Of the 11 advanced bladder cancer patients who received M-VAC (Methotrexate, Vinblastine, Doxorubicin and Cisplatin) combination chemotherapy, complete and partial remission were observed in 63.6%. Of the 17 advanced bladder cancer patients who received MAC (Methotrexate, Doxorubicin and Cisplatin) combination chemotherapy, complete and partial remissions were observed in 17%. Complete remission was achieved in 18.2% of the patients clinically, pathologically in M-VAC group and 5.9% in MAC group. Partial remission was occurred in 46.5% of the patients in M-VAC group and 41.2% in MAC group. All metastatic sites including the bone and liver, lung were well responded in M-VAC group, but poorly responded in MAC group. Toxicity was significant but tolerable.

PURPOSE: Apoptosis is mediated by apoptosis-specific genes, certain oncogenes and tumor suppressor genes. Caspase-3, a group of cysteine proteases, ier in cases with intermediate (Gleason score 5-7) and high-grade (Gleason score 8-10) PCA than cases with BPH and low-grade PCA (Gleason score 2-4).

BACKGROUND: The large volume of blood products are required during orthotopic liver transplantation. Any preoperative and intraoperative factors may influence the intraoperative blood products usage. METHODS: We retrospectively reviewed the demographic information, coagulation screens, thrombelastographic variables, and intraoperative blood requirements in 952 adult patients, who underwent orthotopic liver transplantation at the University of Pittsburgh Medical Center between January 1992 and December 1995. A preoperative coagulation abnormality score (CAS) was calculated by assigning one point of each abnormal result of the coagulation tests (PT, aPTT, platelet count) and thrombelastographic variables (reaction time, alpha angle, maximal amplitude, clot lysis index). Intraoperatively, blood products and pharmacologic coagulation therapy were administered based on thrombelastographic and hemodynamic data. RESULTS: Underlying liver disease, retransplantation one month after the first transplantation, poor preoperative coagulation profiles were predictive of intraoperative blood usage. Age, preoperative PT >15 sec, and CAS were not predictive of intraoperative blood usage. The severe fibrinolysis during operation occurred. More blood products were required in patients with severe fibrinolysis. CONCLUSIONS: The understanding of preoperative and intraoperative factors affecting blood product requirements can help the management of blood component therapy during liver transplantation.

Purpose: This study aims to evaluate the incidence and management of venous ruptures after percutaneous transluminal angioplasty (PTA) for dysfunctional arteriovenous (AV) access. Materials and Methods: From January 1998 to December 2015, 13506 PTA, mechanical thrombectomy, and thrombolysis procedures were performed in 6732 patients. The venous rupture rate following PTA was obtained, and access circuit primary patency (ACPP) was compared according to the etiology (PTA, thrombotic occlusion, and treatment type) of the venous rupture present. Results: Venous rupture developed in 604 of the 13506 procedures. Venous ruptures were more frequent in female, AV graft cases, and in cases accompanied by thrombosis. Balloon tamponade was performed in 604 rupture cases, and stents were deployed in 119 cases where contrast extravasation and flow stasis persisted. ACPP was significantly better in the non-ruptured AV access circuits than in the ruptured group. However, AV access type and thrombosis was not associated with primary patency. In ruptured cases, ACPP is 8.4 months for prolonged balloon tamponade and 11.2 months for bare-metal stent insertion, showing statistically significant difference. Conclusion Balloon tamponade and bare-metal stent placement are effective treatment for PTA-induced venous ruptures. In particular, stent placement showed a similar ACPP to that of non-ruptured AV access circuits.

Although metastatic renal cell carcinoma is not uncommon, metastases to the ureteral stump and bladder are very rare. A 69-year-old woman who had undergone radical nephrectomy because of right renal cell carcinoma about 8 years ago, visited our hospital for evaluation of painless gross hematuria. Histologic examination of the removed ureteral stump and bladder specimen demonstrated metastatic renal cell carcinoma. We report a case of renal cell carcinoma with metastases to the ureteral stump 5 years after radical nephrectomy and bladder 8 years after radical nephrectomy.

This study was aimed to investigate the effects of indomethacin on physiologic root resorption and to examine the dental pulp and tissue changes around the resorbing teeth. 13-14 week old six mongrel dogs were divided into 3 groups; two experimental groups administered indomethacin 2 mg/kg/day and 8 mg/kg/day orally two times a day for 14 days respectively, and control group administered a placebo. The deciduous incisors showing root resorption were selected, fixed for 24 hrs in 10% formalin solution, demineralized in 10% EDTA solution, invested in paraffin and sectioned in 5 micrometer thick sections. The preparations were stained with H and E staining and Masson's trichrome staining and examined under the light microscope. Observation revealed that deciduous root resorbing tissue resembles inflammatory tissue and accompanies bone remodelling. The dental pulp was normal except the area near root resorption, well organized columnar odontoblasts layer under the predentin, and the odontoblasts near root resorption were cuboidal or flat cells in the disrupted layer under the predentin. Indomethacin administered group showed a partial decrease in the number of odontoclasts and nucleus. But there was no sign of pulp change by indomethacin. These results suggest that indomethacin inhibits recruitment of odontoclasts partially and that of osteoclasts more, and so when it is administered for long periods, deciduous root resorption can be delayed and eruption of the successor can be delayed for a short period.
