ABSTRACT

Reações liquenoides orais de contato (RLC) resultam predominantemente por mecanismo de hipersensibilidade da mucosa oral a componentes presentes nas restaurações de amálgama, cujas lesões apresentam características clínicas e histopatológicas seme¬lhantes às do líquen plano oral (LPO) idiopático. A diferenciação entre RLC e LPO idiopá¬tico se faz, essencialmente, pela observação da melhora clínica ou desaparecimento das lesões RLC após a substituição das restaurações de amálgama por materiais restauradores não-metálicos. No presente artigo, 5 casos clínicos de RLC são relatados, enfatizando-se o processo de diagnóstico e tratamento.


Lichenoid contact reactions (LCR) occu r mostly as hypersensitivity reactions of the oral mucosa to components of amalgam restorations, with clinical and histopathologic charac¬teristics similar to those of idiopathic orallichen pia nus (OLP). The differentiation betweenl LCR and idiopathic OLP is made mainly by observation of clinical improvement or disappea¬rance of LCR lesions after replacement of amalgam resolutions by non-metallic restorativel materiais. The present article report 5 cases of LCR, in which the diagnostic approach anol treatment are emphasized.

ABSTRACT

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.

ABSTRACT

Este estudo teve por objetivo investigar a associação transtornos de ansiedade e depressão e do uso de medicamentos com o líquen plano oral (LPO). O grupo de estudo compreendeu pacientes com diagnóstico clínico e histopatológico de LPO, segundo critérios da Organização Mundial de Saúde (WHO, 1978), com ou sem envolvimento cutâneo ou de outras mucosas. Um grupo controle composto por indivíduos sem lesão de líquen plano cutâneo e/ou mucoso, com perfil semelhante ao dos pacientes com LPO em relação ao sexo, idade e cor, foi incluído. Para avaliação de transtornos de ansiedade e depressão foram aplicadas duas escalas de auto-avaliação, respectivamente, o Inventário de Ansiedade Traço-Estado(IDATE-T) e a Escala de Rastreamento Populacional para Depressão – Center for Epidemiologic Studies Depression Scale (CES–D), ambas as escalas validadas internacionalmente. O uso diário de medicamentos foi analisado de acordo com os seguintes critérios: (1) classificação de medicamentos de acordo com o código ATC (Anatomical Therapeutic Chemical – classificação pela OMS, versão 2007), (2)quantidade de medicamentos utilizados – monofarmacia: 1 medicamento, polifarmacia menor: 2 a 4 medicamentos, e polifarmacia maior: 5 ou mais medicamentos, e (3) uso de medicamentos com potencial de induzir reação liquenóide a drogas. Sessenta e três pacientes LPO (média de idade = 54,2 anos, relação mulher/homem 6:1) e 35 do grupo controle (média de idade = 53,3 anos, relação mulher/homem 4:1) compuseram a casuística de pacientes avaliados. Os resultados demonstraram que não houve diferenças estatisticamente significantes...


This study was aimed at investigating the possible association of the anxiety and depression disorders and the use of drugs with the oral lichen planus (OLP). The study group included patients with clinical and histopathologic diagnosis of OLP, according World Health Organization criteria (WHO, 1978), with or without skin and others mucosal involvement. A control group composed of individuals without skin and/or mucosal lichen planus, with similar characteristics to the OLP patients in respect to the sex, age and skin color, was included. For evaluation of anxiety and depression disorders a two self-administered scale the State-Trait Anxiety Inventory(STAI-T) and the Center for Epidemiologic Studies Depression Scale (CES–D) scales were applied, both internationally validated scales. The daily drug in take was analyzed according to the following criteria: (1) classification of drugs according the ATC code (Anatomical Therapeutic Chemical – classification by OMS, 2007 version), (2) amount of drugs used – monopharmacy: 1 drug, minor polipharmacy: 2 a 4 drugs,e major polipharmacy: 5 or more drugs, and (3) use of drugs with potential to inducea lichenoid drug reaction. Sixty-three patients (mean age = 54.4 years, ratio female/male = 6:1) and 35 individuals of control group (mean age = 53.3 years, ratio female/male = 4:1) composed the sample of patients evaluated. The results showed that there were no statistically significant differences (P> 0.05) between the OLP group and the control group with respect to anxiety and depression and the use of drugs. In conclusion, anxiety and depression disorders and the use of drugs seem to play no direct role in the etiopathogenesis of OLP. However, these factors should be considered for general evaluation of OLP patients, mainly for therapeutic purposes...

ABSTRACT

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.

ABSTRACT

: 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
