Novel Aspects Of Pthrp Physiopathology

The idea of this book is to attempt to provide an appropriate ground for the discussion of modern PTHrP-related issues, and for the consideration of attentive speculation and comments on current work. It is designed to intersect all the usual lines of disciplines, providing a site for presenting pertinent investigations and for discussing critical questions relevant to the entire field, thus seeking to develop a new focus and new perspectives for all those concerned with PTHrP and its pathobiology.

Hypercalcemia is the most common life-threatening metabolic disorder associated with cancer. The pathophysiological, epidemiological and clinical aspects of hypercalcemia of malignancy are presented in this issue, with a focus on the recently discovered humoral factor responsible for the development of hypercalcemia. With a better understanding of the pathophysiology of this condition and the development of new potent drugs, capable of inhibiting bone resorption, especially bisphosphonates, the clinician will be more successful in correcting hypercalcemia in the great majority of patients.

This comprehensive encyclopedic reference provides rapid access to focused information on topics of cancer research for clinicians, research scientists and advanced students. Given the overwhelming success of the first edition, which appeared in 2001, and fast development in the different fields of cancer research, it has been decided to publish a second fully revised and expanded edition. With an A-Z format of over 7,000 entries, more than 1,000 contributing authors provide a complete reference to cancer. The merging of different basic and clinical scientific disciplines towards the common goal of fighting cancer makes such a comprehensive reference source all the more timely.

Since its discovery, a substantial body of information has been amassed concerning the functions of parathyroid hormone-related protein (PTHrP) in normal and malignant states. This book provides a state-of-the-art discussion of the major aspects of PTHrP biology and pathophysiology, in addition to presenting a historical perspective and discussions on the molecular biology of PTHrP, its mechanism of action, bioassays and radioimmunoassays, and its role in normal physiology. The book will be a primary resource for physicians interested in the clinical aspects of paraneoplastic hypercalcemia and mineral metabolic disorders. It will also serve as a primary resource for basic scientists in skeletal and renal physiology, tumor biology, and hormone action. PROPOSED CONTENTS: INTRODUCTION (A. BROADUS). HISTORY.

Written by world experts, this books follows upon the monumental success of the first edition of The Parathyroids, which was universally acclaimed as the best text on the subject. An authoritative reference that spans the basic science of parathyroid hormone treatment to major clinical disorders in a superb, single compendium, The Parathyroids offers an objective and authoritative view on controversial clinical issues in this rapidly changing field. Every medical school library and virtually every major hospital library will need this book as a reference for students and clinicians. Key Features * Offers objective and authoritative reviews on controversial clinical issues * Written by world experts on parathyroid hormone and its disorders * Superb, state-of-the-art compendium in one convenient volume * Bridges basic science of parathyroid hormone to major clinical disorders * Practical information on clinical management of parathyroid hormone disorders

Metabolic Bone Disease, Third Edition is the new, expanded edition of the classic text, featuring the latest advancements and research information in this fast-moving field. The Third Edition includes the most up-to-date information on molecular mechanisms, basic biology, pathophysiology, and diagnosis and management strategies of metabolic bone disease. Key Features * Edited by "fathers of the field" * An expanded version of a classic AP text * Complete coverage of a fast-growing field

Completely revised and updated, and utilizing the most current evidence and practice guidelines for the treatment of osteoporosis, this comprehensive third edition discusses the basic aspects of bone metabolism, the pathophysiology of osteoporosis, current diagnostic techniques and medical treatment strategies. Osteoporosis is a common disorder that is prevalent in over 20 million Americans over the age of 60. One and a half million osteoporotic fractures occur in the United States every year, including 300,000 hip fractures. Mortality rates after hip fracture approach 25%, with another 50% of patients experiencing a major decrease in their prior level of independence and quality of life. Despite the wide prevalence and severe consequences of osteoporosis, it remains a disorder that is severely under-diagnosed and treated. In this context, specialists and primary care physicians alike are having increasing difficulty keeping up with the rapid changes to the field and incorporating these advances to clinical care. In the years since the last edition of this book was published, the osteoporosis field has changed drastically. In addition to revising and updating existing chapters and removing a few that are no longer as relevant, new chapters discuss an advanced understanding of the cellular and molecular mechanisms underlying the disorder, the introduction of new diagnostic imaging techniques, a more nuanced appreciation of the risks and benefits of osteoporosis therapies, and the introduction of two new classes of osteoporosis medications. Following the format of the second edition, and including helpful key points at the opening of each chapter, this text will present a comprehensive overview of both the basic and clinical concepts relating to each topic, when appropriate. Chapter authors were chosen based on their high level of expertise and leadership in the field. Taken together, this text should thus be of great interest to physicians of multiple specialties, allied health professionals, as well as basic and clinical researchers.
