Application of 3-dimensional printing implants for bone tumors
Jong Woong Park, Hyun Guy Kang
Clin Exp Pediatr. 2022;65(10):476-482.   Published online December 23, 2021
∙ The application of 3-dimensional (3D) printing in orthopedic oncology is summarized into bone and tumor modeling, patient-specific instruments (PSIs), custom-made implants, and tissue engineering.
∙ The 3D-printed customized implant is the most central application, while modeling and PSI often play adjunct roles.
∙ Short-term surgical outcomes of custom-made 3D-printed implants are promising.

The change of QRS duration after pulmonary valve replacement in patients with repaired tetralogy of Fallot and pulmonary regurgitation
Yuni Yun, Yeo Hyang Kim, Jung Eun Kwon
Clin Exp Pediatr. 2018;61(11):362-365.   Published online October 24, 2018

Purpose: This study aimed to analyze changes in QRS duration and cardiothoracic ratio (CTR) following pulmonary valve replacement (PVR) in patients with tetralogy of Fallot (TOF). Methods: Children and adolescents who had previously undergone total repair for TOF (n=67; median age, 16 years) who required elective PVR for pulmonary regurgitation and/or right ventricular out tract obstruction were included in this study....

Moon Sun Kim, Ja Kyoung Yoon, Seong Ho Kim, Ji Seok Bang, So Ick Jang, Sang Yoon Lee, Eun Young Choi, Su Jin Park, Hye Won Kwon
Clin Exp Pediatr. 2018;61(6):187-193.   Published online June 25, 2018
Purpose

The efficacy of percutaneous stent implantation for congenital heart disease (CHD) in Korea, where stent availability is limited, has not been determined. This study evaluated the acute and midterm results of stent implantation in different CHD subgroups.

Methods

Stents were implanted in 75 patients with 81 lesions: (1) pulmonary artery stenosis (PAS) group, 56 lesions in 51 patients; (2) coarctation of the...

Bo Kyung Jin, Ji Seok Bang, Eun Young Choi, Gi Beom Kim, Bo Sang Kwon, Eun Jung Bae, Chung Il Noh, Jung Yun Choi, Woong Han Kim
Clin Exp Pediatr. 2013;56(3):125-129.   Published online March 18, 2013
Purpose

The use of implantable cardioverter defibrillators (ICDs) to prevent sudden cardiac death is increasing in children and adolescents. This study investigated the use of ICDs in children with congenital heart disease.

Methods

This retrospective study was conducted on the clinical characteristics and effectiveness of ICD implantation at the department of pediatrics of a single tertiary center between 2007 and 2011.

Results

Fifteen patients underwent...

Newborn hearing screening
Lee Suk Kim
Clin Exp Pediatr. 2007;50(1):7-13.   Published online January 15, 2007
Hearing loss in newborns is the most frequently occurring birth defect. If hearing impaired children are not identified and managed early, it is difficult for many of them to acquire the fundamental language, social and cognitive skills that provide the foundation for later schooling and success in society. All newborns, both high and low risk, should be screened for hearing...

Morphologic Changes of the Pulmonary Arteries after Stent Implantation on Branch Pulmonary Artery Stenosis - Impact of Pulmonary Insufficiency -
Me Jin Kim, Du Cheol Kang, Jae Young Choi, Jong Kyun Lee, Jun Hee Sul, Sung Kyu Lee
Clin Exp Pediatr. 2003;46(1):67-75.   Published online January 15, 2003
Purpose : Intravascular stent implantation for the treatment of postoperative branch pulmonary artery(PA) stenosis has been used successfully. However, the cross sectional area of contralateral branch PA does not regress in spite of the successful dilation of the stenotic branch PA after stent implantation. We analyzed the morphologic and hemodynamic factors on the size of branch PA after successful...

Clin Exp Pediatr. 1993;36(5):687-692.   Published online May 15, 1993
A totally implanted venous access system was inserted in 19 children with cancer. The devices were utilized for the administration of antineoplastic drug, parenteral fluids, antibiotics, and blood products. Total duration of implantation was 4,046 days for 23 implanted system (range 7-445 days). Complications included cather infection (0.247/100 catheter day), occlusion (0.692/100 catheter days), and dislodgement of needle (0.643/100 catheter...
