A sound, medically-based program for managing one's asthma, which, however, tirelessly plugs the National Jewish Center for lmmunology and Respiratory Medicine, where the program originated. Subak-Sharpe (fomerly with the New York Times; author of Overcoming Breast Cancer, 1987, among others) is her usual clear and concise self. She presents the approach to diagnosis, treatment, and rehabilitation of children and adults that was developed at Denver's National Jewish: ""The tens of thousands of patients who have been helped by this program are testament to its soundness. Ask your doctor if these principles can be applied to your treatment program."" She explains normal lung function and what goes wrong to cause asthma (its mechanisms still aren't completely understood); then she looks at ""The Child With Asthma,"" and discusses related factors and issues for children and adults: initiating and exacerbating agents; smoking and asthma; exercise and asthma; job-related asthma, and so on. This is up to date on the medical understanding of the condition, and readers can pick up practical hints for day-to-day management. All in all, a clear, neat explanation of one institution's approach to coping with asthma.
