PURPOSE: This study was attempted to investigate the prevalence of the expression of c-fos protein, TGF-alpha and -beta, PCNA , DNA ploidy pattern and histopathological parameters of giant cell tumor (GCT) of bone and to correlate with prognosis and to extend our understanding on tumorigenesis of GCT. MATERIALS AND METHODS: Twenty eight cases of paraffin-embedded tissue were studied, classified as recurrent (5 cases) and non-recurrent group (12cases) within the limits of the cases which afforded surgical material on first operation. RESULTS: No significant difference was observed in cellularity of stromal cells, atypia of stromal and giant cells, presence of hemorrhage and necrosis between recurrent and non-recurrent group. However, presence of more than 10 mitotic figures in 10 high power fields in recurrent group was significantly higher than non-recurrent group (p<0.05). The immunoreactivity for PCNA was seen only in nuclei of stromal cells, whereas nuclei of giant cells showed negative staining. The positivity of PCNA revealed no significant difference between non-recurrent (mean; 40.9%) and recurrent group (34.4%). The expression of c-fos oncogene was seen in 5 cases (100%) in recurrent group, and 8 cases (66.7%) in non-recurrent group, and no significant difference was seen. No significant difference of expression of TGF-alpha was seen in 5 cases (100%) in recurrent group and in 11 cases (91.7%) in non-recurrent group. The expression of TGF-beta in stromal cells was significantly higher in non-recurrent group (80%) compared to recurrent group (100%) (p<0.05). In DNA analysis out of 18 cases, 4 cases (22.2%) were aneuploidy and 14 cases (77.8%) were diploidy. Among 4 aneuploidy cases, 3 cases (75%) had no recurrence, and 1 case (25%) had metastasis to lung and expired. No significant difference of DNA ploidy pattern was seen between the recurrent and non-recurrent group. CONCLUSION: Presence of more than 10 mitotic figures in 10 high power fields and less expression of TGF-beta are related to higher possibility of recurrence and it is suggested that the number of mitotic figure (more than 10/10HPF) and expression of TGF-beta could be helpful parameters in predicting recurrence of GCT.

Neonatal lupus erythematous is a rare syndrome, which is characterized by a transient lupus dermatitis, hematologic abnormalities and isolated congenital heart block. We detected the atrioventricular dissociation, bradycardia and pericardial effusion by fetal echocardiography in a female fetus at 25th weeks of gestational age. The baby was born in the 38th week of pregnancy by Cesarean section with 1790 gram of body weight. In spite of atrioventricular dissociation with bradycardia and pericardial effusion, cardiac pacemaker was not needed during neonatal period because she was doing well, no evidence of congestive heart failure and around 80 beat per minute of heart rate. The serologic markers for diagnosis of neonatal lupus are the autoantibodies specific to SS-A/Ro and/or SS-B/La. These antibodies are produced by the mother and passed to the fetus through the placenta. Autoantibodies of cytoplasmic SS-A antigens or SS-B antigen were found in the blood of this patient and her mother. We report a case of neonatal lupus syndrome with congenital atrioventricular dissociation with Rt. Bundle branch block and hematologic abnormality.

PURPOSE: Surface finishing of a cemented femoral stem is a subject of controversy even though the contemporary cementing techniques have improved results. Using the Versys Heritage femoral stem, we evaluated the outcome of using a polished surface. MATERIALS AND METHODS: The subjects of this study were 95 hip arthroplasties in 82 patients and we used a cemented polished femoral stem with the 3rd generation cement technique and all the surgeries were done between October 2000 and August 2003. There were 58 male patients (64 hips) and 24 female patients (31 hips). The mean age at the time of the index arthroplasty was 52.3 years (26~74 years), and the average body mass index was 24.2+/-2.75 (19.1~29.8). The average follow up period was 80.7 months (64~109 months). All the hips were evaluated clinically by the Harris hip score and the thigh pain, and they were radiologically assessed by the cement grade and the presence of osteolysis around the femoral stem, as well as the presence of stress shielding of the proximal femur. RESULTS: At the final follow up, the Harris hip score for all the patients had improved from preoperative 58.9 (17-83) to post operative 91.7 (72~100). The cement grade was measured using Barrack's method. Of the 95 hips, 45 (47.3%) cases were grade A, 48 (50.5%) cases were grade B and 2 (2.1%) cases were grade C1 at the final follow up. There was 1 case of definite loosening. Stress shielding was noted in 65 (68.4%) cases of the zero grade and 19 (20.0%) cases of the 1st grade. CONCLUSION: In this study, the cemented polished femoral stem showed excellent results at the mid term with a minimum follow up of 5 years. But a longer-term follow-up study will be needed for further understanding the implications of cemented polished femoral stem.

OBJECTIVE: The purpose of this study was to provide management strategy and to improve management outcome of patients with unruptured intracranial aneurysms (UIA). PATIENTS AND METHODS: The authors reviewed the database as sources for identifying and analyzing patients, and analyzed the management outcome of patients with UIA. From June 1979 to June 1999, among total of 1,801 patients treated for intracranial aneurysms, 372 patients with 437 unruptured aneurysms were treated by surgery (335 patients) or neurointervention (37 patients). One hundred and forty - three patients with 158 UIA had no history of SAH from a different aneurysm (group 1), and 229 patients with 279 UIA had a ruptured aneurysm that have been repaired simultaneously or before treatment of UIA (group 2). We reviewed the rate of favorable (good, fair) and unfavorable (poor or dead) outcome one year after the treatment. RESULTS: The rate of favorable and unfavorable outcome in group 1 was 96.5% and 3.5% respectively. In Group 2, the rate was 93.5% and 6.5%. However, the most of the unfavorable outcome in group 2 came from treatment of the ruptured aneurysm, or SAH. The only significant factor contributed to unfavorable outcome in group 1 was size of UIA. Those of group 2 were age, Fisher grade, Hunt - Hess grade, and aneurysm number. Complications attributable to surgical or endovascular treatment of UIA that occurred in 38 of 372 patients (10.2%) were cerebral infarction (17), intracerebral hemorrhage (10), epidural hematoma (4), cranial nerve injury (3), infection (2), venous infarction (1), and subarachnoid hemorrhage (1). CONCLUSION: Rupture of an intracranial aneurysm is a devastating event. The safe size below which rupture is unlikely is unclear. There appears to be increased risk from unruptured aneurysms discovered in SAH patients. All unruptured aneurysms in healthy patients as well as in patients with history of SAH should be repaired.

OBJECTIVE: We report the correlation between known risk factors for cerebrovascular disease and formation of multiple intracranial aneurysms. METHODS: We reviewed the medical records and outcomes of 524 patients who had undergone aneurysmal operation at our hospital between January 1996 and May 2001. Of 524 patients who had undergone operations with intracranial aneurysm, 130 patients had multiple intracranial aneurysms. The authors examined the correlations between the risk factors(patient age, sex, menopausal state of female patients, hypertension, cigarette smoking) and the presence of multiple intracranial aneurysms by using chi-square test retrospectively. RESULTS: The male to female ratio was about 1 : 2.05(male : female=129 : 265) for patients with single intracranial aneurysm, and male to female was about 1 : 3.06(male : female=32 : 98) for patients with multiple intracranial aneurysms. Among 256 female patients with single intracranial aneurysm, 182 patients(68.9%) were postmenopausal, and, among 98 female patients with multiple intracranial aneurysms, 81 patients(82.6%) were postmenopausal. The mean age of the patients with single intracranial aneurysm was 54 years, and, with multiple intracranial aneurysms, the mean age was 57.8 years. The presence of hypertension was found in 149 patients(37.8%) with single intracranial aneurysm, and, in 55 patinets (42.3%) with multiple intracranial aneurysms. Cigarette smoking was found in 116 patients(29.4%) with single intracranial aneurysm and 47 patients(36.1%) with multiple intracranial aneurysms. CONCLUSION: There is a significant correlation between menopausal state of female patients and presence of multiple intracranial aneurysms. However, gender, hypertension and smoking are not related to multiple intracranial aneurysms.
