Pathophysiology Of Pain Perception

Under certain pathological conditions, the pain processing system, which includes both physiological and psychological components, can produce the experience of pain in the absence of any peripheral noxious event. Considerable evidence now indicates that alterations in pain perception are characteristic of many clinical pain states. Pathophysiology of Pain Perception primarily examines these pathological alterations in the pain-signaling system, with contributions from leading researchers in the field focusing on the functioning of the pain processing system under normal and pathological conditions. The understanding of pain perception is essential for optimal diagnosis and treatment of acute and chronic pain. This book covers the basics of pain perception (peripheral and central neurotransmission, methods of assessment), various pathological (chronic pain conditions, neurological and psychiatric diseases, cardiovascular disease), and non-pathological alterations of pain perception (pregnancy, labor) as well as the treatments aiming at influencing pain perception such as pharmacological, physical and psychological treatments.

This text covers the fundamentals of pain, the pharmacology of drugs used, and summarises the current evidence base for the management of acute pain. It provides practical direct clinical applications and strategies for the management of specific medical conditions in patient groups such as the elderly

An expert explores the biological and emotional nature of pain: why it hurts and why some pain is good and some pain is bad. If you touch something hot, it hurts. You snatch your hand away from the hot thing immediately. Obviously. But what is really happening, biologically—and emotionally? In Understanding Pain, Fernando Cervero explores the mechanisms and the meaning of pain. When you touch something hot, your brain triggers a reflex action that causes you to withdraw your hand, protecting you from injury. That kind of pain, Cervero explains, is actually good for us; it acts as an alarm that warns us of danger and keeps us away from harm. But, Cervero tells us, not all pain is good for you. There is another kind of pain that is more like a curse: chronic pain that is not related to injury. This is the kind of pain that fills pain clinics and makes life miserable. Cervero describes current research into the mysteries of chronic pain and efforts to develop more effective treatments. Cervero reminds us that pain is the most common reason for people to seek medical attention, but that it remains a biological enigma. It is protective, but not always. Its effects are not only sensory but also emotional. There is no way to measure it objectively, no test that comes back positive for pain; the only way a medical professional can gauge pain is by listening to the patient's description of it. The idea of pain as a test of character or a punishment to be borne is changing; prevention and treatment of pain are increasingly important to researchers, clinicians, and patients. Cervero's account brings us closer to understanding the meaning of pain.

All physicians are involved in the management of pain at some level or the other, but of the various specialties and health professions, orthopedic surgeons are at the frontline of delivering perioperative pain care for a wide variety of problems that range from skeletal trauma, joint replacement procedures, bone tumors and spinal conditions. Perioperative Pain Management for Orthopedic and Spine Surgery offers a concise yet comprehensive overview of the surgical spine pain management field to help practitioners effectively plan and enhance perioperative pain control. Chapters provide guidance on solving common dilemmas facing surgeons who are managing patients with pain related problems and clinical decision-making, and explore essential topics required for the trainee and practitioner to quickly assess the patient with pain, to diagnose pain and painful conditions, determine the feasibility and safety of surgical procedure needed, and arrange for advanced pain management consults and care if needed. This text also explores the latest evolving techniques and appropriate utilization of modern equipment and technology to safely provide care. Highly accessible and written by experts in the field, Perioperative Pain Management for Orthopedic and Spine Surgery is an ideal resource for practicing orthopedic and spine surgeons, anesthesiologists, critical care personnel, residents, medical students.

This volume represents edited material that was presented at a conference on brainstem modulation of spinal nociception held in Beaune, France during July, 1987. Pain Modulation, Volume 77 in the series Progress in Brain Research reviews, analyses and suggests new research strategies on several relevant topics including: the endogenous opioid peptides; sites of action of opiates; the role of biogenic animes and non-opioid peptides in analgesia; dorsal horn circuitry; behavioural factors in the activation of pain modulating networks and clinical studies of nociceptive modulation.

New updated edition first published with Cambridge University Press. This new edition includes 29 chapters on topics as diverse as pathophysiology of atherosclerosis, vascular haemodynamics, haemostasis, thrombophilia and post-amputation pain syndromes.

Painâ€"it is the most common complaint presented to physicians. Yet pain is subjectiveâ€"it cannot be measured directly and is difficult to validate. Evaluating claims based on pain poses major problems for the Social Security Administration (SSA) and other disability insurers. This volume covers the epidemiology and physiology of pain; psychosocial contributions to pain and illness behavior; promising ways of assessing and measuring chronic pain and dysfunction; clinical aspects of prevention, diagnosis, treatment, and rehabilitation; and how the SSA's benefit structure and administrative procedures may affect pain complaints.
