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.

Available in PDF, EPUB and Kindle. Book excerpt: The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.

Available in PDF, EPUB and Kindle. Book excerpt: Exposure to loud noise continues to be the largest cause of hearing loss in the adult population. The problem of NIHL impacts a number of disciplines. US standards for permissible noise exposure were originally published in 1968 and remain largely unchanged today. Indeed, permissible noise exposure for US personnel is significantly greater than that allowed in numerous other countries, including for example, Canada, China, Brazil, Mexico, and the European Union. However, there have been a number of discoveries and advances that have increased our understanding of the mechanisms of NIHL. These advances have the potential to impact how NIHL can be prevented and how our noise standards can be made more appropriate.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The Institute of Medicine carried out a study mandated by Congress and sponsored by the Department of Veterans Affairs to provide an assessment of several issues related to noise-induced hearing loss and tinnitus associated with service in the Armed Forces since World War II. The resulting book, Noise and Military Service: Implications for Hearing Loss and Tinnitus, presents findings on the presence of hazardous noise in military settings, levels of noise exposure necessary to cause hearing loss or tinnitus, risk factors for noise-induced hearing loss and tinnitus, the timing of the effects of noise exposure on hearing, and the adequacy of military hearing conservation programs and audiometric testing. The book stresses the importance of conducting hearing tests (audiograms) at the beginning and end of military service for all military personnel and recommends several steps aimed at improving the military services' prevention of and surveillance for hearing loss and tinnitus. The book also identifies research needs, emphasizing topics specifically related to military service.

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.

Book excerpt: Hearing Loss: Causes, Prevention, and Treatment covers hearing loss, causes and prevention, treatments, and future directions in the field, also looking at the cognitive problems that can develop. To avoid the “silent epidemic of hearing loss, it is necessary to promote early screening, use hearing protection, and change public attitudes toward noise. Successful treatments of hearing loss deal with restoring hearing sensitivity via hearing aids, including cochlear, brainstem, or midbrain implants. Both the technical aspects and effects on the quality of life of these devices are discussed. The integration of all aspects of hearing, hearing loss, prevention, and treatment make this a perfect one-volume course in audiology at the graduate student level. However, it is also a great reference for established audiologists, ear surgeons, neurologists, and pediatric and geriatric professionals. Presents an in-depth overview of hearing loss, causes and prevention, treatments, and future directions in the field Written for researchers and clinicians, such as auditory neuroscientists, audiologists, neurologists, speech pathologists, pediatricians, and geriatricians Presents the benefits and problems with hearing aids and cochlear implants Includes important quality of life issues

Available in PDF, EPUB and Kindle. Book excerpt: Hearing loss is the most common form of sensory impairment in humans, affecting 360 million persons worldwide. In parallel, tinnitus disorder, the perception of a phantom sound often described as a ringing or buzzing, affects around 10–15% of the general population and interferes with daily life. Hyperacusis, defined as a hypersensitivity to moderate-intensity sounds often co-occurs with tinnitus suggesting a common mechanism of dysfunction for these two perceptual disorders. Whereas some drug candidates are in the process of being developed, nowadays no effective treatment exists to cure hearing loss and tinnitus. The topic of this book was selected with the goal of emphasizing mechanisms that induce hearing loss and tinnitus which lead the selection of promising targets for hearing disorder treatment. Hair cells (HC) are the sensory cells of the inner ear required for both auditory and vestibular functions in all vertebrates. HC are progressively lost during ageing and they are in addition sensitive to physical and acoustic traumas, infectious diseases and chemicals present in commonly used treatments such as anticancer, antimalarial or antibiotics. As adult mammals--including humans--cannot regenerate dead HC, all the possible injury could result in irreversible and permanent hearing loss. It has been shown, however, that a limited capacity to regenerate HC exists in mouse at an early stage of development. The regenerative capacity of HC then appears simply “repressed” in adult mammals, and one could expect it will be possible to re-activate it with an appropriate therapeutic approach which is still to be defined. Immune-mediated inner ear disease has been introduced and accepted as one SNHL pathophysiology; it responds to immunosuppressive therapy and is one of the few reversible forms of bilateral SNHL. Macrophages are always present in the spiral ligament of the lateral wall and are activated in response to various types of stimuli, including noise exposure, ischemia, mitochondrial damage, and surgical stress. Recent studies have also revealed another type of immune cell, called perivascular melanocyte-like macrophages (PVM/Ms), in the stria vascularis. The book will include a review of inflammatory/immune cells in the cochlear lateral wall, the pathways involved in cochlear damage and their potential as therapeutic targets. The final chapter provides an overview of current animal model of tinnitus and hyperacusis. Nowadays no effective treatment exists to cure tinnitus and hyperacusis. One major obstacle to arises from the fact that tinnitus is a subjective phenomenon, the only possible diagnosis relies on self-reports of the subjects. The main constraint of the use of animal models is the subjective character of tinnitus. This chapter describe the advancement in animal models which play an important role in revealing the underlying mechanisms and treatment for tinnitus and hyperacusis.

Available in PDF, EPUB and Kindle. Book excerpt: Genetics of Deafness offers a journey through areas crucial for understanding the causes and effects of hearing loss. It covers such topics as the latest approaches in diagnostics and deafness research and the current status and future promise of gene therapy for hearing restoration. The book begins by bringing attention to how hearing loss affects the individual and society. 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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive volume examines the current state of free radical biology and its impact on otology, laryngology, and head and neck function. The chapters collectively highlight the interrelationship of basic and translational studies in each area, define the challenges to translation, and identify the existing basic issues that demand investigation as well as the opportunities for novel intervention to prevent and treat ENT pathology and impairment. In each chapter, or in some cases pairs of chapters, the author(s) have included or married issues of basic research with translational challenges and research, thus defining the pathway by which new basic insights may lead to interventions to prevent or treat impairment. The final chapter of this book reflects a meeting of all the contributors, culminating in a discussion and “white paper” that identifies the challenges to the field and defines the studies and collaborations that may lead to improved understanding of free radical biology in ENT and, subsequently, new interventions to medically treat ENT pathology.

Available in PDF, EPUB and Kindle. Book excerpt: This is the third edition of the foremost medical reference on hereditary hearing loss. Chapters on epidemiology, embryology, non-syndromic hearing loss, and syndromic forms of hearing loss have all been updated with particular attention to the vast amount of new information on molecular mechanisms, and chapters on clinical and molecular diagnosis and on genetic susceptibility to ototoxic factors have been added. As in previous editions, the syndromes are grouped by system (visual, metabolic, cardiologic, neurologic, musculoskeletal, endocrine, etc.), with each chapter written by a recognized expert in the field. Written for practicing clinicians, this volume is an excellent reference for physicians, audiologists, and other professionals working with individuals with hearing loss and their families, and can also serve as a text for clinical training programs and for researchers in the hearing sciences.
