Book Description
The pattern of recovery of the respiratory system from blast injury was investigated in sheep exposed to overpressures in a shock tube. Measurements of the pH and blood gas tensions, determinations of the venous- admixture (Qs/Q) and the alveolararterial oxygen gradient (A-a)O2 were conducted before and at intervals up to 132 days following injury. There was an immediate marked increase in Qs/Q, reduction in PaO2, and a moderate increase in (A-a)O2, with very little change in the pH or PCO2 of the arterial blood. The greatest recovery was evident within 24 hours with further gradual improvement seen 2, 7, 14, and 21 days after exposure. After the 21st day, most of the animals exhibited virtual complete recovery of the functional efficiency of the pulmonary system as tested at rest.

Book Description
Traumatic brain injury (TBI) remains a significant source of death and permanent disability, contributing to nearly one-third of all injury related deaths in the United States and exacting a profound personal and economic toll. Despite the increased resources that have recently been brought to bear to improve our understanding of TBI, the developme

Book Description
With the contribution from more than one hundred CNS neurotrauma experts, this book provides a comprehensive and up-to-date account on the latest developments in the area of neurotrauma including biomarker studies, experimental models, diagnostic methods, and neurotherapeutic intervention strategies in brain injury research. It discusses neurotrauma mechanisms, biomarker discovery, and neurocognitive and neurobehavioral deficits. Also included are medical interventions and recent neurotherapeutics used in the area of brain injury that have been translated to the area of rehabilitation research. In addition, a section is devoted to models of milder CNS injury, including sports injuries.

Book Description
Experience with animals exposed in a variety of above and below ground structures during full-scale field operations at the Nevada Test Site in 1953, 1955 and 1957 were reviewed. The data were assembled and summarized to illustrate the nature of the blast-induced problems of significance in protective shelters, "open" as well as "closed". Potential hazards were related to the following: various patterns of variation in environmental pressure; translational events associated with transient, high-velocity winds, ground shock and gravity involving the impact of energized inanimate objects on the one hand the the consequences of whole-body displacement on the other; non-line-of-site thermal phenomena including hot objects and rapidly moving hot, dust- laden air and debris; and dust, in the respirable size range, sufficiently high in concentration even in "closed" shelters as to warrant design measures to minimize or eliminate the occurrence of small particulates whether arising from wall spalling or otherwise. Tentative biological criteria, conceived to help assess human hazards from blast-related phenomena, were presented. Relevant data from the literature and on- going research in environmental medicine were set forth to aid the reader in appreciating how the criteria were formulated, what information was extrapolated from animal data, and wherein "best estimates" were employed. "State-of-the-art" concepts were noted to emphasize areas in which more thinking and research must continue if more refined, complete and adequate criteria are to be forthcoming for assessing man's response to blast-induced variation in his immediate environment.

Book Description
The men and women who served in the Gulf War theater were potentially exposed to a wide range of biological and chemical agents. Gulf War and Health: Volume 1 assesses the scientific literature concerning the association between these agents and the adverse health effects currently experienced by a large number of veterans.

Book Description
This concise, evidence-based board review book, organized according to the ABA keyword list, covers all the fundamental concepts needed to pass written and re-certification board examinations. Each chapter begins with a case scenario or clinical problem from everyday practice, followed by concise discussion and clinical review questions and answers. Discussion progresses logically from preoperative assessment and intraoperative management to postoperative pain management, enhancing the reader's knowledge and honing diagnostic and clinical management skills. New guidelines and recently developed standards of care are also covered. Serving as a companion to the popular textbook Essential Clinical Anesthesia, this resourceful work reflects the clinical experiences of anesthesia experts at Harvard Medical School as well as individually known national experts in the field of anesthesiology. This practical review is an invaluable resource for anesthesiologists in training and practice, whether studying for board exams or as part of continuing education and ABA recertification.

Book Description
Windows to the Brain is the only book to synthesize neuroanatomical and imaging research as it pertains to selected neuropsychiatric diseases, containing all of the "Windows to the Brain" papers published from 1999-2006 in the Journal of Neuropsychiatry and Clinical Neurosciences. These reader-friendly summaries by more than sixty contributors present modern imaging techniques that assist in the diagnosis of neuropsychiatric illness, enhanced by easily understood color graphics of the neuroanatomical circuits of behavior, memory, and emotion. They provide a basic understanding of how to apply a variety of imaging techniques to the study of adult neuropsychiatric disease and how to use neuroimaging to assist in diagnostic work-ups for conditions ranging from sleep disorders to epilepsy to borderline personality. Integrated, color-coded graphics present functional anatomical information in a manner that promotes understanding and use in clinical practice, while the text encompasses a wide range of diseases and injuries across the adult lifespan. The book is organized into four sections that will help readers increase their appreciation of the wide range of research and clinical applications for imaging in neuropsychiatry: chapters on imaging techniques discuss underlying principles, strengths and weaknesses, and applications; chapters on specific diseases demonstrate a range of investigative techniques; anatomy/circuit chapters focus on particular brain structures or functional neuropsychiatric circuits; and final chapters present image-based approaches to understanding or selecting treatment options. Some of the applications described are: Use of fMRI in posttraumatic stress disorder to reveal the delicate balance between the structures of the emotion and memory tracks; Use of high-resolution MRI and nuclear imaging to distinguish between panic disorder and simple partial seizure disorder; Use of functional imaging studies to detect corticobasal degeneration, as a means of better understanding dementia; Use of newer imaging techniques in identifying progressive multifocal leukoencephalopathy, to enable more rapid and reliable tailoring of individual therapy for HIV; Use of functional neuroimaging in the study of fear, in order to better understand and treat anxiety-based psychiatric disorders; Use of neuroimaging studies in conversion disorder, showing implications for the disruption of selfhood in dissociative identity disorder and schizophrenia; Use of FDG-PET scans to look for predictors of treatment response in childhood-onset obsessive-compulsive disorder. Windows to the Brain can help bring less-experienced readers up to speed on advanced imaging and anatomical details that pertain to the modern practice of neuropsychiatry. It is must-reading for specialists in neuropsychiatry and cognitive/behavioral neurology, or for general psychiatrists with an interest in neuroimaging.

Book Description
For personnel standing or prone-side-on to the charge when it is detonated at or near the surface, the side-on incident plus dynamic pressures become the effective pressure; however, with orientations end-on in this situation, only the side-on incident pressure appears to be the maximal effective pressure.
