BACKGROUND AND OBJECTIVE The aims of this study were to describe the frequency and radiographical characteristics of pleural effusions in a large population of patients with acute pulmonary embolism (PE) and characterize the pleural fluid biochemistry in those patients who underwent diagnostic thoracentesis. METHODS This was a retrospective observational(More)
STUDY OBJECTIVE The diagnostic value of tumor markers in pleural fluid is subject to debate. The aim of this study was to evaluate the diagnostic performance of several tumor markers in common use for detecting malignant pleural disease. DESIGN Blinded comparison of four tumor markers in pleural fluid with a confirmatory diagnosis of malignancy by pleural(More)
BACKGROUND To determine the effects of the biochemical and cytological properties of the pleural fluid (PF) on the survival of patients with malignant pleural effusion (MPE). METHODS A retrospective study of 284 patients with MPE was performed, which measured overall survival, survival of patients with different types of primary tumors, and survival as a(More)
In this retrospective study of 80 pleural effusions, the combination of thyroid transcription factor 1 (TTF-1) and napsin A immunostaining on fluid cell blocks was positive in 80% of lung adenocarcinomas. Although measuring TTF-1 pleural fluid concentrations was of no value, quantification of napsin A levels allowed the identification of one third of the(More)
STUDY OBJECTIVES To determine whether the detection of pneumococcal antigen in pleural fluid augments conventional microbiological methods used for the etiologic diagnosis of pneumonia. METHODS In this retrospective study, a rapid immunochromatographic test (ICT) [NOW Streptococcus pneumoniae assay; Binax; Scarborough, ME] was performed on pleural fluid(More)
OBJECTIVE To determine the diagnostic utility of adenosine deaminase (ADA) in a large series of pleural effusions of different etiologies. METHODS A retrospective study of 2104 consecutive patients presenting with pleural effusion was carried out at a Spanish university hospital. ADA levels in pleural fluid were determined using a non-Giusti automatic(More)
BACKGROUND The aim of this study was to characterize the clinical characteristics and insulin secretion in adults with latent autoimmune diabetes in adults (LADA). We also compared these characteristics in subjects with antibody-negative type 2 diabetes (T2DM) or adult-onset type 1 diabetes (T1DM) to subjects with LADA. METHODS In this cross-sectional(More)
BACKGROUND AND OBJECTIVE Light's criteria misclassify a quarter of transudates as exudates. We assessed the influence of red blood cell counts on pleural lactate dehydrogenase (LDH) levels and, thereby, on the specificity of Light's criteria. PATIENTS AND METHOD We retrospectively reviewed 1,312 consecutive patients with pleural effusion, of whom 1,014(More)
OBJECTIVE To investigate the etiology of pleural effusions (PE) in adults and the accuracy of pleural fluid (PF) cytology and cultures in malignant and infectious PE, respectively. PATIENTS AND METHODS Retrospective analysis of all consecutive patients with PE undergoing diagnostic thoracentesis during the last 19 years in a university hospital. RESULTS(More)
