background beta-thalassemia patients receive blood products from blood transfusion centers repeatedly. blood transfusion can transmit cytomegalovirus (cmv) and toxoplasma gondii. the aim of this study was serological evaluation of these two infectious agents in thalassemia patients. materials and methods in a cross-sectional study, the enzymelinked immunosorbent assay (elisa) testing was perfor...
abstract background multiple transfusions in thalassemia patients may lead to antibody production against blood group antigens and hemolytic transfusion reaction might occur. in this study, antibody screening test was performed by tube and gel methods to determine the prevalence and specificity of alloantibodies in thalassemia patients. materials and methods in this cross-sectional study, overa...

BACKGROUND Several screening tests are available to detect colorectal cancer (CRC) and reduce the incidence and mortality of CRC. The purpose of this review was to determine how current CRC screening strategies for CRC compare with no screening and whether agreement exists with regard to the cost effectiveness of different strategies. METHODS Databases were searched for cost-effectiveness ana...
PURPOSE Hypertension is the most common diagnosis in ambulatory care, yet little evidence exists regarding recommended screening intervals or the sensitivity and specificity of a routine office-based blood pressure measurement, the most common screening test.

Introduction: Complications of zinc poisoning are analyzed in several studies. Among these, pulmonary fibrosis are reported. There is some doubts about chronic complications of zinc inhalation. Precise screening programs in zinc mine workers need previous knowledge of relative frequency of chronic complications due to zinc inhalation. So this study is held to recognize the complications and to ...
