the link between allergic rhinitis and asthma is well known. bronchial hyperreactivity (bhr) may be present in rhinitis. the present study was aimed to compare airway responses in patients  with rhinitis symptoms alone following exercise challenge, and to  determine relationship of two different respiratory function tests. 98 subjects with rhinitis were investigated by spirometry and impulse os...

OBJECTIVE To describe a practical method for family practitioners to stage chronic obstructive pulmonary disease (COPD) by the use of office spirometry. METHODS This is a review of the lessons learned from evaluations of the use of office spirometry in the primary care setting to identify best practices using the most recent published evaluations of office spirometry and the analysis of preli...

  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...

introduction: the coexistence of asthma and chronic rhinosinusitis (crs) is more common than expected given their individual prevalence in the general population and may affect patient’s quality of life. the aim of this study was to evaluate the prevalence of asthma in chronic rhinosinusitis in mashhad, northeast iran.  materials and methods: this study was performed in two university hospital ...

BACKGROUND Controversy exists regarding the best method to interpret pediatric spirometry. There is also controversy regarding the benefit of performing post-bronchodilator spirometry after normal baseline spirometry. This study compares the use of lower limit of normal (LLN) against percent of predicted (PP) in the interpretation of spirometry. We also investigate the occurrence of a substanti...

BACKGROUND Efforts to promote better health of sickle cell anaemia (SCA) patients in low-income countries through the use of cheap and available alternatives are desirable. OBJECTIVE We investigated whether a locally designed incentive spirometry will improve peak expiratory flow rate (PEFR) of teenage SCA patients. METHODS Forty-nine SCA teenagers were randomized into either the SCA spirom...

To assess the value of spirometry for predicting the risk of pneumothorax (PTX) following percutaneous fine needle aspiration (FNA) of thoracic lesions, we examined retrospectively the incidence of PTX in 89 FNA and associated spirometry. Spirometry results were classified as normal, obstructed, or restrictive. Overall, the PTX rate was 20 percent. When the PTX occurrence was analyzed based on ...

BACKGROUND Spirometry is recommended for diagnosis and management of obstructive lung disease. While many patients with asthma and COPD are cared for by primary care practices, limited data are available on the use and results associated with spirometry in primary care. OBJECT To assess the technical adequacy, accuracy of interpretation, and impact of office spirometry. DESIGN A before-and-...
