Following the patient’s head movements, these fragments, moving by inertia, incorrectly stimulate the canals generating vertigo. The BPPV is diagnosable by observing the nystagmus that is generated in the patient following the Dix-Hallpike maneuver used for BPPV diagnosis of vertical semi-circular canal, and, following the supine head yaw test used for lateral semi-circular canal. Correctly identifying the origin of this specific peripheral vertigo, would mean to obtain a faster diagnosis and an immediate resolution of the problem for the patient. In this context, this study aims to identify precise training activities, aimed at the application of specific diagnostic maneuverers for algorithm decisions in support of medical personnel. The evaluations reported in this study refer to the data collected in the Emergency Department of the Cardarelli Hospital of Naples. The results obtained, over a six-month observation period, highlighted the advantages of the proposed procedures in terms of costs, time and number of BPPV diagnoses.</p> 2020-07-10T00:00:00+00:00 Copyright (c) 2020 The Authors Upright head roll test: A new contribution for the diagnosis of lateral semicircular canal benign paroxysmal positional vertigo 2020-07-14T09:30:30+00:00 Pasquale Malara Andrea Castellucci Salvatore Martellucci <p>Diagnosing the affected side in Benign Paroxysmal Positional Vertigo (BPPV) involving the Lateral Semicircular Canal (LSC) is often challenging and uncomfortable in patients with recent onset of vertigo and intense autonomic symptoms. The Minimum Stimulus Strategy (MSS) aims to diagnose side and canal involved by BPPV causing as little discomfort as possible to the patient. The strategy applied for LSC-BPPV includes the evaluation of pseudo-spontaneous nystagmus and oculomotor responses to the Head Pitch Test (HPT) in upright position, to the seated-supine test and to the Head Yaw Test (HYT) while supine. Matching data obtained by these tests enables clinicians to diagnose the affected side in LSC-BPPV. The purpose of this preliminary study is to propose a new diagnostic test for LSC-BPPV complimentary to the HPT, the Upright Head Roll Test (UHRT), to easily determine the affected ear and the involved arm in the sitting position and to evaluate its efficiency. Our results suggest that the UHRT can increase the sensitivity of the MSS without resorting to the HYT, thus reducing patient’s discomfort.</p> 2020-07-07T00:00:00+00:00 Copyright (c) 2020 The Authors Analysis of the audiological characteristics and comorbidity in patients with chronic tinnitus 2020-04-14T22:07:19+00:00 Silva Pavaci Federica Tortorella Alessandra Barbara Fioretti Anna Maria Angelone Lino Di Rienzo Businco Maria Lauriello Alberto Eibenstein <p>Tinnitus is defined as <em>perception of a sound without sound stimulation</em>. This study aims to investigate the correlation between chronic tinnitus and the most significant clinical comorbidities and pharmacological treatments. We recruited 130 consecutive outpatients with a tinnitus for least from three months and 100 subjects without tinnitus. All patients had a full medical and audiological evaluation and all filled in Tinnitus Handicap Inventory questionnaire and Khalfa’s Hyperacusis questionnaire. We also analyzed the qualitative variables: audiometry exam, tinnitus characteristics and psychometric questionnaires. Univariate logistic regression was performed to evaluate the associations between the presence of tinnitus and the presence of comorbidities and drug intake. The statistical analysis provided the following results in the group of patients with tinnitus. We obtained an Odds Ratio statistically significant for the following categories taken into consideration: the presence of anxiety and depression, neurological diseases, headache, temporomandibular joint (TMJ) disorders, intake of levothyroxine and proton-pump inhibitor. In this study, we tried to evaluate the audiological characteristics in the subjects affected by chronic tinnitus in order to find a possible correlation with the comorbidities and any drugs intake. We found a statistically significant correlation between tinnitus and comorbidities like anxiety, depression, TMJ disorders, dysthyroidism, headache and levothyroxine and PPI intake.</p> 2019-12-19T16:02:01+00:00 Copyright (c) 2019 Silva Pavaci, Federica Tortorella, Alessandra Barbara Fioretti, Anna Maria Angelone, Lino Di Rienzo Businco, Maria Lauriello, Alberto Eibenstein Computational analysis based on audioprofiles: A new possibility for patient stratification in office-based otology 2020-04-14T22:07:47+00:00 Oren Weininger Athanasia Warnecke Anke Lesinski-Schiedat Thomas Lenarz Stefan Stolle <p>Genetic contribution to progressive hearing loss in adults is underestimated. Established machine learning-based software could offer a rapid supportive tool to stratify patients with progressive hearing loss. A retrospective longitudinal analysis of 141 adult patients presenting with hearing loss was performed. Hearing threshold was measured at least twice 18 months or more apart. Based on the baseline audiogram, hearing thresholds and age were uploaded to AudioGene v4® (Center for Bioinformatics and Computational Biology at The University of Iowa City, IA, USA) to predict the underlying genetic cause of hearing loss and the likely progression of hearing loss. The progression of hearing loss was validated by comparison with the most recent audiogram data of the patients. The most frequently predicted <em>loci</em> were DFNA2B, DFNA9 and DFNA2A. The frequency of <em>loci</em>/genes predicted by AudioGene remains consistent when using the initial or the final audiogram of the patients. In conclusion, machine learning-based software analysis of clinical data might be a useful tool to identify patients at risk for having autosomal dominant hearing loss. With this approach, patients with suspected progressive hearing loss could be subjected to close audiological followup, genetic testing and improved patient counselling.</p> 2019-11-05T12:34:46+00:00 Copyright (c) 2019 The Author(s) Apogeotropic variant of horizontal semicircular canal benign paroxysmal positional vertigo: Where are the particles? 2020-04-14T22:08:14+00:00 Bernardo Faria Ramos Renato Cal Camila Martins Brock Pedro Luiz Mangabeira Albernaz Francisco Zuma e Maia <p>The apogeotropic variant of horizontal semicircular canal benign paroxysmal positional vertigo (HC-BPPV) is attributed to free floating particles in the anterior arm of the lateral semicircular canal – particles attached to the cupula facing the canal or particles attached to the cupula facing the utricle. Zuma e Maia described a new treatment for both canalithiasis of the anterior arm of the horizontal semicircular canal (HC) and cupulolithiasis of the HC. Seventeen patients with apogeotropic HC-BPPV were enrolled and treated with Zuma’s Maneuver. During the repositioning of the particles to the utricule, we observed the direction of the nystagmus evoked in each step of this maneuver in order to know where the otoliths were probably located. Eight patients were diagnosed with canalithiasis of the anterior arm, six patients with cupulolithiasis with the particles facing the canal and three patients with cupulolithiasis with the particles facing the utricle. Our data suggest that we can assume where the otoliths are probably located by observing the pattern of the nystagmus evoked in each step of the Zuma’s Maneuver in patients with apogeotropic HC-BPPV.</p> 2019-08-29T00:00:00+00:00 Copyright (c) 2019 The Author(s) Assessment of cochlear trauma and telemetry measures after cochlear implantation: A comparative study between Nucleus® CI512 and CI532 electrode arrays 2020-04-14T22:08:41+00:00 Domenico Cuda Alessandra Murri <p>The aim of this study was to compare the new Cochlear™ Nucleus® Profile with Slim Modiolar Electrode (CI532, Cochlear Ltd., Sidney, Australia) with the previous Contour Advance® (CI512) implant through postoperative residual hearing (RH) threshold shift and telemetry measurements as indirect measures of cochlear trauma. We compared 21 patients implanted with the CI532 and 20 patients implanted with the CI512, matching the 2 groups for age and for hearing loss etiology. All subjects received audiological pure tone average (PTA) calculation pre- and postimplant. Electrode impedance was measured, followed by AutoNRT® to measure and evaluate the Neural Response Telemetry (NRT®) thresholds. Telemetry recordings were made intraoperatively, one month after surgery and one month after activation. The NRT-Ratio was calculated to evaluate full <em>scala tympani</em> (ST) insertion. The results showed a higher number of patients with preserved measurable hearing with the CI532 (10/15; P&gt;0.05) compared to the CI512 (5/14; P&lt;0.05). A significant difference in post-operative low frequency PTA was observed between the two groups. There were no significant differences for telemetry measurements and NRTRatio evaluation of full ST insertion (CI512: 81%; CI532: 95%). A significantly higher number of patients who preserved measurable hearing with the CI532, and a significantly higher post-operative low frequency PTA threshold compared with the CI512 confirmed better RH preservation and lower apical cochlear damage with the CI532. There was a high number of full ST insertions for both electrode arrays. Future studies should investigate the audiological effect of implantation in patients with higher levels of RH, correlating the results with the scalar position, to assess any lesser trauma of the CI532.</p> 2019-07-11T15:22:17+00:00 Copyright (c) 2019 Domenico Cuda, Alessandra Murri Tinnitus and suicide: An unresolved relation 2020-04-14T22:09:08+00:00 Annett Szibor Antti Mäkitie Antti A. Aarnisalo <p>Tinnitus is an auditory phantom sensation which can be a devastating condition for the affected person causing annoyance and discomfort. It may be associated with psychiatric conditions. Patients with highly annoying tinnitus and different comorbidities may have a higher risk of expressing suicidal behaviour and ideation. We aimed to review available reports on the prevalence of suicide and suicidal behaviour with tinnitus patients in order to collate current concepts and to identify possible alarming signs and risk factors. A comprehensive search for appropriate studies listed in PubMed, Ovid and Cochrane databases was conducted using appropriate keyword combinations. We identified 22 publications including original articles, case reports and reviews of which 10 fit our stringent search criteria. Most importantly, from the present studies it appears not feasible to univocally conclude on the co-incidence of tinnitus and suicide. This is due to methodological differences in these approaches, complex interrelations between tinnitus and other psychiatric comorbidities and confounding factors such as the inclusion of patients suffering from post-traumatic stress disorder. More concerted actions involving different medical disciplines are needed to reflect the ethiological heterogeneity of tinnitus and suicide or suicidal behaviour to test for a relationship.</p> 2019-06-07T11:17:18+00:00 Copyright (c) 2019 Annett Szibor, Antti Mäkitie, Antti A. Aarnisalo Effectiveness and efficiency of a dedicated bimodal fitting formula 2020-04-14T22:09:35+00:00 Domenico Cuda Alessandra Murri Anna Mainardi Josef Chalupper <p>The population of unilateral cochlear implant (CI) users with aidable residual hearing in the contralateral ear is continuously growing. Aiding the contralateral ear with a hearing aid has been shown to provide substantial benefit regarding speech intelligibility in quiet and in noise, sound quality, localization ability and listening effort. In this study, a dedicated hearing aid with the accompanying fitting prescription, tailored to the needs of bimodal listeners was evaluated in nine bimodal CI users. Speech intelligibility scores in noise revealed on-par performance of the dedicated bimodal fitting compared to the clinical standard prescription. 78% of the bimodal CI users preferred the dedicated bimodal fitting over the clinical standard. The minimal subject-specific finetuning effort required during the dedicated bimodal fitting process emphasizes the clinical efficiency.</p> 2019-05-09T11:47:00+00:00 Copyright (c) 2019 Domenico Cuda, Alessandra Murri, Anna Mainardi, Josef Chalupper Vocalization frequency as a prognostic marker of language development following early cochlear implantation 2020-04-14T22:10:02+00:00 Paris Binos Elena Loizou <p>Despite their potential significance for later linguistic outcomes, early aspects of vocalization had been seriously undervalued in the past, and thus, minimally investigated until relatively recently. The present article sets out to critically examine existing evidence to: i) ascertain whether vocalization frequency (volubility) posits a plausible marker of cochlear implantation success in infancy, and ii) determine the clinical usefulness of post-implementation vocalization frequency data in predicting later language development. Only recent peer-reviewed articles with substantial impact on vocalization growth during the first year of life, examining sound production characteristics of normally hearing (NH) and hearing impaired infants fitted with cochlear implantation (CI) were mentioned. Recorded differences in linguistic performance among NH and CI infants are typically attributed to auditory deprivation. Infants who have undergone late CI, produce fewer syllables (low volubility) and exhibit late-onset babbling, especially those who received their CIs at the age of 12 months or thereafter. Contrarily, early recipients (before the 12-month of age) exhibit higher volubility (more vocalizations), triggered from CI-initiated auditory feedback. In other words, early CI provides infants with early auditory access to speech sounds, leading to advanced forms of babbling and increased post-implementation vocalization frequency. Current findings suggest vocalization frequency as a plausible criterion of the success of early CI. It is argued that vocalization frequency predicts language development and affects habilitation therapy.</p> 2019-05-06T11:31:34+00:00 Copyright (c) 2019 Paris Binos, Elena Loizou Free-field evoked auditory brainstem responses in cochlear implant users 2020-04-14T22:10:30+00:00 Erik Schebsdat Manuel C. Kohl Farah I. Corona-Strauss Harald Seidler Daniel J. Strauss <p>The importance of binaural cues in auditory stream formation and sound source segregation is widely accepted. When treating one ear with a cochlear implant (CI) the peripheral auditory system gets partially replaced and processing delays get added potentially, thus important interaural time differences get altered. However, these effects are not fully understood, leaving a lack of systematic binaural fitting strategies with respect to an optimal binaural fusion. To get new insights into such alterations, we suggest a novel method of free-field auditory brainstem evoked responses (ABRs) analysis in CI users. This method does not bypass the technically induced intrinsic delays of the sound processor while leaving the whole electrode array active, thus the most natural way of stimulation is provided. We compared the ABRs collected of 12 CI users and 12 normal hearing listeners using two different stimuli (chirp, click) at four different intensities each. We analyzed the ABRs using the average of 2000 trials as well as a single trial analysis and found consistent results in the ABRs’ amplitudes and latencies, as well as in single trial relationships between both groups. This method provides a new perspective into the natural CI users’ ABRs and can be useful in future research regarding binaural interaction and fusion.</p> 2018-12-07T09:20:46+00:00 Copyright (c) 2018 Erik Schebsdat, Manuel C.
