A Prospective, Multicenter Study of the AIMS65 Score Compared With the Glasgow-Blatchford Score in Predicting Upper Gastrointestinal Hemorrhage Outcomes.

Background: The AIMS65 score and the Glasgow-Blatchford risk score (GBRS) are validated preendoscopic risk scores for upper gastrointestinal hemorrhage (UGIH).

Goals: To compare the 2 scores' performance in predicting important outcomes in UGIH.

Study: A prospective cohort study in 2 tertiary referral centers and 1 community teaching hospital.

Utility of liquid-based cytologic examination of distal esophageal brushings in the management of Barrett esophagus: a prospective study of 45 cases.

Introduction: The goal of Barrett esophagus surveillance is to identify high-grade dysplasia (HGD) for eradication. Surveillance programs currently rely on limited histologic sampling; however, the role of cytology in this setting is not well studied.

Materials And Methods: From December 1, 2011 to March 30, 2014, 45 patients underwent 4 circumferential brushings of the distal tubular esophagus followed by standard 4-quadrant biopsies.

Interventional endoscopy.

Interventional endoscopy is a general label given to endoscopic procedures used to deal with a variety of gastrointestinal disorders. The interventional endoscopic procedures of interest in this review are those used specifically with gastric disorders. They include hemostasis, endoscopic ultrasound, endoscopic mucosal resection, stenting, percutaneous endoscopic gastrostomy tube placement and photodynamic laser therapy.

Magnification endoscopy as a reliable tool for the early diagnosis of rejection in living related small bowel transplants: a case report.

The purpose was to determine whether magnification endoscopy (ME) accurately diagnosed rejection in living related small bowel transplants (LRSBTx) during initial morphological adaptation of segmental intestinal grafts. The small bowel recipient was a 44-year-old woman with short gut syndrome following multiple bowel surgeries for familial adenomatous polyposis. ME was enhanced by chromoendoscopy staining.

Nutrition in acute pancreatitis.

Pancreatitis is a common disorder. Numerous factors have been implicated in the pathogenesis of acute and chronic pancreatitis, but the exact mechanisms of these conditions are still poorly understood. Depending on the cause of the disorder, patients who have pancreatitis are usually not malnourished and are able to eat within 5 to 7 days of disease onset.

Dietary cow's milk protein does not alter the frequency of diabetes in the BB rat.

One theory of the pathogenesis of IDDM proposes that exposure to cow's milk proteins triggers the disease in genetically susceptible individuals. We tested this hypothesis in the BB/Wor rat model of human IDDM. Diabetes-prone (DP) BB/Wor rats spontaneously develop IDDM.

Giant gastric ulceration associated with antiphospholipid antibody syndrome.

The anticardiolipin or antiphospholipid antibody syndrome is characterized by an increased incidence of venous and arterial thromboses. This syndrome may occur in association with systemic lupus erythematosus or independently. Gastroenterological manifestations have included Budd-Chiari syndrome, hepatic infarction, esophageal necrosis with perforation, intestinal ischemia and infarction, pancreatitis, and colonic ulceration.

The effect of recombinant cytokines on [14C]-aminopyrine accumulation by isolated canine parietal cells.

Interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-alpha) have been shown to inhibit basal and pentagastrin-stimulated gastric secretion in rats and histamine-stimulated secretion in dogs. IL-1 also reduces the severity of ethanol and stress-induced gastroduodenal damage. The aim of this study was to examine the effects of human recombinant IL-1 alpha and TNF-alpha on enzymatically dispersed and enriched (> 90%) parietal cells stimulated with histamine, histamine plus 3-isobutyl-1-methylxanthine (IMX) or carbachol (all 10(-5) M).

Hepatic schistosomiasis: report of two cases and literature review.

Two Filipino patients were referred for evaluation of abnormal liver enzymes. Both patients were known to come from regions endemic for Schistosoma japonicum. The clinical laboratory and radiological features of these patients are presented.

Use of albumin as a volume expander.

In some hospitals, albumin products account for 10% of the pharmaceutical budget. As much as 60% of these prescriptions are empiric, and from 40 to 70% of albumin that is administered is given for inappropriate reasons. Although the reasons for albumin administration vary, prevention or reversal of hypovolemia is part of the reason in the majority of cases.

The role of albumin in human physiology and pathophysiology, Part III: Albumin and disease states.

The serum albumin level is one of several clinical parameters of the status of general health. There is a marked correlation between low albumin levels and the incidence of morbidity and mortality in hospitalized patients. Therefore, it is not surprising to find that hypoalbuminemia is a common finding among hospitalized patients.

Role of albumin in human physiology and pathophysiology.

Albumin is one of the major products of hepatic protein synthesis. Although it is a small molecule, it is an important diagnostic and prognostic determinant, as well as a useful therapeutic agent. A review of the evolution and structure of albumin as well as a description of its colloidal and buffering properties is presented.

Continuous v intermittent cimetidine infusion in critically ill hospitalized patients: role of TPN admixture as drug vehicle.

Previous studies suggest that continuous or intermittent cimetidine infusion provides a stable and sustained therapeutic blood concentration that maintains a gastric pH greater than 4.0. Twenty-seven patients receiving cimetidine were randomized to one of five treatments.

Overview of gastrointestinal disorders due to diabetes mellitus: emphasis on nutritional support.

Gastrointestinal disorders associated with diabetes mellitus have a prevalence rate of 30 to 75%. The most prominent disorders are gastroparesis, diarrhea, and constipation. Severity of symptoms range from mild to severe with the most affected patients being at risk for the development of protein calorie malnutrition.

Histamine H2 receptor stimulation increases gastric emptying in monkeys.

We studied the effect of the specific H2 receptor agonist dimaprit on gastric emptying using a dye dilution technique in five chair-adapted rhesus monkeys to determine simultaneously gastric emptying and H+ secretion. Continuous subcutaneous injections of either saline alone or dimaprit (15, 30, 60, 120, and 240 nmol.kg-1.

A prostaglandin endoperoxide analog increases gastric emptying and suppresses gastric secretion in rhesus monkeys.

The effects of a stable endoperoxide analog, U-46619, were studied in five conscious chair-adapted rhesus monkeys. A dye dilution technique was used to determine simultaneously gastric fractional emptying, fluid output and ion output. A continuous infusion of either saline or U-46619 (0.

Effect of a prostaglandin F2 alpha analog on gastric emptying and secretion in rhesus monkeys.

The effects of 15(S)-15 methyl prostaglandin (PG) F2 alpha (mePGF2 alpha) on gastric emptying and secretion were studied in five conscious chair-adapted rhesus monkeys. A dye dilution technique was used to determine simultaneously fractional emptying rate, hydrogen ion (H+) output, fluid output and H+ concentration of the gastric juice. A continuous s.
