The corrected QT (QTc) prolongation in hyperthyroidism and the association of thyroid hormone with the QTc interval
Ye Seung Lee, Joong Wan Choi, Eun Ju Bae, Won Il Park, Hong Jin Lee, Phil Soo Oh
Clin Exp Pediatr. 2015;58(7):263-266.   Published online July 22, 2015

Ventricular repolarization is assessed using the QT interval corrected by the heart rate (QTc) via an electrocardiogram (ECG). Prolonged QTc is associated with an increased risk of arrhythmias and cardiac mortality. As there have been few reports regarding the effects of hyperthyroidism on ventricular repolarization, we studied the association between serum free thyroxine (free T4 [fT4]) and thyroid stimulating hormone...

Clin Exp Pediatr. 2014;57(5):240-244.   Published online May 31, 2014

Pseudohypoparathyroidism type Ia (PHP Ia) is a disorder characterized by multiform hormonal resistance including parathyroid hormone (PTH) resistance and Albright hereditary osteodystrophy (AHO). It is caused by heterozygous inactivating mutations within the Gs alpha-encoding GNAS exons. A 9-year-old boy presented with clinical and laboratory abnormalities including hypocalcemia, hyperphosphatemia, PTH resistance, multihormone resistance and AHO (round face, short stature, obesity, brachydactyly...

Transient carnitine transport defect with cholestatic jaundice: report of one case in a premature baby
Hyun-Seok Cho, Young Kwang Choo, Hong Jin Lee, Hyeon-Soo Lee
Clin Exp Pediatr. 2012;55(2):58-62.   Published online February 14, 2012

Carnitine (β-hydroxy-γ-trimethylaminobutyric acid) is involved in the transport of long-chain fatty acids into the mitochondrial matrix and the removal of potentially toxic acylcarnitine esters. Transient carnitine transport defect is a rare condition in newborns reported in 1/90,000 live births. In this paper, we describe a case of transient carnitine transport defect found in a premature baby who had prolonged cholestatic...

Clin Exp Pediatr. 2002;45(5):659-663.   Published online May 15, 2002
β thalassemias are usually transmitted as autosomal recessive traits. However, some dominant forms of β thalassemia have been identified in individuals who have inherited a single copy of an abnormal β globin gene. Thalassemia intermedia with mild anemia, jaundice, and splenomegaly has been observed in these patients. Electrophoresis has shown elevated Hemoglobin(Hb) A2 and Hb F levels. In particular, there...

Ju Wan Kim, June Huh, Won Il Park, Kyung Ja Lee, Hong Jin Lee
Clin Exp Pediatr. 2001;44(1):94-98.   Published online January 15, 2001
Maple syrup urine disease is an autosomal recessive disease caused by a deficiency of the branched-chain α-ketoacid dehydrogenase complex. The disease is often suspected because of the peculiar odor of maple syrup in urine. Maple syrup urine disease is usually confirmed by amino acid analysis and urine organic acid analysis showing marked elevations of leucine, isoleucine, valine, and respective ketoacids in...
