BACKGROUND: Currently the most common treatment modality of refractory ascites in patients with liver cirrhosis was large volume paracentesis, but this procedure usually needed albumin infusion and occasionally developed unwanted complications. By reason of albumin shortage in Korea and occasional unfavorable complications, we studied the usefulness of dialytic ultrafiltration as an another treatment modality of refractory ascites. METHODS: Dialytic ultrafiltration was done in 10 patients (total 48 times) with liver cirrhosis or hepatocellular carcinoma. Two drainage conduit (via 16 gauge angio-catheter) of input and output were made by puncture of patient's right and left lower quadrant abdomen. The initial ultrafiltration rate of dialyser was 250mL/min. Ascitic fluid was removed continuously until the filtration rate down at 50mL/min. After ultrafiltration, ascitic fluid contained concentrated albumin and large molecules was reinfused via input conduit. Pre-treatment and post-treatment level of blood chemistry, plasma renin concentration, aldosterone, and electrolytes in serum; total protein and albumin in ascites were measured. During the ultrafiltration, we closely observed the change of blood pressure, heart rates and mental status. RESULTS: The mean ultrafiltration time was 231+/-28min, ultrafiltrated volume was 5.15+/-1.41 L. During dialytic ultrafiltration, patient's blood pressure and heart rate were stable and there was no change of mental status. After dialytic ultrafiltration, blood urea nitrogen level significantly decreased from 30.5+/-23.7mg/dL to 25.7+/-20.2mg/dL; serum aldosterone level decreased from 807.3+/-301.1pg/ml to 431.1+/-187.2pg/ml in serum (P<0.01). The albumin level in the ascitic fluid significantly increased from 0.67+/-0.28g/dL to 1.90+/-1.16g/dL (P<0.01). Plasma renin concentration level tend to decreased (P=0.06). The patient's serum total protein, albumin, electrolytes, and creatinine were not changed. Complications of dialytic ultrafiltration were peritonitis (one case) and hypotension (one case). But these unwanted complications were readily managed by adequate antibiotics and intravenous fluid therapy. CONCLUSION: The dialytic ultrafiltration can be used effectively without albumin infusion in the treatment of refrartory ascites in patients with advanced liver cirrhosis.

This study was performed using mealtime atmosphere to characterize the food ecology of Korean children residing in different regions of Korea. A total of 705 elementary school students, 347 girls and 358 boys, were divided into three groups according to the areas where they lived, which included Seoul (n = 230), provincial cities (n = 273) and rural areas (n = 202). The subjects were asked to fill out questionnaires which were categorized to determine various factors related to food ecology, life styles, and health related symptoms. The average age of the study subjects was 11.5 years. The results showed that the average height (p < 0.01), weight (p < 0.01) and body mass index (BMIs)(p < 0.01) of the rural group were significantly lower than those of the Seoul and provincial city groups. A significantly higher proportion (10.4%) of the rural group was from disfunctional families, including single parent families, than those of the Seoul (1.7%) or provincial city (4.4%) groups. However, a larger number of children from Seoul ate alone, did not enjoy their meals, and hardly talked to each other during breakfast time, compared to those from the provincial city or rural areas. Also, the proportion (33.0%) of 'good' in balance of meal was the lowest (33.0%) in Seoul of the three areas (p < 0.01). Most of the children answered that they liked having breakfast and dinner with the whole family. In conclusion, the food ecology of elementary children differed according to the regions in which they resided. Although children from Seoul had higher BMIs, their nutritional intake was not satisfactory, and their undesirable food ecology could be a contributing factor.

Stomatococcus mucilaginosus is a Gram-positive coccus normally found in the oropharynx and upper respiratory tract. Recently, S. mucilaginosus has been increasingly reported to cause seri-ous infections in immunocompromised patients. A 42-year-old male patient with chronic myeloge-nous leukemia developed the clinical signs and symptoms of septicemia in the state of neutropenia due to the failure of a bone marrow transplant. The blood cultures revealed Gram-positive cocci in three sets of aerobic blood culture bottles. The bacteria were identified as S. mucilaginosus by an API STAPH Identification Panel (bioMerieux SA, Marcy 1 'Etoile, France). The patient was cured bacteriologically with a vancomycin treatment for 20 days. Here we report the first case of S. mucilaginosus septicemia in Korea.

PURPOSE: The effective suppression of Kupffer cell function is believed to contribute to the prevention of preservation/ reperfusion injury. In this study, the effect of Gadolinium, a synthetic Kupffer cell suppressor, on the reperfusion injury was examined using a canine partial liver transplant model. METHODS: About 70% of the liver was harvested and reimplanted in a mongrel recipient dog weighing 20~25 kg. Gadolinium Chloride (10 mg/kg) was infused via the cephalic vein 24 hour before harvesting the partial liver (Gadolinium group, n=5). Serum Aspartate Aminotransferase (AST) Alkaline phosphatase (ALP), Lactate dehydrogenase (LDH), and morphological grading of the graft were compared with the control group (n=5). Statistical analysis was done with an independent T-test. RESULTS: The total ischemic time was 4 hours and 27 minutes on average. One hour after reperfusion, there were no significant differences in the AST, ALP and LDH level, and the pathologic scores. At 48 hours after reperfusion, the AST (P=0.03) and LDH (P=0.05) levels were significantly lower in Gadolinium group. CONCLUSION: Kupffer cell blockage using the Gadolinium chloride might be an effective way of reducing ischemia reperfusion injury. However, this effect was not evident in the early stages of reperfusion.

Granular cell tumor is relatively uncommon, it is usually benign and it can be located anywhere throughout the body. It is uncommon in the digestive tract, and especially in the colon and rectum. The endosonographic features of granular cell tumor are usually a relatively hypoechoic, heterogenous lesion in the submucosa, but this tumor has rarely been reported in the colon. We report here on two cases of granular cell tumors of the colon that were observed by using endoscopic ultrasonograpy for making the differential diagnosis of a submucosal tumor and these tumors were confirmed by microscopic examinations after endoscopic mucosal resection.

We report the case of a patient with fulminant myocarditis caused by influenza A virus, who presented with acute-onset heart failure and cardiogenic shock and was treated successfully with single dose of intravenous peramivir and with pharmacologic hemodynamic support. A 45-year-old Korean woman presented to our emergency department (ED) with shortness of breath and an episode of seizure that developed abruptly 5 hours before she arrived in the ED. She had a history of recurrent epileptic seizure 25 years ago, but denied other specific medical illnesses. In the ED, she was hypoxemic (arterial partial pressure of oxygen, 59.8 mmHg on room air) and chest radiography revealed bilateral alveolar infiltrates. A rapid antigen test for influenza A virus was positive, and she was administered a single dose of peramivir (300 mg) intravenously. Five hours later, the patient's dyspnea had worsened and she was hypotensive (blood pressure, 86/53 mmHg), requiring norepinephrine infusion. Further evaluation disclosed an increased cardiac troponin I level of 1.36 ng/mL and a depressed left ventricular ejection fraction of 30%. Under the diagnosis of influenza A-associated myocarditis and cardiogenic shock, she was managed with continuous critical care in the intensive care unit. On day 3, the patient's dyspnea began to resolve and her ventricular function returned to normal. Real-time polymerase chain reaction assays for influenza viruses in serial nasopharyngeal aspirates were positive for influenza A (hH3N2) with a threshold cycle value of 27.39 on day 2, but these became negative by day 4. The patient recovered and was discharged on day 9 after admission. In conclusion, this case indicates that intravenous peramivir might be an effective antiviral agent for the treatment of severe influenza A virus infection.

BACKGROUND/AIMS: A two-year, prospective, nationwide multicenter study was undertaken to evaluate the effect of Helicobacter pylori eradication on the development of reflux esophagitis (RE) and gastroesophageal reflux disease (GERD) symptoms in the Korean population. METHODS: In total, 1,489 subjects without RE were enrolled at the outpatient clinics of 12 tertiary hospitals nationwide, and 452 subjects underwent follow-up (F/U) for 2 years to evaluate the development of RE and GERD symptoms. RESULTS: RE was found in 33 subjects (7.3% of 452 subjects) and 14 subjects (7.3% of 192 subjects) during the first and second year of F/U, respectively. H. pylori status was not associated with the development of RE. RE was found in six (9.0%) of 67 H. pylori-negative patients, in 26 (11.2%) of 233 eradicated subjects and in eight (7.0%) of 114 noneradicated subjects (p=0.532). Multivariate analysis showed that age > or =60 years (odds ratio [OR], 7.11; 95% confidence interval [CI], 1.92 to 26.41), alcohol consumption (OR, 4.43; 95% CI, 1.03 to 19.19) and F/U cholesterol levels > or =200 mg/dL (OR, 5.03; 95% CI, 1.32 to 19.17) were significant risk factors for the development of RE. There was no significant difference in the development of GERD symptoms or weight according to H. pylori status during the 2-year F/U. CONCLUSIONS: Eradication of H. pylori did not affect the development of reflux esophagitis or GERD symptoms among patients in outpatient gastroenterology clinics in South Korea.

The incidence of malignant change of ovarian mature teratoma is 1~2%. The majority is squamous cell cancer, the others was adenocarcinoma. Neuroepithelial tissue was frequently detected in mature cystic teratoma, but their malignant change was extremely rare. Only, two cases of neuroblastoma of ovarian teratoma were reported in the world. We report one case of neuroblastoma arising in ovarian mature teratoma with a brief review. Our case is the third reported one in the world.

PURPOSE: There are a number of reports suggesting that widespread propagation of weeds and high concentration of weed pollen have been contributed to climate change. We investigated the interrelationship between allergenic pollen concentration, allergic symptom and meteorological factor. METHODS: We collected data of pollen concentration and meteorological factors in 7 stations nationwide during between 1998 and 2012. We recruited total 297 allergic patients sensitized to weed pollens from each station, conducted a survey about allergic symptom, and calculated symptom index. We surveyed the vegetation area of ragweed and Japanese hop. Based on these data, we performed the long-term trend analysis (X11-ARIMA, autoregressive integrated moving average) on regional pollen concentration, and correlation analysis to investigate the interrelation between weed pollen concentration, allery symptom index and meteorological factor. We have also done regression analysis on vegetation area and maximal pollen concentration. RESULTS: Long-term trend analysis showed the increasing trend of pllen concentration in Seoul. Weed pollen concentration, allergy symptom index and each meteorological factor were not correlated significantly. Regression analysis revealed that increase of weed vegetation area results in increase of weed pollen concentration. Through this regression equation, we estimated the vegetation area that can product pollen concentration triggering allergenic risk. CONCLUSION: Meteorological factors, pollen concentration and allergic symptoms should be consistently assessed and the relationship between each factor should be analyzed, considering climate change. It is necessary to verify the equation for pollen estimation by vegetation area and set up a policy for vegetation control focused on the reduction of allergenic pollen.
