Background. "Lead hands" are frequently used to maintain hand and finger position in hand surgery. The malleability and strength of lead make it ideal for this purpose. The aim of this study was to determine the amount of lead transferred to a surgeon's glove during handling of a lead hand. Method. Sterile surgical gloves were wiped over the surface of a lead hand. The number of wipes was varie...

Carbon dioxide (CO2) is an established alternate angiographic contrast agent, which can be delivered by pump or hand injection. We describe a simple, safe and inexpensive hand injection system that delivers a known volume of CO2 at atmospheric pressure and prevents contamination with room air.

Quick and accurate detection of microbial contamination is accomplished by a unique combination of leading-edge technologies described in this and the accompanying paper. In this contribution, a hand-held prototype instrument is described which is capable of statistically sampling the environment for microbial contamination and determining cell viability. The technology is sensitive enough to d...

conclusions the study showed that elevator buttons could lead to transmission of pathogenic bacteria. it is necessary to clean and disinfect elevator buttons daily, especially in departments with high contamination potential such as laboratories, particularly in biological laboratories and pilot plant rooms. methods the study was a across sectional research. samples were taken from elevator but...

Abstract Compulsions are the hall mark of obsessive-compulsive disorder (OCD) but there has been surprisingly little research on their phenomenology and persistence, much this work focused checking compulsions. The current study examined hand wash duration in participants (N = 235) with high or normative contamination fear who either “contaminated” hands not, under vs. low responsibility/harm c...

The effects of interventions such as sanitation or hand hygiene on hand contamination are difficult to evaluate. We explored the ability of a simple microbiological test to: (1) detect recontamination after handwashing; (2) reflect risk factors for microbial contamination and (3) be applicable to large populations. The study was done in rural Andhra Pradesh, India, and Maputo, Mozambique. Parti...
