background: helicobacter pylori (h. pylori) infection is a major cause of chronic gastritis, especially in metabolic syndrome patients. the use of a accessible and easy diagnostic method, can speed up the treatment of this infection this study compared two methods of histology and serology for diagnosis of h. pylori in metabolic syndrome patients. methods : this study was done on 175 metabolic ...

In “Possible Estuary-Associated Syndrome: Symptoms, Vision, and Treatment,” Shoemaker and Hudnell (1) advocated use of the visual contrast sensitivity (VCS) test as a biomarker to diagnose possible estuaryassociated syndrome (PEAS) and to assess response to their proposed treatment regimen. However, the use of VCS as a diagnostic test for PEAS (and subsequent treatment of PEAS with cholestyrami...

In recent years, rapid diagnostic tests (RDTs) have been widely used for malaria detection, primarily because of their simple operation, fast results, and straightforward interpretation. The Asan EasyTest™ Malaria Pf/Pan Ag is one of the most commonly used malaria RDTs in several countries, including Korea and India. In this study, we tested the diagnostic performance of this RDT in Uganda to e...

Diagnostic testing is essential to distinguish non-diseased individuals from diseased individuals. More accurate tests lead to improved treatment and thus reduce medical mistakes. The sensitivity and specificity are two important measurements for the diagnostic accuracy of a diagnostic test. When the test results are continuous, it is of interest to construct a confidence interval for the sensi...

Fifty three bile specimens from 42 patients were reviewed to assess the diagnostic role of the bile cytology and to define more reliable cytologic indicators of malignancy. Forty three bile specimens came from 34 patients with malignant biliary strictures and 10 bile specimens were from eight patients with benign conditions. There were no false positives. The diagnostic specificity of bile cyto...

Imprecise usage of the terms "sensitivity" and "specificity" produces confusion in the diagnostic use of sophisticated laboratory test results. "Analytical sensitivity" represents the smallest amount of substance in a sample that can accurately be measured by an assay. "Analytical specificity" refers to the ability of an assay to measure on particular organism or substance, rather than others, ...

PURPOSE To evaluate the diagnostic accuracy of real-time neck computed tomography (CT)-guided ultrasonography (US) in detecting cervical neck lymph node metastasis (LNM) in patients with papillary thyroid cancer (PTC). METHODS We retrospectively reviewed data from 176 patients (mean age, 43 years; range, 23 to 74 years) with surgically confirmed PTC who underwent preoperative US, neck CT, and...
