Environmental Neurotoxicology


Book Description

Scientists agree that exposure to toxic agents in the environment can cause neurological and psychiatric illnesses ranging from headaches and depression to syndromes resembling parkinsonism. It can even result in death at high exposure levels. The emergence of subclinical neurotoxicity-the concept that long-term impairments can escape clinical detection-makes the need for risk assessment even more critical. This volume paves the way toward definitive solutions, presenting the current consensus on risk assessment and environmental toxicants and offering specific recommendations. The book covers: The biologic basis of neurotoxicity. Progress in the application of biologic markers. Reviews of a wide range of in vitro and in vivo testing techniques. The use of surveillance and epidemiology to identify neurotoxic hazards that escape premarket screening. Research needs. This volume will be an important resource for policymakers, health specialists, researchers, and students.




Behavioral Measures of Neurotoxicity


Book Description

Exposure to toxic chemicalsâ€"in the workplace and at homeâ€"is increasing every day. Human behavior can be affected by such exposure and can give important clues that a person or population is in danger. If we can understand the mechanisms of these changes, we can develop better ways of testing for toxic chemical exposure and, most important, better prevention programs. This volume explores the emerging field of neurobehavioral toxicology and the potential of behavior studies as a noninvasive and economical means for risk assessment and monitoring. Pioneers in this field explore its promise for detecting environmental toxins, protecting us from exposure, and treating those who are exposed.

Drinking Water and Health,


Book Description

The most recent volume in the Drinking Water and Health series contains the results of a two-part study on the toxicity of drinking water contaminants. The first part examines current practices in risk assessment, identifies new noncancerous toxic responses to chemicals found in drinking water, and discusses the use of pharmacokinetic data to estimate the delivered dose and response. The second part of the book provides risk assessments for 14 specific compounds, 9 presented here for the first time.




War Neurology


Book Description

Interest in the history of neurological science has increased significantly during the last decade, but the significance of war has been overlooked in related research. In contrast, this book highlights war as a factor of progress in neurological science. Light is shed on this little-known topic through accounts given by neurologists in war, experiences of soldiers suffering from neurological diseases, and chapters dedicated to neurology in total and contemporary war. Written by experts, the contributions in this book focus on the Napoleonic Wars, the American Civil War, the Franco-Prussian War of 1870, World Wars I and II, and recent conflicts such as Vietnam or Afghanistan. Comprehensive yet concise and accessible, this book serves as a fascinating read for neurologists, neurosurgeons, psychiatrists, historians, and anyone else interested in the history of neurology.




Clostridial Neurotoxins


Book Description

Tetanus has been known from the very beginning of medical literature since it was first described by Hyppocrates of Cos in the fifth century B.C. For 24 centuries it was considered a neuro logical disease until the breakthrough of CARLE and RATIONE (1884) who demonstrated its infectious etiology. Following the establishment of purified cultures of Clostridium tetani(KITASATO 1889), FABER (1890), and TIZZONI and CATIANI (1890) demon strated that the disease is actually an intoxication caused by a proteic neurotoxin. This toxin was shown by BRUSHCHETIINI (1892) to move retroaxonally and to act at the spinal cord level. Soon thereafter VAN ERMENGEN (1897) demonstrated that botu lism is also due to intoxication with a protein toxin produced by bacteria of the genus Clostridium. These bacteria and their spores and ubiquitous, and the majority of them do not produce neurotoxins. The selective advantage of producing such potent toxin is still a matter of speculation (see Popoff, this volume). The next major advance was the discovery that tetanus neurotoxin 1 can be converted by formaldehyde treatment to a nonpathogenic but still fully immunogenic form, and that this can be used successfully as a vaccine to prevent tetanus (RAMON and DESCOMBEY 1925). Similar vaccines (toxoids) can be prepared with botulism neurotoxins (see MiDDLEBROOK and BROWN, this volume). The prevention oftetanus by vaccination (see Galatzka and Gasse, this volume) is one of the great successes of basic research coupled with an efficient public medicine service.

Pediatric Neurotoxicology


Book Description

This book focuses on children and the impact of neurotoxins on the developing brain to guide the practice of psychologists working with children in clinical and school settings. Each chapter covers a distinct neurotoxin or group of neurotoxins, with particular emphasis on the impact of the neurotoxin exposure on the developing brain and long-term cognitive and psychosocial outcomes. This is more complex than studying neurotoxins with adults because of the rapid development occurring in the child's brain. Further, children are more susceptible than adults to the effects of neurotoxins due to their developmental status. Many of the effects discussed in this volume occur in utero, thus setting the stage for an altered developmental trajectory.
