BACKGROUND The contribution of the metal components of particulate pollutants to acute respiratory effects has not been adequately evaluated. Moreover, little is known about the effects of genetic polymorphisms of xenobiotic metabolism on pulmonary function. OBJECTIVES This study was conducted to assess lung function decrement associated with metal components in particulate pollutants and gen...

By means of a simple questionnaire and measurements of height, weight, and peak expiratory flow rates 3061 children from city and rural populations were studied. Children with asthma or other respiratory diseases had lower peak expiratory flow rates, and younger children living in rural areas had higher rates. In 2828 healthy children the peak expiratory flow rate increased with age, height, an...

PEFR is a simple and reliable way of following patients with bronchial asthma and other obstructive airway diseases. Normal data is available for Caucasian and North Indian children but not for ethnic South Indian children. We, therefore, measured Peak Expiratory Flow Rate (PEFR) in 345 healthy South Indian children aged 4-15 years, using the Wright mini peak flow meter. A nomogram was construc...

INTRODUCTION In diagnosis and treatment of respiratory diseases, the assessment of lung functions is of considerable importance. So, normal reference values for pulmonary function tests of any population need to be assessed. OBJECTIVE An attempt has been made in the present study to measure the peak expiratory flow rate (PEFR) in healthy Nepalese children and young adults. MATERIAL AND METH...

OBJECTIVE: To verify the role of peak expiratory flow, measured through portable meters, as an alternative test to assess pulmonary disease in cystic fibrosis. METHODS: Forty-nine patients aged five to 19 years old in stable health condition and able to perform the peak expiratory flow maneuver were included. In the same visit, Shwachman-Kulczycki score was recorded. Linear regression was used ...
