BACKGROUND: Developmental dysplasia of the hip (DDH) is known to result in smaller femoral head size in toddlers; however, alterations in femoral head size and growth have not been documented in infants. OBJECTIVE: To determine with ultrasound (US) whether femoral head size and growth are altered in infants (younger than 1 year of age) with severe DDH. MATERIALS AND METHODS: We identified all patients at our tertiary care children's hospital from 2002 to 2014 who underwent US for DDH...

BACKGROUND: Peripherally inserted central catheters (PICCs) represent a mainstay of intravascular access in the neonatal intensive care setting when long-term vascular access is needed. Ideally, PICCs should be inserted and maintained in a central position with the tip ending in the superior or inferior vena cava. This is not always achievable, and sometimes the tip remains in a peripheral location. Higher complication rates have been reported with non-central PICCs; however these findings have not been confirmed in a solely neonatal series and PICCs with tips in peripheral veins have not been studied...

Yoshiko Matsubara, Osamu Miyazaki, Motomichi Kosuga, Torayuki Okuyama, Shunsuke Nosaka
BACKGROUND: Although enzyme replacement therapy (ERT) is an effective treatment for mucopolysaccharidosis (MPS) types I, II, IVA and VI, its effectiveness in children with central nervous system (CNS) disorders is said to be poor because the blood-brain barrier cannot be penetrated by ERT drugs. OBJECTIVE: To assess CNS involvement in mucopolysaccharidosis at the start of enzyme replacement therapy and to investigate the time course of ERT in the central nervous system...

Kathleen Schenker, Steven Blumer, Diego Jaramillo, Amanda L Treece, Aashim Bhatia
BACKGROUND: Epithelioid hemangioma is a rare vascular tumor that can occur in soft tissues or bone. The tumor is part of a spectrum of vascular tumors that also includes epithelioid hemangioendothelioma and angiosarcoma. When involving the bone, the tumor usually involves the metaphysis or diaphysis of the long tubular bones and most commonly occurs in adults. It has been rarely reported in pediatric patients, and in these reported patients, the tumor primarily involves the epiphysis...

Andy Tsai, Brittany Coats, Paul K Kleinman
BACKGROUND: The classic metaphyseal lesion (CML) is strongly associated with infant abuse, but the biomechanics responsible for this injury have not been rigorously studied. Radiologic and CT-pathological correlates show that the distal tibial CML always involves the cortex near the subperiosteal bone collar, with variable extension of the fracture into the medullary cavity. Therefore, it is reasonable to assume that the primary site of bone failure is cortical, rather than intramedullary...

BACKGROUND: Peripherally inserted central catheters (PICCs) can lead to development of venous thrombosis and/or stenosis. The presence of venous thrombosis and/or stenosis may preclude children with chronic medical conditions from receiving lifesaving therapies, from hemodialysis in end-stage renal disease to total parenteral nutrition in short bowel syndrome. Several adult studies have found an association between PICCs and venous thrombosis and/or stenosis, but none has evaluated for this association in children...

#11
Xinhua Cao, Xiaoyin Xu, Laura Drubach, Frederic H Fahey
BACKGROUND: When performing dynamic gastric emptying scintigraphy with continuous acquisition in children, a single posterior view acquisition is preferred because it allows the young patient to more easily interact with a parent or technologist even though this method tends toward overestimating gastric emptying. OBJECTIVES: The objective of our study was to develop a new attenuation correction (AC) method to improve the accuracy of the time activity curve and the measurement of residual gastric emptying from 1-h posterior images of gastric emptying scintigraphy with continuous acquisition...

BACKGROUND: Intussusception is one of the most common causes of acute abdominal emergency in children. Image-monitored pressure reduction is the first line of treatment. OBJECTIVE: We report on a modified technique of air delivery during fluoroscopic-monitored pneumatic intussusception reductions, and compare it with an established technique. MATERIALS AND METHODS: We modified the Shiels intussusception reduction device so that the air used for intussusception reduction is delivered not by the device's insufflator bulb, but rather by the hospital medical air supply system, eliminating the need for continuous pumping of the insufflator bulb during the procedure...

BACKGROUND: Postmortem CT is a relatively new field of interest within paediatric radiology. This paper focusses on its value in cases of unexpected natural death. OBJECTIVE: We report on an observational Dutch study regarding the value of postmortem CT in children with an assumed natural unexpected death because postmortem CT is part of the Dutch NODO (additional investigations of cause of death) procedure. MATERIALS AND METHODS: We included consecutive children who fulfilled criteria for the NODO procedure and were therefore referred to one of the centres for the procedure...

BACKGROUND: Full iterative reconstruction algorithm is available, but its diagnostic quality in pediatric cardiac CT is unknown. OBJECTIVE: To compare the imaging quality of two algorithms, full and hybrid iterative reconstruction, in pediatric cardiac CT. MATERIALS AND METHODS: We included 49 children with congenital cardiac anomalies who underwent cardiac CT. We compared quality of images reconstructed using the two algorithms (full and hybrid iterative reconstruction) based on a 3-point scale for the delineation of the following anatomical structures: atrial septum, ventricular septum, right atrium, right ventricle, left atrium, left ventricle, main pulmonary artery, ascending aorta, aortic arch including the patent ductus arteriosus, descending aorta, right coronary artery and left main trunk...
