Neuroprotective effects of erythropoietin against hypoxic injury via modulation of the mitogen-activated protein kinase pathway and apoptosis
Ji Eun Jeong, Jae Hyun Park, Chun Soo Kim, Sang Lak Lee, Hai Lee Chung, Woo Taek Kim, Eun Joo Lee
Clin Exp Pediatr. 2017;60(6):181-188.   Published online June 22, 2017
Purpose

Hypoxic-ischemic encephalopathy is a significant cause of neonatal morbidity and mortality. Erythropoietin (EPO) is emerging as a therapeutic candidate for neuroprotection. Therefore, this study was designed to determine the neuroprotective role of recombinant human EPO (rHuEPO) and the possible mechanisms by which mitogen-activated protein kinase (MAPK) signaling pathway including extracellular signal-regulated kinase (ERK1/2), JNK, and p38 MAPK is modulated in...

Clin Exp Pediatr. 2009;52(1):129-132.   Published online January 15, 2009
We describe here our experience with a neonate presenting with cyanosis, grunting, and cardiomegaly, who was diagnosed with isolated left ventricular noncompaction (IVNC) by echocardiography. The patient had high levels of N-terminal pro-B-type natriuretic peptide (NT pro-BNP) and symptoms of heart failure including poor feeding and tachypnea. During the period in which NT pro-BNP levels steadily increased, the patient suffered...

Primary tumors of the heart are uncommon among pediatric patients. Rhabdomyoma is the most frequent cardiac tumor in infants and children, which is commonly associated with tuberous sclerosis. Tuberous sclerosis is a neurocutaneous syndrome affecting the brain, heart, skin, and other organs. Cardiac rhadomyomas are reported in 50-64% of infants with tuberous sclerosis. Tuberous sclerosis involves multiple locations in the...

Clin Exp Pediatr. 2006;49(1):6-13.   Published online January 15, 2006
Jaundice is one of the most common gastrointestinal conditions found in neonatal period, and most jaundice is benign. But because of the possibility of bilirubin toxicity, every newborn infants must be examined to identify the development of severe hyperbilirubinemia. To prevent the development of severe hyperbilirubinemia, promote and support successful breast-feeding, perform a systemic assessment before discharge for the risk...

Jun Chul Byun, Chun Soo Kim, Sang Lak Lee, Tae Chan Kwon, Hee Jung Lee
Clin Exp Pediatr. 2004;47(11):1216-1219.   Published online November 15, 2004
Weaver syndrome is a very rare overgrowth syndrome with accelerated skeletal maturation, unusual facies and clinodactyly. We experienced an extremely rare case of Weaver syndrome in Korea. The clinical manifestations were macrocephaly, unusal facies, simian crease, clinodactyly, decreased muscle tone, accelerated bone age and congenital heart diseases. We report this with a brief review of related literature.

Clin Exp Pediatr. 2003;46(8):784-788.   Published online August 15, 2003
Purpose : Perinatal asphyxia occurring in newborn is one of the major causes of acute mortality and chronic neurological disability in survivors. We have studied the relationship between early electroencephalography(EEG) findings and clinical course and neurologic outcome in severe asphyxiated neonates. Methods : Between the period of July 1999 and June 2002, 25 neonates who were diagnosed with severe perinatal asphyxia(1-minute...

Cytomegalovirus(CMV) is one of the leading cause of intrauterine infections of man with an incidence ranging from 0.48% to 2.2% of all live births. Although the majority of CMV-infected newborns are clinically asymptomatic at birth, some will have signs of congenital infection : Intrauterine growth retardation, petechial or purpuric rash, microcephaly, anemia, thrombocytopenia, jaundice, hepatosplenomegaly and intracranial calcification. We experienced...
