In neonates and children, sonographic examinations of the renal pyramids may depict a spectrum of unique changes in echogenicity due to the effects of physiologic processes or a wide variety of pathologic processes that may affect the collecting ducts or interstitium of the pyramids. Focused sonographic evaluation of the pyramids with high-frequency(More)
Standardized evaluation of all newborns with antenatally recognized hydronephrosis (ANH) at The Hospital for Sick Children (HSC) has included voiding cystourethrography (VCUG). This paper reviews this protocol to determine: (1) the prevalence of vesicoureteral reflux (VUR) in isolated ANH and (2) the value of performing VCUG in cases of mild hydronephrosis,(More)
OBJECTIVE On radiographs of the abdomen and pelvis, phleboliths often have a characteristic radiolucent center that helps to distinguish them from ureteral stones. On unenhanced CT, the distinction between pelvic phleboliths and distal ureteral stones can be problematic. The objective of this study was to compare the appearance of phleboliths on routine(More)
BACKGROUND Infection continues to be a major problem for children with acute myeloid leukemia (AML). Objectives were to identify factors associated with infection, sepsis, and infectious deaths in children with newly diagnosed AML. METHODS We conducted a retrospective, population-based cohort study that included children ≤ 18 years of age with de novo,(More)
Gastrointestinal complications in pediatric acute myeloid leukemia (AML) have not been systematically described in the literature. Our objective was to describe complications related to the small and large bowel in children with AML. Literature searches were conducted of Ovid Medline from 1950 to November 2009 and EMBASE from 1980 to November 2009. We(More)
Embryonal rhabdomyosarcoma (ERMS), a soft tissue sarcoma, is one of the most common pediatric cancers. Certain ERMSs are associated with the DICER1 syndrome, a tumor predisposition syndrome caused by germ-line DICER1 mutations. Characteristic somatic mutations have also been identified in DICER1-associated tumor types. These "hotspot" mutations affect the(More)
OBJECTIVE To describe the long-term outcomes of pediatric pleural empyema. DESIGN Prospective observational study from October 2008 to October 2011. SETTING Tertiary care children's hospital. PARTICIPANTS Children with pleural empyema (loculations and/or septations identified on radiologic imaging or frank pus on thoracentesis). MAIN OUTCOME(More)
PURPOSE To examine predictors of a false-positive (FP) result on contrast enema (CE) for the diagnosis of Hirschsprung disease (HD). METHODS Retrospective analysis, over a 5-year period (1999-2004), of infants (<6 months of age) with suspected HD undergoing rectal biopsy following abnormalities identified on CE (transition zone [TZ], abnormal rectosigmoid(More)
Cystic mesenteric lymphatic malformations are uncommon abdominal masses, which can cause abdominal signs and symptoms for a wide variety of reasons. Symptoms owing to volvulus are uncommon and have not been illustrated previously in the radiology literature. We present two cases to illustrate volvulus as a complication of mesenteric lymphatic malformations(More)
