Methods A total of 76 consecutive adolescent idiopathic scoliosis patients who were treated with brace included in this study. 20 of 45 patients who were treated with SpineCor brace, and 13 of 31 patients who were treated with rigid brace, were able to finish pulmonary function test (PFT). PFT is administered to 33 patients before and immediately after wearing the brace. TLC, RV, RV/TLC, FVC, F...

OBJECTIVE To correlate the findings of high resolution computed tomography of the chest based on the Bhalla score with the clinical data and spirometry in children and adolescents with cystic fibrosis, and to study the concordance between two radiologists for the Bhalla score and its categories. METHODS We evaluated the medical records of 23 patients from the outpatient clinic. The items eval...

Background and objective We have explored whether assessing the degree of concavity in the descending limb of the maximum expiratory flow-volume curve enhanced spirometric detection of early small airway disease. Methods We used spirometry records from 890 individuals aged ≥40 years (mean 59 years), recruited for the Burden of Obstructive Lung Disease Australia study. Central and peripheral c...

BACKGROUND Although several reports have shown an adverse cardiovascular and metabolic risk profile associated with childhood obesity, few reports have examined the effects of childhood obesity on pulmonary function. OBJECTIVE The purpose of this study was to examine the influence of obesity on pulmonary function in Navajo and Hopi children. METHODS Subjects included 256 (110 males, 146 fem...

BACKGROUND Despite the presence of many textile and dyeing plants in Iran, we couldn't find similar studies in this country. Forthermore, considering progress in the dyeing process and engineering controls, assessment of respiratory system is important for these workers. The present study was performed to evaluate the respiratory system in dyeing workers. METHODS In a cross-sectional study, 1...

The single breath diffusing capacity of the lung for carbon monoxide (Dsb) was measured using three equations to describe CO uptake separately during inhalation, breath holding, and exhalation in 24 patients with cystic fibrosis and 30 control subjects with similar age and height distributions. Using the control group, we developed two prediction equations for Dsb: one based on height, age, and...

Patients with cystic fibrosis (CF) and advanced pulmonary disease have pulmonary limitation of exercise, often associated with arterial oxygen desaturation. Improving oxygenation during exercise by providing supplemental oxygen may improve exercise performance in these patients. To test this, we performed graded exercise stress tests in 22 CF patients with severe pulmonary disease (mean PaO2, 6...

INTRODUCTION A well-fitting wetsuit exerts a pressure on the body that may influence spirometry. This pressure is expected to reduce the forced vital capacity (FVC) due to hampered inspiration. Since the shape of the spirometric flow curve should not be changed by the pressure effects of the wetsuits, FVC, the forced expiratory volume during the first second of expiration (FEV₁), the peak expir...

Obese people have higher risk of respiratory symptoms. The relationship between obesity and lung function varies with age, race, and geographical region. The objective of this study is to examine the effects of body mass index on spirometric tests among adults in Xi'an city.This is a cross-sectional study. Pulmonary function testing was conducted on participants recruited from Xi'an, China betw...

background: there is evidence that pulmonary function abnormalities are present in patients with inflammatory bowel disease (ibd). the aim of this case-control study was to assess the frequency of pulmonary dysfunction in patients with ibd. materials and methods: pulmonary function of 37 patients with ibd (8 with cd and 29 with uc) without any known pulmonary disease was tested by body-box plet...
