In this chapter methods for growing and analyzing biofilms under hydrodynamic conditions in flow cells are described. Use of flow cells allows for direct microscopic investigation of biofilm formation. The flow in these chambers is essentially laminar, which means that the biofilms can be grown under highly controlled conditions, and that perturbations such as addition of antibiotics or change ...
To the Editor: We recently investigated a case of Mycobacterium chelonae abdominal wound infection after liposuction performed under local anesthesia at an outpatient medical office. Our aim was to determine whether other cases of atypical mycobaterial infections had previously occurred after liposuction. M. chelonae is widely distributed in soil and water, including tap water. Atypical mycobac...
Conventional photocatalysts are primarily stimulated using ultraviolet (UV) light to elicit reactive oxygen species and have wide applications in environmental and energy fields, including self-cleaning surfaces and sterilization. Because UV illumination is hazardous to humans, visible light-responsive photocatalysts (VLRPs) were discovered and are now applied to increase photocatalysis. Howeve...
Materials and methods: A total of 68 molar bands were tried-in mouth of 17 patients. After try-in, 60 bands were cleaned in ultrasonic cleaning bath and then were equally divided into two groups (n = 30). Bands from group 1 were autoclaved in benchtop autoclave. Bands from group 2 were sterilized in glass bead sterilizer. After sterilization, the bands from both the groups were incubated in 50 ...
The term 'ultrapure water' is a common way to define water used for on-line treatments: it refers to the absence of chemical, organic and microbiological contamination. To be more accurate in definition, every known and potential contaminant has to be fixed at its limit value. AAMI recommendations and various Pharmacopoeias have set limits for dialysate based on traditional dialysis treatments,...
PURPOSE The aim of this study is to consider the effectiveness of a small sample of dishwashers (DW) compared to washer-disinfectors (WD) for cleaning dental instruments prior to sterilisation. Processing instruments in the context of this article means cleaning and disinfecting the instruments. MATERIALS AND METHODS A number of tests were carried out on three domestic dishwashers and two ins...
Indicator cotton swabs have been developed in order to enable faster, less expensive, and simpler information gathering of a wound status. Swabs are normally used for cleaning the wound, but here, they were covalently functionalized with indicator chemistry. Thus, they in principle enable simultaneous wound cleaning and wound pH detection. Using an indicator dye with a color change from yellow ...
BACKGROUND Efficiency in the operating room has become a topic of great interest. This study aimed to quantify the percent use of instruments among common instrument trays across 4 busy surgical services: Otolaryngology, Plastic Surgery, Bariatric Surgery, and Neurosurgery. We further aimed to calculate the costs associated with tray and instrument sterilization, as well as the implications of ...
Reduction of the initial bioburden on instruments, prior to sterilization, is believed to reduce transmission risks of iatrogenic Creutzfeldt-Jakob disease. Endodontic files are used in the preparation of root canals and are likely to have close contact and become contaminated with neural material from branches of the maxillary and mandibular cranial nerves. This study examined methods used by ...
