PURPOSE: Increasing evidence suggests that polymorphisms in innate immunity genes are associated with Helicobacter pylori-induced inflammation and may influence susceptibility in developing noncardia gastric cancer. Therefore, we investigate the effect of polymorphisms of innate immunity genes and interactions with environmental factors in the Korean population. MATERIALS AND METHODS: We genotyped four polymorphisms of TLR2 (rs1898830), TLR4 (rs10983755 and rs10759932), and CD14 (rs2569190) in a case-control study of 487 noncardia gastric cancer patients and 487 sex- and age-matched healthy controls. Polytomous logistic regression models were used to detect the effects of genetic polymorphisms and environmental factors, which were stratified by the histological type of gastric cancer. RESULTS: TLR4 rs10983755 A carriers were found to have higher risk of intestinal-type noncarida gastric cancer than G homozygotes (odds ratio [OR], 1.41; 95% confidence interval [CI], 1.01 to 1.97), but other genetic variants showed no association with the risk of noncardia gastric cancer. Among H. pylori-positive participants, smokers carrying TLR4 rs10983755 A had a higher risk of intestinal-type gastric cancer than nonsmoking TLR4 rs10983755 G homozygotes (OR, 4.28; 95% CI, 2.12 to 8.64). In addition, compared with tap water, other drinking water sources during childhood were found to be associated with the elevated risk of intestinal-type gastric cancer, and these associations were slightly stronger among TLR4 rs10983755 A carriers. CONCLUSION: The genetic polymorphisms of innate immunity genes are associated with the development of intestinal-type noncardia gastric cancer and these associations may differ in accordance to an exposure to certain environmental factors.

BACKGROUND/AIMS: Mucosa-associated lymphoid tissue (MALT) lymphoma of the stomach is an uncommon disease. Bone marrow involvement is reported even in patients with only a mucosal lesion. We evaluated the prevalence and risk factors of marrow involvement and its implications for diagnosis and treatment. METHODS: In total, 132 patients who were diagnosed with gastric MALT lymphoma at the National Cancer Center in Korea between January 2001 and December 2016 were enrolled in the study. The patient data were collected and analyzed retrospectively. RESULTS: Of the 132 patients, 47 (35.6%) were male, with a median age of 52 years (range, 17 to 81 years). The median follow-up duration was 48.8 months (range, 0.5 to 169.9 months). Helicobacter pylori infection was detected in 82 patients (62.1%). Most patients (80.3%) had stage IE1 according to the modified Ann Arbor staging system. Ninety-two patients underwent bone marrow evaluation, and four patients (4.3%) had marrow involvement. Of these patients, one presented with abdominal lymph node involvement, while the other three had stage IE1 disease if marrow involvement was disregarded. All three patients had no significant symptoms and were monitored after local treatment without evidence of disease aggravation. CONCLUSIONS: Bone marrow involvement was found in 4.3% of the patients with gastric MALT lymphoma. Bone marrow examination may be deferred because marrow involvement does not change the treatment options or outcome in gastric MALT lymphoma confined to the stomach wall.

Chronic idiopathic inflamatory bowel disease, espcaially Crohn's disease, is frequently complicated with low gastrointestinal stricture. Besides medical treatment of active inflammation, there is no specific, conservative approach to this complication, Repetitive surgery with extensive resections, leading to short bowel syndrome, is often necessary. Balloons have been used for a variety of gastrointestinal stenoses including esophageal, small intestinal, and colonic stricture. Balloon dilation offers many theoretical advantages (safety, and patient comfort) over dilation with bougies. Especially, the availability of large diameter balloon dilators, which pass through the biopsy channel of standard endoscopes (through-the scope balloon or TTS balloon), has promised efficient direct-vision dilatation of strictures without the need of guide wires or fluoroscope. We report a case of colonic Crohn's stricture dilated successfully using TTS balloon catheter.

Collagenous colitis is characterized clinically by chronic watery diarrhea and pathologically by increased subepithelial collagen deposition associated with an inflammatory infiltrate in the lamina propria. Its etiology is still unclear, although a variety of associated diseases such as rheumatic syndromes, scleroderma, and thyroid diseases have been reported. We report a case of collagenous colitis following the prolonged use of NSAIDs. A 72-year-old woman who has taken NSAIDs for many years due to some dermatologic problems was admitted to the hospital because of chronic watery diarrhea and colicky abdominal pain of 3 months duration. There was no abnormal physical finding except cachectic appearance due to weight loss of 10kg during 3 months. Stool examination for ova and parasites and fat was negative, and stool culture for bacterial pathogens was negative. In complete blood count, there were relative eosinophila and mild anemia. Total serum protein and albumin was low, and thyroid function, RA factor, FANA were all normal. Results of upper and lower gastrointestinal contrast radiographs were normal. Sigmoidoscopy revealed normal colonic mucosa but she had a thick subepithelial collagenous deposit and chronic inflammation in lamina propria on colonic biopsy. Based on the above findings, she was diagnosed as collagenous colitis. Diarrhea improved after withdrawing NSAIDs and the treatment with oral prednisolone. In the post-treatment biopsy, the thickness of the collagen hand was diminished. Collagenous colitis is now recognized as one of the common causes of chronic diarrhea of obscure origin and NSAIDs may play an etiological role in some patient with collagenous colitis.
