Effect of a Single Dose Montelukast Sodium on Methacholine Chloride PC20 [PDF]
BACKGROUND: It is currently recommended that leukotriene modifiers (receptor antagonists and synthesis inhibitors) be withheld for a minimum of 24 h before direct bronchoprovocation testing, but there is little evidence to support this recommendation.

Etiologies and Treatment Outcomes of Chronic Cough Diagnosed with a Pathophysiological Diagnostic Procedure: A Single-center Retrospective Observational Cohort Study [PDF]
OBJECTIVE: We developed a pathophysiological diagnostic procedure to identify etiologies of chronic cough (CC) like cough variant asthma (CVA), atopic cough (AC), cough predominant asthma, sinobronchial syndrome (SBS), and mucoid impaction of small ...

Comparison of nasal responsiveness to histamine, methacholine and phentolamine in allergic rhinitis patients and controls [PDF]
In a selected group of rhinitis patients with an IgE‐mediated allergy to house dust mites the nasal response to insufflation of histamine chloride, methacholine and phentolamine was demonstrated to be higher than in a control group. With the methods used

Comparison of arterial storage conditions for delayed arterial ring testing
Objective: Arterial ring testing is the gold standard for measuring arterial function. Increased arterial tone through arterial contraction and impaired endothelial relaxation (endothelial dysfunction) are key metrics of impaired arterial health in ...

Bronchodilator Response in Patients with Persistent Allergic Asthma Could Not Predict Airway Hyperresponsiveness [PDF]
Anticholinergics, or specific antimuscarinic agents, by inhibition of muscarinic receptors cause bronchodilatation, which might correlate with activation of these receptors by the muscarinic agonist methacholine.

Pulmonary Function Tests in Thunderstorm-associated Respiratory Symptoms: A Cross-sectional Study [PDF]
Background: Epidemic thunderstorm asthma is an observed increase in cases of acute bronchospasm following thunderstorms. This study aimed to compare the frequency of obstructive airway disease or bronchial hyperresponsiveness in subjects with ...
