this study was aimed at determining intra and inter-observer concordance rates in the gleason scoring of prostatic adenocarcinoma, before and after a web-based educational course. in this self-controlled study, 150 tissue samples of prostatic adenocarcinoma are re-examined to be scored according to the gleason scoring system. then all pathologists attend a free web-based course. afterwards, the...

  Background: Knee malalignment is an important modifiable cause of osteoarthritis (OA). Surgical therapeutic procedures depend on proper knee alignment assessment. The purpose of this study was to compare knee alignment parameters between double and single leg weight-bearing radiographs and to evaluate the reproducibility of inter- and intra-observer measurements. Methods: One hundred eight p...

AIMS Myocardial velocity imaging has been validated in adults for assessment of ventricular function and indirect indices of pulmonary arterial pressure. To establish whether it could also be used in infants, we investigated the reproducibility of myocardial velocities and deformation indices in term and preterm neonates. METHODS AND RESULTS Myocardial velocity loops acquired from 16 infants ...

PURPOSE To measure the level of inter/intra-observer reproducibility among pathologists as far as Gleason scoring of adenocarcinoma of the prostate is concerned. MATERIALS AND METHODS A total of 101 prostate biopsy slides, diagnosed with adenocarcinoma of the prostate by five pathologists from different education centers, were exposed to Gleason scoring. Two months later, the slides were re-e...

PURPOSE To evaluate intraobserver and interobserver reproducibility of measurement of images obtained during ultrasound biomicroscopy. METHODS Four anterior segment images of four normal patients were obtained by a single examiner. The measurements of three independent observers were compared to assess interobserver reproducibility in quantifying the images. Thirteen different anterior segmen...

The purpose of this pilot study was to assess whether orthodontic treatment planning is reproducible when carried out using digital records compared with clinical examinations or using standard records. The study also assessed patients' opinion of face-to-face consultations and potential use of teleorthodontics. The study was designed as a prospective observational cross-sectional pilot study a...

Introduction: Managing the acute admission of older patients is a challenge in hospitals. Frail older people represent a larger proportion of acute admissions. Length of inpatient stay, inpatient mortality and the 90-day readmission rate are significant in this group of patients. In order to reduce the risks of adverse outcomes, frailty should be screened using an appropriate assessment tool an...

OBJECTIVES The present study was conducted to determine the reproducibility of peri-implant tissue assessment using the new implant success index (ISI) in comparison with the Misch classification. MATERIALS AND METHODS In this descriptive study, 22 cases of peri-implant soft tissue with different conditions were selected, and color slides were prepared from them. The slides were shown to peri...

The reproducibility of the AO classification for distal radius fractures remains a topic of debate. Previous studies showed variable reproducibility results. Important treatment decisions depend on correct classification, especially in comminuted, intra-articular fractures. Therefore, reliable reproducibility results need to be undisputedly determined. Hence, the study objective was to assess i...

results inter-observer agreement of the pathology scores based on nas scoring system was acceptable for steatosis, lobular inflammation, and fibrosis, but not for hepatocyte ballooning. the intra-observer agreement was acceptable in all scales, with lowest intra-class correlation observed for lobular inflammation. materials and methods the anonymous liver biopsy samples of 100 consecutive nafld...
