Effects of the medicinal plants Curcuma zedoaria and Camellia sinensis on halitosis controlAbstract: Volatile sulphur compounds (VSC) are the gases mainly responsible for halitosis (bad breath). The aim of this research was to evaluate the effects of medicinal plants on halitosis control. Two commonly used plants were tested: Curcuma zedoaria and Camellia sinensis (green tea). These plants were prepared as an aqueous solution and used as mouthwashes, compared with a standard mouthwash of 0.12% chlorhexidine gluconate and a placebo (water). The experiment was conducted with 30 volunteers from the School of Dentistry of São Jose dos Campos, Univ. Estadual Paulista -UNESP, SP, Brazil. Each volunteer tested the four mouthwashes. The Cysteine Challenge Method, modified for this study, was used for initial breath standardization. Four breath assessments were conducted after volunteers rinsed orally with acetylcysteine: one before the test mouthwash was used; the second, one minute after its use; a third 90 minutes later; and the last 180 minutes later. The results showed that chlorhexidine gluconate lowered VSC production immediately, and that this effect lasted up to 3 hours, while the tested plants had immediate inhibitory effects but no residual inhibitory effects on VSC. We concluded that Curcuma zedoaria and Camellia sinensis, prepared as infusions and used as mouthwashes, did not have a residual neutralizing effect on VSC.

RESUMO Objetivo: Foi realizado um estudo descritivo do tipo inquérito populacional com idosos diabéticos do programa de saúde da família de uma unidade básica de saúde (UBS) com o objetivo de estudar seu perfil sócio-demográfico e de saúde. Material e Métodos: Sexo, idade, escolaridade, estado civil, tempo de diagnóstico da diabetes, estado cognitivo e auditivo, comorbidades e capacidade funcional pelo Health Assessment Questionnaire (HAQ) foram coletados por meio de entrevista. Testes t de Student e Mann-Whitney foram utilizados adotando-se nível de significância á=5%. Resultados: Foram avaliados 154 idosos diabéticos com idade de 70,96 ± 7,20 anos (68,8% do sexo feminino), tempo de estudo entre quatro a sete anos (48,7%) e tempo de diagnóstico entre 10 a 20 anos (30,6%). Foram encontrados percentuais elevados de comorbidades (hipertensão arterial-81,3%) e a maioria era funcionalmente independente pelo HAQ (72%). Conclusões: O aumento do contingente de idosos e a maior prevalência de doenças crônicas como a diabetes e suas comorbidades/incapacidades impõem a necessidade de rediscutir a atenção à saúde na unidade básica estudada, visando a implementação de ações promocionais interdisciplinares e, sobretudo, a orientação de idosos, seus cuidadores e familiares no processo de autocuidado e na perspectiva da manutenção da autonomia e independência.

BackgroundOdontogenic tumors are lesions that are derived from remnants of the components of the developing tooth germ. The calcifying cystic odontogenic tumor or calcifying odontogenic cyst is a benign cystic neoplasm of odontogenic origin that is characterized by an ameloblastoma-like epithelium and ghost cells. Calcifying cystic odontogenic tumor may be centrally or peripherally located, and its ghost cells may exhibit calcification, as first described by Gorlin in 1962. Most peripheral calcifying cystic odontogenic tumors are located in the anterior gingiva of the mandible or maxilla.Case presentationAuthors report a rare case of a peripheral calcifying cystic odontogenic tumor of the maxillary gingiva. A 39-year-old male patient presented with a fibrous mass on the attached buccal gingiva of the upper left cuspid teeth. It was 0.7-cm-diameter, painless and it was clinically diagnosed as a peripheral ossifying fibroma. After an excisional biopsy, the diagnosis was peripheric calcifying cystic odontogenic tumor. The patient was monitored for five years following the excision, and no recurrence was detected.ConclusionsAll biopsy material must be sent for histological examination. If the histological examination of gingival lesions with innocuous appearance is not performed, the frequency of peripheral calcifying cystic odontogenic tumor and other peripheral odontogenic tumors may be underestimated.

RESUMOObjetivos: Avaliar o ambiente de trabalho de um restaurante comercial do ponto de vista ergonômico em relação a seus aspectos ambientais e físicos, bem como o estado nutricional e a que condições de trabalho estão expostos os funcionários. Metodologia: Estudo transversal e observacional realizado entre fevereiro e maio de 2016, em uma unidade de alimentação e nutrição da zona urbana de São Paulo, sendo analisados 30 funcionários. Foram avaliados os níveis de ruídos, luminosidade, temperatura, além de estado nutricional, uso de equipamentos de proteção, carregamento de peso, atividades repetitivas e áreas do corpo que mais geram dor ou desconforto. Resultados: Foram encontrados níveis de ruídos e temperatura adequados às atividades desenvolvidas, o que não ocorreu com a iluminação. Foi observado um alto índice de sobrepeso e obesidade e metade dos funcionários relatou carregar peso e realizar movimentos repetitivos, refletindo a possibilidade de lesões, sendo que as áreas que mais geram desconforto são pernas (33,3%), ombros (30,0%) e tornozelo (23,3%), cujas dores são intensificadas pela jornada normal de trabalho. Conclusão: Observou-se a necessidade de treinamentos específicos e adequação do ambiente de trabalho às necessidades do trabalhador para a prevenção de riscos ergonômicos e melhoria do desempenho dos funcionários.

An integrated optimization workflow was developed to characterize seismic and sub-seismic fault networks from history-matching. A fractal model of fault networks is optimized via the gradual deformation of stochastic realizations of fault density maps, fault spatial and length distributions. In order to facilitate the history-matching, connectivity analysis tools were developed for characterizing wells-reservoir and well-to-well connectivity. Indeed these connectivity properties usually depend on the fault network realization and may be strongly correlated with the reservoir flow dynamics. Connectivity analyses were performed on a fractured reservoir model involving a five-spot well configuration with four injectors and one producer. The connectivity was estimated from shortest path algorithms applied on a graph representation of the reservoir model. Several reservoir simulations were performed for different fault network realizations to seek correlations between injector-producer connectivity and water breakthrough time. The impact of the fracture properties uncertainties on the wells-reservoir connectivity was estimated via the cumulated connected volume computed for each well. This connectivity measure provides a mean to characterize and classify fault network realizations. Correlations were found between the water breakthrough time and the injector-producer connectivity, thus allowing one to identify the most probable fault network realizations to match the observed water breakthrough time. Finally, for a given fault network realization, it is shown how the oil recovery can be optimized by correlating injectors rates with the injector-producer connectivity. A gain of 3.106 m3 in produced oil was obtained, while retarding the water breakthrough time by 16 years, compared with a case where all injectors have the same rate. The proposed methodology and tools facilitate the history-matching of fractured reservoir, providing consistent reservoir models that can be used for production forecast and optimization.
