INTRODUCTION: Resotrative proctolectomy (RPC) with Ileal-pouch anal anastomosis (IPAA) is the procedure of choice for ulcerative colitis. Unfortunately, up to 10% of pouches will fail, requiring either reconstruction or excision. While several series have reported on the aetiology of pouch failure, no study to date has focused on the postoperative complications associated with pouch excision. METHODS: Patients who had excision of ileoanal reservoir with ileostomy (CPT code 45136) were included...

The chemical composition of atmospheric particulate matter (PM) has been studied at the cities of Cordoba and Granada (South of Spain) between 2007 and 2013, considering urban background, traffic and industrial monitoring stations. The results of Principal Component Analysis (PCA) indicated that geochemical anomalies observed in the ambient air of Cordoba (mainly Cu, Zn, Pb and Cd) are closely related to the geochemical profile obtained from fugitive metallurgy emissions of brass industries. These findings have been confirmed performing an Sb speciation analysis of PM10 samples, which allowed to distinguish between Sb(III) and Sb(V)...

Background and Aims: Inflammatory bowel disease (IBD) patients are still under-diagnosed or diagnosed with serious delay. We examined whether diagnostic delay (DD) in IBD has changed over the last 60 years, and explored the risk factors of longer DD. Methods: 3392 IBD patients recorded in the registry of four IBD Italian centres were divided according to the year of diagnosis into a historical cohort (HC: 1955-1984) and modern cohort (MC: 1985-2014). DD, i.e. time lapse between onset of symptoms indicative of IBD and definitive diagnosis, was divided into four sub-periods (0-6, 7-12, 13-24, >24 months) which were correlated with age and disease location/behaviour at diagnosis...

Vibeke Andersen, Axel Kornerup Hansen, Berit Lilienthal Heitmann
We wanted to investigate the current knowledge on the impact of diet on anti-TNF response in inflammatory bowel diseases (IBD), to identify dietary factors that warrant further investigations in relation to anti-TNF treatment response, and, finally, to discuss potential strategies for such investigations. PubMed was searched using specified search terms. One small prospective study on diet and anti-TNF treatment in 56 patients with CD found similar remission rates after 56 weeks among 32 patients with good compliance that received concomitant enteral nutrition and 24 with poor compliance that had no dietary restrictions (78% versus 67%, p = 0...
