Survey of current status and physician opinion regarding ancillary staffing for the IR suite.

Purpose: To survey the status quo of ancillary staffing in predominantly hospital-based interventional radiology (IR) suites and to assess interventional radiologist attitudes toward current IR procedure room staffing availability and appropriateness.

Materials And Methods: Invitations to an online survey composed of 26 questions focused on levels of IR suite ancillary staffing as well as operators' opinions of current IR procedure room staffing were sent via email to 2,284 active Society of Interventional Radiology members.

Results: There were 777 survey responses.

Experimental dengue virus challenge of human subjects previously vaccinated with live attenuated tetravalent dengue vaccines.

Background: Protection against dengue requires immunity against all 4 serotypes of dengue virus (DENV). Experimental challenge may be useful in evaluating vaccine-induced immunity.

Methods: Ten subjects previously vaccinated with a live attenuated tetravalent dengue vaccine (TDV) and 4 DENV-naive control subjects were challenged by subcutaneous inoculation of either 10(3) plaque-forming units (PFU) of DENV-1 or 10(5) PFU of DENV-3.

Advances in vascular imaging.

Advances in vascular surgery have mirrored advances in diagnostic imaging. Indeed, the endovascular revolution has been made possible largely by advances in computed tomography, magnetic resonance imaging, and vascular ultrasound. As technology allows better noninvasive vascular diagnosis, conventional angiography, once the gold standard for the diagnosis of vascular disease, is now reserved largely for intervention.

Human immunodeficiency virus arteriopathy of the adult cerebral circulation.

Arteriopathy associated with human immunodeficiency virus infection and clinical acquired immunodeficiency syndrome is well-documented. The pathophysiology of this arteriopathy may vary in different vascular beds. Although arteriopathy of central nervous system (CNS) circulation has been recognized in pediatric patients since the late 1980s, there are no reported cases of CNS arteriopathy in adults.

Radiology in a hostile environment: experience in Afghanistan.

Imaging equipment deployed with the combat support hospital in Afghanistan represented new technology not previously used in a hostile environment for a prolonged period. In general, the equipment performed well in a stationary location. Having computed tomography and ultrasound scans, in addition to plain radiographs, was very helpful for patient care.

Totally percutaneous aortic aneurysm repair: experience and prudence.

Objective: Totally percutaneous aortic aneurysm repair has been shown to be technically feasible, with low morbidity. Complications from percutaneous arterial closure are not insignificant, however, and can be fatal. We sought to evaluate our experience with this technique, compare it with the published literature, and identify factors associated with conversion to open repair and complications.

Computed tomography of craniofacial trauma at a combat support hospital in Afghanistan.

Complex craniofacial injuries are encountered among both soldiers and civilians in combat zones. Computed tomography is a necessary and effective tool for the evaluation and treatment of these injuries in the forward-deployed combat support hospital.
