Practical Forensic Pathology and Toxicology is a companion to the authors’ original book on the subject, Forensic Toxicology: Mechanisms and Pathology. This new volume addresses issues that forensic pathologists face when confronted by the suspected or demonstrated presence of drugs or toxins in their cases. Since such considerations include the need for a basic understanding of the direct physiological effects of potentially toxic agents, the authors highlight various connections and interaction between forensic pathology and toxicology. The book is written for both the practicing pathologist, and those in training, who may already have some knowledge of forensic medicine but are on occasion faced with issues that reach beyond a basic determination of cause and manner of death.Pathologists are expected to provide informed, well‑reasoned opinions explaining how a person died—which includes questions about any drugs, prescription medications, or otherwise that may have caused or contributed to death. As such, this book looks at the direct physiological effects of drugs and toxins, answering questions such as “Why does hypernatremia cause seizures?” or “Why can synthetic cannabinoids cause fatal complications, yet THC does not?” or the very timely “What is the mechanism by which an opiate overdose causes death?” Coverage primarily centers on the pathological derangements and physiological consequences of the actions of drugs and toxins, and the cellular mechanisms by which those pathological consequences arise.Organized using an organ system approach, sections are divided into major target organ systems and sections included for affected organs and tissues. While some drugs affect more than one organ system—and some patients will have multiple drugs present—the book’s categorization and organization take this approach to be readily usable for the reader. Case reports are included with additional patient data to show the effects of specific toxins and poisons both alone and in combination with natural disease. Color figures illustrate all aspects of drug or toxin impact on postmortem casework including the scene of death, the deceased persons, and the organs and tissues affected.Practical Forensic Pathology and Toxicology is an invaluable resource for practicing pathologists, toxicologists, and those training for those fields. It also serves as a useful reference for lawyers, judges, insurance companies, and other medical professionals who need to know, in light of what drugs are present in a particular case, what such compounds do, and how their presence (or absence thereof) is—or is not—related to an individual’s death.

Designed for upper-level undergraduate and graduate-level courses, Forensic Toxicology: Mechanisms and Pathology introduces toxicology concepts from a forensic perspective. The book provides an understanding of the mechanistic basis of the action of drugs and toxins, addressing their physiologic and pathologic consequences on the affected organ system. It is this essential connection of toxicology to physiology and biological systems that provides the basis for the toxicologist to understand the basis of behavioral effects of drugs, and for the forensic pathologist to determine cause of death when drugs may be involved.The book gives an overview of organ system physiology and pathology, and the ways in which toxins and drugs affect those systems. Case histories, photographs of gross pathology, and photomicrographs further illustrate the processes and effects of toxic substances on the body. The book also focuses on technological advances in the field and includes cases that demonstrate real-world consequences of the effects of toxins upon organ systems, such as impairment in a DUI case or the fatal induction of cardiac arrhythmia. A comprehensive introduction to pathology and toxicologic concepts, Forensic Toxicology: Mechanisms and Pathology describes the means for identifying types of toxins as well as the key patterns and impacts of drug and toxin processes within the body.

This book covers human identification, trauma analysis, and forensic biomechanics of the foot, ankle, tibia, and femur as frequently encountered in mass casualty incidents, human decomposition, and human rights abuse investigations.
