A new balloon dissector, a modification of a Foley catheter, was devised and it can be used either as a dissector or a tissue expander. Since most operating time was spent in balloon manipulation (inflation/deflation), the duct for saline injection was made to be wider than the Foley catheter. As a result, the balloon could be inflated faster than before. In order to reduce the scar at the donor site, harvest of the sural nerve using endoscopic technique is currently applied, but utilization of this method is technically difficult and requires a long operating time. For these reasons, new our method of using a balloon dissector was devised. The balloon dissector can also be used for immediate intraoperative tissue expansion for the reconstruction of small skin defects without distortion. We have found that the advantages of using the new balloon dissector include a reduction in operating time, preservation of the perforating vessels, and primary closure with less tension. In addition, this simple and inexpensive instrument is cost-beneficial to patients.

BACKGROUND: PTCA is often unsuccessful in a patient with chronic total occlusion of coronary arteries with success rates varying from 60 to 70%. Success rates are related to the duration of total occlusion, longer occlusions being associated with lower success rates. Chronic total occlusion may be associated with thrombi superimposed on the stenotic lesion. We used an intra-coronary bolus of urokinase followed by a prolonged urokinase infusion in an attempt to lyse the lesion and allow for passage of the PTCA wire during subsequent angioplasty. The purpose of prolonged durokinase infusion was to reduce the clot sufficiently to recanalize the coronary artery and make it more amenable to PTCA. METHODS: Study patients: We were included six patients who developed total occlusion for more than 3 weeks and good collateral channels of Grade 2 or more and previous attempts at angioplaty had failed. Procedures: All patients underwent dual catheter system and incremental dose protocol of intracoronary urokinase infusion. RESULTS: The mean duration of occlusion was calculated to be 65.3+/-2.7 weeks and urokinase dose ranged from 130,000 to 200,000U/hr and treatment lasted 21.7+/-1.4 hours in our study. The prolonged urokinase infusion resulted in reperfusion of the occluded dvessel in 5 of the 6 patients(83%), with or without the complementary balloon inflation. One patient failed to recanalize the occluded vessel because cardiac tamponade was developed during the prolonged urokinase infusion. CONCLUSION: We concluded that the prolonged urokinase infusion in occluded coronary artery appeared to increase the likelihood of successful PTCA in patients with chronic total occlusion of coronary arteries.Also, in carefully selected patients, prolonged urokinase infusion in occluded coronary artery was relatively safe and well tolerated.

OBJECTIVES: The aims of this study were to know the prevalence of cognitive disorders in patients with thyroid cancer, and identify related variables to them. METHODS: Subjects were consisted of fourty-two patients with thyroid cancer, who were admitted for radioiodine ablative therapy at 6-12 months after total thyroidectomy. The data were obtained from interviews about history and assessments of depression and cognitive function(Korean Version of the Montreal Cognitive Assessment, MoCA-K). RESULTS: 1) Among subjects, those with below 22 of total score of the MoCA-K were twenty-one(50.0%). 2) Upon age, education, Pre-radioiodine therapy thyroid stimulating hormone(TSH), there were statistically significant difference between subgroup with above 23 of the total MoCA-K score and those below 22. 3) The total scores of the MoCA-K in subjects had significant correlation with age, education, comorbidity, Pre-radioiodine therapy TSH, total score of the HDRS-17. CONCLUSIONS: Cognitive disorders were more prevalent among patients with thyroid cancer before radioiodine therapy. Therefore, further study should be needed to clarify the mechanism for the cognitive disorders in thyroid cancer. Furthermore, physicians should pay attention to the cognitive function and prepare preventative measures for cognitive disorder during management of thyroid cancer.

The lymphangioma is a benign vascular tumor and, like hemangioma, represents a hamartomatous growths. The site of predilection include the head, neck. and axillae. Lymphangiomas tend to involve the bulbar conjunctiva as well as the eyelid and orbit. Histopathologieally three types of lymphangioma are encountered: demal, cavernous and cystit types. The clinical signs are proptosis, diffuse hematoma of eyelid and subconjunctival hemorrhage. Asymptomatic cases can be observed. The authors experienced a case of multiple lymphangiomas on the right supraorbital area in a 14-year-old man and reported light microscopic and electron microscopic findings of the lymphangioma.

PURPOSE: The aim of this study is to evaluate the general status and prevalence of cerebral palsy, the complication and the activity of daily living in patients with cerebral palsy in Holt Ilsan Home. METHODS: Cross-sectional study was performed on 113 cerebral palsy patients in Holt Ilsan Home with the medical records review, the physical examination, and the Modified Barthel index for the independency of activities of daily living. RESULTS: The mean age of subjects was 28.1+/-12.7 years and the duration of residence was 22.9+/-12.8 years. The most common type of cerebral palsy according to the muscle tone abnormality was spastic type(53.1%). The most frequent condition in which extremities are involved were quadriplegia in 46.0%. The score of Modified Barthel index was significantly lower in mixed type for 16.9+/-24.0 and quadriplegic type for 14.8+/-25.5 compared with others. CONCLUSION: This study indicates that cerebral palsy patients in rehabilitation facility have severe medical problems such as musculoskeletal complications, visual and language problems, epilepsy and dependency in activities of daily living. Therefore more medical attention like long-term follow-up study and social supports is needed.
