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.

Korean Journal of Medical Education 2007;19(4):271-278
PURPOSE: The present study examined the possibility of standardization of medical education in three Asian countries-Korea, China, and Japan, by comparing their medical education and licensing systems. METHODS: As the criterion for comparison, we divided medical education system into three stages- basic medical education, graduate medical education, and continuing medical education. In addition, we analyzed the history and social and cultural backgrounds of medical education in each country. Recent changes were also examined. RESULTS: While little difference was found in the medical curriculums and courses between Korea and Japan, China's differed significantly from these two countries. But all three countries do attempt to keep up with international standards. CONCLUSION: To improve the quality of medical education in Korea, China, and Japan, these three countries need a plan to standardize medical education compatible with international standards but one that differs from western medical education by incorporating traditional medicine.

The purpose of this study is to compare the physical health, anxiety and depression of the Dan-Jeon Breathing trained group with those of a non-trained group and to analyze the relationship between the training period of Dan-Jeon Bre athing method and physical health, anxiety, and depression. The number of people in the Dan-Jeon Breathing trained group over 3 months was 149 and in the non-trained group 142. Data were collected from August to October 1999. As tools, 35 physical symptom questions were chosen from The Cornell Medical Index modified by Nam(1965) and from the Symptom Checklist-90-Revision(SCL-90-R) by Kim(1984); 10 questions on anxiety and 13 questions on depression were used in the study. The statistics of the study were gathered by using SPSS Window; the analysis was made by applying x(2)-test, t-test, Pearson correlation, ANOVA and Scheffe tests. The results were as follows. 1. The Dan-Jeon Breathing trained group had lower physical symptom score and showed less anxiety and depression than the non-trained group, which supported the 1st, 2nd, 3rd hypotheses. 2. The longer the training period of Dan-Jeon Breathing, the lower the physical symptom score, which supports the 4th hypothesis, but the 5th and, 6th hypotheses were not supported because anxiety and depression did not get lower as the training period of Dan-Jeon Breathing got longer. 3. The physical symptom score, anxiety and depression that were made by the general characteristics of Dan-Jeon Breathing trained group were analyzed. As a result, the physical symptom score of women was greater than that of men. Physical symptoms score and the rate of anxiety and depression were different by education levels. The degree of anxiety was different by age. Those who have a religion have a higher physical symtoms score than people who have no religion. There was no difference in physical health score, anxiety and depression according to marital status, economic status and occupations. The results suggest that the physical and mental health status of Dan-Jeon Breathing trained group is better than that of the non-trained group. Physical symptoms scores gets lower as the training period of Dan-Jeon Breathing gets longer which results in the improvement of physical health status.

A total of 4757 apparently healthy aged persons over 65 years of age was surveyed for geriatric hypertension. A single blood pressure measurement was taken in the sitting position. Mean systolic blood pressure rose significantly with age in female but didn't in male and mean diastolic blood pressure didn't change with age in both sex. The prevalence of pure systolic hypertension, i.e., a systolic blood pressure greater than or equal to 160 mmhg and a diastolic blood pressure less than 95mmhg, increased with age. The prevalence was slighty lower for female than it was for male, being 7.0% for female and 8.0% for male. The prevalence of classical hypertension-defined as diastolic blood pressure greater than or equal to 95mmhg - was 42.7% for female and 48.2% for male and it rose with age in female. The prevalence of both pure systolic and classical hypertension was 49.7% for female and 56.1% for male.

Mullerian agenesis or dysgenesis, rare developmental anomaly presenting as primary amenorrhea, is characterized by absence of vagina and absence or rudimentary development of the uterus. Anatomic anomalies of the axial skeleton and kindney often accompany this psychologically devatating condition. There are various methods of surgical treatment for congenital absence of the vagina. The six cases reviewed in this paper were all treated with McIndoe technique. All of 6 women experienced satisfactory sexual activity and were satisfied with vaginal depth following vaginal creation using a split thickness skin graft technique. Despite the existence of several alternative methods, the McIndoe technique is a relatively simple and highly successful procedure and hence is still prefered by many surgeons.

BACKGROUND: The pathogenesis of confluent and reticulated papillomatosis(CRP) is still unknown, although many theories have been suggested. It is stressed that abnormal host response to colonization of pityrosporum orbiculare might play a role in the pathogenesis of CRP, but is not completely understood. Frequently, we have observed bacterial colonies in the stratum corneum and, especially, within the hair follicles from biopsy specimens of patients with CRP. In addition, successful treatment for CRP with minocycline, a derivative of tetracyclines, has been reported continuously. OBJECTIVE: The purpose of this study was to document the possible association of bacterial factors in the pathogenesis of CRP and to elucidate the effectiveness of minocycline. METHODS: We performed Brown and Brenn gram staining in 12 biopsy specimens, bacterial cultures, identification of microorganisms and antibiotics sensitivity testing including minocycline. We administered oral minocycline with an initial dose of 100mg per day for 1 to 3 months and a maintenance dose 50mg per day for I to 2 months, then evaluated the response of treatment. RESULTS: 1. On Brown and Brenn staining, the gram positive bacterial colonies that stained dark bluish or nearly black were observed within the infundibulum of hair follicles in 10 out of 12 biopsy specimens(83.3%) and on the keratotic invagination of stratum corneum in 11 out of 12 biopsy specimens(91.7%). 2. Histological features of regions where bacterial colonies were observed showed, hyperkeratosis and keratotic invagination on the stratum corneum in all cases. Hyperkeratosis(66.7%), parakeratosis(16.7%), inflammatory cell infiltration(25.0%), perifollicular fibrosis(33.3%), and abnormal keratin in sebaceous ducts(50.0%) were shown in hair follicles. 3. In anaerobic cultures, no bacteria was grown. In aerobic cultures, staphylococcus species were identified in 6 cases, streptococcus viridans in one case, sternotrophomonas maltophilia in one case. In the susceptibiliity test, minocycline was sensitive in 7 from 8 cases. 4. The therapeutic response to minocycline was observed within one month in all cases, and the time to clear the lesions was 1/2 month in 2 cases, 1 month in 4 cases, 2 months in 5 cases, 3 months in one case, respectively. CONCLUSION: Form these results, we suggest that bacterial factors may play an important role in the pathogenesis of CRP and that the action mechanism of minocycline in the treatment of CRP may be due to antibacterial effects.

Idiopathic CD4+ T lymphocytopenia (ICL) is a new disease entity characterized by depletion of helper T cells apparently without any evidence of HIV infection. We report a case of ICL associated with Kaposis sarcoma (KS) and pneumocystis carinii pneumonia (PCP) in a 34-year old woman. She developed violaceous, protruding masses on scalp, back, both extremities, palms, soles, left. first toe and peritonsillar region for 2 months. These lesions were confirmed as KS by histopathologic findings. Chest X-ray and HRCT findings represented PCP and KS. Absolute deficiency of CD4+ T cell was detected in the count of T cell subsets. Serologic tests for HIV-1, 2 and HTLV I, -II were negative. And she was absent any defined immunodeficiency or therapy associated with decreased levels of CD4+ T cells. By CDC criteria, a diagnosis of ICL was made. Because of aggravation of PCP and lung involuement of KS, she died at 22nd day after admission.
