Voiding cystourethrogram--are our protocols the same?

Purpose: Voiding cystourethrogram is the gold standard for evaluating and diagnosing vesicoureteral reflux. Reflux detection can potentially be affected by many parameters during voiding cystourethrogram.

Materials And Methods: A 29-item survey was sent via e-mail through SurveyMonkey® to the chairperson of pediatric radiology at 65 national pediatric hospitals.

Sonographic evaluation of pediatric localized scleroderma: preliminary disease assessment measures.

Background: Our earlier work in the ultrasonograpy of localized scleroderma (LS) suggests that altered levels of echogenicity and vascularity can be associated with disease activity. Utrasound is clinically benign and readily available, but can be limited by operator dependence. We present our efforts to standardize image acquisition and interpretation of pediatric LS to better evaluate the correlation between specific sonographic findings and disease activity.

A favorable outcome following 32 vesicocentesis and amnioinfusion procedures in a fetus with severe prune belly syndrome.

Patients with severe prune belly syndrome rarely survive beyond the first days of life. We present a case of prune belly syndrome that initially presented with severe oligohydramnios, megacystis and associated poor urine biochemistries. Due to an anteriorly located placenta the patient was referred to three major centers, but was turned down because of the unfavorable prognostic findings.

De novo three-way chromosome translocation 46,XY,t(4;6;21)(p16;p21.1;q21) in a male with cleidocranial dysplasia.

Cleidocranial dysplasia (CCD) is an autosomal dominant skeletal dysplasia associated with cranial, clavicular, and dental anomalies. It is caused by mutations in the RUNX2 gene, which encodes an osteoblast-specific transcription factor and maps to chromosome 6p21. We report clinical and molecular cytogenetic studies in a patient with clinical features of CCD including wormian bones, delayed fontanel closure, hypoplastic clavicles and pubic rami, and supernumerary dentition.

Qualitative assessment of cervical spinal stenosis: observer variability on CT and MR images.

Background And Purpose: Several studies have been undertaken to validate quantitative methods of evaluating cervical spinal stenosis. This study was performed to assess the degree of interobserver and intraobserver agreement in the qualitative evaluation of cervical spinal stenosis on CT myelograms and MR images.

Methods: Cervical MR images and CT myelograms of 38 patients were evaluated retrospectively.
