asthma and chronic obstructive pulmonary disease (copd) are highly prevalent chronic diseases in the general population. both are characterized by similar mechanisms: airway inflammation, airway obstruction, and airway hyperresponsiveness. however, the distinction between the two obstructive diseases is not always clear. multiple epidemiological studies demonstrate that in elderly people with o...

forty-five patients with chronic obstructive pulmonary disease were studied to compare the acute effects of ipratropium bromide (60 µg), salbutamol (300 µg) and placebo (3 puffs) on the forced expiratory volume in 1 sec (fev 1) and forced vital capacity (pvc). ipratropium bromide produced a significantly greater improvement than salbutamol in both fev1 and fvc at 15,60 and 180 minutes after dru...

background: chronic obstructive pulmonary diseases (copd) are planned to rank fifth in burden of disease and third with respect to mortality by 2020. carrying out research regarding different aspects of copd is mentioned as important health priorities by academic institutions and governments. the burden of lung disease (bold) initiative was designed a decade ago to develop robust models that ca...

introduction: chronic obstructive pulmonary disease (copd) secondary to sulfur mustard gas poisoning, known as mustard lung, is a major late pulmonary complications in chemical warfare patients. serious comorbidities like dyslipidemia are frequently encountered in copd. the aim of this study was to measure the serum lipid profile and evaluate the relation of lipid parameters with the severity o...

materials and methods weighted logistic regression models were used for the analysis of 1,248 cases and 39,995 controls from the 2005 california health interview survey (chis). results the prevalence of spd was 10% in cases and 4% in controls, respectively. the percentages of past and current smoking were higher in cases than controls (50% vs. 24% and 27% vs. 15%, respectively). after adjusting...

the purpose of this study was to examine the effect of intravenous magnesium sulfate on patients with copd exacerbation requiring hospitalization. in this randomized clinical trial 30 patients with copd exacerbation were studied. patients were randomly assigned to group a (case) who concurrent with standard therapy received 2g magnesium sulfate in normal saline infused in 20 minutes on days one...

background: postoperative cognitive dysfunction (pocd) has been an important complication of cardiac surgery over the years. neurocognitive dysfunction can affect quality of life and lead to social, functional, emotional, and financial problems in the patient’s life. to reduce pocd, we sought to identify the association between cognitive dysfunction and perioperative factors in patients undergo...

background: given the importance of the chronic obstructive pulmonary disease (copd) and role of different factors in self-care behaviors of copd patients, this study was conducted to determine the effect of self-efficacy program on self-care behaviors of copd patients. materials and methods: in this semi-experimental study, 62 copd patients were recruited in which 31 subjects were in control g...

background and purpose: despite the high prevalence of chronic obstructive pulmonary disease, there haven,t been definite curative treatment for the disease and focus of treatment has directed towards pulmonary rehabilitation as an effective non-drug treatments. this study were performed to determine the effect of motivational abdominal breathing device on breathing pattern and dyspnea of chron...

overlap syndrome, which is known as the coexistence of chronic obstructive pulmonary disease (copd) and obstructive sleep apnea (osa), was first defined by flenley. although it can refer to concomitant occurrence of any of the pulmonary diseases and osa, overlap syndrome is commonly considered as the coexistence of osa and copd. this disease has unique adverse health consequences distinct from ...
