PURPOSE: Attention Deficit Hyperactivity Disorder (ADHD) is known to be more common in children with epilepsy than in the general population. Thirty one to forty percent of ADHD is accompanied with epilepsy. Few studies regarding this matter have been reported in Korea. This study was aimed to evaluate the comorbidity of ADHD in children with epilepsy. METHODS: This is a two center based, retrospective and controlled study. Thirty four ADHD children with epilepsy from Chungbuk National University hospital and 38 ADHD children without epilepsy from Cheonju St. Mary's hospital were recruited from January 2005 to June 2010. RESULTS: In ADHD children with epilepsy, twelve (35.2%) had partial seizures, 11 (32.2%) did generalized seizures and 11 (32.2%) were unclassified. EEG abnormalities were found in the frontal lobe (15 cases), in the central lobe (7 cases), in the temporal lobe (6 cases), and in the occipital lobe (3 cases). In ADHD children with epilepsy, the combined type was major (76.4%) and in ADHD children without epilepsy, the inattentive type was major (50.5%) (P=0.004). Learning disability was mor common in ADHD with epilepsy than in ADHD without epilepsy (P=0.01). CONCLUSION: This study showed that ADHD children with epilepsy are more likely to have combined type (76.4%) and learning disability as compared with ADHD without epilepsy.

We report a case of neuroblastoma with multiple skin metastases as a chief complaint in a 2-month-old girl. the skin lesions were rnultiple, pea-sized, bluish, nontender, moable subcutaneous nodules on abdomen, back and scalp. Histopathology showed small round or poly gonal tumor cells which have deeply stained, basophilic, hyperchromatic nuclei with some mitoses. Th.se tumor cells showed clumping tendency which is one of early menifestations of rosette formation. Immunohistochemically positive reaction was demonstrated by anti-NSE(neuron specific enolase) antilody but negative reaction by anti-NFP (neurofilament proteiin ) antibody. She has been succesfully treated with combined chemotherapy for 10 months without relapse.

Nimodipine the potent, centrally active, clacium channel blocker, is known to increase cerebral and spinal blood flow. In the present study, the authors investigated the effect on Nimodipine on injured spinal cord. The experiment was a randomized blind study in which four groups of five cats received Nimodipine(0.05mg/kg) intravenously, and control groups of five cats received only Diluent. As a step in the investigation of the possible effect of spinal cord trauma on biochemical and ultrastructural changes in the injured cord, activities of lipid peroxidation were measured in the frozened-dried sample of the spinal cord and fine structure of the mylinated nerve fiber in the white matter were observed. An increase of lipid peroxidation level was found as early as 1 hour after the injury and the highest concentration was reached at 5 hours after the injury(P<0.01). Fine structures of the myelinated nerve fibers were changed progressively with the lapse of time after the injury. The effect of Nimodipine on lipid peroxidation and fine ultrastructural changes of myelinated nerve fibers were studied, and the result of this study revealed that Nimodipine groups showed a lower level of lipid peroxidation with statistical significance(P<0.05) and preservation of ultrastructural myelinated nerve fiber was prominent.

PURPOSE: To assess the usefulness of amplitude integrated electroencephalography (aEEG), we compared aEEG with electroencephalography (EEG), which is one of the most useful tools for assessment of neonatal seizures in the neonatal intensive care unit. METHODS: We retrospectively studied 24 neonates who had been suspected of seizure activity in the neonatal intensive care unit from January 2009 to February 2010. The 24 neonates had seizure or apnea that did not respond to aminophylline or continuous positive airway pressure. We compared the correlation and efficacy of diagnosis among aEEG, EEG, and neurosonography. RESULTS: We analyzed 24 aEEGs in the neonatal intensive care unit. The aEEGs showed a seizure pattern in 15 (62.6%), burst suppression pattern in 2 (8.3%), flat pattern in 4 (8.3%), and normal in 5 (20.8%). The results of EEGs showed 15 neonatal seizures (62.5%), 2 cerebral dysfunctions (8.3%), and 7 normal findings (29.2%). A correlation between aEEG and EEG was noted (P<0.05). However, there was no correlation between the results of aEEG and echoencephalography. CONCLUSION: There is correlation between aEEG and EEG for seizure detection in the neonatal intensive care unit. We think that aEEG is an useful screening tool for seizure detection in neonates.

PURPOSE: Retrospective study was performed to evaluate the survivals, remission rate and complications of induction chemotherapy using N(4)-behenoyl-1-beta-D-arabinofuranosylcytosine (BH-AC), idarubicin and 6-thioguanine (6-TG) in newly diagnosed childhood acute myelogenous leukemia. METHODS: From July 1994 to March 2000, 40 children (male 30, female 10) were enrolled in the study. From day 0 to 6 of induction, BH-AC 300 mg/m(2)/day was administered intravenously over 3 hours and from day 7 to 9, dosage was adjusted according to residual leukemic blasts in day 7 bone marrow aspirates. Idarubicin 10 mg/m(2)/day was administered intravenously over 15 minutes from day 0 to 2 and 6-TG 100 mg/m(2)/ day orally divided in two from day 0 to 6. Median age at diagnosis was 4.4 years (1 month~14.9 years) with a distribution according to the FAB classification of 1 M1, 10 M2, 13 M4, 5 M4E, 7 M5a, 3 M6 and 1 M7. RESULTS: Complete remission (CR) rate was 82.5% (33/40) with one cycle of induction chemotherapy and 90.0% (36/40) with additional cycle (BH-AC and idarubicin). One patient achieved partial remission with one cycle and was lost to follow-up, and 3 died of septic shock with disseminated intravascular coagulopathy during induction. Median time to CR from diagnosis was 28 days (25~68) and recovery from neutropenia (ANC> 1,000/muL) was achieved on median day 24 (21~44). All 40 patients had a fever during neutropenic period. Toxicities such as diarrhea, mucositis, nausea and vomiting were observed over half of the patients but tolerable and transient. Five-year overall, relapse- free and event-free survivals were 54.0%, 51.1% and 46.7%, respectively. CONCLUSION: These data show that this regimen is superior to others with high remission rate and well tolerated.

Gestational trophoblastic disease comprises a spectrum of interrelated conditions originating from the placenta. Malignant gestational trophoblastic disease refers to lesions that have the potential for local invasion and metastasis. This compromises many histological entities including hydatidiform moles, invasive moles, gestational choriocarcinomas, and placental site trophoblastic tumors. Before the advent of sensitive assays for human chorionic gonadotropin (hCG) and efficacious chemotherapy, the morbidity and mortality from gestational trophoblastic disease were substantial. Currently, with sensitive quantitative assays for beta-hCG and current approaches to chemotherapy, most women with malignant trophoblastic disease can be cured. We present a case of malignant gestational trophobalstic tumor with serum beta-hCG concentration over 1million IU/L that metastaze to the lungs and have a hyperthyroidism, but negative urine hCG testing. We report a case with a brief review of literatures.

Cronkhite-Cadana syndrome is a rare non-familial disease. This syndrome is characterized by multiple hamartomatous polyps on the entire gastrointestinal tract except esophagus, nail dystrophy, alopecia and hyperpigmentation. Taste disturbance, abdominal pain, diarrhea and weight loss are common symptoms of it. The pathogenesis and causes of Cronkhite-Canada syndrome remain unknown until now. Although various treatment strategies including steroid therapy have been tried, their prognosis is poor. We report a 68 years old man who were diagnosed Cronkhite-Canada syndrome with esophageal candidiasis. After using combination of steroids and anti-fungal drugs, both Cronkhite-Canada syndrome and esophageal candidiasis were cured.

PURPOSE: This study aimed to evaluate the effects of fibronectin and oxysterol immobilized on machined-surface dental implants for the enhancement of cell attachment and osteogenic differentiation, on peri-implant bone healing in the early healing phase using an experimental model in dogs. METHODS: Five types of dental implants were installed at a healed alveolar ridge in five dogs: a machined-surface implant (MI), apatite-coated MI (AMI), fibronectin-loaded AMI (FAMI), oxysterol-loaded AMI (OAMI), and sand-blasted, large-grit, acid-etched surface implant (SLAI). A randomly selected unilateral ridge was observed for 2 weeks, and the contralateral ridge for a 4-week period. Histologic and histometric analyses were performed for the bone-to-implant contact proportion (BIC) and bone density around the dental implant surface. RESULTS: Different bone healing patterns were observed according to the type of implant surface 2 weeks after installation; newly formed bone continuously lined the entire surfaces in specimens of the FAMI and SLAI groups, whereas bony trabecula from adjacent bone tissue appeared with minimal new bone lining onto the surface in the MI, AMI, and OAMI groups. Histometric results revealed a significant reduction in the BIC in MI, AMI, and OAMI compared to SLAI, but FAMI demonstrated a comparable BIC with SLAI. Although both the BIC and bone density increased from a 2- to 4-week healing period, bone density showed no significant difference among any of the experimental and control groups. CONCLUSIONS: A fibronectin-coated implant surface designed for cell adhesion could increase contact osteogenesis in the early bone healing phase, but an oxysterol-coated implant surface designed for osteoinductivity could not modify early bone healing around implants in normal bone physiology.

A few cases of severe pulmonary hypertension with right heart failure associated with Graves' disease were reported in the literature. However, cases of pulmonary hypertension with right heart failure recurred by Graves' disease is very rare. We describe the case of a 60-year old woman who had been treated pulmonary hypertension caused by right pulmonary artery thromboembolism seven years ago. Recently, her pulmonary hypertension with right heart failure was recurred by Graves' disease. The patient's symptoms of pulmonary hypertension was resolved after treatment of Graves' disease.

In recent years, improved antibiotic care and physiologic fluid replacement in cases involving burn wounds have led to a decrease in the rate of fatalaties caused by wound sepsis and shock. There has, however, been an upsurge and relative increase in the frequency (15 -25%) and mortality rate (50 -89 %) of pulmonary complications. Since pulmonary lesions may result from direct injury to the respiratory tract caused by smoke inhalation, from circulatory, metabolic or infectious complications in cases involving cutaneous burns, or may develop during the therapeutic management of these lesions, a wide spectrum of pulmonary abnormalities can occur during the post-burn period. There is considerable overlap between their radiographic appearances, which are often nonspecific. Since the successful management of these patients is based on the early recognition and vig-orous treatment of lesions, familiarity with all facets of these complications, based on a pathophysiology of the injury and on the knowledge of the clinical setting, enables radiologists to make more specific diagnoses.
