Anecdotal reports are appearing in the scientific literature about cases of brain tumors in interventional physicians who are exposed to ionizing radiation. In response to this alarm, several designs of leaded caps have been made commercially available. However, the results reported on their efficacy are discordant.

We report the first case of Lactococcus garvieae infection in Chile, presenting as an infective endocarditis, ultimately fatal, in a patient with uncomplicated colonic diverticulosis and end stage renal failure undergoing chronic hemodialysis. We review the published cases and discuss the diagnostic and therapeutic challenges associated with this new, increasingly diagnosed pathogen, capable of producing serious infections in susceptible patients.
View Article and Find Full Text PDFBackground: The effectiveness against radiation of tungsten bismuth caps, used in interventional cardiology is not well known.
Aim: To determine the degree of radiation protection conferred by these caps in real work conditions.
Material And Methods: We compared the gross electric charges received at brain lobe levels by three occupationally exposed professionals who participated in 22 consecutive procedures, inside and outside of the tungsten bismuth cap.
Background: It is not known whether leaded glass goggles with 0.25 mm Pb equivalency, used in interventional cardiology procedures, attenuate radiation below the levels established by the latest recommendation of the International Commission on Radiological Protection (ICRP).
Aim: To assess if the degree of attenuation of the secondary ionizing radiation achieved by the use of 0.
