We present first results from the third GRavitational lEnsing Accuracy Testing (GREAT3) challenge, the third in a sequence of challenges for testing methods of inferring weak gravitational lensing shear distortions from simulated galaxy images. GREAT3 was divided into experiments to test three specific questions, and included simulated spaceand ground-based(More)
GALSIM is a collaborative, open-source project aimed at providing an image simulation tool of enduring benefit to the astronomical community. It provides a software library for generating images of astronomical objects such as stars and galaxies in a variety of ways, efficiently handling image transformations and operations such as convolution and rendering(More)
With the use of endovascular techniques and indwelling catheters, potential complications can include embolization of fragments or components of various systems. The authors describe the surgical retrieval of a guidewire introducer from the right common carotid artery (CCA). A 64-year-old man was found to have a foreign body within the right CCA on CT(More)
BACKGROUND There are very few reports in the literature of Castleman's disease affecting the carotid artery and a single previous report of a case of Castleman's disease of the neck originally mistaken as a carotid body tumor. CASE DESCRIPTION We describe a rare case of Castleman's disease, manifesting with classic radiographic hallmarks of a carotid body(More)
OBJECTIVE The authors describe a modified technique for placement of the C1 lateral mass screw using a Steinmann pin as a guide. This technique minimizes dissection and provides atlantoaxial stabilization during arthrodesis. METHODS In our technique, a nonthreaded 1.6-mm spade-tip Steinmann pin is placed into the lateral mass of C1 to serve as a guide(More)
STUDY DESIGN Retrospective cohort study. OBJECTIVE To identify trends in spinal procedure reimbursement in our practice since 2010. SUMMARY OF BACKGROUND DATA In an uncertain healthcare climate with continuous reform, trends in physician reimbursement are unclear. Market forces of supply and demand, legislation imposing penalties for quality measures,(More)
The role that the secondary gain of work-related back pain plays in the length of disability is an issue that has been debated for years without absolute resolution. This article compares the disability period of lumbar sprain/strain and operated back cases in employees injured on duty and off duty. The patients injured on duty had a statistically(More)
