All invasive procedures involve contact by a medical device or surgical instrument with a patient's sterile tissue or mucous membranes. The level of disinfection or sterilization is dependent on the intended use of the object: critical (items that contact sterile tissue such as surgical instruments), semicritical (items that contact mucous membrane such as endoscopes), and noncritical (devices ...

BACKGROUND AND AIMS We have previously reported a reduction in risk of diarrhoeal disease in children who used solar disinfected drinking water. A cholera epidemic, occurring in an area of Kenya in which a controlled trial of solar disinfection and diarrhoeal disease in children aged under 6 had recently finished, offered an opportunity to examine the protection offered by solar disinfection ag...

Contemporary endodontics and the future of endodontics are based on regenerative strategies. Success of these regenerative endodontic treatments depends on disinfection of the root canal system. Current research in endodontics focuses on identifying the optimal methods of disinfection of root canal systems to achieve predictable results in revascularization therapy. Although the use of sodium h...

Antiseptic preparations used repeatedly to disinfect the skin caused a reduction in yield of resident flora to a low equilibrium level beyond which further reduction did not occur. This equilibrium varied with the antiseptic preparation used. In a comparison of three preparations, the lowest equilibrium level was obtained with 95% ethyl alcohol. The further reduction in yield of skin bacteria o...

Introduction: Health-care waste can threaten the health of humans and environment due to dangerous, toxic and pathogenic agents. This study was conducted to investigate the status of disinfection equipment in Tehran hospitals as well as their health and economic evaluation in 2016. Materials and Methods: In this research, 27 hospitals in Tehran that equipped with disinfection equipment were se...

Background: Laboratory personnel is at risk of biological contamination leading to laboratory-acquired infections (LAIs). The use disinfection products essential in the prevention these infections. This work aimed evaluate effectiveness antimicrobial agents used bacteriology laboratories Togo. Methods: was a cross-sectional study conducted from June December 2021 all Swabs taken before and afte...

BACKGROUND The Rudolf Schuelke Foundation addresses topics related to hygiene, infection prevention and public health. In this context a panel of scientists from various European countries discussed "The Role of Surface Disinfection in Infection Prevention". The most important findings and conclusions of this meeting are summarised in the present consensus paper. AIM Although the relevance of...

INTRODUCTION To evaluate the cause of methemoglobinemia in patients undergoing extended daily hemodialysis/hemodiafiltration we analyzed the relationship between methemoglobinemia and the water disinfection schedule of the hospital. METHODS We reviewed all arterial blood gas analyses, obtained over a one-year period, in patients undergoing extended hemodialysis/hemodiafiltration, and compared...

Titania (TiO2) induced photocatalysis has been widely investigated and applied as a disinfection strategy in many industrial and clinical applications. Reactive oxygen species (ROS), including hydroxyl radicals (•OH), superoxide radicals ( − •2 O ) and hydrogen peroxide (H2O2), generated in the photocatalytic reaction process are considered to be the active components prompting the bactericidal...

PURPOSE To assess the disinfection efficacy of multipurpose solutions (MPS) against different bacterial species adhered either to silicon hydrogel or to conventional hydrogel contact lenses (CLs). The influences of the MPS formulation and the chemical composition of the lens material were investigated. METHODS This investigation followed the standard 14729, which establishes the guidelines fo...
