Chronic inflammation of the lungs is a key feature in aspiration pneumonia in elderly nursing home residents and presents as a sporadic fever (one day per week for several months). Radiological review shows chronic inflammation in the consolidated lung tissue, linking chronic micro-aspiration and chronic lung inflammation.
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 ...
Chronic intestinal pseudo-obstruction (CIPO) is a very rare syndrome with chronic and recurrent symptoms that suggest intestinal obstruction in the absence of any mechanical blockage of the lumen. [3] The most common symptoms of CIPO include abdominal pain, constipation, nausea, vomiting, dysphagia, and abdominal distention.
In adults, foreign body aspiration is often associated with an altered state of consciousness. The foreign body is often unchewed food, or part of a tooth or crown . [ 33 ] Bronchiectasis that results from foreign body aspiration generally occurs in the right lung in the lower lobe or posterior segments of the upper lobe.
With prompt treatment, outcomes are usually favorable. This is especially true for reversible conditions, like foreign body aspiration. [2] Chronic conditions, like vocal cord paralysis and sleep apnea, [7] may need ongoing care. If managed well, they usually have good outcomes.
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 ]
There are two general types of chemical pneumonitis: acute and chronic. Irritants capable of causing chemical pneumonitis include vomitus , [ 2 ] barium used in gastro-intestinal imaging, chlorine gas (among other pulmonary agents ), [ 2 ] ingested gasoline [ 2 ] or other petroleum distillates , ingested or skin absorbed pesticides , [ 2 ...
In both childhood and adult pneumonitis, hydrocarbon aspiration occurs at the time of initial ingestion event or subsequently with vomiting. Low viscosity of an ingested hydrocarbon is considered a major factor promoting aspiration (presumably for mechanical reasons).
