dr.mirsadraei and colleagues performed an interesting study about the lung hrct findings in chemical warfare patients who suffering from long-term pulmonary complications. they found that air trapping and mosaic attenuation were the most common lung hrct findings. also they divided patients in different clinical entities according to the lung hrct findings (bronchiolitis oblitrans, pulmonary fi...

BACKGROUND The perception of symptoms is a cornerstone in asthma management, but studies concerning this aspect provide conflicting evidence. The visual analog scale has been proposed as a useful tool for assessing perception of respiratory symptoms. The present study investigated whether visual analog scale assessment of perception of asthma symptoms was correlated to lung function or clinical...

the aetiology behind odor-related chronic somatic symptoms (o-rcss) is unknown, although both immunological and psychiatric causes have been suggested. the aim of this study was to investigate the occurrence of self-reported asthma and hay fever and psychiatric symptoms in individuals having o-rcss compared to individuals with similar chronic somatic symptoms (css) which were not odors-related,...

Background and Aim. Asthma is common in endurance athletes including swimmers. Our aim was to study gender differences in asthma, allergy, and asthmatic symptoms in swimmers and investigate the effects of varying intensities of physical exercise on competitive swimmers with asthma. Methods. Three hundred highly trained swimmers (156 females and 144 males) were studied by a questionnaire. Their ...

Objective: This study aimed to investigate the prediction of asthma control on the basis of perceived stress, locus of control, and self-efficacy in adult patients with asthma.  Methods: This was a descriptive-correlative and cross-sectional study.The solecty of this study is all asthmatic patients in Tehran. our sample consisted of 100 participants who were selected by purposeful sampl...

RESULTS. A total of 4.8% of children had atopic asthma, 1.9% had nonatopic asthma, 3.4% had resolved asthma, and 4.3% had frequent respiratory symptoms. Mean BMI was higher among children with nonatopic asthma, whereas prenatal maternal smoking was a risk factor for resolved asthma. Atopic and nonatopic asthma were similar for most measures of asthma severity (eg, medication use and lung functi...

BACKGROUND Difficult-to-control asthma has been associated with gastroesophageal acid reflux. Acid-suppressive treatment has been inconsistent in improving asthma control. OBJECTIVE To determine whether a proton-pump inhibitor improves asthma control in adult asthmatic patients with acid reflux symptoms. DESIGN Multicenter, double-blind, randomized, placebo-controlled trial. SETTING Twent...

The objective was to determine if tobacco exposure is associated with year-round asthma symptoms. We analyzed baseline data from a multistate survey of 896 pediatric patients with asthma participating in a randomized controlled trial. Daytime symptoms, nocturnal symptoms, and limitations in activity because of asthma tend to increase during the winter season (p 0.05 for all comparisons, except ...

BACKGROUND The International Study on Asthma and Allergies in Childhood (ISAAC) reported a prevalence of asthma symptoms in 17 centers in nine Latin American countries that was similar to prevalence rates reported in non-tropical countries. It has been proposed that the continuous exposure to infectious diseases in rural populations residing in tropical areas leads to a relatively low prevalenc...
