Objective: To describe the use of a laryngophone to aid in verbal communication when wearing elastomeric respirator masks. Methods: Design: Instrumentation Innovation. Setting: Tertiary Private Training Hospital. Participants: Five volunteers using elastomeric respirator masks rated laryngophone use, afterwhich they individually rated an additional volunteer on speech intelligibility before and after laryngophone use. Results: On a scale of 1-10, the average score of the five volunteers for the laryngophone was 8.8 for ease of use, 8.0 for comfort, and 8.0 for ease of communication. Their average speech intelligibility score for the additional volunteer using the respirator mask alone was 2.0, and for use of the respirator mask with laryngophone was 3.6 on a scale of 1-4. Conclusion This portable laryngophone speaker may be useful in aiding otolaryngologists and health care providers using elastomeric respirator masks in verbal communication by amplifying speech without needing an external microphone, preventing vocal strain.

Objective: To test the antibacterial properties of three commercially available nasal corticosteroid preparations containing Mometasone Furoate (MF), Fluticasone Propionate (FP) and Fluticasone Furoate (FF) against S. pneumoniae, S. viridans, S. aureus, H. influenza, P. aeruginosa and E. coli. Methods: Study Design: Experimental in vitro study using the disc diffusion method. Clinical isolates of Streptococcus pneumoniae, Hemophilus influenzae, Streptococcus viridans, Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli were inoculated on separate plates. 0.15 ml of nasal corticosteroid preparations containing MF, FP and FF were applied to blank paper discs, then placed on the plates, including an empty disc. Following 24 and 48 hours of incubation, the inhibition zones were measured to the nearest mm from the point of abrupt inhibition of growth. Results: After 24 and 48 hours of incubation, S. pneumoniae, S. viridans, and S. aureus showed inhibition zones to all three preparations. S. aureus and S. viridans show the largest zones of inhibition at 24 and 48 hours respectively. H. influenza, P. aeruginosa and E. coli were negative. The inhibition zones of each bacteria were shown to be statistically different. The preparation containing FP had the largest zone of inhibition at 24 and 48 hours, although post hoc tests showed their difference was not significant. Conclusion: The present study demonstrates possible antimicrobial properties of commercially available nasal corticosteroid preparations. However, it is unclear whether these can be attributed to the steroids, their excipients, or both. Further studies testing each component may offer better insights into their therapeutic use.
