BACKGROUND: Extrahepatic Portal vein aneurysm (EPVA) is a rare finding that may be associated with different complications, e.g. thrombosis, rupture, portal hypertension and compression of adjacent structures. It is being diagnosed more frequently with the advent of modern cross-sectional imaging. Our review of the English literature disclosed 13 cases of thrombosed EPVA. CASE PRESENTATION: A 50-years-old woman presented with acute abdominal pain but no other symptom. She had no relevant medical history. Palpation of the right upper quadrant showed tenderness. Laboratory tests were unremarkable. A computed tomography showed portal vein aneurysm measuring 88 × 65 mm with thrombosis extending to the superior mesenteric and splenic vein. The patient was treated conservatively with anticoagulation therapy. She was released after two weeks and followed on an outpatient basis. At two months, she reported decreased abdominal pain and her physical examination was normal. A computed tomography was performed showing a decreased thrombosis size and extent, measuring 80 × 55 mm. CONCLUSIONS: Although rare, surgeons should be made aware of this entity. Complications are various. Conservative therapy should be chosen in first intent in most cases. We reported the case of the second largest thrombosed extra-hepatic PVA described in the literature, treated by anticoagulation therapy with a good clinical and radiological response.

Els objectius de l'aplicació són: facilitar la feina a l'usuari que interactuï amb Microsoft Dynamics Ax, de manera que pugui navegar pel nostre portal sense cap complicació, garantir que l'usuari que està consultant la informació en un moment determinat, només pugui visualitzar informació referent al seu "rol", és a dir, que no es presenti la mateixa informació des del punt de vista del client que des del punt de vista d'un usuari intern, com per exemple podria ser un empleat, mostrar la informació de manera clara i concisa i realitzar gestions empresarials, depenent del perfil d'usuari, sense cap mena de complicació, com per exemple, poder realitzar una compra o poder realitzar qualsevol consulta.

S'ha dissenyat i implementat un portal web que a més de donar informació referent a l'establiment també oferirà serveis. Addicionalment a la consulta de tots els productes que ofereix l'establiment mitjançant la botiga virtual els clients podran realitzar les seves compres. A més s'ha dissenyat una interfície fàcil de gestionar per part dels usuaris administradors que en aquest cas seran els mateixos propietaris de l'establiment.

El portal web és un excel·lent mitjà per poder informar sobre el funcionament d'una empresa. Aquest treball que he realitzat està encarat a una cooperativa agrícola, ja que jo tinc un gran interès en el sector agrari degut a la zona en que visc que és el Pla d'Urgell. El portal web que he realitzat està pensat perquè totes les persones interessades en tenir informació sobre la cooperativa hi puguin accedir . Aquest té accessos diferents. Un accés serà el d'una persona visitant que entra en el portal per obtenir informació, l'altre serà pels socis de la cooperativa, que podran consultar la quantitat de fruita que entren, i l'últim tipus d'accés serà el de l'administrador del portal, que aquest serà l'únic que podrà tenir control absolut del portal, com per exemple, donar d'alta a un soci, entre altres.

In the era of antiretroviral therapies, the outcome of patients with chronic HIV infection has considerably changed and their prolonged survival allows the development of chronic liver diseases as a major cause of mortality. Although viral hepatitis, alcoholic and non alcoholic steatohepatitis account forthe majority of chronic liver damage in these patients, there is a growing number of cases with unexplained liver disease, many of which are associated with clinical manifestations of portal hypertension. Inthissituation, nodularregenerative hyperplasia is a frequent finding, characterized at histology by the presence of a nodular architecture in the absence of significant fibrosis, resulting from progressive obliteration of small portal veins. This article describes the clinical presentation, diagnostic aspects, pathogenic mechanisms, as well as the management of this emergent non cirrhotic liver disease in HIV-infected patients.

El proyecto puede dividirse en dos grandes partes, diseño de un portal deportivo y análisis de una herramienta Open Source para el desarrollo de portales web. El apartado de diseño cuenta con un club de atletismo que proporciona unos requerimientos y necesidades de cara a tener un problema real y no basado en especulaciones. Se ha diseñado tanto la base de datos como la estructura del portal y se tienen en cuenta las necesidades del cliente. La parte de análisis de una herramienta Open Source desglosa los módulos de esta, viendo que necesidades cubre cada uno y que pueden hacer, que tecnologías usan y que soluciones pueden dar al problema planteado.

Background: There is growing evidence that traffic-related air pollution reduces birth weight. Improving exposure assessment is a key issue to advance in this research area.Objective: We investigated the effect of prenatal exposure to traffic-related air pollution via geographic information system (GIS) models on birth weight in 570 newborns from the INMA (Environment and Childhood) Sabadell cohort.Methods: We estimated pregnancy and trimester-specific exposures to nitrogen dioxide and aromatic hydrocarbons [benzene, toluene, ethylbenzene, m/p-xylene, and o-xylene (BTEX)] by using temporally adjusted land-use regression (LUR) models. We built models for NO2 and BTEX using four and three 1-week measurement campaigns, respectively, at 57 locations. We assessed the relationship between prenatal air pollution exposure and birth weight with linear regression models. We performed sensitivity analyses considering time spent at home and time spent in nonresidential outdoor environments during pregnancy.Results: In the overall cohort, neither NO2 nor BTEX exposure was significantly associated with birth weight in any of the exposure periods. When considering only women who spent < 2 hr/day in nonresidential outdoor environments, the estimated reductions in birth weight associated with an interquartile range increase in BTEX exposure levels were 77 g [95% confidence interval (CI), 7–146 g] and 102 g (95% CI, 28–176 g) for exposures during the whole pregnancy and the second trimester, respectively. The effects of NO2 exposure were less clear in this subset.Conclusions: The association of BTEX with reduced birth weight underscores the negative role of vehicle exhaust pollutants in reproductive health. Time–activity patterns during pregnancy complement GIS-based models in exposure assessment.

Winter maintenance, particularly snow removal and the stress of snow removal materials on public structures, is an enormous budgetary burden on municipalities and nongovernmental maintenance organizations in cold climates. Lately, geospatial technologies such as remote sensing, geographic information systems (GIS), and decision support tools are roviding a valuable tool for planning snow removal operations. A few researchers recently used geospatial technologies to develop winter maintenance tools. However, most of these winter maintenance tools, while having the potential to address some of these information needs, are not typically placed in the hands of planners and other interested stakeholders. Most tools are not constructed with a nontechnical user in mind and lack an easyto-use, easily understood interface. A major goal of this project was to implement a web-based Winter Maintenance Decision Support System (WMDSS) that enhances the capacity of stakeholders (city/county planners, resource managers, transportation personnel, citizens, and policy makers) to evaluate different procedures for managing snow removal assets optimally. This was accomplished by integrating geospatial analytical techniques (GIS and remote sensing), the existing snow removal asset management system, and webbased spatial decision support systems. The web-based system was implemented using the ESRI ArcIMS ActiveX Connector and related web technologies, such as Active Server Pages, JavaScript, HTML, and XML. The expert knowledge on snow removal procedures is gathered and integrated into the system in the form of encoded business rules using Visual Rule Studio. The system developed not only manages the resources but also provides expert advice to assist complex decision making, such as routing, optimal resource allocation, and monitoring live weather information. This system was developed in collaboration with Black Hawk County, IA, the city of Columbia, MO, and the Iowa Department of transportation. This product was also demonstrated for these agencies to improve the usability and applicability of the system.
