Abstract: background: hyperamylasemia and acute pancreatitis represent the most frequent major complication after endoscopic retrograde cholangiopancreatography (ercp), developing in 1-30% of cases. objective: to determine the incidence of hyperamylasemia and acute pancreatitis after ercp, and to assess the utility of rectal indomethacin to prevent these events. material and methods: a randomized clinical trial. during a 12-month period 150 patients were included. they were divided up into a study group (n = 75), where 100 mg of rectal indomethacin were administered 2 hours prior to the procedure, and a control group (n = 75), which received rectal glycerin. two hours after ercp serum amylase levels were measured and classified as follows: 0 ≤ 150 iu/l, 1 = 151-599 iu/l, 2 ≥ 600 iu/l. clinical pancreatitis episodes were quantified and classified according to ranson's criteria. results: gender distribution: 100 women and 50 men. mean age: 55.37 ± 18.0 for the study group, and 51.1 ± 17.0 for the control group. a diagnosis of benign pathology was present in 56 (74.7%) cases in the study group, and 59 (78.7%) controls. after ercp 13 (17.3%) patients in the study group and 28 (37.3%) in the control group developed hyperamylasemia (p ≤ 0.05). hyperamylasemia > 600 iu/l was found in 3 patients in the study group, and in 10 in the control group (p = 0.001). mild pancreatitis was detected in 4 (5.3%) patients in the study group, and in 12 (16%) patients in the control group (p = 0.034). there were no deaths or adverse drug reactions. conclusions: rectal indomethacin before ercp decreases the risk of hyperamylasemia and pancreatitis. indomethacine is a feasible, low-cost drug with minimal or nil side effects.
Estado y Seguridad Privada en Costa Rica: Análisis de Coyuntura
Muoz G,Mercedes;
Diálogos Revista Electrónica de Historia , 2011,
Abstract: study of the link between the state and private security companies in costa rica, in order to answer the following questions: how much is invested in the juncture 2006-2008 to keep the offer of this service in some instances of the public sector? how does the accounting reflect the amounts that the state invests on services of private monitoring, as an expense or an investment? and why is the geographic expansion of private security partly the result of its link with the state?

Abstract: the aim of this study is to describe and compare the morphology and morphometry of leeches from intertidal fish. a total of 2,124 fish specimens that belonged to 15 species were collected from intertidal rocky pools from central chile. they were externally examined for leeches. twelve fish species harboured these parasites but only three of them had the sufficient number of individuals to perform morphometrical analyses. five morphotypes of leeches were classified according to their colour and size; three morphotypes (mt1, mt2 and mt3) were from scartichthys viridis, a morphotype (mt4) was from sicyases sanguineus, and another morphotype (mt5) was from aphos porosus. the five morphotypes were compared using six morphometrical measurements (length and width of the body, diameter of oral and posterior suckers, length of clitellum and position of clitellum from the anterior end). morphometrical comparisons were based on absolute and relative measurements. the results indicated that mt4 and mt5 differed from the other morphotypes, whereas mt1, 2 and 3 did not differ significantly among them. mt4 had body and suckers wider than the other four morphotypes, whereas mt5 was longer, thinner and with a longer clitellum than the other morphotypes. according to these results, each fish species, of the three analyzed, harboured a distinct morphospecies. these leeches belong to the piscicolidae family; although it was not possible to identify them at a genus level. this study also provides new records of leeches for nine intertidal fish species of chile.

Abstract: Entre el 20 y el 21 de julio se realizó en Panamá la X Conferencia Iberoamericana de Ministros de Juventud dedicada al tema Jóvenes y nuevo milenio: el reto de la ciudadanía. La Agenda buscaba evaluar las políticas públicas de juventud (1995-2000) en tres sectores prioritarios: educación, empleo y salud, y en desafíos particulares respecto a participación e institucionalidad pública e integración y cooperación entre los jóvenes. El autor del ensayo hace un análisis del tema en la subregión andina: Bolivia, Colombia, Ecuador, Perú y Venezuela.On July 20th and 21st, the Tenth Ibero-American Conference of Youth Ministers took place in Panama. The Conference focused on the topic: “Young People and the New Millennium: the Challenge of the Citizens.” The agenda included the evaluation of public youth policies (1995- 2000) in three priority sectors: education, employment and health, and particular challenges relating to participation and public institutionalism as well as integration and cooperation among young people. The author of the essay analises this topic in the Andean subregion: Bolivia, Colombia, Peru, and Venezuela.
Participación y conflicto en la educación básica
Germán Muoz G.
Nómadas , 2001,
Abstract: Entendida la participación como interacción ciudadana con el Estado y entre grupos o personas –asimétricos entre sí, con mentalidades e intereses diversos–que se encuentran en procesos de construcción de capital social y distribución de bienes públicos (por ejemplo, educación de calidad), ésta se encuentra fuertemente asociada al conflicto en el ámbito escolar. De hecho, la calidad educativa parece depender de relaciones cotidianas más frecuentes y menos jerarquizadas.Participation is understood as a citizen interaction with the state and between groups or persons, asymmetric between them, with diverse mentalities and interests - that find themselves in processes where social capital is constructed and public goods are distributed (as is the case in quality education). It finds itself strongly associated to conflict in the school context. In fact, education quality appears to depend on everyday relationships occurring more frequently and in a less hierarchical way.

Abstract: Este estudio describe y compara morfológica y métricamente a sanguijuelas de peces intermareales. Se recolectaron 2.124 peces de quince especies del intermareal rocoso de Chile central, los cuales fueron revisados externamente en búsqueda de sanguijuelas. Doce especies de peces albergaban a estos parásitos, pero sólo tres de ellas tenían números suficientes para compararlas morfométricamente. Se clasificaron cinco morfotipos de sanguijuelas según su color y tama o; tres morfotipos (MT1, MT2 y MT3) eran de Scartichthys viridis, un morfotipo (MT4) de Sicyases sanguineus y de morfotipo (MT5) en Aphos porosus. Estos cinco morfotipos fueron comparados en seis medidas corporales (largo y ancho del cuerpo, diámetro de las ventosas anterior y posterior, largo del clitelo y distancia desde éste a la ventosa anterior). Las comparaciones morfométricas, tanto de los análisis basados en medidas absolutas y relativas, indicaron que MT4 y 5 eran distintos a los otros morfotipos, mientras que MT1, 2 y 3 no se diferenciaban significativamente entre sí. MT4 tenía un cuerpo robusto, con cuerpo y ventosas más anchas que los otros cuatro morfotipos y el MT5 era más largo, delgado y un clitelo más largo que el resto de los morfotipos. Según estos antecedentes, cada especie de pez, de las tres analizadas, albergaba una morfoespecie distinta. Estas sanguijuelas corresponden a la familia Piscicolidae, aunque no fue posible identificarlos a nivel de género. Este estudio además aporta con nuevos registros de sanguijuelas para nueve especies de peces intermareales de Chile.

El Cotidiano , 2003,
Abstract: El arribo de la oposición en México supuso cambios importantes en la manera en que el Estado mexicano se relacionaría con el exterior. Sin duda, la política exterior de Vicente Fox ha presentado transformaciones importantes que se reflejan tanto en el dise o de sus estrategias internacionales como en la orientación programática hacia determinadas regiones. En el caso de la actuación hacia América Latina, la administración foxista ha desarrollado una política exterior que se caracteriza, por un lado, por el continuismo económico de la liberalización comercial con magros resultados, pero que también expresa, por otra parte, las nuevas líneas de acción en el ámbito político y de su nueva fundamentación democrática.

Abstract: case report: we describe the case of a 16 year-old woman, with inflammatory glaucoma secondary to juvenile rheumatic arthritis, successfully treated by ahmed glaucoma valve implant. two years later, a severe increase of intraocular pressure related to anterior tube migration occurred. the ahmed valve tube extender was successfully used to lengthen the tube. discussion: if the tube length is too short to reintroduce it into the eye, there are three surgical options: to use a tube extender, to insert the tube via the pars plana or to insert a new drainage implant. a piece of an angiocatheter or a silastic tube have been used for lengthening the tube of the valve implant; however the ahmed valve tube extender design makes surgery easier and allows keeping the valve in the original place, minimizing the risk of postoperative migration.
