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.

background and purpose: hand contamination is an important factor of infection transmission from dental staff to patients and vice versa. the aim of this study was to determine the effect of hand washing training on dental students’ knowledge, attitude, and clinical practice at the shahid beheshti university of medical sciences dental school in 2010. methods: this quasi-experimental study was c...

The objective of this study was to determine bacterial contamination of the hands in a group of medical trainee students attending practical training, in order to verify the reliability of the information on hand hygiene (HH) adherence obtained by a self-reporting questionnaire. The study questionnaire was designed with the purpose of investigating the effectiveness of basic health education an...

We determined risk factors for hand contamination and compared the efficacy of 3 randomly allocated hand hygiene agents in a group of surgical intensive care unit nurses. We cultured samples of one of the subjects' hands before and samples of the other hand after hand hygiene was performed. Ring wearing was associated with 10-fold higher median skin organism counts; contamination with Staphyloc...

BACKGROUND An ideal computer keyboard for clinical use would be easily cleanable and cleaned by staff, meet acceptable levels of usability, and not attract hospital bacteria. METHODS In vitro studies were performed to demonstrate bacterial transfer between keyboard surfaces and gloves. This was followed by a usability study and a controlled trial of keyboard contamination in an intensive care...

The microbiologic contamination can occur in all the steps of an intraoral conventional or digital radiographic examination, unless some measures to avoid the cross-infection are applied. Scientific articles have shown that during the radiograph taking procedure, there is contact with the patient’s oral fluids (saliva and blood) and, consequently, the contamination of the film or digital sensor...
