From acute respiratory diseases to chronic lung conditions, pulmonology is a vital area of clinical medicine. Due to a wide array of respiratory diseases, clinical presentation of pulmonary conditions can be complex and oftentimes challenging. In addition to recognizing common characteristics of lung diseases, identifying unusual clinical presentation of pulmonary conditions remains an important educational experience. This concise and easy-to-read title provides that experience in practical context, using a case-based system of learning where a unique case is presented and discussed and questions are provided to challenge the learner and reinforce the transmission of knowledge. Challenging Cases in Pulmonology is not an exhaustive review but rather focuses on common and important problems, with emphasis on evaluation and treatment. The book offers 16 chapters consisting of two or more cases followed by five to ten multiple choice questions. A valuable resource for pulmonologists, allergists, primary care physicians, internal medicine, fellows in allergy and pulmonology, and residents in training, this practical title will also be of interest to nurses, physician assistants, and medical students studying pulmonology. Challenging Cases in Pulmonology complements two previously published case-based titles edited by Dr. Mahmoudi: Challenging Cases in Allergy and Immunology (Humana Press, 2009) and Challenging Cases in Allergic and Immunologic Diseases of the Skin (Springer, 2010).
