conclusions the fev1/fev6 ratio can be used as a valid surrogate for fev1/fvc in the diagnosis of airway obstruction, especially for screening purposes in high-risk populations for copd. moreover, fev6 is an acceptable alternative for fvc in detection of restrictive pattern. results this study shows that the current cut-off points used to detect obstruction and restriction can be replaced by fe...

garbage collectors are occupationally exposed to a variety of airborne contaminants. the main objective of this study was to evaluate the respiratory health of garbage collectors. this study was carried out in fars province, south of iran. a group of 105 garbage collectors and 93 referent subjects were investigated. a standard questionnaire was administered to both groups. furthermore, subjects...

background: several studies have showed an increased prevalence of airflow obstruction in first degree relatives of individuals with chronic obstructive pulmonary disease (copd). considering no specific research had evaluated airway resistance in offspring of patients with severe copd, we utilized a spirometry and a impulse oscillometry (io) to evaluate this population. materials and methods: i...

introduction: metabolic syndrome (mets) and impaired lung functions have been associated with an increased risk for coronary heart disease. the aim of this study was to investigate the pulmonary functions in patients with mets. methods: this cross-sectional study included 200 subjects with mets in the study group and 100 subjects without mets in the control group. participants were examined at ...

introduction: renal failure affects the mechanical and the ventilatory function of the lungs. a few studies have evaluated the ventilatory and pulmonary function in dialysis patients. the present study aimed to compare pulmonary function test (pft) results in patients undergoing hemodialysis (hd) and peritoneal dialysis (pd). materials and methods: we conducted a cross-sectional study on 50  pa...

background: the rapidity of progression of amyotrophic lateral sclerosis (als) to death or respiratory failure impacts patients, clinicians, and clinical investigators. the aim of this study is to evaluate of the pulmonary function tests (pfts) in patients with als and the association between these pfts and survival methods: a total of 36 als patients who pfts, including vital capacity (vc), ma...

Background Calprotectin is a cytosolic protein that belongs to the S-100 protein group with immunomodulatory and antiproliferative actions. The level of this protein increases in infection, inflammation, and malignancy. The aim of this study was to evaluate the level of...

introduction: ultrasonography is currently being used as one of the diagnostic modalities in various medical emergencies for screening of trauma patients. the diagnostic value of this modality in detection of traumatic chest injuries has been evaluated by several studies but its diagnostic accuracy in diagnosis of pulmonary contusion is a matter of discussion. therefore, the present study aimed...

conclusions this study highlights the close link between the role of the phrenic nerve and pulmonary function, such that the use of this nerve as a transfer donor leads to spirometric impairments. results all patients regained biceps power to m3 strength or above. none of our patients experienced pulmonary problems or respiratory complaints, but a significant reduction of spirometric parameters...

introduction: pulmonary involvement secondary to systemic sclerosis (ssc) is the major cause of morbidity and mortality in ssc patients. we designed this study to determine the correlation of important lung function parameters with lung high resolution ct (hrct) scan findings.materials and methods: thirty–two consecutive diffuse ssc patients with pulmonary fibrosis were enrolled in this cross-s...
