We report 2 cases of pediatric DNTs which presented with intractable seizures and no other associated neurologic abnormalities. They showed typical appearance of DNTs on neuroimaging and histopathology. Most patients with DNT can be cured by surgical treatment with exellent outcome and do not need ratio- or chemotheraphy. This study indicates that it is quite important to consider DNTs as one of differential diagnoses in patients with intractable seizures especially when they present only with seizures without other neurologic symptoms.

BACKGROUND: Cardiovascular disease is the major cause of morbidity and mortality. It is well known that androgen and sex hormone-binding globulin(SHBG) in women were associated with risk factors for cardiovascular disease such as obesity, central fat accumulation and atherogenic lipid profile. High resolution B-mode ultrasonography can visualize directly both luminal and vessel wall characteristics, and ultrasonic measurement of carotid intima-medial thickness(IMT) can be used to investigate the atherosclerosis of coronary, cerebral and peripheral arteries. The aim of this study was to evaluate the relationship between the serum dehydroepiandrosterone sulfate(DHEA-S) and SHBG, and body fat distribution pattern, cardiovascular risk factor and carotid atherosclerosis in women. METHODS: Blood pressure, fasting serum glucose, insulin, lipid profile, SHBG and DHEA-S were measured. Body fat distribution pattern was assessed by waist to hip ratio, waist to thigh ratio and subscapular to triceps skin fold thickness ratio, faf mass measured by bioelectric impedance analyzer, subcutaneous fat area, visceral fat area, and visceral to subcutaneous fat area ratio(VSR) at the level of umbilicus using the computed tomography. The IMT of the carotid artery was measured by high resolution B mode ultrasound as a marker of atherosclerosis. RESULTS: 1) There was no significant difference of age-adjusted values of carotid IMT among subjects with NGT(0.426+/-0.09mm), IGT(0.46+/-10.09mm) and NIDDM(0.453+/-0.11mm). 2) In postrnenopausal women, carotid IMT was greater(0.484+/-0.11mm, p=0.05) than premenopausal women(0.426+/-0.08mm), but it was not significant after age adjustment. Serum SHBG and DHEA-S levels in postmenopausal women were significantly lower(p<0.05) than premenopausal women, but they were not significant after age adjustment. 3) Carotid IMT was significantly correlated with age(r=0.37, p<0.01), fasting serum glucose (r=0.32, p<0.01), total cholesterol(r= 0.25, p<0.05), LDL-cholesterol(r=0.26, p<0.05), visceral fat area(r=0.35, p<0.01) and VSR(r=0.31, p<0.05). 4) By the stepwise multiple regression analysis, carotid IMT was positively and significantly associated with age(p<0.01) and serum DHEA-S concentration(p<0.05) in dent of age, body mass index, waist to hip ratio, fasting serum glucose. CONCLUSION: Carotid IMT was associated with age and serum DHEA-S concentration in women without cardiovascular disease. Therefore, serum DHEA-S may be one of risk factors for cardiovascular disease in women. However, we could not conclude its cause-result relationship because of cross sectional nature of our study, and prospective study will be needed.

Human membranous nephropathy (MN) is morphologically characterized by subepithelial immune complex deposits and progressive thickening of glomerular basement membranes (GBM). Studies have suggested that the enhanced secretion of classical and novel type IV collagen chains in MN contributes to spike formation and the novel type IV collagen chain is particularly related to thickening of GBM. It is unclear whether the increased accumulation of extracellular matrix (ECM) proteins in GBM is due to the increased mRNA expression for type IV collagen in glomerular visceral epithelial cells (GECs). To answer this question, we analyzed seven renal biopsies of patients with idiopathic MN using in situ hybridization. In MN, the number of GECs expressing mRNA for alpha1(IV) collagen was 2.82+/-1.80/glomerular cross section (gcs), and the number expressing mRNA for alpha4(IV) collagen was 8.42+/-2.85/gcs. The number of GECs expressing mRNA for alpha4(IV) collagen was significantly larger than that of alpha1(IV) collagen mRNA. The expression of mRNA for these ECM proteins in normal controls was negligible. These results suggest that subepithelial immune complexes stimulate the gene expression of alpha1(IV) collagen and alpha4(IV) collagen in glomerular GECs which, in turn, increase the secretion of ECM proteins and contribute to the thickening of GBM in MN.

PURPOSE: Interferon is a widely used treatment for chronic hepatitis B in children. However, additional treatment options are needed because more than 50% of hepatitis B patients are unresponsive to interferon. Although lamivudine is widely used to treat hepatitis B, there are few studies on the effect of lamivudine in hepatitis B patients unresponsive to interferon. METHODS: Eight interferon unresponsive patients (6 males and 2 females) were treated with lamivudine (3 mg/kg/day, maximum 100 mg/day) from 6~12 months after interferon treatment was discontinued among 33 children with chronic hepatitis B. They were treated with interferon (interferon alpha-2b, 10 MU/m2 or pegylated interferon 1.5 microgram/kg) for 6 months from January 2000 to December 2007 at the Pusan National University Hospital. The medical records were analyzed retrospectively. RESULTS: The age at treatment with interferon and lamivudine was 4.9+/-3.1 and 6.1+/-3.2 years, respectively. The serum ALT level before treatment with interferon was 148.1+/-105.8 IU/L and the log HBV-DNA PCR mean value was 6.95+/-0.70 copies/mL. The serum ALT level after treatment with interferon was 143.1+/-90.4 IU/L and the log HBV-DNA mean PCR value was 6.46+/-2.08. HBeAg negativization occurred in 2 patients. For all patients, normalization of the serum ALT levels and HBeAg seroconversion (except 2 patients with HBeAg negativization) occurred at 7.4+/-2.1 and 7.9+/-2.1 months respectively after lamivudine treatment. The HBV-DNA PCR became negative in 7 patients (87.5%) at 2.4+/-2.8 months. Complete response was achieved in 7 patients and no recurrence was observed in 2 patients for 3 years after the completion of treatment. Five patients are still under treatment for a mean treatment duration of 24.4+/-9.1 months. In one patient, viral breakthrough occurred and the treatment was stopped. CONCLUSION: The number of patients was small, however, lamivudine treatment in patients with chronic hepatitis B who were unresponsive to interferon was highly effective.

OBJECTIVES: The purpose of this study is to investigate the characteristics of drinking patterns and the prevalence of hazardous drinking and alcohol use disorder with the assessment of alcohol policy needs in community population of urban city in Korea. METHODS: Data was collected from 1,000 residents in a single urban city in Korea, from June 1 to July 31, 2011 by a questionnaire. As research tools, socio-demographic characteristics composed of variables based on study purpose, alcohol problems and alcohol use disorder state scales composed with Alcohol Use Disorder Identification Test(AUDIT) and Cut down, Annoyed, Guilty, Eye-opener(CAGE), and the assessment of alcohol policy needs in community population questions were used. RESULTS: The lifetime experience of alcohol drinking was 97.4%. For the frequency of drinking, 21.9% of population responded 2 to 4 times per weekly. 24.4% of male had one time or more high risk drinking, defined as having four or more drinks in a sitting, per week. 51.6% experienced the first time drinking of alcohol in adolescence. The lifetime prevalence of hazardous drinking and alcohol use disorder were 14.9% and 3.3%, respectively using AUDIT. Alcohol use disorder were 9.6% with the CAGE scale. Problem drinking were 8.4% in this study. They requested the program such as prevention education(57.2%), construction of liaison system to treatment facilities( 50.1%), alcohol counseling and intervention(41.7%), and rehabilitation program(39.8%). CONCLUSIONS: These results demonstrate that alcohol problem and alcohol use disorder were much prevalent, and these problem started in the earlier age. It is necessary to develop an effective alcohol prevention program or policy with considering the needs in community population.

Little is known about platelet dynamics and the effect of antiplatelet therapy in Kawasaki disease (KD). This study sought to define platelet activation dynamics in KD patients by assaying platelet-derived microparticles (PDMPs). We measured plasma PDMPs levels in 46 patients with KD using an enzyme-linked immunosorbent assay (ELISA). Blood samples were collected before, at 2–5 days, and 9–15 days after intravenous immunoglobulin (IVIG) infusion, 2 months and 4–5 months after the onset of KD. We measured PDMP levels in 23 febrile and 10 afebrile control patients. In the acute phase of KD patients, PDMP levels increased significantly after IVIG treatment (12.04 ± 5.58 nmol before IVIG infusion vs. 19.81 ± 13.21 nmol at 2–5 days after IVIG infusion, P = 0.006). PDMP levels were negatively correlated with age and positively correlated with procalcitonin levels in the acute phase of KD. No significant difference was found in PDMP levels between KD patients with and without coronary artery lesion (CAL). Elevated PDMP levels after IVIG therapy significantly decreased below the pre-IVIG level in subacute phase (19.81 ± 13.21 nmol at 2–5 days after IVIG infusion vs. 8.33 ± 2.02 nmol at 9–15 days after IVIG infusion, P < 0.001), and PDMP levels stayed below the pre-IVIG level in the convalescent phase, during which antiplatelet therapy was given. However, PDMP levels rebounded after discontinuing aspirin in 17 patients. In conclusion, enhanced platelet activation was noted before treatment of KD and peaked immediately after IVIG treatment. Recurrent rising of PDMP levels was observed after discontinuing aspirin, although there were no significant differences between the PDMP levels at 2 months after the onset of KD and those at 4–5 months after the onset of the disease.

The anatomy of the arteries distributing to the ocular rectus muscles has not been well known inspite of their importance during opertions. Eighty orbits of Koreans were dissected under the surgical microscope to find out the entering point and its distribution of each rectus artery. The average numbers of the branches of the artery that piercing the supenor, lateral, medial, and inferior recti were 4, 7, 7 and 6 respectively. The supenor rectus artery tended to pierce the posterior middle one third of the muscle; the medial and lateral rectus arteries tended to pierce the posterior two thirds of the muscles; and the inferior rectus artery tended to pierce the medial two tbrds of the muscle. The arterial branches piercing the anterior one third of the superior rectus were less than 1%, and those of the lateral, medial, and inferior recti were 5%, 10% and 15% respectively. The relationships between the artery and nerve differed in each muscle.

Intactness of arterial supplies is necessary for the external ocular muscles to move properly, however the anatomy of the ocular muscular arteries has not been clarified Therefore, 80 orbits of Koreans were dissected under the surgical microscope and the origins of the rectus arteries were observed. The average numbers of the arising site of the artery to the superior rectus, the lateral rectus, the medial rectus, and the inferior rectus were 1.7, 1.2, 2.2 and 1.1, respectively. The superior rectus artery arose from the superolateral muscular artery in 33.3%. The lateral rectus artery arose from the superolateral muscular arterey in 43.8%, from the inferior muscluar artery in 24.8%. The medial rectus artery arose from the inferior muscular artery in 43.1%, from the superomedial musculal artery in 16.8% and from the ophthalmic artery as a solitary branch in 32.9%. The inferior rectus artery arose from the inferior muscular artery in 83.1% and from the inferolateral muscular artery in 13.5%.
