introduction: pulmonary embolism (pe) is a common lethal disease that its clinical symptoms may be seen in many other diseases. computed tomography pulmonary angiography (ctpa) is a valuable diagnostic modality for detection of pe. in addition, it can accurately detect the other diseases with clinical symptoms similar to pe. the aim of this study is to evaluate the frequency of pe and nonemboli...

Light's criteria (protein and LDH) have been used to the present to differentiate exudative pleural effusion from transudative. This is both time consuming and relatively more expensive as compared to measuring cholesterol. During 1992-1993, a prospective study on 70 patients with effusion was carried out measuring fasting LDH, protein, cholesterol, alkaline phosphatase and glucose. All pa...

Congenital chylothorax is an uncommon cause of respiratory distress and a life-threatening condition in newborns. It is identified by abnormal accumulation of chyle in the pleural space. Herein, we report a male infant who was born by a successful vaginal delivery. After the first three days of life, he had feeding difficulties and cyanotic episodes during breastfeeding. On admission, physical ...

Neoplastic diseases account for approximately 13% of the annual incidence of pleural effusions, and 75% of these effusions are secondary to malignancies of the lungs and breast or lymphoma. The most common pathogenic mechanisms that produce malignant pleural effusions (MPE) are (1) pleural metastasis resulting in increased membrane permeability beyond the capacity of lymphatic drainage, (2) met...

BACKGROUND High pleural fluid levels of neurone-specific enolase (NSE) have been reported, not only in patients with small cell lung cancer but also in those with chronic inflammatory diseases. METHODS NSE concentrations were determined in pleural fluid and serum from 342 patients with pleural effusions including 17 with rheumatoid arthritis. RESULTS The median NSE concentration in pleural ...

OBJECTIVE The diagnostic approach to pleural diseases may be difficult. The CT scan, which is the current diagnostic technique, has limited accuracy both in the differentiation between benign and malignant pleural diseases and in the diagnosis of primary and metastatic pleural neoplasms. Invasive procedures, such as thoracoscopy, are therefore frequently required to complete the diagnostic appr...

Adenosine deaminase activity (ADA) was assayed in pleural fluid and serum of 42 subjects with pleural effusion. Twenty-nine of them had TB pleural effusion and the remaining 13 had pleural effusion due to non-TB respiratory diseases. Serum adenosine deaminase activity were also measured in 32 pulmonary tuberculosis patients without pleural effusion and equal numbers of healthy controls without ...

  Background and Objectives:Infection of pleural fluid is a common disease and because of antibiotic administration, the microbiology of this fluid has changed. The aim of this study was to determine the common bacteria and suitable antibiotics for treatment in pleural effusion (PE). Materials and Methods: In this cross sectional study, 1210 samples with exudative features were cultured for p...

common radiologic features of lymphoma in lung are included: adenopathy, pleural effusion, multiple or solitary masses and diffuse infiltration. we want to present a 28y/o male with pulmonary hodgkin lymphoma with a rare radiographic pattern and distinct histologic description that at first misdiagnosed as pulmonary tuberculosis but eventually lung biopsy confirmed diagnosis of pulmonary hodgki...
