Background/Aims:
Effect of proton pump inhibitor (PPI) use on the risk of hipfracture is controversial. This study aimed to clarify the association between PPIuse and hip fracture risk using a large cohort.
Methods:
This study recruited participants from the nationwide cohort (n =1,025,340). After exclusion of participants who had hip fractures or were aged less than 40 years during the baseline period (2002 to 2004), 371,806 participants were followed to 2013. Participants prescribed PPIs for more than 90 days during baseline period were defined as users. Fracture cases were defined when participants were hospitalized with claims of a hip fracture.
Results
During 4,159,343 person-years of follow-up, fractures developed more oftenin PPI users than in nonusers (relative risk [RR], 1.787; 95% confidence interval [CI], 1.260 to 2.534; p = 0.002). The results persisted after adjusting for age, sex, andmany drugs relevant to osteoporosis or influential in bone health. Furthermore,fracture risk associated with PPI use increased with duration of use ( p trend < 0.001). The fully adjusted RRs of hip fracture development were 1.350 (95% CI, 1.203 to 1.515) for 1- to 90-day users, 1.487 (95% CI, 0.957 to 2.311) for 91- to 180-day users, and 1.771 (95% CI, 0.931 to 3.368) for > 180-day users. The positive association between PPI use and fracture was also confirmed in a subgroup with health screening data where further adjustment for body mass index, smoking status, alcohol consumption, and physical activity was available (adjusted RR, 2.025; 95% CI, 1.151 to 3.564, p = 0.014). Conclusions: PPI use is associated with hip fracture development.

BACKGROUND/AIMS: Safety of endoscopic procedures has been a major issue over the last 10 years. Most endoscopy units use 2% glutaraldehyde and automated endoscope reprocessors (AERs) for disinfecting gastrointestinal endoscopes. We attempted an in-use evaluation of the current reprocessing procedures. METHODS: Thirty flexible endoscopes were randomly collected just after upper endoscopic examinations and were disinfected using 2% glutaraldehyde in an AER. Cultures were taken from biopsy channels (S-1), tip of the insertion tubes (S-2), umbilical cords (S-3), and angulation knobs (S-4). RESULTS: In 63.3% (19/30) of endoscopes, there was no microbial contamination after disinfection procedures. The culture positive rates of S-1, S-2, S-3, and S-4 samples were 20.0%, 0.0%, 3.3%, and 20.0%, respectively. Microorganisms of 13 species were identified, but there was no pathogen related with reported infectious complications after endoscopic procedures. CONCLUSIONS: Current disinfection procedure using 2% glutaraldehyde and an AER appears to be very effective in decontaminating patient-used endoscopes. Low level microbial contamination of endoscopes after conventional reprocessing methods may not impose great risk on patients.

BACKGROUND: Among various methods for measuring colon transit time, radio-opaque marker study is simple, reproducible and economical method. The commonly used marker, Sitzmarks (Konsyl Pharmaceuticals Inc. Texas) had limitation in its use due to expensiveness and difficulty in importation. We thought that the new domestic marker comparable to Sitzmarks is necessary and made a Kolomark (Korean colon marker)TM. The comparison of radio-opaqueness and the measurement of colon transit times by two markers were done. METHODS: In two 1000 ml beakers, 350 ml of rice-gruel, several chicken-bones and ten rings of Sitzmarks and KolomarkTM were mixed separately. Then, X-ray films of the two beakers were taken. The digital image file was analyzed by Image and the value of pixels were obtained. These were repeated five times. Colon transit times were measured in 60 healthy persons stratified by age, 30 by Sitzmarks and 30 by KolomarkTM. RESULTS: The mean value of pixel of KolomarkTM was much lower than that of Sitzmarks. The difference between background or beaker and KolomarkTM was much greater than that of Sitzmarks . There was no significant difference between colon transit time studied by Sitzmarks and KolomarkTM. CONCLUSION: KolomarkTM, a more radio-opaque and cheaper marker than Sitzmarks will be applied usefully for measuring colon transit time.

BACKGROUND: Crohn's disease (CD) is a chronic inflammatory disease that has difficulty in treatment due to various complications and frequent recurrence. There have been many studies on the clinical aspects of CD in western countries, however there have been few studies in Korea. We try to perform this study to elucidate the clinical features of CD in Korea. METHODS: We retrospectively reviewed the medical records of 62 patients diagnosed as CD in Samsung Medical Center from October 1994 to July 1999 and investigated their clinical features. RESULTS: Male to female ratio was 1.7:1 and the mean age at diagnosis was 29.6 years. The most common symptom was abdominal pain (58%), followed by diarrhea. Perianal lesions were observed in 27 cases (44%) of 62 patients. Fistula was the most common (60%) among the perianal lesions, followed by abscess, fissure, and stricture. Extraintestinal manifestations were observed in 23 cases (37%) of 62 patients. Arthritis was the most common (44%), followed by oral, skin, and ocular lesions. All patients were classified into three groups on the basis of disease extent by the radiologic and endoscopic findings; combined type (66%), colitis alone (23%), and small bowel disease alone (11%). Empirical anti-tuberculous medications were administered to 28 cases (45%) of 62 patients before CD was diagnosed. The presenting features were classified into inflammatory (71%), fistulizing (14.5%), and fibrostenotic (14.5%) type. Operation was performed in 31 cases (50%) of 62 patients during clinical course. The causes of operation were fistulizing complication (48%), fibrostenotic obstruction (32%), and indefinite diagnosis (20%). CONCLUSION: We noticed little difference in the clinical features of CD in Korea compared to those of western countries. And, intestinal tuberculosis should be considered in differential diagnosis of CD in endemic areas of tuberculosis like Korea.

BACKGROUND/AIMS: The endoscopic and clinical findings of gastrointestinal (GI) Burkitt lymphoma in Koreans are not well known. METHODS: From January 1995 to July 2007, 80 patients (47 adults and 33 children) were diagnosed with Burkitt lymphoma at our institution. The clinical and endoscopic manifestations were analyzed in the adult patients (n=20, median age=52 yr) with GI Burkitt lymphoma. RESULTS: The most frequent symptom was abdominal pain (50%) followed by epigastic soreness (30%). Among the 20 patients with GI Burkitt lymphoma, 11 (55%) had gastric lesions, 4 (20%) had colonic lesions, 3 (15%) had both gastric and duodenal lesions, 1 (5%) had both gastric and colonic lesions, and 1 (5%) had gastric, duodenal and colonic lesions. For the 13 patients who had endoscopic pictures available, the most common type of disease was the ulcerative type (38.5%) followed by the ulcerofungating and ulceroinfiltrative types (23.1% and 23.1%, respectively). Most of the patients were diagnosed with advanced disease. The most common clinical stage was stage IVE (60%) by the Musshoff staging system. All 20 patients received combination chemotherapy, and the 5-year survival rate was 64%. CONCLUSIONS: For patients with GI Burkitt lymphoma, the most commonly involved site was the stomach. Most lesions were ulcerative with or without fungating morphology. Considering the advanced stage of most patients, the prognosis after systemic chemotherapy was favorable.

BACKGROUND/AIMS: In western countries, symptomatic diverticulitis develops in about 20% of the population with colonic diverticula, and it is mainly located at the left-sided colon. The clinical characteristics of diverticulitis have rarely been investigated although its incidence is increasing in Asia including Korea. The aim of this study was to compare diverticulitis with asymptomatic diverticulosis and to compare the clinical characteristics of right-sided diverticulitis with those of left-sided diverticulitis. METHODS: We retrospectively investigated the medical records of the patients who had symptoms and signs of diverticulitis. Their diagnosis was confirmed with computed tomography, barium study, colonoscopy and/or operations at Samsung Medical Center from September 1998 to February 2002. The control cases of asymptomatic and incidental diverticulosis were randomly selected during routine health check-up after matching age and sex. RESULTS: Twenty-seven patients with diverticulitis (male : female=14 : 13) were included. The mean age was 53 (27~86). The ratio of right and left diverticulitis was 20:7, which was similar to the ratio of diverticulosis. The complications, especially perforation, were more frequent in the patients with left-sided diverticulitis (p<0.05). CONCLUSIONS: Colonic diverticulitis is more prevalent at the right colon and left colonic diverticulitis has more complications than right colonic diverticulitis in Korea.

BACKGROUND: Transforming growth factor-beta (TGF-beta) is a potent inhibitor of epithelial cell growth. However, carcinoma cells, unlike normal cells, can escape from negative regulation by TGF-beta through lack of expression or mutation of TGF-beta receptor gene. In this study, we investigated the role of TGF-beta1 and TGF-beta type II receptors (TbetaR-II) in the progression of gastric cancer. METHODS: We analyzed TGF-beta1 and TbetaR-II mRNA expression semi-quantitatively, measured by comparative RT-PCR using GAPDH, in 23 patients who underwent gastric resection for gastric cancer. We analyzed the relationship between the clinicopathologic findings and the level of the TGF-beta1 and TbetaR-II mRNA expression in carcinoma tissues and in adjacent normal tissues of gastric cancer. RESULTS: (1) TGF-beta1 and TbetaR-II mRNA were expressed in all of the carcinoma tissues and adjacent normal tissues without statistical difference in the level of the expression. (2) The level of TGF-beta1 mRNA expression was higher in patients with early gastric cancer, negative lymph nodes or negative perineural invasion. There was no significant correlation between the level of TGF-beta1 mRNA expression and several parameters such as age, gender, tumor size, differentiation, Lauren's classification, and vascular invasion. (3) There was no significant correlation between the level of TbetaR-II mRNA expression and several prognostic variables described above. (4) There was significant correlation between the level of TGF-beta1 and TbetaR-II mRNA in carcinoma tissues. CONCLUSION: The above data indicates that TGF-beta1 may contribute in the early stages of gastric carcinogenesis. Further studies are required to clarify the role of TGF-beta 1 in gastric carcinogenesis.
