In adults, the right lower lobe of the lung is the most common site of recurrent pneumonia in foreign body aspiration. [2] This is due to the fact that the anatomy of the right main bronchus is wider and steeper than that of the left main bronchus, allowing objects to enter more easily than the left side. [ 2 ]
Radiation pneumonitis occurs in approximately 30% of advanced lung cancer patients treated with radiation therapy. [16] Aspiration pneumonitis is caused by a chemical inhalation of harmful gastric contents which include causes such as: Aspiration due to a drug overdose [17] A lung injury after the inhalation of habitual gastric contents.

The causes of upper airway obstructions can be acute or chronic. Acute causes of upper airway obstruction include foreign body aspiration, blunt trauma to the neck, infection, and swelling due to allergies or other inflammatory conditions. [3] In children, viral infections such as croup or epiglottitis are frequent causes. [4]
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]
In IPF patients, the overall mortality at 5 years rate is high but the annual rate of all-cause mortality in patients with mild to moderate lung impairment is relatively low. This is the reason why change in lung function (FVC) is usually measured in 1-year clinical trials of IPF treatments rather than survival. [69]
The standard drug treatment of dexamethasone does not alter the hypoxia or the consequent vasoconstriction, but stimulates fluid reabsorption in the lungs to reverse the edema. Additionally, several studies on native populations remaining at high altitudes have demonstrated to varying degrees the blunting of the HPV response.
The study of the differences in taste perception between the sexes is still largely unexplored, but what we were able to uncover may surprise you. Check out the slideshow above to find out if men ...
In older adults, risk factors also include living alone, wearing dentures, and having difficulty swallowing. [18] Children and adults with neurological, cognitive, or psychiatric disorders are at an increased risk of choking [17] and may experience a delay in diagnosis because there may not be a known history of a foreign body entering the ...
