Background/Aims; The transmission mode of Helicobaeter pylori infection has not been definded. We investigated the seroprevalence of H. pylori infection in spouses of infected patients to clarify the transmission mode of H. pylori infection, Methods: Sera were collected from 26 spouses of infected patients and examined for H. pylori infection by serology. We compared the antibody responses to H. pylori proteins (CagA, VacA and urease subunits) in 5 couples. Results: H. pylori infection was observed in 20 out of 26 spouses (77%). The infection rate was increased from 50% in less than 10 years of cohabitation to 100% in more than 31 years of cohabitation. The gastroscopic exarnination for the infected patients revealed chronic gastritis in 6, gastric ulcer in 9, duodenal ulcer in 8, concurrent gastric and duodenal ulcer in 2, and gastric cancer in 1. In spouses, the gastroscopy showed chronic gastritis in 10 and pyloric canal ulcer with H. pylori infection in 1. The couple with pyloric canal ulcer showed similar antibody responses to CagA, VacA and urease subunits. Conclusions: This study suggested that H. pylori might be transmitted via oral to oral route. Further study about the risk of gastroduodenal lesion in spouses is needed.
Most intussusceptions occur in children under 1 year of age whereas 5%∼10% occurs in adults. Although intussusception has an acute occurrence in children, symptoms in adults may be subacute or chronic, and the diagnosis is often delayed. In contrast to adults, intussusception in children is the most common cause of intestinal obstruction, and one of the most frequent causes of surgical emergencies. While idiopathic cases account for more than 90% of those seen in children, many cases in adults are generally related to neoplasm. However, intussusception due to a primary malignant lymphoma of the small intestine is a rare clinical condition. There is little information on the role of colonoscopy in colonic intussusception. Two cases are herein reported, of malignant lymphoma in the ileocecal region causing intussusceptions in which the diagnosis and reduction of intussusception were made by colonoscopy. Colonoscopy plays a useful role in the diagnosis and management of intussusception. The clinical, radiographc, endoscopic, and pathologic findings are described with brief reviews of related literature.
We analyzed 166 patients with hepatocellular carcinoma (HCC) retrospectively for 3 years duration. The diagnosis was made by serologically, histologically and/or radiologically. They were 136 males and 30 females and ages ranged from 31 to 80 (mean: 56) years with a peak incidence during the sixth decade. Serum AST was normal in 39 (23%) and ALT in 113 (68%). In 20% of the patients, AST/ALT was greater than 3:1. Serum HB was positive in 110 patients (66%), anti HCV in 26 (16%), and no viral markers were dectected in 30 (18%). Among 110 HBsAg positive patients, 30 (27%) were positive for HBeAg and 34 (31%) were positive for HBV-DNA. Of the 30 patients who were both HBsAg and anti-HCV negative, evidence of past HBV infection (anti-HBs or anti-HBc) was found in 12. Using the polymerized chain reaction (PCR), HBxAg was detected in 90 (74%) of 122 patients studied: 71/82 (87%) in HBsAg positive, and 19/40 (48%) in HBsAg negative. The anti-HCV or HCV-RNA was detected in 8 (17%) ef 48 patients who were positive for HBsAg and in 18 (56%) of 32 patients who were neagtive. Liver cirrhosis was found in 148 patients (89%) when they initially came to the hospital. Portal vein thrombosis was noted in 63 patients (38%) by ultrasonography and/ or angiographically. Serum alpha fetoprotein (AFP) was elevated (greater than 400 ng/dl) in 9(60%). No correlation was found between the level of AFP and the extent of the tumor. Among 166 patients, small tumor (less than 5 cm in diameter) was found in 17 of whom surgical resection was done in 3, and 11 reeived transarterial embolization (TAE) and/or percutaneous ethanol injection (PEI). In conclusion, most of the patients with. HCC were complicated with decompensated liver cirrhosis when they initially came to the hospital. Therefore, it is absolutely recommended to perform the serial alpha fetoprotein measurement and ultrasonographic examination regularly to all the patients with chronic hepatitis regardless of the etiology of the liver disease.
Background/Aims: Extrahepatic bile duct(EHBD) carcinoma is a rare tumor among the population of the world and accounts for less than 2% of cancers found at autopsy and about 10% of all biliary duct cancer. To identify the clinical characteristics associated with prognosis and the survival rate by treatment modalities, we reviewed 120 patients with extrahepatic bile duct carcinoma who were diagnosed at the Kangdong Sacred Heart Hospital of Hallym University from June 1987 to October l994. Methods: According to treatment modalities, these patients were divided into 50 cases of the operation group, 47 cases of the non-operative treatrnent group and 23 cases of the no treatment group. The survival rate of these three groups was analyzed according to Cutler-Ederer methods. Results: The most common symptom and sign were jaundice(85.8%) and hepatomegaly (57.5%). The most common site of tumor was the common hile duct(63.3%), followed by the hepatic duct bifurcation(25.8%), the common hepatic duct(9.2%), the cystic duct(0.8%) and tbe diffuse type(0.8%). The median survival was l0.7 months. The survival rate was 76.7% in 3 months, 68.4% in 6 months, 4l.6% in l year, 14.1% in 2 years, and 3.4% in 5 years. According to the treatment modalities, the median survival was 16.3 months in the operation group, 6.3 months in the non-operative treatment group, and 3.5 rnonths in no treatment group. Conclusions: The operation group had a better survival rate than the other group. We conclude that operation offers the best prognosis. The result of this study suggests that early diagnosis and operation prolong survival in these patients. Further studies of adjuvant chernotberapy and radiotapy wi]l be necessary to improve patients survival.
