Cryptogenic organizing pneumonia; Other names: Bronchiolitis obliterans with organizing pneumonia, idiopathic interstitial pneumonia [1]: Micrograph showing a Masson body (off center left/bottom of the image – pale circular and paucicellular), as may be seen in cryptogenic organizing pneumonia.
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]
Vaping-associated pulmonary injury (VAPI), [4] also known as vaping-associated lung injury (VALI) [1] or e-cigarette, or vaping, product use associated lung injury (E/VALI), [2] [a] is an umbrella term, [15] [16] used to describe lung diseases associated with the use of vaping products that can be severe and life-threatening.

In a case where gaseous exchange is impaired, mechanical ventilation and intubation may be necessary and if bronchiolitis obliterans develop within 2 to 6 weeks of nitrogen dioxide exposure, corticosteroid therapy or anticholinergic medications may be required for 6 to 12 months to lower the body overreaction to nitrogen dioxide gas. [20]
Ten to 14 days after acute exposure to some agents (e.g. ammonia, nitrogen oxides, sulfur dioxide, mercury), some patients develop bronchiolitis obliterans progressing to ARDS. Bronchiolitis obliterans with organized pneumonia can ensue when granulation tissue accumulates in the terminal airways and alveolar ducts during the body's reparative ...
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).
Bronchiolitis accounts for 3% of emergency department visits for children under 2 years old. [12] Bronchiolitis is the most frequent lower respiratory tract infection and hospitalization in infants worldwide. [15]
Lower respiratory tract infection (LRTI) is a term often used as a synonym for pneumonia but can also be applied to other types of infection including lung abscess and acute bronchitis.
