The firat caae of hemangioma originating in the skeletal muscle was reported by Linton in 1843. Hemangiama involving the skeletal muscle ia less common and the correct preoperative diagnosis is often not made even tbough they attain considerable size. These tumors have remained asymptamatic and undetected by their hosta. We experienced 5 cases of hemangiama in the skeletal muscle for 2 years since 1979 and the diagnosis were confirmed clinicopathologically.

PURPOSE: Experimental studies have suggested that the stromal-derived factor-1 (SDF-1)/CXCR4 axis is associated with tumor aggressiveness and metastasis in several malignancies. We performed a meta-analysis to elucidate the relationship between CXCR4 expression and the clinicopathological features of prostate cancer. MATERIALS AND METHODS: Data were collected from studies comparing Gleason score, T stage, and the presence of metastasis with CXCR4 levels in human prostate cancer samples. The studies were pooled, and the odds ratio (OR) of CXCR4 expression for clinical and pathological variables was calculated. RESULTS: Five articles were eligible for the current meta-analysis. We found no relationship between CXCR4 expression and Gleason score (<7 vs. > or =7). The forest plot using the fixed-effects model indicated an OR of 1.585 (95% confidence interval [CI]: 0.793~3.171; p=0.193). Further, CXCR4 expression was not associated with the T stage ( or =T3), and the relevant meta-analysis showed OR=1.803 (95% CI: 0.756~4.297, p=0.183). However, increased CXCR4 expression was strongly associated with metastatic disease with a fixed-effects pooled OR of 7.459 (95% CI: 2.665~20.878, p<0.001). CONCLUSIONS: Our meta-analysis showed that the higher CXCR4 protein expression in prostate cancer specimens is significantly associated with the presence of metastatic disease. This supports previous experimental data supporting the role played by the SDF-1/CXCR4 axis in metastasis.

PURPOSE: To compare the effectiveness between minimally invasive plate osteosynthesis (MIPO) and interlocking IM nailing in the treatment of distal tibia fracture without involvement of ankle joint retrospectively. MATERIALS AND METHODS: 38 patients with distal tibia fracture from Jan. 2004 to Oct. 2005 were divided into two groups. Minimum follow-up was for 12 months. Group MIPO consisted of 18 patients were treated with MIPO and group Nail consisted of 20 patients were treated with interlocking intramedullary nail. The results were compared between two groups by assessing bony union time and operation time. Clinical evaluation was evaluated by Olerud score. RESULTS: The mean bony union time was 14.4 weeks (12~17 weeks) in group MIPO and 16.7 weeks (13~19 weeks) in group Nail (p=0.011). The mean operation time was 1.05 hours (0.6~1.6 hours) in group MIPO and 0.74 hours (0.4~1.1 hours) in group Nail (p=0.044). The Olerud score was 83.8 (75~100) in group MIPO and was 89.6 (70~100) in group Nail (p=0.075). In Complication, group MIPO showed one metal failure and two skin irritations, group Nail showed three superficial wound infections. CONCLUSION: MIPO was the shorter bony union time and the longer operation time than the interlocking intramedullary nailing. There were no significant differences between the two groups in clinical results.

Pulmonary hemorrhage is a rare but possibly fatal complication of systemic lupus erythematosus (SLE). We report a case of massive pulmonary hemorrhage in a 14-year-old boy recently diagnosed as SLE. He developed massive pulmonary hemorrhage during the courses of i.v. methylprednisolone pulse therapy, and did not respond to i.v. cyclophosphamide. However, he rapidly improved through the use of plasmapheresis. Although various factors can precipitate pulmonary hemorrhage in SLE, our case was probably caused by an immune mediated mechanism since the hemorrhage responded promptly to plasmapheresis. This case illustrates the importance of plasmapheresis in the treatment of pulmonary hemorrhage which is not improved by methylprednisolone and cyclophosphamide. We report this case with a brief review of the related literatures.

A 61-year-old man presented with a right renal mass with a vena caval thrombus on computed tomography that was consistent with renal cell carcinoma. The results of routine laboratory examinations and urinalysis were within normal limits. Preoperative planning was critical owing to the presence of the vena caval thrombus. A radical nephrectomy, vena caval thrombectomy, and regional lymphadenectomy were done. The pathologic report was consistent with a high-grade, invasive urothelial carcinoma, with sarcomatoid differentiation involving the renal vein and inferior vena cava (Stage IV, T4N0M0). Thus, this was a rare case of upper tract urothelial carcinoma. Adjuvant chemotherapy with the methotrexate, vinblastine, doxorubicin, cisplatinum regimen is scheduled. To our knowledge, this is the first report in Korea of upper tract urothelial carcinoma of the sarcomatoid type with a vena caval thrombus.

PURPOSE: To evaluate the association of self-reported erectile function and endothelial function using the EndoPAT device. MATERIALS AND METHODS: We prospectively enrolled 76 men (age> or =40 years) after obtaining a complete medical history and a self-reported questionnaire (International Index of Erectile Function-5 [IIEF-5], SEP Q2, Q3). Endothelial function was noninvasively measured with an EndoPAT 2000, recorded as the reactive hyperemia index (RHI), and analyzed according to the patients' baseline characteristics. RESULTS: The mean patient age and IIEF-5 score were 62.50+/-8.56 years and 11.20+/-6.36, respectively. In comparing the RHI according to erectile dysfunction (ED) risk factors, the RHI was significantly lower in older subjects (p=0.004). There was no difference in the RHI according to age, body mass index, waist circumference, obesity, smoking habit, or other comorbidities. When the subjects were divided into four groups according to the severity of ED, no statistical differences in the RHI value were found among the groups. There was no difference in IIEF-5 according to the RHI when categorized according to the normal cutoff value or quartile ranges. The second subdomain of IIEF-5 (erection firmness) was significantly correlated with the RHI value (R=0.309, p=0.007); however, this was not the case with the other IIEF-5 subdomains. Self-assessment showed a tendency toward a negative correlation with the RHI value (R=-0.202, p=0.080). CONCLUSIONS: The role of endothelial function measurement by the EndoPAT in the evaluation and management of ED patients remains inconclusive. However, further studies are needed to validate the role of endothelial function measurement, by the EndoPAT or any other device.
