introduction: pulmonary involvement is the most common cause of mortality and disability in patients with systemic sclerosis and it significantly affects the quality of life in these patients. therefore, early diagnosis and treatment of pulmonary involvement seems necessary in patients with ssc. in this study, we aimed to assess the health-related quality of life (hrqol) in patients with sclero...
Background: To reduce the mortality and morbidity rates of cystic fibrosis (CF) patients, and to have an effective clinical management, it is important to monitor the progression of the disease. The aim of this study was to evaluate the progression of lung disease in CF patients by means of assessing the correlation of the CT scoring system with clinical status and pulmonary function test at th...
Background: Depending on the lung volume in radiotherapy fields, breast cancer radiotherapy has documented side effects on pulmonary function, which can be determined by pulmonary function tests. Central lung distance (CLD), the distance from the chest wall to the edge of the field at the central axis, is an indicator of lung volume within the radiotherapy fields. In this study, we aim to detec...
more than 45,000 of 100,000 exposed patients are suffering from late effects of sulfur mustard (sm) after almost 20 years post-exposure. respiratory complications of sm exacerbate over time and are the greatest cause of long-term disability in exposed patients. a triad of cough, expectoration and dyspnea has been found to be the main symptoms among patients. even those who had not developed acu...
abstract background: the current practice to measure rv is either by bpg or helium dilution methods which may not be available in all clinics due to their cost. methods: this paper outlines a method for both direct and indirect calculation of rv via pft with acceptable sensitivity (81 %, 60% ), specificity (71 %, 94%) and validity (76%, 78%) for obstructive and restrictive lung disease respecti...
Abstract Background: Pulmonary vascular resistance (PVR) index is an important hemodynamic variable in determining the severity of cardiopulmonary diseases. This study was done to define the relationship of echocardiographic parameters of ventricular function with PVR. Methods: Mean PVR of 40 patients with cardiac disease was compared with the left ventricle diastolic function indices (LVEF...
Introduction: Echocardiography is usually the first modalities of imaging to evaluate the structural and functional disorders of the heart and great vessels, and colored flow and Doppler images are able to perform hemodynamic and bloodstream evaluations. The goal of this study was the investigation of right ventricular function using echocardiography in patients with pulmonary artery hypertensi...
the work exposure conditions such as dust concentration, exposure time, use of respiratory protection devices and smoking status are effective to cause pulmonary function disorder. the objective of this study was prediction of pulmonary disorders in workers exposed to silica dust using artificial neural networks and logistic regression. a sample of 117 out of 150 workers employed in the stone c...
It has been shown by cardiac catheterization that an increased resistance to blood flow through the lungs occurs in four main conditions: (1) congenital heart disease with potential shunt, (2) mitral valve disease or left ventricular failure, (3) chronic lung disease, and (4) primary and thromboembolic pulmonary hypertension. Although the burden of an increased pulmonary vascular resistance fal...
