Dexamethasone vs Hydrocortisone in Management of Exacerbated Chronic Obstructive Pulmonary Disease Patients: A Randomized Controlled Trial

Background: Different types of corticosteroids with different characteristics, such as hydrocortisone and dexamethasone, have been used in treatment of exacerbated chronic obstructive pulmonary disease but drug of choice unclear. The main goal of present study was to compare the efficacy of hydrocortisone and dexamethasone on clinical symptoms, peak expiratory flow, oxidative stress factors and...

Peak Expiratory Flow Rate in Healthy Children from Tehran

Background: Measuring peak expiratory flow rate has been suggested as an important tool in asthma management by all international guidelines.  Objective: Studies on various populations have shown considerable variations in normal values of peak expiratory flow rate. Since reference standards for Iranian children are not available, the present study was performed to establish these standards. Me...

Normal measurement of peak expiratory Flow rate in the high school children in Babol, north of Iran

Background: Peak Expiratory Flow Rate (PEFR) is recommended as a tool for control of asthma. The purpose of this study was to determine the normal value of PEFR in the healthy high school children in Babol, Iran. Methods: This study was conducted on 470 healthy high school children (285 girls, 185 boys with the age between 14-18 years). For the determination of PEFR we used Mini Wright Peak Flo...

The Interpretation of Dyspnea in the Patient with Asthma

Physicians have noted dyspnea in severely ill asthmatic patients to be associated with fright or panic; in more stable patients dyspnea may reflect characteristics including lung function, personality and behavioral traits. This study evaluates the symptom of dyspnea in 32 asthmatic patients twice: first when acutely ill and again after an initial response to therapy. Spirometry was performed, ...
