PURPOSE: Cerebral palsy or hearing disability of hyperbilirubinemic complication was reduced by blood exchange transfusion(BET) and phototherapy(PT). But in spite of these treatment, abnormal Auditory Brainstem evoked Response(ABR) finding after BET or PT and neurodevelopmental defect due to chronic bilirubin encephalopathy were observed. So we have studied risk factors and outcome of chronic bilirubin encephalopathy after BET, and treatment of hyperbilirubinemia. METHODS: We have analyzed clinical characteristics, the finding and change of ABR after BET in 17 hyperbilirubinemic neonates, and in 8 hyperbilirubinemic neonates who were treated by phototherapy and 15 normal control neonates. RESULTS: 1) Mean bilirubin concentraion were 27.5+/-4.1mg/dL in BET group and 22.1+/-2.3 mg/dL in PT group. There were no difference of clinical findings between BET and PT group. 2) Change of ABR (1) Wave I loss resulted in 4 neonates, wave III loss in 3 neonates, and wave V loss in 2 neonates in BET group(P<0.05). (2) Wave I peak latency and hearing threshold in BET group were significantly increased more than normal control group(P<0.01). 3) In 10 neonates(58.8%) among 17 BET group, 4 neonates(50%) in 8 PT group were observed abnormal initial ABR finding after jaundice treatment. Age at treatment and duration of jaundice(interval between onset of jaundice and treatment) in abnormal ABR group were significant prolongation compared with normal ABR group(P<0.05). 4) Chronic bilirubin encephalopathy(CBE) was observed in 3 neonates(17.6%) among 17 BET group and showed higher of bilirubin level than normalized group after BET (31.1mg/dL vs 26.6mg/dL), other clinical findings showed no significant differences. CONCLUSION: Bilirubin level was significantly elevated in CBE more than in BET group and duration of jaundice, age at treatment were longer in abnormal ABR group than in normal ABR group. So not only bilirubin level but also duration of jaundice shoud be considered at jaundice treatment, and ABR has a potential utility in detection of acute brain toxicity of bilirubin and follow up evaluation of bilirubin encephalopathy.

3.Analysis of the Contributions of Original Articles in Major Dermatology Journals in Korea.
Korean Journal of Dermatology 2007;45(5):439-444
BACKGROUND: The Korean Journal of Dermatology and the Annals of Dermatology are representative journals of dermatology in Korea. Evaluation of their content, authors and affiliations are valuable for our understanding of the situation, trends and interests of the Korean dermatologic society. OBJECTIVE: To analyze the original contributions in the major dermatology journals of Korea, and compare these with those of renowned international dermatology journals in terms of original contribution. METHODS: A total of 318 original articles from the last 3 volumes of the Korean Journal of Dermatology (2003, vol. 41 to 2005, vol. 43) were collected and analyzed for their characteristic features, such as categories, authors, and affiliations. We also compared these characteristic features with those of 18 original articles from the last 3 volumes of Annals of Dermatology (2003, vol. 15 to 2005, vol. 17), an English dermatologic journal in Korea. RESULTS: Thirty-two percent of original articles fell into the category of drug evaluation and clinical research, followed by laboratory and experimental research. Most articles had three to six co-authors (78%), and one (55.3%) or two (31.1%) affiliations. The number of articles by a specific corresponding author ranged from one to eight, and the majority of articles by a specific corresponding author were one (43.6%) during 3 years. These situations were similar with those of the Annals of Dermatology. The evaluation of the Korean Journal of Dermatology about charateristics of original articles showed a small number of original articles by a corresponding author and cooperative researches with other afilliations. The main subjects of articles were centralized to 3 major categories in the Korean Journal of Dermatology, whereas the other famous international journals showed a relatively uniform distribution. CONCLUSION: The participation of non-dermatologists was fewer in the Korean journals than the other famous international journals. The Korean dermatologic society should make an effort to involve the specialists of other fields in submitting excellent original articles to the Korean Journal of Dermatology. And for the academic position of the Korean dermatologic society, we should make an effort to register one of our journals to the SCI (science citation index). The Korean Journal of Dermatology should deal with more varied articles from new categories for a more uniform distribution of themes. It should also make more effort to improve the Korean Journal of Dermatology.

BACKGROUND: Using c-fos expression one of the immediate early gene, as a marker of altered neuronal response, we investigated the effect of superior cervical ganglion block (SCGB) exhibiting the same effect of SGB of human on the activity of several brain regions which are considered as located on autonomic neural pathway and neuroendocrine axis in rat. METHOD: The 48 Sprague-Dawley strain rats were divided into 4 groups, as saline/stress (control) group, SCGB/stress (tested) group, saline group, SCGB group. Superior cervical ganglion block was conducted in the SCGB/stress group and SCGB group while saline/stress and saline group were sham operated. After then restraint stress was imposed on the animals of SCGB/stress group and saline/stress group. And 2 hour after injection (saline, SCGB group) or restraint stress (saline/stress, SCGB/stress group), c-fos protein (Fos) was localized by immunocytochemistry. RESULTS: Much stronger Fos immunoreactivity was induced in the several brain region of control group rats compared to other three groups and the numbers of Fos positive cell count of tested group were significantly decreased in paraventricular hypothalamic nucleus (p<0.01), A5 (p<0.01), raphe pallidus (p<0.05), nucleus tractus solitaius (p<0.01) compared to control group. CONCLUSION: This study demonstrate that superior cervical ganglion block attenuates stress induced neuronal activities of paraventricular hypothalamic nucleus, A5, raphe pallidus, nucleus tractus solitarius.

Primary ampullary carcinoma is one of rare gastrointestinal malignancies which can be diagnosed by ERCP and endoscopic biopsy. However, sometimes it is difficult to comfirm the diagnosis when the tumor is not exposed out of orifice of ampulla. Recently, we diagnosed early stage ampullary carcinoma using endoscopic sphincetrotomy for the exposure of tumor in 54 year old woman ia whom ERCP revealed rather impacted stone like filling defect in distal common bile duct. we describe a case of papillary adenocarcinoma of the ampulla of Vater diagnosed by edoscopic sphincterotomy.

8.Life Persistence of Attention-Deficit/Hyperactivity Disorder.
Hanyang Medical Reviews 2016;36(1):38-45
This paper is to review Attention Deficit-Hyperactivity Disorder (ADHD) in the developmental perspective, focusing on clinical features, diagnosis and treatment of ADHD throughout life stage. When diagnosed with ADHD, before entering elementary school early diagnosis and early intervention is encouraged to reduce various impairments that occur during development. Thirty to eighty percent of school-age ADHD symptoms remain throughout the adolescence or meet the ADHD diagnosis criteria. During adolescence, hyperactivity and impulsiveness from other existing symptoms become less severe but children have insufficiency to continue studying or task compared to their peers. Pharmacologic treatment had been shown to be the most effective treatment regimen for adolescents who continue to have ADHD symptoms. In adults, representative symptoms of ADHD, hyperactivity and impulsiveness, often gradually decrease while lack of concentration remains. As Conner's Adult ADHD Diagnostic Interview for DSM-IV (CAADID), a structured interview for the diagnosis of adulthood ADHD has been translated into Korean, it can be applied clinically. Pharmacological and nonpharmacological treatment in adults had been shown to be effective.

PURPOSE: Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder with widespread manifestations that rarely include the eye. We present a case of SLE-associated choroidoretinopathy and secondary angle closure attack in both eyes. CASE SUMMARY: A 58-year-old male was admitted into the urologic department complaining of right scrotal swelling, and then consulted with the ophthalmology department regarding both ocular pain and eye injection. The patient was diagnosed with acute angle closure attack using a slit lamp test and tonometry secondary to choroidoretinitis with choroidal detachment at fundus examination in both eyes. The rheumatologist performed systemic evaluation, including serologic tests, and then diagnosed the patient with SLE. After systemic steroid therapy, intraocular pressure was decreased and choroidal detachment disappeared with improvements of choroidoretinitis in both eyes. CONCLUSIONS: Patients with systemic lupus erythematosus choroidopathy can develop secondary angle closure attack, which can be effectively treated using systemic steroid therapy and antiglaucoma drugs.

This experiment was focused on the characterization of anti-Toxoplasma monoclonal antibodies (mAbs) and the effect of mAbs on the parasite invasion of mouse peritoneal macrophages. Twenty eight mAbs including M110, M556, R7A6 and M621 were characterized by Ab titer, immunoglobulin isotyping and western blot pattern. Antibody titer (optical density) of 4 mAbs, M110, M556, R7A6 and M621, were 0.53, 0.67, 0.45 and 0.39 (normal mouse serum; 0.19) with the same IgG1 isotypes shown by Enzyme-linked immunosorbent assay (ELISA). Western blot analysis showed that M110, M556, R7A6 and M621 reacted with the 33 kDa (p30), 31 kDa (p28), 43 kDa and 36 kDa protein. Immunogold labelling of mAbs M110, M556, R7A6 and M621 reacted with the surface membrane, dense granules and parasitophorous vacuolar membrane (PVM), rhoptries and cytoplasm of tachyzoite, respectively. For in vitro assay, preincubation of tachyzoites with four mAbs, M110, M556, R7A6 and M621 resulted in the decrease of the number of infected macrophages (P < 0.05) and the suppression of parasite multiplication at 18 h post-infection. Four monoclonal antibodies including M110 (SAG1) were found to have an important role in the inhibition of macrophage invasion and T. gondii multiplication in vitro, and these mAbs may be suitable for vaccine candidates, diagnostic kit and for chemotherapy.
