PURPOSE Peak expiratory flow (PEF) was measured in healthy children aged five to ten years in order to provide baseline values and to determine correlations between PEF and factors such as gender, age and type of school. METHODS After the Ethical Committee of Research in Human of the School of Medicine of ABC - FMABC approval, PEF and height were measured in 1942 children between five and ten...

The present study was carried out to assess the lung functions in oral contraceptive administered women. Lung function tests were carried out with Spirometer (Vitallograph Compact II). A significant increase in vital capacity (VC) was observed in these women as compared to normal control. There was also a significant decrease in forced expiratory volume in 1 sec./vital capacity (FEV1/VC%) and f...

Electronic spirometers offer the prospect of paperless home monitoring, but data quality is not automatically better than from conventional monitoring. The aim of this study was to determine the extent to which the quality and processing of self-recorded spirometric data from patients with asthma complied with international guidelines for spirometry. Data were from 33 subjects with poorly contr...

In a group of 37 heavy snorers with obstructive sleep apnoea (OSA, Group 1) and a group of 23 heavy snorers without OSA (Group 2) cephalometric indices, ENT indices related to upper airway collapsibility, and nocturnal O2 desaturation indices were related to variables from maximal expiratory and inspiratory flow-volume (MEFV and MIFV) curves. The cephalometric indices used were the length and d...

This study aimed to investigate the effects of particulate matter (PM) on pulmonary function in schoolchildren, as well as the relationships of these effects with interleukin-8. Morning peak expiratory flow (PEF) was measured daily in 399 children during April-May 2012, and in 384 of these children during March-May 2013. PEF's association with the daily levels of suspended particulate matter (S...

STUDY OBJECTIVES To clarify the pathophysiologic features of the relation between asthma and obesity, we measured the effects of weight reduction on peak expiratory flow (PEF) variability and airways obstruction, compared to simultaneous changes in lung volumes and ventilatory mechanics in obese patients with stable asthma. METHODS Fourteen obese asthma patients (11 women and 3 men; aged 25 t...

A double blind, parallel group study was carried out to investigate the effect of inhaled budesonide in a moderate (200 micrograms) and a low (100 micrograms) twice daily dosage compared with the effect of placebo in 103 adults with mild symptomatic asthma. Subjects recorded peak expiratory flow (PEF), asthma symptoms, and beta 2 agonist consumption at home for a period of seven weeks (a one we...

Light detection and ranging (LIDAR) can estimate daily volumes of sand dust particles from the East Asian desert to Japan. The objective of this study was to investigate the relationship between sand dust particles and pulmonary function, and respiratory symptoms in adult patients with asthma. One hundred thirty-seven patients were included in the study. From March 2013 to May 2013, the patient...

BACKGROUND The efficacy of dry powder inhalers depends on the patient's inspiratory flow. Drug delivery from the Turbohaler (Turbuhaler in some countries), a multidose powder inhaler, is optimal at flows of > 40 l/min. The aim of this study was to investigate the peak inspiratory flow that can be generated by asthmatic patients through the budesonide Turbohaler (PIFTBH) during maintenance treat...

Methods A 2–3-week run-in period with twice daily (BID) MF100μg, MF-200μg, or MF-400μg was performed before subject (≥12y) randomization to BID: MF/F-100/10μg, MF100μg, F-10μg, or placebo for 26weeks (n=746); MF/F-200/ 10mg, MF-200μg, F-10μg, or placebo for 26weeks (n=781); MF/F-200/10μg, MF/F-400/10μg, or MF-400μg for 12weeks (n=728 ). Assessment of asthma deterioration (ie, 20% decrease in fo...
