: The aim of this exploratory trial was to establish if the probiotic Bifidobacterium natren life start (NLS) strain strain may affect the clinical course and pathophysiological features of patients with untreated celiac disease (CD). Positive findings would be helpful in directing future studies.

It is becoming increasingly recognized that purely clinical endpoints may not be sufficient in the treatment of patients with inflammatory bowel disease. As such, mucosal disease assessment has become a prominent component of the majority of recent clinical trials in Crohn’s disease and ulcerative colitis. There is mounting evidence that the attainment of mucosal healing leads to improved clinical outcomes in both Crohn’s disease and ulcerative colitis. However, the use of mucosal healing as a therapeutic endpoint in inflammatory bowel disease is in its early stages, as a number of issues limit its application to routine clinical practice.

GOALS:: To evaluate sources of upper gastrointestinal bleeding (UGIB) at an urban US hospital and compare them to sources at the same center 20 years ago, and to assess clinical outcomes related to source of UGIB. BACKGROUND:: Recent studies suggest changes in causes and outcomes of UGIB. STUDY:: Consecutive patients with hematemesis, melena, and/or hematochezia undergoing upper endoscopy with an identified source at LA County+USC Medical Center from January 2005 to June 2011 were identified retrospectively. RESULTS:: Mean age of the 1929 patients was 52 years; 75% were male. A total of 1073 (55%) presented with hematemesis, 809 (42%) with melena alone, and 47 (2%) with hematochezia alone. The most common causes were ulcers in 654 patients (34%), varices in 633 (33%), and erosive esophagitis in 156 (8%), compared with 43%, 33%, and 2% in 1991. During hospitalization, 207 (10.7%) patients required repeat endoscopy for UGIB (10.6% for both ulcers and varices) and 129 (6.7%) died (5.2% for ulcers; 9.2% for varices). On multivariate analysis, hematemesis (OR=1.38; 95% CI, 1.04-1.88) and having insurance (OR=1.44; 95% CI, 1.07-1.94) were associated with repeat endoscopy for UGIB. Varices (OR=1.53; 95% CI, 1.05-2.22) and having insurance (OR=4.53; 95% CI, 2.84-7.24) were associated with mortality. CONCLUSION:: Peptic ulcers decreased modestly over 2 decades, whereas varices continue as a common cause of UGIB at an urban hospital serving lower socioeconomic patients. Inpatient mortality, but not rebleeding requiring endoscopy, was higher with variceal than nonvariceal UGIB, indicating patients with variceal UGIB remain at risk of death from decompensation of underlying illness even after successful control of bleeding.

There is increasing recognition of Crohn’s disease (CD) in non-white populations. However, reports of racial disparities in the phenotype of CD are still inconsistent. AIM:: The aim of this study was to test the hypothesis that African American (AA) patients have higher incidence of severe fistulizing perianal Crohn’s disease (FPD) compared with white patients.

Procedure-related complications of percutaneous transhepatic biliary drainage (PTBD) have been well documented in the literature. However, relatively restricted data are available concerning drainage-related complication rates in long-term PTBD therapy. The present retrospective study evaluated the extent and the nature of drainage complications during PTBD therapy and associated risk factors for these complications.

Laparoscopic Roux-en-Y gastric bypass (RYGB) is widely applied in the treatment of morbid obesity. Health personnel meeting these patients should thus be familiar with the potential clinical consequences of the modified anatomy induced by the surgery. After a RYGB, the stomach is left in situ after the closure of the upper part of the organ. This blind-ended gastric remnant may cause complications and surgical emergencies, but also opportunities for diagnostic and therapeutic intervention. The present review focuses on complications related to the gastric remnant including bleeding and acute dilatation in the early postoperative period and later adverse events such as gastroduodenal peptic disease, tumors, gastrogastric fistulas, and late dilatation. Opportunities offered by the remnant, including minimal invasive or open access for enteral nutrition, and therapeutic and diagnostic access to the bile ducts, the duodenum, and the gastric remnant, which is challenged by the modified anatomy, are discussed. Reversal of the gastric bypass and gastrointestinal reconstruction after esophageal resection have been commented on. The review aims to improve the awareness of issues related to the gastric remnant for physicians involved in the treatment and the follow-up of patients after a RYGB.
