PURPOSE: We studied to evaluate the effect of percutaneous catheter drainage (PCD) in liver abscess. MATERIALS AND METHODS: We retrospectively analyzed clinical data (presence of fever, WBC count), radiological findings (computed tomography, ultrasonography and abscessogram) and correlated them with treatment period. Percutaneous drainage of liver abscess were performed in 19 patients under fluoroscopy guide during recent three years. RESULTS: Eighteen patients (95%) were cured, and one patient underwent surgery because of peritonitis caused by PCD procedure. Average treatment period was 17 days. CONCLUSION: In the treatment of liver abscess, PCD is thought to be safe and effective.

OBJECTIVES: A different sequence change, in the mitochondrial tRNA gene, has been proposed as a candidate mutation in the sensorineurnal hearing loss. The purpose of current study is to identify the association between the noise-induced sensorineurnal hearing loss and the A to G mutation at nucleotide 3243 of mitochondrial DNA. METHODS: Subjects were established by history and chart review, and audiological and clinical data were obtained. Blood was sampled from 101 controls, 50 noise-induced hearing loss, and 12 sensorineural deafness. The DNA of these individuals was extracted, and mitochondrial genome was analyzed by polymerase chain reaction. Subsequently, the coding sequence of mitochondrial genome was sequenced, and compared to the normal sequence, and all sequence variations were analyzed by restriction endonuclease ApaI. RESULTS: Mitochondrial DNA mutation (3243A->G) was not detected by polymerase chain reaction (PCR) in any patients with noise-induced hearing loss, sensorineural hearing loss, and normal control without hearing loss in Koreans. The DNA sequencing of PCR products did not revealed an A to G substitution at nucleotide 3243 of mitochondrial DNA. CONCLUSIONS: The noise-induced sensorineural hearing loss was not associated with mitochondrial DNA mutation (3243A->G)

PURPOSE: To assess the effects and complications of balloon dilatation in the treatment of postoperative stricture at the gastrointestinal tract. MATERIALS AND METHODS: From February 1991 to July 1993, balloon dilatation was performed under fluoroscopic guidance on 5 patients (age:l month to 64 yrs, male:female=2:3) who previously had undergone abdominal surgery because of stomach cancer (n=2), congenital tracheoesophageal fistula (n=l), lye stricture (n=l), and colon cancer (n=l). Causes of the stricture were all benign (n=4) except for one (recurrence of malignant tumor). We dilatated the stricture site with balloon catheter (8--25 mm in diameter) 3 to 4 times per session which was repeated 1 to 5 times in each patient. Follow-up periods ranged 8 to 15 months after the treatment. RESULTS: Two out of four benign strictures were relieved at one session, and the remaining two needed repeated sessions of balloon dilatation. Symptoms did not improve in the patient with malignant stricture in~pite of balloon dilatation, and feeding jejunostomy was reginred. Partial tear of anastomosis site occurred in one patient, however, it did not require any treatment. CONCLUSION: Balloon dilatation is relatively safe and effective in the treatment of postoperative stricture at the gastrointestinal tract.

Functional magnetic resonance imaging is a promising imaging technique developed recently to obtain functional maps of the brain, and can be successfully performed on widely available diagnostic MR imaging systems. Thus, the technical principle and application of this new imaging are no more minor part of knowledge in radiology. We describe herein the overview of functional magnetic resonance imaging about the physiologic mechanism, imaging technique, image-processing method and practical application.

Fat containing masses, except mediastinal lipomatosis, of the thorax are uncommon. In spite of uncommonoccurences, as CT can detect not only the fat content but also the presence and character of the non-fattycomponent of the mass, accurate preoperative diagnosis can usually be made in most cases of fat containingmediastinal masses. Authors report 6 cases of fat containing mediastinal masses, that were diagnosedpreoperatively by CT scan, comprising 2 cases of limpoma(combined with plexiform neurofibroma in a case), 1liposarcoma, 1 thymolipoma, and 2 cases of omental hernia through Morgagni foramen.
