Is superselective embolization of the brain AVMs, the possibilities of adjacent normal brain tissue damage necessitates preembolic evaluation. The authors performed the Sodium Amytal test on 15 patients with brain AVMs. In the AVM patients with negative Amytal test(30 cases), all patients showed normal pattern on EEG and neurologic examinations after embolization Among the five patients with positive Amytal test, three cases showed neurologic deficit and the others two didn't. In eleven patients. Repeated embolization without the Amytal test were done. Among them, 5 cases showed neurlogic deficit and the others were quite normal. In conclusion, the Amytal test is a useful method of evaluation of the risk to damage normal brain tissue which are supplied by superselected feeding vessels. Combining the EEG with this test is a sensitive and objective method in evaluating patients following the Amytal test. And it is essential to performed the Amytal test for repeat embolization procedures.

PURPOSE: This study attempted to investigate the frequency, duration, and risk factors of antibiotic-associated diarrhea (AAD) in infants hospitalized due to febrile urinary tract infection (UTI). This is a basic research on the probiotics used in the prevention and treatment of AAD in infants. METHODS: Medical records of the infants aged 3-6 months hospitalized in Gachon University Gil Hospital from January 2008 to September 2010 due to the febrile UTI were retrospectively reviewed. The episodes of loose or watery stool were investigated for frequency, onset, and duration. Those who had AAD and those who did not (non-AAD) were compared. The antibiotic regimens and the episodes of diarrhea were investigated in AAD group. RESULTS: Total 147 infants were included. Fifty-four (36.7%) showed AAD. Intravenous third-generation cephalosporin (3rd CS) single therapy was used for 102 patients (69.4%), the 3rd CS and non-3rd CS combination therapy for 24 (16.3%), and non-3rd CS combination therapy for 21 (14.3%). There was no significant difference in the dose of cefotaxime between AAD and non-AAD group (P=0.601). According to the antibiotic therapies above, in AAD group, there was no significant difference in the onset and duration of diarrhea respectively (P=0.717, P=0.830). Although the frequency of diarrhea was higher for the 3rd CS and non-3rd CS combination therapy subgroup with 9.25+/-5.30 times/day than the other two subgroups (7.58+/-2.97 times/day in 3rd CS single therapy subgroup, 6.75+/-4.40 times/day in non-3rd CS combination therapy subgroup), there was no statistical significance (P=0.078). CONCLUSION: AAD seems common to the infants aged 3-6 months with febrile UTI, regardless of regimen and amount of antibiotics in usual dosage. Further research on the effects of probiotics used in the prevention and treatment of AAD in infants is warranted.

BACKGROUND AND AIMS: Ectopic pancreas in the stomach is a relatively uncommon abnormality. Although its typical finding on endoscopy was described as a submucosal nodule with central umbilication, it is still difficult to differenciate ectopic pancreas from other pathologies. So we investigated the endoscopic findings of ectopic pancreas in the stomach. METHODS: Between Jan. 1987 and Aug. 1998, nineteen patients who underwent gastroendoscopy and were histologically diagnosed as ectopic pancreas by various methods, were encountered at the Department of Internal Medicine, Severance Hospital, Yonsei University. The clinicopathologic records of all the patients were reviewed. RESULTS: The mean age of the patients was 39.3 years old with a male to female ratio of 1:2.8. Endoscopically, seventeen cases (89.5%) were suggestive of submucosal tumors. Submucosal tumors combined with umbilication were in 4 cases (21.1%), with ulceration in 2 cases (10.5%), erosion in 5 cases (26.3%), ulceration and erosion in 1 case (5.3%), and normal mucosa in 5 cases (26.3%) respectively. The size of ectopic pancreas was in the range of 0.8-3.0 cm, except in one case which measured 6.0 cm. The location of ectopic pancreas was in the antrum in 18 cases (94.7%), and in the angle in 1 case (5.3%). The endoscopic diagnoses were ectopic pancreas in 5 cases (26.3%), submucosal tumor in 12 cases (63.1%), gastric polyp in 2 cases (10.5%). The methods of histologic diagnosis of ectopic pancreas in 3 cases (15.8%) was by endoscopic biopsy, by endoscopic submucosal resection in 10 cases (52.6%), and by operation in 6 cases (31.6%). CONCLUSIONS: Ectopic pancreas in the stomach is found in various morphology, presented as submucosal tumors in the antrum. Because histological diagnosis by endoscopic forcep biopsy is difficult in many cases, endoscopic submucosal resection or operation should be considered.

BACKGROUND/AIMS: Endoscopic ultrasonography (EUS) has been useful in evaluating submucosal lesions of the upper gastrointestinal tract as well as providing guidelines for therapeutic plans. Large proportions of submucosal tumors are diagnosed as stromal tumors. Most are benign, but a significant proportion of them could be malignant. There are a few reports concerning EUS findings as being predictive of malignancy. The aim of this study was to evaluate specific EUS features favoring malignancy in stromal tumors of the UGI tract. METHODS: From January, 1992 to June, 1997, thirty-three cases appeared involving stromal tumors (18 benign, 15 malignant (including 8 STUMP)), and were either surgically (27 cases) or endoscopically (6 cases) resected. Videotapes and photographs were reviewed and EUS features that favored the malignancy were analyzed.

BACKGROUND/AIMS: Intraductal papillary mucinous neoplasm (IPMN) of the pancreas has a favorable prognosis, but seems to be associated with a high incidence of extrapancreatic tumors. The purpose of this study was to evaluate the incidence and clinicopathological features of extrapancreatic tumors associated with IPMN. METHODS: Thirty-seven patients with IPMN of the pancreas, confirmed by surgical resection and typical findings of endoscopic ultrasonography and CT imaging between October 1, 1998 and August 31, 2006 were included. Seventeen patients were diagnosed with surgical resection and biopsy, and others by typical imaging findings of IPMN. These patients were examined for the development of extrapancreatic tumors. RESULTS: Of 37 patients with IPMN, 14 (38%) had 18 extrapancreatic tumors, and 10 (27%) had 13 extrapancreatic malignancies. Five, six, and two extrapancreatic malignancies had diagnosed before during, and after the diagnosis of IPMN. Gastric adenocarcinoma (3 patients, 23%) and colorectal carcinoma (3 patients, 23%) were the most common neoplasms. Other extrapancreatic tumors included lung cancer (n=2), prostatic cancer (n=1), renal cell carcinoma (n=1), cholangiocelluar carcinoma (n=1), urinary bladder cancer (n=1), and gallbladder cancer (n=1), respectively. As benign tumor, there were two gallbladder adenoma, one gastric adenoma, one colonic adenoma and one benign ovarian cystic neoplasm, respectively. CONCLUSIONS: IPMN is associated with high incidence of extrapancreatic tumors, particularly gastric and colorectal neoplasms. Upper gastrointestinal endoscopy and colonoscopy should be done, and systemic surveillance for the possible occurrence of other tumors may allow early detection of extrapancreatic tumor in patients with IPMN.

To quantitively evaluate the initiation failure in Parkinson's disease (PD), we studied the initiation time by using the Cybex isokinetic test machine. Eighteen patients with idiopathic PD and age-matched normal controls were selected, and the initiation time during the extension and flexion of elbow and knee joints were measured in each group. Compared to the normal subjects and the patients with PD, the patients revealed prolongation of initiation time. So, it is suggested that the quantitive measurement of initiation time by Cybex isokinetic test could be a useful clinical tool in evaluating the symptoms of initiation failure of PD.

BACKGROUND/AIMS: The blended current is usually used for endoscopic sphincterotomy (EST) to minimize bleeding. The pure cutting current may induce less edema of the ampulla and therefore result in less injury to the pancreas theoretically. The aim of this study was to evaluate effects of electric currents used on the development of serum pancreatic enzyme evaluation, clinical pancreatitis or bleeding after EST. METHODS: One hundred and eighteen consecutive patients who underwent EST with standard papillotome alone for the treatment of choledocholithiasis were reviewed. All EST had been performed by two endoscopists whose experience on EST was similar: one uses 'blended current' (BC group, n=74), while the other uses 'pure cutting current' (PC group, n=44). RESULTS: Baseline clinical, laboratory, and procedural parameters were similar in both groups. The incidences of hyperamylasemia and hyperlipasemia were similar between two groups. There was no significant difference in the incidence of clinical pancreatitis between two groups (BC 6.8% vs PC 0.0%, p=0.1557). All episodes of pancreatitis were mild. No episodes of significant bleeding occurred after EST. The incidences of sepsis, cholangitis and perforation were also not different between two groups. CONCLUSIONS: Development of complications after standard EST such as hyperamylasemia, clinical pancreatitis, and bleeding may not depend on the electric current used.

PURPOSE: The severity of non-alcoholic fatty liver disease (NAFLD) in type 2 diabetes mellitus (T2DM) population compared with that in normal glucose tolerance (NGT) individuals has not yet been quantitatively assessed. We investigated the prevalence and the severity of NAFLD in a T2DM population using controlled attenuation parameter (CAP). MATERIALS AND METHODS: Subjects who underwent testing for biomarkers related to T2DM and CAP using Fibroscan® during a regular health check-up were enrolled. CAP values of 250 dB/m and 300 dB/m were selected as the cutoffs for the presence of NAFLD and for moderate to severe NAFLD, respectively. Biomarkers related to T2DM included fasting glucose/insulin, fasting C-peptide, hemoglobin A1c (HbA1c), glycoalbumin, and homeostasis model assessment of insulin resistance of insulin resistance (HOMA-IR). RESULTS: Among 340 study participants (T2DM, n=66; pre-diabetes, n=202; NGT, n=72), the proportion of subjects with NAFLD increased according to the glucose tolerance status (31.9% in NGT; 47.0% in pre-diabetes; 57.6% in T2DM). The median CAP value was significantly higher in subjects with T2DM (265 dB/m) than in those with pre-diabetes (245 dB/m) or NGT (231 dB/m) (all p<0.05). Logistic regression analysis showed that subjects with moderate to severe NAFLD had a 2.8-fold (odds ratio) higher risk of having T2DM than those without NAFLD (p=0.02; 95% confidence interval, 1.21-6.64), and positive correlations between the CAP value and HOMA-IR (ρ=0.407) or fasting C-peptide (ρ=0.402) were demonstrated. CONCLUSION: Subjects with T2DM had a higher prevalence of severe NAFLD than those with NGT. Increased hepatic steatosis was significantly associated with the presence of T2DM, and insulin resistance induced by hepatic fat may be an important mechanistic connection.
