No consensus exists concerning the best management for OKCs. More aggressive treatments (ostectomy, resection, or use of adjunctive therapies like Carnoy's solution and liquid nitrogen) can have many disadvantages and risks. Therefore, it is necessary to identify the conservative approach for OKCs that results in a lower recurrence rate.

Clinical and radiographic diagnoses associated with surgical exploration are the most important treatment options in order to avoid radical surgery or unnecessary endodontic treatment, mainly when idiopathic bone cavities are detected in children and adolescents. Further studies aimed at elucidating the etiopathogenesis of this condition and defining the most appropriate treatment should be conducted.

Objectives:This study approaches the history of reclassifications and redefinitions around the odontogenic keratocyst (OK), as proposed by the World Health Organization (WHO), and aims to understand the impact of those changes on the prevalence and epidemiology of odontogenic tumors (OTs).Methodology:Cases of OTs diagnosed in an Oral Pathology service between January 1996 and December 2016 were reviewed. Demographic data of patients such as age, gender and site of lesions were retrieved from their respective records.Results:Within the studied period, 7,805 microscopic reports were elaborated and 200 (2.56%) of these were diagnosed as OTs. Out of these 200, between 1996 and 2005, prior to the 2005 WHO classification, there were 41 (20.5%) OTs cases, being odontoma the most frequent (23; 56.09%), followed by ameloblastoma (8; 19.51%) and myxoma (03; 7.31%). Between 2006 and 2016, after the previous 2005 WHO classification there were 159 (79.5%) OTs, being odontogenic keratocystic tumor (KCOT) the most frequent (68; 42.76%), followed by odontoma (39; 24.52%) and ameloblastoma (21; 13.20%).Conclusions:As of today, the most recent WHO classification to be followed brings KCOT back to the cyst category, which will impact on the prevalence and epidemiology of OTs; thus, this study was able to identify a considerable increase (287.80%) in the prevalence of OTs when the 2005 WHO classification was utilized. Despite being an important academic exercise, classifying odontogenic lesions and determining whether to place the odontogenic keratocyst in a cyst or tumor category is crucial to establish the correct diagnosis and treatment to follow, whether by oral medicine or oral surgery specialist, or by the general practitioner.

Objective: to describe the perceptions of people with intestinal ostomies on changes related to nutritional and lifestyle aspects. Method: exploratory and descriptive study, with a qualitative approach, performed with 17 patients with intestinal ostomies, who participate in a group of ostomized in a municipality in the countryside of Rio Grande do Sul (Brazil). Data were collected through semi-structured interviews. The data were analyzed based on the thematic analysis from which two categories emerged: “Change in the eating habits and nutritional profile of people with ostomy” and “living with the new”. Results: many changes that occur with the ostomized people, with body weight preferences and eating habits. There are daily situations that require adaptation to be experienced, among them: domestic tasks, sexuality, sports, work and leisure activities. The subjects who use the irrigation method presented autonomy in their daily life and see the ostomy as a new possibility in the face of the disease. Conclusion: to minimize the repercussions that occur in the lifestyle of ostomized people, there is evidence of the need for individualized nutritional and psychological follow-up and of extension in the guidelines of the professional teams that work with them, as well as the dissemination of the irrigation method to people with ostomies who are able to perform such procedure.

Os cursos de enfermagem vêm investindo em inovações no processo formativo, apostando em metodologias ativas e problematizadoras, que ofereçam ao acadêmico vivências na realidade social. Objetiva-se relatar a vivência de ensino-aprendizagem vinculada a um projeto ampliado de ensino, pesquisa e extensão fundamentado nas teorias de enfermagem. Trata-se de um relato de experiência desenvolvida a partir de uma atividade teórico-prática, realizada por meio de visitas semanais de docentes e discentes de enfermagem às famílias em condições sociais, ambientais e econômicas vulneráveis. Os resultados mostram uma pedagogia ativa, dialógica e interativa, capaz de fomentar redes solidárias de cooperação e a promoção de ambientes polissêmicos, favorecidos pelas reflexões dos problemas sociais emergentes. Assim, instigar o protagonismo e empreendedorismo social na formação, a partir das teorias de enfermagem, significa desenvolver um conhecimento capaz de dialogar e integrar os diferentes saberes, pelo desenvolvimento de práticas em consonância com o exercício da cidadania e transformação social.

Cyanocrylates have been widely used in the medical and dental fields for several years. In Dentistry, cyanoacrylates have been used for suturing, pulp capping, as retrofilling material in endodontic surgeries, and as cervical plug for pulpless teeth bleaching. The biocompatibility of these adhesives has been the topic of many researches and subcutaneous implantation is an effective methodology for these studies. The present study evaluated the biocompatibility of three different cyanoacrylate-based adhesives. Thirty-six Wistar rats were used, divided into four groups of 9 animals each: A (control) -distilled water, B -cyanoacrylate ester (Super Bonder), C -n-butyl-cyanoacrylate (Histoacryl) and D -alpha-cyanoacrylate (Three Bond). The materials were dispensed in sponges of polyvinyl chloride, the animals were incised and the sponges were inserted in the subcutaneous tissue and sutured. Each group was sub-divided according to the time of sacrifice of the animals: 7, 21 and 45 days. Subjective analysis of the histologic material showed that all groups presented some degree of irritability, but the inflammatory reaction decreased with the experimental time in all groups. Group D showed an inflammatory reaction which was closer to that of the control group and was considered to have good biocompatibility. Groups B and C were similar and presented more aggressive inflammatory reactions when compared to the control group. Based on the results, it was concluded that alpha-cyanoacrylate (Three Bond) was the most biocompatible adhesive because it caused the lowest levels of inflammation.

Oral paracoccidioidomycosis has a strong predilection for the gingiva, whereas patients with gingival lesions do not differ from patients lacking such involvement. Early diagnosis of gingival/oral lesions may prevent life-threatening complications of this mycosis.
