The practical approach to the investigation of diarrhea must be logical and based on anatomic considerations. The site of the underlying disorder may be determined by the clinical picture, and the logic of investigation will be influenced by the history. Important specific investigation in a case of
OBJECTIVE
Direct pancreatic function tests (PFTs) are often used to diagnose chronic pancreatitis (CP). We aimed to determine the temporal relationship between an abnormal PFT result, cross-sectional imaging, and clinical symptoms.
METHODS
All patients referred for endoscopic ultrasound (EUS) and
In a healthy subject infusions of either secretion or glucagon caused no diarrhea. A combinations of gastrin and glucagon induced severe watery diarrhea immediately after the end of the 3 hour infusion. No diarrhea occurred from the combination of secretin and gastrin.
We present a case of Zollinger Ellison Syndrome (ZES), that manifested itself as chronic diarrhea, without the presence of peptic ulcer disease. The purpose of this work in to report a case of ZES with and unusual clinical manifestation and to review the diagnostic methods (gastrin, secretin
Exocrine pancreatic insufficiency has been observed in some diabetics with peripheral neuropathy and diarrhea. Several mechanisms may be responsible for this insufficiency: (1) pancreatic atrophy, (2) disruption of the cholinergic enteropancreatic reflexes, or (3) elevated serum levels of peptides
A case of watery diarrhea, hypokalemia and hypercalcemia associated with an islet cell tumor was described. A 62-year old man exhibited frequent watery diarrhea and hypokalemia for two years. He had no peptic ulcer and serum gastrin level was normal. His serum calcium was abnormally high and serum
A patient with severe watery diarrhea and a non-beta islet cell carcinoma of the pancreas producing five hormones (secretin, serotonin, enteroglucagon, vasoactive intestinal polypeptide, and pancreatic glucagon) is described. We have demonstrated massive pancreatic hypersecretion to be a major
Secretin, a gastrointestinal (GI) hormone, was reported in a preliminary study to improve language and behavior in children with autism/pervasive developmental disorder (PDD) and chronic diarrhea. To determine the efficacy of secretin, we completed a double-blind, placebo-controlled, crossover (3
To document the existence of primary pancreatic secretinoma in patients with watery diarrhea syndrome (WDS) and achlorhydria and establish secretin as a diarrheogenic hormone.
Vasoactive intestinal peptide (VIP) has been widely accepted as the main mediator of WDS. However, in 1968, Zollinger et al
Previous trials of secretin for the treatment of autism have utilized a single or double dose administered intravenously. This is a report of a double-blind, randomized, controlled crossover trial of transdermally applied secretin in 15 children diagnosed with autism or pervasive developmental
OBJECTIVE
Anecdotal reports on the efficacy of secretin in autism raised great hopes for the treatment of children with this disorder. Initial single-dose, randomized, controlled trials failed to demonstrate any therapeutic effects of secretin. The present study is the first to test the outcome of
In a prospective study the pancreatic duct diameter was measured sonographically before and after secretin stimulation in 20 healthy controls and 59 patients with upper abdominal pain, weight loss, and/or diarrhea. Whereas healthy controls and patients without pancreatic disease after secretin
BACKGROUND
Endoscopic ultrasound and endoscopic secretin pancreatic function test may be combined in a single endoscopic session (EUS/ePFT) to diagnose chronic pancreatitis (CP).
OBJECTIVE
Our primary aim was to assess the correlation and concordance of combined EUS and secretin ePFT bicarbonate
BACKGROUND
Autism is a severe developmental disorder with poorly understood etiology. A recently published case series describes 3 autistic children with gastrointestinal symptoms who underwent endoscopy and intravenous administration of secretin and were subsequently noted by their parents to
Tumoral secretions and pathophysiology of diarrhea were studied in 1 patient with pancreatic cholera. High concentrations of vasoactive intestinal peptide were found in both systemic blood and tumoral extracts, together with increased plasma levels of calcitonin and protaglandins E and Falpha.
