Láser de baja frecuencia para aftas mayores recurrentes. Caso Clínico / Low frequency laser for major recurrent aphthous stomatitis. Clinical case

La estomatitis aftosa recurrente (menor, mayor o herpética) es una de las enfermedades bucodentales más frecuentes, de etiología multifactorial y con predisposición genética. Para esta patología su diagnóstico es clínico, y tomando como base la historia clínica se puede discriminar con otras patologías ulcerativas. La terapia con láser de baja potencia (LLLT) se propone como un tratamiento no invasivo, actuando como un fotomodulador celular, por lo que reduce el dolor, la inflamación, y estimula la regeneración tisular, previniendo daños. En el presente artículo se reporta a un niño de 11 años con una herida dolorosa de 4 meses en el borde posterior de la lengua que apareció tras una mordedura, en el que a la exploración clínica se encontró una lesión amarillenta con zonas enrojecidas, rodeada de un halo blanquecino de bordes redondeados. Para el tratamiento se utilizó LLLT, luego de una semana disminuyó el dolor, el paciente comenzó a comer correctamente, a los 15 días se observó una reducción de los bordes rojizos de la lesión, pasado el mes la lesión había remitido casi por completo. La LLLT se describe como un tratamiento eficaz, no invasivo, reduciendo los síntomas, y mejorando la calidad de vida del paciente al promover la curación de las lesiones.

Recurrent aphthous stomatitis (minor, major or herpetic) is one of the most frequent bucodental diseases, of multifactorial etiology and with genetic predisposition. The diagnosis of this pathology is clinical, and based on the clinical history it can be discriminated with other ulcerative pathologies. Low power laser therapy (LLLT) is proposed as a non-invasive treatment, acting as a cellular photo modulator, which reduces pain, inflammation, and stimulating tissue regeneration, preventing damage. This article reports an 11-year-old boy with a 4-month-old painful wound on the posterior edge of the tongue that appeared after a bite, in which clinical examination revealed a yellowish lesion with reddened areas, surrounded by a whitish halo with rounded edges. LLLT was used for the treatment, after one week the pain decreased, the patient started to eat properly, after 15 days a reduction of the reddish edges of the lesion was observed, after one month the lesion had almost completely remitted. LLLT is described as an effective, non-invasive treatment, which reduces symptoms and improves the patient's quality of life promoting the healing of the lesions.

Systemic immune inflammation index in patients with recurrent aphthous stomatitis / Índice de inflamação imune sistêmica em pacientes com estomatite aftosa recorrente

Abstract Objectives: Recurrent Aphthous Stomatitis (RAS) a chronic idiopathic oral mucosal disease. But yet the etiology and pathogenesis of RAS are not exactly known, it is thought that inflammation play an important role in the pathogenesis. The aim of this study is to demonstrate the role of systemic inflammation among the possible etiological factors of RAS and to find the possible diagnostic correlation between Systemic Immune Inflammation Index (SII). Methods: Patients who were consulted the otolaryngology outpatient clinic and diagnosed with RAS between 2019-2021 were retrospectively analyzed. Neutrophil/Lymphocyte Ratio (NLR), Platelet/Lymphocyte Ratio (PLR) and SII values were calculated based on the results of complete blood count. Demographic and hematological parameters between control and RAS groups were compared. The statistical significance level was considered as <0.05. Results: There was no statistically significant difference between the control and RAS groups in terms of sex and age distributions (p = 0.566 and p = 0.173, respectively). SII, NLR and PLR values were significantly higher in the RAS group compared to the controls (p < 0.001, p < 0.001 and p = 0.001, respectively). A very strong correlation between SII and NLR, moderately strong correlation between SII and PLR and moderate correlation between NLR and PLR values were detected (respectively ρ: 0.813, 0.719, 0.532; p-values <0.001). Conclusion: SII, NLR and PLR has significantly higher levels in the RAS group compared to the control group, that it supports the role of systemic inflammation in the etiopathogenesis of RAS. In addition, the results show that SII is a valuable marker for inflammation. Level of evidence: 4. HIGHLIGHTS RAS is a chronic, idiopathic, ulcerative oral mucosal disease. SII is a new and inexpensive biomarker that can easily be calculated using the platelet, neutrophil, and lymphocyte count. SII may be a valuable marker to demonstrate the role of systemic inflammation in RAS etiopathogenesis. Vascular, thrombotic, and inflammatory processes are thought to have a role in RAS activation.

Resumo Objetivo: A estomatite aftosa recorrente (EAR) é uma doença crônica idiopática da mucosa oral. Embora sua etiologia e patogênese não sejam totalmente conhecidas, acredita-se que a inflamação possa desempenhar um papel importante. O objetivo deste estudo é demonstrar o papel da inflamação sistêmica entre os possíveis fatores etiológicos da estomatite aftosa recorrente e encontrar uma possível correlação diagnóstica com o índice de inflamação imunológica sistêmica, SII. Método: Foram analisados retrospectivamente pacientes avaliados no ambulatório de otorrinolaringologia e diagnosticados com estomatite aftosa recorrente entre 2019-2021. A relação neutrófilos/linfócitos, a relação plaquetas/linfócitos e os valores de SII foram calculados com base nos resultados do hemograma completo. Parâmetros demográficos e hematológicos dos grupos controle e de pacientes foram comparados. O nível de significância estatística foi considerado como <0,05. Resultados: Não houve diferença estatisticamente significante entre os grupos controle e com estomatite aftosa recorrente quanto à distribuição por sexo e idade (p = 0,566 e p = 0,173, respectivamente). Os valores de SII, a relação neutrófilos/linfócitos e a relação plaquetas/linfócitos foram significantemente maiores no grupo de pacientes em relação aos controles (p <0,001, p <0,001 e p = 0,001, respectivamente). Foi detectada uma correlação muito forte entre SII e relação neutrófilos/linfócitos, uma correlação moderadamente forte entre SII e relação plaquetas/linfócitos e uma correlação moderada entre valores da relação neutrófilos/linfócitos e relação plaquetas /linfócitos (ρ: 0,813, 0,719, 0,532 respectivamente; p-valores <0,001). Conclusão: SII, relação neutrófilos/linfócitos e relação plaquetas/linfócitos apresentam níveis significantemente maiores no grupo com estomatite aftosa recorrente quando comparados ao grupo controle, o que corrobora o papel da inflamação sistêmica na sua etiopatogênese. Além disso, os resultados mostram que o SII é um marcador inflamatório valioso. Nível de evidência: 4. HIGHLIGHTS A estomatite aftosa recorrente é uma doença ulcerativa crônica idiopática da mucosa oral. O SII (do inglês Systemic Immune Inflammation Index) é um biomarcador novo e de baixo custo que pode ser facilmente calculado que usa a contagem de plaquetas, neutrófilos e linfócitos. O SII pode ser um marcador valioso para demonstrar o papel da inflamação sistêmica na etiopatogênese da estomatite aftosa recorrente. Acredita-se que processos vasculares, trombóticos e inflamatórios tenham um papel na ativação da estomatite aftosa recorrente.

Tratamiento de la estomatitis aftosa recurrente en pacientes inmunocomprometidos. Revisión sistemática / Treatment of recurrent aphthous stomatitis in immunocompromised patients. Systematic review

RESUMEN Fundamento: Aunque la estomatitis aftosa recurrente no tiene una etiología bien definida porque es una enfermedad multicausal, se ha reconocido que las interacciones o el debilitamiento del sistema inmunitario, contribuyen principalmente a la magnitud del proceso patológico. Las propuestas de tratamiento en pacientes inmunocomprometidos son diversas y por lo general se centran en alteraciones inmunológicas específicas. Objetivo: Evaluar el efecto clínico de los tratamientos propuestos para la estomatitis aftosa recurrente en pacientes inmunocomprometidos. Metodología: La búsqueda se realizó en las bases de datos PubMed/Medline y Cochrane. Se incluyeron ensayos clínicos que tuviesen entre sus variables de respuesta principales: Cicatrización de la úlcera aftosa, tiempo de cicatrización, de recurrencia e intensidad del dolor y entre las variables secundarias: Los efectos adversos y los síntomas. La extracción de datos se realizó de manera independiente por los autores. Se aplicó la metodología por la colaboración Cochrane para evaluar el riesgo de sesgo en cada uno de los estudios. Resultados: Se incluyeron 11 ensayos clínicos (8 controlados) publicados entre 1995 y 2020 y que aportan resultados de la eficacia de varias intervenciones terapéuticas: talidomida (4), irsogladine (2), rebamipida (1), láser de diodo (1), cápsulas de Omega-3 (1), vitamina B 12 (1), Complejo B (1). Seis de estos estudios incluyeron pacientes con la forma menor de estomatitis aftosa recurrente. El periodo de seguimiento estuvo entre los 14 y 360 días. Conclusiones: La talidomida puede ser eficaz en el alivio de los síntomas, la cicatrización y remisión de las lesiones, el diodo de láser y vitamina B12 en la disminución de la intensidad del dolor.

ABSTRACT Background: Although recurrent aphthous stomatitis does not have a well-defined etiology due to it is a multicausal disease, it has been recognized that the interactions or the weakening of the immune system, contribute mainly to the magnitude of the process pathological. Treatment proposals in immune compromised patients are diverse and they usually focus on specific immunological alterations. Objective: To evaluate the clinical effect of the proposed treatments for recurrent aphthous stomatitis in immunocompromised patients. Methodology: The search was performed in the PubMed/Medline and Cochrane databases. Clinical trials were included that could have among their main response variables: Aphthous ulcer healing, healing time, recurrence and pain intensity and among the secondary variables: Adverse effects and symptoms. data extraction was done independently by the authors. The methodology was applied by Cochrane collaboration to assess the risk of bias in each of the studies. Results: 11 clinical trials (8 controlled) published between 1995 and 2020 and that provided the results of the efficacy of various therapeutic interventions: thalidomide (4), irsogladine (2), rebamipide (1), diode laser (1), Omega-3 capsules (1), vitamin B 12 (1), Complex B (1). Six of these studies included patients with the minor form of stomatitis recurrent aphthous. The follow-up period was between 14 and 360 days. Conclusions: Thalidomide may be effective in relieving symptoms, healing and remission of the lesions, the laser diode and vitamin B12 in the decrease of the intensity of the pain.

Effect of Dentoxol® in the treatment of recurrent mild aphthous ulcers. A prospective observational pilot study

ABSTRACT: Background: Recurrent aphthous stomatitis (RAS) is the most common oral ulceration. Its prevalence in the general population varies between 5% and 60%, and during the acute period, it causes pain and interferes with basic activities, such as eating, swallowing and talking. Dentoxol® is a medical mouthrinse that cleans, moisturizes and lubricates the mouth, mechanically stimulating local epithelial regeneration. The aim of this study was to evaluate the efficacy of Dentoxol® in improving the general state of patient with minor RAS using two different treatment schemes. Material and methods: Thirty-nine patients with RAS were recruited in a prospective observational pilot study. Two dosing regimens, 5 ml of Dentoxol® twice daily and 5 ml of Dentoxol® three times daily were evaluated. Results: Efficacy to improve the general state was significant superior in "Three time daily" group compared with "twice daily" at 72 h (66% vs 33% respectively). No pain was reported in approximately 90% of cases at 96 h of use in both group without significant differences between the groups in any evaluation time-point. Conclusion: Despite the limitations of these preliminary data, Dentoxol® shows promising beneficial properties for the management of minor RAS.

The Clinical Efficacy of Minocycline Mouth Rinse on Recurrent Aphthous Stomatitis—A Randomized Controlled Trial

Introduction: Recurrent aphthous stomatitis (RAS) is one of the most common ulcerative diseases affecting the general population. The present study aimed to evaluate the clinical efficiency of 0.5% minocycline mouth rinse prescribed along with the topical anesthetic gel and vitamin supplement over the topical anesthetic gel and vitamin supplement prescribed alone for treating RAS. Materials and Methods: A total of 60 participants were randomly divided into two groups—experimental group: 0.5% minocycline mouth rinse prescribed along with vitamin supplement and topical anesthetic gel; and control group: vitamin supplement and topical anesthetic gel alone. The pain symptoms were evaluated using the VAS scores at baseline and first follow?up visits. The data were analyzed using Student’s t test. Results: A significant reduction in the pain scores was observed in participants using the 0.5% minocycline mouth rinse prescribed along with vitamin supplement and topical anesthetic gel on the first follow?up visit (P = < 0.001). Conclusion: The 0.5% minocycline mouth rinse prescribed along with vitamin supplement and topical anesthetic gel had shown more reduction in the pain symptoms when compared to topical anesthetic gel and vitamin supplement prescribed alone for the treatment of RAS.

Neural network analysis of the correlation between malnutrition-induced stomatitis and vitamin B12 and folic acid / 口腔疾病防治

Objective@# A model was built by neural network analysis to study the relationship between different degrees of vitamin B12 and folic acid deficiency and malnutrition-induced stomatitis.@*Methods@# Data from 30 healthy volunteers and 30 patients with malnutrition-induced stomatitis were collected. The distribution of lesions, the number of affected sites and clinical manifestations were recorded, and the severity was scored. The levels of vitamin B12 and folic acid in the peripheral blood of the two groups were simultaneously measured. The SPSS software was used to analyze the correlation between vitamin B12 and folic acid levels in the peripheral blood of patients with malnutrition-induced stomatitis and healthy volunteers, and the MATLAB software package was used to analyze the data via a neural network.@*Results@#The levels of vitamin B12 and folic acid significantly correlated with the grade of malnutrition-induced stomatitis. Simultaneous B12 and folic acid deficiency linearly correlated with the occurrence and severity of malnutrition-induced stomatitis. Based on this correlation, a thermogram model of malnutrition-induced stomatitis was constructed.@*Conclusion@# Malnutrition-induced stomatitis is closely related to vitamin B12 and folic acid deficiency. Their synergistic effect may promote the occurrence and development of malnutrition-induced stomatitis. The construction of the malnutrition-induced stomatitis model aids the targeted etiological treatment of patients with moderate and severe deficiency to prevent malnutrition-induced stomatitis.

Eficacia clínica del extracto de Matico (Piper angustifolium) en la evolución de la cicatrización de heridas por estomatitis aftosa recidivante / Clinical efficacy of Matico extract (Piper angustifolium) in the evolution of wound healing due to recurrent aphthous stomatitis

La estomatitis aftosa recurrente (EAR) es un trastorno ulcerativo doloroso cíclico que comúnmente afecta la mucosa oral. Factores locales y sistémicos como trauma, sensibilidad alimentaria, deficiencias nutricionales, condiciones sistémicas y desórdenes inmunológicos están asociados con el desarrollo de la enfermedad. Debido a las similitudes en las características de las úlceras pépticas y las úlceras aftosas orales, parece razonable suponer que Helicobacter pylori podría desempeñar un papel en el desarrollo de la EAR. Las especies de Piper son plantas aromáticas que se utilizan como especias en la cocina, pero sus metabolitos secundarios también han mostrado efectos biológicos sobre la salud humana. El objetivo del presente estudio fue determinar la relación entre H. pylori y EAR y el efecto cicatrizante del extracto Matico sobre las ulceras bucales. Se reclutó a cuarenta sujetos con EAR. Los participantes fueron asignados al azar al grupo de prueba o al grupo de control. El tamaño y número de las úlceras se registraron el día 1 (valor inicial) y el día 30 (valor final). El tamaño de la ulceras, presencia de pseudomembranas y halos eritematosos fueron estadisticamente significativas en relación a la positividad de H. pylori (p <0,05). No hubo diferencias significativas entre la morfología, número y localización de las aftas (p> 0,05). El grupo que recibió el extracto tuvo un porcentaje de mejoría en la reducción del número de aftas del 65% el día final de evaluación en comparación de sólo un 25% del grupo que no recibió el extracto Matico(AU)

Recurrent aphthous stomatitis (RAS) is a cyclic painful ulcerative disorder that commonly affects the oral mucosa. Local and systemic factors such as trauma, food sensitivity, nutritional deficiencies, systemic conditions, immunological disorders and genetic polymorphisms are associated with the development of the disease. Because of similarities in the characteristics of peptic ulcers and oral aphthous ulcers, it seems reasonable to hypothesize that Helicobacter pylori could play a role in the development of RAS. Piper species are aromatic plants used as spices in the kitchen, but their secondary metabolites have also shown biological effects on human health. The aim of the present study was to determine the relationship between H. pylori and RAS and the healing effect of Matico extract on mouth ulcers. Fuorty subjects with RAS were recruited. The participants were randomly allocated to the test group or the control group. The size and number of ulcers were recorded on day 1 (initial value) and day 30 (final value). The size of the ulcers, the presence of pseudomembranes and erythematous halos were statistically significant in relation to the positivity of H. pylori (p <0.05). There were no significant differences between the morphology, number and location of the canker sores (p> 0.05). The group that received the extract had a percentage improvement in the reduction of the number of canker sores of 65% on the final day of evaluation compared to only 25% of the group that did not receive the Matico extract(AU)

Risk factors for recurrent aphthous stomatitis: a systematic review / Factores de riesgo para la estomatitis aftosa recurrente: revisión sistemática

SUMMARY: The cause and prevention of recurrent aphthous stomatitis (also called aphthous ulcers or canker sores) are still unknown. This may be due in part to ignorance of the risk factors present in susceptible people. In this systematic review (PROSPERO record #CRD42019122214), we show that most of the risk factors for the disease are single nucleotide genetic polymorphisms in genes related to the functioning of immune system (TLR4, MMP9, E-selectin, IL-1 beta and TNF-alpha). Single nucleotide genetic polymorphisms do not constitute a modifiable risk. This indicates that, at least in part, susceptibility to recurrent aphthous stomatitis is hereditary, and that these factors cannot be modified.

RESUMEN: Aún se desconoce la causa y cómo prevenir la estomatitis aftosa recurrente (más conocida como aftas). En esta revisión sistemática (registro PROSPERO #CRD42019122214) mostramos que la mayoría de los factores de riesgo para la enfermedad son polimorfismos genéticos de un solo nucleótido en genes relacionados con el funcionamiento del sistema inmune (TLR4, MMP9, E- selectin, IL-1 beta y TNF-alfa). Los polimorfismos genéticos de un solo nucleótido no constituyen un riesgo modificable.Ello indica que, al menos en parte, la susceptibilidad para las aftas es hereditaria y que esos factores no pueden ser modificados.

Manifestaciones bucales de la enfermedad celíaca y alergia al trigo: Reporte de tres casos y revisión literatura / Oral Manifestations of Celiac Disease and Wheat Allergy: Report of Three Cases and Review of Literature

Resumen: La Enfermedad Celíaca (EC) es una enfermedad sistémica inmunomediada, provocada por el gluten y prolaminas relacionadas, en individuos genéticamente susceptibles. Se caracteriza por manifestaciones clínicas dependientes del gluten, anticuerpos específicos de EC, haplotipos HLA DQ2 o DQ8 y enteropatía. La mayoría de los pacientes son asintomáticos o con manifestaciones leves. Afecta principalmente el sistema gastrointestinal causando síntomas y signos como diarrea, dolor abdominal recurrente y distensión abdominal; además manifestaciones extradigestivas. Los pacientes con EC pueden tener manifestaciones bucales que incluyen estomatitis aftosa recurrente (EAR), hipoplasia del esmalte, glositis atrófica, entre otras. El diagnóstico de EC se basa en la historia clínica, serología, endoscopía e histología. Existen otras entidades que deben diferenciarse de la EC, como la sensibilidad al gluten no celíaca y la alergia al trigo. El objetivo de este trabajo es presentar tres pacientes con antecedentes de EAR y otras manifestaciones clínicas asociadas al diagnóstico precoz de EC y alergia alimentaria.

Abastract: Celiac Disease (CD) is an immune-mediated systemic disease, caused by gluten and related prolamins, in genetically susceptible individuals. It is characterized by gluten-dependent clinical manifestations, CD-specific antibodies, HLA DQ2 or DQ8 haplotypes, and enteropathy. Most patients are asymptomatic or with mild manifestations. It mainly affects the gastrointestinal system causing symptoms and signs such as diarrhea, recurrent abdominal pain and abdominal distension; also extradigestive manifestations. Patients with CD may have oral manifestations that include recurrent aphthous stomatitis (RAS), enamel hypoplasia, atrophic glossitis, among others. The diagnosis of CD is based on clinical history, serology, endoscopy and histology. There are other entities that should be differentiated from CD, such as non-celiac gluten sensitivity and wheat allergy. The aim of this study is to present three patients with a history of RAS and other clinical manifestations associated with the early diagnosis of CD and food allergy.

Impacto de enfermedades orales asociadas a estrés sobre la calidad de vida / Impact on Quality of Life of Oral Diseases Related to Stress

Resumen: Se ha sugerido que enfermedades de la mucosa oral asociadas a estrés impactan negativamente la calidad de vida. Sin embargo, la información no es concluyente. El objetivo fue comparar la calidad de vida asociada a salud bucal en dos grupos: Casos (21 pacientes de una clínica de enseñanza de medicina bucal con diagnóstico de liquen plano oral, estomatitis aftosa recurrente y síndrome de boca dolorosa; Control (42 sujetos sanos) pareados por edad y género. Se aplicó el cuestionario perfil de impacto de salud oral. Resultados: El análisis estadístico mostró que el grupo casos tiene peor calidad de vida (p 0.03) comparado con el de los controles, específicamente en las dimensiones incomodidad psicológica (p 0.027); inhabilidad física (p 0.004); e incapacidad (p 0.002; RM 5.63 IC 1.58-20.80). Se concluye que los sujetos que padecen enfermedades de la mucosa oral relacionada a estrés tienen mala calidad de vida.

Abstract: It has been suggested that oral mucosa diseases related to stress have a negative impact on the quality of life. However, the information regarding which aspects are the most affected is inconclusive. The objective was to compare the quality of life associated with oral health in two groups: Cases formed by 21 patients coming from a teaching clinic, suffering oral lichen planus, recurrent aphthous stomatitis, and burning mouth syndrome; Control formed by 42 healthy subjects matched for age and gender. Oral Health Impact Profile questionnaire was applied. Statistical analysis showed that group Cases has worse quality of life (p 0.03) than the one of controls, specifically on psychological discomfort (p 0.027), physical disability (p 0.004); and handicap dimensions (p 0.002; RM 5.63 IC1.58-20.80). It was concluded that patients suffering oral mucosa disease related to stress showed poor quality of life.

Hyaluronic acid versus dexamethasone for the treatment of recurrent aphthous stomatitis in children: efficacy and safety analysis

The objective of this study was to compare the safety and efficacy of 0.2% hyaluronic acid (HA) topical gel and dexamethasone topical ointment in the treatment of recurrent aphthous ulcers (RAU) in children. This retrospective observational study included 104 patients who had more than two episodes of oral aphthous ulcers per year and were treated with HA (n=52) or dexamethasone (n=52) from August 15, 2014 to September 3, 2018. Therapy efficacy was evaluated based on the ulcer size and pain score before versus 7 days after either therapy. The paired t-test, chi-squared test, and independent t-test were utilized for statistical analyses. There was no significant difference in ulcer size or pain score between the HA and dexamethasone groups, on day 1 or day 7. Both treatments were tolerated well and no side effects were reported. No significant differences in body temperature, respiration rate, pulse, or systolic/diastolic blood pressure were observed between the start (day 1) and end of treatment (day 7), for either treatment. HA and dexamethasone showed similar efficacy in reducing ulcer size and pain scores, and were tolerated equally well in children with RAU. Future high-quality studies with larger numbers of patients are needed to confirm our findings.

Síndrome PFAPA: reporte de un caso clínico / PFAPA syndrome: a case report

El síndrome PFAPA es la entidad más frecuente dentro de los síndromes de fiebres periódicas que pueden manifestarse desde la infancia. Es un síndrome autoinflamatorio caracterizado por una disfunción en las citoquinas, de carácter autolimitado y de etiología desconocida, aunque se han reportado casos de presentación familiar; lo que sugiere la existencia de una base genética de la enfermedad. Se presenta con episodios febriles que suelen acompañarse de aftas orales, adenopatías cervicales, faringoamigdalitis y síntomas constitucionales. En los exámenes de laboratorio es frecuente encontrar elevación marcada de la proteína C reactiva, leucocitosis y aumento de IgG, IgA e IgM. El diagnóstico se realiza utilizando los criterios modificados de Thomas, que incluyen parámetros clínicos, antecedentes y diagnósticos de exclusión. Se presenta el caso de un paciente de 4 años de edad que consultó a un hospital por un cuadro febril, movimientos tónico-clónicos generalizados, desviación de la mirada, sialorrea y relajación de esfínteres. También presentó cefalea de localización frontal y odinofagia. En la cavidad oral se observaron lesiones tipo aftas, y se evidenciaron adenopatías cervicales. El paciente no respondió al manejo con antibióticos, y se observó que cumplía con los criterios de diagnóstico para síndrome PFAPA, luego de descartarse un proceso infeccioso. Se inició terapia con corticoides con respuesta favorable y se concluyó que el paciente tenía un cuadro compatible con síndrome PFAPA.

PFAPA syndrome is the most frequent illness within the syndromes of periodic fevers manifesting during childhood. It is an auto-inflammatory syndrome characterized by cytokine dysfunction, a self-limiting nature, and unknown etiology; family cases have been reported, suggesting the existence of a genetic basis for the disease. PFAPA syndrome is manifested with febrile episodes that are usually accompanied by oral aphthae, cervical adenopathy, pharyngotonsillitis and constitutional symptoms. In laboratory tests, it is common to find marked elevation of C reactive protein, leukocytosis and increased IgG, IgA and IgM levels. Diagnosis is reached by means of the modified Thomas criteria that include clinical parameters, personal and family history, and exclusion diagnoses. The case of a 4-year-old patient who visited the hospital with fever, generalized tonic-clonic seizures and sphincter relaxation is presented. The patient reported frontal headache and odynophagia. Aphthous stomatitis was observed, and cervical adenopathies were evident. The patient did not respond to antibiotic therapy, and met the diagnostic criteria for PFAPA syndrome after an infectious process was ruled out. Corticosteroid therapy was initiated with a favorable response. It was concluded that the patient had a diagnosis compatible with PFAPA syndrome

Estomatitis aftosa recurrente y deficiencias nutricionales: Reporte de tres casos y revisión de literatura / Recurrent Aphthous Stomatitis and Nutritional Deficiencies: Report of Three Cases with Literature Review

RESUMEN Introducción: La estomatitis aftosa recurrente (EAR) es la enfermedad ulcerativa más común que afecta la mucosa oral no queratinizada. La etiología aún se desconoce, pero se han propuesto varios factores locales y sistémicos como agentes causales. Descripción del caso: se informa tres pacientes con presencia de EAR asociada a deficiencias nutricionales, debidas a dietas de restricción alimentaria. El primer caso, una mujer de 19 años con deficiencia de hierro, refirió tomar té verde a diario y consumir poca cantidad de carbohidratos, grasas y carne. El segundo caso, un hombre de 32 años con deficiencia de hierro y vitamina B12 asociada a dieta tipo vegana, aunque a veces si consumía carne. El tercer caso, hombre de 50 años, vegano y exfumador desde hace un año, presentó deficiencia de hierro, vitamina B12 y ácido fólico. En los tres casos un detallado interrogatorio, examen clínico y análisis sanguíneo completo, permitió establecer un adecuado diagnóstico, manejo odontológico y derivación con un nutricionista, con el fin de tratar la patología de base y no sólo brindarles un tratamiento sintomático de las lesiones. Discusión: Ante un cuadro de EAR es recomendable realizar un análisis que incluya hemograma, ácido fólico, hierro y vitamina B12, para descartar posibles causas sistémicas y eventualmente tratarlas. El manejo clínico tiene como objetivo mejorar la función del paciente y la calidad de vida mediante terapias tópicas y sistémicas; sin embargo, es fundamental identificar y controlar los factores causales que contribuyen; así como, la exclusión o tratamiento de la enfermedad sistémica subyacente.

ABSTRACT Introduction: Recurrent aphthous stomatitis (RAS) is the most common ulcerative disease that affects the non-keratinized oral mucosa. The etiology is still unknown, but several local and systemic factors have been proposed as causal agents. Case description: three patients are reported with RAS associated with nutritional deficiencies, due to dietary restriction diets. The first case, a 19-year- old woman with iron deficiency, reported taking green tea daily and consuming a small amount of carbohydrates, fats and meat. The second case, a 32-year-old man with iron deficiency and vitamin B12 associated with vegan diet, although sometimes if he consumed meat. The third case, man of 50 years, vegan and ex-smoker for a year, presented deficiency of iron, vitamin B12 and folic acid. In all three cases a detailed questioning, clinical examination and complete blood analysis allowed to establish an adequate diagnosis, dental management and referral with a nutritionist, in order to treat the underlying pathology and not only provide a symptomatic treatment of the injuries. Discussion: In the setting of RAS, it is advisable to perform an analysis that includes a blood count, folic acid, iron and vitamin B12, to rule out possible systemic causes and eventually treat them. Clinical management aims to improve patient function and quality of life through topical and systemic therapies; however, it is essential to identify and control the causal factors that contribute; as well as, the exclusion or treatment of the underlying systemic disease.

Clinical Characteristics of Patients with Recurrent Aphthous Stomatitis

Recent studies indicate that oral health of the human population, unfavorable trends persist. Despite several researches conducted both in Uzbekistan and abroad, the etiology and pathogenesis of recurrent aphthous stomatitis remains unexplained. The aim of the study is to assess the clinical status of patients with recurrent aphthous stomatitis and develop a method of treatment and prevention. Methods: 106 patients with recurrent aphthous stomatitis were diagnosed. The frequency of exacerbations of RAS ranged from 1 to 4 or more relapses per year, the duration of the disease was more than one year. Results: 72.2% of cases (44 people) were women aged 18-29 years, among men a greater number of complaints - 17 (27.8% cases). Disease duration of recurrent aphthous stomatitis in the patients participating in the study averaged 5.17±0.38 years. 41 people suffered from RAS 1 to 3 years. In 38 patients, the disease duration ranged from 3.1 to 5 years, in 12 people, RAS was observed from 5.1 to 7 years, 15 patients suffered from the pathology under study for more than 7 years. Conclusions: Timely early diagnosis of RAS is not only completely cure for patient, avoid complications, but also revise the low efficiency of traditional methods of the treatment.

RESUMEN La Estomatitis Aftosa, entidad clínica cuya manifestación principal es la aparición de aftas bucales. La búsqueda de medicamentos eficaces para tratarla es un "reto para la comunidad médica". Se realizó un ensayo clínico terapéutico en fase IIb, aleatorizado, se empleó en el diseño experimental pacientes portadores de la enfermedad, que desearon cooperar con el ensayo; el objetivo propuesto fue evaluar la eficacia y seguridad del Propomiel con relación al tratamiento convencional de la Estomatitis Aftosa. La muestra abarcó 102 pacientes, se conformaron dos grupos de 51 pacientes cada uno; en grupo A (experimental) se aplicó propomiel y en grupo B (control) clorhexidina acuosa al 0.2 %. Las variables que se tuvieron en cuenta: grupo de edades, sexo, dolor, cicatrización, tiempo, efecto terapéutico, eventos adversos y severidad de los eventos adversos. Se determinó posible existencia de diferencias significativas entre ambas terapéuticas mediante la prueba de homogeneidad, prueba de X2 o Prueba de probabilidades exactas de Fisher con una confiabilidad del 95 % (p<0,05). Los resultados mostraron mayoría de pacientes de 19-34 años y sexo femenino, así como en ausencia e intensidad dolorosa; tras las 3 primeras aplicaciones el 100 % de los pacientes habían mejorado (grupo experimental) y el 86,27 (grupo control). A los 5 días el 98,04 % de las lesiones habían curado (grupo A) y el 90,20 % (grupo B). No hubo eventos adversos. Se concluye que el tratamiento con propomiel en la estomatitis aftosa demostró eficacia terapéutica y seguridad sin diferencias significativas con respecto a la clorhexidina acuosa al 0.2 %.

ABSTRACT Aphthous stomatitis, a clinical entity whose main manifestation is the appearance of canker sores. The search for effective medications to treat it is a "challenge for the medical community." A randomized phase IIb therapeutic clinical trial was carried out. Patients carrying the disease were used in the experimental design and wished to cooperate with the trial. The proposed objective was to evaluate the efficacy and safety of Propomiel in relation to the conventional treatment of Foot-and-Mouth Disease. The sample comprised 102 patients, two groups of 51 patients each were formed; in group A (experimental) propomiel was applied and in group B (control) 0.2% aqueous chlorhexidine. The variables that were taken into account: age group, sex, pain, healing, time, therapeutic effect, adverse events and severity of adverse events. It was determined possible existence of significant differences between both therapeutics by means of the homogeneity test, X2 test or Fisher exact probability test with a 95% reliability (p <0.05). The results showed the majority of patients 19-34 years of age and female sex, as well as in absence and painful intensity; after the first 3 applications, 100% of the patients had improved (experimental group) and 86.27 (control group). After 5 days, 98.04% of the lesions had healed (group A) and 90.20% (group B). There were no adverse events. It is concluded that propomel treatment in aphthous stomatitis demonstrated therapeutic efficacy and safety without significant differences with respect to 0.2% aqueous chlorhexidine.

RESUMO Estomatite aftosa, uma entidade clínica cuja principal manifestação é o aparecimento de aftas. A busca por medicamentos eficazes para tratá-lo é um "desafio para a comunidade médica". Um ensaio clínico terapêutico randomizado de fase IIb foi realizado, os pacientes portadores da doença foram utilizados no delineamento experimental e desejaram cooperar com o estudo. O objetivo proposto foi avaliar a eficácia e segurança de Propomiel em relação ao tratamento convencional da Febre Aftosa. A amostra foi composta por 102 pacientes, dois grupos de 51 pacientes cada um foram formados; no grupo A (experimental) propomiel foi aplicado e no grupo B (controle) 0,2% de clorexidina aquosa. As variáveis ​​foram consideradas: faixa etária, sexo, dor, cicatrização, tempo, efeito terapêutico, eventos adversos e gravidade dos eventos adversos. Determinou-se a possível existência de diferenças significativas entre as duas terapêuticas por meio do teste de homogeneidade, teste X2 ou teste exato de Fisher com 95% de confiabilidade (p <0,05). Os resultados mostraram a maioria dos pacientes de 19 a 34 anos de idade e sexo feminino, assim como na ausência e intensidade dolorosa; após as 3 primeiras aplicações, 100% dos pacientes melhoraram (grupo experimental) e 86,27 (grupo controle). Após 5 dias, 98,04% das lesões haviam cicatrizado (grupo A) e 90,20% (grupo B). Não houve eventos adversos. Conclui-se que o tratamento com propomel na estomatite aftosa demonstrou eficácia terapêutica e segurança sem diferenças significativas em relação a clorexidina aquosa a 0,2%.

Papel del estomatólogo en el abordaje terapéutico de la aftosis en la enfermedad de Behçet / Role of the stomatologist in the therapeutic approach of aphtosis in Behçet's disease

Introducción: Las aftas y ulceraciones bucales constituyen un motivo frecuente de consulta al estomatólogo. El afta es una forma particular de ulceración bucal. La aftosis se define por el carácter recidivante de aftas múltiples que evolucionan por episodios de 3-10 días y se repiten por lo menos dos veces al año. Objetivo: Abordar los principales aspectos de la Enfermedad de Behçet que podrían ser útiles al estomatólogo. Desarrollo: La enfermedad de Behçet es una vasculitis sistémica inmunomediada caracterizada por una triada característica de lesiones oculares, úlceras orales y genitales recurrentes. La aftosis bucal y la enfermedad de Behçet parecen deberse al mismo mecanismo patogénico, pero aún falta por encontrar las razones por las cuáles la primera se limita a la cavidad bucal y la segunda es sistémica. Debido a que las úlceras orales recurrentes se encuentran en de igual forma en esta enfermedad y la EB, debe considerarse como diagnóstico diferencial de EB. Conclusiones: El papel de los estomatólogos es importante para establecer el diagnóstico de Enfermedad de Behçet, ya que podrían ser los primeros en detectarla. Las úlceras orales recurrentes son un síntoma inicial común de EB. Se requiere un enfoque multidisciplinario para diagnosticar y tratar la enfermedad(AU)

Introduction: Aphthae and oral ulcers are a frequent reason for consulting the stomatologist. Aphthous are a particular form of oral ulceration. Aphtosis is defined by the recurrent nature of multiple aphthae that progress through episodes of 3-10 days and are repeated at least twice a year. Objective: To describe the main aspects of the Behçet disease that could be useful to the stomatologist. Development: Behçet's disease is an immune-mediated systemic vasculitis characterized by a characteristic triad of ocular lesions, recurrent oral and genital ulcers. Oral aphtosis and Behçet's disease seem to be due to the same pathogenic mechanism, but we still have to find the reasons why the former is limited to the oral cavity and the latter is systemic. Because recurrent oral ulcers are found in the same way in this disease and EB, it should be considered as a differential diagnosis of EB. Conclusions: The role of stomatologists is important to establish the diagnosis of Behçet's disease, since they could be the first to detect it. Recurrent oral ulcers are a common initial symptom of EB. A multidisciplinary approach is required to diagnose and treat the disease(AU)
