ABSTRACT

Abstract Introduction: Otomycosis, an infection of the ear canal by fungi, is prevalent in hot and humid weather. Nevertheless, there is not sufficient evidence for the effectiveness of different topical antifungal treatments. Tolnaftate, is a topical antifungal agent described to be effective in the treatment of otomycosis. Currently there are not sufficient studies that prove its efficacy. Objectives: To compare the efficacy of clotrimazole and tolnaftate administration in the treatment of otomycosis. Material and methods: A controlled, randomized and open clinical trial included patients diagnosed with fungal external otitis who were treated with topical antifungals, randomized into two treatment groups: (1) clotrimazole cream; (2) tolnaftate solution. They were microscopically evaluated at one and two weeks of treatment to determine resolution of disease. Recurrence and complications were recorded. Demographic and clinical variables were collected and analyzed. Follow-up and final outcomes (absence of infection) were compared between groups. Results: Forty eight patients were included, 28 in the clotrimazole group and 20 in the tolnaftate group. Spring was the weather most commonly associated with otomycosis, while otic manipulation was the risk factor more common in both groups. Predominant symptoms were itching and otic fullness. Aspergillus niger organism was isolated most frequently. Treatment with clotrimazole resulted in 75% resolution vs 45% resolution with treatment with tolnaftate at one week of treatment (p = 0.007). The Tolnaftate treatment group demonstrated higher recurrence rates and treatment failures, 20% and 15% respectively. Conclusions: Clotrimazole cream treatment is more effective than tolnaftate for uncomplicated otomycosis. More studies are needed to corroborate our results.


Resumo Introdução: Otomicose, uma infecção fúngica do canal auditivo externo, é prevalente em climas quentes e úmidos. No entanto, a literatura não apresenta evidências suficientes sobre os diferentes tratamentos antifúngicos tópicos. O tolnaftato é um antifúngico tópico descrito como eficaz no tratamento da otomicose; entretanto, sua eficácia não está suficientemente comprovada. Objetivo: Comparar a eficácia do uso de clotrimazol e tolnaftato no tratamento da otomicose. Material e método: Ensaio clínico controlado e randomizado; incluiu pacientes diagnosticados com otite externa fúngica tratados com antifúngicos tópicos, randomizados em dois grupos de tratamento: 1) clotrimazole (creme); 2) solução de tolnaftato. Eles foram avaliados microscopicamente uma e duas semanas após o início do tratamento para avaliar a resolução da doença. Recorrência e intercorrências foram registradas; além disso, as variáveis demográficas e clínicas foram coletadas e analisadas. Os dados do acompanhamento e desfechos finais (ausência de infecção) foram comparados entre os grupos. Resultados: O estudo incluiu 48 pacientes, 28 dos quais foram alocados ao grupo clotrimazole e 20 ao grupo tolnaftato. A primavera foi a estação mais comum; a manipulação foi o fator de risco mais comum em ambos os grupos. Os sintomas mais comuns foram coceira e plenitude auricular. Aspergillus niger foi o micro-organismo mais comumente isolado. Após uma semana, o tratamento com clotrimazol apresentou uma taxa de resolução de 75% vs. 45% com o tratamento com tolnaftato (p = 0,007). O tratamento com tolnaftato apresentou maiores taxas de recidiva e falhas: 20% e 15%, respectivamente. Conclusões: Em casos de otomicose não complicada, o uso de clotrimazol (creme) é mais eficaz do que o de tolnaftato. Mais estudos são necessários para corroborar os presentes resultados.

ABSTRACT

Introduction: Otomycosis is a sub-acute or a chronic superficial fungal infection of the external auditory canal.It is one of the frequently encountered fungal infections of the ear. The prevalence of otomycosis is higher intropical and subtropical climates zones. This study was planned to identify the most common organismsinvolved in otomycosis, clinical features and various predisposing factors of the disease in south India.Materials and Methods: Prospective study on 187 confirmed cases of Otomycosis who attended the ENT OPD. Apredesigned proforma was administered to the participants to know the clinical symptoms, predisposingfactors, sociodemographic details, and comorbid conditions. Clinical findings in both ears were recorded.Results: The majority of the study population (31%) were in the age group of 31-40. Around 47% of the studypopulation had a history of manipulation of the external auditory canal. Around 32 % gave the history of theinstallation of either antibiotic drops or steroid drops into the ear. Around 97% of the study population hadblocked, 83% had pain and 77 % had itching. The discharge was present in 47% of the study population. Femaleprevalence was high and more than 88% was unilateral. Aspergillus species and Candida species were morecommonly present in the fungal culture. Around 88% had a bacterial infection along with fungal growth.Conclusion: the diagnosis of Otomycosis must be considered for all cases of ear discharge for prompt andaccurate treatment and to save time and suffering.

ABSTRACT

INTRODUCTION:Otomycosis is the fungal infection of EAC (External Auditory Canal) that is very commonly seen in Ear , Nose and Throat clinics .Local debridement and antifungals , topical or systemic is the treatment of choice but recurrences are very common and resistant to treatment.METHODS:Total 220 patients, divided into two groups each 110 in 'A' and 'B' were subjected to betadine (povidone - iodine )10% solution and Clotrimazole (1 %) drops treatment and response of treatment assessed on 5th , 10th and 20th day and analyzed.RESULTS :Out of 110 patients in each group on 5th day 21.8 % patients in group 'A', and 23.6 % in group B' showed no response. 70.9 % in group 'A' and 72.7 % in group 'B' were showed good response at evaluation of 20th day of treatment.CONCLUSION :In our study, betadine (10% solution) and Clotrimazole (1 %) drops were equally effective in treatment of otomycosis. Betadine(10% solution) is low cost, non-ototoxic, nonresistant and equally effective in bacterial and fungal infection. That's why this study support betadine 10% solution as treatment of choice for otomycosis specially in developing countries

ABSTRACT

Background: Otomycosis can be defined as a fungal infection of the external auditory canal, frequentlyencountered in the general otolaryngology department. Otomycosis is more commonly reported in hot andhumid climates and various individual as well as environmental factors predispose to this infection. Otomycosisis not only a prevalent condition but also follows a set patterns in patient demographics, predisposing factorsand, causative pathogens, which we aim to explore in this review. Objectives: In this review, we intend to shedlight on the prevalence of otomycosis, along with the characteristics of patients that are most commonlypresented with this condition including age, gender, occupation, socioeconomic class, as well as complains. Wealso aim to elucidate the various predisposing risk factors that increase the likelihood of contracting otomycosisand explore the usually encountered pathogenic causes. Materials and Methods: A review of relevant articlespublished between the years of 1975 to 2019 in English language was done using the databases of PubMed Pico,Google Scholar and Google, using the predetermined keywords. Conclusion: Otomycosis is a prevalent fungalear infection mostly seen in young patients between the ages of 21-30 years. Otomycosis mostly involves oneear, and bilateral involvement is mostly observed in immunodeficient patients. The most frequently reported riskfactors include self-cleaning of ears with objects such as Q-tips, wooden sticks, metal pickers, instillation ofmustard oil in ears, undue use of antibiotic ear drops, and swimming. Otomycosis causative organism isespecially Aspergillus and Candida while concomitant bacterial infection can be seen in several cases ofotomycosis, the most common implicated bacteria being staphylococcus aureus. This literature reviewhighlights the need for education to eradicate the aforementioned predisposing risk factors to reduce theincidence of otomycosis.

ABSTRACT

BACKGROUND AND OBJECTIVES: To determine the efficacy of filling the external auditory meatus with 1% clotrimazole at a single visit for the treatment of otomycosis. SUBJECTS AND METHODS: This prospective study included 40 patients who were referred to our clinic with complaints of ear itching, pain, and fullness, and were diagnosed with unilateral otomycosis. After cleaning the mycotic hyphae from the external auditory meatus, the ear canal was filled with 1% clotrimazole, using an intravenous catheter and syringe. The patients received follow-up examinations on post-treatment days 7, 15, and 45. RESULTS: The follow-up otomicroscopic examinations revealed that 95% of the ear canals were entirely clean and that all symptoms had resolved. The post-treatment scores of pain, aural fullness and itching were significantly lower than the pre-treatment scores (p < 0.01). CONCLUSIONS: Filling the external auditory meatus with 1% clotrimazole at a single visit is an easy, efficient, and cost-effective treatment for otomycosis. Additionally, high patient compliance makes this treatment superior to long-term topical therapy.

ABSTRACT

Abstract Introduction Otomycosis is a common problem in otolaryngology practice. However, we usually encounter some difficulties in its treatment because many patients show resistance to antifungal agents, and present high recurrence rate. Objectives To determine the fungal pathogens that cause otomycosis as well as their susceptibility to the commonly used antifungal agents. Additionally, to discover the main reasons for antifungal resistance. Methods We conducted an experimental descriptive study on 122 patients clinically diagnosed with otomycosis from April 2016 to April 2017. Aural discharge specimens were collected for direct microscopic examination and fungal culture. In vitro antifungal susceptibility testing was performed against the commonly used antifungal drugs. We tested the isolated fungi for their enzymatic activity. Results Positive fungal infection was found in 102 samples. The most common fungal pathogens were Aspergillus and Candida species, with Aspergillus niger being the predominant isolate (51%). The antifungal susceptibility testing showed that mold isolates had the highest sensitivity to voriconazole (93.48%), while the highest resistance was to fluconazole (100%). For yeast, the highest sensitivity was to nystatin (88.24%), followed by amphotericin B (82.35%), and the highest resistance was to terbinafine (100%), followed by Itraconazole (94.12%). Filamentous fungi expressed a high enzymatic ability, making them more virulent. Conclusion The Aspergillus and Candida species are the most common fungal isolates in otomycosis. Voriconazole and Nystatin are the medications of choice for the treatment of otomycosis in our community. The high virulence of fungal pathogens is owed to their high enzymatic activity. Empirical use of antifungals should be discouraged.

ABSTRACT

Abstract Introduction Otomycosis is a common diseases that can be associated with many complications including involvement of the inner ear and mortality in rare cases. Management of otomycosis can be challenging, and requires a close follow-up. Treatment options for otomycosis include local debridement, local and systemic antifungal agents and utilization of topical antiseptics. Objective This study was designed to compare the recovery rate of otomycosis using two therapeutic methods; topical betadine (Povidone-iodine) and clotrimazole. Methods In this single-blind clinical trial, 204 patients with otomycosis were selected using a non-probability convenient sampling method and were randomly assigned to two treatment groups of topical betadine and clotrimazole (102 patients in each group). Response to treatment was assessed at 4, 10 and 20 days after treatment. Data were analyzed using the independent t-test, Chi-Square and Fisher exact test in SPSS v.18 software, at a significance level of p < 0.05. Results The results showed that out of 204 patients with otomycosis, fungi type isolated included Aspergillus in 151 cases (74%), and Candida albicans in 53 patients (26%). On the fourth day after treatment, 13 patients (13.1%) in the group treated with betadine and 10 patients (9.8%) in the group treated with clotrimazole showed a good clinical response to treatment (p = 0.75). A good response to treatment was reported for 44 (43.1%) and 47 patients (46.1%) on the tenth day after the treatment (p = 0.85); and 70 (68.6%) and 68 patients (67.6%) on the twentieth day after treatment (p = 0.46) in the groups treated with betadine and clotrimazole, respectively. The response to treatment was thus not significantly different in the two groups. Conclusion In the present study the efficacy of betadine and clotrimazole was the same for the treatment of otomycosis. The result of this study supports the use of betadine as an effective antifungal in otomycosis treatment, helping to avoid the emergence of resistant organisms.

ABSTRACT

Otomycosis is a widely prevalent and often underdiagnosed fungal infection of the ear that is commonly seen in the tropical and subtropical regions. We performed mycological analysis on the scrapings and debris taken from the external auditory canal of 97patients clinically suspected to have otomycosis. Male sex, young age group, rural background and rainy season emerged as the major risk factors. 37 patients were positive on KOH mount and 39 patients were positive when cultured on SDA medium. The prevalence of confirmed otomycosis was 40.2 ± 4.98 (95.C .I =30.44 -49.96). Smear positivity was found to have a statistifically significant relationship with the prevalence of positive cultures in patients presenting as otomycosis. Aspergillusniger and fumigatus were the major isolates.

ABSTRACT

Azadirachta indica (neem) has been used for a long time in agricultural and alternative medicine. Neem had been proved effective against certain fungi that could infect human body. This pilot study aims to demonstrate the antifungal effect of Malaysian neem leaf extracts on the pathogenic fungi in otomycosis, Aspergillus niger and Candida albicans. This is a laboratory-controlled prospective study conducted at Universiti Sains Malaysia. The powder form of Malaysian neem leaf was prepared. Ethanol and aqueous extracts of the neem leaf was diluted with sterile water to establish five different concentrations of 50 g/ ml, 25 g/ml, 12.5 g/ml, 6.25 g/ml and 3.125g/ml. The extract was tested on Sabouraud Dextrose Agar suspended with Candida albicans and Aspergillus niger respectively. Well diffusion method was used and zone of inhibition was measured. Growth of the fungi was inhibited in both alcohol and aqueous extract concentrations. The minimum inhibitory concentration (MIC) of Malaysian neem aqueous extract against Candida albicans was 11.91 g/ml, neem ethanol extract against Candida albicans was 5.16 g/ ml, neem aqueous extract against Aspergillus niger was 7.73 g/ml and neem ethanol extract against Aspergillus niger was 9.25 g/ml. Statistical analysis showed that the antifungal activity of Candida albicans is better in alcohol neem than aqueous extract (p<0.001) but aqueous neem extract is better than alcohol extract (p<0.001) for Aspergillus niger.Malaysian neem has significant antifungal effect towards Aspergillus niger, best in aqueous extract and towards Candida albicans, was best in alcohol extract.

ABSTRACT

Introduction: Otomycosis is a superficial mycotic infection of the external auditory canal that is caused by opportunistic fungi. It is a common fungal infection of the ear that is worldwide in distribution. The infection usually characterized by inflammation, pruritus, trauma to external auditory canal, scaling and severe discomfort such as suppuration and pain. We have tried to clarify the different causative factors & predisposing factors for otomycosis in our environment. Material & Methods: In this study we were including 100 patients (53 female and 47 male) with presumptive diagnosis of otomycosis. We performed mycological analysis on swab or fungal ball from external auditory canal of 100 patients. The diagnosis was confirmed micro biologically by direct microscopy (10% KOH mount) and fungal culture methods. Results: Otomycosis was more common among females as compared to males & also common in age groups of 20-35 yrs. The most common fungal pathogens isolated were Aspergillus niger (75.82%) followed by Aspergillus fumigatus( 13.19 %), Candida albicans ( 7.69 %) & Aspergillus flavus ( 3.3 %). while bacterial co infection/ super infection was detected in 6 cases. Conclusion: In this study we observe that otomycosis is unilateral condition more common in young age housewives and farmers particularly during summer and rainy season.

ABSTRACT

La otitis externa constituye entre el 5 por ciento y 30 por ciento de las consultas de urgencia ORL y afecta al 10 por ciento de la población al menos 1 vez en la vida. La gran mayoría son de causa bacteriana, sólo el 15 por ciento a 20 por ciento son atribuidas a hongos. Las complicaciones son poco frecuentes alcanzando el 10 por ciento a 20 por ciento de los casos según la serie, siendo la perforación timpánica la más frecuente. Se presenta la evolución y tratamiento de 2 casos.


External otitis constitutes among 5 percent-30 percent of urgency ORL consultations and affects 10 percent of the population at least 1 time in their life. Most of them had a bacterial origin, only 15 percent to 20 percent are attributed to fungi. Otomycosis complications are slightly frequent reaching 10 percent to 20 percent of the cases according to diferent series, being the tympanic perforation the most frequent. We present 2 cases, their evolution and treatment.

ABSTRACT

BACKGROUND: Otomycosis is a mycotic disease of the external auditory meatus. Aspergillus is the most common pathogen. Despite the fact that a great number of fungi are considered as the cause of otomycosis, otomycosis due to dermatophytes occurs with great rarity. OBJECTIVE: The purpose of this study was to investigate clinical and mycological features of dermatophytosis in the external auditory meatus. METHODS: We performed a clinical and mycologic analysis of 17 patients who had been clinically and mycologically diagnosed with dermatophytosis of the external auditory meatus. In addition, amplication of TRS-1 and TRS-2 of the ribosomal DNA nontranscribed spacer was performed on strains of Trichophyton (T.) rubrum and T. raubitshcekii which were isolated from skin lesions of the external ear and cerumen in 6 patients. RESULTS: The ratio of male to female patients was 1.4:1. The age of patients were 6 to 72 and mean age of onset is 36.4. Eleven patients had concomitant dermatophytosis of other sites. Tinea unguium was combined in 7 cases, tinea pedis in 4 cases, tinea corporis in 3 cases, tinea manus in 2 cases and tinea cruris in 1 case. The positive rate of KOH examination was 88.2% and the positive rate of fungal culture on PDAC media was 88.2%. The most common organism cultured was T. rubrum (80.0%), followed by T. raubitschekii (13.3%) and T. mentagrophytes (7.7%). Ten patients were treated with topical terbinafine and seven patients with oral itraconazole, so all patients were cleared of fungi from the external auditory meatus and inflammation was resolved. With TRS-1 and TRS-2 amplication, 4 of 5 pairs of T. rubrum and 3 strains of T. raubitshcekii showed the same types regardless of the site in each patient. CONCLUSION: Dermatophytosis occurs rarely in the external auditory meatus but we experienced 17 cases of dermatophytosis at this site. With suspected otomycosis, dermatophytosis of the external auditory meatus and concomitant dermatophytosis must be investigated and treated simultaneously to prevent any recurrence.

ABSTRACT

Mycological analysis was carried out on debris, scraping or exudate samples from the external auditory canal(s) of 102 patients clinically suspected cases of otomycosis. The total number of samples taken from 102 patients were 108, of which 102 samples were obtained from one ear and 6 samples from the other ear. Predisposing factors contributing to such a presentation were dermatomycosis (51.22%), turban usage (29.26%), veil usage (14.63%) and swimming (4.88%). Only 82 (75.92%) samples were positive for the presence of fungal elements, of which 48(44.44%) specimens were smear and culture positive while 34(31.48%) were smear negative but culture positive. Males and females were almost equally affected, ratio being (1.1:1). Chief fungal isolates included Aspergillus niger (52.43%), Aspergillus fumigatus (34.14%), Candida albicans (11%), Candida pseudotropicalis (1.21%) and Mucor sp. (1.21%). Among 8 patients mixed fungal growth was obtained, while bacterial coinfection/ superinfection was detected in 14 cases.

ABSTRACT

Fungi have been recognized as a significant cause of external otitis and it may be the primary pathogen or be part of a mixed infection. In the immunocompromised host, fungus is capable of producing infection in inner ear or middle ear. Otomycoses are most frequently caused by Aspergillus spp. and Candida sap. There are few reports that Aspergillus species other than A. fumigatus, A. niger and f. flavus have caused chronic otitis media. We report two cases of chronic otitis media caused by Aspergillus ferrous in Korea. One case is a 7-year-old girl who had recurrent serous otorrhea and otalgia for 4 years, was reattended otolaryngology clinics with otorrhea of 3 days durations and another is a 6-year-old girl who had serous otorrhea for 2 months and 3 day fever, was attended otolaryngology clinics with them. Microscopic appearance and colony morphology from ear discharge cultures revealed A. ferrous. The infection responded well to topical ketoconazole therapy. This report should help to raise medical personnel's awareness of such human opportunistic fungal ear infections.

ABSTRACT

BACKGROUND: Because of recent concern about occurrence of otomycosis in otolaryngologic practice, we studied them. OBJECTIVE: The purpose of this study was to investigate clinical and mycological features of otomycosis. METHOD: We evaluated the clinical and mycological aspects of otomycosis in 38 patients from March 1996 to February 1998 in Dongguk University Hospital. RESULTS AND CONCLUSION: Otomycosis showed high incidence in the twenties (23.7%). The ratio of male to female patient was 1:1.5. The seasonal prevalence was highest in autumn. Most common symptoms were otorrhea (39.4%) followed by itching, obstruction sensation, otalgia, and hearing disturbance. The common causative organisms of otomycosis were Aspergillus(A.) niger (36.8%) followed by A. terreus (26.3%), A. flavus (21.1%), A. fumigatus (7.9%), Candida albicans (5.3%), and Mucor sp. (2.6%).
