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 $57.9{\pm}11.0$ (range: $23{\sim}78$) 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.

Core muscle is the most crucial for rehabilitation of patients with musculoskeletal and nervous problem, there is pain, imbalance and functional movement disorder of upper and lower extremities. In this study, low-frequency electrical stimulator was developed for the purpose increasing the activity of rectus abdominis (RA) and the thickness of transverse abdominis (TrA), internal obliquus abdominis (IO), and external obliquus abdominis (EO). Fifteen female in their 20's was divided into a experiment groups (traditional electrical stimulation group, developed electrical stimulation group) and control group. Low-frequency electrical stimulation was performed in experimental groups for 4 times a week, 4 weeks. The muscle activities (RA) by EMG and muscle thickness (TrA, IO, EO) by Ultrasonogrphy imaging were measured, respectively. In the result, the muscle activity of RA and muscle thickness of TrA and EO were significantly increased at developed electrical stimulation group (p<.05). Therefore, the developed low-frequency electrical stimulation is useful for rehabilitation with CNS and PNS subjects.

We report the radio-frequency ablation technique applied on an osteoid osteoma under CT guide and review other new methods of treatment for the osteoid osteoma. An 18-year-old boy with an osteoid osteoma at the left proximal tibia, which was visible at plain film and MRI. He was treated by the percutaneous radio-frequency ablation technique under CT guide after a needle biopsy. He is free from any symptom and able to do daily activities. So, we proposed that the percutaneous radio-frequency ablation technique under CT guide is the effective and safe treatment method for an osteoid osteoma.

Mesenchymal chondrosarcoma is very rare and mostly occurs in lower extremity, especially femur, head and face, and pelvis in order. An eleven-year old male patient suffered from left heel pain for several months and underwent biopsy at another hospital. A Malignant bone tumor was suspected, so the patient was transferred to our hospital. We reviewed the outside pathologic slide, which revealed the diagnosis of mesenchymal chondrosarcoma. It was treated by a below knee amputation. Three months later, a chest computed tomography (CT) revealed multiple metastatic nodules in both lungs. All metastatic nodules were surgically excised and the patient received postoperative chemotherapy. As far as our knowledge, mesenchymal chondrosarcoma in the calcaneus is the first case in the world. Thus, we report a case of mesenchymal chondrosarcoma in the calcaneus with thorough review of documents.

Cervical spondylomyelopathy (CSM) is rarely identified in small-breed dogs. Two neutered female Pekingese dogs (less than 5 kg of body weight) with primary complaints of neck pain and paretic gait were presented. These cases were diagnosed as CSM secondary to vertebral instability through cervical survey radiography, myelography, computed tomography (CT) and CT-myelography. The combinatory treatments of ventral slot decompression, cancellous bone graft and external coaptation were performed. Clinical condition of both dogs remarkably improved and no complications or recurrence occurred following the surgical procedures. In small-breed dogs with CSM, the combination of decompression through ventral slot and stabilization through bone fusion is an effective treatment.

Tropical fire ant, Solenopsis geminata (Fabricius) is distributed over the tropical and temperate areas. It is a polyphagous pest attacking to various plant and causes the pain to the people doing outdoor work. So it is known for a hygienic pest to human being, especially the people doing outdoor activities. It can cause severe pain to human, even with just a bite. Of particular concern is the possibility of its settlement in this country, if it invade to the farmlands and/or forests of Jeju Island and southern part in Korea. It is listed as a regulated pest in Plant Quarantine Act of Korea. This ant is usually imported through a ship and early settled in the port area where it is already distributed. Recently its distribution is rapidly spreading into Southeast Asia and southern part of China. In Korea, it was detected the one time in 1990s, but was detected the ten times from 2000 to 2006 by an imported plant quarantine process. Therefore, we would like to provide some information on the species, including morphology, distribution, host plant, damaged symptom and its general bionomics, which will be useful data for plant quarantine process and control.

Adenomatoid odontogenic tumor (AOT) is a rare benign odontogenic jaw lesion. It usually occurs in the anterior maxilla and is mostly related to impacted canines in teenagers. A 3-year-old girl was referred from a local dental clinic due to delayed eruption of the right primary mandibular 2nd molar. There was no history of pain or swelling. Radiography revealed a large radiolucency lesion with radiopacities around the unerupted right primary mandibular 2nd molar. Surgical enucleation with extraction of the right primary mandibular 2nd molar and surgical biopsy were performed. Based on the clinical and radiological findings, this lesion was defined as an ameloblastic fibro-odontoma which often develops in the mandible of adolescents. However, this lesion was diagnosed as AOT from the results of the histological examination. This report aimed to present a rare case of AOT in the posterior mandibular area in a very young patient.
