High antistreptolysin O titer is associated with coronary artery lesions in patients with Kawasaki disease
Dong Eun Min, Do Hee Kim, Mi Young Han, Sung Ho Cha, Kyung Lim Yoon
Clin Exp Pediatr. 2019;62(6):235-239.   Published online November 7, 2018

Purpose: In Kawasaki disease (KD) patients, coronary artery complications, incomplete and refractory types occur more frequently in patients with streptococcal or other bacterial/viral infections. Recently, we observed a higher incidence of coronary lesions in KD patients with high anti-streptolysin O (ASO) titer. Therefore, we hypothesized that KD patients diagnosed with concurrent streptococcal infection have poor prognosis, with respect to treatment...
Transforming growth factor beta receptor II polymorphisms are associated with Kawasaki disease
Yu Mi Choi, Kye Sik Shim, Kyung Lim Yoon, Mi Young Han, Sung Ho Cha, Su Kang Kim, Joo Ho Jung
Clin Exp Pediatr. 2012;55(1):18-23.   Published online January 31, 2012
Purpose

Transforming growth factor beta receptor 2 (TGFBR2) is a tumor suppressor gene that plays a role in the differentiation of striated cells and remodeling of coronary arteries. Single nucleotide polymorphisms (SNPs) of this gene are associated with Marfan syndrome and sudden death in patients with coronary artery disease. Cardiovascular remodeling and T cell activation of TGFBR2 gene suggest that the...

Polymorphisms of methylenetetrahydrofolate reductase are not a risk factor for Kawasaki disease in the Korean population
Kyung Lim Yoon, Jin Hee Ko, Kye Shik Shim, Mi Young Han, Sung Ho Cha, Su Kang Kim, Joo Ho Jung
Clin Exp Pediatr. 2011;54(8):335-339.   Published online August 31, 2011
Purpose

Hyperhomocysteinemia is known as a risk factor for atherosclerosis. Preclinical arteriosclerosis is noted and premature atherosclerosis is known to be accelerated in Kawasaki disease (KD) patients. Genetic polymorphisms in the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene result in elevated plasma homocysteine concentrations and are known to be associated with the development of coronary artery disease. Our hypothesis is that single nucleotide polymorphisms...

Clin Exp Pediatr. 1994;37(6):812-815.   Published online June 15, 1994
Streptococcus pyogenes has been regarded very importantly because of its severe sequelae, namely rheumatic fever and acute glomerulonephropathy. Rapid tests to identify this organism have been studied widely in developed countries in 1980s. We proceeded the rapid test(A Strept ADTM, Denka Seiken Co., Japan) of S. pyogenes on 141 children who were known to be carriers of this organism to...

Clin Exp Pediatr. 1993;36(10):1402-1406.   Published online October 15, 1993
The vesicoureteral reflux (VUR) is frequently found among the patients with urinary tract infection (UIT) and some patients with VUR progress to reflux nephropathy. The presence of scarring at UIT is an important determinant in the selection of those at risk of progressive damage. 99m Technetium dimercaptosuccinic acid (99mTc-DMSA) is a renal scanning agent provides a good quality of renal image...

Doxorubicin is one of the most effective chemotherapeutic agents in the treatment of leukemia, lymphoma and various solid tumors. Because of dose-dependent degenerative cardiomyopathy, however, doxorubicin theraphy may be discontinued ineffectively early. Doxorubicin-induced conges- tive heart failure carries a very poor prognosis since it is lethal in 60% of patients. Various methods for evaluating the cardiotoxic effect have been employed such as EKG, systolic...
