Nerve compression syndromes can be caused by compression of the peripheral nerve from interior or exterior of the nerve. In the upper extremities, brachial plexus, ulnar nerve and median nerve can be compressed in thoracic outlet syndrome, cubital tunnel syndrome and carpal tunnel syndrome respectively. Because these syndromes are caused by compression, decompressive management can be expected to be the principle of treatment. From Jan. 1980 to Dec. 1988, 94 patients were admitted and treated for nerve compression syndromes of the upper extremities in Seoul National University Hospital. Among these, 52 patients suffered from carpal tunnel syndrome and operation was performed to 86 hands. Twelve patients suffered from thoracic outlet syndrome and 25 from cubital tunnel syndrome. Ten patients were treated with conservative method and 84 with decompressive surgery. Satisfactory results were obtained in 92.3% of carpal tunnel syndrome and 84% of cubital tunnel syndrome. Of 4 operated cases of thoracic outlet syndrome, 3 cases were satisfactory.

Authors have reviewed a series of 41 cases of fibrous dysplasia which were treated surgically at the Department of Orthopedic Surgery, College of Medicine, Seoul National University. After mean follow-up of 25 months, we summarized the results as follows; 1. Among the 41 patients, 20 were male patients(M:F= 1:1.05). The average age was 20.2 years old. It was the most common in the 2nd decade(44%). The most common site was femur (53.6%) followed by tibia (28.6%) in monostotic type. Each polyototic patient had 3.8 locations in average. 2. The results were better in skeletally mature patients (86%) than in immature patients (42%). 3. Satisfactory results seemed to be expected in monostotic type (71%) than polyostotic type(33 %) 4. Satisfactory results seemed to be expected in sclerotic type(78%) than cystic type(50%) or ground glass appearance type (62%). 5. Autograft(71%) was superior to xenograft(40%) in our study. However, xenograft only or xenograft with autograft can be a recommendable method of treatment for a very large lesion or for a patient with insufficient graft donor site.

OBJECTIVE: To evaluate the usefulness of alendronate for prevention and treatment of postmenopausal osteoporosis this study was taken. METHODS: This prospective randomized clinical trial examined the effects of oral alendronate and HRT(conjugated estrogen plus medroxyprogesterone acetate), in combination and seperately, on BMD, biochemical markers of bone turnover in 79 women with low bone mass. Treatment included alendronate(10mg daily) plus HRT(group I, n=38), or HRT(group II, n=41) for 6 months. Bone density measurements were performed at months 0 and 6 at the lumbar spine. Biochemical markers of bone turnover were also measured every three months. RESULTS: Serum Osteocalcin decreased by 19.2% in group I and by 10.0% in group II at 3 months(p<0.05), and by 30.9% in group I and by 19.8% in group II at 6 months(p<0.05). Urinary deoxypyridinoline showed decrease of 19.75%(I) vs. 10.4%(II) at 3 months, 30.1%(I) vs. 20.7%(II) at 6 months, the difference was significant. Percent change of BMD measurements from baseline at 6 months in group I was 6.2% and in group II 0.6% on the lumbar spine(p<0.05). CONCLUSION: The treatment with alendronate is useful to postmenopausal women with osteoporosis by decreasing bone turnover markers, and by increasing the BMD.

PURPOSE: There has been much debate about the significance of the CA19-9 level for predicting the prognosis of colorectal cancer patients. This study aimed to evaluate the prognostic value of the preoperative serum CA19-9 level and the CA19-9 expression in the tumor tissues of colorectal cancer patients METHODS: One hundred patients with colorectal cancer and who had been treated by resection were studied. We assessed the correlations of the preoperative serum CA19-9 level and the status of the CA19-9 immunohistochemical staining with the clinicopathologic features, including the prognosis of the patients. RESULTS: The preoperative serum CA19-9 level had significant correlation with the status of CA19-9 immunohistochemical staining. The presence of distant metastasis was significantly correlated with an elevated level of serum CA19-9. The depth of tumor, the presence of lymph node metastasis, the TNM stage and tumor cell differentiation were significantly correlated with the status of the CA19-9 immunohistochemical staining. In addition, the gross morphology, depth of tumor, the presence of lymph node metastasis, the TNM stage, the status of the CA19-9 immunohistochemical staining and the serum CEA level were correlated with survival on univariate analysis. However, multivariate analysis did not validate the status of CA19-9 immunohistochemical staining as a significantly independent predictor of the prognosis. CONCLUSION: The CA19-9 expression was frequently observed in advanced stage tumor tissue, yet its expression in tumor tissue or the preoperative CA19-9 serum level did not show independent prognostic value for colorectal cancer patients.

Coronary magnetic resonance angiography (CMRA) allows a noninvasive assessment of the coronary anatomy without exposing the patients to radiation. It is also superior to coronary computed tomography angiography (CCTA) for the evaluation of luminal narrowing in heavily calcified coronary segments. We report a case with triple-vessel disease, but it could not be accurately assessed by CCTA because of calcification and lack of a significant perfusion defect or myocardial scarring on cardiac magnetic resonance imaging (MRI). However, whole-heart CMRA performed as part of the cardiac MRI protocol demonstrated significant triple-vessel disease with left main involvement, confirmed by subsequent invasive angiography with a fractional flow reserve measurement.

BACKGROUND/AIMS: Vascular endothelial growth factor (VEGF) is a potent angiogenic factor. Hepatocellular carcinoma (HCC) is a typical hypervascular tumor and VEGF may play a important role in its carcinogensis and progression. Transcatheter arterial chemoembolization (TACE) which is one of the therapeutic modalities of HCC induces hypoxia to the tumor. VEGF is known to be up-regulated by hypoxia. In this study, we examined the level of VEGF in the course of TACE. METHODS: Twenty-two HCC patients were enrolled in this study. Serum VEGF level was investigated before and 1, 5 and 10 days after TACE. The correlation of clinical factors of patients and the level of serum VEGF before TACE was evaluated. Platelet count was also measured with VEGF. RESULTS: Mean serum VEGF level increased significantly 1 and 5 days after TACE. Platelet count decreased significantly 1 day after TACE. Serum VEGF level was positively correlated with platelet count before and 1 day after TACE. CONCLUSION: TACE may increase the serum level of VEGF induced by hypoxia.

We cloned the full-length cDNA of O Manisa, the virus for vaccinating against foot-and-mouth disease. The antigenic properties of the virus recovered from the cDNA were similar to those of the parental virus. Pathogenesis did not appear in the pigs, dairy goats or suckling mice, but neutralizing antibodies were raised 5-6 days after the virus challenge. The utilization of O Manisa as a safe vaccine strain will increase if recombinant viruses can be manipulated by inserting or removing a marker gene for differential serology or replacing the protective gene from another serotype.

OBJECTIVE: Although cyclophosphamide (CYC) is effective for the treatment of diffuse proliferative lupus nephritis (DPLN) and severe membranous nephropathy (MN), it has serious adverse effects. Therefore, we evaluated our clinical observations with mycophenolate mofetil (MMF) for empirical treatment of DPLN and severe MN. METHODS: Seventeen patients with biopsy proven severe MN (n=8) and DPLN (n=9) received MMF for > or = 6 months as primary treatment (n=9) or subsequent maintenance therapy after CYC treatment (n=8). Treatment outcome was evaluated by random urine protein/creatinine ratio (UP/Cr) and serum creatinine (sCr) at the start and at 12 months and compared by the Wilcoxon signed-rank test. RESULTS: Overall, the mean (+/-SD) UP/Cr decreased in both MN (6.48+/-3.03 vs. 1.31+/-1.22, p= 0.016) and DPLN (3.77+/-2.34 Vs 0.83+/-0.53, p=0.043) patients. No significant change in serum Cr was detected in both MN and DPLN patients. Adverse events included nausea/abdominal discomfort (n=1) and menstrual irregularity (n=1). CONCLUSION: Short term empirical treatment with MMF in the majority of patients with severe MN and DPLN was well tolerated and effective in decrease of proteinuria and stabilization of renal function. Controlled clinical trials are necessary to define the role of MMF in the treatment of severe MN and DPLN.

BACKGROUND: Recombinant human erythropoietin (rHuEPO) is an established treatment for renal anemia. We aimed to determine that high dose subcutaneous epoetin alfa is as efficient and safe as usual dose for treating anemia in peritoneal dialysis patient. METHODS: Twenty four patients on CAPD were randomly assigned to either 10, 000 IU (high dose group, n=12) or 4, 000 IU (usual dose group, n=12) epoetin alfa regimen with variable interval for 24 weeks. If hematocrit was out of range (30-39%), the interval was changed within 50% of previous interval. RESULTS: Mean hemoglobin levels at randomization and after 12 weeks and 24 weeks were 11.4+/-1.3, 11.3+/-1.1, and 11.6+/-1.2 g/dL in high dose group compared with 10.8+/-0.8, 11.5+/-1.1, and 10.9+/-1.2 g/dL in usual dose group (p<0.05). The mean weekly epoetin alfa dosages at randomization and after 12 and 24 weeks were 93.2+/-45.3, 95.5+/-33.6, and 102.5+/-43.6 IU/kg in high dose group compared with 78.8+/-29.4, 75.9+/-20.6 and 75.5+/-39.7 IU/kg in usual dose group (p<0.05). But, interval in high dose group was two times as longer as usual dose group. Adverse events were generally mild and transient CONCLUSION: This study demonstrates that epoetin alfa 10, 000 IU is as efficient and safe as 4, 000 IU with similar weekly dose in CAPD patients. epoetin alfa 10, 000 IU administration reduces frequency of injections about one half.

Polyomavirus BK viral allograft nephritis is a great challenge in posttransplant management and graft survival because of difficulty in diagnosing and treatment. Initial treatment usually involves reducing immunosuppressive medications. However if concomitant acute rejection exist, it is more challenging in managing these patients, because acute rejection requires increase in immunosuppression. We present a case of a 35-year-old man who developed BK viral allograft nephritis and concomitant acute rejection 3 months after transplantation. BK viral allograft nephritis was missed in diagnosis and only pulse steroids for anti-rejection therapy was done. Initially, renal function was improved, but 4 months later, he presented with deterioration in renal function. Second renal biopsy showed BK allograft nephritis without rejection. BK viral DNA in plasma by PCR and urinary decoy cell were also positive. Reduction in immunosuppression by discontinuing mycophenolate mofetil stabilized the deterioration in renal function, however it failed to clear viremia.
