AIM： To compare the antiviral efficacy of adefovir （ADV） in lamivudine （LMV）-resistant patients with LMV treatment in nucleoside-naive patients, using serum samples collected sequentially during the course of treatment progressing from LMV to ADV.METHODS： Forty-four patients with chronic hepatitis B （CHB） were included. The patients were initially treated with LMV and then switched to ADV when LMV resistance developed. Antiviral efficacy was assessed by measuring the following： reduction in serum HBV DNA from baseline, HBV DNA negative conversion （defined as HBV DNA being undectable by the hybridization assay）, and HBV DNA response （either HBV DNA level ≤ 10^s copies/mL or a ≥ 2 log10 reduction from baseline HBV DNA level）.RESULTS： After two and six months of treatment, HBV DNA reduction was greater with LMV compared to ADV treatment （P = 0.021）. HBV DNA negative conversion rates were 64% and 27% after one month of LMV and ADV treatment respectively （P = 0.001）. Similarly, HBV DNA response rates were 74% and 51% after two months of LMV and ADV treatment respectively （P = 0.026）. The time taken to HBV DNA negative conversion and to HBV DNA response were both delayed in ADV treatment compared with LMV.CONCLUSION： The antiviral efficacy of ADV in LMV-resistant patients is slower and less potent than that with LMV in nucleoside-naive patients during the early course of treatment.

AIM： To investigate prevalence of C/onorchis sinensis in patients with gastrointestinal symptoms, and the relation of the infection to hepatobiliary diseases in 26 hospitals in Korea. METHODS： Consecutive patients who had been admitted to the Division of Gastroenterology with gastrointestinal symptoms were enrolled from March to April 2005. Of those who had been diagnosed with clonorchiasis, epidemiology and correlation between infection and hepatobiliary diseases were surveyed by questionnaire. RESULTS： Of 3080 patients with gastrointestinal diseases, 396 （12.9%） had clonorchiasis and 1140 patients （37.2%） had a history of eating raw freshwater fish. Of those with a history of raw freshwater fish ingestion, 238 （20.9%） patients had clonorchiasis. Cholangiocarcinoma was more prevalent in C. sinensis-infected patients than nonnfected patients [34/396 （8.6%） vs 145/2684 （5.4%）, P = 0.015]. Cholangiocarcinoma and clonorchiasis showed statistically significant positive cross-relation （P = 0.008）. Choledocholithiasis, cholecystolithiasis, cholangitis, hepatocellular carcinoma, and biliary pancreatitis did not correlate with clonorchiasis. CONCLUSION： Infection rate of clonorchiasis was still high in patients with gastrointestinal diseases in Korea, and has not decreased very much during the last two decades. Cholangiocarcinoma was related to clonorchiasis, which suggested an etiological role for the parasite.

AIM: To evaluate the association between alcoholic liver disease(ALD) and bone fractures or osteoporosis. METHODS: Non-randomized studies were identified from databases(Pub Med, EMBASE, and the Cochrane Library). The search was conducted using Boolean operators and keywords, which included "alcoholic liver diseases", "osteoporosis", or "bone fractures". The prevalence of any fractures or osteoporosis, and bone mineral density(BMD) were extracted and analyzed using risk ratios and standardized mean difference(SMD). A random effects model was applied. RESULTS: In total, 15 studies were identified and analyzed. Overall, ALD demonstrated a RR of 1.944(95%CI: 1.354-2.791) for the development of bone fractures. However, ALD showed a RR of 0.849(95%CI: 0.523-1.380) for the development of osteoporosis. BMD was not significantly different between the ALD and control groups, although there was a trend toward lower BMD in patients with ALD(SMD in femur-BMD:-0.172, 95%CI:-0.453-0.110; SMD in spine-BMD:-0.169, 95%CI:-0.476-0.138). Sensitivity analyses showed consistent results. CONCLUSION: Current publications indicate significant associations between bone fractures and ALD, independent of BMD or the presence of osteoporosis.

We report a case of gastric penetration caused by accidental ingestion of a chicken bone in a 42-year old woman with a partially wearing denture. Three days ago, she accidentally swallowed several lumps of poorly-chewed chicken. Physical examination disclosed mild tenderness in the periumbilical area. Abdominal Computed tomography (CT) showed a suspicious penetration or perforation of the stomach wall measuring about 3 cm, by a linear radiopaque material at the lesser curvature of the antrum. The end of a chicken bone was very close to but did not penetrate the liver. Endoscopic examination revealed a chicken bone that penetrated into the prepyloric antrum. The penetrating chicken bone was removed with grasping forceps. Five endoscopic clips were applied immediately at the removal site and the periumbilical pain resolved promptly. After removal of the chicken bone, the patient was treated with conservative care for three days, after which she was completely asymptomatic and discharged without complication. To treat gastric penetration by a foreign body, endoclipping can be a useful method in patients with no signs or symptoms of peritoneal irritation.

AIM:To determine the association of hOGG1 (8-oxoguanine glycosylase I,OGG1) polymorphism of Ser326Cys substitution with colon cancer risk and possible interaction with known environmental risk factors. METHODS:A case-control study with 125 colon cancer cases and 247 controls was conducted, RESULTS:There was no major difference in Ser326Cys genotype distribution between cases and *** meat intake tended to increase the odds ratio for colon cancer with an OR of 1.72 (95 % confidence interval;CI=1.12-2.76). Such tendency was more prominent in Cys/Cys carriers (OR=4.31,95 % CI=1.64-11.48),but meat intake was not a significant risk factor for colon cancer in Ser/Ser or Ser/ Cys *** OR for colon cancer was elevated with marginal significance in smokers who were Cys/Cys carriers (OR=2.75,95 % CI=1.07-7.53) but not in Ser/Ser or Ser/ Cys carriers. CONCLUSION:These results suggest that the hOGG1 Ser326Cys polymorphism is probably not a major contributor to individual colon cancer susceptibility overall,but the Cys/ Cys genotype may alter the impact of some environmental factors on colon cancer development.

A Killian-Jamieson diverticulum （KID） is an unfamiliar and rare cervical esophageal diverticulum. This diverticulum originates on the anterolateral wall of the proximal cervical esophagus through a muscular gap （the Killian-Jamieson space） below the cricopharyngeal muscle and lateral to the longitudinal muscle of the esophagus. To date, only surgical treatment has been recommended for a symptomatic KJD due to its close proximity to the recurrent laryngeal nerve and the concern of possible nerve injury. Recently, traditional open surgery for a symptomatic KJD is being challenged by the development of new endoscopic techniques and devices. We present here a case of a symptomatic KID that was successfully treated with the flexible endoscopic diverticulotomy using two new devices. An isolated-tip needle-knife papillotome （Iso-Tome） was used for the dissection of the tissue bridge of the diverticulum. And a flexible overtube with a modified distal end （a fitted overtube） was used for adequate visualization of the tissue bridge of the diverticulum and protection of the surrounding tissue during dissection of the tissue bridge. Our successful experience suggests that the flexible endoscopic diverticulotomy with the use of appropriate endoscopicdevices can be a safe and effective method for the treatment of a symptomatic KJD.

Primary intestinal lymphangiectasia(PIL) is a rare protein-losing enteropathy with lymphatic leakage into the small intestine. Dilated lymphatics in the small intestinal wall and mesentery are observed in this disease. Laboratory tests of PIL patients revealed hypoalbuminemia, lymphocytopenia, hypogammaglobulinemia and increased stool α-1 antitrypsin clearance. Cell-mediated immunodeficiency is also present in PIL patients because of loss of lymphocytes. As a result, the patients are vulnerable to chronic viral infection and lymphoma. However, cases of PIL with chronic viral infection, such as human papilloma virus-induced warts, are rarely reported. We report a rare case of PIL with generalized warts in a 36-year-old male patient. PIL was diagnosed by capsule endoscopy and colonoscopic biopsy with histological tissue confirmation. Generalized warts were observed on the head, chest, abdomen, back, anus, and upper and lower extremities, including the hands and feet of the patient.
