O processo de recanalização das veias dos membros inferiores, após um episódio de trombose venosa profunda aguda em pacientes anticoagulados com heparina e inibidores da vitamina K, faz parte da evolução natural da remodelagem do trombo venoso. Esse complexo processo de remodelagem envolve a adesão do trombo à parede da veia, à resposta inflamatória da parede do vaso, levando à organização e subsequente contração do trombo, à neovascularização e à lise espontânea de áreas no interior do trombo. A presença de fluxo arterial espontâneo em veias com trombose recanalizada tem sido descrita como secundária à neovascularização e se caracteriza pelo desenvolvimento de fluxo com padrão de fístulas arteriovenosas, identificadas por meio de mapeamento dúplex colorido. Nesta revisão, são discutidos alguns aspectos controversos da história natural da trombose venosa profunda, para uma melhor compreensão da sua evolução e do seu impacto sobre a doença venosa.

Background:It has been stated that mandibular overdentures are more satisfactory than conventional dentures, but problems relating to the use of retrospective ratings, lack of control group and sequential provision of treatment may compromise the findings.Objective:To establish a comparison between treatment with conventional complete dentures and implant-retained overdentures in elderly patients by conducting a literature review.Materials and methods:A search of English language peer-review literature was completed using Medline up to 2008 focusing on evidence-based research. Randomised clinical trials (RCTs) and longitudinal prospective studies were favoured in the review, using a general hierarchical classification. Articles that did not focus exclusively on the comparison of patient satisfaction between complete dentures and overdentures were excluded from further evaluation. The last search was conducted in February 2008. Key terms included quality of life, patient satisfaction, edentulism, complete denture and overdenture.Results:Among the 90 articles found in the initial search, 27 met the inclusion criteria. This included 18 RCTs and eight prospective and one cohort study. Most of the articles stated superiority of the mandibular implant-retained overdenture therapy over the conventional complete denture regarding patient satisfaction and quality of life.Conclusion:Even with implant treatment presenting higher patient satisfaction and improvement of quality of life, it was not possible to establish a direct comparison between the studies due to differences in adopted methodologies.

Introduction: Both Mineral Trioxide Aggregate (MTA) and Portland cement (PC) have been highlighted because of their favorable biological properties, with extensive applications in Endodontics, including the possibility of using into root canal filling. Objective: This article reviews literature related to MTA and PC comparing their physical, chemical and biological properties, as well as their indications. Literature review: Literature reports studies revealing the similarities between these materials’ properties, including both biocompatibility and bone repair induction. Moreover, there is the need for the development of a root canal sealer based on these materials (MTA and PC). Conclusion: MTA and CP show promissory perspective both in Dentistry and Endodontics.

Background: The adenocarcinoma of the appendix is a rare disease, generally identified as an acute appendicitis in the clinical presentation. Preoperative diagnosis is extremely difficult and uncommon. Objective: To present two cases of adenocarcinoma of the appendix, unique for presenting in early ages, and a complete literature review on this topic. Cases report: First case: a 24-year-old man submitted to appendectomy for acute inflammatory abdomen. Sent to hospital due to a histopathological diagnosis of mucinous adenocarcinoma of the appendix. Right hemicolectomy, epiploectomy, ganglion and partial abdominal wall resection were performed. The patient is now in chemotherapy. Second case: a 32-year-old man presented, during appendectomy, with vegetant lesion on the apex of the appendix. The histopathological study revealed the presence of adenocarcinoma of the appendix. Right hemicolectomy with ganglion resection was performed. The patient does not present signs of recurring disease. Conclusion: The macroscopic and clinical similarity between adenocarcinoma of the appendix and acute appendicitis makes it important to check out histopathological study results. The cases above reinforce this requirement, as the authors have found adenocarcinoma of the appendix in young patients.

This study aimed to gather the determinants and indicators of environmental innovations through a literature review on the topic. But before it was made a presentation of concepts and typology of eco-innovation, with different points of view. The determinant more found by most authors was regulation, followed by market factors, cost reductions and company image. To highlight these determinants were presented some cases studies, including evidence in Brazil. Due to the short bibliography and case studies, there are few indicators of environmental innovation found, highlighting the investment in environmental R&D and patents

The demand for aesthetic restorations has increased during the last years. Dental ceramics are a successful alternative for some cases because of aesthetics and biocompatibility. Therefore, the aim of this literature review was to present the factors necessary to fabricate all-ceramic restorations with aesthetics similar to natural dentition. A search of English-language peer-review literature was completed using MEDLINE database from 1975 to 2009 including the keywords "aesthetic," "metal-free crown," "all-ceramic," and "color." It was observed that several factors influence aesthetics of all-ceramic restorations. Color scale, light source during color evaluation, characteristic of core material, color of supporting tooth, presence of root post, and type of cement are clinical factors that may influence color of the restorations. Laboratorial factors as technique for ceramic condensation, thickness, temperature, and number of firing cycles also influence the result of these crowns. Although several clinical and laboratorial factors influence aesthetics of all-ceramic restorations, the aesthetic success and longevity of these restorations depend on the integration with surrounding periodontal tissue.
