Clinicians undergoing competency testing, certification, and periodic recertification are frequently faced with computer-based exams designed to evaluate clinical acumen and judgment. Test questions often include an image or radiograph followed by a vignette of the clinical encounter and a series of questions. Designed to better prepare practitioners for image-intense, computer-based examinations in their respective fields, Atlas of Human Poisoning and Envenoming is a visual and written reminder of the ubiquitous sources of toxins and toxoids in the environment and the outcomes of accidental or intentional toxic exposures in humans. The Second Edition has been restructured with bulleted text, tables, and figures resembling the vignettes that accompany national examinations. Combining the four specialties of toxicology—analytical, medical, environmental, and industrial—into one comprehensive atlas, the book presents photographs and diagrams of toxic plants and animals, their mechanisms of poisoning or envenoming, and the human responses caused by toxic exposure. Highlights of the new edition include: Prescription and illicit drug abuse epidemics Environmental and occupational nephrotoxicology and neurotoxicology Tick paralysis Petrochemical toxicants Biological, chemical, and radiological warfare agents Workplace substance abuse screening and monitoring Epidemiological design and statistical analysis of toxicological investigations The book is conveniently divided into four sections covering general medical toxicology, environmental toxicology, industrial and occupational toxicology, and epidemiology and statistics for toxicology. Supplemented with a 16-page color insert, the second edition includes new images and tables. The atlas will be a useful study guide for a range of practitioners preparing for a lifetime of image-intense national examinations.
