BACKGROUND: Experience of awareness and recall during general anesthesia would be most distressing for patients. Especially for the cesarean section, medical team must consider both maternal awareness and fetal safety. Authors tried to know the possibility of propofol use as induction and maintenance agent of anesthesia for the cesarean section in respect of maternal awareness, recall and fetal safety. METHODS: Forty patients (ASA physical status 1, 2) were allocated randomly to either propofol (n=20) (P) or thiopental-enflurane (n=20) (T-E) group. We checked B.P, pulse rate, and the incidence of maternal awareness using the isolated forearm technique (IFT). The postoperative interview was conducted between 12~24h after operation. RESULTS: The incidence of maternal awareness signaled by flexing fingers in response to voice commands were significantly lower in the T-E group (20% after induction, no response during other times) than the P group (45% after induction, then 35%, 30%, after 5, 10 min delivery respectively). Seven patients had postoperative recall of introspective awareness in the P group but no patients in the T-E group. The 1 min Apgar score of the newborn were significantly lower in the P group than the T-E group but both groups were within normal range. CONCLUSIONS: Our date indicated that, in comparison with thiopental-enflurane, propofol infusion (6 mg/kg/h) were associated with a greater incidence of awareness during surgery and recall.

Hobnail hemangioma(HH) is a benign acquired vascular tumor of endothelial origin which should be differentiated from other malignant vascular neoplasm such as Kaposi's sarcoma or angiosarcoma. We report a case of hobnail hemangioma in a 21-year-old woman who had a dusky-red patch on her left shin. Histologically, ectatic vascular channels with a single layer of plumped endothelial cells were seen and the vascular channels seemed to dissect the collagen bundles. She underwent treatment with surgical excision with primary closure.

Atypical cutaneous fibrous histiocytoma (ACFH) is not well known and only a small number of cases have been reported. Characteristically, ACFH is found on the trunk and limbs of middle-aged women. Although considerable cellular atypia may be present, it occurs focally, the remainder of the tumor representing more classical cutaneous fibrous histiocytoma. A 37-year-old woman presented with a solitary brownish firm nodule on her right forearm. No other abnormalities were found in her personal or family history. Clinically, the tumor simulated a benign fibrous histiocytoma. Histologic examination revealed a poorly delineated intradermal tumor with the usual appearance of benign cutaneous fibrous histiocytoma, but a variable pro-portion of cells in the tumor were scattered atypical cells or bizarre multinucleated giant cells. We report upon a rare case of ACFH.

BACKGROUND: Canine scabies is caused by an infestation of Sarcoptes scabiei var. canis (S. canis) in dogs and they can be transmitted to humans. Recently pet raising has been increasing in Korea and various parasitic infestations contracted from them have also been increasing including canine scabies. OBJECTIVE: The purpose of this study was to examine the clinical and histopathological features of experimental canine scabies. METHODS: Two dogs experimentally infested were observed for a year. They were examined physically and the numbers of S. cans were counted from scraping samples of the ear, leg and abdomen every 3 to 7 days and skin biopsies were taken. One was given systemic corticosteroids(Dogl) and the other was observed in its natural course(Dog2). RESULTS: Dogl-Clinically severely pruritic, markedly thick hyperkeratotic scales, crust and generalized erythema on the whole body developed with huge numbers(up to 754.9/100mg from scales of the abdomen) of mites, and histopathologically showed features similar to human crusted scabies. Dog2-Clinically showed milder features than Dogl including the number of S. canis(up to 242.6/100mg from scales of the ear), but histopathologically showed similar features with Dogl. Dog2 also showed a prompt response to one topical application of 20% benzyl benzoate solution. CONCLUSIONS: 1) The number of S. canis increased markedly in both normal and corticosteroidtreated dogs, although it was more significantly increased in the corticosteroid-treated one. 2) Histopathology showed features similar to classical scabies in the early stage but features of human crusted scabies in the full-blown stage. 3) Morphologically Sarcoptes canis differs from Sarcoptes scabiei var. hominis.

The ultrasound-guided fine needle aspirations were performed in order to diagnose a suspected neoplastic orinfectious diseases in 52 patients with focal liver disease. Of these, neoplastic lesions were suspected in 31patients and infectious lesions in 21 patients ultrasonically and/or clinically. The overall accuracy for bothsuspected malignant and infectious disease was 79%(41/52). The primary indication for fine needle aspiration wasto document the presense of malignancy and to avoid a diagnostic laparotomy, and to drain hepatic abscesses.Consequently we were convinced that the ultasound

Pellegrini-Stieda's disease is a post-traumatic disorder of the knee. It is characterized by a crescentric-like bony formation in the region of the medial condyle of the femur, which usually makes its appearance upon roentgenographic examination three or more weeks after injury to the knee. During the three and a half years from January 1979 to July 1982, eleven patients were treated by conservative method and only one patient was treated by operation. The results were as follows; l. All give a history of trauma. 2. The major findings in this disease were pain in motion, local tenderness, and limitation of motion. 3. In roentgenographic findings of these cases, we noted the followings: 1) The most common site of the calcification was the proximal area of the tibial collateral ligament. 2) In seven cases (58%), the evidence of calcification was noted in 4 weeks to 12 weeks following original trauma. 3) Eight cases (67%) showed a radiolucent area from 0.5 to 3mm in thickness between the bony shadow and the femur. 4) Eight cases (67%) showed a crescentric shape of calcified area. 5) In seven cases (58%), the size of calcified mass was 1.5 to 3.5cm in length and 1 to 3mm in width. The mean size of calcified mass about 3cm in length and about 2.5mm in width. 4. Eleven cases were treated conservatively and one case was treated operatively. The results were satisfactory, and all patients were able to return to their works.

Diastasis of the ankle joint was associated with extensive ligamentous rupture and resulted from external rotation or abduction injuries at the ankle. It might occur without associated fracture but was more frequently seen in cases of bimalleolar fracture in which there was fracture of the medial malleolus or rupture of the deltoid ligament with fracture of the lower third of the fibula. Thirty patients of diastasis of the ankle joint were admitted and treated by internal fixation with screw and bolt from January 1978 to December 1981. The following results were obtained: 1. The main cause of the injuries was falling from a height and the other causes were slipping down and sports injury in order. 2. The most common type by Lauge-Hansen classification was supination-external rotation type (20 cases, 67%). 3. Partial diastasis of the ankle joint or anterior type was 14 cases (47%) and complete diastasis or total type was 16 cases (53%). 4. In all cases, mixed oblique fibular fracture and medial instability were seen. 5. The good results were achieved in 24 patients (80%).

Juvenile xanthogranuloma is characterized histologically by a dense, sheetlike, well-demarcated, histiocytic infiltration within the papillary and reticular dermis, with occasional extension into subcutaneous tissue, fascia, and peripheral muscle. We report a case of juvenile xanthogranuloma developed in a 5-month-old male infant which showed typical histopathologic features of juvenile xanthogranuloma, involving the papillary dermis only without deep dermal or subcutaneous change.

Halo congenital nevus is a condition in which halo formation is associated with congenital nevocellular nevus. Both humoral and cell-mediated immunity have been implicated to be involved in halo formation. We described a 8-year-old boy with halo congenital nevus characterized by the unique histologic location of inflammatory cells. He has no personal and familial history of vitiligo, dysplastic nevus, melanoma or autoimmune disease. Histologically, the present case of halo congenital nevus undergoing spontaneous regression showed a marked inflammatory infiltrate with remnants of original nevus cell nests in the upper dermis, whereas no inflammatory infiltrate was present in the deep dermis. Most of inflammatory cells were T-cells.
