Prognostic factors and treatment of pediatric acute lymphoblastic leukemia
Jae Wook Lee, Bin Cho
Clin Exp Pediatr. 2017;60(5):129-137.   Published online May 31, 2017

The event-free survival (EFS) for pediatric acute lymphoblastic leukemia (ALL) has shown remarkable improvement in the past several decades. In Korea also, a recent study showed 10-year EFS of 78.5%. Much of the improved outcome for pediatric ALL stems from the accurate identification of prognostic factors, the designation of risk group based on these factors, and treatment of appropriate duration...

Systemic use of fluoroquinolone in children
Soo-Han Choi, Eun Young Kim, Yae-Jean Kim
Clin Exp Pediatr. 2013;56(5):196-201.   Published online May 28, 2013

Fluoroquinolones are an important class of antibiotics that are widely used in adult patients because of their broad spectrum of activity, good tissue penetration, and oral bioavailability. However, fluoroquinolone use in children is limited because juvenile animals developed arthropathy in previous experiments on fluoroquinolone use. Indications for fluoroquinolone use in patients younger than 18 years, as stated by the U.S....
