Deep skin and soft tissue defects with exposed bone and tendon is difficult to treat, because skin graft rarely survives and flap surgery is sacrifice of donor site. Since "Stage I" membrane was developed by Yannas and Bruke in 1980, numerous kinds of artificial skin have been developed. The adaptability of "Terudermis", developed by the Terumo Co., as an artificial skin composed of sponge made of a fibrillar atelocollagen and a heat-denatured atelocollagen, was clinically evaluated on application to 13 cases presenting deep skin and soft tissue defect with exposed bones and tendons from October 1997 to march 1998. Terudermis has the advantage of allowing early incorporation of fibroblasts and capillaries into its collagen sponge due to very weak dehydrothermal cross-linking. Before Terudermis graft, several days of wet dressing and debridement were required to prepare healthy well-vascularized bed because Terudermis was weak on unsanitary wounds. After bed preparation, Terudermis was grafted like usual skin graft. Tie-over bolster dressing or compressive dressing was used case by case. The dressing was opened 2~3 days after Terudermis grafting. Wet dressing was done daily until the skin graft was done. Autologous skin graft was done 2-3 weeks after Terudermis graft. Our clinical results indicated that Terudermis was beneficial in treating 77% of our patients. Through the use of this new method, treatment of severe skin and soft tissue defects that are usually treated by musculocutaneous or other conventional skin flaps can be replaced by Terudermis as an new artificial dermis.

Ectopic pancreas is commonly located at stomach, duodenum and jejunum. It is a relatively rare entity and is usually of no clinical importance which especially is a very rare source of massive upper gastrointestinal bleeding. We have recently experienced a case of an ectopic pancreas in the second portion of the duodenum which was proven to be a source of massive gastrointestinal bleeding by duodenoscopy and was confirmed by surgical exploration.

Eleven cases of juvenile diabetes mellitus who were admitted Seoul National University Hospital from Jan., 1969 to Aug., 1978 were aha1yzed. The mean age of onset was 7 and female to male ratio was 8 to 3 with female preponderance. Four had family history of diabetes, although none had diabetic sibling. Polyuria and polydipsia were noted in all cases as initial symptoms, and symptoms of weight loss (6 cases), disturbances in consciousness (5), generalized weakness (5), anorexia (4) and enuresis (3) were noted in the order of frequency. Leucocytosis was noted in 5 cases, but only 2 among the 4 who had infection revealed leucocytosis, The mean blood glucose level was 320 mg% and serum osmolality was 293 mOsm/L. There was no significant difference in the level of blood sugar and serum osmolality according to the consciousness status. Eight episodes of ketoacidosis occured in 5 cases. Three episodes developed due to discontinuance of insulin and three episodes accompanied infection. The mean blood glucose level was 495 mg% and serum osmolality was 300 mOsm/L in ketoacidosis. The consciousness cleared in average 20 hours and ketonuria disappeared in average 26 hours after the administration of insulin (average 5 units/kg of body weight). At discharge, the average dose of insulin needed was 1.2 U/kg/d. Six patients were followed from 6 months to 6 years. Two developed pulmomary tuberculosis during the period of follow up.

PURPOSE: The aim of this study was to examine the relationship between tooth loss and sub-clinical atherosclerosis in Korean adults. MATERIALS AND METHODS: The subjects were part of a cohort study conducted in Ansan city by the Korea University medical school as part of the Korean Genome project. 749 subjects over than 40 years old were evaluated. After taking panoramic radiography, the amount of tooth loss was calculated. The intima-media thickness (IMT) was assessed by using ultrasonography at the common carotid artery. Traditional cardiovascular risk factors for atherosclerosis were also evaluated. The relationship between tooth loss and the IMT was evaluated using ANOVA with Scheffe's multiple comparison method in univariate analysis. Multiple regression analysis was also performed to determine the significance between the IMT and tooth loss. RESULTS: With age, tooth loss increased, but there was no significant increase in other traditional cardiovascular risk factors. Univariate analysis revealed the IMT to be positively related with the amount of tooth loss. Regression analysis of the IMT in the anterior and posterior tooth loss revealed that only the posterior tooth loss was significantly related with the IMT at all sites of the common carotid artery (right far wall, P = .015; left far wall, P = .008; right near wall, P < .001; left near wall, P = .001). CONCLUSION: This study verified the positive relationship between the increased tooth loss at the posterior area and the accumulation of atheroma in arteries.

The term of blow-out fracture refers to a fracture of an orbital wall, typically the orbital floor or medial wall. Especially the medial blow-out fracture is difficulty to approach. Transcutaneous approaches could remain postoperative scars and transconjunctival approaches could give bad visual field and technically difficulties in approaching the medial orbital wall. But the medial transconjunctival incision could avoid an external scar, save the operating time, and decrease injuries of surrounding tissue. Authors operated the medial blow-out fractures through the medial transconjunctival approach and porous high-density polyethylene sheet was placed on fracture site for the prevention of relapse of the orbital contents. 30 cases of medial blow-out fractures were treated using the medial transconjunctival incision. All patients were corrected satisfactorily without leaving any visible scar. Thus the medial transconjunctival approach was an effective way to repair medial blow-out fracture.

Iliac vein compression syndrome is a rare clinical condition in which left common iliac vein is anatomically compressed between right common iliac artery and the fifth lumbar vertebrae or pelvic brim. Patients usually have marked edema of the left leg. Although the actual incidence is unknown, this syndrome most affects women in the second to fourth decade of life. We report 4 cases of iliac compression syndrome treated by surgical intervention during the last fifteen-year period. Among them, two women have suffered from chronic intermittent swelling and pain of left leg, and two men had acute or subacute symptoms. The fibrous web in the entrance of left iliac vein into vena cava existed in one case. Including this one, two were treated by transposition of iliac artery or vein with thrombectomy. One was decompressed the arterial compression by mobilization or adhesiolysis of the surrounding vessles with thrombectomy. To the last one in which the distal common iliac vein was compressed by tortous dilated left internal iliac artery, transsection and ligation of the internal iliac artery was performed. All patients have experienced improved left leg condition after operation. except the last one in which suffered from thrombosis of left popliteal vein after the iliac decompression.
