PURPOSE: To compare the efficacy and safety of ultrasound guided automated gun biopsy with fine needle aspiration biopsy of focal liver lesions. MATERIALS AND METHODS: We performed 32 automated gun(19.5G Autovac Biopsy Needle) biopsies and 27 fine needle aspiration(22G Westcott Style Biopsy Needle) biopsies in 48 patients with malignant focal liver lesion under the guidance of ultrasound. We compared the "positive for malignancy rate" and "pathologic diagnosis rate" of both methods with final diagnosis, and the rate of complications. RESULTS: The "positive for maiignancy rate" of automated gun biopsy and needle aspiration are 84.4%(27/32) and 66.7%(18/27) respectively(p=0.11). The "pathologic diagnosis rate" are 84.4%(27/32) and 55.6%(15/27) with significant statistical difference(p<0.05). And there is no difference of the rates of significant complications. CONCLUSION: When compared with the fine needle aspiration biopsy, ultrasound-guided automated gun biopsy is safe and more effective method for malignant focal liver lesion.

To build and to manipulate clinical data in one of the important works in the hospital. In order to accurately append the data and to quickly find and display the informations as the user need, we developed a software program running on the personal computer. Our system largely consists of four parts; registration of the clinical and departmental data, retrieving tool of articles in the medical journal, collection of special data for clinical survey and display system of the various reports. In our experiences, we consider the key factors for systemic management of clinical rearch data base as the follows; work analysis for data processing, design of data base, coding and classification of basic data and technique of registeration. Of these standarized coding system of the orthopedic diseases appeare to be of it most importance.

Agressive osteoblastoma is a very rare primary bone tumor having locally aggressive and destructive natures.But distant metastasis is not well occurred. Aggressive osteoblastoma may be similar to osteoblastomaradiologically, but has different pathological featurs. We experienced one case of aggressive osteoblastomaarising from left ilium and report this case with review of the literatures.

BACKGROUND: Previous studies indicated that there was important correlation between early patency of infarct-related artery, preservation of ventricular function, and improved survival after thrombolytic therapy for acute myocardial infarction. An increased infusion rate of rt-PA has been shown to result in faster thrombolysis and a high patency rate of occluded vessel in myocardial infarction. Therefore, we evaluated the effect of simplified triple bolus injection of rt-PA on early patency of infarct-related artery and evaluated safety and efficacy of triple bolus injection. METHOD: Patients with acute myocardial infarction presenting up to 6 hour from the onset of chest pain were recruited for the study. Aspring(100-200mg) was given immediately. Total dose for 1.5mg/kg of rt-PA(minimum 75mg, maximum 100mg) was administered as triple bolus intravenous injections. The half of total dose was injected initially, the quarter of total dose was injected at 10 minutes after 1st injection and the remainder was injected at 40 minutes after 1st injection. Five thousand units of heparin was given and 1,000-1,500unit/hr was given continuously. Coronary angiogram was performed at 60 minutes and 7-10 days after the first bolus injection. RESULTS: At 60 minutes, eleven of fourteen patients (78.6%) showed TMI grade-3 of patency in infarct-related coronary artery. There were two patients of hemorrhagic complications. One patient developed cerebellar hemorrhage at third day after rt-PA injection, and the other developed bleeding at femoral sheath site. There was no in-hospital mortality and reinfarction. CONCLUSION: In patients with acute myocardial infarction, the simplified triple bolus injection of rt-PA is associated with high early patency(TMI grade-3) in infarct-related coronary artery, with low risk of major bleeding comlications comparable to other studies.

Profound reduction of anterograde coronary flow with concomitant ischemia is seen occasionally during percutaneous coronary intervention despite technically successful procedure. We found interesting coronary flow pattern in a patient with acute myocardial infarction, showing angiographic no reflow phenomenon after direct PTCA. The coronary blood flow pattern of the angiographic no-reflow phenomenon in this case was characterized by minimal systolic flow and sharp deceleration of diastolic flow. Coronary flow reserve calculated by the ratio of adenosine induced maximal hyperemic velocity and basal velocity was reduced. The Dopplertipped guide wire was useful for observation of phasic coronary flow pattern of angiographic no-reflow phenomenon.

To differentiate amebic and pyogenic liver abscesses, sonography(US) and CT findings of 21 amebic and 22 pyogenic liver abscesses were reviewed retrospectively. US was performed in all cases and CT in 15 cases of each group. Eleven cases of amebic abscesses had well defined margin which was observed in 10 cases of pyogenic abscessed. Amebic abscesses showed hyperechoic wall in 7 cases and calcification in 4 cases. Ten cases of pyogenic abscesses had mearby intrahepatic duct dilatation which was observed in 2 cases of amebic abscesses. Pneumobilia was seen in 6 cases of pyogenic abscesses. US findings of clear margin and hyperechoic wall, and CT findings of intrahepatic duct dilatation, pneumobilia, and calcification were helpful in differentation of amebic pyogenic liver abscesses.
