OBJECTIVE: The results for finding the deficit in the anterior cingulate (ACC) in schizophrenic patients (SZ) have been inconsistent according to the studies that used different Stroop tasks, which is unlike the deficit in the dorsolateral prefrontal cortex (DLPFC). In order to explore for the core region that's responsible for the selective attention deficit in SZ, we examined the results of a functional neuroimaging study, which involved the performance of the Stroop task using high or low prefrontal cortex related loads in SZ. METHODS: Ten schizophrenic patients and healthy controls (HC) received functional magnetic resonance imaging (fMRI) during a Short/Long-term latency Stroop task. The changes in the neural activity were determined in well-known Stroop related regions of interest (ROIs) that consisted of the DLPFC, ACC, the parietal lobule and in the whole brain regions for both the main and interaction effects of latency, and the results of the short-term and long-term latency Stroop conditions were compared. RESULTS: The response times for both the congruency and latency effects were more prolonged in the schizophrenics than in the HC. For the congruency effect, the schizophrenics showed significantly less activation in the same site of the left DLPFC in both the short-term and long-term latency conditions, as compared with the HC. For the latency effect, the regions of the left-side language network were over- or under-activated in the schizophrenics, as compared with the HC. Any interaction effect was not found for both the behavioral and fMRI results. CONCLUSION: Our results indicate that the deficit in the left DLPFC is the core impairment of attentional processing in schizophrenics, regardless of other possible interactions such as the latency effect.

PURPOSE: To report a case of bilateral acute myopia and angle-closure with ciliochoroidal detachment in Vogt-Koyanagi-Harada (VKH) syndrome. CASE SUMMARY: A 43-year-old Korean woman diagnosed with VKH syndrome underwent intravenous methylprednisolone steroid pulse treatment. After oral medication was given for 2 days, the anterior chambers became shallow in both eyes. Intraocular pressure (IOP) increased to 25 mm Hg in the right eye and 23 mm Hg in the left eye. Subretinal fluid increased and visual acuity decreased with myopic shift in both eyes. IOP did not decrease despite maximum tolerated medical therapy. Ultrasound biomicroscopy (UBM) revealed that ciliochoroidal effusion caused forward displacement of the lens-iris diaphragm, which resulted in anterior chamber shallowing and angle closure in both eyes. The patient was treated with cycloplegic eyedrops and intravenous steroid pulse therapy. After intravenous steroid pulse treatment was given for 2 days, the anterior chambers became deep in both eyes. IOP reduced to 13 mm Hg and 14 mm Hg in the right and left eye respectively. Visual acuity increased with normalization of myopic shift. UBM revealed that the ciliochoroidal effusion had resolved in both eyes.

In patients with hepatocellular carcinoma (HCC) or liver cirrhosis (LC) accompanied by hepatitis E virus (HEV) infection, hepatic failure often leads to debility. Here, we report about a 63-year-old man with alcoholic LC who was referred to our hospital with jaundice and abdominal distension 10 days earlier. Abdominal computed tomography showed necrotic HCC accompanied by left lobe shrinkage without tumor progression. Laboratory and imaging findings revealed no acute infection focus. The patient reported no herbal medicine or alcohol consumption, and there was no evidence of acute viral hepatitis. One month later, HEV immunoglobulin M positivity was confirmed, and deterioration of liver function due to HEV infection was suspected. The patient often ate raw oysters and sashimi, as well as boar meat, which is a well-known risk food for HEV infection. His umbilical hernia deteriorated due to tense ascites and infection by skin abrasion. The patient progressed to hepatorenal syndrome and eventually died. Liver function preservation is important when treating HCC patients. Therefore, clinicians should pay more attention to the prevention of HEV and others causes of direct liver injury.

35 cases of Mallory-Weiss syndrome among 277 cases of upper gastrointestinal bleeding were ascertained by endoscopy at department of internal medicine St. Columban's hospital. The mean age was 41.6 years. All of 35 cases were found in male. Combined disease were gastritis(15 cases), peptic ulcer(7 cases) and esophageal varix(3 cases). The most common precipitating factor was vomiting, 22 cases among the 28 cases of vomiting(80%) developed after drinking. Endoscopic finding revealed active bleeding in 5 cases, blood clot without active bleeding in 22 cases, and scar change without bleeding evidence in 8 cases. Most cases had had hematemesis after active bleeding but 5 cases had had only melena without hematemesis. The Mallory-Weiss lacerations were located at stomach in 16 cases(46%), at esophagogastric junction in 11 cases(31%) and at esophagus in 8 cases. On the view of gastric direction, 14 cases were on anterior wall side, 9 cases were on posterior wall side, 11 cases were on lesser curvature side and one case was on great curvature side. Single lacerations were more common than multiple lacerations.

Bezoars are persistent concretions of indigestible matter, usually seen in the stomach. But very rarely have bezoars been reported in the esophagus.. Most esophageal bezoars are either phytobezoars or medication bezoars occuring usually in the middle aged & elderly associated with underlying anatomical or functional abnormalities of esophagus. A variety of techniques has been developed recently in diagnostic and therapeutic endoscopy. So endoscopic management is safe and successful in most cases those required surgical management. We experienced an esophageal bezoar consisted with esophageal candidiasis in a patient who underwent esophago-gastric anastomosis and proximal gastrectomy due to early gastric cancer. The bezoar was removed by endoscopy and the esophago-gastric stenosis was treated with balloon dilator without any significant complication.

PURPOSE: To determine the prevalence and correlates of nocturia in Korean community-dwelling older men. MATERIALS AND METHODS: A study population of 439 Korean elderly men (> or =65 years of age, including 299 men from a randomly sampled population) was sampled from residents of Seongnam, Korea. Standardized face-to-face interviews and questionnaires were performed. In-person interviews solicited sociodemographic information, medical history, Mini-Mental State Examination (MMSE) score, and measurement of body mass index. Transrectal ultrasonography and laboratory tests including urinalysis and measurement of creatinine and prostate-specific antigen were performed. For the analysis of prevalence, 299 randomly sampled men were included. Men who answered the International Prostate Symptom Score questionnaire (n=424) were included in the analysis of the correlates of nocturia. Nocturia was defined as having to get up to urinate two or more times per night (> or =2). RESULTS: The overall prevalence of nocturia was 56.0% for community-dwelling older men. There was a significant correlation between age and the prevalence of nocturia (p<0.001). The univariate analysis revealed a significant association between nocturia and MMSE score (odds ratio [OR], 0.88; p<0.001), history of benign prostatic hyperplasia (BPH) (OR, 2.85; p=0.003), alpha-blocker usage (OR, 2.79; p=0.018), alcohol consumption (OR, 0.65; p=0.035), and smoking (OR, 0.58; p=0.025). Age, duration of education, MMSE score, and prostate volume were also significantly associated with nocturia. In the multivariate regression analysis using forward elimination, nocturia was significantly associated with a history of BPH and MMSE score. CONCLUSIONS: The prevalence of nocturia was 56.0% in Korean community-dwelling older men. Nocturia was associated with age and a history of BPH. MMSE score was protective.

BACKGROUND: There are numerous therapeutic options for molluscum contagiosum (MC) and these may be broadly subdivided into surgical procedures (curettage, squezzing), chemical application (silver nitrate, cantharidin) and immunological therapies (imiquimod). However, in young children it is quite difficult to treat the condition due to pain associated with these procedures. Therefore, physicians need to consider more tolerable treatment options in pediatric patients. OBJECTIVE: We evaluated 20 children with MC for clinical effectiveness and side effects of imiquimod application. METHODS: Twenty children with MC were asked to apply 5% imiquimod cream three times per week at nights every other day for between 8~12 weeks. RESULTS: Nine of the 20 patients (45%) achieved complete clearance after a mean treatment period of 6.9 weeks. Partial clearance was observed in 10 patients (50%) and no response in 1 patient (5%). No patients dropped out due to adverse effects. Twelve children (60%) reported erythema and five children (25%) reported itching. CONCLUSION: Therapy with imiquimod cream was found to be effective, safe and painless in the treatment of MC in children. However, large-scale, double-blind, controlled prospective studies are needed to confirm the effectivenss of Imiquimod cream.

Fetomaternal hemorrhage is very common and the commonest cause of anernia in the newborn. But, few blood cells enter the maternal circulation in most pregnancies. Occasionally large intrauterine bleeding results in severe fetal and neonatal anemia, shock, and rarely death. To identify the fetal blood in the maternal circu1ation, acid elution technique of Kleihauer-Betke test is usually used. And imrnedate neonatal blood transfusion should be done for good prognosis. We report a case of massive feto-maternal hemorrhage (>100 ml) in a preterm neonate with severe anemia at birth, which was diagnosed by Kleihauer-Betke test and was treated with blood transfusion.

BACKGROUND: Laparoscopic cholecystectomy has become the gold-tandard treatment for symptomatic gallbladder diseases. The evaluation and the treatment of common duct pathology is an essential component in the surgical management of biliary tract disease. The purpose of the present study was to identify the value and the importance of laparoscopic cholangiography compared to endoscopic retrograde cholangiography (ERC) in a laparoscopic cholecystectomy and to suggest the role of laparoscopic cholangiography in the management of patients undergoing laparoscopic cholecystectomy. METHODS: A laparoscopic cholecystectomy was attempted in two hundred six consecutive patients treated at Hallym University between January 1993 and December 1996. Patients were divided into three groups: In group I, 167 patients were examined with preoperative ERC while in group II, 17 patients were examined with laparoscopic cholangiography; Group III included 22 patients who were not examined with preoperative ERC or laparoscopic cholangiography. RESULTS: The average age was 52.78 years in group I, 45.62 years in group II, and 49.22 years in group III. The average operative time was 76.88 minutes in group I, 131.47 minutes in group II, and 85.22 minutes in group III. The operative time in group II was longer than that in group I (p<0.001). The duration of postoperative hospitalization was 4.9 days in group I and 4.11 days in group II, but this difference was not statistically significant (p=0.166). Conversion to an open cholecystectomy was 17/167 (10%) in group I, 1/17 (5%) in group II and 5/22 (22%). No complications or deaths occurred that were due to laparoscopic cholangiography. The postoperative complications in group I/II/III included bile leakage (3/0/2), bleeding in the bed of the gallbladder (5/0/0), wound bleeding (2/1/1), recurrent common duct stones (2/0/0), subcutaneous emphysema (4/1/0), shoulder pain (12/3/0), and wound infections (15/2/1). CONCLUSIONS: Although cholangiography may not be indicated for all patients undergoing a laparoscopic cholecystectomy, it will eventually be required. We conclude that laparoscopic cholangiography, as well as ERC, is a good method for evaluating the biliary tree. Laparoscopic cholangiography is clinically useful in patients who have negative ultrasonography and a dilated bile duct. Also, laparoscopic cholangiography has many advantages, especially at a teaching hospital: it outlines the anatomy of the extrahepatic biliary tree, identifies anomalies of surgical importance in time before iatrogenic damage is inflicted, detects stones in the cystic duct, discovers unsuspected stones, and develops experience with the technique. However, it is technically diffult to cannulate cystic duct and extends the operating time.
