Specialty: Pulmonology: Symptoms: Cough with sputum, wheezing, shortness of breath, fever, chest discomfort [1] [2] Duration: Up to 6 weeks [3] Causes: Typically ...
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]
Pulmonary aspiration is the entry of solid or liquid material such as pharyngeal secretions, food, drink, or stomach contents from the oropharynx or gastrointestinal tract, into the trachea and lungs. [1] When pulmonary aspiration occurs during eating and drinking, the aspirated material is often colloquially referred to as "going down the ...
[5] [2] This was 4.8% of all deaths in 2013. [5] The World Health Organization has reported that, in 2021, "Lower respiratory infections remained the world’s most deadly communicable disease other than COVID-19, ranked as the fifth leading cause of death." However, the number of deaths caused has decreased by around 13% from 2000 to 2021. [6]
Mycobacterium avium-intracellulare infection (MAI) is an atypical mycobacterial infection, i.e. one with nontuberculous mycobacteria or NTM, caused by Mycobacterium avium complex (MAC), which is made of two Mycobacterium species, M. avium and M. intracellulare. [1]
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]
Bronchomalacia is a term for weak cartilage in the walls of the bronchial tubes, often occurring in children under a day. Bronchomalacia means 'floppiness' of some part of the bronchi. Patients present with noisy breathing and/or wheezing. There is collapse of a main stem bronchus on exhalation. If the trachea is also involved the term ...
One study in the US showed about a 0.09 to 0.29 per million increase in mortality rates although the cause specific cause was unclear. [8] Most of the outcomes collected are from patients diagnosed with farmer's or bird breeder's lung and thus the degree to which this data can be extrapolated to other types of HP is uncertain.
