A Case of IgG4-Related Sclerosing Mesenteritis Associated with Crohn's Disease / 대한소화기학회지

Sclerosing mesenteritis (SM) is a rare disease characterized by chronic nonspecific mesenteric inflammation and fibrosis of unknown etiology. Some tumefactive SM shows diffuse accumulation of IgG4-positive plasma cells and is considered as a part of the spectrum of IgG4-related disease. An association between inflammatory bowel disease and IgG4-related disease has been indicated. A 45-year-old woman visited our hospital due to weight loss with intermittent lower abdominal discomfort. Pelvic ultrasound revealed a mass-like lesion in the abdominal wall and pelvis MRI demonstrated a 5.9 cm sized wall-enhancing mass with heterogeneous signal intensity from right adnexa to the abdominal wall. Tumor resection and adhesiolysis was done because of severe adhesion with the small bowel, colon, bladder, uterus, and abdominal wall. Appendectomy was also performed due to adhesion and edematous change. Histological examination of the resected mass showed findings that were compatible with IgG4-related SM. The resected appendix showed chronic granulomatous inflammation without evidence of tuberculosis. She was diagnosed with Crohn's disease after undergoing colonoscopy and CT enterography. Herein, we report a rare case of IgG4-related SM that occurred in conjunction with Crohn's disease.

Risk Factors of Delayed Bleeding after Colonoscopic Polypectomy: Case-Control Study / 대한소화기학회지

BACKGROUND/AIMS: Colonoscopic polypectomy is a valuable procedure for preventing colorectal cancer, but is not without complications. Delayed bleeding after colonoscopic polypectomy is a rare, but serious complication. The aim of this study was to identify risk factors of delayed bleeding after colonoscopic polypectomy. METHODS: A retrospective case-control study was conducted in a single university hospital. Forty cases and 120 controls were included. Data collected included comorbidity, use of antiplatelet agents, size and number of resected polyps, histology and gross morphology of resected polyps, endoscopist's experience, resection method, use of sedation, and use of prophylactic hemostasis. RESULTS: In univariate analysis, size, histology and number of resected polyps, endoscopist's experience, resection method and use of prophylactic hemostasis were significant risk factors for delayed bleeding after colonoscopic polypectomy. In multivariate analysis, risk of delayed bleeding increased by 11.6% for every 1 mm increase in resected polyp diameter (OR, 1.116; 95% CI 1.041-1.198; p=0.002). Number of resected polyps (OR, 1.364; 95% CI, 1.113-1.671; p=0.003) and endoscopist's experience (OR, 6.301; 95% CI, 2.022-19.637; p=0.002) were significant risk factors for delayed bleeding after colonoscopic polypectomy. CONCLUSIONS: Size and numbers of resected polyps, and endoscopist's experience were independent risk factors for delayed bleeding after colonoscopic polypectomy. More caution would be necessary when removing polyps with these factors.

A Case of Fetal Alcohol Syndrome with Secondary Amenorrhea / 대한내분비학회지

Alcohol ingestion during pregnancy can be damaging to embryonic and fetal development. A specific pattern of malformation, identified as Fetal alcohol syndrome, has been documented in 1~2 of every 1,000 live infant births Fetal alcohol syndrome is characterized by growth deficiency, facial abnormalities, cardiac defects, minor joint and limb abnormalities, as well as central nervous system dysfunction, including microcephaly, mental retardation and abnormal neurobehavioral development. However, there are few reports of fetal alcohol syndrome associated with hormonal abnormality or amenorrhea. Recently, a case of secondary amenorrhea, which developed in a 19-year-old woman with fetal alcohol syndrome, was experienced at our institute, but the exact cause of the amenorrhea was difficulty to find. Herein, this case is reported, with a review of the literature.
