Localization is the first step in osteoarthritis (OA) classification. Manual classification, however, is time-consuming, tedious, and expensive. The proposed system is designed as decision support system for medical doctors to classify the severity of knee OA. A method has been proposed here to localize a joint space area for OA and then classify it in 4 steps to classify OA into KL-Grade 0, KL...

BACKGROUND Nuclear sclerosis (NS) based on the Emery-Little classification and refractive values after lens-sparing vitrectomy was compared between proliferative diabetic retinopathy (DR) patients and nondiabetic patients. METHODS Progression of NS based on the Emery-Little classification and changes in refractive values were compared between 13 proliferative DR patients (14 eyes, DR group) a...

Purpose. The study was undertaken to evaluate a novel classification system developed to estimate financial cost of bile duct injury (BDI) and to aid in decision making for referral. Study Design. A retrospective review of patients referred for BDI was performed. Grade I injuries involve the duct of Luschka or accessory right hepatic ducts, grade II includes all other biliary injuries, and grad...

BACKGROUND A classification of lumbosacral spondylolisthesis has been proposed recently. This classification describes eight distinct types of spondylolisthesis based on the slip grade, the degree of dysplasia, and the sagittal sacro-pelvic balance. The objectives of this study are to assess the reliability of this classification and to propose a new and refined classification. METHODS Standi...

This paper extends the line of research that considers the application of Artificial Neural Networks (ANNs) as an automated system, for the assignment of tumors grade. One hundred twenty nine cases were classified according to the WHO grading system by experienced pathologists in three classes: Grade I, Grade II and Grade III. 36 morphological and textural, cell nuclei features represented each...

  Background: The role of arthroscopic partial meniscectomy (APM) for painful degenerative meniscal tears (PDMT) is currently controversial. To define the rate of early (1 to 5 years) conversion to total knee replacement (TKR) and their predictors after APM for PDMT in patients with knee osteoarthritis and more than 50 years of age. Methods: Retrospective cohort study of patients more than...

  Background and Objectives: Gliomas are the most prevalent primary brain tumors. The purpose of this retrospective cohort study was evaluation of clinical trend and prognosis of patients with brain glioma and effective factors in prognosis. Materials and Methods: Hundred and forty-five patients with supratentorial brain glioma, treated in Shahid Mostafa Khomeini & Hazrat-e-...

AIM To analyse whether the mean nuclear area of the 10 largest nuclei (MNA-10), the mitotic activity index (MAI), and Ki-67 immunoquantitative features have additional value to discriminate different grades of T(A,1) transitional cell carcinoma (TCC) of the urinary bladder. MATERIALS/METHODS One hundred and fifty of 200 consecutive cases (75%) showing interobserver agreement on duplicate blin...

OBJECTIVES We proposed that the severity of ST-segment elevation myocardial infarction (STEMI) could be classified based on pathophysiological changes. METHODS First-STEMI patients were classified within hospitalization. Grade 0: no detectable myocardial necrosis; Grade 1: myocardial necrosis without functional and morphological abnormalities; Grade 2: myocardial necrosis with reduced LVEF; G...
