Background: Group 1 and 3 pulmonary hypertension (PH) develop through different pathological mechanisms but have similar hemodynamic abnormalities. Systemic sclerosis (SSc) is associated with both vascular disease (PVD) interstitial lung (ILD), making it challenging to differentiate group PH in those patients. A previous study using quantitative evaluation of chest computed tomography (CT) demo...

Introduction: Recently a relation between female sex hormones and severity of asthma symptoms has been proposed. As a common endocrine dysfunction, polycystic ovary syndrome (PCOS) could significantly influence the level of sex hormones in PCOS patients. Regarding the possible role of sex hormones in airway physiology, the present study was conducted to survey the effects of PCOS on pulmonary f...

PURPOSE To utilize Gaussian mixture model (GMM) for the quantification of chronic obstructive pulmonary disease (COPD) and to evaluate the combined use of multiple types of quantification. MATERIALS AND METHODS Eighty-seven patients (67 men, 20 women; age, 67.4 ± 11.0 years) who had undergone computed tomography (CT) and pulmonary function test (PFT) were included. The heterogeneity of CT att...

Materials and methods 16 patients (9 girls) with diagnosis of JDM (age 3–16,2 yrs) performed pulmonary function tests (PFT). 14 were receiving treatment; all had muscular testing. 13 had weakness as major symptom. Respiratory symptoms: dry cough in 2/16; reduced exercise tolerance: 3/16. Chest xray: normal in 13/13. Echocardiogram and ECG: normal in all. 9/16 had positive ANA-Ab; antiJO1 Ab neg...

STUDY OBJECTIVE To compare the PercussiveTech HF (PTHF) device (Vortran Medical Technology 1; Sacramento, CA) to standard manual chest physiotherapy (CPT) with respect to acute changes in pulmonary function, sputum production, and pulse oximetry in patients with cystic fibrosis (CF). DESIGN Randomized crossover. SETTING University-affiliated, community-based CF center. PARTICIPANTS Ten cl...

BACKGROUND To estimate the potential cost savings by following the current Global Initiative for Chronic Obstructive Lung Disease (GOLD) guideline recommendations in patients being treated for chronic obstructive pulmonary disease (COPD) with the combination of long-acting β(2)-agonist (LABA), long-acting muscarinic antagonist (LAMA) or inhaled corticosteroids (ICS). METHODS The Geisinger Hea...

Grain storage depot workers suffer from different respiratory problems after getting the exposure to storage grain dust. Which is a mixture of pesticides, fungi, silica, bacteria, spores, storage mites, animal hairs, pollens etc. The present study was undertaken to evaluate the fungal spore concentration in summer and winter season as well as the pulmonary function status of the workers; studie...

The purpose of this study was to assess the effects of applying transcutaneous electrical stimulation to paralyzed abdominal muscles during pulmonary function testing (PFT) of individuals with spinal cord injury (SCI). Ten male subjects with anatomical level of SCI between C5-T7 were studied. Subjects performed PFTs with and without electrical stimulation delivered to the abdominal muscles. Sub...
