Initial experience with the Sophono Alpha 1 osseointegrated implant.
2013
In the last several years, bone anchored hearing aids have proven to be useful in treating conductive and mixed unilateral or bilateral hearing loss, as well as for sensorineural unilateral hearing loss. The Sophono Alpha 1 model has the advantage of not requiring an abutment, with it being coupled by magnetism instead. We report the cases of 3 infants with congenital malformations of external and middle ear. Audiometry showed conductive hearing loss. All 3 patients were implanted with Alpha 1 model (Sophono). Patients evolved satisfactorily. After 30 days we applied the processor and the control audiometry showed a marked improvement of hearing thresholds, although without a complete closu…

Gentamicin increases nitric oxide production and induces hearing loss in guinea pigs.
2008
Objectives/Hypothesis: Gentamicin application is an important therapeutic option for Meniere's disease. However, even if given at intervals, a destruction of the cochlea was often observed in various animal models together with an increased content of nitric oxide (NO) and reactive oxygen species. The present study was undertaken to identify the correlation between hearing threshold alteration and the NO production in the lateral wall and organ of Corti of the guinea pig in response to gentamicin application. Study Design: Prospective animal study in guinea pigs. Methods: A single dose of gentamicin (10 mg/kg body weight) was injected intratympanally into male guinea pigs and the auditory b…
Psychological and physical well-being in hearing-impaired children
2007
Summary Objectives The purpose of this study was to evaluate the psychological and physical well-being in 6–11-year-old hearing-impaired children. Methods The cohort consisted of 70 boys and 61 girls who either attended a special school for deaf children ( n = 78) or a mainstream school ( n = 53). We used the FKSI (Frankfurt Self-Concept Scales for Children). Results Children in special schools saw themselves in a less favourable light than children in mainstream schools. They were less confident and less assertive. They reached lower scores in making friends, and were more anxious and sad. Children attending mainstream schools were found to be more self-confident the more pronounced the …
Manifestation of speech and language disorders in children with hearing impairment compared with children with specific language disorders.
2010
Children with hearing impairment (HI) often suffer from speech and language disorders. We wondered if the manifestation of these disorders resembled the ones in children with specific language impairment (SLI). Using matched pairs, we compared the manifestation of a speech and language disorder in 5- and 6-year-old children with HI and SLI. We looked at receptive language skills using the Reynell scales, the lexicon, syntax and morphology, output phonology, and phonological short-term memory. Receptive language skills were more impaired in HI children. No significant differences were recorded for all other domains. We conclude that language deficits that are at least partially caused by the…
Auditory Neuropathy in Children
2001
Auditory neuropathy is a sensorineural disorder characterized by absent or abnormal auditory brainstem evoked potentials and normal cochlear outer hair cell function. A variety of processes is thought to be involved in its pathophysiology and their influence on hearing may be different. We present here the diagnostic sequence and management of two new cases of auditory neuropathy in breastfeeding children.
An experimental comparative study of dexamethasone, melatonin and tacrolimus in noise-induced hearing loss.
2008
The calcineurin inhibitor tacrolimus (TCR) and the pineal gland hormone and antioxidant melatonin (MLT) have been shown to possess otoprotective properties against noise-induced hearing loss (NIHL). In contrast, dexamethasone (DXM) was not effective as an otoprotective agent against NIHL. Further studies are needed to understand the exact molecular mechanisms involved.Exposure to noise pollution and use of audio devices for long periods of time at high volume is known to cause hearing loss or NIHL. Our goal was to evaluate the effectiveness of various known compounds such as the anti-inflammatory DXM, the antioxidant MLT and the immunosuppressant TCR against NIHL.Thirty-two Wistar rats were…
First Experiences With the Ponto⢢ SuperPower Osseointegrated Device
2018
Osseointegrated hearing devices Power and SuperPower present indications for bone thresholds of 55 and 65 dB respectively. We conducted a prospective observational study of a series of six cases with mixed hearing loss for whom implantation of the DAO Ponto™ Super-Power was performed. Tonal and verbal evaluations without and with background noise (HINTS) were performed prior to implantation and six months after adaptation. All the participants showed improvement in tonal and verbal results, varying according to the degree of contralateral hearing loss. The verbal results with background noise were noteworthy, where most of the patients obtained a signal-to-noise ratio between 2 and 4 dB. Th…
Prelingual sensorineural hearing loss and infants at risk: Western Sicily report.
2013
Objective: To evaluate independent etiologic factor associated with sensorineural hearing loss (SNHL) in newborn at risk; to study the role of their interaction especially in NICU infants who present often multiple risk factors for SNHL. Methods: The main risk factors for SNHL reported by JCIH 2007 were evaluated on 508 infant at risk ranging from 4 to 20 weeks of life, transferred to the Audiology Department of Palermo from the main births centers of Western Sicily. After a global audiological assessment, performed with TEOAE, tympanometry and ABR, the prevalence and the effect of risk factors was statistically studied through univariate and multivariate analysis on the total population (n…
The Jervell and Lange-Nielsen syndrome.
1991
Deafness and electrocardiographic changes (prolongation of the Q-T interval and inversion of the T wave) with a clinical picture of syncopal attacks and sudden death, were described as a distinct syndrome by Jervell and Lange-Nielsen in 1957. The syndrome is inherited as an autosomal recessive trait. In this study, all the cases reported since 1957 and their proposed prevalence are reviewed. The authors describe the 4 cases they have studied, all of which presented congenital sensorineural hearing loss and electrocardiographic changes characteristic of the syndrome. The relatively high number of cases they have encountered casts doubt on literature that states that the syndrome occurs more …
