It has been claimed that CNS lymphoma, a rare neoplasm accounting for only a small fraction of malignant brain tumors, occurs with increasing frequency in immunologically normal as well as immunocompromised individuals. We investigated the prognostic value of Ki-67 index, p53, and bcl-2 oncoprotein expression in relation to the clinicopathological parameters in the primary CNS lymphoma patients. The tumors were graded by Kiel classification and the Working formulation and included 33 high-grade, 4 intermediate-grade, and 5 low-grade lymphomas. The phenotype was determined in 38 cases: 30 were B cell type and 8 were T cell type. All cases displayed variable degrees of nuclear Ki-67 staining from 1.0% to 92.0% (mean 51.1%). A highly significant correlation was established between the proportion of Ki-67 positive cells and the classification into grades (p=0.0002) and phenotypes (p=0.0002). Overexpression of p53 and bcl-2 protein was found in 37.1% and 51.4% of 35 patients, respectively. And p53 expression was significantly increased in B cell type (p=0.02). On Kaplan-Meier survival curve, the phenotype, grade of tumors, and p53 and bcl-2 protein expression were not correlated with overall survival. On multivariate analyses, overall survival was independently influenced by Ki-67 index. In conclusion, it is suggested that Ki-67 proliferating index is the most important marker for predicting biologic behavior of the primary CNS lymphoma.

Juvenile granulosa cell tumor is rare but one of the common congenital testicular neoplasms. Although histological features are typical of its ovarian counterpart, testicular juvenile granulosa cell tumor has a distinctly different clinical presentation. We report a case of juvenile granulosa cell tumor arising in the cryptochid testis of a 4-day-old newborn. A 6 5 5 cm sized multilocular cyst containing thick, mucinous fluid was found in the peritoneal cavity. The external surface of the cyst was smooth and the septae were relatively thin. The cyst consisted of numerous mucin-filled, cystic follicles lined by cells having vacuolated cytoplasm and round to oval dark nuclei without grooves. Cells resembling granulosa cells of an ovarian follicle were also observed in the intervening stroma forming irregular solid nests.

PURPOSE: To compare the efficacy and availability of foot pump and active ankle exercise for preventing deep vein thrombosis after total knee arthroplasty with hemodynamic evaluation using a color doppler duplex ultrasonography. MATERIALS AND METHODS: Thirty-six patients who underwent total knee arthroplasty between Oct. 2005 and Apr. 2006 were enrolled in this study. Retrospective analysis of 36 patients(Group 1 - foot pump after TKA, 18; Group 2-passive ankle exercise, 18) was conducted and all patients underwent color doppler duplex ultrasonography preoperatively and postoperative 7 to 14 days at femoral, popliteal and calf vein and the hemodynamic status was assessed. RESULTS: The mean baseline velocity was decreased postoperatively in both group, at all veins, but the mean peak velocity was increased only in Group. In Group 1, mean flow ratio was increased, but in Group 2, mean flow ratio was decreased except femoral vein. There were significant differences between Group 1 and Group 2(p<0.05). CONCLUSION: This study demonstrated that foot pump may be more effective than active ankle exercise in preventing postoperative deep vein thrombosis due to more increased venous flow rate and foot pump may be more compliable than active ankle exercise due to less painful, more convenient, so foot pump can be one of the available method for preventing DVT after total knee arthroplasty.

Macrostomia is a relatively rare malformation. There have been many surgical methods for the correction of macrostomia. The old method, a simple straight line closure , did not include reconstruction of the orbicularis oris muscle. Postoperatively, a depressed scar and severe contraction on the cheek were found, especially with animation. As a result, many authors have known that reconstruction of the orbicularis oris muscle was very important to avoid a depressed scar for the correction of macrostomia. The tendency toward lateral displacement of the reconstructed commissure has been attributed to linear scar contraction, and Z-plasty is advocated to prevent this deformity. However, we found that the Z-plasty scar may be conspicuous when the patient smiles. So we performed reconstruction of the orbicularis oris muscle to avoid a depressed scar, and straight line closure to avoid a conspicuous scar. In order to prevent linear scar contracture due to straight line closure, we overcorrected the new commissure. We treated 6 cases of macrostomia form May 1, 1996 to April 30, 1999 using straight line closure and reconstruction of the orbicularis oris muscle. Periods of follow-up were from 12 months to 35 months, with an average of 20,2 months. Every patient was analyzed clinically by ordinary scale method and anthropometrically by the ratio of abnormal distances to normal distances between cheilion and crista philtri. In 3 clinical assessments : symmetry of the commissure was excellent: degree of the scar at rest was good: and degree of depression with animation was excellent. The anthropometrical ratio was 1:1.05. Despite the fact that the linear scars were perpendicular to the minimal skin tension lines, the scars were inconspicuous. The muscle repair provided reconstruction to the modiolus and gave a natural appearance to the commissure, however it did not seem to provide sufficient bulkiness around the commissure. The straight line skin closure and repair of the orbicularis oris muscle provide effective functional and aesthetic reconstruction.
