Randomized Controlled Trial Comparative Study Clinical TrialConstruct validity and responsiveness of the Child Health Questionnaire in children with acute asthma.
To examine the validity and responsiveness of the Child Health Questionnaire (CHQ-PF28) in the context of acute exacerbation of asthma in children. ⋯ Both the physical and psychosocial subscales of the CHQ-PF28 administered 14 days after an ED visit for acute exacerbation of asthma are correlated with poor short-term functional outcome, but scores are only moderately responsive to acute changes in functional status.

Comparative StudyClinical features of recurrent and insidious chronic bird fancier's lung.
Chronic bird fancier's lung (BFL) can be subgrouped into two types. One subgroup of patients develops interstitial pulmonary fibrosis after recurrent acute episodes (recurrent BFL), and the other subgroup of patients has no history of acute episodes but has slowly progressive chronic respiratory disease (insidious BFL). ⋯ Insidious BFL may be misdiagnosed as idiopathic pulmonary fibrosis if a careful history is not taken and antigen-induced lymphocyte proliferation, careful imaging evaluation, and laboratory-controlled inhalation challenge testing are not conducted. In contrast, the clinical findings of recurrent BFL are consistent with hypersensitivity pneumonitis induced by other antigens.
