Medical students often encounter patients with pleural effusion during internships and their residency. These patients do not always suffer from dyspnea and an accurate clinical examination is crucial for the diagnosis. In oral and written exams, explaining the difference between transudate and exudate is a frequent task. In this article, you can find all the important information regarding ple...

background: accumulation of pleural and peritoneal fluid is seen in some diseases. in order to diagnose the disease and start the treatment, one of the most important actions will be to differentiate between exudates and transudates. the objective of this study was to determine the diagnostic value of measuring the specific gravity of the fluid through refractometer and strip in differentiation...

Endogenous interstitial adenosine may protect the hypoxic heart by attenuating ,B-adrenergic-induced contractile and metabolic responses, thereby reducing energy utilization. Constant-flow perfused rat hearts were used to study 1) the effect of hypoxia on isoproterenol (ISO)-induced increase in interstitial adenosine, as estimated with epicardial surface transudates, and 2) the role of endogeno...

Localized fibrous tumours of the pleura (or localized benign mesothelioma) are rare, and in most cases, asymptomatic. This report describes a 48 yr old female with a right-sided fibrous pleural tumour, which produced 171 L of transudate before a correct diagnosis was reached. The tumour was surgically removed and the transudation stopped immediately.

Endogenous interstitial adenosine may protect the hypoxic heart by attenuating beta-adrenergic-induced contractile and metabolic responses, thereby reducing energy utilization. Constant-flow perfused rat hearts were used to study: 1) the effect of hypoxia on isoproterenol (ISO)-induced increase in interstitial adenosine, as estimated with epicardial surface transudates, and 2) the role of endog...

OBJECTIVES The usefulness of biochemical criteria to separate pleural transudates from exudates is controversial, and the limitations of Light's criteria in patients receiving diuretic therapy is of general concern. We evaluated the added value of biochemical criteria to clinical judgment for separating transudates from exudates. SETTING A community teaching hospital. DESIGN A prospective, ...

Adenosine (ADO) has an antiadrenergic action in the heart that causes an attenuation of contractile and metabolic responses elicited by fi-adrenergic stimulation. The effect of an increase in oxygen consumption elicited by either f-adrenergic stimulation or an increase in contraction frequency on interstitial fluid and coronary effluent ADO levels was investigated in isolated perfused isovolumi...
