Anatomic distribution of cervicofacial lymphatic malformations based on lymph node groups.

Objectives: To evaluate radiographic characteristics and to identify locations of cervicofacial lymphatic malformations in children based on known lymph node groupings.

Methods: Retrospective chart review of pediatric patients with cervicofacial lymphatic malformations who underwent imaging with magnetic resonance imaging (MRI), computed tomography (CT) or ultrasonography (US). Ninety charts were reviewed from November 2005 to June 2015.

Fibro-adipose vascular anomaly: clinical-radiologic-pathologic features of a newly delineated disorder of the extremity.

Background: The diagnosis and management of vascular anomalies of the extremities can be challenging as these disorders are uncommon and may clinically overlap. The aim of this paper is to describe the clinical, radiologic, and histopathologic features of fibro-adipose vascular anomaly (FAVA), a previously unrecognized disorder of the limb.

Methods: The clinical, imaging, operative, and histopathologic data from patients with a unique intramuscular lesion of the extremities comprising dense fibrofatty tissue and slow-flow vascular malformations were retrospectively reviewed.

Intranodal lymphangiography: feasibility and preliminary experience in children.

Purpose: To review an initial experience studying the lymphatic system using direct injection of ethiodized oil contrast medium into lymph nodes (ie, intranodal lymphangiography) in children with chylous disorders.

Materials And Methods: Children with chylous disorders who underwent intranodal lymphangiography were included in this retrospective study. Under general anesthesia, ultrasonography was used to guide the placement of a small-bore (22-25-gauge) needle into an inguinal lymph node.

Pulmonary CT angiography to evaluate for pulmonary embolism in children visiting adult-centered community hospitals.

Objective: The objective of our study was to determine the rate of pulmonary embolism (PE) on pulmonary CT angiography (CTA) in children and adolescents visiting adult-centered community hospitals. We also investigated alternative diagnoses that may account for presenting symptoms.

Materials And Methods: We identified consecutive children and adolescents (age ≤ 19 years) who underwent pulmonary CTA during a 12- and 24-month period, respectively, at two community hospitals.

Variability in imaging utilization in U.S. pediatric hospitals.

Background: Use of medical imaging is under scrutiny because of rising costs and radiation exposure. We compare imaging utilization and costs across pediatric hospitals to determine their variability and potential determinants.

Materials And Methods: Data were extracted from the Pediatric Health Information System (PHIS) database for all inpatient encounters from 40 U.

The new pediatric radiologist.

This article discusses challenges in becoming a pediatric radiologist and contains words of advice from two young pediatric radiologists. Discussions include fellowship challenges and adjustment to being a new attending, including balancing work and life and difficult cases.

Factors influencing subspecialty choice among radiology residents: a case study of pediatric radiology.

Purpose: Persistent workforce shortages exist in some radiology subspecialties. Residents' motivations for selecting particular fellowships, as well as their perceptions of the subspecialty fields, heavily influence the supply of new radiologists to these areas. The authors investigated the factors residents consider most important in subspecialty choice, fellowship choice patterns between 1999 and 2008, and changes that might attract residents to one particular shortage field: pediatric radiology.

Bonding of stainless steel brackets to enamel with a new self-etching primer.

The purpose of this study was to measure the shear bond strength of stainless steel brackets bonded to enamel in vitro with a recently developed self-etching primer (Transbond Plus Self Etching Primer, 3M Unitek, Monrovia, Calif). Forty-eight extracted human teeth were obtained and randomly divided into 4 groups of 12: (1) control group with a conventional etchant and separate primer, (2) experimental group with the self-etching primer, left for 15 seconds before bonding, (3) same as group 2, but with the primer left for 2 minutes before bonding, (4) same as group 2, but with the primer left for 10 minutes before bonding. For each group, stainless steel brackets were mounted onto the prepared enamel, stored for 24 hours at 37 degrees C, and tested in a testing machine with a crosshead speed of 1 mm/min.
