The National Asthma Education and Prevention Program recently updated its guidelines for the management of asthma. An evidence-based approach was used to examine several key issues regarding appropriate medical therapy for patients with asthma. The updated guidelines have clarified these issues and should alter the way physicians prescribe asthma medications. ⋯ The addition of a long-acting beta2 agonist to an inhaled corticosteroid is superior to all other combinations as well as to higher dosages of inhaled corticosteroids alone. Combination therapy with an inhaled corticosteroid and a long-acting beta2 agonist is the preferred treatment for adults and children with moderate to severe asthma. Antibiotic therapy offers no additional benefit in patients with asthma exacerbations.

Scaphoid fracture is a common injury encountered in family medicine. To avoid missing this diagnosis, a high index of suspicion and a thorough history and physical examination are necessary, because early imaging often is unrevealing. Anatomic snuffbox tenderness is a highly sensitive test for scaphoid fracture, whereas scaphoid compression pain and tenderness of the scaphoid tubercle tend to be more specific. ⋯ Nondisplaced distal fractures generally heal well with a well-molded short arm cast. Although inclusion of the thumb is the standard of care, it may not be necessary. Nondisplaced proximal, medial, and displaced fractures warrant referral to an orthopedic subspecialist.
