BACKGROUND Information is limited regarding adherence to the asthma guidelines in Asia, especially for children. OBJECTIVE The aim of the study was to estimate adherence to the asthma guidelines, and investigate reasons for nonadherence. METHODS We conducted a cross-sectional questionnaire survey on the primary care pediatricians practicing in Incheon, Korea. RESULTS Surveys were returned...

The bronchodilator and cardiac effects produced by aerosols of 0.5% isoprenaline and of 0.25, 0.5, and 1% salbutamol administered in 40% oxygen by intermittent positive-pressure ventilation were compared in 24 asthmatic patients. Isoprenaline and salbutamol in concentrations of 0.5% were equipotent in peak bronchodilator effect; salbutamol was superior in total bronchodilator effect and duratio...

Ten patients with life-threatening attacks of asthma (status asthmatiucus') were treated with salbutamol inhaled by intermittent positive pressure breathing, and their response in terms of rise in peak flow rate was measured. They were then given intravenous salbutamol and any further increment in peak flow was measured. Hydrocortisone treatment was started simultaneously and the responses to s...

INTRODUCTION This study aimed to investigate asthma prevalence and severity in women with and without endometriosis. METHODS Before laparoscopy, asthma prevalence was evaluated in 879 women of reproductive age, undergoing surgery because of benign gynaecological conditions. Diagnosis of bronchial asthma was based on the American Thoracic Society criteria; asthma severity was classified in fou...

INTRODUCTION The aim of this study was to evaluate the relationship between airway hyperresponsiveness (AHR) to mannitol and bronchial inflammation measured as exhaled nitric oxide (FeNO) and to assess whether asthma control correlates with AHR to mannitol and FeNO in atopic asthmatic children. MATERIAL AND METHODS Allergy evaluation, the mannitol challenge test, FeNO levels and the Asthma Co...

Asthma is a clinical condition characterized by intermittent respiratory symptoms, nonspecific airway hyperresponsiveness, and reversible airway obstruction. Although the pathogenesis of asthma is incompletely understood, it is clear that airway inflammation is a paramount feature of the condition. Because inhalation of ozone by normal, healthy subjects causes increased airway responsiveness an...

Respiratory symptoms cannot be relied on to make a diagnosis of asthma and/or airways hyperresponsiveness (AHR) in elite athletes. For this reason, the diagnosis should be confirmed with bronchial provocation tests. Asthma management in elite athletes should follow established treatment guidelines (eg, Global Initiative for Asthma) and should include education, an individually tailored treatmen...

OBJECTIVE To define the bronchodilator response (BDR) cutoff point that best identified asthma to determine the frequency of abnormal spirometry results across severity. STUDY DESIGN Controller naïve children were evaluated with clinical criteria alone to establish a diagnosis of asthma and severity classification, then compared with the BDR, which was calculated as the percent change from th...

Asthma is a syndrome that includes several disease variants. Definition of asthma is a chronic disorder of the lung with variable airway obstruction, wheeze/cough, and an underlying inflammatory process with remodeling. It appears that atopic genes are not necessarily directly related to childhood asthma. Airway epithelial cells express genes that encode proteins directly related to asthma. Mat...

Asthma is an airway disease characterised by chronic inflammation with intermittent or permanent symptoms including wheezing, shortness of breath, chest tightness, and cough, which vary in terms of their occurrence, frequency, and intensity. The most common associated feature in the airways of patients with asthma is airway inflammation. In recent decades, efforts have been made to characterise...
