Upper gastrointestinal tract involvement of Crohn disease: clinical implications in children and adolescents
Eun Sil Kim, Mi Jin Kim
Clin Exp Pediatr. 2022;65(1):21-28.   Published online September 10, 2021
· Clinical manifestations of upper gastrointestinal (UGI) tract involvement in Crohn's disease (CD) are common but often clinically underestimated.
· Diagnosing CD by confirming inflammation of the UGI tract histologically is challenging because macroscopic and microscopic findings overlap with those of other diseases.
· Ongoing efforts are needed to enable a standardized assessment of UGI CD in the future.

Seung Min Lee, Seok Woo Park, Yun Hee Kim, Ji Eun Lee, Young Jin Hong, Byong Kwan Son
Clin Exp Pediatr. 2004;47(10):1124-1127.   Published online October 15, 2004
Dieulafoy's lesion is an unusual cause of massive gastrointestinal bleeding resulting from the erosion of an abnormally large submucosal artery. Recently, improvement of endoscopic techniques has made effective hemostasis possible in most cases of Dieulafoy's lesion. Aspirin, which is an anti-inflammatory agent, increases the incidence of major upper gastrointestinal complications. Gastroduodenal mucosal injury associated with aspirin therapy in patients in...

Serum Pepsinogen Ⅰ, Ⅱ Levels and Upper Gastrointestinal Diseases in Children with H. pylori Infection
Je Woo Kim, Ki Sup Chung
Clin Exp Pediatr. 1998;41(2):200-208.   Published online February 15, 1998
Purpose : In H. pylori infection serum pepsinogen Ⅰ/Ⅱ ratio decreases and pepsinogen Ⅱ level is increased. Increased serum pepsinogen Ⅱ level correlates with pathologic severity of gastritis. We assayed serum pepsinogen Ⅰ, Ⅱ levels and pepsinogen Ⅰ/Ⅱ ratio to evaluate the relationship between the serum pepsinogen level and upper gastrointestinal diseases. Methods : One hundred and sixty-five children who had...
Recurrent Abdominal Pain in Children: Endoscopic Findings and Helicobacter pylori Infection
Cheol Ho Chang, Churl Young Chung
Clin Exp Pediatr. 1995;38(1):47-53.   Published online January 15, 1995

Recently, microscopic inflammation and Helicobacter pylori (H. pylori) infection have been suggested as possible causes of nonulcer dyspepsia in adults. The aim was to know the clinical significance of encoscopic findings and H. pylori infection in children with RAP. Methods : 128 children with RAP underwent...
