AIM This study aims to determine the role of mixing techniques of polyether impression materials and efficacy of disinfection on microbial colonization of these impression materials. MATERIALS AND METHODS Polyether impression material was mixed using two methods: First by hand mixing (group I) and second using an automixer (group II) with a total of 100 samples. Four microbial strains were st...

UNLABELLED The standardized training of practical competences in skills labs is relatively new among German Medical Faculties. The broad acceptance and outstanding evaluation results do not provide objective data on the efficiency and cost-efficiency of these trainings. This study aims on the quantification of the teaching effect of the surgical scrubbing technique EN1500 and its comparison wit...

BACKGROUND Despite the increasing use of Alcohol-Based Hand Rub solutions, few studies have quantified the concentrations of inhaled ethanol. OBJECTIVE The aim of this study was to assess ethanol exposure during hygienic and surgical hand disinfection practices. METHOD Ethanol concentrations were measured at the nose level of a wooden dummy and human volunteers. Two systems were used in par...

Puerperal fever was common in mid-19(th)-century hospitals and often fatal, with mortality at 10%-35%.

Disinfection byproduct (DBP) precursors in wastewater during the reversed anaerobic-anoxic-oxic (A2/O) process, as well as their molecular weight (MW) and polarity-based fractions, were characterized with UV scanning, fluorescence excitation emission matrix, Fourier transform infrared and nuclear magnetic resonance spectroscopy. Their DBP formation potentials (DBPFPs) after chlorination were fu...

Hand hygiene is the most important measure to protect against the spread of nosocomial infections. With the development of in vitro und in vivo test methods for evaluation of the effect of hand hygiene, there has been a sharp increase over the past 50 years in the body of knowledge relating to effective methods for removal from the hands or killing and inactivation of pathogens. In 1958 the Ger...
