We reviewed 40 cases of femoral shaft fractures in children treated with split Russel traction and initial fracture angulation above 10 degree. The treatment of femoral shaft fractures in children is various according to age. Satisfactory results have been reported with split-Russel traction. At an average follow-up of 33 months, we obtained following results about remodelling of fracture site & physeal site, possible acceptable angulation of fracture. 1. The average time of traction was 18 days, and hip spica cast was applied for 28 days. 2. Malunion within 25degrees in flexion & 23degrees in valgus & 24degrees in varus was well corrected spontaneously. 3. Average correction of initial angular deformity was 86% at last follow up. 4. Anterior angulation was corrected at 83%, varus 87%, valgus 88%. 5. Remodelling according to direction of deformity was no statistical correlation (P>0.05), and then spontaneous correction of angular deformity was same without relation to direction of deformity. 6. Remodelling according to site was statistical correlation (P<0.05), fracture site 26%, physes 74%. And proximal physes 36%, distal physes 38%.

There is a wide array of designation for cutaneous vascular disorders based on clinical characteristics, histology, embryology, cellular biology, and hemodynamics. The cutaneous vascular disorders can be divided into hemangioma and vascular malformation according to the biologic classification based on cell kinetics i.e. endothelial hyperplasia. There are clinical and histologic differences between them. In this study, clinical, histologic and im-munohistochemical evaluations were attempted on 40 cases of cutaneous vascular disorders diagnosed the period between 1985 and 1993. The results are as follows: 1) Twenty-three out of forty cases were immunoreacive for proliferating cell nuclear antigen(PCNA). The lesions composed of capillary-sized blood vessels with endothelial hyperplasia were diffusely reactive, whereas those composed largely of dilated blood vessels with or without focal endothelial hyperplasia were only focally reactive. 2) Each groups of the classic classification contained both reactive and nonreactive cases except nevus flammeus and juvenfle hemangioma. 3) In contrast to the cases nonreactive for PCNA, those reactive for PCNA contained areas of proliferating small vessels, which showed reactivity for PCNA. In conclusion, the cutaneous vascular disorders diagnosed by the classic classification are heterogeneous in the pattern of the endothelial hyperplasia and the PCNA staining. Therefore it should be classified by the clinical and the histologic characteristics.

Aneurysmal bone cyst uncommonly involves the pubic bone and tends to grow eccentrically and thin out overlying cortex. In the following case report, a 19-year-old male patient visited out hospital, because of dull pain in his left groin. He was diagnosed as aneurysmal bone cyst originated from the superior pubic ramus by CT guided needle biopsy. Transcatheter arterial embolization was effective in the treatment of this lesion such as complete consolidation after the procedure. At present, 2 years follow-up, no problem was noted at weight bearing as well as hip function or recurrence.

OBJECTIVE: This is a retrospective review of 22 surgically treated benign and malignant tumors of brachial plexus region to describe clinical presentation, the characteristics of brachial plexus tumor and clinical outcomes with a literature review. METHODS: Twenty-one patients with consecutive 22 surgeries for primary brachial plexus tumors were enrolled between February 2002 and November 2011 were included in this study. The medical records of all patients were reviewed. RESULTS: Eleven male and 10 female patients were enrolled. Mean age was 39 years. Three patients had brachial plexus tumor associated with neurofibromatosis (13.6%). Presenting signs and symptoms included parenthesis and numbness (54.5%), radiating pain (22.7%), direct tenderness and pain (27.2%), palpable mass (77.3%). Twelve patients presented preoperative sensory deficit (54.5%) and 9 patients presented preoperative motor deficit (40.9%). Twenty tumors (90.9%) were benign and 2 tumors (9.1%) were malignant. Benign tumors included 15 schwannomas (68.2%), 4 neurofibromas (18.2%) and 1 granular cell tumor (4.5%). There were 1 malignant peripheral nerve sheath tumor (MPNST) and 1 malignant granular cell tumor. Gross total resection was achieved in 16 patients (72.7%), including all schwannomas, 1 neurofibroma. Subtotal resection was performed in 6 tumors (27.3%), including 3 neurofibromatosis associated with brachial plexus neurofibromas, 1 MPNST and 2 granular cell tumor in one patient. CONCLUSION: Resection of tumor is the choice of tumor in the most of benign and malignant brachial plexus tumors. Postoperative outcomes are related to grade of resection at surgery and pathological features of tumor.

Treatment of Rupture of Achilles tendon was first reported by Pare, 1575 and thereafter the various causes, diagnostic & therapeutic method of the ruptured tendon have been described by many authors. The two options of treatment are conservative management and surgical treatment and currently surgical intervention has been more popular. There are various surgical techniques which have been reported by many surgeons to treat the acute rupture of the Achilles tendon. In this report, 18 cases ( 11 male & 7 female ) of injuried Achilles tendon had been treated by the modified Lindholm method and follow-up study of 18 cases had been made during 28 months from august. 1993 to december, 1995. The results as follows; 1. After repair by the modified Lindholm method, a long leg cast was applied, and then aweight bearing was started average 8 weeks postoperatively. It can be demonstrated to shorten hospitalization and early ambulation compared to other surgical techniques 2. Postoperative power of triceps surae muscle was improved to normal in 15 patients ofthe 18 patients, and muscle power was good in 3 patients, but, all cases was improved to nearly normal whithin the last follow up. 3. Heel to floor distance was 0.6cm less on the operated side than on the normal side, and the difference decreased to 0.2cm at the last follow up. 4. The calf atrophy was minimal, and active range of motion of ankle was within normal limit. 5. We suggest that the procedure is recommended for one of the methods of the treatment of acute rupture of the Achilles tendon, because it is easy to do and permits early weight bearing and the complication is less.

It is important to follow strict indications for surgery and recognize prognostic factors in order to get good results in the surgical treatment of herniated nucleus pulposus. 55 patients with herniated nucleus pulposus were studied who had had laminectomy and discectomy and were followed up for more than 1 year in order to analyze the correlation between various factors including history, physical examination and radiologic finding and surgical results. Age, sex, symptom duration, location of the herniation, smoking, occupation, physical examination, disc height change, MRI findings, operation time and bleeding volume were evaluated as prognostic factors that seemed to influence surgical result. The results are as follow 1. Female had significantly better surgical results than male (P<0.05). 2. Non-smokers had significantly better surgical result than smokers (P<0.01). 3. In MRI finding, protruded disc had significantly better surgical result when it had involved spinal canal posterolaterally than centrally (P<0.01). 4. The less bleeding volume, the better surgical result (P<0.05).

The human papillomavirus (HPV)-18 E7 (E7) oncoprotein is a major transforming protein that is thought to be involved in the development of cervical cancer. It is well-known that E7 stimulates tumour development by inactivating pRb. However, this alone cannot explain the various characteristics acquired by HPV infection. Therefore, we examined other molecules that could help explain the acquired cancer properties during E7-induced cancer development. Using the yeast two-hybrid (Y2H) method, we found that the Elk-1 factor, which is crucial for cell proliferation, invasion, cell survival, anti-apoptotic activity, and cancer development, binds to the E7. By determining which part of E7 binds to which domain of Elk-1 using the Y2H method, it was found that CR2 and CR3 of the E7 and parts 1–206, including the ETS-DNA domain of Elk-1, interact with each other. As a result of their interaction, the transcriptional activity of Elk-1 was increased, thereby increasing the expression of target genes EGR-1, c-fos, and E2F. Additionally, the colony forming assay revealed that overexpression of Elk-1 and E7 promotes C33A cell proliferation. We expect that the discovery of a novel E7 function as an Elk-1 activator could help explain whether the E7 has novel oncogenic activities in addition to p53 inactivation. We also expect that it will offer new methods for developing improved strategies for cervical cancer treatment.

The seat belt is designed for safety in a motor vehicle and should be worn to prevent severe injuries. But, the seat belt itself can be an injury factor in combination with deceleration forces applied to fixation points of mobile viscera. Here, we present a 23-year-man with traumatic transection of the appendix, highly mobile viscera, following seat belt injury.

Churg-Strauss syndrome (CSS) is a systemic necrotizing vasculitis of the small and medium vessels, associated with extravascular eosinophilic granulomas, peripheral eosinophilia, and asthma. The exact etiology of CSS is unknown. This syndrome commonly affects the lungs, peripheral nerves, skin, heart, and gastrointestinal tract, but rarely the central nervous system. Subarachnoid and intracerebral hemorrhage in CSS patients is extremely rare; however, clinicians should consider that CSS may be a cause of intracranial hemorrhage and its high rate of mortality and morbidity. The authors report on two cases of subarachnoid and intracerebral hemorrhage with CSS and discuss a brief review of CSS.

OBJECTIVES: Idiopathic REM sleep behavior disorder (RBD) is by far the strongest clinical predictor of neurodegenerative disease available. Several potential early diagnostic markers of neurodegenerative disease including autonomic symptoms have been proposed, but they have generally not been tested in presymptomatic neurodegenerative disease. So the authors investigated autonomic symptoms and their associated factors in idiopathic RBD patients. METHODS: 52 idiopathic RBD patients and 52 controls participated in the study. Autonomic symptoms were evaluated by applying the unified multiple system atrophy rating scale (UMSARS) and measuring orthostatic systolic blood pressure drop. RESULTS: Idiopathic RBD patients showed significantly higher UMSARS subscale scores and sharper drop of orthostatic systolic blood pressure than controls. In multiple linear regression analysis, all autonomic symptoms and measured orthostatic systolic blood pressure drop were associated with RBD. In addition, orthostatic symptoms were associated with medication and age, urinary function was associated with benign prostatic hyperplasia, and measured orthostatic systolic blood pressure drop was associated with hypertension. CONCLUSION: In this study, idiopathic RBD patients showed more autonomic symptoms than controls. However, other autonomic symptoms-related factors also influenced some autonomic symptoms. Prospective studies should be performed to evaluate autonomic symptoms as a potential predictor of neurodegenerative diseases.
