In normal hurnan dermis, factor XIIIa positive dermal dendrocyte are located in the papillary areas closely associated with blood vessels and the upper reticular dem These cells represent a specific type of bone marrow derived dermal cells, distinct from Langerhans cells having some features in common with rnonocyte/macrophage lineage and with potential antier presenting activity. Although the significance of these cells has not yet been fully established, it been suggested that they play a major role in skin immune iesponses, in collagen synsthesis regultic and in wound repair. We report a case of acaqired fibrokeratoma which is studiec conventional histopathology and immunohistochemistry. Histopathologic findings of this case showed ovascular proliferation and the increased presence of fibroblast like cells as a common fe;ture of these benign tumors. Immunohistochemical staining with anti factor XIIIa antibody deiaoi strates increased numbera of positive dendritic cells in the upper dermis. There finding supports the fat that some fibroblagt like cells in the upper dermis of acquireid fibrokeratoma may be factor XIIIa positive dermal dendritic cells.

There has not been any report on massive air-containing liver abscess in diabetic patients, although emphysematous cholecystitis or pyelonephritis is a well-known complication in them. Authors report two cases of emphysematous liver abscess in diabetic patient, which showed typical findings of massive air-containing hepatic abscess on ultrasonography and computed tomography, but very poor progrosis in spite of immediate and successful percutanoeus drainage procedure.

The incidence of pancreatic trauma is increasing and still remains a major source of morbidity and mortality. We have graded the pancreatic trauma on CT according to its pattern into four grades. We also determine the accuracy of CT in the evaluation of pancreatic trauma and the role of CT for delineation of pancretic ductal injury which is critical factor in outcome of pancreatic trauma. CT correctly diagnosed the pancreatic trauma and its traumatic pattern and severity in 22 of 25 cases. Pancreatic enlargement was the most common findings observed in 19 cases. Other findings were 15 cases of intrapancreatic low density hematoma, 12 cases of parenchymal fracture which were predilected in pancreatic neck area. CT grade III and IV could predict the pancreatic ductal injury, and was well correlated with severity of posttraumatic pancreatitis, duration of admission days and incidence of complications. So we concluded that CT can play a definite role for diagnosing and determining the prognosis of pancreatic trauma.

Forty five patients with inferior vena cava (IVC) thrombosis were studied with the use of ultrasonography (US) and computed tomography (CT). Thirty seven cases were cased by tumor extension and the primary neoplasms were hepatocellular Ca. (26cases), renal cell Ca. (6 cases), Wilms' tumor (1 case), IVC leiomyosarcoma (1 case) and retroperitoneal metastatic tumor (3 cases). Non-tumor thrombus were 8 cases which included 5 cases of Budd-Chiari syndrome and 3 cases of thrombophlebitis. US and CT both were good for the diagnosis of IVC thrombosis. Cranial extension was better demonstrated by US whereas CT yielded better delineation of the lower extension. Even though, differentiation of tumor non-tumor thrombi by the echogenecity and density of the thrombus was not possible, the finkdings of adjacent tumor mass, complete obstructive thrombus within dilated lumen with bulging wall, and nontapered acute margin of thrombus made the possibility of tumor thrombus more likely.

Correction of alveolar cleft with bone grafting has become a well-established step in the integral management of cleft lip and palate patients. Secondary bone graft at mixed dentition is a widely accepted protocol and iliac bone graft is recommended as the gold standard by a multitude of cleft centers. However, grave morbidities of the iliac donor site have discouraged cleft surgeons from adopting this reliable method. In this study, percutaneous bone biopsy set was used to avoid the morbidities of conventional iliac bone graft. Iliac bone graft was performed on 20 patients with alveolar cleft during the period from January 1995 to February 1999. The tube saw of the bone biopsy set was introduced through a small incision of less than 1 cm, and cancellous bone cores were harvested from the iliac crest. After the pericoronal incision, a wide gingival mucoperiosteal flap was elevated at both sides of the cleft. A soft tissue pocket that was created by closure of the nasal and palatal lining was filled with harvested bone cores. Medial transposition and water-tight closure of both gingival mucoperiosteal flaps provided coverage of the bone graft. During the follow-up period from 5 to 50 months (mean, 29 months), completion of the goals of the alveolar bone graft was observed. There was no serious complication except for one case the exposure of the bone graft, and this was resolved spontaneously. Bone harvest with a percutaneous bone biopsy set enables early ambulation by reducing postoperative pain, and it may be faster and simpler than any other method introduced so far. Furthermore, blood loss was minimal, while the scar was small and acceptable. Iliac bone graft with percutaneous bone biopsy is a reliable method for correction of the alveolar cleft and it has many advantages over conventional iliac bone graft and other sources of bone.

BACKGROUND: Despite concern about information of neuropeptide, the has been no baseline study of neuropeptide in Koreans. OBJECTIVE: The purpose of the study was to investigate the skin sinsitivity of substance P and VIP in normal healthy persoas. METHODS: We prepared 1000pM, 100pM, 10pM solution of substan P 1-11, substnace P 1-7, substnace P 7-11, and VIP. We injected intradermally 50ul of the br ve solutions on 12 sites of both forearms in addition plaebo. We measured the size of the area of flare and wheal along time. We repeated the same test after antihistamine intake. RESULTS: Flare and wheal respinses were dose dependent. Injection of substance P 1-7 did not evoke wheal responses and injection of substance P 7-11 did not wake flare responses. Flare responses of substance P 1-11, ubstance P 7-11, VIP were inhibiteb antihistamine and wheal responses of VIP were inhibitedly antihistamine. CONCLUSION: N-terminal of subtance P is responsible for flarers onses and C-terminal of substnace P is responsible for wieal responses. Flare responses of sisance P were mediated by histamine but wheal responses osubstance P were direct effect on postcapillary venule. Flare and wheal responses of VIF were mediated by histamine.

Revascularizations of 14 occlusive arterial diseases in the lower extremities with the Transluminal Endarterectomy Catheter was done successfully. The causes of occlusions were atherosclerosis in 9 cases and cardiogenic thromboembolism in 5 cases. The site of lesions were at the common femoral artery in 1 case, the superficial femoral artery in 6 cases and the popliteal artery in 7 cases. The length of the lesion were below 5cm(n=3), 5-10cm(n=2), 11-20cm(n=6) and 21-30cm(n=3). Complications were distal embolism(n=1) and hematoma at the puncture site(n=1). No symptoms recurred in any cases during 2 months -15 months followup. Endarterectomy with Transluminal Endarterectomy Catheter was found to be an effective method for revasculizations of occlusive arterial disease in the lower extremity, especially in long segmental occlusion.

Korean Journal of Dermatology 1981;19(3):359-363
Nevus lipomatosus cutaneous superficialis is a very rare skin disease which usually is present from birth. This uncommon condition is due to collections of ectopic. fat cells within the upper and mid dermis. There are two clinical varieties. The first is a lesion of zonal distribution, present from birth or childhood, usualIy on the buttocks or the lower back. The second form, a dome or sessile, papule, begins. in adult life and is less restricted in distribution. Cerebriform plaques tend to form from the coalescence of soft, yellowish papules. The authors observed two cases of typical nevus lipomatosus cutaneous superficialis. The first case is a 25-year-old female who has had asymptomatic, soft, skin colored, and huge confluent nodules on the right infragluteal fold and upper thigh for 15 years; and the second case is a 15-year-old male who has had multiple, skin colored and soft papules or nodules in zosteriform distribution affecting the right side of the lower back and coccygeal area and right buttock for 4 years. The authors made the diagnosis of nevus lipomatosus cutaneous superficialis from the characteristic clinical and histopathological findings.
