Autosomal dominant nocturnal frontal lobe epilepsy(ADNFLE) is a recently identified partial epilepsy. This disorder is characterized by a variable age of onset(mostly in childhood), autosomal dominant inheritance, clusters of brief frontal nocturnal seizures, negative findings on neuroimaging, and fairly good prognosis. Carbamazepine is known to be the most useful drug in this type of epilepsy. We experienced a case of 5-year-old boy who had unusual arousal and irritability every night for 3 years and had sharp & wave discharges from frontal lobe region in long-term video-EEG monitoring, who was suspected as an autosomal dominant nocturnal frontal lobe epilepsy. We report a case with a brief review of literatures.

BACKGROUND: Leptin, the product of ob gene, is an important circulating hormone for the regulation of homeostasis of body weight and enegy expenditure. There was a previous reports that thyroid hormone is one of regulating factors of leptin gene expression in vitro. The aim of this study was designed to evaluate the role of thyroid hormone levels in the regulation of circulating leptin concentrations in human. METHODS: A total 16S subjects were studied; 76 patients with Graves disease, 49 patients with Hashimoto disease and 43 control sujjects. The correlation between thryoid hormone and leptin levels were analyzed and serum leptin levels were compared among the groups which was classified by thyroid functional status. Serum leptin concentratios were measured by radioimmunoassay. RESULTS: There were no significant differences in serum leptin levels between the groups of control, Graves disease and Hashimoto disease. The hypothyroid groups of Graves disease which was induced by excessive antithyroid drug treatment showed significant low levels(5.6 +/-2.8 ng/mL) compared to control(9.6 +/- 5.2 ng/ml) and thyrotoxic groups(10.0 +/- 5,0 ng/mL) CONCLUSION: The hypothyroid patients showed low levels of serum leptin concentrations it may indicate that thyroid horrnone play a role in the appropriate secretion of leptin in human.

The Changes of soluble Fas levels in Patients with Autoimmune Thyroid Diseases BACKGROUD: Apoptosis was observed in thyroid tissue from Hashimoto disease but not those from Graves disease. Recently Fas and Fas ligand interactions among thyrocytes were suggested to development of clinical hypothyroidism in Hashimoto disease.Soluble Fas produced as the form lacking the tranmembrane domain due to alternative splicing, is supposed to inhibit Fas-Fas ligand interaction and blocks Fas mediated apoptosis. METHODS: In tbis study, we measured serum soluble Fas to determine the possible involvement of this molecule in the autoimmune thyroid disease by enzyme linked immunosorbant assay in 29 patients with Graves disease, 30 patients with Hashimotos disease and 19 normal controls. RESULTS: Compared with normal subjeets (4.26 +/- 1.00 U/mL), soluble Fas was not increased in patients with Graves disease (4.23 +/- 1.14 U/mL, p>0.05) but it was increased in throtoxic Graves patients (4.70 +/- 1.26 U/mL, p<0.05) compared to euthyroid Graves (3.72 +/- 0.73 U/mL, p<0.05) and normal subjects (4.26 +/- 1.00 U/mL, p<0.05). The euthyroid and hypothyroid patients with Hashimoto disease showed low soluble Fas levels, 2.94 +/- 0.54 U/mL and 2.74 U/mL, respectively compare to the patients with Graves disease and normal subjects. The thyroid hormone levels to (T3 T4 and free T4) showed positive correlation with the serum titers of antithyroid autoantibodies, antithyroglobuin antibodies, antiperoxidase antibodies and thyrotropin binding inhibitor immunoglobulins. CONCLUSION: We found that the patients with thyrotoxic Graves disease had increased level of serum soluble Fas and the patients with Hashimoto disease showed low levels of soluble Fas compared to normal controls. Increased soluble Fas in Graves disease suggests increased expression of alternatively spliced Fas mRNA variant and decreased soluble Fas in Hashimoto disease suggests decreased Fas mRNA variant and increased full length membrane Fas, so these findings are related to the promotion of apoptosis of thyroid cells during autoimmune reaction in Hashimotos disease.

Peri-vater divertieula may interfere with the normal flow of biliary and pancreatic secretion, thus leading to pancreatobiliary diseasa and the very presence of juxtapapillary diverticulum makes cannulation technically difficult and contributes to the low success rate. In this present series, the relationship between duodenal diverticula and age, sex, and biliary-pancreatic pathology was stud.ied in 1400 patients examined with ERCP. The results are as follows. 1) Duodenal diverticula was demonstrated in 73 of 1400 patients(5, 2%). 2) The incidence of duodenal divertieular increased with age and they were more frequent in men. 3) The cannulation of one or both duct system was suecessful in 69 of the 73 patients, the success rate was 94. 5%. 4) The biliary pathology was found in 41 of the 73 patients and the pancreatic pathology in 6 of the 73 patients. The rnost common finding was biliary calculi which were demonstrated in 35 patients(47. 9%).

The mortality of patients with brain abscess has decreased significaltly. This has been attributed to improved diagnostic imaging, the evolution of neurosurgical techniques and understanding of intracranial pressure pathophysiology, greater critical care understanding, and newer antibiotics. However, the mortality associated with intraventricular rupture of brain abscess remained consistently high at or above 80% once identified. A case of intraventicular rupture of thalamic abscess with good quality of survival is presented based on aggressive 4-component therapeutic plan used. The four components are 1) extraventricular drainage for 6 weeks, 2) lavage of the ventricular system using closed irrigation system, 3) intravenous antibiotics, 4) intraventricular gentamicin and vancomycin, twice and once daily, respectively.

PURPOSE: Ketogenic diet has been frequently used in the treatment of intractable childhood epilepsy since proven strong antiepileptic effects. Because of prolonged maintenance of high fat diet, long-term side effects of hyperlipidemia and atherosclerosis has been concerned, but there are no sufficient data revealing lipid profile from ketogenic diet. This study is intended to investigate the changes of lipid profiles in patients with ketogenic diet. METHODS: Sixty-six children (0.8-14.7 yrs, mean age 4.6+/-3.6 yrs, 33 males and 33 females) with intractable epilepsy treated with the classic (4:1) ketogenic diet were studied at Inje University Sang-gye Paik Hospital, from January 1997 to July 2001. Follow-up period was more than 1year (range:1-2 yrs). Cholesterol, HDL-cholesterol and Triglyceride (TG) concentrations were measured at 1 day, 7 days, 6 months, 12 months, 18 months and 24 months, and LDL-cholesterol concentrations were measured. RESULTS: 1) Total cholesterol concentrations were significantly increased from 7 days to 24 months after ketogenic diet than that before ketogenic diet (p<0.05). 2) HDL-cholesterol concentrations were not significantly changed for 2 years. 3) LDL-cholesterol concentrations were significantly increased at 6 months (119.9 mg/dL, p<0.05), and 24 months (128.0 mg/dL, p<0.05). 4) TG concentrations were significantly increased at 7 days (164.9 mg/dL, p<0.05), 6 months (209.7 mg/dL, p<0.01), and 12 months (192.0 mg/dL, p<0.01), and were normalized at 18 months, 24 months. CONCLUSION: Most of lipid profiles were significantly changed during ketogenic diet. Long-term complication for cardio-vascular diseases should be further investigated.

PURPOSE: To evaluate myocardial conductivity to understand cardiac involvement in patients with mitochondrial disease. METHODS: We performed retrospective study on fifty-seven nonspecific mitochondrial encephalopathy patients with no clinical cardiac manifestations. The patients were diagnosed with mitochondrial respiratory chain complex defects through biochemical enzyme assays of muscle tissue. We performed standard 12-lead electrocardiography (ECG) on all patients. RESULTS: ECG abnormalities were observed in 30 patients (52.6%). Prolongation of the QTc interval (>440 ms) was seen in 19 patients (33.3%), widening of the corrected QRS interval in 15 (26.3%), and bundle branch block in four (7.0%). Atrioventricular block, premature atrial contraction and premature ventricular contraction were seen in two patients each (3.5%) and Wolff-Parkinson-White syndrome in one patient (1.8%). CONCLUSION: Given this finding, we recommend active screening with ECG in patients with mitochondrial disease even in patients without obvious cardiac manifestation.

PURPOSE: Twenty percent or more of children with epilepsy may have attention deficit hyperactivity disorder (ADHD). The treatment of ADHD with epilepsy has been an important clinical issue. The aim of this study is to investigate the efficacy and safety of methylphenidate in children with epilepsy and ADHD. METHODS: The subjects were 38 children with ADHD accompanied by epilepsy diagnosed at Department of Pediatrics and Epilepsy Center, Sanggye Paik Hospital. They were examined with IQ testing and Conners scales at baseline before using methylphenidate, and follow-up study was repeated 1 year after methylphenidate. Efficacy was determined by Conners scales and IQ score results. Safety was determined by measuring changes in seizure frequency, and electroencephalographic findings. RESULTS: According to their parents and teachers' reports, methylphenidate improved ADHD symptoms in 24 children (63.2%). Three of them (7.9%) showed significant improvement in IQ scores and 7 children (18.4%) revealed significant improvement in cognitive function with rising IQ scores between 10 and 15 points. There were no worsening in seizure frequency, and electroencephalographic findings after methylphenidate. CONCLUSION: Methylphenidate is effective and safe treatment in children with epilepsy and ADHD, showing significant benefit on children's behavior and academic improvement in many cases.

BACKGROUND: Accurate quantitative testing of HBV DNA is very important for choosing antiviral treatment targets and evaluating treatment response in chronic HBV patients. We evaluated the performance of LG AdvanSure HBV Real-Time QPCR kit (LG) utilizing real-time quantitative PCR. METHODS: The LG kit was conducted for 201 chronic hepatitis patients undergoing treatment at the Korea University Ansan hospital and 48 normal control volunteers. The precision, limit of detection, sensitivity, and specificity of LG Kit were evaluated. Correlation analysis was done with Abbott Real Time HBV kit (Abbott) and the Cobas Amplicor HBV Monitor kit (Cobas) and the concordances rate of the three methods were calculated. RESULTS: The LG assay showed linear range of detection from 10(2) to 10(6) and coefficient of variation (CV) was 1.10~0.52% at > or =1,000 IU/mL and 1.19% at 100 IU/mL. The coefficient of determination for precision analysis was 0.997. The limit of detection for detection of 95% of positive samples was 9.71 IU/mL (54.4 copies/mL). In 201 clinical samples, the log HBV DNA/ml showed good correlation between Roche vs Abott, Roche vs LG and Abott vs LG, respectively (n=105, 108, 133, r2=0.91, 0.89, 0.94, P<0.0001). The overall concordance rate of three methods were 79.1% (159/201), 82.1% (165/201), and 85.1% (171/201), respectively, showing no stastically significant difference (P>0.05). CONCLUSION: LG AdvanSure HBV Real-Time QPCR kit showed outstanding precision, linearity, limit of detection, good correlation with previous methods, and is a valuable tool in treatment monitoring of chronic HBV infections.

BACKGROUND: Since the human genome project was completed in 2003, there have been numerous reports on cancer and related markers. This study was aimed to develop a system to extract automatically information regarding the relationship between cancer and tumor markers from biomedical literatures. METHODS: Named entities of tumor markers were recognized by both a dictionary-based method and machine learning technology of the support vector machine. Named entities of cancers were recognized by the MeSH dictionary. RESULTS: Relational and filtering keywords were selected after annotating 160 abstracts from PubMed. Relational information was extracted only when one of the relational keywords was in an appropriate position along the parse tree of a sentence with both tumor marker and disease entities. The performance of the system developed in this study was evaluated with another set of 77 abstracts. With the relational and filtering keyword used in the system, precision was 94.38% and recall was 66.14%, while without the expert knowledge precision was 49.16% and recall was 69.29%. CONCLUSIONS: We developed a system that can extract relational information between a tumor and its markers by incorporating expert knowledge into the system. The system exploiting expert knowledge would serve as a reference when developing another information extraction system in various medical fields.
