Association between sleep-disordered breathing and hearing disorders: Clinical observation in Sicilian patients
2015
Introduction: To examine the putative association between Sleep-Disordered breathing and hearing disorders Material and methods: 120 Sicilian subjects ranging from 14 to 85 years of age who were divided in 46 cases suffering from tinnitus (G1 group) and 74 controls (G2 group) were evaluated through STOP BANG screening questionnaire and Four-Variable Screening Tool; after Data collecting each subject underwent Audiological assessment by multi-frequency audiometry (PTA) and Transient-evoked otoacoustic emissions (TEOAE-diagnostic) for each ear. Results: Cases showed: PTA significantly severe than the control group (58.70% vs. 16.89% hearing loss; P<0.001), such as a lower signal-to-noise r…
Genetic determinants of ototoxicity during and after childhood cancer treatment: Protocol for the pancarelife study
2019
BACKGROUND: Survival rates after childhood cancer now reach nearly 80% in developed countries. However, treatments that lead to survival and cure can cause serious adverse effects with lifelong negative impacts on survivor quality of life. Hearing impairment is a common adverse effect in children treated with cisplatin-based chemotherapy or cranial radiotherapy. Ototoxicity can extend from high-tone hearing impairment to involvement of speech frequencies. Hearing impairment can impede speech and language and neurocognitive development. Although treatment-related risk factors for hearing loss following childhood cancer treatment have been identified, the individual variability in toxicity of…
Association of candidate pharmacogenetic markers with platinum-induced ototoxicity
2020
Genetic association studies suggest a genetic predisposition for cisplatin-induced ototoxicity. Among other candidate genes, thiopurine methyltransferase (TPMT) is considered a critical gene for susceptibility to cisplatin-induced hearing loss in a pharmacogenetic guideline. The PanCareLIFE cross-sectional cohort study evaluated the genetic associations in a large pan-European population and assessed the diagnostic accuracy of the genetic markers. 1,112 pediatric cancer survivors who had provided biomaterial for genotyping were screened for participation in the pharmacogenetic association study. 900 participants qualified for inclusion. Based on the assessment of original audiograms, patien…
How not to give up on train travel when you are deaf ?
2015
TRANSED 2015 - 14th International Conference on Mobility and Transport for Elderly and Disabled Persons, LISBONNE, PORTUGAL, 28-/07/2015 - 31/07/2015; The SUrDyn project aims at the design of an innovative visual information system, dedicated to travelers who cannot hear or understand audio disrupted announcements (e.g. cancellation, delay...) when they are in train stations. It is based on two previously developed systems: the Jade signer avatar, which informs travelers in French Signs Language, and an animated graphics translation. The objective is to combine these two approaches, in an optimal manner. We proposed a comprehension task to 159 participants divided in three groups: 53 deaf p…
Endothelial nitric oxide synthase upregulation in the guinea pig organ of Corti after acute noise trauma.
2004
Endothelial nitric oxide synthase (eNOS) upregulation was identified 60 h after acute noise trauma in morphologically intact cells of the reticular lamina in the organ of Corti of the guinea pig in the second turn of the cochlea. Using gold-coupled anti-eNOS antibodies and electron microscopy, it was shown that eNOS expression was upregulated in all cell areas and cell types except inner hair cells. Furthermore, eNOS was found in the organelle-free cytoplasm and in mitochondria of various cell types. The density of eNOS in mitochondria was considerably higher compared with the surrounding cytoplasm. Since eNOS activity is regulated by calcium, the eNOS detection was combined with calcium pr…
Young woman with Branchio-Oto-Renal Syndrome and a novel mutation in the EYA-1 gene
2011
Branchio-oto-renal (BOR) syndrome is an autosomal dominant disease clinically characterized by the coexistence of some or all of the following major disorders: deafness, cervical branchial fistulae, preauricular pits, and renal abnormalities. Most families with BOR syndrome have mutations on the EYA-1 gene on chromosome 8q. We present the case of a 23-year-old Italian woman without a familial history of BOR syndrome. The patient, who had hearing loss and a history of surgeries for correction of bilateral cervical branchial fistulae and bilateral preauricular pits, presented with renal impairment, hypertension and overt proteinuria. DNA sequencing showed a novel heterozygous mutation 1420-14…
SAT0513 Brainstem Auditory Evoked Potentials and Visual Potentials in Kawasaki Disease: Expression of CNS Vasculitis?
2015
Background Kawasaki disease (KD) is an acute, self-limited vasculitis of infants and children that is nowadays the most common cause of acquired heart disease in children. Transient sensorineural hearing loss (20 to 35 dB) is a possible complication of acute phase KD and may be related to salicylate toxicity in some patients. Objectives Brainstem Auditory Evoked Potentials (BAEPs) , and Visual Evoked Potentials (VEPs) were examined in 43 children (age: 0,8-7,5 years) affected by KD. No risk factors for hearing loss and/or neurological impairment of CNS were identified in all the patients. BAEPs showed altered waves II to V, in 18 patients (42%). Among these, in 4 patients (20%) VEPs showed …
Haploinsufficiency of 16.4 Mb from chromosome 22pter-q11.21 in a girl with unilateral conductive hearing loss.
2009
We present the postnatal diagnosis of a de novo der(18)t(18;22)(p11.32;q11.21)pat, resulting in an unbalanced 45,XX,der (18)t(18;22) karyotype in a girl with conductive hearing loss on the left and ptosis of the right upper eye-lid. Unilateral ptosis was also observed in the patient’s 2 years and 8 months younger sister, who grows noticeably faster and appears to be a much quicker learner. After speech therapy the patient was eventually placed in normal school. The haploinsufficient 16.4-Mb region on chromosome 22pter→q11.21 contains 10 genes as well as many predicted genes, pseudogenes, and retrotransposed sequences with unknown functions. This observation may prove useful for prenatal dia…
Prevalence of Hearing Impairment Among High-Risk Newborns in Ibadan, Nigeria
2018
The burden of severe hearing impairment is increasing with two-thirds of these hearing impaired people residing in developing countries. Newborn hearing screening helps to identify early, babies who need intervention in order to prevent future disability. Neither universal nor targeted hearing screening programme is available in Nigeria. Objectives: This study was carried out to assess the prevalence of hearing impairment among high-risk newborns in UCH and the associated risk factors. Materials and Methods: Two hundred one newborns in the neonatal unit of UCH with risk factors for hearing impairment had hearing screening done using automated auditory brainstem response (AABR) at 30, 45, an…
Essential of audiology: screening and postscreening
2014
Newborn hearing screening is a type of screening testfor the early detection of hearing loss. It can recognizewith good accuracy newborns affected by hearingimpairment allowing an early diagnosis and interventionand avoiding cognitive and linguistic deficits [1-6].The incidence of bilateral sensorineural hearing loss(SNHL) in Sicily is 2.35 cases per 1000 newborns; thisvalue increases to 2.95 if we consider also unilateral SNHL[2,3] and to 10 cases per 1000 births among infants at risk[7-9].A correct newborn hearing screening programme isbased on different protocols depending on the presence/absence of audiologic risk factors:† Newborns without risk factors: [1-3]Initial Hearing Screening (…
