Resumo Introdução O protocolo de reabilitação com implantes dentários é uma opção de tratamento bem estabelecida para pacientes desdentados com alta taxa de sucesso. No entanto, existem fatores que podem levar à dificuldade de continuidade e até mesmo à perda completa da reabilitação. Microgaps são espaços encontrados entre o implante e o pilar protético que são causados pelo limite de precisão na fabricação do implante. Esse espaço pode causar micromovimentos e microinfiltração bacteriana que podem comprometer a vida útil do implante a longo prazo. Objetivo Medir e avaliar microgaps em implantes angulados e retos usando microscopia eletrônica de varredura. Para a realização do estudo, foram utilizados um total de 30 implantes osseointegrados SIN®, sendo 15 retos e 15 angulados. Material e método Para a análise comparativa desses componentes, foi utilizada a microscopia eletrônica de varredura, realizada por pesquisador devidamente calibrado e experiente. Resultado Observou-se que as medidas de microgaps de ambos os componentes estão de acordo com os valores clinicamente aceitáveis apresentados na literatura, porém os valores de microgaps dos componentes angulados foram consideravelmente maiores em comparação aos componentes retos. Conclusão Embora os valores apresentados corroborem os dados apresentados na literatura, estudos adicionais são necessários para uma compreensão mais abrangente e aprofundada da relação entre os microgaps dos componentes do sistema cone morse. sucesso entanto prazo varredura estudo 3 SIN SIN® 1 experiente Observouse Observou se literatura morse

Abstract Introduction The dental implant rehabilitation protocol is a well-established treatment option for edentulous patients with a high success rate. However, there are factors that can lead to difficulty in continuation and even complete loss of rehabilitation. Microgaps are spaces found between the implant and prosthetic abutment that are caused by the limit of precision in the manufacturing of the implant. This space can cause micromovements and bacterial microleakage that can compromise the long-term useful life of the implant. Objective Measure and evaluate microgaps in angled and straight implants using scanning electron microscopy. To carry out the study, a total of 30 SIN® osseointegrated implants were used, 15 of which were straight and 15 angled. Material and method For the comparative analysis of these components, scanning electron microscopy was used, carried out by a properly calibrated and experienced researcher. Result It was observed that the microgap measurements of both components are in accordance with the clinically acceptable values presented in the literature, however the microgap values of the angled components were considerably higher compared to the straight components. Conclusion Although the values presented corroborate the data presented in the literature, additional studies are necessary for a more comprehensive and in-depth understanding of the relationship between the microgaps of the morse cone system components. wellestablished well established rate However longterm long term study 3 SIN used 1 researcher literature indepth depth

RESUMO O carcinoma hepatocelular (CHC) é uma das principais causas de mortalidade relacionada a câncer no Brasil e no mundo. A Sociedade Brasileira de Hepatologia (SBH) publicou em 2015 suas primeiras recomendações sobre a abordagem do CHC. Desde então, novas evidências sobre o diagnóstico e tratamento do CHC foram relatadas na literatura médica, levando a diretoria da SBH a promover uma reunião monotemática sobre câncer primário de fígado em agosto de 2018 com o intuito de atualizar as recomendações sobre o manejo da neoplasia. Um grupo de experts foi convidado para realizar uma revisão sistemática da literatura e apresentar uma atualização baseada em evidências científicas visando que pudesse nortear a prática clínica multidisciplinar do CHC. O texto resultante foi submetido a avaliação e aprovação de todos membros da SBH através de sua homepage. O documento atual é a versão final que contêm as recomendações atualizadas e revisadas da SBH.

ABSTRACT Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related mortality worldwide. The Brazilian Society of Hepatology (SBH) published in 2015 its first recommendations about the management of HCC. Since then, new data have emerged in the literature, prompting the governing board of SBH to sponsor a single-topic meeting in August 2018 in São Paulo. All the invited experts were asked to make a systematic review of the literature reviewing the management of HCC in subjects with cirrhosis. After the meeting, all panelists gathered together for the discussion of the topics and the elaboration of updated recommendations. The text was subsequently submitted for suggestions and approval of all members of the Brazilian Society of Hepatology through its homepage. The present manuscript is the final version of the reviewed manuscript containing the recommendations of SBH.

ABSTRACT: Oral melanoma (OM) is an extremely rare and aggressive malignancy. A 67-year-old patient presented with complains of a slightly symptomatic spot in the mouth since the past 2 years. Extraoral examination revealed left cervical lymphadenopathy, and intraoral examination a blue-black multinodular sessile mass, with irregular margins, involving the attached gingiva of teeth 27 and 28, extending to vestibular sulcus and hard palate, measuring approximately 3.5 cm. The lesion presented focal areas of ulceration. Panoramic radiograph did not show bone involvement. The main diagnostic hypothesis was oral melanoma. Microscopic findings of the incisional biopsy revealed a proliferation of densely pigmented pleomorphic cells, invading the subepithelial connective tissue in sheets or nests showing an organoid pattern. Immunopositivity for S-100, Melan-A and HMB-45 confirmed the diagnosis of melanoma. The patient was referred to an oncology hospital in which multiple metastases were detected, and the patient was subjected to palliative care. Herein we report an OM in advanced clinical stage, and discuss the clinical, morphological and immunohistochemical diagnostic criteria with emphasis on the importance of early diagnosis.

RESUMEN: El melanoma oral (MO) es una malignidad extremadamente rara y agresiva. Un paciente de 67 años acudió a consulta con la queja de una mancha intraoral ligeramente sintomática, presente desde hace dos años. Al examen clínico extraoral, se encontró adenopatía cervical del lado izquierdo, y al examen intraoral, se observó una masa sésil multinodular de color negro azulado, focalmente ulcerada, con bordes irregulares, afectando la encía de los dientes 27 y 28, extendiéndose hasta el surco vestibular y el paladar duro, midiendo aproximadamente 3,5 cm. La radiografía panorámica no mostró involucramiento óseo. La principal hipótesis diagnóstica fue MO. Los hallazgos microscópicos de la biopsia incisional revelaron una proliferación de células pleomórficas densamente pigmentadas, invadiendo difusamente el tejido conectivo en forma de sábanas o nidos con patrón organoide. La positividad inmunohistoquímica para S-100, Melan-A y HMB-45 confirmó el diagnóstico de melanoma. El paciente fue referido a un hospital oncológico, en el cual se le detectaron múltiples metástasis y fue sometido a cuidados paliativos. Este es el reporte de un caso de MO diagnosticado en estado avanzado, en el que se discuten los criterios clínicos, morfológicos e inmunohistoquímicos para su diagnóstico, haciendo énfasis en la importancia del diagnóstico temprano.

RESUMO As doenças do fígado e das vias biliares são causas comuns de morbidade e mortalidade. Procedimentos invasivos com finalidade diagnóstica e terapêutica são frequentemente recomendados nos casos de doenças hepatobiliares. O reconhecimento das indicações e limitações das técnicas comumente empregadas é crucial para uma adequada seleção dos pacientes, maximizando os resultados positivos e reduzindo o risco de complicações. Em 2018, a Sociedade Brasileira de Hepatologia (SBH), em colaboração com a Sociedade Brasileira de Radiologia Intervencionista e Cirurgia Endovascular (SOBRICE) e a Sociedade Brasileira de Endoscopia Digestiva (SOBED) realizaram um encontro exclusivamente voltado para a discussão dos procedimentos invasivos nas doenças hepatobiliares. Este texto resume as principais recomendações discutidas durante o evento, e tem a intenção de auxiliar clínicos, gastroenterologistas, hepatologistas, radiologistas e endoscopistas no uso adequado dos procedimentos invasivos para manejo de pacientes com doenças hepatobiliares.

ABSTRACT Liver and biliary tract diseases are common causes of morbidity and mortality worldwide. Invasive procedures are usually performed in those patients with hepatobiliary diseases for both diagnostic and therapeutic purposes. Defining proper indications and restraints of commonly used techniques is crucial for proper patient selection, maximizing positive results and limiting complications. In 2018, the Brazilian Society of Hepatology (SBH) in cooperation with the Brazilian Society of Interventional Radiology and Endovascular surgery (SOBRICE) and the Brazilian Society of Digestive Endoscopy (SOBED) sponsored a joint single-topic meeting on invasive procedures in patients with hepatobiliary diseases. This paper summarizes the proceedings of the aforementioned meeting. It is intended to guide clinicians, gastroenterologists, hepatologists, radiologists, and endoscopists for the proper use of invasive procedures for management of patients with hepatobiliary diseases.
