Many types of meniscal anomalies were reported. Authors found a double-layered lateral meniscus, with one meniscus overlying another. The 39-year old male patient had torn medial and lateral menisci. We performed partial medial and lateral meniscectomy, and incidentally found that lateral meniscus was double-layered. It was characteristic that the upper small accessory meniscus was firmly connected from the posterior horn to middle segments of the lower main meniscus along its peripheral edge. We left it alone. The symptoms were gone, So, it was thought that this anomaly was not related to the patient's symptoms.

BACKGROUND: Methemoglobinemia(MetHb) induced by dapsone overdose is not uncommon in Korea, especially in rural area. For treatment of dapsone-induced methemoglobinemia, methylene blue(MB) and activated charcoal(AC) should be used. To date, no reports have compared the amount of MB used between MB alone with MB & AC combined group(MB+AC). And also between moderate (MetHb<35%) and severe (MetHb>35%) intoxicated group defined by initial MetHb level. Authors hypothesized that less amount of MB can be used if MB and AC was used together and larger amount of MB is necessary to reduce MetHb level to asymptomatic level in severely intoxicated group. METHODS: From Jan 1990 to Dec 1996, a total of 54 patients who received treatment for dapsone intoxication were subject of study, The study was done retrospective chart analysis for initial MetHb level, total amount of MB and AC. Wilcoxon rank sum test and Chi-sqiare test was used to compare the total dosage of MB used for each group. Linear regression analysis was used between initial MetHb and the total amount of MB. Results were considered statistically significant when p<0.05. RESULTS: For MB alone and MB+AC group, the differences in total amount of MB used were statistically significant with mean dosage of 7.14+/-1.1mg/kg and 4.28+/-0.7mg/kg, respectively. And total amount of MB used between moderate and severe intoxicated group, the differences were statistically significant with mean dosage of 5.16+/-1.1mg/kg vs. 10.98+/-1.9mg/kg, respectively. There was significant correlation between initial MetHb level (X) and the amount of methylene blue (Y), Y=0.3X-2.42 (r2=0.41, p=0.0001) in MB alone, Y=0.186X-1.95(r2=0.21, p=0.034) in MB+AC respectively. CONCLUSION: For methemoglobinemia induced by dapsone, total amount of MB can be reduced especially in severe Intoxicated group if AC use was combined in treatment modality. There was significant correlationship between initial MetHb level and total amount of MB used.

Zonisamide was administered to 20 patients with refractory epileptic seizures. The mean duration of the administration was 6 months, and the mean dosage was 7.2 mg/kg/day. The efficacy of zonisamide was rated remarkable in 15% of the cases, improvement in 40%, and no change in 45%. The response rates of zonisamide were 62.5% for myoclonic seizures, 50% for tonic-clonic seizures, 80% for atonic seizures and 33.3% for atypical absence seizures. There was no correlation between the clinical response and dose or serum concentration of the drug. The adverse effects were observed in 35% of the cases which were drowsiness, dizziness, ataxia, nausea, and vomiting. In all cases, however, the administration of zonisamide could be continued.

This study was designed to evaluate the clinical manifestations and results of operative treatment in penile injury during erection. We reviewed 18 cases of penile injury during erection from December 1992 to June 1996. Of 18 patients, 14 patients were treated with early operation, 3 patients with conservative treatment and followup was 1 to 31 months (mean: 14.1 months). Patients age ranged from 23-76 years old (mean: 39.6 years), common cause of the injury was sexual intercourse (8 cases), masturbation (3 cases) and finger-pressure (2 cases) in order. Of 8 patients who occurred during sexual intercourse, 7 patients were married. The injury developed at midnight in 8 cases (44%), early morning in 7 cases (39%) and the other times in 3 cases (~7%). Of 14 patients who received with early operation, 13 patients revealed rapture of the corpus cavernosum and 1 patient revealed rupture of superficial dorsal vein. The site of penile fracture showed proximal shaft in 8 cases (62%), midshaft in 3 cases (23%) and distal shaft in 2 cases (15%) in order. The overall complication rate of early operative treatment was 15% (2 of 13 cases) compared to a complication rate of 100% (2 of 2 cases) for conservative treatment. In conclusion, our experience demonstrates that the most common cause and site of penile injury are sexual intercourse and proximal shaft, early operative treatment would be an effective treatment of penile injury to prevent complications.

Primary disorders of the nervous system admitted to the Pediatric ward of Seoul National University Hospital during 10 years from January 1969 till December 1978 were analysed to observe particularly the annual change of the incidence. Total number of the diseases of the nervous system was 1522, about 20.2% of the total admitted patients during this period. Annual incidence of the diseases of the nervous system was decreasing. It is mainly due to decreased incidence of the infectious diseases, such as tuberculous meningitis, encephalitis and encephalopathy. The most common deseases of the nervous system during the 10 years were tuberculous meningitis 370 cases (24.3%), aseptic meningitis 122 cases (8.0%), grand mal epilepsy 102 cases (6.7%), unspecified convulsion 79 cases (5.2%), bacterial meningitis 77 cases (5.1%), infectious polyneuritis 68 cases (4.5%), encephalitis 63 cases (4.1%), febrile convulsion 59 cases (3.9%), and unspecified encephalopathy 57 cases (3.7%) in the order of frequency. The incidences of tuberculous meningitis was noted in March, April and May, aseotic meningitis in June, July, August and September, encephalitis in September and October, encephalopathy in June, July, and August, and infectious polyneuritis, in July and August. Mumps meningo encephalities predominantly affected male children. Bacterial meningitis was most common before 2 years of age, especially before 6 months, and tuberculous meningitis during second and third year of life. Aseptic meningitis and mumps meningitis wee mots common at 7 years of age. Encephalopathy occured commonly before one year of age, and Reye's syndrome before four years of age. Unspecified convulsion was commonly observeb before 6 months of age, and febrile convulsion before one year. Infectius ployneuritis was common due to meninitis (76 cases) particularly tuberculous meningitis (50 cases), the next was encephalopathy, unspecified (31 cases).

BACKGROUND: Recently elderly people have increased in Korea and increased demands of medical service. This study was carried out to identify diseases and health service utilization patterns of geriatric inpatients to provide better understanding and basis planning to meet the needs of expanding geriatric population. METHOD: We use data of `Patient Survey in Korea` in 1999 and analyzed characteristics of disease structure and utilization patterns of health care service of 54,013 cases of discharged patients aged 65 years or more. RESULT: The proportion of the elderly in total discharged patients is 14.7%. Male to female ratio is 1:1.3 and most common age group was between 65 and 69 years old. 84.2% of elderly patients were admitted at secondary or tertiary health care facilities. The most common disease in geriatric inpatients is malig- nancy in male and vascular disease in female. The average duration of hospitalization is 14.2 days. They stay longer than the nation wide average hospital length and stay longest when they are admitted by mental and behavioral disorders. CONCLUSION: Geriatric patients are admitted mostly with chronic degenerative diseases such as neoplasm and vascular disease. Elders prefer to be admitted to tertiary hospitals and oriental hospitals. They stay more in hospital.

OBJECTIVE: As an electronic health record system is implementing in Korean health care sectors, concerns about key functionalities of electronic health record systems are increasing. The purpose of this study was to identify core functions and set the priority in electronic health record systems under the Korean contexts in order to assure and improve the quality of the systems. METHODS: A survey was conducted using questionnaire developed by the study team based on literature review. The subjects were medical record administrators working at medical record department in general hospitals. RESULTS: The response rate was 59.8%(55/92). The functions which more than ninety percent of subjects responded as necessary right now and/or in near future related to 'drug alert', 'clinical guideline', 'chronic disease management', 'automated real-time surveillance', 'coded data', 'result reporting', 'de-identifying data', 'disease registry', and 'provider-provider communication and connectivity'. CONCLUSION: The results showed the high prioritized functions were decision support and health information/data management.

Magnetic resonance (MR) imaging of thirteen patients with tuberous sclerosis were reviewed. Seven patients underwent computed tomography (CT). The characteristic MR finding of tuberous sclerosis was those of subependymal nodules which were best seen on short repetition time (TR) spin-echo images. Hypointensities within the nodules consistent with calcification were most evident on long TR images. Contrast enhancing lesions, indicative subependymal giant cell astrocytoma, occurred in four cases. Cortical tubers (n=11) and white matter lesions(n=8) exhibited long T1 and T2 relaxation characteristics although reversed pattern was noted in one newborn patients. Cortical tubers and white matter lesions had more irregular shapes in early childhood patients. MR imaging is the sensitive method in detection of gyral tubers and white matter lesions and also valuable in detecting giant all astrocytoma.
