Background Endometriosis has been widely implicated as one of the causes of chronic pelvic pain, dysmenorrhea and infertility. The purpose of our study was to define the presumed correlation between visual and histologic diagnostic features of endometriosis based on the peritoneal findings identified in laparoscopy as a diagnostic trial with a standardized technique. So, all the specimens inclu...

In this article, a new combined approach of a decision tree and clustering is presented to predict the transmission of genetic diseases. In this article, the performance of these algorithms is compared for more accurate prediction of disease transmission under the same condition and based on a series of measures like the positive predictive value, negative predictive value, accuracy, sensitivit...
abstract background: regarding the diagnostic errors of the classic criteria including serum ascites albumin gradient (saag), total protein concentration and the adapted light et al’s criteria in distinguishing transudate versus exudates, we evaluated the ascitic fluid to serum bilirubin ratio as a new criteria in this regard. we also evaluated whether the combination of bilirubin ratio with ea...
background and objectives: thyroid gland because of its superficial location is amenable to direct physical examination. clinical assessment of thyroid lesions by means of physical examination, thyroid scans and ultrasonography is not completely reliable. fine needle aspiration cytology (fnac) is the most cost-effective, safe and an initial diagnostic test in the pre-operative evaluation of thy...

Background: Currently, non-invasive methods for screening atrophic gastritis and gastric cancer are lacking. The purpose of this study was to evaluate the value of serological parameters including serum pepsinogen I (PGI), pepsinogen II (PGII) and pepsinogen I: II ratio for the screening atrophic gastritis and gastric cancer. Methods : The study population consisted of 132 dyspeptic patient...
