Frequency of Blastocystis hominis and other intestinal parasites in stool samples examined at the Parasitology Laboratory of the School of Pharmaceutical Sciences at the São Paulo State University, Araraquara

Blastocystis hominis é um protozoário, causador de infecção intestinal denominada blastocistose humana, cujo diagnóstico é realizado pelo exame coproparasitológico e por meio de técnicas de coloração permanente. Este estudo foi desenvolvido para avaliar a freqüência da infecção por Blastocystis hominis em habitantes da região de Araraquara/SP, bem como comparar diferentes métodos para a pesquisa desse protozoário em amostras de fezes. Foram estudadas 503 amostras de fezes submetidas ao exame direto a fresco, às técnicas de Faust e cols, Lutz e de Rugai e cols, além das colorações pela hematoxilina férrica, tricrômio e de Kinyoun modificada. Entre as 503 amostras examinadas, 174 (34,6%) apresentaram-se positivas para a presença de parasitas intestinais. O protozoário e o helminto mais freqüentes foram Entamoeba coli (14,6%) e Strongyloides stercoralis (6,7%), respectivamente. Blastocystis hominis foi observado em 23 (4,6%) amostras fecais com consistência predominantemente pastosa, não caracterizando quadro diarréico. Apesar da baixa freqüência de Blastocystis hominis encontrada na região de Araraquara, comparativamente a outras regiões brasileiras, é importante a realização do diagnóstico laboratorial desse protozoário. O encontro de Blastocystis hominis em material fecal é indicativo de contaminação de alimentos e água de consumo, desde que se admita a rota de transmissão oral-fecal desse parasita, o que implica na orientação da população sobre as medidas de saneamento básico e higiene como meio para se controlar problemas de saúde ocasionados pelos enteroparasitas.

Paracoccidioidomycosis: Survey and clinical aspects from the Department of Dermatology of the School of Medicine of Botucatu (Sao Paulo - Brazil)

Background - Paracoccidioidomycosis is the most frequent among the systemic mycoses in Brazil. Objective: To study the cases of paracoccidioidomycosis diagnosed from 1976 to 1996 at the Department of Dermatology of the School of Medicine of Botucatu. Methods - Descriptive study obtained from specific protocols comprising anamnesis, clinical- dermatological-laboratorial examination, treatment and follow-up of the patients. Results - Paracoccidioidomycosis was diagnosed in 1.04% of the dermatologic outpatients assisted from 1976 to 1996. In 315 cases, 89.8% were male, 61.9% were over forty and 53.7% were rural workers. The complaints were related more to oropharyngolaryngeal (53.6%) or cutaneous (23.8%) lesions or adenopathy (10.2%). Seventy patients had already been treated in other health services. The chronic multifocal clinical from was the most common: 80.6% of the cases, followed by the acute-subacute (juvenile type) 15.5%. The disease was pulmonary in 80.0%, oropharyngolaryngeal in 69.2% and cutaneous in 45.7%. Th treatment: Amphotericin B in 146 patients, Ketoconazole - 88, Itraconazole - 56, Sulfonamide derivatives - 146 and Terbinafine in 3. The lethality index resulting from the disease or its treatment was 2.0%. Conclusions - The high number of cases, showing the regional relevance of the disease and the high percentage of tegumentary complaints and the high number of relapsing are remarkable.

Particle Physics in the teaching practice of the participants of the School of Physics CERN

A atualização dos currículos escolares e, em especial, a inserção de assuntos de física moderna e contemporânea já foram defendidos com justificativas satisfatórias, tanto por professores em atividade escolar como por pesquisadores da área de ensino de física. Entre os assuntos que deveriam ser discutidos encontramos a Física das Partículas Elementares. O ensino deste tópico é justificado pelo fato dele permitir a discussão: a) de uma nova visão de mundo; b) de uma visão mais adequada da ciência; c) da reinterpretação da Física Clássica; d) da dinâmica da Ciência e seu desenvolvimento; e) da contribuição dos diversos cientistas; f) do papel da experimentação; g) do investimento financeiro e cooperativo de diversos países e pesquisadores. No entanto, para que a inserção de assuntos de física moderna e contemporânea ocorra de maneira eficiente é necessária a atualização dos professores que já estão em docência escolar, bem como uma formação adequada daqueles que estão em processo de formação inicial. Neste sentido, desde 2010 a Sociedade Brasileira de Física realiza anualmente a Escola de Física do CERN, na qual participam professores brasileiros de física de escolas públicas do Ensino Médio. Nesta escola são desenvolvidas aulas sobre física de partículas, sessões experimentais e visitas aos laboratórios do CERN. Perante isso, investigamos como os professores participantes da Escola de Física do CERN abordam a física de partículas em suas aulas após participarem dela.

Profile of the production engineer student at a school of engineering in Brazil: academic and professional trajectories and tendencies

The objective of this paper is to introduce a study on the academic trajectory and professional profile of production engineers who graduated in a traditional and renowned Brazilian University (School of Engineering at Bauru – FEB). The study was conducted with the first three classes of undergraduates in the production engineering program at FEB/UNESP. A 50% response rate was obtained and with the data collected it was possible to characterize the professional profile of the students and outline their academic trajectory. According to the sample, the main result is that the curricular grid is the main criterion of similarity in student education, thus, the focus on program improvements should focus on the curricular grid. Tendencies are also pointed out to guide the search for improvements in the academic trajectory of production engineering students.

Good afternoon. Thank you for asking me to be with you today; I welcome this opportunity to talk with you, to hear what you're thinking, and to participate with you in an exchange of ideas. I've been asked to make some prepared remarks this afternoon, and when those are ended I welcome your ideas, your questions, and your comments. I look forward to more discussions with you at other times, as well. I do have open hours Friday afternoons, and encourage faculty and staff to stop by to visit, to share an idea, to ask a question, or to just visit. Sometimes duties call me away, as they will for the next few Fridays, but I try to be available as many Friday afternoons as possible for drop-in visitors. I hope you'll be among them. As a big believer in the land grant university, with our mission of teaching, research, and extension education, I also am a big believer that it takes all of us, working together, to fulfill that mission.

French-Brazilian school of nephrology

The recent history of French and Brazilian medicine goes back to the first decades of the xixth century. As regards nephrology, the first links were established starting in the 1950s of the xxth century. Over the past 60 years, the scientific production of the Franco-Brazilian school of nephrology totalized more than a thousand scientific papers and created a new generation of more than two hundred disciples, formed in Brazil by nephrologists who had completed their studies in France. In this article, we would like to memorize the successive exchanges between French and Brazilian physicians, mainly in the field of nephrology. (C) 2012 Association Societe de nephrologie.
