TL;DR: Recommendations are made regarding diagnostic measures to screen for iron- and other anemia-related deficiencies regarding the triggers for medical intervention, treatment goals, and appropriate therapies.
Journal ArticleDOI
Impaired accommodation of proximal stomach to a meal in functional dyspepsia
TL;DR: Patients with functional dyspepsia have impaired accommodation of the proximal stomach to a meal, temporarily related to symptom induction, and they suffered more symptoms in response to the meal.
Journal ArticleDOI
Faecal calprotectin levels in infants with infantile colic, healthy infants, children with inflammatory bowel disease, children with recurrent abdominal pain and healthy children.
TL;DR: Faecal calprotectin concentration, a measure of intestinal inflammation, in infants and children with abdominal pain, was measured by an enzyme‐linked immunosorbent assay kit in spot stool samples in 76 infants with typical infantile colic, 7 infants with transient lactose intolerance and 27 healthy infants.
Journal ArticleDOI
Experimental colitis in animal models.
Hak-San Kim,Arnold Berstad +1 more
TL;DR: It appears that all models of colon inflammation in the rat, mouse, or rabbit produce increased amounts of eicosanoids similar to that found in human colitis, and no animal model of induced or spontaneous inflammation of the colon is analogous to human ulcerative colitis in etiology, course of disease activity, or histology.
Journal ArticleDOI
Low vagal tone and antral dysmotility in patients with functional dyspepsia
Trygve Hausken,Sven Svebak,Ingvard Wilhelmsen,Tone Tangen Haug,K. Olafsen,E. Pettersson,Kristian Hveem,Arnold Berstad +7 more
TL;DR: Antral motility was reduced by mental stress in the healthy persons, but not in FD patients, and the lack of stress‐related reduction of motility among patients with FD may be a consequence of poor vagal tone.
