RATIONALE AND OBJECTIVES There has been little rigorous evaluation of the sonographic criteria for acute appendicitis in children. Our clinical experience has called the traditional diagnostic criteria into question. We set out to review the literature, evaluate the most commonly applied diagnostic criteria for acute appendicitis, and identify those(More)
There is heterogeneity in how pediatric voiding cystourethrography (VCUG) is performed. Some institutions, including our own, obtain a radiographic scout image prior to contrast agent instillation. To demonstrate that the radiographic scout image does not augment VCUG interpretation or contribute management-changing information but nonetheless carries a(More)
Sonography is usually requested to evaluate palpable pediatric breast lumps, and solid masses are almost always fibroadenomas. Lack of familiarity with the findings of fibroadenomas can lead to diagnostic uncertainty and sometimes unnecessary biopsy and excision. We sought to review the spectrum of sonographic findings in our cases of pathology proven(More)
OBJECTIVE To determine population-based rates of the use of diagnostic imaging procedures with ionizing radiation in children, stratified by age and sex. DESIGN Retrospective cohort analysis. SETTING All settings using imaging procedures with ionizing radiation. PATIENTS Individuals younger than 18 years, alive, and continuously enrolled in(More)
We have observed that day-to-day use of US for acute appendicitis does not perform as well as described in the literature. Review the diagnostic performance of US in acute appendicitis with attention to factors that influence performance. Retrospective review of all sonograms for acute appendicitis in children from May 2005 to May 2010 with attention to the(More)
Small bowel Crohn disease is commonly diagnosed during the pediatric period, and recent investigations show that its incidence is increasing in this age group. Diagnosis and follow-up of this condition are commonly based on a combination of patient history and physical examination, disease activity surveys, laboratory assessment, and endoscopy with biopsy,(More)
Excessive splenic mobility (i.e. wandering spleen) is a rare condition caused by laxity or deficiency of all the spleen’s normal ligamentous attachments in the left hypochondrium. In the pediatric population, a wandering spleen may present as an incidental finding, an abdominal mass or torsion of the vascular pedicle causing venous congestion and acute(More)

This study uses Mexican plant-product level data for the 1994-2003 period to examine plant behavior preceding an expansion into foreign markets. In contrast to the existing literature, which concentrates on plant productivity, we focus on domestic unit values of products that will be exported in the future and on plants' investment behavior. Our findings(More)
There is a paucity of published literature describing ultrasound (US)-US and US-MR enterography (MRE) inter-radiologist agreement in pediatric small bowel Crohn disease. To prospectively assess US-US and US-MRE inter-radiologist agreement in pediatric small bowel Crohn disease. Institutional Review Board approval and informed consent/assent were obtained(More)
OBJECTIVE The purpose of this study was to determine prospectively whether bowel wall apparent diffusion coefficient (ADC) measurements can be used to monitor treatment response to infliximab therapy in the setting of pediatric small-bowel Crohn disease. SUBJECTS AND METHODS Twenty-eight pediatric subjects with newly diagnosed biopsy-proven Crohn disease(More)
