OBJECTIVE:
To investigate the situation regarding the cleaning and sterilization of endonasal endoscopes in department of otolaryngology in Hunan Province, and to provide strategy for improving the level of sterilization and management of endonasal endoscopes.
METHODS:
A total of 100 medical institutions were investigated by spot assessment, check and sampling. Data was analyzed by multivariate analysis.
RESULTS:
The qualified rate of rules and regulations for endoscopy was 28.8% in the second-class hospitals and 45% in the top-class hospitals. The qualified rate of environment for endoscopy cleaning and sterilization was 36.3% in the second-class hospitals and 85% in the top-class hospitals. The main problems include lack of independent disinfection room, the space not large enough, and/or lack of ventilation system. The qualified rate of bacterial detection for post-sterilized endoscopes and biopsy forceps was 93.8% in the second-class hospitals and 95.0% in the top-class hospitals, and the main pathogenic bacteria was gram-positive cocci and gram-negative bacilli. The multivariate analysis showed that the influencial factors for endoscope cleaning and disinfection are as follows: staffs responsible for the cleaning and sterilization of otolaryngology endoscopes, the standard for cleaning and disinfection process, and the frequency of endoscope use.
CONCLUSION
The present situation of cleaning and sterilization for otolaryngology endoscopes is better in the top-class hospitals than that in the second-class hospitals. The sterilization and management of otolaryngology endoscopy are needed to be improved, and the staff training is needed, especially in the primary hospitals.

To understand the potential causes of laboratory-acquired infections and to provide possible solutions that would protect laboratory personnel, samples from a viral laboratory were screened to determine the main sources of contamination with six subtypes of Rhinovirus. Rhinovirus contamination was found in the gloves, cuffs of protective wear, inner surface of biological safety cabinet (BSC) windows, and trash handles. Remarkably, high contamination was found on the inner walls of the centrifuge and the inner surface of centrifuge tube casing in the rotor. Spilling infectious medium on the surface of centrifuge tubes was found to contribute to contamination of centrifuge surfaces. Exposure to sodium hypochlorite containing no less than 0.2 g/L available chlorine decontaminated the surface of the centrifuge tubes from Rhinovirus after 2 min.

PURPOSE: Glass particle contamination of the contents of single-dose glass ampules can occur upon opening. Different aspiration techniques, different sizes of needles, different sizes of ampules, and different cutting methods were studied to determine if they had any effect on glass particle contamination. METHOD: Different aspiration techniques(with filter, without filter), different sizes of needles(18G, 25G), different sizes of ampules(2ml, 20ml), and different cutting methods(with cotton, without cotton) were evaluated. METHOD: Twenty ampules were randomly assigned in each group. Three slides containing glass particles for each ampule were made and counted under a microscope by 3 study blind persons. RESULT: The number of glass particle contamination is much less when using a filter rather than without a filter. The number of glass particle contamination is much less when using a 25G needle rather than on 18G needle. The number of glass particle contamination is much less when using 2ml ampules rather than 20ml ampules. The number of glass particle contamination is much less when using cotton rather than without cotton. CONCLUSION: It was shown that using a filter, a small size needle, smaller sized ampules and using cotton when cutting the ampule will decrease the risk of parenteral injection of glass particles.

Gordonia sputi causes rare bacterial infections resulting from a contaminated indwelling medical device. We report the case of a postoperative plastic expander abscess in a woman, with G. sputi identification by 16S ribosomal RNA sequencing. This report indicates that Gordonia spp. should be included in the list of organisms causing plastic implant infections.
