Randomized Controlled Trial Multicenter Study Clinical Trial
Emergency treatment of acute asthma with albuterol metered-dose inhaler plus holding chamber: how often should treatments be administered?
To determine the optimal treatment interval for administering albuterol metered-dose inhaler (MDI) with a holding chamber to patients presenting to the emergency department (ED) with acute asthma. ⋯ For acute asthma, albuterol MDI with a holding chamber can be given optimally at 60-min intervals with minimal adverse effects for the majority of patients. However, patients who initially demonstrate a low or poor bronchodilator response to albuterol should be given subsequent treatments at 30-min intervals. This will optimize care and conserve resources for patients who will benefit the most.

Multicenter Study Comparative Study
Likelihood of malignancy in a solitary pulmonary nodule: comparison of Bayesian analysis and results of FDG-PET scan.
To compare the probability of cancer in a solitary pulmonary nodule using standard criteria with Bayesian analysis and result of 2-[F-18] fluoro-2-deoxy-D-glucose-positron emission tomographic (FDG-PET) scan. ⋯ FDG-PET scan as a single test was a better predictor of malignancy in solitary pulmonary nodules than the standard criteria using Bayesian analysis. FDG-PET scan can be a useful adjunct test in the evaluation of solitary pulmonary nodules.
