Our findings highlight the role of irrational cognition and coping mechanisms in patients with IBS. The results underline the importance of the evaluation of psychological aspects of IBS with the possibility of having more tailored treatments for these patients.

Patients with chronic viral hepatitis not receiving antiviral therapy have an impaired quality of life as estimated by the Short Form 36 health survey.

Abstract Background Contrast-enhanced harmonic endoscopic ultrasound (CH-EUS) can visualize necrotic areas and vessels inside lesions. CH-EUS findings combined with EUS-guided fine-needle aspiration (EUS-FNA) improves diagnosis in pancreatic solid masses. CH-EUS can also guide EUS-FNA (CH-EUS-FNA), potentially improving the diagnostic rate of EUS-FNA, but such superiority has not been proved in prospective studies. We aimed to assess whether CH-EUS-FNA is superior to standard EUS-FNA for specific diagnosis of solid pancreatic masses and what factors affect the diagnostic rate. Methods This randomized controlled study in one tertiary medical academic center included patients with suspected pancreatic solid masses on transabdominal ultrasound or computed tomography (CT) scan. Two passes with a 22-G standard FNA needle were done using EUS-FNA and CH-EUS-FNA in random order, and the visible core obtained was sent for histological analysis. Final diagnosis was based on EUS-FNA or surgical specimen results and on 12-month follow-up by imaging. Results 148 patients were evaluated. EUS-FNA and CH-EUS-FNA showed diagnostic sensitivities of 85.5 % and 87.6 %, respectively (not significantly different) and the combined sensitivity of the two passes was 93.8 %. The false-negative rate was not significantly different when hypoenhanced or hyperenhanced lesions were compared with the EUS-FNA results. No differences were seen for the results related to location, size, tumor stage, chronic pancreatitis features, or presence of biliary plastic stent. Conclusions The diagnostic rates for samples obtained using 22-G needles with standard EUS-FNA and CH-EUS-FNA were not statistically significantly different.

The authors describe a study investigating the relationship between posthypnotic amnesia (PHA) and directed forgetting (DF) and their impact on implicit and explicit memory. This study adopted a recent modification of the process dissociation procedure to accommodate the cross-contamination of memory test performance by implicit and explicit memorial factors. Forty high and 40 low hypnotically susceptible participants were compared in PHA, DF, and control conditions on estimates of voluntary conscious (VCM), involuntary conscious (ICM), and involuntary unconscious memory (IUM) performance. Both groups showed significant decrements in VCM and ICM following instructions for DF, whereas only high susceptibles showed this decrement in the PHA condition; neither DF nor PHA affected IUM. Moreover, there was no relationship between forgetting in PHA and DF. Although both PHA and DF seem to prevent the conscious (i.e., explicit) expression of memorial information while leaving implicit memory intact, the mechanisms underlying these phenomena may nevertheless be different.

Transabdominal SWE represents a surrogate but feasible method for differentiation cancer from the normal pancreatic tissue. In a clinical setting, data regarding the stiffness complementary to an ultrasound evaluation could guide high-risk patients for a close-up pancreatic monitoring.

Background and Aims: The nonpharmacological therapy in irritable bowel syndrome (IBS) is expanding rapidly. Practitioners and medical educators need to be aware of progress and changes in knowledge of this topic. The Romanian Society of Neurogastroenterology aimed to create guidelines based on best evidence on the use of nonpharmacological therapy in IBS. Methods: A group of experts was constituted. This was divided in eleven subgroups dedicated to eleven categories of nonpharmacological therapy. The subgroups searched the literature and formulated statements and recommendations. These were submitted to vote in order to obtain consensus. Results: The outcome of this activity is represented by the guidelines of the Romanian Society of Neurogastroenterology, presented in this paper. The recommendations are seen as complementary to the pharmacological therapy and are not intended to recommend avoiding pharmacological drugs. Conclusions: These guidelines were elaborated by a Delphi process and represent a useful tool for physicians managing patients with IBS.

Background and Aims: The fully-covered, lumen apposing metal stents are designed for one step placement, facilitating the direct endoscopic necrosectomy into the walled-off pancreatic necrosis. However, the prediction of the number of necrosectomy sessions in these patients is not known. This study evaluated the association between the proportion of solid necrotic material inside walled-off necrosis, as assessed during the endosonography placement of a lumen apposing metal stent, and the number of necrosectomies subsequently required. Methods: Patients from three tertiary medical centers with symptomatic walled off pancreatic necrosis (pain, infection, gastric/biliary obstruction) at more than 4 weeks after onset of acute pancreatitis were retrospectively analysed. Proportion of solid necrotic debris was estimated during endosonography procedure of lumen apposing metal stents placement. Necrosectomy was performed when obstruction or inflammation occurred subsequently. Lumen apposing metal stents were removed after clearance of necrotic content. Results: In 46 patients with successful lumen apposing metal stents placement, necrosectomy was performed in 39 patients (72.78%). Performance of 3 or more necrosectomies was significantly associated with more than 50% pancreatic necrosis (p=0.032), but not with walled-off pancreatic necrosis size or location. Necrotic infection during lumen apposing metal stents stenting was associated with hypoalbuminemia, but not with necrosectomy requirement. Clinical success after a median follow-up of 13.37 months was 87%. Conclusions: Walled-off pancreatic necrosis with more than 50% solid necrotic content were associated with more necrosectomy procedures, requiering longer endoscopy time, intravenous sedations, and higher costs.

BackgroundThe cavitating mesenteric lymph node syndrome (CMLNS) is a rare manifestation of celiac disease, with an estimated mortality rate of 50%. Specific infections and malignant lymphoma may complicate its clinical course and contribute to its poor prognosis. Diagnosing the underlying cause of CMLNS can be challenging. This is the first report on contrast enhanced ultrasound (CEUS) findings in enteropathy associated T-cell lymphoma (EATL) complicating CMLNS in a gluten-free compliant patient with persistent symptoms and poor outcome.Case presentationWe present the case of a 51-year old Caucasian male patient, diagnosed with celiac disease and CMLNS. Despite his compliance to the gluten-free diet the symptoms persisted and we eventually considered the possible development of malignancy. No mucosal changes suggestive of lymphoma were identified with capsule endoscopy. Low attenuation mesenteric lymphadenopathy, without enlarged small bowel segments were seen on computed tomography. CEUS revealed arterial rim enhancement around the necrotic mesenteric lymph nodes, without venous wash-out. No malignant cells were identified on laparoscopic mesenteric lymph nodes biopsies. The patient died due to fulminant liver failure 14 months later; the histopathological examination revealed CD3/CD30-positive atypical T-cell lymphocytes in the liver, mesenteric tissue, spleen, gastric wall, kidney, lung and bone marrow samples; no malignant cells were present in the small bowel samples.ConclusionsCEUS findings in EATL complicating CMLNS include arterial rim enhancement of the mesenteric tissue around the cavitating lymph nodes, without venous wash-out. This vascular pattern is not suggestive for neoangiogenesis, as arteriovenous shunts from malignant tissues are responsible for rapid venous wash-out of the contrast agent. CEUS failed to provide a diagnosis in this case.
