Handbook of Iron Overload Disorders

A practical, clinically-oriented handbook of iron overload disorders giving a compact guide to normal iron metabolism, iron-related pathobiology, and the diagnosis and management of heritable and acquired iron overload disorders. Many of these disorders were discovered and characterized only in the last decade, and are unmentioned or inadequately described in most texts. Written by clinicians for clinicians, this handbook summarizes information on diverse iron overload conditions, including their history, signs, symptoms, physical examination findings, genetics, genotype-phenotype correlations, pathophysiology, differential diagnosis and treatment. Most physicians, regardless of specialty, encounter patients with systemic or organ-specific iron overload conditions. This book contains essential information for practising adult and pediatric medical specialists in the fields of hematology, gastroenterology, hepatology, rheumatology, endocrinology, diabetology, neurology, oncology, dermatology and internal medicine. Pathologists, pharmacologists, geneticists, genetic counselors and epidemiologists will also find substantial, up-to-date sections in this handbook that are pertinent to their respective fields of interest. - A substantial and up-to-date yet compact guide, written for clinicians by clinicians - Supplemented with clinical images, pedigrees, photomicrographs, illustrative cartoons, tables, and literature references - Detail provides all necessary information to enable accurate assessment, quick diagnosis and effective treatment Contents Foreword; Preface; 1.
