Case Report
Pulmonary hypertension due to obstructive sleep apnea in a child with Rubinstein-Taybi syndrome
Hyung Soon Choi, Jeong Jin Yu, Young-Hwue Kim, Jae-Kon Ko, In-Sook Park
Clin Exp Pediatr. 2012;55(6):212-214.   Published online June 21, 2012

Rubinstein-Taybi syndrome (RTS) is characterized by peculiar facies, mental retardation, broad thumbs, and great toes. Approximately one-third of the affected individuals have a variety of congenital heart diseases. They can also have upper airway obstruction during sleep, due to hypotonia and the anatomy of the oropharynx and airway, which make these patients susceptible to obstructive sleep apnea (OSA). In our...

Diagnosis of incomplete Kawasaki disease
Jeong Jin Yu
Clin Exp Pediatr. 2012;55(3):83-87.   Published online March 16, 2012

Several authors suggested that the clinical characteristics of incomplete presentation of Kawasaki disease are similar to those of complete presentation and that the 2 forms of presentation are not separate entities. Based on this suggestion, a diagnosis of incomplete Kawasaki disease in analogy to the findings of complete presentation is reasonable. Currently, the diagnosis of incomplete Kawasaki disease might be...

Log-transformed plasma level of brain natriuretic peptide during the acute phase of Kawasaki disease is quantitatively associated with myocardial dysfunction
Sunhee Bang, Jeong Jin Yu, Myung-Ki Han, Hong Ki Ko, Sail Chun, Hyung Soon Choi, Young-Hwue Kim, Jae-Kon Ko, In-Sook Park
Clin Exp Pediatr. 2011;54(8):340-344.   Published online August 31, 2011
Purpose

Brain natriuretic peptide (BNP) has been considered a biochemical marker for myocarditis in Kawasaki disease. We performed this study to determine its quantitative significance.

Methods

We attempted to correlate log-transformed BNP concentrations (log-BNP) and clinical, laboratory, and echocardiographic variables in 81 children with Kawasaki disease. Stepwise multiple linear regression analysis was used to determine the variables independently associated with log-BNP concentration.

Results

Serum C-reactive...
