The treatment of massive bone and soft tissue defect in the lower leg has a high complication rate of nonunion, chronic infection, and amputation without well-vascularized tissue coverage of the open fracture. Despite adequate free soft tissue coverage, massive skeletal defect may result in segmental bone defects, angulation deformity, and limb length discrepancies. In the last decade, major advances have occurred in the Ilizarov method of distraction osteogenesis in lower leg salvage as a delayed procedure or simultaneous distraction after free-tissue transfer. The authors have performed Ilizarov transport in conjunction with muscle and musculocutaneous flap coverage in nine cases of lower leg salvage. The flaps consist of rectus, gracilis, latissimus dorsi, parascapular, and serratus muscle or musculocutaneous fashioning using ipsilateral or contralateral pedicle in consideration of vessel condiation. Revision, recorticotomy and flap elevation were also used as a secondary procedure for satisfactory results. The conclusions, were as follows: 1) Multidisciplinary team approach with conjoining departments at the time of preoperative evaluation, postoperative care and rehabilitation care; 2) Muscle flap covered with split-thickness skin graft was preferred to musculocutaneous flap; 3) To reduce the total reconstructive period, simultaneous free tissue transfer with Ilizarov distraction should be considered.

Primary leptomeningeal melanomas(PLMs) are rare aggressive central nervous system(CNS) tumors without systemic foci. It can be very difficult, however, to clearly distinguish PLMs from those that have metastasized. We report a case of malignant leptomenigeal melanoma occurring in the right temporal convexity of a 77-yearold woman. Almost all malignant CNS melanomas in the old are secondary to the cutaneous melanoma and can cause diverse neurological manifestations; certain clinical findings of the presented case-namely, the patient's age, vague neurologic findings and absence of cutaneous lesions -are therefore interesting. Thorough clinical checkups, including whole-body bone scan, whole spine MRI, abdominal ultrasound, and tumor marker studies to find extracranial lesions revealed no abnormalities. Based on these clinical findings, we suppose-though are not certain-that the tumor of the presented case is a PLM.

An indirect porcine epidemic diarrhea (PED) virus (PEDV) enzyme-linked immunosorbent assay (ELISA) was compared with the serum neutralization (SN) test by testing 46 samples from experimentally infected sows, 73 samples from naive sows, and 1, 024 field sow samples from 48 commercial swine farms of undefined PED status. The SN test and the ELISA were performed using PEDV, KPEDV-9 strain. Viral proteins as a coating antigen of PEDV ELISA were extracted from the cytoplasm of PEDV-infected Vero cells using a non-ionic detergent, Triton X-100, and a simple protocol of PEDV ELISA was followed. The presence of antibodies in these experimental samples was confirmed by SN and ELISA in which the sensitivity of the ELISA was 89.1%, and the corresponding specificity was 94.5%. On testing 1, 024 field samples, an overall agreement of 84.2% was generated between the SN and ELISA. This study demonstrates that the PEDV ELISA is a useful serodiagnostic screening test at herd level for detecting swine antibodies against PEDV.

OBJECTIVE: On-line hemodiafiltration (OL-HDF) is a method that combines diffusive and convective solute transport component. OL-HDF provides improved solute clearance for both low-and large molecular-weight uremic toxins by enhancing convective clearance through highly permeable membranes. The aim of this study is to evaluate the effect of OL-HDF on oxidative stress and beta2-microglobulin (beta2-MG) in comparison with high-flux hemodialysis (HF-HD). METHODS: Twenty-one patients on thrice-weekly low-flux hemodialysis (LF-HD) for at least 6 months were studied. Every patient underwent OL-HDF and HF-HD for four weeks, respectively. There were 2 weeks of wash-out period in which patients were treated with LF-HD, between different treatment periods. Predialysis and postdialysis solute (creatinine, BUN, phosphate, beta2-MG) concentrations were measured in the serum. In addition, predialysis solute (MDA, TAC, hsCRP) concentrations were measured. RESULTS: The urea reduction ratio (64.2+/-14.5 vs. 60.1+/-11.2%), Kt/V (1.4+/-0.2 vs. 1.3+/-0.3), beta2-MG reduction ratio (53.8+/-9.7 vs. 44.3+/-8.7%) and beta2- MG clearance (120.7+/-33.4 vs. 92.7+/-17.6 mL/min) were significantly higher in patients treated with on- line HDF compared with those treated with HF-HD. After 4 weeks of treatment, predialysis serum MDA levels were significantly lower in patients treated with OL-HDF compared with those treated with HF-HD (1.04+/-0.26 vs. 1.19+/-0.25 umol/L). After 4 weeks of treatment with 2 different dialysis modes, predialysis serum beta2-MG (3.7+/-1.0 vs. 2.2+/-0.4 mg/ dL), MDA (1.19+/-0.21 vs. 1.04+/-0.26 umol/L), TAC (265.9+/-21.1 vs. 290.2+/-23.9 umol/L) and log hsCRP (0.07+/-0.51 vs. -0.23+/-0.62) levels were significantly improved compared to the baseline in OL-HDF patients. However, for HF-HD patients, only predialysis serum beta2-MG level at 4 weeks was significantly lower than baseline (3.8+/-1.0 vs. 2.5+/-0.4 mg/dL). CONCLUSION: This study shows that OL-HDF has been significant increase in oxidative stress and inflammatory marker removal compared to HF-HD.

PURPOSE: International Prognostic Index Model (IPIM) in aggressive non-Hodgkin's lymphoma was published and accepted generally as a better predictive model for prognosis. This study was undertaken to identify prognostic factors of aggressive non- Hodgkin's lymphoma and usefulness of IPIM in Korea. MATERIALS AND METHODS: Previously untreated, pathologically proven 226 aggressive non-Hodgkin's lymphoma patients who were treated with CHOP or COP-BLAM V between 1986 and 1995 in Seoul National University Hospital were evaluated for clinical features predictive of overall survival. RESULTS: Complete response (CR) was reached in 76% of all patients. With a median follow-up of 62 months, 5-year disease free survival of complete reponders was 67% and 5-year overall survival of all patients was 54%. In a univriate analysis, age, ECOG performance status, Ann Arbor stage, histologic subtype, bone marrow involvement, bulkiness, serum LDH level and number of extranodal involvement were significant prognostic factors for CR and survival (p<0.05). Of these, by multivariate analysis, age(RR 0.4, 95% CI 0.2~0.9) alone was a independent prognostic factor for CR. For disease free survival, no independent prognostic factor was found. For overall survival, Ann Arbor stage (RR 1.7, 95% CI 1.1~2.8), age (RR 1.7, 95% CI 1.1~2.6), Histologic subtype (RR 1.7, 95% CI 1.1~2.8), serum LDH level (RR 1.7, 95% CI 1.1~2.6) and bone marrow involvement (RR 1.8, 95% CI 1.0~3.1) were independent prognostic factors. According to risk group of IPIM, 5-year overall survival rate was 72% in low risk group, 46% in low intermediate risk group, 32% in high intermediate risk group, respectively, and median survival of high risk group was 12 months (RR 1, 2.3, 4.3, 6.4 respectively). CONCLUSION: IPIM is a useful model for identifying poor prognostic groups in aggressive non-Hodgkin's lymphoma.
