PURPOSE To evaluate the value of diffusion-weighted imaging (DWI) in the differential diagnosis of pleural effusions. MATERIALS AND METHODS 58 pleural effusions (21 transudative, 37 exudative) were included in this prospective study. Single-shot echo-planar spin echo DWI was performed with two b factors (500 and 1000 s/mm (2)), and apparent diffusion coefficients (ADCs) were calculated. On di...

A monoclonal antibody against soluble phase-terminal complement complex (SC5b-9) was used to try to differentiate pleural effusions of tuberculous vs malignant and other origin. Effusions of tuberculous origin showed a significantly higher SC5b-9 level than did plasma, suggesting activation of complement in the pleural space. All 26 patients with tuberculous effusions showed SC5b-9 levels in pl...

PURPOSE The purpose of this study was to analyze the expression of the high- and low-affinity nerve growth factor (NGF) receptors TrkA and p75 in effusions and in primary and metastatic tumors of serous ovarian carcinoma patients, as well as to evaluate their association with clinicopathological parameters and disease outcome. EXPERIMENTAL DESIGN Sections from 77 malignant effusions and 78 pr...

Pericardial effusion can develop in patients with acute pericarditis or association a wide variety of systemic diseases and is characterized as transudative, exudative, pyopericardium, hemopericardium. Large effusions are usually related to tuberculous neoplastic effusions. Primary pericardial tumors rare, the vast majority cases resulting from secondary tumors. may be present 7% 53% cancer cor...

BACKGROUND Fine-needle aspiration cytology (FNAC) of serous membrane effusions may fulfil a challenging role in the diagnostic analysis of both primary and metastatic disease. From this perspective, liquid-based cytology (LBC) represents a feasible and reliable method for empowering the performance of ancillary techniques (ie, immunocytochemistry and molecular testing) with high diagnostic accu...

PURPOSE OF REVIEW Pleural effusions commonly occur in patients with left heart failure. However, there is increasing evidence that patients with pulmonary hypertension and isolated right heart failure frequently have pleural effusions. RECENT FINDINGS Three recent studies have evaluated the incidence of pleural effusions without an alternate explanation in patients with idiopathic/familial pu...

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...

Objectives To find the incidence of pleural effusions among patients with Mycoplasma pneumoniae pneumonia. Design Prospective study Setting University paediatric unit, Karapitiya, Galle. Method Patients with pneumonia admitted to university paediatric unit from November 1998 to October 1999 were included. Pleural effusions were confirmed either radiologically or by ultrasound examination. Large...

Parapneumonic effusions in children with community-acquired pneumonia (CAP) often prolong the period of ill-health and may be associated with increased mortality. This study set out to determine the patterns, risk factors, aetiology, and outcome of parapneumonic effusions among children admitted with CAP at a tertiary health facility in south-west Nigeria. All cases of childhood pneumonia, incl...
