In medical practice there are often complex cases that make extraordinary demands on a clinician’s knowledge and ingenuity. In Challenging Cases in Allergy and Immunology, the authors provide these types of fascinating, and informative cases to complement a basic knowledge of diagnosis and management in these fields. As such, this novel title will be of interest to a wide array of allergists and clinical immunologists, as well as all students of medicine and allied health. Written by a multidisciplinary group of national and international experts, the book covers in detail two or more challenging, real-life cases in each disorder discussed. Each case is followed by a work-up, treatment plan, and discussion that includes a differential diagnosis, up-to-date references, and up to ten thought-provoking, multiple-choice questions that enhance the book’s value as a comprehensive reference and teaching text. The cases include not only the common allergic diseases such as allergic rhinitis, asthma, and food allergy, but also disorders in immune regulation, autoimmunity, and immunodeficiencies. There are chapters on subjects as wide-ranging as anaphylaxis, occupational asthma, and immune-mediated rheumatic diseases. State-of-the-art and evidence-based, Challenging Cases in Allergy and Immunology is an important resource for all clinicians searching for ways to improve their ability to diagnose and manage patients with allergic and immunologic problems.
