The purpose of this study was to evaluate and assess the compatibility of current risk scoring systems from Japan that were developed to predict intravenous immunoglobulin (IVIG) resistance in patients with Kawasaki disease (KD). The authors previously investigated another prediction model for patients with refractory KD in Korea. A retrospective study involving 350 patients with KD who were admitted between January 2014 and December 2015 was performed. Patients younger than 2 years were exclude

Purpose: As cardiomyopathy is more prevalent and currently the leading cause of death in Duchenne muscular dystrophy (DMD),early detection of myocardial involvement is important. The purpose of this study was to analyze myocardial strain in DMD children,for the possibility of early detection of myocardial dysfunction. Materials and Methods: We reviewed medical records of DMD patients who were >10 years of age (15.6±1.6 years, 12.5–18 years),from March 2013 to June 2014. Data of 24 DMD children w

A 29-year-old woman was referred to our institute for symptomatic hypoxemia. Her dyspnea was aggravated while sitting or standingand relieved while in supine position. She did not have any pulmonary disease. Transthoracic echocardiography and heart computed tomographyrevealed an underestimated small atrial septal defect (ASD) with a left-to-right shunt. A cardiac catheterization was performedto evaluate pulmonary hypertension. It revealed a normal pulmonary artery pressure and a large ASD with b

Purpose : We investigated the causative organism and its antibiotic susceptibility of community acquired urinary tract infection (UTI) in children at a secondary hospital to test the adequacy of the current guidelines. Methods : Children diagnosed with UTI at the Department of Pediatrics, Kwandong University MyMyongji Hospital by pyuria and bacterial growth of greater than on clean catch midstream urine from January 2005 to December 2008 were studied retrospectively. The epidemiologic data, caus

Purpose: Children with mitochondrial disease (MD) have clinical phenotypes that are more severe than those found in adults. In this study, we assessed cardiac function in children with MD using conventional and advanced echocardiographic measurements, explored any unique patterns present, and investigated the development of early cardiomyopathy (CMP). Materials and Methods: We retrospectively reviewed the medical records of 33 children with MD. All patients underwent transthoracicechocardiograph

Background: In adults, tissue Doppler imaging (TDI) is a recommended component of routine echocardiography. However,TDI velocities are less accepted in pediatrics, due to their strong variability and age dependence in children. This study examines thedistribution of myocardial tissue Doppler velocities in healthy children to assess the effect of age with cardiac growth on the variousechocardiographic measurements. Methods: Total 144 healthy children were enrolled in this study. They were recruit

Coronary artery involvement remains the most important complication with Kawasaki disease (KD). Additional myocardial injury can be caused by inflammatory response and ischemic event. However, the long-term outcome of myocardial function has not been fully known in KD. The purpose of this study is to evaluate myocardial function in school-aged children who had the past history of KD. Sixty-seven children in the second grade of elementary schools, who had the past history of KD, were included. Ec

Background: The speckle tracking echocardiography can benefit to assess the regional myocardial deformations. Although,previous reports suggested no significant change in left ventricular (LV) torsion with aging, there are certain differences in LV rotationat the base and apex. The purpose of this study was to evaluate the change and relationship of LV rotation for torsion withaging in children. Methods: Forty healthy children were recruited and divided into two groups of twenty based on whether

Purpose: Idiopathic scoliosis is a structural lateral curvature of the spine of unknown etiology. The relationship between degree of spine curvature and cardiopulmonary function has not yet been investigated. The purpose of this study was to determine the association between scoliosis and cardiopulmonary characteristics. Methods: Ninety children who underwent preoperative pulmonary or cardiac evaluation at a single spine institution over 41 months were included. They were divided into the thorac

심장질환 진단을 위한 다양한 영상 장치가 있지만 작은 병변 또는 경미한 단계의 질환을 발견하는 것은 어렵다. 본 연구에서는 심장질환에 의한 미세한 심장 조직 변화를 분석할 수 있는 고주파 초음파 횡파 영상 시스템을 제안한다. 제안된 시스템은 작은 병변을 감지할 수 있도록 높은 해상도의 영상을 얻기 위하여 38MHz 초음파 변환자를 제작 이용하였고, 조직 내의 충분한 횡파의 발생을 위해 기계적 진동기를 사용하였다. 시스템의 성능 확인을 위해 팬텀을 이용하여 심장의 횡 방향/ 축 방향 분해능을 측정하였고, 해상도는 각각 144µm 와 168µm가 측정되었다. 시스템의 유효성 확인을 위해 돼지 심장을 이용한 체외 실험을 수행하였다. 돼지 심장 실험은 정상 심장 조직을 국소적으로 냉각 및 가열시킨 후 실험하였고, 본 시스템으로 심장조직의 국소적 변화를 관찰할 수 있었다. 따라서 향후 본 연구에서 제안하는 영상 시스템을 적용한 임상연구를 거쳐 심장질환 조기진단이 가능하게 될 것이다.

Background:Echocardiographic examination is universally considered as an established method for the diagnosis of congenital heart disease, and as a result of many technological advancements in information processing, its utility is being emphasized much more. Cardiac catheterization, by comparison, is usually performed in the past for the purpose of diagnosis and preoperative assessment of infants with isolated ventricular septal defect (VSD), and the risks and complications of cardiac catheteri

Kawasaki disease (KD) is a common febrile disease in East Asia. Because KD with coronary artery aneurysm (CAA) may predispose to thrombosis, children with KD-associated CAA may need anticoagulation in addition to aspirin. In this report, we describe a 6-year-old girl with KD and CAA who was found to have unexpected warfarin-induced coagulopathy caused by CYP2C9 and VKORC1 genotype variants, which affect warfarin metabolism.

Purpose: Mitochondrial disease (MD) and Duchenne muscular dystrophy (DMD) are often associatedwith cardiomyopathy, but the myocardial variability has not been isolated to a specific characteristic. We evaluated the left ventricular (LV) mass by echocardiography to identify the general distribution andfunctional changes of the myocardium in patients with MD or DMD. Methods: We retrospectively evaluated the echocardiographic data of 90 children with MD and 42with DMD. Using two-dimensional echocar
