Melkersson-Rosenthal syndrome: a classical case report / Síndrome de Melkersson-Rosenthal: relato de caso clássico

ABSTRACT The Melkersson-Rosenthal syndrome constitutes a rare manifestation characterized by a triad of signs and symptoms: recurrent orofacial edema, fissured tongue, and recurrent facial paralysis. The difficulty in diagnosing Melkersson-Rosenthal syndrome is that orofacial edema is common to various diseases besides the lack of awareness of the syndrome by health professionals and the frequent metachronous manifestation of its symptomatology. The aim of this report is to present a classical case of Melkersson-Rosenthal syndrome and its clinical and therapeutic approach. A patient who sought for assistance at the Stomatology Clinic presented a synchronous manifestation of the triad: a left lip and cheek nonpitting edema accompanied by facial paralysis on the same side and fissured tongue. Melkersson-Rosenthal syndrome was diagnosed due to the presence of the triad of signs and symptoms after initially ruling out Crohn's disease, Sarcoidosis, and tuberculosis due to a lack of intestinal or respiratory complaints and absence of other clinical evidence. The treatment administered was steroids, the most common treatment with a satisfied prognosis we found in the literature for Melkersson-Rosenthal syndrome patients. We recommend its implementation intralesional injections of betamethasone dipropionate as after four infiltrations the edema subsided by 80% with no further relapses within one-year follow-up.

RESUMO A síndrome de Melkersson-Rosenthal constitui uma manifestação rara caracterizada por uma tríade de sinais e sintomas: edema orofacial recorrente, língua fissurada e paralisia facial recorrente. A dificuldade no diagnóstico da síndrome de Melkersson-Rosenthal é que o edema orofacial é comum a diversas doenças, além do desconhecimento da síndrome pelos profissionais de saúde e da frequente manifestação metacrônica de sua sintomatologia. O objetivo deste relato é apresentar um caso clássico de síndrome de Melkersson-Rosenthal e sua abordagem clínica e terapêutica. Paciente procurou atendimento no Ambulatório de Estomatologia apresentando manifestação sincrônica da tríade: edema não depressível em lábio e bochecha esquerdos acompanhado de paralisia facial do mesmo lado e língua fissurada. A síndrome de Melkersson-Rosenthal foi diagnosticada devido à presença da tríade de sinais e sintomas após a exclusão inicial de doença de Crohn, sarcoidose e tuberculose por ausência de queixas intestinais ou respiratórias e ausência de outras evidências clínicas. O tratamento administrado foi o esteroide, sendo o tratamento mais comum com prognóstico satisfatório que encontramos na literatura para pacientes com SRM. Recomendamos a aplicação de injeções intralesionais de dipropionato de betametasona, pois após quatro infiltrações o edema cedeu em 80% sem novas recidivas em um ano de seguimento.

Voltage-gated sodium channels gene expression in Burning Mouth Syndrome: a case-control study

Abstract Burning mouth syndrome (BMS) is a condition characterized by painful symptoms of the oral mucosa, despite the absence of any clinical signs. Its etiology is unknown, and there is still no effective treatment to date. Current evidence has shown neuropathic impairment in BMS patients. Neuropathic pain can be related to the dysfunction of voltage-gated sodium channels, considering that these receptors regulate the induction of action potentials in nociceptive neurons. This study evaluated the gene expression of voltage-gated sodium channels Na v 1.7, Na v 1.8 and Na v 1.9 in these patients. The gene expressions of these channels were assessed by real time RT-PCR analysis of fresh-frozen tongue biopsies in a case-control study composed of 12 patients with BMS, and 5 healthy control patients, proportionally matched by sex and age, and analyzed using the 2^(-Delta Delta CT) method. There was no statistically significant difference between the analyzed groups, despite the increase in Na v 1.7 (fold-change = 3.13, p = 0.52) and decrease in Na v 1.9 (fold-change = 0.45, p = 0.36) gene expression in the BMS group. The Na v 1.8 gene was not expressed in any of the samples analyzed. Although the gene expression in the voltage-gated sodium channels in BMS under study seems to be comparable with that of the normal oral mucosa, the functionality of these channels in BMS has not yet been identified, thus suggesting that further research is needed to better understand these voltage-gated sodium channels.

Antifungal efficiency of chemically and thermally-activated acrylic resins after surface treatment using poly (diallyldimethylammonium chloride)

Abstract INTRODUCTION: Acrylic resins are used in the preparation of facial prostheses and may be colonized by fungi. Here, we verified the antifungal efficacy of this material after surface treatment using poly (diallyldimethylammonium chloride). METHODS: Acrylic resin specimens with and without surface treatment were subjected to tests for fungistatic and fungicidal activities. Standard strains of Candida albicans and Aspergillus niger were used. RESULTS: After surface treatment, the fungistatic and fungicidal efficacies of the resins against C. albicans and fungistatic action against A. niger were verified. CONCLUSIONS: The surface treatment was a determinant of the antifungal activity of the material.

Clinical characteristics and therapeutic response in patients with Burning Mouth Syndrome: accompanying 2 years / Características clínicas e resposta terapêutica em pacientes portadores da Síndrome de Ardência Bucal: acompanhamento de 2 anos

Introduction: Burning Mouth Syndrome (BMS) is a condition characterized by burning symptom of the oral mucosa in the absence of clinical signs. Its etiology is still unknown and, and to date there is no effective treatment. Purpose: The aim of this study was to evaluate patients with BMS profile and the therapies results in a retrospective study. Material and method: Clinical and therapeutic data were collected from records of patients with BMS diagnosed between January 2013 to April 2015 at the Clinic of Stomatology Clinic, Faculdade de Odontologia of Universidade de São Paulo, according to the criteria established by the International Headache Society in 2013. The therapies used for BMS control were also evaluated. Result: Twelve patients were diagnosed with BMS at this period. All of them were women with a mean age of 61.18 years and the apex of the tongue was the most common affected site and the duration of the burning sensation ranged from 6 months to 25 years. Many therapies were prescribed for BMS control, such as topical capsaicin, topical clonazepan, low level laser therapy and homeopathy. Among the established therapies, capsaicin has immediate effect in reducing symptoms. Conclusion: The present study showed that the challenges towards an effective treatment for BMS are varied and are mainly related to the lack knowing of the pathogenesis of this disease. The demographic profile of patients studied here was similar to that described in the available literature, however, the variables represented by secondary symptoms (medical history, anxiety and depression levels) may be modifying factors of therapeutic response and the pathogenesis of the disease itself.

Introdução: A Síndrome de Ardência Bucal (SAB) é uma condição caracterizada pelo sintoma de ardência na mucosa oral na ausência de qualquer sinal clínico. Sua etiologia ainda é desconhecida e, até o momento, não dispõe de tratamento efetivo. Objetivo: Avaliar o perfil do paciente portador de SAB, as terapias instituídas e seus resultados em estudo retrospectivo. Material e método: Foram coletados os dados clínicos e terapêuticos dos prontuários de pacientes diagnosticados com SAB, no período de janeiro de 2013 a abril de 2015, no Ambulatório da Disciplina de Estomatologia Clínica da Faculdade de Odontologia da Universidade de São Paulo. Os critérios para o diagnóstico utilizados se basearam nos estabelecidos pela International Headache Society em 2013 e foram observadas as terapêuticas empregadas e seus resultados. Resultado: Doze pacientes foram diagnosticadas com SAB neste período, todas do sexo feminino, média de idade 61,18 anos, e a principal região acometida pelo sintoma de ardor foi o ápice de língua. O tempo de duração deste sintoma variou de 6 meses a 25 anos. As terapias utilizadas para o controle de sintomas da SAB foram capsaicina, clonazepan tópico, laserterapia e homeopatia. Dentre as terapias instituídas, a capsaicina apresentou efeito imediato na redução dos sintomas. Conclusão: O presente estudo demonstrou que os desafios que circundam a obtenção de um tratamento efetivo para a SAB são diversos e estão principalmente relacionados ao desconhecimento da etiopatogenia da doença. O perfil demográfico dos pacientes aqui estudados foi semelhante ao descrito na literatura disponível, entretanto, as variáveis representadas por sintomas secundários (história médica, níveis de ansiedade e depressão) podem constituir fatores modificadores da resposta terapêutica e da própria etiopatogenia da doença.

Rosai-Dorfman disease affecting the maxilla

Rosai-Dorfman disease (RDD), formerly called sinus histiocytosis with massive lymphadenopathy, is a non-neoplastic proliferative histiocytic disorder with behavior ranging from highly aggressive to spontaneous remission. Although the lymph nodes are more commonly involved, any organ can be affected. This study aimed to describe the features and the follow-up of a case of extranodal RDD. Our patient was a 39-year-old woman who was referred with an 11-month history of pain in the right maxilla. On clinical examination, some upper right teeth presented full mobility with normal appearance of the surrounding gingiva. Radiographic exams showed an extensive bone reabsorption and maxillary sinus filled with homogeneous tissue, which sometimes showed polypoid formation. An incisional biopsy demonstrated a diffuse inflammatory infiltrate rich in foamy histiocytes displaying lymphocytes emperipolesis. Immunohistochemistry showed positivity for CD68 and S-100, and negativity for CD3, CD20, and CD30. Such features were consistent with the RDD diagnosis. The patient was referred to a hematologist and corticotherapy was administrated for 6 months. RDD is an uncommon disease that rarely affects the maxilla. In the present case, the treatment was conservative, and the patient is currently asymptomatic after 5 years of follow-up.

Low Intensity laser therapy in patients with burning mouth syndrome: a randomized, placebo-controlled study

Abstract The aim of this study was to assess the effectiveness of low intensity laser therapy in patients with Burning Mouth Syndrome (BMS). Thirty BMS subjects were randomized into two groups - Laser (LG) and Placebo (CG). Seven patients dropped out, leaving 13 patients in LG and 10 patients in CG. Each patient received 4 irradiations (laser or placebo) twice a week, for two consecutive weeks (blinded to the type of irradiation received). Infrared laser (AsGaAI) irradiations were applied to the affected mucosa in scanning mode, wavelength of 790 nm, output power of 20 mW and fluence of 6 J/cm2. A visual analogue scale (VAS) was used to assess the therapeutic effect before and after each irradiation, and at all the control time periods: 7, 14, 30, 60 and 90 days after the last irradiation. One researcher delivered irradiation and another recorded the results. Both researchers were blinded, the first to the results, and the second to the type of radiation applied. The results were categorized according to the percentage of symptom level variation, and showed a statistically better response in LG in only two categories of the control checkpoints (p=0.02; Fisher's Exact Test). According to the protocol used in this study, low intensity laser therapy is as beneficial to patients with BMS as placebo treatment, indicating a great emotional component of involvement in BMS symptomatology. Nevertheless, there were positive results in some statistical analyses, thus encouraging further research in BMS laser therapy with other irradiation parameters.

Evaluation of fine needle aspiration biopsy in oral cavity and head and neck region with different stains techniques

The present study aimed to evaluate the Fine Needle Aspiration Biopsy in different staining techniques in nodular lesions of the oral cavity and head and neck region, as their sensitivity, specificity and accuracy, staining with Panoptic, Papanicolaou and Hematoxylin-Eosin (H&E) stains. 46 patients who sought the Clinic of the Discipline of Clinical Stomatology at FOUSP were selected consecutively, with nodular lesions in the oral cavity and head and neck region. The material obtained by FNAB was sent on 6 different slides, stained by the method of Panoptic, Papanicolaou and H&E, to the same pathologist only with the clinical diagnosis. After the final report of FNAB, the biopsy report was issued, serving as gold standard. After the calculations, the results of sensitivity, specificity and accuracy for Panoptic staining were 28.6%, 76% and 15.4%, respectively. The result of sensitivity, specificity and accuracy for Papanicolaou staining were 71.4%, 76.7% and 23.3%, respectively. The result of sensitivity, specificity and accuracy for H&E staining were 82.1%, 23.3%, 28.6%, respectively. We can conclude, according to the methodology of this study that, H&E and Papanicolaou stains showed the same sensitivity of diagnosing malignant neoplasms. H&E stain showed a better specificity for diagnosing benign neoplasms, compared with Papanicolaou and Panoptic stains. H&E stain showed better accuracy, to give definitive diagnosis, followed by Papanicolaou and Panoptic stains.

Análise do perfil de expressão gênica das quimiocinas e seus receptores em portadores de estomatite aftosa recorrente / Analysis of gene expression profile of chemokines and their receptors in patients with recurrent aphthous stomatitis

Os aspectos moleculares envolvidos na expressão das estomatites aftosas recorrentes (EAR) vem, de forma crescente, auxiliando a compreensão e o desvendamento das bases etiopatogênicas da doença. Dessa forma, o objetivo deste trabalho foi o de traçar um perfil da expressão de quimiocinas e seus receptores em pacientes portadores de estomatite aftosa recorrente, desde que essas citocinas são responsáveis pelo tráfego de leucócitos e gerenciamento de várias vias de sinalização nas reações inflamatórias, visando contribuir com o entendimento das bases moleculares desta doença. Foram constituídos dois grupos de pacientes; um grupo caso composto por pacientes portadores de EAR, e um grupo controle composto por voluntários saudáveis sem história de EAR. Foram colhidas biópsias de lesões recentes de EAR no grupo caso e fragmentos de mucosa oral normal dos voluntários sadios. Extraiu-se o RNA dessas amostras, constituindo-se dois conjuntos (pools) de material genético: um do grupo caso e outro do grupo controle. Esse material foi utilizado em técnica de PCR-array, em placas contendo 84 genes codificadores de quimiocinas e seus receptores, além de outros genes relacionados. Os resultados mostraram superexpressão de 31 genes e hipoexpressão de outros sete, sendo que entre as quimiocinas avaliadas, 16 mostraram superexpressão e uma hipoexpressão. Entre os receptores, oito se superexpressaram e um mostrou-se hipoexpresso. Todas as quirniocinas superexpressas foram do tipo inflamatório, à exceção de duas (CCL 19, CXCL 13), sendo que as quimiocinas CXCL6, CXCL9, CXCL 10 e CXCL 11 mostraram expressão extremamente elevada. Concluímos que as quimiocinas desempenham papel importante na manifestação das EAR e que o perfil das quimiocinas superexpressas é do tipo inflamatório e associado à reação inflamatória do tipo Th1...

The molecular aspects associated to recurrent aphthous stomatitis (RAS) expression are increasingly aiding our understanding of the etiopathogenesis of this condition. Thus, the objective of this study was to draw a profile on the expression of chemokines and their receptors in patients with recurrent aphthous stomatitis, since these cytokines are responsible for the traffic of leukocytes and managing multiple signaling pathways in inflammatory reactions, aiming to contribute to the understanding of the molecular basis of this disease.Two groups of patients were constituted, a Case group consisting of patients with RAS, and a Control group composed of healthy volunteers with no history of RAS. Biopsies were taken from recent RAS lesions in the case group and fragments of normal oral mucosa of healthy volunteers. RNA was extracted from these samples constituting two sets (pools) of genetic material; one from case group and one from control group. This material was applied in PCR-array plates containing 84 genes encoding chemokines and their receptors, and other related genes. The results showed overexpression of 31 genes and hypoexpression of other seven. Among the chemokines genes evaluated, 16 showed overexpression and one hypoexpression. Among receptors eight were overexpressed and one showed hypoexpression .. Ali but two (CCL 19, CXCL 13) of the overexpressed chemokines were of inflammatory type. The inflammatory chemokines CXCL6, CXCL9, CXCL 10, and CXCL 11 showed extremely high expression .. It was concluded that chemokines play an important role in the manifestation of RAS and that the profile of verexpressed chemokines is of inflammatory type and associated to a Th1 inflammatory reaction...

Fine needle aspiration biopsy in the oral cavity and head and neck region

The objective of the current study was to evaluate the sensitivity, specificity and accuracy of fine needle aspiration biopsy (FNAB) of submucous nodules from the oral cavity and head and neck region as an auxiliary diagnostic tool. Fifty patients with nodule lesions in the oral cavity and the head and neck region were selected. All of them were submitted to FNAB and to either incisional or excisional biopsy. The diagnoses from the FNABs were compared with the biopsy diagnosis as the gold standard. All the cases of FNAB were analyzed by a single oral pathologist prior to the biopsy diagnosis. The results showed that the sensitivity of FNAB was 75 percent, its specificity was 96 percent and its accuracy was 58.8 percent. The false positive and false negative rates were 6.7 percent and 13.3 percent, respectively. The positive predictive value was 86 percent and the negative predictive value was 93 percent. The inconclusive rate was 16/50. FNAB displayed a high success rate for identifying both malignant and benign lesions, but a low accuracy for making a final diagnosis.

Psychological stress and recurrent aphthous stomatitis

INTRODUCTION AND OBJECTIVES: Recurrent aphthous stomatitis (RAS) is the most common type of ulcerative disease of the oral mucosa. Despite its worldwide occurrence and the extensive amount of research that has been devoted to the subject, the etiology of RAS remains unclear. Nevertheless, several hereditary, nutritional, infectious and psychological factors have been associated with RAS. The aim of this case-control study was to assess the influence of psychological stress on the manifestation of RAS. METHOD: Fifty patients were enrolled in the trial. Twenty-five RAS patients constituted the study group and another 25 non-RAS patients who were similarly matched for sex, age and socioeconomic status constituted the control group. Each patient was evaluated in terms of the four domains of stress (emotional, physical, social and cognitive) using an internationally validated questionnaire, which was comprised of 59 items and measured the frequency and intensity of stress symptoms. The RAS group was interviewed during an active RAS episode. Completed questionnaires were submitted to proper analytical software and interpreted by an expert psychologist. RESULTS: There was a higher level of psychological stress among RAS group patients when compared to the control group (P < 0.05). CONCLUSION: Psychological stress may play a role in the manifestation of RAS; it may serve as a trigger or a modifying factor rather than being a cause of the disease.

Systemic treatment in severe cases of recurrent aphthous stomatitis: an open trial

PURPOSE: This study aimed to evaluate the efficacy of the systemic drugs thalidomide, dapsone, colchicine, and pentoxifylline in the treatment of severe manifestations of RAS. METHODS: An open, 4-year clinical trial was carried out for 21 consecutive patients with severe RAS. Initially, patients were given a 2-week course of prednisone to bring them to a baseline status. Simultaneously, one of the four test drugs was assigned to each patient to be taken for a period of 6 months. During the course of the trial, patients were switched to one of the other three drugs whenever side effects or a lack of satisfactory results occurred, and the 6-month limit of the treatment was then reset. RESULTS: The most efficient and best-tolerated drug was thalidomide, which was administered to a total of eight patients and resulted in complete remission in seven (87.5 percent). Dapsone was prescribed for a total of nine patients, of whom eight (89 percent) showed improvement in their symptoms, while five showed complete remission. Colchicine was administered to a total of ten patients, with benefits observed in nine (90 percent), of whom four showed complete remission. Pentoxyfilline was administered to a total of five patients, with benefits observed in three (60 percent), of whom one patient showed complete remission. CONCLUSION: The therapeutic methods used in this trial provided significant symptom relief. Patients experienced relapses of the lesions; however, this occurred after withdrawal of their medication during the follow-up period.

Laser de baixa potência na prevenção de mucosite em pacientes submetidos à quimioterapia com fluorouracil e ácido folínico / Low level laser therapy in oral mucositis prevention on patients submitted to fluorouracil and folinic acid chemotherapy

O objetivo deste estudo foi verificar a eficácia do laser de baixa potência na prevenção da mucosite oral em pacientes portadores de adenocarcinoma de cólon, submetidos à quimioterapia com fluorouracil (5-FU) e ácido folínico (Leucovorin). Quarenta e oito pacientes foram incluídos no estudo: 18 homens e 30 mulheres, na faixa etária dos 37 aos 78 anos (média 62,5 anos). Vinte e cinco pacientes compuseram o grupo submetido à aplicação preventiva de laser (Grupo LP) e 23 pacientes receberam aplicação placebo (Grupo C). A aplicação do laser, preventivo ou placebo, foi realizada na semana de infusão da quimioterapia, uma única vez, e os pacientes foram reavaliados após sete dias. O laser utilizado foi o AlGaInP nm, 660 nm, fluência de 3 J/cm². Os graus de mucosite foram mensurados pela escala WHO. Intensidade de dor e xerostomia foram avaliados por meio de escala visual analógica (EVS). Vinte e um pacientes cumpriram os seis ciclos programados de quimioterapia (10 C e 11 LP), e 27 pacientes completaram apenas parte do protocolo (13 C e 14 LP). A freqüência de mucosite variou em torno de 50% em cada ciclo. Foram registrados 95 episódios de mucosite em 188 ciclos de quimioterapia. A análise estatística não mostrou diferença significativa entre os grupos. Pacientes com queixa de alteração de paladar prévio à quimioterapia e história de diabetes mellitus e gastrite manifestaram quadros mais graves de mucosite que a média da população estudada. A aplicação de laser de baixa potência com finalidade terapêutica mostrou-se bastante efetiva no controle da sintomatologia associada à manifestação de mucosite oral. Concluímos que uma única aplicação de laser de baixa potência não foi efetiva para previnir a mucosite oral na população estudada.

Quality of life in patients submitted to surgical treatment for minor salivary gland neoplasms

This study was aimed at assessing the quality of life in patients submitted to surgical treatment for minor salivary gland neoplasms (MSGN). Twelve patients (10 women and 2 men, mean age: 49.4 years) with histopathologic diagnosis of pleomorphic adenoma (PA, 3 cases), polymorphous low-grade adenocarcinoma (PLGA, 2 cases), cystic adenoid carcinoma (CAC, 4 cases), and muco-epidermoid carcinoma (MEC, 3 cases) were evaluated. All of them were treated by surgical excision; patients with CAC received radiotherapy as well. The patients’ quality of life was evaluated through a self-administered questionnaire concerning their physical well-being, emotional status, normal daily activities, and family relationships. The results showed that patients with MEC - the youngest among all patients - reported a significantly greater worsening of their physical well-being and emotional status after treatment as compared with patients treated for PA (P < 0.05), and also of their functional activities as compared with those treated for PA and PLGA (P < 0.05). In conclusion, age of development of the neoplasm and type of disease produce more impact on patients’ quality of life than does the therapy’s degree of aggression.

Este estudo teve por objetivo avaliar a qualidade de vida em pacientes submetidos a tratamento cirúrgico para neoplasias de glândulas salivares menores (NGSM). Doze pacientes (10 mulheres e 2 homens, idade média de 49,4 anos) com diagnóstico histopatológico de adenoma pleomórfico (AP, 3 casos), adenocarcinoma polimorfo de baixo grau de malignidade (APBG, 2 casos), carcinoma adenóide cístico (CAC, 4 casos), e carcinoma muco-epidermóide (CME, 3 casos) foram avaliados. Todos os pacientes foram tratados por excisão cirúrgica; pacientes com CAC receberam radioterapia complementar. A qualidade de vida dos pacientes foi avaliada através de um questionário de auto-avaliação referente ao bem-estar físico, estado emocional, atividades normais diárias, e relações familiares. Os resultados mostraram que os pacientes com CME - os mais jovens entre todos os pacientes - relataram uma piora significativamente maior em seu bem-estar físico e estado emocional após o tratamento quando comparados com pacientes tratados de AP (P < 0,05), e também em suas atividades funcionais quando comparada com indivíduos tratados de AP e APBG (P < 0,05). Em conclusão, a idade de desenvolvimento da neoplasia e o tipo de doença produzem maior impacto na qualidade de vida do paciente do que faz o grau de agressão do tratamento.

Aspectos clínicos, patológicos e imaginológicos de um caso de displasia fibrosa / Clinic, pathological and imageologic aspects of a fibrous dysplasia case

: A displasia fibrosa é uma afecção não neoplásica caracterizada por um período de substituição gradativa do tecido ósseo normal por tecido fibro-ósseo, que eventualmente sofre um processo de calcificação. O objetivo deste trabalho é apresentar um caso atípico de displasia fibrosa monostótica dos maxilares, cujas características distintas foram mais evidenciadas pela análise da tomografia computadorizada. Radiografia convencional e cintilografia óssea foram também realizadas para permitir um diagnóstico apropriado e descartar uma doença poliostótica. A tomografia computadorizada mostrou ser o melhor método para avaliação de lesões de displasia fibrosa maxilofacial e deveria ser o exame de escolha para acompanhar pacientes com esta doença

Enterobacteria and oral ulceration in HIV+ and RAU populations

Investigamos a ocorrência de enterobactérias em ulceraçöes bucais de pacientes HIV+ e portadores de ulceraçöes aftosas recorrentes (UAR), coletando amostras através de "swabs" e semeando o material em placas contendo ágar MacConkey. Utilizamos populaçäo controle de indivíduos sadios, para comparaçäo de resultados. Obtivemos 41,6 por cento de positividade para enterobactérias nas amostras do grupo HIV (10/24), 10 por cento no grupo UAR (2/20) e 20 por cento no grupo controle (4/20). Os resultados sugerem correlaçäo entre ulceraçöes bucais em pacientes imunossuprimidos pelo HIV e maior ocorrência de enterobactérias, sem relaçäo entre UAR e enterobactérias
