Our study surveded 418 obese first grade elementary school children(279 male and 139 female), in seoul, and measured levels of serum total cholesterol, HDL cholesterol, LDL cholesterol, triglyceride were measured in addition to the measurement of body weight and height. The following results were obtained. 1) Obesity index was catergorized into mild, moderate, and severe, and the percentage of mild was 6.8%, moderate 48%, severe 45.7% respectively in surveyed children. 2) The average level of total cholesterol was 1.66.60 27.63mg/dl, HDL cholesterol 50.22+/-0.68mg/dl, LDL cholesterol 82.23+/-1.26mg/dl. 3) Atherogenic index was calculated, and obtained value was 2.45+/-0.48. It showed higher statstical significance in boys than in girls(p<0.05). 4) There was no significant difference in average level of total cholesterol, LDL cholesterol, and triglyceride in accordance of the severity of obesity. 5) Statistical significance was found in different average ievels of HDL cholesterol and atherogenic index according to obesity index (p<0.05). 6) There was a statistical significance in the average values of Kaup index and Rohrer index in accordance with obesity index (p<0.000). 7) There was no correlation between abnormal levels of total cholesterol, HDL cholesterol, and LDL cholesterol and the severity of obesity. 8) Abnormal levels of triglyceride, atherogenic index, Rohrer index and Kaup index had a statistical significance since their levels. 9) There was a correlation between atherogenic index and body measurement. Total cholesterol level showed correlation with obesity index, and HDL cholesterol with Kaup index and arm circum ference.

OBJECTIVE: To assess the clinical usefulness of ultrasonography for the diagnosis of mild and very mild carpal tunnel syndrome. METHOD: Ultrasonographic evaluation was performed in 39 hands of 29 patients with mild and very mild carpal tunnel syndrome according to Bland's neurophysiologic grading scale. Controls included 41 hands of 34 subjects without electrophysiologic evidence of carpal tunnel syndrome. Ultrasonographic findings were evaluated quantitatively with regard to the cross-sectional area, the flattening ratio, the swelling ratio of the median nerve, and palmar displacement of the flexor retinaculum. The analysis of differences between controls and patients group were done by independent t-test. Cut-off values using receiver operation characteristic, were calculated. RESULTS: Patients had significantly increased cross sectional area and flattening ratio of the median nerve at proximal carpal area, palmar displacement of the flexor retinaculum at proximal carpal area. A critical value of equal or higher to 8.5 mm(2) for cross-sectional area at the pisiform level showed a sensitivity 79.5%, a specificity of 95.1%, which had most diagnostic value compared with the value of cross-sectional area at the distal radius level, flattening ratio at the pisiform level and palmar displacement. CONCLUSION: Ultrasonography was useful in the diagnosis of mild and very mild carpal tunnel syndrome.

We report a case of intradermal nevus in a 52-year-old female patient, who presented with asymptomatic, solitary papule, which had been on the site for years as a macule on the center of the lower lip, which is a rare site for intradermal nevus. The skin biopsy revealed the upper dermis containing nests and cords of nevus cell without junctional activity. The skin lesion was totally removed by surgical excision on biopsy.

PURPOSE: The education of the patients is an effective component of comprehensive care, especially in patients with epilepsy. We developed an epilepsy educational program designed to improve the knowledge and understanding of the natural clinical course, the treatment, and prognosis of epilepsy. We evaluated the efficacy of this educational program to epilepsy patient's knowledge of their disorder and quality of life. METHODS: We studied 224 patients with epilepsy from Dongsan Epilepsy Center. All patients completed the Knowledge and Quality of Life in Epilepsy-31 (QOLIE-31) questionnaire before a one-day educational program was completed. Six months after the educational program was given, patients completed the same questionnaire. The results of the two surveys were compared. RESULTS: In the initial questionnaire, about 60% of the patients thought that epilepsy is not related with head trauma. About 40% of the patients thought that epilepsy is a genetic disorder. Over 80% of the patients thought that behavior changes are not related to epilepsy. Over 90% of the patients had correct responses about taking antiepileptic drugs. However, only 60% of the patients had their ideas regarding proper social activity correct. After completing the educational course, the results of the follow-up questionnaires were markedly improved concerning the patients' knowledge of epilepsy. In contrast, the quality of life measures changed a little. CONCLUSION: An epilepsy educational program for patients improves their knowledge of epilepsy. This study was performed with only one education workshop, which is not sufficient to improve the quality of life measures. A well-regulated, systematic educational program is needed to efficiently improve the lives of epileptic patients.

To evaluate a new reliable sclerosant of the gallbladder, we attempted gallbladder ablation with 10% phenol, and the results compared with those from using 95% ethanol which had been used previousy as gallbladder sclerosing agent in laboratory animals in other reports. After laparotomy, ligation of the cystic dusts with silk and cannulation of gallbladder with 18 gauge angiocatheter were done. Then, transcatheter administration of two different scleroing agents was performed in 8 rabbits respectively and normal saline in four rabbits as a control. Additionally, preliminary washing with each agent were implemented to prevent the dilutional effect of residual bile and bleeding. All animals survived without complication. Eight animals were used for each agent, four each being sacrified two weeks and six weeks after adminstration of sclerosing agents respectively. In our results, 10% phenol was more effective than 95% ethanol in denuding the gallbladder epithelium and promoting fibrosis of gallbladder wall, And it was relatively safe in regard to the dilutional effect of residual fluid and bleeding during procedure. Toxic effects on the liver evaluated by examination of histologic specimen were non-specific except for edematous swelling on some cases, which had also been observed on others including control group. 10% phenol can be considered to be a promosing sclerosant for gallbladder ablation, but further study of its toxicity is needed before its application on human gallbladder.

Ganglioneuroma is an uncommon benign tumor and arise from neural crest cells or sympathetic and peripheral nerves. A 13-year-old boy was referred to our institute and presented with three-day history of right upper extremity weakness associated with neck pain for nearly one month. Magnetic resonance imaging showed right side dumbbell shaped extramedullary lesion at the C2-3 level extending outside through neural foramen. Paraspinal and posterior neck mass, cafe au lait spot was identified. We performed surgical decompression of the spinal cord by resection of intradural portion mass. Histopathological diagnosis was ganglioneuroma.

Objective: To report on combined surgical and/or endovascular procedures for cerebrovascular disease in a hybrid operating room (OR). Methods: Between October 2016 and June 2020, 1832 neurosurgical procedures were performed in a hybrid OR. Our institution’s hybrid OR consists of a multi-axis robotic C-arm monoplane digital subtraction angiography (DSA) system with an operating table, 3D-rotational DSA, cone-beam computed tomography (dyna CT), and real-time navigation software. Procedures were categorized into six categories according to purpose: (1) simple diagnosis and follow-up, (2) simple endovascular procedure, (3) combination of surgery and endovascular procedures, (4) rescue surgery after endovascular procedures, (5) frameless stereotactic procedure, and (6) other surgeries requiring C-arm. Results: Of 1832 neurosurgical procedures in the hybrid OR, 1430 were simple diagnosis and follow-up cases, 330 simple endovascular procedures, 8 combination of surgery and endovascular procedures, 15 rescue after endovascular procedure, 40 frameless stereotactic procedures, and 9 other surgeries. Eight cases of combination of surgery and endovascular procedures, safely performed without wasting time on patient transfer, were performed in seven bypass end endovascular procedures and one case of bow-hunter syndrome in complex cerebrovascular disease. After embolization, craniotomy (or craniectomy) and intracerebral hemorrhage removal were performed in eight patients in-situ. Of the 40 frameless stereotactic procedure, 37 were extraventricular drainage before/after coil embolization in subarachnoid hemorrhage patients. They all mounted conduits in their planned locations. Conclusions A hybrid OR for combined endovascular and surgical procedures represents a safe and useful strategy for cerebrovascular disease. In hybrid ORs various neurosurgical procedures can be safely and conveniently performed. Hybrid OR will pioneer a new era in neurosurgical procedures.

A 57-year-old man complained of severe lower back pain and radicular pain in both legs for 1 week after falling from a ladder. Magnetic resonance imaging (MRI) of the spine showed a subdural hematoma (SDH), which was surgically removed. The patient had no back pain or the radicular leg pain at 2 weeks post-surgery. However, he complained of diffuse headaches upon follow-up. Brain computed tomography (CT) and MRI revealed an intracranial SDH, which was immediately removed by surgery. During his 1-year follow-up, he reported that the pain had resolved without recurrence. Simultaneous spinal and intracranial SDH are rare and no standard treatment exists for this condition. This case suggests that it is possible that an intracranial SDH can migrate into the cerebrospinal fluid (CSF) space through an arachnoid tear. CSF circulation allows the intracranial SDH to enter subarachnoid spaces encasing the spinal cord. In order to prevent irreversible damage, surgical intervention should be considered for case of spinal SDH with progressive neurological deficits.
