Objective Analyze the epidemiological profile and the specific survival of patients diagnosed with tongue squamous cell carcinoma at the National Cancer Institute (INCA). Materials and methods Hospital Cancer Registry System Data and Mortality Information from 2007 to 2009 were retrieved in a retrospective cohort study of patients diagnosed with tongue squamous cell carcinoma. Specific survival was estimated using the Kaplan-Meier method. The association between independent variables and the risk of death was explored in a Cox proportional hazards regression model. Results A total of 346 patients were eligible, mostly male (77.5%), smokers (87.6%), with alcohol consumption (80.9%), with low education (65.6%), advanced staging at the time of diagnosis (71.1%) and presenting a high mortality rate (72.5%). In total, 44.5% of patients underwent a surgical approach alone or associated with another treatment modality, of which 85.1% of patients underwent neck dissection and 90.1% had free surgical margins. Specific survival was 40.6% in two years and 31.2% in five years. Conclusion The 5-year specific survival was considered worse in individuals over 60 years, and who did not undergo surgical treatment or had surgery associated with another treatment, compared to patients undergoing isolated surgery.

Introdução: Os Programas de Residência Multiprofissional constituem-se uma estratégia fundamental para a ampliação da capacidade para o enfrentamento do câncer. Objetivo: Analisar o panorama atual dos Programas de Residência Multiprofissional em Oncologia para cirurgiões-dentistas no Brasil, bem como o número de profissionais egressos desses cursos, a partir de dados informados pelo Ministério da Educação (MEC). Método: Trata-se de um estudo quantitativo, exploratório. A primeira fase consistiu na solicitação à Equipe Técnica da Residência Multiprofissional do MEC do Brasil da relação de todos os Programas de Residência Multiprofissional em Oncologia que incluíssem a categoria profissional da odontologia. Adicionalmente, foi realizada busca manual. Na segunda fase, realizaram-se contato por e-mail e busca pelos editais disponíveis na Internet dos casos em que não houve resposta. Os dados investigados foram a presença de Programa ativo, inclusão da categoria profissional da odontologia, número de vagas ofertadas e de egressos para cada ano entre 2010 e 2020, que foram analisados descritivamente. Resultados: Foram identificados 13 Programas de Residência Multiprofissional em Oncologia para cirurgiões-dentistas, distribuídos em 12 centros, situados em dez cidades de oito Estados brasileiros, sobretudo, na Região Sudeste. Seis Programas foram implementados em 2010, seis em 2016 e um em 2020. No cenário Brasileiro, entre 2010 e 2020, foram ofertadas 216 vagas e formados pouco mais de 114 profissionais especializados nessa área. Conclusão: Ressalta-se a necessidade do incremento de centros, Programas e vagas para Residências Multiprofissionais em Oncologia para cirurgiões-dentistas no Brasil, bem como do reconhecimento da Oncologia como uma especialidade odontológica.

Introdução: A doença do enxerto contra o hospedeiro crônica (DECHc) é a principal causa de morbimortalidade após o transplante alogênico de células-tronco hematopoiéticas (TCTH-alo). Relato do Caso: Acompanhamento odontológico de paciente do sexo masculino, 59 anos, com diagnóstico inicial de leucemia mieloide aguda, submetido ao TCTH-alo em maio de 2017. No D+ 224, o paciente evoluiu para um quadro de DECHc acometendo a pele, a cavidade oral e o trato gastrointestinal, porém com dentes ainda hígidos. No D+ 392, o paciente queixou-se de boca seca, e foram observadas lesões orais, sialometria de 0,024 mL/min e evolução de lesões cariosas nos dentes 17, 15, 22, 25, 27, 38, 45 e 46. No D+ 560, o paciente ainda estava com DECHc oral e houve progressão das cáries em inúmeros dentes. Tratamento e Resultados: O manejo terapêutico adotado consistiu na utilização de diamino fluoreto de prata pela propriedade cariostática com redução da odontalgia e, posteriormente, foram realizadas as restaurações dentárias. Além disso, o paciente foi orientado em relação à dieta, à manutenção da higiene oral e ao uso de lubrificante oral na tentativa de amenizar a xerostomia. Conclusão: Observou-se, neste caso clínico, que o diamino fluoreto de prata foi eficaz no controle da evolução da cárie e redução da odontalgia no paciente adulto. É evidente a importância da capacitação dos cirurgiões-dentistas no que diz respeito ao conhecimento sobre a utilização de cariostáticos em pacientes com alterações na qualidade e quantidade de saliva como os pacientes com DECHc oral.

Objective The aim of this systematic review was to describe the epidemiology, diagnostic criteria, differential diagnosis, treatment, prognostic factors, and treatment outcomes of secretory carcinoma. Study Design A comprehensive search of Lilacs, PubMed, Science Direct, and Web of Science databases was conducted to identify all case reports, letter to the editor, and histopathologic reclassifications regarding salivary gland secretory carcinoma published in English, Spanish, French, and Portuguese. Results The final analysis included 119 studies, which totaled 642 secretory carcinoma diagnoses, with 239 case reports and 403 diagnostic reclassifications, mostly in the United States. The age range was 5 to 87 years, and cases were predominantly in males (58.7%) and mostly affecting the parotid glands (73.7%). The disease usually presents as a slow-growing, painless mass. The main differential diagnosis is acinic cell carcinoma, and the tumor is usually treated with surgery. The prognosis is considered favorable, although there have been reports of local recurrences, distant metastases, and deaths. Conclusions It is important that clinicians become aware of this salivary gland neoplasm and report clinical data, clinical course, management and long-term follow-up. There is an urgent need to conduct more clinical trials, especially on tropomyosin receptor kinase (TRK) inhibitors and other potential target therapy modalities.

Mucosal melanomas are primary malignant neoplasias originated from melanocytes within mucous membranes in any part of mucosal surface lining, more commonly, in the nasal cavity and accessory sinuses, oral cavity, lips, pharynx, vulvar, vaginal, cervix and anorectal mucosa. Epidemiology data regarding mucosal melanomas in Brazil is scarce, hence the motivation to conduct this research paper. The χ2 test was used to compare categorical variables. Forward stepwise logistic regression method was used in the multivariate analysis to identify independent predictors of early death. A total of 801 patients were included in the analysis. Surgical resection is frequently the first approach to primary tumours (65.3%), even though the utility of lymph node surgery and radiation therapy is not well established. Advanced stage was observed in more than two thirds of patients. Early death was observed in 28.3%. MM cases with regional or distant metastases as well as those located in unusual locations had almost 4 times more risk for early death. Besides that, MM located in lips, oral cavity and pharynx and those receiving chemotherapy had 2 times more risk of early death.

Objectives This study aim was to review cases of acinic cell carcinoma (the main differential diagnosis of secretory carcinoma) that were diagnosed and treated at the National Cancer Institute of Brazil (INCA) between 1996 and 2016. The primary objective was to identify underdiagnosed cases of secretory carcinoma via a clinical, immunopathological and molecular reassessment. Materials and methods This is a cross sectional study, with retrospective data collection from medical records and histological specimen review, with staining for periodic acid-Schiff (PAS) and PAS with diastase, immunohistochemistry for S-100, mammaglobin, and DOG-1, and droplet digital RT-PCR for ETV6-NTRK3. The Research Ethics Committee approved this study, and the patients allowed their participation through informed consent. Results Eighty-three cases of acinic cell carcinoma were diagnosed and treated in the specified period at INCA, of which, seven had their diagnosis changed to secretory carcinoma. Conclusion The present study adds seven cases of secretory carcinoma to the literature, contributing to a better understanding of the epidemiological, histological, immunohistochemical and molecular characteristics of this recently described tumor. Also, the use of a comprehensive diagnostic approach, including immunohistochemical and molecular methods, along with classical morphological studies, allowed the reclassification of acinic cell carcinoma to secretory carcinoma.

Paracoccidioidomycosis is the most prevalent systemic mycosis in Latin America. It is a fungal infection caused by the dimorphic fungus Paracoccidioides brasiliensis. This microorganism can penetrate the human body through direct contact and can cause intense lymphadenopathy, ulcerated lesions in the oral cavity and in the skin among other alterations. In this study, we report a case of paracoccidioidomycosis with unusual clinical presentation, as it manifested in the female sex and although it did not present any relevant complaints of respiratory focus, it presented a single ulcerated lesion in the buccal mucosa. A biopsy of the lesion and a mycological examination revealed Paracoccidioidesbrasiliensis infection.

This chapter highlights the effect of coffee extracts on oral diseases, particularly dental caries and periodontitis. Both diseases still present high prevalence worldwide and are considered biofilm-related disorders. In this context, taking into account the antimicrobial resistance in bacterial populations, natural forms of antimicrobial therapy have been overlooked in the literature, especially due to its safe use in comparison to the synthetic manufactured chemical compounds. Some aqueous extracts of coffee were reported to present antibacterial activity against microorganisms from the oral cavity and for this reason have been demonstrated to present anticariogenic effect. In a similar way, periodontopathogenic microorganisms seem to be susceptible to the antimicrobial effects of coffee, presenting a beneficial role in periodontal tissue protection and in periodontitis. This chapter will discuss how the benefits of coffee on these two oral diseases take place.

Background The purpose of this current research was to clarify for the scientific community the trends of tongue cancer epidemiology in Brazil. Methods The data came from Population Based Cancer Registries, Hospital Cancer Registries, and Mortality Information System from 2000 to 2014. Results The age-adjusted incidence rate are increasing in both men and women for base of tongue cancer and for other and unspecified parts of the tongue in women, and decreasing in men for other and unspecified parts of the tongue. The majority of cases were diagnosed at clinical stages III and IV. The mortality rate remained relatively stable in both men and women in the period studied. Conclusion The increase in age-adjusted incidence rate for tongue cancers (except for other and unspecified parts of the tongue in men), with most patients over 50 years of age, with low education levels, and advanced disease reinforces the need for interventions that address access to health promotion resources and medical care in Brazil.

Oral leukoplakia is the most common lesion with malignant potential that may occur in the oral cavity. A white 60-year-old woman who never smoked or ingested alcoholic beverage presented with the diagnosis of a right infiltrating lobular carcinoma of the breast on May 18, 2009, and suspicion of an oral leukoplakia with 10 years of evolution. After an incisional biopsy, a well-differentiated superficially invasive squamous cell carcinoma was revealed approximately 1 week later. Subsequently, on August 17, 2010, a partial glossectomy was performed, and 6 months later a second incisional biopsy with a negative malignancy report was carried out. The patient is under control with no sequelae and no evidence of active disease. Early diagnosis of oral cancer through stomatologic screening of precursor epithelial lesions such as leukoplakia minimizes sequelae resulting from late diagnosis, improving not only quality of life but also patient survival rate.

Secretory carcinoma, described as mammary analog secretory carcinoma, is a recently described tumor of salivary glands that is defined by its histologic, immunophenotypic, and genetic similarities to the secretory breast carcinoma and is characterized by ETV6 translocation. The first description of mammary analog secretory carcinoma was reported by Skalova et al. in 2010. Retrospective studies showed that some tumors of salivary glands such as acinic cell carcinoma, low-grade salivary duct carcinoma, adenocarcinoma/cystadenocarcinoma not otherwise specified (NOS), and low-grade mucoepidermoid carcinoma were misdiagnosed. The purpose of this study is to review the literature showing the differential characteristics among these tumors and secretory carcinoma, highlighting how to perform the correct diagnosis, giving the patients the right treatment and improving their prognosis. Potential target therapy is also approached.

Viruses are the major contributors to the morbidity and mortality of upper and lower acute respiratory infections (ARIs) for all age groups. The aim of this study was to determine the frequencies for a large range of respiratory viruses using a sensitive molecular detection technique in specimens from outpatients of all ages with ARIs. Nasopharyngeal aspirates were obtained from 162 individuals between August 2007-August 2009. Twenty-three pathogenic respiratory agents, 18 respiratory viruses and five bacteria were investigated using multiplex real-time reverse transcriptase polymerase chain reaction (RT-PCR) and indirect immunofluorescence assay (IIF). Through IIF, 33 (20.4%) specimens with respiratory virus were recognised, with influenza virus representing over half of the positive samples. Through a multiplex real-time RT-PCR assay, 88 (54.3%) positive samples were detected; the most prevalent respiratory viral pathogens were influenza, human rhinovirus and respiratory syncytial virus (RSV). Six cases of viral co-detection were observed, mainly involving RSV. The use of multiplex real-time RT-PCR increased the viral detection by 33.9% and revealed a larger number of respiratory viruses implicated in ARI cases, including the most recently described respiratory viruses [human bocavirus, human metapneumovirus, influenza A (H1N1) pdm09 virus, human coronavirus (HCoV) NL63 and HCoV HKU1].

Background: Basosquamous carcinoma (BSC) is a rare non-melanoma skin cancer, considered to be a subtype of basal cell carcinoma (BCC). BSC often produces distant metastases with a higher risk of recurrence than that of BCC which is not commonly found in the lip. Case Report: A 57-year-old white female patient presented an ulcer on her lower lip that had an ongoing development for over six months. Physical examination, photo documentation, videoroscopy, scraped cytology, toluidine blue test, and biopsy of the ulcer were carried out. Results: Upon physical examination we observed an actinic cheilitis associated with the ulcer. Videoroscopy revealed the presence of fissures and erosion that had not been seen by oroscopy. Toluidine blue test was only positive for the region of the ulcer. Cytological analysis revealed rare nests compatible with carcinoma. Histopathology of the biopsy revealed a carcinoma with nests lined by basal cells associated with areas of squamous differentiation. The patient was then referred to surgery for the removal of the BCC. Analysis of the specimen showed free surgical margins and the immunohistochemical panel did not confirm the initial diagnosis of BCC, indicating a subtype of BSC. After surgery, the patient has been followed by periodic consultations. She is well and without further complications. Coments: BSC is considered to be an aggressive and rare tumor affecting mainly upper face and primarily affects men over 60 years of age. Since our patient is a woman presenting the lesion in the lower lip, this highlights the unusual and interesting presentation of this case report.

In order to understand how dentists should act whenapproaching patients that can present with cancer or precancerof the oral cavity, it is adamant that the professionalsfamiliarize themselves with the current trends of oral cancerand potentially malignant disorders. A study conducted onlythree years ago pinpointed that squamous cell carcinomaof the head and neck has a five-year survival rate of only 40to 60% in fifty years, despite advances in surgical techniques,radiotherapy, chemotherapy and combined therapies.1 Inorder to avoid these terrible statistics, a great effort must bemade by medical professionals, especially those thatconstantly examine the oral cavity, also known as: dentists.

Dental biofilm is a complex community of potentially cariogenic oral bacteria that produce acids in the presence of carbohydrates, resulting in a pH reduction, which leads to a loss of minerals from the tooth. Streptococcus mutans is the most commonly isolated species and the primary etiological pathogen associated with the formation of dental caries. The impairment of the growth of this bacteria or ability to adhere to tooth surfaces and be incorporated in the dental biofilm would be of relevance in the fight against tooth decay. Among the natural products capable of inhibiting the growth of cariogenic bacteria and avoiding tooth demineralization is the coffee species Coffea canephora . The anticariogenic effects of this species are mostly derived from its phenolic compounds, caffeine and trigonelline content. This chapter presents current evidence in support of the species C. canephora as a promising natural product that prevents caries disease due to its bioactive ingredients.

Background: Geographic stomatitis is an uncommon oral lesion that presents similar clinical, histopathological and genetic features as those of psoriasis. These findings suggest that this lesion may actually represent an oral manifestation of psoriasis. We report one case of geographic stomatitis and discuss a possible connection between this condition and psoriasis.

We describe the first report of simultaneous blood infection with KPC-2 producing Klebsiella pneumoniae and Escherichia coli in a Brazilian patient. We highlight the importance of implementing efficient infection control measures to limit the spread of these phenotypes in a hospital setting.

SUMMARY Erysipelatoid Carcinoma (EC), also known as Inflammatory Metastatic Carcinoma, is a rare form of cutaneous metastasis, secondary to an internal malignancy, more often related to breast cancer. Clinically, the lesion has a well-marked, bound erythematous appearance, much like an infectious process, such as erysipelas and cellulitis, these being the most common differential diagnoses. It is characterized by an acute or subacute appearance with an erythematous plaque, sometimes hot and painful, being more often situated in the primary tumor vicinity, especially in the thorax wall in the region of a mastectomy due to breast cancer. Here we present the case of a 75-year-old patient with ductal infiltrated carcinoma for 3 years, who presented an acute erythematous and infiltrated plaque in the region of a previous mastectomy, with a final diagnosis of EC.
