Hearing Loss, Sensorineural
The essential part of the hearing organ consists of two labyrinthine compartments: the bony labyrinthine and the membranous labyrinth. The bony labyrinth is a complex of three interconnecting cavities or spaces (COCHLEA; VESTIBULAR LABYRINTH; and SEMICIRCULAR CANALS) in the TEMPORAL BONE. Within the bony labyrinth lies the membranous labyrinth which is a complex of sacs and tubules (COCHLEAR DUCT; SACCULE AND UTRICLE; and SEMICIRCULAR DUCTS) forming a continuous space enclosed by EPITHELIUM and connective tissue. These spaces are filled with LABYRINTHINE FLUIDS of various compositions.

Hair Cells, Auditory
Sensory cells in the organ of Corti, characterized by their apical stereocilia (hair-like projections). The inner and outer hair cells, as defined by their proximity to the core of spongy bone (the modiolus), change morphologically along the COCHLEA. Towards the cochlear apex, the length of hair cell bodies and their apical STEREOCILIA increase, allowing differential responses to various frequencies of sound.
A layer of stratified EPITHELIUM forming the endolymphatic border of the cochlear duct at the lateral wall of the cochlea. Stria vascularis contains primarily three cell types (marginal, intermediate, and basal), and capillaries. The marginal cells directly facing the ENDOLYMPH are important in producing ion gradients and endochoclear potential.
Electronic hearing devices typically used for patients with normal outer and middle ear function, but defective inner ear function. In the COCHLEA, the hair cells (HAIR CELLS, VESTIBULAR) may be absent or damaged but there are residual nerve fibers. The device electrically stimulates the COCHLEAR NERVE to create sound sensation.
The testing of the acuity of the sense of hearing to determine the thresholds of the lowest intensity levels at which an individual can hear a set of tones. The frequencies between 125 and 8000 Hz are used to test air conduction thresholds and the frequencies between 250 and 4000 Hz are used to test bone conduction thresholds.
Autosomal recessive hereditary disorders characterized by congenital SENSORINEURAL HEARING LOSS and RETINITIS PIGMENTOSA. Genetically and symptomatically heterogeneous, clinical classes include type I, type II, and type III. Their severity, age of onset of retinitis pigmentosa and the degree of vestibular dysfunction are variable.
Hearing Loss, Central
Hearing loss due to disease of the AUDITORY PATHWAYS (in the CENTRAL NERVOUS SYSTEM) which originate in the COCHLEAR NUCLEI of the PONS and then ascend bilaterally to the MIDBRAIN, the THALAMUS, and then the AUDITORY CORTEX in the TEMPORAL LOBE. Bilateral lesions of the auditory pathways are usually required to cause central hearing loss. Cortical deafness refers to loss of hearing due to bilateral auditory cortex lesions. Unilateral BRAIN STEM lesions involving the cochlear nuclei may result in unilateral hearing loss.
A hereditary condition characterized by multiple symptoms including those of DIABETES INSIPIDUS; DIABETES MELLITUS; OPTIC ATROPHY; and DEAFNESS. This syndrome is also known as DIDMOAD (first letter of each word) and is usually associated with VASOPRESSIN deficiency. It is caused by mutations in gene WFS1 encoding wolframin, a 100-kDa transmembrane protein.
Rare, autosomal dominant disease with variable penetrance and several known clinical types. Characteristics may include depigmentation of the hair and skin, congenital deafness, heterochromia iridis, medial eyebrow hyperplasia, hypertrophy of the nasal root, and especially dystopia canthorum. The underlying cause may be defective development of the neural crest (neurocristopathy). Waardenburg's syndrome may be closely related to piebaldism. Klein-Waardenburg Syndrome refers to a disorder that also includes upper limb abnormalities.
A condition caused by a deficiency of PARATHYROID HORMONE (or PTH). It is characterized by HYPOCALCEMIA and hyperphosphatemia. Hypocalcemia leads to TETANY. The acquired form is due to removal or injuries to the PARATHYROID GLANDS. The congenital form is due to mutations of genes, such as TBX1; (see DIGEORGE SYNDROME); CASR encoding CALCIUM-SENSING RECEPTOR; or PTH encoding parathyroid hormone.

Hearing Loss, Conductive
Either of a pair of compound bones forming the lateral (left and right) surfaces and base of the skull which contains the organs of hearing. It is a large bone formed by the fusion of parts: the squamous (the flattened anterior-superior part), the tympanic (the curved anterior-inferior part), the mastoid (the irregular posterior portion), and the petrous (the part at the base of the skull).
A spiral tube that is firmly suspended in the bony shell-shaped part of the cochlea. This ENDOLYMPH-filled cochlear duct begins at the vestibule and makes 2.5 turns around a core of spongy bone (the modiolus) thus dividing the PERILYMPH-filled spiral canal into two channels, the SCALA VESTIBULI and the SCALA TYMPANI.
Impairment of the ability to perform smoothly coordinated voluntary movements. This condition may affect the limbs, trunk, eyes, pharynx, larynx, and other structures. Ataxia may result from impaired sensory or motor function. Sensory ataxia may result from posterior column injury or PERIPHERAL NERVE DISEASES. Motor ataxia may be associated with CEREBELLAR DISEASES; CEREBRAL CORTEX diseases; THALAMIC DISEASES; BASAL GANGLIA DISEASES; injury to the RED NUCLEUS; and other conditions.
Enlargement of the THYROID GLAND that may increase from about 20 grams to hundreds of grams in human adults. Goiter is observed in individuals with normal thyroid function (euthyroidism), thyroid deficiency (HYPOTHYROIDISM), or hormone overproduction (HYPERTHYROIDISM). Goiter may be congenital or acquired, sporadic or endemic (GOITER, ENDEMIC).
Hair Cells, Auditory, Outer
Sensory cells of organ of Corti. In mammals, they are usually arranged in three or four rows, and away from the core of spongy bone (the modiolus), lateral to the INNER AUDITORY HAIR CELLS and other supporting structures. Their cell bodies and STEREOCILIA increase in length from the cochlear base toward the apex and laterally across the rows, allowing differential responses to various frequencies of sound.
A group of inherited conditions characterized initially by HEMATURIA and slowly progressing to RENAL INSUFFICIENCY. The most common form is the Alport syndrome (hereditary nephritis with HEARING LOSS) which is caused by mutations in genes for TYPE IV COLLAGEN and defective GLOMERULAR BASEMENT MEMBRANE.
Bulbar Palsy, Progressive
A motor neuron disease marked by progressive weakness of the muscles innervated by cranial nerves of the lower brain stem. Clinical manifestations include dysarthria, dysphagia, facial weakness, tongue weakness, and fasciculations of the tongue and facial muscles. The adult form of the disease is marked initially by bulbar weakness which progresses to involve motor neurons throughout the neuroaxis. Eventually this condition may become indistinguishable from AMYOTROPHIC LATERAL SCLEROSIS. Fazio-Londe syndrome is an inherited form of this illness which occurs in children and young adults. (Adams et al., Principles of Neurology, 6th ed, p1091; Brain 1992 Dec;115(Pt 6):1889-1900)
An oval, bony chamber of the inner ear, part of the bony labyrinth. It is continuous with bony COCHLEA anteriorly, and SEMICIRCULAR CANALS posteriorly. The vestibule contains two communicating sacs (utricle and saccule) of the balancing apparatus. The oval window on its lateral wall is occupied by the base of the STAPES of the MIDDLE EAR.
The hearing and equilibrium system of the body. It consists of three parts: the EXTERNAL EAR, the MIDDLE EAR, and the INNER EAR. Sound waves are transmitted through this organ where vibration is transduced to nerve signals that pass through the ACOUSTIC NERVE to the CENTRAL NERVOUS SYSTEM. The inner ear also contains the vestibular organ that maintains equilibrium by transducing signals to the VESTIBULAR NERVE.
National Institute on Deafness and Other Communication Disorders (U.S.)
The brain stem nucleus that receives the central input from the cochlear nerve. The cochlear nucleus is located lateral and dorsolateral to the inferior cerebellar peduncles and is functionally divided into dorsal and ventral parts. It is tonotopically organized, performs the first stage of central auditory processing, and projects (directly or indirectly) to higher auditory areas including the superior olivary nuclei, the medial geniculi, the inferior colliculi, and the auditory cortex.
Variations in genetic assessment and recurrence risks quoted for childhood deafness: a survey of clinical geneticists. (1/1607)We report here the results of a questionnaire survey of consultant clinical geneticists in the United Kingdom to which we had an 81% response rate. In this questionnaire we asked about: (1) the nature of services currently offered to families with hearing impaired children, (2) what recurrence risks they quoted in isolated non-syndromic cases, and (3) what they might suggest for improving the range of genetic services available at present. We noted great variation both in these services and in the recurrence risks quoted in isolated cases. Based on the results of the questionnaire, we have proposed a protocol for the investigation of permanent childhood hearing impairment, which we believe to be both comprehensive and practical in an outpatient clinic setting. It is only by improving existing clinical and social understanding and knowledge of childhood hearing impairment that it will become possible to use recent molecular advances to develop comprehensive and consistent services for these families.

Human deafness dystonia syndrome is a mitochondrial disease. (2/1607)The human deafness dystonia syndrome results from the mutation of a protein (DDP) of unknown function. We show now that DDP is a mitochondrial protein and similar to five small proteins (Tim8p, Tim9p, Tim10p, Tim12p, and Tim13p) of the yeast mitochondrial intermembrane space. Tim9p, Tim10p, and Tim12p mediate the import of metabolite transporters from the cytoplasm into the mitochondrial inner membrane and interact structurally and functionally with Tim8p and Tim13p. DDP is most similar to Tim8p. Tim8p exists as a soluble 70-kDa complex with Tim13p and Tim9p, and deletion of Tim8p is synthetically lethal with a conditional mutation in Tim10p. The deafness dystonia syndrome thus is a novel type of mitochondrial disease that probably is caused by a defective mitochondrial protein-import system. (+info)
Contralateral deafness following unilateral suboccipital brain tumor surgery in a patient with large vestibular aqueduct--case report. (3/1607)A 68-year-old female developed contralateral deafness following extirpation of a left cerebellopontine angle epidermoid cyst. Computed tomography showed that large vestibular aqueduct was present. This unusual complication may have been caused by an abrupt pressure change after cerebrospinal fluid release, which was transmitted through the large vestibular aqueduct and resulted in cochlear damage.

Inner ear and kidney anomalies caused by IAP insertion in an intron of the Eya1 gene in a mouse model of BOR syndrome. (4/1607)A spontaneous mutation causing deafness and circling behavior was discovered in a C3H/HeJ colony of mice at the Jackson Laboratory. Pathological analysis of mutant mice revealed gross morphological abnormalities of the inner ear, and also dysmorphic or missing kidneys. The deafness and abnormal behavior were shown to be inherited as an autosomal recessive trait and mapped to mouse chromosome 1 near the position of the Eya1 gene. The human homolog of this gene, EYA1, has been shown to underly branchio-oto-renal (BOR) syndrome, an autosomal dominant disorder characterized by hearing loss with associated branchial and renal anomalies. Molecular analysis of the Eya1 gene in mutant mice revealed the insertion of an intracisternal A particle (IAP) element in intron 7. The presence of the IAP insertion was associated with reduced expression of the normal Eya1 message and formation of additional aberrant transcripts. The hypomorphic nature of the mutation may explain its recessive inheritance, if protein levels in homozygotes, but not heterozygotes, are below a critical threshold needed for normal developmental function. The new mouse mutation is designated Eya1(bor) to denote its similarity to human BOR syndrome, and will provide a valuable model for studying mutant gene expression and etiology. (+info)
Defective high-affinity thiamine transporter leads to cell death in thiamine-responsive megaloblastic anemia syndrome fibroblasts. (5/1607)We have investigated the cellular pathology of the syndrome called thiamine-responsive megaloblastic anemia (TRMA) with diabetes and deafness. Cultured diploid fibroblasts were grown in thiamine-free medium and dialyzed serum. Normal fibroblasts survived indefinitely without supplemental thiamine, whereas patient cells died in 5-14 days (mean 9.5 days), and heterozygous cells survived for more than 30 days. TRMA fibroblasts were rescued from death with 10-30 nM thiamine (in the range of normal plasma thiamine concentrations). Positive terminal deoxynucleotide transferase-mediated dUTP nick end-labeling (TUNEL) staining suggested that cell death was due to apoptosis. We assessed cellular uptake of [3H]thiamine at submicromolar concentrations. Normal fibroblasts exhibited saturable, high-affinity thiamine uptake (Km 400-550 nM; Vmax 11 pmol/min/10(6) cells) in addition to a low-affinity unsaturable component. Mutant cells lacked detectable high-affinity uptake. At 30 nM thiamine, the rate of uptake of thiamine by TRMA fibroblasts was 10-fold less than that of wild-type, and cells from obligate heterozygotes had an intermediate phenotype. Transfection of TRMA fibroblasts with the yeast thiamine transporter gene THI10 prevented cell death when cells were grown in the absence of supplemental thiamine. We therefore propose that the primary abnormality in TRMA is absence of a high-affinity thiamine transporter and that low intracellular thiamine concentrations in the mutant cells cause biochemical abnormalities that lead to apoptotic cell death.

Allele specific oligonucleotide analysis of the common deafness mutation 35delG in the connexin 26 (GJB2) gene. (6/1607)Despite the large number of genes that are expected to be involved in non-syndromal, recessive deafness, only a few have been cloned. One of these genes is GJB2, which encodes connexin 26. A frameshift mutation in this gene has been reported to be common in several populations and a carrier frequency of about 1 in 30 people has been detected in Italy and Spain. Mutation 35delG is difficult to detect because it lies within a stretch of six guanines flanked by thymines, so the deletion of one G does not create or destroy a restriction site and mutagenesis primers are not useful for this mutation. We have generated an allele specific oligonucleotide method that uses 12-mer oligonucleotides and easily discriminates between the normal and 35delG alleles. The method should permit a rapid analysis of this mutation in congenital cases (recessive or sporadic), including diagnosis and carrier detection of 35delG in the population. (+info)
A comparison of language achievement in children with cochlear implants and children using hearing aids. (7/1607)English language achievement of 29 prelingually deaf children with 3 or more years of cochlear implant (CI) experience was compared to the achievement levels of prelingually deaf children who did not have such CI experience. Language achievement was measured by the Rhode Island Test of Language Structure (RITLS), a measure of signed and spoken sentence comprehension, and the Index of Productive Syntax (IPSyn), a measure of expressive (signed and spoken) English grammar. When the CI users were compared with their deaf age mates who contributed to the norms of the RITLS, it was found that CI users achieved significantly better scores. Likewise, we found that CI users performed better than 29 deaf children who used hearing aids (HAs) with respect to English grammar achievement as indexed by the IPSyn. Additionally, we found that chronological age highly correlated with IPSyn levels only among the non-CI users, whereas length of CI experience was significantly correlated with IPSyn scores for CI users. Finally, clear differences between those with and without CI experience were found by 2 years of post-implant experience. These data provide evidence that children who receive CIs benefit in the form of improved English language comprehension and production. (+info)
Can routine information systems be used to monitor serious disability? (8/1607)OBJECTIVE: To determine whether reliable birth cohort prevalence rates of disabling conditions in early childhood can be obtained from child health information systems. DESIGN: Comparison of two sources of information on motor and sensory disabilities: from child health information systems held by health authorities, and a population register that uses multiple sources of ascertainment. SETTING: The counties of Oxfordshire, Buckinghamshire, and Northamptonshire. PARTICIPANTS: Children born to residents of the three counties between 1984 and 1989. RESULTS: Eight hundred and twenty children (6.0/1000 live births) were identified from the child health system as having one or more of the conditions, and 580 (4.2/1000 live births) were identified from the population register; however, only 284 children were identified by both sources. CONCLUSIONS: It is currently impossible to monitor trends in the prevalence rate of disabling disorders in childhood using the child health information systems. Agreement about ways of collecting, recording, and collating information on disability would be a useful step towards realising the full potential of these systems. (+info)

Mutations in the myosin VIIA gene cause non-syndromic recessive deafness | Nature Genetics
Genetic hearing impairment affects around 1 in every 2,000 births1. The bulk (approximately 70%) of genetic deafness is non-syndromic, in which hearing impairment is not associated with any other abnormalities. Over 25 loci involved in non-syndromic deafness have been mapped and mutations in connexin 26 have been identified as a cause of non-sydromic deafness2. One locus for non-syndromic recessive deafness, DFNB2 (ref. 4), has been localized to the same chromosomal region, 11q14, as one of the loci, USH1B, underlying the recessive deaf-blind syndrome. Usher syndrome type 1b, which is characterized by profound congenital sensorineural deafness, constant vestibular dysfunction and prepubertal onset of retinitis pigmentosa. Recently, it has been shown that a gene encoding an unconventional myosin, myosin VIIA, underlies the mouse recessive deafness mutation, shaker-1 (ref. 5) as well as Usher syndrome type 1b6. Mice with shaker-1 demonstrate typical neuroepithelial defects manifested by hearing loss and
Prelingual deafness - Wikipedia
A prelingual deaf individual is someone who was born with a hearing loss, or whose hearing loss occurred before they began to speak. Infants usually start saying their first words around one year. Therefore a prelingually deaf typically was either born deaf or lost their hearing before the age of one (the age when most hearing loss in children occurs). Congenital (present at birth) hearing loss is also considered prelingually, since a newborn infant has not acquired speech and language. Each year in the United States, approximately 12,000 babies are born with hearing loss. Profound hearing loss occurs in somewhere between 4 to 11 per every 10,000 children. Prelingual hearing loss can be either acquired, meaning it occurred after birth due to illness or injury, or it can be congenital, meaning it was present at birth. Congenital hearing loss can be caused by genetic or nongenetic factors. The nongenetic factors account for about one fourth of the congenital hearing losses in infants. These ...

N2 - The consequences of deafness on the central auditory nervous system have been examined at many levels, from molecular to functional. However, there has never been a direct and selective measurement of excitatory synaptic function following total hearing loss. In the present study, gerbils were deafened at postnatal day 9, an age at which there is no deafferentation-induced cell death of ventral cochlear nucleus neurons. One to five days after bilateral cochlear ablation, the amplitude of evoked excitatory postsynaptic currents (EPSC) was measured with whole-cell voltage-clamp recordings in an inferior colliculus (IC) brain slice preparation in response to electrical stimulation of the ipsilateral lateral lemniscus (LL) or the commissure of the inferior colliculus (CIC). Deafness resulted in larger LL- and ...

Congenital Deafness in Dogs - SitStay
It is not possible to prevent congenital deafness from occurring, and this is the reason why dogs who are deaf should not be bred. For dogs who are not deaf, it is important to have their ears checked every six months to make sure they are healthy. If something like an ear infection is left untreated, it can lead to chronic changes in the ears that can increase the risk of acquired deafness in the future.. Many deaf dogs go on to lead normal lives, and there are generally no additional underlying illnesses when it comes to congenital deafness. If anything, dogs with fair hair coat colors may be more susceptible to sunburns. Therefore, sunblock is important when these dogs go outside.. Deaf dogs can be trained using hand signals and body language, and their sense of smell will help dogs who are treated motivated. If training is initially difficult, you can contact a trainer who specializes in working with deaf dogs. It is also important to remember that deaf dogs should not walk off-leash because ...
OSA | Communication modes applied to axicons
The communication modes, which constitute a convenient method for the propagation and information analysis of optical fields, are formulated in the generalized axicon geometry. The transmitting region is the axicons annular aperture, and the observation domain is the optical axis containing the focal line segment. We show that in rotational symmetry one may employ the prolate spheroidal wave functions to represent the communication modes. Further, in usual circumstances the modes can be approximated by quadratic waves in the aperture domain and by sinc functions in the image domain. Both the exact communication modes and the approximate technique are confirmed numerically, with linear axicons as examples.. ©2004 Optical Society of America. Full Article , PDF Article ...
Modifiers of deafness genes - Gynecology - Ormed Medical Exchange
Several modifier genes have been localised that modify the phenotype of carriers of known deafness genes. In humans, a dominant modifier has been reported to suppress deafness in people homozygous for the DFNB26 recessive deafness locus (Riazuddin et al., 2000). Two modifiers have been proposed to influence the hearing loss observed in carriers of the A1555G mitochondrial mutation associated with progressive hearing loss, a locus on chromosome 8 near D8S277 and a locus on chromosome 6 near the TFB1M gene (Bykhovskaya et al., 2000; 2004). In the mouse, three modifiers of deafness genes have been identified. The first is moth1, which has a major effect upon the hearing of tubby mutant homozygotes (tub/tub), and has been identified as a variant of the Mtap1 gene. A second is mdfw, modifier of deaf waddler, which largely determines whether heterozygous carriers of a deaf waddler mutation (+/Atp2b2dfw2J) show progressive hearing loss or not. This modifier is most likely to be a synonymous single ...
Congenital deafness (CD) is a condition of impaired hearing due to genetic or pregnancy-related causes in infants with a highly variable onset of initial symptoms. Genetic CD is most probably related with pathological gene mutations while acquired CD normally correlates with irregularities during pregnancy. Thorough screening for temporal bone malformations and a detailed family background check in combination with molecular genetic tests yield a reliable diagnosis. A multidisciplinary team of medical professionals and educators is necessary to support infant patients and their parents.… Congenital Deafness: Read more about Symptoms, Diagnosis, Treatment, Complications, Causes and Prognosis.

Advances in the Genetics of Deafness : The Oxford Handbook of Deaf Studies, Language, and Education, Volume 1, Second Edition -...
Genetic factors are believed to account for more than half of all cases of congenital or early-onset moderate to profound deafness. The identification of several dozen genes for deafness, one of which accounts for a high proportion of all childhood deafness, has enabled the identification of the exact cause of deafness in many children through genetic testing. Parents, family members, deaf and hard-of-hearing adults, as well as health care and educational professionals often are unaware of the exact process and goals of genetic evaluation and may have questions about the usefulness of genetic testing. Sensitive and appropriate genetic evaluation and testing, coupled with appropriate interpretation and information through genetic counseling, can be invaluable to many families. Health professionals and those who work with deaf children in educational and service settings play an important role in helping parents and family members understand the value of a genetic evaluation and making referrals ...

Deaf Animals: November 2007
First, allow me to explain how I ended up knowing about this deaf cat. A deaf woman, Lisa Ramey, from Phoenix, AZ, stumbled upon this 1.5 year old deaf cat on craigslist where this hearing owner was in hurry to get rid of him and contacted Deaf Animal Row. There was never a picture shown of the cat at all. In his own words, his deaf cat wont stop playing when his hearing cat hissed. Whats the crime of having a playful cat? He just wants his deaf cat out without the consideration nor sensitivity when it comes to accomodating and training a deaf cat. Interesting how a deaf cat has to be the one to go. Doesnt it sound familiar that being deaf is used as a scapegoat for everything that goes wrong? He has never and do not want to name the deaf cat because he cant hear his own name. Oh, does it mean we, deaf people, ought be nameless as well? Wasnt he aware about name sign thats prevalent in the Deaf community? When one uses the sign name daily to a deaf cat or dog, some deaf cats and dogs will ...
Epidemiology of Non-syndromic Dominant Deafness - Full Text View - ClinicalTrials.gov
Hearing impairment is a common disorder that affects at least 7% of individuals in our countries. Even the causes of hearing impairment are numerous, genetic causes represent the main factor of sensorineural deafness. Among hereditary non-syndromic deafness autosomal-dominant inheritance is observed in about 10-20% of the cases. These forms of deafness are usually post-lingual and progressive. To date more than 41 chromosomal localisation and 21 genes associated to non syndromic dominant deafness have been described. It represents an extreme genetic heterogeneity making difficult the studies of these forms of hearing impairment. But, genetic diagnostic testing is crucial in these cases. Indeed, therapeutic research are in the way to prevent the progression of the disorder. The aim of this work is to establish the prevalence of the different genes involved in these forms of deafness ...

Scientists Develop New Gene Therapy For Deafness - Wise Hearing
Delivering healthy genetic material into the inner ear cells of mice with a genetic defect that causes deafness enables the cells to function normally, according to a new study from Tel Aviv University (TAU).. The novel treatment prevented the gradual deterioration of hearing in these mice. It could lead to a breakthrough in treating children born with various mutations that eventually cause deafness. The study, led by Prof. Karen Avraham of the Department of Human Molecular Genetics and Biochemistry at TAUs Sackler Faculty of Medicine and Sagol School of Neuroscience, was published in EMBO Molecular Medicine on December 22.. Deafness is the most common sensory disability worldwide. According to the World Health Organization, about half a billion people have hearing loss and this figure is expected to double in the coming decades.. One in every 200 children is born with a hearing impairment, and one in every 1,000 is born deaf. In about half of these cases, deafness is caused by a genetic ...

Reporter 450, 3 April 2000
Studies at the University and St James s University Hospital have succeeded in identifying some of the genes involved in inherited hearing impairment. The ground-breaking research has brought scientists closer to the technical feasibility of pre-natal testing for inherited deafness - raising profound ethical issues, which the Leeds investigators are determined not to side-step.. Genetic studies, benefiting from the co-operation of a group of inter-related families in West Yorkshire, have been accompanied by a study of the attitudes of deaf people towards gene science.. Anna Middleton has just completed a doctoral thesis, involving a nationwide survey of deaf people s own views on such issues as whether pre-natal testing for deafness would be seen as a step forward.. Many deaf adults who use sign language, take pride in their difference and reject the notion of deafness as a pathological impairment - see pre-natal diagnosis as a threat to their long-term existence as a community. The overwhelming ...

Claims for industrial deafness have surged in the past five years amid fears that it has become a new hunting ground for claims management firms and personal injury lawyers.. Days after the Association of British Insurers warned that industrial deafness had become a new cash cow for the legal profession, leading insurers have published figures that deepen such concerns.. RSA, operator of the More Than brand, said that it had received more than 800 new claims for industrial deafness every month last year, almost double the 450 a month coming in two years previously. The company, which believes that the system is being exploited, said that it rejected about 70 per cent of all of the claims that came in.. Deafness is a major issue for the insurance industry, a spokeswoman said. It is certainly true that we have seen an increase in industrial deafness claims over recent years..

EGL Genetics | About EGL Genetics
In the United States, approximately 1 in 1000 children are diagnosed with prelingual hearing loss (HL) or deafness. Approximately half of prelingual hearing loss or deafness is attributed to environmental exposures and the remaining half to genetic causes. Approximately 30% of hereditary hearing loss is estimated to be syndromic (associated with other birth defects) while the remaining 70% is non-syndromic (isolated and not associated with other findings). Non-syndromic deafness is mainly due to recessive genes (75-80%) and over 20 such genes have been identified, but non-syndromic deafness may also be inherited in autosomal dominant, X-linked, or mitochondrial patterns.. Molecular testing can aid in rapid diagnosis of hearing loss. Early diagnosis of hearing defects can provide diagnostic information, facilitate timely intervention, and assist with genetic counseling.. Connexins are transmembrane proteins that form channels that allow rapid transport of small molecules between cells; the ...
Protein Found Responsible For Some Genetic Deaf...
Some people lose their hearing because they simply age; some because of too much loud noise. For some, the ability to hear never developed.Researchers at the Scripps Research Institute in La Jolla, Calif., have discovered a protein that is responsible for one form of genetic deafness. The protein helps turn sound into electrical signals.The research is of more than just biochemical interest; it may also open a new avenue for possibly giving the sense of hearing to some of those who are born without it. The team, led by Ulrich Mueller, a professor of cell biology, took newborn deaf mice and inserted the protein, called TMHS, into their sensory cells for sound perception, giving the mice some form of hearing. The potential now exists for genetic therapy to insert the genes for the protein into newborn humans and fix malfunctioning cells. The work is published in the Dec. 7, 2013 issue of the journal Cell.No one knows how many people suffer from genetic deafness but they surely
Models of deafness | Canadian Hearing Services
Language is a powerful tool. It both shapes and is shaped by ideas, perceptions and attitudes. And its these very attitudes that can pose the most difficult barriers for people who are culturally Deaf, oral, deafened, and hard of hearing.. There are three main models of deafness that affect an individuals perspectives, interactions, self-identification and, ultimately, their worldview: medical, social and cultural.. Medical model - Focuses on the medical/pathological condition of the individual - a functional loss, handicap or impairment that needs medical intervention and rehabilitation to increase ones quality of life. Common terms used in the past to describe the deaf or hard of hearing individual or their physical state using this model include disabled, hearing impaired, and deafness. Nowadays, such terms are considered antiquated and offensive in the Deaf community..

New research identifies key mechanism behind some deafness - Scienmag: Latest Science and Health News
Dr. Ahmed and his colleagues are now looking for other molecules beyond CIB2 that play a key role in the process. In addition, they are exploring potential therapies for CIB2-related hearing problems. In mice, they are using the gene editing tool CRISPR to modify dysfunctional CIB2 genes. They suspect that if this modification occurs in the first few weeks after birth, these mice, which are born deaf, will be able to hear. The scientists are also experimenting with gene therapy, using a harmless virus to deliver a normal copy of the normal CIB2 gene to baby mice that have the mutated version. Dr. Ahmed says the early results of these experiments are intriguing.. Nearly 40 million Americans suffer from some level of hearing loss. This includes around 74,000 children with profound, early-onset deafness. At least 50 percent of these deafness cases are due to genetic causes. It is not clear how common CIB2 mutations are in the US population, or how large a role these mutations play in deafness in ...

Models of deafness - Wikipedia
Various models of deafness are rooted in either the social or biological sciences. These are the medical (or infirmity) model, the social model, and the cultural model. The model used can affect how deaf persons are treated and their identity. In the medical model, deafness is viewed as an undesirable condition, to be so treated. Within the social model, the design of the deaf persons environment is viewed as the major disabling factor. In the cultural model, the Deaf belong to a culture in which they are neither infirm nor disabled. Physicians and scientists are often labeled as adherents of the medical model by Deaf individuals, who contrast it with their own cultural model. However, many of those who are so labeled dispute its validity. The social model seeks to illuminate the difficulties that deaf individuals face in their social environment. The medical model of deafness is viewed by advocates for the deaf[who?] as originating from medical, social welfare and majority ...

Introduction: Deaf people who use American Sign Language (ASL) comprise linguistic and cultural minority populations without access to language-concordant health information and healthcare. Deaf ASL users are rarely included in health research or public health surveillance. Recent research with Deaf ASL users found a higher prevalence of obesity than in the general population. No randomized trials of lifestyle modification or weight reduction have ever been attempted with Deaf ASL users.. Methods: We worked with the Rochester (NY) Deaf community to adapt a 16-week healthy lifestyle program previously shown to be effective with hearing people. We adapted the curriculum and research measures to be culturally and linguistically appropriate. We used a group intervention format recommended by our Deaf partners, and trained group leaders who were Deaf, ASL fluent and had backgrounds in counseling, public health, or healthcare. For this Deaf Weight Wise (DWW) trial, we recruited Deaf adults aged 40-70 ...

My attitudes and perspectives about young deaf children getting cochlear implants have gradually evolved since the first time I heard about deaf people getting cochlear implants. Growing up with deaf parents and attending deaf schools, I have a strong sense of pride of being deaf and being part of the Deaf community. I do not look at myself as disabled. I often say if I were given a choice to hear or stay deaf, I d choose to stay deaf. It is who I am. My family, my friends, and my community have taught me that being deaf is part of our culture and is a way of life. Many deaf people have succeeded in life without having the ability to hear. They ve become lawyers, doctors, scientists, and teachers. It has nothing to do with the ability to hear. It has to do with many other factors such as the person s attitude, values, beliefs, and motivation.. I used to oppose strongly the idea of deaf people getting cochlear implants. It indicates the need to fix the problem. I felt betrayed and angry that ...

Medical News Today: Innovative gene editing method may prevent deafness | EDクリニック.INFO
According to data from the National Institute on Deafness and Other Communication Disorders, around two to three children in every 1,000 in the United States are born with a hearing impairment in one or both ears, and about 15 percent of adults have hearing problems.. Moreover, the Centers for Disease Control and Prevention (CDC) note that 50 to 60 percent of hearing loss cases in babies are due to genetic factors, caused by the mutation of genes that program hearing.. Recently, scientists have been experimenting with genome editing methods in the hope that they would be able to manipulate it so as to prevent the onset of total deafness due to genetic factors.. Researchers at the Howard Hughes Medical Institute in Chevy Chase, MD, have now used precise genome editing technology called CRISPR-Cas9 on a mouse model to remove a gene variant that can lead to total loss of hearing..

Deafness and being hard of hearing | girlshealth.gov
A hearing aid is a small electronic device that you wear in or behind your ear. It works like a tiny amplifier, making sounds louder. It can take time to get used to a hearing aid. You also may need to have some adjustments done to your hearing aid so it works well for you. A cochlear implant (say: KOK-lee-uhr IM-plant) is a tiny electronic device that is put into the part of your ear called the cochlea. It takes over the job of damaged parts of your ear. The implant is recommended only if hearing aids dont help enough.. Getting a cochlear implant can be a big decision. It requires surgery, and it doesnt give back all your hearing. It also takes time to learn to understand the sounds an implant makes. And some people feel that deafness doesnt need to be fixed. They feel that deafness offers deaf culture, which connects deaf people through a shared language, history, and experiences. ...
A Charity for Deafness Guidance
When you organize a charity, even medical science may need a hand. The gift of medicine and helping out people who may have some deficiencies on their health is pretty much a growing concern and considering that many people today are suffering in terms of seeking medication and assistance for various health issues, good causes such as charities are a great way to help them out. One of these medical problems deals with hearing. The number of people who suffer from deafness is apparent and while there are medical solutions to it, they do not come cheap. Some have to console themselves with the fact that money talks and unless some good soul or program is raised, the inevitable task of enjoying the sense of hearing will only remain a goal for them. In a move not to really help cure deafness immediately, worthy causes such as the ones being undertaken by the charity Deafness Research UK can do their small part by distributing pamphlets and guiding people suffering from deafness. In the pamphlets, ...
dnd 5e - If you cast Blindness/Deafness as a 3rd level spell, can you target one creature with both effects? - Role-playing...
The Players Handbook states that when cast as a 3rd level or higher spell, Blindness/Deafness can target additional targets equal to the difference between the spell slot the spell is cast at and its base spell slot level of 2.. My question is, would it be legal to cast Blindness/Deafness as a 3rd level spell, but instead of having either effect (blindness OR deafness) target two creatures, have it target one creature with both effects (blindness AND deafness.). Im having a hard time deciding whether this would provide an overpowered effect, as it increases the amount of disabilities one creature will suffer from, but lessens the number of creatures affected by the spell.. Perhaps it could be legal provided the targeted creature gets to make a separate CON save against each effect?. ...
Faster phonological processing and right occipito-temporal coupling in deaf adults signal poor cochlear implant outcome |...
The outcome of adult cochlear implantation is predicted positively by the involvement of visual cortex in speech processing, and negatively by the cross-modal recruitment of the right temporal cortex during and after deafness. How these two neurofunctional predictors concur to modulate cochlear implant (CI) performance remains unclear. In this fMRI study, we explore the joint involvement of occipital and right hemisphere regions in a visual-based phonological task in post-lingual deafness. Intriguingly, we show that some deaf subjects perform faster than controls. This behavioural effect is associated with reorganized connectivity across bilateral visual, right temporal and left inferior frontal cortices, but with poor CI outcome. Conversely, preserved normal-range reaction times are associated with left-lateralized phonological processing and good CI outcome. These results suggest that following deafness, involvement of visual cortex in the context of reorganized right-lateralized phonological

Deafness/Hearing Impairment - MIND
People who are hard of hearing may have been born with a hearing loss or subsequently experienced a partial loss of hearing. While they have acquired speech normally through hearing and communicate by speaking, their speech may be affected. Their voice may be too soft or too loud. They understand others by speech reading, by the use of a hearing aid, or by asking the speaker to raise his or her voice or enunciate more distinctly.. Sign language is used primarily by deaf people throughout the world. It differs from spoken languages in that it is visual rather than auditory, and is composed of precise handshapes and movements. This language has evolved in a completely different medium, using the hands and face rather than the voice. It is perceived by the eye rather than the ear. Sign language is not a universal language shared by deaf people of the world. There are many sign languages that have evolved independently of each other. Sign language portrays the image, identity and culture of the ...

The Deaf Experience: Classics in Language and Education - Google Books
The seminal study of the antecedents of Deaf culture is now back in print. Edited by renowned scholar Harlan Lane, The Deaf Experience: Classics in Language and Education presents a selection of the earliest essays written by members of the nascent French Deaf community at the time of the Enlightenment, a rich period of education for deaf people. The fifth volume in the Gallaudet Classics in Deaf Studies series features works written from 1764 up to1840. Pierre Desloges offers a stirring paean to sign language in an excerpt from his book, the first ever published by a deaf person. Saboureux de Fontenay and Jean Massieu, two prominent leaders, relate their respective experiences in autobiographical accounts. In separate essays, Charles-Michel de lEp e and Roch-Ambroise Sicard describe systems for teaching manual French, followed by a critique of these methods by Roch-Ambroise B bian, a well-known hearing friend of Deaf people during that era.

International Sign - Wikipedia
Deaf people in the Western and Middle Eastern world have gathered together using sign language for 2,000 years. When Deaf people from different sign language backgrounds get together, a contact variety of sign language arises from this contact, whether it is in an informal personal context or in a formal international context. Deaf people have therefore used a kind of auxiliary gestural system for international communication at sporting or cultural events since the early 19th century. The need to standardise an international sign system was discussed at the first World Deaf Congress in 1951, when the WFD was formed. In the following years, a pidgin developed as the delegates from different language backgrounds communicated with each other, and in 1973, a WFD committee (the Commission of Unification of Signs) published a standardized vocabulary. They selected naturally spontaneous and easy signs in common use by deaf people of different countries to make the language easy to learn. A ...
Harry Potter, muggles…and deafness - I Sign. I Wander.
Why?. You see, Hermione is a Muggle born.. I did not know why I was able to connect with her…until a friend sent me this amazing academic article - Understanding Harry Potter: Parallels to the Deaf World, written by Todd Czubek and Janey Greenwald.. It blew me away. At last, I was able to explain why Hermione and I were similar.. I was born to hearing parents - just like Hermione was born to Muggle parents. 90% of Deaf children are born to hearing parents who have had no or little exposure to Deaf people and/or the Deaf community. Just like the majority of wizard children being born to Muggle parents.. Deaf children who are born into Deaf families could be considered Purebloods - a full wizarding family.. Deaf children who are born to one hearing parent and one deaf parent respectively could be considered Half-bloods, in which are born to one Muggle parent and one Wizard parent respectively.. Hermiones parents actively encouraged her to embrace her magical abilities by sending her off to ...

5pSC32 Intersyllabic regulation of F0 and SPL with and without auditory
Jane Wozniak Harlan Lane Joyce Manzella Joseph Perkell Melanie Matthies Mario Svirsky Michael OConnell Clay Mitchell Res. Lab. of Electron., Rm. 36-511, MIT, Cambridge, MA 02139 Syllable-to-syllable fluctuation of F0 and SPL were measured in readings of a passage by 4 post-lingually deafened adults, recorded before and after they received cochlear implants, and one adult with neurofibromatosis-2 (NF2), who was initially profoundly deaf in one ear and had a mild to moderate hearing loss in the other (aided). Three of the 4 cochlear implant users reliably reduced syllable-to-syllable fluctuation in F0 and SPL following the activation of their speech processors. The fourth speaker began with and maintained the regularity achieved by the others post-activation. In recordings made following the onset of bilateral profound deafness, the NF2 subject showed increased syllable-to-syllable fluctuation in F0 and SPL. Results from another experiment [M. A.

Research at NTID | National Technical Institute for the Deaf | RIT
The Deaf Studies Laboratory investigates cognitive, linguistic and social aspects of the Deaf Experience. It aims to bring more deaf individuals into a variety of fields of research in an American Sign Language-based student-centered environment, partnering with many universities and centers nationally and internationally.. The Collaboratory on Economic, Demographic and Policy Studies seeks to describe the demographic and economic conditions of the deaf and hard-of-hearing population in the U.S., with emphasis on the impact education has on improving these conditions.. The deaf x laboratory conducts research on brain reorganization in the face of altered sensory input, asking what happens to the brain areas and neural pathways associated with visual and multi-sensory processing when auditory input is missing. While housed in NTID, psychology majors have the opportunity to participate as research assistants on projects in deaf x laboratory. ...

On a worldwide basis, there are only a few case reports of otopathology in patients with genetic deafness where the precise genetic mutation was known. Given the variant clinical expressions of syndromes of genetic deafness, it becomes urgent to provide pathologic profiles that can be matched to the genetic abnormalities. Without this knowledge, it will be difficult to ultimately devise strategies for overcoming the genetic defects. Animal models, including knockouts, knockins, and naturally occurring mutants are being increasingly used to investigate the genetics of hearing loss. Such models can provide valuable information regarding the molecular bases of auditory and vestibular disorders, but remains important to verify the validity of these models by comparison with the otopathology as determined in human cases ...

AKC Canine Health Foundation
Congenital deafness is a health issue that has higher prevalence in certain breeds, including the Dalmatian. Other studies in this breed have found the trait to be inherited in a complex rather than simple Mendelian manner. Using a large number of samples from animals that have been tested for hearing status, Dr. Wade will employ the latest genomic technologies and computational analyses to conduct this study. The ultimate goal is to identify mutations underlying the trait of congenital deafness in the Dalmatian breed and work towards a genetic testing solution for the Dalmatian breeding community. Funding for the research is provided through the efforts and generosity of the Dalmatian Club of America Foundation. The AKC Canine Health Foundation supports the funding of this effort and will oversee administration of funds and scientific progress reports.

New recipe for antibiotic could prevent deafness - Relic Time
A new method of purifying gentamicin, a widely used antibiotic, reduces the risk that it will cause deafness, according to a Stanford Medicine-led study.. Gentamicin is used in U.S. hospitals to treat a variety of bacterial infections, including infections in newborns and in other susceptible patients, such as those with cystic fibrosis. Its a popular drug in developing countries because it is highly effective and inexpensive. Yet researchers estimate that up to 20% of patients who are treated with it experience some degree of irreversible hearing loss.. Now, researchers have found a relatively inexpensive way to reformulate the drug, which belongs to a class of antibiotics called aminoglycosides, to be safer. Their findings were published Dec. 7 in the Proceedings of the National Academy of Sciences.. When a drug causes hearing loss, it is devastating, and its especially disturbing when it happens to a young child, as they rely on hearing to acquire speech, said Alan Cheng, MD, a professor ...
The effects of early auditory deprivation - insights from children with cochlear implants
This update explores the importance of early auditory stimulation by considering the development of speech processing skills in profoundly deaf children who have received a cochlear implant. This literature is relevant to issues affecting children with Down syndrome, because like them, children with cochlear implants have hearing difficulties, but unlike the former, they do not have oral-motor issues.
Deaf children learn words faster than hearing children | EurekAlert! Science News
Each year many deaf children get a cochlear implant to connect to the world of sounds. So far, it was not clear which processes take place in these children when they start to learn language -- and why they differ in the level of language they achieve. Now, the Max Planck Institute for Human Cognitive and Brain Sciences found that deaf children with a cochlear implant learn words even faster than those with normal hearing.

Communication of Oral Deaf and Normally Hearing Children at 36 Months of Age | Journal of Speech, Language, and Hearing...
Eighteen orally educated deaf and 18 normally hearing 36-month-old children were observed in a play session with their mother. Communicative behavior of the child was coded for modality and communicative function. Although the oral deaf children used a normal range of functions, both the quantity and proportions differed from normally hearing children. Whereas the normally hearing 3-year-olds used speech almost exclusively, the deaf children exhibited about equal use of speech, vocalizations, and gestures. Spoken language scores of the deaf children at 5 years of age were best predicted by (a) more frequent use of speech at age 36 months, (b) more frequent use of the Statement function, and (c) relatively infrequent use of the Directive function. It is suggested that some communicative functions are more informative or heuristic than others, and that the early use of these functions is most likely to predict later language competence.. ...
Outcomes of Auditory Brainstem Implantation in Adults with Postlingual by Jillian Friedman
Objective:The purpose of this investigation is to conduct a systematic review of the long-term speech-recognition outcomes of ABIs in postlingually deafened adults, and to compare outcomes of ABIs in adults with NF2/tumors to adults without NF2. Methods: A comprehensive search utilizing various peer reviewed databases via the City University of New York (CUNY) Graduate Center Library was conducted to identify relevant studies investigating speech-recognition outcomes in ABI patients with postlingual deafness, both with and without tumors. Inclusion criteria included studies that involved at least one adult ABI patient (with or without NF2) with postlingual deafness, who was seen for follow-up auditory performance testing at one-year post-activation or later. Results: Thirteen articles met inclusion criteria for this systematic review. The studies utilized various materials for speech-recognition assessment to evaluate speech-recognition performance. Because of the great diversity among the materials
