Burning mouth syndrome: a therapeutic approach involving mechanical salivary stimulation.

OBJECTIVE: The study aimed to evaluate the effects of salivary stimulation therapy on the salivary flow, quality of saliva, and symptoms in patients with burning mouth syndrome (BMS). BACKGROUND: BMS is a chronic disorder characterized by a burning sensation. Some reports have proposed a role for saliva in the pathogenesis of BMS. METHODS: Twenty-six BMS patients underwent treatment with salivary mechanical stimulation. Resting and stimulated saliva were collected before and after therapy. Salivary levels of total protein, brain-derived neurotrophic factor, interleukin-10, tumor necrosis factor-α, interleukin-6, and nerve growth factor were assessed before and 90 days after therapy by enzyme-linked immunosorbent assay. RESULTS: A significant reduction in the burning sensation and number of burning sites as well as an improvement of taste disturbances and xerostomia were observed after therapy. The salivary flow was not significantly modified. However, the therapy resulted in a significant decrease in salivary levels of total protein and an increase of tumor necrosis factor-α. CONCLUSION: Salivary mechanical stimulation therapy is effective in reducing clinical symptoms of BMS.

The impact of burning mouth syndrome on health-related quality of life.

BACKGROUND: Burning mouth syndrome is a chronic disorder that is characterized by a burning sensation and a normal clinical appearance of the oral mucosa. This condition often affects the health-related quality of life in patients. As such, the aim of this study was to compare the health-related quality of life of patients with BMS and healthy controls, using the validated Portuguese versions of the SF-36 and OHIP-49 questionnaires. METHODS: A calculated sample of Brazilian patients with BMS (n = 26) was compared with a control group (n = 27), paired for gender and age. Sociodemographic information and clinical characteristics were obtained, and interviews were conducted using the SF-36 and OHIP-49. To evaluate the normality of the variables, we used the Kolmogorov-Smirnov test. The chi-square test, Fisher exact test and Mann-Whitney U-Test were used to compare sociodemographic and clinical characteristics of individuals with BMS and controls Mann-Whitney U-test were carried out to compare SF-36 and OHIP-49 between BMS patients and controls. The significance level was set at 0.05. To compare the dimensions of the SF-36 and OHIP-49 between BMS patients and controls, we considered Bonferroni correction. So for comparison of the dimensions, the significance level was set at 0.00625 for SF-36 and at 0.00714 for OHIP-49. RESULTS: The clinical and demographic data were similar in both groups (P > 0.05). SF-36 scores were significantly lower in all domains for patients with BMS (P < 0.00625). OHIP-49 scores were higher for individuals with BMS (P < 0.00714). CONCLUSIONS: BMS has a negative impact on the health-related quality of life of individuals, as can be shown by instruments such as the SF-36 and OHIP-49. So, the evaluation of quality of life might be useful for more information about the nature and severity of BMS, to evaluate the effects of treatment protocols, in order to improve their outcomes by means a humanized clinical practice.

Tradução e adaptação transcultural do Interictal Dysphoric Disorder Inventory (IDDI) para o Brasil / Translation and cross-cultural adaptation of the Interictal Dysphoric Disorder Inventory (IDDI)

INTRODUÇÃO: O transtorno disfórico interictal (TDI) se constitui em uma síndrome comportamental descrita principalmente em pacientes com epilepsia. A apresentação pleomófica e inespecífica dos seus sintomas, no entanto, dificulta seu diagnóstico. O Interictal Dysphoric Disorder Inventory (IDDI) é um instrumento recentemente criado com a finalidade de facilitar o diagnóstico do TDI entre os pacientes com epilepsia. OBJETIVO: Tradução e adaptação cultural do Interictal Dysphoric Disorder Inventory (IDD) MÉTODOS: Vinte e um pacientes em acompanhamento regular no ambulatório de Epilepsia do Departamento de Neurologia e Neurocirurgia da Universidade Federal de São Paulo - UNIFESP responderam ao questionário. A versão original foi obtida com um dos autores da escala (Marco Mula) que concedeu a versão original em inglês para a tradução. Dois professores de inglês nativos fizeram a retrotradução. As versões em português e a retrotraduzida foram comparadas à original e após consenso foi obtida a versão final. RESULTADOS: Dos pacientes entrevistados, 17 (81 por cento) eram do sexo feminino, com média de idade de 32,3 anos. Sete completaram o ensino fundamental, enquanto quatro completaram o ensino médio e dois, o ensino superior. Após a aplicação dos 21 questionários apenas a questão D do Apêndice não foi compreendida por três pacientes, tendo sido reescrita. CONCLUSÃO: o ITDI demonstrou-se uma escala de fácil aplicação na população brasileira, constituindo-se de grande utilidade para a avaliação do TDI em pacientes com epilepsia.

INTRODUCTION: Interictal dysphoric disorder (IDD) is a behavioral syndrome described mainly in epileptic patients. The pleomorphic and unspecific nature of its symptoms makes difficult its recognition. The Interictal Dysphoric Disorder Inventory (IDDI) is an instrument specifically created to evaluate IDD symptoms and to facilitate its diagnosis. PURPOSE: Translation and cross-cultural adaptation of the Interictal Dysphoric Disorder Inventory (IDDI). METHODS: Twenty-one patients regularly accompanied in the outpatient epilepsy clinic of Universidade Federal de São Paulo - UNIFESP answered the questionnaire. The original version in English for translation was obtained with one of the authors (Marco Mula). Later, two independent native English-speaking teachers fluent in Portuguese translated this consensus version back into English. Comparison of the back-translation with the original English version showed only a few discrepancies and the English and Portuguese versions were considered conceptually equivalents. RESULTS: Seventeen female (81 percent) and four male (19 percent) answered the questionnaire. The mean age was of 32.3 years and seven had primary school, four had completed secondary and two, higher education. After patients had answered the 21 questionnaires, only three of them did not understand question D of the Appendix section, which had to be rewritten. CONCLUSION: Brazilian patients easily understood the questions of IDDI. We believe that after finishing validation of its psychometric properties this instrument will be very helpful to evaluate the IDD in Brazilian people with epilepsy.
