Serum vitamin B12 associated with vitamin D/25(OH)D in women with recurrent aphthous stomatitis / Vitamina B12 sérica asociada con vitamina D / 25 (OH) D en mujeres con estomatitis aftosa recurrente

Vitamin B12 and Vitamin D deficiency may contribute to recurrent aphthous stomatitis (RAS). Current studies have showed vitamin B12 to be associated with vitamin D in women, however no study has assessed vitamin B12 associated with vitamin D/25(OH)D in women with RAS. Objective: To investigate the association between serum vitamin B12 and vitamin D/25(OH)D in women with RAS. Materials and Methods: Fourty one women with RAS who meet the inclusion criteria participated in this study. The inclusion criteria were women with RAS without other oral diseases. The exclusions criteria were those who have systemic diseases, taking medications or smoked. All subjects underwent venupuncture to draw blood to quantify serum vitamin B12 and vitamin D/25(OH)D. The characteristic of subjects, severity of RAS, serum Vitamin B12 and Vitamin D/25(OH)D were collected and presented descriptively. The correlation between vitamin B12 and Vitamin D/25(OH)D was analyzed using Pearson correlation test with 95% confidence interval. This study was approved by Medical and Health Ethics Committe, Faculty of Medicine, Universitas Gadjah Mada, Yogyakarta, Indonesia. Results: All RAS subjects have normal mean value of serum Vitamin B12 (453.97+154.44pg/ml) and have low mean value of serum vitamin D/25(OH)D (10.79 +3.29ng/ml) categorized as vitamin D deficiency. The Pearson correlation test showed that there was a significant positive correlation between mean serum Vitamin B12 and Vitamin D/25(OH)D (r= 0.313, p<0.05). Conclusion: There is correlation between vitamin B12 and Vitamin D, and a low level of Vitamin D may contribute in RAS in women.

Antecedentes: la deficiencia de vitamina B12 y vitamina D puede contribuir a la estomatitis aftosa recurrente (EAR). Los estudios actuales han demostrado que la vitamina B12 está asociada con la vitamina D en mujeres, sin embargo, ningún estudio ha evaluado la vitamina B12 asociada con la vitamina D/25 (OH) D en mujeres con EAR. Objetivo: investigar la asociación entre la vitamina B12 y la vitamina D / 25 (OH) D sérica en mujeres con RAS. Material y Métodos: Cuarenta y una mujeres con RAS que cumplen con los criterios de inclusión participaron en este estudio. Los criterios de inclusión fueron mujeres con RAS y sin otras enfermedades orales. Los criterios de exclusión fueron aquellos que tenían enfermedades sistémicas, tomaban medicamentos o fumaban. Todos los sujetos se sometieron a una venupuntura para extraer sangre para cuantificar la vitamina B12 y la vitamina D/25 (OH) D en suero. Las características de los sujetos, la severidad del EAR, la concentración de vitamina B12 y la vitamina D/25 (OH) D sérica fueron recolectadas y presentadas descriptivamente. La correlación entre la vitamina B12 y la vitamina D/25 (OH) D se analizó mediante la prueba de correlación de Pearson con un intervalo de confianza del 95%. Este estudio fue aprobado por el Comité de Ética Médica y de Salud, Facultad de Medicina, Universitas Gadjah Mada, Yogyakarta, Indonesia. Resultado: Todos los sujetos con EAR tienen un valor medio normal de vitamina B12 sérica (453,97pg/ml + 154,44pg/ml) y un valor medio bajo de vitamina D sérica/25 (OH) D (10,79 ng/ml + 3,29ng/ml) clasificado como deficiencia de vitamina D. La prueba de correlación de Pearson mostró que había una correlación positiva significativa entre la vitamina B12 media y la vitamina D/25 (OH) D en suero r=0.313, p<0.05). Conclusión: Existe una correlación entre la vitamina B12 y la vitamina D, y un bajo nivel de vitamina D puede contribuir al RAS en las mujeres.

Recurrent aphthous ulceration: an epidemiological study of etiological factors, treatment and differential diagnosis

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.

Recurrent aphthous stomatitis in 18-year-old adolescents - Prevalence and associated factors: a population-based study

Abstract: Background: Recurrent aphthous stomatitis is a painful disorder of unknown etiology. It is among the most common oral mucosal lesions with high prevalence among young adults. Objectives: To conduct a population-based study with 18-year-old army recruiters to assess its prevalence and associated factors in male adolescents. Methods: Interview during clinical examination in the army. Results: In this group (2,427 interviewed adolescents) there was a RAS prevalence of 24.9%. Smoking, herpes labialis and socioeconomic status correlated with the outcome. Study Limitations: only male adolescents were interviewed. Conclusions: Our results showed high prevalence of RAS; association with higher economic level and herpes simplex was found. Protective effect of smoking was confirmed.

Immune system and zinc are associated with recurrent aphthous stomatitis: an assessment using a network-based approach

OBJECTIVE: The aim of this research was to identify genes, proteins and processes from the biomedical information published on recurrent aphthous stomatitis (RAS) using network-based foci. METHODS: The clinical context was defined using MeSH terms for RAS and biomarkers, combined with words associated with risk. A set of protein coding genes was prioritized using the Génie web server and classified with PANTHER. For defining biologically relevant proteins, protein-protein interaction networks were constructed using Reactome database and Cytoscape. Top 20 proteins were then subjected to functional enrichment using STRING. RESULTS: From 1,075,576 gene-abstract links, 1,491 genes were prioritized. Proteins were related to signaling molecule proteins (n=221), receptor proteins (n=221) and nucleic acid binding proteins (n=169). The network constructed with these proteins included 3,963 nodes and functional analysis showed that main processes involved immune system and zinc ion binding function. CONCLUSIONS: For the first time, bioinformatics tools were used for integrating pathways and networks associated with RAS. Molecules and processes associated with immune system recur robustly in all analyzed information. The molecular zinc ion binding function could be an area for exploring more specific and effective therapeutic interventions

Psychological stress associated with aphthous ulcers and temporomandibular disorders

Objective: To assess the prevalence of stress as an etiological factor for aphthous ulcers and temporomandibular disorders

Study Design: Cross sectional descriptive study

Place and Duration of Study: Armed Forces Institute of Dentistry Rawalpindi, from Oct 2015 to May 2016

Material and Methods: Two groups of patients were selected. Group I included 119 patients presenting with Aphthous Ulcers while group II had 64 subjects with complaints of temporomandibular disorders [TMDs]

After a thorough history, Hospital Anxiety and Depression Scale [HADS] was used to assess stress in the patients. A HADS-A score of 7 was taken as significant anxiety while a HADS-D score of 7 depicted significant depression

Both groups were then subjected to laboratory examinations. Serum cortisol levels were assessed for both groups while Serum Folate, Ferritin and Vitamin B12 level for group I only. Data were analyzed using SPSS version 21 to calculate descriptive statistics including mean and standard deviations as well as frequencies and percentages

Relationship between HADS score and serum cortisol levels was assessed using Pearson's correlation coefficient

A p-value<0.05 was considered significant

Results: For TMDs, 53 [82.8%] patients were found positive for stress while for aphthous ulcers, 61 [51.3%] were positive for stress. The correlation between HADS score and serum cortisol levels was found significant for both groups at a p=<0.001

Conclusions: Patients showed a high prevalence of stress as an etiological factor for aphthous ulcers and temporomandibular disorders in a local setting

Etiologia e tratamento da estomatite aftosa recorrente: revisão de literatura / Etiology and treatment of recurrent aphthous stomatitis: literature review

Objetivos: Descrever as características e os principais achados relatados na literatura quanto à provável etiologia e tratamentos das lesões causadas pela Estomatite Aftosa Recorrente (EAR). Métodos: Realizou-se a revisão da literatura nas bases de dados PubMed, SciELO e LILACS, no período de tempo do ano de 2005 a 2012. Utilizaram-se, isoladamente e em combinação, os descritores a seguir: Stomatitis, Aphthous; Oral Ulcer; Risk Factors e Therapeutics. Resultados: A patogênese da estomatite aftosa recorrente ainda continua indefinida, havendo confirmação científica quanto à sua relação com fatores imunológicos e mutações genéticas. Os procedimentos realizados e recursos utilizados para o tratamento das lesões são paliativos, no intuito de aliviar a dor, não existindo uma terapêutica de cura. Conclusão: Por ser a etiologia da EAR ainda incerta, o tratamento atual das lesões é bastante variado,e baseia-se no alívio dos sintomas da doença, variando, desde o uso de produtos naturais, como a própolis, passando por anti-inflamatórios, até à aplicação do laser de baixa potência.

Objectives: To describe the characteristics and key findings reported in the literature about the possible etiology and treatment of lesions caused by Recurrent Aphthous Stomatitis (RAS). Methods: It was conducted a literature review in the databases PubMed, SciELO and LILACS, from 2005 to 2012. Were used singly or in combination, the following descriptors: Stomatitis, Aphthous; Oral Ulcer; Risk Factors and Therapeutics. Results: The pathogenesis of recurrent aphthous stomatitis still remains unclear, however, there is strong evidence regarding its relationship with immunological factors and genetic mutations. The procedures performed and resources used for the treatment of lesions are palliative in order to relieve pain, there is not a therapeutic healing. Conclusion: As the uncertain etiology of RAS, the current treatment of lesions is very wide, and relies on relieving symptoms of the disease, ranging from the use of natural products, such as propolis, to anti-inflammatories, until the implementation of low-power laser.

Comparing the effect of phenytoin syrup and triamcinolone acetonide ointment on aphthous ulcers in patients with Behcet's syndrome

Recurrent aphthous stomatitis [RAS] appears to be the most common type of oral ulcers. The lesion is usually self limited but its painful presentation results in some difficulties. Therefore, an efficient therapeutic strategy is required and currently existing therapies seem to be inadequate because of its unclear etiology. Here the therapeutic effect of triamcinolone acetonide ointment as a relatively expensive medication has been compared with phenytoin syrup on aphthous ulcers in patients with Behcet's syndrome. Thirty out of 60 our patients with Behcet's syndrome were randomly treated by phenytoin syrup and the remaining were advised to use 0.1% triamcinolone acetonide ointment. After a week, they were visited again to determine the status of aphthous ulcers. Positive response in the triamcinolone acetonide group and phenytoin group was 86.7% and 53.3%, respectively. The effectiveness of triamcinolone acetonide ointment was more than phenytoin on aphthous ulcers in patients with Behcet's syndrome

Epidemiology of recurrent aphthous stomatitis and co-related factors

Recurrent aphthous stomatitis [RAS] is the most common oral ulcerative disease that affects 20% of general population. The etiology of RAS is unknown and it is due several different mechanisms. The purpose of study was to assess the epidemiology and related factors in its occurrence. In this descriptive -cross sectional study, 1105 persons attending to health centers in Zahedan, selected in a multi-stage random manner, were assessed for abundance and effective factors in development of RAS. The data were gathered as single stage and by interview, completion of a questionnaire and clinical examination. The data were analyzed by Chi-squared test using SPSS software. Among 1105 persons [476 males and 629 females] examined, 199 persons [18%] were affected by aphthea and 168 [84.4%] case had minor, 26 case [13.1%] had major and 5 case [2.5%] had herpetiform aphthea. In this research, there were significant correlations between the abundance of RAS and age [P<0.001], education [P<0.001], job [P=0.002], allergy [P=0.02], kind of allergy [P =0.004], predisposing disease [P =0.005], family history [P< 0.001] and brushing [P<0.001]. No significant differences were found between the abundance of RAS and gender, using snuf, tobacco or mouth wash. RAS is a multifactorial lesion and factors such as age, high-stress job, high education, trauma and allergy are positively co-related with occurrence of the aphthea

Ulceração aftosa recorrente no Ambulatório de Estomatologia da UNIFESP / Recurrent aphtous stomatitis in Stomatology Clinic UNIFESP (Universidade Federal de São Paulo)

Introdução e objetivo: A ulceração aftosa recorrente (UAR) é uma doença inflamatória bucal crônica de distribuição mundial, cuja prevalência varia entre 5% e 66%, com média de 30%, e continua representando problema clínico sem solução satisfatória. Apesar da etiopatogenia da UAR ainda ser desconhecida, ela é considerada doença multifatorial, na qual componentes genéticos, microbiológicos e imunológicos concorrem simultaneamente ou sequencialmente para o surgimento e evolução das lesões ulcerativas. Alguns fatores são apontados como modificadores ou desencadeantes das UAR, entre eles os mais estudados estão as alterações hormonais, estresse, traumatismos locais e nutricionais (deficiências de vitamina B12, ácido fólico e ferro). O objetivo deste artigo foi delinear o perfil dos pacientes com UAR acompanhados no Ambulatório de Estomatologia da UNIFESP, no período de 1999 a 2009. Foi elaborado um questionário, assim como um banco de dados para coletar e gerenciar as características clínicas da UAR dos pacientes. Resultados: O tipo mais comum de afta era o tipo minor (92%), o sítio de maior acometimento das lesões era a mucosa jugal (21%), seguida pela mucosa labial, 90% dos pacientes eram não fumantes, em 50% dos pacientes encontramos história familiar de UAR e apenas 28% dos pacientes relacionaram o estresse ao surto de aftas. Apenas 45% dos pacientes relataram piora com alimentação. Conclusões: Concluiu-se que os principais fatores associados à ocorrência da UAR foram predisposição familiar e alimentação e de forma negativa o uso do tabaco.

[Psychiatric evaluation of patients with recurrent aphthous ulceration referred to oral disease department of Mashhad dental school-Iran [2006-2007]]

Recurrent aphthous ulcers [RAS] are one of the most common painful diseases affecting the oral mucosa. The psychological-emotional factors should be considered as predisposing factors. However, the association between psychiatric disorders and RAS has not been fully investigated in Iranian population. The purpose of this study was to determine the type and frequency of psychological disorders in patients with aphthous ulceration. Thirty five subjects of 50 patients suffering from RAS referred to oral medicine department of Mashhad dental school, were enrolled for this study. Demographic data and medical history as well as the number and type of the recurrent ulcers were obtained. The records of SCL9O questionnaire and interviews were analyzed by psychiatrist. Data obtained by personality evaluation and also the frequency of psychopathologic disease according to age, sex and duration of ulcers were described in tables and charts. 65.7% of 35 subjects were female; the average age range was 21-30 years. 74.3% of patients had psychiatric disorders and the others were normal. The most common psychiatric disorder was concurrent minor depression and anxiety. Psychiatric disorders were most common among women. The current study revealed that majority of patients with aphthous ulcers have some kinds of psychiatric disorders especially anxiety, depression and obsession compulsion. The results of this study proposed that all the medical staff should consider psychological disorders as etiologic factors for aphthous ulcers during their work up and treatment

Determinación de Subpoblaciones linfocitarias en lesiones de pacientes con Estomatitis Aftosa Recurrente / Determination of lymphocyte subsets in lesions of patients with recurrent aphthous stomatitis

La Estomatitis Aftosa Recurrente (EAR) es una de las enfermedades más comunes  a nivel de la cavidad bucal. Esta puede presentarse bajo tres formas clínicas diferentes,  menor que es la más prevalente, mayor y herpetiforme. Sin embargo, hasta el presente no ha sido bien establecida su etiología, aunque algunas evidencias indican que los pacientes afectados con esta condición, tienen una respuesta immune celular defectuosa. El objetivo de la presente investigación fue evaluar las subpoblaciones de linfocitos T ayudadores-inductores CD4+ y linfocitos T citotóxicos CD8+ en pacientes con distintos tipos de Estomatitis Aftosa Recurrente. Se evaluaron 19 pacientes, 15 con EAR Menor y 4 tenían EAR Mayor. El grupo control incluyó muestras de encía de diez pacientes sin historia de EAR. A cada uno de los pacientes le fue realizada una biopsia de la lesión y todas fueron procesadas con técnicas de inmunohistoquímica, empleando el método Avidina-Biotina Inmunoperoxidasa. Se observó un marcado aumento en las subpoblaciones de linfocitos en los pacientes con EAR, en comparación con el grupo control. Los  resultados sugieren la implicación de los linfocitos T, y por tanto, de una respuesta inmune mediada por células activadas en la patogénesis de la EAR

Recurrent aphtous stomatitis (RAS) is one of the most common oral mucosal diseases known. It presents as threee types: minor (most prevalent), major and herpetiform. However, not thue well established its etiology although, many evidences indicated that the patients affected with this condition have a defectous celular immune response. The objective of this study was the determination of  the lymphocytes subpopulations T CD4+ and T CD8+ in patients with RAS. We evaluated 19 patients, 15  with minor RAS and 4 with major RAS.  As a control group we included 10 patients withouth RAS.  We obtained a biopsy of each patient, that was procesed by immunohistochemistry. We observed a very high amount of lymphocytes subpopulations in the patients with RAS in comparation with the control group. The results suggested the association  of the T lymphocytes and the the celular immune response in the pathogenesis of the RAS

Estomatitis aftosa recidivante: Conducta odontológica / Recurrent apthous stomatitis: Dentist behaviour

En la cavidad bucal se pueden producir una variedad de enfermedades de diferente etiología, por ello es muy importante que el odontólogo las identifique y conozca las consecuencias que ocasiona si no se previenen o tratan a tiempo. Se funda como premisa que el cuidado periodontal es, en esencia, labor del odontólogo general y que éste no puede pasar por alto la responsabilidad de proveer atención a todos los pacientes. La incidencia excesivamente alta de los problemas periodontales entre las población, dificulta que un número reducido de especialistas los pueda enfrentar. Asimismo, el estrecho vínculo entre los tratamientos dentales restaurativos y los regímenes periodontales hace muy importante que el odontólogo general disponga de conocimientos a fondo sobre periodoncia. Entre las variedades de entidades patológicas con predilección con la cavidad bucal humana de presentación frecuente, están las ulceraciones bucales recidivantes, llamadas comúnmente aftas. Actualmente, la estomatitis aftosa recidivante, se reconoce como la enfermedad más común de la mucosa bucal conocida en el humano. Constituye una de las urgencias en Odontología es una forma de ulceración que se caracteriza por la aparición de una o más ulceras dolorosas con pérdida de la continuidad del epitelio, variable en forma, número y tamaño. Cura en pocos días, semanas o meses dependiendo de los factores de riesgo que la desencadenen. Los ataques pueden repetirse periódicamente. Es importante que el odontólogo, las identifique, así como las consecuencias que ocasiona si no se tratan a tiempo, así como las complicaciones. El propósito de este reporte es describir las diferentes presentaciones clínicas de dicha patología, su etiología, diagnósticos diferenciales y diferentes métodos de tratamiento, además de la interconsulta con diferentes áreas, para valorar sus complicaciones y cuidados postoperatorios

A variety of different etiologies pathologies can affect the oral cavity, due to this reason, dentists must be able to identify them and their consequences if they are not treated on time. It is primordial for the general practitioner dentists the periodontal care of their patients. Among the population the periodontal diseases are very common and only a reduced number of specialists can treat them. The close relation between restorative dental treatments and periodontal treatment procedures lead to the tendency that de general practitioner has enough knowledge in the periodontal field. Among the variety of pathologic entities that affect the oral mucosa, that presents as ulcer and are really recurrent is the aphtous stomatitis in its different types. Actually the recurrent aphtous stomatitis is recognized, as the most common oral mucosa disease at the human beings. It is considered one of the emergencies in dentistry, and appear as one or multiple, different shapes o sizes, painful ulceration, due to the lost of epithelium. They cure in days, weeks or month upon of its type and etiologic factor. Recurrences may be periodically. Dentist must be able to recognize and treat them. The purpose of this research is to describe the possible etiologic agents, clinical features and treatment of this disease and also to recommend the multidisciplinary attention to these patient. For this paper was made a study based on the lineaments of the descriptive documental research, mainly with scientific bibliographic references literature national and international

Estudo de alterações na cavidade oral em pacientes com doença do refluxo gastroesofágico / Study in oral cavity alterations in patients with gastroesophageal reflux disease

RACIONAL: A doença do refluxo gastroesofágico, afecção de elevada e crescente incidência, pode se manifestar através de sintomas típicos (pirose e regurgitação) e atípicos (pulmonares, otorrinolaringológicos e bucais). OBJETIVO:Analisar as alterações na cavidade oral de pacientes com a doença do refluxo gastroesofágico. MÉTODOS: Foram estudados 100 pacientes, sendo 50 acometidos por doença do refluxo gastroesofágico (grupo 1) e 50 controles (grupo 2). Todos os pacientes foram submetidos a exame clínico oral e questionário específico, e naqueles do grupo 1, foram realizadas endoscopia digestiva alta e manometria e pHmetria esofágicas. RESULTADOS: A endoscopia digestiva alta demonstrou esofagite em todos os pacientes, sendo erosiva em 20, não-erosiva em 30 e hérnia hiatal em 38. A pressão média no esfíncter inferior do esôfago foi de 11 ± 4,8 mm Hg e no superior de 75 ± 26,5 mm Hg. Em 42 pacientes do grupo 1 (84 por cento) foi observado refluxo gastroesofágico patológico. O exame clínico oral mostrou: erosões dentárias no grupo 1: 273 faces e no grupo 2: 5; dentes cariados no grupo 1: 23 e 115 no grupo 2; abrasão no grupo 1: 58 e no grupo 2: 95; desgaste por atrito: 408 no grupo 1 e 224 no grupo 2. A face dental mais acometida foi a palatina. No grupo 1, 21 pacientes referiam queixas de aftas freqüentes, 35 sensibilidade dentária, 26 ardência bucal e 42 gosto azedo na boca. Naqueles do grupo 2 estas queixas foram observadas em menor número de pacientes. CONCLUSÕES: Os doentes com doença do refluxo gastroesofágico apresentam maior incidência de erosões dentárias, aftas, ardência bucal, sensibilidade dentária e gosto azedo que os controles e menor incidência de lesões cariosas em relação aos controles.

BACKGROUND: The gastroesophageal reflux disease, which has become highly and increasingly incident, may be manifested by typical (pyrosis and regurgitation) and atypical (pulmonary, otorhinolaryngological and buccal) symptoms. AIM: To analyze alterations in the oral cavity patients with gastroesophageal reflux disease. METHODS: One hundred patients were studied being 50 gastroesophageal reflux disease patients (group 1) and 50 controls (group 2). All patients were submitted to an oral clinical exam and specific survey. Patients in group 1 were submitted to upper endoscopy, manometry and esophageal pH monitoring. RESULTS: The upper endoscopy revealed esophagitis in all patients, 20 erosive esophagitis, 30 no-erosive esophagitis and 38 hiatal hernia. Average pressure of the lower esophageal sphincter was 11 ± 4,8 mm Hg and of the upper esophageal sphincter 75 ± 26,5 mm Hg. In 42 patients of group 1 (84 percent) pathological gastroesophageal reflux was observed. Clinical exams revealed: dental erosions in group 1: 273 faces and in group 2: 5 tooth decays in group 1: 23 and 115 in group 2; abrasion in group 1: 58 and in group 2: 95; attrition wear: 408 in group 1 and 224 in group 2. The most damages was the palatine face. In group 1, 21 patients complained about frequent episodes of cankers sores, 35 of tooth sensibility, 26 of burning mouth and 42 of sour taste in the mouth. In group 2 the complaints were observed in lower number of patients. CONCLUSIONS: Patients with gastroesophageal reflux disease present higher incidence of dental erosion, cankers sores, mouth burning sensation, sensitivity and sour taste than controls. Patients with gastroesophageal reflux disease show lower incidence of tooth decays as compared to controls.

Factores inmunológicos y microbiológicos asociados con la etiología de la estomatitis aftosa recurrente / Microbiological and immunological factors associated with the etiology of recurrent aphthous stomatitis

La Estomatitis Aftosa Recurrente (EAR) es una enfermedad ulcerativa, dolorosa y muy común de la cavidad bucal, cuya etiología es desconocida. Algunos reportes han señalado que los pacientes afectados con esta condición presentan una respuesta inmunológica defectuosa. Adicionalmente, existe atención en destacar la importancia y participación de las moléculas de adhesión en el reclutamiento del infiltrado inflamatorio en esta condición. Las moléculas de adhesión VCAM-1 (molécula de adhesión vascular-1) e ICAM-1 (molécula de adhesión intercelular-1), son esenciales para la unión de las células inflamatorias a las células endoteliales. Formas circulantes de estas moléculas han sido detectadas en un número de enfermedades vasculíticas, y EAR tiene características similares a esta entidad. Por otra parte Helicobacter pylori ha sido demostrado como el agente causal de la úlcera gástrica que presenta gran similitud histológica con la EAR. El objetivo del presente trabajo es realizar una revisión de los principales factores inmunológicos y microbiológicos, asociados con la EAR

Recurrent aphtous stomatitis (RAS) is a common, painful and ulcerative disorder of the oral cavity of unknown etiology. Several reports have suggested that the patients affected with this condition have a defectous celular immune response. Aditionally, adhesion molecules are known to play a crucial role in the recruitment of immflamatory cells to sites of inflammation. Adhesion molecules VCAM-1 (vascular cell adhesion molecule-1), and ICAM-1 (intercellular adhesion molecule-1) are essential for the binding of inflammatory cells to Endothelial cells. Circulating forms of these molecules have been detected in a number of vasculitic disease. RAS has some features of a vasculitic disease process. Helicobacter pylori has been shown to be the causative factor in peptic ulcers, which is very similar with RAS The aim of this study was to review the inmmunological and microbiological factors associated with the etiology of RAS

Condições bucais relacionadas com o estresse: uma revisão dos achados atuais / Buccal conditions related with the stress: a revision of the current discoveries

O desequilíbrio da harmonia entre o corpo e a mente é o que origina o desenvolvimento de doenças relacionadas ao estresse. Muitas patologias hoje estudadas têm íntima relação com o estresse, e estabelecer a relação estresse/doença é fundamental para conhecer e tratar algumas dessas patologias. Considerando-se a importância do tema para os alunos e profissionais da Odontologia, justifica-se a realização deste trabalho, com vista ao melhor entendimento acerca do tema abordado e ao aprimoramento do diagnóstico das mesmas. Podemos sugerir que os aspectos psicossociais, em especial o estresse, têm sua participação na etiologia de algumas condições na cavidade bucal, atuando de forma conjunta com outros fatores, entretanto o papel do estresse nessas condições estudadas não está perfeitamente esclarecido. É necessário enfatizar que estas condições devem merecer atenção especial do cirurgião dentista, que, por sua vez, faz parte de uma equipe multidisciplinar no atendimento do paciente, sendo necessário o encaminhamento do paciente portador de uma dessas condições associadas ao estresse a profissionais especializados, para uma terapia adjunta, podendo melhorar sobremaneira o resultado do tratamento odontológico.

The unbalance between body and mind is what originates the development of diseases related to stress. A number of pathologies today studied has intimate relationship with stress. To establish the relationship between stress and disease is fundamental to know and to treat some of those pathologies. Considering the importance of the issue for dental students and professionals, it is justified the accomplishment of this work, with view to the best understanding about the approached theme and to the establishment of the its diagnosis. We can suggest that the psico-social aspects, especially stress, have their participation in the aetiology of some conditions in the oral cavity, acting in varied ways with other factors. However, the role of stress in those studied conditions is not perfectly understood. It is necessary to emphasize that these conditions should have the dentist’s special attention and are part of a multidisciplinary team in the patient’s attendance, being necessary the direction of the patient bearer of one of those conditions associated to stress to specialized professionals for an attached therapy.

Se describe el caso de un varón de 7 años que se presenta clínicamente con episodios recidivantes de fiebre, aftas y manifestaciones de meningoencefalitis, con hiperproteinorraquia y pleocitosis linfocitaria. Se descartaron otros diagnósticos diferenciales. Con imágenes patológicas en RNM de iso o hipointensidad en T1, hiperintensidad en T2 y Flair, en mesencéfalo, pedúnculos cerebelosos, protuberancia, cuerpo calloso, ganglios basales y cápsula interna y hemisferios cerebrales. En la evolución agrega signos cutáneos cumpliendo con los criterios diagnósticos establecido Grupo Internacional de Estudio de Enfermedad de Behçet. Se realizó tratamiento corticoideo e munosupresor.Destacamos que los criterios diagnósticos internacionales tienen un valor relativo en la etapa prepuberal, dado que las manifestaciones oculares y genitales son infrecuentes y el compromiso parenquimatoso neurológico puede ser su forma de expresión clínica principal.

The case of a 7-year-old Uruguayan boy with recurrent episodes of fever, oral aphthas lesions and meningoencephalitis with elevated protein levels and lymphocytic pleocytosis is presented. Other diagnoses were excluded. MRI showed in acute stages CNS involvement in iso- or hipointense in T1- weighted images and hyperintense in T2-weighted or fluid- attenuated inversion recovery (FLAIR) images in mesodiencephalic junction, cerebellar peduncles, pons, corpus callosum, basal ganglia and internal capsule, and cerebral hemispheres. In the evolution skin lesions appeared, fulfilling the International Study Group Criteria for the Diagnosis of Behçet' Disease. Corticosteroids and immunosuppressant treatment was done.The main difficulty in children is having all the criteria for diagnosis; especially when recurrent genital ulceration and eye lesion rarely appear at this age.

Comparison of oral microbial flora and pH of patients with recurrent aphthous stomatitis during relapse and remission

Recurrent aphthous stomatitis is a relapsing disease with typical ulcers that involve the oral mucosa. The objective of this study was to determine the microbial flora and pH of mouth in patients during and between disease relapse. Patients were selected by simple non-r and om sampling. Totally 28 patients were included in this study. After filling out a questionnarie, patients were referred to the laboratory and a sample from oral ulcer was obtained and cultured in both aerobic and anaerobic media. PH of mouth was measured by pH meter. Same process was repeated two weeks after remission. Considering non-group A Streptococci and gram positive bacteria, there were no changes in oral flora culture in aerobic environment in relapse and remission time. Staphylococcus aureus growth was seen in aerobic environment in 3 [10.7%] patients in relapse and in 2 [7.1%] in remission which was not statistically significant. There were not considerable changes in group A Streptococci in remission and relapses and also in gram negative bacilli. But in anaerobic cultures there was considerable increase of non-group A Streptococcus in relapse and remission [71/4%, in relapse and 39.3% in remission, P<0.01]. There were not specific changes in other bacteria. There was higher oral pH in 53.3% of patients, lower pH in 20% and no change in pH in 26.7% of patients during active phase of disease. There is considerable increase in non-A Streptococcus and increasing oral pH in majority of patients with aphthous stomatitis in relapse time
