PURPOSE: Preservation of adequate vascular access is of vital importance for patients undergoing chronic dialysis in renal failure. The aim of this study is to evaluate the successful access rate and risk factors of arteriovenous fistula (AVF) in the arm for dialysis at a single center. MATERIALS AND METHODS: Patients undergoing vascular access operation between January 2006 and December 2011 were retrospectively identified. RESULTS: A total of 362 vascular access operations were performed. There were 338 autologous AVFs (93.4%) and 24 prosthetic grafts (6.6%). Men comprised 58.3% of all subjects. Mean age was 59.5+/-14.7 years. There were 187 diabetes mellitus patients (51.7%). There was a mean duration of 70.3+/-21.1 days between access creation to first cannulation. Overall successful access rate for dialysis was 95.9%. Of 338 autologous AVFs, 326 patients had patent AVFs for dialysis (96.4% surgical success rate), while 21 of 24 prosthetic grafts were patent (87.5% surgical success rate). A total of 141 patients (38.9%) came to surgery with preoperative central venous catheters (CVC) of which 130 (35.9%) AVFs had a patent fistula in the arm. The only risk factor related to successful access rate of AVF was preoperative CVC placement (P=0.012). CONCLUSION: Successful vascular access rate was 95.9%. The only risk factor related to patent access of AVF was preoperative CVC placement. At least 6 months prior to expected dialysis, AVF surgery is recommended, which may overcome the challenge of co-morbid conditions from having a preoperative CVC.

A 7 day old female baby suffered from perinatal asphyxia and trauma at birth. Subsequently, she had a violeceous subcutaneous plaque on back. The clinical setting, the skin manifestation and the histologic findings of the lesion were diagnostic of subcutaneous fat necrosis of the newborn. Histologic findings revealed fat necrosis with infiltration of inflammatory cells, foreign body giant cells and several fat cells contain needle shaped cleft in radial arrangement. Four weeks latter, the skin lesion was healed spontaneously.

A female newborn had the following characteristics; a congenital localized absence of skin over the lower extremities; blistering of the skin or mucous membrane, incited by trauma, which heals without scarring; and congenital absence or deformity of the nails. In respect to the characteristic manifestation, clinical course and electron microscopic features, our patient seems to fit well into Bart's syndrome. The inheritance pattern appears to be autosomal dominant but, as in this report, isolated cases have been recognized. As the review of the literatures, congenital localized absence of skin has been observed in various subsets of inherited E.B. But, we believe that the term Bart's syndrome should be used to identify patients with good prognosis as the Bart's initial description To the best of our knowedge, this is the first reported case of Bart's syndrome in the korean literature.

A 30-year old female had proximal muscle weakness, periungal telangiectasia and purplish red erythema and edema on the face. Diagnosis of dermatomyositis was estabiiished by clinical manifestations, muscle enzyme study, electromyogram, histologic findings of skin and muscle. She was treated with systemic steroid with some improvemellt. About 1 year after the onset of dermatomyositis, aggravated skin lesion and exophthalmos were noted on right eyelid. Orbit computerized tomography scan showed maxillary carcinoma. She treated with systemic steroid, 5-fluorouracil and cis-platin with partial remission and some improvement of dermatomyositis.

Avascular necrosis of the carpal lunate (Kienbock's Disease) was first described by Peste in 1843. It's etiology is still unknown. Since Lippman, in 1949, there have been many operative treatments for this disease but they had many complications and technical difficulties. The treatment of Kienbock's disease by resection of the lunate and replacement with fascia lata through the dorsal approach is very simple in operation method and its results were satisfactory in follow up study for postop 12, 18 months. We report two cases of Kienbock's disease with brief review of literature.

7.Understanding Atelocollagen Injections for Patients with Foot and Ankle Diseases

Collagen is the most common structural protein in the connective tissues of vertebrates, playing a crucial role in maintaining the tissue structure and wound healing. Atelocollagen retains the original properties of collagen but does not induce inflammatory cytokines. Atelocollagen is extracted from various animals and humans, with bovine-derived collagen being the most commonly used. The safety and efficacy of atelocollagen have been demonstrated through multiple studies, but further research will be needed in the field of orthopedics regarding its range of use and effects. Foot and ankle diseases have attracted little research attention, highlighting the need for further studies.

Purpose:
There are no effective treatment methods with which to control complications of radiation proctitis with fistula or recurrent bleeding following radiation treatment for prostate, cervical, or rectal cancer. Mesenchymal stem cells (MSCs) can induce immune modification, resulting in tissue repair and regeneration. Therefore, we used a rat model of radiation-induced proctitis and observed the effects of using human placenta-derived (PD) and adipose tissue-derived (AD) MSCs.
Materials and Methods:
Female Sprague Dawley rats were irradiated at the pelvic area with 25 Gy. We injected 1×10 6 cells of human PD-MSCs, human AD-MSCs, human foreskin fibroblasts, and control media into the rectal submucosa following irradiation. We sacrificed rats for pathologic evaluation.
Results:
Fibrosis on the rectum was reduced in both MSC groups, compared to the control group. Mucosal Ki-67 indices of both MSC injected groups were higher than those in the control group. Although caspase-3 positive cells in the mucosa gradually increased and decreased in the control group, those in both MSC injected groups increased rapidly and decreased thereafter.
Conclusion
We demonstrated the effects of regional MSC injection treatment for radiation-induced proctitis in rats. MSC injection reduced fibrosis and increased proliferation in rat mucosa. Human AD-MSCs and PD-MSCs had similar effectiveness.

Colloid cyst is a congenital lesion which is thought to be derived from the primitive neuroepithelium, and is most frequently located in the anterior half of the third ventricle. Colloid cysts rarely occur in the pituitary gland, and we describe a case of pituitary colloid cyst, including the CT, MRI and pathologic findings.

A study was to evaluate the efficacy and clinical utility of second look operation in the managements of malignant ovarian tumor at the Department of Obstetrics and Gynecology, Kosin medical colleage from January 1986 to September 1993. Of 220 patients diagnosed as ovarian cancer, 48 patients who had underwent primariy laparotomy were performed second look operation. Thirty-seven patients were found to have no evidence of disease. The result revealed that negative second look operation rate was noted 96.3% at stage I, 66.6% at stage II, 50.0% at stage III, and 42.9% at stage IV and total negative second look operation rate was 77.1%. The 2 year survival rate for stage I, II, III, IV were 85.2%, 66.6%, 50.0% and 42.9% respectively. The survival rate of negative second look operation was 86.5%, that of positive second look operation was 18.1%. In conclusion, second look operation in early stage ovarian cancer need to be justified.
