BACKGROUND The value of impulse oscillometry (IOS) for bronchial provocation testing is poorly defined. We investigated the positive threshold derived from the parameters and diagnostic power of IOS for asthma with the leukotriene D(4) bronchial provocation test. METHODS We enrolled 62 subjects with asthma and 21 healthy subjects. IOS was employed to perform the leukotriene D(4) bronchial pro...
BACKGROUND Severity of chronic obstructive pulmonary disease (COPD) is based either on symptoms/disability or lung function, which have no discernible correlation. We hypothesised that impulse oscillometry (IOS), a non-effort-dependent measure of central and peripheral airway mechanics, could correlate to dyspnoea in COPD. METHODS We analysed screening data from 57 COPD patients who had spiro...
mean age of 50.7 yrs [7]. The most common histological subtypes are hybrid oncocytic (50%) and chromophobe (34%) renal cell carcinoma, while clear cell, oncocytoma and papillary renal cell cancer are less frequently found [7]. Radiographic screening is recommended, with a typical strategy involving abdominal computed tomography and/or renal ultrasound at the time of diagnosis, followed by inter...
OBJECTIVE To evaluate the outcome of a secondary intervention conducted with infants at risk for asthma. DESIGN Families of wheezing infants were randomized to a 1-year intervention or control group; outcome evaluation occurred from April 1, 2000, through September 30, 2003, when children reached 4 years of age. SETTING Home intervention and clinic evaluation. PARTICIPANTS A total of 149 ...
Implementing an effective inter-organizational system (IOS) requires significant organizational as well as technical changes. These will affect stakeholders with varying degrees of power and with varying degrees of interest in the system – yet promoters depend on them if the project is to succeed. Identifying stakeholders and understanding their attitudes enables promoters to manage implementat...
