RESUMO

BACKGROUND: The use of osteoclast inhibitors in metastatic bone disease, increase bone mineral density and reduce the risk of fracture, patients with osteonecrosis have been reported after the chronic use of these inhibitors. In our country, the use of osteoclast inhibitors is in the context of osteoporosis and bone metastases, so it is important to describe the incidence of this complication in Mexican population. OBJECTIVE: To describe the incidence of osteonecrosis of the jaws at the Centro Médico Nacional 20 de Noviembre, during the period from January 1st, 2010 to June 1st, 2016. METHODS: This is a retrospective cohort study developed at the Centro Medico Nacional 20 Noviembre, ISSSTE, Mexico. We included all patients who received bisphosphonates or denosumab in the context of metastatic bone disease due to solid tumors and who had osteonecrosis of the jaw. RESULTS: A 802 patients who used bisphosphonates or denosumab in metastatic bone disease (699 bisphosphonates and 103 denosumab). Of these, 28 (3.5%) patients presented osteonecrosis. The median use of zoledronic acid for the presence of osteonecrosis was 25 months (15-49 months) and for Denosumab it was 16 months (11-35 months), without finding significant differences between the use of drugs p = 0.511 and the risk of osteonecrosis. CONCLUSIONS: Drug-induced osteonecrosis has a low incidence in Mexican population, denosumab does not show a greater number of cases of osteonecrosis compared to bisphosphonates; no association was found between functional status, number of metastatic bone sites, nor use of antigenic or tyrosine kinase inhibitors as factor associated with osteonecrosis of the jaws.


ANTECEDENTES: El uso de inhibidores de osteoclastos en la enfermedad metastasica ósea tiene como objetivo aumentar la densidad mineral ósea y reducir el riesgo de fractura. Se han reportado pacientes con osteonecrosis de los maxilares tras el uso crónico de estos inhibidores. En nuestro país, los inhibidores de osteoclastos se usan en el contexto de osteoporosis y de metástasis óseas, por lo que es importante describir la incidencia de esta complicación en población mexicana. OBJETIVO: Describir la incidencia de osteonecrosis de los maxilares en el Centro Médico Nacional 20 de Noviembre, durante el periodo del 1 de enero del 2010 al 1 de junio de 2016. MÉTODO: Estudio de cohorte retrospectiva desarrollado en el Centro Médico Nacional 20 de Noviembre, del Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado, en Ciudad de México. Se incluyeron todos los pacientes que recibieron bisfosfonatos o denosumab con enfermedad metastasica ósea por tumores sólidos, y que presentaron osteonecrosis de mandíbula. RESULTADOS: Se analizaron 802 pacientes que recibieron bisfosfonatos o denosumab en enfermedad metastasica ósea (699 bifosfonatos y 103 denosumab). De ellos, 28 (3.5%) presentaron osteonecrosis. La mediana de uso de ácido zoledrónico para la presencia de osteonecrosis fue de 25 meses (15-49 meses), y para denosumab fue de 16 meses (11-35 meses), sin encontrar diferencias significativas entre ellos (p = 0.511) y el riesgo de osteonecrosis. CONCLUSIONES: La osteonecrosis inducida por medicamentos tiene una baja incidencia en población mexicana. El denosumab no muestra un mayor número de casos de osteonecrosis en comparación con los bisfosfonatos. No se encontró asociación entre el estado funcional, el número de sitios óseos metastásicos ni el uso de antiangiogénicos o de inhibidores de la tirosina cinasa como factor asociado a osteonecrosis de los maxilares.

RESUMO

The present study aimed to assess the efficacy of using botulinum toxin (BTX) in temporomandibular joint disorders, particularly pertaining to myofascial pain from masseter and temporal muscles. The study included 11 patients who were diagnosed with masseter and temporalis myofascial pain. Visual analog scale for pain and pressure algometry were conducted initially, after 1 month of conservative therapy (control group), and after 1 month of BTX type A injections (study group). Data were statistically analyzed (analysis of variance and Wilcoxon's test) to determine intergroup differences. Both conservative therapy and BTX injections showed reduction in pain scores and increase in pain threshold compared with baseline, and statistically significant differences were noted between both groups. Thus, BTX injections appear to be effective in management of chronic myofascial pain targeting masseter and temporalis muscles.

RESUMO

Los tumores malignos de la vaina nerviosa periférica (TMVNP), también llamados neurofribrosarcomas o schwannomas malignos, representan el 10% de todos los sarcomas de tejidos blandos. El tumor usualmente se encuentra en las extremidades inferiores, y solo del 10 al 20% de las lesiones ocurren en la región de cabeza y cuello, convirtiéndolas en una entidad rara. Los neurofibromas son tumores de la vaina nerviosa que aparecen comúnmente en la neurofibromatosis 1 o enfermedad de Von Recklinghausen. Se ha reportado que los individuos con antecedentes familiares de neurofibromatosis 1 tienen un riesgo incrementado de desarrollar TMVNP en el transcurso de sus vidas, sin embargo, esta asociación no se ha confirmado en TMVNP a nivel de los nervios craneales. En este artículo los autores analizaron la literatura actual con respecto a los TMVNP del nervio trigémino, así como la inclusión de un caso inusual que involucra las 3 ramas de dicho nervio (AU)


Malignant peripheral nerve sheath tumours (MPNSTs), also called neurofibrosarcomas or malignant schwannomas, represents 10% of all soft tissue sarcomas. The tumour is usually found in the lower extremities, and only 10 to 20% of all lesions occur in head and neck region, thus making it a rare entity. Neurofibroma is one of the common nerve sheath tumours occurring in the soft tissues, and generally appears in neurofibromatosis 1 or Von Recklinghausen's disease. Individuals with a family history of neurofibromatosis 1 are reported to have an increased risk of developing MPNSTs in their lifetime. However, this association is not seen in MPNSTs of the cranial nerves. In this study, the authors reviewed the current literature on MPNSTs of the trigeminal nerve to analyse the presentations, treatment options, and outcomes for patients with this disease, as well as the report of a case involving the 3 branches of the trigeminal nerve (AU)
