Development of wheezing in patients with cough variant asthma during an increase in airway responsiveness.
Two theories explaining the mechanism for the manifestation of cough without wheeze in patients with cough variant asthma (CVA) are either a higher wheezing threshold or a milder degree of airway hyperresponsiveness. A significant proportion of patients diagnosed as having CVA eventually develop wheezing. The aim of this study was to investigate whether this change in the manifestation of asthm...

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولValidity of Spirometry for Diagnosis of Cough Variant Asthma
Background Cough variant asthma (CVA) is a chronic or recurrent cough without wheezing accompanied by bronchial hyper-responsiveness and eosinophilic inflammation of the airways. This study aimed to evaluate the validity of spirometry in the diagnosis of CVA, as well as determining the specificity and sensitivity of spirometry parameters in CVA. Materials and Methods This descriptive observat...
متن کاملChange in bronchial responsiveness and cough reflex sensitivity in patients with cough variant asthma: effect of inhaled corticosteroids
BACKGROUND Cough variant asthma (CVA) is a cause of chronic cough and a precursor of typical asthma. We retrospectively examined the longitudinal change in bronchial responsiveness and cough reflex sensitivity in CVA patients with respect to the effect of long-term inhaled corticosteroids (ICS). METHODS Provocative concentration of methacholine causing a 20% fall in forced expiratory volume i...
