Aneurysmal bone cysts are uncommon bony lesions of the spine. Approximately 3-20% of the aneurysmal bone cysts occur in the spine, predominantly in the lumbar region, but they may occur at the any level of the spine. These lesions commonly arise from the neural arch and occasionally invade the pedicle and the vertebral body. The clinical diagnosis of a spinal lesion can be very difficult in the early stages of the disease because specific symptoms and signs are usually absent or only amount to back pain. However, depending on the level of involvement and the extent of neurological compression, a wide variety of neurological symptoms and signs may appear, ranging from mild radicular symptoms to complete paraplegia or tetraplegia. Available treatment options include complete excision or curettage of the lesion with bone graft, but where excision cannot be achieved, low dose radiation or arterial embolization may be used. We report a case of aneurysmal bone cyst in the pedicle of the T10 spine with nonstructural scoliosis of $40^{\circ}$ Cobb's angle which was treated successfully with only curettage of the lesion.

The osteopoikilosis is a rare disorder characterized by multiple radiodensities in the metaphysis or in the epiphysis of long tubular bones. The etiology and pathogenesis remain obscure, generally transmitted as an autosomal dominant fashion. The osteopoikilosis is asympotomatic and it is usually found radiologically as an incidental finding. Our case shows a typical clinical feature of the osteopoikilosis, and the biopsy was done to differentiate other disease from the osteopoikilosis.

Angiosarcoma is a very rare disease of soft tissue sarcoma, and angiosarcoma arising in a region of chronic lymphedema is referred to as Stewart-Treves syndrome. it typically occurs in postmastectomy lymphedema of the arm and sporadically in a lymphedematous leg. The prognosis, even with wide surgical excision and subsequent radiotherapy, is poor. The authors experienced a case of angiosarcoma in a chronically lymphedematous leg which had undergone hysterectomy due to cervical cancer 17 years ago and lymphedema of leg persists for about 16 years. We report a case of angiosarcoma with a brief review of the literature.

Alveolar soft part sarcoma, named by Christopherson in 1952, is a very rare soft tissue sarcoma. It reportedly accounts for 0.5 to 1.0% of all soft tissue sarcoma and no established treatment principle assists it. The relative lack of symptoms makes it easily overlooked and consequently early diagnosis is frequently impossible. Often, the metastasis to the lung or the brain is the first manifestation of the disease. In some cases wide excision is not performed because it is misdiagnosed as a benign tumor. Authors experienced 7 cases of alveolar soft part sarcoma in 20 years and found the ultimate prognosis grave and the treatment not promising. Therefore, the authors recommend the following; 1. Early diagnosis and early treatment are important for successful management of alveolar soft part sarcoma. 2. Preoperative incisional biopsy is necessary for pathologic diagnosis. 3. The recommended treatment modality is a combination of wide excision, chemotherapy and radiotherapy.

Malignant tumor of the pelvic bone has nonspecific symptom and it is not easily detected by physical examination or by radiologic study in early stage, because of its anatomical characteristics. Associated with their variety of disease entity, the treatment of malignant pelvic bone tumor is a problematic point. We have analysed 36 cases of malignant pelvic bone tumors diagnosed at the Severance hospital from 1968 to 1993 to provide a reference for diagnosis and treatment of the malignant pelvic bone tumors. We found that the chondrosarcoma(27.8%) and the osteogenic sarcoma(27.8%) were the most common type of pelvic bone malignancy, and then, in the order of incidence, there were Ewing's sarcoma(16.7%), malignant fibrous histiocytoma(11.1%). There were differences of the age distribution among each diseases and the average age was Ewing's sarcoma 20.5, osteogenic sarcoma 27.2, chondrosarcoma 40.0, malignant fibrous histiocytoma 64.8, respectively. Three of the 5 patients with low grade tumors survived(60%), whereas 3 of the 17 patients with high grade tumors survived(18%). The survival rate of the low grade malignant group was 60%, the high grade was 18%.

Objectives This study is to report a case that has an effective result to oligoarticular type juvenile idiopathic arthritis patient with the oriental medicine treatment. Methods We treated the patient with an oriental medicine and tapered down with the DMARDs and NSAIDs. We followed up the laboratory blood tests every four or five months and throughout the experiment. Results The symptoms of oligoarticular type juvenile idiopathic arthritis were vanished and the patient maintained her good health condition with oriental medicine treatment after discontinued all Disease-Modifying Antirheumatic Drugs (DMARDs) and NSAIDs (Non-Steroidal Anti-Inflammatory Drugs). Her ESR, CRP levels were stable in normal and other blood test results were back to normal range. Her joint mobility and condition was back to normal. Now she is in clinical remission status. Conclusions According to the result, the oriental medicine treatment is considered to be effective on the oligoarticular juvenile idiopathic arthritis and further studies will be needed with more cases.

Recently, the increase in the elderly population due to an aging society has led to a relative increase in senile diseases such as vascular dementia or Alzheimer's disease, and the social burden for rehabilitation has increased. In addition, studies have been conducted for the risk assessment and prevention of musculoskeletal disorders. The purpose of this study is to suggest a system that can be used to help with dementia prevention training by tracking the movement of motion and virtual reality contents for the risk factors of musculoskeletal disorders of the elderly. We propose a training method for preventing dementia through musculoskeletal motion analysis algorithm and virtual reality content. Through motion recognition algorithm based on motion region design, we will track and analyze the moving radius of the target joint. The purpose of this study is to calculate and evaluate scores based on the time to accomplish the goals on virtual reality contents for the prevention of musculoskeletal disorders and the support of dementia prevention training, and the degree of difficulty, and to analyze the correlation between the results of performing K-MMSE and VR contents.

Epithelioid sarcoma has been well characterized as a distincitve entity. In the classic form, it occurs in the distal extremities of young adults. However, in the proximal form, it was found mostly in the pelvis, perineum, and genital tract of young to middle-aged adults. Morphologically, the tumor cells had promient epithelioid or rhabdoid features with marked cytologic atypia, and grew in a multinodular pattern. Immunohistochemically, cytokeratin, epithelial membrane antigen, and vimentin were positive in the tumor cells. This reports dealt with 32-year-old male lesion on his perineum. The tumor shows typical features of proximal type epithelioid sarcoma. We also discussed pathological differential diagnosis and prognosis on this particular disease.

Most patients with temporomandibular disorder can be treated conservatively. However, open TMJ surgery can be needed in some patients. We analysed the patients with TMD which open surgery has performed since 1998. Open surgery was carried out in 8 patients. Age ranged from 22 to 61 years, with a mean of 42.8years. All patients were male. Final diagnosis was obtained based upon clinical, radiographic and operative finding as follows; habitual luxation, bony ankylosis, traumatic arthritis, disc displacement with destructive change, disc displacement and adhesion. Etiologic factors included trauma(4), infection(2), and unknown(2). Open surgery included arthroplasty with either of condylectomy, eminectomy, meniscoplasty, capsurrohaphy. All patients were recovered uneventfully without severe complications. Some mouth opening limitation and mouth opening deviation remained. Postoperative aggressive physical therapy and careful follow up were performed. In conclusion, open TMJ surgery must be considered in organic disease such as ankylosis, tumor and TMD without favorable recovery after long-term conservative therapy.

Objectives Migratory pathogenic factor(六淫) occupies an important position in the etiology of Korean Medicine. This paper shows how Dampness, one of Migratory pathogenic factor(六淫), is explained in Donguibogam(東醫寶鑑). And, based on this, we will figure out how to make a judgement of Dampness through diagnosis. Method 1. Collect parts of Dampness mentioned in Donguibogam(東醫寶鑑). 2. From the collection, extract contents about mechanism and symptom of Dampness, which is considered necessary for diagnosis. 3. Put all the extraction together, suggest the diagnosis element which can be criteria of judgement of Dampness through diagnosis. Result & Conclusions The occurrence of Dampness come from a wet climate and environment externally, and overeating of greasy food and digestive disorder internally. There are many different kinds of symptoms throughout the body cause of poor circulation. Dampness is classed as Cold-dampness, Damp-heat, and Dampness-phlegm depending on characteristic symptoms, and mainly shows musculoskeletal disease and digestive troubles. Typical symptoms are pitting edema, distention and fullness, moderate and thready pulse, volume of perspiration increase, loose feces, urine volume decrease, pain of joint and muscle, restriction of movement, etc.
