Do medicine residents triage patients with gastrointestinal bleeding appropriately?

Background: Gastrointestinal specialists depend on internal medicine (IM) teams to accurately identify acute gastrointestinal bleeding (GIB). We evaluated whether IM residents' assessment of GIB correlated with the impressions of GI specialists during consultations at an inner-city university teaching hospital.

Methods: A questionnaire was distributed to house staff requesting GIB consultations and to the GI fellows performing the consults between August 2011 and April 2012.

A rare case of myeloid sarcoma presenting as an anorectal ulcer.

Myeloid Sarcoma is a rare tumor composed of myeloblasts occurring at an extramedullary site like bones, or various soft tissues. Myeloid sarcoma may involve the gastrointestinal tract very rarely either solitarily, or occurring simultaneously with acute myeloid leukemia. Its diagnosis is challenging and needs biopsy and immunohistochemical staining.

Glucose-dependent insulinotropic polypeptide stimulates the proliferation of colorectal cancer cells.

Although numerous epidemiological studies have provided convincing evidence for an increase in the prevalence of colorectal cancer (CRC) in obese individuals, the precise mechanisms involved have not been elucidated. Glucose-dependent insulinotropic polypeptide (GIP) is a gastrointestinal regulatory peptide whose primary physiologic role is to stimulate postprandial pancreatic insulin secretion. Like insulin, GIP has been linked to enhanced nutrient efficiency, which occurred during the course of evolution.

Racial differences in disease extent and severity in patients with ulcerative colitis: a retrospective cohort study.

Introduction: Ulcerative colitis (UC) is increasing in African-Americans (AA). The objectives of this study were to assess disease extent and severity in UC by race.

Methods: Disease extent and severity was assessed in UC outpatients evaluated at the University of Maryland and Baltimore VA from 1997 to 2005.
