Objective: The cut-off value for hypercholesterolemia and normal HDL levels for Korean children are still not established despite increasing hypercholesterolemia with recent socioeconomic change. One of the aims of this study is to screen the serum total cholesterol and HDL levels in normal Korean shool children, and another is to evaluate the relationships between serum lipid levels and obesity. Methods: Venous blood samples for cholesterol and HDL were taken in the morning after overnight fasting from 152 healthy school children who live in Seoul. Body weight and height were measured and obesity indices were calculated also. Results: Of the healthy 152 school children, mean level of serum total cholesterol was 185.7mg/dL and that of HDL was 52.8mg/dL. Boys had higher total cholesterol levels than girls (190.5mg/dL vs. 180.0mg/dL). Sexual difference of HDL was not found and the mean proportion of HDL to total cholesterol was 28.9%. There was moderate reverse correlation between total cholesterol and proportion of H to total cholesterol. There were no correlations between total cholesterol, HDL and obesity index each other. To our surprise, children with high serum total cholesterol levels were not always obese and vice versa. Moreover, children with high total cholesterol tended to have relatively low HDL proportion to the total cholesterol, which meant high risk of astheroselerotic change in thefeature. Conclusion: In normal chidren, serum total cholesterol level is not correlate well with obesity in most cases. Current thought of the pediatrician that serum total cholesterol will be checked in obese child only may many normal looking hypercholesterolemias. More wide studies must be necessary to get the normal values of serum lipid and to make an appropriate screening system for hypercholesterolemia in Korean children.

Once ischemic necrosis occurs in the tissue below an injury site after trauma, a vascular injury is suspected first. On the other hand, it is not common for a blood vessel to become obstructed after a delay of a few days after the initial trauma. The authors experienced a case where the blood flow was maintained at the time of a femoral fracture injury and immediately after surgery, but the femoral artery was occluded later. On the 5th day after surgery, ischemic necrosis of the lower limb was confirmed and treated. This case is reported with a review of the relevant literature.

PURPOSE: To evaluate the results between open reduction and internal fixation with the plate and percutaneous reduction by towel clip and intramedullary fixation with Steinmann pin for clavicle shaft fractures in adult. MATERIALS AND METHODS: We have studied the results in 33 cases with the plate, 35 cases with the Steinmann pin among total 68 cases of clavicle shaft fracture. The patients were followed up over a period of at least 12 months. The final postoperative outcome was analyzed with the clinical outcomes using Kang's criteria, radiological union time and operation time. RESULTS: The clinical outcome that was good or excellent according to the Kang's criteria showed a distribution of 88% in the group using the plate with 29 cases out of total 33 cases, 91% in the group using the Steinmann pin with 32 cases out of total 35 cases. The mean radiological union time was 8.9 weeks in the group using the plate, 9.1 weeks in the group using Steinmann pin. The mean operation time was 72 minutes in the group using the plate, whereas was 18 minutes in the group using Steinmann pin. CONCLUSION: In the treatment of adult clavicle shaft fracture, two groups did not show a significant statistical difference in clinical and radiological outcomes. However, the operation time and postoperative functional recovery was significantly shorter and faster in the group using Steinmann pin. Additionally economic and cosmetic aspect was more satisfactory in the group using Steinmann pin.

We analyzed 20 cases of traumatic carotid cavernous fistula(CCF) during the recent 10 years The results are summarized as follows: 1) In 18 cases(90%), the clinical symptoms & signs of CCF occurred within 2 months after trauma. 2) The sites of fistulae were common in horizontal segment(40%) and at the junction(30%) between horizontal segment and posterior ascending segment of cavernous portion of internal carotid artery. 3) The main draining veins of CCF were the superior ophthalmic vein(90%) and the inferior petrosal sinus(70%). 4) The methods of treatment were occlusion of fistula with balloon(9 cases), occlusion of cavernous ICA with balloon(2 cases), ligation of cervical ICA with Poppen's clamp(4 cases) and trapping(2 cases). Two patients were not treated and another patient was healed spontaneously. 5) The frequency and severity of complication was significantly decreased in cases treated by detachable balloon occlusion than by direct cervical ICA ligation or trapping procedures. 6) The procedure using the self-sealed goldvalve balloon was simple, but had a risk of premature separation and premature deflation.

Hemangiopericytomas is a rare malignant tumor of the central nervous system having an incidence of 1-3.8% of all primary intracranial meningeal tumors, and the occurrence of cystic hemangiopericytomas is even rarer. We report our recent experience of a case of cerebral hemangiopericytoma associated with a large cyst in a 38 year-old man. The patient presented with 1-month history of headache. Computerized tomography(CT) and magnetic resonance image(MRI) showed a huge-sized, cystic tumor in the left frontal region. Histopathological report of the excised tumor confirmed cystic hemangiopericytoma. Over the years, the issue of classifying hemangiopericytoma as a form of meningioma has been controversial. Since hemangiopericytoma differs from that of ordinary meningiomas because of its extremely malignant behavior and different histological and ultrastructural properties, the author suggest that hemangiopericytoma classified not with meningiomas. Regardless of classification, total surgical removal of this tumor is crucial due to its tendency for local recurrence despite aggressive resection.

The familial occurrence of meningiomas without evidence of neurofibramatosis was very rare. Recently, we experienced a family in which a mother and a daughter had histologically similar tumors. There was no evidence of von Recklinghausen's neurofibromatosis in either of the subjects or in other members of their family who were examined. The evidence to support heritability of meningiomas in the general population remains inconclusive, by gentic factors contribute to the etiology of meningiomas in isolated families.

The authors reported the cases of 23 patients with aneurysms measuring 2.5 cm or greater in diameter found during 7 years period in which we performed 596 operations for aneurysm of the 23 patients, 14 were treated by direct operation, 3 by internal carotid ligation with or without bypass surgery, 2 by trapping, 1 by wrapping and the other 3 by conservative therapy. The overall incidence of giant aneurysms was 3.9% but varied according to location; 9 cases were located on the internal carotid artery; 8 were on the anterior communicating artery; 5 were on the middle cerebral artery. 14 patients had hemorrhagic attacks, 7 had mass effects from the aneurysm, and 2 had ischemic events. Overall favorable outcome was 65% and the mortality was 13%. Based on the review of the literature, the appropriateness of surgery and surgical methods are discussed.

Direct operation for ruptured aneurysm should be the choice of treatment in elderly patients same as in younger cases. The early operation is an effective and reliable method to reduce the occurrence of rebleeding, vasospasm, ischemic complication, medical complication & to shorten lengths of hospitalization. To evaluate the risk of early operation of elderly patients with ruptured cerebral aneurysm. conducted a retrospective analysis 81 elderly patients with ruptured aneurysms who were over aged 60 years between Jan 1985 to June 1988. Of these, 47 case were performed early operation in which the direct intracranial operation was carried out within 3 days after last subarachnoid hemorrage. 77 % had favorable outcome and 13% died.

The incidence of intracranal aneurysm is rare in childhood and adolescence. During the period from January 1982 through December 1989, 793 aneurysms were operated on the our department. Of these 8 aneurysms occurred 8 patients under age of 18 years. The average age was 11.6 years(range 4 to 18 years). There were 6 male and 2 females. Presenting sings and symptoms included SAH in 6 aneurysms and focal neurologic deficits in 2 aneurysms. All aneurysms were surgically treated : direct clipping was performed in 6, aneurysmorraphy in 1, trapping alone in 1. The postoperative result were excellent in 5, good in 2, and fair in 1. The rarity of such lesions in childhood and adolescence and their pathogenesis are reviewed briefly.
