Journal of the Korean Medical Association 2002;45(2):176-190
Distinguishing epileptic seizure from non-epileptic seizure is a common diagnostic problem. Neurogenic or cardiac syncope can appear similar to atonic and even convulsive seizures. Classic migraine and transient ischemic attacks may also resemble epileptic seizures. Sleep disorders including REM sleep behavior disorder, nocturnal paroxysmal dystonia, and narcolepsy likewise simulate an epileptic seizure. Movement disorders such as paroxysmal dyskinesia can be misinterpreted as epileptic seizures (reflex epilepsy or myoclonic seizures). Psychogenic seizures are often misdiagnosed as an intractable epilepsy. Prior to the definitive diagnosis of epilepsy, possible non-epileptic seizures should be excluded. For the correct decision, a thorough and systematic history taking is important. In addition, EEG, pseudoseizure induction test, head-up tilt test, EKG, sleep studies, and video-EEG monitoring may be necessary. Misdiagnosis of non-epileptic seizures as epilepsy may result in unnecessary anti-epileptic drug use. At the same time, we should let the patients understand what the epilepsy is and that epilepsy is a treatable disease.

Background: If phototoxic:ity can be predetermined in vitro, the information will aid in prognosticating whether or not caimpounds have a photosensitizing pczrlial. OBJECTIVE: For the evaluation of the phototoxic potentials of reral drugs, we performed the Candida albicans test and the photohemolysis test. METHODS: The Candida altiicans test is based on growth inhibtion of Candida albicans after application of the drug and ultraviolet light A( UVA ) irradiatior and the photohemolysis test is based on hemolysis of red blood cells caused by irradiation ir the presence of photosensitizing compounds. In the Candida albicans test, clear zones around the drug patches were evaluated, which means positive results for the phototoxic potential of the drugs. In the photohemolysis test, the amounts of hemolysis were evaluated by measuring the relar absorbance at 540nm using a spectrophotometer. RESULTS: In the Candida albicans test, ibuprofen, naldix acid, chlorpromazine and thiodiphenylamine showed positive results, whereas others did not the photohemolysis test, griseofulvin, ibuprofen and nalicdixic acid showed increased amounts hemolysis at UVA and ultraviolet light B(UVB) irracliation, and chlorpromazine, thiodiphenylaiair, chlorothiazide and piroxicam showed increased amounts of hemolysis at UVA irradiation only. CONCLUSION: The results showed that both methods were goodness screening tests for demonstrating the phototoxicity of therapeutic drugs.

5.Clear Cell Ependymoma.

Korean Journal of Pathology 1997;31(4):383-387
The clear cell variant of ependymoma is a rare, recently described, intracranial tumor which is composed of clear neoplastic ependymal cells. Clear cell ependymomas may share characteristic histologic features of oligodendrogliomas or central neurocytomas; striking nuclear uniformity, perinuclear halos, and numerous angulated capillaries. In contrast to oligodendrogliomas, however, clear cell ependymomas are noninfiltrating tumors with sharp boundaries. Perivascular pseudorosette formation is frequent. Oligodendrogliomas are usually nonreactive for GFAP compared to diffuse immunoreactivity of clear cell ependymoma. Central neurocytomas may also be differentiated by their immunoreactivity for synaptophysin. This is a case of clear cell ependymoma in a 40-year-old man. By computed tomography and magnetic resonance imaging scans, a well circumscribed cystic tumor with mural nodule was demonstrated in the right frontal lobe. It was 6cm in diameter and well enhanced. Histologically, it was sharply demarcated from the brain parenchyma. The cystic wall was lined by atypical ependymal cells, which "transformed" to clear cells in the solid area. The cells had uniform nuclei and perinuclear halos. Mitotic figures and necrotic foci were focally present. The cells were immunoreactive for glial fibrillary acidic protein (GFAP), while synaptophysin was negative. Electron microscopy revealed densely packed polyheadral cells with scant organelles and well developed intercellular junctions.

6.The Effect of Alcohol on the Blood Lipid Level of Korean Adult Men.

Korean Journal of Preventive Medicine 1992;25(1):44-52
This study was conducted to evaluate the relations between alcohol intake and blood lipid level in a group of 1,138 Korean adult men, ages 20 to 69 years. Total number of each of a variety of drinks in the previous two weeks was obtained by questionnaire and converted into grams of alcohol consumed in a week. The levels of blood lipid such as Cholesterol, HDL-Cholesterol, Triglyceride and LDL-Cholesterol were examined by enzyme method. We also observed the effects of various variables such as age, body mass index, smoking, exercise and blood pressure on blood lipid level. The results obtained were as follows; 1. Average weekly alcohol intake was 129.0+/-167.4 gm and that of 30-39 age group was the highest as 149.3+/-170.4gm. 2. Levels of Cholesterol, Triglyceride and LDL-Cholesterol tended to increase with increasing age, but level of HDL-Cholesterol showed no significant relationship with age. 3. The positive linear regressions of alcohol intake on HDL-Cholesterol and Triglyceride were noted statistically significant. 4. Multiple regression analysis demonstrated that the effect of alcohol on HDL-Cholesterol and Triglyceride was statistically significant and the contribution rates were 5.0% and 0.8%, respectively. And, in the case of HDL-Cholesterol, the alcohol intake was the most significant independent variable.

7.Spontaneous Hemarthrosis of the Knee in the Elderly.

The etiology of spontaneous hemarthrosis of the knee joint in elderly pattents is still unknown. This report discusses seven spontaneous hernarthroses, three that were managed witla conservative measures such as aspiration, rest and knee immobilization because of poor general condition and four in which arthroscopic evaluation and treatment were performed. These patients were elderly indi.viduals without an obvious history of trauma. The roentgenograms of each involved knee demonstrated degenerative osteoarthritic changes of knee joint. Arthroscopic examination revealed denuded articular cartilage and subchondral bone exposure in four operative cases and degenerative meniscal tear in one case of four. These patients underwent mthroscopic debridement and did not experience recurrenees of the hemarthrosis. We think that the origin of the bleeding was most likely from the subchondral cancellous bone which was exposed due to degenerative change of the knee joint and the senile changes of the vessels around the knee joint with aging process may contribute the spontaneous bleeding into the knee joints.

Traumatic anterior shoulder dislocation combined with scapular fracture in elderly patients is relatively rare. In this case, a patient visited Emergency Room of Dong-A University Hospital for shoulder pain after falling off a ladder. Radiographs demonstrated anterior shoulder dislocation with displaced Ideberg type IIb scapula (glenoid fossa) fracture combined with a large rotator cuff tear on magnetic resonance imaging. We performed arthroscopic rotator cuff repair, but a large fragment in the inferior glenoid was left untreated. At the 1 year follow-up visit, the pain visual analogue scale of the patient was 2, the American Shoulder and Elbow Society score was 88 and the patient had gained nearly full range of motion without any apprehension.
