Rationale: Antibiotic inhalation has become widely accepted as a standard treatment for cystic fibrosis (CF) airway infection. We assessed the prevalence and context of inhaled antibiotic use in the North American CF population. Our working hypothesis was that a shift from acute to chronic use of inhaled antibiotics has coincided with increased prevalence of use among CF patients.

We report on HRQoL in men with localized prostate cancer who selected watchful waiting.
Materials And Methods: HRQoL outcomes were reviewed for 310 men diagnosed with prostate cancer from 1990 to 2001 within Cancer of the Prostate Strategic Urological Research Endeavor who chose watchful waiting.
Objectives: To characterize the rate of decline of forced expiratory volume in 1 second (FEV(1)) in children and adolescents with cystic fibrosis and to identify and compare risk factors associated with FEV(1) decline.
Study Design: The rate of decline in FEV(1)% predicted over 3 to 6 years in 3 different age groups was determined. Risk factors for decline were identified and compared among and within age groups as a function of disease severity with repeated-measures, mixed-model regression.

Objectives: This study was designed to evaluate the impact of introducing a managed vision benefit program on the use and costs of vision services in a managed care setting and also to assess satisfaction with those services after the program was introduced.
Methods: Utilization and costs were compared for two groups of patients. The comparison group (n = 36,168) included all patients enrolled for 18 months before implementation of the managed eye-care plan.
