Abstract: introduction: medulloblastomas are malignant, invasive and highly cellular tumours from the cerebellum, rarely seen in adults. we describe the experience in the treatment of this entity in our institution. materials and methods: a retrospective study was made including 11 adult patients with medulloblastomas confined to the craniospinal axis treated between 1984-2010. clinical, radiological and therapeutic data were assessed during the evolution of this entity. results: mean age of patients was 30,2 years (9 women/2 men). over 80% of the patients presented intracranial hypertension, while 54,5% presented cerebellum syndrome. gross total surgical resection was achieved in 8 patients (72,7%) and subtotal resection in the other 3 (27,3%). all patients received craniospinal radiotherapy. after primary surgical resection, 6 patients received chemotherapy with cisplatin (cddp) and etoposide (vp-16). during the follow up period and after a median time of 35,2 months, 4 patients (36,4%) presented with relapse, mainly in the posterior cranial fossa, managed in the majority of cases with surgical resection plus additional chemotherapy. mean survival time was 100,3 months with a 5-and 8-year overall survival rate of 84 and 56% respectively. conclusions: in the treatment of this malignancy, gross surgical resection has a crucial role, followed as soon as possible by oncological therapy, specially radiotherapy and chemotherapy if needed.

Abstract: Introducción: Los meduloblastomas son tumores malignos, invasivos, altamente celulares, del cerebelo, infrecuentes en el adulto. En el presente trabajo describiremos la experiencia en el manejo de esta patología en nuestro centro. Material y métodos: Se trata de un trabajo retrospectivo que incluyó 11 pacientes adultos con diagnóstico de meduloblastoma del eje craneoespinal atendidos entre 1984-2010. Se evaluaron datos clínicos, radiológicos y terapéuticos durante la evolución de la enfermedad. Resultados: La edad media de los pacientes fue 30,2 a os (9 mujeres y 2 varones). Más del 80% de los pacientes manifestaron clínica de hipertensión intracraneal, mientras el 54,5% presentaron síndrome cerebeloso. El grado de resección quirúrgica fue total en 8 pacientes (72,7%) y subtotal en 3 (27,3%). Todos los pacientes recibieron tratamiento radioterápico adyuvante. Posterior a la exéresis tumoral inicial, 6 pacientes recibieron quimioterapia adyuvante con cisplatino (CDDP) y etopósido (VP-16). Durante el seguimiento, después de un tiempo medio de 35,2 meses, se observaron recidivas en el 36,4% de los pacientes (n= 4), con mayor frecuencia en la fosa posterior, empleando en todos ellos tratamiento con cirugía y quimioterapia. El tiempo medio de supervivencia fue 100,3 meses, con un índice de supervivencia estimado a los 5 y 8 a os de seguimiento del 84 y 56 % respectivamente. Conclusiones: La máxima resección quirúrgica forma parte crucial del tratamiento, seguida de adyuvancia oncológica tan pronto sea posible, con radioterapia seguida o no de quimioterapia.

Abstract: this paper shows a measurement methodology of the electromagnetic field produced by radio and telecommunications installations and presents results obtained in the evaluation of 50 measurement sites in the city of cali in colombia. this work was done because people?s concern about proliferation of radio base stations in urban areas, and their fear about the possible dangerous effects of the electromagnetic fields on human health. the evaluation was carried out to determine and quantify the levels of electromagnetic field that exist in the environment of the city. in general, the values found were lower than 0.5% of the limit established by the international commission for non-ionizing radiation protection, icnirp (0.2 mw/cm2). however, in two sites the measured values exceeded this limit.

Abstract: En este artículo se presenta una metodología de medición del campo electromagnético producido por instalaciones de radio y telecomunicaciones y se presentan los resultados obtenidos en la evaluación de 50 sitios en la ciudad de Cali-Colombia. Este trabajo se originó por la preocupación pública causada por la proliferación de estaciones base de telefonía celular en el ámbito urbano y por los temores acerca de los posibles efectos nocivos de los campos electromagnéticos en la salud. La evaluación de los sitios se realizó con el propósito de conocer y cuantificar los niveles de campo electromagnético existentes en el medio ambiente de la ciudad. En general, los valores encontrados fueron inferiores al 0.5% del límite establecido por la Comisión Internacional para la Protección de las Radiaciones No Ionizantes, ICNIRP (0.2 mW/cm2). Sin embargo, en dos casos los niveles encontrados superaron dicho límite.
