Bronchiolitis obliterans results in worsening shortness of breath, wheezing, and a dry cough.The symptoms can start gradually, or severe symptoms can occur suddenly. [9] [10] These symptoms represent an obstructive pattern that is non-reversible with bronchodilator therapy, and need to be related to various lung insults. [11]
Cryptogenic organizing pneumonia (COP), formerly known as bronchiolitis obliterans organizing pneumonia (BOOP), is an inflammation of the bronchioles (bronchiolitis) and surrounding tissue in the lungs. [2] [3] It is a form of idiopathic interstitial pneumonia. [4]
Swyer–James syndrome is a manifestation of postinfectious obliterative bronchiolitis. [2] In SJS, the involved lung or portion of the lung does not grow normally and is slightly smaller than the opposite lung. [3]
DPB is classified as a form of "primary bronchiolitis", which means that the underlying cause of bronchiolitis is originating from or is confined to the bronchioles. [ 2 ] [ 3 ] Along with DPB, additional forms of primary bronchiolitis include bronchiolitis obliterans , follicular bronchiolitis, respiratory bronchiolitis , mineral dust airway ...
About 10% to 30% of children under the age of two years are affected by bronchiolitis at some point in time. [ 1 ] [ 2 ] It commonly occurs in the winter season in the Northern Hemisphere . [ 1 ] It is the leading cause of hospitalizations in those less than one year of age in the United States .
Respiratory bronchiolitis is a lung disease associated with tobacco smoking. [1] In pathology, it is defined by the presence of " smoker's macrophages ". [ 1 ] When manifesting significant clinical symptoms it is referred to as respiratory bronchiolitis interstitial lung disease (RB-ILD).
Air trapping, also called gas trapping, is an abnormal retention of air in the lungs where it is difficult to exhale completely. [1] It is observed in obstructive lung diseases such as asthma, bronchiolitis obliterans syndrome and chronic obstructive pulmonary diseases such as emphysema and chronic bronchitis.
These include the features of chronic bronchitis such as inflammation of the small airways and mucus production or hypersecretion. [1] Peribronchial inflammation may lead to fibrosis (obliterative bronchiolitis) [1] as well as features of emphysema, including inflammation leading to alveolar destruction resulting in lung hyperinflation and air ...
