Prevention of Nosocomial Infection During Dermoscopy?

Abstract

Alcohol-based antibacterial gel appears to inhibit bacterial colonization while offering excellent optical resolution during dermoscopic examination. The use of alcohol-based IF appears to obviate the risk of nosocomial infections.

Evaluation of dermoscopy in the diagnosis of naturally occurring dermatophytosis in cats

“…Hairs were plucked using mosquito haemostats and inoculated onto enhanced Sabouraud's Dextrose Agar and dermatophyte test medium (DTM) containing phenol red (pH indicator), antibiotics (gentamicin, chlortetracycline) and cycloheximide (Shelby Scientific; Macomb, MI, USA) . Haemostats were disinfected with accelerated hydrogen peroxide 0.5% (Accel ® TB) and antibacterial gel 62% ethyl alcohol (Purell ® ) after each use and between each animal to prevent contamination . The haemostats were wiped dry with a paper towel between each disinfectant.…”

Entodermoscopy: A New Tool for Diagnosing Skin Infections and Infestations

“…The latter appear as irregularly distributed, small, red to black to brown tiny dots or streaks (fig. 1b) [1,2,3,4,5,6,7,8,9,10,11,12,13,14]. These features are helpful to reassure an eventually clinical doubtful diagnosis, for example in cases of irritated or subungual/periungual warts.…”

“…Many newer devices use cross-polarized light to visualize cutaneous structures, and as such do not require direct physical contact between the optical lens and the skin. In this way, they can be employed without the risk of possible transfection, although this risk is generally considered low even with traditional oil-immersion (contact) dermatoscopes [7,8,9]. The factors listed above may explain why dermoscopy, apart from its classical application for the diagnosis of skin tumors, has also recently become popular for the in-vivo diagnosis of infectious skin conditions [10].…”

The role of various immersion liquids at digital dermoscopy in structural analysis

“…Additionally, Kelly et al reported that alcohol-based gel presented the same quality of image definition with immersion oil. [16] In the identification of pigment network, which is an important parameter for the diagnosis of melanocytic lesions, immersion oil was observed to be more appropriate than ultrasound gel. In the identification of structural components other than the pigment network, it was observed that the images obtained with ultrasound gel or immersion oil were not different from each other.…”
