First true initial ictal SPECT in partial epilepsy verified by electroencephalography
Jesús Pastor,Luis Domínguez-Gadea,Rafael G Sola,Virgilio Hernando
Neuropsychiatric Disease and Treatment , 2008,
Abstract: Jesús Pastor1, Luis Domínguez-Gadea2, Rafael G Sola3, Virgilio Hernando3, María Luisa Meilán4, Eva De Dios4, José Luis Martínez-Chacón4, Marcos Martínez51Clinical Neurophysiology; 2Nuclear Medicine; 3Neurosurgery; 4Anaesthesiology and Reanimation; Hospital Universitario “La Princesa”, Madrid, Spain; 5Anaesthesiology and Reanimation, Cardiovascular Unit of Adults, Hospital Ramón y Cajal, Madrid, SpainAbstract: Drug-resistant epilepsy can sometimes be treated by surgery. In these cases, an accurate identification of the epileptogenic area must be addressed before resection. Ictal SPECT is one of the presurgical evaluations that can be performed, but usually, the increase in the regional cerebral perfusion observed is produced by diffusion of ictal activity. Here we describe a patient studied with v-EEG and foramen ovale electrodes that suffered a seizure after intravenous infusion of etomidate. The sequence of etomidate administration, followed by radiotracer and seizure was good enough for us to suspect that a true initial ictal SPECT was observed. We have implemented a kinetic model with four compartments, previously described (Andersen 1989), in order to estimate the fraction of hydrophilic radiotracer in the brain during the pre-ictal and ictal periods. This model has shown that the fraction of hydrophilic radiotracer during the seizure into the brain would be between 18.9% and 42.3% of total infused. We show the first true initial ictal SPECT demonstrated by bioelectrical recordings of the brain activity, obtained by a correct succession of events and compatible with theoretical data obtained from the kinetic model.Keywords: etomidate, foramen ovale electrodes, mathematical model, temporal lobe epilepsy
Long-axis rotational volvulus in an ileal J-pouch anal anastomosis: A preventable rare complication  [PDF]
Virgilio V. George, Alyssa Fajardo
Case Reports in Clinical Medicine (CRCM) , 2014, DOI: 10.4236/crcm.2014.31007

Puropose: This study was designed to report a very rare long-term complication of ileal-Jpouch anal anastomosis: An 180 degree longaxial rotational volvulus causing J pouch obstruction. Methods: An Ovid and Medline search using the following keywords was performed: J pouch ileoanal anastomosis, J-pouch ileoanal anastomosis complications, J-pouch volvulus, J-pouch complications, restorative proctocolectomy complications, and restorative proctocolectomy volvulus. One J-pouch ileoanal anastomosis 180° volvulus report was found [1]. Result: We describe a long-axis 180° rotational volvulus complication of a J-pouch ileoanal anastomosis. The J pouch was performed three years prior after the laparoscopic total proctocolectomy for chronic ulcerative colitis. Pouch excision and new ileoanal J-pouch surgery were then performed along with pexy using alloderm mesh placement with excellent outcomes. Conclusion: Long-axis 180° rotational volvulus is a rare complication of a J-pouch ileoanal anastomosis. Pouch dysfunction after a long-axis rotational volvulus is an uncommon cause of acute abdomen. Lack of adhesions and pouch size are risk factors for the pouch torsion. Prompt diagnosis and treatment are essential for the pouch salvage. Simple abdominal x-ray, barium enema and CT scan represent important tools for diagnosis. Salvage surgery should be performed even if detorsion and decompression of the affected bowel are achieved. Surgery has excellent outcomes if performed after the prompt diagnosis. Pouch pexy should be done to prevent recurrent volvulus.

Anales Venezolanos de Nutrición , 2005,
Abstract: abstract it is particularly relevant to note that in this first forum of fundación bengoa, three giants in the area of nutrition of latin america---josé maria bengoa, werner jaffe and nevin scrimshaw-are present. the need of a space for the open discussion of issues and opinions of venezuelans of different tendencies, free of bureaucracy and red tape is acknowledged. various nutritional problems are presented with a special emphasis on the most vulnerable groups, related to general and specific deficiencies, and the need for a permanent forum of discussion on its origins, characteristics and possible solutions. the presence of a strong socioeconomic gradient in the modulation of these problems is evident and has resulted in important contrasts in the growth and development of different social strata. fundación bengoa will continue to present proposals of policies, strategies and actions as a result of a multidisciplinary, highly technical and socially committed group. in this opportunity we acknowledge the generosity of all the contributors of the presentations and collaborators for this forum.
Níveis de análise da ancoragem das representa??es sociais da inteligência e do seu desenvolvimento: Das posi??es sociais objectivas às identidades sociais
Análise Psicológica , 1997,
Abstract: this research try to answer to two relevant problems in the field of the empirical productions about the relationships between social representations of intelligence an development and social identities. the first problem concerns to different levels of the social representations anchorage: on socio-educational objective insertions, which are very common taken as social identities (snelmman and raty, 1995, for example), and on social identities operationalized in terms of selfcategorization and identification to relevant categories. the second problem concerns to the predictive level of the refereed objective social insertions and social identities in what concerns to the representational answers. taking the profession (teachers versus non teachers) and the motherhood status (mothers versus non mothers) as independent variables, we analyse the sociological anchorage level. we analyse the psicosociological anchorage proceeding by the selfcategorization and identification measures to the categories ?teacher? and ?mother?. results shows differences between the two levels of anchorage. to answer to the second problem , we conduct a multiple regression analysis and the results shows that the stereotypes and selfcategorizations explain more variance of the representational answers than the objective insertions in socio-educational space.
Escola e representa??es sociais da inteligência
Análise Psicológica , 1999,
Abstract: in this article, the author proceed to a review of researches on social common sense theories about intelligence - a number of them with reference to the social representations theory - and its articulations with school dynamics. the researches are analysed following the sociogenetic and the ontogenetic dimensions of the common sense theories about intelligence. finally, the theory of the personal conceptions of intelligence, developed by carol dweck, it is also analysed, and some conclusions of a interesting portuguese research, articulating ontogenetic and sociogenetic factors of this kind of lay theories, are refereed.

Cambios en el mercado laboral urbano medidos a través de la esperanza de vida activa
Virgilio Partida
Papeles de población , 2000,
Abstract: Este trabajo tiene como objetivo analizar el cambio reciente en los mercados de trabajo urbanos, bajo un enfoque de transiciones, es decir, mediante los movimientos que los individuos realizan entre actividad e inactividad, entre el empleo formal, el informal y el desempleo abierto. Se utilizan los datos de la Encuesta Nacional de Empleo Urbano (ENEU), la única fuente de datos tipo panel que nos permite contabilizar los movimientos de la población económicamente activa e inactiva. Dentro de la gama de indicadores que hacen posible analizar los cambios recientes en el empleo urbano, se selecciona las esperanzas de vida activa, que tienen la virtud de condensar la edad de la inserción de la población en la actividad económica. El estudio parte de la estrategia de descomponer el cambio temporal en las esperanzas de vida en tres factores: mortalidad, propensión a insertarse en la actividad y cambio en los mercados de trabajo.

Authenticity and inauthenticity of religion from Heideger's standpoint
Cesarone Virgilio
Theoria, Beograd , 2009, DOI: 10.2298/theo0902105c
Abstract: This work aims to investigate the possibility of critiquing a religion with regard to its authenticity/inauthenticity. Where this possibility is found to exist, Heiddeger's existential analytic will be employed to understand the phenomenon of religion. Ultimately, the criteria of existential analytic themselves will be put under scrutiny.
El espa ol en la construcción del Espacio Iberoamericano
Virgilio Zapatero
Quórum : Revista de Pensamiento Iberoamericano , 2007,
Abstract: El Estado, en otros tiempos omnipotente, se ve obligado hoy a devolver poderes a nuevas organizaciones supraestatales. La Unión Europea es un buen ejemplo y se va a dar un creciente impulso de regionalización iberoamericana. La propuesta de avanzar en la creación de un Espacio Iberoamericano del Conocimiento (EIC), cuyo impulso definitivo fue la Cumbre de Salamanca de 2005, es el leitmotiv de este artículo, que analiza el Documento de Montevideo, el papel de Espa a en EIC, la necesidad del espa ol como lengua para la ciencia y la creación de una web iberoamericana del conocimiento.
