BACKGROUND Asthma guidelines suggest that therapy can be reduced once asthma is controlled. Despite these recommendations, asthmatic patients are seldom stepped down in clinical practice, and questions remain about when and how to reduce asthma therapy. The purpose of the present study was to evaluate lung function and asthma control in patients who were stepped down from the highest recommende...

Bambuterol is the first long-acting oral beta 2-agonist with a 24 h effective duration. In order to investigate the possibility of replacing established treatment modalities with bambuterol once daily, we wanted to compare the bronchodilating and tremorogenic effects of bambuterol, 10 mg once daily, and terbutaline, 5 mg controlled-release (CR) tablets twice daily. The study was of a double-bli...

The purpose of this study was to assess the effects of applying transcutaneous electrical stimulation to paralyzed abdominal muscles during pulmonary function testing (PFT) of individuals with spinal cord injury (SCI). Ten male subjects with anatomical level of SCI between C5-T7 were studied. Subjects performed PFTs with and without electrical stimulation delivered to the abdominal muscles. Sub...

The purpose of the present study was to investigate: 1) whether tidal flow patterns can be used to discriminate between children with asthma and those without respiratory illness; and 2) whether reversibility to salbutamol in young children can be detected by tidal breathing analysis? Lung function was measured by tidal flow-volume loops (SensorMedics 2600) in 26 awake young children (13 males)...

Peak expiratory flow (PEF) variability can be considered as an index of bronchial lability. Population studies on PEF variability are few. The purpose of the current paper is to describe the distribution of PEF variability in a random population sample of adults with a wide age range (20-70 yrs), and to assess relationships to age, gender and smoking habits. PEF data were collected in 511 parti...

BACKGROUND A combination of salmeterol and fluticasone propionate (SAL/FP) has been shown to be effective in the treatment of asthma. We compared the efficacy and tolerability of SAL/FP (50/250 μg) with fluticasone propionate (FP) 250 μg administrated twice daily for 2 weeks in treating patients with mild to moderate asthma. METHODS This was a randomized, double-blind study in adult patients ...

BACKGROUND Maintaining and building healthy bones during the lifetime requires a complicated interaction between a number of physiological and lifestyle factors. Our goal of this study was to analyze the association between hand grip strength and the maximum peak expiratory flow with bone mineral density and content in adolescent students. METHODS The research team studied 1427 adolescent stu...

The aim of the present study was to examine the efficacy of low-dose inhaled budesonide (BUD) administered via Turbuhaler once or twice daily on symptoms, lung function and bronchial hyperreactivity in children with mild asthma. One hundred and sixty-three children (mean age 9.9 yrs, 56 females/107 males) with mild asthma (forced expiratory volume in one second (FEV1) 103% of predicted, morning...

Guidelines on the use of inhaled steroids in asthma advocate that the daily dose should be chosen according to the severity of the disease. However, the question of the optimal starting dose remains to be properly addressed, as does the issue of the adjustment in dose required for a given patient. Whether a high initial dose of budesonide (800 microg b.i.d) was more efficacious than a standard ...

Background: Routine lung function testing requires expensive equipment, or requires maximum expiratory effort. The airflow perturbation device (APD) is a light handheld device, allowing for serial measures of respiratory resistance noninvasively and effortlessly. Methods: In a convenience sample of 398 patients undergoing pulmonary function testing, we compared routine spirometric indices (forc...
