Abstract
For preoperative skin antisepsis, alcohol-containing iodine solutions and octenidine are suitable. For wound antisepsis, polyhexanide and hypochlorous acid (HOCL) are also available, but only PVP-iodine and HOCL can be applied to cartilage. Chlorhexidine should only be used as mouth- and bodywash for Staphylococcus aureus (MRSA) decolonization. For the many other throat antiseptics, evidence of clinical efficacy is lacking. For decolonization of the nares, polyhexanide and octenidine are available as nasal gels, but these are inferior to mupirocin for MRSA decolonization. PVP-iodine and HOCL are safe to use for nasal irrigation, but only HOCL has proven effective to improve symptoms of chronic rhinosinusitis. All antiseptics exhibit a certain ototoxicity. With an intact eardrum, acetic acid-containing eardrops can be used to prevent and treat external otitis and myringitis. When the eardrum is perforated, only alcohol-free PVP-iodine and HOCL may be used.

Otomycosis: The foremost aetiological agent causing otitis externa and the antifungal susceptibility pattern in North-Western Iran. Mycoses 2023; 66:87-97. [PMID: 36134511 DOI: 10.1111/myc.13532] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 09/01/2022] [Accepted: 09/15/2022] [Indexed: 01/12/2023]
Abstract
BACKGROUND Otomycosis is considered a recurring fungal ear infection. The external auditory canal provides an appropriate and optimal situation for fungal growth. OBJECTIVES The study aimed to identify the causative agents of otomycosis and determine corresponding antifungal drug susceptibility patterns in north-western Iran. METHODS From October 2020 until November 2021, 200 patients attended an otolaryngology referral centre with otitis externa, and their ear discharge and debris were examined and cultured. The identification of the fungal agents was implemented by polymerase chain reaction-restriction fragment length polymorphism and sequencing. In vitro antifungal susceptibility testing of the isolates was conducted in accordance with the CLSI broth microdilution protocols. RESULTS The prevalence of otomycosis was measured 50.5% (n = 101/200). The majority of patients were in their forties (n = 35, 34.6%) and female (n = 57, 56.4%), and the most prevalent symptom was otalgia (56.4%). The most underlying factor was remarked manipulation employing a cotton swab (65.3%). Regarding fungus, Aspergillus section Nigri (58.57%) was the foremost isolate, followed by Aspergillus section Flavi (19.23%) and Candida parapsilosis (14.96%). The predominance of Aspergillus isolates had minimal in vitro sensitivity to tioconazole and nystatin. Candida species represented higher geometric mean minimum inhibitory concentrations (MIC) against nystatin. The MIC of three Aspergillus species isolates shown above the epidemiologic cut-off values (ECV) against itraconazole. CONCLUSIONS Otomycosis incidence surpassed in comparison with the previous study as the most common cause of otitis externa. The MIC distribution of Aspergillus species isolates against triazole antifungals is close to the defined ECVs and likely outrun it over time.
