Kyung Hwa Lee, Chang Woo Ha, Chul Ho Kim, Min Seob Song, Moon Su Sung
Clin Exp Pediatr. 2002;45(7):928-932.   Published online July 15, 2002
Perinatal atrial flutter is a potentially lethal arrhythmia. Management of this disorder is difficult and controversial. Fetal atrial flutter is a serious and life threatening rhythm disorder particulary when it causes hydrops; it may be associated with fetal death or neurological damage. Although the initial episode of flutter may be difficult to control, recurrence of atrial flutter after successful resolution...

Changes of Body Weight and Lipid Profiles According to Apolipoprotein E Polymorphism in Children with Antiepileptics
Seung Hee Jang, Eun Kyoung Choi, So Hee Eun, Sun Jun Kim
Clin Exp Pediatr. 2002;45(1):88-94.   Published online January 15, 2002
Purpose : Weight changes, especially weight gain, is a side effect of antiepileptics(especially valproate and carbamazepine). This may be sufficiently severe to cause noncompliance or to require the withdrawal of effective treatment. Unfortunately, the exact mechanism of weight change is not illustrated. Several reports and our experiment suggested that weight gain highly correlated with a familial tendency of obesity. The genetic makeup is a...

A Case of Protein-losing Enteropathy in Congestive Heart Failure : Resolution with Prednisolone
Jong-Woon Choi
Clin Exp Pediatr. 2001;44(5):587-591.   Published online May 15, 2001
Protein-losing enteropathy can result from primary or secondary intestinal lymphangiectasia. Secondary intestinal lymphangiectasia develops as a result of lymphatic obstruction or elevated lymphatic pressure. Cardiac lesions such as constrictive pericarditis, post-Fontan procedure state, and chronic congestive heart failure increase lymphatic pressure and may cause intestinal lymphangiectasia and protein-losing enteropathy. An 11-year-old girl who underwent corrective surgery for Tetralogy of Fallot...
