Download or read book Tympanic Membrane Perforation and Hearing Loss From Blast Overpressure in Operation Enduring Freedom and Operation Iraqi Freedom Wounded written by and published by . This book was released on 2007 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Primary blast injury is tissue destruction caused by the blast wave of high-pressure air that travels outward from an explosion. Tympanic membrane (TM) rupture is the most common form of primary blast injury. Since the ear is, by design, the body's most sensitive pressure transducer, it is the organ most commonly affected by the dramatic changes in ambient air pressure that occur close to an explosion. Studies of service members injured in combat have demonstrated that TM perforation occurs in approximately 9% of patients wounded by explosives. (Ritenour AE, Blackbourne LH, Kelly JF, et al. Primary blast injury in OEF/OIF: 2003 2006. Unpublished data.) TM rupture occurs more frequently when an explosion takes place in a closed space and when victims are in close proximity to the detonation center. The lowest pressure necessary to perforate a TM is about 5 psi; approximately 50% of TMs will rupture at 15 psi. Various factors have proven to positively or negatively affect an individual's susceptibility to TM rupture. Studies have demonstrated that disease or previous injury, increased age, inadequate pneumatization, and TM position perpendicular to the incident wave all increase the likelihood of perforation. Conversely, plugs of cerumen may exert a protective effect when loose in the external auditory canal, but may serve as a ramrods increasing injury if they are in contact with the TM at the time of the explosion. Simple ear plugs are very effective in reducing the incidence of TM rupture, but are impractical in situations, such as combat, where accurate understanding of quiet verbal communication is critical. Investigators have demonstrated that up to 80% of all perforated TMs heal spontaneously with relatively few requiring operative intervention. Large size of perforation (high grade) and peripheral location of the defect have both been associated with lower rates of spontaneous healing.

Book Synopsis The Relation Between Eardrum Failure and Blast-induced Pressure Variations by : Clayton S. White
Download or read book The Relation Between Eardrum Failure and Blast-induced Pressure Variations written by Clayton S. White and published by . This book was released on 1967 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: In field and laboratory experiments designed to study overall blast effects, incidental observations were made of the ears of over 490 animals. Those inside structures were exposed to a variety of 'atypical' blast waves. Those located inside shock tubes or in the open when high explosives were detonated were exposed to fairly 'typical' wave forms. An attempt was made to relate the incidence of eardrum rupture to various elements of the measured pressure-time curves. The association was not the same for 'typical' and 'atypical' wave forms. Within the limits of the meager differences were noted and discussed with emphasis on the apparent wide variability in tolerance for which an explanation was proposed.
Book Synopsis Animal Models of Neurotrauma by : Mårten Risling
Download or read book Animal Models of Neurotrauma written by Mårten Risling and published by Humana. This book was released on 2019-07-30 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume looks into the need for a variety of experimental models for research on traumatic brain injury (TBI) and peripheral nervous system. It also describes a number of experimental models, such as mechanical devices, that have been developed to model neurotrauma in animal experiments. The overall aim of this book is to explore the variety of models and how they are used in current research. The chapters in this book are organized in four sections and talk about animal models for TBI; animal models for spinal cord or nerve injury; and translational aspects, secondary injuries, in vitro studies, and evaluation of large data sets. In Neuromethods series style, chapters include the kind of detail and key advice from the specialists needed to get successful results in your laboratory. Cutting-edge and comprehensive, Animal Models of Neurotrauma is a valuable resource for researchers interested in expanding their knowledge and research in this developing field.

Book Synopsis Noise and Military Service by : Institute of Medicine
Download or read book Noise and Military Service written by Institute of Medicine and published by National Academies Press. This book was released on 2006-01-20 with total page 339 pages. 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.

Book Synopsis Gulf War and Health by : Institute of Medicine
Download or read book Gulf War and Health written by Institute of Medicine and published by National Academies Press. This book was released on 2009-03-02 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seventh in a series of congressionally mandated reports on Gulf War veterans health, this volume evaluates traumatic brain injury (TBI) and its association with long-term health affects. That many returning veterans have TBI will likely mean long-term challenges for them and their family members. Further, many veterans will have undiagnosed brain injury because not all TBIs have immediately recognized effects or are easily diagnosed with neuroimaging techniques. In an effort to detail the long term consequences of TBI, the committee read and evaluated some 1,900 studies that made up its literature base, and it developed criteria for inclusion of studies to inform its findings. It is clear that brain injury, whether penetrating or closed, has serious consequences. The committee sought to detail those consequences as clearly as possible and to provide a scientific framework to assist veterans as they return home.
