In the extrusion of aluminum alloys, skin contamination lead to scraping profile extent in which this defect occurs. order optimize process, companies and die makers can either perform time-consuming expensive analyses experimentally determine evolution or rely on predictive methods. Recently, numerical methods, as Finite Elements, are increasingly used predict contamination, but their accuracy...

BACKGROUND This study investigated on bacterial contamination of the rhinoplasty field. The effect of preoperative chlorhexidine treatment on decreasing bacterial contamination in the rhinoplasty field is examined. METHODS Thirty patients who underwent rhinoplasty were block randomized into a chlorhexidine, regular-soap, or control group comprising ten participants each. The chlorhexidine gro...

Methods Following a standardized physical exam using sterile gloves and a sterile stethoscope, bacterial contamination of the following regions were assessed using contact plates: stethoscope diaphragm, stethoscope tube, fingertips, thenar region, hypothenar region and back of physician’s dominant hand. Total aerobic colony count (ACC) were determined on digital photographs using a counting tool.

INTRODUCTION Food-borne infections and intoxications remain one of the most important public health issues globally, both in developing and in developed countries. Numbers of reported outbreaks of food-borne diseases and diseased people are constantly growing. For instance, a total of 320,000 of cases of food-borne diseases, caused by only 6 most prevalent bacterial pathogens (non-typhoidal Sal...

Myco. fortuitum was isolated from subcutaneous abscesses of two patients who had been inoculated with B.C.G. and one patient who had iron injections. The organisms were resistant to a wide range of anti-tuberculous drugs. They were highly virulent for mice in which they produced symptoms of spinning disease. It is thought that the infections originated from contamination of syringes or skin.

or breaks in the skin. Hispanic Americans may be more likely to reside in agrarian settings with increased exposure to soil and opportunities for contamination of cuts and other injuries. Whether caused by environmental factors, genetic predisposition, access to medical care, or other socioeconomic factors and pressures, the reasons for the higher incidence of BAE in Hispanic Americans warrant ...

Tattoos are well known to cause skin problems and the number of reported adverse reactions after tattooing has increased. Illegally imported tattoo ink is unrestrained and can contain unknown ingredients and contamination thereby posing a serious health hazard. We present a case illustrating the risk of pronounced phototoxic allergic reaction and other severe complications after using home kit ...

Gloving reduces acquisition of vancomycin-resistant Enterococcus species (VRE) on the hands, and it should be considered for routine inpatient care, even for contact with the intact skin of patients who may be colonized with VRE. However, gloving does not completely prevent contamination of the hands, and hand washing is necessary after glove removal.

  Introduction: Several studies have discussed to the electron contamination caused by the air column between the head of linac and patient for photon beams. Since it is not possible to measure the electron contamination with practical dosimetry, the Monte Carlo technique is an appropriate and accurate choice to calculate particle flounce in radiation therapy. The purpose of t...
