This study aimed to describe lung function in a cohort of children with cystic fibrosis (CF) who underwent infant pulmonary function tests (IPFTs) and preschool spirometry. Children performed up to four IPFTs (raised volume rapid thoracic compression technique) over 1 yr and five preschool spirometry tests over up to 2 yrs during participation in prospective, multicentre studies of infant and p...

introduction: imatinib, a tyrosine kinase inhibitor which resulted in much improvement in the treatment of chronic myelogenous leukemia (cml), may adversely affect thyroid gland function. to date, assessment of thyroid function during imatinib therapy has limited to retrospective studies. the aim of this study was to evaluate the effects of imatinib on thyroid function in a prospective manner. ...

We used a CT program "density mask" outlining areas with attenuation values less than -910 HU, to indicate areas of emphysema on a chest CT and to provide an overall percentage of lung involvement by emphysema. The "density mask" quantitation of emphysema was previously shown to correlate well with the pathologic assessment of emphysema in patients undergoing lung resection. We compared the CT ...

Guidelines on contraindications for lung function tests have been based on expert opinion from >30 years ago. High-risk contraindications to lung function testing are associated with cardiovascular complications such as myocardial infarct, pulmonary embolism or ascending aortic aneurysm. Slightly less risky but still serious contraindications are predominantly centred on recovery from major tho...
