BACKGROUND AND PURPOSE Different methods have been used to classify osteoarthritis (OA) of the hip. We evaluated the reliability of different classifications in order to find which grading system is most appropriate for use in clinical practice. PATIENTS AND METHODS 49 patients (61 affected hips) with late-detected developmental dislocation of the hip (DDH) were studied. The mean age at follo...

Aim: Accurate classification of diabetic foot ulcers is essential for inter-clinician communication, assessment of healing tendency, and determination of treatment options. Ulcer classification is performed by many different caregivers involved, but their agreement is unclear. The aim of this study was to assess the inter-observer agreement (IOA) of the most commonly used classification systems...

INTRODUCTION In Non-Hodgkin Lymphoma (NHL), bone marrow histology is the gold standard against which ancillary investigations such as immunophenotyping and gene rearrangement studies are interpreted. There is currently no data on the reproducibility of histological findings. This study was conducted to determine the rates of inter- and intra-observer agreement in histological detection of bone ...

objective: diagnosis of vertical root fractures (vrfs) is critical in endodontics. cone beam computed tomography (cbct)  has significantly enhanced image quality compared to digital radiography (dr) and greatly aids the diagnosis of vrfs but, metal artifacts has remained as a problem in vrf detection.  this study evaluated the effect of intra canal posts on the diagnostic accuracy of cbct and d...

background: the i-space is a radiological imaging system in which computed tomography (ct)-scans can be evaluated as a three dimensional hologram. the aim of this study is to analyze the value of virtual reality (i-space) in diagnosing acute occult scaphoid fractures.   methods: a convenient cohort of 24 patients with a ct-scan from prior studies, without a scaphoid fracture on radiograph, yet ...

BACKGROUND Endoscopic findings are essential in evaluating the disease activity in ulcerative colitis. The aim of this study was to evaluate how endoscopists assess individual endoscopic features of mucosal inflammation in ulcerative colitis, the inter-observer agreement, and the importance of the observers' experience. METHODS Five video clips of ulcerative colitis were shown to a group of e...

The description of various methods for ethnicity classification can be found in the literature, though their reliability still remains unclear. We examined inter-observer agreement in defining the ethnic identification of patients in a bi-ethnic population (Arab-Jewish) in northern Israel, using place of birth and residence in addition to given and family names. Data about 1006 consecutive pati...

PURPOSE To develop a cross-cultural Ocular Surface Disease Index (OSDI) for the Brazilian population and analyze its validity and effectiveness. METHODS Based on the guidelines of Guillemin et al., four English teachers, an ophthalmologist, a rheumatologist, two ophthalmology residents and a native American who does not speak Portuguese were invited. The procedure followed the steps: translat...
