The foreign bodies in the upper GI tract are produced chiefly by accidental swallowing and rarely produce symptoms. But it is recommended to remove the foreign bodies if they produce symptoms or retained in GI tract for long duration, and if they have the possibilities of producing complications. Nowadays the development of therapeutic endoscopy enables the removal of the foreign bodies easily. We have reviewed 88 cases of foreign bodies diagnosed by endoscopy from January, 1980 to July 1990 and had the following results. 1) The most common foreign bodies were coins and bezoars, common with the ages under 10 years and over 50 years. 2) The foreign bodies were found in the upper gastrointestinal tract in the order of stomach, esophagus and duodenum. 3) The esophageal stricture especially by lye was the most common underlying cause of upper gastrointestinal foreign bodies. 4) The symptoms and complications were more common with esophageal foreign bodies. 5) By therapeutic endoscopy, the success rate for removal of foreign bodies was 98%.

OBJECTIVE: Thyroid nodule is frequent and occurs in about 5+ACU- of the general population. In contrast, thyroid cancer is much less frequent and occurs in about 5-10+ACU- of thyroid nodules. Distinguishing between benign and malignant lesions is an important task that is best accomplished by fine needle aspiration. Recently, Chiappetta et al. reported that the expression of the high mobility group (HMG) I(Y) proteins correlates with the malignant phenotype of human thyroid neoplasia, and suggested that the detection of the HMG I(Y) proteins might be a valid tool for an easy and sensitive discrimination assay between benign and malignant neoplastic thyroid disease. METHODS: We evaluated the expression of the HMG I(Y) mRNA in 39 frozen thyroid tissues from patients with thyroid nodule by semiquantitative RT-PCR. RESULTS: The expression of the HMG I(Y) mRNA was low in all of 10 normal thyroid tissues. In all of 3 adenomatous goiters, 6 follicular adenomas and 2 Hurthle cell adenomas, the HMG I(Y) mRNA expression level was low. In 11 of 13 papillary carcinomas and all of 5 follicular carcinomas, the HMG I(Y) mRNA expression level was high. CONCLUSION: These results indicate that there is a correlation between the expression of HMG I(Y) and the malignant phenotype of thyroid cancer, suggesting that these proteins may be useful as a marker in thyroid cancer.

Cancer of the gastric stump, first described by Balfour in 1922, is defined as the cancer detected more than 5 years after surgery for a benign disease. We experienced a case of cancer found at the gastric stump after gastrojejunostomy in a 53 years old male patients, proven pathologically as a early cancer. He visited to our hospital with the chief complaint of epigastric pain and indigestion for 1 Months. On past history, he has been received gastrojejunostomy due to duodenal ulcer obstruction, 23 years ago, Gastrofiberscopy was done, and we could find the early gastric cancer lesions at the anterior wall of gastric angle as type Ilc+III and antrum as type IIa. The microscopic finding of the multiple endoscopic biopsies at the gastic angle and antrum revealed the adenocarcinoma of signet ring cell type infiltrated to the level of submucosa. And so, we could diagnose these lesions as a early gastric cancer in the gastric stump after gastrojejunostomy. He was treated with subtotal gastrectomy and discharged with cured condition. Therefore, we report this case with a literature review.

Background and objectives: Carvedilol is a cardiovascular drug, beta- and alpha1-adrenoceptor antagonist, currently approved for the treatment of hypertension, angina, congestive heart failure by FDA. Carvedilol has been shown to attenuate oxygen free radical-initiated lipid peroxidation and to inhibit neointimal formation of aorta following vascular injury by balloon angioplasty. We have investigated the effect of carvedilol on DNA synthesis of vascular smooth muscle cells (VSMC) stimulated by platelet-derived growth factor (PDGF)-BB. MATERIALS AND METHOD: Rat aortic smooth muscle cells were obtained by the combined collagenase and elastase methods. Cells between the 4th and 8th passages were used for the experiments. Incorporated radioactivity of [3H]-thymidine was measured by liquid scintillation spectrometry. RESULTS: PDGF-BB (1 nM) increased [3H]-thymidine incorporation about 70-100% over basal value in cultured VSMC. PDGF-stimulated increase in DNA synthesis was significantly suppressed by simultaneous administration of carvedilol. In contrast, propranolol did not significantly affect 3[H]-thymidine uptake in rat aortic VSMC. CONCLUSION: The present study demonstrate that carvedilol significantly inhibits the proliferation of vascular smooth muscle cell in our condition. These results indicate that carvedilol may be effective in the treatment of cardiovascular diseases principally associated with abnormal vascular smooth muscle growth.

BACKGROUND/AIMS: Endoscopic mucosal resection (EMR) has been known as a method of local treatment for early gastric cancer (EGC) or gastric adenoma. The purpose of this study was to identify the factors affecting complete resection rate (CRR) of EMR and to identify histological discrepancy between endoscopic biopsy and the resected specimen obtained by EMR. METHODS: Forty four gastric adenomas and twenty seven EGCs in 63 patients were treated by EMR from January, 1999 until August, 2002. We analysed the factors affecting CRR on the basis of location, macroscopic type, size, piecemeal resection, and EMR methods. RESULTS: The CRR in antrum was 72%. The CRR of the method using endoscopic resection with hypertonic saline-epinephrine solution, injection, precutting and snaring (ER-HSE) was 78%. The CRR according to en bloc resection was 77%. Sixty six percents of histological coincidence was noted between the endoscopic biopsy and the resected specimen of gastric adenoma. CONCLUSIONS: In this study, the CRR of the ER-HSE method and the lesion located in antrum is higher than that other groups. Gastric adenoma should be removed by EMR because of histologic discrepancy between the endoscopic biopsy and the resected specimen.

Tuberculous colitis, an important extra-pulmonary tuberculosis, is still prevalent in the developing countries and has been resurging in the Western world. The duration and dose of anti-tuberculous therapy have not yet been clarified in the tuberculous colitis. We experienced a case of tuberculous colitis, which relapsed after 9 months of therapy. A 28-year-old man presented with hematochezia and was diagnosed as tuberculous colitis on the basis of colonoscopic findings. He was treated with anti-tuberculous agents for 9 months successfully. Three months later, however, he complained of hematochezia again, suggesting the relapse of tuberculous colitis. He had taken anti-tuberculous therapy for another 15 months and showed no evidence of relapse. Although anti-tuberculous therapy is efficient for tuberculous colitis, rare cases of reactivation should be reminded.

It is well known that newborns and pregnant women typically show higher rates of Streptococcus agalactiae infection. However, the incidence of group B streptococcal (GBS) disease in nonpregnant adults is increasing, particularly in elderly persons and those with significant underlying diseases, such as diabetes, neurologic impairment, and cirrhosis. Skin infections, osteoarticular infections, and pneumonia are commonly associated with GBS, while meningitis and endocarditis are less common. S. agalactiae endocarditis is an uncommon but important condition with a high mortality rate. Several cases of endocarditis due to S. agalactiae have been reported in the literature, but there have been no reports of S. agalactiae meningitis associated with endocarditis in Korea. Here, we describe a case of S. agalactiae meningitis and endocarditis in a 50-year-old man who was successfully treated with intravenous antibiotics and cardiac surgery.
