Utility of a forced expiratory flow of 25 to 75 percent as a predictor in children with asthma
Jung Wan Kang, Kyung Won Kim, Eun Soo Kim, Jun Young Park, Myung Hyun Sohn, Kyu-Earn Kim
Clin Exp Pediatr. 2008;51(3):323-328.   Published online March 15, 2008
Purpose : Asthma is defined as chronic inflammation of the lower small airways, and bronchial hyperreactivity (BHR) is a pathophysiologic feature of asthma. It has been proposed that although there is no direct variable capable of assessing the small airways, a forced expiratory flow of between 25 and 75 percent (FEF25-75) might be considered a more sensitive early marker of...

Three cases of pulmonary and/or intestinal tuberculosis in adolescents
Jung Hye Byeon, Yoon Lee, Jin Chul Lee, Young Yoo, Kee Hyoung Lee, Kwang Chul Lee, Ji Tae Choung, Soo Youn Ham, Chul Whan Kim
Clin Exp Pediatr. 2007;50(11):1134-1138.   Published online November 15, 2007
Since the tuberculosis (TB) in adolescents has unique clinical characteristics, special attention should be paid to this age group. Adolescents are more susceptible to developing TB disease and more likely to have cavitary pulmonary disease. Also, adolescent patients with TB more frequently present with extrapulmonary disease. We report three adolescents with active pulmonary and/or intestinal TB: one had pulmonary and...

Clin Exp Pediatr. 2007;50(10):1030-1033.   Published online October 15, 2007
A pulmonary thromboembolism (PTE), which is a sudden blockage in a pulmonary artery, usually due to a blood clot, is rare in children. The clinical presentation is often subtle or masked by the underlying clinical condition and the condition must be suspected during clinical testing. Although the choice of treatment depends on the clinical presentation, anticoagulation is the mainstay of...

Youn Ho Shin, Ki Eun Kim, Hae Sik Kwon, Byung Won Yoo, Jae Young Choi
Clin Exp Pediatr. 2007;50(9):919-924.   Published online September 15, 2007
Pulmonary venous stenosis may be congenital or acquired. Regardless of its origin, the prognosis for patients affected with PVS remains poor. There have been many attempts to palliate PVS with little success. This report describes two patients with PVS which became evident after repair of total anomalous pulmonary venous connection. Intravascular stents were successfully implanted, but progressive restenoses in the...

Sun Ju Im, Hyun Seok Park, Hyoung Doo Lee, Jae Hong Park, Hee Ju Park
Clin Exp Pediatr. 2007;50(8):794-798.   Published online August 15, 2007
Hepatopulmonary syndrome is a triad that includes: hepatic dysfunction, intrapulmonary vascular dilatation and abnormal arterial oxygenation. The incidence of intrapulmonary vascular dilatations, in adults with end-stage liver disease, has been reported to be 13% to 47%, however the incidence in children is unclear and the cases in Korean children have never been reported. The hepatopulmonary syndrome may occur as a...

Clin Exp Pediatr. 2005;48(11):1256-1259.   Published online November 15, 2005
Pulmonary atresia with intact ventricular septum (PAIVS) is rare, less than 1% of congenital heart disease. It needs a therapeutic approach according to its individual morphologic feature. Surgical treatment of valvotomy and modified Blalock-Taussig shunt or non-surgical interventional catheter balloon valvuloplasty can be used for mild to moderate hypoplasia of right ventricle. Fontan operation can be considered for less optimum...

Clin Exp Pediatr. 2004;47(10):1119-1123.   Published online October 15, 2004
VACTERL association is a disease with multiple congenital anomalies of the vertebrae, anus, cardia, tracheoesophageal(TE) fistula, renal and limb. This disease is derived from VATER anomaly, accompanied by cardiac and limb anomalies. We experienced a case of a 1-day-old boy with anal atresia, who represented multiple anomalies during hospital course. The multiple anomalies were hemivertebra, anal atresia, complex heart disease(coarctation...

Clin Exp Pediatr. 2004;47(10):1114-1118.   Published online October 15, 2004
Congenital pulmonary vein stenosis(CPVS) with anatomically normal connection, a rare anomaly, usually leads to progressive pulmonary hypertension, cardiac failure in infancy, and death if untreated. Most are combined with other anomalies, particularly left to right shunt lesions. Very often, the detection of CPVS is overlooked on the initial cardiac echocardiogram, because it may be mild in its severity initially, but...

Clin Exp Pediatr. 2004;47(7):735-739.   Published online July 15, 2004
Purpose : Respiratory distress syndrome(RDS) is caused by a deficiency of pulmonary surfactant, which is a lipoprotein complex. Both low levels of surfactant protein A(SP-A) and SP-A alleles have been associated with RDS. However, the genes underlying susceptibility to RDS are insufficiently known. The candidate-gene approach was used to study the association between the SP-A gene locus and RDS in...

Pathophysiology of Persistent Pulmonary Hypertension of the Newborn
Yong Hoon Jun
Clin Exp Pediatr. 2004;47(7):707-715.   Published online July 15, 2004
Persistent pulmonary hypertension of the newborn(PPHN) is a disorder characterized by persistence of the pattern of fetal circulation after birth due to a sustained elevation of pulmonary vascular resistance. The two primary events in the pathophysiology of neonatal pulmonary hypertension are hypoxic pulmonary vasoconstriction(HPV) and hypoxic pulmonary vascular remodeling(HPR). Chronic hypoxemia may cause increased muscularity of the pulmonary arteries and...
New Guideline of Pediatric Cardiopulmonary Resuscitation
Yong Won Park
Clin Exp Pediatr. 2004;47(6):591-595.   Published online June 15, 2004
A primary cardiac arrest is rare in children. The usual course begins with respiratory arrest and culminates in profound bradycardia or asystole and cardiovascular collapse, so it is vitally important to quickly restore ventilation in pediatric patients(phone-fast). Children over 8 years of age follow the same sequence as adults; that is calling emergency medical services before providing rescue breathing(phone-first).
