Clin Exp Pediatr. 2014;57(6):278-286.   Published online June 30, 2014
Purpose

To evaluate the potential utility of 123I-metaiodobenzylguanine (123I-MIBG) scintigraphy and 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) for the detection of primary and metastatic lesions in pediatric neuroblastoma (NBL) patients, and to determine whether 18F-FDG PET is as beneficial as 123I-MIBG imaging.

Methods

We selected 8 NBL patients with significant residual mass after operation and who had paired 123I-MIBG and 18F-FDG PET images...

Recent advances in the diagnosis and management of childhood acute promyelocytic leukemia
Eun Sun Yoo
Clin Exp Pediatr. 2011;54(3):95-105.   Published online March 31, 2011

Since the successful introduction of all-trans-retinoic acid (ATRA) and its combination with anthracycline-containing chemotherapy, the prognosis for acute promyelocytic leukemia (APL) has markedly improved. With ATRA and anthracycline-based-chemotherapy, the complete remission rate is greater than 90%, and the long-term survival rate is 70-89%. Moreover, arsenic trioxide (ATO), which was introduced for APL treatment in 1994, resulted in excellent remission rates...

Neutropenia in children
Eun Sun Yoo
Clin Exp Pediatr. 2009;52(6):633-643.   Published online June 15, 2009
Neutropenia is defined as an absolute neutrophil count (ANC) of ＜1,500/µL, and the severity of neutropenia generally can be graded as mild (1,000-1,500/µL), moderate (500-1,000/µL), or severe (＜500/µL). This stratification aids in predicting the risk of pyogenic infection because the susceptibility to life-threatening infections is significantly increased in patients with prolonged episodes of severe neutropenia. Especially cancer-related neutropenia carry significant...

Clin Exp Pediatr. 2000;43(2):288-293.   Published online February 15, 2000
Hepatoblastoma is the most common primary malignant liver tumor in childhood. Most cases are boys generally below three years of age. Hepatoblastoma are associated with various non-metastatic syndromes. Rarely, human chorionic gonadotropin may be produced by the tumor. Ectopic gonadotropin production from this source is a rare cause of precocious puberty in boys. Since a report by Behrendt in 1931,...
