Seon Young Cho, Jin-Hee Oh, Jung Hyun Lee, Jae Young Lee, Soon Ju Lee, Ji Whan Han, Dae Kyun Koh, Chang Kyu Oh
Clin Exp Pediatr. 2012;55(7):232-237.   Published online July 17, 2012

With feasibility in the diagnoses of congenital heart disease (CHD) in the antenatal period, we suspect changes have occurred in its incidence. No data have been reported about the current incidence of simple forms of CHD in Korea. We have attempted to assess the recent incidence and characteristics of CHD in the neonatal care unit of a secondary referral medical...

Congenital central I42hypoventilation syndrome combined with Hirschsprung disease diagnosed in the neonatal period
Jin Hyun Choi, Jin Hee Oh, Jong-Hyun Kim, Dae Kyun Koh, Seung-Chul Hong
Clin Exp Pediatr. 2006;49(4):446-450.   Published online April 15, 2006
Congenital central hypoventilation syndrome (CCHS) or Ondine's curse is a very rare sleep disorder that is the result of a congenital failure of the autonomic control of ventilation caused by insensitivity of the chemoreceptor to hypercapnea during sleep. Gastrointestinal motility disorders, particularly a congenital megacolon (Hirschsprung disease) is often combined with CCHS. This combination can be explained by a defect...
Giant Coronary and Axillary Aneurysms in an Infant with Kawasaki Disease Associated with Thrombocytopenia
Sei Young Seo, Jin Hee Oh, Jong-Hyun Kim, Ji-Whan Han, Kyung-Yil Lee, Dae Kyun Koh
Clin Exp Pediatr. 2005;48(8):901-906.   Published online August 15, 2005
Kawasaki disease (KD) is a leading cause of acquired heart disease in children. Yet the etiology of KD is still unknown and diagnosis depends on the exclusion of other diseases and the clinical manifestations meeting the defined criteria. Young infants frequently show atypical clinical courses and are frequently complicated with coronary aneurysms. Some cases show thrombocytopenia, which is known as...
A Case of Congenital Nephrogenic Diabetes Insipidus Confirmed by Gene Analysis
Eun Young Cho, Jin Hee Oh, Dae Kyun Koh
Clin Exp Pediatr. 2005;48(6):669-674.   Published online June 15, 2005
Nephrogenic diabetes insipidus (NDI) is a disorder in which the secretion of antidiuretic hormone is normal, but the response of the renal collecting tubules to vasopressin is impaired. Compared with acquired NDI (a-NDI), which is secondary to chronic bilateral incomplete urinary tract obstruction with hydronephrosis, congenital NDI (c-NDI) is a very rare heritable disorder that usually follows the X- linked...
A Case of Spinal Cord Injury without Radiographic Abnormality
Seoung Joon Kim, Dae Kyun Koh, Jin Hee Oh, Jong Hyun Kim, Jung Soo Jun
Clin Exp Pediatr. 2004;47(11):1228-1231.   Published online November 15, 2004
A spinal cord injury without radiographic abnormality(SCIWORA) was defined by Pang and Wilberger in 1982 as the "objective signs of myelopathy as a result of trauma" in which no evidence of fracture, subluxation, or instability on plain radiographs, or computed tomography is demonstrable. Inherent elasticity of the vertebral column in infants and young children, among other age-related anatomical peculiarities, render...
A Case of Epidural Emphysema Caused by Vigorous Coughing
Hye Rin Mok, Jin Hee Oh, Dae Kyun Koh
Clin Exp Pediatr. 2004;47(9):1013-1015.   Published online September 15, 2004
A 13-year-old boy was admitted via emergency room with dyspnea after vigorous coughing. Subcutaneous emphysema was palpated on both eyelids and around the neck. Breathing sound was slightly wheezy. On initial chest roentgenogram no parenchymal lesion or pneumothorax except subcutaneous emphysema on the thoracic wall was found. On the second day of hospitalization he showed agitation much more severe than...
Aplastic Crisis Secondary to Parvovirus B19 Infection
Yang Joon Park, Dae Kyun Koh, Jin Hee Oh
Clin Exp Pediatr. 2003;46(11):1139-1142.   Published online November 15, 2003
Human parvovirus(HPV) B19 infection causes erythema infectiosum in children, sometimes red cell aplastic crisis with hemolytic anemia and chronic bone marrow failure in immunocompromised hosts. HPV B19 is directly cytotoxic for erythroid progenitor cells and inhibits erythropoiesis. Infrequently, HPV B19 inhibits hematopoiesis of three cell lineages and causes transient pancytopenia in patients with hemolytic disorders. We report three patients with...

Childhood Obstructive Sleep Apnea Syndrome : Clinical and Polysomnographic Findings
Yang Jun Park, Dae Kyun Koh, Jin Hee Oh, Soo Jung Lee
Clin Exp Pediatr. 2001;44(7):786-795.   Published online July 15, 2001
Purpose : Although pediatricians may see a lot of patients with clinically suspected obstructive sleep apnea syndrome(OSAS), the actual incidence, clinical and polysomnographic manifestations of OSAS in children have not well been recognized and reported cases are rare. The objective of this study was to evaluate the efficacy of polysomnography in the diagnosis of OSAS in children and to analyze...

Dapsone in a Case with Chronic Recurrent Henoch-Schönlein Purpura
Jin Choi, Soo Jung Lee, Dae Kyun Koh
Clin Exp Pediatr. 1999;42(11):1574-1578.   Published online November 15, 1999
The most clearly delineated condition with prominent cutaneous leukocytoclastic vasculitis which presents to a pediatrician is Henoch-Schönlein purpura. There is general agreement that in Henoch-Schönlein syndrome the skin manifestations have a very benign long-term course and that corticosteroids are of little value. Dapsone appears to be of special value in diseases characterized by an accumulation of polymorphonuclear neutrophils notably leukocytoclastic...
Follow up of a Case of Primary Intestinal Lymphangiectasia
Su Jeong Ha, Soo Jung Lee, Dae Kyun Koh
Clin Exp Pediatr. 1999;42(10):1452-1458.   Published online October 15, 1999
Primary intestinal lymphangiectasia is a rare congenital disorder characterized by diffuse or localized ectasia of the enteric lymphatics, often in association with lymphatic abnormalities elsewhere in the body. The pathogenesis of these abnormal lymphatic structures is uncertain. Ectatic lymphatics may be located in the mucosa, submucosa, or subserosa, leading to a loss of protein and lymphocytes into the gut or...

Young Hee Ha, Jong Hyun Kim, Soo Joong Lee, Dae Kyun Koh
Clin Exp Pediatr. 1998;41(2):264-269.   Published online February 15, 1998
Multiple sclerosis is a chronic inflammatory demyelinating disease of the central nervous system and its lesions are multiple in time as well as space. We experienced a case of a 14-year-old-girl with dysphagia, paresthesia and headache. Brain MRI scans demonstrated high signal intensities on T2-weighted images at the medulla and upper cervical cord. Acute disseminated encephalomyelitis was diagnosed and methylprednisolone pulse...

Clin Exp Pediatr. 1994;37(9):1279-1285.   Published online September 15, 1994
Familial hemophagocytic lymphohistiocytosis (FHL) is a rare disease characterized by fever, hepatosplenomegaly, cytopenia and non-malignant lymphohistiocytic infiltration with hemophagocytosis in reticuloendothelial organs. We experienced three cases of FHL in identical male twins and their younger brother who presented with fever and severe hepatosplenomegaly. Cytompenia, elevated serum transaminase and low serum albumin levels, hypertriglyceridemia were common laboratory findings of them. One of...

The congenital hepatic fibrosis is a rare condition defined pathologically by the presence within the line of bands of fibrous tissue which after contain linear or circular spaces lined by bile duct cells, It is commonly associated with intrahepatic portal hypertension but hepatocellular function is almost always preserved. The prinicipal clinical features of this disease are abdominal distension, firm hepatomegaly,...
