The objective of this study was to identify causes irreducible intussusception after contrast enema and correlate imaging findings with surgical histopathologic findings.Between 2005 2013, a total 543 children underwent reduction the use an technique (hereafter referred as "enema reduction"). medical records 72 (56 boys [mean age, 24.8 months; range, 3.8 months 10.9 years] 16 girls 14.2 1.5 6.9 years) who unsuccessful were treated surgically retrospectively analyzed. data collected included...
Abstract The SOX2 transcription factor is expressed early in the embryonic stem cells of blastocyst and later neural cells. It a member SOX family proteins that carry DNA‐binding high‐mobility group domain additional domains regulate development cell fate determinations. We surveyed 93 patients with severe eye malformations for mutations . Here, we report novel nonsense mutation one female patient bilateral clinical anophthalmia, absence all optic pathways, other neurological abnormalities....
Of patients admitted to hospital with sinusitis, about 3% have an intracranial complication. We describe the clinical features, laboratory data, imaging findings, and outcomes of pediatric complications sinusitis.A retrospective chart review all < 21 years age for sinusitis a tertiary over 10-year period.A total 13 mean 13.3 ± 3.7 presented headache (92%), fever (85%), nausea/vomiting (62%), sinus tenderness (31%), lethargy (23%). Physical examination findings included Pott puffy tumor...
The objective of our study was to determine the effect mAs and kVp reduction on pediatric phantoms based patient circumference optimize dose maintain image quality for abdominal CT.Three polymethylmethacrylate right cylindric CT index (CTDI) with diameters 10, 16, 32 cm simulated abdomen an infant, child, adolescent, respectively. Using a National Institute Standards & Technology ion chamber Victoreen 660 electrometer, doses at centerline were recorded 16-MDCT scanner. Measurements obtained...
To a) describe superior mesenteric artery resistive index, as an estimate of perfusion, before and after modified Norwood; b) assess incidence diastolic flow reversal in the Norwood.Prospective observational trial.Children's hospital pediatric intensive care unit.Ten newborns with hypoplastic left heart syndrome.Ultrasound documentation direction measurement index 24-48 hrs Norwood.Seven males three females were enrolled. There was no change between pre- vs. postoperatively-0.99 (95%...
This CT study evaluates image noise and radiation dose using a modified index phantom to approximate pediatric abdominal shape. Contrast-to-noise ratio (CNR) were measured.The oval shape was simulated by fixing 1000-mL saline bags aside cylindric phantoms with variable circumferences. The doses at the center peripheral holes in recorded. Measurements obtained 50-400 mAs 80-140 kVp. Diluted iodine contrast agent filled hole, distilled water holes. CNR defined as difference number between...
Mutations in the smooth muscle–specific isoform of α-actin ( ACTA2) cause vascular muscle dysfunction leading to aortic aneurysm and moyamoya syndrome. A unique R179H mutation ACTA2 has been reported result widespread affecting extravascular muscles. We report a 7-year-old girl with an manifesting neonatal seizures due multifocal infarcts, asymmetric motor deficits, global developmental delay, spasticity, congenital bilateral mydriasis, large patent ductus arteriosus. Serial magnetic...
The purpose of this study is to describe and implement a new fast three-point Dixon MR imaging sequence with online image reconstruction, compare conventional chemical shift selective (CHESS) suppression fat in pediatric musculoskeletal imaging.A technique using spin-echo phase-correction algorithm providing reconstruction was implemented on 1.5-T scanner. Twelve patients young adults were imaged both the CHESS sequences. Three radiologists un-aware parameters clinical information...
The objective of the present study was to validate use web-based tutorials teach technical skills in pediatric ultrasound.A series 10 video tutorials, each which less than minutes long, created improve education radiology trainees terms their ultrasound technique. Pediatric fellow from our institution United States and resident partner Ethiopia were invited participate study. Validation performed using two learning modules that focused on renal bladder right upper quadrant (RUQ). Pretest...
Aicardi syndrome was originally described as a triad of partial or complete agenesis the corpus callosum, infantile spasms, and pathognomic chorioretinal lacunae. Of approximately 200 cases reported since it in 1965, there have been no undisputed reports 46 XY male. Thus dominant X-linked inheritance, presumed lethal males, has proposed. Herein we report 5 year-old male with classic clinical syndrome.
