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... |
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... |
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... |
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... |
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... |

Methods : Forty preterm newborns whose mothers received antenatal care at Ewha Womans University Mokdong Hospital between January 2003 to June 2005, and... |
Systemic arterial supply from the aorta to the lung is a rare congenital anomaly within the spectrum of bronchopulmonary sequestration according to Pryce's terminology. We describe our experience of this anomaly in an infant with congenital cardiac disease confirmed by multidetector CT scan. We found a systemic arterial supply from the aorta to the right lower lobe of lung without... |
Purpose : The purpose of this study is to determine whether the new pulmonary valve reconstruction technique prevents short-term postoperative pulmonary regurgitation and improves early and mid-term clinical outcome. Methods : We reviewed postoperative echocardiographic variables and chest X-ray films from 31 patients who had undergone valve reconstruction(pulmonary valve reconstruction group : PVR) for the repair of TOF between April 2000... |
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... |
Purpose : Forward pulmonary blood flow may be absent in some neonates with Ebstein's anomaly by anatomical or functional pulmonary atresia in association with the elevated pulmonary vascular resistance, patent ductus arteriosus and tricuspid regurgitation. We reviewed the presentation and outcomes of symptomatic neonates with Ebstein's anomaly focusing on the pulmonary atresia. Methods : Clinical presentation and outcome of 15 symptomatic... |
Purpose : Obesity is associated with disturbances of ventilatory functions in adults. But few studies have evaluated the pulmonary complications of obesity in the pediatric population. The purpose of this study is to clarify the effects of obesity on pulmonary function and body composition in obese children. Methods : Forty seven obese children whose ages ranged from nine to twelve... |
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... |
Pulmonary arteriovenous fistulas(PAVFs) is a rare disorder that occurs in two to three children per 100,000 population. It is presented as absence of intervening capillary beds between the pulmonary artery and vein with resultant persistent right to left shunt. Other causes include trauma, liver cirrhosis, malignancy and schistosomiasis. It is mostly asymptomatic, but it may present with respiratory difficulty, cyanosis,... |
Fetal alcohol syndrome can be suspected in infants born to mothers with a prenatal history of alcohol abuse if the child exhibits characteristic facial features, together with intrauterine growth retardation, multiple neurological abnormalities, and multiorgan defects. If only a few of the above criteria are satisfied, the term fetal alcohol effects is used. We experienced a neonate who presented with... |
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... |
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... |
Anomalous left pulmonary artery(pulmonary artery sling) is a congenital anomaly in which the vascular structure arises either from the posterior surface of the right pulmonary artery, or from the main pulmonary artery and courses to the left lung between the posterior surface of the trachea and the anterior surface of the esophagus. It may compress on the tracheobronchial tree causing... |

Lung development is a sum of processes that involve harmonized orchestration of expressions of various factors in time and space. The mastermind governing these phenomena is not known, but cumulative efforts so far have helped us gain some insights as to what are involved in and how complex the developmental process is. Beginning as primitive foregut, lungs undergo processes called... |
Purpose : Surfactant replacement therapy in neonates with respiratory distress syndrome(RDS) has been used in Korea since 1990. We undertook a collective study of trials from multi-hospitals to evaluate results of neonates with RDS who were treated with surfactant during the past 15 years in Korea(Period I, P-I, 1990-91; Period II, P-II, 1996; Period-III, P-III; 2002). Methods : There were 60... |
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... |
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... |
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). |
Purpose : The purpose of this study is to help determine the optimal time and method for operation of pulmonary atresia(PA) with ventricular septal defect(VSD).
