There are no significant differences between 10-d sequential eradication therapy for H. pylori and any duration of standard triple treatment in Korean patients.

Cystic lung disease (CLD) is a group of lung disorders characterized by the presence of multiple cysts, defined as air-filled lucencies or low-attenuating areas, bordered by a thin wall (usually < 2 mm). The recognition of CLDs has increased with the widespread use of computed tomography. This article addresses the mechanisms of cyst formation and the diagnostic approaches to CLDs. A number of assessment methods that can be used to confirm CLDs are discussed, including high-resolution computed tomography, pathologic approaches, and genetic/ serologic markers, together with treatment modalities, including new therapeutic drugs currently being evaluated. The CLDs covered by this review are lymphangioleiomyomatosis, pulmonary Langerhans cell histiocytosis, Birt-Hogg-Dube syndrome, lymphocytic interstitial pneumonia/follicular bronchiolitis, and amyloidosis.

Objective: To report a case of oxaliplatin-combined chemotherapy-induced interstitial lung disease. Clinical Presentation and Intervention: A 57-year-old man was referred complaining of dyspnea and fever after treatment with an oxaliplatin-combined chemotherapeutic agent for metastatic colorectal cancer. Fever development and spontaneous subsidence were observed during the chemotherapeutic course repeatedly until the 9th cycle. A computer-tomographic (CT) scan revealed bilateral, peripherally distributed, patchy consolidation suggestive of an interstitial lung disease. As a confirmative step, video-assisted thoracoscopic surgical biopsy was attempted; the characteristic intraluminal organizing fibrous plug in the bronchioles and alveoli was seen. Corticosteroid therapy was administered, which rapidly improved the patient’s symptoms and chest CT findings. Conclusion: This case showed that oxaliplatin may be implicated in the etiology of interstitial lung disease, since withdrawal of the drug resulted in improvement of interstitial lung disease.

Background/Aims: Endoscopic mucosal resection can cure early gastric cancer. The risk of lymphatic metastasis is related to the depth of submucosal invasion by the mucosal malignancy, with a resection depth of 500μm generally accepted as a safe cut-off. However, excessive thinning induced by stretching of the resected tissue sometimes preventing a precise diagnosis. We studied the effects of stretching on different layers and sites of gastric tissue. Methods: Porcine stomachs were cut into 2.0×2.0 cm pieces, and pieces from body were stretched to 2.5, 3.0, and 3.5 cm. Pieces from the cardia, body, and antrum were also stretched to 3.0 cm. The thickness of each layer was measured and analyzed statistically. Results: Whole gastric wall and submucosal layers showed gradual thinning, with stretching to 3.5 cm tearing the tissues and resulting in imperfect extension. The submucosa was thinner in body tissue than in cardia and antrum tissues. Stretching to 3.0 cm induced a consistent decrease in submucosal thickness (30-70%). The change in thickness varied widely between individual samples. Conclusions: A resection margin of 500μm might be insufficient for the complete removal of malignancy. Moreover, the thickness of the submucosal layer differs with the gastric site and between individuals. Future studies are needed to confirm the findings in human tissue.
