RESUMO
BACKGROUND/AIMS: Acute hepatitis A (HAV) is markedly increasing recently on. Some patients with acute hepatitis A show severe clinical course. The seroprevalence rate of IgG anti-HAV has been changing with the regions and the times. Vaccination and seroconversion rate of HAV are not well known. In this study, we aimed to study the difference of seroprevalence rate of IgG anti-HAV according to various clinical factors and to know the vaccination rate and seroconversion rate below 10 years old in the central region of South Korea including Cheonan city. METHODS: Seven hundred seventy two subjects were included in the study from January to September 2009. We analyzed seroprevalence rate of IgG anti-HAV according to sex, age, region, and other viral markers. We interviewed the history of vaccination(1st, 2nd) and analyzed seroconversion rate according to vaccination time below 10 years old. RESULTS: The total seroprevalence rate of IgG anti-HAV was 65.3%. The seroprevalence rate of IgG anti-HAV rate in 2nd, 3rd, and 4th decade was very low (1.9%, 18.8%, 44.8%). The vaccination rate of children was about 50%. The seroconversion rate after 1st, and 2nd vaccination were 85%, 96%. CONCLUSIONS: Catch-up vaccination for teenagers and young adults is needed. Immunizing children with HAV vaccine as a routine schedule should be considered.

Bezoars are collections or concretions of indigestible foreign material that accumulate and coalesce in the gastrointestinal tract. Treatment options include dissolution with enzymes, endoscopic removal or aspiration, and surgery. The outcome differs according to the treatment method. A 57-year-old man was admitted with a 1-month history of epigastric pain. On gastrofiberscopy, an approximately 2-cm deep ulcer was seen on the lesser curvature of the antrum and three huge bezoars were found. In order to remove the first one, we injected Coca-Cola into it directly. It took 20 minutes to cut up and 1 hour to remove completely. To decrease the procedure time, we changed the injection fluid to urokinase for the remaining two bezoars. It took 9 and 10 minutes to cut up the second and third bezoars, respectively, and 1 hour to remove them completely. We report a case of phytobezoars treated successfully by endoscopic injections of Coca-Cola and urokinase.
