The disease of multifactorial etiology develops because of the interaction of multiple genetic and environmental factors. The objective of this study was to investigate the profile of patients with oral cancer and to evaluate the influence of the factors related to the survival of these individuals in a high complexity Oncology unit of Feira de Santana, Bahia, Brazil, between 2010 and 2016. It is a hospital-based, retrospective cohort study where the population was composed of individuals with histopathological diagnosis of squamous cell carcinoma. Socio-demographic, life habits, lesion data, treatment, survival time and survival status variables were obtained by reviewing clinical records. Initially, a descriptive analysis of all variables was performed. Later, the Kaplan-Meier estimator was used to compute the survival probabilities at each time, with and without stratification. The log-rank test was used for the comparisons between the several curves. In order to estimate the effects of each variable on the survival of the individuals, the Cox models were adjusted for each of them and, from the significance of the relative risks at each time, the variables that entered the multivariable model were defined. The majority of cases occurred in male individuals, aged over 45 years, chronic smokers and alcoholics. Lesions predominantly localized in the tongue were diagnosed at an advanced stage of the disease. Surgical therapy associated with radiotherapy and chemotherapy was the most recommended for the young group and radiotherapy associated with chemotherapy for the old group. Results indicated that the only predictive factors for oral cancer were tumor staging and type of treatment, pointing out the need for strategies to reduce the main risk factors for the disease and the importance of early diagnosis, to increase the patients? survival and the improvement of their quality of life. / O c?ncer oral representa um grande problema de sa?de p?blica, com taxas de incid?ncia, mortalidade e sobrevida bastante vari?veis em todo o mundo. A doen?a de etiologia multifatorial desenvolve-se como resultado da intera??o de m?ltiplos fatores gen?ticos e ambientais. O objetivo deste estudo foi investigar o perfil de pacientes com c?ncer oral e avaliar a influ?ncia dos fatores relacionados ? sobrevida destes indiv?duos em uma unidade de alta complexidade em Oncologia de Feira de Santana, Bahia, no per?odo 2010 a 2016. Trata-se de um estudo de coorte retrospectivo, de base hospitalar, onde a popula??o foi composta por indiv?duos com diagn?stico histopatol?gico de carcinoma de c?lulas escamosas. Vari?veis sociodemogr?ficas, de h?bitos de vida, de dados da les?o, do tratamento, de tempo de sobrevida e de status de sobrevida foram obtidos atrav?s da revis?o de prontu?rios cl?nicos. Inicialmente foi realizada uma an?lise descritiva de todas as vari?veis. Posteriormente, para computar as probabilidades de sobrevida a cada tempo foi utilizado o estimador de Kaplan-Meier, sem e com estratifica??o. Para as compara??es entre as diversas curvas foi utilizado o teste de log-rank. Com o objetivo de estimar os efeitos de cada vari?vel na sobrevida dos indiv?duos, foram ajustados os modelos de Cox para cada uma delas e, a partir da signific?ncia dos riscos relativos a cada tempo, foram definidas quais entraram no modelo multivari?vel. A maioria dos casos ocorreu em indiv?duos do sexo masculino, com idade acima de 45 anos, tabagistas e etilistas cr?nicos. As les?es predominantemente localizadas em l?ngua foram diagnosticadas em est?gio avan?ado da doen?a. A terapia cir?rgica associada a radioterapia e quimioterapia foi a mais recomendada para o grupo jovem e a radioterapia associada a quimioterapia, para o grupo idoso. Os resultados indicaram que apenas o estadiamento do tumor e o tipo de tratamento foram fatores preditivos para o c?ncer oral, apontando a necessidade de estrat?gias para a redu??o dos principais fatores de risco para a doen?a e a import?ncia do diagn?stico precoce, com vistas ao aumento da sobrevida e ? melhoria da qualidade de vida dos pacientes.

O Cimento de Ion?mero de Vidro (CIV) ? o material eleito para selar as cavidades na t?cnica do ART devido ?s suas propriedades f?sicas, qu?micas e biol?gicas favor?veis. O objetivo do presente estudo foi comparar a performance cl?nica do Cimento de Ion?mero de Vidro (CIV) de alta viscosidade (Ketac Molar Easymix?3M? ESPE, Seefeld, Germany) com um CIV convencional de baixa viscosidade (Vidrion R?SS White, Rio de Janeiro, RJ, Brasil) acrescido de nanocristais de celulose (NC)- (CIVNC) em cavidades classe I de molares dec?duos usando a t?cnica do Tratamento Restaurador Atraum?tico (ART). Sessenta crian?as de 4 a 7 anos de idade, residentes na cidade de Diamantina- Minas Gerais, que apresentaram no m?nimo dois molares dec?duos com les?es de c?rie classe I em dentina foram inclu?das. Um ensaio cl?nico randomizado duplo cego foi realizado no qual os dois materiais (Ketac Molar e CIVNC) foram aleatoriamente inseridos nas cavidades, ap?s sorteios do dente a ser restaurado e do material a ser utilizado. A performance cl?nica das restaura??es foi avaliada ap?s 3 meses usando o crit?rio de Frencken. Considerou-se insucesso de uma restaura??o quando a mesma apresentava defeito marginal ?0,5 mm, desgaste gradual >0,5 mm, quando a restaura??o foi perdida ou substitu?da por outra e a extra??o do dente. A an?lise de sobrevida das restaura??es foi feita usando o teste Qui-quadrado com tend?ncia linear. Adotou-se o valor de p<0,05 como significativamente estat?stico. A taxa de sobrevida das restaura??es para o Ketac Molar foi de 96,7% e para o CIVNC 94,7%. Uma diferen?a estatisticamente significativa (p=0,034) foi observada entre os dois cimentos em rela??o ? presen?a de defeitos marginais menores que 0,5 mm encontrados em 18,3% dos dentes tratados com CIVNC e em 6,5% das restaura??es realizadas com Ketac Molar. A performance cl?nica de ambos os cimentos de ion?mero de vidro foi satisfat?ria ap?s tr?s meses. A maior diferen?a entre os dois materiais foi observada em defeitos marginais menores que 0,5 mm. / Disserta??o (Mestrado) ?

The glass ionomer cement (GIC) is the material chosen to seal the cavities at the ART approach due to their physical, chemical and biological favorable properties. The aim of this study was to compare the clinical performance of a high viscosity glass ionomer cement (GIC) (Ketac Molar Easymix/3M? ESPE, Seefeld, Germany) with a conventional low viscosity GIC (Vidrion R?SS White River de Janeiro, RJ, Brazil) added cellulose nanocrystals (NC)- (GICCN) in class I cavities of primary molars using the Atraumatic Restorative Treatment (ART) technique. Sixty children aged 4-7 years, residents in the city of Diamantina-Minas Gerais, who had at least two primary molars with carious lesions class I in dentin were included. A randomized double-blind clinical trial was conducted and the two materials (Ketac Molar and GICCN) were randomly inserted into the cavities, after raffles of the tooth to be restored and the material to be used. The clinical performance of the restorations was evaluated after 3 months using the criteria of Frencken. It was considered failure of a restoration when it presented a marginal defect ?0.5 mm, gradual wear >0.5 mm, when the restoration was lost or replaced by another treatment and the tooth extraction. Restorations survival analysis were made using the Chi-square test with linear trend. The value of p<0.05 was adopted as statistically significant. The survival rate of restorations for Ketac Molar was 96.7% and 94.7% for the GICCN. A statistically significant difference (p=0.034) was observed between the two cements in relation to the presence of marginal defects lower than 0.5 mm found in 18.3% of the treated teeth with the modified cement (GICCN) and in 6.5% of the restorations with Ketac Molar. The clinical performance of both glass ionomer cements was satisfactory after three months. Increased difference between the two materials was observed on marginal defects lower than 0.5 mm.

O presente estudo objetivou caracterizar o perfil cl?nico e epidemiol?gico dos pacientes que realizaram TCTH em um servi?o de refer?ncia no estado do Rio Grande do Norte (RN), estimar a sobrevida global dos transplantados e identificar as terapias que favorecem o aumento da sobrevida global. A primeira parte ocorreu junto ao servi?o de refer?ncia do estado do RN para realiza??o do TCTH. Trata de um estudo de abordagem quantitativa, do tipo coorte retrospectiva, descritivo e anal?tico, de base hospitalar que abordou 272 pacientes que realizaram TCTH. Os dados foram coletados no Servi?o de Arquivo M?dico e Estat?stica entre os meses de mar?o e setembro de 2016 por meio dos prontu?rios registrados entre os anos de 2008 e 2015, oito anos de execu??o do procedimento. Para a an?lise descritiva foi utilizado software livre estat?stico R vers?o 3.0.0 e para o c?lculo das probabilidades de sobrevida foi empregado o m?todo Kaplan-Meier por meio do Statistic Package for Social Sciences (SPSS) vers?o 22.0. Para o c?lculo da probabilidade de associa??o entre as caracter?sticas analisadas e os ?bitos foi utilizado o teste do Qui-quadrado de tend?ncia. A segunda parte do estudo se deu pela constru??o de uma Revis?o Sistem?tica (RS) da literatura sobre as terapias que favorecem o aumento a sobrevida de pacientes que realizaram o TCTH. O Protocolo de Pesquisa foi aprovado em seus aspectos ?ticos e metodol?gicos pelo Comit? de ?tica em Pesquisa da Universidade Federal do Rio Grande do Norte, com aprova??o em 01 de julho de 2015, sob o parecer no. 1.132.720 e CAAE no. 46202715.7.0000.5537. Dos 272 prontu?rios analisados houve predom?nio do sexo masculino 52,94%, com m?dia de 38,69 anos, 18,38% eram pardos e 47,06% casados. De acordo com as caracter?sticas cl?nicas, 23,16% apresentou como diagn?stico principal o Mieloma M?ltiplo, as toxicidades mais desenvolvidas foram as gastrointestinais (93,38%), todos os pacientes receberam tratamento por meio de antineopl?sticos, o TCTH realizado com maior frequ?ncia foi o alog?nico (54,78%), com c?lulas do sangue perif?rico (77,94%) e doador aparentado (71,81%). Cerca de 9% dos pacientes realizaram mais de um TCTH, 4,04% desenvolveu a Doen?a do Enxerto Contra Hospedeiro (DECH), dentre estes 54,55% apresentou o tipo cr?nico, a causa de morte mais registrada nas declara??es de ?bito foi o choque s?ptico (48,19%) e a sobrevida global dos pacientes transplantados foi de 4,03 meses, sem diferen?a estatisticamente significativa quando comparados os pacientes de acordo com o sexo (p=0,859). Quanto aos achados da RS n?o foi poss?vel identificar um consenso para definir a melhor forma de tratamento para o favorecimento do aumento da sobrevida global nos estudos revisados. A escolha da terap?utica adequada depender? especialmente das caracter?sticas cl?nicas apresentadas pelos indiv?duos. Entretanto, de forma geral, os planos terap?uticos utilizados pelo bra?o experimento dos ensaios cl?nicos analisados obtiveram melhores respostas para o aumento da sobrevida global dos indiv?duos testados. Portanto, conclui-se que h? a necessidade de realiza??o de outros estudos do tipo multic?ntricos que apresentem os perfis epidemiol?gicos e cl?nicos do TCTH no Brasil, haja vista que estes possibilitam a problematiza??o da realidade e a publica??o de evid?ncias confi?veis para atualiza??o dos conhecimentos cient?ficos. / Hematopoietic stem cell transplantation (HSCT) is used as a treatment strategy for a series of inherited or acquired malignant and non-malignant diseases, with the possibility of cure or increase in disease-free survival. The objective of this study was to characterize the clinical and epidemiological profile of the patients who underwent HSCT at a referral service in the state of Rio Grande do Norte (RN), to estimate the overall survival of transplant recipients and to identify therapies that favor increased overall survival. The first part occurred with the reference service of the state of the RN to perform the HSCT. This is a quantitative, retrospective, descriptive and analytical, hospital-based quantitative study that addressed 272 patients who underwent HSCT. The data were collected in the Medical Record and Statistic Service between March and September 2016 through medical records recorded between the years 2008 and 2015, eight years of execution of the procedure. For the descriptive analysis, statistical free software R version 3.0.0 was used and the Kaplan-Meier method was used to calculate survival probabilities using the Statistic Package for Social Sciences (SPSS) version 22.0. The trend chi-square test was used to calculate the probability of association between the characteristics analyzed and the deaths. The second part of the study was the construction of a Systematic Review (SR) of the literature on the therapies that favor the increase in the survival of patients who underwent HSCT. The Research Protocol was approved in its ethical and methodological aspects by the Research Ethics Committee of the Federal University of Rio Grande do Norte, with approval on July 1, 2015, under no. 1,132,720 and CAAE no. 46202715.7.0000.5537. Of the 272 patient charts analyzed, there was a predominance of males 52.94%, with a mean of 38.69 years, 18.38% were brown and 47.06% married. According to the clinical characteristics, 23.16% had as main diagnosis Multiple Myeloma, the most developed toxicities were gastrointestinal (93.38%), all patients received treatment with antineoplastics, the most frequently performed HSCT was (54.78%) with peripheral blood cells (77.94%) and related donor (71.81%). About 9% of the patients had more than one HSCT, 4.04% developed the Graft versus Host Disease (GVHD), of which 54.55% presented the chronic type, the most registered cause of death in the death certificates was Septic shock (48.19%) and overall survival of transplanted patients was 4.03 months, with no statistically significant difference when patients were compared according to sex (p = 0.859). Regarding the SR findings, it was not possible to identify a consensus to define the best form of treatment to favor the increase in overall survival in the reviewed studies. The choice of appropriate therapy will depend especially on the clinical characteristics presented by individuals. However, in general, the therapeutic plans used by the experimental arm of the analyzed clinical trials obtained better answers to increase the overall survival of the individuals tested. Therefore, it is concluded that there is a need to carry out other multicenter studies that present the epidemiological and clinical profiles of HSCT in Brazil, since these make it possible to problematize reality and to publish reliable evidence to update scientific knowledge.

A amostra do trabalho foi formada por indiv?duos de 60 anos ou mais pertencentes a 10 institui??es de longa perman?ncia para idosos (ILPI) da cidade do Natal/RN, sendo exclu?dos os hospitalizados ou em processo de cuidados paliativos. O Estudo 1 ? de tipo transversal (Outubro e Dezembro de 2013) e foi avaliada a IF mediante a escala de Katz e caracterizada quando houve limita??o em uma ou mais ABVD (alimenta??o, controle de esf?ncteres, transfer?ncias posturais, higiene pessoal, capacidade para se vestir e tomar banho). Como vari?veis independentes foram consideradas as sociodemogr?ficas, as relacionadas ? institui??o e ?s condi??es de sa?de. Usaram-se o teste qui-quadrado, teste de Fisher ou teste qui-quadrado de tend?ncia linear para a an?lise bivariada, assim como a regress?o log?stica para a multivariada. A amostra foi de 321 idosos e a preval?ncia de IF de 72,9% (IC 95%: 67,8-77,5%). A tarefa mais afetada foi o ?banho?, seguido por ?vestir-se? e ?ir ao banheiro?. O modelo final constatou associa??o com a institui??o de tipo privado (RP=1,33, p<0,001), idade igual ou superior a 83 anos (RP=1,26, p=0,003), ser institucionalizado por n?o ter cuidador (RP=1,17, p=0,033) e osteoporose (OR=1,23, p=0,045), ajustado por sexo. O Estudo 2 ? longitudinal de 24 meses de acompanhamento com intervalos de follow-up de 6 meses (5 ondas). Al?m dos crit?rios aplicados no Estudo 1, foram exclu?dos aqueles que apresentavam IF para todas as ABVD (banho, higiene pessoal, vestir-se, ir ao banheiro, caminhar, transfer?ncias posturais e comer) no in?cio do estudo. Foi considerada a presen?a de decl?nio funcional quando houve redu??o na pontua??o total das ABVD, as quais foram avaliadas mediante uma escala tipo Likert de 5 pontos. Foram analisadas todas as vari?veis independentes do Estudo 1, mais o estado de mobilidade, cognitivo (teste de Pfeiffer), h?bitos t?xicos e atividade f?sica, al?m de vari?veis dependentes do tempo. Para a an?lise estat?stica, foi utilizado o m?todo atuarial, o teste log-rank, a an?lise univariada de Cox e a regress?o de Cox. A coorte esteve composta por 280 idosos: 140, 50,0% (IC 95%: 44,2-55,8%), sofreram decl?nio funcional, 94, 33,6% (IC 95%: 28,3-39,3%) mantiveram a capacidade funcional, e 40, 14,3% (IC 95%: 10,7-18,9%), apresentaram melhora funcional em uma ou mais avalia??es. A probabilidade acumulada de manuten??o funcional foi de 44,0% (IC 95%: 37,7-50,2%) aos 24 meses. A capacidade de se alimentar foi a que apresentou maior decl?nio durante o per?odo (-0,54 pontos), seguido por deambula??o (-0,43), vestir-se (-0,35), transfer?ncias posturais (-0,31), banho (-0,29), higiene pessoal (-0,24) e ir ao banheiro (-0,22). O modelo multivariado mostrou que os fatores predictores de decl?nio funcional foram a incapacidade cognitiva grave (HR=1,98; p=0,003), decl?nio da contin?ncia (HR=1,70; p=0,013) e incid?ncia de hospitaliza??es (HR=1,65; p=0,023). / The main objectives of this work were: to verify the prevalence of functionaldisability (FD) inthe basic activities of daily living (BADL) and its associated factors (Study 1) and verify the incidence of functional decline and predictor factors of functional decline (Study 2) in institutionalized older people. The sample of the study was formed by individuals aged 60 years and over belonging to 10 nursing homes (NH) in Natal/RN, being excluded hospitalized or palliative care residents. The Study 1 is a cross-sectional study (October-December 2013) and FD was evaluated by Katz scale and characterized when there was limitation in one or more BADL (eating, sphincter control, transferring, personal hygiene, dressing and bathing). As independent variables sociodemographic, instituition-related health-related variables were considered. The Chi-square test, Fisher's exact test or the linear Chi-square test for the bivariate analysis and logistic regression for multivariate analysis were applied. The sample consisted of 321 individuals and the prevalence of FD was 72.9% (95% CI: 67.8-77.5%). The most affected task was 'bathing', followed by 'dressing' and 'toileting.' The final model found association with private NH (PR=1.33, p<0.001), age 83 and over (RP=1.26, p=0.003), reason for institutionalization ?lack of caregiver? (RP=1.17, p=0.033) and osteoporosis (RP=1.23, p=0.045), adjusted by sex. The Study 2 is a 24-months longitudinal study with follow-up every 6 months (5 waves). Apart from the criteria considered in the Study 1, residents with FD for all BADL (bathing, personal hygiene, dressing, toileting, walking, transferring and eating) at baseline were excluded. The presence of functional decline was defined when there was a reduction the total score of BADL, which were assessed by a 5-point Likert scale. All independent variables of the Study 1 were considered, as well asthe mobility status, cognitive status (Pfeiffer test), toxic habits, physical activity and time-dependent variables. Statistical analysis was performed using the actuarial method, log-rank test, Cox univariate analysis and Cox regression. The cohort was composed of 280 individuals: 140, 50.0% (95% CI: 44.2-55.8%) experienced functional decline; 94, 33.6% (95% CI: 28.3-39.3%), maintained their functional capacity, and; 40, 14.3% (95% CI: 10.7-18.9%), showed functional improvement at one or more waves. The cumulative probability of functional maintenance was 44.0% (95% CI: 37.7-50.2%) at 24 months. The ability to eat showed the largest decline during the period (-0.54 points), followed by walking (-0.43), dressing (-0.35), transferring (-0.31), bathing (-0.29), personal hygiene (-0.24) and toileting (-0.22). The final model showed that the predictors factors of functional decline were severe cognitive impairment (HR=1.96, p=0.001), continence decline (HR=1.85, p=0.002) and incidence of hospitalizations (HR=1.62, p=0.020).

In this context it is important to conduct research to determine prognosis of different types of prosthetic rehabilitation and determination of the main problems affecting this type of treatment. Thus, the objective of this study was to assess the prosthetic conditions of individuals rehabilitated with implant-supported prosthesis. In this cross-sectional study 153 patients were treated, accounting for a sample of 509 implants. The failures were observed by clinical and radiographic examination. The results showed that the fracture (0.2%) loss (0.4%) and loosening of the screws (3.3%) were failures are less frequent. The fracture structures as the resin (12.4%), porcelain (5.5%) and metallic (1.5%), loss of resin that covers the screw (23.8%) and loss of retention overdentures on implants (18.6%) had a higher occurrence. The failure of adaptation between the abutment and the implant (6.9%) and especially between the prosthesis and the abutment (25.4%) had a high prevalence and, when related to other parameters showed a significant association, particularly with the cemented prosthesis (OR = 6.79). It can be concluded that to minimize the appearance of failures, protocols must be observed from diagnosis to the settlement and control of prostheses on implants, particularly with respect to technical steps of the making of the prosthesis and care in radiographic evaluating the fit between their components / Os crit?rios de avalia??o dos casos tratados com implantes osseointegrados s?o baseados em testes cl?nicos e exames radiogr?ficos.

Neste estudo transversal foram atendidos 153 pacientes, contabilizando uma amostra de 509 implantes. As falhas foram observadas atrav?s do exame cl?nico e radiogr?fico. Os resultados demonstraram que a fratura (0,2%), a perda (0,4%) e o afrouxamento dos parafusos (3,3%) foram as falhas menos frequentes. A fratura das estruturas como a resina (12,4%), porcelana (5,5%) e met?lica (1,5%), a perda da resina que recobre o parafuso de fixa??o (23,8%) e a perda de reten??o nas pr?teses overdentures (18,6%), tiveram uma ocorr?ncia maior. A falha de adapta??o, entre o pilar e o implante (6,9%) e principalmente entre a pr?tese e o pilar (25,4%) teve uma alta preval?ncia e, quando relacionada com outros par?metros, demonstrou uma associa??o significativa, principalmente com a fixa??o do tipo cimentada (OR= 5,39). Pode-se concluir que para minimizar o aparecimento de falhas, protocolos devem ser observados desde o diagn?stico at? o assentamento e controle das pr?teses sobre implantes, principalmente com rela??o aos passos t?cnicos da confec??o da pr?tese e com o cuidado em avaliar radiograficamente a adapta??o entre seus componentes
