“…In this study, microscopy showed very high sensitivity (90%), implying that wet-mount preparations are cost-effective, easy to use, and the fastest way to prove fungal elements (conidia and hyphal forms) in patient’s material. The higher sensitivity of microscopy recorded in our study, compared to the results of other authors, can be explained by the fact that they referred to the sensitivity of this method in otomycoses caused by yeast and molds, but here we focused only on Aspergillus -otomycoses [ 7 ]. As for the cultivation process, we can highlight that 83.3% of molds grew at both incubation temperatures, and five samples ( A. niger complex) required a temperature of 27–28 °C.…”

“…The diagnosis of otomycosis is less often followed by laboratory analyses, which may include microscopy and cultivation. Cultivation is the only method that allows for the identification of fungi and is considered to be the gold standard [ 7 , 8 ]. Patients with a non-invasive form of infection are treated with extensive debridement of the ear canal, followed by the regular application of topical antifungal drugs.…”

Species of Aspergillus (A.) niger complex and A. flavus complex are predominant molds that are causative agents of otomycoses. The goal of this study was to investigate the clinical presentation, diagnostic procedure, and appearance of relapse in patients with Aspergillus-otomycosis, as well as to determine the biofilm production ability of species isolated in relapse. Thirty patients with laboratory evidenced Aspergillus-otomycosis followed by two check-ups (30 and 60 days after initiation of treatment with antimycotics for local application) were included in the study. For isolation and identification of Aspergillus spp. the standard mycological procedure was applied. Results showed very high sensitivity of microscopy, but 16.7% Aspergillus species required the optimal temperature of 27–28 °C for cultivation. Applied statistical cluster analysis showed a defined specific cluster/group of patients with A. niger complex-otomycosis. Sixty days after diagnosis and treatment initiation, six patients had a relapse, with the same species of Aspergillus genus being the cause. To establish the ability of biofilm production, the modified method described by Pierce and Kvasničková was performed, and all six species isolated in the relapse episode had the ability to produce biofilm. Official criteria and recommendations are needed due to the possibility of misdiagnosis, which leads to the prolongation and complication of the disease.

“…As previously reported, 1 and 2 kHz are important for understanding speech signals, and frequency importance functions are very high. 10 Therefore, amplification of medium frequency is essential in the measurement of MCL. In this view, VSB is an ideal option to achieve better MCL values in a general communication situation.…”

“…Otomycosis is a common inflammatory lesion in otolaryngology that accounts for 10%–20% of ear canal infections ( 2 ). Otomycosis is very common in tropical and subtropical regions where the temperature and humidity are high ( 3 ). Frequent ear picking ( 4 ), chronic otitis media ( 5 ), and the use of antibiotics ( 6 ) all increase the incidence of otomycosis.…”

Otomycosis is caused by fungi, which usually cause discharge and additional discomfort. The highest incidence of otomycosis occurs in summer. To better treat this disease, it is necessary to study the microbial diversity of otomycosis secretions. In this regard, this study used high-throughput sequencing technology to determine the microbial diversity of the ear canal secretions of six typical patients with otomycosis in Wuhan via internal transcribed spacer (ITS) and 16S rRNA analyses and proposed a reasonable clinical treatment plan. Six patients with otomycosis in the Department of Otorhinolaryngology, Hubei Third People's Hospital Affiliated with Jianghan University, were selected from June 2022 to August 2022. The results showed that Staphylococcus spp. (average abundance 29.05%) was the dominant bacteria and Aspergillus spp. (average abundance 90.68%) was the dominant fungus involved in otomycosis secretion. Aspergillus spp. can cause inflammation of the external auditory canal combined with bacterial infections such as Staphylococcus spp., which can cause discharge in the ear canal. High-throughput sequencing provides comprehensive information on the microbial community involved in otomycosis discharge and will aid in evaluating the efficacy of clinical treatment and medication.

Otomycosis in immunocompetent patients: Clinical and mycological features. Our experience with 40 cases

Abstract: | CONCLUSIONWith respect to loudness level, MCL was more normalised using VSB than HA. Patients with moderate and moderate-tosevere SNHL could tolerate VSB fitting with sufficient amplification at 1 and 2 kHz frequencies, which is critical for normalising MCL.
