PURPOSE to evaluate the agreement between histopathologic diagnoses of breast lesions made by general pathologists and by a specialist in breast pathology. METHODS a cohort retrospective study comparing histopathologic diagnoses of 329 cases of breast lesions received in consultation for a second opinion was carried out. The material received for consultation included slides (152 cases), para...

The study of reliability was part of a project funded by the Grant Agency of the Czech Ministry of Health. The repeatability of answers, 180 questionnaires being sent again after a six week interval, was assessed by two methods: by the percentages of agreement and using the Kappa index. We evaluated 61 questions, which were divided into five sections (general questions, questions on employment,...

BACKGROUND Very little is known about concordance of Toxoplasma gondii (T. gondii) infection markers among couples. Through a cross-sectional study, we sought to determine the correlation of T. gondii infection in a sample of 119 heterosexual couples in Durango State, Mexico. METHODS Participants were examined for the presence of anti-T. gondii IgG and IgM antibodies using enzyme-linked immun...

Background Increased locomotor activity in response to the same stimulus is an index of behavioral sensitization observed in preclinical models of drug addiction and compulsive behaviors. Repeated administration of quinpirole, a D2/D3 dopamine agonist, induces locomotor sensitization. This effect is potentiated and accelerated by co-administration of U69593, a kappa opioid receptor agonist. The...

Non-Maxwellian $\kappa$ electron energy distributions (EEDs) have been proposed in recent years to resolve the so-called ``electron temperature and abundance discrepancy problem'' study of planetary nebulae (PNe). Thus need develop diagnostic tools determine from observations EED PNe is raised. Arising high levels, ultraviolet (UV) emission lines present intensities that depend sensitively on h...

BACKGROUND Multiple sclerosis (MS) initiates with a first attack or clinically isolated syndrome (CIS). The importance of an early treatment in MS leads to the search, as soon as possible, for novel biomarkers which can predict conversion from CIS to MS. OBJECTIVE The purpose of this study was to assess the predictive value of the kappa index ([Formula: see text] index), using kappa free ligh...

This article aims to evaluate the reliability of the data available in the Information System for Live Birth (SINASC) in the city of Teresina, Piauí State, Brazil for the year of 2002. The proportion of data completeness was analyzed, and concordance between variables for data reported to SINASC and hospital records (SINASC-P) was estimated using the kappa index. This study demonstrated that va...

OBJECTIVE : To assess intra- and interobserver reproducibility of Sanders Classification System of calcaneal fractures among experienced and less experienced observers. METHODS : Forty-six CT scans of intra-articular calcaneal fractures were reviewed. Four observers, two with ten years of experience in foot and ankle surgery and two third-year residents in Orthopedics and Traumatology classif...

BACKGROUND This study aimed to assess inter-observer variability between the original diagnostic reports and later review by a specialist in breast pathology considering lobular neoplasias (LN), columnar cell lesions (CCL), atypical ductal hyperplasia (ADH), and ductal carcinoma in situ (DCIS) of the breast. METHODS A retrospective, observational, cross-sectional study was conducted. A total ...

Malocclusion assessment methods are based on registrations and measurements made on study casts, which requires that impressions be taken. In addition to being costly and time-consuming, this process can be unpleasant for very young children. Therefore, the aim of this study was to evaluate the reliability of intra-oral measurements that compute a malocclusion index score to determine malocclus...
