Conservative Management of a Large Keratocystic Odontogenic Tumor in the Maxilla

Keratocystic odontogenic tumor is characterized by high recurrence rates. Conservative or aggressive management has been suggested as a method of treatment. Decompression is a conservative treatment that has been used in the treatment of large odontogenic cysts. The authors report a case of a 14-year-old patient with a keratocystic odontogenic tumor located in the right maxilla, which was treated by decompression followed by enucleation with curettage. The lesion did not recur on follow-up for 3 years after the enucleation surgery.

Conservative Approach: Using Decompression Procedure for Management of a Large Unicystic Ameloblastoma of the Mandible

Ameloblastoma is a relatively uncommon benign odontogenic tumor, which is locally aggressive and has a high tendency to recur, despite its benign histopathologic features. This pathology can be classified into 4 groups: unicystic, solid or multicystic, peripheral, and malignant. There are 3 variants of unicystic ameloblastoma, as luminal, intraluminal, and mural. Therefore, in mural ameloblastoma, the fibrous wall of the cyst is infiltrated with tumor nodules, and for this reason it is considered the most aggressive variant of unicystic ameloblastomas. Various treatment techniques for ameloblastomas have been proposed, which include decompression, enucleation/curettage, sclerotizing solution, cryosurgery, marginal resection, and aggressive resection. Literature shows treatment of this lesion continues to be a subject of intense interest and some controversy. Thus, the authors aimed to describe a case of a mural unicystic ameloblastoma of follicular subtype in a 19-year-old subject who was successfully treated using conservative approaches, as decompression. The patient has been followed up for 3 years, and has remained clinically and radiographically disease-free.

Using Conservative Condylectomy for Management of a Large Osteochondroma of the Mandibular Condyle With 6-Year Follow- up

Osteochondroma is a hamartomatous proliferation of cartilaginous tissue, which is the most common benign tumor of the long bones, but is relatively rare in the maxillofacial region. Most cases of mandibular condylar osteochondroma manifest with facial asymmetry or malocclusion with limited temporomandibular joint movements. Several approaches for management of this lesion have been proposed, as conservative condylectomy technique. This procedure has been suggested a valid approach to minimize facial asymmetry, contributing to the recovery of occlusion associated with no local tumor recurrence, and without condylar reconstruction procedure. Therefore, this article aims to describe a clinical report of a true osteochondroma of the mandibular condyle in a 35-year-old patient who was successfully treated using conservative condylectomy procedure.

A sewage sludge co-composting process using respirometric monitoring method in hermetic rotary reactor

This paper has the objective of monitoring the biological activity of composting process of sewage sludge, sugarcane bagasse and ground coffee in a hermetic rotary reactor using the respirometric method in laboratory scale, in order to obtain parameters and system design for large scale projects. Another particularity of this study is the use of a hermetic reactor with gas purging cycles. Purging was performed when the percentage of oxygen reached less than 5%, thus eliminating the gaseous mixture (with elevated CO2 ratio) and the introduction of environmental air with around 21% of O2, successively until the compost was stabilized. The average purge intervals obtained were 29 h and 2 min with reactor rotation frequency of 15 min. The time of the compost stabilization was optimized in 60% if compared to the 90 days in the traditional method. The results obtained can be used to design the process in industrial scale using a simple O2 gas analyzer.

Modelling an expert GIS system based on knowledge to evaluate oil spill environmental sensitivity

Oil spills cause great damage to coastal habitats, especially when rapid and suitable response measures are not taken. Establishing high priority areas is fundamental for the operation of response teams. Under this context and considering the need for keeping all geographical information up-to-date for emergencial use, the present study proposes employing a decision tree coupled with a knowledge-based approach using GIS to assign oil sensitivity indices to Brazilian coastal habitats. The modelled system works based on rules set by the official standards of Brazilian Federal Environment Organ. We tested it on one of the littoral regions of Brazil where transportation of petroleum is most intense: the coast of the municipalities of Sao Sebastiao and Caraguatatuba in the northern littoral of São Paulo state, Brazil. The system automatically ranked the littoral sensitivity index of the study area habitats according to geographical conditions during summer and winter; since index ranks of some habitats varied between these seasons because of sediment alterations. The obtained results illustrate the great potential of the proposed system in generating ESI maps and in aiding response teams during emergency operations. (C) 2009 Elsevier Ltd.

Autogenous transplantation of rib cartilage preserved in glycerol, after removal of the perichondrium, to the malar process of rats--a histological study (Part I).

Seventy-two male albino rats received autogenous transplants of glycerol-preserved rib cartilage into the malar process. The animals were divided into two groups which received preserved cartilage with or without perichondrium. The implants were well tolerated and removal of the perichondrium enhanced the rate of resorption and bone replacement of the material.

Ensino de gestão da capacidade e da empresa com o apoio do jogo Mercado Virtual no curso de Mestrado Integrado em Engenharia Industrial e Gestão da UMINHO/Azurém e no Programa de Pós-Graduação em Engenharia de Produção da FEB/Bauru/UNESP

O jogo de empresas Mercado Virtual foi desenvolvido para mediar o processo ensino-aprendizagem na área de tomada decisão e gestão de empresas e tem um banco de dados que armazena as decisões dos alunos. Os dados nele armazenados foram analisados em relação ao balanceamento de capacidade, objetivo de lucro e uso de recursos financeiros da empresa e foram encontradas incoerências entre os conteúdos pertinentes ao modelo e as decisões dos alunos. Elas foram classificadas como lacunas de aprendizado. Com o objetivo de analisar se as mesmas se repetem entre alunos do Programa de Mestrado Engenharia de Produção da UNESP de Bauru e Mestrado Integrado em Engenharia Industrial e Gestão da Uminho de Guimarães, Portugal, foram realizados dois experimentos, um em cada grupo. Para realizá-los utilizou-se o jogo Mercado Virtual e uma planilha de dimensionamento da empresa nos dois locais. A Sala de Estudos, os indicadores e o questionário de pesquisa da opinião foram utilizados somente em Portugal. Os resultados mostraram que o jogo é capaz de evidenciar as diferenças de domínio de conteúdo nos dois grupos e, também, que estas diferenças estão associadas aos projetos dos cursos. Sendo uma pesquisa exploratória, os experimentos foram realizados considerando-se somente os controles do jogo. Por isso, propõe-se a realização de pesquisas adicionais combinando controle sobre algumas das variáveis relacionadas do uso do jogo e atuação sobre aprendizagem dos alunos na forma de entrevistas e pesquisas não estruturadas. Conforme previsto, a pesquisa mostrou que os jogos podem ser utilizados com objetivos de aprendizagem mais amplos, considerando-se a avaliação indireta e cruzada sobre as decisões tomadas pelos alunos, como é o caso dos indicadores. Outra contribuição importante da pesquisa refere-se ao uso de jogos de empresas sob condições pouco controladas, ou seja, não houve...

Aplicação da técnica de grupo focal em pesquisa da Rede-SANS sobre as ações de alimentação e nutrição na atenção básica em saúde

Focus groups are seen as important tools in qualitative research for evaluating projects aimed at articulating social networks and movements. Six focus groups were held as one of the stages in research as part of the Food Safety and Sustainable Nutrition Project (SANS). This social network articulates the academic world with social movements and government in defense of the human right to suitable nutrition. This report is aimed at discussing the experience of applying focus groups to the investigation of perceptions by health professionals of activities related to food and nutrition in basic health care. These groups made it possible to bring together 52 professionals from 13 municipalities in the State of São Paulo, Brazil, and they exchanged experiences and debated issues related to food safety in the area of health care. The group discussions identified eating, nutrition vigilance and intersectoriality as emerging topics. The focus group technique proved to be a suitable tool for investigating the topic quickly and in depth, with a large number of professionals working in different contexts. In fact, the discussions went beyond the objectives of the research, since the group work made it possible to strengthen the process of articulation carried out by a network that promoting local measures in food safety and sustainable nutrition.
