BACKGROUND: Radiofrequency obliteration and endovenous laser therapy of the greater saphenous vein have recently been introduced as alternative, minimally invasive techniques for the treatment of saphenous vein incompetence. The 7 Fr. VNUS ClosureFAST(R) radiofrequency obliteration system was introduced in Gwang-Ju Veterans hospital. The purpose of this study is to evaluate the efficacy and complications of radiofrequency obliteration using the 7 Fr. VNUS ClosureFAST(R) system. MATERIAL AND METHOD: Between May 2, 2007 and May 31, 2008, we performed radiofrequency obliteration on 90 patients. The number of males was 67 and their mean age was 57.9+/-11.0 (range: 23~78) years old. The patients underwent follow up exams at 3 weeks after the procedures and then every 3 months. The effects of treatment and the complications were reviewed. RESULT: The postoperative complications were ecchymosis (94.4%), pain (27.8%), paresthesia (25.6%), bullous formation (8.9%), edema (6.7%) and phlebitis (2.2%). One patient showed good blood flow after 3 weeks and one patient showed good blood flow after 3 months. The one-year success rate of radiofrequency obliteration in varicose veins was 97.6%. CONCLUSION: Our data showed acceptable operative results and short-term clinical results for treating varicose veins with radio frequency obliteration. Long-term follow-up and comparison of radio frequency obliteration with high ligation and stripping, previous radiofrequency ablation and endovenous laser therapy are needed in the future.

The prevalence of group B streptococcus (GBS) among pregnant women and disease burdens in neonates and adults are increasing in Korea. Colonizing isolates, collected by screening pregnant women (n=196), and clinical isolates collected from clinical patients throughout Korea (n=234), were serotyped and screened for antibiotic resistance. Serotype III (29.8%) and V (27.7%) predominated, followed by Ia (17.0%). Antibiotic resistance was higher among clinical than colonizing isolates for erythromycin (35.1% and 26.9%; P=0.10) and for clindamycin (49.4% and 42.1%; P=0.17). erm(B) occurred in 91.9% of erythromycin resistant isolates, and 84.0% of isolates resistant to clindamycin. Only five isolates (4.2%) resistant to erythromycin were susceptible to clindamycin; by contrast, and unique to Korea, 34% of isolates resistant to clindamycin were erythromycin susceptible. Among these 60 erythromycin-susceptible & clindamycin-resistant isolates, 88% was serotype III, and lnu(B) was found in 89% of strains. Four fifths of the serotype V isolates were resistant to both erythromycin and clindamycin. Further characterization of the genetic assembly of these resistance conferring genes, erm(B) and lnu(B), will be useful to establish the clonal lineages of multiple resistance genes carrying strains.

Posttransplant lymphoproliferative disorders (PTLD) is an infrequent but serious complication of transplantation. Previous studies have suggested the terms of reference, "early PTLD" (referring to PTLD that occurs within 1 year of transplantation) and "late PTLD" (PTLD that occurs after 1 year). Early PTLD generally involves a single organ or nodal region and often responds favorably to a decrease in immunosuppression. Late PTLD tends to be disseminated, responds less frequently to a decrease in immunosuppression, and has a dismal prognosis. We encountered a diffuse large B-cell lymphoma in a 44-year-old man who underwent kidney transplantation over 10 years ago, in 1995. In situ hybridization for Epstein-Barr virus showed positive results in tumor cell. With decreased immunosuppressants and chemotheraphy, he is currently in complete remission.
