Eosinophil disorders
Sun Young Kim
Clin Exp Pediatr. 2009;52(6):643-648.   Published online June 15, 2009
Blood eosinophilia can be classified as either familial or acquired. Familial eosinophilia is a rare autosomal dominant disorder characterized by a stable eosinophil count. Acquired eosinophilia is classified further into a primary or secondary phenomenon depending on whether eosinophils are considered integral to the underlying disease. Primary eosinophilia is considered clonal in the presence of either a cytogenetic abnormality or...

Effect of intravenous deferoxamine in multiply transfused patients
Sang Min Oh, Joon Won Kang, Sun Young Kim
Clin Exp Pediatr. 2007;50(12):1225-1230.   Published online December 15, 2007
Purpose : Multiple transfusions in patients with chronic anemia can result in excessive iron deposition in tissues and organs. Effective iron chelation therapy in chronically transfused patients can only be achieved when iron chelators remove sufficient amounts of iron equivalent to those accumulated in the body from transfusions, thus leading to maintain body iron load at a non-toxic level. This...
