PURPOSE: To describe the MR findings of simple bone cyst. MATERIALS AND METHODS: We analyzed the signal intensity of the cystic contents, their margins, and internal septae, and the presence of bony fragment and pathologic fracture, and enhancement patterns in MRI of 10 pathologically confirmed simple bone cysts. RESULTS: On MR imaging, the cystic contents were of homogeneously low signal intensity on T1WI and high signal intensity on T2WI in nine cases and fluid-fluid level was seen in one case. The cystic margins were dark in all sequences. There were not any fragment in the cysts. Among the four cases with pathologic fracture, one case had fluid-fluid level and two had some areas of enhancement in the cyst or adjacent soft tissue. All nine cases with gadolinium enhancement showed thin rim enhancement along the inner margin of the cysts and internal septae. CONCLUSION: Homogeneous fluid-like signal intensity of cystic content and thin rim enhancement of margin and internal septae in MR imaging are believed to be helpful in the diagnosis of simple bone cyst.

Illuminating type poster looks very impressive and one may feel as if it were on the view box in his readingroom. Some difficulties and nuisances really exist in making them and a few of demerits can also be encounteredthat of contrast enhancement and of rough graininess. Contact print renders the best quality, though, KodakTechnical-Pan film with HC-110 (Dil. F) developer, llford xp 1–400 with Kodak C-41 color developer and KodakPlus-X with Microdol-X developer combinations also work in minimizing the deterioration of resolution and grainisswhich can almost always occur in enlargement prints.

OBJECTIVE: Uterine cervical cancer is the most common malignant tumor in Korean women. Human papillomaviruses are associated in 85-90% of the cases. However, other cofactors are considered to be important in carcinogenesis. There is an evidence that the uterine cervix is the site of shedding of the Epstein-Barr viruses(EBV). Furthermore the virus has been detected in cervical intraepithelial neoplasia and invasive carcinoma of the uterine cervix. We studied to evaluate the role of EBV in cervical carcinogenesis. METHODS: Non-neoplastic cervices(12), carcinoma in situ(32), microinvasive squamous cell carcinomas(9), invasive squamous cell carcinomas(37) and adenocarcinomas and adenosquamous carcinomas(14) were studied for EBV infection. PCR and in situ PCR for EBNA-1 were done and subtyping was done using PCR for EBNA 3C. RESULTS: In non-neoplastic cervix, EBV was detected in 16.7% by PCR and found in normal epithelial cells and lymphocytes in in situ PCR. By PCR technique, EBV was detected in 65.6% of CIS, 66.3% and 51.4% of microinvasive and invasive squamous cell carcinomas, 57.1% of adenocarcinomas and adenosquamous carcinomas. EBV subtyping was done in EBV positive cases by PCR and all showed type 1. CONCLUSION: EBV was detected in higher frequency in cervical cancer than in non-neoplastic cervix. However the frequency was not correlated to the invasion depth and histologic types of cervical carcinomas. EBV was detected in tumor cells as well as normal epithelial cells and lymphocytes also. It was suggested that EBV may play a role in cervical cancers but the mechanism in carcinogenesis remains to be solved.

To find any specific radiologic findings of skeletal metastases from hepatocellular carcinoma, we analyzed plain radiographs(n=25), CT(n=16) and MRI(n=5)of 25 patients with metastatic bony lesions from hepatocellular carcinoma. Vertebrae(17/25) and rids(16/25)were most frequently involved and 16 cases showed multiple metastases. The size of the lesions was larger than 5cm in 17 cases. Plain radiographs showed osteolytic destruction(2/25). CT(n=16) showed osteolytic destruction with an isodense expansile mass in all cases. Focal low attenuations suggesting necrosis were found in 2 cases. Calcification within the mass was not detected. MRI(n=5) showed a slight hyperintense area on T1WI and a defimte hyperintense mass on T2WI. After gadopentetate dimeglumine enhancement. The mass showed irregular enhancement. We concluded that skeletal metastatic lesions from hepatocellular carcinoma showed relatively large osteolytic destruction accompanying soft tissue mass and minimum central necrosis.

Pecutaneous transhepatic portogram with selective catheterizatio of the portal vein and its tributaries notonly provide information about the status of portal circulation and but can also be used in the treatment ofbleeding esophageal varices by selective embolization with various embolic materials. The authors describe easierand safer modified method of conventional percutaneous transhepatic portogram. We wish to describe our experiencewith the technical aspects and portosystemic collateral patterns in 26 patients with variceal bleeding, from July1985 to July 1986 at Kyungpook National University Hospital. 1. To overcome the difficulties of catheter passageand superselection of variceal supplying vein, we used 7F sheath directly introduced over the ,018″ guide wire.We used coaxial system using 25cm 18G needle within 7F vessel dilator to make the tip of dilator more rigid. 2.Variceal obliteration attempted in 23 patients who showed variceal supplying veins on the protogram, Successfulobilteration was obtained in 20 patients. We used absolute ethanol, stainless steel coil, and Gelfoam cubes withsclerosing and embolica agent of variceal vein. 3. Portosystemic collaterals of 24 patients; Coronary vein;21cases, Inferior mesenteric vein:9 cases, Short gastric vein:7 cases, Umbilical & paraumbilical vein; 6 cases,Gastrorenal: 3 cases, Splenorenal: 2 cases, Splenoretoperitoneal: 1 case. 4. The number of coronay vein were 18cases of single and 4 cases of two. The locations of coronary vein: Splenic vein: 13 cases, Main portal vein: 7cases, Junctional area: 6 cases. 5. Transhepatic obliteration of the gastroesophageal veins is a relatively simpleand usually successful form of palliative treatment for actively bleeding and stable gastroesophageal varices.

We experienced two cases of Gaucher's disease of adult type in brother aged four years and two years. The patients showed hepatosplenomegaly with anemia and thrombocytopenia. Typical Gaucher cells were found in bone marrow and biopsy specimens of liver and spleen through light and electron microscopic examination. Splenectomy was followed by improvement of anemia and thrombocytopenia. A brief review of literature was made.

BACKGROUND: Electroconvulsive therapy (ECT) that works by electrically inducing grand mal seizure is an effective therapy for patients with major psychosis and affective disorders. But ECT may produce intense stimulation of the central nervous system resulting in hypertension and tachycardia. Such an acute hyperdynamic state may be undesirable because of possible cardiovascular complications. We compared the ability of different bolus doses of esmolol to blunt the hemodynamic effects of ECT. METHODS: Twenty ASA physical status 1~2 patients were enrolled in a crossover design study to determine the effects of two standard esmolol bolus doses (0.5 mg/kg and 1.0 mg/kg) on the hemodynamic response and seizure duration during ECT. In each patients receiving esmolol or placebo, arterial pressure, heart rate, seizure duration and peripheral oxygen saturation (SpO2) were recorded. RESULTS: The seizure duration with placebo was 43 +/- 9 sec, esmolol 0.5 mg/kg bolus dose was 39 +/- 14 sec and esmolol 1.0 mg/kg bolus dose was 39 +/- 12 sec, but it was not significant. Compared with esmolol 0.5 mg/kg bolus dose, esmolol 1.0 mg/kg bolus dose decreased blood pressure and heart rate during ECT more effectively. CONCLUSIONS: Esmolol 1.0 mg/kg bolus dose was considered to be the better dose in blunting the hyperdynamic response during ECT without shortening of seizure duration.
