Oral complaints in progressive systemic sclerosis : two cases report

Progressive systemic sclerosis is a chronic sclerotic disease which causes diffuse, increased deposition of extracellular matrix in connective tissue with vascular abnormalities, resulting in tissue hypoxia. Aesthetic and facial dysfunction are followed by important oral and facial manifestation of disturbances such as xerostomia, the lack of saliva in the mouth, and its associated complications. Most clinical manifestations begin with tongue rigidity. The facial skin changes and bone resorption of mandible angle are often reported. Other systemic changes include the involvement of internal organs which leads to serious complications as well as disorders in the cardiac muscle and Raynaud´s phenomenon. The objective of the this paper is to report two cases of systemic sclerosis in patients with oral and facial manifestations of the disease. A brief review of the literature, focusing on deontological alterations is also presented

Avaliação da presença, do posicionamento e da Rizogênese dos terceiros molares em pacientes adultos: um estudo radiográfico

Objetivo: Analisar a presença, a rizogênese e o posicionamento dos terceiros molares em pacientes adultos do Curso de Odontologia da Universidade de Fortaleza, através de radiografias panorâmicas. Materiais e Métodos: Realizou-se um estudo observacional do tipo transversal retrospectivo no período de 5 anos no qual foram analisados 705 prontuários. De acordo com os critérios de inclusão e exclusão, selecionou-se uma amostra de 371 radiografias, no qual foi preenchida uma ficha de dados, que continham as classificações de Pell & Gregory, Winter e Nolla. Resultados: Houve predileção pelo sexo feminino (p=0,181), sendo a maioria entre 33 e 38 anos. No sexo masculino, os terceiros molares superiores se mostraram mais presentes na posição B, posição vertical entre 18 e 44 anos, e horizontal entre 45 e 67 anos (p<0,001). Os dentes inferiores prevaleceram na posição A (p=0,007) e classe I (p<0,001), e houve maior prevalência de mesio angulares do que os superiores entre 21 e 62 anos (p<0,05). O estágio 10 de Nolla foi mais prevalente após os 23 anos (p<0,001). Já no sexo feminino, houve prevalência, nos superiores, da posição C entre 18 e 20 anos, A entre 21 e 44 anos e B entre 45 e 50 anos (p<0,001), verticais entre 18 e 50 anos e horizontais acima dos 50 anos (p<0,001). Nos inferiores, houve prevalência da posição B entre 21 e 32 anos e A entre 38 e 56 anos (p=0,001), verticais entre 21 e 56 anos e mesio angular acima dos 57 anos (p=0,018). O estágio 10 de Nolla foi prevalente após os 24 anos (p<0,001). Conclusão: Há uma variação na presença dos terceiros molares em relação ao sexo e idade dos pacientes, além da diferença nas classificações citadas, trazendo repercussão nas dificuldades cirúrgicas

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Educomunicação e suas áreas de intervenção: Novos paradigmas para o diálogo intercultural

oai:omp.abpeducom.org.br:publicationFormat/1O material aqui divulgado representa, em essência, a contribuição do VII Encontro Brasileiro de Educomunicação ao V Global MIL Week, da UNESCO, ocorrido na ECA/USP, entre 3 e 5 de novembro de 2016. Estamos diante de um conjunto de 104 papers executivos, com uma média de entre 7 e 10 páginas, cada um. Com este rico e abundante material, chegamos ao sétimo e-book publicado pela ABPEducom, em seus seis primeiros anos de existência. A especificidade desta obra é a de trazer as “Áreas de Intervenção” do campo da Educomunicação, colocando-as a serviço de uma meta essencial ao agir educomunicativo: o diálogo intercultural, trabalhado na linha do tema geral do evento internacional: Media and Information Literacy: New Paradigms for Intercultural Dialogue

Changes in pharyngeal airway space and soft tissue after maxillary advancement and bimaxillary surgery

AIM:To evaluate changes in pharyngeal airway space (nasopharynx and oropharynx), soft palate and lingual vallecula after maxillary advancement surgery and maxillary advancement and mandibular setback surgery (bimaxillary surgery).METHODS:Twenty Class III adult patients were included in the study. Ten patients were treated with maxillary advancement and ten with bimaxillary surgery (maxillary advancement and mandibular setback). Cephalometric landmark measurements were recorded at 3 different time intervals: pre-surgical, post-surgical and six months after surgery. Data collected were subjected to one-way ANOVA (p<0.05).RESULTS: Nasopharyngeal airway space increased after maxillary advancement and decreased after bimaxillary surgery. There was increase in oropharyngeal dimensions in the region around the uvula and loss of space for lingual vallecula, while in Group 2 there was diminished space for both uvula and vallecula. The uvula and vallecula were moved forward in Group 1, whereas these structures were moved in the posterior direction in Group 2.CONCLUSIONS: After maxillary advancement surgery there was an increased in space in the nasopharyngeal region. The oropharyngeal region related to the uvula presented an increase in space, whereas there was a reduction in relation to the lingual vallecula. The uvula and lingual vallecula were moved forward. Bimaxillary surgery promoted a reduction in the nasopharyngeal and oropharyngeal regions as regards both the uvula and lingual vallecula. The uvula and lingual vallecula were moved in the posterior direction
