Adenoma Pleomorfo de Glándula Lagrimal: presentación de un caso clínico

Los tumores de la glándula lagrimal son raros. Se presenta el caso clínico de un paciente masculino de 69 años de edad que consulta por un tumor (Adenoma Pleomorfo) en la región orbitaria derecha, de un año de evolución. Se realizó la escisión quirúrgica del mismo y la recuperación del paciente fue muy satisfactoria, sin recidivas tras un año de seguimiento. Se realiza también una revisión de las características clínicas, radiográficas e histopatológicas de estos tumores.Lacrimal gland tumors are rare. We present a case of a 69 year old male patient with a one year history of an orbital tumor (Pleomorphic Adenoma ). The tumor was surgically enucleated and patient recovery was very satisfactory, with no signs of recurrence after one year of follow-up. A review of the clinical symptoms, radiologic features, treatment and histopathology of this kind of tumors is also made

Teacher Perceptions of Two Multi-Component Interventions: Disability Awareness and Science

This study investigated teachers’ perspectives about two interventions designed to promote kindergarteners’ attitudes toward peers with disabilities. Interviews with teachers were conducted following the 6-week interventions. Teachers shared views on the best and most difficult aspects of the interventions, perceived benefits for teachers and children, and suggestions for improving the interventions. Teachers’ responses were analyzed using content analysis. One salient teacher reported benefit was notable improvement in social skills made by all students. Moreover, students in the experimental condition displayed increased acceptance of peers with disabilities, whereas teachers reported becoming more confident discussing the topic of disability with students. Teachers also reported that although it was difficult to step back and observe children in cooperative learning groups, it was beneficial to see that when children were given opportunities to handle social situations on their own, many were capable of doing so. Implications for practice and recommendations for future research are discussed

Methods for evaluation of the antimicrobial activity and determination of Minimum Inhibitory Concentration (MIC) of plant extracts

Várias pesquisas vêm sendo desenvolvidas e direcionadas no descobrimento de novos agentes antimicrobianos provenientes de extratos de plantas e outros produtos naturais, para serem aplicados em produtos farmacêuticos e cosméticos. Atualmente, existem vários métodos para avaliar a atividade antibacteriana e antifúngica dos extratos vegetais. Os mais conhecidos incluem método de difusão em ágar, método de macrodiluição e microdiluição. A proposta dessa revisão é apresentar diferentes métodos comumente utilizados na pesquisa de novos agentes antimicrobianos, provenientes de extratos vegetais, e elucidar os principais fatores interferentes. Dessa maneira, contribuir como fonte de pesquisa para o desenvolvimento de futuros trabalhos relacionado ao estudo de atividade antimicrobiana de produtos naturais.Several researches have been developed to search for new antimicrobial agents from extracts of plants and other natural products to be used in pharmaceutical and cosmetic products. Nowadays there are many methods to evaluate the antibacterial and antifungal activity of the plant extracts. The most known assays have been based on diffusion in agar; and micro and macrodilution methods. The purpose of this review is to describe the different methods commonly used for the determination of new antimicrobial agents from the plants extracts and elucidate the main interference factors. Moreover, this contributes as research source for future development of investigations related to the study of antimicrobial activity from natural products.Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES)CNP

A sociodemographic and neuropsychological characterization of an illiterate population

The objectives of this article are to characterize the performance and to discuss the performance differences between literate and illiterate participants in a well-defined study population. We describe the participant-selection procedure used to investigate this population. Three groups with similar sociocultural backgrounds living in a relatively homogeneous fishing community in southern Portugal were characterized in terms of socioeconomic and sociocultural background variables and compared on a simple neuropsychological test battery; specifically, a literate group with more than 4 years of education (n = 9), a literate group with 4 years of education (n = 26), and an illiterate group (n = 31) were included in this study. We compare and discuss our results with other similar studies on the effects of literacy and illiteracy. The results indicate that naming and identification of real objects, verbal fluency using ecologically relevant semantic criteria, verbal memory, and orientation are not affected by literacy or level of formal education. In contrast, verbal working memory assessed with digit span, verbal abstraction, long-term semantic memory, and calculation (i.e., multiplication) are significantly affected by the level of literacy. We indicate that it is possible, with proper participant-selection procedures, to exclude general cognitive impairment and to control important sociocultural factors that potentially could introduce bias when studying the specific effects of literacy and level of formal education on cognitive brain function
