Etiology, Predisposing Factors, Clinical Features and Diagnostic Procedure of Otomycosis: A Literature Review.

Otomycosis (OM) is a superficial fungal infection of the external auditory canal (EAC) with a worldwide prevalence ranging from 9% to 30%. Commonly, otomycoses are caused by Aspergillus (A.) niger complex and Candida spp. Other causative agents are yeasts of the genera Cryptococcus spp., Rhodotorula spp., Geotrichum candidum, dermatophytes (Trichophyton mentagrophytes), and non-dermatophytes molds (Fusarium spp., Penicillium spp., Mucorales fungi). The widest range of different species causing OM are found in the territories of Iran, India, China, Egypt, Mexico, and Brazil. Fungal infection of the EAC varies from mild to severe forms. It can be acute, subacute, or chronic, and is often unilateral, while the bilateral form is more common in immunocompromised patients. From an epidemiological point of view, tropical and subtropical climates are the most significant risk factor for the development of otomycosis. Other predisposing conditions include clothing habits, EAC hygiene practices, long-term antibiotic therapy, diabetes, and immunodeficiency. Since it is often difficult to distinguish otomycosis from an infection of a different origin, laboratory-based evidence, including standard procedures (microscopy and cultivation), is essential for diagnosis. For the treatment of this superficial fungal infection, there are no official therapeutic guidelines and protocols. However, many antifungals for local application, such as polyene, imidazoles, and allylamines, can be applied, as well as systemic antimycotics (triazoles) in severe forms of infection.

Assessment of Life Quality in Children with Dysphonia Using Modified Pediatric Voice-Related Quality of Life Questionnaire in Serbia.

(1) Background: Hoarseness is not uncommon in children, especially at school age, as communication with peers is intensified. It is caused by improper use or overuse of the vocal apparatus. (2) Methods: The study included 85 hoarse children aged 6-12 (study group) and 240 healthy children (control group) of the same age. The study group underwent a detailed medical history, phoniatric examination, larynx fiber endoscopy, allergy treatment and the Pediatric Voice-Related Quality of Life questionnaire, modified by Jasmina Stojanovic. (3) Results: Our modified questionnaire revealed the significance of parental perception of a voice disorder in a child after organized activities. Using our modified questionnaire, we were able to determine the most frequent form of a voice disorder in children-speaking too loudly-is often neglected by the environment and can lead to an overall lower life quality. (4) Conclusions: As the presence of hoarseness impairs the quality of life in the pediatric population, awareness of a voice disorder must be recognized and treated on time to overcome the possible side effects on a child's psychological and emotional development.

Clinical Presentations, Cluster Analysis and Laboratory-Based Investigation of Aspergillus Otomycosis-A Single Center Experience.

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 Kvasnicková 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.

Impact of Sensorineural Hearing Loss during the Pandemic of COVID-19 on the Appearance of Depressive Symptoms, Anxiety and Stress.

BACKGROUND: The incidence of hearing loss is constantly increasing and according to the World Health Organization, by 2050, 900 million people will suffer from hearing loss. The main Objective of the study was to determine the differences between the severity of the symptoms of stress, anxiety and depression in participants with varying degrees of sensorineural hearing loss during the COVID-19 pandemic. An additional aim was to examine the extent and manner in which protective face masks impact the communication of people with hearing loss. Matrials and Methods: A cross-sectional study was conducted, which included 160 patients (81 men and 79 women) with bilateral sensorineural hearing loss. The patients' age range was 50 to 80 years. Depending on the degree of hearing loss or pure-tone threshold, the participants were divided into four groups: mild hearing loss, moderate hearing loss, severe hearing loss and profound hearing loss. The research used the Depression, Anxiety and Stress Scale (DASS-21) and a questionnaire in which the participants reported whether surgical face masks (medical three-layer masks) worn by speakers makes communication difficult, to what extent and in what way. RESULTS: The average age of the patients was 67.97 ± 8.16. A significant correlation was found between the degree of hearing loss and communication difficulties caused by the use of protective face masks (p < 0.001). For patients with severe and profound hearing loss, communication is significantly more difficult (50.0% and 45.0% respectively) when the interlocutor wears a face mask. There is a significant correlation between the degree of hearing loss and the way in which communication is made more difficult when the interlocutor wears a face mask (p < 0.001). A statistically significant difference was determined between the degrees of hearing loss in all measured subscales: stress (p = 0.024), anxiety (p = 0.026) and depression (p = 0.016). CONCLUSIONS: We have determined that face masks used during the COVID-19 pandemic significantly hamper communication among the study groups (p = 0.007) and there is a significant correlation between the degree of sensorineural hearing loss and the presence of symptoms in all three DASS-21 subscales, meaning that the symptoms of stress, anxiety and depression were more intense in severe and profound hearing loss.

[Correlation between histomorphometric changes and the type of aerobic bacteria isolated in chronic suppurative otitis media].

BACKGROUND/AIM: Bacterial flora is a very important factor in pathogenesis of chronic suppurative otitis media (CSOM) and significantly influences the type and intensity of osteolytic process. There are few histomorphometric investigations of middle ear mucosa in chronic otitis. The aim of this study was to identify aerobic bacteria responsible for chronic suppurative otitis media as well as their association with histomorphometric changes of middle ear mucosa. METHODS: A prospective study that comprised 153 patients treated in the Clinc for Ear, Thorat and Nose Diseases, Nis, was conducted. Bacteriologic analysis of diseased ear secretion was carried out in all patients. Intraoperatively removed granulation tissue was used for histomorphometry. The analysed parameters were: the number of inflammatory cells, as well as vascularization and vasodilatation. RESULTS: The most frequently isolated aerobic bacteria from chronic suppurative otitis media were Staphylococcus aureus (29.020/0), Pseudomonas aeruginosa (29.02%) and Proteus spp. (21.76%). There was no correlation between the type of pathologic process and the type of bacteria. The number of inflammatory cells in the granulation tissue in pure cultures of Staphylococcus aureus was 1,597.33 +/- 549.45 and in Pseudomonas aurzginosa cultures was 2639 +/- 648. CONCLUSION: This study showed that there is a statistically significant correlation between the number of inflammatory cells in the granulation tissue and the type of aerobic bacteria we isolated. The intensity of the infection in chronic suppurative otitis media depends on the type of the isolated bacteria, which emphasizes the importance of adequate preoperative antimicrobial therapy.

[Malignant tumors of auricula and periauricular area].

BACKGROUND/AIM: Malignant tumors of auricula and periauricular area represent seven percent of all cutaneous tumors. They appear mostly in the sixth and seventh decade. According to histological type they are basocellular and planocellular carcinomas. The most frequent etiology is the sun exposition. The aim of this study was to analyze clinical and histological characteristics and therapy of malignant tumors of auricular and periauricular area. METHODS: Totally 155 patients were treated in ORL Clinic, Clinical Center Nis during the period 1990-2006. The patients were treated surgically (59.35%), by radiotherapy (1.94%) and by combination of the two methods (38.71%). RESULTS: Since the majority of tumors were small and presented on the helix, wedge excision and primary reconstruction were performed (136), while total (9) or partial (10) auriculectomy were done in a small number of the patients. For larger lesions (T4--when lesion is greater than 4.0 cm) and neck metastasis invading cartilage or bone, parotidectomy (15), radical neck dissection (25) and temporal bone resection (9) were performed. CONCLUSION: Carcinoma of auricular and periauricular area should be confirmed by biopsy and histopathologic evaluation. In all cases an adequate excision, margin examination and observation of appropriate lymph node draining regions should be provided.
