Several ELISA tests based on mycobacterial antigens have been used for the rapid diagnosis of tuberculosis (TB), although demonstration of Mycobacterium tuberculosis in a smear or culture is the most reliable method. In the present study, the diagnostic value of 16-kDa and 38-kDa mycobacterial antigens was investigated in patients who were diagnosed with tuberculosis by clinical and/or bacterio...

The specifity of gene encoding the ribotoxin protein in Aspergillus fumigatus was determined by PCR amplification of a portion of the gene. All A. fumigatus strains studied showed the presence of amplifiable ribotoxin product, while none of the other fungal species, with the exception of Aspergillus restrictus, showed this amplification product. Hence, this method may be used for rapid and spec...

BACKGROUND A retrospective analysis of 12 years' experience (1987-1999), concerning gastro-intestinal lymphomas (LNH-GI) has been performed, to offer a contribution for the identification of the diagnostic and prognostic criteria. METHODS During this period, 11 cases (9 male and 2 female) have been treated: 8 with gastric localization and 3 with intestinal localization, with age ranging betwe...

OBJECTIVES The detection of patients with comorbid mental disorders is of high clinical importance. Screening instruments can be recommended for early recognition. This study investigates the discriminant validity of the Hospital Anxiety and Depression Scale (HADS), General Health Questionnaire (GHQ-12) and Patient Health Questionnaire (Brief-PHQ-D) in chronically ill patients. METHODS Two hu...

BACKGROUND The proteolysis-inducing factor (PIF) was identified as a tumour product in various gastrointestinal cancers. A previous study in pancreatic cancer patients suggested PIF expression as a tumour marker, which is not related to tumour size. We hypothesized that PIF could be a useful marker to exclude benign pancreatic tumors, as chronic pancreatitis with a pancreatic mass. METHODS Ur...

The aim of this study was to investigate the value and significance of interleukin-8 in differentiation of uncomplicated parapneumonic effusion (UCPPE) from complicated parapneumonic effusion (CPPE). Using an IMMULITE 1000 Analyzer, with chemiluminescent immunometric assay, levels of interleukin-8 (IL-8) were measured in the pleural fluid of patients with UCPPE (n=30), and CPPE (n=30), and thre...
