Necrotizing otitis externa, otitis media, peripheral facial paralysis, and brain abscess in a thalassemic child after allogeneic BMT.

Severe infection is one of the major complications in the early and late post-bone marrow transplantation period. The authors report a thalassemic child who developed necrotizing otitis externa and otitis media, a very rare complication after bone marrow transplantation, and then peripheral facial nerve paralysis and brain abscess in the early period of bone marrow transplantation despite antibacterial and antifungal prophylaxis. Necrotizing otitis media is characterized by necrosis and sloughing of considerable areas in the middle ear and adjacent tissues and is an unusual disorder because of today's antibiotics. Granulocytopenia and background ear tissue exposed to previous repeated otitis media attacks may be the predisposing factors in this case. The authors conclude that the children with previous histories of recurrent otitis media should be prepared and monitored very carefully during bone marrow transplantation because of the risk of necrotizing otitis media, especially in the granulocytopenic period.

Management of otitis externa.

Otitis externa represents one of the most common reasons that pets are presented for veterinary attention. They are also some of the more frustrating entities practitioners are called on to deal with. Successful management depends on an understanding of the primary, predisposing, and perpetuating factors involved in the pathogenesis of otitis externa. Emphasis is then placed on establishing a diagnosis through physical examination, cytologic examination, culture and sensitivity testing, radiographs and biopsies. The general goals of management are to resolve, remove, or control primary factors, clean and dry the ear, reduce inflammation and resolve secondary infections. These goals are achieved through various cleaning techniques, topical, and systemic therapies. Therapeutic alternatives are given for otitis involving bacteria, Malassezia, otodectes, demodex, allergies, ceruminous disorders, the idiopathic inflammatory/hyperplastic otitis externa of cocker spaniels, "Swimmer's Ear", contact/irritant reactions, overtreatment, and concurrent otitis media.

Chronic otitis externa and otitis media treated by total ear canal ablation and ventral bulla osteotomy in thirteen dogs.

Ventral bulla osteotomy was combined with total ear canal ablation for the treatment of chronic otitis externa and otitis media in 13 dogs (14 ears) that had been refractory to medical and surgical treatments. Resolution of disease occurred in 11 dogs (12 ears). One dog with unilateral disease underwent a second operation before achieving a good result. One dog was euthanatized for persistent unilateral disease after three surgical procedures. The recurrence of disease in these two dogs (15%) was associated with remnants of ear canal integument within the osseous horizontal canal or tympanic bulla. Facial paralysis occurred in four dogs (31%) and there were no complications in eight dogs (62%). This technique shows no advantage over lateral bulla osteotomy combined with total ear canal ablation for the treatment of chronic otitis externa and otitis media.

Otitis externa.

Otitis externa is a broad term for a disease state that includes inflammation or infection of the external auditory canal and auricle. It can range from mild inflammation and discomfort to a life-threatening disease. Treatment of otitis externa is dependent on a thorough understanding of anatomy and physiology of the external ear canal, a knowledge of the microbiology of potential pathogens, and familiarity with clinical presentation, so that an accurate and timely diagnosis can be reached.

Are topical antibiotics necessary in the management of otitis externa?

Otitis externa is an inflammatory disorder of the skin of the outer ear canal frequently associated with bacterial or fungal infection. It is normally treated with aural toilet and topical preparations containing antibiotic/antifungal and steroid preparations. A group of 39 patients presenting with otitis externa were randomized in a double-blind manner into those receiving drops containing an aminoglycoside and steroid preparation and those receiving the same preparation without the aminoglycoside. All patients were reviewed on days 0, 3, 7 and 11 of a 14-day course of drops and their response to medication monitored. Patients documented their symptoms at each appointment and clinical response was also measured by a blinded observer. The study suggests that an aminoglycoside antibiotic conveys no significant benefit in this condition.

A review of techniques for the investigation of otitis externa and otitis media.

Otitis externa, inflammation of the externa ear canal, is relatively easy to diagnose based on the history and physical examination findings. The diagnosis of otitis media, inflammation of the middle ear cavity, is more challenging, with the work-up being both costly and, at times, invasive. The pathogenesis of otitis externa has been classified into predisposing, primary, and perpetuating factors. It is critical to the management of ear disease that the clinician recognize and investigate which factors are contributing to each individual patient's ear disease. Failure to identify and address the primary and/or predisposing factors is the most common cause of chronic recurrent otitis externa. Chronic inflammation of the ear canal leads to the development of the perpetuating factors, which may be the major reason for treatment failure, regardless of the primary cause of the ear disease. In this article, the predisposing, primary, and perpetuating factors involved in ear disease will be presented, along with a review of the techniques used in the diagnosis of otitis externa and otitis media.

Primary care management of otitis externa.

Otitis externa (OE) is an acute, painful inflammatory condition of the external auditory canal that affects all age groups and accounts for about half of all patients presenting with ear pain. Common causes are gram-negative bacteria, Staphylococcus aureus, fungi, and dermatologic conditions such as eczema, seborrhea, and psoriasis. Risk increases with prolonged exposure to heat and moisture, especially in those who swim frequently or live in a tropical climate. Treatment involves cleaning the canal thoroughly and instilling ototopical broad-spectrum antibiotics. Although OE is relatively benign and easy to treat in the primary care setting, it can have life-threatening complications, especially in diabetic and immunocompromised patients. This article reviews the differential diagnosis, outlines treatment, and discusses preventive measures. A patient-education sheet is provided.

New combination for the therapy of canine otitis externa. I. Microbiology of otitis externa.

In order to compound a new drug combination against canine otitis externa (OE), 515 dogs affected with OE were subjected to physical examination and microbiological analysis of their ear exudates. OE was erythematous-ceruminous in 83 per cent and suppurative in 17 per cent of the patient material. Erythematous-ceruminous inflammations were characterised by severe pruritus and accumulation of brownish, greasy cerumen in the auditory canal. The yeast Malassezia pachydermatis was isolated from the ears of 76 per cent of the dogs, often in combination with Staphylococcus intermedius bacteria. M pachydermatis showed the most sensitivity, in decreasing order of efficacy, to ketoconazole, econazole, clotrimazole, miconazole and nystatin. S intermedius isolates were most sensitive to amoxycillin-clavulanic acid, enrofloxacin, cephalexin and gentamicin. The microorganism most frequently isolated from dogs with suppurative OE was Pseudomonas aeruginosa; in some cases Proteus, Streptococcus and Pasteurella were also isolated. The P aeruginosa isolates showed the highest sensitivity to gentamicin, polymyxin B and tobramycin.

Allergic otitis externa.

Chronic otitis externa is a common condition, which is usually successfully treated by topical medications and aural toilet. In cases that persist despite conventional treatment, a diagnosis of allergic otitis externa should be considered. Sensitization to otic medications (secondary contact otitis) is not uncommon. Topical aminoglycosides are the most common sensitizers although many components of topical preparations can cause sensitization. Patients who may have developed allergic otitis externa should undergo patch testing. Otolaryngologists should consider using topical antibiotics with a low allergenic potential and avoiding neomycin when treating patients with otitis externa. Primary contact otitis may occur to metals used in earrings and also to hearing aid moulds. Treatment of both primary and secondary contact otitis consists of identifying the allergen, avoiding further contact and use of simple preparations avoiding common sensitizers.

[Bacteriologic evaluation of otitis externa and chronic otitis media].

The authors present results of bacteriological examinations in 187 patients with chronic otitis media (OMC) and otitis externa treated in ENT Department, Medical University of Gdańsk in the years 1997-1998. Ear swabs and aspirates were investigated for aerobes and anaerobes 254 bacterial isolates were obtained. Among 150 patients with OMC aerobes were isolated in 130 (86.7%) in 13 (8.5%) mixed aero-anaerobes flore and in 20 (19.3%) no bacterial growth was observed. From patients with COM there were 199 bacterial isolates among them 177 aerobes cultures, 13 anaerobes and 9 fungal. From the external ear canal there were 55 cultures, among them 45 (81.8%) aerobes, 6 (10.9%) mixed aero-anerobes and 4 (7.3%) fungal. The most frequent observed bacteria were Staphylococcus aureus, Pseudomonas aeruginosa and Proteus mirabilis which showed the best susceptibility on ciprofloxacine and amikacine.

What causes acute otitis externa?

External otitis is an extremely common condition and can affect between five to twenty per cent of the patients attending ENT clinics (Hawke et al., 1984). Its precise pathogenesis remains unclear, despite several aetiological classifications in the literature. The aim of this study was to investigate the relationship between infection, water exposure and trauma and the development of acute otitis externa. The study comprised 100 patients with their first attack of otitis externa and 150 age and sex matched controls. In only 40 per cent of cases could a primary microbiological cause be found. There was no significant statistical difference found between the two groups regarding the use of agents capable of traumatizing the external canal. Regular swimming, showering and hair washing were significantly more common in patients with acute otitis externa. Allergic disorders were nearly three times more common in the external otitis group suggesting a possible immunological aetiology.

Otitis externa sicca/fibrotising external otitis (FEO) as a complication of Sjögren's syndrome.

Sjögren's syndrome (SS) is a condition characterized by sicca symptoms and by autoimmune features. We describe two SS patients with otitis externa fibroticans/sicca. One of these 2 patients developed a lesion of the tympanic membrane making it necessary to perform a tympantomy and meatoplasty. Our findings suggest firstly that the epithelial cell-mediated secretion of lamellar bodies and the production of the permeability barrier are defective in SS. Secondly, local moisturing and/or topical corticosteroid treatment in SS patients with sicca symptoms in the auditory canal could help to avoid reconstructive surgical treatment.
