PURPOSE: The result of cementless total knee arthroplasty with posterior cruciate ligament retention in rheumatoid arthritis patients was evaluated. MATERIALS AND METHODS: Thirty patients (fifty knees) followed up after cementless total knee arthroplasty with posterior cruciate ligament retention was evaluated clinically and radiologically. Average follow up was 9.2 years(5.1~14.3). RESULTS: The mean HSS knee score improved from 47.4 preoperatively to 81.8 postoperatively, and the mean range of motion of 89.7 degrees preoperatively to 101.2 degrees postoperatively. The mean tibiofemoral angle was 4.9 degrees valgus. Posterior instability was observed in 1 case(2%) at the most recent follow up. Radiolucent line was observed in 41 cases(82%), and osteolysis was observed around tibial component in 13 cases(26%), and around femoral component in 4 cases(8%). Eight cases(16%) of revision was due to 1 case of aseptic loosening and osteolysis each, and the other due to polyethylene wear of patellar or tibial component. CONCLUSION: Although there are osteopenia in rheumatoid arthritis compared to osteoarthritis, cementless total knee replacement with posterior cruciate retention showed stable fixation. However, the new method for initial fixation of tibial component is needed because osteolysis around tibial component tended to start around cancellous screws.

PURPOSE: To evaluate the effect of obesity on perioperative morbidity following total hip arthroplasty in patients with severe osteoarthritis. MATERIALS AND METHODS: Between April 1987 and April 2007, 272 patients with severe osteoarthritis underwent total hip arthroplasty. One hundred seventeen patients were obese (body mass index, BMI> or =25 kg/m2), and 155 were not obese (BMI<25 kg/m2). Through retrospective medical record research we were able to determine length of hospital stay, operation time, total blood loss and replacement, and surgical and medical complication rates for the two groups. RESULTS: The obese and non-obese groups were similar in terms of length of hospital stay, operation time, total blood loss and replacement, and surgical complication rate (p>0.05). However, the medical complication rate was significantly higher in the obese group compared to the non-obese group (4.3% vs. 0.6%, p<0.005). CONCLUSION: In severe osteoarthritis patients undergoing total hip arthroplasty, obesity (BMI> or =25 kg/m2) has no observable effect on perioperative morbidity in terms of length of hospital stay, operation time, total blood loss and replacement, or surgical complication rate, but is associated with a higher medical complication rate.

Since Steeg, et al.(1988) identified NM23/NDP kinase as non -metastasis gene, other multiple functions of have reported. One of them, Postel, et al.(1993) suggested that transcription factor PuF, being encoded by NM23 -H2/NDP kinase gene, interacts with nuclease hypersensitive element located upstream of the c -myc gene. C -myc amplification and activation can be present in squamous cell carcinoma of the head and neck as well as in an increased metastatic propensity for individual tumor. To clarify the role of NM23/NDP kinase on c -myc expression, comparison of these two gene expressions in cell lines was done. No direct correlation of expression kinetics was found. A plasmid containing human c -myc fragment was cloned upstream of chloramphenicol acetyltransferase (CAT) gene. When murine melanoma cell line was cotransfected with a murine NM23 -M2 including expression vector and c -myc CAT, CAT activity was elevated, while no change of CAT activity was found in the cotransfectant of human NM23 -H2 and c -myc CAT. Data suggest that murine NM23 -M2 gene transactivates c -myc gene indirectly with a cellular factor in murine cell line which dose not work with human NM23 -H2 gene. Additionally, we found same kinetics of NM23 -H2/NDP kinase and c -myc expression change correlated with proliferation of PLC/PRF/5 which was induced by HGF.

Primary papillary serous carcinoma of the peritoneum(PPSCP) is vere rare. It has been suggested that PPSCP derives from embryonal coelomic epithelium with m llerian ducts potential. PPSCP can develop from a single or multicentric focus. The clinical and histologic disease entities are similar to those of primary papillary serous carcinoma of the ovary, but PPSCP involves the ovarian surface only minimally(microscopic disease) or spares the ovaries entirely. We have experienced a case of primary papillary serous carcinoma of the peritoneum and report this case with brief review of the concerned literature.

Enterovesical fistula is a relatively rare disease and usually caused by primary intestinal disease (diverticulitis, colon cancer and inflammatory bowel disease including Crohn's disease etc.). We experienced a rare case of ileocolovesical fistula caused by Crohn's disease. The 34 year old man had had chronic dysuria, lower abdominal pain and turbid urine for 3 years. Contrast studies including cystography, small bowel series, barium enema and abdominal Of showed ileocolovesical fistula. Small bowel segmental resection, Hartmann's colostomy and suprapubic cystostomy were performed. Histological examination of operative specimen showed a granulomatous inflammation caused by Crohn's disease. Our case suggests that Crohn's disease may be a rare cause of enterovesicalfistula in Korean.

PURPOSE: To evaluate the morphologic differential diagnosis of benign and malignant ductal breast tumors, as seen on US. MATERIALS AND METHODS: US findings in 29 pathologically proven cases of ductal breast tumor were retrospectively reviewed. All patients were female and their mean age was 42 years. Nineteen tumors were benign and ten were malignant, and all ductal or cystic lesions showed solid masses. According to the location of the mural nodule, we classified the sonographic appearance of these tumors into three types : intraductal, intracystic and amorphic. The intraductal type was divided into three subtypes: incompletely obstructive, completely obstructive and multiple mural nodules. For the intracystic type, too, three subtypes were designated : the intracystic mural nodule (mural cyst), intracystic mural nodule with the duct (mural cyst+duct) and intracystic multiple mural nodules. The amorphic type is defined as an atypical ductal tumor with the mural nodule extending into adjacent parenchyma. RESULTS: The margin of the duct or cyst was smooth in 68.4% of benign, and irregular in 90% of malignant ductal tumors. Internal echogeneity of the duct or cyst usually showed homogeneity in both benign and malignant tumors. 73.7% of tumors connecting the duct were benign and 50% were malignant. In benign tumors, 52.6% of mural nodule had an irregular margin, while in malignant tumors, the corresponding proportion was 100% ; both types usually showed heterogeneous hypoechogeneity. Among benign tumors, the most common morphologic type was the intraductal incompletely obstructive subtype (36.8%) ; among those that were malignant, the amorphic type was most common, accounting for 40% of tumors. No amorphic type was benign and no incompletely obstructive subtype was malignant. CONCLUSION: When ductal breast tumors are morphologically classified on the basis of sonographic findings, the intraductal incompletely obstructive subtype suggests benignancy, and the amorphic type, malignancy. The morphologic classification of ductal breast tumors based on sonography is therefore useful for the differential diagnosis of benignancy and malignancy.
