Acute interstitial pneumonitis (also known as acute interstitial pneumonia) is a rare, severe lung disease that usually affects otherwise healthy individuals. There is no known cause or cure. There is no known cause or cure.
Aspiration pneumonia most often develops due to micro-aspiration of saliva, or bacteria carried on food and liquids, in combination with impaired host immune function. [30] 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 ...
Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [ 1 ] [ 2 ] [ 3 ] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
Broad spectrum antibiotic to cover mixed flora is the mainstay of treatment. Pulmonary physiotherapy and postural drainage are also important. Surgical procedures are required in selective patients for drainage or pulmonary resection. The treatment is divided according to the type of abscess, acute or chronic.
Chest X-rays can be useful in the diagnosis of aspiration pneumonia but may be negative early in the course. [12] Chest CT Scan can identify the presence of a pneumonia as well, and can also assist in characterizing abscesses, foreign objects, or pleural disease. Aspiration seen on barium swallow study.
Pneumonia can be described as pneumonitis combined with consolidation and exudation of lung tissue due to infection with microorganisms. [5] The distinction between pneumonia and pneumonitis can be further understood with pneumonitis being the encapsulation of all respiratory infections (incorporating pneumonia and pulmonary fibrosis as major ...
The sooner the endotracheal tube is removed, the lower the risk of pneumonia, but if it is removed too early and has to be put back in, the risk of pneumonia rises. [39] People who are at risk for pulmonary aspiration (e.g. those with lowered level of consciousness due to head injuries) are especially likely to get pneumonia. [39]
Hydrocarbon pneumonia is an acute hemorrhagic necrotizing disease that can develop within 24 h after the ingestion. Pneumonia may require several weeks for complete resolution. [2] Symptoms of chemical (hydrocarbon) pneumonia may include: [3] burning of the nose, eyes, lips, mouth, and throat; dry cough; wet cough producing clear, yellow, or ...
