OBJECTIVE: The present study evaluates the dose distribution received by physicians involved in hemodynamic procedures of coronary angiography and coronariography. The influence of some factors such as pulsed or continuous fluoroscopy mode and vein and/or artery access site was investigated. MATERIALS AND METHODS: Measurements have been performed with LiF:Mg,Ti thermoluminescent dosimeters plac...

The transfer of gram-positive bacteria, particularly multiresistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE), among patients is a growing concern. One critical aspect of bacterial transfer is the ability of the microorganism to survive on various common hospital surfaces. The purpose of this study was to determine the survival of 22 gram-positive bacteria (vancomy...

[1] The evolution of the Martian crustal dichotomy boundary, which separates the southern cratered highlands from the northern lowland plains by 1–3 km of elevation, remains among the fundamental outstanding issues in Mars research. For a study area at Aeolis Mensae we show that fretted terrain formed exclusively in a >2 km thick, late Noachian ( 3.7 Ga) sedimentary deposit that overlies the ba...

Data have been collected and physical and statistical models have been constructed to estimate unknown occupational radiation doses among 90,000 members of the U.S. Radiologic Technologists cohort who responded to a baseline questionnaire during the mid-1980s. Since the availability of radiation dose data differed by calendar period, different models were developed and applied for years worked ...

BACKGROUND Fluoroscopic guidance may be utilized in some bronchoscopic procedures, including ultrasound-guided bronchoscopy for investigation of peripheral pulmonary lesions. Some authors have suggested this procedure may be performed without fluoroscopy, to minimize risks due to radiation exposure. However, the radiation dose has never been quantified, so the risk remains unknown. OBJECTIVE ...

BACKGROUND Health system should be organized to meet the needs of entire population of the nation. This means that the state has the direct responsibility for the health of its population and improving the quality of life through research, education, and provision of health services. The present study was conducted to evaluate the government oral health care delivery system in Haryana, India. ...

Background.  The first case of Ebola diagnosed in the United States and subsequent cases among 2 healthcare workers caring for that patient highlighted the importance of hospital preparedness in caring for Ebola patients. Methods.  From October 21, 2014 to November 11, 2014, infectious disease physicians who are part of the Emerging Infections Network (EIN) were surveyed about current Ebola pre...

INTRODUCTION The aim of this study was to demonstrate the efficacy of Instadose™, a novel dosimeter designed for radiation workers to provide a measurement of the radiation dose at any time from any computer; to determine the amount of radiation exposure during percutaneous nephrolithotomy (PNL); and to evaluate the factors that affect the amount of radiation exposed. MATERIAL AND METHODS Two...

The widespread use of minimally invasive and other spinal procedures raises concern about the peroperative radiation exposure to surgeon and patient. The authors noted the fluoroscopy time and the radiation dose, as read from the image amplifier, in 95 spinal procedures. The results of this prospective study varied widely between different operations. Percutaneous surgery was associated with mo...

BACKGROUND/AIMS During endoscopic retrograde cholangiopancreatography (ERCP), all efforts should be made to be aware of radiation hazards and to reduce radiation exposure. The aim of this study was to investigate the status of radiation protective equipment and the awareness of radiation exposure in health care providers performing ERCP in Korean hospitals. METHODS A survey with a total of 42...
