Email for distance diagnosis of oral diseases: a preliminary study of teledentistry.

Abstract: We examined the feasibility of distance diagnosis of oral diseases, using transmission of digital images by email. Twenty-five cases of oral lesions were documented during a 12-month study in a primary care public health clinic in Parana in Southern Brazil. Clinical electronic charts and images were produced and sent by email to two oral medicine specialists with a median of 10 years experience in the field. The consultants provided a maximum of two clinical hypotheses for each case. In 15 of the 25 cases (60%) both consultants made a correct diagnosis; in seven cases (28%) only one consultant made a correct diagnosis; and in three cases (12%) neither consultant made a correct diagnosis. Thus in 88% of cases, at least one consultant was able to provide the correct diagnosis. The results suggest that distant diagnosis can be an effective alternative in the diagnosis of oral lesions and that the using two distant consultants improves diagnostic accuracy. Primary care public health clinics may benefit from t...

Aspectos estruturais da cooperação entre pesquisadores no campo de administração pública e gestão social: análise das redes entre instituições no Brasil

Abstract: Este artigo verifica, por meio da analise de redes, a estrutura de relacionamento entre instituicoes de pesquisa no campo de administracao publica e gestao social no Brasil. O relacionamento entre instituicoes de pesquisa foi obtido com base nas afiliacoes institucionais dos autores pela analise de 549 artigos publicados nos anais do Enanpad, entre 2000 e 2005. Com o uso dos softwares Ucinet 6.0 e Pajek 1.10, foi elaborada a rede de relacoes da area e foi possivel verificar tanto as propriedades estruturais e posicionais da rede, quanto avaliar a influencia da estrutura da rede na producao cientifica. Verificou-se que, apesar de a densidade da rede ser baixa, a distância entre as instituicoes e pequena, com grande componente principal. Pode-se afirmar que, na maioria dos casos, as instituicoes que apresentam maior numero de lacos estao mais globalmente centralizadas e tambem sao importantes elos de coesao na rede. Observou-se que a maioria dos lacos acontece entre instituicoes do proprio estado. Pode-se tambem afirmar que a estrutura da rede tem relacao direta com os indicadores de producao cientifica.

Práticas didático-pedagógicas no ensino de empreendedorismo em cursos de graduação e pós-graduação nacionais e internacionais

Abstract: The aim of this article is to provide state-of-the-art didactic-pedagogical practices used in the entrepreneurship education of national and foreign under graduation and graduation courses and to prove or refute them through the practices adopted by a post-graduation course in Business Management of a university at Curitiba. Firstly, a historic description of the entrepreneurship education in the universities has been developed as well as its importance in the social economic development of the countries and in the generation of innovations, followed by an explanation of its current situation in the world and in Brazil. In a second stage was outlined the methodology, seeking analyze the main publications on the topic of entrepreneurship education. They were searched in all its contents of the publication, the annals: Enanpad and Egepe; and international periodics: Journal of Business Venturing and Education + Training. They were reviewed, although, publications of the authors of domestic and foreign most authoritative on the subject, as well as other important international journals that address the topic of entrepreneurial training, but not through a general review of publications. The main results show that: the universities are implementing the entrepreneurship education in their curricular grades using more efficient didactic-pedagogical practices, but not putting aside, in most of the times, the traditional methods of education; the professor therefore shall establish a balance between the roles of facilitating and teaching in the process of learning; the professors' former experience and work in small companies will help the students in the process of learning and undertaking. However, it is important to mention, that the incubators are essential for the implementation of the business plans developed by the students.

Thermal behavior of corn starch granules modified by acid treatment at 30 and 50°C

Abstract: Unprocessed native starches are structurally too weak and functionally too restricted for application in today's advanced food technologies. Processing is necessary to engender a range of functionality. Naturals or natives starches can be modified by using several methods physical, chemical, enzymatic or combined, according industrial purposes. In this work, native corn starch was hydrolyzed by hydrochloric acid solution and investigated by using thermoanalytical techniques (thermogravimetry - TG, differential thermal analysis - DTA and differential scanning calorimetry - DSC), as well as optical microscopy and X-ray diffractometry. After acid treatment at 30 and 50°C, a decrease of gelatinization enthalpy (ΔHgel) was verified. Optical microscopy and X-ray diffractometry allowed us to verify the granules contorn and rugosity typical of cereal starches.

Periódicos Brasileiros de Administração: Análise Bibliométrica de Impacto no Triênio 2005-2007

Abstract: This article deals with the evaluation of scientific periodicals from the field of Administration in Brazil, based on the use of the concept of the impact factor vis-a-vis their classification in the CAPES Qualis System. We seek to discuss the applicability of the impact factor as an instrument that ensures new guidelines for gauging quality. To this end, twenty-one periodicals and the Enanpad annals covering the period of 2005 to 2007 were analyzed. The periodicals were divided into three groups: ‘A’ Recent Domestic (made up of periodicals which were assigned the ‘A’ status in 2007); ‘A’ Traditional Domestic (made up of periodicals which have had the ‘A’ status for some time); and ‘B’ Domestic. The results show a significantly higher concentration of quotes and the impact factor for the group designated as ‘A’ Traditional Domestic. We did not find any significant difference concerning the impact factor in the other groups. This finding has some inconsistencies pertaining to the concepts obtained from Qualis-CAPES in 2007 by the other two groups. In addition, we did not find any significant influence of selfquoting in the annals of Enanpads or the temporal window for calculating the impact factor. These results enabled us to reach a conclusion on the viability of the use of the impact factor as a relevant criterion in the evaluation policy of periodicals. This is not about considering the unidimensional quality concept but rather about recognizing that the repercussion of a periodical reflects the interest sparked by the articles published in it in the construction of scientific knowledge

The Influence of Corporate Relationships Networks on the Performance of Firms in the Novo Mercado of BOVESPA

Abstract: The role played by the board of a firm is one of the main aspects considered in literature on corporate governance around of the world. simultaneously, the social and institutional relations have been seen as preponderant factor for the happened results of the performance of such boards of big companies. However not yet research is verified that analyze the role of the boards from the Social Network Analysis (SNA) in Brazil. In this manner, this study aims to verify the existence of associations between centrality level, density and cohesion of the boards of Brazilian companies and firmperformance. Then, we evaluate 615 individuals, that had formed the boards of the 90 listed companies in the Novo Mercado of the S˜ao Paulo Stock Exchange in 2007. The analysis was lead in two phases. In the first one we present the configuration of the networks of board members, in second place, we verify associations between structure of the network and performance. It was verified that the centrality, density and the cohesion of the firms, in terms of its board members, are related with performance, some times in terms of Return Over Assets (Roa), some times in debt. Of this form, we conclude that organizations most located in the networks of corporative relations tend to present greater yield and minor debt.

Estrutura de relacionamento entre instituições de pesquisa do campo de Ciência e Tecnologia no Brasil

Abstract: In this study we map out the structure of relationships between research institutions in the field of science and technology in Brazil, by analyzing 688 articles published in Enanpad and in the Management Symposium of Technological Innovation, between 2000 and 2005. Based on co-authorship we verified that the field is a great network in which more than half of the institutions are connected, thereby creating social capital. Some institutions also stand out because they have a great number of collaborators, because they form bridges between different groups and because they maintain durable relationships, with indications of homophylia, the geographic locations and institutional role of which condition peer relationships. Finally, the productivity of these institutions is influenced by the cooperation that exists between them.

Perfil dos farmacêuticos e farmácias em Santa Catarina: indicadores de estrutura e processo

Abstract: The present study aimed to assess structure and process quality indicators in community pharmacies in Santa Catarina (Brazil), and also the profile of pharmacists regarding their attitudes and perceptions of pharmaceutical care and professional satisfaction. A cross-sectional study was performed in 10% of Santa Catarina pharmacies randomly chosen. 258 community pharmacies were surveyed. 88.5% pharmacists were in office in the time of the interview. In average, they were 31 years old (SD=8.1) and mainly women (68%). A ratio of 1.4 (SD=0.7) pharmacists per pharmacy and 3.8 (SD=4.5) assistants existed. Only 11.4% pharmacies had an adequate structure for private caring patients. Despite having an average of more than 2 tertiary drug information sources, most of them were low quality. Activities mentioned by the majority of pharmacists were dispensing (98.2%), recording controlled drugs (90.8%), injections administration (85.1%), and helping patients on cash line (84.2%). Most of pharmacies in Santa Catarina (Brazil) do not have the adequate structure for implementing pharmaceutical care services. Barriers identified to implement those services were not different to those communicated in other countries.

Abstract: This work had as aim to evaluate the effects of foliar application of Ascophyllum nodosum extract, L-glutamic acid and Ca +2 , alone or in mixed solutions, over growth and grain production of common bean ( Phaseolus vulgaris L.). The research was carried out in greenhouse with the following treatments: without application; solution with 60 g L -1 L-glutamic acid; solution with 60 g L -1 extract; solution of CaCl 2 with 100 g L -1 de Ca +2 ; mixed solution with 30 g L -1 L-glutamic acid, and 30 g L -1 extract; mixed solution with 30 g L -1 L-glutamic acid and 100 g L -1 Ca +2 in CaCl 2 form; mixed solution with 30 g L -1 extract and 100 g L -1 Ca +2 ; mixed solution with 15 g L -1 L-glutamic acid, and 15 g L -1 extract, and 100 g L -1 Ca +2 . The solutions were diluted in water at 3 ml L -1 concentration, and have been sprayed over the plants, on 12, 28 and 42 days after the emergence. Biometrical parameters were evaluated during plants growth, and at the end, the grain production was quantified. Data analysis has shown the effect of solutions in plants growth and grain production, characterizing the biostimulant effect of the mixed solution with 30 g L -1 extract and 100 g L -1 Ca +2 , and the mixed solution with 15 g L -1 L-glutamic acid, and 15 g L -1 extract, and 100 g L -1 Ca +2 .

Growth evaluation of Oreochromis niloticus (Cichlidae, Neopterygii) exposed to Trichlorfon

Abstract: The aim of this work was to evaluate the influence of Trichlorfon on the growth of cultured fishes. Using Oreochromis niloticus as fish model, bioassays were performed in the laboratory and field. Biometry was performed for 16 weeks. The treatment started after the sixth week of biometry, with the application of five weekly doses of 0.25 ppm of Trichlorfon. Growth data were compared by longitudinal analyses. In the laboratory, the treated fishes showed a reduction of growth; however, the statistical significance was only seen in the variable weight. In the field, the growth of treated fish was higher than that of the controls. This suggested that the treatment should be done in tanks with lower relative biomass to maintain the good zootechnic characteristics of fishes.

Estudo anatômico comparativo da casca do caule do araçá-amarelo e araçá-vermelho, Psidium cattleianum Sabine, Myrtaceae

Abstract: – (Comparative anatomy study of stem bark of yellow strawberry-guava and red strawberry-guava, Psidium cattleianum Sabine, Myrtaceae). Psidium cattleianum , known as yellow strawberry-guava and red strawberry-guava, belongs to the Myrtaceaefamily. This family has many taxonomy problems, and for this reason, is considered one of most complicated the identification of theirspecies. With the intention to clarify these difficulties, some alternative studies are being developed, such as the anatomy of bark, toolthat contributes to the understanding of taxonomic problems; however, it is a tool currently few explored. In the present study, thestructure of the stem bark of yellow strawberry-guava and red strawberry-guava was analyzed and compared, in order to verify thehypothesis of two taxons for P. cattleianum . For in such a way , samples of three individuals of each morphotypes had been collected andprocessed in agreement of procedure indicated for structural analyzes. The differences between the morphotypes can be observed inperiderm, in the arrangement of parenchymatics cells and, in general way , in the or ganization of the collapsed phloem. The results gottenin this research showed that the morphotypes of

Aprendizagem tecnológica e a teoria da hélice tripla: estudo de caso num apl de louças

Abstract: The promotion of productive agglomerations can be a form to create learning spaces. The local development through f the interaction among universities, companies and government has been the shortest way for technological learning and innovation. This article has the objective to identify the mechanisms of technological learning, driven by the interaction between the agents who form the productive cluster of dinnerware in Campo Largo - Parana. This cluster is responsible for 90% of the national production, generating approximately 4,000 direct and indirect jobs in the State. The theoretical framework is given by the Triple Helix model, developed by Etzkowitz and Leydesdorff (1997). It evaluates the technological innovation as resulted of the interaction between the agents: government, companies and university. The research was carried by means of a case study evolving a collection of the data in fifteen companies. It is identified some actions that already are presenting results, as it is the case of a project of “glue under pressure” and the celebration of the international agreement to the construction of a technological center of ceramics. The research also detaches the necessity of governance mechanisms between the stakeholders the cluster.

A interação dos relacionamentos com os recursos e a legitimidade no processo de criação de uma organização social

Abstract: Studies on entrepreneurship are usually fragmented, with several focuses of analysis and different epistemological and ontological foundations However, efforts already exist on the part of some authors in analyzing such phenomenon through a more integrated perspective The objective of the present study is to analyze how the founders of Alianca Empreendedora (a non-governmental organization) used their relationship network to get resources and legitimacy for the creation of the referred organization Three theoretical approaches were adopted: relationship networks, vision based on resources and legitimacy The strategy of case study was adopted and a triangulation of several sources of evidences was made in order to understand the interaction between the relationship networks and the resources, as well as the legitimacy in the process of creation of this social organization Consistency between the theoretical approaches adopted in the study was reached, which has led to the reflection about the necessity of focusing not only the entrepreneur in order to comprehend the creation of new business, but also the context

ISO 14001: implementar ou não? Uma proposta para a tomada de decisão

Abstract: One of the difficulties of the decision making process, is that many entrepreneurs may find themselves incapable of finding enough subsidies for the decision of adopting or not the ISO 14001 standard. This work presents a tool that facilitates corporate decision making, providing a thorough analysis of the real necessity and feasibility of the implementation of the ISO 14001 standard and its certification. This tool consists of a multicriterial analysis, in which is possible to verify the compatibility between the organizational profile and the ISO 14001 standard. This recommendation of adopting or not the ISO 14001 standard seeks to facilitate the organization decision making; and, as a result, it also enhances the probability of the organization attaining its objectives. This tool presented a strong applicability when implemented in two companies.

Análise do perfil facial masculino adulto jovem, esteticamente agradável, em fotografias padronizadas: comparação da medição manual com a computadorizada

Abstract: Aim: To analyze the young male adult facial profile using standardized photographs and compare manual measuring procedures to the measuring procedures with the software Cef X (CDT). METHODS: The sample consisted of 40 Brazilian Caucasian individuals, with an average age of 21.9 years, who possessed pleasant profiles, normal occlusion, and no history of previous orthodontic treatment. Colored photographs measuring 10cm x 15cm were taken in a standard way with the subject in natural head position. The photographs were measured manually, using dial caliper and a protractor, as well as using the Cef X (CDT) computer program. Thirty six facial variables were analyzed with linear, angular, and proportional measurements. RESULTS: Manual and computerized measurement scores presented different statistics to 24 variables. In the computerized method only one measurement showed significant difference between the first and the second measuring whereas in the manual method eight measurements presented differences. CONCLUSION: Considering that there were differences in manual and computerized measurements, one must use respective mean values for each type of measuring procedure. Both types of measurement are reliable although the computerized one is more accurate. Due to the convenience and swiftness of the computerized measuring, it is best recommended.

Technical evaluation of serological screening tests for anti-Toxoplasma gondii antibodies to prevent unnecessary transfusion risks

Abstract: Serological assays to detect anti-Toxoplasma gondii antibodies and specific anamnesis associated with this highly prevalent infection could be necessary in hemotherapy services in order to regulate safer blood supplies thus avoiding unnecessary transfusion risks. Even though, such policies are not yet implemented. In order to evaluate this requirement, our research group designed a questionnaire filled up by 132 volunteer blood donors from Parana Hemotherapy Center (Hemepar) assessing the possible risk factors to toxoplasmic infection. A total of 20 IgG anti-Toxoplasma serological tests were done to check out for positive-reactivity. 60% of the selected serum samples reacted positively; from these, 50% reported having pets (average of 2 animals per person) and 33% of these pets were "semi-free". It suggested the probability of toxoplasmic infection through these animals. Only 2.2% of the interviewed individuals were aware of the correct concept of the disease and only 17% of them were actually approached by the Blood Center concerning the epidemiological importance of this disease. The current procedures established during blood transfusions are not entirely safe when associated to toxoplasmosis. Today there are no rules that standardize a seroscreening protocol, nor preventive measures for this disease related to hemotherapy services in Brazil, as well as in other services worldwide.

Análise do pH, acidez e açúcares totais de sucos de frutas industrializados

Abstract: O objetivo deste trabalho foi avaliar 20 sucos de frutas industrializados, sob o ponto de vista do potencial erosivo e cariogenico. Avaliaram-se tres parâmetros que podem contribuir para a possivel perda de minerais dentarios: concentracao de ions de hidrogenio (pH), acidez titulavel e carboidratos totais. O pH foi determinado com auxilio de um potenciometro Metler Toledo 320 previamente calibrado. A acidez foi determinada por titulometria, gotejando-se NaOH 0,1 N em amostras de cada suco ate que o pH das mesmas atingisse 7,0. Os carboidratos totais foram determinados pelo metodo do fenol-sulfurico. Todos os sucos analisados apresentaram pH inferior a 5,5, sendo que cinco apresentaram pH abaixo de 4,0. Ja os valores percentuais de acidez titulavel obtidos variaram entre 1,9 e 10,4 %. Onze dos sucos analisados apresentaram mais de 30% de acucares totais. Quando pH, acidez e acucares totais foram analisados em conjunto, percebese que a maioria dos sucos apresentou baixo pH, altas quantidades de carboidratos e elevada acidez, o que os tornam tanto erosivos quanto cariogenicos. Os resultados permitem sugerir que, se consumidos com frequencia, estes sucos podem contribuir para o desenvolvimento de erosao e carie dentaria. Descritores: Refrescos. pH. Erosao dentaria.

Análise da eficácia da cirurgia bariátrica na redução de peso corporal e no combate à obesidade mórbida

Abstract: O objetivo do presente estudo e analisar a eficacia da cirurgia bariatrica na reducao de peso corporal e no combate a obesidade morbida. A metodologia utilizada foi o levantamento bibliografico em tres livros e nas bases de dados Medline, Scielo e Lilacs, sendo selecionados 64 artigos, a partir do ano de 1992. Segundo a OMS (Organizacao Mundial de Saude), classifica-se a obesidade considerando-se o IMC (Indice de Massa Corporal) e baseando-se nos riscos de mortalidade independente do genero e idade. A abordagem clinica (reeducacao alimentar, atividade fisica e medicamentos) geralmente e ineficaz e, por isso, a cirurgia bariatrica e uma opcao de tratamento. Sao candidatos para o tratamento cirurgico os pacientes com IMC maior que 40 kg/m2 ou maior/igual a 35kg/m2 com comorbidades associadas. Existem tres tipos de tecnicas cirurgicas: as restritivas, as disabsortivas e as mistas. Pesquisas de campo envolvendo cirurgia bariatrica e reducao de peso corporal mostram que a maior parte da populacao a realizar cirurgia tem entre 37,9 e 39,7 anos; a tecnica cirurgia mais utilizada e gastroplastia com bypass gastrojejunal distal (tipo Fobi-Capella); o periodo medio de acompanhamento de pacientes operados e de 1 a 2 ano pos intervencao cirurgica; e, quanto a perda de peso corporal como efeito da cirurgia bariatrica, foi observada em todos os estudos. A conclusao da cirurgia, entretanto, nao finaliza o tratamento da obesidade. Pelo contrario, e o inicio de um periodo de 1 a 2 anos de mudancas comportamentais, alimentares e de exercicios fisicos.

O perfil do empreendedorismo nos países latino-americanos na perspectiva da capacidade de inovaçao

Abstract: O objetivo deste trabalho e analisar o perfil do empreendedor nos paises latino-americanos na perspectiva da inovacao. Utiliza-se, como referencial teorico, o conceito adotado pela Pesquisa Global Entrepreneurship Monitor – GEM sobre o empreendedor e o potencial de inovacao dos empreendimentos a partir da analise de tres variaveis, a saber: conhecimento do produto pelo mercado, numero de concorrentes e idade das tecnologias e processos. O levantamento dos dados desta pesquisa foi possivel por meio do intercâmbio entre os parceiros consorciados do GEM. Os resultados mostram que, apesar da America Latina ser uma das regioes mais empreendedoras, as idiossincrasias sociais e economicas e politicas locais geram resultados diferentes para os paises analisados. Os que possuem o maior potencial de inovacao mostram elevadas taxas de escolaridade, o que traz, como insights iniciais, a relevância da escolaridade para desenvolver este perfil que, na maioria das vezes, esta associado ao empreendedorismo por oportunidade ou voluntario.

Estado e expansão do ensino superior privado no Brasil: uma análise institucional dos anos de 1990

Abstract: Este artigo trata da expansao do ensino superior privado no Brasil, durante os anos de 1990, tendo como base as mudancas institucionais que envolveram o Estado no seculo XX, destacando sua crise nos anos de 1980, que culminaram na busca de um novo modelo na ultima decada analisada. Merece ser enfatizado que ainda nao ha clareza das relacoes Estado e Sociedade, mesmo em meados do seculo XXI, posto que possui menor numero de instrumentos de acao direta, nao obteve reducao significativa em seu tamanho, apresenta dificuldades nas operacoes regulatorias, mas mantem razoavel interesse em se constituir como Estado de Bem-Estar. Nesse contexto, torna-se mais facil o entendimento da expansao em voga, na medida em que se trata de um aspecto da mudanca e nao de um fenomeno isolado. Quanto a metodologia, foram realizadas 32 entrevistas semiestruturadas e analise autores que abordaram o assunto, cujas principais conclusoes estao apresentadas no final do texto.

As condições sociais de produção das lembranças entre imigrantes ucranianos

Abstract: This article seeks to put into focus the study of the relationship between "memory" and social belonging. Beginning with a critique of the objectives and tools advanced in Maurice Halbwachs's writings on "collective memory", the article embarks on a discussion of the social conditions that inflect upon the production of memories among people linked to a given social configuration. The empirical bases for the analysis are the recollections produced by peasant immigrants of Slavic origin - the "Rusyns" or "Ukrainians" - concerning their journey to Brazil in the end of the nineteenth century. The article starts with a critical study of Halbwachs's ideas on the relationship between "memory" and "society", and, after a brief presentation of the Ukrainian immigrants, explores the stories concerning their migrations in order to discuss the social mechanisms that impress upon their recollections meanings that both converge or diverge amongst themselves. It concludes by an examination of some of the implications of the analysis.

Desenvolvimento e Institucionalização de Práticas em Espaços Sócio-Territoriais: a Região dos Campos Gerais

Abstract: O objetivo do presente estudo foi verificar o processo de adocao da pratica organizacional do plantio direto e a simultânea descontinuidade da tecnologia do plantio convencional na Regiao dos Campos Gerais, Estado do Parana, Brasil, no periodo de 1970 a 2005. A perspectiva institucional de analise orientou o desenvolvimento da pesquisa, com destaque para a nocao de recorrencia entre estrutura e acao no processo de construcao social da realidade. O delineamento de pesquisa foi do tipo metodo misto, com uso de recortes seccionais e avaliacao longitudinal. Nesse sentido, destacamos tres fases de coleta e analise de dados: as duas primeiras, qualitativas, e a terceira, quantitativa. Em termos de resultado mais significativo, verificamos a predominância do comportamento de conformidade das organizacoes rurais as pressoes ambientais identificadas, o que sustentou o processo de substituicao da pratica do plantio convencional pela tecnologia do plantio direto. A conclusao do estudo aponta para relacoes de recorrencia e de simultaneidade entre pressoes ambientais e respostas estrategicas. Ou seja, as pressoes ambientais deixam de ser visualizadas, linear e sequencialmente, como variaveis ou eventos desencadeadores de mudancas para serem entendidas, fundamentalmente, como um conjunto de variaveis ou eventos que pode culminar em mudanca, desde que seja interpretado pelos atores sociais como relevante nessa direcao. Em suma, o que se constatou, efetivamente, foi a ocorrencia de um processo de causa-acao circular recursivo, no qual a dualidade entre persistencia e mudanca constitui componente central da dinâmica social.

E-mail survey with an attached Form: an off-line data collection alternative via the internet

Abstract: As people start incorporating the Internet in their daily routine, using its resources to carry out their usual activities, it becomes easier to use the Web's environment also to collect data by means of electronic surveys. This paper reports the use of a quantitative research survey, which used an "intelligent" MS Word form, which was sent through e-mail to industrial manufacturers in the state of Sao Paulo - Brazil. The response speed was much better than usually achieved using the conventional procedure of sending the survey through regular mail. The return rate was satisfactory and the cost was much lower than usually incurred, due to the virtualization of the contact with the respondent. The initiative was so successful that the authors decided to share their experience with the academic community, contributing to the maturing of the e-mail survey methodology. Although the focus of this study was strictly academic, the authors believe that the adopted procedures are also suitable for market research, feedback gathering and other entrepreneurial needs.

Education and pattern behavior on corneal donation

Abstract: OBJETIVO: Confrontar informacoes obtidas sobre doacao de corneas atraves de questionarios aplicados antes e apos a realizacao de um ciclo de palestras informativas aos profissionais da area de saude. Verificar o grau de conhecimento destes profissionais de hospital universitario em relacao a informacoes basicas sobre o transplante de cornea. Documentar a reacao pessoal destas pessoas frente ao procedimento. METODOS: Foi realizada uma campanha atraves de aulas com material audio visual especifico trazendo informacoes detalhadas sobre o processo de doacao e transplante de corneas. Estas palestras foram direcionadas a 115 profissionais da area de saude: 46 medicos e 69 academicos de medicina. Para a avaliacao foi elaborado um questionario, aplicado antes e depois das aulas com intervalo de 1 mes, composto de 7 perguntas referentes ao procedimento do transplante em si, e 3 perguntas direcionadas a posicao pessoal do medico em relacao a doacao de corneas. RESULTADOS: Inicialmente obteve-se 61,72% de acertos nas perguntas objetivas, aumentando para 77,70% apos o acesso as palestras. Nas perguntas subjetivas a porcentagem de profissionais que doariam suas corneas foi 91,5%, subindo para 93% apos as aulas. De forma semelhante o numero que autorizaria a doacao de cornea de um familiar aumentou de 91,5% para 94,4%. Quando questionados se ja haviam abordado uma familia espontâneamente e solicitado o procedimento de doacao de corneas a resposta foi positiva em 4,8% dos profissionais avaliados, e esta porcentagem subiu apenas para 5,5% apos a realizacao das palestras. CONCLUSAO: O despreparo dos profissionais de saude em relacao aos varios aspectos que concernem o transplante de corneas e nitido. Iniciativas isoladas como palestras informativas, apesar de necessarias, nao sao suficientes para mudar esta realidade.

Complex odontoma associated to a primary maxillary canine: case report Odontoma complexo associado ao canino decíduo superior: relato de caso

Abstract: Introduction: Odontomas are malformations of the dental tissues and may interfere with the eruption of the associated tooth. The early diagnosis, followed by a proper treatment at the right time, will result in a favorable prognosis and a desirable occlusion development. Complex odontomas associated to primary teeth are rare. Case report and conclusion: This article describes a case of a complex odontoma in a four-year-old girl that prevented eruption of the left primary canine. The treatment choice was enucleation of the odontoma and the maintenance of the left primary canine. In this case, complete removal of the complex odontoma was successfully conducted, since after one year of follow-up the primary maxillary canine restarted its eruption process.
