asthma usually occurs during childhood but may begin at any age. Most patients with asthma are atopic; however, some patients, particularly those with adult-onset asthma, have no clear allergic basis for their disease. The cardinal features of asthma are reversible airway obstruction, inflammation, and airway hyperresponsiveness. Characteristic    findings    are    wheezing    and    dyspnea;    consider    any    cough    that    is    nocturnal,    seasonal,    or    related    to    a    workplace    or    activity    as    possible    asthma.    Look    for    nasal    polyps    and    aspirin    allergy.
