M$\acute{e}$n$\acute{e}$trier's disease is a rare form of acquired gastropathy characterized by giant rugal folds in the stomach and protein-losing gastropathy. Children with M$\acute{e}$n$\acute{e}$trier's disease tend to follow a benign self-limited course with symptoms typically completely resolving within 2 to 10 weeks in contrast to the chronic course in adults. A 9-year-old girl presented with a history of gradually worsening abdominal distension, increasing body weight, and abdominal pain for 2 weeks. Physical examination on admission indicated periorbital swelling, pitting edema in both the legs, and abdominal distension with mild diffuse tenderness and shifting dullness. Laboratory tests on admission showed hypoalbuminemia, hypoproteinemia, and peripheral eosinophilia. The test result for anti-cytomegalovirus immunoglobulin M was negative. Increased fecal alpha 1 anti-trypsin excretion was observed. Radiological findings showed massive ascites and pleural effusion in both the lungs. On gastroscopy, large gastric folds, erythema, erosion, and exudation were noted in the body and fundus of the stomach. Microscopic findings showed infiltration of eosinophils and neutrophils in the gastric mucosa. Her symptoms improved with conservative treatment from day 7 of hospitalization and resolved completely.

Nowadays, gastropathy is a common disease. As endoscopic equipment are developed and used widely, it is possible to provide a large number of endoscopy images. Computer-aided Diagnosis (CADx) systems aim at helping physicians to identify possibly malignant abnormalities more accurately. In this paper, we present a CADx system to detect and classify the abnormalities of gastric lesions which include bleeding, ulcer, neuroendocrine tumor and cancer. We used an Inception module based deep learning model. And we used data augmentation for learning. Our preliminary results demonstrated promising potential for automatically labeled region of interest for endoscopy doctors to focus on abnormal lesions for subsequent targeted biopsy, with Az values of Receiver Operating Characteristic(ROC) curve was 0.83. The proposed CADx system showed reliable performance.

Purpose: Pachydermoperiostosis is a rare hereditary disease characterized by finger clubbing, periosteal reaction, and pachydermia. The underlying pathogenic mechanism of this disease remains unclear. This disease is known to be associated with a variety of diseases such as cranial suture defect, bone marrow failure, hypertrophic gastropathy, Crohn's disease, and female escuchen. Methods: A 50-year-old male had digital clubbing of both hands, coarse hypertrophic skin changes of face, progressive thickening and furrowing on the scalp(cutis verticis gyrata), persistent pain in the limbs and joints. Other cutaneous features include moderate blepharoptosis, pole-like lower legs and feet. Results: We performed surgical excision for hypertrophic skin change of scalp because of frequent eczematous skin change, severe itching sensation and cosmetic problem. Diagnosis is confirmed by bony proliferative periosteal reaction, pathologic findings, and characteristic clinical findings. Conclusion: Pachydermoperiostosis is manifested by finger clubbing, and hypertrophic skin changes causing coarse facial features with thickening and periosteal bone formation. We experienced a case of pachydermoperiostosis. Brief review of related literature is given.

$M\acute{e}n\acute{e}$trier's disease is a rare protein-losing gastropathy characterized by hypertrophic gastric fold, foveolar hyperplasia, and hypoproteinemia with resulting peripheral edema. It is clinically evident as nonspecific gastrointestinal symptoms, including abdominal discomfort, nausea and vomiting, abdominal pain, weight loss, diarrhea, and edema. Pediatric $M\acute{e}n\acute{e}$trier's disease usually has an insidious onset and progressive, chronic clinical course and it spontaneously resolves in weeks or months. The pathogenesis of $M\acute{e}n\acute{e}$trier's disease is not clearly understood. $M\acute{e}n\acute{e}$trier's disease is thought to be associated with some gastric infections. But the cause of $M\acute{e}n\acute{e}$trier's disease is unknown, an association with cytomegalovirus (CMV) and Helicobacter pylori has been suggested. In Korea, We present the first a case of pediatric $M\acute{e}n\acute{e}$trier's disease with positive evidence of CMV and H. pylori.

Protective effect of DA-9601, an extract of Artemisia Herb, against ethanol-induced gastric mucosal injury was evaluated in rats. In the prophylactic study, DA-9601 exhibited total protection (99.4%) against absolute ethanol-induced gastropathy, And the protective effect of DA-9601 lasted up to 2 hours, which was longer than those of other contemporary mucoprotectants. In the treatment study, DA-9601 significantly facilitated the healing of 70% ethanol-induced mucosal damage, which was superior to cetraxate, a commonly used anti-ulcer drug. The mechanisms of mucoprotection of DA-9601 were also assessed. DA-9601 increased the release of prostaglandin E$_2$ from murine neutrophils in a dose-dependent manner in vitro. The cytoprotective effect of DA-9601 against ethanol-induced mucosal damage was significantly diminished by the concommitant injection of N$\omega$-nitro-L-arginine methyl ester (L-NAME, 5 mg/kg, i.v.), a non-specific nitric oxide (NO) synthase inhibitor, while it was not affected by preinjection of indomethacin (5 mg/kg, s.c.), a prostaglandins-depletor. And it was found that DA-9601 significantly enhanced adaptive cytoprotective action of 10% ethanol against absolute ethanol (56.9$\pm$6.5 vs 23.0$\pm$3.3 mm$^2$, p<0.05, mean$\pm$SEM), though its exact underlying mechanism remains to be clarified. The present fin[lings demonstrate that DA-9601 exerts gastroprotecticv actions for the stomach against ethanol through several different underlying mechanisms, in which prostanglandins and NO are involved. In conclusion, the results obtained suggest that DA-9601 can be useful both in prevention and treatment of ethanol-induced gastric damage.

Objectives : This study was carried out to investigate the effects of Soche-hwan extract on indomethacin-induced gastric mucosal lesions of mice. Methods : Experimental mice were divided randomly into four groups. The normal group, the gastropathy group of gastro-inflammation elicited mice, the misoprostol group of mice administered misoprostol after gastro-inflammation elicitation and the Soche-hwan group of mice administered Soche-hwan after gastro-inflammation elicitation. Results : The hemorrhagic erosion of gastric mucosa, the damage of arrangement of mucous secreted cells and HSP70 increased in the gastro-inflammation elicited group, but decreased significantly in the misoprostol and Soche-hwan extract administered groups. Cell proliferation of gastric mucosa decreased in the gastro-inflammation elicited group, but increased significantly in the misoprostol and Soche-hwan extract administered groups. The distribution of mucosal neck cells and mucosal surface cells and PNA positive reactions of surface mucus cells decreased in the gastro-inflammation elicited group, but increased significantly in the misoprostol and Soche-hwan extract administered groups. COX-1 positive cells decreased in the gastro-inflammation elicited group, but increased significantly in the misoprostol and Soche-hwan extract administered groups. iNOS mRNA and COX-2 mRNA increased in the gastro-inflammation elicited group, but decreased significantly in the Soche-hwan extract administered group. NF-kB p65, iNOS and COX-2 increased in the gastro-inflammation elicited group, but decreased significantly in the misoprostol and Soche-hwan extract administered groups. Conclusion : Soche-hwan extract had excellent effects on indomethacin-induced gastric mucosal lesions in mice.

Aim: P53, the most commonly mutated tumor suppressor gene in all types of human cancer, is involved in cell cycle arrest and control of apoptosis. Although p53 contains several polymorphic sites, the codon 72 polymorphism is by far more common. There are divergent reports but many studies suggest p53 pro/pro SNP may be associated with susceptibility to developing various cancers in different regions of the world. The present study aimed to find any correlation between H. pylori infection and progression of carcinogenesis, by studying apoptosis and the p53 gene in gastric biopsies from north Indian population. Materials and Methods: A total of 921 biopsies were collected and tested for prevalence of H. pylori by rapid urease test (RUT), imprint cytology and histology. Apoptosis was studied by the TUNEL method. Analysis of p53 gene polymorphism at codon 72 was accomplished by PCR using restriction enzyme BstU1. Observation: Out of 921 samples tested 56.7% (543) were H. pylori positive by the three techniques. The mean apoptotic index (AI) in the normal group was 2.12, while gastritis had the maximum 4.24 followed by gastric ulcer 2.28, gastropathy 2.22 and duodenal ulcer 2.08. Mean AI in cases with gastric cancer (1.72) was less than the normal group. The analysis of p53 72 SNP revealed that p53 (Arg/Arg), (Pro /Arg) variant are higher (40.59% & 33.66%) as compared to p53 pro/pro variant (25.74%) inthe healthy population. Conclusions: The North Indian population harbors Arg or Pro/Arg SNP that is capable of withstanding stress conditions; this may be the reason of low incidence of gastric disease in spite of high infection with H. pylori. There was no significant association with H. pylori infection and AI. However, there is increased apoptosis in gastritis which may occur independent of H. pylori or p53 polymorphism.
