Hearing loss (HL) is a common sensory disorder in humans with high genetic heterogeneity. To date, over 145 loci have been identified to cause nonsyndromic deafness. Furthermore, there are countless families unsuitable for the conventional linkage analysis. In the present study, we used a custom capture panel (MiamiOtoGenes) to target sequence 180 deafness-associated genes in 5 GJB2 negative de...
Previous studies have documented that speakers of French, a language with predictable stress, have difficulty distinguishing nonsense words that vary in stress position solely (stress ‘‘deafness’’). In a sequence recall task with adult speakers of five languages with predictable stress (Standard French, Southeastern French, Finnish, Hungarian and Polish) and one language with non-predictable st...
This paper demonstrates that accounting for the moral harm of selecting for deafness is not as simple or obvious as the widespread negative response from the hearing community would suggest. The central questions addressed by the paper are whether our moral disquiet with regard to selecting for deafness can be adequately defended, and if so, what this might entail. The paper considers several d...
BACKGROUND Cochleovestibular symptoms, such as vertigo, tinnitus, and sudden deafness, are common manifestations of microvascular diseases. However, it is unclear whether these symptoms occurred preceding the diagnosis of peripheral artery occlusive disease (PAOD). Therefore, the aim of this case-control study was to investigate the risk of PAOD among patients with vertigo, tinnitus, and sudden...
Deafness affects ∼2 in 1000 children and is one of the most common congenital impairments. Permanent hearing loss can be treated by fitting hearing aids. More severe to profound deafness is an indication for cochlear implantation. Although newborn hearing screening programs have increased the identification of asymmetric hearing loss, parents and caregivers of children with single-sided deafnes...
Congenital hearing loss has been documented to occur in 1 of 1000 live births, with over half of these cases predicted to be hereditary in nature. 2 Most hereditary hearing loss is inherited in a recessive manner, accounting for approximately 85% of non-syndromic hearing loss (NSHL). Deafness is an extremely genetically heterogeneous disorder, shown by the fact that 33 loci for recessive NSHL a...
This paper addresses deafness problem that occur when MAC protocols are designed by using directional antennas. Briefly, Deafness is caused when two nodes are busy in ongoing transmission and another node (Deaf Node) wants to communicate with any of these busy nodes. But it gets no response because transmission of two nodes is in process. This paper proposes DMAC/DS (Directional MAC with Deafne...
Hearing loss due to mutations in the connexin gene family, which encodes gap junctional proteins, is a common form of hereditary deafness. In particular, connexin 26 (Cx26, GJB2) mutations are responsible for ~50% of non-syndromic hearing loss, which is the highest incidence of genetic disease. In the clinic, Cx26 mutations cause various auditory phenotypes ranging from profound congenital deaf...
It has long been recognized that heredity plays a major role in hearing impairment. Although the facts about the genetic basis of hearing loss have fascinated both clinicians and geneticists for a long time, it is only within the last few years that the genes and molecular mechanisms underlying deafness have begun to be discovered. There is a great deal of genetic heterogeneity in deafness. Thi...
Background: Long QT syndromes (LQT) are genetic abnormalities of ventricular repo-larization, with an estimated incidence of about one per 10000 births. It is characterized by prolongation of the QT interval in electrocardiogram (EKG) and associated with a high risk for syncope and sudden death in patients. Type of this syndrome is association with congenital deafness. Our objective was to eval...
