Correlación bioestratigráfica entre las sucesiones miocénicas marinas de Sant Pau d'Ordal y Sant Llorenç d'Hortons (Depresión del Vallès-Penedès, Barcelona)

The paleoenvironmental reconstruction of the St. Pau d'Ordal and La Pedrera de St. Lloren9 d'Hortons sections (Penedes area) is realized on the basis of molluscan fossils and sedimentological criteria. The lateral equivalente of both localities - which are dated to a Langhian-Lower Serravalian age - is deduced. The presence of the pteropod Vaginella austriaca, IUTTL - which is cited for the first time in some localities of the Penedes area - allows us affirm that during this epoch a good communication between the Penedes gulf and the open sea existed

Perioperative management and early complications after intestinal resection with ileocolonic anastomosis in Crohn’s disease: analysis from the PRACTICROHN study

This study is aimed at describing the prevalence of and risk factors associated with early post-operative complications after Crohn’s disease-related intestinal resection. Methods: This was a retrospective analysis of data from the PRACTICROHN cohort. Adult Crohn’s disease patients who underwent ileocolonic resection with ileocolonic anastomosis between January 2007 and December 2010 were included. The complications evaluated included death, ileus, anastomotic leak, abscess, wound infection, catheter-related infection, digestive bleeding and other extra-abdominal infections that occurred in the 30 days after surgery.Results: A total of 364 patients (median age at surgery 38 years and 50% men) were included. Indication for surgery was: stricturing disease (46.4%), penetrating disease (31.3%), penetrating and stricturing disease (14.0%) or resistance to medical treatment (5.8%). Early complications were recorded in 100 (27.5%) patients, with wound infection, intra-abdominal abscess and anastomotic leakage being the most frequent complications. Median hospitalization duration was 16 days for patients with complications vs. 9 days without complications (P<0.001). Complications were more common among patients with penetrating disease (36/114, 31.6%) and those refractory to treatment (9/21, 42.9%) compared with stricturing disease (45/169, 26.6%) or stricturingþpenetrating disease (6/51, 11.8%) (P¼0.040). The rate of complications was higher among patients with diagnosis made at the time of surgery (15/31, 48.4%) compared with the rest (85/331, 25.7%) (P¼0.013). Medication received at the time of surgery did not affect the rate of complications. Conclusions: Almost a quarter of patients developed early complications after intestinal resection. Penetrating disease and urgent surgery were associated with an increased risk of complicationsThis study was supported by Merck Sharp and Dohme, Spai

Influència del tabac en la resposta a azatioprina en malaltia inflamatòria intestinal corticodepenent

Disposem d'evidència sobre la influència negativa del tabac en la malaltia de Crohn i el seu efecte positiu en la Colitis ulcerosa. Per altra banda, no s'ha avaluat una potencial interacció entre el tabaquisme i la resposta a determinats fàrmacs. En el present treball hem avaluat l'eficàcia de les tiopurines en la malaltia inflamatòria intestinal corticodepenent, en relació a l'existència d'hàbit tabàquic a l'inici del tractament i la seva influència en el seguiment dels pacients amb resposta inicial al fàrmac, valorant la necessitat de teràpies de rescat o de tractament quirúrgic durant la seva evolució segons l'hàbit tabàquic

Evolució clínica després de la retirada d'infliximab en pacients amb MII en remissió clínica i endoscòpica sota tractament combinat amb tiopurines

Objectius: Avaluar la retirada d'infliximab en pacients amb MII, en remissió mantinguda i curació mucosa sota tractament combinat. Mètodes: Pacients amb MC luminal o CU sota tractament combinat (infliximab i azatioprina) durant mínim un any, als quals se'ls retira l'infliximab per remissió clínica, biològica i endoscòpica. Resultats: S'inclogueren 26 pacients. Un 73% es van mantenir en remissió. La recidiva no s'associà al fracàs previ d'immunomoduladors. A les recidives se'ls va reiniciar infliximab amb bona resposta. Cap factor va associar-se a la recidiva. Conclusions: La retirada de l'infliximab en aquests pacients, s'acompanya d'una baixa probabilitat de recidiva a mig termini

Long-term outcome of patients wih distal ulcerative colitis and inflammation of the appendiceal orifice

Background & Aims: Skip inflammation of the appendiceal orifice has been described in distal UC (UC-IAO) but long-term clinical outcomes are poorly established. Our aim was to evaluate the long-term clinical outcomes of UC-IAO as compared to classic distal UC. Methods: Patients with UC-IAO were identified from the local IBD database. Disease outcome and therapeutic requirements during follow-up were accurately collected, and compared with a control group of patients with distal UC without periappendiceal involvement matched by disease extent (proctitis/distal), smoking habit, and date and age at diagnosis. Results: Fourteen UC patients were found to have UC-IAO, most of them with initial extent of UC limited to the rectum. All patients were initially managed with mesalazine administered orally (28.5%), topically (28.5%), or in combination (43%). After a median follow-up of 78 months (interquartile range - IQR 45-123) most UC-IAO patients were successfully managed with oral and/or topical aminosalycilates. Only one of them developed proximal disease progression. As compared to controls, no differences in clinical outcomes or therapeutic requirements were found. Conclusions: Patients with UC-IAO tend to present a mild course, with a low probability to develop proximal progression of disease extent or to require immunosuppressive therapy or colectomy.CIBERehd of Fondo de Investigación Sanitaria of the Instituto de Salud Carlos III, from the Spanish Ministry of HealthMedicin

Colitis ulcerosa con afectación periapendicular. Estudio de casos y controles

La colitis ulcerosa (CU) es caracteritza per una afectació contínua de la mucosa rectal en sentit proximal cap a altres zones del còlon. Hi ha formes de CU amb afectació distal i periapendicular (CU-PA). Objectius: avaluar la prevalença de la CU-PA, i comparar les seves característiques clíniques, terapèutiques i evolutives. Mètodes: 14 pacients amb CU-PA van ser comparats en termes d'evolució clínica amb 25 pacients amb CU distal sense afectació periapendicular. Resultats: Es va trobar una major freqüència de CU-PA en homes (p = 0,047), sense diferències en la resta de les variables comparades entre els dos grups de pacients.La colitis ulcerosa (CU) se caracteriza por una afectación continua de la mucosa rectal en sentido proximal hacia otras zonas del colon.

Management and outcomes of patients with Crohn’s disease with first vs multiple surgeries: results from the PRACTICROHN study

Background: Surgery in Crohn’s disease (CD) may be associated with poor prognosis and clinical and surgical recurrence. The aim of this study was to describe and compare the post-operative management and outcomes of patients with CD who underwent first vs recurrent surgeries. Methods: Observational study that included adult CD patients from 26 Spanish hospitals who underwent ileocolonic resection with ileocolonic anastomosis between January 2007 and December 2010. Data were retrospectively collected from the medical records. Results: Data from 314 patients were analysed, of whom 262 (83%) underwent first surgery and 52 (17%) referred to previous CD surgeries. Baseline characteristics were similar between the two groups except for a higher rate of stricturing behavior at diagnosis among re-operated patients (P¼0.03). After surgery, a higher proportion of re-operated patients received prophylactic treatment with immunomodulators compared with patients with first surgery (P¼0.04). In re-operated patients, time to clinical recurrence was not associated with the fact of receiving or not prophylaxis, whereas, in patients with first surgery, recurrence-free survival was greater when prophylaxis was received (P¼0.03). Conclusions: After surgery, a higher proportion of patients with previous surgeries received prophylactic treatment with immunomodulators compared with patients with first surgery. Although prophylactic treatment was beneficial for preventing clinical recurrence in patients operated on for the first time, it did not significantly reduce the risk of further recurrence in patients with previous surgeries. This suggests that effective prophylactic therapies are still needed in this subset of patientsThis study was funded by Merck Sharp & Dohme of Spain, a subsidiary of Merck & Co., Inc., Kenilworth, New Jersey, US

Post-Marketing Health Technology Monitoring. The Analysis of an Experience from a Clinical Perspective

Introduction: A system for monitoring the use of aphaeresis in the treatment of ulcerative colitis (UC), named system for monitoring aphaeresis in ulcerative colitis (SiMAC), was designed in 2006 in the Basque Country. In the present study, the opinion of the clinicians who participated in SiMAC was evaluated, in order to identify the barriers and gather suggestions that could improve implementation of this kind of system. Methods: A mixed questionnaire was designed, in order to gather clinicians’ assessments of the SiMAC monitoring system. Results: The response rate was 73.9% (17/23). The data from 40.96% (159/388) of patients with UC treated with aphaeresis was recorded. The main reasons for not including the data from all treated patients were a lack of required data or not meeting the study inclusion criteria. Positive aspects of the SiMAC were identified, as the simplicity of data collection and its systematic, multi-center approach. The negative aspects mentioned were the use of a local computer application and the lack of time for health professionals to enter data. Discussion: The use of monitoring systems helps to formalize the introduction of technologies of little-known effectiveness; involve clinicians and medical societies in coming to agreement and obtaining information about the safety, effectiveness or efficiency of new technologies; and provide relevant information to healthcare administrations for making decisions about the introduction of new technologies into healthcare practice. In order for a monitoring system to work, the process must be straightforward. A minimum set of key variables that are easy to collect must be selected, and an effort made to involve a range of stakeholders, especially institutions and scientific societies, to support the work group
