BACKGROUND Polypectomy with cold biopsy forceps is a frequently used technique for removal of small, sessile, colorectal polyps. Jumbo forceps may lead to more effective polypectomy because of the larger size of the forceps cup. OBJECTIVE To evaluate the efficiency of cold jumbo biopsy forceps compared with standard forceps for polypectomy of small,(More)
BACKGROUND/AIMS Current therapy for gastroparesis with prokinetic agents is limited by options and side effects. One macrolide, erythromycin (ERY), is associated with possible sudden cardiac death from QT prolongation due to P450 iso-enzyme inhibition. An alternative, azithromycin (AZI), lacks P450 inhibition. We compared the effect on gastric emptying(More)
AIM To investigate, in the largest cohort to date, patient characteristics and associated risk factors for developing small intestinal bacterial overgrowth (SIBO) using the D-Xylose breath test (XBT). METHODS We performed a retrospective cross-sectional study to analyze patient characteristics who underwent the XBT for evaluation of SIBO. Diagnostic(More)
BACKGROUND Irritable bowel syndrome (IBS) is a chronic gastrointestinal disorder characterized by both visceral and somatic hyperalgesia, producing a similar effect seen with the central hypersensitivity mechanism in fibromyalgia (FM). OBJECTIVES The aim of the current study was to compare magnitudes of visceral and thermal hypersensitivity in IBS(More)
Current treatment options for the chronic gastrointestinal disorder irritable bowel syndrome (IBS) have long been limited to symptomatic treatments due to lack of pathophysiologic understanding of the syndrome. Within the past 10 years, however, a number of new pharmacological targets have been identified that may aid in the treatment of irritable bowel(More)
Gastroparesis refers to abnormal gastric motility characterized by delayed gastric emptying in the absence of mechanical obstruction. The most common etiologies include diabetes, post-surgical and idiopathic. The most common symptoms are nausea, vomiting and epigastric pain. Gastroparesis is estimated to affect 4% of the population and symptomatology may(More)
INTRODUCTION Functional dyspepsia (FD) is a highly prevalent and challenging disorder which impacts patients' quality of life and poses a considerable socioeconomic burden. Given the vagueness of the definition of FD based on the current Rome III criteria's expert opinion, the diagnosis of FD continues to be one of exclusion. Despite efforts to better(More)
N-Methyl-d-aspartic acid (NMDA) receptors are known to function in the mediation of pain and have a significant role in the development of hyperalgesia following inflammation. Serine phosphorylation regulation of NMDA receptor function occurs in a variety of conditions. No studies have demonstrated a change in phosphorylation of enteric NMDA receptors(More)
UNLABELLED Irritable bowel syndrome (IBS) is a common gastrointestinal disorder seen by gastroenterologists. We discuss some recent evidence for potential neural mechanisms that could contribute to somatic and visceral hyperalgesia in IBS patients. The combination of research studies of human IBS patients and studies of rats with delayed rectal(More)
Current pharmacologic treatments for gastroparesis have been disappointing due to the limited options available. Erythromycin ethylsuccinate is a potent prokinetic agent that stimulates gastric emptying. Recently, erythromycin has been linked to the occurrences of sudden cardiac death due to QT prolongation. Azithromycin is similar to erythromycin in(More)
