Methods: ASSR thresholds were measured at octave intervals from 500 Hz to 4000 Hz. They were recorded in 389 ears with normal hearing and middle ear function, and in a further 189 ears with temporary middle ear dysfunction. The modal corrected age at which the tests were undertaken was four weeks, with a minimum of one week and maximum corrected age of 26 weeks. Results: The mean ASSR thresholds of those with normal hearing were 47dB HL at 500 Hz, 36dB HL at 1000 Hz, and 34dB HL at both 2000 Hz and 4000 Hz. Standard deviations (SDs) from the mean ranged from 7.7 to 9.9dB. For those with middle ear dysfunction the mean ASSR thresholds were significantly greater at each frequency, with thresholds of 65dB HL at 500 Hz, 55dB HL at 1000 Hz, 53dB HL at 2000 Hz and 52dB HL at 4000 Hz. SDs from the mean ranged from 12.9 to 17.9dB. Mean thresholds decreased at all frequencies during the first half of infancy. In those with normal middle ear function the decrease was only 2dB at 500 Hz, but was over 5dB at both 1000 and 2000 Hz and was 4dB at 4000 Hz. A similar decrease was seen over the same period in those with middle ear dysfunction. Conclusions: ASSR thresholds measured in early infancy are affected by both test age and the presence of middle ear dysfunction and are more variable than ABR thresholds measured in babies with normal hearing or a mild conductive loss. A flexible test battery for gaining frequency specific information is therefore required at this age.","PeriodicalId":88223,"journal":{"name":"Audiological medicine","volume":"72 1","pages":"26 - 32"},"PeriodicalIF":0.0,"publicationDate":"2011-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86373320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Congenital hearing loss is the hereditary sensorial defect most commonly observed in newborns; it affects 1.12 per 1000 children. If we also consider acquired forms and late-onset forms of hearing loss, prevalence grows to 1.33 per 1000 children. In Italy the overall prevalence is 0.78 per 1000 for males and 0.69 per 1000 for females (1). Fifty percent of sensorineural deafness is due to genetic causes, most of which are inherited in an autosomal recessive manner. Genetic deafness is very heterogeneous and can occur in non-syndromic form (70% of cases) or in syndromic form (30% of cases). Several syndromes are associated with deafness, heart anomalies and other diseases: Charge syndrome, Leopard syndrome, Fabry syndrome, Refsum syndrome, SALL4 syndrome and Mobius syndrome. Until recently only one syndrome in which deafness and heart problems are the sole features has been described – Jervell and Lange-Nielsen syndrome (J-LNS). This condition, if not timely discovered and treated, may culminate in sudden death. However, in December 2010, Nature Neuroscience published an article about a new channelopathy termed SANDD syndrome, characterized by sinoatrial node dysfunction and deafness (2). These recent data underline the importance of a cardiac investigation in cases of suspected genetic deafness of unknown cause. It is probable that in the future other syndromes involving both the heart and the hearing system will be found. We have to consider that many of the causative genes of deafness have not yet been identifi ed. Furthermore, genes involved in hearing impairment encode proteins of different classes, such as cell adhesion and cytoskeleton proteins, transcription factors, extracellular matrix components, membrane","PeriodicalId":88223,"journal":{"name":"Audiological medicine","volume":"35 1","pages":"1 - 3"},"PeriodicalIF":0.0,"publicationDate":"2011-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87972994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pre-lingual non-syndromic hearing loss is present in 1 in 700 children and in half of the cases the hearing impairment is caused by genetic factors. Methods: We analysed an Italian family with a bilateral sensorineural HL present in several family members and inherited in an autosomal dominant manner. To perform a linkage study, subjects were genotyped with high density SNP arrays. Parametric linkage analysis using Merlin detected a significant 40-Mb locus on chromosome 14. Since the COCH gene, already known to be involved in causing HL, was located within this interval, a mutational search was carried out. Result: A novel mutation (p.A487P) affecting a highly conserved residue located within the vWFA2 domain was detected and segregates with the disease. Conclusion: This is the first Italian case of HL due to mutations within the COCH gene and it is also the first one showing some individuals affected by vestibular dysfunction due to the direct involvement of the vWFA2 domain.","PeriodicalId":88223,"journal":{"name":"Audiological medicine","volume":"22 4","pages":"4 - 7"},"PeriodicalIF":0.0,"publicationDate":"2011-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72634954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the reliability and validity of Audioscan and Békésy audiometry. Method: Audioscan and Bekesy audiometry were undertaken at a comparable sweep rate in 21 subjects with normal hearing. Each subject underwent conventional pure tone audiometry, Audioscan and Békésy audiometry. Test sessions were conducted on four consecutive days. Results: The results indicate that more than 90% of participants had variability of hearing threshold of less than 10dB at all frequencies. Median variances for thresholds obtained from Audioscan were less than 10dB2 for all frequencies except 4.0 kHz. In contrast, thresholds obtained from Békésy showed greater variance, more than 15dB2 at all frequencies when it was undertaken at the same sweep rate. Audioscan results were in excellent agreement with the PTA at all frequencies except at 0.25, 6 and 8 kHz, whereas Békésy results differed significantly from PTA at all frequencies except at 6 kHz. Conclusion: Data from the present study indicate that the Audioscan can provide reliable and valid hearing thresholds. However, a slow sweep rate appears to be more desirable for Békésy audiometry to improve its reliability and validity in detecting hearing sensitivity.","PeriodicalId":88223,"journal":{"name":"Audiological medicine","volume":"260 1","pages":"40 - 46"},"PeriodicalIF":0.0,"publicationDate":"2011-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89135122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this paper is to study how a group of experts performs a task of severity judgment compared with a task of intelligibility judgment. Study design: During an off-line experiment, 33 stimuli were presented as icons on a Powerpoint slide. Each icon was associated with a line allowing scoring of each stimulus heard by a simple click on it; each stimulus was judged in terms of voice, resonance, prosody and phonemic qualities. With an analogical scale placed at the bottom of the screen, the judges were asked to put a copy of the icon along the line; the space above the line was used for severity and the one under the line for the deterioration of intelligibility, the arrow being oriented on the right side for the ‘most severe’ or ‘the least intelligible’ and representing a range from 1 to 30. Results: The mean scores of severity and deterioration of intelligibility were 9.8 (+/− 1.72) and 8.2 (+/− 1.59), respectively. Three judges differed in the distribution of the scores, whereas two others gave a similar score distribution. Where a difference exists, the trend is, in the mid-range of severity, to give a lower score for the deterioration of intelligibility. This is associated with a difference as to how the judges use the characteristics of speech analysed just before performing the judgment. Conclusion: There is an argument for measuring intelligibility at the surface code level with a word recognition test or ordinal scales and for allowing the use of interval scales for severity judgment.","PeriodicalId":88223,"journal":{"name":"Audiological medicine","volume":"12 1","pages":"171 - 178"},"PeriodicalIF":0.0,"publicationDate":"2010-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74761733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the impairment of hearing discrimination, attention, memory and perception, dyslexia causes the inability to process and interpret linguistic and verbal information effectively. Standard audiological examination is much less useful than low redundancy speech tests and electro-physiological examination, which are the only objective measures of central auditory processing. The aim of the study was to assess the usefulness of low redundancy speech tests and dichotic tests in the diagnosis of developmental dyslexia in children. Methods: Ten children aged 7–15 years were tested by a dichotic numeral test, a dichotic verbal minimal-pair test, and a Calearo test. Results: The experiments demonstrated that the dyslectic group achieved worse results in the above tests compared to the control group. This suggests information exchange disorders between the hemispheres, a lack of synchronization of acoustic perception in dichotic tests, and damage of the structures responsible for central auditory processing in the dominating hemisphere. Conclusions: The results of our study confirm the existence of information exchange disorders between the hemispheres and the lack of synchronization of acoustic perception in dichotic tests, where the signal is presented to both ears simultaneously. Much worse results in low redundancy tests reveal, moreover, damage of the structures responsible for central auditory processing in the dominating hemisphere. Altogether, this research has proved the usefulness of the conducted tests in the diagnostics of central auditory processing disorders in patients with dyslexia.","PeriodicalId":88223,"journal":{"name":"Audiological medicine","volume":"1 1","pages":"191 - 195"},"PeriodicalIF":0.0,"publicationDate":"2010-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83097216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
