Ki Woong Sung
Clin Exp Pediatr. 2012;55(4):115-120.   Published online April 30, 2012

Although high-dose chemotherapy and autologous stem cell transplantation (HDCT/autoSCT) have improved the prognosis for patients with high-risk neuroblastoma (NB), event-free survival rates remain in the range of 30 to 40%, which is unsatisfactory. To further improve outcomes, several clinical trials, including tandem HDCT/autoSCT, high-dose 131I-metaiodobenzylguanidine treatment, and immunotherapy with NB specific antibody, have been undertaken and pilot studies have reported...

Responses and adverse effects of carboplatin-based chemotherapy for pediatric intracranial germ cell tumors
Suntae Ji, Hee Won Chueh, Ju Youn Kim, Su Jin Lim, Eun Joo Cho, Soo Hyun Lee, Keon Hee Yoo, Ki Woong Sung, Hong Hoe Koo
Clin Exp Pediatr. 2011;54(3):128-132.   Published online March 31, 2011
Purpose

Cisplatin-based chemotherapy has been commonly used for the treatment of intracranial germ cell tumors (IC-GCTs). However, this treatment exhibits some adverse effects such as renal problems and hearing difficulty. Carboplatin-based chemotherapy was administered to pediatric patients with IC-GCTs from August 2004 at the Samsung Medical Center. In this study, we assessed the responses and adverse effects of carboplatin-based chemotherapy in...

Clin Exp Pediatr. 2010;53(6):701-704.   Published online June 23, 2010
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.
