    <dcterms:abstract><![CDATA[<p><strong>RESUMEN</strong><br /> <strong><br /> Objetivo.</strong> Describir los detalles t&eacute;cnicos del abordaje transcigom&aacute;tico, mostrando su utilidad.<br /> <strong>Descripci&oacute;n.</strong> La incisi&oacute;n se extiende desde el borde inferior del arco cigom&aacute;tico hasta la l&iacute;nea pupilar contralateral. Luego se realiza una disecci&oacute;n subgaleal e intedascial. Posteriormente, el arco cigom&aacute;tico es seccionado en forma vertical en dos sectores, y luego movilizado inferiormente junto con el m&uacute;sculo masetero. El paso siguiente es realizar una craneotom&iacute;afronto-temporo-esfenoidal, de tal manera que la parte anterior de la duramadre temporal queda totalmente expuesta. As&iacute;, las posibilidades quir&uacute;rgicas son las siguientes: a) acceso intradural a la fosa media; b) acceso intradural pretemporal a las cisternas basales; c) acceso intradural transtemporal y d) acceso extradural a la fosa media.<br /> <strong>Conclusi&oacute;n.</strong> El abordaje transcigom&aacute;tico ofrece una excelente exposici&oacute;n al piso de la fosa media y a la pared lateral del seno cavernoso (tanto intradural como extradural). Adem&aacute;s, combinado con una v&iacute;a pretemporal, permite un muy buen acceso a la cisterna interpeduncuiar; adem&aacute;s, utilizando un abordaje transtemporal, ofrece una buena visi&oacute;n de la regi&oacute;n insular.<br /> <strong>Palabras clave:</strong> abordaje transcigom&aacute;tico, anatom&iacute;a, arco cigom&aacute;tico, base de cr&aacute;neo.</p>]]></dcterms:abstract>

<p><strong>ABSTRACT</strong><br /> <strong>Objective.</strong> To present our experience in the management of cerebral low-grade gliomas (LGGs) in children.<br /> <strong>Material and Method. </strong>Between January 1982 and December<br /> 2008 we operated cerebral LGGs in 30 children under 15 years of age, (17 males, 13 females).<br /> <strong>Results.</strong> Setzures were the main clinical manifestation in 24 (80%) children. MRI was the preferred diagnostic method. Twenty:four patients underwent pre-operative surface electroencephalogram (EEG) recording. Fibrillary astrocytomas and oligodendrogliomas were the mostfrequent varieties (28 / 30). Regarding treatment modality, 19 patients underwent only tumor resection, while 8 patients underwent tumor resection associated to radiotherapy. Two children were treated with Interstitial Stereotactic Radiosurgery or Brachytherapy with 1125. One patient was treated the hydrocephalus only. Mortality: 3 patients (10%): one case because of sepsis due to shunt infection, 6 years and 6 months after surgery; the other case because of myocardial infarction 22 years after surgery; and in the third case, the patient died because of a twice-recurrent tumor,<br /> evolving from grade II to 111 andfinally IV (secondary glioblastoma multiforme), 10 years and 5 months after first surgery. From the 27 (90%) surviving children, 25 (83,3%) are seizure free, 2 (6,6%) have sporadic seizures with abnormal EEG tracing. Survival rangesfrom 5 months to 25 years, with a mean of 12 years and seven months.<br /> <strong>Conclusion. </strong>The extent of surgical resection is the most important prognosticfactor in pediatric LGGs. Radiation therapy and chemotherapy are generally used in the settings of incomplete resection and recurrent disease. Interstitial stereotactic radiosurgery is a good therapeutic option.<br /> <strong>Key words:</strong></p>]]></dcterms:abstract>

    <dcterms:abstract><![CDATA[<p><strong>RESUMEN</strong><br /> <strong>Objetivo.</strong> Realizar una revisi&oacute;n sobre los aspectos cl&iacute;nicos, radiol&oacute;gicos, histol&oacute;gicos y evolutivos en una serie de pacientes con variedades at&iacute;picas y anapl&aacute;sicas de meningiomas craneales.<br /> <strong>Material y m&eacute;todo. </strong>Se realiz&oacute; un estudio retrospectivo de seis pacientes con diagn&oacute;stico de meningiomas at&iacute;picos y anapl&aacute;sicos tratados durante el periodo 2003-2008. Se analizaron las variables: edad. sexo,forma de presentaci&oacute;n, localizaci&oacute;n tumoral, estudios imagenol&oacute;gicos, t&eacute;cnica quir&uacute;rgica, tratamientos oncol&oacute;gicos complementarios y evoluci&oacute;n.<br /> <strong>Resultados.</strong> La edad media fue de 63 a&ntilde;os (rango 58-68). La relaci&oacute;n hombre/mujer fue de 4:2. La cefalea y las crisis comiciales fueron las formas de presentaci&oacute;n m&aacute;s habituales; la localizaci&oacute;n m&aacute;s frecuente fue a nivel de la convexidad cerebral. Todos los pacientes fueron estudiados con tomografia y resonancia magn&eacute;tica. En cuatro pacientes se realiz&oacute; resecci&oacute;n grado II de Simpson y en los dos restantes resecci&oacute;n grado I. Todos los pacientes fueron tratados con radioterapia postoperatoria.<br /> <strong>Conclusi&oacute;n.</strong> Los meningiomas at&iacute;picos y anapl&aacute;sicos constituyen entre el 5-10% de los meningiomas. A diferencia de las variantes benignas, son m&aacute;s frecuentes en hombres y a nivel de la convexidad cerebral. El tratamiento de elecci&oacute;n es la ex&eacute;resis quir&uacute;rgica completa seguida de radioterapia. A pesar del tratamiento instaurado, poseen un alto &iacute;ndice de recidivas aumentando as&iacute; la mortalidad.<br /> <strong>Palabras clave: </strong>meningioma at&iacute;pico, meningioma anapl&aacute;sico, radioterapia, recidiva, evoluci&oacute;n.</p>
<p><strong>ABSTRACT</strong><br /> <strong>Objective: </strong>This study aims to be a review about cl&iacute;nica!, radiologic, histological and prognostic factors of a patient's series with atypical or anaplastic meningiomas.<br /> <strong>Methods</strong>: We performed a retrospective review of six patients treated with atypical or anaplastic meningioma, betuneen 2003 and 2008. We analyzed data concerntng patient's age, sex, cl&iacute;nica! behavior, tumor location, radiological findings, surgical technique, adjuvant treatment and cl&iacute;nica! course.<br /> <strong>Results: </strong>The mean age was 63 years old (range: 58 to 68). Male / female ratio was 4:2. Headache and seizures were the most common presenting symptoms. Wefound cerebral convexity as the predominant site of location. We studied all patients with CT<br /> and MRI. Four patients were under Simpson II resection and the other two Simpson 1. All patients were treated with adjuvant radiation therapy.<br /> <strong>Conclusion: </strong>Atypical and anaplastic meningiomas represent 5-10% of all meningiomas. They have male preponderance and cerebral convexity location predominante. Gross total resection and adjuvant radiation therapy are the best choices in treatment. Despite of treatment, this tumors exhibit high recurrence rates which Mercases mortality.<br /> <strong>Key words:</strong> atypical meningioma, anaplastic meningloma, radiotherapy, recurrence, outcome.</p>]]></dcterms:abstract>

Comienza tratamiento con Vancomicina-Meropenem y se evidencia nueva infecci&oacute;n urinaria por E. Coli, germen tambi&eacute;n cultivado en la colecci&oacute;n purulenta subdural. TAC con contraste: no se evidencian colecciones residuales. A los trece d&iacute;as post operatorios evoluciona con shock s&eacute;ptico secundario a neumon&iacute;a por Acinetobacter, falleciendo a los diecisiete d&iacute;as de internaci&oacute;n en UTI.<br /> <strong>Conclusi&oacute;n.</strong> El empiema subdural es una inusual yfulminanteforma de sepsis intracraneal, con alta tasa de morbi-mortalidad, que requiere r&aacute;pido diagn&oacute;stico, temprana evacuaci&oacute;n, eliminaci&oacute;n delfoco infeccioso de origen y adecuado tratamiento antibi&oacute;tico. Deben tenerse en cuenta las presentaciones at&iacute;picas, caracterizadas por escaso compromiso sist&eacute;mico infeccioso o los casos que presentan el antecedente de trauma de cr&aacute;neo leve y formaci&oacute;n de un hematoma/ higroma subdural que pueden colonizarse e infectarse tras un episodio de bacteremia, organizando una colecci&oacute;n infectada.<br /> <strong>Palabras clave: </strong>abscesos por E.

<p><strong>ABSTRACT<br /> Objective.</strong> To describe a subdural empyema case caused by E. Coli Description. The clinical records and images of a patient with a subdural empyema by E. Coli was reviewed, treated at the Spanish Hospital from Buenos Aires city in 2010. A 84 y ear old female with recurrent urinary tract infections admittedfor mild TBI, without neurological deficit. CT: without significant<br /> findings. Urinary infection is found and decided hospital for treatment.<br /> <strong>Intervention.</strong> Two weeks after a new TAC ts performed, showing a laminar hypodense bifrontal collection. A new urinary tract infection appears. At the end of two weeks of treatment, presents a grand mal seizure that become into status epilepticus. CT: right hemispheric hypodense subdural collection. Surgery is performed with purulent subdural evacuation. Starting treatment with vancomycin, meropenem and a new evidente E.<br /> Coli urinary infect&iacute;ons, the germ also cultivated in the subdural purulent. CT with contrast: no evidente of residual collections. At thirteen days after surgery developed septic shock secondary to Acinetobacter pneumonta and died on the seventeenth day of hospitalization in ICU.<br /> <strong>Conclusion. </strong>Subdural empyema is an unusual and fulminant type of intracranial sepsis associated with high morbidity and mortality. The best outcome depends of the fast diagnosis, an early evacuation, elimination of the infection source and a correct antibiotics treatment. Some uncommon presentations must be thought, such as the cases withoutfever / leucocitosis or the cases where the developing of the collection arise from a subdural hematoma / hig roma, infected after a bacteremia event.
