RESUMO
Resumen Introducción: La osteonecrosis de los maxilares asociada a medicamentos (OMAM) es una patología que involucra la exposición necrótica de hueso maxilar o mandibular, relacionada al uso de fármacos antirresortivos y antiangiogénicos, con una prevalencia de 0,94%-13% en pacientes oncológicos y con osteoporosis que hacen uso de ellos. Objetivo: Determinar la prevalencia de osteonecrosis de los maxilares en pacientes en tratamiento con bifosfonatos intravenosos (BFIV) en el Centro del Cáncer de la Red de Salud UC-Christus, Santiago de Chile. Material y Método: Se analizaron los datos de pacientes que recibieron tratamiento de bifosfonatos intravenoso entre marzo y septiembre de 2016, con seguimiento por los equipos tratantes. Se consideró para la extracción de datos el género, edad, diagnóstico primario, bifosfonato intravenoso utilizado, tiempo de seguimiento, presencia de metástasis óseas y diagnóstico de OMAM. Resultados: Se obtuvo una muestra de 143 pacientes, con una relación hombre:mujer de 1:2; promedio de edad de 63,2 años; 78% de ellos fueron tratados con ácido zoledrónico y un 22% con pamidronato. Del total de pacientes un 1,4% (n = 2) desarrolló OMAM. Ambos casos con diagnóstico de cáncer de mama en tratamiento con ácido zoledrónico, lo que corresponde al 1,8% de los pacientes en tratamiento con este fármaco. Conclusión: Si bien la OMAM es una patología infrecuente, esta se presenta con alta morbilidad y es de manejo complejo. La prevención y tratamiento de focos infecciosos odontogénicos de pacientes antes, durante o después del tratamiento con BFIV es fundamental para prevenir su desarrollo.
Abstract Introduction: Medication-related osteonecrosis of the jaw (MRONJ) is a disease involving exposition of necrotic maxillary and mandibular bone and it's related to antiresorptive and antiangiogenic drugs, with a prevalence that variates from 0,94%-13% in oncologic and osteoporosis patients treated with them. Aim: To determine the prevalence of MRONJ in patients that underwent treatment with intravenous bisphosphonates (IVBP) at Centro del Cancer de la Red de Salud UC-CHRISTUS of Santiago, Chile. Material and Method: Data from patients who received intravenous bisphosphonate treatment between March and September 2016 were analyzed, with follow-ups by their treating teams. Data extraction considered gender, age, primary diagnosis, intravenous bisphosphonate used, follow up time, bone metastases and diagnosis of MRONJ. Results: A sample of 143 patients was obtained with a men:women ratio of 1:2; an average age of 63,2 years, 78% of the patients were treated with zoledronic acid and 22% of the patients with pamidronate. From the total number of patients,1.4% (n = 2) developed MRONJ, both cases had breast cancer as primary diagnosis and in treatment with zoledronic acid, which corresponds to 1.8% of patients being treated with this drug. Conclusion: Although MRONJ is an infrequent disease, it presents high morbidity and complex management. Prevention and treatment of odontogenic infectious foci in patients before, during and after treatment with IVBP drugs is fundamental to prevent this pathology.
RESUMO
Facial injuries are cause of consultation in emergency departments. The maxillofacial region contains several structures that are vital for life. Hence, an early assessment and management of facial injuries is important to avoid their consequential complications and eventual mortality. This article is a review of the literature about the emergency clinical assessment and management of traumatic facial injuries by non-specialists.
