Focal nodular hyperplasia is a benign hepatic tumor mainly composed of nodules of hepatocytes and Kupffer cells separated by fibrous septa. In general, it is difficult to differentiate focal nodular hyperplasia and hepatocellular carcinoma on ultrasonography, conventional CT(computerized tomography), and angiography. But IV bolus CT is of particular value in the diagnosis of focal nodular hyperplasia because it can divide enhanced CT into early and late phase and can characterize tumor vascularity and analyze any intratumoral elements. In our case, it was seen as a hypoechoic mass lesion on ultrasonograpl'hy and hyperdense mass lesion on early-phase IV bolus CF and isodense mass, lesion on late-phase IV bolus CT. On angiography, hypertrophy of the feeding artery and tumor staining were well visualized. The patient underwent operation and the mass was pathologically confirmed to a focal nodular hyperplasia. We report the first case of focal nodular hyperplasia on IV bolus CT in Korea.

Henoch-Schonlein purpura is a common pediatric disease presenting most frequently with skin, gastrointestinal, joint and renal manifestations. But in cases are infrequently only severe gastrointestinal manifestations. It is hard to diagnose promptly and exactly. Clinical manifestations and laboratory findings were observed and analyzed in 20 cases with Henoch-Schonlein purpura which were considered as acute abdomen, hospitalized at Kyung Hee university Hospital during the period from December, 1982 to September, 1992. The following results were obtained; 1) The age distribution of Henoch-Schonlein purpura had a peak incidence between 7 to 9 year old. And male preponderance was observed with male to female ratio of 2.33 to 1. 2) The most prevalent season for the initial presentation of Henoch-Schonlein purpura was in fall: in 10 cases (50%). 3) The frequency of each type of clinical manifestations showed 20 (100%), 20 (100%), 18 (90%), 8(40%) cases for skin, gastrointestinal, joint and renal manifestation respectively in order of frequency. 4) The common previous illness were URI, 40 cases (50%) and allergy, 2 cases (10%). 5) The onset time of skin manifestation from admission were 1 to 4 days (75%0, 5 to 8 days (15%), 9 to 12 days (10%) explolaparotomies were done the last 2 cases. 6) In all cases, X-ray study (100%), abdominal sono (50%), Meckels scan and colon study (5%) respectively were done. 7) Hematologically leukocytosis over 10,000/mm3 was observed in 80% of cases and increase in ESR over 20 mm/hr in 65% of cases. Coagulation studies, immunologic and complement level revealed the result within normal range in most of the cases. 8) Among 8 cases with renal involvement, all cases had both hematuria and proteinuria. 9) Most cases were recovered within 4 weeks but in 4 cases, renal biopsies were done because of relapse. The results were Meadow classification grade I (1 case), II (1 case), IVa (2 cases). After renal biopsy, steroid pulse therapy was started.

The Korean Society of Anesthesiologists began to take in training examination(Self Assessment) for the residents in April 1989. Two hundreds thirty four participants took the first examination and after that 343 in 1990, 399 in 1991, 455 in 1992 took the examination obviously the actual number is increasing each year. This study was done to see if there is any correlationship between the results of self assessment and board examination in the same population group. Ninety two persons who took self assessment in April 1990 and board examination in Jan 1991 and 108 persons who took self assessment in Sept. 1991 and board examination in Jan 1992 were investigated. In both groups we can see the close positive correlationships between the results of self assessment and written board examination.

BACKGROUND: Thoracic epidural anesthesia(TEA) is not commonly used for the purpose of pure regional anesthesia. To investigate the usefulness of TEA as a method of regional anesthesia, we performed TEA in patients(n=20) with breast mass. METHODS: After placement of thoracic epidural catheter at one of the 3rd, 4th, 5th or 6th thoracic intervertebral space according to the position of the mass, we injected 8ml of 2% plain lidocaine solution as initial dosage and 2~4 ml as additional dosage if necessary. Blood pressure and heart rate were measured before and at 5, 10, 15, 20, 25, 30, 60 and 90 minutes after epidural injection. Fifteen minutes after epidural injection, the extent of sensory block was measured at cephalad and caudad directions. Two-dermatome regression time was recorded postoperatively. We also investigated whether surgeon used lidocaine locally and anesthetist used intravenous analgesics or sedatives. And we observed the occurrence of complications associated with TEA. RESULTS: The induction dose of 2% lidocaine was 10.1+/-2.1 ml and total dose used was 11.4+/-2.1 ml. The extent of sensory block was T1.1+/-1.1 to T9.1+/-2.3 and two-dermatome regression time was 73+/-24 minutes. Blood pressure and heart rate showed stable pattern of change perioperatively. In two of the subjects, the surgeon used 4 ml of 1% lidocaine locally and in one of the subjects, 50 microgram of fentanyl was used intravenously. Another one of the subjects developed Horner's syndrome postoperatively, which soon disappeared without specific treatment. CONCLUSIONS: Above results suggest that TEA is suitable for breast mass excision as a method of regional anesthesia.

BACKGROUND: Headache is a common complaint in patients presenting to the emergency department(ED). Many patients suffered sustained headache even after presenting to the ED. This study investigate whether the patients were received analgesics and timely adequate. METHOD: We analyzed 131 adolescent and adult patients with non-traumatic headache without any neurologic deficit in two emergency department during 6 months period retrospectively. RESULTS: The positive and negative predictive value according to primary impression were 47% and 74% respectively. The mean time to take brain computed tomography(CT) after ED presentation was 120 minutes. The patients with primary impression of intracranial hemorrhage(mainly SAH) were the most fast(mean time 88+/- 70 minutes). 28(21%) patients were received analgesics before taking brain CT(after ED presentation), and 70(53%) patients after CT, 27(54%) patients after cerebrospinal fluid examination. The mean time interval were 43, 126 and 149 minutes on each group being received the analgesics. CONCLUSION: According to this study many patients suffered sustained headache before being classified to certain type of disorder. It may due to the reasons that there were no definite guidelines treating headache, the pain itself, or the physician treats patients as physician's way.

In a series of 20 young rats, three cortical lesions were made in each hemisphere. Two of these lesions were filled with avitene and gelfoam, while the third was left empty as a control. The animals were killed successively on weeks 1, 2, 4 and 8 after the operation. The results were as follows : 1) Although there was no difference in the type of tissue reactions, avitene was more rapid and profound than gelfoam in the process and degree of inflammatory reaction at the same periods. 2) Avitene biodegradaded more rapidly than gelfoam. 3) The extent of fibrosis and adhesion to the surrounding brain tissues were not grossly different between these two agents but more profound histopathologically in avitene at the same periods. With these results, we could conclude that the avitene was superior to the gelfoam as the hemostatic agent in neurosurgical area.
