A randomized, prospective study was conducted between October, 1994 and April, 1996 to compare the efficacy and safety of warfarin (group I) with dextran (group II) for the prevention of DVT after hip arthroplasty. 109 cases in 106 patients were included in the study. There were 60 cases in group I and 49 cases in group IL Risk factor for DVT were analysed before surgery and prophylactic modalities were performed. Color doppler was performed to all patients by one muskuloskeletal radiologist on 5th 8th post operative day and on 6 weeks after operation. DVT occurred in ten ( 16.6% ) of the 60 patients in group I, six ( 12.2% ) of the 49 patients in group II. but, this difference was not significant ( p= 0.582 ). Statistical analysis for the risk factors of age, sex, operation time, anesthetic method and operation method were performed and there were no statistical difference. Only statistical significance was a higher rates of DVT in cemented hip arthroplasty (p=0.028). There were seven proximal thigh DVT and nine calf DVT. We confirmed with sequential color doppler image that all cases of DVT except two complicated cases were resolved within 8 weeks after treatment: one case was expired for the reason of PE, and the other case had thigh hematoma during the treatment with warfarin. We could detect only one case of late onset DVT.

OBJECTIVE: 6-Gingerol, one component of ginger (Zingiber officinale) compound, has been known to possess anti-inflammatory, analgesic, anti-emetic, and anti-cancer effects. In this study, the apoptotic ability of 6-gingerol was investigated in human prostate cancer cells. METHODS: 3-(4,5-Dimethylthiazol-2-yl)- 2,5-diphenyl-tetrazolium bromide (MTT) assay, flow cytometry, and western blot analysis were done in LNCaP human prostate cancer cell lines treated with the various doses of 6-gingerol for the different durations of drug exposure. RESULTS: 6-Gingerol in doses ranging from 100 to 300 microM induced dose- and time-dependent inhibition of cell viability in prostate cancer cells by using MTT assay. Maximal inhibition of cell viability was observed at 300 microM of 6-gingerol for 48 hours treatment in LNCaP cells. 6-Gingerol at the dose of 100 microM did not produce any significant change in apoptotic cells in flow cytometry analysis. However, significant increase in sub-G0/G1 phase was observed in cells treated with 200 and 300 microM of 6-gingerol. Any significant cell cycle arrest was not induced by 6-gingerol. In western blotting analysis, expression of caspase-3 was not evident in cells treated with 6-gingerol for 24 hours. However, 48 hours treatment with 6-gingerol altered the expression of caspase-3 in LNCaP cells. Expression of cleaved poly showed the dose-dependent fashion in both 24 hours and 48 hours treatment of 6-gingerol. CONCLUSION: These observations suggest that 6-gingerol may induce apoptosis in LNCaP human prostate cancer cells.

PURPOSE: Predicting the change in breast size for a specific patient's need is a challenging problem in breast augmentation. We intended to investigate the post-augmentation degree of breast size according to the size of cohesive silicone gel implant. METHODS: To predict post-augmentation breast size, we measured 100 patients' pre-and postoperative 3 month's bust circumference. All patients were performed by total subfascial breast augmentation with moderate profile cohesive silicone gel implant through areolar omega (transareolar-perinipple) incision. RESULTS: According to this study, each additional one pair of 100mL in implant size yielded an approximate 1.5cm increase in bust circumference(p=0.006). CONCLUSION: From this result, we conclude that each additional one pair of 100mL in implant volume yielded about 1.5cm increase in bust circumference. Although this result may not be applied to every patient, we believe that it yields a practical chart that can help to predict the amount of increase in breast size with the use of cohesive silicone gel implant of a specific size preoperatively.

PURPOSE: The significance of constitutive apoptosis in the development and progression of transitional ceil carcinoma of the bladder has yet to be investigated. The wild type p53 gene is known to play a significant role in apoptosis. Therefore, mutation of p53 gene, which correlates closely with p53 protein overexpression, would be predicted to limit apoptosis. We evlauated the prognostic significance of apoptosis and the relationship between apoptosis and mutant p53 overexpression in transitional cell carcinoma of bladder. MATERIALS AND METHODS: The extent of apoptosis was determined by TUNEL(terminal deoxynucleotidyl transferase mediated biotinylated deoxyuridine-triphosphate nick end labeling) stain in 64 paraffin embedded tissue of primacy transitional cell carcinoma specimens. Also, the level of p53 overexpression was determined immunohistochemically on the same tissue. RESULTS: Although the incidence of apoptosis increased with increasing tumor grade, the difference in indices between grade II and grade III failed to reach statistical significance. The mean apoptotic index(AI) of grade I tumors was significantly lower than that of grade III tumors(p=0.0023). The apoptotic index was not related to p53 overexpression, T(tumor)-category, growth type of tumors and also there was no significant difference in disease-free survival between the bladder tumors with high as opposed to low apoptotic index. CONCLUSIONS: The results show that AI is related to histological grade in transitional cell bladder tumor, while AI hardly has any independent prognostic significance.

Bilateral fibroepithelial polyps of the ureter are scarcely seen benign mesodermal tumor that occurs most often at the proximal ureter. Most patients present with either hematuria due to necrosis at urethral polyp of flank pain secondary to partial ureteral obstruction. The Diagnosis may be established with intravenous pyelography, retrograde pyelography, ureteroscopy and CT. Local resection is the treatment of choice. We report a case of bilateral fibroepithelial polyps of the ureter with a brief review of literatures.

Breast reconstruction with free TRAM flap is a common procedure. However patients with abdominal scars can be confronted with a challenging problem in performing flap reconstruction. The inadequate blood supply around the scar can result in various skin complications in flap or donor site, but there are no reported guidelines in our country. From May 1999 to March 2003, a total of 38 breast reconstructions using free TRAM flaps were performed for 37 patients, of whom 12 had abdominal scars from previous operations; 7 had midline vertical scars and 4 had low transverse scars from Cesarean section or total hysterectomy, 3 had right lower quadrant oblique scars from appendectomy (2 also had transverse scars from Cesarean section). We attempted to minimize flap and donor site complications by modifying classic free TRAM flap designs and procedures according to the characteristics of the abdominal scars and performed periodic follow-up observations of flaps and donor sites for presence of complications and also gave surveys for patient satisfaction on the reconstructed breast. All 38 patients underwent successful breast reconstructions with neither skin complications around the scar nor flap loss and 96.4% patients reported being very satisfied or satisfied with the results.

PURPOSE: Recently, a percutaneous aspiration with sclerotherapy has become the treatment of choice for the symptomatic, large, and simple renal cyst because of its minimal invasiveness and high effectiveness. The recurrence rate of a percutaneous aspiration only, was reported to range from 30 to 70%. This study was performed to evaluate the effects of percutaneous aspiration with sclerotherapy. MATERIALS AND METHODS: The results of the treatment in 36 cases of simple renal cysts from October 1993 to December 1999 were evaluated. The symptoms associated with simple renal cysts were: flank pain or discomfort (50%), none (47.2%) and a palpable mass (2.8%). The simple renal cysts were treated with a percutaneous aspiration only in 6 cases, a percutaneous aspiration with sclerotherapy using 99% ethanol in 21 cases or a 10% minocycline solution in 9 cases. All patients were followed up by ultrasound for 6 to 56 months (mean 18 months). RESULTS: Complete collapse, and partial collapse rate of the renal cysts were 1/6 (16.7%), 2/6 (33.3%) in the aspiration only group, 6/21 (28.6%), 14/21 (66.7%) in the 99% ethanol group and 3/9 (33.3%), 4/9 (44.4%) in the 10% minocycline solution group, respectively. CONCLUSIONS: Therefore, a percutaneous aspiration with sclerotherapy using either 99% ethanol or 10% minocycline solution appears to be an effective way to the prevent re-accumulation of cystic fluid. However, the success rates in the percutaneous aspiration with sclerotherapy using 99% ethanol and 10% minocycline solution were not significantly different.

We report a case of renoduodenal fistula resulting from papillary renal cell carcinoma. A 72-year-old woman presented with nausea, diarrhea and abdominal discomfort. Abdominal CT, UGI and sinography revealed fistula between the right renal mass and the duodenum. Radical nephrectomy and duodenal wedge resection was performed and a friable mass with a fistula between the lower pole mass of the right kidney and second portion of the duodenum was found. Histologic evaluation for renal mass showed papillary renal cell carcinoma. We describe this case and review the previously reports of renoduodenal fistulae.

Purpose: The transforming growth factor-beta (TGF-beta) is a peptide that has diverse biologic actions in human tissue and is thought to contribute to tumor development and progression. Increased TGF-beta1 levels were found in several types of malignant tumors. TGF-beta1 expression in RCC and adjacent normal kidney tissues was examined to determine the TGF-beta1 in renal cell carcinoma (RCC). MATERIALS AND METHODS: The TGF-beta1 protein levels in cancer and a normal portion of a specimen were analyzed in 61 radical nephrectomized clear cell type RCC by an enzyme-linked immunosorbent assay (ELISA), with the results compared with the clinicopathological characteristics. Immunohistochemical staining was performed to localize their expression. RESULTS: Compared with non-tumor kidney specimens, primary renal cell carcinoma demonstrated a significantly higher TGF-beta1 protein level (p<0.001). There were significant differences in the TGF-beta1 level among the histological grade (p<0.01). The tissue TGF-beta1 level was the highest in T4 stage, but there was no statistical significance between the T stages. Immunohistochemical analysis demonstrated that TGF-beta1 was localized to the tumor cytoplasm and their intensity reflected the protein expression level in these tissues. CONCLUSIONS: These results suggest that enhanced TGF-beta1 expression contributes to carcinogenesis and tumor progression in the later stages of renal cell carcinoma.
