Prediction equations for estimating lung volumes have been determined for Caucasians, African-Americans, and Mexican-Americans. These separate equations were determined because of differences in thoracic morphology between people of various racial groups, making it impossible to use one prediction formula to accurately estimate lung volumes for all individuals. One hundred ninety-one adolescent...

Background: Limb-girdle muscular dystrophy 2E (LGMD 2E), recently renamed as autosomal recessive limb-girdle dystrophy-4 (LGMDR4), is characterized by the lack of beta-sarcoglycan, normally expressed in skeletal muscles and cardiomyocytes. We hypothesized that progressive respiratory left ventricular (LV) failure LGMDR4 could be associated with age interrelated phenomena disease's natural histo...

A cross-sectional study was carried out on one thousand school children studying in three public schools of Delhi and Haryana between 10 to 17 year age group over the period of one year (2001-02). It aimed in studying under diagnosis of asthma in school children and its related factors. Questionnaires including details of medical, social, environmental factors precipitating asthma were filled b...

introduction: recently a relation between female sex hormones and severity of asthma symptoms has been proposed. as a common endocrine dysfunction, polycystic ovary syndrome (pcos) could significantly influence the level of sex hormones in pcos patients. regarding the possible role of sex hormones in airway physiology, the present study was conducted to survey the effects of pcos on pulmonary f...

introduction:  asthma exacerbation is common in children. treatment with oral corticosteroids (ocs) and inhaled corticosteroids are suggested for asthma exacerbation. it is shown that inhaled corticosteroids has similar outcome in reducing asthma symptoms compared to ocs. but few studies have evaluated the pulmonary function changes in these two treatments. in this study, we evaluated the chang...

BACKGROUND Although pulmonary abnormalities have been recognized in patients with inflammatory bowel diseases (IBD), their prevalence and clinical significance are not known. AIM To study the prevalence and clinical significance of pulmonary abnormalities in patients with IBD. METHODS Ninety-five non-consecutive patients with IBD (12 Crohn's disease, 83 ulcerative colitis; mean age 41.9 [SD...

 Abstract Background: Pulmonary involvement in ulcerative colitis (UC) is thought to be rare. There is not a definite document about the question that "Is the lung a target organ in inflammatory bowel disease?" The aim of the present study is to compare lung function between cases with UC and healthy controls. This study will also be of interest about searching the outbreak of pulmonary functio...

objective: sulfur mustard (sm) is a potent mutagenic agent that targets several organs, particularly lung tissue. changes in morphological structure of the airway system are associated with chronic obstructive pulmonary deficiency following exposure to sm. although numerous studies have demonstrated pathological effects of sm on respiratory organs, unfortunately there is no effective treatment ...

background fumes released form welding activities are capable of initiating several acute and chronic respiratory effects. objectives the aim of the present study was to evaluate respiratory symptoms and spirometry parameters in welders of a steel industry. methods this cross-sectional study was conducted in a steel industry and involved 60 welders and 40 non-welders. a questionnaire was used t...

All pulmonologists, including those recently completing training, should be competent in critically evaluating and interpreting pulmonary function tests (PFTs). In addition, some authorities recommend that respiratory therapists learn to provide preliminary PFT interpretations for the medical directors of PFT labs. The 2005 American Thoracic Society/European Respiratory Society guidelines for ...
