While the acronyms are similar, reactive airway disease (RAD) and reactive airways dysfunction syndrome (RADS) are not the same. [1]Reactive airways dysfunction syndrome was first identified by Stuart M. Brooks and colleagues in 1985 as an asthma-like syndrome developing after a single exposure to high levels of an irritating vapor, fume, or smoke.
These lymph nodes form four main groups including paratracheal, tracheobronchial, bronchopulmonary and pulmonary nodes.. Paratracheal nodes are located on either side of the trachea.
The trachea is the largest tube in the respiratory tract and consists of tracheal rings of hyaline cartilage. It branches off into two bronchial tubes, a left and a right main bronchus. The bronchi branch off into smaller sections inside the lungs, called bronchioles. These bronchioles give rise to the air sacs in the lungs called the alveoli. [10]
Bronchitis describes the swelling or inflammation of the [7] bronchial tubes. Additionally, bronchitis is described as either acute or chronic depending on its presentation and is also further described by the causative agent.
MAI is common in immunocompromised individuals, including senior citizens and those with HIV/AIDS or cystic fibrosis. Bronchiectasis, the bronchial condition which causes pathological enlargement of the bronchial tubes, is commonly found with MAI infection.
Plastic bronchitis bronchial casts [80] Plastic bronchitis is a rarely found condition in which thickened secretions plug the bronchi. [81] [82] The plugs are rubbery or plastic-feeling (thus the name). The light-colored plugs take the branching shape of the bronchi that they fill, and are known as bronchial casts. [81]
Asthma is an obstructive lung disease where the bronchial tubes (airways) are extra sensitive (hyperresponsive).The airways become inflamed and produce excess mucus and the muscles around the airways tighten making the airways narrower.
Figure A shows the location of the lungs and bronchial tubes. Figure B is an enlarged view of a normal bronchial tube. Figure C is an enlarged view of a bronchial tube with bronchitis.
