Translational Pain Research

Basic science and clinical pain research is particularly challenging for several reasons. First, pain is a subjective experience in response to nociception that follows actual or potential tissue damage. Since the ability to respond to this warning signal is essential for our survival, the nociceptive system that produces and transmits nociceptive signals is remarkably redundant and involves diffuse regions of the central nervous system. Second, unlike other sensory modalities, pain is a multi-dimensional experience including at least cognitive, affective, and sensory-discriminative components. Third, pain experiences can be influenced by psychological, socioeconomic, cultural, and genetic predispositions, making it exceedingly complicated to study pain and pain modulation. The topics covered in this volume are carefully selected and directly related to the daily practice of pain medicine. These topics include 1) central mechanisms of pain and pain modulation (Dickenson, Donovan-Rodriguez, Mattews) and clinical use of ion channel blockers (Chen); 2) spinal glutamatergic mechanisms (Guo, Dubner, Ren) and issues related to glutamate receptor antagonists in pain management (Mao); 3) basic science of opioid analgesics (Gintzler, Chakrabarti) and clinical opioid use (Smith, McCleane); 4) inflammatory cytokines (Samad) and clinical use of anti-inflammatory drugs (Fink, Brenner); 5) role of the sympathetic nervous system in pain mechanisms and its relation to clinical pain management (Sharma, Raja); 6) preclinical studies on tricyclic antidepressants (Gerner, Wang) and clinical use of antidepressants in pain management (Greenberg); 7) developing pain pathways and analgesic mechanisms during the developmental stage (Fitzgerald) and challenges of pediatric pain management (Lebel); 8) basic science mechanisms of serotonin agonists and their use in the clinical management of migraine headache (Biondi); 9) clinical research on gender differences in clinical pain and their implications for clinical pain management (Holdcroft); 10) current modalities of clinical cancer pain management (Popescu, Hord); and 11) preclinical and clinical information on alternative medicine (Chen).

One of the Most Rapidly Advancing Fields in Modern Neuroscience The success of molecular biology and the new tools derived from molecular genetics have revolutionized pain research and its translation to therapeutic effectiveness. Bringing together recent advances in modern neuroscience regarding genetic studies in mice and humans and the practicality of clinical trials, Translational Pain Research: From Mouse to Man effectively bridges the gap between basic research and patient care by humanely examining rodent models for pain associated with bone cancer, osteoarthritis, fibromyalgia, and cardiac episodes. Distinguished Team of International Contributors In addition to addressing the groundbreaking technical advances in tract tracing, endocannabinoids, cannabis, gene therapy, siRNA gene studies, and the role of glia, cytokines, P2X receptors and ATP, this book also presents cutting-edge information on: Nociceptor sensitization Muscle nociceptors and metabolite detection Visceral afferents in disease Innovative rodent model for bone cancer pain Highly specific receptor cloning Modular molecular mechanisms relevant to painful neuropathies This sharply focused work also discusses unexpected discoveries derived from brain-imaging studies related to thalamic pain. Translational Pain Research covers the progress made toward bringing laboratory science (much of it at the molecular level) to our understanding of pain phenomena in humans, with the ultimate goal of reducing the suffering that often accompanies pain and its indirect consequences.

Third, pain experiences can be influenced by psychological, socioeconomic, cultural, and genetic predispositions, making it exceedingly complicated to study pain and pain modulation. In this first volume, the current status and new trends of pain research are selectively discussed in order to take a critical and constructive look at the achievements of basic science research that have made significant differences in clinical pain management as well as the gaps between basic science research and clinical pain management.

This book provides a comprehensive review of the latest advances in translational pain and itch research, and presents the cutting-edge developments in the study of our two principal, yet most mysteries sensations. Despite the slow progress in the discovery of effective therapies for chronic pain and pruritus, scientists around the globe now have a better understanding of why and how these conditions occur. Based on these findings, a series of novel treatment strategies are currently under development, and hopefully in a few years, medical practitioners will become more confident and optimistic when facing patients with these annoying and sometimes severe disorders. The contributing authors are world-renowned research scientists, who have made significant discoveries. The book is of interest to neuroscientists, neurologists and pharmacologists

The neurobiology and mechanisms discovered in animals often do not translate to patients with a chronic pain condition. To help researchers and clinicians develop and use models that can help translate data from animals into humans, this book presents experimental animal models, with a focus on how they may translate into humans human experimental pain models, including details about pain induction and assessment human surrogate pain models clinical applications of pain models models that may link mechanisms of pain and pruritus Pain Models contains 29 chapters by internationally recognized experts. It is a comprehensive survey of pain models at different levels, and commentaries by clinicians directly address clinical perspectives. This unique book is unprecedented in its content. It's a quick reminder of the hard work needed to investigate the complex issue of pain perception. With the advent of increasingly sensitive noninvasive investigational tools, the authors want readers to know that basic research is still needed to help develop new drugs. This book will enrich anyone who wishes to know all that goes into conducting pain research with a lab-based pain model.

Chronic pain costs the nation up to $635 billion each year in medical treatment and lost productivity. The 2010 Patient Protection and Affordable Care Act required the Department of Health and Human Services (HHS) to enlist the Institute of Medicine (IOM) in examining pain as a public health problem. In this report, the IOM offers a blueprint for action in transforming prevention, care, education, and research, with the goal of providing relief for people with pain in America. To reach the vast multitude of people with various types of pain, the nation must adopt a population-level prevention and management strategy. The IOM recommends that HHS develop a comprehensive plan with specific goals, actions, and timeframes. Better data are needed to help shape efforts, especially on the groups of people currently underdiagnosed and undertreated, and the IOM encourages federal and state agencies and private organizations to accelerate the collection of data on pain incidence, prevalence, and treatments. Because pain varies from patient to patient, healthcare providers should increasingly aim at tailoring pain care to each person's experience, and self-management of pain should be promoted. In addition, because there are major gaps in knowledge about pain across health care and society alike, the IOM recommends that federal agencies and other stakeholders redesign education programs to bridge these gaps. Pain is a major driver for visits to physicians, a major reason for taking medications, a major cause of disability, and a key factor in quality of life and productivity. Given the burden of pain in human lives, dollars, and social consequences, relieving pain should be a national priority.

The detrimental impacts of pain on the quality of our daily life have drawn increasing attention from researchers, health care providers, policymakers, and social workers. The reality of effective painkillers specifically designed for different types of pain states has been obscured by missing knowledge of the mechanisms of different types of pain. Thus, studying the complexity of pain transduction, which includes various insults to the peripheral nervous systems, sensitized spinal circuits, and altered signals ascending to or descending from the brain, has emerged as a high priority task on the agenda of pharmaceutical companies and other private as well as public agencies. To accomplish this mission, one requires a combination of well-integrated systems, such as a- mal models resembling the pathological conditions of pain transduction, and an understanding of the interactions among pain transducers and mediators at the molecular level. Thanks to rapid advancements in the development of novel cellular and molecular biology techniques, as well as in our understanding of physiology, and of the behavioral pharmacology of pain transduction, the time is now ripe for dissecting the molecular mechanisms of pain transduction using multidisciplinary approaches. Indeed, my acceptance of the invitation from the series editor, Dr. John Walker, to assemble a book of methods and protocols for pain research was inspired by these emerging needs. The purpose of Pain Research: Methods and Protocols is to provide st- by-step methods and protocols of multidisciplinary approaches related to the study of pain transduction.
