PURPOSE: To determine the preferred method of drinking water before spiral CT scanning of a gastric lesion. MATERIALS AND METHODS: Spiral CT scans of 92 patients with gastric lesion were obtained and evaluated. Patients drank tap water as oral contrast material and were scanned in the prone position; they were divided into two groups according to the method by which water was ingested. Group 1 patients drank 500ml 60 minutes before scanning; 500mL, 30 minutes before scanning; and 500mL just before scanning, while those in group 2 drank 800-1000mL just before scanning. In all cases, precontrast images were obtained, and an additional 300mL of water was given if the stomach was not adequately distended. Postcontrast images were obtained at 35 seconds, 80 seconds and 3 minutes after the start of infusion of contrast material. For 35- and 80-second scans, spiral CT was performed with 5-mm collimation, 7mm/sec table feed, and 5-mm reconstruction interval; for precontrast and 3-minute scans, 10-mm collimation, 10mm/sec table feed, and 10-mm reconstruction interval were used. There were 40 patients in group 1, and 52 in group 2. The images of the two groups were evaluated according to three criteria: gastric distension, mucosal enhancement, and tumor distinction. For each criterion, the images were evaluated by grading; an 'excellent' image scored 3, 'good' 2, 'ordinary' 1, and 'poor' 0. The differences in imaging quality between the two groups were statistically evaluated. Images obtained at 35 and 80 seconds, and at 3 minutes after the start of infusion of contrast material were compared, and the detectability of 18 confirmed cases of early gastric cancer was evaluated. RESULTS: For gastric distension, the mean score was 1.65 in group 1, and 1.81 in group 2 (P=0.33); the corresponding figures for mucosal enhancement were 1.45 and 1.65 (P=0.11), and for tumor distinction, 1.30 and 1.52 (P=0.09). Between the two groups, there was therefore no statistical difference in image quality. With regard to postcontrast images, those obtained after a delay of 35 seconds were best; those obtained at 80 seconds were better than those obtained at 3 minutes. Fifteen of 18 case of early gastric cancer were detected on spiral CT, and the detection rate was 83.8%. CONCLUSION: No statistically significant difference was seen between the two groups, and a single drink of water-just before scanning- is thus preferable to several drinks. Two scans, with images delayed for 35 and 80 seconds after contrast enhancement, are adequate. The use of these methods may improve the image quality of gastric lesions and the detection rate of early gastric cancer.

Although the ultlrasonography has been regarded as a main procedure in the diagnosis of bile duct andgallbladder diseases, a few reports concerning the ultrasonographic findings of biliary ascariasis appeared in theliterature. Seven cases of real-time ultrasonographic diagnosis of biliary ascariasis were made in our hospitalduring last 15 months. In six, the diagnosis was confirmed by surgery or radiographic examination. The resultswere as follows; 1. The characteristic long, thick, highly reflective echo without distal acoustic shadowing inthe extra and/or in tra-hepatic ducts were seen in all six proven cases. 2. The echogenic, nonshadowing images ofthe worms were seen as single stripe in five cases(containing a central longitudinal, anechoic tube, suggestingits digestive tract in three cases ) or multiple stripes in one case. But so-called coiled appearance or amorphousfragments were not seen in our cases. 3. Associated findings were as follows; mild to moderate dilatation of theextrahepatic duct in all six duct in 1 case, intrahepatic stone in 1 case, contracted gallbladder containingsingle stone in 1 case and evidence of cholecystitis in 4 cases. 4. One false positive diagnosis of ascariasis inthe gallbladder is considered due to reverberation artefact. No false negative was seen.

Although the ultrasonography has been regarded as a important procedure in the diagnosis of intraabdominalabscess, there were relatively few papers concerning the ultrasonographic findings of periappendiceal abscess.Nineteen cases of surgically proven periappendiceal abscess caused by perforated appendicitis were studied byultrasonography at the Kyung Hee University Hospital during last 34 months. The results were as follows; 1.Diagnostic accuracy of the real-time ultrasonography was 94.7%(18/19). There were only one false positive and onefalse negative. 2. The location of abscesses were ; periappendiceal 68.4%(13/19), pelvic 21.0%(4/19), subhepatic5.3%(1/19) and subphrenic 5.3%(1/19) in order of frequency. 3. Variable echo-patterns of abscesses wereencountered. But irregular, thick walled, posteriorly reinforcing, echo-free or mixed echo-patterns were mostcommon.

The pattern of thickening of the extrahepatic bile duct on computed tomography was analysed in 30 cases with recurrent pyogenic cholangitis diagnosed by surgery (n=19) or clinical basis (n=11). The mean wall thickness of the extrahepatic bile duct was 3.3mm (range, 1-6.3mm). Diffuse thickening of the extrahepatic bile ductal wall was demonstrated in 26 of 30 cases. Diffuse thickening of the extrahepatic bile duct in recurrent pyogenic cholangitis may be differentiated from focal thickening of duct in a common duct cancer or pancreatic cancer.

A 9-year-old Korean boy with lissencephaly was found dead at home. He had previously been diagnosed with lissencephaly that presented with infantile spasm on the basis of magnetic resonance imaging and electroencephalogram results. Antemortem chromosomal banding revealed a normal karyotype. A legal autopsy was requested to eliminate the possibility of neglect or abuse by his parents. The autopsy findings revealed type I lissencephaly with the associated microcephaly. No external wounds or decubitus ulcers were noted. Postmortem fluorescence in situ hybridization for the LIS1 locus and nucleotide sequence analysis of the whole coding regions of the LIS1 gene did not reveal any deletions. The antemortem and postmortem findings revealed that lissencephaly syndrome was associated with isolated lissencephaly sequence. External causes of death were excluded by the full autopsy and toxicology test results. Because patients with mental retardation are frequently victimized and suffer neglect or abuse, thorough external and internal examinations should be conducted at the time of autopsy.

Asymmetrical Septal Hypertrophy(ASH), Characterized by interventricular septal hypertrophy, is not an uncommon cardiac disease. Arrythmia occuring in ASH are supraventricular tachycardia, atrial premature beats, and ventricular premature beats. In about 10% of patients, there is a short P-R interval and a partial delta wave, suggestive of a variant of the Wolff-Parkinson-White syndrome. We reported here a case of ASH associated with W-P-W syndrome and paroxysmal atrial fibrillation with review of pertinent literatures.
