Cystic fibrosis (also known as CF or mucoviscidosis) is an autosomal recessive genetic disorder affecting most critically the lungs, and also the pancreas, liver, and intestine.
Figure B shows fibrosis (scarring) in the lungs. The inset image shows a detailed view of the fibrosis and how it damages the airways and air sacs. [1] Specialty: Pulmonology: Symptoms: Shortness of breath, dry coughing [1] Complications: Pulmonary hypertension, heart failure, pneumonia, pulmonary embolism [1] Usual onset: Gradual [1] Causes ...
Bronchiectasis may result from a number of infectious and acquired causes, including measles, [11] pneumonia, tuberculosis, immune system problems, as well as the genetic disorder cystic fibrosis. [12] [3] [13] Cystic fibrosis eventually results in severe bronchiectasis in nearly all cases. [14] The cause in 10–50% of those without cystic ...

The pulmonary alveolar macrophage is a key cellular element in the initiation and perpetuation of lung injury and fibrosis. Many particles activate the inflammasome and induce IL-1 production. The more reactive particles trigger the macrophages to release a number of products that mediate an inflammatory response and initiate fibroblast ...
Research by sports scientist John Dickinson found that 70 percent of UK-based members of the British swimming team had some form of asthma, as did a third of Team Sky cyclists, compared to a national asthma rate of eight to ten percent, [24] whilst a study by the United States Olympic Committee in 2000 found that half of cross-country skiers ...
