The first step in the evaluation of patients with pleural effusion is to determine whether the effusion is a transudate or an exudate. An exudative effusion is diagnosed if the patient meets Light's criteria. The serum to pleural fluid protein or albumin gradients may help better categorize the occasional transudate misidentified as an exudate by these criteria. If the patient has a transudativ...

The pathological accumulation of serous fluids in the pleural, peritoneal and pericardial space occurs in a variety of conditions. Since patient management depends on right and timely diagnosis, biochemical analysis of extravascular body fluids is considered a valuable tool in the patient management process. The biochemical evaluation of serous fluids includes the determination of gross appeara...

A 53-year-old woman was admitted with right massive transudative pleural effusion and acute renal failure. The amount of pleural fluid reduced in response to treatment with hydration and diuretics; however, the effusion recurred one month later. We suspected the presence of a right pleuroperitoneal communication allowing pleural fluid to accumulate from an origin of ascites triggered by renal f...

A 52yearold woman with endstage renal disease for chronic glomerulonephritis was started on inpatient peritoneal dialysis (PD). We increased infusion volume of PD exchange every 2 days without observing any symptoms, including respiratory symptoms. After changing infusion volume on the 5th day, the patient complained of dyspnea and continuous cough. Decreased breath sounds were noted in the rig...

In this prospective study of 70 patients with pleural effusion, the underlying disease could be identified in 62 cases. By predefined criteria, 31 of these effusions were classified as transudates and 31 as exudates. Pleural fluid protein content, LDH activity and cholesterol level were measured to investigate their utility in differentiating the exudates from the transudates. Protein and LDH l...

Urinothorax (UT) is a rare and often undiagnosed condition, defined as the presence of urine in the pleural cavity due to the retroperitoneal leakage of urine accumulation, known as urinoma, into the pleural space. UT usually is a transudative pleural effusion that presents in patients with obstructive uropathy and it may occur following surgical procedures in the ureter or kidney such as ESWL,...

Here we report a 22-year old woman with massive and bilateral transudative effusion succeeded by pulmonary edema and brain edema and death. Investigations for systemic disorders were negative. Exacerbation of dyspnea after intravenous fluid infusion was a main problem. As effusion was refractory to medical treatment, the patient was referred for surgical pleurodesis and bilateral surgical pleur...

Pleural effusion is not a rare disease in Korea. The diagnosis of pleural effusion is very difficult, even though the patients often complain of typical symptoms indicating of pleural diseases. Pleural effusion is characterized by the pleural cavity filled with transudative or exudative pleural fluids, and it is developed by various etiologies. The presence of pleural effusion can be confirmed ...

Background: Pleural effusion is an excess fluid that accumulates between two pleural layers. analysis and cytology are the mainstays for diagnosing various pulmonary diseases. Levels of adenosine deaminase (ADA) particularly useful in areas where prevalence tuberculosis high. Objectives: To find clinical profile etiology respect age sex level different causes effusion. Materials Methods: This w...

Lactoferrin was analysed with an ELISA in pleural effusions from 21 patients with malignant exudative effusions (15 carcinomas and 6 mesotheliomas), 12 patients with non-malignant exudative effusions of unknown aetiology, 11 patients with transudative effusions due to congestive heart failure, 12 patients with exudative effusions secondary to infection, and 2 patients with tuberculous effusions...
