Dentigerous cysts in primary dentition: Report of 2 cases

Dentigerous cysts are benign odontogenic cysts associated with the crowns of permanent teeth. They are usually single in occurrence and located in the mandible. The purpose of this case report was to describe the management of 2 dentigerous cysts in children. The treatments instituted were the extraction of the deciduous tooth involved followed by marsupialization in the first case and enucleation in the second one. Both treatments allowed rapid healing of the lesion and eruption of the permanent teeth without the need for orthodontic treatment.

Babesia bovis infection in cattle in the southwestern Brazilian Amazon

The present study provides the first epidemiological data on infection with Babesia bovis in cattle raised in the southwestern Brazilian Amazon. Blood clot samples were filtered through nylon cloth before being submitted to DNA extraction. PCR and nested-PCR were applied to assess the frequency of infection with B. bovis in calves with ages from 4 to 12 months bred in 4 microregions each in the states of Rondônia and Acre. After the DNA was extracted from the samples, the infection in cattle was investigated by amplification of the rap1 gene from B. bovis. The DNA amplification results revealed a frequency of infection with B. bovis of 95.1% (272/286) in the samples from Rondônia and 96.1% (195/203) in those from Acre. The high frequency of B. bovis infection in the animals with ages from 4 to 12 months indicates a situation of enzootic stability in the regions studied. The infection rates are comparable to those detected by immunodiagnostic techniques in other endemic regions of Brazil. © 2012 Elsevier GmbH.

Aprendizado de máquina simbólico e técnicas fractais para caracterizar rejeição em biópsia miocárdica

This work combines symbolic machine learning and multiscale fractal techniques to generate models that characterize cellular rejection in myocardial biopsies and that can base a diagnosis support system. The models express the knowledge by the features threshold, fractal dimension, lacunarity, number of clusters, spatial percolation and percolation probability, all obtained with myocardial biopsies processing. Models were evaluated and the most significant was the one generated by the C4.5 algorithm for the features spatial percolation and number of clusters. The result is relevant and contributes to the specialized literature since it determines a standard diagnosis protocol. © 2013 Springer.

Desempenho motor de aluno com paralisia cerebral discinética frente à adaptação das propriedades físicas de recurso pedagógico

The main purpose of this study was to analyze the modified physical properties of an educational resource for facilitating the handling of a child with dyskinetic cerebral palsy. The participant of the study was a six year old child with dyskinetic cerebral palsy enrolled in a regular early childhood education classroom. The educational resource that was selected was a brick game, in which the physical properties of weight, size and texture had been modified. The analysis was made regarding the quality of upper limb movement to the variables: righting index, scalar displacement (s), average speed (As) and time (t). The results showed that combined large size and heavy weight did not have a satisfactory outcome, affecting both grasping the educational resource and fitting. There was also inconsistency in children with cerebral palsy's responses. There is variation in the results, though a standard cannot be established. Thus, this study contributed to understanding the motor responses of a child with dyskinetic cerebral palsy when participating in a fitting activity with educational resources in which the physical properties had been modified.

Population Parameters Based on Known Pedigree Records from Brazilian Jaffarabadi Buffaloes

The objective of this study was to evaluate the effective number of founders and ancestors, generation intervals and completeness of pedigree in Jaffarabadi breed buffaloes raised in Brazil. Pedigree records of 1,272 animals born from 1966 were used. The parameters were estimated using ENDOG, computational population genetic software. The obtained value for completeness of pedigree was 99.5, 50.9, and 20.5 for, the first, second and third generations, respectively. Generation interval estimates expressed in years and considering different pathways were 12.28 +/- 6.90 (sire-son), 11.55 +/- 6.07 (sire-daughter), 8.20 +/- 2.63 (dam-son) and 8.794 +/-.33 (dam-daughter). The overall average generation interval was 10.17 +/- 5.43 years. The number of founders, equivalent founders and ancestor animals that contributed for the genetic diversity in the reference population (1059) were 136, 130 and 134, respectively. Effective number of founder (f(e)=8) and ancestors (f(a)=7) were small, and the calculated expected inbreeding increase per generation was 4.99%. Four ancestors explained 50% of the genetic variability in the population and the major ancestor contributed with approximately 33% of the total population genetic variation. The genetic diversity within the current population is low as a consequence of a reduced number of ancestors.

A Bienal do Vazio: análise comparativa das estratégias de tomada de posição dos jornais O Estado de S. Paulo e Jornal Semanal da 28ª Bienal de São Paulo

This paper proposes a comparative analysis of cultural critical, articles and reports related to the 28th International Biennial of Art of São Paulo published in the newspapers O Estado de S. Paulo and Jornal Semanal da 28ª Bienal de São Paulo, from October to December 2008. Specific aims of analysis are how an institution devoted, like Biennial, creates mechanisms to defend their choices and hegemonic position within the arts field and also to examine how this dedication can be demystified by critics from diffusion field not linked to the institution. For the study will be used the concepts of field, hierarchy of legitimacy and position of an agent developed by Pierre Bourdieu, as well as historical notions of Cultural Journalism and journalistic criticism

Crenças, pressupostos e conhecimentos de professores em serviço sobre língua(gem) em um curso de formação continuada

O cenário atual de globalização e comunicação intercultural traz impacto significativo para a maneira como entendemos a relação entre língua e sociedade. Gera, também, para o ensino de línguas, a necessidade de o professor compreender suas crenças, pressupostos e conhecimentos (WOODS, 1996) em relação à língua que ensina, uma vez que ele é um importante agente na orquestração da interação de várias histórias de vida e horizontes de entendimento por meio de sua prática pedagógica. Neste artigo, apresentamos e discutimos os resultados de duas pesquisas de doutorado (SALOMÃO, 2012; MENEGHINI, 2013), conduzidas em um mesmo contexto de um curso híbrido (presencial/virtual) de formação continuada, em relação às crenças dos professores sobre as variedades geolinguísticas do espanhol. Ponderamos que a questão da escolha por uma variedade está muitas vezes relacionada às concepções estruturais de língua, assim como está imbricada por uma tessitura de fatores que demonstram falta de consciência das vozes das quais os professores se apropriam para justificar suas opções teórico-metodológicas. O desafio que se coloca para a formação de professores, então, nos parece ser o de auxiliá-los no desenvolvimento de consciência crítica, promovida pela reflexão sobre suas crenças sobre língua(gem), a partir de experiências que possam levá-los a (re)conhecer suas escolhas por determinada variedade linguística. Palavras-chave: Crenças de professores de línguas. Variedades linguísticas. Reflexão.

Comparação entre o Disease Activity Score-28 e o Juvenile Arthritis Disease Activity Score na artrite idiopática juvenil

Introduction: the assessment of the activity of rheumatoid arthritis and juvenile idiopathic arthritis is made by means of different tools, respectively DAS-28 and JADAS.Objective: To compare DAS-28 and JADAS with scores of 71, 27 and 10 joint counts in juvenile idiopathic arthritis.Method: A secondary analysis of a phase III placebo-controlled trial, testing safety and efficacy of abatacept was conducted in 8 patients with 178 assessment visits. Joint count scores for active and limited joints, physician's and parents'global assessment by 0-10 cm Visual Analog Scale, and erythrocyte sedimentation rate normalized to 0-10 scale, in all visits. The comparison among the activity indices in different observations was made through Anova or adjusted gamma model. The paired observations between DAS-28 and JADAS 71, 27 and 10, respectively, were analyzed by linear regression.Results: There were significant differences among individual measures, except for ESR, in the first four months of biological treatment, when five of the eight patients reached ACR-Pedi 30, with improvement. The indices of DAS-28, JADAS 71, 27 and 10 also showed significant difference during follow-up. Linear regression adjusted model between DAS-28 and JADAS resulted in mathematical formulas for conversion: [DAS-28 = 0.0709 (JADAS 71) + 1.267] (R-2 = 0.49); [DAS-28 = 0.084 (JADAS 27) + 1.7404] (R-2 = 0.47) and [DAS-28 = 0.1129 (JADAS-10) + 1.5748] (R-2 = 0.50).Conclusion: The conversion of scores of DAS-28 and JADAS 71, 27 and 10 for this mathematical model would allow equivalent application of both in adolescents with arthritis.
