Yoon Young Jang, Hye Jin Park
Clin Exp Pediatr. 2009;52(10):1175-1180.   Published online October 15, 2009
We report a case of a full-term neonate with persistent pulmonary hypertension who developed asphyxia after birth and was treated with iloprost. The neonate had persistent hypoxia and did not respond to supportive treatment. Because inhaled nitric oxide (iNO) was not available in our hospital, inhaled iloprost was administered via an endotracheal tube. This resulted in an immediate elevation of...

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...
