This report describes methods to estimate fetal radiation doses from radiation diagnostic examinations, based on survey data from 3 hospitals in southern Sweden. The fetal dose has been calculated with available computer programs and verified by dose measurements inside a female human phantom for conventional X-ray and computed tomography (CT) examinations. Measured fetal doses have been correl...

BACKGROUND Pediatric catheterization exposes patients to varying radiation doses. Concerns over the effects of X-ray radiation dose on the patient population have increased in recent years. This study aims at quantifying the patient radiation dose reduction after the introduction of an X-ray imaging technology using advanced real time image noise reduction algorithms and optimized acquisition c...

Background. Transseptal puncture (TSP) can be challenging. We compared safety and efficacy of a modified TSP technique ("mosquito" technique, MOSQ-TSP) to conventional TSP (CONV-TSP). Method. Patients undergoing AF ablation in whom first attempt of TSP did not result in left atrial (LA) pressure (failure to cross, FTC) were randomized to MOSQ-TSP (i.e., puncture of the fossa via a wafer-thin in...

OBJECTIVES The authors sought to compare the radiation dose between radial and femoral access. BACKGROUND Small trials have shown an increase in the radiation dose with radial compared with femoral access, but many were performed during the operators' learning curve of radial access. METHODS Patients were randomized to radial or femoral access, as a part of the RIVAL (RadIal Vs. femorAL) tr...

Dichloro-1,2-diaminocyclohexane (DACH):platinum(II), the prototype DACH:platinum complex, had good antitumor activity, was not cross-resistant with cis-dichlorodiammineplatinum(II) (DDP), but was, unfortunately, virtually insoluble in water and was, therefore, not evaluated clinically. This paper summarizes some of the chemical and biological attributes of a series of cis-bisascorbato-DACH:plat...

Objective The endovascular repair of aortic abdominal aneurysms exposes the patients and surgical team to ionizing radiation with risk of direct tissue damage and induction of gene mutation. This study aims to describe our standard of radiation exposure in endovascular aortic aneurysm repair and the factors that influence it. Methods Retrospective analysis of a prospective database of patient...

conclusions the effective annual dose of interventionists who work in center 1 and 2 was 143.08 and 1226.78 msv respectively. the high radiation dose which delivers to the leg of physicians in center 2 can be an important cause of radiation dermatitis occurred on the leg of our interventionist. patient dose during most of the procedures was less than the threshold dose for occurring erythema bu...

Background: Many clinical trials have demonstrated the benefit of trans-radial access (TRA) over trans-femoral (TFA) in reducing mortality and bleeding events, but there is some concern about radiation exposure with radial access. Objective: To assess difference between femoral approach as measured by dose-area product (DAP) fluoroscopy time. Methods: This cross-sectional study was performed pa...

Despite the technological advance in 3-dimensional (3D) mapping, radiation exposure during catheter ablation of atrial fibrillation (AF) continues to be a major concern in both patients and physicians. Previous studies reported substantial radiation exposure (7369-8690 cGy cm) during AF catheter ablation with fluoroscopic settings of 7.5 frames per second (FPS) under 3D mapping system guidance....

High-dose daptomycin (DAP) therapy failed in a neutropenic patient with bloodstream infection caused by a DAP-susceptible Enterococcus faecium (minimum inhibitory concentration, 3 µg/mL) harboring genetic changes associated with DAP resistance, with persistent bacteremia and selection of additional resistances. Daptomycin monotherapy should be used cautiously against DAP-susceptible E. faecium ...
