Abstract (sommario):

The article highlights the features of the conduct and interpretation of data on audiological tests at the children in order to identify the degree, type and level of damage of the auditory disorders. According to a survey of 121 children with a diagnosis of sensorineural hearing loss, it was confirmed that using a complex algorithm of audiological tests such as OAE, DPOAE, BERA and ASSR in hearing diagnosis of the children allows to obtain more accurate and detailed information and avoid possible errors in determining various forms of hearing disorders.

Abstract (sommario):

Practical relevance: Auditory function is a sense that is central to life for cats - being important in situational awareness of potential predators, pursuit of prey, and for communication with conspecifics, humans and other species. Deafness in cats is most frequently the result of a genetic disorder, strongly associated with white fur and blue eyes, but may also result from acquired causes such as advancing age, ototoxic drugs, infection, environmental noise and physical trauma. Deafness can be sensorineural, where there is loss of cochlear hair cells, or conductive, where sound is muffled on its way to the inner ear. Clinical challenges: Establishing whether a cat is deaf can be difficult as behavioral testing of hearing is subjective and does not reliably detect unilateral deafness. Brainstem auditory evoked response testing is an objective measure but is limited in its availability. Currently, sensorineural deafness is irreversible because no treatments are available to restore lost hair cells. Conductive hearing loss can usually be treated, although full hearing recovery following otitis media may take weeks as the body clears the middle ear of debris. Evidence base: The author draws on the published literature and his extensive research on clinical aspects and molecular genetics of deafness, principally in companion animals, to review types and forms of deafness in cats. He also discusses current diagnostic approaches and provides brief advice for managing cats with hearing loss.

Abstract (sommario):

Purpose In the field of audiology, auditory processing disorder (APD) continues to be a topic of ongoing debate for clinicians and scientists alike, both in terms of theory and clinical practice. In the current viewpoint, we first lay out the main issues that are central to the controversy surrounding APD, and then suggest a framework toward their resolution. Method The current viewpoint is informed by reviewing existing studies in the field of APD to better understand the issues contributing to the controversies in APD. Results We found that, within the current definition of APD, the two main issues that make the APD diagnosis controversial are (a) comorbidity with other disorders and (b) the lack of domain specificity. These issues remain unresolved, especially with the use of the existing behavioral APD test batteries. In this viewpoint, we shed light on how they can be mitigated by implementing the administration of an objective, physiological test battery. Conclusions By administering an objective test battery, as proposed in this viewpoint, we believe that it will be possible to achieve a higher degree of specificity to the auditory domain that will not only contribute towards clinical practice but also contribute towards strengthening APD as a theoretical construct.

Abstract (sommario):

Objective This study was aimed to determine the role of clinical presentation and tumor characteristics in vestibular schwannoma (VS) at diagnosis, initially treated with conservative management. Design The study was designed as a retrospective chart review. Setting The study was prepared at national tertiary referral center for VS patients. Participants A total of 836 VS patients, initially treated conservatively, were included. Main Outcome Measures Patient characteristics: age at diagnosis, gender, frequency, and duration of, hearing loss, tinnitus, balance disorder (unsteadiness, dizziness, and vertigo), respectively; and tumor characteristics: laterality, growth, cystic component, and location were analyzed in relation to tumor size at diagnosis and change in treatment strategy. Results In total, 169 (20%) patients had a change in treatment strategy. Factors at diagnosis that had a high influence on intervention were a short duration of hearing loss (hazard ratio [HR]: 4.8, p < 0.001) and cystic tumors (HR = 2.6, p < 0.001). Balance disorders and extracanalicular (EC) tumor location have a medium influence on intervention (HR = 1.6, p < 0.01). Tumour growth was seen in 55% of the intervention group; we found a significant correlation with a short duration of hearing loss. Cystic VS was significantly higher between the medium and large tumors, 24.3% and 38.1%. (p = 0.001), respectively. Conclusions Patients with a short duration of hearing loss, balance disorders, EC located tumors, and cystic tumors have a significantly higher chance of a change in treatment strategy. Large tumor size at diagnosis and a cystic component were related to age > 65 years at diagnosis.

Abstract: Sufficient hearing is the cornerstone of the development of children’s complex sensory perception, sound recognition, speech development and optimal communication skills. Hearing screening of newborns is necessary to detect congenital hearing disorders. Compulsory objective hearing screening in Hungary is a significant improvement in early diagnosis. The Audiological Department of Otorhinolaryngology, Head and Neck Surgery Clinic at Semmelweis University serves as a verification center for children identified via the compulsory objective newborn hearing screening and necessitates more detailed assessment. The goal of this study was to summarize the verification results of the year 2018. Case history, ENT examination, electric response measurement, impedance tests, otoacoustic emission measurement, surdopedagogical examination, and genetic examination are the basics of the diagnosis and the therapy as well. Altogether 261 newborns were examined in 2018 and 164 were subjected to audiological tests during the analyzed seven-month period. Normal hearing was detected in both ears in 77% of the cases, while hearing loss has been verified in 37 patients (23% of cases). Permanent hearing loss has been diagnosed in 19 cases, 4 unilateral and 15 bilateral. Hearing loss of sensorineural origin was confirmed in 17, conductive in 2 children. Temporary hearing loss caused by otitis media with effusion was found in further 18 children which healed spontaneously in most cases. Organized neonatal objective hearing examination has been established in Hungary in 2015. As a result, we can diagnose and provide care for children with hearing loss at the earliest stage. The National Newborn Hearing Screening Registry ensures a well-coordinated and smooth process. Orv Hetil. 2019; 160(47): 1850–1855.

Abstract (sommario):

Objective. Tinnitus is frequently associated with temporomandibular joint (TMJ) dysfunction. However, the nature of the relationship is not fully understood. Here the authors compared 30 patients with a confirmed diagnosis of temporomandibular joint dysfunction and tinnitus to a group of 61 patients with tinnitus but without any subjective complaints of TMJ dysfunction with respect to clinical and demographic characteristics. Study Design. Case-control study. Setting. Tertiary referral center. Subjects. Tinnitus patients with and without TMJ dysfunction presenting at the Department of Prosthetic Dentistry and the Tinnitus Clinic at the University of Regensburg. Results. Tinnitus patients with TMJ disorder had better hearing function ( P < .0005), lower age ( P = .001), and lower age at tinnitus onset ( P = .002) and were more frequently female ( P = .003). Their subjectively perceived tinnitus loudness was lower ( P = .01), and more of them could modulate their tinnitus by jaw or neck movements ( P = .001). Conclusion. Classical risk factors for tinnitus (age, male gender, hearing loss) are less relevant in tinnitus patients with TMJ disorder, suggesting a causal role of TMJ pathology in the generation and maintenance of tinnitus. Based on this finding, treatment of TMJ disorder may represent a causally oriented treatment strategy for tinnitus.

Abstract (sommario):

As with any other clinical discipline, otorhinolaryngology uses both simple investigation methods including external examination of ENT organs with an otoscope, rhinoscope and laryngoscope, and more complex ones requiring the use of special devices and equipment. The latter include X-ray examination, US diagnostics, endomicroscopy of the nose and paranasal sinuses, CT and MRI (in case the study of soft tissue formations is needed). To study the auditory analyser functions and the labyrinth state, a number of functional tests are performed including stabilometry or postulography. Audiometry is performed with electroacoustic instruments and can be subjective and objective. Impedancometry, a method of objective hearing assessment, based on measuring the acoustic resistance of a soundconducting device, is used to determine the location and nature of the auditory system disorders. All these methods help establish the correct diagnosis, clarify the localisation of the pathological process and prescribe the correct treatment.

Abstract (sommario):

Enlarged vestibular aqueduct (EVA) syndrome is a common congenital inner ear malformation characterized by a vestibular aqueduct with a diameter larger than 1.5 mm, mixed or sensorineural hearing loss that ranges from mild to profound, and vestibular disorders that may be present with a range from mild imbalance to episodic objective vertigo. In our study, we present the case of a patient with unilateral enlarged vestibular aqueduct and bilateral endolymphatic hydrops (EH). EH was confirmed through anamnestic history and audiological exams; EVA was diagnosed using high-resolution CT scans and MRI images. Therapy included intratympanic infusion of corticosteroids with a significant hearing improvement, more evident in the ear contralateral to EVA. Although most probably unrelated, EVA and EH may present with similar symptoms and therefore the diagnostic workup should always include the proper steps to perform a correct diagnosis. Association between progression of hearing loss and head trauma in patients with a diagnosis of EVA syndrome is still uncertain; however, these individuals should be advised to avoid activities that increase intracranial pressure to prevent further hearing deterioration. Intratympanic treatment with steroids is a safe and well-tolerated procedure that has demonstrated its efficacy in hearing, tinnitus, and vertigo control in EH.

Abstract (sommario):

Infantile hemiparesis may be associated with significant morbidity and may have a profound impact on a child’s physical and social development. Infantile hemiparesis is associated with motor dysfunction as well as additional neurologic impairments, including sensory loss, mental retardation, epilepsy, and vision, hearing, or speech impairments. The objective of this study was to analyze the association between the cause of infantile hemiparesis and birth (gestational age), age of diagnosis, and associated disorders present in children with infantile hemiparesis aged 0 to 3 years. An observational and cross-sectional study was performed. A simple and anonymous questionnaire was created ad hoc for parents of children diagnosed with infantile hemiparesis aged between 0 and 3 years about the situation regarding the diagnosis of hemiparesis, birth, cause of hemiparesis, and presence of other associated disorders. Perinatal stroke (60.1%) was the most common cause of hemiparesis, and the most typical associated disorder was epilepsy (34.2%), with the second largest percentage in this dimension corresponding to an absence of associated disorders (20.7%). The most frequent birth was “no premature” (74.1%). The mean age of diagnosis of infantile hemiparesis was registered at 8 months (IQR: 0–36). Knowing the possible association between different conditioning factors and the cause of infantile hemiparesis facilitates the prevention of severe sequelae in children and family, implementing an early comprehensive therapeutic approach in children with infantile hemiparesis.

Objective This literature review and meta-analysis was performed to evaluate the correlations among hearing and vestibular clinical symptoms, temporal bone findings, and pathological mechanisms in patients with systemic lupus erythematosus (SLE). Study design Relevant papers in the literature were retrospectively reviewed. Clinical hearing aspects in patients with SLE and relevant temporal bone studies in the same field were analyzed. Methods PubMed and Google Scholar searches were performed using the following keywords: “auto-immune disease,” “systemic lupus erythematosus (SLE),” “hearing loss,” “temporal bone study,” “vertigo,” “dizziness,” “tinnitus,” “ear symptoms,” “treatment,” “diagnosis,” “symptoms,” “etiopathogenesis,” “Wegener granulomatosis,” “Sjogren,” “polyarteritis nodosa,” “Cogan syndrome,” and “granulomatosis.” Also included were reviews in which the following terms were present: “SLE,” “temporal bone,” and “hearing symptoms.” Review and conclusion This literature review and meta-analysis focused on the pathological mechanisms through which SLE can damage inner ear structures and determinate hearing and vestibular symptoms. The main mechanisms involved in inner ear damage include the autoimmune response, deposition of immune complexes in the vessels and, to a lesser extent, cytotoxic damage.

Abstract (sommario):

[Truncated abstract] The present study investigated whether any of the characteristics of the compound action potential (CAP) waveform or the spectrum of the neural noise (SNN) recorded from the cochlea, could be used to examine abnormal spike generation in the type I primary afferent neurones, possibly due to pathologies leading to abnormal hearing such as tinnitus or tone decay. It was initially hypothesised that the CAP waveform and SNN contained components produced by the local action currents generated at the peripheral ends of the type I primary afferent neurones, and that changes in these local action currents occurred due to changes in the membrane potential of these neurones. It was further hypothesised that the lateral olivo-cochlear system (LOCS) efferent neurones regulate the membrane potential of the primary afferent dendrites to maintain normal action potential generation, where instability in the membrane potential might lead to abnormal primary afferent firing, and possibly one form of tinnitus. We had hoped that the activity of the LOCS efferent neurones could be observed through secondary changes in the CAP waveform and SNN, resulting from changes in the membrane potential of the primary afferent neurones. The origins of the neural activity generating the CAP waveform and SNN peaks, and the effects of the LOCS on the CAP and SNN were experimentally investigated in guinea pigs using lesions in the auditory system, transient ischemia and asphyxia, focal and systemic temperature changes, and pharmacological manipulations of different regions along the auditory pathway. ... Therefore, the CAP and SNN are altered by changes in the propagation of the action potential along the primary afferent neurones, by changes in the morphology of the tissues surrounding the cochlear nerve, and by changes in the time course of the action currents. If the CAP waveform is not altered, the amplitude of the 1kHz speak in the spontaneous SNN can be used as an objective measure of the spontaneous firing rate of the cochlear neurones. However, because the SNN contains a complex mixture of neural activity from all cochlear neurones, and the amplitude of the spontaneous SNN is variable, it would be difficult to use the spontaneous SNN alone as a differential diagnostic test of cochlear nerve pathologies. To record extratympanic electrocochleography (ET ECochG) from humans, a custom-designed, inexpensive, low-noise, optically isolated biological amplifier was built. Furthermore, a custom-designed extratympanic active electrode and ear canal indifferent electrode were designed, which increased the signal-to-noise ratio of the ECochG recording by a factor of 2, decreasing the overall recording time by 75%. The human and guinea pig CAP waveforms recorded in the present study appeared similar, suggesting that the origins of the human and guinea pig CAP waveforms were the same, and that experimental manipulations of the guinea pig CAP waveform can be used to diagnose the cause of abnormal human ECochG waveforms in cases of cochlear nerve pathologies.

Abstract (sommario):

Introduction

Les surdités cochléaires induisent, outre une audibilité réduite, une série de distorsions de la représentation neurale des sons. Deux des mécanismes à la base de ces distorsions sont d’une part une atteinte de la sélectivité fréquentielle et d’autre part des zones neuro-épithéliales non fonctionnelles. Tant le premier que le second mécanisme apparaissent dans une proportion variable et non prédictible d’un sujet à un autre. Deux tests permettent le diagnostic de ces atteintes spécifiques: la Courbe d’Accord (Tuning Curve: TC) et le Threshold Equalising Noise (TEN) test. La TC, mesurée par une technique psychoacoustique chez un adulte collaborant (Psychophysical TC: PTC), consiste en la mesure du niveau de bruit (masqueur) nécessaire pour masquer un son pur (signal) de fréquence et d’intensité fixes. Le TEN test consiste en la mesure des seuils auditifs dans le silence et en présence d’un bruit égalisateur de seuil (TEN). Ces tests qui requièrent des capacités cognitives adultes normales, ne sont pas applicables aux populations pédiatriques prélinguales.

Ce travail de thèse avait pour but le développement d’un équivalent objectif et non invasif des TCs et du TEN test applicable aux populations pédiatriques. La méthode objective choisie fut les potentiels auditifs stationnaires ou ASSEPs (Auditory Steady State Evoked Potentials). Les ASSEPs sont une réponse électrophysiologique cérébrale évoquée par un stimulus acoustique de longue durée modulé en amplitude et/ou en fréquence.

Méthodes & Résultats

Etape 1

Les développements méthodologiques ont été réalisés sur l’espèce canine et humaine adulte. Les ASSEPs n’ayant jamais été préalablement enregistrés chez le chien, une première étape à consister à définir chez cette espèce les paramètres d’enregistrement optimaux (modulation en amplitude optimale) dont on sait qu’ils interagissent avec l’état veille-sommeil, avec la fréquence testée et probablement avec l’espèce animale investiguée.

A cette fin, les seuils auditifs obtenus chez 32 chiens à l’aide des ASSEPs ont été validés à cinq fréquences audiométriques par comparaison aux seuils obtenus avec les potentiels auditifs du tronc cérébral évoqués aux bouffées tonales.

Les seuils obtenus aux ASSEPs avec les paramètres optimaux d’enregistrement (légèrement différents des paramètres optimaux humains) étaient similaires à ceux obtenus aux bouffées tonales.

Ces résultats ont été publiés dans Clinical Neurophysiology (Markessis et al. 2006; 117: 1760-1771).

Etape 2

La possibilité de mesurer des TCs à l’aide des ASSEPs (ASSEP-TCs) a été évaluée sur 10 chiens. Les données canines ont été comparées à des données de la littérature, çàd aux TC enregistrées chez d’autres espèces et avec d’autres méthodes. Des ASSEP-TCs ont également été enregistrées chez 7 humains adultes et confrontées aux PTCs obtenues chez les mêmes sujets. Les PTCs sont typiquement energistrées avec un signal sinusoïdal alors que le stimulus utilisé pour évoquer un ASSEP est une sinusoïde modulée en amplitude. L’effet des sinusoïdes modulées en amplitude sur les paramètres qualitatifs et quantitatifs des TCs a donc été évalué en comparant les PTCs obtenues avec un son pur et avec un son pur modulé en amplitude chez 10 humains adultes.

Les résultats ont révélé que les ASSEP-TCs enregistrées chez le chien et l’humain présentaient des paramètres qualitatifs et quantitatifs similaires respectivement à ceux décrits dans la littérature et aux PTCs. Par ailleurs, auncun effet des stimuli modulés en amplitude sur les paramètres des PTCs n’a été démontré.

Ces données ont été publiées dans Ear & Hearing (Markessis et al. 2009, 30: 43-53).

Etape 3

Les ASSEP-TCs ont été validées chez 10 chiens en comparant les données aux TC enregistrées par électrocochléographie (Compound Action Potential TC: CAP-TC). Le masqueur utilisé pour les CAP-TCs est typiquement une sinusoïde alors que le masqueur utilisé pour les ASSEP-TCs est un bruit à bande étroite. Dès lors, une comparaison du type de masqueur (sinusoïde vs bruit à bande étroite) sur les paramètres des CAP-TCs et ASSEP-TCs a été réalisée chez 10 chiens.

Les ASSEP-TCs chez le chien se sont révélées qualitativement et quantitativement similaires aux CAP-TCs quel que soit le type de masqueur. Elles presentaient par ailleurs l’avantage d’être moins variables, plus précises et non invasives par rapport aux CAP-TCs.

Ces données ont été publiées dans International Journal of Audiology (Markessis et al. 2010, 49 ;455-62).

Etape 4

Afin d’étudier la validité de la procédure à mettre en évidence des changements de sélectivité fréquentielle dus à une atteinte cochléaire, des ASSEP-TCs ont été obtenues chez 10 chiens cochléo-lésés suite à un trauma acoustique. Les Produits de Distorsion Acoustiques, les potentiels évoqués auditifs du tronc cérébral évoqués par un clic et les ASSEPs à cinq fréquences audiométriques ont été enregisrés afin de délimiter l’étendue de la lésion.

Les ASSEP-TCs ont été fortement altérées, mais pas comme attendu ni suggéré par les mesures fonctionnelles indiquant que le trauma acoustique a créé une lésion différente de celle espérée.

Cette étude doit être poursuivie, des lésions moins importantes créées et une validation histopathologique réalisée.

Etape 5

Le TEN test a été mesuré à l’aide des ASSEPs (ASSEP-TEN) chez 12 adultes et cinq enfants normo-entendants. Les données adultes ont été confrontées aux données comportementales. L’effet des stimuli ASSEP (son pur modulé en amplitude) sur les TEN test a également été investigué en comparant les données comportementales obtenues avec une sinusoïde et avec une sinusoïde modulée en amplitude chez 24 adultes.

Les seuils masqués enregistrés aux ASSEPs étaient supérieurs à ceux mesurés par une épreuve comportementale. L’élévation des seuils masqués pose un problème potentiel de dynamique.

La procédure doit être testée chez des patients présentant une surdité cochléaire attendu que la différence entre les seuils auditifs mesurés aux ASSEPs et par une épreuve comportementale est moindre dans cette population. Dans la mesure où le problème de dynamique résiduelle persiste chez les patients malentendants, d’autres stimuli ou algorithmes d’enregistrement doivent être utilisés.

Etape 6

Le TEN est un stimulus large bande. Il peut dès lors se révéler intolérable chez des patients présentant une atteinte auditive restreinte à une region fréquentielle. L’effet du filtrage du TEN sur les seuils et la sonie du TEN a été étudié chez 24 sujets normo-entendants et 35 patients présentant une perte cochléaire dans les hautes fréquences.

Le filtrage passe-haut du TEN s’est avéré être une solution satisfaisante.

Ces données ont été publiées dans International Journal of Audiology (Markessis et al. 2006; 45: 91-98).

Etape 7

L’effet de l’intensité du TEN sur le diagnostic des zones neuro-épithéliales non fonctionnelles a été investigué chez 24 patients en mesurant les seuils masqués à quatre intensités de TEN différentes. La fiabilité du TEN test a également été évaluée.

Le TEN est une procédure fiable. L’intensité du TEN a affecté le diagnostic chez cinq patients. Ce résultat est interprété en termes de degré de l’atteinte du complexe neurosensoriel.

Ces données ont été publiées dans International Journal of Audiology (Markessis et al. 2009; 48: 55-62).

Conclusion

Un algorithme permettant la mesure de TC et du TEN test objective à l’aide des ASSEPs a été développé. L’implémentation clinique de l’algorithme appliqué à l’enregistrement des CA paraît envisageable. Une importante étape de la corrélation entre modifications anatomiques (à l’aide de l’histopathologie) et physiologiques (ASSEP-TC et CAP-TC) est maintenant celle qui s’impose. Les données préliminaires obtenues sur le TEN test électrophysiologique chez des sujets normo-entendants suggèrent que son implémentation clinique puisse se heurter à un problème de dynamique si ce dernier est confirmé en présence de surdités cochléaires. Plusieurs pistes potentielles de solutions ont été avancées.

Abstract (sommario):

Among complications associated with non-syndromic cleft lip and/or palate (NSCL/P) in school age children, conductive hearing loss has been thoroughly investigated because the symptoms are noticeable and the treatment is often easy to access. Research on central auditory processing disorder [(C)APD] has been rarely explored in this clinical population. However, children with NSCL/P have been reported to have delayed speech and language development, as well as poor academic performance in general compared to craniofacially normal peers, despite their peripheral hearing problems typically resolving with age. In order to investigate suspected (C)APD in children with NSCL/P, the present research program was initiated. The study aimed to utilize a comprehensive test battery to assess auditory status in children with NSCL/P, and to investigate whether they have a greater frequency of (C)APD compared to craniofacially normal children. 147 children with NSCL/P and 60 normal children were recruited. They were Mandarin speakers and attending regular schools. The children with NSCL/P did not have peripheral hearing problems at time of assessment. There were three types of assessment tools used in the present research program. Firstly, hearing health tests were conducted to evaluate peripheral hearing function. Case history and auditory questionnaire reports were completed by caregivers to obtain basic medical and developmental information (Chapter 3). Secondly, auditory behavioral tests of (C)APD functioning were administered, including a gap detection test and a speech in noise recognition test (Chapter 4). Thirdly, an auditory evoked potential (AEP) assessment was conducted as an objective evaluation of the central auditory nervous system (Chapter 5). Based on the results of this research program, it was concluded that, firstly, children with NSCL/P showed behaviors typically found in children with (C)APD when questionnaire results were considered. Children with cleft palate (CP) showed the most negative outcomes, and cleft lip (CL) group children showed results equivalent to craniofacially normal children. Secondly, behavioral assessment results showed that compared to control group children, maturation for temporal resolution abilities was delayed in children with NSCL/P. Also, the ability to use interaural timing and intensity cues for speech recognition in a noisy environment was poorer in children with CP and CLP. Finally, abnormal AEP findings in children with cleft suggested longer neural transmission times and delayed development of the auditory nervous system may occur in this population. In summary, the research program found that children with NSCL/P are at higher risk of auditory processing difficulties compared to craniofacially normal children. In addition, a comprehensive test battery is more appropriate for making an accurate diagnosis of (C)APD in this population than a single assessment protocol. The present research program has contributed to an enhanced awareness of potential (C)APD in children with NSCL/P, which had not been investigated using a comprehensive test battery for a large sample of children with cleft disorders in any previous studies. Since Chinese language specific assessment tools are limited, further studies to develop an appropriate, comprehensive test battery for the diagnosis of auditory processing disorder in Chinese children with oral cleft and to explore effective management of this disorder are required.

Abstract (sommario):

The purpose of the study was to evaluate the sensitivity of the CID Everyday sentences, with competing cafeteria noise, as a measure of the real life receptive communication difficulty experienced by subjects with hearing loss limited to frequencies above 2000 Hz. In order to establish normative data the speech discrimination test w~s given to 38 normal hearing subjects (aged 19-46). Second, the discrimination test was given to 12 hearing impaired subjects (29-64), who also completed a self-assessment questionnaire, the Hearing Handicap Inventory for Adults (HHIA). The results were analyzed to determine: (a) if there was a significant difference between the mean scores of the normal hearing and the hearing impaired subjects, and (b) if there was a significant correlation between the hearing impaired subjects' scores on the discrimination test and those obtained on the HHIA. The investigation revealed that a statistically significant difference (p=0.04) existed between the mean scores of the two subject groups on the discrimination test. The hearing impaired subjects averaged about 9% below the normal hearing subjects. Although there was a weak to moderate correlation between the hearing impaired subjects' scores on the discrimination test and their scores on the HHIA, it was not statistically significant. It was concluded that, with further research, the CID Everyday sentences, with competing cafeteria noise, have potential merit as a speech discrimination procedure to quantify the hearing handicap produced by a high frequency hearing loss.

Abstract (sommario):

INTRODUCTION: Confidence in the reliability and validity of a diagnosis of APD is currently low among clinical and professional groups, principally due to the lack of a gold standard test sensitive to APD, differences in accepted diagnostic criteria and considerable variability in clinical test batteries implemented. Listening difficulties associated with APD are also not exclusive to the disorder, and are frequently observed in individuals with alternative disorders such as specific language impairment, specific reading impairment, and attention deficit disorder. The research undertaken in this thesis attempts to identify subjective and objective measures that differentiate adults diagnosed with clinical-APD from oto-neurologically normal adults with no perceived hearing difficulties using a popular hearing inventory, three speech in-noise tests and the speech-evoked auditory brainstem response test. The Speech, Spatial and Qualities of Hearing Scale (SSQ), presents a rich array of communication environments that reflect the three-dimensional dynamic auditory world humans live in. It comprises three hearing subscales - speech intelligibility, spatial awareness and other qualities of hearing. The three speech-in-noise tests - Who Is Right, the Children’s Coordinate Response Measure with competing male-talker (CCRM1) and the Children’s Coordinate Response Measure with competing speech-shaped noise (CCRM2) assess different aspects of auditory cognition, (i.e., low level auditory processing and auditory attention). In all three speech tests the target signal and competing noise were presented simultaneously and dichotically via headphones, and an automatic adaptive approach was used to adjust the signal-to-noise ratio. The speech-ABR was elicited under monaural and binaural stimulation, with a 40ms /da/ consonantvowel syllable. Several measures can be used to characterise the speech-ABR onset response and frequency following response (FFR) including response timings, responses amplitudes, and stimulus versus response waveform correlation coefficients. METHODOLOGY: Normative data were derived for all three subscales of the SSQ Hearing Scale, for the three behavioural speech tests, and the speech-ABR, following the collection and analysis of data obtained from 52 adults with normal hearing and no reported listening difficulties. Research data for the same outcome measures were obtained from a clinical-APD group (n=21) and two smaller APD subgroups (a developmental-APD group comprising 10 subjects and an acquired- APD group consisting of 8 subjects). SUMMARY OF RESEARCH FINDINGS: SSQ self-reported hearing ability scores were significantly worse for the clinical-APD group (n=21) compared with the normal hearing control group (n=52) for the ‘speech intelligibility’ and ‘other qualities of hearing’ subscales at the 0.01 alpha level. Statistically significant group differences were also observed for CCRM1 and Who Is Right tasks - poorer scores were apparent for the clinical-APD group for both tests, providing some evidence for deficits in auditory attention and auditory processing in these subjects. No statistically significant group differences were observed for all speech-ABR response timings or key features of the FFR. Independent Sample T-tests did suggest that statistically significant group differences were apparent for V-A amplitude, V-A slope and V-A area; however these differences may be attributed to age and gender distribution differences between the two groups. 75% of the acquired-APD subjects failed the CCRM1 task (a test of auditory attention), compared with 30% of the developmental-APD group. 50% of the acquired-APD subjects failed the Who Is Right task (a test of auditory processing) compared with 10% of the developmental- APD group; and 50% of the acquired -APD group failed the CCRM2 task (a test of attentional allocation and/or auditory processing) compared with 10% of the developmental-APD group. Findings for the speech-ABR also revealed evidence for low level central auditory nervous system anomalies for both APD subgroups. Abnormalities in the speech-ABR FFR were observed in 30% of developmental-APD subjects compared with 62.5% of acquired-APD subjects; whilst mild anomalies were present in 20% of developmental-APD subjects compared with 37.5% of acquired-APD subjects for the onset response. Altogether these results provide evidence for the deficits in auditory cognition for both APD-groups. Although this test battery demonstrates low sensitivity overall for the developmental-APD group, it does show better sensitivity for the acquired-APD subjects who exhibit more severe deficits in auditory cognition.

Abstract (sommario):

AbstractMyofascial Pain Dysfunction Syndrome or myofascial pain disorder is one among the triad of disturbances that is encompassed within the umbrella term, TMJ disorders. Due to a lack of consensus on definitive symptoms and mode of diagnosis, it continues to remain an elusive entity for clinicians working with head and neck disorders and dentists alike. Additionally, There is a general lack of simplification in literature to enhance understanding and this is further complicated by the use of multiple descriptive terminologies to refer to the disorder. It is the objective of this chapter to provide a comprehensive overview of the subject for the reader, to clarify the various nuances of diagnosis, treatment planning and management modalities in addition to throwing light on the evolving terminologies, causative mechanisms and recent trends in MPDS management. The author has also highlighted the importance of a multi modality management approach, psychological rehabilitation with long term patient follow up. The authors personal experience with the use of specialised splints has been elucidated with relevant clinical case scenarios.

Abstract (sommario):

Visual and hearing impairments, congenital or acquired, are much more common in people with intellectual disability (ID) than the general population. These can be missed or diagnosed with delay if professionals rely just on the subjective reports by the families/care givers rather than objective screening and assessment. People with ID might be unable to complain about a visual or hearing impairment due to their communication difficulties. Therefore, diagnostic overshadowing might occur whereby these conditions might present with atypical signs and symptoms (e.g. loss of skills, isolation, and challenging behaviours) which could be attributed to dementia, depression, or other mental health problems. There has also been an overrepresentation of autistic-like features and autism spectrum disorder reported in people with visual and hearing impairment. Raising awareness of these comorbidities in people with ID will therefore facilitate early diagnosis and implementation of appropriate management strategies that can improve service provision for this vulnerable population.

Abstract (sommario):

Pediatric hearing aid fitting has always been a challenge for an audiologist. There are lots of technological advances in the field of hearing aids which are yet to be verified and used in the pediatric population. The chapter focuses on reviewing the recent advancements in hearing aid technology which can benefit children with hearing impairment. It is attempted to determine the application of these technology in pediatric hearing aid fitting. The lack of translational research to provide empirical evidence in this area is highlighted. It is stressed in the chapter that audiologists should use their clinical knowledge and use appropriate verification methods to make appropriate recommendations in pediatric hearing aid fitting.

Abstract (sommario):

Most rheumatological diagnoses are made through effective history taking and physical examination rather than investigation. Systemic symptoms, such as weight loss, anorexia, and fever, point to systemic diseases such as rheumatoid arthritis, other polyarthritides, systemic lupus erythematosus, polymyalgia, and vasculitides. Swelling of joints is a symptom commonly reported by patients with no objective evidence of this on examination. Inflammatory arthropathies should not be diagnosed unless the physician is able to identify objective swelling, if necessary by arranging a prompt review during an active episode. Diagnostic criteria for the systemic rheumatic diseases are useful in directing the history taking to verify a suspected diagnosis. Investigations are best used to confirm a strongly suspected diagnosis, already made on the basis of history and examination, not as a screening tool for rheumatic disease.

Abstract (sommario):

Hearing disorders are quite common in our days, not only due to congenital causes, environmental factors abut also due to the increased rate of diagnosis. Hearing loss is one of the commonest reasons to visit an ENT Department both in the clinic and in the acute setting. Approximately 15% of American adults (37.5 million) aged 18 and over report some trouble hearing. One in eight people in the United States (13 percent, or 30 million) aged 12 years or older has hearing loss in both ears, based on standard hearing examinations. About 2 percent of adults aged 45 to 54 have disabling hearing loss. The rate increases to 8.5 percent for adults aged 55 to 64. Nearly 25 percent of those aged 65 to 74 and 50 percent of those who are 75 and older have disabling hearing loss. These figures depict the impact on patients' quality of life and the necessity for early and accurate diagnosis and treatment. It is important to mention that congenital hearing loss and deafness is also a condition that requires early diagnosis and hearing aiding in order to develop normal speech. Profound, early-onset deafness is present in 4–11 per 10,000 children, and is attributable to genetic causes in at least 50% of cases.

Abstract (sommario):

Abstract The pre-adolescent age is basic in the beginning of the development of body kinematics. During this age the body structure needs to continuously search for stabilization due to the modification in body segment lengths. This behavior can evolve into incorrect postural attitudes that, if not properly treated, can lead to behaviors that are difficult to recover with advancing age. These incorrect attitudes require an accurate and early diagnosis that can be put in place by expert doctors and clinicians. As well known, sporting activity in this age can help the development of proprioceptive apparatus and the musculoskeletal one. Volleyball is considered a complete sport thanks to the wide range of actions necessary for a match. Following this evaluation, it was decided to carry out a monitoring study of young volleyball players in what is one of the capitals of Italian volleyball, i.e. Modena. To achieve this objective, in this work, 97 female volleyball players have been analyzed during their adolescent and pre-adolescent age. The study has the objective to collect data and design an exercise routine for the training to prevent postural problems. Finally, the data have been analyzed and the most representative ones have been reported in this paper.

Abstract (sommario):

The paper concentrate on problems connected with problems of peoples with disability. The main aims of the paper is to measure the level of quality of service in the case of architectural barriers in municipal offices by peoples in disability. We made following hypothesis: the types of disability significantly affects the perception of quality of services in municipal office regarding architectural barrier. The problem of satisfaction of people with disability in the case of architectural barriers in municipal office in Sosnowiec was analyzed from type of disability point of view. We distinguished five main types of disability in the paper: sensory impairment – a lack, damage or disorder of sensory analysers’ function (this category includes the blind, the visually impaired, the deaf, hard of hearing persons and people with visual and auditory perception disorders); intellectual impairment – mental retardation; social functioning impairment – disorders of neural and emotional balance; communication impairment – hindered verbal contact (speech impediments, autism, stammering); motor impairment – people with motor organ dysfunction. On the basis of that are discussed in this publication the research, we can conclude that the overall assessment of architectural barriers for people with disabilities is as in the case of the Municipal Office in Sosnowiec at an average level. The problems focus mainly on matters of specialized service selected groups of customers with disabilities who require further elaboration. Another type of problem is to issue a limited number of parking spaces for the disabled, but for objective reasons, it will be difficult to solve. Also we can say that the assessment of the architectural barriers by peoples with various types of disability vary significantly. The architectural barriers are the problem especially for people with motor disabilities – those persons are going to municipal office often and because of type of their disability barriers within the office and near the office is the big problem for them. The results are supporting the hypothesis that the type of disability affects perception of architectural barriers by peoples with disabilities.
