Our study seeks the importanc.;e of "IFA" (Indirect Immuno Fluorescent Aniti body). Among 145 patients with amebic colitis Entamoeba hystolitica observed with reapeted and specified tests. In searh of serologic tests, antibody range in 20 patients who had amebic coliti...

The clinical value of using a new diagnostic test depends on whether it improves patient outcomes beyond the outcomes achieved using an old diagnostic test. When can studies of diagnostic test accuracy provide sufficient information to infer clinical value, and when do clinicians need to wait for results from randomized trials? The authors argue that accuracy studies suffice if a new diagnostic...

Background: Breast cancer is the most common type of cancer in women demanding accurate diagnosis to take remedial measures to treat.Objective: Comparing the diagnostic capability of the computer regulation thermography (CRT), as a novel and safe diagnostic procedure, with common methods including sonography, mammography and clinical examinations for diagnosing breast cancer in suspicious...
