Choi, Sei-Woong,Mironov, Vladimir,Kim, Sung-Soo The Korean Society of Systematic Zoology 2011 Korean Journal of Systematic Zoology Special Issue Vol.27 No.1
In this paper, we report for the first time on a species of Eupithecia from Korea. Three females of Eupithecia praepupillata Wehrli, 1927, were collected from the northeastern part of South Korea. With this addition, a total of 53 species of Eupithecia from Korea have been recorded. Diagnosis and description of the species are provided with figures of the genitalia.

Purpose: Dengue fever occurs in many popular tourist destinations and is increasingly imported by returning travelers in Korea. Since Korea is not an endemic country for dengue fever, pediatricians do not usually suspect dengue fever in febrile children even with typical presentation and exposure history. This study was performed to describe the international travel experiences and dengue fever in Korean children. Methods: Travel histories were collected based on questionnaires completed by all patients' guardians who visited the pediatric infectious diseases clinic at Samsung Medical Center from January 2008 to December 2008. For patients who were suspected of dengue fever, a serological test was performed. Results: Five hundred and seventeen children visited the pediatric infectious diseases clinic for the first time during this period. About 30% of patients who responded to the questionnaire (101/339) had experienced international travel within the last 2 years. Four patients were diagnosed with dengue fever by serological test. Conclusion: Increasing numbers of Korean children visit dengue endemic areas and they may return home with dengue fever. Dengue fever should be suspected in patients who have a travel history to endemic areas.

Purpose: Pediatric liver transplantation (PLT) has been the key therapy for end stage liver disease and the outcome has been excellent. However, still surgical complication associated with small recipient is the main cause of graft loss. In the present study, we assessed recent advances in outcome of PLTs through our experience. Methods: A total of 235 PLTs performed between Mar 1988 and July 2015 were analyzed. Three chronological periods were investigated: the initial period (1988-2007, n=117), the mid-term period in which our PLT management protocol was settled down (2008-2011, n=62), and the period in which surgical procedures were refined for small children (2012-2015, n=56). Results: The grafts’ (84% vs. 82% vs. 98%) and patients’ (84% vs. 87% vs. 98%) survival have been improved (p<0.05), whereas the number of biliary atresia (31% vs. 45% vs. 50%) deceased and the proportion of deceased donor (24% vs. 36% vs. 52%) and split PLT (7%vs. 16% vs. 46%) increased (p<0.05). The number of re-LT (3% vs. 9% vs. 2%) has been changed. ABO incompatible PLT has introduced on the last period (9%). Conclusion: The quality of the PLT has recently been standardized through a large volume of experience, and the operation has been proven to improve the survival outcome. However, a constant evaluation of our experience is critical for further progress.

Background: Various treatment modalities for atrophic acne scars have been used. CROSS technique (Chemical Reconstruction of Skin Scars), using 100% TCA, has the advantage of reconstructing acne scars by focusing on the dermal thickening and collagen production. But, phenol CROSS technique is not widely used for acne scars in Asian. To this data, there are no prospectively comparative studies between TCA CROSS and phenol CROSS. Objectives: The purpose of this study was to evaluate the clinical effectiveness and safety of 100% TCA CROSS and phenol CROSS in the facial atrophic acne scars. Methods: 24 participants were randomly equally divided into two groups; group 1 underwent two sessions (8 week apart) of 100% TCA CROSS, and group 2 underwent two sessions (8 weeks apart) of phenol CROSS. Results: There has been 24 patients that completed the study. At the 0, 8, 20 week visits, both groups showed an acceptable improvement in all nearly parameter. However, in comparison between the groups, there was no statistically differences (p >0.05). The difference in the degree of improvement was not statistically significant between the groups. Mild complications were seen in both treatment groups. There is no severe side effect on both groups. Conclusion: Both 100% TCA CROSS and phenol CROSS are effective treatment modalities for atrophic acne scars. However, the results of the present study suggest that 100% TCA CROSS might lead to more good improvements according to the patients satisfaction.
