Effects on small airway obstruction of long-term treatments with beclomethasone/formoterol hydrofluoroalkane (metered-dose inhaler) versus fluticasone/salmeterol (dry-powder inhaler) in asthma: a preliminary study.

New formulations of extrafine particles of long-acting beta-2 agonists plus inhaled corticosteroids (LABA + ICS) have been shown to reach peripheral regions of the lung. The aim of the study was to assess the effect on small airway obstruction of long-term treatments with two different LABA + ICS formulations in asthma. Ten subjects with moderate persistent asthma were enrolled.

Respiratory function in patients with stable anorexia nervosa.

Background: The impact of undernutrition on lung physiology and respiratory muscle performance is still incompletely investigated. The purpose of this study was to assess the functional consequences of malnutrition on the respiratory system in stable patients with anorexia nervosa (AN).

Methods: Pulmonary function tests, maximal inspiratory pressure (Pimax), maximal expiratory pressure (Pemax), and the parameters of control of breathing were obtained in 27 patients with AN (mean [+/- SD] age, 24 +/- 7 years; BMI, 16 +/- 1 kg/m(2); duration of disease, 6 +/- 6 years) and in a group of matched healthy subjects.
