Otomycosis is a relatively frequent disorder (21.7% of the cases of external otitis) of fungi origin. Otomycoses can be discriminated from bacterial otitis by the following symptoms: itching, absence of otalgy, discharge and negative response to different local antibiotic therapies. Our study involves 148 cases of otomycosis and their therapy. Recovery was obtained in approximately 10 days.

The object of this investigation was to assess the frequency of itching in the external auditory meatus in individuals who use hearing aid ear plugs (OP) and, simultaneously, to assess the cause of the itching. Seventy-six of the patients examined consecutively in the audiological department (ages 34-89 years) were questioned about itching and were submitted to an objective ear, nose and throat examination, audiometry and culturing from the external meatus for bacterial and fungal growth. In 20 patients, patch tests were made for allergic reactions from which the ear plugs were made (heat polymerized methyl methacrylate). None of the 20 patients had become sensitized. Itching in the external auditory meatus was found to be a side effect of employment of ear plugs with an incidence of 39% as opposed to only seven in ears without ear plugs (p less than 0.05). The incidence of itching was not reduced in ears with a ventilation channel in the ear plug. In 38% of the itching ears no objective changes were observed and, in the remaining cases, the changes were frequently limited. Potentially pathological bacterial growth was found to be significantly more in ears with ear plugs (1- greater than 16%, p less than 0.05) and in itching ears (4- greater than 24%, p less than 0.05). In ears with potentially pathogenic bacteria, objective changes were nearly always found. In the vast majority of cases, the potentially pathogenic bacteria were Gram-negative, corresponding to the findings in external otitis in the tropics and mixed infections with fungi were frequently present.(ABSTRACT TRUNCATED AT 250 WORDS)

Canine atopy is a common dermatologic disorder. Because the disease most frequently strikes young dogs, lifetime management strategies are necessary. Consideration must be given to the treatment of pruritus and secondary manifestations of the allergy, such as pyoderma, otitis externa, and seborrhea, to manage these patients successfully. The use of glucocorticoid therapy and hyposensitization are discussed.

An otomycosis was found in 80 cases of external otitis on a total of 132. Itching was the characteristic beginning, rapidly followed by pain, conductive hearing loss, tympanic perforation. Aspergillus was isolated in 81.7% of cases: in particular, A. niger in 67.1% of cases. A. flavus in 13.4% A. fumigatus in 1.2%. Candida albicans was isolated in 11% of cases. A statistical analysis based on chi 2 test was performed to evaluate the role of possible predisposing factors. Highly significant factors resulted to be working in gardens (P less than 0.005) or using mechanical removing devices. Not significant resulted to be swimming, water irrigations or antibiotic therapies: however infirmities were often not reliable. The above mentioned highly significant factors seem to be able to determinate the overlaying of otomycosis.

Otomycosis of the auditory canal is common in Burma. Of 346 cases of otitis externa seen in a hospital outpatient clinic during two consecutive rainy seasons, 189 were due to fungus infection. Aspergillus species were the fungi isolated most frequently. Infection was most commonly due to self-manipulation. Itching and tinnitus were common complaints. Treatment by local cleansing and application of antifungal agents was effective, 10% 5-fluorocytosine ointment being most successful.

The symptoms and signs as well as the bacterial flora from the auditory canals of 54 Tanzanian patients (74 ears) living in Dar es Salaam and suffering from otitis externa were studied. Itching and pain were the most common symptoms and erythema and secretion were the prevalent clinical findings. Pseudomonas aeruginosa was found in 38%, Aspergillus in 24%, Staphylococcus aureus in 18% and Candida albicans in 14%. Bacterial cultures from the auditory canals of 21 healthy subjects revealed only normal skin flora.

A prospective study of 40 cases of acute otitis externa and 99 cases of chronic otitis externa in unselected patients revealed that otitis externa affects males and females with a similar frequency. The peak incidence occurs in the summer and early fall months of the year. Exposure to water, previous use of ear drops, and cotton-tipped applicators predisposed to both acute and chronic otitis externa. Hearing aid ear molds appear to be a predisposing factor in the development of chronic otitis externa. Pain, itching, discharge, and hearing loss were the most common presenting complaints in both acute and chronic otitis externa. The discharge in chronic otitis externa is more commonly purulent, whereas in acute otitis externa it is more commonly mucoid. The tympanic membrane is not frequently involved in acute otitis externa; however, in chronic otitis externa changes in the tympanic membrane were more often encountered. Most infections were of a pure bacterial origin, primarily Pseudomonas aeruginosa and Staphylococcus aureus. Fungi were the causative organisms more commonly in chronic otitis externa than in acute otitis externa (Figure 7). It was found that previous usage of ear drops was more often associated with otomycosis in acute otitis externa and yet was not related to a higher frequency of otomycosis in chronic otitis externa. The presence of a foreign material, such as an ear mold, was associated with a greater frequency of mixed infections (bacteria and fungi) in the group with chronic otitis externa. The presence of a greenish discharge or foul odor was not related to any particular organism.

A comparison between a plain steroid lotion and a steroid lotion with an additional keratolytic and antiseptic was conducted in order to assess the value, if any, of additives in the treatment of dry external otitis. Sixty patients with dry external otitis were treated with either a plain steroid lotion or a steroid lotion with additives. Assessments were made prior to and after one week of treatment regarding erythema, oedema, secretion, itching, pain and spontaneously reported side-effects. No significant differences in efficacy were observed between the treatments. Statistically significant differences in favour of the plain steroid lotion were found with regard to reduction of erythema and occurrence of spontaneously reported side-effects. These findings invalidate the demands of additives to steroid lotions in the treatment of dry external otitis.

Vibrio alginolyticus is a microorganism of marine environment which occasionally may cause infections on man. We described four patients with external otitis who had prolonged contact with sea water presented itch and seropurulent fluid. V. alginolyticus was isolated by pure culture from ear fluid of three of them and associated to V. fluvialis in another. The administration of ciprofloxacin in three cases, and ceftazidime in the other succeeded in the remission of the symptoms.
