Adolescent idiopathic kyphosis causes not only spinal deformities but also rib cage abnormalities that lead to abnormal residual volume and pulmonary capacity revealed in pulmonary function testing (PFT). The objective of this study was to analyze the impact of a physical activity program on respiratory function in surgical patients with kyphosis. From October 2006 to October 2007, a total of 3...

BACKGROUND The exposure to noxious agwents such as lead my cause lung disorders. OBJECTIVES In the present study, pulmonary function tests and self-reported respiratory symptoms in lead exposure workers were compared with matched control subjects. MATERIALS AND METHODS The frequency of respiratory symptoms were evaluated in a sample of 108 lead exposure workers and 100 control subjects with...

OBJECTIVE This study intended to search for potential correlations between anaemia in patients with severe chronic obstructive pulmonary disease (COPD; GOLD stage III) and pulmonary function at rest, exercise capacity as well as ventilatory efficiency, using pulmonary function test (PFT) and cardiopulmonary exercise testing (CPET). SETTING The study was undertaken at Shanghai Pulmonary Hospit...

IMPORTANCE Maternal smoking during pregnancy adversely affects offspring lung development, with lifelong decreases in pulmonary function and increased asthma risk. In a primate model, vitamin C blocked some of the in-utero effects of nicotine on lung development and offspring pulmonary function. OBJECTIVE To determine if newborns of pregnant smokers randomized to receive daily vitamin C would...

To the Editor: We read with great interest the study by Majid et al describing pulmonary function tests (PFTs) and flow-volume loops in patients with tracheobronchomalacia.1 A central question is whether abnormalities in the PFT results and flow-volume loops are attributable to tracheobronchomalacia or concomitant lungdisease (eg,COPDorasthma). A secondary question that remains unaddressed is w...

BACKGROUND: Total lung capacity (TLC), forced expiratory flow between 25 and 75% (FEF25-75%), peak (PEF), or post-bronchodilator volume response is recommended to detect obstructive abnormalities in the lung. The present study was performed evaluate usefulness of these pulmonary function test (PFT) parameters diagnose disease subjects with a restrictive pattern spirometry. <...

Background: Diabetes mellitus is a leading public health problem with increasing incidence and long term complications such as diabetic nephropathy, diabetic neuropathy, diabetic retinopathy etc. These complications are mainly a consequence of macrovascular and microvascular damages of the target organs.The presence of an extensive microvascular circulation and abundant connective tissue in the...

Pulmonary function testing (PFT) is used extensively by pulmonary specialists to address two common clinical questions: (1) What is the risk of a postoperative pulmonary complication in an individual with lung disease? and (2) Will the patient be able to tolerate lung resection surgery? Today, there are numerous tests available to measure pulmonary function; making judicious use of these tests ...

BACKGROUND AND OBJECTIVES The purpose of this study was to investigate the relationship between chronic atrial fibrillation (AF) and reduced pulmonary function. SUBJECTS AND METHODS Eighty-six chronic AF patients who were enrolled from annual health examination programs were studied using echocardiography and pulmonary function tests (PFT). Echocardiography and PFT matched for age, gender, an...

OBJECTIVE To examine pulmonary function, dyspnea and exercise capacity in adult Saudi sickle cell disease (SCD) patients. METHODS The patients were recruited from the hematology clinic at King Khalid University Hospital in Riyadh from January to December 2005. The study involved 39 patients with stable SCD (20 women and 19 men), with a mean age of 22.7+/-7.1 years, hemoglobin level of 95.5+/-...
