ABSTRACT

BACKGROUND: Human T-lymphotropic virus type I (HTLV-I) is known to be associated with neoplastic and neurodegenerative changes, and it is believed to be associated with various systemic inflammatory diseases, including Sjögren's syndrome (SS). Although HTLV-I infection is endemic in Brazil, there is no information regarding the association between HTLV-I infection and SS in the Brazilian population. The objective of this study was to determine the prevalence of SS in HTLV-I-infected individuals and the prevalence of HTLV-I infection in individuals diagnosed with SS. METHODS: Serology for HTLV-I was performed in 50 patients presenting with complaints consistent with SS (the SS group). The HTLV-I group comprised 129 HTLV-I-infected patients who were screened for SS. RESULTS: None of the patients in the SS group tested positive for HTLV-I. Of the 129 patients in the HTLV-I group, 46 (35.7%) had xerostomia, 18 (13.95%) had xerophthalmia, eight (6.2%) had hyposalivation, two (1.55%) showed impaired tear secretion, and one (0.77%) was positive for autoantibodies (anti-SSB). In addition, six underwent minor salivary gland biopsy, and the histopathological findings were consistent with SS. Only two (1.55%) met the diagnostic criteria for SS. CONCLUSIONS: The prevalence of SS was found to be three times as high in HTLV-I-infected individuals as it was in those without HTLV-I infection. However, given the small number of HTLV-seropositive patients with SS, it is impossible to state that HTLV acts as an immune-activating pathogen for SS.

ABSTRACT

ABSTRACT INTRODUCTION: Many epidemiological studies have suggested that human papillomavirus (HPV), especially type 16, is involved in the genesis of squamous cell carcinoma of the oral cavity and oropharynx, especially in young, non-smoking patients; thus, its detection in lesions in this region is important. OBJECTIVE: To clarify the capacity of the brushing sampling method to detect the presence of HPV in oral or oropharyngeal lesions through polymerase chain reaction (PCR) testing, and to compare the results with those obtained by biopsy. METHODS: Prospective study of adult patients with oral or oropharyngeal lesions assessed by PCR, comparing biopsy specimens with samples obtained by the brushing method. The study was approved by the Research Ethics Committee of the institution. RESULTS: A total of 35 sample pairs were analyzed, but 45.7% of the brushing samples were inadequate (16/35) and, thus, only 19 pairs could be compared. There was agreement of results in 94.7% (18/19) of the pairs, with HPV identified in 16 of them. HPV DNA was detected in 8.6% (3/35) of biopsy and 5.7% (2/35) of brushing samples. CONCLUSION: There was no statistically significant difference between the two methods, but the brushing sampling method showed a higher number of inadequate samples, suggesting that it is an unreliable method for surveillance.


Resumo INTRODUÇÃO: Muitos estudos epidemiológicos indicam a participação do papilomavírus humano, especialmente o tipo 16, na carcinogênese dos tumores espinocelulares das cavidade oral e oro-faríngea, principalmente em jovens e não fumantes, sendo portanto importante sua detecção nas lesões desta região. OBJETIVO: Elucidar a habilidade do escovado em detectar o papilomavírus humano, pela reação em cadeia da polimerase, nas lesões orais e orofaríngeas, comparando os resultados com os obtidos por biópsia. MÉTODO: Estudo prospectivo de pacientes com lesões orais e orofaríngeas, pela reação em cadeia da polimerase, no qual foram pareados os resultados de amostras obtidas por escovado e por biópsia. A pesquisa foi aprovada pelo Comitê de Ética em Pesquisa da instituição. RESULTADO: Foram analisados 35 pares de amostras, porém estavam inapropriadas para análise 45,7% (16/35) das amostras obtidas por escovado, e portanto, somente 19 pares puderam ser comparados. Em 94,7% dos pares houve concordância dos resultados, sendo encontrado o papilomavírus humano − 16 em um destes pares. O ácido desoxirribonucleico do papilomavírus humano foi detectado em 8,6% (3/35) das biópsias e em 5,7% (2/35) dos escovados. CONCLUSÃO: Não houve diferença estatística entre os métodos, mas como houve um grande número de amostras obtidas por escovado inapropriadas, este parece não ser confiável para o rastreamento.

ABSTRACT

INTRODUCTION: Saliva plays a key role in the homeostasis of the digestive tract, through its inorganic components and its protein growth factors. Sjögren's syndrome patients have a higher prevalence of gastroesophageal reflux disease and laryngopharyngeal reflux. Decreased salivary transforming growth factor alpha levels were observed in dyspeptic patients, but there have been no studies in patients with Sjögren's syndrome and laryngopharyngeal reflux. OBJECTIVE: To compare the salivary transforming growth factor alpha levels of patients with Sjögren's syndrome and laryngopharyngeal reflux to those of healthy controls. METHODS: This is a prospective controlled study. Twelve patients with Sjögren's syndrome and laryngopharyngeal reflux and 11 controls were prospectively evaluated. Spontaneous and stimulated saliva samples were obtained to establish salivary transforming growth factor alpha concentrations. RESULTS: The salivary transforming growth factor alpha levels of patients were significantly higher than those of healthy controls. Five patients with laryngopharyngeal reflux also had erosive esophagitis; their salivary transforming growth factor alpha levels were comparable to controls. CONCLUSION: Salivary transforming growth factor alpha level was significantly higher in patients with Sjögren's syndrome and laryngopharyngeal reflux when compared to the control group.

Introdução: A saliva exerce influência primordial na homeostase do sistema digestório, pelos seus componentes inorgânicos e pelos fatores de crescimento. Indivíduos com sindrome de Sjögren (SS) apresentam maior incidência da doença do refluxo gastroesofágico (DRGE) e do refluxo laringofaríngeo (RLF). Concentrações salivares diminuídas do fator transformador de crescimento alfa (TGF-α) foram observadas em doentes dispépticos, porém não há estudos em populações com SS e RLF. Objetivo: Comparar concentrações salivares do TGF-α; de indivíduos com SS e RLF a de controles saudáveis. Método: Trata-se de um estudo prospectivo controlado. Doze pacientes com SS e RLF e 11 indivíduos controles saudáveis tiveram amostras salivares espontâneas e estimuladas coletadas para estabelecer concentração de TGF-α. Resultados: A concentração salivar de TGF-α; foi estatisticamente maior no grupo estudo para ambas amostras. Este aumento foi confirmado nos sete indivíduos do grupo estudo que não apresentavam esofagite erosiva quando comparados ao grupo controle, porém não houve diferença estatística da concentração de TGF-α; entre pacientes do grupo estudo que apresentava mesofagite erosiva em comparação ao grupo controle. Conclusão: A concentração salivar de TGF-α; foi estatisticamente maior no grupo de indivíduos com SS e RLF, sem esofagite erosiva. .

ABSTRACT

UNLABELLED: Parotid gland parenchyma histology may be altered by local or systemic, pathological or nonpathological conditions. OBJECTIVE: This paper aims to highlight the fatty degeneration of the parotid gland, a not well-known non-pathological condition. METHOD: In a retrospective study, we collected a series of 6 patients which presented a swelling of the parotid, but even after extensive research, a diagnosis was not reached. RESULTS: Through the retrospective analysis of records we found fatty degeneration of the parotid in an MRI scan of all patients. CONCLUSION: This condition, despite being physiological and expected with aging, may be related to clinical and radiological swelling of these glands.

ABSTRACT

A histologia do parênquima das glândulas parótidas pode estar alterada por condições locais ou sistêmicas, patológicas ou não patológicas. OBJETIVO: Este trabalho objetiva destacar a lipossubstituição das parótidas, uma condição não patológica pouco conhecida. MÉTODO: Em um estudo retrospectivo, reuniu-se a casuística de seis pacientes que se apresentaram clinicamente com aumento de volume das parótidas, mas que, após ampla investigação, não se chegou a um diagnóstico. RESULTADOS: Por meio da análise retrospectiva de seus prontuários, foi constatada, em todos, lipossubstituição das parótidas, em estudo de ressonância magnética. CONCLUSÃO: Essa condição, apesar de fisiológica e esperada com o envelhecimento, pode relacionar-se com o aumento clínico e radiológico dessas glândulas.

ABSTRACT

UNLABELLED: The human papillomavirus (HPV) is a DNA virus, which belongs to papillomaviridae family, being of low and high risk, which infect the skin and mucous membranes and can induce benign and malign tumor formation. In the oral mucosa they have been associated with oral papilloma, focal epithelial hyperplasia, leucoplakia and oral neoplasia. AIM: to study the frequency of HPV finding in oral mucosa of normal people. MATERIALS AND METHODS: Prospective study, cross-sectional cohort. One hundred volunteers, young adults, healthy, aged between 20 and 31 years, university students with no history, no complains, without oral or oropharyngeal lesions. They were submitted to a questionnaire with questions regarding HPV infection epidemiology. The samples were harvested by brushing and analyzed by PCR. RESULTS: The results were negative for HPV in all samples. CONCLUSION: It seems we had high social and economical class individuals, with nutrition rich in carotenoyds and vitamin C, low smoking and alcohol consumption and heterosexual habits with predominant monogamy and regular use of condoms.

ABSTRACT

Os papilomavírus humanos (HPV) são DNA vírus pertencentes à família papilomaviridae com grupos de baixo e alto risco que infectam a pele e a mucosa podendo induzir a formação de tumores epiteliais benignos e malignos. Na mucosa oral, estes vírus têm sido associados a papilomas orais, hiperplasias epiteliais focais, leucoplasias e neoplasias orais. Objetivo: Estudar a frequência do HPV em mucosa oral de indivíduos normais. Material e método: Trabalho prospectivo em coorte transversal. Participaram desse estudo 100 indivíduos voluntários, faixa etária de 20 a 31 anos, estudantes universitários, sem história, queixas ou lesões visíveis ao exame físico de cavidade oral e orofaringe. Foram submetidos a questionário com perguntas referentes à epidemiologia da infecção pelo HPV. Foi colhido material de mucosa oral por raspado com escova e analisado pelo PCR. Resultados: Os resultados mostraram ausência de HPV em todas as amostras. Conclusão: Parece ter havido participação do alto nível socioeconômico com alimentação rica em carotenoides e vitamina C, baixo consumo tabágico e etílico e comportamento heterossexual predominantemente monogâmico com uso regular de preservativos.

ABSTRACT

OBJECTIVE: The aim of the present study was to determine the prevalence of concurrent oral and anogenital human papillomavirus (HPV) infection in male patients using polymerase chain reaction and reverse hybridization. STUDY DESIGN: Thirty consecutive men were recruited among those attending the Clinic for Sexually Transmitted Diseases of the Outpatient Department of Dermatology and Sexually Transmitted Diseases, Santa Casa Hospital, São Paulo. The criteria for enrollment in the study were: age between 15 and 60 years, negative human immunodeficiency virus (HIV) status, and the presence of HPV anogenital lesion(s) confirmed by polymerase chain reaction and reverse hybridization. As a part of their management, all patients were subjected to punch biopsy of the anogenital lesions to confirm HPV and an HIV blood test to ensure that they were HIV negative. All patients had their oral mucosa examined with an artificial light. All oral lesions were sampled by biopsy, and subjects with no detectable lesions were sampled by oral mucosal scraping for HPV testing by polymerase chain reaction and reverse hybridization. All patients also completed a questionnaire that recorded their sexual preferences (heterosexual or homosexual, monogamous or polygamous), frequency of sexual activity, practice of oral and/or anal sex, and the use of condoms. RESULTS: Only 3 patients presented with a clinically detectable oral lesion. Among them, just 1 was HPV positive by the molecular assay. In all of the other patients (27 out of 30), oral clinical lesions were not detected and scrapings were all negative for HPV infection. CONCLUSION: The prevalence of concurrent oral and anogenital HPV infection was very low in this study (1 out of 30).

ABSTRACT

UNLABELLED: Infection by the Human Papilloma Virus (HPV) is one of the most frequent sexually transmitted diseases all over the world. The relationship between oral and genital HPV remains uncertain, as it is with its role on oral carcinogenesis. The goal of the present investigation was to check for the presence of HPV DNA in the oral and genital mucosas of women with HPV genital infection, using the polymerase chain reaction (PCR). STUDY METHOD: Cross-sectional cohort. MATERIALS AND METHODS: This is a pilot and prospective study involving 30 women, aged between 14 and 51 years, with HPV genital infection, confirmed by histopathology. All the patients were submitted to the exam and sample collection by swabbing the oral and genital mucosas in order to test for HPV DNA through the PCR technique. RESULTS: None of the oral cavity samples were positive for HPV, while in the genital tract, HPV was detected in 17 (57%) of the 30 patients, especially HPVs 6b and 16. CONCLUSION: Results show a higher percentage of genital HPV in comparison to the oral cavity, and suggest that genital HPV does not seem to be a predisposing factor for the oral infection in the same patient.

FORMA DE ESTUDO: Coorte transversal. MATERIAL E MÉTODO: Trata-se de um estudo piloto, prospectivo, com 30 mulheres, idade de 14 a 51 anos, portadoras de infecção genital por HPV confirmada pelo exame de histopatológico. Todas as pacientes foram submetidas a exame e coleta por raspagem da cavidade oral e genital para pesquisa do DNA do HPV pela técnica PCR. RESULTADOS: Nenhuma das amostras da cavidade oral foi positiva para HPV, enquanto no genital, o HPV foi detectado em 17 (57 por cento) das 30 pacientes, principalmente o HPV 6b e 16. CONCLUSÃO: Os resultados mostraram maior porcentagem do HPV genital em relação à cavidade oral, e sugerem que o HPV genital não parece ser fator predisponente para a infecção oral no mesmo paciente.

ABSTRACT

The prevalence of human papillomavirus (HPV) in the oral cavity and oropharynx has not yet been as well studied as its infection of the vaginal tract. However, new study are emerge after the development of molecular biology techniques. The objective of this study is to show the prevalence of HPV in the oral cavity and the oropharynx. An ample bibliographic review was done showing a prevalence of HPV 6, 11 in a normal oral mucous membrane (latent infection). In oral benign lesions associated with HPV, a prevalence of HPV 6 and 11 was observed in squamous cell papilloma (SCP) and condylomas acuminatum, while HPV 2 and 57 were more prevalent in verruca vulgaris lesions. As for focal epithelial hyperplasia (FEH) and oral cancer, especially squamous cell carcinoma (SCC), the prevalence was of HPV 13 and 32, and HPV 16, respectively. The last findings are, nonetheless, controversial. The last findings are, nonetheless, controversial. Showed also discrepancy result the prevalence of human papillomavirus (HPV) in normal oral mucous (latent infection) and in oral cancer, however evidenced confirmatory result in oral benign lesions associated with virus.

ABSTRACT

INTRODUCTION: Many diagnostic tests are used to evaluate dry mouth patients, especially the ones with Sjögren's Syndrome, to whom these tests are part of classification criteria for scientific studies. AIM: Thus, the concordance between results of sialometry and salivary glands scintigraphy was evaluated; if positive, it would enable the choice of one or the other for diagnosis. PATIENTS AND METHOD: Seventy-two dry mouth patients were divided into non-Sjögren's Syndrome group, primary Sjögren's Syndrome group and secondary Sjögren's Syndrome group. The concordance among sialometry and scintigraphy results was evaluated by Kappa test. RESULTS: It was observed that their concordance was equal or near to zero. CONCLUSION: It is not possible to make a choice between these tests and both should be performed.

ABSTRACT

A prevalência do papilomavírus humano (HPV) na cavidade oral e na orofaringe ainda não está bem esclarecida como nos estudos do trato genital, na qual é bem definida. Entretanto, novas pesquisas estão surgindo após o aparecimento dos exames de biologia molecular. Neste estudo foi realizada uma revisão da literatura com o objetivo de verificar a prevalência do papilomavírus humano na cavidade oral e na orofaringe. Os resultados desta pesquisa mostraram uma prevalência do HPV 16 na mucosa oral normal (infecção latente). Já nas lesões benignas orais associadas ao HPV mostraram uma prevalência do HPV 6 e 11 em papilomas de células escamosas e condilomas, e, nas verrugas, uma prevalência do HPV 2 e 57, enquanto na hiperplasia epitelial focal prevaleceram os HPVs 13 e 32, e no câncer oral, principalmente, no carcinoma de células escamosas (CCE), foi evidenciada uma alta prevalência do HPV 16, o que sugere sua participação na carcinogênese oral, apesar de ser um assunto controverso. Constatou-se também uma enorme discrepância nos resultados da prevalência do papilomavírus humano (HPV) na mucosa oral normal (infecção latente) e no câncer oral, enquanto nas lesões benignas associadas ao vírus, os resultados foram confirmatórios.

ABSTRACT

INTRODUÇÃO: São utilizados vários exames para avaliar os pacientes com queixa de boca seca e, especialmente, os pacientes com Síndrome de Sjõgren, em que estes exames fazem parte de critérios de classificação para estudos científicos. OBJETIVO: Desta maneira, procurou-se avaliar se haveria concordância entre os resultados da sialometria e da cintilografia de glândulas salivares para, se esta concordância estiver presente, optar por apenas um dos dois exames. CASUíSTICA E MÉTODO: Foram avaliados 72 pacientes com boca seca, divididos em grupos não-Síndrome de Sjõgren, com Síndrome de Sjõgren primária e com Síndrome de Sjõgren secundária. Os resultados de sialometria e cintilografia de glândulas salivares foram estudados, procurando-se dimensionar a concordância existente entre eles, através do teste de Kappa. RESULTADOS: Observou-se concordância igual ou próxima de zero entre os dois testes. CONCLUSÃO: Pelos resultados observados, não é possível fazer a opção por um ou outro exame, devendo ambos serem realizados.

The concordance among sialometry and scintigraphy results was evaluated by Kappa test. RESULTS: It was observed that their concordance was equal or near to zero. CONCLUSION: It is not possible to make a choice between these tests and both should be performed.

ABSTRACT

O papilomavírus humano (HPV) é universalmente aceito como agente causal do câncer de colo uterino e, recentemente, vem se especulando sobre sua possível relação com câncer oral e de orofaringe. O carcinoma espinocelular (CEC) oral representa 90 por cento de todos os tumores malignos que afetam a cavidade bucal. Estudos sobre a prevalência de HPV em pacientes com CEC variam de 0 a 100 por cento. O efeito citopático viral mais conhecido é a coilocitose, considerado "critério maior" na infecção pelo HPV do ponto de vista histopatológico. OBJETIVO: O objetivo deste estudo foi verificar a prevalência de achados sugestivos de HPV - coilocitose - em CEC oral e de orofaringe. FORMA DE ESTUDO: coorte transversal. MATERIAL E MÉTODO: Foram examinadas no microscópio 20 lâminas com o diagnóstico de CEC de cavidade oral ou orofaringe sendo que em 15 delas foi encontrada coilocitose, correspondendo a 75 por cento. RESULTADO: Apesar de termos conhecimento que o método com maior sensibilidade atual para pesquisa de HPV ser a reação de polimerase em cadeia (PCR), iniciamos esta pesquisa com a investigação de coilocitose, o que é muito sugestivo de infecção por HPV. CONCLUSÃO: O estudo em questão trata-se de um projeto-piloto pois será dada continuidade a esta pesquisa através da realização de PCR a fim de confirmar a alta prevalência de infecção por HPV em CEC oral e de orofaringe.

ABSTRACT

A relação entre variações anatômicas nasais e dores craniofaciais é analisada com base em uma revisão da literatura a respeito deste assunto. Os fatores fisiopatológicos que podem estar implicados nesta reação se mostram muito mais amplos do que simples alterações do septo nasal e conchas nasais que possam causar estímulo mecânico, através do contato entre estas estruturas abrangendo fatores infecciosos, inflamação neurogênica, correlação com migrâneas e o papel da obstrução nasal. Os achados clínicos de diversos autores incluindo a utilização do teste com anestésico tópico para comprovação desta relação causal, assim como para indicação de tratamento cirúrgico, além dos bons resultados deste tratamento, são citados. Discute-se o mecanismo de alívio da dor obtido através de correções cirúrgicas do septo e conchas nasais Estes dados nos levam a concluir que há múltiplos fatores etiológicos envolvidos, o que, inevitavelmente, questiona o papel do aspecto mecânico como fundamental.

ABSTRACT

A Síndrome de Sjõgren (SS) é considerada uma afecção multissistêmica, crônica, que se caracteriza pela infiltração linfocítica nas glândulas exócrinas e a produção de auto-anticorpos. OBJETIVO: Vários estudos têm notado um aumento na incidência de linfomas malignos em pacientes com SS. Em nosso estudo tentamos descrever esta relação. FORMA DE ESTUDO: Coorte transversal. MATERIAL E MÉTODO: Pacientes com Síndrome Sicca acompanhados no ambulatório de Estomatologia do Departamento de Otorrinolaringologia da Santa Casa de Misericórdia de São Paulo, no período de julho de 1999 a abril de 2002. RESULTADOS: Dos 39 pacientes, 24 foram classificados com SS. A idade variou de 19 a 83 anos, com predominância do sexo feminino (69,7 por cento). O intervalo de tempo entre o início dos sintomas e o diagnóstico de SS variou de 3,77 anos. Não foi observado desenvolvimento de linfoma em nenhum dos pacientes avaliados. CONCLUSÃO: O diagnóstico de SS e o aumento do risco de desenvolvimento de Linfoma ao longo dos anos são importantes, então um longo período de seguimento destes pacientes é fundamental. Observamos que nossos achados foram diferentes quando comparados com a literatura. Nós não encontramos nenhum linfoma em nossos pacientes.

ABSTRACT

A Síndrome de Sjõgren é afecção auto-imune das glândulas exócrinas, que envolve particularmente as glândulas salivares e lacrimais. Não existe exame de certeza para diagnóstico. OBJETIVO: Avaliação da importância do papel da biópsia de glândula salivar menor e da sialometria, isoladamente ou associadas, como métodos utilizados para a classificação da Síndrome de Sjõgren. FORMA DE ESTUDO: Coorte transversal. CASUíSTICA E MÉTODO: Todos os 72 pacientes com queixa de boca seca, de janeiro de 1997 a setembro de 2003, foram submetidos à investigação diagnóstica e classificação com base nos critérios estabelecidos. A sialometria não-estimulada foi realizada com a técnica do swab. Os exames histopatológicos foram avaliados quanto à presença de focos inflamatórios. RESULTADOS: A sialometria não-estimulada e a biópsia de glândula salivar menor apresentaram sensibilidades diferentes para Síndrome de Sjõgren primária e Síndrome de Sjõgren secundária. A sialadenite focal com maior número de focos foi característica da Síndrome de Sjõgren primária. Compararam-se biópsia e sialometria e observou-se que a especificidade e o valor preditivo positivo da biópsia foram maiores. Entre biópsia e biópsia associada à sialometria, a biópsia teve maior sensibilidade e maior valor preditivo negativo. A especificidade da biópsia associada à sialometria foi maior. Entre sialometria e biópsia associada à sialometria, a biópsia associada à sialometria apresentou maior valor preditivo positivo e maior especificidade. A sensibilidade da sialometria foi maior. CONCLUSÕES: Os testes sialometria e biópsia apresentaram desempenhos diferentes nos pacientes com Síndrome de Sjõgren primária e secundária; a positividade dos dois critérios em conjunto aumenta muito a especificidade para Síndrome de Sjõgren (95 por cento).
