Methods of hearing loss detection and management throughout the lifespan are highlighted as is a particularly new development in newborn hearing screening. The challenges of hearing loss, an extremely heterogeneous impairment, are addressed. Additional topics include current research interests, ranging from novel gene identification to their functional validation in the mouse and zebrafish. The book ends with a chapter on the state of the art of gene therapy—an area that is certain to gain increasing attention as molecular mechanisms of deafness are better understood. Genetics of Deafness, written by leading authors in the field, is a must read for clinicians, researchers, and students. It provides much needed insight into the diagnosis and research of hereditary hearing loss.

Download or read book The Effects of Genetic Hearing Impairment in the Family written by Dafydd Stephens and published by John Wiley & Sons. This book was released on 2006-10-02 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been an explosion of studies in the field of genetic hearing impairment in the past decade, associated with major advances in our understanding of the mechanisms and conditions involved. However, a recent review has highlighted the very limited number of studies on the effects of such hearing impairment on the individuals and families of those concerned. In The Effects of Genetic Hearing Impairment in the Family, under the aegis of the European Union GENDEAF programme, the editors have taken the first steps to address this deficit in our knowledge and understanding of this topic. The book addresses the problem by secondary analyses of existing large scale population studies, by prospective investigation of individuals with a family history of hearing impairment and by specific studies on patients with otosclerosis and neurofibromatosis 2 and their families. In addition several chapters look at the specific impact of deaf culture, ethnicity and religion on reactions to deafness and the specific needs in genetic counselling. This book represents an important first step in this field and should be an invaluable resource for all professionals involved with people with hearing impairments.

Download or read book Impact of Genetic Hearing Impairment written by Dafydd Stephens and published by John Wiley & Sons. This book was released on 2005 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the impact of genetic deafness/hearing impairment on people' s lives and those around them. It includes the perspectives of those who are deaf or hard of hearing as well as those working in the field. Professional topics include genetic counselling, social science, psychology, social work and - within medicine - audiological and ENT medical and audiological paediatrics. These practitioners are both hearing and hearing impaired. The impact of deafness on children, those of working age and elderly people is discussed highlighting the specific effect of genetic factors. In particular there are chapters on deafblindness and otosclerosis and NF2 (a potentially lethal condition). The Who definitions and ICF are used as a framework for considering the effect on people' s lives of impairment and their participation in society. This provides a bridge between the medical and social models of disability. Contributors write from both their professional and personal experience in order to try and address some of the issues raised by the real impact of genetic deafness on everyday life and how these can best be tackled by those working in the field.

Download or read book Hearing Health Care for Adults written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-10-06 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: The loss of hearing - be it gradual or acute, mild or severe, present since birth or acquired in older age - can have significant effects on one's communication abilities, quality of life, social participation, and health. Despite this, many people with hearing loss do not seek or receive hearing health care. The reasons are numerous, complex, and often interconnected. For some, hearing health care is not affordable. For others, the appropriate services are difficult to access, or individuals do not know how or where to access them. Others may not want to deal with the stigma that they and society may associate with needing hearing health care and obtaining that care. Still others do not recognize they need hearing health care, as hearing loss is an invisible health condition that often worsens gradually over time. In the United States, an estimated 30 million individuals (12.7 percent of Americans ages 12 years or older) have hearing loss. Globally, hearing loss has been identified as the fifth leading cause of years lived with disability. Successful hearing health care enables individuals with hearing loss to have the freedom to communicate in their environments in ways that are culturally appropriate and that preserve their dignity and function. Hearing Health Care for Adults focuses on improving the accessibility and affordability of hearing health care for adults of all ages. This study examines the hearing health care system, with a focus on non-surgical technologies and services, and offers recommendations for improving access to, the affordability of, and the quality of hearing health care for adults of all ages.

Download or read book Hearing Loss written by National Research Council and published by National Academies Press. This book was released on 2004-12-17 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.

Download or read book Hearing Loss Mechanisms Prevention and Cure written by Huawei Li and published by Springer. This book was released on 2019-03-26 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book systematically discusses the pathogenesis, prevention, and the current and potential clinical treatment of hearing loss, as well as the latest advances in hearing research. Hearing loss is a prevalent sensory disorder, which according to a 2015 World Health Organization (WHO) report affected 9% of the global population in 2015. As populations continue to age, more and more people are suffering from the condition, with 60% of those aged between 65 and 75 affected. Hearing loss seriously affects patients’ ability to work ability and quality of life, and as such deafness has become an increasingly urgent social problem around the globe. Sensorineural hearing loss is mainly caused by damage to the hair cells (HCs), and the subsequent loss of spiral ganglion neurons (SGNs). Damage to the HCs in the inner ear can result from exposure to loud noises and environmental and chemical toxins as well as genetic disorders, aging, and certain medications. This book provides ENT specialists and researchers, as well as individuals affected a comprehensive introduction to the field of hearing loss.

This book was released on 2020-11-04 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hearing impairment is an immensely diagnosed genetic cause, 5% of the total world population effects with different kind of congenital hearing loss (HL). In third-world countries or countries where consanguineous marriages are more common the frequency rate of genetic disorders are at its zenith. Approximately, the incidence of hearing afflictions is ostensibly 7-8:1000 individuals whereas it is estimated that about 466 million peoples suffer with significant HL, and of theses deaf cases 34 million are children's up to March, 2020. Several genes and colossal numbers of pathogenic variants cause hearing impairment, which aided in next-generation with recessive, dominant or X-linked inheritance traits. This review highlights on syndromic and non-syndromic HL (SHL and NSHL), and categorized as conductive, sensorineural and mixed HL, which having autosomal dominant and recessive, and X-linked or mitochondrial mode of inheritance. Many hundred genes involved in HL are reported, and their mutation spectrum becomes very wide. Mapping of pathogenic genes in consanguinity family is facilitated to understand the disease history. Review presents the bases of HL and also focused on various genetic factors that cause deafness like the basics of genetic inheritance, and classic and well-characterized inherited factors of it. It also overviews the application of linkage analysis, SNPs genotyping and whole exome sequencing methods, in mapping and identification of new locus, causative genes and their variants in families inherited with HL. Conclusively, this review supports researchers in understanding the location of chromosome, the causative genes and specific locus which causing deafness in humans.

Download or read book Occupational Noise Exposure written by Department of Health and Human Services and published by Createspace Independent Publishing Platform. This book was released on 2014-02-19 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Occupational Safety and Health Act of 1970, Congress declared that its purpose was to assure, so far as possible, safe and healthful working conditions for every working man and woman and to preserve our human resources. In this Act, the National Institute for Occupational Safety and Health (NIOSH) is charged with recommending occupational safety and health standards and describing exposure concentrations that are safe for various periods of employment-including but not limited to concentrations at which no worker will suffer diminished health, functional capacity, or life expectancy as a result of his or her work experience. By means of criteria documents, NIOSH communicates these recommended standards to regulatory agencies (including the Occupational Safety and Health Administration [OSHA]) and to others in the occupational safety and health community. Criteria documents provide the scientific basis for new occupational safety and health standards. These documents generally contain a critical review of the scientific and technical information available on the prevalence of hazards, the existence of safety and health risks, and the adequacy of control methods. In addition to transmitting these documents to the Department of Labor, NIOSH also distributes them to health professionals in academic institutions, industry, organized labor, public interest groups, and other government agencies. In 1972, NIOSH published Criteria for a Recommended Standard: Occupational Exposure to Noise, which provided the basis for a recommended standard to reduce the risk of developing permanent hearing loss as a result of occupational noise exposure [NIOSH 1972]. NIOSH has now evaluated the latest scientific information and has revised some of its previous recommendations. The 1998 recommendations go beyond attempting to conserve hearing by focusing on preventing occupational noise-induced hearing loss (NIHL). This criteria document reevaluates and reaffirms the recommended exposure limit (REL) for occupational noise exposure established by the National Institute for Occupational Safety and Health (NIOSH) in 1972. The REL is 85 decibels, A-weighted, as an 8-hr time-weighted average (85 dBA as an 8-hr TWA). Exposures at or above this level are hazardous. By incorporating the 4000-Hz audiometric frequency into the definition of hearing impairment in the risk assessment, NIOSH has found an 8% excess risk of developing occupational noise-induced hearing loss (NIHL) during a 40-year lifetime exposure at the 85-dBA REL. NIOSH has also found that scientific evidence supports the use of a 3-dB exchange rate for the calculation of TWA exposures to noise. The recommendations in this document go beyond attempts to conserve hearing by focusing on prevention of occupational NIHL. For workers whose noise exposures equal or exceed 85 dBA, NIOSH recommends a hearing loss prevention program (HLPP) that includes exposure assessment, engineering and administrative controls, proper use of hearing protectors, audiometric evaluation, education and motivation, recordkeeping, and program audits and evaluations. Audiometric evaluation is an important component of an HLPP. To provide early identification of workers with increasing hearing loss, NIOSH has revised the criterion for significant threshold shift to an increase of 15 dB in the hearing threshold level (HTL) at 500, 1000, 2000, 3000, 4000, or 6000 Hz in either ear, as determined by two consecutive tests. To permit timely intervention and prevent further hearing losses in workers whose HTLs have increased because of occupational noise exposure, NIOSH no longer recommends age correction on individual audiograms.

Download or read book Ion Channels in Health and Sickness written by Fatima Shad Kaneez and published by BoD – Books on Demand. This book was released on 2018-10-10 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion channels are proteins that make pores in the membranes of excitable cells present both in the brain and the body. These cells are not only responsible for converting chemical and mechanical stimuli into the electrical signals but are also liable for monitoring vital functions. All our activities, from the blinking of our eyes to the beating of our heart and all our senses from smell to sight, touch, taste and hearing are regulated by the ion channels. This book will take us on an expedition describing the role of ion channels in congenital and acquired diseases and the challenges and limitations scientist are facing in the development of drugs targeting these membrane proteins.

Download or read book The Mammalian Auditory Pathway Neuroanatomy written by Douglas B Webster and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Springer Handbook of Auditory Research presents a series of com prehensive and synthetic reviews of the fundamental topics in modem auditory research. It is aimed at all individuals with interests in hearing research including advanced graduate students, postdoctoral researchers, and clinical investigators. The volumes will introduce new investigators to important aspects of hearing science and will help established inves tigators to better understand the fundamental theories and data in fields of hearing that they may not normally follow closely. Each volume is intended to present a particular topic comprehensively, and each chapter will serve as a synthetic overview and guide to the literature. As such, the chapters present neither exhaustive data reviews nor original research that has not yet appeared in peer-reviewed journals. The series focusses on topics that have developed a solid data and con ceptual foundation rather than on those for which a literature is only beginning to develop. New research areas will be covered on a timely basis in the series as they begin to mature.
