due to anatomical reasons. For these patients there are fully- and semi-implantable middle ear and bone conduction implants available. These devices either directly stimulate the skull (bone conduction devices), middle ear structures (active middle ear implants) or the cochlea itself (direct acoustic stimulation). Patients who failed surgical hearing rehabilitation or do not benefit from conventional hearing aids may achieve a significant better speech understanding and tremendous improvement in quality of life by implantable hearing devices with careful attention to the audiological and anatomical indication criteria.

    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.

    Full Text Available The objective of this study was to evaluate the association between rest heart rate (HR and the components of the auditory evoked-related potentials (ERPs at rest in women. We investigated 21 healthy female university students between 18 and 24 years old. We performed complete audiological evaluation and measurement of heart rate for 10 minutes at rest (heart rate monitor Polar RS800CX and performed ERPs analysis (discrepancy in frequency and duration. There was a moderate negative correlation of the N1 and P3a with rest HR and a strong positive correlation of the P2 and N2 components with rest HR. Larger components of the ERP are associated with higher rest HR.

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

    A better understanding of how the human auditory system represents and analyzes sounds and how hearing impairment affects such processing is of great interest for researchers in the fields of auditory neuroscience, audiology, and speech communication as well as for applications in hearing......-instrument and speech technology. In this thesis, the primary focus was on the development and evaluation of a computational model of human auditory signal-processing and perception. The model was initially designed to simulate the normal-hearing auditory system with particular focus on the nonlinear processing...... aimed at experimentally characterizing the effects of cochlear damage on listeners' auditory processing, in terms of sensitivity loss and reduced temporal and spectral resolution. The results showed that listeners with comparable audiograms can have very different estimated cochlear input...

    2002-01-01

    Pallister-Killian syndrome is a rare disorder characterised by a specific combination of anatomic anomalies, mental retardation and lack of speech acquisition due to tetrasomy 12p. Hearing loss does not seem to be characteristic for this syndrome, although it was reported in several cases. We present the case of a girl first seen in our department at the age of 6 months. A severe sensory hearing loss was confirmed by subjective and objective audiometry. The child was successfully equipped with hearing aids. In the literature almost all children with Pallister-Killian syndrome are described as not developing verbal speech. Surprisingly their hearing abilities were not examined systematically. We advise audiological testing of children with Pallister-Killian syndrome.

    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.

    2014-11-01

    Children diagnosed with autism spectrum disorder (ASD) are often referred for audiological diagnostic evaluation. This article provides some strategies for preparing children for a successful diagnostic evaluation. Children who are deaf or hard of hearing with a dual diagnosis of ASD may have difficulty learning to demonstrate detection or imitation of the Ling 6 sounds. The Ling 6 sounds are used to determine what a child with a dual diagnosis can hear and discriminate with amplification (hearing aids or cochlear implants). Because children with ASD may not look at the conversational partner and may have difficulty with imitation, adaptive strategies may be necessary to teach these children with dual diagnosis their first words. Strategies for teaching children with dual diagnosis through sign language will also be discussed.

  8. Application of transient evoked otoacoustic emissions to pediatric populations.

    Science.gov (United States)

    Norton, S J

    1993-02-01

    Transient evoked otoacoustic emissions (TEOAEs) occur after presentation of brief acoustic stimuli such as clicks and tone pips. They represent physiological activity from within the cochlea, specifically from normal functioning outer hair cells. TEOAEs are frequency specific in that their spectra are determined by the spectra of the evoking stimulus and the audiometric configuration. TEOAEs are sensitive to mild to moderate degrees of cochlear hearing loss up to about 40 to 50 dB HL. They can be measured rapidly and noninvasively in infants and children. Among the potential applications in pediatric audiology are screening for hearing impairment in neonates, separating peripheral hearing loss and central auditory dysfunction, and monitoring cochlear status in children receiving ototoxic drugs.

    Speech-Language Therapy and Audiology graduates have worked in community service for 6 years. An evaluation of the impact of this strategy is now seen as important. In this discussion paper we report on the content and process of feedback sessions with 132 graduates from the University of the Witwatersrand during their community service placements from 2003-2008. Experiences and perceptions of these graduates are discussed in relation to a model as well as in relation to additional research conducted with our profession and other community service professions. Themes discussed include professional and technical issues, systemic and managerial issues, interpersonal issues and ethical issues. Perceptions on the adequacy of training are also described. The overall goals of community service are considered as well as indices for measuring success. Implications are considered for training institutions, for the Department of Health and for the profession.

  10. How can speech-language therapists and audiologists enhance language and literacy outcomes in South Africa? (And why we urgently need to

    2011-12-01

    Full Text Available Basic education in South Africa faces a crisis as learners fail to achieve the necessary outcomes in the related areas of language and literacy. The aims of this paper are twofold. Firstly, we aim to describe and discuss the education crisis by outlining the educational landscape, relevant policy imperatives and implementation challenges in post-apartheid education. The systemic factors contributing to the literacy crisis are emphasised. Secondly, we argue that speech language therapists and audiologists (SLTAs have a role to play in supporting basic education in South Africa through developing language and literacy. It is suggested that the professions of speech-language pathology and audiology must be socially responsive and population-focused in order to make meaningful contributions to development in South Africa. The potential roles of SLTAs are discussed with suggestions for further actions required by the professions to enable a contextually relevant practice in a resource-constrained environment.

  11. How well can centenarians hear?

    Directory of Open Access Journals (Sweden)

    Zhongping Mao

    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.

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

    Full Text Available Background: Diabetes mellitus (DM is commonly metabolic disorders of carbohydrate in which blood glucose levels are abnormally high due to relative or absolute insulin deficiency. In addition, it is characterized by abnormal metabolism of fat, protein resulting from insulin deficit or insulin action, or both. There are two broad categories of DM are designated as type 1 and type 2. Type 2 diabetes is due to predominantly insulin resistance with relative insulin deficiency noninsulin-dependent DM. Type 2 diabetes is much more common than insulin-dependent DM. Objectives: The aim of this study was to assess, if there is any abnormality in neural conduction in auditory brain-stem pathway in type 2 DM patients having normal hearing sensitivity when compared to age-matched healthy populations. Materials and Methods: This study included middle - aged 25 subjects having normal hearing with diabetes type 2 mellitus. All were submitted to the full audiological history taking, otological examination, basic audiological evaluation and auditory brain-stem response audiometry which was recorded in both ears, followed by calculation of the absolute latencies of wave I, III and V, as well as interpeak latencies I-III, III-V, I-V. Results: Type 2 DM patients showed significant prolonged absolute latencies of I, III (P = 0.001 and interpeak latencies I-III, III-V and I-V in left ear (P = 0.001 and absolute latencies of I, V (P = 0.001, interpeak latencies III-V was statistically significant in right ear. Conclusions: The prolonged absolute latencies and interpeak latencies suggests abnormal neural firing synchronization or in the transmission in the auditory pathways in normal hearing type 2 diabetes mellitus patients.

    In this study, the authors report the results of a three-stage newborn hearing screening (NHS) program for well babies at the Gazi University Hospital (GUH) in Ankara between 2003 and 2013. GUH-NHS was performed by automated transient evoked otoacoustic emission (a-TEOAE) at the first and second steps and by automated brainstem audiometry (a-ABR) at the third step. The data were analysed to assess not only rate of congenital permanent hearing loss (CPHL), but also the effectiveness of the program during the years. A total of 18,470 well babies were tested. The data showed that coverage ratio for the GUH-born babies was increased and more outside-born babies (OBB) were admitted by time (means 84.31 and 11.28 %, respectively). Mean CPHL was found to be 0.26 %. Mean referral rate was decreased to 0.81 % by a-ABR from 2.16 % by a-TEOAE. Mean of missed cases in any stage of GUH-NHS was 4.88 %. It was seen that neither CPHL nor referral rate, but only ratio of missed ones presented increase in parallel to increment in OBB. This paper first presents that clinically acceptable screening procedures developed in GUH by time, and secondly higher rate of CPHL in Turkey than in the Western countries, and benefits of third stage screening by a-ABR because it prevented referral of 251 children (1.29 %) to the clinical tests. We think that this number is reasonably important regarding not only economical point of view, but also waiting lists in the audiology departments in a developing country, in which audiological service is still limited.

  15. Self-Fitting Hearing Aids: Status Quo and Future Predictions.

    Keidser, Gitte; Convery, Elizabeth

    2016-04-12

    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.

    2012-10-01

    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.

    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.

    Full Text Available ObjectivesRheumatoid arthritis (RA is well known to affect many different organ systems. Previous work suggests that this includes the auditory system.The objectives of this work are to evaluate the pattern of hearing impairment in patients with rheumatoid arthritis and also to examine the possible associations between hearing impairment and related RA features especially disease activity.Materials and methodsThirty RA patients (mean age of 44.5 ± 9.9 years; female sex (90% and 17 healthy controls (mean age of 41.5±9.1 years; female sex (76.4% were included in our study. The 2 groups were matched for age and sex (p>0.05. Otoscopic examination was normal in all participants.No subject of the 2 groups has had any abnormalities at otoscopic examination. Hearing impairment was evaluated by pure tone audiometry and tympanometry including the static compliance, middle ear pressure, stapedial reflex threshold test. In all patients the clinical features, laboratory data, X-rays, disease activity index-DAS 28 were performed.ResultsHearing loss was more prevalent in RA patients compared to healthy controls (56.7 vs 11.8%; p=0.005. RA patients have conductive, sensorineural and mixed hearing loss in respectively 43.4, 3.3 and 10 % of cases. Association analysis between hearing characteristics and remission in RA patients shows that RA patients in remission have significantly lower mean hearing thresholds (12.8±5.2dB vs 18.8±6.9 dB ; p=0.04.ConclusionThis study suggests that hearing loss risk is higher in RA patients and seems to be associated to disease duration. Hearing loss in RA was directly proportional to the disease activity index-DAS 28. Audiological evaluation must be performed periodically to identify possible audiological damage.

    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.

    Otologic-audiologic examination was carried out in 75 patients (between 42 and 86 years of age; average age: 65 years) with confirmed internal angiologic obliteration of the carotid artery, either unilateral or bilateral. There were 51 unilateral and 24 bilateral stenoses/occlusions. Diseases of the ear were excluded clinically and audiologically. - The mean hearing loss shows a sensorineural high tone loss in the tone audiogram. The range of scatter of high tone loss increases proportionally to the increase of frequency. - Compared with the physiological examination of geriatric patients, the total word comprehension and especially the minimal discrimination loss point towards a pathologic impairment of hearing. The total word comprehension amounts to 250.79% in the 51-60 age group, 237.79% in the 61-70 age group, 175.83% in persons aged 71-80 years, and 118.33% for those over 80 years of age. The minimal discrimination loss comprises 5.83% in the 51-60 age group, 9.79% in the 61-70 age group, 22.50% in patients between 71 and 80 years, and 48.00% in those over 80 years. - No connection between the extent of loss of hearing and the stage of obliteration of the carotid artery can be shown. However, the decompensation of total word comprehension and especially the minimal discrimination loss is a very important sign. - These findings contribute towards a differentiation of physiologic and pathologic hearing diseases in old age with particulas reference to the underlying arteriosclerotic disease.

    Objectives: Auditory neuropathy (AN) is a sensorineural hearing disorder characterized by absent or abnormal auditory brainstem responses (ABRs) and normal cochlear outer hair cell function as measured by otoacoustic emissions (OAEs). Many risk factors are thought to be involved in its etiology and pathophysiology. Three Chinese pedigrees with familial AN are presented herein to demonstrate involvement of genetic factors in AN etiology. Methods: Probands of the above - mentioned pedigrees, who had been diagnosed with AN, were evaluated and followed up in the Department of Otolaryngology Head and Neck Surgery, China PLA General Hospital. Their family members were studied and the pedigree diagrams were established. History of illness, physical examination,pure tone audiometry, acoustic reflex, ABRs and transient evoked and distortion- product otoacoustic emissions (TEOAEs and DPOAEs) were obtained from members of these families. DPOAE changes under the influence of contralateral sound stimuli were observed by presenting a set of continuous white noise to the non - recording ear to exam the function of auditory efferent system. Some subjects received vestibular caloric test, computed tomography (CT)scan of the temporal bone and electrocardiography (ECG) to exclude other possible neuropathy disorders. Results: In most affected subjects, hearing loss of various degrees and speech discrimination difficulties started at 10 to16 years of age. Their audiological evaluation showed absence of acoustic reflex and ABRs. As expected in AN, these subjects exhibited near normal cochlear outer hair cell function as shown in TEOAE & DPOAE recordings. Pure- tone audiometry revealed hearing loss ranging from mild to severe in these patients. Autosomal recessive inheritance patterns were observed in the three families. In Pedigree Ⅰ and Ⅱ, two affected brothers were found respectively, while in pedigree Ⅲ, 2 sisters were affected. All the patients were otherwise normal without

    Full Text Available BACKGROUND: Sudden sensorineural hearing loss (SSNHL is a perplexing condition for patients and there are many controversies about its etiology, audiologic characteristics, prognostic factors, and treatment. METHODS: In this prospective study, we performed some audiologic tests, including PTA, IA, ABR, and OAE (TEOAE before beginning treatment of 53 patients with SSNHL. We assigned the patients randomly to two treatment groups: oral steroids + acyclovir vs. intravenous urographin. Twenty-eight patients underwent Magnetic Resonance Imaging (MRI of the Brain. RESULTS: Of 53 patients (22 female and 31 male, 22 (41.5% had negative or no signal to noise ratio and overall correlation in TEOAE. Twenty-six patients (49% had positive overall correlations less than 50%, and 5 patients (4.4% had overall correlations >50%. Fifteen patients (28. 3% responded completely or well, 20 (37.7% responded partially, and 18 (33.9% had poor or no response to the treatment. The mean values for overall correlation in 3 subgroups of patients (no response, partial response, and complete response were – 3. 5% (+ 1/16%, +11% (+ 1/99%, and +36.6% (+3/07%, respectively (P = 0.01. Twenty out of 52 patients had no reproducible wave in ABR (38.5%, and waves I, III, and V were absent in 40 (77%, 31 (59.6% and 21 (40% patients, respectively. There were some limitations (false positive and false negative results in ABR use in our cases, but it may be useful in detecting site of lesion in SSNHL. Overall, according to the results of OAE, ABR, and brain MRI of these patients, 3 were affected by acoustic neurinomas, at least 1 had auditory neuropathy, and the site of lesion was cochlear in 6, and cochlear + retrocochlear in 13 patients. CONCLUSIONS: ABR has limitations for use in SSNHL and seems not to obviate the need for brain MRI, but may help in determining the site of lesions such as ischemia or neuropathy. Overall correlation (and S/N ratio in TEOAE is a valuable

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

O avanço tecnológico tem disponibilizado inúmeros recursos para realizar o monitoramento da audição, porém, apesar da disponibilização de protocolos de avaliação internacionais, existem controvérsias quanto à escolha do procedimento de maior sensibilidade e especificidade para este fim. OBJETIVO: Analisar os procedimentos audiológicos utilizados no monitoramento auditivo dos indivíduos expostos à medicação ototóxica. METODOLOGIA: Realizou-se busca eletrônica nas bases de dados MEDLINE e LILACS, a partir da combinação entre os descritores que caracterizaram as temáticas monitoramento auditivo, ototoxicidade e câncer. A literatura apontou dois principais procedimentos efetivos no monitoramento: a audiometria de altas freqüências e as emissões otoacústicas. Ambos permitem que a alteração no sistema auditivo seja identificada antes que haja um comprometimento dos limiares tonais na faixa de freqüências convencional, e conseqüentemente na habilidade de compreensão da fala. CONCLUSÃO: O protocolo de monitoramento auditivo foi sugerido considerando a capacidade do paciente em responder aos testes comportamentais e a etapa do monitoramento (primeira avaliação ou subseqüentes. No caso de portadores de câncer, o monitoramento auditivo deve ser disponibilizado no local de tratamento do indivíduo.Some pharmaceutical products are capable of damaging the human auditory system.

    Objective Clinical characteristics of deaf patients caused by mitochondrial DNA (mtDNA) 1555 /1494 mutations are not clearly defined. Here we review the relative literature to summarize the audiological characteristics of these patients and to discuss the factors affecting hearing loss degree.Methods We have selected “mtDNA 1555/1494 mutation” and “sensorineural hearing loss” as keywords to search for the data in the databases of CNKI , WanFang, VIP, and PubMed. From the resources, we collected the data, including the basic information, audiological records, genetic information, and medication. The literature review was conducted with the software of EXCEL and SPSS 19.0.Results Among the collected 324 cases from 39 publications, 285 cases carrying mtDNA 1555 mutation include 254 Chinese,18 other Asians and 13 non-Asians, and all the 39 cases carrying mtDNA C1494T mutation are Chinese. 230 cases had the specific history of using aminoglycoside antibiotic and 92 cases did not. However, two of them can hear normally one year later. A statistical analysis suggested that the degree of hearing loss in patients with treatment was significantly severer than patients without(X2=25.414,P0.05). In addition, the heterogeneous mutation rate and the degree of deafness had a significant positive correlation (R=0.823,P0.05)。另外,线粒体DNA 1555/1494突变异质率与耳聋程度显著正相关(R=0.823,P<0.05)。结论多种因素影响mtDNA A1555G/C1494T携带者的临床表现。对于线粒体DNA A1555G/C1494T相关耳聋进行早期耳聋基因诊断有重要的临床意义。对突变携带者,严禁使用氨基糖甙类抗生素。

    Luetje, Charles M; Brown, Sandra A; Cullen, Robert D

    2010-09-01

    We conducted a retrospective descriptive study of a series of 31 consecutively presenting patients who had been implanted with the Vibrant Soundbridge middle ear hearing device. All implantations had been performed by the senior author. Three of these patients had undergone bilateral implantation, and 4 others had undergone subsequent explantation and reimplantation in response to known or suspected device failure, giving us a total of 34 ears and 38 implants. Our goal was to ascertain short- and long-term outcomes as measured by conventional audiometry (pure-tone average at 1 to 6 kHz) and long-term benefit as defined by the use or nonuse of the device. We found that at the initial activation session 2 months postoperatively, the average hearing thresholds were within 3 dB of the preoperative thresholds in all 34 ears and all 38 implants. The mean short-term gain at activation in the 38 implants was 28.1 dB. Nineteen patients (20 ears) were available for long-term evaluation, with the length of follow-up ranging from less than 1 year to 11 years (mean: 7.3). Of these 20 ears, 9 demonstrated further gain (mean: 10.8 dB) despite any natural hearing deterioration; of the remaining 11 ears, gain was unchanged in 2, diminished in 7 (mean: -3.6 dB), and gain data were unavailable in 2. In the final analysis, there were 20 user ears and 10 nonuser ears; 4 ears were lost to all follow-up. We conclude that direct-drive hearing with the Vibrant Soundbridge middle ear hearing device is beneficial and provides sustained audiometric gain. Factors that have a significant impact on patient use or nonuse include difficulty in obtaining audiologic support and the direct and indirect costs of the device. Without audiologic or financial support, some patients may choose to become nonusers and to either switch to conventional hearing aid amplification or become apathetic about hearing improvement.

    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

    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

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

    The aim of the study was to evaluate mental distress and health-related quality of life in patients with bilateral partial deafness (high-frequency sensorineural hearing loss) before cochlear implantation, with respect to their audiological performance and time of onset of the hearing impairment. Thirty-one patients and 31 normal-hearing individuals were administered the Beck Depression Inventory (BDI), the State-Trait-Anxiety-Inventory (STAI) and the World Health Organization Quality of Life-BREF questionnaire (WHOQOL-BREF). Patients also completed the Nijmegen-Cochlear-Implant-Questionnaire (NCIQ), a tool for evaluation of quality of life related to hearing loss. Patients revealed increased depressive and anxiety symptoms, as well as decreased health-related quality of life (psychological health, physical health), in comparison with their healthy counterparts (t tests, p patients with a prelingual onset of hearing loss enhanced self-evaluated social interactions and activity (NCIQ), when their outcomes were contrasted with those obtained in individuals with postlingual partial deafness (p Patients not using hearing aids had better audiological performance and, therefore, better sound perception and speech production, as measured with NCIQ. There was no effect of hearing aid use with respect to mental distress. Additional statistically significant correlations seen in patients included those between a steeper slope hearing loss configuration (averaged pure-tone thresholds at 1 and 2 kHz with subtracted threshold at 0.5 kHz) and better audiometric speech detection, between audiometric thresholds and the subjectively rated sound perception (NCIQ), as well as left-ear audiometric word recognition scores and the subjectively perceived ability to recognize advanced sounds (NCIQ). In addition, a longer duration of postlingual deafness, as well as a younger age at the onset were both related to worse speech detection thresholds. The results of the study provide evidence

    Full Text Available Background: Although it is not a new disorder, in recent times we have attained a greater understanding of auditory neuropathy (AN. In this type of hearing impairment, cochlear hair cells function but AN victims suffer from disordered neural transmission in the auditory pathway. The auditory neuropathy result profile often occurs as a part of that of the generalized neuropathic disorders, indicated in approximately 30-40% of all reported auditory neuropathy/auditory dyssynchrony (AN/AD cases, with approximately 80% of patients reporting symptom onset over the age of 15 years. In the present report, the results of audiologic tests (behavioral, physiologic and evoked potentials on two young patients with generalized neuropathy are discussed.Case report: Two brothers, 26 and 17 years old, presented with speech perception weakness and movement difficulties that started at 12 years of age and progressed as time passed. In their last examination, there was a moderate to severe flat audiogram in the older patient and mild low tone loss in the younger one. The major difficulty of the patients was severe speech perception impairment that was not compatible with their hearing thresholds. Paresthesia, sural muscle contraction and pain, and balance disorder were the first symptoms of the older brother. Now he can only move with crutches and his finger muscle tonicity has decreased remarkably, with marked fatigue after a short period of walking. Increasing movement difficulties were noted in his last visit. Visual neuropathy had been reported in repeated visual system examinations for the older brother, with similar, albeit less severe, symptoms in the younger brother.In the present study of these patients, behavioral investigations included pure-tone audiometry and speech discrimination scoring. Physiologic studies consisted Transient Evoked Otoacoustic Emission (TEOAE and acoustic reflexes. Electrophysiologic auditory tests were also performed to determine

    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

    The present study focused on the comparison of mental health and quality of life (QoL) between chronic otitis media (COM) patients and the hearing population. The patients with chronic otitis media and healthy control group were enrolled in the study. The duration and severity of the auditory impairment were recorded. In addition to hearing loss (HL), the findings of each patient's other ear disorders (ear discharge and tinnitus) were also recorded. In both the groups, psychological symptom profile and health-related QoL were evaluated and compared using a sociodemographic questionnaire, the Symptom Check List 90-Revised Form (SCL-90-R), and the Short Form-36 (SF-36). According to SCL-90-R, somatization (p health perception (p social functioning (p mental health (p < 0.017) than those of control subjects. Our results indicated that COM patients with mild or moderate HL have poorer life quality and higher psychological problems. Psychological well being should be also considered in assessment of COM patients in addition to the clinical evaluation and audiological tests.

    2008-09-01

    Full Text Available Introduction: Vogt-Koyanagi-Harada's disease is a rare syndrome that affects tissues with melanocytes like eyes, central nervous system, skin and inner ear. It affects primarily Asians, Indians and Latin Americans and also women. Objective: To review in the literature the several aspects of Vogt-Koyanagi-Harada's disease focusing on its cause and also to study its otolaryngology aspects through online databases Cochrane, LILACS, MEDLINE, OMIM e SciELO. Literature Review: This exact cause remains unknown, but there are evidences of an autoimmune process against an antigenic component on the melanocyte configuring an inflammatory T-cell-mediated immune response. The HLADRB1* 0405 allele is the one that is most associated to the disease. The clinic manifestations are divided in four: prodromal, uveitic, chronic and recurrence stages. The otolaryngology's aspects occur at the uveitic stage. Hearing loss is sensorineural bilateral and quickly progressive and could be associated with tinnitus. The vestibular component is less affected with vertigo, nystagmus and abnormal vestibular reflex. The otolaryngology's manifestations do not influence the recurrences or complications and they also have great prognosis with the treatment established. The diagnosis of this syndrome is based on clinical criteria, but audiological test could help. The therapy is corticosteroid-based. Final Comments: The most important factor for prognosis is the immediately treatment. The rarity of this syndrome makes its diagnosis a challenge and the presence of deafness, tinnitus and vertigo must consider its diagnosis.

    Full Text Available Abstract: Paca (Cuniculus paca, one of the largest rodents of the Brazilian fauna, has inherent characteristics of its species which can conribute as a new option for animal experimantation. As there is a growing demand for suitable experimental models in audiologic and otologic surgical research, the gross anatomy and ultrastructural ear of this rodent have been analyzed and described in detail. Fifteen adult pacas from the Wild Animals Sector herd of Faculdade de Ciências Agrárias e Veterinárias, Unesp-Jaboticabal, were used in this study. After anesthesia and euthanasia, we evaluated the entire composition of the external ear, registering and ddescribing the details; the temporal region was often dissected for a better view and detailing of the tympanic bulla which was removed and opened to expose the ear structures analyzed mascroscopically and ultrastructurally. The ear pinna has a triangular and concave shape with irregular ridges and sharp apex. The external auditory canal is winding in its path to the tympanic mebrane. The tympanic bulla is is on the back-bottom of the skull. The middle ear is formed by a cavity region filled with bone and membranous structures bounded by the tympanic membrane and the oval and round windows. The tympanic membrane is flat and seals the ear canal. The anatomy of the paca ear is similar to the guinea pig and from the viewpoint of experimental model has major advantages compared with the mouse ear.

    Synchrotron radiation and x-ray microtomography based on absorption contrast (performed at HASYLAB at DESY/Hamburg and BAM/Berlin) have been used for imaging of temporal bones and various internal components in situ at spatial resolution down to 7 micrometers with potential enhancement into the submicron range. Due to the volume imaging approach, several hidden structures (e.g., intra-ossicular channels) were revealed. Using several 3D-image processing techniques all data have been segmented into objects (e.g., bony ossicles, ligaments, fluids, air spaces) and subsequently transformed into vectorized data models. Because they are based on the original voxel resolution their content of vector primitives (e.g., polygons) is huge compared to recent models. Therefore they became polygon-reduced to fit into current computation limitations. So far individual data models of the entire hearing apparatus from tympanic membrane to cochlea out of intact specimen, including separate models of ossicles, ligaments and other components have been obtained, provided, in interchangeable data formats (e.g. vector-based: IGES, STL, VRML) and introduced into FEA for modeling of acousto-mechanic transfer characteristics of the middle ear. Their pseudo and real 3D- visualizations (rendering, autosteroscopic display, enlarged solid models) allow easy understanding of the anatomy and pathology of the human hearing organ and may support patient and student education in the field of otology and audiology.

    We assessed the incidence of hearing loss and its relationship with clinical characteristics and pneumococcal serotypes in adults surviving pneumococcal meningitis. We analysed hearing loss in 531 adults surviving pneumococcal meningitis included in two prospective nationwide cohort studies performed from April 1998 through to October 2002 and March 2006 through to January 2009. Hearing loss was evaluated on admission and discharge for all patients. Severe hearing loss was assessed by pure tone average on audiology and corrected for age, or by the combination of hearing loss on discharge and a score on the Glasgow Outcome Scale below 5, which could not be explained by other neurological sequelae. A total of 531 episodes of pneumococcal meningitis with non-lethal outcome were included. Predisposing conditions for pneumococcal meningitis were present in the majority of patients (64%), most commonly otitis (36%). Hearing loss was present at discharge in 116 patients (22%) and was classified as mild in 53% and severe in 47%. Hearing loss was related to otitis (odds ratio [OR], 2.58; 95% confidence interval [CI], 1.66-4.02; p otitis, but not disease severity. Otitis and resulting perilympathic inflammation contribute to meningitis-associated hearing loss.

    Cisplatin is an effective drug used in the treatment of many cancers, yet its ototoxic potential places cancer patients, exposed to this drug, at risk of hearing loss, thus negatively impacting further on a patient's quality of life. It is paramount for health care practitioners managing such patients to be aware of cisplatin's ototoxic properties and the clinical signs to identify patients at risk of developing hearing loss. English peer-reviewed articles from January 1975 to July 2015 were assessed from PubMed, Science Direct, and Ebscohost. Seventy-nine articles and two books were identified for this review, using MeSH terms and keywords such as “ototoxicity”, “cisplatin”, “hearing loss”, and “ototoxicity monitoring”. This review provides an up-to-date overview of cisplatin-associated ototoxicity, namely, its clinical features, incidence rates, and molecular and cellular mechanisms and risk factors, to health care practitioners managing the patient with cancer, and highlights the need for a team-based approach to complement an audiological monitoring programme to mitigate any further loss in the quality of life of affected patients, as there is currently no otoprotective agent recommended routinely for the prevention of cisplatin-associated ototoxicity. It also sets the platform for effective dialogue towards policy formulation and strengthening of health systems in developing countries. PMID:28115933

    In the first half of the 20th century G. W. Stewart was a physics faculty member at the University of Iowa (UI) with a distinguished record of research and teaching, especially in acoustics. Much of his research focused on the design and use of several types of acoustical filters. Some apparatus which he developed or utilized are still housed in the Department of Physics and Astronomy or are available in detailed diagrams. Demonstration apparatus (apparently homemade) from his era are still available for use. Carl E. Seashore, a renowned psychologist also at UI in the early 20th century, had interdisciplinary interests linking psychology, speech and hearing, music, and acoustics. He was responsible for obtaining an Henrici harmonic analyzer, a mechanical Fourier analyzer manufactured in Switzerland, a special grant from the state legislature during Depression conditions provided the funding. It resides in the Department of Speech Pathology and Audiology at UI. The Grinnell College Physics Historical Museum houses a set of 18 Helmholtz resonators and a Savart bell and resonator. Apparatus at Iowa State University, the University of Northern Iowa, and other Iowa institutions will also be described. Pictures and diagrams as well as some actual apparatus will be exhibited.

    Hutchinson–Gilford progeria syndrome (HGPS) is an extremely rare, fatal, segmental premature aging syndrome caused by a mutation in LMNA that produces the farnesylated aberrant lamin A protein, progerin. This multisystem disorder causes failure to thrive and accelerated atherosclerosis leading to early death. Farnesyltransferase inhibitors have ameliorated disease phenotypes in preclinical studies. Twenty-five patients with HGPS received the farnesyltransferase inhibitor lonafarnib for a minimum of 2 y. Primary outcome success was predefined as a 50% increase over pretherapy in estimated annual rate of weight gain, or change from pretherapy weight loss to statistically significant on-study weight gain. Nine patients experienced a ≥50% increase, six experienced a ≥50% decrease, and 10 remained stable with respect to rate of weight gain. Secondary outcomes included decreases in arterial pulse wave velocity and carotid artery echodensity and increases in skeletal rigidity and sensorineural hearing within patient subgroups. All patients improved in one or more of these outcomes. Results from this clinical treatment trial for children with HGPS provide preliminary evidence that lonafarnib may improve vascular stiffness, bone structure, and audiological status. PMID:23012407

    Full Text Available Michael P Cannito, Joel C Kahane, Lesya ChornaSchool of Audiology and Speech-Language Pathology, The University of Memphis, Memphis, TN, USAAbstract: Aging of the larynx is characterized by involutional changes which alter its biomechanical and neural properties and create a biological environment that is different from younger counterparts. Illustrative anatomical examples are presented. This natural, non-disease process appears to set conditions which may influence the effectiveness of botulinum toxin injection and our expectations for its success. Adductor spasmodic dysphonia, a type of laryngeal dystonia, is typically treated using botulinum toxin injections of the vocal folds in order to suppress adductory muscle spasms which are disruptive to production of speech and voice. A few studies have suggested diminished response to treatment in older patients with adductor spasmodic dysphonia. This retrospective study provides a reanalysis of existing pre-to-post treatment data as function of age. Perceptual judgments of speech produced by 42 patients with ADSD were made by two panels of professional listeners with expertise in voice or fluency of speech. Results demonstrate a markedly reduced positive response to botulinum toxin treatment in the older patients. Perceptual findings are further elucidated by means of acoustic spectrography. Literature on vocal aging is reviewed to provide a specific set of biological mechanisms that best account for the observed interaction of botulinum toxin treatment with advancing age.Keywords: vocal aging, adductor spasmodic dysphonia, botulinum toxin, voice quality, speech fluency

    The paper gives an overview about two research projects, both dealing with optical head tracking in hearing applications. As part of the project "Development of a real-time low-cost tracking system for medical and audiological problems (ELCoT)" a cost-effective single camera 3D tracking system has been developed which enables the detection of arm and head movements of human patients. Amongst others, the measuring system is designed for a new hearing test (based on the "Mainzer Kindertisch"), which analyzes the directional hearing capabilities of children in cooperation with the research project ERKI (Evaluation of acoustic sound source localization for children). As part of the research project framework "Hearing in everyday life (HALLO)" a stereo tracking system is being used for analyzing the head movement of human patients during complex acoustic events. Together with the consideration of biosignals like skin conductance the speech comprehension and listening effort of persons with reduced hearing ability, especially in situations with background noise, is evaluated. For both projects the system design, accuracy aspects and results of practical tests are discussed.

    Objective: To analyze neurophysiological characteristics in infants and young children with auditory neuropathy (AN) and explore their clinical significance. Methods: Audiological measurements(acoustic immittance, EOAEs, ABR, CM, MLR and ERPs) and peripheral neurological tests were conducted and evaluated in 13 infants and young children with AN. Six of them received highresolution temporal bone CT scans and/or cerebral MRI examinations. Results: All of the children showed type "A" tympanograms with abseatation of stapedial reflexes. EOAEs were normal in 12 of 13 subjects. In one child who had a history of anoxia during the birth, the EOAEs were not elicited. Click-evoked ABRs were absent in 12 of 13 subjects when maximum output of the instrument was reached. The CM potentials were presented bilaterally in all individuals, which were independent of the EOAEs and ABR. Of eight cases tested, all had clear MLR and six showed normal ERPs(P300 and MMN). Peripheral neurological tests and radiological findings were within the normal ranges. Conclusion: The diagnosis of AN in infants and young children should focus on analyzing their neurophysiological characteristics,especially on CM,MLR and ERPs. Combined use of EOAEs, ABR and CM was recommended for hearing screening on newborns with high risk factors.

    Full Text Available The main clinical presentation of patients with primary antibody deficiency (PAD incorporates upper respiratory tract infections comprising otitis media, sinusitis and pneumonia. This study was designed to investigate clinical and paraclinical otological complications in major types of PAD. A cross sectional study was conducted on 55 PAD patients with diagnosis of selective IgA deficiency, common variable immunodeficiency (CVID, X-linked agammaglobulinemia (XLA, and hyper IgM syndrome. All patients underwent otological examinations, audiometry, and auditory brain stem response. Otological complications were detected in 54.5% of PAD patients. Conductive hearing loss was the main finding amongst PID patients (73.3% followed by sensorineural hearing loss which was present in 8 cases. Otitis media with effusion (21.8%, chronic otitis media (27.2%, tympanosclerosis with intact tympanic membrane (5.4% and auditory neuropathy (3.6% were most important found complications. CVID and XLA patients with prophylactic usage of antibiotics had lower rate of audiological complications (p=0.04 and otitis media with effusion (p=0.027. As our results showed, asymptomatic otological findings were not rare in PAD patients; therefore, a systematic otological investigation is recommended as an integral part of the management and follow-up of these patients.

    Full Text Available INTRODUCTION: Turner's syndrome (TS is caused by a partial or total deletion of an X chromosome, occurring in 1:2,000 to 1:5,000 live born females. Hearing loss is one of its major clinical manifestations. However, there are few studies investigating this problem. OBJECTIVES: To review the current knowledge regarding the epidemiology, etiology, clinical manifestations and diagnosis of hearing impairment in patients with TS. METHODS: A bibliographic search was performed in the Medline and Lilacs databanks (1980-2012 to identify the main papers associating Turner's syndrome, hearing impairment and its clinical outcomes. CONCLUSIONS: Recurrent otitis media, dysfunction of the Eustachian tube, conductive hearing loss during infancy and sensorineural hearing loss in adolescence are the audiologic disorders more common in ST. The karyotype appears to be important in the hearing loss, with studies demonstrating an increased prevalence in patients with monosomy 45,X or isochromosome 46,i(Xq. Morphologic studies of the cochlea are necessary to help out in the clarifying the etiology of the sensorineural hearing loss.

    In an effort to determine whether life in industrialized societies can have an effect on hearing, 90 natives from Easter Island over 45 years old were evaluated. They underwent complete clinical and audiological assessment and were divided into groups according to those having lived only on the island or those having lived in modern civilization. With all factors being equal, except exposure to modern civilization, our results showed that living in civilized societies has a significant negative effect on hearing; the severity is directly proportional to the years of exposure. The median hearing thresholds of natives always living on the island (men and women combined) was found to be similar to those of female citizens of the United States; there was no significant difference in hearing thresholds between men and women among these natives. These results suggest that there are no significant inherent racial differences nor significant inherent differences between males and females in the sensitivity of hearing. A relationship between aging and hearing was noted and interpreted as true or intrinsic presbycusis. There were no cases of otosclerosis, Meniere's disease, or exostoses of the external ear canal among natives who had always lived on the island. Pure natives were found not to be prone to otitis media in spite of having an extremely high incidence of severe upper respiratory tract allergies.

    Sudden sensorineural hearing loss is a clinical condition characterized by a sudden onset of unilateral or bilateral hearing loss. In recent years sudden deafness has been frequently described in association with anterior inferior cerebellar artery (AICA) infarction generally presenting along with other brainstem and cerebellar signs such as ataxia, dysmetria and peripheral facial palsy. The authors report a rare clinical case of a 53-year-old man who suddenly developed hearing loss and tinnitus without any brainstem or cerebellar signs. Computed tomography of his brain was normal, and the audiological results localized the lesion causing deafness to the inner ear. Surprisingly, magnetic resonance imaging showed an ischemic infarct in the right AICA territory. This case represents the fifth in the literature to date but it confirms that AICA occlusion can cause sudden deafness even without brainstem or cerebellar signs. Therefore, we recommend submitting the patient for neuroimaging, as an emergency, in order to exclude infarction of the AICA territory. By doing this, it may be possible to limit the extent of the lesion by commencing early therapy.

    Full Text Available The objective of the present study was to evaluate children born to HIV-infected mothers and to determine whether such children present auditory disorders or poor acquisition of the ability to localize sound. The population studied included 143 children (82 males and 61 females, ranging in age from one month to 30 months. The children were divided into three groups according to the classification system devised in 1994 by the Centers for Disease Control and Prevention: infected; seroreverted; and exposed. The children were then submitted to audiological evaluation, including behavioral audiometry, visual reinforcement audiometry and measurement of acoustic immittance. Statistical analysis showed that the incidence of auditory disorders was significantly higher in the infected group. In the seroreverted and exposed groups, there was a marked absence of auditory disorders. In the infected group as a whole, the findings were suggestive of central auditory disorders. Evolution of the ability to localize sound was found to be poorer among the children in the infected group than among those in the seroreverted and exposed groups.

    Full Text Available Items pertaining to hearing and hearing aids from the Hearing Aid Rehabilitation Questionnaire were applied to a heterogeneous sample of Dutch patients aged 55 years and more to evaluate their potential use in hearing screening. Subjects aged 55+ were recruited from a large general practitioners practice to participate. Three groups were formed: a group of 63 persons with a hearing aid, a group of 64 without a hearing aid but with sufficient hearing impairment to qualify for hearing aid reimbursement, and a group of 85 non-hearing impaired persons. Factor and reliability analyses revealed a structure with two scales regarding hearing, namely functionality and social hearing and three scales pertaining to hearing aids, namely hearing aid stigma, pressure to be assessed and not wanting a hearing aid. Scale validity was assessed with pure tone averages over the frequencies 1, 2 and 4 kHz and with a visual analogue scale for subjective hearing. The derived scales can be applied reliably in audiological assessment in an adult hearing screen setting to detect experienced hearing problems as well as attitudes related to hearing and hearing aids.

    In speech audiometric testing, hearing performance is typically measured by calculating the number of correct repetitions of a speech stimulus. We investigate to what extent the repetition accuracy of Dutch speech stimuli presented against a background noise is influenced by nonauditory processes. We show that variation in verbal repetition accuracy is partially explained by morpholexical and syntactic features of the target language. Verbs, prepositions, conjunctions, determiners, and pronouns yield significantly lower correct repetitions than nouns, adjectives, or adverbs. The reduced repetition performance for verbs and function words is probably best explained by the similarities in the perceptual nature of verbal morphology and function words in Dutch. For sentences, an overall negative effect of syntactic complexity on speech repetition accuracy was found. The lowest number of correct repetitions was obtained with passive sentences, reflecting the cognitive cost of processing a noncanonical sentence structure. Taken together, these findings may have important implications for the audiological practice. In combination with hearing loss, linguistic complexity may increase the cognitive demands to process sentences in noise, leading to suboptimal functional hearing in day-to-day listening situations. Using test sentences with varying degrees of syntactic complexity may therefore provide useful information to measure functional hearing benefits.

    Full Text Available BACKGROUND: The prevalence of isolated hearing loss (HL associated with the m.3243A>G mutation is unknown. The aim of this study was to assess the frequency and heteroplasmy level of the m.3243A>G mutation in a large group of Polish patients with postlingual bilateral sensorineural HL of unidentified cause. METHODOLOGY/PRINCIPAL FINDINGS: A molecular search was undertaken in the archival blood DNA of 1482 unrelated patients with isolated HL that had begun at ages between 5 and 40 years. Maternal relatives of the probands were subsequently investigated and all carriers underwent audiological tests. The m.3243A>G mutation was found in 16 of 1482 probands (an incidence of 1.08% and 18 family members. Of these 34 individuals, hearing impairment was detected in 29 patients and the mean onset of HL was at 26 years. Some 42% of the identified m.3243A>G carriers did not develop multisystem symptomatology over the following 10 years. Mean heteroplasmy level of m.3243A>G was lowest in blood at a level of 14% and highest in urine at 58%. These values were independent of the manifested clinical severity of the disease. CONCLUSIONS: A single m.3243A>G carrier can usually be found among each 100 individuals who have postlingual hearing loss of unknown cause. Urine samples are best for detecting the m.3243A>G mutation and diagnosing mitochondrially inherited hearing loss.

    The objective of this study was to present 5 years of surgical experience, and the extended results of hearing preservation (based on 3-year follow-up), with the Med-El Vibrant Soundbridge (VSB) in which the floating mass transducer (FMT) is placed directly against the round window membrane, and the fascia is used only as covering tissue to keep it in position. A retrospective survey of surgical and audiological data was conducted to evaluate the performance and stability of patient hearing, with audiometric measurements performed over fixed time intervals up to 36 months. 21 patients, aged 19-62 years (mean 48.4), with mixed or conductive, bilateral or unilateral hearing loss were included in this study. Surgical intervention involved monaural implantation of the Med-El VSB between 2006 and 2009. The results were assessed using pure tone audiometry. In 5 years of experience with the technique, no significant complications or device extrusion were observed except for two revision surgeries requiring FMT repositioning. In the 3-year follow-up, we observed stable hearing in the implanted ear. It is concluded that direct round window stimulation without interposed fascia is an alternative for patients with hearing impairment caused by chronic otitis media and/or lack of ossicles, especially after modified radical mastoidectomy. It allows good results in a selected group of patients, although further observation on a larger population is needed to confirm long-term validity and effectiveness.

  6. Indications and candidacy for active middle ear implants.

    Currently, there are two active middle ear implants available commercially: the Vibrant Soundbridge system and the Carina system. A third active middle ear implant, the Esteem, is under clinical evaluation. All devices are indicated for patients with moderate-to-severe hearing loss. Because active middle ear implants are directly coupled to middle ear structures, many of the problems that patients with conventional hearing aids report, such as acoustic feedback, occlusion, and irritation of the outer ear canal, are avoided. In addition, AMEI patients perform well in background noise. However, indications for AMEIs are selective and candidates should be carefully evaluated before surgery. Before considering an AMEI, patients should be provided with conventional hearing aids. Only when benefit is insufficient and audiological selection criteria are met is further candidacy evaluation indicated. Since Colletti described coupling the Vibrant Soundbridge directly onto the round window membrane in 2006, the indications for the Vibrant Soundbridge have expanded and the VSB is implanted in patients with conductive and mixed hearing losses. Patients have often undergone middle ear surgery before. Especially mixed hearing loss cases with 30-60 dB HL sensorineural hearing impairment and 30-40 dB HL air-bone gaps may be helped by this new application.

    The aim of this study was to compare oval and round window vibroplasty. Eighteen (18) patients implanted with Vibrant Soundbridge (VSB) were enrolled. Two groups were formed depending on FMT placement: on round window in ten cases (RW group) and on oval window in eight (OW group). Pre and postoperative audiological tests were performed both under headphones and free-field settings, VSB on and off. One (1) RW patient experienced sudden hearing loss at the operated side after 4 months from surgery and was excluded from the analysis. Both groups showed good hearing results. Significant differences were measured at free-field pure-tone test with VSB on at 0.5 kHz (RW better than OW, p = 0.026) and 4 kHz (OW better than RW, p = 0.043). Both techniques share similar good results and are considered safe. However, we had one failure with deep and sudden hearing threshold worsening after some months of good results. From a surgical point of view OW vibroplasty is easier and safer to perform, when the stapes suprastructure is absent, as it does not require any drilling and should be preferred in such cases. More reports are needed to explain if RW vibroplasty is risky in a mid to long term.

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

  9. Assessment of senses of hearing and balance in chronic suppurative otitis media

    Full Text Available Chronic suppurative otitis media is among the most frequent illnesses treated in ENT wards. To establish the diagnosis, otomicroscopy alone usually suffice. Assessing the sense of hearing, often the sense of balance, too, is mandatory. Assessment of hearing will show the extent of conductive and sensorineural hearing loss. Apart from this, sometimes, when the finding is not obvious, it is necessary to conduct audiological investigation in more detail in order to establish whether the diagnosis of chronic suppurative otitis media is correct. Existence and extent of conductive hearing loss or confIrmation of tympanic membrane perforation by tympanometry can help a great deal. Also, some new results about the site of perforation and the middle ear volume influence on conductive hearing loss may help have a better insight into chronic suppurative otitis media. Assessing the sense of balance may show dysfunctions with not yet necessarily permanent damage: perilymphatic fistula and benign paroxysmal positional vertigo (BPPV. Unilateral or bilateral damage may be diagnosed with appropriate tests of vestibuloocular reflex (VOR: spontaneous nystagmus, head impulse test, head shaking test. These bedside tests do not require bulky, expensive equipment for stimulus delivery or special equipment for recording nystagmus. In addition, their significance is their ability to provide enough information without performing caloric testing which is contraindicated in chronic suppurative otitis media.

    Full Text Available Objective. To explore possible corelationship between the cochlear nerve deficiency (CND and unilateral auditory neuropathy (AN. Methods. From a database of 85 patients with unilateral profound sensorineural hearing loss, eight who presented with evoked otoacoustic emissions (EOAEs or cochlear microphonic (CM in the affected ear were diagnosed with unilateral AN. Audiological and radiological records in eight patients with unilateral AN were retrospectively reviewed. Results. Eight cases were diagnosed as having unilateral AN caused by CND. Seven had type “A” tympanogram with normal EOAE in both ears. The other patient had unilateral type “B” tympanogram and absent OAE but CM recorded, consistent with middle ear effusion in the affected ear. For all the ears involved in the study, auditory brainstem responses (ABRs were either absent or responded to the maximum output and the neural responses from the cochlea were not revealed when viewed by means of the oblique sagittal MRI on the internal auditory canal. Conclusion. Cochlear nerve deficiency can be seen by electrophysiological evidence and may be a significant cause of unilateral AN. Inclined sagittal MRI of the internal auditory canal is recommended for the diagnosis of this disorder.

  11. Hearing Disorders and Sensorineural Aging

    2014-01-01

    Full Text Available The physiological age-related hearing loss is defined as presbycusis and it is characterized by reduced hearing sensitivity and problems in understanding spoken language especially in a noisy environment. In elderly the reduced speech recognition is generally caused by a reduction of the cochlear cells in the organ of Corti and degeneration of the central auditory pathways. In order to have a complete management strategy of central and peripheral presbycusis the diagnostic evaluation should include clinical ENT examination, standard audiological tests, and tests of central auditory function. Treatment should include not only the appropriate instruments for peripheral compensation but also auditory rehabilitative training and counseling to prevent social isolation and loss of autonomy. Other common hearing disorders in elderly are tinnitus and hyperacusis which are often undervalued. Tinnitus is characterized by the perception of a “phantom” sound due to abnormal auditory perception. Hyperacusis is defined as a reduced tolerance to ordinary environmental sounds. Furthermore auditory, visual, nociceptive, and proprioceptive systems may be involved together in a possible context of “sensorineural aging.” The aim of this review is to underline the presence of hearing disorders like tinnitus and hyperacusis which in many cases coexist with hearing loss in elderly.

    2015-01-01

    Full Text Available Background. Hearing aids sold directly to consumers in retail stores or through the internet, without individual prescription by audiological professionals, are termed over-the-counter (OTC devices. This study aimed to determine whether there was any change in the electroacoustic characteristics of OTC devices compared to research carried out a decade earlier. The previous results indicated that most OTC devices were low-frequency-emphasis devices and were unsuitable for elderly people with presbycusis, who were likely to be the major consumers of these products. Methods. Ten OTC devices were selected and their electroacoustic performance was measured. Appropriate clients for the OTC devices were derived, using four linear prescription formulae, and OTC suitability for elderly persons with presbycusis was investigated. Results. OTC electroacoustic characteristics were similar to those in the earlier study. Most OTC devices were not acoustically appropriate for potential consumers with presbycusis. Although several of the devices could match prescriptive targets for individuals with presbycusis, their poor electroacoustic performance—including ineffective volume control function, high equivalent input noise, and irregular frequency response—may override their potential benefit. Conclusion. The low-cost OTC devices were generally not suitable for the main consumers of these products, and there has been little improvement in the appropriateness of these devices over the past decade.

    2009-03-01

    Full Text Available Introduction: Presbycusis is a public health problem. Despite its high prevalence, many elders do not have their hearing ability investigated periodically, because they do not have a specific complaint. Objective: To check whether there is a relationship between the complaint and the presence of hearing loss in elder people. Method: Transversal study in elders from a neighborhood in the city of Canoas, Rio Grande do Sul. After the definition of the neighborhood's geographic boundaries, all houses were visited, the older people's addresses were ascertained and the invitations to take part in the research were provided. A questionnaire survey was applied which had a question about hearing loss complaint and air-conducted hearing thresholds were obtained and studied. Out of the 72 identified elders 50 elders agreed to participate, 35 (70% women, and 15 (30% men. Results: It was confirmed that only 12 (24% elders showed a specific complaint of hearing loss, although 33 (66% elders showed slight, moderate, severe and profound hearing losses. Conclusion: Data analysis confirmed there was no relationship between the complaint and the presence of hearing loss in the assessed group, and demonstrated the need to forward the elders for audiological evaluation even without any specific complaint.

    2013-01-01

    Full Text Available The past decade has seen an escalating enthusiasm to comprehend chronic tinnitus from the perspective of both scientific understanding and clinical management. At the same time, there is a significant interest and commercial investment in providing targeted and individualized approaches to care, which incorporate novel sound-based technologies, with standard audiological and psychological strategies. Commercially produced sound-based devices for the tinnitus market include Co-ordinated Reset Neuromodulation ® , Neuromonics © , Serenade ® , and Widex ® Zen. Additionally, experimental interventions such as those based on frequency-discrimination training are of current interest. Many of these interventions overtly claim to target the underlying neurological causes of tinnitus. Here, we briefly summarize current perspectives on the pathophysiology of tinnitus and evaluate claims made by the device supporters from a critical point of view. We provide an opinion on how future research in the field of individualized sound-based interventions might best provide a reliable evidence-base in this growing area of translational medicine.

    2012-01-01

    Full Text Available Introduction: Organic solvents have been increasingly studied due to its ototoxic action. Objective: Evaluate the conditions of outer hair cells and olivocochlear system in individuals exposed to organic solvents. Method: This is a prospective study. 78 gas station attendants exposed to organic solvents had been evaluated from three gas stations from Santa Maria city, Rio Grande do Sul (RS. After applying the inclusion criteria, the sample was constituted by 24 individuals. The procedures used on the evaluation were audiological anamnesis, Transient otoacoustic emissions (TEOAES and research for the suppressive effect of TEOAES. A group control (GC compounded by 23 individuals was compared to individuals exposed and non-exposed individuals. The data collection has been done in the room of Speech Therapy of Workers Health Reference Center of Santa Maria. Results: The TEOAES presence was major in the left ear in both groups; the average relation of TEOAES signal/noise in both ears was greater in GE; the TEOAES suppressive effect in the right ear was higher in the individual of GE (62,5% and in the left ear was superior in GC (86,96%, with statistically significant difference. The median sign/noise ratio of TEOAES, according to the frequency range, it was higher in GC in three frequencies ranges in the right ear and one in the left ear. Conclusion: It was not found signs of alteration on the outer hair cells neither on the olivocochlear medial system in the individuals exposed to organic solvents.

    Full Text Available This study examined the relationship between hearing levels, otoacoustic emission levels and listening habits related to the use of personal listening devices (PLDs in adults with varying health-related fitness. Duration of PLD use was estimated and volume level was directly measured. Biomarkers of health-related fitness were co-factored into the analyses. 115 subjects ages 18–84 participated in this study. Subjects were divided into two sub-groups; PLD users and non-PLD users. Both groups completed audiological and health-related fitness tests. Due to the mismatch in the mean age of the PLD user versus the non-PLD user groups, age-adjusted statistics were performed to determine factors that contributed to hearing levels. Age was the most significant predictor of hearing levels across listening and health-related fitness variables. PLD user status did not impact hearing measures, yet PLD users who listened less than 8 hours per week with intensities of less than 80 dBA were found to have better hearing. Other variables found to be associated with hearing levels included: years listening to PLD, number of noise environments and use of ear protection. Finally, a healthy waist-to-hip ratio was a significant predictor of better hearing, while body mass index approached, but did not reach statistical significance.

  17. The clinical syndrome of bilirubin-induced neurologic dysfunction.

    Bhutani, Vinod K; Johnson-Hamerman, Lois

    2015-02-01

    Clinicians have hypothesized a spectrum of minor neurologic manifestations, consistent with neuroanatomical reports and collectively termed as a "syndrome of bilirubin-induced neurologic dysfunction (BIND)," which can occur in the absence of classical kernicterus. The current review builds on these initial reports with a focus on clinical signs and symptoms that are assessed by standardized tools and manifest from neonatal age to childhood. These clinical manifestations are characterized by the following domains: (i) neuromotor signs; (ii) muscle tone abnormalities; (iii) hyperexcitable neonatal reflexes; (iv) variety of neurobehavior manifestations; (v) speech and language abnormalities; and (vi) evolving array of central processing abnormalities, such as sensorineural audiology and visuomotor dysfunctions. Concerns remain that the most vulnerable infants are likely to acquire BIND, either because their exposure to bilirubin is not identified as severe enough to need treatment or is prolonged but slightly below current threshold levels for intervention. Knowing that a total serum/plasma bilirubin (TB) level is not the most precise indicator of neurotoxicity, the role of expanded biomarkers or a "bilirubin panel" has yet to be validated in prospective studies. Future studies that correlate early "toxic" bilirubin exposure to long-term academic potential of children are needed to explore new insights into bilirubin's effect on the structural and functional maturation of an infant's neural network topology.

    Isolated reports of hearing loss presenting as markings on the iris exist, but to date the effectiveness of iridology to identify hearing loss has not been investigated. This study therefore aimed to determine the efficacy of iridological analysis in the identification of moderate to profound sensorineural hearing loss in adolescents. A controlled trial was conducted with an iridologist, blind to the actual hearing status of participants, analyzing the irises of participants with and without hearing loss. Fifty hearing impaired and fifty normal hearing subjects, between the ages of 15 and 19 years, controlled for gender, participated in the study. An experienced iridologist analyzed the randomised set of participants' irises. A 70% correct identification of hearing status was obtained by iridological analyses with a false negative rate of 41% compared to a 19% false positive rate. The respective sensitivity and specificity rates therefore came to 59% and 81%. Iridological analysis of hearing status indicated a statistically significant relationship to actual hearing status (P iridology were not comparable to those of traditional audiological screening procedures.

    Objective To evaluate the effect of cochlear implantation with REZ-Ⅰ straight electrodes on residual hearing of postlingually deafened adults, and to explore the audiologically safety and injury characteristics of cochlear implantation. Methods Sixteen unilateral REZ-Ⅰ (22 channels) cochlear implantation recipients from September 2009 to December 2009 were picked out. Their pre-and postimplantation audiometry data including pure-tone audiometry (PTA), auditory steady-state responses (ASSR), auditory brainstem responses(ABR) and distortion product otoacoustic emissions(DPOAE) were retrospectively analyzed, in order to compare the change between pre- and post-implantation residual hearing. Results Among the 12 recipients who had some measurable residual hearing before implantation,5 (41.6%) patients had conserved some measurable hearing but the other 7 (58.4%) recipients had lost all measurable hearing after implantation on the implanted side. The implanted ears had an average PTA threshold drop of 9.5 dB HL and a statistically significant difference between pre- and post-implantation (P0.05).结论 REZ-Ⅰ型人工耳蜗植入会对植入侧残余听力造成一定程度的损伤.

    Full Text Available There have been a number of studies on screening of hearing in adult populations. Despite the high importance of interventions following screening for hearing (Wilson and Jungner, 1968 there is a dearth of information on the nature of interventions following such screening, other than hearing aid fitting (HA or referral to audiology/ENT departments (Pronk et al., 2011. In the late 1980s and early 1990s four studies were performed in Wales, which offered such other interventions to those individuals indicating hearing disabilities in screening questionnaires (eg Stephens et al., 1990; Davis et al., 1992. The majority of the patient notes from these studies were still accessible and have been examined to extract the following information: - what interventions were used other than hearing aids? - who received these interventions? - would they have been more appropriate than HAs for some of those fitted? The aim of this paper is to list the interventions provided in these studies and relate them to the initial complaints of those indicating hearing problems.

    2013-01-01

    Full Text Available Aim: To review the literature about the effects of environmental noise on the hearing ability of firefighters. Method: The PubMed and Scielo databases were searched and studies from 2002 to 2012 that included the keywords firefighters, noise, and hearing loss were identified. Initially, 24 studies were selected, but only 10 met the inclusion criteria of investigating the effects of occupational noise on firefighters. Results: Only 2 (20% studies quantified levels of sound pressure and performed audiological tests to identify associations with noise intensity and 3 (30% questionnaire-based studies reported that these professionals are more susceptible to hearing loss. Four (50% studies found that noise exposure damages the auditory system in this population. Discussion: These findings indicate that there is a necessity for preventive measures to be adopted by this population since it is considered to be at risk. Conclusion: In recent years, there have been few studies of firefighters' exposure to occupational noise, but our findings show the importance of new studies that include proper means of quantifying their exposure to noise in different work environments, in order to identify possible adverse conditions as well as to aid in the diagnosis of hearing loss.

    Half of the malformations in the ear, nose, and throat region affect the ear. Malformations of the external ear (pinna or auricle with external auditory canal [EAC]) are collectively termed microtia. Microtia is a congenital anomaly that ranges in severity from mild structural abnormalities to complete absence of the external ear (anotia). Microtia occurs more frequently in males (∼2 or 3:1), is predominantly unilateral (∼70-90%), and more often involves the right ear (∼60%). The reported prevalence varies geographically from 0.83 to 17.4 per 10,000 births. Microtia may be genetic (with family history, spontaneous mutations) or acquired. Malformations of the external ear can also involve the middle ear and/or inner ear. Microtia may be an isolated birth defect, but associated anomalies or syndromes are described in 20 to 60% of cases, depending on study design. These generally fit within the oculo-auriculo-vertebral spectrum; defects are located most frequently in the facial skeleton, facial soft tissues, heart, and vertebral column, or comprise a syndrome (e.g., Treacher Collins syndrome). Diagnostic investigation of microtia includes clinical examination, audiologic testing, genetic analysis and, especially in higher grade malformations with EAC deformities, computed tomography (CT) or cone-beam CT for the planning of surgery and rehabilitation procedures, including implantation of hearing aids.

    Full Text Available INTRODUCTION: The biological processes involved in noise-induced hearing loss (NIHL are still unclear. The involvement of inflammation in this condition has been suggested. OBJECTIVE: To investigate the association between interleukin - 6 (IL-6 polymorphism and susceptibility to NIHL. METHODS: This was a cross-sectional study with a sample of 191 independent elderly individuals aged > 60 years of age. Information on exposure to occupational noise was obtained by interviews. Audiological evaluation was performed using pure tone audiometry and genotyped through PCR by restriction fragment length polymorphism - PCR-RFLP. Data were analyzed using the Chi-square test and the Odds ratio (OR, with the significance level set at 5%. RESULTS: Among elderly with hearing loss (78.0%, 18.8% had a history of exposure to occupational noise. There was a statistically significant association between the genotype frequencies of the IL-6 -174 and NIHL. The elderly with the CC genotype were less likely to have hearing loss due to occupational noise exposure when compared to those carrying the GG genotype (OR = 0.0124; 95% CI 0.0023-0.0671; p < 0.001. CONCLUSION: This study suggests there is an association of polymorphisms in the IL- 6 gene at position - G174C with susceptibility to noise-induced hearing loss.

    Paranasal sinusitis is a condition that is treated by a General Practitioner and in case it fails it requires specialistic therapy. In most cases the inflammation is connected with nasal mucosa infection. However, in older children and adolescents sinusitis caused by spreading of tooth and gingiva inflammatory process can be an essential therapeutic and diagnostic problem. It is most often connected with periapical lesions, complications following dental procedures and oroantral fistula inflammation. Inflammatory process originally concerns maxillary sinus, however, it often undergoes generalization and it affects all or most of sinuses unilaterally or bilaterally. In microbiology of odontogenic sinusitis the dominant bacteria are the bacteria typical for peridental lesions (Streptococcus sanguis, Streptococcus salivarius, Streptococcus mutans and anaerobic bacteria). Odontogenic sinusitis frequently causes life threatening complications that require heroic drug and surgical treatment. Therapeutic and diagnostic problems are presented in case studies of 5 children aged from 10 to 17, who are treated in Children's Otolaryngology, Audiology and Phoniatrics Clinic in Łódź. There seems to be the need to emphasize the importance of thorough examination of oral cavity in all the children suffering from sinusitis, especially unilateral sinusitis. It is so essential on account of the gravity of the problem and serious complications that accompany the conditions.

    Congenital aural atresia (CAA) poses significant challenges to surgical remediation. Both bone anchored hearing aids (BAHA) and the Vibrant Soundbridge (VSB) have been considered as alternatives or adjuncts to conventional atresiaplasty. A consensus statement on VSB implantation in children and adolescents recommended against implantation when the Jahrsdoerfer score was less than 8. More recent publications suggest that patients with Jahrsdoerfer scores between three and seven may benefit from VSB implantation. The purpose of this study was to further investigate the outcomes of VSB implantation in CAA. The study was a multi-center, retrospective review. A retrospective review of data (patient's demographic, clinical, implant and audiological information) from four collaborating centers that have performed VSB implantation in CAA was performed. Outcomes based on severity of the atresia using the Jahrsdoerfer and Yellon-Branstetter scoring systems were also evaluated. Data from 28 patients from the four centers revealed no iatrogenic facial nerve injuries or change in bone thresholds. Post-operative speech threshold and speech recognition was, respectively, 39 dB and 94%. Jahrsdoerfer and Yellon scores ranged from 4 to 9 and 4 to 12, respectively. The scores did not correlate to or predict outcomes. Three individual elements of the scores did correlate to initial, but not long-term outcomes. Atresiaplasty and BAHA in the management of CAA are not complete solutions. VSB may offer an alternative in these surgically complex patients for achieving amplification, though better metrics for patient selection need to be developed. LEVEL OF EVIDENCE : IV.

    American Speech-Language Association (ASHA) and the International Association of Physicians in AIDS Care (IAPAC) reported that speech-language and hearing disorders that occur as a direct or indirect consequence of HIV-infection are so common. However there has been little research into the nature and onset of such communication disorders in children living with HIV. Therefore the purpose of the study is to understand about the nature and onset of audiological and speech-language disorders of a group of children with HIV for the better management. In methodology 67 children (4-16 years, mean: 11.06) with HIV infection took part in the study. Otoscopic examination, Pure-tone and Impedance audiometry, REELS, SECS, PAT, FDA and BUFFALO-III was used to assess. In result, 22/67 individuals had hearing loss, 17/67 had swallowing disorder, 21/67 individuals had voice problems. Language development was delayed in 21/67 of the individuals at the pragmatic and syntactic level and 7/67 had the deviant language. There was negative correlation (r=-0.932) between the duration of HIV infection and degree of severity of communication disorders in the participants.

    Full Text Available Objective: Viral diseases are one of the common causes of hearing loss. The inner ear may be involved directly or by secondary reaction (e.g., polyarthritis nodosa. This study was performed to investigate the relation between positive HBS-Ag (hepatitis B disease and hearing loss.Methods: This case-study research was done on 95 hepatitis-B patients as the case group and 97 normal cases as the control group. They were selected sequentially and audiologic tests were performed on the participants. The hearing thresholds of the two groups were compared using the t-test.Results: According to audiometry results, pure tone average (mean thresholds of 500, 1000 and 2000 Hz were 22.1 dB for the left ear and 23.95 dB for the right ear in hepatitis-B group and 8.4 dB for the left ear and 8.95 dB for the right ear in the control group (HBS-Ag negative. The difference between two groups was statistically significant with p-value less than 0.05.Conclusion: The results show that hepatitis-B patients are more prone to hearing loss and that hepatitis B disease can cause hearing loss. This study suggests that hepatitis B prophylaxis is important in decreasing hepatitis-B involvement and therefore, hearing loss.

    Full Text Available CONTEXT: Meningoencephalitis early in life, of any etiology, is a risk factor for development of subsequent sequelae, which may be of physical, psychiatric, behavioral or cognitive origin. Anomia is a language abnormality frequently found in such cases, and other language deficits are rarely described. The aim of this study was to describe the cognitive and linguistic manifestations following a case of herpetic meningoencephalitis in a 13-year-old patient with eight years of schooling. CASE REPORT: The patient underwent a speech-language audiology assessment nine months after the neurological diagnosis. The battery of tests included the Montreal-Toulouse Language Assessment test protocol (MT Beta-86, modified, the description from the Cookie Theft task of the Boston Diagnostic Aphasia Examination (BDAE, an informal assessment of the patient's logical and mathematical reasoning, and the neuropsychological subtests from the WAIS-III scale, which assess working memory. The patient presented mixed aphasia, impairment of short-term memory and working memory, and dyscalculia. This case also presented severe cognitive and linguistic deficits. Prompt diagnosis is crucial, in order to enable timely treatment and rehabilitation of this neurological infection and minimize the cognitive deficits caused by the disease.

    Full Text Available Introduction: Otoacoustic emissions can be an alternative for cochlear evaluation in noise induced hearing loss (NIHL. Objective: To investigate the correlation between the findings of audiometry results and distortion product otoacoustic emissions (DPOAE in the military police. Method: from cross-sectional and retrospective study, 200 military police officers were submitted to audiological evaluation - pure tone audiometry and DPOAE. Results: considering the provisions of Ordinance 19 of the Labour Department, the results were suggestive of induced hearing loss by high sound pressure levels in 58 individuals, distributed as follows: 28 (48.3% bilateral cases and 30 (51.7% unilateral cases, and 15 (25.85% in each ear. The correlation between the audiometric and DPOAE showed statistical significance in most of the frequencies tested in both ears, confirming that the greater the degree of hearing loss, the smaller the DPOAE amplitudes. In addition, there was observed significant difference between the DPOAEs amplitudes of normal subjects and listeners with hearing loss, confirming the lowering of responses in the group with hearing loss. Conclusion: considering that the correlation between pure tone audiometry and DPOAE, we conclude that otoacoustic emissions can be a complementary tool for the detection and control of NIHL in military police.

    Full Text Available Introduction: Vestibular migraine (VM is a vestibular syndrome seen in patients with migraine and is characterized by short spells of spontaneous or positional vertigo which lasts between a few seconds to weeks. Migraine and VM are considered to be a result of chemical abnormalities in the serotonin pathway. Neuhauser′s diagnostic criteria for vestibular migraine is widely accepted. Research on VM is still limited and there are few studies which have been published on this topic. Materials and Methods: This study has two parts. In the first part, we did a retrospective chart review of eighty consecutive patients who were diagnosed with vestibular migraine and determined the frequency of auditory dysfunction in these patients. The second part was a prospective case control study in which we compared the audiological parameters of thirty patients diagnosed with VM with thirty normal controls to look for any significant differences. Results: The frequency of vestibular migraine in our population is 22%. The frequency of hearing loss in VM is 33%. Conclusion: There is a significant difference between cases and controls with regards to the presence of distortion product otoacoustic emissions in both ears. This finding suggests that the hearing loss in VM is cochlear in origin.

    We formulated policies and procedures for allied health professionals (AHPs) who provide services using telehealth in Nunavut, Canada's newest Arctic territory. These are a supplement to the clinical policies and procedures already established for Nunavut physicians and nurses. The services were in the areas of audiology, dietetics/nutrition, midwifery, occupational therapy, ophthalmic services, pharmacy, physiotherapy, psychology, respiratory therapy, social work and speech therapy. Documents specific to each of the services were developed, drawing on information from Government of Nunavut data, Nunavut healthcare providers and links made through the Internet. Topics included the scope and limitations of telehealth services, staff responsibilities, training and reporting, professional standards and cultural considerations. We also considered generic policies covering common issues such as jurisdiction, licensing and liability. The policies and procedures for AHPs will enhance and expand the successes already achieved with telehealth in Nunavut. The challenges are to balance the preferred approaches to service provision with the realities of health care and communications in an Arctic setting.

    2011-01-01

    Congenital cytomegalovirus (CMV) infection is an important public health problem with approximately 7 in 1,000 newborns infected and consequently at risk for hearing impairment. Newborn hearing screening will fail to detect this hearing impairment in approximately half of the cases because late onset hearing loss is frequent. Hearing impairment has profound impact on cognitive and social development of children and their families, determining most of the disease burden of congenital CMV infection. The potential value of newborn screening for congenital CMV is increasingly discussed. To date, many experts acknowledge the benefit of antiviral treatment in the prevention of hearing deterioration in newborns with neurological symptoms, and the benefit of early identification of late-onset hearing impairment by means of extensive audiological follow up of infected infants. These opinions imply that the potential of newborn screening for CMV would lie in the identification of the large proportion of asymptomatic congenitally infected newborns at risk for developing late-onset hearing loss. Experience with postnatal antiviral treatment of symptomatic newborns is encouraging, but has not been studied in asymptomatic congenitally infected newborns. A large-scale study on the safety and effectiveness of combined screening and antiviral therapy for congenital CMV infection is the necessary next step to take and should not be delayed.

  17. Early detection of hearing loss

    Directory of Open Access Journals (Sweden)

    Schade, Götz

    2008-01-01

    Full Text Available The universal newborn hearing screening (UNHS is currently spreading in Germany, as well, even though there can be no talk of a comprehensive establishment. The introduction of UNHS in several federal states such as Hamburg, Hessen, and Schleswig-Holstein can be ascribed to the personal commitment of individual pediatric audiologists. Apart from the procurement of the screening equipment and the training of the staff responsible for the examination of the newborns, the tracking, i.e. the follow-up on children with conspicuous test results, is of utmost importance. This involves significant administration effort and work and is subject to data protection laws that can differ substantially between the various federal states. Among audiologists, there is consensus that within the first three months of a child’s life, a hearing loss must be diagnosed and that between the age of 3 and 6 months, the supply of a hearing aid must have been initiated. For this purpose, screening steps 1 (usually a TEOAE measurement and 2 (AABR testing need to be conducted in the maternity hospital. The follow-up of step 1 then comprises the repetition of the TEOAE- and AABR measurement for conspicuous children by a specialized physician. The follow-up of step 2 comprises the confirmatory diagnostics in a pediatric audiological center. This always implies BERA diagnostics during spontaneous sleep or under sedation. The subsequent early supply of a hearing aid should generally be conducted by a (pediatric acoustician specialized on children.

    The past decade has seen an escalating enthusiasm to comprehend chronic tinnitus from the perspective of both scientific understanding and clinical management. At the same time, there is a significant interest and commercial investment in providing targeted and individualized approaches to care, which incorporate novel sound-based technologies, with standard audiological and psychological strategies. Commercially produced sound-based devices for the tinnitus market include Co-ordinated Reset Neuromodulation ® , Neuromonics © , Serenade ® , and Widex ® Zen. Additionally, experimental interventions such as those based on frequency-discrimination training are of current interest. Many of these interventions overtly claim to target the underlying neurological causes of tinnitus. Here, we briefly summarize current perspectives on the pathophysiology of tinnitus and evaluate claims made by the device supporters from a critical point of view. We provide an opinion on how future research in the field of individualized sound-based interventions might best provide a reliable evidence-base in this growing area of translational medicine.

    To evaluate the CT and MRI findings of the large endolymphatic duct or sac syndrome (LEDS) and its associated anomalies, with clinical features. We retrospectively reviewed the MR and CT images of 52 ears obtained from 26 patients with LEDS. We reviewed the clinical findings, audiology testing, and treatment results. The degree of hearing loss was classified from normal to profound, based on pure tone audiometry. The largest areas were measured at each endolymphatic duct and analyzed to determine whether a correlation exists with the degree of hearing loss. We also analyzed the differences in measurements between CT and MRI findings. All 26 patients had some degree of sensorineural hearing loss, which resulted in 18 ears to undergo a cochlear implantation. One patient was diagnosed with Cornelia de Lange syndrome. Five patients had a sudden hearing loss onset. Ten ears had incomplete cochlear partitions, whereas 28 ears had enlarged vestibules. All patients had severe to profound hearing loss. We found no statistical correlation between the size of the largest area of the endolymphatic duct and the degree of hearing loss. The mean area of the endolymphatic ducts, as per an MRI examination, revealed slightly greater areas than the CT findings, although the differences were not significant. Enlarged vestibules and incomplete partitions of the cochlea were common anomalies associated with LEDS. We found no statistical correlation between the largest area of the endolymphatic duct or sac with the degree of hearing loss.

    The purpose of this study was to examine the current status of newborn/infant hearing screening programs in public sector hospitals in South Africa by means of a descriptive survey. Data was gathered using a self-administered postal questionnaire, which included questions on screening resources and protocols, follow-up, diagnostic, and information management procedures as well as timing of intervention. The questionnaire was sent to 86 speech therapy and audiology departments within public sector hospitals throughout South Africa and 44 questionnaires were returned. The findings indicated that 27% (n=12) of respondents were conducting some form of hearing screening. The most frequently reported reasons for the absence of a screening program were a lack of appropriate equipment and a shortage of staff. Institutions with active screening programs face many challenges and programs are mostly unsystematic. Reported findings make a valuable contribution to the field of early hearing detection and intervention by providing a baseline for the development and structuring of early hearing detection and intervention services as a priority in the public healthcare sector of South Africa.

    To assess the capability of three-dimensional fluid-attenuated inversion recovery (3D-FLAIR) sequences in detecting signal alterations of the endolabyrinthine fluid in patients with otosclerosis. 3D-FLAIR before and after (-/+) gadolinium (Gd) administration was added to the standard MR protocol and acquired in 13 patients with a clinical/audiological diagnosis of severe/profound hearing loss in otosclerosis who were candidates for cochlear implantation and in 11 control subjects using 3-T magnetic resonance imaging (MRI) equipment. The MRI signal of the fluid-filled cochlea was assessed both visually and calculating the signal intensity ratio (SIR = signal intensity cochlea/brainstem). We revealed no endocochlear signal abnormalities on T1-weighted -/+ Gd images for either group, while on 3D-FLAIR we found bilateral hyperintensity with enhancement after Gd administration in eight patients and bilateral hyperintensity without enhancement in one patient. No endocochlear signal abnormalities were detected in other patients or the control group. Using 3-T MRI equipment, the 3D-FLAIR -/+ Gd sequence is able to detect the blood-labyrinth barrier (BLB) breakdown responsible for alterations of the endolabyrinthine fluid in patients with cochlear otosclerosis. We believe that 3D-FLAIR +/- Gd is an excellent imaging modality to assess the intra-cochlear damage in otosclerosis patients. (orig.)

    Full Text Available Introduction The presence of noise in our society has attracted the attention of health professionals, including speech-language pathologists, who have been charged along with educators with developing hearing conservation programs in schools. Objective To describe the results of three strategies for awareness and hearing preservation in first to fourth grades in public elementary schools. Methods The level of environmental noise in classrooms was assessed, and 638 elementary school students from first to fourth grades, 5 to 10 years of age, were audiologically evaluated. After the evaluations, educational activities were presented to children and educators. Results The noise level in the classroom ranged from 71.8 to 94.8 A-weighted decibels. The environment of the classroom was found to promote sound reverberation, which hinders communication. Thirty-two students (5.1% presented hearing alterations. Conclusion The application of strategies for a hearing conservation program at the school showed that noise is present in the room, and hearing loss, sometimes silent, affects schoolchildren. Students and teachers were aware that hearing problems can be prevented. Avoiding exposure to noise and improving the acoustics in classrooms are essential.

    The objective of the present work was to experimentally estimate the potential of the tone audiometry technique for the determination of the sound-absorbing properties of various material. The study included 15 subjects at the age from 19 to 32 years. Their audiological examination was followed by the placement of the 5×7 cm spacer plate from the study material beneath the bone vibrator telephone to determine the bone sound-conduction threshold; no air-marking was undertaken. The sound absorption by the study materials of interest was determined in each octave-band from 250 to 8000 Hz from the difference between the starting audiogram and the audiogram of the material of interest. The study was carried out in three stages: (1) evaluation of sound absorption of each of the five materials, (2) measurement of the same parameter in the combinations of 2--4 layers for increasing sound absorption, and (3) fixation of the bone conduction telephone by the operator's hand (the head-mounted harness was used for the same purpose at stages 1 and 2). The experiments demonstrated that the study of bone sound conduction by means of tone audiometry allows to estimate the sound absorption of various materials. This technique may be applied for the development of a subjective method for the measurement of sound absorption in order to evaluate the acoustic effectiveness of materials that can be used to construct individual protective anti-noise devices.

    Audiometry observations were analyzed for 290 irradiated survivors of the 1945 atomic bomb in Hiroshima and in 293 nonirradiated subjects. The study was undertaken in order to determine the age changes in audiology in irradiated and nonirradiated subjects as well as to investigate the pattern of hearing levels in a Japanese population for comparison with patterns in Caucasians. The following statistical observations were made. Correlation between hearing levels for right and left ear. Correlation between hearing levels at various cycles. Changes in hearing levels by age and sex. The relation between age and decibel loss was not linear and correlation ratios with age were 0.45 to 0.72. Audiometry seems to be of some value as one of a battery of tests of physiologic aging designed for detection of irradiation induced nonspecific aging acceleration. In this relatively small sample, no differences in hearing acuity were detected in the atomic bomb survivors as compared with the control sample. 6 references, 3 figures, 9 tables.

    Objective. The aim of this study is to analyze the high-frequency hearing levels in patients with rheumatoid arthritis and to determine the relationship between hearing loss, disease duration, and immunological parameters. Materials and Methods. A descriptive cross-sectional study including fifty-three patients with rheumatoid arthritis was performed. The control group consisted of 71 age- and sex-matched patients from the study population (consecutively recruited in Madrid "Area 9," from January 2010 to February 2011). Both a pure tone audiometry and an extended-high-frequency audiometry were performed. Results. Extended-high-frequency audiometry diagnosed sensorineural hearing loss in 69.8% of the patients which exceeded the results obtained with pure tone audiometry (43% of the patients). This study found significant correlations in patients with sensorineural hearing loss related to age, sex, and serum anti-cardiolipin (aCL) antibody levels. Conclusion. Sensorineural hearing loss must be considered within the clinical context of rheumatoid arthritis. Our results demonstrated that an extended-high-frequency audiometry is a useful audiological test that must be performed within the diagnostic and follow-up testing of patients with rheumatoid arthritis, providing further insight into a disease-modifying treatment or a hearing loss preventive treatment.

    Full Text Available Introduction: Studies on the occupational exposure show that noise has been reaching a large part of the working population around the world, and NIHL (noise-induced hearing loss is the second most frequent disease of the hearing system. Objective: To review the audiometry results of employees at the campus of the University of São Paulo, Bauru. Method: 40 audiometry results were analyzed between 2007 and 2008, whose ages comprised between 32 and 59 years, of both sexes and several professions: gardeners, maintenance technicians, drivers etc. The participants were divided into 2 groups: those with tonal thresholds within acceptable thresholds and those who presented auditory thresholds alterations, that is tonal thresholds below 25 dB (NA in any frequency (Administrative Rule no. 19 of the Ministry of Labor 1998. In addition to the Conventional Audiologic Evaluation (250Hz to 8.000Hz we also carried out High Frequencies Audiometry (9000Hz, 10000Hz, 11200Hz, 12500Hz, 14000Hz and 16000Hz. Results: According to the classification proposed by FIORINI (1994, 25.0% (N=10 they presented with NIHL suggestive audiometric configurations. The results of high frequencies Audiometry confirmed worse thresholds than those obtained in the conventional audiometry in the 2 groups evaluated. Conclusion: The use of high frequencies audiometry proved to be an important register as a hearing alteration early detection method.

    Results are presented from a study of the prevalence of middle and external ear disorders in coal miners who work underground. The study followed from an earlier NIOSH report (1976) that indicated a possibly large number of otoscopic abnormalities in this population of workers. Otoscopic examinations, pure tone air- and bone-conduction audiometry tests, and impedance tests were administered to 350 underground miners and 150 industrial workers not associated with mining. The study was conducted completely within a hospital otolaryngology/audiology clinic setting. Results of the investigation showed a highly similar prevalence of middle ear and ear canal abnormalities in the miner group and the control group (19 percent). Middle ear abnormalities observed in the miners were judged by the examining otolaryngologists to have preceded their experience in the mines and were not related solely to underground noise exposure or coal dust. Nearly half of the subjects who had an air-bone gap had no middle ear abnormality observable by otoscopic examination. There was substantial agreement between the finding of abnormal otoscopy and abnormal tympanometry. By itself, acoustic reflex was not useful in identifying middle ear disorders, since this reflex may be absent for other reasons, including presence of severe sensorineural hearing loss.

    Objective:Based on the clinical manifestations of a hearing loss patient, the POU3F4 gene was tested for diagnosis of etiology. Methods:A comprehensive physical examination was performed on the proband to exclude abnormalities of other organs, and detailed audi-ological testing and temporal bone CT scan were also performed. Genomic DNA was extracted using the proband's peripheral blood leukocytes. Polymerase chain reactions (PCR) were performed in the coding sequence of the POU3F4 gene. Direct DNA sequencing was subsequently applied to screen the entire coding region of the POU3F4 gene. Results:The proband had severe sensorineural hearing loss. Temporal CT showed bilateral cochlear incomplete partition, vestibule dysplasia, internal auditory canal fundus expansion, and cochlear interlink with the internal auditory canal fundus. A novel mutation (c.530C > A (p.S177X)) in the POU3F4 gene was found in this patient, creating an new stop codon and was predicted to result in a truncated protein lacking normal POU3F4 transcription factor function. Conclusion: Through analysis of the POU3F4 gene and clinical manifestations in the patient, we conclude that a novel mutation may have resulted in a premature stop codon, contributing to the mutation of POU3F4 gene.

    Full Text Available Sudden sensorineural hearing loss is defined as a loss of at least 30 dB in three contiguous frequencies over a period of three days or less. In the present study a client with sudden hearing loss post hypothyroidism is discussed. A 56 year old client reported of awakening from sleep due to ear fullness along with severe tinnitus and experienced reduced hearing sensitivity in the right ear. The client had a history of hypothyroidism and was under medication for the same. The successive audiological investigations revealed that there was no improvement from prescribed medications, even with early identification and intervention. For better treatment outcomes correct identification of the cause as well as application of cause based treatment procedure is essential. Endocrine disorder is said to be one of the causes for sudden sensorineural hearing loss and one among this disorder is hypothyroidism. The present study aimed to throw a light on this aspect by giving a detailed case report of the client who suffered sudden sensorineural hearing loss which is suspected to be a long term effect of hypothyroidism.

    An 8-year-old child diagnosed with attention deficit/hyperactivity disorder presented to our Department of Otolaryngology 4 days after suffering hearing loss, loss of balance, tinnitus, and fullness sensation of the left ear. Her symptoms occured with the first dose of methylphenidate. The medical history and physical examination revealed no other diseases associated with sudden hearing loss. The audiogram revealed a total hearing loss on the left ear. Stapedial reflexes, distortion product and transient-evoked otoacoustic emissions were absent in left ear. The absence of clinical, laboratory and radiological evidence of a possible cause for complaints, an association between methylphenidate and sudden hearing loss was suggested. The patient received a standard course of oral corticosteroid and hyperbaric oxygen therapy. Weekly otological and audiological examinations were performed. Conservative and medical treatments offered no relief from hearing loss. Sudden hearing loss is a serious and irreversible adverse effect of methylphenidate. Therefore, the risk of hearing loss should be taken into consideration when initiating methylphenidate therapy.

    2015-01-01

    Traditionally, audiology research has focused primarily on hearing and related disorders. In recent years, however, growing interest and insight has developed into the interaction of hearing and cognition. This applies to a person's listening and speech comprehension ability and the neural realization thereof. The present perspective extends this view to oral communication, when two or more people interact in social context. Specifically, the impact of hearing impairment and cognitive changes with age is discussed. In focus are executive functions, a group of top-down processes that guide attention, thought and action according to goals and intentions. The strategic allocation of the limited cognitive processing capacity among concurrent tasks is often effortful, especially under adverse communication conditions and in old age. Working memory, a sub-function extensively discussed in cognitive hearing science, is here put into the context of other executive and cognitive functions required for oral communication and speech comprehension. Finally, taking an ecological view on hearing impairment, activity limitations and participation restrictions are discussed regarding their psycho-social impact and third-party disability.

    Full Text Available Introduction Hearing loss is one of the most common problems in the elderly population. Besides compromising oral communication, it directly affects social relations and prevents elderly patients from living actively in society, possibly leading to the onset of depression or other conditions. Objective To analyze the effects of unilateral adaptation of hearing aids on symptoms of depression and the social activity constraints of elderly subjects with hearing impairment. Methods The sample consisted of elderly subjects with hearing loss who did not use hearing aids. Data were collected in two phases. Initially, all participants underwent an audiological assessment and answered the Hearing Handicap Inventory for Elderly (summarized version and the Geriatric Depression Scale. All subjects participated in the selection and hearing aid adaptation processes and became monaural hearing aid users. After 30 days of hearing aid use, they were assessed with the same instruments. The results of the questionnaires before and after hearing aid adaptation were compared. Results The sample consisted of 13 individuals, between 60 and 90 years old (mean 72.85 ± 11.05 years. Data analysis showed that there was significant improvement in social activity constraints (p < 0.001 and in symptoms of depression (p = 0.031. Conclusion Results show that, in the sample studied, unilateral hearing aid adaptation reduced social activity constraints and depression symptoms.

    Full Text Available INTRODUCTION: Auditory rehabilitation in children with bilateral severe-to-profound sensorineural hearing loss with cochlear implant has been developed in recent decades; however, the rehabilitation of children with cerebral palsy still remains a challenge to otolaryngology and speech therapy professionals. OBJECTIVE: To verify the effectiveness of cochlear implants in the development of auditory and language skills in children with cerebral palsy. METHODS: A prospective analytical study. The evaluation of auditory responses to speech test was applied to the children in this study at regular intervals following implantation. Standardized tests that assess and quantify the development of auditory and language skills were administered and speech therapy video records and speech therapy files were analyzed. All children went through individually tailored intensive audiological rehabilitation programs following cochlear implantation. RESULTS: Two participants had gradual auditory and language development when compared to other participants who reached advanced levels in hearing and oral language classifications. CONCLUSION: The use of the Cochlear implant enabled participants to reach advanced stages of hearing and language skills in three of the five participants with cerebral palsy in this study. This electronic device is a viable therapeutic option for children with cerebral palsy to help them achieve complex levels of auditory and language skills.

    2011-05-01

    A 5-year retrospective audit of demographic, audiological, and other records of 147 children implanted at one London centre was conducted. The aim was to detail the number of children implanted, with a specific focus on children from families with English as an additional language (EAL), and to compare these children with children from monolingual English-speaking families on a variety of characteristics known to affect paediatric cochlear implant outcomes. In all, 28% of children were from families where English is an additional language, with 15 different languages recorded. There were no differences between EAL and English-speaking children with respect to age of implantation; bilateral versus unilateral implants or hearing levels in better ear. There were differences between these groups in aetiology, in the occurrence of additional needs, and in educational placements. Information about speech and language outcomes was difficult to gather. Conclusions indicate the need for more detailed record-keeping especially about children's home languages for purposes of planning intervention and for the inclusion of children with EAL in future studies.

  17. Classification and diagnosis of ear malformations

    Bartel-Friedrich, Sylva

    2007-01-01

    Full Text Available In the ENT region 50% of the malformations affect the ear. Malformations of the outer and middle ear are predominantly unilateral (ca. 70-90% and mostly involve the right ear. Inner ear malformations can be unilateral or bilateral. The incidence of ear malformations is approximately 1 in 3800 newborns. Ear malformations may be genetic (associated with syndromes or not, with family history, spontaneous mutations or acquired in nature. Malformations can affect the outer ear (pinna and external auditory canal, EAC, middle ear and inner ear, not infrequently in combination. Formal classification is advisable in order to be able to predict the prognosis and compare treatment schedules. Various classifications have been proposed: pinna and EAC malformations according to Weerda [1], middle ear malformations according to Kösling [2], and inner ear malformations according to Jackler [3], [4], to Marangos [5] and to Sennaroglu [6]. Additionally, we describe Altmann’s classification of atresia auris congenita [7] and the Siegert-Mayer-Weerda score [8] for EAC and middle ear malformations, systems of great practicability that are in widespread clinical use. The diagnostic steps include clinical examination, audiological testing, genetic analysis and, especially, CT and MRI. These imaging methods are most usefully employed in combination. Precise description of the malformations by means of CT and MRI is indispensable for the planning and successful outcome of operative ear reconstruction and rehabilitation procedures, including cochlear implantation.

    Mee Hyun Song

    Full Text Available BACKGROUND: Branchio-oto-renal (BOR or branchio-otic (BO syndrome is one of the most common forms of autosomal dominant syndromic hearing loss. Mutations in EYA1, SIX1 and SIX5 genes have been associated with BOR syndrome. In this study, clinical and genetic analyses were performed in patients with BOR/BO syndrome focusing on auditory manifestations and rehabilitation. METHODS: The audiologic manifestations were reviewed in 10 patients with BOR/BO syndrome. The operative findings and hearing outcome were analyzed in patients who underwent middle ear surgeries. The modality and outcome of auditory rehabilitation were evaluated. Genetic analysis was performed for EYA1, SIX1, and SIX5 genes. RESULTS: All patients presented with mixed hearing loss. Five patients underwent middle ear surgeries without successful hearing gain. Cochlear implantation performed in two patients resulted in significant hearing improvement. Genetic analysis revealed four novel EYA1 mutations and a large deletion encompassing the EYA1 gene. CONCLUSIONS: Auditory rehabilitation in BOR/BO syndrome should be individually tailored keeping in mind the high failure rate after middle ear surgeries. Successful outcome can be expected with cochlear implantations in patients with BOR/BO syndrome who cannot benefit from hearing aids. The novel EYA1 mutations may add to the genotypic and phenotypic spectrum of BOR syndrome in the East Asian population.

    Full Text Available The paper gives an overview about two research projects, both dealing with optical head tracking in hearing applications. As part of the project “Development of a real-time low-cost tracking system for medical and audiological problems (ELCoT” a cost-effective single camera 3D tracking system has been developed which enables the detection of arm and head movements of human patients. Amongst others, the measuring system is designed for a new hearing test (based on the “Mainzer Kindertisch”, which analyzes the directional hearing capabilities of children in cooperation with the research project ERKI (Evaluation of acoustic sound source localization for children. As part of the research project framework “Hearing in everyday life (HALLO” a stereo tracking system is being used for analyzing the head movement of human patients during complex acoustic events. Together with the consideration of biosignals like skin conductance the speech comprehension and listening effort of persons with reduced hearing ability, especially in situations with background noise, is evaluated. For both projects the system design, accuracy aspects and results of practical tests are discussed.

    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.

    2016-10-01

    Full Text Available This study focuses on the development of a profiling system to specify the needs of hearing-aid candidates. As a basis for the profile of compensation needs, we used a slightly modified version of the Amsterdam Inventory of Disability and Handicap, combined with the well-known Client-Oriented Scale of Improvement (COSI. The first questionnaire results in scores for six audiological dimensions: detection, speech in quiet, speech in noise, localization, focus or discrimination, and noise tolerance. The goal of this study was to determine whether the six dimensions derived from the disability questionnaire are appropriate to also categorize individual COSI targets. The results show a good agreement between eight audiologists in the categorization of COSI goals along the six dimensions. The results per dimension show that the dimension focus or discrimination can be regarded as superfluous. Possible additional dimensions were tinnitus and listening effort. The results indicate that it is possible to translate individual user needs (administered using COSI into more general dimensions derived from a disability questionnaire. This allows to summarize the compensation needs for individual patients in a profile of general dimensions, based on the degree of disability and the individual user needs. This profile can be used as a starting point in hearing aid selection. This approach also offers a well-structured method for the evaluation of the postfitting results.

    An increased occurrence of major depressive disorder has been reported in tinnitus patients, and of tinnitus in depressive patients. Involvement of several Brodmann areas (BAs) has been reported in tinnitus perception. The aim of this study was to assess the regional cerebral blood flow (rCBF) changes in depressed patients with and without tinnitus. The rCBF distribution at rest was compared among 45 patients with a lifetime prevalence of major depressive disorder, of whom 27 had severe tinnitus, and 26 normal healthy subjects. 99mTc-hexamethylenepropylene amine oxime (99mTc-HMPAO) single photon emission computed tomography (SPECT), using a three-headed gamma camera, was performed and the uptake in 34 functional sub-volumes of the brain bilaterally was assessed by a computerized brain atlas. Decreased rCBF in right frontal lobe BA 45 (Ptinnitus patients compared with non-tinnitus patients. The proportion of tinnitus patients with pronounced rCBF alterations in one or more of the temporal lobe BAs 41+21+22 was increased compared to gender matched controls (Ptinnitus (Ptinnitus patients only in three limbic BAs (Ptinnitus patients only in five BAs subserving auditory perception and processing (Pdepressed patients with and without tinnitus were found in this study. The rCBF alterations were distributed in the cortex and were particularly specific in the auditory cortex. These findings suggest that taking audiological symptoms into account may yield more consistent results between rCBF studies of depression.

    Full Text Available Purpose. Tinnitus and sleep disturbance are prevalent in veterans, and a better understanding of their relationship can help with tinnitus treatment. Materials and Methods. Retrospective chart review of 94 veterans seen in audiology clinic between 2010 and 2013 is presented. Results. The mean age was 62 years, and 93 of 94 veterans were males. The majority (96% had hearing loss. The positive predictive value of the ESS for sleep disorder was 97% and the negative predictive value was 100%. Veterans with a Tinnitus Handicap Inventory (THI score ≥38 had significantly higher Epworth Sleepiness Scale (ESS scores compared to those with THI score <38 (P=0.006. The former had a significantly higher incidence of PTSD, anxiety, and sleep disorder. A subgroup of patients had normal sleep despite rising THI scores. Bilateral tinnitus, vertigo, and anxiety were found to be predictors of sleep disturbance. Conclusions. The ESS can be used as a tool in the initial assessment of sleep disorders in veterans with tinnitus. Higher tinnitus handicap severity is significantly associated with greater sleep disturbance. Optimal management of tinnitus may require concomitant treatment of sleep disorder, PTSD, anxiety, and depression.

    The identification of anxiety and depressive disorders in tinnitus patients is important from a therapeutic point of view. We have addressed this question by investigating the screening performance of the Hospital Anxiety and Depression Scale (HAD) in a consecutive series of tinnitus patients (n = 82) without severe socially disabling hearing loss referred to an audiological clinic. The structured clinical interview for DSM-III criteria was used as the gold standard. Receiver operating characteristic (ROC) curves were used to compare the screening abilities of the HAD subscales for anxiety and depression and the total HAD Scale. The ROC analysis showed that the HAD Scale was better at detecting depression than anxiety disorders in tinnitus patients. The optimal cut-off score for the subscales was > or = 5 when we were screening for any anxiety or depressive disorder as well as for major depression. The performance of the HAD depression subscale was superior, especially when we were screening for major depression only (sensitivity 1.00; specificity 0.75). The findings of the study suggest that the HAD Scale is more useful for screening for depression than for anxiety disorders in tinnitus patients

    Full Text Available Background and Aim: Turner syndrome is the most common sex chromosome abnormality in females, affecting an estimated 3% of all conceiving females. Otologic disease is a common problem in Turner syndrome patients that is due to a combination of small dysfunction Eustachian tube, palatal dysfunction and cochlear malformation.Methods: This study assessed the otologic and audiologic characteristics of a group of Turner syndrome patients. We studied 40 Turner patients aged 10 to 20 years (mean age: 15.84 years, SD=2.67. Pure tone audiometry was carried out for all of them.Results: Forty percent of the patients reported a history of middle ear disease. Analysis of audiometric data in 40 patients tested reveals normal hearing in 47.5%, pure sensorineural hearing loss in 32.5%, pure conductive hearing loss in 17.5% and mixed hearing loss in 2.5% of patients.Conclusion: Careful follow up during early childhood of children with Turner syndrome is necessary to detect middle ear disease and prevent the probable sequel. However, long term periodic follow up is mandatory even after resolution of middle ear disease to detect sensorineural hearing loss

    DFNB4 is non-syndromic, autosomal recessive type of hearing loss with an enlarged vestibular aqueduct (EVA) caused by mutations in SLC26A4/pendrin. Although the characteristics of hearing loss are well known in DFNB4, vestibular function remains inconclusive. We evaluated the vestibular function of 31 patients with bi-allelic mutations in SLC26A4/pendrin and analyzed genetic, radiological, and audiological correlations with vestibular function. In a caloric test, unilateral and bilateral vestibulopathies were detected in 45.2% and 6.4% of patients, respectively; however, only 22.6% had subjective vertigo symptoms. While vestibular phenotype was not significantly associated with specific mutations in genetic alleles or the sizes of the endolymphatic sac and vestibular aqueduct, a residual hearing threshold at a low frequency (500 Hz) was definitely correlated with vestibular function in DFNB4 (p = 0.005). These findings may indicate that vestibular function in DFNB4 deteriorates unilaterally in ears when hearing loss occurs. In conclusion, DFNB4 shows vestibular dysfunction, which is strongly linked to hearing loss at low frequencies without any allelic or anatomical predisposing factor.

    The characteristics of hearing impairment (HI) in rheumatoid arthritis (RA) are still poorly understood, and their association with disease activity is based on conflicting information. This study compared HI between RA patients and controls and between active and remission RA groups using multi-frequency audiometry. This study enrolled 88 RA patients and 50 controls. The pure-tone hearing thresholds at 500 to 4000 Hz for air (AC) and bone (BC) conduction were compared between RA and controls as well as between active and remission RA patients using DAS28-CRP scores. The pure-tone hearing thresholds for AC and BC were significantly higher at high frequencies (2000 and 4000 Hz) in the RA group for both ears compared with controls. In addition, the BC threshold at 1000 Hz for the right ear was higher in the RA group than controls. When active and remission RA patients were compared, the thresholds were higher only at 4000 Hz for both ears for AC and BC in patients with active RA. The air-bone gap differed significantly at 2000 and 4000 Hz in both ears. This study demonstrated that patients with RA have a heightened risk of HI, and disease activity increases this risk, particularly at high frequencies. Clinicians who manage RA should be aware of HI and consider performing audiological evaluations in RA patients with active disease in particular.

    Full Text Available Background and Aim: Auditory neuropathy is an hearing disorder in which peripheral hearing is normal, but the eighth nerve and brainstem are abnormal. By clinical definition, patient with this disorder have normal OAE, but exhibit an absent or severely abnormal ABR. Auditory neuropathy was first reported in the late 1970s as different methods could identify discrepancy between absent ABR and present hearing threshold. Speech understanding difficulties are worse than can be predicted from other tests of hearing function. Auditory neuropathy may also affect vestibular function. Case Report: This article presents electrophysiological and behavioral data from a case of auditory neuropathy in a child with normal hearing after bilirubinemia in a 5 years follow-up. Audiological findings demonstrate remarkable changes after multidisciplinary rehabilitation. Conclusion: auditory neuropathy may involve damage to the inner hair cells-specialized sensory cells in the inner ear that transmit information about sound through the nervous system to the brain. Other causes may include faulty connections between the inner hair cells and the nerve leading from the inner ear to the brain or damage to the nerve itself. People with auditory neuropathy have OAEs response but absent ABR and hearing loss threshold that can be permanent, get worse or get better.

    The recent audiological literature has put forward the hypothesis that children with unilateral hearing loss (UHL) show delays in educational achievement and academic progress and some behavioural difficulties. This motivated us to investigate the long-term effects of monaural auditory deprivation in a group of adults who had suffered from UHL since childhood. A group of subjects, ranging in age from 30 to 55 years, suffering from sensorineural UHL since early childhood, has been examined for psychosocial and psychoacoustical effects and statistically compared with a control group matched for age and sex. We prepared a questionnaire directed to provide some objective and subjective indices of psychosocial disability and handicap. Some questions were directed towards specific aspects of auditory function; others assessed the degree of education and the type of working performed. The results of the investigation confirmed the superiority of binaural v. monaural hearing. This was clearly demonstrated in psycho-acoustical performance in sound localisation, speech recognition in noise, together with the appreciation of music. On the other hand, the parameters concerned with educational, social and employment achievement did not support the existence of any significant difference between binaurally and monaurally hearing subjects. The data obtained in the present study thus do not support the existence of non-auditory, long-term effects of monaural hearing loss.

    Full Text Available Background: Tinnitus is one of the otologic symptoms commonly reported to be associated with temporomandibular disorder (TMD, and questions regarding its nature and cause continue to plague the clinical and research community.Objectives: The current pilot study aimed to investigate the clinical signs and symptoms of presenting tinnitus in a group of individuals with TMD (group A, and compare them with a group with tinnitus but without TMD (group B. Twenty participants were included in the study, 10 from each group.Methods: All participants underwent basic audiological as well as ear, nose and throat (ENT evaluations to establish group A and group B. For tinnitus assessment, all participants completed a tinnitus survey questionnaire, and their tinnitus was evaluated using tinnitus matching procedures.Results: Findings revealed clinically relevant differences in attributes of tinnitus in patients with and without TMD. Most of the participants in group A matched their tinnitus to a 6 000 Hz tone or noise, at lower intensity levels than participants in group B, although these results were not statistically significant. Participants in group A associated their tinnitus with a single sound whereas some participants in group B associated it with more than one sound. More participants in group B reported the duration of their tinnitus as constant.Conclusions: Tinnitus may occur in patients with TMD, and be of high frequency. This highlights the importance of thorough assessment for patients with tinnitus as this might have implications for diagnosis and management.

    Full Text Available Traditionally, audiology research has focused primarily on hearing and related disorders. In recent years, however, growing interest and insight has developed into the interaction of hearing and cognition. This applies to a person’s listening and speech comprehension ability and the neural realization thereof. The present perspective extends this view to oral communication, when two or more people interact in social context. Specifically, the impact of hearing impairment and cognitive changes with age is discussed.In focus are executive functions, a group of top-down processes that guide attention, thought and action according to goals and intentions. The strategic allocation of the limited cognitive processing capacity among concurrent tasks is often effortful, especially under adverse communication conditions and in old age. Working memory, a sub-function extensively discussed in cognitive hearing science, is here put into the context of other executive and cognitive functions required for oral communication and speech comprehension. Finally, taking an ecological view on hearing impairment, activity limitations and participation restrictions are discussed regarding their psycho-social impact and third-party disability.

    Full Text Available Aim: The aim of this study was to evaluate th hearing functions of patients with Sagliker syndrome. Sagliker syndrome is a new disease entity that firstly has been described at year 2000. The frequency of this syndrome has been reported as approximately 0.5% of patient with chronic renal failure and mostly seen in poor and underdeveloped countries. The definite causes of this entity has not been not been clearly understood yet, however studies on risk factors that can lead to this syndrome are underway. Sagliker Syndrome seems to be related to chronic kidney disease and secondary hyperparathyroidism. Every kind of bone abnormalities including, skull deformities, short stature, maxillary and mandibulary changes, teeth abnormalities, soft and harmless tumoral tissues in the mouth and fingertip changes can develop. Psychological problems and depression may accompany these findingsMaterials and Methods: In present study, 12 patients with Sagliker Syndrome were retrospectively evaluated. Audiological tests were performed on these patients, including otoscopic examinations, Rinne and Weber tests, pure tone odiometry and timpanometry. Results: Five patients (41.7% were found to have sensorineural type hearing loss. According to our results with a limited number of patients, hearing loss potential seems to be high with Sagliker Syndrome.Conclusion: Haemodialysis can be suggested as a risk factor on hearing loss of Sagliker syndrome, since all of our patients were on hemodialysis.

    Hearing loss is a common disability in the United States, most frequent among men, elderly individuals, and veterans but is increasingly affecting other younger adults. Types of hearing loss include sensorineural, conductive, and mixed. Hearing loss in children often is related to infections, time spent in a neonatal intensive care unit, and genetic etiologies. Presbycusis (ie, age-related hearing loss) is the most common etiology in adults. Adverse effects of untreated hearing loss include isolation, depression, lower income, and higher unemployment. Hearing aid use reduces levels of disability, cognitive impairment, and psychosocial distress while improving quality of life. At least 75% of individuals with hearing loss are not receiving treatment for it. All infants should be screened for hearing loss, as should children and adults with risk factors. The Joint Commission on Infant Hearing Screening has a 1-3-6 goal for screening: identification by age 1 month, confirmation by age 3 months, and intervention by age 6 months. The presence of an ongoing physician-patient relationship increases the likelihood that a patient will admit to having a hearing loss. Adults can be screened using single-question or standardized instrument screens. All patients with suspected hearing loss should undergo audiometry by an audiology subspecialist.

    Introduction Hearing loss is one of the most common problems in the elderly population. Besides compromising oral communication, it directly affects social relations and prevents elderly patients from living actively in society, possibly leading to the onset of depression or other conditions. Objective To analyze the effects of unilateral adaptation of hearing aids on symptoms of depression and the social activity constraints of elderly subjects with hearing impairment. Methods The sample consisted of elderly subjects with hearing loss who did not use hearing aids. Data were collected in two phases. Initially, all participants underwent an audiological assessment and answered the Hearing Handicap Inventory for Elderly (summarized version) and the Geriatric Depression Scale. All subjects participated in the selection and hearing aid adaptation processes and became monaural hearing aid users. After 30 days of hearing aid use, they were assessed with the same instruments. The results of the questionnaires before and after hearing aid adaptation were compared. Results The sample consisted of 13 individuals, between 60 and 90 years old (mean 72.85 ± 11.05 years). Data analysis showed that there was significant improvement in social activity constraints (p depression (p = 0.031). Conclusion Results show that, in the sample studied, unilateral hearing aid adaptation reduced social activity constraints and depression symptoms.

    There are few accounts of cochlear implantation in adults with post-traumatic sensorineural hearing loss. We report our experience with multichannel implantation in three such patients. Two patients experienced no cognitive or communication deficits as a result of their head injury. At nine months post-implant, compared with our experience of non-head-injured implantees, these patients achieved average or above average scores on audiological performance tests. The third patient presented with cognitive, behavioural and communicative deficits. The level of improvement achieved by this patient, when lip-reading was supplemented with electrical stimulation, in both BKB sentence and connected discourse tracking (CDT) tests was comparable with that of the non-head-injured group. However, his absolute performance at nine months post-implant was well below average. Performance at 18 months on BKB sentences and environmental sound recognition showed little change, and was again well below average, however his score on CDT with lip-reading and electrical stimulation improved considerably and was similar to the average achieved by the non-head-injured group. The major difficulties experienced with this patient were increasing depression and low implant use. Considerably more time was spent in the assessment and rehabilitation of this patient and involved liaison with a number of other agencies. When considering such patients for cochlear implantation it is strongly recommended that these additional requirements are taken into account.

    A growing interest in cognitive effects associated with speech and hearing processes is spreading throughout the scientific community essentially guided by evidence that central and peripheral hearing loss is associated with cognitive decline. For the present research, 125 participants older than 65 years of age (105 with hearing impairment and 20 with normal hearing) were enrolled, divided into 6 groups according to their degree of hearing loss and assessed to determine the effects of the treatment applied. Patients in our research program routinely undergo an extensive audiological and cognitive evaluation protocol providing results from the Digit Span test, Stroop color-word test, Montreal Cognitive Assessment and Geriatric Depression Scale, before and after rehabilitation. Data analysis was performed for a cross-sectional and longitudinal study of the outcomes for the different treatment groups. Each group demonstrated improvement after auditory rehabilitation or training on short- and long-term memory tasks, level of depression and cognitive status scores. Auditory rehabilitation by cochlear implants or hearing aids is effective also among older adults (median age of 74 years) with different degrees of hearing loss, and enables positive improvements in terms of social isolation, depression and cognitive performance.

    Materials and Methods: The present retrospective, study-controlled study investigated 422 ears undergoing COM surgery. The minimum and maximum postoperative follow-up periods were 6 and 48 months, respectively. The study group consisted of patients with cholesteatomatous COM, while the control group included patients with non-cholesteatomatous COM, who had undergone ear surgery.  Postoperative graft success rate and audiological test results were recorded and the effect of cholesteatoma on graft success rate was investigated.  Results: The overall GSR was 92.4%. In the study group (COM with cholesteatoma,the postoperative GSR, mean speech reception threshold improvement, and mean air-bone gap gain were 95.3%, 2.1 dB, and 3.2 dB, respectively. In the control group (COM without cholesteatoma, however, these measurements were 90.9%, 9.4 dB, and 9.1 dB, respectively. The difference between the two groups was not statistically significant.  Conclusion:  The study results suggest that cholesteatoma is not a significant prognostic factor in graft success rate.

  20. Isolated Sensorineural Hearing Loss as a Sequela after Lightning Strike

    Full Text Available In most of the surviving patients after a lightning strike, audiovestibular abnormalities have been reported. The most frequently reported type of abnormalities is a tympanic membrane perforation with hearing loss and external ear canal burn. However a sensor neural hearing loss and mixed type hearing loss can also occur, but these occur rarely. A nineteen-year-old female patient had, after a lightning strike, serious burns on the left ear, behind the ear, and on the chest and neck. She also had in her left ear 108 dB hearing loss with irregular central perforation and in her right ear 52 dB sensorineural hearing loss. There was no hearing loss before the strike. A hearing aid was recommended for the right ear and good care and follow-up were recommended for the left ear. A lightning strike can cause serious audiological damage. Therefore, it is necessary to make a careful audiovestibular evaluation of the patients. Although there exist rarely healed cases from sensorineural hearing loss after lightning strike in literature, in our case hearing loss occurred bilaterally and then it healed unilaterally. This condition is quite rare in literature.

    This study tested prospective models of anxiety and depression following a first time diagnosis of age-related hearing loss, also known as presbycusis, which is one of the most common and disabling health problems in the world. The predictor of interest was cognitive self-consciousness (CSC; Cartwright-Hatton & Wells (1997). Beliefs about worry and intrusions: The Meta-Cognitions Questionnaire and its correlates. Journal of Anxiety Disorders, 11, 276-279.), or the tendency to closely attend to and monitor the content and process of one's own thoughts. Sixty-seven older adults were assessed at a university-based audiology clinic at three timepoints: at the time of diagnosis (T1), six (T2), and 12 months later (T3). Measures of anxiety, depression, and CSC were collected. It was hypothesized that a subset of older adults with hearing loss would report increased CSC at T2. Additionally, the interaction of CSC and anxiety and depression symptoms at T2 was expected to predict significant variance in measures of anxiety and depression at T3, even after baseline levels of distress were controlled in regression models. Finally, it was hypothesized that consistent use of a hearing aid by T3 would act as a palliative to reduce distress in response to hearing loss at T3. Results were partially consistent with hypotheses and point to a new direction in preventing anxiety and depression following a first time diagnosis of presbycusis.

  2. Phosphodiesterase inhibitors for persistent pulmonary hypertension of the newborn: a review.

    2003-12-01

    Persistent pulmonary hypertension of the newborn (PPHN) is a complex syndrome with multiple causes, with an incidence of 0.43-6.8/1,000 live births and a mortality of 10-20%. Survivors have high morbidity in the forms of neurodevelopmental and audiological impairment, cognitive delays, hearing loss, and a high rate of rehospitalization. The optimal approach to the management of PPHN remains controversial. Inhaled nitric oxide (iNO) is currently regarded as the gold standard therapy, but with as many as 30% of cases failing to respond, has not proven to be the single magic bullet. Given the complex pathophysiology of the disease, any such magic bullet is unlikely. A number of recent studies have suggested a role for specific phosphodiesterase (PDE) inhibitors in the management of PPHN. Sildenafil, a specific PDE5 inhibitor, appears the most promising of such agents. We aim to review the current status and limitations of iNO and the potential of PDE inhibitors in the management of PPHN. The reasons why caution is warranted before specific PDE5 inhibitors like sildenafil are labelled as potential magic bullets for PPHN will be discussed. The need for randomized-controlled trials to determine the safety, efficacy, and long-term outcome following treatment with sildenafil in PPHN is emphasized.

    Full Text Available Abstract Background A number of studies have demonstrated that solvents may induce auditory dysfunction. However, there is still little knowledge regarding the main signs and symptoms of solvent-induced hearing loss (SIHL. The aim of this research was to investigate the association between solvent exposure and adverse effects on peripheral and central auditory functioning with a comprehensive audiological test battery. Methods Seventy-two solvent-exposed workers and 72 non-exposed workers were selected to participate in the study. The test battery comprised pure-tone audiometry (PTA, transient evoked otoacoustic emissions (TEOAE, Random Gap Detection (RGD and Hearing-in-Noise test (HINT. Results Solvent-exposed subjects presented with poorer mean test results than non-exposed subjects. A bivariate and multivariate linear regression model analysis was performed. One model for each auditory outcome (PTA, TEOAE, RGD and HINT was independently constructed. For all of the models solvent exposure was significantly associated with the auditory outcome. Age also appeared significantly associated with some auditory outcomes. Conclusions This study provides further evidence of the possible adverse effect of solvents on the peripheral and central auditory functioning. A discussion of these effects and the utility of selected hearing tests to assess SIHL is addressed.

    Hutchinson-Gilford progeria syndrome (HGPS) is an extremely rare, fatal, segmental premature aging syndrome caused by a mutation in LMNA that produces the farnesylated aberrant lamin A protein, progerin. This multisystem disorder causes failure to thrive and accelerated atherosclerosis leading to early death. Farnesyltransferase inhibitors have ameliorated disease phenotypes in preclinical studies. Twenty-five patients with HGPS received the farnesyltransferase inhibitor lonafarnib for a minimum of 2 y. Primary outcome success was predefined as a 50% increase over pretherapy in estimated annual rate of weight gain, or change from pretherapy weight loss to statistically significant on-study weight gain. Nine patients experienced a ≥50% increase, six experienced a ≥50% decrease, and 10 remained stable with respect to rate of weight gain. Secondary outcomes included decreases in arterial pulse wave velocity and carotid artery echodensity and increases in skeletal rigidity and sensorineural hearing within patient subgroups. All patients improved in one or more of these outcomes. Results from this clinical treatment trial for children with HGPS provide preliminary evidence that lonafarnib may improve vascular stiffness, bone structure, and audiological status.

    Chronic tinnitus, the continuous perception of a phantom sound, is a highly prevalent audiological symptom. A promising approach for the treatment of tinnitus is repetitive transcranial magnetic stimulation (rTMS) as this directly affects tinnitus-related brain activity. Several studies indeed show tinnitus relief after rTMS, however effects are moderate and vary strongly across patients. This may be due to a lack of knowledge regarding how rTMS affects oscillatory activity in tinnitus sufferers and which modulations are associated with tinnitus relief. In the present study we examined the effects of five different stimulation protocols (including sham) by measuring tinnitus loudness and tinnitus-related brain activity with Magnetoencephalography before and after rTMS. Changes in oscillatory activity were analysed for the stimulated auditory cortex as well as for the entire brain regarding certain frequency bands of interest (delta, theta, alpha, gamma). In line with the literature the effects of rTMS on tinnitus loudness varied strongly across patients. This variability was also reflected in the rTMS effects on oscillatory activity. Importantly, strong reductions in tinnitus loudness were associated with increases in alpha power in the stimulated auditory cortex, while an unspecific decrease in gamma and alpha power, particularly in left frontal regions, was linked to an increase in tinnitus loudness. The identification of alpha power increase as main correlate for tinnitus reduction sheds further light on the pathophysiology of tinnitus. This will hopefully stimulate the development of more effective therapy approaches. PMID:23390539

    Full Text Available Introduction. Although quarry operations have high economic significance, the effects they cause to the workers in terms of excessive noise production cannot be overlooked. This cross-sectional study assessed the extent of noise exposure and its influence on hearing capabilities among quarry workers in Ashanti region. Methods. The study involved 400 workers randomly selected from five quarries in Ashanti region from April to June 2012. Data was collected using structured questionnaires, physical examination, and audiological assessments. A logistic regression model was fitted to assess independent predictors of hearing loss. Results. All the machines used at the various quarries produced noise that exceeded the minimum threshold with levels ranging from 85.5 dBA to 102.7 dBA. 176 (44% of study respondents had hearing threshold higher than 25 dBA. 18% and 2% of these were moderately (41–55 dBA and severely (71–90 dBA impaired, respectively. Age, duration of work, and use of earplugs independently predicted the development of hearing loss. Use of earplugs showed a protective effect on the development of hearing loss (OR = 0.45; 95% CI = 0.25, 0.84. Conclusion. This study provides empirical evidence on the extent of damage caused to quarry workers as a result of excessive noise exposure. This will support the institution of appropriate protective measures to minimize this threat.

    Full Text Available Introduction: Parkinson disease (PD is a degenerating disease with a deceitful character, impairing the central nervous system and causing biological, psychological and social changes. It shows motor signs and symptoms characterized by trembling, postural instability, rigidity and bradykinesia. Objective: To evaluate the central hearing function in PD patients. Method: A descriptive, prospect and transversal study, in which 10 individuals diagnosed of PD named study group (SG and 10 normally hearing individuals named control group (CG were evaluated, age average of 63.8 and (SD 5.96. Both groups went through otorhinolaryngological and ordinary audiological evaluations, and dichotic test of alternate disyllables (SSW. Results: In the quantitative analysis, CG showed 80% normality on competitive right-ear hearing (RC and 60% on the competitive left-ear hearing (LC in comparison with the SG that presented 70% on RC and 40% on LC. In the qualitative analysis, the biggest percentage of errors was evident in the SG in the order effect. The results showed a difficulty in identifying a sound when there is another competitive sound and in the memory ability. Conclusion: A qualitative and quantitative difference was observed in the SSW test between the evaluated groups, although statistical data does not show significant differences. The importance to evaluate the central hearing process is emphasized when contributing to the procedures to be taken at the therapeutic follow-up.

    Fatigue is common in individuals with a variety of chronic health conditions and can have significant negative effects on quality of life. Although limited in scope, recent work suggests persons with hearing loss may be at increased risk for fatigue, in part due to effortful listening that is exacerbated by their hearing impairment. However, the mechanisms responsible for hearing loss-related fatigue, and the efficacy of audiologic interventions for reducing fatigue, remain unclear. To improve our understanding of hearing loss-related fatigue, as a field it is important to develop a common conceptual understanding of this construct. In this article, the broader fatigue literature is reviewed to identify and describe core constructs, consequences, and methods for assessing fatigue and related constructs. Finally, the current knowledge linking hearing loss and fatigue is described and may be summarized as follows: Hearing impairment may increase the risk of subjective fatigue and vigor deficits; adults with hearing loss require more time to recover from fatigue after work and have more work absences; sustained, effortful, listening can be fatiguing; optimal methods for eliciting and measuring fatigue in persons with hearing loss remain unclear and may vary with listening condition; and amplification may minimize decrements in cognitive processing speed during sustained effortful listening. Future research is needed to develop reliable measurement methods to quantify hearing loss-related fatigue, explore factors responsible for modulating fatigue in people with hearing loss, and identify and evaluate potential interventions for reducing hearing loss-related fatigue.

    Smith-Magenis syndrome (SMS) is a multiple congenital anomaly, mental retardation (MCA/MR) syndrome associated with deletion of chromosome 17 band p11.2. As part of a multi-disciplinary clinical, cytogenetic, and molecular approach to SMS, detailed clinical studies including radiographic neurologic, developmental, ophthalmologic, otolaryngologic, and audiologic evaluations were performed on 27 SMS patients. Significant findings include otolaryngologic abnormalities in 94%, eye abnormalities in 85%, sleep abnormalities (especially reduced REM sleep) in 75%, hearing impairment in 68% (approximately 65% conductive and 35% sensorineural), scoliosis in 65% brain abnormalities (predominantly ventriculomegaly) in 52%, cardiac abnormalities in at least 37%, renal anomalies (especially duplication of the collecting system) in 35%, low thyroxine levels in 29%, low immunoglobulin levels in 23%, and forearm abnormalities in 16%. The measured IQ ranged between 20-78, most patients falling in the moderate range of mental retardation at 40-54, although several patients scored in the mild or borderline range. The frequency of these many abnormalities in SMS suggests that patients should be evaluated thoroughly for associated complications both at the time of diagnosis and at least annually thereafter. 42 refs., 2 figs., 3 tabs.

    Objective First, we review the development and plasticity of the central auditory pathways in infants and children with hearing loss who are fitted with cochlear implants (CIs). Second, we describe case studies demonstrating the clinical utility of the P1 central auditory evoked potential (CAEP) for evaluating cortical auditory maturation in the rapidly increasing number of cochlear-implanted children who have multiple disabilities. Study Design Children who receive CIs provide a platform to examine the trajectories of deprivation-induced and experience-dependent plasticity in the central auditory system. We review the evidence for, and time limits of sensitive periods for cortical auditory maturation framing an optimal period for cochlear implantation. Finally, we evaluate the use of the P1 biomarker as an objective assessment tool in the special case of children with multiple disabilities. Results The P1 response was useful in assessing central auditory maturation in patients with CHARGE association, ANSD, and Pallister-Killian Syndrome concomitant with hearing loss. Conclusion The presence of co-existing disabilities in addition to hearing loss poses unique challenges regarding both pre-intervention evaluation and post-intervention rehabilitation for children with multiple disabilities. When combined with a standard audiological test battery, the P1 CAEP biomarker has a useful role in objectively evaluating the maturation of central auditory pathways to determine the effectiveness of various intervention strategies in hearing-impaired children with multiple disabilities.

    Pallister-Killian syndrome is a rare, multi-system developmental diagnosis typically caused by tetrasomy of chromosome 12p that exhibits tissue-limited mosaicism. The spectrum of clinical manifestations in Pallister-Killian syndrome is wide and includes craniofacial anomalies, clefts, ophthalmologic, audiologic, cardiac, musculoskeletal, diaphragmatic, gastrointestinal, genitourinary, and cutaneous anomalies in association with intellectual disability and seizures. Growth parameters are often normal to elevated at birth with deceleration of growth postnatally. No formal estimate of the prevalence of Pallister-Killian syndrome has been made. Here, we report the clinical findings in 59 individuals with Pallister-Killian syndrome who were ascertained at Pallister-Killian syndrome Foundation family meetings held in the summers of 2006, 2008, 2009, and 2010. In addition, the clinical findings of 152 cases reported in the medical literature were reviewed and compared to the cohort examined here. Several novel clinical characteristics were identified through detailed dysmorphology examinations of this cohort and reassertion of a mild developmental variant is described. This report expands the clinical manifestations of Pallister-Killian syndrome and highlights the variable expressivity of this diagnosis with important implications for diagnosis and counseling.

    The family physician is one of the few individuals from whom families receive feedback about their children's development; this makes early identification of potential delays an important responsibility. The American Academy of Pediatrics recommends formal developmental screening for all children at the 9-, 18-, and 24- and/or 30-month well-child visits as well as developmental surveillance at every office visit through age 5 years. A formal screening measure is recommended, taking into account administration time and cost, characteristics of the patient population (eg, availability of screening tool in numerous languages), and psychometrics (eg, reliability, sensitivity, specificity). In the case of abnormal screening results, family physicians must determine the need for further medical evaluation (eg, by a developmental pediatric subspecialist or a pediatric neurology, genetics, or physiatry subspecialist) and/or further developmental evaluation (eg, by a physical therapy [PT], occupational therapy [OT], speech/language pathology, psychology, or audiology subspecialist). Knowledge of early intervention and early childhood programs is necessary for directing parents to evaluation and treatment sources. In treating patients with developmental delays, family physicians must possess knowledge regarding traditional modalities (eg, speech/language therapy, OT, PT) as well as newer treatments with less research support (eg, gluten-free/casein-free diet, hyperbaric oxygen therapy, neurodevelopmental treatment) that families may consider.

    Full Text Available Aim To investigate differences in vestibular evoked myogenic potentials (VEMP results with patients suffering from vestibular migraine and healthy people, taking into consideration values of threshold and latency of occurrence of the characteristic wave complex, size of amplitude, and interaural amplitude ratio. According to the results, determine the importance and usefulness of VEMP in vestibular migraine diagnostics. Methods A total number of 62 subjects were included in the study, 32 of them belonging to a group of patients suffering from vestibular migraine (VM, while other 30 were in a control group of healthy subjects. Information was collected during the diagnostic evaluation. General and otoneurological history of patients and bedside tests, audiological results, videonystagmography and cervical vestibular evoked myogenic potentials (cVEMP were made. Results There was a difference in an interaural ratio of amplitudes in the experimental and control groups, but it was not found to be clinically significant. By ToneBurst 500 Hz method, the interaural amplitude ratio higher than 35% was measured in 46.97% subjects, while the response was totally unilaterally missing in 28.8% patients. Conclusion Even the sophisticated method as cVEMP does not give the ultimate result confirming the vestibular migraine diagnosis, and neither do other diagnostic methods. cVEMP result can contribute to the completion of full mosaic of vestibular migraine diagnostics.

    Hearing is of utmost importance for normal speech and social development. Even children who have mild or unilateral permanent hearing loss may experience difficulties with understanding speech, as well as problems with educational and psycho-social development. The increasing advantages of middle-ear implant technologies are opening new perspectives for restoring hearing. Active middle-ear implants can be used in children and adolescents with hearing loss. In addition to the well-documented results for improving speech intelligibility and quality of hearing in sensorineural hearing loss active middle-ear implants are now successfully used in patients with conductive and mixed hearing loss. In this article we present a case of successful, single-stage vibroplasty, on the right side with the fixation of the FMT on the stapes and PORP CLiP vibroplasty on the left side in a 6-year-old girl with bilateral mixed hearing loss and multiple dyslalia associated with Franceschetti syndrome (mandibulofacial dysostosis). CT revealed bilateral middle-ear malformations as well as an atretic right and stenotic left external auditory canal. Due to craniofacial dysmorphia airway and (post)operative, management is significantly more difficult in patients with a Franceschetti syndrome which in this case favoured a single-stage bilateral procedure. No intra- or postoperative surgical complications were reported. The middle-ear implants were activated 4 weeks after surgery. In the audiological examination 6 months after surgery, the child showed 100% speech intelligibility with activated implants on each side.

    Newborn hearing screening is currently performed routinely in many regional health-care systems in Spain. Despite the remarkable expansion in newborn hearing screening since 2000, its feasibility and the benefits of early identification and intervention, many major challenges still remain. In this article, the Committee for the Early Detection of Hearing Loss (Comisión para la Detección Precoz de la Hipoacusia, CODEPEH) updates the recommendations that are considered important for the future development of early hearing detection and intervention (EDHI) systems in the following points: 1. Screening protocols: Separate protocols are recommended for NICU (Neonatal Intensive Care Units) and well-infant nurseries. 2. Diagnostic audiology evaluation. Professionals with skills and expertise in evaluating newborn and young infants should provide diagnosis, selection and fitting of amplification devices. 3. Medical evaluation. Risk factors for congenital and acquired hearing loss have been combined in a single list rather than grouped by time of onset. A stepwise diagnostic paradigm is diagnostically more efficient and cost-effective than a simultaneous testing approach. 4. Early intervention and surveillance. All individuals providing services to infants with hearing loss should have specialized training and expertise in the development of audition, speech and language. Regular surveillance should be performed on developmental milestones, auditory skills, parental concerns, and middle ear status. 5. Quality control. Data management as part of an integrated system is important to monitor and improve the quality of EDHI services.

    Full Text Available Background Hearing loss is developing when age is rising. Initiation and progression rates of hearing loss vary among different individuals and groups. Objectives The current study aimed to determine satisfaction of the elderly with their hearing aids in different types of hearing loss and comorbidities. Patients and Methods The study was conducted on 40 elderly subjects suffering from hearing loss and using hearing aids. The data collection method included assessment of hearing loss in addition to using a questionnaire to estimate respondents' satisfaction with their hearing aids in daily life. The Persian version of the Satisfaction with Amplification in Daily Life (SADL questionnaire was administered. The data were analyzed using descriptive and inferential statistics by SPSS software version19. Results The mean satisfaction scores of the elderly were 4.83 ± 0.51 and 5.36 ± 0.30 in the sensorineural loss groups. There was no significant difference between different comorbidities. There was a significant difference between satisfaction level of cost and services subscales in the symmetrical styles of hearing loss (P value = 0.04. Conclusions The findings of the study indicated a high satisfaction of the elderly with their hearing aids, considering the type of hearing loss. Despite all the efforts to improve the audiologic services during verification process, the elderly should be consulted specifically in order to fit their hearing aid as well as their expectations from aid.

  18. On the (unimportance of working memory in speech-in-noise processing for listeners with normal hearing thresholds

    Full Text Available With the advent of cognitive hearing science, increased attention has been given to individual differences in cognitive functioning and their explanatory power in accounting for inter-listener variability in the processing of speech in noise (SiN. The psychological construct that has received much interest in recent years is working memory (WM. Empirical evidence indeed confirms the association between WM capacity (WMC and SiN identification in older hearing-impaired listeners. However, some theoretical models propose that variations in WMC are an important predictor for variations in speech processing abilities in adverse perceptual conditions for all listeners, and this notion has become widely accepted within the field. To assess whether WMC also plays a role when listeners without hearing loss process speech in adverse listening conditions, we surveyed published and unpublished studies in which the Reading-Span test (a widely used measure of WMC was administered in conjunction with a measure of SiN identification, using sentence material routinely used in audiological and hearing research. A meta-analysis revealed that, for young listeners with audiometrically normal hearing, individual variations in WMC are estimated to account for, on average, less than 2% of the variance in SiN identification scores. This result cautions against the (intuitively appealing assumption that individual variations in WMC are predictive of SiN identification independently of the age and hearing status of the listener.

    Full Text Available Giant cell tumor (GCT is classified as a benign bone tumor, and it is frequently identified at the epiphysis of long bones and relatively rare in the temporal bone. For orthopedists expert at recognizing bone and soft tissue tumors, the diagnosis of GCT is relatively easy; however, since head and neck surgeons experience few cases of GCT, it may be difficult to diagnose when it occurs in the temporal bone. A 32-year-old man complained of left hearing loss, aural fullness, and tinnitus. Examination of the ear revealed a bulging tumor. Audiologic examination demonstrated conductive hearing loss of the left ear. Computer tomograph of the temporal bone showed a soft-tissue-density specification indicating bone destruction at the left temporal bone. The tumor invaded the skull base. Imaging examinations using magnetic resonance imaging revealed a nonhomogenous isosignal intensity area on T1 at the left temporal bone. After intravenous gadolinium, the mass showed unequal enhancement. This patient subsequently underwent surgery to remove the lesion using transmastoid and middle fossa approach. Pathological examinations from specimens of the tumor revealed characteristic of GCT. No clinical or radiological evidence of tumor recurrence was detected for 4 years.

    Full Text Available Individual’s hearing performance after cochlear implant (CI is variable and depends on different factors such as etiology of deafness, age at implantation, and social/family hearing environment. Here we report the case of dizygotic twins, boy and girl, presenting with neurosensorial profound deafness prior CI (age of implantation = 3.5 years old. Both parents have severe/profound deafness, since childhood, and use sign language as primary mode of communication. Clinical and genetic characterization was performed, as well as the assessment of the auditory and oral (rehabilitation after CI, applying a battery of audiological, speech, and language tests. The twin girl and the father were homozygous for the c.35delG mutation in the GJB2 gene, while the twin boy and the mother were compound heterozygotes, both monoallelic for c.35delG and for the deletion del(GJB6-D13S1830 in the GJB6 gene. The remaining hearing impaired relatives were c.35delG homozygotes. The genetic cause of deafness was thus identified in this family. Some noteworthy differences were observed regarding twins’ auditory and oral performance after CI. Subsequent follow-up of these children allowed us to conclude that those differences were most likely due to the different environment in which the twins have been living than to their different GJB2/GJB6 genotypes.
