STUDY OBJECTIVES To compare in a clinical setting the within-session reproducibility of two pulmonary function electronic monitoring devices (PiKo-1; Ferraris Respiratory Europe; Hereford, UK; and Spirotel; MIR; Rome, Italy) with one mechanical device (Mini-Wright Peak-Flow Meter; Clement-Clarke International; Harlow, Essex, UK), and to evaluate the accuracy of these devices using as reference ...

Asthma at night is characterized by a nocturnal increase in airway obstruction. It has been hypothesized that nocturnal asthma results from an increase in airway wall inflammation at night. However, studies on inflammatory cells in bronchoalveolar lavage (BAL) fluid and bronchial biopsies have produced conflicting data. This study assessed inflammatory cell numbers at 16:00 h and 04:00 h in bro...

AIM To evaluate the best second-line treatments for patients with uncontrolled moderate asthma. METHODS A single-center, random study was conducted in adult patients with uncontrolled moderate asthma to evaluate the effects of add-on treatments. After add-on treatments for 4 and 12 weeks, the concentration of exhaled nitric oxide (FeNO), average daily durnal peak expiratory flow (PEF) variabi...

The aim of this study was to investigate the possible adverse effects of Asian dust events on respiratory health in asthmatic children. Fifty-two children with mild asthma were studied for eight consecutive weeks in the spring of 2004 (March 8 to May 2). During the study period, five Asian dust days were identified; we included a lag period of two days following each of the events. Subjects rec...

OBJECTIVE To correlate forced expiratory volume in 1 second (VEF(1)) and peak expiratory flow (PEF) with clinical parameters in children with moderate and severe asthma. METHODS This was a non-concurrent cohort study, carried out at a pediatric pneumology clinic, in Belo Horizonte, MG, Brazil, between March and October 2002. The study enrolled children aged 5 to 16 years, with persistent asth...

BACKGROUND The assessment of lung function is of considerable importance in the diagnosis of respiratory diseases, normal reference values need to be determined. The peak expiratory flow (PEF) is a simple, reproducible and easily affordable test of lung function which has been used in resource poor countries like Nigeria. A study PEF was carried out in medical students of the University of Maid...

Individual ability to perceive airway obstruction varies substantially. The factors influencing the perception of asthma are probably numerous and not well established in children. The present study was designed to examine the influence of asthma severity, use of preventive medication, age and gender on the association between respiratory symptoms (RS) and peak expiratory flow (PEF) rates in as...

The aim of this study was to characterize the respiratory function profile of subjects with spinal and bulbar muscular atrophy (SBMA), and to explore the underlying pathological mechanism by comparing the clinical and biochemical indices of this disease with those of amyotrophic lateral sclerosis (ALS). We enrolled male subjects with SBMA (n = 40) and ALS (n = 25) along with 15 healthy control ...

OBJECTIVES To compare the acceptability, reproducibility, and sensitivity of spirometric outcome measures of airway caliber during challenge testing in children. DESIGN FEV(1), forced expiratory volume in 0.75 s, forced expiratory volume in 0.5 s, and peak expiratory flow (PEF) were recorded during stepwise dosimetric histamine challenge tests. The responses were compared, and the reproducibi...

OBJECTIVES To determine the response of nebulized magnesium sulfate on the lung function of acetylcholine-induced asthma children. METHODS Three hundred and thirty children of asthma with positive bronchial provocation test were randomly divided into three groups: magnesium sulfate, albuterol, and a combination of magnesium sulfate and albuterol. Lung function was compared between the three g...
