RESUMO

The article deals with the problem of inflammatory diseases of the external ear. A review of pruritic dermatoses of the external auditory canal was carried out. It has been shown that in chronic dermatoses, the contamination of the skin with bacterial and fungal pathogens significantly increases, which leads to a high risk of developing secondary infectious pathological processes. Treatment of dermatological inflammatory ear diseases includes careful daily hygiene of the external auditory canal and pharmacotherapy, a key aspect of which is the use of topical etiotropic, anti-inflammatory, and symptomatic drugs. The advantage of the combined drug candiderm is described, which, thanks to the unique combination of beclomethasone, gentamicin and clotrimazole in the composition, effectively relieves the symptoms of external ear dermatoses.

RESUMO

OBJECTIVES: The role of traditional nuclear medicine studies in the management of malignant otitis externa (MOE) is unclear and there are ongoing debates regarding their diagnostic value. The authors perform a systematic review and meta-analysis to assess the sensitivity and specificity of traditional nuclear medicine studies in the diagnosis of MOE. METHODS: In accordance with PRISMA guidelines, a query of the Medline, Embase, Web of Science, and Cochrane databases was undertaken. The primary outcomes of interest were the sensitivity and specificity of traditional nuclear medicine studies to detect MOE. RESULTS: Of the initial 1317 hits from the four databases, 20 articles with a combined 608 patients were ultimately included in the review. The pooled sensitivities for Technetium-99 and Gallium-67 were 85.1% (95% CI, 72.0-98.1%) and 71.2% (95% CI, 55.1-87.3%) respectively. The available evidence suggested poor specificity of these modalities, but was insufficient for meta-analysis. Neither modality was shown to be effective in the assessment of disease resolution. CONCLUSION: The sensitivities of Technetium-99 and Gallium-67 to detect MOE are less favorable than was initially thought. Given this finding and their poor specificity, lack of anatomic resolution, unproven ability to detect disease resolution and variable availability, this review does not support the routine use of these studies in the management of MOE.

RESUMO

The emerging pathogen Candida auris is isolated mostly from hospitalized patients and often shows multidrug resistance. We report on the isolation of this yeast in Austria from an outpatient's auditory canal. The isolate showed good susceptibility against antifungals except for echinocandins; the patient was treated successfully with topical administration of nystatin.

RESUMO

INTRODUCTION: Necrotising otitis externa (NOE) is a rare infection causing skull base osteomyelitis. The evidence regarding NOE consists mostly of case series. Hence, there is a limited evidence base to guide decision-making. This survey aims to report the experience of 221 otolaryngologists in this condition. MATERIALS AND METHODS: Internet survey administered to the membership of the British Association of Otorhinolaryngology - Head and Neck Surgery (ENT UK). RESULTS: Respondents' detailed replies on diagnosis, treatment and follow up are presented. One third of respondents reported increasing incidence of NOE. Over 80% diagnosed NOE based on pre-existing risk factors, severe pain, non-resolution of infection and CT scan. Most respondents managed NOE with intravenous antibiotics (90%) and blood sugar control (82%). There was less agreement in certain aspects of management including the role of surgery and the nature and duration of follow up. CONCLUSIONS: Our survey provides a picture of NOE management in the UK. While there is consensus in some aspects of NOE management, other aspects attract widely differing answers. This may reflect the lack of strong evidence in the literature. Future work should aim to address this.

RESUMO

We reviewed 25 cases of patients diagnosed with necrotizing otitis externa in our tertiary university-affiliated medical center between 2009 and 2015. Mean overall hospitalization duration was 14.52days, 95% of the patients showed specific seasonal incidence. Mean duration of symptoms prior to hospitalization was 6weeks and the duration correlated with outcome. Only 8% of the patients presented with cranial neuropathies; however, this presentation correlated with adverse outcome. Pseudomonas aeruginosa was the main causative organism (50%), with a 30% multidrug-resistance rate. A high rate (35%) of fungal pathogens was noted. Seventeen patients (68%) were eventually operated; however, only 5 patients needed extensive surgery under general anesthesia. Computed tomography (CT) evidence of adjacent structures' involvement correlated with adverse outcome. Eighty percent of our patients improved clinically. The overall death rate was 12% and the disease-related mortality rate was 8%. Our findings state the importance of limited surgical intervention and microbiologic cultures in disease treatment. This is particularly important in patients with cranial neuropathies and CT finding of adjacent structural involvement that correlate with adverse prognosis. A rising pseudomonal antibiotic resistance and fungal infections may challenge antibiotic treatment in the future.

RESUMO

The objective of the present study was to evaluate the clinical effectiveness and safety of the local application of triderm for the treatment of diffuse external otitis. The study included 68 patients presenting with bacterial and fungal diffuse external otitis. The treatment in the form of local empiric therapy was continued till the results of microbiological treatment became apparent. The beneficial outcome achieved in 91.2% of the patients was clinically manifest as the regression of the inflammatory process in the external auditory meatus. No complications, such as ototoxic events, either local or systemic allergic reactions, were documented. The authors substantiate the possibility of the application of the medication under consideration for the treatment of diffuse external otitis based on the knowledge of the mechanism of the actin of its constituent components, viz. betamethasone, dipropionate, gentamicin sulfate, and clotrimazole, taking into account the occurrence of the most common causative agents of diffuse external otitis. It is concluded that triderm is a safe medication for the local application and, probably, for the initial empiric therapy of diffuse external otitis to be continued till the results of the microbiological treatment become apparent.

RESUMO

Scedosporium apiospermum is an ubiquitous fungus responsible for various infections in immunocompromised and immunocompetent patients. Ear infections are infrequent. We report an exceptional case of S. apiospermum external otitis complicated by temporomandibular joint arthritis. After 6 months of antibiotherapy, diagnosis was established by mycological analysis of external auditory canal and infratemporal fossae needle sampling. A satisfactory outcome was obtained after 2 months of voriconazole alone. We have reviewed 15 cases of S. apiospermum otitis. Seven of these patients were immunocompromised. Most common clinical presentation included a chronic external otitis lasting months or years before complication stage. Most common clinical features included recurrent unilateral otalgia (11/15) and purulent otorrhea (13/15). Diagnosis was often made at later stage (12/15) with local extension to bones and/or soft tissues (9/15) or cerebral lethal dissemination (3/15).The extremely low incidence of S. apiospermum otomycosis and its non-specific presentation results in a frequent diagnosis delay. A mycological investigation should be performed in case of persistent external otitis and/or osteolysis despite prolonged antibiotic treatment to prevent further extension of the disease.

RESUMO

OBJECTIVE: Malignant otitis externa (MOE) is an invasive infection of the temporal bone that is classically caused by Pseudomonas aeruginosa. Increasingly, however, nonpseudomonal cases are being reported. The goal of this study was to evaluate and compare the clinical presentation and outcomes of cases of MOE caused by Pseudomonas versus non-Pseudomonas organisms. STUDY DESIGN: Retrospective case series with chart review. SETTING: Tertiary care institution. SUBJECTS AND METHODS: Adult patients with diagnoses of MOE between 1995 and 2012 were identified. Charts were reviewed for history, clinical presentation, laboratory data, treatment, and outcomes. RESULTS: Twenty patients diagnosed with and treated for MOE at the University of Pittsburgh Medical Center between 1995 and 2012 were identified. Nine patients (45%) had cultures that grew P aeruginosa. Three patients (15%) had cultures that grew methicillin-resistant Staphylococcus aureus (MRSA). Signs and symptoms at presentation were similar across groups. However, all of the patients with Pseudomonas had diabetes, compared with 33% of MRSA-infected patients (P = .046) and 55% of all non-Pseudomonas-infected patients (P = .04). Patients infected with MRSA were treated for an average total of 4.7 more weeks of antibiotic therapy than Pseudomonas-infected patients (P = .10). Overall, patients with non-Pseudomonas infections were treated for a total of 2.4 more weeks than Pseudomonas-infected patients (P = .25). CONCLUSIONS: A high index of suspicion for nonpseudomonal organisms should be maintained in patients with signs and symptoms of MOE, especially in those without diabetes. MRSA is an increasingly implicated organism in MOE.

RESUMO

OBJECTIVES: Diagnostic and therapeutic practice guidelines have been established for classical forms of benign otitis externa. However, these guidelines do not include unusual forms of the disease, especially "invasive" otitis externa. No consensual diagnostic flow diagram has been published in the literature, which frequently results in delayed diagnosis and inappropriate primary care management. The objective of this study was to analyse the primary care management practices of malignant otitis externa (MOE). MATERIAL AND METHODS: Retrospective study of 22 cases of MOE managed in our tertiary care centre over a 6-year period (2004-2010). RESULTS: All but one of the patients presented a systemic or local predisposing factor. The mean interval between onset of the first symptoms and referral to our tertiary care centre was 13weeks (range: 1 to 12months); 77% of patients were referred by a private ENT specialist, 14% were referred by a an emergency department and 9% were referred by a hospital department. Seventeen patients (81%) had received one or more courses of inappropriate systemic antibiotics during this interval (oral in 15 cases, parenteral in two cases, multiple treatments in 13 cases). The mean duration of each course of antibiotics was 12days (range: 7 to 21days). All patients also received local antibiotic ear drops (aminoglycosides or fluoroquinolones). CONCLUSIONS: The practice audit constantly revealed delayed management of MOE, often resulting in inappropriate antibiotic prescriptions. Publication of practice guidelines for primary and secondary care practitioners therefore appears to be essential.

RESUMO

Se presenta el caso clínico de un niño que presentó una otitis externa a los dos meses de edad. El cultivo ótico mostró un Staphylococcus aureus resistente a meticilina (SARM). Se realizó un estudio familiar en ambos padres resultando los cultivos nasales negativos. Posteriormente, estudiando la historia familiar se supo que la madre había tenido en el momento del parto un cultivo de herida quirúrgica positivo a SARM con el mismo antibiograma que el que presentaba el niño. Como en ese periodo de tiempo no se había hecho ningún tratamiento en el niño se volvió a repetir el cultivo para valorar la necesidad o no de tratamiento persistiendo el SARM. Se realizó tratamiento local con ciprofloxacino, siendo el cultivo de control negativo(AU)


We reported the case of a child two months old, with external otitis by Methicillin-Resistant Staphylococcus Aureus (MRSA). Nasal swabs were collected from the father and the mother with negative result. An intra-familial vertical transmission was identified later(AU)

RESUMO

INTRODUCTION: Necrotizing external otitis (NEO) is a devastating and life-threatening infection in the external auditory canal and the temporal bone. The aim of this paper is to evaluate the diagnostics and treatment of NEO and to recommend new guidelines. MATERIAL AND METHODS: Eleven patients were retrospectively enrolled under the code DH609 otitis externa without specification from 1 January 2000 to 31 December 2009. Records were reviewed to register: age, symptoms, clinical findings, comorbidity, imaging, microbiology and treatment. RESULTS: The median age was 75 years and the median time of therapy at the hospital was 6.3 months. All patients belonged to a risk group. A diagnostic delay was found resulting in further progression of the disease. In contrast to current international recommendations, the treatment consisted mostly of local antibiotics in combination with surgery. All patients survived, but most patients were left with hearing loss and psychiatric problems. CONCLUSION: A greater awareness of diagnostic criteria and a shift from local antibiotics to prolonged systemic monotherapy with ciprofloxacin in accordance with international concepts is recommended. Surgery should be left for extensive and refractory cases only. A list of diagnostic criteria and treatment guidelines is presented. FUNDING: Not relevant. TRIAL REGISTRATION: Not relevant.

RESUMO

The authors present the case of a 76-year-old male who presented with right-sided recurrent malignant otitis externa (MOE) and skull-base osteomyelitis. His management involved aggressive antimicrobial therapy and multiple hyperbaric oxygen treatments. After resolution of his right-sided infection, the patient returned a short time later with symptoms and findings consistent with new, left-sided MOE with involvement of the left skull-base. With repeat treatment, the patient is now cured of his infection but poses a challenge to the treating team about future management.

RESUMO

Aspergillus and Candida spp are the most frequently isolated fungi in patients with otomycosis. The diagnosis of otitis externa relies on the patient's history, otoscopic examination under microscopic control, and imaging studies. Direct preparation of the specimens, particularly with optical brighteners, mycologic culture, and histologic examination, is very important and strongly recommended for the correct diagnosis. Patients with noninvasive fungal otitis externa should be treated with intense débridement and cleansing, and topical antifungals. Topical antifungals, such as clotrimazole, miconazole, bifonazole, ciclopiroxolamine, and tolnaftate, are potentially safe choices for the treatment of otomycosis, especially in patients with a perforated eardrum. The oral triazole drugs, itraconazole, voriconazole, and posaconazole are effective against Candida and Aspergillus, with good penetration of bone and the central nervous system. These drugs are essential in the treatment of patients with malignant fungal otitis externa complicated by mastoiditis and meningitis.

RESUMO

OBJECTIVES: To evaluate the efficacy and safety of a therapeutic bacteriophage preparation (Biophage-PA) targeting antibiotic-resistant Pseudomonas aeruginosa in chronic otitis. DESIGN: Randomised, double-blind, placebo-controlled Phase I/II clinical trial approved by UK Medicines and Healthcare products Regulatory Agency (MHRA) and the Central Office for Research Ethics Committees (COREC) ethical review process. SETTING: A single specialist university hospital. PARTICIPANTS: 24 patients with chronic otitis with a duration of several years (2-58). Each patient had, at the time of entry to the trial, an ear infection because of an antibiotic-resistant P. aeruginosa strain sensitive to one or more of the six phages present in Biophage-PA. Participants were randomised in two groups of 12 treated with either a single dose of Biophage-PA or placebo and followed up at 7, 21 and 42 days after treatment by the same otologist. Ears were thoroughly cleaned on each occasion and clinical and microbiological indicators measured. MAIN OUTCOME MEASURES: Physician assessed erythema/inflammation, ulceration/granulation/polyps, discharge quantity, discharge type and odour using a Visual Analogue Scale (VAS). Patients reported discomfort, itchiness, wetness and smell also using a VAS. Bacterial levels of P. aeruginosa and phage counts from swabs were measured initially and at follow-up. At each visit patients were asked about side effects using a structured form. Digital otoscopic images were obtained on days 0 and 42 for illustrative purposes only. RESULTS: Relative to day 0, pooled patient- and physician-reported clinical indicators improved for the phage treated group relative to the placebo group. Variation from baseline levels was statistically significant for combined data from all clinic days only for the phage treated group. Variation from baseline levels was statistically significant for the majority of the patient assessed clinical indicators only for the phage treated group. P. aeruginosa counts were significantly lower only in the phage treated group. No treatment related adverse event was reported. CONCLUSION: The first controlled clinical trial of a therapeutic bacteriophage preparation showed efficacy and safety in chronic otitis because of chemo-resistant P. aeruginosa.
