BACKGROUND: It has been well known that absolute and interpeak latencies of brainstem auditory evoked potentials (BAEP) are usually prolonged in diabetics. However, Its etiology is still controversial. We tried to identify whether the cause is structural or metabolic in origin by performing BAEP and brain MRI in the diabetic patients. METHODS: BAEP were performed in both the diabetic patients (DM) group (16 males and 15 females) and the normal control group (25 males and 33 female). A brain MRI was performed in the DM group on those who showed abnormal BAEP and com-pared the results of BAEP of the DM group with those of the control group. RESULTS: 7 patients (22.6%) showed abnor-mal BAEP (male; 6, female; 1, unilateral; 4, bilateral; 3) when abnormal BAEP was defined as being larger than two and a half standard deviations of the control group BAEP results. Two males of the DM group who showed abnormal structural lesions of the pons in their brain MRI were not included in the statistical analysis. The remaining 14 diabetic male patients (mean age: 58.7 +/-9.1 years, mean disease duration: 6.1 +/-4.7 years, mean hemoglobin (Hb) A1C: 7.7 +/- 2.0%) and 15 diabetic female patients (mean age: 60.6 +/-10.8 years, mean disease duration: 5.4 +/-5.1 years, mean HgA1C: 7.8 +/-2.1%) were stastistically analyzed. Interpeak latencies of I-III, III-V, and I-V were found to be signifi-cantly prolonged in the DM group. The prolongation of interpeak latencies of I-III and I-V were found to be signifi-cantly correlated with the disease duration only in the diabetic female patients, but not with age and HbA1c. CONCLUSIONS: These findings suggest that both metabolic derangement and structural lesion contribute to prolonging the central conduction time on BAEP pathway in diabetics.

Giant cell tumor is a relatively uncommon neoplasm with high rate of local recurrence following curettage and bone graft. The histologic grading was not proven useful in predictiog outcome. Histologically benign giant cell tumor may metastasize. We report a case of histologically benign giant cell tumor occurred at left distai femur with local recurrences and multiple pulmonary metastases which was proven by percutaneous needle aspiration lung biopsy. Recurred local lesion was treated by curettage and filling with methylmethacrylate and pulmonary metastases was treated with adriamycine and dacarbazine.

The authors have treated 30 cases of trochanteric fracture of the femur from June 1987, to July 1988 at Dong Suwon General Hospital. The 30 cases included, 8 Condylocephalic Kuentscher nailing, 9 Ender nailing, 7 Multiple pinning, 5 Antegrade Kuentscher nailing and 1 Row plating. 1. The shape of condylocephalic Kuentscher nail should be designed differently, contoured circular arc in anteroposterior and angled in lateral plane. In the anteroposterior plane : The length of the radius of the arc is measured by following way. 1) Design the shape of the nail on the X-ray film of the normal femur which was taken in full internal rotation of the leg. 2) Make three points in the femoral film. One is A, midcentral point of the femoral canal of the isthmus. Point B is center of upper lateral quadrant of the femoral head. Point C is apart from medial cortex 5-7mm at the level of entry portal of the nail. 3) Make point D: Draw the perpendicular lines from the right middle of the AB and AC. These lines meet at the point D. AD is radius of the arc of nail. Draw an arc measuring by the length of AD and mold the nail following the arc. In the lsteral plane ; The nail is bent into three or four segments and the length of the longest segment should not be exceeded the permissible length of straight nail, the latter is distance from entry portal of the nail to anterior cortex of the femur where the tip of the inserted nail is impinged, about 15cm. 2. Two different types of the Ender nailings are used depend on the type of the fracture. In intertrochanteric fracture, the trochanter is remained in the distal fragment and acts as the crane post to fix the proximal fragment(interfragmental compression screw fixation) by horizontal screw inserted through the lateral cortex of the distal fragment into medial cortex of the proximal fragment and fixed with another screw inserted into the distal fragment by tension band wiring. In transtrochanteric frscture, the proximal fragment is fixed by two different kinds of the nails, prior to the nailing medial displacement of the distal fragment is not reduced. The first nail is driven along the medial wall of the medullary canal of the distal fragment, the tip of the nail comes out of the fracture site and impinges to the inferomedeial aspect of the head along the out side of the neck. The nail is inserted into the head after correction of nail direction. The second and third nails are inserted through the medullary canal of the fragments. The proximal fragment is fixed between two nail groups. 3. Antegrade Kuentscher nailing is used for undisplaced trochanteric fracture with segmental fracture or comminuted, segmental subtrochanteric fracture. The open reduction and fixation is preferable in comminuted segmental subtrochanteric fracture for its accurate reduction. The authors msde additional several holes, transverse, sagittal (at the dorsum of the nail) oblique holes around the nail, so the interlocking screw can be easily inserted to the nail when the insertion of the screw through the transverse holes are difficult. 4. It's extremely important to study the fracture carefully when the surgeon plans to use the multiple pinning for trochanteric fracture. The fracture configuration has to be determined in regard to expect stability after local pinning especially in lateral plane. The fracture is fixed by horizontal pin, low angle pin, curved buttress pin(or screw) solidly, not parallel as in neck fracture. The curved buttress rush pin should be inserted as acting as the anteromedial or posteromedial buttress.

PURPOSE: The number of patients waiting for kidney transplantation is incessantly increasing, but the number of cadaveric kidney transplantations or ABO-compatible donors is so insufficient that ABO-incompatible kidney transplantation is being performed as an alternative. There are overseas studies and research showing that the 5-year survival rate and 5-year graft survival rate of ABO-incompatible kidney transplantation are not much different from those of ABO-compatible kidney transplantation. However, domestic research on the subject is rare. Therefore, we report the results of 22 ABO-incompatible kidney transplantation cases performed in our hospital. MATERIALS AND METHODS: This research was from 22 patients in our hospital who underwent ABO-incompatible kidney transplantation from 15 February 2007 to 20 May 2010. RESULTS: As yet, there have been no donor graft losses and no deaths after transplantation. The results of the two groups were analyzed by analysis of covariance of the creatinine value of the recipients at 6 months after the operation, corrected for the preoperative value in order to statistically identify whether there were differences in renal function after the operation between ABO-compatible and ABO-incompatible kidney transplantation. The results of the analysis of covariance showed no statistical difference in renal function after the operation between the two groups. CONCLUSIONS: Even though there were not many cases, our initial results for ABO-incompatible kidney transplantation were positive. Considering the increasing number of patients waiting for kidney transplantation, longer-term domestic research studies of ABO-incompatible kidney transplantation are necessary.

In Korean, there has been an increasing concern on rickettsiosis as a possile common cause of unknown febrile illness since Tsutsugamushi fever among koreans was reported first in 1986. We experienced 10 cases of Tsutsugamushi fever ocurring in the Mokpo area during the period of 3 months (Oct, to Dcc.) in 1990, which were diagnosed clinically and serologically by indirect immunofluorescent antibody test. The following results were obtained. The most frequent symptoms were fever (100%), headache (90%), chill (60%), conjunctival injection, and lymphadenopathy. Common laboratory findings were leukopenia (WBC<5000/mm3 30%), elevated ESR (>20mm/hr, 30%), positive CRP (60%), and elevated Alt/AST. Antibody titers against R. tsutsugamushi ranged from 1:80 to 1:1,280, but they showed no antibody reaction to Hantaan virus and leptospira. All patients showed good response to antibiotic therapy with chloramphenicol.

Streptococcus pneumoniae is the most common pathogen of bacterial meningitis in childhood. It causes such intracranial complications as hydrocephalus, cerebral edema, inappropriate secretion of antidiuretic hormone(SIADH), and convulsion, and also such cerebral vascular complications as vasculitis, thrombosis, aneurysm, infarction, and subarachnoid hemorrhage. We report a male of 4 months old who had intracerebral cortical hemorrhage and sinovenous thrombosis complicated by streptococcus pneumoniae meningitis. Also, we reviewed the literature on intracerebral vascular complications related to bacterial meningitis.

BACKGROUND/AIMS: The most effective method of improving survival in patients with HCC is early diagnosis and curative hepatic resection. However, longterm survival after curative resection remains low because of high recurrence rate after resection. The purpose of the study is to assess the prognosis and the efficacy of the various treatment modalities on recurrent HCC after curative resection. METHODS: The clinical records of 50 patients with recurrent HCC were reviewed retrospectively who underwent curative surgery in Yonsei University, Severance Hospital from Jan. 1987 through Oct. 1994. The cummulative recurrent rate after resection, the response rate of treatment after resection, the median progression free survival and the survival after recurrence according to the treatment modalities were evaluated. RESULTS: The cummulative recurrent rate after resection was 3.9% at 3 month, 8.3% at 6 month, 14.1% at 12 month, 21.5% at 24 month, 23.4% at 36 month and 24.4% at 60 month. The response rate of treatment after recurrence was 23.7% (9 patients). The median progression free survival of the patient with reoperation and hepatic embolization was 13.9 months, that of conservative treatment group was 6.8 months and that of no treatment group was 4 months(p = 0.004). The survival after recurrence of HCC was 19.7 months in reoperation and hepatic embolization group, 11.4 months in multimodality group, 16.9 months in conservative treatment group and 8.4 months in no treatment group(p=0.0998). CONCLUSION: Reoperation and hepatic embolization for HCC after curative resection was effective in improving progression free survival, but overall survival were not significantly different according to the treatment modalities. This results proposed that reoperation and hepatic embolization for recurrent HCC after curative resection improve progression free survival.
