A mysterious disease was first reported from Korea when it had been observed during late spring 1951 in UN Forces operating in the central area close to the 38th parallel. The disease showed distinctive features which included high fever, low blood pressure, hemorrhagic tendency and acute renal failure. Historically it was apparently a similar disease to a clinical entity designated as Epidemic hemorrhagic fever in Manchuria or Hemorrhagic nephrosonephritis in Far Eastern Russia. After Lee Ho-Wang succeeded in demonstrating Hantaan virus which caused hemorrhagic fever with renal syndrome (HFRS), many studies has revealed various biological and epidemiological aspects of the disease. But the origin of the disease in Korea still remains unknown. This article tests some hypotheses which explain the origin of the disease and reviews the relation between the Korean War and HFRS. It is concluded that the emerging of HFRS would be closely related with the establishment of the munitions supply network in early 1951 in Chinese troop.

BACKGROUND/AIMS: Ulcerative colitis (UC) is a chronic inflammatory bowel disease with heterogeneous clinical features. Data on the disease course and prognosis of UC patients who have been regularly treated are lacking. We aimed to investigate relapse rates of UC in remission and factors related to relapse. METHODS: We retrospectively analyzed clinical courses of 84 patients (43 males, median age 43 years, ranged 20-73 years) diagnosed as UC at Ajou University Hospital between January 1997 and December 2005 based on clinical, endoscopic and pathologic findings, and who were regularly followed for at least one year after the remission. RESULTS: Study subjects consisted of 32 proctitis (38%), 21 left-sided colitis (25%), and 31 subtotal or total colitis (37%). Of 84 patients, relapse was observed in 52 patients (62%) during the follow-up period (ranged 1-9 years). The relapse rate was 24%, 41%, 51%, 65%, 71%, and 79% at 1 year, 2 years, 3 years, 4 years, 5 years and 6 years, respectively. Among sex, age, hemoglobin, ESR, and the extent of disease on admission, decrease of hemoglobin level was the only independent factor related to relapse (odds ratio=2.67, 95% CI (1.32-5.42), p<0.01). CONCLUSIONS: In Korea, relapse of UC in remission is not rare. Decrease of hemoglobin level is an independent risk factor related to its relapse, while the extent of disease is not.

BACKGROUND/AIMS: In western courtry, Helicobacter pylori (H. pylori) serology is a screening test for non-ulcer dyspepsia (NUD) before endoscopy in dyspeptic patients under 45 years old without alarm symptoms. The aim of this study was to determine the usefulness of H. pylori serology before endoscopy in Korea. METHODS: Six hundred and fifteen outpatients (M:F=339:276, mean age 43.6+/-13.8, range 15-81) with dyspepsia performed anti-H. pylori IgG (GAP or HM-CAP) and upper gastrointestinal endoscopy with biopsy. Exclusion criteria were alarm symptoms, history of gastrectomy, NSAID use and previous anti-H. pylori treatment. RESULTS: The prevalence of anti-H. pylori IgG was 61.0% in patients under and 40 years old and 63.8% in patients over 40 years old. There was no significant difference between age groups. For patients under and 40 years old, serology predicted all pathology except 5 gastric ulcer, 8 duodenal ulcer, 2 reflux esophagitis and 2 gastric submucosal tumor. The sensitivity and negative predictive value (76.7, 85.8%) in patients under and 40 years old were higher than that (61.9, 64.0%) in patients over 40 years old (p=0.037, p=0.001). CONCLUSIONS: H. pylori serology seems to be an acceptable screening test for NUD in dyspeptic patients under and 40 years old without alarm symptoms.
