Usefulness of bronchial reactivity analysis in the diagnosis of bronchial asthma in patients with bronchial hyperresponsiveness

Bronchial Hyperresponsiveness in Asthma*

Measurement ofnonspecific bronchial hyperresponsiveness remains largely a research tool in asthma, and its usefulness in the assessment and management of asthma is poorly defined. We StUdied the relationship of bronchial hyperresponsiveness to the clinical severity of asthma in 54 asthmatic subjects. In order to find out whether measurement of bronchial hyperresponsiveness could be used to pred...

Pulmonary Artery Agenesis with Bronchial Asthma

Unilateral Pulmonary Artery Agenesis (UPAA) is a rare congenital anomaly during the 4 th  week of gestational age. It is defined as an absence of pulmonary parenchyma and its supporting artery. A 9-year-old girl was admitted to our hospital because of chronic cough. Chest examination showed a decrement in lung sound of right hemi-thorax with expiratory wheeze. Chest radiography (CXR) revealed a...

Human platelet antigen polymorphism in bronchial asthma

Background: Asthma is recognized as a common cause of disability, of great economic cost, and of preventable deaths. In this study we aimed to test our hypothesis to evaluate the relationship between the Human Platelet Antigen-1(HPA-1) polymorphism and bronchial asthma and its severity, which would suggest genetic variances that may be responsible for expression or activation of these receptors...

Detecting asthma and bronchial hyperresponsiveness in children.

The prevalence of asthma in children is increasing worldwide. Although the features of asthma are well documented, defining asthma remains a problem. The clinical definition of asthma does not take into account the concept of airway inflammation. A broader definition that incorporates the inflammatory process, reversibility of airway obstruction, and airway responsiveness needs to be more widel...
