Combined endoscopy, aspiration, and biopsy analysis for identifying infectious colitis
in patients with ileocecal ulcers.
in infants can result from bacterial, viral, or parasitic agents, and is a common cause of colitis in the pediatric population (Piccoli, 2012).
The accordion sign has also been observed with colonic edema secondary to cirrhosis and in Crohn's disease, ischemic colitis, lupus vasculitis, and infectious colitis
(14-16) In the setting of acute diarrhea, it has been used in place of microscopic fecal leukocyte analysis to assist in the diagnosis of infectious colitis
, such as bacillary dysentery or Clostridium difficile-induced pseudomembranous colitis.
coli O157, and a diagnosis of infectious colitis
with associated hemolytic uremic syndrome was confirmed.
Microscopic patterns of injury associated with medications may mimic common entities (Table 1), like mucosal erosions/ulcerations, inflammatory bowel disease (IBD), ischemic colitis, infectious colitis
, microscopic colitis, or graft-versus-host disease (GVHD).
Comparison was made with 93 healthy controls while individuals with infectious colitis
, ischemic colitis, intestinal tuberculosis, and autoimmune diseases were excluded.
Primary differential diagnoses are infectious colitis
(including Clostridium difficile), gastroenteritis, irritable bowel syndrome (IBS/IBD), Crohn's disease, ulcerative colitis, celiac disease, cystic fibrosis, anorexia nervosa, hyperthyroidism, diabetes, food/medication allergy, lactose intolerance, constipation with encopresis, and laxative use (Hyams, 2005; Yamada, Hasler, Inadomi, Anderson, & Brown, 2005).
Two probably were infectious colitis
caused by Escherichia coli O157; the fourth was not diagnostic of ischemic or infectious colitis
