Clin Exp Pediatr. 2013;56(3):139-142.   Published online March 18, 2013

X-linked recessive myotubular myopathy (XLMTM) is a severe congenital muscle disorder caused by mutations in the MTM1 gene and characterized by severe hypotonia and generalized muscle weakness in affected males. It is generally a fatal disorder during the neonatal period and early infancy. The diagnosis is based on typical histopathological findings on muscle biopsy, combined with suggestive clinical features. We...

Magnetic resonance imaging and spectroscopic analysis in 5 cases of Pelizaeus-Merzbacher disease: metabolic abnormalities as diagnostic tools
Eun Lee, Mi-Sun Yum, Hae-Won Choi, Han-Wook Yoo, Su Jeong You, Eun-Hye Lee, Tae-Sung Ko
Clin Exp Pediatr. 2012;55(10):397-402.   Published online October 29, 2012

Pelizaeus-Merzbacher disease (PMD) is a rare, X-linked recessive disorder characterized by dysmyelination in the central nervous system. PMD results from deletion, mutation, or duplication of the proteolipid protein gene (PLP1) located at Xq22, leading to the failure of axon myelination by oligodendrocytes in the central nervous system. PMD may be suspected when there are clinical manifestations such as nystagmus, developmental...

Neuroprotective effects of L-carnitine against oxygen-glucose deprivation in rat primary cortical neurons
Yu Jin Kim, Soo Yoon Kim, Dong Kyung Sung, Yun Sil Chang, Won Soon Park
Clin Exp Pediatr. 2012;55(7):238-248.   Published online July 17, 2012
Purpose

Hypoxic-ischemic encephalopathy is an important cause of neonatal mortality, as this brain injury disrupts normal mitochondrial respiratory activity. Carnitine plays an essential role in mitochondrial fatty acid transport and modulates excess acyl coenzyme A levels. In this study, we investigated whether treatment of primary cultures of rat cortical neurons with L-carnitine was able to prevent neurotoxicity resulting from oxygen-glucose deprivation...

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...
