Background Rapid Urease Test (RUT) is a simple, cheap and relatively fast method for diagnosing Helicobacter pylori infection. It is therefore the preferred method used for patients undergoing gastroscopy. Most kits require 24 h to give results. The new Ultra-Rapid Urease Test (URUT) kit by Biohit® requires less than 1 h. Objective To determine URUT's diagnostic accuracy. Method Prospective, blind, multi-centre study involving dyspeptic patients. One corpus biopsy and three antral biopsies were obtained during gastroscopy for standard histological analysis, RUT and URUT. The URUT result was checked after 1 min, 5 min, 30 min and 60 min and the RUT was checked over the course of 24 h. Histology was used as the gold standard test. Results 144 patients were included, 68% female, with a mean age of 49 years old; 50% were H. pylori positive. RUT and URUT diagnoses were correct in 85.9% and 90% of the cases, respectively. The mean waiting time for a positive RUT result was 6 h. The sensitivity, specificity, and positive and negative predictive values for RUT were, respectively, 82%, 90%, 89% and 84%. The URUT's results were similar (85%, 94%, 94% and 87%). These figures improved when patients taking PPIs were excluded (RUT: 86%, 91%, 93% and 83%; URUT: 91%, 94%, 96% and 89%). No statistically significant differences were found when comparing RUT and URUT distributions of correct diagnoses (McNemar's Test, p = 0.3) but there was a tendency towards better results with the URUT. Conclusion The URUT is equivalent to (or slightly better than) the traditional RUT in diagnosing H. pylori infection, and provides results in less than an hour.

We report the case of a young man with chronic hepatitis B infection of probable perinatal acquisition who was diagnosed with hepatocellular carcinoma at a very early stage (BCLC 0) with a highly favorable prognosis. However, the tumor progressed rapidly and the patient died within months. Currently, there are few data that could help to identify cases likely to show rapid progression and which could prompt initiation of aggressive therapies that might prevent or control such progression.

Resumen La unidad de atencion continuada y hospital de dia permite el manejo ambulatorio de los pacientes con una enfermedad digestiva. Objetivo Disminuir los ingresos hospitalarios y el numero de pacientes con una enfermedad digestiva que acude a urgencias. Material y metodos Los pacientes se atienden segun dos niveles asistenciales: a) atencion continuada, en que se visitan de forma urgente los pacientes con una descompensacion aguda de su enfermedad digestiva, y b) atencion programada, en que se realizan procedimientos que por su complejidad requieren personal de enfermeria, sin ser necesario el ingreso hospitalario. Resultados En el periodo comprendido entre 1995 y 2005 se ha pasado de realizar 118 visitas en atencion continuada en 1995 a 784 en 2005. En atencion programada las paracentesis han aumentado de 237 en 1995 a 687 en 2006 y las infusiones de hierro intravenoso de 111 en 2004 a 519 en 2006. El numero de ingresos hospitalarios paso inicialmente de 605 en 1995 a 430 en 2000, para posteriormente aumentar. El numero de pacientes con una enfermedad digestiva que acudio a urgencias disminuyo un 75% estos anos. Conclusiones La unidad de atencion continuada y hospital de dia permite una disminucion inicial del numero de ingresos en el area de hospitalizacion convencional y en el porcentaje de pacientes con patologia digestiva que acuden a urgencias.

INTRODUCTION The aim of the abstracts presented at scientific meetings is their publication in a peer-review journal. In this study, we analysed the publication rates of the abstracts submitted to the 24th AEEH meeting (1999) and also to see if this was stable over time. MATERIAL AND METHODS We assessed the publication rates of the abstracts presented at the 24th AEEH meeting in journals included in MEDLINE. As a comparison tool, we did the same with the abstracts submitted to the 34th Annual Meeting of the European Association for the Study of the Liver (EASL). The same procedure was carried out on the three subsequent editions of AEEH meetings to evaluate the continuity in the long term. RESULTS Of the abstracts submitted at the 24th AEEH meeting, 52.8% (93/176) were published: 71.4% of those had been accepted for oral presentation, 54% as a poster and 41% were non-accepted abstracts. From the 34th EASL Annual Meeting, 27.1% (248/913) of the submitted abstracts were published (p < 0.001 compared to AEEH), 52.5% of those were accepted for oral communication, 33.1% accepted as a poster communication and 18.1% from non-accepted abstracts. Moreover, this high publication rate of the abstracts of AEEH meeting at 1999, was maintained during the following three years (47.55 and 54%, respectively). CONCLUSIONS a) The publication rate of abstracts presented at 24th AEEH meeting was excellent and superior in comparison to the EASL rate of the same year; b) almost three quarters of abstracts accepted for oral presentation and more than half of those accepted as a poster were finally published, and c) high publication rates seem to be maintained over time.

Introduccion: Menos de la mitad de los pacientes con hepatitis cronica C genotipo 3 (G3) con carga viral elevada y sin respuesta virologica rapida (RVR) alcanzan respuesta virologica sostenida (RVS) con peginterferon y ribavirina (RBV). Objetivos: Evaluar el impacto de altas dosis de RBV sobre la RVS en pacientes con G3 y carga viral elevada. Metodos: Noventa y siete pacientes recibieron asignacion aleatoria para tratamiento con peginterferon ?-2a + RBV800 mg/dia (A; n = 42) o peginterferon ?-2a + RBV 1600 mg/dia + epoetina ? 400 UI/kg/semana SC (B; n = 55). Los pacientes asignados al grupo B que alcanzaron RVR continuaron con RBV (800 mg/dia) durante 20 semanas mas (B1; n = 42) mientras que los que no alcanzaron RVR recibieron una dosis mas alta de RBV (1.600 mg/dia) + epoetina ? (B2; n = 13). Resultados: Se observo RVR en el 64,3% de los pacientes en A y 76,4% en B (p = 0,259). El analisis por intencion de tratar(ITT) mostro una tasa de RVS de 64,3% (A) y 61,8% (B), con una reduccion de -2,5% (-21,8�16.9%) (p = 0,835). La tasa de RVS fue 61,9% en brazo B1 y 61,5% en brazo B2. No se detectaron efectos adversos graves y la tasa de efectos adversos moderados fue < 5%. Conclusiones: Los pacientes G3 con carga viral elevada sin RVR no obtuvieron beneficio de dosis mas altas de RBV. Las dosis mas altas de ribavirina mas epoetina ? fueron seguras y bien toleradas.
