Asthma is the most common cause of exercise-induced shortness of breath in children and adolescents. While a diagnosis of asthma is often correct, University of Iowa pediatric pulmonary physicians caution that other unrelated conditions also can cause shortness of breath during exercise.
In cases where the asthma diagnosis is questionable, the UI experts recommend further testing to identify the true cause of exercise-induced shortness of breath. "Asthma usually responds well to treatment, and people with asthma who are well treated can have normal exercise tolerance," said Miles Weinberger, M.D., professor of pediatrics in the UI Roy J. and Lucille A. Carver College of Medicine and director of the Pediatric Allergy and Pulmonary Division at Childrens Hospital of Iowa. "However, if the asthma medication doesnt work and the patient has normal lung function when measured before exercise, it is probably not asthma.
"If a patient is not responding to the simplest measure, such as use of a bronchodilator inhaler, and there are no other asthmatic symptoms, the exercise-induced shortness of breath, also known as dyspnea, requires further detailed evaluation," he added.

Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.
Researchers of the “Micro, Nano and Molecular Systems” Lab at the Max Planck Institute for Intelligent Systems in Stuttgart, together with an international...
