Pleural Fluid and Histologic Analysis
Although talc slurry pleurodesis is effective for control of malignant pleural effusions and recurrent pneumothorax, the mechanisms of pleurodesis remain incompletely defined. We instilled 70 mg/kg of sterile asbestos-free talc slurry into the pleural space of New Zealand white rabbits and studied the inflammatory response at 1, 2, 3, 7, 15, 30, 60, 90, and 120 days by observing pleural fluid a...
متن کاملRole of Pleural Fluid Cea Level in Pleural Fluid Analysis Abstract
Pleural fluid cytology is usually the initial diagnostic tool in pleural fluid analysis. However, the conventional cytological evaluation of pleural effusion in detecting malignancy has a sensitivity wide range – from 22 to 81%. Measurement of carcinoembryogenic antigen (CEA) level in pleural fluid may be valuable in the diagnosis of malignant pleural effusion. The study was performed on 70 dif...
متن کاملGetting the most from pleural fluid analysis.
Virtually, every pulmonary disease and most non-pulmonary diseases may be associated with a pleural effusion. The presence of a pleural effusion allows the clinician to 'diagnose' or narrow the differential diagnosis and aetiology of the fluid collection. However, pleural fluid analysis (PFA) in isolation rarely provides a definitive diagnosis. This review discusses the rationale for evaluating...
متن کاملThe Art of Pleural Fluid Analysis
Although a pleural effusion (PE) is a common condition in clinical practice (with a prevalence of slightly > 400 patients/100,000), a definitive diagnosis is not established in approximately 20% of cases. In the classic publications, thoracentesis provided a definitive or presumptive diagnosis in 73% of cases, although it is estimated that today this percentage could reach 95%. An undiagnosed P...
متن کاملQuality Assurance in the Preanalytical Phase
The preanalytical phase includes a set of processes that are difficult to define because they take place in different places and at different times. Classically, the preanalytical phase included all processes from the time a laboratory request is made by a physician until the sample is ready for testing. While this definition is very informative, errors that occur at this stage often become app...
