Xpert® MTB/RIF in pleural fluid for the diagnosis of tuberculosis.

The International Journal of Tuberculosis and Lung Disease, 2013
An automated nucleic acid amplification assay that simultaneously identifies Mycobacterium tuberculosis and rifampicin resistance, the Xpert® MTB/RIF test, has undergone extensive evaluation in sputum samples.

Can tuberculous pleural effusions be diagnosed by pleural fluid analysis alone?

The International Journal of Tuberculosis and Lung Disease, 2013
OBJECTIVE To assess whether pleural fluid analysis (PFA) can confidently diagnose tuberculous pleural effusion (TPE). METHODS PFA of 548 TPEs was performed between January 1991 and December 2011.

Antinuclear Antibodies in Pleural Fluid

Chest, 1994
Systemic lupus erythematosus (SLE) frequently involves the pleura with resultant pleural effusion. Previous studies have reported that detection of antinuclear antibodies (ANA) in pleural fluid using animal tissue as substrate was a sensitive and specific method for distinguishing SLE pleural effusions from other etiologies. The HEp-2 ANA, which uses a

Differentiating between feline pleural effusions of cardiac and non-cardiac origin using pleural fluid NT-proBNP concentrations.

Journal of Small Animal Practice, 2013
OBJECTIVE To assess whether pleural fluid and urine amino terminal proB-type natriuretic peptide (NT-proBNP) can distinguish cardiac from non-cardiac causes of pleural effusion.

Mucopolysaccharides of Serum and Pleural Fluid [PDF]

Nature, 1960
THE use of paper electrophoresis has enabled several investigators to establish the presence of acid mucopolysaccharide components in various tissue extracts1,2 and urine3. Two such substances, staining with toluidine blue, were found in human aortic tissue4; concentrated human urine contained three components which stained with alcian blue5.

The Effect of Pleural Fluid on the Diaphragm

Radiology, 1965
While many articles in the literature deal with the distribution and configuration of pleural effusion, there has been little discussion on the effects of this effusion on the dynamics of the diaphragm. As fluid accumulates in a pleural space, the corresponding hemidiaphragm may be depressed by the weight and pressure even though the upper level of the

Normoblasts in pleural fluid: Are they significant?

Diagnostic Cytopathology, 2007
AbstractThe hemopoietic cell elements in body fluids is a rare encounterance. From among the normal bone marrow inhabitants, only megakaryocytes are occasionally seen in pleural and peritoneal fluids due to extramedullary hemopoiesis as a result of myeloproliferative disorders.

Early Detection of Pleural Fluid

Chest, 1980
Displacement of a sharp "costophrenic angle," rather than blunting of the "costophrenic angle," is emphasized as one of the earliest signs of pleural fluid. Examples of this sign are illustrated, and its pathophysiology is discussed.

The Value of Pleural Fluid Analysis

The American Journal of the Medical Sciences, 2008
Pleural fluid analysis in isolation may have clinical value. To have the greatest diagnostic impact, the clinician must formulate a prethoracentesis diagnosis based on the clinical presentation, blood tests, and radiographic imaging. With this approach, a definitive or confident clinical diagnosis can be expected in up to 95% of patients.

Contribution of pleural fluid analysis to the diagnosis of pleural effusion

Medicina Clínica (English Edition), 2015
Analysis of pleural fluid can have, on its own, a high diagnostic value. In addition to thoracocentesis, a diagnostic hypothesis based on medical history, physical examination, blood analysis and imaging tests, the diagnostic effectiveness will significantly increase in order to establish a definite or high probable diagnosis in a substantial number of
