Eosinophilic esophagitis (EoE) is the most common cause of esophageal food impaction (EFI). Approaches to management of EFI due to EoE have not been well characterized. We conducted a web-based survey to understand approaches to management of EFI due to EoE among endoscopists. Questions focused on management of patients from presentation to post-endoscopy follow-up. The survey was administered to a list of eligible candidates provided by societies of gastroenterology. A total of 308 endoscopists completed the questionnaire. The majority (83%) practiced in Europe and treated adults (78%). Most agreed patients should be advised to seek emergency care (66%) within 1 to 2 hours (41% agreement). There was agreement that medications to induce vomiting should be avoided (84%) and that blood tests or imaging studies were usually not required before endoscopy. By contrast, there was more variability in the type of sedation recommended and the need for endotracheal intubation, especially when comparing more experienced with less experienced EoE-endoscopists. Overall, fewer than half (43%) respondents recommended obtaining esophageal biopsies during the initial endoscopy. However, there were significant differences in the proportion who recommended biopsies based on level of EoE-experience (25, 52, 77%, P  < 0.001; less vs. moderate vs. very experienced) and comparing pediatric and adult endoscopists (32, vs. 79%, P  < 0.001; adult vs. pediatric). There exists heterogeneity among endoscopists in recommendations to manage EFI in patients with EoE. These findings support development of clinical guidelines and new studies to clarify the rationale for best practices. Key summary: Established knowledge —The optimal management of patients with esophageal food impaction due to eosinophilic esophagitis from presentation at the emergency department to postendoscopy care is unclear. New findings —Considerable recommendation variation exists in the management of EFI in patients with EoE. Our findings provide a rationale for the creation of consensus practice guidelines and further study into best practices. [ABSTRACT FROM AUTHOR]

Background: Molecular Adsorbents Recirculating System (MARS)-mini has recently been approved and applied in children with hepatic failure. However, its indication, efficacy and capability to induce liver regeneration remain unclear. The aim of our pilot study in children was to analyse the impact of MARS on markers of detoxification and regeneration.Methods: In children with fulminant Wilson's disease and bridged with MARSmini for liver transplantation, we analyzed toxic metabolites (bile acids, bilirubin, lactate, ammonia, tryptophan and copper), regulators of the inflammatory cascade [nitrate, tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), methionine, cystine and hyaluronic acid] and hepatic growth factors [hepatocyte growth factor (HGF), epidermal growth factor (EGF), transforming growth factor-beta1 (TGF-beta1), cortisol, corticosteroid-binding globulin (CBG), insulin-like growth factor-1 (IGF-1), angiogenin, vascular endothelial growth factor (VEGF), IL-6 and TNF-alpha] from blood, albumin circuit and haemodialysate from four applications.Results: In all four applications, transfer of toxic metabolites (6/6) and inflammatory mediators (6/6), but also of hepatic growth factors (9/10), into the albumin circuit of MARS was consistently detected. Corresponding blood levels were decreased for 3/6 metabolites, 3/6 inflammatory mediators and 1/10 growth factors and increased for 1/10 growth factors. Bridging for liver transplantation was successful with MARS.Conclusions: In our prospective study, substantial extraction of albumin-bound and water-soluble candidate substances was detected with variable effect on respective blood levels. Notably, essential factors inducing liver regeneration were simultaneously removed. These data provide a basis for evaluation of liver restoration and efficacy of liver support in children with liver failure to devise a collaborative, multicentre trial. [ABSTRACT FROM AUTHOR]
