Headache is a common complaint in pediatric office practices as well as in children presenting to emergency departments. Children who complain of headache usually are brought to medical attention by their parents, who seek reassurance that the headaches are not a sign of a serious illness. The etiologies of headache range from school problems to brain tumors. A history taking,...

Constipation in Children
Jae Young Kim
Korean J Pediatr. 2005;48(4):355-362.   Published online April 15, 2005
Constipation is very common phenomenon during childhood that accounts approximately 3% of general pediatric outpatient visits and up to 25% of visit to the pediatric gastroenterologist. The diagnosis of functional constipation is based on the historical features and absence of physical abnormalities. Most infants and children with chronic constipation require no diagnostic tests. Constipation and subsequent fecal retention behavior often...

Human Surfactant Protein-A(SP-A) Gene Locus Associated with Mycoplasma pneumoniae Pneumonia in Korean Children
Seung Soo Kim, In Kyu Lee, Jung Ho Ko, Myung Ho Oh, Chong Woo Bae
Korean J Pediatr. 2005;48(4):376-379.   Published online April 15, 2005
Purpose : Mycoplasama pneumoniae is a leading cause of pneumonia and exacerbates other respiratory conditions such as asthma. Surfactant protein A(SP-A) is involved in surfactant physiology and surfactant structure, and plays a major role in innate host defense and inflammatory processes in the lung. In this study, SP-A mediated mycoplasma cidal activity. The candidate-gene approach was used to study the...
The Association of Neonatal Hyperbilirubinemia with UGT1A1 and CYP1A2 Gene Polymorphism in Korean Neonates
Hoon Kang, Jun Ho Lim, Ji Sook Kim, Eun Ryoung Kim, Sung Do Kim, Hee Jae Lee, Joo Ho Chung
Korean J Pediatr. 2005;48(4):380-386.   Published online April 15, 2005
Purpose : The incidence of nonphysiologic neonatal hyperbilirubinemia is twice as high in East Asians as in whites. Recently, UGT1A1 mutation was found to be a risk factor for neonatal hyperbilirubinemia. In congenitally-jaundiced Gunn rats, which lack expression of UDP-glucuronosyltransferase, alternative pathways can be stimulated by inducers of CYP1A1 and CYP1A2 enzymes. CYP1A2 plays a major role in bilirubin degradation...

Korean J Pediatr. 2005;48(4):395-400.   Published online April 15, 2005
Purpose :Rotavirus is one of the most important causes of nosocomial infections among children. The aim of this study is to determine the risk of nosocomial rotavirus infections and to evaluate the effectiveness of breast-feeding and probiotics in the prevention of nosocomial rotavirus infections. Methods : This study was carried out on admitted children without diarrhea between March 1, 2003 and...
Clinical Study of Children Using Home Mechanical Ventilation
Young Joon Ahn, Seung Hyeon Lee, Hyo-Bin Kim, Seong Jong Park, Tae Sung Ko, Soo-Jong Hong
Korean J Pediatr. 2005;48(4):401-405.   Published online April 15, 2005
Purpose : The use of mechanically-assisted ventilators at home reduces morbidity and improves the quality of life in children with chronic respiratory failure. But in Korea there is no clinical data of children with home mechanical ventilation. We investigated ventilator types, duration, the causes of failure or death, and the cost needed for care. Methods : We retrospectively analyzed the medical...
The Effect of Anticonvulsants on Serum Copper and Zinc Concentrations
Hee Jeong Jeong, Hye Won Youn, Keon Su Lee
Korean J Pediatr. 2005;48(4):406-410.   Published online April 15, 2005
Purpose : Anticonvulsants have a number of side effects and some of them may be attributed to a disturbance of serum trace metal homeostasis. Although they are minor building components in tissues, they play important functional roles in the peripheral and central nervous system. We measured serum copper and zinc levels in epileptic children who were treated with anticonvulsants to...
Expression of Nerve Growth Factor during Urinary Bladder Development
Kyoung Eun Lee, Chang Hee Hong, Hee Jung Kang, Dug Ha Kim
Korean J Pediatr. 2005;48(4):411-415.   Published online April 15, 2005
Purpose : This study was performed to determine the developmental expression pattern of nerve growth factor(NGF) in the urine of healthy children. It was hypothesized that NGF may contribute to the development of the spinobulbospinal micturition reflex that represents the adult micturition pattern. Methods : Voided urine was collected in 60 healthy children during the first 5 years of life(0-1 month,...

The present study was performed to verify if polyglutamine disease transgenic Drosophila models show similar dysfunctions as are seen in human patients. Methods : Polyglutamine disease transgenic Drosophila were tested for their climbing ability. And using genetic methods, the effects of...
Case Reports

Korean J Pediatr. 2005;48(4):433-437.   Published online April 15, 2005
Bezoars are concretions commonly found in the stomach and small bowel, and four types of bezoars have been described based on their composition : trichobezoar, phytobezoar, lactorbezoar, and miscellaneous. Bezoars most often develop after gastric operations that alter the motility, emptying, and grinding of food in the stomach. Trichobezoars are most common in female children with normal gastrointestinal function and...

Se Min Lee, So Eun Park, Yeun Woo Kim, Jung Yeun Hong
Korean J Pediatr. 2005;48(4):438-442.   Published online April 15, 2005
Kawasaki disease is an acute febrile vasculitis that occurs predominantly in young children under 5- years-old. The patients present generally with a high spiking fever that is unresponsive to antibiotics and lasts for more than five days at least. Prolonged fever has been shown to be a risk factor in the development of coronary artery disease. It seems to be...

Korean J Pediatr. 2005;48(4):443-447.   Published online April 15, 2005
Castleman's disease is a rare non-neoplastic lymphoproliferative disorder of unknown etiology. It is divided into three histologic subtypes; hyaline-vascular(HV), plasma cell(PC) type and mixed type (HV-PC). It has two clinical expressions. The localized form, which presents as a slow growing mass, has a relatively benign clinical course. The multicentric form is multilocated and holds significant morbidity. The mainstay of treatment...
