Randomized Controlled Trial
Factors associated with completion of a behavioral intervention for caregivers of urban children with asthma.
Rates of preventive follow-up asthma care after an acute emergency department (ED) visit are low among inner-city children. We implemented a novel behavioral asthma intervention, Pediatric Asthma Alert (PAAL) intervention, to improve outpatient follow-up and preventive care for urban children with a recent ED visit for asthma. ⋯ The majority of caregivers of high-risk children with asthma were successfully engaged in this home and PCP-based intervention. Caregivers of older children with asthma and those with high stress may need additional support for program completion. Further, the lack of an asthma action plan may be a marker of preexisting barriers to preventive care.

Comparative Study
Corticosteroid timing and length of stay for children with asthma in the Emergency Department.
The aim of this study was to evaluate the relationship between time of corticosteroid administration to children with asthma exacerbations in the Emergency Department (ED) and length of stay (LOS). We hypothesized administration within 60 minutes would be associated with a 10- minute or greater decrease in mean LOS. ⋯ Administering corticosteroids to pediatric asthma patients in the ED within an hour of triage is associated with a 25-minute mean decrease in LOS. With large numbers of asthma visits, a 25-minute decrease in LOS for each child could have a significant impact on patient throughput in the ED.

Bronchiolitis is a common cause of critical illness in infants. Inhaled β(2)-agonist bronchodilators are frequently used as part of treatment, despite unproven effectiveness. The purpose of this study was to describe the physiologic response to these medications in infants intubated and mechanically ventilated for bronchiolitis. ⋯ In this population of mechanically ventilated infants with bronchiolitis, relatively few had a reduction in pulmonary resistance in response to inhaled albuterol therapy. This response was not associated with improvements in outcomes.

The relationship between exhaled nitric oxide (FeNO) and asthma severity or control is inconsistent. Active smoking lowers FeNO, but the relationship between passive smoking and FeNO is less clear. Children may be exposed to low-level environmental tobacco smoke (ETS) or thirdhand smoke, even if parents avoid smoking in the presence of their children. Our hypothesis was that FeNO is lower in children with asthma exposed to low-level ETS when compared with those who are not exposed. ⋯ Children with asthma on low to medium doses of ICS and recent low-level ETS exposure have lower FeNO levels when compared with non-ETS-exposed subjects. Exposure to low-level ETS or thirdhand smoke may be an important variable to consider when interpreting FeNO as a biomarker for airway inflammation.

Review Meta Analysis
Laser acupuncture for the treatment of asthma in children: a systematic review of randomized controlled trials.
Laser acupuncture has often been recommended as a treatment of asthma. The technique is noninvasive, and seems particularly suitable for children. However, the results from several clinical trials are contradictory. The objective of this review was to assess the effectiveness of laser acupuncture in the treatment of childhood asthma. ⋯ The number of RCTs and their total sample sizes are small; and their methodological quality is low. Therefore, no compelling evidence exists to suggest that laser acupuncture is not an effective treatment for childhood asthma. Further rigorous studies are warranted.
