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.

Studies on hepatic tuberculosis are rare in Korea except several case repots. This is the first report on hepatic tuberculosis confirmed by the peritoneoscopic liver biopsy in Korea. A 43-year-old man was admitted due to high fever and cough for l0 days. On physical examination moist rale was audible on the both lower lung fields and hepatomegaly was noted. Chest X-ray revealed multiple fine granularity scattered uniformly throughout the both lung fields compatible with miliary pulmonary tuberculosis. On blood chemistry, SGOT, SGPT and alkaline phosphatase were elevated. Peritoneascopy revealed multiple yellowish-white small nodules evenly acattered on the entire surface of the both lobes of the liver and the needle biopsy of the liver showed chronic granulomatous inflammation with multinucleated giant cells and caseous necrosis consistent with hepatic tuberculosis. The patient was treated with antituberculous medications. Chest X-ray 6 months after treatment revealed completely healed miliary pulmonary tuberculosis and on blood chemistry 200 days after therapy SGOT, SGPT and alkaline phosphatase were within normal limits.

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: To evaluate the clinical and electrophysiological characteristics of malformation of cortical development (MCD) with epilepsy. METHOD: We studied clinical and electroencephalographic (EEG) features of 54 childhood epilepsy patients with MCD diagnosed by magnetic resonance imaging (MRI) and pathologic examinations. RESULTS: 1) Bilateral diffuse MCD's were in 5 patients, bilateral focal MCD's were in 8, unilateral diffuse MCD's in 7, and unilateral focal MCD's were noted in 34 patients. 2) Partial seizures were manifested in 35 patients, and 4 of them evolve to infantile spasm (IS), isolated IS was noted in 15 cases, and generalized seizures were noticed in 2 cases 3) Asymmetric EEG backgraound slowing was noted in 30 patients, and 29 patients (96.7%) had MCD's in abnormal side of brain. 4) Polymorphic slowing was noted in 36 patients, and 28 cases (77.8%) had MCD's in those area. 5) Sensitivity of partial epileptiform discharges (ED's) for MCD was 79.6%, but specificity was 68.5%. 6) Localized paroxysmal fast activity was noted in 16 cases (29.6%), and specificity for MCD was 90.7%. 7) Spindle shaped fast activity was noted in 8 patients (14.8%), and its specificity was 100%. 8) Thirty-one cases (57.4%) were intractable to antiepileptic drugs (AED's). Seventeen cases of them were treated by ketogenic diet, and 12 patients (66.7%) were completely controlled. Among 12 cases of surgical resection, 11 patients (91.7%) became seizure free for 6 months to 2 years. 9) In pathologically confirmed cases, EEG sensitivity for MCD lesion was 100%, but sensitivity of MRI was 69.2%. CONCLUSION: EEG is most sensitive diagnostic tool for MCD in childhood epilepsy. and many of intractable epilepsy could be controlled by ketogenic diet and surgery.

PURPOSE: To evaluate the differential clinical & electroencephalographic characteristics between benign childhood epilepsy with occipital paroxysm (BCEOP) and symptomatic occipital lobe epilepsy (SOLE). METHODS: Nine patients of BCEOP and seven patients of SOLE diagnosed at the department of pediatrics and epilepsy center in Inje University Sang-gye Paik Hospital from March 1992 to June 1998, were studied for the determination of differential characteristics between the two groups. Clinical features, EEG characteristics, MRI findings, associated conditions, and prognosis were investigated and compared between these groups. RESULT: 1) Male : female ratio was 1 : 2 in BCEOP and 1 : 2.5 in SOLE. 2) Seizure onset age was older in SOLE as compared with BCEOP. 3) There was no significant difference in seizure types between two groups. 4) Visual aura could be elicited in 5 patients (55.6%) in BCEOP, and 3 patients (42.9%) in SOLE. 5) Ictus emeticus was only noted in 4 patients (44.4%) of BCEOP. 6) Migraine was associated only in 3 patients of BCEOP. 7) Background EEG abnormality was more frequently associated in SOLE than BCEOP. 8) Seizure control was inefficient only in 3 patients (42.9%) of SOLE, and all patients with BCEOP were successfully treated with antiepileptic drugs. CONCLUSION: SOLE showed higher seizure onset age, less frequent association of ictus emeticus and migraine, more frequent background EEG abnormalities and more medical intractability to antiepileptic drugs than BCEOP.

BACKGROUND: In the previous studies, we identified that the interferon-gamma activated sequence (GAS) in the 5-flanking region of rat ICAM-1 gene is major element for interferon-y-inducible expression of the gene in rat thyroid cells, FRTL-5. We here, investigated the role of transcriptional coactivators, CBP (CREB binding protein) and CIITA (class II transactivator) in the modulation of the activity of GAS which could interacts with signal transducers and activators of transcription-1 and 3 (STAT1 and STAT3). METHODS: The expression of CBP RNA and protein were quantitated in FRTL-5 after stimulation with interferon-y (IFN-gamma), thyroid stimulating hormone (TSH), forskolin and methimazole. Direct association of CBP with STAT were analyzed by irnmunoprecipitation. The transcriptional roles of CBP and CIITA in the regulation of GAS were assessed by the cotransfection with their expression vectors with reporters; 5-deletion constructs of rat ICAM-1 promoter or 8xGAS-luc constructs, into FRTL-5 thyroid cells. RESULTS: The level of CBP RNA and protein were not changed by the treatment with TSH, IFN-y, forskolin and methimazole in FRTL-5, FRT and BRL liver cells. The CBP could be directly associated with STAT1. Furthernmore, the overexpression of CBP significantly increases the both promoter activities; rat ICAM-1 gene promoter which has GAS element and 8xGAS-luc cassette constructs. However the cotransfection of CI1TA decreased the constitutive and CBP-mediated transactivation of rat ICAM-1 promoter and SxGAS-luc cassette constructs. CONCLUSION: We identified that the two transcriptional coactivators; CBP and CIITA has differential roles in the regulation of transcriptional activity of GAS drived promoter. CBP increases the GAS activity through the direct binding with STATl, but CIITA inhibited the CBP-mediated transactivation of GAS activity.

OBJECTIVES: Coblation is operated in low temperature, so it is proposed that tonsillectomy with coblation involves less postoperative pain and allows accelerated healing of the tonsillar fossae compared with other methods involving heat driven processes. However, the results of the previous studies showed that the effect of coblation tonsillectomy has been equivocal in terms of postoperative pain and hemorrhage. Though, most of the previous studies which evaluated coblation tonsillectomy were performed in children. Recently, electrocautery tonsillectomy has been used most widely because of the reduced intraoperative blood loss and shorter operative time compared to other techniques. This prospective study compared intraoperative records and postoperative clinical outcomes in adolescents and adults following coblation and electrocautery tonsillectomies. METHODS: Eighty patients over 16 years of age with histories of recurrent tonsillitis were enrolled. The patients were randomly allocated into coblation (n=40) and electrocautery tonsillectomy groups (n=40). All operations were performed by one surgeon who was skilled in both surgical techniques. Intraoperative parameters and postoperative outcomes were checked. RESULTS: Postoperative pain and otalgia were not significantly different between the two groups; however, there was a tendency towards reduced pain and otalgia in the coblation group. More cotton balls for swabbing the operative field were used introoperatively in the electrocautery group (P=0.00). There was no significant difference in postoperative hemorrhage, wound healing, commencement of a regular diet, and foreign body sensation between the groups. CONCLUSION: Only cotton use, which represented the amount of blood loss, was less in the coblation tonsillectomy group. Coblation tonsillectomy warrants further study with respect to the decreased postoperative pain and otalgia.

Axenfeld-Rieger syndrome is a rare autosomal dominant inherited developmental disorder characterized by ocular and systemic abnormalities. In ocular anomaly, it includes a prominent and anteriorly displaced Schwalbe line and an iridocorneal synechiae, iris hypoplasia, corectopia and secondary glaucoma. Extraocular developmental abnormalities of the syndrome are hearing loss, congenital heart disease, dental anomalies, developmental delay, and a characteristic facial appearance. We herein reported a familial case of Axenfeld-Rieger syndrome that had a mitral valve prolapse with severe mitral regurgitation finally requiring mitral valve replacement.
