A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...
Depending on eosinophil target-organ infiltration, the clinical presentation of hypereosinophilic syndrome (HES) varies from patient to patient. [13] Individuals with myeloproliferative variant HES may be more likely to experience mucosal ulcerations involving the genitalia or airways, while patients with lymphocytic variant HES typically exhibit prominent skin symptoms such as urticarial ...
Eosinophilic pneumonia is diagnosed in one of three circumstances: when a complete blood count reveals increased eosinophils and a chest X-ray or computed tomography identifies abnormalities in the lungs, when a biopsy identifies increased eosinophils in lung tissue, or when increased eosinophils are found in fluid obtained by a bronchoscopy ...
Finally in 1943 the condition was called tropical eosinophilia by RJ Weingarten, and later officially named Löffler's syndrome. [3] The most well-known case of Löffler's syndrome was in a young boy from Louisiana. He arrived at the hospital reporting a high fever after three days, as well as having rapid breathing.
Eosinophilia is a condition in which the eosinophil count in the peripheral blood exceeds 5 × 10 8 /L (500/μL). [1] Hypereosinophilia is an elevation in an individual's circulating blood eosinophil count above 1.5 × 10 9 /L (i.e. 1,500/μL).
Acute eosinophilic pneumonia (AEP) is an uncommon, acute-onset form of eosinophilic lung disease which varies in severity. Though poorly understood, the pathogenesis of AEP likely varies depending on the underlying cause which may include smoking, inhalation exposure, medication, and infection. [ 1 ]
In some cases of pleural effusion, the excess fluid becomes infected and turns into an abscess. This is called an empyema. Pleural effusion involving fibrinous exudates in the fluid may be called fibrinous pleurisy, which sometimes occurs as a later stage of pleurisy. A person can develop a pleural effusion in the absence of pleurisy.
Pleural effusion and empyema - Microorganisms from the lung may trigger fluid collection in the pleural cavity, or empyema. Pleural fluid, if present, should be collected with a needle and examined. Depending on the results, complete drainage of the fluid with a chest tube may be necessary to prevent proliferation of the infection. Antibiotics ...
