Abstract
Acute otitis externa also called as "Swimmers ear" is commonly seen in all age groups. It is a very common condition, severely painful, characterised by otalgia, otorrhoea, conductive hearing loss and an oedematous ear canal. There is dearth of evidence based treatment guidelines leading to difference of opinion in its treatment particularly in the usage of systemic antibiotics and local antibiotics. To evaluate the clinical efficacy of oral antibiotics in two different protocols in treatment of acute otitis externa. A total of 80 patients with clinically diagnosed otitis externa were included into the study. Group A treated with systemic antibiotics and Group B without antibiotics based on Senturia grading. Response to the treatment was assessed with otoscopic finding and visual analogue scale. Standard analysis was performed with the statistical p value of less than 0.05 which is considered as significant. Group A treated with oral antibiotics had better improvement of the VAS scores in S2b and S2c grades when compared with Group B. However, there was no significant difference in both groups with S1 and S2a grades with or without antibiotics. Oral antibiotics are effective only in cases with severe odema and higher grades of AOE. In cases with initial or milder to moderate AOE the role of antibiotics is still doubtful and hence use of antibiotics to be considered cautiously in this antibiotic resistance era. A combination of good local treatment and IG wicks can produce almost similar results without antibiotics except in severe odematous AOE cases.

Antimicrobial resistance and genotyping of Pseudomonas aeruginosa isolated from the ear canals of dogs in Japan. Front Vet Sci 2023; 10:1074127. [PMID: 37546340 PMCID: PMC10397403 DOI: 10.3389/fvets.2023.1074127] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Accepted: 05/22/2023] [Indexed: 08/08/2023] Open
Abstract
The strong bond between dogs and their owners creates a close association that could result in the transfer of antibiotic-resistant bacteria from canines to humans, potentially leading to the spread of antimicrobial resistance genes. Pseudomonas aeruginosa, a common causative agent of persistent ear infections in dogs, is often resistant to multiple antibiotics. Assessing the antimicrobial resistance profile and genotype of P. aeruginosa is crucial for the appropriate use of veterinary pharmaceuticals. However, in recent years, few studies have been conducted on this bacterium in Japan. We determined the antimicrobial resistance profile and genotype of P. aeruginosa isolated from the ear canal of dogs in Japan in 2020. Analysis of antimicrobial resistance using disk diffusion tests indicated a high frequency of resistance to most antimicrobial agents. Particularly, 29 isolates from the ear canals of the 29 affected dogs (100%) were resistant to cefovecin, cefpodoxime, and florfenicol; however, they were susceptible to cefepime and piperacillin/tazobactam. Only 3.4, 10.3, and 10.3% of the isolates were resistant to ceftazidime, tobramycin, and gentamicin, respectively. Furthermore, upon analyzing the population structure using multilocus sequence typing, a considerably large clonal complex was not observed in the tested isolates. Three isolates, namely ST3881, ST1646, and ST532, were clonally related to the clinically isolated sequence types in Japan (such as ST1831, ST1413, ST1812, and ST1849), which is indicative of dog-to-human transmission. Considering the variation in antibiotic resistance compared to that reported by previous studies and the potential risk of dog-to-human transmission, we believe that the survey for antimicrobial resistance profile and population structure should be continued regularly. However, the prevalence of multidrug-resistant P. aeruginosa in dogs in Japan is not a crisis.

Etiology, Predisposing Factors, Clinical Features and Diagnostic Procedure of Otomycosis: A Literature Review. J Fungi (Basel) 2023; 9:662. [PMID: 37367598 DOI: 10.3390/jof9060662] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 06/01/2023] [Accepted: 06/06/2023] [Indexed: 06/28/2023] Open
Abstract
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.

The resistance mechanisms of bacteria against ciprofloxacin and new approaches for enhancing the efficacy of this antibiotic. Front Public Health 2022; 10:1025633. [PMID: 36620240 PMCID: PMC9815622 DOI: 10.3389/fpubh.2022.1025633] [Citation(s) in RCA: 40] [Impact Index Per Article: 20.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Accepted: 11/22/2022] [Indexed: 12/24/2022] Open
Abstract
For around three decades, the fluoroquinolone (FQ) antibiotic ciprofloxacin has been used to treat a range of diseases, including chronic otorrhea, endocarditis, lower respiratory tract, gastrointestinal, skin and soft tissue, and urinary tract infections. Ciprofloxacin's main mode of action is to stop DNA replication by blocking the A subunit of DNA gyrase and having an extra impact on the substances in cell walls. Available in intravenous and oral formulations, ciprofloxacin reaches therapeutic concentrations in the majority of tissues and bodily fluids with a low possibility for side effects. Despite the outstanding qualities of this antibiotic, Salmonella typhi, Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa have all shown an increase in ciprofloxacin resistance over time. The rise of infections that are resistant to ciprofloxacin shows that new pharmacological synergisms and derivatives are required. To this end, ciprofloxacin may be more effective against the biofilm community of microorganisms and multi-drug resistant isolates when combined with a variety of antibacterial agents, such as antibiotics from various classes, nanoparticles, natural products, bacteriophages, and photodynamic therapy. This review focuses on the resistance mechanisms of bacteria against ciprofloxacin and new approaches for enhancing its efficacy.

Efficacy and Safety of Ciprofloxacin Plus Fluocinolone Acetonide Among Patients With Acute Otitis Externa: A Randomized Clinical Trial. JAMA Netw Open 2022; 5:e2221699. [PMID: 35834251 PMCID: PMC10881221 DOI: 10.1001/jamanetworkopen.2022.21699] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Accepted: 03/24/2022] [Indexed: 11/14/2022] Open
Abstract
Importance Ciprofloxacin, 0.3%, plus fluocinolone acetonide, 0.025%, otic solution seems to be efficacious and safe in treating acute otitis externa (AOE) compared with ciprofloxacin, 0.3%, or fluocinolone acetonide, 0.025%, otic solution alone. Objective To evaluate the superiority of ciprofloxacin, 0.3%, plus fluocinolone acetonide, 0.025%, otic solution compared with ciprofloxacin, 0.3%, or fluocinolone acetonide, 0.025%, otic solution alone in treating AOE. Design, Setting, and Participants A phase 3 randomized, double-blind, active-controlled clinical trial was conducted between August 1, 2017, and September 14, 2018, at 36 centers in the US. The study population comprised 493 patients aged 6 months or older with AOE of less than 21 days' duration with otorrhea, moderate or severe otalgia, and edema, as well as a Brighton grading of II or III (tympanic membrane obscure but without systemic illness). Statistical analysis was performed from November 14, 2018, to February 14, 2019. Interventions Participants were randomly assigned to receive ciprofloxacin plus fluocinolone, ciprofloxacin, or fluocinolone twice daily for 7 days and were evaluated on day 1 (visit 1; baseline), days 3 to 4 (visit 2; conducted via telephone), days 8 to 10 (visit 3; end of treatment), and days 15 to 17 (visit 4; test of cure). Main Outcomes and Measures The primary outcome was therapeutic cure (clinical and microbiological) at the end of the treatment period. The principal secondary end point was the time to end of ear pain. Efficacy analyses were conducted in the microbiological intent-to-treat population, clinical intent-to-treat population, and microbiological intent-to-treat population with Pseudomonas aeruginosa and Staphylococcus aureus. Results A total of 493 patients (254 female patients [51.5%]; mean [SD] age, 38.2 [23.1] years) were randomized (197 to receive ciprofloxacin plus fluocinolone, 196 to receive ciprofloxacin, and 100 to receive fluocinolone). Therapeutic cure in the modified intent-to-treat population with ciprofloxacin plus fluocinolone (63 of 103 [61.2%]) was statistically comparable to that of ciprofloxacin (49 of 91 [53.8%]; difference in response rate, 7.3%; 95% CI, -6.6% to 21.2%; P = .30) and fluocinolone (20 of 45 [44.4%]; difference in response rate, 16.7%; 95% CI, -0.6% to 34.0%; P = .06) at visit 3 and significantly superior to ciprofloxacin at visit 4 (90 of 103 [87.4%] vs 69 of 91 [75.8%]; difference in response rate, 11.6%; 95% CI, 0.7%-22.4%; P = .04). A statistically faster resolution of otalgia was achieved among patients treated with ciprofloxacin plus fluocinolone (median, 5.0 days [range, 4.2-6.3 days]) vs ciprofloxacin (median, 5.9 days [range, 4.3-7.3 days]; 95% CI, 4.3-7.3 days; P = .002) or fluocinolone (median, 7.7 days [range, 6.7-9.0 days]; 95% CI, 6.7-9.0 days; P < .001). Ciprofloxacin plus fluocinolone demonstrated statistical superiority in sustained microbiological response vs ciprofloxacin (94 of 103 [91.3%] vs 74 of 91 [81.3%]; difference in response rate, 9.9%; 95% CI, 0.3%-19.6%; P = .04) and fluocinolone (34 of 45 [75.6%]; difference in response rate, 15.7%; 95% CI, 2.0%-29.4%; P = .01) and in the microbiological outcome vs fluocinolone by visit 3 (99 of 103 [96.1%] vs 37 of 45 [82.2%]; difference in response rate, 13.9%; 95% CI, 2.1%-25.7%; P = .01) and ciprofloxacin by visit 4 (97 of 103 [94.2%] vs 77 of 91 [84.6%]; difference in response rate, 9.6%; 95% CI, 0.9%-18.2%; P = .02). Fifteen adverse events related to study medications were registered, all of which were mild or moderate. Conclusions and Relevance Ciprofloxacin, 0.3%, plus fluocinolone acetonide, 0.025%, otic solution was efficacious and safe in treating AOE but did not demonstrate superiority vs ciprofloxacin, 0.3%, or fluocinolone acetonide, 0.025%, otic solutions alone in the main study end point of therapeutic cure.

Abstract
OBJECTIVE Insertion of tympanostomy tubes is the most common ambulatory surgery performed on children in the United States. Tympanostomy tubes are most often inserted because of persistent middle ear fluid, frequent ear infections, or ear infections that persist after antibiotic therapy. All these conditions are encompassed by the term otitis media (middle ear inflammation). This guideline update provides evidence-based recommendations for patient selection and surgical indications for managing tympanostomy tubes in children. The guideline is intended for any clinician involved in managing children aged 6 months to 12 years with tympanostomy tubes or children being considered for tympanostomy tubes in any care setting as an intervention for otitis media of any type. The target audience includes specialists, primary care clinicians, and allied health professionals. PURPOSE The purpose of this clinical practice guideline update is to reassess and update recommendations in the prior guideline from 2013 and to provide clinicians with trustworthy, evidence-based recommendations on patient selection and surgical indications for managing tympanostomy tubes in children. In planning the content of the updated guideline, the guideline update group (GUG) affirmed and included all the original key action statements (KASs), based on external review and GUG assessment of the original recommendations. The guideline update was supplemented with new research evidence and expanded profiles that addressed quality improvement and implementation issues. The group also discussed and prioritized the need for new recommendations based on gaps in the initial guideline or new evidence that would warrant and support KASs. The GUG further sought to bring greater coherence to the guideline recommendations by displaying relationships in a new flowchart to facilitate clinical decision making. Last, knowledge gaps were identified to guide future research. METHODS In developing this update, the methods outlined in the American Academy of Otolaryngology-Head and Neck Surgery Foundation's "Clinical Practice Guideline Development Manual, Third Edition: A Quality-Driven Approach for Translating Evidence Into Action" were followed explicitly. The GUG was convened with representation from the disciplines of otolaryngology-head and neck surgery, otology, pediatrics, audiology, anesthesiology, family medicine, advanced practice nursing, speech-language pathology, and consumer advocacy. ACTION STATEMENTS The GUG made strong recommendations for the following KASs: (14) clinicians should prescribe topical antibiotic ear drops only, without oral antibiotics, for children with uncomplicated acute tympanostomy tube otorrhea; (16) the surgeon or designee should examine the ears of a child within 3 months of tympanostomy tube insertion AND should educate families regarding the need for routine, periodic follow-up to examine the ears until the tubes extrude.The GUG made recommendations for the following KASs: (1) clinicians should not perform tympanostomy tube insertion in children with a single episode of otitis media with effusion (OME) of less than 3 months' duration, from the date of onset (if known) or from the date of diagnosis (if onset is unknown); (2) clinicians should obtain a hearing evaluation if OME persists for 3 months or longer OR prior to surgery when a child becomes a candidate for tympanostomy tube insertion; (3) clinicians should offer bilateral tympanostomy tube insertion to children with bilateral OME for 3 months or longer AND documented hearing difficulties; (5) clinicians should reevaluate, at 3- to 6-month intervals, children with chronic OME who do not receive tympanostomy tubes, until the effusion is no longer present, significant hearing loss is detected, or structural abnormalities of the tympanic membrane or middle ear are suspected; (6) clinicians should not perform tympanostomy tube insertion in children with recurrent acute otitis media who do not have middle ear effusion in either ear at the time of assessment for tube candidacy; (7) clinicians should offer bilateral tympanostomy tube insertion in children with recurrent acute otitis media who have unilateral or bilateral middle ear effusion at the time of assessment for tube candidacy; (8) clinicians should determine if a child with recurrent acute otitis media or with OME of any duration is at increased risk for speech, language, or learning problems from otitis media because of baseline sensory, physical, cognitive, or behavioral factors; (10) the clinician should not place long-term tubes as initial surgery for children who meet criteria for tube insertion unless there is a specific reason based on an anticipated need for prolonged middle ear ventilation beyond that of a short-term tube; (12) in the perioperative period, clinicians should educate caregivers of children with tympanostomy tubes regarding the expected duration of tube function, recommended follow-up schedule, and detection of complications; (13) clinicians should not routinely prescribe postoperative antibiotic ear drops after tympanostomy tube placement; (15) clinicians should not encourage routine, prophylactic water precautions (use of earplugs or headbands, avoidance of swimming or water sports) for children with tympanostomy tubes.The GUG offered the following KASs as options: (4) clinicians may perform tympanostomy tube insertion in children with unilateral or bilateral OME for 3 months or longer (chronic OME) AND symptoms that are likely attributable, all or in part, to OME that include, but are not limited to, balance (vestibular) problems, poor school performance, behavioral problems, ear discomfort, or reduced quality of life; (9) clinicians may perform tympanostomy tube insertion in at-risk children with unilateral or bilateral OME that is likely to persist as reflected by a type B (flat) tympanogram or a documented effusion for 3 months or longer; (11) clinicians may perform adenoidectomy as an adjunct to tympanostomy tube insertion for children with symptoms directly related to the adenoids (adenoid infection or nasal obstruction) OR in children aged 4 years or older to potentially reduce future incidence of recurrent otitis media or the need for repeat tube insertion.

Serous otitis media: Clinical and therapeutic considerations, including dexamethasone (C 22H 29FO 5) intratympanic injection. Exp Ther Med 2022; 23:125. [PMID: 34970348 PMCID: PMC8713185 DOI: 10.3892/etm.2021.11048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2021] [Accepted: 08/02/2021] [Indexed: 11/13/2022] Open
Abstract
Serous otitis media (SOM) occurs in children and constitutes one of the most significant causes of hearing loss in young age, posing as an important risk factor for long-term hearing loss. SOM is underdiagnosed, most frequently in infants, or the appointment to the ENT doctor is delayed due to non-acute symptomatology. The aim of the present study was to assess 285 patients with SOM diagnosed within a two-year span. The etiology and pathology of hearing loss in patients with different age groups were examined. The importance of a clinical examination and tympanometry was emphasized as absolutely necessary for a correct diagnosis. Treatment targeted Eustachian Tube permeabilization for satisfactory long-term middle ear aeration. Nasal drops with vasoconstrictor drugs (phenylephrine) and disinfectant (colloidal silver 1%) were commonly used, but some patients also benefitted from dexamethasone intratympanic injection. Patients were evaluated at the end of the treatment and follow-up occurred at one month, one year and three years later.

Abstract
Acute otitis externa (AOE), also known as ‘swimmer's ear’, is a common acute problem. It is one of the most common ED presentations. Atypical organisms, recalcitrant disease and antibiotic options contribute to making AOE a clinical challenge. There are a number of red flags associated with AOE which require consideration when treating patients with AOE. We discuss an evidence‐based approach to management of AOE in the emergency setting, with indications for specialist referral.

Abstract
BACKGROUND Acute otitis externa (AOE), is a common infectious disease affecting children and adults. Its peak prevalence is around the summer months, it involves the external auditory canal and in most cases is due to bacterial agents. METHODS This is a retrospective observational analytical case-based study involving all consecutive patients under the age of 18 years old presenting with AOE to a pediatric emergency department. RESULTS We collected data from 337 patients under 18 years of age with 344 visits to the Emergency Department, between the years 2011-2018. Nearly half of the visits presented during the summer months. Children were divided into two subgroups: hospitalized and non-hospitalized. Median hospitalization time was 3 days. The hospitalized sub-group had higher rates of failed treatment, as well as higher rates of external ear canal edema, systemic fever, canal discharge and auricular edema. On multivariable analysis the following variables had the strongest correlation for hospital admission: auricular edema (OR 27.98), otorrhea (OR 1.82), narrowing of the ear canal by more than 50% (OR 1.91), fever (OR 2.92), and previous systemic treatment (OR 2.53). Pseudomonas aeruginosa (PA) was isolated in 78% of cultures in the hospitalized sub-group. All PA strains were sensitive to ciprofloxacin. CONCLUSIONS This study highlights the main clinical variables which may predict hospitalization among children with AOE as well as the dominant role of sensitive strains of PA in the pathogenesis of this condition in children.

Case Rep Otolaryngol 2020; 2020:8874754. [PMID: 33204559 PMCID: PMC7665930 DOI: 10.1155/2020/8874754] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2020] [Revised: 10/15/2020] [Accepted: 10/26/2020] [Indexed: 11/29/2022] Open
Abstract
INTRODUCTION Necrotising otitis externa (NOE) is a rare life-threatening complication of simple otitis externa which can be difficult to diagnose and manage. It is very rarely centred on the temporomandibular joint (TMJ). Fungi cause NOE in approximately 5-20% of patients, and a high index of suspicion is required for diagnosis, particularly when there is no improvement with prolonged topical and intravenous antibiotic therapy. OBJECTIVE To report a novel case of fungal NOE centred on the left TMJ in an immunocompromised adult male with a focus on investigations and optimal management. Case Report. A 67-year-old male with comorbid chronic renal impairment presented to our otolaryngology department with prolonged left otalgia and otorrhoea. Subsequent cross-sectional imaging demonstrated left NOE centred on the TMJ. Poor resolution with prolonged courses of systemic and topical anti-pseudomonal antibiotics prompted maxillofacial surgical input for left TMJ exploration, washout, and biopsy from the joint capsule. The causative organism was identified as Aspergillus flavus on PCR analysis. The patient was successfully treated with oral posaconazole and repeated topical insertions of amphotericin B-soaked ribbon gauze to the left ear. Discussion. A combination of various imaging modalities including CT, MRI, Tc-99, and gallium-67 are utilised in clinical practice both to diagnose NOE and subsequently monitor disease progression or resolution. Immunocompromised patients with confirmed fungal NOE may require a combination of treatments including surgical debridement and prolonged antifungal therapy for a number of months, if not lifelong, treatment. Initiating empirical antifungal therapy may be justified in some patients. However, this should be judged on a case-by-case basis and guided by discussion with the local microbiology and infectious diseases departments. However, there is no national guideline or consensus regarding treatment of these patients, especially in cases of fungal NOE.

Abstract
BACKGROUND Antibiotic resistant bacteria particularly extended-spectrum beta lactamase (ESBL) producing are of major concern for management of outpatients. They can spread rapidly and are associated with poor patient outcome. However, there is scarcity of information on ear infection with ESBL producing bacteria in Ethiopia. Therefore, this study investigates the prevalence of ear infection with ESBL producing bacteria among outpatients attending Felegehiwot Referral Hospital, Northwest Ethiopia. METHODS A hospital based cross-sectional study was conducted from May, 2018 to January, 2019. Demographic and clinical data were collected with face to face interview and were complemented with patient card review. Ear discharge specimens were collected from study participants using swab technique. All ear swab specimens were cultured using standard microbiological techniques. The ESBL producing bacteria were detected by double disc synergy test and interpreted based on Clinical and laboratory Standards Institute Guidelines. Chi-square and fisher's exact tests were calculated to check association between variables. RESULTS A total of 236 patients (male = 138 and female = 98) with ear infection took part in the study. The median age of the participants was 20years. Overall, 10 (4.23%, 95%CI; 2.3-7.6%) of patients had ear infection with ESBL producing bacteria. Other chronic illnesses (p = 0.003), history of hospital visit and treatment (p = 0.006) and history of antibiotic use without physician's prescription (p<0.001) had significant association with prevalence of ESBL producing bacteria in ear infection. The proportion of ear infection with ESBL producing P.mirabilis, P.aeruginosa and K.pneumoniae were 4 (1.7%), 3 (1.3%) and 2 (0.8%), respectively. All ESBL producing isolates were MDR (100%). Overall, 58 (43%) species were MDR. P.aeruginosa was the leading MDR isolate 29 (53.7%).For all bacterial isolates of ear infection, ampicillin(93.3%) and amoxicillin-clavulanic acid (58.5%) revealed high level of resistance whereas low resistance rates were observed for ciprofloxacin (5.2%), third generation cephalosporin (11.9-20%) and aztreonam (16.3%). CONCLUSIONS Ear infection due to ESBL producing bacteria coupled with high levels of MDR is becoming a growing concern for outpatients in the study area. Regular detection of these bacteria and wise use of antibiotics are needed to stop the spread of this form of resistance.

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.

Abstract
OBJECTIVE The aim of this experimental study was to compare the dose-related effect of topical thymoquinone (TQ) with other topical agents used in the management of acute otitis externa (AOE) in a rat model. MATERIALS AND METHODS Forty-eight male Wistar albino rats were divided into six groups each with eight rats per group. Group I was the control group with no external otitis, whereas external otitis were created in the other five groups (study groups). Dexamethasone, 0.1% TQ, 0.4% TQ, ciprofloxacin, and 0.9% saline (NaCl) drops was applied once daily in Groups II-VI, respectively. The treatment was administered regularly for 10 days. Pathologic and microbiologic evaluation were performed. Pathologically, the thicknesses of the stroma and the epithelium in the external auditory canal (EAC) were measured using an occulometer. Edema in the stroma, density of inflammatory cells and blood vessels, presence of fibroblasts, and changes in collagen fibers in the EAC were evaluated in five different areas to obtain the area of highest concentration and classified into four grades (0=no change, 1=mild, 2=moderate, 3=severe). RESULTS The higher concentration of TQ (0.4%) was more effective than dexamethasone and 0.1% TQ with respect to antibacterial and the anti-inflammatory properties. CONCLUSION TQ, particularly at a concentration of 0.4%, may be considered for topical application alone in the treatment of AOE, without any requirement for a combined treatment.

Abstract
To analyse and discuss the clinical features and pathogenic characteristics, diagnosis and treatment of patients with otomycosis in southern China. Two hundred fifty-six patients from southern China diagnosed with otomycosis were randomly separated into two groups: the drug filling group and drug smearing group. Patients in the drug filling group were first examined and then had the pathogenic secretions in their external auditory canals cleared by otoendoscopy. Then, the local antifungal cream triamcinolone acetonide clotrimazole was injected into the external auditory canal. The same treatment was undertaken 1 week later and repeated once or twice more. Patients in the drug smearing group were also treated by otoendoscopy. Then, they were told to smear their external auditory canals once per day with the antifungal cream. All cases were followed for more than 6 months after the 3- to 4-week treatment. The main symptoms and otoendoscopic examination were used to evaluate the prognosis. Aspergillus was the commonest fungus. The cure rate was 93% in the drug filling group and 81% in the drug smearing group. Otomycosis is very common in southern China, but it lacks characteristic features in its early stages. Once diagnosed, the local lesions in the external auditory canal should be cleared thoroughly using otoendoscopy, and then, the local antifungal cream is injected into external auditory canal. The cure rate can be significantly improved with the foregoing treatment.

Abstract
RATIONALE Although an ototoxicity is well-known as adverse event of the radiotherapy, it is not widely known that immunosuppressed patients who underwent radiotherapy in head and neck region have risk of malignant external otitis. PATIENT CONCERNS A 68-year-old man with diabetes, who had been diagnosed as intraosseous squamous cell carcinoma of the right mandible, underwent surgical resection. He received a total of 60 Gy/30Fr postoperative radiation. Four months after the course of radiation, he suffered from right aural fullness, otalgia and otorrhea. DIAGNOSES Clinical examination revealed granulation and existence of Pseudomonas aeruginosa in the external auditory canal. Computed tomography showed expansive inflammation and erosion in the temporal bone. The patient is elderly and diabetes. These findings led to the diagnosis of malignant external otitis. INTERVENTIONS The ear irrigation and administration of quinolones were started. Afterwards, fistula was formed in the oral cavity, and connected to the right external auditory canal. Therefore, irrigations were performed not only from ear but also from the oral fistula. OUTCOMES Eight weeks after starting treatment, the malignant external otitis was completely healed. LESSONS Physicians should raise awareness of malignant external otitis in immunosuppressed patients with oral cancer after radiotherapy.

Abstract
OBJECTIVE Otowicks are used to treat otitis externa with significant ear canal oedema. This study investigates how well drops penetrate through to reach the deep canal and whether it is safe to leave otowicks in the canal for more than 2 days. METHODS Sterile otowicks were inserted into mock ear canals and vertically over pseudomonas-seeded agar plates whilst gentamicin or ciprofloxacin drops were administered. The time taken for drops to penetrate through the otowick was recorded. Separately, pseudomonas-seeded otowicks were treated with saline or antibacterial drops. The penetrating drops were observed for bacterial growth on sterile agar. RESULTS It took six drops before penetration occurred for both antibiotics. When sterile saline drops were applied to bacterially contaminated otowicks, the penetrating drops displayed bacterial growth on agar, indicating that pseudomonas penetrated through the otowick. However, when antibiotic drops were applied, penetrating drops showed no bacterial growth on the corresponding agar plate. CONCLUSION Bacteria can penetrate otowicks but this is prevented by continuous application of antibacterial ear drops. Ear wicks need priming with six drops before starting a regimen, so that the initial dose is fully absorbed.

Abstract
Ear infections are a commonly-occurring problem that can affect people of all ages. Treatment of these pathologies usually includes the administration of topical or systemic antibiotics, depending on the location of the infection. In this context, we sought to address the feasibility of a single-application slow-releasing therapeutic formulation of an antibiotic for the treatment of otitis externa. Thixotropic hydrogels, which are gels under static conditions but liquefy when shaken, were tested for their ability to act as drug controlled release systems and inhibit Pseudomonas aeruginosa and Staphylococcus aureus, the predominant bacterial strains associated with outer ear infections. Our overall proof of concept, including in vitro evaluations reflective of therapeutic ease of administration, formulation stability, cytocompatibility assessment, antibacterial efficacy, and formulation lifespan, indicate that these thixotropic materials have strong potential for development as otic treatment products.

Abstract
AbstractObjective:To determine the expansile and absorptive properties of the expandable ear wick when tested with commonly prescribed ear drop preparations.Design:This in vitro study assessed wick expansion and absorption of drops when different ear drop preparations were applied. Nine commonly used ear drop preparations were tested (Gentisone HC, Sofradex, Otomize, Betnesol, Exocin, Canesten, Locorten-Vioform, EarCalm and ichthammol glycerin) with a standard expandable ear wick.Main outcome measures:Weight, length and width of otowick following exposure to ear drops.Results:There was a marked difference in the absorption and expansion of the otowick when different drops were used. This corresponded to the aqueous or oil base of each preparation. All aqueous ear drop preparations (i.e. Gentisone HC, Sofradex, Otomize, Betnesol, Exocin and EarCalm) produced similar rates of absorption into, and expansion of, the otowick. The oil-based ear drop preparations (i.e. Canesten, Locorten-Vioform and ichthammol glycerin) failed to expand the wick and showed poor rates of absorption into the wick.Conclusion:Expandable ear wicks should only be used in conjunction with aqueous ear drops. When using expandable otowicks as an adjunct to treating fungal otitis externa, acetic acid ear drops should be prescribed, as all other anti-fungal drops are oil-based.

Abstract
OBJECTIVE: To determine the efficacy of topical antimicrobials for acute otitis externa. STUDY DESIGN: Systematic review and random effects metaanalysis of randomized, controlled trials with parallel groups permitting one or more of the following comparisons: antimicrobial vs placebo, antiseptic vs antimicrobial, quinolone antibiotic vs nonquinolone antibiotic, steroid-antimicrobial vs antimicrobial, or antimicrobial-steroid vs steroid. RESULTS: Twenty trials met inclusion criteria and 18 had data suitable for pooling. Topical antimicrobials increased absolute clinical cure rates over placebo by 46% (95% confidence interval [CI], 29% to 63%) and bacteriologic cure rates by 61% (95% CI, 46% to 76%). No significant differences were noted in clinical cure rates for other comparisons, except that steroid alone increased cure rates by 20% compared with steroid plus antibiotic (95% CI, 3% to 38%). Quinolone drops increased bacteriologic cure rates by 8% compared with nonquinolone antibiotics (95% CI, 1% to 16%), but had statistically equivalent rates of clinical cure and adverse events CONCLUSION: Topical antimicrobial is highly effective for acute otitis externa with clinical cure rates of 65% to 80% within 10 days of therapy. Minor differences were noted in comparative efficacy, but broad confidence limits containing small effect sizes make these of questionable clinical significance. SIGNIFICANCE: Summary estimates from the 13 meta-analyses can be used to facilitate evidence-based management recommendations and clinical practice guideline development. © 2006 American Academy of Otolaryngology-Head and Neck Surgery Foundation, Inc.

Abstract
OBJECTIVE To determine if providers prescribe more affordable topical antibacterial therapy for patients who are economically disadvantaged or come from economically disadvantaged communities. STUDY DESIGN Prescription drug database review. SETTING Large academic hospital network. SUBJECTS AND METHODS Ototopical prescription records of 2416 adults and children presenting with acute and chronic otologic infections from 2009 to 2013 were reviewed. Prescription, patient, provider, and institution variables including diagnosis, prescription type, demographics, health insurance status, healthcare provider type and setting were analyzed. RESULTS Otitis externa and acute otitis media were the most common diagnoses. Non-OHNS (Otolaryngology-Head and Neck Surgery) providers served 82% of all patients. OHNS providers prescribed proportionally less fluoroquinolone, and more brand-name antibiotics compared to non-OHNS providers. Adults were more likely to receive a non-fluoroquinolone antibiotic and a generic prescription versus pediatric patients. Patients who self-identified as 'white' ethnicity received proportionally more fluoroquinolone prescriptions than patients who identified as 'non-white,' but there was no difference in provider type. The proportion of fluoroquinolone prescriptions was significantly higher in patients from low-poverty counties, however poverty level was not associated with patients seeing a particular provider type. The majority of our patients had commercial insurance, followed by Medicaid. Medicare patients had the lowest proportion of fluoroquinolone antibiotic prescriptions, and were less likely to receive fluoroquinolone prescriptions versus commercial insurance. Non-insured patients received proportionally more generic versus brand prescriptions than insured patients. CONCLUSION Our results indicate potential provider, patient demographic, and financial factors producing considerable variability in the prescribing patterns for topical antibiotics for common otologic infections.

Abstract
External otitis is a diffuse inflammation around the external auditory canal and auricle, which is often occurred by microbial infection. This disease is generally treated using antibiotics, but the frequent occurrence of antibiotic resistance requires the development of new antibiotic agents. In this context, unexplored bioactive natural candidates could be a chance for the production of targeted drugs provided with antimicrobial activity. In this paper, microbial pathogens were isolated from patients with external otitis using ear swabs for over one year, and the antimicrobial activity of the two methanol extracts from selected marine (Dunaliella salina) and freshwater (Pseudokirchneriella subcapitata) microalgae was tested on the isolated pathogens. Totally, 114 bacterial and 11 fungal strains were isolated, of which Staphylococcus spp. (28.8%) and Pseudomonas aeruginosa (P. aeruginosa) (24.8%) were the major pathogens. Only three Staphylococcus aureus (S. aureus) strains and 11 coagulase-negative Staphylococci showed resistance to methicillin. The two algal extracts showed interesting antimicrobial properties, which mostly inhibited the growth of isolated S. aureus, P. aeruginosa, Escherichia coli, and Klebsiella spp. with MICs range of 1.4 × 109 to 2.2 × 1010 cells/mL. These results suggest that the two algae have potential as resources for the development of antimicrobial agents.

Abstract
The American Academy of Otolaryngology-Head and Neck Surgery Foundation clinical practice guidelines address a variety of otolaryngologic diseases and/or procedures. It may seem reasonable to create these guidelines by assembling a team of expert clinicians familiar with the pertinent clinical issues and the available evidence, with debate and eventual agreement leading to recommendations. However, trustworthy clinical practice guidelines are in fact created via a defined process to assemble a guideline development group composed of diverse stakeholders: clinician generalists and specialists, content experts, methodologists, physicians and nonphysicians, patients, and advocates. Such a guideline development group can create a valuable and trusted guideline for clinicians and affected patients.

Abstract
Gentamicin is an aminoglycoside antibiotic widely used in combination with dimethyl sulphoxide (DMSO) in topical drug formulations. It is not known, however, whether DMSO can enhance the permeation of gentamicin through biological membranes, leading to oto- and nephrotoxic side effects. A simple and reliable high-performance liquid chromatographic (HPLC) method was applied for the quantitative determination of gentamicin collected from the apical and basolateral compartments of the porcine intestinal epithelial cell line IPEC-J2 cell monolayer using fluorometric derivatisation of the analyte with fluorenylmethyloxycarbonyl chloride (FMOC) prior to chromatographic run in the presence and absence of 1% DMSO. The lack of change in transepithelial electrical resistance (TER) demonstrated that gentamicin and 1% DMSO did not affect IPEC-J2 cell monolayer integrity via the disruption of cell membranes. Chromatographic data also ascertained that gentamicin penetration across the cell monolayer even in the presence of 1% DMSO was negligible at 6 h after the beginning of apical gentamicin administration. This study further indicates that the addition of this organic solvent does not increase the incidence of toxic effects related to gentamicin permeation.

Abstract
OBJECTIVE We aimed to evaluate the clinical efficacy of ciprofloxacin plus fluocinolone acetonide (antibiotic plus corticosteroid) ear drops compared to ciprofloxacin (antibiotic) ear drops in diffuse otitis externa. METHODS This was a multicentre, randomised, parallel-group, double-blind study involving 590 patients of both sexes aged 7 years or older. RESULTS The rate of clinical cure was higher (p = 0.01) with ciprofloxacin plus fluocinolone acetonide than with ciprofloxacin alone. The mean total symptom score was lower with ciprofloxacin plus fluocinolone acetonide (p = 0.005). No differences were found in the percentage of patients reporting resolution of otalgia between patients receiving ciprofloxacin plus fluocinolone acetonide and patients receiving only ciprofloxacin. Resolution of oedema and otorrhoea (p = 0.003 and p = 0.002, respectively) was higher with ciprofloxacin plus fluocinolone acetonide, as was eradication or presumed eradication (p = 0.003). There were eight mild adverse events, three with the ciprofloxacin plus fluocinolone acetonide combination (not related to the treatment) and five when ciprofloxacin was administered alone (directly related to the treatment). CONCLUSIONS Ciprofloxacin plus fluocinolone acetonide is a more effective treatment for diffuse otitis externa than ciprofloxacin alone. The ciprofloxacin plus fluocinolone acetonide combination also has an excellent safety profile.

Abstract
Context: Self-ear-cleaning has been reported to be common from several hospital-based studies and it has been associated with some diseases of the ear. Aims: To determine community-based prevalence of self-ear-cleaning and its sociodemographic correlates among educated young adults in Nigeria. Settings and Design: A cross-sectional survey conducted in a National Youth Service Corps camp in Nigeria. Subjects and Methods: Semistructured questionnaires were administered on a randomly selected sample of 1280 respondents. The outcome variable was self-ear-cleaning. Independent variables were sociodemographic variables, materials used and ear-cleaning habits. Statistical Analysis Used: Statistical Package for the Social Sciences (SPSS) version 15 was utilized for univariate, bivariate, and multiple logistic regression analysis. Results: There were 1012 respondents (M: F = 1.05:1). Mean age was 25.3 (standard deviation, 2.34). Prevalence of self-ear-cleaning was 93.4%. Mean age at first cleaning was 7.6 years. Cotton buds were the most frequently used objects (in 85.1%). Prevalence was high irrespective of sociodemographic class, significantly higher among females (χ2 = 4.549, P = 0.033), those who believed the habit was beneficial (χ2 = 114.185, P < 0.001) and those whose parents and siblings practiced the habit. Significant predictive factors were self-ear-cleaning in respondent's father [odds ratio (OR) P = 0.011) and owning cotton buds (OR = 0.192, P = 0.007). Conclusions: Self-ear-cleaning is almost universal. Most of the population is, therefore, at risk of possible harmful effects. Also, medical advice against self-ear-cleaning is not widely known. Rather, the erroneous perception that self-ear-cleaning is beneficial is common. Collaborative health education efforts targeted at families and schools and campaigns and advocacy for legislation regulating the sale of cotton buds are recommended.

Abstract
The American Academy of Otolaryngology--Head and Neck Surgery Foundation (AAO-HNSF) has published a supplement to this issue featuring the updated Clinical Practice Guideline: Acute Otitis Externa, as a supplement to Otolaryngology-Head and Neck Surgery. To assist in implementing the guideline recommendations, this article summarizes the rationale, purpose, and key action statements. The 8 recommendations developed address appropriate diagnosis of acute otitis externa (AOE) and the use of oral and topical antimicrobials and highlight the need for adequate pain relief. An updated guideline is needed due to new clinical trials, new systematic reviews, and the lack of consumer participation in the initial guideline development group.

Abstract
Objective This clinical practice guideline is an update and replacement for an earlier guideline published in 2006 by the American Academy of Otolaryngology—Head and Neck Surgery Foundation. This update provides evidence-based recommendations to manage acute otitis externa (AOE), defined as diffuse inflammation of the external ear canal, which may also involve the pinna or tympanic membrane. The variations in management of AOE and the importance of accurate diagnosis suggest a need for updating the clinical practice guideline. The primary outcome considered in this guideline is clinical resolution of AOE. Purpose The primary purpose of the original guideline was to promote appropriate use of oral and topical antimicrobials for AOE and to highlight the need for adequate pain relief. An updated guideline is needed because of new clinical trials, new systematic reviews, and the lack of consumer participation in the initial guideline development group. The target patient is aged 2 years or older with diffuse AOE. Differential diagnosis will be discussed, but recommendations for management will be limited to diffuse AOE, which is almost exclusively a bacterial infection. This guideline is intended for primary care and specialist clinicians, including otolaryngologists–head and neck surgeons, pediatricians, family physicians, emergency physicians, internists, nurse practitioners, and physician assistants. This guideline is applicable in any setting in which patients with diffuse AOE would be identified, monitored, or managed. Action Statements The development group made strong recommendations that (1) clinicians should assess patients with AOE for pain and recommend analgesic treatment based on the severity of pain and (2) clinicians should not prescribe systemic antimicrobials as initial therapy for diffuse, uncomplicated AOE unless there is extension outside the ear canal or the presence of specific host factors that would indicate a need for systemic therapy. The development group made recommendations that (1) clinicians should distinguish diffuse AOE from other causes of otalgia, otorrhea, and inflammation of the external ear canal; (2) clinicians should assess the patient with diffuse AOE for factors that modify management (nonintact tympanic membrane, tympanostomy tube, diabetes, immunocompromised state, prior radiotherapy); (3) clinicians should prescribe topical preparations for initial therapy of diffuse, uncomplicated AOE; (4) clinicians should enhance the delivery of topical drops by informing the patient how to administer topical drops and by performing aural toilet, placing a wick, or both, when the ear canal is obstructed; (5) clinicians should prescribe a non-ototoxic preparation when the patient has a known or suspected perforation of the tympanic membrane, including a tympanostomy tube; and (6) clinicians should reassess the patient who fails to respond to the initial therapeutic option within 48 to 72 hours to confirm the diagnosis of diffuse AOE and to exclude other causes of illness.

Abstract
Acute otitis externa, also known as 'swimmer's ear', is a common disease of children, adolescents and adults. While chronic suppurative otitis media or acute otitis media with tympanostomy tubes or a perforation can cause acute otitis externa, both the infecting organisms and management protocol are different. This practice point focuses solely on managing acute otitis externa, without acute otitis media, tympanostomy tubes or a perforation being present.

Abstract
OBJECTIVE To carry out a systematic review of scientific evidence available about necrotizing otitis externa, emphasizing epidemiologic data, diagnosis criteria, treatment protocols, follow-up criteria, prognosis factors, and chronologic evolution. DATA SOURCES PubMed/MEDLINE and the Cochrane Database of Systematic Reviews were searched for publications in English and French languages, between 1968 and October 1, 2011. STUDY SELECTION We included publications of all types including at least 6 cases. We excluded publications focused on cranial base osteomyelitis not originating from the external ear and publications limited to a specific population. DATA EXTRACTION We assessed publication quality according to international guidelines. DATA SYNTHESIS For each publication, data were entered in a spreadsheet software for analysis. We excluded individual data already published in other studies or reviews. CONCLUSION Our review revealed the absence of strong scientific evidence regarding diagnosis criteria, treatment protocols and follow-up criteria. This implies the use of highly empirical indexes of suspicion in clinical practice. Our review confirmed the existence of a typical but not exclusive population at risk (aged, male, and diabetic patient) and also revealed major issues: lack of primary prevention in population at risk, delays before referral and management, bacteriologic issues caused by antibiotic misuse (agent identification problems, rise of resistant strains), persistence of recurrent cases. A better diffusion of medical information should help improve the management of this severe disease.

Abstract
We present a case of an 81-year-old man who was diagnosed with a necrotising (malignant) otitis externa (NOE). Initial biopsies from the external auditory canal showed scanty squamous epithelium but no evidence of malignancy. Despite an initial improvement on intravenous antibiotics and subsequent discharge from hospital, the patient returned with worsening otalgia. Following readmission to the hospital, intravenous antibiotics were restarted. Despite this, the patient developed a lower motor neurone palsy of cranial nerve VII on the ipsilateral side of the pain. He was taken to the theatre for an exploration of the left mastoid with further biopsies. Adenocarcinoma was diagnosed histologically and the patient was started on palliative radiotherapy. This case adds to the known literature on metastatic disease in the temporal bone and highlights the need to exclude malignancy in cases of NOE.

Abstract
OBJECTIVE To achieve a European consensus about the best-evidence informed-management of patients with common otologic-related problems. DESIGN Consensus process, supported by the European Academy of Otology & Neuro-Otology. SETTING The European Academy of Otology & Neuro-Otology. METHODS A guideline of a specific disease should include evidence-informed recommendations about questions relating to treatment, prognosis, and diagnosis. A standardized method to design guideline questions to search for evidence and to grade the quality of available evidence results in an overview of the best available literature. Experts achieve a consensus on best practice and articulate recommendations on evidence-based actions to be taken in patient care accordingly. The assets of such evidence-based consensus usually are the opinion of experts and arguments on availability, transferability, applicability, and affordability. DISCUSSION The volume of new information increases at a staggering pace. As a result, there is an increasing demand for consistent systematic management of the available evidence. Systematic filtering of available evidence will help clinicians to find and apply best available and latest evidence efficiently and quickly. CONCLUSION Despite the otologic line of approach, the present article provides a step-by-step "guideline development instruction manual," which could be used within other medical specialties.

Abstract
OBJECTIVES/HYPOTHESIS To determine the ototoxic potential of aluminum acetate (0.5%)/benzethonium chloride (0.03%) otic solution in the chinchilla animal model. STUDY DESIGN A randomized, prospective, controlled study was conducted in the chinchilla animal model. METHODS Fourteen female chinchillas were used. After an incision was made in each tympanic membrane, baseline auditory brainstem response measurements were performed at 16, 20, and 25 kHz. One ear was randomized to receive aluminum acetate (0.5%)/benzethonium chloride (0.03%), whereas the other ear served as the control and received 0.9% NaCl. Solutions were applied transtympanically once a day for 3 consecutive days. Postapplication auditory brainstem response measurements were done at day 7 and day 30. In half of the animals, scanning electron microscopy was done following the last auditory brainstem response measurement. RESULTS A statistically significant difference was found between the mean threshold shifts in the experimental and control ears at all frequencies on both 7 and 30 days postapplication (P < .02). Increased ossification of the cochleae was seen in experimental ears (n = 12). Scanning electron microscopy study demonstrated outer hair cell damage and/or loss in the experimental ears. No significant morphological changes were detected on scanning electron microscopy obtained from the control ears. CONCLUSIONS Application of aluminum acetate (0.5%)/benzethonium chloride (0.03%) otic solution causes hearing loss in chinchillas when a tympanic membrane perforation exists. Further studies are needed to test the effect of this otic solution on hearing. LEVEL OF EVIDENCE 4.

Abstract
Objective Insertion of tympanostomy tubes is the most common ambulatory surgery performed on children in the United States. Tympanostomy tubes are most often inserted because of persistent middle ear fluid, frequent ear infections, or ear infections that persist after antibiotic therapy. Despite the frequency of tympanostomy tube insertion, there are currently no clinical practice guidelines in the United States that address specific indications for surgery. This guideline is intended for any clinician involved in managing children, aged 6 months to 12 years, with tympanostomy tubes or being considered for tympanostomy tubes in any care setting, as an intervention for otitis media of any type. Purpose The primary purpose of this clinical practice guideline is to provide clinicians with evidence-based recommendations on patient selection and surgical indications for and management of tympanostomy tubes in children. The development group broadly discussed indications for tube placement, perioperative management, care of children with indwelling tubes, and outcomes of tympanostomy tube surgery. Given the lack of current published guidance on surgical indications, the group focused on situations in which tube insertion would be optional, recommended, or not recommended. Additional emphasis was placed on opportunities for quality improvement, particularly regarding shared decision making and care of children with existing tubes. Action Statements The development group made a strong recommendation that clinicians should prescribe topical antibiotic eardrops only, without oral antibiotics, for children with uncomplicated acute tympanostomy tube otorrhea. The panel made recommendations that (1) clinicians should not perform tympanostomy tube insertion in children with a single episode of otitis media with effusion (OME) of less than 3 months’ duration; (2) clinicians should obtain an age-appropriate hearing test if OME persists for 3 months or longer (chronic OME) or prior to surgery when a child becomes a candidate for tympanostomy tube insertion; (3) clinicians should offer bilateral tympanostomy tube insertion to children with bilateral OME for 3 months or longer (chronic OME) and documented hearing difficulties; (4) clinicians should reevaluate, at 3- to 6-month intervals, children with chronic OME who did not receive tympanostomy tubes until the effusion is no longer present, significant hearing loss is detected, or structural abnormalities of the tympanic membrane or middle ear are suspected; (5) clinicians should not perform tympanostomy tube insertion in children with recurrent acute otitis media (AOM) who do not have middle ear effusion in either ear at the time of assessment for tube candidacy; (6) clinicians should offer bilateral tympanostomy tube insertion to children with recurrent AOM who have unilateral or bilateral middle ear effusion at the time of assessment for tube candidacy; (7) clinicians should determine if a child with recurrent AOM or with OME of any duration is at increased risk for speech, language, or learning problems from otitis media because of baseline sensory, physical, cognitive, or behavioral factors; (8) in the perioperative period, clinicians should educate caregivers of children with tympanostomy tubes regarding the expected duration of tube function, recommended follow-up schedule, and detection of complications; (9) clinicians should not encourage routine, prophylactic water precautions (use of earplugs, headbands; avoidance of swimming or water sports) for children with tympanostomy tubes. The development group provided the following options: (1) clinicians may perform tympanostomy tube insertion in children with unilateral or bilateral OME for 3 months or longer (chronic OME) and symptoms that are likely attributable to OME including, but not limited to, vestibular problems, poor school performance, behavioral problems, ear discomfort, or reduced quality of life and (2) clinicians may perform tympanostomy tube insertion in at-risk children with unilateral or bilateral OME that is unlikely to resolve quickly as reflected by a type B (flat) tympanogram or persistence of effusion for 3 months or longer (chronic OME).

Abstract
Unsustainable health care costs coupled with opportunity for improvement in health care outcomes in the United States are stimulating meaningful transformation in the way we deliver care. One approach in this transformation focuses on minimizing unnecessary variation in physician practices, instead focusing on evidence-based medicine in a more uniform manner. Clinical practice guidelines contain evidence-based recommendations, articulate goals of care, and can help to reduce unnecessary variation. While thousands of clinical practice guidelines are in existence, a clinical gap exists between knowledge and clinical performance. With thoughtful guidelines implementation strategies in place, organizations can begin to close the gap and translate best practice knowledge into care. Health systems that have done this effectively have seen improved clinical outcomes, improved patient satisfaction, and lower cost per patient.

Abstract
In February 2013, the American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) released its list of 5 recommendations of diagnostic and therapeutic interventions that physicians and patients should question, as part of the American Board of Internal Medicine (ABIM) Foundation's Choosing Wisely campaign. This commentary outlines the impetus for the AAO-HNSF to join the campaign, our list of 5 recommendations, how they were developed, and our future involvement with the campaign. The AAO-HNSF's 5 recommendations are (1) don't order a computed tomography (CT) scan of the head/brain for sudden hearing loss, (2) don't prescribe oral antibiotics for uncomplicated acute tympanostomy tube otorrhea, (3) don't prescribe oral antibiotics for uncomplicated acute external otitis, (4) don't routinely obtain radiographic imaging for patients who meet diagnostic criteria for uncomplicated acute rhinosinusitis, and (5) don't obtain CT or magnetic resonance imaging in patients with a primary complaint of hoarseness prior to examining the larynx.

Abstract
BACKGROUND Guidelines translate best evidence into best practice. A well-crafted guideline promotes quality by reducing health care variations, improving diagnostic accuracy, promoting effective therapy, and discouraging ineffective-or potentially harmful-interventions. Despite a plethora of published guidelines, methodology is often poorly defined and varies greatly within and among organizations. PURPOSE The third edition of this manual describes the principles and practices used successfully by the American Academy of Otolaryngology--Head and Neck Surgery Foundation to produce quality-driven, evidence-based guidelines using efficient and transparent methodology for actionable recommendations with multidisciplinary applicability. The development process emphasizes a logical sequence of key action statements supported by amplifying text, action statement profiles, and recommendation grades linking action to evidence. New material in this edition includes standards for trustworthy guidelines, updated classification of evidence levels, increased patient and public involvement, assessing confidence in the evidence, documenting differences of opinion, expanded discussion of conflict of interest, and use of computerized decision support for crafting actionable recommendations. CONCLUSION As clinical practice guidelines become more prominent as a key metric of quality health care, organizations must develop efficient production strategies that balance rigor and pragmatism. Equally important, clinicians must become savvy in understanding what guidelines are--and are not--and how they are best used to improve care. The information in this manual should help clinicians and organizations achieve these goals.

Abstract
OBJECTIVE Acute otitis externa (AOE) is a common but preventable ear condition. Clinical guidelines issued in 2006 recommended topical treatments for uncomplicated AOE, but systemic antimicrobials appear to be commonly prescribed. The objective of this analysis was to describe pre- and postguideline prescribing patterns by clinician specialty and antimicrobial type and assess trends over time. STUDY DESIGN Retrospective longitudinal analysis of a large insurance database. SETTING Outpatient departments in the United States. METHODS Initial outpatient visits in 2004 to 2010 for AOE (excluding visits with complicating conditions) were extracted from an insurance database. Prescription drug claims were linked and categorized by clinician specialty and antimicrobial type. RESULTS The analysis included 907,261 initial outpatient visits. Use of systemic antimicrobials declined by 4.9% (95% confidence interval [CI], 4.1%, 5.7%) from 36.5% of initial visits in 2004 to 32.1% in 2010. Use of systemic antimicrobials varied by specialty. Systemic antimicrobials were prescribed in 47.1% of 2010 emergency department (ED) visits (-6.9% from 2004, 95% CI -12.3, -1.5), 25.9% of otolaryngologist visits (-1.6%, 95% CI -5.6, 2.4), and 20.4% of pediatrician visits (-6.6%, 95% CI -8.8, -4.4). Penicillins were prescribed most frequently (42.3% of systemic prescriptions in 2010), followed by cephalosporins (19.8%), erythromycin/macrolides (17.4%), and quinolones (11.1%). Opioids were prescribed in 26.4% of ED visits and 9% of outpatient visits. CONCLUSIONS Use of systemic antimicrobials declined over time, but one-third of 2010 visits resulted in systemic antimicrobials, despite exclusion of visits with complicating factors. Use of systemic antimicrobials varied by specialty. Further educational efforts and outreach to other specialties might be warranted.

Abstract
External auditory canal (EAC) carcinomas are frequently misdiagnosed. The aim of this study was to conduct a review of misdiagnosed cases and analyze the factors involved. This study was a retrospective assessment. Eighteen of 44 EAC carcinoma cases seen at the Eye and ENT Hospital were misdiagnosed. All medical records were retrospectively analyzed for the age, sex, presenting symptoms, type of misdiagnosis, computed tomographic (CT) or magnetic resonance imaging (MRI) findings, stage of the cancer, surgical approach, histopathological examination, adjunctive therapy (postoperative radiotherapy) and outcomes of treatment. Six cases were misdiagnosed as otitis media, five cases were misdiagnosed as otitis externa, and two cases were misdiagnosed as external auditory canal cholesteatomas. Other misdiagnoses were stenosis of the EAC, ear neuralgia, furuncle of the EAC, benign neoplasm of the EAC and pre-auricular fistula. Our analyses suggest that a biopsy should be conducted to obtain a histopathological diagnosis if an EAC carcinoma is suspected, in case otitis media or otitis externa does not respond to routine anti-bacterials. Head and neck MRI should be used to explore the involvement of soft tissues. Patients with bloody ear discharge and otalgia, particularly with temporal bone erosion seen in a CT scan, are highly likely to have a malignant carcinoma of the temporal bone.
