Available in PDF, EPUB and Kindle. Book excerpt: Common forms of preventable hearing loss are drug and noise-induced hearing loss which are believed to be produced by a similar mechanism. The generation of reactive oxygen species appears to be a common mechanism mediating hearing loss produced by these different sources. As such, a number of laboratories have focused their research towards identifying the sources of ROS production in the cochlea following administration of chemotherapeutic agents or noise exposure. This led to the identification of ROS generating enzymes, such as xanthine oxidases, nitric oxide synthase, and NADPH oxidases which are activated and/or induced during the development of hearing loss. A consequence of these findings was the implementation of antioxidants in preclinical studies for the treatment of hearing loss. These antioxidants have provided different levels of protection in animal and human studies, but none of these have been approved by the US Food and Drug Administration for the treatment of hearing loss. More recently, it was shown that noise-induced hearing loss was associated with recruitment of inflammatory cells and mediators in the cochlea. This finding would suggest that noise could produce injury to the cochlea which stimulates local and/or circulating inflammatory cells. A similar finding was observed in the cochlea following administration of the anticancer drug, cisplatin. In addition, our laboratory and others have provided a plausible mechanism by which noise or chemotherapeutic agents could stimulate the inflammatory response. Surprisingly, this mechanism involves ROS activation of transcription factors linked to inflammatory processes in the cochlea. These studies have led to the use of anti-inflammatory agents for the treatment of hearing loss. Preliminary studies targeting inflammatory cytokines appear especially promising in preclinical studies. A primary goal of this project is to describe our current understanding of the oxidant hypothesis of noise and drug-induced hearing loss and show how this relates to cochlear inflammation. Several different aspects of the cochlear inflammatory process will be discussed in detail, ranging from the sources of inflammatory cells, chemokines, inflammatory cytokines, and cochlea resident immune cells. Molecular pathways leading to activation of the local inflammatory process will be highlighted and treatment options will be discussed. The relevance of certain clinically used anti-inflammatory interventions, such as trans-typmanic steroids will also be discussed. Furthermore, we will examine recent patents focusing on the use of anti-inflammatory agents for the treatment of drug and noise-induced 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: 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.

Available in PDF, EPUB and Kindle. Book excerpt: In 1900, for every 1,000 babies born in the United States, 100 would die before their first birthday, often due to infectious diseases. Today, vaccines exist for many viral and bacterial diseases. The National Childhood Vaccine Injury Act, passed in 1986, was intended to bolster vaccine research and development through the federal coordination of vaccine initiatives and to provide relief to vaccine manufacturers facing financial burdens. The legislation also intended to address concerns about the safety of vaccines by instituting a compensation program, setting up a passive surveillance system for vaccine adverse events, and by providing information to consumers. A key component of the legislation required the U.S. Department of Health and Human Services to collaborate with the Institute of Medicine to assess concerns about the safety of vaccines and potential adverse events, especially in children. Adverse Effects of Vaccines reviews the epidemiological, clinical, and biological evidence regarding adverse health events associated with specific vaccines covered by the National Vaccine Injury Compensation Program (VICP), including the varicella zoster vaccine, influenza vaccines, the hepatitis B vaccine, and the human papillomavirus vaccine, among others. For each possible adverse event, the report reviews peer-reviewed primary studies, summarizes their findings, and evaluates the epidemiological, clinical, and biological evidence. It finds that while no vaccine is 100 percent safe, very few adverse events are shown to be caused by vaccines. In addition, the evidence shows that vaccines do not cause several conditions. For example, the MMR vaccine is not associated with autism or childhood diabetes. Also, the DTaP vaccine is not associated with diabetes and the influenza vaccine given as a shot does not exacerbate asthma. Adverse Effects of Vaccines will be of special interest to the National Vaccine Program Office, the VICP, the Centers for Disease Control and Prevention, vaccine safety researchers and manufacturers, parents, caregivers, and health professionals in the private and public sectors.

Available in PDF, EPUB and Kindle. Book excerpt: The auditory system is one of the finest structures in the human body. Although its anatomical structure is so small compared to other organs, without it, it would greatly affect a person’s basic life. Hearing loss, also known as hearing impairment, is a partial or total inability to hear. When people communicate with others, listening is always the first step. That is why Helen Keller once said, “Blindness separates people from things; deafness separates people from people.” To avoid the “epidemic” of hearing loss in the near future, it is necessary to promote early screening, change public attitudes toward noise, and wear hearing aids appropriately. Based on the contributions of many authors, whom I sincerely respect, this book incorporates updated developments as well as future perspectives in the ever-expanding field of hearing loss. This book can also serve as a reference for persons who are involved in this field whether they are clinicians, researchers, or patients.

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 acute inflammatory response is the body's first system of alarm signals that are directed toward containment and elimination of microbial invaders. Uncontrolled inflammation has emerged as a pathophysiologic basis for many widely occurring diseases in the general population that were not initially known to be linked to the inflammatory response, including cardiovascular disease, asthma, arthritis, and cancer. To better manage treatment, diagnosis, and prevention of these wide-ranging diseases, multidisciplinary research efforts are underway in both academic and industry settings. This book provides an introduction to the cell types, chemical mediators, and general mechanisms of the host's first response to invasion. World-class experts from institutions around the world have written chapters for this introductory text. The text is presented as an introductory springboard for graduate students, medical scientists, and researchers from other disciplines wishing to gain an appreciation and working knowledge of current cellular and molecular mechanisms fundamental to inflammation.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of the book is to provide a text which brings together the expertise from two separate disciplines applied to a shared problem; that of hearing impairment resulting from an infectious cause. The book has been written to be accessible to both disciplines. It begins with chapters describing the anatomy and function of the ear and its development to allow those unfamiliar with the ear to understand how the pathogen can affect hearing. The following chapters include background information on the relevant viruses, bacteria and other pathogens so that those less familiar with these organisms will be able to understand the context within which they may affect the ear. The book also considers current ways in which these infections may be diagnosed, treated, and the potential for prevention.

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.
