Formação de professores é um desafio que ultrapassa fronteiras de espaço e tempo. No caso da formação inicial, as dificuldades de articular necessidades formativas oriundas do campo de atuação às possibilidades dos cursos que formam o professor se mantêm. Buscando contribuir para minimizá-las, realizou-se uma investigação, cujos objetivos foram: investigar processos de aprendizagem da docência e evidenciar concepções de futuros professores sobre a sua profissão. Formulou-se um questionário com perguntas abertas, respondido por vinte estudantes do último ano de licenciatura de uma universidade pública do interior paulista, de cursos distintos. Os dados foram analisados em seis eixos temáticos, resultando em significativas constatações, das quais se destaca a falta de saberes relativos à especificidade da profissão docente e ao contexto sócio-histórico no qual ela acontece, comprometendo a ação futura do professor e, consequentemente, a aprendizagem do aluno da escola básica. Cabe, pois, repensar a formação docente, numa época em que seu redimensionamento por meios tecnológicos é possível.

A literatura que descreve os resultados das correções cirúrgicas nos tecidos moles é limitada, pois apresenta significativa variação e não oferece conclusões definitivas. O propósito desse artigo é estudar retrospectivamente os efeitos das cirurgias ortognáticas maxilares tipo Le Fort I nos lábios superiores e inferiores de pacientes adultos e discutir os potenciais problemas envolvidos com a metodologia aplicada. Foram estudados 19 pacientes brancos de 19 a 42 anos de idade, sendo 10 homens e 9 mulheres, submetidos a cirurgias maxilares no Centro de Pesquisa e Tratamento das Deformidades Buco-Faciais - CEDEFACE (Araraquara, SP). A grande maioria dos casos apresentou, no mínimo, uma discrepância significativa, seja ântero-posterior ou vertical, reforçando a sua indicação cirúrgica. As alterações nos tecidos moles foram significativas quando as movimentações horizontais ou verticais da base óssea maxilar foram significativas, com uma relação de aproximadamente 0,6:1 entre as alterações ântero-posteriores do lábio superior e a movimentação da base óssea. Alterações verticais na maxila, sem significativas alterações horizontais, não foram suficientes para aumentar verticalmente o lábio superior. Ocorreram alterações ântero-posteriores do lábio inferior em conseqüência do deslocamento anterior e inferior da maxila, o que permitiu um melhor selamento labial. Alterações verticais não foram quantificadas no lábio inferior.

OBJETIVO: o avanço maxilomandibular é um método cirúrgico comumente usado no tratamento de pacientes acometidos pela Síndrome da Apnéia Obstrutiva do Sono (SAOS) e portadores de anormalidades anatômicas identificáveis neste complexo, que estreitam e/ou obstruem o espaço aéreo. O intuito deste estudo foi analisar variações cefalométricas do espaço aéreo faríngeo em indivíduos Classe II de Angle, após a cirurgia ortognática. METODOLOGIA: a amostra consistiu de telerradiografias laterais equivalentes aos períodos pré e pós-operatório de 30 indivíduos, divididos no grupo com avanço cirúrgico mandibular (n=15) e no grupo com avanço maxilomandibular (n=15). Os parâmetros cefalométricos usados permitiram avaliar o espaço aéreo posterior em 3 níveis: a hipofaringe (PFI-V), a orofaringe (PFM-PM, PFM-PO, PFM-U, PFM-Up) e a nasofaringe (PFM-PN, pm-PFS). A análise esquelética foi na base do crânio (N-S-Ba) e na mandíbula (Ar-Go-Me). A média das diferenças entre os valores pré e pós-operatórios das mensurações lineares (mm) e angulares (graus) foi avaliada pelo teste t pareado. RESULTADOS E CONCLUSÕES: estatisticamente, não houve redução do espaço aéreo faríngeo pós-avanço cirúrgico. O que se observou foi que apenas PFM-PO e PFS-pM se mantiveram constantes e na maioria restante os valores aumentaram.

CONTEXTO: A síndrome de Alport é responsável por aproximadamente 5% dos pacientes com insuficiência renal crônica. Nessa doença, anormalidades no sistema de condução cardíaco são mais freqüentes que na população em geral. OBJETIVO: Relatar caso de síndrome de Alport que desenvolveu bloqueio atrioventricular total durante um transplante renal. RELATO DE CASO: Paciente masculino, 21 anos de idade, com insuficiência renal crônica secundária à síndrome de Alport, foi submetido a transplante renal sob anestesia peridural. Durante o procedimento anestésico-cirúrgico apresentou bloqueio atrioventricular total, que foi tratado rapidamente, e com sucesso, usando-se um marcapasso transcutâneo. O bloqueio simpático extenso pode contribuir para o desenvolvimento de distúrbios no sistema de condução cardíaco, particularmente em pacientes com insuficiência renal crônica em esquema de diálise. Mesmo em pacientes com eletrocardiograma pré-operatório normal e sem distúrbios de condução, graus variáveis de bloqueio atrioventricular, incluindo bloqueio atrioventricular total, podem ocorrer. Nesse caso, o uso de marcapasso transcutâneo é tratamento rápido e efetivo na sala de operação até o final da cirurgia, quando o tratamento definitivo pode ser planejado.

Objective: There is strong evidence that methylene blue (MB), an inhibitor of guanylate cyclase, is an excellent therapeutic option for vasoplegic syndrome (VS) treatment in heart surgery. The aim of this article is to review the MB's therapeutic function in the vasoplegic syndrome treatment. Methods: Fifteen years of literature review. Results: 1) Heparin and ACE inhibitors are risk factors; 2) In the recommended doses it is safe (the lethal dose is 40 mg/ kg); 3) The use of MB does not cause endothelial dysfunction; 4) The MB effect appears in cases of nitric oxide (NO) up-regulation; 5) MB is not a vasoconstrictor, by blocking of the GMPc system it releases the AMPc system, facilitating the norepinephrine vasoconstrictor effect; 6) The most used dosage is 2 mg/kg as IV bolus followed by the same continuous infusion because plasmatic concentrations strongly decays in the first 40 minutes; 7) There is a possible window of opportunity for the MB's effectiveness. Conclusions: Although there are no definitive multicentric studies, the MB used to treat heart surgery VS, at the present time, is the best, safest and cheapest option, being a Brazilian contribution for the heart surgery.

Introduction: The surgery of keloids as an individual therapy with high rates of recurrence needs adjuvant therapies as complement. Recent keloids are rich in fibroblasts, which are highly radiosensitive and what explains the good results of percutaneous radiotherapy after surgery. Objective: To compare the beta-therapy results with electron-beam technique in newly operated keloids. Material and Methods: a prospective, comparative and randomized study was outlined including patients in the immediate postoperative period of surgical excision of keloids. Divided in G1 and G2 groups respectively, they received treatment with Sr90 (beta-therapy)plates or with electrons from the linear accelerator. The monitoring lasted 10 years. The results were performed using the information from patients, photograph parameters, observation and measurement of injuries, according to the criteria: Unchanged, Regular, Good and Excellent. Results: There were 26 patients, 13 in each group. In G1, 54% presented regular and unchanged improvement criteria and 46% had good or excellent criteria. In G2, the results were respectively 23% and 77%. Conclusion: The irradiation with electron-beam is better than beta-teraphy for the treatment of keloids surgery, due to the distribution in the tissue. No radio-induced tumors were observed.

Objective: The objective of this study is to characterize the assistance and analyze patient's adherence to nutritional follow-up while in the waiting line for bariatric surgery in a multidisciplinary, secondary healthcare outpatient clinic. Methods: This retrospective study was based on the nutritional records of 59 patients subjected to bariatric surgery at the Hospital das Clinics de Botucatu, from 2001 to 2008. The population studied was distributed into 8 groups and analyzed according to follow-up duration. The analysis took into account the evolution of body weight and the number of follow-up visits in a given period. The Kruskal-Wallis test was used to compare data between groups while Spearman's coefficient was used to test correlations. Results: Among the 59 studied patients, 42 (71.2%) returned to the clinic at least once in six months. Of these, 67.8% lost weight while in the waiting line and 27.1% of them lost more than 10% of their body weight. The greatest weight losses in the preoperative period were found in the groups that had more than six months of nutrition follow-up. There was a mean delay of three months between return visits, which could have contributed to the low adherence to follow-up. Conclusion: The patients in the waiting line for surgery analyzed in this study presented low adherence to the long-spaced return visits. The greatest weight losses were observed in groups that had been followed for more than six months. This shows that, to achieve the desired weight loss and an adequate education process before surgery, at least six months of follow-up and regular visits are necessary.

Mohs Micrographic Surgery is regarded as a very useful technique for the excision of difficult to han- dle skin cancers. The procedure is divided into clearly defined steps: tumor evaluation and marking, tumor exeresis, tissue preparation and mapping, histologic processing and analysis, and closing of the surgical wound. The histologic analysis of all surgical margins leads to higher cure rates and tissue conservation, which make the procedure safer and more reliable.

This article discusses the awareness process of students in a Spanish as a foreign language classroom, at a Centre of Language Studies in a city in the state of São Paulo, Brazil. The frame of reference is Paulo Freire's pedagogy (FREIRE, 1980, 1984, 1987, 1999, 2000), Wallerstein (1983) and Schleppegrell (1997)'s investigations which are important to the comprehension of the relation between Freirean's pedagogy and the language teaching. This is a qualitative research and it focuses on action research practice in a Spanish language classroom, in which a syllabus based on Paulo Freire's pedagogy was implemented in order to verify how the target language was used in the classroom (MENEGHINI, 2001). Data analysis and discussion are based on data triangulation and classroom interactions are taken on primary data. The implementation of this research suggests that the problem posing tasks on themes chosen from the student's realities are the way which leads to the awareness.
