Resumen: En | Texto: En | PDF: En

Abstract The genetic basis of oral epithelial (OED) is unknown, and there is no reliable method for evaluating the risk of malignant transformation. Somatic mutations are responsible for the transformation of dysplastic mucosa to invasive cancer. In addition, these genomic variations could represent objective markers of the potential for malignant transformation. We performed whole-exome sequencing of 10 OED samples from Brazilian and Chilean patients. Using public genetic repositories, we identified 41 deleterious variants that could produce high-impact changes in the amino acid structures of 38 genes. In addition, the variants were filtered according to normal skin and Native American genome profiles. Finally, 13 genes harboring 15 variants were found to be exclusively related to OED. High-grade epithelial dysplasia samples showed a tendency to accumulate highly deleterious variants. We observed that 62% of 13 OED genes identified in our study were also found in head and neck squamous cell carcinoma. Among the shared genes, eight were not identified in oral squamous cell carcinoma. To our knowledge, we have described for the first time 13 genes that are found in OED in a Latin American population, of which five genes have already been observed in oral squamous cell carcinoma. Through this study, we identified genes that may be related to basal biological functions in OED.

Resumen: En | Texto: En | PDF: En

Abstract The aim of this study was to describe the prevalence, clinicopathological, and prognostic features of acinic cell carcinoma (AciCC) of the oral and maxillofacial region. AciCC cases were retrospectively retrieved from 11 pathology centers of three different countries. Medical records were examined to extract demographic, clinical, pathologic, and follow-up information. A total of 75 cases were included. Females (65.33%) with a mean age of 45.51 years were mostly affected. The lesions usually presented as an asymptomatic (64.28%) nodule (95.66%) in the parotid gland (70.68%). The association of two histopathological patterns was the most common finding (48.93%) and the tumors presented mainly conventional histopathological grades (86.11%). Surgical treatment was performed in the majority of the cases (59.19%). Local recurrence was observed in 20% of the informed cases, regional metastasis in 30.43%, and distant metastasis in 12.50%. The statistical analysis showed that the cases with a solid histopathological pattern (p=0.01), high-grade transformation (p=0.008), recurrence (p=0.007), and regional metastasis (p=0.03) were associated with poor survival. In conclusion, high histopathological transformation, presence of nodal metastasis, and recurrence were prognostic factors for AciCC of the oral and maxillofacial region.

Resumen: En | Texto: En | PDF: En

Abstract This study aimed to evaluate the contribution of oral and maxillofacial pathology laboratories (OMPLs) in Brazilian public universities to the diagnosis of lip, oral cavity, and oropharyngeal squamous cell carcinoma (SCC). A cross-sectional study was performed using biopsy records from a consortium of sixteen public OMPLs from all regions of Brazil (North, Northeast, Central-West, Southeast, and South). Clinical and demographic data of patients diagnosed with lip, oral cavity, and oropharyngeal SCC between 2010 and 2019 were collected from the patients’ histopathological records. Of the 120,010 oral and maxillofacial biopsies (2010-2019), 6.9% (8,321 cases) were diagnosed as lip (0.8%, 951 cases), oral cavity (4.9%, 5,971 cases), and oropharyngeal (1.2%, 1,399 cases) SCCs. Most cases were from Brazil’s Southeast (64.5%), where six of the OMPLs analyzed are located. The predominant profile of patients with lip and oral cavity SCC was Caucasian men, with a mean age over 60 years, low schooling level, and a previous history of heavy tobacco consumption. In the oropharyngeal group, the majority were non-Caucasian men, with a mean age under 60 years, had a low education level, and were former/current tobacco and alcohol users. According to data from the Brazilian National Cancer Institute, approximately 9.9% of the total lip, oral cavity, and oropharyngeal SCCs reported over the last decade in Brazil may have been diagnosed at the OMPLs included in the current study. Therefore, this data confirms the contribution of public OMPLs with respect to the important diagnostic support they provide to the oral healthcare services extended by the Brazilian Public Health System.

Aim To compare the profile and overall survival of young adults and elderly people diagnosed with SCC. Methods A retrospective study was carried out at a High Complexity Oncology Unit, between 2010 and 2016. A descriptive analysis, a bivariate analysis using the chi-square and Fisher’s exact test and the Kaplan-Meier estimator were performed. The predictor variables were tested using the log-rank test and those with statistical significance and the literature were maintained for the Cox regression model. Results 282 cases of SCC were recorded, with only 12.4% diagnosed in young adults. The profile was similar between groups, with the majority of cases of the disease occurring in males, smokers and alcohol consumers. The lesions predominantly located on the tongue and were diagnosed in an advanced stage of the disease, resulting in 35.7% of deaths. The median survival time was 30 months in the elderly and 31 months in young people. In the multivariate analysis, age was not statistically significant, only staging and treatment were predictors of reduced overall survival. Conclusion Tumor staging, and treatment were prognostic factors for the disease.

Resumen: En | Texto: En | PDF: En

Abstract The aim of this systematic review was to evaluate published papers regarding the micronucleus assay in oral mucosal cells of patients undergoing orthodontic therapy (OT). A search of the scientific literature was made in the PubMed, Scopus, and Web of Science databases for all data published until November, 2021 using the combination of the following keywords: “fixed orthodontic therapy,” “genetic damage”, “DNA damage,” “genotoxicity”, “mutagenicity”, “buccal cells”, “oral mucosa cells,” and “micronucleus assay”. The systematic review was designed according to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. Nine studies were retrieved. Some authors demonstrated that OT induces cytogenetic damage in oral mucosal cells. Out of the nine studies included, two were classified as strong, five as moderate, and two as weak, according to the quality assessment components of the Effective Public Health Practice Project (EPHPP). Meta-analysis data revealed no relationship between mutagenicity in oral cells and OT in different months of treatment. At one month, the SMD = 0.65 and p = 0.08; after three months of OT, the SMD = 1.21 and p = 0.07; and after six months of OT, the SMD = 0.56 and p = 0.11. In the analyzed months of OT, I2 values were >75%, indicating high heterogeneity. In summary, this review was not able to demonstrate that OT induces genetic damage in oral cells. The study is important for the protection of patients undergoing fixed OT, given that mutagenesis participates in the multi-step process of carcinogenesis.

Abstract: The osteolytic activity of odontogenic cysts and tumors is directly associated with their growth and aggressiveness. The influence of proteins expressed by epithelial and mesenchymal cells on this biological event differs between indolent cystic lesions, aggressive cystic lesions, and odontogenic tumors. The objective of this study was to compare the immunohistochemical expression of factors that stimulate (receptor activator of nuclear factor kappa-Β ligand – RANKL, cathepsin K – CatK and matrix metallopeptidase 8 – MMP-8) and inhibit (osteoprotegerin – OPG) osteoclastogenesis between dentigerous cyst (DC), glandular odontogenic cyst (GOC), odontogenic keratocyst (OKC), and ameloblastoma (AB). Paraffin-embedded sections of nine DCs, nine GOCs, 20 OKCs, 21 ABs, and four dental follicles (DFs) were subjected to immunohistochemistry. Immunoreactivity was analyzed semiquantitatively and quantitatively in epithelium and connective tissue, respectively. The proteins were immunoexpressed in epithelial and mesenchymal cells of all lesions studied. The expression of RANKL and CatK was higher in OKC, AB, and GOC (p<0.005). Higher expression of OPG was found in DF and DC compared to the other markers (p<0.005). MMP-8 expression was high in GOC and OKC. This study demonstrated the differential expression of factors that inhibit and stimulate bone resorption during the development of DC, GOC, OKC, and AB. Higher expression of RANKL and CatK was observed in more aggressive lesions. OPG appears to be one of the molecules responsible for the slower growth of DC.

RESUMO Introdução: Em várias condições, a estabilidade dos resultados é um grande desafio para a Ortodontia. Estudos prévios relataram que a recidiva ocorre, comumente, ao longo dos anos, após o término do tratamento ortodôntico. Objetivo: O objetivo da presente pesquisa foi avaliar as alterações transversais da arcada dentária em longo prazo de pacientes Classe II, divisão 1, tratados com aparelho extrabucal cervical e aparelho fixo. Métodos: Modelos de gesso de 20 pacientes tratados com AEB cervical, sem extrações dentárias, foram escaneados e avaliados em três momentos distintos: inicial (T1), pós-tratamento imediato (T2) e acompanhamento de longo prazo (T3, mínimo de 20 anos). A distância transversal entre os caninos superiores e inferiores, pré-molares e primeiros molares foi medida. Resultados: Foi observado aumento estatisticamente significativo durante o tratamento para todas as distâncias transversais dos dentes superiores (p < 0,05). Por sua vez, foi observada redução significativa em longo prazo (p < 0,05). Para os dentes inferiores, a distância transversal intercaninos apresentou constrição estatisticamente significativa no período de contenção (p < 0,05). A distância dos primeiros molares inferiores aumentou significativamente com o tratamento (p < 0,05) e permaneceu estável em longo prazo. As alterações observadas para os outros dentes ou outros tempos foram consideradas sem significância estatística. Conclusões: Para a amostra estudada, as alterações transversais ocorreram durante as fases de tratamento e contenção em pacientes Classe II, divisão 1, tratados com aparelho extrabucal de tração cervical e aparelho fixo. A recidiva foi considerada estatisticamente significativa, mesmo com a instituição de um protocolo de contenção.

ABSTRACT Introduction: In several conditions, outcome stability is a great challenge for Orthodontics. Previous studies have reported that relapse commonly occurs along the years after orthodontic treatment finishing. Objective: The aim of the present study was to evaluate in the long-term transversal dental arch changes of Class II division 1 patients treated with cervical headgear and fixed appliance. Methods: Plaster study casts of 20 patients treated with cervical headgear without dental extractions were 3D-scanned and evaluated in three distinct times: initial (T1), immediate post-treatment (T2) and long-term retention (T3 - minimum 20 years). Transversal teeth distance of maxillary and mandibular canines, premolars and first molars were measured. Results: A statistically significant increase during treatment was observed for all maxillary teeth transversal distances (p< 0.05). In turn, a significant reduction was observed in the long term (p<0.05). For the mandibular teeth, canine transversal distance presented statistically significant constriction in the retention period (p<0.05). Mandibular first molars distance was significantly expanded by treatment (p<0.05) and remained stable in the long term. The changes observed for the other teeth or other times were considered not statistically relevant. Conclusions: For the accessed sample, transversal changes occurred during treatment and retention phases in Class II division 1 patients treated with cervical headgear and fixed appliance. Relapse was considered statistically relevant, even with the institution of a retention protocol.

RESUMO Objetivo: O presente estudo teve como objetivo investigar a relação entre a inclinação dentária e as dimensões ósseas e gengivais em dentes anteriores superiores. Métodos: Esse estudo transversal incluiu imagens de tomografia computadorizada de feixe cônico (TCFC) de 160 dentes anteriores superiores divididos em três grupos (incisivo central, incisivo lateral e canino). Todos os pacientes tinham 18 anos ou mais, não tinham tratamento ortodôntico prévio nem história clínica que pudesse afetar as dimensões ósseas ou gengivais. A inclinação dentária, a espessura do osso e da gengiva e as distâncias da junção cemento-esmalte à crista óssea alveolar e à margem gengival foram medidas na face vestibular. As correlações foram analisadas por meio dos testes de Pearson e de correlação parcial (p≤0,05). Resultados: Nos incisivos centrais, a inclinação dentária foi positiva e significativamente relacionada à espessura do osso apical (R = 0,34, p= 0,001). Nos caninos, a inclinação dentária foi negativa e significativamente relacionada à espessura do osso cervical (R = - 0,34, p= 0,01) e positivamente associada à espessura do osso apical (R = 0,36, p= 0,01) e à distância entre a margem gengival e a junção cemento-esmalte (R = 0,31, p= 0,03). Nos incisivos laterais, a inclinação do dente não foi associada às dimensões do osso ou da gengiva. Conclusões: Nos incisivos centrais, quanto maior a inclinação vestibular do dente, maior a espessura do osso apical. Nos caninos, quanto maior a inclinação vestibular do dente, menor a espessura do osso cervical, maior a espessura do osso apical e maior a margem gengival. As dimensões ósseas e gengivais devem ser avaliadas ao se planejar o tratamento ortodôntico envolvendo a movimentação vestibular dos incisivos centrais e caninos.

ABSTRACT Objective: The present study aimed to investigate the relationship between tooth inclination and gingival and bone dimensions in maxillary anterior teeth. Methods: This cross-sectional study included cone-beam computed tomography (CBCT) images of 160 maxillary anterior teeth (30 individuals). Tooth inclination, gingival and bone thickness, and distances from cementoenamel junction to alveolar bone crest and gingival margin were measured in the labial surface. The correlations were analyzed using Pearson and partial correlation tests (p≤0.05). Results: In the central incisors, tooth inclination was positively and significantly related to apical bone thickness (R = 0.34, p= 0.001). In the canines, tooth inclination was negatively and significantly related to cervical bone thickness (R = - 0.34, p= 0.01) and positively associated to apical bone thickness (R = 0.36, p= 0.01) and to gingival margin-cementoenamel junction distance (R = 0.31, p= 0.03). In the lateral incisors, tooth inclination was not associated with gingival or bone dimensions. Conclusions: In the central incisors, the greater the labial tooth inclination, the greater is the apical bone thickness. In the canines, the greater the labial tooth inclination, the smallest is the cervical bone thickness, the greater is the apical bone thickness, and the greater is the gingival margin. Gingival and bone dimensions should be assessed when planning orthodontic treatment involving buccal movement of central incisors and canines.

Resumo A displasia cementária periapical é um distúrbio de formação e remodelação do tecido ósseo que durante o seu desenvolvimento sofreu alteração na diferenciação celular, resultando num tecido malformado. Apresenta-se predominantemente em pessoas do gênero feminino, etnia negra e na faixa etária dos 40 anos. Pode ser confundida com as lesões periapicais inflamatórias de origem endodôntica devido à semelhança de suas características radiográficas. A displasia cementária periapical geralmente é identificada por meio de exames radiográficos de rotina, pois tende a não apresentar sinais e sintomas clínicos. O diagnóstico precoce torna-se relevante para o planeamento terapêutico dessa patologia, que na maioria dos casos é conservador e se traduz no acompanhamento clínico e radiográfico. O objetivo deste estudo foi apresentar um caso de displasia cementária periapical, diagnosticado precocemente na fase inicial, com acompanhamento de sete anos, com foco nos métodos diagnósticos e tratamento disponíveis.

Abstract Periapical cemental dysplasia is a disorder of bone tissue formation and remodeling where, during its development, bone tissue suffers a change in cell differentiation, resulting in malformed tissue. It presents predominantly in the female sex, black ethnicity, and the age group of 40 years. It can be confused with inflammatory periapical lesions of endodontic origin due to its similar radiographic characteristics. Periapical cemental dysplasia is usually identified through routine radiographic examinations, as it tends to show no clinical signs and symptoms. Early diagnosis is important for the treatment plan of this pathology, which, in most cases, is conservative and translates into clinical and radiographic monitoring. The aim of this study was to present a case of periapical cemental dysplasia with early diagnosis in the first stage and a seven-year follow-up, focusing on the diagnostic and treatment methods available.

Resumo: O objetivo deste trabalho foi identificar a temperatura base mínima (Tb) e a temperatura base máxima (TB), para predizer o requerimento térmico de seis estágios fenológicos de acessos de feijoa (Acca sellowiana). Durante dez safras não sequenciais (2004 a 2017), 247 acessos, mantidos no Banco Ativo de Germoplasma, em São Joaquim, no estado de Santa Catarina, Brasil, tiveram seus dados registrados quanto a: início de brotação (IB), início de floração (IF), fim de floração (FF), início de colheita (IC) e fim de colheita (FC). A Tb e a TB foram estimadas pelo método de mínima variabilidade de Arnold, e os requerimentos térmicos foram obtidos pelo método de Ometto. Os valores de Tb a 7,76°C e TB a 17,0°C foram necessários quando as plantas de feijoa começaram a crescer (estágio IB), logo após o inverno; e Tb a 10,6°C e TB a 19,5°C foram os valores calculados de IB até IC. A brotação dos acessos iniciou-se em meados de setembro (50,6%); a floração ocorreu predominantemente em novembro (90%); e a colheita iniciou-se em março, tendo-se estendido até maio. São necessários cerca de 176 dias, com 1.014,4 graus-dia, para completar o ciclo produtivo desde IB até IC. Os acessos de feijoa de maturação precoce, intermediária e tardia apresentam diferentes exigências de requerimento térmico.

Abstract: The objective of this work was to identify the minimum base temperature (Tb) and the maximum base temperature (TB) to predict the thermal time for six phenological stages of feijoa (Acca sellowiana) accessions. During ten noncontinuous harvests (2004 to 2017), 247 feijoa accessions, maintained in the Feijoa Active Germplasm Bank, in São Joaquim, in the state of Santa Catarina, Brazil, had their data recorded for: initial sprouting (IS), initial flowering (IF), end of flowering (EF), beginning of harvest (BH), and end of harvest (EH). Tb and TB were estimated by the Arnold’s method of least variability, and the TT requirements were obtained by Ometto’s method. Tb at 7.76°C and TB at 17.0°C were necessary when feijoa plants started growing (IS stage) just after winter; and Tb at 10.6°C and TB at 19.5°C were the calculated values from IS until BH. The budding stage of the accessions began in the mid-September (50.6%); flowering occurred predominantly in November (90%); and harvest began in March and lasted until May. About 176 days, with 1,014.4 growing degree-days, are necessary to complete the productive cycle from IS until BH. The early, intermediary, and late fruit-ripening accessions show different thermal time requirements.

RESUMO Objetivo Analisar o perfil e a sobrevida de adultos jovens com carcinoma de células escamosas oral, atendidos entre 2010 a 2016 na Unidade de Alta Complexidade em Oncologia de Feira de Santana, Brasil. Métodos Coorte retrospectiva, realizada através das informações dos prontuários de todos os pacientes jovens atendidos no referido centro. Foi realizada análise descritiva das variáveis, teste exato de Fisher, curva de Kaplan-Meier e teste log rank. Resultados Um total de 35 pacientes foram registrados. A maioria era do sexo masculino, fumantes e etilistas. Os tumores estavam localizados predominantemente em língua, diagnosticados tardiamente e classificados como bem diferenciado, tendo como tratamento de escolha cirurgia associada a radioterapia e quimioterapia. O tempo mediano de sobrevida foi de 31 meses e 22,8% dos pacientes foram a óbito. As variáveis que apresentaram significância estatística em relação ao tempo de sobrevida foram a localização do tumor e o tipo de tratamento. Conclusão O perfil e o baixo tempo de sobrevida refletem a necessidade de uma maior atenção à doença nesta população.

RESUMEN Objetivo Analizar el perfil y la supervivencia de adultos jóvenes con carcinoma de células escamosas atendidos en el Centro de Alta Complejidad en Oncología de Feira de Santana (Brasil), durante el periodo 2010-2016. Métodos cohorte retrospectivo realizado mediante la información de registros médicos de todos los pacientes jóvenes atendidos en el centro médico mencionado. Asimismo, se hizo un análisis descriptivo de las variables, test exacto de Fisher, curva de Kaplan-Meier y una prueba de rango logarítmico.

ABSTRACT Objective To analyze the profile and survival in young adults with oral squamous cell carcinoma, attended at the High Complexity in Oncology of Feira de Santana, Brazil, between 2010 and 2016. Methods Retrospective cohort, performed through the information of the medical records of all young patients attended in the referred center. Descriptive analysis of the variables, Fisher's exact test, Kaplan-Meier curve and log-rank test were performed. Results A total of 35 patients were registered. The majority were male, smokers and former alcoholics. Tumors were predominantly localized in the tongue, diagnosed at late stages, classified as well differentiated and treated mainly with surgery associated to radiotherapy and chemotherapy. The median survival time was 31 months and 22.8% of the patients died. The variables that presented statistical significance in relation to the survival time were the tumor site and the type of treatment. Conclusion The profile and low survival time reflect the need for greater attention to the disease in this population.

Resumen: En | Texto: En | PDF: En

Polymers such as the biocompatible polyhydroxybutyrate (PHB) and the polysaccharide chitosan (Chi), a pH-sensitive polymer, have been studied for drug delivery applications and scaffolds production. In this work, matrices of PHB and Chi were produced by compression molding (SPHB-Chi) and loaded with a broad-spectrum biocide chlorhexidine (CHX) (SPHB-Chi-CHX). The matrices were analyzed by scanning electron microscope (SEM). The SPHB-Chi capacity to absorb and deliver CHX was evaluated by UV-Vis. The antibacterial activity of the samples against S. aureus, P. aeruginosa and E. coli (most common pathogens that cause infection in several body sites) was evaluated using the disk-agar diffusion method. The CHX release results were fitted by the Power Law model. The results suggested that the morphology and the CHX delivery profile were directly related to the Chi amount in the samples and also showed that the SPHB-Chi-CHX is able to inhibit the microorganism proliferation, constituting it as a potential candidate for oral applications.

RESUMO Introdução: Modelos de cuidado contínuo baseiam recentes estratégias em HIV, infecções sexualmente transmissíveis e hepatite C (HCV). Métodos: Desenvolveram-se modelos de contínuo do cuidado em HIV, HCV e sífilis congênita incluindo todas as etapas da atenção, desde a promoção e a prevenção até o controle clínico/cura. O modelo baseou a intervenção QualiRede, desenvolvida em parceria entre universidade e Sistema Único de Saúde (SUS), direcionada a gestores e demais profissionais de 6 regiões de saúde prioritárias em São Paulo e Santa Catarina. Selecionaram-se indicadores para cada etapa do contínuo do cuidado, provenientes dos sistemas de informação do SUS e dos questionários de avaliação de processo Qualiaids e QualiAB. Os indicadores formaram a base técnica de duas oficinas com profissionais e gestores de cada região: a primeira para identificar problemas e formar um Grupo Técnico Regional; e a segunda para construir planos de ação e metas a fim de melhorar o desempenho regional. Resultados: Os indicadores estão disponíveis no website www.qualirede.org. As oficinas ocorreram em quatro regiões de São Paulo (Alto Tietê, Baixada Santista, Grande ABC e Registro) e uma região de Santa Catarina (Foz do Rio Itajaí), resultando em planos regionais em São Paulo, mas não em Santa Catarina. Observou-se domínio limitado dos novos protocolos para HIV e HCV e uso incipiente de indicadores na rotina dos serviços. Conclusão: Melhorar o desempenho do contínuo do cuidado exige apropriação dos indicadores de desempenho e coordenação integrada dos fluxos de atenção em todos os níveis de gestão.

ABSTRACT Introduction: Care continuum models have supported recent strategies against sexually transmitted diseases, such as HIV and Hepatitis C (HCV). Methods: HIV, HCV, and congenital syphilis care continuum models were developed, including all stages of care, from promotion/prevention to clinical control/cure. The models supported the intervention QualiRede, developed by a University-Brazilian National Health System (SUS) partnership focused on managers and other professionals from six priority health regions in São Paulo and Santa Catarina. Indicators were selected for each stage of the care continuum from the SUS information systems and from the Qualiaids and QualiAB facility’s process evaluation questionnaires. The indicators acted as the technical basis of two workshops with professionals and managers in each region: the first one to identify problems and to create a Regional Technical Group; and the second one to design action plans for improving regional performance. Results: The indicators are available at www.qualirede.org. The workshops took place in the regions of Alto Tietê, Baixada Santista, Grande ABC, and Registro (São Paulo) and of Foz do Rio Itajaí (Santa Catarina), which resulted in regional action plans in São Paulo, but not in Santa Catarina. A lack of awareness was observed regarding the new HIV and HCV protocols, as well as an incipient use of indicators in routine practices. Conclusion: Improving the performance of the care continuum requires appropriation of performance indicators and coordination of care flows at local, regional, and state levels of management.
