Orientações odontológicas aos pacientes submetidos à quimioterapia antineoplásica / Dental guidelines for patients undergoing antineoplastic chemotherapy

Objetivo: este trabalho propõe condutas bucais aos pacientes com indicação quimioterápica, a partir de uma revisão de literatura, visto que o paciente é pouco orientado em muitos casos. Material e métodos: a busca foi realizada a partir da base de dados PubMed/Medline. Apenas estudos observacionais e revisões da literatura, em inglês, espanhol e português, publicados entre 2001 e 2019, que abordassem o tratamento antineoplásico e apresentassem complicações bucais foram incluídos. Resultados: dez artigos preencheram os critérios de inclusão. Notou-se que a maioria dos efeitos adversos cessam ao fim da quimioterapia. As principais alterações bucais observadas foram mucosite, xerostomia e candidose. Diversas alternativas terapêuticas se mostraram eficazes, sendo fundamental individualizar o paciente e propor a melhor opção para o quadro específico apresentado. Considerações finais: A participação do cirurgião-dentista na equipe oncológica é extremamente importante, realizando intervenções odontológicas e orientando os pacientes, colaborando para uma melhor qualidade de vida e contribuindo significativamente no prognóstico da doença.(AU)

Objective: This study suggests oral management for chemotherapy patients, through a literature review, considering that patients are poorly instructed in most cases. Material and methods: The search was performed in the PubMed / Medline database. Only observational studies and literature reviews in English, Spanish, and Portuguese, published between 2001 and 2019, which discussed antineoplastic treatment and presented oral complications were included. Results: Ten articles met the inclusion criteria. Most adverse effects were observed to cease at the end of chemotherapy. The main oral changes observed were mucositis, xerostomia, and candidosis. Several therapeutic alternatives seem to be effective, and it is essential to individualize the patient and propose the best option for the specific condition. Final considerations: The participation of dentists in the cancer team is extremely important for performing dental interventions, guiding patients, helping to provide a better quality of life, and contributing significantly to the prognosis of the disease.(AU)

Estudio comparativo: prevalencia patologías bucales en pacientes pediátricos oncológicos 1997-2007 / Comparative study: oral pathologies prevalence in pediatric oncology patients 1997- 2007

Los pacientes pediátricos oncológicos con frecuencia presentan lesiones orales debido a su neoplasia o como efecto colateral del tratamiento. El objetivo de este estudio fue comparar la prevalencia de patologías de la mucosa oral en niños con cáncer que fueron hospitalizados y tratados con quimioterapia en el Hospital Regional de Concepción, en los años 1997 y 2007. Se realizó un estudio descriptivo retrospectivo longitudinal en datas de 148 pacientes (74 cada año) con patologías neoplásicas en tratamiento con quimioterapia (Leucemias, linfomas, tumores del Sistema Nervioso Central y otros), registrando sus datos generales y la patología bucal (mucositis (M), candidiasis (C), lesiones por Virus Herpes tipo 1 (VHS) y síndromes hemorragíparos (H) . Los datos se resumieron en tablas anuales y fueron sometidos a análisis estadísticos. Se encontró una disminución significativa del número de pacientes con patologías bucales en el año 2007 en relación al año 1997 (P<0.05, Tet de Fisher). Además se encontró una tendencia a la baja en los pacientes con candidiasis y con mucositis en el año 2007 en comparación con 1997. Es necesario seguir estudiando medidas para prevenir, diagnosticar y/o tratar tempranamente las patologías orales de los pacientes en tratamiento antineoplásico.

Pediatric oncology patients frequently have oral lesions due to malignancy or as a side effect of treatment. The aim of this study was to compare the prevalence of oral pathologies in oncology patients hospitalized and treated at the Regional Hospital of Concepción, Chile, in the years 1997 and 2007. A retrospective study was carried out in 74 patients each year. Patients suffered from acute lymphoblastic leukemia, acute myeloblastic leukemia, central nervous system tumors, lymphomas and other neoplasms. General data (age, gender, oncologic disease) and presence of oral pathologies (candidiasis, mucositis post-chemotherapy, herpetic lesions and hemorrhage) were obtained from their clinical records. Data was analyzed for statistical differences. A significant reduction in the number of patients with oral pathologies was found in 2007 in comparison to 1997 (P<0.05, Fisher´s test). In addition, candidiasis and oral mucositis showed less prevalence in 2007 as compared to 1997, although no significant differences were found. For the relevance of oral pathologies in the chemotherapy it´s important to continue studies about prevention, early detection and treatment of oral pathologies.

Itraconazole for treatment of oral candidosis in pediatric cancer patients.

Oral candidosis commonly occurs in malignancy children undergoing antineoplastic chemotherapy. Inadequate response to antifungal treatment leads to a risk of disseminated infection. The aim of this study is to evaluate the efficacy and side effects of itraconazole on treatment of oral candidosis. Fourteen children with malignancy undergoing chemotherapy received itraconazole 100-200 mg/day for 10 days to treat oral candidosis. The severity of disease was defined as mild and moderate depending on the number of lesions and symptoms. Oropharyngeal lesions and symptoms were recorded initially and daily. Blood chemistries were done on day 0, day 10 and day 16. The overall response rate was 87.5 per cent. The mild group (4 cases) had a response rate of 100 per cent which had lesions and symptoms resolved on day 2 and day 1.5 +/- 0.7 respectively. The moderate group (10 cases) had 8 responders (80%) whose lesions and symptoms resolved on day 6 +/- 2.5 and day 4.1 +/- 2.3 respectively. Side effects and abnormal blood chemistry values. were not seen.

Depresión mayor y salud oral: rol de los fármacos antidepresivos / Major depression and oral health: role of antidepressant agents

La mayoría de los fármacos antidepresivos, así como otras drogas usadas en el manejo de los cuadros depresivos son hiposalivantes. La disminución del flujo salival produce alteraciones en los tejidos blandos y duros de la cavidad oral. Las principales patologías que se han descritos asociadas a hiposialia son las caries dentarias, la candidiasis oral y en algún grado la gingivitis y periodontitis. Adicionalmente, estas patologías pueden verse exacerbadas por el abandono de los hábitos de higiene oral, debido a las alteraciones del ánimo de los pacientes. Algunas de estas infecciones bucales pueden en ocaciones comprometer gravemente la salud general. Dado el mayor riesgo de los pacientes con hiposialia de desarrollar patologías orales, y sus eventuales consecuencias en la salud general, como a nivel del estado sicológico de los pacientes, es que resulta importante reducir en lo posible la incidencia de estas patologías orales en pacientes depresivos, principalmente aquéllos en tratamiento con psicofármacos hiposalivantes
