Though this fifth edition continues to emphasize the definition, medications, and use of asthma treatment plans, it also focuses on the special needs patient, including the pediatric patient, the pregnant patient, and the patient undergoing surgery, as well as on the perennial issues of exercise and asthma, pulmonary aspergillosis, occupation, recreational drug use, and psychological/social considerations. Highlights for the fifth edition include a liberal use of tables and charts to make the book more practical and user-friendly, updates on the many new pharmaceuticals used to treat asthma, and first-time sections on food sensitivity and the diagnosis of asthma.
