Dynamic hyperinflation is associated with a poor cardiovascular response to exercise in COPD patients.

Cardiopulmonary Dept, Lung Function Unit, University Hospital (via Rasori 10), Parma (43125), Italy.
Background: Pulmonary hyperinflation has the potential for significant adverse effects on cardiovascular function in COPD. The aim of this study was to investigate the relationship between dynamic hyperinflation and cardiovascular response to maximal exercise in COPD patients.
Methods: We studied 48 patients (16F; age 68 yrs ± 8; BMI 26 ± 4) with COPD.
Effects of exercise training and montelukast in children with mild asthma.

Purpose: Data from the general population suggest that habitual exercise decreases bronchial responsiveness, but the possible role of exercise in asthmatics is undefined. The leukotriene receptor antagonist montelukast decreases bronchial responsiveness and exercise-induced symptoms in asthmatic children. This randomized study in children with mild asthma evaluated the combined effects of aerobic training for 12 wk and montelukast or placebo on bronchial responsiveness (BHR) to methacholine, exercise-induced bronchoconstriction (EIB), inflammatory markers in exhaled breath condensate (EBC), and asthma exacerbations.

Pepper spray is defined as a non-lethal agent used in riot control and personal self-defense. Oleoresin capsicum (OC), derived from the fruit of plants in the Capsicum genus, commonly referred to as hot peppers or chilies, is the active agent used in many of these defense sprays. Although generally assumed to be safe and effective, the consequences of OC cannot be predicted with certainty.

For field studies of asthma, portable hand-held pulmonary function testing devices are required. Other than for peak flow measurements, little has been done to validate their use in children. Fifty children aged 5-15 years having asthma symptoms were examined using an exercise challenge (8 min free running outdoors) and a bronchodilation test (salbutamol inhalation at a dose of 0.

The purpose of this study was to demonstrate that a simple submaximal "step-test" could be used as an exercise challenge to identify elementary school students with suspected but undiagnosed asthma. This article also describes a protocol for exercise testing that can be used in epidemiological evaluations. School age children grades 1-4 with suspected but undiagnosed asthma were identified by a 12-item questionnaire completed by a parent or guardian.
