Infarction in the territory of the posterior choroidal artery(PChA) is rare. The main clinical manifestations of the PCHA infarction are known to be visual field defect, sensory-motor dysfunction, neuropsychological disturbances. Neuropsychological disturbances include of transcortical aphasia and amnesia. The latter disturbance is very rare and reported to be transient. We report a 77 year old man who presented with severe selective amnesia due to PChA infarction. Neurologic examination revealed right homonymous hemianopsia. Brain MRI showed infarction of PChA territory and multiple lacunes in the preventricular deep white matter.

PURPOSE: The purpose of this study is to evaluate the changes of conditional survival (CS) probabilities and to identify the prognostic parameters that significantly affect CS over time post-surgery in upper tract urothelial carcinoma (UTUC) patients. MATERIALS AND METHODS: A total of 330 patients were examined in the final analysis. Primary end point was conditional cancer-specific survival (CSS), overall survival (OS), and intravesical recurrence-free survival (IVRFS) after surgery. The Kaplan-Meier method was used for calculation of CS. Cox regression hazard ratio model was used to determine the predictors of CS. RESULTS: UTUC patients who had already survived 5 years after radical nephroureterectomy had a more favorable CS probability in all given survivorships compared to those with shorter survival times. Patients with unfavorable pathologic features showed a higher increment of 5-year conditional CSS and OS compared to their counterparts. For 5-year conditional CSS, several factors, including high-grade tumor, lymphovascular invasion, and tumor location showed significant association with risk elevation over time. Only age remained as a predictor of 5-year conditional OS with increased risk in all given survivorships. For 5-year IVRFS, no variables remained as significant predictive factors over time after surgery. CONCLUSION: Our study provides valuable information for practical survival estimation and relevant prognostic factors for patients with UTUC after surgery.

PURPOSE: To evaluate the usefulness of transperineal sonography of the prostate in patients with previousabdominoperineal resection. MATERIALS AND METHODS: Transperineal prostatic sonograms were obtained from ninepatients with abdominoperineal resection. The shortest distance between the probe and the prostate gland, itsvolume, and its internal and external structures were evaluated for image quality, shape, border, and the degreeof distortion in internal echo. Because the number of patients was small, statistical analysis was not performed. RESULTS: Transperineal sonography of the prostate in eight patient was obtained at ease, except that one of ninepatients was not able to continue the procedure because of severe tenderness of the perineum and poor cooperation.Acceptable images of the prostate gland and their adjacent structures were obtained in one patient with less than1cm between the probe and prastate gland, three of four with between 1cm and 1.5cm, and one of three with morethan 1.5cm. CONCLUSION: In patients with previous abdominoperineal resection, transperineal sonography of theprostate may be a good imaging modality.

BACKGROUND/AIMS: Gabexate, a protease inhibitor, has been known to prevent pancreatic damage following ERCP. We conducted a prospective and randomized study to assess the preventive effect of gabexate. Methods: Of the 96 patients enrolled, 46 were treated with gabexate and 50 with placebo. The groups were similar with regard to sex, age, body-mass index, and the final diagnosis of ERCP. RESULTS: 24 patients (25.0%) had elevated pancreatic-enzyme levels; the frequency was similar in the two groups (P=0.48). Mean serum amylase value at 4 hours after ERCP was similar in patients with elevated basal level (220.5+/-43.2 U/L) and those with normal basal level (170.4+/-31.2 U/L). After the procedures, serum amylase values were lower in the gabexate group (137.1+/-19.8 U/L) than in the placebo group (212.0+/-50.4 U/L). The differences were not significant in the mean levels of amylase between the groups for any of imaging of the pancreatic ducts (pancreatic-duct imaging, 201.5+/-49.4 U/L, bile-duct imaging, 153.7+/-30.0 U/L). But in the patients with pancreatic duct imaging, serum amylase values were significantly higher in the placebo group (295.0+/-97.6 U/L) than in the gabexate group (112.0+/-10.6 U/L)(p<0.05). CONCLUSIONS: Prophylactic treatment with gabexate does not reduce pancreatic damage related to ERCP, but only in the patients with pancreatic duct imaging there were the significant differences between in the gabexate group and in the placebo group.

Occlusive disease of the iliac segment, proximal to the transplant artery (prox-TRAS), in kidney transplant recipients is a rare complication. Prox-TRAS, located in the common iliac artery, is extremely rare in these patients. Herein, we present an interesting case of a common iliac artery stenosis that manifested as decreased allograft function and uncontrolled blood pressure without other typical clinical symptoms. The patient was successfully treated with percutaneous luminal angioplasty and stent insertion.

The purpose of this study was to investigate the consumption and perception of high caloric-low nutrient dense foods in middle school students in the Daegu. Among 550 questionnaires distributed to students in Daegu, 528 (256 boys and 272 girls) were analyzed. A little higher than 80% of students ate snacks everyday, and 43.4%, 29.0%, and 8.1% ate snacks once, twice, and three times or more per day, respectively. Snacks and foods most frequently consumed were ice cream, fried noodles, drinks, cookies, and baked goods. Energy supply from snacks was 104.8~356.9 Kcal/intake while that from meal substitution foods was 520.7~980 Kcal/intake. Students' knowledge score of high caloric-low nutrient dense foods was 6.51+/-3.02 out of 10 points. Sixty percent of students did not read nutrition labels, but 67.9% of them thought that they need nutrition education by nutrition teachers. Students recognized the criteria of high caloric-low nutrient dense foods as well as proper food selection for essential educational items, It was concluded that effective education should be implemented in middle schools by nutrition teachers for students to develop good habits in selecting snacks and foods.

BACKGROUND/AIMS: Peritoneoscopy allows the clinician to assess the activity of the surface of the liver and helps him to make a prognosis in cases of liver disease by judging the structural changes of the surface. In chromoperitoneoscopy using an intravenous injection of indocyanine green (ICG), hepatic parenchyme is stained after intravenous injection of ICG while interstitial connective tissue, fatty deposition and hepatoma are not. So diagnostic accuracy is, therefore believed to be elevated in chromoperitoneoscopy than conventional peritoneoscopy or blind liver biopsy. This study was performed to assess the clinical usefulness of chromoperitoneoscopy in various chronic liver diseases. METHODS: Intravenous ICG was administered at 2 mg/Kg mixed with 20 cc of saline in 30 cases with several kinds of hepatic disorders during conventional peritoneoscopic examinatians. Liver surface was examined 5 minutes after ICG injection.

PURPOSE: This study aimed to identify the range of normal facial asymmetry using three-dimensional CT and to develop a simple method of diagnosis of facial asymmetry. MATERIALS AND METHODS: Twenty eight adults with normal occlusion (16 males and 12 females; mean age 24 years and 1 month) were selected, whose faces were assessed to be symmetric by an orthodontist. Three-dimensional reconstructions were obtained utilizing spiral CT scans and an oral and maxillofacial radiologist evaluated nineteen anatomic landmarks in three-dimensional coordinates. Facial asymmetry index of each landmark was caluculated. RESULTS: The range of normal facial asymmetry of each landmark was identified using mean and standard deviation of facial asymmetry index. CONCLUSION: The range of normal facial asymmetry identified in this study may be used as a diagnostic standard for facial asymmetry analysis.
