In infants with febrile urinary tract infection (UTI), the accurate rapid diagnosis of acute pyelonephritis (APN) would be valuable because early aggressive treatment reduces the risk of renal scarring. The objective of the study was to evaluate whether rapid plasma neutrophil gelatinase-associated lipocalin (NGAL) assay could be used as a diagnostic(More)
PURPOSE To compare intravoxel incoherent motion diffusion weight imaging IVIM-DWI MRI with DMSA for the evaluation of cortical defect in pediatric upper urinary tract infection (UTI) patients. MATERIALS AND METHODS Forty-three kidneys of 22 pediatric patients with the first episode of febrile upper UTI were evaluated. DWI using IVIM model was performed(More)
AIM To evaluate the maximal-outer-diameter (MOD) and the maximal-mural-thickness (MMT) of the appendix in children with acute appendicitis and to determine their optimal cut-off values to diagnose acute appendicitis. METHODS In total, 164 appendixes from 160 children between 1 and 17 years old (84 males, 76 females; mean age, 7.38 years) were examined by(More)
To compare the diffusion parameters of intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) between the “reflux” and the “non-reflux” kidneys, and to evaluate the feasibility of using IVIM DWI to predict vesicoureteral reflux (VUR) in children with a urinary tract infection (UTI). Eighty-three kidneys from 57 pediatric patients with a UTI(More)
OBJECTIVE To investigate the relationship between a chronic obstructive pulmonary disease (COPD) candidate gene, based on a genomewide association study, and computed tomographic (CT) quantitative analysis; and to find a phenotype in the COPD candidate FAM13A gene. MATERIALS AND METHODS This study was conducted in subclinical male smokers between 2 groups(More)
BACKGROUND AND PURPOSE Ultrasound has been used successfully to differentiate benign and malignant breast lesions. The aim of this study was to investigate the correlation between ultrasound and prognostic indicators in breast cancer such as histological type, tumor grade, and biological markers. MATERIALS AND METHODS Ultrasound findings (shape, margin,(More)
Here we report the first case of a Korean infant with a cloverleaf-shaped craniosynostosis, in which the diagnosis of Beare-Stevenson syndrome was suspected upon observation of the typical morphological features. This infant exhibited craniofacial anomalies, ocular proptosis, cutis gyrata, acanthosis nigricans, prominent umbilical stump, furrowed palms and(More)
Infectious diseases precede a significant proportion of acute ischemic strokes in children. Here, we report a case of acute ischemic stroke in a 3-year-old girl with a Mycoplasma pneumonia-associated respiratory tract infection. She developed an acquired prothrombotic state of protein S deficiency and had increased fibrinogen and fibrinogen degradation(More)
Scrotal involvement is a rare complication of acute pancreatitis. It presents as scrotal swelling and skin color change, which mimics the presentations of testicular torsion, epididymitis, and testicular tumor. Its differential diagnosis is important because scrotal involvement of acute pancreatitis can be treated conservatively. Abdominopelvic CT provides(More)
OBJECTIVE To investigate the distinctive computed tomographic(CT) features of pyogenic liver abscess (PLA) caused by Klebsiella pneumoniae (KLA). METHODS 114 PLA patients (62 men, 52 women, age range 25-89 years, mean age 60.9 years) with positive yield of blood or pus cultures were divided into 2 groups; KLA group (n = 58) and non-KLA group (n = 56). We(More)
