ABSTRACT

Abstract New methods of early detection and risk assessment have been studied aiming to predict the prognosis of patients and directing a specialized treatment of the oral tongue squamous cell carcinoma (OTSCC). In this context, several molecular biomarkers have been investigated for this purpose, and, among them, the heat shock protein 27 (HSP27) can be named. The study aimed to analyze whether heat shock protein 27 (HSP27) exerts any influence on OTSCC, correlating its immunoexpression with clinicopathological parameters, and patient survival. The sample comprised 55 OTSCC cases and 20 normal oral mucosa specimens. The malignancy grading systems proposed by the WHO in 2005, Brandwein-Gensler et al., and Almangush et al. were applied in a histomorphological study. HSP27 expressions were evaluated through the Immunoreactivity Score System (IRS). Significant values were considered at p <0.05 for all statistical tests. Higher IRS results were observed for normal oral mucosa specimens when compared to OTSCC cases (p <0.001). No significant associations between HSP27 immunostaining, the analyzed clinicopathological parameters and patient survival were observed. The results of the present study indicate lower HSP27 expression in OTSCC cases compared to normal oral mucosa specimens. Thus, HSP27 expression does not seem to influence patient prognosis.


Resumo Novos métodos de detecção precoce e avaliação de risco estão sendo estudados com o intuito de predizer o prognóstico dos pacientes e direcionar um tratamento diferenciado. Neste contexto, vários biomarcadores moleculares têm sido investigados com esta finalidade, dentre eles a heat shock protein 27 (HSP27). Esta pesquisa objetivou analisar se a HSP27 exerce alguma influência nos carcinomas de células escamosas de língua oral (CCELO), correlacionando a sua imunoexpressão com parâmetros clinicopatológicos e com a sobrevida dos pacientes. A amostra foi constituída por 55 casos de CCELO e 20 espécimes de mucosa oral normal. Os sistemas de gradação de malignidade propostos pela OMS em 2005, Brandwein-Gensler et al. e Almangush et al. foram aplicados em um estudo histomorfológico. A expressão da HSP27 foi avaliada através do Sistema de Escore de Imunorreatividade (IRS). Para todos os testes estatísticos foram considerados valores significativos com p<0,05. Foi observado um maior IRS para a mucosa oral normal quando comparado aos casos de CCELO (p<0,001). Não foram encontradas associações significativas entre a imunomarcação da HSP27 com os parâmetros clinicopatológicos analisados e com a sobrevida dos pacientes. Os resultados do presente estudo indicam uma menor expressão da HSP27 nos casos de CCELO quando comparados aos espécimes de mucosa oral normal. Assim, a expressão da HSP27 parece não influenciar o prognóstico dos pacientes.

ABSTRACT

Solitary fibrous tumor (SFT) is a neoplasm of fibroblastic/myofibroblastic origin with intermediate biological behavior. We report here two cases of SFT affecting an unusual anatomical site in 58-year-old and 40-year-old female patients and discuss the differential diagnosis of this lesion. In case 01, the lesion showed the clinical appearance of an asymptomatic "blister" with normal color, rubbery consistency, measuring 0.3 cm, and affected the lower lip; while in case 02, a symptomatic red nodular lesion with a soft consistency and measuring 0.5 cm affected the floor of the mouth. Excisional biopsies were performed. Microscopically, two well-delimited benign neoplasms were observed, exhibiting the proliferation of ovoid to spindle-shaped mesenchymal cells, vascular spaces with staghorn arrangement, and the absence of mitosis figures. Immunohistochemistry was performed in case 01 to assist in the diagnosis. Weak and diffuse immunostaining was observed for α-SMA and intense and diffuse immunopositivity for Bcl-2 and CD34. Based on histopathological and immunohistochemical features, a diagnosis of SFT was rendered in both cases. The low occurrence and nonspecific clinical features of oral SFT may make its clinical diagnosis difficult. Also, morphological and immunohistochemical are essential for differential diagnosis with other mesenchymal neoplasms.(AU)


O tumor fibroso solitário (TFS) é uma neoplasia de origem fibroblástica/miofibroblastica com comportamento biológico intermediário. Nesse artigo relatamos dois casos de TFS afetando sítios anatômicos incomuns em pacientes do sexo feminino de 58 anos e 40 anos e discutir os seus diagnósticos. No caso 01 clinicamente a lesão apresentou um aspecto de "bolha" assintomática, coloração normal da mucosa, consistência borrachoide medindo 0,3 cm, em região de lábio inferior, enquanto que no caso 02, como uma lesão sintomática, vermelha, nodular com consistência mole e medindo 0,5 cm afetando o assoalho bucal. As biópsias excecionais foram realizadas. Microscopicamente, observamos duas lesões neoplásicas bem delimitadas exibindo uma proliferação de células mesenquimais variando de ovoides a fusiformes, vasos sanguíneos em formato de "chifre de veado", com ausência de figuras de mitoses. No caso 01 foi realizado análise imuno-histoquímica para auxiliar no diagnóstico. Foi observado uma marcação fraca e difusa de α-SMA e uma intensa e difusa imunopositividade para o Bcl-2 e CD34.Baseado nos achados histopatológicos e imuno-histoquímicos o diagnóstico de TFS foi estabelecido em ambos os casos. A baixa ocorrência e os achados clínicos inespecíficos do TFS oral podem dificultar o diagnóstico clínico. Além disso, as análises morfológicas e imuno-histoquimicas são essenciais para realização do diagnóstico diferencial com outras neoplasias mesenquimais.(AU)_

ABSTRACT

Abstract The biological behavior of lesions is highly dependent on the imbalance between their proliferative and apoptotic capacity. This study evaluated a correlation between the proliferative and apoptotic rates of different oral vascular anomalies (VAs) by analyzing the immunoexpression of proliferation (Ki-67) and apoptosis (Bcl-2 and Bax) markers in endothelial cells of 20 cases of GLUT-1 positive infantile hemangiomas (IHs), 20 cases of pyogenic granulomas (PGs) and 20 cases of vascular malformations (VMs). Immunoexpression analysis of Ki-67, Bcl-2 and Bax revealed a lower median percentage of positive cells in VMs cases compared to IHs and PGs cases (P <0.001). The Wilcoxon signed‐rank test showed significantly higher percentages of immunostaining for Bax than for Bcl‐2 in IHs (P = 0.048). In the group of PGs, a positive correlation was observed between the immunoexpressions of Ki-67 and Bax (r = 0.476; P = 0.034). Although oral IHs, PGs and VMs present similar clinical and histopathological features, each of these lesions has its etiopathogenic particularities. The results of this study suggest that different biological behaviors of VAs may be related to differences in the proliferative and apoptotic profiles of their endothelial cells.


Resumo O comportamento biológico das lesões é altamente dependente do desequilíbrio entre sua capacidade proliferativa e apoptótica. Neste estudo, avaliou-se se existe correlação entre as taxas proliferativas e apoptóticas de diferentes anomalias vasculares orais (AVs) analisando a imunoexpressão de marcadores de proliferação (Ki-67) e apoptose (Bcl-2 e Bax) em células endoteliais de 20 casos de hemangiomas infantis GLUT-1 positivos (HIs), 20 casos de granulomas piogênicos (GPs) e 20 casos de malformações vasculares (MVs). A análise de imunoexpressão de Ki-67, Bcl-2 e Bax revelou uma porcentagem mediana menor de células positivas nos casos de MVs em comparação aos casos de HIs e GPs (P <0,001). O teste de Wilcoxon mostrou porcentagens significativamente maiores de imunocoloração para Bax do que para Bcl-2 em HIs (P = 0,048). No grupo dos GPs, foi observada correlação positiva entre as imunoexpressões de Ki-67 e Bax (r = 0,476; P = 0,034). Embora HIs, GPs e MVs orais apresentem características clínicas e histopatológicas muito semelhantes, cada uma dessas lesões tem suas particularidades etiopatogênicas. Os resultados deste estudo sugerem que diferentes comportamentos biológicos dos AVs podem estar relacionados a diferenças nos perfis proliferativo e apoptótico de suas células endoteliais.

ABSTRACT

COVID-19 was identified to be caused by a new coronavirus named as SARS-CoV-2. Since the outbreak of this disease, World Health Organization (WHO) declared a global public health emergency. SARS-CoV-2 has a high estimate rate of human-tohuman transmission mainly through inhalation/ingestion/direct mucous contact with respiratory droplets. Considering this high transmission capacity, several countries have already registered cases of infection by health professionals. Even though dentists are not directly involved in the diagnosis and therapy of COVID-19 they represent undoubtedly a risk group due to high exposure and their work environment is a contagion factor for patients and staff. In this manner, the objective of this article is to approach important aspects of COVID-19 concerning dental care and provides an overview of its challenges on dental practice. For this, we used these following keywords in our research: COVID-19; dental general practice; prevention and control; infectious disease transmission; infectious disease transmission, patient to professional. Taking into account the global concern with patient care in midst of this pandemic, we address valid concerns regarding the potential means of contamination in the dental office and highlight practices and guidelines adopted in different countries to minimize risks in dental care in this global public health crisis, thus, reinforcing the challenges of dentistry in this context, highlighting the importance of rigorous preventive measures. However, there is still a lack of standardization of dental care protocols and consequently, reduce the risk of contagion.


COVID-19 foi identificada como sendo causada por um novo coronavírus denominado SARS-CoV-2. Desde o surgimento da doença, a Organização Mundial da Saúde (OMS) declarou uma emergência global de saúde pública. O SARS-CoV-2 tem uma alta taxa estimada de transmissão de pessoa para pessoa, principalmente por inalação/ingestão/contato direto da mucosa com gotículas respiratórias. Considerando essa alta capacidade de transmissão, vários países já registraram casos de infecção por profissionais de saúde. Mesmo que os dentistas não estejam diretamente envolvidos no diagnóstico e terapia do COVID-19, eles representam, sem dúvida, um grupo de risco devido à alta exposição e seu ambiente de trabalho é um fator de contágio para pacientes e equipe. Dessa forma, o objetivo deste artigo é abordar aspectos importantes do COVID-19 no que diz respeito à assistência odontológica e apresentar um panorama de seus desafios na prática odontológica. Para isso, utilizamos as seguintes palavras-chave em nossa pesquisa: COVID-19; clínica odontológica geral; prevenção e controle; transmissão de doenças infecciosas; transmissão de doenças infecciosas do paciente para o profissional. Levando em consideração a preocupação global com o atendimento ao paciente em meio a esta pandemia, foram abordadas preocupações válidas sobre os meios potenciais de contaminação no consultório odontológico e destacadas as práticas e diretrizes adotadas em diferentes países para minimizar os riscos na assistência odontológica nesta crise global de saúde pública, reforçando assim os desafios da odontologia neste contexto, evidenciando a importância de medidas preventivas rigorosas. Porém, ainda falta padronização dos protocolos de atendimento odontológico e, consequentemente, redução do risco de contágio.

ABSTRACT

Abstract Chloride intracellular channel-4 (CLIC4) is regulated by p53 and tumor necrosis factor-α (TNF-α), it is linked to the increase of transforming growth factor-β (TGF-β), and myofibroblastic differentiation in skin carcinogenesis. This study analyzed the immunoexpression of CLIC4, p53, TGF-β, TNF-α, and α-SMA in 50 actinic cheilitis (AC) and 50 lower lip squamous cell carcinoma (LLSCC). AC and LLSCC immunoexpression were categorized as score 1 (<5% positive cells), 2 (5-50%) or 3 (>50%). For CLIC4, nuclear and cytoplasmic immunostaining of epithelial cells was considered individually. For morphologic analysis, the World Health Organization criteria were used to epithelial dysplasia grade of ACs, and Bryne grading of malignancy system was applied for LLSCC. Higher nuclear CLIC4 (CLIC4n) and TGF-β were observed in ACs with low-risk of transformation, while cytoplasmic CLIC4 (CLIC4c), p53 and TNF-α were higher in the high-risk cases (p<0.05). In LLSCCs, CLIC4c was higher in cases with lymph node metastasis, advanced clinical stages, and histological high-grade malignancy. p53 expression was higher in high-grade LLSCCs, whereas TGF-β decreased as the clinical stage and morphological grade progressed (p<0.05). ACs showed an increased expression of CLIC4n and TGF-β, while CLIC4c and α-SMA were higher in LLSCCs (p<0.0001). Both lesions showed negative correlation between CLIC4n and CLIC4c, while in LLSCCs, negative correlation was also verified between CLIC4c and p53, as well as CLIC4c and TGF-β (p<0.05). Change of CLIC4 from the nucleus to cytoplasm and alterations in p53, TGF-β, TNF-α, and α-SMA expression are involved in lip carcinogenesis.


Resumo O canal intracelular de cloreto 4 (CLIC4) é regulado pela p53 e fator de necrose tumoral α (TNF-α) e está relacionado ao aumento do fator de crescimento transformador β (TGF-β) e na diferenciação miofibroblástica na carcinogênese cutânea. Este estudo analisou a imunoexpressão de CLIC4, p53, TGF-β, TNF-α e α-SMA em 50 queilites actínicas (QA) e 50 carcinomas de células escamosas de lábio inferior (CCELI). A imunoexpressão da QA e CCELI foram categorizadas em escore 1 (<5% de células positivas), 2 (5-50%) ou 3 (>50%). Para CLIC4, a imunomarcação nuclear e citoplasmática das células epiteliais foi considerada separadamente. Para análise morfológica, foram utilizados os critérios da Organização Mundial da Saúde para a gradação das displasias epiteliais nas QAs, e o sistema de gradação de malignidade de Bryne foi utilizado para os casos de CCELIs. Alta imunoexpressão de CLIC4 nuclear (CLIC4n) e TGF-β foi observada em QA de baixo risco de transformação, enquanto CLIC4 citoplasmática (CLIC4c), p53 e TNF-α foram elevadas nos casos de alto risco (p<0.05). No CCELI, a imunoexpressão de CLIC4c foi maior em caos com metástase linfonodal, estágio clínico avançado e alto grau histológico de malignidade. A expressão de p53 foi elevada em CCELI de alto grau, enquanto o TGF-β diminuiu à medida que o estádio clínico e o grau morfológico progrediram (p<0.05). QAs exibiram uma elevada expressão de CLIC4n e TGF-β, enquanto o CLIC4c e α-SMA foram elevados em CCELIs (p<0.0001). Ambas as lesões mostraram correlação negativa entre CLIC4n e CLIC4c, enquanto nos CCELIs, também se verificou correlação negativa entre CLIC4c e p53, assim como entre CLIC4c e TGF-β (p<0.05). Alteração do CLIC4 do núcleo para o citoplasma e alterações na expressão de p53, TGF-β, TNF-α, e α-SMA estão envolvidas na carcinogênese labial.

ABSTRACT

Objetivos: Analisar parâmetros sialométricos (fluxo salivar, pH e capacidade tampão) e presença de alterações orais em portadores de IRC em hemodiálise. Metodologia:A pesquisa caracteriza-se por ser estudo transversal e observacional, constituída por dados clínicos e demográficos de pacientes portadores de IRC (n=50), comparados com pacientes sistemicamente saudáveis (n=20). Utilizou-se o teste qui-quadrado e exato de Fisher para verificar a associação entre as variáveis categóricas. O Mann-Whitney foi aplicado para se obter a comparação das variáveis quantitativas entre os grupos analisados. Para todos os testes, o nível de significância adotado foi 95%. Resultados:No grupo de pacientes portadores de IRC,a maioria dos pacientes (56%) apresentou halitose, grande parte (69,5%) tinha cálculo dentário visível e 26%, alguma lesão em mucosa oral. Foi constatado CPO-D médio de 13,9. Foi encontrada uma diferença estatisticamente significativa entre os valores de fluxo salivar (p=0,001) e do pH (p=0,037) com o grupo controle, mas não houve diferença significativa nos valores da capacidade tampão da saliva, nem desses valores com a idade, o sexo, o tempo de hemodiálise, a quantidade de líquido ingerido diariamente, medicamentos em uso ou comorbidades. Conclusão:A saúde bucal dos pacientes com IRC foi considerada precária, o que pode comprometer a realização do transplante. Assim, salienta-se a importância da inserção do cirurgião dentista na equipe de assistência ao paciente com IRC. (AU)


Objective: To characterize the oral health of Chronic kidney disease (CKD) patients by evaluating salivary flow, pH and salivary buffering capacity, oral lesions, gingival bleeding, calculus and index of decayed, missing and filled teeth. Methodology: The present cross sectional, observational, analytical study, was composed of the clinical and demographic data of patients with CKD (n = 50) and compared with those systemically healthy patients (n = 20). The chi-square and Fisher's exact test were used for association between categorical variables. The Mann-Whitney test was applied to compare the quantitative variables between the groups. Level of significance of 5% was used for all the tests. Results:In the group of patients with CKD, 56% presented halitosis, 69.5% had visible dental calculus and 26% had some kinf of lesion in the oral mucosa. There was a statistically significant difference between salivary flow and pH in the group with CKD and the control group, but there was not significant difference in buffering capacity. Conclusion: The participant's oral health was considered precarious, which must be minimized, because those patients are potential transplant candidates. Therefore, it is important to point out the significance of a dentist in the assistance team of patients with CKD. (AU)

ABSTRACT

Abstract: BACKGROUND: Recurrent aphthous ulcerations are common benign ulcerated lesions on the mouth, whose etiology is poorly understood, with controversial treatment and difficult to control in clinical practice. OBJECTIVE: To evaluate the cases of recurrent aphthous ulcerations with a focus on treatment, diagnosis and etiology. METHODS: This is a retrospective study of the cases of the Oral Diagnosis service of the Rio Grande do Norte Federal University in Natal/RN. Data such as sex, age, race, location, smoking habits, types of treatment, relapsing episodes, laboratory test results and clinical characteristics were collected. The associations between the variables were analyzed using the Pearson Chi-square test (p <0.05). RESULTS: A total of 4895 patients were seen in the service over a period of 11 years. Of these, 161 (3.3%) had complaints of oral aphthous ulcerations, of which 76 (47.2%) were diagnosed as suffering from recurrent aphthous ulcerations and 68 (42.2%) with clinical information necessary for evaluation. The tongue was the most affected anatomical region, with 27 individuals (39.7%), followed by the buccal mucosa, with 22 cases (32.3%). STUDY LIMITATIONS: Retrospective study with data from medical records. CONCLUSION: Dental surgeons, dermatologists and otorhinolaryngologists are the main responsible for the first contact with patients with this disease and should be attentive to the clinical aspects and treat each patient in an individualized way, since the therapy is palliative, its diagnosis is by exclusion and its etiology is unknown.

Introduction: Oral cancer is a public health problem in many countries. However, it is a disease that is preventable because of its well-established association with certain risk factors that can be easily identified by health care professionals during the clinical evaluation of patients. Objective: To analyze the knowledge (real and perceived) that dentists and dental students have regarding the diagnosis of and risk factors for malignant and potentially malignant oral lesions. Method: Data were collected with a previously validated questionnaire, adapted for use in this study, including questions designed to collect sociodemographic data and information about the level of knowledge of potentially malignant oral lesions and oral cancer. According to the score, the level of knowledge was categorized as follows: A (excellent); B (good); C (satisfactory); and D (poor). Results: A total of 292 individuals completed the questionnaire. Most (48.97%) of the respondents were between 20 and 29 years of age, and the majority (62.0%) were female. Younger participants, students, and recent graduates displayed the best knowledge of oral cancer (p=0.000). The clinical aspect that was most commonly associated with oral cancer (by 76.4% of the respondents) was leukoplakia. Although 85.4% of the respondents reported being up to date on the topic of oral cancer, only 12.7% had an A level of knowledge. Conclusion: Overall, the level of knowledge of potentially malignant oral lesions and oral cancer was low. However, younger respondents, students, and recent graduates displayed better knowledge of the topic. Key words: Diagnosis; Risk Factors; Mouth Neoplasms.

ABSTRACT

ABSTRACT Objective: To conduct a retrospective study on a series of cases of PV and BMMP with manifestations in the oral cavity in order to ascertain prevalence, sociodemographic characteristics, diagnostic maneuvers, treatment and follow-up. Methods: This is a retrospective, descriptive study in which clinical data were collected from the medical records of all cases of PV and BMMP registered and diagnosed, between 1995 and 2015, in the Oral Diagnostic Service of the UFRN Department of Dentistry. Results: The mean age of the total sample (n = 36) was 41.64, with females the most frequent (n = 26; 72.22%) and the cheek mucosa being the site most affected (n = 20; 27.40%). Eight patients (22.22%), including 5 cases of PV and 3 BMMP, were clinically reevaluated. All patients exhibited lesions at the time of follow-up. Prednisone (n=7; 87.5%) and clobetasol propionate (n=8, 100%) were the most widely used drugs in the systemic and topical treatment, respectively. The follow-up period ranged from 5 months to 5 years. Conclusion: The clinical profile of patients in this study was similar to that evidenced in the literature. However, it was found that the oral lesions were more resistant to the treatment used on the patients evaluated.


RESUMO Objetivo: Realizar um estudo retrospectivo em uma série de casos de PV e BMMP com manifestações em cavidade oral com o intuito de verificar suas prevalências, características sociodemográficas, diagnóstico, tratamento e acompanhamento. Métodos: Trata-se de um estudo retrospectivo descritivo no qual os dados clínicos foram coletados a partir dos prontuários de todos os casos de PV e BMMP registrados e diagnosticados, entre 1995 e 2015, no serviço de Diagnóstico Oral do Departamento de Odontologia da UFRN. Resultados: Da amostra total (n=36), a age média foi de 41,64 anos, sendo o sexo female o mais frequente (n=26; 72,22%) e a mucosa jugal o sítio mais afetado (n=20; 27,40%). Oito pacientes (22,22%), dos quais 5 são casos de PV e 3 de BMMP, foram reavaliados clinicamente. Todos os pacientes exibiram lesões no momento do acompanhamento, sendo a prednisona (n=7) e o propionato de clobetasol (n=8) os fármacos mais utilizados no tratamento sistêmico e tópico, respectivamente. O tempo de acompanhamento variou de 5 meses a 5 anos. Conclusão: O perfil clínico dos pacientes da presente pesquisa foi semelhante ao da literatura. No entanto, verificou-se que as lesões orais foram mais resistentes ao tratamento empregado nos pacientes avaliados.

ABSTRACT

Resumo O angioleiomioma é uma neoplasia benigna que, a partir da nova classificação da OMS (2013) para os tumores de tecidos moles, deixou de ser considerado um tumor de origem muscular lisa, passando a ser considerado um tumor de origem perivascular. Raramente os angioleiomiomas ocorrem na cavidade oral. A lesão é tratada cirurgicamente, com prognóstico considerado favorável. Este trabalho revisa os casos de angioleiomioma oral relatados na literatura nos últimos 5 anos e descreve esse tumor em um homem de 44 anos que apresentou um nódulo assintomático localizado em lábio superior, com evolução de 6 meses. As hipóteses diagnósticas foram de adenoma pleomórfico e adenoma canalicular. A lesão foi submetida à biópsia e análise histopatológica e imuno-histoquímica (S100, CD34, α-SMA, H-caldesmon e desmina) confirmaram o diagnóstico de angioleiomioma. Destacamos a imuno-histoquímica como um importante método auxiliar no diagnóstico diferencial do angioleiomioma com outras lesões e, principalmente, com o miopericitoma.


Abstract Angioleiomyoma is a benign neoplasm that was considered a tumor of smooth-muscle origin until the most recent (2013) WHO classification of soft tissue tumors, in which it was reclassified as a tumor of perivascular origin. Angioleiomyomas rarely occur in the oral cavity. These lesions are treated surgically with good prognosis. This article presents a review of reports of oral angioleiomyoma in the literature from the last 5 years and describes the case of a 44-year-old man who presented with an asymptomatic nodule in the upper lip that had developed over a 6-month period. Diagnostic hypotheses of pleomorphic adenoma or canalicular adenoma were raised. Biopsy of the lesion, histopathological and immunohistochemical analysis (S100, CD34, H-caldesmon, and desmin) confirmed a diagnosis of angioleiomyoma. It is noteworthy that immunohistochemistry is an important auxiliary method for differential diagnosis of angioleiomyoma from other tumors, particularly myopericytoma.

ABSTRACT

Abstract: We report a 35-year-old mulatto female patient with neurofibromatosis Type 1 who presented with facial asymmetry. The patient had two lesions: florid cemento-osseous dysplasia associated with peripheral giant cell granuloma. She was referred for surgical treatment of the peripheral giant cell granuloma and the florid cemento-osseous dysplasia was treated conservatively by a multidisciplinary team. So far, no changes have been observed in the patient's clinical status. We observed no recurrence of peripheral giant cell granuloma. To the best of our knowledge, the present case is the first report of a patient with neurofibromatosis Type 1 associated with a giant cell lesion and florid cemento-osseous dysplasia.

ABSTRACT

Abstract: The aim of this study was to compare the number of CD57+ natural killer (NK) cells and CD8+ T lymphocytes between periapical granulomas (PGs) and radicular cysts (RCs). Twenty-fives cases of PGs and 25 of RCs were submitted to histological analysis and immunohistochemistry using anti-CD57 and anti-CD8 biomarkers. Positive cells were counted in 10 fields (400× magnification) and the median value was calculated for each case. Statistical tests were used to evaluate differences in the number of CD57+ NK cells and CD8+ T lymphocytes according to type of lesion, intensity of the infiltrate and thickness of the lining epithelium. The number of CD57+ NK cells and CD8+ T lymphocytes was higher in PGs than in RCs (p = 0.129 and p = 0.541, respectively). Comparison of the number of CD57+ NK cells in atrophic and hyperplastic epithelium revealed a larger number of cells in the atrophic epithelium (p = 0.042). A larger number of CD57+ NK cells and CD8+ T lymphocytes were observed in grade III infiltrates compared to grade I/II (p = 0.145 and p = 0.725, respectively). CD8+ T lymphocytes were more prevalent than CD57+ NK cells in most cases when PGs and RCs were analyzed separately or in combination (p < 0.0001). CD57+ NK cells and CD8+ T lymphocytes play a key role in antiviral defense and the presence of these cells supports evidence suggesting the participation of these microorganisms in the pathogenesis of PGs and RCs. The response mediated by CD8+ T lymphocytes was more frequent, indicating greater participation of the adaptive immunity in these chronic lesions.

ABSTRACT

ABSTRACT Objective To evaluate the clinical-pathological profile of patients with minor salivary gland neoplasms. Methods A retrospective study of specific cases diagnosed as benign and malignant tumors of the minor salivary glands was performed. The data were collected from medical records of patients seen at a hospital over a period of 15 years. The sample was made up of 37 cases. For the pathological study, slides containing 5μm thick sections stained with hematoxylin and eosin were used. The data were tabulated using descriptive statistics. Results Malignant neoplasms represented 70.3% of cases. The mucoepidermoid carcinoma was the most common neoplasm (45.9%), followed by pleomorphic adenoma (24.4%). Most patients were female (70.3%), aged between 71 and 80 years. The palate (67.6%) and the retromolar region (10.8%) were the most affected sites. Conclusion Mucoepidermoid carcinoma was the most common tumor in minor salivary glands. These tumors are more common in females aged over 40 years. The palate was the most common affected site.

ABSTRACT

Abstract: Background: The studies found in the literature associate the immunoexpression of hMLH1 and hMSH2 proteins with histologic aspects, but do not correlate it with clinical and epidemiological data. Objective: To evaluate the immunoexpression of hMLH1 and hMSH2 in actinic cheilitis, correlating it with clinical characteristics. Methods: We analyzed 40 cases. Histological and immunohistochemical analyses were performed. The following clinical variables were evaluated: gender, age range, ethnicity, clinical aspect and occupational sunlight exposure. Statistical evaluation included the Student t-test, while the significance level was set at 5%. Results: Greater immunoexpression of hMLH1 and hMSH2 was observed in females, individuals aged over 40, and mixed-race/black patients. Furthermore, the immunoexpression of these proteins was greater in actinic cheilitis with a white-colored appearance and in patients without occupational sunlight exposure. No statistical differences were observed for the variables studied. Conclusion: This study uncovered variations of hMLH1 and hMSH2 protein expression upon evaluation of clinical aspects in actinic cheilitis.

ABSTRACT

ABSTRACT Objective To determine the incidence of potentially malignant oral lesions, and evaluate and correlate their clinical and pathological aspects. Methods The sample consisted of cases clinically diagnosed as oral leukoplakia, oral erythroplakia, erythroleukoplakia, actinic cheilitis, and oral lichen planus treated at a diagnostic center, between May 2012 and July 2013. Statistical tests were conducted adopting a significance level of 5% (p≤0.05). Results Out of 340 patients, 106 (31.2%) had potentially malignant oral lesions; and 61 of these (17.9%) were submitted to biopsy. Actinic cheilitis was the most frequent lesion (37.5%) and the lower lip was the most affected site (49.6%). Among 106 patients in the sample, 48 (45.3%) reported nicotine consumption, 35 (33%) reported alcohol intake and 34 (32.1%) sun exposure while working. When clinical and histopathological diagnoses were compared, oral erythroplakia and atypical ulcer were the lesions that exhibited greater compatibility (100% each). Conclusion In most cases, clinical and histopathological diagnoses were compatible. An association between the occurrence of erythroplakia, leukoplakia and erythroleukoplakia with smoking was observed. Similarly, an association between actinic cheilitis and sun exposure was noted. Erythroleukoplakia presented the highest malignancy grade in this study. Finally, dental surgeons should draw special attention to diagnosis of potentially malignant oral lesions, choose the best management, and control the lesions to avoid their malignant transformation.


RESUMO Objetivo Verificar a incidência das lesões orais potencialmente malignas, e avaliar e correlacionar seus aspectos clínico-patológicos. Métodos A amostra foi composta pelos casos diagnosticados clinicamente como leucoplasia oral, eritroplasia oral, eritroleucoplasia, queilite actínica e líquen plano oral em um serviço de diagnóstico no período entre maio de 2012 e julho de 2013. Foram realizados testes estatísticos adotando-se nível de significância de 5% (p≤0,05). Resultados Dos 340 pacientes examinados, 106 (31,2%) se apresentaram com lesões orais potencialmente malignas; destes, 61 (17,9%) biópsias foram realizadas. A lesão mais frequente foi a queilite actínica (37,5%), e o sítio anatômico mais acometido foi o lábio inferior (49,6%). Entre os 106 pacientes da amostra, 48 (45,3%) relataram consumo de nicotina, 35 (33%) ingeriam bebidas alcoólicas e 34 (32,1%) trabalhavam expostos ao sol. Comparando o diagnóstico clínico com o histopatológico, as lesões que apresentaram maior compatibilidade foram a eritroplasia oral e a lesão ulcerada atípica (100% ambas). Conclusão Na maioria dos casos, houve compatibilidade do diagnóstico clínico com o histopatológico. Notou-se correlação entre a ocorrência de eritroplasia, leucoplasia e eritroleucoplasia com o hábito de fumar, e entre a queilite actínica com a exposição solar. A eritroleucoplasia foi a lesão que demonstrou maior grau de malignização neste estudo. Diante do exposto, recomenda-se maior atenção por parte dos cirurgiões-dentistas ao diagnóstico das lesões orais potencialmente malignas, para aplicação da melhor conduta e controle da lesão, impedindo sua transformação maligna.

ABSTRACT

A doença das mãos, pés e boca (DMPB) é altamente infecciosa, incomum em adultos e geralmente se apresenta com uma estomatite dolorosa. Nós descrevemos um caso raro de DMPB em uma mulher de 34 anos de idade, com história clínica de infecção intestinal recente e artrite sistêmica com manifestação oral e em mãos. Além disso, discutimos o diagnóstico e tratamento desta doença reforçando a importância do diagnóstico correto, uma vez que o diagnóstico tardio pode ocasionar a propagação da doença


Hand-foot-mouth disease (HFMD) is a highly infectious disease, rare in adults which usually presents a painfull stomatitis. We describe a rare case of HFMD in a 34-year-old woman with medical history of recent intestinal infection and systemic arthritis with only oral and hands involvement. Additionally, we discuss diagnosis and treatment of this disease and reinforce the importance of the correct diagnosis because delayed diagnosis can cause spread of the disease

ABSTRACT

As doenças auto-imunes envolvem a formação de auto-anticorpos direcionados contra alguns elementos teciduais, particularmente os da pele ou superfícies das mucosas, como forma sistêmica. Dentre estas doenças podemos destacar o pênfigo vulgar, o lúpus eritematoso sistêmico e o penfigóide das membranas mucosas. Estas estão, muitas vezes, associadas com sintomas bucais, podendo apresentar em diversos sítios orais a presença de lesões vesículo-bolhosas e gengivite descamativa. Baseado nisto, este artigo realizou uma revisão de literatura que teve como objetivo associar as manifestações periodontais ao pênfigo vulgar, lúpus eritematoso sistêmico e penfigóide das membranas mucosas com o intuito fornecer aos profissionais um melhor entendimento sobre essas doenças, de modo que eles sejam capazes de oferecer um atendimento clínico mais adequado para estes pacientes. Os resultados puderam mostrar que há uma associação dessas doenças auto-imunes a manifestações periodontais, especialmente a gengivite descamativa. Além disso, a literatura as associa à perda óssea alveolar, ao aumento do sangramento gengival, a perda de inserção e a outras desordens periodontais.

ABSTRACT

AbstractBACKGROUND:Actinic cheilitis (AC) is a potentially malignant disorder of the lip caused by chronic exposure to ultraviolet radiation from the sun.OBJECTIVES:To evaluate the clinical, demographic, morphological and therapeutic management in AC cases data associating to the histopathological grading.METHODS:Demographic, clinical and management data of 161 patients with AC were analyzed. In biopsied cases, two calibrated examiners performed histopathological grading by binary system.RESULTS:There was a prevalence of males (79.5%), aged 40 years or older (77.5%), light-skinned (85.7%), experiencing occupational exposure to sunlight (80.3%), with AC presenting clinically as white lesions (33.6%). Conservative treatment was adopted in 78 cases and biopsy in 83 cases (60.2% graded as low-risk AC). There were no significant associations between histopathological grading and gender (p= 0.509), age (p=0.416), ethnicity (p=0.388), occupational exposure to sunlight (p=1.000) or clinical presentation (p=0.803).CONCLUSION:This study reinforces the hypothesis that demographic and clinical characteristics of AC are not related to histopathological grading. Advice on protection from sun exposure should be encouraged to avoid progression of AC and invasive therapies.

ABSTRACT

Objective: This research aims to establish the prevalence, factors associated with the onset, and clinical and histopathological features of oral leukoplakia and erythroplakia, so that these data can contribute to the prevention of these lesions and, consequently, of oral cancer. Material and method: A retrospective study was conducted at a reference service of Universidade Federal do Rio Grande do Norte (UFRN) from 2000 to 2012. To verify the association of variables, Pearson's chi-squared test and Fisher's exact test (p ≤ 0.05) were used. Results: Among 6,560 investigated records, 54 cases were selected, of which 44.4% were male and 55.6% female, with mean age of 56.93 years. Regarding habits, 72.2% were smokers and 25% were alcohol users; 17.9% showed association of both habits. Oral leukoplakia lesions were the most prevalent (0.65%) and oral erythroplakia showed greater association with malignancy in the histopathological presentation (p = 0.001). Most lesions showed no symptoms (p = 0.004). The most frequent was oral leukoplakia in smoking women, with mean age of 57 years. Conclusion: Knowledge of associated factors and clinical characteristics of oral leukoplakia and erythroplakia is essential for establishing the correct diagnosis and treatment...


Objetivo: Esta pesquisa objetiva estabelecer a prevalência, os fatores associados ao surgimento e as características clínicas e histopatológicas das leucoplasias e eritroplasias orais, a fim de que estes dados possam contribuir na estratégia de prevenção ao desenvolvimento dessas lesões e, consequentemente, do câncer oral. Material e método: Foi realizado estudo retrospectivo em um serviço de referência da Universidade Federal do Rio Grande do Norte (UFRN) no período de 2000 a 2012. Para verificar a associação das variáveis foi utilizado o teste qui-quadrado e o exato de Fisher (p ≤ 0,05). Resultados: Foram investigados 6.560 prontuários, tendo sido selecionados 54 casos, dos quais 44,4% do sexo masculino e 55,6% do feminino, com idade média de 56,93 anos. Com relação aos hábitos, 72,2% eram fumantes e 25% usuários de álcool, sendo que 17,9% exibiam associação dos dois hábitos. As leucoplasias orais foram as lesões mais prevalentes (0,65%), e as eritroplasias orais apresentaram maior associação com apresentação maligna no diagnóstico histopatológico (p = 0,001). A maioria das lesões não apresentou sintomatologia (p = 0,004). A leucoplasia oral foi mais frequente em mulheres fumantes com média de idade de 57 anos. Conclusão: O conhecimento dos fatores associados e das características clínicas das eritroplasias e leucoplasias orais é essencial para o estabelecimento do correto diagnóstico e tratamento...

ABSTRACT

Subjects were selected from five urban beaches to characterize the type of work conducted on urban beaches in the city of Natal, state of Rio Grande do Norte, Brazil, and determine potential associated factors among workers exposed to the sun. Data collection was based on a validated questionnaire. Results were obtained for 362 workers. Individuals were predominantly male (72.6%) who worked under direct exposure to the sun (87.8%). Almost 95% had no more than 6 years of schooling and 87.91% earned an average monthly income of $318.75 dollars or more. Photoprotection was reported by 80.1%, among which sunscreen and caps/hats were predominant. Around 25% smoked and more than half did not consume alcohol. Male gender, no more than 6 years of schooling, daily exposure for up to 6 hours and use of photoprotection were the factors associated with the outdoor work category.
