Avaliação das doses de cães submetidos a exames radiográficos de pulmão

This study aims to determine surface skin doses in dogs (with suspected pulmonary metastasis) submitted to chest X-rays using the technique of thermoluminescence dosimetry. Twenty seven exams from different dogs were performed at the Faculdade de Medicina Veterinária e Zootecnia da Universidade Estadual Paulista (FMVZ-UNESP/Botucatu). The doses were evaluated using thermoluminescent dosimeters of calcium sulphate doped with dysprosium (CaSO4:Dy) produced by the Instituto de Pesquisas Energéticas e Nucleares (IPEN-CNEN). The pulmonary metastasis exams are carried out in three projections, one dorsal-ventral and two lateral-lateral. During the procedures the projection thicknesses and source-skin surface distances were registered. To simulate the dog phantom the dosimeters were positioned in a cubic simulator (30x30x30 cm) of polymethylmethacrylate (PMMA) filled with water and irradiated according to the parameters of projections with the X-ray energies ranging from 45 to 70 kV. To estimate the surface skin dose the dose-response curves were obtained for X-ray energies of 50 and 70 kV using the diagnostic X-ray beam machine of the Instruments Calibration Laboratory of IPEN for doses of 1.5, 2.0, 2.5, 3.5 and 4.0 mGy. The main difficulty of this work was the dog immobilization that is reflected in poor-quality diagnostic imaging and, consequently, demands the repetition of the exams, which contributes to the increase of the doses received by the animals being studied and the clinical staff. The doses evaluated in this type of procedure are between 0.43 and 4.22 mGy. This research has shown to be extremely important for the assessment of doses involved in veterinary diagnostic radiology procedures, and as a parameter in the individual monitoring of pet’s owners who assist the animal positioning and occupationally exposed workers of the Department of Veterinary Radiology

Gama Câmara CZT: alteração de paradigmas em aquisição de imagens de medicina nuclear

Nuclear medicine is a medical specialty related to imagery that deals with imaging techniques, diagnosis and therapy, allowing observing the physiological state of tissues noninvasively by marking the molecules participating of these physiological processes with radioactive isotopes, thus creating the called radionuclides. The image of a radionuclide is one of the most important applications of radioactivity in nuclear medicine. The equipment’s of nuclear medicine imaging use the principle of radiation detection, turning it into an electrical signal which, through specific algorithms, allows forming tomographic images that provide information about the functional status of organs. New detection systems have been developed for tomographic acquisitions using solid state detectors. These devices use crystals of cadmium zinc telluride (CdZnTe). Some of the advantages of this detector are a significant improvement of signal to noise ratio, the increased spectral and spatial resolution, which in sum, result in greater clarity of the images obtained, opening new perspectives for imaging protocols previously unattainable. In contrast, all other gamma-cameras equipped with vacuum tubes have remained relatively unchanged for nearly fifty years. In these gamma-cameras, the images are obtained using two steps significantly less efficient: the gamma rays are converted to light through a first device, and then the light is converted into an electrical signal through a second device. One of functions the Medical Physicist is related to the quality control of equipment. This control ensures that the information and images provided are true and thus credible to be used in medical reports. To perform this type of analysis the physicist must understand the performance characteristics and operation of all equipment of the department concerned; besides, in the absence of specific legislation, proposing...(Complete abstract click electronic access below)

Competences in the classroom in the perspectives of foreign language teachers

In this article we raise some considerations about teachers’ competences, from the perspective of teachers in the Brazilian public sector. The theoretical framework includes articles by Paulo Freire (2001), Philippe Perrenoud (2012), Edgar Morin (2003) and Maurice Tardif (2002) and, based on these authors, we reflect upon issues concerning teachers’ competences taking answers provided by the Brazilian language teachers as a departing point. In a teachers’ course, followed by the same teachers, we posed the main question in our study: Which competences are necessary for a teacher to be considered a good professional at present? From the answers given individually and group discussions we proceeded to a comparative analysis with the adopted framework, and other issues concerning teachers’ competences were considered as well. All the participants mentioned the same two competences, the use of technology and sound knowledge of the course content, and other competences were pointed out by the various teachers as well. Such procedure, besides providing data for our study, also helped as a self-reflexive activity for the teachers involved, about their own professional performance. Given the issues raised in the theoretical texts and the answers provided by the teachers, we expect to revisit the competences necessary for foreign language teacher efficient performance.

Critérios diagnóstico para a cardiomiopatia arritmogênica do ventrículo direito em cães: revisão sistemática

A cardiomiopatia arritmogênica do ventrículo direito (CAVD) é uma enfermidade de caráter hereditário na qual há uma lenta e progressiva degeneração do miocárdio. As apresentações clínicas podem variar desde um animal saudável, assintomático, a episódios de síncope, fraqueza, intolerância ao exercício, tosse e aumento de volume abdominal. Visto a dificuldade diagnóstica devido às variações na forma de apresentação da doença e os diferentes achados de exames complementares, esta revisão sistemática tem como objetivo definir o melhor critério diagnóstico para a CAVD. Um total de 24 artigos foi utilizado, sendo que 18 destes relatavam o critério diagnóstico utilizado. O melhor exame complementar encontrado foi o eletrocardiograma (Holter-24 horas), no qual animais que apresentam mais de 1000 contrações ventriculares prematuras (CVPs) em 24 horas são considerados doentes

Gengivite Plasmocitária induzida por uso de pimenta

The aim of this case report is present a case in which the patient had plasma cell gingivitis induced by consumption of pepper. Patient A.M.S., male, 23 years, presented himself at the Clinic of Periodontology, complaining of severe pain, bleeding gums and tooth mobility. Interview was conducted not observing anything relevant. In oral evaluation, we observed in the anterior swollen gums, bleeding, suppuration and great touch, and tooth mobility. Being an aggressive framework in relation to patient age, we performed the following laboratory tests: complete blood count, blood sugar, and coagulation, and biopsy in the anterior inferior, because a diagnosis of lymphoma. At the end of antibiotic therapy, a significant improvement of clinical symptoms, pain relief, less swollen gums and reduce the suppuration and mobility. Laboratory tests showed no change. Fifteen days later, the patient returned with worsening of clinical status. The pathological diagnosis was plasma cell gingivitis and then performed a new history by placing greater emphasis on dietary habits, and the patient reported consumption of pepper in their meals, and relate this to clinical presentation. After elimination of pepper diet the patient showed remission of clinical data.

Avaliação de um curso sobre internet para terceira idade

The aim of this study was to evaluate the learning of Senior Citizens after a face-to-face course with the goal of teaching them how to use the internet. The study population was composed of people (n=18), of both genders, aged 50 years or over, from the open university for Senior Citizens UNATI (“Universidade Aberta da Terceira Idade” in Portuguese) at Araraquara. Two hour classes weekly were taught in the computer laboratory - LDI in Portuguese located in the School of Dentistry in Araraquara. The course program content covered the use of e-mail and researches in sites. In order to evaluate the learning acquired, a self-evaluation questionnaire was applied in twice (before and after the course), which enabled the development of students concerning their knowledge and skill in the topics approached in classes. Descriptive statistical analysis was performed. The average performance of participants was calculated per point and interval of confidence of 95% (IC95%) in the beginning and in the end of the course. Comparison between the averages was performed by using the paired Student’s-t test. The level of significance adopted was 5%. It was observed that the students’ learning about computer use improved significantly after the course (Student’s-t test: -5.360, p<0.001, p2=0.628, =0,999), however, 72.2% of them reported that they did not know how to attach a file to a message to be sent by e-mail, as well as having no or little skill to perform this activity. It was concluded that the evaluated course improved the participants knowledge and skills in computer use.

Os limites e as possibilidades de uma sequência didática: o conceito de proporcionalidade e a aprendizagem de alunos do 5º ano do Ensino Fundamental

This study aimed to analyze the limits and possibilities of a didactic sequence, addressing the concept of proportionality in the learning of students in 5th year of elementary school. From the results of the Diagnostic Assessment Initial applied to students in a class of 5th grade of elementary school, we selected eight (8) students who participated in the constituent activities of that instructional sequence. For the development of this sequence were used theoretical elements of Genetic Epistemology (Piaget, 1990), the theory of fields of Conceptual Vergnaud (1996) and the definition of instructional sequence proposed by Zabala (1998). Finally, after 20 days of application of these activities, we applied the Diagnostic Assessment Final aimed at investigating which concepts related to proportionality were built by the participating students. By analyzing the collected data, it can be concluded the following about the possibilities of teaching sequence: 1) students who, in Diagnostica Home Assessment used the multiplication algorithm, but also did not indicate the comparison between quantities are now performing; 2) students who, in the Diagnostic Assessment Initial, used the addition algorithm, now gradually are using the multiplication algorithm; 3)students who, in the Diagnostic Assessment Initial, could not solve problems involving the idea of proportionality, are now resolving, however, still use, in large part, the addition operation as a strategy for this proportional thinking. Now, in relation to the limits of the sequence noted: 1)time sufficient to propose a higher number of problem conditions to be carried by students who may have been a trigger of construction have not through the proportional multiplication;2)the distant proposition situations of assimilation schemes (interpretation) of the students, which may have caused certain imbalance in them, preventing them from thinking about the problem situation;3)the rapid passage of...

Implicações de um programa de formação continuada na formação e atuação de professores de educação física atuantes no ciclo I

This work focused on research a course of continuing education for teachers of Physical Education, offered in a city of São Paulo in 2013. Adopting as a benchmark analysis of models of continuing education in teaching, investigative question that guided this study was: what are the implications of this formative process in the formation and performance of the participating teachers?. With this guiding question, four were the objectives we seek to respond to this analysis: first identify the profile of teachers as well as the participation and involvement of the same course developed; 2 map and analyze the manifestations of teachers throughout the course; 3 reflect on the role of teachers in relation to approaches and/or distances with the common physical education curriculum proposed by the municipality; 4 identify and analyze the reflections on the course conducted. The methodological approach was qualitative and eighteen participants were teachers of a school system in a city of São Paulo, active in cycle I (1 to 5 years) of primary school. Data collection was carried out in two phases, with the participants in the first stage seventeen teachers and three teachers in the second stage that in addition to acting in the cycle I also actively participated in the course. Data were obtained in phase one using a diagnostic interview recorded on voice recorder and transcripts of observations and recorded in video and voice recorder from sixteen meetings of the continuing education course conducted in 2013 and phase two included the observation of classes teachers in the 2nd half of 2013, ending with a final interview. Demonstrations of physical education teachers in the course, as well as the situations observed and interviews indicated that on the profile of teachers are in the age range 30-58 years to serve at least five years in schools and most (10) does not work elsewhere. Another observation is that most of the participating teachers when thes...

O surgimento das práticas de assistência à saúde mental da criança inspiradas na psicanálise no início do século XX através da obra de Durval Bellegard Marcondes

Psychoanalysis was introduced in Brazil since 1920 contributing to the appearance of new practices of health care for the child. Therefore, the present article aims to discuss the link between psychoanalysis and practices focused on children's mental health that emerged from the 1930s through the work of Durval Marcondes, a pioneer in the dissemination and use of psychoanalysis in Brazil. A historical research was held from a survey on Durval Marcondes’s work and the team led by him confined in the epigraph theme. It was found from that work that the link between mental hygiene, new school and psychoanalysis developed a pioneering service of care to children with school problems based on the diagnostic evaluation and guidance of parents and teachers. It is concluded that this work introduced the differentiation between children with cognitive and emotional problems and provided the foundations of psychoeducational and psycodiagnostic interventions.
