The additive value of CA19.9 monitoring in a pancreatic cyst surveillance program.

Background: Surveillance of pancreatic cysts focuses on the detection of (mostly morphologic) features warranting surgery. European guidelines consider elevated CA19.9 as a relative indication for surgery.

Pancreatic cyst surveillance imposes low psychological burden.

Background/objectives: For the currently recommended pancreatic cyst surveillance to be feasible, participant adherence is a prerequisite. Our objective was to evaluate the psychological burden of pancreatic cyst surveillance from a participant's perspective.

Methods: The present participant survey is part of an international cohort study (PACYFIC study, www.

Short article: Willingness to undergo colonoscopy with virtual reality instead of procedural sedation and analgesia.

Objective: This study explored the willingness of patients to start colonoscopy with virtual reality (VR) instead of procedural sedation and analgesia (PSA), as well as their motives and characteristics. There is a growing interest in colonoscopy without PSA. Offering VR as a distraction technique instead of PSA may increase the percentage of colonoscopies without PSA.

A jaundiced bodybuilder Cholestatic hepatitis as side effect of injectable anabolic-androgenic steroids.

The use of anabolic steroids is prevalent in recreational athletes. This case report describes a young amateur bodybuilder who was referred to our outpatient clinic with jaundice and loss of appetite due to cholestatic hepatitis. Additional tests including a liver biopsy made it likely that the hepatitis was caused by the injectable anabolic steroid trenbolone enanthate.

Higher quality of life after metal stent placement compared with plastic stent placement for malignant extrahepatic bile duct obstruction: a randomized controlled trial.

Objective: For palliation of extrahepatic bile duct obstruction, self-expandable metal stents (SEMS) are superior to plastic stents in terms of stent patency and occurrence of stent dysfunction. We assessed health-related quality of life (HRQoL) after stent placement to investigate whether this also results in a difference in HRQoL between patients treated with a plastic stent or SEMS.

Patients And Methods: This randomized multicenter trial included 219 patients who were randomized to receive plastic stent (n=73) or SEMS [uncovered (n=75) and covered (n=71); n=146] placement.

Same-admission versus interval cholecystectomy for mild gallstone pancreatitis (PONCHO): a multicentre randomised controlled trial.

Background: In patients with mild gallstone pancreatitis, cholecystectomy during the same hospital admission might reduce the risk of recurrent gallstone-related complications, compared with the more commonly used strategy of interval cholecystectomy. However, evidence to support same-admission cholecystectomy is poor, and concerns exist about an increased risk of cholecystectomy-related complications with this approach. In this study, we aimed to compare same-admission and interval cholecystectomy, with the hypothesis that same-admission cholecystectomy would reduce the risk of recurrent gallstone-related complications without increasing the difficulty of surgery.

Cost Efficacy of Metal Stents for Palliation of Extrahepatic Bile Duct Obstruction in a Randomized Controlled Trial.

Background & Aims: Endoscopic stents are placed for palliation of extrahepatic bile duct obstruction. Although self-expandable metal stents (SEMS) remain patent longer than plastic stents, they are more expensive. We aimed to evaluate which type of stent (plastic, uncovered SEMS [uSEMS], or partially covered SEMS [pcSEMS]) is the most effective and we assessed costs.

Ulcerative colitis patients with an inflammatory response upon mesalazine cannot be desensitized: a randomized study.

Background And Aims: Mesalazine is a key drug in the treatment of ulcerative colitis (UC). Intolerance to mesalazine has been described, including fever and gastrointestinal symptoms. Several case reports reported successful desensitization of patients with mesalazine intolerance.

[The low FODMAP diet as a therapy for irritable bowel syndrome].

Irritable bowel syndrome (IBS) is a very common, sometimes disabling disorder for which there is a lack of effective treatments. Many patients report that the make-up of the diet has an effect on their symptoms. The western diet consists of many different molecules.

Production objectives and trait preferences of village poultry producers of Ethiopia: implications for designing breeding schemes utilizing indigenous chicken genetic resources.

To generate information essential for the implementation of breeding schemes suitable for village poultry producers in Ethiopia, a survey was conducted aimed at defining the socioeconomic characteristics of the production environments in different geographic regions, understanding the important functions of chickens, identifying farmers' choice of chicken breeds and the underlying factors that determine the choice of genetic stock used. The survey included both questionnaire survey and a participatory group discussion. A total of 225 households (45 households from each of five Woredas) were interviewed.

Acute hepatitis B in a healthcare worker: a case report of genuine vaccination failure.

Background: Individuals who reach the antibody threshold level of 10IU/l against the surface protein of the hepatitis B virus (HBV) after completion of a series of hepatitis B vaccination are considered to be long-term protected against a clinically manifest HBV infection.

Case Report: Here we describe an acute hepatitis B infection in a patient who received five hepatitis B vaccinations. Although his initial response to vaccination was moderate, he finally reached an excellent hepatitis B surface antibody level (anti-HBs) titres of more than 1000 IU/l in response to a booster vaccination with a recombinant DNA vaccine.

Once daily MMX mesalazine for the treatment of mild-to-moderate ulcerative colitis: a phase II, dose-ranging study.

Background: SPD476 (MMX mesalazine), is a novel, once daily, high-strength mesalazine formulation (1.2 g/tablet) that utilizes Multi Matrix System (MMX) technology to delay and extend delivery of the active drug throughout the colon.

Aim: To assess the safety and efficacy of MMX mesalazine in patients with mild-to-moderately active ulcerative colitis, in a pilot, phase II, randomized, multicentre, double-blind, parallel-group, dose-ranging study (SPD476-202).

Bacterial population analysis of human colon and terminal ileum biopsies with 16S rRNA-based fluorescent probes: commensal bacteria live in suspension and have no direct contact with epithelial cells.

Background: The commensal intestinal microflora has important metabolic and perhaps also immune modulatory functions. Evidence has accumulated that the microflora plays a role in the pathogenesis of inflammatory bowel disease. Therefore, there is a growing interest in the intestinal microflora and its interaction with the host.

Cyst fluid analysis in the differential diagnosis of pancreatic cystic lesions: a pooled analysis.

Background: Pancreatic cystic tumors commonly include serous cystadenoma (SCA), mucinous cystadenoma (MCA), and mucinous cystadenocarcinoma (MCAC). A differential diagnosis with pseudocysts (PC) can be difficult. Radiologic criteria are not reliable.

Relative contributions of NOS isoforms during experimental colitis: endothelial-derived NOS maintains mucosal integrity.

The role of nitric oxide (NO) in inflammatory bowel diseases has traditionally focused on the inducible form of NO synthase (iNOS). However, the constitutive endothelial (eNOS) and neuronal (nNOS) isoforms may also impact on colitis, either by contributing to the inflammation or by regulating mucosal integrity in response to noxious stimuli. To date, studies examining the roles of the NOS isoforms in experimental colitis have been conflicting, and the mechanisms by which these enzymes exert their effects remain unclear.

Immunoglobulin coating of faecal bacteria in inflammatory bowel disease.

Objective: An inappropriate mucosal immune response to the commensal bacterial flora may play a role in the pathogenesis of inflammatory bowel disease (IBD). In this study we determined the percentage of immunoglobulin-coated bacteria in the stools of patients and controls.

Methods: Faecal samples were obtained from 18 patients with IBD (one sample during exacerbation and one shortly after remission was achieved), 15 healthy volunteers, eight infectious colitis patients, and 13 IBD patients in long-term remission.

High-grade dysplasia in sporadic fundic gland polyps: a case report and review of the literature.

We present a case of fundic gland polyps (FGPs) containing high-grade dysplasia in a 68-year-old man. High-grade dysplasia, and even gastric adenocarcinoma, associated with FGPs have been described in patients with familial adenomatous polyposis (FAP) and attenuated familial adenomatous polyposis (AFAP) but never in non-FAP patients. Two colonoscopies in the past six years virtually rule out FAP and AFAP in our patient.

[Acute disorders of intestinal perfusion; a nonrigid abdomen may still be acute].

Three patients, a man aged 50 years and two women aged 46 and 45 years, with abdominal pains and an undistended abdomen, were found to have acute mesenteric ischaemia. The causes were: unknown, a thrombus in the descending aorta and severe atherosclerosis, respectively. In the male patient, only 30 cm of vital small intestine ultimately remained; in one woman embolectomy sufficed, in the other, resection of a limited portion of the jejunal tract.

In vivo IgA coating of anaerobic bacteria in human faeces.

The bacterial flora in the human colon, although extremely diverse, has a relatively stable composition and non-infectious anaerobic bacteria are dominant. The flora forms a pool of numerous different antigens separated from mucosal immunocompetent cells by just a single layer of epithelial cells. Despite this thin barrier, however, the colonic mucosa is physiologically only mildly inflamed.

Direct flow cytometry of anaerobic bacteria in human feces.

We describe a flow cytometry method for analysis of noncultured anaerobic bacteria present in human fecal suspensions. Nonbacterial fecal compounds, bacterial fragments, and large aggregates could be discriminated from bacteria by staining with propidium iodide (PI) and setting a discriminator on PI fluorescence and by exclusion of events with large forward scatter. Since anaerobic bacteria, which account for over 99.

A norfloxacin dose finding study for selective decontamination of the digestive tract in pigs.

Five pigs were treated orally with norfloxacin for 5 consecutive days in two well-separated periods. This was done to determine the lowest dose required to free the pigs of Enterobacteriaceae. In the first period of the study, the animals were treated with 400 mg per day while in the second treatment 800 mg norfloxacin was given.
