Trismus and oral health conditions during diagnosis of malignant oral neoplasms / Trismo e condições de saúde bucal no diagnóstico de neoplasias malignas da cavidadeoral

Abstract Introduction: Trismus has been considered a late complication of cancer treatment. It can occur prior to treatment, mainly caused by tumor invasion or muscle spasms induced by the presence of the tumor. Objective: In this study, we evaluated the incidence of trismus and its effect on oral health in patients with malignant neoplasms of the oral cavity before performing the cancer treatment. Methods: This review was carried out via interviews, visual clinical inspection and objective measurement of maximal mouth opening in 35 consecutive patients. Trismus was defined as a maximal mouth opening <35 mm. Results: Trismus was observed in 15 patients, with a total incidence of 42%. A high rate of tooth loss was recorded, and trismus association with tooth loss was statistically verified using the Chi-square and Fisher's exact tests, the t-student test and Mann-Whitney non-parametric test. All tests were performed at p < 0.05. Conclusion: Edentulous patients are eight times more likely to have trismus compared to patients that are partially and fully dentate. Trismus was demonstrated to be correlated with tooth loss; however other oral health conditions were not shown to be a modifying factor.

Resumo Introdução: O trismo tem sido considerado uma complicação tardia do tratamento do câncer, pode ocorrer antes do tratamento, causado principalmente por invasão tumoral ou espasmos musculares induzidos pela presença do tumor. Objetivo: Avaliar a incidência do trismo e seu efeito sobre a saúde bucal em pacientes com neoplasias malignas da cavidade bucal antes de se submeterem ao tratamento do câncer. Método: Esta revisão foi realizada por meio de entrevistas, inspeção clínica visual e mensuração objetiva da abertura bucal máxima em 35 pacientes consecutivos. O trismo foi definido como abertura bucal máxima < 35 mm. Resultados: O trismo foi observado em 15 pacientes, com uma incidência de 42%. Uma alta taxa de perda dentária foi registrada e a associação do trismo com a perda dentária foi verificada estatisticamente com os testes qui-quadrado, exato de Fisher, t de Student e não paramétrico de Mann-Whitney. Todos os testes foram realizada com p < 0,05. Conclusão: Pacientes edêntulos são oito vezes mais propensos a ter trismo do que os pacientes parcial e totalmente dentados. O trismo demonstrou estar correlacionado com a perda dentária. Entretanto, as outras condições de saúde bucal não se mostraram um fator modificador.

Validação para a língua portuguesa do Gothenburg Trismus Questionnaire (GTQ) / Validation of the Portuguese version of the Gothenburg Trismus Questionnaire

Atualmente, o Gothenburg Trismus Questionnaire (GTQ) é o único questionário de qualidade de vida específico sobre trismo. A afecção, definida como restrição à abertura da boca, gera prejuízo a atividades habituais como comer, engolir, falar e fazer a higiene oral, trazendo grande desconforto aos pacientes. A tradução de questionários de qualidade de vida desempenha um importante papel no conhecimento da saúde das populações nos diferentes países. O objetivo do presente estudo é apresentar a validação do GTQ para a língua portuguesa, a fim de permitir sua aplicação efetiva nas populações de idioma português. O GTQ foi validado com sucesso para a língua portuguesa conforme os seguintes passos: Tradução, Retradução (back translation), Adaptação cultural e Revalidação.

Currently, the Gothenburg Trismus Questionnaire (GTQ) is the only quality-of-life questionnaire specific for the assessment of trismus. The disease, characterized by limited mouth opening, impairs usual activities such as eating, swallowing, talking, and performing oral hygiene, causing great discomfort to patients. Translation of quality-of-life questionnaires plays an important role in promoting health awareness in the populations of different countries. This study aimed to validate the Portuguese version of the GTQ to allow its effective application in Portuguesespeaking populations. The Portuguese version of the GTQ was successfully validated through the following steps: translation, back translation, cultural adaptation, and revalidation.

Análise epidemiológica da mão queimada no Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo / Epidemiological analysis of the burned hand in the Clinics Hospital, Medical School of São Paulo University

A mão é uma parte do corpo frequentemente acometida em pacientes queimados. Sua alta incidência é reconhecida no mundo todo, assim como o grande impacto na qualidade de vida dos pacientes. Por muitas vezes, seu tratamento é postergado pela presença de graves condições clínicas associadas. Nesse artigo, os autores relatam as características epidemiológicas dos pacientes internados na Divisão de Cirurgia Plástica e Queimaduras do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (São Paulo, Brasil), destacando a importância da mão queimada na população economicamente ativa e sua associação com o grande queimado, dificultando o seu tratamento.

The hand is one region from the human body frequently affected in burnt injuried patients. Its high incidence is not only worldwide recognized, but also its great impact in patients’ quality of life. For many times, its treatment is put off by the presence of associated severe clinical conditions. Here, we report the epidemiological data of inpatient cases from Plastic Surgery and Burn Division, Clinics Hospital, Medical School of São Paulo University (São Paulo, Brazil),highlighting the importance of the burned hand in the economically active population and its association with major burnt patient, complicating its management.
