Changing profile of infective endocarditis during a 20-year observation period.

Background: Infective endocarditis (IE) is most often caused by bacteria.

Objectives: The aim of this work is the research of the dynamics of the clinical laboratory and instrumental methods of the diagnostics during the period of two decades.

Methods: The data of 241 patients with infective endocarditis (IE) who were treated at the State Clinical Hospital named after Botkin S.

Polyp detection with computer-aided diagnosis in white light colonoscopy: comparison of three different methods.

Detection of polyps during colonoscopy is essential for screening colorectal cancer and computer-aided-diagnosis (CAD) could be helpful for this objective. The goal of this study was to assess the efficacy of CAD in detection of polyps in video colonoscopy by using three methods we have proposed and applied for diagnosis of polyps in wireless capsule colonoscopy. Forty-two patients were included in the study, each one bearing one polyp.

Automated polyp detection in colon capsule endoscopy.

Colorectal polyps are important precursors to colon cancer, a major health problem. Colon capsule endoscopy is a safe and minimally invasive examination procedure, in which the images of the intestine are obtained via digital cameras on board of a small capsule ingested by a patient. The video sequence is then analyzed for the presence of polyps.
